I flashed to the stock rom before I read this thread.

The telus radio on my phone is a 1.07 version, and I can only see a 1.04 telus radio to get back to for when I return this phone to Telus.

I guess part of my question is...if this is about quickgps how can it be affecting me after I go back to the telus stock rom without quickgps?

update your radio is the final solution!!!

PERHAPS....

I decided to go ahead and flash my radio...so I flashed the 1.07.06 US Cellular which was the closest to the radio on the phone (1.07.01) and still had the issue....so flashed 1.12.34 sprint radio and it did fix the issue so far.....lets hope so!

Given that the issue is seen even with a stock rom without the quickgps or quickgps file, does this mean the quickgps problem must actually screw up part of the radio settings or code?

But then why did flashing 1.07.06 to my phone not fix the issue...and I think there was someone else in this thread that tried 2 or three radios and it didn't fix the issue....

Ok guys I saw somebody in the Diamond section saying he never flashed his phone but still experiencing problems like us...

is it just me but when I let the phone do an auto update of the time for some reason the phone always puts me on the different time zone... +1 (from my time) actually... -4 instead of my -5 (can anybody check this ?)
I don't know if anybody took my suggestion seriously but the DST time could have something to do with this ? maybe the CDMA clock itself is just spoofing time for a week b4 the old DST time kicks in (which is this sunday) this would mean the CDMA Time would be an hour before the quickgps "time". ( GPS positioning has a lot to do with the relation of a signal sent on a certain time clock... It has to be accurate all the time) I didn't have this phone exactly a year ago so I can't tell if there was an issue in 2008 .

I understand flashing the radio will fix my problem, but I normally flash stuff when I know it can go back to the exact original state and for Bell I can't do that...

I know that some Sprint rom actually do touch the radio somehow maybe this is why some people have success going back to stock rom...again for Bell Mo this is not the case...

Anyone in Arizona want to chime in? Since they don't do DST maybe the cell towers there are giving the "correct" time to QGPS and not causing it to crash.

I'm thinking if nothing else we have to wait 2 more days to see if it comes back to normal.

You are right that getting a GPS fix is all about having the correct time between the device and the satellites..

I did have the time +1 hr problems with some rom's I have tried but not with the ones that I had the GPS problems with. Strange that mine at least sometimes got an accurate fix before it crashed.

Hope this goes away on Sunday.....

I am happy to report that I disabled Quick GPS updates and loaded the provided bin file above and it SEEMS to be working. I've checked google and bing with equal results (success!). I have also checked Garmin XT and that seems to pull a signal quite well (and I'm in the middle of a building ).

Huge thanks for that Bin file. It will be interesting to see if this all goes away on Sunday with the DST change.

Nice of HTC to be of no help on this issue by the way. I do enjoy speaking to CS in our own country, but sending my phone in for replacement and/or flashing the ROM was not the answer to this problem.

Me too, I always get an almost instant accurate fix(within 80 meters) but this is just for 2.5 sec.. then crash, com4 becomes unresponsive and no satellite found until I soft reset... very frustrating....

Thank you ! My last file was from early September so I guess a bit too old... unfortunately still no success for me.

are these problems unheard of on a GSM point of view ?... is this an isolated CDMA situation ?

I tried putting to test my DST theory and tried all kinds of time zone spoofing and combination of time.... again no succes ....

I agree we're still trying to pinpoint the big WHY ?

anybody tried to contact their service provider about this issue ?... I personally did and got the standard automatic answer (hard reset, if nothing go to a store for bla bla bla....)Tried to reach a second level tech and they've never heard of this (for bell anyways)

I'm very glad it worked for you... is this a new phone ?or you've had this phone for a little while ? (maybe newer radios react better with this workaround)

I did this as well with Stock and Nrg rom even leaving the phone off all the time... not even a glimpse of hope.... nothing...

this is very frustrating as I need this GPS badly for tomorrow... I guess i'll have to wait for sunday morning 2 am.... for a big maybe

How many BELL's Diamond here?

I am in the same situation traveling in MD, LA and now in Seattle. I am sorry, but can someone help me learn how to flash the radio rom and which one ? I have a Sprint TP original stock ROM. Mine locks, resets, and i cannot update through Quick GPS. No problem for a year. Does updating to the new Sprint Rom help? Thanks.
