Root T Mobile, AT&T, & MetroPCS LTE fix.

Ahh.... So when I do a complete wipe in TWRP (system, data, caches), that's considered a factory reset. With my PC mentality, I always considered it going back to a factory stock state, which would involve a reformat and loss of data.

It seems like going for LTE would definitely slow down my crack flashing, which might be a good thing, lol. Another consideration - when at home I'm lucky to get a couple of bars and EDGE2. When I was on .33 and the LTE apn, I got zero connection. Not that I need mobile data at home since I'm on Wi-Fi, but does that impact receiving/making phone calls? Sorry for the noobish questions, but this is new territory for me.

Don't wipe system, because that clears your os and your phone won't boot without flashing a rom. A factory rest it just data, cache, and dalvik.

If you have no connection, then the phone is only good for dialing 911. Calls and sms will not get through until signal is regained. So it sounds like it might be a good idea to remedy that if you plan to use the phone portion of your N4.

In twrp they have (since version 2.5 I think) under wipe it says factory reset, wipes data,cache,and dalvik. Not internal storage.
They just call that factory reset.

However for the lte stick you need to use the rom factory reset. that will open twrp and factory wipe, again not including internal storage.
In menu backup and reset, factory reset.

Now in the phone info menu you will put it to LTE/GSM that will give you LTE preferred data but it will switch if needed. Also it will allow phone calls to come in and go out.
The phone can not work over the lte radio so it has to be able to switch to make and receive phone calls.

Right. Because I only do factory resets when I'm clean flashing a ROM, system always gets included. Thanks for that distinction.

True. I wasn't clear on whether making and receiving calls (ruling out SMS) is dependent on the mobile data network or not. I think I'll play with it some more and see if 4G is really ask that necessary for my needs before making it permanent. At least now I have more insight to it. Ta.

Edit: looks like it might be necessary, lol. Just now sitting in my living room (where I'd been getting 1-2 Mbs down/0.5 up) with HSPA, I clocked 11+ down/4 up with LTE. And this with no bars showing at all.

Later: I tried twice behind the fix suggested on hippowise.com to work and I kept getting H+. I'm pretty certain I didn't skip anything. Keeping the .33 radio with fingers crossed for a better solution.

So here's where I'm at guys. I did the setup and, since I barely get EDGE in my apartment, I took a drive to a spot where I got 15Mb with H+ yesterday. I got 4G, but no LTE, at around 13Mb. Meh. But...the upload was sweet, about 3-4 times faster.

Anyway, since I can't get the network mode to stick over a reboot, I've gone back to H/H+. But I'm wondering if there's any advantage to staying on .33 (or .27 even) or just go back to .48. My whole objective here is to make my reception at home better. Or is the only thing that's going to fix that is more towers?

Radios .33 and below bork camera autofocus FYI

bruce73 · Jul 20, 2013

FWIW, I just tried both the camera and Camera Zoom FX and neither one worked. FX froze the UI and the stock camera wouldn't even open (this was on .33). Went back to .48 and both apps work.

I think the camel's back just broke, lol.

All IN One Flash to change the radio, edit build prop and fix audio.
Even includes a method to easily reverse all the changes.
Tested and works flawlessly on my N4 4.2.2

I can't tell you how thrilled I was to finally find an AIO that will Flash the radio of your choice, edit the build prop and fix the dreaded no audio issue, AND LTE sticks after a ROM update without having to always dial *#*#4636#*#*
Excited enough to post this news three times.

Flashed this 5 days ago on my N4-PA 3.65 nightly and Franco kernel.
Not a lick of trouble, other than breaking continuous focus.
[ZIP] All in One LTE Enabler, Flash ONE zip, and have BAND 4 LTE on any ROM

HAPPY TIMES in DFW!!

That is true, but if you use apps that scan barcodes you're usually out of luck as those apps rely on continuous autofocus (most such apps have no touch to focus functionality)

bruce73 · Jul 21, 2013

This is maddening, lol. I'm so close, but no cigar. I tried this latest method after the manual editing didn't work, as well as another flash found on xda which supposedly works with .48 (couldn't get LTE to stick in the Network Mode menu).

This method got me the closest, though. While it worked great after flashing (I still had to edit the APN to fast.t-mobile.com), my N4 (AOKP M2) cannot find the G4/LTE signal after a regular reboot. All the LTE settings stick; phone status even shows its connected to LTE, but it isn't. Meanwhile, H+ is just happy as a clam, patiently waiting for me to switch back to it, then connecting without hesitation. It taunts me.

I flashed the version with .33; I see no point to flashing .27, unless someone can confirm otherwise. I'm starting to wonder if it's a regional thing (I'm in L.A.).

I didn't have problems with mine sticking and I didn't factory reset anything.

Followed steps, rebooted and everything showed up just fine. Rebooted again to make sure it sticks and all is well.

My n4 is the non nipple version. OG.

Aokp with franco kernel.

I use barcode scanner, probably one of the biggest used scanners I have not had any trouble getting it to scan.

OK, I have to know what that last statement means, lol.

After much trial and error I discovered what the problem was. LTE settings so persist through a reboot, but when toggling between 4G and H+, it's necessary to change the APN immediately before the phone finds and connects to a signal. Not really for H+, as it can access fast.t-mobile.com as well as epc.tmobile (although at a throttled download speed), but 4G can't access epc.tmobile.com (at least in my part of LA).

My question now is: can I create a new APN profile for LTE rather than manually edit the APN in the one profile that exists by default, even though the new one wouldn't be referenced in the APN config file?

jhawkkw · Jul 22, 2013

Yeah, you can add as many apns as you want, I have like 4 due to carrier hopping lol.

When you open up the APN setting hit menu and add new APN.

I know how to create a new one; I was just wondering if it would work without a reference in the config file. Anyway, I went ahead and made a new one and switching to it works fine.
And... I still need to know what the "non nipple version" is.

lol ok.

The Nipple version has two little bumps on the back bottom of the phone, which is speculated to do 2 things,

First keep the back glass off the surface so it can not slide around as easy.
and second to allow sound from the speaker to be heard easier.

The non-nippled version, like mine just does not have those two bumps on the back.

If its not in a case it can slide off a table on its own.

No nipples also keeps the glass off a cold surface.
Some suspect that the back glass set on a cold countertop caused it to crack.

You got me curious, I dont use barcode scanner often, So I just tried it on several random items it worked on everything I tried it on.

Including the QR codes on the computer screen.

For some background I am using older PA rom, 3.15 with pa kernel and .33 modem with lte tweaks.

What APN should I add other than fast.t-mobile.com?

Does that help with dropping data signal? That is the only issue I have had since I enabled LTE

jhawkkw · Jul 23, 2013

The fast.t-mobile one disables hspa+42 to my knowledge, so having a second one for epic.tmobile would be helpful because that's the one for hspa+42.

The fast.t-mobile one has a cap, it does not disable hspa + just limits the speed while on hspa on lte the cap is not there.

So if your in an area with little or no usble lte put the epic apn in to get the best speed available.
If your dropping data signal do you mean lte picks up then drops, no or slight signal bars?
or is it on hspa? does it constantly switch between the 2?
