[Sumit Kumar]

I am using E1750 with T-Mobile version11.126.03.01.55 (bsnl 3g), while updating version to 11.126.13.00.157, it is asking password. My EMEI is 353558042732735. CAN ANYBODY GIVE ME PASSWORD, ALSO AFTER UPDATE IT WILL GET LOCKED, HOW TO UNLOCK THIS
Request give attention soon.

It appears that your data card is locked. All firmwares with the highlighted digits 11.126.03.01.55 other than the 00 are branded firmwares. These must be used with locked modems specific to a telecom brand. If you use such versions with unlocked modems, it will get locked again. That's what happened to you now. The firmware 11.126.13.00.157 is not specific to any telecom brand so can be used with unlocked modems.

You should now unlock your card first. Only then you can update your firmware. You should have taken special care while updating firmware.
