Holding ( power button + volume down ) while the device is off power didn't make any thing ?
This is curious if you didn't make any modifications
Try this and post what is happening
Any info about the device is useful ( except serial and imei numbers )

Well, i check yesterday with multimeter , battery is 0Volts, and the connector before the flat of battery arrived like 0,86v...seems there is something wrong.
However if try that combination of button not work.
I found this code on the box
P/n: 99HYK076-00
nmu 767406

remove you serial number
the device boot but stuck at htc logo ? If yes try that
Boot the device until it stuck at any screen then
Hold power button + volume up for a few second until the screen goes gray then immediately sweep your finger to press and hold volume down while holding power button
This should take you to the bootloader
hope it will help

lmfao relax. Hold your volume button down, hold the end key down(the button you hang up the phone with) then push the power button.
When your phone boot you should see a gray screen that say serial, plug your device into the computer and serial should change into usb. Then run the rom and there u go

Doesn't that trigger Ramdump mode (well, I don't know what that means, actually)?
All the OP needs is to go to Bootloader Mode to flash a ROM via USB. Bootloader is easily accessed by: Turn off phone, then press/hold Volume Down + Power button.
thanks guys, ive been using android, and never a minmo device, thanks everyone!!

Sortof. I just tried task29 for the first time a few days ago. I freaked out when I got in the same situation as him, but then read through the thread. There's the option of shutting the phone off, and pressing vol down + power key. I ended up doing vol down + power key + push reset with stylus at the startup screen. Simplest solution for me.
taking off the battery, istnt that simplest?
Amd here is the theme about this

In the very first posting of the Task29 thread, it says :
When phone boots to "Touch Pro 2" screen (or whatever your splash screen happens to be), I hold down the volume down button while hitting the reset button.

IMO, the smartest thing to do is when Task29 is near 100% (I think it pauses at around 96%), hold down the Volume Down button. That way, when the phone (tries to) reboots, it goes straight to Bootloader.
thanks all you have been more than helpful, ive been using this site for a while (for my android device) but just recently made an account. All of you keep on getting it done!!!
Moved as not ROM Development.

Hey, I have a Touch Pro2 and I tried the key combination above and it didn't work for me. I did get it to work however using the send key (green button) instead of the end key....
I.e, held volume down button, held send key and pressed power key once... ;-)
Phone MUST be off before doing the key combo...

Is this phone Rooted? well try this pull the battery out put it back in, and press and hold volume down button and press power and see if you are able to get into boot loader...
tricky !
two options
1- check bootloader (volume down + power) , if it gets a white screen with options , you can repair the device.
2- if it does not go into bootloader , then first download Htc sync for desire z , setup the android SDK , then plug ur phone inn, in command prompt , type *adb devices* .
If it shows a serial number below List Of Devices , then get back to this forum and report
And the last thing is the power Hardware button fine ?? Although quite impossible , but the hardware power button might be faulty !!

Stuck in orange bootstate, no recovery mode possible!

Hi there. After (an attempt) to unlock the bootloader of my A50 and installing TWRP Recovery (TWRP_A50_Magisk_Prepatched) i find myself in an orange bootstate. I can't get it into recovery, download or fastboot mode. It seems like a full brick. I can't even power off the device. Only Volume up, Volume down and Power button let's the device reboot but then the same boot problems appear. Is there anything i can do to recover my phone?
Text of first screen when booting up:
"The phone's bootloader is unlocked and it's software integrity can't be verified. Andy data on this phone may be vulnerable to attackers. Don't store any important or sensitive information on this phone". Press power key to continue"
Text of second screen when booting up:
"The phone is not running Samsung's official software. You may have problems with features or security and you won't be able to install software updates"
Any ideas!?

Try connecting your phone to your PC with the USB Type C cable, and do VolDown + Power to reboot the phone, and the moment the screen turns black, press VolUp + VolDown. It'll bring you to a different screen where you can press VolUp to go into download mode for flashing the stock firmware via Odin. I got my stock firmware from https://samfrew.com/all/page/2/#t (you'll need to search for your Model Number - SM-A505F/SM-A505FN/SM-A505FM, and select the correct Region. Also, select the correct Modem Version (the last 4 letters/number of the item to download). Then, follow the "Flashing Guide" at the bottom of the Samfrew page where you downloaded your firmware.

How do I find out what is the correct region of the correct Modem Version of my phone? It's an S10 (intl unlocked) that I bought in the US from Amazon.

You can find answers in the S10 forum. But I think the steps will be the same (this is A8 device/forum).

My bad. Apologize. Will head over there. Thanks!
No bother. Hope you are sorted by now.
this is the exact same problem that goes for me with my samsung a505gn, i flashed a twrp 3.3.1-2_zvox and im stuck at this state. i found my stock firmware at the link provided above, but there are multiple types of a505gn stock firmware (XTC, SMA, GLB), question is, how do i know the correct type of stock firmware to reinstall to my phone, hence, having a limited information of the phone because of this problem (which is stuck at orange bootstate).

Have you got the a21s? As can't root it, as every twrp source I use soft bricks the phone, or just bootloops, or goes into error at boot up and stops half way. Was thinking trying other custom recovery. Any tips m8?

I HAD the same issue an I resolved it.
There are 2 methods to overcome this problem.
I even wrote a PDF and attached here in this post.
Below is SOME content from the PDF so it could be easy for users to find it on Google. I still strongly recommend you to refer to the PDF attached as it has pictures as well.
Samsung Galaxy M31 / Samsung M31 Screen is stuck on the following error message / error screen:
‘This phone’s bootloader is unlocked and the software integrity can’t be verified. Any data on this phone may be vulnerable to attackers. Don’t store any important or sensitive information on the phone.’
‘The phone is not running Samsung’s official software. You may have problems with features or security. And you won’t be able to install software updates.’ (error screen looks like below):
I was using correct TWRP and I was on Android 11 One UI 3.1.
Just to experiment, I flashed wrong TWRP version which was meant for Android 10 while being on Android 11. And so this problem started. Stuck on the error screen. Phone will not power off or on. Could not even enter the bootloader screen. Nothing works whatever keys I press. The same screen comes up. When the phone goes off and the phone will not accept charging that mean even you it whole night connected to charger, phone will not be charged- the same error screen.
So, the battery was not charging (my battery was at 24% just before this tragedy happened. It was late night and I thought of waking up tomorrow and plug in charger for an hour thinking if its battery is quite charged then I will follow Fix Method 2).
I woke up next morning and the phone was off (Battery drained fully). To this I was happy thinking that I can now hold Volume + and Power key and connect USB cable to enter Bootloader. When I did that phone would enter bootloader and gets switched off automatically (remember the battery was drained completely, charger too failed to charge battery and phone is not drawing enough power from USB port to stay on bootloader. On bootloader screen the phone’s display is fully on so more power usage).
Now I knew that the USB port is not proving enough power so that the phone could remain On while in bootloader when I hold Volume + and Power key and connect USB cable to enter Bootloader. I know for sure that Fix Method 2 will fix this for sure but it’s quite tiring.
So I referred to my PC manual to figure out which USB port provides maximum power. I found the right port (refer pic below):
So now I figured out 5 Volts port and plugged the original white Samsung M31 USB cable into one (refer the pic below):
If you don’t know which USB Port is 5 Volts then I recommend you to try all the ports and try getting to bootloader screen.
So when the phone was off, I pressed and hold the Volume up and Volume down key and with other hand I connected USB cable and now the phone went in bootloader and then I quickly flashed the right TWRP. Disconnected the USB cable and put the phone to charge and now it was accepting charge. Phone was back into life.
So I resolved it by Fix Method 1 below:
Fix Method 1: On my PC, I located the 5 Volts USB port and plugged the original white Samsung M31 USB cable into one (refer the pic below):
Entered Bootloader screen.
How to enter bootloader screen:
Assuming your phone is unlocked and the developers options are on and you have enabled USB debugging in Developer options and you have little knowledge of flashing firmware or TWRP via Odin.
Press and hold Volume Up and Volume down keys together with one hand and using other hand, connect USB cable to phone and release all the keys. Now phone will show bootloader screen which looks like below pic:
I quickly flashed the correct TWRP via Odin:
Flashing TWRP:
· Make sure OEM Unlock is ON in developer settings;
· Turn off the phone;
· Press the volume down + volume up button whilst the phone is connected to a pc to boot in download mode;;
· Long press vol up then confirm you want to unlock bootloader (this is needed one time only);
* Please be aware all your data will be erased including internal storage and phone will reboot!!
· Let the phone boot normally, pass the setup and connect to internet (wireless or mobile data) in order to unlock RMM;
· Make sure OEM Unlock is ON in developer settings;
· Turn off the phone;
· Use Vol up + Power + usb cable plugged to a pc to start the phone in download mode, short press vol up to confirm you want to go to download mode;
* If by any chance you see RMM state=Prenormal or KG state=Prenormal, factory reset data and redo from step 5!
TWRP screen was up. I tapped on Reboot and it did not reboot because the battery was not enough charged however I saw that TWRP Menu this means TWRP was working so the phone will boot up once it is charged.
Now I plugged in charger and was happy to see the correct charging screen (refer below pic):
I would turn power switch Off and On it quicky to know the charging percentage.
When it reached 20% I started phone (obviously by long pressing power key and it booted up just fine).
I loved myself
Fix Method 2:
Remove the phone’s back cover.
Be careful while removing the back case as you could screw the finger print sensor.
Disconnect the battery connector from motherboard and reconnect it.
Do not turn on the phone. As turning On will again get you back to the same error screen.
Put the back cover on.
Connect charger. Do not turn phone On yet. Wait for 5 min.
Do not even touch the phone.
Now you need to know the percentage of charge so do not hit the power button yet instead locate the main switch to which your charger is connected. Quickly turn Off and On and look at phone it shows charging percentage.
Once charging percentage reached around 20% you can touch your phone and power it on and it should boot up fine. It should not take more than 5 min to boot up.

Connect charger. Do not turn phone On yet. Wait for 5 min.
Do not even touch the phone.
Now you need to know the percentage of charge so do not hit the power button yet instead locate the main switch to which your charger is connected. Quickly turn Off and On and look at phone it shows charging percentage.
Once charging percentage reached around 20% you can touch your phone and power it on and it should boot up fine. It should not take more than 5 min to boot up.

I HAD the same issue an I resolved it.
There are 2 methods to overcome this problem.
I even wrote a PDF and attached here in this post.
Below is SOME content from the PDF so it could be easy for users to find it on Google. I still strongly recommend you to refer to the PDF attached as it has pictures as well.
Samsung Galaxy M31 / Samsung M31 Screen is stuck on the following error message / error screen:
‘This phone’s bootloader is unlocked and the software integrity can’t be verified. Any data on this phone may be vulnerable to attackers. Don’t store any important or sensitive information on the phone.’
‘The phone is not running Samsung’s official software. You may have problems with features or security. And you won’t be able to install software updates.’ (error screen looks like below):
I was using correct TWRP and I was on Android 11 One UI 3.1.
Just to experiment, I flashed wrong TWRP version which was meant for Android 10 while being on Android 11. And so this problem started. Stuck on the error screen. Phone will not power off or on. Could not even enter the bootloader screen. Nothing works whatever keys I press. The same screen comes up. When the phone goes off and the phone will not accept charging that mean even you it whole night connected to charger, phone will not be charged- the same error screen.
So, the battery was not charging (my battery was at 24% just before this tragedy happened. It was late night and I thought of waking up tomorrow and plug in charger for an hour thinking if its battery is quite charged then I will follow Fix Method 2).
I woke up next morning and the phone was off (Battery drained fully). To this I was happy thinking that I can now hold Volume + and Power key and connect USB cable to enter Bootloader. When I did that phone would enter bootloader and gets switched off automatically (remember the battery was drained completely, charger too failed to charge battery and phone is not drawing enough power from USB port to stay on bootloader. On bootloader screen the phone’s display is fully on so more power usage).
Now I knew that the USB port is not proving enough power so that the phone could remain On while in bootloader when I hold Volume + and Power key and connect USB cable to enter Bootloader. I know for sure that Fix Method 2 will fix this for sure but it’s quite tiring.
So I referred to my PC manual to figure out which USB port provides maximum power. I found the right port (refer pic below):
So now I figured out 5 Volts port and plugged the original white Samsung M31 USB cable into one (refer the pic below):
If you don’t know which USB Port is 5 Volts then I recommend you to try all the ports and try getting to bootloader screen.
So when the phone was off, I pressed and hold the Volume up and Volume down key and with other hand I connected USB cable and now the phone went in bootloader and then I quickly flashed the right TWRP. Disconnected the USB cable and put the phone to charge and now it was accepting charge. Phone was back into life.
So I resolved it by Fix Method 1 below:
Fix Method 1: On my PC, I located the 5 Volts USB port and plugged the original white Samsung M31 USB cable into one (refer the pic below):
Entered Bootloader screen.
How to enter bootloader screen:
Assuming your phone is unlocked and the developers options are on and you have enabled USB debugging in Developer options and you have little knowledge of flashing firmware or TWRP via Odin.
Press and hold Volume Up and Volume down keys together with one hand and using other hand, connect USB cable to phone and release all the keys. Now phone will show bootloader screen which looks like below pic:
I quickly flashed the correct TWRP via Odin:
Flashing TWRP:
· Make sure OEM Unlock is ON in developer settings;
· Turn off the phone;
· Press the volume down + volume up button whilst the phone is connected to a pc to boot in download mode;;
· Long press vol up then confirm you want to unlock bootloader (this is needed one time only);
* Please be aware all your data will be erased including internal storage and phone will reboot!!
· Let the phone boot normally, pass the setup and connect to internet (wireless or mobile data) in order to unlock RMM;
· Make sure OEM Unlock is ON in developer settings;
· Turn off the phone;
· Use Vol up + Power + usb cable plugged to a pc to start the phone in download mode, short press vol up to confirm you want to go to download mode;
* If by any chance you see RMM state=Prenormal or KG state=Prenormal, factory reset data and redo from step 5!
TWRP screen was up. I tapped on Reboot and it did not reboot because the battery was not enough charged however I saw that TWRP Menu this means TWRP was working so the phone will boot up once it is charged.
Now I plugged in charger and was happy to see the correct charging screen (refer below pic):
I would turn power switch Off and On it quicky to know the charging percentage.
When it reached 20% I started phone (obviously by long pressing power key and it booted up just fine).
I loved myself
Fix Method 2:
Remove the phone’s back cover.
Be careful while removing the back case as you could screw the finger print sensor.
Disconnect the battery connector from motherboard and reconnect it.
Do not turn on the phone. As turning On will again get you back to the same error screen.
Put the back cover on.
Connect charger. Do not turn phone On yet. Wait for 5 min.
Do not even touch the phone.
Now you need to know the percentage of charge so do not hit the power button yet instead locate the main switch to which your charger is connected. Quickly turn Off and On and look at phone it shows charging percentage.
Once charging percentage reached around 20% you can touch your phone and power it on and it should boot up fine. It should not take more than 5 min to boot up.

Hi, friend. I have the same problem. But I don't even have a bootloader. When I log in, I just get a black screen.

Unable to boot into recovery or Download mode on Note10 Plus SM-N975F Exynos

Unable to boot into recovery or Download mode on Samsung Note10 Plus SM-N975F Exynos version. I usually remove/bypass FRP (google account) on devices for customers.
I have a customer's Note10plus devices which is still on pincode lock screen trying to hard reset and remove FRP but can't enter into recovery mode. Tried to enter into download to flash with new firmware but unable to boot into download mode either. Looks like the device is remotely locked via Find my mobile which is preventing to hard reset the device, anyone knows about any new security feature ?
RECOVERY MODE:
1: Begining the process by holding the Volume Down + Power key in order to shut off the phone.
2: As soon as the phone is off, hold the Volume Up and Power button till the Samsung logo appears
3: Let go of held buttons when the SAMSUNG Galaxy logo pops up.
4: At this moment i should be seeing the Recovery mode but no its rebooting and getting error : "[PDP] backup fail: setup-wizard finish"
I'm a pro in rebooting devices into recovery and download mode usually get success in first attempt but sometime have to try 2-3 times as well as timing is the key in pressing and holding the combination of keys so surely not the timing issue on this devices.
Can't even use the ADB method as well coz the device is on lock screen, Can't enable USB debugging or see the pop-up on screen to enable it due to being on lock screen.
.\ADB DEVICES - Not reading or showing the connected Note10plus via the official USB cable.
Any help or information would be very helpful and highly appreciated Thanks.
This don't even make sense. If the customer can log in on the pc and lock the screen and such they can also log in and remove it. This whole shebang seems shady and more than likely you will find no help here. Most of us do not support bypassing of frp especially since you stated the customer obviously has access to the device in some form

Samsung recently changed the download mode entry process.
1. Power down device
2. Hold volume down/up buttons and keep them pressed
3. Connect phone to a pc using usbc cable

Plug the phone into a pc with USB -c cacble whilst the phone is on and you inside of windows, in other word you need to be logged into windows 10.
Power off the phone (keep cable plugged in and pc on at all times)
Hold Volume Up + Power Button until you get into recovery mode.
plug in the official earphone the original one from the box, then try to enter to the recovery mode

Thanks man... It worked
After the second android 11 update, "recovery mode" can be accessed as follows: turn off the phone, wait 10 sec. , connect it to the laptop with the USB-C cable. After the battery percentage appears, press BIXBY + VOLUME UP + POWER BUTTON. When the logo appears, release VOLUME UP and POWER BUTTON and press VOLUME DOWN without releasing the BIXBY button.

Can someone here plese help me. Easter Sunday I get a text gif from my Sister and now I cant do anything with my S9. I read here about plugging S9 into windows machine but that scares me. I'm ready to call it quits with Samsung. This is the second device in a few years that has locked up on me. Could this be a hack or maleware? The new login feature for widows that includes a pin didnt work today either. I can get into windows fine with password. I did go to Google find my device and a map shows Africas west coast. HELP

Any solution in this problem.......?
Hi, I have a similar problem. My Note 10+ stuck at bootloader page and will not power down. I could not use normal procedures to go to download or recovery mode. I drained off my Note's battery but once I plug the charger back to charge its battery. The bootloader page shows up. Any suggestions that can resolve this problem? I attached a screenshot here. Thanks in advance.

Hey there,
I've got some possibly important questions:
Does the Samsung logo show up on boot?
How did you try to boot into download- or recovery-mode, specifically did you press the power- and volume buttons to boot, just pressed the volume buttons, with/without plugged-in USB cable?
Does ADB/Fastboot/Odin/Heimdall/Smart Switch or anything recognize your device?
Any idea of what had been flashed onto the phone?
Does the battery percentage thingy show up when you plug a charger into the phone?
Have a nice morning/afternoon/evening.
Cheers

Does it boot if you press the power button from that screen.
I believe that screen appears after bootloader has been unlocked....which probably means device is rooted.
You should be able to boot into the system by tapping the power button from that screen.

Hi,
I have tried every methods that I could think of. I left it drain the battery three days ago and once I plugged in my phone charger and immediately it show this screen. The only way i can do is press vol dwn + power, it rebooted and came back to this screen again. No metter how many times I "reboot" it still come back this.
The last flash i did was used the odin to flashed the Magisk in "AP" cause I lost my root for some reason. I followed Magisk instruction to create a patching tar from the phone itself. Then re-flashed with odin. My Rom was using "N975FXXU6FUCD". After odin prompted "pass" and I left it to reboot. It usually will show this screen a while after rebooted.( normally it'll take around 45 sec to full boot but not this time.) No boot to Android page after left it about 10 minutes thought it still initialize.
I left it almost half an hour and phone still show the bootloader page. What i did was try to reboot or power off by press power button. I couldn't power off it even i hold the button for about 15 sec. Next move I just tried press vol up + power , vol down + power, insert USB plug while holding the vol up + dwn + power. I tried the combination of buttons and last I left it to drain out power.
I'll try if any other suggestions. I don't think there's a reset button unless open out its case..

Hey there,
With my N10, the combination for getting into Odin-mode is vol-up + vol-down and having a cable plugged in to a computer. Please try "rebooting" your phone (while having it plugged into your computer) and immediately after the screen goes blank, press vol-up + vol-down (without the power button).
I would recommend first trying to flash the full stock ROM (AP, BL and everything else you get) and if it boots, try modding it again.
Have a nice morning/afternoon/evening.
Cheers

Question Why wont my S22 go into Download mode or recovery mode?

So I have spent hours now looking around for an answer the phone is find my phone locked and I can't remember my pin code. I have done all the tricks with the combination keys.
The usual way to get into Recovery mode is Hold V+ and power until the phone vibrates and you should be in recovery mode release the keys. (Doesn't work)
Iv read that you should have the USB cable connected from pc/laptop while you do the same holding V+ and power button... (doesn't work ether)
and download mode should be very easy just hold V+ and V- plug USB cable from pc/laptop and you should get into download mode by pressing V+. Will only show charging Icon and that's its.
So is it possible to turn off this modes from the manufactor? Or is this a completely new security future? How can you use odin? How can you wipe the cache? If you end up having some issues.
Im going nuts....
No way to get into fastboot ether. So if anyone know why this is happening to me or got any solution I would appreciate it.
Plug in your cable with the phone turned on. Hit Power Off and wait for the phone to fully turn off. The charging logo will show up so let the animation do its thing. After maybe 20 seconds, press Volume up + Power and keep them pressed until you boot to recovery. If the command wasn't recorded in the first place and the phone is still off after more than 15 seconds, let go of the buttons and press them again and keep them pressed until it boots in Recovery

It will not work. How the hell should I be able to cle3ar cache if I got a boot loop ??? They can't just turn off recovery mode mand download mode??? This is so strange even paying for a frp reset but not even he does know what wrong??? Can they turn off fastboot, recovery mode and Download mode on this new phones? Is it because its locked with find my phone? 1 week researching now. It will only vibrate. And my PC cant find my phone anymore worked fine 30min ago nothing has changed... So annoying never seen this happened before every combination with buttons to get in any mode doesn't work only vibrates and go to pin lock screen...
Take it to a Samsung Experience center at best buy. Or send it into Samsung for repair.

thats a solid advice assuming his bootloader/recovery/download mode is fully functional then this advice works, in his case and in mine too it does not work and trying to get to the root of the problem is the key. In my case recovery mode gives error on screen so it may have to do with the way firmware is installed as these modes are not accessible.
have you sorted it out? Its nearly a year onwards =)

This, at index 2:48 minutes.
It needs to be connected to the PC. Another screwy quirk Samsung added recently. Your button timing/sequence matters as well.
On my N10+'s you can go into recovery directly with a restart if you do it right. Otherwise they will puke on you.
