Hello,
first... sorry for my bad English.
Since yesterday my Acer A510 doesnt boot. (I have done Nothing. I used the Stock ROM)
Cannot boot into the Bootloader. The Device only enter into Fastboot.
I want to try flash CWM-Recovery, but i cant unlock the Bootloader.
"
C:\fastboot> fastboot oem unlock
...
FAILED <remote: <Unknown error code >>
finished. total time: 2.166 sec
"
Cant install any Image or update.zip, because the device says "Bootloader is locked"
Can anyone help me?
so my phone froze today so I took out battery and turned it on and all it does is go to the boot loader.
So I decide to try recovery all this does is flash android logos and then back to same screen,
Next I try factory reset and same flashes to android logos and back to same screen
After reading this forum
I then go through the process of unlocking my boot loader via htc dev the process goes great I receive email etc etc
The final process should bring up a disclaimer on my screen but nothing
So my question is wtf what do I do?
Please help me
Check the guide at HTC side if you have done everything correctly, all is written how it should or copy and paste.
Without unlocked bootloader, there is no chance to rescue your phone.
Any information about your phone model and exactly the step it fails is important, too.
this problem has such a friend, and it does not solve constantly locked bootloader ...
Does anyone solved this problem?The same situation of my phone?Please help!
Hi,
i flash 2.8.4.0twrp, then make backup, after that (whit in recovery options) try to make factory reset, and after that my one sv is messed up like hell...
It is not booting...stuck for a while at htc logo, screen goes black, then loads bootloader, I am able to go to twrp (I have fresh backup of complete phone, did it with twrp above), but not able to flash anything...it fails every time, saying that is unable to mount cache...try advance wipe, but it is not able to mount any thing...
Since my phone was S-off, unlocked bootloader, superCID (it is k2ul), hboot2.0, I tryed with fastboot oem relock (to lock bootloader, and flash stock pl80img.zip) but that fails too, ends up with to many links message...and bootloader stays with tampered and unlocked sign...before flashing 2.8.4.0twrp phone was working great, but after factory reset it is not able to mount anything, and running pl80img.zip gives me all so only fail...fail...fail...
So..now i have latest twrp and totaly messed up phone...
How can U help me, anny advice???
THX in advance!

You need ti unlock your phone,otherwise you can't do anything.
Hello Guys, I am new to the forum. I read a lot of threads, but no one i found had the solution or the exact same problem i have.
I bought a new Xiaomi Redmi 4X and wanted to install the los 14.1 Version I found here in XDA (https://forum.xda-developers.com/android/development/rom-2017-08-07lineage-14-1-t3653016). (I have installed custom roms a few times before and also faced some problems)
I flashed twrp via the fastboot mode using my linux laptop. I installed the los zip file and booted into it, but it was stuck in a boot loop. I wanted to go back into twrp, but it did not work, so i tried it with the fastboot again. Then I saw that oem is locked.
As root user i tried to unlock it with
Code:
# fastboot oem unlock
...
FAILED (remote: Token verification failed, reboot the device)
finished. total time: 0.004s
but it doesnt work.
So I am stuck now without any ROM and Recovery, I can only access to the bootloader.
I am happy for any help.
update 1 : error mode gone and when the phone starts honor logo then eRecovery
bln-l21c432b371
I was on twrp rooted unlocked bootloader so i decided to go back to stock
tried dload method not wroking 5 % failure with b371-372-374
tried with fastboot FAILED (remote: Command not allowed)
tried flashing using twrp succeeded but the phone booted into error mode but I was able to enter fastboot and eRecovery as twrp was gone
so I tried eRecovery to load stock connected to wifi but says after getting package failed
so I tried to relock bootloader to re unlock it to use fastboot without the error and I succeeded to relock it but failed to unlock it again as fastboot FAILED (remote: Command not allowed) and I was stuck in error mode with bootloader locked frp locked
waited until the battery died and I can now access fastboot and eRecovery and dload mode
tried the the 3 ways and still the same errors
and I can't get into anything
any help?????????????
