[Guide] [One UI 3] How to boot into recovery in One ui 3 & above without a pc and root access - Samsung Galaxy S21 Guides, News

Reboot Your Device Into Recovery Mode
There are multiple ways to reboot an Android device into recovery mode. But after the latest OneUI 3.0 update, Samsung does not allow booting into recovery without connecting your phone to a PC with a USB-C cable. Here's a solution to easily reboot to recovery.
The steps mentioned can be applied to boot into both the stock recovery as well as a custom recovery if you have one installed.
Reboot to recovery without root access and without connecting your phone to Laptop/Pc.​
Download & Install LADB - Local ADB shell from playstore or download it directly from here.
Open Settings > About Phone and tap on the “Build number” field 7 times. This will enable “Developer Options.”
Go to Settings > System > Developer Options and enable “USB debugging” and “Wireless debugging.”
Open the LADB app. It will show a “Pairing information” dialog.
Open the recent apps screen. Press and hold on the app’s icon and tap “Split Screen” to open LADB in split-screen multitasking view.
On the bottom half, open Settings. Go to System > Developer Options > Wireless debugging. Tap on “Pair device with pairing code.” You’ll see a “Pair with device” dialog pop-up.
Copy the 6 digit “Wi-Fi pairing code” and paste it into the “pairing code” box in LADB. Copy the 5 digit port number from the IP address (the 5 numbers after the colon) and paste it into the “Port” box in LADB.
Hit “OKAY” in LADB and you should hopefully see text that says "Hello World”
Enter "reboot recovery"
And done now your phone will automatically reboot to recovery.
Note :
You can even try out different adb commands like deblooting system apps, allow permissions to apps like macdriod, system ui turner, etc and many more other adb commons without root and without a PC. (tested on Galaxy M30s)

Power off, then hold volume up and bixby button till recovery comes up works for root, no-root, pc, or no-pc. It does not matter what version of OneUI.

I was having the exact same problem last night, following the same instructions. I still could not figure out how to sideload the OTA, so I ended up just flashing the update and starting from fresh. Wish I had the answer for you.
Here was my thread asking pretty much the same thing: http://forum.xda-developers.com/nexus-6/help/disconnects-computer-entering-bootloader-t3230705

100% Stock, yes! 1 week old.
Yes i have set up ADB
I have followed the instruction until this part (i cannot post any link sorry, not authorized by xda)
The following ADB commands are for Windows machines. If you’re using a Mac, just add “./” before each command, for example: “./adb reboot bootloader”.
Assuming you device is already connected to your computer via USB and USB Debugging is enabled, you need to re-start it in fastboot mode. Follow one of the two methods below. Option A may be preferable because it’s another confirmation that your computer recognizes your Nexus device.
A) Type “adb reboot bootloader”
B) Turn your device off, then turn it back on while holding down the relevant key combinations for your device. For many devices it’s Volume Up + Volume Down + Power. You can see what your device’s key combinations are here.
The fastboot menu will appear and you should see Start in the top right. Press Volume Up till it changes to Recovery. Press the Power button to select it.
You will see an Android with a red exclamation point icon, press and hold the Power key, then press the Volume up key to show the Recovery Menu.
You will get a new menu. Navigate to apply update from adb and select it by pressing the Power button.
In the command window — make sure you are in the directory where ADB and Fastboot reside — type: “adb sideload [the full name of the file].zip” without the brackets around the file name.
The update will install and reach 100 percent.
Reboot and enjoy the latest version of Android Marshmallow.

(red arrow) and then the cmd says the null error, i am trying this now
I had the same problem. Turned MTP on and then it worked. You're told to turn it off but don't... Its in Settings-Storage-touch the ... Menu top right corner, USB settings and turn ON MTP mode. It worked well for me. I also used the Nexus Root Toolkit - makes things much easier!

There are lots of additional steps in that guide and not always the simplest way of doing it.
First thing to do is boot into recovery.
- Turn off the phone.
- Hold volume down + power
- At the bootloader screen, use volume keys to navigate to recovery and press power to select#
- At the Red warning triangle, hold power then press volume up.
At this stage, type "adb devices" in your command prompt and see if it returns your serial number or not. If it does, you can follow the steps to use adb to flash the update.
Please note, the guide talks about USB debugging. This only works in android. Nothing you need to do needs to be done via android so this is nonsense. Also the MTP option only works in android, so setting this in settings as a fix is also nonsense.

I'll try again when i have the time, thank you all.

Could be a driver issue. You'll need to check device manager. Perhaps uninstall the existing drivers and let it auto detect.
Failing that, install the Naked driver from my adb and fastboot thread (Nexus 6 general > Sticky roll-up thread > Adb and fastboot. What is it?)
I had the same issue with you until i did the following: I used wugfresh's nexus utility. Then I downloaded the respective file from XDA and saved it in the same folder as the Wugfresh's tool. Restarted in Recovery mode and chose 'update from adb'. Connected the phone with the usb having USB debugging on from before going to recovery. Started the CMD window from Wugfresh's tool (Advanced Utilities -> Launch) and check that the phone is connected (I think "adb devices") . Then "adb sideload xxxx.zip" and waited for the process to finish.
Instruction here: androidpolice 2012/11/13/android-4-2-build-jop40c-rolling-out-to-the-nexus-7-now-manual-download-link-available/
You do not have to install the full Android utility. Just use wugfresh;s cmd screen. Good luck!

Thank you guys! But after this "happy"night, i woke up to the OTA for marshmallow arrived on my phone, so see you guys on the rooting section instead, Thank you thank you for the help

[SOLVED] Can't enter safe mode

The phone doesn't start after installing EdXposed and the Riru Core Magisk module.
I want to enter Safe mode, but it doesn't work. I somehow managed to enter safe mode previously out of pure coincidence (no idea what I did, I pressed some buttons and i got there during a boot sequence, but it was nothing like the tutorial that Google gives you on how to do it properly).
So, I read you can do it like this:
https://support.google.com/pixelphone/answer/2852139?hl=en
However, this doesn't work for me, here's my boot process:
Power on
Unlocked bootloader warning (I skip it)
Google logo shows up
Screen color calibration changes slightly
Google animation starts (i press volume down)
Google animation ends
Normal Google logo stays there for a few seconds
Loading bar appears
Loading bar stayed there overnight (phone doesn't get hot or anything)
Is there any way to:
Enter safe mode properly
Start a terminal in recovery mode (like TWRP) to use the mm module to disable Magisk
Have an on device file manager (like TWRP) to manually delete the app
Delete files using adb
Get a normal adb shell (not sideload)
EDIT 1:
Starting "rescue mode" via fastboot shows the bootloader warning again, then the Google logo and then it's stuck (no color shift, no animation). Same for "recovery mode".
I cannot connect via adb/fastboot while the Logo is showing.
EDIT 2:
I managed to start "rescue mode" by doing the following:
Press power button
Press power button again (Entry selected: "Start")
Press both volume buttons and don't release them (I'm getting desperate here lol)
Bootloader warning (not skipped)
Rescue mode shows up (opened up Android, says "No command")
I can connect via adb, but "adb shell" or any other useful command says "error: closed"
EDIT 3:
Wtf, I got an adb shell by doing the following inside rescue mode:
"adb shell" -> Error
"adb pull /system/" -> Error
"adb pull /etc/hosts" -> Error
Phone restarted
Bootloader warning (skipped it)
Google logo, Animation & loading bar
adb connected
EDIT 4:
I entered the adb shell and used "setprop persist.sys.safemode 1" (source) (which registered correctly), but after rebooting, the phone still loads forever.
EDIT 5:
Turns out Safe mode didn't work because of Magisk/Riru/EdExposed or whatever, so I disabled Magisk by "touch /cache/.disable_magisk" (source) and now I successfully booted into safe mode.
Can you type up a more coherent guide to what you did? I'm facing the same problem and hoping to fix it without having to wipe my phone again! Thanks!
