Hello, I just flashed R11 in an Ultra N20 (N986B) and I have obtained a bootloop every 10 ", impossible to enter recovery or turn off the device.
Finally I have managed to enter recovery and reinstall the R10. I have downloaded R11 again in case it was a download corruption problem and I have tried to reinstall it with the same result.

I continue with the R10.

My version of TWRP is 3.5.2_10-A11_1_ianmacd

Flashed bootloader and modem?

And you think changelog post is just for decoration? Sorry

Really pathetic. Surely

I have flashed Modem and Bootloader following their instructions, no problem but now I cannot access TWRP.
Since ages, you needs to connect device to reboot to recovery
Connect device to PC - long press volume down +side key
As soon as device screen goes off, keep holding volume up +side key with still device connected to PC

Ok, solved.

In your guide to install Modem and Bootloader it is indicated that you have to disconnect to PC.

"Open Odin/Odin3 v3.14.4exe as admin
- Click on BL tab and browse to BL_DrKetan_*.tar.md5
- click on CP tab and browse to CP_*.tar.md5
- click on AP tab and browse to AP_*.tar.md5
- Put device in Download mode (Switch Off then - Press Volume Up & then Press Volume Down (Keep holding both) and connect device to PC with USB cable)
- Connect device
Select 'Start' on Odin
Disconnect when successfully flashed, it will reboot itself.

Thank you for your patience.

Thank you for your patience.
It's True, you don't needs to keep device connected to boot to system
For that you needs to first flash rom and then bl and modem.

I also have flash the AP; shown in the folder?
Doesn't bootloader zip have installation instructions? If it does then can you show me screenshot of instruction?
Also you are paying for not reading dev's instructions. Do you know everytime we do write changelog post that contains important information?

    After some workaround found a way to use TWRP on A12, I am in touch with Ian regarding this for final fix and public release.

    Edit : Made backup of SB1 and worked like a charm, yet restore not tested though.

    Samsung have F* up beta and TWRP no more working. Anyay succeed to root after lots of trial.
    I doubt development will be much impressive before get working TWRP. Custom ROM can be done but too much headache and needs to flash with Odin and no TWRP.
