    IPhone 11 Temperature Sign

    Hello, Namaste.
    We have an iphone 11 for which we had changed the NAND IC and upgraded from 64gb to 128gb.

    After upgrading the iPhone shows a Temperature Sign but there is no heating in the board. We did a lot of trial and error and found that whenever the Charging Flex and Power Flex are connected together the sign shows. If either one is removed there is no such sign.
    We replaced the lower board just to check if there was a problem with the connection pads maybe but the issue persists.
    I think we have messed up while replacing the NAND. Any help from anyone will be highly appreciated. Thanks in Advance

      Double check your pads. Watch this video on iphone 12 with the same fault.

          Hello Mon2, the pads seem to fine. For double assurance we even swapped the lower board. The problem still persisted.

                  iPhone 13 mini not booting, shorted test pads
                  by bogosort
                  Hello everyone,

                  I am trying to diagnose an iPhone 13 Mini that does not boot. (Amp meter shows a couple milli amps then goes to zero, looping).

                  Here are some measurements I took :



                  Is it worth trying to repair this?

                  Thank you...

                  iPhone XS Data recovery from NAND flash
                  by Spider1211
                  Hey guys, I have an iPhone XS which came in as dead. The phone was not worked on before (I was the first to open it). After diagnosis (Splitting board, etc) it's confirmed to have a shorted PP2v63_NAND line.

                  Removed the NAND flash and short is gone on the board. Measuring directly on the NAND, there is about 2 to 15ohm to ground.

                  Is there anyway of backing up data externally in such cases (Client has some very important files and no back ups)?

                  AcuRite 5 in 1 temperature sensor replacement repair
                  by CapLeaker
                  Got a new victim:

                  AcuRite 5 in 1 Iris outdoor weather station not updating the temperature / humidity anymore. The original sensor is a SHT21. Also there are identical other sensor manufacturers. I chose the HTU21D to replace the original SHT21. Both have identical specs. I've had two failure modes with these sensors.
                  A: outside temp stuck at -40? It's cold here at times in Canada, but not that cold!
                  B: stuck at some temperature and maybe updating once in 12 hrs or so.

                  Easy solution is to go to AcuRite website and purchase the sensor. Right?...

                  IPhone 12 ProMax - Thoughts of (not so young) apprentice
                  by Srdjan01
                  Hi guys.
                  I'm working on my first board reballing.
                  It's iphone 12 pro max and I made a mistake(s), but now to learn something, I hope.
                  Either I overheated the board and two ics fell off on it's own, or I clumsily took of top board and knock them off. Adrenaline was high at that moment so I do not recall best.
                  I repaired the damage by putting these components back in place. In some moment I begin tinkering about my future steps and about the fact that I have used low melt solder (138C) to put those components back. My line of thoughts was something like, if I use same solder...
