my son did something to his phone. it was unlocked and rooted. now it is locked and in a boot loop. only the first htc screen pops up and reboots from there. i can get into fastboot and bootloader but thats it. if i try recovery i get a pic of a phone and red triangle with exclamation point in it and it sits for a few min then reboots. in download mode i can adb and send fastboot commands, but the computer doesnt see the phone. i have tried the htc rom utility but it doesnt see the phone. also tried butting files on sd card and booting into download mode, it just keeps telling me the phone is locked. please help me out. if you need anymore info let me know and i will supply it. thank
joe
My first guess would be that there is a patched kernel installed (for root) and the bootloader is relocked. That would result in a bootloop like this because a locked bootloader can only boot the original stock kernel. So unlock the bootloader again and it should be fine. And if you want to lock the bootloader again, flash the stock kernel first.
im not able to unlock it. when i do fastboot flash unlocktoken Unlock_code.bin gives me an error and wont unlock. ive tried this command in download and ruu mode and neither worked.

Hmm, what kind of u11 life do you have? Sense or Andorid One Version?
Did you get a new unlocktoken from HTC or tried it with the first one again?
I think you have to flash it in download mode but not 100% sure.
its sense. this is what i get when trying to unlock
sending 'unlocktoken' (0 KB)...
OKAY [ 1.002s]
writing 'unlocktoken'...
(bootloader) flash unlocktoken
(bootloader) [KillSwitch] : /dev/block/bootdevice/by-name/frp
(bootloader) [KillSwitch] Last Byte is 0X00, disable unlock
(bootloader) [KillSwitch] oem unlock Turn Off!

Oh thats bad. To solve this you would need to boot into the system and go into developer settings to allow bootloader unlock. But as you are not able to boot into the system, i dont know what to do exactly. I have the android one version and this is very different. Maybe you could try to flash a ruu if there is a ruu somewhere. If someone with sense version could help you that would be much better.
So your facts are:
Sense Version
Bootloader relocked
something changed on kernel or system so system cant boot with locked bootloader
unlocking bootloader not possible because not allowed in developer settings
Yeah thats it. Thanks for braking it down for me.

I can't get the bootloader unlocked on a phone I just purchased with a relocked bootloader. I am on firmware 2.20 and my CID reads 11111111. I enter the unlock code and it says successful and I get the warning message on my phone about unlocking the bootloader and I hit yes to unlock. After the phone reboots all my data is wiped but when I reboot back into bootloader it still says relocked. I have tried multiple times with multiple unlock codes but no dice. I cannot get into stock recovery either after running the stock RUU. Anyone have any ideas? Thanks.

boot into the ROM and make sure USB debugging is enabled.. Reboot to fastboot and type "fastboot erase cache" and then try to unlock again

Bingo! That did the trick. Thank you very much. Man I do miss my old s-off phones.
I tell them what happened to me, my U11 phone had it with the European version and I did s-off with sunshine without problems, I changed cid BS_US001 and mid 2PZC50000 without any problem, but try to load the ruu that you download from htc 1.28.617.3 and came out error 155 that the image was not correct, then what I did was to close the bootloader with the command fastboot oem lock, reset the phone and send me to the bootloader screen, when entering download it appeared and s-on and Bootloader Relocked , try to load the ruu again but it tells me that the image does not correspond, try to install recovery stock, TWRP, and firmware 1.28.617.3 but it does not let me do anything, when trying to enter recovery it sends me to bootloader and if I try to unblock bootloader I gives frp error, it is clear that despite being relocked the bootloader I keep appearing the screen that has been modified the phone, when entering download I appears in OS 1.28.401.7 and putting fastboot getvar all if I see the c id and mid of the American version, but I do not do anything.
Do you think it has a solution?
Waiting answer ...
Thank you ...
Hi.
There are no answers yet, because, honestly, it is difficult to understand what happened. You wrote one single phrase that is 10 lines long. Try to reformulate, using listed items, paragraphs and so on.
Just a friendly suggestion, no offense.

Ok i may be way off base, but if the phone can boot into the OS go to developer enable usb debug and
Oem unlocking then follow the htc guide to unlock bootloader again ( not positive on that part never relocked a bootloader then unlocked) once that is done redownload the correct ruu per your cid and retry. Just my 2 cents. Hth.
you only flash full ruu 1.28.401.7

Hi,
I'm having a problem with my HTC U11 Life (US Sense version). After powering on the phone, the screen turns black after a few seconds. I have time to enter my code but accessing settings or other apps is impossible. The issue persists when I boot into safe mode, meaning it's an issue with a system app. Strangely, some system dialogue options stay on, such as the Safe Mode text and the power/restart/airplane mode display. I tried to unlock my bootloader using HTC's official method, but I don't have the setting enabled to do so, and I can't access the settings mode. At this point, I'm fine with losing all my current data if I can fix things.
For reference, this is what "fastboot oem get_identifier_token" returns:
Code:
...
(bootloader) [KillSwitch] : /dev/block/bootdevice/by-name/frp
(bootloader) [KillSwitch] Last Byte is 0X00, disable unlock
(bootloader) [KillSwitch] oem unlock Turn Off!
OKAY [ 0.043s]
finished. total time: 0.046s
TLDR: Does anyone know a non-official method to unlock the bootloader and flash the stock firmware?

I dont know if there is an up-to date system.img for the us sense version or if you are able to flash it with a locked bootloader but if you could get one, flash it and reset the device using the stock recovery it should work again. I dont think there are official full firmware/software files for the US Sense Version to flash with the stock recovery or a RUU but this would be the best way.
To unlock the bootloader you could also use sunshine s-off, if i remember correct it supports the us sense version of the u11 life but its about 25$ for each device you want to unlock.

I ended up doing a factory data reset via recovery mode, your guide really helped:
HTC U11 life [Collection Root Guide]
Thanks.
Hey there, first of all I just signed up at this forum but know and love it for a long time, so please bare with me if I make some formal mistakes.
But to the Problem.
I think I played a little bit too much with my old Honor 8 FRD L09 and wiped a little bit too much but basically now it's stuck in boot (where the blue Honor logo is) and doesn't boot further.
Can go into fastboot ( Phone Unlocked, FRP Lock)
Can't go into Twrp or maybe I just don't know how (I could go into TWRP yesterday but then I did something and now I can't)
Can go into Huawei eRecovery but everytime I try to recover I get the errorcode "getting package info failed"
I don't know what version of Android is on there but I didn't do systemupdate for a long time so I think it can be as low as Android 5.X.X if thats possible ^^
When I connect with ADB devices the list of devices is empty
When I do fastboot flash recovery it give me:
C:\Users\user\Downloads\platform-tools>fastboot flash recovery_ramdisk RECOVERY-V2.img
Sending 'recovery_ramdisk' (9100 KB) OKAY [ 0.223s]
Writing 'recovery_ramdisk' FAILED (remote: 'Command not allowed')
fastboot: error: Command failed
So yeah, I honestly don't know further and all the other Threads here to recover my phone didn't work (most of them say go into fastboot but the I always get the same error on every recovery image I try)
So is there a greater fate to my tried and true Honor 8 than beeing remembered as a bottleopener?
Pls fast help, thx guys
You have relocked your bootloader, because of that you can't install flash recovery. Now you should unlock bootloader in fastboot with this command: fastboot oem unlock <unlockcode>. Unlock code is the code which you use for unlocking the bootloader.

Bootloader should be unlocked cus every time I go into fastboot mode on my phone it says bootloader unlocked, but I'll devinitaly give it a try later when I am at my computer
When I tipe the code in I get this:
C:\Users\sarah\Downloads\platform-tools>adb devices
* daemon not running; starting now at tcp:5037
* daemon started successfully
List of devices attached
C:\Users\sarah\Downloads\platform-tools>fastboot oem unlock
< waiting for any device >
FAILED (remote: 'Command not allowed')
fastboot: error: Command failed
I don't have the Unlock Code anymore. I tried to get it from the Huawai homepage but there I can register with my Huawai ID but I can't find the unlock code and I also don't know if it's even saved in my account on the homepage.
I also tried third party apps to unlock the bootloader, but with all the apps I used the phone has to be turned on and that is not possible
Check out my post for a fix

I was trying to downgrade to android 6 (FRD09), phone stucked at bootloop. Cant do anything. i just waited to let the battery died, and now i cant charge the phone. When i plug it to charger the screen is blinking with thunder image, so doesnt charge. When ı connect it to pc just on fastboot mode connecting. How can i restore this phone?
Hey guys,
I am trying to unlock my bootloader but it doesnt work, everytime I do the "Fastboot oem get_unlock_data" command, it says it failed to get unlock data.
I have unlock bootloader option in dev settings enabled and all drivers properly installed along with fully working sdk and fastboot tools etc. I have a couple xiaomi devices with different custom roms.
Previously I installed RETLA using tiny fastboot script cus i bought the phone in latin america but software channel says RETAR... Is this discrepancy the problem?
If not, anyone know why even though bootloader unlock option is on, the fastboot command to get the data fails?
Using getvar all i see the cid is 0x0000, i've read that having cid: 0x0000 is the problem, might installing the proper firmware: RETAR change this?

Most likely you will have to forget about unlocking the bootloader.
Reflashing will not help you in any way.

Do you know why the cid is like that? Idk what has been done to it cus I bought it used. Any ideas?

The boot loader on your phone was blocked incorrectly and the system stopped starting.
cid: 0x0000 is a consequence of the boot loader working state recovery software.
It is now in a state oem-locked" as it was originally from the factory. But you cannot unlock the bootloader now. But, if I'm not mistaken, you can install firmware for any update region without having to unlock the bootloader.
