Extract\Dump Rom & Kernel for tablet. - Android Q&A, Help & Troubleshooting

Hi one of my friend has 1 china made tablet which has no clue of its stock ROM over the internet
That is an Allwinner A13 Tablet with Android 4.0.4 into it
We are trying to make a custom ROM for it & for that we need to DUMP or Extract everything from the tablet
So if during the time of testing if the tablet soft-bricks we can re-write ROM & Kernel to it
And also we are trying to modify the kernel to make OC available with more CPU governor
We managed to flash the CWM Recovery into it so we can backup the ROM with it but it cannot backup the kernel
So is there anything we can use to DUMP the ROM & Kernel & make an .img to flash the tablet by burning it to SD Card?
Thanks!
Manthan Bhasvar.

Chuwi v88

All hello, such question, I have chuwi v88 tablet, there is an official insertion, and there is a kernel from oma rom, it is possible to put somehow a kernel third-party on it? Or only together with custom rom?
And still, give please references on tools for rom porting
Thanks
New kernel and tools
The newest versions of Oma's roms contain a new kernel and all of the tools necessary to flash. Once you have flashed, you may use the included flash tool to flash other kernels or other roms. It's all very straightforward. Please see this thread: http://forum.xda-developers.com/showthread.php?t=2310818

Acer E600 flash with another firmware

Hi all! Is it possible to flash the smartphone with the firmware of other vendor? For example, this Acer has CPU Qualcomm’s Snapdragon 400 and Samsung galaxy Grand 2 also has this CPU, GPU is also the same Adreno 305. I suppose something may not work, but what i have to do to flash this firmware for at least to boot? Acer is rooted, CWM is installed. What the issues could I have for flashing and booting?
The second option is to build Cyanogenmod custom firmware.
Any help is welcome
Flashing anything not made for your device will likely brick it. So that's not a good idea. :good:
It would be easier to build your own CyanogenMod than it would be to try to get a Samsung rom to boot on another device.
not possible

Hy! Sorry for my bad english. I tried to port a MIUI7 from the ZTE V5 RedBull (from original miui page) rom and the system is booted up but the wifi, the sound, BT, rotation doesnt worked (not hard to fix, but the miui rom had a security by the original developer so if I modify something in system, I got a popup after restart that this is a pirate version of this rom :S
Thank you for replies!

Could you tell what the sequence of activities you have done? You also have Acer E600 and just flashed MIUI7 from ZTE V5 or the firmware need some changes?

I also have an E600 Here is everything what need:
First you need a stock E600 flashable zip rom. You can do this with dsixda kitchen from the system and boot image.
Download the ZTE RedBull MIUI rom: http://en.miui.com/download-243.html
Rom porting how-to: http://en.miui.com/thread-70745-1-1.html (do every step except the boot.img editing)
Then comes the boot.img
1. Unpack the e600 and the zte boot image with Android Image Kitchen
2. Open the split_img folder in the unpacked E600 boot image, copy and overwrite everything except the boot.img-ramdisk.cpio.gz to the ZTE unpacked boot split_img folder.
3. Repack the ZTE boot image
Reboot the phone to cwm, install the ported zip to phone then flash the modified ZTE boot.img
any update on the custom rom?
have the issues fixed?
thanks.

Port mtk6572 rom without stock rom meta-inf

Hello,
it's possible to port mtk6572 rom to another device (element p402 destroyer mini). Without having stock rom flashable zip?
I found tutorials like this: https://forum.xda-developers.com/showthread.php?t=2701283, but they require stock rom zip.
I have only CWM backup.
Or does anyone have the stock rom?
Thanks for help.
