network problem - Zuk Z1 Q&A, Help & Troubleshooting

Hi guys,
Now my zuk is unable to connect to any mobile network.
The problem isn't new, two days ago that was happened becouse I change the bands from the test mode.
But the strange things is that i solved it restoring the system partition by a nandroid backup, but now the same backup didn't solve the problem.
I'm sure that the problem is about the bands becouse I can see only a operator that use a different band and also from the test mode I can choose some network but not all.
Another strange thing is that the second time the problem occurred after a simple reboot...
Thanks for the help

I have the same problem and there is an older thread covering this where 2 other people also have the issue.
The only fix I found is to power off the phone. When restarting the issue is cleared.
As an aside I notice that to diagnose that the problem has occurred you can try to change the "preferred network type" and see that there is no pause while the phone works to switch from 3G to 4G or whatever. Normally there should be a pause of a few seconds whilst the phone switches over. When trying this and noticing that the phone appears to do nothing at this point (by which I mean there is no pause and nothing much happens) then I know something has fallen over and that I have to power off the phone.
This is obviously a software problem and, like most bits of technology in our lives, you just have to switch the thing off and on again to fix it.
Lets hope the promised upgrade to Marshmallow next month fixes it.

All got that problem on COS 12.1 use custom firmware.

Please do not generalize like all on COS 12.1 have this problem...my phone is complete stock on COS 12.1 and I have NO network problems since day 1 (more than a year my daily driver). I have been travelling the world using my phones dual Sim function to the fullest and never ran into problems. Maybe I have the only good working ZUK1 on the whole planet but then again I don't **** around with the frequency bands nor did I try to unlock and or root my phone...

Hey buddy, Could you please lemme know the version of COS 12.1 that you are using.? I am running on the stock version updated to 12.1-YOG4PAS7DF. Being frank, I am not totally satisfied with the network coverage of my phone. My earlier phones used to work flawlessly at my apartment and since I switched to ZUK, I am facing network coverage issues and data connectivity issues with the Same operator. Are you mostly connected to LTE network.?

12.1-YOG4PAS9IG. While home I am on WIFI and while away from home I am on LTE or whatever the reception allows depending upon my location. I do live in a remote part from France so I do face network coverage problems but at the same time it does not surprise me.
It could be well that the ZUK1's reception is less than other models or brands or even other ZUK1's something I have not confirmed. All I can say is that I am happy with the phone performance.

Happened 9 days ago, after a day it resolved itself after restarting (nothing happened by restarting, changing roms, restoring factory backup & so before).
Again happened & didn't resolve for a week+. was going to get a new cell today but last night it resolved itself when I rebooted to recovery to install a rom, but changed my mind for then as I needed flash light, rebooted system & signals were there.
It happens & goes away.

Data keeps randomly disconnecting; radio update needed??

It's been happening for a while now. I can have full signal on H, then suddenly no H, E, or G. Data does not reconnect automatically; I have to force it by switching Airplane mode On/Off. I saw something in the forums about a radio update, but I heard that removes ability to change permroot/S-OFF. Please help me clarify this, and if there is an update, is it safe and should I install it.
Stock ROM, temp-rooted with Visionary and permrooted with HBOOT/WPTHIS_OTA method. Kernel is the one linked in my signature thing [1497KHz] and pushed Wi-Fi module. Hopefully that's enough info. Let me know if you need my SSN# ...lol

Don't see how that correlates with my problem? Still or moving, it happens randomly.

I have been experiencing this exact problem quite often over the last two weeks. I am using CM 6.1.1 in Chicago.
same situation happens to me...nvr seem to have a solid 3g/H in my house. While my blackberry will be having 3G all day. The g2 will fluctuates from H -> G -> E and stays like that. So annoying that ruins the experience of having a good data phone.
Same problem here! It happens from time to time, I have to switch off/on data to get reconnected.
Also happens when I turn off wifi after a long period of use, It won't reconnect to the carrier's data.
I had this when I switched over to CM 6.1.1. I thought it was CM so I flashed my backup, then decided to try it again. The problem I found was Pershoot's kernel. My data connection would drop and come up on it's own and was happening while I was using data. I've been running CM 6.1.1 with it's kernel and haven't had this problem since.
Same here running latest Virt (tmous g2) and I *think* it's running a pershoot hybrid.
I have never run Pershoot's kernel, and have always used the kernel included with CM. It seems to be recent (last two weeks) problem for me. The phone cycles from 3G->G->E->3G->H. The worst, however, is when it shows 3G->H but cannot connect to anything. The only solution is to turn off the data and let it reconnect.
I think it might actually be network related and not hardware / software. Maybe too many new phones activated around the Holidays? The reason I think this is that my Nexus One keeps having similar problems --- even on different ROMs.
Could be either?
I used to be on Mobilicity in Canada and experienced this (random disconnects from data several times a day, wouldn't automatically reconnect), switched to Wind and I haven't had this problem.

Data Problems...
Ignore my signature I'm currently on G2.
I think the problem you all have might be a TMobile problem.
I live in Madison TN / Nashville TN and I been having that data drop problem for going on a year now. Happended on every phone I been on Mytouch 3G Mytouch Slide Samsung Vibrant HD2 and now I'm on the G2 that I bought yesterday. Also had the same problem on a Nexus one.
The situation was that I will have all my bars and a 3G/H symbole and my connection would just fall a sleep with the 3G still in corner. Put phone in airplane mode and take it out airplane mode and my downloads will resume.
This process would happen after 15 min or 20 min of constant data.
2 days ago I started calling tmobile to get this fixed. Told them I didn't have this problem on ATT and Verizon so they put in a service ticket with the engineers and they claim it should be resolved in the next couple days if mot to give them a call back and to forward my call straight to level 2 tech support.
More people should complain about it.
That happended across atleast 5 different pda phones and 3 different sim cards. Yeah some of the phones had custom roms but each phone shouldn't have the same symptons.
The cellular towers in my area must really have a problem and I'm expecting a credit on my account lol.
PS connection is perfect on Edge though... Just slow...
Could it be because of overclock?? What if a certain CPU speed doesn't play well with the radio?? Just a thought...

For that to happen to me on 5 different devices that will tell you that CPU speed has nothing to do with it. Best I can say is to reset your phone to stock and give TMobile a call and let them know the situation. If you dont, nothing will be done about it.
I say to return to stock because if you dont, there reps will try there best to put the blame on you and the custom software. But from my experience being on Nexus One / MyTouch Slide / MyTouch 3G / Samsung Vibrant / HD2 / G2 all having the same exact problem????
Yeah the problem is on TMobile end...

Is it the same EXACT problem I'm describing? Or are you talking about general reception? Because some people on here with different ROMs (or radios) have mixed results. I'm in an HSPA+ area with full signal usually, but I keep having my data disconnecting. After a while it comes back, but I don't like to wait that long. I just switch radio on/off. :/

Yeah it sounds like the same exact problem to me which I had on all those other phones too. Im like you I dont feel like waiting so I switch to airplane mode on and off and the data comes back.
Or Il just drop to 2G Edge only and the connection is stable just slow though.
I couldnt find a solution online so now I got tmobile reps in the picture to get this resolved for my area though.
Count me in. I HAD a BB 9700 and it behaved the same way you guys are talking about but i didn't have to set it to airplane mode to reset the connection. I do however have to restart my G2 sometimes to get it connects to Tmobile network again. It is such an inconvenience.
I'm on stock rooted rom by fastludeh.

Yeah TMobile need to get this fixed. I plan on giving them a call back on Monday or Tuesday since my 3G connection still continues to drop.
Im currently on ALL stock on the G2. Havnt did any modifications yet.
Would changing the radio help? i see there is other radio firmware available...not sure if that will do anything for our phones. Currently sticking to my 9700 for now until this issue is fixed or if i get bored of the 9700 and jump back to the G2

Na I dont think changing radio will work. I tried multiple radios and custom roms on the HD2 and same situation over and over.
Having problems with everything connection on my g2 it started happening like two weeks ago. Random no service for like a minute then full bars and hspa never use to do it but now it does frustrating as heck oh on a stock froyo too wtf

loss of signal

Hi everyone,
my xperia arc lt15a has a problem since a week or so. I'm very concerned.
Everytime i shut the screen off, when i go to turn it back on, i see for a millisecond that on the top says emergency only, meaning that when the screen is off loses signal. Once i turn the screen on it gets the signal again. At the beginning it happened when i had it for long time in my pockets, but now its getting serious. It has US generic firm 4.0.2.A.0.42
Me too!.... Maybe its a firmware issue???
and if i go into About>battery use> graph.. it is mostly RED meaning NO SIGNAL over 60%
There is this problem going on with -56 baseband (which is present in the .283 and .42 firmware). Hopefully SE fix it fast...really fast.
oh thank god its not a hardware problem...anyway its very serious: this means that all the times the phone is on standby we loose messages and phone calls since it doesnt get signal!

Yep, it's a serious problem. Not only the one you mentioned, it is also leading to battery drain and the purpose of this device as a mobile phone is being defeated.
i can't belive sony ericsson is not taking care of it. i'm going to send an email to the support.
i have the same issue in miui rom
hey guys please tell me its not a hardware too, when I was on .368 with locked bootloader, it was normal, but after unlocking bootloader, and testing many roms, all roms, my wifi connect, but after few minutes, even it is connected, the internet become inexistent, everything that needs internet does not work, market says No connection, browser does not open pages, msn does not connect and so on. If I put wifi off, and on again, everything goes normal, but few minutes, like 5 or 10, it happens again, stay connect but no internet... some help please? Thnx anyway

This is serious but I must say I have not noticed this as a common problem.
Have you guys tried to reinstall/repair the phone software via either SEUS or PC Companion? If not please do and check if the problem remains.
If it does check if another SIM card makes any difference.
Keep me updated.
Its a sotfware problem , i haver .42 , in spain , and i`m having the same problem since .42 .
Wow, never would've noticed this if I hadn't come here. I have the same problem, LT15a with .42 in USA
Did anyone of you not have this problem before updating to .42? Has anything you've tried since you installed .42 helped (e.g. new sim card, sw repair etc.)?
We are rolling out the .58 software on some markets as I write this. Other markets will follow.
(I don't know which ones that have received it already or when it will come to a certain market.)
As soon as someone here with this problem gets this update, please let me know if this solved the problem or not.
If this is a bug in the .42 it will hopefully be fixed in this software.

I was using Singapore .145 firmware and didn't have any issues with reception, but since the day I upgraded to .42 the reception issue is there. Nothing could get rid of this issue and I noticed that it started with .283 itself.
Currently I'm using older baseband (-36 from .368 firmware) with the new firmware .42 and it's fantastic and stable without that buggy reception problem.
Note: Honestly I don't know whether you are really from SEAnswers, but I'm replying in a hope to get this fixed .
I know many arc in spain with the same problem .... so ...
Same reception problem
I have the same reception problem in Morocco since last update, sometimes i need to disable WCDMA in network options to solve the issue
yeah, i had one night this issue, 70% of battery drained to 5-6% wlan on, sync on. i think 7-8 hours.
and this day, 40 mins internet on with sync, mp3 1 hr headphone.
and batt. temperature 40°C and phone was hot.
10 min display on. and i havent run any app except fb and browser.
Try .368
I had this on both .42 and .58. Reception was terrible.
Have "down-graded" to .368 and I have perfect reception everywhere.
Whereas before I'd stopped using my phone for anything that required Data. Now am bock on Facebook and Twitter with avengance!
Its like a new phone.
Hope this helps others...
I have made a small patch for properly using baseband -36 in other firmwares.
Check it out.

[Q] Wifi Issue with LG-D802. Advice is very appreciated

[Q] Wifi Issue with LG-D802
Hi all
Few days ago i receive my G2 and quickly updated to android Kitkat (Never experiencing Jellybean on this phone before),
I started to have some issues with the wifi. The wifi appears to be connected but sometimes there is no data transfer and wifi automatically disconnect even in the strongest signal area (the router is just below my desk of my phone) and the wifi settings was still turned on.
This occurs with every router from normal to the strongest connection.
Besides the connection drops also occurs on this phone which there is no internet connection even when the wifi is connected
So is this the wireless hardware issue or anyone experienced this before? Would like some suggestion please, Thanks!
So... just to make sure, you are running the default/stock ROM with OTA update to Android KitKat right? I am currently running CM11 nightly, and sometimes it has issues with connectivity (wifi/LTE). Let me know.

Yes it is running stock LG rom at 4.4.2
Here is what i would try:
1. Try resetting the phone to see if the errors go away. Maybe something went wrong while upgrading
2. If the problem still persists, and you are expert at ROMing - try installing a different ROM to see if this is related to LG's ROM.
3. Get a replacement if under warranty.
Just to let you know, KitKat does have some wifi issues. Some people are reporting issues with 4.4.2 and not with 4.2.2.
Hope that helps.

I have reset the phone after i face the problem after the first day of use. However it does still appear but not in a very frequent like minute or hour basis. The connection drop and wifi disconnects occurs randomly during normal browsing/playstore/ social apps activities. I guess it was very hard to get for replacement under warranty if the problem was not really significant (occurs 2-4 times per day) although it is still under warranty coverage.
Thanks for your advice, i am currently looking towards in accessing device debug log to try to proof them there is something wrong with the wifi on the phone.
For me the same problem happened and i found out the solution by lowering the band of rounter to 54mbps only

Random signal loss

Hi everybody
I wan to ask, if anyone has a similar problem or a solution.
Me and my girlfriend bought a moto x play for its dual sim ability.
We experience random signal loss several times per day. Its just falls off for few seconds, sometimes longer without any reason. Then i have to turn airplane mode on/off, to manage it. Its pretty annoying. I had the same problem with last years moto g2. The sim card, that is dropping signal is the one i use mainly and preffered for data.
Just to mention, that i was using my simcards about a half year in my honor 6 plus dual sim and i never experienced this. Sot the troubke must be in the phone.
Is there somebody who has a fix for this?
Thx
Peter
hi i have the same problem. i am here in germany with base (hope u know what i mean) in my second simslot i get a o2 card. now its strange. always that slot with base sim have that problem. i tried it with a lot other base sims from friends etc. always same result. without reason (i have luck) 1 - 3 times no signal for few seconds. on other fon with base that i take with me to check if it also have no signal but there always ok (testet it also with my card in other phones the card is 100% ok). hope u have a fix. and by the way sorry for this ugly and bad english. i can read good but write is not mine. thx everybody

possible solution
Thanks for your answers.
I did contact motorola with the problem.
They adviced me to run the phone in safe mode (only preinstalled apps, nothing from my downloaded apps are in this mode) and step by step (can take a days) to add my apps and see, whic one does it.
The safe mode did ok ( no signall loss) but then i just booted in normal and uninstalled my apps. (since i dont use so much of them) whats important to know, that my wife has the same phone (same issue) so i can compare it better.
So i realized, that it could be the app CAM SCANNER (app, which makes pdf from photos, APP FROM innstig COMPANY) I stopped using this app. I tought, that the problem is gone, but now still, the random signall loss happens much less, bu it still happens. If I have more time to play with it, i will try to delete some other apps.
For the moment its not so bad like before. i have, lets say 3-4 random signal losses per day. for me its strange, that an app can cause this. and i hope i dont have to uninstall apps like dropbox, or something i cannot live without. I blame motorola for thi, because this was a problem allready with lastyears moto G. ( my previous phone was honor 6 plus dual sim, these things never happen, and i used the same apps. Of course i changed the phone, because the OS was horrible on it (emui...))
So im still trying, if somebody has a possible solution, please post it. Im also thinking, as the last option, to flash cyanogenmod. Its allready an unofficial version, i hope it becomes official soon.

As squid told that he has moved on to cm13 and he will push to make cm13 as official, cm12 is already there. Also soak test has begun. Its just matter of some few weeks before the official update from Motorola lands on x play.
Marshmallow update
Hi everybody.
I allready recieved the marshmallow update for the moto x play dual sim. Nothing changed. Same results by my wifes phone. The signal is falling out randomly through the whole day. This is really bad.
I had this allready with last years moto g 2014 dual sim.
Im giving up. I don tgink i will get another motorola this year.
Did you try changing preferred network data to 2G or 3G? (Wireless & Networks > More > Mobile networks > Preferred network type)
If it's on 4G, it's most likely that signal is too weak for 4G in some places. Network type (2G,3G,4G) affects the signal and battery drain if signal is too weak even if you're not using mobile data.
If that doesn't help, then I have no idea.
Hi All,
I had this problem. The phone would show "No Signal" even when others on the same network were getting a signal in the same place. Plus the SIM would work on another phone. The mobile would be off the signal for hours and then connect for a few hours. I tried everything that is recommended including a factory reset. No resolution.
But I did notice that if I charged the device the signal would come back for a while.
So, being a complete novice at this, I did what I thought best. Went into battery saving and switched everything off battery saving. ( Switched everything off because I do not know better )
Since then the mobile has been connected to the network 24X7. I use mostly 3G as my preferred connection choice. The phone does switch between 2G and 3G depending on signal strength I guess.
Hope this may help someone. It is not an educated fix, but seems to have worked with me.
Incidentally, Motorola had suggested that I take in the phone for servicing when I contacted them. As that is a long journey, I tried this fix as a last resort - and it worked for me.
Cheers!

Nexus 6p constantly dropping signals

Hi,
I have seen some posts here with lost cell connectivity. However my issue is slightly different and started to appear few weeks back. I was rooted running stock 7.1.1 OS with Franco kernel. My phone started to loose signal all the time. You can just look at the signal bar and see the signal strength going all the way from 100% to 0% in every few seconds. I have tried different radio versions, new ROMs, restoring my Nandroid backup etc. Nothing seems to work. Changing to 3g shows the same issue and I have no signal on 2g only mode. I am in AT&T.
Also wanted to add that I can make out going calls from my phone. The issue is when its idle. I don't get any incoming calls due to this issue.
Any help will be highly appreciated. Currently using my office iPhone and feels terrible.

I'd run up to AT&T and ask for a new SIM. It's free and you rule out something on their end, and the SIM too when they provision it. Is your phone carrier (SIM) locked to AT&T? If so, I'd see about getting it unlocked so you can test other carriers. If already carrier unlocked have you tried borrowing a friends SIM on another network? If signal continues to drop it could be a hardware issue.

I have tried with another sim. The issue still persist. Also I have tried my sim on a new device and it seems to work fine. So I am almost certain that the issue is with my phone. All I wonder is whether its hardware or software.

You sound proficient enough with flashing ROMS, radios, restoring Nandroids to know this already.... you are probably just postponing the inevitable: Back up and pull off all your data, format the partitions, and flash the latest full factory image from your PC using flash-all.bat. You will have your answer very quickly- in fact you will know even before you begin to set up your phone. If you are still under warranty this will be step number one with Google or Huawei.

My Nandroid backup was actually a vanilla 7.0 image. I will give this a try with the flash-all.bat and update here
Any update?
