Instructions to install the Qbox-receiver v2.x firmware

Part 2 — Installing the custom bootloader — Breed

Warning/Disclaimer: there is a risk of damaging your device internal configuration if something goes wrong during the process. Proceed with absolute care if you don’t know what you’re doing. I deny any responsibility for any kind of damage caused to your router or to you.

1. Now I assume that you have access to your router console/telnet, so log in to the router firing up your linux console (or putty on windows)

telnet 192.168.31.1

2. this is the risky part, proceed with extreme caution as a broken bootloader could brick your router, the only way for you to revive the router would be to physically wire a serial cable to rewrite the bootloader;
4. download Breed for Xiaomi router mini here;
5. copy it to the root directory of a usb thumb drive (1GB free space is more than enough) with FAT/FAT32 partition;
6. plug the thumb drive into the router;
7. on the console connected via SSH to the router, type

cd /extdisks/sda1/

followed by

ls -l

you should be able to see the breed-mt7620-xiaomi-mini.bin file;
8. type

cat /proc/mtd

it will list out the partitions on the router flash chip;
9. look for “Bootloader”, it should be listed as mtd1: 00030000 00010000 “Bootloader”;
10. now dump a backup of the partition to your usb drive with the following command

dd if=/dev/mtd1 of=/extdisks/sda1/Bootloader.bin

11. you should also create a backup for all the other partitions listed by

cat /proc/mtd

you will see a list of blocks with a block index (e.g. mtd1) and the block’s name (e.g. Bootloader). Adjust the command above replacing the highlighted parts with their respective block index and name.

dd if=/dev/mtd1 of=/extdisks/sda1/Bootloader.bin

All of the backup files will be in the usb drive;

12. now you’re ready to install the custom bootloader, type

mtd -r write breed-mt7620-xiaomi-mini.bin Bootloader

13. it should show rebooting when the installation is complete.

Part 3 — Boot into Breed, install the QBox receiver v2.x (Padavan firmware)

1. download the firmware from airplaycar download page here, you will get QBOX-MI-MINI_3.4.3.9-099.trx file after extraction;
2. power off your router, look for a pinhole on the back, power on your router while pressing and holding the button inside the pinhole;
3. release the pinhole button when you see the orange/yellow light blinking;
4. open your browser (preferably Chrome) and type 192.168.1.1 into the address bar;
7. you should be able to access the Breed web interface (in chinese but I will guide you!);
8. now select the second button on the menu;
9. now you should be located at http://192.168.1.1/upgrade.html, select the custom QBOX-MI-MINI_3.4.3.9-099.trx firmware file on the second row of the form. Then press the last button on the bottom of the form. It should look like this

10. wait for the progress bar to complete, it should reboot automatically;
11. you might need to boot into Breed for the second time to reset the default settings for the Padavan firmware. To reset the settings, click the 5th button on the menu, then select Config and click the submit button to reset the settings. It should look like this
