[Q] Karbonn Smart Tab 7 Help in stock rom backup
I recently bought a ST7 but was disappointed to see no compatible recovery or custom roms for it.
A LITTLE HISTORY:
I did find a Crystal_Root.zip on the net which installed the SU on my tab.
But I couldn't change any CPU settings via the kernel tuner or the rom toolbox (they were buggy and acting up) and it corrupted my system in the end after I modified build.prop to add the windowsmgr.max_events_per_sec.
I triple checked the property name and value in rom toolbox, it asked for a reboot when I tried to save the changes and it got stuck at the boot animation screen.
I had to take it to the customer care to get it fixed (which wasn't very pleasant, had to wait there for 4 hours to get it done).
NOW, THE IMPORTANT BIT:
Is there a way to backup my stock rom and put it in a update.zip or such so I could flash it back on if I have a similar situation in future?
I did try: adb pull / and copied the files over to my pc (but not sure about the updater-script part or do I not need it?)
To an experienced developer, a twrp or clockworkmod port for ST7 would be great and much appreciated. I know there is one for ST8 and 10 but none for ST7?
Maybe asking for too much, a custom rom port of jelly bean for ST7?
P.S. it is my first post here. So please be kind.
