The Sony Xperia Z Ultra power flex looks to be the same as any other soldered on flex from the teardown pics. The steps to replace are as follows:

1. apply flux

2. wick solder off pads

3. remove flex while applying heat: DO NOT APPLY BRUTE FORCE OR YOU WILL RIP PADS it may help to add leaded solder to the solder points if you are having trouble.
