[G2 Q&A, Help & Troubleshooting] mentorman13:
Hi,

I have my G2 for more than two years but I am very noob in relation to flashing and custom roms.

I started reading various threads here in the forum to try to understand the operation before venturing to flashing but still got more questions.

Things like bootstack, bootloader, loki, etc. made me become more confused.

I want to know if can someone guide me to know what to do and what to avoid, what best practices should I follow.

My phone:

- D802

- 5.0.2 Stock

- No root

- No custom recovery

From what I read I have to root, install a custom recovery (TWRP for example), make a backup and then install a custom rom.

But what are the best options to root? What version of TWRP should I install? Can I upgrade to the latest version?

Any help is welcome.

Ps: I read a lot of threads but I think I missed the really noob friendly guide :D

PS2: Sorry for my english.

I have Mokee 6.0 release version on LG G2 D802 32GB.

Recently I pressed the button in notification panel to switch on the torch and nothing happened plus the torch icon disappeared. Also, the camera could not open. Now it says "Can not connect to the camera".

Any torch app says that camera is in use by some other app.

I tried to reboot my phone - and ever since then every boot takes about 20 minutes or even more.

I also tried resetting, wiping cache and data, downgrading to an earlier ROM version, disassembling the phone, reattaching contacts and cleaning the details, but everything stays the same and my phone still boots for about half an hour + camera and torch do not work.

What can you suggest?

Thanks in advance.

trouble flashing cm13

Just updated from cm12 to the lastest snapshot cm13 on my d801. I use twrp. Flash was successful within twrp. When i went to restart the system from twrp, the screen was black (but backlit), if that makes sense. The screen was on, but displaying black. I've tried to hard reset to get it back into recovery mode but can't seem to do it. Everytime I turn it on, I see the lg logo for a fraction of a second, and then it goes to the black screen, with the phone still on. Any ideas?

Thanks for any help in advance, really appreciate it, I'm a complete novice with any of this, so there might be something fundamentally obvious I'm missing, but I never experienced any of these problems upgrading from cm11 to cm12, or within any of the versions of cm12
[G2 Q&A, Help & Troubleshooting] Meandi51:
For my d802 i needed a bootstack to go to from cm 12 to 13. This bootstack (I remember it was daniel Stuart bootstack) contained all necessary stuff to handle cm13 to install.

Do you still can boot into twrp?

Edit:

Reboot bootloader after flashing

https://github.com/danielstuart14/h...lob/LG-CAF/d801/bootstack-d801-CAF-signed.zip

-FAQ-?*

What is bootstacks??*

It's a set of images, that are essential for your device. These hybrid bootstracks use all the images from lollipop, except aboot & laf, that are from kitkat. So, we can have bump working with LP partitions.
[G2 Q&A, Help & Troubleshooting] reeverrb:
Thanks so much. Okay, so I followed your advice, I ended up using adb to flash the bootstacks from twrp (which took me a long time to figure out how to do haha). Then I restarted the bootloader from twrp. Now I'm getting an error message in the top left during boot, when the lg logo is up. It says:

error: boot certification verify

secure booting error!

cause: boot certification verify

I'm haven't been able to get it into twrp yet, I'm not sure if it is possible. It took many tries earlier today before I was able to get into twrp and flash the bootstacks, so maybe its just a matter of persistence. Any ideas as to whats causing this error and how to resolve it?

Thanks for your time and help

Edit: I managed to activate the hard reset button, but the screen that would normally bring me to twrp when i pressed "factory hard reset" looked slightly different in aesthetic, and when I agreed to the factory hard reset, which would normally take me to twrp, took me back to the bootloader, with the same error message
[G2 Q&A, Help & Troubleshooting] Meandi51:
I do do not undertand your acting with adb ? - the bootstack is a twrp flashble zip file.

Anyway, didn`t you redo the complete installation of cm13/gapps after updating the bootloader ?

Weird. But there has to be a way to go ahead, even when you just get into bootlaoder (via fastboot) - but I do not know w/o quering this forum anyway.

Daniel Stuart bootstack changes the procedure to boot into recovery - but I think you manged that (->factory hard reset)

If you are any uncertain about the steps you have to do, I think it s a good idea to discuss here before pushing the button !

Thanks for the detailed guide and for this noob friendly thread.

I am currently on blisspop 6.4 (marshmallow) and before flashing blisspop i flashed hybrid bootstack as instructed by op. Now i want to go back to cloudyg2 3.3 and dont know what to do? So please help me where to find bootstack or baseband or kernel for lg g2 f320l and what steps must be taken to safely flash cloudy. Thanks
[G2 Q&A, Help & Troubleshooting] Sunandroid:
Your only hope is the download mode and returning to stock through this (check OP for guide links). That boot certification error shows up when you use a KK bootloader and an old recovery version respectively a ROM which is not bumped.

[G2 Q&A, Help & Troubleshooting] reeverrb:
I think I mispoke, I meant that I pushed the file to my phone through adb. I flashed the bootstack in twrp from my phone. And I must have misunderstood your comment, I though you meant to reboot into the bootloader before I reinstalled cm13.

[G2 Q&A, Help & Troubleshooting] MusadiqManas:
I had stock 5.0.2 running on my refurbished and rooted LG-G2 D801 along with TWRP 2.6.8.1.

I downloaded:

1) twrp-3.0.2-1-d801-bump-blastagator-signed.zip

2) bootstack-d801-CAF-signed.zip (Latest Hybrid Bootstack for D801)

3) DU_d801_6.0.1_20160710-0805.v10.4-DIRTY-DEEDS.zip AND

4) banks_dynamic_gapps-6.x.x-20160701.zip

Then I rebooted into TWRP recovery and flashed twrp-3.0.2-1-d801-bump-blastagator-signed.zip and then rebooted into new recovery successfully.

Then I wiped System, Data, Dalvik and Cache partitions and flashed bootstack-d801-CAF-signed.zip.

Then I flashed latest DU v10.4 and then the Banks Gapps and then rebooted system and I was getting a bootloop on LG logo.

I rebooted into recovery again manually and wiped everything again and clean-flashed the ROM only and rebooted. It's again showing bootloop.

Am I missing something or did I do anything wrong? Any help would be much appreciated.

PS: Flashed 31/7 CM13 nightly and it didn't give even a bootloop. Only blank screen. Could it be possible that the device isn't D801 although it was running D801 lollipop firmware and showed itself as D801 in 'About Phone' of phone settings? I was able to successfully flash D801 specific TWRP as well.

Regards!

[G2 Q&A, Help & Troubleshooting] Sunandroid:
I don't think it's something different from a D801. Flashing the wrong bootloader would lead to a brick - which wasn't the case. Have you checked the ROM thread to make sure, it's not the ROMs fault? Or maybe in the ROM threads OP there are instructions on flashing the ROM. Also have you doublechecked the md5 sum of the zip or tried to download the zip again?

I believe SuperSU v2. 76 has something to do with it. DU ROM has it built in. I also tried with 31/7 CM13 build along with Gapps and SuperSU and it didn't boot.

Hi guys, I need some guidance regarding refurbished G2. When purchased, its software was showing it as D802 running 4.4.2 and SIM was working fine. During upgrade to 5.0.2 I bricked it. Meanwhile, removing back cover revealed LS980 written on its antenna module. Somehow I've successfully 'refurbished' it with D801 5.0.2 firmware using LGUP. Device wasn't recognizing the SIM though. Then I Got root and TWRP 3.0.2-1 bumped recovery and flashed CM13. Device boots fine but doesn't detects SIM again on CM13.

Could anyone guide me what could be the problem and how to get SIM working now? Or would I need to reflash LS980 4.4.2, apply permanent SIM unlock method and then upgrade to CM13..?

Regards!

I flashed my D802 with 20 kdz, gained root access with ioroot and installed twrp with autorec v2. After that I flashed hybrid bootstack and then exodus 6.0.1 from 06.08.2016, all went fine and root access was still present. Actually I'm on latest exodus build from 11.08.2016 and anyhow lost root access. SuperSu didn't start from the integrated hamburger menu in settings. I reflashed dirty the latest build 4 times but no luck. Also flashed latest SuperSu in twrp but no success. How can I solve this problem?

Edit: updating the host with adaway is still working, but fresh installed apps who are gaining root access won't work.

2nd edit: OMG... just installed SuperSu from playstore and now all is working.

I have a LG G2 on CloudyG3 3.3.

I am evaluating upgrading to Marshmallow. The intended user of this phone will be a user that has little or no technical knowledge, it won't be me anymore.

1) is it a good idea? as far as I understood, I only lose binary camera drivers, so images will be worse than on CloudyG3 (or stock Lollipop)

2) I am confused by the various Marshmallow editions available. Is there a thread to get some directions? are they more or less equivalent? which ones are more stable and which ones more leading edge?

Thanks
[G2 Q&A, Help & Troubleshooting] Sunandroid:
wrong

loki and bump ar both ways to baypass the bootloader (loki for 4.2 and bump for both). There is no way to unlock the bootloader of the G2. The LP BL is neither unlockable nor bypassable.

Why don't you just put stock LP on it? There is no official MM and with stock you will have the least issues.
[G2 Q&A, Help & Troubleshooting] omfal:
Stock doesn't even have the fixes for Stagefright!!
[G2 Q&A, Help & Troubleshooting] MightyHadrian:
Dammit. But if i install bump recovery and hybrid bootstacks, will it be able to install any ROM/kernel (even on LP)?
[G2 Q&A, Help & Troubleshooting] Sunandroid:
Might be true, but 1) it's not sure those fixes are included in any custom ROM and 2) it's not really likely to become a victim through this issue and 3) there are plenty of sms apps which do not autodownload MMS media.

Well the first thing has nothing to do with the second. A Hybrid bootstack just contains a KK bootloader which means it' bypassalble with a bumped ROM. So your ROM needs to be bumped to run.
[G2 Q&A, Help & Troubleshooting] omfal:
Well dorimanx kernel has those fixes and more...

But anyway, even if we don't agree on this :) I am still confused by the various Marshmallow editions available.

Is there a good thread where I can ask infos about them and a rough comparison?

It would be already fine for me to exclude the bleeding edge ones and then I would check the more "stable" ones myself.

Which ones are more "stable"?

Thanks!
[G2 Q&A, Help & Troubleshooting] Sunandroid:
Honestly I'm not quite into what's going on the G2 anymore.

At the first glance PA by galacticstryder might be worth a shot. Also the TeamExodus ROM seems legit. But that's just the impression I have without actually trying it. There are two CM 13 threads.

Personally I dislike CM, but they might be worth a shot too since the tree is well known and many other ROMs are based on it.

As a rule of thumb ROMs with threads with much recent activitiy and lots of views are the best.
[G2 Q&A, Help & Troubleshooting] Art Vanderlay:
I just updated the index and added about 7 new rom threads. If you skip to the last page you'll see all the newest threads which were added this month, and work backwards towards the older ones.
