I've just installed custom firmware........ (c91 upgrade)

[benadlam]

From here

[ROM] - Android ICS 4.0.3 Light Edition 1.2 - C91 upgrade H3 - 1A - SlateDroid.com

and it seems far better than the Zenithink official!

Great, but tell your C91 model, cause its important. This ROM is for 1A

lol, you know. I never actually paid any attention to that! I just flashed it! I assume mine is a 1A. How do I actually check? I just figured if it didn't work I'd flash the standard back. But it noticeably faster! I definitely am happy with it!

 

[benadlam]

Just updated the Kernel too so it's overclocked to 1.2Ghz.

It's like a different machine!

 

[gmajnkek]

On the side its writen whats your model. Mine is 1A

 

[benadlam]

Yea its 1A

Where is the install files located? This install over the USB?

 

[benadlam]

ZT282V327light3ditionv1.3.2.rar

And just update like a normal zenithink update. Copy all the files into the zt update folder (like it says on zenithink website)

 

[stevohaker]

Is this version 1.2 in french or it can be in english or any other language?

 

[benadlam]

Its any, I'm in England, because it re flashs it runs through set up wizard so you pick language etc again

once you flash that rom, if you then flash a 1.2 kernel the tablet is just awesome!

 

[gmajnkek]

Well using the 900MHz kernel cause no need to have more at the time. its just awsome. Faster, smoother...

 

[benadlam]

Have you done a test with that quadrant standard app?

Do there appear to be any drawbacks to using this rom? The official rom upgraded for me without losing data or programs.

I honestly couldn't tell you which C91 I have. All the relevant data I have on my tablet is down below. I think this C91 is a model number 2N.

Thanks so very much for your help. I'd really like to install this if it would work for me. It looks super.

I am having a C91. From yesterday I am getting "start kernel error" on booting the tablet. I am trying to upgrade the firmware [Zenithink]. I have formatted SD card and put the zt-update in root. On starting the tablet with camera + start button, it shows mmc update mode and system update starting. After that screen goes blank and no updates on screen. Do this mean that still firmware update is happening or something is wrong? Screen is powered on but showing no logs..

You have to download the latest custom rom software, download the kernel for the 1n separately and swap it in. And replace the custom roms recovery for the stock Zenithink...... Which is easy enough actually!
