no 4g signal now - LG Optimus G Pro

I've been flashing roms and noticed my gps wouldn't work yesterday. flashed a couple other roms today and I can't get 4g signal, it just keeps saying H. should I be flashing a modem after each rom?
edit: I restored a stock backup I had before I started flashing roms and my 4g lte signal is back, no more H icon. what could be the problem? or solution?

What's your carrier?

It's probably not the modem. CM/AOSP ROMs don't even flash modems. If you look, there are no basebands in the .zips. Not only that, but there's a growing body of evidence to suggest that modem/baseband flashing does not work at all via CWM/TWRP anyway.
Probably it's related to the RILJ.
The Open Source RILJ isn't as optimized as the stock one, and when you flashed back to stock, you got the stock RILJ. You baseband didn't change.

so would that mean I should restore my stock backup and then flash the rom I want to install? does flashing rom after rom complicate things at all? or is there a way to completely start from scratch kinda like restoring the stock backup
this is on the instructions to flash cm 10.2 "Make sure you install this MODEM. Without it, you'll have a phone that never deep sleeps. ever." is this true with all roms or just cm 10.2?

You can go back to complete stock using the lg flash tool. But idk if it'll help.

That's for AT&T customers, and I think why it works is that it hooks into the part of the custom RILJ that is optimized for AT&T.
I'm not on AT&T and I've never had a problem with deep sleep, with or without flashing modems, and either way, the modem never actually changes.
I keep a clean stock CWM backup both on my PC and my internal storage on the device.
I frequently bounce between ROMs, but I always restore to stock before doing so.
There's a lot of strange behavior with sd cards, directories, etc. when doing so, however, because the recovery creates a mnt/storage directory that cannot be seen by the PC when running custom ROMs at all. You have to do an adb pull to backup from the directory. It's a PITA.

[Baseband] Flashable .zip APQ8064T/MDM9X15M

Just in case anyone is interested, I pulled the APQ8064T/MDM9X15M modem via adb and put it into a flashable .zip
I have never seen this modem anywhere, so I thought I'd share it for those who might want it. If you are on AT&T, you don't probably need or want to flash it, but other networks in other parts of the world, including parts of North America (Mexico) and all of Central America, etc. do use it.
It's direclty from the Panama Stock 980h ROM.

I don't think so. I think what's much more likely is that the modem flashing ability on this device via CWM is non-functional, and anyone who thinks they've flashed a different modem that way actually hasn't successfully done so.
I have been wrestling with the RILJ issue related to my network, and as I understand it, in CM/AOSP, the modem string is just a placeholder. It's not a reflection of the actual modem, but in Stock ROMs, I don't think that's the case, because when I was on Stock AT&T, my modem behaved differently than when on Stock Panama.
The modem.img in your zip is larger then the one in my AT$t V10G zip also...
Niw im back on stock AT$T and this is my modem#

hmmm.....my F240K shows exactly the same baseband on stock i.e. APQ8064T/MDM9X15M....wonder if they are the same...
also if CWM is not flashing modem properly...how can you be sure that you have flashed it?
in CM/AOSP ROMs if modem string is placeholder is that because these ROMs don't flash a modem?
I noticed that the panama modem says AP08064T and the stock AT$T modem AP08064.
The "T" is he only difference in the displayed name. So I can see how it might be confusing lol.....

My suggestion would be to flash the hacked TWRP recovery by MadMack, it can be found in the CM10.2 Unofficial thread. I have used this recovery from day one and have had no problems whatsoever.
Link to Hacked TWRP by MadMack -> http://forum.xda-developers.com/attachment.php?attachmentid=2250186&d=1378908893
It is my understanding, that this recovery is for CM or AOSP based ROM's. I think you must use the CWM or TWRP that are included in FreeGee to flash the Stock ROM variants.
I installed the hacked TWRP and my modem still doesn't change when I flash a different modem.

I have 240L and I really hated the call to korea and other korean network apps on my phone. I wanted to flash some basic stock rom like panama or telcell. but whenever i flashed stock i didn't get my modem to work so I used cwm to flash modem. I have used LOKI recovery and one another apk which is available for download on xda.
In panama and telcell i do get the signal but whenever I tried to make a call my phone restarts. I tried plenty of time then I got tired and flashed a custom rom from Lamhoang ... its working fine but I dont' like the HKFriend kernel its slow!
I still wish if I could get the stock original rom to work with some flashable modem....
one more thing I have 32 gb phone with SD card and in some stock roms i get the 32gb rom but i never got my sd card working.
Thank you this modem save my life.

That question remains unanswered, but the best evidence suggests that the modem is not flashed via recovery in either CWM or TWRP.
I have a chance to pick up another E980 tomorrow in the afternoon for a pretty good price in my area, and if all goes well, I'll be back to the LG OG Pro.

[Q] need expert advice and help...

hi GUYS!! i flashed my GT-7100 to stock rom 4.1.2 so i can update my phone to 4.3 when the official update comes... but after i flashed it..and check my notification it says emergency calls only.... and when i connect to kies it says your blah blah blah is not supported to initialised... i have correct IMEI and S/N... im from the philippines... any guys have idea? how to fix it.? im really in need your help.. God bless!!! thank you in advance....
I wouldn't recommend updating to 4.3 officially as it comes with Knox in the boot loader and it cannot be removed or downgraded. If you were already using a custom ROM then you should go back to that and then wait for a custom rom based on the new firmware but without the bootloader. You may have to flash the 4.3 modem at some point but it is possible to do this without the bootloader in Mobile Odin. I'm not really sure why flashing that stock ROM didn't work but you should be able to go to a custom rom again without issue as long as you have your IMEI. If you feel you must do the official update then just make sure you do some research on the new bootloader first. As far as I know it offers no advantages to an average user and it does have some disadvantages.
Edit: for your other issue I would start with looking at the baseband as cellular issues are normally related to that.

thank you for your response sir.. you think it can be fix my problem by installing other custom rom?
Well if you had a custom ROM running before and that was working then it is likely that it will still work. If it doesn't then you can always flash to stock in Odin again. Its very unlikely that you'd end up worse off since youll just have the same issue on a custom rom if it doesn't fix it. If it doesn't fix it then it is mostly likely related to the baseband because that is one of the few things that remains the same between a custom ROM and stock since you should be wiping data and cache when you flash a rom and it completely rewrites your system. It may not fix the issue but its definitely worth a try and if you decided not to upgrade to the 4.3 bootloader then there's not much need to be stock in my opinion. Stock offers very few if any advantages over custom roms. If you need high stability then just use a ROM that is based on the stock ROM, they are almost always bug free because they only add things like root, deodex, reboot menu, zipalign, performance tweaks, etc. They don't have to deal with drivers or source code like on AOSP roms so they are much easier to make. It may be worth a factory reset now on the stock ROM too if you didn't do it after the Odin flash. Sometimes old data from another ROM can cause issues.

How do I go back to stock? Not stock modem.

Okay so I want to flash back to stock but I realized that my bootloader is not the stock one. I flashed the modem to the newest one before. My bootloader is I747MVLUEMK5. I've heard people sat that i cannot go back to stock just straight flashing with Odin now that I have a different modem. What procedures do I need to take to flash back to stock?

That is the correct one, Backup everything you need off your phone as Odin will wipe everything. nLeaving an external SD in is OK, but the internal memory will get wiped.

I've only used stock and CM11 so far since 4.3. The I've not tried Liquid Smooth but Grievous ROM is pretty good. It's the ROM currently on my wife's phone. It is white themed Touchwiz which was my biggest selling point.

I don't think that is compatible with the i747m no?
Oh and also, let's say I want to get Liquid Smooth onto my phone but I currently have Quantum. Do I have to flash back to stock with Odin and then install the Liquid Smooth ROM? Or can I just go and wipe the system now in recovery without going to stock and then install Liquid Smooth in recovery?
Grievous is compatible with the 747m. Im on 747m Bell. You just need to flash a modem and kernel to get data and wifi to work. As far as liquid smooth, you do not need to go back to stock. Installing the ROM and then wiping should work. If you do find that you ever flash a ROM and have WiFi issues, kernel is likely culprit. No data is usually due to a modem. These seem to be more often with new ROMs and most development based off AT&T phones.

[Q] Need Help Flashing a ROM

Hi guys, sorry if this is stupid. I've flashed ROMs to 3 or 4 phones before this one and didn't have any issues with them, but this time around it doesn't seem so easy. My phone is a virgin mobile galaxy s2 (d710)
My phone has been rooted for a while and my stock ROM started randomly freezing up on me 4-5 times/day, so I finally decided to flash a ROM. The stickied post says to use odin mobile to flash to GB - EL26 Stock w/ CWM then to flash the ROM I want. Any ROM I tried flashing gave a status 7 error and aborted, EXCEPT for one ROM, and on that one I didn't even have working 3G? I believe this thread implied doing it any other way would be a hard brick.
I finally ended up using samsung's official upgrade tool in download mode to flash back to stock ROM, but it would be nice to get a custom on now that I've put time into it.
Can anyone point me in the direction I need to go?
Thanks
EDIT: I'm currently on the 4.1.2 stock ROM
http://forum.xda-developers.com/showthread.php?p=50070702
I'm guessing you're trying to flash a KitKat ROM? Using Mobile Odin and EL26CWM will work when flashing 4.2.2 (and under) ROMs, but not KitKat. You'll need the last Blasphemy 6.6 kernel (just for the updated ClockworkMod), located in Original Development, for that.
In your case, you'll probably want to flash FJ12 or FL26 (if you can find it) modem zips, as you're on Virgin Mobile, and those are ICS Virgin Mobile modems, which you'll need to have working data/internet on Any AOSP ROM (JB modems won't work).
And this guide is assuming you're completely stock JB firmware, not rooted.

Is there a reason why you have to flash one recovery just to move onto another one? Would any recovery work installing any ROM? I'm a bit confused by all these different recoveries, since my last phone only needed one.

On this device, recovery comes bundled with the kernel. When you flash a ROM or kernel, the recovery that was on gets overwritten by the recovery that comes with the ROM/kernel you're flashing.
The reason everybody started using EL26CWM (gingerbread kernel) was due to a bug in the stock ICS firmware that was causing some people's devices to be permanently bricked when doing a factory reset.
Status 7 error when flashing is usually due to using a recovery that's too old.
So to answer your question... No, there is no "be-all, end-all" recovery for this device. Sorry [emoji20]
Glad you got it working though

Thanks for the help. Now that I'm running CM11, I don't have visual voicemail and it looks like I can't receive MMS.
Serious props to the people that use custom ROMs that aren't driven insane by bugs, I'm irritated by it already.
Know of any fix?
I don't know about visual voicemail... I'm flashed to Cricket and just use the built-in voicemail statusbar notification. Have you tried pushing the apk manually? I'm pretty sure I've seen Virgin Mobile fixes here in the d710 forum.
As far as MMS goes, have you tried messing with the APN's? I don't think MMS will work as-flashed, out-of-the-box for you without modifying them for Virgin.
If you're getting annoyed by bugs, have you given stock, rooted deodexed GB28 a try? When i get the TouchWiz itch, I run deodexed GB28, along with Agat's 1.3 kernel, TD's AIO mod, and Missing Link mod (both found in Themes and Apps of this forum).
I'm currently running Slimbean build 7 (4.2.2) as it's super lightweight, stable, and has good battery-life.
Sent from my SPH-D710 using Tapatalk
Do you know where I could find the voicemail apk?
Also, where can I mess with the APNs/what would work there?
The only reason I want a custom ROM at all is to be on KitKat. It honestly disgusts me a bit that google hasn't standardized versions....I don't get why every phone needs it's own ROM and never gets updated....
Thanks man.
Edit: I did find a MMS fix and visual voicemail all in one zip, but flashing it screwed the phone and I had to restore in recovery.
As far as editing APN's, I use Nova Prime launcher to create a shortcut on my homescreen to access them. Create shortcut to Activities/Settings/APNs and make your edits there.
Have you tried extracting the contents of the zip and manually applying those changes? Sorry but I wouldn't know anything else about configuring for Virgin. Maybe you could ask in that respective ROM thread, as I'm sure there are Virgin Mobile users there that have everything working.

Thanks for the ideas, I'm a bit slow sometimes when it comes to android/linux. I pulled the apk out of the zip, installed it, that's working fine. I just need to find a fix for my MMS. I can send but not receive.

Just for clarification, if I want to flash a new ROM when I'm already on a custom, do I need to use odin mobile to flash back to that GB rom with CWM before I flash the recovery and new ROM? Or can I just wipe and flash new recovery from the one I have now?

If the new recovery you are talking about is safe to flash from...and the one you are currently using is safe to flash from...then you can just reboot recovery and wipe cache and dalvik, then flash new recovery and then reboot recovery. Now you will be on the new, safe, recovery. So do your wipes ( data, cache, dalvik cache and format system ) and flash the rom.
If you want to go the mobile odin way..in case the recovery you currently have cant flash the new recovery you need, in order to flash the rom of choice..which im assuming is kitkat. As it needs the most up to date recovery to flash properly.
Then i have a simple guide you can follow to flash a safe kernel/recovery, in which you can then flash the newer recovery for flashing the rom you have choosen.
Link to guide. Post 5 is what you need to read.
If this sounds complicated or confusing..please post a link to current rom you wish to install and i will read the op and point you down the correct path.

Fyi.. I think jdsingle made a virgin mobile rom a while back.

Thanks, I looked for jdsingle and only found posts for 3D Evo I believe; no activity since 2011?

It was made for JB but it's a start

Yeah, I tried that one, it continually crashed my launcher every 3 seconds, had to reflash the ROM. It did give me the voicemail apk I needed though! Really if I could just get flash instructions for going from one rom to another, I'd be set probably.
Have you tried applying the changes and setting permissions in the zip manually, like with Root Explorer?

No, I'm honestly not sure how to do that. Linux's file structure is confusing to me. Granted I'm also having wifi problems on this rom too, it disconnects all the time.

It honestly isn't too difficult at all. All I see in the zip is a new apns-conf.xml (permissions are rw-r-r), 2 build.prop edits, and the deleting of telephony.db located in /data/data/com.android.providers.telephony/databases

Latest Modem and Kernel from COH4 update

Since I didn't see anyone pull the modem and kernel from the last stagefright update in Sept., thought I'd do it for the few of us that still have this old device.

Was there an OTA for T-Mobile? I'm currently on a AOSP Rom.

Yeah, but you need to be on a stock ROM to get the OTA, or you can download the whole ROM from sammobile.com. It's a security fix for stagefright. I just wanted to try the new modem and see if it made any difference. I won't be able to test the kernel, since I switch back and forth between a 4.4.4 TW ROM and 5.1 CM ROM.
Appreciate the info, have you notice better signal with the new radio?

Maybe a little better signal (?), but basically the same. Haven't been on it real long, I'll have to see if the standby improves after I've been on it a while.

Are you dual booting? Is it possible?
Warning, don't flash this modem. I did and it killed my baseband. I tried flashing 3 other roms which wouldn't even finish booting to my phone before I finally realized it and flashed my original modem back and all was working again.

Working fine on mine. Did you maybe get a bad download? You could maybe try downloading again?
Which modem did you go back to?
Flashed fine and so far no issues. Previous user might have a bad download or different device.
Flashed via TWRP today.. I had no service after reboot but did another restart and it was working.
Don't know if its any better than the previous modem version but will give it a try. thx
Working great here no issues
With old bootloader md1 4.1.2 with ROMofTHRONESv1.0

You caused the problem when you altered the stock ROM. From your thread about it here (http://forum.xda-developers.com/note-2-tmobile/help/recent-tmo-ota-update-bricked-wifes-t3245890), you said "Had her note 2 with stock 4.3, Rooted it last year to titanium backup and uninstall a couple bloatware apps. " This is what caused your problem. It was no longer a stock ROM when you remove apps. I know it doesn't seem like it would be a big deal, but it is, and you found out unfortunately

That's kinda what I was thinking had happened.
I suppose I shouldn't blame the OTA. I just noticed someone else had issues with it too.
so to the people that actually flashed this new modem and kernel, is it working better than previous iterations?
question:
I flashed the C0H4 modem on note 2 (nameless lollipop rom) seems ok...
DO I have to also flash the Kernel ? is there an advantage to flashing the kernel? thx
Hello! Thanks for this! I flashed this over TWRP 2.8.7.1, and wiping my dalvik cache. My phone's originally T889UVALK8 (16gb SGH-T889 t0ltetmo) and the signal drops but after flashing this (C0H4) the signal greatly improved, although I'm having some signal instability since I'm supposed to have full bars because my house is just in line of sight, 2km from the tower. Also I think I'll do a clean install of another custom ROM since I'm using the CM12.1 t0lte nightly, and maybe this affects my signal (I know I'm stupid for doing it but it works).
Welp. After rebooting, the phone lost signal again. I have to do a wipe of dalvik cache to restore my signal. I guess I'll try using another ROM instead.
Upodate: I may be experiencing hardware issues. I have yet to flash back to stock since my phone's signal drops. I can't flash the firmware because it says 'zip signature verification failed.'

BUT, "yours" seems to be a completely different phone! It says Galaxy Note 4, SM-N910C...
What's up with that?!

It's just the ROM I flashed that makes it say that. That ROM is in my signature... DN4
