But is it really oreo? The old version of TWRP-3.2.3-1 works fine. What changed since then?

Ahh okay sorry. U are not talking about lineageos ;)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Phoenix591:
that would be news to me if 3.2.3-1 works with stock lg oreo encryption, I've tried switching back to previous ways encryption was handled a few times without success.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xSOADxMANx:
downgrading to 3.2.3-1 worked for me when I accidentally triggered encryption on my VS995 running AO oreo. After that i was unable to flash any zip until i upgraded twrp back up to 3.3.1.

Don't ask my how or why, just reported my experience :)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Phoenix591:
Just released 3.3.1-1. I changed the very last thing I could to make it behave the same encryption wise as the old version that people have had success with.

I havn't tested stock based encryption, but it certainly decrypts lineage 16.0 just fine.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ozkaya:
I am on stock Oreo and want to put engineering aboot and TWRP on my device. Is it possible that I can disable encryption first so that I don't have to format data after installing TWRP? If no, would it help my device has already root thanks to the new exploit, just not engineering aboot and TWRP?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Phoenix591:
Sorry, it isn't. Forced encryption is set in the boot partition which (like system) checked for modification by a locked (non-engineering) bootloader. (And if it detects tampering it won't boot)

Technically data is decrypted between the time someone does a factory reset and the system boots stock recovery to wipe data and the next boot, but that doesn't really help.

Flash the img file (choose install image) in TWRP making sure to overwrite the recovery partition.

Lineage 17.1 roms will not restore

H918: latest Lineage 17.1

Using TWRP 3.3.1-1, I backup-ed this Rom a couple of times. Seemed to work. However, when I needed to restore one of these backups, it did restore it, but the Rom would not boot afterwards. It booted to the Lineage whoosh indicator screen but no further. I waited 45 minutes and it did not boot. I then tried with another backup-ed 17.1 Rom with similar results.

I had no problem booting a restored Lineage 16 Rom.

Has anyone on Lineage 17.1 seen something similar, or found a way to fix this?

Thanks.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] scottyrick:
I probably should have just wiped the system partition, reinstalled lineage 17.1 and gapps and rebooted. Did not think of it at the time.

Hi there, i'm posting here cause my device (REDMI 3S) TWRP (Official, from website) has a wrong clock and i can't find out why! It's not the typical 1970 issue that's fixed with reboot, no : no matter what i do, date's OFF for one year and a half or so, and clock off as well! Using some custom versions of TWRP, clock's ok but these versions have other worse issues such as no decryption support, so can't use. Hope OP will explain me why & how this can be happening and how to fix it, thanks!

PS: When typing "date" in terminal, i get this :

__bionic_open_tzdata: couldn't find any tzdata when looking for WST -4:30WDT

__bionic_open_tzdata: couldn't find any tzdata when looking for posixrules

Download mirrors seem to have gone away for the US996 version....!

Can't get 3.3.1-0 to "stick" - it flashes OK, apparently, but isn't there when I try to boot into recovery.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] SimpletonSimon:
Can I use this to flash a Nougat ROM (SuperV20 specifically)? I'm on a US996 and have been using TWRP 3.2.3 for a couple years but it never was able to properly handle the partitions /vendor /vendor-img and /usb-otg

Also, it is as easy as re-flashing the zip of my current TWRP version if it has issues and I need to downgrade?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Vortell:
It should work not sure if super comes with full firmware though. Not sure what you mean by it doesn't handle partions right. Never had any issues with flashing, backing up or restoring any ROM. I also never had any issues with using otg with it or ROMs flashed with it. I use ao Oreo on one us996 and lineage 17.1 on a h915 cross flashed to us996. Also you you can normally downgrade using twrp to flash an older version twrp. I have not personally tried this for this version/phone.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] SimpletonSimon:
Looking at the zip, SuperV20 seems to include firmware. According to my logs, TWRP 3.2.3-0 never in the last two years mounted/unmounted the partitions I listed (and when I boot to recovery I'm unable to mount /vendor). I don't know what OTG is so can't confirm if it's working despite my TWRP logs indicating it can't mount it.

I'm ultimately trying to confirm that TWRP 3.3 will work with Nougat... I've read elsewhere that it's exclusively for Pie.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Vortell:
It can't mount it unless you have usb c drive connected to it. Either way it was updated for it but still works with nougat.

Hey guys, just coming back to my v20 after a year lol

Currently on the lastest firmware I believe (20p or something)

I was on lineage 16 last year, then went back to stock for a friend to borrow.

I am bootloader unlocked already.

Adb works and is recognized

Fastboot shows device and responds to commands

While trying to flash this recovery in fastboot, I get the error (FAILED (remote: 'unknown command') on the writing step. I will attach a picture of the error. I even tried booting straight into twrp using the boot command and same error.

Do I need to downgrade with the old lg flash tool?

Wipe something again? Relock and unlock bootloader? Is it an issue with my adb/fastboot environment?

Any advice would be appreciated. I googled my issue and got a ton of random answers but nothing recent.

Thank you!

Misread.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Phoenix591:
H918 can't use fastboot flash, no V20 can use fastboot boot. If you went totally 100% back to stock (ie if you don't have any twrp installed) you need to downgrade to 10p and use an exploit. Guide, reworded version of the guide (more detailed iirc).

Decrypt

[MENTION=8639605]Phoenix591[/MENTION]

Maybe you can take a look at the data decrypt routine under LOS 17.1 again please? Which works fine under LOS16, fails now under LOS17.1

Data isnt decryptable in TWRP. Guess TWRP 3.4 was an autobuild, as it also doesnt decrypt LOS16 anymore, but the 3.3x builds here do.

Thanks.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Phoenix591:
What's ended up on the official twrp website is a very old version, even older than the last one here on this thread. I gave them that version, then ran into several issues, and decided it would be easier to work on those issues by doing it on my own machine. Months later they released that version without contacting me. Their 3.4.x version is based of that ancient buggy version.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] aCIDsLAM:
Ok, thanks for clarifying this.

Maybe you find some time to get your version working with LOS 17.1. Thanks for your work so far!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Ms0206:
That definately would be awesome...I run into the same issues with decryption ("unable to mount storage" and "decrypt took too long") and looking forward for an update (using Los 17.1).
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
Seems to work fine here.

Only ever used the official TWRP builds and things worked.

Additionally, for unofficial builds, you'll need to include https://gerrit.twrp.me/c/android_device_lge_rs988/+/2696 - or else OTA won't work on Lineage - hence the reason I had 3.4.0-1 builds for all G5/V20/G6's fired off.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Ms0206:
Have you turned LOS' encryption on?

I am on official 3.4.0 now - and it does not work here. Enter my password in Twrp does not work and the update is producing several Magisk- and mounting-errors. After the last update Magisk was gone and I had to reinstall several things...
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
I don't encrypt beyond testing.

I reccomend Lineage Recovery for use with LineageOS. Even our wiki does so.

However, I test OTA's and flashing unencrypted with TWRP for those that really want to use it. Both of those work.

Decryption in recovery is a and concept IMO, hard to maintain, and likely to mess stuff up.

I don't support it. Someone else can fix it if they want.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Ms0206:
Not very satisfying to read such statement from the maintainer(s).

However, 3.4.0.1 also does not work, same Problem - "cant decrypt, unable to Mount ...".

OK so we have to switch as Twrp is missing a very important functionality atm and in near future - can someone tell me if I can switch to LOS' recovery without problems now? Has it the same functionality, any regressions? I never have tried that, does it also work with my actually installed things like Magisk?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] scottyrick:
I believe you will discover that there are no recoveries that decrypt for our devices. LOS recovery doesn't even backup your phone. I believe that without decryption there is no NAND backup. Encryption is a feature that most of us have never needed and never have used. Good luck and let us know if you are successful in finding a better recovery.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
Again, I can't really state enough that decryption in recovery is not a designed intention per Android standards, and in my eyes is a totally optional feature anyway. like I said, if someone wants to fix it they can.

we fully recommend lineage recovery, it doesn't mount data at all if it's encrypted, but OTA will still work nonetheless, And yes, we work regularly with the magisk and open gapps maintainers to ensure compatibility with lineage recovery.

yeah, at this point Android isn't really designed to be backed up from recovery - - just do it from user space using Google backup, or if you're super aversed to Google backup, seed is a fantastic alternative that Lineage is going to be integrating fairly soon
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Ms0206:
I see...now I am on Los-recovery...and its useless (edit: as far as I can see...it 1. does not install the ota-update automatically as Twrp did and 2. it seems it does not work with Magisk...possibly I have to read and try a bit more)

I think its not necessary to discuss the importance of encryption here.

So this is a very, very frustrating situation now! I hope the two maintainers here will be able to sort out their (version-)conflicts and someone provide a working update soon, this unfortunately exceeds my knowledge and I cannot help much.

It would be great if Twrp will not be left in this state for this device.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] mangokm40:
npjohnson,

First, thanks so much for making this available to us. Please disregard the whining.

Second, I am "super aversed". :) Is the "seed" you referenced above "SeedVault" from Calyx Institute? Is this something we should look into

now? Should we wait because it will be "integrating fairly soon"?

Thanks again for your time.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
Yes, it's seed vault, you can use it on your own, but if you want to wait, it should be rolled in in the next month or so I'd estimate.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Ms0206:
Joker...this situation is like a car - yes its good - but without the key to unlock its locked doors.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Ms0206:
After trying around some hours I can say that using Twrp 3.4.0.0 is still the best option. Lineage its recovery does not even install anything automatically nor does it ask for any pw at all - it looks as if there is no decryption at all.

Not sure why its mentioned here to use that...just wasted my time.

And following official wiki-guides also does not work, everything producing the same errors as Twrp (Magisk addond.d failed, cannot find Magisk binaries, reflash OTA Form decrypted recovery or reflash Magisk).

Btw, 3.4.0.1 does not even start the OTA update automatically here...I have to verify but it looks as if older 3.4.0.0 worked better/as it should (except decryption).

But no method I tried can handle updates with installed Magisk and encryption turned on.

TWRP decrypt workaround LOS 17.1

Hello,

thought this may help other people. I found a workaround, for the problem that decrypting stops working, when using LOS 17.1, while it works when using LOS 16,

preventing me from updating the OS, as i cant backup DATA anymore.

I simply flashed a LOS 16 over LOS 17.1 and rebooted. The system wont boot up completly anymore but you are able to reboot into recovery and decrypt DATA in TWRP,

allowing you to do a backup. When you are done, you can dirty flash LOS 17.1 again and everything seems fine.

While this is not helpfull, for the everyday backup, with this method, i would be able to swap my devices and taking my DATA with me, when i am on LOS 17.1, which is important for me.

Wouldnt that rather speak for, something is missing in the ROM, rather than in TWRP?

Video isn't working but I assume the answer is to turn power on and off once fully booted. That's because it's not the "stock" kernel it's the debug one. Oh and this definitely had nothing to do with twrp. This should be in the rooting thread or what ever rom you're using. Oh this had been answered 100s if times on the lg v20. I suggest you try a search for lines or static on what ever thread you rooted from.

Which version of TWRP should I use, seems like the newest version is 3.5.0 and it does seem to run on my Mobile F800K... Any biggie over using this from 996?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ssurell:
I think 3.2.3-1 is the last good version. The only one that worked right for me anyway. Apparently our TWRP recovery is being robo-updated based on a buggy version.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Jesus is God Almighty:
Yea seems I got some issues installing 3.5.0 :/ The system went total slow... although there are so many factors and still toying around with things. Having some hard issues getting it to do what I wanna have it do. Takes ages to get things to do what one wants because of all the insanity of Google. What should have taken me a second to do is taking ages... Because of criminals who love putting people in jail and control whatever they wanna do with there bought hardware.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Jesus is God Almighty:
This TWRP version gave me issues and problems... So had to go back to 3.0.2-1-us996 I think it was to get things working. Dunno why, as this was refered to, although in an older version.

But overall the older version seem to do it for me.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Jesus is God Almighty:
Have no idea what robo-updated is, based on a buggy version overall means. But at least I had issues with the recovery-twrp-f800-2019-10-25_3.3.1.1 unofficial and had to go back to 3.0.2-1. I have not tested 3.2.3-1, you mean the official us996 or the unofficial?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Jesus is God Almighty:
3.5.0 us996 did seem to make the system overall, very slow... I have to further test it or just keep with a older version, not a biggie overall really... As long as my mobile works ;)

Have lots of things to further test.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Jesus is God Almighty:
I'm using AnTuTu, seemed a lot of people are using it. So I think I will use that to test things out, have a couple of Kernels to test out and go from there I think.

Should test this Rom vs the mk2000, and have one more kernel although I don't think it will work. But I think this or the mk2000 will be a pretty good choice overall, at least it seems pretty stable for me, the one I'm running now. But if I can get some more juice out of the phone as well, it would not be bad.
