My wife's M835 automatically updated to 3020 a few weeks ago and has been getting 3g ever since. Neither of us have the 3022 yet, but since we already get 3g most places in Jacksonville, I haven't had the temptation to upgrade just yet.

Wait, by applying this the m835 gets 3g on the metro network?

yes, but ONLY IF you have 3g coverage in your area. Metro has been implementing this in select areas and has slowly grown. Some cities have capped speeds, so the 3g isn't all that much better than the 1x we are all used to.

You can look at this thread to see where it is currently, but recently there are reports of 3g in parts of Miami and Atlanta-ish area.

And to edit my previous post, I check the wife's M835 this evening and it looks like it updated automatically to 3022. My Optimus M is still at 3020.

Strange, Does anyone have a PRL file for 3022, I managed to update mine's manually to 3020, but still no 3G around me (Philadelphia, PA)

Link for 3022 can be found in this thread in the Optimus M section.

Prl 3022

Prl 3022

Thanks for that, installed it using CDMA Workshop and still no 3G (Philadelphia, PA)

Anyone know of a way to flash the .prl file from linux?

I don't have access to a windows computer...

Again, if towers are not around, then the newest PRL won't mean squat.

If it is around, you'll have to give it several minutes.

not sure. but you could always set up xp in a virtual machine like virtualbox

 

[CyberTails]

You got a point there, I guess Philly doesn't have the towers yet

Hi guys, I'm new here and a 1st time Android user, I've tried to read and learn as much as I can and so far I've been able to root my M835 with Gingerbreak, installed ROM manager, loaded the Ascend recovery image and installed CM7 with no issues. I've downloaded the PRL file and I also have CDMA workshop 2.7 but don't know how to get it to recognize my handset in Windows 7. I read somehwre that there's supposed to be some COM device detected and that's what you use to connect with CDMA workshop but not having luck with that. As a side note I think I can also load the PRL with another program called LGNPST, but I don't know how to install it, let alone configure it so that I can install the PRL to the phone. Any help would be appreciated.

 

[Vyrus69]

Use QPST, to me its easier and a stronger program to use.

Here's the info on how to use:

@Virus69,

thanks for the reply. I'll definitely check out that link.

Hey Guys just an FYI, if you're trying to flash your M835 with the new PRL, the computer will not recognize a port for your phone if you just plug it in and put it in debugging mode.

A lot of people have been having problems getting a Huawei phone to appear on a port, so you have to do this first, before plugging in your phone and installing the drivers on the computer

I updated my first post on the thread with a guide on how to do it.

 

[CyberTails]

Nice work, I figured that out already a while back, you also need to get the attached driver for the ports to properly work

 

[Apocalypz]

@CyberTails,

thank u for the driver, I was having trouble having my phone detected as a port in Win7 and scratching my head wondering what I did wrong

 

[KillerTiger26]

Does it need root? Just out of curiosity.

Yes you do, because you need to access the data folder fully to get the build.prop file for the editing

When I try to do this: On Phone Dial this code *#*#2846579#*#*
That doesn't work on my M835. Is it because of this that I can't get the drivers that Cybertails provided, to work with the detected devices in Win7 ?? I tried this also with WinXP and it won't take the drivers. I configured the phone for Debug mode and unmounted the SD card unmounted before connecting to the USB.

I attached a screenshot of what I see in my device manager for visualization.

Try this and see if it works: Downloads - Huawei Device Co., Ltd..

Did you dial *#*#2846579#*#*, go to ProjectMenu > Background Setting > Usb Ports Settings and set it to Manufacture Mode? That should make the ports appear

Idk if it's just my phone or maybe cause I'm running CM7 that that code doesn't work on my dialpad ? I'm going to revert back to stock rom to try it out.

It might be, I'm running Stock at the moment due to WiFi Issues with CM7
