Original Firmware Filestructure

The Firmware consists of many Parts
The PSI / SLB and UA have something to do with the booloader, because a other LG phone with the same chip has the same Filestructure

The Parts from an extracted Firmware like (not downloaded files)

The structure of the psi.flb from the Samsung is 99%the same!
It use the same CPU as the Arena

This are the Parts who can downloaded with Flashtool

ARM926EJ-S Memory Map

3.2 System Memory Map
This section summarizes the system boot settings and memory maps.
3.2.1 System Boot Settings
The boot method is selected by using the strap pins BRBOOTSEL,
VINITHI, and INITRAM. These three pins determine which device and
which address location the ARM926EJ-S processor uses. Possible boot
devices are the External SRAM, an external slave connected to the AHB
Slave Expansion Port using the Segmentation Bridge, or the Instruction
TCM, if the Processor System for ARM926EJ-S supports the use of
TCMs. Check the ARM926EJ-S processor datasheet.
