[Android Q&A, Help & Troubleshooting] bobdamnit:
That sucks. I'm sorry to hear that man. I really had hopes that we could bring it back. It still might be fixable, however its beyond my knowledge.

I broke my phone yesterday. I dropped it on concrete in a scissor lift from about 15 feet up. It didn't survive. On the plus side, it still powered on even though the screen was useless. I was rooted and running custom recovery. So I pulled the battery, went home for lunch, plugged it into my computer while holding volume up so it would boot to fastboot mode. Then I proceeded to flash the 11B laf image to the laf partition, fastboot erased recovery, fired up LG Flash Tool 2014 and flashed the KDZ. I knew that it worked, however I had no idea whether it still passed the "Modified" status in Download mode.

I went back to work kind of nervous about it, knowing I was going to the Verizon store to turn it in under insurance. They plugged it into their computer and did a bunch of things, asked me for $75 (which I paid), and told me I'd have my device back in 3-5 business days. I asked if I could swap with a new one and he told me that the G Vista VS880 is discontinued with Verizon. I'd have to swap to a new phone. I wasn't willing to do that just yet, as the newer phone was actually worse, so I'm without a phone for a few days. They offered me a loaner feature phone (flip phone), but I have an old original Moto X that will at least make calls/texts (but not data and I don't know why) to get me by.

In the mean time, I'm going to ask around about getting at least a proper recovery made. I've got my build machine setup properly (I tested it by building CM 12 for my original Moto X, which went off without a hitch.) and I have LG sources, so I'm going to start building Cyanogenmod for our device. Should be pretty entertaining, to say the least.

I wonder if you can flash back to 10b on the D631 after updating without bricking. I know that with Samsung if you try, it'll brick the device since you can't drop back to previous bootloaders. Not very familiar with LG. Seems it works with the Verizon version of the phone. Anyone know?
[Android Q&A, Help & Troubleshooting] bobdamnit:
No, we don't know yet. At worst, it wouldn't flash like trying to downgrade the VS880 without doing the rename trick, I think.

If your willing to test it, please post your results. I have been wondering the same thing for a few days now.
[Android Q&A, Help & Troubleshooting] lancespahr:
If I have the Philz CWM recovery, all I need to do is flash the .zip, correct? I'm not too concerned with losing much honestly, as long as I can use LG Flash 2014 to get the device back and start over lol :) I'd definitely be willing to try it, as well as maybe a CM12/.1 based ROM when someone has one ready for testing :) (*hint hint* lol)
[Android Q&A, Help & Troubleshooting] bobdamnit:
That depends. VS880 or D631?

D631 is only confirmed back to stock from bricked 4.4.2 state. No confirmation whether it can be downgraded from 5.0.2/5.1.1. VS880 can be downgraded from any state as long as you know how.
[Android Q&A, Help & Troubleshooting] beaverslayer:
For the record, I flashed the 10b Tot file for the D631 over top of my Stock rooted 10b software. That removed all traces of root and I was able to upgrade to 5.0.2. Haven't tried to root or flash back. Considering trying to root 5.0.2 since we probably have seen the last of the updates from AT&T.

Edited to add that my phone was never bricked.
[Android Q&A, Help & Troubleshooting] lancespahr:
I have the VS880. I was on 4.4.2 10B with custom recovery (CWM Philz) and I tried to flash the 23A flashable zip... now it won't boot past the Verizon logo screen :/ any tips, or should I just revert back to stock 10B, reroot, install recovery, and wait?

**EDIT**

Tried Safe Mode boot, still stuck on Verizon screen. Still boots to custom recovery, don't have an update.zip to flash to recovery immediately since it never wanted to finish without an error :/ currently trying to wipe cache/dalvik cache and see if it helps. Otherwise I'll need some instruction on exactly how to fix :)
[Android Q&A, Help & Troubleshooting] bobdamnit:
As of now, there is no fix. Flash back to 10B, reroot, reinstall CWM and wait.

CM12.1 was a disaster. I expected a number of issues, namely WiFi, camera, and Bluetooth. However, I did not expect a dead screen immediately after boot. (Logcat shows that it DID boot, though, so that's a plus!) Soon as the boot animation is done, you lose the ability to use the touch screen. It turns on and off, but is non-reaponsive.

I'll keep plugging away at it and let you guys know when I get it anywhere near usable.
[Android Q&A, Help & Troubleshooting] lancespahr:
Flashed back to 10B, can't help but notice some things.. 1) when I booted into the 23A .zip, on the LG screen it showed the KK> android logo on bottom, not the new Lollipop-style one, 2) the LED lights up when the Verizon Logo is looping, 3) adb recognized my phone while in verizon loop screen. Just some thoughts, I'd be willing to do some testing if needed :)
[Android Q&A, Help & Troubleshooting] bobdamnit:
Are you comfortable in ADB? Can you logcat the boot and see where its hanging? Maybe I can get it working, but you got it further than I did.

---------- Post added at 05:38 PM ---------- Previous post was at 05:36 PM ----------

Are you willing to try downgrading from 5.0.2 to 4.4.2 using the TOT/DLL/LG Flash Tool 2014? That would at least confirm that D631 users have that option, should we not find a root method.
[Android Q&A, Help & Troubleshooting] lancespahr:
Absolutely, once I get home I'll reflash the rooted 23A.zip.. Should I just run adb logcat once the computer recognizes it?
[Android Q&A, Help & Troubleshooting] lancespahr:
Ran logcat on boot, seems it's not finding the correct files to finish booting (too many to name), lots of "Failed to.." or "not found" or things of that nature.. I'm not an expert on logcats so someone else will have to look through and see what's up. I'll post it to pastebin as well as a downloadable from Google Drive

[Android Q&A, Help & Troubleshooting] bobdamnit:
Most of those errors can be ignored. The issue is with ART. Its most likely not fixable. (Or not worth working on at the time.)

I just flashed 23A and logcatted the boot. Exact same errors, except it boots. Something in the way it was rooted. I'll try and perform the same root process and see if i get anywhere, but it won't be done quickly. I'm back on 60+ work weeks. :(
[Android Q&A, Help & Troubleshooting] lancespahr:
So it fully booted for you? Also, would it help if I switched to ART before flashing? I'm willing to do anything to help, I understand the 60+ hours (just not solely at work. School and other commitments) but I'll do anything I'm able to do

I recieved my insuance phone from att, and it was on lolipop 5.0.2 and i was successfully able to downgrade it to the 10b firmware with the files located here. Its great to be back in and about all.
[Android Q&A, Help & Troubleshooting] bobdamnit:
No, it didn't boot. I couldn't even get it to pick up with a logcat. You can't switch to ART, as it's built into the ROM. I got closer last night. The problem is that we need a bumped recovery (I've done that) and a bump script after flashing the ROM. I'm stuck at that point, because I cannot for the life of me get ImagePrepGUI to root the damn thing and give me a bump script.

Yes I can confirm that the d631 is downgradable with that tot and Dll files.

I reverted to 4.4 from a factory insurance phone on 5.0.2

Then I updated via fota from 4.4 to 5.0.2 and was successfully able to downgrade an fota updated version of the d631 as well.

I also reverted from rooted 5.0.2 to unrooted 4.4 and rooted 4.4 to unrooted 4.4.

And thank you my friend for the welcome :)
[Android Q&A, Help & Troubleshooting] bobdamnit:
How are you rooting 5.0.2? The same way we were rooting 4.4.2? Want to help getting 5.1.1 rooted? (I'm working on a semi-confirmed method that worked for the G4.)

Also, glad you can indeed confirm that you can downgrade from rooted 5.0.2 to 4.4.2. That means the D631 has the same brick/root protection as the VS880. Super glad I purchased it now.

[Android Q&A, Help & Troubleshooting] bobdamnit:
I have tried that version on the 23A 5.1.1 KDZ. It does let me retry multiple times, but it doesn't work. Damn.

Guess I'll go back to digging more into injecting root into the system.img and packing it all into a flashable zip. I'm running into 23A blocking Send_Command mode usage, which means I can root the system.img, however I cannot push it to the device. And without root/fastboot, thats where I'm stuck. :(

as promised I rooted the lg d631 on lolipop 5.0.2 and ran the adb logcat. Its rather long but I hope that it helps you in some sort of way. I named it as lolipop root.txt so I knew what logcat it was.

Anyway let me know of if there is anything that I could do to help further development :)
[Android Q&A, Help & Troubleshooting] bobdamnit:
I'll take a look at it tonight after I try booting the newest build of CM12.1.

Think I might have found a risky workaround for the download mode send command failure. I doubt it will work, but I have to try. Probably flash 23A before CM12.1 just to give it a shot.

I expect the touchscreen to work this time, but not WiFi, Bluetooth, data, or camera. I'll continue to keep you guys in the know, but we are still a long way off from a stable release. I haven't even looked at getting the above mentioned issues fixed due to the touchscreen being weird.

But build times are around 6 hours, so I can crack out mods and a new build once a day. [emoji6]
[Android Q&A, Help & Troubleshooting] mkfryan:
I've been lurking reading what you have been doing for a while now, I have the VS880. I am currently on 5.1.1, have you heard anymore issues with downgrading to 10B that happened a few pages back? Also I am willing and able to test if you get further with a rooted 23A or CM12.1 even just to play with as is after touch issues get worked out once I revert to 10B and unlock bootloader and get Philz touch on.

Thanks for everything you have done for the G Vista so far!
[Android Q&A, Help & Troubleshooting] bobdamnit:
No, no more issues. I've done the procedure several times and I haven't had an issue. Somehow those users did something wrong. (Used a KDZ on the D631, for example.)

As soon as I'm comfortable with the build being tested, I'll drop PM's. I definitely need a D631 tester, as I do not have that device. I just logged into my home computer and it's done. I'm just waiting to get home to test the build out and see if it fixed the touchscreen. If it did, I'd like to send it out to a D631 user tonight and have them test it on their device. If it didn't, well, then I don't know.

I was farting around today at work, and my send command mode fix just isn't plausible without root. So, I'm shelving the root idea unless someone can come up with an alternative. I'll focus on CM12.1 because at this point we all have a way back to rooted status and a mostly working custom recovery.

Be patient with me guys. I haven't built a ROM since I had the LG Optimus M for MetroPCS, and we we're trying to build CM7. Its been that long. :(
[Android Q&A, Help & Troubleshooting] mkfryan:
Thanks for the fast response!

Thank you for your work with this it is really appreciated. Take all the time you need! I haven't been a much in dept tester since the LG Optimus S days with TheKraven and a little bit with LG Marquee with TDM and Bloodawn, however always willing to do my contributions. If there is anything you need, just ask I'll do what I can.
[Android Q&A, Help & Troubleshooting] lancespahr:
I'm also willing to do anything and everything I can to help out :) thanks so much for everything you've accomplished so far :)
[Android Q&A, Help & Troubleshooting] bobdamnit:
It doesn't boot. Like, at all. Logcat says display module issue. So, that build was a total failure. I'm going to just delete it and go back to the booting one with touchscreen issues. I'm going to flash it real quick and see if the display is totally screwed or if maybe certain areas work. I don't know, I've never run into this before and mostly anything I can find is for the OnePlus One.

It may be that I have to build CM12 before I can do 12.1. So I'll start a build for that while I play with my useless phone. God I'm glad I have a nandroid of 4.4.2 rooted. It makes getting back to a usable phone much easier.
[Android Q&A, Help & Troubleshooting] lancespahr:
just curious, how difficult is it to build CM? would it be helpful at all for multiple "variations" to be built for testing, or would that just make things worse/more confusing?
[Android Q&A, Help & Troubleshooting] djacks222:
[MENTION=4427107]bobdamnit[/MENTION] check your pms. I'll test your product and I do have the d631.
[Android Q&A, Help & Troubleshooting] bobdamnit:
It's more difficult setting the environment up, but once you have that setup, it's very simple.

The hard part is changing things to work with the LG source code files. I don't have the board source code, only the Lollipop source files. As such, I need to modify CM12/.1 to work with their proprietary drivers. Not an easy, fun, or short process.

Building two different versions of a ROM is as simple as making a directory structure for each ROM, pointing your environment towards the ROM structure you want, and making the ROM. If it's done properly and no errors occur, a ROM will spit out in the build directory for you to flash. Keeping track of them is as easy as remembering which was modified and built last.

But I can build CM12 at night and test at work while CM12.1 is building all day. Between the two, my desktop computer is gonna be running a bit warm and sucking up the wattage. [emoji106]
[Android Q&A, Help & Troubleshooting] lancespahr:
Say I figured out all the details, set up an environment, and started working on either CM12 or CM12.1 (or anything else for that matter), would that be more of a pain, or would it be beneficial? I figure it might save you some work (as long as I do it correctly lol) and time, and possibly get things done quicker? Idk just a thought, I'm happy just being a tester once things are semi-stable :) put me to work wherever I can be useful

I was able to get Philz touch installed without blasthing LAF partition, will that hinder me from being able to boot CM?
[Android Q&A, Help & Troubleshooting] bobdamnit:

Care to explain how you achieved this? (I haven't quite figured Bump out yet...)
[Android Q&A, Help & Troubleshooting] mkfryan:
It was a one click that I found right after I got this phone in July. I had it saved on my laptop. I will try to find the link for out so whoever made it is credited before uploading it.
[Android Q&A, Help & Troubleshooting] lancespahr:
So you have the custom recovery as well as download mode (not fastboot)? It shouldn't be a problem, but if I'm reading correctly that isn't a difficult state to be in, just use fastboot to flash recovery then re-flash your laf partition.. Are you able to upgrade to lollipop and keep custom recovery, even without root?

Sent from my SM-N915V
[Android Q&A, Help & Troubleshooting] bobdamnit:
No, it's not difficult. But to be able to install a custom recovery without root would really help out rooting 5.1.1. Just flash a root script in recovery and be done with it.

That would be awesome.
[Android Q&A, Help & Troubleshooting] mkfryan:
I ended up blasting LAF just because. When I first got the phone and had download mode with PhilZ touch, soft bricked from OTA to 23A. I'm not sure if I can use the 23A kdz and keep PhilZ. Tonight I will go back to 10B stock rooted with download mode and cwm. Should I try to flash the 23A not using CSE flash and see if it leaves the recovery in place?
[Android Q&A, Help & Troubleshooting] bobdamnit:
It won't. I was hoping you had a way to get CWM recovery without root. I didn't think you had, but it was worth asking.
[Android Q&A, Help & Troubleshooting] lancespahr:
would fastboot stick around through an OTA? if so, is root required to flash a recovery .img? Probably not, but I figure it's worth a shot even if there's a 1% chance it works
[Android Q&A, Help & Troubleshooting] bobdamnit:
No, if you have wiped the laf to enable fastboot, you cannot take an OTA update. If you use a KDZ or a TOT, it will replace the laf.

Root is required to wipe the laf partition to enable fastboot. You cannot flash the recovery partition without fastboot, so yup. Its required.

The best you could hope for is decompressing the KDZ/TOT (which I have done) and creating a flashable zip of 5.1.1 from the contents. It doesn't even have to be rooted because we are going to flash it in a custom recovery anyway, so we can root it later. This was attempted once, and nobody could get it to boot.

Its taking me forever to pull CM12 from home to work, so I'm just gonna wait until I get home to try it. I have no expectation for this build, other than I'm prepared that it will not boot. If it does, I'm already doing 100% better than I thought I would. :)
[Android Q&A, Help & Troubleshooting] lancespahr:

[Android Q&A, Help & Troubleshooting] bobdamnit:
Find a way to bypass security checks. I have no idea how to do it, or even if it's possible. It could also be that certain partitions need to be flashed BEFORE system.img gets flashed. (Recovery and laf, for example...)
[Android Q&A, Help & Troubleshooting] lancespahr:
GOT IT!!!! :D I'll post method in a bit, but from the looks of it, we have successfully achieved 5.1.1 root :) or at least a roundabout way of getting there

**edit**

There is an issue with the modem, I'll work on it tonight. But hey, its rooted 5.1.1 :D
[Android Q&A, Help & Troubleshooting] bobdamnit:
The previous user that tried this also had modem issues. He claimed to have fixed it by using the 4.4.2 modem. (I don't currently remember if it was 10 or 11B modem.) Sadly, nobody could get his flashable zip to boot, nor could we get his rooted 23A nandroid to boot. :(

But if you have a usable rooted system.img, we can manually flash the KDZ or build a flashable zip for custom recovery. Then, we try and modify the 23A KDZ for the D631. [emoji6]
[Android Q&A, Help & Troubleshooting] lancespahr:
Yeah, once I get home I'm reflashing 23A modem, if that won't work I have 11B modem, and hope that works. I have the system.img, but it wasn't rooted. Just stock from the 23A kdz. I'll explain more in depth once I get home (idk if I should start a new thread for the root for 5.1.1 or if that's unnecessary?) I had to bump the boot.bin with a zip, which is what made it boot. I didn't flash the entire kdz, only specific parts.
