Hollyland Lark M2 firmware update

• Charging case firmware V2.0.0.32 (25 Mar 2024): fixes known issues.
• Hollyland does not publish version numbers for the transmitters and receiver: they update through Hollyland's phone app or the LARK M2 Upgrade program on a computer.

Transmitters and receiver (phone app):

1. Charge everything first, and update every transmitter, the receiver and the charging case.
2. Plug the receiver into your phone and open Hollyland's app (LARKSOUND in Hollyland's guide, listed as HollyAudio on the download page).
3. When the app finds a new version, tap the Upgrade icon at the top right, then Confirm. The lights turn pink and purple during the update.

Charging case (computer): connect the case to a computer with a USB-C cable, copy the file 6301Box.bin to the case's drive and leave the cable connected. The four lights go off for 5 seconds and then light up in turn; when the file has gone from the drive, the update worked.

Hollyland advises not to update right before an important event.
