this is my Tablet
Bought it from a unknown person
Product # : CL - ARM M7
4gb (supposedly)
Firmware 1.5
Kernel Version: 2.6.25 rockchip version 1.2.7
Build Number: RK-1.3.2.eng.root.20100827.91510
Camera in the front, NO LED, 9v charger., black plastic cover( for if this helps)

The disc says more updates will be available from chttp://www.chinaleap.com.cn/service.aspx.
(the link doesnt even work)
Dont know more tech details


This is what happened, i was upgrading the OS following this steps
but an error ocurred on the middle(think was the usb cable becausei had a lot of issues trying the pc to recognize it.) and now its bricked, doesnt turn on

tried to connect it pressing all the buttons and nothing, the pc doesnt recognize anything

first im gonna get a new usb, if doesnt i managed this steps so far.

i find user:hucqim80 steps to unbrick but its bassed on an APAD ( http://www.slatedroi...v6-0-solved/15/)

what i think i must do its open it, do the needle trick, but im not sure what program to use to put the firmware on it, and if i need more files than the .img file (mine its "from russia with love 2" custom firmware)

Any help would be really aprecciated. thanks in advance

p.s. sorry for my bad english  :)

I am actually the wrong person to ask because I never attempted the needle trick or actually investigate in the different firmwares for the different batches. My suggestion is to attempt the needle trick because it should work for your unit, and attempt to retrieve the original firmware. Chinaleap is down right now, so I wouldn't know where you could get a firmware at the moment. You need to get your unit recognized so you can reflash the bootloader.

should i attempt the needle trick even if my components are not the same? in the video there is a samsung chip, here the only 2 chips with pins are one that has the hdmi and multimedia functions, and the other one says rockchip.

should i attempt it anyways? thanks a lot man

well managed to achieve the needle trick and its recognized now, flashed the russia v2 version, and it turned on but the touch wasnt working >.> it gave an error in the middle of installation, im assuming its that

tryed to reflash and couldnt, and now it doesnt turn on again but its recognized by the pc

when i try to reflash it stays on " error writing id block"

cant pass of that

tryed with rkbatchupgrade, rkandroiddm, and the one that came in the cd, and the same. and with different OS versions and still the same

IM assuming its the cable again, because i got another but used.

gonna buy a new damncable and try in another PC so i eliminate the fact of bad USB port.
