[G3 Q&A, Help & Troubleshooting] Drake Maijstral:
I recently picked up a D851 (TMobile). I rooted it, but did not replace the ROM or install a custom bootloader.

Last weekend, the phone started randomly rebooting. Watching logcat via adb showed me several random apps throwing sig11s, after which the phone would give up and reboot. Cycle repeats.

This looks like a hardware issue, as the apps that crash change on each boot cycle.

I arranged with TMobile to swap the device, but they cautioned me that the phone must be returned to an unrooted state.

I've had a hell of a time with it from here. My first try was to install the LG drivers and the PC Suite under a Windows VM, as I do not run Windows at home. Enabling USB passthrough for the phone to the VM let Windows see the phone, but the LG drivers would invariably fail with 'Device cannot start. Code 10.'. Likewise, the PC Suite couldn't find the phone.

Next step was to throw together some spare hw and install Windows 7 on that (a desparate move, to be certain. :) ). The LG drivers can now recognize the phone, so that's a definite plus. The LG PC Suite, though, claimed that my phone could not be upgraded. Wonderful.

Next step was to try this tutorial: http://www.androidrootz.com/2014/07/how-to-unroot-lg-g3-all-variants.html . I was able to get further with this method, but as it begins to flash SYSTEM, it pauses, and then dies with 'We can't communicate with Phone'. End result - I now have a soft bricked phone. On the phone, I see the port - COM41 - appear, and the usb animation starts to spin ... and after a few seconds, stops. It's at this point that Flashtool throws the Can't Connect error.

I next tried following this tutorial: http://xdaforums.com/showthread.php?t=2785089 to flash a KDZ. The newer LG Flash tool used here can't create a connection to my phone for flashing.

I've run into a wall here. Any ideas on where to go next? I need to reset this phone back to a working stock state so that I can send it back.

Didn't find the similar question here. hope anyone can help to answer.

the bootloader is unlocked and system is jb 4.1.2. I want to update to kitkat and keep unlocked BL.

I have downloaded the rom VZW_XT907_4.4.2-KDA20.62-10.1_CFC_1FF.xml.zip

is rsd flash ok, or is there a fastboot way to update anything like system, radio, recovery except BL to kitkat?
[Droid RAZR M Q&A, Help & Troubleshooting] Klen2:
Update everything. Once unlocked, your bootloader can't be locked, so you are safe. I recommand you not to try to flash only some parts. It should cause hard brick (something similar happened to me).

[Nexus 9 Q&A, Help & Troubleshooting] hdad2:
Am I the only one thinking that this tablet with pen support would be killer?

Nexus 9 has K1 processor. My understanding is all the DirectStylus 2 magic in the Shield is software set to take advantage of the K1 and touchscreen. Anyone have a guess how deeply integrated that is, and if it could ever be ported to Nexus 9?
[Nexus 9 Q&A, Help & Troubleshooting] jcracken:
This is something I'm really hoping for.

Sad thing is that most likely if it isn't part of the stock software then best case scenario is someone porting it over (probably while porting over the other Shield Tablet stuff, such as GameStream) but usually stuff like that happens once and then gets pushed aside when the original developer gets bored with it/jumps to a different device/doesn't want to put in the effort to port it up to a new Android version. Good example of this is Flash on iOS, it was a big deal for a while then everybody kind of got tired of it...

[8125, K-JAM, P4300, MDA Vario General] vijay555:
What are you trying to do?

Soft reset - poke your stylus into the hole that is somewhere on your phone.

Hard reset - search the wiki (I don't have your phone) or use the clear storage application.

VJEschaton will also do the same thing, but you shouldn't need it.

Q&A for [FIX] Stuck in Custom Recovery [TWRP/CWM] (After trying OTA)

Placing your question within this thread will increase its chances of being answered by a member of the community or by the developer. Thanks for understanding and for helping to keep XDA neat and tidy! :smile:
[G3 Q&A, Help & Troubleshooting] skylar21:
Hello, I tried to update via OTA and I have TWRP installed, after applying the update, I'm stuck at recovery. I have searched google for answers and found this :

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc

Type in this codes in TWRP Terminal. After that, I was able to get pass through TWRP, and my G3 has not been updated.

Now the problem is:

1. When I checked my MAC Address, it has changed, same with my SW Version which is from V10i-ESA-XX to V10i-GLOBAL-COM

2. I tried to update via OTA but it tells me that I have already installed the latest version.

3. I have flashed a KDZ file based on my IMEI but the SW version is still GLOBAL, the MAC address too is not my old MAC address anymore

Help ? :)
[G3 Q&A, Help & Troubleshooting] nolanpen:
Same Here, stuck in TWRP, flashed thru flash tool online via recovery using IMEI and SW version is now in GLOBAL.

I think i successfully flashed it because the powered by ANDROID in boot logo is now bigger than V10i.
[G3 Q&A, Help & Troubleshooting] skylar21:
I, too, have flashed the latest kdz file, and the update is applied. Hopefully someone can help us
[G3 Q&A, Help & Troubleshooting] nolanpen:
I'm not sure if it matters, it's really an official firmware though changing region.

Functionalities are not affected with this, I'm sure we would still be getting update in the future.

[G3 Q&A, Help & Troubleshooting] 911jason:
My phone was working fine yesterday morning after work. I turned it off and plugged it in as usual, but when I turned it on tonight it booted straight to TWRP. I tried rebooting and it did the same thing. I restored from a previous nandroid backup and it still will only boot to recovery. I had blocked updates, but now that I'm thinking about it, I may have restored an older backup a few days ago that didn't have them blocked.

I was already planning to un-root and flash back to stock for another issue I was having, so I've got those files on my computer ready to go, so I'm just going to go ahead with that. I'm just wondering what could have caused this.

Ok...wtf just happened? Went to bed...all was fine. Alarm woke me up...2 hours later I woke up and the phone was stuck in twrp.

Thank god for these instructions, but I bad disabled ota from the dialer, froze lgota in titanium? How the hell did this happen?

The only thing I can think is i too went from stock to cloudy 1.1 then back to a nandroid. My nandroid may have been before I disabled ota.

Next question, when I go to phone status and update, my phone says continue update. I used root explorer to /cache/fota and did have some ota files in there. I deleted and reboot,however the status stills says continue update...how can. I reset this and make sure to prevent this sneaky update from happening again?

[G3 Q&A, Help & Troubleshooting] 911jason:
Find the unroot instructions for your model, the method I used for the D850 doesn't use recovery, so I would think that would work fine for you. Then you can re-root and start all over fresh.

Hi,

After upgrading my LG G3 to lollilop, I got stuck in recovery ( like described here : http://xdaforums.com/lg-g3/development/fix-stuck-custom-recovery-trying-ota-t2907508 ).

What Worked For Me

Data ON seems to slow down WiFi! Test your speeds with data ON and then with it OFF. If you find data ON slows down WiFi, do the following.

You can install a Data On/Off widget on phone and keep it off while home or someplace want or need WiFi. Turn data off and test WiFi speed. If it's fast again, then you either need to remember to turn data back on by tapping the widget when you leave home (or wherever you are with WiFi).

A trick I use is to install an app called "Trigger" and set it to:

Away from Home / Actions / Enable Mobile Data.

Home / Disable Mobile Data. It all happens automatically and works great.

My Galaxy S5 did the same thing!
