I've been rooting my phones since getting my first HTC Incredible, so while I am certainly not an expert, I have a bit of experience researching rooting methods and roms and flashing and recoveries before getting my hands dirty. Now I'm in over my head.
I've had my G3 rooted since December, but kept it on the stock Kitkat rom until yesterday. I flashed TWRP and then HolyAngel's Skydragon G3, going with the Lollipop version along with the Skydragon kernel.
Booted up just fine, but my data kept dropping out. The lock screen message would constantly switch from "Verizon Wireless" to "Service disabled" every few seconds. Connecting to WiFi works just fine.
I've tried reflashing Skydragon, both Lollipop and Kit Kat versions, Skydragon kernel and stock kernel. I've tried flashing the nandroid backup I made before flashing Skydragon the first time. Each time the data connectivity issue has persisted. Calls and texts are out of the question and as a nice added piece of frustration, I can't log into my Google account now because I have 2-step verification turned on and I can't receive texts.
What did I do and how do I fix it? Help please!

Try flashing the 23b modem again: https://www.androidfilehost.com/?fid=95916177934538781
I think you can only use the 23B modem for SD or Jasmine LP - anything else causes what you have going on. Also check your network setting and set it to LTE if it is set to global. Good luck.
Thank you! So to clarify, if I reflash the 23B modem zip file I'll need to be on either the Skydragon or Jasmine roms for my data to be restored?
I ask because I'm back on my (rooted, stock) nandroid backup, so if that's the case I need to reflash Skydragon first correct? Would It work with the kitkat version of SD?
Thanks again!

Yup, the 23B modem is for stock based Jasmine/SD lollipop ROMs, and the 10b/11c/12b modems are for KK (and AOSP) ROMs. So to clarify: if you're on SD KK right now then 12b is the most current modem you should use(ends in...7834.1) & if you're on, or plan on going to be on Jasmine/SD lollipop builds you need the 23B modem and can't use any older ones.
So just remember to flash the 23B modem when you use Lollipop stock based ROMs for now, and flash the 12b(or later) for KK based (or AOSP) ROMs. I've forgotten a few times myself going from AOSP where I use the 12b modem and have seen the effects of having the wrong modem installed on SD LP. It constantly drops and switches around between 4g and 1x or just no service.
*All the modems are available in post #4 of the Jasmine thread :good:
Okay, that makes sense. Thank you so much for the explanation. I will try this tonight!

Hey guys, I'm not new to rooting or flashing ROM's but I've encountered some issues. Basically, I was on an early JB Rom and everything was working fine but it mostly was in roaming and would go from 2-4 signal bars.
I backed up and have attempted to flash:
PACman
MIUI 2.11.23
As well as CM10 by joker and AOKP CM 10.
Every flash I end up with no signal bars and no roaming, also following all install instructions in the threads.
I have tried flashing with and without prop tweak, i have even restored the backup all with the same results:
Empty signal bars, occasional R for roaming, every call says mobile network unavailable.
I have also fixed permissions, and have tried to flash via TH3Bill CWM and TWRP recovery... what am I doing wrong? The backup isin't even working!
I wouldn't know off hand, but here's something you can try while waiting for a more professional member to come to the rescue.
System Settings> More>Mobile Networks>System select>Home only
What's your current PRL, APNs?
if it was me I'd sbf back to stock and see if I had signal then go back and try a custom rom again

Before sbf'ing if you have a back up of your stock ROM or any ROM that has the update profile/prl setting in it, restore that back up and try updating your profile/prl then wipe/flash your new ROM.
I usually have this problem when I switch back to my Photon from my ET4G, but updating the profile usually does the trick.
When I restored my old backup, I had the same problem. The only fix I could find was on MIUI and selecting automatic netowrk before flashing options chooser. Any other rom would make no changes on automatic or home only. I am going to try a fresh install and if no luck will sbf today. I'll keep you guys posted.
Thanks!
**EDIT** Does it matter if I use Th3Bill's CWM recovery or TWRP? I have tried both with similar results. I jut noticed CWM is usually posted with the ROM builds... does it makes a difference? If so, what should I use?
Normally both work just fine, as long as you're using one of those two
I spent too much time flashing roms and wondering why they wouldn't work right, when I was using the stock CWM
I think It's just my opinion but I have preference for bill's cwm
Having this exact same problem. Did anyone figure it out?
No Radio/Signal
I recently flashed the latest MIUI.US V5 3.4.5 for the Photon provided by Th3Bill. I am familiar with the process of applying ROMs. I tried to go back to Beanstalk, JB, and ICS and could not recover the radio signal. I even restored a few backups with the same result, no signal. I flashed the MIUI V5 3.4.5 ROM back to the Photon and it worked flawlessly. Can anyone please help? I would really like to get off the MIUI ROM, it does not appeal to me like the standard versions of Jelly Bean that Th3Bill has produced.
I Odin'd the MJ9 radio some time ago and have been able to flash 4.3 custom ROMS based on that radio with no issues at all. The problem comes when I try ANY 4.4 ROM. The ROM and Gapps flash and install with no issue. However, I don't have data or voice connectivity. I'll go into APN settings and it's blank. I've tried manually entering the values, but the changes won't stick. As a point of reference, I'm running the MJ9 radio with TWRP 2.6.3.0 as my recovery.
Ideas?
Use philz or cwm for flashing the 4.4 roms

Where are you getting the 4.4 roms? Just make sure you are flashing ones for our device i605..
Only other suggestion I can make is making sure mobile network is toggled on..
You shouldn't loose data if you are flashing the proper rom
ROMs are all coming from this very forum. I never occurred to me to check the mobile network, because it's never been an issue with any of the other ROMs I've used.
Been a lurker for quite some time, there are some amazing devs on this forum and I can't find an answer to my question yet.
So I have a vs985 and it came with stock 12B on it. I used the kdz method to get back to 10B, then used stump root and flashed the bump'd TWRP 2.8.0.0 and immediately flashed TWRP 2.8.5.0. I tried using that to get back to 12B using these image files. In TWRP I flashed autoprime's "flash2" method to flash the system.img but it flashed nearly instantly, without actually doing anything. It says Finshed. Ok. but nothing was changed. You'd think I would just be able to flash a custom rom and move on right?
Correct.
But I can't use data on any custom rom. If I flash Jasmine, Cloudyfa, Skydragon they all work flawlessly... but data doesn't work. The only time data works is in 10B.
Any ideas?

Hi! Welcome to the forum from the writing perspective.
There's a separate autoprime flash2 for modem, isn't there? I know 11C modem works with 12B ROM, but I don't think anything older - based on what I've read others saying. I've only used 12B with 12B.
You also want the boot.img, IIRC. That's the stock kernel, or flash a stock-compatible kernel but I'd start with stock and make sure all problems are resolved first.
Thanks, I figured it out!
But I still can't use data on custom roms, which I know will bother me down the line. Any idea whats up with that? I successfully flashed the boot.img, system.img, and modem.img. Running stock on 12B everything works great! I know I'll eventually want to try out other roms, but I can't use data on them!
I have signal, the 4G LTE icon appears, but I'm always in "Offline Mode" when on data. Data is on and enabled. Not sure whats up. I would think its a radio problem, but I've tried the attached radio with Skydragon and the one on Jasmine ROM (which is the stock 12B). I went through and can't change my APN settings, I can only change the connection name. I have the network type set to Global, but I also tried leaving it on CDMA/LTE. Seems pretty odd to me. Especially since it works 100% on stock 12B.

Check your IMEI number. Is it zeroed out? If so, then go here to fix it -> http://forum.xda-developers.com/showpost.php?p=58915450&postcount=3
Ok, i'm fairly new to this stuff but have successfully rooted and modified several of my devices over the years. I've been attempting to upgrade my vs985 to as close to stock 5.1.1 as i can and after much reading decided on jasmine. I was rooted on kk 4.4.2 12b and I had no problems. the main reason i wanted to upgrade was for compatibility with my android play car stereo. I didn't have twrp so first i downloaded flashify and quickboot then flashed twrp from flashify. All good so far. Next I downloaded jasmine 9.0 and 9.1 or at least i thought lol. As it so happened i mistakenly ended up with one of the files being just the kernel for 5.1.1 35b. Must of been a long day cause I mistakenly failed to backup my current system and proceeded wipe data, cache, dalvik, and flashed the kernel file. As you might imagine it didn't turn out very good. I was stuck in boot loop. Fortunately I could still get into download mode so I was able to use the lg flash tool and I brought it all the way back to 10b stock firmware. Then i grabbed stump and rooted and flashed twrp again. at some point i noticed my cell signal was all over the place, up, down , no signal and it roamed almost constantly if there was any signal. I've had this phone and service for well over a year and never had anything like this at all. I knew it was something I did. I checked the back cover to be sure it was on properly and had good connection with the antenna and all checked out. I decided to go ahead and do the upgrade to jasmine 9.1 hoping this would correct the issue. Well no dice. I did create a backup this time and proceeded to wipe everything and flash 9.0 reboot then wipe nothing and flash 9.1, i guess as you call it "dirty" then reboot again. Here is a link to where i got the zips and instructions
http://forum.xda-developers.com/showpost.php?p=63305722&postcount=4842
in the instructions it says "RESET factory from within ROM (in Settings) - REQUIRED" . this step seemed strange as why would i do a factory reset on my device and erase everything i just did? would it not return it to original? I wasn't even sure if that was what he meant so i skipped that. After all was finished my signal was still all over the place could hardly make a call. it was bad. So once again I used lg flash tool and returned it to stock 4.4.2 10b, this time I wiped the data, cache, delvik and system. To my complete surprise the signal had not improved, in fact it could have actually been worse. As I said waaaaaay at the top of this post before i started all this i was running 4.4.2 12b, not sure how i ended up with 12b as i don't remember any upgrades after i downgraded to 10b and rooted. I froze the ota's with titanium backup but maybe 12b was pushed before i was able to freeze them. Anyway I couldn't figure out how to get 12b back now so I just flashed the 4.4.2 12b modem instead, This time I wiped cache and delvik before and after the flash then rebooted. This fixed my signal, everything seems normal now. no roaming and good signal. my software build however still shows 10b, but I guess thats correct since I only flashed the modem.
I really want 5.1.1 on my G3 but I need my signal too lol. can any one help me figure out how to get this done, can I flash the 12b modem on 5.1.1 this is where i got the file
http://forum.xda-developers.com/verizon-lg-g3/development/rom-jasminerom-v1-0-t2904641 it is way down the bottom of the page. Sorry for the extremely long post i just wanted to make sure i didn't leave any details out.
Any help would be greatly appreciated,
thanks in advance

i dont know if jasmine flashes the L modem when you flash it, but if it doesnt, that would be why you are having issues after flashing the rom.
other than that, i dont know what would cause modem issues.

TL;DR but yes, JasmineROM flashes the appropriate modem. v9.0 only flashes the 24B modem because it doesn't contain a fuller set of the necessary partitions to allow the 35B modem to work by simply replacing the 24B modem with the 35B one.
You can flash the 35B bootstack after flashing JasmineROM 9.0 and the 9.1 update, or SkyDragon 6.x, but you must not be on the 35B bootstack before flashing either UNLESS you also flash the 35B bootstack again after flashing the ROM.
For reasons why: http://forum.xda-developers.com/showthread.php?p=64064555
Edit: I meant to add, the 35B boostack contains the 35B modem and everything needed for it to work with JasmineROM 9.0/9.1.

In the future, please do not post the same thing in two different threads. This is against XDA's forum rules. Also, no reason to hijack an only partially related thread. I answered you in the JasmineROM thread.
Sorry for rule breaking, actually i did not aware of that. will avoid surely next time and thanks for reply. hats off to you.
Thanks for your help guys. Last night I figured out my phone was allowing me to send and receive text messages and make outgoing calls but was completely unable to receive any calls. Signal still terribly inconsistent, it would be on 4g one minute then you could watch as it dropped then no service. There'd be no service for 3 or 4 minutes then it would repeat that cycle again. If I switch from global to cdma/let in settings it would immediately regain full signal. Then the cycle of it dropping out would start again. I got to looking through about phone in settings and realized my imei number was missing, all zeros. I'm assuming that probably is the root of my problems. Not sure what to do, I doubt Verizon can help. Phones not insured or under warranty anymore. I haven't researched this New development on te forums yet it got to late last night. If anyone knows of this problem I could use your help. Thanks

If you go into the main Verizon G3 section or possibly the non-Verizon G3 section and use the search field to search for "IMEI" you'll probably find a helpful thread. I think it involves the QPST program on a Windows PC. You'll need the IMEI that it's supposed to have, so hopefully have that on the box or Verizon's website lists it.
Sometimes that's seemed to happen for some people when flashing TOTs, KDZs or ROMs. I've been lucky, it hasn't happened to me through all my flashing over the past year. Once you get it fixed, rooted and put TWRP on, you can back up the IMEI partition in TWRP. It's called something else in TWRP like EI or something - I forget.
Good luck!

I have spent sooooo many hours on this. The qpst apk wont see my phone I have done everything the tutorials suggest. the instructions are only applicable if there are no issues, in other words, in a perfect world. I'm sure its something stupid and very simple but I don't even have a place to start. First, its hard to believe this works on all OS's, but it doesn't state anywhere what it is and isn't compatible with. that info would be helpful. i have spent 4 hours a day for over a week trying to get this fixed and I'm no closer than i was when I started. Very frustrating. I'm still open to suggestions or any help that can be offered.

+1000 to this request
I wasn't able to install it so you got further then I did. But I had that same issue on a number of non-stock ROMs and never found a "fix" other then trying diff nightlies until one worked. Another is very flaky WiFi which I'm seeing on XenonHD
Just simply give up. Nobody really has ever gotten an international GSM rom with working LTE on the VS985. A couple of months ago we got 3G working on fulmics 5.0. However to my dismay, when I flashed another ROM, I only had 3G data no matter what I used. It turned out that it wiped my EFS partiton, the one that controls call and data information. I had to wipe my phone with the stock KDZ file, and then re root and unlock.That really, really sucked. Moral of the story: give up on the international roms that say they're 'compatible' with the VS985. They're not.

Fulmics was a wonderful ROM except for Verizon 4g, so now I'll restore to something else. Wish I knew this first, wasted a bunch of time.
No problem man!
I've got it working, I think, my data icon shows a 4G. I've found a post in fulmics thread that says to get it working you should wipe, flash then bootstack, flash fulmics and once again flash the bootstack.
Some times in former versions i've got it working just wiping, flashing fulmics, booting without data and flashing the bootstack after all, so I guess that flash the bootstack after fulmics gets the point.
Give it a try and post back!!!

I've tried that before, however all I ended up getting is a 4G roaming data icon. Is it showing as roaming for you?
I would go back to fulmics, but I'll admit I was only using it to have a little look at UX 5.0. Then it wiped my EFS partition, so I'm not gonna go back. If it works for you then great! Happy on xenonHD right now though.
