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.

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.

While installing the ROM it gives an error relating to the the bootloader version. Do I need another RUU, if so which one? This is the only Vodaphone UK RUU I can find. If not do I need to upgrade Bootloader or downgrade it. (How?)
HELP!

First, tell us which type of hboot you are using (cm7r2, stock...).

Bootloaders cannot be downgraded.
Are you using one of alpharev's r2 hboots (cm7 or oxygen)? If yes, you have to flash bravo downgrade first, because these both new hboots are locked. This means they cannot be overwritten. After you have flashed bravo downgrade, try to flash ruu again.

How do I check which bootloader I have? and what do you mean by Bravo downgrade?
All I can see in fastboot is "hboot 0.93.0001" It doesnt say wether its Alpharev or stock?
Sent from my HTC Desire using Tapatalk

Boot into bootloader and check first line. What's written there?
I mean if you have one of my named bootloaders, you have to download bravo_downgrade.img from here:
http://alpharev.nl
After flashing this via fastboot you should be able to flash ruu successfully.

What do you mean by flashing through fasboot. I know how to apply .zip updates from recovery but how do you do it through fastboot? Does it need to be connected to a PC, any pre requisites for this method? I can see their are steps mentioned on the link you posted but I don't understand step 3. If you can clarify I will be very thankful.
When I boot into hbbot and there are options like "fastboot" and recovery etc. On the first line it says HTC Bravo PVT1 SHIP S-ON ?

Ohh I sort of get it now. The custom bootloader thingy can only be installed with S-OFF and I can only downgrade the bootloader with S-off which I don't have. So now I trying the RUU you mentioned. There are there vodaphone RUU's on the site. After trying all three, if they don't work, I have to S-off the device THEN run the Bravo downgrader and then flash any one of the three RUU's again, right?
Thanks for all the help man

Not so fast. Try to flash the latest ruu I posted. If this doesn't work, we will see further.

Mine worked because you wanted to flash an ruu which was too old for your phone.
The number "2.33.161.2" is referred to the software number of android or rather in this case of the android software number with vodafone branding.
32.49.00.32U_5.11.05.27 is the radio.
1) You can use fastboot, flash different partition layouts or you can delete apps from /system/app while phone is running.
2) More space for your desire.
3) You can install custom roms, backup your apps and system with e.g. titanium backup or you can "take a picture" of your current system configuration with nandroid backup.
For more information, just use the search.
And do not forget to hit the thanks button.

Thanks. You are AWESOME.
Edit:
I forgot. I dropped my Desire a few weeks ago and the screen got cracked. I got the front glass replaced but now the proximity sensor stays ON all the time. SO when I make a call, the screen goes black and the ONLY way of getting the cell back in is removing the battery. I'll get the cell phone repaired in a week or two. Till then is there any app or any way I can disable the proximity sensor? I was using an MIUI rom before I flashed the RUU and it had an option under "Call settings" to turn off proximity sensor so I'm sure it can be done. Is there any other way to do this without having to go back to MIUI? :|

[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.

OP. You need to first S-OFF with revolutionary. Then flash the downgrader from alpharev. Then flash either a RUU for your network provider, or the WWE RUU (however you need a goldcard if you want to use the WWE RUU as it de-brands your phone).
If you need help on how to use revolutionary, or flash the downgrader then look at my guide.
