S7 Edge dead
Hi guys, so I was flashing the FloydQ and once booted it asked me to put WiFi password. I did it but then it gave me black screen and the smartphone won't turn on no matter what I do and it was at 100% battery. I tried:
- Recovery combination (Home Button + Vol Up + Power)
- Fastboot combination (Home Button + Vol Down + Power)
- Connect it to the PC with windows
- Conncet it to the PC with Linux
- Tried to see if magically the ADB would find it
- Disconnect battery for hours
- Charging it the whole night (about 6 hours)
The result... -
Re: PS4 Wi-Fi chip bad joint

Re: PS4 Wi-Fi chip bad joint
If I put to ground the lef, they power on, so I think that the powerboard is still functionalLeave a comment:

Re: PS4 Wi-Fi chip bad joint
So I did like that but putting a disc won't power it up (I'm a noob and in the process I broke the power button and it's flex cable, tried to repair it but didn't worked but if I move it, the PS4 turn on led on the power button randomly)...Leave a comment:

Re: PS4 Wi-Fi chip bad joint
So none of the pad is connected to ground (I tried to see if there's continuity with the brown pad on the board, I'm a noob sorry). Also the PS4 is a SLIM CUH-2016A B01Y, motherboad SAD-001 1-981-279-21. On the primary side there's the NOR chip and the southbridge
On another forum they says that is a 22 Ohms....Leave a comment:

Re: PS4 Wi-Fi chip bad joint
So guys I think I messed up badly. I had the occasion to try an original DS4 but nothing, the PS4 was stucked. After some soldering and desolring the WiFi module the PS4 doesn't turn on. I've tested the PSU and it's fine, how could I try to locate the error? I've checked for missing component next to the area where I applied the hot gun but nothing is missingLeave a comment:

Re: PS4 Wi-Fi chip bad joint
So I kind of resolved, now the PS4 turn on and update (with the non working module it just couldn't giving me an error) but I haven't an official controller, just a nacon, and can't get past the screen where it says to press the PS button...Leave a comment:

PS4 Wi-Fi chip bad joint
First off, English isn't my primary language so I don't know all the technical terminology. So I ended up owning this PS4 slim that had a problem pairing controller. Once opened, I removed the WiFi chip and some joint ended up like in photo (I don't know the technical terms, if you could tell me how it's called I'll appreciate). How can I fix this?... -
