[Q] NooB!!! what is required to install custom rom? - G2 Q&A, Help & Troubleshooting

I just received LG G2 802, came with 4.4.2 installed. Now I would like to install a custom rom. What are the procedures should I follow? I know there are many threads around but I am getting confused which come first sequentially, i.e. boot loader unlocking, root, custom rom. Can anyone clarify a bit please?

Its pretty easy now.
First root with towel root
Then use autorec to flash recovery
Then you can your ROM

Many thanks
Thats easy steps.

will this work on the verizon vs980? I'm updating to 24a since i bricked it last night. I forgot what root tool I used but I know I used autorec and it messed up my phone.

I know towel root is universal and autorec has a Verizon version. If it messed up your phone, I wouldn't repeat the same thing though, that would be insanity :silly:

I am not a smart man... :silly:
I thought I downloaded the wrong autorec since it didnt have vs980 in it but same thing happened. it installed twrp but destroyed my system partition. LUCKLY I did the smarter thing and made a back up. after some fussing with twrp (making a back up and moving my old back up to the right location) I am back up and running!
:victory:
quick edit: ALWAYS MAKE SURE TO BACK UP AND STORE IT ON YOUR PHONE!

how?
towelroot then autorec. then flash rom zip.

[Q] CM11 Problem.. Help Needed

Hi all,
I am interested in the CM11 ROM. Last night I spent 6hrs trying and failed, epically.
Here is what I did already:
1. Downgraded from 4.4.2 back to factory
2. Successfully rooted
3. Installed ROM Manager
4. Successfully downloaded CM11 and latest GApps
Then when I tried to boot into recovery it kept going to a screen with a little android guy lying on his back with a red triangle!!! I tried six times.
I got frustrated and just updated back to 4.4.2 and have been dealing with it. I am still rooted and have been able to remove my bloatware and other things you need root access for.
Any thoughts or help as to how I can install the CM11 rom?? I am happy running NovaLauncher and using DynamicNotifications to approximate it but really want to try out CM11.
Cheers and thanks!
Lucky there is no way to root on 4.4.2 yet or atleast no Recovery's yet it could be worse you're atleast rooted and it didn't brick your phone

Did you actually try flashing a recovery first? Just installing ROM manager won't install the custom recovery needed to flash ROMs. You have to do that step as well.

No, I didn't. I am super new with android. Had an iphone for a long time. How do I flash a recover? Can I still do it now on 4.4.2 b/c its rooted?
Sorry about the noob questions, everyone is being very helpful!

LG blocked the Loki exploit with 4.4.2 so you can't flash recoveries currently. You'd have to flash back to 4.2.2 to do that. Which if you want custom ROMs now its going to have to be done sooner or later. Which carrier and model number do you have? If you have an international D802 the above post by @zekurosu will work for you, otherwise don't use that one. You're gonna have to find the method for your model number.
My first guess was that you missed the flashing the custom recovery step, which people above me have already helped ya out on. For being new to Android you did fairly well, you just missed that one step.
Good luck!

I have an ATT D800 running 4.4.2. I can't decide whether its worth it to flash back to 4.2.2 to try again. Pretty happy with NovaLauncher + widgetlocke and fairly closely approximates what I am looking for.
For what its worth, I was in 4.2.2 when I tried the first time and failed. I think mackster is right, I didn't flash the custom recovery. I basically flashed back to 4.2.2->rooted->tried to boot into recovery (OVER and OVER) then gave up and upgraded back to 4.4.2.
Thanks for all the help. At least I now have a rooted phone and have been able to do some cool stuff with that. My goal is to get nexus 5 software in an LG G2 body (battery, camera, etc)
@android_nashville There's a way to have the best of both worlds. You can flash back to 4.2.2 (10d preferably) root, flash a custom recovery with Flashify or FreeGee. Both available on the play store. Then actually update to 4.4.2 following this thread http://forum.xda-developers.com/showthread.php?t=2483043. Eventually, if you want to flash custom ROMs you're going to have flash back to 4.2.2 and do this process regardless. The 4.4 aboot image (bootloader) can't be bypassed with Loki. Its been blocked. But some brilliant devs basically found out they can make a hybrid setup, with the 4.2.2 aboot, and everything else 4.4.2. This way you can have the ability to flash custom recovery, kernels and ROMs.

[Q] D80220D Rooted, but can't flash recovery.

Hi,
I have a LG G2 D802 (European version) which is on KOT49i.D80220d. I believe this is the latest firmware released by LG so far. I rooted it today, but now it won't allow me to flash a custom recovery.
Used IOroot25 to root, and it's working.
Tried flashing CWN through ROM Manager, no luck.
Tried TWRP too, but it goes back into the stock recovery.
It just won't allow me to flash a custom recovery. What's more, it seems its not a supported device in FreeGee. PFA the screenshot.
Anyone has a solution?

You need to use AutoRec - the bootloader in KK will not allow Recovery to be flashed.

Good
Should have posted a question in Q and A by the way... future reference.
A few days ago I had the same problem. When I received my LG-D802 last week, I have performed as a first upgrade to 4.4. A mistake I now know. The rooting I finally managed with iroot25. But I did not managed to install a custom recovery. Then I finally came across AUTOREC. So it went quite easily and without problems. Thanks to the developer for this easy to use tool! Great work!

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.

click the link below to check out the procedure for bringing a soft-bricked phone back to a functional stock firmware with bootloader still unlocked, but you will lose twrp and root. read the directions in the link as carefully as possible and you should have a fully working phone with unlocked bootloader, twrp, and systemless root. good luck!

Sprint Galaxy S4 Rooting

I've spent hours searching and I know this is an old phone. Is ther anyway to root the Lollipop and download Jelly Bean (custom or stock) to it? I'm not worried about Warranties. I'm not exactly a newb and I don't like Lollipop at all. I don't mind KitKat, but what I hate is the front facing camera can't be flipped. Dumbest thing ever.

I'm supposedly rooted. I used KingRoot and then switched over yo SuperSU. But I can't seem to get the Rom's to install. This is where I'm probably going wrong. I'm assuming it has to do with the Bootloader.

Ask the right questions if you want the right answer.
You said you're not a newb. So what exactly was the procedure used to to install those ROMs?
Well, you should be using CF-Autoroot, as it's the recommended method to root these devices. That said, unless you have a frankenphone, only AT&T and Verizon models have locked bootloaders. Enter download mode and verify your device's model number please?

I was half asleep and stressed out when I posted this. It's been a couple weeks or longer since I messed with the phone. Damn forums weren't resetting my password. When I mean I'm not a newb I mean I'm not like brand new to this and I know how to research. I guess you could say I'm not THAT stupid. haha
I'mma have to try this again and figure out what path's I kept trying. I'm so spaced out I can't remember hard any of it. Just that I tried to flash a stock and rooted rom with old odin and new odin. Spent 2 days straight messing with it and trying to get around it. But I kept getting blocked. I didn't come across CF-Autoroot. So I'll try that.

Of all the researching I've done (I couldn't login) that one never showed up in my searchs. haha I'll have to give that one a try. It's been a couple weeks or longer. SPH-L720. I had a few Tri-Bands, but it seemed those were limited compared to the standard model.
Update: I went the CF-AutoRoot route and then tried to use Odin to flash stock mk2 rom. Now that I remember it kept failing everytime and then it would corrupt the current rom. I also tried using TWRP and couldn't get it to work properly.
That's a Sprint device, so your bootloader is unlocked.
Here's something you should note: If you want to flash a ROM, of any kind, you don't necessarily have to be rooted.
Stock ROMs require Odin and custom ROMs require a custom recovery. None of them require root.
Your flash to an older version fails most probably due to the fact that you're trying to downgrade the bootloader (Any stock ROM flash also modifies the bootloader and modem partitions).
But your windows, cable, USB port and windows can also be at fault here.

For some reason I kept reading that it was locked or thinking it was locked because of not being able to downgrade.
So that's what I thought and I guess that's what I was trying to get at in my first post. Trying to go from Lollipop 5 to Jelly Bean 4.3 or so. Is it possible to do that whether it's custom or not?
I just hate the Lollipop and the KitKat. My Galaxy S2 had the JB and Power Button took a crap. So I ended up getting a S3 and now been sitting on an S4.
I know it's not the cable or at least it shouldn't be because it works to flash the stock current rom everytime I corrupt it. The computer is like brand new and running Windows 8.1

Downgrading sometimes succeeds. There are also guides on how to downgrade, though there aren't any special procedures. Maybe the bootloader version of the firmware-to-be-flashed matters.
With custom ROMs it's definitely possible, as they do not change the bootloader.

I guess I'm more of a newb with this than I expected. :/ It's been years since I've been on the forums or even tinkered with phones. HTC Touch Pro 2 was the last one I believe. haha
So... With that being said. Custom Roms are typically to the current stock rom, correct? or is it possible to get a Custom Jelly Bean and flash/overwrite it to the Lollipop/current? Since I just tripped wit the Knox Warranty with the CF-AutoRoot. LoL

If you can find some viable download links, then yes, you should be able to flash custom jelly bean ROMs. But you need a custom recovery in order to do that.
The recovery can be flashed with Odin. Or, since you're rooted, you can also flash a recovery by using an app called Flashify.
Odin requires a .tar file and Flashify requires a .img file.
Oh, and you also need the gapps package for the Google Apps. You need a package for that specific android version, so it should be jelly bean gapps.
