I installed the only TWRP I could find for Android 10 (Q) TWRP_C2Q_3.4.0-7.tar. Installed ok but I got these errors on formatting data in the recovery. Can some tell me what they mean and or is there an issue with the install.

If anyone is still willing to work with this rebooting to twrp thing I appreciate it. Because twrp is booting, I know it's not an issue with twrp but probably more something in the method I missed.

After I converted to usa super.img I did have to perform a factory reset using the stock recovery.

Il keep looking into it and perform a full flash from stock n9860 firmware.

Can people just lost off their original csc code and stock firmware they are on?
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] inningsdefeat500:
So beautyangel - I am curious, you said you rooted and did the carrier CSC but as per Mentalmuso says it breaks OTA so just wondering what was the point in going back to carrier?

Also, since this device is DUAL SIM - US Carrier doesnt have SIM Manager right so how does that work then if I have 2 SIM's currently

---------- Post added at 02:24 PM ---------- Previous post was at 02:20 PM ----------

From what I read, this happens when the device cannot go to a ROM and ends up in recovery

Thus my query about flasing kernel ( it asked where do you want to Flash? ) boot, recovery or super

I always picked boot
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] Mentalmuso:
Thanks. That's The firmware I have on my PC. I'll flash it and get the method refined.
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] Mentalmuso:
I dont know what is going on with you guys, but i just went through the whole process of flashing completely back to stock TGY TH1 firmware.

I then booted up to system to check my oem switch was present. It was. So i proceeded to download mode.

Flashed my TWRP tar that i redownloaded from the MEGA folder

After flashing was complete, i booted straight into twrp

Once in twrp i flashed the WETA kernel img, again downloaded from the MEGA folder

I formatted data, (wipe, format data, type "yes")

flashed encryption disabler

flashed magisk 20.4 zip

Booted, it hung on the samsung boot animation which is normal so i hard rebooted and it booted straight into system.

I dont know what else to tell you, except if you want to discuss deeper, and figure out what is happening, my guess is you need to perform a factory reset with stock recovery. Maybe doing this, before flashing the TWRP tar might help. Telegram thread is in the OP

yeah, i went ahead and root with magisk because twrp is unstable now
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] Mentalmuso:
Installation method updated

It seems important to perform a factory reset using the stock recovery to wipe out keystore and other samsung partitions before flashing TWRP tar from bone stock. So i have updated post #2 to represent this.

Follow updated instructions - it works ( main point being, when you flash Bone Stock, make sure Auto Reboot is OFF, then boot to Recovery manually and Factory Reset

Just download it through samfirm bud

And you have to start fresh and make sure you connect to internet after you wipe so your oem doesn't disappear

Then check its there

Then reboot to Recovery and factory reset

Then boot into download mode to proceed.

Good luck.

It should work.

Just FYI, when viewing this forum on mobile, signatures aren't visible. So the fact that you have a signature may not be obvious, let alone a link in it. I honestly forget people have signatures. I don't even remember if I have one, LOL.

The other US carriers have NOT been able to easily bypass the bootloader. All the US versions of the Note 20 Ultra are identical. Exactly the same down to the last screw and capacitor. The only difference is the carrier features, which install based on the SIM installed. Samsung bootloaders are no easier to unlock on any carrier version than the Verizon model. They're all the same device.

He's not misleading. Read the OP again.
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] Mentalmuso:

[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] Mentalmuso:
No. It would be misleading to say it's for exynos. I clearly state, this method and twrp will only work on an unlocked bootloader. Do you have an unlocked bootloader? No? Then it won't work. You do have an unlocked bootloader? Then it will work. Simple really. And the title says SNAPDRAGON!

Nope, you don't have to root before TWRP - you install magisk.zip ( google for it ) in TWRP and that is rooting it

OK so follow this

From Stock with phone off

VOL UP + Power

When you see Samsung Logo with triangle etc

Leave Power button, keep VOL UP pressed

You should see Stock recovery, if you don't then leave VOL UP - it should then go to Stock Recovery

Factory Reset

Power off

Go into Download Mode

Follow TWRP process in OP

Install Magisk.zip will give you root - he has no included it, just google it
