success..!! as it is rightly mentioned, you have to be on stock rom and the IMEI has to be 0, otherwise the DFS tool will not write the IMEI.
Question: after the correct IMEI is written via DFS, i have made another backup of the unlocked IMEI.
If i flash back the first original IMEI would the phone be locked again?
unless i'm doing something wrong, when i have flashed the "fake" IMEI i'm losing the quick setting buttons on the quick drop down menu. Even if i flash another stock rom still the same. If i flash my backed up IMEI i get that functionality back
*edit* forgot to mention that here
under section 6 there is a 5irom (tookit download links) that zeros the current IMEI. I haven't tried that, but if that works then flashing again another stock update to 0 the IMEI i guess it won't be necessary.
