NANDROID RESTORE WITHOUT FASTBOOT?? - does it really work?

---

ok so im confused. I was reading the "how to flash cupcake" thread and came across this post by ridli. i tried following the instructions below but they failed, it seems like it works for him. if this truly works then there is no need for fastboot to reflash a nandroid back up. please help. thnx. BTW dudes .8 G build is awesome. (posted from my G1-modded w/root and gloss suite theme)

I tried the below on my G1 using recovery mode from JF-RC33 and i get:
error opening /sdcard/bu/system.img: no such file or directory.
I have checked the sdcard and its there, please help.

1) Download cupcake
2) copy IMG files to a DIR in your SDCARD
3) reboot the phone in recovery mode
4) press ALT+X for go to console
5) #mount -a (for mount all partitions, without this you dont have flash_image becouse it is in /system/bin/)
6) use flash_image for flash the partitions

#flash_image system /sdcard/<dir>/system.img
#flash_image boot /sdcard/<dir>/boot.img
#flash_image userdata /sdcard/<dir>/data.img

7) #reboot

Optional: Do a backup of the phone with nandroid from the recovery mode, this do a img of system, data and boot partitions of your phone and copy to your sdcard. If you have any problem you can reflash your phone with you img.

It didn't work for me either, but it said I could not remount system as r/w because it was busy.

Anyway, I find instructions on how to do it via PC a lot easier. And if your phone would not boot, and you are stuck without backup, you can always pull it with adb.

Karolis:
System shouldn't be busy in recovery mode... also, it shouldn't be mounted if you're trying to write a fs image
And... no, if your phone can't boot, it can't boot. That includes starting adbd.
If you can enter recovery/spl, it's booting just fine.

flak0:
Have you checked the sdcard from the shell in android, or from your computer?
If it's the latter, you should make sure you can access the file from android.
I would recommend that you copy the flash_image binary out of /system (and /data), because you're rewriting that partition

Okay, don't use the forums when on a bad connection... my browser thought it lost connection, and decided to refresh, and send my post again... *Looks for a delete button*

Ummmm actually this does work if you do itcorrectly. Note to self no bashing people that are just trying to help.

so how is it done?

And could a Gscript or similar be written to do something like this? I'd be psyched to have the option to restore my phone on the fly. And of course, if you could do that, what would stop you from having a Nandroid restore point saved for a number of different builds? I would love that.

Out of curiosity, and I've never tried this method myself, are you just entering the following exactly?

#flash_image system /sdcard/<dir>/system.img
#flash_image boot /sdcard/<dir>/boot.img
#flash_image userdata /sdcard/<dir>/data.img

Or are you changing <dir> to the directory of your nandroid backup? Because if you aren't it certainly won't work.

But it would be very unsafe to flash a fs image when the partition is actually mounted and your gscript is probably in it.

the only way is to do it in recovery mode.
one little problem though: i copied flash_image to /cache and chmod, but the shell kept telling me no such file. why is that?

flash_image is a binary, should not be moved. why did you move it to cache? of course it wont work...
