PL/LK log formatter

pllk_log_formatter is a console (command-line) utility that formats PL (preloader) and LK (Little Kernel) logs produced by fastboot client utility with "oem dump_pllk_log" parameters.

fastboot utility supports Android devices only. The support of "oem dump_pllk_log" parameters depends on device's firmware.

fastboot utlity retrieves log data in short chunks, and precedes each chunk with "(bootloader)" prefix, so the output is very hard to read and analyze. This format utility removes the prefixes and concatenates the chunks together.

PL/LK logs retrieved in fastboot mode are associated with current boot session ending with fastboot mode/protocol server. Therefore, these logs may not be suitable for investigating hangup/bootloop problems, because the logs from previous unsuccessful session(s) are usually overwritten by most recent logs from the current fastboot session. In such cases, manufacturer-specific tools may be needed to extract the contents of the log partition using special lowest-level protocols.

In any case, the logs obtained with fastboot utility may be useful in researching the device's operation. The logs usually contain information about internal hardware identifiers, preloader/kernel configuration, flash memory partitions, etc.

Works in Windows 2000, XP, 2003, Vista, Windows 7/8/10/11, on x86/x64/ARM64 platforms.
