4G Low to No Signal - LG Nitro HD

Hey guys, so I recently rooted my LG Optimus 4G LTE P935 Phone, and put in CyanogenMod 10.1. Since then I am getting very little to no 4G speeds, and sometimes drops completely. I was reading online that this could be due to old fragmented files etc. I am wondering what the procedure is to perform a full wipe/clean of my phone,to remove all files, then just flash the rom back on again?
Thanks in advance.

Do you know what baseband you are using? Sounds like it could be an incompatible baseband.

If I am not mistaken that is a Korean baseband and could be the source of the problem. Go here: http://forum.xda-developers.com/showthread.php?t=1842763
On the first post is a link called download. Click on download and then look for the telus v20e download. Hopefully that will take care of the problem.

Galaxy Nexus x Wind Mobile

Got the phone a few days ago... coming from a galaxy s
unlocked and rooted it but other than that it's a stock telus gn.
i live in the mississauga/bramton area of the gta and get 'no service' quite a bit.
3g is on and off... and the device shows 'away' when in the wind zone.
baseband is KL1, i was wondering if it's worth it to flash a rom so that i can flash a another modem
im sure there are at least a few that are in my position. any help would be appreciated.
You don't need a new ROM to flash alternative baseband radios. Keep your stock ROM.
People are reporting great performance on Wind mobile using the Korean baseband KRKL1

[Q] C spire & Sprint's GS3 similar?

Hello everyone. I am curious to know if anybody with a c spire galaxy sIII tried root theirs using the sprint method? I know the phone has just arrived on cspire and hasn't been out a good week but since c spire's gs3 and sprint's version is of similar variant(sprint sph-l710, cspire sch-710), I was wondering if they would be compatible. Sorry if this is posted in the wrong section but there isn't a main section for cspire and also thank you for your time.

What about ROM's? Should we be using Sprint's CM10 builds or is there some reason that wouldn't work?

make a nandroid and give it a shot
Root method worked out fine for me too. As far as Roms. I tried the paranoidandroid rom and it worked fine didn't get to test the network. I don't believe the TW Roms will work properly as they are based on sprint updates. But cm, aosp, and aokp based Roms should work fine.

I have tried both cm10 and paranoidandroid and neither have working data. of course i am in an area which does not have 4g yet so it might only be an issue with 3g or the prl is not updating with a *228

Just so I'm clear, this is what you're referring to as the "Sprint Method", right?
That's not the website that I found the instructions on. But looks to still be correct.

I just posted this in the other thread but I thought I would post it here just so everyone is on the same page between the two.
Okay. First of all, I didn't think to look at the PRL before I went and flashed the Sprint CM10. But now it says 20005. I restored my nandroid backup and pulled this PRL from my phone with QPST 2.7.374. In DFS Tool, I noticed there was a CSpire PRL 10009. I wrote this PRL to the Phone and am getting much better service on the stock TW ROM.
HOWEVER, I flashed the Sprint CM10 again and the same thing happened. It says PRL 10009, but there is little to no service and when it does have a little service, it is very flaky and eventually ends up with no data connection at all. Any more suggestions or ideas?

I followed these instructions found in the Android Development subforum
http://www.youtube.com/watch?v=XoEVDgjTTdg&feature=youtu.be
I took my GS3 by CS yesterday for the upgrade they sent the text out about. Check my PRL this morning and mine says 20005; not sure what it was before they made changes last night.

Not recommended. You still have the T-Mobile phone so all roms etc. should still be for T-Mobile.
The only thing that you might wanna do different, and one of you more knowledgeable people correct me if im wrong, is to flash a different radio so you can get better signal.
I go to Canada a lot and interchange often between T-Mobile and bell without much issue.

[Q] flashing modems?

The possibility of flashing different modems was discussed in a couple different threads and I was wondering if there was any progress on it. I am on an unlocked e971 on the Sasktel network and their LTE network goes live tomorrow. Sasktel sells the e973 so I am assuming I will be unable to use LTE but my fingers are crossed they support the 2600MHz band. Is this a software issue (still hope) or hardware issue (I'm ****ed)?

Why would you have to send your phone in for repair from just changing the modem? That is weird imo... Back with the Captivate, using the incorrect modem just resulted in no signal. Flash again in CWM with correct modem and you're good to go.

I did some googling and found that Sasktel is using 1700/2100 MHz (same as telus) in phase 1 and using 700 MHz later on. Looks like I will be waiting till the auction for LTE :bad: but on the bright side the development for this device seems to be picking up :good:

I'm not you so I don't know what you tried. But there is definitely a bunch of modems out there and hard to believe that the wrong modem will brick a phone, especially when we got CWM, Download Mode, etc.
Well Chad and Houstonn experimented and both killed their radio.
It's probably safe to swap within Canadian carriers and not otherwise.

As long as there is a Rogers modem and can be done in CWM, then I'd love to give it a try. Obviously you can't connect to the network using Korean modem. They use different frequencies...

Not sure if trolling or stupid.
However, looking at the recent post you made i'll go with the stupid.
I flashed korean modem. I had no network. I flashed back my old modem (It was even the same as i had on my phone cause i made a backup). I could still not connect to network. I Tried different modem. I could still not connect to the network. Houstonn have same problem.
I think i made my sentence simple enough now.

The flash probably broke something else then. Out of all the phones I've used and flashed, not one has resulted in a situation that you are describing. But whatever. I'm just trying to help and suggest things that could have happened or been missed. Clearly help is not appreciated here.

Tnx a lot
They look the same. Psx and cm are more customizable. Looking at the cm thread, seems they are not getting the best battery life. But on psx it is amazing. On any other rom EVER i have never gotten battery life this good.

Dang... No matter what I try, I can't get any network signal with PSX on my F180S. Tried settings and steps recommended by @davevinci to no avail. Also tried experimenting with some different values for those build.prop items related to the modem/RIL/network after reviewing and comparing build.prop files from ROMs that work for me. Nothing seems to do the trick. Looks like I am out of luck, at least for now... Reverted to 4.1.2, which works perfectly.
I am curious, did anyone with a Korean F180x (not E97x!) in Canada or in the US actually make any 4.4 ROM work (not just PSX, but anything)? For some reason, nothing but stock-based ROMS seems to work for me so far. Not a big deal, as I am pretty happy with stock at the moment, but would like to see it working properly on my phone...

Yeah, I can see you are in Philippines. I was looking for someone local here just to make sure we are dealing with the same networks and freq. bands.
The phone says "No Service", no matter what. I did a bit of research on the build.prop lines that you are referencing, and tried changing them to different values (your settings seem to be for CDMA with LTE only), but nothing worked so far. For the time being, I am giving up experiments, unless someone with the same phone on Canadian or American GSM carrier can tell me what exactly they did to make it work.
Like I said, it's not a big deal -- I am not desperately trying to make 4.4 work, but rather just curious about it...

Looks like you added this question later, I didn't see it when I responded... Actually, I tried both. First, I just made changes and rebooted. But later, every time I made a change to a build.prop, I updated it in the zip package, and did a new flash every time after a full wipe.

Hey, thanks for following up! But, like I said, I already tried several times a full wipe (data, cache, system) before flashing the ROM with tweaked build.prop.
I just need a stable working phone now, so I wont be experimenting with it for some time...
