Hi guys (and girls?) newbie here, I'm having trouble with the first step of making the stock recovery backup. I'm following these instructions:
How to make backup of stock recovery
1.download dump-recovery-signed.zip and put it as update.zip on root of SD card (e.g. /sdcard/update.zip) *1 *2
2.install update.zip from stock recovery *3
stock recovery will be dumped as dumped_recovery.img and /proc/mtd will be copied as dumped_proc_mtd.txt on root of SD card. keep them in safe place.
All seems to work ok, I press volume up and power on and get into the system recovery menu, select "apply sdcard:update.zip" and "update.zip" on the next menu, and I get a progress bar and messages and finally "install from sdcard complete".
But after all that there's no sign of the dumped files on the SD card.
Any help or ideas anyone?
