IPHONE4S Firmware upgrade official version 5 0 1 9a405 , 5

Landlord, please you and me, a very simple solution! Turn on the network, turn on the cellular data, and then turn it off immediately, try to hit ** again, and if this situation occurs in the future, it will be OK to switch on and off the cellular data!! If you still can't play, continue with the previous steps.

Itchy hands, as soon as I saw that there was new software that also solved the problem of power consumption, I did not hesitate to rise. Can't make or receive calls**, can't send or receive text messages, and the signal is full. My SIM card is a small card that I just changed to mobile.

Change my husband's SIM card (my husband uses four generations and subtracts the card by himself), everything is normal. Decisively go to the mobile to change the card. It's normal after changing.

A false alarm... It's okay, it's okay.

I used iTunes to recover it just now, and I changed it to a Unicom card, and now I can play **.

Try switching back to the mobile card after a while.

It's okay to be connected, but it's not possible to move!!

Turn the honeycomb off and on, or turn it on and then tube, and you can restore it.

My plus version also has more than problems! The machine card is not compatible.

I also have this problem, I don't know what to do, I went to the authorized repair point today and asked, and he said that maybe there is a problem with the machine itself

Me too, I've already moved and changed the card twice. Damn it.

Really, I've seen that many people seem to have this problem, so I don't dare to upgrade, lz, isn't it better to sit and wait.

Mine is up, there's no such problem. It's just that the Nima battery is still so weak.

Mine is the same. Rotten apples,

Mine is also this problem, solve.

Mine has the same issue.

Mine too, it's annoying to me, it's going to collapse!!

I also have such a problem how to solve.

Mine is also a plus version of the iphone4s after the upgrade can not recognize the SIM card so what to do now.

The great god has already said that it is impossible to downgrade for the time being. Apple is getting more and more domineering.

Mine is from the Hong Kong line, and it's the same way, I rub it.

What if the Australian version is the same?

There are several ways to upgrade.

Before all the methods, connect the computer and right-click on the phone to back it up, save your stuff and proceed:

3: Also use iTunes, first download the firmware of 4S (search by yourself), enter the phone into DFU (enter the method to search by yourself), press and hold the shift point to recover, select the firmware, OK, this will erase all your things, restore a most original appearance.

Since you have jailbroken, it is recommended that you use method 3.
