If you appreciate my work and would like to support me with a small donation you can click on button.
If every happy user of this rom would just donate a couple per month I could invest more time in all these Android projects, it'd cost you just like one coffee per month.

Instructions

* Unrar the "common" rar file and put "zt-update" folder to the root of a microsd.
* Put rom (cm-10.1-$DATE-UNOFFICIAL-c97.zip) and gapps (gapps-jb-$DATE-signed-ubifs.zip) files inside internal or external sdcard.
* Turn on the tablet keeping pressed VOL+ and POWER. Press VOL+ to confirm and you'll boot to CWM recovery.
* If this is your first install flash this file that will format /system, /data and /cache partitions and from "Wipe" menu erase "Android secure".
* Flash rom (cm-10.1-$DATE-UNOFFICIAL-c97.zip), gapps (gapps-jb-$DATE-signed-ubifs.zip) and, if you're using a different device, the required compatibility zip.
* Now select "Reboot system now".
* Enjoy CyanogenMod 10.1!

Changelog & download links

2013-05-18

* Updated upstream sources

Common 2013-03-03
ROM (md5sum)
Gapps 2013-03-01

Compatibility files for C93 H6 1F

Common 2013-03-03
Compatibility v1.1

Compatibility files for C93 H6 2F

TWRP recovery (create a folder named "zt-update" in your MicroSD and unzip there the recovery.img file; the bootloader will do the rest when you use the buttons trigger combination)
Compatibility v1.1

Note that if you're running the latest C93 stock firmware "ZT283_H6_2f_1GB_Android4.1_0202_V1.6" you will have to use this TWRP and this comp zip.
If you accidentaly used the previous files you'll see that partition's got fucked up and you'll have to flash the stock firmware to fix them

Issues

* Use another launcher (I suggest you "Nova" or "Apex") because Trebuchet screws the layout.
* Bluetooth stack has changed: USB bluetooth is not working right now; only devices with UART (internal) bluetooth works.
* If your device has only a front camera you won't have a camera launcher icon, but you can install this app

FAQs

* If you don't like Nexus 7 fingerprint and wanna use SGS-II instead flash this zip. Remember that changing fingerprint may screw Play Store, if it happens you'll have to perform a "wipe data / factory reset".
* WiFi now can stay enabled with display turned off. Note that if WiFi is enabled the tablet won't enter deep sleep so if you're more interestead in battery life instead of an always on WiFi change policy (on "Advanced" WiFi settings) from "Always" to "Never".
* Internal memory is mounted at /storage/sdcard0, external sdcard is mounted at /storage/sdcard1. If you wanna swap them (and make primary your real microsd) just flash this file after flashing rom's zip (you have to do it everytime you flash a new version of the rom)
* If you wanna format your internal memory (it's corrupted, filled of crap, etc.) just flash this file from recovery. If it fails try to unmount internal storage from "Mount" section.
* It's better if you don't change governor because the included "ondemand" has been customized to support "boostpulse" feature of jelly bean power hal. You can control min/max cpu frequency with display on/off editing these entries in /system/build.prop file (they're listed with their default value): "ro.sys.min_cpu_on=408000", "ro.sys.max_cpu_on=1200000", "ro.sys.min_cpu_off=96000", "ro.sys.max_cpu_off=1008000".

Hi.
I still got the same problem even after changing the heap size:

Error (Airplay v4.3.0 [250761])
Heap 0 out of memory. Allocating 3145728 bytes but only 3971808 available (1398132 LFB).
Increase icf setting [s3e] MemSize (currant value is 30000000).

The common file is supposed to be unrared, and the zt-update folder put onto your (FAT32) sdcard... And the compatibility file is supposed to be flashed last....

Maybe I need to increase my app cache size. Any idea how to do this?

You can't without altering partition table in the kernel. You can symlink a folder in /data to /cache anyway.
Try these commands as root

su
umount /cache
mkdir /data/newcache
chown system.system /data/newcache
mount -o bind /data/newcache /cache

If it works it can be executed at boot easily

A static sound can be heard when it's in standby,something similar to a fart. It may be a problem of the audio DSP, it doesn't happen on the c93 that uses a Wolfson chip for example

It's a constant hiss, standby or not, and sometimes it reminds me of the electronic noise you can get if your headphones are plugged in to your computer and the hard drive is working on something, you can hear an electronic interference sort of noise. It's like that except loud, through the speakers.

I don't know if it's related, but the Sound Recorder dies every time I try to use it - click Done and it says Unfortunately Sound Recorder has stopped working. It saves the file but the quality is absolutely rubbish, you can hardly hear anything. Other files seem to play okay, so the sound output is working.

Sorry to be a pain about this, I would like to use CM10.1 but the reason I got this tablet was to use it for music (as in, for my sheet music, chord sheets, for performing music, not just listening to music!
), and this noise is easily audible in a normal room with road noise, fan running, etc. In a quiet studio or near a microphone it would be unacceptable. Is there anything I can try? I could record the noise so you know what I'm talking about I suppose, but would that help?

Hello I have a question. Id like to change my CM10 rom because sometimes the device reboot without a reason. I'd like to try this new rom CM 10.1 but I need to use the bluetooth USB for many reasons (BT GPS, wiimote controller etc...), but i saw that in this new rom it isn't supported. Which rom can you suggest me? thank you in advance

You don't have much of a choice, if it wasn't for me c93/c97 would be totally unsupported

sorry for my insistence! "only devices with UART (internal) bluetooth works." Is there any c93 with internal BT? How can I know if my device has got it?

I unzipped the zt-update folder, and added the common and gapps zip folders to the sd card, then shut the tablet off. I then Restart it while holding Power and pressing or holding volume + and when it turns on it flashes

Volume + Pressed
prepare enter mcc update mode
hw testing started...
skip recovery

Then it reboots like nothing happened

I have also tried holding the power and back back button at the same time, this brings up a totally different screen

Then it enters a Camera + mode

Then says the following

Found 'LK:ZT283_I1_2a', dismatch 'LK:ZT283_H6_1F'
do *kernel update? 'CAMERA+' key sure, otherwise cancel

I then hit camera + and the message appears again

Found 'LK:ZT283_I1_2a', dismatch 'LK:ZT283_H6_1F'
do *kernel update? 'CAMERA+' key sure, otherwise cancel

i then hit + again, and then it updates

I then go to my tablet info section, and it does not show that cm10 is installed.

Why I am doing this is I have only had this tablet for 2-3 weeks, and about a week and a half ago i suddenly lost access to 5.7gb of my internal storage. I was only able to access the 881mb. Somehow the 5.7gb of internal memory got unmounted. This also stopped me from mounting any external sd cards. All of my apps that were linked to the internal memory that was unmounted were no longer accessable. I then downloaded the ICS C93 Mod off of slatedroid and restored it. This fixed my problem.
Well yesterday this happened again, So I restored it again with the same update, and currently the tablet is back to normal, just like when I bought it.
What I would like to do now is to Put Cm10 on it or root it where I can download and use a Partion app, where I can manage my own partitions without. Or does anyone know why my device is doing this and how to fix it?

Volume+Power is for the C97, Back+Power is for the C93's... If it is saying Found 'LK:ZT283_I1_2a', dismatch 'LK:ZT283_H6_1F', it means you have a C93 and are trying to flash C97 files onto your tablet... You are supposed to use/unrar the common file for the C93 (that has the zt-update folder in it) and be flashing the C93 compatability zip file last via CWM/TWRP recovery (first ROM zip, then Gapps zip, then C93 compatability zip)....

Hi!

I've a C93 and I had the same problem "skip recovery". I was flashing the C93 with a FAT32 16GB SD Card (that didn't work at all... with a stock ROM or Custom ROM).

I changed to a FAT32 4GB and worked stock ROM and Custom ROM every time I tried.

I hope that helped you!

-by the way For the C93 the compatability should be flash last-

Is the rebuilt kernel you made for the C93 now rolled in ? My tablet's been running a lot better since making that update.
Thanks for your work.

No on c97/93 you can't flash boot images, you have to let the boot loader flash them and unless you replace the .kernel file in zt-update folder it won't change

Any reason not to put that rebuilt kernel in the C93 common file instead of as a separate download. I haven't had any of the (seemingly) random system crashes since installing it.

Hi. Even though I have installed the camera patch, the image is still upside down on the front camera in portrait view. Landscape is good though. How can I fix this? Thanks for your help!
