Okay so I just tried updating manually to Pie using the zip file from this thread: https://forum.xda-developers.com/zenfone-5z/how-to/zs620kl-fota-update-links-update-20-08-t3831794
Here's where the problem starts. I placed the zip file into my internal storage and rebooted. Sure enough, I got the update message but when I clicked it, it said: "System update failed".
From this point onwards, my phone shows "no service" even when it is able to detect the SIM card. I've put the SIM card in another phone, and it works without any problems. I find this weird because if the update failed, why did it affect the network connectivity?
I tried the following, to no avail:
turning on and back off airplane mode
factory reset
in mobile network settings, I tried manually selecting the network. When I try, it says "No networks found"
dialling *#*#4636#*#* -> Phone information -> "Mobile Radio Power" -> I tried to switch this on but whenever I leave the screen, it goes back off automatically
IMEI number exists. No problems here.
So I used a suggestion from the comments and wiped data and cache from FOTA Service and System Updater, and tried the update. It worked. I'm now on Android 9, still with "no service" error.
I've been trying suggestions all day and it's leading me nowhere. Really frustrating. I'd be thankful if someone can offer some helpful suggestions.
EDIT: It turned out to be a hardware issue. What are the odds? Maybe the software update caused it, idk. Repair guy said something was loose inside, he fixed it within 10 mins. If you guys face the same problem, get it checked with your local Asus authorized service center. Warranty covers everything.
Download the update for asus's website it's about 1.65gb. it would work
You mean the latest Pie update? On the website, it's for Taiwan SKU only. It won't work.

Yes, I was able to upgrade to the Android 9 ROM. That's not the problem. My problem is having no network connectivity whatsoever. As I said, "no service". Persists even after downgrade. I think it might be a hardware issue.

Please read everything properly. Please. The link I shared has two guides separately- one for rooting and one for downgrading. You can downgrade without rooting. Also, the link you provided is strictly upgrading only. Stop wasting everyone's time.
Hi...
I had the same issue 2 times!
First one was after an update, my phone restarted, then "no service" after that! I tried to downgrade, tried to reset it, and no service...
So i sent my 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 again1
so i sent it to serce center again today...
I updated to Pie on 28-Jan it was stable for 4 days on 3rd feb. It is showing 'no service' i reset the phone but no use. Any please help......

If you've exhausted all your options software-wise, then it's probably a hardware issue. Check it out with an Asus service centre.
Hello everyone! I figured out the issue and the solution to the dreaded no network/no SIM card issue for the ZenFone 5Z. It is not a software problem. It is a hardware problem indeed. The new firmware basically lets the SIM card slot "work properly". If the SIM slot of your phone is defective, this issue will trigger after Pie update.
Why it is happening:
Take a look at the image below (courtesy FCCID.io)
There is a switch (highlighted in red) which "tells" the phone whether a SIM is inserted. When the switch is closed, it means no SIM card is installed. When the switch is opened, it means SIM card is installed. If you insert the SIM tray, it will allow one of the metal to lose contact with the other hence telling the phone to operate SIM signals.
If the top metal cover is pushed down and touches the switch, this SIM enable signal will malfunction causing the issue you all are facing.
Another close up photo (courtesy: FCCID.io)
The solution:
You will need: A SIM ejector tool for removal of the SIM tray, a flashlight and a precision knife (I used a surgical knife since it is thin and rigid and works perfect).
Turn on the flashlight and look at the SIM slot from the side. You will be able to see the switch terminals I am talking about from a different angle. It will be the farthest terminals just a little bit to the left from the mid point. Insert the knife and tilt it very gently keeping your hands steady such that the top metal lifts slightly from the switch contacts. If careful, you will hear a click. Insert SIM and install SIM tray. Cross your fingers and behold! You will get network. I am fairly certain this is going to solve your issue. So if your phone is out of warranty or you don't want to avail warranty for such a silly issue, give this a shot and post whether it worked for you.
You can also check the teardown of the phone at FCCID.io. Key in the FCC ID of ZenFone 5Z - MSQZ01RD.

I flashed in JB AOKP was working fine all of last night. I also entered my SIM Pin or unlock code. The first time I put in an 8 digit unlock code I have. Second time it prompted me I skipped it. I'm pretty sure it was the security pin and not the network unlock. I don't have any other phone's micro SIM I can insert into my phone and a local phone store's T Mobile SIM produced no different of a result except for replacing AT&T with T-Mobile (I have not however put my microSIM into another phone...because I don't have another micro sim phone). Reboot phone this morning and it's no longer working. Tried to enable 2g. Nothing. Tried a battery pull with the phone on, pulling the SIM (same message with SIM pulled out),
Wifi works
This sucks big time ;(
Note: I am pretty sure I did not network lock the phone or anything because the SIM prompt that came up when I flashed JB did not ask me for my unlock or network code (I would have known). The first time I entered that code was 'just in case it's asking me to unlock" but why would it ask me a second time then? So I doubt it was prompting me for a network unlock code. The prompt from youtube videos was different too.
Also APN is empty, but I think that's becasue I'm not connected to any network
Pressing Available networks brings up AT&T AT&T AT&T T-Mobile T-Mobile "311660" pressing any of them you get a quick window connect "too fast" goes back to/stays in available networks screen and says "Can't connect to this network right now. Try again later."
So I added the AOKP and Corresponding kernel yesterday and I mean it was working fine with 4g... apparently this thread says that you need to flash a new radio in some cases when you change kernels?

...what are you talking about. My IMEI isn't mentioned once in that post. In fact now that you mention it, since people's IMEI changed...nothing like that my phone still has its IMEI
I also did not get a "phone frozen" from entering the wrong code too many times...so I doubt its locked like that. There was a random reboot that I WOKE UP to, but nothing weird...it rebooted randomly but worked finely after that

I was proposing the theory that you may have lost your IMEI, since the symptoms you report were very similar to what I was experiencing when I lost mine, however since you still have yours, must be something else, eh?

Well, mine was definitely due to a lost imei that happened sometime when flashing.
I did get the network unlock warning thingy twice, and then had no cellular connectivity, which is why I mentioned the lost imei. I restored my nandroid back to stock, then used the method here with a little driver tapdancing to reinject my imei, and that solved my issues, but sounds like you have something else going on.
http://forum.xda-developers.com/showthread.php?t=1801997
If I flash back to stock and no longer have the stock kernel, what is the steps for flashing back then?
1. flash stock kernel
2 fix partitions
3. factory rest/cache/davlik
reboot into oden and flash new image?
Long story short, Don't cut your own microsd..the sim pins on this phone are VERY sensitive and hard to fix/see. Don't bend em.
I am having the same problems right now, I keep on getting " NO SERVICE" - SELECTED NETWORK UNAVAILABLE" Error.
Rebooting doesnt help, flashing modem through CWM doesnt help. I know for a fact that the simcard it good because other apps that I install can read the sim with no problem, and my WIFI is working like a charm.
Someone got a solution for this? This is already like 4 days ongoing, please any help will be appreciated !!
Im having the same no service selected network issue. I can search and find att and the mobile but when I try to have it connect to att that's the error I get. I have an att SIM card in the phone. Sph l720 SIM unlocked, it didn't ask me for an unlock code or anything like that but I also don't get the invalid SIM card error. I've added the main apn from the att website but that doesn't help and the phone is current set to gsm/umts. If anyone has a fix please let me know, thank you.
So stupid me was fooling around in the *#197328604# menu and I accidentally screwed up my IMEI number (whoops my bad. not going in there again). After watching a YouTube video (Found via Googling), I managed to restore it (It now once again matches the IMEI on the bottom of the phone's box). However, I still have no cell service.
1. When I have the phone on the lock screen, it says "Emergency Calls Only". From time to time it may also say "Invalid SIM" or something along those lines.
2. When I look for mobile services (Settings -> More Settings -> Mobile Networks), it pops up an error, "Insert SIM card to access network services", even though the SIM card is inserted.
3. Sending a text message fails. It just says it will wait with it until a network is available.
4. Placing phone calls fail. "Not registered on network"
5. The phone can read the SIM though. Going to the Contacts, and going to Import/Export has the SIM card options, and nothing goes wrong when selecting them.
Where can I go from here? I've cleared the Dalvik Cache to no avail as well. It almost works, so I think it's software related, or perhaps my SIM is malfunctioning, but I want to exhaust every possibility before going back and saying "my phone is acting wonky".
Have you tried a factory reset? If that fails, you might need to reflash the ROM.

Yeah. Resetting it failed. I can't get past the setup. After skipping WiFi setup, I just get a black screen and nothing shows. I may have to do a stock reflash. If that too fails, I may see if I can bring it in.
Edit: Stock reflash failed to fix it as well. Gonna bring it back and get it replaced.
Edit 2: Got a replacement SIM, didn't fix the problem. Seems it's hardware based (or software). Is it possible to remove all traces of a root before sending it in to make it appear unmodified?

I've recovered from doing the exact same thing. It will take a lot of trial and error. What network are you on?
hi
I have a very annoying problem whit the sim slot 1 (i currently test the slot 2)
Very often, the phone tell me "Sim card not detected", and i have to open the phone, dismount the card and put in again.. until the next time.. like i said, it's occurs very often, 10-15 a day..
Even when the phone is on the table without touching it..
I have rooting it and thats it.. 2.19.40.22
I would like to know if someone have similar problems before i try to reflash whit older stock rom??!
It happened to me briefly- After flashing my first full back -up back to the fone --then i did a factory reset and this fixed the sim slot problem

Thanks
Above, I was referring to the full 5gb asus ROM back up I made immediately after unlocking bootloader installing twrp and rooting, I installed svn ROM and backed that up too..stripped svn ROM further..backed that up too. Then went about trying my Asus full original...sim 2 was only detected..so did a factory reset and sim came back.
To get sim recognised in CM,I had to wipe usual..install..set up...and factory reset it...hope that clears it up a bit lol

Guys can you check your sim holder lock . I mean when you put the sim in holder check if it is properly fitted. Issue is some SIM cards are thinner than normal and sim holder unable to grip it. I faced same issue.
Also recommend using ASUS ZenUI app called ASUS Support. There are several helpful tips with basic troubleshooting techniques for your device including including SIM card troubleshooting. Please go to Apps/ASUS Support/Assistance/SIM Card/Sim card not detected

Sim Card not detected
Hey guys,
I am having a similar issue. I have 2 Sims, AT&T and GCI (local carrier). AT&T Sim works in both Slot 1 & 2, and GCI Sim works in slot 2 only. The AT&T sim is a standard MicroSim and the GCI sim is a Tri-Cut sim, so basically a NanoSim in a Micro Adapter.
Sometimes when the GCI Sim is in slot 1, it will recognize for a couple seconds then go gray..

I subscribe to the "theory" that some SIM cards are thinner than others and they drop out of slot 1.
In fact, I have 3 SIM cards and they range in thickness by around 0.5mm according to my cheap chinese mircometer. I don't believe that it is coincidence that the thinner ones lose SIM detection more than the thicker ones.
Also it is no coincidence that slot 2 doesn't lose detection becuase the SIMs don't slide upwards out of slot 2, but they do slide downwards out of slot 1.
Do this experiment: Put a SIM in each slot, now place a 3rd SIM in the space between the two. You will notice that it sits easily in the gap between the two installed SIMs with a bit of free play. Put the back cover back on and use the phone normally for a while (a day or two). Now take off the phone back and tip the phone over, does the "third" SIM fall on the floor, or has it been gripped by the SIM in slot 1 as it has gradually slid out of its slot?
Since I put one layer of sellotape on the back of all my SIMs, I have not had one single "SIM not installed" message. I used to get them all the time, especially with one of the thinner SIMs in slot 1 and above all when using the phone in the car (the fully vertical position and the vibrations seemed to have accelerated the SIM slipping out of its slot).
By the way, I never had the SIM slide completely out, but they certainly are not gripped sufficiently in place and slip enough to disconnect.
I had same "sim card 1 not detected" issue.
It worked back when i did soft reboot,.
And no more issue after factory reset
Re @ leftrand earlier on page 1.....
Sorry not been here in a while , but I think this was related to an earlier twrp we used , fixed with the later one I think. So it was a matter of restoring full original bk up,then factory reset then set up again and do another bk up. Keeping original bk up just in case . That was a while back now and should be fixed
facing same problem... only after updating ota. always.. sim 1 is not detected...

I got it fixed bro! the phone does not like the Nano sim cards in the adapter. I happend to find an old GCI micro sim and had them activate it. works great now.
ok i found a solution. i read a earlier reply saying you cannot assess sim 1 whilst using a recovery back up flashed. i was currently using cm13 nightlys and this morning i flashed paranoid 5.1 or so.... i wanted to go back and compare the two but what i did was restore it from a backup.... so what you should do is when wanting to change roms, KEEP THE ZIP FILES THAT YOU USE TO FLASH THE ROMS WITH!!!!!!!!!!!! im still asking you to back up roms (preferably system before you flash) just so you dont hard brick it.
bottom line is back up rom, but keep zip files for when you want to change between roms. hope i can help
I have this problem, compounded by the fact that it seems all Android 6.0 (or possibly all CM based ROMs for the ZenFone?) have an issue where losing cell signal in a dead zone permanently breaks the radio until the device is rebooted. Even if the SIM is recognized, after going through a no signal area, the signal never gets acquired again and the SIM information lines remain blank or unknown. Trying to refresh the networks or providers list throws an error toast.
Hi guys,
I've got a Mi Max 64gb, it was working ok and then it auto updated to MIUI 9 and now i get no signal. If I go into setting, it will show my sim name (three) but thats it. It has no signal and I thus can not make or take calls. The status bar at the top says no service.
I purchased the phone second hand and everything was working fine so did a blacklist check just in case and both IMEI come back clear. Also when I switch from fin network automatically to manual, it will find a few networks but will no connect.
Anyone know what can be wrong? Phone has locked bootloader fyi.

I really have no idea what your problem might be, but the panacea in all weird cases, irrespective of the particular symptoms, seems to be to fastboot flash a official global stable rom with the Miflash tool.
Then you have hopefully a base "known state" to start from.
If you still have no signal, you might well have a hardware problem.

Hi,
I'm not any kind of expert at these kinds of (radio signal) problems today, though I do have a background in communications electronics construction (c.a. 1980's !)
If you did a complete format of everything before flashing the ROM, and it still doesn't work, I would guess you have a hardware problem.
Of course you want to double-check that your sim cards work in other phones.
I've had some rather weird problems caused by simcards.
You should even ask for a completely new simcard from some provider, and not put it into any other phone first.
How you could go about verifying that you truly have a hardware problem, without handing it over to a service center of some kind for testing, I really don't know.
Perhaps someone else has expertise in this area?
Otherwise, you just write it off as a loss, or sell it on Ebay for whatever you can get.
same with me. my phone not showing signal. the simcard is working before. it show no simcard after i flash twrp and supersu. the problem happen after restart phone. now i'm stuck searching this solution. help me.
Hi
So before anyone tells me to just insert a SIM and be done with it, please read this first. I'm trying to unlock the bootloader so I can try flashing different ROMs and radios. I had a perfectly working global version of the Redmi 7. After a phone call, the network went off and wouldn't return.
What I've tried so far:
•Trying multiple Sims known to work
•Manual network selection (fails because it can't find any)
•Changing preferred network modes and bands with the *#*#4636#*#* menu. Nothing happens.
•Toggling airplane mode, several times.
•Factory reset, both from within the OS and from the recovery (Vol Up + Power button)
•Attempting to flash a Fastboot version of the latest global MIUI 11 ROM. This actually fails, saying that critical partitions can't be flashed or something.
•All sorts of bootloader unlock tricks, such as the older versions of MiFlash Unlock, using multiple accounts, etc.
I'm honestly stuck here. Any help in fixing my problem would be appreciated. It could be either getting the network to work, or unlocking the bootloader. I can't bind the MiAccount to the phone under developer options ->MiUnlock status or such, because it detects that there is a SIM in the phone alright, but it just can't connect to any network.

Then you probably should head to a service center to get it fixed.

It was working fine for a few months. It just stopped being able to connect to a network all of a sudden. I swapped SIMs, moved to places with strong network connections (I verified with a different phone) and still nothing.

I had to buy a different phone. We couldn't get anyone to fix it.

Same, i did ask in service they said that they have to replace the whole PCB which will cost somewhere around 6k, so i just bought a new phone by replacing it on amazon for 5k
Same issue im having here but with a new POCO F2 pro. Since inception i was not able to get signal on it
I need to root my redmi 6a but bootloader makes a big trouble for me .for unlocking bootloader there must be sim in that device.but I doesn't have a sim card and even if I insert it, my sim board is damaged. So is there a way to unlock bootloader without inserting sim.
