[Q] Issue with ##GPSCLRX# for GPS on CM7

Hey guys, I need a bit of help. I have been using CM7 since build 0, and have been having hte GPS lock issue as everyone else has. I finally got around to going back to a sense ROM to clear the gps using ##GPSCLRX#. When I put that in it asked for the password (MSL code) and I accidentally hit ok, finger slipped. It said password incorrect and I'm not sure if it cleared the GPS or not. I tried to do it again, but when I type in ##GPSCLRX# it just disappears and the password window doesn't come up anymore.
I tried going back to CM7 and then back to a sense ROM, and I can't get that window to pop up again. My GPS still isn't locked consistently, just a quick lock every now and again, so I don't think the clear worked. I don't know how to clear it now.
I tried doing it on Myn's 2.2 and the stock ROM.
Today I did a full wipe and installed a fresh Myn's, and when I type in ##GPSCLRX# it still just disappears from the box, and it never prompts me for a password.
I would really love to get the GPS up and running, because other than that I love cm7. Appreciate the help. If someone can get my GPS up and running well I wouldn't mind donating a few dollars to a beer fund or whatnot.

CM7 RC1 is supposed to have the GPS issues cleared up.

Did you try a factory reset?

RC1 still does it.
I did a full wipe (data/cache/dalvik) when i installed Myn to do the clear, it still wasn't working.
Data wipe via clockwork is the same as factory reset, right?

Maybe this won't help, but you can try unrooting.

Any other suggestions?

Clear Data/Cache on the Dialer in Menu | Settings | Applications? Not sure what else this might muck with.

flash back to frest rom.
copy the attached epst.apk using root explorer to /system/app
when it asks to overwrite accept then install it.
your ## codes should work again.
you can also install 'gps status and tools' and clear the data there

After I went s-on and ran the latest ruu, I had to reapply the GPS fix after I rooted and loaded cm7. I couldn't get the GPS fix to work in Caulkins 1.8. It would reboot and hang at the white evolution screen. I used a rooted copy of the latest stock Tom and everything worked great.

This worked, however I still can't get the GPS to lock. :\
It seems like now I can't even get the GPS activate. If I turn GPS on the icon never comes on in the notification bar. It seems like its only trying to get a lock using the nearest tower or satellite or something.

EVO GPS not locking in GB 2.3
I did a little more research and it turns out that this is a common problem for anyone moving from 2.2 to 2.3 on evo. I found the fix by doing a GPSCLRX from my rooted stock sense rom.
0) Download the 2.3ROM and optional google apps to your sdcard; place it somewhere you can find them when in recovery
1) Download 'msl reader' from android market, run it and record your msl or call Sprint and beg for your msl number and record it for later.
2) ***MOST IMPORTANT PART*** you have to do this from a stock sense ROM. If you made a backup prior to your initial install of a custom ROM just restore it if not get stock ROM from: http://forum.xda-developers.com/wiki/index.php?title=HTC_Supersonic/ROMs
3) Once your stock ROM is up verify your GPS works and locks (GPS toolbox or Maps etc..)
4) With your GPS on; Open dialer and press ##GPSCLRX# or ##4772579#
3) When prompted for the password input your msl code from step 1
4) Phone will reboot in 20 seconds
5) Reboot into recover (power button + down volume)
6) Wipe everything and FLASH 2.3ROM + latest gapps

I'm having GPS issues as well. I tried a similar instructions yesterday except I didn't test my GPS when I restored my stock ROM and turn on GPS during GPSCLRX. If i back up my CM7 rc3 now before I try this again can i just use the restore feature again after unlocking GPS or do I have to wipe and manual flash?
** EDIT ** I'm new to this so I want to add that I'm using the SavagedZen Kernel. Do kernels affect GPS? I haven't read that it does but just wanted to add it to help troubleshooting. I restored to stock ROM and confirmed GPS is working. Hope this works...

Works like a charm! I struggled for hours trying to get it to work and then ran across this thread. Thanks a bunch!

Can anyone help?
I'm trying to follow the ##GPSCLRX# fix documented here. I flashed to a Fresh ROM to get Sense, and got my MSL code.
However when I dial ##4772579# the dialer just locks up (looks like a previous poster had the same issue).
I got around it by saving the number as a contact and dialing the contact.
The phone rings twice then says:
"The number or code you have dialed is incorrect. Please check the number or code and try again. Message 7, Switch 351."
I tried dialing the same number from a free alternate dial app, same response.
Any ideas? No GPS really sucks
(And yes, I have double- and triple-checked that I'm dialing the right number. And yes, Sprint is my carrier.)
Oh, and using the GPS Tools app: Tools -> "Manage A-GPS state" -> "Reset" didn't change anything.

crazedfred, I actually had the same problem today. I think it might have something to do with Fresh and not the method to fix it. I originally tried using fresh and encountered the same problem you're having.
Instead, I used Sprint Lovers as my Sense-ROM and followed the same instructions and everything worked out ok. If done correctly, you shouldn't have to dial ##4772579#. Once you input the last pound sign you should be prompted to enter the number from MSL Reader.
Just a note: When I did this today I started to have some data connection issues but I'm not entirely sure if they are related. I'll update if I can figure it out.

I've had these issues any time I moved from sense to aosp...I just flash to stock rooted, run ##gpsclrx#, enter msl and actually use the GPS after reboot...

More GPS Help

Hi All,
First time rooting and running custom ROMs so bear with me. Flashed CM 7.1 stable and when I try to go to google maps it cant find my location. Tried to flash the qualcomm 1.1 drivers but no success either. Tried applying those location configuration files for US that another thread suggested but no success either.
Anyone else successfully install the 7.1 stable and fix GPS issues?
Thanks for the help!

Hopefully, you made a nandroid of your stock setup, but you need to be in a Sense ROM, specifically a stock Sense ROM, d/l GPS Status and MSL Reader from the market, and run MSL Reader and get your MSL. Go to maps. Get a lock. Open GPS Status, get a lock.
Go to dialer and dial ##GPSCLRX#. Use the MSL for the password, your phone will reboot.
Open Maps and GPS Data again, and get your locks.
Go to Recovery, flash CM and then op0en maps and GPS Status again. You should have your locks

Yeah, basically flash (or nandroid restore) a backup of a sense ROM. Enter ##GPSCLRX# in the dialer and enter your msl code as the password. You can find your msl code through the market. Also use GPS status. Go to Google maps, get a lock on your location, restore your cm7 nandroid. This is the only thing that worked for me on cm7 but it seemed temporary, which is why I'm on MIUI now.

[Q] [SOLVED] Stuck on 1x

Hey, I'm running cm7 and I've been stuck on 1x for only god knows how long. I know there is 3g around because when I first got the phone it worked. After flashing different roms it seems to not want to connect to 3g anymore at all. Why is this?
Sent from my PC36100 using Tapatalk

call sprint and see if there is an outage

Are you somehow stuck on roam only?
You might need to reset your phone through obtaining your MSL code. I flashed my friend's phone incorrectly in the past before lost his 3G.

I think this may be my problem. I do roam sometimes when I never had before. What should I do in order to fix this?

I am pretty sure there isn't an outage because my friend on sprint has been tooling around on 3g.
I'm able to toggle between the 1x and 4g, but I can't connect to 3g. :-/

Bump.
I'm still having the same issue. Can anybody guide me through getting back to 3G? Would be much appreciated.

If I just switched to the stock kernel and then back to the savaged zen one I'm using now, could this fix my error? Just a thought.

I had this exact sh_t happen to me after a flight from Portland to Boston. What I had to do was flash Sense, wipe, then re-flash CM7 (I think it was Deck's ROM).
See if that helps

Eh.. I mighta been usin' Tiamat (this was like 4 mos ago).

This really works!
I had the same exact problem and this worked for me. I found it on goodandevo.net
After following these directions I upgraded to the latest prl and maintain 3g.
'Turn off your GPS. Dial ##3282#, and select Edit. Enter your MSL, then go to Data Profile. Push the menu button, then tap on Restore. Push OK to reboot. Allow the phone to go through hands-free activation, but WATCH YOUR PHONE CAREFULLY AND PRESS CANCEL WHEN IT BEGINS TO UPDATE PRL.'
Found this in the comments here: http://www.goodandevo.net/2011/09/stuck-at-1xrtt-on-your-htc-evo-3d-heres-how-to-get-3g-back.html
Obviously, first you will have to flash a ROM that has working EPST, after restoring 3g, it should hold thru all following flashes.

I have this problem occur on CM7 randomly as well. I just turn off mobile data for about 5 mins then turn it back on and it seems to fix the problem. Least till the next time.

I've followed your instructions and I read up on that website. I've dragged the two files on to my SDcard and placed the one it told me to in system/app. Rebooted my phone and tried to type in ##3282# and nothing happens. It just dials the number. There isn't an option for me to press edit and type in a MSL code. I press menu and there isn't even an option similar to that. I read up that it's probably due to me using a third party dialer. I am using cm7, so is there a way for me to just show the stock dialer for a second to do this and then go back to the dialer that is set for cm7?

I think the simpliest thing to do would be to flash a stock rom and make your changes and then flash back to your prefered rom. Thats what I did. Flash the stock rom, use EPST and then flash back to CM7. You should have working 3g.

Thanks man! I have obtained 3g and it held through the flash of cm7. For all others who have this problem, just do as his said. The rom I used to flash to properly obtain the correct PRL is located here. So glad I have my 3g back, that 1x speed **** was pissing me off.

[Q] GPS Issue (possible msl issue)

No GPS in both sense and cm7. GPS doesnt lock in both gmaps and gpstest.
Running the latest radio (.722) and cm7 nightly 125.
Tried this fix but no luck.
I got MSL Reader and got a MSL= 000000 (doesn't seem right?)
So i wiped everything...and flashed TSM Gingerbliss 0.2
Dialed ##GPSCLRX# but nothing happens, I don't get anything where i can enter the acquired MSL.
Doing a *228 option 2 got as far as SPL unlocked, then crashed and rebooted phone.
How do i fix this?
Is the MSL supposed to be 000000?
I don't know what else i can try. Any help is appreciated. Thanks!

GPS PROBLEM NO SATELLITE what so ever

hey guys
I recently purchased a used galaxy nexus and as soon as i got it i rooted it and headed to xda to see whats fresh.
After flashing and all that i tried to use GPS but sadly there was no satellite present so there could be no lock or anything
So I flashed another rom and still the same
So I went to stock image 4.2.2 still no satellite was found by my phone
I have look alot of places some say just turn off and turn on the location but that doesnt help either
Can you guys please help me
Right now I am running Rootool box the stable version with fancy kernal.
When i turn on gps... in the status bar it says searching for gps forever.... and the gps icon keeps on blinking.
Thank you

Have you changes Radio baseband?
If not then change it and maybe then GPS works!

GPS and radios have nothing to do with each other.
Does everything else work ok, like phone and data? Is the phone activated and have a good sim? Are you using the gps outside with a clear view of the sky? Have you waited up to 20 minutes for satellite acquisition?
If you answer yes to all the above, try downloading gps status app and use that to download new agps data. See if that works. If not, sounds like you may have a hardware issue.

if this is a hard ware problem should i talk to samsung and ask them to fix it?

Your last hope would be to restore a factory image again and see if that helps. Otherwise, Samsung would be your best bet

should i go to 4.0 build the earliest or 4.2.2?

i had similar problem (no gps) when i tried to force OTA ( i think 4.1.1?) deleting the GOOGLE SERVICES FRAMEWORK
i GOT the ota
but after it started i never catched a gps signal
tried to reset but nothing
i had to manually reinstall from fastboot ( but i was on stock at that time.... dunno if using a modded recovery is SAME thing or it leaves some file behind)
hope it works....
