[Q] Can't get a zip signed with SignAPK
since several days now I try to sign a repacked update.zip to update with the normal recovery menu (not CWM) for my AM8726-MX Teclast tablet with Android 4.1.1 (ext4 filesystem). To track down the error I took a simple zip to root the tablet that works without problems from here: http://forum.xda-developers.com/show...0&postcount=36
The comment in the zipfile says: "signed by SignApk"
I unpacked the zip, deleted the CERT and MANIFEST files in the META-INF directory and packed the files into a new zipfile (WinRAR, 7-Zip, zip under Linux etc.)
I used signapk.jar with testkeys to sign the the new zipfile. The file has no zipfile comment. When I try flash the zip to my tablet in recovery mode ("apply update from EXT") it just says "Verifying update package..." and then "Installation aborted.". When I unpack the working signed zipfile and the one I repacked and signed myself and compare the single files they are all IDENTICAL. So far I tried:
- Different signapk.jar downloads (they seem all the same)
- Different java version (1.6, 1.7, Linux and Windows)
- Different Linux versions (32bit and 64bit)
- Different keys
- Different compression programs (WinRAR, 7-Zip, zip under linux)
I am running out of ideas so is there anybody who can give me a hint what is going wrong?
