Why doesn't OP8T OxygenOS recovery do much? - OnePlus 8T Questions & Answers

It looks like the OP8T OOS recovery doesn't really exist. About the only things it will do is wipe data or reboot to fastboot or system. No sideload.
All of the android devices that I own I have rooted as well as installed new ROMS on them and they had at least a basic recovery. Why doesn't OP8T OOS have a recovery like most any basic android OS? I really don't understand especially since OP has been very user-oriented in dealing with it's fan base. It appears the LOS recovery has these basic features. I expect other ROMS built for OP8T have a working recovery. Is there something unusual about the OP8T?

With the move to the A/B model, you now flash updates directly in the running system. So that functionality is no longer required in recovery. Which leaves just factory reset and fastboot as the two functions you can't do while the phone is still running.

Thanks. How do you install a new ROM then?

You use the custom ROM's recommended installation process.

You flash images, after unpacking them, with fastbootd.

So if you wanted to go back to OOS stock ROM from a custom ROM, you have to use the MSMtool? Did Android 10 or 11 or OOS change the partition structure for the OP8T? When and why did payload. bin become the container for the img files that used to be directly in the zip file? Is this all about the introduction of the seamless update and the a and b slots?

Have a read of this: https://source.android.com/devices/tech/ota/ab
Note that the OnePlus 8T uses this method - it even gets the updates from Google's servers.

OP3 to OP7P Questions

Some background: I'm coming from an OP3 which did not have this Slot A/B thing and you could easily just flash firmware going forward. I'm currently confused as to how custom roms will update firmware and such going forward.
I noticed there's 'systemless' roms now (like NoLimits), I don't really understand what the advantages/disadvantages vs something like Havoc OS are.
If I go with a custom rom, will I need to flash to OOS to update firmware then reflash back to the custom rom in the future?
I apologize if these are really newb questions, trying to find specific details with some of these keywords makes it really hard to find relevant information (and I've tried).
https://forum.xda-developers.com/oneplus-6/how-to/guide-noobs-guide-to-b-partitions-op6-t3816123
Link above is some info on A/B partitioning.
The benefit of systemless ROMs are that they are just Magisk Modules so installing and uninstalling is very easy. You don't need to boot into recovery or wipe anything.
Havoc is a full ROM and based on AOSP so wiping is needed, especially when security patches are different. Some people are decrypting their phones with the no verity zip but I won't say too much about that to keep things as simple as possible.
You don't need to flash any OOS firmware when on Havoc, and I think it's because custom ROMs have their own vendor image. More advanced users feel free to correct me if I'm wrong about this.
Flashing isn't really too different and I personally don't even think about A/B slots. You just need to remember to flash the TWRP zip file after a ROM flash to keep TWRP. And you also need to reboot back into recovery to install Google apps, rather than just after the ROM flash.
Custom kernels are now flashed last (after TWRP and Magisk).
This is how I've done it and have been issue-free.

From OOS 10.0.1 trying to install LOS 16.0 as a beginner and failing completely

I'm trying to install LOS 16.0 but it just won't work. I've tried using the TWRP 3.3.1-16 Q Unofficial by mauronofrio and it works that I can get into TWRP and can flash the rom and GApps, but then after that process once I try to boot into the OS it is just forever stuck in either fastboot or stuck on the bootloader unlocked warning screen. I did realize that I had to use fastboot flash boot twrp*.img because they disabled fastboot boot twrp*.img in the Android 10 update, but then am I supposed to reflash something on that boot partition now? The whole process is very confusing and the instructions from the LineageOS seem to not work at all. Is there anything I can do right now or is it just not possible to install this until TWRP, or OOS, or something I'm not knowledgeable enough to know about updates?
It's because you are using OOS 10.1 as a base (android 10) and you are trying to install Lineage OS 16 (android 9), so it's quite obvious why it isn't working. Try lineage OS 17 instead.

Lineage OS 17 won't work either. The developer intentionally used OOS 9 as base since fastboot boot command doesn't work yet on OOS 10. OP needs to downgrade to OOS 9 first, whichever of the two Lineage OS versions they wish to use.

I tried this. I downgraded to 9.0.9 and still the fastboot boot command is not working. Apparently this has something to do with the bootloader image itself not being downgraded?
I give up now, my temp phone I was using for holding backups for chat data just randomly wiped itself on havocOS and I've just lost years of chats and stuff and it's got me really down right now. They did fix the fastboot boot issue with today's 10.3.0 update but still nothing is working from any tutorial to get this thing to work on lineage, it just won't boot to it and twrp keeps having errors during flashing. This used to be so much easier on my older phones and I've installed this OS on about 5 phones now but OnePlus 6 just doesn't seem to work no matter what. I'm just going to go back to OOS and hope LineageOS 17.0 will get these issues ironed out by the time it releases. Severely disappointing and a waste of 3 days now but oh well
In my opinion, this is the easiest way to downgrade everything to OOS 9, including bootloader https://forum.xda-developers.com/oneplus-6/how-to/op6-collection-unbrick-tools-t3914109
After that, just unlock the bootloader again like usual and follow the LOS16/17 page's install instructions and you should be good to go.
I tried to install Havoc 3.5 while i was on 10 Ob2, unlocked bootloader and installed patched twrp, then rom. Got stuck in fastboot mode. **** hell i messed everything, later i found fastboot recovery rom from xda, flashed it, thank god it saved me. For me, msm tool was not getting connected, got an error like sahara xyz something... Then after refering to multiple xda threads came to know that most of the present 10 custom roms are based on oos android 9. Then again i used downgrade package from community, reverted back to ob 25 oos (pie), then as usual installation process. So if you are interested in custom roms, downgrade to pie. And again i wanted to go back to complete stock from havoc but unfortunately msm was not responding and fastboot roms wont support upgradation (im not sure), i went to twrp and installed stable 9.0.9 to both partitions + twrp installer. Then 10 oos stable to both partitions + twrp. Then booted up and installed Ob2 again from system updater, lost twrp on that process, then locked bootloader, so mow completely stock ? lot of work for nothing ? oos is better for me.. infact i got used to that. maybe i should purchase another phone to continue the momentum of getting latest updates. crazy oos influence ?

Really confused on steps to root / custom rom.. Help me please

I have the GM1910 version of the OnePlus 7 Pro
Ok so I had a stock OOS 10.3 on the 7 Pro I just bought used, went home and was super excited to get a custom rom installed. From my previous experience back in the day, I knew to USB Debug, OEM unlock, Advanced Reboot for convenience and followed the Havoc Custom ROm guide that said to:
1. Download the ROM, TWRP Installer, GApps, Magisk.
2. Wipe Data, Dalvik.
3. Flash the ROM, TWRP Installer (Use Unofficial Q compatible version, starting at 3.3.1.575).
4. Reboot to Recovery.
5. Flash the ROM, TWRP Installer again.
6. Reboot to Recovery.
7. Flash GApps (Optional), Magisk (Optiona).
8. Reboot and Enjoy.
Never Wipe System or Vendor partition.
After doing so, I first ran into an issue with Fastboot Mode being indefinitely stuck, but fixed that with a TWRP 3.3.1-75 version I downloaded, and was able to boot TWRP. After that, and following the guide above, I noticed it was stuck on the Havoc boot animation. I waited a good 20 minutes before realizing its likely never going to boot. I rebooted twice after that, waiting 10 more minutes each for a total of about an hour, thinking "Hey maybe it takes time". Nothing. I then tried flashing NikGapps for Android Q compatibility as latest Gapps on the OpenGapps website allows up to Android 9. I realized afterward that it was a n00b mistake so I downloaded and flashed the Beta Android 10 Beta Pico OpenGapps and Magisk Canary that also failed.
After that, I started searching around for finding a way to return to stock Android 9 to start over, thinking Android 9 had more stable support, so I downloaded and fastboot flashed the Android 9.5..11 GM21AA - Direct Download, but while showing the OnePlus stock boot animation, it freezes and then the device turns off entirely.
I'm currently waiting for the 9.5.13 Repack (taken from the Collection of Unbrick Tools thread) to finish downloading to see if I can use MSM tool to restore stock Android 9 and kind of start over. I would prefer to root / custom rom Android 9. I have no clue what I'm doing now, but honestly recall it being so easy back in the day before this A/B partition stuff and I would have considered myself to be not so much a n00b, but at least quite "experienced" but I guess thats completely irrelevant now hey!. Can someone please guide me on how I can fix this and get a custom rom booting? Thank you very much!
Update: I managed to restore to Android 10 using the Decrypted Oxygen OS 10.3 ZIP from the "Collections of brick tools" linked above, then rooted that stock OOS using the standard guide. I got Havoc Android 9 working prior but ran into tons of bugs so I just decided to stick to stock for now.

Unless there is something specific you need with a custom ROM, I'd stay stock and root.
I have EdXposed installed and can tweak most things.
I really need ad blocking and some basic customization.
I don't need a full ROM to get what I want.

I would have agreed with you yesterday, but I've used the phone for a few days and cannot stand the insanely rounded corners so I tried finding a work around. So far reducing screen height and getting rid of Oxygen OS's software rounded corners is the way to go but stock OOS doesnt give you the option, I'm hoping a custom rom will. Currently in the midst of flashing RR Android 9
Which boot slot are you trying to flash the rom on and have you tried flashing other roms? I know I've tried flashing havoc a few times and no go. I'm using blissrom right now and it works great until I get the rom I'm building and configuring and have data and messaging working lol

Question TWRP after updating to Android 12

Hi there,
I updated to ColorOS12 and accidentely rebooted, before flashing Magisk and TWRP.
My question is now: Can flash TWRP the ususal way WITHOUT losing my data?
Bootloader is unlocked of course.
TWRP doesn't work on Android 12 and flashing Magisk with recovery isn't supported anymore anyway.
Are you actually on ColorOS or are you calling OxygenOS ColorOS? If you're on OOS, you can get patched images here (there is a guide linked in the post too).
[DISCONTINUED][OOS & PA] OnePlus 9 stock/patched boot images
Now as we have TWRP for any A11-13 ROMs, there's no need for boot image patching, just flash magisk in TWRP. Hi! There's a great root guide here on xda by @zymphad and i thought i'd share the boot images for different OOS and Paranoid Android...
forum.xda-developers.com
If you're on ColorOS, you won't be able to use these images and will have to do the patching yourself.

I thought it's ColorOS, but now as you're asking.....
LE2113_11.C.48 is Oxygen OS, right?

Yes it is.
Ok, but flashing the boot.img only doesn't erase my data, right?
And after there is no c.48 available in the linked thread, I have to patch it on my own I guess?!

Just boot the C.47 image and direct install once it's up. As long as you don't flash it, it should work to get the device up and running with root to install.
And no, flashing the boot image doesn't wipe data.

Install LineageOS microg on OnePlus 8T

I am still trying to fully wrap my head around Android moving to Slot partitions. I am reading as much as I can and feel I have a better understanding of it but have tried to flash lineageOS with microg but ended up with a bricked device maybe due to not doing the proper steps to switch to the active slot? My question is if I have TWRP installed and currently on OOS 11, can I just flash the zip file for lineage OS or so I need to do something additional? The TWRP script states you have to boot into Recovery to switch active slots and flash additional items. I know if I flash lineage I will end up with their Recovery as well which I obviously dont want. Can I flash the TWRP installer after flashing lineageOS zip or no? Please help confirm or deny what needs to be done given my current setup.
Thank you all in advance for any help/experiences you can share about this.
