Any update on this unbranding possibly working for the Verizon HTC 8X?

Thanks!

I've got a pre-production unit that I'll be trying this on if i can't find anyone interested in buying it or swapping it for a retail unit.

got it working!

thank you very much for flash-information, the rom files and tutorial! after a several tries i finally got it working! i unbranded my t-mobile htc 8x (uefi bootloader 156246). needed to flash things some more times and there were moments where my heart nearly got stuck! i think cause was my crappy self-made y-cable! one time i had short-circuit and my pc crashed - got luck, wasn't flashig at this moment!

+1 on this. The Verizon 8x bootloader version is lower than what's specified in OP, however I'm curious to know if there's any other issues with unbranding the Verizon version. Any insight OP?

I just swapped out my pre-production unit for the VZW version (couldn't bear to flash a stock ROM and ruin a test device, when many people here would love to get their hands on it.) Anyway, I've got my AT&T SIM in, and everything works but tethering (my most important need).

I've got the parts to debrand, but am also waiting for someone more bold than I to try it first.

does tethering now work without having a tethering plan?

Hi at all,

i have now a brandingfree HTC 8x

base was the following rom and bootloader:
german o2 firmware:15232.20.20002.207
bootloader: 0.0.1532.20(161722)

very very good guide in first post...

you need only this:
http://www.amazon.de/gp/product/B00...s_o00_s00_i00?ie=UTF8&psc=1&tag=pocketpc0d-21
http://www.amazon.de/gp/product/B00...s_o01_s00_i00?ie=UTF8&psc=1&tag=pocketpc0d-21

but two difference on my own...

1.
the message
display after step 8, NOT after Step 7
with error UEFI for Key Provision ONLY

2.
i have flashed in step 9 again the "ruu_signed.nbh" named as "ACDUDIAG.nbh" (same as step 1)

i've got 2 error messages at the end of flashing process...

- first
firmware update for touchscreen firmware failure
(but Touchscreen works well???)

- after step 9 complete, HTC8X boot to boot loader and display the message
UEFI for Key Provision ONLY

3. now i have rebooted device and everything works fine...

notice with restore:
if you will be restore your backup-settings, device will be fall in a boot-loop after HTC-Logo, next Display is black and then come the loop...
only help was a "hard reset"...

thanks for this great tutorial...

Need Help!

I'm not sure what I may be doing wrong, I followed the instructions to a T. On the first flash step, when the phone boots up, it boots to a white screen with green text, showing the software info. I never get the ACDUDIAG.nbh name to pop up, or the flash to start. My usb drive does start to blink, like it's being read. I have done md5sum checks on my files to make sure they're good. I have a T-Mobile HTC 8X, fresh OTB, no updates ever done. Any suggestions?

phear86 · Feb 25, 2013

Currently, I do not own a Windows Phone 8.x device; however, I do own a pair of HTC Titans (Eternity) that I successfully debranded and HSPL. The process for debranding the 8X is almost identical to those of us who have/had the Titan (Eternity). For all of you new to this, I would encourage you to read the Titan debranding at http://xdaforums.com/login.php?a=pwd&u=1203383&i=e7e7df4e5dae3f4b12d23df7ca7aef94df815cb6 . The filenames are different but the steps are the same. All of you who are in your first Windows Phone platform device, please take the time to read these threads before repeatedly asking us what to do and how to do. Those of us running around with HSPL'd Titans know this is by far not a perfect process and is highly dependent on where you bought your device and where you're from and what carrier. I bought my Y-cable from Amazon and used a PNY USB 4 gig thumb drive; don't skimp, do it right but be patient. Until Microsoft gets Skype baked into WP8.x and it works without a hitch I'm staying put, but that's me! All of you please be patient; take care!

I'm in the exact same situation.
I have a Verizon HTC 8x "Unlocked" bought in the Microsoft Store in Las Vegas.
Firmware version: 1532.20.10110.605
Bootloader: 0.0.1532.20(157404)

When I plugged the USB drive it started blinking and stopeed after 4-5 seconds. Then I keep pressed the camera button, Plug the HTC to the micro USB port and then I recieve a white screen with green text showing software info, so I couldn't complete the first step.

Any sugestions?

Thanks!

Update: I've tried with a different pendrive formated in Fat32, and now after the green text I'm getting 3 lines with codebars (IMEI, SN, MB) and after the last codebar in the center the text USB, but nothing happens...

How exactly did you format it? I wanted to see if you did it differently than me, or on a different Windows than me. And btw, I don't think this will work with the Verizon one because it's completely different hardware, that one is a dual mode phone, but the European one is just gsm.

I've performed a quick format in FAT32 file system (right click -> format in the drive in Computer Window). I'm using Windows 8 x64 Enterprise.
Sad news about that this won't work with the Verizon model.
I'm from Argentina and I bougth this Phone in a Business trip. The guys from the MS Store told me that it was fully unlocked, but when I get back here to Argentina and inserted my micro sim card, I've noticed that I couldn't use some features that I was able to use in my previous Win Phone 7.5 device with the same chip. I think that the worst issue is the internet sharing blocking thing.

My suggestion would be to save your time and not try it

No american ROM has been extracted yet. And the European ROM shouldn't work on your device.
