[ROM][2012.09.19] Lenovo A750 custom ROM (GB&ICS)

Please note this is a rewrite and cleanup of first post. Original firstpost is in post#3.
Here I publish the ROM's I make for the MT6575 based Lenovo Dual SIM phone
The current and advised ROM is A750_ROW_S114_cybermaus_ICS_V3.1 described in post#2 below
This is the original A750 thread, but as not everyone can post in developer threads, I also have a publicly available new Q&A thread.
I advise you post your question here (if a more advanced and development specific A750 question) or in the Q&A question.
I am not going to be policing, so you can post where you like, but I invite everyone to use this new thread for any Q&A, and this thread for ROM releases and deep development talk only. Please understand I do not know everything, so using the Q&A thread is better then PM'ing me, as that way maybe others know the answer too.
Also, I am moving file hosting to Dev-Host. So if you encounter a dead link to a ROM file, do look here in my Dev-Host folder.

ICS IceCream Sandwich
Starting 2012/09/12 I have a second flavor of ICS ROM for the A750
ICS V1 ~ V1.3 are based on the original Lenovo A750 ROM's Most people tried them, but went on to APKHOT because of multilang. There was a V2, but never released
ICS V3 and onward is based on the Lenovo P700 ROM, see below
ICS V1 series
It is a update.zip type update. If you already got S306, and rooted/gapps'ed it yourself, you could stick to that, this is the same, with some minor extra cleanup.
'Normal' cleanup actions:
- Prevented update from overwriting Recovery
- Added root (Chainfire) & gapps (CM9 120429) & Maps & Streetview
- Cleaned Chinese & SmsReg
- Replace talking Unicom bootup with silent butterfly
- Set to US/en & added MoreLocale2
- Added MobileUncle 2.0.9
Instructions for A750_S306_120530_cybermaus_ICS_V1:
Assuming you have the custom recovery. If not, flash the recovery from my 4-shared using the flash tool.
- Put S306 V1 zip file on SD card (do not unzip)
- Also put S306 V1.3 zip file on the SD card (do not unzip)
- Boot into Recovery
- First apply V1, then apply V1.3
- Potentially, clear userdata and cache, especially if you come from any S14x GB
- Reboot, and wait for it to complete.
BTW: It should probably be noted that while I packaged V1.2 and V1.3, it was again bgcngm who we have to thank for knowing how to solve the location problems.
If you already lost recovery due to the S306 OTA update, reinstall it using the flash method from first post.
Please always respond if you tested it, even if you did not like it.
Oh, and if you do like it, press the thanks button of course.
ICS V3 series
For a long time I guessed the P700 is similar to the A750, but why bother. Until I recently heard it has a multilingual ROW (Rest Of World 海外版) version!
So I took the leap, and transplanted the A750 kernel into the P700 ROM (needed because the screen driver is different), and installed it on my A750.
It works pretty well. I did not need to fix location services or gapps (though I did put the newest in there). Also did I not need to clean up any Chinese apps. And the Calender is Chinese free, and the Dialer free of Chinese city names. So I barely had to do anything. Also GAPPS TTS was in there, though I still cannot find the settings menu.
But alas, the only 'multilang' in the ROW was Vietnamese. I guess "Rest Of World" is pretty limited.
Also, for those of you that liked it, the Security App (Anti-Virus, and limit permissions per App, so sort of a firewall) is also missing. I may put it back in later, but I want to run vanilla for a while to test stability.
But it is still nice and clean, and all programs a month newer. And Chinese out of the browser/email-setup/calender/dialer. Oh, and for all of you that went to APKHOT because of the newer SIM taskbar icons: It also has the newer icons. For an ongoing list of findings in post #585
So for those of you that want to try: A750_ROW_S113_cybermaus_ICS_V3 based on P700_ROW_S113_120801.
Assuming you have the custom recovery. If not, flash the recovery from my 4-shared using the flash tool.
A750_ROW_S114_cybermaus_ICS_V3.1
Based on factory ROM P700_ROW_S114_120903, and located in my Dev_host. Similar to V3, but newer, and a few extra tweaks.
Summery of changes:
- Same as on V3, and additionally:
- Whatever Lenovo fixed in their S114 (there is a unconfirmed suggestion that it may be signal strength related)
- Different (better?) call-log and Caller-ID behavior, see post #3 below
- Prepared busybox (you need to run script /system/xbin/installbusybox as root if you want it)
- Added a tweak so USB-Debug notification is no longer shown
- Added a tweak so Wifi works on all 14 international channels (rather than only the 11 US ones, may be undone if you set a different locale)
- Kept the original S306 radio firmware (baseband). They had the same timestamp as the P700 one anyway.
Instructions:
This is a update.zip type ROM. If you are on any ICS ROM, you do not need to flash V3 first, you can directly flash V3.1"
- Put ROW_S114 zip on SD card
- Boot into recovery
- Apply zip file
- Reboot, and wait for it to complete.
- If you came from a domestic Chinese ROM, clean data for calender, notes, desktop and if possible contacts, using these utilities. Or if you do not mind, wipe all data from recovery.
=================
BTW: Due to new forum rules, resulting in a large number of people that cannot post into developer threads and that subsequently PM me, I open op a new Q&A thread.
I am not going to be policing, so you can post where you like, but I invite everyone to use this new thread for any Q&A, and this thread for ROM releases and deep development talk only.
Consequently, if you PM'ed me, look for your reply in this new thread
Thanks
====================
PS: do drop me a reply if you use or tried it! Or press the 'thanks' button.

HELP, I lost my IMEI ! / Caller ID
Please note the content below was originally in post#1. I cleanup Post#1 a little, to make it clearer to new users.
=================
Hi All
My second Lenovo A750 ROM release: A750_S148_120428_cybermaus_V1
Edit: For ICS rom check the 2nd post.
Fixed toward V0
- Different GAPPS, resulting in
- More stable Play Store with less unlisted apps
- WiFi based Location services (from for example Places) working (GPS did work in V0)
- NANP (US style) numbering formating removed from phone
- Replaced Unicom talking bootup animation with silent Lenove butterfly
- Added 'new phone Setup' program
Still to improve (if you know how, on a MT6573/MT6575, let me know!)
- Caller ID lookup in Contacts should ignore IDD prefixes
- SMS app trips over hyphens and brackets in stored numbers
- Arabic/Hebrew RTL fix not applied yet.
- Remove 'new phone Setup' program again?
This is a simple and clean ROM, not too much done, essentially just the factory S148 ROM (A750_S148_120428) rooted, cleansed from Chinese and with Google Play Store and other GAPPS.
So it is mostly clean. It does not even have the Skype/YouTube/Flash apps, as I believe such apps change too often to be in the system portion. I upload the ones I got from Etowalk separately, in folder Etotalk_apk, you can install yourself.
Specific changes:
- Rooted the phone
- Set to boot in US-english
- Added MoreLocale for extra languages
- Removed Chinese apps, incl Chinese keyboard
- Removed SmsReg.apk
- Left Lenovo Security (anti-malware) intact
- Added Google framework
- Added modded Play Store 3.x.16-mod from XDA
- Added MobileUncle toolbox V2.0.9
- Added CWMR Touch / 593zn.com recovery image
Most images are unmodified from stock S148, even boot.img is unmodified. Only system.img was really changed, you could flash only that.
You will also need the flash tool and USB driver. For example tool SP_Flash_tool_v3.1208.01 and driver USB_VCOM_Driver. The flashing is the
typical Mediatek MT6573/MT6575 based flashing sequence as shown by bgcngm, the undisputed champion of Mediatek ROMS.
Which reminds me: Thanks to bgcngm for his help, and to jazzor for his help
Instructions:
By default, the ROM will not overwrite USERDATA. If you want a clean slate, first extract empty.userdata.rar. Also do this if you get "weird" behaviour after flashing, like Play Store not starting, your old setting may be incompatible with the new ROM
By default, the ROM will not overwrite FAT (the internal SD card). If you like an empty internal SD card, extract empty.fat.rar before flashing.
By default, the ROM will clean out CACHE. If for some reason you feel CACHE should not be cleared, deselect the CACHE from flashing.
IMPORTANT: If you want to play it safe, it may be wise to backup your phone's IMEI file before you flash or reset to factory defaults. See here for help on backup or restoring IMEI
IMPORTANT: If you are trying this ROM on another model phone, which I STRONGLY advise AGAINST, then do NOT flash the first two (preloader and dsp_bl) as you will may not be able to flash it back afterward and thus brick your phone. Someone tried it against an ZP100 and bricked his phone.
Download A750_S148_120428_cybermaus_V1
I will also upload the driver, flash utility and official ROM's there.
Enjoy

------------------------------------
Caller ID bug
Caller ID on the on the A750, on the P700 ROW, and I suspect in general on the Lenovo phones.
The lenovo ROW (=Rest Of World) based ROM are much more international then the other Lenovo ROMs. I cannot be sure about the other china brands, but Lenovo in ROMs intended for the local China market, 'update' the phone to nicely recognise chinese cities. I am sure China locals will be pleased with this service. I do not know if/how this applies on phones which are already more international like the multilingual Zopo's and Thl's out there.
In doing so, Lenovo seems to break the normal caller ID function. Not only do you get to see Chinese city names for non-Chinese numbers, but also in some cases it does not resolve an incoming call to your phone book. This seem to be especially true if the incoming call is in local format (no +CC) and the phone book is in international format (with +CC)
The ROW based ROMs work much nicer. No Chinese city names for non Chinese numbers. Also, it finds correct country names. So far, I was called by unknown numbers from California, UK, London, Russia, Romania, Saudi, Yemen and Jordan, and it all correctly resolved them. For California and London even to greater detail then the country. It only shows this for unknown numbers, for known ones it shows the contact name.
Indeed Caller ID seems to work correctly for local vs international format. So if the incoming is formatted without +CC, but leading 0, and the phone book is +CC, it finds it.
And it seems to nicely format all phones according to the desired national formatting. So +1 XXX-XXX-XXXX for US, but +966 X XXX XXXX SA fixed and +966 XX XXX XXXX for SA mobile. And +31 XX XXXXXXX for NL fixed and +31 XXX XXXXXX for NL mobile.Very nice
HOWEVER: The caller-ID lookup now seems 'whitespace-sensitive'. I had a contact number stored as +966 XXX XXXXXX, and he did not find it. But when I changed it to +966 XX XXX XXXX it did find it. Similar for number that had "(XXX)" brackets in it, as was common in NL in the past.
This may or may not be a problem, because if you touch your phone book entry in the edit mode, it will automatically change +966 XXX XXXXXX to +966 XX XXX XXXX. Symilar if you sync through Google. But as I sync with outlook using Android-Sync, many are stored like +CC (XXX) XXXXXXX
So, Caller ID is 'different'. But better? For most people probably yes. But may depend on your situation.
EDIT: I found the whitespace was actually due to me not clearing data. Everything seemed find, but the caller ID was a resulting problem. You need to clear contacts, so it reindexes the phone numbers, and then Caller ID is perfect. Even ignores () brackets. You can clear contacts many ways, but I made a patch for it.

Links to other A750 ROMS and other useful information:
EDIT: I have not kept this list updated. Search this thread for other ROMS, especially Smileyvvv's APKHOT seems popular
Original A750 ROMs: (S14x=GB; S30x=ICS)
A750_S148_120428 - Chinese/English - No root - No play store
A750-S305-120514 - Chinese/English - No root - No play store
A750_S306_120530 Original full S306 (no OTA, flash package)
Please note that all *official* ROMs come with password bbs.lenovomobile.com. If the password is missing, someone did something to the ROM. Also, there are 'root' images availible that only flash boot.img. These work by overwriting system.img *on every restart*. Creative, and I used it myself for a while, but currently I feel the method described below is a better method.
Other modified ROMs (GB):
S750 S143 Etotalk Multilang
A750_S148_120428_RUS by Anton_vrn V1.3 (true Russian translation!)
BM's Hebrew fixed
BaderMQ's multilang+Arabic fix
(please note none of these are really multilang, just multi-locale, which means system apps will remain English, but third party apps can be set to other languages, similar to my ROM's, I simply do not make the claim. Anton is the only one who actually translated the ROM, but to only one new language)
Other modified ROMs (ICS)
My ROM in sepo of course
lenovo750-4.0.3_Anton_vrn_v3.01(true multilang?? Hints that it contains: ar-de-es-fa-fr-in-it-nl-pt-ru-th-tr-vi-zh, but based on S305)
Etotalk S306 multilang_by_Dean : It exists, but I do not know an internet location to download it from.
How to root a ROM yourself:
- Flash the CWMR Recovery partition (the recovery only, not the root&recovery one)
- Reboot into recovery (poweroff - Press/hold Power for 2 secs, then also Up/Down)
- Apply this root update
- Use RootExplorer to remove any Vending* or Phonesky* from /system/app
- Apply the correct GB or ICS GAPPS package, from bottom page here, or its mirror here.
- If a ICS rom, even though not from me, you may still want to apply my ICS V1.3 update, especially if you have location or market compatibility issues.

Caller ID
Hy I have a Lenovo A750 and all my contacts in the address book are saved in international format ex.: +44 78......, and when somebody calls me the number that shows up on the display is 0 78....., as local format.
Unfortunately the phone doesn't recognise it as being saved in my address book and it show's me "078 .... is calling" instead of "Ben is calling".
How could I fix this?
Please help me, or at least give me directions.
Thank you

Its one of the more important (of not most important) issues, and it has focus of myself and more experienced people. It's listed above as "Caller-ID to Contact mapping should ignore IDD prefixes." But alas, afaik, at this moment, no solution exists.
Keep an eye on this thread, and/or this one. Rest assured that as soon as we know how, it will be fixed.
Edit: Caller ID bug is less prominent in ICS ROM's
And in any case, using this, you can work around it.

COOL
You have done great job man thank you. I was using etotaks v 2.0 rom but it kind of sucked so i decided to try yours and its all good. I like the net traffic, battery saving and LeSecurity and they come only with the lenovos rom. I will look foreward for future releases. Great Job.
Reagards.

RTL
Hi,
Are you planning to update your rom?
i was searching for a Lenovo A750 rom that support Arabic - Hebrw RTL.
There is a methods out there but its only for deodex Roms,and your rom odex.
anyway to convert odex to deodex?
Thanks

There is already a Arabic & Hebrew RTL version for A750 out there. Not my me, but by someone more experienced, though A750 is not his focus.
I am playing with my ROM, and while it is not on the top of my list, once I get round to updating it I was thinking of copying his RTL fix to my ROM also. In the mean time, try the other one, and tell me how it works in relation to the issues I still have on the to-do list.
Thanks

I downloaded the rom from that topic , it failed to install . it give me an error msg when i try to flash it thru CWM.
I manage to convert the lenovo A750 Roms to odex using crcstudio_1.2.0.0
now i'll try to apply the fix manually.

Well, you can always try to use the recovery I am using. It seems to work well for Bruno's ROM's.
I have never even attempted to put CWM on these Mediatek based phones. Nor have I heard of anyone else (other than you). Are you able to flash anything with it? I was assuming there was a reason people were not using CWM on Mediatek.
I advise you to put Recovery ROM from here, flash it using this method. And then use that to apply the zip based ROM's.
I am working to update my ROM with Hebrew also (actually, working on other stuff, but will try to also put that in), but be aware, it will also be a 'flash-utility' ROM.
Edit: ROM V1 is coming tomorrow, but no RTL, sorry. I was able to fix the location service and Play Store is now not blocking so many apps.

I already did try CWMR ... But when i ever try to flash BM Rom it shows an error.
And by the way .. I already used CWM to flash other roms on my A750 and its working.
so what i did:
I extract BM Rom and merge it with other chinese rom S148 and build new rom.
It works.. i can read/write Arabic . and for browser/gmail i install the Brightidea's app from the market. it fix the Arabic problem.

New V1 upload in first post.

Spanish from etotalk?
There are any possibility to get the spanish traduction from the etotalk rom?
Thank you

I'm using new ROM since last night.
I made a complete flash (userdata, sd...).
Now there are less Chinese applications, is good.
Good work, Thank you.

Quick question
Hi cybermaus
sorry for the noobie question but I didn't own a smartphone since windows mobile. I expect a A750 and it might come unrooted. Do I have to root it before installing the rom or is this done automatically in the flushing process? Thank you.

Check if the Spanish selection is part of the 'MoreLocale2' app. If not already there, add it as a custom locale.
Edit: If you meant: can I take Etotalk ROM and transplant its Spanish into my ROM, then that is already done! Neither Etotalk nor myself actually translate anything, we both just added the free public app MoreLocale2, which has most translations in it. Using MoreLocale2, the phone becomes 'reasonably' translated, though there may remain some English parts.

This flash is using bootloader method, not recovery, and it will not need root. Upon flash, it will apply root automatically. Use the flash sequence as linked in the first post.

It is strange the size is only 157 mb. I will give it a try

Yes, V0 accidentally had two copies of the rom image inside the rar. It did not hurt, but it bloated the package a bit. The 157GB (164 981 710 bytes) is correct
Good to see you are paying attention though

Remove the Unicom bootup animation
I landed on this page when I was looking for help to remove the Unicom talking bootup animation/sound and remove all Chinese apps from my phone (A750) that I recently picked up.
But I have never done this and I am no developer but can you please help me with a list of procedure that I can follow to use this A750_S148_120428_cybermaus_V1?
If someone has skype or share their phone number I can call to seek help.

[RECOVERY] Clockworkmod Recovery for ZTE V967S

DISCLAIMER:
Rooting your phone and using custom Recoveries and ROMS have risks and may result in bricking your device, and has nothing to do with Google or the device manufacturers. In case of any mishap I am not responsible if you brick/ruin your phone in any way.
Basic computer skills are required and minimal knowledges about phones and phones utilities too.
Make sure that whatever you do, you are doing it at your own responsibility.
I built from source a CWM Recovery, version 6.0.4.4 adapted by me to build in cm-10.1 environment, for ZTE V967S phone. I have to say Thank you to C3C076 for his help. He was kind to help me to figure out how to tweak building source for recovery, to obtain a compatible recovery. So, you should thank him, or even better to donate to him if you can. Now I improved the MTK compatibility, I fixed restore old recovery issue.
The CWM 6.0.4.4 recovery can be downloaded from downloads section. If you care enough, and you like what I did, after download just hit the Thanks button. If you use it or port it and ask other to hit Thanks for you, do the same here to show respect for my work.​It is fully functional: it works for flash zip, to wipe, mount (both internal and external sdcard), backup, restore, format to factory from phone settings menu, apply updates from stock ROM, etc.​If you share my compiled recovery on other sites or forums, please give proper credits for it!

CREDITS and THANKS
C3C076 for his help on tweaking recovery source.
bgcngm for his wonderful tool for unpacking and repacking img.
rua1 for MTK Droid Root & Tools.
dsixda for his Android Kitchen.
Cyanogenmod Team for their wonderful project.
Koushik for creating Clockworkmod Recovery and for constant improvement of it.
-- You really should thank to all of these guys or if you can to donate to them, because without their hard and fine work, we couldn't enjoy our phones as we should.

If you choose to use these, you are doing that on your own risk, and I can not be held responsible for any damage you made to your phone.
1. SPFlashTool backup ROM
A SPFlashTool prepared backup from last stock version 1.0.0 - 27.08.2013 for NonChina Market, if you need to unbrick your phone, or if you want to revert to stock. This version has English as default, and also include Chinese and Russian. It has root and custom CWM, otherwise is untouched. You have to flash this one with SPFlashTools. The scatter file is included.
3. A version prepared from last LewaOS v5 - only English - LewaMax v2.
Rooted, optimized, gapps included. The ROM will not change your recovery.
INSTALL INSTRUCTION:
Many people have problems with force closed processes because they don't flash a new ROM properly.
- In recovery, mount USB Mass storage and delete from sdcard these folders:
.android_secure
Android
LOSTDIR
- then back in recovery do a wipe all data/factory reset in CWM or Pre-Flash wipe in COT
- in CWM in advanced menu wipe Dalvik cache / in COT in storage management menu wipe Dalvik cache
- Now flash the ROM zip.
ATTENTION:
For extending data partition please refer to this source. It's better than my previous modd and I think it's safer. Thank you meteos.But, I recommend you to use top 2.5 Gb data partition size, and let remaining 237 Mb for sdcard failure situations.​
Here you will find MTKDroidTools of rua1's.

1. A SPFlashTool prepared backup from last stock version 1.0.5, if you need to unbrick your phone, or if you want to revert to stock. It has only root, otherwise is untouched. I removed from that the preloader, since is a high risk to damage your phone using that. But if someone need it I will send him private. You have to flash this one with SPFlashTools. The scatter file is included.
2. An optimized ROM, prepared from 1.0.5 stock version, ZTE V967S ROM Max Flavour v-2. Slimed, odexed (about 60Mb apps on data usage), zipaligned, busybox, debloated, multilingual (sort of), and some other things. I replaced the Launcher with SOLOLauncher because is lighter (only 5-6 Mb instead of 20) and have more features. I've tested it and it works flawless. You should flash it with CWM Recovery.
3. Will come a version prepared from last LewaOS v5 for MIUI fans.

Hi Carliv, thank you very much for your rom. I am trying it and I am quite happy with that. I am only experiencing some problem with GPS: in some cases I was not able to switch on or switch off the GPS. Another thing that looks a little bit strange is that in YGPS -> Information the "chip version" is "UNKNOWN". With the sock ROM I am sure that the information about the chip version was displayed (MTK_GPS_.....). Have you the same issue?
Ciao.

No, I haven't any problem with GPS, and if you check GPS in YGPS with GPS switched ON it will show you chip version.
I don' understand where you can't swith on/off GPS: in quickpanel toggles, in settings locations... You don't say that. So, please, be more specific.
When I need GPS, I turn it ON, and it connects in about 3 sec. if I'm outside, or maybe 10 if I'm inside near a window.
Thanks for appreciations.
I'll try to help you if you give me more informations.
--------------------------later edit------------------
One other thing, I noticed that if you use scheduled power off/on, you have to manualy restart the phone after self turning on, because the WIFI and GPS doesn't work properly... I don't know why, and I think this is a bug in 1.0.5 version.

hello ,
thanks for your support in our phone ZTE V967S
i have bought the phone from minideal.net with 1.0.3 MULTILANGUAGE, rooted and google play store version and chinese CWM, but i want to install 1.0.5 version

i want to install SLIM version to have battery improvement but i am a little afraid if sth goes wrong (someone says that the GPS is not
working perfectly and maybe some important things are missing) what is your opinion for SLIM version in general? will i have a problem if i install SLIM
compared with FULL?
also i want the 5GB userdata partition.. how to manage that?

You're welcome!
Now, let's see:
1. No ROM is full multilanguage, except the case that all apps have multilanguage support. Otherwise, my version is as much multilanguage as minideal version from what I've seen - I ported translations from a Lenovo P770 because is very much similar. You will have Greek just like in minideal version.
We can try togheter to make a better translation if other users want that; I can post here archives with xml files that have to be translated, you make translations, post here back and I could integrate them in a ROM. That way we can translate even SystemUI, which now isn't.
2. To install CWM the easy way is with SPFlashTools - all you need is the scatter and recovery.img. Of course, you have to install proper drivers before - you can find them in first post. How to use SPFlashTools I can't reproduce here because there are several guides on forum, here is one of them. Just one thing: if you find hard to enter the phone in bootloader, just remove the battery and connect the phone to computer without battery - it will enter in bootloader automate.
3. I don't have gapps in my phone SLIM ROM, but version posted to download has, because many of you use them - I don't. The GPS is working perfect for me, the only bug I found untill now, and don't think is related to my work, but to original release, is that if you use Scheduled power on & off, after phone starts from sleep you have to reboot manualy, otherwise Wifi and GPS won't work correctly. I hope they'll solve that in a next release like they did with camera flash. But, overall slim or full version shares the same drivers, modules and libraries, and only difference is in installed apps. The full version has stock launcher and weather, and live wallpapers, etc. The slim version don't have those things.
4. You can't use a 5GB userdata partition because the entire phone memory is 4GB. You can expand userdata to max. 2.7GB, but I provided a solution for 2.5, because in case o SDCard failure on mount/unmount or other event, the phone will use those 270 MB from internal storage to function properly until you fix sdcard, without losing data. There are some solutions to expand data partition on sdcard, but I didn't tried them and I can't say you how that works. My ROM with 2.5 GB support will repartition userdata for you during install, and when the phone boots up you will see internal storage 2.5 GB instead of 1GB.
Ok, That covers all your concerns. Thank you for appreciations.

1. for Greek Language i think i am ok... as i can understand you import multilanguage support from Lenovo P770. how minideal managed to have Multilanguage support for 1.0.3 ?
did they import from another phone too?
2. another solution to install English CWM recovery is with Mobileuncle MTK Tools. do you agree? but thanks for your help for SPFlashTools.
ZTE USB Driver.zip ,MT6589 drivers.zip, MT6589 USB VCOM drivers.7z. which of the 3 drivers to install in order my PC to recognize my
phone? how to enter CWM? what do i need to press?
3. i want to have your SLIM version but with Google Play Store installed. how can i do this?
Are we sure that the problem with WIFI and GPS not working correctly after phone starts from sleep (Scheduled power on & off) is a problem
of ORIGINAL version? maybe it is sth eith your rom.... can someone confirm that?
4. what is the purpose of Extend2_5GBUserData.zip ???
before i had Xperia Sole . because the internal available memory for installed apps and games was about 4 GB some people developed a
tool to swap the internal memory with the external SD card. in this way if someone has 16 GB external SD card he/she can install BIG games without capacity problems

You're welcome!
Now, let's see:
1. No ROM is full multilanguage, except the case that all apps have multilanguage support. Otherwise, my version is as much multilanguage as minideal version from what I've seen - I ported translations from a Lenovo P770 because is very much similar. You will have Greek just like in minideal version.
We can try togheter to make a better translation if other users want that; I can post here archives with xml files that have to be translated, you make translations, post here back and I could integrate them in a ROM. That way we can translate even SystemUI, which now isn't.
2. To install CWM the easy way is with SPFlashTools - all you need is the scatter and recovery.img. Of course, you have to install proper drivers before - you can find them in first post. How to use SPFlashTools I can't reproduce here because there are several guides on forum, here is one of them. Just one thing: if you find hard to enter the phone in bootloader, just remove the battery and connect the phone to computer without battery - it will enter in bootloader automate.
3. I don't have gapps in my phone SLIM ROM, but version posted to download has, because many of you use them - I don't.

I don't know how minideal got their translation, maybe they did it, it's not that hard, there are 4 files to translate to every language, and other 2 if you want SystemUI too, but you have to know a lot of foreign languages. That's the reason I said we can make a better translation, but everyone have to translate from English to his language.
Yes, you can install recovery with MobileUncle but you have to be rooted and to have MobileUncle installed. The way I presented works even for untouched stock ROM. Don't matter which order you install drivers. Install them all one by one, and connect phone in normal boot and wait for windows to install previous drivers for the new device, then connect phone in bootloader and wait again for windows to install necesary drivers.
The slim version posted here is with gapps included, you don't have to do anything for that - I thought I made myself clear. The version without gapps I kept it for me, I didn't share it. Most people want gapps and there was no reason to upload a version without them. No, I don't think that refresh for GPS and wifi has anything to do with my intervention, it's related to the way the phone enter to sleep and wake up, because is not completely shut down. My guess is that on wake up, not all modules are started properly, and that's the reason a phone restart solve the problem: when Android starts all modules are loaded correctly.
The purpose of Extend2_5GBUserData.zip is, as I said in that post, that people who don't want to install any of my ROM with 2.5GB support, to achieve an extended partition while they keep their ROM: minideal, stock original, or others not shared by me.
I know about that thing with extend to sdcard, but I didn't tried yet, and from what I've seen compiling recovery, for this phone you need to unpack, repack recovery.img and boot.img too, to modify fstab, not only that from etc folder. So, it's a little bit more complicated. Some people made some scripts for that for this kind of phones but for different cpu. I can't help you with this matter, because I'm not interested in it. For me 2.5GB of internal memory is more than enough.
LewaOS v5 is a different framework, more like MIUI, but with different launcher type. I did a debloated version, because LewaOS is mainly for China, and they have a lot of chinese apps. The people that download it they know what is. I used to like it, but now, the ZTE ROM, optimized please me more.

thanks for your help. I am really appreciate this. so if I want to extend my internal storage to 2,5 GB directly to minideal modded rom version I need to flash Extend2_5GBUserData.zip via CWM. right? there is no need to install first your modded version.
how to connect my phone in bootlader mode???
so you propose me to install lite version. I will give a try when my phone come to my hands!!!
one more question maybe not suitable for this thread but I wll ask you. do you know to propose me good screen protectors and slim caces for ZTE V967s? I heard that V987 quad uses the same protectors and caces with V967s. is it true?

Ok.
I don't use any screen protector. The screen is Gorilla Glass and you can't scratch it even if you want. Actually I can't find that info now, I've read that ZTE support answer that to a user. On official description is an IPS screen. But seems to be very hard. I've tested it with door key, really :good:
And the case... Mine came with some sillicone cheep case, I don't like it. I don't know if the case from v987 fits, because I know that v987 is 0.7mm thinner.

so you have this phone and you bought it from minideal.net. right?
you make me happy. but I am not sure for Gorilla Glass. the specifications does not mention that. and Greek guys say that is normal glass not Gorilla. are you sure for that? if you use your nails it will not scratch the screen.
also you have not answered me for Extend2_5GBUserData.zip
can I flash it directly to minideal modded version or is it necessary to flash your rom first?
about a slim case fitted exactly to our phone do you have sth in your mind to buy ?
also how do you find the photo and video quality of the camera?
thanks for all. you are great

Ok, I modified that to official infos, IPS screen. I've read that in an email support answer from ZTE, but I can't find now the source.
About Extended 2.5 GB I already told you two times, you can use it with any ROM, or to be specific: you can flash it on your minideal ROM.

The same steps for those who want only to increase userdata partition, without installing any of my ROM. But you have to download Extend2_5GBUserData.zip from attachments....

I don't know any case because I don't use one, but I read somewhere, I don't remember where, about a leather case for it. I don't know more.
The camera is average, but I didn't expect much from it, I have a DSLR camera for photos.
Cheers.

sorry my friend. just wanted to be sure !!!! sorry if you repeat some things twice for me.
in what way do u extend the data size up to 2,5 gb ? is it dangerous for the phone or does it has any effect to the performance and speed of the phone?
about the screen I have read in the official specifications that it is IPS and not Gorilla glass.
but first as you said somewhere read that it is Gorilla. and secondly you tried with your nails and key to scratch the screen without damages. if the screnn was just IPS this would never happened. what to say?????
I am a little sad with the picture quality!!! never mind.

Well, the method for repartitioning is presented here by meteos. You just need to modify in hex editor some values for Extended Boot Records EBR1 and EBR2. It's not dangerous if you don't make mistakes and enter some values that extend userdata more than 2.7 GB, and that wipe some portion of primary partition. In that case you will have a bricked phone and you can repair it, only by reflashing entire ROM in SPFlashTool.
EBR is for logical partition (userdata, phone storage or internal sdcard) and MBR for primary partition (Boot, Recovery, System..).
My archives are safe, and I've tested both myself without any problem. I'm using now a slim ROM with 2.5GB userdata (internal memory).
You're welcome.

thanks for your help.
you are always helpfull.
if you have any news for new scripts which swap the internal memory with our external SD card memory just inform us..
did you try to play heavy games? does the phone play them smoothly?
if you increase the storage to 2,5 gb what do you choose in storage option : auto , sd or internal storage?
a greek friend of me tried your SLIM rom. he said it is very LIGHT and FAST. But he has problem to select GREEK keyboard. he selects greek keyboard but the choice can not be saved. please try to fix this!!!

Ok, sorry for late answer. I was busy to update recovery to 6.0.3.6 version.
Now, I don't have time to play games, I never installed one in my phone, so.. I don't know how they work in it.
The increased storage is for memory (if you install heavy apps which needs a lot of memory, they use that as virtual memory). I select always sdcard in storage options as default.
I don't know why your friend has trouble to set greek keyboard. I selected it, test it, reboot phone - still there. To select: Settings - Language & Input - KEYBOARD & INPUT METHODS - Android keyboard settings - select only languages you use and deselect others - go back - Default - select Greek - exit - done.
I know it's light and fast, I wanted to be.

Lenovo S8 A7600 [Official Rom] [Instructions]

Hello
Seeing there is very little info about this model, I decided to make available my findings. Initially I was a bit annoyed with the phone in the start. The "stock" rom was a disaster (malware-ridden, non-official). First I tried to de-bloat that but the whole rom was just bad and unstable. Since then I've learned some things, and newer official builds have surfaced.
Also I should say; this phone is basically a K3 Note with 720p screen (another difference is MT6752M cpu instead of MT6752 in the K3 Note) and it's very similar to the A7000 model.
The best rom I have tried so far is this : VIBEUI_V2.5_1532_5.1797.1_ST_A7600_CU ---> DL - This is latest official stock Rom for the 7600 (not 7600M which is Chinese version)
Here is also TWRP recovery with english + chinese language: DL
Rename ROM to "update.zip", use stock recovery and flash (probably best to use stock lenovo recovery first to make sure everything gets flashed, can be flashed with twrp but I suspect it only flashes boot and system), boot it up, finish the setup wizard, turn it off. Use SPflashtool to flash TWRP, turn off again.
Start phone in recovery mode (Press volume Up + Down, and power button. Hold until recovery appears). Now you can flash Gapps (arm64, lollipop 5.0, opengapps.org), SuperSU, xposed arm64 lollipop, etc.
I have been able to get a very pleasing phone doing this. I don't really feel right now that much is missing, and I'm not annoyed by various other problems. Using xposed modules gravity box, GEL settings, Lollipop memory fix, etc.
This Rom has very little bloatware, there are some chinese apps, but they can easily be uninstalled - don't even need root. There are a few more you can uninstall using root if you want, but be careful not to break the system.
I'm not going to explain everything in great detail here. Using SPFlashTool is explained so many other places. Getting supersu and xposed also explained everywhere.
If I could I would integrate all in to one flashable package, but I'm not a rom cooker. Sorry
PS: As you can see in the image, i use iFONT xposed. But I don't enable it as xposed module, that caused problems. I just used it to download a font and applied it. It's system wide, and it works
There's a newer link in post #6 with the latest firmware
There's a newer link in post #10 with TWRP 3.0.2.3

Hi,do you have custom rom for lenovo s8 a7600?

sorry, I had to remove your links, because I have small amount of posts and I am not allowed to submit post with urls - even if quoted.
Hi!
Do you know way to install other languages into ROM (or add them and somehow rebuild ROM), I am searching informations for last few days with no succes. The main problem is when international apps using EN for directory, when all information in directory should be in my language (polish). Changing locale helps, but settings are crashing with changed locales..
Also I installed xposed, but system tells me that xposed is not installed... I heard about it from your post and found only version v79 for sdk 21. I need to remove search box from desktop at google now.

Any custom rom for this device ?

Hi everyone, hi @askermk2000
I just received my Lenovo S8 A7600 "Golden Warrior" phone from an Asian vendor, it came with VIBEUI_V2.5_1524_5.1460.1_ST_A7600_CU and SuperSU was seemingly installed when I first turned on phone (asked me to update binary).
Specs are MTK6752M 64-bit OctaCore, 2GB RAM, 8GB storage.
Can I install your version VIBEUI_V2.5_1532_5.1797.1_ST_A7600_CU through the Lenovo stock recovery/flash (phone) as you suggest?
You mention "not 7600M" so I am not sure...
I also see in other places that there's even a newer VibeUI version VIBEUI_V2.5_1537_5.1978.1_ST_A7600_CU, any idea where to get it and if it is compatible? I cannot find any download link...
Thanks...

Hello
It's wise of you to remove that dubious vendor firmware.
Since "A7600M" is a model number, or simply name of the phone, I would be surprised if it doesn't say so anywhere. Look at the packaging, phone and battery compartment etc. If you don't see A7600M anywhere, it's likely not that model.
See here: Lenovo Inquiry Page
At the bottom there you'll find link for the latest official (Full) firmware.

Thank you @askermk2000 for your kind and immediate reply.
This known asian vendor on their page mentions: Lenovo "Golden Warrior" S8 A7600, 4G, LTE, MTK6752M @1.5GHz 64bit OctaCore, 2GB RAM, 8GB storage, 5.5inch HD IPS screen, OTG, Android 5.0 Phone
In settings, the ROM version is: VIBEUI_V2.5_1524_5.1460.1_ST_A7600_CU, no bloatware; was surprised to see SuperSU pre-installed but the vendor does have a service (at a cost) to provide pre-rooted phones (which I did NOT order but maybe got).
The (Lenovo) box doesn't mention much, even under the phone I can see a lot of Chinese, so it's definitely for China -- vendor wrote it's unlocked for world use on their page.
The mentioned model is A7600 on the rear, there's only a A838 reference besides model (i.e. QQ-A838-xxxxxx) but not much more than that.
I suspect these may be older stock they wanted to get rid of.
As you can see, the model is (S8) A7600, not A7600M. The chipset has "M" i.e. is MTK6752M.
So can I not use the official latest (full) firmware that you posted, via stock recovery?
Is this not for MTK6752M processor? Will this firmware brick the phone, you think?
Thank you very much in advance!

No, your phone is the right model, as you said "Unlocked for world use", the A7600M only works in china.
MTK6752M is the chipset used - it has nothing to do with A7600M, that there are two M's there is a coincidence.
So you can go ahead and use the latest firmware.

OK for the sake of information to everyone, I did the following:
0. Formatted SD card from within the phone (just to be sure). Then charged battery fully to 100%.
1. Copy (via PC) the latest firmware zip file (currently is VIBEUI_V2.5_1628_5.2186.1_ST_A7600_CU_WC5DAF1811.zip about 1GB size) to root of my SD card. This file looks like a recovery type, but files inside (some IMG, DAT and scatter files) could be flashable from PC (i.e. like SP Flash Tool etc.).
2. Renamed it update.zip
3. Put SD and battery back to phone.
4. Started phone in recovery mode: Pressed Volume Up + Down and Power buttons simultaneously; held them until recovery screen appeared. First, Lenovo logo, then a screen to choose language (Chinese/English); pressed English.
5. Selected the Install Upgrade Pack menu and pressed "YES" to the warning about encrypted phones.
6. Waited for update with circle-type update progress; for some reason it got seemingly stuck at 75% for some period. Waited patiently to finish.
7. I selected "Back" to go and clean user data.
8. Once done, I pressed back touch-button and selected "Restart".
9. Waited to see what happens. Was curiously greeted with a white chinese splash-screen saying "4G" something. Waited...
10. Phone next booted to the usual Lenovo logo, with some chinese text at the bottom and three dots [...] flashing with thin white progress-line (most likely "rebuilding apps"?). This took a while, too.
11. The phone finally went into the wizard in Chinese, and then offered choice of English or Chinese as wizard language.
Wizard finished OK, then went to Settings -> About device -> ROM is upgraded indeed to VibeUI v2.5-1628 and Android 5.0.2.
NOTE: There's a LOT of chinese stuff, unfortunately, I guess it's part of the ROM; obviously this ROM is non-rooted...
However, the asian vendor installed/shipped ROM (VIBEUI_V2.5_1524_5.1460.1_ST_A7600_CU) was very light and fast -- I guess a deodex version? Or a VibeUI port?
Many thanks @askermk2000 for your help nevertheless.
Any idea, compared to your experience., if...
a) if your URL for latest firmware is maybe only for China? Your first post photos/screenshots don't have such Chinese apps On this ROM version, the shutdown logo is again that white chinese splash-screen with a big red "4G". Perhaps there's some other version for non-Chinese region?
b) if there's a stock, deodex ROM like that one? How did the Asian vendor find such light ROM, I am curious -- in that shipped ROM version, I had many menu languages. Now I only have English and Chinese as choices
c) if I need TWRP so I can flash Play Store, gapps and SuperSU? I don't think stock Recovery allows for these, any idea?
Cheers mate.

OK for the sake of information to everyone, I did the following:
0. Formatted SD card from within the phone (just to be sure). Then charged battery fully to 100%.
1. Copy (via PC) the latest firmware zip file (currently is VIBEUI_V2.5_1628_5.2186.1_ST_A7600_CU_WC5DAF1811.zip about 1GB size) to root of my SD card. This file looks like a recovery type, but files inside (some IMG, DAT and scatter files) could be flashable from PC (i.e. like SP Flash Tool etc.).
2. Renamed it update.zip
3. Put SD and battery back to phone.
4. Started phone in recovery mode: Pressed Volume Up + Down and Power buttons simultaneously; held them until recovery screen appeared. First, Lenovo logo, then a screen to choose language (Chinese/English); pressed English.
5. Selected the Install Upgrade Pack menu and pressed "YES" to the warning about encrypted phones.
6. Waited for update with circle-type update progress; for some reason it got seemingly stuck at 75% for some period. Waited patiently to finish.
7. I selected "Back" to go and clean user data.
8. Once done, I pressed back touch-button and selected "Restart".
9. Waited to see what happens. Was curiously greeted with a white chinese splash-screen saying "4G" something. Waited...
10. Phone next booted to the usual Lenovo logo, with some chinese text at the bottom and three dots [...] flashing with thin white progress-line (most likely "rebuilding apps"?). This took a while, too.
11. The phone finally went into the wizard in Chinese, and then offered choice of English or Chinese as wizard language.
Wizard finishedOK, then went to Settings -> About device -> ROM is upgraded indeed to VibeUI v2.5-1628 and Android 5.0.2.

Hello again
Yes, the official Chinese rom only has Eng/Chinese language. There may be a way to add more, idk because I only need English. The 4G boot logo is normal, was there on the rom linked in the first post also.
All the Chinese apps (or almost all) can be uninstalled without root permission. I never experience the rom to be less than fast and good, but I always immediately uninstalled the chinese apps, they do me no good anyways.
The rom you where supplied with is what is called ROW (international). If it's possible to get an updated ROW rom idk. All I know is that if you want a clean unhampered ROM, then the one I've shown you is the way to go.
PS: Yes you need custom recovery to flash the other stuff. Here is an updated TWRP: TWRP-3.0.2.3
^^This recovery has wrong device description in build.prop (actually it uses Lenovo K3) as a consequence you will receive error if trying to flash ROM's. So try the old one if you get these errors.

HI everyone, hi @askermk2000 and many many thanks for sharing your TWRP version 3.0.2.3 with us.
I followed this thread on how to root the Lenovo S8 A7600 phone and downloaded the tools needed (SP Flash Tool v5.1452.00 and VCOM drivers) on my Windows 7 laptop; then, installed them accordingly. Many thanks to @XxpikaachuuxX for providing links and steps on his thread!
1. Started up SP Flash Tool with administrator rights.
2. Chose the scatter file that was inside your shared TWRP-3.0.2.3 zip file; recovery image is automatically selected.
3. Shut down phone, remove battery.
4. Made sure all boxes in list were unchecked, except "recovery" then pressed "Download" button.
5 . Plugged phone on USB cable to PC, then inserted battery under the phone, as instructed.
6. Windows made a "USB plugged" sound, then SP Flash Tool detected phone OK and flashed recovery fine (there was the green tick-mark shown!)
7. Removed cable, removed battery, waited 10 seconds, re-inserted battery.
Then, copied to my SD card root folder, via PC (card reader) the following:
a) UPDATE-SuperSU-v2.46.zip
b) gapps-lp-20150211-signed.zip from this thread (lp=Lollipop)
(I had downloaded and installed wrong Gapps for 5.1 Android, but we need 5.0 version for this ROM--silly me. I just re-flashed via TWRP the correct package).
Went into recovery by pressing briefly Power then when the short vibration was felt, pressed VOL+ and VOL- and POWER simultaneously; the pleasant splash-screen of TWRP was shown!
1. Installed the needed SuperSU; then went back.
2. Installed gapps.
3. Wiped cache and Davlik (inside TWRP) then rebooted phone i.e. "system".
4. Waited patiently as it took a few minutes to go on the main Home screen.
5. Created Google account in "Settings" then went straight to "PlayStore" to update all applications, including SuperSU.
6. Ran SuperSU and upon request, updated the binary "normally" and rebooted just fine.
NOTE: In the Wi-Fi detected lists, since my first ever boot of this phone, I get a (fake?) SSID entry "NVRAM WARNING: Err = 0x10" which is apparently easily fixed for other phones. Do you guys you also got that?
A bunch of final questions to you, @askermk2000 when you have time to reply.
1) Does the stock weather display on a Home page work for you? I only get Chinese cities, location doesn't work as it says "city not found". Manual input of e.g. Europe cities doesn't show results, either.
2) Despite removing most via "Settings -> App Manager", any suggestions oh how to remove some further chinese apps that are marked "system app"? This article suggests NoBloat Free, Titanium Backup, System App Remover and App Master. I am not familiar with this approach but for example, "LenovoStore" could be removed...
3) Do you have by any chance the original, black b/g, folding (yes, boring) Lenovo animation boot logo to share? I see there's a file logo.bin for SP Flash Tools but others talk about /system/media/bootanimation.zip file... I ask if you have it, as the "Boot Animations" PlayStore app may not have the stock Lenovo boot. Perhaps flashing it via SP Flash Tool is better?
4) Will you kindly share any updates here to TWRP versions, whenever released? Do you anticipate any update in the coming 1-2 months, for example? (not sure there are bugs in TWRP-3.0.2.3, if any)
5) If there is a newer Lenovo official ROM available (than today) we obviously lose the TWRP recovery if we flash it all via SP Flash Tools; but we keep TWRP recovery if we update to the new ROM via TWRP, correct?
Thank you.

About that Wi-Fi problem. No I don't have it, and I was reading that page with the fix. It seems it's caused by using wrong settings in SPFlashtool, so likely the vendor did this when applying his trash firmware.
If you wifi is not working (as some reported in that thread) I would of course try to get a refund.
Weather gadget only has Chinese cities, yes I noticed that so I was using yahoo weather instead on my phone.
I would suggest Titanium Backup, it's what I use.
No, sorry I don't have any boot logos or animations.
This phone is a bit slow on the updates. But if there's an update, you can do it through the OTA update function which only downloads the changes as a patch. Though If your phone is heavily modified it might not work correctly. Could try a factory reset first, or simply start a fresh.
Then you would probably need to download the original recovery and flash that first.
PS: You can break the system by removing too much of the lenovo stuff. Remember VibeUi is heavily integrated and impossible to remove completely. Also, for gapps go to www.opengapps.org

Thanks.

[ROM][6.0][STOCK]{UPDATED} Lenovo Tab 3 8"/TB3-850F

STOCK ANDROID 6.0 MARSHMALLOW ROM
FOR THE LENOVO TAB 3 8"/TB3-850F
TWRP FLASHABLE ZIP
FORCE ENCRYPTION & DM-VERITY DISABLED​
DISCLAIMER: Your warranty will be voided by installing this ROM, unlocking your bootloader, or flashing a custom recovery. You hereby assume sole responsibility for any positive or negative consequences incurred by flashing this ROM. As always, flashing your Android device or otherwise altering its file system & partitions involves an inherent risk. I am not responsible for any devices which are bricked or otherwise rendered inoperable as a result of flashing this ROM. However, in such scenarios,
I will provide all support feasibly possible. Follow the simple instructions carefully and you should experience no adverse affects.
Lenovo's open source code for this ROM encompasses both the 850F & 850M variants of this tablet. Therefore, this ROM should be completely compatible with the TB3-850M as well.
NOTES:
This Stock Android 6.0 ROM is virtually unmodified. However, it should be noted that dm-verity (device mapping) and force encryption have been disabled via patched boot image. This is the most current stock OS for the Lenovo Tab 3 8"; therefore, no OTAs will need to be installed subsequent to flashing this ROM. In order to ensure that force encryption gets disabled, it is imperative that the /userdata (Data) partition is formatted in TWRP prior to Installation. Please carefully follow the below instructions.
For those members who want a pure stock experience, but also want root access of the stock OS, I'm currently compiling a deodexed & zipaligned version of this ROM, fully rooted with Magisk 14.0 & BusyBox binaries pre-installed.
SPECIFICATIONS:
Android Version: 6.0 Marshmallow
Build No: TB3-850F_S100031_171010_ROW
Kernel Version: 3.18.19
SDK Version: 23
Software Version: TB3-850F_160412
Build ID: MRA58K
Android Security Patch Level: 9/05/2017
Runtime Version: ART 2.1.0
Hardware Version: LenovoPad TB3-850F
Board Platform: MediaTek MT6735M
CPU: 64-Bit, Quad-Core Cortex A-53 - 1.0GHz
GPU: Mali T720 - 450MHz
RAM: 1GB
OS Build Date: 10/10/2017
Source Code: http://pcsupport.lenovo.com/us/en/products/tablets/a-series/tab3-8/downloads/ds112711
REQUIREMENTS:
1. Unlocked bootloader;
2. TWRP recovery;
This is a pure stock, unmodified, TWRP flashable Android 6.0 Marshmallow ROM for the Lenovo Tab 3 8". This ROM was compiled from the most recent stock /boot and /system images. However, as noted previously, the boot image has been unpacked, patched, and repacked in order to disable dm-verity and force encryption. Because raw firmware images were used in compiling this ROM, the file size is in excess of 1GB (approximately 1.35GB).
INSTRUCTIONS:
1. Download the ROM from the link provided and save it to your external micro SD card. Do not save to internal storage, as your /data partition will need to be formatted prior to installation;
2. Boot your tablet into TWRP recovery;
3. Wipe /system, /data, /cache & /Dalvik-ART cache. Also, select "Wipe", then "Format Data." This step is crucial to ensure disabling of force encryption. Please note that once installed, you may go to SETTINGS>>SECURITY and opt to encrypt the userdata on the tablet;
4. Select INSTALL, navigate to the location in which you saved the ROM zip file, and initiate installation. Flashing will complete in approximately 3 - 4 minutes;
5. Reboot system.
You should now have unmodified stock Android 6.0 installed on your Tab 3, as well as disabled dm-verity and disabled force encryption.

BUGS: Please report any and all bugs, no matter how seemingly trivial or insignificant. For those members with the knowledge, please submit a proper bug report. If you are not sure how, simply provide as many facts & details as possible. If you are having problems with apps, please specify as to whether the app is from Google Play. Also, please DO NOT submit bug reports unless you are utilizing this ROM in its present form -- unmodified, pure stock. Custom kernels, mods & tweaks (e.g. Xposed framework) & any deviations from pure stock will make it futile to analyze bug reports. Instead, provide with detail the precise nature of the problem. If reporting a bug, please specify if you are rooted (systemless or system-mode) and/or have BusyBox binaries installed. Submit screenshots of bugs if possible.

Brilliant! Will download now and report back later. Thank you.

My custom ROM for this tablet should be coming out of the Android Kitchen later this evening. I've dubbed it Ethereal OS v1.1 [Android 6.0.1]. Extremely lightweight yet moderately feature packed.

Nice!
After flashing the stock zip TWRP says unknown error. It booted up fine to where you login to your gmail and "bluetooth sharing has stopped working" pops up. Bluetooth can not be turned on within settings. I can not double swipe down to get to the notifications and the "Home" and "Recents" buttons do not seem to work although they both vibrate when pressed.
I will flash stock with SPFT and try your stock rom again.

I got the same error with Bluetooth Share force closing two times at the setup screen. Probably a corruption issue during archiving the ROM. I'll do an md5 and archive the ROM again.

Seemed to work, however the loading images and screen is still lenovo. Also they lenovo apps are still there.

This is not a custom ROM. This is pure stock. The Lenovo boot logo, boot animation & apps are supposed to be there. Like the title implies this an "Unmodified" stock ROM.

My bad, understood.
On another note, I am finding it very buggy. The home and overview buttons do not work. They show you clicked it along with the haptic feedback, but nothing happens. The back button works and is the only way I know to get back to the home screen.
Also the tool panel you pull from the top stops working after a little while until I reboot. Then works for a little while.
The Play store downloads barely work. They show pending and nothing happens. I force quite, cleared the cache, disabled, reverted to the stock app and it works for a little bit. Then the other Play Store app comes back. Anyways, I am not complaining. I appreciate the work you put into this. It's awesome we get to do it at all. Just giving my feedback. P.S. It's a new TB3-850F.

Yes. Very buggy indeed. I have determined that the bugs are due to corruption during the unpacking of the system image. I'm repacking the ROM now to alleviate the bugs. Thanks for your input...

I've managed to fix the major bugs reported upon initial install of the ROM -- Recents & Home Buttons, Quick Pulldown Menu, Google Framework bugs, New App Shortcut bugs, etc. Simply corruption during packing (archiving) the ROM zip. I will try my best to get a new build posted sometime today.

Did you get around to uploading it? I am unable to use the OTA update file. Says its missing 'android-info.txt'
Also, anyone care to point me to a way to get back to stock/unrooted?? Nooooo, I didn't backup my ROM first. That would have made way to much sense.

I've been out of commission, unfortunately, due to impending health issues once again. I know that hospital food sucks, that the pretty nurses don't typically put out easy, and that the hospital WiFi restrictions can easily be bypassed with a proxy server address. Lol. And that's all I've learned in the past ten days. Anyway, hope to be back in my daily routine in the next day or so and finishing some stuff up for this device.

Hi, is this thread alive? I'm interested in solution because i have about 60 tablets and need a solution to clone form one source tablet (config, apps, wlan, users, etc.) to other 59. I have tried adb backup --twrp and it went ok, but when i tried restore it gave errors with system partition and now i can only recover tablet with factory ROM from this thread (but it is buggy and cannot put it int to production like this). Is it possible to create system rom from other working tablet? Iwill be very pleased If You can write step by step, how to create zipped rom from working device so i can then upload it to share with others.

The thread is alive and I'm currently ironing out the errors on the posted ROM. The errors are due to a couple of permissions which are omitted on my updater-script file. I'll be posting an updated and hopefully error free release this week. Thanks for your interest and sorry for the delay in development. I've had a number of health issues of late and I'm now recovering.

Problem after wiping /system
Hi,
I´m new right here. I bought a new TB3-850F and wanted to flash the Original Stock Rom. After opening the Bootloader and booting into twrp like this way https://forum.xda-developers.com/android/general/guide-lenovo-tab3-8-tb3-850f-t3559786 I wiped the /data /System /dalvic and /Cache. After that I rebooted the system.
But it only shows after starting the Lenovo-Logo. No more booting. Because of this I can´t start the fastboot modus with Minimal ADB and Fastboot.
Is there some idea how I can boot into fastboot?
Many thanks for your help,

I´ve got a solution: After powering down, press power, wait 1 sec then hold both vol up & down also (all 3 Buttons) until vibrates. After starting in recovery Modus hold power button und press once the vol up.

Ok. I've debugged the Stock 6.0 ROM in the OP. Fixed the Bluetooth force close issue at startup and the bugs involving the hardware buttons and the pull down menu. I'm traveling for work at the moment. Soon as I'm back home Monday I'll post the fixed build in the OP.

Cheers buddy. Good stuff ??

@Hemphiz, I hope all is well my friend. Something I wanted to get your input on. It seems that a few members have been experiencing boot loops and other problems after following the TWRP & Root thread I revised. I'm sort of at a brick wall in terms of figuring out what's going on. I'm thinking that maybe there are regional variants that are incompatible with the TWRP we use. Or, it could be one of those situations where instructions are not being closely followed. What are your thoughts? Thanks.

[ROM][7.1.2][UNOFFICIAL][PORT] Resurrection Remix 5.8.5 for Lenovo A7600-F [MT6582]

Hello A7600-F Tablet owners, It's been awhile since there has been an updated ROM for this tablet. I have released ported ROMs for this tablet before, however they all had some annoying bugs and many of you reported issues with corrupted SD card partitions. The goal of this ROM is to provide as close to daily driver material for this old tablet as possible.
What better ROM than Resurrection Remix to do the job! :good:
Instructions:
Follow carefully! This process involves going back to STOCK firmware FIRST! This is to ensure your Internal storage gets properly formatted.
SAVE YOUR PERSONAL DATA! (Some where other than your tablet) You will lose it when flashing stock firmware. Don't worry about the struggles of getting ROOT on stock firmware, I have expedited the process greatly.
STEP 1: Get back to stock firmware. THIS STEP ERASES EVERYTHING, so save your data!!! Don't skip this step.
- Get any stock firmware file from here and follow the tutorial also in this link!
- The SP-Flash tool and drivers are all conveniently included with the firmware download.​- Don't worry about taking the battery out when the tutorial says to.​- If you have issues with the driver provided in the download, try these. (Run dpinst.exe)​ - Once completed boot into the new firmware just to ensure that you were successful. (Don't worry about going through initial setup we don't need it)
STEP 2: Install TWRP without root. You should now have a stock A7600-F Tablet, lets put TWRP back on.
- We will install TWRP with the same SP-Flash tool so that root is not required.
- Download the SP-Flashable TWRP image and scatter file from here.
- Follow the instructions in the tutorial linked in step 1 again but use the extracted TWRP scatter file you just downloaded instead of the stock firmware scatter file.
- You should only see "RECOVERY" listed in SP Flash Tool instead of all the stock partitions like last time​ - Once complete unplug the USB and use Vol-UP and Power buttons to get into TWRP
STEP 3: Wiping Instructions. THIS IS IMPORTANT! You should have TWRP installed and running at this point.
- DO NOT WIPE INTERNAL STORAGE! Doing so will cause the Corrupt SD-Card errors!
- Just don't do it! There is never any need to wipe internal storage on most devices.
- Go to Wipe -> Advanced Wipe
- Select only: Dalvik/Art Cache, System, Cache, and Data
- Wipe it.
STEP 4: Installing RR 7.1.2. You should now have an A7600-F with the stock partitions restored, and no ROM installed, sitting in the TWRP main menu.
- ROM Download: here
- GAPPS Download: here (Select Arm, 7.1, and whatever size you want)
- Now simply flash the ROM ZIP followed by the Gapps ZIP.
Reboot and Enjoy!
Things I improved over previous ROM PORTS:
- Better Audio quality
- Smoother Substratum OMS Support
- Camera Fixes
- FM Radio (Headphones only)

Just yesterday I've dusted off this tablet, and so I was browsing the forums to see what rom I can put inside, and lickily, about the same time this thread was created! Installing it right now, gonna post a follow-up once I'm finished tinkering with it.

OK, firstly wanna thank you for this awesome rom, it's stable and fast, no major issue with it. What I did find, however, is that the camera flash is not working along with the night mode which is not turning on. Besides those two issues, everything seems to be in working order
Cheers!

Thanks for the report.
Camera flash? My A7600 Does not have a flash. No actual LED to produce a flash.
As for the Night mode, I have ported a lot of ROMS to this device and I havn't ever seen the night mode work right. If I even do get it to turn on, it lags the whole device.

Haha, I've turned the damn thing over, looked at the sensor, and you're right. Havent actually used this device previously to know about it, so glad we have that one sorted out!

Thanks SaberShip. The ROM works great for general use and apps but I'm having an issue downloading files. It says SD card not found Download to default folder. I attempt to download to Downloads folder where it says I have 10.43gb stroage available but it keeps telling me SD card not found. I don't use an SD card for storage on the device. Do I need to use one or can you offer any other advice? I've carefully gone through above installation steps 3 times.

So I put in an sd card and I then had option to save to downloads or sd. I still could not select downloads but I could select sd card which is worrying for me now. Thanks again Sabership. Nice work

What app are you using? I have not seen any issues with downloading yet. If you see 10.43Gb it sounds like your internal storage is formatted correctly. I haven't seen any download issues with Firefox and ES-File Explorer.

Unable to flash firmware - because unable to install Android USB driver on Windows 10
Thank you for the new firmware. However, the instructions to install the Android USB driver in smartphone flash tool (link below) the link below does not work.. There is a signature error and everyone (as per youtube video comments) is having same problem.

Main post updated with signed drivers. Please try it now.

Thank you @SaberShip!
The installation of Resurrection Remix 5.8.5 was successful after installing the signed Android USB driver!. System is stable and fast. Thank you again.
App issues:
1. Netflix app (not available on playstore, but at netflix web site) works online, but does not allow video downloads.
Netflix diagnostic error for download is OF.NA.4 -which probably means device does not meet security requirements. ? any workarounds?
// Amazon Prime video works, with offline video downloads as well. Google chrome works. Tried other apps as well.
Documentation issues (minor):
1. "- GAPPS Download: here (Select Arm, 7.1, and whatever size you want)" --> Google Apps Super package did not install since the device ran out of space (error 70). Google Apps "Nano" worked.
System issues:
1. Wifi still does not auto-reconnect after Wireless Access Point is rebooted, but given that this has happened with different ROMs I am concluding it is due to a hardware issue with this device (and not ROM specific).
// Skype camera issue fixed. Camera image is NO longer upside down.

Netflix app not working on ROM due to Widevine DRM
Great job on the ROM!! - it is fast and stable.
I have been investigating why the <latest> Netflix app with offline download capability does not work with Resurrection Remix 5.85 ROM.
I found that some other ROM has similar problem, and it was caused because Widevine DRM was not supported. Netfix (latest app and offline download) started working after Widevine DRM support was added to that ROM.
Is it possible to support Widevine DRM in this ROM?
Here is the quote from another ROM:

I think it's connected to the files in the screenshot below, but I didn't manage to find a solution. I believe it must be implemented by someone directly in the rom code (I'm absolutely not an expert). I'm also sure it's not connected with root or anything else (the Netflix app is available in the play store for me).

Hello A7600-F Tablet owners, It's been awhile since there has been an updated ROM for this tablet. I have released ported ROMs for this tablet before, however they all had some annoying bugs and many of you reported issues with corrupted SD card partitions. The goal of this ROM is to provide as close to daily driver material for this old tablet as possible.
What better ROM than Resurrection Remix to do the job! :good:

SaberShip, thank you for all your work and caring about the A7600-F! Your instructions are clean and elegant. It's great to be able to install your ROM without root. It looks and performs great.
I installed your ROM a week ago. Unfortunately, I've spent much time since then trying to get NordVPN to work. It worked fine on the stock version of my tablet. Now, it connects to NordVPN servers, but fails to adopt the remote IP address (whatismyv6.com reports my ISP IP).
I've exhausted [email protected] I'd be grateful for any pointers you might have.

Hello,
so i will thank Sabership, too, for his new build. I went the way as most builds are normally flashed - reboot from AIM build into TWRP, did a factory reset, and flashed RR and a new GApps build. Everything went fine, i am just typing on it. The bug with WiFi not connecting automatically i am hoping will be gone, it was the only bug i found in AIM for me.
One question: the security patch date is of November 2017. Will there be an update (as asked in AIM, too)?
Regards

I believe VPN connectivity may have been one of the issues with the original ROM even before I ported it to the A7600F. Therefore, there isn't much I can do unfortunately.
If you absolutely need VPN, your options are to use Stock ROM or find a different ROM that has VPN working. Another possible workaround is to setup NordVPN on your router or whatever gateway is between you and the internet: https://support.nordvpn.com/Connectivity/Router/1047409322/Setting-up-a-router-with-NordVPN.htm

I have witnessed wifi disconnection issues on every ROM I've ever ported/used for this device aside from Stock I wish there was more that I could do. As mentioned in the title and before, this ROM is ported from another device. What this means is that I don't have the source code and therefore cannot update things like Android security patch dates. If this were a ROM built from source, I would simply have to sync with updated RR sources to get the new patches and RR bugfixes/features. To do it with a port, I need to find a whole new ROM with the updated sources and then port the whole ROM over to this device again. That is just too much work.
As a side note, I had intended this to be the last ROM I ported for this device due to its age, however If there is enough demand and I can find one, maybe someday I will port a more updated Oreo ROM to this device. Good quality MT6582 Oreo ROMs built from source are still not really common.

Thanks for your answer. If only i could do something like that of my own... i have so much interests, i don't know if i could learn that in a usefull time!
By the way, why did you call it "old"? i'm using the Galaxy S2 build 2011, with LineageOS 16. I think this is an old device , like my Galaxy Tab 1 and 2.
But anyway, thanks for your work. After some time i'll write again about issues i found, if it will be helpful.
Regards

Thank you, SaberShip. It's been on my list to get a DD-WRT enabled router, so maybe now's the time.
I've had no problems with WiFi.
If you build an updated Oreo ROM, I volunteer to test it. I'm fond of my A7600-F.

Just tested, It works perfectly with my USB wireless Keyboard and mouse combo.
When I tried a USB flash drive it did not mount automatically, however "SDA" does appear in the /dev/block/ directory so you can likely mount the flash storage manually with some terminal commands. YMMV

USB OTG works with both my wired and wireless trackballs (Logitech).
I mount/unmount flash drives with StickMount and explore them with Total Commander.

excellent. Works very well
