The problem is that when the network settings are auto GSM / WCDMA / LTE doesn't work an Internet connection and when are set to auto GSM / WCDMA internet connection returns. The problem occurred on the 20D and 20B. At the CM13 everything works fine. I've tried to replace the list of APN but didn't help.

Just rooted my Desire using instructions from Modaco, but have the following issue :
I have no data connection. No matter what I try it always tells me 'unable to connect, you need a network connection in order to..... etc. Wifi is off at present (not one around at work) and all the settings are to Vodafone as they should be. Can make/receive calls without issue. It's a fully unlocked phone so no idea why it's suddenly not able to connect data wise. This is the case whether I try to setup Exchange, browse the web or open Facebook etc.
Any ideas please anyone? I've checked all settings, rebooted etc but to no avail.
Someone, somewhere said that in some cases (don't remember which) APNs presets are missing after rooting. Check your APN setting.
1. Make sure your APN settings are 100 correct.
2. Go to Menu--Settings-->Wireless and networks-->Mobile Networks-->Network Mode--Switch to GPRS and then Back to Auto
Worked for me.

Are you using a Branded or UnBranded Desire??
see this thread for more info

But at a guess you might need a GoldCard and then Flash it with a new ROM/Radio settings
Phone: m919
Rom: CM11 Nightlies 2/4/14
Carrier: AT&T
Modem: Mk2 baseband w/Mdl non-hlos
I have searched and tried methods of trying to get LTE working by *#*#4636#*#* and selecting LTE/GSM auto (PRL) but the setting never sticks and it reverts back to GSM auto (PRL). I have also tried under settings/mobile networks/preferred network type to LTE/GSM/WCDMA and that always reverts to GSM/WCDMA auto. I also have tried different APN settings "ATT Phone" should be right although I have tried ATT LTE pta and ATT wap.cingular.
When I select the LTE options I do receive an LTE signal until I make a phone call or lose signal/reboot. It then switches to Hspa+ and never automatically back to LTE.
I first thought it was a hardware issue but I tried a GPE rom and LTE worked great! Too bad GPE isn't CM
I'm bummin... any ideas?
LTE issues fixed with CM11 jfltetmo nightly 2/7/14! :victory:

Hello
After reboot phone setup wcdma/gsm network priority. There is also problem with changing to lte/wcdma/gms , you cannot click it directly, need first click like gsm and then lte to make it active.
Using official lolipop , IL customization
Anyone noticed 4G/LTE problem on Lolipop ?

I'm having the same problems, but I finally get LTE working
Same for me. But I don't have LTE yet. So didn't bother too much.
maybe you can try this:
FIX 4G PROBLEMS
edit build.prop
- look for 'telephony.lteOnCdmaDevice=0' and change it to 'telephony.lteOnCdmaDevice=1'
look for 'ro.semc.version.fs=GLOBAL-HSPA' and change it to 'ro.semc.version.fs=GLOBAL-LTE'
reboot your phone
type *#*#4636#*#*
Select phone informations (first menu)
turn off radio
in network prefered I've selected TD-SCDMA, LTE, CDMA, EvDO GSM/WCDMA
turn on radio again
exit
type *#*#4636#*#* again and look in network prefered, it will be on LTE/GSM auto (PRL) and 4G should be there
LTE/4G issue after hard reset
Hi to all,
and thank you for the tips doenen.
I have the same issue since i hard-reset the phone.
Just to be clear, if we want to edit the build.prop file, we have to be rooted ?

Hi, I did all the steps except the ro.semc one, because there is no such setting in my build.prop. However I still wasn't able to get 4g working, it just keeps switching back to the old settings.. Any ideas? Running cm12.1 android 5.1.1
Re issue with LTE/4G
Hello,
i got my phone back from SONY's technical services, cause i had a bunch of issue (i sent it twice in a month).
For now, the battery drain isseu seems to be fixed, but i do not have 4G/LTE.
I already encounter this issue, and after the service menu manipulation, everything got back in order.
I tried to do the same manipulations, but i can't turn off radio. It's like it was locked.
Any ideas ?
Thanks for helping.
Regards

Worked for me,cheers.
The Nougat to Oreo OTA update would never install so I did a full wipe and manually installed OCXS27.1 via flashall. since then, I lose all signal/data every 2 minutes or so. If I go into Phone info (*#*#4636#*#*), I notice the Mobile Radio Power toggle will switch off/on intermittently.
when I try resetting all network settings, the connection becomes consistent but the phone doesnt recognize I have mobile data (shows full bars and 4G LTE icon).
I have tried several different basebands and their corresponding OTAs but the issue persists, an issue that was not present on Nougat.
- M8998TMO_20207.117.02.41.01R
- M8998TMO_20207.117.02.41.02R
- M8998TMO_20207.117.02.41.05R
- M8998TMO_20207.117.02.41.06R
I've even tried a different sim card.
any ideas?
When at Phone info, you can change Preferred Network Type to Global (PRL) or LTE/UMTS auto (PRL) if you are outside of US. My ATT (of course carrier unlocked) is now running on LTE/UMTS auto (PRL) and everything is fine.
