Readme for the Allwinner A10 Multi-Device Rom Testing Forum

Greetings,

The Allwinner A10 is popular among a great many Chinese made tablets. Developers and experienced users have found that a firmware, stock or custom, could be used among different makes which have the same or similar hardware's. Since it is not common for any individual to have access to multiple tablets for development and/or testing, this forum is created to provide a place for testing and reporting compatible tablets to certain firmware, stock or custom.

Several advices to those who wish to try a firmware:

Before testing:
. Check the tablet specs. i.e CPU, screen size, screen type, memory amount, etc . . . A firmware for a 7" is not likely to work on a 10", and one for ips screen is not good for a regular screen.
. Save the original firmware in a safe place and be prepared to know how to restore in case of trouble.
. Understand the risk and is willing to accept it.

Reporting:
Your test is valuable to you, and to a great many others. Hence, sharing your result is much appreciated. The report should have, at the least, the following details:
. Firmware name, revision, and post/download link.
. Tablet name with cpu + screen + ram specs.
. The procedure that was used to flash. A description or a link to the procedure would be fine.
. How did you determine that the firmware is compatible, or not, to your tablet ? What apps or games have you tried, if the flash was successful, and for how long ? The more details that you can provide, the better.

I welcome any additional detail that could be added to make this guide more useful.

I have already lost the original FW for my coby MID1042 so I am willing to test any and all goodies you come up with It seems that this little tablet is tougher than it looked as I have flashed pushed pulled slammed sneaked and generally abused its mental chambers hard for the last 2 or 3 week
ATM I have it back to needing the screen re calibrated everything else seems to be working.
If anyone has any info on how I can replace the touch screen functionality I would appreciate this as i have no original FW for this unit I need to get it back in working order then create a dump specific to it then I can experiment with it a bit better

Out of pure curiosity I opened my coby MID1042 and copied all the numbers and tags I could find there also I checked coby's web site and I found what I viewed as an Inconsistency so i ask what is the difference between Allwinner A10 and Allwinner Cortex A8 According to coby I purchased this unit:
Processor
CPU Type Allwinner Cortex™-A8
CPU Speed 1.0 GHz
According to what I seen inside the unit and copied down I have this unit:
Allwinner tech A10
C4024ca 24G1
PN:ASM-700-R768 V11

please explain to me what I am looking at is this the same thing in different terms or have I been trying to flash the wrong firmware?
