Nexus Root Toolkit zip flasher

Can I use the utility in Nexus Root Toolkit 1.7.2 to flash this to my phone?

I have a stock 4.3, which was unlocked and rooted with NRT, but I did not install a custom recovery..

EDIT: worked. Jacksonville, FL. In NRT options I switched the recovery to CW and enabled ROM/AIO.zip configuration suggestions. Not sure if everything is necessary, but it wiped my phone. At the end, the phone went blank and took a good couple minutes to reboot. NRT did not report any kind of success.

Thanks. I read and re-read it and something isn't clicking. :-O I wouldn't be this hesitant if I was at home with my computer, and the fact that things are going well with 4.2.2 and seeing how there are still kinks to be worked out with 4.3.....

Thanks!
[Nexus 4 General] cb474:
I just tried this out for the first time. Wow, this is great and it was ridiculously easy. Thanks bpear96.

One question. Before enabling LTE, I always kept my phone locked to 3G (WCDMA). I get poor reception at home, my phone would keep switching between 3G and Edge, and badness ensued all around. I found my reception and calls worked much better just keeping the phone locked to 3G.

With LTE enabled however, it looks like the only options (in *#*#4636#*#*) are LTE only or LTE/GSM auto. Does "LTE only" really mean only LTE will work or will it revert to WCDMA if there's no LTE reception? Alternatively, does LTE/GSM mean that the phone will potentially move between LTE, WCDMA, and GSM, depending on the signal? Ideally, I'd like to lock the phone to just LTE and WCDMA.

Thanks for any explanation.
[Nexus 4 General] Berrydroidcafe:
There is no WCDMA radio in or for the Nexus 4. It will either be LTE or GSM.
[Nexus 4 General] efrant:
Unfortunately LTE only is just that. There is no setting that I'm aware of that disables only the 2G radio. :( But yes, LTE/GSM auto uses all three radios.

??

Of course there is. There is a 2G radio (GSM/EDGE), a 3G radio (WCDMA), and an LTE radio.
[Nexus 4 General] efrant:
I think you probably should look up the difference between a CDMA radio (i.e., what Verizon and Sprint use) and a WCDMA radio (i.e., what GSM providers use).

*UPDATED* [ZIP] All in One LTE Enabler, Flash ONE zip, and have BAND 4 LTE on any ROM

I re-read it, and in the thread CDMA had come up, and unfortunately I got it twisted in my head. My bad! :banghead:
[Nexus 4 General] arlenwoot:
No worries. It's a common mistake, a lot of people get confused about it.
[Nexus 4 General] cb474:
Thanks. I guess given that LTE works over AWS on T-Mobile and I was getting my most consistent reception with HSDPA/WCDMA over AWS, perhaps I'm okay just locking it to LTE. I suppose, in either case, with my 3G only setting (before I enabled LTE) or with LTE only, I'm locking it to AWS and that's probably what matters most for my reception. (I don't know that I was ever really getting the refarmed 1900 Mhz HSDPA on T-Mobile--although it was hard to tell, since nothing in the phone settings is able to tell you what frequency you're on).

And I guess voice calls go over HSDPA anyway, since T-Mobile doesn't have VoLTE yet. Although in the network manager app, it says my net link is LTE and my phone link is GSM, so does that mean voice is on GSM with LTE, not on HSDPA? (Which would not be consistent with what T-Mobile says.) And can the phone simultaneously connect to both? It's all a little confusing.
[Nexus 4 General] efrant:
Since there's no VoLTE, if you switch the setting to LTE only, you will not be able to use voice. Voice is over either GSM or HSPA.

And no, unfortunately you can't force the N4 to use AWS or 1900. The option to select individual bands is disabled.

Edit: fixed typo.
[Nexus 4 General] bruce7373:
So with LTE/GSM enabled, is the transition from 4G to 3G/Edge an "efficient" one? Meaning will my phone hold on to a 4G connection however faint the signal before it switches over, even if the 3G/Edge is stronger, or will it automatically use whichever is better at a given location?
[Nexus 4 General] cyburke:
is most everyone who has enabled LTE on their device happy to have done so? or is the effect on battery life not worth the switch?

i get decent enough HSPA here in Los Angeles, but my curiosity wants to experience the LTE... :-o
[Nexus 4 General] GriffenD:
I live in LA too and have had great coverage and pretty good battery life using LTE. The difference is pretty marginal and I still get good usage out of it.
[Nexus 4 General] efrant:
Good question. If you come across any info on this, please share.

All I know is that, for example, "WCDMA preferred" and "GSM auto" modes both flip between 2G and 3G. The difference arises in which signal each holds onto in various circumstances.

The following is pure speculation on my part: I believe WCDMA preferred will prefer a weaker 3G signal over a stronger 2G signal, while GSM auto will prefer the strongest signal.
[Nexus 4 General] asoong:
So far, for me, the switch has been great! In SF, CA, 4G where I work is faster than my home broadband. At home, I can barely maintain an EDGE connection but I'm always on WiFi when I'm home so no biggie. As for battery life, I would say its been the same or even slightly better than before.

Then again, I'm a former sprint user so just about anything is better than what I had before :p
[Nexus 4 General] arlenwoot:
I'm very much happy I enabled it, and the battery life seems to be about the same.

[Nexus 4 General] cb474:
Yes, I discovered this last night playing around with the settings, no voice in LTE only mode. So LTE/GSM is the only pratical choice.

I was not asking if there was a way to lock the N4 to AWS, I was just thinking through the fact that since LTE is only over AWS anyway, setting my phone to LTE only would effectively be a means of locking the phone to AWS. But obviously given the lack of VoLTE, it's not an option.

*

When I was experimenting with this last night, I notice that as soon as I place a call the phone switched to HSDPA. It did it very efficiently and I had not even realized this is what it was doing in calls (basically it happens instantaneously as soon as you place a call). It has to drop LTE to place calls (i.e. cannot remain connected to LTE for data and place the call over HSDPA simultaneously). The switch back to LTE after a call was a little slower (took a couple, even maybe five seconds).

For what it's worth, I'm finding LTE to work well in my home, where I get poor reception and, before enabling LTE, my phone was constantly switching between Edge and HSDPA--making it better to just lock it to WCDMA only. But with LTE enabled the phone seems to prefer to hold onto a weak LTE signal and is not constantly switching like before (in a way that caused dropped calls, etc.).

Curiously, I also noticed in the Network Signal Info app that when connected to a weak signal in HSDPA, like -108 dBm, the graph in the app colors this level signal red (as in poor signal), but in LTE it holds onto -111 dBM fine and Network Singal Info colors this as green (as in good signal). So maybe there's some reason why LTE works better with a weak signal?

It could just be in my head (and/or the new .84 based radio), but it seems to me like enabling LTE has improved my radio hopping, drop out, issues in weak signal areas.

*

I get fast HSDPA also and was thinking I don't really care. But as you can see in my post above, LTE seems to have improved my probems with weak signal areas (maybe T-Mobile is devoting more tower resources to it?). And in strong areas, I'm getting 10 Mbps down and up, which is about twice my HSDPA, also a better ping. Enough that websites load noticeably faster. And in weak signal areas, like my home, I'm getting 2 Mbps down and strangely enough 5 Mbps up, which is much better than I was getting with HSDPA. So all in all it seems like an unqualified improvement. Also not noticing any battery issues so far, though it's only been a day and a half.
[Nexus 4 General] bruce7373:
I'm seeing exactly the same, so it's not just in your head. LTE is not strong in my apartment in L.A., but it's consistent. It constantly switches between H/Edge (often no signal at all) when on HSDPA. In stronger signal areas, H+ and LTE are pretty much the same, but I stick with LTE. I hadn't realized it switches during calls. I've been experiencing no dropped calls whatsoever.
[Nexus 4 General] cb474:
Good to know I wasn't just imagining it. Sounds very similar to my experience with HSDPA/Edge, before I enabled LTE, the constant switching back and forth, as I said above, and the frequent no signal at all. Hope the much better experience with LTE holds up!

PA 3.99 + Hybrid 0.27/84

Aloha and Thank You sir (I mashed the Thanks button)! You saved me a lot of angst and anguish. I just wished I searched more thoroughly and found this thread first before I went and manually did most of the changes only to find out that it didn't fix the voice problem. Unlike the last time, I did this on Paranoid 3.99 based on Android 4.3 instead of the Google Stock (and Rooted) 4.22. LTE worked but not voice, much to my dismay as I use the phone a lot.

After I flashed the 0.27 version, I had both LTE and Voice! Didn't have to do anything else, thank gods! Sometime next week, I'll try the 0.33 version and see whether I get any better performance in anything. As is, I'm just happy to have working LTE AND Audio! Hope my LTE WiFi Tether also works tho as I use that a LOT too. I'll let ye know later on that point. And no I admit that I haven't bothered reading the whole thread to see if WiFi Tether has/hasn't been an issue or not. I'll do that later when I have more time available (I start work in 8 minutes). :)

Mahalo Nui Loa Kakou!

-Lan

EDIT: Appears that all is well. ...except for WiFi Tethering still is down. I've read around and appears that it's in my case a ROM issue. I'm running PA 3.99 and appears that there's something missing in therein to enable WFT. I'm kinda disappointed as I just installed PA and it's otherwise a serviceable rom. I'm seriously considering switching to a different rom that has either WiFi Tethering fixed or is relatively easily fixed ...and STAY fixed. Oh well, time to do some researching.

On Morrislee's thread, I learned that I have to flash the LTE enabler first, then the modem. When I install a new ROM, I only have to flash the LTE enabler again, and I do not have to flash the modem again.

If you flash a new rom I believe you will, but if you use a rom like CyanogenMod that has a built in updater, then no you wont have to as this includes two backup scripts.

There is NO missing amplifier for LTE Band 4 on the Nexus 4...
[Nexus 4 General] nycebo:
:eek:

Sorry for the mixup. Searched the web a bit and quite a lot of potentially misleading information then. So, am I now correct in stating that the LTE amplifier and duplex are (and always have been) present in the Nexus 4 but simply that they were disabled in (i.e.- missing from) the radio profile?

With that hopefully cleared up, does battery performance suffer any more than LTE on other phones (for example, my SGN which falls precipitously when using and hunting LTE)? I am going to install it anyway but just wanted to crowd source some data is all.

Thanks again.

UPDATE: Have also been reading this thread.
[Nexus 4 General] efrant:
All necessary hardware components for LTE Band 4 are on the N4 (but it is missing amplifiers for other bands). Google/LG disabled LTE in radio firmware newer than 0.33. Using radio firmware 0.33 or older, or, using one of [MENTION=2880885]morrislee[/MENTION] 's hybrid radios will allow the LTE radio to be enabled.

I haven't really noticed much difference in battery life with/without LTE. Based on my usage, battery life is always poor :)

Dumb questions

Based on experiences with my OG EVO, I learned that I could get a better WIFI signal if I turned off GPS. I don't have any WIFI issues with my N4 but would turning off GPS produce a better LTE signal?

My LTE speeds with GPS on is usually 18-26d/19u. Today, it was 17d/18u. Immediately turning GPS off and restarting speed test, it connected to a far off host (today it was in MO and I'm in CA) and I consistently averaged 30d/19u. It might be that my local speed test hosts are just slower than other hosts but I was wondering if any one else got better results with GPS turned off.

BTW, I rebooted my stock but rooted N4 running 4.3 with the .33/.84 radio and my settings survived.

TIA!

That's kind of incorrect. If he only flashes this and wants to go back to stock , he'd need to flash the stock ROM again. But, flashing only this file does nothing, you need to flash the LTE modem too, so in that case to go back to stock you need to flash both the stock ROM and stock radio.
