Hello,
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/showpost.php?p=41759110&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?

Thanks, HellG.

I found a newer version of the signapk.jar that works. I searched for the zip comment "signed by SignApk" and found it in the newer version on git and here: http://www.android-hilfe.de/attachm...d1338829904-meine-rom-update-zip-packager.zip

What command did you use to get the comment? I'm using those files and I still don't get it, and further, trying to unzip it in TWRP commandline gives me "unzip: zip flags 1 and 8 are not supported" where an unsigned zip does not.. :(:confused:
