Great video! So if I understand correctly, you have resoldered the U9005 and U9010 chips? And this fixed the phone? I have a completely dead Galaxy S7 Edge. I can not access data. Samsung service guys told me the motherboard is dead but not specifically which part of the motherboard is dead. I would really like to salvage data. Do you think resoldering like you did it will fix my phone?
Ive had some kind of problem with every Samsung I ever owned, my last two were brand new S7's and they both just died randomly, one in under a year, the other in about 2....I really liked the S7, perfect size and with everything I really needed in a phone but no more money for Sammy until I die, that is my promise. I don't expect other brands to be any better but they can all be had at a fraction of the price, "flagship" priced phones are another suckers game.
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?
Hello,i thing you should watch all the training courses that we ve got on MovilOne RUclips channel, about microsoldering; it should help you! Best regards
@@MovilonePhoneRepair I don't have a microscope, can't I use normal soldering iron? did you change the malfunctioning ICs? and how did you apply the DC power to test the phone when the battery was removed? Thanks alot!
Wow... so this could be it. My S7 just flat out died and dont start in any way. Completely dead. I just changed the battery, and it didnt solve the problem :( But resoldering these chips then... It will be the last try. My S7 died after ca 3.5 years of daily use. The screen froze while I was surfing the web, and I turned it off, after that it has never made any life signs no matter how I press the buttons. I have soldering skills so im gonna attempt this with my heatgun.
@@MovilonePhoneRepair so what do you think i should do? what procedures should i take first? and if it is a memory problem, what is the solution? thanks in advance
Could you take the same parts off a working USA motherboard and put it onto a UK motherboard to fix this problem, only asking as I bought a motherboard off Ebay that only works in America.
Mine is dead as well and I haven't tried to repair it yet. I thought it's a battery fault, but when I opened the phone and plugged it in for charging, the motherboard is overheating in this area, but mostly in the next component to the right, next to the one, which you removed the metal cover. My phone is still covered by warranty, but I am confused what to do cause I don't want to lose my data and maybe I will attempt a repair.
If it is covered by the warranty, it would be advisable to take it, but if it is already open, I doubt that you will be taken care ... this samsung series has come out quite problematic...
@@MovilonePhoneRepair I can purchase an adhesive and it will be fine. Still, when I asked them if it's gonna be repaired they said that they won't and if they do not manage to get it working which they will not, since it's a motherboard issue, it will be destroyed and I would get a refund or a similar class phone. It worked perfectly fine, but when I attempted fast charging , it fucked up.
@@StoneTL No, I haven't tried yet. I do not live in my native country and I do not have soldering equipment yet. That component is the processor I think. Mine problem happened when I used samsung fast chargin adapter and it started fast charging since it is set up in the factory settings to attempt fast chargig when you use that type of adapter.
Hi, i have a water damaged Samsung galaxy j6 and it's motherboard is dead, is it possible to fix a dead motherboard and make it work again? Here the local repairers said that you have to change the motherboard but I know they are not that much experts. Kindly reply me with the best solution to make the same motherboard work. Thanks for the video
sir i have a question my board is totally damage and the technician said that he will replace it with new one i have a question there is it possible that my installed apps will be intact if i were too replace it with new one thank you i hope you'll reply :)
Johnny Mac Better to never use samsung again... my s7 is dead too. in this video they didn't fix anything. They just changed the motherborad (wich is very hard to find today). My advice : never buy any flagship again... why ??? because these are powerhorses that needs a thermal dissipation wich the glass on the back is very harmfull and avoid cooling the motherboard ! Better to use top mid-range and save your money next time !
You need to heat the back up and then use a pry tool, blade or plastic razor blade to slide in between the edge of the case and the back. Dont try to pull the back off as you will snap it, instead push the blade inside and work it along the edge of the frame, there is a 3mm sticky seal that you are separating between the frame and the rear casing. you can push the blade into the case as far as you like and wont damage anything as the PCB is protected under covers so you wont rip any components off the board. nothing is acessable untill those covers are removed so you are safe to get stuck in there and separate the casing glue

totally agree with you. Mine gf's S7 edge just died. Now I thinking a buying A51. Hate new phones. All of this punch wholes or U V shape camera notches oh Lord. S10e battery way to weak with 3100 or 3400 for S10 and price tags $500-700 nagh. Defiantly $300 is the limit. Gonna do the same with flux and soldering iron. Just to recover data.
Any Idea how many millions of these phones were sold? I'd guess the reliability MTBF is approaching 100,000 hours. Your bad experience is a tiny fraction of the in service units, so no, you'd have the same chances if you had an iPhone, LG, Sony or Huawei.
I have a completely dead S7 edge and a S7 (not edge) with broken screen but comes on and plays tune. Are the motherboards interchangeable? The edge screen is good.
Yes, you can swap the motherboards between Samsung S7's of the same type ie Edge into an edge. I have done this several times as it is often much cheaper to get an unused S7 or a lightly used one and swap the motherboards over to save having to mess about changing the broken screen. same with the cameras, the charging port and the headphone jack.
A BIG THANKS for the great video! How did you know it is the IC (U9005, U9010) OR the USB charging port? Should I check the ICs if they are heating? I have S7 which does not start, does take 0,22A from power supply and does not show display.
The root cause was most probably dry joint in the solder due to thermal stresses. He added Flux and heated the area to melt and re-flow the solder between the contact pads on the circuit board and the component terminals. Does that answer your question?
I dropped my phone and it bounced two or three times on the ground. No problem,still working. But that night i made a reset to factory settings and turn it Off. Next morning I could not turn it On anymore. What do you think?
hi my s7 was working fine (i did get a battery performance warning occasionally). i was watching a video on fb and it froze and went off. now wont charge or turn on. this process what is the fault:? my phone can if i fit with a new battery you think it will work or is it this fault
Hola, Zabdiel! Segun el coste del repuesto, pero...eche un vistazo por encima con los provedores con cual trabajamos a nivel nacional y no hemos encontrado el repuesto...asi que, te animamos que lo busques en Aliexpress o eBay! Un saludo cordial u gracias por preguntar
I had the same issue with my s7 after this, I just grasped the phone with my hands and tried to twist and bend it in half. Then after I did that it booted up.
I used 350 degree and heated the chips up for 4 minutes. Nothing happened. Then I increased to 480 and still nothing happened. I was not able to move the chips. The solder did not seem to melt.
350-400 Degrees Celsius and you need the flux paste. iI you don't have flux paste then it wont work regardless of how hot you get it. if using an air station, 350 degrees at 25% air should do the trick. When using the flux paste / gel you can get no clean and stuff you have to clean off. i would recommend getting the no clean as you will need to buy the cleaner and an ultrasonic bath if its the residue stuff. if you dont clean that stuff off it will rot the board as its slightly corrosive
@@MovilonePhoneRepair My s7 keep restarting every 30 sec and i tried hard reset ,factory reset and safe mode. Nothing helps the iphons. is there any fix?
wouldn't it be cheaper to buy a new phone ? The equipment alone to fix this, including the microscope he is using probably costs a couple thousand dollars.
You obviously don't need the microscope (unless you're making a video) and if you don't already have a soldering iron ($40) you probably shouldn't consider making this kind of repair anyway.
I dropped my phone and it bounced two or three times on the ground. After that, everything is ok, still working! But that night i made a reset to factory settings and turn it Off. Next morning I could not turn it On anymore. What do you think?
