[INFO] Downgrade HBOOT 0.93 to 0.80 - Desire General

Hi All,
I just wanted to share this info from personal experience. I am using HTC Desire (AMOLED/ASIA Region). I updated OTA Froyo then decided i wanted to root my phone. Rooting requires 0.80 HBOOT so i need to downgrade mine from 0.93 since it got updated also during OTA update. I used teppic's tool (thanks very much for the help as well!) to downgrade my HBOOT from 0.93 to 0.83. Afterwards, i installed signed_RUU for Asia region and now my phone is back to HBOOT 0.80.
This is very helpful especially to those who wanted to bring their phones back to HTC for any repair/warranty concerns.
Hope this can help all my fellow noobs out there as it did to me! Now i think i can try rooting my phone!

thnx for your topic! found via Google and i really helped me!
i need my desire back to stock so i can send him in for reparation. Tried different RUU's but they all failed because the newest bootloader (0.93) this tool worked for me!

It worked for me. Salamat po kababayan

Well it works for me till i downgraded my hboot to 0.83 can u elaborate as to which ruu u installed from the asia region as i tried and it didnt downgrade my hboot
(i need 0.80 as unrevoked doesnt work for me some communication error )

Yes, it's worked perfectly.
Thanks so much (also to teppic74).

I have a HTC Desire with HBOOT 0.93 rooted with unrevoked (I bought it with no branding) and now I want to unroot it. I tried several methods, but all of them failed, so I need you to recommend me a working one plese.

Htc wildfire hboot 1.000.002

Hello guys!!!
I dont know if i post to the right place!(This is the first time i post a new thread)
I have an hTC wildfire with hboot version 1.000.002. I wanted to root with alpharevx but now it seems they removed the 1.02 hboot version for htc wwildfire from their site... , is there any way to downgrade from 1.02 to 1.01(my phone is nto branded)
Please help mee
Thanks in advance!
There are two things you can do:
1) Try on HBoot 1.01.0002 itself. There are cases when it works.
2) If that fails, the procedure to downgrade to 1.01.0001 is posted here:
http://forum.xda-developers.com/showthread.php?t=1132028
thank you for your reply!
I will try the first method but the second link is only for branded devices,isnt it?
Nope, Its universally applicable for all devices on HBoot 1.01.0002
Thank you very much!!!
One more thing!
Do i have to do the step with the goldcard???
If you are following the guide to downgrade the HBoot, Yes, you have to.
A bit difficult but i will give it a try...
As I said, try running AlphaRev X directly without downgrading first. If it works, it's well and good, else, you have no choice but to go for the downgrade procedure.

[Q] Deeply confused by unbrick attempt - can anyone help ?

Hi All,
Apologies in advance... I'm a noob.
Well for a long time I was a happy camper running the excellent Marange MIUI ROMs on my HTC desire (which had been replaced by a PVT4 motherboard version). This was S-OFF and running HBOOT 0.93... but then one day a couple of months ago I got into a boot loop where all I got was the MIUI boot logo... not really a loop more just stuck at the logo.
So I tried several clueless attempts to reimage using the TeamWin TWRP boot loader... but nothing I did worked. So after several failed RUU attempts and random PB99IMG boots and one successful run of:
RUU_Bravo_Telstra_WWE_1.15.841.14_R4_Radio_32.30.00.28U_4.05.00.11_123851
I had what I imagined was a stock phone running an ancient Telstra release (it is a Telstra branded phone - the other world wide English RUUs refused to recognise the phone - 130 error).
I tried re-flashing the baseband radio, ClockworkMod v2.5.0.7 Recovery and MIUI... and wound up back to square one stuck in the MIUI logo and the RUU I used to get back to stock is now refusing to do anything) and this time I noticed my phone reports:
BRAVO UNKNOWN SHIP S-ON
HBOOT 0.75.0000
MICROP-051d
TOUCH PANEL-SYMT0101
RADIO-5.17.05.23
Mar 5 2010, 21:12:15
So somehow my PVT4 S-OFF 0.93 changed to the above. Which I don't understand... I thought that only a Goldcard could do something like that. None of the recovery tools seem to want to deal with HBOOT 0.75 and the fact that I'm S-ON would appear to be a pain.
The other thing that really confuses me is that how come if the phone is S-ON it lets me wipe everything and install the latest Marange MIUI ROMs ? Surely if it's S-ON then these would have to be signed (maybe they are for all I know).
Finally, if I use adb when the phone is stuck in it's MIUI boot logo I'm amazed I can get a root shell.
Anyone got any advice on how my phone got into such a mess, how to fix HBOOT and get a decent ROM running again ?
Any help hugely appreciated. The more detail the better.
Many AtDhVaAnNkCsE
Cheers,
Doug

How where you s-off, with hboot 0.93? Alpharev hboots have 6.93 etc.
Anyways, did you try the 2.3 RUU? Check my sig.
You can flash roms with s-on, but you can't change recovery.

To be honest I couldn't quite remember the state of my HBOOT I just new that it had been newer than 0.75, possibly 0.80, and that I had S-OFF and PVT4.
Your suggestion worked perfectly! I ran the RUU without issue to upgrade to 2.3 which gave me a new 1.x HBOOT and then I ran revolutionary and was then able to install MIUI. Smooth as...
Thank you so much!
I find the howto guides out there have lots of how but not too much why. I like detail on why things work or don't. Like why did that RUU work when so many others I tried didn't... did HTC make RUU 2.3 more forgiving in it's identification of supported phones ?
Anyway, once again many thanks for your kind help.
Cheers,
Doug
