My Note 8 Had a Bootloop then never turned on / charged [PLEASE HELP]

[johnmark21t]

Hi Guys this is my first time posting here and hoping to find a solution to what I'm experiencing right now.

This is actually the second time and what happened is that my phone got into a BOOTLOOP so of course, Ideally the first thing I did was to forced it to shutdown using the Volume down + Power button combination and so I did, the phone turned off, But after that, When I tried to turned it on again, it won't turn itself on. I even tried to hold various button combinations but to no avail, nothing worked. Aside from that, I have tried to plug in the charger periodically after 20 - 30 seconds with the same interval before plugging it out and repeated the cycle for 20 tries but same result, it didn't worked as well..

So I'm here hoping that someone will be able to help me out as I don't know what to do anymore and I badly need to use my phone for my studies as well.. :crying::crying:

Hello @johnmark21t, I will do my best to help you to figure out what's going wrong with your Note8

Have you tried to boot into download mode (volume down + Bixby + power button) ? Does it work or not ?

If you can't boot your device into Recovery Mode then the motherboard is fried. You are better off getting a new device rather than replacing the motherboard

Yes I do have tried it but nothing happened or no response at all..

That's what I'm also thinking about but I cannot comprehend as to why it became like this as my phone was just on standby mode and then just turned off by itself and by the time that it restarted, it was stucked on the Samsung logo in which after I saw that it was like that, I have forced restarted it so I think that's my last conclusion but I don't think that that is the case for me...

What rom and what kernel you have what modes?. What twrp you have? You have flash wrong rom? Wrong kernel? Is impossible for the phone to turn in boot loop mode itself. You did something wrong before the bootloop. Try volume up and Bixby and power button for 30 secs. Or volume down and Bixby and power button for 30 secs. Motherboard failure no give you boot loop. Give you blue screen. Try to flah with Odin is the easy way.

Unfortunately I'm only at stock, not even rooted and I don't have custom recovery mode installed.. all in stock. Even the Odin mode is inaccessible as well.. and again I didn't do anything prior before this happened..

Try connecting your device to a computer with Smartswitch installed and run the emergency recovery process. If that doesn't work then I would recommend that you take your device to a Samsung Service Center and let them take a look at it.

However you should be able to repair your issues using Smartswitch.

Download and install Smartswitch onto your computer. Then connect your device to your computer and launch Smartswitch. If your device is detected by Smartswitch then launch the Emergency Recovery Process.

I'd like to dig this topic out.

I'm also experiencing bootloop after latest OTA update. I've taken device to Samsung Service and they told me that it's faulty motherboard and they want to charge me 1300pln which is about 335$ so I'm like - Hell no, it's not worth it.

Anyway, I'm kind of sceptical about whole fried motherboard story, since recovery mode is working correctly, download mode is showing up as well. I tried to flash same firmware as it has now. It passed but result is the same.
Gonna download some older SW version and try again but maybe any other suggestions from you guys?

UPDATE: Older SW version downloaded and result is still the same. So yeah, screw it

Try flashing firmware that's at least one update above the version you have on the phone and after you flash it in Odin and it finishes with a "PASS" then go into recovery mode and do a factory reset in fact try doing a factory reset right now just to see if it'll work since you have nothing to lose at this point.

Have you got the Samsung drivers installed on your computer?

I had a similar issue with my note 8. Just today . My phone carrier sent me an update (from USA T-Mobile ) to install. I had my phone connected to power .. and Phone just died during the update . I wonder if motherboard got fried ...

 

[Kamikazzi]

Same issue

UPDATE: Older SW version downloaded and result is still the same. So yeah, screw it

Any update on your phone?

I hope there's a class-action lawsuit about this. My Note8 had the same problem. An OTA update was done, and the phone shut off, never to turn on again. No combination of buttons powered the phone on at all.

Maybe it's a panic mode, just keep connected to wall charger for a while, then hold all 4 keys to force device to restart
