no it doesn't work, the phone need to be detected by the computer.
The problem is the cpu
Stop advertising for a shit .... bought two times Tenorshare products ... are garbage. Tried on 5 smartphones Reiboot NOTHING WORKED ... they do not refund money
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 !!!❤
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. 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
and succeeded???
como supiste q estaba al 100 a mi no me sale ni q carga
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.
What temperature did you use
I disconnected all cameras and removed them to be safe side 😅.
My phone restarts itself ,can this help
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.
(I am French) This reflow still works for you?
@@aloncle je me pose la même question
@@aloncle Yes. The phone is kept as a spare now.
@@dfor50lol 10 months later still works ?
great work bro thanks you solved my problem ❤
super,,all is functional.tHANKS
عملت بشكل ممتاز بعد المرة الثالة , شكرا لك
worked after the third trial , thanks
It worked. Thank you!
thank you sir it works i dont know for how long ..... but IT WORKS!
Is the device working now??
@@mahmoudhamed5807 after 2 months it starts the same problem again.
Did you lose your data after that?
Cant believe this worked!! Thank u !
الله يوفقك فيديو في المستوى حليت بيه مشكل هاتف A51 دائما لوح الجديد
سلام عليكم اخوية صارت عندي نفس المشكلة ممكن تساعدني
ممكن جاوبني
@@jj_1_zz هل وجدت حل
Thanks buddy I'll try this method
Gracias buen hombre se merece un 5 estrellas me salvaste la informacion ........un nuevo suscriptor.....
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 TH-cam for that part)
THANKS SO MUCH EXPERT!!
Thank you man i love u
this wroks, thnks bro👌
It worked . Thanks a lot ❤
Thank you, was able to get my phone to restart ,didn't have to go get a new one
How long did it work afterwards ,

Thanks Bro❤❤
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
thank you my phone problom solved bro
bang , apakah karena ini ( memori kepenuhan , kebanyakan applikasi , kebanyakan data) bisa mengakibatkan mati total setelah kita merestart ulang kembali ? (padahal ramnya 8 dan 128 GB )soalnya hp saya tdk pernah jatuh, tidak pernah tertindih , tdk pernah terkena air tapi tiba tiba mati total setelah merestart ulang kembali , cara mencegah dan solusinya bagaimana yaa bang , bantu di jawab yaa bang terima kasih
Thank you very much!
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
How to lower the memory???
THANKS MY TEACHER .DONE
Gonna try this and comment if it worked in a few hours.
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
Worked❤
good job
my phone is charging and when i turn it on it stuck on logo then screen goes blank but when i plug the phone i can hear charging sound i can go to recovery mode and download phone i tried flash software but still the same problem.
so could be the problem like ur dvice?
It wwound better if you gave an explanation of what you are doing and why
Quando isso acontece perde todas as confirmações do cell? Digo, arquivos fotos e tudo mais?
😭 Vous avez sauvé le téléphone de ma fille avec toutes ses photos... je vous remercie du fond du coeur. Merci pour votre travail exceptionnel. ❤
Better back up the stuff quick , reflow is usually considered a temporary fix. Whatever that bad solder joint might occur again
Thank you.
Supper bro
How many degrees? Thank you
Will give this a go as last resort dont want to melt stuff my heat gun is for stripping paint its big and bulky
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
Sir apki shop kidr hai smae yahi issue mra model ka sat ha same model
Is they a chip u need to replace

مرحبا عندي نفس التلفون ونفس المشكلة وديته مصلح هندي بالبحرين قالي ال ic momery خربان شو المشكلة بتكون
What type of tool did he use to heat up the components?
جوالي نفس المشكله هل يرجع يشتغل بشكل دايم ولاماله حل؟؟
اخوي مشان الله هاتفي طفي نفس المشكلة او نفس الهاتف بس ال samsung الصغير ما يحطهة بس يرج او يرجع يعيد شو الحل صحي المعالج خربان 🤔
أخي أنا تليفوني نفس المشكلة ...هل انشيله لصيانة علي طول
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.
How did u update?
I thought it's a software issue because this happened after I downloaded something
samsung a51 turns on, works for 1 minute, but keeps resetting, I installed software, it still didn't fix
That phone hace the problem of loop in the logo?
Cuz i have the same problem:c
السلام عليكم ، عيدك مبارك مقدما
عندي مشكلة بيدة ال ps4. واتمنى منك تنصحني فيها.
اليده تبعي تنضغط زر ال PS الي هو الباور تلقائيا في فترات معينه.
جربت فكيت اليده وازلت تماما الزر والربل الي يضغطه ، واضغطها يدويا عند الاستخدام بواسطة قلم الصقت الربله فيه .
مع ذلك بعد اسبوع رجعت من جديد تنضغط رغم انه مافي اي شي فوق رقاقة الزر ، يعني لا الزر الخارجي الي هو Ps. ولا الربله البيضاء الي تضعط ع رقاقة الزر .
هل في طريقه اعالج المشكله هذي
Change a new controller nappe (the green mother board paper thing)
RECOMEDADO! este tip para este tipo de modelo de samsung.
Hi sir.. Is this temparvry saliution..? Pls reply
Hello. How many degrees centigrade Is the setup of your heat gun? Regards.
@@K7ABIIR Thank you.
إذا سويت فورمات تضبط؟
Same problem with my Samsung A51 always auto restart .please help
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 with my phone did you get it fixed?
worked
السلام عليكم يعطيك العافيه اغلبك بدي اتواصل معك لو سمحت انا في الاردن
معيا نفس التلفون عندي مشكله انو بيعد يرستر لوحدو و انا بستغدمو و بيعمل الحركه ده كتير و جربت اعمل الضبط بل زرار البور و الصوت منفعش مش عيزه تيجي
إطفي الجهاز خالص و بعدين وصله بالكمبيوتر و بعدين شوية إضغط على زر الباور و زر رفع الصوت
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
من فضلك حل المشكله تسخين فقط ام تغيير شيء بقطعه جديده
لو سمحت يا غالي السلك الأصفر السادس فى سماعات الايفون جبته منين فى فيديو تحويل من مدخل لايتنج الي مدخل 3.5 ملي
i have the same prob it didn't work for me it's still stuck rebooting maybe i didnt heat it enough. ps: i tried with the hair dryer
Nesesitas calentarlo entre 250 centígrados.
