Hi there,
Excuse the novice. Just got this 2 days ago and I am still trying to figure it out why I can't access the net at all.
I have not got Android experience much and I am digging now how to come out of this situation.
So no option to access Net at all. The Error in response is " Couldn't sign in. There was communicating problem with Google servers . Try again later." So this is like a loop there.
Android Version -5.1
Baseband Varsion - MOLY.LR9.W1444.MD.LWTG.MP.V16.P10
Kernel Version - 3.10.65
Build Number -ALPS.L1.MP3.V2_NB6753.65U.L1_P22
Custom Build Version - Elephone_P8000_20151014
I must admit the Phone came preset and once I have switch it on it picked up GMT time without I have set anything.
I will appreciate any help or pointing to a resources to try to solve as now it is unusable as I can't download anything.
Thanks in advance.
Check:
Settings --> Data Usage --> (cellular provider tab) --> toggle 'enable mobile data'
See if that's the issue. Good luck.
Now Stacked to The Elephone Logo on and unresponsive.

Thanks kevvyboy,
I can't do anything right now. The phone by itself (really) got in a mode I can't read even with letters so small, went to the Android Man with red Mark and now is in front of me unresponsive with the logo of Elephone totaly unresponsive.
Just to underline - I have not touch anything- I have left it on stand by last time I have played with it.
Any clues and help please will be much appreciated.
PS. NOW I have managed to (I guess Switched it off) and again on and there was window with APP UPDATE - came to 116 out of 116 updated and now again can't access the net neither Google Play.
Could this be a OTA Update completed somehow?
Thanks everyone in advance!

Hi again,
I have enabled the cellular data - no luck again.
When I am trying google play again message Google servers can't be reached and the more interesting - using the - preload browser it try to search trough yahoo search. This phone was sold to me as new, but I am starting to wonder what it has been through before it reached me?
Will a flash using PhilZ Recovery will help?
Could someone point me the way out of this please?
Thanks!
New bizarre Message.
Hi again,
Just to make it more interesting out of the blue it Popped up a Message box with following wording.
"In a Previous Android Version You have disabled all Google App services. Do you want to enable them. Yes/NO,
Of course I have chosen Yes and Again Can't reach net neither via Cellular data nor Wi-Fi.
Any useful contribution will be much appreciated.
Thanks!
Stuck on Airplane Mode? Try toggling it on and off. I remember my HTC OneX having an Airplane Mode issue - had to toggle on / off several times and reboot.
ETA - faulty APN settings for your provider? May explain a mobile data issue, but doesn't address the wifi issue.
Dammit.
Got It Work on Cellular

Thanks Kevvyboy for your contribution.
Somehow I have managed to get the Cellular data connected and now have updated the Google Service.
WI-FI still an issue. Is there any sense - updating a driver (if I am not asking stupid question here)?
Thanks!
Glad to hear at least cellular working! The wifi issue is a bit of a mystery to me though - I'm all out of smart ideas, sorry
Hopefully some other bright soul can chip in.

download drivers for SP flash tools and SP flash tools program.
go and download mediatek drivers and sp flash tool.
you can get these from elephones website, google or where ever. i got mind from needarom. i used the latest versions for both.
i downloaded the 5th November 2015 firmware from elephones rom. it came pre 7-zipped. i unzipped it and left it's structure.
installing the drivers part:
you need to disable signature enforcement in your OS to install the drivers.
open SP flash tools.
load the scatter file in the official rom folder you unzipped with 7 zip.
at this point press the download button in SP tools.
switch off your phone. connect the usb cable to the phone and the computer.
you should now have the latest firmware on you phone when complete.
please note it wipes everything, so back up anything important to you.
once done, set up your apn in settings, mobile networks, access points.
wifi should work after a clean factory reset if you don't have a dodgy device.
elephone only supports 2.4ghz for wifi as far as a i know.
also make sure your network bands and are supported by the p8000.

Hi El_Nino9,
Thank you for the reply and sorry I am delaying my response. I have actually done some of the suggested previously once I read more on the site - thanks for the contributors here. I had Eragon 9.5.0 Custom ROM set with Philiz recovery tool after Mediatek driver download but the wi-fi is still an issue.
I will try to perform the the one suggested from you, I just have located the latest Elephone p8000 ROM on the Elephone site and will perform this on a first chance I have. - most probably on Friday.
Thanks once again and I will post an update from the outcome.
OK!
I have done the upgrade to the 05.11.15 Stock ROM.
Have made a Factory Reset and the Wi-Fi is working as before but I can't reach internet basically.
Again after attempts to get to Play Store or to or to perform a simple Google Search it comes again after message "Just a second" and after 20- 30 seconds it end up with the message.
"Google Server can't be reached at the moment please try again later."
Any help on this will be much appreciated!
Thanks a lot in advance!
P.S>
I have just discovered that the icon of the WI - FI showing a processes going on but I can't reach My Router URL for example through the Local network.
Does it mean this is really dodgy unit or I am missing any settings or there is any cure for this?
Thanks again!

so your mobile data still works on the latest firmware? specially after typing the correct apn settings?
regarding your wifi, where is the router in relation to your position? far away? standing right next to it with the phone? whats your encryption for your wifi? tried changing that to a different type and seeing if it connects?
if you have big concrete walls and live in a nice solid building that may too cause signal not to reach. the wifi isn't that great on the device speaking from experiance in comparison to other devices.
if all fails... possibly dodgy device

Hi EL_Nino9,
I guess either the p8000 not like my D-LinkDIR-655 router or I am missing something in general.
I have an extension for the other rooms and the phone connecting to a simple TP-Link with no hassle at all, but D-Link is like a brick wall - you see the wi-fy working but no internet access.
It is still a mystery.
At least is proven the wi-fi module is working.
Believe me - I have tried to alter the setting on the route and still can't get to the net content.
Will keep exploring this and will report if any luck.
Thnaks!
I´m facing the same issue here. Google-Services like Google-Photo, Gdrive, Inbox are not working. Any solutions so far?
Looks Like I have rooter WI-FI issues

Hi kraftmaschine - I have discovered that my aged D-LInk DIR-655 was giving me problems dropping out the signal. I had an access through mobile network and through my other room extension rooter, so I got on mind either compatibility issue or router problem. So I have upgraded the router and voila. Everything got sorted.
Also upgrade to the latest mod - not OWA but using the standard methods described here.
Hope that helps.
I picked up a Sprint prepaid HTC 816 recently and decided to flash this rom below
[ROM][UNOFFICIAL][CM12.1][5.1.1][VirginMobileUS][A5][single sim][1/1/2016 security]
That one
It installed great, had everything everything working after I added my Sprint APN settings. The phone still displayed it as Virgin Mobile and only 3g seemed to be working. But I was making and receiving calls, text messages and had mobile data.
Fast forward a couple of hours, I installed a custom theme from the Play store, rebooted and ever since then I lost the ability to pickup a network signal and access my APN settings.
If I re-seat the sim and toggle airplane mode it will pickup a network signal and I can regain apn setting access again but it drops within minutes.
Ive reflashed the rom, wiped everything reflashed again, same thing. Any ideas on what has happened?
Thanks and appreciate your time!

Are these the APN codes you used(poster corrected a mistake in green text)? Looks like there is a different APN for prepaid /postpaid.
http://androidforums.com/threads/working-sprint-prepaid-apn-settings.920752/
I indeed use the apn settings in the green from that post. They were working fine until I had a reboot. Then everything went to ****. It wont even let me access the apn settings and when I can its briefly and then I lose signal and apn access.

I had an issue with something on my Virgin mobile 816 a5_chl a while back and a member @wxppro was very knowledgeable about APN settings and their intricacies. He had a MVNO 816 at the time with an APN issue and I bet he could help you with this as that was my best suggestion for a fix and it didn't help you.
See if you can direct him here to this forum so that if he can help out the info is here to help others as well. Good luck.
Not sure how much I can help. APN is a tricky business. If your APN settings disappear after some time, it is generally because the cellular network the phone connects to does not match the APN's MCC/MNC numbers. Or it could be the phone is in 3G mode (CDMA EvDo mode).
You can try these things:
Switch network types, from LTE to 3G, wait a minute, and then back to LTE. APNs do not show up in 3G mode. They only show up in LTE (or global) mode.
When you have the APNs show up, check the parameters are correct, you can do a "Restore to default" and then add the new one following that post.
Hope this helps.
I'm having a similar issue as well (except on virgin mobile)
A month ago I flashed squid's version of CM 13 on my phone and everything was fine for a few days, until I completely lost LTE and access to APNs. I reverted to stock and still was unable to get LTE, although I could get a shaky 3g connection if I changed the network mode to CDMA only. I called virgin mobile and they walked me through the troubleshooting steps and eventually determined it was a network outage (even though two desires in my house belonging to other family members had LTE). I called again after they verified that the network was working again and they were still unable to fix the issue.
Recently, a friend upgraded from a desire to a different phone on a different network, and gave me his old phone. I plugged in my sim card and activated this new phone and I got LTE. Figuring everything was good, I decided to flash squid's ROM once again. The same issue happened, I got LTE for a day or two until it cut out service again. No access to APNs, not even any service in stock or on the official build of CM12 with the APN fix (I can't access APNs there either). I'm out of ideas and would appreciate if anyone had any input on my issues.

I have this same phone a5_chl Virgin Mobile. Did you factory reset your device before flashing back to your stock rom? The other thing is and this is just my opinion not a statement of fact or a knock on the wonderful Bigsupersquid but that 13 CM ROM is nowhere close to being stable enough for me to risk flashing it to my daily driver phone. Just read all the posts and his candid responses. You were basically a beta tester .
I'm not an expert in APN's but if you can't get that fixed your last resort might have to be wiping your system and then flashing or running the executable RUU (rom utility upgrade) file found for our device on HTC/downloads . This is a last resort option and wiping your system will remove your existing firmware so have the correct RUU for your phone downloaded to your computer before attempting a wipe. If it's an exe, which I believe the U.S. Virgin Mobile one is ,you will hook up your phone fully charged in fastboot mode then from your computer run the exe RUU like any other exe executable program and wait. It will reformat all partitions and reinstall pure stock ROM. Hope someone else had an easier fix for your data issues and good luck.
EDIT: you will need your stock recovery flashed back and a relocked bootloader before flashing the RUU but I've read that some have flashed their RUU over a custom recovery with a locked bootloader and it wrote over the custom recovery with the stock recovery. I have never personally tried this just the first way I mentioned and that worked for me.

I did try factory resetting and I am on stock after flashing the RUU. It makes no sense as the RUU should have reset everything. That perplexes me the most

OK then you did get back to stock not from a nandroid backup but from flashing or running exe stock RUU? If that's the case then it replaced everything that might have been changed and your issues shouldn't be related to any APN changes. You also removed and reinserted your sim card as I believe, correct?

i posted about my lte issues i had for nearly two weeks, running stock just to verify the data service problem wasn't my rom...
i had to install stock recovery, relock bootloader, download the ruu.exe from htc and extract the .img file in Wine, then rename it onto the sdcard and reboot into hboot so it'd flash. neither Wine nor virtualbox xp talk correctly to any of my phones over usb. and i wasn't about to native install Windoze.
factory reset stock didn't fix it, even trying activation, update profile, etc.
i learned i could get 3g data but switching to lte instead of cdma shut down data entirely.
virgin eventually directly escalated me to tier 2 tech support in my last call, they sent a couple service programming pushes to the phone that got my lte back online.
i tried the various service programming menu options repeatedly, with no results but the prl updated once; but the trigger to fix my lte seemed to come from upstream.
i tried various apns, in cm12, cm13, and stock lollipop. rebuilt init_a5.cpp with different mccmnc and adjusted apns. i really tried most tricks in the book plus a few more.
as far as alpha testing goes, at this point I'm just sharing something cool... i always enjoyed flashing latest greatest on my ov way before i was building.
not too many actual logs to really bug report for either rom.

Some of that was over my head but happily not all of it. Basically what your saying is the fix needs to come from the carrier and it's a reset issue on their end not a custom rom issue? By the way I'm a big fan of your work. Hell I might be on one of your older ROMs right now I've flashed so many I forget. Thanks for the education.

The first time it happened, I flashed back to stock using the RUU.exe. I tried again but the second time I took out the SIM card before running the program, I still can't get LTE.

It does sound a lot like a carrier/account issue as I managed to kill 2 different 816s. I don't think it's the SIM card itself because I put it into a 3rd phone and got LTE, although since it was someone else's phone, I didn' t bother activating it.
I guess you got lucky with support, I tried talking to them and they tried the same thing with me. Although all I got was excuses saying they're logging a ticket with their "network engineers" and to call back in a few days. This continued on for a few weeks until they determined I needed a new phone, which I was also bounced around for another few weeks (I still don't have it).
I'm just completely lost now. I'm almost certain it's my account and it needs to be reset, but I can't get a tech who can help me. How did you manage to get someone in tier 2?

This is starting to scare me as well because I'm thinking of going back to stock once Marshmallow gets pushed to our phone to get my beats drivers back and this is making me think twice. Sorry your having so much trouble.

seemed that way.
i took radio logs before and after it worked, and worked only on 3g, and it looked to me like the sim card responded differently to the ril after things were running right again.
mine might've been a special case, though, it came from ebay with no sim, and virgin had to go to a little effort to get it programmed when i installed the sim initially.
they also claimed for several days that the local Sprint tower was down for lte service.

tier 2 takes luck, time, many calls, and eventually you learn the answers to all the questions tier 1 outsourced from India asks so you can feed it to them so fast they want to shuffle you along. takes a couple of weeks to over a month to get to tier 2 and sometimes they have to be involved multiple times as well.
I've been dealing with virgin since 2009... replaced only two phones, eventually got the rest of the issues hammered out with persistence.
for a little while, twice, i had direct toll free numbers to American tier two even because my issues were so hard to solve. it didn't take too long for those numbers to be disconnected, though.
So the problem I'm having with my G3 is that the Network either drops and comes back repeatedly or completely drops and does not return. This only happens on 4G. When I go into network settings and change network mode to 3G it works fine and I get a constant signal all the time.
I have been using Fulmics ROM and I thought maybe that was the issue. But it wasn't.
I tried 3 different sims from three different carriers (Three, EE, O2) on several stock firmwares. (20N, 21C, 30A, 30F).
Each scenario is the same; network drops when phone is on 4G network mode, but its fine on 3G mode.
However, I have noticed that if I leave Wifi OFF allowing 4G data to connect first, then its fine. I can even turn Wifi ON again and the network is stable. I can even turn Wifi and Data OFF and the network is still stable.
But, if I toggle aeroplane mode, where Wifi connects first or where Wifi and Data is turned OFF; I am back to the network dropping.
Also, I live in London UK so there should not be any signal issues. Can anyone tell me why this is happening. I doubt it's software issue as I've tried several firmwares.
Any help is appreciated.
Mate I'm afraid there is a high possibility it's the Fulmics ROM.. I'm still trying to read up on the issue myslef, there's a ton of reports in the Fulmics thread and around.

I'm using an UK bought LG G3 as well (from Three) and started experiencing similiar issues after I flashed Fulmics. Even tried rolling back to 4.4.2 using a .tot file but didn't really help me.
Still scouring all around trying to find how to fix the issue..

Mate I'm afraid there is a high possibility it's the Fulmics ROM.. I'm still trying to read up on the issue myslef, there's a ton of reports in the Fulmics thread and around.

I'm using an UK bought LG G3 as well (from Three) and started experiencing similiar issues after I flashed Fulmics. Even tried rolling back to 4.4.2 using a .tot file but didn't really help me.

Hmmm looking back now this issue did start when I first installed fulmics 3.5. But shouldn't everything revert back to stock when you reinstall stock firmware.

That's what I thought but I guess it's a little bit more tricky.
Anyways I think I managed to restore some kind of stability in the signal, still unsure about the process though. Seems that different stuff are working for different people. In a few days I hope to have some information to give you how to fix it.
In the meantime try checking the Fulmics thread for ideas and suggestions (that's where I start off from).

Yeah let me know when you find a fix. Really appreciate the help.
One thing that is sort of a temporary fix for me, works on Three, EE and O2 (only ones i tried), is connecting Data first when on 4G mode.
So if I toggle airplane mode and if Wifi connects first then the network drops or keeps refreshing.
But, if I leave Wifi OFF and Data establishes a connection; the network is stable and I can then turn Wifi On again and the network will remain stable.
I just have to make sure the network does not lose connection (i.e. tunnel or airplane mode), and if it does ensure Data connects first.
Also, another thing. After I reinstalled Fulmic 5.3 it seems 4G mode is sort of stable. As in when on 4G mode instead of dropping the network it connects via 3G automatically. But this only happens with Three.

Okay here is what worked for me - open this guide and download the Three specifiic Lollipop and Marshmallow .kdz files.
Flash the stock Marshmallow firmware first using the LG Flash Tool method. Your phone probably won't automatically get recognized since you're running Fulmics now so you'll need to change the COM port as described in post #
After that downgrade to stock Lollipop using the LGUP method. Personally I downloaded more updated (I think, not sure) files from here.
Then I proceeded to re-root and clean install Fulmics 5.1 and the 5.2 and 5.3 OTA updates from recovery. Booted and network works without drops now with 4G connectivity.

I changed my carrier and got an automatic SMS with configuration for my phone and instructions to save it. I should've known something was fishy when I recieved the "congratulations for setting up" message even before I recieved the actual settings. Anyways 4G was running fine on my new carrier with 32 mbps speed which is okay, much better compared to the same carrier 3G network, however I only had 3 bars of connection so I gussed what the heck, I should save that configuration after all, it might make things better. What a bloody mistake. I lost 4G connectivity and my phone refused to connect to the 4G network, only 3G (just as you describe).
What worked for me in this scenario was wiping the cache and dalvik (not really sure this step is even necessary to be honest, but I was headed for a full rom re-wipe anyway and decided to try with this first), going into the hidden menu and choosing LTE only connectivity (Fulmics Tweaks -> Hidden Menu [or the hidden code for the phone app if you decided to stay on stock, which I dont have] -> Modem Protocol -> RAT Selection -> LTE only. At this step my phone got to the usual 3 to 4 bars of connectiviy but was displaying "Emergency mode only" and no data at all. I proceeded to Settings -> Networks -> More -> Mobile Networks -> Access point names -> Reset to default from the menu. If network mode doesn't change back to GSM/WCDMA/LTE auto automatically, change it back manually. At this point I had restored back my 4G connection and everything is working normally (30-32 mbps connection stationary in my house through a wifi hotspot next to my laptop).
Good luck, I would follow the steps as described just in case. I tried many reflashes before that should've worked but didn't for me. However different things work for different people, hope this works for you and please report back

I'd like to thank you so much for this information! I was having signal drop issue after installing Fulmics ROM. Tried to flash stock ROM but no success. After doing the downgrade via LGUP method to LP my phone is getting full signal again (at least I didn't notice any drop until now).
Thank you!

Sorry for the late reply.
I followed your instructions and unfortunately it didn't work. :crying:
I first tried with the D85520f you provided and then with an updated D85521C firmware. But nothing worked.
The temporary fix, which I found works, is to ensure 4G mobile data establishes a connection first before Wifi (turn Wifi OFF then ON after data established). Then there is no signal drop until I go through a tunnel or phone restarts (signal drops completely), which means again i have to ensure 4G mobile data establishes a connection before Wifi or else it'll go back to the constant signal dropping.
Guess I'll just stick with 3G at all times. I've spent too much time trying to correct this than actually finding enjoyment in using the phone.
Anyway really appreciate the time and effort you took to help with this annoying situation. :good::good::good:

Modem 21C should be your answer! Please try with that.
Is anyone still out there

I flashed dummies and get dropped 4g data like this.
I have tot back to stock and didn't help... not Kdz
Haven't downgraded yet to LP yet.
On turborom now.
Can I just flash this modem? Have a link to the 21c modem?
Flash in twrp or send via LG flash?
I have the Honor 7x, and recently update to the 8.0 Oreo android update. Immediately after the installed the update in the morning, I noticed that my mobile data was no longer working correctly.
Wifi can connect, I can make phone calls, send text, literally everything else about the phone works perfectly.
A day later I got another update 8.0.0.332, however I am still unable to access my mobile data.
I use At t for my phone service, and do not have any damage to the phone (havent dropped the phone, water damage, etc).
My friend has the exact same phone, with the exact same phone service, and got his update the same day without having any issues.
Thing I have tried in attempt to fix the problem already based on google searches:
I have tried turning my phone into airplane mode, waiting, turning off airplane mode (also with trying a hard reset on the phone).
I have switched my simcard to slot 2.
I have put my simcard in another phone, and verified that the sim card is still working properly (the other phone was able to access data just perfectly).
I have tried turning off 4G data, and putting it back on.
I have tried resetting the APN back to default.
I have tried manually typing in my APN.
I have also tried network setting reset.
And finally, I have tried a factory data reset.
Running out of ideas of what else to try, hoping you guys have some ideas to help me out with this problem
Much thanks.
Flash a ROM and see if that does anything, if you want. Another thing to do is to do what the post below mind says, thanks.
Or join the Telegram Honor 7x group chat lol

This solution worked for me.
@firedeepinfire did you end up finding a solution to this issue? I am having the exact same problem and I have tried all of the troubleshooting you listed.
Thanks so much in advance!
I got a fix on it
Only one single step to do is
Go to Settings
Back up and reset
Reset
Reset network setting
This fixed my issue...
Cheers
My POCO F3 8GB/256GB suddenly not letting me call anyone (Says mobile network not available) or pick up any calls but mobile network and texting is working completely fine. I've rebooted the phone multiple times, disabled volte, reinstalled google carrier services and still nothing so I had no choice but to factory reset the phone but that didn't work too. Currently using MIUI 13.0.9 and hoping there's a way to fix this asap.

Use miui flash tool to reset your phone to he miui version it came from. If it does ot work then, it's a hardware problem.

I'll try doing the MIUI Flash method. I hope it's not a hardware problem because everything was working fine and I only realised few days ago it started to not work
Check with other sim. If problem remains check different network modes 2G/3G/LTE.

So I've tried using 2 different sim cards (One of them being the same carrier as the sim that's not letting me make or receive calls on the F3) and so far those sims are working fine with the phone . Also tried putting the not "working" sim on other devices and it seems to work fine so I'm not really sure what's the problem here. As soon as I put the sim card back on the F3 it works for a moment then completely stops letting me call and receive calls.
Try changing network modes.

That method also didn't work
did you try downgrading to 13.0.8.0 fw? could be a defective modem driver
Try manual network selection. If fails probably hardware.

I'm getting Location unavailable too on Firmware 13.0.9, revert back to Firmware 13.0.8, and the location is okay again. Maybe you can revert to Firmware 13.0.8, don't think too far first.
Try to enable volte and vowifi. I had the same problem to my device and it is working
