Convert nandroid backup to update.zip

[mopar57]

I think I have an idea for a long way around.
You up for a challenge?

Use yaffs2 to extract the files from inside the image and then take a working update zip from a rom and just replace the files inside it with the files from the image.

Tbh, its easier to use adb to pull the files out rather than having to make a backup, unyaff's the images, then zip it.

Where do I place the unyaffs .c and .h files? Also- where do I run the command? Device or desktop?

Nvm, I finally got unyaffs working. Unzipped my system.img ... that's my whole rom correct?.. Like, I was rooted on gb; will it be a backup up rooted version of gb? Basically the same thing as the p3droid pre rooted gb ...

Not really.... It doesnt have the kernel update, the baseband update, or the radio update. Also, you can only flash it via CWR, not stock recovery.

adb pull is what I was trying to get him to do.

-reading about unyaffs it only pulls images.

If you want to turn everything into an update.zip, I still think your going to have to use AndroidSDK, and adb commands...(please correct me if im wrong)

[13th angel]

adb would have been easier ("adb pull /system" and your done) however he was asking about using a nandroid.... End up with the same result either way, just one way is more of a pain than the other.

Theres no time where you have to use the sdk/adb to turn something into a zip. Its the nice thing about using cwr, you dont have to sign zips so all you have to do is drop the files into an unzipped update.zip from a custom rom, edit the updater-script if needed and zip it then you can flash it.

Noob question- what is the updater-script? The screen during setup that tells you its extracting system, apps, etc?

So, if I replace the files in a update.zip or any rom in general, and rezip would somebody on 2.3.330 be able to flash my zip and be updated to rooted gb/cm7?
