Redmi Note 8 Pro doesn't recoginize SIM card - Redmi Note 8 Pro Questions & Answers

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

lg g3 no service detected !

Hi everyone
i have an lg g3 d855 EU working just fine for 1 year and a half ,
And lately when i upgrade to Marshmallow and then i stated flashing a different custom roms and they all work fine!
But a week ago I got a strange problem! A sudden msg appear for few second and then phone keep rebooting:
“Mobile network will be unavailable until you restart with a valid sim card”
I’ve done a lot of research and tried them all but still the same probe:
-put a piece of paper on the top of the sim cad
-replace the sim card
- Factory reset
-flashed android 5 the original kdz file got from official lg firmware using my IMEI
-....
So I decided to get it to a technician!
-so he replaced the sim card reader with a new one! After that the phone went just fine for 4 days and then the problem come back, so I get it back to him, so he replaced the reader with second new one and he told me that the reader is not the problem and is 100% working so when I put the sim card and reboot it ask me for "pin code" but when I after put the pin code, the phone keep searching for signal for few second than it stay no service at all.
the technician sad that there is some file in lg g3 responsible for the service detection and stuff like that only be obtained from another working lg g3 and only solution is that he can get those fil from a working lg g3 and put it into my phone and he told me it will be working again for sure !
So please guys help me I’m stuck !! Is there anyone know something about these files or their names?? And if he can provide me them I’ll be so grateful. :good:
Haven't seen this problem before. A file issue? Perhaps do another complete factory reset then do a complete wipe flash of the global rom, using the LG flash tool. Get the rom here http://forum.xda-developers.com/lg-g3/general/lg-g3-android-marshmallow-discussions-t3216143
I use that rom so there shouldn't be any issues. Hope this helps

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.

Sim not detecting

Hello Guys
With unlocked bootloader, I have been to China and used local sim over there.
Now I am back to India and none of Indian SIM cards are getting detected by phone.
I tried all possible options, did reset..downgraded to Oreo also..but no luck. What ever sim card I try, it's not getting detected.
In device info, it's showing mobile radio is off, tried switching on several times..but no luck.
Can someone pls help me ASAP.
Regards
Pavan
Try resetting network settings or hard reset the device and also try flashing factory image if previous doesn't work.
If your bootloader is locked then try reaching customer support. Else, you can try restoring some efs/modem backup using twrp.
Do you get any notification when you insert the sim tray?
I may be wrong just sharing my 2 cents.
Same problem here (or similar, at least).
My 5z recognized the SIM card on both slots, but no signal.
Tried all of the four carriers from Brazil, tried a hard reset, tried the Android Q beta, switched back to Pie, nothing works.
BTW, I've seen three devices with similar problems recently. One Samsung, and two Motorolas. All of them was updated to Pie. Could be some update bug?
My problem was fixed after the May update that was released a few days ago.
Everything working fine, 4G, LTE, etc.

Got phone registered on the network! Too scared to power off, what to do?

Hey All,
So I've had issues with my phone where I rooted it and messed it up to the point where it no longer registered on any networks (tried several providers here in the UK). A few days back trying to get it up and running I managed to get it registered on the network (this after reloading various software versions, some failing some not). After powering it off and back on again with my primary sim, I was back to no network (I have two A70s). Swapped SIMS back (powered phone off) and again, no network.
This morning, I started again (Installing TWRP and was planning to root again):
- Flashed stock firmware using ODIN.
- Unlocked bootloader.
- Flashed vbmeta.tar (v3.3.1-5 from Grarak).
- Rebooted, wiped data/cache
- Rebooted, started going through the setup and noticed it was on the network! (have not flashed TWRP recovery).
​I'm reluctant to power off again and wondered if there's anything I can do now whilst it's working and registered, making calls etc. The reason being, I've got 5 days before I can return the other A70, if not, I'll be stuck with 3 O2 contracts
Besides the usual backup (Google/Samsung/) - is there anything I should do via ADB? It's not rooted and TWRP is not installed, I've literally just flashed vbmeta.tar from Grarak's TWRP post....
did you try installing a custom rom. i am on havoc os n i own A70FN. i believe havoc works on A70F/FN/Q. the only issue it has is of fingerprint and volte but since i don't lock my phone that's not a problem for me.
other than that the rom is stable no reboots no crashes or anything. so maybe try a custom rom just make sure ur model is supported. n besides even if u r afraid of rebooting there's bound to be a day that the phone would need a reboot.
So i say go ahead root it, install a custom rom.
also i remember having this sim issue myself. my sim worked in all the sets at my home except the A70.
i had to get a new sim n it just started working.
Try some other sim in your A70.
Also rooting shouldn't cause such a problem. from my experience i believe its something else.
i have rooted several phones n never got a network issue. i even messed up the the rooting process on the A70 n either ended up with a bootloop or occasional system crash but no network issue

Question No Network Connection (RIL Dead)

Hello everyone. I have a realme GT Master Edition (RMX3360).
The problem I am facing is that, SIM network does not work. SIM is recognised but it won't connect to any network, so basically I cannot use the SIM card even though the phone knows what SIM is this.
I did try:
Factory reset.
Use Force LTE app to access phone information and switch bands (I noticed radio toggle is switched off, I tried turning it on but it won't).
Unlock bootloader, just to increase my chances.
Flash only modem/hlos/... related partitions. Did not work (phone bricked).
Flash OFP firmware. Did not work.
Flash EDL firmware (C.09), which I am currently using. Still same problem.
Different SIM cards.
My IMEI is fine, it is recognised. My baseband version is 4. I did search for the issue in realme community, and it seems quite popular as a lot of people suffer from the same issue on different models.
I live in Sudan, we got no 5G, no VoLTE or whatever. Could you help me please?
I have similar problem after reboot .I can't connect to network or it tooks long time . What helps me is switching to airplane mode.

Switch to global rom maybe your sim card provider not supported switch to Rx3363

Thanks for the suggestion. I did install RMX3363 EU ROM from EDL, it booted fine but the phone still won't connect to any SIM network.
I will also try Russia ROM to see if it would make any difference.
Update:
I did flash Russian ROM from EDL, still does not work. Modem version is also still 4. I will try Chinese ROM next.
Try Latam version this what they put in middle east but so far i think its hardware issue did u try the sim card on another phone? Did you try another sim provider on your phone ? Sometimes if the sim card too old it wont work

That LATAM version is 18 Gigabytes haha. It'd take a few days to download.
I came to think it might be related to modem images as it showed the same version repeatedly on both RUI 2 & 3. So I'll try different modem images.
Also I'll try custom ROMs and GSIs. If it failed I'll return the device as a very last resort.
Update:
I tried latest Official ProjectElixir till date, still same problem.
Update 2:
I gave up the device and replaced it with another one under warranty. I will not buy another realme phone anytime soon.

I have a Xiaomi device too. The new virtual proximity sensor depends on hand movement to function. I don't use MIUI, but it is very fine at all situations.
Also I got a (256/8) GT Master replacement which is surprisingly working fine; being the same RMX3360.

It was already updated to F.03, I heard there was screen flickering or something but I didn't notice any so far.
But I did notice the battery was draining fast on mobile data. Really fast.
Besides, I can always lean on post-market development.

The general feel of the update is slower than the android 12 version
The battery will get better with you try to froze the app you dont use
