[Q] Overwriting AlphaRev X Boot with Stock HBOOT

I've successfully set S-OFF for my HTC Wildfire using AlphaRev X Beta after doing these steps:
1- Downgraded HBOOT version from 1.01.0002 to 1.01.0001 (My Arabic based stock HBOOT version didn't work with AlphaRev X)
2- Using AlphaRev X Beta tool to set S-ON to S-OFF
3- Doing backup for ROM and Bootloader
4- Installing ClockWorkMod custom recovery
5- Doing stock ROM Nandroid backup.
6- Installing custom ROM: CM7
For some reason, I'd like to perform a complete stock factory reset, thus, I got the following:
1- Original HTC Wildfire 2.2.4 RUU (Arabic Locale): "RUU_Buzz_Froyo_HTC_ARA_2.37.415.1_Radio_13.55.55.24H_3.35.20.10_release_166943_signed.exe"
2- Extraction of the existing RUU EXE file for rom.zip extraction.
3- Stock HBOOT 1.01.0002: "hboot_7225_1.01.0002_101227.nb0", extracted from stock rom.zip
The Question is: 1- How can I revert back to the original Wildfire for both: Stock ROM, Stock Recovery and Stock HBOOT?
Current HBOOT version: AlphaRev 6.01.1022 HBOOT
This means that installing RUU directly will fail as current HBOOT v. 6.01.1022 is too newer (apparently) than the included 1.01.0002 with the package.
In a question to the AlphaRev X Developer team, I only get one answer to overwrite HBOOT and it was:
Code:
fastboot oem mb 9C068490 1 30
fastboot flash hboot hboot_buzz_7225_1.01.0001.nb0
I'm not sure of those commands at all and I'm afraid doing those to brick my android.
2- I'd like also to know when should I use those fastboot commands?
3- Should I remove clockworkmod to do the fastboot commands?
4- What will happen to the bootloader and the custom ROM after executing those commands?
5- Can anybody explains what does the command fastboot oem mb 9C068490 1 30 mean?
I think all I need is just to overwrite HBOOT with stock one then perform the normal RUU from PC, so I just need help with this point!
I'm very appreciated for your help!

Afaik there's no way to get hboot 1.0 back yet.

Interesting, this probably implies a downgrader wont be needed!
I cant understand by "when" you should. The answer is obviously when you need to get your Stock HBoot! But, I would recommend you remove your Custom ROM and Clockworkmod before you attempt to restore your Stock HBoot. The Stock HBoot doesnt support Custom Recoveries and ROMs, and may lead to issues. Both can be removed by simply flashing any Wildfire RUU, which will restore your Stock ROM, Stock Recovery, but not your Stock HBoot.
Once that is done, follow the 2 commands given to you. But, I would recommend you to extract the HBoot from WWE Froyo 2.22.405.1, since it seems the commands are specifically for that HBoot. Not the 2.37 Arabic one you have extracted. While it should work with the Arabic ROMs HBoot, I wouldnt take chances.
For Fastboot commands, you will need the Fastboot and ADB Binaries for Windows. You can get them here:
http://forum.xda-developers.com/showthread.php?p=14693680
Then, place the nb0 file in the folder where you have placed your Fastboot binary, Open Command Prompt, Browse to it, and execute the commands. The first command obviously is some sort of command which allows "downgrading" of the HBoot.
Disclaimer Note - What all I have written above are from my understanding of your post. HBoot flashing is a very sensitive process, and, I am not responsible if you brick your phone.

Thanks 3xeno for the quick reply. I meant by when was in your reply (Firstly I have to restore stock recovery and stock ROM using the RUU then using fastboot commands).
I understand also that RUU I should use to restore stock recovery and ROM must have the HBOOT.nb0 removed in order not to get any HBOOT error during this process, is that true?
In another way, will the AlphaRev X HBOOT 6.01.1022 with S-OFF allow running stock recovery and stock ROM without needing to overwrite the HBOOT (some would prefer to overwrite to stock HBOOT for warranty stuff... etc)?
And my original stock ROM was Arabic based one, so the commands above won't work with me? (Note that second line will be hboot_7225_1.01.0002_101227.nb0 as from my information that HBOOT 1.01.0002 supports locale options.
Thanks!

First restore the stock things and then use those fastboot commands. You can also restore stock things (except hboot) from fastboot flashing or pc49img process.

I think some people even used ruu without removing hboot.nb0 (just for rooting after alpharevx). But I haven't done it (not willing to get back to stock). For me alpharevx s-off and cm7 are more than enough. And you can also remove nb0 file from rom.zip and use the rom.zip with pc49img process to get back to stock things except hboot.

You need to really have clarification before doing this. Better contact the team again.
You have got 2 fastboot commands right. I think the 1st command may be specific to hboot 1.01.0001. . This needs to be clear. And also confirm whether it can be flashed on wildfire with previous Arabic based stock rom. I think better to use WWE stock rom to restore stock recovery and os. Then using hboot 1.01.0001.nb0 from wwe ruu.
NOTE : I'm not responsible for any brick of your phone. I just tried to make things clear.

- No, it is not necessary to remove the HBoot file from an RUU before flashing it. You can normally flash an RUU on your AlphaRev S-OFF'ed Wildfire. It will not touch the HBoot, but, it will remove your Custom Recovery and Custom ROM.
- Yes, AlphaRev will allow you to run with Stock recovery and Stock ROM. This is exactly what happens immediately after you complete running AlphaRev X. Your phone has a new HBoot, but the Recovery and ROM are untouched. (Which is why you have to follow additional procedures to get Custom Recoveries and ROMs)
- The above commands *should* work for you, provided you replace the values with the appropriate one, but, I am not too confident in you doing that because AlphaRev didn't support all versions of HBoot 1.01.0002, and, I think the Arabic official ROM was among them. Which is why I am suggesting you follow the above commands with the WWE 2.22.405.1 HBoot. In any case, after that, you will have a Stock Recovery, ROM, and HBoot, and you can again run the Arabic RUU as normal, and get back your phone in your stock condition, with the Arabic locales, and on version 2.37

Last Question
Thanks everyone for the quick and effective answers, I decided to perform an installation of stock RUU (Recovery and ROM) with AlphaRev X HBOOT 6.01.1022 without needing to overwriting HBOOT version (except if I need to get help from HTC Support - warranty purposes ).
Yes, the first step after setting S-OFF is that I get a stock ROM and recovery before trying to get custom recoveries and ROMs, but what I have used was WWE ROM which was included in the guide
Last question is: After installing stock ROM and Recovery over patched S-OFF HBOOT 6.01.1022, is it possible to overwrite it with stock HBOOT 1.01.0002 in the future using fastboot commands, or it won't go through because stock ROM/recovery are not rooted?
Thank you!

It should go through, because Fastboot is a function enabled by the Bootloader (HBoot). The Recovery / Root has got nothing to do with it.

Nvm...
Presently Fastboot flashing on wildfire is a feature of alpharevx hboot s-off only. It should be there as long as alpharev hboot is there.

it works!!!! my gosh! back to original h boot 1.01 WWE FROYO extracted

Is S-ON comes back? If not, it still will not have warranty.

Yes. S-on is back.

Well if overwriting hboot with fastboot is possible. then why not overwrite it with
HBoot 0.08.0008 so if you want, one can use Unrevoked to gain s-off in the future no matter what version of Rom you are using. (possible)???
As long as you have alpharevX s-off to start with..

I will try... later

You have to extract the ROM.zip from the RUU's EXE file. Anyway, I have attached it from the WWE 2.22.405.1 RUU. Remember to unzip/rename before use.

Well I need ruu for europe cuz im theere. And yes,I can get into hboot. From there I tryed recovery.

I'm from europe too and the right ruu for mine phone is the RUU_Bravo_Froyo_HTC_WWE_2.29.405.5_Radio_32.49.00. 32U_5.11.05.27
And i think you have to use that one because of the hboot. the ruu you are using have a old hboot version and i dont think the ruu will downgrade hboot..
But if you can enter fasboot use that to flash a recovery and wipe youre phone then install a custome room on it.

Before installing RUU, make sura that you have installed Alpharev stock hboot
1. download from alpharev.nl the file "bravo_alphaspl.img" then put it on your desire with fastboot
2. install RUU
I did that 5 minutes ago..

Use the attached file.
Put it in the root of your card (not in any folder)
Reboot by pressing Vol- and Power button.
When asked to update, confirm with Vol -
This should give you a working recovery. Then you can flash any rom as you usually do, and at that instance, your bootloops will be solved too.
After this, if you still wish to return Hboot to Stock (without losing S-Off), you can use this PB99IMG. <Make sure you rename it to the same name as the previous file after deleting the former.

[Q]How to flash Radio and HBOOT

Hello. I want to make sure that the method I read about of flashing the Radio is correct, since this could permanently brick my device.
I have ROOT and S-OFF but nu custom hboot yet. My partitions are stock.
I. To flash a RADIO:
1. Go into recovery
2. Choose install zip from sd
3. Choose zip from sd
4. Confirm
5. Reboot
II. If later I want to flash a custom HBOOT:
1. Download the HBOOT I want (and rename it to PB99IMG.zip)
2. Put it on root of SD card
3. Boot into bootloader (Volume Down + Power)
4. It will ask If I want to upgrade the HBOOT - Select Yes
5. It will reboot on it's own ???
6. Install ROM
Check MD5 of Radio and ROM.
Also I'm unable to check the MD5 of the zip file I've downloaded from AlphaRev - PB99IMG.zip, because it doesn't match. Is this ok?
Are these steps correct?
If there are also other way's I'm more than gladly to know.
I know about AndroidFlasher, but I don't want to risk upgrading from PC, cause lately there were some power down's of the electricity I don't want to risk to happen when I'm in the middle of flashing something as important as Radio or HBOOT.
Thank you for all your help.
L.E.: When do I need to flash the HBOOT downgrader? When I want to go from one HBOOT to another do I always have to first flash the downgrader and then the HBOOT, or there are only certain HBOOT's that I have to apply this prior to installing another HBOOT?

To check the md5sum you have to extract the hboot.img from the downloaded pm99img.zip file and compare its to the one you can find on the homepage.
Nevetheless, I highly recommend to flash new hboot with fastboot, because the method with the pb99img.zip does not work very often.
Download the image you want, for example the cm7 r2 hboot (bravo_alphaspl-cm7r2.img). Store it anywere you want, I recommend a place where you can go very easily, maybe partition C.
Check the md5sum!!!!
Boot your phone into fastboot mode (start it with pressed back and power button). Now start cmd in windows, connect phone to computer and type:
Code:
fastboot devices
The output should be:
Code:
List of devices attached
HTxxxxxxxxxxxxx device
Instead of xxxxxxxx you should see the serial number of your phone. If it's so, enter the following comments:
Code:
fastboot flash hboot c:\bravo_alphaspl-cm7r2.img
fastboot reboot-bootloader
fastboot erase cache
Now you have new hboot (in this example cm7r2.) In the first line of your bootloader you should see "AlphaRev Cm7r2".

Thank you. I'll save this text for further uses. So this is the best way to flash another HBOOT.
The method to flash the radios is good?
Thanks.

personally I find it A LOT easier and quicker to use fastboot tools such as fastboot commander. I think it's also better for novice users, and it gives you functions that novice users may not know when it comes to using fastboot with cmd.

Alpharev uploaded r2 of the hboots for cm7 and oxygen. These two hboots have a protection, that they cannot be overwritten. So if you are using one of these hboots, you have to flash hboot downgrader before you can flash a new hboot.

I have read this thread before I ROOT-ed my phone. It would probably be more easy to flash either Radio or HBOOT through fastboot, but since I've got the problem I mentioned about in first post, I don't want to take the risk. What if the power goes down when I'm in the middle of flashing...then there goes down the phone too
I'll try the fastboot command when I can use my GF's laptop.

Thank you very much.
So to use the HBOOT Downgrader I have to have first one of the two (either Bravo Oxygen r2 or Bravo CM7 r2), and then if I want to put another HBOOT: Flash HBOOT Downgrader ---> Flash HBOOT Bravo Stock ---> Flash Other HBOOT.
Ok. Now I got it al sorted out.
Thanks for all the help.

The step with stock hboot is not needed. You can flash downgrader and then directly the new hboot. The downgrader deletes all partitions.

you only need to flash the HBOOT downgrader from alpharev when you are using a RUU to unroot your phone. Aplharev's HBOOT's are designed so that a RUU will not overwrite the HBOOT - untill you downgrade it using the downgrade utility.

The step with stock hboot is not needed. You can flash downgrader and then directly the new hboot. The downgrader deletes all partitions.

THX a billion!
Im on cm7r2 and want to reverse to stock.
Was looking for exactly this answer!
I to read somewhere that someone just flashes the hboots that he wants,
but not talking about downgrader-use (couldnt find it again - so searched for something like this answer!). And Alpharev dont say anything about
using the downgrader only this:
"Downgrade protection, these HBOOTs cannot be overwritten by an OTA or RUU, unless you flash a downgrader HBOOT first."
So downgrader is only nesccesary if wanting to go stock with a RUU or U want to get OTA.
So, UsManyDead... whatever hboot U use, just flash the next hboot U want.
(remember backup and all that sht. )

Alpharev uploaded r2 of the hboots for cm7 and oxygen. These two hboots have a protection, that they cannot be overwritten. So if you are using one of these hboots, you have to flash hboot downgrader before you can flash a new hboot.

Before flash: Alpharev cm7 r2
After flash: Alpharev

Thanks a lot man. It's finally sorted out.

[Q] Simple? Hboot problem

Flashed the stock hboot on the alpharev site.
Wanted to flash a data++ rom so downloaded the oxygen hboot, md5-ed compared, and flashed.
Appararently from what my bootloader says my hboot cannot be downgraded now.
So my question:
In order to flash the oxygen hboot, do I need to flash the bravo downgrader available on the alpharev site prior to flashing the oxygen hboot?
Many thanks in advance.

Well I Changed mine from Cm7r2 to Oxygenr2 without the downgrader a few weeks back.
But i'd give a try flashing the downgrader first, then the oxygen Hboot.
If you want to flash the older oxygen HBOOT (not the current on Alpharev's site - that's Oxygen_r2) then you definitely need the downgrader.

i dont know how you exactly flash it, i personaly reccomend android flasher 1.8
you need to enter fastboot and start AF program, then you choose to flash hboot and thats it,
you dont need to flash downgrader in case you wanna change your current hboot
downgrader need to be flashed when you want to return S.ON before executing official RUU for example froyo RUU 2.29.405

I thought the easiest way how to flash hboot is via adb. I did it many times without any problem

yeah, 100 people 100 solutions
for me the best and easiest way is via android flasher, never try via adb so i cannot compare

Yea I used ADB to flash. and it shows on the command prompt that "UPDATE BYPASSED" and the bootloader that the hboot cannot be downgraded. and hence the question.
Thanks for the feedback everyone =) Would try the downgrader method a day or what from now and post the results back.

Personally I use fastboot to flash everything.. that's how I learnt and that's the way I'll stick too
you can use either command prompt or fastboot commander (I'd recommend, lots of good features and has never failed) or android flasher (never used before but hear good things)

Here's what I did:
1)fastboot flashed downgrader hboot
2)reboot bootloader
3)sucessful flashed oxygen r1 hboot without update bypassed showing
4)profiting from data++ now =)
thanks all for the feedback again. really appreciate it. =)
problem solved.

HTC Desire -- can't go to Hboot

Hello! I have the strangest problem, and wondered if someone could help.
I received a present from a friend, a second-hand HTC Desire GSM, but it didn't have stock Android and was running on a custom ROM installed on the SDCard. I wanted to install CyanogenMod on the phone itself (not the SD Card) and tried to with the phone by reading up details online. This is my first time with an Android phone, and I'm not sure what I did, but now I'm unable to boot into Hboot recovery.
I think the problem began when I installed the file "RUU_Bravo_HTC_Europe_1.15.405.3_Radio_32.30.00.28U_4.05.00.11_release_121865" from a certain website, and ever since I can't seem to flash the phone with another RUU. Can someone please help me make the phone usable again? I'll post the details below based on what I could find as of recent:
AlphaRev Oxygen r2
Bravo PVT1 SHIP S-OFF
HBOOT-6.93.1882
M1CROP-831D
TOUCH PANEL-SYNT0101
RADIO-5.11.05.27

You are SOFF.
Follow these steps in sequence
1. Get the stock hboot from alpharev.nl and flash it from fastboot
2. Get the 2.3 RUU from htcdev and run it from PC with phone connected with USB
3. Flash the 4ext recovery from fastboot.
4. Flash any custom rooted rom from recovery

Please stop telling people to flash stock hboot over every other custom hboot, cause most of the time thet will succed but eventualy someone will end up with hboot brick. It is recommended to flash downgrade hboot prior flashing any other.
In his case he doesn't need to run RUU, he is s-off so all he needs is a different hboot (oxygen has a lack of space on system partition), 4ext img from Jmcclue's thread that can both be flashed via fastboot and then a personal choice of rom.

I dont recall telling people to flash stock hboot before this. I had noticed that he has got a oxygen r2 hboot. It is perfectly safe to flash the alpharev stock hboot over this. I would only use the downgrader to remove write protection from my hboot so that when I run the RUU I get SON.
The OP also stated that he is not sure what he has done so I would run the 2.3 RUU just so that he can work from known territory.

hes S-OFF with no recovery and has CM rom on sdcard soo like nloooo says flash recovery and then he can flash the rom on sdcard after a full wipe (if it fits on Oxygen r2 hboot) or change hboots and flash new rom if he wants
