CM roms and gps

Does anyone know what the issue is with aosp roms and gps? Every one I try can lock on my location, but will not navigate. Google maps/navigation often just says "looking for gps".
I love the new Destroyer rom, but I NEED accurate navigation for work.

Have you tried the fix where you flash back to a sense rom and then type ##gpsclrx# in the dialer. Then flash back to your aosp rom backup.
Worked for me and many others on here.

I'll try that now. Thanks!

It did not make a difference. Here is what I did:
Nandroid restore of a previous sense rom.
##gpsclrx# from the dialer. Enter msl number.
Nandroid restore of my aosp rom.
reboot.
No dice. Was that the correct procedure?

I believe you have to reboot into sense again before nandroid restore, did you do this? It's been a long time since I did the fix but I used the fresh rom for this process.
I did this fix back on like, nightly 6 and it worked great ever since up through RC2.

After dialing ##gpsclrx#, then entering the msl number, the phone automatically rebooted after 10 seconds. I let the sense rom boot up, (koni 2), then went into recovery and nandroid restored the destroyer aosp rom.

When typing in gpsclrx, I'm just typing the numbers that represent the letter, correct? 4772579?

Correct. When you reboot, after inputting that MSL, make sure you verify a GPS lock and even initiate some Navigation for good measure. This is what I did and all worked fine. Some have reported it didn't seem to work but they realized they didn't inititally lock on after the reboot. Then you can flash CM / nand restore.

Thank you so much. I'll give it a shot.

Yeah, hope it works for ya!

I flashed mikfroyo, reset GPS, booted back into mikfroyo, and then opened maps and locked onto my signal, then nandrestore and I had working gps.

This did the trick! Thanks! Gps inaccuracies were the only thing keeping me from sticking with an aosp rom.

1. Download MSL code reader from the market, that gives you your msl code, run it, write it down
2. Backup your current rom
3. Flash a sense rom, don't need to sign in
4. Open the dialer, input##gpsclrx# , enter your 6 digit msl code
5. Restore backup

Prl update

I flashed a sense rom today and updated my prl. Afterwards I restored my nandroid of CM7, and now I can't get my data to work for anything.
Can updating your prl break data? I was coming from a Verizon prl if that matters.

Hmm, I would tend to think that updating your PRL wouldn't break your data, however I'm not familiar with the verizon prl hack, so I'm not sure if the procedures of updating PRL differ from normal. Did data work on the sense rom, after you updated the PRL, before you nand restored to CM? I'd hop back onto a sense rom, update profile and prl again, then see if data works while on that rom. Then try nand restoring back to CM again, and see what happens.

It worked on the sense rom. I just tried flashing back, updating again, and restoring my nandroid...same thing. I called sprint and had them update my services but that didn't fix it either. I thought the problem might have been with my flash so I wiped everything twice and flashed CM7 again. No go.
I'm perplexed.

Go into your Mobile Network data settings, and make sure all the roaming options are enabled, and that data is enabled.
Also, FWIW, format /system, /data, and /cache (Amon_RA 2.3 and ClockworkMod 3.x both have these options), then flash CM7 Nightly 19, followed by the 20110307 GApps. See if you get the same problem.

[Q] Bars randomly drop to 0 bars - PLEASE HELP

Hey guys. I can't stand this anymore. I have tried everything I know. I REALLY need help. I use this phone for work and school project communication and it's crucial to my day to day activities.
-Myns Warmtwopointtwo RLS5 ROM (http://forum.xda-developers.com/showthread.php?t=793471)
-Evo_Radio_2.15.00.11.19_WiMax_27167_R01_PRI_NV_1.90_003 (This is the all in one radio thing linked in Myns thread)
-StockKernel.32
Problem: I am getting intermittent connection. Sometimes my bars on the top will go out completely in a place where I KNOW there is connectivity. It is at random intervals. It will come back after a restart or after I switch from airplane mode and back out again. This is not a permanent solution and it keeps happening to me. It's happened on other ROMs as well!
Things I have tried\not tried:
Installed other ROMS (Cynogen is the only ROM I DID NOT have this problem with but then I lose my GPS capability when I use it...I NEED gps capabilities)
Cleared all the Davlik Cache, Cache settings, then installed a ROM
Installed in ROM, Kernel, radios in different orders. (What is the right order to do it? - I have done MANY different orders all still failing to fix this problem)
Tried other Kernels (Mostly the ones in the ROM threads recommended sections)
I have NOT tried different radios yet (I dont know which to use or where to get them.. or compatibility with ROM I'm using) - Would trying older Radios even do anything?? I don't know...
I have NOT tried installing HBoot updates yet..I noticed it in Caulkins radios thread. What is that? Should I install the latest Hboot?
Hard resetting
Using a different recovery (I am using the one that starts with an "A" now...forgot the name) - I changed it then I used this new Recovery to clear settings..problem still exists
PLEASE help me. I can't stand this anymore.

Well, you've certainly tried quite a bit to get this fixed huh? I experienced the same thing a while back, but it wasn't on Myns rom. I ended up downgrading my radio and PRI, and that seemed to have make the issue better. You should try downgrading to 1.77 pri, and the radio that ends in 09.01. You will be fine on the older radios on Myns, you just cannot use the stock htc 15 kernel that comes with the rom. You need to flash a different kernel right after you flash the rom, before you boot up. That'd be what I would try first. Good luck.

Most, if not all, of us experience the same thing. I tend to think it is network related. You can download and install the Roam Control app from the market. It will give you the option to "roam only", usually on Verizon's network where coverage is almost everywhere. I use it here at home where I basically have little to no signal in regard to voice services.

I agree Doug, that it could be network related. It still happens to me (not as frequently, though) after downgrading my radios. It's annoying none the less!

Like you, I have no doubt that the latest baseband is also playing a role in regard to poor signal strength. Hopefully, it will be rectified when Gingerbread is released.

Oh I need to flash a different Kernel? I tried downgrading older radios but it kept giving me an error...is that why?
Those of you saying it happens to most of us...I never experienced the problem after 1 month of going to Cyanogen ROM...I had it for a full month or longer with no problems at all. Never went to 0 bars where I knew I had signal. Now it happens every day. Before Cyanogen I had the problem and now after. I just switched away from it because I needed GPS.

Keep in mind that it has been reported that Sprint is updating/upgrading their system for LTE. Don't hesitate to call Sprint and see if they can do anything from their end.

When I try to install an older radio I get "Multiple firmware images, cant store radio image, failure at line 2."
I already installed a different kernel. So I am not on stock htc anymore

Make sure you do not have any PC36IMG.zip files on the root of your SD card. Download a fresh copy of the radio and PRI you want to flash and place them on your SD card. Afterwards, upgrade to or flash amon RA v2.3. After upgrading or flashing your recovery, wipe the cache & dalvik cache and then flash the PRI. You will reboot and see the radio update screen. Be patient. When it is done, you will reboot into recovery and see the words "clearing cache". Re-wipe the dalvik cache and then flash the radio. Like before, you will see the radio update screen. Again, be patient and by no means do you pull the battery. When it is done, you will reboot into recovery and again see the words, "clearing cache". Go ahead and select reboot and then you will boot into your homescreen.

Right after I rebooted right at that part where I put an arrow and pressed the button to reboot the screen looked ugly. Like scratchy pink and white lines across it...
It rebooted fine and all and I will test this for a few days hoping everything is fine but that screen looked bad...is that how it's suppose to look?

Yes, it is just graphical noise from the kernel used in RA 2.3. I will PM you the version I use. It does not contain the graphical noise. I have amon RA v2.3 HAUS MOD. A different kernel was used. Check your PM momentarily.

Thank you! I will keep you updated in this thread with what happens and if the problem continues. Really appreciate your help.
OT: That method you told me to flash a new PRI and radio...is that the way your always suppose to do it? (I use to just straight after installing a ROM flash PRI and Radio right after. Not clearing/wiping anything in between)

Your way is perfectly acceptable. I just follow the golden rule: Prior to flashing ANYTHING, wipe the cache & dalvik cache. Doing so can save you unnecessary troubleshooting....

This is mostly everything I can think of that will give you better 3G
My suggestion:
Back up.
Download all latest radios. Check my sig for a link.
Wipe cache and dalvik.
Flash radio. Reboot. (All reboots will take you back into recovery)
Flash Wimax. Reboot.
Flash PRI. Reboot.
Flash NV. Reboot.
Flash a rooted Sense ROM, based on the Evo (this disqualifies MikG, Director's Cut, Synergy and other Sense 2.1 / 3.0 ROMs, because those are based on the Evo Shift/3D (I've had issues with Shift/3D-based ROMs not reprovisioning data). Update PRL. Reboot.
Go into EPST (Dial ##3282#, Choose edit mode), enter your MSL code (download and use MSL Reader from the Market to get it), Data Profile, hit the menu button and choose restore. Just sit there, your phone will reboot and everything will go back to default. Let it reprovision, but when it says "Updating PRL" hit cancel.
##3282#, enter MSL, Advanced, change both Proxy ports to 0, proxy addresses to 0.0.0.0
Hit menu button, "save changes", back out to home screen and reboot
Wipe everything in recovery three times, flash ROM of choice (clean install)
3G Supercharge if you wish

3G shows but noooo data

I updated my friend's Epic a while back to cm10 but lost data in the process. I have it again giving it another shot but still can't get it to connect for the life of me. The funniest part is that 3G/1x signals will be showing at the top along with the up/down activity arrows but no data is coming through. I've Odin'd a fresh copy of FC09, tried multiple roms including going back to CM9 and still no dice. Any ideas?

Check with sprint to see if something is up. If you went to stock and it still doesn't work you could have a messed up 3G radio.

I just did this to my nephews phone
Figured I'd be the cool guy and upgrade his phone and it looks like it lost all his APN settings. Which weren't backed up because the CM wiki didn't mention it...
So now I'm trying to figure how to get his **** working again. He's got a mostly functional cm10 with the cm10 gapps installed and can make calls and text, it says 3g is connected, that he isn't roaming, shows an ip address in settings but can't browse the internet without Wi-Fi.
And now I feel like a jerk

Seqrch the cm wiki for the sd bootable rom... boot into the sd rom after following the directions for unpacking correctly, once booted, update profile and prl... reboot (this will reboot you back to cm10, not the sd rom) and all should be good again..
Edit- you can also achieve this by flashing a tw mtd rom (check development section, I recommend tpr)... back up cm10 in recovery, wipe everything, flash tw mtd rom, once booted update profile and prl, reboot into recovery and restore backup of cm10... this should fix the issue...

If you flash the CM10 modem patch, you can update profile and prl w/o changing ROMs.
