[LG V30 ROMs, Kernels, Recoveries, & Other Developm] seadersn:
Hi!

!!! First things first: big phat huge !!!THANKS!!! to the full TeamWin Team, SGCMarkus (initial twrp tree), Phoenix591 (for inspiration), Dees Troy (for his trees), z31s1g for his brilliant theme and Captain Throwback (inspiration, too) !!!

For Pie ROMs you should use 3.3.1 recovery, either OrangeFox (based on TWRP with many very useful additions, with Magisk module manager being only one of it :good: ), or good old TWRP itself. 3.3.1 needed for decryption of pie ROMs!
​

Feature list:

- capable of installing treble and/or vendorized ROMs

- Possibility to leave out lockscreen settings when restoring a backup (sometimes you have to delete them manually, otherwise no login into your restored ROM possible -.- You can bypass this with this. Note: lockscreensettings are independent from your encryption settings)

- Time and date is showed correctly, independent of /data

- some extra partitions (see below)

- Oreo 3.2.3-7: compiled with (modified) 8.1 TWRP branch

- Oreo recovery: Decryption of AOSP up to 8.1 and stock ROMs userdata is working (cherrypicked stuff for bringing that up), so, with this recovery, the urgent need for flashing no-verity-opt-encrypt zip isn't there anymore :)

Pie is not decryptable for the moment, neither with old Oreo recovery nor with newer PIe recovery: this is being worked on. Encryption changed in Pie, this needs some extra "love"

- everything working: backup, restore, decryption, time, mtp, adb, installing of treble or vendorized builds, themeable, .........

- modem image support: backup, restore, flashing of modem images either taken directly from kdz or via diskdump (this already was available but then broken at some point of time, sry for that! ;)).

- Same for OP image

Don't forget your timezone settings after flashing. Also there are some extra partitions you can mount/backup/flash/explore, like LAF, persist-LG and OP configs. There's the thought of some people to flash TWRP as a second copy to LAF partition to be on the sure side when it comes to ROM switching or sth like that. You can do this, anyway it's not really recommended (by me and some others) because you'll lose download mode, but you now have the option.

Also, if you want to restore an older backup, don't restore 'firmware' from it!!! This will break your WLAN, at least, and you have to flash a modem.img to get it back working.

For extra partitions: Some of them are needed for decryption (modem / persist-lg (drm)), some are for VoLTE (OP), time is stored on /persist/time (and /data/vendor/time), modem should be known and the LAF partition should be known already (described above).

For decryption: it works as it should. Therefore it is a little bit tricky to restore a ROM which has encrypted userdata, when you'd installed any other ROM in between. or formatted data There are some points to remember when restoring, a little guide is available in 3rd post, and some tipps too.

Some instructions:

How to flash?

If starting fresh with an unmodified phone, this thread should help you installing it

When you already have TWRP installed, you can flash this recovery from within TWRP:

- Tap "Install"

- Tap "Install image" button, located down right

- Locate your downloaded image and select it

- Select "recovery" from the list which shows up then

- Install; and reboot to recovery after installing immediately, don't use it for any other tasks until rebooted pls, as it may not function. Things can go bollox when phone wasn't rebooted to recovery after installing.

And of course you can flash it via fastbootmode. Reboot to bootloader (adb reboot bootloader;

when magisk is installed, you can use magisk manager => module => menu on the top right => reboot to bootloader. You can reboot to recovery from there too

) and then:

fastboot flash recovery <twrp-image-name.img>

When you experience errors or sth isn't working as it should in your opinion:

When an error occurs, pls supply me a log from TWRP, taken immediately after the error showed up. You can use the "Copy to SDCard" option (advanced options) in TWRP for this. Grab this file then and upload its content to pastebin.org.

I can't help without as much detailed info as you can supply. This should include at least following information: phone model, used TWRP image (exact name of image), task you wanted to do (which ROM e.g.).

There's now an optional version of TWRP available, which contains the inclusion of internal storage in data backups (IntSD version). Exclusions (folders which won't be backed up): TWRP, Movies, Music and Download folders. These won't be included in backups, as they can be really big.

With the recovery including internal storage you can backup to internal and external storage, no matter. The data_image recovery can backup its data image to external sd only, of course.

If you want to use data_image, system_image or internal storage included in data backup, first check your filesystem on your external sdcard. It needs to be capable of writing big files, which isn't the case with fat/fat16/fat32. You need exFAT (for stock) or ext4/ntfs (only available with custom kernel and/or AOSP based builds).

Some additional words to different versions;

I personally use internal w/ sdcard backup, all my pics and almost everything possible app related on my phone is on external SDcard. Some data always remains on intSD (e.g. whatsapp, the Android folder which contains settings and app data too, k-9 mail folder and others), this needs to be in a backup for me. This is, what the intSD version does: but it leaves out the big folders (download, music, movie and TWRP).

As always: Use it at your own risk! You are the one who changes stuff on your phone, I'm not responsible for anything which happens to your phone. TWRP is powerful, be careful at what you do with it :good: And it just works.

All you need to compile this yourself:
