hi everyone... this morning i found my phone in twrp 3.2.3-0 screen... following is what i tried to boot into system

1. swipe to unlock
2. choose reboot option
3. choose system option

after system reboot... it first shows samsung galaxy note9 boot logo, then samsung logo for a couple of minutes, automatically reboot itself again for the second and third time and ended up in twrp screen again....

i have been on "N960_F_DS_N_DrKetan_custom_ROM_Q18" for several months now...

i would appreciate if someone could help me out getting back into system.... TIA and cheers....

in addition, in twrp, i have also tried rebooting using "power of", "recovery" option and ended up in twrp again...

Thank you so much @dr.ketan. I got Samsung Note 20 Ultra 5G as well but I have decided to keep it unrooted so that i can rely on it for banking apps and specially samsung pass and Spay. I love both of them. Android Devs are challenging us time and again by detecting root which stops us to use some of the banking apps when needed.
So I will keep using Note 9 for root related features and Note 20 for secure apps. I still find it full of features.
Thanks for all your hardwork for keeping our Note 9 Alive and up to date. 🙏🏻

What is issue with Google pay & Google password ? both are best alternative to samsung pass & pay.
 
What is issue with Google pay & Google password ? both are best alternative to samsung pass & pay.
There are some basic differences between both like I can add cards on SPay and use NFC tap to pay but nothing major that we can say is show stopper, this is why I was happy with both the alternatives on my rooted N9 for over 2 years.
Major reason of switch is this crazy root detection stuff from Google. Have tried everything but a couple of banking apps can still detect root and are unusable for me with Zygisk and hidemyapp too.

    Installation and Download


    Important :


    - This will void warranty.
    - As of now you will lose Samsung Pay and Secure folder forever if you root once, even unrooting won't help. (hope in future we can get it working on tripped knox device)
    - OTA likely won't work once you root device.


    Installation :

    If you are on stock ROM/Recovery, follow below said steps

    1.Enable Developer Option (settings - about phone - Software information - Tap 7 times on build number to activate developer option in settings menu)
    2.Enable OEM Unlock from developer option (If you don't have this option then read this you can't flash ROM before this option available.)
    3.Download and copy ROM File to Ext SD card, Use ES file/Root explorer or any similar to check MD5, it should be match with provided in download section.
    4.Download TWRP
    5.Switch Off device
    6.Press Vol down + Bixby and then connect device to PC to reboot to download mode, press volume up when asked to continue to download mode
    7.Download Odin and open it, Disable 'Auto reboot' from option menu of Odin
    8.Select TWRP (tar image) with AP tab of Odin and Start
    9.Once Successfully flashed, you will see 'Passed' in Odin tab
    10.Disconnect device and hold Vol down + power till screen goes off, Now immediately press Vol Up + Bixby + Power to reboot to TWRP
    11.Select to allow modification
    12.From TWRP, Select WIPE menu - Then FORMAT DATA - You need to type 'yes' to perform wipe. WARNING : This will erase all data including Int SD storage from device
    13.Once format device completes, go back and select REBOOT' Menu and then - 'RECOVERY', This will reboot to TWRP again
    14.Now select Install and navigate path to Ext SD card - ROM zip file, you have copied earlier
    15.Read installation instruction of ChangeLog post for vendor.img It may be available inside ROM zip or may need to flash separately, depending on version of ROM
    15.Let device boot, and read ROM specific Instructions below.


    If you are on CWM recovery and custom ROM already, Follow below said steps.


    1.Download ROM zip and place on Int Storage/Ext SD and check MD5
    2.Reboot to recovery and select factory reset and flash ROM zip you have copied in step 1.
    3.Let device boot,Read ROM specific instructions below.

    Some ROM specific instructions

    1. On boot, you will see a notification about don't use any app that requires root, wait till that notification to disappear. This issue explained in MustRead.txt file in download area. Also after first boot, wait for ROM Tool to open, it will provide option for some important fix.

    2. ROM doesn't have any CSC included as now csc have separate partition (ODM). ROM will not erase/flash/modify files inside odm partition it and you will have your existing CSC even after flashing a ROM

    3.Vendor partition may be included in ROM or available separately (Read changelog of version you are installing) .It is recommended to flash it specifically you are on different base.

    4.Since Pie version, OEM is pre-fixed with kernel patch and after flashing ROM, you may find OEM option in developer settings but it will be disable, it is actually because of hack/fix applied. In real case if it is disabled then you may not able to boot rom with TWRP. Simply ignore it.

    Read ChangeLog of ROM you are going to flash for any specific instructions. Link to changelog is available in next post below.

    Can I dirty flash (without factory reset) ROM? No, We don't recommend it. If you are able to handle consequences with dirty flash then proceed, but don't post bugs in forum without clean installing ROM.
    PS : Who can handle consequences of dirty flashing, they never need to ask this question in forum. ;)
