"iPhone 7 still on bootloop even after updating the software"에 답변When you are in DFU mode, the screen will be black. This sounds like a NAND (memory) corruption issue and the device will most likely have to be Restored, not updated. Try a proper DFU again and choose the Update function to see what happens. If it doesn’t work, then you will have to do a Restore.
"Home button no return to home"에 답변There may be some damage to the screen, specifically the flex that runs underneath the heat shield and connects the actual Home button to the logic board. Seeing as how you have two devices, try the working screen/Home button combo on the first device to see if that solves the problem.
"If I transfer my logicboard on an identical iPhone, would I lose data?"에 답변Yes, the logic board is the phone and if you were to put it into another housing, it would just work as it did before. However, your logic board is most certainly fried. The water and subsequent corrosion is what causes the most damage. You made things worse by letting it “dry” for several days. All that does is allow the corrosion to fester and spread. The proper thing to do with a water damaged device is to remove the board, preferably remove the shields and do a good soak in high purity IPA to displace the water. The board may be repairable but in my experience, it will probably be a flaky phone with all kinds of weird problems. The exception to this rule is when the water damage is very localized to a non critical area. In the case of the iPhone 6, when C5201_RF gets shorted and nothing else, then the phone can be 100% recoverable. But when the water gets to the PMIC, NAND, CPU etc, you usually have more latent issues. At this point, you should consider getting the data to be a success, never mind the...
"Swapping the guts of one phone into the body of another?"에 답변You only need to replace the logic board, assuming that nothing else was damaged when the frame bent. EDIT Yes, kudos to Evan who rightly points out to transfer over the Home Button as well if you want to retain Touch ID functionality.
"random crashing / rebooting"에 답변I doubt anything “came loose” as everything is tightly secured in an iPad Pro. Everything you say points to a logic board issue. What is more concerning is the potential history of this device and how (and by whom) was it “refurbished”. There’s a very real possibility that this device was always going to fail at some point either due to a poor repair or that something more fundamental was going on at the logic board level. For example, the screen may have been damaged, repaired and sold as refurbished. But a series of drops over time meant that the logic board was a ticking time bomb, ready to go off at the next, slight impact or drop. As Peter suggests, you could open up the device and inspect it for anything obvious however keep in mind that the Pro series iPads are much trickier to work with the the Air/Air 2 and their clones (iPad 5/6) and you could easily cause a lot more damage just taking it apart. Take a look at the guide first. If it is a logic board issue, board-level repair can be considered but...
"panic-full i2c3 mic-temp-sens1 after replacing the Screen Glass"에 답변You might want to try a new Lightning Port Flex (or one that is known-good) to see if that solves the problem. If that doesn’t work, then consider the following suggestions. Start by testing a bare-bones setup. Disconnect 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 (new or known-good) 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 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 boot, then you most likely have a logic board issue. You could send it (or find a local) to a repair shop that specializes in micro-soldering repair. Sometimes the fix can be straightforward (i.e. a...
"Very vague boot loop after replacing frame on iPhone 8+"에 답변Doing a housing replacement is a hornet’s nest of potential issues. So many changes at the same time, it becomes difficult to figure out what is causing what. I would remove the logic board and connect only the Lightning Flex and battery and then connect it to an iTunes enabled computer. If it is fully recognized, then add one component at a time (always remember to disconnect the battery first) until the phone stops booting and you should be able to identify the defective component. If the phone doesn’t boot even in a minimalist configuration, then you may have damaged Lightning Flex (rare)or the logic board (more common).
"black screen and no power after battery and screen replacement"에 답변The connector for the Volume Button flex should have no impact on the device booting or not. The challenge here is that you made multiple changes at the same time and it becomes harder to understand what works and what doesn’t. Let’s eliminate some variables by disconnecting the LCD and Digitizer. While you’re at it, and depending on the state of disassembly, I would also disconnect the FCAM, RCAM and Headphone Jack flexes from the top part of the logic board. Remember to always isolate the battery first, as shown here. This is a critical step that too many people overlook or think not important. Essentially, you should have only the battery and the logic board connected (don’t forget to put the screw in place to secure the battery connection once your done). Now connect the iPad to an iTunes enabled computer to see if it is recognized. If it is, then you have a good logic board and you should add one flex/component at a time (remember the battery!) until you figure out what causes the issue. If it isn’t...
"iPhone wont turn on after display swap"에 답변I would take a step back and start by re-installing the original screen to see if the problem is consistent with the screen or the phone (logic board). I would also closely inspect the flex and connectors to insure there was no damage from the repair. Quick question - did you disconnect the battery prior to removing the display, and connect it only after the display was re-connected? The other thing to try is to remove the screen altogether and connect the phone to an iTunes enabled computer to see if it is recognized. While you’re at it, you could also remove the RCAM and button flexes and keep the phone in a minimalist state. My concern here is your cleaning process. In theory, distilled water in contains no minerals and is non conductive, so you’re approach to cleaning the device is sound. However, in practice, its possible that the “pure” water you used was not as pure as you thought or were led to believe.
"No image after replacing iPhone 7 screen"에 답변This sounds like you may have a logic board issue and certain screens are more or less “demanding” in regards to current draw. Take a close look at the screens your are trying. There isa difference between an original screen, a good quality aftermarket or a cheapy screen. Ironically, some cheap screens work really well and in other cases, they don’t work well at all. If you are a shop, or have access to multiple screens, try to see if the is a relationship between the type of screen and the problem. IMHO, if an original or high quality screen doesn’t work (assuming no flex or connector issues), then you may have a partially damaged LCD drive or backlight circuit.
