I've tried to restore it using itunes several times. Sometimes it worked, but i couldn't get past the "hello" screen as the home button doesn't work anymore... I had to turn it back off in hopes it would start at language selection screen. Unfortunately, almost every time it shuts off it would go back into a boot loop. I've tried reconnecting the old screen too, but it's still boot looping.

I'm wondering if this is a software issue or if it's a hardware issue. If it is a hardware issue, is it the screen that sends it into a boot loop or can it be due to something else?

Any help would be much appreciated!

I'm buying what I consider to be good quality screens, certainly not cheap nasty ones. I'm installing correctly and testing before I give back to the customer (with the customer present) and all works great but within 24 hours they develop issues.

Can anyone offer any advice/solutions.

Thank you

About a month into having a brand new iPhone 7 i had dropped it an cracked the screen a little. When I'm using it the part where the screen is broken lights up differently. You can tell something is wrong. I went a few months like that and ended up dropping it again. Days went by and my phone would turn off around 40% then 60% and now it won't stay on for more then 10 seconds without being on the charger. It doesn't have the powering off spinning circle when it turns off it goes completely black. I don't know if i should replace the screen or if its something else. I don't wanna spend unnecessary money on the wrong things. please help. Is it the LCD cord detaching or is it my battery??? I'm so clueless. Also if the top left side of phone it looks like its coming up a bit.

another thing is iv only had this phone for 6 months.

————————-Edit————————-

Based on my readings, the capacitors around the chip are shorted. I assume that it’s the chip and not the caps themselves (I’ve tested 6 of them).

————————-Edit————————-

Removed the chip successfully, shorts and cleared and upon further inspection of the chip there is a bulge on it which I call: “The fry mark”.

Since then, I’ve tried plugging it into my computer and several wall-outlets with no luck. My mac no longer recognizes the device being plugged into to a USB port under “system report”. Itunes does nothing either when I plug it in. I’ve tried doing a soft and hard reset while the phone is plugged in, nothing. I’ve tried cleaning the lightning port. Nothing.

My question is, how can I get my data back (photos, text messages etc.). I don’t care about saving the phone, I just want my data back. Should I order a new battery and screen and try that? I live in a rural area with no repair shops around.

I'm looking for the kind of double-sided tape on the gold part on the back of the Lightning connector. I think that golden part needs to somehow stay in contact with the housing.

Does anyone know what type of tape is used?

Thanks in advance.

I replaced the screen, mic, ear piece, and any ribbons associated (its been awhile since i did the repair) and now sometimes the phone would start, sometimes it would boot loop apple logo. Mostly it would boot loop.

Sometimes when it would load, the speaker/mic would work, sometimes it wouldnt. When it doesnt work, on a phone call the "speaker" icon would be greyed out.

Ive tried updating/downgrading to different iOS versions, with no success. The board appears to have no damage done to it. Is it possible i got a bad speaker or mic and these items are stopping it from booting?

If i do a DFU mode then do a restore, i can get the phone to boot the first time, 100% of the time. This makes me think that the OS doesnt do a hardware check on this first boot. Here is a video of it directly after doing the DFU restore, then rebooting the phone

Im at a loss. Does anyone have any ideas? Got a bad headphone/mic? bad screen? idk. Updating to iOS 11.3.1 seems to make it boot more often, but still boot loops for awhile.

I have an iPhone 7 that I got in a job lot. It’s cosmetically “perfect” and everything appears OK. It was missing the bottom screws which told me it had been opened. The battery wasn’t connected inside. I connected the charger (via amp meter), it draws 0 mA. Just on a whim, I tested with a known good charge port assembly, same result.

I connected it to my desk PSU with a 7 squid, and it appeared to boot just fine (no screen connected). So I connected a screen and prompted it to boot again. Apple logo and perfectly reasonable readings from the PSU, but it just keeps looping.

I have inspected the board under the microscope (though haven’t removed the shields yet) and there are no signs of anything wrong. Liquid indicators are crisp and white, no corrosion anywhere, nothing.

I have no indications of a short, as the mA’s are well within reason, so my guess was a sensor that kept it looping, but I can’t get access to the kernel logs :(
