Thanks so much for these!

Stupid question: This is for the US T-Mobile device, right?

What would be the steps to pull these files manually from our own devices (if it's not too much to ask)?

Yes, this is T-Mobile. I would recommend just using TWRP for backup. However, if you're more interested in pulling it manually, you have to do a bunch of adb shell commands and figure out the partition structure and then dd the img's. We made these before TWRP was functional, hah.

The offical version. But it breaks the second screen.
Can you test WiFi Calling please? Xposed breaks it on the G4, unfortunately, I wonder if it breaks it on the V10, too.

Put the phone in Airplane Mode, enable WiFi, then enable WiFi Calling. Does WiFi Calling get stuck on "Enabling" and then after a long time (5-7 mins) times out with "REG99: Unable to Connect"? If so, Xposed breaks it as well. (Note that if you have LTE signal, strangely, WiFi Calling works, but as soon as you lose LTE, it dies, so do not test with the cellular radio on).

Have you actually tried this without being rooted? Or having Xposed installed? I'm pretty sure wifi calling NOT working with airplane mode on is not a bug.

Instead of arguing, could you please do the test?

Yes, this is a very well known issue. On a stock, rooted G4, WiFi Calling works fine in Airplane Mode. It also works in Airplane Mode on my Note 4. That is how it is SUPPOSED to work. The whole purpose of WiFi Calling is to give you phone/SMS connectivity when you have no cellular signal.

We have figured out the issue only happens when Xposed is installed on a stock odexed ROM. If you deodex the ROM, it works fine with Xposed. The problem is deodexing LG ROMs breaks many features since some APKs cannot be deodexed, so we are waiting for rovo89 to fix it.

We have a thread about this issue: http://forum.xda-developers.com/tmobile-g4/help/wifi-calling-errors-10n-update-t3191362

And it has been logged as an issue on rovo89's github: https://github.com/rovo89/Xposed/issues/66

Now, can someone please do the test for us?

I did the test, it does break wifi calling with airplane mode on. I don't think I've ever been anywhere I didn't have some sort of signal with T-Mobile so I would never have noticed. I've never used airplane mode either. What features does deodexing break? Are you sure people are deodexing it correctly? I'm one of the first people to successfully deodex arm64 so I know it can be a pia.

Thank you for confirming.

Just because it has never happened to you, it doesn't mean it doesn't happen to others. In my basement, which is my entertainment room, I have no cell signal from any provider, so WiFi Calling is a must. I'm sure there are plenty of other scenarios where you would not have any cellular signal at all but have WiFi.

I don't know what "correct deodexing" is, you can ask the guy who did it. Some APKs are still odexed and some apps are force-closing in his deodexed base: http://forum.xda-developers.com/tmobile-g4/development/h811-deodexed-base-installer-t3219382

If you could tell us how to correctly, and 100% successfully deodex an LG ROM, we would be very grateful!

I will grab the stock system dump and deodex it. Hopefully It's an easy fix.

Deodexing threw 2 errors, one for easyhome and the other for weather. Neither of which should cause major issues. If I can just get the updater script figured out we'll be in business. Missing symlinks...

Grrr. You're right, LG IMS fc's as well as the weather app i expected. That's all I have fc'ing ATM, I'm hoping for an easy fix.
I got around the fc's. Deodexing fixes the second screen, although I can't get wifi calling to work at all.

Make sure you have the newest fastboot binary or it won't flash the system.img
Link for newest fastboot binary?

---------- Post added at 07:41 AM ---------- Previous post was at 07:00 AM ----------

These are stock .img files that we pulled once TWRP got booted. If you break something (like flashing TWRP incorrectly), you can use these to restore it.

boot.img - https://drive.google.com/file/d/0B5fMrmukgO0NcVdKYzczRFBBSlk/view?usp=sharing
recovery.img - https://drive.google.com/file/d/0B5fMrmukgO0NUTUtdXdVZTM5MGs/view?usp=sharing
system.img - https://drive.google.com/file/d/0B5fMrmukgO0NcTYxVHhkSkxfelk/view?usp=sharing
Has anyone actually tried flashing these? I flashed all 3 using fastboot with the latest binary & my V10 might be bricked now

I would recommend flashing the zip I posted rather than flashing the images. You're not bricked. Flash twrp again then adb sideload the zip I posted.

I can't find the zip you posted in this thr4ead mikeyinid ?? Please post again...
Thanks!
It's in it's own thread here in the dev forum.

I just tried every version of fastboot I could find to flash the system.img and it's just to large. @TheJesus I think it may be a good idea to edit the OP and remove the system.img. People looking to go back to stock can flash the zip I provided HERE

I didn't add the recovery.img to the zip although I could. That way all you'd have to do is flash the zip in recovery and your device would be 100% stock. Eliminate the need to fastboot the recovery.img afterward...
