Internal storage 0mb with TWRP - Samsung Galaxy S8 Questions and Answers

Hey people
Going by the title of this thread, you're probably thinking "Not another noob who can't be bothered to search the forum', but I honestly have been trying to do this myself for HOURS. This is what I have done:
1. Formatted data multiple times - TWRP shows unencrypted until I reboot recovery or system.
2. Flashed Magisk and ensured that 'preserve force encryption' is unticked.
3. Flashed 'no-verity-opt-encrypt-6.0'
4. Flashed 'G955FD_Root_for_OEM_issue_devices_V1'
I'm running out of ideas.... Can anyone help?

Are you using latest version of twrp 3.2.3.2 it should have the data mount/quota issues fixed in this version.

I fixed all of this by flashing Renovate ICE and selecting the fixed / modified TWRP during the AROMA setup.
The rom is perfecttttttttttt

Flash the latest TWRP with Odin, reboot to recovery and format data (where you need to type yes) and reboot once again to recovery.
Problem solved.

TWRP bootloop (even after flashing stock through LGUP)

I've decided to unlock bootloader, get a custom recovery and root my new LG G6 H870, so I've downloaded Melina TWRP v321 and Magisk v16.
Unlocking went well, then I downloaded drivers, unlocked debugging, "adb reboot bootloader" -> "fastboot flash recovery twrp.img" -> unplug usb -> boot into twrp by pressing volume down + power (with a tap) -> some weird screen about encryption popped up, but I clicked through -> and then I proceeded to install Magisk straight away, cause this guide said it'd not let TWRP stick if I didn't. After that I tried to boot into system and start the real fun. But it booted me back into TWRP. Again and again.
From there, I've tried Wipe -> Factory Reset, Wipe -> Advanced Wipe -> Repair File System for Data and System, Wipe -> Format Data, Advanced -> Fix Contents, but it all ends with twrp boot... I'm completly lost at this point. I've flashed/rooted a few phones before, but this one... it's a real nightmare.
I've also tried flashing a stock kdz (the filename is "H87011i_00_EEO_GB_OP_0108.kdz" for anyone wondering) through LGUP and redoing this stuff, but I end up with the same result. Please advise how to get it working.

Did you use uppercut when you flashed the kdz file? This is needed to successfully flash back to stock.
Seems it didn't work correctly.

Yes, I did flash through Uppercut (v1).
Since this thread started I flashed it once again, but this time I tried installing official TWRP v321. There was no weird encryption screen, but there were a lot of msgs (when installing magisk or doing a backup, for example) about being unable to unmount /system because it was being used. I did manage to install Magisk though and boot up the phone, but then when I tried installing Xposed, the phone went into another weird loop... but this time, it would get stuck on LG screen and it'd start heating up very fast. It stops heating when I restart using volume down + power into recovery. But I'm once again stuck... this is incredibly annoying, are aall LG phones like that?

How you installing xposed?
Install it via magisk module.
I had no issue.
Unlocked BL
Flashed Zefie TWRP (most stable and backups work)
Flashed fulmics
Flashed Magisk
Wiped cache and dalvik.
Reboot.
Works fine and flashed this over 15 times now no issues ever.

Did you also have that weird encryption message when flashing Zefie TWRP? Could you be more specific about your way? As in, you wiped cache/dalvik only once or after every flash? Did you wipe anything else? And yeah, I've just downloaded Fulmics and I'm at the installation screen, but I clicked System Information and it says my Storage Size is 5417MB with 104MB free... it reads SDCard Size correctly though. Should I be worried?

Starting from fresh, out the box.
Unlocked bootloader.
Installed Zefie TWRP.
Then added fulmics zip to sdcard.
Flashed zip, followed on screen instructions.
Wiped dalvik and cache.
Rebooted.
Takes a few minutes.
Boots up and done.
Magisk was packed into fulmics when installed.
I do NOT touch xposed. Too many issues plus I need safetynet for Google pay.

Yeah, I pretty much flashed stock firmware back and then followed basicreece instructions, along with flashing Fulmics, but I've got the 'official' Twp (v321). And everything's working so far, but I didn't touch Xposed so far though since Fulmics had pretty much all I wanted from Xposed. Word of advice for future readers though: don't bother staying on stock, too many problems. Fulmics is basically stock, but with some really neat options, and a ton of bugs and problems less.

HELP! SM -G901F, TWRP can't find storage partition to mount

Guys this is help less.
After rooting my device I followed some instructions to get the Lineage 14. I flashed a BootLoader and a Modem as instructed and went forth to mount USB in order to transfer the custom rom into the device. But this is where the problem is.
It says E: Cant find partition to mount storage. I've tried to reboot, wide, data, storage, system and cache and repair the partition I don't know what else to do.
Anyone else can help? Btw I am fairly new to this stuff so please dumb it down for me.
Another thing, when I go to reboot my recovery it says my device isn't rooted and asks to install superSu, however it was rooted before I entered download mode and started installing bootloader and modem.
Now I have no operating system in the device so i can literally only use Recovery or download mode.
Is my device bricked? I don't know. :crying: :crying:

If you can boot recovery, all is not lost.
First, are you sure that you flashed the correct bootloader/modem for your s5 model (G900 T, P, V, F, etc? Odin should not let you flash the wrong one, but anything is possible.
If Bl/modem is correct, them the next thing is to get the custom rom onto the phone.
-make sure you have downloaded everything you need (rom, root method(pref Magisk), gapps if wanted)
- boot into recovery, I'm recommending and assuming that you are using the latest Twrp, if not, d/l official Twrp for your model, and flash that with Odin
-In twrp select wipe, format data, just in case.
-now you should be able to mount usb storage, using the option in twrp
- now you should be able to mount your phone to your PC and transfer the rom, put it somewhere easy to find on the phone. also copy gapps and Magisk zips
-now, still in twrp, select install, select rom zip, select add more, select Magisk zip, also flash gapps at this time if you want to use them.
-click the button to flash
-click wipe cache/dalvik
-click reboot
-pray ?

Hey man! Thank you so much for your reply. I installed CPE1 bootloader and modem driver, honestly I don't even know what they do. Was this a wrong thing to do?
I rooted my device using cf auto root, then flashed the bootloader and modem using Odin. After that I (stupidly) tried to boot my stock OS and it was stuck in a bootloop.
Unfortunately I won't be able to try your instructions this till tomorrow evening but I'll keep you posted!! do you mind if I pm?
Edit: I was using twrp 2.8.7 I believe, could this have been the problem? Also I updated twrp to latest and tried micro sd as storage and flashed a Rom but the phone is still bootlooping

Ok I see you have S5 plus. I'm not familiar with that device to know which baseband it should be.
One thing you might try is to boot recovery and clear cache/dalvik and then try booting the custom rom.
If all else fails, you might try Samfirm
https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647
That should give you a stock firmware file to flash with odin.
You can pm if you need to, I don't own an S5+, nor am I a veteran flasher but I will try to help if I can.

Ive tried the suggestion you gave me, no success. However I honestly dont know if it could be my fault. I'm gonna flash the stock firmware and restart the whole root process.
Thanks for your help man!

Ok sorry I couldn't be more help
Oh, you don't need to use of cfautoroot anymore, you can just flash Magisk after the rom, and then use Magisk manager to manage all your root permissions.
So if you are going back to stock, I would:
-Flash stock in Odin
-probably boot stock once to verify (first boot takes long)
-odin flash latest twrp(uncheck auto-reboot, just battery pull after it says pass)
-power on phone with key combo to boot recovery
- format data
-flash rom/gapps?/Magisk
-wipe cache/dalvik
-reboot system (first boot will take long)
Hope you get your phone working again

Good News! Phone is back in full working order after flashing stock firmware. It was kinda scary though, I had to fix an error in Odin and then the phone wouldn't even boot up! Left it over night, booted it again and it worked fine Thanks a lot for your help, I'll try not to soft brick my device again

After first boot /data mount is gone in TWRP

I've got a SM-G950F, and succesfully flashed TWRP on it.
Wiped /data, after that i flashed dm-verity and force encryption disabler, everything was ok until the first boot into the system.
It booted up, and immediately after that i turned off the phone and booted into TWRP, and for some reason it couldnt mount /data again.
The tutorial i have followed:
Thanks for the tutorial to: jesec
Part 1 - HOW-TO FLASH TWRP:
1. In your ROM, go to Settings -> About device. Tap 7 times on Build number to enable Developer options.
2. Go to Settings -> Developer options and enable OEM Unlock option.
3. Download and Install Samsung Mobile Phones Drivers.
- Option 1: Download and Install Smart Switch for PC.
- Option 2: Download and Install standalone driver package.
4. Download and extract Odin (Samsung's Flash Tool) to your computer.
5. Download a .tar image of TWRP.
6. Reboot your device to download mode.
- Hold [VOLUME DOWN] + [BIXBY] + [POWER] for approx. 15 seconds.
- Read the warning carefully.
- If you agree, press [VOLUME UP] to get into Download mode. If you don't agree, STOP.
7. Open Odin and place that TWRP tar file in the [AP] slot.
8. Connect your phone.
9. Hold [VOLUME UP] + [BIXBY] + [POWER] on your phone and then press start on Odin.
10. Wait for the phone to reboot. DO NOT release [VOLUME UP] + [BIXBY] + [POWER] or you may not reboot into TWRP.
Part 2 - HOW-TO INITIALIZE TWRP: (for new phones)
1. If you completed Part 1 successfully, you should be in TWRP now. At this point, you will reach the screen asking you if you want to allow system modifications.
2. Select "Keep /system RO". (Don't swipe right or you may not be able to boot into system if you failed to complete next steps. However, you can swipe right to allow modifications if you are confident that you can complete next steps.)
3. Go to "Wipe" menu of TWRP and you will find "Format Data". Press "Format Data" and type "yes" to continue.
4. Go to "Reboot" menu and Press "Recovery" to reboot TWRP.
5. Download the latest dm-verity and force encryption disabler zip on your computer.
6. Transfer the zip to your phone.
- Option 1: MTP: Connect your phone with computer and just copy the zip to internal storage. (similar to how you transfer files when in system.)
- Option 2: ADB: Connect your phone with computer and run command "adb push /path/to/zip /sdcard/".
- Option 3: External SD: Copy the zip to an external SD and then insert the card to your phone.
7. Go to "Install" menu of TWRP and flash the zip.
TWRP is initialized and fully functional at this stage. Now you can either reboot into system or root, flash custom ROMs via TWRP.
Part 3 - HOW-TO ROOT:
1. Download the flashable zip.
- Option 1: Magisk
- Option 2: SuperSU (untested)
2. Transfer the zip to your phone.
3. Go to "Install" menu of TWRP and flash the zip.
Part 3a - HOW-TO FLASH CUSTOM ROMS:
1. Download the flashable zip.
2. Transfer the zip to your phone.
3. Go to "Install" menu of TWRP and flash the zip.
Simple.

Before the 1st boot i even rooted the device, that remained after the first boot, but no /data mount.
After the 5th try, i gave up.
What could be the problem, or is this normal on this phone?

Are you using latest twrp version 3.2.3.2

I'm using 3.2.1.0

kristof889 said:

Use latest twrp 3.2.3.2 should have data mount and quota issues fixed.
You can flash the .Img file through twrp or flash the .img.tar file with Odin.
After flashing reboot straight into twrp and repeat part 2 of the guide you quoted.
I would be interested to know also if in download mode if you have a line in there saying rmm state?
Twrp for s8 exynos
https://dl.twrp.me/dreamlte/

Installed the 3.2.3.2 version, but nothing has changed. after the first boot into system, TWRP says cant mount /data..
I dont have anything like rmm state in download mode.

I am assuming you followed the instructions that you quoted in your first post.(mainly part 2) after flashing twrp
Did you format data in twrp - not wipe - this is needed to decrypt your phone.
Rebooted back into twrp.
Did you flash the no verity opt zip (version 6) - this will disable re encryption of your phone when booting back into system.
This should all be done before booting back into system otherwise your phone will re encrypt itself.

I formatted data, not just wiped it.
I have installed the no verity opt, the latest version.
Even after these, my phone reencrypted itself.

When do the errors occur ie: during backup,restore,flashing something.
When first starting twrp did you swipe to allow modifications or did you leave it as read only.

You mean, the data mount error?
If yes, immediately after the 2nd boot into TWRP, after the first boot into system. Before i do anything in twrp, i check the log (with the button on the lower right) and it creates a bunch of errors, all in contact with the data partition.
So i can even do a proper backup.
If i flash any zip, upon the next boot into system it says something like verify failed, cannot reboot your phone and it gives a button wich used to restore the phone from recovery, but now i cant even do that bcoz it cant mount /data and thus can restore the phone.

Still sounds like you device is still encrypted.
Doing a factory reset with twrp should work to restore your phone or at worst you can re-flash your firmware.
If you can in twrp FORMAT data again and flash the no verity zip use version 6 zip file
https://build.nethunter.com/android-tools/no-verity-opt-encrypt/
I would be curious to know in twrp in the mount menu what options are ticked as well.

After the fresh flash, it was not encrypted because i could access the internal storage, and data was mounted.
Now in TWRP system(read only), cache and dalvik is mounted, and internal storage says 0MB

What Android version are you on?
When you flashed twrp it should have asked you whether or not to ' swipe to allow modifications ' did you swipe to allow or not.
In the mount menu of twrp I have ticked/checked data,cache,SD card the option at the bottom to allow read only I have ticked - this does not stop me from doing backups but does stop me from restoring (data mount error ) so you can leave it unticked.
I would.like to know your steps for twrp installation (not the one you quoted in first post) as I screwed up when I first tried.

I attached the software information bellow.
I have not swiped to allow for system modifications

First steps were the followimg:
Install .tra with odin
Immediately reboot to twrp
No swipe for system modifications
Format data
Flash no dm verity v6
(Flash magisk)
Reboot to system

Ok basically you have missed a step as far as I can see
(When I did mine I did swipe to allow modifications )
After you have formated data you will need to reboot back into twrp ( use reboot menu in twrp )
Then flash the no verity zip and magisk
If using magisk I would try the latest version 18 it's working ok for me.
Then boot into system to see if everything ok
Then reboot into twrp and see if the data mount issue is fixed.

Thank you for your advice. I will try it in the following days and will post the result.

I fixed this by flashing Renovate ICE's ROM and selecting the TWRP included in the AROMA installer.
Can access storage on TWRP now with no issues.

Why stock???
It pretty much is stock, just you have full control over the apps preinstalled and you can change colours of various UI elements.
It's just easier to flash a zip than it is to flash via ODIN, then flash TWRP and keep trying over and over to get this result when I know this rom works fine with CTSprofile.
You will only need to flash TWRP once and copy the rom to your phone.
The rest is magic (AROMA)
I haven't really had to mess with anything and have just installed and used the HSBC banking app as if it were an official phone. (ROOTED and custom ROM and Recovery)
One extra step you could take is to use Magisk hide and point it to the app you want to hide root from.

Need some help - Strange OP6T storage issues after flash

Hello, I have a T-Mobile 6T which thanks to the XDA thread about bypassing T-mobile, is running the international firmware so I didn't have to kiss their butt trying to unlock the bootloader. Yesterday I decided to try the Resurrection Remix rom since it is unclear whether the Lineage 16 rom supports the in-display fingerprint reader, and I am too busy at work and too lazy to read the entire thread to see if it does.
I followed the instructions and updated my OxyOS to the latest .15 release via TWRP which I also updated to the latest version via OTG using a USB drive because I was unable to unencrypt using the older Blu-Spark TWRP version I had installed. After the OxyOS update (on both partitions) I flashed TWRP again, rebooted to recovery and installed Pico Gapps.
I found the Resurrection Remix rom to be very buggy and I hate the way the in-display biometric works (very slow and I don't like the paw print used as fingerprint placement). Anyway I started installing apps and after 4 apps installed, it says there is no space left in storage.
Nothing will update, and when I try to check storage with any file explorer it says "access denied" or just won't load. I've tried everything. Wiped the data and did factory reset, then flashed stock rom again and same issue. What am I doing wrong?

That looks like a messed up flash. And is pretty common. Considering that A/B is still new and everyone has his own method of flashing. So assuming you can make it back to latest Stock OOS (9.0.15 right now). If you dunno how to then simple reboot to recovery, flash OOS ZIP and then TWRP. Again Reboot to Recovery from within TWRP (Reboot -> Recovery) and again flash OOS ZIP and TWRP Installer. For TWRP I recommend you to grab the latest one (3.3.1-6 as of now). Once flashed, Format Data (Wipe -> Format Data -> YES) and Reboot. Wait for it to boot up. Now you should be on Stable Stock OOS with TWRP Installed.
Now Download ROM of your Choice (RR, LOS, Bootleggers, whatever). You will also need the latest TWRP Installer (same as above) and Gapps (Nano/ Stock Recommended) and Magisk if you want to Root. Reboot to Recovery, flash ROM ZIP and TWRP Installer ZIP. Wait for it to Finish. Reboot to Recovery. Once in TWRP, again flash ROM and TWRP Installer. Once done, again. Reboot to Recovery from Within TWRP. (Read above on how to). Now, flash Gapps. Magisk if you want to Root. Once done, again do a Format Data. Reboot and be patient for ROM to boot. And then tell me wether this works or Not. Good Luck.

Flash custom ROM

From 6T (purchased from oneplus.com), any time I follow the instructions for how to flash one of the custom ROMs, I get stuck at the bootloader with no working rom.
I was able to use the MSMTool to restore to 9.0.13. I upgraded a few times flashing OnePlus6TOxygen_34_OTA_024_all_1909112343_9fd6e0057b8747dc, which works, but when I try to flash a custom ROM, I cannot get past the bootloader. I say a few times because I've tried this for a few days now with no success.
Most recently, I used the Flash-all.bat inside 10.3.0-OnePlus6TOxygen_34_OTA_042_all_1912142031_d9ef3-FASTBOOT
I am currently on 10.3.0, with twrp-3.3.1-31-fajita-Q-mauronofrio installed using the fastboot flash boot_a twrp-3.3.1-31-fajita-Q-mauronofrio.img then fastboot boottwrp-3.3.1-31-fajita-Q-mauronofrio.img commands from fastboot.
I can then install Magisk 19.4 or 20.3, however again when I try to flash a custom ROM, I cannot get past the bootloader.
What am I doing wrong?

When you 'fastboot boot' twrp, you can't flash twrp as .img file after that..... (There is no recovery partition on our phone, only a boot one)
If you flash a twrp img it will overwrite boot partition with only twrp and no kernel... Basic knowledge. Once temporarily booted in twrp by 'fastboot boot' command you must flash the installer, meaning the .zip file.
Then reboot your phone in twrp and flash whatever you want
Always latest versions of Magisk, why flashing a deprecated 19.4?

I was having an issue with the boot command in 10.3.0, which is how I found the flash command, and using both of those seemed to work (at least get me into twrp).
Now I am able to just run fastboot boot twrp-3.3.1-31-fajita-Q-mauronofrio.img and it works.
I was using 19.4 because somewhere in here someone mention twrp not working with magisk 20.3.
I've had no issues with 20.3 and twrp, so I will continue to use 20.3
The steps I use to flash a custom ROM (after twrp is installed)
1. remove the lock screen security from the existing ROM
2. boot straight into recovery from the existing ROM
3. wipe Data, Cache, and Dalvik by swiping right to factory reset from the wipe menu
4. flash the ROM from internal storage using the Install button
at this point I've tried a couple of approaches including a reboot here to see if the ROM flashed, and also installing twrp right after flashing ROM so that I will have a working twrp install.
Either way, I can never get past the bootloader.
Am I performing these steps correctly?

I don't know I don't flash custom ROMs anymore, too old for that stuff and need my time for me.
There are specific instructions for each custom ROM it's better to ask in dedicated threads, some of them need to have OOS in both slots before, some of them need to be fleshed in both slots. Normally you eventually wipe things, flash the ROM and twrp to keep it, then reboot to twrp (necessary to boot on the slot where the ROM is actually fleshed, which is always the non active slot, which become the new active slot) and flash Gapps and Magisk ( because Gapps and Magisk can be flashed only in active slot) then reboot system

I've updated these instructions here, they are the same, just added to them really.
This is how I install Lineage 17. (If you are doing 16, replace 10.3.0 with 9.0.17, and the Q image of TWRP with the Pie image)
- Install 10.3.0 fastboot ROM again to start over, boot it once. Just to make sure everything is good.
- Reboot to fastboot.
- Boot the Q image of TWRP.
- Run the TWRP installer, reboot to recovery
- You backed everything up right?
- Factory reset (This is the slider at the bottom in the wipe menu).
- Format data. (This is the button that says Format data in the wipe menu)
- Do NOT wipe cache, do not Wipe system, do NOT Wipe Dalvik / ART, do not add anything else, Just Factory Reset and Format Data. After doing those two Reboot to Recovery one more time. You must do this after formatting data.
- Now transfer Lineage and TWRP to your phone, Windows / Linux should see TWRP fine as a media device when plugged in.
- Install Lineage
- Run the TWRP Installer.
- Reboot to Recovery.
- Install Lineage (You need Lineage on both slots, so yes run it again)
- Run the TWRP Installer (yes again).
- Reboot to Recovery.
- Install Gapps if you want them.
- Install Magisk 20.3 if you use Magisk. I used 20.3 it works fine. (20.4 also fine) Do not install modules or other add ons at this point. Boot once and go through the setup and everything, then install your add-ons.
- Be aware the phone will restart once, then Lineage will start up and all will be good.
From that point on updating should just be like normal :
- Reboot to recovery
- Flash Lineage.
- Flash TWRP Installer
- Reboot to Recovery
- Flash Gapps. (Assuming you use them, if you installed them once you must continue to install them or do a clean install)
- Flash Magisk. (If you use it)
- Reboot to system.
- No loss of data, or anything.
- No need to flash anything twice etc.
I've posted similar instructions here. It was just for LOS 16, same thing essentially though.

Sir, apology for being an old noob, I am on OOS 10.3.2 TWRP 3.3.1-32 can I follow the above guide? If Yes,
Why aren't we using the "Lineage Recovery" provided in "Lineage OS Downloads" page?? If we use it, will the above instructions change ? What are the cons of using it?
Sorry again for asking!! Can you please share me the Link to Open Gapps which Will be suitable in my scenario ?

Historically Lineage / CM recovery was hit or miss, or TWRP or other recoverys worked better. To be fair I haven't even tried the Lineage recovery. So maybe that is no longer true? Right now, I know TWRP works. The updated instructions link up there has links in it, FYI, link OpenGapps. OpenGapps can be found here. You will be using Arm64, Android 10 obviously.
Since you are already on 10.3.2 (I assume you were on 10.3.1 before) you should be good to skip the step about fastboot ROM or install OOS, and you already have TWRP., so you should be able to go right on to backing everything up, wiping everything, and installing Lineage. (So you can skip the first few steps)
Anymore questions feel free to ask.

First of all, thank you very much for your time and explanation.
Sir, so i will proceed as follows:
* Boot into TWRP Recovery
* Perform "swipe to factory reset" & "swipe to wipe data"
* Reboot to TWRP recovery again
* Flash LOS 17.1 on slot A
* Reboot to TWRP recovery again
* Flash LOS 17.1 on slot B
* Reboot to system
Sir, please check are my steps correct? If not,
From which step( steps mentioned in your guide) should i start?
Last query is, which GApps zip will be best for me, micro/nano/pico/tv stock, If i want max coverage of google?
Very sorry for knocking you repeatedly!!!

Your starting point is correct. However make sure you don't miss the re-install TWRP after flashing Lineage each time, and the second time you need to flash Gapps before you reboot to system.
Personally I always do Nano. Anything else you need (that would be included in Micro) can be installed from the Play store. Nano at least includes all the things that can't be installed from the play store.
Pico has the least in it. TV is for TV devices. On OpenGapps there is a box next to each package you can click and it will tell you exactly what is in each package.

Sorry for the necropost, but this also works for TWRP 3.6 and Lineage 18.1. I initially had a problem with the default TWRP for my 6t. During the initial TWRP fastboot the version on their site caused a firmware error which I could just barely get out of, but it screwed up the system boot process in some subtle way that even the fixed version of TWRP (found on this site) couldn't solve.
After trying your instructions above, it didn't work the first time because of the screwed up system boot. It just kept trying to boot to recovery. I suspected a firmware error and was almost going to do an mcmdownload soft-brick rescue. I tried one last thing, using the TWRP on the system to sideload the stock ROM. That worked and patched up the system boot process. Once I booted and ran through some basic initialization to make sure developer options were properly set I followed the above instructions and it worked nearly flawlessly.
One strange thing. After I installed Lineage 18.1 and TWRP to both partitions (as well as Gapps / magisk), it rebooted to system and almost booted without incident -- except a large circular logo popped up that said 100% and stopped. I figured that that meant someting completed properly, so I powered off, waited 10 seconds, powered on and then the Lineage green system initialization spinner came up for a few minutes and it went through the user initialization sequence.
Thanks. I almost gave up and bought a new phone.

OhioYJ, these are great instructions but it initially left me with questions about how that procedures would create duplicate installs on slot A and B. The answer is of course that the Lineage installer for the 6t knows about the dual slot setup and always writes to the inactive slot. Booting into recovery activates the inactive slot so that installing again after that installs to the other slot and now you have Lineage on both slots. The installer for TWRP always installs to both slots and is needed because Lineage always installs its recovery handler and you don't want that so you overwrite.
PS: TWRP has an option for installing itself after installing the requested package. Would that be just as good as installing the TWRP zip?
PPS: I had to do an 'adb push' of the Lineage and TWRP zips to sdcard for the installs. Unfortunately installing and slot switching makes the sdcard unavailable so you have to push the zips again. Is there somewhere I can write them to that I don't lose access to after a boot to recovery?
