Z fold 4 wifi cannot turn on after firmware upgrade

[timtt]

Anyone encounter Z fold 4 wifi cannot turn on after latest firmware upgrade in July? Any solution?

Hi, if u still have basic warranty coverage, I would recommend u to visit the service centre, however do note that any data not backed up, prior to the visit, will be gone upon handing over the phone to the Samsung team.

Thanks for the suggestions. Guess have no other options after look through some other postings. Very disappointing with samsung software QA.

No problem. Hope u get ur Z Fold 4 fixed soon. 🙏

Tech support asked me to do a soft reset of the phone and it works for me.
Press and hold volume down button + power button till phone restart.
Hope this works for you too.

I end up send it in for servicing. They replaced screen, entire external case, hinge , and battery. Almost everything except mainboard. What an firmware update can damage!

[JP19]

Yeah same for my Z Fold 3 too. Replaced screen.. is it when they replace the screen, the battery and hinge will also be replaced too?

[timtt]

Yeah probably easier that way.

[JP19]

Ah I see.. so that means my battery probably got replaced too.. as I thought only the screen and hinge were replaced.
