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

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.

------------------------------------
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.

Q&A for [4.4.4] MIUIv5 [Falcon]

Placing your question within this thread will increase its chances of being answered by a member of the community or by the developer. Thanks for understanding and for helping to keep XDA neat and tidy! :smile:
Xt1033 - miui-v5
Hello folks,
I have used MIUI before and it was simply irresistible to try it out on my XT1033. I was happily running Mokee on it after unlocking, rooting, etc. However, the device was still a 2-SIM variant. I converted it into GPE which worked with no flaws whatsoever. Please note that the xda-developers' guide (or package) didn't quite work for me and I had better luck with this guide.
Having my XT1033 converted to XT1032 (is it really a true conversion?), the following is noted:
System Version: 174.44.9.falcon_umts.Retail.en.GB
Baseband: MSM8626BP_1032.340.63.00R
Kernel: [email protected] # 1
Build No: KLB20.9-1.10-1.9
Android: 4.4.2
Next, booted into TWRP and wiped Dalvik, Cache, Data, System and formatted System (did all these twice to be safe).
Installed the MIUI.V5, which booted like a charm and was thrilled to find 3G Network immediately.
Next, I sent a USSD *123# to check my balance and it came back with a successful output.
However, (the pain starts now), when I tried to call someone the device threw an error ""Unfortunately, the proccess com.android.phone has stopped." The error returns at least 4 times after clicking the "OK" and finally disappears. It recurs if I try to call again.
I checked with the messaging app next, and alas "Message not sent" error increased my despair. I have followed all guides to clear cache, force-close contacts, contacts storage, dialer, etc etc and every last solution that Google could yield.
Lastly, and this ought to have come at the beginning:
Thank you for the wonderful ROM @Tqr, your hard work is appreciated.
XT1033
>This file (telephony-msim.jar) has been modified and might make dual sim working.
Nope. Didn't help. Still No SIM
Hello, i can't find a french translated rom, i've found this link :
https://github.com/ingbrzy/ma-xml-5.0-FRENCH
but i don't know what i'm supposed to do with it.
And, is there a way to hide the navigation bar (expanded desktop) ? And will OTA updates be available ? I don't know MIUI very well
How can i translate MIUI rom? i need spanish :/ can someone tell me? contact me at [email protected], give me the files where i can do manual translations and will upload them here :/ i can help to translate MIUI to spanish
Same problem here

M also facing the same problem phone and sms app does not work (force close) and after this network goes down. Did you find any solution? plz share if so.
Download link https://download.lineageos.org/osprey
There is a need to maintain list of stuff not working in the nightlies, since some people have Osprey as their primary phone
The purpose of this post is for easy access to a list of bugs by both the developers and the end user
Feel free to add to the post
-mention the ROM version
-the bug
-and any other relevant information
List
version lineage-14.1-20170125-nightly
Bug : Cellular Data doesn't work after disconnecting from Wifi
Temporary Solution : Developer Options -> Cellular data always active
Bug : When music is played through headphones and charger is connected/disconnected sound is played via both the headphones and speakers. Also happens for Shutter Sound
Bug : Random Bluetooth Disconnections after long periods of bluetooth being connected
Solution : Disable Battery Optimization on all bluetooth related services
Bug: version: lineage-14.1-20170302 -lineage-14.1-20170309
Bug: Phone doesn't rescan new media such as Whatsapp images, downloaded images
Temporary Solution : Manually rescan media
Ideally it should be in the first post of the LOS thread in Original Android Dev. But if you manage to maintain it, it could be referenced.
Hey guys, my phone is stuck on "Checking for updates" and I am looking for a solution. If I install this rom will it fix my problem?
Is it as easy as downloading it, starting on bootloader and $ adb sideload thisthing.zip ?
All the help is highly appreciated, I am not interested in modding stuff or special apps, I just want my phone to run again. Thanks.

Are you on stock rom? A simple reboot should fix the problem. And if you could send screenshots that would be good

If by stock rom you mean the original and official rom then yes. I've rebooted a thousand times now, wiped data and cache another thousand times, recovery/reset another hundred times, and got adventurous to flash a rom via adb sideload but it complained about invalid signature or something. Still stuck on "checking for updates".
The screenshot is a blue screen with a yellow progress line telling me "Checking for updates" just after the welcome and wifi verification., just like this one but with a different label "Software Update - Checking for updates": http://www.androidpolice.com/wp-con...nexus2cee_screenshot_20161020-090044_1024.png
