Black screen and blue led please help - Samsung Galaxy S7 Edge Questions and Answers

Hello everyone !
I wanted to update my Galaxy s7 Edge in version 7.0 and everything went well and at the time of reboot the phone just started to show the S of SAMSUNG then it has frozen, then black screen and Blue led on.
Unable to go back in download mode the phone no longer responds to anything, but I do nothing but nothing.
When I connect it to the PC nothing happens.
Would you have an idea how to switch to download mode or other?

What did you do? Seems you flashed a wrong bootloader. If so you're out of luck and can use it as paperweight.

No !
I have flashed this firmware G935FXXU1DPLT_G935FOXA1DPLT_BTU
Download from sammobile !

Can you send me the link you flashed??
If you can't goto download try recovery mode....if you can't access either of them then your only option is to goto a samsung store and tell them your device went blank after an update that it got hanged don't tell them you flashed it via pc

Can you also provide more details like what happens when you restart it now?
Can you still see the Samsung logo show up when u restart......

Thanks for the reply,
no I can no longer see the samsung logo, I have a black and blue led display.
To flasher is what it is necessary to activate the debug usb and activate OEM
I do not have access to these options since the phone does not turn on?
Thank you !

Which phone version do you have exactly? (the last letter after the model - 935)
Anyways, as stated I guess the bootloader is damaged and this is something only Samsung can repair. However, the chances are towards zero that this happens during normal operations so they may refuse to help.

Same problem
I had the same problem. I left the phone on for 24 hours finally the blue light went off indicating that the system was off. I waited another 2 hours and then put it on the charger. Once the charging icon came on, I put the phone in download mode. This finally got it up again.

Do this leave your phone on to die out completely make sure the battery is completely dead then put it for charging leave it for 4hours and try turning it on....
If that doesn't work goto where you purchased it and tell them after the update your phone won't start don't tell them you flashed it via pc

Try this:
1. Hold Volume down
2. Hold home button
3. Hold power button all at the same time but in this order. And keep holding it for at least 20 seconds. It should get out of that blue light loop and eventually go to download mode. Also make sure that when You're doing it, the phone is unplugged from the computer or a charger.

Here's my story:
On 6.0.1 my flat S7 used to reboot like every other hour and have black screen problem. A forced reboot fixed it every time. I soft and hard reset it but no gain. As I made my mind of getting rid of it, I got Nougat update. I updated it hoping it'd fix it and it did. For nearly 2 weeks there was no reboot, no problem. Yesterday it just died, black screen and blue LED exactly how the OP says. Forced reboot doesn't work anymore, no combintion works, charging doesn't help, PC doesn't recognize it etc. I've run out of options.

I flash with odin and the flash goes well and full and reboot the phone does not start.
Arrived at the samsung logo it only displays the S then it freezes then reboot then there is a black screen and the blue led on and nothing works any button nor download mode nor recovery nor anything.
It is necessary to wait all night that the battery is discharged then I can repeat the procedure.
I tried official roms marshmallow it does not work, I tried official roms nougat it does not work. It all passes succes with odin but does not restart the phone.
I upgraded with Kies and all is well to go until the end but the restart of the phone freezes to the logo samsung.
Where can the problem come from since all the flash goes very well.
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Je flash avec odin et le flash se passe bien et complet et au reboot le téléphone ne démarre pas.
Arrivé au logo samsung il n'affiche que le S puis il fige puis reboot ensuite il y a un ecran noir et la led bleu allumé et plus rien ne marche aucun bouton ni mode download ni recovery ni rien.
Il faut attendre toute la nuit que la batterie se décharge ensuite je peux refaire la procedure.
j'ai essayé des rom officielles marshmallow ça ne marche pas, j'ai essayé des rom officielles nougat ça ne marche pas. Elle passe toutes avec succès avec odin mais pas de redémarrage du téléphone.
J'ai mis à jour avec Kies et tout c'est bien passer jusqu'à la fin mais au redemarrage du téléphone il fige au logo samsung.
D'où peut venir le problème puisque tous les flash se passe très bien.

Did you leave it for over 24 hours WITHOUT CHARGE so that the battery would completely discharge? The blue led will turn off once it has discharged and then wait an additional 4 hours.

Yeah did so. I read it here so did that. It turned on, worked fine. I restarted. Got stuck at S of Samsung logo again. Tried 4 hour solution again. It worked again. Rebooted. Kept working cool. Thought it was over. So thought of resetting to set up the device from scratch. I pressed reset and the phone never came back.
Took it yesterday to store. They flashed the software. Worked for like 10 minutes and then died. After a couple of hours of testing, they said it was motherboard which was faulty and it'll take two to three days to replace that. I'll probably check with them on Friday now.

[Q] CyanogenMod9 Bootload Gingerbread

Hey Guys
I recently installed the CyanogenMod9 for my DACH-Retailversion of my Milestone 2. Installation was Succesfull, but when i boot my phone, the Red M-Logo comes, and then the CyanogenMod starts. All no Problem, but i get a bootloop while starting the CyanogenMod. The 9 appears, and then the CyanogenMod Logo appears, and then it starts again (9 appears, CyanogenMod Logo appears) and again and again..
I want to flash my Milestone with RSD-Lite, but it doesn't recognize my Cellphone. Two weaks ago, i had the problem with the M-Logo and it worked, but now, it doesn't work anymore..
What can I do now?

(Sorry for my bad English, I'm German)
Try entering the Stock Recovery and select the 'wipe all data' or something like that and see if your phone starts normally after that

Flash the fixed sbf from the first post in the cyanogen mod 7 thread
Or at least I think there's one.. I'm off to bed anyway
But yeah I think you must have used the wrong version (one is for people who updated to official gingerbread, and the other is for everyone who didn't update).
Using the wrong one will cause a boot loop until you get the right kernel on it (ie flash fixed sbf)

Hi

Auto reboot in Fastboot/Recovery/EDL

Suddenly my Note 7 lagged on lock screen and started to go in to a bootloop. 5 seconds window, then reboot continuously.
Tried accessing Recovery and Fastboot modes. But it also reboots automatically again in 5 seconds. happened for the last 24 hours now.
Then I decided to solve this through EDL test point method. It does detected by PC as Qualcomm device then disconnects in 10 seconds.
Phone was in MMX Stable 12.0.1 rom / Rooted / BL unlocked. No mods and light use without gaming at all.
I found not more than 3 threads in XDA/Telegram/Reddit regarding same issue and neither had a solution.
Does anyone know a solution for this?
Thanks in advance!
Anyone?
bonsoir,decompresse ta rom extrait le recovery et reflash le...dis moi si ca marche...
