Thumbs up imgRePackerRK working very well
Hi,
Thank you for this wonderful piece of software.
I tested it on windows 7 64 with an official image for 97RQ tablet (found on slatedroid)

So this is RK3188 tablet.

I used "imgRePackerRK tablet.img",
then with th system.img in the dump/Image folder, I was able to mount in ubuntu and modify build.prop and modify some apk as well.

Then, i made "imgRePackerRK tablet.img.dump",
and the image was built correctly.

I flashed the img using RKBatchTool V1.6 and....

Works perfectly !

So thank you very much for this tool RedScorpioXDA.

Cheers,
sam

Hey, I confirm your tool opens bootloader images for Rockchip images. It works both ways (packing & repacking)

Do you plan to be able to open images that are done with "dd" command ?
e.g. when rooted in android terminal, sending the command:
Code:
dd if=/dev/block/mmcblk0 of=/sdcard/mmcblk.img

Thanks !

To get such image, please follow the link here:
http://forum.xda-developers.com/show...php?p=31141300

The image seems to be a FAT32-LBA
If I do not specify count / skip parameters, I get an image of 4Go (I will not put here).

Instead I tried quickly to make an image of 1024*4ko (4Mo)


Is it enough or do you ned more ?

Unfortunately, I still can't post links due to posts <10.
Firmwares images for RK3188 can be found on slatedroid on N90FHDRK topics.
Hope I can put links in next posts !

And thanks for the explanation. This means there is no recovery partition... But what happends when flashing an image without recovery partition ? the existing is not replaced or it is erased ?
