Did you have pad rooted? Also, did you have a recovery installed at all?
Can you answer the above and maybe someone can help.

Cal, my pad was rooted, but after running those, I had not on recovery (tried adb reboot recovery, blank black screen after LG logo again). The weird thing is that I think the Android had gone up, as I can adb to it even in a blank screen. However, it looks like a bricked system...

Phone is stuck on teamwin screen flashing on and off.

I cannot use the hardware buttons any longer to even get into fastboot mode. I tried to insert a new TWRP theme, named it ui.zip, place it in the theme folder, then rebooted the phone and now it will not even go into recovery, fastboot mode, nor turn on. Anybody have any suggestions on how to get through to the recovery. I guess I locked up the recovery, and can no longer boot my phone to even be able to delete that ui.zip file from the theme folder under TWRP.
OK, now I managed to get it into fastboot mode. But that is it.
Can I extract a file from the phone in fastboot mode?
Thanks,

Well, I finally figured it out. I'll add an explanation on this whole deal after I get off work. Just in case anybody else runs into the same problem, maybe my little routine will help someone else.

Next time you loop, vol up and power for 10 seconds with phone Unplugged, then vol down and power to go to boot loader
If for some reason it doesn't restart put the phone close to a bright light
Similar problem
Hi. I am on a Kindle Fire HD 7 and just got cynogeanmod 12. I was going through settings when device got laggy. And somehow the device thought I wanted factory reset so thats what it did. My Kindle Rebooted and now I get a screen that says "teamwin" and every 2 secs. the screen flashes. None of the tips using buttons worked. It can only turn on and off. I need assistance in finding a way to get this back to stock(from there I can re-root and do the process again to get back cynogeanmod).
Thanks,

First, this is the M8 forum, not the Kindle forum. However, I actually can help you with that.
Most stock recoveries seem to have a problem with doing factory resets. Flash the stock recovery for your device, let it perform the factory reset, boot back into the OS (to make sure it worked), then reflash your custom recovery.

Tank you for this quick reply :good: . I will try to get back into my stock recovery but if it is on my device, how will I access this on my computer and force flash it on my tablet. I only need help making the tablet responsive/workable. Once this is done I should be able to figure out the rest.
Thanks

Stuck on CM restart screen

Hi all,
I just rooted my G Pad on 4.2.2 and installed CWM 6.0.5.1, and then flashed the latest CM12 from their website. Now I'm stuck on the blue android loading screen. I've tried to get back into recovery, but I can't seem to boot into it with the key presses. It will show me the factory reset screen and then just tries to restart again. Any ideas on how to proceed from here?
EDIT: Was able to get into download mode and reflash stock 4.2. nothing to see here

Did a reset to factory on my tablet, now in TWRP bootloop, please help! [SOLVED]

All I did was do a reset to factory settings on my tablet, it rebooted and it's now in a TWRP bootloop?
I see the TWRP logo come on and then the screen goes black and then the TWRP logo comes on again?
Please help! I have no idea what to do???
I searched all over Google but couldn't find anything that worked?
This has happened to a lot of people: http://forums.androidcentral.com/sa...p-after-factory-reset-cyanogenmod-12-1-a.html
So, I'm going to make this warning REALLY BIG so this doesn't happen to you as well:
If you are running CyanogenMod 12.1 and TWRP recovery, then DO NOT ever do a FACTORY RESET.
You will break your tablet.
HOW TO FIX:
The only way I was able to fix this was to use Odin and put the stock firmware back onto the tablet.
Hello, can anyone help me, where to download the stock firmware.
I think, I'm having a same problem here. My boot screen are blank, right after the Title screen

TWRP/CWM Recovery starts Boot Loop

Hi,
Trying to root the following unlocked phone of mine..
Current Mobile version : HTC Desire 816 A5_DWG "India" - Dual Sim
Software version : 3.14.720.1 / Marshmallow 6.0 with HTC Sense 7.0
I flashed 5/6 different TWRP/CWM versions via ADB/Fastboot as the phone is accessible... but when I try to enter the Recovery, in CWM the screen goes blank while with TWRP, the Phone actually starts an infinite boot loop with "Entering Recovery" -> Down - > "Entering Recovery".. the connected phone is not available to ADB/Fastboot during this time... and I have to wait for Phone battery to exhaust, so I can start the phone in Bootloader and restart as normal.. Can anyone point me to the actual TWRP/CWM or any other Recovery image for the model & version? The phone has no external card, not sure if that could be a limitation in the process? Also do I need to unlock the phone every time I put Stock Recovery back?
thanks in advance
I just stumbled upon your exact problem after flashing twrp-3.1.0-0-a5.img
I flashed the oldest version of TWRP I can find on twrp.me (twrp-2.7.1.0-a5.img) and now it's all okay.
BTW, while the phone looping the "entering recovery mode" process, you can hold both Up volume and Power button to boot normally instead of waiting for the battery to drain exhaust.

Thanks a lot for both the pointers... TWRP, the old version did work and also the up volume+ power is working fine.. But after getting into TWRP and wiping partitions & data, the system is now booting to always hung state (stuck on white HTC boot screen).. Can get to bootloader/fast boot, but ADB doesnt detect the device now.... When I enter TWRP, the phone is detected in adb in the "recovery mode" , but fastboot doesnt work.. How can the stock recovery/other recovery be installed at this hung state..
thanks in advance
If you have a ROM (or a backup image), you can flash it when you're in recovery mode; I don't think you need ADB to do that?
And also, what is the cid of your phone and what image did you use?
Sorry for the delay.

I have the same problem with latest version 3.1.0-0, though older versions working fine. Could you manage to get the latest version working? or the image file has bug?

It's quite difficult to find a suitable image for my phone so I ended up using the old version of TWRP. I don't really know if it's a bug in the image file or TWRP itself.
But then again, why do you want to use the latest version of TWRP?

Previous versions of TWRP were not able to decrypt/ access my 'adopted SD-card' (merged with internal memory).
I was hoping , the latest version would be able to do that.

Help!!! No root no recovery in custom rom

HI i flashed this aosp rom
https://forum.xda-developers.com/lg-g3/orig-development/rom-pixel-g3-aosp-t3571499
i flashed the rom, the gapps file and mr bump, and figured i would get root later.
After setting up my D855 i decided to get root, so i pressed to reboot to recovery and there was none!!! the phone kept "recovery bootloopin" and showing the tre triangle with android logo for a split second, then the screen turned black-off then egain and again, untill i pulled the battery and it booted normally.
i tried kingroot and similar options but nothing worked. I tried to adb flash recovery but it was my first time with adb and could make it work. PLease HELP!!!

I would just reflash the kdz and start again, it would be way easier that way if you have the time.
