LG Optimus G Root/unlock isues

Hey fellow LG Optimus G users. Late last month I recently purchased the LGOG on Sprint and came here to seek a root guided. I didn't know that LG locks the bootloader on their devices. I came here, found root guides for 4.0.1 ZV9, 4.1.2 ZVB, AIO, Universal root and to be honest, the rooting portion was fairly simple, but its's unlocking/flashing where I have an issue.
I'm on my third phone. The first phone(unaware of it needing an unlock) I rooted and unlocked using the Universal method and tried to flash a ROM and bricked my phone. THe second time I used AIO root/unlock and my phone still messed up. Here I am once again and I really want to have my phone rooted and unlocked correctly so I can flash Paranoid Android(I like the hybrid ability it offers) but I am too skeptical about it now as I don't want to be out of a phone again. As far as Rooting goes, I feel I can just as easily use the universal method and gain root, but with unlocking, what do I have to do if the AIO way isn't correct for 4.1.2 ZVB? I'm not the best at using ADB and commands lines of the sort but if there is an alternative please help me out. Do I need a different tool? Is it availible on Google Play or is it all on PC?

Look over the guides again.
Use fiddy619 Universal root.
Download FreeGee from the Playstore to unlock.

this is exactly what u want. to add to what engine said... if you reboot after freegee and end up stuck at a black screen(quick lg logo then black).. you are softbricked.. BUT THIS IS FIXABLE. so if the "worst" was to happen.. let us know and we'll get you sorted.

Thanks alot guys, I guess I'll give it another go using this method. If the "worst" is to happen, should I just reply back here? Or PM one of you guys?

Either one of us, and either way is fine. Although autoprime is much more knowledgeable than I. (Not open to debate just in case)

Just unlocked my phone(went and bought the app to support shelnutt). Turned off the phone and then boot back up a clean boot, no error messages. I actually face palmed at how simple this turned out to be. Thanks guys :good:, glad to be apart of a helpful community. I'll play around in TWRP for a while to check its feats.
Edit: Now that my phone is rooted AND unlocked, am I able to remove the bloat apps without issue? I believe this caused my phone to have issues the first go round.

Hack and flash away til your hearts content.
Make sure you backup EFS, and make a TWRP backup and save them to your computer in case your SD gets wiped.

Phone not booting up. PL HELP !
Hello guys !
I have done something terrible and phone is not booting up part recovery now.
I had rooted the phone with one-click universal method without any hasstles and then try to reboot into bootloader by pressing VolDown+Power button.
Eventually ended up rebooting in original android recovery. I tried rebooting with option in that but it was not responding.
While trying it out, I mistakenly wiped cache partition.
Now NO MATTER WHAT COMBINATION I TRY, phone doesn't boot up past the recovery.
Please help me sort out this mess. I need to sell the phone.

I wipe my cache partition all the time. I am rooted but still locked (I don't think that will last much longer). Anyways, in the android recovery with jelly bean, I found that you no longer use the power button for selecting or confirming. It's now done using the menu button below your screen (on the right) . At least that's how it works for my phone.

Autoprime,
The "worst" is what happened to me. Can you please help me get out of this situation?

What is your phone doing?
Can you get into recovery?

When I power on the phone I get the LG logo and from there it goes straight to the "fastboot mode" screen, but I can't access the menus. I can also get the backlight screen, but when I connect it to the PC it doesn't recognize the device. I can also access "download mode" on the phone. Please forgive me if I'm not giving a lot of detail. This is my first root ever.

So you can get into fastboot? Did you unlock also? If so, press volume down twice then power. That should get you into recovery.

what engine95 said. Worst case, LGNPST back to stock, and try again. there is a modified ZVB bin floating around that makes you unlocked, and once you boot into recovery, will root you. its the easiest root/unlock ive ever seen. good luck!
remember, the IRC channel is FULL of great help.

i just followed the steps and now im on lg screen computer not reading the phone and cant get in to fastboot or recovery?

Did you use Fiddy69 root method followed by installing FreeGee from the Play Store? If not you can try LGNPST to stock. Or just take it back for an exchange

ive had 4 softbricks today from trying various things...one involved 20 mins of panicked button pushing. keep both volume buttons held down and press the power button for long periods of time then waiting a min or so to see if it comes up to download. Hopefully you will eventually time it right and see the blessed download screen...from there get teenybin's bin file for whatever version you have and use that...its a godsend

Unlocked Bootloader for 10.3

Will there eventually be an app for unlocking the bootloader on the 10.3 firmware? I don't have the factory cable and it sounds like a lot of people have bricked their device doing the downgrade to 10.2.

I hope so. I am not gonna even try it... Lol instead rooted it and used Kindlefree app to install Nova and used titanium backup. So it's "like" Android but not quite lol....

It worked for me even with the 10.3.1 bootloader. It seems that the exploit is not closed yet.

I can confirm that the utilities still work fine with the latest version of the kindle software, so you shouldn't even need to downgrade.

But if I downgrade my bootloader I won't have to use the whole 2nd bootloader method and all that right? Won't I then just be able to use some utility to flash TWRP and then flash a ROM? This Kindle thing is probably a little more intimidating than anything else I've messed with. I have mine rooted and a bunch of other hacks but I want pure Android on. I don't want a brick though..

What about all that craziness I have been reading about locking up the bootloader due to the 10.3.1 bootloader? I can just forget about that and install that apk file and THEN I would be able to flash a ROM via TWRP? I thought that the thread said that this tool said it was for the old bootloader. This is great news! Can you confirm this? Are we on the same page?

Well, i personally use the aosp Rom by hashcode. It`s simple, nice and clean. But what you are using is your own choice. Flash different Roms and make your own mind.

So, it looks like I have screwed something up. This figures as my luck is terrible with this freegin Kindle. So I got TWRP recovery working fine. I DL Cyanogenmod 10.1 and Gapps accordingly. Went into TWRP of course made a backup, then went to flash. I wiped EVERYTHING and went to flash the ROM. I received the error <Could Not Open .zip> So now I have nothing on file except a bad .zip. I did re-download the ROM assuming it was bad and restored my TWRP backup. Now I am stuck in what appears to be a Kindle Bootloop. The Kindle Fire (Orange) logo comes up, a few seconds later it blinks back off again and recycles. Now what? I can't get the Kindle to boot so I can put the .zip back on the machine. I am STUCK. This sucks... :crying:

I did the exact same thing when i got my kindle back in January. (Yeah, i had to order my cable right after that )
For some reason I've never been able to restore a stock TWRP backup on the kf2. It always borks the bootloader.
I know there is a special requirement that our bootloader uses a file called stack on the system partition- that's why you can't get into recovery now (when you wiped the system it wiped the stack file which let's us run the second bootloader.)
Anyway, Once you have the fastboot cable its really easy to get things going again. Pm me if you need a hand.. I've been through this myself a few times lol.
If you ever end up in the same situation again where you wiped the system and the zip is bad... Stay in twrp and use "adb sideload" to push a good zip from pc.

I actually tried the side load through TWRP. When I typed "adb devices" it showed my device in host mode and the file wouldn't transfer although TWRP was in adb sideload mode. But then I just thought "oh well guess I'll restore my backup" lol. Yeah that didn't work out..

Thanks for the info guys. I'm glad I didn't have to change the firmware. The whole process was super easy and now I'm running jb 4.2. For those reading, just root->install one touch apk->make backup in twrp->factory reset->flash rom and gapps->success!

**As a special note however DO NOT restore your factory backup if you have trouble. You will end up like me. Bootlooping with a fast boot cable in the mail.** if I could go back in time I would've downloaded the files via a hard line rather than slow wifi and maybe even double downloaded.. Oh well.

I don't think that root is for this phone. As for the recovery... It's for the Pro. This is just the plan ol' Optimus G.
If you have the Optimus G, use LGPST to fix your recovery. I think that's your only option.

[Q] Does anyone have a clean, stock nandroid backup?

I was trying to get apps to sdcard working and I managed to foul something up. I know I should have made a backup first, but I thought I only made a change to platform.xml. Thanks in advance.

Anybody? Please? If you're installing a new ROM, you have to do a wipe user data/factory reset anyway. If you could make a backup from there, it would be greatly appreciated.

It looked a little sketchy. So I'm not surprised that I'm stuck in a bootloop now. I thought for certain someone had 3 minutes or so to spare while switching ROMs to make a backup. I'd spend five minutes of my time to save you an hour and a half of aggravation. And I'm no saint.

I'd make one except I have a gpe tab and I'm assuming u have the standard LG edition.

Using the R&D Test tool, I can get my tablet into a bootloop where I can execute adb commands. I just haven't figured out what I need to do. I can't reboot into recovery or bootloader.

Holy crap. I finally got somewhere. CWM and CM11 installed. So I can use my tablet again. I'd still like a stock ROM tho. Pretty please?

I had the recovery I was using from MM but I also completely wiped then installed 7.0 in Odin. Only difference I rooted before trying twrp, maybe that effected it. I'll keep playing with it I'm sure I'll figure it out. I was just curious if you needed a custom kernel. Thanks again for the help and link to root.
