How to Upgrade Firmware for CX-01 mini PC

[WARNING: Although these instructions worked with my hardware (CX-01 bought via Pandawill), it appears to break some CX-01 devices (See comments section), so use these instructions with care]

Pandawill finally managed to release CX-01 firmware (234 MB) about a week ago. This firmware can be used for devices with 4 or 8 GB flash memory (2 separate directories). You only need to update the firmware if your device has some serious problems, or if CX-01 gets a proper firmware update (we can always dream…).

Once you’ve downloaded ROM for android TV CX-01.rar in a Windows PC, extract it and enter ROM for android TV CX-01 directory. You’ll find 1 file and 1 directory:

  • V1.0-4096-8189_en – Directory for 4GB firmware
  • V1.0-8192-8189_en – Directory for 8GB firmware
  • FWDN_8923.zip – Telechips tools to burn the firmware to flash

Extract FWDN_8923.zip, go to vtcdrv directory and install the driver corresponding to your operating system.

Now click on FWDN_V7_v2.22.exe, click on , and select one of the 3 files in V1.0-4096-8189_en then click on add file. Repeat until you’ve added the 3 files for the 4GB firmware:

  • CX1-V1.0-4096-8189_en.rom – MTD
  • lk.rom – BOOT
  • NAND Data.fai – NAND Data

Now connect the mini USB to USB cable to your computer (but not to the CX-01 just yet), press the Fn key and insert the mini USB cable into the CX-01, until it is detected by Windows and complete the driver installation. Once this is done, the Area Map section you show the NAND Data and MTD partitions. Click on the Start button to start flashing the new firmware to the device.

Once you see “Download is complete! (1st)” the update is complete. This is the log for the update:

This method should also work for other Telechips device by simply using the corresponding firmware files and most likely a slightly different way to enter flash mode.

    Did you notice some improvements, like WIFI working properly or shutdown button added?

  2. August 17th, 2012 at 20:40 | #2

    I did not noticed any Wi-Fi improvement, and they did not add a shutdown button. However, I haven’t come across the 100% CPU usage bug, maybe I haven’t used it long enough.

    So where is the changelog?

  4. August 18th, 2012 at 10:08 | #4

    This is the only firmware release, so no Changelog. The build date has only 6 or 7 day difference with the firmware installed in my stick, so it’s just to use in case something goes wrong.

    I bought 15 of the android 4.0.4 tcc8925 aliexpress to sell on eBay. Fixed theplaystore problem, but all games stop. Will this firmware help if I re-flash.
    Also noticed a typo
    V1.0-4096-8189_en – Directory for 4GB firmware
    V1.0-8192-8189_en – Directory for 4GB (8GB??) firmware

  6. August 18th, 2012 at 15:19 | #6

    I’m not sure as I’ve never had problems with the play store using the original firmware. I don’t usually play games on Android mini-PC as the games I prefer require a G-sensor. Which games did you try?

    August 18th, 2012 at 17:56 | #7

    As you probably guessed I am an android noob so forgive me if I come across like a bit of an idiot…learning on the job. The playstore would stop after every download, upgraded the binary that worked. Gave to my son, he is 10 likes games like bakery story and nightclub story. Both of which stop. Dunno how to debug. Any ideas. Might do a vid later to show prob.

    Hi guys I was wondering if you could. Enable the uinput in the kernell and release to us the input.ko so we can use the droidmote.

    Also it will be an excelent idea if you could release a tweaked version of the kernelk with all the basic stuf that should be good in a kernell fir a eevice like us.

    Thank you very much.

  9. August 19th, 2012 at 22:11 | #9

    I suppose I could try to build input.ko, but what extra do you need in the kernel? And where would you copy the kernel in the device?

  10. groovey2k
    August 20th, 2012 at 02:31 | #10

    In the config file for the open source kernel uinput seems to be enabled (it says something like uinput=y somewhere). So maybe it would work if we could just flash the kernel.

    I’ve tried Nightly club story and it can run, although not especially smoothly.
    If your son can play the game for a while, and suddenly it appears as if it hanged, it’s probably because of the 100% CPU usage bug. If it just stops and goes back to the home screen, it might be a memory usage issue, as the game does not appear to be really lightweight. One way to mitigate this memory issue, could be to run Advanced Task Killer to kill all other tasks before running this game.

    What’s the problem ?

    Same has happened to me. Stops at CRC check … also bricked

  17. September 11th, 2012 at 23:36 | #17

    I used CX-01 I bouht via Pandawill and used the flash tools in Windows XP.
    Have you guys also bought the device with Pandawill? I wonder if there are different hardware revisions.

    September 12th, 2012 at 00:32 | #18

    Didn’t buy from Pandawill but had previously rooted it and installed Tatubius’ tweak via windows xp without difficulty. Interestingly when I tried to reflash with original firmware it tells me the NAND Data files sizes are different, records an error and stops download.

    Bought mine from Digimate in the UK. Hung after the progress bar went to 100% in CRC check. Had to end task. Bricked. I had the same message about NAND sizes as jt

    can i install cx-01 firmare in z900.

  23. September 18th, 2012 at 18:06 | #23

    I don’t recommend it, you may brick your device and there is probably very little improvement over the version you have. If you want to upgrade anyway, do NOT load lk.rom, and make sure you backup your system partition. If you don’t know how to do those steps, then don’t do it, you’re likely to render your Z900 unusable.

    Zero Devices should really provide a firmware update, since they promote themselves as a brand, and as such should have better customer support than other noname manufacturers.

    Followed the steps in the link with the 4Gb custom ROM and it didn’t work – used the 8Gb custom ROM and it passed the CRC check! Thanks 🙂

    my problem is the wifi range is very short

  28. November 4th, 2012 at 23:12 | #28

    Yes, that’s a problem for everybody, and no firmware will fix this. There are some tricks to improve the antenna, such as inserting a copper coin.

    where is nand data?
    i can`t find it

  30. November 6th, 2012 at 19:16 | #30

    If I remember correctly it’s only in the 4GB firmware, the 8GB firmware does not have this file, but it’s not important, you don’t really need it.

    how long to”single download”?

  32. November 6th, 2012 at 20:01 | #32

    I think it takes around 10 minutes to flash the firmware.

  33. chue
    November 6th, 2012 at 20:29 | #33

    maybe can`t support 8G stick?anyone success update firmware to 8g stick?

    Same thing happened to me, but I was able to flash the 8GB version of the rom wiithout problem despite the fact that CX-01 has a 4GB label on it.
