I recently picked up the P769. It had V20F already installed on it, but I wanted to unlock the Bootloader to get CM10.2 on it. I went through the steps in this thread:
http://forum.xda-developers.com/showthread.php?t=2277639
But, after I gave the LG Recovery Installer Superuser permissions and restarted into CWM, I attempted to follow the steps, but I'm guessing I did something wrong, because it restarted to the Security Error logo. I was able to get Fastboot and now I can get it back to S/W Upgrade, however, when I try to use the LG Upgrade tool again, it stops at 15% after attempting to connect to the phone roughly 5 times and failing.
Is there something I missing with getting the phone to connect to the computer properly? I'm unsure how to handle it. Any help would be greatly appreciated.

Then try to use LG upgrade tool again.
I recently rooted my Lg G stylo (Metro). I was messing around with the Clockwork Mod Recovery. Long story short, I had to reboot into recovery but I keep getting a "Secure Booting Error" "Error code 1003". It keeps restarting over and over again and the same message keeps popping up. The screen doesn't pass the logo, it just shuts down after the error message shows up. repeat
There is no way to access the homescreen or anything. I trying to factory reset by holding the VOLUME DOWN + POWER KEY. It works. I get a menu that says Perform a factory reset , [Yes/NO]. When i click yes, the reset begins but after a while it shuts down and continues to repeat the same message. "Secure booting Error". "Error Code 1003". I have also been able to acces download mode where the screen would say firmware update/Usb. But idk what to do after that. Im pretty sure its not bricked since it still turns on.
Did you unlock the bootloader before you rooted or did you use one-click rooting apps to root your phone?
I have the same problem

i have the same problem
As a new owner of an LG G Stylo MS631 (the Metro PCS model) I had the same issue just yesterday when working with GameTheory's Katana ROM and he pointed out that when the Secure Booting Error Code 1003 shows up it's because you have to go into the Developer Options (tap the build version 7 times under Settings - About phone - Software Info, back out two steps and then find the new setting just above About phone) and check the box next to "Enable OEM unlock" - this doesn't unlock the bootloader but it does allow you to use tools like TWRP without hassles or some of the reboot to recovery apps.
If you're getting the error and you can't get past it in any respect, you're going to need to flash the factory KDZ to get it truly useful again. That's what I ended up doing because there simply was no other way to get recovery or anything else working.
Flash the KDZ back to pure stock, go into the Developer Options and enable that option (Enable OEM unlock) and then go about rooting/flashing TWRP/etc.
Good luck...
FIXED

Hello, I just soft brick my MS631 this morning. I had the phone rooted perfectly fine withthe katana ROM. Then, I stupidly use the reboot recovery option that is baked into the ROM withough developer options enabled and OEM chec (I forgot). Now, I get the looping Secure Booting Error 1003. If, I do the factory reset step (hold power and vol down) I get to the factory reset options, but when I select YES, it'll go through the loop again. HELP please, as I A) cant afford another phone right now and B) don't want to go back using my Windows 640 LTE phone with MetroPCS.

I did a similar thing. Go to HERE and follow GameTheory's unbrick guide. If you have problems downloading the KDZ like I did, then try getting it HERE
I actually did GT steps right after this post. Im now back on Katana and learned from my mistakes lol
I accidentally used king root without developer mode enabled
I also bricked my phone to the point of it being unusable. I am running on boost mobile and I am using android marshmallow 6.0. My phone said it was rooted after using the 1 Click root app and I went to start it and it now says 'security ERROR MODDED 1003'. I am stressed out at this point and I have reset it via developer menu about 3 times to no avail. I am familiar with rooting and roms but I'm not really used to using code. I'm stock everything and I am running on Boost mobile. If anyone can find a boost rom for me to use it may be possible to put my phone in download mode. I do have an sd card if it is needed to load a zip on. Please help me get my phone booted again! I believe a sprint KDZ may work but I can not find one for download anywhere. Thanks !
This may happened to me too. I am on the Boost version as well. I used the king root app to root the phone then I tried to install the adaway app. When the app told me to reboot the phone, I clicked okay but I hit the secure bootloop. I didn't even try to install a recovery. How do I fix this?!?!?!

What if you cant get the phone to do anything outside of the boot loop?

I wish I could offer some help but I haven't owned an LG Stylo since I made that post - I literally sold that one the following day. Hopefully someone else might be able to provide some assistance.

Sorry for the bump on this thread. I followed the unbrick guide mentioned here, and all seems like a GO... except a lost service. Screen Lock says "No Service", but I am receiving text messages from contacts.
lg ls770 (boost)
Lg stylo ls770 boost
My stylo is showing the same error 1003 and on bootloop. Can someone help me figure out where to go to get the fIles to restore it back to stock.
PM or email me if you can help TIA

the issue im running into using the tutorial to flash the metro kdz is it says it got disconnected from the server. any ideas?
Hello guys and gals, so i just recieved my LG V10 H901 and tried to follow https://forum.xda-developers.com/tm...step-step-guide-rooting-lg-v10-using-t3382631 this guide, but eventually i ended up with a brick after trying to flash the .tot file.
I keep getting
Boot Verification Fail
- cause: MISHMATCH_SIG_LEN
The TWRP recovery i had is now gone, and i can't access Bootloader. I can enter Download though. I read a lot of things around the problem, but i always stuck on various software versions or phone versions i can't really understand. Is there any way to get the phone back working? Before i try any method i just want to be sure i wont mess even worse (if that is even possible).
I tried UnbrickMe thread, but it says only for soft version:h90120j I have soft version H90120c (i haven't performed the update to MM) so i don't wanna try without being sure its going to work.
I m leaving for vacations in couple of days and i don't have a phone :/ please give me your lights.
Also LGUP wont see the phone, the same for ADB.
OK I Fixed it!
I was able to get out of this maelstrom of bootloops and to finaly flash the default ROM (you can find it here https://forum.xda-developers.com/tmobile-lg-v10/general/stock-h90120j000712-kdz-t3436249 )
So what i did is to remove battery for 10 seconds
Put The battery in
Hold volume up button
Plugin the phone to my PC through USB
Then download mode will start
I opened LGUP and fortunately it was able to see my phone.
Then went to Upgrade and flashed the kdz file.
All went smoothly and the phone is back working.
Hello everyone, I have been a fan of your forums for quite a while, you guys have an awesome community. I have been attempting to unbrick my VS990 with no success, I have LGUP and all of the proper dll files in the proper folders, I have two .kdz. One is the stock kdz, I can not get to work at all due to anti roll back (no matter which option I choose) and the other is the current kdz. I got that one to accept using update, but it did not fix my phone, it is still stuck in boot loop. and using refurbish I get an error message saying that it is not supported by that kdz. LG UP is fully recognizing my phone, I found the .kdz files no problem, I believe that I have followed all of the steps here >> https://forum.xda-developers.com/lg-v10/general/guide-lg-v10-stock-firmware-to-stock-t3224170 any help at all would be appreciated. Side note, I have not rooted or installed a custom recovery.
I would also like to add, I can not do a hard reset. Every time I attempt the phone either locks up when I hit the power key on yes to confirm factory reset, or sometimes it reboots to LG splash screen and locks up then. I am starting to wonder if there isnt a hardware problem with the phone instead of software.
I tried updating to android pie, then the phone reset and now its endlessly stuck on the logo, I cant turn it off, only thing that seemed to work was getting into the master reset menu, but even after reset the phone returned to the logo. It also doesn't connect to my pc. Please, what can I do, do I let it run out of battery? Is it gone now?
I'll let ChazzMatt answer this, as he is the expert. But I imagine he'll want to know which model number of V30 you have? Which ROM were you on? Is it rooted/BL unlocked? And how did you perform the update (OTA, LG Bridge, LGUP)?
Edit: Sorry, Chazz, I should have just waited, seeing you were right behind me

US998? There's 5 different workaround methods in the KDZ thread, in posts #2 and #6.
But a couple need unlocked Bootloader and TWRP. The others need you to manually go into Download mode. After THAT, your Dev Patched LGUP should recognize the phone. You should have read all this before attempting update.
IF you are on US988 firmware...
Fixed it, thanks
