CM10 Inconsistency & No GPS Lock - Sprint HTC EVO 4G LTE

I rooted my phone and installed the latest CM10 Rom from this XDA thread -- http://forum.xda-developers.com/showthread.php?t=1851912
However, although everything else seems to work just fine, such as Bluetooth, camera, etc., my GPS does not lock.
I've tried searching the forms here but I can't find a definite answer on how to get my GPS to lock.
When I used to have the the HTC EVO 4G, I had to do some ###GPS... stuff in a Sense ROM and then use that to get the GPS to lock when I installed CM7 but I found a few people who tried that and it didn't work.
Also, when I first tried installing the CM10 Rom, I got stuck with the CM10 boot animation so I followed the following instructions and finally got it to work:
Extract the boot.img from the CM9 ROM zip, and flash it through fastboot ("fastboot flash boot boot.img"), and then flash the ROM through recovery (or you can do that in the reverse order, and it should still work).​
I think knowing that may also help.
Anyways, bottom line is, how can I get my GPS to lock in CM10.
I have TWRP installed.

That's not the newest build. Get the newest nightly here: http://get.cm/?device=jewel
Try flashing that and see if it helps your GPS issue.
And if you have HBOOT 1.15 or newer and have to flash the kernel (boot.img) separately in fastboot, make sure it's the one that comes in the new CM10 ROM zip you download from the above link.

Alternatively you can download GPS Tools from the market, it will erase location data cache and reset GPS, pretty nifty tool

I don't know if it will help or not, but some folks have been having luck with this process:
Do a clean install of CM10, wipe system, cache, dalvik, and do a factory reset, or flash the super wipe script that is available(do a search)
reboot phone after install see if GPS locks.
if not, reboot into recovery, and do a nandroid backup of your phone.
wipe phone again and do a clean install of a Sense ROM.
Boot into Sense Rom and get a GPS lock
immediately boot into recovery
this step is optional, but you can do a nandroid of your sense Rom at this point in case you need to go back.
Restore your CM10 nandroid and try to get a GPS lock.
Hopefully Profit!

Thanks for all the suggestions.
I tried all the suggestions but the one that temporarily worked for me was where you flashed a Sense ROM, got a GPS lock, went into Boot and flashed CM10. Unfortunately, this only works while you don't restarted your phone. It was working for me on CM10 but then I tested to see if GPS will lock after a restart and it didnt.
I'm just going to use FreshEVO until an official CM10 build is out and whenever this issue is addressed on a more official level.
Thanks again for all the help!

Official CM10 builds have been out for over a week. Hopefully you followed my suggestion and downloaded one from the link I provided. The one you said you used is an earlier unofficial build.
Hope everything works out for you.

Yup, I downloaded the lasted CM10 ROM and then followed the other two suggestions but the GPS locked during one session after going through a Sense ROM. But, like I said, once I restarted my phone, I lost the locking. I'll just wait until something more solid comes out.
Thanks again for all the help!

Chiming in that GPS still doesn't work in latest cm10.
Really frustrating, cm10 is still far from a daily driver. Any other GPS fixes to try before I go back to MeanRom?

thats odd everything seems to work for me on the latest cm10 for the most part except there is no camera app. Does anyone know where i can get it from

Its suggested to use decks builds and not the official ones. Decks Irc builds will always have the latest fixes

I tried the latest nightly available in the cm10 thread and GPS still doesn't work.
Are the IRC builds even newer than the nightlies? Not having GPS is a dealbreaker for me and I'm unfortunately back on MeanRom until CM10 has working GPS.

Have you tried the clrgps trick? I don't remember the exact code but its floating around the forums, flash back to sense use this to clear and reset the GPA and then open maps to get a location fix, then flash back. Alternatively you can try downloading GPS Tools from the market to clear and reset gps

I tried downloading GPS Tools from the Play store and reset the GPS data and got a fix under MeanRom, then flashed back to CM10 and no GPS at all.
GPS locks nearly instantly under MeanRom, but under CM10 I let it sit out on my car dash for a 30 minute ride and it didn't lock on at all.

Here is the fix that worked for me. Flash to a Sense ROM, download GPS tools. Clear GPS data and then download GPS data. Make a Titanium backup of GPS Tools.
Flash back to your CM10 ROM, restore GPS tools through Titanium.

Never thought of that....clever

In location settings of cm10, you have to them on the internal GPS source. After flash it is set to external GPS source (Bluetooth device, etc.) After I switched this option, and did the sense trick, my GPS locks in seconds.

Where can I find this "GPS Tools" on the market? Whenever I search for that, I just get a bunch of GPS test crap. Is it not called GPS Tools? Also, can you explain the backup process using TB in more detail?

Basically the same thing as GPS Tools, I wonder what happened to GPS Tools, it was really simple to use
