================================
Hello,
This afternoon, I was preparing to flash Oxygen OS 2.1 through twrp but I wanted to make a backup first. Attempting to load up twrp by holding Vol- and Power, my OPT flashed the starting frame of the boot animation for half a second before turning off. This repeated every 5 seconds. I could still boot OOS normally at this stage.
I decided to reflash twrp so as to make the backups, but on attempting to flash it, I saw that my bootloader was locked. So into fastboot mode I went, but trying to unlock it, it did the same as trying to get into recovery. As soon as I sent the command, "fastboot oem unlock", the screen went dark, flashed the starting frame for the boot animation, and promptly when dark again.
I now can't boot up normally, nor can I enter recovery. I can access fastboot mode, but I can't seem to make any changes.
I've attempted to use this solution as well as several other similar ones with no success.
I've had my OPT since 17th of August with absolutely no signs of trouble until this afternoon.
To me, it seems like it could be a hardware issue, but I'd hope it would last more than 40 days.
Any suggestions?
Thanks.

What were you doing before it occurred? Perhaps we can work out the cause.

I'm not sure what I was doing, I was going to flash different ak kernel as my wifi didn't work.
HOWEVER
I read someone suggesting if you still have bootloop after trying the qualcomm recovery tool, try booting to fastboot and use: fastboot continue
my opt booted nicely to hydrogen os and after I shut it down it no longer bootlooped and I was able to get to recovery.
I'll post this to your reddit thread too, maybe it might help somebody one day, hopefully this works for you too

Mate! that worked for me too!
However... It only seems to skip the bootloop for that power on. After power off, it returns to the boot loop. I also still can't unlock the bootloader and can't access recovery.
But at least it can boot into OS with fastboot continue!
Thank you.
Weird, after the first successful boot I rebooted and a chinese menu prompted me if I wanted to unlock the bootloader, and I did.
Maybe you should try different recovery packages.
But I'm glad to hear you at least got past the boot loop

Can't flash a new one since the bootloader won't unlock :/
I guess the phone is in working order at the moment, I just can't let it get turned off without my computer next to me...

Nono I mean different qualcomm recovery packages, the ones with MSM8994DownloadTool, I also replaced the stock recovery in the qualcomm package with twrp just in case if that matters

Ahh, do you mind linking me to the one you used?
I think I used this: https://mega.nz/#!EsNQHKab!ifATzg4rxxBniPad0iyxANqlN8cZpUx2MVWaZgEhrD4
but it might have also been this: https://drive.google.com/file/d/0B14IjYN3PtxcSlJ5aGQxX3JERHM/view?usp=sharing
It's also worth mentioning I flashed both a few times before I tried the fastboot continue command so try both a few times and see if that helps, also I replaced the stock recovery with twrp in both recovery packages before flashing.
Edit: And best of luck, I'm rather confident your OPT is going to work properly again.
Boot Loop
I got the same problem.
Phone is rooted and i can't unlock it in cmd, just reboot itself when i try it.
The only way for me to even start the OPT is to (volume+ and power), to get to fastboot mode, then run "fastboot continue" twice in cmd.
If i reboot the phone it get cought in a boot loop where i can see the logo, reboots about every 2 sec.
Is there a solution for this? I've been searching 2 for two days now.
I don't care if i have to reset the entire phone.

I got TWRP installed but its unreachable, volume- and power ends in boot loop.
I can´t install anything when the phone is locked.
I even tried a Factory reset, boot loop and no change when i got it up again.

I finally got my OPT working again, tried Qualcomm recovery tool, wasn't able to complete the "MSM8994DownloadTool"
So i downloaded "A2001_14_A.03_150805" in a guide from technobuzz.net/unbrick-oneplus-2/
A similar but it does a entire wipe of the phone, nothing left at all. WARNING!
But i was okey with it.
Well the phone was in Chinese when it was all done but to change language was no problem.
I finally managed to solve it on mine. I had been cautious over the past weeks to not let it run out of battery or get turned off while away from my computer as
Code:
fastboot continue
was the only way I could get past the boot loop.
My core issue to solve was that I couldn't get it recognised as the USB Diagnostic 9006 under Ports in Device Manager. I installed the driver from here manually by right clicking the /qcser/x64/qcser.inf file and selecting install from the context menu. Then, I powered off my OP2. While only holding Vol+ (not power or Vol-), I plugged in my OP2 to the computer and it was finally recognised as the 9006. Then using the recovery tool from the prior link, it installed and rebooted my OP2. The moment of truth was when it rebooted and didn't enter a boot loop!
Then with the Chinese recovery prompt, I selected the top/first option and it brought me to the welcome/first setup screen of OOS.
It wiped the internal memory, and installed OSS 2.0.2 (don't know if coincidence or not as that was my prior OS as well). Now to install twrp and update to the latest OOS hopefully without a hitch.
Happy to finally know it wasn't a hardware issue like a failed eeprom or a dud nand controller as my prior phone (Samsung Note 10.1) died to a failed nand controller as well.
Will update with news of twrp and OOS, but I feel that should go smoothly now. Thanks to the others that helped in this thread too!
Yeap, all good!
Flashed official twrp through fastboot and batch installed OOS2 through 2.1.1 patches and SuperSU. Everything working like new!
Phew.
hi can one of you guys help me out? on teamviewer? mine is stock in the bootloop and i can only get it to boot up via fastboot continue. and i cant figure out how to get it to work. i would like to go back to complete stock and no root

BLN-L24N - Honor 6x
Sooo, I have the same problem , here's my story. Please help I've resorted to using a SGH-T599N... Its embarrassing... I'd almost rather have an iPhone...
So Little ol' me was messing around/ deleted google play services/ reboot to twrp to recover but device ended up bricked. At the time, still able to access fastboot. I flashed recovery and firmware. I then tried dload roll back method and when it cleared the phone bootloader locked. So I unlocked bootloader again but when device re-booted the following screen came up and still remains:
" ' Your device has been unlocked and cant be trusted. ' -- ' Your device is booting now... ' " (No options are available.)
I eventually tried to restart to fastboot or erecovery BUT Everytime I try to power down the device, it tries to power up again but needs to charge for a minute before trying to boot itself back up. .(even after being on the charger for hours this happens). The problem with that is I can't get into fastboot or force dload because it automatically starts itself/ has to be plugged in until it turns back on. (Yes i've tried button mashing/ button holding/ etc. did not help)
How do I get the phone to charge, without it booting up? I have a feeling that if I can get it to start (without it first having to charge) I can get it to fastboot/ or erecovery. I have already tried to let the battery COMPLETELY drain.
Outside of that, I know the whole roll back and dload stuff. Currently it flashes the honor logo screen and then sits at "Your device is booting now..."
Bootloader is unlocked
OH! I should clarify, it boots on its own. I've tried disconnecting the battery, having it on the charger without the
battery. With the battery, Starting phone up by re-connecting the battery. No positive results
I'm about to start messing around with firmware flashing utilities, I just don't know of any. I wish there was a way to flash without being in fastboot mode. (I know very little of perl/python/linux, but I am a quick learner if you point me in the right direction.
Thank you in advance

So on ny phobe the mainboard is dead so i guess the internal storage is corrupted
I need to change that and i guess you need too...
It's not so expensive(like 40$ for my phone)

I just tried to flash a new rom onto my XZP, and upon rebooting from TWRP, it didn't load the rom. Just boot looped. I restarted and tried to get back into TWRP with pow+vol down, but it still boot loops doing that and it doesn't vibrate on the boot like it did before. It still just gives me the "device is unlocked and cannot be trusted" but that's it. No Sony logo, or TWRP. I tried using the "adb devices" command but nothing shows up. I cannot find out why. In device manager on Windows 10, it shows up as "Android" under unknown devices, but I can't find a driver that actually works. Anyone know what to do?
Which rom did you want to flash? Looks like you did something really wrong dude. The best you can do is just flash a stock rom with "Newflasher". You can get the with "XperiFirm". The correct device drivers are ready to download on the Sony developer website. Here are some informations about drivers for XZP and other devices.
Maybe you can get the drivers working, then flash TWRP again and do what you planned to do. But I really recommend to flash a stock firmware instead.
Did you also try to power down the handset with the Vol+ and Power buttons? If you hold them for 3 seconds it just restarts the phone, but holding the Vol+ and Power for 6 seconds turns the phone off completely.
In my attempts to flash LineageOS to my OnePlus 6T, I have 1) unlocked OEM in the developer settings, 2) booted into fastboot, 3) ran fastboot oem unlock, confirmed a disclaimer that data on the phone would be wiped, and let the phone do its thing. It booted regularly and showed me a first-time setup screen. I then shut it down to boot into fastboot again. But, it has decided that it won't cooperate.
I really have nothing else to go on, maybe just that fastboot oem unlock finished in 0.038s, before I confirmed anything on the phone. The host is a Ubuntu 21.04 machine and the phone is running a manually installed update to Android 11.
My oh my what have I gotten myself into. Please help.
EDIT: This is not a boot loop, all I get is a black screen. The phone used to vibrate when plugged into power, it doesn't even do that anymore.
Plug it into computer. On computer right click windows logo and select device manager. In the window search for every device. If I have guessed it, one of them shows Qualcomm 9008 or qusb-bulk. If that is the case tell me.

My guess is what you get is Android's BSOD ( read: Black Screen Of Death ).

Give your device to service centre maybe they'll do something about it
Hey all, I recently flashed a new rom on my phone, which required me to factory reset my ticwatch I'm order to reconnect.
Upon doing to the first time, everything seems to have gone well, but had trouble connecting to the device. So I ran another factory reset. Since that one, I've been stuck in a boot loop.
I see the "device software can't be checked for corruption" screen for about 20 seconds, and then it vibrates, screen turns off, then I see the same screen again. And so on.
I tried letting the battery go to nothing and trying again, seems to be the same issue. I'm letting it charge and bootloop for now in case maybe I just don't have enough juice to make it through boot.
It is rooted, with custom ROM (followed a guide on this forum somewhere about half a year ago, was running great) and TWRP installed (at least it was, I've been unable to get to the recovery screen since the boot loop started). Cannot see it in adb ever in this process.
Anyone have any other suggestions? I remember the Samsung notes had a special USB tool that would bridge a couple pins to immediately go to recovery, is there a similar option here?
Can you get in usb mode,or fastboot or recovery maybe?There is solution..dont worry.I ghuess adb dont work,but you cant go to fastboot mode and boot twrp image and get in twrp recovery..in twrp recovery you need backup file..If you cant do that,we are going to another solution..
Yeah, I can't - via any combination of button holding - get into any booted mode. No recovery, no fastboot, nothing. If anything, some buttons seem to make it circle boot faster .

,Yeah tough situation,and when you connect it to pc in that "broken mode" -boot loop and open adb shell on pc ,comand adb devices or fastboot devices,does it show device?When you screwed boot and you have twrp there must be option to get in twrp.One trick more go to manage devices in pc find your device if unknown you right klick on it,update drivers,manually,and then choose android,then android adb install device.

No go on either command. Nothing shows up.
I'm half wondering if it's my battery at this point. I think I'm getting a new watch for Christmas anyway, so not a huge loss. But happy to keep trying if anyone else has any ideas.
