Actual custom rom flashing instructions ?? - OnePlus 6T Questions & Answers

This is my first Oneplus device and I just realized that in this device, in order to flash Custom Roms, you need to have a OOS installed beforehand plus not wiping /System partition.
So I was wondering which one is the best and quickest way to do a clean and fresh install from scratch, with the less amount of stuff from previous roms since wiping /System will end up on a bootloop.
Would it be something like this:
Starting from fresh and clean OOS latest version:
-Wipe /Data /Cache /Internal
-Flash Rom + kernel (optional) + TWRP
-Reboot recovery
-Flash Gapps + Magisk.
-Reboot System.
Is this the cleanest way to do it ?
I've seen @Koogly 's video but I dont know if theres a better way to do it.
Thank you all.

First time from oos zip
Flash latest stock rom oos
Flash twrp zip
Wipe data and cache
Reboot to recovery
Flash latest stock rom oos zip
Flash twrp zip
Wipe data and cache
Flash custom rom zip
Flash twrp zip
Flash gapps zip
Flash magisk zip if you want root
Reboot to system
If you are already on custom
Flash lastest stock oos zip
Wipe data and cache
Flash custom rom zip
Flash twrp zip
Flash gapps zip
Flash magisk zip if you want root
Reboot to system
If going from custom to oos
Back up all your internal storage pictures videos music etc
Wipe data internal storage and cache
Flash latest stock oos zip
Flash twrp zip if you still want to customize
Reboot to recovery
Flash latest stock oos zip
Flash twrp zip if you still want to customize
Flash magisk zip if you want root
Reboot to system
If you want a custom kernel on any of these methods I would recommend booting the rim first and going through setup process the rebooting back to to twrp after and flashing the kernel
Also you will want a USB c otg port bc after the first flash your data will be encoded. You can select the otg storage via twrp to make the process easier.
If you don't have an otg cable you will need to sideload each zip via cmd prompt with fastboot tools and sideload in twrp
After all flashes are complete and you boot the rom the encrypted data will no longer be encrypted on custom rom flashing if going back to stock oos rom you lose all internal data

Most ROMs threads have instructions in main thread and those should be followed first. Some ROMs may require some bits and pieces from original oxygen rom prior to custom install
Asoip for example

Is flashing oos necessary if we unlock bootloader?
I see instructions for lineage os dont mention flashing of oos bit they have the first step as unlocking the bootloader

You flash oos first so you have the correct vender and up to date files etc before flashing. Some ROMs require you to flash old oos versions bc their rom was based on that oos vender

Cannot update to 4.5.14

Hi,
I have a rooted OP5 with 4.5.13.
I tried to install the flashable zip (from here) via TWRP without wipe, but ended up in a bootloop.
I've restored to the nandroid backup, wiped data, and tried again. This time the OP5 managed to boot only to recovery.
I've verified the md5 of the file I've used.
Do you know why this is happening? Do you know how I can upgrade to 4.5.14?
Thanks.
Did you download the full ROM or just the update?
I tried both. I didn't succeeded to install the update (as it is not intended for rooted devices).
The full rom is what caused the bootloop.
If you are doing a dirty flash you wipe cache and system. If you are doing a clean flash you wipe cache, system and data. It doesn't sound like you wiped the correct partitions when doing your flash. You also need to flash Magisk or SU after the ROM flash and before booting up or you will lose TWRP and root. If your phone is decrypted for some reason you also need to flash a no verify zip or your phone will boot loop because OOS is made for encrypted phones.

Sanity Check on Flashing Stock 5.1.4

Ok, so I am not new to flashing rom but for some reason I am having huge issues trying to install clean stock OOS 5.1.4 rom. Just want to double check I am not doing anything stupid since I mainly been flashing custom roms (xXx rom mainly).
So I simply wipe dalvik/ART cache, cache, system and data (want to start off completely clan) then flashed the OnePlus5Oxygen_23_OTA_037_all_1807181258_7b4b6.zip file in TWRP.
I am currently on the latest blue TWRP and after flashing, it will try to boot but reboots back into TWRP. I have tried the zip file from a number of sources and they all do the same. Am I missing something here?
UPDATE: I did do something stupid after all. I forgot that my Oneplus was decrypted. So all I had to do was go into TWRP and go to Wipe and format data to re-encrypt it.

When starting fresh, wiping of internal storage should be considered. I recommended 2 guides here https://forum.xda-developers.com/on...nos-beta-1-android-oreo-t3710003/post77205633

Im not sure what instructions are you talking about but this isnt the first time i root my device.
Im using TWRP 3.2.1 since the last version giving me a little problems when trying to root. Im using the last magisk version.
About dirty or clean.. I first tried just flashing nornal from the OTA and then after it worked (no wifi or LTE) i tried to do factory reset and root again

Try flashing this first https://sourceforge.net/projects/cheeseburgerdumplings/files/16.0/cheeseburger/recovery/
Download ota again and clean flash it from the recovery.
It might be because your TWRP isn't compatible to Pie. Most people here including me tried codework's TWRP and it solved any of our issues.
Edit: after flashing magisk reboot your phone once more. (i didn't knew it before. I booted into my os and checked magisk app to see if root was successfull but it didn't show me. I wiped everything down and flashed magisk again. Same thing happened. Rebooted my phone and saw root was on )

Will try it on the weekend.. I had some problems restoring my previous backup so i rather be home when i do it

Edit:
Wait the wifi and the LTE problem can be caused by the recovery?

I would suggest do a complete clean install (wiping everything but USB OTG) and making sure you got the latest TWRP from blu_spark or codeworkx. Also flash it following these instructions:
[Clean Flash] For Users with an Unlocked Bootloader and TWRP Recovery:
- Download the full ROM zip from the downloads section above
- Transfer the zip to the root of your device's internal storage
- Only needed if you are coming from Oreo or if you use an old TWRP recovery that's not the latest and Pie compatible: Remove the compatibility.zip from the downloaded full ROM zip with either MiXplorer or Total Commander (not with any other tool!) on your device itself
- Reboot to TWRP recovery (make sure you're using siankatabg's TWRP if you're on Oreo or codework's TWRP/blu_spark TWRP if you're on Pie) and take a nandroid backup of your existing ROM
- Flash Magisk Uninstaller (recommended)
- From the TWRP menu, Wipe > Advanced wipe > Select dalvik-cache, cache, system, vendor and data> Swipe to wipe
- From the TWRP menu, Install > Select full ROM zip (modified one with compatibility.zip removed, in case you're on Oreo or unmodified one, in case you're on Pie) > Swipe to flash
- Flash the latest stable Magisk in case you want to root
- From the TWRP menu, Wipe > Advanced wipe > Select dalvik-cache and cache > Swipe to wipe
- Optional: If you wish to decrypt, format data via TWRP (please note that wiping the data partition, which we did in the 5th step above, is not the same as formatting it) and after that flash Disable DM-Verity and ForceEncrypt 2.0 (OP5-5T-Treble).zip from here
- Reboot

i ended up giving up..
im trying to do a clean flash
but the moment i flash the recovery and trying to go into the recovery
boom
black screen
i tried it multiple times both with codework 3.2.3 and blu_spark
Edit: Flash universal codework 3.2.1 does get me into recovery

For the "Clean" Install given that OnePlus5 doesn't have external microSD storage, will ALL data (photos, documents etc) on the phone be erased in Step 6 above?

No, it wont because all of that is stored in the Internal Storage. So as long as you don't check that, you will still have your data. However, I personally wipe everything including the internal storage when moving to a new rom. I prefer to start with a complete clean slate but it is optional.

Cannot root OP5 via Magisk

I cannot root my OP5. I have followed all of the directions unless I'm missing something. A week ago I previously switched to LineageOS but didn't like it so far. So I'm comfortable flashing ROMS.
1. I then downloaded the OOS official ROM, then loaded.
2. Update to most recent OOS (9.0.3) via OTA
3. Followed by factory reset to completely clear TWRP (which was downloaded via official website).
4. Downloaded TWRP
5. *Flash* No verity-opt-encrypt
6. Rebooted to TWRP
7. Downloaded Magisk zip, then flashed
8. Downloaded Magisk apk
9. Open Magisk app *shows* "Magisk is not installed*
I'm thinking maybe I've messed my phone FUBAR up or just completely doing wrong.
*sorry if this has already been answered as well or is posted in the wrong category*

The instructions you need to follow are here https://forum.xda-developers.com/on...xygenos-4-5-2-7-1-1-ota-t3627003/post72799040
You did not mention any file versions from rom, twrp, magisk.
What does the twrp log says? Are there any errors why magisk isn't installing sucessfully?

Sorry for not including the rom type. I was gonna try & run the official stock rom, while rooted. I know it was the TWRP from the official TWRP site "twrp-3.2.3-0-cheeseburger.img". Magisk was the most recent version a "Magisk-v18.1.zip". I don't think there were errors, but I can definitely try again.
I am going to try following those instructions. With me already being on "OxygenOS 9.0.4" via OTA update would I just need to cancel some parts? And to make sure that I flashed blu-spark correctly. I just drag then flash that while under TWRP correct?

Use latest Codeworkx twrp(link in the instructions) and flash it with your current twrp
Then flash magisk 18.1 and watch the log for errors!
Then flash no verity patch(if you were decrypted before and want to stay, otherwise please inform me!)
Your quoted instructions are the ones for clean flash the whole rom. DON'T DO THIS! there are also instructions for updating

I followed this right in order. And right when it was time to reboot, it was a black screen with a blue LED light. Looked it up, said that it's bricked/stuck in boot loop

Firmware issue. Your device is most likely on a firmware other then the one that twrp supports.
So what was the last oxygenOS firmware / rom you use and which twrp(file name) did you flash?
Within the flashing instructions it's written that you need to be on 5.1.7 before flashing 9.0.x

How to install TWRP and custom rom?

Please give me instruction!
What I have done to there:
1. Unlocked bootloader
2. Boot TWRP .img file
3. Install recovery ram disk from the same .img file
4. Reboot to TWRP
5. Install TWRP installer .zip file
6. Reboot to TWRP
7. Wipe system, data, dalvik partitions
8. Flash Havoc and TWRP installer
9. Reboot to TWRP
10. PARTITIONS ENCRYPTED/UNABLE TO FLASH GAPPS
I'm using TWRP UNOFFICIAL BY MAURONOFRIO.
What to do now?
I'm tired! Give me instruction!
You need to install the latest stable OOS to both slots before you install the majority of custom ROMs. There are multiple threads with instructions stating that. You also have to format your userdata partition when moving from OOS to a custom ROM and vice versa. You would need to backup your data beforehand. Worst case, the phone won't boot when moving to a custom ROM, but it will probably boot but have encrypted data.
Maybe this thread will help.
