Tutorials
How to enter into recovery mode:
With Huawei U8836D completely turned off, press and hold VOL. UP key and turn on the phone. The phone will vibrate and after the splash logo appears, all keys should be released.​
Navigation under recovery mode:
Stock recovery mode: As soon as the splash logo disappears, an image with a triangle and an Android will appear and BACK key must be pressed in order to access menu options. Navigation is made using VOLUME keys (navigate up with VOL. UP and navigate down with VOL. DOWN) and MENU key to apply the action.
Custom recovery mode: As soon as the splash logo disappears, ClockworkMod Recovery menu will appear. Navigation is made using VOLUME keys (navigate up with VOL. UP and navigate down with VOL. DOWN) and MENU key to apply the action.​
How to flash custom recovery:
Download Huawei U8836D custom recovery and follow this MT657x flashing tutorial.
Warning: the package includes preloader, but there's no need to flash it. Make sure that you select only recovery to be flashed.​
Flashing a new custom ROM via the SD card method (update.zip):
Read this guide to know more about ClockworkMod Recovery and how to flash a custom ROM.​

Frequently asked questions (FAQ)
Question: I can't install your custom ROMs. Why? What am I doing wrong?
Answer: First of all you have to flash a custom recovery into your phone and then you are able to install my custom ROMs. Read the tutorials on post #2 to know the procedures.​
Question: I wanted to try one of your custom ROMs. Will I loose all my data after installing it?
Answer: Yes, you will loose all your data... unless you create a backup to restore after installing the ROM. There are two recommended ways to create backups of your userdata:
Doing the backup under custom recovery mode: navigate to backup and restore menu.
Using Titanium Backup to create a backup of your favourite applications.
Question: Can I fully revert to factory settings?
Answer: Sure, just download the stock update.zip and install it from recovery.​
Question: In phone specifications it's stated that it has 4 GB of eMMC, but only approximately 700 MB are available for internal storage... Can you explain me the reason for that?
Answer: The phone has indeed 4 GB of eMMC. Part of it is used by system and cache partitions, while the rest of the size is divided into internal storage (approximately 700 MB) and an internal sdcard partition (approximately 2 GB). If you find that an internal sdcard partition is useless (and have a big external sdcard), you can extend userdata partition (internal sdcard partition completely disabled). Jump into post #4 to learn how to apply that mod.​
Question: Somehow I have got invalid IMEI numbers. How do I restore my phone's IMEI numbers?
Answer: Read this tutorial. Don't forget to say thanks to its author.​
Question: Does my phone really have two IMEI numbers?
Answer: Every dual SIM smartphone based on MT65xx SoC has two IMEI numbers. Some just don't display both numbers on dialler when you type code *#06#, but if you go into Settings / About phone / Status / IMEI information you'll see the IMEI set for both slots.​
Question: How can I access hidden MediaTek engineering mode?
Answer: From phone's dialler type code *#*#3646633#*#*.​
Question: Are your custom ROMs patched to fix Android's master key (bugs 8219321 and 9695860) vulnerabilities?
Answer: No, but the solution to that is pretty simple:
Install Xposed framework (instructions on the support thread)
Install Master key dual fix module (instructions available also on it's support thread)
To check if system is vulnerable you can use one of the following apps:
SRT AppScanner
Bluebox Security Scanner
All credits to rovo89 for the amazing Xposed framework and also to Tungstwenty for the Master key universal fix.​
Question: I don't have this phone, but mine is also based on the same MT6577 SoC. Can I still flash your recovery and install your custom ROMs?
Answer: Even though your phone is based on the same SoC, there may be differences in other hardware components. It is not likely that recovery and ROMs will work on your phone so you may risk to brick it.​

Huawei U8836D internal memory re-partition
Initial notes:
Make sure that you have a full nandroid backup of your current ROM. If not, boot into recovery mode and make one. This is very important if you want to restore userdata after internal memory is re-partitioned.
Also make sure that you have a backup of your internal sdcard because it will be fully erased and disabled.
Warning: the package includes preloader, but there's no need to flash it. Make sure that your selection is according to the screenshot bellow.
Instructions:
Copy disable_internal_sdcard.zip to external sdcard (read note bellow)
Shutdown the phone
Open SP Flash Tool v3.1222.00 (or higher) and load the scatter file
Flash MBR, EBR1 and RECOVERY as shown on the next image (read flashing tutorial first):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After flashing is complete, boot into recovery mode and format /data
Optionally, if you want to restore previously saved userdata, go to nandroid backup / restore and restore data (advanced restore feature)
Install disable_internal_sdcard.zip file through recovery mode (read note bellow)
Reboot your phone and enjoy your extended userdata partition
Important update: All the new ROM updates which include AROMA installer also include a script to automatically disable internal sdcard if extended userdata partition is detected. Dismiss the part of the instructions that refers to the installation of disable_internal_sdcard.zip file. All the rest of the procedure is still valid and must be done before installing the ROM. That said, if you are going to apply this modification, you must re-install the ROM.
Please also note that this mod should only work with my custom ROM installed. Be warned and please do not blame me if you run into some problem while applying the mod over stock or any other custom ROM

Thanks Bruno for the recovery image. I will get it flashed when I am back home.
I have noticed that actual phone reception signal levels are lower than my W3+ Thl phone. Have you noticed any difference in signal levels where you are against your ZTE 970? It may be just the algorithm they use on this one.
I love the tricolour led but lack of tts settings is a little annoying. Overall, I am very pleased with it so far though.

Thanks Bruno - I look forward to some custom ROMs - I'd managed to dump the entire original ROM last week having made a scatter file then add Gapps but nothing else. I'm completely new to modding and happy to do any testing etc. My phone had the original factory ROM.
Yes the signal reported does seem on the low side. The battery drain does seem a little high as well so far even when not constantly playing with it!!) - wonder if the CPU governor is set properly?
Edit - gave the phone a good full charge overnight - before using it today and down to 90% after 12 hours - with little/no use - so about normal for a smartphone. Probably hadn't charged it fully before!!

Thanks Bruno, my phone is at this time only paperweight, so I am waiting impatiently for your ROM.

Thanks for the recovery img Bruno.
For those of you who want to install the Huawei HiSuite app on your phone and desktop but can not get a link from the Huawei site here, I have uploaded it to 4Shared and you can download it from this folder here.This suite allows some syncing to be done and some backups etc. Full details on the Huawei website.
EDIT:
Bruno, not quite sure what happens but after flashing your custom recovery and testing it, I reboot and the original recovery returns! Just to make sure that I was not going mad, I flashed the custom recovery image again. I can use it, I have even done a back up of the system but after running the phone and a reboot, the original recovery returns again.
Is there anything to resolve this, are you having same problems? This is really strange.
EDIT:
From MSprecher
The custom recovery is allways overwritten by the stockrecovery when booting the phone. This can be avoided by rebooting from within the CustomRecovery right after having flashed it. There should be an extra-option after the reboot-command in CWM-Recovery to avoid this.
Enjoy Matthias

Yes, that happens with the stock ROM installed and the workaround for now is the one Matthias already told you. With my custom ROM installed that will not happen.

Thanks, the option to allways use custom recovery does appear and you have to confirm this option before first reboot. Thanks guys.

Bruno it will be great (i don't know if it is possible) if the new rom could aggregate the memories, i mean the same you did on the ZTE, putting the same storage for programs and the only sdcard is the external.

Yes, I plan to release the same extended userdata mod as I did for V970, but not integrated into the ROM, so that users can choose want they want.

Btw, i found now in my small experience with the device two problems:
- Some apps can't be installed (Asphalt 7, Sports Tracker, WorldMate, etc.) which were working in my previous Gsmart G1345. Is it due to the Mtk CPU??
- Comparing again the two devices, this one has a worse GPS, much more inaccurate and very slower in getting signal.
Lets wait for your fantastic Rom, Bruno.

Crake you are right, I cannot install profile scheduler+ or EasyProfiles Pro due incompatibility. DualSIM?

No, that is a problem of permissions. It will be working on the custom ROM, don't worry.

I have already enabled Speech category (Voice search and TTS output) under Language & input menu, so you'll be able to access TTS settings.
By the way, I will release the first custom ROM today. It will not support any additional language other than the default ones - English and Chinese (Traditional and Simplified) because I don't have time right now to do it. The support for more languages will only be included in the next version. Hope you all understand!

awesome!!
u know I have been waiting for a rom for this phone u8836D from day one, because i messed it up on the day i received it, especially replacing the system folder files etc.. just pain in the bum to not have a rom (even stock rom) handy. And it's been endless waiting...
when your first post came up, I opened your shared folder for like a million times to try to find the rom, but just recovery img there, i thought I missed something maybe and read all your posts another million times...
Now just 10 mins ago, it appears in that lovely folder just like a magic...
Will let you know how I go...
i haven't learned my lessons from my last 5 Android phones...all I want now is just clean system with google services on...
When we get that, we star talking optimization and who's ass is more sex lol

Okay, I have just uploaded the first custom ROM for U8836D into my 4shared folder.
Please read what are the fixes / modifications that I've made over the stock ROM on the third post of this thread or in the readme.pdf that's inside the .7z file.
Enjoy! :fingers-crossed:
EDIT: I forgot to say that this ROM clears all userdata, so make a backup first using Titanium Backup, for example. But please note: do not restore any contact / messages database. Let Android create it from the scratch or else, if you restore everything the CID bug will be there again!

So how do I restore (and backup) sms, contacts and call logs to avoid CID bug?

Simple: you don't restore. Just sync the contacts again with Google (or Exchange), let the database be built from scratch and that's it. It's either that or having the nasty CID bug back...

[ROM][MOD] Lenovo A820

Dear Owners,
Discontinued
In this post you can find a multilingual (mainly European) modified rom for the smartphone Lenovo A820.
IMPORTANT NOTE!
The newer phones do not work well with S138 or older kernel (no info about S147).
The sympthom is that the touch screen works on inappropriate way: after the first screenlock it does not work again.
For this reason it is highly recommended that update your kernel if you have got this issue.
The kernel changer to S150 zip can be run from modified recovery (CWM, TWRP, COT, Carliv, etc...).
Note that all the things in this thread you do with your phone can be dangerous. I cannot take responsibility for your phone damage.
So, do it at your own risk.
Before you do anything, I recommend you to save your current ROM (I would say it is mandatory!)
There are many ways to save and I highlight some (links will be added later):
1, for non-rooted phones:
- SP_Flashtool, readback option.
- CWM (or TWRP) backup, if it is available on your phone
2, for rooted phones:
- MTKDroidTools backup
- command line dd-backup
In order to install this ROM, you need to have CWM recovery on your phone.
If you have not got this recovery or you do not know which recovery you have got, you have to read post#3 before you do anything.
If you get error during the installation of the ROM, see post#4.
The restore option of the CWM rcovery is not as good as it could have been expected, so please read post#4 carefuly for CWM restoration issues, tricks.
Update: CWM 6.0.4.0 with S150 stock kernel.
Just to clarify the power-on modes:
Normal phone mode: press the power button
Meta mode: VOLUME DOWN + POWER
Factory mode: VOLUME UP + POWER
Recovery mode: VOLUME DOWN + VOLUME UP + POWER
Consider the warranty issues, you need to backup you rom.
In addition, I always suggest to do a backup before install any new ROM to your phone.
You can do it with CWM recovery in backup menu.
About installation in general.
Pre-requisites: CWM recovery menu installed on your phone. (This ROM can be installed from CWM recovery.)
The ROM file must be saved on your physical SD card.
Enter into CWM recovery.
In CWM recovery you can go up/down with the volume up/down keys. The “enter” is the power button.
Choose the “install zip from SD card” menu item.
Choose the “choose zip from SD card” menu item.
Select the rom you want to install.
Choose “OK” in the menu item.
If you need a detailed explanation of its use, see the tutorial : http://bm-smartphone-reviews.blogspot.com/2012/02/complete-guide-to-clockworkmod-recovery.html
Right after the ROM installation has been finished, you can install gapps as well, before restart.
Windorws driver installation:
Please do not ask me about it. I use mainly Linux, which is more friendly.
What I did in XP under Virtualbox was:
Downloaded the Lenovo drivers from here: <link>
Manually added the com ports in control panel.
MOD CP4.0
V1
The modified rom has got the stock kernel - Lenovo A820_ydss_S135_130403
This completely changes your phone appearance, your Lenovo UI will be disappeared.
Also Lenovo applications are not integrated to this rom.
It will look like the stock Jelly Bean.
Main features:
-The firmware is rooted.
-Boot logo, boot/shutdown animations and sounds are changed to Lenovo.
-Minimalist appearance and content, for this reason you have to install google applications manually, from CWM recovery <link>. After gapps installation everything works well (many people wants to have mainly Google Play. It do work.)
-Slide unlock.
-Multilingual. For supported languages, see the screenshots.
-The default language/region is Hungarian, but you can easily choose your one.
Known bugs:
- I found was that the charging logo with turned off phone is not proper.
-the camera does not work adequately in video-camera mode.
-the default setting in some of the application is V987.
V2
The modified rom has got the stock kernel - Lenovo A820_S135_130403
The camera was changed to a non-multilingual one. It looked that the black screen in camcorder mode solved.
But after googleapps something went wrong... black screen again.
V3
The modified rom has got the stock kernel - Lenovo A820_S135_130403
In V3 there is not any significant changes (camera app was changed back to the multilingual one), but I modified the gapps, which caused the camcorder issue.
So, for this modified rom you need to use this gapps.

There is no default ringtone set! Right after the installation you have to set the ringtone, message alert and so on... otherwise your phone will not play sound...
Important feature!
If you have already repartitioned with the script, you can simply install this ROM, it will recognise that the repartition had been done; and you do not have to run "disable internal SD card" script from CWM.
But please note that this function is onyl available with the repartition script; with Meteos rom editor repartitioning this function is not available.
Right after the installatio, there is not any sound set. Nor the ringtone, nor the message an alert. So, you have to set it first.
Available on mediafire : Link
md5sum: 86e241fcac6faf4fa6baf0f9cc4a18a0
Additional possibility:Change of FM radio
The FM radio can be changed back to Lenovo’s one with this script. It was requested by some people due to the fact that Lenovo’s FM radio can work without connecting the earphone.
The link is here. http://data.hu/get/6494163/FM-radio-change.zip
You can install it from CWM recovery, with the same method that you used during the installation of the ROM. This script does not affect any other part of the ROM, but the FM radio.
Repartition
Please DO NOT USE IT for Lenovo-based ROMs. Sometimes it can cause bootloop or other inconvenience.
The repartition of internal memory of the Lenovo A820 phone has been solved already.
With this action youd intednal SD card will be disappeared and will be added to the /data partition.
Before you do anything, make a CWM backup, and save all your data from internal SD card!
The easiest way is to use this CWM script, if you want to have the maximum available size (2,7GB) for the /data partition.
You have to install it from CWM recovery.
After the installation you need to do a factory reset.
After the factory reset, you have to disable your internal SD card, with CWM script.
And then, you can reboot your phone to check if yo have got the new size of /data partition:
settings --> storage
"internal data storage; full capacity 2,7GB"
"internal SD card; full capacity <your physical SD card capacity"
If the above data appear, you have successfully repartitioned you phone's internal memory!
If you want to have your data back, go into CWM recovery, and choose
backup and restore --> advanced restore --> <choose your save> --> Restore data
And then, your data are available again, after the reboot.
Please do not use it, if you do not want to have the 2,7GB of /data partition!
For Lenovo-based ROMs you need to use Meteos-apk for repartition of A820.
Internal/external SD card exchanger
If you want to use your physical SD card as the default one, and still want to use your emmc-SD card (aka internal SD card by default), you can change it by this CWM script.
Important link in summary:
The driver what works is here.
The original stock recovery is here
The autoroot package can be found here.
The preferred CWM is here.
The root script is here, you can install is from CMW, and your phone will be rooted.
The usable Flashtool is here.
The scattel file for Flashtool is here.

CWM recovery
Installing CWM on your phone
You need to install proper drivers to your computer.
Available (ported) CWM recoveries:
With newest kernel:
CWM recovery 6.0.1.2 - S150 - ported from [email protected] ZTE V970 recovery.
CWM recovery 6.0.4.0 - S150 - ported from [email protected] ZTE V967S recovery.
CWM recovery 6.0.1.2 - S138 - ported from [email protected] ZTE V970 recovery.
CWM recovery 6.0.1.2 - S135 - ported from [email protected] ZTE V970 recovery.
Option 1, with SP Flashtool
Download the SP_Flashtool software to your computer. Extract it to a directory, where you want to run it from.
Download the scatter file, which you will need if you want to use SP_Flashtool.
Download the CWM
(5.5.0.4, 6.0.1.2, 6.0.2.8; it is your decision)
Run the SP_Flashtool.
Browse your scatter file.
Choose only the recovery.
Tick the “DA DL all with checksum” (you can find it close to the download button). It is a really important point!
If your phone is connected, let’s disconnect it from the computer.
Turn off your phone. Take the battery out from your phone for 5 sec. Insert the battery to you phone. Keep it still turned off.
In the flashtool press the Download button.
Choose OK to the warning message.
Connect your phone to the computer.
The flashtool will flash the recovery into your phone.
When the green circle appears, wait for 5-10 secs, and the unplug your phone.
If everything went well, you can enter into the recovery menu (see 1st post, power-on modes)
Option 2, on rooted phone, with MobileUncleTools.
Install MobileUncletools 2.8.x or higher from the Play Store.
Save one of the CWM I linked to the root directory of your physical SD card.
- select menuitem Recovery Update. The program will list the available recovery images.
- choose the one, what you want to install
- It asks back: "Are you sure flash recovery!" - Use recovery file: <name of the recovery what you choose previously>. Tap to OK.
- After the flashing process it offers you to reboot into recovery. If you tap OK, it will automatically reboot your phone to recovery. If you tap cancel, you can use your phone as a phone.
- Before you tap to "reboot to recovery", I suggest you to wait approx. 5-10sec.
Use of the CWM.
If you enter into the CWM (6.x.x.x) recovery, the following buttons can be used:
- Power button : “enter”
- Volume down : step down in the menu
- Volume up : step up in the menu
- Soft key “option”: step down in the menu
- Soft key “back” : step back in the menu
In 5.x.x.x you cannot use soft keys, but the physical buttons works on the same way as in the case of 6.x.x.x
CWM restoration
I experienced failures in restoration of the CWM backup.
This was a real surprise for me because I have not faced this issue with other MTK phones.
So, the issue is that the CWM restoration does not work immediately.
In details:
-I saved the stock rom by CWM 6.0.1.2 (CWM was complied by Bruno, and I modified it for A820)
-For checking the restore function, I did a factory reset: the phone stopped working.
-I did the CWM restoration, but still the phone stopped at the boot animation. And stayed it for 15min. I removed the battery then.
In order to solve the issue, the following method was done:
-In the advanced restore I choose the restore /system (only!)
-After restoring the /system I turned off the phone took the battery out, waited 5 secs, inserted the battery back.
-Turning on the phone it worked again with the restored data, BUT the internal SD card was injured! I formatted the internal SD card – with this action I lost all my data that were saved on the internal SD card.
So, please be careful using it! Save your internal SD card data before the CWM restoration!
This was experience in case of all the available CWM (5.5.0.4, 6.0.1.2, 6.0.2.8).

Installation issues
Post#4 troubleshooting
If you cannot install the ROM by an error:
Code:
assert failed: getprop("ro.product.model") == "Lenovo A820"
E:Error in /sdcard/Lenovo-a820-update-CP4.0-v1.zip (status 7)
This is a safety feature, not a bug.
This error message is a warning that you have not got the proper CWM. (Most of the available CWMs are based on ZTE, STAR phones and contain improper model description.
My CWMs contain the proper one, I modified them, so you need to install a CWM I mod for Lenovo A820.
In this case you have to update your CWM to a ported one that I did.

Great!
I would love an multi lingual rom, but for now I just want to root it. (ones it gets delivered that is)
Are there tools specific for this device to root is with out flashing?
Checking out your rom in the meantime. :fingers-crossed:

If you have got CWM recovery on your phone (or a chinese one that has got "xx SD yyy ZIP" menuitem), then you can use root-zip, installing it from CWM recovery.

Thanks

Thanks
Where are the screenshots?

please add some screenshots.

I tried to upload some, but the server was down that time.
I will try it again tomorrow.

Thanks for this rom, I flashed it succesfull on the Lenovo A820, it also takes away that terrible skin from Lenovo.

Gapps link
Thnak you for your ROM. I tried it for a couple of hours and there some minor problems that I don´t know if there are rom related.
1. There is no link to the gapps, so I downloaded a random one and I have errors with google search.
2. The videocam record with a green band on one side.
3. The gps is slow, doesn´t pick satellites easily.
4. If you choose automatic time the it always consider that you´re in china. If you choose manually your timezone then it is ok.
Overall it is a very well-done rom and I would keep it for daily use.
Thanks

1. Are you sure you downloaded the Gapps for Android 4.1.x? You should have this gapps version: gapps-jb-20121011-signed, this the right version you should flash. I first flashed the rom and after that the gapps.
I have reproduced your issue and you need to update the Google search app in the playstore, after that the errors are gone.
2. I have reproduced what you reported, I want to try if I can grab the original camera app from Lenovo and see if it still has the issue, but I don't think its a big problem, I bought the phone for someone else, but this issue is not to big, I don't suppose people often record with an smartphone and this rom at least got Dutch in, the original phone firmware was bloated with China Unicom bloatware, Lenovo skin and had no Dutch support.
3. Try GPSfix, ussualy this kinda works, but the MT6577 chip was know for having GPS problems, perhaps its the same with MT6589? But there are many apps out there that can help you fix it.
I think this in a great rom, Lenovo is a big brand in China, so many will choose Lenovo and with this rom you get rid off the terrible lephone skin, I mentioned this rom in my review about this phone
Oh here you got some screenshots.
Feel free to use them in the OP.

Don't know about you but I do use my device a lot for video recording.
I think it is imperative that all basic functions work flawlessly.
The custom rom's with android 4.2 also have an video bug at this time, which is a bit unacceptable.
I'm sure it will be sorted out :victory:

Well yes, but having fully Dutch support is better, you can always flash new update off the custom rom when it get fixed. I only recorded a few time video with my own smartphone.

1, I have added the link.
2, Thanks for the feedback, it is really useful to know. The playback contains the green band, the file itself does not.
I changed the kernel to the '130'-one, and now it works with the camera application, and the playback is also correct.
3, You shall try the EPO / A-GPS support for getting it better. Or thy DexterMorganNL's suggestion.
4, I have never faced this issue, but in the new version I set the default time zone to London.
The new one is available, you can see it in the first post.

Thank you for your time. I will try the new version. But, why have you used an older kernel?
By the way, with version 3 I also had some problems with the gyroscope when playing Real Racing 3.
Great work

Its great you released the update so fast, you brought us really good work. I think new owner off this phone is going be thankful, they requested me to buy a phone for them while I'm in China, and when I got it it was not fully Dutch supported, had the terrible skin.
So its great have this phone, because this way I can deliver it without the Chinese bloatware and with full Dutch language and ofcourse Google apps.
EDIT
The newest release gives me a black screen after I boot it up after having it flashed, so I have reverted back to your previous release.

OK. I'm ready to weep.
I've previously had a ROM from NeedRom on my A820.
I'd like to give Cappa's ROM a try, but when I try to install from CWM Recovery I hit the Error outlined in Post 4.
I then follow the advice of Post 3... But there are no links to A820-compatible CWM Recovery installations. I found one on a hungarian site linked to Cappa, but all I get is a .img file and no idea how to get that on to my phone.
Can anyone post detailed instructions, or send me to a page (in English) where I can find instructions on how to get the ball rolling so I can use Cappa's ROM?
Thanks.
Google is my friend. Yes. But Google Translate isn't.

Update, I think I sorted it...
Bit of imagination (and could have totally done the wrong thing, but it seems to be making progress...)
I decided to take a known ROM install that I've tested and that works, which has a recovery.img included, and I renamed the recovery.img to recovery_bak. I then renamed my 'new' CWMRecovery image to recovery.img and dumped it in the directory with the ROM data that I got off NeedRom. I loaded up SPFlashTool and loaded the scatter file from that ROM, then deselected every component except 'recovery' and flashed it.
End result is that I have a phone which recovery-boots to the version 6 cappa-modded CWMR which I found on the Hungarian site, and in turn that CWMR has just installed both the required ZIP updates outlined in Post 1, and Cappa's ROM is now sat on my second A820 awaiting setting up...
I hope I did the right thing, and this won't come back to bite me in the ass later... The newer recovery.img was slightly larger than the old one, but I'm assuming that the scatter file isn't about storing specific pieces of the ROM in specific places based on exact size of file, and thus perhaps all things will continue to work swimmingly.

Needs further work:
External Storage, will be available once you take your SDCard off, and insert again.BUT can cause random reboots.
BT, will give you FC when you turn on, but it works OK
You tell me
In addition to the ROM changelog:
External SDCard: as I said it can cause random reboots, also if you reboot the TAB it can cause bootloops,in this case just remove the SDCard and the TAB will boot just fine. Last case scenario, remove the SDCard and wipe dalvik
Benchmarks: Well its noticeable the increase in speed and less RAM usage on the AOSP Betas.
Some guys are asking me why the Antutu scores are so similar with the stock Asus/And my custom ROM?
Well you should check the ram usage/FPS between the ROMs And since the Aosp doesn't fully support the external SDCard, this will give about less 2k on Antutu scores (Storage IO / database IO)
So... If you really want to compare Antutu scores, remove your External SDCard from the stock Asus/ V1.1r2 Roms.

BACKUP!
Start here for a guide to extracting a ROM dump from your T815 and processing it to create a backup you can use to restore your phone if anything goes wrong for you
Custom Recovery and Root Method
I have ported PhilZ Touch Recovery V6 (6.59.0 - based on CWM 6.0.5.1) to the T815. Installation method and rooting instructions can be found here
Custom ROMs (list will be updated as new ROMs are posted)
[ROM] [PussyFap V3][KitKat] ZTE T815 - here
[ROM] [Pure LG G3][KitKat] ZTE T815 - here
[ROM] [Cherry ROM Lite v2.1][KitKat 4.4.2] ZTE T815 - here
[ROM][Amgoo OS][KitKat4.4.4] ZTE T815 - here

How install custom recovery and root ZTE T815
DISCLAIMER:
Rooting your phone and using custom Recoveries and ROM's 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 knowledge about the phone and phone utilities also.
Make sure that whatever you do, you are doing it at your own responsibility.
I have been able to port PhilZ Touch Recovery V6 (6.59.0 - based on CWM 6.0.5.1) to the ZTE T815. To flash this recovery to your device you will need the following:
- USB VCOM Driver - Installation tutorial and download of driver here (Don't worry that it says MTK6577, it works fine with MTK6572 based devices)
- Smart Phone Flash Tool - Download for all versions can be found here - scroll to the bottom of the list to find latest version
- Scatter file and custom recovery image - download here
- PC and USB cable
Method:
1. Follow the tutorial and install the USB VCOM driver.
2. Install SP Flash Tool - once installed, run as administrator.
3. On the "Download" tab page, click the box on the right hand side named "Scatter-loading". Browse to the location where you saved the downloaded "MT6572_Android_scatter.txt" file, select it and click "Open".
4. In the lower section of SP Flash Tool screen, tick the box next to RECOVERY. This is the ONLY box that is to be selected.
5. On the RECOVERY line, go across to the to the blank cell under the "Location" heading and click on it. Now browse to the location where you saved the downloaded "recovery.img", select it and click "Open". The line should now show the location of the file.
6. Turn off your phone and remove the battery.
7. On SP Flash Tool, click the "Download" button at the top of the page and THEN connect your phone to the PC via the USB cable (battery still out).
8. All going well, you should now see the download progress being displayed across the bottom of the screen. Once completed, you will see a big green tick displayed in the middle of the screen. Success! Your phone now has PhilZ Touch Recovery installed.
To access Recovery Mode, from power off hold down the volume up button and power button together for around 6 seconds (press and hold volume up first then press and hold power). You will now see the recovery main menu.
Root: (after you have your custom recovery installed)
1. Download supersu.zip (latest version) here - thanks to @Chainfire
2. Send zip file to your SD card.
3. Boot into recovery and install zip from SD card.
4. Reboot - your device is now rooted.
Important:
Make yourself a backup. (Note: the external SD card is /storage/sdcard1 - if you try to backup to sdcard0, you will run out of memory.)
To bring this PhilZ Touch Recovery to you, thanks and credit must be given to the following:

If you are in recovery mode with a purple background and a green android in the middle then you are in the recovery mode that we set out to achieve. Just touch "go back" on the screen until you are at the main menu and then select "reboot phone now" and you will boot to your stock OS.
If you are on the black recovery screen (stock recovery), it means that some part of the process did not work and you didn't get the custom recovery flashed correctly. You can navigate through the stock recovery menu by pressing volume down to select the line with the option you want and then confirm your selection with volume up (which I think goes against "normal" thinking and is a trap for making incorrect selections, so be careful, says he who has fallen for this same trap and blitzed his phone!).
You need to get back to the "reboot now" option and then try the process again (be sure you have the USB VCOM drivers installed properly.):good:

is there any new roms coming in? what about CyanogenMod? are you guys making a "pure" android ROM for T815? i didn't like the ***** fap rom as it doesn't work well with small screen, lg rom is perfect but slow, is the cherry rom near stock??
PS: great work keep up. if you could maybe remove the dual sim notification as i only have 1 sim slot, also maybe its a good idea to upload de-bloated stock rom for t815

Thanks for your feedback. I do have plans to upload more ROMs as I port them and get most of the bugs squashed but, as I am on a massive learning curve regarding porting myself, it is taking a bit of time. I don't reckon I've done too bad so far for only a couple of weeks! I will leave the CyanogenMod ROM for a while, as it looks like it is one of the more complicated ROMs to port, but I will try to get it up here at some stage. I am working with a pure android ROM at the moment so hopefully that works out and I can upload it soon. The Cherry ROM is debloated and has some nice features but the only way to find out is to give it a whirl.
As for the dual sim thing, I am still trying to work out how to modify the ROM to only show the one sim (as I said, still got "L" plates on) and once I work out how to do this I will repost the corrected ROMs. I agree that a debloated stock ROM is a great idea so I will work on that when time permits.:highfive:

LOL!:laugh: Around 6 month ago I was looking for a cheap phone to mod and my final choice was between the Tempo T815 and Pixi 3(4), the Pixi winning out because it was $5 cheaper. It was the right choice as I found @kirito9's thread which was crammed full of info and ROMs. I learned a few things about working with the Mediatek MT6572 chipset and porting ROM's (thanks again to @kirito9 here, absolute legend) over there, all the while watching a small thread about the Tempo T815 where they had all stopped posting as no one could get root on the T815. I thought I could take the bits that I have worked out and apply them to this little supported device so here we are. I am no expert on all things MT6572 but I am working things out slowly so hang in there and I will put more ROMs and helpful info up here when I can.

Full ROM Dump Backup & Read Back Method
This guide will show you how to make a full ROM dump of your ZTE T815 (Mediatek MT6572) device. It can be used to make a full backup at anytime but I strongly suggest that you follow this procedure prior to making any modifications to your device. That way you will always have a completely stock unmodified image to return to if things go bad or aren't what you expected. Don't say you haven't been warned!
Things you will need:
- ADB Drivers - here or here
- USB VCOM Driver - Installation tutorial and download of driver here (Don't worry that it says MTK6577, it works fine with MTK6572 based devices)
- MTK Droid Tools - here - scroll to the bottom of the list to find latest version
- Smart Phone Flash Tool - Download for all versions can be found here - scroll to the bottom of the list to find latest version
- Notepad++ - here
- A PC and USB Cable
Preparations:
- Install ADB Drivers system wide and follow tutorial to install USB VCOM Driver
- Install Notepad++
- Create a folder somewhere convenient (e.g. desktop) and give it a name related to phone/mods etc.
- Into this folder, install MTK Droid Tools and SP Flash Tool.
Process:
Make Scatter File
Run MTK Droid Tools as administrator. Once the program has started, connect your phone via the USB cable and you will see that your phone information loads up on the left side of the page. Below this you will see a button that says "Block Map". Press it. You will now see a screen displaying Block Info and at the bottom left a button "Create scatter file". Press this button and save the "MT6572_Android_scatter.txt" file to the folder that you made earlier. Don't close MTK Droid Tools, just minimise it at this stage and unplug your phone.
Read Back ROM From Phone
Run SP Flash Tool as administrator. By default it starts on the Download tab. You will see a button labelled "Scatter-loading" at the top right of the screen. Press this button and direct it to the "MT6572_Android_scatter.txt" that you just saved. Once loaded, change to the "readback" tab along the top and then click "Add". A line is added below and you need to click in the blank area under the heading "File". Browse to the location where you want to save your ROM dump (in that same folder again would be appropriate) make sure you retain the file name of "ROM_0" and press "Save".
There is now a dialogue box that pops up, "Readback block start address". The "Type" must remain as Hex. The "Start address" should also remain as it is - 0x0000000000000000. The "Length" address is determined by the address of the partition we wish to finish our ROM dump at. I would suggest that we use the address of the last partition in the phone. To find out this address we need to examine the scatter file. Open the scatter file with Notepad++ (this will keep the formatting in place). Easy way is to right click on the file and select "Edit with Notepad++" from drop down menu. Scroll to the bottom of the page and find the FAT partition information. The "linear_start_addr:" value here is where to end the ROM dump so carefully copy the address and paste into the "Readback block start address" dialogue in the "Length" field. (e.g. the linear start address of my FAT partition is 0x97140000 so this is the figure I enter into "Length").
Note: If you have already been using your phone before doing this backup method, you may wish to create a ROM dump that excludes your personal info. If so, you might choose not include the CACHE and USERDATA partitions in the backup so you would end the ROM dump at the linear start address of the CACHE partition (in my phone this is 0x36340000, for example).
Once the "Length" value is entered, press OK. Turn your phone off at this stage. Once it is fully powered down, click "Read Back" and then connect your powered off phone to the USB cable and all things going well you should see the progress bar at the bottom go blue and start moving. Once completed successfully you will see a green circle with a tick in it. Done! Disconnect your phone.
Process ROM For Use With SPFT
Turn your phone back on and when ready reconnect to MTK Droid Tools. Change to "root, backup, recovery" tab and press on the button labelled "To process file ROM_ from Flash Tool". Browse to your modding folder location and open "ROM_0". The processing will start and you will be prompted to make a CWM recovery automatically. Answer "No" and then "Cancel" when it asks to choose recovery. You will see the process in action and it will end with the message "Task is complete" at the end of the script. The folder containing this processed backup is located in yourmoddingfolder/Mtk_Droid_Tool_v2.5.3/backups. If you examine the contents of this processed ROM backup you will note that the output folder now also contains a scatter.txt file.
Restore process to follow - edit soon:good:

That way you will always have a completely stock unmodified image to return to if things go bad or aren't what you expected. Don't say you haven't been warned!

Assuming port was supposed to be post, you absolutely can borrow it, mate. [emoji106]
