I have saved, MINIMUM, 5o+ iPhones that had liquid damage utilizing this exact method; maybe youre not as experienced in this method as YOU think. My guess is the corrosion that I cleaned was blocking, shorting, or bridging something on the board or thru one of the flexes. Regardless, they did not work when the customer brought them in, and they did work when I finished. Unless I have some weird devine intervention happening in my store at night and should change my store name to "*** Cell Repair", they were repaired by me.


I told you I have a lot of experience in taking apart the phones, replacing parts, and cleaning Mobo's from liquid damage. I also told you I did not know the components on a MoBo, or how to read the schematic.

Why is it some of you feel the need to belittle despite being told by the ones youre belittling, they are novices. I havent been on this site in quite awhile, but hope this is not the direction it has turned. Hopefully it's just a few on this particular section.

The guy you don't want me to piss off said in a previous post, the fix for a error 21 and 16xx on a 4s was to remove some "Cap" on a certain part of the board. He referred to a pic that was a 4g or CDMA Board, not a 4s. I just wanted constructive clarrification; that's all.
