Phone won't unlock bootloader without bricking - Sprint LG Optimus G

Ok I've now recovered my phone 3 times after trying to unlock my bootloader, I've done it with freegee and GAIO both when i reboot I just get the LG logo then a black screen and nothing. I've tried with installing a new recovery as well as not doing the recovery install at all. Anyone have an idea why this would be happening?

GAIO doesn't root zv9, or zvb. For those you should be using fiddy root.

Im currently in the same situation. I used to be rooted on Lifeless but last week I had the same situation (LG screen to black screen).
Now, im only on stock rooted JB. I cant unlock bootloader because it wont let me. You should talk yo shelnut on the irc. When i talked to him last week, he said there is a way to unlock but there is a chance of brick with no coming back. I couldnt risk it, so im stuck on stock rom

You both would just use Loki's Locked Imperium. I've been running it and it's pretty nice for people that just can't unlock.

After recovering I was at zv7 so that's when I used gaio, the other times I rooted with fiddly. And I haven't gotten to the point of being able to install a rom. After unlocking the bootloader it doesn't allow me to ever even go to recovery.
Does the locked imperium not need a recovery to install with?

fiddy has a Universal root. Its for all versions. Maybe even run it twice to make sure root is good. Then either try freegee again or use Locked Imperium. For now anyway.
Sent from my LG-LS970 using xda premium

Well I can't use the locked imperium because my phone hasn't got the jellybean update yet . it's partly why I want to root.I used fiddly the first 2 tries to unlock. Do you think doing a bootloader unlock twice might make a difference?

Has anyone figured out a way to force the jb update?

The short and sweet is: Download zvb update,, update to zv9, root, push zvb uodatebto /cache. Hang on, I'll edit this with a link.

can I just download the zvb update and do it from my computer without unlocking?

Sent from my LG-LS970 using xda premium

awesome looks like i just need a rooted zv9 to do this, thanks alot!

Also, you don't have to use rootkeeper. Just use fiddy619 root for everything. So zv9, root using fiddy, push zvb update to /cache, root zvb using fiddy root again. I can't remember if it freezes at 4GLTE screen or not. If so, do this. http://forum.xda-developers.com/showpost.php?p=38887359&postcount=155
edit. You dont need to rename the update either

Worked like a charm! Never had any lockups or anything. Your the man!
Sent from my LG-LS970 using xda premium

I'm curious. Did you run root twice? Or just the once when on JB? I'm assuming you unlocked.
Also, I'll rewrite those steps and put them in my guide. Tomorrow hopefully.
Sent from my LG-LS970 using xda premium

I only ran root once. I haven't tried unlocking yet though at this time as I'm worried about having to unbrick again. If you want me to try for the guide your writing though I would give it a try.

Now I'm scared to update. LOL Na I'll wait for a Jellybean Upgrade.
Has any one tried to install the zip from LG just using recovery yet? Or is it not setup like that. They say you have to use the tool and your PC, but I assume thats for all the "regular" users that don't play mind games with their phones lol.
I would try it right now but I'm at work and need my phone tonight after work so can't risk bricking it tonight lol.

From the research that I have done, it's mixed if you can root it or not. Some say that FreeGee works to root it again, while others say it's not rootable at the moment. I have not confirmed either or yet. I'm waiting to get more information to see if it is rootable with FreeGee or not.
For the best results, to go back, you need to LGNPST back, wait on a released V9 Rom that can be rooted but until then you can use a "Custom V9 Rom" (actually V9 based) until one shows up.

Root and Unlock is confirmed on zvc bin. The update should be no different. Fyi. To be able to install the update, you MUST have be totally stock ROM. Absolutely no changes.
Follow the Root guide. It'll guide you through the process.

I see. Ok, well I rooted and unlocked my bootloader yesterday. Today I received the update and installed it. When the phone rebooted to install the update, it went to TWRP. Then when the update finished, it booted normally. When I say nothing changed, I meant nothing with my software. Everything was left the same, even my notifications. When I tried to boot into the boot loader, it booted normally so I checked if my phone was still rooted and it wasn't. In a previous thread, you said that freegee and root are confirmed working on ZVC, that's what I was referring to because I'm gonna have to reroot and unlock again since the update unrooted and locked the bootloader.

Gotcha.
We have to have all updates before rooting and unlocking.
I can't remember if this is what it did when zvb came out our not. But we also couldn't unlock zvb for a while. So we avoided taking the update.
Anyway root and FreeGee will take care of you again as they do work on zvc.

So ive rooted this fine device with framaroot and.have flashed both twrp and cwm a couple timea as well but cant seem to boot into them.

I'm guessing you're on stock. I've never heard of that.
So you unlocked using FreeGee?
For this phone, TWRP is your best option. Makes me wonder if CWM has caused that error.
You could try installing TWRP thru goomanager.
Or, run FreeGee again, and install with TWRP.
Or you can use teeny bins with LGNPST.

Run freegee to unlock or the secure boot certificate, not matching what it should be (partition sizes/md5 or whatever security they use) will prevent you from going anywhere besides normal boot

Root on 10p update
By reverting back to 10k update using this guide: http://forum.xda-developers.com/showthread.php?t=2302660 and rooting with this guide: http://forum.xda-developers.com/showthread.php?t=2302660. I now have the 10p update with root. Definitely a longer process than other carrier phones I'm sure but definitely possible. After rooting 10k update I went straight into settings and updated without doing any modifications and root stuck. Just wanted to share so others in the same situation know that there is a light at the end of the tunnel! Good luck!
is there a way to manually install the update?
How are any of you able to put your e980 into recovery mode? Mine ends up with the dead android with an exclamation mark over his open chest.
Rooting on 10p literally only took less than 2mins.
