I have replaced the loudspeaker on an IPhone 5s...

The phone worked well before, the only problem was no sound.

Now it wont boot into IOS.. When i press the on/off button, it shows apple logo for 1 sec, and then screen goes black. But i can see that there are light in the screen (on the side when its not assempled),

If i try to start it by holding the on/off button, it shows the logo for 5-6 seconds and then goes black.

I have tried to go to recovery mode (or what it is called), but it wont let me.

Now i have replaced the bottom cable, with jack, charger and microphone on... Still nothing happens..

I have tried to connect a broken screen, but also with the same result.

The only thing i now believe it could be, is the battery. The first time i changed the part, i took the battery out. And when i was trying to boot the Iphone, i said that there was no power on, but the phone was fulle charged before i started.

Could it be a damaged battery??

Or is there someone that have an idea of what else could be wrong???

After I replaced the LCD digitizer on an iPhone 5s, it has gone into an infinite boot loop:

1. You can see the Apple logo for about 1 min.

2. The LCD turns bluish.

3. Restarts and does the same thing again.

4. After the second time, the phone turns it self off, and it is no longer possible to turn it on again. If I remove the battery, and then up it back in, the same thing happens.

I've tried replacing the battery and cleaning the connectors with isopropyl alcohol, but no luck.

Any ideas?

Recently, while in the dark, I noticed that my flashlight (camera flash) on my iPhone 5S was no longer working when activated from the control center. I then began to debug it by rebooting, resetting and then finally by upgrading from iOS8 to iOS9. None of these fixed my problems but during the investigation, I noticed that the rear camera was no longer working as well. After some internet searching I do not really have a clear idea of whats wrong, as such, is why I am here.

This is something that I would like to try and fix myself if possible but would like some ideas of what else could be wrong here and if there are any additional debug steps. After hopefully identifying the problem, I will likely need to purchase the part(s) and doing the repair... so any thoughts or advice here would be welcome as well.

Thanks in Advance.

With this particular 5S, I successfully replaced the screen, only to discover that the part was faulty (defective digitizer). However, I know that Touch ID was functioning after this first screen was installed because I did test. I then installed another new part, everything went well and the part tested fine this time. I did not specifically test Touch ID functionality, but I do know that the home button was working. I've always figured that if the home button is working, then Touch ID is going to function.

The customer called me today to let me know that Touch ID is indeed not functioning at all, but the home button is. This seems very strange to me, and the only thing I can think of is that I didn't get the home button flex cable connector properly seated when I put everything back together. I will have a chance to open the phone back up tomorrow, but in the mean time I was trying to do a little research on potential causes for this as well as potential fixes. Of course, my hope is that removing the bracket, disconnecting, and reconnecting the flex cable will do the trick. Of course, unfortunately the simple solution isn't always the answer.

Numerous searches on here, Google, and other websites have turned up nothing with regards to this problem. Everything I can find relates to the unique relationship between the original home button cable and the motherboard, but that's it. I did find one person that had Touch ID functionality, but no home button functionality. Similar but still different enough to not be too helpful.

So...any ideas out there? Has anyone else come across this issue? Thanks in advance for any help!

When I got to steps to remove adhesive tape, unfortunately the tape tabs just went off (just tore off) without removing adhesive from underneath the battery.

These are steps 21-25 here: iPhone 5s 电池更换

How can I still remove the old battery?

I was not able to get it into DFU, whenever i plug the phone in the the laptop and press the power button to turn it off, but the apple logo apears after 1 second and its back to the recovery mode again.

These are the two things I was looking;

The first, LOCA (Liquid Optical Clear Adhesive) Which is applied on the screen after separation and cleaning then after the removal of bubbles it is then cured under a UV lamp.

The second, OCA (Optically Clear Adhesive) which comes in pre-cut sheets that are applied to the LCD and the glass is attached.

I was originally leaning towards LOCA, and now OCA, but I have queries with the pressure methods of removing residual bubbles in the gap between the glass and the screen. There are two ways to remove bubbles, an autoclave, and a vacuum chamber. I am wondering, for anyone who has experienced, which works better for what method? Also, if the vacuum chamber is a viable option, do you think it would be possible to make your own (having the knowledge and tooling of course). Is heat necessary when removing bubbles? To my understanding it works best at roughly 60 degrees centigrade(140 degrees Fahrenheit). How do you heat the screen in a vacuum? Would any autoclave work? Or would I need to fork out the $1500 for a purpose built autoclave? What pressure is required for these bubble removals? I'm looking for the most cost effective professional method for performing glass only repairs on phones, while still having some level of automation and a high success rate? What do you guys recommend? I really appreciate any tips from guys already doing this. Thanks so much! :)

P.S. Could anyone explain exactly how each bubble removing method has an effect on each type of screen adhesive? I have heard that using an autoclave with LOCA would make it spit out the sides? The vacuum chambers make the bubbles expand and then come out the side, how long does this process take? It just seems to worsen it while looking at it. Sorry for all the questions but it's a lot to invest, especially for someone of my age (15).

Sorry if this belongs in Meta, I wasn't quite sure.

The back story on this phone is that I purchased a slightly damaged black iphone that had a cracked display and bend case (corner). The phone functioned fine, as the damage was only cosmetic. The touch ID feature worked flawlessly. I decided to purchase a donor phone off eBay that was white (my preferred color). I swapped the logic/mother board out of my "damaged" phone and put it into the white phone. The new phone worked well, except the touch ID wouldn't setup. My research pointed to the problem being the home button (touch ID sensor) from the white phone was not compatible with the logic/mother board from the black phone. Apparently the touch ID and A7 processor are paired together when phone is manufactured and a replacement touch ID sensor will not work.

Knowing this, I purchased another donor phone that was in pristine condition and black in color. I swapped the logic/mother board out the the phone again and replaced the home button (touch ID sensor) and lighting flex into the new black phone. So the current phone setup has the originally paired logic/mothe board, home button (touch ID sensor), and lightning flex cable. Despite taking great care to ensure no parts were damaged and everything was installed correctly the phone still fails touch ID setup.

I have repaired several dozen iphones and I am very confident that no parts have been damaged during my repairs. I have tried restoring phone to new and the setup for touch ID still fails. I have tried both 8.1 and 8.1.1 ios software...no luck.

I am at a loss. Did exposing the A7 to an unpaired home button permanently disable touch ID forever (even after reintroducing the originally paired sensor)? Is there a security feature the permanently disables touch ID when a non-paired sensor is installed?

I visited my local apple store and talked with a "genius." I was told the touch ID feature should work, but I wasn't convinced that he was confident in his answer. Any ideas?

We are iRepairit here in Atlanta. Recently- not sure if we have defected screens, a lot of repairs have been acting up. On the iPhone 5S and 5C, it's like there's a ghost controlling the phone. Numbers, contacts, and apps all are being used without touching the screen. This happens on the iPad mini if there's static electricity but we know the fix. However not sure where that could be coming from in the iPhone.

Any ideas?

I tried doing reset network settings, and even it all out restore, with no luck. I've also tried ejecting the Sim card and reinserting it. I still have the same problem.

I googled around a little bit and found this website suggesting that the antenna and it may need to be fixed on the iPhone five model. The parts on the iPhone 5s, but I can't find any type of repair list it for the cell antenna.

Is this possible? I don't see any type of package on iFixit.

Thank you.
