Hello
I hope I am not the only one with the issue in which the device does not lock on LTE service consistently . It randomly switches between H/3G and sometimes randomly LTE shows up and drops back to H .
Users have reported it connects to LTE on reboot at times or by toggling data on/off to get LTE.
My current setup :
Stock ROM , 6.0.1 rooted with SuperSU 2.61 systemless and have tried both EX and stock kernel.
I just flashed the old 6.0 radio and will report findings when i move from my current location , its connected to LTE right now for the past few minutes.
Edit : Here is the issue tracker to report the issue to Google :
https://code.google.com/p/android/issues/detail?id=197102
I ADB sideloaded the OTA since I'm stock without root, and I've yet to have any LTE issues on 6.0.1.

same here i factory flashed clean all the images but the issue still persists
As I have mentioned in other threads , I am having this issue as well. On reboots the phone does not always connect to LTE. It will connect to 3G on Verizon and it will not switch over to LTE even though I am in a heavy LTE area. Switching airplane mode on and off will make it connect right onto LTE and there are no issues after that. However something is keeping it from connecting to LTE on reboots at times. It does not happen all the time. Sometimes you will reboot and it will connect to LTE without problem. I have seen reports on the canadian carriers, t - mobile, verizon and ATT. I believe it is probably fairly widespread however most do not notice it. A good way to test for it obviously would be to disconnect from Wifi and reboot your phone 5 or 6 times. See if it reboots to LTE signal every time...
I'm having this issue as well. It doesn't appear to be the radio either. I've tried reflashing the 2.15 radio from the previous build and I still have trouble connecting to LTE. Toggling airplane mode rarely helps for me. However if I switch APNs, then go back to the Nextgenphone APN, this often works. FYI, I'm on AT&T in the US.
Yea, definitely noticing the same issue on T-Mobile. Takes forever for LTE to connect after a restart, it just keeps switching between H and H+.
I'm going to go back to the 2.15 radio since I had zero issues with it and I don't rely on Band 12. If that fixes the problem then I'll wait for a new radio to be pushed out that fixes this annoyance.

For me the 2.15 radio made no difference. I think it's something system related.
I'm on T-Mobile and am seeing this problem. I mostly see the phone toggling between 3G and H (think I saw LTE Once).
I sideloaded the OTA to 6.0.1.
Edit: My LTE popped on after I left the phone alone for awhile. Not sure what the deal is, but something "funny" seems to be going on.
I have noticed that sometimes my wifi will turn off (Tasker toggles it based on certain criteria at times) and I will show the network strength meter, but no LTE indicator above it. Turning wifi back on and off again does not trigger LTE to connect. I have to go into Airplane mode, wait a few seconds then turn it off in order to get LTE to turn on. I am on Verizon stock systemless rooted with Xposed 6.0.1. Don't recall it doing this on 6.0 (any of the builds).

Interesting because over in the Chroma thread people on AT&T are saying that flashing back to the older radio fixes the LTE issue for them. I guess I'll just give it a try on my phone to see what happens and report back.
I'm on Verizon but I'm not having this problem. Fastboot flashed new bootloader, radio, vendor, boot, and system images. Then flashed Cataclysm + SuperSU 2.61 + EX 1.0. My phone is almost always connected to LTE, as it was before the update. I don't notice much difference between cell signal with the new radio.
Update: I just reverted to the older radio (2.15) and my phone connected to LTE immediately upon booting into Android. It also connected automatically to Wi-Fi Calling (I had to manually toggle it off then on to get it working on the 2.50 radio). However, I restarted just to double-check and this time the H/H+ problem cropped up again, but at least Wi-Fi Calling connected automatically. Sadly, resetting Network Settings nor refreshing the APN list solves the issue.
So while reverting to the older radio doesn't seem to fix the LTE issue on T-Mobile, I'm gonna stick with the older radio just because it fixes my issue with Wi-Fi Calling not connecting automatically. Looks like I'll have to just deal with LTE taking a few minutes to connect until it gets fixed by either Google or an XDA dev.
Edit: OK so this is weird. I just rebooted again and this time it connected to LTE immediately. Well, I guess downgrading to the old radio may be a good option if you don't need Band 12 support and are willing to put up with the phone only occasionally having the LTE glitch as opposed to always having the glitch.

Thank you. Have you tried rebooting about 5 times in a row to see if it boots to LTE every time? I am always connected to LTE as well but sometimes i must toggle airplane mode after a reboot because it sticks on 3G. Try being off of wifi and rebooting a hand full of times in a row to see if it always boots to LTE. Also, could you share a screenshot of your APN settings on Verizon possibly?
Anybody have the old radio handy so I don't have to download an entire system image?
I'm on ATT. For what its worth, my LTE hasn't reconnected at all for me. Just shows H.
I've rebooted like 3 times. I want to go back to the old radio to give it a shot and see if it works.

Tried it a few times as well, no dice. Whats funny is I let it sit for about 10 minutes, and eventually H connected to LTE. I'll try rebooting a few more times to see how quickly LTE connects.
Does the bootloader have to be unlocked to get the old radio back?
Interesting i just loaded 6.0.1 on stock no root, coming back from the reboot i only had 3g. Turned airplane on then off and now i have LTE. Seems like something is wrong with 6.0.1, this is on Verizon by the way.
Anyone know how to tell which radio is on your phone? I am on the latest chroma but not sure if the rom installs the new radio (I don't think it does). If it doesn't, anyone have a link to just the new radio?

since i had updated to the new radio my signal been dropping randomly out of no where then comes back.. i had about 20 drop calls since i had flashed to the new radio from haykuro blog and the magic spl. and then i had use JF adp1.5 and that when my E and bars stop dropping.. anyone out there know whats the problem? or is it just t-mobile towers
same thing happened to me. not sure what the issue was but i re-downloaded the radio file from htc, updated the pone and things were back to normal.....actually better.
after the update my signal strength improved. in areas i normally only get E coverage, i now get 3G. in areas i had marginal 3g coverage i now get more bars, etc
aiight cool, cause i was having the same exact issue...so I'm going to reapply the latest radio update...thanks guys.

Same here.So happy.
I was wondering where I can get the update for this?
I have had huge problems with the 1.5 radio for the Dream (2_22_19_26I) ever since upgrading. I even tried to reinstall the radio, to no avail. I still kept losing wifi every x minutes even though the status icon reported a strong signal, and the only way to get it to work again was to restart wifi manually. I also lost positioning via the 3G/GSM network after xx hours, and the only solution was to reboot the phone.
Anyways, I decided to revert back to the 1.1 radio, 1_22_14_11, which seems to have fixed these issues.
where can i get that old radio download?
HELP!!! updated radio now phone get no service!!!
i updated to the new radio just like everyone else then my phone starts dropping my data connection...NOW i reverted back to the 1.1 radio that i downloaded from htc and i still get no service!!! HELP!!!

Update:
Ok, so the old radio did not fix the problems, which means this is either an issue with Android 1.5/JFv1.50 or I have one or several apps installed that is causing this. A possible third option would be a funky SD card.
I've had my Nexus 4 for a few weeks now and have found that there appears to be a radio fault with my device. I originally thought it was a software bug but I've since rooted the device and flashed a new radio. I then installed CM10. Sadly none of the following have fixed the problem.
The problem is somewhat temperamental and the actual problem varies however is usually something like the following:
The phone boots up and has mobile signal without any problems.
However, it will then lose signal and the phone status menu will vary but usually says something like this:
Network: Unknown
Signal: -105 dBm 4 asu
Network Type: UNKNOWN:0
Service Status: Out of Service
In this state the signal indicator shows a hollow outline however I also get a problem where the network connects to 'Hutchison 3G UK' whereas when it works it will connect to '3', all other phones display '3' too. The signal indicator is solid gray with no blue bars in this state.
Switching Airplane Mode on and off doesn't fix it. The phone requires a full reboot to get the network back.
Is this a hardware fault? I'm going to drop into 3 tomorrow and get a new SIM to see if that fixes it.
Google doesn't appear to show anyone with similar issues so I don't really know what to do now.

Flash a stock factory image and see if you have constant coverage again, if it doesn`t help and the new simcard you may have to send it in for repair. Maybe the issue is antenna related.

When you say stock image is that just a stock ROM or is it an entire package that will reflash radio + recovery etc?

You can try flashing the latest .48 stock radio in CWM and see if it helps. Link http://d-h.st/8Jx. Unless you allready have it as CM doesn`t flash a radio or bootloader.

I have exactly the same issue. Please keep this thread updated. I have flashed different combinations of soft and got best results with baseband version .27 with stock 4.2.2, but gsm connection is still dropping. It gets disconnected when untouched.
Flashed the full stock image from Google.
Still having the same problem.
Do Google take returns from handsets not bought from Google Play?

Sent from my GT-I9003 using xda premium
I own a Verizon Motorola Razr M, bought in ebay to an US seller. I am in Spain and I use Movistar SIM card
The phone came with stock JB 4.1.2, and therefore I could not unlock the bootloader.
I started using it, but it had a problem that I am not been able to solve so far: after some hours of use, with no problems with GSM and data connections, it suddenly looses both connections, although the signals on the status bar still appear. I take care that signals have gone when I take the phone to make a call or surf the web.
I have tried the following procedures:
Change the net settings to GSM/UMTS
I rooted the phone with motochopper 1.1.2 exploit
I installed Safestrap 3.12 in order to be able to install other available locked compatible roms.
I tried these roms, following this thread here in XDA: Clean ROM 1.0. Clean ROM 1.1, Barebone New Base, Stock Deodexed.SDswap-Locked & UnLocked BLs-xt907-9.8.1Q-94-1, but no luck. This last one uses the last radio, but no way.
I also installed the [PATCH][GUIDE] Patch to fully enable GSM on Verizon CDMA Android phones. I could only install it on Clean ROM 1.1 however. It has been impossible to install it on the other ROMS. In any case, no luck again with the patch installed. Here I had a big problem because as I still had these problems, I got into *#*#4636#*#* in the dialer, and touched the band selection option: suddenly, the net showed no signal more and I was unable to make it work again: I finally solved this by installing the stock firmware from here with RSD lite.
No way. I still have this problem and I can not use the phone. I have also tried with another SIM card, but the problem remains. It is a shame because when the connection works, the phone runs very well.
Any help would be very appreciated

The problem also seems to become worse with the use of the phone: at the beginning, coming from a factory reset, It can last some hours before the problem occurs. But since it happens from the first time, it happens more and more frequently and the phone can not be used any more. It seems that there could be a software issue.
Another try disabling fast dormancy
I´ve just disabled fast dormancy, because my operator Movistar apparently does not use this technology.
For this, I have modified 3 lines from build.prop system file, as indicated in another site.
The 3 lines are:
ro.mot.ds.fastdormancy.disable=true
telephony.lteOnCdmaDevice=0
ro.telephony.default_network=3
Having fast dormancy enabled when your operator does not support it, seems to drain battery, and could cause other problems. That´s why I´ve done this. I have used root explorer apk from Google store, it is free and it automatically creates a backup of build.prop file when you modify it.
I keep the fingers crossed, let´s see what happens.
Fast dormancy: yes but...
After some days using the phone with fast dormancy disabled (for this, I also added this line to build.prop: ro.ril.fast.dormancy.rule=0 ; I read this for ICS Roms, I do not know if this command is also valid for JB, any comment will be welcome), I still get some cuts (less I would say), but at least the phone tries to restart the connections. For this, I have also installed the apk from Google Play called 3g reconnect.
In any case, any comment would be appreciated.
Issue not solved
I still get data and voice disconnections when I use GSM/UMTS or only UMTS modes. They occur ransomly, and they also occur as soon as I use a WIFI connection. I can only use the phone on GSM only mode, which is frustrating.
Any advise?

Hello,
I have tried both: using *#*#4636#*#* or using the usual phone settings. Sometimes I have also checked that the changes made with the usual settings appeared also dialing *#*#4636#*#*.
Yesterday evening, I tried selecting global mode instead of GSM/UMTS and it seemed to work for some hours, but today morming, the problem occured again. So far, the unique way I have found to avoid connection cuts off is using GSM ONLY mode. I have to say that I have tried with 2 different SIM cards but the result is identical.

What booby a trap? How many step into!
I don´t know if I am understanding you. I did that once because I did not know what else should I do to solve the problem. I saw that there was the possibility to choose theoritically between US bands and Cellular, and I entered in that menu. It is not so stupid to try that if you have already tried 100 other ways.
In any case, anybody has an idea about how to solve this problem? I´m sure I am not the unique person having this issue with this phone.

You are saying the problem is now still there. Yet the radio partition is fixed. Please restate what has been fixed with the rsd flash & what remains unfixed.
Well I think I have fixed and solved the problem: I initially copied the APN settings I had with my previous HTC Sensation, because the phone operator was the same (MOVISTAR), the SIM card too, and I have not moved. In these APN settings, the proxy was "undefined" as well as the proxy gate. I wonder if the radio stucks looking for a proxy each time or whatever. I tried yesterday with completely different APN settings, with a concrete Proxy and a gate... and now I have not had any issue in the past 24 hours. I will still wait a couple of days to see if that was finally the reason.
Which in any case would be silly, because I just applied what was working OK with my sensation, but...
New APN settings: let´s see

After several days, the problem is still there. After setting new values in APN, it happens less often, but it still happens. I have to switch to GSM only mode.
2 days ago, I was surfing the net at quite high speed with no interruptions, for half an hour. I then shutted off the screen, on again some seconds later, and the connection was blocked, I had to restart the phone. It has to be a software issue.
I finally sold the phone
After concluding that I could never get rid of this problem, I sold the phone, informing that he would have to use mainly GSM only connection. Great phone otherwise, but with this issue.
This sounds like a Baseband Issue.
Europe I have found baseband:
sm_bp_101031.027.32.81P to be the most stable so far, with no H+ support though.
But most Carriers in Europe don't have H+ or LTE.
That baseband is part of build 9.8.1Q-66
Which can be all downloaded here:
http://sbf.droid-developers.org/phone.php?device=8
The baseband from 98.16.1 had H+ support in Europe but connections dropped like crazy.
Same with 98.12.4, we remedied that with Aussie Radio at the time.
Maybe this may help some International users with Data and GSM Loss

I'm on 9.8.1Q-94-1(98.30.1.XT907.Verizon.en.US) and wanna use it in Germany. any experiences with the radio compared to the suggested one. Or is there another way to boost the performance of the razr m? Compared to my razr I the signal and data quality is really poor...
edit: my baseband-version is: SM_BP_101032.021.32.80P
edit2: ok... now i've flashed several basebands... and the behaviour of the phone is always the same... with the australian baseband of xt905 it wasn't possible to get an hspa-connection. dunno if its enough just to flash the radio-fw?!?!?
so is there an other way to get more stability in my region? i tried to flash the radio from razr hd retail germany. but i think the razr m don't like it when I fool around. actually I love the mobile, so i don't want to make it angry... your suggestions are very much appreciated...
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.

Oh, I can't switch from my carrier. And this particular issue just started occurring this week. I have been reading a few threads with different radio versions. I wonder if that will help.

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

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.

It's strange because this happened just this week. It was fine before this week. Everything worked, I got proper signal strength and the connection never dropped. Now on my commutes I can see there is no network when I am driving, no maps, no spotify nothing.

Okay, I guess that's what I am doing today. I haven't modded my phone in any way, I am still on stock android. I am going to have to start by unlocking bootloader and flashing TWRP.
Good luck. I was in the same boat. It just stopped working but there was no Rom update that could have caused a problem.

Where do I find the old versions? This thread doesn't have the old versions anymore. 03.79 doesn't resolve the issue.
EDIT: I used 03.75 and that doesn't do it either. Time to try 03.72. I am so disheartened.

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?
Just as the title states, I'm having major issues with wifi. It's the phone, it's not the network or router because it works well with all of my other devices. I've tried resetting the router anyway, I've removed the network information in the phone and reentered it. The only thing I think that might have affected it without me knowing at the time was when I left the phone in my car and it overheated. I actually did that twice. If that is what caused the issue then I think I'm out of luck and it's likely not repairable. My first thought was the wifi antenna or something but because it does still connect I don't think that's it. Anyone else have this happen?
How you check your WiFi preferences?
By default WiFi disconnects after certain time...
Make sure is set to "NEVER"
Does it say "Connected, no Internet" and then disconnects and tries to connect again?
Is it switching to 4G because better signal? Turn off aggressive wifi handover in developer options if set. Check other settings too.
Turn off mobile data and see if behaviour is different as a quick test.

I can not find this setting, what menu is it under? I checked in Wi-Fi settings and Wi-Fi>Advanced. I've had the phone for some time now, this happened all of a sudden.

In the notification bar it would still show Wi-Fi signal status (on, with full bars) but it would go from displaying "network name" to simply displaying "Wi-Fi". If I long press it takes me to Wi-Fi setting and I can reconnect manually. If I turn wifi off and back on then it DOES NOT auto connect back to the network, despite the fact that the network is saved.

It happens when I have full Wi-Fi signal. Auto switching is apparently turned off, as mentioned above. When I turn off mobile data, it still disconnects from the network, leaving me with no data connection at all. Developer options were off, but I turned it on and checked but that option is off.

What Android are you using?
You could update to 7 / 8.0.0 US Beta or use a custom like me. Im currently on Android 9 Treble Pixel Experience and its working nice.

I'm running 7.1.1, B35. It would be nice if it was just a software issue, although I hate having to back everything up and wipe it. I haven't been keeping up with development, how reliable are A2017U flashes now? I think I remember them being risky with this phone when I first got it. Is any functionality lost? I would prefer to wait for the OTA 8.0 update since it seems to be coming but maybe...
I'm having this problem but mine says that the wifi manager has disabled wifi permanently. I can start it manually and it will connect to the internet for a few minutes then revert back to disabled. This happened after the 7.1.1 update.

ZTE Germany just released a message on their Facebook saying they're in their last stages of testing the Android 8.0 Oreo beta and will release it officially soon. This can be as long as one to three months away, or even longer.
If you're running stock, then flashing a custom rom will provide you with more functionality and performance. Battery life will definitely be shorter though, so say if you're getting 6-7 hours of Screen-on-Time on stock 7.1, you'll get around 4-5 on a custom rom. This entirely depends on your usage however. Flashing custom roms is quite easy and risk-free if you know what you're doing, and follow a good guide. Check Oki's guide on how to flash an 8.1 treble rom if you'd like. The current LineageOS 15 and 16 builds drain quite a lot of battery compared to other roms. If you'd like a good and stable Android 8.1 Rom, I'd recommend NFound's AEX 5.8. If you're like some of us (me included), you can live life on the cutting-edge and flash a Android 9 Pie rom. I wouldn't recommend it though as unless you know what you're doing with a GSI, DON'T flash one.
Always backup before attempting anything.
Same issue

A few weeks ago my Axon 7 started doing the exact same thing that you describe. Were you able to find a solution?
Same for me, I'm having the exact same issue.
Did any one of you find the solution for it? :/
