有難うございます.日本人の方ですよね.
どうやってLTEバンドを切り替えますか?自分は402SOを買って,ドコモのRomを焼いて使おうと思いましたが,成功できません.
そこで,AuのRomを焼いて,LTEバンドを切り替えれば良いと思いました.ですが,前代の401SOのようにできません.

LTE/CDMA auto (PRL)
Okay it may not be the service mode. I'm seeing that km connected to lte:14 but my speeds are a out 2mb/s does anyone have any ideas?
Bump. Anyone have an idea of what cloud have slowed my lte so much? Thanks in advance
Alright I think I figured this out and wanted to share in case anyone needs it. I guess something got screwy when I was messing with stuff but I just had to reset the modemml. To do so go to service mode then UE Setting>setting> system> stimulation> MODEM ASSERT (RESET) and that's all I needed to do. Hope this helps someone with very slow lte!

Secret menu

I came across this app last night in the play store. https://play.google.com/store/apps/details?id=org.vndnguyen.shortcutmaster.lite
I was able to access some menu's I haven't seen elsewhere. I have the Sprint G3. Some of this stuff is beyond me and I'm not sure if it's anything helpful.

Add this to your thread mate that's a lot of thing going on in there. There's some screenshots too. I enabled LG Health on my phone which wasn't there when i first got my phone.
Im not really sure but i guess the BandSelection menu is where you can get your LTE only. But make sure you have a backup. I didn't tired this on my phone.

Yes: your phone supports 4G/LTE
1. Do you have an U-SIM
2. Do you have 4G/LTE activated for your subscription
3. Do you have 4G/LTE coverage
4. Does your network support 4G/LTE

Meizu Metal 3G and 4G connectivity not working

Hi Everybody,
I have bought Meizu Metal from Aliexpress and received it few days ago. Everything is working smoothly except the 3G and 4G connection. The system version is Flyme OS 5.1.2.0Y, YounOS version 3.1.6. The GSM network is working fine. The specifications of the phone clearly shows that it supports 3G and 4G networks : 4G FDD-LTE:Bands:B3,B1 , 3G WCDMA:900/1900/2100MHz. My local operators supports 2100mhz for 3G and B3 for 4G. The phone detects 3G and 4G connection , but when I try to start browser or any app that requires internet it fails to connect.

Have you set APN values? If you haven't, find out those values with your carrier.
