[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

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

superman rom for galaxy s7 edge

hello
i'm new here at the forum.
i have a problem with the superman rom
i rooted my phone i installed the rom but now my phone is already 30 minutes on a red screen ( from the superman rom i think )
i cant go anymore to the recovery by using volume up home and power buttom.
what can i do? help please i need my phone :crying:

able to reboot the phone by keep pressing the power button?
if can.. 1st times reboot immediately pressing volume up, home and power button and it will reboot again.. A 2nd times reboot release the power button only.

Red screen = wrong kernel flashed (you flashed s7 flat kernel on s7 edge)(There's an option to select kernel during installation. You probably selected wrong option or didn't check it)
This can be solved easily by flashing the right kernel.
Everything but display should still work normally, so you should be able to enter recovery by holding power+home+volume up when the phone is off or before the s7 logo come up.
If you still cannot enter recovery mode. You can enter download mode by holding power+home+volume down and flash stock firmware with it and start over. But for this problem, you probably not need to do this.

Hey mate,
like NonXtreme said, it looks like you installed the wrong kernel, so just reboot your device by pressing Power + Home + Vol Down, and when the device shut down press directly Power + Home + Vol Up, now you should get into the recovery.
Now you have to reinstall the Rom with the correct Kernel! (g935f maybe).
Let me know if there are further questions.

S7 Edge stuck on boot logo ( G935FD )

I tried flashing the bootloader from here.
Then it went crazy or something, and got stuck on the powered by android logo, however i was still able to boot into download mode the first time by holding power + volume down button
to simulate a battery pull then quickly holding the volume down + home + power again. Then I tried flashing TWRP immediately in an attempt to make it work because i have a flash drive to microUSB adapter that allows me to read flash drives from my phone ( so that I can flash the rom properly ). The last time I was in TWRP there was 0 things in my storage everything was wiped after I flashed TWRP the first time
Now im trying to go back into download mode but it just wont let me after the battery pull.
1.) After simulating the battery pull, I immediately let go when the screen is dark.
2.) I immediately attempt to go into download. It shows the powered by android for a second, then flickers then it's back to the powered by android again.
3.) I think my recovery and download is screwed. Or something is going on
=== EDIT ===
I managed to get into download mode and flash back my stock rom.
I think the phone must have read my Power & Volume Down & Home button as the battery pull because I let go of all buttons completely before doing it.
Steps to get out of bricked hell:
• Hold Power & Volume Down until the phone turns off
• Immediately without letting go of the Power & Volume Down button, press the home button as well.
• If the timing is not correct just retry.

Soft bricked my T280 and so confused!!

I recently updated my Samsung Galaxy Tab A T280 to the latest firmware and I lost my root. So this afternoon I re-rooted it. Or I attempted to, anyway. Everything seemingly went fine, and I booted into TWRP just fine. I went to flash the ROM and I also selected wipe cache/davlik cache to be done as well, and tapped reboot. My device then turned off and when it started the reboot, it got stuck on the Samsung Galaxy Tab A logo screen and would not move or power off by holding the power button (I tried for a LONG time by using a rubber band to hold it down so I didn't have to, with no luck), and every other combination of buttons wouldn't do a thing, except for holding power + vol down, which made it turn off and back on, but it wouldn't finish rebooting and it just got stuck at the Samsung Galaxy Tab A logo again. So then I thought that maybe plugging it into a charger might not be a bad idea, and after holding down power + vol down again, it turned off and turned on and showed a battery with a charging symbol. I've had it plugged in for an hour and it does not show a charge or do anything except for go back to that boot logo if I unplug it from the charger and again hold down power and volume down separately.
I know it's not hard bricked because it is somewhat responsive so I think there's a chance to fix it, hopefully. I just want it to turn on and fully reboot into anything or in any way that will allow me to be able to fix the issue. My computer will not recognize the device so ADB is not an option right now unless I'm wrong.
Thanks a lot guys, I am so confused and could really use some advice.

What firmware did you install

Try to install original firmware via software "Samsung Smart Switch" on your PC with connected tablet.

I too recommend that you try installing the last firmware that you were on via Odin. Also, when you hit that screen lock issue after a firmware flash, where only the Samsung logo appears do this:
1. press and hold Home + volume up and volume down along with power button (that's all 4 buttons). Hold it there for at least 20 seconds and it should power off.
2. Once the device powers off keep holding the buttons but let go of the volume down button.
3. Once the tablet starts to power back up again release the power button and then in about 1 to 2 second release the rest of the buttons.
This should get you back into recovery. You should at least be able to restore any backup, that you should have already, on your external micro SD.
Good luck.. : )
"Chance Favors the Prepared"

the above post is 100% right. Reboot back into recovery and you'll be good to go. Also twrp has a option to reboot back to recovery so this doesn't happen, just a fyi for future knowledge. Best of luck..

You tried to flash a rom with twrp?
You need to flash stock firmware with odin.

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.
