SM-G970F S10e unlocking bootloader - Samsung Galaxy S10 Questions & Answers

Hi,
i have a new S10e with latest DTM stock software G970FXXS3ASJG but i have problem following the guides to unlock the bootloader. In developer options i enabled oem unlocking (it is not grayed out yet).
First the combination of bixby and vol- does not boot to download mode -> but it works with vol+ and bixby button for recovery mode and then select reboot to bootloader or over adb with adb reboot download.
when i am in download mode all guides say to long press vol+
but nothing happens -> on the screen is only written press 7sec vol+ and power to cancel download mode/restart phone
Is the bootloader unlocking broken with latest firmware or am i doing somethin wrong ?
best regards,
Thomas

You think it that easy?
Sorry, you're using Samsung.
Check the guide, backup your data, as it will get wiped:

sorry if nobody understands me but the following steps do not work on G970F with the latest firmware ASJG :
"Power off your device. Press Bixby + Volume Down and plug in your device to a PC to boot into download mode
Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot"
i have to use adb or the recovery mode to get into download mode -> bixby and vol- does not work anymore
and the second in download mode there is no option displayed for long press vol+ to unlock bootloader
EDIT:
Good news ! I made it into the right download mode.
There are 2 download modes, 1 with the option to unlock bootloader and the second one without (can be reached with adb reboot download described in the guide is the wrong mode)
I had problems when trying the key-combo i pressed vol- and bixby (with connection to pc) for over 10 sec but it don't wanted to go to download mode.
For me it is now easier to get into real download mode for bootloader unlocking -> hold vol- and bixby and press power (ca. 1 second only)

Bootloader mode: To access this mode, turn off the SGS, and then press VOL UP + HOME pressed while pressing Power. Then you will enter recovery mode.
In recovery mode you can wipe the system and you can flash a file named update.zip (if you have installed a such file in the root directory of the internal memory). These update.zip files are usually made to root or modify the SGS, and if you want to install a custom ROM, it might be necessary.
If you have installed another recovery image, the bootloader/recovery menu might have some extra features, i.e. nandroid backup and access to other settings.
Download mode: To access this mode, turn off the SGS, take out SIM and SD card, then press VOL DOWN + HOME pressed while pressing Power. Then you will enter recovery mode. Then the phone will say "downloading", and then you should connect the USB cable to a PC running the Odin firmware tool. Read more about Odin and firmwares on samfirmware DOT com
Disclaimer: Not every SGS has this 3-buttom combo - if not, search forum for "3-buttom combo fix"
Hope this helps you.

Hi Sparkle1975, I've searched the forums and read many times what you have copied and pasted.
In your answer you say that Bootloader mode is Recovery Mode.
(Bootloader mode: To access this mode, turn off the SGS, and then press VOL UP + HOME pressed while pressing Power. Then you will enter recovery mode.)
Within the app Quickboot it offers the options of reboot, recovery, bootloader and power off. Recovery and Bootloader appear to be different options.

Just in case anyone else has the same problem as me:
For me VOL UP works, so I can get in to update mode, but VOL DOWN (download mode) does not work. If I enter update mode, then hold power until it reboots, quickly presses VOL DOWN+HOME (but not power) it enters download mode.
A few more steps, but it works.
Official swedish 2.3.3 firmware in mine.
Edit: This was tested a few times with the SIM and SD out. I haven't tried it with them in.

Nokia 8 unable to boot into recovery

Hi
I need help to reboot into recovery.
Have tried most methods on youtube and most android webpages.
The vol up or down and power key all combos.
Only thing i could get was into safe mode.
Model: TA - 1004
Hardware: 64gb storage/ 4gb ram
Software: Oreo8 and was nougat 7.1.1 (didnt work for both)
Dev options: OEM unlocking selected.
Appreciate if anyone can help. Thanks!
Hello,
1- Nokia off.
2- Plug USB cable (mandatory).
3- Then push on vol+ until android robot appears.
4- Then push Power On first, maintain it and then press Vol+ to launch recovery menu.
Works fine for me.
Regards
Christian

Appreciated ty. gonna try
This does not work for me. I've watched videos on YouTube, and still, nothing. If I hold down the volume-up and power buttons, I just get the android logo over and over. This is a pretty essential functionality to be lacking. Someone on Nokia Support forums said some of the phones do not have a recovery?
Personally I tried several methods for booting into recovery, using the button combinations that were instructed on different sites. In the end the only method that worked for me, was enabling Android debugging and using adb to boot into recovery. Too bad that after all that, the recovery was of no help for me, as there was no option to wipe ART cache.

Same experience here, and again I was going for a cache wipe, but apparently Oreo manages cache different to Nougat. Here for what is worth, to the original questioner, is the note I made having finally got into recovery after many frustrating attempts:
1. Connect via USB cable to PC
2. Ensure ADB debugging is on and the "Transfer Files" mode is selected
3. At the command-line type: adb reboot recovery
The phone will reboot to an image of an android robot on it's back with a red exclamation mark and "no command" written on the screen
4. When you see this, first hold the power button down and then, while still holding the power button, press Vol+
You should now be in the recovery menu

I played around with this method, originally Posted by cb_diamond, and found it sometimes worked and sometimes didn't, this may be of help to the first questioner. Almost the same sequence as previously described but holding down Vol+ before attaching the cable, this seems to work consistently for me.
1. Power off your Nokia 8
2. Hold Vol+ down (and continue to hold it down)
3. Plug in a USB cable from your PC into the phone, after a few seconds "Powered by Android Appears" and several seconds later the image of the green android robot appears on screen. You can now let go Vol+
4. Next hold the power button down and while doing so press Vol+
Hopefully you are now in the recovery menu

How to run TWRP on P10 VTR-L09?

As a newbie hoping to root my P10, I have just entered a magical world that is confusing to me. After reading many posts about installing TWRP on the P10, I have no success running TWRP: all I get is the stock EMUI recovery.
Am I missing a secret maneuver?
This is what I did:
1. Unlocked
2. Powered Off and On
adb reboot bootloader
fastboot flash recovery twrp-3.1.1-0-vtr.img
3. Power Off
4. Try to Power On with Power + either Vol Up or Vol Down for a few seconds
Each time, I get EMUI Recovery instead of TWRP.
Would love some insights on that. Huge thanks in advance for any gentle guidance you can give.
Try to unplug the usb before you boot into recovery.
This should work.
To get root use the magisk tutorial. It's the safest method and you can hide it from apps.
Thank you for your advice, @Hamburg.
Oddly, the device still boots to EMUI Recovery instead of TWRP.
Same when I use
fastboot flash recovery twrp_3.1.1_fromfuture.img
First there is a screen that says that the device is unsafe because it has been unlocked, and to press the Up Volume for three seconds to enter recovery. That's when it boots into EMUI Recovery.
Shortcut combination is tricky to enter recovery, it usually require several attempts to get it right. With these devices, after logo, it is vol down + power again if I do not remember wrong (not just volume). Check the button combination again, just I case
Don't press the volume down button when the bootloader screen tells it.
Start the phone with this instructions:
Press and hold the power button until the phone vibrates, press and hold volume down and release the power button.
Hold the volume button until twrp shows up.
The Bootloader screen will also be present but will show you something linke "booting recovery" instantly.
If you get to the UI you can also boot into TWRP with the ADB and Fastboot Tools "adb reboot recovery".
I flashed TWRP 3.1.0 and it worked fine.
Maybe you can also start the recovery image from Fastboot directly by "fastboot boot recovery [VariableNameofTWRP].IMG"
Thank You!!!
Thank you so much @Jannomag and @ChipCollector !
Both of your instructions work (on my phone with Volume Up instead of Down).
In case someone else is reading, here are the full details to load TWRP on this particular phone.
1. Unlock
- get unlock code from https://www.emui.com/en/plugin/unlock/detail
- adb reboot bootloader
- fastboot oem unlock UNLOCK_CODE_FROM_THIS_URL
2. Install TWRP
- Remove cable, reboot, plug in
- adb reboot bootloader
- fastboot flash recovery twrp-3.1.1-0-vtr.img
( substitute your image name, e.g. twrp_3.1.1_fromfuture.img )
3. Run TWRP
Unplug, power off, then EITHER
- Remove cable
- First Option:
--- reboot, plug in
--- adb reboot recovery
- Second Option:
--- press Power until the phone vibrates
--- immediately press Volume Up and hold, quickly release power, keep holding Volume Up until the TWRP screen appears.
Now I'm at the scary place where I have to do make the right choice and not brick this thing.
The question is answered, so I will ask my next question in a different post.
Huge thanks!!! :good:
Hi guys, who has a working link for a P10 (Emui 9) TWRP image?
Thank you in advance

Question Question about booting into Boot Loader

I'm now finally trying to flash the T-Mobile version onto my sm-g998u1, When I follow the instructions to get into bootloader it just restarts the phone normally like a regular reboot? Any guidance on getting this done correctly. Below are the steps I saw how to reboot into bootloader:
Turn off your Galaxy S21.
Connect it to your computer using a USB cable.
When the charging percentage level animation stops, hold the Volume UP + Power keys simultaneously for 5-7 seconds.
Keep both the hardware buttons pressed until you enter the Android Recovery mode.
Once you enter the recovery mode on your Galaxy S21, highlight Reboot to Bootloader using the Volume Down key and select it using the Power button.
Your Galaxy S21 will boot into the Download Mode
Much thanks and sorry again for the many posts.

Hi mate
Maybe step 3 is not quite right, you can check this thread it has a lot of information
Reboot Phone in Download Mode: Connect USB-cable to your computer. Hold down "Volume up" and "Volume down" at same time. While holding down, connect the USB-cable to your phone. Or use the command "adb reboot-bootloader"
Do not wait for the % animation.....
Further information here
You can also do it via ADB (adb reboot download)
Thank you. Appreciate it.
Glad I could help

Recovery Keypress Not Working (Android 12)

Howdy, folks. I'm having some trouble getting A12 to enter the stock bootloader mode. Seems the Pwr/Vol+/Bixby combination is no longer working. Can you point me in the right direction?
Thanks!
Hello Bill Lechat
Use low vol + bixby + USB cable plugged into a PC to boot the phone into download mode
Long press vol up then confirm you want to unlock the bootloader (this is only needed once)

Yes, I was able to do that and successfully unlock the bootloadfer, but I am not able to boot to recovery via the old method of keypress only. Is there a new sequence?
