Maybe it was me sending LG an angry email letting them know that I've switched the a Nokia Lumia 920 because they support their customers better, or maybe it was Microsoft.

But, whatever it was. I downloaded Zune and plugged in my (fully reset (erased)) windows 7 LG Quantum (bought on first day of WinPho 7 release) and voila it started updating!!

Didn't expect that! I'll carry it around along side my 920 tomorrow to see how it works!

Wow I'm pretty amazed and glad!! I have the 900 but I already updated to 7.8 weeks back. I hope this means that a lot more phones got the update than expected!

[Catholic Tech Geek]

Who is your carrier? I am on AT&T here in the US, but I haven't had much luck trying to get the update.

[Razdek]

I'm with Bell and the update worked for mine

[rossart12]

I've spent hours trying to get mine to update (on AT&T) with no luck, I managed to get it to 8107 with the cab trick but after that I hit a wall.

But if anyone has theirs dev-unlocked, or has an extra Quantum lying around, this might do it. http://forum.xda-developers.com/show....php?t=1381162

[Raylz]

i wonder i think US carriers are last to get updates? =/

[The_Traveler]

For that phone it was bell, but for the Lumia I switched to rogers/at&t

I got my LG Quantum on AT&T working using SevenEighter: Questions about Unlocked LG Quantum C900

[inteller]

the cabs are not on the update servers for ATT.

[Sotal]

EDIT: Just completed the update using an ATT branded Quantum through editing the Registry

Thankfully, LG provided all the tools needed to change the registry, so while the update may not exist on the AT&T server, it does on Bell CA.

(Even though its relatively safe and easy, it is still at your own risk)
1. Start with these instructions
2. From Step 7 onward, in the input data field, enter in "BEL-CA" (without quotes) and press set
3. You can exit out of the app now by pressing the start button (MFG will now appear in your Apps list, but I usually just uninstall it after I'm done)
4. Restart your phone and set it to Airplane Mode
5. Check for Updates on Zune (I had to use the cable trick a total of 5 times for each update from 7720)
6. You should now have 7.8

Some notes:
-BEL-CA for the carrier as they are the only other operator besides ATT who have device support for an LG Quantum
-Your mobile service should not be disrupted as the device targeting info, from my understanding, is just how Zune recognizes your device
-You can change your MobileOperator back afterward if you feel safer
-Post your results!

Now running 7.8 on an AT&T Quantum after SevenEighter ended up doing most of the work...and loving the updated UI, plus the Tango features I never got.

There is hope LG Quantum owners! Just completed the update on an ATT branded Quantum without having to flash a new ROM or use sever-eighter.

Thankfully, LG provided nearly all the tools needed to change the registry, so while the update may not exist on the AT&T server, it does on Bell CA.

that's not an ATT branded quantum, after what you did it is now a Bell branded quantum. There is no non hacked solution for ATT.

[Sotal]

Why sound so negative about it? (Yes there is no non-hacked solution I suppose)

It's a method that does not require a 3rd party download and it still gets an official update through Zune.

I'll make a concession that it might not be what AT&T might provide to get you up to 7.10.8858.136. However, by your own opinion you told me you don't believe that an update for the Sammy Focus will get pushed through from AT&T, so we should expect the same for LG, no?

Much more, I doubt if AT&T does do anything to it, it'll be very insignificant.

Take it as you like, but this phone still only accepts AT&T sim cards and I changed the MobileOperator back to ATT-US after the updates.

I just really wanted the phone to have 7.8 and I didn't want to wait for AT&T to sit on it for years, if they were planning to release at all!

[inteller]

I'm not being negative, I'm being clear. You are not and it will confuse users who search for threads looking to update ATT branded phones. All you are doing is rebranding which is the same as debranding which is NOT an official update from ATT.

[Sotal]

Yes, I updated the post. But realize people are look for solutions with what they have.

I won't digress too much but from what you posted in reply to me before couldn't this be construed as misleading?

i predict ATT won't push the updates for any phone other than the 900. You will have to debrand or reflash to an unbranded rom to get it.

[oldpueblo]

Trip report, I just used Seven-Eighter and it only got me to 8779 for some reason. I kept trying and it just kept doing 8779. So I then switched the brand from ATT-US to BELL-CA as above and Zune finished the job and took me all the way to 7.8. I then branded back to ATT-US. So far looks to be working great.

no because everything in that statement is true, ATT hasn't pushed updates and the only way to get it is to debrand.

Mine is not allowing it to go as far as 7.8 it stopped at 7.10(8107) It says that it is up to date.

[money50021]

I cant get mine to update. Whenever i connect to zune, it says that there aren't any updates available. Has the update even officially come out? (I'm on at&t)

[HerronScott]

No it's not out officially on AT&T.

I've used SevenEighter to update my Quantum phone to 7.8 (7.10.8858.136) with success. It went through a series of updates which I believe did it about 3 times before finally settling on 7.8. Also I had changed the MobileOperator to BEL-CA from ATT-US which I assumed also contributed to making it work. So those who are wanting to make the jump can do it at their own risk anyways.

Doing it through Zune gave me issues which I was getting a 000FFFF error code and the solution to fix that was to wipe my phone which I wasn't willing to do. Hence when I found SevenEighter, it allowed me not to wipe my phone and keep all my data intact. So far I haven't had any issues yet.

[discohaze]

So to go back from Bell to ATT, I just go back into MFG and putt ATT-US right?

[oldpueblo]

Correct.

[scdkad]

Dumb question-I still have my 2 year Quantum but no sim card. Do you need a sim card in to do this update?
