Antwort auf „No boot - problem with Charger_LDO?”IIRC, Charge_LDO is at 0V when on battery power only and ~VCC_MAIN when charging I think your issue is elsewhere and you need to take a step back and probe your board without making any assumptions. Tristar/Tigris is a common repair but sometimes we get blinded by that and forget to look at the rest.
Antwort auf „iPhone X won’t turn on after being face down in a small puddle”With water damage, you have to decontaminate the logic board before doing anything else, otherwise there will be latent issues down the road. Sometimes water damaged phones will work for a short time before failing completely. That is actually the worst possible scenario because a proper decontamination would have probably saved the phone. Keeping it plugged in just amplifies the corrosion and can kill critical subsystems, leading to a dead phone and possibly lost data. Not every water-damaged phone is recoverable and depending on the kind of liquid (salty, dirty, filthy), sometimes the success rate is quite low. That said, IMHO, it's always worth a try otherwise we are just piling up the e-waste. You should avoid putting a phone in rice or leaving it sit, drying”, for days on end. The water is inside the phone, on the logic board and under the shields, even under the IC's. The rice is nowhere near where the water is. So while it “may’’ soak up some water vapour, the real problem is the mineral deposits...
Antwort auf „Touch issues after screen replacement”This is most likely a poor quality or defective replacement screen.
Antwort auf „iPhone won't boot and Home button is broken.”You have a lot of variables here, which is normal when you’re so deep in trying to isolate a problem. I would start by testing a bare-bones setup. Start by disconnecting the battery first (always!). Then disconnect the digitizer, LCD, front camera, rear camera and home button extension flex. Now re-connect the battery; you should only have the battery and Lightning Dock flex connected. Connect a known-good, preferably Apple-original Lightning cable to an iTunes enabled computer. If you have access to a multimeter, you could measure the battery first. If it reads ~3.8V - 4.2V, then it is good. Does iTunes recognize your phone? If so, then you should re-connect one flex at a time until the phone stops working. I would start with the Home button flex first, then add the rear camera, LCD & Digitizer then from camera flex. If the bare-bones setup does not get recognized by iTunes, then you most likely have a logic board issue. If you are reading ~3.5 volts at the battery terminal when connected to a charger,...
Antwort auf „iPhone 7 Freezing/Boot Looping”Did anything happen to the device in the days and weeks leading up to this issue, such as a drop, a repair attempt or contact with water? Assuming this was a spontaneous failure, it is probably a failed component on the logic board. The iPhone 7 is prone to several issues after repeated minor drops and flexing over the course of its life. It could also be a dead or dying battery or modular component. If you have access to a multimeter, you could measure the battery first. If it reads ~3.8V - 4.2V, then it is good. I would start by testing a bare-bones setup. Start by disconnecting the battery first (always!). Then disconnect the digitizer, LCD, front camera, rear camera and home button extension flex. Now re-connect the battery; you should only have the battery and Lightning Dock flex connected. Connect a known-good, preferably Apple-original Lightning cable to an iTunes enabled computer. Does iTunes recognize your phone? If so, then you should re-connect one flex at a time until the phone stops working. I...
Antwort auf „iPhone 7 will not stay on for more than a couple seconds”Did anything happen to the device in the days and weeks leading up to this issue, such as a drop, a repair attempt or contact with water? It’s important to give us as much background information as possible. As Chris suggests, check the battery to insure that it is capable of powering the device. If the battery is good, or if you have installed a good quality or known-good battery, then use a USB Ammeter to determine if the phone is really drawing current when it says it's charging.
Antwort auf „How to determine if iPad homebutton is original?”In 3uTools, there is an option on the main screen called “View Verification Report”. It will tell you if the home button is not an original.
Antwort auf „iPhone 4s battery connector pinout?”Here you go…
Antwort auf „My phone wont turn on”Try re-installing the orignal, cracked screen to see if it works. If it does, then you have a defective replacement part. If it doesn’t, then you may have damaged something during the repair. In that case, closely inspect the device connectors and flex to see if there is any visible damage.
Antwort auf „Mic and headphone wont work after lighting port replacement”It definitely sounds like a bad replacement part to me. I would re-install the original flex and check to see if the audio (mic and headphone) works properly. If it does, then it’s a bad replacement part.
