Download mode problem - Samsung Galaxy S10 5G Questions & Answers

Hi, I'm having problems with my S10 5G, I don't know how it happened, but installing TWRP, in one of the reboots it entered download mode, I followed them as if to unlock it for the first time, but what it has done is block it , now it starts constantly in download mode, but I can't flash anything from odin because the download mode is locked, and I don't know if there is any way to unlock it in this state, thank you very much.

[Q] Note bricked - Not starting

Hey,
Well, I have bricked my Note like many others. The only weird thing is that the Note is not even starting anymore. At first there was no problem, I could boot the device. After a reboot (hour after flashing rom) the device didn't go past the boot screen anymore. It could also not load recovery. It could get into download mode, but I was not able to flash a kernel to read out the device in CMD.
After that however, the device didn't boot anymore and it only displayed the batery when it was loading. However, after some hours, even the batery didn't appear while loading. So, is this some kind of ultra brick? It didn't do anything anymore
Try connecting to odin in blind mode. Ie do same as you would nornally do to go to download mode and see if odin can connect.
Also tried that, but it did not work
My condoleances on your brick.

2) tried to install lineage OS rom for 811 but the recovery gave me problem that device is 815. Please install 815 rom, so I flashed 815 and it flashed fine and device booted and worked fine.
3)Now the problem starts, it crashed after some time and stuck in boot loop.
4)I had tried to boot in recovery and tried to restore back up image, but it crashed in the middle and after that I was not able to start to recovery.
5) Then I used the LG UP and flash kdz file H811V20r_00_0111.kdz for stock rom.
6) It flashed successfully, but device never got boot up and now I am unable to go to download mode.
7) Displaying small download mode symbol but device is stuck on the symbol and not going to Download mode.

Now my phone starts into download mode, and I flashed the original kdz h81120v_00_0425 using download mode, after flashing first time, it went to opitmizing Apps screen but restated in middle.
After that I tried multiple times sing hard reset, but it always freeze on 2nd screen when I press yes to reset.
I flashed kdz multiple time using LG up, but it stuck on LG logo with unlocked boot loader msg. not going to the bootloop.
Current condition is now I am unable to enter download mode it respond but freeze before entering download.
I can not hard reset as it always freezes on 2nd hard reset screen and not formatting.

I know I have done few things wrong in confusion, but realized later on. It is H811 TMO model for sure.
I did select refurbished while using LG UP
My phone is not completely dead.
Pressing power button it stuck on LG logo with unlocked boot loader msg. not going to the bootloop.
I am unable to enter download mode, it responds but freeze before entering download showing 4 blue dots.
I am able to enter recovery but I can not hard reset as it always freezes on 2nd hard reset screen and not formatting.
No charging, Device Manager shows nothing.
Is there a way to recover??

I'm in the same situation.
I tryed to install h81120v kdz and did it perfectly, but when the phone restarted... bootloop!
And now, if I try to enter in Download Mode, a message 'Download Mode' appear with 5 blue dots and nothing else.
My computer don't recognize it
I tryed the Unbrick method with SD Card but still the same

stuck on boot loop after flashing with Odin, please help I'm freaking out here

[SOLVED: Just downloaded latest version of Odin from Sammobile. What a relief!]
Hey guys, this is my first post so please forgive me for any mistakes.
My Note, unlocked SM-960U1, was stuck on June 1 security patch so I decided to flash to this month's firmware:
N960U1UEU2CSH2 for XAR
This got me stuck in a boot loop, which is now causing me to panic. I tried going to download mode and flashing it again but then another issued appeared:
it got stuck on a blue screen with the android and "erasing" I used HOME_CSC This isn't even supposed to erase anything!!!
I tried going on recovery mode but It didn't show up. I went to download mode then, and chose restart. That led me to the recovery mode and I chose restart again, and it showed me this:
#Reboot Recovery Cause is [[odin]RebootRecoveryAfterOdinDL]#
Support SINGLE-SKU
Block-Based OTA
Supported API: 3
# MANUAL MODE v1.0.0#
Rebooting...
That just froze and never rebooted! NO other commands work now. I am freaking out. The phone is hot also. Please someone help out!
Update
I can go on download mode now, but if I choose reset it sends me to the boot screen and then I see a dead android for a split second, then I'm in recovery mode. I can do nothing useful in there and restarting just freezes again

you might have your terminology backwards. There isnt a button in download mode to reset the phone, there is one in recovery tho.
Anyways, if you can get to download mode, youre likely gonna be just fine. Just download a fresh copy of your firmware and flash it with Odin with your phone in download mode
Battery Drained

I know it's been a year, but I recently experienced the issue. So this is for...someone else? lol
If you had a PASS on Odin and yet you stuck on boot loop, chances are your battery is drained, and it might not successfully boot to run configuration and deletion. Connect it to a power source, it might prompt it to the boot loop but do it regardless. After like 15-30 mins, you should see the battery charging indicator. You should be good!

Device suddenly in bootloop [merlin]

Hello everyone, my phone (Redmi Note 9 merlin) has started bootlooping. It can boot to fastboot, but is unable to boot to recovery (either through fastboot reboot recovery or Vol + during boot). I have tried using SP Flash Tool using the hard brick tutorial and it still bootloops even though all steps proceed normally. I have tried to flash both old and new versions of MIUI, and all of them stlil do not work.
My bootloader is still locked so I am unable to use fastboot or other tools (like MiFlashBoot) on it.
Trying to unlock it from Mi Unlock gives me an error (1004). It seems to be due to the SIM card not being the same but I have not touched the SIM card since I got the phone.
In the past I have used MiPhoneAssistant to restore it as I could access recovery mode, but now even recovery mode is out of my reach.
What should I do now?
Thanks for your time.
Do you know what could cause the boot looping? The most common one is after installing a new version of MIUI.
I'm not sure how it happened, but if it is caused by a MIUI update, how would I go about fixing it?
If it has a locked bootloader and it's still in a warranty. Visit the store where you bought it from and claim the phone has stopped working and started bootlooping.

Need help ROG 2 bricked?

Hi guys, i need help with my ROG Phone II CN ver
the other day, i was downloading stuff from PlayStore, just regular app, and suddenly it shuts off.
Then i turn in on again and it stuck on the ROG logo forever.
I force shutdown and try again, still stuck.
Then i boot into fastboot, and try to access the recovery mode, no avail, when i choose recovery mode, its also stuck in ROG logo
Now, i already try flashing raw both CN and WW and doesnt work, the result is FAILED. I've downloaded bunch of raw firmware and seems like AFT can't flash my phone.
Next i try the EDL method using the XiaomiFlash, it works and give a green success sign, BUT when i turn on the phone, STILL STUCK ON LOGO
I've try using another PC and still cant get it work.
Now i dont know what to to anymore. Can anyone help before i finally have to get this to the service center.
Is the NAND (UFS) broken? or anything else i can do?
FYI the phone still "works" like charging and even detecting normal/quick charge.
THanks guys
