Hi!

I try to change firmware from stock to OMA Caynogen.

Download Kernel for u9gt3, change kernel.img.

Erase, Run. Everything looks fine.

But when tablet restarts it's always going to clockworkmode.

I try to apply int and ext fixes but no luck.

I found error - Can't mouunt /cache directory.

Of course when i trying to format cahce or data partition - i see next error:

format_volume: make+ext4fs failed on /dev/blockmtdblock7

Please help!

Start from the beginning.

Complete Erase, flash and then apply format_nand.zip on first boot. If you don't do that, it will not work.

As I wrote, you have to begin from the starting point.

Change kernel.img in rockdev/image folder, don't use you're own recovery.img, use the one that Oma provided.

Copy format_nand.zip to a sdcard and insert it into tablet.

Then make a complete flash, including eraseIDB first, then click Run. It should now boot into CWM. Apply format_nand.zip thru CWM and choose reboot. Now it should boot up normally.

I tried what you propose.

Script can't wipe data because data and cache not mounted. It's pointed to wromg mtblock device.

It's shoild be like mtdblock5 and point to mtdblock6.

 

this i found on this forum (related to u9gt3 too)

Recovery seems to search /cache on mtdblock6 but in stock rom /cache is on mtdblock5.

okay, then we have to try second method of Oma..

change recovery.img to this one:

http://crewrktablets.arctablet.com/?wpfb_dl=1036

 

It should boot up and format all that is needed. After that you can replace recovery.img with the original one and flash only the recovery.img (tick parameters too).

I tryed u9gt4 kernel and u9gt30 - of course problem with screen wrong size.

But tables works without power or USB cable, touch still not working.

Conclusion u9gt3 and u9gt3s - have some differences.

And need different kernel.

It seems there are different revisions in the field. What is your tabs serial-number?

 

Here is a kernel for S/N U9GT3S16GBXXXXXX : http://crewrktablets.arctablet.com/?wpfb_dl=1483
