Hey!
So i'm making this post after battling over 4 days with my friends old oneplus 3t.
All started maybe year ago when my friend asked me for help because his oneplus had suddenly gone into a bootloop kind of state (he told me that the phone was in his pocket working fine and when he tried to use it next time it started acting up.) Before i could even help him he had already bought new iphone, so the oneplus stayed in his drawer until last week when i remembered it and started to try to fix it.
So first thing that i noticed was this message "The dm-verity is not started in enforcing mode and may not work properly", the message eventually went away and i got to a recovery mode and thought that this is gonna be easy, hooked the phone to pc and started adb and tried to sideload the official rom from oneplus site, but everytime i tried it went to maybe 47 %or 66% and failed eventually. So i thought that ill try flashing original recovery.img, started fastboot and tried flashing and everytime "remote: Partition flashing is not allowed". Tried many times also oem unlock command and failed miserably, all i got was "remote: oem unlock is not allowed". Eventually trying every command from fastboot and adb i came to a conclusion that the device doesn't allow anything to be written to its storage (Tried of course flashing twrp, but same error).
Downloaded Oneplus 3T unbrick tool v3.0, and qualcomm drivers (turned windows driver signature off) everything went great and the green text came in oneplus unbrick tool and i proceeded to start the phone in excitement and the circling bootlogo started and it just stayed there, nothing, and after while shut down.
Things tried now:
-Sideloading (many times with different roms) no success.
-Fastboot (It recognizes the device everytime, but all other commands than "fastboot devices" end to an error"remote: something not allowed") no success
- Unbricktool v3.0 (Works like a charm everytime, but phone doesent still boot to os) no success
-recovery (wiped cache and all data many times) no success
My friend never flashed anything to this device, he doesn't even now how to do this kind of stuff.
Phone not dropped even once, is in a perfect condition and has all the original stickers even.
I have grown obsessed to fixing this phone, so any help is greatly appreciated :laugh:

I haven't personally ever had to use the unbrick tool, so I can't help too much with the core problem. But what I can say, is that the steps I've quoted above (trying to flash recovery partition, etc.) are going to fail by design, since the bootloader is locked. This is the very purpose of the locked bootloader. The expected result is "remote: not allowed".
And as far as I am aware, you have to have a working OS and have "OEM unlocking" first toggled on, in the phone Developer settings. Otherwise (again, by design) the "fastboot oem unlock" command is going to fail.
Spontaneous failure of the phone to boot to OS, and dm-verity warning, to me probably indicates the OS has become corrupt/damaged. The damage is showing as a change to the system, therefore the dm-verity warning. Normally, I would tell you to flash the stock recovery image. But of course you have already tried that. Probably difficult to determine for sure. but spontaneous failure, and failure to flash recovery image (multiple times) may indicate a hardware failure such as bad emmc.

Hi guys,
I am trying to help out a mate and unfortunately dont have much experience with HTC's.
This is where i stand...phone wont be recognized in normal boot, nor in TWRP, so adb is not working at all. FASTBOOT works.
i have been circling around with locking and unlocking the bootloader to try out all the methods of updating the system, RUU fails with error 155. when unlocking, supercid fails with some java error.
To get S-OFF, i definitely need adb to load the "much talked for" file, but that is impossible right now.
RUU normal way fails as i said above, so does FUU with rom.zip (found away to get it out of exe, so it is untouched) as soon as it "updates signatures" it'll fail, I even use the fastboot command with the renamed file firmware.zip ends up saying it cannot verify partition ...adding zip after flash command says file is out of size
I am on 4.20.651.10, and trying to get the latest package, and am out of ideas. I found out the hard way that if i lock back the phone, it wont boot to TWRP and nor on a modified system.
I am really not sure what to do, having adb on would've spared me a lot of trouble. Friend says the USB port has been changed twice, it is so odd to have fastboot and not even a single refresh in Device Manager when i plug the damn phone on...
There are more replies to question threads outside the Help section then in here...
Anyway, i lost fastboot too, and no idea why. tried in two pc's, one of them with 3 different os's, tried two macs, tried even an OTG cable with my other android phone, nothing.
I cant even relock the phone so i can update through the RUU ZIP in the sdcard, but that's a scratched off solution if no USB connection is delivered.
I even tried the S-Off unlocking file on /data/local/tmp, but it doesnt seem to execute from TWRP terminal, and ofc it wont through a booted system either...
I managed to install a custom rom since i have no OS, and tried the "AndroidHtcSync.apk" solution to no avail
i seriously hope anyone has the will to help me...
EDIT: port is definitely fine, as the phone charges from the charger, and fastboot shows "fastboot ac".
EDIT2: fastboot is back... renamed the zip in sdcard, now it fails flashing there too with "Device halted due to large image update fail"
Hello XDA,
Ok, so I'm going to try to explain the best I can. My roommate has a Nexus 6 (Project Fi if that matters). She went to install an update, although I'm not sure which one. She said she thinks it was "7 something". I'm assuming it was 7.1.1 since that is the one that I was last notified about on my phone and she said the notification appeared only a few days ago. After she installed it the phone was stuck in a bootloop (the spinning colored balls screen).
I Googled solutions and tried wiping system cache from recovery mode. That didn't work, so I asked if she had anything important on the phone and if I could do a factory reset. She said I could go ahead and do it, however that did not work either. So then I plugged the phone into my computer and fired up a terminal session to flash a factory image to the phone. I entered "fastboot oem unlock" so I could proceed . It came back with the "see developer options" message. Ok, cool, but I can't get into the settings app to enable OEM unlocking.
So since I did the factory reset and can't boot into the OS, is there any way to enable OEM unlocking from the bootloader? I'll keep looking for answers in the mean time.
Thanks in advanced.
EDIT:
Found a thread with the OP having similar issues. I tried "fastboot format cache" and "fastboot format userdata" which both failed with "Not allowed in locked state!". Even though I got the errors I tried (out of desperation) to boot to TWRP with "fastboot boot ~/Downloads/twrp-3.1.0-0-shamu.img" which failed with "FAILED (remote failure)".
EDIT2:
Tried downloading 7.1.1 OTA image and sideloading via "adb sideload shamu-ota.zip" from the bootloader recovery mode. Failed with "error: no devices/emulators found".
Sideload an OTA image. That should resolve the bootloop so you can enter Android to unlock the bootloader.

Thanks for the reply. I tried it and it failed with "no device found". The command "adb devices" gives me an empty list. Not even ????????.
If ADB isn't seeing the device you potentially have a hardware issue.
i got same problem.
no oem unlock cuz is in bootloop
locked
erasing
@luisq93: Yours is a different issue. The solution for you is to do...nothing.
The erase part of the factory reset MUST complete, or you may end up with unusable internal storage until an uninterrupted factory reset is completed. So all you can do is be patient.

like 2 month and half patient?
cuz the erasing changed language 2 months ago and nothing more... from italian to English, maybe i should just wait... thanks for the advice.
@luisq93: How long did you leave the N6 running the very first time the device started erasing? I'm willing to bet you only gave it a few minutes, became impatient, shut the device down to restart it and upon restarting encountered the erase mode again. Consequently you thought it bootlooped and put it in your drawer.
Until you let erase mode complete, every time the device boots it will immediately enter erase mode, because the erase must complete to avoid corrupting the internal storage. Erase mode, especially on an encrypted phone, may take a while. I had one instance on another of my devices take an hour.
So the solution to the erasing "bootloop" is to do nothing except plug the N6 into its charger and leave it alone.
I have tried multiple times to install mr3 global image, I have all drivers installed and device showing however always get an error . However I managed to get it going but Fastboot stoped on system.img when using flash_all and I think that's what has caused my phone app to crash the whole phone when I try to ring someone... If any one can help it would much appreciated... Thank you
Sorted this by flashing to MR2 factory IMG and I run in to critical partition error but the .IMG files all seemed to carry on installing on the phone It ended up my phone not booting and saying device is corrupt and cannot be trusted thought phone was bricked, how ever I fixed it ...
even though it was already OEM unlocked I just fastboot OEM unlocked again and flashed MR2 and it booted .. updated OTA to MR3
Hi, after flashing newest Legion OS I have a small problem. Every time I restart my phone, it enters fastboot, all I have to do is to connect my phone to PC and use "fastboot continue" then phone normally boots to system, until next restart. It's not a big deal, but sometimes I forgot about this problem and restart my phone when I don't have pc near by. I tried "fastboot oem fb_mode_clear" but all I'm getting is "FAILED (remote: unknown command)"

That's a new one on me. Normally, if the phone boots into fastboot instead of system, it's because there's a problem with the ROM installation (typically it's an encryption problem with this phone). In which case you wouldn't be able to boot into system at all (if the problem is encryption then formatting data would fix it). Not come across a case, so far, where you could successfully boot into the ROM from fastboot in this scenario. Maybe it's a LegionOS issue - possibly the dev was debugging and had the ROM go into fastboot first, then forgot to remove this before releasing it.
The fastboot oem .... command allows oems to introduce their own specific commands for their phones.
As far as I'm aware fb_mode_set and fb_mode_clear are Motorola inventions, and so will only work on some Motorola phones.
I would suggest either asking in the LegionOS thread, or backup everything and try clean installing LegionOS again.
I have exactly the same problem as you after flashing newest PE （Clean flash)
Solved: flash miui 12.0.x.x based on android 10 before flashing custom rom.
I've been an android developers for years and years now and even have made my own ROMs, but this phone....this phone is testing me. I unlocked it months ago to install an original Android 11 ROM, but it was awful and lacked support for even the most basic functionality, so I flashed the stock image back. That alone was a nightmare and I don't remember how I managed it. That being said, the Asus Android 11 update is rolling out OTA and can be downloaded directly from their site. I downloaded it and put it in the root directory, where it is found on start-up, but when I tell it to install, it fails after a few seconds and doesn't give me any explanation for it. I thought it may be that the bootloader is unlocked, so I've been trying to re-lock it for weeks with no success. I managed to get the damn fastbootd mode recognised by my computer and it sees the phone, but when I give it any relock command I receive this error:
"FAILED (remote: Command not supported in default implementation)"I have no clue what to make of that or what it even means. My only guess is that the commands I'm using aren't supported in the latest version of the tools. I've tried the following commands:
fastrboot oem asus-lock
fastboot oem lock
fastboot oem asus_csk_lk
fastboot flashing lock
fastboot oem relock (I don't think that's a real command, but I was irritated and figured it was worth a shot)
I'm at a total loss. All I want is to get Android 11 to the damn thing and the OTA isn't coming through to my phone. The phone itself is an international model I bought from China back before it was released in the US. IDK if that's causing a problem, but at this point I'm out of ideas. I'd also note that normal fastboot, found by going to the bootloader instead of "adb reboot fastboot" doesn't even allow the computer to recognise the phone and when I try to install the fastboot driver via device manager, it outright refuses to install it. There's no apparent way to get it to install the driver anyway. I AM able to get it to install the driver and see the phone while in fastbootd mode.
Anyone got any ideas?
fastrboot oem asus-lock
This worked for me on tencent phone converted to ww firmware. I had no troubles with updating to 11 from 10 as well. I had also no troubles to flash raw firmware with bootloader unlocked.
Waiting now for new ww firmware as CN has been already released couple days ago.. If they didn't fix thing I'm annoyed with I going back to 10!
Try different cable. Had guy from reddit with same problem like yours and simple new cable sorted everything
fastboot oem asus_csk_lk should do it.
I think you may be in the wrong fastboot mode You need to be in the bootloader. Try powering off and boot with Vol UP + Power until you land on the bootloader page (don't navigate to Fastboot from the bootloader menu, just stay on the bootloader menu. Doing 'fastboot reboot bootloader' should also do the trick but suggest trying with the physical buttons.
