iPhone 7 boots, charges but no data access
I have a weird situation, an iPhone 7 came to me, it boots fine and charges. I replaced Tigris (because with freeze spray this got very hot quicker than any other component) and it asks you to Trust the device, then the connection times-out according to 3UTools.
I did reflow Tigris again just in case some solder balls weren’t 100% good - same situation.
PP1V8_SDRAM is giving a Diode resistance reading of 158 when schematics say it should be more around 280 …
I have freeze sprayed the board and PP_VAR_SOC gets hot first and so does PP_USB_5V0 in the top right corner of Tigris.
I might order another Tigris and try again, but any thoughts on this?
Is this a good question?
