So my phone was in hard bricked state. I gave it to repair because I don't have access to PC. So after new official firmware I have very poor signal. During calls, the other side can't listen me after 3 seconds, or internet is very bad.
It isn't related to career, I have tried several sim cards. So I think maybe I have bad region radio. I have tried installing custom ROM like LinageOS, but I think it doesn't provide radio, so nothing is changed.
How can I debug this and find a solution. Still I don't have access to computer, but if you have any ideas I am here to listen. The phone is in Armenia if it depends.
If your signal oscillating during call this may be from antenna hardware issue!
Yeah, can be, just want to be sure it's not soft related. Is there a way that I can debug?
Or you have spyware on your phone.
Use 3G or 2G network and try it again!
Well nothing helps yet :/

Hi
Just got my new Samsung Galaxy Nexus today, but it cant find a network and have no signal.
I have tried to search for network in settings, but it comes up empty.
In the "about phone" page under signal it says -113db and 0 asu (varies a little bit, but not much)
I'm in Norway using OneCall, on the Telenor network, but the phone cant find any network.
The simcard works fine in other android devices.
The phone was sold as unlocked/simfree.
It says "onecall" on the bottom of the notification bar when I pull it down.
There are also apn settings for my simcard (looks like they are read from the simcard)
Wifi works great, and I can't see any other problems than that it cant find a network, but that is kind of a big problem since it is a phone!
I have rebooted multiple times, three factory resets, and tried with another simcard, but no luck.
Anyone have a idea what to try? should I try a custom rom? or do you think its a hardware problem?
I just saw "Telenor" when I searched for networks, but when I tried to connect it said it couldn't connect, and now I cant find it again.
Seems like I just have the worst possible antenna! (or radio?)
What type of phone did you have previously? Maybe you need an updated SIM card?
A new SIM card has solved this type of issue for quite a few people so give it a shot!

But it works in other phones like the HTC Desire and the old Hero.
I just drove into town, and I got a few bars, could make phone calls and so on.
But back home it still cant find a network.
Which leaves me to believe that the antenna (or the radio) is bad.
Do I have to root it and install a custom recovery to install the stock rom again?
Or is there a "rescue" solution? like on HTC devices.
Works fine here. Test a custom rom or another radio or something.. If it not works go back to stock and return it. I bought a HTC once with a bad antenna.
same problem
what did you end up doing kjetil84? I have the same problem. at home I have like no signal, but other places I have a litle. I use Talkmore witch also uses telenor.
an update would be great
That happened to me once before, try doing a factory reset.
still a problem
Just tried a factory reset, and it did not help
I love the phone, but at this time its not usable for me
SYMPTOM: can't see any mobile networks
BACKGROUND: I've been using htc one x for a month now. Initially on three, but their signal was unusable at home, so sim-unlocked and switched a couple of weeks ago to giffgaff ( a virtual network on top of the UK o2 network).
All has been fine, until today. I sent a few texts & calls in the morning, and mobile data was working. Since then, I can't see any mobile network.
wifi is fine.
Search Networks pops up "Error while searching for networks" and finds none.
No software changes of any sort since last successful call. No changes at all today, at least until I tried to diagnose the problem.
Running stock rom, with the WW update of a couple of weeks ago (1.28.771.9.CL56522 release-keys) -- neither S-OFF nor unlocked bootloader.
Nothing obvious to me in the normal or radio logcat logs.
The only thing I did after the last successful call was to run sensorly to try and map a trip. I've used this before without any problems. It got no connection but I thought nothing of that. I've since uninstalled it just in case it could somehow be interfering with the radio.
THINGS I'VE TRIED:
No, the airplane mode isn't on, and mobile is. I've toggled airplane from settings and power switch, many times
recreated the APN
checked other phones - yes there are a number of networks visible
tried the original o2 sim - same problem
safe mode
cold boot
reboot, reboot, reboot
obviously I haven't pulled the battery...
turned off wifi, in case it was somehow interfering
HTC diagnostic tool
factory reset
confirmed imei is not blocked
Any ideas? Bearing in mind that I'm looking for something which can happen spontaneously.
Interestingly, while writing this I've just noticed that Baseband version shows as Unknown. That worries me - is it possible that my radio partition has spontaneously corrupted itself?
I did speak to 02 support - they said to take it into a shop for warranty repair. I don't want to try a custom ROM just yet -- not when I might have to use the warranty. But is there any way to force it to reinstall the stock rom (preferably not involving windows)?
I have the same problem as well and flashing custom roms did not solve it for me. But for me even the IMEI number is shown as UNKNOWN...I haven't done anything special to get this issue, one day when I woke up the phone could not connect to any network.
I have tried a lot of different methods but with no success. I don't think we can do anything about the baseband without S-OFF.
If a hard reset fails, then it's time to think about returning the unit. Either get a refund or get it replaced.
This may be irrelevant; but I've had this happen to me on my GNexus. I solved it by going back to stock and it just fixed itself overnight.....
my HTC One X did the same after about 2 weeks. Gave it back to supplier, waiting my replacement.
Even tested with a different SIM card, did a hard reset. Problem stayed the same.
Im curious did any of you find a resolution to this? it happened to me a while ago but yet to fing a solution. HTC refuse to fix under warranty because it is unlocked.. i am currently waiting for the next official update to see if that fixes anything but the way things are looking that could be a while..

It sounds like a fault, probably the radio chip has just stopped working, no software is going to repair that. If it was a software problem, there would be hundreds or thousands of people all having the same issue.

Device: European GSM model "YAKJU"
ROM: stock 4.2.1, freshly installed from Google provided image
I swiped my device a few weeks back, after a bad experiment. Reflashed the Google image and all was swell. Until a few days back, my phones radio seems to crash at arbitrary moments, yet very often.
Symptoms: good reception, able to use internet over EDGE/3G and all of a sudden no coverage whatsoever. Nothing then works: tried going into airplane mode and back, tried resetting the radio in the telephone info menu (*#*#4636#*#*), the only solution is to reboot the phone. Then we're back to square one: everything works for a short while (minutes at best) then zilch again. Very frustrating!
The funny thing is, the telephone info menu still gives me info about signal strength. Also, IMEI number is no problem, I still have one (seeing this seems to be a common issue).
I'm completely lost here. Why would my phone, all of a sudden, be doing this? Anyone? :-\ Is there a logfile somewhere I could look at (rooted phone), possibly telling me what's crashing exactly?
UPDATE: well, I thought swapping sims with a colleague would be a good idea to troubleshoot further (and make sure it wasn't a faulty sim card), but to my horror I now get no service whatsoever, even after a reboot! The phone doesn't even ask for a sim code... Yikes? Hardware failure or still possibly software? Would a factory reset do anything?
UPDATE2: Factory reset didn't help, at all. Same issue, no connection whatsoever.
UPDATE3: What the ****ing ****. I reflashed the stock Google image (again) and at first it seemed much worse: I no longer had a IMEI (*#06#). Hit the Google and saw nothing more than "ahh, sucks, send it for repair!". So I was preparing to do so, took out the battery to write down the serial, popped it back in, rebooted and... all is well now. IMEI is back and it seems to have and keep its connection now?! I don't have a single clue on as what and/or how though, but it sure as hell is no hardware issue. Google, get that **** together, this was your flagship phone! :\
UPDATE4: Spoke too soon. Scratch the previous update, I just lost all radio again. Back to square one!
Noone?
Hi all,
having had the malware come through in the recent OTA update, I decided to do a factory reset to get all my data off quickly before any of it went to someone it shouldn't. Before the OTA the phone was working perfectly!
Unfortunately, after that, I have not been able to get connected to 3 Mobile (UK) although it worked before. I get the "Can't connect to this network right now. Try again later." message.
I've flashed a variety of ROMS, from old stock, to new stock, to Eragon.....none of which allow me to get on my network.
Wifi works fine.
The IMEI did disappear, but I was able to follow instructions online and manually reinsert them successfully.
I wonder if I have somehow knocked out the RF frequencies as I did not know I needed to make a backup of these.
ANY help you can give me to rescue what is a pretty decent phone (let down by Elephone's software!) would be great.
Thanks!
I have never had this problem thankfully so I am not sure what you should do but the video in the link below may help?
https://www.youtube.com/watch?v=qnJr7RQa2Kk
Some progress - oddly enough I tried restoring the IMEI numbers to the opposite SIM sockets and now the RADIO setting declares that it is on.
I think this is because it is a very early version of the phone and perhaps the SIM labelling was the wrong way round. Who knows.
I've attached some screenshots of what seems to be going on right now. Any ideas? Anyone?
I can get the phone to connect to 4g, but it will not connect to 3g/2g.
What do I do now?

Glad you have managed to sort of sort it. For 3g have you selected that in mobile data settings?
It was a hardware issue - opened the phone up and the antenna connector had come away from the motherboard. Must have happened when in my missus' handbag (her phone - not mine!).
All solved now.
Might be worth others checking their antenna if having the same issues. Under the plastic cover is a little rubber 'knob' which puts pressure on the connection. I don't think the back was screwed down hard enough to keep the correct pressure on the connector.
Hi..
I have a Zenfone 5Z, bought on GearBest, so yesterday it updated to the latest WW version o it's on. After updating it lost the Network Signal, even after a several restarts. I've downgraded it to WW__ZS620KL_80.10.8.54_MP_user_20180517175955 , but still no network signal.
I've tested my simcard in other phones, other simcards in my phone, but still nothing. When i try manual network seach, it gives an error, and when i select automatic network, it says that is already registered to network, and when i try to make a call, it says me to turn off airplane mode to make a call. Also when i remove and reinsert the simcard it recognizes it a makeme chose betwen sim 1 and 2.
I've attached few screenshots too.
Pleaase help me guys!
P.S. i gave this phone to my wife on her birthday, now, she is mad with me!
HI,
I had this same issue, later i checked up with service center, they told charging pcb(which contains antenna lines) was water damaged.
Then got replaced the part and started working again.

Yes, but after an update you lost network signal?
My phone never got wet, and never fell down.
Thanks!

Hi, Yes, even I had not let my phone get wet or dropped but phone is so worst when it comes to water resistance.
Smallest moisture in hands while using the phone is enough to spoil the PCB.

I have the similar issue.Is it resolved for you ?

Nop, i had to send the phone to Asus authorized service center, they changed the SUB PBA...
I works for exact 30 days and, after a restart becouse the system crashed, it has no network again!
so i sent it to serce center again today...
As I don't see a reply stating how it got resolved, I will post my experience of this issue. Firstly, this issue is fairly common with Huawei 5Z. The reason given by local service team here is at times if the phone experiences some jerk the contact from antenna to motherboard breaks. At times it could still remain connected in which cases person may get signal some time and get airplane mode at others, in many cases airplane mode is ON permanently. Apparently they have some kind of a glue with which they can attach the antenna permanently. Once I got it done, the problem has not resurfaced.
P.S. this problem has got nothing to do with software, so restart, factory reset etc. will not work, nor does it happen with software upgrades. It is purely mechanical in nature and does not need even require a drop. but the solution is quite simple provided the service centre team knows. In case they don't just ask them to stick the antenna connector with a proper glue and it should be sorted.
What am I supposed to do with my set. I imported it to my country and can't find a service center anywhere in my country. Apparently I can't find any solution online so I am out of luck. If there is anyway I can fix it, or anyone could share what should be replaced will be immensely helpful.
Need your help guys.

Based upon above comment if the root cause is same as described i.e. connection b/w motherboard and antenna bands is broken then you can watch teardown video on YouTube for 5z by wit rigs. It shows how you can disassemble each part of the device for repair.
Apparently you will need to have some expertise and tools available to perform the task yourself. Better work with some local mobile repair workshop and explain them by showing video and above comment.
i am currently using 5z and i can says its due to updates especially from oreo to pie ( yes this problem is originated from that update). Its a software problem and they cannot solve the bug till now. There are still lots of 5Z with this issue pop up every week. The solution is to send to service centre to replace the motherboard and pray it wont happened again. This is my second time sending my phone there for the same issue. The antenna or motherboard dont simply fry or disconnect after an updates thats for sure.
Randomly changing different sim cards in the sim slots along with fiddling with the mobile data setting that comes when you insert the sim card tray worked for me, it worked for someone in zenfone forum also. Give a try and let everyone know..
Same here, after update signal lost... damn ASUS
My network signal stopped out of the blue and not after an update.
I tried changing sim cards in a lot of different combinations, but nothing worked, but the phone always found the sim cards.
I disassembled the phone, removed the antenna cable and attached it again and now the network signal is back again.
I had same problem. After the latest update, Everything working fine untill one day i restarted my mobile. Damn.. After reboot, the signal disappeared and can see 'x' at signal bar. I have rebooted many times but of no luck. Then i removed the sim tray , swapped the sims and then the signal starts showing. Initially after the update, one time I faced same issue but that got cleared after I disabled and enabled the sim in "Sim Card Information". The only issue i a, facing is the signal drops for every few minutes or hours and comes back automatically. That's what making me to replace my phone other than ASUS. Does anybody have a solution for this issue?
Update :
My phone had a sudden reboot and since then there is no network. Showing no service even if i swapped sims and re inserted. frustrated with ASUS

No. In my case/In most of the cases, its not the harware issue. initially i thought the same. But later found that only after updating to the latest update i faced network loss issue. sim not used to detect even after taking the sim tray out, shuffling with sims. I downgraded the firmware to previous version and then immediately i could see full network signal. So the issue is only with the latest, not with the hardware. Just give a try and confirm..
The same i have mentioned in that post also. Just give a try and update. Definitely that will work

So I can do the same as you: downgrade to get fine.
But how to still updated firmware and keep the signal?

The only solution is to walk to the nearest service center and make the antenna fixed. I have given my phone to the authorised service center and they resolved the issue by applying glue to antenna (they told same). They charged for the diagnosis as well as for glue. They guaranteed that the issue wont repeat. But i hated the service by ASUS and planning to go for samsung or Oneplus.. My suggestion is go to service center to get it fixed
For all of you still facing the issue, the solution is extremely simple. And yes it is purely mechanical in nature just like someone mentioned too. I just wrote a post regarding this. Check it out.

It does not even require to take the phone apart.
