Greetings ! Someone can help me with this problem ... I've installed different versions of the operating system (A7 and A8) on the phone (H870) using the .kdz method and different versions of TWRP. I can not get it started in recovery (TWRP) when using cmd I'm giving error and when I use the phone buttons to access recovery, it resets / deletes all the data in it Where do I get wrong?

Probably you aren't even able to unlock the bootloader for that model.

---------- Post added at 10:35 PM ---------- Previous post was at 10:31 PM ----------

You have to enter twrp with the button combo right after you flashed the image file, don't let the phone to boot into the stock ROM, otherwise it'll restore the stock recovery.

I suggest you to try melina twrp that one still more stable and usable imho.

On my H870, I had TWRP 3.3.1 and I could read the contents of my SD Card.

Now I tried flashing HavocOS, (oreo bootloader, havoc, gapps) and now I cannot read the contents of my SD Card.

Since Havoc does not work well, I wanted to go back to my backup which I created on my SD Card.

How can I mount it?

---------- Post added at 07:44 PM ---------- Previous post was at 07:24 PM ----------

The link on this thread is for recovery_h870_20180813-1

The official one is twrp-3.3.1-0-h870

Which one should I use?
[LG G6 ROMs, Kernels, Recoveries, & Other Developme] husky69:
When you have TWRP working on the phone this dialog to erase your personal data doesn't do anything to your data anymore - you have to go through it in order to reach TWRP, but there's no data erased.

That's both what I read about it and my experience for quite a while.
[LG G6 ROMs, Kernels, Recoveries, & Other Developme] mn1968:
I have an LG G6 H872, I rooted with this guide and have TWRP installed (same as linked in OP). I have created several backups since with TWRP.

This morning, I inadvertently messed something up and my SystemUI kept crashing. I booted to TWRP , wiped data, system, & cache, and restored my backup. However, when the phone rebooted, my phone wasn't restored. Instead I had to set it up as new. EVERYTHING! I've been rooting and backing up/restoring with TWRP for years but never had this happen. What's the point of backing up if I have to redo everything?

Sorry...end of rant!
[LG G6 ROMs, Kernels, Recoveries, & Other Developme] mn1968:
After researching more about TWRP, I believe that my issue is because dm-verity is/was not disabled. Does this sound right? In the rooting guide I followed there was no mention of dm-verity ( I followed the guide to a "T"), so I have to assume it is not disabled. If I were to flash a dm-verity disabler, would that wipe the phone again? I'm not looking to set it up again from scratch. If so, I guess I will just make backups by selecting System Image rather than just System, per this page.

Thanks!

Also, is there a difference between no-verity-opt-encrypt & DM-Verity disabler? They seem the same to me but I could be (and am likely) wrong.

PS: FWIW, I am running stock 8.0 with Magisk and a few tweaks.
[LG G6 ROMs, Kernels, Recoveries, & Other Developme] mn1968:
Me again. I have tried multiple times to create TWRP backup with

System Image

and each time it fails. No error code, nothing...just ends with "Backup failed. Cleaning folder". However, backups with System complete successfully. Of course, I don't trust to restore with the System backup based on my experience from a couple posts up.

Any thoughts?

Thanks!
[LG G6 ROMs, Kernels, Recoveries, & Other Developme] AlDollaz:
Just back up system. No need to backup "system image."
[LG G6 ROMs, Kernels, Recoveries, & Other Developme] mn1968:
That's what I had done but when I restored, my phone was not restored to it's previous state. I had to set it up from scratch again. Very frustrating! From my research I believe it's because the phone is encrypted/no-verity is not disabled - although it shouldn't be since I followed the H872 root guide. I've read that "System Image" works well for restoring phones with no-verity. I'm just looking for answers.

Thanks!

Boot

System

Data (excl. storage)

Hi all,

Sorry for my bad english, im stil learning. Plus im fighting with autocorrect.. a mean beast.

My H870, prompted pin request last week, 10 attempts. I tried 5 times and my phone is now dead locked.

Can i use twrp software just to unlock screen lock ? If i will root Android or smth, i dont care. I want my data, photos and other stuff back.

And i am a little bit scarry, dont know what or how to do it. Can someone write me an instruction how to not **** up this recovery into real disaster like completely destroying phone or smth..

Or maybe there is an instruction, just my dumb ass can't find it..

Please help me.

Same issue here on LG G6 H870 with Havoc 3.1 / Android 10
[LG G6 ROMs, Kernels, Recoveries, & Other Developme] Sobek5150:
This is likely an issue with TWRP as a whole right now. If you check out their website they have a post on A10 development and it could be a while. Alot of locations of files changed with A10 especially considering our device is considered system-as-root.

You're not alone. I've done extensive testing to get this to work and cannot and it comes down to the system partition. Something in the twrp process of restoring system isn't putting files back in the same places or something.

A work around that I found is to wipe cache/system/data/dalvik and reinstall the same version of Havoc/ROM, gapps, and Magisk, wipe caches then restore your Data partition from the backup. This allows the system to reinstall properly and then you restore your data on top. Word of caution though, I've had varying results with stability after doing this. It reboots no problem but one time I had system ui start to crash a couple days in for no reason. Just be aware!

---------- Post added at 11:47 PM ---------- Previous post was at 11:39 PM ----------

This used to be Eliminater74's version until the new OP asked to take it over and continue development. That of course didn't last. New OP released one new version where he decompressed the boot so that TWRP would load faster than before, but in doing so it messed up the date and time system again. So tradeoffs I guess..

I guess if you had to give it a name I'd call it the Eliminater74 version. Others out there are Melina, Orange Fox, and maybe one more in the forums. Most all the development is dead now the device is reaching 36 months after release. With that said, Wolf - who builds Havoc - has been hoping to get new TWRP versions built for all three unlocked variants - H870, US997, and H872. No guarantees though!
[LG G6 ROMs, Kernels, Recoveries, & Other Developme] Vortell:
Yeah this is behind by a version most are in 3.3.1

Which I is generally needed for a10... for app backup/restore have you tried migrate custom ROM back utility?
[LG G6 ROMs, Kernels, Recoveries, & Other Developme] Sobek5150:
I actually use Swift Backup. Used to use titanium but it's had problems since mid last year restoring apps properly. Migrates flashable zip is enticing but either way I do I (because Swift automates the restore too) theres just more than I care to do. Some days I test multiple versions of Havoc or another rom for the guys building. I found that it's just a hassle to not have a good backup to come back to. So I have a Pie backup that I use when I have to heavily test since I know the backup will restore properly.

Hello guys

I have H872 with bootloader unlocked

I treid flashing recovery but i get "Failed (remote : unknown command)"

[LG G6 ROMs, Kernels, Recoveries, & Other Developme] Vortell:
I always suggest using migrate first. I don't know enough about Swift backup to suggest it. I have seen it but don't know if it's open source. Don't like titanium much cause if that too. The best way though is still adb/fastboot tell it is removed. At least when TWRP isn't working.

Will this twrp version work on Android 9 H870 LG G6? The software version is 'V30b-EUR-XX', not rooted.

I've tried to install the latest official twrp using fastboot, but it would't start, the phone just boot up normally after I select 'yes' when i'm asked about data erase after button combination.
[LG G6 ROMs, Kernels, Recoveries, & Other Developme] Sobek5150:
Should work. However if it does not, you could go to TWRP official site to download the H870 recent version. Hopefully that one will work.

If you plan to flash A10 custom roms later you'll want to upgrade your recovery to either Orange Fox or SkyHawk recovery as they support backing up on A10 where as the main TWRP we have for this device is built for Pie or earlier roms.

Don't worry : turn back to the last official rom and use your phone.
[LG G6 ROMs, Kernels, Recoveries, & Other Developme] xabzzz:
Just in case, I'm using v30b global (stock rom) and I don't care anymore about security updates. Security patches are certainly useful but not essential, unless you are a FBI agent, or a boss somewhere and so on.

I don't use anymore custom roms. There's always something that does not work well with them.

LG G6 h870 is a great phone for ... calling, etc., etc. + TAKING PICTURES.

Besides, TWRP is known to ask for password ... (some kind of bug I guess).

You can install it, and then, install OrangeFox over it. OrangeFox is known to deal with the problem of Passwords.

Finally, if you only use TWRP, when asked a password, you just "cancel" and go forward ...

It got me to boot loop, so then I patched recovery with the same patched magidisk and at the same time I patched boot with boot.img from unoffical H870-V30B.zip.

@Eliminater74

Hello, for beggining, huge thanks for your hard works :good:

I have just tested your latest version available via your link in your topic (recovery_h870_20180813.img).

By the way i prefer the welcome image you put at the TWRP launch compared to the default one :)

As for the features, i can't test either encryption or kdzwriter because i completely disabled encryption, and i'm not on stock.

Regarding the data backup feature including other directories that you marked "Beta" in the backup section, it did not work for on my phone, nor don't i know exactly what directories this feature contains.

There are the two log files, one when the backup is done with this famous "Beta" option checked, and a second log file without this function:

https://drive.google.com/drive/folders/1FiijopA1f4ep4hnvOVd_99zzv0HH2twO

I also note that time synchronization works perfectly, which was not the case on some versions of zefie.

Concerning the function of deleting security measures when restoring data, i will be able to test this when i have a little more time.

I also took note that you made sure that more partitions were listed when setting up a backup. Would it also be possible to know if a backup with all possible data is necessary on stock or with a customized ROM?

Thanks again for your work :)

I just got root and twrp on my h872 a few days ago using a very slightly modified version of [MENTION=3167089]runningnak3d[/MENTION]'s procedure for lollipop.

I have twrp in laf and recovery so im willing to test this out and flash it over recovery tomorrow.
