[Q] LG G3 not working at all after root - G3 Q&A, Help & Troubleshooting

Hey guys I really need your help with something! I recently rooted my LG G3 using stump and downloaded an application that needed to restart my phone so I did and now when i try to turn my phone on all I see is the LG load screen but nothing will happen after that. The LED continues to flash at the load screen, but it wont go anywhere. Also, I have tried to wipe cache, factory reset, and apply updates in the recovery area but nothing seems to work. I have also tried doing a factory data reset but like everything else i can only make it to the load screen. This is the first device i have ever rooted so I am very new at this but I really need some help!

Sounds like the app did something malicious. What app?

I would like to make a suggestion for you and for other noobs planning to root and mod their devices.
Firstly every single person whom ever tweaked their device flashed custom ROMs, Kernels etc either has or will need some help at some point.
The most valuable point that I can stress is this, before you root, find out how to undo it and how to fix or troubleshoot different senarios.
If you see the LG animation then this means you have any number of ways to fix the issue(you're not doomed), check the tutorials, do some reading and search its all here, you managed to find out how to root etc so now do a little more to find out how to fix, good luck.

Can you enter download mode?

My phone sometimes crashes, how can I rule out a software issue?

Hello everyone,
First of all my problem. Since about 2 weeks I started getting random crashes. The phone is unresponsive and the screen goes from really bright to a greenish/grey color (hard to explain). I googled but I didn't find an answer. If anyone here knows the problem that'd be great but I doubt it since there are so many this that could cause this. So now my question is, how can I be certain it's not an software issue? Further info: My phone is rooted, and I didn't change the ROM. However, I don't actually have root permissions and when I open SuperSU it asks me to update the binary which always fails. I tried to Root it again with the Galaxy Toolkit and it says it's already rooted. Also, Under the google logo is a unlocked lock sign.
Thanks
I would recommend you to try some custom stable ROM, based on 4.1.2. CM, AOKP are among top ones.
better make a backup using recovery, and flash a new ROM. It will give you a fresh start with SU too.
If you dont like using a custom ROM, restore an earlier backup if you already have..

My only expercience with custom roms got me into a boot loop, so I don't prefere that. I actually want a "out-of-the-box" phone without any modifications. Therefore I tried a factory reset but that keeps the root and unlock.

ok, if you want to get the total old look, relock the bootloader, and install official GNex image that comes straight from Google. Hope this sorts the issue out.
Yes, Custom ROMs are a bit time taking to setup in the start, but thats the whole point - a lot of options. I flashed alot of ROMs and luckily, I have had no boot issue still. I think following the proper instructions(which are simply wiping and formatting data, cache, and dalvik) are easily gonna keep the boot loops away.
You can rule out a sw issue by starting fresh.

LG G3 "No OS Installed"

Hello I have not been here long but anytime I need help with something pertaining to a phone I come here.
So here it goes. I got an LG G3. I got root then I installed Bump'd as it was released. I then installed a custom rom and all seemed to be good. A few weeks later my phone got stuck on TWRP custom recovery. I managed to get that fixed by finding a thread on this web site. Now I was going to install candy rom from the Sprint LG G3 section but as I wiped Cache and all that other good stuff what ended up happening is that it may have wiped something it should not have . Because now the phone will now only boot to TWRP, and it keeps informing me that "No OS is installed."
Now here's the tricky part. It doesn't seem to want to go into download mode either.
So all I can do it TWRP.
So I have two questions
1. I heard that you could possibly put some sort of file on an SD card and flash it on TWRP to fix it. Is this true ? If so, can someone direct me to how to do so with instructions?
and
2. If #1 does not work... does that mean that my phone is screwed and there is nothing I can do with it at this point ? I have soft bricked phones but never something like this.
Help anyone as I would like to get this fixed ASAP if there is some way to fix it.
Please and thank you!

Freegee app for OGP not working

Hello people, I don't know if there's anyone out there who still uses the G pro but here I am still using it. Okay so I have been stuck with this problem for almost 2 months now, I rooted my phone amd everything was great till the time I tried to install a custom recovery using freegee. It did not work. In the beginning, it said my phone wasn't compatible because of some loki thing but I still went ahead with it anyway.
So after I installed the 2nd-init recovery, after I rebooted, things went bad. My phone was okay, sort of. The main problem was that my memory card stopped working and my phone began changing settings itself like turning the wifi off, screen on changes to 15 seconds and it keeps doing this again and again and I have to keep changing the settings.
Can somebody please help me fix this issue as I really can't take this anymore. I cant use my phone properly any longer. Oh and my phone is still under warranty but m scared to give it in as I feel they might find out it was rooted. Is there anyway I can get back to the old recovery and remove this 2nd init file? i can locate the file bt im scared to delete it as i wouldnt wanna wreck my phone any further.
Any help would be appreciated.

Restore to stock first. 2nd-init recoveries are very hard to remove without extensive knowledges on linux shell.
They you can re-root the phone. If your phone supports the 'LG Support Tool', then use it. It will recover your phone to stock in clean and nice GUI.
I tried the lg support tool. It just keeps stopping.
I'm not really good at this. I restored to stock by performing a factory reset but Im just lost at this point. Can I give it in for servicing because its still under warranty?

Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck
I don't know about lg support tool, but the best thing will be use lg flash tool, there are many thread on how to flash the img files. You can flash the recovery that way. Or you can flash your device back to stock rom 4.12 which is the best starting point.

[Q] Broken Wifi - Can't be turned on/off - No List

A lot has happened to my g3 over the last week.
Including rooting it, flashing a custom recovery, flashing a rom, soft bricking it, almost hard bricking it, and then recovering to stock again, and then finally recovering my stuff with the LG recovery tool. And now everything works except for the WiFi. When I turn it on nothing happens, except that I can't turn it off again. It also doesn't show on the notification bar. I tried an app called Wifi Manager. No luck.
Basically the question here is: What's the best way to find out if the issue is hardware or software related? I would be willing to flash it now that I'm more experienced with the matter. But only if it yields results.
Appreciate any help.

Just to be clear youve done a CSE Flash right? Not just restoring a TWRP Backup?
Have you dropped the phone?

Sorry should have closed the thread already.
I did do a CSE flash and flashing a new ROM did solve the problem. Seems to be a pretty rare compatibility problem.

Bootloop on LG G Pad II 8.0 LTE (V497)

Hi!
Little background: I've had about every Nexus device that has been released and I've rooted them all, changed all their custom recovery, installed XPosed and fiddled around with ROMs all manually using adb and fastboot (never used a 1-click tool). Of course this is all relatively easy, since you can just go back and flash the original image if you mess something up.
Problem is, I messed up the LG G Pad and I'm kinda stuck. What I did to mess it up:
- No way I'm going without root and there's no way to flash a custom recovery
- Install Kingroot apk, ran it, got root
- Install supersu-me to remove kingroot and replace with SuperSU (the one I usually use and install via a zip in custom recovery)
- Reboot device....bootloop
- Find out the magical sequence to factory reset, do it
- Same bootloop
So it's now just stuck at the LG Life's Good (no it's not!!!) and I can't seem to be able to get adb to work anywhere, I've also gone into download mode, but I can't do much in there.
I'm open to all suggestions
Solution found?

Sadly my solution was to send it back. I said it stopped working after a Factory Reset, which isn't totally false. They accepted the RMA and I'm not going to root the new one I received.
Got stuck on my 495. Unfortunately I bought it second hand so I don't know if they will warranty my repair. err.... I'm hoping to find a solution. Did you ever try the LG Bridge software? I've had no luck with it.
PHP:
Hello. To root an lg-v497 simply use the mobile go trial on pc. To reset the tablet if it is in a boot loop simply use the lg support tool. You need to install the v500 driver for it to connect to the tablet. Factory reset will not fix it. You must re-flash firmware in this way.
Of course this may not be of use to many but it is what i have found works best. Hope this helps somebody. I went through that exact same scenario as you did, OP, and that is how i solved it. BUT now i am trying to find a way to crack the bootloader because i want to fix or get rid of 5.0.
Any Chance you could put links to the support tool and the driver? If I have KingRoot on already, should I restart or just uninstall before rooting with Mobile Go?
My account is apparently too new to post the links but just google the lg mobile usb driver and go to lg support page for the tool
To do a fresh flash you go to update recovery in the top menu when connected.You may have to fiddle with it a bit, good luck.
Flash it before using mobilego. Kingroot is a plague and you should get rid of it first.
