TeenyBin for LGNPST
E971, E973, E975, F180*

Don't give me all the credit. Just as much goes to artlan for figuring out the tables and table offsets.
Special thanks to xonar_ for his LG Bin Firmware Extractor and releasing his source code.
Thank you Shelnutt2 for everything you do for the entire LGOG community.
Thank you k7raid for testing the first bin with major SBL changes.
And last and also least.. ha ha.. sawdey21 for suggesting the "updated" name change.
TeenyBin. Patent Pending.
Be sure to show them all thanks.

Background

After seeing tons of soft bricks on both the forums and IRC we have decided to look into how LG .bin files work. We've "cracked the code" and have been able to rebuild the .bins.. making the repair process both faster and easier. Normally the user must download a large .tot/.bin file(1GB+) to repair the phone. After a long download and using LG Tools to flash the phone.. it is then completely stock... requiring a "re-root" and running the FreeGee unlock again. On top of the time it takes to download/flash... users also have to deal with the instability of KDZ Updater. This new method works around that software and now uses LGNPST.

TeenyBins are meant to do the bare minimum... fix your soft bricked LG OG and get you back into your rom.. or custom recovery to flash a new rom. These new .bins are as small as 31MB depending on what we build into the .bin. This means smaller files, shorter download times and a phone that's back up and running within minutes.

Other perks include...
Unlocking the bootloader.
Preinstalled TWRP Recovery.


TL;DR
You can use this method to quickly fix your softbricked LGOG. Instead of using a 1GB+ .kdz file and KDZ Updater you are now using a 30MB .bin file and LGNPST.


Directions

TeenyBins will quickly repair your soft bricked device. They will also unlock your phone and install the latest TWRP recovery. These .bins should be safe for any E971, E973, E975, F180* device.

1. Download TeenyBin .zip and extract. You are going to use the .bin file inside along with LGNPST. LGNPST can be found in the "Additional Info" section at bottom of this post.
2. The TeenyBin LGNPST flash should take 30 seconds or less... your phone will reboot at either 67% or 85%. The flash is complete. All finished.. maybe...
3. Your phone still may not boot up!! If so you must reboot the phone.. boot into fastboot.
4. From fastboot, boot into recovery. In recovery you can flash a rom. All fixed. No rom on internal sdcard? Use adb push.
5. Nothing working? You're doing it wrong. Did you read this entire post... including everything under the "Additional Information" section at bottom?

Fastboot = Volume up + power
Recovery = once in fastboot.. press volume down, pause, volume down then power button


TeenyBins

TeenyBins will repair a soft brick, unlock the bootloader and install custom recovery.

Fastboot = Volume up + power
Recovery = once in fastboot.. press volume down, pause, volume down then power button



DOWNLOAD:

E971.E973.E975.F180 Original TeenyBin - This is the default TeenyBin for every E971, E973, E975, F180* device
F180_TeenyBin-AA.bin - Chinese F180 users have asked me to make a new TeenyBin with new recovery. Here it is.
Current included recovery: TWRP 2.5.0.0 - Thank you Dees_Troy!


Additional Info

Q: I flashed the small bin and still can't boot back into my phone.
A: First of all... it's a TeenyBin... but anyway.. booting directly back up into the rom may not always be possible. Your /system or boot.img may be damaged. You were soft bricked remember... how do you think the soft brick happened? In this scenario you will have to reboot into fastboot.. then enter recovery... and reflash a rom .zip

Q: I don't have a rom .zip on my /sdcard so how can I flash a .zip?
A: Use adb while in recovery mode to push a rom to the phone. Google is your friend... look into adb push or adb sideload.

Q: What is adb?
A: Get out!

Q: Can you make *custom .bin here*?
A: Maybe... but I am lazy so make a good point.

Q: How do I know if I'm soft bricked or perm bricked?
A: For most soft bricks you will see a LG or Google logo and then a black screen. You can also still get into download mode. If you think download mode may not even work, connect phone to a Windows computer and check device manager... if the phone is detected in a "QHSUSB-DLOAD" then there's a good chance you're perm bricked. Otherwise.. you may just be a n00b and aren't doing download mode correctly.

Q: Where's that LGNPST info you mentioned?
A: Hit the Show Content button below
LGNPST Guide

DO NOT ASK HOW TO USE LGNPST OR A VIRTUAL MACHINE IN THIS THREAD.
THIS IS A TEENBIN THREAD. THE FILES AND GUIDES BELOW ARE A BONUS ONLY. RESEARCH. READ. APPLY.


Downloads + basic guide HERE

Update - added a virtual machine with pre-installed LGNPST to the link above. This will be for those that aren't on Windows.. or just having install issues. Thanks to k7raid for that! Some files may need a password to extract... PW = lgog

BELOW IS A MORE DETAILED GUIDE FOR THOSE CONFUSED OR STUCK.
READ IT ALL AND MOST QUESTIONS SHOULD BE ANSWERED



Notice at the top it says LGNPST ACG and not some other weird version? And notice the version numbers. If yours don't match up then you installed the wrong version!!
1. COM port will show up if phone is connected properly in Download Mode. LGNPST will switch and say Emergency Mode.
2. Press the DLL button towards the bottom of Emergency tab.
3. Press the BIN button towards the bottom of Emergency tab. You should now see both both file names scrolling in LGNPST like the screenshot.
4. Press that START button.
5. A windows will pop up saying you will lose data.. you will NOT lose any personal data.. hit OK.
6. If LGNPST is working properly it will take 20 seconds or so before LGNPST hits 67% and reboots your phone. DONE. After your phone reboots at 67% or 85% it's safe to unplug and use phone.
7. If you still can't boot up, try booting into fastboot. Can't get into fastboot.. try flashing the AltBin. Still can't get into fastboot? you're doing it wrong.


Q: LGNPST Won't open and says "usb dongle not detected"
A: In the lgnpst folder where u ran the .bat to install it should be a lgnpst_acg.exe file somewhere. Copy it to your program files > lg electronics > lgnpst folder overwriting the current exe in that folder. Should work now.

Q: There's no LGNPST_LS970/dll file to select in LGNPST.
A: The install.bat should have registered your dlls but something went wrong. Check the link in the next answer.

Q: I still can't install LGNPST... help?
A: Check out this link.

The point of this tool is to flash when you don't have a recovery, when you can't boot, you know, soft bricked ? Making a zip file that you can flash by recovery when you have NO recovery is stupid.

After following this guide I can access fastboot, but when trying to flash any rom from there, may it be ThinkingBridge, CM etc. I receive the following error:

Could you give me some advice, any advice would be greatly appreciated.

Problem solved by deleting the line:
assert(getprop("ro.product.device") == "e975" || getprop("ro.build.product") == "e975");
in updater-script

Thanks to NeoPhyTe.x360

i need to make new teenybins for each and every model.

u have the E975? or was it converted from another device?

currently the teenybin includes TWRP which is made for LS970(sprint optimus g). I need to edit the recovery so it thinks its E975 instead of LS970 i think. Does E975 have its own TWRP? or any official recovery for that device specifically?
