It's HERE
Might be useful to anyone who has rooted and accidentally upgraded their hboot and now need to downgrade for warranty return.

Really useful for me to sendback my Desire to HTC !

Why are you posting a pointless procedure in an old thread? The latest T-Mobile RUU will work on 0.80 as it has 0.83

[INFO] Downgrade HBOOT 0.93 to 0.80

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).

[Q] HTC Desire with HBOOT-0.93.000001

Hello,
I had an hardware problem with my Desire (problem with volume "-" key), so I made an echange.
On the new one, I'm already on orange rom with android 2.2 and hboot 0.93.000001.
Before I were in hboot 0.75, I was sure that I have an Amolex Desire and not an SLCD so it happened that after making him reflash orange rom (but at this moment, I didn't exchange my phone finally), I re downgrade the hboot to re put the 0.75 for re rooting it, because I was sure that it was to 0.75 by the past.
But I read that if I have an SLCD, i've to be careful and I'm afroid of SLCD Brick as described in aanother thread?
Do you advise me to root it with the last version of unrevocked without investigate to know with downgrade to 0.75 and knowing if it's an Amolex version?
Thanks
There is NO need to downgrade.. 0.93 is rootable from unrevoked use 3.21
And I think S-LCD brick is not due to root.. but it is due to wrong RUU flash.
Someone correct me if I am wrong.

So it is.

Can Hboot 0.93 be replaced with alpharev Hboots and s-off like the previous Hboots?

Yes, it can.

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] Unrooting HTC Desire

Hi, apologies for creating another thread for something that is probably very simple, but the information I’ve found can be conflicting sometimes
I've a rooted HTC Desire with a (very old) LeeDroid ROM installed.
Phone is going, so I want to revert back to the office UK T-Mobile ROM.
Current configuration:
Bravo PVT1 S-ON
HBOOT - 0.80.0000
Radio - 5.09.05.30_2
Clockwork Recovery v 2.5.0.7
I've never messed about with S-OFF or anything?
Is it simply a case of getting the correct RUU (which I think I have, RUU_Bravo_TMO_UK_1.21.110.4_Radio_32.36.00.28U_4.06.00.02_2_release_127570_signed) and running it?
I realise that this is probably a stupid question, but any assistance would be appreciated?
Thanks
Put the 2.2 one on, not the 2.1
http://shipped-roms.com/download.ph...00.32U_5.10.05.17_2_release_143754_signed.exe
Or better yet put the unbranded 2.3.3 from htcdev.com.
I'm not 100% sure, but I think you need to install a rom with sense, plug USB in HTC Sync mode and then run the RUU.
Then the official RUU should take care of everything (boot, radio).
But again, never done myself.
Thanks guys, installing the official RUU from the website worked perfectly
Thanks for the advice
