Now I've unlocked bootloader on H815...

Can anyone please give me any helpers on the easiest way to Root and install TWRP on my H815, Im in the UK and Im running MM 20a official rom.
I have rooted other phones but not this is a new phone and isn't as straight forward as my G2 was.
Thanks in advance.

I think I need to be already rooted to use this method, dp I not ?
I need to root and install twrp.
When i had my G2, the forums was buzzing with new Roms, it was pretty much a bullet proof phone, i was hoping for the same with the G4, pretty gutted that its so quiet in these forums for this phone.

No. Just install twrp. Reboot into twrp and install supersu. Be sure to not let twrp auto-install anything to root your phone.

Hope your TWRP sticks, I'm new to this and it took me 3 attempts to get it to stick.
To get into recovery
Hold both power button and volume down button pressed
At first sight of LG logo release power button 1 second, Still holding volume down, then repress power button.
You should now get white screen with just 2 options, select "Reset" , Select with Power button, scroll with volume up/down
Again get white screen and confirm reset
If TWRP is on phone it should now appear.
If its not you are in for a Factory Reset
:
Now do a default backup in TWRP (very handy this)
Then move systemless root zip to phone.
In twrp select install find your "systemless root zip " flash , then reboot using "System" DO not accept option to root your phone offered after selecting- reboot>system.
Hope its goes well

I am on the same boat as OP. I unlocked the bootloader after updating to Marshmallow, so I didn't have TWRP from Lollipop. Now, even though it says that the flashing went okay, there is no recovery to boot into. Using "adb reboot recovery" it shows the android logo with the exclamation mark. If I do it using the hardware buttons, I get the LG's menu to wipe everything or exit.

If you have root there are many apps on play store such as : quick boot, simple boot, quick reboot. Install one of these and and they all all have options for reboot, hotboot, boot to recovery, etc. etc.
I have TWRP on my phone and if I use the standard way to enter recovery , power+volume down, then I will get the standard LG recovery screen but when I accept the recovery options there, it takes me to TWRP

That's the problem, I don't have root. I need TWRP to flash the SuperSU zip, don't I?
EDIT: Wait, do I need to say yes on the stock LG recovery first? The one that says wipe everything?

@ Dante897 No, if you don't have TWRP then don't. don't say yes to LG Recovery or you'll loose everything . You can also run TWRP on your PC and install systemless root zip that way. That maybe what I did, I can't exactly remember now.
I'm off to bed now, last night was a late night too.

I figured it out. You aren't supposed to flash the recovery., you are supposed to boot to it, flash SuperSU and then use Flashify to install TWRP. I did that, but I flashed the wrong SuperSU (I am an idiot I know) and my phone won't boot now. Currently I am in download mode and downloading the rom with LG Bridge . You can follow the guide here if you want http://forum.xda-developers.com/g4/general/unlock-bootloader-install-twrp-root-t3128241 but whatever you do DO NOT flash SuperSU 2.46, grab the newest from here http://forum.xda-developers.com/showpost.php?p=64161125&postcount=3
I cannot say that it will work, all I can tell you is that 2.46 certainly doesn't work.
EDIT: Alright, I let LG Bridge install the update, no wipe happened. I did the process again, this time I flashed SuperSU v2.62-3 and everything went well and my phone is now rooted.

I also had an issue with TWRP sticking. I followed someone else's tip and you have to have the twrp IMG saved on your computer and also on the phone before flashing recovery with fastboot.

Urgent Help: Can't Upgrade or can't Go into recovery mode

Hi. I have a weird issue. I have a D855 phone which is running on kitkat v10n. I thought of Upgrading it to official 5.0 or 6.0 firmware and decided to check for the option software update in my phone. But I didn't find any. So i thought of installing TWRP recovery to my phone. and I flashed through flashify and cant boot into recovery menu but i can see fastboot menu started and some other 2,3 lines at the top left corner of the phone. I cant even reset the phone also as doing that going into same fastboot menu but when i pull the battery and place it it is booting.
The real thing starts from here. I want to check whats wrong with my phone and found that actually my phone motherboard is LS990.Not D855. So I came to know that as i wrong flashed the recovery, I am getting fastboot mode. So can I flash tot file directly now or not? if doing so will it result in hard/soft brick or in boot loop? Please help me to upgrade from kitkat to lollipop without any damage to my phone. Expecting a resolution from you. Thank u..

Can you still boot into download mode or not?

You did not see the upgrade because either your sd card is full or too small for update to fit. Happened to me once. When you sort this up, make some room on your sd card and then let the OTA do the thing.

If you can boot into download, it would be possible to flash kdz. Just you must find the right one for your phone!!
Edit: you will have to use LG flash tool. LGUP is only for D855.

no.for ls990 there is no kdz i think so.only tot and dll files.but i am doubtful in flashing anything before fixing the fastboot menu as i could brick my device if anything wrong happens..

Ufff.
This is the hard way but at least first you check your memory for errors, and somewhere in the text it clearly says that fastboot is a no-go.
http://open-freax.fr/guide-unbrick-your-lg-g3/
I personally would go with a download mode and tot files, AND DISBLED ALL THE THINGS THAT WANT TO KILL PROCESSES. like antiviruses, win-defender etc.
Trust me, I know how you feel, maybe some more ideas drop into the thread.

So lets explain few things first. You can safely flash tot files via download mode. Tot file contains your stock recovery partition as well. So everything will be flashed to stock. So if you find tot file to flash for your model fell free to flash it.
Instead what I would suggest is for you to flash TWRP, and after that flashing Lollipop zip with TWRP.
Here is how:
You download TWRP zip for LS990 from here if you are sure that's your model:
https://www.androidfilehost.com/?fid=24052804347763136
then you extract recovery.img file from the zip,
then to flash it either use flashify or these adb commands:
adb shell
su
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/recovery
dd if=/sdcard/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
Ofc if you use these exact adb commands you need to place recovery.img to root of your /sdcard.
So now you confirm that you have a working TWRP. Try to boot into it.
If it succeeds you have Sprint Lollipop files provided here:
http://downloads.codefi.re/autoprime/LG/LG_G3/LS990/stock_partitions/ZVA
You only need these files: system.img, boot.img, modem.img, rpm.img, tz.img
IMPORTANT: boot.img you download from here not from the link above:
http://forum.xda-developers.com/attachment.php?attachmentid=3165683&d=1423941988
After downloading them and placing them in root of sdcard, boot to TWRP open terminal and write these:
dd if=/sdcard/system.img of=/dev/block/platform/msm_sdcc.1/by-name/system
dd if=/sdcard/zv8_boot_fixed.img of=/dev/block/platform/msm_sdcc.1/by-name/boot
dd if=/sdcard/modem.img of=/dev/block/platform/msm_sdcc.1/by-name/modem
dd if=/sdcard/rpm.img of=/dev/block/platform/msm_sdcc.1/by-name/rpm
dd if=/sdcard/tz.img of=/dev/block/platform/msm_sdcc.1/by-name/tz
That's it.
Credit for these files goes to the OP of this thread @autoprime

I assumed that system.img was provided in links above. It isn't.
So here:
http://downloads.codefi.re/autoprime/LG/LG_G3/LS990/stock_partitions/ZVB/
Download zips only. Flash them, no need to use dd command. It is prerooted Lollipop. Again credits to @autoprime.

I would wait for MM to settle a bit, some guys have icons problem, some LTE, some stuff is downgraded to work properly. How ever you go, you will not get clean MM. Only if you do not want root, and that is a no-no for me.

I flashed it but after booting android process is force closing for every 5 seconds and its showing the same message. So I went into recovery menu, wiped dalvik cache and cache,data and system and made a factory reset again and rebooted it. But my phone stuck on LG logo only. Now i can't even enter into TWRP Recovery . What to do?? Flashing tot is only the solution? I can go into download mode..
Edit: I tried going to TWRP manually. First I tried by going to recovery mode by watching a video showing holding volume down+power button and release after the LG logo is seen and within half second again should hold back. That didn't work for me. I only holded volume down+power button untill I see "Recovery mode loading" screen and after 2 seconds it taken me to TWRP. I successfully re-flashed back the zip files again. Thanks for your help. but i am getting invalid sim and showing hands free activation on my phone.. So should I need to unlock it?? now big trouble with the sim problem.Can u provide any solution??

Troublesome. I have no knowledge what "hands free activation" is. I belive it's something connected with Sprint?
As for the invalid SIM, was your phone SIM locked? Where did you buy it and why did it even have d855 system flashed onto it if its ls990?
Can you make calls and have you made a backup of your old system in TWRP before flashing?

I followed one link and replaced some files and got the signal back. But I am unable to access data in my phone. also in settings i am seeing activate this device. I disabled hands free activation thing which is very annoying. But flashing any other lollipop rom, can I use data in my phone? Can you suggest any best lollipop rom like cloudy or other than cloudy?

twrp problem

Hi anyone can help me. Before i restart my device it automatically boots in bootloader mode. I manage to fix it via fastboot command "fastboot oem fb_mode_clear"
But after that my problem now is when i restart my device it boots on twrp recovery. When i reboot system it also goes back to twrp mode. What is this problem? Any fix for this? Thanks everyone.

To flash in TWRP you need to flash it as an image, the option is in there. It will allow you to flash an older or newer version when with in TWRP.

Yes sir. I have 4 different roms in my sd card. The aex, xperience, crdroid and aokp. Im in aex rom before everything is smooth no error when restarting. Until then i decided to try the aokp rom 05/21 nightly build, and after that i flash also a modified boot logo to get rid of the unlock bootloader warning iflash it using fastboot commamd but when i power it on and set up the aokp rom everything goes well but then i need to restart my phone then the problem now is appearing. It directly boot in twrp recovery.

Honor 7X Oreo Stock Recovery

Hi, I manually updated my honor 7x (BND AL10 INDIAN) to EMUI 8 following the other post in this forum and after that I went on to flash TWRP recovery again from another post "complete_twrp_ramdisk.img" so that I could take full Nand backups and what not. But Here's the problem, When I try to flash the stock recovery back "BND_RECOVERY_NOcheck" which I flashed during upgrading to EMUI 8, it says "size of image is large than target device"
I tried this using boot fastboot command "fastboot flash recovery_ramdisk recovery.img" and also using the TWRP. It doesn't work either way. So I'm basically stuck with TWRP. The reason I want stock recovery is because
1. I can install OTA UPDATES on EMUI 8 (I actually got one)
2. I may want to just be on complete stock like locked bootloader, sock recovery etc...
Could any one help?? Maybe I need the right stock recovery file ?
BTW It's my first post ever so please go easy if I did any mistakes.

Could you share your twrp? Thanks!

"BND_RECOVERY_NOcheck" is nouget stock recovery.
Oreo update replaces all the partitions, including the recovery that you flashed in order to install the update.
The stock recovery can be extracted from "update.app" , the one inside the oreo "updateL22.zip"

Hi, I'm downloading that UPDATEL22.ZIP right now and Can I extract this with any unzip/unrar program? What will be the name of that recovery? is it going to be "recovery"? The thing is I've never extracted anything from a ROM so I have not idea.

you should already have the update.zip.
use same one you "manualy" installed.
winrar did not work for me but 7-zip did.
there is also rom extractor built into "multi-tool" and stand alone extractor around here some where.
I found it here
the name is just like the twrp you flashed and just like the partition that you flashed. (recovery_ramdisk.img)

Hi, Thanks for all your replies. After doing a bit of search, I managed to get it extracted on my android using zarchiver app and I copied the recovery_ramdisk.img from that BNDL22.ZIP and when I tried flashing it using the fastboot command "fastboot flash recovery_ramdisk recovery.img" It went ok and It got installed but when I tried to boot into recovery, I got this screen "ERROR MODE" ATTENTION ETC.. I don't know where I'm going wrong?

I dont know.
The new way to boot to recovery was written in other thread as "hold both volume buttons & power button"
not sure if it was a problem with extraction or not, but attached is the recovery I extracted. do not have it installed. I dont even have oreo installed., I'm still pulling files together and reading the update-scripts and trying to convince myself if it is worth trying it.
https://www.androidfilehost.com/?w=files&flid=262391
I have now jumped on board and did oreo conversion on L24, then flashed RR. I went and installed the oreo recovery, then back to this stock recovery. It worked fine for me.

Hey bro thefe are too many files there will it flash through fastboot or twrp and how to flash one by one pls help me

Hello all,
thanks for all the info in this thread.
I bricked my Honox 7x (BND-LC21) by trying to go Oreo.
The installation went halfway through, but now I can't complete (missing info howto flash bootloader / kernel) and I also can't go back as the partition layout has already changed to oreo style.
Steps done so far:
- unlocked boot loader
- installed twrp
- extract system image and recovery image from oreo update zip
getting the phone in fastboot mode i can successfully run
fastboot flash recovery_ramdisk recovery_ramdisk.img (i can also flash old recoveries this way, but none of them will successfully boot into recovery mode)
fastboot flash system system.img
either way, the system will not boot afterwards.
how do I manually flash bootloader / kernel on the oreo partition layout?
erecovery and hisuite won't recover my phone either...
Any hints appreciated

Can I flash just the stock recovery to my phone and if so is it the recover_ramdis.img, or do I need to flash them all. I'm on mostly stock bnd-l24. Unlocked bootloader TWRP and magisk for root. There's a new update and i wanted to flash stock recovery so I could update.

Will uninstalling magisk fix that or does the boot image have to be reflashed. Thank you for the quick response

FingerPrint and themes not working

I was on nougat on my L21_hw_eu before i tried to upgrade manualy to oreo. i tried the twrp and terminal method and my phone started upgading. It failed at 72% saying "update verification failed". I lost my stock rom and bricked my phone.
Then i manualy flashed different Update.app images and was able to unbrick my phone .
I tried lineage OS and stock oreo.
Problems are:
1: I cant factory reset my phone using stock recovery it fails at 24%
2: FingerPrint Sensor won't work except for gestures (in Stock oreo. works in LineageOs)
3: Themes dont work
4: Flash light don't work
4: CAMERA is not responding. in both roms
in lineageOs everything works perfectly except Camera.
Please provide me details for what am i doing wrong..

If you only have extracted images flashed from update.app, then you do not have the full rom installed.
You should run either hurupdater of HWOTA again to get full emui8 installed.

i flashed different images from UPDATE.APP manually through fastboot and twrp.. I was succesfull and fingerprint was working but camera was still not working so i stupidity flashed DTS.IMG, ODM.img, and ERECOVERY_KERNEL.img through twrp and when i rebooted. there was completely black screen and nothing was working. fastboot only recognizes device and i m able to send commands . i wanted to flash other dts,odm and ERECOVERY_KERNEL.img through fastboot but it says "remote command not allowed". there is absolutely no life in phone. i think it is hard bricked. is there a way to get device back?? or else i m completely F****D.

As far as I know (which is not that far). You need three images to be correct for recovery to load on oreo based device.
1. recovery_ramdisk.img
2. kernel.img
3. recovery_vbmeta
try to flash those in fastboot first. and see if they complete without error.
then if they do flash, try to boot into recovery. (try with stock first-- can try TWRP after if this works)
