ah, I see, thanks a lot.

Yes, I saw that tutorial in the first posts of OP but it only concerns the data backup and another file includes instructions for the fingerprint backup and restore.

The attached file (unchanged from OP post) for fingerprint backup and restore is imho quite nice to fill in the missing steps.

May I ask if you can provide a step by step guide to make a full nandroid resp. the all-I-need-instructions to fully restore a former backup state?

Would you do that ?

I think because of the A/B slots it is not easy for those coming from former twrps not fully understanding what is going on with that A/B-slots and how to access them and how to check where to backup and where to copy the files - like me :unsure:*confused*
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] TuanLuong95:
I am use oxygen os. But after install twrp i can't delete file from system-ext
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] TuanLuong95:
Please fix it.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] XDAMaxe:
fix yourself by using a root-explorer if you want to delete files on protected parts of your device - if you know what that means. Better watch this before posting
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Lossyx:
system_ext is a read only partition, this is intended on OxygenOS. So I'm not sure what you're getting at. Besides, TWRP does not mount logical partitions R/W as far as I know, even if the partition is writable.

So there is nothing to fix.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
The data backup/restore process is not something you could work out other than by testing. That's why it's documented.

Backing up the system side is far easier and can be worked out by understanding what gets flashed in a custom ROM and understanding how virtual A/B partitions in super work. So it doesn't really warrant a how-to other than what I told you:

- backup boot, dtbo, and super.

- restore them to the same slot you backed them up from (because the super content is slot-specific) (edit: unless you've synced the slots, in which case of doesn't matter).
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] XDAMaxe:
alright, thanks for the heads up.

btw: did you already successfully restored a full system with before backuped data, boot, dtbo and super in your 8T with latest twrp (as of 26th July 2021) ? any special issues ?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
Haven't needed to restore whilst using 210726, but I've done it numerous times with the previous two versions.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] nujackk:
If I wanted to return to stock recovery, ( want to test a theory) How would I do that? Can i just fastboot flash recovery to both slots or do I need to do more?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tyler19820201:
Maybe one slot enough. Just fastboot flash recovery without _a and _b
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
You could use TWRP to flash a copy of stock recovery
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] nujackk:
Duh forgot about that, thanks
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] pratyush28:
I got these same mount issues with my recent flash. Had to recover using msm. Luckily I had read this post so I captured the logs. Only two partitions were checked while entering twrp, but I decided to ignore it seeing that the latest changelog mentioned this mount error was fixed and I had a full backup in case things went south.

The first SS shows the partitions that were selected by default on entering twrp, and the next one is when I flashed rom zip and then twrp installer.

1. I was on latest OOS

2. Tried to flash latest Derpfest

3. Twrp build date - 2021-07-26

4. Recovery logs attached (included kernel logs as well)

I have added both logs to my drive, idk why they arent getting attached in this post even after showing up as attachments.

8T mount error logs - Google Drive

drive.google.com

Edit - Followed same flashing steps but manually mounted the partitions. Got no errors and was able to flash the same rom successfully.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] fates13:
Latest TWRP build let me upgrade EvoX without mounting partitions without errors
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
Did you follow the instructions in post #2 fully?

Because your screenshots are taken half way through the process.

Those mount errors are normal until you've rebooted TWRP, which changes slots.

Having flashed a rom, the current slot virtual partitions are no longer available, hence those errors.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] pratyush28:
This is what I exactly followed. @iooxda had posted this above where you also had helped clear his doubts. So I felt this method is much better than formatting data first like mentioned in post #2.

- Switch slot

- Flash ROM + TWPR installer

- From TWRP, reboot again into TWRP

- In TWPR, format /data

- Reboot into System to re-create /data partition

- Flash Magisk.zip

Second time I did this exact same process but this time manually mounted all partitions and I didn't get any errors and could flash the same rom successfully.

I install the twrp-3.5.2_11-0-kebab-20210726-alpha onto my oneplus 9R only to realise now it is incompatiable. Touch screen does not work after entering twrp

What are my option if I just want to flash custom rom to my oneplus 9r? (Havoc OS/Lineage OS)
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tyler19820201:
kebab does not fit for lemomade. unified twrp has been finished for 8T/9R

use lemonade twrp only
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] osm0sis:
lemonade won't work either, totally different hardware and boot.img format.

Someone will need to target 9R specifically to get it working until someone can figure out what's missing in the 8T/9R unified kernel/tree. They could/should still base it off of this 8T tree though.

Maybe @YumeMichi would be willing to give it a try?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tyler19820201:
Is there any trick how to preserve twrp on OTA update? i do not want it to get replaced by Havoc recovery on OTA update but i have just realized at latest HavocOS OTA update that twrp gone.

I was asking the ROM dev about it but he said ask twrp devs about it...

However i would think this is ROM related issue not twrp...

Or am i wrong??
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
TWRP is a custom recovery. All ROMs for this phone include a recovery partition. So, it's not a rom issue. It's a user issue or, if TWRP supports flashing OTAs, a TWRP issue.

And I know that the TWRP devs are looking at a way to make TWRP persist when flashing ROMs.

But if you use TWRP and let the rom OTA update run whilst the system is booted, then keeping TWRP is your problem, not the rom's or TWRP's.

So, if you are rooted, you can flash TWRP again using dd in a terminal, or in Magisk. Or use fastboot.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] shouldvegotnote8pro:
Thanks for the response. I'm really not expert at this.

So I will be able to flash Havoc OS/Lineage OS without need for this twrp?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] osm0sis:
I also have a twrp ab addon.d script people could use.. check my Odds thread. 😆
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
See the Havoc thread for installation without TWRP.

But flashing with TWRP is probably simpler and it also let's you take backups and restore them (with a few extra steps).
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] xatornet:
Oneplus 8T user here. This TWRP allowed me to succesfully install PixelExperience ROM, while their custom recovery would not allow it. It freaking works.

You guys are getting there, nice job!!! Keep up the good work!!
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Fif_:
Since TWRP cannot flash stock (yet), how do you get back from a custom ROM to stock? Is EDL the only way?

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Fif_:
I've used payload_dumper to extract the boot partition from the full OTA zip in order to install Magisk.

How can payload_dumper help going back from custom ROM to stock?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tyler19820201:
you need to extract stock os zip and use the payload dumper method. i did it only on linux but never did on windows...
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Fif_:
Mind sharing a link or explain more?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tyler19820201:
try this method. it is for linux. it is txt but rename it to .docx after downloading.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
Use TWRP to backups data, boot, dtbo, and super while you're still running OOS. Then, when you've finished with custom rom, restore OOS using TWRP (follow instructions in OP) and make sure you restore super to the same slot you were on when you backed it up (edit: unless you've synced the slots, in which case of doesn't matter).
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] jfromeo:
I have an OP8T with LOS 18.1 and LOS custom recovery.

I wanted to flash TWRP, but if I try to disable "Update recovery" on my LOS flash settings, it says:

"It is impossible to disable Lineage Recovery updates on this device"

So, in each LOS flash, will I lose TWRP as LOS custom recovery will be flashed?

Thank you.

Hello. Can this recovery flash vendor partition?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
Interesting question. Vendor on this phone is a virtual partition (it lives inside the super partition). So it is flashed when you flash a rom. But, because it isn't a physical partition you can't back it up or flash it on it's own.

Of course I'd happy for someone to prove me wrong.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] optimumpro:
Understood. So, it would be possible to build custom roms with prebuilt vendor, as well as roms that would use stock vendor?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
You'll find that custom roms include vendor but I've never tried comparing it to OOS.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] optimumpro:
Not all of them. Some build vendor, some don't, instead they are using stock vendor. So, the first time, users flash latest stock to both slots, then they install a custom rom, which doesn't touch vendor. Oneplus 6/6t are a good example.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] noddledizzy:
Can someone please give me a quick short lesson about slots? What slot should I be flashing TWRP, custom roms and magisk, and GAPPS? There are two slots A/B from what I understand. My current knowledge about this slot seems like a recipe for brick.

This is my first modern smarphone. All my phones previous only need to flast twrp then flash custom rom. Now, phones have slot a and b to chose and if you chose the wrong slot, bam. bye bye phone.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
A good place to learn about this is to read the AOSP documentation (on a PC or in desktop mode on a phone) about OTAs and A/B devices: https://source.android.com/devices/tech/ota
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Laapander:
So now when the new update is released, it is possible to update using OOS local installer????

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tyler19820201:
New release? You mean 20210726 release like in the link in post #1 ?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Laapander:
New OOS release. I'm running OOS with TWRP and Radioactive kernel and I was just wondering becouse TWRP cant handle OOS flashing. But somebody wrote here about using local upgrade in OOS settings.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Laapander:
OK I continue my monolog.

I updatet OOS by local update in OOS. It worked. After that flashed TWRP in fastboot and in TWRP I flashed radioactive kernel. All good :cool:

Hi guys

I'm not a newbie but I've no more ideas to solve the lost nfc funktion.

My device is sweetin.

I didn't checked nfc before, in the meantime I've flashed cherishos, derpfest, arrow .....and octavios.

Some days ago I decided to try nfc in octavios but there were nothing to find ...no toggle in qs tiles ...no settings about nfc.

So I started to flash and test some ROMs. no success, again and again no nfc toggle. Tried some nfc fixes like nfc willow fix...no success.

All flashing was clean with format yes.

I've decided to flash stock sweetin 12.0.10 via twrp, no success. again with mi flash utility and I've locked the bootloader to get really factory reset. Flashing no probs, booting and updating to 12.5.2 no probs.

But no nfc button.

Unlocked bootloader again, flashed xiaomi.eu

Now nfc toggle is back but not working.

Flashing octavi os, nfc button still present BUT not working (can't activate nfc)

Hopefully someone can help with ideas suggestion solutions?

Thanks in advance

[Touch Pro, Fuze General] makuk:
Well, just an update, I took apart my HTC Touch Pro today and removed both cameras. It was slightly easier than doing the same on my HTC Tytn II previously.

I didn't encounter any tricky parts at all. I think HTC are manufacturing the phones in a really mass production factor so it makes it easier to produce.

[Touch Pro, Fuze General] makuk:
My workplace does not allow any cameras on the premises, including camera phones. Max one warning is given and phone/camera can be confiscated for good + criminal record if you do naughty things with the camera!

Disabling/covering up/removing lens doesn't count. Since the cameras have now been removed, they can't do me for bringing my HTC Touch Pro phone into the premises as there is no physical camera(s) inside my phone.

You can't find a cool phone nowadays without cameras!
