Hboot downgrade - Desire Q&A, Help & Troubleshooting

On the alpha rev sire Theres a bravo downgrader. Any 1 know if it's new for the ruu or if its old

hbbot downgrader sould be flashed before you run ruu, in other way you will stay on s-off

yup, just to add to that.. Alpharev's HBoots are made so they cannot be overwritten by other HBoots apart from Alpharev ones, therefore if you flash a RUU and you don't flash the downgrader, you will have a stock, unrooted ROM, but still Alpharev S-OFF. The Alpharev downgrader "Unlocks" The HBoot which allows it to be overwritten by the HBoot from the RUU.

Yeah because that was a newer Hboot.. basically, if you notice the difference between the stock S-ON HTC Hboot and the alpharev one is the version
Stock: 0.93.0001
Alpharev: 6.93.1002
That's why when you flash the RUU it doesn't overwrite the HBoot.. because naturally it won't downgrade it, however the new 2.3 RUU has a newer hboot which is a higher version than the alpharev one, hence it has overwritten it.
Or at least that's the way I understand it..

Issues after running RUU

I did run RUU_Bravo_Froyo_HTC_WWE_2.29.405.5_Radio_32.49.00.32U_5.11.05.27_release_159811_signed RUU. (unbranded desire)
Looks like everything worked fine, i had no errors whatsoever, system is booting fine but:
1. i'm still S-OFF
2. my hboot is 6.93.1002 (i was cm7r2, but i did run downgrader and flashed stock hboot)
3. radio is 5.11.05.27 (it keeps scanning when i turn it on, and i cannot connect to WIFI at all, it see my channel and others but just wont connect)
What's wrong?
Edit:
I fixed WIFI issue, point 1 & 2 are still to fix any ideas?
Edit2:
After flashing downgrade.img again the hboot is 6.93.9999 now.
you seemed to do everything correctly, okay, flash the stock bravo HBOOT from alpharev, then flash the downgrade utility. Extract rom.zip (you know how to do that right) from the RUU, and then extract the HBoot.nb0 file (from rom.zip).
Once you've got that, put it in a zip with the android-info.txt file and name the .zip file PB99IMG.zip... this is EXACTLY what I did and it gave me the stock S-ON Hboot Then obviously put it in root of sd
Try that, hope it helps
EDIT: sorry I dunno why I gave you that info.txt when it's in rom.zip as well :s and just remembered it won't work for you since it for Vodafone :L ahh I'm an idiot sometimes
You need to flash downgrade HBOOT in order to go S-ON.
I did even twice, prior to flashing stock hboot and also after RUU did it job, went back to see if i'm still s-off. Was still s-off so i flashed downgrade.img again but still s-off and alpharev hboot (6.93.9999)
I will try what bortak suggested though.
yeah when you flash the downgrader it wiull say "Alpharev Unlock", and HBoot version is 6.93.9999
Try the method I told you about, worked for me.
okay I just realised what you did wrong.. you said you flashed the downgrader BEFORE you flashed bravo_stock, which means you still had a normal alpharev Hboot which could not be overwritten. You need to flash the downgrader THEN run the RUU, without any other steps in between. (or again, you could just flash the stock HBoot.nb0 that you can find in rom.zip with the android-info.txt in a PB99IMG.zip)
I had to flash downgrader first because i had CM7r2 hboot originally, and i wouldnt be able to flash stock without downgrading hbooot i think.
Nope, you can flash alpharev Hboots over each other no problem. Only need to flash the downgrader when you want to use the RUU to get S-ON
Did you try my method? did it work? are you S-ON now?
sorry to bump this thread after it's been dead for so long..I have a HTC Desire that I've just unrooted to o2_uk 2.14. I used FastbootCommander v 1.1 to flash HBOOT_Downgrade then I ran the o2_uk ruu but I'm still with AlphaRev Unlock 6.93.9999 s-off HBOOT on PVT1. I tried Bortak's method of downgrading the hboot, I took the rom.zip from the ruu gingerbread 2.3 found in my temp folder, copied it to the desktop then deleted all files other than android-info.txt and copied hboot_8x50_1.02.0001_SF.nb0 to it then copied it to the root of my sdcard as pb99img.zip rebooted but recovery wouldn't flash it....can someone help me please? Even a way of flashing *.nb0 file to the phone.

PB99IMG.zip files are not flashed with recovery, they are flashed using the bootloader. Load into the bootloader (vol down+power) wait for it to search and find the PB99IMG.zip file, press vol up when they say: 'apply update? Vol up to confirm, vol down to cancel' and then press the power button to confirm it.

in the bootloader..that's what I meant, it never asked me if I wanted to apply the update, it just did it's check og pb99diag, pb99img etc but didnt recognise the pb99img as an update file. but nevermind, i've solved it using fastbootcommander v1.5.1..i flashed pb99img_bravo_stock then pb99img_downgrade then the 2.14 o2_uk ruu and i now have back 0.93.0001 happy days!!
I'm also trying to S-On my desire through this method but after flashing downgrade zip from alpharev, my RUU gives hboot version error.. Please help..
same here.... flashed bravo_downgrade to get Alpharev Unlock and hboot version 6.93.9999 ...
this is what I see

RUU
guys, found this thread on my mission to restore ruu, s-on and unroot my device.
guess why? because i'm also s-off after the whole procedure.
i was running CM7r2 with Hboot 6.93.1002 before and then flashed alpharev stock hboot, then alpharev bravo downgrader. i installed the ruu and everything works out fine. i just always stay with s-off, no matter what i try.
tried bortak's solution from this thread too. didn't help.
now that i can't send fastboot commands and have no recovery either i have to keep flashing things via PB99IMG.zip method. i try the downgrader from alpharev and it says "alpharev unlocked". i then install another ruu but afterwards it will stick with s-off.
please help!
thx,
v.
Could try the 2.3 RUU...
phone was not branded, so i need to stick with the WWE versions.

Hence why I said to try the 2.3 RUU, because it's different from the 2.2 ones...
BTW that RUU is the last thing your phone will ever see if it goes wrong, so do it at own risk.
hehe, first you only had "3" written there, so i thought you meant the network provider "3".
ok, so a 2.3 ruu. sure i'll try one, do you have a link?
and why would it be the last one? could i not go back to a 2.2 ruu afterwards?

there is only one. There is a link on my guide.
If the process goes okay, then yes you may, however you need to S-OFF first, then flash the alpharev downgrader, then the 2.2 RUU.
hey bartok,
flashing 2.3 also didn't get rid of my s-off.
how come i can't get s-on? what could be the problem with my phone?
my warranty ends in 2 days and i would really like to send it in for repair. what's causing all the trouble here? everyone just seems to flash the downgrader and then install the ruu. but i'm always stuck with s-off.
please help,
thx,

[Q] Revolutionary hboot - need to return to stock

I've done a lot of reading and see where Alpharev has a hboot downgrader but does this work with CDMA version BravoC?
I rooted using Revolutionary after having hboot 1.06 for a USCC Desire. Phone is out of standard warranty but I need to send phone in for repair under extended warranty. When I flash 2.2 RUU it cannot roll back hboot version.
Thanks!
I still haven't found anything. Thanks for the help.
what was your original Hboot number?
see alpharev page, if your model is supported try this -
flash HBOOT bravo_downgrader and right after that run appropriate RUU wich contains default hboot to protect extended warranty
as a result of this process you become S-ON again with stock Hboot
i think this may work even for CDMA version but i am not 100% sure
google it and you will find the answer
Here is about GSM Desire...
Actually I just use revolutionary to s-off my phone and it work. I test several new ROMs right now, then I try to flash stock ROM back when found this thread. I can flash the RUU HTC Froyo successfully. but...
the hboot is not overwritten. it still revolutionary. I am very sure the stock ROM I use contain hboot. because I can see it upgrade my hboot from 0.8.000 to 0.93.0001 during I flash this ROM before I s-off it yesterday.
revolutionary claim that we can get the original hboot if we flash stock ROM that contain hboot but it not working for me. maybe you need to tell them about this.

[8]STILL S-OFF AFTER RUU
"I want to return my phone for warranty, I used a RUU but I'm still S-OFF"
Cause:
- Alpharev's Hboots are write protected, so that they can not be overwritten by a RUU
HOW TO S-ON
METHOD 1#
[STEP1]- Visit Alpharev and download the "Downgrader"
[STEP2]- Flash the downgrader over fastboot. This can be done with Android Flasher, cmd, or fastboot commander (Note: android flasher is the only program that does not require third party software such as Android SDK or Java JDK)
[STEP3]- You should now notice the title on the bootloader screen is "Alpharev Unlock", run the RUU again and you will have S-ON'd your device.
#METHOD 2#
[STEP1]- Instead of running the RUU again, and putting your phone at risk once more, you can simply upgrade just the bootloader manually, with the PB99IMG.zip method.
[PHASE1]- we need to extract rom.zip from the RUU.
[P1/STEP1]- Run the RUU (BUT DO NOT PLUG IN YOUR PHONE OR CONTINUE), move it to the side as it cannot be minimised.
[P1/STEP2]- go to start menu, and use the "run" feature. Type in %temp%
[P1/STEP3]- select "date modified" to "today" (to make it easier to find). There are should now be 2 folders with long names of random characters.
[P1/STEP4]- search the folders for rom.zip and extract it to the desktop.
[P1/STEP5]- delete everything EXCEPT "hboot_8x50_0.93.0001_20100810.nb0" and "android-info.txt"
[P1/STEP6]- rename the zip to PB99IMG.zip (make sure it is not PB99IMG.zip.zip)
[PHASE2]- now we need to update the bootloader
[P2/STEP1]- put the file in the ROOT of your sd-card (not in any file or folder) and boot into bootloader (poweroff, hold VOLUME DOWN and POWER). After a few seconds, you will be prompted to update bootloader. Select Yes. DO NOT INTERRUPT THE PROCESS, OR YOU WILL BRICK YOUR PHONE.
[P2/STEP2]- Once the process is finished, you will now be S-ON.

[Q] Remove s-off desire (Need to send to service)

Hi,
I am s-off woth cm r2 table using Oxygen.
I flashed the stock hboot table and then the RUU.
The process went perfect and it installed the RUU. But when I start the phone woth Vol dwn + power it still says AlphaRev S-off.
I then tried the new gingerbread RUU and it still the same but the HBOOT is the new one 1.02.0001.
Is there a way of removing S-OFF?
Best regards
Jejja80
Always the same kind of questions here
from http://alpharev.nl/ :
Downgrade protection, these HBOOTs cannot be overwritten by an OTA or RUU, unless you flash a downgrader HBOOT first.

[Q] Downgrade to Stock Hboot

hi
i have installed a Original WWE RUU for my desire which was factory unlocked(sim free)
i was s-off using alpharev cm7r2 hboot image and i changed it to stock apharev, the alpharev splash screen is gone as well as the CWM recovery image but how do i get rid of the hboot?
it is still showing Alpharev at the top as well as a different hboot id which starts from 6......?
this is the RUU i used: RUU_Bravo_HTC_WWE_1.21.405.2_Radio_32.36.00.28U_4.06.00.02_2_release_126984_signed
Thanks in advance
You need to get the downgrader from alpharev then run the ruu again. With the newer hboots you can't change the hboots no matter what you do.
Punched in..

[Q] How to perform official Gingerbread update on a s-off, custom ROM device?

So I have an HTC Desire with Oxygen hboot and devnull 1.1 ROM (AOSP) and I want to perform an official Gingerbread update from HTC.
Bottom line: how do I do that?
Have it downloaded already, but I've heard that trying to install it on an s-off'd device may result with a bricked phone.
go to www.alpharev.nl and download the bravo_stock hboot and flash it..
then download the downgrader and flash that
reboot bootloader
run the 2.3.3 RUU
Actually, I just ran the .exe. Nothing else. I was running on MIUI with s-off and so on, no problems at all
I'll flash the downgrader just in case. Thank you guys

If one can change from S-OFF to S-ON has absolutely NOTHING to with rom, it depends on the hboot one flashed:
If you flashed one the r2 revisions by alpharev (Oxygen r2, CM7 r2; number: 6.93.1002), you have to flash downgrader before you can flash RUU because these newer hboots have an overwrite protection against RUU or OTA.
If you flashed one of the others (N1 Table, Data++, Sense) or the old revisions of Oxygen and CM7 Hboots you don't have to flash downgrader because these hboots don't have the mentionend overwrite protection.
Now I get it all! Thank you
