Holly Cow! I can change the WCDMA (4G) Band!
I just changed it to 1900Mhz. This is good for people who are in areas that are overloaded on the Band 4 1700Mhz/21Mhz.
This is also good for checking if an iPhone or any AT&T phone would have 3G/4G in your area. Here is how I did it:
1.) Enter this code in your phone dialer: 3845#*769#
2.) Select "Network Mode"
3.) Remove the check from "Automatic".
4.) Select "WCDMA frequency bands"
5.) Select "WCDMA 1900"
If you want to go back to the original band select "WCDMA AWS" and then check "Automatic" in the previous screen.

According to the hidden menus the T-Mobile P769BK may work on these frequencies:
WCDMA/HSPA/UMTS: 850 900 AWS(1700/2100) 1900 2100
GSM: 850 900 1800 1900

P769BK has 10 point multitouch and maybe more. I ran out of fingers after 10.

To check which band your phone is currently connected to in the service menu do this:
1.) Go to "Modem Settings"
2.) Go to "Engineering Mode"
On the first screen it will show"
RAT:
Band:
If Band is UMTS_FDD there is no signal. Mine shows UMTS_BAND_II which is 1900Mhz.
This band is much faster than band 4 1700/2100Mhz when doing a speed test.

you are really amazing. L9 forum is new and badly needs fearless contributors like you . well done bro.
I just want to ask everyone "DO AT YOUR OWN RISK and only if you know details like kevev know"
Service Menu is not for playing around and not for everyone.:silly:
Tried on my P765 with following and it worked.
3845#*765#
Choose and use wisely. Too many commands are there. Will explore later.

what band do you recommened since i guess i dont get 1900 here? AWS has always been slow here for some reason, but after trying 1900 and then going back it sped up a little bit!

Since you are on T-Mobile, AWS(1700/2100) & 1900 are the only 3G bands available.
The reason why you notice your download speed getting faster after switching back to AWS is because you disconnected and reconnected to the network.
You get priority over every other device that has been connected longer. It is a shortcoming of T-Mobile's network since way back when they started as VoiceStream.
You can do the same thing by going to airplane mode for a few seconds and then disabling airplane mode.

You can, but be careful.
Sent from p765.
You give me one more hope to root my p768f. For now all WCDMA 850 firmware are unrootable and I cannot use orther firmware because I cannot change network back to WCDMA 850. I'll try to root my phone with V10 Vietnam tonight and see if WCDMA 850 work in that firmware. :good:
Try to flash p768 and p760 firmware on my p768f and found that it don't support WCDMA 850. Reverse back to unroot p768f again.

Oh. That's brave thing to flash other variant. Just tell us was everything else working? Was is booting normal? Any strange observations like they find touch issue in P769?
Sent from p765.
Most p768 can be flash on my p768f, If there are any error after flash just factory reset it and it'll work. Only problem with p768 is my 3G network other function seem to work. So I try p760 to see if international variant support my 3G. It don't and gave me many error popup so I think there are incompatible software library with my p768f (don't try factory reset yet). And this is my last attempt to flash other variant, I've to wait for proper root exploit from dev.
Not recommend other user to flash other variant if your rom work fine. You may not hard brick your phone but something may not work.
thanks for this (=
Not work on cyanogenmod 9.

Had this happen for the second time today. During a call, the handset makes a loud buzzing noise and restarts itself. It's not like the buzz when it vibrates, it's actually coming from the phone speaker. Anyone heard of this being an issue?*

You could try re-inserting the sim card. I have had a few random reboots after the sim card had worked itself loose
---------- Post added at 08:26 AM ---------- Previous post was at 07:50 AM ----------
Just realised my issue was probably down to the fact I had installed sim card without the sim card tray.
Did anyone try this yet on the new 4.4.4.
This would be great for people traveling a lot.
Skype already does this

But I will try the new native toggle in two weeks
I tried domestically and it's OK. But for international, I think we might get charged for it.
Please let us know.
Sprint's international Wifi calling is only free for calls to the US, US Virgin Island, and Puerto Rico numbers: http://support.sprint.com/support/a..._calling/173e331f-8423-453e-93cb-4688f6a91f67
Hi guys, sorry if this has been asked before, but is there an EE stock rom floating about?
Short story is: my lg g5 was stolen, my insurance replaced my g5 but it no longer has wifi calling or access to the 800mhz 4GEE network as it no longer has carrier specific firmware on it, therefore I want to flash carrier specific firmware to the phone.
Is this possible?
Cheers!
I downloaded one a few months back, let me see if i can find it quickly online, otherwise I'll upload it when i get home.
