Re: simlock.sa

Hi

 

Few phones stop accepting sim cards if they're locked to network operator and are flashed with a firmware using flashtool.

So I can say that you have a phone that is locked to network operator ? If yes, then you have no choice but to get it unlocked from your carrier by paying a fees that the operator would charge.

 

One must always flash a firmware that does not have "simlock.ta" file in it. It should not be even bundled within the ftf. However , those people who don't know, do not exclude this .ta file while creating ftf.

 

Branded phones get locked when one tries to flash a new ftf with this simlock.ta file over the old one that's already present in the phone from the network operator. Even if you re-flash using flashtool, it won't work at all.

 

It's not a problem with the flashtool, not a problem with your phone. It's just that there is a software in the bootloader that is supposed to stop people from unlocking their phones.

Once you pay a fees to unlock, you would be able to use any sim, and your status of "bootloader unlock allowed" will change from NO to Yes.

Re: simlock.sa

Are you sure you're using the correct FTF file for your model? This file will be ignored if you're flashing on an SIM-unlocked (SIM-free) phone.

Re: simlock.sa

@Gehad

What model do you have? Do you have a custom cut SIM or original one?

Re: simlock.sa

Actually I have a feeling that you are using a wrong FTF file, please double check that you have the correct model downloaded.

If you are totally sure, them I'm out of suggestions.

 

@Nabeel @alexdon @uliwooly do you have any thoughts?

Why such a problem in the flashtool?
