as far as i encountered twrp cannot decrypt partitions on v30 even if i enter the CORRECT password or pattern.

i just disable decryption from the start to not have any headaches later :)
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] hammad506:
How do i do that though. Flash no-verity-opt-encrypt-6.0.zip on stock 10f? Or is there a more sensible risk free way?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Pisolo:
Fortunately I had already disassembled earlier to replace the display and now I'm waiting for the new cover battery and the adhesive to request it.

It went well.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] iRS_:
you can force reboot the device by holding volume down and power button :)

---------- Post added at 06:52 AM ---------- Previous post was at 06:50 AM ----------

first you need to FORMAT data partition, not just WIPE it then flash no-verity-opt-encrypt-6.0.zip.

I got the stock 20 EU Oreo downloaded, it would be great if someone would guide me step by step to get from 10f Nougat to rooted twrped Oreo.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] iRS_:
if you are fast enough you can enter bootloader mode by holding power and vol down and when the screen goes off, hold vol down and insert usb cable STOPPING the phone from bootlooping and enter in bootloader :)

i do this when i am too lazy to enter in rom to power it off.

what help do you need?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] hammad506:
From SGC Marcus debloated ROM instructions

"(FLASH INSTRUCTIONS

Make sure your /data isnt encrypted though. I dont know how it will react if the ROM finds an encrypted /data partition, as I disabled it alltogether (****ed it up for me, even though forcencryption was off)

1. Download ROM + (potential) hotfix

2. Copy it on your sdcard/internal memory

3. Boot into TWRP

4. Make a Backup of Boot/System/Data/Cache

5. Wipe /system, /data, /cache, /dalvik/cache in TWRP

6. Flash .zip file(s))"

At what point do i flash rtcd disabler and encryption disabler zips..

I'm planning to be safe and flash Stock Oreo using LGUP and doing the TWRP root afterwards doing Magisk

[emoji53] I'm kind of confused here.

I've already been bitten by encryption and failed TWRP backup once.

Scrap that. Uppercut with stock 20d is not working for anyone. (Ref. Stock 20d Oreo thread)

---------- Post added at 10:23 AM ---------- Previous post was at 10:19 AM ----------

I just need a way to update to Oreo without burning the ships(backing up/ disabling encryption) i guess ill go the debloated oreo way, or maybe wait a little more to get a more stable iteration.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] iRS_:
i suggest you to flash a KDZ file using LG UP, assuming that you have H930 version (i do not know on what other v30 variants works)

LG UP + Uppercut

the firmware itself

twrp for oreo

magisk 16

encryption disabler

root checker disabler

flash oreo H93020d_00_OPEN_EU_OP_0326.kdz using LG UP and make sure that you checked REFURBISH

put phone in bootloader mode

flash twrp fastboot flash TWRP-3.2.1-joan-v0.1.img

boot twrp fastboot boot TWRP-3.2.1-joan-v0.1.img

swipe to allow modifications

select WIPE, then FORMAT DATA, then write yes

wipe cache, dalvik, data

flash magisk

flash encyprion disabler

flash root disabler

reboot
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] hammad506:
Over at the stock Oreo thread (ref autoprime's post) it says flashing Oreo closes some downgrading doors.

Would performing the above steps on my 10f Nougat get me root? And what about when it auto upgrades from 10f to 10v..11 firmware. Would i be loosing root then?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Pisolo:
What difference between REFURBISH and UPGRADE ... ??

From the most negative experiences I had to overwrite OREO with LGUP.

I did not succeed with Uppercut, only the first time to move from Nougat to Oreo.

I had to create the "common" folder in LGUP, copy the common.dll DLL Version 1.0.31.9. Abandon Uppercut and launch LGUP.exe.

Only after this opraction I installed OREO with UPGRADE several times.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] iRS_:
i didn't try to downgrade using KDZ but u can always downgrade using ZIP format roms, but why would you downgrade from oreo to nougat?

if u use the firmware i linked to you will have 20d, NOT 10f, 10v or 11, or whatever...

so what if you lose root?

you just flash magisk again :)

---------- Post added at 01:25 PM ---------- Previous post was at 01:21 PM ----------

refurbish erases the entire phone, while upgrade does not. i STRONGLY recommend to use REFURBISH, always !

i am not a fan of dirty flashes... (i know that you might be lazy but it could save alot of time if you ever encounter problems after a dirty flash)

you should always do backups, erase, restore (titanium backup is the 2nd best purchase i did)

i am not ussing uppercut too, i am using the common dll, not even the oreo one :)
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Jerry08:
I downgraded to Nougat from Oreo without any problem using kdz.

I ask if with this TWRP someone has done a Backup of the Rom and subsequent Restore.

Everything works ... ???
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
Backing up and restoring nearly daily because im testing los ... works all the time ^^

Tested, at the end of Backup I read on TWRP: Backup Failed. Cleaning Backup Folder.

In the TWRP folder of the external SD I see the Backup.

Do I need to worry...???
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
O.o

Send me the recovery.log (/tmp/recovery.log)

Which app you advise me to go to retrieve the requested log.

The old Root Explorer does not open.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
you pull it in TWRP after you got the error

either with adb (adb pull /tmp/recovery.log), or i think TWRP has a button to copy the log too, or you use the inbuilt file explorer of twrp

[MENTION=3475147]SGCMarkus[/MENTION]

Ciao.

I hope it is the recovery.log that my requested.

Made with TWRP immediately after launching the BACKUP.

Tell me if that's what you were looking for.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
Checked the log, its failing at creating a backup of "system image", is your sdcard formatted in fat32 by chance? doesnt allow files bigger than 4GB, which the system image would be.

Otherwise, just backup boot, recovery, system (not system image), data and cache

thats what i always do
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Pisolo:
[MENTION=3475147]SGCMarkus[/MENTION]

I confirm FAT 32, I have to format in NTFS ... ???

I always do Full Backup.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
system image is only needed when you wanna flash it via fastboot what i know

a backup of system (not image) can be restored via twrp too and contains everything (just is smaller)

Also im using exfat for my sdcard, even though also proprietary filesystem like ntfs, but still... like it more lol

less problems with linux usually (for me)
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Pisolo:
[MENTION=3475147]SGCMarkus[/MENTION]

Which of these items should I select to do a full backup with external SD in Fat 32 ... ???

* Boot (40MB)

* Recovery (40MB)

* System (4606MB)

* System Image (6394MB)

* Data (excl. storage) (3191MB)

* Cache (1MB)

* EFS (6MB)

Thank you.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
Im always going with Boot, Recovery, System, Data and Cache

I have an older backup (also saved to my PC) for the EFS, just in case... but that partition shouldnt ever be touched anyway.

I reverted from 11m to 10f firmware to get TWRP to stick. Now I've got a rooted TWRP'd 10f Nougat. The OTA to 11m showed up a while ago and downloaded (~468MB). When i choose install it unmount sdcard, reboots to TWRP.. When i reboot back to system it get me back to my old 10f.

Not that I'm unhappy with my 10f and root.

Jussayin it wouldn't update anymore. And i did try going from 10f straight to Oreo. Got a nay on refurbish.

Will wait for a stable Aroma Oreo to flash.

yes, if you wanna install a recovery :)

or to boot for a boot.img

So I flashed the recovery image in twrp 3.1.1 to the recovery partition. Got a successful flash dialogue. I'm confused at this point as the twrp version still says 3.1.1? Is that what it should read? Do I need to flash through fastboot recovery instead?

Thanks in advance.

Forgot to say, I'm still on 7.1.2.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] HarryCustom:
Hi just unlocked and flashed TWRP, but I can't access recovery.

"Adb reboot recovery" takes me to a dark screen with the robot image and "no command".

I've tried this procedure:

1. Hold both volume down and power until you see the first logo

2. Let go of power while still holding volume down

3. Press and hold down power again, along with volume down

4. You will be on a white screen

5. Choose yes and yes, you have to do this erase procedure twice

6. After the second erase you should now see the twrp splash screen

But every time the phone asks me to erase everything.

So how can I access to recovery?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
Did you reboot into recovery again afterwards?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Ballroomblitz:
I flashed the image, rebooted system when I got message that image had flashed successfully. Rebooted to recovery and looked at version number at the top of the twrp screen.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
Weird... try to instantly reboot into recovery again after flashing the new TWRP image inside TWRP. TWRP offers you a Reboot to recovery in the reboot menu (just press back once or twice after flashing and go there then)

Otherwise... flash via fastboot :/
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Ballroomblitz:
So I reflashed the recovery image. Backed out and rebooted to recovery, and it still says I'm on 3.1.1. I guess I'll have to try to flash using fastboot when I get home.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Ballroomblitz:

Unlock bootloader using LG guide

fastboot flash recovery recovery.img

Boot TWRP (Allow system modifications)

Flash Magisk 16

Enable MagiskHide

Celebrate safetneypass.

Will I lose certain functions by unlocking bootloader?

Recovery 3.2.1 soon you can use it without the command "fastboot boot TWRP-3.2.1-joan-v0.1.img" ... ???

Another question, news on the net about how to re-lock the V30 H930 ... ???

Thank you.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
after you flashed it with "fastboot flash recovery TWRP-3.2.1-joan-v0.1.img" you can also boot to it with the button dance.

"fastboot boot TWRP-3.2.1-joan-v0.1.img" is just there so you can get into recovery easier the first time, to allow system modifications so the stock system wont override it again.

And nothing known to me about relocking the h930
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] foamerman:
Hey guys this is just a suggestion instead of doing the button dance you should install reboot manager from the play store we already have root it's a lot easier I've used it for a long time on a lot of different rooted phones

Sorry [MENTION=3475147]SGCMarkus[/MENTION], my fault if the Reboot Recovery did not work.

When the "No command" appeared, it was due to the fact that the your Recovery TWRP was not installed.

Guide to installing the TWRP Recovery on LG V30 (H930)

Driver LGMobileDriver_WHQL_Ver_4.2.0.exe

Prerequisites:

• Enable "USB debugging" from the Settings / System / Developer Options.

1. Download TWRP Recovery for LG V30: https://xdaforums.com/lg-v30/development/unofficial-twrp-3-2-1-t3779171

2. Copy the downloaded recovery image file to the C: \ adb folder where all the ADB and Fastboot files are present: https://androidfilehost.com/?fid=24686681827312411

3. Within this folder, hold down the SHIFT key and right-click on an empty space.

4. Select "Open Command Window Here" or "Open PowerShell Window Here" from the menu.

5. Now connect the LG V30 to the PC via the USB cable. Make sure that "USB debugging" is enabled on the device.

6. Check that a small window opens on the Display, check and give OK.

7. Enter the following command in the PowerShell window to ensure that the device is correctly detected: adb devices The command must return a device ID.

8. Now start the phone in Bootloader mode with the command: adb reboot bootloader

9. Once the device enters Bootloader mode, install TWRP restore on LG V30 with the command: fastboot flash recovery TWRP-3.2.1-joan-v0.1.img

10. Finally, restart the device with the command: fastboot reboot
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
Little update:

Added a version for the people who repartitioned. It can mount/wipe/backup vendor (and also flash images to /vendor if needed) :)
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] rikita:
Step 7 works fine here, gives me the device id, but when I go from 8 to 9 (the phone reboots to bootloader) I lose the connection. Flash command hangs at "waiting for any device'.

Any ideas???
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Pisolo:
"Waiting for any device", does not hear the device.

Check that you have typed well, check that the "USB debugging" is activated, check on the Display if you open a small window and put the check mark (OK), try restarting both the Computer and the device and try again.

It must work.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] rikita:
Thanks for your response. I have checked and double checked all your suggestions, and rebooted both phone and PC many times. Been working on this for 6 hours. Can't seem to find the bug.

Image will not flash in TWRP either. Get a confirmation saying it is complete, but I still have the previous version when I boot to Recovery.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] rikita:
Ok. I got past the driver issue. For some reason when I rebooted into fastboot/bootloader, I was getting an Other Device\Android error in Device Manager.

Went through right-click/Update Driver\Browse\Pick from List and assigned it an HTC driver that showed up and it worked.

Flashed TWRP 3.2.1 and rebooted straight to recovery but I'm still on TWRP 3.1.1-0.

OK guys question I've looked but not found it I'm on v0.1 I flashed no-verity-opt-encrypt-6.0.zip went back into twrp to make a backup everything was good but when I went back into twrp it had the backup folder but it was empty so I hooked to computer and the files were in the folder why didn't twrp see them did I do some thing wrong?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
Did you select right storage (just in case)? E.g. Internal or External? (or even OTG)

If the files are there, it should actually see it.... otherwise, try to copy them from your phone to your pc, and back (maybe even from sdcard -> pc -> internal, or internal to sdcard just in case)
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] foamerman:
I have my storage is the sdcard computer sees the files so I moved them to the computer and then back went back into twrp and no backup file manager on phone says they are there went back into twrp and went into the file manager and it says they are there went to restore file is there hit the file it says select partitions to restore recovery, system, boot, cache, and data. So am I just looking at this the wrong way? am I having a DUH moment
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
When you can select which partitions of the backup to restore, you should be fine to go :good:

Why when i try to restart to twrp the phone go in a black screen with the android logo? If i try ti restart with the button sequence the phone wipe everithing and the twrp doesn t boot. The only metod to boot it is with the adb command via computer
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
Sounds like you never really installed TWRP at all?

If you fastboot flash TWRP at first, and straight boot into Stock ROM again, it will override TWRP with stock recovery. Before you do that you have to boot into TWRP first (either with button dance or with fastboot boot)

There you allow system modifications, and maybe reboot into recovery once or twice again.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] vuoshino:
so what i have to do for make it to boot without the fastboot comand? thanks
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
reboot into bootloader

fastboot flash recovery TWRP.img

fastboot boot TWRP.img

In TWRP:

<allow system modification>

reboot -> Recovery

and then reboot into system again

That should make the recovery stick. Optionally format data and flash no verity opt-encrypt.zip to get rid of LGs encryption (so you can take backups of your data in TWRP), means you need to start anew though with your setup

[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
Fat32 cant handle files >=4GB in size

Can tell you just by that, that youre using a Fat32 formatted sdcard ?

Change to either exfat or ntfs, they can properly handle bigger files.
