Oneplus 5T root problem

Hello all If any one can help me ,
I was rooted running rooted stock oxygen os before on my Oneplus 5T
after flashing Oxygen OS 5.1.4 Full Zip my phone is not rooting it gets in initial oneplus logo and freeze there without loading OS
Phone is working fine after Flashing Oxygen OS 5.1.4 Full Zip without any issue its not booting after flashing either SuperSu or Magisk
Steps which I follow are
1 Flash custom recovery I have tried both Codeworkx TWRP | Blu_Spark
2 after flashing recovery boot in to recovery flash Supersu or magisk
3 reboot
when I reboot if i Flash supersu it stuck on oneplus logo, If i flash magisk it reboot itself to fastboot so Os is not loading at all.
I have to flash full Zip again every time to get it working but then I dont have root access.
I have tried at least 10 times with different even old versions of magisk and supersu with out any success.
Is there any particular recovery or different version of magisk or superuse I need to flash?
your help will be really appreciated.

Try a different approach. Instead of installing recovery, just get phone rooted first. There is a way where you can boot into twrp (without installing it), and then flash magisk/supersu zip. If your phone is rooted, then you can install twrp later (or keep oem recovery)
This is how you boot into twrp (or any recovery): fastboot boot recovery recovery.img
Let me know how it goes.

As you said boot to recovery without installing it.
One problem currently I am installing recovery and flashing root. After that phone is not booting up in to OS it stuck on oneplus logo. Then I have to force off phone boot in to recovery and flash full os zip to get it working. I can boot in to TWRP because my os didn't load. Now if I use your method and flash root file and if phone won't boot to os that means I won't be able to boot in to TWRP again to flash full os zip to get phone working atleast without root. Any idea?

Huh, frankly I have no idea why you are facing this menace. I can just give two suggestions.
1. Try with older, more stable versions of TWRP and Magisk
2. Get yourself a custom ROM, most ROM's will work flawlessly after flashing root files
Hope for the best!

I usually switch from OpenBeta to LOS and back again. Here's how I switch back to OpenBeta (steps should work for official OOS):
1) Back everything on internal storage up. This one's important
2) Boot into official OOS recovery
3) Wipe EVERYTHING (this is why you need to follow Step 1)
4) Sideload the version of OOS you want. The instructions will be right there on the recovery screen
5) Boot into Fastboot and flash TWRP
6) Flash Magisk and (optional) Xposed

I don't know what to do.

How to install custom ROMs in Mi A2 Lite? When I try to install any zip in TWRP, it gets "Error applying update: 7 (ErrorCode::kInstallDeviceOpenError)", and if I install a GSI ROM by flashing system.img, it bootloops. Is there a tutorial of how to install TWRP and flash custom ROMs?

I suggest you to install Crdroid for our phone. It´s official and gets weekly ots´s.
Follow instructions on op and you are good to go!
Important: You need to use offrains twrp to get it installed:
Bootable: https://androidfilehost.com/?fid=1395089523397933315
Installer: https://androidfilehost.com/?fid=1395089523397933316
If you stuck in bootloop on Crdroid bootscreen, you might need to decrypt your phone by formatting data (all your data will be lost - incl. internal sdcard) and installing this

stuck in bootloader/recovery, can't flash ROMs.

Hello,
i'm stuck in a particular situation: i can use fastboot and i can flash recoveries but none of them can succesfully flash a rom. i want to go back to the stock Realme UI, my device is RMX1993.
i tried to follow the guide (https://forum.xda-developers.com/realme-x2/how-to/to-stock-rom-howto-t4014773) but the last recovery (rmx1993-sde20-stock_recovery-c05) can't flash neither RMX1993EX_11_OTA_1040_all_tSZ3Sf5A77NS nor RMX1993EX_11_OTA_1050_all_loALrMDyMrbs.
tried to flash trough orangefox or the last twrp that support ozip decription but the result is a "succesful flash" but a phone that does not go over the boot screen and it reboot.
i succesfully installed color os trough the proper old stock recovery and it said the installation was succesfull, but the problem was the same.
someone know where could be the problem?

You need to successfully flash Android 10 (Realme UI 1.0) before you can flash custom Android 10 roms.
Have you tried this guide: https://forum.xda-developers.com/realme-x2/help/how-to-flash-q-firmware-based-roms-t4115987
As for why your colorOS back up is not working i'm not quite sure...have you wiped your cache before booting to the color os backup?

Mi9Se TWRP loop after install a new rom

Hi everyone,
I try to install custom rom from miglobe with the mi9SE.
First step I successfully flash the bootloader with the custom TWRP ---> "TWRP-3.4.0-2-Mi9SE" (actually the file name is twrp-3.4.0-2grus.img download from github / redispade)
Then I boot on it, I wipe and hard reset everything, then I go to INSTALL and I select the zip file corresponding to the last miglobe rom for Mi9se.
The installation is done successfully. I reboot the phone, and now, the device always boot on the TWRP.
So I flash the device again with the mi flash tool and official globale rom.
Then I try again, trying to format all data and other option, but it's always the same, device boot on TWRP everytime after custom rom installation.
What is wrong in my installation process ?

1. Coming from any Mi-ROM, you've to flash vbmeta before new ROM.
2. Try SHRP from march instead.

so I tried installing Dot OS V5.1 on my a70q, I flashed vbmeta and then twrp using a guide on XDA and I can boot twrp and install the rom with no errors but after rebooting my phone boots into download mode and the only way I can fix it is by flashing the stock rom using odin
