LG G4 815 won't load in twrp recovery - G4 Q&A, Help & Troubleshooting

Hello! Got some trouble booting my phone in recovery mode. As a first step to install new firmware (linageos) I flashed latest TWRP via official app and it said recovery flashed successfully. Next, I tried to boot recovery to flash new v29 bootloader but phone does not react to hardware key combination (tried many times) and just boots the system. Ok, I installed Quick Boot app, it does some job - phone reboots, about 10 lines of text appear on screen and that's it. Last line says in red - fastboot mode started. Any thoughts how to fix this? Thanks!
Phone model LG G4 H-815, Android 5.1, rooted, bootloader is from official unlock.

You have LP. newer official TWRP builds does not support lollipop anymore.
In the official TWRP thread you can find a link in the download section to my PREVIEW builds. You will need the MM flavor to boot on your firmware.
Once you have flashed the v29 bootloader you can use the official TWRP again

When you flash the recovery.IMG , the file has to be saved on your computer and phone.

i can now type in adb reboot recovery and TWRP works!
now, my next problem is.. how do you do the button command when powered off to go to TWRP? the usual recovery buttons still go to the stock ones (where you factory reset everything)

Zenfone Selfie Marshmallow Bootloader Unlock (NEED HELP)

Hello,
I have recently updated my phone to marshmallow complete stock, then I flashed pre rooted marshmallow system.img and boot files through fastboot and twrp.img too, but I cant get into TWRP, even tho If I flash stock recovery, i can go into it. So I flashed stock recovery and running prerooted marshmallow, It seems that I've to unlock the bootloader in able to get into TWRP custom recovery. I want to use a custom rom like XOSP or CM there available. I tried the unlock bootloader app provided by ASUS but that seems to only work for ollipop. Is it really about bootloader should be unlocked in able to get into TWRP? I cant get into TWRP, ASUS logo appears and If I continue pressing power+volume down it will just hold on to that screen and restart.
Please Help!!!
This happens with me too ..
any help ?

Cant get ROM to boot.

I tried upgrading to 7.1, and have tried 3 different ROM's. I even tried going back to 6. Every single ROM told me error code 7 when I tried to flash it. I went about fixing that. So then I was able to flash the ROM and GApps. But then when it goes to boot into the OS all it does is hang on the white Asus screen, reboot, and go back to the white Asus screen. It does that 3 times then goes into recovery. I even tried fixing it with ZE551ML_Modder V3.3. I am running TWRP-3.0.2-0-Z00A.img. This is a Z00A as well. Any help would be greatly appreciated. Thank you.

Did you upgraded the bootloader? I would just retrace steps, if not factory reset and try again.

The bootloader is the recovery right? (At least thats what I always thought). If so then I am running the newest TWRP for it.

Upgrade your bootloader following the instructions on the .zip package.
This will upgrade your bootloader and flash a compatible TWRP recovery.

I did all that. Now I am stuck with CM Recovery. I tried using the tool to get TWRP back but its not working. I have to figure out how to push TWRP using ADB.
In modder, return to stock option , flash stock recovery and boot img.
Unlock bootloader in modder, just incase.
Flash twrp, root in modder ..reboot to twrp...install 7.1 and pico gapps
I finally had to go to Ubuntu, run ADB as SU and ADB Sideload an older version of Cyanogenmod. Not a single factory image would work. And not a single one of those Android 7 ROM's would work. They are all broken. I would like to see real proof of one working. That little escapade cost me a lot of time. So until someone comes out with a real CM14 version for the Z00A do not attempt to boot one.

You may have really misunderstood the processes and yes they are allover the place.
i am running CM14.1 lots of people are !
What you probobaly have is LP based CM 13 on WW-4.20 blah blah.165
Then there was a CM13 with MM blobs based on WW-4.21 blah blah .135 MM
I think where you have gone wrong is not unlocking bootloader in 5 LP and upgrading bootloader and unlocking.
if you are on .165 - you could flash stock recovery for .165 -- upgrade to .184 -- unlock bootloader and upgrade to MM then unlock bootloader in MM with modder
Then use the modder to install 7.1 14.1 CM
But judging by the probs you have haD already - just leave it alone :good:
What is WW?

You know what you are doing re using ubuntu to adb but have the procedure all messed up.
Would you like to get to MM and 7.1 CM14.1 and have a windows PC ? ?

How are you relocking the bootloader? . As far as I know that is not possible.

re locking bootloader is possible. flash raw firmware. or flashing boot, recovery, fastboot and ifwi images.
@DarkshadoW99 very first of all you started new thread without searching around. and if you started a new thread your post is too confusing or lacking the context of your post. unable to understand what you actually want.
very first of all while unlocking bootloader with unofficial method. you may get error " failed too many links" but even though bootloader is unlocked pretty well.. ( mention which tool you are using to unlock bootloader)
second thing is you stated that you are trying to unlock bootloader to access recovery. what does it actually mean? do you want to flash custom recovery or your are unable to enter recovery mode?
"in marshmallow if you boot with unlocked bootloader the phone stuck on asus logo" what does this line means? are you stuck at asus logo? as far as i know you can boot in MM with unlocked bootloader too. unable to understand what you wanted to say.

Since there isn't any OFFICIAL unlocker for Zenfone 2 Marshamallow, your best bet is to go back to Lollipop abd having an unlocked bootloader but again, it'll be without Marshmallow:
Download official firmware latest release or whatever you had BEFORE installing LineageOS. Rename the the file you just downloaded to:
MOFD_SDUPDATE.zip
Click to expand...
Click to collapse
and put it on an SD-Card, put the sd card in your phone, boot into recovery (by booting to fastboot and selecting recovery) and the restore should start automatically.
Now at this point you'd be back to stock marshmallow and you can downgrade back to Lollipop ( V52.20.40.197--be mindful the link is for the JP SKU and you need to download the right SKU version for your phone in case you have WW --didnt see you specify or not, so maybe you want to check you downloaded the right Lineage OS as well as maybe thas why its freezing ) to use Asus' Unlocker.apk [You can find instructions on official Asus website under support]

If the last thing he installed was LinOS then he has twrp for recovery. I don't think that method will work.

That's a very valid point, but since his post is vague and quite confusing, unless Lineage has a function within the ROM to "relock the bootloader" I would've assumed he "relocked the bootloader" by installing/fastboot flashing some official boot.img and since he cant get into recovery and his bootloader is locked, I had imagined he'd be back to stock fastboot.
but meh, my guess is as good as any. Unless the OP adds some clarity, we can at least say we tried, amirite?

How to get root on Nougat

Hi folks ! i have read a lot but getting confused somehow. Can anyone tell me or guide how to root my HTC 10 on Nougat ?
Unlock bootloader
Flash latest TWRP
Flash latest SuperSU
Beware Unlocking bootloader resets phone
Make sure to Nandroid backup
Better would be to flash Magisk to obtain systemless MagiskSU. This will keep SafetyNet working which is needed for Apps like Android Pay and so on to run and work. On the other hand you can in addition install some miss without even modifying system which would enable you to just flash stick recovery and install official OTAs as soon as they hit.

Bootloader needs to be unlocked. TWRP is compatible to Nougat - see TWRP thread. Latest Magisk can be found in the Magisk forum. Yes you can flash mods and install root Apps if you flash Magisk as it will flash MagiskSU as well.
All can be found in the respective threads, named above.

Flashed latest TWRP, but it won't boot into TWRP. Tried about 15 different TWRP versions, no luck. Any ideas?

Detail your steps, please. Exactly what TWRP version are you trying to flash, and where did you get the TWRP (link to it)? Did you check the MD5 hash of the TWRP you flashed? https://twrp.me/, besides supplying all the official versions of TWRP for the HTC 10 "pme", also gives a link to the MD5 hash of each version in small print on the Download page for the version you choose "md5 for twrp-3.2.1-2-pme.img".
How are you trying to get into TWRP once you flash it? On the 10, after holding the Volume Down and Power buttons to boot into Download mode, choose "reboot to bootloader", then from the bootloader choose "boot to recovery mode".
I haven't been on Nougat since 8.0 came out so I can't personally test the latest TWRP with it, but if there's any problem with the latest versions with Nougat I'm sure it'd be mentioned in the TWRP thread here in the HTC 10 Development section. Have you asked about this issue there?

Hey, thanks for the quick reply mate.
Bootloader unlocked through the HTCDev site instructions. DL mode shows device unlocked, software modified, and S-On. SD Card is inserted. Fastboot in download mode to flash every .img listed on twrp and all .img files from the unofficial list. Didn't check the MD5's, thought it was pretty unlikely that all failed, but I'll try that when I'm out of work. Attempting to flash from Download Mode, using "fastboot flash recovery twrp***.img", *** changing per version. From bootloader mode, when I choose "Boot to recovery mode", I get the HTC logo + red disclaimer, then a reboot, more HTC logo + red disclaimer, then back into bootloader mode. Google searches have suggested using unofficial TWRP 3.0.3-6 or 3.0.3-9, but these files are nowhere to be found anymore. DL links here on xda seem to have been removed. 3.0.3-10 and -11 produce the same error as all other .img files. I've tried this on a machine at home and a machine at my job, so that's two different networks as well.
As a secondary, I've also tried "fastboot erase recovery" a few times before flashing TWRP images, same result.
Edit (2/3/18 @ 16:01): Verified the MD5 hashes, everything has downloaded correctly. Even if anyone has a copy of the 3.0.3-6 or -9 .img files, I'd be willing to try those out too.
