[Update] CyanogenMod7 Android 2.3 Gingerbread with Market and Root on Archos 7 HTv2 (preview release)


Edit 2011/11/15: The firmware has been updated, please check release notes for details.

Thanks to the amazing work of  fun_ (aka naobsd) from www.androtab.info, the CyanogenMod7 (CM7) port for Rockchip RK2818 equipped devices, such as the Archos 7 HTv2 has reached a milestone. The system starts to be usable with the accelerated video now working, we felt the firmware is ready for a first public release. This release is still a proof of concept to show the development progress and for users to test Android 2.3 on their Archos 7 HTv2. If you do not want to risk serious troubles restoring your usual firmware after running this early firmware, we recommend that you wait a few days until a more finalized version is released.


This custom firmware brings Android 2.3.7 (Gingerbread) to your Archos 7 HT v2 tablet.
Additionnaly, you get other interesting features such as:
– root access
– Android Market thru ArcTools

Release notes

This custom firmware update is based on latest files from CM7 port by fun_
Release notes from the author (2011/11/15)

built with latest CM source. now 7.2.0-RC0.
“Screen-off animation” is disabled by default as workaround for “black screen on resume” issue. (if you changed this setting, please disable manually)
add initial support for hardware codecs. I’m not sure all supported codecs are enabled. please test & report about file URI, format detail, status, etc.

We modified the firmware so USB Host mode is disabled on boot.

Notes from previous release (2011/11/14)

it has “black screen on resume” issue so please disable “Screen-on/off animation” in CyanogenMod settings. (it may happen without USB… it happens when screen off but not in deep sleep)
EDIT: for now not well tested e.g. local file, other codecs, etc…

Please note that this firmware is valid only for Archos 7 HT v2 and will not work on Archos 7 HT v1. If you are not sure on which version you have, please check our Archos 7 HT v1/v2 page. If you have an Archos 7 HT v1 please visit our dedicated firmware page.

This custom firmware has no firmware update facility. You won’t be able to flash another firmware by copying an update.img file to the root of the device. You will have to use Rockchip Flashing tool to flash a new firmware, please make sure that you are able to use this flashing tool before flashing this custom firmware.

  1. bonjour
    petit probleme je n’ai rien qui apparait
    apres avoir copier le fichier dans le data de l’appareil celui-ci etant detecté comme un appareil mobil et non comme un disque dur fait a la facon archos pour copier à la racine
    j’ai meme eteint et relancer la tablette rien ne se passe

    je precise j’ai tablette archos 7c modele A70CHT

  2. Hey, installed it no problems, seems to work fine, but i calibrated the screen like a retard on acid assuming i can do it again later, but, well…. i cant. Cant select anything really, and now i cant boot from sd, any suggestions? i tried the reset button on back as originally doing this would reset calibration yadaa yadaa……

  3. Hi. I’m having problems installing the ArcTools. After installing this update firmware (Cyanogenmod-7.2.0-RC0-RK2818-KANG), I installed ArcTool , but i cannot download Google Apps because i get this message: “Error 25: file copy failed – Archive file cannot be accessed. please check that your device is not mounted on USB”. My device is not mounted (USB is disabled by this firmware, and the cable is disconnected…)

    Is there any workaround? If not – is there any other way i can download and install the Gmail application on the tablet? that is the main thing i want…

    • Work on firmwares for Archos 7HTv2 and Arnova G1 firmwares are a bit on hold these days, with focus on newer models running on Rockchip RK2918 CPU (Arnova G2 and Arnova G3). Hopefully some improvements can still be made on older firmwares, as time will permit.

  4. set itself this firmware first all seemed to work fine! but after I put the SD card and started watching movies, I noticed that the video slows down! decided to change back to its former firmware, but it did not work! using Rockchip Flashing tool did not work too well as on my windows 7 x86 is not possible to install the driver for this device (the driver is not designed to run on this platform) writes refusal. I pray help me the way I was told that there are some so-called alternative driver to work on windows 7! If you know anything please help!

    • Hi skarfer

      Try :
      – right clic on short cut “Rockchip Flashing tool”
      – clic on property
      – tab compatibility
      – Compatibility mode
      run this program => Windows XP

      My computer is in French, so I am not sure you will read exactly the same messages, but you will understand 😉

      I don’t try on this program but this solution runs well when the drivers were built to XP
      Good luck !

  5. A good job. I’d tested it on my old 7HTV2 and I prefer this firmware than others (Froyo or improvement Eclair). The only thing I missed is the configuration of my USB physical keyboard. How to configure my keyboard to definitively adopt cyanogen firmware ?

    • sfinxx1,
      The video is accelerated at the begining (when you see “10x time lapse” in the top right corner) during the firmware flashing and rebooting part which are quite long…
      The rest of the video plays at normal speed. Actually, the tablet is not that reactive, as there are many delays when touching the screen. This can probably be improved a little by tweaking the CM7 settings.

  6. does that works on zipy fun???
    i have one and i just want to “destroy” that ugly android version and quite limited…
    i have a simple problem with tv exit…
    (it’s built-in into sound exit and uses a simple video cable like any camera)
    i don’t know how to install it…
    can you help me???

    • Ismael Miguel,
      It’s hard to find the Zipy Fun specs on the web, appartently it is very similar to the
      Acorp EM501R which runs on a Rockchip CPU. First need to confirm it really uses a RK2818 CPU and not an older one. Then get the device firmware to extract the boot, kernel … to build a full firmware update with CM7.

    • To my knowledge there is currently no CM7 port for Arnova G2 models.
      Still, the G2 models running Android 2.3 Gingerbread, having CM7 is not a priority. Regarding the Android Market on the Arnova 7G2, it’s still in the works, will post an announce when ready.
