[Q] catching up on VZW G2 and radio/modem questions

Hey guys,
Just picked up my LG G2 and I'm trying to get caught up on everything going on with development. I got it rooted and flashed TWRP 2.7 and LiquidSmooth, but I don't really understand the radios/modem flashing. I'm currently on 11a. I flashed 12b a couple days ago but started having major issues with just hangouts not receiving messages while the phone was sleeping which was a little weird. I flashed it back to 11a and works fine now. Any ideas what would cause this? Any major issues with any of the radios? Can we just flash them, test them out, then flash back?
Thanks!

I'm fairly certain you can test it out as long as you backed up the efs beforehand http://forum.xda-developers.com/showthread.php?t=2451390 but I'm also experiencing weird problems with the radio I think its that my rom uses T-mobile LTE and Verizon for everything else. :/

Radios only seem to control WiFi, data, and rotation.
When I was on 11a I flash the 12b radio and didn't notice any gain, or issues from it. If you're not having an issue with LTE or WiFi hand offs or anything, then there is really no reason to mess with flashing radios.
Its possible that's why you're having issues with your MMS. They send via data. I'm on liquid and haven't noticed the problem myself, but with some Roms I've had to turn off WiFi to get MMS to work. Not sure if you're on WiFi or not.
Not sure if you did it, but if you choose to flash radios, make a backup of your efs. In the radio thread he links his other thread where he has a flashible zip that backs up your efs so you can email it to yourself or put it on a PC.
Radios can screw up your efs, and if it does you're screwed. If contains your imei number it each phone had their own. There's no way to get it back.
Also you might know but other people might not
Modem, radio, and baseband, are all the same thing. People just call them what they choose.

[Q] 24A Baseband Flash - No 4G

Everyone - In preparing to flash tp xdabbeb's ROM, I wound up inadvertently wiping not only the cache but the system files on my vzw LG G2 as well. The only thing left was twrp 2.7.
Thanks to ADB I was able to sideload xdabbeb's ROM as well as the vs980_1xx_to_24a_twrp ROM. Everything is back now, however the phone is only using 3G for signal and not 4G. Could this be related to flashing the 24a ROM on a clean phone (no 11a or 12b existed). Or, is this an anomaly that should take care of itself?
Any help most appreciated.
Thanks.

Wild guess is you're still on old radios, what's your baseband version in Settings, About Phone?

I had this problem flashing 24a flex Rom. I restarted phone after installing the baseband and all was well

switching roms
somewhat of a noob here...I am on verizon 26a modem, running xdabebb's G3 rom that was ported to the G2. Can i just flash this over top? Or do I need to work about Kernel issues? Also, does knock on/off work?

You'll need to flash the modem I have posted. And yes, knock-on/knock-off work! Enjoy!

Attempted to flash
Flashed 12b radio, but then got this error after I started to flash ROM. It started then after it flashed supersu I got the following:
unmount of /system failed; no such volume
assert failed: run_program("/system/bin/loki.sh") == 0
Can you help?

What recovery are you using? Also, did you do a clean install and in the order I posted?

beanstalk L is amazing...BUT!
I love the setup of this ROM..plenty of options plenty of customizations HOWEVER I've had two issues that are rather aggravating.. While using Pandora it will intermittently stop playing music to the point of having to reset the app...(might try uninstall and reinstall?) Also I'm having an issue that started while using Pandora and now happens every 15 mins it would seem (have not timed it) but its rather regular that my phone will reset randomly..tried wiping cache and dalvik and fixing permissions and it still does it! Any ideas??

did you do a clean install?

Doing well
yes i did, infact i flashed over to another 5.0 version just like the beanstalk build and it was nice but i wasnt satisfied with the overall layout like i was with beanstalk so i flashed back to beanstalk and ever since ive had 0 issues, its turned into my daily driver and i enjoy it throughly, thanks for posting this one up m8!

Quick question here. Does this have the ability to bypass VZW for the tethering/hotspot?

Great work
the best lollipop rom with no bugs and lot of options with great battery life for my vs980

I have a rooted lg g2 verizon with 24a, Can I flash this rom downloading to 12b without any problem ??

@mrlugo88
- If I understand what you are asking, yes. Tethering/Hotspot is enabled without the need to pay for the service from VZW!
@ycruzb
- You shouldn't have a problem. I've gone from 24A to 12B to 27A, etc without any issues.

No Cellular or Wifi
I ran into such a headache installing due to my own blunder, but now I have it working. I have to add, I LOVE the boot animation. Had to get past the Setup Wizard and reflash the 12B Radio to get signal on WiFi, but I cannot get data signal over LTE?
Baseband: 12B-M8974A-AAAANAZM-1.0.190050
Network: NAM1
Mobile Network Type: CDMA -eHRPD [this is odd, as I have STRONG LTE signal]
Roaming: Roaming [I'm aware this is known?]
Edit: Flashed back to stock 11A. No signal. took OTA to 12B, gained 4G LTE signal. Then future OTA's granted me signal as well.
Any idea what I might have done?

rom issues
Hi guys, I have a Verizon LG G2 (vs980) with a 24a radio. The rom not works for me, the flashing process gives me an error then I have flashed the 12b radio via twrp (2.8.4.0 version) and now my device is not booting on my stock rom (the verizon logo is showing up but anything else is going on ...). I know that I can flash the 24a radio to restore my previous radio but I didn't copied the zip of the 24a radio to the phone, so my question is how to copy the zip of the 24a radio to the phone via adb for flash it with the twrp ??
I hope you can help me, please !!!

I had to flash back to 11A via a .tot file, then upgrade all the way to 27A via OTA. I then did stump brute-force for root, flashed TWRP Recovery, then flashed to this ROM. It is working incredibly.

Hi! You should be able to use adb in TWRP. Which version TWRP are you running? You can also enable MTP in TWRP and then copy right from your PC. Also, did you did a clean install?

Thanks!

SIM card not recognized
Hi everyone, I have flashed this rom (5.0025) and it's amazing but doesn't recognize the sim card. I have a Verizon LG G2 (vs980 with 24a, downloaded to 12b with the flashing process) mobile on GSM. Some help please !!!!! I love lollipop and this rom.

I'm coming from a 27a build, I wanted to try lollipop, so I tried to flash this but i received an error
E:error executing updater binary in zip. '/sdcard/download/beanstalk-
I received error flashing both builds.
I'm on twrp v2.8.1.1

Thanks for any help

I can't seem to get init.d working. Can anyone confirm that this is working for them, and if so, did it work on a clean flash, or did you need to workaround?

No Signal Issue on Custom ROMs

I have an unlocked bootloader and rooted Nexus 6. I usually run custom ROMs but I have had some issues when I install them for about the past week or so. I use Straight Talk CDMA which uses the Verizon towers. If I flash an official firmware such as LMY47I (5.1) or LMY47Z (5.1.1) then I have no issues with LTE connecting from the very beginning of the setup screen. Everything works fine including voice, data, and texting. When I install a custom ROM the signal will not connect and there is an exclamation point (!) next to the signal icon. I did have to exchange my phone and Motorola sent me a new one but I was able to use custom ROMs without issues on this phone until sometime earlier this week.
I know that people have been having some issues recently with connection problems and there are various threads on them. I have tried several of these workarounds but it just seems odd that I never had these issues before.
Any help or suggestions would be great. Don't mind running stock firmware but would prefer to be able to use custom ROMs again.
Thanks in advance.

Try a different radio. I've read that the radio from the M test build is fixing some issues.

I've tried flashing a few of the newest radios but not the Android M version. Will give it a try.
Thanks for the reply.

You can even flash an older radio if need be.

So I tried installing two different custom ROMs and both times I got the same signal icon with an (!) next to it. There is no working connection. I tried flashing the radio from the Android M preview and also installed the radio from LMY47D (Verizon 5.1.0) since I am on Straight Talk CDMA. Neither one seemed to help. After flashing these radios I went back to restoring a TWRP backup based on just a stock firmware. From what I understand the radio is separate from any particular ROM you flash and thus independent of each other. I am able to get an LTE signal when I revert back to the backup.
So now I'm stumped. It doesn't seem to be based on the radio. None of the custom ROMs that I was able to use less than a week ago are able to find an LTE signal after a clean install. I can only seem to use official firmware versions.
Any other possible ideas? Could the phone be defective? It was an RMA replacement and I think it was new and not refurbished.
Thanks in advance.

Really sounds like an APN issue. I have flashed a few ROMs and have had that problem. Most recently Exodus ROM. I changed the APN and all is well.

Let me take a look at the APN settings on the stock firmware and then see how they compare when I use a custom ROM. In the past, I never had to set the APN settings as I thought they were set automatically on CDMA sim cards. I'll take a look.
Thanks.

Even if there's another APN with the same name as the one set by default, try switching to the other. That's what worked for me on Exodus.

Droid Turbo cannot detect SIM Cards on ROMs other than Stock

While I was running CyanogenMod, I suddenly had a devastating issue where the phone would not even detect SIM Cards, and Bluetooth would sometimes cause the phone to force reboot. Afterwards some custom ROMs have the same issues, and reboot literally randomly, sometimes endlessly bootlooping.
The stock 5.1 ROM also had the issues but also didn't wanna connect to WiFi.
I recently followed a guide to install the 6.0.1 update on the Turbo, and suddenly, everything worked again. No random reboots, Bluetooth working, and WiFi. However ANY other ROM would have the issues.
Is there something that the OTA 6.0.1 update fixes that all other ROMs cause these problems?

No one else has those problems on custom ROMs. So, there's nothing to "fix".
No one would be running any of the custom ROMs if they had such issues.
Stock 5.1 also didn't have connection issues nor Wi-Fi issues.
Flashing 6.0.1 stock reflashed your radio, which "fixed" your issue, probably. THAT was probably all you needed to do. You can also flash @bhb27 clear modem file, which fixes stuff like GPS. Sometimes flashing a custom ROM will confuse a radio/modem and clearing the cache/stats with that file helps as well as reflashing the radio.

I thought that might have been what happened, but even after flashing the 6.0.1, which has everything working, installing a custom ROM gives the issues. Before this I always thought my hardware simply failed but this is the only ROM where it works now, the 6.0.1.
So what I should try is clearing the modem status or reflashing the radio even after installing a custom ROM just to refresh the things?

Yes, some of your symptoms like the endless bootlooping seem very unusual. I don't know of radio-related issues that cause that. But not being able to use GPS, Wi-Fi connection issues, or even not detecting SIM cards are symptoms of radio/modem problems.
When flashing a custom ROM on our Quarks, GPS especially was a complaint. There were workarounds to fix it as early as 2015, but then @bhb27 (who is the dev for several custom ROMs) came up with the @bhb27 Clear Modem File. You flash that. In simplistic terms it clears the cache of your modem. It has helped countless people, with Droid Turbo/Moto Turbo/Moto Maxx.
Often just that fixes any issues, but you can also then take the next step of re-flashing the most current radio/modem for the Droid Turbo.
ROMs don't have radio/modems included inside the ROM. When you flash a custom ROM, it uses the radio you already have. Clearing the cache, and reflashing makes everything new again.
We've had custom ROMs for over two years now for our Quark phones. True the Droid Turbo XT1254 bootloader was finally unlocked back in November of 2015, but still that's been 1.5 years. There's tons of custom ROMs and if you look at the download stats of those ROMs there's THOUSANDS of people using them. If the ROMs had the issues you had, there would be no users, believe me!
The issue is for a percentage of people, not even a majority, but a percentage, the radio/modem becomes confused when flashing a custom ROM. But it's easily fixed...
Go look at this page from just two days ago. Similar issue with AOKP 7.X. EXCEPT it's NOT an issue with the ROM. It's the issue of someone not reading thoroughly.

Unfortunately, flashing the clean modem.zip didn't bring about anything than a very temporal fix. Now it's basically a complete crapshoot as to whether I will get complete silence on my end and my mic muted for the other person, or whether the call will go through, but after some a mount of time I will lose all audio and my mic will mute. A couple times calling worked fine. Would you recommend flashing the XT1254 radio/modem zip you included now that I've flashed the clean modem?

Yes, if you have an XT1254.
In TWRP, flash back-to-back with the Clean Modem file first, then the radio/modem.
Then let TWRP clear all caches (it's an option anytime you "install" something), then reboot to system.

FYI: just re-flashing the modem doesn't fix all issues -- and just flashing the Clear Modem file doesn't always fix all issues (but it does fix a lot). However, a combination of the two, YES.
Back before the @bhb27 coded the Clear Modem file, just re-flashing the modem did NOT fix GPS issues which plagued a minority of users. I never had the issue, but for people that did have it, they complained and complained. For us who didn't have it, we couldn't figure out what they were doing "wrong".
Someone figured out a a very complicated workaround (going back to stock, getting a GPS lock, then immediately flashing the custom ROM, etc.) And then someone figured out they could share a TWRP backup of their "good" modem for people with GPS problems.
But the @bhb27 Clear Modem file FIXED ALL THAT, for GPS. All you had to do was flash that, after installing a custom ROM.
But for other radio/modem problems, some people flashing the Clear Modem file AND then re-flashing radio/modem is the key.
You can flash them both back to back in TWRP -- the Clean Modem file first, then the radio/modem.
