Hello there
I'm using an I9300 with TWRP and CM12.1. I also have a NANDROID backup sitting on my PC that was made through CWM (which the phone used to have before TWRP).
I tried to factory reset my I9300 running from inside the ROM rather than re-flashing it, and now my device is stuck in TWRP bootloop. I cannot access either the ROM or TWRP, the only thing I can access is download mode. Can anyone please help me resolve the issue? I haven't used Odin since rooting the device years ago and I can't find any guide for this specific procedure so I'm kinda lost.
Follow the guide in general forum, sticky thread on returning to stock.
Hey guys,
I just tried to root my Acer Iconia One 10 B3-A20 (not A3-A20!!!) with Kingsroot and it kinda worked. I could grant root access to apps and modify some stuff, but unfortunately after debloating something went wrong and my tablet is in a bootloop. I performed a hardreset so I could start from the beginning. After completing the android set up I was thrown instantly to another bootloop. After some researches I tried to do the android set up but without the last step and I installed another launcher via playstore and email. Afterwards I could start and do whatever I want to do. Unluckily I'm again in an bootloop after I did a restart. I can't enter the android set up procedure anymore and can't install any apps from the playstore.
Right now I can do following:
- I can access the download mode and try to do something with adb, BUT I'm unauthorized and can't tick the USB debugging think as you can imagine
- Try to flash something via recovery, but untill now I could not flash anything
Does anybody have a suggestion? Stock recovery is still accessible, but somehow I can't flash anything.
Hope anybody can help me out.
Thanks in advance. Best Regards,
GerasVille
EDIT: It's solved and the thread can be closed.
Thanks to Shreps I could flash the stock firmware via stock recovery. Here is his post.

Hello, need help whith
I also had problems with kingroot, and decided to reset tablet "factory default".
The tablet would not start, loop on the logo. I saw this post, and download the "OS" official Acer ICONIA ACER ONE 10 B3-A20 and install it from a sd card and stock recovery.
Everything went well, the tablet starts asking me choose language, wifi network and login with google account I had before the reset. And here is the problem: I was not which account google it had before the reset, the tablet is 2nd hand and do not know how to solve this.
there any way you can skip this protection?
It is possible to flash a rom with spflash clean and able to put a new google account?
I'm bored to seek and find nothing.
Thanks in advance

Hey guys,
My phone got stuck while factory reset was going on. Ever since then I have tried almost everything but nothing seems to work.
My device was rooted and had the twrp recovery on tried to install Stock ROM file using nexus root toolkit, that didn't work, tried to install the stock ROM using the twrp recovery (via otg) that didn't work.
E: can't mount data, system, sad card .... The list goes on. So I read about [HOWTO] [GUIDE] Repairing corrupted /data partition by cadbomb, and followed step by step instructions ( use adb commands while on philz recovery) to try and fix the partition problems. But that didn't work too .... So I really need your help guys. Make sure you break it down to simple step by step instructions because I am a complete newbie to this stuff
Thanx in advance
