Just ordered a tablet with the 'Rockchip 2818' chip, my question;

Any custom ROM development going on for this processor?

Rock 2818 ARM 11 600Mhz is what my ordered tablet features, running Android 2.1, possibility to upgrade/root to 2.2?

Thanks in advance!

Who knows, maybe it's only my device; always worth trying to see if 'Angry Birds' will work for you


EDIT"

Anyone seen anything bout this tablet? It's called 'Point of view Mobii 7" tablet Gen II'?
Would it be a possibility to copy the ROM off this device and then access it through a unix system to unpack and change stuff? if so, how would I do it?

I verified CRC algorithm is not changed from RK2808. rkcrc is still usable for us:)

decrypted system.img should be able to dumped from live device.
I think update.img which contains dumped decrypted system.img can be flashed by official flash tool.

I don't have my RK2818 yet. anyone can confirm it?

If you tell me how to do it, i wouldnt mind trying it on my tablet.

do you have official update image/tool for your tablet?
if "no", I don't recommend to do it... it may brick your tablet.

if "yes", then next question.
can you get root rights via adb shell? (no need to install superuser.apk. root shell is enough)
if "no", you need to modify boot partition (boot.img) or get root by temproot method to dump system partition.

Isn't it possible to copy/backup the image off the device itself?

"dumping system.img from live device" is some kind of "making backup".
I'm happy if you answer my 1st question... or you said "no" above?

Z4root can temp root it, but that's as far as it'll go for now.

as I said, root shell is enough even if it is temporary. you can dump mtd partitions on it.

Well then its a no, I dont have the official update image for the device, it's not provided on their website either.

you can make backup of all mtd partition via root shell. you can get flash tool from another RK2818 firmware.
but you can't make backup of RK28xxLoader(L).bin from device. I do NOT think RK28xxLoader(L).bin for another device will work on your device.

I want to know update.img with decrypted system.img can (or can not) be flashed by official tool.

I think you can try to make/flash custom ROM without official ROM/tool.

dump boot and system partition, modify them, reflash them via root shell or old flash tool for RK2808 which can flash specific mtd partition. but it may brick your device.

can you agree to brick your device?

I don't know what will be happen on your device. just asking you can accept worst case.
of course I don't want your device bricked.

Yes, I will accept that if it does happen and try everything I can to try and get it working again.
[/quote]

ok then go forward


I'm not sure what can be done on your device. please tell me

cat /proc/mtd
ls /system/bin

can you make backup of boot, recovery, and system partition?
can you enter recovery mode? (by press key on boot, or adb reboot recovery, or something)
