[Q] Secure boot, 4.4.2 & recovery - G2 Q&A, Help & Troubleshooting

Hello everybody, i made some search on the forum but i didn't find the answer to my question, so i ask it here.
I'm actually on 4.4.2 stock rom, i'm rooted (it's not a pre-rooted 4.4.2 but i rooted it after with some weirds methods) anyway, i don't have recovery and when i try to access it i get a secure boot error, it's ok because i can boot on the desktop..
I want to know how can i get a 4.4.2 version rooted & with a recovery mode like twrp. Does i need to install a 4.4.2 stock pre-rooted with the recovery mode pre-installed ? If yes, how can i do this ?
I also received an lg update on my phone and at the send of the installations i got this message "Your device seems to be rooted, you can't update it".
Thank your for the help

Once you get the rooted flag while trying a software update the only way to get rid of it is by goofing back yo stock, also now that you have custom recovery if you try to it you will bootloop/soft brick

Hi Guys, I have read some topics about downgrading, but im not fully understanding if this is only for people who is already rooted or if this will work for a non rooted device. In my case i have an At&t Lg G2 not rooted with 4.4.2 kitkat and wanted to revert to 4.2 so i can root and then flash a rooted stock 4.4.2 kitkat. Is it possible to do that, even if i was never rooted? I do understand there's no root for kitkat as of now.
Thanks guys.

LG pc suite will install the latest available rom for your device which will be kitkat as soon as it is available for you. If it says that you have the latest installed, then use 'restore upgrade errors option.' After this it will probably bootloop but, perform a factory reset and everything will then be sorted.

[Q] Download Mode Rooted Status

Hey guys
I have flashed 20B on my phone. Than i noticed that kitkat update has come to my phone. Then i download the kdz and flashed it. The thing is the rooted label is still there. How can i get rid of it? My phone's suffix is A6WTWH. Thanks in advance!

I've noticed this several times. It seems that the red ROOTED text only appears when you root the stock rom, or when you flash a .kdz format rom manually (rooted or not). I am currently running a Germany open rom on my international G2 which is not rooted. Yet still I see the red ROOTED text in download mode. Right now I'm using the firmware recovery option in the official LG Mobile Support Tool to recover to the international stock rom. I hope this is the KitKat rom but I'm not shure...
Maybe you should try to revert to the stock rom downloaded by the LG Mobile Support Tool, and hope It's the KitKat version. If not, maybe use the stock 4.2 and wait for the official release for your specific country.

The download was complete and my phone was restored to stock. It was a suprise that it actually is the KitKat update...
Unfortunately I also still have the red ROOTED text in download mode, while the rom is clean and official. I am sure the thing I said in my previous post applies to Android 4.2 as restoring the same way before KitKat changed the text to UNROOTED in grey. Maybe LG released an update so that once you root or flash a custom rom the rootchecker permanently states ROOTED. Maybe not, could also be some kind of bug in the early KitKat releases.
In your case you would probably end up having a completely stock rom but still having the ROOTED text just like me. I'd say its not worth your time and having to restore all your data and apps, but that's up to you...

I guess if you flash 10f or something the rooted label will be gone. I have read it in somewhere. But idk how can we update our phones to kitkat with no rooted notification
Yesterday I did "Update bootloader" through LG Mobile Support Tool. After that my D802 shows "unrooted".

The V10f version is Android 4.2.2. It's true that when you flash this version there will be no ROOTED notification.
I'll try to update my boot loader as mentioned in the post above this weekend.

Yeah, sorry, that's called "Upgrade recovery" in "Options menu". It seems that it reflashes the ROM and sets root checker to unrooted.
You should wipe and fastory reset before doing upgrade with lg mobile support tool
Reset when you are on custom recovery and after reseted do not power on the phone
Let go to download mode and do the update

Yes there is a way, theres an app you can install called Autorec, this application will automatically set up a Custom Recovery for you to backup your files, here's a Link to get started.

Thanks for the fast reply, well i read this comment on the link you game me, im just curious and also worried that i might brick my phone, cause im a total noob when it comes to these things,
Here's some of the comments i read about D802T
"Please note you cannot install custom recovery in stock KK via any method for the D802T Australian variant and get it to boot. LG has not released kernel source code for Aussie variant, for KK, so Loki exploit does not work. If you want a custom recovery under KK you will have to install a custom ROM with already patched kernel. If you plan to stay on JB 4.2.2, however, you can indeed root and/or install TWRP without hassle on stock."
"u cant use this on the Australian version D802T.
It will soft brick your phone."
Now what should i do? im just very confused.

there is a way to do it. Follow the guide and root kk but before you install autorec, make sure you have a custom rom zip ready to go on your phone sdcard and whilst still in TWRP (dont try to boot into kk yet), simply flash your custom rom, and then the phone will boot normally.

Not booting into recovery

My friend's got a s3 neo and all he wants is cm 12 on his phone. I rooted using towelroot but I can't get into recovery and even if I install any custom recovery the phone boots into download mode saying "Could not do normal boot" bla bla and Qualcomm secure boot enabled and write secured something like that. I think that some qualcomm security is not letting the recovery written in system. AND then when I boot the phone back on and start flashify it says the current installed recovery: Stock recovery.
Help me here guys. I just wanna get into recovery somehow and wipe and get on with lollipop
Was it on 4.4 before updating to cm 12 ?

Nope. It's never updated to 4.4 it's on 4.3
Are you sure you have installed the 4.3 custom recovery? The 4.4.4 version cannot work on 4.3. Make sure you followed this guide not the 4.4.4.

Are there any other lollipop rom than CM12 ?
@Rox @Barbarian-King Guys I DM'ed you both the same thing. Sorry if I'm annoying you but it's kinda urgent and I'm a nexus 5 user. So I installed the cm12 with TWRP for 4.3. and then after installing it boots into the same "could not do normal boot" download mode screen. Thing is He's kinda jerk and wants it back quicly and I know I can flash stock 4.4.4 but my internet is kinda slow. I have Cm11 and CM12 downloaded but no luck with both
Really need help from both of you
