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

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

Thank you sir for your reply.

Device is working again. But what a crazy adventure it was haha
Hi. For several weeks I have had problems with mobile data on my Redmi Note 8T. I have always had a good 4G connection. I usually try different aosp roms, and after installing some of them, I started to lose 4G data. To recover them I connect and disconnect the airplane mode. But I don't understand why it disconnects. I have flashed the stock rom again with MiFlash, but the problem continues. I don't know if it will be a problem with some partition. I recently followed a tutorial to reset the "persist" partition with the "persistbak" copy, but it didn't fix the problem.
Anyone know what might be happening? I would really appreciate your help.
Hi.
I don't know if your problem was same as me.
but my mobile networks were lost (both sims, due to changing rom?). I testet two or 3 A10 roms but problem was loyal(!!). but after flashing an A11 (revenge OS) it solved and sims networks got back again.

Thank you. I think my problem is different. I have not lost the data, I just go from 4g to 3g, although I have good coverage. I recently installed Revenge A11 as well, but the problem continues. Thank you anyway

Hello,
following the installation of OxygenOS 12 beta 1,2,3 when I check the automatic connection 5g, 4g, 3g, ... the connection is not stable it switches between no network, double sim logo, restoration of the 5g connection and the phone ended up shutting down and restarting. when I am in automatic connection 4g, 3g, ... the phone works fine. if a solution exists thank you.
MSM tool.
I've got the same last week.
First I tried downgrade rom. 1,2 times. The third time flashed correct and I was back on 11. But the shutdown was still there.
MSM tool did the job. My phone works again.

Hello! I updated my phone to MIUI Global 13.0.7 Stable (SKHINXM) and suddenly my phone has no service. The sim card is fine and working on other phones like it was before the update. Really unable to fix this issue. If it helps, in the testing window the 'Mobile Radio Power' is toggled off and however many times I try to switch it on, it automatically switches off. Please help! Thanks

13.0.7 Stable (SKHINXM) is a stable beta.
Try to reset the phone or if your bootloader is unlocked flash with this tool

Will flashing the file lead to me losing all data? Apologies if it's a stupid question

Okay thank you! Will try it in a few days time once I am able to give it the time needed.
It is happening to me too, I'm on stock 13.0.4 SKHMIXM, bootloader locked, it happened in 13.0.3 too. Sometimes, I see I have no services, no data, no GPS. But WiFi works great, so if I'm in house I don't always see it, but it means I cannot receive call!!!
I tried to enable/disable sim/data/location/airplane/etc nothing works.
Only way to re-make it works is to reboot the phone, and after 2 or 3 weeks it will happen again, this is the price to pay to have cheap chinese phone...
Try booting into Android with Safe Mode. (and disable Airplane Mode if enabled)
Power + Volume Up > Safe Mode
Or try this:
Settings > Updater > Tap on the "13" several times, this will enable additional Updater-features. Download the latest package and install it.
My guess is that your update may have been corrupt.
Other than that.. Factory Reset or connecting phone to PC and flashing ROM using Fastboot & Mi Flash or Terminal.
I've 13.0.7 and everything's flawless.
So the Xiaomi service center told me that it is possibly a motherboard issue. How can a software update suddenly awaken a hardware issue?
So I had not unlocked my bootloader via my Mi account and it needs mobile data for the same and hence I am unable to flash it since my network is still unavailable even after a factory reset. Any other way I can flash my phone with an older version of MIUI or I will have to submit my phone to the service center?

Could you elaborate the whole process? I do not know how to do this. Thanks
Same issue i am facing after MIUI updation for 13.0.3.0 SJCINXM ... suddenly all networks are vanished ... if i do manual search for networks then i get a message 'Couldn't search for mobile networks' . Voice call is only possible if wifi is enabled.. This is really a horrible experience and i am unable to find out a way to get rid of this situation.. I am using Redmi 9 Prime handset .. Before this update everything was surperb and flawless.
It is still happening with the latest Android 13 and MIUI14, it's frustrating... sometimes when the phone switch wifi/lte/wifi/lte/etc when you go outside, the modem crashes, it internally bootloop and the phone becomes warm and can lose 25% battery in like 15 minutes. Only way is to reboot the phone.
I had a similar problem. Were you able to solve it?
