Rispondi a: iPhone 8 keeps rebooting when chargingDo a thorough visual inspection, preferably with magnification, of the area surrounding the battery connector. There are several tiny SMD components just above the connector. Of particular importance are the ones highlighted in blue below. If any are missing (which can happen when you pry the connector off), then the battery state does not get communicated to the CPU and this can also cause charging issues and fluctuating readings.
Rispondi a: Screen Glitches after back glass shatter.I would suspect that the screen was damaged by the impact that shattered the rear glass. At this point, the only way to know for certain is to try a replacement screen. Considering the cost of a replacement screen, you could always drop by a repair shop to see if they can try one of theirs.
Rispondi a: Battery stuck on 1% and restarts randomly, after screen replacementDo a thorough visual inspection, preferably with magnification, of the area surrounding the battery connector. There are several tiny SMD components just above the connector. Of particular importance is FL2400, at the top-left of the connector. If it is missing (which can happen when you pry the connector off), then the battery state does not get communicated to the CPU and this can also cause charging issues and fluctuating readings.
Rispondi a: 6s with dead PP1V8Which Tristar tester did you use? The voltages measured seem a little off, specifically the jumping PP3V0_Tristar and NAND and the 0V mon PP1V8. Because your original issue was related to a replacement battery, I would check the Tristar/Tigris circuits again. Have you tried measuring the voltage on the battery connector (on the logic board) with the Lightning port connected? You should measure around 3.7V.
Rispondi a: Front Camera and ear speaker not working after battery replacementHere is the link for the ear speaker. Here is the link for the Front Camera / Sensor Flex. A damaged Ear Speaker is pretty rare so your issue is most likely caused by a damaged FCAM flex or incorrect installation/alignment.
Rispondi a: Touch screen is acting crazy after a yearThe iPhone 6S does not suffer from Touch Disease. If your screen is ghost touching, then it is most likely just a bad screen. Replacement screens for the 6S are pretty cheap nowadays and the phone still holds it’s value and is powerful enough for daily use. I would fix it (full disclosure: I own and use an iPhone 6S :-). Contact your vendor, they may be able to help you out.
Rispondi a: iPhone 8 Plus replacement display only kit come with display adhesive?Not according the product description. Some vendors do include it though. You should order it in addition to your replacement screen.
Rispondi a: Having problems while replacing iPhone 7 audio ICIt is possible the issue isn’t with the Audio IC. A torn home button flex or issues with the FCAM/Sensor flex can also cause boot issues…and the audio issues may be caused by the AMP IC’s or any other number of issues on the logic board. Have you reballed the Audio IC 6 times as well or are you using new ones? If you have reballed it many times, I would try a new and fresh IC as these glass (silicon) IC’s are quite fragile. Put the underside underneath the microscope and inspect it closely. You should notice that it has a “circuit-board” look to it. It’s more than a look though, the IC is an actual multi-layered circuit board “etched” via photolithography and traces run pretty much right up to the edges of the silicon wafer. If even one of those traces is damaged (usually by tweezers), the chip will fail in some way. If you are already trying new ones, you may have a bad batch. The risk now is that the number of times you have done this could have caused other issues just due to the sheer amount of heat appli...
Rispondi a: iPhone X Won't Charge or Turn OnWhen troubleshooting charging issues, I would do the following (in order): (1) Always try another Lightning cable and charger, preferably Apple original or MFi certified units. (2) The Lightning cable 8-pin connector should be sitting flush with the housing and completely inserted. If it is not, there could be lint/dust/debris inside the port impeding a proper connection. You can clean it out with a toothpick, fine point tweezers or a dental pick. Just be careful not to damage the pins inside the Lightning Port. (3) Change the battery. The battery is the weakest link in the entire phone and certainly for charger related issues. It is also the easiest thing to replace. Use a battery utility, such as coconutBattery (for Mac) or 3uTools (for Windows) to test the battery prior to removal. Anything less than 70% of design capacity will require replacement. (4) If the battery is in good condition, you can use a USB Ammeter to determine if the phone is really drawing current when it says it's charging. If it isn't d...
Rispondi a: My phone won't turn on after water damage under the sim tray.With water damage, you have to decontaminate the logic board before doing anything else, otherwise there will be latent issues down the road. 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. The water is inside the phone, on the logic board and under the shields, even under the IC's. The real problem is the mineral deposits that can cause short circuits or the corrosion that is taking place as the water evaporates. Leaving the power on the device accelerates the process. The longer you let a phone sit, the more time you are giving corrosion to damage your logic board. The saltier or harder the water is, the more damage will occur. The water needs to be displaced, not evaporated. The proper way treat a wet phone is to do the following: (1) Open your phone and remove the logic board (follow this guide) (2) Inspect the logic board,...
