First I have an admission - I'm 82 so my memory is not as good as it was. I have been using smartphones for some years now including flashing recoveries and operating systems. This time, however, I have got myself into a real mess.
I have a OnePlus 6 and just recently there was an OxygenOS update from OnePlus which I installed in the normal OTA way. It was only a little later that I realised that I'd updated from Oreo (8.1) to Pie (9) and there was not a version of Xposed for Pie. I want Xposed so I decided that I wanted to downgrade to Oreo. It didn't occur to me that it would be any more difficult than re-flashing the previous version of OxygenOS. I now realise it isn't that easy or, at least, it doesn't appear to be.
Having flashed Oreo the phone wouldn't boot. It got as far as the boot animation and stayed there. I thought the best thing then would be to try and get back to Pie so I reflashed that. At least the phone now booted but I soon realised that some things weren't right. For example if I turn on wifi it turns off again after about two seconds so I can't use wifi at all.
I'm not sure what to do now. I do have a TWRP backup for both Pie and the previous Oreo. Would it be possible to restore one of those (preferable Oreo)? I'm a bit nervous about trying that as I'm not sure how much wiping/restore I'd need to do. There is the Vendor partition (I've not seen that before) and I would be very nervous about wiping and restoring the boot partition which now, I believe, contains the recovery.
I hoping that some kind person will offer some advice to put me on the road to recovery (No pun intended).
First of all, I'm impressed that you have done as much as you have (or even wanted to for that matter) at 82. Most older people I know (I'm 42 btw)barely know how to use there phones in the os, much less know what recovery is, lol.
Anyway, I'm pretty sure I've read that with you go backwards to Oreo from pie, you need to do a full wipe including storage. Did you do that?

grab this file. http://oxygenos.oneplus.net.s3.amazonaws.com/OnePlus6Oxygen_22_OTA_007_all_1805131952_O_MR1.zip flash that to be back on Oreo 5.1.5. this is the special roll back firmware.
also, this will wipe all data as well as internal storage. just putting that out there so you know before doing it.

No, it was something I was trying to avoid. I was working on the assumption that as going from Oreo to Pie didn't involve any loss of data/internal storage then going from Pie to Oreo wouldn't either.

As I said above I was trying to avoid wiping data/internal storage but if that is the only way then I'll have to do it. I do have a backup of my internal storage so I can replace that easily enough. Would my Oreo backup be of any use after the wipe to restore my original data setup? That version of OxygenOS was 5.1.11 so could I get back to that?
I thank you both for your very timely help.
P.S. Can you see anything wrong with this plan?
1. Flash the roll back firmware.
2. Install TWRP using Fastboot
3. Flash, using TWRP, OxygenOS v5.1.11 over the roll back firmware
4. Restore 'data' from my previous TWRP backup.
5. Restore internal storage from backup.

going from oreo to pie, no data loss.
going from pie to oreo, data loss.
that is how it is done. after coming back to 5.1.5 then you can go to 5.1.11

I think that's kind of understood at this point. However, I see no problem with restoring a Oreo backup once he's back on Oreo.

Almost. You are missing one thing.
1. Flash the roll back firmware
2. Install TWRP using fastboot
3. Flash, using TWRP, OxygenOS 5.1.11
4. Before rebooting, FLASH TWRP IN TWRP (This is important, as flashing 5.1.11 will overwrite recovery)
5. Use your TWRP backup
6. Do what you need for files you want on internal storage.
Don't forget to flash TWRP after you update to 5.1.11.
Not having much luck. I flashed the roll back firmware, and twrp, then rebooted but I got the boot animation again and it wouldn't go any further. I re-downloaded the firmware again, in case there was any corruption, and re-flashed it without flashing twrp but got as far as the boot animation again but no further.
Whilst in TWRP I used the file manager to look at internal storage and nothing had been wiped from that.
I'm not sure what to do now so any suggestions would be very welcome.

Fastboot working correctly - try flashing the fastboot Rom. Hopefully that will put you back to square one where you start over. Complete wipe though!

Use the fastboot ROM recovery. It works (I've used it twice) no data wipe.

That does sound rather hairy especially as I don't know which one I'd need to use. It does mention that it should not be used to upgrade or downgrade and I'm not sure that I, or my phone, knows which version is currently installed.
ADDENDUM:
I decided to try one more thing of my own. I wiped data and re-flashed the Pie version of OxygenOS then rebooted.
:laugh: It booted and seemed to be working properly i.e. I could use wifi and the time doesn't keep being lost.
I have now installed Blu Spark TWRP and restored my 'data' backup and I am now back to where I was before all this started. It isn't really where I want to be because I have no Xposed but it is significantly better than a non-booting phone. I'll just have to wait for a new version of Xposed (if such ever appears).
I really don't know why those other suggestions didn't work.
Very many thanks to all those who offered support; it certainly does give a morale boost.

Hi all I'm having hard time time in finding a way to restore back to stock.
I'm on OOS 5.1.8 with twrp official and Magisk
Can you please share how to format the phone completely and again install 5.1.8 or 5.1.6 oos?
Reason for this is poor battery life after last few iteration of updates. Need to see whether it fixes it.

Make sure you have your full ROM zip files on your phone. Disable secure lock screen in OS. Boot TWRP, backup data only. Wipe everything (data is optional) install ROM zip file, reflash TWRP zip, reboot. You can always restore data at any time after wiping it and it will be as you have it set up to your preferences. There aren't major differences in OOS versions so erroes shouldn't occur with data on any of them. If you want root, you can boot back into recovery and install magisk.

You shouldn't get a bootloop if you flash stock firmware via TWRP unless the file itself is messed up. Bootloop can occur if you flash magisk right away, I think. You have to reboot recovery before flashing magisk.
I have tried a couple of roms and I always end up bricking my phone when I try to move from one of the flashed roms back to OOS and have to resort to using msmtool and start over with 5.1.5.
Can someone please guide and advise on the best practices for flashing roms and then going back to stock. Thanks
Depends what roms you are trying to go from.. And what security patch the first rom is on.
When going back from let's say September to July you will have to format phone only to install oos again.
How have you done the procedure when you brick it?

Thanks for your kind reply, I format system, data & dalvik partitions & then install OOS and always end up with a bricked phone.
I believe format
Install twrp
Reboot to twrp
Install oos, install twrp
Reboot to twrp
Install oos, install twrp
Reboot to twrp
Minstall magisk
So you get it on both partitions

you mean encrypted? should be fixed with a format, or rather it's the only way afaik..
proper way is to take backups and keep off of phone, so that if you're going down android security patches(not sure what else, if anything triggers it), you'll have needed data on hand
When you switch from one rom to other Format data it's the way.
When you want to go back from Android 9 to android 8 you need to install a rollback rom.
Oos allways encripts youre phone and you will go back to Oos recovery.
Trying to get a clean backup before I go mucking about trying different ROMs, and I can't get it to work like I am used to. Just came from Nexus 5 for my wife and Onplus One for myself, backup was very simple. I am sure it's because I don't quite understand how A/B partition affects the backup, but I am not succeeding on solving this myself.
I am full stock updated to 9.0.3, unlocked no problem got BluSpark 9.93 TWRP and Magisk 18. If I make a backup, using default partitions or all partitions doest matter, when I restore it gets stuck on boot animation, and no matter what I do from there it ends up hard bricked. I have gotten quite fast at MSM Tool fix, and no major data loss because I have manual backup on computer, however I dont want to MSMTool every time I try a new ROM.
The ONLY restore I have succeeded at is to do a complete MSMTool fix, update back to 9.0.3, get TWRP and Magisk back in place, then restore JUST the data partition. that brings back my settings, apps, logins etc, but it is a huge hassle to do. I want to get to the point where I can say "meh I dont like LineageOS, lets just restore my clean Stock backup" and be done in five minutes.

Just backup data partition and flash your OOS zip when you want to return to OOS in TWRP. After you flash it, restore data and you'll be golden.

I tried that before but it either got me stuck in a boot animation or completely corrupted the phone with random gibberish named folders and having to MSMtool to recover. If I was on Havoc ROM, my understanding is that you cannot just flash the stock OOS zip over the top to return to stock.
Even if it did work that still takes out TWRP and Magisk, which is what i'm trying to avoid. I know it works different than it used to on the old partition setup, but is it possible to just swap back and forth between different ROMs using recovery backups? I would like to give Havoc and Liquid a week of use each but I dont want to nuke and restart my whole thing every time I switch. its fun to try other things but at the end of the day I still want to have a phone that doesnt need to be set up yet another time.

I only backup data, but I'm also decrypt, which helps. There really isn't a simple flip flop like you used to do. I backup data, then install OOS zip, flash TWRP, reboot recovery, flash noverity (for decrypt), magisk then kernel and reboot and all is the same as it was before.

thats a shame, it was really nice to be able to quickly change roms on my phone.
Regarding decrypt, I noticed one of my backup attempts was hampered when I had pin/fingerprint enabled before backup and since then I just make sure to remove all locking before backup. is this noverity thing used to strip the password from a backup or?
EDIT: so just to make sure I am understanding, when I do a backup in TWRP I can only really make use of the Data partition backup. and if i want to flash a ROM i basically have to do it as if it was a fresh install, get TWRP/Magisk back in, THEN restore my partition, every time I change ROM?

The best way to flip between ROMs is to take a data backup specifically for each ROM, but install the ROM as per instructions every time.
The noverity just maintains decrypt after you decrypt your data partition.
Restore your data any time while in recovery, and it'll be fine as long as it's data for that specific ROM. The order in which you do everything does not matter when restoring data and flashing the ROM.
EDIT: the order doesn't matter in regards to your data restore. Everything else matters in those steps, in their specific order, but you can restore data at any time as long as the other steps are in order.

The a/b partition is a failsafe that also makes updates easier overall. OOS is a solid ROM. I would recommend xXxNoLimits. That's what I use along with Smurfkernel. It's all preference.
I'm not an idiot when it comes to TWRP/ROM flashing, like I've been doing it for many years, but this whole TWRP a/b thing has me confused and I seem to be doing SOMETHING wrong every time I go between AOSP/OOS. Let me explain.
Starting off on OOS, I did the instructions correctly for flashing Havoc.
Flash rom>twrp
reboot recovery
flash rom>twrp
reboot recovery
flash gapps
Then I decided I wanted to give OOS another try. (I wiped data/dalvik cache beforehand) So I flashed the stock twrp flashable zips in https://forum.xda-developers.com/oneplus-7-pro/how-to/oneplus-7-pro-global-repo-oxygen-os-t3930585 - [OnePlus 7 Pro (5G)][ROM][OTA][Oxygen OS] Repo of Oxygen OS Builds
And thus, bootloop. Stuck on the OOS boot animation. I remembered in the Havoc rom thread that it says to never wipe System/Vendor (even though it sounds weird to not wipe system if you're flashing another ROM, at least coming from my other phones). And figured maybe I should have wiped system when going back.
So I used the ALL-IN-ONE-TOOL to completely go back to stock, reinstalled twrp, all that jazz. Made a BACKUP this time of boot,system, and data. Went back to Havoc. Tried to restore the OOS backup, and now I'm just on a recovery bootloop and am currently using ALL-IN-ONE-TOOL to go all the way back to fully stock. Again.
What am I doing wrong?
In the amount of time it took you to write this thread, you could have read one of the many threads discussing how to take OTA. I see you did not once mention Magisk, which is most likely your problem. Read and follow guide here

..? I'm not having any issue with how to take an OTA or installing Magisk, that's prbably why you didn't see me mention them.
I'm talking about if I leave OOS and go to Havoc, and then try to go back to OOS whether its through flashing a backup or flashing stock OOS, then I get stuck in a bootloop.

I gotcha now, when you flash a backup or stock OOS, are you retaining TWRP? Even with restoring a backup Magisk has be reinstalled. Now if you were on Havoc and went completely stock(with stock recovery) and boot looping , I would say something is messed up.
EDIT: Head back into HAVOC ROM thread and start from post 748 and read the responses. Your answer I believe is there.
Here's my question.
I'm curious to check out the Android 11 Developer preview. Currently, my TMobile phone has been converted to global with root and such. What I want to know is, if I install the Dev 3 Android 11 preview, and then want to go back to where I was on global, will I be able to get into TWRP to restore my backup of the Global? Will that work? Or would I basically have to start over?
Thanks everyone!
Probably would just have to download and flash the revert files listed on the developer page.
Yes android 11 is meant for global so is the downgrade
Right but that wipes the device. Does it also wipe recovery? I'm wondering if once I revert, if I can boot into TWRP and just restore from backup on Android 10

Backup for TWRP doesn't work fully. I wouldn't rely on it.
Upgrade didnt wipe mine, downgrade does. As far as TWRP, i dunno. (IN2017)

TWRP is not fully functional yet so I wouldn't try to restore from there. Upgrading wouldn't wipe phone but downgrading would. I would move all files from phone and copy to computer then restore after downgrade. Also TWRP is saved on your sd card so I think it would not delete the folder or contents since it's not a data file. Happy modding!
D'oh! I'm guilty and moved too fast. I got caught in a boot loop trying to wipe dalvik/cache in twrp. No biggie. MSM'ed back to stock.
TWRP isn't available for A11 yet so I doubt you'll be able to flash it while on DP3. Plus (I'm pretty any backup made on a newer OS won't work on older OS versions due to system changes unless you're only backing up and restoring data.
