Update 5-29

New version without much advances, almost all are helping programs and some little changes.

New menu for HDMI resolution
Added the chinese galery apk
Added AllwinnerMod for Gameloft Games (select Xoom)
Added Nemus Launcher if you have problems with Trebuchet (default launcher). In first boot you must select which launcher will be used, but can be changed in settings/applications.
Added Hackers Keyboard.

This update is installed like allways, full wipe included… I hope this will be the last one with a full wipe. necesario.

If the tablet stalls, please reboot it (full shutdown) before complaining…

If you like to have a 1.2, but you will not use the HDMI menu, all the apps are in the market and are free… (but the chinese one).

Hi…

This is a CM9 porting for GemeiG9 and clones, it may work in other tablets but i can help you with this.

Install steps:

1) Install CWM using this http://www.slatedroid.com/topic/32200-cwm-installer-and-apk-for-momo11gemei-g9/ or installing PPORomv1.1 (search in google)
2) Start CWM using button volume – with power or novotools
2) Wipe (it will delete all your data, so do a backup)
3) Update using the zip downloaded

First time last almost 10 minutes, so be patient… next boots will be fast. If it stalls at firts boot (screen freezes) shutdown and restart using power button.

All the hardware is working (volume buttons are switched, – is + and + is -). Wifi is far best that default rom and some othe tweaks. Flash video is falty..😦. CPU speed is 1200Mhz, if you have problem with games or google play (they force close or only close without any message) download from market Antutu CPU Master or similar app and downclock the cpu to 960Mhz. The speed will be almost the same, but all will work.

USB Bluetooth, tested with a conceptronic dongle, may work with others.
USB GPS: Use this http://bit.ly/KFMgkR and this http://bit.ly/JFuJqH. Install Serial Port, start it and use as device /dev/ttyUSB0 (if this device is not show, your device is not compatible or not connected). You might also change the bitrate so in the console button the text is clear and not symbols. Once done, start internalGPS and select device, press start and you get GPS data.

To install google apps download this http://goo.im/gapps/gapps-ics-20120317-signed.zip and update with CWM.

  1. Touchscreen is not working with this latest firmware on my Gemei G9 black back cover😦

    • Could you send me the output of dmesg?

      Open terminal emulator, and exec

      su
      dmesg > /mnt/sdcard/dmesg.txt

      You will have a dmesg.txt file in your sdcard… upload it somewhere and send me the link.

      Corvus.

    Thanks….^^

    • Is a missing line in a init file…

      Easy to fix.

      Open Terminal Emulator and write:


      su
      nano /system/etc/init.d/02modules

      With this you can edit this file.

      Add this line:


      insmod /system/lib/modules/mma7660.ko

      Save the file and reboot.

      This may work. If not contact me again and i will try to fix it…

    Thank you very much for you work. I’m looking for the “screen adaption” option in setting, it’s not there in your firmware, but it’s available in the stock firmware, some games need that option to play, can you help?

    • No, sorry… we dont have this sources to add them… anyway what games are not working?

    Hi Corvus, thanks for the good work that you are doing with CM9. I have been unable to get my screen to work. I have loaded latest CM9, GAAPS
    but touch screen does not work. I tried three different G9 Comptability files and when flashed my tablet does not boot. It gets stuck on Gemei boot logo screen.

    • Compatibility files are not compatible with this rom, only with Christian Troy one.

      I can fix yout touchscreen, but need that you send me a dmesg output like explained some comments away.

      If you cant enter, you can use adb shell, search in google for more info.

      Corvus.

    hi corvus..first of all …very very compliment to this rom.

    i tried to download from your links but unfortunately it’s doesn’t work….
    at now i have installed into my g9 this rom

    G9_A4.0.3_V4.15-2GB_CHS-456_Overclock Ram speed

    you know if cm9 is better?

    thank you in advance federico

    (you are Spanish guy?? have luck for this evening for Spain Vs Italy European cup😛 )

    • Yes, server is down… working on it.

      About this version it may work as good as CM9, but some tweaks are only in CM9 and will not work in chinese version.

      Yes, i’m spanish… hope we have a good match😀

    Hi, Corvus! Thank you for your work!
    I flashed version 5-29 + gapps and flash video fix. Everything seems to work pretty fine, but I have same problem as was on original gemei’s ROMs: I can not start device without power supply (for some reason it worked couple of times once I flashed it, but since then – now progress – circle is rolling endlessly). Once power supply is inserted, device boots rather fast (about minute), but reboots till AnTuTu CPU speed succeeds to reduce CPU to 960. I think that boot problem is in default CPU frequency set to 1200 as my device works stable just on 960, on higher frequency apps are crashing and reboots happen. How is it possible to set frequency to 960 as default speed, so that it works already before system starts? Could you please create version with downclocked to 960 CPU speed.

    TIA

    • Soon a new rom with all this things fixed… no ETA, sorry…

        Thank for the update! Will wait for fixes that make my brick an iPad😉
        I have strange thing with your ROM: first days it worked fine, but later start rebooting (on 960 MHz), freezing etc and stops booting even with power supply. I boot to CWM, make a backup, reset all data, restore backup and device again works fine for several days… And later again stops booting…

    hi corvus and thank you for your effort to this rom.

    i bought an Gemei G9 used with CM9 allready installed.
    my problem (exept some reboots and crashes) are 2.

    i get “not digital signed application’ on all market. i have installed superuser fix but allthou it says all ok, problem stays.

    the second one and worst is that CM9 doent see the 16GB.
    when i do factory reset, after boot up memory is visible. after a couple of minutes it automaticly reboots and upgrade CM9. after the upgrade 16gb are gone and i get “sd card damage, reformat”. of course format does nothing….

    any suggestions?

    thank you in advance miltos

    • About market problem…. is common, and my opinion is that the wifi is so weak that it doenst download correctly the apks. Try to get more signal and retry…

      About sdcard, sorry… noone has this problem, so i cant reproduce it.

      Corvus

  6. Thanks for the information which will help me a lot.
