Well it's coming from g-drive and maybe it's just me but I've always had slow downloads from there.

Plus if we're talking about that kdz file I was honestly surprised on how large it was.

(if somebody says, "that's what she said" I'll thank you. Lmao) [emoji12]

I was having the same issue in a way, except the file would start downloading, hit around 130mb then if I went to something else and came back it was starting over.

Note : I was using that aloha browser (experimentating) to get it and had changed my dns settings. No sure how much of an affect that had on it.

My up speed is nowhere near as fast as my download speed so it'll take a minute but I started the upload, it was the h872 kdz you wanted, correct? Link: https://www.dropbox.com/s/lpu8kd5gi5s994f/H87211g_00_1218.kdz?dl=0

It works to mount it as read only, the issue is that I can't mount it and the check box for mounting the System partition does absolutely nothing other than just spitting out the previously posted errors in console.

Yes that's what I was looking for, thanks for uploading that! It must've been a chrome issue cause it was doing the same thing when I tried downloading from your link. I used Firefox, and everything went fine. Gonna try to root this thing tonight!

This method def. works to restore laf, but it is not safe to use these file paths because directories under soc will have a different name on every device. it is best to dd the laf files to /dev/block/bootdevice/by-name/laf and lafbak
[T-Mobile LG G6 Guides, News, & Discussion] ryanrod:
Forgive me for being such an !npc ;) but can I flash this safely if my underlying stock rom was 11g? I never went to 11h or 20a, just straight to the AEX rom. Thanks.
[T-Mobile LG G6 Guides, News, & Discussion] weakNPCdotCom:
I'm not sure if the 20a laf is compatible with 11g or not. But I can try to make an 11g laf image later tonight
[T-Mobile LG G6 Guides, News, & Discussion] ryanrod:
Thank you, that would be incredible! How do you do that btw? In recovery or extracting a kdz?
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
[ROOT] H872 (up to and including 20a)

Well I did it the hard way. Went to stock 20a downgraded & rerooted, followed the steps in the op up to after running ./step1.sh I also included all that was worked on to get data to mount. Still running that 918 used to root I'd assume.

I'm not getting the password encryption garbage anymore but I've noticed occasionally something won't want to flash correctly and if I go to recovery system isn't ticked under the mount option.

I've ticked it and flashed something right after & I've also rebooted after ticking it. Either way the phone runs fine and seems to flash whatever. With that one caveat.

I do notice in tbpro that I'm only seeing 2 storage whatever y'all want to call them. Where I've always seen 3 after rooting before.

I'm still running aex not the latest rom but a different kernel than what's usually in there and so far its running like it should.

Miss my assistant though. Won't do the unlock to voice bit. Custom rom thing maybe? Haven't started digging into it yet.

Honestly if I didn't have that data mount issue on stock 20a that rooted would be nice. I like all the custom features but sometimes like the fp deal you don't know how used to something you've gotten till you can't use it anymore.

I didn't keep as good a track as I should've during the process admittedly. I may even redo things just to see but, unless y'all tell me different from what I've said in this long freaking post I'll be staying where I'm at for the moment.

Wouldn't mind sorting out the whole laf thing though. I could do all that adb if up against a wall but if there's a way around it I won't lie and say I'd rather go that route.

Flashable img like twrp is to put on recovery would be cool. Don't see where it wouldn't be possible but it's been awhile since I've gone into things that far.
[T-Mobile LG G6 Guides, News, & Discussion] ryanrod:
Yeah, since you are on 20a as your base, just use the flashable stock 20a LAF zip which is already available from weaknpc. I believe this is how it works: First make sure that TWRP is flashed to the RECOVERY partition as well as the LAF partition. Then go into TWRP and flash this zip to get 20a stock download mode back on the LAF partition. See below.
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
Been there and couldn't get it to flash. It's been a couple days so I can't remember if it threw me an error or what. I couldn't get the zip to flash and he said to extract so I tried it that way with no luck. I just flashed the stock 20a and went through it all again. But couldn't stay there because of the storage issue. So for right now it seems ok. In fact after this I'm going to boot to recovery and see what I see.

Please, create flashable zip with 11h bootloader + modem.
[T-Mobile LG G6 Guides, News, & Discussion] jpgonzal:
I am trying to understand the difference between the h872 and the h870. Why is rooting so much harder in the h872? what would happen if attempting to flash twrp using "fastboot flash recovery twrp.img" or "fastboot boot twrp.img"?

Thanks in advance!
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
Nothing command isn't there. The boot twrp.img is supposed to work but I've never run it. The usual fast boot flash blah blah that you'd usually root with don't work on that phone

I'm going to be working on a stock 11g and 11h rom this week. I'll post what I'm able to get done.

Curious why you just need bootloader and modern
[T-Mobile LG G6 Guides, News, & Discussion] DmytroPitenko:
because the fingerprint does not work on custom ROMs with 20a bootloader
[T-Mobile LG G6 Guides, News, & Discussion] weakNPCdotCom:
Ok. FYI I've tested fingerprint in aex and flashing the bootloader with 11g or h doesn't work on this phone.
[T-Mobile LG G6 Guides, News, & Discussion] DmytroPitenko:
Maybe this help you

https://mega.nz/#!v8ViASbT!97ZiIYwu3YcDGPy2zaFiFEVh8z2xI8ccrzICc6KR5Xc

With this zip I successfully updated the bootloader to version 20a (for use with stok Oreo, with 11g bootloader FB doesn't work on Stok Oreo)
[T-Mobile LG G6 Guides, News, & Discussion] weakNPCdotCom:
Sorry I guess I wasn't clear enough in what I said.

I tested going from stock 20a to AOSP Extended and FP wasn't an option.

I then tested flashing the stock 11h bootloader over 20a, and going to AEX and FP still didn't work.

I flashed the entire 11g stock firmware before flashing AEX in order for FP to even exist as an option in the custom Rom.
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
I went exactly the same route and it's working for me. Didn't do that laf replacement. Your prep with going back to stock, then op inarticulate for 11g until you finish step 1.Sh in fwul. Then the rest was following your instructions from that night.
[T-Mobile LG G6 Guides, News, & Discussion] weakNPCdotCom:
Took a sick day today and I'm going to put some 11g/h packages together and see if I can't cook up a boot image with encryption disabled for 11g.

---------- Post added at 12:59 PM ---------- Previous post was at 12:53 PM ----------

The 20a version was a TWRP backup from my phone after I restored stock laf using adb shell. But I cant flash every ARB01 version just to make an laf backup, so i extract the dz files in the kdz package and then make a flashable zip file.
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
Hey man you still on aex? Not going into it more unless it's no big deal, but are you able to unlock with assistant? Or even activate it by voice? Just curious if it's only me.

Thanks for what your doing and the help you gave me I know I've said it before but it means something (ya I'm one of those old time people that appreciate stuff like that)

Your a good guy Charlie Brown [emoji12]
[T-Mobile LG G6 Guides, News, & Discussion] weakNPCdotCom:
Ha thanks man. I am still running aex, but I haven't set up assistant or anything. Don't really use it. I can try to test it out at some point though

Just finished a stock 11h rom and no-verity, no force-encryption kernel.

About to pack up 11g. Trying to decide whether or not I want to test them all... Don't really want to... But.. Lol
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
I get ya. No worries on the assistant thing I was just curious. Use it when driving mostly. I'm not even on an updated version of that rom yet. So you never know.

Personally think what your up to is important when it comes to this particular device.

A year was too long and allot of stuff that normally gets taken care of like what your up to is done right off the bat. And ends up making it so other things can happen. Like how dude is trying to integrate the stock stuff into that rom.

Help me downgrade without root or twrp

i own h872 on oreo.. and gaming sucks on oreo.. so i want to downgrade nougat 11g.. i know i cant rollback below 11g because of anti roll back.. so i intend to downgrade with lg up and uppercut.. so let me mention the steps and correct if i am wrong

1. unlock bootloader in fsatboot with usb debugging and oem unlock

2. install lg up and uppercut on pc

3. switch off the phone and put it in download mode

4. open uppercut with admin rights and it will open lg up and detect my phone

5. On lg up i select "Refurbish" option and select my 11g kdz for nougat and press start

6. and my phone shall start downgrading and boot into setup screen right ?

i just wanna know these steps work or not... i dont want to flash laf partition because i am not going for root.. i just want to downgrade and relock bootloader again.. help me guys...
[T-Mobile LG G6 Guides, News, & Discussion] ryanrod:
nice.... lightbulb just went on above my head... thanks...
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
Without looking through the whole process again there's one thing I caught I think in your list.

Somebody may need to back me up or say I'm wrong. But I don't believe the stock version of lgup will do the job. The version used in here is patched to work with this phone. And doesn't get installed like it normally would. (check op)

Mind you this is first thing in the morning so I'm not even through a cup of coffee so double check me. It may be that just going back to stock without root you won't need it but idk for sure.

The rest of it sounds right to me, but again double check. Screwing something up makes everything a total pia.

Also, check on relocking the bootloader.

I thought I read somewhere the doing that would brick the phone. Seems silly to me but thought it worth mentioning.
[T-Mobile LG G6 Guides, News, & Discussion] weakNPCdotCom:
Ken is correct. And unfortunately the stock roms I cooked up don't work. They bootloop and I'm not sure why. So I'll have to try again
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:

Rooting Failed at ./step2.sh

I ran ./step1.sh it flashed successfully on 2nd attempt, then remaining 3 attempts just went until all timed out. Then I ran ./step2.sh , It says rooting booting back to TWRP, dont do anything untill come back to OS.

then all unmounting and flashing messages, pushing magisk16.zip,

phone will reboot back to OS once rooted and final now you can install magisk manager....

I had 1st reboot twrp screen with "Mount dycrypt data" cancel select language. It doesnt go to OS it stuck there.

I cancelled decrypt mesg, allow modification, rebooted back to twrp (I read that by rebooting back to twrp it will stick), then rebooted to system, Oreo asked for reset phone - secure boot encryption. I reset back to oreo installed magisk manager but NO ROOT.

Completed same process twice same result no root at ./step2.sh (refer below image URL)

https://i.postimg.cc/j5J27zZW/IMG_20180926_224032.jpg

Please help.
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
Try installing magisk and twrp without running the step 2 command.

You can look at the fun I went through if you'd like to. I was on 20a when I rooted and I ran into all kinds of problems. I'm heading out the door or this would be longer.

But ya, look for the posts I put up and the guy I was talking to about it. Your answer could very well be in those posts.
[T-Mobile LG G6 Guides, News, & Discussion] weakNPCdotCom:
Not trying to come off as a jerk here, but it doesnt sound like you read the instructions for Oreo. There are several warnings about having to manually flash twrp and magisk, as well as having to format data in twrp in order to remove existing encryption on the phone. Please try again, and be sure to read everything.
[T-Mobile LG G6 Guides, News, & Discussion] mannunikhil:
Since TWRP on laf so flashing from there wouldnt make issues, right? What should be the sequence 1st twrp.img then magisk.zip? Does USB storage get detected on this twrp or should use external_sd?

I am on Nougat 11g
[T-Mobile LG G6 Guides, News, & Discussion] weakNPCdotCom:
I assume you flashed an oreo rom then since you referenced oreo. In either case, use the TWRP that you installed to your laf partition by booting to DL mode. there are encryption issues with TWRP, and in order for it to successfully mount the vendor partition and work right, you are going to need to do a format data under the wipe menu. afterwards, you will be able to mount and flash. At that time, manually flash TWRP to the recovery partition, and magisk. I am personally on magisk 17.1 running stock 11g base. step2.sh is not 100% working due to these encryption issues.
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
I ended up on stock 20a myself. Out of nowhere I'd lose root or catch a bootloop only way I could get it to run right was the zip plus magisk to keep root. Been running fine for a few days now.
[T-Mobile LG G6 Guides, News, & Discussion] mannunikhil:
My bad in panic I wrote Oreo. Anyhow, done all steps like format, wipe, twrp install, magisk zip install, reboot ok without encryption notice this time and magisk manager confirmed phone rooted.

Installed few root checker apps, rebooted phone and root gone again. Is this weird?
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
When you go into magisk and the modules option from the menu hit the 3 dot deal on the upper right and see if it gives you the option to reboot to recovery.

My first guess would be if you don't have that option that twrp is getting overwritten at boot.

You did install twrp to the recovery partition?

I was having error issues myself. The twrp if its still the same (haven't heard different yet) was built for 8.1 which some of us think may be the root cause of these issues.

For me. I even thought I'd lost download mode because every time I'd try to boot to it I ended up at the fastboot screen which you shouldn't see after installing twrp to the recovery. Let's just say lots of French words came out of my mouth before I worked it out.

I ended up rooting then installing the oreo zip that's in the t-mo section of threads for this thing. Then had to install magisk on top to keep twrp from getting overwritten at boot and it seems to have solved those issues.

I'm on the h-872 by the way. It's been noticed for example that the 870 of the device seems to have something different about it causing hiccups but I didn't get that from this thread and since I don't owe it I can't investigate.

Anybody know better let me know. If I'm wrong then I'd want to know so I can learn why and how to fix things.
[T-Mobile LG G6 Guides, News, & Discussion] mannunikhil:
There has to be something several ppl are having root in their H872. What version of Magisk is keeping rooted thats what we have to know. I used latest 17.2. :rolleyes:
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
I may have some too soon at least about the decryption thing.

But I am still rooted and I'm running 17.1
[T-Mobile LG G6 Guides, News, & Discussion] mannunikhil:
You got root working on Oreo with 17.1. How was your experience for nougat 11g for 17.1? You reckon I should try magisk 17.1 on 11g?
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
That's where I was when I ran into all the issues I can't say that it's TWRP or anything else because I'm still getting the decryption issues. I went to flash something through Flashify yesterday, booted to TWRP and gave me the decryption password message. The funny part is everything seems to flash and work even though I'm still getting that message. What does that? I have no freaking idea.
[T-Mobile LG G6 Guides, News, & Discussion] weakNPCdotCom:
I don't know why you keep running into this encryption issue Ken. I don't have the encryption message on my phone after formatting data, rebooting to recovery twrp and flashing magisk. are you restoring a data backup? if you're backup is encrypted that might be why. when I start over with apps from scratch after formatting then I no longer get the password prompt
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
It's the strangest thing. I've never encrypted the phone. I've done formatting like crazy. I swear I've gone through the root procedure multiple times. Can't have done something wrong every time? Lol... Magisk doesn't seem to have issues with running any of its modules and I thought I was fine until I did that Flashify deal yesterday. I've been running it through in my head trying to think of a step I may have done wrong.

Just right now had a brainwave and don't know if it'd count.

Before root I've used "Island" and other apps like that using the adb commands to get them to work. I've used app to sd card apps before and after root. Haven't this go around though.

I'm wondering, if the user commands within these said apps or the function itself of the app could've done something?

Funny thing is almost every time I've run into some issue of this type I've been able to work it out. I'm wondering if I were to use a never mounted SD card if that would have any affect.
[T-Mobile LG G6 Guides, News, & Discussion] mannunikhil:
Yeah, I get decryption message everytime I go to recovery. And also, I noticed sometimes Magisk manager shows full home screen details and sometimes it doesnt show that magisk is installed.

I think I should go back to Oreo 20a with no root like earlier. since it is also ARB01, there wont be an issue in "upgrade" 20a kdz, right?
[T-Mobile LG G6 Guides, News, & Discussion] weakNPCdotCom:
you need to use the patched lgup and use partition dl instead of upgrade. but yes that will be fine
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
[MENTION=9374982]weakNPCdotCom[/MENTION] don't know if you caught these two posts but I was curious what your thoughts might be

Just thinking out loud again. If we're wiping system as I've seen others mention which I've also done then flash the 20a zip then the device should be a clean slate and if I can go into recovery without an issue right after rooting the problems pop up later on.

I'm still thinking about the apps or any way I may be restoring data without being aware of it.

I'm starting to think the only thing that could be doing that is allowing Google to auto restore your apps as you setup the phone.that's the only place I could figure it happening. I'm pretty sure the last time around though I restored apps from a backup. Maybe I restored data accidentally?

I'm using tbpro for back ups so it's easy as it'll ever be to give it another try.
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
Sorry it took so long. I'm not totally sure on the arb deal.

I'm thinking of it's not 0 you should be able to roll back no issues. But don't quote me on this.

But I have noticed magisk acting as you've mentioned once or twice. (I want to say a reboot fixed it but if me lying if I said I was 100% on it)

There's a 20a zio or that once you get step 2 done and can boot into twrp you can flash that "seems" to get revert everything in one go.

This is what I did :

*Wiped everything that seemed safe (dalvik, cache, data, & system. May or may not have done the format data but in the main wipe screen but think I did.

*I flashed that zip

*Flashed magisk to keep twrp on the recovery. (Which i wanted) and root and rebooted to system.

I seemed fine until something occurred that I believe I may have done (recovery of data within an app?) Idk but I had full stock with root.
[T-Mobile LG G6 Guides, News, & Discussion] weakNPCdotCom:
As a rule of thumb, whenever I flash a rom or firmware, I always flash magisk after. just in case there are changes to the boot image that overwrite magisk or it's configuration.

like I said, originally I did this on 20a stock kdz firmware. and then recently I reverted to 11g kdz so I could flash the aex rom.

firstly Ive always started from a stock kdz..I haven't used the 20a stock rom

secondly I never run step 2 in FWUL. I always push twrp and magisk to my micro sd

boot to TWRP on laf (dl mode)

format data.

reboot to laf again which will mount data automatically, or manually mount system and data in twrp

flash TWRP to recovery partition

reboot to recovery which should boot to TWRP

flash magisk which should disable dm-verity on the boot image

after that I usually boot to stock and install magisk manager and make sure it is all updated. then I boot back to recovery, flash a custom Rom, flash magisk again.

if it's the first boot after removing encryption, I set everything up from scratch. I don't restore anything. then when I confirm that TWRP no longer asks me for a password, I make a full backup. then I know if I restore data it won't be encrypted.

I would try just running through whatever steps work for you that initially get you root access, and just make sure you flash magisk as the last thing so you are certain the boot image hasn't been touched again
[T-Mobile LG G6 Guides, News, & Discussion] weakNPCdotCom:
this is what my Magisk Manager looks like, but my data is not encrypted
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
Same here. And I pass the checks and all that.

I keep coming back to some app I reistalled restored data and that somehow weirded it out
[T-Mobile LG G6 Guides, News, & Discussion] weakNPCdotCom:
and also, 11g, 11h and 20a are all ARB01 and safe to upgrade/downgrade between. anything prior is ARB00 and you cannot go back once you are on an ARB01 image
