1. Download the Zip file http://d-h.st/tRa
2. unzip it and place the PG6IMG.zip on youe sd card reboot into fastboot
( here it will flash the .zip and change the boot loader from current to 1.08.0099 once it is done it should say unlocked)
3. reboot and remove the .zip from sd card.
4. run the .exe file (this will flash CWM)
5. place the root.zip onto your sd card
6. reboot into recovery or got to fast boot then recovery
7. go to install zip from sd card scroll down to the root.zip file select it and say yes. now let the update work.

M phone identity is HTC Wildfire s A510e and i saw that it is S-ON in the bootloader. Is the procedure applies to my mobile ? or i need to make it s-off as i have seen in many guides. If so how to do that and what is s-on and s-off.
then at step 4 you specified that running the .exe file will flash cwm. what is that cwm ? please reply asap.
CWM is a custom recovery. If this method is not working try simonsimon34's method. I tryed every other method out there and this is the only one that would work.
Try his method if it dosent work then we will go from there. Also this method on unlocks the bootloader it does not make s-off

Any chance to do that? I`m stuck in custom rom and no chance to flash any of stock ROM`s because of hoot version... Same thing with fastboot.. No chance to flash hoot .nb0 from fast boot.. Thanks in advance
Have you tried using revolutionary?
Or the HTCdev Unlock Tool?
Yes, revolutionary does not support this version of hoot...
And boot loader is unlocked by htcdev site, but that is a problem now for me..
Do you have clockworkmod recovery?
Yes, CWM flashed from fastboot? Is there a way to flash hboot from CWM or..?
What happens when you try flashing a rom from CWM or wiping?
Signature error if i try rom with hboot.img in .zip... I only could flash a rom without hboot.. But my aim is to downgrade hboot...
You can't just flash any .zip file randomly. Especially if it's something as sensitive as the bootloader.
And try flashing a rom in CWM, you might not need to downgrade.
Naturally, I understand that and I understand well how should i have flash.. When i wrote zip rom without hboot i meant Buzz_Froyo_hTC_WWE_2.22.405.1_SAFE_FLASH_ZIP...
I want to downgrade hboot version to be able to use revolutionary instead of htcdev unlocked boot loader, understand me? Mentioned Froyo ROM does`t have hboot image in archive, and that`s why is safe...
I'm not sure if the HTCDev bootloader can even be unlocked.
But don't take my word for it...
I just hope you're wrong.. I hope that team mate from revolutionary have some idea in the future days...
Actualy, after looking at the RUU you were trying to flash. It's "safe". You could try using a "non-safe" one.

Are you trying to flash an ruu Rom.zip from recovery?
Sent from my HTC Wildfire using xda premium
@nejc121
Give me the link of "non-safe" to try?
@Scratch0805
Yes, i tried just that, but with no luck...
It can't be done like that, I think the images need unpacking first, if you look inside a custom Rom and compare it to your Rom.zip you'll see the difference.
I don't think you can use PC49IMG after unlocking with HTC dev either so your only option is fastboot and after I read the warning about not going back after using the tool it wouldn't surprise me if they locked it so it can't be flashed with fastboot either.
Sent from my HTC Wildfire using xda premium
Every section of Stock ROM i could flash with fastboot, except hboot which is my highest goal... You are right, i can`t use PC49IMG.zip anymore...

Hi guys,
first of all... forgive my english.
Please help me to get S-OFF on my buzz with hboot 1.02.0000 UNLOCKED (Unlocked by HTC DEV SITE guide)
I've got CWM on my wildfire, and used gingerbreak to get superuser privileges, but CWM recovery mode doesen't work anyway, when i try to boot my buzz in CWM Recovery Mode, appears a RED Triangle with an "!" and I can't do anything but if i press Vol UP and Power Button, appears a menu with:
- reboot
- update with update.zip
- wipe cache
- wipe data factory/cache
I've tried all of these options, but it doesen't work.
I've tried with revolutionary, but it doesen't work, when i start the .exe file, it says
"buzz, with hboot 1.02.0000 is not supported at this time"
I think my issue is because of I didn't get S-OFF on Hboot 1.02.0000 .
please help me to flash the ROM 've chosen to use.

when the bootloader is unlocked using the HTCdev method ,there is no s-off required.. BTW try flashing the cwm recovery again using the fastboot method becoz the options you mentioned seem incomplete..maybe after doing this you may get "install zip from sd" option in cwm recovery so that you can flash custom roms..
Alternative: You can rename the custom rom to update.zip and put directly on sd (not in any folder) and choose "update with update.zip" option which you already have in cwm recovery.

Hi,
I've spent the whole day trying to install a new ROM on my wildfire s.
I'm able to unlock (and relock) the phone, and was using this post as a guide to install the new rom :
http://forum.xda-developers.com/showthread.php?t=1633198
I've put the zip file on the SD card, and in hboot, it's scans for PG76IMG.zip. It checks and parses PG76IMG.zip. But then there is only the usual
options. When I select recovery, I get a black screen with red triagle and exclamation mark.
I've also tried upgrading the ROM with the HTC RUU, described in the HTC website to unlock the phone (step 1).
But my phone doesn't accept the EU ROM. (I need to upgrade the software over wifi first using 'check now'). But there's no update available.
Tried several guides but none worked. Can anybody help?
some details :
- android 2.3.5 (htc 2.1, softwarenr 2.26.401.3)
- unlocked
- hboot 1.09.0099
Thanks!
Thomas.

There's a easy method,just download cwm recovery.img for wfs...
Plug ur wfs with pc
Switch off ur wfs and open fastboot in bootloader mode.
Open command on ur pc and type:
fastboot flash recovery recovery.img
This would install cwm recovery on ur wfs and then u can flash roms .

Hi dudes
Recently I unlocked my DHD with HTCDev method and flashed JellyTime ROM.
Now, I want to perform a sim-unlock but I don't know if i have to reinstall my stock rom...
Is there an easy way to achieve it?
This is my system configuration:
HBOT-2.00.0029
RADIO -26.14.04.28_M
carrier: Vodafone ES
Thx in advance
U will need to make a goldcard to sim unlock ur phone or debrand it. Use the advance ace hack kit (AAHK) from ATTN to sim unlock ur phone make sure u read the effron manual provided with it. Search for ACE think tank in the development section I m sure it will help.
Sent from my HTC Desire HD using xda premium
Finally I called to my carrier to obtain the sim unlock key. It's not necessary to go back stock rom.. I tested with another carrier sim and ask me to enter the unlock key.
Thx for your answer.

If you get the unlock code there is no need to use any tool. Bootloader does not need to be relocked as it has nothing to do. You will only need a sim from a different company in order to get the network prompt.

i placed custom rooted file which was mention to put into root of sd card,i did that then ran HBOOT it showed me parcing [PD98IMG.zip] and goes it automatically don't know what to do next!?
Then i placed PD98IMG-1 file into subfolder of PD98IMG and run that aahk2.cmd but it still says no such file found. did format sd card twice. things that one sd card is from kingston and another one unnamed,in both it showed me PROBLEM PROBLEM PROBLEM!
1) either memory card not mounted
2) you sure charge cable is in chargemode? or data sync mode? check it?

the AAHK2 script will make your phone to process downgrade first then re run a second script for full s-off..and before you do it all that..you must have a branded sd card that already mentioned in the thread..
step :
1. if you had sense rom then you must set disable of Fast boot first from settings> power
2. you must enable USB Debugging on your phone under settings>development>usb debugging (check it)
3. you must installing latest HTC driver..you find it here..
4. you must install SDK or ADT to support adb & fastboot command..you can download from here..
5. if SDK or ADT already setup..you can connect your phone (just charge mode)..then open cmd from your pc..then change source directory to Platforms tools directory..sample if you place the SDK or ADT folder under "C:\" drive..then the command might be "cd C:\adt-bundle-windows-x86_64-20131030\sdk\platform-tools"
6. test adb connected.. type "adb devices", if adb success detected your phone then there will be prompt with serial number of your phone at list of attached device
7. if adb success detected your phone..then you can continued to type "adb reboot bootloader" that will bring your phone rebooted into bootloader..
8. in your phone bootloader you must choice FASTBOOT..then type in "fastboot get-var all" this will show your info about the CIDnum of your phone..(check it In the line "INFOcidnum ......." , copy that to notepad before closing a cmd..
9. find the right RUU required by AAHK that matching with your CIDnum for downgrade process..you can find it here..and place it in PD98IMG sub folder from AAHK2 folder
10. disable your antivirus..then running AAHK2 script as administrator..then follow instruction for downgrade process first..then continued running the second time AAHK2 script for full s-off process..
11. flashing RUU that already rooted and modified by Phiber2000 to fix gps..
12. DONE
note : if you had prompt "PROBLEM PROBLEM PROBLEM" while running AAHK2 script..then might be problem under USB debugging on your phone..try disconnect usb then disabled it first and enabled it again..then try connecting again with your pc
hope this can help..sorry for my bad grammar

Of course. Just flash recovery using command fastboot flash recovery recovery.img and u are ready to flash rom. The example of recovery.img is cwm recovery which u can download it from their website. As you are s-on, u need to flash boot.img contained in the zip files of the rom that u flashed everytime u flash a new rom. The command is fastboot flash boot boot.img. When u are writing the command, make sure ur device is connected in fastboot mode.

No need for doing S-OFF since this version of bootloader can be unlocked without it. If you really need it for something, the only solution I've seen so far is using XTC Clip device, google it.
First backup everything you'll need later using some backup app, unlocking will require factory reset.
Go to HTC dev and unlock your bootloader, a bit lengthy procedure, but not so hard, just follow the instructions on site.
http://htcdev.com/bootloader/
After your bootloader is unlocked, get Clockworkmod recovery for your phone from
http://www.clockworkmod.com/rommanager
Use fastboot command you have used in unlocking phase to flash recovery. Phone should be connected via USB, in hboot mode, fastboot option chosen, drivers installed on PC, but you should learn all those details during unlocking phase. Command should look like:
Code:
fastboot flash recovery recovery-clockwork-5.0.2.8-marvel.img
Now you can enter Clockworkmod recovery by entering HBOOT and selecting recovery option. Get familiar with it
Now,
1) If you just wish to root your phone, nothing else, use CWM recovery to install this zip
Code:
http://forum.xda-developers.com/attachment.php?attachmentid=672519&d=1312136127
It will add Root access app to your phone.
2) Since you worked hard, you deserve better than this. Install newer and more awesome ROMs using CWM recovery
I've tried Cyanogenmod 7,9 and 10, few MIUI versions, WildChild 3.3, and one AOKP version so far, using Oliver96's CM 10 ALPHA2 build at the moment, needed a lot of effort (SD partitioning, installing custom Google Apps, various tricks to get more space on /system, etc), but now I have Android 4.1 and everything works as charm

You need to download the Clockworkmod Recovery img file from your WFS internet browser, then you also need to download the root script, after that you just need to disable fastboot from Settings>>Energy (Or battery)>>Tick Fastboot
BE SURE YOU HAVE CWM RECOVERY IMG (PG76IMG.zip) ON THE ROOT OF YOUR SD CARD AS WELL AS THE ROOT SCRIPT (Root.zip).
Shut down your phone, take out the battery and put it back again and press the VOLUME DOWN + POWER keys, it should boot to HBOOT, after that wait a bit and it should tell you if you want to flash that PG76IMG.zip
After that just scroll to RECOVERY to boot CWM recovery.
Then select Install zip from SD CARD, choose zip from sd card and select the root.zip file you just downloaded.
After that go back and reboot your phone and there you have it, your WFS is rooted.
EDIT: Not sure If I can post this or not but this guide helped me root my WFS and it was successfull.

Uhm... I rooted my phone S-ON and unlocked the bootloader through HTCDev so yes it does work.
You have misunderstood me, you can root and unlock without issue. But once you htcdev unlock the bootloader will no longer flash updates like hboot-recovery-system ect via the pg76img.zip method as it cannot guarantee that they are from HTC. This is why you must relock the bootloader before running a ruu.
