[Q]stock reflash complete - bootloader cycling

I was able to successfully flash my stock nandroid through amon ra. But now every time i boot my evo it keeps going back to boot loader. Am i in trouble?

I had this happen to me, and what I was able to do is this: I pulled the battery, then booted into recovery. I wiped data/cache/dalvik. I then flashed one of my nandroids, and it booted up just fine after that. Do you have more than one nandroid? You stated that you are using amon RA, did you use amon
RA to create your nandroid backup? If you used clockwork to create the backup, you need to use clockwork to flash the backup, they are not interchangeable. Hopefully this was helpful to you.

After going about... i think it has to do with the hboot being .76 insted of .79 which is what is suppose to be for 2.2. Or am i wrong? - and every time i try to do the hboot update it keeps telling me an error about a update file, cant figure it out.
Yes i have other nandroid's but, i'm really wanting to get some stuff back from my original stock 2.2. I try doing a titanium backup, but it just kept telling me i wasnt root, but i am.
FIXED!!! It was the bootloader. Spent a good time trying to look for a flashable hboot, and finally had to restore my phone back to stock 2.2, then root and restore. The solution was here, the files.

[Q] Problem with restoring nandroid backups.

I have CM6 installed, Hboot version 0.76.2000 I did a backup before flashing this hboot and installing CM6, I want to go back to the backup I did. When I try to restore the Nandroid backup it fails stating that the restore failed. I am wondering if it is because of the new hboot, and how I can get back to the one I was on. I was stock sense with newest OTA. would like to pick up where I left off and continue on. Any help?

I've heard that nandroid backups are specific to the HBOOT version they were made on.
Example, Fresh 3.3.0.1 on HBOOT 0.93 backup will not install on a phone that now has hboot 0.76.2000.
Everything should be fine if you can get back to the HBOOT you had. I don't know myself how to do this, but I believe you'll have to find a PC36IMG.zip file that has the appropriate HBOOT and put that on your SD card. Then boot into recovery and let that PC36IMG.zip run and install the update.
Someone who has actually done this needs to chime in.

Can someone explain hboot ? does it matter what version you have ?

Rooting issues

My evo got pretty ****ed over the past day, originally I rooted it by installing the hboot drivers then using unrevoked,I assumed everything would be done from there, I never got to flash Amon ra or any custom roms so I wanted to try it out, every guide I found involved using adb shell and a Tom of other steps I never used while originally rooting.
I got so fed up with all the error messages that I decided to start from the absolute beginning and root again and then try unlocking nand, one method involved me putting all these files on the sdcard and using adb a lot, I followed all if these steps exactly and DEFINITELY DID A NAND BACKUP but then after rebooting in one step my phone went back to eclair 2.1 and all my info was deleted and now its as if I bought it today, its not even rooted anymore so all the apps I backed up with titanium I can't even access anymore since it requires root
One step told me to do the nand restore and when I went the folder was empty, I would kill to have my old evo back or at least all my apps, any and all help would be HIGHLY appreciated

If youre back on 2.1, just root it, put whatever recovery you used to make your nandroid on there and then restore your nandroid.

I assumed onceI was on 2.1 I would be rooted again, I tried unrevoked once it was on 2.1 but it just stayed saying "running root" and never changed, and my nandroid restore didn't show up before so why would it now

The root method you used was older, and was the way to go before Froyo was officially rooted. It involved downgrading (which you did) and then rooting 2.1 and then flashing a froyo ROM. It sounds like you made it to the downgrade part and then you stopped for whatever reason. You aren't in bad shape, you just need to get that 2.1 rooted and you're good to go.
As far as the nandroid is concerned, if you made it, then it should be there. You said you never got to flash a custom recovery but you must've if you were able to do a nandroid. Now if you made your nandroid with clockwork you won't be able to restore it with Amon and vice versa, which is where I think the confusion lies. Do you remember what recovery you made the nandroid with?
Your only real option at this point is to root your 2.1 and restore your nandroid with the correct recovery. Check your SD card, if there is a folder called Nandroid then it was made with Amon, and I'm pretty sure clockwork puts it's nandroid into a folder called Clockwork.
As far as why the root wasn't finishing, I'm not really sure because it's been a while since I used that method. It could be a driver issue. Have you installed the proper drivers?

yae the recovery is where the whole issue began, i assumed i was good so i tried flashing amon RA with the terminal emulator and whenever i typed 'su' it always said permission denied, i was rooted for sure so some people said i had to probably unlock NAND and more errors came from there so i tried that other rooting method so i definitely flashed with clockwork and i remember seeing the build name on the bottom as well which makes me pretty happy as well since i found it in the directory which you said under my sdcard with the date name and whatnot so major kudos for that
i installed the hboot drivers before so i assumed i didnt need to do it again but when unrevoked kept staying at "running root" i tried installing again, and on this video online from djr3z he said under 'My Devices' that Android 1.0 would show up where I could click to install it but it never showed up so I've been stuck since that point, are there any other alternative root methods you recommend/should i try updating the drivers? or perhaps i can delete the driver and reinstall?

Check your hboot, are you S-ON or S-OFF? Also, what hboot version are you?

im definitely S-OFF, saw it all the time in the bootloader screen, how do i check the hboot version exactly?

you load it up with volume down and power button, same way you go as if your going to boot into recovery

ok and my hboot version is .76.2000

can anyone confirm if .76.2000 is the latest hboot driver? everytime i connect my phone and check device manager it shows android bootloader interface which, from what i heard, is what im supposed to see
everytime i run unrevoked it stays at "running root..." and doesnt change from there

The latest hboot is 2.02 I believe but you don't want that one, I hear it's a pain to root. Yours is the engineering hboot which must have gotten put on there from whatever rooting method you were using. It's fine to leave that one on there, it will allow you to flash CM6 if you ever decide to. What happens when you select recovery from the hboot menu?
Have you tried downloading ROM manager from the market and using it to flash clockwork? I would give that a whirl.

when i select recovery from bootloader it gives me the black screen with the phone and red triangle, i started button mashing and it seemed like a recovery image but it said 'Android system recovery <2e>' with a few commands like wipe/reboot etc.
i was trying the clockwork before, i installed rom manager, then tried "Flash ClockworkMod Recovery" but it kept giving me error messages about attempting to run privilleged commands, assuming that means im not rooted again
i dont even think i have the clockwork recovery image on my sd card, it does however show my amon RA one, but there's no point in flashing that if the clockwork has my nandroid backup right? and couldn't i just put the clockwork recovery image on my sdcard from online somewhere?

Try this- Download THIS FILE, put it on the root of your SD card, and boot into hboot. It will automatically find it, load it and ask you if you want to run it. Choose yes and let it go. It *should* install clockwork recovery on your phone. If it doesn't work, no harm no foul and we can try something else. If it does work, you should be able to restore that nandroid that you made. It will only work if you are S-OFF, which you say you are so it's worth a shot.

okay and if it works, before i do the restore should i wipe everything?

It won't hurt but when doing a nandroid restore wiping is not necessary.

so close...your method worked, but i couldnt restore it gave me an error messgae..
ClockworkMod Recovery v2.5.0.1
Checking MD5 sums...
Erasing boot before restore...
Restoring boot image...
Error whille flashing boot image!
takes me back to the main menu of the recovery =\
do you think it has to do with me still being on 2.1 rather than 2.2?

So you now have clockwork on there? That's a step in the right direction! Try restoring your nandroid once more and if that doesn't work, you can flash a ROM and then restore your titanium backups.
It shouldn't matter what ROM you're on when restoring a nandroid. Do you remember what hboot version you were on when you made the nandroid? If I remember correctly that could cause an issue but I'm not entirely sure about that.

hmm i cant even get out of the bootloader screen now though..even when i reboot it takes me straight to bootloader
and also if i flash a rom will have to be designed for 2.1 since im still technically on that?

no idea about the hboot version =\ just assumed it was upgraded to the most advanced version when i updated the driver
but i cant even put any ROMs on my sdcard now because i cant even leave the bootloader screen?

No, flashing a 2.2 ROM will upgrade you from 2.1, it should work fine. You must have made your nandroid on a different hboot version then the one you have now.
What I would do in this situation is run the 3.29 RUU found HERE which will bring you back to full stock, and then you can run Unrevoked and reroot it. The whole process should only take you a half hour or so. I don't know if you will be able to restore your nandroid because of the hboot discrepancy, but at the very least you will be able to restore your titanium backups.

[Q] Nandroid restore after OTA - is it possible?

I had my Evo (android 2.2) rooted with unrevoked forever but had to take it in to Sprint. I unrooted with the S-ON zip and then flashed the closest PC36IMG.zip that I could find on the forums. Finally, I did a factory restore and applied the OTA (3.70.651.1).
I've got the phone back now, but ever since the flash my 4G refuses to connect. I suspect I might have messed up my RSA keys.
I have a recent nandroid backup, but I'm afraid to restore it because the PC36IMG.zip updated my radios. My question is: is it safe to restore?
I'm aware that I'll have to re-root and install clockworkmod again.
I'm a long time reader, first time poster, and I appreciate your input

Heck, if you're able to re-root, it wont matter. Once you're S-OFF, simply reflash the radio, PRI, NV & WIMAX that you had before you unrooted and then restore your nandroid backup. You *should* be fine afterwards. By the way, the radios are independent of roms so it's not like your baseband, PRI, NV & HBOOT was backed up when you made your nandroid backup with the WIMAX being the only exception and that is if it was selected to be a part of the backup. Having said that, if you are not able to re-root then I would not attempt to restore a nandroid backup.

Alright, thanks! I won't be able to downgrade the hboot, but I'll give it a try nonetheless. I'm assuming that bricking the phone's unlikely as long as the downgrades themselves are successful. I'd just have to reinstall what I've got now if the backed up ROM is incompatible, right?
Edit: I've got the wimax.img in my nandroid backup

If you have the OTA, and its s-on as you said, you can't root it as of yet.

Do you know which OTA that was? I have a feeling that I didn't get the latest one, since I'm not on Gingerbread.
I did get some strange results after running Unrevoked - I have S-OFF but I get the red triangle/exclamation point when booting into recovery and I don't have root.

If you are S-Off then you just need to reflash the recovery. Once you do that you should be able to reload your nand backup.

It seems like you do not have a custom recovery flashed.
User ROMManager to install Amon or Clockwork.
As long as you are S-Off still, then you will be able to reboot into the recovery of your choice.(Didn't see you didn't have root)
Try rerunning UnrEVOked.

You don't have a recovery; http://dl.dropbox.com/u/19699565/PC36IMG.zip Download that, place on the root of your sd card, boot into the bootloader, apply update, reboot, reboot in recovery, and you'll be on Amon_ra 2.3 recovery.

I've tried UnrEVOked three times, all to no avail. Still the same result.
And yeah, I tried ROMManager + Superuser from the Market but they didn't work. Definitely no root.
I figure that I should be able to push clockworkmod using fastboot from my computer. I'm having a bit of trouble tracking down the right recovery image though.

Ah that one got posted as I was typing... thanks for the upload. I'll try it now.

It worked! Thanks teh roxxorz. Now I'll go ahead and actually get superuser, install CWM, then restore the backup and hope for the best with 4G
Update: I'm done and everything works flawlessly. Including 4G. If anyone has the same question, I can tell you that it's definitely possible to restore to a nandroid backup, provided that the radios are reasonably close to the originals.

ENG Bootloader and restoring cwm backups?

Ok i have a question. I just recently came apon ENG_Bootloader_0.77 (Enginering Hboot), after looking for over a year. I figured it would be usefull for those times when you need the extended fastboot commands to fix a partition etc. My problem is If i try to restore a nandroid i get "error while flashing boot.img". Does anyone know why a nandroid made on hboot 0.92, will not restore while on hboot 0.77? If i got back to hboot 0.92, it restores just fine. Flashing roms works, but i would like to be able to restore my setup, and keep the ENG 0.77 hboot.

question do u still have a copy of this hboot? i wanna test it
