There is no Jelly Bean ROM for the ZT-280's or ZT-282's...
The last official ICS ROM for the ZT-280 C91 H1_2n is the 0314 ICS 4.0.3 ROM....

You may be interested in trying Pas's altered ICS ROM - [ROM] ZeniBasic ICS v1.2 28/02/2013 - SlateDroid.com (Remove the ZT282.* files from the zt-update folder and remember to move the files and folder from the ZT-280 C91_2n folder into the zt-update folder... I have not tried this ROM as I think Gingerbread is more stable and uses the 512MB RAM more efficiently.)
http://www.zenithink.com/UploadFile/temp/ZT280_H1_2n_C91_Android2.3_0217_GO_V1.35.rarMay i know the Gingerbread rom you mention above, where can i download? i bought the tablet of 2n version. I also think that Gingerbread more stable, but can't find any source to download. Help.

You need to use the zt-update folder that's in there and add the files/folders from the 2n folder into that one, then copy that zt-update folder onto your sdcard.....omarahum - I d/l the rar file, unzipped, and still don't know what files in that file to put in the zt-update folder. There are 23 files in the rar file, and the Readme.text file says "If you C91 type is 2n, please copy these 4 files in the folder "2n' to zt-update directore". The problem is that it doesn't identify which 4 of the 23 files I should put in the zt-update folder.
Here is the data on my ZT280:
(From Sticker)
Model – ZT280H12NC91M512F8
Serial Number – SD1111161101N******
(From Device)
Model: ZT280
Android Version: android 2.3.4
Kernel Version: 2.6.34 root@android #2483
Build Number: b01ref-eng 2.3.4 GB.b01ref.2011094 eng.root.20110924.132957 test-keys
You need to use the zt-update folder that's in there and add the files/folders from the 2n folder into that one, then copy that zt-update folder onto your sdcard.....
So in the zt-update folder you should have:
media - folder with version.txt in it, file is copied to the media partition...
command - tells the recovery what to do
data.zt280.tar.bz - files for the data partition
media.zt280.tar.bz - files for the media partition
system.patch.zt280.tar.bz - small patch of files for the system partition
system.zt280.tar.bz - main files for the system partition
ZT280.kernel - kernel used when your tablet normally boots up
ZT280.recovery - kernel/recovery used when you boot into flash mode to flash your tablet
ZT280_H1_2n_C91_Android4.0_0313_V2.8.txt - Really not needed, just tells you what ROM the files in this zt-update folder are from...
Strange, the rar file should look like thisThere is no "zt-update" folder in that file.
Here is what I tried.
Full FAT32 format on a 16gb micro sd card.
1. made a "zt-upgrade" folder on the sd card.
2. made a "media" folder on the sd card and copied the version.txt file into that.
3. copied the other files into the zt-upgrade folder on the sd card.
My "zt-update" folder on the sd card looks like this:
media\version.txt (this is the media folder with the .txt file in it)
command
data.zt280.tar.bz
media.zt280.tar.bz
system.patch.zt280.tar.bz
system.zt280.tar.bz
ZT280.kernel
ZT280.recovery
After the camera/power on, I get:
"camera key pressed"
"prepare to enter mmc update mode”
“system update start...”
“do not touch screen, recovery will do a calibration”
"skip recovery"
"kernel start"
“green droid”
and then a blank screen
Now what? Or do I now have a neat looking paperweight
