Tím návodem myslíš tohle?

EDIT:
I just took one of my other Next8P's running an Android 2.3 build and did the following to flash this (and it worked):
1.) Unzip CWM_Recovery onto my EXTERNAL_SD
2.) Unzip FLASH_FIRST on my Windows PC
3.) Run RK29Update, check the Loader box, hit Format, then Flash after that finishes
4.) On the tablet, it should boot into CWM
5.) Select Wipe Data / Factory Reset and confirm
6.) Select Backup and Restore, and then select Restore, then 2012-04-18.04.47.45, then Yes - Restore
7.) After complete, select Reboot System Now


It should boot up.


It will give you an error about the NAND flash (internal SD storage) being corrupt, just let it format it and you're good to go.


EDIT #2:
To anyone trying mine or ChristianTroy's ROM in the US, download this file and put it in /system/bin (using Root Browser or Root Explorer or similar...)


Reboot.


This will enable pretty much the full market. Thank ChristianTroy for the tip!
