[Q] I understand everything except the point of the eng hboot. - G2 and Desire Z Q&A, Help & Troubleshooting

From my current understanding if I wish to flash individual pieces of a ROM such as a new radio or stock recovery (for warranty purposes) I need the eng hboot for fastboot? And returning to the original hboot is as simple as flashing a stock RUU, after setting superCID and permanent S-Off with gfree of course?

[Q] Can I use any RUU for any DHD?

What does the RUU replace exactly?
Can I brick my phone by flashing the wrong RUU?
Why do people downgrade instead of flashing an older RUU?
The RUU replaces everything. Radio, bootloader, ROM, recovery. So you'll loose root and ENG S-OFF but you'll keep radio S-OFF.
You cant flash an older RUU if you don't have S-OFF.
And no, it doesn't matter which RUU you flash.

is the radio S-OFF flag hidden that deep? even an RUU wont reset it!
so basically if I have radio S-OFF I can flash any RUU I like. that's cool
btw what's ENG again? and what's the different between ENG S-OFF (or ON) and radio S-OFF (or ON)?
my understanding is that if you have radio S-OFF then everything is S-OFF and you can mess with the device as bad as you like
the way i understand, you could say Eng S-OFF is a "security off" placed after bootloader and Radio S-OFF is a "security off" placed before it, so even a normal bootloader see it as a S-OFF... please, someone correct me if i'm wrong.
Radio S-OFF isn't THAT deep, it's just stay in a place not touched by flashing officlal RUU.
So when you are Radio S-OFF and flash a RUU, bootloader and everything beyond it is replaced; you keep with a Radio S-OFF (cause it stays before bootloader), but lose Eng and Root (cause it stays after bootloader).
you can't flash a older RUU without Radio S-OFF and to achieve it, you need eng s-off and for that you need root. So, if you have a 1.7xxxxxx RUU, you can't simple flash a older RUU...
i hope it could be understood, my english is not quite good when i need so much adverbs, past sentences and whatever more! =o)

Unrooting

Hi!
My phone broke and now I want to try to get it fixed with warranty. I'm not sure if warranty still is available if I use root so I want to unroot.
I have read that all I need to do is flash the RUU, but which one? http://forum.xda-developers.com/showthread.php?t=824357
And what will flashing it do? Will it remove CWM and everything else I was using to root? I remember that I flashed radio 2 times, had S-OFF and E-ON.
And then I will simply run System Update? Because it seems that RUU are firmwares that phones are shipped with.
yea, just flash a RUU.
Make sure you install the original RUU for the type of your DHD (i.e. WWE, Voda,T-Mobile...)
and if your phone is S-OFF, make it S-ON - S-OFF / S-ON GUIDE (guide for S-ON is at the end of the 1st post). Go into bootloader and make sure you have S-ON
--your recovery will be restored to original HTC recovery
Oh, but which RUU I need to flash? I remember I needed to do a downgrade and I think it was 1.72.405.3, not the R2, but I'm not sure.
Well, when you had your phone, was it branded?
if so, you need to find a brand-specific RUU.
If not, then WWE RUU is fine.
i would suggest the 1.32 FW (because S-ON requires temproot from Visionary+), then follow the guide to S-ON
What about radio? I have flashed the leaked gingerbread radio, wouldn't they be able to see that I have flashed a newer radio? Or the RUU flashes radio also?
RUU flashes radio too. But after flashing the RUU have a look into the bootloader, the device might still be S-Off. For S-On you need to root again and Use the easy radio tool to make S-On again. Then use the RUU again.
It still was S-OFF, but used Visionary and Easy Radio Tool to get S-ON. A brand new phone
Thanks!
Does it work the RUU to flash even if I come from an ext4 ROM (ARHD 5.1.9)?
Or do I need to format first by cwm 3.0.2.6 so that it is ext3 again?
No one any advice?

[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.

What is it for? My buzz is ukrainian so is it right for me ? Sorry for my english
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.

Yes! S-ON is back very successfully! I've got my phone as if I got it from HTC distributor! I'll post a full thread for a step by step guide to S-OFF then S-ON back ASAP!
I`ve done it. The H-Boot is 1.01.0001 and ii is also s-off. Interesting

Making phone stock - need warranty

Hello, I have rooted my buzz but now i need warranty and i have to downgrade hboot to 1.01 (stock) and ruu to stock, i have found ruu at shipped roms but need hboot with s-on and stock rom with shipped t9 apps and all of this because of warranty. Is this any way to do that?
Did you get S-OFF using an XTC Clip or was it using Revolutionary? If it was using an XTC Clip, there's no way to get back S-ON as far as I know, and, if it was using Revolutionary, then, you will need to extract the HBoot File from the RUU (It's a .nb0 file), and then follow this guide to get back to HBoot 1.01.0001 S-ON:
http://forum.xda-developers.com/showthread.php?t=1160251
Apart from this, flashing an RUU will recover the stock ROM completely, including the Stock apps.
I was using revolutionary and i have also backup of original android from stock with boot.img recovery etc. i'll try that way that You gived
In that case, you can also use Fastboot to recover your original boot, recovery, data, system etc, and then follow that guide to get back a S-ON HBoot. In that way, you need not flash an RUU.

[Q] S-off

Do i need to S-off my device, before I install any customer ROM or I can go ahead with the s-on ?
Hi,
You don't need s-off to flash custom ROMs. However with s-on you can only flash ROMs made for stock hboot. In order to flash ROMs for other hboot, you need to be s-off, so you can flash different hboots.
Personally I'd s-off my desire. The choice is yours.
