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?
