Yes I did try that too
Once set GSM only. phone will lost signal

I have had good reception with the TX, though have sometimes needed to force gsm only in bad areas but no problems like you are describing.

[Q] Data not working, because of root?

Hey guys,
Did anyone of you have your LTE not working because of root?
Seems like mine isn't working at all, I have a C5303 on .257 FW rooted.
Now, I don't know if it is the SIM's problem or something to do with APNs, but in theory, will rooting my phone with the above specs ruin my mobile network? Did anyone face this before?
Thanks!

I had issue where the data connection was not being saved Head to manually setup apn.
Now all working and downloading and making calls.

[Q] C6603 not having 4g option (UK)

Hi,
Hoping someone can shed some light on this odd problem I have. I'm on EE in the UK which is at moment our only 4g provider. I smashed my old S3 LTE screen so my girlfriend (Who is on 02) upgraded early to an xperia z, which we were assured is 4g compatible. We had to unlock the phone to work on my network of course.
However, after unlocking I don't have the option to change to 4G in the network menu.
I've checked the following:
The phone is the C6603 model, which I double checked supported the bands and frequencies used by EE
I receive 4g in my area (Used to with old phone)
I checked with 02 that the phone was 4G compatible
However I'm guessing it's been turned off in the software that 03 loaded to customize the phone. I can't for the life of me find any info on the internet on how this is done or reversed, and I'm a little hesitant to flash the ROM as I would be murdered should I brick the thing.
Any ideas? Anything appreciated.

I flashed the Spanish 4.2.2 ftf file onto my UK 3 Z.
That gives me the option to use LTE networks. You might have to do something similar to get yours to pick up a LTE signal.
Did you say the phone was from O2?
Its also a piece of piss to flash ftf files. You don't even have to root or unlock the bootloader.

Yeah, phone was got from 02. I suspected that there's something loaded with the bloatware... Hm, so I guess I need to try flashing and risking the wrath of the girlfriend should it go up the swanny..

Dial *#*#4636#*#* and in phone information there is an option to change to lte,try it.

Now this is odd, I had the option when I went in there... But it flicks straight back to WCMDA Preferred. I also just rooted it.. so I'm confused now.

So better to do what warface suggest.

Phone disconnects data when switching to LTE

So I unlocked my bootloader on my ZL, Im asking here because this forum is much more active then the ZL forum, then relocked it and transferred TA back again, and Im not sure if its me, or the phone, but ever since it seems as if when switching from HSPA to LTE data disconnects for a few seconds, then LTE will come on. Does anyone elses do this?
Thanks

My ZR actually goes completely off network for a second when i toggle LTE on and off. Not all the time but sometimes. The other times, it does disconnect data.

Yes, this is what mine does when connecting to LTE, I lose all bars and get a red X for a few seconds, then it comes back to LTE. So I guess this is normal?

That's not firmware issue, that's resul of having aluminum/steal frame.
It has been reported that Z1 could lose signal in low signal area because it has that kind of frame/body...
