I've had my phone rooted with CM10.1 since I got it back in December and last week I was messing around with the new nightlies but because of the all the constant reboots and freezes I decided to go back to an earlier verson of CM10.1.
Now my phone will not boot up and stays in the CM loading screen, I tried to get into recovery but I just feel a vibration and the screen stays dark although sometimes it just goes straight to the boot screen and then stays there.
Have I messed up my phone permanently? Any help will be greatly appreciated (I'm desperate). Thank you very much
Edit: I can get into Odin.
Edit2: After a lot of trial and error I managed to get into recovery, wiped data and reflashed CM, thankfully it worked. Although no one responded thank you.
Device is a LG G3 D850, rooted, TWRP installed, stock ROM on 5.0.1
Here's the story: Yesterday I was browsing normally when the device froze up, then shut off. Wouldn't power on with the power button. I had to pull the battery and then it turned on. When the device booted back up, it was running very sluggish. Immediately noticed that the WiFi was constantly trying to turn on with no success (When entering the WiFi menu it only said "WiFi turning on"). Bluetooth would not turn on either. The battery was draining rapidly, about 20% in 30 minutes with no use. GSam Battery Monitor reported that Kernel (OS) had used 95% of the battery. I tried rebooting the phone with no success. Booted into recovery and cleared cache, no success. Couldn't find anything online besides people saying to try a different ROM/Stock rom or that they were told it was a failed motherboard. I tolerated using the phone into the night, but the battery was constantly draining and the phone temperature reported ~98 degrees even without use. The WiFi and Bluetooth never started working. Today, a few hours into the day, the phone shut off again. This time it started boot looping, going from the LG splash screen then the spinning AT&T screen, it would then hang and reboot (constantly boot looping). Battery pulls didnt help. Once or twice, the phone actually booted into the OS. After a minute it would start bootlooping again. I then booted into recovery and performed a factory reset. After the factory reset, the phone still bootlooped. I then booted into recovery and recovered to a previous nandroid backup. The phone booted up afterwards, with the WiFi actually working. After 5 minutes, the WiFi stopped working again and the phone proceeded to start bootlooping. My next attempt was to flash back to Stock ROM, using this method: http://forum.xda-developers.com/att-lg-g3/general/unroot-return-to-factory-stock-att-lg-g3-t2820827. The flash worked successfully, booting into the OS on the setup screen, but instantly started bootlooping again... The bootloop is a little different now, going from LG splash screen > Green android with blue spinning circle in his stomach > AT&T splash screen > then rebooting. I cant even get into TWRP now (When trying to boot into recovery and clicking yes on the default factory reset screen, it just reboots instead of going into TWRP) Im out of options, should I give up and buy a new device, or does somebody have any other suggestions?

Sadly that is because of a hardware issue. Been happening. A lot lately.

Alright, that's what I had read. Just seemed like a software issue so I was hoping for the best. I went ahead and ordered a new device. Im guessing a full motherboard replacement would be required to fix the device?
Recurring Issue
Hello,
The same problem happened to me a few days ago so this is trully a recurring issue.
I also tried to fix my rom by reinstalling it, then tried to install multiple new rom, and finally flashed the original stock rom. I also am stuck on the bootloop issue.
I'm going to contact LG to see if they can do anything to repaire it but my hope are very low.
I'll try to update this message if I find a solution.
Mine just started bootlooping and no wifi and today it just died. Battery pulls didnt work either no power at all. Probably going to switch to the V30 when its released.

It's probably to late but theres another method returning to stock KitKat dont know the link off hand in development forums. Sucks you couldnt try no adb methods. Still have the Phone want to sell it i need a cheap screen ?
I've had some previous experience with custom roms on my old Nexus 6P and thought I would try the same for my mate 9. Unfortunately I've discovered the Mate 9 is not as easy to install custom roms as I thought.
I've tried several things throughout the day and I feel I've accidently overwritten things I shouldn't have but can't remember everything I've done.
It is an Optus branded phone so I believe at the start of the day I had some version of L09C34. I currently have an unlocked boot loader and TWRP installed and would like to flash back to the stock firmware, but seem to be unable to do so. The boot loader is unlocked and when I try flashing extracted parts from fastboot, the phone will reboot, reboot again and sit at erecovery. Unfortunately while I can connect to wifi, no packages are found for recovery.
Additionally I now get this lovely colourful screen in lieu of the logo on initial boot.
Any help would be appreciated.
Okay, so I've managed to unbrick it and install a version of L09C432 and get it working again - thank you to various threads on XDA. I think what I noticed was that someone else had tried the C432 firmware on a C33 model and it worked. Without being able to get hold of the C34 firmware, I tried to flash nougat originally and it worked.
This morning, I've noticed I still have an issue where the touchscreen won't work when the phone is cold (i.e I can't click anything and can't turn alarms off). If I reboot the phone to recovery it's fine, so it leads me to believe its an OS thing. Also, if I give it a few minutes in my pocket, or holding my palm on the screen it then responds. This is the issue I tried to resolve by resetting and trying a different rom but seems I haven't been successful.
Finally, when I first turn the phone on and the screen lights up I see a green background with one blue and one red box. Any ideas what I have messed up there and how to fix it? I'm not too concerned, but it would be a nicety.
Just providing updates in case anyone comes a long with similar issues.
I have now fixed the strange coloured screen on initial power on. I've found the oeminfo for the C432 firmware on another XDA thread and took a backup of what was currently there, restored the C432 version and rebooted. I was presented with the eRecovery and no TWRP. Quick check in fastboot mode showed the phone relocked. I unlocked it again and it booted no issues, however was unsure if the custom rom was still installed as I was presented with the option of an OTA update. Initially my sim card was not recognised, so I had to remove and reinstall it but so far so good.
I've just reflashed my custom rom and will see how I go.
The only potential issue I have outstanding is my touchscreen not working either first thing in the morning, or when the phone is cold - i.e I've gone to the gym and left it sitting in the locker for 2 hours and I can't use the touchscreen when I come back. I can unlock it fine with the finger print reader and the phsyical buttons respond but touches on the screen won't. If the phone is left alone for a few minutes the screen shuts off and turns back on approx every 5 seconds until it becomes responsive. Has anyone seen anything like this before? My googling hasn't lead me to anything helpful.
Hello
I am very frequent with root and roms etc. but i am facing a big problerm with my s7.
i had already rooted it long back and had twrp, worked great for a year.
but suddenly around a month back it started restarting on its own. and at times it would get stuck at the Samsung logo.
i didnt care that much but then it kept on increasing and happened very frequently. the system will boot up and within 5 seconds it will get frozen, and no its not an app coz it happened in Safe Mode also,
also the screen would become hazy, like the tv does when there is no chane, become greyish.
also when i boot in twrp it would get frozen, like during wiping cache or installing, it will just get frozen in between
i tried upgrading to oreo somehow it started but when i restarted it wont start up. it would be stuck at s7 logo.
TWRP still getting frozen also i have tried other versions, no luck,
then i installed resurection rom for s7, it booted up, was working fine but then when i restarted it would not boot up system.
thats the problem i am facing now,
i tried down upgrading to Nougat but now it will say updating system and then erasing, and then it would get stuck wont boot up the system. it will keep restarting and then get frozen.
Literally spent more than 24 hours on this and no luck
please help
Hello, I would like to talk about my Google Pixel 32GB (8.1) that bootloops. Here are the things I know about it:
1. I bought it a while ago off eBay saying it was a bootloop problem. It sounded like a software problem, so I thought, I could fix this. Turns out I was wrong.
2. I can get it into the bootloader screen
3. It occasionally boots up but then freezes and starts looping again. It normally turns on whenever I turn it off for an extended amount of time. When it did turn on the first time, the first thing I did was turn on OEM unlocking but it says "unavailable to carrier locked devices".
4. Also whenever I leave it off for a while, I can get it into recovery mode.
5. I've tried factory resetting the phone but no hope
6. I can't put a recovery OTA on it because Android Pie is waiting to be downloaded. If I try to download that, it takes too long and the phone loops again
I would really appreciate some help with this and thank you in advance for helping me with it. :good:
