Yes. I have does 3 issues after using refurbish on ziphone 2.6b since I was having casual "need repair" error (stupid decision I've made!)
No Wifi / Bluetooth and phone wont ring if on sleep state but the GSM seems ok! I can make call and receive if the phone is on


I've already try DFU Restoration using iTunes and then use "iPlus -u" without success.

I manage and others menage to isolate the problem:
The infamous "Invalid Calibration data in device tree..." !!

Is always there no meter the method I use to activate/jailbreak/unlock I use.

This is a software problem and as to be resolved with software. And the problem maybe somewhere in iboot startup / baseband.

This problem makes the phone unusable since you cannot see the incoming calls.


edit: Used this method

without success. All process goes without problem/error but in the end when unlocking the phone with iplus I get that error:
Invalid Calibration data in device tree...

I hope that they are implementing another method to resolve this problem beside the up above.

and i have this problem adn many people on piace
