Hi everyone.

I've read many topics about custom roms (xda develop.) and i'm still not sure if will it work. I don't want brick my hd7

Device: HTC HD7
System: 7.10.8107.79 (MANGO ?)
Firmware: 2250.21.51101.207 (cid 207= o2 DE)
Hardwarerevision: 0002
Bootloader: 5.11.2250.0 (134400)

PD29100 SS-BC (4K)
SPL-5.11.2250.0(134400) MNG
MicroP(LED) 0x07
TOUCH S1(v1.8,#1624)

I would like to have inside my hd7 Deepshining v7.6 - "if you have mango then you have to downgrade bootloader 4.xx or 5.xx with NODO.."
Ok but there are only one zip rom for cid 401..

After research i've found a topic - [NoDo ROM]HD7_O2_DE_1.69.401.01_Radio_5.54.09.21_22.33b.50.1 0U_NoDo, by ansar
But i'm not sure if i can with these 2 zip rom file downgrade my SPL

RUU_Schubert_O2_DE_1.69.401.01_Radio_5.54.09.21_22 .33b.50.10U_NoDo_Signed_by_ansar

After that i need to install RSPL and HSPL.

At the end i can flash DeepShining ROM.

It is correct ?

what % dose it get to?
after each try go to bootloader and check tri screen as it might still downgrade HSPL


let us know how you go

how long have you had the phone for?
would you have a restore point in zune, as that the best way to go back to a earlier build and no download reqiured.

have u had a look in here...http://forum.xda-developers.com/show....php?t=1427890
football has 3 diff roms

cheers and have a gr8 day

SPL & Firmware
Hi Chotu

I have the exact same specs as you have same HTC HD7 everything the same.

I was researching a lot but still had no success finding a concrete fix for this.
Still searching for an answer.This thing is unbelievably risky man. We could remain
with a cold brick in our hands

Anyway did you have any success downgrading the SPL? New tips that worth trying?
