Stuck on O2 boot screen

While upgrading my XDAII to the new O2 rom, I got a connection error which tiole me to disconnect the xda and do a soft reset.
I did this and it's now stuck on the O2 boot screen and wont budge, wont connect via active sync and does nothing else when I hard reset.
Have I f**ked it up ??
Please help,
Tommy

Don't panic
Just reset the device, place it back in the cradle and re-run the upgrade. It doesn't require Activesync as the upgrade process looks after its own connection.
Make sure the cradle is connected directly into a USB port on your PC and not to a hub. Also make sure the power supply is connected to the cradle.

Thanks, but that doesnt seem to help, the program just says that their is no connection.

Do you have another PC you can use? or try using a different USB port.

tried it on both and nothing, It looks like the XDAII can't start up properly and that's why it can't establish a connection. As I said it's stuck on the O2 boot screen (the one with the bubbles on it) with the version nos at the bottom and does nowt else.
I feel sick...

OK. I misunderstood. I thought you were in the bootloader screen. So you need to see if you can put the device into bootloader mode. Press the jog button (bottom middle front of device) and power button at same time whilst pressing the reset button. This (hopefully) will put you in the bootloader - a dark screen with Serial 1.xx displayed. Then when device is put in cradle it should change to USB 1.xx. Then you can re-run the upgrade.

Whayhey
DCS you are indeed the man!
Thanks for your help.

Please Help! Stuck in the bootloader screen

Dear all,
My Universal has been stuck in the bootloader screen after upgrade with DOPOD Rom. I have searched thru the threads but have had no luck so far. Has anyone out there experienced this? Please help me out
Thank you
Ken

STUCK RELEASE!?!?!
Well.very easy for start.
ROM Upgrade Failure
It is possible, in a very small number of ROM upgrades, that the upgrade could fail. The following are workarounds to get the device working and upgraded.
Device stuck in 'Bootloader' mode
When this happens the device screen will be blank except for the words:
Serial v 1.00a
The word [Serial] should change to [USB] when the cradle is plugged into the PC, and the version number below this will vary. When you get this screen, a soft or hard reset will not make any difference.
It is still possible to run the ROM upgrade file again, without using Activesync (Activesync will not restart anyway).
• Firstly unplug the USB cradle and reboot the PC
• Plug the cradle back into the USB port (this must plug directly into the USB port and not into a USB Hub / adaptor).
• Now run the ROM upgrade file again from the PC. This should just run as per normal and correctly reflash the device.
If it is still not working,try this
• Press & hold the power button
• Press & hold the Backlight button
• Push the stylus into the soft reset hole - until you see the word [Serial] on the screen.
• You should now be able to follow the upgrade process above for a device stuck in Bootloader mode.
It work for me,goodluck

Many thanks, HENNING RAS
My device is up & running again. Thanks

[How to HTC Devices] Enter to bootloader mode, USB host mode and update mode for Zune

I read XDA and other forums and I saw that users have problem with enter to service modes on device. So I prepared a video with description of how to enter the various modes of operation. I did that on HTC Titan:
Bootloader mode
For install HSPL and customROMs and for factory reset.
1. Power off device,
2. Press and hold vol down and vol up buttons,
3. Now (when holding buttons) press and release power button.
4. Wait few moments and device enter to bootloader mode (info on the screen).
-------------------------------------------------------------------------------------------------
USB host mode
For use y-cable and downgrade SPL version.
1. Power off device,
2. Press and hold vol down and camera buttons,
3. Now (when holding buttons) press and release power button,
4. Wait few moments and device enter in USB host mode (info on the screen).
-------------------------------------------------------------------------------------------------
Update mode (for Zune)
1. Power off device,
2. Press and hold vol down button,
3. Now (when holding button) press and release power button,
4. Wait few moments and device enter to update mode (for Zune) (info on the screen).

Noob here, what do I get for going into update mode

Good question. "Update mode" auto launch automaticaly when you do official update by Zune. If your device can't run this mode, you can launch him manually - that's all (from what I know).

Thanks very informative. Can you please answer the following:
1.How do I get out of SPL mode - exit Serial mode
2. If I'm in SPL mode and I plug in USB cable, does this take me directly to USB mode?
3. Do I use vol down button to move between settings?
4. What does APPSPl mean?
5. What does Image CRC mean?
Thanks

Getting out of SPL: Reboot the phone. Pop the battery if holding power doesn't work. Make sure the phone isn't actually connected and doing anything at the time!!
USB Mode: You'll be switched to USB mode as soon as the USB connection is established. The PC will take a moment to install drivers.
Yes, use the volume rocker to move up and down.
APPSPI: I don't know.
Image CRC: Cyclic Redundancy Check of the firmware image. A basic test against corrupted transfers of firmware flashing.

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).

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.

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

It is with the legitimate owner i guess but when they are entering the pin code its coming up with the error " [PDP] back-up:fail setup-wizard [FINISH]" as per the image attached.

I have that PDP toast message also when trying to enter recovery mode etc. No pin or passwords are set on my device.

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.

same thing was happending with my s10 plus my google maps and youtbe werent working video will work to 6 seconds and stop workling maps wont show routes when searching. couldnt get into recov mode as didnt know the new procedure this helped so much than you so much man

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
