works like a charm. I have installed your custom recovery. Backed up everything with nandroid, tried KeruROM, flashed back my original branded ROM from nandroid backup.
Everything works. I'm not going to try flash back my original recovery mtd, there is no reason to do it, but have a dd backup just in case. I don't know if it is safe to tamper with recovery mtd, cause I'm not sure if it is re-flashed after every system shutdown. I don't think so, cause I haven't found recovery.img in /system.

I have two questions regarding flashing custom recovery. I haven't used this command:

# mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak

cause, i didn't found this script on my phone. Is it ok?

Second question: Is it mandatory to copy flash_image to /system/bin with this command?

cat /sdcard/flash_image > /system/bin/flash_image

Can't we use /data/local/tmp directory and running flash_image from there as we used in the process of rooting the phone? This way we don't have to remount /system in rw and do not have to modify it.


Now I'm going to explore ROM modding ;)

Flash_image doesn't have to be there but for simplicity I put it there so it would be in :PATH. The install-recovery.sh is an evil script that will rewrite a recovery on boot with stock recovery(that only is there on some phones after an official ota update) so rom markers please remove it if it exists.

Any chance the p509 optimus t is similar enough for this to work? I'm willing to be the guinea pig if it should work.

Its close enough it has a very good chance of working but will take a guinea pig to verify. Kernel should be close enough to try. Only differences I saw in the ramdisk of p500 & p509 was model number and lang of en GB and en Us repectively. I had a bad/corrupt dump to work off of on the p509/T. I could use a good dump source with a md5sum to verify its not corrupted in uploading/downloading.

make sure you do this 1st to backup your stock recovery

from terminal or adb shell

dd if=/dev/mtd/mtd2 of=/sdcard/recovery-dump-T.img bs=4096

please upload that dump for me with a md5 too and I'll work on an official.

Can it be done without root? As normal user?
