I upgraded from a stock rooted 4.4.2 to the OTA 5.0 using the ROM that was rooted. Some apps for my smart watch don't work in 5.0 yet, so I went TWRP and restored my backup. After booting, the phone will not get any service at all. It shows it's searching for service then gives a red "x" then starts searching again. This is process that just keeps going. I flashed the stock .tot file using the LG flash tool to get the phone completely back to stock. After doing so, the radio still won't get service. I then applied the OTA push of 5.0. After 5.0 was installed, the radio gets service without any issues. I used the LG flash tool again to go back to 4.4.2 stock and same issue; no service. Updated again to 5.0, and I get service. Any ideas on what's happening here? Is it the firmware for the radio that's having issues?
I was able to fix this by playing with the APN settings and it was able to get service, but no data. I then went back to the default t-mobile APN setting and now it works.
Same Issue
After using lg update tool to go to new 5.0 update, I put twrp back on and flashed cm12 and bliss pop rom on mine and service 100% drops out and only came back after a battery pull or a reboot, e tried to re-install roms on both and after having the same issue with the roms i tried a custom kernel issue went away and then came back, so i haven't tried AOSP since the t mobile said they'd send me another brand new phone ....but once i put everything back to OEM using the lg tool it's been 100% working again with no issues... i will try AOSP when the new phone gets here,, im thinking its kernel related
You need the new modem, boot loader, and boot images. You can't simply just flash a ROM unless all 4 (system included) is packaged as so

My phone decided to stop getting a connection today[1], and since I'm running CM11 I figured I might try flashing back to a stock ODIN package. Is there anything I need to be aware of in terms of going back to CM eventually (bootloaders/modems/etc)? I remember when I first got this phone there was some confusion about bootloader versions, but I'm guessing if I flash a stock Kitkat ROM it should be okay with CM11? Thanks!
[1] I get a signal, ~ -75dBm, but no connection, and the same SIM works in another phone.
Hello friends. I need to explain this problem:
When I bought my phone for the first time, I remember when I made it a full wipe from shortcuts on the phone's buttons, LG applications are maintained.
Now after having rooted my phone, installed TWRP and have installed several roms, I have decided to re-stock with KDZ.
But the problem is that after having flashed the KDZ, LG applications has disappeared.
I'll put screenshot after performing a restore kdz:
***SOLVED***
Flashing original TOT Firmware contains complete firmware.
KDZ not contain all firmware.
I had a similar issue as yours back on my Galaxy s4, except it was the carrier apps (bell) that would be missing, and I also wouldn't get the "LTE" icon after a stock firmware flash if I was going from a rom that didn't already have the icon (weird I know).
Anyways I was able to fix the issue by doing a SECOND flash EVERYTIME I went back to stock rom.
I flashed 100's of times on my s4 and EVERYTIME I went back to stock I had to do 2 flashes or I would have "missing apps"
I never had this issue with my g3 yet, but I haven't tried to go back to stock yet since changing to cloudy rom.
I don't know if this fix will work for the g3 like it did on my s4, but it can't hurt to try.

exactly this happened to me when I try to install the ROM Cloudy, when I want to go back to stock with kdz, the LG system applications disappeared.
My question is this?
The KDZ not come with these pre-installed applications?
It is out of reach of KDZ, it will be in another folder outside SYSTEM.
It's strange, now my question is that will not see problems in an OTA update.
LOL, that strangest problem. :silly:
Solved Mystery...... Flash TOT contains complete stock firmware. :good:
KDZ not contain all firmware.
Can anyone help with this. I have a sprint note 4 that I rooted and was working great, but wanted the stock 5.0.2 upgrade. Used odin to install stock 4.4.4 and remove root. Worked fine phone took the 5.0.2 upgrade. Rerooted and installed wifi tether router but could not get it to work, found it is not working on 5.0.2, dam. Used odin once again to return to stock 4.4.4, rooted, installed wifi tether, everything works with one problem. When turning the screen on I now have a severe lag between the button push and the screen light up.
I odined back for other issues and still had problems. .even a backup was not working... i wiped everything, all data etc, 2 times then went back to nie....then took the otas back to lollipop. .now everything works fine except i still hate the colors

Fixed, it was a bad sd card had nothing to do with the dowgrade.
Good to hear you found your problem. However if it's tethering that's keeping you away from Lollipop then you can put that to rest because you can easily enable wifi/usb tethering without the need for a third part app like tether router (which i have payed for as well). If you expect to stay on the factory rom/firmware then Lollipop would be a wise choice due to the new ART (android runtime) and it's overall effeciency compared to KK . It has a lot of benefits and other than the stock colors, there's no reason you shouldn't update to Lollipop. Do a little searching here in the Sprint Note 4 forum and you'll find a few easy ways to enable the built-in tethering.
Thanks for the info, did exactly that, found galaxy tools would provide the tether

You are SOL for now. Cant downgrade rom OE1, but a new OTA is about to come out, I'd sit tight until then. or...Many people flash Noterized Rom. Try flashing that and continue your troubleshooting.
Stuck
Here is my screen
Well, I followed an XDA thread to SIM unlock the M919. It involved downgrading from 4.4.4 to 4.2. and I successfully unlocked my device! But now I have no Wifi... I tried flashing every single modem, every firmware (Official TW ones via Odin, every custom rom using TWRP). They flashed well and everything worked besides the Wifi. I've found some threads from people with the exact same problem (they tried to unlock it using the same method) but those are old threads with no solution.
I've spent 24hrs reading and flashing and wiping and reading again. Any ideas?
Many thanks!
Anyone? If you find me a solution I will Paypal you 20 bucks!

I am having the same issue. My phone was already unlocked though, so no downgrading on my part, but I think we're having the same issue. Is yours showing connected, but usually getting time outs or disconnecting?
My issue happened when I flashed from stock 4.2 to the GPE rom for 5.1. Wi-fi issues. Connected, but exclamation point saying that my connection wasn't working. So I flashed a different rom (candy) and still, I have issues. So I went back to 4.2, stock everything. Stock bootloader, stock rom, stock radio. Still had issues. So I decided maybe flashing a new radio would work, so I flashed NH7 and NK2 (broke my audio). Still didn't work. Realized my bootloader doesn't match the modem, so I flashed 4.4.4 stock bootloader and stock NK2 modem. Tried it with the candy rom. No go. I tried the 4.4.4 stock ROM, wifi still has that stupid exclamation point. I've even gone so far as flashing both the bootloader and the radio over 5 times in one go (with battery pull each time) to see if that will work (starting to go nuts, I guess), but still, no fix.
I've had a temporary fix with Tasker (Connect2wifi), but it doesn't work when my phone is on idle, so I don't get any notifications until I actually wake up my phone.
I'm starting to wonder if it's the physical wifi radio (antenna) inside my phone that's broken. But then I wouldn't be able to connect at all if that's the case, right?

No, unfortunately my issue is very different. I know it isn't hardware related. I've never had any issues with it until the second I downgraded. Wifi just doesn't turn on. When I click on the button it just tries to turn on and after a couple seconds it turns back off, without even detecting any networks. This happens no matter what rom, version of android or modem I use. Downgraded, upgraded, tested every single modem and rom via TWRP and Odin.

Hello guys,
I managed again to brick my phone.
I flashed Fulmics as I wanted to swap from those not fully stable nougat roms. Well, I have no idea what caused my problem - Fulmics run without prolbems for a 2 or 3 days including xposed etc.
Then today I changed my ChromePie options and that's when the reboots began. I don't know if this the real cause was though.
So I tried to flash another rom but always got random reboot even in recovery after few minutes/seconds. So I went all the way back to stock rom (4.4.2) with LG Flash tool - which worked after a few tries. Then I installed MM rom via .kdz file and flash tool 2014, which also worked after a few more tries. But then the reboots started again. Can't say if the 4.4.2 rom was without boots because I updated to 6.0 quite quickly.
The strange thing is that after some reboots phone won't boot again and I have to take and leave out the battery for some time to boot the phone again.
Any solutions for my problems?
Best regards
..bumped into the same 1/2 year ago. Didn't want to put to much effort so,..went to stock and back, worked for me.
Good luck.

Which stock and how did you go back?
As mentioned I already went back to stock but the issue kept occuring.
Hi, got the same problem with my G3
wi fi and bluetooth didn't work and phone loop rebooted
Here below the steps I followed to solve
1) First attempt (didn't solve): had cloudy rom, got back to stock official but still rebooting, tried fulmics and other rom but problem persisted.
2) second attempt (didn't solve): went back to stock and changed battery (found somewhere in internet), now I have a brand new battery but a phone still loop rebooting
3) third attempt (SOLVED): found that the wi-fi / bluetooth chip (one for both) copuld have unwelded and solved so (it appears I can't post outside link, delete spaces to have the correct link):
youtube .com / watch?v=1zWpzYh2DPI&t=15s"
youtube .com/ watch?v=6_0jzp65eLY&t=256s
Now i'm on fulmics and no more loop reboot
Hope you can solve
[sorry for my english]

used flashtool
have to say restoring and/or flashing isn't always that stable. I've experienced it sometimes needs a 2nd try.
Hopefully it isn't a hardware issue in your case.
So I tried all of oyur suggestions but nothing seems to work.
On the contrary I ended up in a status where I can't even flash a new firmware.
In LG Flash Tool 1.8.1 I get the error
"Donwload Fail!!!"

In LG Flash Tool 2014 (flashing MM with kdz file) phone shuts down in middle of process.
But I can still access Download Mode.
No more ideas?
I really think I finally broke my phone... But the fact that I can still access download mode keeps my hopes up.
So, after 2 months I just tried to reawaken my phone. Still the exact same problem. It just keeps shutting down aber some while, but just when I start flashing something. If it stays connected to computer whitout doing anything it can stay on for like ever.
Can anyone confirm that this could be a hardware defect?
