iPad 7th Gen A2198 wifi issue after hardware bypass - GSM-Forum

adryanbiru · 06-22-2021, 09:41

i have 2 mainboards which i have already killed gsm and changed sn/wifi/bt and wifi unlock. But the issue it is that i have already changed wifi cip from another pcb wifi only version but wifi will not work, only BT its working, ive tried at least 5/6 wifi cips but still same issue on to diffrent ipads. So the issue its : wifi grayout and bt works normally. Ive tried everything.

do you have zxw?did you check all pins from wifi connections in diode mode?im sure its not wifi chip now if you replace 3rd time but you already tried 6 times and stil same..there could be another problem..

What is the IC model you are replacing?

448 It should work

What do you mean if i changed the version, you mean if i unlock the wifi? And one more question, have you worked on any ipad 7 gsm version?

Ok so you need magiccfg, unbind WiFi in app should work.

As said you need to put in digi mode (purple mode) read pad in magiccfg and click unbind WiFi.

If that’s not problem then it is WiFi module of bad solder/pads on or around WiFi.

2 different ipads, wifi unbind already on both, 5 different wifi cip was used on both ipads, same result bt works, wifi gray out, looks like its a different bind or lock problem. Question, have you worked on any ipad 7th gen 2019 GSM version and it worked or you just think its same like 5th or 6th gen ?

Yes,
I already worked with 3 of the same without problems.

You need to change version to 2197
