-The BB Change Other iPhone 4 Broken BB 100% After Changed The Same!

-All BB Put To IPhone Check IMEI Become To Unlock (Connect To iTune For Unlock)

maybe your imei starts with 0499xxx , this the result to change only the baseband flash ic , you must to change baseband prosesor too , for avoid imei mismatch

if your imie is 0499xxx you cannot activate and have a valid unlock ticket from apple , even if your phone is factory unlocked

your only chance by software its hacktivation and wait for unlock sw based solution , or even better a hardaware based solution

Yo can't change Baseband now,
now apple also starts Verify Serial Number with IMEI too.
it will not be activated untill you have Matching Serial+IMEI.

We Can Change Serial Number Or Not?

crashnok3230 · 08-04-2012, 23:40

I think not, because the Nand flash has ECC, an automatic error correction. And if on the programmer to change the serial number, it will be recognized as an error and corrected.

spaxx137 · 08-05-2012, 00:18

3 years ago that is the same problem of iPhone 3G when flashing IC to change the serials to become factory unlocked. Changing serials or chips related to baseband or activation tickets will have activation problems. Up to now there is no solution for this

beastien · 08-05-2012, 13:17

This must of only changed recently, had my baseband changed, and activated successfully not too long ago.
Tried again tonight "There is a problem with your iphone"

I had my activation ticket saved, and restored it. but itunes is still showing the error, and wont connect to the
phone.

schemu · 08-05-2012, 16:44

Still same problem, after restore iOS 5.1.1 on iPhone 4 with changed bb, phone don't activated iTunes.
