U can repack the system.img using mkfs.yaffs command on ubuntu
if u come online then i can guide u on this
I know u wanna make a ROM for A85 using sytem.img but they cannot b repacked even if u succeed to unpack bcoz Nvidia recovery uses different .img decoder thats why i m telling u
But i can guide u on this if u want to learn it for knowledge
But the prequisite is u need Ubuntu

i repacked the system into system.img to test in AVD was by flashing the rom and taking a nanadroid backup ..after that just use that system.img in nanadroid backup and test

well you can follow my method use flash the rom and get a nanadroid backup ....and you will have system.img

 

[ninadchaudhari]

ok so you mean i must first clear the system partition in fastboot then flash the A75 ROM then push the files you want and then take CWM backup ,
Hey that seems to be a brilliant idea !

no i mean make a rom of that system image and flash in recovery.after wiping everything now reboot recovery and take backup ..thats it now you have converted system folder to system,.img

Can we repack in windows?? any method if we don't have recovery ?

 

[ninadchaudhari]

@cool.gautam as i have done in rooting A75 , just get mkfs.yaffs2 then use it ! after giving permissions of 667
the only prob is that Linux !!

For second: pretty easy. Just install guest additions in virtual box and VMWare tools in VMWare.
Add the shared folder and you can copy files

@akshay
Thanks a lot
It worked

Parallels a better alternative for vmware fusion -- do not know on windows though
i personally use Parallels ---> for anything in Linux and any(if any )work with Windows !
it has also a Windows version , have Tried both ,but Parallels is like too user friendly .

Don't if you hv resolved the problem, but,
Why to load your PC with crappy VMs for this ??!!
You can better use the the arm version of mkfs.yaffs2 to unpack/repack system.img. I can't give links 'coz don't hv my PC now, but you google for it and you will get it! You can then use it with cygwin or adb! What you'll need to do is adb push some xbin files, that comes with tool, chmod xbin, and then put your system.img in sdcard for unpacking, or give the dir. for your system folder, which is to be packed. Run commands in shell and you'll get your system.img packed!! I do the same!!
Refer to the results on Google for those commands, 'coz I don't remember them!!!
