[Miscellaneous Android Development] Buzzwave:
I have about 15 ROMs here testing them and writing this overview but I cannot edit this post any more

Hi folks,

I like to do an overview of Lenovo A750 ROMs that are available on the web. Basically I am interested in Android 4 ROMs but we could list up 2.3 ROMs as well to have a complete list.

For that purpose I will update and extend this posting, that will be quite empty for the next hours. But I hope to get it filled this evening and with your help even more in the next couple of days.

I really hope that some people here speak Russian or Chinese and are able to post links found in foreign forums.

I found two topics in a Russian forum about A750 ROMs. One of them seems to be an overview:

http://forum.china-iphone.ru/viewtopic.php?p=640831#p640831

I already tried some ROMs like Anton and apkhot but not sure if I found the most recent version. And I did not find them by Russian forums.

BTW setting language to English in build.prop before you flash is not a big thing.

So I'm going to collect everything I got now and it would be great if you could provide more links and maybe a translation of the Russian and Chinese ROM overviews.

Please let me know if you find any invalid links.

(For rooting I used A750_CWMR_Touch_recovery.rar from cybermaus' repository.)

Rooting/Flashing Instructions

Set boot language

(Boot language might be set to Chinese (cn) or Russian (ru) so for being able to even find the settings menu you might like to set boot language to English (en) or whatever (we) ^^)

ROMs for Android 2.3 Gingerbread

Cybermaus S148 V1 (2012-04-28) Android 2.3.6

This ROM is not installed by loading a zip file from recovery. It will directly be flashed by USB cable. As the user data will not be overwritten, it had my German language selected. But the ROM only supports English and Chinese. Only some apps support German. So I had a mixture of English and German in my test. It has the GoLocker for Lenovo and the Idea Widget. That is how the launcher is called. So happy I found it.

It has some nice apps such as Car Mode or Lenovo Task Manager. Playstore is installed.

(Download a750_s148_120428_cybermaus_v1.rar from cybermaus' 4shared repository.)

BaderMQ S148 Multilang+Arabic Fix (2012-05-15) Android 2.3.6

This ROM is very nice. Its located to en/UK by default. Supports Multilanguage - at least German is supported quite good. Keyboard is only in QWERTY. It has two launchers installed and the nice lenovo lock screen. It has GoLauncher Ex but seems not to have a Widget. Lenovo Task Manager is a nice tool on that ROM. Playstore is installed but no File Explorer. I guess it's not rooted. Better link to discussion site appreciated if anyone knows.

Download Lenovo_A750_v1_BaderMQ.zip on 4shared.

ROMs for Android 4 ICS

Cybermaus S306 V1.3 (2012-06-18) Android 4.0.3

This ROM is mainly English and Chinese but has also some poor support of other languages (many items are still in English).

It has a Lenovo Magic Launcher with a buggy background, that may be fixed after changing the wallpaper a couple of times and rebooting.

Keyboard did not work until I installed the stock application ICS-keyboard.apk from here (German).

For installation first apply v1 and then update v1.3. Versions between can be skipped.

Download a750_s306_120530_cybermaus_ics_v1.zip and a750_s306_120530_cybermaus_ics_v1.3.zip from cybermaus' 4 shared repository.

ROMs that did not work for me

bgcngm S143 Hebrew fixed by BN (2012-03-29)

build.prop says it would be a S306 from 2012-05-30 and Android 4.03. Boot language is set to zh (Zhongwen - simplified Chinese). It also has a lot of Chinese apps in its system/app folder. To install I removed the assert from updater-script but then just got "installation aborted". Better link to discussion site appreciated if anyone knows.
