Dear all, I have M8sd China telecom version. Flashed M8st Rom to try and working but no 4g. So tried pressing *#*#4636#*#* and selected USA Band. No signal detected. Factory reset and restored M8sd backup didn't help. Still without any signal. Please help!
I Have the same problem
I have enabled other band selection (other than USA and 800mhz) from the unlocking band in the Sony thread. Chosen Euro band and is working normally now.

Hi all. I am completely stuck. I've been trying to unlock wcdma band to work on China Unicom for 2 days. Flashed alot of stuff without success. Nightly cm12, phandroid 5, cm 11s, and ALOT of different modems that were suggested.
Now, no matter which rom I flash, there is no signal at all. Wifi only works on Official CM 11s .
Please Help.
Edit: In the *#*#4636#*#* When I try to change to original band I cannot. Its stuck on WCDMA. Also In mobile networks, change to 2G from 3G it stucks on 3G. Can I change somewhere to unstuck this?
Hello everyone,
One month ago my device had a problem of rebooting again and again and again. . . , I give my mobile phone to service center, they said you need to change motherboard to solve rebooting problem.
But I didn't change mother board, my rebooting problem solved when I pressed power button hardly.
In service center they disassembled my phone to checkup. after then when I got my mobile phone back my new problem started.
My problem is with cellular network, my build number is MMB29K my radio is radio-hammerhead-m8974a-2.0.50.2.28 my device bootloader is unlocked. my bootloader is bootloader-hammerhead-hhz12k
My device is unable to find cellular network when I set preferred network type to 2G, my device can only find network on LTE and 3G.
I tried this different radios too radio-hammerhead-m8974a-1.0.25.0.23.img, radio-hammerhead-m8974a-2.0.50.2.26.img, radio-hammerhead-m8974a-2.0.50.2.27.img But nothing works,
This is a hardware problem?
Anyone have idea how to fix it?
Please help!!!

Does your carrier support 2g? In Canada, there is only 1 carrier that has 2g.

Hmm, possible loose connections inside the phone?
I have the same problem, im from indonesia and im using D821, after upgrade to marshmallow, my phone only have 2g, no 3g/4g. i have solved the problem.
- first i downgrade my n5 to 4.4.4
- flash modem using recovery NEXUS5_KRT16M_RADIO.zip
- Reboot your phone
- flash again modem using recovery NEXUS5_KTU84M_RADIO.zip
- reboot your phone
- go to setting, more - mobile network - APN
- reset all APN on the list than create new apn of you mobile carrier.
- and the problem solved.
nb: bootloader must unlocked
( i dont know why should flashing the modem twice, i have try only flashed NEXUS5_KTU84M_RADIO.zip from the stock of 4.4.4 but the problem still on my phone)
sorry for my bad english.

Hello
I successfully upgraded my L04 to 6.0 b810, but now my phone cannot use 3g network (it has very weak or no signal), so it works mainly in 2g/Edge.
Are there any possible methods (eg. flasing proper modem, etc., im not really a pro in these) to revover my "signal loss" and get 3g signal strenght back?
Thanks for the anwers.

problem still exists
Downgraded my b810 mm indian to b521 lolli EU, but the problem still exists.
5-15 mins after reboot, H+ network flyes away, and the phone only works in 2G/Edge mode.
If i try to select only 3G mode in settings, it just cannot find any service provider.
please help me :crying:
