[Q] EVO 4G: Need to install stock Bootloader - EVO 4G Q&A, Help & Troubleshooting

Hello XDA,
I have been trying to unroot my phone, but have been running into a problem. I was able to restore my backup of the official Sprint ROM I took after using to Revolutionary tool. But I cannot figure out how to install a stock bootloader.
I tried using the files at; http://forum.xda-developers.com/showthread.php?t=801568 but when I load up the gootloader and press volume up to have it install the bootloader, it says "[1] Bootloader - bypassed" and asks me if I would like to restart.
Any help would be greatly appreciated.
My phones info;
HBOOT 6.16.1002
Radio 1.36.00.04.02
Security S-OFF
Android 2.3.3
Baseband 1.36.00.04.02
Kernel 2.6.35.10-gc0a661b

To the best of my knowledge it can't be unrooted yet.

According to this site, all hboot versions after 0.97 are not downgradeable, however, since you have the 'international' hboot version, I'm not sure if it applies, but I am 'assuming' it does.

[Q] (Q) What method do I need to use to root?

Android Version 2.2
Baseband Version 2.15.00
Kernal Version 2.6.32.15-ge2f608
Build number 3.29.651.5
Software number 3.29.651.5
PRI version 1.77_003
Hardware version 0002
HBoot 0.97
Radio 2.15.00
Tried rooting with unrevoked 3.21. At the end of the process is says "Failed to flash recovery image." Recovery image clockwordMod Recovery.
I had rooted previously and then updated and lost root. I still have superuser permission app.
Any help would be greatly appreciated. I have gone through many of the previous threads, but have not been able to figure out why the unrevoked method would not work for me considering my HBoot is not 2.02.
Thanks!!!

when you boot into bootloader, do you have s-on or s-off?
s-on

I do not have a custom recovery. can I still use unrevoked forever?

Maybe try downloading and running an official 3.29.651.5 RUU and then try unrevoked3 again to root.
yes if you do not have a custom recovery download a RUU from this link...http://shipped-roms.com/index.php?category=android&model=Supersonic
after downloading the ruu...plug your phone in and run it and then it will revert your phone back to stock...then you can try agian to root
good luck
My phone is running stock. I have never flashed a ROM. I had used unrevoked previously. I did not save any of the settings. When I updated, I lost root. My HBoot is 0.97, so I am unsure why unrevoked will not work for me. I do not have the ability to change ROMs or for a custom recovery. I do not have ClockworkMod recovery. So I do not think I can use unrevoked forever, or use any other ROMs.

Proper steps to updating HBOOT, radio, S-off, etc from stock 2.2 to prevent BRICK?

So long story short I've done all these to MY incredible several months ago starting at 2.1. I now run latest hboot, radio, s-off, blah blah with CM7. My friend has a stock 2.2 dInc and wants to do the same.
In what order should these be upgraded/installed to go from a stock 2.2 to CM7? I remember when I was upgrading all my files there were certain no-no's that would brick. I'd really like to prevent that.
Right now I'm thinking for his stock 2.2:
Root 2.2
Update HBOOT to .92
Update radio to latest (2.15?)
Perform S-off
Install CM7 rom
Will that work?
When you root it can run the s-off patch for you at the same time. Other than that everything else is fine, no worries.

The newest version of Unrevoked3 installed Hboot .92 and did the S-off for me as well.

[Q] How to UNROOT EVO 4G UNREVOKED without usb??

I used revoked3 to root my evo
hboot 0.97.0000
radio 2.15.00.09.01
build# 3.29.651.5
Used metrodroid rom
I have turned the S 0n back on and cant get passed the bootloader finding the "correct" PC36IMG.zip file. it doesnt find it and says wrong image. HELP
What image are you trying to flash? You will need the actual s-on tool from unrEVOked site, just using recovery to toggle doesn't really do it. Then you will have to flash a stock non rooted ROM. Then run HTC software update. RUU is much easier, why no USB?

[Q] Rooting troubles

I've rooted my Droid X numerous times, but I'm having trouble rooting my Evo 4G. I had it rooted once, then an air-push update did it before I could stop it.
S-OFF
HBOOT- 6.16.1002
Radio 2.15.00.05.02
Android 2.3.3
Baseband 2.15.00.05.02
Software 4.24.651.1
It still has S-Off, but I'm not sure what I can do without risking somewhat permanent damage, seeing as how I don't know much about rooting this particular phone. The one thing that confused me was the Hboot version, I couldn't find a guide or anything for it anywhere.
Anyways, I was wondering how I would go about rooting the phone again, and if possible flashing a rom I found with is basically an enhanced version of the already installed OS.

Pardon my ignorance if this has been asked before, and thank you in advance for any and all help!
I think if you're still s-off you just need to flash a custom recovery again
We're comin from a pure power source.
Yup your s-off so just flash a custom recovery and then to gain root flash via recovery superuser and superuser binaries. You can find those at androidsu.com in superuser. Make sure you download the one for gingerbread

as for the hboot version, dont worry... that what it gets changes to when you root with revolutionary.

[Q] Complete Stock - Non Rooted and S-ON

Hello all, First of all I want to thank this enormous community for their massive support to the mobile platform.
My question has been answered many times but there is a problem that I am facing while doing it particularly with my phone,
I currently have unlocked bootloader with S-OFF and I am running 4.1.1 Jelly Bean RC3 custom rom by The Albinoman. I am now getting an upgrade and I want to give my phone to my younger sister with stock rom and S-ON with locked bootloader,
I managed to get to Froyo and GB version 4.06.605.3 with RUU/PB31IMG.zip images and got S-ON with locked bootloader. However my system refuses to update to 4.08.605.2 version.
The phone downloaded the update OTA but does not restart to install it. Sometimes when it restarts, It gives the triangle with exclamation error.
I tried flashing the it as update.zip from stock recovery and custom recovery as well, but it wont just install it. Be it S-ON or S-OFF or locked bootloader or unlocked one.
I tried to update to 4.08.605.2 from froyo and gb 4.06.605.3, but to no avail. I also tried running 4.08 RUU with 4.06 installed. The RUU would report a success but the software still wont be updated on the phone.
Do you have any recommendations on what to do?
Your help would be really appreciated

First, were it me I'd keep S-OFF and bootloader unlocked. The phone stays more useful that way, and it's your sister, not a random stranger.
Flash a stock ROM from recovery and call it a day.
That said, the RUUs should flash unless they're trying to downgrade hboot. Perhaps that's the problem?

Flash this http://dinc.does-it.net/Stock_Images/4.08.605.15/PB31IMG.zip thru hboot. It is the latest officially signed ruu.
