iPhone 4: iPhone 4: no Wifi and only works for a minute on Docking System

Wed, 05 Apr 2023 11:49:00 -0700

Hallo everyone,

I have a iPhone 4 which battery got swollen up while it was in the Sony Audio Docking System (RDP-M5iP). I replaced it with the Tutorial on this website but now it only turns on when it is plugged into the docking station (only for a minute or so until it restarts). I tried to charge it with the standard charging cable but that did not work. It was not even visible on PC when I tried to make a Back Up. Next I tried to make a BackUp to ICloud while it is plugged into the cocking station but the Wifi does not turn on. To be more precise the wifi option was gray.

I really hope someone can help me with this problem.
Thank You in Advance

iPhone 4: iPhone 4 ticking when charging.

Sat, 11 Mar 2023 17:57:00 -0700

I recently replaced the battery on my iPhone 4 running on iOS 7.1.2 but it was turning fine for a few days but recently, the battery died and I tried the charge it but it starting ticking at around the top. Now whenever I try to charge it, the apple logo appears for a few seconds but turns off and ticks for a few seconds and the apple logo appears again and the cycle repeats when its charging. What do I need to do to fix my iPhone 4?

iPhone 4: Replacement battery great but screw holes no longer line up

Thu, 29 Dec 2022 11:29:38 -0700

The replacement battery seems to be working fine but when I snap it in, the holes in the battery connector don't line up with the holes in the main board. Did I do something wrong? I got the back cover on and I probably don't need to worry about the connector disconnecting so don't worry about it?

iPhone 4: New iFixit batter won’t charge

Tue, 19 Jan 2021 17:29:32 -0700

I ordered a new battery for an iPhone 4. After installing it, the phone would start up and preform normally but wouldn’t charge. When I put the old battery back in it did charge. Is this a software issue, or did I get a defective battery and deserve a refund?

iPhone 4: iPhone 4, Nand is encrypted?

Fri, 18 Dec 2020 11:42:30 -0700

Hi everyone,

I've an iPhone 4 locked in a boot loop .. And if I try to update this one with iTunes an error 9 occurs. (At the beginning of update, progress bar under apple logo, this fu***** iPhone restart and go to restore mode).

So the question is always the same .. How I can retrieve the data into the nand ? I know all recent iPhone are encrypted with CPU and other chips on logic board. But the “recent" iPhone have a secure enclave, the data security is extremely important.

I've bought some iCloud locked logic board for try to change cpu, nand, baseband cpu, baseband memory and pay chip. But I don't have a good result ..

It's possible to read the data into the nand with a flash reader on a iPhone 4 ? Or no, the data are encrypted ?

Thanks!

My kid spilled a cup of kool aid into the port for my charger and I dont know how long it sat there for. So i turned it off and left it alone standing up to drain. The phone works but the screen looks like lined paper. Is there a way to fix it myself? And the battery does not come out.

iPhone 4: Is my Logic Board broken?

Thu, 23 Jul 2020 11:24:09 -0700

Hello! I’ve just taken the Logic Board out of my iPhone 4 because I’m going to swap it into a new iPhone 4 so that I can keep all of the serial information and stuff like that.

I’ve noticed a “tab” looking thing poking up on the top of the logic board and I was wondering if this was a damaged part? I’ve left some images for you to look at.

iPhone 4: Changed screen successfully multiple times but iPhone doesn't work.

Thu, 30 May 2019 04:51:33 -0700

I have a iPhone 4 running iOS 5. Lately I ordered a screen replacement for my iPhone 4 since the old screen’s logic board connector broke. I got the screen and it was in mint condition but after I installed it. I have order quite a few screens and none of them worked. I checked the logic board and the connections and everything is in perfect order. I also checked the battery, dock connector and all of the screens. They work perfectly as well.

I don’t know what is stopping the screens from working.

iPhone 4: View my hidden iCloud password?

Fri, 18 Jan 2019 10:47:43 -0700

My iCloud password is automatically populated when I try to log in. But. The password is hidden, as in the round radial dots, instead of visible characters. No problem, right? Wrong. It comes back telling me my password is incorrect. I can't see it. I can't remember it. I've tried IN ENDLESS VAIN to reset it. (That's a joke!). And I do not store/save passwords. So. How can I:

Change the necessary setting to make passwords visible instead of hidden? Or,

Change my Backup from iCloud to my Google (i.e) acct? Or,

Any other possible idea.

Main goal:

Backup (or copy) ALL existing data on the iPhone to ensure it will never be lost or erased as I am not using that cell anymore. (Or Apple products for that matter!)

iPhone 4: Boots, wont charge, stays stuck at 100% after battery flat flex repair

Mon, 14 May 2018 05:31:53 -0700

I have a iPhone 4 on which I managed to rip the battery flat flex cable. I removed the flat flex and connector altogether and soldered wires directly from the battery protection board to the logic board (I’m planning to get a new phone anyway and I was too lazy to do it properly and use the old connector). I tested it and it worked perfectly, I then proceeded to electrical tape it up and put it back in the phone. This is most likely where the problem occurred, I must have shorted something when putting the battery back in. The phone shows no signs of life until I plug it in, then it shows the flat but charging symbol for about 10 seconds and then proceeds to boot. The phone boots up all the way and shows between 94 and 100% on the battery indicator (the value is seemingly random every time I boot it up) but dies immediately when unplugged. If leave it plugged in it will occasionally reboot. I believe the problem is most likely the battery protection board, the cell measures 3.5 volts which is normal but the battery protection circuit is only outputting 1.2 volts to the phone. The circuit must be working to the extent that the phone can detect that there is a battery attached otherwise the phone would not boot. I am not 100% sure if this is a problem with the battery protection board or not, the low voltage may simply be due to it going into protection mode cuz the battery is almost flat. I was wondering if someone more experienced with iPhone battery issues than me could provide suggestions.

Thx

iPhone 4: Mystery chip in slimstack connector - smallest I've ever seen!

Wed, 07 Mar 2018 08:24:23 -0700

It's been a while since I did this iPhone 4(?) repair but going through some old photos I came across this super-closeup of a tiny chip that I wouldn't have even seen if it hadn't glimmered like a bit of loose micah. I don't remember if this was the connector for the screen or what, but I do know that the replacement part (are they ever oem?) didn't have it. I've never seen anything like it. It reflects rainbows like a cpu wafer and it's under glass, apparently. Anyway, didn't find anything on the internet anywhere, wonder if anyone has some info.
