[Q] Bootloader, CWM & Rom help - LG Optimus G Pro

I have managed to root my device after the 10P firmware! FYI, I used Android Kingo Root.
After looking into many posts, forums, etc... I have come to the conclusion that unlocking the bootloader is going to be trickier than any other device I have been successful with. I want to install CM 10.2 and CWM 6+, however, I cannot find solid information on how to unlock the bootloader for this unit. I would have liked to install the latest 4.4.2 from AT&T, but the device was rooted prior and AT&T will not honor the phone for the upgrade. At this point, I feel it would be easier to just install a custom ROM instead of trying to put the AT&T stock back into the unit.
Most of the info I see seems overly tricky and doubtful. I have downloaded FreeGee, but, in version 1.9.23 there isn't an option for unlock or disable security,(I have emailed the devs for the app). I also have gprorecovery.apk, but, I am deathly afraid to use it as I cannot find ANY material about it anywhere and I am worried to brick the one phone I absolutely love.
If someone has the knowledge, please share. Also, feel free to add in your experience and pitfalls with this device after manipulating the software. I am not 100% sold on CM, so if you want to suggest a great ROM...Feel free.
I appreciate the help and suggestions in advance.

No unlocked bootloader for the gpro. Sorry dude.

There has to be a way to install a custom recovery and ROM. I asked that if anyone replies,to elaborate. Please explain...

With freegee first backup efs, then install twrp or cwm.

And then reboot to recovery as normal to install the ROM? I have read so much information that states you have to do some special presses of the buttons to get recovery to load. What are you running on yours?

Once you install recovery press power + volume up (asuming you powered down or resetted your device of course) until the lg logo appears ( some white letters will appear on the top left corner, release power button when they do). That will take you to the recovery. I'm. Using a cwm/twrp combo. I flash everything i need with cwm, twrp i keep since this phone has a tendency of going into a recovery bootloop and only twrp can get you out of it. Always keep your flashing files on the internal storage, sometimes flashing from sd card wont work.

IMEI is 0 -- ODIN restore?

Sadly, it seems my IMEI has been set to zero.
I can still make calls and text, but my data is on Edge network only.
I've been doing some searching and reading (by some I mean a lot) and I guess I'm getting a little confused in it all.
Would using ODIN to reset my phone to stock fix the IMEI?
I have the IMEI on a sticker on the phone, could TMobile reset the IMEI for me?
Thanks in advance.
Swap it if you have insurance. If not search xda for fix.

Yes Odin will fix the Issue. Please choose correct firmware to flash via Odin.
Thanks for the response.
Trying to confirm I get the RIGHT rom for my device.
Went to sammobile.com/firmwares/
Looking at all the options for SGH-T999, do I have to made basebands to what I have now (T999UVDLJA) which is dated Oct 2012, or is that something that gets "updated" if I apply the latest rom (March 2014)?
Depends on what you had before all these problems. You must choose that same version otherwise you may hard brick the phone.
*sigh*
And I suppose there's no way to know that? I don't have a back up or anything...
Is there anyway to determine?
Thanks for your help and direction thus far!
Oh Sure. There are other ways to determine. If possible post a photo of the download screen. Otherwise type out exactly what you see when the phone is in download mode.

I'm assuming that is the info you were looking for?
Yes that's what I needed. I suggest please use UVDMD5 Version of Root66 to flash via Odin.
Excellent.
So follow directions and get files from here?: http://www.androidayos.com/2013/05/...y-bean-without-binary-flash-counter-increase/
Well. Yes. I'd direct you to the Thread here under Android Development.
Yeap. The link I posted actually takes you back to the link you provided.
Both bookmarked.
I hope to do this tonight.
If I understand this correctly, this should flash my phone back to stock with my valid IMEI
Using this Route66 I will have root on the phone and should then be able to do a CM install if I choose?
Yes and yes.
If that is your desire, then while you are in Odin, flash a custom Recovery such as TWRP or CWM as well.

... I will have to research on how to do that too then.
First concern is getting the IMEI back so that I can actually USE the phone with data -- regardless if it's CM or stock OS.
As the UVDMD5 will have correct modem, hopefully that will restore IMEI. Otherwise we may have to see what happens.
hmmm sort of seems to have worked... stuck at the "SAMSUNG" screen though.
Reading other links says I should have cleared cache before doing?
Hmmm cleared cache.
Did factory reset.
Still stuck at pulsating "SAMSUNG" logo...
Ok got into phone... ugh is stock ROM just painful. Who designs these things?!?!
Sadly, IMEI is still set at 0
this doesn't seem to have worked

ARGGGHHHH Are you serious? Googling now, but this looks much more complicated compares to Odin
Can't TMobile just restore the IMEI if I take it to one of their stores?

Okay, you are most likely still stock kernel with recovery installed. Rooted no problem.
Recovery will break knock code unless you flash another kernel that has it.
Before doing anything, know that nobody really has a custom zvd Rom out right now. Artifesto put out a stock version.
You can easily go back to zvc which you lose knock code, art, and hd calling.
Super g2 Rom is fantastic and you can even go with their full Rom or bare back ( slimmed version)
To get recovery which will put a older kernel on it. Easiest way is to use auto-rec from

Read the first couple posts. Before running it and ask what you want from me.
This gets recovery running and fixes download mode. (Vital if something bad happens)
Please ask anything before doing something if not sure.

The only thing I am really wanting to do is bypass the wifi hotspot on the phone since Sprint has a block on it. Wasn't sure, I thought I read somewhere that there is a modication I can install to do that, but I didn't want to do it without talking with you first. Am I right there is one that would just be put the zip file on the phone? Then there were other steps but that is really what I am trying to get done so I can use it as a WIFI hotspot to pair with my tablet.
Yes it is included with super g2

Cant flash TWRP

Hey guys I'm kinda new to Android I've had a chappy phone and now an LG g pad after attempting root about a dozen times I finally managed to get it root now I am trying to get TWRP to backup the tablet and change the boot animation later but every time I tried on my pc it would fail so I installed flashify and tried with that I then I got a boot error saying security issues. The tablet stills boots but I believe the problem is the locked boot loader. Thanks for any help offered.

Have you installed root checker or another program to confirm that you do, in fact, have root? Start with that.
If you haven't installed a superuser app to handle permissions, I'd do that as well before trying to install TWRP.
I'll admit I had troubles installing TWRP as well, when looking at the forums, make sure you're downloading the version for your EXACT version of android and firmware, and following the instructions for the right version as well. Good luck!

YES, IT WORKS.
After this procedure, just update your Recovery (CWM or TWRP), using Flashify, available in PlayStore.
Thank you!
Did you use freegee to install cwm or twrp?

Hello, guitarboy21. Yes, I used FreeGee to install TWRP (version 2.6.3.6, something like that), ant then updated it to the TWRP 2.8.1.0 modded version using Flashify. And all worked out ok.
But first, before doing like explained here, I tried using LGOG Pro Recovery + TWRP using Flashify, and it softbricked my phone. So I unbricked it flashing the Stock 4.4 KitKat KDZ and did the procedure following the steps in this topic.
Gladly, now I think it's all good.
Thank you for your help!
Hey man! Congrats! Sorry it bricked your phone but its nice to hear that it worked. If you had flashed using freegee directly it wouldve bricked ur phone. Anyway, hows the experience? Is everything working good?
Do you have the option to disable capacitive keys and enable softkeys? I can help if ud like it.

Does this work on E98820b-MYS-XX with build number KOT49I.E98820b ?
When I reboot into recovery, it still shows:
Fastboot mode
udc_start()

This worked for me when nothing else would. Many thanks! I now have CWM Recovery where I had NOTHING before! :good: :good:
It isn't really an unlock. It is more of a boot certification bypass.
GASP!!

I can't believe I've found a custom recovery that actually...lol...backs up stuff. Other than the absence of Loki-fying Kitkat, this is not bad.:good:
This tutorial saved me a ton of headaches. Thanks so much.
It is work for me,too.Thanks.
got it working on 4.4, 20a ROM
thanks
Wow this actually worked when all other methods failed, thanks so much
Thank you so much!
This tutorial helped me to get out of the "Secure Booting Error! Cause: boot certification verify" error when try to boot recovery in a LG G Pro E989.

Rooting

So...I'm no longer under warranty thru Sprint, but still have hardware coverage. So my Sprint store said in not so many words that playing with my software is a go.
So I haven't done a root since my lg2 so I'm way out of the loop. I've been reading thru the forums here but all confusing and not very organized.

First off, you need Odin. It's a must, can't do anything without it.
Next you need to download TWRP custom recovery (Team Win Recovery Project) and use Odin to flash it.
From there, go into twrp on your phone and flash superuser to root your phone. OR if you're going for a rom, make a backup, go to wipe, advanced wipe, and select dalvik, system, data, and cache, perform a wipe, then flash the rom you choose. Most roms come prerooted anyway so you won't need to manually flash for root.
Hope this helps.
