vs980 LTE fix? - G2 Q&A, Help & Troubleshooting

previous to this day everything had been running smoothly, but now since i flashed the 39a bootstack to try out a new 5.1 rom on my vs980 i seem to have lost my LTE connection. how would i correctly repair this? i head flashing a stock rom would repair some sensors, would i leave the 12b bootstack on it, flash a stock build, then flash back to say, beanstalk? previously running liquidsmooth but they seem to have taken their lollipop builds off the server...

I have the same problem - flashed Cloudy ROM, kdz back to stock but now I don't have 4G. I'm about to just try a new SIM card and see if it went bad, because I saw LTE for one day a few weeks ago and this all happened back in January. I've reset APN's and did all of the tricks but no luck so far

Literally just got it to work a few minutes ago. As of this morning had NO service whatsoever, ended up flashing the rooted 39a lollipop stock I found here in the forums. I had to remove my sim card, boot the phone, then restart it with the sim card in place to get back to working order

So do you think it was a bad baseband or bootstack? Or just a faulty download from the start?

might be a baseband issue, but then again i havent really gotten a solid answer from anyone.
and just flashed to AoD rom tonight and lost LTE again. maybe it has something to do with aosp incompatibility? i know there have always been issues with cdma network of verizon, maybe it came back fresh with the lollipop update.
and i despise the stock roms... i would not be happy if thats the only way to fix this.

If you haven't try dialling *#*#4636#*#* and go to phone information and in the drop down menu select the proper mode for your carrier. Worked for me on VS980 using T-Mobile

[Q] No Data Service on New Resurrect or Blisspop ROMs

Edit: Fixed using this - http://forum.xda-developers.com/showpost.php?p=53502055&postcount=16
Newer ROMs don't seem to have the correct settings for the Ting APN. Make sure the network type is strictly CDMA/LTE and in particular that the APN Type is set as both DEFAULT and as mms (default, mms).
Hey guys, hoping someone can help me out here.
I'm on the "Ting" cell network using an LS980. Resurrect Remix ROMs worked well for me up until the 5.3.8 update (5.3.7 was the last version that still gave me cell data). The new 5.3.9 also causes issues and the SIM card even completely locks itself at times as it attempts to contact the network.
I just installed the latest Blisspop nightly ROM and am having the same issue. I know that older LiquidSmooth ROMs were also working properly for me aafter I used one of them as a Plan-B from Resurrect.
If anyone has any ideas as to what the issue could be please let me know. I'm going to try tinkering with my radio files soon and see if I get anywhere.
Bumping. sorry but this is getting really frustrating. I tried flashing the ZVC and ZV8 modems and it didn't make a difference.
ZVC modem actually crashed my phone (running Blisspop 2.2 latest nightly, stock kernel, TWRP 2.7.x recovery) after attempting to flash the ZVC modem without clearing the cache/dalvik afterwards.
I've now restored my phone to factory, stock ZVE ROM and rooted using StumpRoot. I'll be putting on the TWRP recovery soon.
If anyone has any ideas as to why I'm having radio/modem/signal problems on any Resurrect ROM past 5.3.7 and with the new Blisspop please let me know. I really want to get back on a non-bloated, up to date ROM.
>tfw
Bumping again. My phone is actually having a few other odd issues now after having to go back to stock with the ZVE .tot and re-rooting/recovery...
I'm still mostly concerned with the data signal though. I'll sort the rest out myself.
PLS SUM1
Ayyyyy Lmao

[Q] Updated phone and lost my LTE connection..

Ok here is what is been happening so far..
I was on Kitkat 4.4.4 on a i9505 (can't remember the baseband info for that model - never had issues with it). I decided to update. So I downloaded a LP ROM and went ahead and backed up and then installed it. Everything seemed to be working fine except my mobile data connection. It would be stuck on 3G or H+ and when it hit the LTE (4G) it would have one bar. I never had this issue before. I was always on full LTE bars as the tower isn't far from my house.
I followed instructions n how to install new modem with LTE and how to update the bootloader accordingly. I tried more than 15 different modems with no luck.
When that failed, I flashed the stock LP ROM from SamMobile - same issue. So I decided to downgrade again to KitKat and flashed another ROM from SamMobile which is issued by Optus Australia and that failed too.
It's like there is a setting that isn't changing with flashing ROMs and stock ROMS. Basebands get updated and nothing.. I'm barely downloading at 600kbs where I was averaging minimum 1.5mb/s.
I don't know what else I've missed.. surely the stock KK ROM would've fixed the issue.. but nothing, as if I don't have LTE anymore.
You're help is much appreciated.
Over this issue =\ just want it gone.

[BRICK] Lost and Unable to Restore IMEI/BASEBAND LG G2 D805. (EDITED: D802)

I'm really going to die soon. I spent the whole day trying to restore my IMEI as I don't have the original box (bought it second hand just the phone alone) and did not have EFS back up prior to flashing.
So, the whole mess was when I flashed Dorimanx for D800 instead of my variant which is D805 (my careless mistake, the title of the page was really confusing). Ever since, I lost my IMEI is shown as 0 or null so does my baseband. I then flashed ResurrectionRemix, PowerG2, etc. but still unable to get any mobile network connection.
I've tried reverting to stock KitKat firmware but to no avail. I've flash other modems as well with no success. I've even tried the QST NvManager switching from Windows 10 to 7 and re-installing the USB drivers numerous times still no luck. I followed so many forums and watched endless youtube tutorials none of them can fix my problem.
I'm really desprate, please help me.
how can the tile be confusing.? even qhen you go to download page theres all the variants. was kernel really the culprit of this.? am not really sure that kernel would damage imei and baseband i think flashing bootloaders do. twrp wrong rom. ect. you should post this in the q&a thread. i know some have restored imei.

Dear @raptorddd
Thank you for your feedback and I'm sorry. I did not blame the kernel as in whole context but rather my careless mistake and take note I suspected my problem was flashing the kernel for the wrong model variant so it was not actually Dorimanx's issue, no offense I even admitted my wrong-doing.
Anyway, after reading your reply at least there is a light to my answer. I will do some more research on bootloaders for my exact variant because most of the threads found here are for D802 International while mine is Brazil (Latin America) although I'm from SEA.
I was very happy when I see 6.0 MM on this frakenstein device but now I have this network problem making me sad. It's like having an old car with a new engine but no wheels. Please help.

I don't know how a kernel can wipe your imei. Have you changed roms succesfully before? Have you used ioroot on it? Ioroot makes efs backups automatically. That would help.

@raptorddd @Art Vanderay
I figured out. My phone is actually the D802 variant. It is obviously shown at the back of the case and when I open the back case, the model number is also printed just underneath the battery D802. I thought it was D805 because when I bought this phone it was already rooted and running PowerG2 and the model shown at the About page was D805. This is why I started looking for stock firmware for D805, TWRP D805, Dorimanx D805, and everything D805. So, when I downloaded ResurrectionRemix 6.0 MM, that was when my phone started to act weird but I'm very sure it was not RR issue as well. I wipe all my partitions without making any backup just before I started flashing things. I've done this 1000 times with no problem and this is the only time I got it wrong. I've tried flashing the bootlader changer aroma, then KitKat bootloader stock and still no IMEI, the phone number shown as unkown. I now got back my baseband because I flashed the KitKat baseband.
I'm going to start all over again today, and I'm getting all the files for D802 instead and will let you guys know if I can restore my IMEI back. Thank you for your participation on my thread, very much appreciated.

I'm sorry, I have a soft-bricked phone right now with no spare phones, so I don't have WhatsApp at the moment but thank you really for your effort and offer. Can you explain on the forum instead of TeamViewing so others that have this problem and reading this thread can solve theirs? +1 for you.
YES YES YES!!!!!!!!!!!!!!!!!!!!! I FOUND THE ANSWER ALREADY. Please ignore the caps, this is just to show you how happy I am.
I've spent approximately 48 hours to figure what the heck is going on.
What I did was:
1. Flash stock firmware Brazil KitKat D805 .kdz through LG FlashTool 2014.
2. Use ioroot25 to root it via adb.
3. After rooting, download AutoRec.apk for KitKat and install that.
4. Download TWRP bumped latest and flash it to replace AutoRec's old version of TWRP.
5. Flash Dorimanx KitKat 10.9 (at the time of this post) or latest.
6. Flash KitKat stock baseband and modem for 20d.
After rebooting system, everything is ok. I got back my mobile network now. So happy!!! I'm requesting the moderator to close this thread as my question as been solved.

I'm not sure also. The back case written as D802 and just below the battery also written as D802. But when I tried to go back to stock I was unable to use D802 firmware but only can use D805 stock firmware. I'm now on Google Edition 1.3 the model is written as D802. When I try to flash stock D805 firmware I can't get through already. Im not sure why but as long as I can use the phone right now, I don't want to bother so much about that.

So far, Google Edition 1.3 is the best/stable among all other ROMS that I've tried like Power G2, RR, etc. Nice battery life, 100% in the morning and came back from work still have another 30%-40% (usage mainly for WhatsApp, Facebook, internet browsing occasionally, no movie/music/games-just COC once or twice). This is the most straight-forward ROM and the closest to Stock Lollipop from Google without any other 3rd party apps and bloatwares. Very stable, no FC, great camera, and knock code gestures (flashed additional QuickMemo+ which isn't included by default). Awesome!

A300FU Signal

Hello! I have problem with my phone. I was on Cyanogenmod, but then i wanted to flash that resurection rom or whatever its called. Booted it up, but there was very weak or no network. Then I decided to reflash stock rom. On the first time there was no signal too, but reflashed again and everything was ok. I remembered that Touchwiz is unusable and flashed again CM. On the first moment, signal was ok, but after while it started to lag. Yesterday flashed back the stock rom, and for that moment everything was ok. Waked up this morning, and what do i see?? Yes, there it`s again. Weeak or no signal. Emergency calls only.
I checked that my IMEI is not changed. Have reflashed modem with odin, sometimes thinked that it was working, but reception keeps bad. Is anyone having same issue? Maybe you can tell me how to fix this and help me?
Actual signal in my house and everywhere is good, but all problems started when I wiped all data and flashed resurection rom or whatever.
Did you check proper support for the rom? Some roms in development(like one of the versions of the CM for the a300fu don't have properly working wifi

Unable to access 4G after flashing stock Nougat

I'm hoping someone will have had the same issue I'm facing and have a solution.
A few weeks ago, I decided to go back to stock Nougat from a custom ROM. Everything went smoothly, but I cannot access 4G anymore. 3G works perfectly fine.
Solutions I have tried:
Factory reset
Reset carrier settings (* # * #72786# * # *)
Update PRL
Update device config
Contacted Sprint Support and had them reprovision
Restored backup of previous ROM
Flashed custom ROM
Reflashed modem
Replaced SIM card
Does anyone have any other suggestions?
Model: XT1687
Carrier: Sprint
Bootloader Unlocked
Kernel: 3.18.31-Extended-Kernel
Build: Sandy-Stock-Debloat-V2

Thank you. I have looked at that thread many times but didn't try it because Sprint doesn't have VoLTE. My dumb self didn't even think that it might fix my normal LTE issue as well. Cheers
Welcome to the g5 plus, the most screwed up out of all Moto. Personally I feel 64bit was the start of all the issues, could be wrong, just my penny's worth. But then again, before that, we had not a single custom ROM with stable camera, we still don't. Maybe Moto borked this one.
