[Q] Bricked A2107A-F Tablet

Hello,
I bought my wife one of these tablets for her birthday. It was running great, decided to root it so that I can uninstall the bloatware that was eating this tablet up after using it for a week. Uninstalled all the happy lenovo stock softs, everything is all good... Well I decided to put JB on this tablet after root stock rom was running great. I made a backup, but somehow I completely crashed the file system, and I can get into recovery VOL+ VOL- POWER, while usb plugged in. I had a hell of a time getting drivers install in windows, and also debian. Drivers are like NOT installing properly, or it will install properly in windows, then I have an error on another device etc. I cannot get past the lenovo splash screen that does nothing, and the only way I can get adb devices to recognize the device, is when it is in splash screen mode on lenovo, but NO other adb commands will work! adb shell will simply freeze terminal or dos. It will not read micro SD card when I boot recovery, linux or windows has no idea how to even read my device when I plug it in while in recovery, im about to buy her a new one. I have googled and googled for days and hours for a fix on this. If you need detail, please ask, and I will gladly give you info. Please help, my wife is super pissed.
Thanks!!!

hey have you managed to solve this problem? I think I have the same issue as you. my tablet just doesn't want to boot normally even after reloading roms.

[Q]Phone can't get recognized by pc, download mode available

Hi,
yesterday I got d802 phone to fix it. First the phone was stuck at LG screen with certification error which I fixed. Phone was recognized by PC and i installed twrp on phone. I tried everything (i guess) and now phone is stuck at LG screen and it doesnt move. Now i cannot go back to twrp recovery but i can get to download mode but phone isn't recognized by pc so i cannot flash kdz file to phone. I'm really stuck at this point. Is this real hard brick or is there any way to fix it? Any ideas what should i do or something i can try?
I tried to plug phone in other computers and it's the same thing. My laptop recognized that something is plugged in once but it didn't know what was it so by now. Somehow from time to time phone doesn't go to download mode but it goes in hardware key control mode.
Hope someone can help...

So far i manged to get to recovery mode but adb sideload isn't working. I tried to wipe everything and that didn't help. As we speak factory reset is in progress but I think it's stuck on formatting cache. I hope I'll be able to get the phone recognized in download mode. Any suggestions are appreciated

I have made some progress. ADB is working now and i pushed cyanogenmod and on installation it says that it cannot mount data and cache. I think that main problem is that phone isn't rooted and now I'm trying to root phone via adb. If someone knows anyway to do this that would be great

Device not recognized/malfunctioned

Hello Guys! . I've got an issue on my hands, and I'm not really sure how can I solve it. I installed a new ROM, through TWRP recovery. After flashing, I tried to access the recovery, but the the phone started to bootloop, and sometimes it showed a greenish welcome screen. After a few bootloops, the phone started normally, entering the system. So, no recovery on it. Right now, after I tried to access the recovery a few times, the phone is blocked on bootloop . No access to files, no access to system, and no access to recovery also. Can you please advise what can I do furthermore?
Also, very important to mention is that the computer doesn;t seem to see the phone, I tried to another PC, the same thing. It says (in both computer cases) " USB device not recognised".
Is there any way to force somehow fastboot mode on the phone? ...
I really need some helping ideas, since I'm out....
Thank you!

Nexus 4 stuck in Bootloop

Hi Guys,
I updated my N4 to CM13 with Android 6 via TWRP about two months ago and everything was fine. Today I accidentally deleted the System Partition through the TWRP Bootloader Application and the Phone logically does not boot up properly, it just freezes as the Google logo comes on.
The problem I am facing now is that i cant simply overwrite the OS with a fresh one, because my Computer does not recognize the Phone anymore.
When you go into the Bootloader Windows makes the typical sound effect but the phone does not show up as an external storage.
So I entered the printers and devices menu and it gives me this information : Model: Android Category: unknown
It is conspicious that the computer only recognises the phone when I enter the Bootloader by pressing power und vol down or when I am in the TWRP application.
The data on the phone is not important and I backed everything up, but I would really appreciate it when someone could help me to bring my phone to life again.
:good:
If I didnt express myself detailed enough just ask my everything.

Does fastboot recognize the device when in bootloader and/or does adb recognize the device in recovery? If so, it's easy to fix.

Hard Brick / Soft Brick ? Help

Hi all,
A strange thing happen to me, my Zuk Z1 ran out of battery and I've put it to charge and when I boot it up again it kept boot looping.
My Zuk Z1 is the international version and I have tried all of the below solutions
Clear all caches and media - No luck
Use QFIL with original rom - No luck keeps boot looping and most of the times gives an error at the very end of the QFIL ( Download Failed QDloader .... )
Used QFIL with ZUI rom - Works but most of the functions don't work, no wifi, bluethooh and so on
Erased sdl1 with fastboot ( that made the phone to seem dead, had to open it and remove the battery in order to be able to install QFIL rom again )
ADB sideload, stops at 47% everytime and the phone reboots and keeps doing the boot loop.
I can get ADB and Fastboot working but I'm running out of ideas!
Also I was thinking on rooting the phone to allow me to install Cyanogenmod to see if it works but don't know how to achieve this, Kingroot needs internet and I have no way of getting it to work.
Any idea would be very welcome !
Thanks
UPDATE:
I was able to flash TWRP and CYANOGENMOD 13, it boots but its the same as in ZUI, no wifi or bluetooth, I'm guessing it was the motherboard that fried !? The mac address displayed on the WLAN is 02:00:00:00:00:00 and i've tried several options in developer mode which didn't work.
