What you do is this, load ka ng 500. Text mo yun lto 2600.
Start from ADK-198 then ADK-298 etc. Hanggang makarating ka ng ZDK-998
Pero since sa Q. Ave, baka taga dito lang yun. So kung old model, most likely PDK, TDK, or UDK.
But the problem is, even may magmatch sa description mo, you cant be entirely sure na same yun sa nakabangga sayo. Kawawa naman if you put the blame on someone thats entirely innocent.
