WCDMA / HSDPA / 3G not working

Daalgo · Feb 7, 2014

Dear community,

i'm writing on behalf of a friend who is owner of a rooted HTC One M7.

He has an issue with not being able to get more than an EDGE connection. WCDMA / HSDPA / 3G is not available at any time.
We tried to change radios/basebands, upgraded to latest 4.4 KitKat Viper, but no success.

The issue is not provider/sim card related, it works fine in other smartphones.

Any ideas ?

HAve you checked the preferred network type settings? Dial *#*#4636#*#* then select ''phone info'' and make sure preferred network type is set to ''GSM/WCDMA/LTE auto''.

thats not the issue, its in auto mode. Selecting only WCDMA results in no mobile connection + not being able to call out and receive calls. Like the phone is "dead".

Ever heard of problems like this ?

If the phone has unpaid bills, declared lost/stolen then the IMEI can be black listed and you won't be able to make/receive call and sms.

Second hand phone?

NO, nothing of all them. Phone was brand new. It is just when phone set to WDCMA mode. No internet connection + in/out calling not available.

When setting to automode, which turns to EDGE on normal GSM mode, everything fine. No issues.

Potentially corrupted IMEI/EFS/NV data information. Something similiar afflicted S3's a lot, but never heard of it happening on HTC One devices. How did it happen? Same also happened on HTC One S, if you ran the WWE RUU on North american RUUs.

Perhaps a side-effect of wrong MID? What is it?

If the phone is still under warranty, you might want to go in store to get a replacement one. Then if you tampered with the phone maybe you should try to go back to 100% stock and see if this issue persist. Don't know more about this sry.

Its the correct. M7_UL

Have you tried to S-off to be able to flash the latest firmware/radio of the 4.19?

Also, might be worthwhile to get another SIM from the carrier, even though the current one works in another device. The One is a picky but sexy lady!

Just a thought, but can you also check your APN settings, and possibly adjust/add one to them. the APNs the carrier send out automatically might now be the correct ones (that's in my case for example), and i've seen other users also have to change APNs manually to get better speeds and/or LTE.

oh and i just noticed the radio you're using is from US Dev Edition, try a WWE one from here: http://xdaforums.com/showthread.php?t=2419699

the latest seems to be working quite fine.

Thank you all for the help. But we still didn't solve the issue.

What we have done now:

- We s-offed the device.
- We changed the CID to HTC___102
- We flashed an EU radio.

- We ran the latest EU ruu 2.18, after it OTA to 2.19.

At no point we had 3G/H network. Is there any possibility that the 3G modem is broken ? I googled quite a few hours but could nowhere find a similar problem like this.

2.18 then 2.19? shouldn't it be 2.24 for EU.

Still sounds like an APN issue to me.

APN settings are correct. No 3G/WCDMA with other sim cards as well. If we put put his daily use sim card in an Iphone it works flawless. (i think i mentioned that already^^)

I mean we can exclude an software problem now after having ran the RUU or ?
