Please report any problem with this firmware, I can't verify this custom firmware works as I don't have a PiPO U9T to test it.

kitkat CWM (or ClockworkMod (CWM) Recovery easy install package ) not working on pipo u9t,
I tried using the arctools installer to install it doesn't return an error, but doesn't work.
so I tried to manually flash it from root adb I get this (using the script from arctools installer)
./flash_image recovery recovery.img
and I get
error scanning partitionsfailed with error: -1

using RKAndroid Tool 1.37 to flash reocovery.img 0x00010000 causes the pipo logo then just a black screen on booting recovery .
on a side note the cifs.ko , md4.ko modules cause the tablet to freeze,reboot (probly a kernel panic) when trying to mount a remote share. I have even tried several kernel sources and toolkits to compile the kernel module but all end in the same result a reboot when using the mount command. , the modules will insmod fine though so I'm at a loss what the issue could be.
Don't buy from pipo-store.com.
How to change size space for applications (/data partition) to initial 12 GB and how to see folder androiddata. Tommorow look parameter file in firmware image. Why in parameter type rk3066 and model U8. I download original firmware and see parameter file in original firmware and do changes in moded firmware.
Hello, I followed your steps and everything right in the recording of the new ROM.
I find a serious flaw in the ROM. In Standby (display off) mode, the mobiles do not work data (3G). If we display on mobiles working with data (wifi OFF) everything works fine, but when you lock the tablet (Standby) data almost instant (incoming calls when you arrive) are disconnected.
Programs like whasapp, facebook, ... not notified in Standby.
--- If the tablet is connected by wifi, everything works perfectly !!
This problem is also has the original version (4.4.2).
I've tried different App's with and without root to force the mobile data without good results ... I pushed the data (always) in advanced wifi settings, I've tried almost everything.
Is there a file that you can edit a value not to turn off mobile data?
I repeat that the problem only happens with mobile data when the screen turns off.With wifi works perfect!
daye: "And finaly…. this rom can't install…"
this is rom is update on tablet pc normally, I update without problem!!!! Gps work, but not fine, on three!!!
with this firmware only 7 GB nand flash, but root rights
I get file parametr with official firmware and change this file in this moded firmware and get 12GB nand flash for user data
