After a "reset to factory", my phone, a G'Five A68 with a rooted Froyo, has entered into a boot loop.
It's my bad, I've removed some apk into /system and to fix the boot loop, I've flashed a bad system.img dump (using fastboot), so now, it's worse.
Unfortunately, I don't have the stock rom or a nandroid backup, but I've a dump/tar of the /system partition.
I've also a (good) dump of the recovery partition (and maybe boot.img also).
I've build a system.img from the 'tar' using mkcramfs and mkyaffs2 but it doesn't seems to be the good FS type, or maybe, not the good block size.
So, quick question: how to build a correct system.img for my device ?
Is there any informations I can use in boot.img or recovery.img to know the good fs and block size ?
Here is the mtd of the device:
I've tried to retrieve some info using fastboot, but nothing:
$ fastboot getvar all
finished. total time: 0.002s
$ fastboot format system
formatting 'system' partition...
Formatting is not supported for filesystem with type ''.
finished. total time: 0.003s
Thanks for your help.
