[Q] Lost network after baseband flash

I bought a Canadian Optimus LTE P930 unlocked off ebay. I have no idea which carrier it was originally locked to (most likely either Bell or Telus). It came with Gingerbread, and I immediately rooted and installed CM10 M2 snapshot. My carrier is Fido (subsidiary of Rogers) and my Fido sim card worked on Gingerbread, and was working on CM10 until just now. When it was working, it showed up as Rogers rather than Fido, but that's not unusual for custom ROMs.
After seeing some suggestions that changing the baseband could help with the random reboot problem on CM10, I went to this thread: http://forum.xda-developers.com/showthread.php?t=1842763 and proceeded to try out the AT&T V18f baseband (from http://www.mediafire.com/?nniz00g7c7b3p). I installed the zip through CWM (I have the latest, 6.0.something).
After rebooting, my phone was completely unable to access the cellular network! I tried manually connecting to Rogers from the settings menu - no dice. I tried locking the phone in 2G mode and then reconnecting - no luck. Then I went back to that mediafire link and tried out every single baseband with the exception of P936 ones, and still no luck.
Finally I tried reinstalling CM10 from scratch (full wipe and everything) and still no dice even after trying all of the above again. I even reset APN settings to default.
I have not tried downgrading back to stock gingerbread (actually, I can't even find the ROM, other than in the Unbricking guide). I hope I won't have to end up buying an unlock code for a phone that came unlocked in the first place.
Due to my own stupidity, I did not take note of what the baseband was on my phone before I tried flashing a new one, so I really don't know which baseband is supposed to be working. I fear that this baseband experiment ended up re-locking my phone or something.
I have tried my Fido SIM in my other phones and it works, no problem.
Does anyone know what I can do? Thanks for any possible help.

That sucks that you are having a problem with the basebands. Lots of people have been using my zips and literally no one has reported any issue with them before, so it seems very strange that it would have caused something weird to happen on your phone.
I will say that I haven't had a chance to test the zips yet with the new version of CWM (6.0.1.5). Probably the first thing I'd try is downgrading CWM to 5.8.2.0 just because I really have no other idea why you'd be having that problem. Maybe someone else can chime in and let me know if the zips are working properly with 6.0.1.5 so we can rule that out as a possibility, but in the meantime it's something easy to try.
To downgrade, open ROM Manager, and scroll down to the very last option from the main menu. Select 5.8.2.0 and it will flash it for you. After that, reboot to recovery and try flashing one of the basebands again.
I just tested it with CWM 6.0.1.5 and it worked properly on my phone, so I don't think this is the cause of the problem.

I have just tried using the P936 basebands, and they did not work.
With every baseband I tried, my phone can detect that Rogers, Bell, and Telus networks exist (the latter two show up as a weird number on P936 basebands) if I use 3G mode, but can't connect to a single one. If I toggle 2G-only mode, it only detects the Rogers network, and still cannot connect. This is the behavior you'd expect from using a foreign SIM in a network-locked phone. From this, I think I can conclude that both the phone's radio chip and my SIM card are in working condition.
From what I have read, baseband flashing should not affect the network lock on a phone right?
If I can't find any alternative, I'm going to have to use the unbricking guide to downgrade to Gingerbread, which I hope not to do as it's a lot of time wasted, and I honestly don't even know if it'll solve the problem.
edit: to add, I don't have an LTE sim card (was planning to get one later this week) so all attempts to connect to a network are only 3G and 2G,

I don't know because I haven't ever had any reason to unlock my device.
Unless it has changed since the last time I tried it, CM9 and CM10 do not have support for unlocking your phone in the case that it is locked (but will work fine if the phone is already unlocked). Let's assume for the moment that your phone still works fine, but was relocked by installing a new baseband for whatever reason. If that's the case, then you must install one of the LG official ROMs in order to unlock the device again.
You don't actually need to unbrick though. I'd suggest that you take the system and boot images from the unbricking guide, push them to the device using adb, then force reboot the phone -- that way you won't lose CWM in the process.

Yeah that's true, pretty much all custom ROMs don't have the SIM unlock feature and that's fine. I am assuming my seller on ebay just entered the unlock code on stock Gingerbread before shipping it (at least that's what I would have done).
I guess I'll flash on an official ROM tonight. Do you know where I can find a CWM-flashable stock GB ROM? The unbricking guide looks pretty darn complicated and I would prefer not to spend too much time on this, since my phone isn't bricked.
edit: Let's pretend for the moment that flashing stock GB will solve the problem and restore network access. Is there a way I could back up the baseband afterwards?

I can make one fairly easily, give me a moment... Edit: nevermind, it will take forever to upload it.
Here's what you can do:
Download system and boot images from here: http://forum.xda-developers.com/showthread.php?t=1597488
Then from either terminal emulator or adb shell, do this:
Code:
su
dd if=/sdcard/boot.img of=/dev/block/mmcblk0p8
dd if=/sdcard/system.img of=/dev/block/mmcblk0p27
Then force shut off the phone (remove battery or hold power button for long time), and before you let it boot up, go to CWM (by powering the phone holding the volume down button) and do a factory reset from CWM, then reboot the phone normally and you should be in business.

Thanks a lot for your help, drumist. I am downloading the files now and trying my luck! Be back with the results later.

Oh, one other thing. I'd go ahead and flash the Bell v11a baseband before you do anything else. That's probably the one you want to use with that phone, and you don't want to flash another baseband after unlocking (at least, that seems to be the case).

Got the stock AT&T Gingerbread ROM running - and the first message I got was asking for a SIM network unlock PIN!
Looks like flashing the baseband indeed re-locked my phone (I didn't think this was even possible).
edit: Called my ebay seller and got the unlock code that he'd used before sending me the phone. All is well!
thanks drumist for saving me a lot of time with your "simplified steps".

This is all very strange because I also have an unlocked p930 but flashing new base bands has done nothing to affect my unlock.

Yeah, a lot of sites say unlocks are permanent due to how they affect hardware switches. Well, half an hour later I'm finally back on CM10 with network enabled.

Just tried flashing the V18f baseband from AT&T. This time it didn't affect my network.
Weird...

Push CWM via ADB?

I successfully flashed the Panama Stock 980H ROM, and I am going to root.
If FreeGee doesn't support it, can I push CWM via ADB?
I haven't done it, but I know it can be done on some devices. Has anyone done in on the LG OG Pro?
FWIW, the data DOES throttle correctly when not using the AT&T modem! (success)

I'm running the Panama Rom on my e980 AT$T and have CWM installed via freegee....:what:

It just says my software is not supported.
Edit: I didn't know you didn't have to disable the security to install CWM.
It worked without doing so!

Hi there all, want to first say thanks to all the devs and everyone on this board for all the cool work with LG phones. I'm new to AT&T (from Sprint) and GSM phones after 6 years of HTC phones and roms. Right now I'm on the trial period trying to decide if I will keep this E980 or return it and go with the HTC One, but I really like having the micro sd card over no sd card slot with the HTC One. Anyhow I wanted to post my rookie questions here because I am stuck, looked around and read everything but still unable to get CWM installed.
So far I have
1. Successfully flashed the Panama Stock 980H ROM
2. Successfully rooted
3. Installed FreeGee pro tried clicking unlock "sorry your varient is not supported" when I click install recovery I get FC, tried again this time selecting do not disable LG security, same thing FC? So my question is what dumb thing am I doing wrong, I have to be missing some detail right? Thanks
EDIT: Must of had a bad install the first time, uninstalled, reinstalled, installed CMW no more FC's or errors

Don't try to disable security. Everything else works. Just say I decline or No or whatever.

I believe the Freegee servers are down at the moment. I was unable to install any recoveries yesterday. But the developer is working to update it, so I expect all will be fine soon.
Regarding the unlocking process: From CWM, you should be able to restore an AT&T stock rom back up. Then you can unlock and try your luck with AOSP roms.

[Q] G2 LS980 (sprint) Roms

Ive been looking around the roms on the sprint section to find another stock rom that is already GSM unlocked so it can be used on t-mobile, like the Cyanogen11 one but cant find a definitive answer while reading through the roms and change logs of the roms. i know this might be a stupid anwsers and sorry if it is, but im not used to dealing with sprint phones and the TC method never worked for me when i have tried to do it and i have done it. any suggestios. thank you in advance.

I think for now it's a test it and keep a list of what works or if you try some post your results here I'm sure we are not the only two wondering this. cm11 works good great data speed for me on att but would also like a stock option.

The TC method never worked for US carriers. Have you tried the build.prop edit method? Should not be dependent on the rom. For a stock rom I find OpTimuS DE excellent. I used it previously with the build.prop unlock and now with the permanent unlock (but I'm in Canada).

Use rom toolbox (or similar) to edit your build.prop... ***case sensitive!!!!***
ro.build.target_operator = SPR
reboot
ro.build.target_operator = OPEN
reboot, then
ro.build.target_operator = spr
reboot
The last one (spr) is done because you will get system UI crashes if you leave it as OPEN.

Blah, that didn't work, even with the sprint Sim. When I use the LG tool to go back to stock on picks up some service with the sprint Sim.

I don't follow. Why would you have a Sprint sim in the phone?? If you do this with a Sprint sim in the phone you will lose data. If you flash a rom or back to stock, you have to edit the build.prop again to activate gsm.

Haha sorry I didn't mean to make that confusing. But it didn't work with the T-Mobile Sim either. The only time I have been able to get any type of service bars instead of a red x over it is when I put the sprint Sim in and go back to bare stock

Actually now when I put my T-Mobile Sim back in, it shows all the service bars Grey but can't choose and operator or send a text.

You can use the app Tweakker to enter your APN settings.

the phone wants to resort back to cdma for phone service, grab an app called telinfo from the play store and use it to set your phone to GSM (auto PRL), then set your APN to get data working, best of luck!

Cricket working on sprint lg g2 h+

Hi everyone, so here it go's, ive been working with android devices all the way from my first android device(phone) the THE FAMOUS DROID X, since then on to a Motorola Xoom, Been theming and messing about with Linux OS's.
I purchased a Sprint LG G2 not really looking into the device because ive always depended on XDA and its entire community to come out with a hot fix, anyways I have Cricket Service and didnt realize the SIM had to be unlocked to work on other SIM cards, Since the stock ROM wouldnt let me on the Cricket Nework I downloaded and installed CM11, after installing messing around with Mobile Settings and such I got the Text (not mms) and Talk working however without data, so i knew the APNs werent working correctly, to make this short, I took the APNs from my moms Galaxy s4 (sold by Cricket) so the 4g worked on her phone, the attached files i put in the system/etc folder after that went into the settings networks selected 3g, and then added APN now when entering APN (access point names) i just entered in name and apn and saved it, then went back in and edited the rest and here are the screen shots

well the SIM it self only cost 10 bucks but the service and activation was 50 bucks. i think that includes registering the phone as well. i hope everything works out for you,
when i bought the g2 i really didnt know nothing about it, once i bought it and found out it had a LOCKED SIM, i went right to XDA for a quick work around. after configuring the phone and APNs very happy with the results for my g2(ls980)

sorry for the late response maybe u could help me to id like the sprint rom stock but i haven't figured out a way to get the apns sticking on zvc, however to install a t mobile (ported version for ls980) rom or any other, first root the device, with ioroot25, then install a custom recovery twrp with autorec in the play store, after reboot into recovery use trwp app in the play store, once in recovery go to wipe and wipe system,data (NOT INTERNAL DATA) davik, and cache locate the rom zip, and install, make sure you have the latest firmware installed first which is i believe 4.4.2, zvc. also the devs add a link to the whitelines fix which you will need

honestly, i am not sure how you did this.. you sure you have a ls980? from what i have read, you can not put a us gsm carrier on a sprint phone..only international

Can I flash ROMs intended for other note 4 variants?

I'm asking this question because the current build of CM13 for the N910V is underdeveloped at this time and I was wondering if I could flash CM13 for the SM-N910T or the sprint variant without any modem issues, etc.

Do a nandroid using TWRP and try it out. I've been testing different ROMs myself. I don't care for ASOP. Kind of ugly and useless without stock Samsung Apps. But I have tested MIUI, and a few other stock based ROMs found in the international Note 4 forum.

Just backup your EFS, Modem, and Boot partitions for sure. If you get a successful flash, immediately use TWRP to restore those partitions and you should be golden. Might also have to edit build.prop to avoid Play Store issues.

Has anyone tried a Sprint TW rom 6.0.1? I may give it a whirl and see if it works.

what roms are available to flash?
Hi there,
I find myself in an unusual(i think?) situation in that I have the verizon Note 4 but i live in Ireland. Now while the phone is sim free for the most part, Data does not work here without a verizon plan obviously and it would have to be a roaming plan so I would'nt even think about purchasing one. So i've been waiting for an opportunity to root my N4, now that there is a method I'm just wondering if I would be able to flash a stock Irl/Uk rom to my phone, or another rom that would allow me to have data and spen features. I would like to find out if this is possible before I attempt to root. My phone is on 5.1.1 and is the BPA1 version. Any help much appreciated, thanks.

Pending you could add the correct APN for whatever carrier you will be using, you should be fine. I purchased 2 of these devices nearly 2 years ago. I'm on Verizon prepaid and my wife has been on T-Mobile every since.
Funny thing is I didn't have to set her APN manually. The phone did it automatically the day I put her SIM in. Now she doesn't get the full potential of LTE speeds and MMS is a bit kwonky, but it works.

Thanks for the reply,
do you mean add the APN settings after i've rooted? I'm intending to flash the vodafone 5.1.1 IRL Stock Rom if it's possible, I already tried adding the APN settings and it does not work(unrooted) due to bootloader being locked and like i said i would need a verizon roaming plan to be able to use data. So if I get root and flash IRL vodafone stock rom, will I still have an unlocked phone or not? I'm not an expert in this but I would assume the phone would then be locked on the vodafone network yes? Or would it remain unlocked to any network? So just to be clear, what i would like to know is 1. will I be able to flash a stock rom from Vodafone Ireland once i'm rooted 2. If I do manage to flash Vodafone stock rom, will the phone still be unlocked or locked to vodafone? Any help much appreciated. Thanks.

Unlocked sim and unlocked bootloader are different. The phone is sim unlocked from the factory and can never be sim relocked (for lack of a better term). So to answer #2, the phone will not be locked to vodafone.
For #1, I seriously doubt you could odin a stock vodafone rom to this phone and even if you could I'd highly discourage it. If the file contained a bootloader, it would lock the bootloader and could potentially brick the phone. I would recommend unlocking the bootloader, flashing TWRP recovery, rooting (or flash a rooted rom), and add your APN's. If the stock rom is blocking you from adding APN's there are hacks to get around it once rooted. I used to use an app called APN Manager that you install as a /system app that would let you change APN's as you wish.

Any Touchwiz rom should support the S Pen. I believe the Paul (5.1.1) rom does. There's a Note 5 rom that should support it. Just stay away from CM13 or any AOSP roms and you should have S Pen support.

Not such an unusual situation hello from Ireland also a proud verizon note 4 user myself. Meteor and Emobile for me. Data works fine. Let me know if ya need any help.

I am also curious about this situation. I got an awesome deal for my 910v; brand new unopened for 280usd. Only problem is T-mobile sim doesn't get service, and it seems people have lost T-mobile service after upgrading to 5.0. So now I'm stuck with my aging S3 and this brilliant phone just sits there. Fingers crossed that johnboy sees some good results T.T
