[Android Q&A, Help & Troubleshooting] PeterMarkoff:
I just installed AOSP 2.0 ROM, which is prerooted with GAPPS and Xposed disabled by default over my official 1443 rooted ROM with Chinese TWRP, everything following steps went fine, first boot takes 2-3 minutes actually, much faster than expected 5mins, Xposed together with GravityBox after installing/activating and two reboots work fine! Your personal data (photos, MP3, etc.) on internal storage after wiping cache/dalvik/data are preserved in "0" directory, so I didn't need to waste time with doing backup but better be sure. Wifi, SMS/messaging, calls, Miracast all work fine, IMEI was preserved as well (so not really needed MTK NVRAM tool). Outlook.com contacts and calendar synchronization work both fine, I don't use GMail/Google blocked in China, but with VPN they all worked fine showing me my data. Can't test 4G since I don't have 4G data plan.

By default is selected Dalvik runtime, not ART, didn't try if it won't affect Xposed functionality, not really big fan of ART since it's still buggy with some apps.

There is Magic touch option, but could not figure out what is it doing, double tap on screen doesn't switch on the screen.

There is no problem with Xposed+GravityBox except I can't make status bar transparent and I can't change color of signal icon and remove 3G next to it, but it's minor annoyances compared to Lenovo ROM.

What to fix for developer:

1. Hardware information (in About) is displayed wrong as 1.4GHz + 1GB RAM + 8GB ROM + 5.5" 720P display, should be pretty easy to fix, but it's minor annoyance not affecting usage at all. Machine total capacity in storage is also displayed wrong as 8GB again, although it's correctly displayed in File explorer.

2. SuperSU is in Chinese, but can be easily changed to English by installing update from TWRP, which I later did to newer version and experienced no issues.

3. Preinstalled Camera+Gallery apps are not Kit Kat stock apps but Lenovo apps (no problem to uninstall them, they are not even system apps), I don't understand why and later I installed stock APKs for Google Camera (Play Store, but I am using DSLR camera app anyway) and Kit Kat stock Gallery. iFlashlight app seem completely useless as well since there is Torch in quick tiles.

The latter two should be easy to fix to replace lenovo camera+gallery by Kit kat Stock, remove useless iFlashlight and change SuperSU to English.

So now finally after almost 3 months I have decent phone with normal AOSP ROM with Xposed+GravityBox and without shiny battery cover (which I replaced with shell, since I ran out of patience waiting for matte battery cover from 3rd party producers) and everything seem to be working properly except signal color and not transparent status bar (+incorrect hardware info in system settings).
[Android Q&A, Help & Troubleshooting] uvris:
That's all great stuff to know. You have actually inspired me to get the AOSP on my phone too. Everything went alright except the SuperSU part as I cannot get rid of the chinese version. I tried to flash SuperSU-v2.14.zip but nothing happens. In fact I even "lose" the root and have to reboot again in order to get it back.

Can you please tell me step by step what you did and send me the SuperSU zip file you used?
[Android Q&A, Help & Troubleshooting] eLPeReC:
I've read about that problem, try another SuperSU zip version, I think 1.99 should work. Good luck!

I can't try it because I'm on a Spanish version of VibeUI ROM (thx to TIODE & MANOWARACERO:))

Do you have any problem restoring apps from Titanium Backup?
[Android Q&A, Help & Troubleshooting] PeterMarkoff:
SuperSU 2.02 worked for me fine, here is ZIP file I used on multiple mirrors:

http://mir.cr/1LV81MVC

I didn't use Titanium to restore apps, it seem to be working for doing backup, freezing, but I nstalled everything from scratch, that's the safest since anyway I plan to stick with this AOSP ROM probably until Lollipop as I didn't find any serious issue for me.
[Android Q&A, Help & Troubleshooting] uvris:
Worked like a charm :) Btw, can I delete root explorer now?

However, I have another problem with this ROM. When I plug it in with the usb cable, my PC sees the internal storage -which I mostly use instead of the SD card- as a CD-drive.

What can I do to fix that? The SD card shows up normally.

PS: None of the mirrors you provided work :eek:

Root explorer is not essential for anything, it's just normal app.

As for storage, I don't use SD card so not sure if SD card can cause some problems with visibility of Internal storage, but when I plug in phone into my W8.1 laptop it's properly recognized and displayed as MTP device, so it will be your Windows/driver issue or something to do with SD card that maybe only one device can be seen at once, I guess I will start using SD card when I will run out of space. :) There are several options for USB computer connection - Media device (MTP) work fine (and this is also the only connection available in original Lenovo ROM!), PTP works as well but it's more limited than MTP so no point using it, USB storage doesn't work (and also it's not available in Lenovo ROM) - storage is displayed but not possible to access, Built-in CD-ROM will display as empty CD-ROM drive (in Lenovo ROM it would be filled with USB drivers and Lenovo suite but I guess removed from ported VIVO ROM to save space and useless software), so no news here, MTP works same as in official Lenovo ROM and should be used, USB storage never worked no matter what ROM.

As for mirrors, they worked for few days, not going to reupload it again, not so difficult to find older versions of SuperSU on internet as I did.
[Android Q&A, Help & Troubleshooting] uvris:
Well MTP works now just fine... I don't know what was going wrong so far. Maybe I was mainly trying the "usb storage" which now I know it does not work :p

Since you are the only person I know on a forum who uses the AOSP, I'm going to ask you things every now ans then. So, here is the thing. I downloaded an app showing the battery consumption and I get a 44.9% on the android system. Is this normal? It feels a lot.

Hello,

Thanks for your great info!!!

I own the lenovo A806 (for chinese market, if I knew this in advance would not have bought it!).

I have extended knowledge and can follow your rooting-advice perfectly. However, I am for more than a weak now stuck on the MTK preloader-driver. I know MTK-droid, SP-flash, CWR, TWRP. I have got several MTK driver+advice from my Wholeseller.... I have USBdeview, so I installed, uninstalled, installed, uninstalled several Vcom, lenovo and more drivers.

I spent about 50 hours trying. So really frustrated now.

Any more advice??

Thx in advince maestro.
[Android Q&A, Help & Troubleshooting] jasonmk01:
I am assuming you are having trouble loading the roms via the Flash Tool? If this is the case what worked for me was:

1) Make sure to extract the .RAR to a directory before loading it in the Flash Tool

2) Just before you press the download button in the flash tool you need to:

a) power off phone

b) unplug USB

c) remove battery

d) plug in USB

e)_press DOWNLOAD in Flash Tool

f) quickly replace battery into phone​

Hello

Hello,

I live in Canada and decided to purchase this phone (A808T) from LightInTheBox. The phone's arriving soon but I read that the headphone output is absolutely terrible. I would like to know if this is true, because if it is then I'll return this to sender as soon as it comes to my door, as I don't mind spending an hour getting AOSP on there but I can't live without good headphone quality. Can someone help me out?

Go to your contacts and click on your settings/more button on your phone or hit the three dots in top right corner, that will bring down a menu then choose more features and settings, now you gonna choose more display features and then change number match bits from 11 to 7.

Help for complete newbie

Hi everybody,

I am new to the forum, but I also have bought a Lenovo A806 from China. While I am very happy with the specs (for the price), I am not happy at all with the Android version and the many apps that come pre-installed with the mobile. I don't have the earphones issues many of you are having, but I think the mobile is not smooth (I would expect that a mobile having 8 cores and 2GB of RAM being more responsive, reactive and fluid).

Reading a little bit around, it seems that the ROM available here www . movilesdualsim .com /tema/rom-mod-lenovo-a806-vibeui-2-0-1439-25-09-14-android-4-4-2-por-tiode-y-manowaracero.83100/ works quite well (at least from Spain, it contains GPS optimization from Europe and better translations. It also uses Android 4.4.2 rather than 4.4.0 that comes with the mobile). I had to post the link like this because I am a new user.

First of all I would like to know: has any of you tried this ROM, would you recommend it? If not which ROM do you think is the best for this mobile? Is there any ROM based on Android 5.x available?

Second, I am a complete newbie to building/flashing roms. A few years ago I used some windows program to flash a rom on a tablet, but now I have completely switched to Linux (and have no access to windows computers or virtual machines). I have read that I can use flashboot, and other tools. Is there anybody here that can help me with getting started? (I have been pointed to some guides for Linux and other mobile devices, but I was wondering if you could give me advices related to the A806 as well).

I would like to entirely backup the ROM I actually have (or at least to know it is easy going back in case I need it later), root the mobile and flash a ROM that works, but I have no idea how to do all of this. Possibly if I learn how I would like to try different ROMs.

Thanks a lot in advance to all of you for the help,

Cheers,

Luca

How to enable USB OTG

USB OTG is not supported on this device. I know, it's really sad, but you can enable it. This works only if you have the device rooted.

Hi Luca, I think you're italian just like me, so you can find more about your two questions on androidiani italian forum, searching for "androidiani modding-lenovo-a806".

I installed the spanish ROM yesterday, it works like a charm! With the one which I got with the phone my power consumption was, idle, about 3% per hour (during the night, for example). Tonight the power consumption was les than 1% !!!

So I can suggest to install that ROM, following that guide: you don't need any flashtool, simply:

transfer the ROM compressed files (ROM + Language corrections) to an uSD card;

install mobileuncle tools from PlayStore;

insert in the phone and start TWRP from mobileuncle tool, wiping data etc and then selecting the two compressed files.

Wait...and enjoy!

Hi,

I am a complete Novice, and bought this phone over 6 months ago, but lack of GAPPS and trying to get it on, I gave up, my wifes phone has busted, cracked screen, and since I have this phone I would really like to flash, preferably with a bloat free rom, for her to use.

Am I correct in thinking that if I download a Vibe UI v2 rom, and since the phone comes with Vibe, I can run as update.zip (boot with power vol + & -)?

I have downloaded SP_Flash_Tool_v3.1344.0.212 & SP_Flash_Tool_v5.1348.002 (think they came with the roms) but failed to flash as no scatter file included, so very very confused.
