LTE radio issue - Xperia SP Q&A, Help & Troubleshooting

Hello,
I bought an Xperia SP from bulgaria and the model is C5303 who supports LTE bands. The issue is that there is no such an option on settings to select LTE/WDCMA/GSM band. Only GSM and WCDMA. In the secret menu (*#*#4636#*#*) i cant select the LTE/GSM/WCDMA option, or any other option except GSM or WCDMA. When i press LTE option, it returns automatically, to WCDMA Preferred.
Any ideas?

Use flashtools to flash a stock ROM that is for c5303

Thank you. I wait to be approved in order to use flashtool

Have you tried just to reset the phone to factory settings (wipe)? If that doesn't help perhaps you really should flash it with stock rom of your carrier/GSM provider, or at least try kernel only? Could you be so kind and post a screenshot from the normal settings screen, the part where you should have 3 options but you got only 2 (not the via code menu)?

Did you try Settings -> More Settings -> Mobile networks -> Network mode, set it 4G only or auto connect.
Another workaround maybe there's problem with your apn's? For example I had it set to MMS then ahd EDGE available only.
Second warkaround is secret menu, type it in dialer *#0011#.
how to set up MMS then ahd EDGE available only?
and i typed ?*#0011# and its showing

I have exactly same problem with silver.. Have you fixed it? I have tried to fix problem some, but nothing looks like gonna fix it...
I have tried everything that was written on the forum..
When I check *#0011# it shows that only GSM900 is available...
Anybody?
Have you tried changing it to WCDMA. I was having that problem with the 3g service not going above a few kbs, I changed it from gsm to WCDMA nd its back to full speed 3mbs.

Where did you buy it?. Did you see if the modem frequency of the carrier it's available in your phone?, I got the same problem and it's possible that my phone doesn't have the hardware ready for the carrier in my country. I still looking for an answer.

[Q] No LTE option ( C5303 )

Hey guys I am new to xda forums, I recently bought the xperia SP ( c5303 model ) and I have this strange problem.
When I go to network mode I only get these 3 options WCDMA only GSM only or WCDMA/GSM auto and no LTE or whatever option...
First I thought it was a provider's problem or something but I checked that my 4G connection is enabled from my provider for my connection..
So I went to a store that has all the devices for exhibition and checked another xperia SP and found out that on that one (which had no SIM or internet connection on) that If I go to the settings there I could find all 4 options ( WCDMA , GSM , WCDMA/GSM and LTE/...) . So propably its something wrong with my phone or I dont know..
I Contacted Sony support on my country they told me to factory reset the phone and if that dosnt solve it repair the software or whatever with PC companion ...
I did both and had no luck on finding a solution, so I thought to ask you guys ...Help if you guys have any clue on that
P.S Just read a related thread http://forum.xda-developers.com/showthread.php?t=2331317&page=2 and did this
To check:
Go to the dialer and enter;
*#*#4636#*#*
Click on Phone Information
Scroll down to Set preferred network type and check if LTE is an option
Found it but still cant select it so my question is .. Is something wrong with my device or it has to do with the provider etc ?
Thanks in advance!
did you try to flash stock firmware? or just repaired it using pc companion?

Nop ( and basicly I have no clue what's that flash stock .. I just repaied it using pc companion ) ..
I think it has to do with the provider or something judging from what I read to similar posts
Just If anyone could confirm it would be good
Try to read about flashing using flashtool.it will be a great help to you. Also maybe it can resolve your problem.

Help Needed for Enabling LTE/4G on my HTC One

I own a HTC One M7_U and recently I've installed cynogenmod following the steps mentioned in one of the Thread of xdadevelopers.
After upgrading to Cynogenmod I am able to select the Preferred network to LTE (recommended) but not able to get 4G network on my phone. By searching few of the threads I found that using *#*#4636#*#* I can select the preferred network from there. But when I selected LTE only using this method, it automatically got changed to some other option (say WCDMA or LTE/WCDMA). I am only able to get 3G/H/H+ network.
Kindly tell me whether LTE/4G can be enable on my phone ? If yes, kindly tell me help me out with this problem.

The M7_U doesn't have an LTE radio, the faster you'll get is HSPA+

ZR does not get coverage in WCDMA mode.

I'm looking for a solution to ultra frustrating problem I encountered after performing OTA lollipop upgrade from kitkat. My network coverage gone after lollipop upgrade, I can't make calls or send messages. While I played with settings i found that with in Preferred network type there are three options as below.
WCDMA Only
GSM only
WCDMA (preferred)/GSM {Default option}
It was set to 3rd option. When I changed to GSM only option my calls and sms started to work flawlessly but as you all aware Internet was on 2G(Edge). To get HSPA working as far as I know I have to use WCDMA in xperia phones (Not to be confused with CDMA). When ever I switch to WCDMA my coverage goes off.. I can't make calls. So i end up using the phone in GSM only mode and made a thread in official xperia site as below. I also tried repairing using PC companion and resetting the phone no avail.
http://talk.sonymobile.com/t5/Xperia-Z-ZL-ZR/xperia-zr-c5502-does-not-support-WCDMA-after-lollipop/td-p/1001920
As you can see one person with the ranking of moderator acknoledged the issue and suggested me to revert it back to Kit kat until the fix has been made. I tried flashing using flashtool still problem exist. Even in old kit kat firmware which i was using it for long time with out any issues. I think some thing has happend to my mobile after lollipop upgrade.
Yesterday I unlocked the boot loader and flashed Cynogenmod 11 as well.. Again same problem. WCDMA does not work thus no 3G. Now I'm using Sony official lollipop firmware by flashing via flashtool.. I ended up using my phone in GSM only mode (Edge).
Any suggestions? Ideas?
I would try downloading stock LP ftf file with XperiFirm, then using Flashtool and try flashing only baseband. Not sure if it would work if you install a KK baseband, i would stick only to LP files in the meantime.
There is also another option to force select the bands, just dial *#*#4636#*#*, go to "Phone Information", and on the preferred Network type, choose "WCDMA Preferred". Wait 5-10 minutes, it might take a while for the carrier to recapture phone signal.
If that doesn't work, you might want to check if somehow the bands were locked with the LP install. There is an excellent guide on how to unlock bands, i tried with my SO-04E (japanese C5503) and i was able to unlock some of them, as not all carriers on my country were recognizng HSPA, and were recognizing only EDGE.
