And you my friend are a genius with a heat gun! I fixed my SAMSUNG S7 ACTIVE from a dead phone into working again, I did not take apart the housing for the processor on the board, I only applied heat for 10 seconds or less until very hot and then put it back together, it worked. These processors sometimes need a little refreshing. Amazing! Thank you so much! I will be studying on learning how to reflow laptops I have two right now needing it. I also bought a multimeter so I can learn more about current and help diagnose better! Congrats! I truly appreciate it!
I did the same today - and it worked also - i had pulled the phone s7 edge from a PC while it was reading a picture and charging - it tried to restart then had fixed blue light - no response - i left it to die- took like a month - swapped the battery but still no response - i saw this and used my hot air until the solder melted as i touched the big cap next to the chip and it moved a little bit - that was enough - and to my amazement - it now works again - thank u so much -
took the board off and fixed it with a 2300w hairdryer for 60s !!!! Thank you sooooooooo much The repair guy said it's CPU's problem and can't be fixed lol
God bless you mate. I just fix my S7 by your way. Even i was in couple of repair shops and the refuse to fix it because is old and not worth it. I use normal heating soldering iron. I know that is risky and not correct because had risk of overheating but exactly that helps. Before to try this the phone just freeze on the logo. Now everything works. Big respect for your job man 🍺🍻
@@VKEDITZKBFC Its better to invest in heat gun. I actually just touch each chip for 3 seconds with the soldering and leave it to cold. Is very risky. You can kill it forever. Be careful because you can overheat it very easy. But i dont think this is enough. Because i have the same problem again. The phone works for 3 days and this happened again. Fortunately that was enough to download all of my data. After that i just bought new phone.
When device sometimes has message screen saying installing system update, bypass it by pressing and holding power button until the device powers on. Hope this helps for future reference.
What hot air temperature do you use and how much air flow? I'm struggling to resolder chips using 350 C or 375 C. I takes me more than a minute to get them moving. In your video it takes few seconds, what's the magic?
Hello. Just wondering if you had a suggestion on how to do this on an A5. The metal part seems to be soldered to the board! Would applying heat through the metal cover work? Thanks!
How did you reattach the RF Shield that you removed at 2:30? What about the back cover, just use heat to reflow the original adhesive? I see lots of disassembly guides but few have the reassembly part. Thanks!
Hi, this is my first time using soldering iron. do I need the (hot air station)? can i use JUST the soldering iron instead of gun iron? if yes, how can I use soldering iron because it is my first time, so do i need to let the iron touch the surface or on the air to melt the Rosin Paste, and for how long? do i need to let the soldering iron heat for how long before using it?
What if the phone boots with a new battery that has been charged, but doesn't want to charge with cable and too and wireless charging doesn't work. The phone doesn't want to charge. It was working to charge wireless before some days but very very slow 16 hours for 100%. Now and wireless doesn't work anymore. Where is the problem? In the charging port or in the chips showed in the video?
I have a Galaxy S7 doing the same thing not coming on my the charging circuit board getting very hot do you think it's going out it does not come on at all

Hallo being watching and loving your channel , I just have a question what is the hot air temperature you use on your phone PCB ? sometimes I get Ic's on the other side of the board that the solder would bubble out on the sides killing the phone I use 400 degree in my quick850
hi .. the part that you just fixet on motherboard,on my phone get very hot wen i put on charger .what is that solution that you uset? or what should i do?
My Galaxy s7 were dead after stuck, When the dead my phone it was heated mostly. I give to a local phone rapair shop to repair it. They said that" Power ic damaged & mother board must be replaced" Is it possible to repair with outreplacing mother board? Please help me
Hello I just have done this operation. But now this zone became super hot after few seconds when I plug the charger. What can be happened? I have 1.95Volt at battery PINs (the phone don't turn on). Thanks
My phone is dead as well. I changed the battery but seems the problem is in the motherboard. When I changed the battery a plugged in the charger and the second component right next to the one you soldered is very hot. Seems there is the problem. What is it?
I just tried to repair my phone and destroyed it even more. My heat gun takes alot of time (on 360 oC) until chip is unsoldered and I have pressed too much on chip and squeeze tin below the chip outside.
Can I ask you something please? My Samsung 7 died. It will charge, but it will not turn on. The repair shop said it was the motherboard. I already bought a new phone. It is a Samsung 20fe. I kept the same phone number and the same carrier Rogers. What my problem is is that I lost access to my UA-cam channel through my phone because I never wrote down the UA-cam channel password or email, so I cannot get on to my UA-cam channel without the direct access that I get from it through my phone. Question is: if I fix my motherboard and put in my new SIM card from my new phone will I again have access to my UA-cam channel? I did make a new channel, but I still want the old one back and am willing to pay money to do so despite my channel being lame and not a money maker.
After I followed your steps the camera flash started firing for a couple of seconds and then turned off again but the phone is still in dead condition. any solution? thanks
@@MCH92 Honestly sounds like you heated the board too much and bridged one of the solder connections underneath the BGA, hence creating a short on the motherboard.
When i did this fix and plugged the charger in, my flashlight started blinking and my power supply got super hot. Do you think this phone is a lost cause or is it possible to fix with some magic?
Great videos, very educational. I have tried this on my water damaged s7 but no luck. What would be the next thing to do other than throw it in the bin? Thanks, made my own flux from watching your videos.

Put some metal on top and heat it with iron.
all I had was a heat gun and just heated it up nicely and it powered up, I'm still dumbfounded, you are the man
no resin or flux needed? heat it up until it the chip moves and then let it cool back down?
