Lg G3 Rooted but cant install TWRP

hey guys
ok so i rooted my lg g3 d855 and i have verified it is rooted with several apps. i tried to install twrp as my recovery and i have tried two methods
1. via ADB shell
2. an app called flashify
both say it has been installed and they reboot my phone and instead of gettin twrp recovery i get a black screen and a green and red flashing LED, i have left it for 10 mins thinking it was installing but nothing. i have to remove the battery to restart and it works fine (minus the twrp)
also i have checked i am using the correct recovery img as my model number is the d855 and the twrp is d855
please help!
also google has not helped
also please dont use big words as they will pass straight over my head
thanks in advance

you sir are lazy
if you did bother to search properly you would know that TWRP has not been ported to work natively with stock Lollipop on LG G3

oh? so i have a rooted lg g3 that i cant put a custom rom on? is there anything i can do?

I did the same thing like OP and now my phone can't boot into recovery or download mode. So I can't flash it with LG flash tool. Is there a way to revert back to stock recovery?

Can you tell me, now I stuck at this waypoint can I do anything? Maybe downgrade to KitKat?

bro check if inside the back cover it is d850 .if it is u have probably bought it for less money so to flash twrp u have to select img of d850 nd flash it using flashify.believe me bro it will work as it for me and u probably may have a problem of no update to lollipop then go for it .sorry for bad English

Facing same problem.
Could somebody help me.

D852 Fido
Hello there
I am new to this forum and to rooting devices and I apologize in advance if I can't even express myself properly.
So, I have D852 from Fido (Quebec) that I really like and want to keep.
Until recently, it had stock MM and everything was fine.
I downgraded to LP 5.0.1 Telus and managed to get it rooted (phone works fine but no data since downgrade).
I then tried to install TWRP and for whatever reason, it doesn't work.
I used ADB, AutoRec, Flashify, TWRP Official App, nothing works.
They all show that the installation is successful but when I try to boot to recovery (Quickboot, ADB, Power&Vol-), all I get is red/blue led flashes then I press Volume Down and the phone boots normally.
I really want to get TWRP on it so I can flash the latest Oreo on it.
Thank you in advance

Would updating to Marshmallow and using MM Autorec help with installing TWRP on the D855? http://turbobit.net/fg6nmu0ujhpo.html

Probably should have started a new thread, this is for D855. For your D852, try Marshmallow Autorec, worked for me: https://mega.nz/#F!rtI1naZT!LJIKUVpv8fYjrvhpykA4_A!2o433RBZ

Hello, I have problems with my phone. I need help almost desperately.
I can't do anything with my phone now. As you probably read, until about two weeks ago I had Fido stock MM on D852.
I managed to downgrade to Telus LP 5.0.1. After the successful downgrade, I was able to root my phone but not to install TWRP.
Now I can't install any KDZ, not even going back to Rogers/Fido MM.
How can I PM you for faster and better communication?
Thank you in advance,

Hello Whatsgoingon,
I can't try MM because the phone doesn't let me flash original Rogers/Fido (D852) KDZ.
I am currently rooted on LP 5.0.1 and I do get OTA upgrade message to MM. Should I upgrade then try your method?
Is there any risk that I will not be able to do it and get stuck with MM without the ability to downgrade to LP or KK again?
I only want root and TWRP to be able to flash custom ROMs.
Thank you,

I can't make any guarantees, but for me it worked.
I had no other option as I was stuck on MM with no kdz/tot for Lollipop or Kit Kat for my D852, so I have no experience downgrading. It worked great for me on MM and I tried everything else to get TWRP on my phone.
This file does not seem to be restricted to a specific carrier and is supposed to work on all D852s, but you can check this thread to see if anyone tried it on a Fido: https://forum.xda-developers.com/lg-g3/general/apk-flash-twrp-autorec-thanks-to-t3081396

KDZ Upgrading enquiry!

Hey! So I am a noob in Lg G4 developing and stuff!
So heres the question, I don't have rooted system or unlocked bootloader, so if I were to Upgrade my G4 H815 from 10D to 20B , what files will I have to flash, like I am downloading the system file , do I also have to flash the modem bootloader Boot , or is the system file enough ?
I am using lg Up to upgrade, so I have no idea what am I doing

All you need in the right kdz file you want to flash and LGUP software on your windows computer.
Thats it...
Good luck.

Yea, I figured it out later, I was downloading the wrong files thanks!

Yes kdz file is the one you need to flash via LGUP since I had a lot of trouble myself with my LG I've become a little bit of an expert. You can pm me if you need any help Cheers

Thank you for link buddy. Was having a hard time finding firmware for this model.

Flashable Zip?
I had an update go awry, and now I can't get it to boot into anything but fastboot or twrp!
Can someone possibly make this into a flashable zip so I can install it via twrp? I'm at a loss. I can't get any of the support tools to recognize it. I can't get into download mode either. It just goes straight to twrp.
I was able to try a factory reset, but as soon as I chose 'yes' and hit the power button the second time I got the device software check error (due to unlocked bootloader) and then it goes right into twrp.
Is there anything I can do?
EDIT: I was able to get into download mode and use the LG FlashTool to get back and running **WHEW**

All are .kdz. You will lose root.

Nice, I needed the kdz to experiment with them, right now Im trying so hard in orden to complete an stable rom for our device and having this files is essential. Thenk you.

I haven,t tried yet, so let me ask you guys: can we jump from the 10c kdz to 10e kdz and viceversa or there is antiroll rules?
Another question, have somebody found the 10b kdz?

But the good thing about t-mobile is that rollback protection is not enabled. As a result, you can use the 10C root method, which is basically by flashing a prerooted 10c image to the tablet, to root tablet with 10e. So you can't have rooted 10e but you can root the 10e with prerooted 10c.
---------- Post added at 08:58 PM ---------- Previous post was at 08:56 PM ----------
Safe to downgrade from 10e to prerooted 10c. Confirmed.

How did you do this? I have the same issue, it just reboots to TWRP. I can get to download mode, but LGUP doesn't recognize my device.

How did you get into download mode? Your problem sound similar to mine. I'm in a bootloop with TWRP installed. I tried wiping all the caches and installing iPioneer via TWRP but nothing seems to work. I even can't turn the device off so I have to un plug the battery. Can you help guide me to the forum posting that you may have used? Thank you. -Steve

What is the difference between the '10c' and 10e' kdz files? I am missing something. I'm looking to flash my tablet back to stock after mistakenly accepting a OTA update (after rooting and TWRP) that sent me into a bootloop.
Thanks in advance. This forum is a life saver.

Is this the latest software version?

I currently have V20a-OPT2-HQ (Marshmallow 6.0) after reverting to stock ROM from this thread.
Is it really the latest version? I though I had V20f or something before. H815 Norwegian.

considering that thread is almost a year old its obvious that that kdz is not the latest anymore, I have V20G on my EUR device.

How can I enable OTA again?

Stock Marshmallow rom needed urgently - H815 20E

My G4 has just gone on me again, just sitting at the boot logo and a flashing blue led. This is the 2nd time in a week and the last time it was due to a corrupt build.prop, which I was able to replace from backup. This time it has just happened randomly and the original build.prop doesn't help.
So if someone can help me out urgently with a stock marshmallow rom for twrp it would be a big help.
Cheers.

theres is softbrick and bootloop. you are aware that G4 can bootloop do to a hadware issue not software.?
maybe you have infamous bootloop. and not a soft brick. but you can try to KDZ does it boot into twrp.? if not then hardware issue.
for kdz search here to flash using LGUP.

Yes, it boots to twrp. Thats the reason I need the 20e zip file and not kdz. I was able to flash a 20d zip last night which then allowed me to flash the 20e kdz. But when I flashed twrp again just now, the same thing has happened again. I'm thinking now that this started happening when I updated twrp to the latest version via the twrp app, and it was only when I had another app crash and reboot my phone two nights ago that it happened for the first time. I'm going to downgrade twrp to an earlier version and see if that makes a difference.

??? you needed the zip to flash KDZ.??? that makes no sense.. then no hardware issue just a soft brick, a software issue. all you had to do was KDZ to latest version. using the refurbished option on LGUP.
then inject twrp and install twrp permanently and then root .
wich twrp are you using.? have you tried this.
the unnoficial beta5.

I was unable to boot my phone so I needed to reflash it. As I only had access to twrp, I had to flash a zip file. I couldn't find a 20e zip so I flashed the next best thing, which was a 20d file. This isn't the correct version for my phone and let me know that each time I booted it. So once I had the phone booted up, I used LGUP to flash the 20e kdz file. My reasoning for this is that I can only flash a kdz file using LGUP, and as I can't boot my phone, I can't use LGUP. So are you telling me I can flash a kdz file from twrp?
Anyway, it appears the latest twrp (twrp-3.0.2-1-h815) was causing the problem. I reverted back to the previous version and I have had no issues so far. I've taken a full nandroid backup to be on the safe side.
Thanks for the advice.

if you boot to twrp then am pretty sure you can enter download mode and use LGUP and KDZ. that was my point. its even better as its the official firmware that will fix any issues..

I couldn't get the phone into download mode. If I had been able to do so it would've made life a lot easier for me. Flashing the zip file and then the kdz was a long winded way to do it but I finally got the desired effect. And I was able to tell that the latest twrp looks to be problematic for the H815 (I've prepared myself for any resulting backlash).

give the one i posted link a try.. is unofficial and at the same thime official..

Just disabling automatic updates in your rom should fix all this. Latest twrp works fine.
