Which CX919II ? New type ?

[jiepiewie]

I've received my CX919II today. It's one of the orange versions with the 2 antenna's. I've read some more on this board and couldn't find my board it seems so i'm a bit unsure which firmware to flash. After opening the case it is an RK3188T and i found the following text on the board:

CYX_809III_RK3188
V2_1 20140208

Here are 2 pics of the pcb:

Anybody an idea which stick this is exactly? Which firmware can i flash without bricking this stick ?

hi,

Same hardware, I advise you to do not flash for the moment if you do not want to lose WIFI and BT

If you have stock firmware or find a compatible firmware, i'm interrested

I was playing around with this stick yesterday and dumped everything on it. So yes, i've got a complete dump of the stock firmware. Could that be of any use ?

My seller can not provide it to me so I would be indeed very interested in this dump if you can make it available !!!!



I'm sure it will also serve the community in the near future until a functional custom rom

No probs. I will upload it to my dropbox this weekend and share it with you/others. Or I can upload it here if possible. I just have to check if the dump i made don't contain my Google-account data :-)

I just followed this excellent guide http://www.freaktab.com/showthread.p...ew-RK-2-1-tool

I'm just uploading the most important dumps without the userdata.img & user.img because that last one alone is almost 8GB. What i can upload is:
parameter.txt
backup.img
boot.img
cache.img
kernel.img
kpanic.img
misc.img
recovery.img
system.img

Will this work ?

[kristoma]

I'm a noob in flash rom, I have my dongle since 1 Week.


I do not have enough knowledge to confirm that it will work.
I would do the test.


Typically i found in flash tools the following files:


parameter
misc.img
kernel.img
boot.img
recovery.img
system.img


And a bootloader for a kitkat rom example


RK3188Loader (L) _V2.13.bin


Someone can confirm it will work or if it's possible to mix files (this dump kernel with an other rom and bootloader ??)

[gabrago]

this is stock rom

@jiepiewie : I'm still interrested by your dump for :

parameter
misc.img
kernel.img
boot.img
recovery.img
system.img

Tx for your help, but i think that i can't solve this by myself.

I want to try to root and insert wifi module but i don't know if i'm on the good path and i'm lacking of time to watch this.

If someone can upload somewhere (dropbox, googledrive, mega ...) a complete backup firmware for this hardware ???

for example :

parameter
misc.img
kernel.img
boot.img
recovery.img
system.img

Please be sure that your loader is version 1.24,
I have put it in the rar file.

You are my savior!
I do the test as soon as I find the time and confirm back here just after.

[kristoma]

Bad news !

Maybe i miss something, but no video signal at boot

Your boot.img ans kernel.img have exactly the same size, i do not Know if it is normal ?

I'll try again an other day ...
