Have you tried flashing again? At which point do you get the black screen? If it's after the bootloader, a reflash should work. Otherwise, to be fair, I have no idea.

Thanks for the tutorial! I got it working perfect the first time with the USB Tethering.

I would like to try the Flashed ROM variant, for the wifi tether, but I am worried a bit. If I made a backup and something goes wrong, can I restore it to remove the bad effects on the phone? I've done the backup with this tool: http://forum.xda-developers.com/show....php?t=1103011

Data not working after flash to Telstra ROM

---

Hi,

I just flashed a C900B (Bell Canada upgrade channel) to the Telstra C900K ROM. I am on the Telus Canada network in Ottawa, Ontario.

Everything was fine except my data would not work immediately after the flash.

I needed to enter my APN (sp.telus.com) before my data connection would work on the phone... I'm not sure what this means, but anyway, it seems to work fine so long as I have the APN entered. It definitely does does not work without the APN, even though it used to work fine with the Bell C900B ROM.

Anyway, if I find any problems, it looks like I should be able to easily revert to the Bell ROM found here: http://forum.xda-developers.com/showthread.php?t=935605

Looking forward to having wireless tethering... Thanks!

EDIT: After running the LG Network Setup app, I no longer need to have the APN entered to have my data connection work. Seems like that Network Setup tool does do something good! Thanks LG!

"LG Update for Windows Phone" not happening

---

Alright... So I it looks like everything after the flash to C900K is working great except for updates (and therefore the internet sharing).

I've tried it twice, once with the sim card removed for the whole process, and Zune checks for updates after entering a name for the device, but seems to think the device is all up to date (even though it doesn't have the internet sharing update and is still at 7720). When manually checking for updates through Zune I get: "Your phone is up to date. Current phone software version: 7.10 (7720)"

Here's my details:

Model: LG LG-C900k
Carrier: Telstra
Software: Windows Phone 7.5

OS version: 7.10.7720.68
Firmware revision number: 1.0.4.10
Hardware revision number: 1.1.0.0
Radio software version: 1.0.4.10
Radio hardware version: 0.3.5.0
Bootloader version: 1.5.1.0
Chip SOC version: 0.30.2.0

I also tried updating to 7.10.7740.16 through the manual CAB method, but that did not enable internet sharing, though it seemed to apply the update fine otherwise.

Any thoughts? Is there maybe a CAB for the "LG Update for Windows Phone"? Maybe Zune is now blocking updates for this ROM?

Thanks,
Allen

I'll flash my other Quantum with the stock mango ROM for Telstra, then use Wireshark to capture the update CAB for you, which you can then push with the cab sender method. I'm not sure when I'll have the time to do this, however. Stay tuned

Hi Allen,

I had the same experience as your. However, I am able to find the solution for this. All you need is the WIFI Tethering Drivers - 1.0.5.10 (December 2011).

I use CabSender tool to update my LG C900K from 1.0.4.10 to 1.0.5.10
After that, I can see the Internet Sharing option.

Awesome! That's what I was looking for! It worked great and now I have fully functional internet sharing, thanks Keith!

I was looking at this thread, which does not have the internet sharing drivers:

Too bad that the updates aren't being picked up by Zune anymore. Please let me know if anyone figures out how to fix this. It would be better than manually installing all the updates through the CabSender.

Thanks again!
Allen

Hey, just a quick update on my update problem: I plugged the phone in and opened up Zune and suddenly it has the updates for me (I had manually updated to 7.10.7740.16 through the a CAB and Zune just gave me the 7.10.8107.79, 7.10.8112, and 7.10.8773 updates all at once). Yay!

Yuhu. I've managed to get the USB tethering working on my Quantum with a Romanian Orange SIM Card.

Now I have to see if I shall fully flash the Telstra rom. Will I be able to upgrade to 7.8 when it will be released? Or will I be doomed to flash updated roms instead of getting official updates?

Thanks.
