i9250 imei repair

[bigclive33]

hi im trying to repair the imei on a I9250, i do have the s7070 cable and i have replaced the resister to a 560k one but the operation always fails at the last part connecting via uart cable. can anyone help at all ?

Download and install latest nspro version again from : : NsPro Downloads: :
Then try again.

The phone IMEI must be numeric.
If the imei is null (unknown baseband), then you must solve the baseband problem first, then write IMEI by NsPro.

hi, the imei is currently numerical. and my software version is the current version.
when i plug in the uart cable should any of the leds (rx/tx or the on led) light up? as at present if i plug the cable in none of the lights light up. the tx led flashes when its trying to look for the cable towards the end of the process. And my cable is a new one which i bought a while ago but dont think ive ever used it b4. Is there a way i can text my box on the uart end? maybe theres a problem with my box or the cable? but the cable is new so i dont think its that.

there are many other models that require uart cable for unlocking.

I9250 however, require a mofdification on the cable for IMEi write.
Check the i9250 RJ45 cable schematic from nspro support area and compare it to NsPro S7070 cable schematic.

the main trick is in uart cable...........its need 619 to 680 k ohm resistor..........

what about t999 Imei null/null ?????

yep the resistor has been canged, and i even used a second resister in case the first one was faulty from another supplier but still no change. thinking maybe either the box is faulty or the cable. but which one do i replace first lol. the only other samsung i have to hand is an s2 is there anyway i can test the part of my box or cable on the s2 ?

just a thought, would the fact im running windows 7 64bit be causing a problem?

No. windows 7 x64 wont be a problem.
Most likely, the problem is from the phone or the cable.

For I9250 the resistor from the cable must be 560K.
There are many cable mnufacturers who build the cables according to the my schematic from nspro support area.
The problem is that not all of them fallow the schematic exactly...

Contact me by yahoo messenger and i will help you to solve that imei problem.

No connect with resistor 560K.... With 660K worked well.

thanks I will try with a 660k resistor

does the phone need to be rooted to change the imei?

No. No need to root the phone for Unlock/IMEI repair

spot on, thank you very much, I changed the resistor value to 630k (was the only vaule resistors i had laying around) and operation completed succesfully first time. :-)

thank you very much i have been trying for weeks to sort this phone out and now its done lol

now just got to figure out why google talk and camera are not working lol.

[infomobile]

With 660K worked well for mine !!!!!!!!! tnx
But i have another problem now i do not have a mac address or a bluetooth mac address. How can i find it or replace it or rewrite it with something that will make it work?
