1 Did somebody already transformed Air 2 GSM in WIFI?
It's well known that Ipad GSM blocked by an Icloud account can be turned easily in WIFI only, after a small soldering operation & a restore via Itune.
But since Ipad air 2, the things have turned more difficult: after the restore operation you will notice that the wifi functionnality is disabled . The only solution is to jailbreak the Ipad (assuming that you will take care not to restore the Idevice with the latest IOS version). Not very convenient , especially knowing that you will not be able to sell the Idevice because any full reset operation will disable again the Wifi ability.
But I found this solution. looks nice but a bit harder that usual. (well! removing the digitizer of an Ipad air 2 without breaking anything is already a pretty difficult task)

Did somebody already operated like this ?
Ist dies eine gute Frage?

The method mentionned in this forum isn't good for the Air2 as you will need to jailbreak the Ipad after restore. (if you can).
Have a look to the method mentionned above with the link sent. It's far better. In fact looks like the original Wifi chip put on the Air 2 GSM is different from the one installed on the Wifi only version. So , if you don't change it , the restore operation will not be 100% succesfull as the wifi drivers won't match with the original chip installed. To be checked indeed.
