[Verizon LG G2] JackpotClavin:
For those wondering why I advise you to make a backup of your EFS partition, read here: http://xdaforums.com/showpost.php?p=55514429&postcount=2035

TLDR: The KitKat RIL (radio) files had this strange issue with AOSP where something would get written to the EFS partition, and we would lose 4G unless we restored an EFS partition backup. This was an issue when I first released the CM11 based on LG's 4.4 OTA way back last April. Since then I've been using the 12B RIL files from Jellybean as they didn't have this RIL issue. Fast forward nearly a year, I'm trying the Lollipop RIL files in this ROM, and hopefully whatever was messing up the EFS partitions on AOSP with the KitKat RIL files has been resolved.

If you suspect you have lost 4G, reboot your device and see if 4G gets restored. If it still hasn't been restored, reboot into recovery and restore your EFS partition. When you reboot your phone verify that 4G has been restored, and report it here. I'm hoping that the Lollipop RIL files will resolve everything (I've been running builds with the VS980 39A blobs for the past week and still haven't had this issue yet, but it might be due to good luck)

Anyways, the new RIL files will hopefully being VoLTE once this ROM gets upgraded to Android 5.1; whenever that day may be
[Verizon LG G2] jesssiii:
I didn't backup efs, have it on my computer. But I don't have data. Going to try a reboot, then go put the efs backup on my phone and restore if necessary.

Edit: Yes, had to restore efs [MENTION=3727492]JackpotClavin[/MENTION].

[Verizon LG G2] steveo17:
do we need just the 39A radio or the 39A bootstack too?

I am currently on the 26A bootstack and radio
[Verizon LG G2] jesssiii:
Flash the 39A bootstack.

VZW LG G2
[Verizon LG G2] steveo17:
thanks

i'm up and running. data is working fine.

proximity sensor on calls doesn't seem to be working though
[Verizon LG G2] JackpotClavin:
Are any of your sensors working? For just the prox not to work is strange.
[Verizon LG G2] mattskent:
No sensors here either. Data seems to be working fine without having to restore the EFS partition backup.
[Verizon LG G2] JackpotClavin:
Okay, I'm wondering if this may be due to the fact that I was on the actual 39A build beforehand. If you delete /sns/cal/sns.reg and reboot, do they work?
[Verizon LG G2] steveo17:
Doesn't look like i even have that directory

Also auto rotate doesn't work either
[Verizon LG G2] koftheworld:
Did you turn on root?
[Verizon LG G2] mattskent:
Nope, still nothing.

I couldn't find it with Root Explorer either. I just did a "rm /sns/cal/sns.reg" from a terminal window.
[Verizon LG G2] steveo17:
Same here. Ran the command. Reboot and same results
[Verizon LG G2] zman0125:
So to confirm, I can flash the 39a boot stack and then dirty flash the 3/14 build over the 3/4 build?
[Verizon LG G2] mattskent:
Yes, that's what I did. I ended up with sensors not working though - you may want to wait until that gets sorted out.
[Verizon LG G2] JackpotClavin:
I'm not sure what to make of this sensor business right now. I just deleted my sns.cal file and rebooted and mine ended up working again. You guys went from my old build right to this build, while flashing the modem in between right? You guys weren't ever on the 39A build at one point?

I'm just trying to replicate this issue
[Verizon LG G2] mattskent:
Yeah, that's right. Never been on 39A, I was previously on your 3/4 build. I flashed xdabebb's 39A bootstack, then dirty flashed the 3/14 build and PA gapps.
[Verizon LG G2] JackpotClavin:
Kk thanks. I'll try to reproduce. In the meantime I've removed the build from the post
[Verizon LG G2] ddzado:
I flashed 39a bootstack. The about phone shows an unknown baseband. Is this problem?
[Verizon LG G2] JackpotClavin:
Not a problem, the string just isn't getting set like the old one was
[Verizon LG G2] xz124:
LTE not working

I dirty flashed over the 3/4 build after flashing the 39A bootstack. 3G works, but LTE doesn't, even after restoring EFS. Any thoughts?
[Verizon LG G2] ddzado:
My only other issue is that some apps are just not work. Google maps, moves, and most likely v4a.
[Verizon LG G2] jesssiii:
I went to this from crdroid, but previously was stock 39A lollipop then xdabbeb's 39A firmware too. I got root manually from stock via that new root process and used bouchigo's guide to get twrp.

I had to restore efs flashing this version of your rom, and even after deleting that sns file you specified above, I have no rotation. I didn't notice right away because I don't often use auto rotate.

VZW LG G2
[Verizon LG G2] JRJ442:
I was on the last build of JC's. Flashed the 39a bootstack. Clean flashed the new 39a JC build. Rotation didn't work. I didn't try Maps though or proximity. So I downloaded MicroMods 39a debloated ROM. Flashed that. Made sure rotation and GPS worked. Went back into recovery and clean flashed JC's newest. Proximity, rotation and Maps works. LTE works. I'm gonna try Bluetooth and V4a in a little bit
[Verizon LG G2] jesssiii:
Thanks [MENTION=3520986]JRJ442[/MENTION], I have my backup of xdabbeb's 39A firmware, so I'll give that a try.

VZW LG G2
[Verizon LG G2] HueyT:
That's a well known trick to flash stock, get GPS and sensors working, then nandroid back the AOSP/CM12 build to fix sensors and GPS.

Did that work for you, Jess?

JC, bring back the CM12-39A build--I wanna try :D
[Verizon LG G2] steveo17:
good call. going to try this now

thanks!!

link to the build

http://xdaforums.com/verizon-g2/development/rom-vs980-39a-lollipop-t3048690

flashed the stock build. got a gps lock and tested sensors than restored back to JPC. all seems good now
[Verizon LG G2] jesssiii:
Yes, all I had to do was restore my nandroid of stock, make sure rotation worked, restored nandroid of this rom. Rotation works now.

Now what I want to see is if the battery tanks the way stock 39A did. Hope not.

VZW LG G2
[Verizon LG G2] HueyT:
Bring back the build JC !!!

Sensors can be restored once people flash stock 39A first, get GPS and sensors working, then dirty flash your CM12-39A. This has been confirmed by 3 independent sources.

Please bring back your rom. I and others wanna try. :D
[Verizon LG G2] JackpotClavin:
Pulling build for now
[Verizon LG G2] HueyT:
Thank you, boss man :highfive:

---------- Post added at 04:26 PM ---------- Previous post was at 03:40 PM ----------

1) Coming from AOD-Dark (AOSP LP based on 12B), I flashed 39A bootstack by XDABBEB and reboot back to TWRP Blastagator BUMPED 2.8.5.1 recovery.

2) Restored my prior nandroid of MicroMod's 39A stock LP rom

3) Rebooted into stock 39A rom and got GPS lock and all rotation/light sensors working

4) Go back to TWRP and clean wiped (system, data, dalvik, cache) and flashed CM12-39A, PA Pico Gapps, rebooted back to TWRP

5) Restored data from CM12-26A and rebooted

All good here :good:
[Verizon LG G2] JRJ442:
My Bluetooth headphones pair fine. V4a works well too on the new 39a build.
[Verizon LG G2] Dick Ripple:
LG ties all of the sensors to the baseband so anytime you update to a new version you MUST flash a stock based ROM to get them calibrated. I'm pretty sure the sensor files were the same on all the different versions of the kitkat baseband. That's why no one had issues upgrading.
[Verizon LG G2] joedajoester:
[MENTION=3727492]JackpotClavin[/MENTION] , flashed the new build, and thank god you recommended to backup the EFS. Everything was working fine and, so then I tried a friends T-Mobile sim for the day and my phone kept hanging on boot after a few seconds so i had to airplane on boot and then turn it off after a minute. Afterwards i had no issues reaching >5Mb/s with T-Mobiles network. LTE was working fine and all, and then when i decide to return to Verizon before i get too attached to T-Mobile, LTE wouldn't work so i had to restore my EFS and then all was good. This doesn't make any sense how a tmo sim broke LTE for Verizon. I tried switching network back to LTE/CDMA and nothing. Only the EFS restore fixed it. What would I have done if i didn't have an EFS to restore from?
[Verizon LG G2] JackpotClavin:
The stock ROM can magically restore the EFS partition to working order. Not sure why but restoring to stock fixes pretty much everything that an AOSP ROM might break
[Verizon LG G2] xI mEzMeRiZe Ix:
Is there any fix for a GPS that won't lock? My GPS used to be shaky regardless of which ROM I ran, and now it just doesn't ever lock. I'm still running the 3-4 CM12 build, and I got a lock the first day I flashed to CM12, but now I can't get a lock whatsoever. I know this is a problem with this phone and I've tried reflashing to stock and trying to get a GPS lock, but even that doesn't lock.

Edit: I also just tried taking the back cover off and putting a piece of electrical tape underneath the gold tab, as many people have tried.
[Verizon LG G2] JDROIDS:
Are you going into "location" under settings and setting "Mode" to "high accuracy"? This is a must for getting GPS lock.

I am not sure but I sometimes think that half the questions about GPS locks are due to this because regardless of the ROM I never have an issue with GPS lock.

As far as the 39A version of this ROM, [MENTION=3727492]JackpotClavin[/MENTION] things are running really well. I have tried everything but the bluetooth in my car. Awesome Job!
[Verizon LG G2] xI mEzMeRiZe Ix:
...yes. The GPS is on and I even use an app to show me how many satellites are in view that I can't lock with.
[Verizon LG G2] HueyT:
Nandroid current rom, flash stock rom like 39A, get GPS lock, wipe clean, restore current rom, GPS should be fixed.
[Verizon LG G2] xI mEzMeRiZe Ix:
As I mentioned in my first post, flashing to stock doesn't lock either and I already got a GPS lock on CM12, but now I get no locks on anything.
[Verizon LG G2] Lawlrus:
If you can't get a lock on stock it sounds like hardware failure.
[Verizon LG G2] xI mEzMeRiZe Ix:
That's what I'm thinking, especially after the tape trick didn't work. Can't wait to ditch Verizon and their bastardized phones...
[Verizon LG G2] koftheworld:
To be honest, I dread flashing anything on this phone. I do it anyway, but it's hit or miss if I have to fight it for hours trying to get GPS to work. My process usually involves a revert to stock, installing a few different GPS apps, and then crossing my fingers. I love a lot of things about this phone, but GPS is not one of them. Maybe lg should partner with moto on radio and GPS and then let moto copy their camera tech lol.

I just got done fighting with this thing moving to the latest jpc build. Supposedly GPS is working but I'll find out for sure tomorrow.
[Verizon LG G2] joedajoester:
That does sound like hardware failure, sorry to hear. And I totally agree, today I popped a friends T-Mobile SIM into my phone and it was glorious. LTE all around towns and all towns around. Speeds were also decent, never slower than 8mbps, and even at times got up to 40. I am now certain that I'm going to drop evil Verizon and go T-Mobile.
[Verizon LG G2] xz124:
Is tap and pay no longer supported by the new 39A blobs? I don't see the screen in settings...
[Verizon LG G2] steveo17:
Turn on nfc
[Verizon LG G2] koftheworld:
I don't see it either and Google wallet doesn't show the option either. NFC is enabled.
[Verizon LG G2] steveo17:
Hmm. Seems like you're right. I'm not seeing it either
[Verizon LG G2] 4rsenal:
So to clear things up, when the build is back up and I want to use the most up-to-date modems and bootstacks, I can flash the 39a radio but not the bootstack? Or can I now flash both?
[Verizon LG G2] steveo17:
So 4g is suddenly not working and I deleted my efs back up. Suggestions?
[Verizon LG G2] koftheworld:
Flash back to a stock rom. Jpc said it fixes it.

---------- Post added at 10:43 AM ---------- Previous post was at 10:41 AM ----------

The build is back up already. Flash the entire 39a bootstack from x's thread, then flash stock 39a for sensors, rotation, and GPS, and then flash the rom after wiping.
[Verizon LG G2] jesssiii:
JPC said flashing stock then back would fix that (as well as a host of other things).

The build was put back up, if it's not in the OP, it's in the thread not far back. And you must flash the 39A bootstack only (that contains the radio). Then rom and gapps.

VZW LG G2
[Verizon LG G2] HueyT:
Wonder how 5.1 will play with 39A bootstack? It'll probably drop in 1-2 weeks for G2 :good:
[Verizon LG G2] koftheworld:
Lots of assumptions there. Tph, I am most excited for HD calling. I didn't think I would hear a huge difference, but I actually miss it.
[Verizon LG G2] steveo17:
So I flashed a stock build and I still can't seem to get 4G 3G only no matter what I do
[Verizon LG G2] HueyT:
Change LTE to Global or vice versa, and if all else fails, restore EFS
[Verizon LG G2] jesssiii:
He said he deleted his efs backup. Thank God I kept a copy of mine on my computer! From what I've heard, a bad efs is one of the few ways to truly get a brick.

VZW LG G2
[Verizon LG G2] Lawlrus:
Try a new sim
[Verizon LG G2] steveo17:
Can I restore someone else's efs?
[Verizon LG G2] HueyT:
Sometimes efs is backed up automatically with nandroid. Check all your saved nandroids. I don't think somebody else's efs will work due to IMEI incompatibility. New sim should be free and should work also.

EDIT: try this APK and choose "phone information" and see what it says

[Verizon LG G2] Dick Ripple:
If anyone gets tap to pay working please post instructions. I use it daily.
[Verizon LG G2] HueyT:
1) remove that photo ASAP as it has your imei number

2) try to change your cellular settings by scrolling down to "Set Preferred Network Type" to "LTE/GSM/CDMA auto (PRL)" and if that does not work click on the top right "3-dot" menu and click "Select Radio Band" and choose "USA Band" and then retry to choose "LTE" again.
[Verizon LG G2] steveo17:
Thanks. Didn't work either. Going to the store now to get a SIM
[Verizon LG G2] koftheworld:
I think it's a problem with cm itself. You'll either have to restore a nandroid or wait for the next build.
[Verizon LG G2] steveo17:
So new SIM didn't go the trick either. I'm going to revert to 100% stock (kdz) and see if it works
[Verizon LG G2] HueyT:
Sorry dude, here's 27A KDZ http://csmgdl.lgmobile.com/dn/downloader.dev?fileKey=FW8BCUME0231ASHA4A40RQX/VS98027A_05.kdz

Thanks for the help!

I actually restored to the stock backup that I had (4.4) and then flashed the 12B bootstack and that got me 4G do then I flashed 39A and this build and it's working all good again!
[Verizon LG G2] ddzado:
So how we get a sensor file without flashing stock? Will the next build just fix this?
[Verizon LG G2] da_reeseboy:
You don't get it without flashing stock... At least not at this point in time. On the major baseband changes (jb > kk, kk > lp), you really need to go stock first and get all the sensors working and then flash the rom you wanted.
[Verizon LG G2] ddzado:
Okay. Not excited about that. Would a backup work?
[Verizon LG G2] jesssiii:
Yes.

VZW LG G2
[Verizon LG G2] JackpotClavin:
I think I'm gonna put it in the instructions that users should boot once into the stock ROM and make sure their GPS and LTE work on the stock ROM.

It will standardize everybody's experience and ensure that no issues with sensors and LTE occur. I did this with the builds based on KitKat and I suppose it's the best thing to do for Lollipop.

I apologize to those who have had headaches with sensors and LTE not working. I didn't know it was an issue as I went from booting into stock 39A to the CM12 builds based on 39A and it didn't occur to me that going from the KitKat modem straight to the Lollipop modem would create issues
[Verizon LG G2] KBizzle:
I'm a bit confused. Can we run the newest beta with the 39a bootstack or do we have to stay on 12b but flash the 39a modem?
[Verizon LG G2] soapinmouth:
You plan on putting the build back up then or are you keeping it down to do more work?
[Verizon LG G2] rockcipher:
On 3/14 I'm having an odd issue with GPS... I got a lock on stock, but now apps like GPS Status and Phone Tester don't show a lock at all (0/22 satellites)... But do show my location with an accuracy down to 4 meters. This is all with my location set to device only. All other sensors are working as expected.
[Verizon LG G2] koftheworld:
This is exactly my situation. I used GPS this morning with no issue, but I see the same thing.

---------- Post added at 08:09 PM ---------- Previous post was at 08:08 PM ----------

[MENTION=3727492]JackpotClavin[/MENTION] Do you have tap and pay working on your end? It isn't then in settings that I can find.
[Verizon LG G2] JackpotClavin:
I haven't used GPS but I did get a lock when I tested the build, so I assumed it worked, but it might not be working according to recent posts

As for tap to pay, I don't use it ever so I'm not the one to ask :/
[Verizon LG G2] soapinmouth:
I was able to upgrade without loosing sensors or gps without having to actually boot up the up and set up the stock rom, just installed it then installed this right after.
[Verizon LG G2] koftheworld:
I still get location and navigation works it's just that it shows no sat locks. It's strange but seems to be a cosmetic issue.

[MENTION=3727492]JackpotClavin[/MENTION] I know that you don't use it (I've seen you mention it before :0) ). I just wanted to know if you even had the setting anymore.

FYI I had two random restarts while using chrome beta just browsing a few pages. I didn't get a log (of course), but just thought you should know.

[Verizon LG G2] natemup:
What does it mean that we need a KitKat/Jellybean aboot image?
[Verizon LG G2] HueyT:
39A bootstack made by XDABBEB (in the stickied resource thread) already has 28A (KitKat) aboot/bootloader which allow it to work with BUMPed (39A aboot is not compatible with latest TWRP or BUMPed) stuff, while still keeping 39A modem/baseband
