Maybe someone here will be able to give you specific instructions, but you are probably better off asking your question HERE. You have a Sprint phone, and this forum is for international models.

Did you read my post above? You are in the wrong forum. Ask for help in the LS970 forum, and follow up on the answers you are getting already. I saw your post in the LS970 forum, and you were pointed to the TeenyBin solution. This will only get you halfway there (it's the tool typically used to "unbrick" your phone), and you still need to flash the ROM of your choice afterwards. Flashing the full stock firmware would probably be a better solution for you, but the tools and the processes for Sprint LS970 are different from international versions of Optimus G.

[Q] Running out of ideas...

Hey guys.
I'm desperate for some help with my LG G PAD 8.3 tablet.
All i simply want to do is put cyanogen mod ROM on the device, and I can't believe how difficult it is proving to do.
I have been all over the internet and spent around 4 days researching in to the whole process and every time I follow various online steps, guides and you tube videos i end up putting the tablet in to a software brick and then have to use the LG recovery tool to get the tablet working again. It's driving me insane!
So first of all i rooted the tablet using towel root. I then get a message saying that the device is rooted. I then download the super su app and that goes fine. I then try to get TWRP or CWM on to the device so i can back up the current running operating system and it's down hill from this point. The device reboots and comes up with:
Secure booting Error!
Cause : boot certification verify
it's happened 4 times to me now. I just can't figure out how to get this device doing what I want it to do. I see loads of videos and success stories of people having no problems getting cyanogen mod on to the LG tablet so what do i do? Is there someone that can provide a detailed step by step instruction to get this right?
i'm at the point of just giving up on it and being stuck with a poxy horrible LG stock look.
PLEASE SOMEONE HELP!

Anyone???

If I missed it in your OP, remind me, but what variant model of the 8.3? VK810.4G? V500? V510?
Sent from my VK810 4G

Sorry. Yes it's the v500 variant. I really wanted get this sorted and will appreciate everyone's help.

F460 owners soution for unbrick
F460 OWNERS . WE HAVE EASY HARD BRICK METHOD.
com port 9006 can be fixed. google partition unbrick. ubuntu method also works.
f460 : 9008 com port,, no twrp, no download mode, boot security error, verification failed. traditional lg flashtool, board diag, lg smart boot doesn;t help at all., i tried all and fed up. finally understood only 2 options on our own solutions available.
1. dump file using sd card
2. BOx method like riff, jtag, .octoplus (Risky as it shorts resistors may phone dead)
3. debrick image create ,
we our selves has to wake up and try to build by 1 and 3. 2nd option is expensive, soldering to emmc is not advisable.
for option 1, vietanmese selling dump filess, if anyone bought dumpfiles for f460, kindly upload and share with us.
option 2 by professionals repair method, option 3 debrick not yet availble for us, seniors has to look into this to create it. debrick is easy and simple and best of all.
ANY ONE HAVE DUMP FILE OR DEBRICK IMAGE FOR F460? thanks me if usefuL

LG G4 help needed!

I have the lg g4 h815 international model. It is rooted and has the boot loader unlocked, I manually upgraded to android 6.0 and then a few weeks or months after I was just on a normal day. So I turned my phone off, then when I needed to turn it back on it failed to start up only showing the lg logo with the boot loader unlocked sign in the top left. I tried all that I knew how to. I went into TWRP recovery and wiped all the data from it. I tried to boot up but it would not and it said that I have no OS installed, however I was sure I did. So }I tried the kdz method of restoring my phone but the lg flash tool 2014 seemed to not respond instantly.
Next I tried downloading the stock files and stock ROM and tried to flash them, but when I attempted to flash them using TWRP it froze and went back to the LG logo screen with the boot loader sign in the top left and it wont let me do anything. I can still go into download mode and recovery though. I have tried every method I know of and I am really stuck. If someone knows how to fix it then please reply, thank you.

If anyone knows how to fix it then please reply, thank you.

When u wiped u prob wiped all download a custom rom and put it on sd card the in twrp install it should be good to go

Thank you for responding
I tried this but when I attempt this, TWRP freezes and it takes me back to the LG logo with the boot loader unlocked sign. Because it keeps freezing I cannot restore a backup or download a custom ROM and I am stuck on what to do.
EDIT: Also when trying to use the kdz method the lg flash tool 2014 just fails and force closes.

By chance u aint got the 505 serial number device do u there was a sorta recal on a few devicez if im not mistaken and im actually new to this device but i had g3 and it was a common problem on g3 for bat to go bad try dl rom and installing it while plugged in to power source other than that im not fortunate enough to have bl unlock and twrp or i might be able to give some more assistance

You can try method which mentioned here:
http://forum.xda-developers.com/g4/help/lg-g4-stuck-bootloop-t3268734/page25
Read two last pages.

[CLOSED][ANY BL locked G4]need testers [follow the new thread!]

First of all: Do not continue if you don't know what a hard brick is!!!
so well its that simple: Either my method will work or fail.
Please follow the story here now:
https://forum.xda-developers.com/g4/general/bl-unlock-unlock-bootloader-proof-t3648288
Previously this was the OP:
if not: this could result in a completely unusable device (soft or even hard bricks are possible)
If it works: you could unlock your phone in fastboot with a simple command - no unlock key is required (but even when the method WORKS its possible that this produces other issues. we can not know all impacts yet)
So AGAIN
The whole process is dangerous but the chance to get an unlocked phone would be worth it - maybe. It depends on you.
I can't test it atm by myself because my device is on its way to LG (due to another issue)..
My method does not modify something within the bootloader like others tried already - because this would definitively break the boot chain.
I will not release any details to the public until there is anything proofed or verified. The whole process is very risky and as said: I have currently no device to test it.
The only thing which is proofed is the theory. It should work as long as nothing unpredictable happens: As long as we do not own the complete sources of all parts of the boot chain there is still a risk.
Keeping the details under the hood is not to make things mysterious. It's just for safety reasons until I can proof anything.
If you still ask for details here or by PM they will not be answered.
If you not able to join an IRC channel you better leave it directly.
I'm not 24/7 online but usually from Mo-Fr for sure so it is important to wait for answers while in the IRC because depending on your timezone this can take some hours (hey I have to sleep somewhen!)
Once I have my device back from LG I can test the method by myself on a H815 EUR version. It doesn't matters that this can be officially unlocked though. The risks are the same.
So if you're too scared for the moment just wait about 2 weeks or so and then I can tell if it worked on my device at least.
.... and if you do not want to wait: Follow me into the IRC for instructions
If you never were in touch with IRC before here are some client examples for you:
PC (HexChat and Pidgin are only 2 of them! This list is not complete!)
Android (Yaaic, AndChat, HoloIRC, AndroIRC are only a few of them! This list is not complete!)
The IRC channel is: #Carbon-user
The IRC server network is: freenode
Once you're connected with the IRC network I need this from you:
your phone model
the currently installed EXACT firmware (link to the used KDZ would be most helpful. If you have none check the phone details and e.g. make screenshots)
.

Super excited about the possible G4 unlock! Wish I could test it but my phone is my daily driver and my source of internet at home so if it breaks, I'm screwed for my online classes. Thanks for your hard work as always!

It happened to mine 818p too, you need to disasseble it and short two pins on the motherboard while starting it. (They are in the upper left corner on the MB.) This page (forum.gsmhosting.com/vbb/f779/unbrick-lg-g4-brick-hs-usb-qdloader-9008-without-box-2211744/) has the entire process explained but I was unable to sucessfully use the QFIL app, it didnt recover anything, at least the phone was seen on PC as the 9008 serial port. I hope it helps
P.S: Sorry for my bad english.

i hope you get it going man. so lots of users can enjoy this device like it should be.. youll be saving LG G4.. am glad that what i mentioned you got your brain thinking and finding ways i beleive this all was what i mention on fish. good luck to all of you.:fingers-crossed:

The IRC server network is: freenode
Once you're connected with the IRC network I need this from you:
your phone model
the currently installed EXACT firmware (link to the used KDZ would be most helpful. If you have none check the phone details and e.g. make screenshots)

Now out of curiosity would a bootlooped g4 work. Most of em boot into dl mode and if it bricks dl modde youd know rite away anyways right?

Hi, I have the model H815T but... now it Hard Bricked haha. Anyway, I can boot it like LS991 model (with QFIL), and Download Mode it's working too. So... is useful for your method?

Qcom 9008 mode? It could be fixed afaik.. You can also try the sdcard boot method for this kind of brick. you should try that first in any case..
I'm not sure if my method will work in that kind of brick mode you are in but if you nevertheless want to test you need Linux / best is using FWUL because it has everything needed inside.
Once ready went to IRC on Mo-Fr and stay until Im there.

it depends. When it stays in download mode without looping.. yes - maybe!
I need access to to the partitions which may work even in download mode via a special shell but it may requires MM and will not work for LL firmware (strange right? normally one would expect the other way around..).
That has to be tested though. On my device (locked H815) I had access but that may differ from other models.
Having root access makes things so much more easier
Testing if it would be possible on a bootlooping device would be simple:
You best use FWUL (recommended because here is all installed and working) or any other Linux with the LGLaf shell.
You would then connect while in download mode and you will have a shell like in adb.
I can guide you but again IRC is the best way to go here..
I'm searching since several days for such looping and even otherwise broken/defect devices but they all want to have a plenty of money for it (80-150 €!!)

Yes, QCOM 9008 mode. I can't flash the H815 image and make my G4 H815 again so, the only way to booting, it's flashing the LS991 image (and with Fastboot; I flashing every partition one by one).
I have Linux Mint whit adb/fastboot drivers, It's enough?

Hmm I can't help you unbricking. I just know that there are ways to do so. You need the correct drivers etc.. But well if you tried all this already we can try
Any Linux is ok as long as you can handle it
Havin TeamViewer installed may help too...
Well so if you like go to IRC Monday to Friday and we will see

Yes. today I have bad and good news.
First of all I had 1 single tester who was brave enough going the first approach I had. Unfortunately my first idea failed.
JL if you see this come back I said I can unbrick your device!!!
Ok so the good news are: I'm able to give you a near unlocked experience with all the things you love like installing custom kernel, recovery and ROM. Without actually unlocking!!! It's all tested on a h815 device which was never unlocked !
Near unlocked means it will behave like an unlocked device without actually unlocking the bootloader. Or to say it in other words: The boot chain verification is ignored.
The bad news: the process is not cleaned out yet but it requires one thing for sure: it will convert your whole device bootloader stack. The basic idea is to replace the whole bootloader stack with a modified one which allows all the mentioned things.
That way is very risky and I HARD bricked my device over 30 times until getting to the finally working result.
It also means that once your device is converted there is no way back atm. Flashing an original kdz will BRICK your device in 9008 mode! Not that bad because you can recover at any time but that's one thing you have to have in mind. It may never be a h811, h812..... whatever again. Until we find a corresponding and working bootloader replacement which may never happen. So no LG up or LG flash tools anymore! Instead you will have the qfil tool.
Again I know no way back to original state so warranty will be very very likely refused once you do this. Ok there is a way to blank out all partitions just for the case you need to send it really back. This should delete then most traces of this hack but no guarantees.
Besides this I don't know if there are any issues in functionality after doing all this. I havent made any tests for this yet. That includes phone calls, WiFi etc. I just checked booting ROM, booting TWRP, flashing supersu, getting root.
I will upload a video asap to show you the current result.
I need to test things further and of course I need testers with other devices. Again that process is risky and even if it worked for me it may not work for you (very unlikely but who knows). Manually forcing the 9008 is very easy and it may be required to do so. This may requires opening the device (I think it will work even without but I need testers.. ) so if you want to test... See you in the IRC.
If all this is working and verified by others I will provide the whole story ofc!
....can't believe that all these above took me 5 days in full time of work. And for what? I mean I do not need it because I can unlock my device OFFICIALLY..
BUT it was all for educational learning. I learned really a LOT of android and qcom during all these hours ...
Ok but Now I need some couple of hours of sleep
See u on the other site..

so........what now ? i have a F500k device . and i'm willing to test your method . but i'm not sure what you are saying here. ( i didn't understand a single word) . but if it means that i can't flash official KDZ or can't use LGUP....no problem to me.
just share to me how i'll do it and if i hardbrick how i'll restore it. thats all.
