i'm curious if anyone has been able to add code that would allow toggling within the quick settings? i have a network mode tile in my quick settings that allows me to toggle between 2g only / 2g+3g / 3g only... wondering what it would take to get the network mode to toggle LTE.

i'm not a coder so i have no clue, would appreciate any help if anyone has tried.

So... anybody have an idea why I can't connect to LTE on Bell? I've read a lot but no one seems to have been successful on Bell.

Am I wrong here?

I have an LTE SIM, I have an LTE enabled account, I have entered the *#*#4636#*#* code and changed to LTE/GSM, LTE only, LTE/GSM/CDMA, but nothing works.

I've also created a new APN even though that shouldn't be necessary for Bell.

I'm stumped!

[Nexus 4 General] XanSama:
Confirmed that this method doesn't work on Stock ROM. To get the menu to show up in "Mobile networks" you need to set the Cdma line to 1; however even then the GSM/LTE options aren't present, and none of the options you pick from that menu seem to stick regardless.

Just so you guys have an alternative to setting LTE on boot.

I've tried it on AOKP and it works, can someone try it on stock and see? What this'll permit is to set your fast network (LTE) on boot, on screen on, screen off, when wifi is off, etc.

Try it out! Worked for me.
[Nexus 4 General] machostallion:
Do you have access to LTE towers to test? I thought KC and Vegas are the first to go live soon. Seems like you would still need to put in the new LTE APN to get that app to function. I've put in the new apn and I still connect to hspa+ getting the usual speeds here in downtown DC. Don't know when we are slated to get any LTE
[Nexus 4 General] karendar:
yeah, you have to have an LTE APN configured to connect to it. And yes, I've tested it. Switches from LTE to HSPA+ no problems whenever I leave a zone and back. Really works well.

hi,

heard that the Nexus4 hardware actually supports more than band 4 AWS, but is disabled in the baseband profile (software)?!

Is there already some patched baseband firmware available or will there likely be at some point?
[Nexus 4 General] karendar:
I doubt you'll find a patched baseband unless someone feels very adventurous... But in the meantime, you can always try the baseband dumps that were supplied in the modem thread in the general section. I've flashed .27 and ever since, I seem to be getting a much stronger signal on LTE... .27 was pulled from a debug firmware, so it might have some things enabled that others don't.

based on what i read on anandtech nexus 4 has hardware support for bands 1 and 2... so would it be possible to copy the software stack from the optimus G to the n4? sorry if it seems im the nth person to ask this.
[Nexus 4 General] zivan56:
Give it a try. I can whip you up a new radio that may or may not brick your phone if you want to take the chance. I am fairly confident it wont though, as there is a separate boot image which contains standard Qualcomm SoC boot stuff.

err well, the thing is... im not a developer... :S
[Nexus 4 General] estallings15:

[Nexus 4 General] zivan56:
Which Optimus G has Band 1 LTE?

I have uploaded a test firmware with Bell Optimus G (E973) radio (AWS and 700 MHz (17) LTE).

REMOVED

If someone is brave enough to flash it. Extract the .img file and run

fastboot flash radio <filename>.img

You should be able to flash the original radio back with the same above, as I haven't modified the boot.img. Assuming boot.img is capable of providing fastboot services. Which I can't tell for sure.

If this works, users in the US on AT&T on 700 MHz should have LTE. Likewise, if the hardware isn't there, people in Canada should still be able to see Bell/Telus/Rogers LTE.
[Nexus 4 General] ran495:
strangely enough, i can't seem to find the information, but its most probably the asian version of the optimus G. if that one is for band 4 and 17, i dont think i will be able to test it.
[Nexus 4 General] zivan56:
Well, the idea is the same. If it doesn't brick your phone and the 2G/3G still works, then we can use Optimus G radio files interchangeably without issue.
[Nexus 4 General] cmstlist:
The hardware diagrams have clearly shown there are no radio components in the N4 compatible with any 700 MHz LTE band. Nice try though.

[Nexus 4 General] DJ_Jedi:
In Italy we don't have the LTE for a long time (just since november) so i'm not confident, yet, with the bands.

By now our operators are using 1800Mhz for the LTE service, there's any chance in getting the N4 connecting to 4G with a proper radio? Or it's better to wait the Optimus G to pop out in Europe to grab the radio and give it a try?

The only thing getting me away from buying the N4 is the lacking if LTE but if just flashing the radio i will buy it in no time.
[Nexus 4 General] cmstlist:
No. The Nexus 4 has LTE on exactly one band, and it's not your band.
[Nexus 4 General] DJ_Jedi:
Oh, so it's an hw problem, flashing the radio wont fix anything? Btw what band is the one in the N4 and what band is the 1800Mhz, i Googled it but cant really find a good answer.
[Nexus 4 General] cmstlist:
The Nexus 4 has LTE Band IV (AWS). Your carrier uses LTE Band III (DCS).
[Nexus 4 General] DJ_Jedi:
Thank you very much.

Btw according to iFixIt the N4 has a Qualcomm WTR1605L Seven-Band 4G LTE chip and a Qualcomm MDM9215M 4G GSM/UMTS/LTE modem, so the hardware should be there, just the software lacks of the right things.

I hope we have a brave enough user who decide to flash an Optimus G radio to try.
[Nexus 4 General] lafrad:
http://www.anandtech.com/show/6474/nexus-4-includes-support-for-lte-on-band-4-aws

These guys tested it.

No actual Hardware present for the 1800mhz bands (or at least,that's their story)

HOWEVER, it does appear that those 3 power amplifiers they listed cover *4* bands of UMTS/LTE spectrum.

AWS (Band 4, which is what TMo and Canada support) shares the "upload" (power amplifier) frequencies with Band 3 (1800 mhz), and the "download" (receiver) frequencies with Band 1 (2100 mhz).

In theory, it should be possible to enable LTE support for all 4 of those bands... the amplifiers *and* modem hardware support it. you just need the software to proper enable it.

---------- Post added at 10:46 AM ---------- Previous post was at 10:19 AM ----------

THinking on that,

Google could make a LOT of friends if they did enable LTE for all bands that the hardware is present for. its not a perfect solution (missing the 700mhz bands prevents some AT&T folk from hopping on), but it would get *even more* people onto the "pure" android experience....

This is what i got from anandtech's article:

"I tore down the Nexus 4 to ascertain whether PAs were present that could work with LTE, and saw indeed that at least bands 4, 2, and 1 did have Avago power amplifiers (A5704, A5702, and ACPM–7251) which noted support for LTE. The remaining piece of the puzzle was software stack, both in Android and inside the version of the AMSS (Advanced Mobile Subscriber Software) running onboard MDM9215M."

Doesn't this mean that the hardware for bands 1 and 2 are there and are just missing the software?
[Nexus 4 General] kaiser_tytnii:
Yes, band 2 and 4 for lte, but band one for umts only, refer to my prior post in last page

Hey guys, I'm with koodo and have enabled LTE and it shows 4g with 2 to 3 bars but when I try to run a speed test it says "network error". I definitely have data as I can access the internet with nice loading speeds. Do you think I may have to set up a telus APN to get speed test to work?
[Nexus 4 General] mrbkkt1:
Try clearing data from speed test first.

I've tried that and I've tried all settings except lte only in phone menu. I don't have 4g signal at my home but I'll try the lte only and the telus APN next time..kinda strange as telus and koodo are the same network AFAIK.

No idea but I'm having the same issues too. I've checked my apn settings and tried all the LTE options but none of them works. Just get the empty triangle representing no service. If this was an LTE phone I'd RMA but since it's not official there's little I can complain about.

[Nexus 4 General] DJ_Jedi:
I was Googling if any brave have flashed the Optimus G radio and i found this: http://xdaforums.com/showthread.php?t=2099784

So, i think the mod will flash the N4 radio on the Optimus G since it disable the LTE and to enable it you have to flash the ATT's radio back and this should tell us we can do the reverse with no problem.

Any volunteer? :)
[Nexus 4 General] zivan56:
Well I decided to give my own custom radio a try. Bottom line is it didn't work, at least properly. WiFi couldn't connect (can scan for networks) and cannot find any cellular network.

I'm sure the wifi issue can be solved by not copying over the WCNSS image files. However, the radio is a bit hard to say. My best guess is that the LG firmware uses custom AT commands init the modem. That's why it works when you take an Optimus G and flash the radio and system from a Nexus 4. Someone would have to be brave enough to flash the LG firmware on their N4 and give it a try.

At least we've confirmed that as long as you don't flash the "boot" partition, the N4 will still boot.

One caveat, it seems "fastboot flash radio" does not like overwriting radios. Perhaps its some sort of anti-downgrade mechanism, but I had to use a CWM flashable zip to get the N4 radio back. The CWM image does a raw write to the radio partition. Using fastboot to flash will say it did flash and the version will change in the bootloader. However, it doesn't seem like it actually does.

Also, I found it interesting that the "baseband version" numbers in both the bootloader and OS are simply the name of the FAT16 radio partition. So it has nothing to do with the actual firmware version on the phone. They could simply release it again with the same label and "trick" people into upgrading with a later firmware update.

Anyways, I don't really have much time to fiddle with this, but it should be somewhat safe to mess with the radio partition. At worst the modem won't boot and you will have to flash the stock radio back again. Since the modem is independent of the SoC, and the SoC boots from the "boot" image, it will at least be able to get into the bootloader. That being said hopefully CWM will boot at least if the modem fails to.
[Nexus 4 General] Simmo3D:
If I can use fast boot to flash I will test it out. Just need someone to post a link to the Optimus G radio for me plz

"Nexus 4 hardware and software were not designed to be compatible with LTE, and future LTE capability on today's Nexus 4 will not be possible because of hardware and software incompatibilities. We've heard reports that some users have reconfigured their Nexus 4 to enable LTE under rare circumstances, but it is uncertified and unsupported."

It suck big time. Especially since you buy something knowing LTE can be turned on and then the company that made a device that's so open to everyone, now makes an update specifically fuking up the LTE.

This is exactly what Apple would do, nice going Google

They should have done this right away in 4.2.1

I am just saying it's not fare at all, upseting as this phone is nothing but just something to hold me up till next year. Disappointing, at least with Apple or Sams. you know what you are getting, they control the soft, never thought such OPEN Google will do this.
