[One (M7) Q&A, Help & Troubleshooting] bkhosh2:
Hi guys,

I've searched the entire web (including all the XDA links regarding the HTC One), tried every solution out there and still can't fix my problem. I don't know where else to turn, so I am creating a new thread in XDA Developers.

Originally, I had unlocked my bootloader and rooted the phone to use stock android. A couple days ago, I tried to re-lock the bootloader and change back to the original Sense UI; however, when I did this, I got stuck in a boot loop (the phone kept rebooting and didn't boot into the OS).

I then went back into fastboot and restored all the files and settings.

Now, the only things I can actually go into is fastboot and bootloader (cannot boot into OS or even see the boot screen). The only way the phone can connect to my PC is if I'm in fastboot. When I go into bootloader, the phone disconnects from my PC.

My phone is from Telus in Canada and I can find a couple .zip RUU files on the web for Telus, however when I try to flash the phone using the command "fastboot flash zip filename.zip", I get the error "signature verify fail."

When I tried to use the RUU.exe from BrightStar (developer version), the update failed and there was a message saying to download the original firmware.

The last thing I tried was the command "fastboot oem rebootRUU" (I did this to change the CID and MID, so I could use the Google Play RUU). When I do this, it goes to a black boot screen that has the HTC logo in grey (this is the boot screen I got from trying to use the BrightStar RUU.exe. It was originally a white screen with the HTC logo in green.). When I'm at this screen, I can communicate with the phone using fastboot commands, however when I try to change the CID, I get the error: "status read failed (too many links)," and when I try to change the MID, I get the error: "Command error !!!"

Just to remind you guys, I can only communicate with the phone using

fastboot commands

. No adb. :(

I have officially given up and gone crazy! Please Help!!! :eek:

UPDATE

* - Sorry, forgot to mention that I've idiotically re-locked the bootloader. Unlocking the bootloader would probably get rid of the "signature verify fail" message. I'm unable to flash the recovery because the bootloader is locked and I can't get into the filesystem because the phone needs to go into the OS for that.

When I try to unlock the bootlader by using "fastboot flash unlocktoken Unlock_code.bin" it gives me the error: "cannot open 'Unlock_code.bin'."

I need to be able to access and make changes to the file system by using fastboot commands and I have no idea how to do this.

UPDATE #2

* - I've managed to re-unlock the bootlader (I didn't have the Unlock_code.bin file in the same directory as the current directory in my cmd window). I've re-flashed the recovery successfully. Now when I reboot, it goes into recovery mode (still can't boot into the OS). I'm using ClockWorks for the recovery.

Now I'm unable to root the phone. I'm trying to write SuperSU v1.65 to the phone by using the command: "fastboot flash zip UPDATE-SuperSU-v1.65.zp" and I get the error message: "remote: not allowed."

I can flash the recovery.img and boot.img (can't flash system.img because there's "not enough space"), but I can't flash .zip files

When I try flashing another boot.img, I still get the same thing. The phone goes to the boot screen and can't boot. Then, it reboots and goes automatically into recovery (I can still get into the bootloader and recovery).

Any suggestions to get past these permissions?
