Hi,
while i was messing around with the network setting via *#*#4636#*#* menu, I accidentally selected the USA bands, and it has caused me to not able to make any phone calls or even be connected to the network.
It does not allow me to change back to the default bands I was - international
Understand that this seems to be quite common mistakes across different devices.
But specifically for Desire 816, anyone can help me with this? My device is not rooted (i'd like to keep it taht way) and bought unlock.
Anyone? I'd be super grateful! Panicking like crazy right now...

Hey its simple and worked on mine!
Got to *#*#4636#*#*, then enable Flight mode using the Power menu, or your status bar toggle, then click Select Radio Band and you should see Automatic, now before you select it, disable flight mode. Hope it works, else in order to reset RSD settings, you need to factory reset (unless u root ofc)

Thanks for the reply!
Tried it, but the automatic option did not show up on mine
So how do you factory reset? I did reset through the phone settings already, also tried recovery, none worked...

I flashed CM10.1 on my S3 and had the same problem as others where data was intermittent. It worked for some time and after one nightly, I lost my IMEI. So I got back to stock, used the procedure with QPST and got back my IMEI. I got back to cm10.1 and unsurprisingly, I had a hard time having data. But worst off, I had a hard time having cell connection anymore, not even voice or sms. Tried AOKP without any luck. Tried different modems, not luck either. Now I went back to stock and still doesn't work. There's something that is not resetted between flash of ROM that keeps messing up my connection. I also found out that only one network provider is ever found, one is Rogers Wireless (I'm with Bell), or one is EXT. But never any other provider is ever found. And also in *#*#4636#*#* under phone info I can'T change the radio band like I can on the phone of my girlfriend.
So there it is. I'm stuck. I don't really want to buy another phone. It is a software issue for sure. But how can we solve that? Is there any way to restore the EFS to factory default? Could it be buried there? What is the ERI? Could it be that? My stock ROm says that it can't get the ERI version.
Any help is welcome.
my stock telus ERI is unavailable but i think thats normal... i have no problems
from what i understand imei and apn settings are the things to check into

IMEI and APN are good. IMEI will get me data, but I can't even get a cell connection now. No radio at all.
whats your radio band set to?
if i set mine to anything but automatic it wont find networks like yours..
*#*#4636#*#* dont work on my telus s3.
i use a different method
*#197328460# then
UMTS > Debug Screen > Phone control > Network Control > Band selection >
Automatic...
beware what you change in here as there is no return to default

Neither of the two works. *#*#4636#*#* was working with CM10/10.1 and AOKP. But not with stock. And the one you suggest after is not working either.
But I remember going ot *#*#4636#*#* before flashing stock rom and I wasn't able to selet any band. On my girlfriend's android phone (HTC) I can.
if it were me.. i would try reflashing stock again... after flashing stock do a factory reset thru recovery... seems to help for clean stock setup.
if still no network i would check that band selection is set to automatic.
maybe someone else with more experience would have a better idea.
you mentioned you changed your band selection and now cant change it back.
i dont think flashing stock changes this.
i think that might be your problem.
ifso you first need to fix phone to use *# code... i have no idea why its not working
it works on my stock telus 4.0.4 and 4.1.1
maybe bell blocks from using *#code?

if i were u i would first try your girls sim in your phone and vise versa and if no luck do the qpst instructions to regain LTE not imei .and if u still cant manually find network operator after that i would format both sd cards and odin back to stock rooted and do the imei injection again for the hell of it and the LTE fix ..and stay on stock rooted or 4.1.2 until u get this figured out cause 4.2 builds are gonna have more probs then 4.1...I know u are having cell connect probs and these instructions are for imei and data but it sounds like your out of options....i lost imei once and had to manually inject with qpst and my reception was one bar til i did the LTE fix and it worked awesome..one more thing is my phone will not select a radio band ever unless i manually select my network operator first or i have no sim card in phone..i have also had sim cards crap out for no apparent reason..good luck
edit. my bad i thought your girl also had gs3..maybe the sims are still the same

Thanks for your answer. Really appreciated. I've flashed so much time that I don't see the point of doing it again. I also had, at some point, to inject my IMEI and it worked with QPST.
What I find really strange is that a stock reflash doesn't put everything back to when I bought the phone. Funny thing, after the flash, it knew what my Wi-Fi router password was! So obviously there are some part of the config that is not overwritten. Which I find odd.
I also started playing with the service menu and found a lot of settings for the radio band. No luck yet.

Your WiFi password could have been restored by google just like it puts your contact info back.
If you are doing a Odin to stock that should wipe it clean.

This thing is so strange. There's only one network that my phone can see now, and it is 302720. Bell is 302610. No other network is visible. And since I'm with Bell, then I can't connect to 302720. I'm in for emergency calls only. That's why I thought it may have to do with radio. But it seems Rogers (302720) and Bell use the same bands. A channel maybe? But this should be all automatic! It's a pretty stupid bug let me tell you!
Maybe a SIM card issue? That would be quite a coincidence that it happen exactly when I'm playing with ROMs...

Ah that's a good possibility. I didn't know it was saving passwords as well.
So if it wipes clean, how come this bug stays? There is obviously something that is not wiped and overwritten or else it would work.
How can one tell if someone losses their IMEI number? Unable to make phone calls? No 4g/ lte?

When you go to info about your phone, in status you usually have your IMEI number. It'll show 0 if it's corrupted. Or sometimes it's a generic IMEI dans is used when the real one is unknown. It's 049 something I think.
Without an IMEI number you can do phone call. But you'll never have a data connection.
I recently flashed the V10L software onto my D855 and I've noticed that when I restart my phone two things will happen.
1) Quick memo+ will always appear as the first item in the notification toggles, need to deselect it from the edit menu.
2) the phone network types will automatically deselect the one with LTE auto, it also defaults to the 2nd one from the top everyone I go into that menu and I need to change it.

i am facing neither of these problems.
You backup your data and do a Hard factory reset. That should solve your problem 99% !!
Do it and revert back.

I'll give that a go now, by hard factory reset do you mean going into settings>backup and restore>reset phone. Option?
Edit: I reflashed the firmware which my handset originally had (was the 10J) and the issues I stated above have dissolved, maybe it's something to do with the carrier being Optus Mobile. hmmmm
my phone suddenly start to turning off by itself after few minutes of every startup.
And the phone doesn't recognize the sim cards too. Then I put it to flight mood and the problem solved. If I off the flight mood then again the phone turn off after few minutes.
I factory reset and also flash different roms. But nothing changed.
I can use phone without any issue with the flight mode on.
Anyone have a idea about the cause of this issue?

It's very likely that it might be the baseband or wifi driver, i had the same problem a while ago but i can't remember how i fixed it now. Probably flashing the original baseband. Maybe also by changing sim settings typing *#*#4636#*#* on phone application. Tell me what you see doing that.
One more question, did you mess with Nvram?
Actually I don't know about Nvram. I didn't mess with it intentionally. I don't know if something happened. Is there a way to check it?
Please help me. I don't know what to do exactly. What settings should I change by typing *#*#4636#*#* ? Thank you for trying to help me

No problem
Go into phone information change your current band settings to GSM/CDMA/LTE auto then restart, see if it works if it was already set to this option try changing to another setting. Btw you can't check nvram if you didn't touch it, don't worry

By changing band settings phone keeps turn on without airplane mood. It didn't turn off automatically. But No reception for both sims.

Hi,
I've upgraded my note 4 to MM using the "Bootloader unlock and safe upgrade to MM "post from the general section. Now I'm having the next problems:
1.-I'm using a GSM Sim Card and it works but when I try to change the network mode I only get LTE/CDMA and CDMA, if I select one of those the networks, it stops working, and to go back I have to do a Network Settings Reset.
2.-I cant use MMI codes from my operator, I think that this might be due to the first problem.
What can I do to fix this?

Is this the only solution? install another ROM?
Same problem on 5.1.1. Non VZ SIM, two phones (both VZ Note 4's) - the 'Global' network mode option disappears, as does the entire 'APN' button. Restoring to full 5.1.1 (non rooted, etc) resolves this. It appears that during the original setup wizard stage, something (Knox? License Agent? Dunno?) does something and then I can use my non-VZ SIM.
The same thing during a rooted/partial-system-5.1.1 (systemonlyN910V-5.1.1.tar) + factory reset, there is a 'Knox has stopped responding' and the SIM never seems to work, and the network mode options do not allow me to select Global, or input an APN (there is no APN button).
Same thing but *without* wiping "data" (ie, not selecting 'factory reset'), the SIM works, or rather I can select 'Global' as my network mode, and the APN options are available.
Unfortunately I also have to go thru the process of removing KingRoot and the other junk at this point.
My theory at this morning is that there is a setting on 'data' that Knox applies during the setup wizard(s) that affects how the network options work with a non-vz SIM.
I suspect that if you have a normal VZ SIM and go thru the root process above, you probably have limited (fixed) network options but they are the settings that work with vz.
Some or all of the above may be totally wrong - I'm learning daily and have lots of learning left to do.
Hello, thanks to my carelessness, I think I broke my dual sim functionality.
What I was doing was messing around in the network settings in Engineer mode that can be accessed using *#36446337#. And all of a sudden, both sims stopped working. After a lot of messing around with the RAT settings, I could get one of the sims working. After selection sim1 or sim2 in the options and changing the RAT settings for that sim, I can get said sim to work, but it breaks the other. No matter what I do, I can't get both working again. This was on Open Beta 9.
What I've tried doing since then:
1- Factory reset
2- Flashing another ROM (Lineage)
3- Flashing latest 4.0.4 firmware
nothing seems to get both sims to work. Always just 1 sim working. Does anyone have any thoughts what I could try?

Just do a full wipe with the unbrick tool and everything will be back to normal.
I have the same problem after I mess with the engineer mode.
Tried everything and still unsolved.
Try installing the modem or firmware of previous oxygen OS builds then updating the oxygen os

Yes, I tried the unbrick tool but it's still the same. It seems to me that the GSM/WCDMA band of the phone is broken. When put two LTE card into the phone, both can work under LTE band.

Installed the OOS3.0 and then updated to OOS4.0. Dual sim function won't work on both OS.
Flashing modem usually can solve signal lost on Samsung, but it seems that it won't work on Oneplus.

Well you just said you are a noob.. No problem but really dialing a number isn't going to break anything in your phone.. Wipe all partitions then Flash OOS 4.0.2 and o guarantee it will work, this is pure something in software level.
I have successfully fix the problem according to a post at Oneplus Community in China. Just Flash Official H2OS 2.5 (Android 6.0.1 ). Go to engineer mode. Choose Network Set -- Band mode --Hardware Default (Foreign) to fix the problem.
P.S. If you are in mainland China. Pls choose Hardware Default(China). Else choose (Foreign)
