Hi, I have problems making the recovery, here's how I did it if anyone knows where I could be wrong:
z4root.1.3.0.apk I installed the file and I run, it has created the icon z4root "I opened and I put" Permanent Root "with prior activation of" USB debugging "because it will not let me root , while doing the "Permanent Root" the terminal rein) and after reinciciar I turn to get into the "z4root" and verify that this root because it makes (your device is Already rooted) in the notifications I get (# superuser z4root Superuser Has Been Granted permission), also has created an icon called "superuser" when you open this program "z4root" I select and I put afford. Having done all this I run the program "Terminal Emulator" and putting the first two lines I get the following in the mobile:
$ # mount-o remount, rw-t yaffs2 / dev/block/mtdblock1 / system
$ cat / sdcard / flash_image> / system / bin / flash_image
cat / sdcard / flash_image> / system / bin / flash_image: Operation not permitted
If I put the # on each line as shown below do nothing:
$ # mount-o remount, rw-t yaffs2 / dev/block/mtdblock1 / system
$ # cat / sdcard / flash_image> / system / bin / flash_image
$ # chmod 755 / system / bin / flash_image
$ # mv / system / etc / install-recovery.sh / system / etc / install-recovery.sh.bak
$ # mount-o remount, ro-t yaffs2 / dev/block/mtdblock1 / system
$ # flash_image recovery / sdcard/recovery-RA-GNM-thunderg-1.1.0.img
$ # reboot recovery
I sorry, my English is very bad, I translated with google translator.
