Again, Apple took a working phone in for repair. They tore out the old bloated battery and damaged the charging flex cable.
After their “repair” the phone would not stay on longer than 3 minutes. Having broken the phone, they assumed they were going to replace the phone and only pieced it back together leaving many screws, shields and disconnected ports. They quoted me the Data Backup Clause repeatedly. They said that they don’t fix bloated battery phones. However, it’s exactly what they did. In ripping the adhesive away, it appears the charge flex cable was damaged. I got the phone back missing motherboard connection plate screws, and a variety of other missing screws including both pentalobe case screws. There was no way to make a backup to secure my data.
Once I learned about the probable charging flex cable error, I was able to retrieve the Diagnostic log on the phone which indicated the “thermalmonitord was not seen”. Putting @teetopp’s thoughts into action, I ordered a new charging flex cable ASIN B07WNCS21N kit, re-opened the phone, disconnected the old flex cable and patched in a new one with the case open to confirm this would fix the problem.
The phone powered up and stayed on reliably plugged into a charge cable and on battery power. Since that worked, I successfully backed up my data to both the Cloud and to a local computer. Data completely saved!
For over $500 less than datasaver’s, I just used the cable outside the case plugged in to the motherboard. After wiping the phone, I returned it to Apple in their repair box for a replacement iPhone X. Though I won’t have an M product number phone anymore, I’ll have a reconditioned model with a warranty. I’ll be able to sell it or hand it down to my kids.
While all this was going on my wife needed a phone— when this is all completed, I can simply setup the new phone. What a PITA but a good learning experience. Don’t EVER take your phone that’s not backed up to Apple. It’s their first go-to solution. In most cases, they’re business model is just replacing the device rather than fixing it.
Given the number of missing parts, I decided to just let them replace the phone rather than using my new kit to fix mine. Thankful again to those here at iFixit.
