Hi all, I had lost my IMEI information and I managed to fix this using the QCN file for the 2014811 variant but this QCN has no support for Brazilian LTE bands cos my variant is 2014819 so all I get now is H+ internet. Does anyone here have the original qcn file for the brazilian variant so I can re-edit with my IMEI and get 4G back? Thanks in advance.
Are you having signal drops after flash the QCN? I'm having since then, don't know if is hardware or not. I don't want to send to assistance and my warranty is almost over.
Yes

Yes, on TIM the signal dropped but because at home 4G signal is stronger than 3G where I live but on Oi, 3G signal is real strong. I want 4G back and I can't seem to find the original QCN for the Brazilian variant.

Where I live there's only 3G so I don't know about 4G.
What I mean with signal drop is not the strenght and yes the signal itself. Sometimes I have no signal with the message "no sim card detected" than I've to turn on/off airplane mode some times to come back.
I don't have that issue

Oh no I don't get that, my sim card is always detected after I flashed the cqn but since this one is for Indian variants, I get no 4G, and my problem now is finding the cqn for the 2014819 variant, I have no friends with this cell phone so it gets difficult. You should reflash that if you say it used to work better before.

Well I've tried fastboot flashing and still I'm here with that issue without a fix, so it doesn't always override some settings. Try the IMEI fix stuff on the Miui forum.

Have you tried sim cards of other carriers? Do they work or still the same? You should send in to assistance before your warranty runs out. Mine has expired, that's why I don't send mine in.

I was told they fix this in a week, they'll probably send you a brand new phone. It's worth waiting for a week and get it fixed than never get it fixed.

Hi,
Ok, so I dont have a network signal now.
This started to happen when I dropped my nexus 4.
It was ok until I dropped the phone. I suspected that it really was a hardware problem, the software seems to get signal.
Here are the screen shots I took when I dial *#*#4636#*#*.
I tried changing wcdma preffered to wcdma only and back again to wcdma preffered again, nada.
See, there is a signal. I suspected the sim card so I bought another one. But still, no joy.
I also went back to all stock (latest), coming from cm10.1. I formated everything, but I still get the "emergency calls only".
This really bugs me out. I can access the sim card (contacts in it, sim services, it all works). I also get signal levels like other phones outside of a building (around -54dBm).
So why, just why wouldn't it work? please give me ideas.. My last hope is to take it to an lg store, but since I am in a different country where I bought it, I guess I won't be able to get any warranty (it was bought by my brother).

If u didn't have access to the sim card I would say that it may have moved, but if u do I am sure it is a hardware problem. If the phone doesn't have dropping singals u could not have any charge by sending it to the SAT.
Good luck!

That's the very reason I'm baffled. the phone is perfectly fine except for the signal. If it's hardware, then shouldn't I get a waaayy lower signal levels?
AND!!!!! I can freaking search for available networks, I CAN DETECT THEM. That really freaks me out.
If it really is the hardware, what is it? I recon the radio/antenna is fine since i can detect signals and networks, I also believe that the radio controllers are integrated to the processor SOIC. Sheeesssshhhhh..... I'm enticed to prop the thing open, maybe some just loose ribbon connection or.. sumthin..

Ever since I got this phone i never once get any service i thought maybe the bored was done for but today I went into the town area and was surprised to see 3 to 4 signal bars on it i tried making a call and it worked, even sent an text message and it worked, funny thing now when I came back home I then again have no service bars whatsoever so I went back into town to see if I would get back signal again and i did..... Went back home for the second time and now no signal again, anyone know what might be the problem, I'm on slim rom 4.4.2 baseband XXUFNA5

Do you have a bad signal inside your home? Signal inside a house can never be guaranteed as there are many factors that affect signal strength - especially indoors.
I have an S3 and I get very good signal on that at home it's just something wrong with the S4 but i just don't know what... I get not one bar on it any else where, only when I go into town area

when you connect downtown, do you know what network you are (2G, 3G, LTE)?
It might be that near your home you only have (for example) 2G, but your phone is set to search for 3G only.
So I tried different modems and I flashed stock rom twice and still no luck, any other suggestions please

We might have a very similar issue, I also don't have a solution (yet).
My phone does not connect to 3G, only 2G and LTE.
To check if you are in the same situation:
*#2263#
then play a little with the settings there... (for example try 3G only).
see if you get any positive things out of this.
(as a note: in some of the options I can connect to 3G, BUT I cannot make or receive any calls - internet is working though). You can choose a single option only (try each 2G, 3G, LTE and see what happens). However, I strongly suggest to keep a combination of 2, see the note above).

Yes, its possible. Use Odin 3.0.7 or 3.0.9 and flash DBT (German) or BTU (UK) ROM. After flashing boot it up (but don't set up) and do hard reset either from Menu or use key combos.

This is when I'm in town today, full signal

And now I'm out of town, what could possibly be the problem, gosh this one is hard to figure, I don't think anything is wrong with the main board
Guess I'm gonna have to change the board since no one has any ideas of my problem

The answer is in your picture of being in town. You are only connecting on EDGE. So my guess would be that you have bad coverage in that area, ie weak signal and no LTE.
Check your providers coverage map.
Hi, in these days I'm having troubles with my Galaxy s5 data (h+).
In the status bar I can see the H+ signal, it works with google chrome or other apps, but if I try sending a message with whatsapp or telegram, it wait at least 5 or 6 seconds before sending it (no V sign, only the clock.
Today I tried doing a soft reset by recovery but I didn't solved anything.
I don't know what's the problem just because it seems to go well in other apps.
Edit:
I noticed the same problem happens with WiFi, so that's not a 3g data problem but just the phone.
What can I do?
Try a different modem

IDK perhaps the modem for your region is bad. Please be aware it could also be your carrier doesn't play nice with your device, especially if you got an import or something

I've posted a few times about the poor connectivity on my EU model Axon 7. I've given up expecting it to connect to a 4G signal, it just refuses.
However, when I'm on WiFi, the 3G symbol keeps flicking on and off. I thought this was a bug fixed by the B03 update.
If someone who understands these things cares to watch, I've done a screen grab of this thing as it switches signal. Is this normal? It looks very busy...https://youtu.be/jDuioJX2uoI

Mine is working fine but it connects to LTE most of the time. I haven't experience such issue. Model number is P996A04. What is yours? Otherwise I have heard that not quite ok SIM card can cause such problem. Do you have original nano card from provider or did you cut it?

I'm going to send it back now and try a Nexus 6p for a while. Might buy it again if I read there's been improvements.
Hello everyone!
I am having a very hard time diagnosing an issue with my Nexus 6P. Android 7.1.1 Angler-03.78 Build: N4F26T on AT&T unlocked. My network keeps dropping consistently. It works fine for about 5-7 minutes after a reboot or after toggling Airplane Mode. It goes on to attach itself to LTE and then subsequently drops to HSDPA/3G and then just outright loses network. It intermittently then comes back but usually hangs on to HSDPA/3G and the voice quality and data speed are just terrible.
I tried the SIM in my old Galaxy nexus (which doesn't support LTE unfortunately) and the network didn't drop. So I am convinced something is going on with the phone. This issue crept up this last Monday (03/26) and has been going on ever since. Has anyone had similar issues? If not, could anyone tell me how to diagnose this issue before I have to send it to Huawei? Because I am not very keen on sending away the only proper handset I have.
Thanks
I had a similar problem on Cricket, which uses AT&T's network. I never had good cell coverage in my apartment but it suddenly got so bad that I could only make and receive calls in certain rooms. Cricket wasn't able to diagnose the issue and I ended up switching my service to Project Fi. The problem completely went away. I now have a strong cell signal with full bars everywhere in my apartment. I'm not sure that sending your phone back to Huawei will actually solve anything but good luck.

This is a known issue just this month I experienced it myself, Try flashing different radios I was on 03.78 and had signal drop issues 03.72 and 03.75 have had the best results.
I flashed radio 3.7.5 and it did zip for me. I was on Sprint where I never had any problems and switched to AT&T when I got the 6P and never got more than half the bars strength when the service was actually working. After I switched to Project Fi I am usually on the T-Mobile network and get full bar strength 100% of the time at home. If I use Signal Spy to manually switch to Sprint I still get full bar strength in every room in my apartment. This is with the exact same radio that I had problems with on AT&T. I don't know if the 6P doesn't play nice with certain networks or if those networks provide inferior coverage but Verizon users have had notorious problems with this phone that caused Google to issue a separate radio just for them. Verizon customers are the ones who claimed to benefit from flashing radio 3.7.5. I have never heard of that actually helping anyone else and it definitely didn't help me. If the problem is partly with your network then sending the phone back to Huawei won't make any difference. You can try flashing a different radio but in the end you might have to switch carriers and if you can't do that you might need to switch to a phone that your carrier actually recommends.

Why not go to AT&T first, let them know about your issue and have them provision a new SIM for your phone (free). I seriously doubt a different radio is going to solve your problem, but if you want to try there is a dedicated thread in General for flashable bootloader/radio zips, but you would be better served installing ADB/Fastboot on your PC and using fastboot to flash them yourself. The latest radio is 03.81 (from 7.1.2) The stock image files on Google contain the radio and bootloader img files. If the new SIM doesn't fix it, you may end up backing up your data and doing a factory reset.

Okay the latest factory ROM didn't work, I did a complete wipe and a factory reset. I will go to AT&T tomorrow and see if a new sim helps (I doubt it because this SIM works fine in my backup phone Galaxy Nexus but I can't verify LTE with that).
I don't know what my options will be after this. I feel like I am spending more time maintaining my phone instead of using it. Just disappointed, that's all.

Yeah, I found it. Thank you. None of the versions helped though
I've been experiencing signal problems when downgrading which is not your case. But I got it solved by performing a factory reset. It's fairly straightforward once you have backed up your data. Worth a try?
Similar problem here I think I have found part of the problem
I have been having a similar problem ever since a recent update. I have tried everything found in this post. Recently I tried turning off my wifi and noticed the problem seems to go away. I have done a few searches to see if anyone has reported no phone with wifi on, none of the results so far have been very helpful.
Since I don't want to be without wifi, I have gone into the developer options and turned on cellular data always active, to see if this helps, so far this is working for me.

I did try that but it didn't work unfortunately. I called up Google and they sent me a refurb which was DOA but then later they sent me a new one which works just fine. So it was definitely a hardware issue on my old phone. I don't plan on updating my software because I just want this phone to work like a phone.

It happened either way. Wifi status didn't affect my issue. It used to die out completely. Google just sent me a new replacement (after a DOA refurb) and it seems to be holding. But I am not upgrading to 7.1.1 because I feel the issue might crop up again. So I am going to stick to 6.0 for now.
Update on my status
So far having wifi off has worked, until I ran Waze and then both GPS and Networking down till I quit and turned Airplane mode on and off. The previous change to Developer setting did not work.
I have been debating going back down to 6.*, has anyone had good results with this?
