Hi
Today I get my OnePlus 3T. So I did that, what I do with any new phone = TWRP and Root. So I...
1. Boot, download and install Oxygen OS 4
2. Fastboot unlock bootloader, flash TWRP (latest official build)
3. Reboot in TWRP and TWRP ask for password (never set any password for this phone, nothing! just start without sim and set nothing, only wifi for the first step)
4. Download SuperSU .zip and try to root - 0MB when I try to install SuperSu
5. TWRP > Wipe > Format data
6. Reboot and now I see (when I click on install) internal Storage (52100 MB). After that (dont flash SuperSU) just boot in TWRP
7. With OTG and USB stick I flash Oxygen OS 4.0 (full ROM with 1,4GB) > phone just reboot in TWRP.
When I go to
Wipe > Advanced Wipe > check Internal Storage > click on Repair or Change File System I get "invalid partition selection"
This also happen, when I check Dalvik/ART Cache. With System, Data and Cache no problems.
I have no idea what I can do. Over Google I only find some thread from Huawei and Samsung device, something with PIT file. Nothing to OnePlus (not One, not Two and not Three).

This question seems to keep repeating itself due to missing information on TWRP post about the latest official version being incompatible with OOS 4 encryption method, but that is the explanation. There is a beta release of TWRP in post 550 in that thread that is supposed to fix this.
Here's some spoon feeding for you
https://forum.xda-developers.com/showthread.php?t=3507308
Lookup post numbered 550 and it has a link to the unofficial TWRP update
What to do? Boot in beta1 and looks like the same... can flash OOS 4 but still the same problem.

First there are shortcuts for this, but I wanted to be sure I covered every step and where one is at each point, since it can be helpful for recovery or simply to see where one is. There are of course other ways but I just went through on a GM1917 and verified each of these steps, so that others do not need to piece together multiple threads. I'm assuming here we want to start from scratch, never a bad idea if you are willing to lose data, or else you have no choice and need to start from scratch.

I'm going to disable Encryption as well, because when written TWRP was not decrypting it and also because I find it a pain and simply put I do not need it on my phone, but those steps are optionally shown below, as well as root.
Next I'm doing this using files for the GM1917 (US/Internaltional), but you can replace both the fastboot version and the OTA for your device and the current version.
Before you begin: I'm assuming an unlocked boot loader
Be warned the steps below result in total loss of all DATA on the phone
Time: This takes about 45 minutes to an hour to complete.
I'm assuming you can get to fastboot mode, beyond that your phone can be seriously messed up, but as we are starting from scratch it should be ok.
Boot into Fastboot mode: (Vol- & Vol+ & power)
Use: 9.5.3-GM21AA-OnePlus7ProOxygen_21.O.07_OTA_007_all_1905120542_aa37bad-FASTBOOT to restore a prestine copy of 9.5.3 to slot A (only writes slot A)
Force it to power off on reboot (Vol+ & Power)
Reboot to fastboot mode (vol- & vol+ & power)
Now you should check which slot are you using with this command "fastboot getvar current-slot"
Now you should change the slot in use with this command "fastboot --set-active=*" you should replace with the slot is not in use, for example if you are using slot a the command will be "fastboot --set-active=b"
Now you should flash the twrp in the boot partion using this command "fastboot flash boot twrp.img"
Now reboot the device with in recovery mode scrolling the menu with the volume button and selecting "Recovery Mode" with the power button
Now we have TWRP on Slot B and 9.5.3 on Slot A we are on Slot B
If asked to decrypt, if not skip this step: Format Data, Then Internal Storage, Data and cache
Upload the 9.5.4 OTA Image: adb push OnePlus7ProOxygen_21.O.08_OTA_008_all_1905230032_1ef7fd0dc3.zip /cache
Upload the twrp image: adb.exe push test-twrp-3.3.1-2-guacamole.img /cache
Now Install 9.5.4: using TWRP to slot B
- Install -> /cache -> OnePlus7ProOxygen_21.O.08_OTA_008_all_1905230032_1ef7fd0dc3.zip
Go in advanced menu
Click on "Install Recovery Ramdisk"
Choose the recoveryimgfilename.img
Swipe to install
Reboot -> Select Slot A
Reboot Select Recovery
We now have TWRP on slots A and B. 9.5.3 on Slot A and 9.5.4 on Slot B
Back in TWRP we are now on Slot A:
Upload the 9.5.4 OTA Image: adb push OnePlus7ProOxygen_21.O.08_OTA_008_all_1905230032_1ef7fd0dc3.zip /cache
Upload the twrp image: adb.exe push test-twrp-3.3.1-2-guacamole.img /cache
Now Install 9.5.4: using TWRP to slot B
- Install -> /cache -> OnePlus7ProOxygen_21.O.08_OTA_008_all_1905230032_1ef7fd0dc3.zip
Go in advanced menu
Click on "Install Recovery Ramdisk"
Choose the recoveryimgfilename.img
Swipe to install
We now have TWRP on slots A and B. 9.5.4 Slots A and B
At this point you can boot up 9.5.4 Stock from Slot A by selecting Reboot System or we can root / disable encryption
To disable encryption (suggested if you do not care as it makes TWRP easier):
Optional: block the ROM from encrypting storage as we can not currently decrypt.
upload the zip: adb push Disable_Dm-Verity_ForceEncrypt_05.21.2019.zip /cache
- Install -> /cache -> Disable_Dm-Verity_ForceEncrypt_05.21.2019.zip
Note: this only affects the current slot (A in this case) which is fine
Reboot->System
At this point you have 9.5.4 Stock without Encryption on Slot A, With Encryption (and unused) on Slot B, and TWRP on Slots A and B.
Complete inital setup (I do the minimal at this point)
- Set a password, to verify if Dm-Verity_ForceEncrypt is working or not
Enable Developers Options
Enable Advanced Reboot in Developers Options
Note: My suggestion is to now power off and restart to ensure you have Wifi, as this is picky for some reason, and it is best to be sure.
Power -> Off
Power back on and verify that Wifi is still working, it should be.
If you want root:
Power -> Recovery
Upload Magisk: adb push Magisk-v19.2.zip /cache
- Install -> /cache -> Magisk-v19.2.zip
Wipe Dalvik
Reboot System
Finally: Verify that Safenet is passing in Magisk, it should be
You have 9.5.4 Stock with Encryption and Root on Slot A, With Encryption (and unused) on Slot B, and TWRP on Slots A and B. I hope having this in one place can help others, as I've tried to lay out exactly what I did each step of the way.
Parting suggestion: Maybe a good time to create a backup, one with EFS and Modem to just to be safe!

I would love to leave this device permanently decrypted as well for convenience, but I do want lockscreen security enabled.
On the 6T, if you flash the dm_verity disabler zip, the drawback is that you couldn't enable lockscreen security. You could set a PIN, but the system would never recognize it, even if it was entered correctly. So once your screen went off, you had to either format internal storage from recovery to boot into a no-lockscreen system, or use file manager in TWRP to manually delete the files to disable lockscreen.
I'm thinking that 7Pro is the same way. Can someone confirm?
Thanks

I saw o xXx Telegram that you can decrypt 7 Pro and also have lock screen security...
I too can confirm working lockscreen while remaining decrypted. Much appreciation to the OP!
Though I took a few shortcuts and used an otg USB drive, it still worked. Here's what I did:
(keep in mind that I am on 9.5.3, already had an unlocked bootloader, and had already used a patched boot.img that I injected via fastboot to achieve root)
To decrypt:
- downloaded dm_verity disable zip, magisk 19.2, and TWRP installer zip, and copied them to USB drive. Also, backup internal storage.
- used Magisk manager app to flash TWRP installer and Magisk 19.2
- reboot to recovery
- formatted internal storage (type yes, completely formatted the data partition and lost all media, photos, downloads, etc)
- twrp factory reset
- flashed dm-verity disabler zip and magisk 19.2 from otg USB drive
- reboot to system
Complete initial setup, repopulate internal storage with mefia (mp3, downloads, etc) from backup.
To upgrade to 9.5.4 once decrypted:
- download full 9.5.4 zip
- reboot to TWRP
- flash 9.5.4 zip and TWRP installer
- reboot to TWRP
- flash dm_verity disable zip and Magisk
- wipe dalvik
- reboot to system
Life is so much better decrypted.

I have tried your steps, but failed to decrypt the data partition.
I also tried different ways to flash:
* Disable_Dm-Verity_ForceEncrypt_05.21.2019.zip then Magisk-v19.3.zip
* Magisk-v19.3.zip then Disable_Dm-Verity_ForceEncrypt_05.21.2019.zip
* Disable_Dm-Verity_ForceEncrypt_05.21.2019.zip then Magisk-v19.3.zip then Disable_Dm-Verity_ForceEncrypt_05.21.2019.zip
but all failed.
My 1+7 Pro is GM1910.
Decryption is quite easy on my OnePlus 5T. Could you help me with some hint?

I suppose "decrypt" is actually a misnomer.
The more accurate description is "disable forced encryption on initial and subsequent boots".
You aren't actually decrypting your current data partition, you're preventing a BLANK data partition from being encrypted upon initial boot of a virgin operating system.
The reason I'm saying all this is the most common reason for the no_verity disable zip to fail is because users have not done a factory reset AND not formatted their internal storage (you have to type the word "yes" or you haven't done it) before flashing no_verity and magisk.
Also ensure your no_verity disabler zip wasn't a bad download (md5 checksum)
If this doesn't work, then you're left with what I've termed a "scorched earth format" (you select everything except usb drive to wipe in advanced wipe, and then format internal storage with a typed yes). You then install FROM A USB DRIVE the latest full ota zip + twrp on both slots with the appropriate twrp reboots, then magisk + no_verity, twrp reboot then magisk yet again and finally system reboot.

I have formatted the data partition, and the Disable_Dm-Verity_ForceEncrypt_05.21.2019.zip is valid.
Anyway I succeeded after upgrade to latest H2OS 9.5.5, with the same steps.
Thanks for your help.

Hello @tinyfish
Just dropping a note to thank you for the procedure. I wanted to achieve the same thing and I have been doing so through my own trial-and-error (and I'm actually documenting my steps as I go with the same intention of sharing to the community).
Apparently someone already beat me to it and I even used this written procedure. It worked for me. Although there are a few "differences" in the way I did it:
1. Instead of OOS version 9.5.4 I used OOS version 9.5.13 which is the latest Android Pie for the OnePlus 7 Pro as of this writing.
2. I used the latest version of the "DM-Verity and Forced Encrypt Disabler" zip which is version 10.20.2019 as of this writing. The older version didn't work and resulted to "Settings" app force-closing and thereby preventing me from booting. I didn't investigate but I assume that the reason is because the 05.21.2019 version is "older" than the OOS version 9.5.13 that I was flashing. I could be wrong. But it is important that I write it here so that it is made known and investigated by someone who has the time/knowledge/energy for it.
There are certain important apps that I use that couldn't run properly on Android 10, so I had to revert to Android 9 (Pie).
Thank you once again!
Each ROM thread has a different installation guide.
So I was confused and tried various installation methods.
"Step 1/2" and "Step 2/2" shown during installation rom, probably means installation on each partition (A, B).
If so, this is the most COMPLETE way I have tried
[Clean Install]
0. reboot to TWRP
1. Format Data, Wipe Cache
2. reboot to recovery
3. Flash latest OOS (necessary)
4. Wipe Data, Cache
5. Flash ROM, TWRP
6. reboot to recovery
7. Flash gapps, magisk (If you do not want to be encrypted, flash disable force encryption)
8. reboot to system
[Update]
0. reboot to TWRP
1. Flash ROM(+TWRP)
2. reboot to recovery
3. Flash gapps, magisk (If you do not want to be encrypted, flash disable force encryption)
4. reboot to system
