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 !

Sam

Please provide an example of such image

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 ?

Hello,
when unpacking a rom for RK3188 tablet, i noticed the backup image is not extracted:

It says: backup (RESERVED) skipped

any explanation to do job ?

Thanks

Unfortunately I have not found images in this discussion. Can you provide a direct link?

powerpsy said:

This means the file is absent in firmware, the partition name is reserved

powerpsy · Jun 14, 2013

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 ?

sorry but how to pack system.img again?

first i mounted img file to directory made some modifications but i could not pack the directory again
second i tried to mount img file to a hard drive (dev/sdb1) and did
dd if=/dev/sdb1 of=system.img
but this time system.img file size was long as partition size.. but longer than original system.img
than tried dd with to bs and count parameters but no success.

what is the point to pack system directory to img again?
thanks

knng · Oct 30, 2013

nevermind, figured it out.
