@Thenorthernsea You can create your index file for QC earbuds once you have the version string. For me, I first found 1.0.7 is 1.0.7-xxxxx+620b71c, so I try to create the download URL from current version 2.0.7. Here is my steps:

Download the bin file

From official index.html:

<INDEX REVISION="01.00.00">
<DEVICE ID="0x402F" PRODUCTNAME="Quietcomfort Earbuds" USE_CLOUD="0">
<HARDWARE REVISION="01.00.00">
<RELEASE HTTPHOST="www.bose.cn" LANGUAGES="en-us,es-mx,de,it,fr,zh-cn,nl,ja,pt-br,ru,pl" REVISION="2.0.7-fb87694" URLPATH="/ced/bose_music_china/lando/">
<IMAGE CRC="0xFCFF86A2" FILENAME="lando_2x1_rom_spin_encrypted_prod_2.0.7-fb87694.bin" LENGTH="6350682" NOFORCE="1" REVISION="2.0.7-fb87694" SUBID="0"/>
</RELEASE>
</HARDWARE>
</DEVICE>
</INDEX>

So I guess the 2.0.7 bin is , it did work: https://www.bose.cn/ced/bose_music_china/lando/lando_2x1_rom_spin_encrypted_prod_2.0.7-fb87694.bin

Then I replace the 1.0.7 string, the URL works too: https://www.bose.cn/ced/bose_music_china/lando/lando_2x1_rom_spin_encrypted_prod_1.0.7-620b71c.bin

Get the CRC and length

Once bin file is downloaded, file length and CRC value will be calucated:

# Get file length
ls -l lando_2x1_rom_spin_encrypted_prod_1.0.7-620b71c.bin
-rw-r--r--@ 1 root  root  6341544 Nov 16 19:07 lando_2x1_rom_spin_encrypted_prod_1.0.7-620b71c.bin

# Get file CRC

I tried. the log says "update failed". however the 1.0.7 firmware can be installed.

I found there is a error in the official index , the length of the 2.07 firmware is 6534306, but the index shows it 6350682 as it is the length of 1.27. So that is why it does't work.

The info you provided is very helpful! Now it can be updated. By the way, the original CRC value is also incorrect.
