Hi i was about to update my phone and setting it to factory in order to update it to Oxygenos last version since i still using oxygen2 (andoid 5) etc...
I was about to do a twrp backup however i do no thave enought space so i've read on internet that with twrp 3.1+ you can backup directly on pc. I've tryed to update twrp however its not working and not starting the recovery partition. I've read that : (3.0.2-1 and above for OxygenOS 3.x and above) (3.0.2-0 and below for OxygenOS 2.x and below) however i need the updated version to backup directly on pc what can i do? some advice? i've looked for a modified version of twrp 3.1 for oxygenos2 but i did not find it :S
Before you do this, update TWRP via these instructions
https://wiki.lineageos.org/devices/oneplus2/install
skip down to this line "Installing a custom recovery using fastboot" as you do not need to unlock the bootloader as it is already unlocked since you have TWRP already.
Do not make a TWRP backup, It will not be of any use once you move to OxygenOS 3.6.1 since the backup will be of Nouget (android 5). The best way to upgrade would be to follow the steps here http://downloads.oneplus.net/oneplus-2/oneplus_2_oxygenos_3.6.1/
Once you get to step 4, click the "View Instructions for TWRP Recovery" link then you can either dirty flash or clean flash the zip. I would recommend clean flashing, as in do the factory reset as mentioned in the second paragraph under step 4. However, do not directly flash the rom afterward, use the reboot option in TWRP to reboot into recovery then flash the zip.
NOTE: If you want to use Magisk to pass SafetyNet and have root, download the Magisk zip and flash after flashing the rom, or queue it to it flashes right after the OOS rom.
afterward let the phone boot up then do the setup. Once you have completed setup, enable developer settings and enable advanced reboot. use reboot into recovery to boot into TWRP
Now go ahead and make a TWRP Backup, This backup will be your Go-To backup if you want to go back to factory OOS 3.6.1 with the setup completed and Magisk already installed.
Not able to backup
The problem is that the last version of TWRP working on oxygenos2 is 3.0.2-1 and you can not make the backup directly on computer, i've traied toupdate twrp and it does not lounch however with that version of twrp (3.0.2) or before it works that was the point if there was any modified twrp for oxygenos2 and with twrp version 3.1 or higher.
TWRP v3.x.x doesn't work with oxygen 2.
There's no way to boot TWRP v3 without installing oxygen 3.
If you need to backup your files (pictures, videos, WhatsApp messages etc.) you don't need TWRP because it backups only your system and your apps.
So simply attach your phone to your PC and copy all your files.
If you need a copy of your system then you need to free some space on your phone and do a backup with TWRP v2
I've been getting bootloops after installing Magisk on my OnePlus 5 unlocked bootloader , rooted before at 4.5.15.
I directly updated it to 5.0.2 which resulted in many errors in the end had to flash it completely and then clean install the ROM .
The ROM works perfectly with almost no trouble.
I then flashed almost all Magisk versions I could get hold of (14.5,15.2,15.3,15.4(beta))
But none of them could get past the boot animation.
I've also flashed the no Verity mod file both before and after the flashing of Magisk nothing worked.
But everytime after all this I flash the Magisk uninstaller and I get easily get back to using the device but without root.
Anyone help me rooting this ?
The ROM has been downloaded from official OnePlus website and the twrp I'm using is the codeworkx version.
First do this then tell me how it went.
1. Boot to fastboot and flash twrp-3.2.1-0-universal-codeworkx-cheeseburger.img via command window, make sure you have adb installed on pc.
2. Then boot DIRECTLY to twrp.
3. Dirty flash OOS 5.0.2 over your current rom in twrp and then wipe dalvik and cache.
4. Then boot into fastboot DIRECTLY again and flash twrp-3.2.1-0-universal-codeworkx-cheeseburger.img again.
5. Boot into twrp directly and flash Magisk 15.2.zip
6. Finally boot into the system.
7. Optional: then you can go ahead and update Magisk via it's own flash tool.
I'm already on 5.0.2 so do I dirty flash it again?
Hi,
I was updating my OP6T to the new version (Magisk + Xxx NoLimits), but after the reboot post-update the device started to reboot to recovery after it booted. So I've tried to delete Magisk but the problem was still present, so I've decided to download the latest Oxygen ROM from the OnePlus and flash it from TWRP, but after flashing, the device started to always boot to recovery (before the OnePlus boot animation).
At least i tried to restore a nandroid backup of 1 month ago (System, Boot and Data), but still the device after the restore still boot to recovery before the boot animation.
I've only tried the system reboot (I've not tried to force boot another slot).
Do you have a solution to try before formatting the internal storage?
Thanks
Edit: After unistalling magisk and reflashing it again, now the device boots again, but immediately after (when the lock screen appear) the device reboot automatically to recovery again
Try this:
- in twrp , dirty flash the rom you are using (Oxygen os)
- factory reset
- flash twrp (the latest the better)
- flash Magisk 19.1
Reboot to system.
If this not working, Format data will work.

TWRP Users
1. Boot into TWRP and Flash the Latest Magisk Uninstaller
2. Flash the latest Full Oxygen OS Zip
3. Flash the TWRP installer Zip
4. Reboot to RECOVERY to make sure TWRP stays and continue to root.
5. Flash the Latest Magisk to maintain root
6. Reboot System and Enjoy the latest firmware without any data loss

I am guessing you skipped the first step...
Try this:
Flash the OTA zip
Reboot (you will be unrooted and with stock recovery)
Boot to TWRP through ADB
Flash magisk unistaller
Reboot
Boot to TWRP through ADB
Flash OTA zip
Flash TWRP
Reboot to TWRP
Flash magisk

I don't have the OTA but the full rom, isn't simplier to update with the full ROM?

Ok, I've done this and actually is even worse, the device started to boot in recovery again and TWRP doesn't recognize that the internal storage is crypted, so i can't even access the internal storage (it shows only strange folders), so, now I can't flash the nandroid backup anymore.
I also mean FULL rom .zip.
Format data in twrp or in Fastboot. Or use MSM tool .
https://forum.xda-developers.com/oneplus-6t/how-to/tool-6t-msmdownloadtool-v4-0-oos-9-0-5-t3867448

So I've to Full wipe and then adb sideload the ROM? Because at the current state I can't even boot the device, it always starts in TWRP
Edit: I've also tried the blue_spark's version but nothing changed, TWRP can't recognize the encrypted storage
you can try this first.

When you're saying you're flashing the full ROM after wiping, are you meaning the xxx no limit? If so this isn't an os rom it's just a magisk module rom that's an add on to oxygen os. You need to wipe and flash the latest oxygen os rom, stable or beta which ever you're using, then flash TWRP, flash your os again on the other slot, flash TWRP, flash magisk, if your system boots fine then flash the xxx no limits rom in twrp.

Maybe it was a Magisk module that caused it. I removed pixel module from Magisk and it done the same to me.
From 6T (purchased from oneplus.com), any time I follow the instructions for how to flash one of the custom ROMs, I get stuck at the bootloader with no working rom.
I was able to use the MSMTool to restore to 9.0.13. I upgraded a few times flashing OnePlus6TOxygen_34_OTA_024_all_1909112343_9fd6e0057b8747dc, which works, but when I try to flash a custom ROM, I cannot get past the bootloader. I say a few times because I've tried this for a few days now with no success.
Most recently, I used the Flash-all.bat inside 10.3.0-OnePlus6TOxygen_34_OTA_042_all_1912142031_d9ef3-FASTBOOT
I am currently on 10.3.0, with twrp-3.3.1-31-fajita-Q-mauronofrio installed using the fastboot flash boot_a twrp-3.3.1-31-fajita-Q-mauronofrio.img then fastboot boottwrp-3.3.1-31-fajita-Q-mauronofrio.img commands from fastboot.
I can then install Magisk 19.4 or 20.3, however again when I try to flash a custom ROM, I cannot get past the bootloader.
What am I doing wrong?
When you 'fastboot boot' twrp, you can't flash twrp as .img file after that..... (There is no recovery partition on our phone, only a boot one)
If you flash a twrp img it will overwrite boot partition with only twrp and no kernel... Basic knowledge. Once temporarily booted in twrp by 'fastboot boot' command you must flash the installer, meaning the .zip file.
Then reboot your phone in twrp and flash whatever you want
Always latest versions of Magisk, why flashing a deprecated 19.4?

I was having an issue with the boot command in 10.3.0, which is how I found the flash command, and using both of those seemed to work (at least get me into twrp).
Now I am able to just run fastboot boot twrp-3.3.1-31-fajita-Q-mauronofrio.img and it works.
I was using 19.4 because somewhere in here someone mention twrp not working with magisk 20.3.
I've had no issues with 20.3 and twrp, so I will continue to use 20.3
The steps I use to flash a custom ROM (after twrp is installed)
1. remove the lock screen security from the existing ROM
2. boot straight into recovery from the existing ROM
3. wipe Data, Cache, and Dalvik by swiping right to factory reset from the wipe menu
4. flash the ROM from internal storage using the Install button
at this point I've tried a couple of approaches including a reboot here to see if the ROM flashed, and also installing twrp right after flashing ROM so that I will have a working twrp install.
Either way, I can never get past the bootloader.
Am I performing these steps correctly?

I don't know I don't flash custom ROMs anymore, too old for that stuff and need my time for me.
There are specific instructions for each custom ROM it's better to ask in dedicated threads, some of them need to have OOS in both slots before, some of them need to be fleshed in both slots. Normally you eventually wipe things, flash the ROM and twrp to keep it, then reboot to twrp (necessary to boot on the slot where the ROM is actually fleshed, which is always the non active slot, which become the new active slot) and flash Gapps and Magisk ( because Gapps and Magisk can be flashed only in active slot) then reboot system

I've updated these instructions here, they are the same, just added to them really.
This is how I install Lineage 17. (If you are doing 16, replace 10.3.0 with 9.0.17, and the Q image of TWRP with the Pie image)
- Install 10.3.0 fastboot ROM again to start over, boot it once. Just to make sure everything is good.
- Reboot to fastboot.
- Boot the Q image of TWRP.
- Run the TWRP installer, reboot to recovery
- You backed everything up right?
- Factory reset (This is the slider at the bottom in the wipe menu).
- Format data. (This is the button that says Format data in the wipe menu)
- Do NOT wipe cache, do not Wipe system, do NOT Wipe Dalvik / ART, do not add anything else, Just Factory Reset and Format Data. After doing those two Reboot to Recovery one more time. You must do this after formatting data.
- Now transfer Lineage and TWRP to your phone, Windows / Linux should see TWRP fine as a media device when plugged in.
- Install Lineage
- Run the TWRP Installer.
- Reboot to Recovery.
- Install Lineage (You need Lineage on both slots, so yes run it again)
- Run the TWRP Installer (yes again).
- Reboot to Recovery.
- Install Gapps if you want them.
- Install Magisk 20.3 if you use Magisk. I used 20.3 it works fine. (20.4 also fine) Do not install modules or other add ons at this point. Boot once and go through the setup and everything, then install your add-ons.
- Be aware the phone will restart once, then Lineage will start up and all will be good.
From that point on updating should just be like normal :
- Reboot to recovery
- Flash Lineage.
- Flash TWRP Installer
- Reboot to Recovery
- Flash Gapps. (Assuming you use them, if you installed them once you must continue to install them or do a clean install)
- Flash Magisk. (If you use it)
- Reboot to system.
- No loss of data, or anything.
- No need to flash anything twice etc.
I've posted similar instructions here. It was just for LOS 16, same thing essentially though.

Sir, apology for being an old noob, I am on OOS 10.3.2 TWRP 3.3.1-32 can I follow the above guide? If Yes,
Why aren't we using the "Lineage Recovery" provided in "Lineage OS Downloads" page?? If we use it, will the above instructions change ? What are the cons of using it?
Sorry again for asking!! Can you please share me the Link to Open Gapps which Will be suitable in my scenario ?

Historically Lineage / CM recovery was hit or miss, or TWRP or other recoverys worked better. To be fair I haven't even tried the Lineage recovery. So maybe that is no longer true? Right now, I know TWRP works. The updated instructions link up there has links in it, FYI, link OpenGapps. OpenGapps can be found here. You will be using Arm64, Android 10 obviously.
Since you are already on 10.3.2 (I assume you were on 10.3.1 before) you should be good to skip the step about fastboot ROM or install OOS, and you already have TWRP., so you should be able to go right on to backing everything up, wiping everything, and installing Lineage. (So you can skip the first few steps)
Anymore questions feel free to ask.

First of all, thank you very much for your time and explanation.
Sir, so i will proceed as follows:
* Boot into TWRP Recovery
* Perform "swipe to factory reset" & "swipe to wipe data"
* Reboot to TWRP recovery again
* Flash LOS 17.1 on slot A
* Reboot to TWRP recovery again
* Flash LOS 17.1 on slot B
* Reboot to system
Sir, please check are my steps correct? If not,
From which step( steps mentioned in your guide) should i start?
Last query is, which GApps zip will be best for me, micro/nano/pico/tv stock, If i want max coverage of google?
Very sorry for knocking you repeatedly!!!

Your starting point is correct. However make sure you don't miss the re-install TWRP after flashing Lineage each time, and the second time you need to flash Gapps before you reboot to system.
Personally I always do Nano. Anything else you need (that would be included in Micro) can be installed from the Play store. Nano at least includes all the things that can't be installed from the play store.
Pico has the least in it. TV is for TV devices. On OpenGapps there is a box next to each package you can click and it will tell you exactly what is in each package.

Sorry for the necropost, but this also works for TWRP 3.6 and Lineage 18.1. I initially had a problem with the default TWRP for my 6t. During the initial TWRP fastboot the version on their site caused a firmware error which I could just barely get out of, but it screwed up the system boot process in some subtle way that even the fixed version of TWRP (found on this site) couldn't solve.
After trying your instructions above, it didn't work the first time because of the screwed up system boot. It just kept trying to boot to recovery. I suspected a firmware error and was almost going to do an mcmdownload soft-brick rescue. I tried one last thing, using the TWRP on the system to sideload the stock ROM. That worked and patched up the system boot process. Once I booted and ran through some basic initialization to make sure developer options were properly set I followed the above instructions and it worked nearly flawlessly.
One strange thing. After I installed Lineage 18.1 and TWRP to both partitions (as well as Gapps / magisk), it rebooted to system and almost booted without incident -- except a large circular logo popped up that said 100% and stopped. I figured that that meant someting completed properly, so I powered off, waited 10 seconds, powered on and then the Lineage green system initialization spinner came up for a few minutes and it went through the user initialization sequence.
Thanks. I almost gave up and bought a new phone.

- Install Magisk 20.3 if you use Magisk. I used 20.3 it works fine. (20.4 also fine) Do not install modules or other add ons at this point. Boot once and go through the setup and everything, then install your add-ons.
- Be aware the phone will restart once, then Lineage will start up and all will be good.
From that point on updating should just be like normal :
- Reboot to recovery
- Flash Lineage.
- Flash TWRP Installer
- Reboot to Recovery
- Flash Gapps. (Assuming you use them, if you installed them once you must continue to install them or do a clean install)
- Flash Magisk. (If you use it)
- Reboot to system.
- No loss of data, or anything.
- No need to flash anything twice etc.
I've posted similar instructions here. It was just for LOS 16, same thing essentially though.

OhioYJ, these are great instructions but it initially left me with questions about how that procedures would create duplicate installs on slot A and B. The answer is of course that the Lineage installer for the 6t knows about the dual slot setup and always writes to the inactive slot. Booting into recovery activates the inactive slot so that installing again after that installs to the other slot and now you have Lineage on both slots. The installer for TWRP always installs to both slots and is needed because Lineage always installs its recovery handler and you don't want that so you overwrite.
PS: TWRP has an option for installing itself after installing the requested package. Would that be just as good as installing the TWRP zip?
PPS: I had to do an 'adb push' of the Lineage and TWRP zips to sdcard for the installs. Unfortunately installing and slot switching makes the sdcard unavailable so you have to push the zips again. Is there somewhere I can write them to that I don't lose access to after a boot to recovery?
So, I searched the internet for a method to flash a CustomROM on the OnePlus 6T. But somehow none of them worked, so I worked on one myself that at least works for me.
There are 2 methods, use Method A if you don't have a custom ROM installed and still use OxygenOS. Use Method B if you are using a custom ROM and want to have another one:
Method A: From OxygenOS to CustomROM
1. boot in twrp
2. in twrp, do a factory reset
3. flash latest oos zip(flashable ota, link will be below)
4. flash twrp installer zip(i recommend mauronofrio´s twrp, link wil be below)
5. check current slot, then reboot in twrp
6. check if slot changed, then do a factory reset
7. flash latest oos zip
8. flash twrp installer zip
9. reboot recovery, and check if slot changed
10. factory reset
11. flash custom rom zip
12. flash twrp installer zip
13. reboot twrp(check current slot)
14. check if slot changed(if yes:it worked, if no:repeat)
15. additional: flash magisk&gapps
then,your rom is ready to use
Method B: From Custom ROM to another Custom ROM
1. reboot to twrp
2. in twrp, do a factory reset
3. then select advanced wipe: wipe system,cache,data. DON’T WIPE VENDOR
4. flash custom rom zip
5. flash twrp installer zip
6. check which slot you´re in
7. reboot twrp
8. if slot changed, everything worked
9. flash gapps and magisk if you want
then, your rom is ready to use
So, I hope I have spared you many problems and wish you much fun with your Devices.

Some of those steps are unnecessary. Like doing a Factory Reset each time you boot to TWRP as that will mess up your Encryption. And in Method B, you mention to Wipe System. DO NOT UNDER ANY CIRCUMSTANCES WIPE SYSTEM ON THE 6T. IT WILL MESS UP YOUR DEVICE. This is the method I use to flash ROMs.
1. Boot to TWRP
2. Flash the latest version of Stable OOS for your Device and latest TWRP Installer for your Device. -> Reboot to Recovery.
3. Flash the latest version of Stable OOS for your Device and latest TWRP Installer for your Device. -> Reboot to Recovery.
4. Flash ROM + TWRP ,Format Data (Go to Wipe, in the lower right corner Format Data, type in 'YES' and hit Enter) -> Reboot to System
5. After first Boot, You can Reboot to Recovery & Flash Magisk (Optional).
These are for EvolutionX that has Gapps built-in so you don't need to flash Gapps. Otherwise you can Skip the Format Data after ROM flash in Step 4, Reboot to Recovery, Flash Gapps and then Format Data. I use these and they have worked flawlessly for me. Also when switching from one AOSP based ROM to another, it's generally recommended to flash OOS Before.
