Notes / Warnings

• Compatibility varies by phone (some Android versions or manufacturers have USB host issues).
• Many of the classic ComboTool APKs are old; test carefully and scan files.
• Voltage: Most CH341A boards are 3.3 V / 5 V switchable — set correctly for your chip (most modern SPI flash is 3.3 V).
• For serious BIOS work, many people still prefer a PC with AsProgrammer / NeoProgrammer / CH341A Programmer Windows tools.
