[OnePlus 6T  Questions & Answers] teddyearp:
So, I decided to upgrade my OP6T with Renovate on it. Booted into TWRP (official from their website), did a Nandroid Backup. Now, I did remove my fingerprint and other security before starting. Flashed the full 9.0.14, reflashed TWRP, rebooted into TWRP, flashed Magisk, and then trid to boot into system. Got a bootloop where the phone was jumping in and out of the bootloader message. I tried to stop it by pressing power and volume down and it ended up booting into safe mode. I didn't like that so I booted into TWRP and restored my Nandroid. And that's when the fight started.

It won't boot into anything but TWRP now and everything is encrypted. I have been here before but last time, I got the device totally corrupt message and used MSM to recover. But that was within two weeks of owning the phone. Now it's been three months or so and I do not relish loosing all the pictures and other setting/changes I've made to my apps etc. I am NOT liking this decryption stuff.

So, is there something, anything I can do short of a fastboot rom and/or MSM tool that we all know will wipe out all data. What if I used the unofficial TWRP? Sideload the ROM again?

Any help is appreciated. I hope I didn't make this too long, but long enough to give enough detail of how I got here and that I somewhat know what I'm doing. Been doing this since the OG Motorola Droid almost 10 years ago.
[OnePlus 6T  Questions & Answers] Dr. Mario:
That's usually why backup is always a good idea and in some case, mandatory.

It usually depends on what TWRP version you are using, the recent unofficial TWRP can decrypt the whole /data directory no problem. However, it's possible to brick a slot, and be able to salvage your files in other slot. I have this problem, so I will have to figure out how to remove the encryption keys after backing up my stuff off the phone so I can have both slots functional (Slot A in my OnePlus 6T is bricked, so right now I'm on Slot B, with AOSiP, FrancoKernel and TWRP 3.3.1-6 on it). Dual-boot setup can be both your friend and enemy.

Nevertheless, I would give TWRP 3.3.1-6 bootable image via fastboot a try, and see if you could be able to recover your files from thereon.
[OnePlus 6T  Questions & Answers] mlock420:
I tried asking about this in the twrp thread no replies as of yet.... man I miss the days of epic4g touch (s2) days I could flash a rom , brick my phone and just restore my twrp or clockwork mod recovery back ups...I used to show off all the roms I had from back ups....I tried making a back up when we first got root and twrp for this phone and I definitely had to use msm tool to get my phone back up and running
[OnePlus 6T  Questions & Answers] teddyearp:
Me too. This a/b partition crap and force decryption takes all the fun out of trying new roms. So far it seems to be pointless taking a Nandroid if restoring it just soft bricks your phone. And from what I'm reading, flashing even a updated ROM almost always has to be done very clean, heck it seems like wiping your 'sdcard' is also mandatory. I'm just hoping the above suggestion of trying the different TWRP will allow me to at least get some stuff off my 'sdcard' but I secretly hope I can get into system once just to take a titanium.

Then it's wipe and trade for the oneplus 7 pro, root it and rom it once and call it a day.
[OnePlus 6T  Questions & Answers] ozzmanj1:
I can back up and restore nandroid no issue although I remove any pin code/face unlock/fingerprint prior to backing up. No issues.
[OnePlus 6T  Questions & Answers] teddyearp:
Just curious, what TWRP version are you on? I checked the TWRP website and they only have 3.2.?.? available there while mauronofrio (who is named as maintainer at TWRP) has 3.3.1.6 available in the thread here at XDA:

https://xdaforums.com/oneplus-6t/development/recovery-unofficial-twrp-touch-recovery-t3861482
[OnePlus 6T  Questions & Answers] teddyearp:
So. Today I tried to get this thing up and running. I went to the TWRP thread mentioned above and downloaded the latest files. Booted into bootloader, ran flashboot boot xxx.img and it booted into 3.3.1.6 just fine. The 'sdcard' was still encrypted so I couldn't copy the .img file and flash it via the newst instructions, , so I did an adb sideload of the installer file. That flashed just fine and I used TWRP to reboot recovery. Check. 'sdcard' still encrypted. Since this encryption issue seems to happen if you upgrade to a newer security patch and I had tried to do an nandroid restore of an earlier version, at the end I tried this (I did try those steps with 9.0.12 full ROM first, the version of my nandroid):

adb sideload of the full 9.0.14 rom (the upgrade that got me into this dang fix). Then adb sideload of the TWRP installer. Then adb sideload of Magisk since I have read that this needs to be done after TWRP to make your phone boot. Still no good. Won't boot into anything but recovery. Tried the 3.3.1.6 advanced 'fix recovery reboot' or whatever it is, still to no avail.

At least I still have the yellow exclamation point and not the red one. And TWRP 3.3.1.6 stuck, so I am at the latest TWRP there is, at least from what I know.

Any more help or ideas so I can at least boot into my system one last time so I can do some Titanium or even the OnePlus backup? I just have some data that to backup correctly, I need to be able to boot system without wiping my data.

Please?
[OnePlus 6T  Questions & Answers] sanjeev7:
This is the actual way to install or upgrade an OS

Boot to TWRP

ADB sideload oos 9.0.14

ADB sideload TWRP installer

Reboot system (Yes boot to system not TWRP..don't flash Magisk too now)

Let the phone boot

Go back to TWRP

Install Magisk
[OnePlus 6T  Questions & Answers] ebproject:
What you should have done is not flashed magisk, but booted back to recovery, flashed oos again so you have it on both slots. Flashed TWRP again, booted back to recovery then flashed magisk and then to system.

If you had encountered encryption, you could either start fresh with MSM and have to re-root. Or you could have wiped data and sideloaded OOS & TWRP from an OTG or PC so you wouldn't have to go through the process of using adb and re-rooting.
[OnePlus 6T  Questions & Answers] teddyearp:
Well, thank you two very much, but . . . . crud. Here's what I've done now:

per sanjeev7 I did this:

boot to TWRP (it won't boot to anything else, lol)
adb sideload OnePlus6TOxygen_34_OTA_021_all_1905281358_e3b3.zip
adb sideload twrp-3.3.1-6-fajita-installer.zip
Reboot system

It didn't boot to system, but booted back into TWRP so the additional step to sideload Magisk was moot.

So, then I went with what ebproject said above which on the surface looked more promising(?):

Boot TWRP
adb sideload OnePlus6TOxygen_34_OTA_021_all_1905281358_e3b3.zip
adb sideload twrp-3.3.1-6-fajita-installer.zip
Reboot to TWRP via phone
adb sideload OnePlus6TOxygen_34_OTA_021_all_1905281358_e3b3.zip
adb sideload twrp-3.3.1-6-fajita-installer.zip
Reboot TWRP via phone
adb sideload Magisk-v19.3.zip
Reboot System

Still would not boot into system, but just back to recovery (TWRP).

I know I could probably do a data wipe after sideload TWRP installer, but I'm being stubborn. I have an app called Fuel Log that I track all my vehicle expenses on. I can make a backup within the software that I can then copy from the 'sdcard'. And I also have pdf maps which I would like to be able to access my 'sdcard' to get the most recent maps from, but it would be easy enough to get the two or six newest maps since my last backup of the files from my 'sdcard'. And then there's my stock tracking app which I don't think I can backup my current stuff without doing a Titanium. Still could be done manually. So at the end of the day, I really wish I could get into system just once to backup fuel log.

None of it is the end of the world, as I am going to receive a Oneplus 7 Pro tomorrow. I just wish I could make as seamless a transition as possible. I do have Titanium backups from a few months ago for all these above named apps, but like I said, if anyone has any ideas, please let me know.

What if I did the second set using OOS 9.0.12 instead of 9.0.14 since that is the version of the Nandroid backup that I restored? Or, and this is a long shot I know, what if I flashed a different ROM altogether? I do know that dirty flashing a different ROM is almost impossible, but maybe?
[OnePlus 6T  Questions & Answers] Dr. Mario:
That's a classic symptoms of the loss of encryption keys for the /data directory (for some reasons, despite the dual-boot setup sharing the same /data directory, but uses two separate different keys for each slots - a definite bad idea).
[OnePlus 6T  Questions & Answers] ebproject:
Okay, to start off, before you started any of this what was you OS were you running?

That's what you need to try and sideload to try get the encryption back to normal because of the mismatch in security patches.
[OnePlus 6T  Questions & Answers] sanjeev7:
I replicated ur situation...and I have one cheat code for u

Boot into SLOT B if u r in SLOT A or vice versa!

The other SLOT is taking backup of current system before flashing successfully!! Try this!

---------- Post added at 11:31 AM ---------- Previous post was at 11:29 AM ----------

U can WhatsApp me on +918898340211

I would like to help u coming out! I have some experience in this!
[OnePlus 6T  Questions & Answers] Dr. Mario:
If you are not sure how to boot into either slots in Fastboot, here's the slot switch command;

fastboot --set-active=a

(Set to Slot A, substitute with B if you want to boot into Slot B.)

Afterwards, reboot (you can alternatively reboot into the bootloader by typing into "fastboot reboot-bootloader" so you can retry the data salvation via fastbooted TWRP).
[OnePlus 6T  Questions & Answers] teddyearp:
I was on 9.0.12. I did already sideload the 9.0.12 app then sideload TWRP (version I mentioned above) then sideload Magisk. I obviously took a bit of a break, rec'd my OnePlus 7 Pro last night. And of course, like any good Andoird'er I had to get it all rooted and stuff, you know, first things first, lol. So tonight I will probably try some more.

As in I'll sideload 9.0.12, sideload TWRP, reboot system and if it works I'll not really worry about magisk since I will be in.

Thank you very much.
[OnePlus 6T  Questions & Answers] teddyearp:
Wow, thanks. I don't have Whatsapp and as my signature says, I usually try to read read read, then after doing some steps with fail, I give up and post, lol. So I was done by the time I posted.

Like I said in my previous post, I rec'd my 7 Pro last night and got it ready to be set the rest of the way up, so tonight I will try this new method. Just curious, should I do the slot switch within TWRP or should I do it as Dr. Mario said and use fastboot to switch?

Thanks a bunch everyone.
[OnePlus 6T  Questions & Answers] sanjeev7:
U can simply go to TWRP and click on REBOOT...u will get option...SLOT A....SLOT B....try both the slots...one one time...I hope u boot!!

I was able to!
[OnePlus 6T  Questions & Answers] Dr. Mario:
Either fastboot or TWRP, you can use either methods of switching the active slots. TWRP is much easier though.
[OnePlus 6T  Questions & Answers] teddyearp:
Well boys, I can't say I/we didn't give it the old college try. Dang it!

So, I'm not going to put out as much detail as I did before since by now you know what I'm doing step by step. I'll point out that the 9.0.12 file (yes I used that one) I used is this one: OnePlus6TOxygen_34_OTA_019_all_1901231347_fb09dd2d4.zip

So:

Boot into TWRP

sideload ROM

sideload TWRP

Went to reboot menu (in TWRP) saw that I was on slot a, but just used the Recovery reboot button. Once back into TWRP, I went again to the Reboot menu and saw that I was already now on slot b. Repeated above and then sideloaded Magisk. Reboot. Back to TWRP only. Ugh! Tried it again, but instead of rebooting TWRP after the one slot, just changed slots without rebooting TWRP and repeated. Did not sideload Magisk. Still a fail.

I'm about done here, but there was one message on my computer within the command window that was shown after the second flash of the ROM on both tries:

ADB: Failed to read command: no error.

What a journey! Thanks guys. And/or girls if any of you are girls, hehe.
[OnePlus 6T  Questions & Answers] teddyearp:

Hey, as I can't really use LOS atm what is the next best thing for focus on privacy, or a decent rom with good privacy?
[Samsung Galaxy Note 9 Questions & Answers] bober10113:
id say the one that has the latest security patches
[Samsung Galaxy Note 9 Questions & Answers] ub4rz4ch:
So what's people's opinion on the best custom rom? I will have to check on latest security patches.
[Samsung Galaxy Note 9 Questions & Answers] TheInfiniteAndroid:
They're all pretty similar when it comes to "privacy", I'd recommend Pie based over Oreo & latest security patches of course, unlocking the bootloader in the first place to flash a custom ROM is already making you arguably more exposed than with a locked bootloader i.e thieves etc.

Best bet is to look for a ROM you like the look of then ask the dev any questions you might have, one feature I like to have present is "lockdown" in Android Pie to disable all biometrics and require a pin/password to unlock the device, if you're worried about someone gaining physical access to you device, maybe look for a ROM that includes that (if possible).

I'm almost ready to pull the trigger on a 256/8 varient of the k20 pro with the intention of just using the phone as daily with the Chinese Rom in A urope ,I know there will be other roMs but I just can't be arsed with all the modding about,getting too old and too busy to be messing,but love the look of the phone specs etc

Is there any downsides to using the Chinese rom,Im happy enough with the lack of band 20 and I understand the phone will get OTAs and there is English support

Are there any other problems besides the bloat which should be easy to remove, bit of fiddling for play store too I think

Should all apps work ok etc or anything else I should look out for
