Hello everyone !

Recently I purchased an 80 platinum tablet which I didn't like too much due toits Android felt really buggy and irrespomsive somehow. I read that it has a similar architecture to the Onda v812 so I flashed it with the latest Kasty. The difference is like night and day, Onda firmware seemed to be very stable and way faster and responsive, but the camera doesn't work as they have different cameras.

I wonder if someone knows how to roll back as Arches doesn't provide firmwares with IMG format plus the built-in Onda local update app fails to verify the Archos zip package.

Long story short I have two requests:

1- possible way to roll back

2- someone with ROM tuning knowledge who can instruct me onto extracting camera files from Archos  firmware and add them to the already installed Onda OS.

Other than the camera, onda firmware is way better and highly recommended and everything else seems to work just fine

The following users say thank you to AZkiller7 for this useful post:

Hi man,

I have extracted some camera lib from original ROM and I would like to try.

But I can't flash the latest Kasty : V812_Core4_v4.4_v1.img

- With Batch Tool : loading failed

- Phoenix Suit : my device in flash mode is never detected.

 

So my question is : How have you managed to flash this ?

 

Thanks.

A possible way is the fallowing

First step.
Someone that still has the the original archos firmware installed to dump it using the
dd if cat/partition/partition-by-name-system /sdcard/system.img
same with the other partitions. (this is just an example, i don`t know the partition layout on these tablets)

Reflash everything to the tablet that has the onda firmware.
Ex:
dd if /sdcard/system.img/ cat/partition/partition-by-name-system
sync

Reboot
And you should have now the the Archos firmware back

One requirement is to have ADB working, and also root access, on both of the tablets.. :)
Another one is the partition layout, if the partitions in the onda firmware are different (smaller) then the ones from Archos firmware, this migh raise an issue. But this can also be overcome be resizing the dumped images.
OFC is a lot of work but at least, this is a way.
