[Q] Problem with download mode (N900) - Galaxy Note 3 Q&A, Help & Troubleshooting

Hello guys.
So I just flashed the russian Lollipop firmware that came out for the N900 into my device. I followed all the procedure to the letter (I am really cautious and it's not the first time I've flashed stuff); went to download mode, connected my Note to the cable, added the MD5 to Odin and started flashing. The procedure finished and the phone restarted, but I got a black screen after the "Samsung Galaxy Note 3" screen you get when you start the phone, but that wasn't really the problem since I read that a lot of people got that black screen and solved it by flashing the firmware again. My problem is when I go to download mode (power off the phone then volume down + power + home) I get the "Warning!!" confirmation screen, and then I press Volume up to continue, nothing happens!! Even when I press Volume down (which should get out of download mode and restart the device) nothing happens!
In case you're wondering, I can get with no problem into recovery mode.
Is there a way I can fix this and get into download mode? Maybe a way to get directly into download mode without the confirmation screen (I did read somewhere that holding volume up + volume down while turned off and then connecting the cable to the phone should get it directly into download mode, but that apparently doesn't work for me)
Help would be much appreciated, and sorry for the bad english.

[Q] Galaxy Note 4 stuck in boot loop with No Command window no acces to recovery mode

I've encountered the following problem with my Galaxy Note 4: I just bought it online from a guy who turned out to be a fraud and I was not able to find or contact him again via the internet market place. So that was really stupid of me...and expensive...and I regret it very much and with hind site I should have picked up the signs but...o well you got the picture...I got ripped.
Anyways after careful inspection it turned out to be a real genuine Note 4 N910F with 64 Gb but with a korean or chinese or something recovery mode (I saw it once when I got home), an imei not to be found on any stolen phone list and working correctly with an european rom that includes English and Dutch at that point.
That's when I decided to factory reset it and then I got into trouble again: For some reason it got stuck in a boot loop with just a No Command message. Normally you can reach the recovery mode by pressing Volume Up +Home +Power but now nothing happens. It's not a real brick but with just the No Command message and no access to the recovery mode I don't know how to fix this.
Can anyone help me with a clue on how to get out of a No Command loop without recovery mode? Or how to get into recovery mode if start with Key Up etc does not work? Or any other clue that could help me?
Thanks in advance!
Kind regards,
Rene (aka the guy who got ripped off but hopes to save the phone)
Can you get into download mode?
Thanks dr.mOx for responding!
I tried both volume up+home+power to get into recovery mode and also volume down+home+power to get into download mode but in both cases the device starts and shows me the android robot on it's back with a red warning triangle containing an exclamation mark and below the robot the message "No command." . The screen blinks every two or three seconds. The power button is not shutting the phone down in this state. I have to remove the battery to retry.
Battey out. Then in. Go to download mode. Flash stock rom with odin
Sent from my SM-N910F using XDA Premium 4 mobile app
Hi Ozzyblack. The thing is that, if I'm correct, when I press volume down+home+power to get into download mode I expect some sort of menu to appear asking to go into download mode or not. Am I correct? I saw same sceendump about that. And now I keep getting the No Command window. Do you think I miss something here? I do press volume down first, then home (keeping volume down pressed), and them the power button (keeping all buttons pressed). After a few seconds the display turns a bit more grey for a sec and then the android robot appears. But no message of sorts about getting into download mode.
Hi reborn67.
**Only if you have a galaxy note 4 N910F model**
If you can get into download mode your safe, and you can reflash an offical ROM, there is no menu system in Download mode so don't worry.
Don't stay in download mode forever or a long time, i.e. power off and wait till you have the ROM and Odin before you go into download mode as it sometimes times out even though it still shows in download mode.
Go to here http://samsung-updates.com/details/37086/Galaxy_Note_4_Snapdragon/SM-N910F/DBT/N910FXXU1ANK4.html download the ROM, and then download Odin here https://mega.co.nz/#!UdRRyCAT!H4FyVxYynNWvXqRNmnpMGQRCP-dG3uykgP2pT4rh8Ek
These are the instructions from sammobile on how to flash ROm with Odin.Instructions
1-Extract (unzip) the firmware file
2-Download Odin v3.09
3-Extract Odin zip-file
4-Open Odin v3.09 (make sure the extracted rom file "N910FXXU1ANK4_N910FOXA1ANK4_N910FXXU1ANK4_HOME.tar.md5" is in the same folder as Odin before opening up Odin.
5-Reboot phone in Download Mode (press and hold Home + Power + Volume Down buttons)
6-Connect phone and wait until you get a blue/orange sign in Odin (above text top left ID:COM)
7-Add the firmware file to AP / PDA
IMPORTANT** Make sure re-partition is NOT ticked
Click the start button, sit back and wait a few minutes
I always do a hard reset after flashing new ROM's (settings, backup and reset, factory data reset)
I have a network locked UK N910F on EE and use this German ROM with no problems, this ROM has little bloatware.
Thanks gadjet. I do have odin and a stock rom ready for use now:
1-I tested odin and the usb port plus driver setup with my 'old' galaxy s4 and within a second the ID:Com in Odin turns blue. So that seems to be working fine.
2-So now I put in the Note 4 battery and connect to usb WITHOUT ANY KEYS PRESSED...just to test! And the usb connection bleeps from windows confirm a device is connected...so far so good.
3-Last and most important step fails: Reboot phone in Download Mode (press and hold Home + Power + Volume Down buttons), the 'no command' robot is still there, and also connect phone and wait until you get a blue/orange sign in Odin (above text top left ID:COM) never happens. And also there are no windows usb connection bleeps so apparently there's a difference when I tried to select download mode.
Please know that I'm really thankful for all the great tips. But I guess I'm still missing something here.
Kind regards,
Rene

Unfortunately Kies 3 (latest update) does not recognize any connected device when I try this. The No command screen is laughing at us again
This is different
Turn your phone off or make sure it’s turned off.
Press and hold the Volume Up, Home and Power buttons simultaneously.
When the phone vibrates, release the Home and Power buttons, but keep pressing Volume Up button.

OK, corrupt boat-loader Samsung service centre repair job, or local phone repair job.
Requires boot chip to be reflashed at board level.
Sorry we couldn't get you going bud..:crying:
Thanks for trying guys!
I'll see if I can find a local phone repair store.
I used to have the same problem with my SM-P605 when I flashed some ROM in the summer, the only special thing I did was not giving up and after all I got to the Download mode. Hope it'll work for you without Service.
Good Luck
Today I went to visit an official Samsung store. They told me I bought a very good but fake Note 4 and it is not likely it can be recovered. The weight is incorrect...a bit to heavy. Also the serial numbers are unknown in the samsung database and some other details were not correct. Thanks again for trying to help me! I now officially have a really expensive brick that looks like a note 4.:crying:
same issue i am facing..i tried all..but it shows no command error and no menu shows up
ill be going to get my phone checked today..if i get any way out ill let u know
What you did later to recover ? I'm facing the same problem I've visited samsung service centre but they are unable to solve it.
Can you guys help me for my phone Samsung note 4 because its just keep repeating in a logo SAMSUNG...
I tried pressing volume down+home button+power then got "WARNING CUSTOM OS... and stuff and then I press volume high+home button+power then I got the logo SAMSUNG that keeps on repeating. Please help me what to do

I have the same problem, no download mode on my G2 (European version, stock kitkat without root, bought it a week ago).
Just to be safe, the way I tried to launch it into download mode was:
1. Powering off the device.
2. Holding the volume up button.
3. Plugging in the USB cable (while still holding the volume up button)
The LG logo shows up for a while, after which the charging animation shows ups...

Your phone must be turned off
So, press power button and select “power off”.
Then, press the volume up button on your LG G2.
While you are holding the volume up button, plug in your phone’s USB cable.
Keep pressing the Volume up button until the download mode is being displayed.
that is the known method for G2 unless you flashed a custom boot-loader or changed the keys to enter download mode or recovery etc .... now try to enter a hard reset mode but don't apply it or all your data will be gone i say again don't approve it it is power+Vol down
if it works i think the keys combination are still in default then try to enter download mode again
if it didn't work return the mobile to be fixed or changed
Thanks for your reply!
The method you described is the same as the one I used, unfortunately it doesn't seem to work. I can't seem to get it to boot into recovery either...
I believe this reddit post describes my problem:
https://www.reddit.com/r/lgg2/comments/2n4gqa/unrooted_lg_g2_on_stock_android_442_kitkat_will/
The OP's conclusion is:
So I rooted and installed AutoRec and that got me Download Mode. Afterwards I used LG Flash Tool to flash the stock KDZ file onto my device to unroot it and to see if Download Mode is still enabled which it was not.
I believe this is LG's way of preventing users from upgrading to unofficial/unreleased firmware.

I managed to fix the issue by performing an emergency recovery using LG software. It must have been caused by one of the OTA updates.

Unplug usb from the phone.
Press the power and volume up and volume down and home buttons at the same
time.
As soon as you feel vibration let go of the volume down button while pressing
the volume up, power and home button until you see the samsung logo, then
let go of all the buttons and it should boot into recovery mode.
If it does not boot to recovery mode after doing the above steps 3-4 times
you will need to press volume down and power button until the phone
goes into "download mode".
Once in download mode you will need to re-flash the stock samsung
firmware again.
But this time make sure you flash the correct official version and model#
for your phone's model.
Good luck, have a great day!

Stuck on AVB Fail

Hey guys, yesterday I tried to reset my phone and lock the boot loader because I was going to sell my phone but I got stuck on (ODIN MODE : AVB Fail ) screen. and no matter what key combinations I use the phone goes back to the same screen and wouldn't let me go into recovery or so.
I saw online that some said to flash the official ROM in ODIN and it will get back to working again but my laptop doesn't recognise my phone when I plug it in
Please help me if someone knows a fix for this.
I use a MacBook Pro M1 if anyone is wondering
I have S10 stuck at Download mode as well (though of a different reason).
For me at least putting into recovery mode works like this:
turn off the phone
(it automatically goes to download mode)
plugin the phone to the PC (this step might even be optional; but is required for me for some reason)
cancel Download Mode with keys as instructed on the screen:
Volume Down + Power (more than 7 secs)
IMMEDIATELY after try to put the phone into recovery mode:
hold Volume Up + Bixby + Power
Then from recovery you might be able to do smth

Galaxy A40 infinite loop - impossible to turn on

Hi!
I have a problem with a galaxy a40 device, I flashed a stock ROM with Odin, everything went fine, green lights, PASS and all, but now the device just won't go pass the SM logo anymore. When I turn on, logo appears 2-3 secs I get a warning of the unlocked BL then logo comes back and after a second the phone restarts itself and the same goes on forever ( well about several hours, and after that it just shuts off somehow ). I cannot enter recovery mode or download mode at all. I keep pressing the combinations Power + Vol Down, Power + Vol Up, All three and every combinations I have just found on the internet so far. Odin doesnt recognize the phone, which is not a surprise since it won't start up. I have tried with adb but waiting for device is all I get.
How is it even possible that I cannot enter download mode at all? There was no problem with the physical keys, and the power still works, I cannot test the Vol buttons tho.
Has anyone ever had a problem like this? How can I come back from this? Is there a way to flash a ROM without download mode or turned off phone?
Thanks for any help!!
The download mode for this model is different from previous Samsung's :
IIRC, with the phone off, you need to hold VolumeUp and VolumeDown, then plug in the USB cable connected to a computer (you may need to press Power to power up the phone, I can't recall properly).
From there, you should be able to restore a stock ROM with Odin.
Let us know if it helped !

Here the same problem, have a40 in loop and never get rocgnized for computer, tryed many different cables, and installed a booring large amount of drivers software and nothing...
you need to power off device completely. let battery drain if you can't shut down. press and keep holding volume down + plug in usb cable for Odin3 (I doubt both?)

Generic answers, repeated 800 times why really need to waste a post with that? and that not was the problem:
1- For no usb recognition, is this phone bad design, in the back tap where is the battery in the samsung logo more or less if you push with fingers and charge is because the design of baterry is so crap and your usb port goes off when the under tap cable moves or just get little out of conection. If you can get working after push, usb on phone will do too.
