Hi Joseph,
thanks a lot for the description!
I have a similar problem with the USB-C port and one of the SIM cards also permanently loses the connection, so I have to restart the device every 2 days.
But before I order a replacement, I wanted to see if I could detect a possible loose connection that I could possible solder. Or do you thin that makes little sense with such small circuits?
Also, how did you finally assemble the device? Does the back need to be glued back on? Is the residue from the original adhesive sufficient?
Hi Diggi - I think you'd end up cooking the system board if you tried to solder anything in there. The SIM card reader is the orange flex cable on the far right, and along with the black vibrator motor cable to the left of it, both have also had issues. When it happens, I have to open the case, unscrew the plastic assembly, and usually one or both of those two cables will not be secured. I just push the two cables back in place to fix.
Assemble the device in the reverse order of how you disassembled it. The remaining glue around the edges might be enough to hold the back on. Mine is only about 80%, but because I keep the phone in a case it's not a huge deal. The glue bunched up on me in a couple of spots so I had to cut those off or the back wouldn't stay on. Hard to say if the connectors popping off is due to the back not being secured tight enough. Shouldn't matter with all the screws holding that plastic cover. 🤷♂️
Hi Joseph,
You really helped me a lot!
I ordered an additional SIM module via your link above and simply swapped the two.
It was more than child's play with the instructions. Works like a charm!
~80€ for spare parts instead of 800€ for a new cell phone.
Thanks a lot, mate!
Fantastic, so glad you were able to get it fixed!
