ClockworkMod (CWM) Recovery easy install for RK3066 and RK3188 -- TWRP/CWM Flash-Tool and root for RK3288
Please donate to support OMA and CrewRKTablets firmware work, thank you !
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...

it would much easier if you try this, and upload the results somewhere

nangiuhoaGlobula,
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.

Is more complicated on a MTK chipset, even if I provide you with a boot.img that allows you to root the tablet, you cannot flash it via fastboot.
Have a look here
http://forum.xda-developers.com/showthread.php?t=1982587
And here

Le: I just saw that the scatter file it is included in the firmware so in theory if you download the tool, you should be able to flash only the boot.img, then push it to the tablet.

nangiuhoaI 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.

Can you share a link, maybe someone else want to root this device also.
As an alternative, I will post a custom pre-rooted firmware to test later this week, work almost done
