That sucks.
If a hard reset does not fix it, not sure what to do next.
Did you install the original firmware?

Problem with my connectivity

Hi!
I'm currently running the DN3 ROM and I have installed the latest version of the (v5.5 with update 1).
I'm experiencing connectivity problems where my phone simply loses connectivity. Don't think it is my operator (I'm I Sweden).
I can't post in the dn3 forum (or the developer forum) so I'm asking here hoping someone can help me.
Thanks!

I have the same problem just find a good rom that can run it and check your boot loader if its up-to-date
I'm sorry I do not follow. (n00b of n00bs)
Do I have to flash a new/dirrerent ROM or the same one again?
My bootloader is N7100XXUFND3. is that up to date or an old one?
Ok I'm learning as I go here I my bootloader is N7100XXUEMK9.
Is this good or bad? ☺
Ok I'm not sure if this really helped my problem but I tried to think what I had done the day I started having the problems and the only thing I could think of that I had done was installing Adblock. So I uninstalled it and restarted my phone (for the twentieth time today) and then it worked again.
Could this have anything to do with my problem or was it just a coincidence?
Nope! Didn't help at all. Any suggestions?
Does anyone know if this is a problem with the dn3 ROM or if it just me? Haven't seen anyone else with this problem.

Most annoying! Phone unusable right now.
I don't even get it to work when I restart my phone. But then, every once in a while, it comes back and works for maybe a day or so. The steps again. Says unable to connect to network..

Had to switch ROM. I'm on the Dr Ketan ROM now. That solved the problem though.

Airplane mode on, network problem ZUK Z2

Hello, I'm having problem with my zuk z2. I've had phone for more than a month and it worked fine. I flashed mokee rom and was working excellent. After one update it couldn't connect to network and phone was stuck in airplane mode. It's not showing that airplane mode is on, only when I press power button it says it's on, but nothing happend when pressed. It detects both sim cards but can't get registered on network. Also in secret menu (*#*#4636#*#*) shows Radio off and can't turn it on, or change anything in that menu. I changed a lot of custom and stock roms, with locked and unlocked bootloader, nothing solved the problem. When flash fresh rom it has network (not after every flash), but after some times it just gets disconnected. Please, help me. If someone have solved this problem or have any idea what problem could be.
Edit: I found out that my sim slots IMEI change places, IMEI1 goes to slot 2.
i got the same problem
Same problem here with offician Indian ZUI
damn.. i thought this happened only with china rom.
didn't know it got same issue here.
Same problem
Same problem here. 2.0.133 ST official indian ROM. Any news about this problem?
I have the same issue running Slim 6 on zuk z2
i installed mokee os and the signal comeback again but actually not worked
Yes, I also installed mokee nightly 4/22 and its been working great. Signal is back
me too
Same problem Here.... bought on banggood and after one month network signal disappeared. Today I've unlocked the bootloader and installed Mokee stable ( 13-4-2017) and Lineage 14.1 of 16-01-2017 .... nothing! Still not working.
I suppose it is a failed lot from ZUK delivered from banggood/gearbest/ali ...
I've just wrote an email to zuk support in order to complain about it ...
Yes, because, right now I cannot send back in china at my expenses the equipment and pay for a substitution with another defective terminal.
I've just asked them hoto behave....
I suppose we need to start a class action like the one against samsung for S7 note
However, I'm very disappointed, 1 month and it was looking like a wonderful terminal ...fooooook.
Same problem here. Anybody please share the QCN backup (or valid link to download this) to try repair QCN and IMEIS ?
Same problem here:
I tested different roms and different baseband-versions still no network.
Edit: I also tried flashing it via an external tool - still does not work
http://www.androidbrick.com/zuk-z2-z2-pro-qpst-qfil-miflash-rom-flashing-guide/
I install the Z2plus_MIUI8_6.12.1_zukkati.zip ROM and recover the radios. I feel good!!!!!
Then I installed 2.5.334ST via Qfil, installed TWRP and install other ROMs and everything works fine.
Any Luck guys? Please help if anyone manage to resolve this issue.
Thank you!
Same with me
I had this problem also one month ago, bricked the phone and endly I could it get working again with lingeage on it. Was working perfect.
Today the problem is there again.
When I start the phone without the simcard airplane mode is off (when I touched the power button) with the simcard in the phone it starts with airplane mode on.
Is there a possibility to disable airplane mode complete?
Anyone any idea?
This problem has been around for ages, and no apparent solution to it. Sent it back to warranty and it got flashed frm Custom ROM and back to stock ROM with same results. Useless. Dead.
Got a partial refund instead .
Guys there is any solution?? I have this problem with my Zuk Z2.. Plz help me
Problem Solved
I also had same problem tried all methods described here and in zukfans.eu, but failed. At last discharging(shorting) some capacitor related to network IC did the job.

I got the same problem, could someone help me with repairing this? Flashing roms didn't help
Could you say more information about discharging capacitor? Is it possible to do in home?

WiFi broked

Hello guys, a year ago I tried root my phone and got bricked. After 2 weeks I finally fixed and came back to the stock rom. Since that day my WiFi is not connecting.
I'm able to search and find any network, but when insert the password, the phone try to connect, the signal go down, the message "connecting" appear, and after that appear as "saved" but not connected. I already tried to define a static IP address, but didn't work.
Can I broke the wifi firmware when tried to root for the first time?
Someone have an idea on what is going on?

Follow the unbrick guide method 2. Make sure you follow it right.. Don't skip any parts because it doesn't work. Don't see how you bricked the phone by flashing SuperSU but okay..

Hmm, if that and the unbrick isn't working then you might want to ask yourself it something is broken. Does it connect to other networks?

No I ve used several different hotspots to connect. The strange thing is that mobile data are working.
hmmm take a look at this thread:
https://forum.xda-developers.com/oneplus-3/how-to/radio-modem-collection-flashable-zips-t3468628
If that doesn't work try to flash ex kernel if i remember it correctly it changes something with wifi to.
If that doesn't work then It's broken or you can fix it by doing something else but dont know what, Good luck

Redmi Note 8 Pro doesn't recoginize SIM card

Hi everyone,
After my attempt to flash custom ROM to my RN8P, my device can't recognize my SIM card no more, before that it was working just fine.
The SIM card itself seems to be working just fine (chcecked on other device), it's not a problem with a carrier either.
Since then I've tried: rebooting, turining airplane mode on and off, even switching SIM cards. Also tried to install some other custom ROMS, as well as Official MIUI - unforunatelly without any success.
Has anyone faced similar problem?
I'd be glad for any ideas of yours on how to fix it

Last month I've also faced the same issue with my rn8p like my whole nvram+ nvdata was encrypted (both imei were gone) while rooting my device in PE rom.
I did try a lot, like for 4-6 days but eventually ended up doing this:
I gone to mi care center, and before going I already had locked my bootloader so they could not understand that I have done something which will void my warranty also I closed my developer options. Basically I told them this crap has happened with me while updating to miui12 by normal method and asked for help. They kept my device for about 4-5 hrs and my all nvram nvdata was restored.
(Please don't go for flashing eng rom method it will erase your 2nd sim imei permanently.)
I hope this would help, just give it a try and thank me later
