Hello everyone,
I've searched everywhere I can think of to figure out how to solve my problem, and I assume the answer is hiding in an obscure part of an earlier thread on these fora. I was able to root my L9 P760 running Android 4.1(Jelly Bean) and from there naively assumed I could flash the recovery using ClockworkMod. After rebooting I've been getting the infamous "Security Error" screen. I've been able to get the "S/W Upgrade" screen, but that's as far as I got. I believe this means the bootloader is locked.
I followed a lot of instructions I found including using fastboot via omap4boot(http://forum.xda-developers.com/showthread.php?t=2119090) and the offline kdz flash(http://forum.xda-developers.com/showthread.php?t=2085344), but without luck. Fastboot would cause the phone to reboot, losing the "S/W Upgrade" screen and the kdz method would stall at 4%, leading me to find out that the phone needs to be in the "LG Update" USB mode, which I can't achieve because it won't boot.
I have two Macs running OS X 10.7 which can dual-boot into Windows 7. All software is up to date. I have experience using the command-line.
I hope there's a solution to this, and I hope that posting this here can help others avoid this problem in future.
Thanks in advance,
Pieter
Edit: I finally managed to flash a stock version of recovery, the x-loader and u-boot for Jelly Bean using the fastboot script from here. For those in a similar situation, I set the driver for the OMAP4xxx device which goes under TI devices(or something like that) and then I had to set the driver for a device called LG P4(or something, I didn't take a screenshot). I was then able to use the stock LG Mobile Support Tool, via the "Recovery Phone" option, to restore the newest version. However, it still won't boot properly. I get the LG logo when turning it on, and then the animation with the LG logo with the shiny effect on the smiley face keeps running in a loop. Is this the boot loop problem I've seen people asking about? How do I access recovery(and would that accomplish anything)? Any help would be appreciated.
Edit 2: I think I fixed it! I'm just documenting what I did to be helpful to other people. I had tried to do a hard reset earlier, but it didn't work. I tried it just now, and it worked, I got an droid with a progress bar underneath. Then it booted, and I heard the startup sound which I didn't know I was missing. I would still like to know in detail what I did wrong, and what I did right, and why it was right. Thanks in advance.
Simple, you probably did nothing wrong. Things just happen. I had this happen to me once. Security Error
However, I didn't install a custom rom or recovery img. All I did was flash a different kdz version (for my device). So my guess is that the boot img or other img, got corrupted.
I fixed my issue by flashing x, u, boot, recovery all in fastboot. Then I ran the flash update program again and it worked

How do you brick your phone. Did you try to hard reset it? Did you try offline flash or LG mobile support tool to recover your phone?
Hello,
Well this is my first time posting here. And my first time rooting a phone, I've rooted tablets before.
I bought an Lg Optimus MS769 and that same day I rooted it. I used this tutorial to flash the v20f T Mobile ROM http://forum.xda-developers.com/showthread.php?t=2085344
After that my phone didn't look like Metro anymore my phone loaded like if it was a T Mobile one. I wanted to install CWM and a custom ROM but in some tutorials it said that I had to have unlocked bootloader which I didn't. After going through some tutorials somehow while using the R&D Test tool my phone got stuck in the S/W mode and would not go anywhere else. The only thing I was able to do was turn it on and off, no hard reset or anything. Now when I try to redo the tutorial I used to flash my phone it stops in step 11 when the phone update tool is updating. It just says that my phone is not connected, that I have to reconnect it and click restart to resume update.
Does anyone know how to get it unbricked and back to "normal"? I'ved tried fastboot and that seems to be the only thing I can do with my phone. But all it does is go to a black screen with the lg logo and it's inverted. After doing this it turned my S/W upgrade mode inverted too! I did noticed that the logo in the S/W upgrade mode was green and now when it got inverted it turned blue. Maybe this was my imagination. I don't understand fastboot though because I can't do anything there, I press all buttons but nothing happens. I try fastboot from this tutorial http://forum.xda-developers.com/showthread.php?t=2119090 and when I get to step 14 I don't know what they mean by installing the drivers again. When I try to it just says they are up to date.
So can someone tell me in detail what to do? That way I don't spend too much time trying to figure out things because I'm short in time with work and school. Thank you and here a few pics of what my phone looks like the places where it appears on my computer.

Fastboot your phone, select option 5.
Fastboot again , this time use #1
type
Code:
fastboot erase cache
Remove the battery, unlpug the usb cable, press the volume+ and connect the phone to the computer. You should see S/W upgrade mode, Place the battery back in your phone. Try flashing with R&D Test .

What do you mean by select option 5 and then #1? When I'm in fastboot I can't do anything, its just the screen, no options show and nothing happens when I i press any buttons. I tried to do what you said and this what it looked like. When I go back to R&D the same thing keeps happening. It says there's problems communicating my phone with the pc.
This is how I fastboot it and how I did the fastboot erase cache like you said

I used the new fastboot you said. Well this got my inverted s/w upgrade mode fixed. Now it is normal and the little s/w logo is back to green. When I try to do the phone update it stops once again at 15%. The first time I flashed the v20f I had this problem but instead of going straight to s/w mode to upgrade the phone I had to just connect the phone and put it in lg software mode. When I did this and ran the update it automatically set my phone in s/w upgrade mode. But since my screen is only stuck in s/w I guess that is why it is failing the update. When I do run the fastboot at the end it takes me to the "yours" folder. Is there any files i can download and put in the yours folder and run them through the fastboot to maybe get the phone unstuck in the s/w upgrade mode?
Well I feel a little more relieved and thanks for your help.

I put all those commands then tried to do it again. Now it stops right at the Analysis part saying that USB cable and my phone are not connected. Or something it gets all the way to the Update part and also stops at 15%. After I did those commands I went again to do the faboot option 5 then 1 and tried it again and the same thing keeps happening. I even tried doing option 7 because my phone came with jb already and still no luck. When it is updating the phone does shuts off("disconnects itself") and then turns itself back on. I don't know if that is normal.
On the R&D test tool. What should the work directory be? I changed it at one point, is it the same as where you have the kds file in? The first time I did this I had phone mode in emergency and then I see another video that says that phone with v20f should keep phone mode in DIAG.

In fastboot, did you choose option 5 to flash x-loader & uboot as Lelus said? Most user with JB need to do this before R&D tool can detect their phone in S/W update mode (and get pass 15%).
For DIAG mode in R&D tool that will work only when you can turn your phone on and put it in LG software mode.
Last option please try to use LG mobile support tool to recover your phone. And to do this you must remove some lines added for offline flash from hosts file because it need to download file from LG server.

Yup I even did it again to test it. In fastboot I pick option 5, then option 1 to erase cache and then when I run the R&D tool It passes through analysis and download just fine. When it reaches the update I notice that at 4-5% the phone turns itself off or disconnects itself and then it connects back and reaches all the way to 15% and after a little while being on 15% it says that there is no connection between my phone and computer, to reconnect it and press restart to resume update.
The Lg tool makes me choose the phone I got and I picked the metro pcs ms769 and downloads the drivers. I tried doing the tmobile p769 but they only have the t mobile p769bk and when I choose that one it says files not found when downloading. So i proceeded with the metro pcs ms769 once I connect my phone and its detected I go to options and upgrade recovery. It then automatically finds my IMEI number to start. Like on the R&D tool I get past analyzing pc settings and download even though the download takes about an hour. When I get to the update it stops around 4% after the time elapsed reached 3 and a half hours I just closed it.
When my phone first got stuck in S/W mode I could unplug it and it will still be there, even when I turned off the phone and took out the battery. After a while now it only turns on when it is plugged in into the computer, if it is unplugged nothing happens when I try to turn it on.

If lg tool doesn't work , nothing probably will, unfortunately you might not be able to restore your phone. I remember few people in same situation. Hopefully the warranty will cover it.

Hello akwlb,
First of all I will say just one thing that is don't lose hope, OK. Now listen to me carefully. I have also faced exactly same situation. I was using my LG L9 P765 with stock JB V20A ROM, Unlocked Boot loader and Touch CWM(Custom Recovery) installed on it. Apx. A month ago I got a notification from LG that a newer version of ROM is available to download. I got excited and downloaded that update and installed it, without thinking that I have installed Custom Recovery not the Stock one. So phone goes off to install updated and restarted, LG logo appears and then CWM screen. I thought that it’s a normal issue, so I turned phone off and started it back but again same thing happened. After that my phone never booted up. For next 10 Days I tried every know trick that I know about rooting and flashing. I searched the whole XDA Forum, Thousands of other forum & sites but no luck. I was facing worst situation than you, coz m having connection error on LG flash tool, no ADB working, no fast boot working. so at the end one day I was trying different tricks on l9,I flashed some "omap" drivers form LG Optimus G forum, I flashed those drivers successfully, the phone goes off and it never turned on after that, no any response to pc, no power on. So I ended up with a fully bricked L9. After all of this I have only one hope left and that was Warranty. When nothing left to do, I took my Phone to LG Service Centre. I told the LG Service Guy that "A few days ago I got an update notification, I updated the device, but it never booted up again". Service Guy took my phone and connected it to his computer, but there was no response. He tried several other tricks but L9 didn't responded any one of them. So the service guy issued me a Service Job Card saying, “Collect your phone after 10 Days, I have to change its mainboard". I asked him whether this will be done under warranty, he replied "YES". After 10 days I visited the LG Service Centre and collected my L9 in 100% working Condition, without paying any penny. So my advice to be take your device to Customer Care. Don’t worry about ROOT, even your device is rooted, may be LG guys not goanna repair it under warranty, but it is sure that those guys defiantly bring it back to normal. May be they charge for the repair of device, but it should not as high as you are not able to pay.
:victory:SO THIS WAS MY STORY HOW I GOT MY L9 BACK, EVEN AFTER TOTALLY BRICKING IT UP:victory:
THE ONLY THING GOT CHANGED IN MY L9 WAS IT'S IEMI No.

Thank you very much
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

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...

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?

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...

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.
Good luck...

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?
Hi all, attempted to root my phone today following this guide.
I got right up to step 9 but upon trying to reboot and launch from TWRP I began to have trouble. I've been able to access TWRP once, but after confirming install of SuperSU (step 11 here, my phone booted to the LG splash and I got the boot loop saying 'Your phone is unsecure, bootloader is unlocked' or words to that effect. Orange ! triangle.
I can launch to fastboot, or download mode. Turning on to a factory reset sends me back to a boot loop after confirming I would like to reset (leading me to believe I've not got a stock ROM in there at all).
Now when I try to flash any version of TWRP from command prompt in my ADB folder, I'm told my phone is corrupt and it won't allow me to flash.
Alternatively, trying to flash a stock ROM doesn't work either. LGUP does not recognise my model, it only shows COM Ports: [COM4, H85020s]. I've also tried using UPPERCUT but I get the following error: "Error reading from file: C:\Users\...\Roaming\Temp\F9FB5BD\TempFolder\UPPERCUT.exe. Verify the file exists and that you can access it." I've attempted running UPPERCUT from various locations, extracted.
I'm on Windows 10 and I've been trying desperately for the last 12 hours crawling through this site/ other articles for some kind of solution to give my phone SOME kind of functionality. Ultimate goal was LineageOS but now I'd be more than happy getting back to stock. I'd really appreciate any help, hope I've given enough information.
I followed the steps to ChazzMatts guide and used the US99810d_01_0411 kdz file to flash on the patched LGUP, I got an error eventually and attempted to get it out of download mode and restart my phone. Now it is stuck booting repeatedly on the LG V30 splash screen. It shows the logo and resets over and over again. I attempted master reset as well to no avail, it shows the erasing screen for about 4 seconds and goes back to bootlooping. Is there any saving this phone? Is it gone?
I think you're saying you got an error during the KDZ flash, is that correct? If so, then you need to complete the flash properly. It would also help if you tell us what the error was.
Go back into download mode and reflash the KDZ... if you get an error, you need to fix that before moving ahead and trying to boot the phone.

Yeah solved it just now, now I'm having trouble with unlocking the bootloader, keeps saying it's waiting for any device no matter what.

Read the Section 7 Trouble Shooting tips. Something isn't communicating properly with the phone. Sometimes it takes even trying a different PC. But first try reinstalling drivers, changing cables, changing USB ports. Just go down through the list from #2 to #13.
