Samsung A51 (A515F) Stuck on logo/Auto restart solution FIX FULL GUIDE 

الله يوفقك فيديو في المستوى حليت بيه مشكل هاتف A51 دائما لوح الجديد

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!

thank you sir it works i dont know for how long ..... but IT WORKS!

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 RU-vid for that part) THANKS SO MUCH EXPERT!!

Thank you, was able to get my phone to restart ,didn't have to go get a new one

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😭😭

It worked . Thanks a lot ❤

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?

All fine, Thank You, , But why there is no sound , no explanation,,,, why ??

جهاز سخيف لاانصح به👎🏻👎🏻👎🏻👎🏻

it`s not a repair! just temporary solutin to call your Ma and say: I got a problem with my phone!

number kisi meli ga

My phone is not start using this process

طريقه فاشله وره مده هم يرجع يعلق

not working for my phone

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.

You sir, are a GOD among men!! Tried this on my A53 5G and it worked! Many thanks for your wisdom.

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

THANK YO BROOOO MY BROTHER IS DUMB, AND HE CANT REPAIR HIS PHONE. THX TOO MUCH

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°

My man, may god grant you eternal life, i was skeptical first but now i have a working A51, may u have eternal happy days

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 !!!❤

Thank you. It works! I did the exact same twice. The first time didn‘t work. The second time I ensured that the battery is 100% before starting it

عملت بشكل ممتاز بعد المرة الثالة , شكرا لك worked after the third trial , thanks

yeah im not doing all that

Gonna try this and comment if it worked in a few hours.

جوالي نفس المشكله هل يرجع يشتغل بشكل دايم ولاماله حل؟؟

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.

اخي عندي نفس المشكله لمن اشعل الجهاز يظهر لي خط ابيظ ع الشاشه وعلامه الشحن ولمن اظغط ع زر الباور مع الصوت يظهر لي علامه سامسونج بعدين يطفى

السلام عليكم ورحمة الله وبركاته لوسمحت تقول لي كيف اعالج جوالي توقف على شعار سامسونج قبل كذا تخلت ماء بعدها بيومين توقف اريد الحل بدون فرمت وبدون حذف البيانات
