    100% yes. You can try the RUU method at the bottom of the OP if you don't want to use the SD card route.

    I have 2 questions:

    1 - My phone is having the reboot issue and I'm going to bring it back to the store for (hopefully) a replacement phone. I'm worried that my phone will reboot during the flash process to un-root (PB31IMG.zip). If the flash process gets interupted like this - what would / could happen?

    2 - I have a few nand backups that I'm happy with and are mostly recent. If I get a replacement Dinc, can I just run unrevoked, and then restore my latest nand backup? Will everything be the way it was? If not, what would be different? I also have Titanium backups, but I think the nand b/u would be better.

    Many thanks in advance!

    1) I've never heard of anyone having their phone reboot while in hboot.

    2) your nand backups should work, but I've heard of people having problems with the market after doing that. (not everyone though)

    Nice quick response!

    My phone is getting to the point of rebooting after doing anything more than simply checking email, and maybe starting an app or two. Under any type of heavy use, it most certainly will reboot.

    It's the eternal - what if - that keeps me from unrooting so I can have it serviced. Back in my head, I know the longer I wait, the worse it's going to get. I need to do something this weekend about it. Will it brick the phone if it reboots while flashing?

    [UPDATE:] phone never rebooted during flash.. thank god. But it did start to reboot endlessly after it fully cycled on in normal start up.

    It won't brick and I really doubt it'll reboot during the flash. Like sdrawkcab, I've never heard of a reboot when in the bootloader. Give it a shot.

    If the battery is toast it could very well reboot while in hboot. Hboot runs the proc at super speed the whole time your in it. Best to leave the device plugged in just in case.

    Will a factory reset change S-OFF back to S-ON? I was rooted, returned to 2.2 but forgot to run she S-On update first. Now the S-On update won't work and for some reason I can't get the forever3 to work from this PC, and the phone is wiped from the PB31IMB.zip so I won't loose anything. Will that fix it or will it be a waste of time?

    You need to have a custom recovery on the phone to get back to s-on, either flash clockwork in hboot or reroot using unrevoked, flash the s-on file then run the pb31img.zip file again.

    I have now tried reflash.exe on two different Windows XP computers. So far I have not been able to root from either of these PC's. I did a search on Clockwork and got Clockworkmod but it sounds like you must be rooted to install that. If I can use Clockworkmod where can I download it from? I just want a simple fix to root, remove S-On and unroot. Is there any other way to root without using the reflash.exe whick I can't get to work? According to my Device Manager the USB drivers are loaded and showing but reflash will not find my phone and do the root. Thanks for any help.

    There's a link for CWM on this page along with the S-on zip. Recovery can be flashed from the SD card just like when you unrooted. You can do this because you are still S-off. Not sure how current the file is, but it should work. Then do S-on (flash like a Rom using CWM), then unroot a final time.

    Make sure there's only 1 PB31IMG on your card at any time.

    Yes. That's a great way to do it if you have a spare.

    Could you possible explain to me how you used the S ON tool?

    I feel like I'm missing a step.

    Thank you for your help.

    S-on is a file you download from unrevoked's website. You flash the file in clockwork recovery, like you were installing a rom.

    Hey all, read through this sticky and gotta say, what an incredibly helpful bunch of folks!

    I would like to ask what may seem like a noob question (probably because i am a noob!).

    I've been running CM6.1 for a while now, with root removed manually by deleting superuser.apk and Su.apk, in order to get GOOD for enterprise working. Well, recently, GOOD "updated" and is now looking at "something else" to determine if the phone is out of compliance and now won't run. I need to get it running again so I want to revert to full stock but using the most recent OTA. I'm assuming that's what this is, right?

    Ok, that assessed, my current environment is:
    s-ON (recently done via the unrevoked s-on tool)
    2.2.1 version
    2.15.00.09.01 radio
    2.6.32.17 CM 6.1 kernel
    FRG83 build

    Can I use the image file in this sticky to revert to both stock ROM *and* the stock recovery, in one fell swoop, or do I have to reflash recovery separately somehow?

    Also, do I need to temporarly re-root with unrevoked, before running this image wipe?

    Thanks all!

    Yeah the file in the OP will put you back to full stock. No need to root again, just put the file on a fat32 formatted SD card and follow the instructs.

    Thank you! And just to clarify, when you say "full stock" you mean not just the OS/radio, but also the recovery? This will replace clockwork mod with stock recovery?

    Thanks again
