I was in the same situation tonight. I have the AT&T variant. I found the answer on droidforum(dot)net by member HARVESTERX:
"OK, so you're booting into fastboot and trying to ADB from there? Have you tied booting into recovery (since you said that you were able to successfully flash one)? I'm on the Verizon G2 so not too familiar if it's the same on your model, but to get into recovery I power on the phone by pressing and bring the power and volume - buttons at the same time. After seeing the LG logo I have to release both buttons and press and hold power and volume - once more which takes me into the factory reset mode. From here press the power button a few times as if I'm doing a factory reset and it loads up TWRP from there.
This has saved my ass once already because I wiped my internal storage mount by accident and deleted all my backups and ROMs, so I used a Windows XP computer (can't get any other version of Windows to recognize my device...well I know how but it involves more time than I have at the computer as it's not mine) and pushed a ROM over using ADB that way. It's been a few days so hopefully you've fixed the issue... "
This method put me into TWRP and I was able to RESTORE my phone to the backup I had done earlier this evening.
I hope this helps!

[Q] [XOOM 2/MZ608-16] Won't boot/charge / bricked

Hello everyone.
I searched the whole forum and found similar threads with kinda the same problem - but no solution worked for me (or aswell none was stated).
My problem is that my Xoom 2 ME (MZ608-16) (Android 4.0.4) won't turn back on, doesn't light up the LED when charging and seems to be fully bricked.
I also tried to do those button-combo tricks but it had no use. I held those combos several times for a longer period.
But what I can tell is that the screen does a small short flash as if it would boot after holding the buttons POWER/LOCK + SOUND UP for a short time.
Holding those buttons even longer after the first not-easy-to-notice flash it rapidly happens again and again.
What caused this trouble was that I tried to flash the firmware after rooting.
First I stocked at a screen showed that some flash didn't worked out well (looks like fastboot mode).. that happend after trying to flash the recovery to do a proper backup before to do the-stuff-i-wished-to-do. It showes up every boot. Normal boot could be inizialized even though after entering the "control menu" via pressing VOL UP + VOL DOWN + POWER/LOCK on the same time and releae it.
After that I wished to fix it via flashing the whole firmware in hope the message would go away.. troublesome was that I used the wrong firmware for another Model than the MZ608.
And now I'm stocked.
You all helped me already a few times without me registering.
Now I hope you can help me ones again.
Thank you very much in advance.
Greetings

Edit 2013-05-08: Still no changes.
I request further help
You can put phone back into fastboot using factory cable method - see here http://forum.xda-developers.com/showthread.php?t=1077414
If the phone is bricked then you need to use omapflash to flash fastboot and then the image - see here http://forum.xda-developers.com/showthread.php?t=1242330

[Q] Half-Bricked G2

Hey Guys!
As I finally gave up looking through hundreds of comments and several different threads I will try it this way...
I am not new into flashing, as I messed around a lot with my Galaxy S2 and especially with my HTC HD2 (loved that thing!)
Now I wanted to flash my G2 too (after 2 years with stock rom), but something went wrong. I can neither enter download- nor recoverymode. But it works as usual, even after resetting it to factory state.
It just showed me the boot security error then I was able to force restart it by holding Power + VolUP and it was reset to the state where I bought it.
I rooted with ioroot, then I tried to put CWM on it (CWM-Official- TOUCH-6.0.4.4(D802)), which I already figured out that it wasn't the best idea, since everybody seems to use TWRP on his G2. But I didn't know a thing about TWRP and I was used to use CWM for flashing, so I tried it.
Then I read that there is a problem with stock ROMS and ADB root, because the CMD showed me an error saying that "adb cannot run as root in production builds". By doing some research on the Internet I figured out that something went incredibly wrong. ( I also forgot about the bootloader.. it was a long time since I flashed a phone )
My Phone is a open LG G2 D802, KOT49I.D80220g, 32 GB.
I have already messed around with this for some time, but it wasn't successful since the device wasn't shown in the ls command, I assume it's because it's still recognized by Ubuntu as an MTP? (I read to page
http://forum.xda-developers.com/showthread.php?t=2582142
But every other solution I have found requires download mode, which I'm not able to enter (Not by pressing Power + VolUP (or Vol down) until LG Logo, then release and press again, nor by holding volUP while plugging in the USB cable (of course the device was powered off))
Does anybody have some advices?
I hope I gave all information you need.
Kind Regards
Lukas
Is your device rooted?
Yes it is.
I think you might have to short the chip to force it in qhsusb mode and flash laf.img,aboot.img and boot.img

New/Stock Oneplus Two, unable to boot into recovery

Hey all, completely new to this forum and my Oneplus Two that I've had for a little over two weeks.
I recently got a OTA update for Oxygen 2.2.0 but I can't seem to install it. Everytime I download it and click the "install" option, the phone reboots (probably to go to recovery) but after a very brief splash screen and a vibration, it vibrates again and displays the standard boot splash screen, boots into the OS and offers me to download the update again.
I've done a little troubleshooting in the past two-three days and from what I understand, the phone doesn't seem to be able to boot into recovery or fastboot. I've enabled the advanced options in the "reboot" menu and when selecting "recovery" the phone reboots and does the same behavior described above. I tried powering off the phone and booting with the volume up button pressed (while pressing power) and the phone boots and displays a "Fastboot Mode" splash screen but it seems to hang there forever until I actually shut it off again and power it back on. Also, I've tried booting it into recovery from ADB, connected to my PC and I get the same behavior: brief splash screen with a vibrate and then the phone seems to reboot again normally.
I haven't tampered with the phone yet, it is brand new out of the box, not rooted and nothing other than simply installing a few games, Nova Launcher, changing the wallpaper and using it as you would normally use your phone.
Anyone has an idea how I could actually get the Recovery functioning on this phone?
Best regards and thanks in advance for any help!

That is the norm for fastboot, it doesn't go past that screen.
It may not make a difference, did you try to boot to recovery via Power+Volume Down buttons?
Greetings Khaos64,
Yes, I've tried booting with Vol-Down+Power but the phone does not start.
With volume-up+power, I get the Fastboot splash screen but the phone does not respond to any input.
I tried selecting "bootloader" from the reboot menu but I get the same thing: Reboots and after a second, the phone reboots again normaly and into OxygenOS.
Is there a way to verify if the bootloader or recovery is corrupt and maybe reflash the stock recovery onto the phone?
Thanks for your input!
You may just want to go straight to oneplus support since everything is stock and only 2 weeks they should be able to get you updated or replace it.
If you'd like to be more hands on... maybe something below can help.
So your phone isn't recognized/no commands acceptred from your computer when booted to fastboot?
Such as unlocking your bootloader and booting into twrp... "fastboot boot yourfilename.img" or maybe flashing it.
Make sure OEM unlocking is selected in Developer options.
If you can't do that then this may not work but is worth a shot.

I did try to contact Oneplus for support but I am not the one who purchased the phone. Long story short, it was a gift from my girlfriend that she bought off of someone. The phone was new in box and was a warranty replacement. I would have to contact the seller and go trough him for support unfortunately.
Thanks for the different suggestions!, I will fiddle around with it this afternoon while the kids are having their mid-day nap and I'll get back with the results
Thanks again for the help, it's greatly appreciated!
Hello,
I eventually started fiddling around with fasboot and tried unlocking the bootloader. This sent the phone into a bootloop where it would try to boot into recovery and reboot right away.
I found an article on how to restore the phone to Oxygen 2.1.1. It would wipe user data but I did it anyway and it actually did restore the phone and now I have a worling recovery.
Here is a link to the guide I used:

HI there,
I am having the exact same issue with my oneplus 2. Unfortunately i know almost nothing regarding these android thingy. I know it has been almost 2 years, would you mind guide me through the steps? I would appreciate it so much.
Thanks.

LG G2 Might be bricked, not sure.

Hello, cutting to the chase
Model: LG G2 D802
Story time: I tried to install ressurection remix rom through the sideload, after fully wiping my phone ( Wiped system, data, yada yada ) it showed some kind of an error about SU not installing properly, I thought well if I'll reboot TWRP will automaticly install SU for me, so when I tried to reboot it showed that No OS is installed, I thought it's a simple bug so I'll reboot to recovery again to check and bam. Nothing works.
+ Can't boot into recovery ( Tried volume down + power button ) LG Logo shows up and goes blank again ( Note that the screen doesn't turn off, just stays black, after holding it for a couple of seconds I can see screen going off completely but can't turn it on)
+ Can't turn it on normally.
+ Can't boot into download mode.
+After plugging it into an USB it mounts a D lettered drive with 63MB stuff in a folder called image with *.mdt files, modem files( I can screen it if it's important )
I'm clueless, never happened to me even though I flashed a lot of roms, I think I bricked it. Help?
UPDATE: I managed to quickly release Volume Down And Power buttons when LG appeared for half a second and hold it again, succesfully booted into TWRP. I haven't bricked it I think. Will tell how it goes <3
Hey man, how'd it go?
I'm in exactly the same situation as yours, can boot into twrp but nothing else works, i fear of the qhsusb_bulk brick but these people don't even seem to have recovery.
Any suggestions? Go back to stock? How?

How did it go!? I'm in a similar situation (but can boot into download-mode). Would love to get back to twrp, since I want to give it a try to flash another cm (stable). Thanks for sharing your experience...
If its picking up bulk mode normally its hard bricked there is a guide for restore nearly all g2s from hard brick having done it myself included 1st time took me a week to get back up but. Now i prob take about 45 min just cause i aint had one in a while

Hey there, can you specify what you did exactly or where to find!? Do you mean something like this? (can't post outside links, in XDA-forum, title is "LG G2 is UNBRICKABLE NOW! [FIX REAL HARD BRICK]") Thanks for help...
Yes thats it. Lol i still got the files on my pc for my g2 i keep the whe setup cause im on the g3 now i just check in the g2 forums cause i had mine for 2 years and modded the crap outa it but yea i keep all the files on hand so if anything ever happens i can fix it almost on the fly now
Well so what happened to me that I managed to get inside the TWRP. When it lighed it up for a second I quickly released and held again that got me inside magically. So then I just transfered new rom and tried to install again. Sadly I didin't see that the ROM Im trying to install requires bump TWRP and I bricked my phone again. Though I entered download mode and flashed the stock rom through LG G2 flasher.
heres a video i made, how to go into recovery. for those that cant get in to twrp.

HELP! Stuck in Boot Logo w/ no Recovery Mode

Ok so before I started writing this I had only one problem now I'm worried my problem has gone from bad to worse.
I updated my 6T to 10.3.2 from the latest Beta after the process it prompted for a restart, upon restarting it got stuck in the boot animation. I tried going into Recovery and Download mode unsuccessfully so I went through the forums a bit and saw that someone who had the same problem successfully entered Recovery mode by pressing VOLUME UP+DOWN+POWER buttons simultaneously, I tried to do the same and my phone turned off and now it doesn't turn on! :crying:
Has anyone experienced this or know how to fix this? Any help will be much appreciated. Tia!

These should be clarified:
Volume Up + Power while turning on will boot to fastboot.
Volume Down + Power while turn on will boot to recovery.
Holding Volume Up + Power should force the phone to turn off.
Volume Up + Volume Down should put your phone in Download mode for the MSM Tool.
Turn the phone off, let it sit. Then try turn it back on. Any response?
try to shutdown phone ...hold vol+ and power button for like 15 sec and restart your phone if this didnt work then u can try MSM tool
Thanks guys, got it working using MSM Tool!

You are likely going to lose your data. Know that going in if its not already backed up.
If you have the fastboot menu you can use the fastboot roms.
Or my least favorite option or what I would try last, MSM Tool (Tmobile 6Ts use a different tool).
IMPORTANT if you want to try and recover and data off your phone first, go to fastboot, and try and "boot" the TWRP img (not the installed one, one from your PC using the fastboot command). If that works you might be able to recover data. If that does worm, try dirty flashing the last ROM you were running and see if it boots.
No worries!

Hello, I am sorry to hear of you having this issue, I just went through 3 1/2 days (off and on) of recovering my T-Mobile OnePlus 6t which I found a way to get my unlock code within 2 weeks of having it, so I rooted it and put a custom kernel on it, stuck on 9.0 never let me update as I was not familiar with A/B partitioning, yet! The answers I saw to your questions were spot on, I just had a little to add to it and I'm sure I am not alone. Real quick let me list what has gone wrong on the rare occasion it hit the fan with the 6t...
- When I would accidentally and rarely let my battery die it seemed like it took forever to get it to reboot, I mean it sat on my desk of DOA devices for 2 weeks!
- It often seems like the buttons do not always respond properly and never have when I needed them to. Been through this before, I've bricked and unbricked and flashed and re-flashed and wiped all weekend and I like Android 10 and all but seems everything is different for every build, and everything seems to have to go in the right order with the exact right file or you wind up in a jam, period..
- That said, the previous person that answered your question has likely encountered similar, I've heard of right down to the buttons not physically working, but I have been a Smart Device Master III Technician for over 5 years, i know my buttons were not broken.
- Most likely culprit that I just handled and worked, i did have to use the MSM tool, several times - and re-unlock the BL, several times I would not even get the chance to get to fastboot, just a screen saying Build and Hardware not a match"" in yellow letters and it just bootlooped. No fastboot is no good, but when you said the tool would show some signs of working but then not, I have 2 solutions that I needed on diffrent occcasions.
1 - As mentioned fully try other USB cables, and ports, if you pull the usb-c out of the port and hold <power + vol up + vol down> eventually it will do something, very picky, sometimes gotta move your fingers to different spots on the buttons and also after 15-20sec let go of power and hit and hold it again... after a few seconds before it vibrates stick the cable in connected to your PC and the screen will be black (obv) but the msm tool will pick up on it. I know about the cables because I take good care of my phones and cables and charging ports, however on my final fix today it showed in msm tool it was connected but waiting for device.... Fed up i put the phone down and moved the usb cable a little bit and it picked up on it and did its thing! That part was just the cable, getting into qualcomm mode or w.e. is a bit tricky sometimes.
- Also someone said set it down for a while and come back to it.. THAT WORKS!! Let it fully charge and often just plugging in charger turns it on, bootloop soft brick or however have you, very simiilar to an Apple device and their DFU (don't f up mode cause screen is black..)
I hope that helps you get in touch with your family and friends.. Whatever you do, don't give up bc if you have not got it yet, you will! One other note, there are a few different msm tools available and they look the same some same size, but the one that supposed to work on my phone didn't and one that they say only a fool would attempt to try actually saved me, so if all else fails, use a different msm tool/usb cable and you will get it! I don't think I can post links yet I am on here very rarely, but plan on more! I have received so much help from XDA throughout the years on thousands of phones with just software issues alone, aas well as guides to my own phones. I would be honored to give back as I also have some extensive knowledge on many devices but I am a noob in comparison to many! Stay safe, good luck and please update and let us/ me know how it worked out for you. If i can help further I will, I have every firmware file for the OP6t, recovery, tools, software, this is not new to me but I feel your frustration!
