How to find out the Firmware, Serial Number, Bootrom of your iPhone

IPhone serial number - serial number decryption


Any iPhone that’s sold in the store comes off the assembly line of the Foxconn factory or is already in operation, equipped with a 11-character serial number . The serial can be seen on the phone box or in the information about the iPhone device ( Settings - General - About the device ). At first glance, the usual character set, but not everything is as simple as it seems at first glance. In fact, the letters and numbers of the serial number carry information that can sometimes be useful - the phone’s release date, color, memory size, iPhone model and even the factory on which the device was made. This data may be needed to identify the iPhone model and to verify the authenticity of the device.

In addition to numbers, there are letters in the iPhone serial number, so do not confuse it with the unique international mobile IMEI identifier containing only numbers. The characters of the serial number are permanent, that is, they have not changed since the phone was made, but if the iPhone was in the repair of the official service, then Apple changes the first characters of the serial.

As an example, consider the serial number - 82034 *** A4T and try to decipher its values. All iPhone serial numbers are in the following format: AA B CC DDD EE F

Where:

  • AA - ID of the factory in which the iPhone was made
  • B - Year of manufacture (the number - 0 means that the phone was released in 2010 or 2020, if in our case there would be a number 9, then the year would be 2009 or 2019, etc.)
  • CC - Production Week (34th week or August month)
  • DDD - Unique identifier
  • EE - Color (A4 = black)
  • F - Memory Capacity (T = 32GB)
Bootrom iPhone - Bootrom decryption

For example, the iPhone 3GS: 88929PG33NP where ** 929 ****** is the year 2009 and 29 weeks of production. 3gs made before the 45th week of 2009 usually have an old bootrom, between 40-45 a week - the results vary, after 45 - a new bootrom.

Using the last 3 characters of the serial number, you can independently determine the model, color and memory size of the device, this will help the list of possible iPhone models:

  • VR0 - iPhone (2G) 4 GB
  • WH8 - iPhone (2G) 8 GB
  • 0KH - iPhone (2G) 16 GB
  • Y7H - iPhone 3G Black 8 GB
  • Y7K - iPhone 3G Black 16 GB
  • 3NP - iPhone 3GS Black 16 GB
  • 3NR - iPhone 3GS Black 32 GB
  • 3NQ - iPhone 3Gs White 16 GB
  • 3NS - iPhone 3Gs White 32 GB
  • A4S - iPhone 4 Black 16 GB
  • A4T - iPhone 4 Black 32 GB

All the factories that produce iPhone are located in China, there are many factories, so each has its own identifier (6Q, 79, 7R, 7S, 7T, 7U, 7V, 82, 83, 84, 85, 86, 87, 88, etc. .d.). If the iPhone was under repair or was subject to a warranty replacement, then Apple changes the factory identifier to 5K, 7K, 8K.

Explanation:

  • blocked - this means that the phone is locked under the operator and accordingly he will not call with other cards! Whatever you are told to make a European out of such a phone is impossible, only soft unlock.
  • unlocked - this means that you have a European telephone in your hands, which accepts cards of any operator.
  • blocked , but with the ability to remove the sim-lock on additional conditions - this means that initially all phones are locked, but on additional conditions (for an additional fee, apparently), this lock can be removed, but only with the operator himself, on the forums of this nobody will do it to you.

One of the options to find out if your phone is locked , you can use the utility f0recast

Just connect the device, run the utility and see the item - Unlockable? : Locked or not (If Yes, it will be prompted with what to unlock)

Another way is to open Cydia and see if ultrasn0w or yllowsn0w is installed. If installed, then with a high probability it can be argued that the phone is locked .

“You tortured us with your codes!” Some reader will say and will be right, because there are serial number verification service using which you can enter the iPhone serial number , press the button and quickly get all the information related specifically to your phone model.
