cappybob thank's once more for the tuto, my U30GT-30H is now running JB4.2.2
The only issue for the moment was h/w acceleration when playing videos : standards players doesn't show videos but MX Player works if you select s/w decoding, or better selecting h/w+ decoding that give very good results.
Thank's to Crew RK Tablets team, and many Thanxs to OMA (O'Master)
giulia.spider : cwm and procedure given by cappybob works fine for me, cwm is not very intuitive but ignoring error messages and installing zip files was good for me.
Spider while booted in Kasty you will need to copy the (2) nand fix files to your external S/D. I have used both nand fixes labeled as the 4.2.2 fixes from the Crew RKTablet site. Load your tools for the build and follow directions and let the tab goto CWM screen automatically. You will see several errors during the process (1) the last_log for recovery, you have no log to be shown until later (2) will be a format error of the external card. Ignore both during the process. Once you have entered CWM goto install ZIP. from s/d, then choose install ZIP. from external S/D (At Bottom of list before go back). Choose the 4.2.2 FORMAT Nand 1st and then the Instd_to_Nand_fix second. Now tab back to the reboot top choice and goto wipe factory reset and data, now when choice comes reboot now.
You are welcome my friend, I just play a lot with OS's. The support from the Crew RKTools is exceptional. Oma and Netlars both are here on this site pretty much every day and they will answer a PM if you have a problem. Have fun, personally waiting for 4.3 next, might even try it myself. Latter.
CappyBob--It isn't yours til you break it--
I haven't even seen one yet, the RKTablet crew, would be your answer on this. There are many work arounds available on their download site. I would say that the team has done their work and go for it. If it works, let Oma and or Netlars know so they can verify and update their lists. Right now working on upgrading to Win8.1 and Mac OS10 Mavericks to check if the rockchip tools are going to work. Later
New issues with U30GT-30H JB 4.2.2
- Bluetooth is not working, I can activate BT but it never find any BT devices. First time activating BT it goes off then on every 30 secs, this behaviour stops after hard power off.
But now Cube power on itself and go to sleep mode repeatedly and I have to power off to keep battery. With BT enabled ot not same problem.
- Google play services complains with a bad installed version and refuse to update.
- Chrome with activation of Bandwidth Management adds spam links in regular websites ! all is ok when browsing this parameter (tested with my own website http://www.oyopi.com)
The last point is worrying...
My next project is to install 4.2.2 to my u30GT-Mini. It is same kernel and processor like U30GT-H. Do you see a change to install this?
Both Cube U30GT-H and U30GT-Mini have different hardware so they have different kernel.
There is a U30GTMINI-MS, it's expected to be different hardware then the regular MINI:
