Help :)

I'm trying to return my old HTC One XL (Telstra) back to stock. It's current state is:

S-Off
CID = 11111111
TWRP
hboot: 2.15

I've found the latest full RUU from this thread (all the links to newer RUU are broken):
http://xdaforums.com/showthread.php?t=2119610&page=5

3.17.841.2
File Timestamp: 04/12/12
Publically Seen: 24/12/12
Android: 4.1.1
Kernel: 3.4.10-g240d4d5
hboot: 2.14.0000
radio: 0.23a.32.09.29_10.128.32.34a

First, can I us this RUU even though I have a newer hboot (2.15) installed?

Second, do I need to change my CID back? (using fastboot oem writecid TELST001). Will changing the CID loose my S-Off?

Third, is this the process:

1) Flash the stock recovery:
fastboot flash recovery recovery.img (taken out of the RUU)
fastboot reboot-bootloader
fastboot erase cache

2) Flash the stock boot.img
fastboot flash boot boot.img (taken out of the RUU)
fastboot reboot-bootloader
fastboot erase cache

3) Re-lock the boot loader
fastboot oem lock
fastboot reboot-bootloader
fastboot erase cache

4) Load RUU
fastboot oem rebootRUU
fastboot flash zip ruu.zip
fastboot reboot

After all this, I assume I'll loose TWRP etc. but will have a stock phone, and the ability to load OTA updates from the carrier.


THANKS :D

That 3.17.841.2 file isn't an RUU, it's an OTA. It's a zip file, an RUU is always an exe program. There's only one Telstra RUU available and it's a much earlier version. You can't flash that file using fastboot, an OTA can only be applied via stock recovery, and it requires the correct previous OS to be already installed on the device. If you want to return the device to stock you just run the latest actual RUU (1.89 from memory), and follow this process:

1) Run RUU exe via Windows.

2) Revert to Telstra CID.

Code:
fastboot oem writecid TELST001

3) Lock bootloader.

Code:
fastboot oem lock

4) Go back to s-on.

Code:
fastboot oem writesecureflag 3

5) Take OTA updates via Settings/About Phone/Software Updates until you reach the point you wavy to be at.

Won't running the exe RUU before changing the CID fail?

And I thought you could still get the RUU as a ZIP (although most are just smaller OTA updates). The ZIP is 700Mb.

No, you have s-off. Having s-off bypasses all security checks.



No, an RUU is always an exe file. Just like an OTA is always a zip file.

Sweet, cheers timmaaa :).

Now, I just need to find the RUU, all the links are either broken, or to the HTC website which has gone.

Any suggestions?

And would I need to downgrade HBOOT before RUU?

    You'll find the RUU here:

    http://androidruu.com/?developer=Evita

    You don't need to do anything before running the RUU, just connect in fastboot mode and get it cracking.
