[Q] Bricked device: fastboot and other problems - ONE Q&A, Help & Troubleshooting

I've bricked my Opo. The story:
I rooted the phone in July. The bootloader was unlocked, TWRP 2.7.1.0 installed. I made two updates (last was CM11S 33R) then I encrypted the phone.
Yesterday I wanted to update to 38R but wasn't able to mount data part in TWRP. Because nothing happened when I tried to make a factory reset I decided to format the data part. That was my fault because then TWRP told me then that there was no OS any more!
Ok, then I started fastboot and tried to flash the new version of CM11S onto the device, but fastboot told me that the phone wasn't unlocked so it can't copy the file.
Fastboot recognised the device, so I tried to unlock. The input "fastboot oem unlock" gave back an OKAY, but "fastboot oem device-info" told me:
<bootloader> Device tampered: true
<bootloader> Device unlocked: false
<bootloader> Charger screen enabled: false
I can try to unlock the phone again and again but it changes nothing.
The device has no OS. I can boot fastboot and TWRP but nothing else.
I hope so hard somebody can help me!

have you tried anything from this thread.

Sounds like your EFS got corrupted to me. The fact that your device boots into Fastboot says that you still have hope and its not really bricked. Bricked would be at the point that the device doesn't even turn on or boot into anything.

I was able to copy the ROM with adb sideload, so my phone isn't a brick any more!
But I can't unlock the damned bootloader. Now I will read the thread You linked.
Trouble let me learning more and more...
Thank You!

[Q] "Fastboot oem unlock" Does nothing.

I have owned this phone for about 5-6 months now and have never unlocked the bootloader. I know I probably should of done that when I got it but for some reason I have been able to flash TWRP, Root the phone, and install custom roms without wiping the phone no problem. I am currently on Paranoid Android 4.6 Beta 6 and TWRP 2.8 but I wanted to go back to CM11S, and I thought maybe it's time that I unlock the bootloader. I have installed the correct drivers and when I type "fastboot oem unlock", the Command Prompt said "finished in 0.06 seconds", I then rebooted and nothing happens. I also tried a Toolkit to unlock it but that didn't do anything either. Can anyone help? I don't want to Hard Brick my phone.
Thanks
It sounds like your bootloader is already unlocked.
Try running
fastboot oem device-info
to see what it says. Post your results here and somebody should be able to help you.
The right command is:
Code:
fastboot oem device-info

Thanks, edited to fix.

I dun goofed, messed up my OPO.

Okay so, first things first:
I can boot into both Recovery AND Fastboot
ADB Sideload does NOT work in my TWRP
Tampering bit is true and bootloader unlocked is false
My problem now is;
I need to unlock my bootloader because right now, my phone has no OS. I can't unlock it though because neither fastboot oem unlock works nor through the OPO Toolbox/Toolkit.
I can't flash anything to it right now and I need to find a way to unlock my bootloader, whenever I try to unlock it, it reboots to TWRP.
Please help. <3
adb push yourrom.zip /sdcard
Then just pick the ROM you just copied onto your phone storage using the above command in TWRP and you should be fine.
If that doesn't do the job then you can always use the brick recovery download tool.

Did you try flashing the OPO factory image and then start from scratch?

Softbrick cant access rebootRUU screen

Hi, I did a few searches but came up empty, sorry if this is something answered already.
A friend brought me a sim unlocked Htc One X from at&t stuck in a bootloop and I can't get it out of the bootloop, he supposedly tried to update the device with an ota delivered to his device and it just entered the bootloop, the device is completely stock so I cant unlock the bootloader to flash a custom recovery, I can enter hboot and fastboot but trying fastboot oem rebootRUU causes the device to reboot and go into bootloop so i cant use an RUU to flash everything back, same thing with trying to enter the recovery, trying to factory reset the device or any other option in fastboot or hboot that isnt turning the device off or changing between hboot and fastboot.
Is he SoL? I am not that familiar with htc devices but from what i've reasearched I think there is nothing to be done for it right? (I hope I am wrong)
Try flashing boot.img in fastboot.

your device is corrupted and cannot be trusted.

Hello,

Sounds like the bootloader was modified, which breaks the digital signature.
Try unlocking the bootloader again and reboot. Go into developers options and turn usb debugging on. Then connect a cable between your computer and the phone. An RSA signature key should be presented. Check the box "always accept from this computer". Then try rebooting into fastboot and flashing stock.
Not sure of this will help but that's the best advice I can offer.
Cheers,
B.D.

[SOLVED] Lenovo VIBE K5 A6020a41 Bootloader refuses to unlock

EDIT:
fastboot boot and fastboot flash WORK even though
fastboot oem device-info shows thebootloader is NOT UNLOCKED.
If that still doesn't work try to flash some other compatible stock rom for your model with qfil and try the fastboot boot and fastboot flash commands again, don't care about unlock status, it worked for me successfully flashed twrp and a custom rom.
Hello!
My Lenovo VIBE K5 A6020a41 refuses to unlock its bootloader.
Output of fastboot oem unlock:
FAILED (remote: 'oem unlock is not allowed')
I have enabled developer settings, usb debugging and Unlock OEM setting.
I found some posts of people with the same issue and smartphone model and they said they fixed it by flashing another stock rom (they didn't specify which).
I have flashed two or three other stock ROMs with QFIL, one was for A6020a40 model and the other two were for my A6020a41 model.
Again, I enabled all the necessary settings and still couldn't unlock my bootloader, showed the same error.
Then I tried flashing TWRP through QFIL, but when I rebooted into it, Lenovo logo showed for a second and then a black screen forever, I also tried to see if adb was able to detect it as a device in recovery, but it didn't.
Then I managed to root it with KingoRoot(I know it is not secure and it is bad and all, but I just want to flash a custom rom anyway), so I installed the official TWRP app and an app called Flashify, both flashed TWRP successfully, but I couldn't boot into the TWRP again, Lenovo logo for a second and a black screen.
Do You have any suggestions please?
Thank You.
Try
Code:
fastboot flashing unlock
what is the appropriate command on newer devices.

Already did. This device supports the older one only. (Should support)
Hint: Add " Lenovo VIBE K5 A6020a41 " to front of this thread's title.
