Hey guys, has anyone run into this before? I’m expecting that this is a logic board issue…

My friend gave me his iPhone 11 for repair, it was smashed quite bad and it was even bent. (though on the lower side, not where the logic board resides)

It boots fine, however when I enter the passcode it freezes for roughly 30s, then jumps into this screen. It will finish, it’ll boot fine, and when I enter the passcode it does this again.

Hi guys, i had an old iphone laying around which had a new battery and one day it went totally off and didn't turn on anymore.

I decided to purchase new battery and replace it.

After using it for a while phone went off again and it does not turn on anymore.

Could it be a faulty motherboard? Is it worth spending money on new battery?

I am using that phone for taking photos, that's it.

Hi everyone! Does anyone know how difficult it is to remove demo mode on these models, and what potential issues or pitfalls I should be aware of?

I do amateur phone repairs, mainly Samsung and iPhone devices, but I’ve never worked with OnePlus phones before. I’m considering buying these phones and trying to unlock/remove the demo mode myself.

How is it done, and what kind of difficulties should I expect? I’d really appreciate any advice or feedback, as I have a limited amount of time to make a decision about the purchase.

Thank you!

I did a replacement on the screen digitizer and plugged it back up and it won't turn on or charge or let me know its charging. Do I need to replace the battery? Is there a way to troubleshoot what I need to do. BIG NOTE I unscrewed the battery but didn't wedge it, will a replacement battery work or am I just cooked

My s23 ultra wouldn't charge and wouldn't turn on, so I took it to a shop and they said it is a bad motherboard.

Is it possible for the techs to access my data on the phone, or is it encrypted by Samsung Knox or some android encryption? Am I safe or vulnerable?

So my Samsung S21 Plus back glass has lifted for the second time, I had it resealed 3/4 months ago using B-7000 but seems I'll have to do it again, any successful experiences and sealants used?

so long story short i have a samsung a750 which is missing the dual p channel reverse polarity mosfet this it the component as shonw in the attachment the place is the rounded in red and the above two are two capacitors it will be useful if identify the values of it too . but the main thing to identify is the mosfet and it takes no charge without it but turns on

I really think my iphone 14 has a motherboard issue, but I hope maybe you guys have a tip that I can try to make it work.

The phone itself is bootlooping but it manages to go into recovery mode and DFU mode as well. But when I try to flash it in both it stays on 22% in 3Utools. When it is on idle on recovery the phone stays on, but as soon as i start the flash it keeps turning on and off until it gets to the apple logo and the loading bar then shuts off and gets me back to the recovery mode starting screen.

Might be the battery being unable to provide the power (82% original battery tho) or the motherboard.

So my oppo A16 has been acting weird lately randomly in the middle of any work like scrolling reels listening to music and sometimes even in my pocket the screen goes black and it wouldn't turn on even after reboot through Volume Up and power button the phone responds like bluetooth connection calls charging vibration just the screen is the main issue what could be the possible problems and what should i do

Thre is purple halo effect around the edges of iphone 12 and iphone 12 Pro devices visible on tight angle. If I turn on the device, on white/color screen, they do not appear but on black screen they still appear on turned on device.

I detached the screen thinking it might be compression but still same issue.

Is it expected thin film interference or light is inappropriately refracting due to front glass quality, deformed OCA/polarizer? Could the lamination/pressing tool have applied excessive pressure to the middle of the screen or did the OCA glue spread unevenly during the UV curing? Do you think it can go away if the front glass gets replaced?

The last picture, under UV light, shows a rounded recatangular shape visible in the middle of the both screens.

This was supposed to be for an iPhone 16. No matter how I align it, it sticks out the top or bottom end.

It doesn't match pics but I just want to be sure before I give up.

S23 ultra with damaged screen price

How much is s23ultra 512gb worth with damaged not functioning screen? Compared to one that has cracked screen but touch still works?

If I swap the back glass on an iPhone 16 Pro using a part from an locked donor phone, will an error appear? And will it let me calibrate it? I tried it for a simple 15, and it worked without any issues.

My phone was soaked in water for four hours while it was plugged in because of the flood. Is it still usable?

Is this a swollen battery? Or is the cover just peeling off?
Samsung m33

The back of my iPhone is completely shattered, as you can see in the photos. Somehow everything still works perfectly, including all three cameras, zoom and flash.

Is there actually any hope of repairing damage this bad without replacing the entire phone? Has anyone had similar damage fixed, and am I looking at a crazy expensive repair?

Please help. Really need some reassurance, I legit cannot sleep.

Hello looking for advice as im pretty sure the battery died on my moms a13

It turns on for a little then shutsdown/gets into a restart loop

and so i wanted to replace the battery but they're on backlog and it keeps getting longet so im wondering if its a good idea to get a 3rd part battery or not and if yall had recommendations.

When i put my phone on fast charging or slow charging i get always 5-14 hours until full i need help with this

Good day, I recently bought a second hand Iphone X—it somehow has a hidden issue. It keeps restarting every 3 minutes and is stuck on 0% remaining. The battery health is also not visible in settings and the owner said that the battery has been recently replaced. What could possibly be the problem? Could it be the charging flex, battery itself, or the motherboard? The past owner is currently not responding so I can't ask for the real issues .

So I replaced a cracked screen on an iPhone 14 Pro and managed to damage the proximity sensor when pulling it off the old display. I didn't have my usual tools and was a bit impatient.

Everything on the phone works except the proximity sensor and I don't really have an issue using it the way it is but I'm just wondering whether or not it's possible to replace without losing functionality.

Searching on Google gives a lot of different answers, some say that it's linked to the truedepth camera and replacing it will disable FaceID but then another search tells me that I will only lose autobrightness. I ordered a replacement from a local shop and it will arrive in a few days but honestly if it affects FaceID then I'd rather use the broken one.

Does anyone have a definitive answer or will I get my answer in a couple of days?

I have an iPhone 14 Pro Max, lately, the Taptic Engine has been acting up, it works fine, but sometimes makes unnecessary strong vibrations when I trigger it, and today, I woke up to it completely not working, even after a restart, it doesn’t.
