Anyone know how I can unbrick the model with number 59410286 with a "MTK 8121 QC" CPU? It's labeled "A7-40 A3500-FL", so I followed the guide here, not noticing the CPU is different, and by that I bricked it.
Depends how bricked it is? Can you access recovery? Do you have backup? What exactly is not working and what you did to brick it? The russian lenovo forums might have right rom and stuff for your model.
From recovery you need to flash recovery flashable zips. Image/bin flashs are generally via pc/Windows with some program/tool like in this guide.
I used one of the russian roms and now it's working again.
Thanks for helping.It was again for the wrong CPU, and flash tool showed an error message. Maybe it was just stuck somewhere.
i have the exact same device as you , it's bricked but i have access to TWRP to bring it back to life , can you describe how did you did it in a kind of step by step . it would be awsome or even if you can make a rom backup from your now NOTbrickedowner lenovo and .zip to me ? I'm happy for youI used one of the russian roms and now it's working again.

Sweet taste of achievment
SP Flash tool app, latest release
original SCATTER file ROM and auto-install USB drivers.
Before do this, check your model - A7-40 ( A3500-FL ), A7-50 ( A3500-F, A3500-H, A3500-HV ) in my case A7-50, A3500-F
If you reflash the tablet with incorrect ROM you can damage it. but if you are here you have past that concern, right ?
1. Download the ROM A3500-F_A442_01_34_140904_ROW This is a .RAR containing all that is mentioned in these instructions (*)
2. (**) my device turns ON and freezes or i boot in TWRP. can't switch off when needed and the battery is not removable. it was my biggest challenge as using the flash tool you need to turn off and on a few times, so FIND THE RESET HOLE that you can RESET using a paper-clip (in my case isvery close to the SD card is inserted.
3. Install drivers - i have a .bat that makes the job very easy
4. Start Device manager to control the driver installation.
------
5. Start SP_Flash_Tool.exe
6. Press "Scatter_loading" and load "MT6582_Android_scatter.txt (*)
7. Press "Download", SP_Flash_Tool will load necessery files.
8. Switch off the tablet. (**)
9. Press and hold the Volume Down button until you connect the micro USB cable.
10. Windows will start installing Preloader USB VCOM (Port X).
11. don't worry if the tablet starts or shoes charging symbol .
12. When Windows finished with the installation, reconnect the tablet again while press and hold the Volume down button (the tablet must be switched off). (**)All this things do take time be patient, use good quality usb cables and NEVER break the connection .
All i gave you is words , check some videos about the SP Flash tool...
All i can say is that after 3 months of mute , when i turned my tablet on and i heard the lenovo booting sound it was AMAZING but, it took 11 minutes in is first boot. all the times that i was tempted to grab 80 quid and buy a new one, i'm just so glad i didn't.
Like i said i have loads of info on most lenovo mobile devices, but (*)..... so, contact me if you need !
thank you all, but now i'm going to leave this old reliable Ubuntu dual boot win7 for a few days and explore the new toy toshiba satellite L50 and the pre installed Win 10.
Peace !

Hello, I rooted successfully my tablet and thank you for the tutorial.
Is there any custom rom for this tablet? The Cyanogenmod doesn't have anything about.
Is there any custom rom for this tablet? The Cyanogenmod doesn't have anything about.
After following this guide, is it possible to flash TWRP recovery from within CWM recovery?
The only custom rom I was able to find is a clean KitKat port (probably AOSP) here: http://www.needrom.com/download/a70-40-a3500fl/Hello, I rooted successfully my tablet and thank you for the tutorial.

My son's tablet became unstable and after several attempts of fixing it, I decided to install ROM from scratch so I followed this guide and links and did it with original ROM and updates OTA., or more like Lenovo smart asistant.
Everything works fine now and thank you! for that!
There is good info here too (and surroundings... )

Mirrou,
Can you get in recovery?
If not try to flash recovery. I prefer CWM on A3500FL.
Then download Custom ROM ( I prefer RR 5.7.4) and install. During installation it give message - detected file system ext4 bla bla - but leave it for ~ 5-10 min and it will finish with message script finished succesfully - 1.
After that gaps should be flashed if you want to have Play store. http://opengapps.org/ there select arm, android 6.0 and type. I prefer pico.
So prepare sd card with those 2 files on it - rom and gaps and enjoy.
