How to downgrade from 5.1.8 to 5.1.7? - OnePlus 6 Questions & Answers

Hello, i'm currently on oos 5.1.8 with twrp and magisk installed, I'm facing battery draining and would like to downgrade to 5.1.7, is this possible? If so how can i do that?
Thanks

Were you on 5.1.7 before going to 5.1.8. If so, all you have to do is reboot to twrp and change slot to other 1. Then for me because i use custom kernel so i reflash kernel and magisk and you should be go to go.

I flashed oos 5.1.8 full OTA via fastboot, so i dont think this would work, correct me if i'm wrong

What i done.
1st, be sure to have a backup incase of the worst!
Have 5.1.7 zip, twrp and magisk on your internal storage.
Boot to twrp and install 5.1.7 zip,immediately flash twrp zip and magisk zip. Clear cache. Jobs a good one!!!

This wipes data, right? My phone with be restoring the backup once I do this process, correct? And by wiping I mean the OS and app data, not necessarily user data (pictures/files)

Nothing of mine was wiped. That's not to say it won't happen someone else and mine was just a fluke.

No wipe will happen unless you tell it to wipe.

wrong approach, it's always user space if battery drains except if there is a know bug.
absolutely top battery life here last time i got this was on nexus 5 and 6 after a lot of work with xposed and the likes.
in case you can't resolve this start to freeze apps and activate them one after another to see which was is draining.
of course there are other factors, normally i'd recommend a clean incremental install with frequent backups but then i'm reluctant to
recommend this now for this device even though it would work to find the culprit.
thing is that too many don't get the A/B thingy and some related differences under control yet and i don't want to be responsible for
even more hassle

I've had shocking battery life with the update to 5.1.8, hence having to downgrade and battery life is perfect again. I tried a fresh install, clearing cache, freezing apks, uninstalling apks, but no difference. I've filed a bug report with Oneplus and sent the log details to them of what they requested. It's a common issue in the OP forums.

To be honest it has to be specific to your device. I have two devices running on 5.1.8 since days and battery life is great.

I'll be using the twrp bootable image to boot to twrp. Will I still have to flash twrp zip after flashing 5.1.7? Or can I just flash magisk zip?

[Q] - No Calls or SMS OxygenOS or CM12

OK I am having a problem, when i rooted and followed the direction to install both OxygenOS or CM12 nightly I am unable to receive any SMS or phone calls except after a reboot. Once i reboot any saved messages come through and then once the phone sleeps it stops. I have rolled back to CM11S for the time being. Any steps or tricks to follow to get this issue resolved.
"followed the direction to install both OxygenOS or CM12 nightly" does it mean you are using Multiboot?

No just flashing either one I have this result. Not sure if I am doing something wrong in the process.
Steps:
Wipe all but internal
Flash Rom (then gapps if CM12)
Flash SU
Reboot

Well all i could suggest it, also please flash the CM12 firmware once. In theory oxygenOS and CM12 firmwares are compatible. So flash like this:
Install CM12 fimrware zip
Wipe System, Data, Cache, Dalvik etc without Internal memory
Flash Rom Zip
Flash Gapps
Flash SuperSu
and then let it boot and settle down. Before restorign apps or data, check for any issues again
seems to be sitting stable at the moment, will keep testing. but thanks for the input.

Great! Let me know if the bug persists. And be careful with firmwares. For CM12 roms, just flash the firmware once and you're good to go for all of then.

spoke too soon, after letting the phone sit ideal for a few hours and testing incoming calls\sms nothing came through. restored a backup of CM11S, for the week to have a working device. will keep trying to get to a root cause later in the week. will also open a help ticket with OnePlus to see if there is something I am missing as well since this happens with OxygenOS as well.

OOS 5.1.8 Restore back to original setting

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.

Flashing disaster!

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.

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.

Fix infinite boot without resetting data?

Hi,
after installing and uninstalling some Magisk modules, my device (OP6, OOS, blu spark TWRP, Magisk) randomly froze and after restarting, it keeps booting forever. I can still get into TWRP, so I tried a few things to fix this like:
Uninstalling and reinstalling Magisk
Flashing OOS, TWRP and Magisk again
Flashing just OOS,
but nothing seems to help. Is there a proper way of fixing this without wiping my data partition?
If there is not, how do I save as much of my data (like system settings, app data etc.) as possible from TWRP so I can restore it later?
Thanks for your help

I think you might have to wipe if you can't get your phone to boot after dirty flashing ROM. I would try flashing your boot. Img first in case it's magisk related problem. What ROM are you on?

No luck with that either, so I guess it's time to reset. What's the best way to backup and restore as much of my data as possible, like system settings and app data?

You can backup data in twrp but that might be the reason you can't boot. Google backup should of backed up most things. At this point you should be more concerned about getting your phone to boot.

Oneplus 7 Pro Bootloop after overlay install, still booting into recovery

Hi guys. Really need your help. Oneplus 7pro ,european version running 10.0.4 software, latest magisk 20.4 i think? and twrp. Everything was running fine until earlier when I installed a system ui overlay (one i've used before) and now my phone is in a boot loop. I can access TWRP, I've run the substratum overlay uninstaller zip and removed all magisk modules but still i'm in a bootloop. I've never had a proper bootloop before and i'm very frustrated. I've googled for the past few hours and removed everything I can think of that could be causing issues. Does anyone have some advice that doesn't end with me losing all my data? I have a backup but its from a month ago. I've never had this issue before so i'm a little stuck. Thanks
Edit. Phone is fully accessible through my laptop I can see all my files and connect to it. I just cannot get it to boot,surely its a simple fix?

Hi guys. Really need your help. Oneplus 7pro ,european version running 10.0.4 software, latest magisk 20.4 i think? and twrp. Everything was running fine until earlier when I installed a system ui overlay (one i've used before) and now my phone is in a boot loop. I can access TWRP, I've run the substratum overlay uninstaller zip and removed all magisk modules but still i'm in a bootloop. I've never had a proper bootloop before and i'm very frustrated.

Hi,yes I can. Its loading the logo now so i'll wait and see what happens. If that works then what should be the next thing I do?
Edit: Slot B seems to be bootlooping on the logo unless its meant to take a few minutes
Is there a way to recover without wiping my data?
So slot A sits on the caution device rooted screen then defaults to the fastboot rescue mode which allows me to select reboot to recovery which is twrp. From there I have full access to the phone but still not booting to system. Slot B passes the fastboot screen and hangs on the one plus logo just circling around. This is my first rooted phone and I haven't had any problems until now so I'm hoping its something simple because I didnt do anything big to cause it. Hopefully someone has some insight.
Can I just sideload the current version of OOS i'm running using TWRP and not lose my data?

Will I lost root or relock the bootloader? I'm trying to find the least destructive way to get back to what I had which was oos 10 with twrp and magisk.
Uninstalled magisk and was able to reboot. However reflashing it as i want to retain root makes it bootloop again. Any possible fix for this that isn't a factory reset and reroot?
I can't get substratum or substratum themes to work on any rom or stock, nothing happens after reboots.....or everything turns this weird orange theme. Then one time it corrupted the whole OS and I had to wipe.
try to Dirty flash the same Oxygen version
it will not Wipe your Data or internal storage

Thanks, i'll try this. Will I need to install TWRP again once I do this or is it unaffected?
Tried to dirty flash the same stock rom from TWRP but I don't think it did it properly. Can I dirty flash stock rom, flash magisk then try reboot to system?
Any help greatly appreciated.
