Need help ASAP, can pay for you to fix my phone

Apparently my phone is bricked..
I rooted my phone a long time ago when I first got it, never installed any roms or anything.
I get this message on the LG Screen:
"Secure Booting Error problem
Device UnLock!!, so Boot Success!!"
I've tried multiple ways to fix my phone and I can't get any of them working.
I'd be happy to pay the person in a steam game of your choice!!!!
Thank you

I tried but the drivers won't install correctly. They did once, but it just said something along the lines of "Ready", and never did anything even after plugging and unplugging.

That message upon boot is normal if your phone has been modified. Mine says it too and my phone is booting up perfectly fine. In fact, it always has said that from the day I first modified it.
Most likely your software is just bricked. First of all, BE HAPPY YOUR PHONE IS JUST SOFT BRICKED! :laugh:
(I recently hard bricked my phone by accidentally flashing a file for a completely different phone... phone was completely dead!)
You need to provide more info for anyone to help you, whether it's me or someone else:
1) What phone are you using? E980, E988, E986, F240, etc etc.
2) Do you have a custom recovery, like CWM or TWRP? (I'm hoping you are because getting software back will be easier).
2.1) Can you boot into this recovery? (hold volume up and power button at the same time. The boot animation will begin and the screen will then shut off again. Once it does, let go of the power button, but keep holding the volume up key. The phone should reboot into recovery. It's tricky to do, and if any other readers notice that I described it wrong, please correct me!)
3) Do you ever see the LG boot animation? (The animated LG logo)
4) Once you see that message upon boot, do you wait for it to pass and hope the phone boots, or do you panic and force the phone off?
5) To get the drivers to install for using LG FlashTool, have you done the following?
- First download and install the drivers from the LG site (I'd link you to it, but I only know the link to the E980 drivers. I don't know what phone you have).
- Once installed, plug your usb cable into your computer, but not the phone.
- Hold the volume up and volume down buttons at the same time while plugging the usb cable into the phone
- Phone should now boot into Download mode and your computer will start installing more drivers. Let them install.
- Change the Com port of the phone to Com41 (ask if you don't know how to do this)
- Continue using the LG Flash Tool.
I apologize if any of this sounds like I'm insulting your Android phone intelligence. I don't know how much of this stuff you know.

No, no I understand!
1)E980
2)I have TWRP.
3)I only see the LG Logo, the error message and that's it, it goes right to TWRP after that.
4)I wait for it to pass, and it goes to TWRP.
5)I will try this on a different PC, because when I boot into download mode and plug in the phone, the drivers attempt to install but fail. I have attempted to re-install them multiple times, but I'll give it a shot on my laptop tonight, and let you know if that works.
Thanks for the help, and I may PM you later!

Have to tried install cwm through twrp then wiping clean and installing a ROM ...
2SHAYNEZ

Me thinks his botloop is due to a bad rom flash, flash a rom(EZ kat is a good choice if you want the AT&T stock experience). follow shayne's instructions.

@AustinBobDox:
I know EXACTLY what the problem is. You ran into the notorious recovery bootloop, which seems to be happening to many Kitkat users running recoveries incompatible with KK.
I had it a few times myself while using CWM, PhilZ Touch, and TWRP (Yeah, I got them on all 3!)
Unfortunately, the TWRP and CWM recoveries posted in this forum cause this bootloop randomly if you have the stock Kitkat rom installed (whether rooted or not). Personally, I have not been able to get out of it. I ended up flashing a "fix" that was supposed to get me out of it, but... it was for a completely different phone (an HTC) and it hard bricked my phone.
SO DON'T FLASH ANY "FIXES"!!!!!!!!!
Technically, the ROM is perfectly fine. I read that this bootloop is caused by the phone setting a flag that tells it to boot straight into recovery. Basically, when you initiate the recovery boot, it sets this flag, and when you reboot the phone, it's supposed to clear the flag. In the case of this bootloop, it doesn't get cleared for some reason.
Luckily, since you are on TWRP, you can try this:
Open the TWRP command console thing (I think it's under Advanced or something).
Type this command EXACTLY:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
DOUBLE CHECK YOUR SPELLING, SPACES, ETC!!
EDIT: I put a part in bold because it's .1
The decimal could easily have been missed if reading on a smaller screen or something.
Submit the command and try to reboot to system via the TWRP menu.
If this doesn't work, then you have no choice but to use the tot method once you get it working.
EDIT: Oh and before getting the drivers to install by plugging in the phone, install these drivers:
http://www.lg.com/us/support-mobile/lg-E980
(Look under Software Update tab)
Whether the command works or not, once you get the phone up and running again, install this recovery:
http://forum.xda-developers.com/showthread.php?t=2760895
It's the only recovery right now that's definitely working on Kitkat without the bootloop issue. The only downside is that it can't mount the external_SD, so anything you flash must be on the internal storage.
EDIT: Oh and in case you can't tell, don't flash this recovery! You install the APK in Android and then open the app and install recovery from there. You need to root first though.

With this recovery bootloop, even if you flash a new rom, the bootloop could remain. I wasn't able to try a whole new flash, but I did try restoring a backup (different things, I know) and I still kept booting into recovery.

Oddly enough, this has happened to me on all cwm versions, flashing the hacked twrp was the only way i could get out of it. I use cwm to flash roms, twrp i only use when in bootloop or to flash mods.

Did you make sure under, device manager, your port is set to com 41 for your device?

[Q] My G3 is Softbricked - $20 to the first person that can help me fix it!

I'm going crazy here and I need my phone to work!
I have an LG G3 on Verizon.
I rooted it and edited a part of build.prop to change the DPI which got the phone stuck in a boot loop and kept popping up "the process com.android.systemui has stopped.
I tried clearing cache
I tried booting in safe mode
I then did a factory reset
My phone boots up to the Setup Wizard screen but I am STILL getting that systemui error and a com.android.phone and I can't get any further than that screen.
I then tried to use the LG FlashTool to just wipe the entire ROM and replace it with the stock one from Verizon.
This gave me a "Model Information Check FAIL!" error but I DO have the right ROM for my phone. There's only one for the Verizon G3 as far as I can tell
This led me to realizing that there is something in the build.prop that's making LGFlashTool think the proper rom actually isn't right.
I then installed the Android SDK so I can ADB into my phone. but whenever I run "abd devices" nothing shows up in the list.
I was told USB Debugging needs to be turned on in order for this to work, I don't remember if it's turned on or not with my phone and I can't get past the Setup Wizard to edit anything. I wonder if ADB is even running properly on my phone or if these errors are stopping it?
I will gladly paypal someone $20 if they can get this working for me.

Did you tried this?

8) When the firmware is downloaded, boot your LG G3 into Download Mode. To do this, press and hold the Volume Up key and then plug the USB cable.

One of my friends saved his phone by this guide

Download mode - LG PC Suite - Restore update error.
1. Remove battery
2. Boot phone into download mode
3. Open LG PC Suite - restore update error
This method have saved me a few times.

Will adb work in one of the recovery modes even if it wasn't enabled in the full boot mode? If so, start there.

Regarding your USB debugging question, you would have had to turn it on in order to root the phone originally, right? If so I imagine it would still be on unless you unchecked it. You have the proper drivers set up? Anytime I've encountered issues with adb devices not returning any results the issue has been drivers.
Good luck.

What do you mean recovery modes? You mean like Safe mode? I actually haven't tried that. I'll give it a go.

I believe I have the proper drivers, I installed drivers and the phone is showing up in device manager as Alright.

Try hooking it up to the lg support tool and select uprade recovery.
Download and install support tool

[Q] How do I get download mode working?

I rooted my phone about a month ago using PurpleDrake and now I'm on SkyDragon G3 V0.0.5 w/ TWRP. I had never been able to boot into download but thought nothing of it since it wasn't crucial at the time. Then, yesterday I accidentally took the new OTA update, but was able to fix it with the ADB commands that others have posted. Being able to get into download mode would have made life easier so I tried to fix it today. Flashed stock boot.img and tried to re-run PurpleDrake to see if I missed a step but it won't detect my phone for a reason I don't know. At my wit's end.
Not being able to get into download mode is a concern in case I ever to fully return to stock. Wondering if any one has some insight on how I can do that or if there's some image file I need to flash, etc.?
Thanks!

Thanks for the reply. Sorry, I could have been more clear in my post. I have visited that thread and held volume up while plugging my phone in, but all that happens is the LG logo screen pops up for a few seconds, then the phone shows the charging percentage. When I try to do it from the advanced reboot menu when the phone is powered on, it simply reboots into the system. Same deal if I try to do it from TWRP. Really not sure what I'm doing wrong here. Is it possible that I somehow corrupted the bootloader or something else that's hopefully fixable?

I think you made a wrong procedure.
Take the battery out and put back in.
Press and hold volume up button.
Plug in the cable.
Release the button when you see download mode screen.
In addition, make sure you have LG PC Suite with phone driver installed.

Thanks but I have already done this with the same result as I've described. I know how it is supposed to be done with the hardware keys and I am using the stock data cable. Even watched a YouTube video demonstrating how it is to be done. Are there any other possibilities?

Just tried it with my nexus 7 cable on a different usb port (which I had done couple times before) and it worked this time! Not sure why or how but appreciate the help, everyone!

I encountered a few errors first it was the PTP ,it would get stuck at 90% then I switched to MTP and it reached 100%.
I noticed that everytime I unplug the phone or switch between MTP or PTP the phone makes a sound and it says its installing drivers again. Could that be the problem?
I need some help with this , I have been trying for 3 fu$#@%^ hours and I cant get it to work.

Seems your in a pickle.. I used this site and it worked http://lgg3root.com/
Also plug it in and if you are PC savvy look in the device manager and see if its listed. If it is remove it (it may be listed as unknown device). then unplug the phone reinstall the driver then plug it back in and try the root method again. Hope this helps! sorry no one else is bothering to even give a helping hand.

of course for flash first twrp and after flash all autoprime files and after this .. impossible to have access at twrp . hard reset work . but nothing happens boot loop kdz for rollback doesnt work too . still blocked at 9% on the tool and 0 on my phone and ask me to remove the battery etc etc i did that too much time . but for nothing and the worst . bridge .. support tool recognize my phone like H815 then no driver problem

i have unlocked BL but didnt have access to ADB and Fastboot(idk why) and got stock recovery after flashing so no chance to go in TWRP

Does the phone freeze at random times? Like no matter where its at, sometimes it boots to the operating system?

Hardware
It's starting to sound more and more like a MEM BLOCK corruption..

Have you tried this: Firmware to Stock with kdz and tot?

Noo

What's that and what's the remedy? And usually what causes it?

To me it used to happen sometimes while charging. I had to manually switch off the screen and when i switched on the screen, it became normal for a while. I thought it was due to heavy xposed customizations.

Try this:
copy all zip files you need to reflash (10D or similar) to a memcard
Also download latest twrp and copy it to the directory where you have adb.exe
Open a Command prompt on your PC (where adb is located) and powerup the phone,
open up the Device Manager on your PC to see when the adb device is there,
in the moment where you see the adb device fire up the comand:
adb reboot bootloader
if that works enter the comand:
fastboot boot twrp-2.8.7.0-h815.img
this will boot directly into Twrp without flashing twrp and you can try things from twrp
I hope this will help here, helped me with the phone from a friend of me who had a similar problem.
