S8 Stuck in Download Mode / Boot Mode. - Samsung Galaxy S8 Questions and Answers

Hey guys,
So I was on lunch break and left my phone on the cup holder and all of sudden I looked at my phone and it was in boot mode so I tried to reset it so I could use it, but I wasn't able to press any of the buttons to choose the options. Yet I was able to hold my power and volume button to turn it off but it would just come right back to the boot mode. After messing around with it a bit more I was able to get it into download mode by holding bixby, power, and the volume button, but the same thing still happened I wasn't able to select any of the options. I've tried putting my phone into safe mode when my phone died, but it would just send me straight to the boot mode. What I remember was that I had a system update at the time and I pretty much kept ignoring it and trying to find a way to bypass it so that I wouldn't be require to keep doing the system update. I was searching other threads to find my issue but it doesn't seem like no one's ran into this issue yet, or I just haven't come across it yet. I'm just trying to factory reset my phone at this point haha.
Thanks!

Did you try flashing using odin?

The problem is when I exit the odin apps or reset or pull out the cord and put it back in it wont detect the phone. so I need to off the mobile again and charge it til it powers on after 4 hours of charging. thats my problem, and that serial(com)ports problem pops up.

Did you mean that Odin don't recognize any com port?? Or that the PC don't recognize your device??
Remember u need the Samsung drivers installed so u can properly flash with odin.
Take a look at windows device manager, connect your phone and see what happened, in the USB check for Samsung USB composite device, or see if at least any new hardware is detected, and the window blinks a couple of times.

You should install Samsung USB drivers, just search on google Samsung USB Drivers. Then try to flash again. Hope you get that fixed.

[Q] how do you know if you have a vibrant that cant boot to download mode?

OK i have the t-mobile vibrant my second one. for the reason the first one would not take charge or died to quick or something. The thing is i flash vibrant7 flash OK but it was freezing so i made a nandroid of stock rooted vibrant so i can flash back to. So on the proses of nanrestoring it finish and rebooted but it got stock on the vibrant screen not booting up. so i tried going into download mode but no good tried every single button combination no good. so am asking how would you know if you have one of those vibrant that cant boot to download mode. also i cant access
adb for the reason it doesn't reconices the device. help!!!!!!
Plug your phone into you computer via usb while its off, wait for the battery charging icon to appear. HOLD PWR+VOL-UP+VOL-DOWN until the screen goes black, then RELEASE POWER, but continue to HOLD both VOL buttons. That should boot you into download mode NP

Sorry to those members who may get angry by me posting on the dev section i thought i was on the general section. but that did not help thank you!!! very much for posting.
make sure you have the Samsung drivers installed for your phone, you can find both 32bit and 64 bit drivers floating around
boot your phone into stock recovery
now plug your phone into your computer
go to adb, type adb reboot download
its called google search
same issue
I have been reading through xda and other sites as well and it seems like the replacement vibrants cannot get into download or recovery mode manually. I'm stuck on the phone+!+PC symbol on my phone. It's been a day now and I cannot for the life of me get this thing in download mode. Literally have tried every possible way. The funny thing is that my original vibrant could get into download mode very easily. There have been suggestions that the volume keys are disabled for getting into download mode on the replacement phones. Any ideas or suggestions besides returning the phone or waiting for another replacement?
I'm on my second Vibrant too. First one wouldn't boot into DL mode at all and I killed it when installing one of the lagfixes. Nothing worked; button combos, adb, no matter what I did I couldn't access DL mode or recovery. Fortunately I was able to get another one from T-Mobile. My suggestion would be to make sure you can boot into one of those BEFORE tinkering with anything on the phone. Chances are that if you can get back to recovery you'll be ok. If you can't get there on a stock phone then take it back to the store and tell them you're having random reboots or shutdowns. The store rep will most likely try to do a master reset. If it won't boot into recovery for them they should give you a new one. Good luck!

F'd up my vibrant i could use some help!!

hi guys... so i don't know how i got this vibrant soooooo far gone .. im afraid i have gotten it too far...

there was a thread about that issue, turn off your phone, unplug the usb cord, plug the usb cord. hold vol up and vol down and the power button. it will come on but when it goes off release the power button and keep holding down the vol up and vol down. should go into auto download mode. then u can reload it via odin.

this is normal just continue to download mode as normal.

you can save your device through odin, plug your phone in to your computer and try to go into download mode may take a couple tries, and flash the stock ROM you can find on these forums
i have already tried the sequence to get it into download mode... it doesnt work... tried adb and nothing registers....
anymore ideas? looks like im going to have to do a warranty exchange.
The only way I can reliably get to download mode is: power off, remove battery, replace battery, hold both vol buttons, plug in usb. works every time though.

are you using a .pit file? and if so is it the right 512 .pit file?
if both those are yes, delete the one on your system and re-download it.
I had this same exact problem a few weeks back Odin would hang on the pit file, just redownloaded and it worked like a charm.
and just a quick reminder of everything out for the Vibrant right now
Only stock firmware use the 'PDA' option a pit file, and re-partition
froyo firmware use the 'PDA' option and a pit file, no re-partition
JACs kernels use the 'CSC' option and no pit file, no-repartition
i have a Bell Vibrant and all the methods don't work. i tried the 3 button (remove batt,place in batt, plug USB, wait for the the ''star" to appear, hold VOL+/- and POWER and wait for the screen to turn off, release POWER, but it just goes back to recharging screen. tried it 40 times
tried the power off, remove battery, replace battery, hold both vol buttons, plug in usb. no go as well.
ANything else? I'm stuck at the boot screen (the 'S' glowing part).
This is what always works for me.
Unplug your USB from your phone
Makes sure ODIN is ready to go on your PC
Hold down the Down Volume and Power until the download screen comes on
Then plug your USB back into the phone
fire up odin
pull your battery
connect phone to pc WITH THE BATTERY OUT
hold volume up+down and power
put battery in while still holding those buttons
the screen will light up with....something. Wait for the screen to blink and then release the buttons.
You are now in download mode!
i will try those methods. Thanks.
crap, still no. just keeps showing the battery charging. i remember rescuing my htc magic so many times, but no go on this guy.....
Odin all fired up when doing this......

Did you make sure that the USB was unplugged when you used my method of holding down the volume down button and power button together until the download screen came up?
If you are familiar with ADB. You can also power your phone on and then plug in the USB and then type in the command line:
adb reboot download
to get it to reboot into download mode.
You can also use this command from the recovery console if you are able to get to it.

Dude, the Vibrant is new to us all. None like it. So dev wise its harder to explain and understand when we are used to coming from a one press method, now were using Odin, and Thor's hammer to flash our phones, which is god awful, no pun intended.
Dont flame your fellow Vibrant user cause he doesent understand the 613 steps it involves, and every other way to do so. Help the kid.
I am also in this position, just using a finger in the socket method, if its on it'l shock me, know what i mean. Just try it all. I have a feeling its getting harder and harder to brick phones because the manufacture is not retarded, they fix them right back, and ship them back out to customers who need replacements. I know this as a friend works at an AT&T shipping warehouse.
So cant we all just hit a bong, or get a long? And help?
If someone could explain all this 512PIT, PDA, and CSC, and Phone. It would help so much, sometimes a picture is worth a thousand words. Just sayin.

Yeah man, i'll try it again!! And when do I start typing (sending out the adb command) when the power turns on? Thanks.
Question is: when i press power+vol Down, the boot splashscreen comes on (Galaxy S etc etc).....
I am sorry you have a Bell Vibrant, it is a little different than my phone. I found this hope this helps
HOWTO GET INTO DOWNLOAD-MODE:
- Turn off your Phone
- Hold VOLUME DOWN + HOME Buttons
- While holding VOLUME DOWN + HOME Buttons press POWER Button until you reach Download-Mode
- Release all Buttons
I also read that some of the Bell Vibrants had their Download/Recovery mode disabled.
http://forum.xda-developers.com/showthread.php?t=754673&highlight=bell
As far as the adb command I would start as soon as it powers on. It will say "error:device not found" at first, but just keep on hitting arrow up and hitting the enter in the command window until it accepts the command.
Good Luck

HELP: Cannot get back into Download Mode...Truly Bricked??

I'm pretty sure I just bricked my **@#*& phone trying to Flash the Semaphore 1.6.0Bm kernel
It failed the first time around when I tried to flash it via Odin.
So I took the battery out like I usually do then went to put it back into download mode... To my surprise I cannot get into download or recovery mode anymore.
I've tried all button methods and none worked. I can't get past the screen that has the cell --- computer screen.. Looks like I may need a jig now...?
Any other ideas that I might be able to try?
Thanks.
What happens when you three finger boot and just keep holding it? Same screen you have now?

You mean holding the Vol up & down, Home and power button?
Same thing.
I've left the battery out for over 20 minutes, tried it while plugged into the computer, the adapter and not plugged in at all.. Still nothing.
This sucks..
if the phone doesn't do anything at all you can probably take it in to your service center and tell them it wont turn on but it didn't get wet or anything... ubless they have some magical way to get it into download then they'll replace it if you're under warranty.

Load up Ubuntu or something and load up heimdall command line. There should be an option to kick it out of the connect to PC screen.

Thanks for your responses.
I tried the OneClick.jar heimdall method but it seems to not recognize that the phone is even plugged in.
I did just purchase a USB jig off ebay, I'm guessing that this is my last option before having to bring it back to Telus for a replacement
have you heard of One-Click UnBrick?
I have seen that screen a few times. This worked for me every time to get it back into recovery...

I got this same problem when I installed CM7 on my T959d for the first time and Odin hung after clicking [Start]. Rebooted my phone and was greeted with a nice soft-brick screen. What a scare that was.
Here's what I did:
1. Take out the battery from the phone.
2. Plug the phone via USB to the PC (odin was open)
3. Hold down [VOL -] key
4. Hold down [POWER] key
I don't remember if the SGH-GTI9000 screen popped up, but if it does, wait for it to switch back to a black screen and then release just the [POWER] key, keeping [VOL -] pressed.
That put me back in Download Mode. Fired up ODIN again and the flash was successful this time around.
edit: Also, the Semaphore kernel i see in i9000 is for JVS roms. I'm not sure how that would affect darkys, since it's a JVR rom.

boot loops at recovery???

So I have done some searching but nothing I've tried help or not the same issue.
I was trying to root everything seemed to go fine. Phone reboots and now all it does is goes to a screen with blue letter at the top left that says recovery and then reboots. I've tried to power button home button volume key combo same thing happens. Phone keeps looping, so I pull the battery. As soon as I put it back in it starts looping again, even without me trying to turn it on.
Am I screwed? I have tried adb but it cant find the device, I assume because it keeps rebooting. Does Samsung have something like the HTC RUU or would that not matter because of the boot loop?
Any help would be great!
Thanks

If you cannot get into download or recovery mode by using the
Home+VolumeDown+PowerButton or Home+VolumeUP+PowerButton
then you will need to purchase a "USB JIG" from an online store or from
eBay, it's very inexpensive $5.00 or less shipped.
You plug it into the USB port of the phone after the phone is fully
powered down. After doing that it takes less than 3 seconds for
the phone to go into "download mode" automatically.
Once its in download mode and you unplug the jig you can Odin
flash the official stock firmware/rom and have a fresh start.
I have been using a JIG for years on many models of Samsung Android
phones and it works GREAT! It even worked perfectly on a friends HTC.
Good luck!

[Q] Note 3 will not turn on

I just got my hands on a rooted 4.4.2 note 3 with safestrap already installed. I wanted to get Eclipse on it and get it going. I backed up the stock rom, wiped it, the installed Eclipse. Then, set it to Download mode, opened Odin, and flashed the unified firmware. Now, the phone will not even turn on. I have tried multiple batteries, left it plugged in for a few hours, and tried to get something to show up with Vol up + power + home button to no avail. Anyone with suggestions?

Sounds like a hardware issue to me. Have you tried removing battery and plug from the outlet and pressing and holding the power button down for about 10-15 seconds to reset it? Other than that, unless all the batteries you used are defective at the same time, I would say the phone is defective.

When you flashed the Unified Firmware in Odin, hopefully you used the AP slot and didn't use another slot.... if you didn't use the AP slot, then I'd be worried that something could have gotten messed up with the bootloader.
So it sounds like you've tried holding the volume down+home+power buttons all together, but it doesn't work any more to boot the phone into download mode....
You should check out the unbrick thread from hsbadr here: ( http://forum.xda-developers.com/showthread.php?p=54534374 ). It might help to get the phone back into download mode.
You could also try a usb jig to see if it would force the phone into download mode. Here's a listing for a usb jig on eBay that is less than $5 and the seller seems to have good feedback. The listing says it should work on a Note 3. There are also several guides on YouTube and xda on how to make one if you'd rather do that.
As long as there are no hardware problems and the bootloader didn't get totally messed up.... then if you can get the phone into Download (Odin) mode, you should be able to restore it back to stock 4.4.2 by following the steps in Droidstyle's restore guide here: http://forum.xda-developers.com/showthread.php?p=46461911
