You can't flash TWRP until you unlock the bootloader.

Unlocking the bootloader via fastboot and HTCdev.com has *nothing* to do with USB debugging being on or off.

Follow the instructions at HTCdev.com to unlock your bootloader.

Forget adb, forget toolkits, just focus on HTCdev.com - it's not difficult.

Unlock the bootloader.

Install TWRP.

Make a backup in TWRP before you change or flash anything else. (All of the know it all blogs and toolkits skip this step and it screws you if you don't do it.)

Then set about rooting or whatever else you're trying to do.

I've followed all the instructions on the htcdev website till i got the black screen with yes or no to unlock the bootloader on the phone . This

Then when i highlight yes and select it by pressing the power button the phone vibrate and it bring me back to the htc logo .seem it doesn't reboot at all.


What to do now??

Thanks
 
I'm concerned about the bootloader commit number.

Was this phone bought used recently?

Was it working correctly before you started all this?
 
Follow the instructions *exactly* from here -

http://forum.xda-developers.com/htc-one/general/lollipop-ruu-zip-small-collection-t3053944

Find your download for version 7.21.707.5 and CID HTC__044 - it's there.

You can see that I matched those from your getvar all results.

Make 100% sure that you have the right version, that you have the htc_fastboot indicated by the instructions, and just follow the instructions.

Make sure that your phone has a 50% charge or better before trying it.

If anything can fix your phone, it's that.

Sorry but the cid for version7.21.707.105 does not match. On the website the cid is htc_ _ 38 and mine is htc _ _ 44. Is it fine?
Click to expand...
No, it's not fine at all.

Match the CID - you can see I recommended the later version number (point 5 is greater than point 105) based on your getvar results.

It should be OK.

htc_fastboot oem rebootRUU
ok

but when i tried to flash the zip file using the command line below its says failed.

htc_fastboot flash zip RUU.zip

Capture.PNG


any idea ?
 
Hmmm...

If someone gained s-off to the bootloader and followed the very bad advice to return it to s-on, or much worse, the bad advice to cover it up by editing the bootloader, then the phone may be in an undetermined state and beyond hope.

Try this and hope for the best - go to normal FASTBOOT USB mode and say

fastboot oem lock

If it says it's successful, try the RUU flash procedure again.

After that, I'm completely out of ideas.

already tried .. it says its already locked..
do you think its a hardware problem??
 
The bootloader and/or recovery is scrambled.

You'll see in your getvar output that it says security is on, otherwise known as s-on.

If that's true the phone would have protected itself from a bad RUU flash attempt.

So that takes me back to wondering if s-on/s-off/s-on was tampered with before.

Or - it's just on its way to a more complete hardware failure.

I've seen Motorolas do what yours is doing - never thought I'd see an HTC do that, and as you can guess, I've done a lot with HTCs.
