Lenovo Tab 2 A7-30 Development Thread

[PGHammer]

Porting from the A7-10F might be doable

this tab has smoe roms on 4pda but have issues in calling and vpn
and TAB 3 is nearlly the same TAB2 but differ in shape

Different SoC as well (there are four PHABLETS in the A7/TAB2 series - A7-30 G/GV/H/HV that use a MT838x SoC - no relation other than ODM to the MT8127).
The TAB3 (unlike the TAB2) shipped with Lollipop; I have no idea if it uses the MT8127 that my TAB2 uses.

There are ROMs for the A7-10F, however, what would it take to port them to the A7-30F? (The sole difference I am aware of is a GPU difference between the A7-10F and A7-30F - the CPU section of each SoC is identical.)

@xinxali I flashed your ROM (CyanogenMod 13) in GC version and it is working. The SIM doesn't work (of course), but I don't know if it's possible to fix the Bluetooth... Maybe it would be easier to fix for GC version. Thanks in advance, greetings. Awesome work

Bricked my Lenovo A7-30DC

Hello there guys!

I recently rooted my Lenovo Tab 2 A7-30DC with Kingoroot and then replaced the root with SuperSu. Everything seemed okay as I cleared my device off bloatware and other manufacturer apps.
Then It prompted me to update the SuperSu library, which then lead to a reboot. The reboot itself left my phone soft-bricked in a boot-loop.
Couldn't fix it , couldn't even load a recovery image from before. Couldn't do anything except apparantly to flash an original ROM. I flashed an "original" A7-30HC ROM (Notice it's a7-30hc not a7-30dc) from since I couldn't find a DC destribution + the devices seemed all the same (Yes , I realize my mistake and that it is all my fault). After successfully flashing , my device turned off immediately and refuses to turn on at all.

I wouldn't be posting a thread here if my phone really looked HARD HARD UNDOABLE BRICKED. Now that I can't turn it on anymore, I can still get it recognized by the computer by pressing all three buttons at the same time.

So my question would be If I flash the correct ROM, do you think it could get fixed.
I tried another distribution A7-30GC I found (cant post links as I am a new-user) and the flash starts and ends with an error:
----------------------------------------------------------------------------------------------
BROM ERROR: S_FT_ENABLE_DRAM_FAIL (4032)

[EMI] Enable DRAM Failed!
[HINT]:
Please check your load matches to your target which is to be downloaded.
-----------------------------------------------------------------------------------------------


I tried fastbooting a recovery.img I had from before installing SuperSu, but it just gets stuck at [waiting for device], even after I hear my tablet is connected to the PC.

I would be so thankful if you guys have any suggestions as to alternatives of what I am already trying, as I really think the tablet is fixable.
Is it possible to just flash any ROM at all and make it at least go back to a bootloop.

Thank you in advance!!!!

Hi mates, i have a problem with my A7-30F, i try to root it and now i have a bootloop.
Now i need the original firmware
First i check my serial number (HGC8UBLY) at the Leonov homepage

This match with the sticker at the back of the device "TAB 2 A7-30F MT:60076.

First i try to root with kingroot, but this doesn't work.
Than i try to flash TWRP 2.8.7.0 by Jemmini, this was failed and now i have bootloop :crying:

Now i try to flash with the SP Flash Tool the firmware, where i found here
[firmwarefile. com/lenovo-a7-30f or here teamandroiders. com/lenovo-stock-rom-download/
But all the firmware is with the MT6582_Android_scatter.txt file but the SP Flash Tool give me a error and says i neet the MT8127_Android_scatter.txt

Anyone know where i become the right file for my device?

 

[Nothreek]

WTF

....It was EXTRA painful for me because the tool I use asks you to select your device resolution and like a dummy, I actually picked 1024x600 (which is the device's resolution in landscape, but not portrait mode.) When the thing finished installing TWRP and booted up, I was locked out of the tablet because the touch elements for twrp to actually restart or even unlock the device ran off the screen making using them impossible. I had to wait seven hours for the battery to finally die before I could access the thing again, (thanks for skipping the reset button on the a7-30F, Lenovo!)

I can't process your logic and reasoning to wait for 7 hrs. If you going to root first and worth than it replace your recovery which for sure void warranty then have the required level of ba*l*ls to do it.should excuse me but You fool! You could have opened the back of your tablet in less than 5 seconds and with nothing more than the tip of your finger! And believe me it left less trace than the traces of root process!

TWRP 2.8.7.0 Recovery for lenovo tab 2 a7 30f

first of all thanks to jemmini for compiling this twrp recovery.
this recovery is based on Android 5.0.1

Download TWRP recovery from here:Google Drive
Download SP Flash Tool from here:Google Drive

i am not writting how to install it [it is easy]
just install it and enjoy.:good:

for rooting just flash super su from recovery.
you can get latest vertion of super su from here:Super SU

 

[cracktech]

Please be aware that this TWRP is only for the F variant and will not work on other variants (HC,H,DC, GC) and you cannot use TWRP for the HC,GC,H,DC variant to install SuperSU through the zip install as it it will dismount the system partition and will not remount it and the result will be "system not install/not found" error. This is the difference between the 2 TWRP version not compatible.

Proper A7-30F recovery has been Recovered

Hi mates, i have a problem with my A7-30F, i try to root it and now i have a bootloop.
Now i need the original firmware
First i check my serial number (HGC8UBLY) at the Leonov homepage

This match with the sticker at the back of the device "TAB 2 A7-30F MT:60076.

First i try to root with kingroot, but this doesn't work.
Than i try to flash TWRP 2.8.7.0 by Jemmini, this was failed and now i have bootloop :crying:

Now i try to flash with the SP Flash Tool the firmware, where i found here
[firmwarefile. com/lenovo-a7-30f or here teamandroiders. com/lenovo-stock-rom-download/
But all the firmware is with the MT6582_Android_scatter.txt file but the SP Flash Tool give me a error and says i neet the MT8127_Android_scatter.txt

Anyone know where i become the right file for my device?

I am attaching the proper recovery to this post (it was in another thread).

You DO need the MT8127 scatter when using SPFlash Tool - instead, I used Rashr (the rooted-device version) to flash it. The MT6582 is used in the PHABLET (GV/HV) version); the Wi-fi only version uses the MT8127 processor.

hey @alkaA! i had the same problem and i looked everywhere for the proper scatter and files. I found them here: https://malaysianandroidsupport.blogspot.my/2015/06/tab-2-a7-30-7inch-3g-calldata-h-hc-my.html and they worked fine. my tablet was dead dead and i had to take the battery out and flash it with no battery and then reinsert battery and now it works fine.

@cracktech thank you SO much for linking to the proper files for the A7-30F variant. i must have download 10 different ROMS and scatter files and none of them would even load into the SPFlashTool or if they did, they would say it was the wrong chip. i was about to toss this tablet until i found your links and finally the correct ROM and scatter AND a bonus of proper TWRP recovery. now my tablet is back and working.

BOOT LOCK

According to a thread on the lenovo community... the device has a mediatek proceesor, which can be flashed without unlocking anything using their SP flash tool. Only downside is any custom roms would have to be built for mediatek and using a "scatter" file.

Thread: forums.lenovo.com/t5/Lenovo-Android-based-Tablets/how-to-unlock-the-Lenovo-A3000-bootloader/m-p/1588718/
Stock Rom: androidxda.com/download-lenovo-stock-rom-models
Flash Instructions: androidxda.com/flash-stock-rom-using-smart-phone-flash-tool

The rom's source is also available on the Lenovo support site.

Unfortunately, I'm not expert at anything to make anything happen with this information.

---------- Post added at 08:48 PM ---------- Previous post was at 08:41 PM ----------

Then again, all that may have nothing to do with the A3300, since it's all based on the A3000... but same processor type? doesn't seem like mediatek has any info on their site about it either.

FYI ALL MTK SoC devices are not "boot locked" unlesss the Manufacturer themselves has managed to boot locked (which I am so far not aware of) Customs ROM can be build to be "installed" from TWRP/CWM/ ect. As developer when you want to modify/upgrade the bootloader to a none existing upgrade version (like from KitKat to Lollipop or Marshmallow) you should know what to do and try on your bench on your specific model. No ALL Mediatek SoC are not "bootlocked" never heard of it in MTK world.
The US based Lenovo community forum is a waste of time was there. The best Lenovo support site is the Russian Lenovo site where I get my firmware for S939,A369i, Tab A8-A5500, Tab A7-30, A880, A889 (all of which I owned) , the A3300 is available from there : http://lenovo-forums.ru/talks/

Glad I could help out!! I am moving on to Lenovo Phab2 Plus (not Pro because I like MTK SoC)
But this is an advise to all the A7-30XX users out here that. I recommend it to be rooted because in all the firmware version, the bloatware folders resides within the system folder. So if you think that by uninstalling the bloatwares they are gone , you are dead wrong! They are occupying nearly 300Mb of the precious system storage and still there. This what you do! Unisntall all the bloatwares , root it then go inside /system/appjar/ folder and delete all the "apk" inside that folder (after uninstalling them first!).
Your Google system app will be updated and they will occupy your meagre data storage area whereas they should reside in the /system/app and system/priv-app/ folder and thus free up the space. You will have to MANUALLY copy individual Google app back into /system/app/ folder.
If you use Root Explorer you will be able to see the icon of each individual app. In the /data/ap/ folder they will be named as example "com.google.android.googlequicksearchbox-1" folder wthin which resides "base.apk" and "lib" sub folder all the google apps will be named "com.google.android.XXXXXXX-1/2" . The "googlequicksearchbox" is actually your Google Apps but in the system it named as "Velvet.apk" so you have to COPY it somewhere in your internal sdcard then rename the "base.apk" to "Velvet.apk" (if confused just look at the icon) then move the whole "Velvet.apk and "lib" sub folder to the correct location (this case it will be in the "priv-app") Apps like Gmail/Maps/GooglePlus/ will be in the /system/app" folder. After you have done this manual pushing back of apps immediately reboot.

About SpFlashTool for Tab that usually cannot remove battery we use SP FlashTool verion "5.xx.yy." select with battery or "auto" and DA/AllChecksum must be ticked in the option. NO need to remove battery BUT just ensure that that the Tab/Phone is totally OFF and not in sleep mode. Press power button till you feel vibration. Then proceed with the flashing process as usual.
