For example if you purchased from Verizon, then you will have a Verizon ESN. that are preset and designed so that they, the carriers, only want you to be able to use your phone with the carrier you purchased from.
#UNICDMA WORKSHOP SERIAL#
The basic reason why it won't work for all carriers is because your phone has certain numbers associated with it's hardware such as serial numbers, ESN numbers, MEID numbers, etc. Note however that this does not work for all carriers however.

This generally is or is understood to be downloading the carrier files from the carrier you want to use, such as cricket or metropcs, to your phone. The way to get those restrictions out of your phone so you can unlock new features, such as being able to use on another carrier, is to flash some new software such as a ROM.Ī lot of people want to know about flashing to another carrier. Typically the carriers want to restrict access to your phone so they program it in such a way as to do that. By flashing new ROM's or other programming you may unlock or extend the capabilities of your phone or device from what was otherwise originally intended by the person you purchased it from which in this case for a cell phone would be the carriers like Sprint or Verizon.
#UNICDMA WORKSHOP HOW TO#
For example if you have a ROM that is customized or a ROM that is from the carrier like Sprint or Verizon it will give instructions to your device about how to act and behave, such as certain icons, available connections you can make, etc. The ROM contains some of the software or information codes that tell your device how to function. When you flash something, it basically means to program or reprogram the ROM. They are more resistant to drops and breaks so the memory in them stays where its at instead of "resetting" itself.

This is not true with cell phones and similar types of flash memory such as USB Flash Drives. For example if you dropped your desktop computer in some way then there is a strong chance that by doing so you will have lost the memory contained in the ROM as it may reset itself when damaged from a drop or similar action. Flash memory differers from traditional ROM that is used in a PC or computer in that it is easier to reprogram but also more resistant to damage such as from drops or breaks. Other names it is also known by is EEPROM (electrically erasable reprogrammable Read Only memory) and nand flash. The term "flashing" has to do with the type of memory that a cell phone uses.
