[Q] Thunderbolt stuck on bootloader screen. - General Questions and Answers

I rooted my TB the other day and everything went well. I've been using it with no problems until now. I wake up this morning and it's stuck on the bootloader or fastboot screen and no option that I choose allows my phone to boot up normally. Any help with this matter would be greatly appreciated. Thanks.

Similar Issue
I've had the same thing happen with mine, except after multiple boot loader reboots I can eventually get the phone to boot. Eventually it will display the message "Shutting Down" The longest it's worked before rebooting is 30 minutes, but I've not allowed the VZ update to go through. Any suggestions? Thinking of trying to flash a rom.

[Q] Deactivated Nexus S 4G stuck on unlock bootloader screen

Ok, so had it unlocked, but running stock. Ran fine, then one day it stopped working and got stuck in a boot loop on the google screen. Managed to get it into CWM and then wiped, after lots of tries, and back to CM7 and unlocked. Then backed it out to stock and locked the bootloader(was planning on giving it to a friend who doesn't like to play with phones like that). But now it gets stuck on the google screen. Can get to fastboot, but if I do fastboot oem unlock it just has "..." and holds for hours(until I manually stop it) and then says it failed too many links. Can't get it unlocked, can't get it to boot into anything usable(either fastboot or the google screen and no further) and I'd really like to turn it back into a tablet for the kids to use since I've moved on. ADB devices shows error device not found but fastboot devices shows the serial number. I just really need to know how to unlock it so I can get it back and running. I think what screwed it up was I flashed it back to the way it came locked bootloader and then it said there was a OTA update, I said ok, downloaded it and when it rebooted it wouldn't go past google screen or past fastboot screen. If I try and do the recovery I get the triangle with exclamation point(yellow) and if I hit the power button a few times it tries to reboot and hangs. And yes, when I do the unlock the screen comes up, I move it to yes, hit power and then it freezes. Thoughts? Thanks in advance.
Ever Fix This?
Did you ever get this figured out? This is where I'm at after hours and hours to get to this point.

Nexus stuck at update screen (droid with polyhedron)

My Nexus 5 seems to get stuck at the update screen (the standing green android with the spinning polyhedron) after flashing to stock(+unroot) with softbrick/bootloop checked. The flash completed without error. I've left it at this screen for over an hour and not only does it not progress it doesn't even get to the progress bar at the bottom.
This afternoon my (unrooted, bootlocked, stock) N5 turned itself off 3 times while on the charger. Powered back on and then would find it turned off 20 or so minutes later when I checked it again. After the third time it booted to the "Google" screen and would go no further. I tried a hard reset but it gave an error. So I plugged it into my laptop and fired up Wug's NRT, unlocked the bootloader (at which point it got stuck at the same update screen described above for around an hour). I held power till it went off, booted back into bootloader (which showed as unlocked) and performed the flash to stock(+unroot) with softbrick/bootloop checked and ended up at the update animation again. Any thoughts other than RMA?
****Edit: Finally got the phone to boot after fastboot booting twrp. Was able to to wipe the phone (after multiple attemps blocked by can not mount storage/cache/etc/etc errors). Flashed 4.4 and the phone now boots to android BUT radio is non-functional (no signal despite being in my normal coverage area), any attempt to add an APN causes a hard reboot (had to go through all the setup screens again). Additionally, the phone won't turn off, even hard power downs (holding the button for 30 secs) lead to an immediate reboot. Still RMAing but I was able to relock the bootloader.
You really shouldn't RMA a phone after messing it up yourself by using a toolkit when you didn't know what you were doing.
Flash the factory images manually. That should get your phone up and running again.

Performed a manual flash with the exact same results. There is apparently something wrong with the hardware (which may explain why it was turning itself off and then wouldn't boot past the google logo.

Yep, I would agree.

LG G3 stuck in bootloop, even after flashing stock ROM

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.

Nexus 5x google bootloop, recovery won't get past Google screen either (strange)

I was in snapchat when all of a sudden my nexus 5x totally froze and rebooted (which is normal considering how much snapchat sucks.)
I saw the warning about my bootloader being unlocked which was normal and it went to the Google screen, where it sat for about 5 minutes. Normally in every previous bootloop I've had in the past, the boot animation just loops forever and ever. I force shut it off and tried booting it up again and this time on the Google screen the phone totally shut off and restarted showing me the warning about my bootloader. I tried the recovery, but got the same results. So, I went home and plugged it in thinking maybe that would help but it still was shutting off and rebooting. It never got to the boot animation. I had all the adb and fastboot drivers so I just decided to flash the factory image. It flashed fine, and sadly the problem was still there. I'm so stuck, I can't get into the recovery to do anything and there's only so much that you can do over fastboot. I've found that if I press the power button every couple seconds while the Google screen is still showing and it doesn't reboot but the Google logo won't leave for the boot animation.
Seriously guys, please just give me any of your ideas.

Phone won't complete after stock flash

My father-in-law's S6 was rebooting right after the menu screen came up. After trying numerous things which wouldn't work (still had varying boot loops) like getting into the recovery mode and doing a factory wipe, I decided to use Odin and flash the base stock Android nougat on this (it had the one verizon security patch after that, so should be no issue doing this).
That went okay and it rebooted and got all the way to "Android is starting" which you see after a firmware upgrade. But I didn't realize the battery had run down through all this so it died at this stage. So it was taking a charge now, so let it charge overnight and give it another run.
Got up today, tried to start it...back to the boot loop. So I figured I'd flash stock again with Odin (can always get back to that mode).
It completes successfully and then after the reboot at about 32% jumps to "erasing" and then the boot loop again.
Got into recovery mode once and wiped cache (pointless at this point, but whatever) and did factory reset there, then boot to bootloader. Got all the way to the verizon screen...and then boot loop again.
Is this phone just done? The only thing I can consistently get to is Odin mode. I tried the stock reflash a couple more times and keep ending up in a boot loop and it doesn't even get past the "custom" screen now. And I can't even actually get it to shutdown for that matter. I can get to the battery pull mode but if I try to power off from there, I just get the black screen with the blue light.
And, to make matters even worse, now on restart, it brings up the blue system update screen for a second, then jumps over to the no command screen, sits there for a second, then reboots again. I think I've somehow managed to even blow the recovery menu but this has all been stock and never had any custom firmware or root.
Any help/suggestions would be greatly appreciated!
