Downgrade 7720 RTM to Nodo? - HD7 General

Hey Guys,
i'm currently running 7720 on my HD7 (forced update through Zune) and now I wanted to install HSPL and flash a Custom rom. But i read that if you install HSPL on Mango, the device will brick. Can i downgrade the device using Official HTC Rom to Nodo or Stock rom?

http://forum.xda-developers.com/wiki/index.php?title=HTC_HD7/Shipped_Roms
here is Stock rom..
Good luck..

no need to flash NoDo ROM...
just flash the SPL_Signed.nbh from the RUU of an NoDo for your device.
much quicker and saves the ROM.
i suggest task 00 for flashing only the SPL_Signed.nbh.

[Q] Help restore stock SPL

Hi all,
i'd installed Touch-IT Rom, applying HSPL, just to have Mango.
I'm not really insterested in Custom Roms, and now that Official Mango is out, i want to revert to Stock NoDo Rom and than let Zune update my HD7.
I downloaded RUU_Schubert_HTC_Europe_1.16.401.01_Radio_5.51.09.06a_22.30.50.09_Signed_SCHUBERT_RELEASE.exe.
Can i launch directly this exe to revert SPL to stock, or i have to do something else to restore SPL?
Thanks.
EDIT: Restored simply by installing Official RUU in bootloader.

[Q] Help with Chevron/unlocking mango?

Hello, new to 'hacking' the WP7 but i want to flash a custom dev unlocked ROM to my phone, but i want to make sure i dont use the wrong ROM, so i was hoping someone could point me in the right direction?
I have a HD7 (T Mobile unlocked, US model, i'm in the UK if that makes a difference, also using o2)
It's currently running the official mango by the disconnect internet trick in zune.
Thanks in advance!

any Schubert ROM will flash successfully to your HD7 with RSPL or HSPL installed.
with that said...
is either RSPL or HSPL installed?
if not... you will need to get that. DFT's RSPL/HSPL.
and here is a little how-to if you have the wrong SPL. see steps 2 and 8.
after that,
any ROM in the HD7 WP7 Development thread should flash fine.

Thats great thanks! just a few questions for you..
RSPL or HSPL? (sorry new to this ^^")
So if i install a nodo ROM (considering i'm currently on Mango) will it just roll back with no problems?
do i need to do anything specific with these ROMS that have different radio software versions? or can i just ignore them?
I'm trusting if i use the backup tool i can restore my text messages etc again, i dont really feel loosing them. :/

RSPL is, basically, a temporary SPL, which returns to OSPL (stock SPL) after reset.
HSPL is 'permanent' until you flash another SPL or return to stock.
both allow you to flash a custom ROM.
if you flash a RUU_Signed.nbh from a NoDo ROM it will 'roll back' fine, but will erase all data currently on the device.
but if you just flash the SPL_Signed.nbh from a NoDo ROM, it will only flash the Radio and SPL. i recommend task00 to flash this.
unfortunately, through Zune, SMS doesn't get backed-up.

I've managed to roll my phone back using the zune software, i didnt know that was a option, so now it's back to NODO but with the problem of my SPL is set to v4.5 and the link you sent me here takes the SPL to 4.05 if i'm reading it right.. but DFT RSPL only goes up to 3.4... so have i hit a dead end completely? :S

nope. not a dead end.
quickest fix.
01. visit HD7 Radio Wiki, link in my signature.
02. download a stock NoDo or Pre-NoDo Radio for your device.
03. extract the SPL_Signed.nbh from the 'stock' folder.
04. flash SPL_Signed.nbh with task 00.
05. SPL has now been rolled back.
from there...
06. flash RSPL.
07. flash HSPL, if desired.
08. flash newer Radio, if desired, using RUU_Unsigned.nbh from desired Radio.
09. flash Custom ROM of choice.

i unfortunately don't know.
best bet, is to ask the question on that thread.
i haven't ever tried using it to back up my device.
actually, i haven't ever backed up my device before.
too busy constantly flashing and testing my intrinsicROM.

For custom roms I need to install hspl? Shipped roms I can install with original spl?i heard that you can easily brick phone by install custom roms and hspl,is that true?

yes, Shipped ROM can be flashed with OSPL, as long as the vendor id's match.
phone can be half bricked if you try and flash RSPL/HSPL onto an unsupported SPL, yes.
if you want to go the Custom ROM route, i would...
01) flash a stock Shipped NoDo or Pre-NoDo ROM.
02) flash RSPL or HSPL.
03) flash Custom ROM with task 29.
04) flash desired Radio with task 00, if desired.

what is vendor id?
and how to know if that id's match?
also what is better,hspl or rspl?

well, if the vendor id's don't match, the flash will fail.
ie. flashing a TMOUS ROM onto a HD7 T9292 will fail, etc.
RSPL is a temporary SPL which will return to OSPL after reset.
HSPL isn't temporary.
both allow one to flash Custom ROMs.

HTC HD7 - back to "official" ROM

Hey Guys.
I've been using the Deepshining ROM for the past lets say 8 months.
Right now I'd like to get back to the "official" one, they were called "STOCK" ones, right?
I haven't been into flashing and so on for the duration I mentioned above, so I'd appreciate any help.
Which one should I download, to get the newest official one?
How should I flash it?
Do I have to flash it using the tutorial?
Where can I download the orginal ROM?
yes make sure u use a stock rom that is nodo version and below and a bootloader which is supported under DFT RSPL/HSPL
if u flash any mango rom that have bootloaders 4.5 and above , yr device is "updated" and u cannot downgrade again.

Just one question, if I use a custom rom and I don't like it, with the goldcard method will the phone go back to the original SPL without RSPL/HSPL?
I want to know before trying a custom rom.

The goldcard method allows you to downgrade the devices SPL. Which needs to be at or below 3.xxx to install RSPL/HSPL.
After the SPL is downgraded then you install RSPL/HSPL. Which allows you to install a custom rom. The custom rom is flashed by entering the device into bootloader mode then connecting it to the PC and running the RUUwrapper provided with the rom.
If you install only RSPL and flash a custom rom the RSPL is reverted back to OSPL after the flash process. So then to flash a different/new rom you have to re-RSPL the device and then flash the rom.
If you install HSPL then you just have to put the device into bootloader mode and flash the new rom.
HSPL is much easier and can be reverted back to OSPL by installing a stock/shipped rom.

[Q] Nodo but bootlader is 5.11.x.x ? how?

Hi,
I wanted to install that http://forum.xda-developers.com/showthread.php?t=1271118
but it is written that I should downgrade to NoDo . So I had my Nodo back up. I did that using Zune.
my phone is showing version 7.0.x.x which is Nodo but my bootlader version is still 5.11.x.x.
how this is possible? does it mean that even bootlader version is 5.x, if I have nodo, I can continue installing RSPL/HSPL?
EDIT: I have just learnt that Nodo restore doesnt restore the bootloader version.
I am going to downgrade to 4.x with this method http://forum.xda-developers.com/showthread.php?t=1362194
but I am wondering, can I downgrade from 4.x to 3.x?
because in order to install that http://forum.xda-developers.com/showthread.php?t=1271118
I need to have SPL less that 4? isnt it?
thanks for your help
Yes if you've already restored your device to NoDo through Zune then you will still have SPL 5.xxx, the restore doesn't downgrade the SPL.
What downgrades the SPL is the re-update process. You have to re-update the device to Mango again. The key here is that when updating to Mango the device will reboot twice, once to downgrade the SPL to 4.xxx and once to install Mango...You have to stop the update process after Mango is installed and before the next update is applied which is the HTC Firmware Update. If that's installed then the SPL is upgraded to 5.xxx again.
After the Mango is installed and the SPL is downgraded to 4.xxx you can the flash a Pre-NoDo/NoDo rom to the device to downgrade the SPL to at or below 3.xxx (which is required to install XSPL = RSPL/HSPL)
One the SPL is downgraded to 3.xxx or lower you can Install XSPL
http://forum.xda-developers.com/showpost.php?p=16189671&postcount=1
After you install XSPL to the device then you can flash a custom rom of your choice.
thank you i have finally succeeded but it is really a hard process.
