content: @Rasz - Hi, yes, it is a module.I dig to avoid needing to remove the hard-disk.Some concentrated on the other end, where the big MLCCs reside.I was hoping that someone already dig this end of thing.

content: you made the hole in the chip?I thought you just wanted to replace the hole chip, I never read that someone replaced a sub-chip...Why not exporting your data from the chip and then replace the chip and then restoring the backup?

content: 4S models sometimes had this issue too. Reflow will sometimes work but it didn't for one I had. Then module replacement is the only option however with that horrible PB free muck you have to get the PCB pretty hot so not to risk pulling a BGA pad.Not a simple job for those without experience.

content: Hi, for the 'S' model, the wifi module is linked/paired with the Hard Disk, so just changing the module with a 'New' One will not work.Blindly soldering a new one in, I transformed myself to mere welding/soldering technician.? and will rob the spirits & fun out of "REPAIR" isn't it.If it's discrete, we explore.@ElecSeb - WTF, you made the holeYes, Welcome to Electronic. Thanks.

content: I am not a big apple fan/user, but there are multiple tools which can also extract data by using the cable.Would this not be a solution to you? I understand that when wifi is not working you cannot do cloud backup by wifi, but is the phone actually turning on?Furthermore, what you can do (just a thought), buy a new chip. User acid to extract/expose the needed wifi chip. Then extract.Next step is replace in the same way in your phone. Do the backup and then replace chip?(And if you do so, please post the progress here, since I am curious about the progress, and if you succeed)

content: @ElecSebFirstly, when the chip heats up, it means there is a short circuit, therefore you do not proceed any further to power it up and risk damaging the PMUs and other chips in the HP.Secondly, there is not a need to extract any datas from the Wifi Chip. I could have easily "unbind" Wifi from the Harddisk and replace a new Wifi Module to resolve/repaired the HP.Maybe it would help if you read the question in my original post.I appreciate your efforts, though. thanks.[there are many pros that dug the module. One day, a forum will piece all the discoveries together]

content: Quote from: Armadillo on December 04, 2018, 07:50:33 amUntill now you never mentioned you are just "experimenting" instead of "repairing".I have reread all your posts in this topic and in none of them you mentioned you did not want to "save" nor to "delete" the existing data.So to be honest, it would be nice if you stated earlier that it was just for the sake of fun and out of curiosity.Furthermore I have no real experience with Apple stuff as mentioned before and responded to your main question of your FiPo:Quote from: Armadillo on November 24, 2018, 02:25:12 pmHere you say to my understanding 2 things:1. I do not want to lose my HD, because of XYZ...2. You ask for a specific solution, namely a new wifi chip, which is naturally not for sale so I tried to give you a solution which I saw yesterday by accident.So to be honest, if you want a clear answer (from anyone responded to this specific topic) next time make your post complete!Since it is now clear to me what you want/need, it is not my cup of tea so I leave this topic as is.
