WCDMA shown as 4G ? no 3G ?

Hello,

I've just bought a Xperia Z3 and somethiing is bothering me, I have 4 options in the "Settings -> More -> Mobile Network -> Preferred network type" :

- WCDMA only
- GSM only
- WCDMA (preferred/GSM)
- LTE (preferred)/WCDMA/GSM

When I activate GSM only, I get the "2G" symbol on top in the notification bar, but if I choose any other option I get the "4G" symbol. But what about 3G ? Isn't WCMDA only suppose to show "3G" symbol and not "4G" ?

PS : Just want to let you know that I don't even have a 4G compatible SIM yet, just 3G for now.

Thank you in advance.

only 3g (wcdma) not working on my n9005

i have a n9005 and now i cant use wcdma after cache f2fs

this is what happend

1 - i have flashed ''lean kernel LP version'' on my mobile to format cache partition to f2fs format using twrp.
2 - i successfully formatted cache to f2fs format and rebooted mobile but it went to boot loop.
3 - so i rebooted to recovery and done a factory reset and my mobile booted.
4 - all things went well and used mobile at least two hours and i got this new problem (my wcdma/3g network is not working).
5 - i formatted cache to ext4 and checked but mobile not connecting to wcdma while everything working on gsm .
5 - if i use wcdma only mode mobile displays signals but it says emergency calls only (but i got full 3g signals on my other mobile at same place).
6 - i have re flashed mobile with official kitkat and lp roms using Odin, restored my imei using a backup, rebuilt-ed nv data using a octoplus box, even i tried several kernels too but nothing helped me :eek:
7 - and also I sent it to Samsung repair center too, but even they cant fix it without a new motheboard :laugh:
8. searched searched every ware on net for an answer but I'm the only one out there having this problem
9. my next step is copy a working nv data backup to my mobile from wcdma working n9005 mobile (but no one helps me cos nv data includes imei too) :(

SO please Guys help me to fix my mobile. i love my n3 and I really need to fix it.

tell me your suggestions, I'm waiting cheers :good:

Stuck in TWRP after trying to run a WCDMA test from the engineer's menu

So, I entered the engineer's menu on my LG G3 (T-Mobile: D851) by dialing 3845#*851# on my numpad, and I tried to run a WCDMA test. After doing so, my phone shut off and I was launched into TWRP (v2.7.1.0). I tried to restore my phone with an old backup, but it did not work. I'm not sure why. I've also tried factory resetting it. I simply rooted my phone when I bought it to apply some performance tweaks like saving battery by hibernating apps with Greenify, so I'm pretty ignorant when it comes to solving problems like this. What should I do?

Thanks for your help :)
