At first look this seems quite doable, as the system image is directly exposed in the firmware archive.

Still, there's a checksum in the package that would not compute corrected with a modified rooted system image, so I need to figure out first if this can be fixed...

 

thanks you so muck. and I hope you try  to  find how to root that chip... save and sound . hủra hura

Globula,

The firmware for the U55GT is actually available here: 

http://www.51cube.net/ch/DownShow.asp?ID=178

It's a phone, not Rockchip based, the system image is available in the firmware, but there's a file with checksum of the images. It's may be a bit risky to try flashing the phone with a modified system image with the checksum from the original one untouched.

Cheers.

from up to now. I only use frimeware in http://www.arctablet.com because I alaway belive this site, so I am worry about other frimwares

hic. I still havent known enter U55GT cube recovery. or up room this device

I found a way to update the checksum for the a modified (rooted) system image, I should be able to prepare a custom firmware in the coming days if you want to test it.

I can't be sure it will work as I don't have a U55GT device to test it.

Cheers.
