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.

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

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.

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.

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

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 🙂
