BEY → Build date code.

B = Year (2024).

E = Month (May).

Y = Build revision within that month.

G1 → Software version / revision number.

So A146PZHSBEYG1 decodes to: Galaxy A14 5G firmware, region ZHS, built May 2024, revision Y, release G1.

Sample2: ID G998USQU4AUG4:

• G998U → Device model (Galaxy S21 Ultra 5G, US unlocked/carrier model).
• SQU4→ Series and bootloader version.
  • SQ = Samsung’s code for the firmware series.
  • U4 = Bootloader version 4 (important: you cannot downgrade below this).
• AUG4→ Build date code.
  • A = Year 2021 (Samsung cycles letters for years).
  • U = Month July (letters A–L = Jan–Dec, but Samsung skips some letters).
  • G4 = Specific revision of that month’s build.

YEAR Code

• A = 2021
• B = 2022
• C = 2023
• D = 2024
• E = 2025

Month Code:

• A = January
• B = February
• C = March
• D = April
• E = May
• F = June
• G = July
• H = August
• J = September
• K = October
• L = November
• M = December

How to know binary value in Samsung firmware
sample:

• G998USQU4AUG4 → Binary 4
• A146PZHSU3AWF2 → Binary 3
• N975FXXU9HWI1 → Binary 9

Note:

• You cannot downgrade to a lower binary.
  • If your phone is on Binary 4, you can only flash Binary 4 or higher.
  • Trying to flash lower will fail in Odin with a bootloader error.
