Thanks for the heads up where the issue is. Here’s my version: Have A51 on my desk for this same problem. Device pulls full amps when powered down and charging battery. Upon prompt to boot, device would go to Samsung “A51” logo and amp draw would drop to .38 amps on high powered USBC charger. No amp fluctuation at all. Solid .38 and solid logo that only goes away when battery dies off charger. Saw your video, so i pulled the board and then removed the sticker/shield. Found two underfilled chips and one large chip without underfill. Reflowed the large chip with steady low heat (300 c) carefully avoiding the underfilled chips. (No solder balls). Upon reassembly I now have boot! (Booted to pass screen). My guess is this won’t be a permanent solution and reball at least will be necessary. Getting passcode from customer for data before I move forward. Thanks for the tutorial and happy fixing!
thanks for sharing, it works! i didnt heat the USB part though which i suspect mainly the IC smd solder has been loosen. Keep it up on the good work. If you lack of the heat gun for soldering to heat up the chip, you also can use normal heat gun. But the most important is you need shield the camera part to avoid damaging it.
It actually worked like a champ. I used a regular heat gun and just tried to shield as much as I could. I also used a thermometer to make sure I wasn't going over 300°
Спасибо огромное. Все получилось. Но не с первого раза . Сначала пробовал просто прогреть , без изменений. Потом прогрел эту плату с обеих сторон- опять нет результата. Потоп прогрел 3 раза . И почистил нижнюю плату очистителем контактов Liqui moly electronic spray. Начала показывать зарядка при подключении к пк. Сначала включилась опять эта заставка - перезагрузил на звук минус и кнопку включения . И через минуту телефон запустился ! Ура ! До последнего не надеялся на успех ! Спасибо автору !!!❤
This instruction helped me fix a relatives A51. I have had some experience with reflows to laptops but I'd never done it with a phone. The professional phone shop was clueless but now we've got all the information off it that we needed. I feel a reflow like this is a temporary fix as it is with laptops but it did the job for now. Thank you EXPERT.
👍👍J’ai fait la même chose sur un Samsung Galaxy A50 qui avait le même problème j’ai tout démonté tout nettoyé et ça refonctionne maintenant. 👍👍 👍👍Combien de temps je ne sais pas, j’ai dit aux propriétaires un ami de récupérer toutes les données au cas où ça recommence👍👍
I tried heating the side shown in the clip but it didnt work. the 2nd time i tried the other side. and the 3rd time the original side again. each time with a standard 300 degC heat gun at a greater distance than shown (maybe 15cm) for ~40 seconds each time. Leave to cool undisturbed for several minutes each time too. Note: Remove ALL cameras from the motherboard and direct heat to the main covered shielded (Alu cap) areas on each side. (i used spare loose heat gun nozzles to mask and protect the other PCB component areas whilst doing it.) Finally i fitted it back together again and recharged the phone fully, then did the vol down + power button to restart then volume up with power button to reset the system cache in recovery menu, then reboot, all whilst connected to a laptop USB port. (initially it looked like it was still locked in the boot screen) after a while i saw the 'UI apps optimising' message before a full restart. I have managed to recover my files! Other people may want to perservere with the vol button options after the heating, plenty of tutorials on UA-cam for that part) THANKS SO MUCH EXPERT!!
Esa solución es solo momentánea le va a funcionar unos días nada más y se va a volver a quedar en el logo lo ideal es bajar la memoria y hacerle reballing
Hii sir same problem I am facing from my phone a51 what should I do plz say sir i had important data in that please say solution sir i beg your pardon😭😭
Probably iust better to go to a shop and ask to do a reflow , but If you think you can do this, buy yourself a hot air station with adjustable temp plus air , you can get one for around 45 bucks and I'm sure a reflow at a shop will cost similar but if it works you will have a jot air station and a working phone , well kinda or if it doesn't, you will still have a hot air station. But then again a reball is the actual fix if its bad solder connections under the bga chip
@@manueljuarez9985 y como sabes que esta a esa temperatura? lo unico que tengo que llega esa temp es el secador, medio jugado pero ya me tiene mal que se tilda a cada rato y se reinicia solo y despues no pasa del logo
A problem I have in addition to this it seems is that the phone registers as charging, but in reality the battery just drains as it is charging. All the way to 0%. Any solution for this?
same problem .i checked my mbil to technition they changed charging ic. and said if this will not work mother board will be replaced cost around 13 thousand😐plz tell me they are saying right or not. m in trouble now

C'est exactement comme dans la vidéo ce qui m'arrive en ce moment, j'ai essayé d'ouvrir l'appareil mais impossible, je n'ai pas les outils pour ça. J'ai lu que c'est à cause d'une mise à jour non installé, de plus la mémoire de mon téléphone est presque pleine. Les messages n'arrêtais pas de me proposer la mise à jour du logiciel et de vider la mémoire. Par la même occasion j'ai eu droit à un virus, mais je ne sais pas s'il s'est installé.
Mon problème est résolu, j'ai pu faire la mise à jour, installé des antivirus pour voir si j'avais vraiment un virus. Et bien pas de virus, j'ai donc désinstallé les antivirus et bloqué la sauvegarde de mes photos. Par contre la batterie surchauffe à des moments. Je verrai par la suite s'il faut la changer.

I bring my phone to the shop and they exactly do the same and it worked. When I got home, my phone won't start and keeps the logo stuck. What should I do?
For me too after the second attempt. I just redid the steps and it worked again. I assume something was loose. I heated it with a 300°C fan if it helps.

Better back up the stuff quick , reflow is usually considered a temporary fix. Whatever that bad solder joint might occur again
Is they a chip u need to replace

probably oil
It is glued

the part you heat up on the board is what? and what are benefits of doing so?
it's rehot, heating certain ic components aiming to make the legs of the ic stick perfectly again. looks like it's part ic ram / ups
Will give this a go as last resort dont want to melt stuff my heat gun is for stripping paint its big and bulky
