[Q] downgrade and radio

Keep original version of Radio when downgrade? Or overwritten by new ROM image?
( downgrade by thread http://forum.xda-developers.com/showthread.php?t=905003 )
I have official Gingerbread OTA, so hope i have newest official Radio.
I want keep this Radio, then use Radio S-OFF guide (not bootloader ENG S-OFF) and install custom ROM.

As far as i understand it, if you don't use the ENG-s off you won't be able to flash new Radios, which is recommended by most Chefs for best performance. But someone feel free to correct me

WHEN YOU flash any custom rom only re-writes kernel and rom
you´re going to keep your current radio mate
in adition for root your device with gingerbread 2.3.3 read about "gingerbreak method" you need it for obtain root access.

what is your build number i.e. Firmware?
if its lower than 1.7x just do ENG-OFF straight away...go HERE
if its 1.7x or greater, you need to downgrade first ... go HERE -- (downgrade, then root again to flash new ROMs -- use Visionary)
--When downgrading, you dont need to follow the whole thread since you're already rooted, and the thread explains how to get temp root to flash 1.32 RUU. so just skip to the part when you have to flash the RUU.
For 1.32 RUU, it can be found in the downgrade link.
For more things like ROMs, RUUs, Kernels, etc ... go HERE

firmware, RUU confused

I have followed this guide to root my 1.72 DZ. Then I flashed it with Arabic RUU which contained a 1.83 firmware and I lost root. I decided to root again and install ROM manager so I followed the steps again with the PC10IMG.zip and I found out that I lost the Arabic and back on WWE software.
I want to have my Arabic RUU and rooted phone

My understanding now is:
The image will contain both the firmware and the Android, so there is no way to downgrade the firmware and keep the rest.
I stand corrected

[Q] Hboot Downgrade necessary for firmware Reset??

Hello,
because of Warranty issues i need to install the genuine Vodafone RUU on my Desire, at the moment my Desire(Amoled) is S-Off and the Alpharev Hboot Version 0.93.0001 is installed (Stock Paritition Layout), the question is is a downgrade necessary before i install the Vodafone RUU??
Greetz Neewes

Yes, just flash the Alpharev Downgrader, then run the RUU.

Downgrade from 2.3.3 to 2.2?

How do I Downgrade to a EU build of 2.2? Just RUU? Im on official 2.3.3 now.

If you want to go to a different RUU from the 2.3 RUU then you may possibly require a goldcard if the cidnum are not matching.
- The cidnum in the RUU are available in the android-info.txt whereas the cidnum hardcoded in your device is retreived by giving command
Code:
fastboot getvar all
- If they match you dont require goldcard. Else your sdcard needs to be a goldcard.
- Dont select a old RUU which will blast you back to eclair.
But any case I dont advise going to any RUU just like that. Its dangerous coz it plays around with radio and hboot which are both permanent brick potential. 2.3 RUU is safe.

Dont try a different ruu untill u find out for sure it will work because im pretty sure u can NOT downgrade using an ruu. I could be wrong but im fairly sure im not. :sly:

So how do i downgrade? With PB99IMG? Do i need to s-off? My CID is the unbranded EU one (HTC_E01 or something, idunno).

You need to first S-OFF with revolutionary. Then flash the downgrader from alpharev. Then flash either a RUU for your network provider, or the WWE RUU (however you need a goldcard if you want to use the WWE RUU as it de-brands your phone).
If you need help on how to use revolutionary, or flash the downgrader then look at my guide.
For revolutionary look at "S-OFF'ing problems" and for flashing the downgrader look at "flashing HBOOT/SPL"
This is a quote from bortak in a previous post. Thank him

The OP seems to already be on stock hboot SON with official Android 2.3.3. So if he wants to run a RUU imo he doesnt need to follow the revolutionary and downgrade path. What is the point of that ?
I dont know why you want to downgrade but:-
- Which RUU are you planning to run ?
- What are you trying to achieve ?

Well ur opinion is wrong then. U cant downgrade using a ruu, simple as that. S-off with revolutionary only takes 5 mins so why not go the s-off root

The problems that can occur downgrading from factory 2.3 are:
-problem overwriting hboot (newer release)
-problem overwriting radio (newer release)
Best way to downgrade is to gaining s-off, flashing Alpharev downgrade and radio.img from desired RUU via fastboot, and then running Desired RUU. The appropriate RUU to be used should be 2.2 WWE RUU cause I couldn't find any FroYo release that is for HTC_Europe (all are Eclair releases).
One more important thing is version of device (amoled or slcd) cause running a wrong RUU can cause screen failure, so repair is a little bit heavier (like playing table tennis in complete darkness ). So I suggest to find the newest FroYo release (reference is the latest version number of release and radio).

SO i ran revolutionary, tried to ruu but resulted in hboot error. I flashed bravo_downgrade.img from alpharev.nl and now my hboot is S-ON 0.93.something. So now i should:
S-OFF again using rev
Flash radio from ruu using fastboot
Flash bravo_downgrade.img using fastboot
Flash hboot from ruu using Fastboot.
Now run the RUU.
Right?
