Guys, I found on xda a firmware for chuwi v88 which seems the same as our cube (HW pov).

The thread owner posted a kernel for our u35gt2 and he tries every kind of ROM : CM, AOKP, paranoid and AOSP

He released end of July a 4.2.2 firmware with multi windows and sdk 2.0. Maybe worth a try.

He is working on a CM ROM (10.1) for now...

If you are interested : http://forum.xda-developers.com/showthread.php?t=2310818 with kernel p.57

I'm still on the last one 4d. Battery drain is definitely worse. I will monitor it further.

 

Metalazzo, have you already tried any of them to the ones linked? Which do you recommend please. Thanks.

I'll try one of those releases

4.2.2 sdk 2.0 and multi windows, which is the last one and one of the best through the feedbacks.

(thanks to cpuz) it seems that the cores are always runing together. No core "shut down", so cpu is always runing almost half speed...

 

edit: seems to me the kernel is the one at fault...

edit²: I tried to change cpu governor from interactive to on demand.

 

But now, battery can't go above 43% :D

It seems that the firmware has ContactsProvider.apk missing. Google drive doesn't work because of that. Also google account synchronization shows an error status because of the same reason. Does anybody have the correct apk? I downloaded one from a thread related u30gt but it doesn't work.

can anyone tell me what is the cpu governor of last 4.1.1 ?

 

edit: it seems the tablet can't enter "deep sleep mode" so cores are always running at 312MHz minimum. :/

Guys, if you're reading this topic, modify your cpu governor using antutu cpu master for example.

Go from Interractive to On demand.

You'll be surprised.

Using your tip, the tablet seem to be more responsive but battery life is more or less the same. Also I didn't have much luck using the XDA firmware; encounter a few issues with them (yes I did use the kernel from the link for our tab).

Too bad for xda firmware :(

I didn't have time to test it :/

Did you post your comments to Oma ? Seems to be a nice guy.

On the topic of cpu governor, going to on demand, the tablet has almost the same behaviour as before.

Loss of 3-4% per night, the battery lasts ~2 days.

Hello, when I plug my Cube U35GT2 in my PC with Windows 7 Ultimate x64, it's recognized correctly (I installed the driver for Win7x64) and it's showed in the RKBatch Tool v1.7 with green icon, then I wait 2 minutes and 2 seconds and then the tablet self-disconnects automatically always.
I want udgrade the firmware but I think 2 minutes aren't enough to do the whole process.

-Does anybody know if it's normal that the tablet self-disconnects from USB after 2 minutes?.

Thanks

Try to use a 32 bit OS version to flash.
On most of the recent tablets on rockhip soc (starting from rk3066 and so on) i noticed that after a period they get out from flashing mode by themself if you don`t actually start the flashing process.
