H950 5.1.1 V11z Bricked/Bootloop: LG Security Error, Authentication Fail #9



Hello

A brief timeline of events leading to this thread:
1. I purchased a G-Flex2 H950 from Ebay for 0 and was supposed to be upgrading from a Galaxy S4-I337.
2. Received my device yesterday and set out to update to 5.1.1 & root the device to remove bloatware.
3. I was able to update to 5.1.1 V11x using my StraightTalk sim on AT&T network.
4. After many frustrating hours of trying to root using different methods, I finally was able to root using the technique mentioned in this thread: http://forum.xda-developers.com/g-fl...5-1-1-t3178354
5. A nice complement to point "4" above was the firmware update to 5.1.1 V11z.
6. Extremely happy that I was ready to rock, I set out to delete all the bloatware from my device.
7. First surprise obviously was the inability to remove a bunch of AT&T apps because "APK could not found" error.
8. Like the idiot that I am, I went ahead and deleted the "rootsystem.img" from the internal memory (unnecessarily, blame my OCD!).
9. Now after I finished de-bloating the device (or so I thought), I rebooted it and to my horror... I see the error message:

LG Security Error
Authentication Fail #9

10. I attempted to get to the recovery mode and deleted/erased all data & settings. No dice!
11. I'm still able to get to the download mode using the Volume-Up & USB connect method (& this is why I'm cursing myself at point "8" because I could have re-used the easy root method again to flash the img file).
12. I tried to use the "LG Mobile Support Tool", it recognizes the device correctly as "LGH950" but says V11z is the latest software update.

My question to experts: How SOL am I? I don't think LG would honor my warranty since the purchase is NOT from a authorized dealer/reseller. So no chance of warranty repair/replacement, no?

I looked everywhere (for close to 10 hours) for KDZ & TOT files to even attempt something. But I couldn't find anything for H950. Man, I hate AT&T so much now... Why couldn't they just leave the bootloader unlocked? Or LG (AT&T?)even provide the necessary files to start off with?

Could someone with more knowledge please offer any help? Meanwhile, I've pretty much resigned to be joining the queue full of others with bricked H950's...



Issues with 2 Factor Authentication After Marshmallow Update?



I have a Nexus Player, that got the Android 6.0 Marshmallow update. I had to remove and add a Google account back. The account has 2 Factor Authentication. The Nexus Player goes throug the process of taking the ID, Password and the 2nd factor passcode. But then, it goes to the Google Account Security Web Page and gets stuck there. If I hit the home button, then going into settings, the account has not been added. It seems Marshmallow on the NP has issues with adding a 2 Factor Authentication account. No such issues using an account that does not have 2 Factor Authentication.

Anyone else had this issue? Any way to add a 2 Factor Authentication account, without ever removing 2 Factor for any period of time?
