Hello folks,
After a few years using a Windows Phone I basically forgot everything about Android. I got a new Galaxy A510F and I'd like to know a few things.
I enabled OEM unlocking in the developer settings and installed TWRP via ODIN. When I try to boot into the recovery I only get the stock recovery and not TWRP. It is a carrier-device, but in the settings I can enable OEM unlocking. What am I doing wrong?
I hate Samsungs UI. Is there a Stock Android ROM like on Google phones?
Please help me :-/
all the best,
Albert
after flashing twrp don't start your phone after pass dialog, disconnect usb from pc & plug in charger then press vol down + power button together untill your phone switch off, when big battery charging simbol appear on screen press vol up + menu + power button u'll get ur recovery after some time
Hey,
Thank you! I eventually did succeeded with an older Version of Odin.
Is there a AOSP/CM/Lineage OS/etc. based ROM I don't know about? I just can't live with TouchWiz.
what odin u used , i am facing the same trouble with A310f
Samsung Stock Recovery has a defense mechanism flashing itself back if you leave Auto-Reboot in Odin ticked.
Untick it, flash, and then hold Vol Down + Power (mimics battery removal) and enjoy TWRP.
This is just a collection of tricks I have learned since owning my SM-T560NU:
Force Shutdown
While not recommended, there may be times in which you need to forcefully shutdown your tablet, such as a bad OS crash, or a bootloop. Most devices allow you to do this by just holding the power button. However I have found with my SM-T560NU, you must hold Power + Volume Down for about 5-7 seconds to trigger the force shutdown. Actually, this reboots it, which leads me into the next tip.
Recovery Mode
It is a common misconception that you need to hold Power while entering recovery mode or download mode. This is not the case. The actual keys for recovery are just Volume Up+Home. To try it yourself, tell your tablet to reboot normally from the OS, then hold these keys. You'll see it boots recovery, without needing to press power at all! The trick is to be holding the buttons when the bootloader boots. The power key is not needed at all unless the device is completely off.
Download Mode
Same as above, but Volume Down+Home.
Unlock Bootloader
If you are here on XDA, you are likely interested in customizing your tablet with a custom ROM, Kernel, or recovery. But it is important to remember to unlock the bootloader before attempting any customization. You can do this by enabling developer mode in Android (go to Settings, About, and tap the Build Number 8 times). Once enabled, go to the developer options (near About on the main settings) and near the top there will be an option to unlock the bootloader. This only needs to be done once. If you install a custom ROM or factory reset (via custom recovery), the "Unlock Bootloader" option may revert to "off", you do not need to enable it again. If you factory reset while still on the stock ROM, you may have to re-enable it, as Samsung's recovery may re-enable the bootloader lock. This is untested.
How to root N20 (N985F/N986B/N9860)
WARNING!
Before you root your device you must be aware that
This will void warranty.
As of now you will lose Samsung Pay and Samsung Pass forever if you root once, even unrooting won't help.
There are many features stop working when you unlock bootloader other than S pay/Pass like Samsung Health, Secure Folder, Galaxy Watch pairing issue, Issue connecting old gear watch (S3 or earlier), Google Pay etc but some ROMs are patched for all these mentioned features, you can use custom ROM or patch it yourself for stock ROM. Still you may trouble using some bank apps and these may fixed by adding these apps to Magisk Hide
There may be some knox features there which you may not able to use but I can't list those as I never used. Just Google It
Patched featurs are working today when writing this, No idea if it may stop working next moment/tomorrow or later
Also to note, once you root, you can't go back to "pre-rooted" state completely. It is one way!
OTA won't work once you root device.
ROOT with caution.
You can unroot & Relock bootloader after flashing stock firmware, but still your warranty flag remain 0x1 and most of countries it still voids warranty. Also after unrooting & relocking bootloader, some knox features never work again.
How to Unlock Bootloader
Follow below four steps to ulock the bootloader
1.Enable Developer Option
Open the Settings app on your Galaxy device.
Choose About > Software Information.
Now tap on Build Number 7 times to enable the developer option.
You’ll get a message “You’re now a developer.”
Now Developer option has been enabled.
2: Enable OEM Unlock
Go to the Settings app again on your device.
Navigate to the Developer option.
Enable the toggle next to OEM Unlocking.
Tap YES to turn on the confirmation dialog box.
3: Boot Your device to Download Mode
While device is booted → Connect device to PC → Select to Restart → As soon as device screen turns off, Press and hold Volume Up + Volume Down simultaneously OR In case device is powered off Press and hold Volume Up + Volume Down simultaneously and connect your device to the PC via a USB Cable.
You can see the warning message on your device and release the pressed keys.
Finally, press the Volume Up key once, and you will be booted into Download Mode.
4: Unlock Bootloader
Once device booted into Download Mode, you will see option to long press Volume up to unlock bootloader,Now, press and hold the Volume Up key for a few seconds., Here, you’ll get a confirmation whether you are sure to proceed.
Use the Volume Up button to reply to the confirmation.
This will erase all the data on your device and unlock the bootloader.
Once completed, your device will automatically boot up to the OS.
Now you have successfully unlocked the bootloader
How to root
Instructions for stock non rooted ROM
Use either samfirm.js, Frija, or Samloader to download the latest firmware zip of your device directly from Samsung servers.
Unzip the firmware and copy the AP tar file to your device. It is normally named as AP_[device_model_sw_ver].tar.md5
Install Magisk apk
Press the Install button in the Magisk card
Choose “Select and Patch a File” in method, and select the AP tar file
When done, copy patched file to PC
Reboot to download mode. Open Odin on your PC, and flash magisk_patched.tar as AP, together with BL, CP, and CSC (NOT HOME_CSC because we want to wipe data) from the original firmware.
Your device should reboot automatically once Odin finished flashing. Agree to do a factory reset if asked.
Install the Magisk app you’ve already downloaded above and launch the app. It should show a dialog asking for additional setup.
Let the app do its job and automatically reboot the device. Voila!
Upgrading the OSOnce you have rooted your Samsung device, you can no longer upgrade your Android OS through OTA. To upgrade your device’s OS, you have to manually download the new firmware zip file and go through the same AP patching process written in the previous section. The only difference here is in the Odin flashing step: do NOT use the CSC tar, but instead use the HOME_CSC tar as we are performing an upgrade, not the initial install.
Important Notes
Never, ever try to restore either boot, recovery, or vbmeta partitions back to stock! You can brick your device by doing so, and the only way to recover from this is to do a full Odin restore with data wipe.
To upgrade your device with a new firmware, NEVER directly use the stock AP tar file with reasons mentioned above. Always patch AP in the Magisk app and use that instead.
Never just flash only AP, or else Odin may shrink your /data filesystem size. Flash AP + BL + CP + HOME_CSC when upgrading.
PS : It is strongly recommended to make EFS backup once you root device and save to safer place like on cloud or PC

Mostly U version is Snapdragon with unlock bootloader and not rootable. Confirm first if you have unlocked bootloader.
Also last 3 digit of firmware is weird. Which device is this? Can you post screenshot of phone info?

What I guess, here unlocked means sim unlocked NOT bootloader.
Some people might need clarification. An "unlocked" phone is not the same as a phone with an unlockable bootloader. If it's the same pattern from the past several years of Note releases. All of the snapdragon US versions won't have the ability to have their boot loaders unlocked, therefore a root. This root method most likely applies to the non-US Exynos versions. If you live in the US, and ordered your phone through Samsung or any carrier, it will be the snapdragon version. I hope I'm proven wrong.

Hi thanks for the rooting instructions. I would like to know if you or anyone has gotten the option for s pen pointer under air commands in your note advanced settings? Jimmy is promo does but every other youtube doesnt have that option so im wondering what note 20 has it and what firmware? Anyone feel free to chime in
If you have rooted the Note 20 ultra 5g (Germany), can i start it normally or do you have to hold a key combination?

If you root with Method mentioned in OP, you should able to boot with root without using combo keys
I coming from the note 9.
If it's rooted, how do I update it?
(Switch from csc to talk (Vodafone DE to DBT) I know that has nothing to do with this topic )

Plz post your question to appropriate forum
ok a new topic, "how do i update a rooted note 20 ultra 5g" Ok I'll do it as soon as I have mine.
no one has the S pen pointer option?
Also have any of you signed up for beta 3.0 android 11 for the s20? Im guessing you guys have early access because the note 20 isnt even out yet.
Deal All,
My first goal (before rooting, try custom rom etc.) is to update with official rom from Android 4.4.2 to 5.0.2.
Samsung Kies ask me to use SmartSwitch which said "your device can't be upgraded" or something like that.
As said in title, I cannot enter in download mode. Pressing Vol+ Home and Power display the usual warning message, Vol+ to continue / Vol- to cancel.
Pressing the Vol+ just reboot the tab.
Entering Recovery Mode work fine with Vol- Home and Power.
I found some info about an eventual "OEM lock" to turn off. I followed instruction but no way, no "OEM lock" appear in Dev menu...
The tab as been wiped thanks to the recovery mode.
Any idea?
Thanks!
Edit: Resolved, it was a faulty volume button
i had th same thing but on lte version i just went to settings, delevoper options, end unlock bootloader or smthing like that it magically started working
Thanks for your reply. Basically those are instructions I followed without success:
1 - Turn off the phone.
2 - Turn on the phone by holding down the volume up button.
3 - The phone will enter official recovery mode.
4 - Wipe cache partition.
5 - Wipe data/factory reset.
6 - Reboot system.
7 - Log in to your Google account and your Samsung account.
8 - Go to settings and enable developer mode.
9 - Enter developer mode, enable "OEM unlocking" option.
10 - Now you will be able to enter the DOWNLOAD mode
I can't find any settings in dev mode meaning "OEM unlocking" or "unlock bootloader"...
I tried also to communicate with Odin, but the tab is only detected in regular mode, not in recovery mode.
I know it's kind of old device, but I can't be the only one, a solution should exist...
Ok, so it's resolved, and was even more stupid than you may think: my physical volume button was faulty and didn't catch each time when I pressed Vol+ or Vol-. Using a small tool did the trick.
[ROM][SM-J100H][09-06-2021][Stable] CyanogenMod 11 MicroG For Samsung Galaxy J1
Hi to all, I'm newbie with old branded SM-J100H with Android 4.4.4.
I would write rom I found in this forum to upgrade Android version.
I have no way to do this.
I've been searching for several guides on the net, none working.
I can detect device (only this) using adb.
I can't put device in recovery mode (tested several combinations of home-power-volume up bottons, none working).
I also enabled "developer options" menu, but missing "oem unlock", I've read "due to TIM operator branded phone".
Any ideas? Thanks.
for recovery mode boot into download when warning screen pop up press restart and hold recovery combination vol + home power
