Upcoming Community Efforts

• PostmarketOS port for MT5510 (kernel 5.4 mainlining).
• Dump of PB803's OEM service manual (includes pinouts for JTAG and UART).
• Alternative firmware using Yocto Project (embedded Linux without Android).

If you depend on this device for business, consider buying spare mainboards from AliExpress (search "PB803 motherboard MT5510") and keep at least two copies of the firmware on different storage media.

Q3: Is there any custom ROM like LineageOS for this firmware?

Rarely. The MT5510 lacks open-source GPU blobs (Mali-400 MP2). However, some Russian developers have posted LineageOS 14.1 (Android 7.1) builds for mt5510s boards on 4PDA. Search for "MT5510 LineageOS 14.1 PB803."
