Can anyone help me downgrade frg83 to frf91 . i have tried renaming the frf91 build to passimg.zip . powered down the phone , held the volume down key and power button. it checks the passimg.zip but then doesnt prompt to update the phone .
Where are you getting the FRF91 build from? http://developer.htc.com is your best bet.
Thanks for the link!

That link points to a guide to root FRG83. Once you're rooted, you can follow this guide (http://forum.xda-developers.com/showthread.php?t=726258) to downgrade your bootloader (so your phone can accept custom ROMs that require the old bootloader such as Cyanogenmod 6.0) and to downgrade your phone to EPF30. The link to create an image is dead, but the files you need can be found in post 40. Ignore any OTA update prompts you may receive after downgrading. From there, you have 2 options:
1) You can use universal androot (easy to find if you google it) to root your device and flash a custom recovery image using ROM Manager from the market. Then you can flash a custom ROM with root access.
2) You can search for and download the stock update files to update your phone to w/e build you desire.
Post back if you need any help or to let us know everything worked.
I personally followed the same procedure, so i know it works.
Cheers,

I can't seem to find the guide for this. I know it can be done....or am I crazy. I rooted a friends phone this weekend. Tried to use unrevoked but it wouldnt work until I down graded froyo. He's rooted now. But still want to downgrade his hboot. And for the life of me I can't find the guide.

I think maybe this is what you want. It installs the eng hboot and amon ra recovery in one shot. The updated file with ra 1.8 is in post 18 in that thread. There's a guide in the first post. The only thing I can think to add is that you'll want to have a rom on the sd card ready to go. The reason being, it might boot loop after the install (mine did) and the only way I know to get out of it is to flash a new rom (or reflash the current one).
I can't post the link or i would just do that.
In the EVO 4G Android Development section, the post you want is called 'ENG bootloader (0.76 needed for CM6) extended fastboot commands'

Zikronix, I have just downgraded my HBOOT from .97 to 0.76.2000. (In fact done this a couple times both from 2.02 and .97). In case you still need this.. below are the steps.
1. Got my replacement EVO today (hboot .97, 3.29.651 build, 1.71 PRI)
2. Rooted it with this method using default (clockworkmod recovery)
3. Rebooted and flashed Amon_ra recovery (optional.. my preference)
4. Copied the correct Eng hboot file (renamed as PC36IMG.zip) to my sdcard, rebooted to bootloader, Eng hboot zip was flashed, I accepted update, done. Rebooted into recovery.
5. Flashed my favorite root ROM (this is necessary bcos the change on hboot does something funky to your existing rom, so you can only reboot into bootloader ... not sure why, some dev should be able to explain more)
6. Done.
I updated to the gingerbread-sense2.1 and lost my root. I was wondering if there is any way to root or go back to an older image version.
I dont think there's a way for you to reroot until a dev or somebody posts up a new root method for this update.
Right. Thanks.
I'm in the same situation.
Upgraded to 2.3.3 OTA and lost root.
Running the Android 2.2 RUU exe to downgrade fails with 140 bootloader version error.
Running the new Android 2.3.3 RUU exe installs just fine on top of itself.
I don't have clockwork installed and w/out root don't see a way to do so.
The restore zip from SD card method (http://forum.xda-developers.com/showthread.php?t=971550) also does not work - never get the "push vol up to update" option.
Any other suggestions?
P.S. When I get to bootloader and select recovery, screen shows this triangle with exclamation point icon. (pic attached). I would have thought "recovery" option should give me some more options, not just die like this...
I believe they locked the bootloader with the new OTA update. You will have to wait til someone comes up with a new reroot method.
P.S.
The devs already made a flashable rooted stock GB zip. The same day.

Could someone please point me in the direction of where I can get the Evo 4G 4.22 stock recovery image?
Stock recovery is no recovery,what exactly are you looking for?
Sent from my PC36100 using XDA App
I am rooted and have CWM installed. I am looking to put back the stock 4.22 recovery so I may install the the 4.24 OTA update.
I like to keep my Rom stock and prefer to install updates via OTA.
If you take the 4.24 OTA you will no longer be "rooted" Look for one of the rooted ROMs and flash it
Yeah,what he said
Sent from my PC36100 using XDA App
I am using the Unrevoked root method and no update (3.70,4.22) to date has unrooted my phone.
I have simply been restoring the current version of the stock recovery, which I have previously found on the internets, and then running the OTA update as normal. Once done I install CWM and the latest SU updates. Works great.
I would like to perfrom this method once agian to install the 4.24 update and all I need is the 4.22 stock recovery.
If you don't want to be rooted anymore, then just accept the OTA - it'll override your current recovery with the stock recovery, which is actually a lack of recovery.
But as others have said, you won't be able to root again unless you've ran unrevoked or unrevoked forever and remain s-off. In that case, you'll have to flash a recovery and then flash the rooted version. So if you want to stay rooted, you might as well go ahead and do that. You should be able to just wipe cache and dalvik and install, so the end result will be the same but you'll be rooted.
I hope that made sense...

You probably want this:
http://forum.xda-developers.com/showthread.php?t=1133379
This is the actual update, but rooted, so you can keep your CWM recovery, get the latest update that was made OTA, but remain rooted. You don't want to just accept the OTA if prompted, your root will go away.
Once you've downloaded it (and the radio update as well), follow the instructions here:
http://forum.xda-developers.com/showpost.php?p=14933526&postcount=31
Thats the problem. I cannot install the OTA 4.24 update with CWM installed, nor can I install the update manually, via renaming and then update method, as it will error out during install.
OTA updates will only install if the proper stock verion of recovery in installed, hence I really need the 4.22 recovery.
Installing OTA updates when using Unrevoked does not change S-OFF, it only overwrites SU which can be easily reinstalled. I know as I rooted my evo way back when it was version 3.26 using unrevoked 3 and have installed every OTA update since using this method and still have S-OFF
Thanks, but I do not need to go that route. My method will update as normal and I wont have to wipe my phone.

And you won't be rooted anymore. There are only about 3 thousand posts telling people this, and most AFTER they found out the hard way. There are stock Rooted ROMS based on the recovery, as in STOCK! but still rooted, and up to date.
BTW, there are also a lot of posts detailing how the OTA made their phones worse, but if you want to be a hard head, go ahead and bury yourself, but don't come back crying when you figure out.
how come every other incompetent noob can manage to get their phone back to stock and permanently locked/unrooted, yet I cannot manage this feat intentionally?
if I intentionally flash the 4.22 zip from shipped-roms will this eliminate my root and recovery?
well install the 4.22 update from recovery didn't work... it aborted with some error.
ARGHHH!!! SOMEONE HELP ME LOCK MY PHONE PLEASE!!!
I appreciate the heads up, but if done correctly, it does work and has worked great for me the past few OTA updates.
I am aware of all the potential problems and am not the only one successfully installing OTA updates on a rooted evo and staying rooted.

Bottom line is if you change back to S-ON, and apply the OTA you lose root forever (or until Unrevoked finds a new backdoor). If you leave S-OFF then you can downgrade, and reload a recovery. The stock ROM's you'll find here (ex. Sprint Lover's) are stock, and rooted. They pretty much the same thing you get over the air. Don't be a lid..
I downloaded a from shipped roms the last rom for my evo and downloaded the s-on tool. Ran the tool then connected my phone to the computer and ran the RUU i donloaded. Fully stock unrooted locked phone
I am a noob
First learn the correct terminology for what you are tying to achieve. There is no 4.22 recovery that you can just flash, there is a 4.22 ROM and a 4.22 RUU.
Then check out the WIKI and FAQs these both contain the info you are looking for .
Not trying to be mean. Just do some research before you mess up your phone and come here asking for stuff that doesn't exist.
4.22 ROM = just the ROM
4.22 RUU = .exe that runs on your PC to FLASH your PHONE with new radio, recovery, hboot, rom, etc

Well said
This is what you want to do to get to the latest OTA STOCK no root
* if you leave S-Off you can re-root *
Is it even possible? Everything I have found have said that you have to downgrade back to 2.2 in order to root your DInc. Is there any way to root a HTC Droid Incredible 2.3.4 (Gingerbread), without having to downgrade the version?! Thank you.

You can root without downgrading. You only need to downgrade to get s-off. Just unlock your bootloader and fastboot flash cwm recovery, then flash superuser thru recovery and you will be rooted. The only way to get s-off is to downgrade. However s-off is reccomended, and only requires a few extra steps to get.

Wait wait wait. I was rooted when I had 2.2, but just upgraded to 2.3.4 when i finally found a fix to the error when downloading it after hours of looking online, which took away the root. So S-OFF is already there. But umm...you completely lost me after that point.
How do I unlock my bootloader and fastboot flash cwm recovery? And how do I flash superuser through that recovery. Im not very tech smart, I can follow on screen instructions, but I dont know what any of this stuff means haha.

If your s-off you just need to flash cwm thru hboot. Download this file http://dinc.does-it.net/Recoveries/CWM_5.0.2.0/PB31IMG.zip, and place it on your sdcard in no folders. Pull the battery, reinsert, and hold vol down and power till a white screen appears (hboot). It should find the file and prompt you to press vol up to install.
Once cwm is installed, download this file http://dinc.does-it.net/Superuser/SuperUser_3.0.7.zip, and place it on your sdcard. Then go to hboot again and select recovery. In recovery select install zip from sd card and select the su file. Once flashe you are rooted. Once you boot up, install busybox from the market, and go to the superuser app and check for binary updates.
