Well it seems that i am just out of luck. It turns out the RUU that I will be needing 1.29.720.11 is not yet available for download


I do have a Nandroid backup of my stock rooted rom if it will work somehow

That's all you need.

I encountered the exactly same problem as you did. HTC replaced the main board and battery for me, problem solved. Hope this helps

I have the same phone. I have a nandroid backup of the stock rom. Don't know if that'll help you.

Thanks for the offer iTeeXDA, but i managed to get back to stock(using nandroid backup). The issue seemed to be that i had named the folder of the backup rom(no spaces).

Now what should i do next? I imagine i should be reflashing stock recovery right? Then relocking the bootloader? Will i run into issues cause i came back to stock from a nandroid backup?

EDIT:So, ok, i went back to stock recovery and relocked bootloader. Phone keeps booting into hboot after i relock bootloader. I've unlocked the bootloader again and the phone seems to have booted

If u can't see anything then HTC people also won't be able to see anything..so go ahead with the phone as it is..n as somebody has already told u that they will be replacing your board the firmware is gonna be gone anyways..I guess I am correct here ...
N this is India man..here HTC people cannot even tell the screen resolution of the phone..forget about the bootloader..happened with me when I took my Note to Samsung ..

Unless they DO replace the screen and boot the phone finding the bootloader unlock then charge for the repair haha. Doh. Let's hope not.
