I'm just having a lot of problems withmy xperia xZ3 (H9394). In Monday, I updated google services and after that, the phone didn't connect to wifi or mobile data. I make a factory reset but it didn't work. I assumed the problem came from that update and everything will be fixed if I downgraded firmware. I tried first with sony emma flashtool, but I needed the bootload of my device to be unlocked. I unlocked it (yes, I screwed it) but emma said "no available services matched", so I tried it with newflasher and downgraded firmware, but it stayed in bootloop. So, I return to original firmware (52.1.A.3.92-R4C). It boot normally, but I have the same issues with wifi and mobile data, sometimes it works, but connects and disconnects constantly.
Someone can say me what can I do? I know that I can't relock bootloader.
@MartinX3 I know that you are a master, colud you help me?
Thanks! <3
I would look if that problem is the same on a custom ROM. (But flash on both slots and boot the latest stock first until you reach the desktop)
Or if it only happens with a specific WiFi, maybe the router need updates or a fix.

Thanks for reply.
What did you mean with flash both slots?
I have tried it with rom H9493_Customized CN_52.1.A.3.92-R14C, wifi and mobile data works. The problem now are the google services. I think it's a firmware problem...

Hello. I flashed again with 52.1.A.3.92-R4C custom Taiwan downloaded from xperifirm and it work for a time. First, I didn't have any issue with wifi and had 4G signal, but after hours, the problems came again and lost mobile and wifi signals. At that moment, I couldn't even activate wifi, when I turned it on it turned off immediately. For some reason, I activated airplane mode and turn on wifi and it worked, but when I turn off airplane mode, lost wifi signal. It's very strange. I think it's some problem with mobile data or something.
I will flash A/B slots. For that, I need the GSI and ASOP (Android 10.0 – Kernel 4.14 – Tama) img and I must do it with platform-tool, right? I don't need a firmware in tft?
Thanks.

For the custom ROMs you need to have the latest firmware on both slots and booted once until you reach your apps.
Then just follow the instructions of the XDA threads and don't forget a fullwipe.

Hello again. I downloaded Android 10 GSI from https://developer.android.com/topic/generic-system-image/releases and AOSP 10 for XZ3 from https://developer.sony.com/file/download/software-binaries-for-aosp-android-10-0-kernel-4-14-tama/. I used the latest platform tools. I flashed oem_a, oem_b, system_a and system_b. After that, I did a wipe with fastboot -w command and finally reboot my device.
I checked that everything worked fine. Wifi and both sims worked fine.
After that I flashed the firmware H9493_Customized TW_52.1.A.3.92-R4C with newflasher and wiped it again. Did I do everything correctly?
Thanks.
If anyone wonders, no. It didn't work. I tried with custom roms and it was the same
I tried everything. I tried installing LineageOs, pixelsperience, Sony AOSP 10, 11, gsi 10, 11, and stock roms and nothing. Sims are detected some time, but stop after a while. i put an sd card instead of a sim card and it was not detected. I assume it is a hardware problem.
Well, thanks for helping
I'm having this exact same problem on my XZ3, thought I was going crazy but makes me think it's maybe not hardware related to find someone else with the problem...

After installtion of ROM (without installing other APPS for ROM) mobile network was working fine and I was able to make/receive calls. I used it for couple of hrs, the only thing I noticed that I was not able to turn the WIFI on I thought this could be because of other apps so I installed other apps. Immediately after installing other apps network is gone even if I try to search network manually it says "Error while serching network" and still I can not turn my WIFI on. Any one else having same problem?
I reinstalled ROM to check this and again same problem. No network & No WIFI.
About wifi, it's said in the first post that it only works with static ip, although there's a fix for that, so i used it and my wifi is excellent now.
About the network, i really can't help you but mine is fine...Have you tried to wipe data before installing the rom again?
This ROM need nAa11 kernel to work ot of the box! Why you need alf's kernel?

Hey guys,
I have a Z1 C903, which doesn't work as a wifi tether nor bluetooth tether. I can turn it on, and other devices can see it, however when trying to connect, the signal drops completely.
If I wait the signal will restart and become full strength, where I will need to manually connect, which proceeds to the signal disappearing again. I've tried unsecure, wpa2, wpa to which I have no luck either. Devices such as laptop will say limited connection, whereas android tablets and phones will refuse to connect and will say "Saved, secured with WPA2" or something else if i change the password method.
I've tried searching for any reports of wifi tethering not working, but the problems seem to be different from my situation.
More details on my device:
It has an unlocked bootloader
Now running Paranoid android
Problem occurred on stock 4.3, nut 4.4 (I assumed it was a glitch on Sony's drivers, and have waited for months now for a patch)
Could a faulty TA do this?
Any ideas?
Am I f***ed?
Cheers

Flash your phone by flash tools including wipe apps log and cache and system
It should solve your problem
And of course first re-lock your BL and flash to stock Rom

Sorry about late reply, I am out in urban areas without internet connection. I'll try doing this tonight.
Am I right in assuming all Z1 CM ROMs have this problem, if I must install a stock-based ROM?

Oh, sorry I forgot to tell you
You should use stock rom

You can try to change the name of your phone (Network SSID) to a simpler form instead of default.
I got it working
I got it working thanks to your suggestion, Saeed.
I flashed the stock ftf from the mega thread and that restored my tethering capabilities. I then proceeded to reinstall the ParanoidRom and now the tethering works as well.
I'm not sure what happened, but I'd assume something went wrong when upgrading to 4.3 and the problem stayed when I then upgraded again to 4.4 and then to paranoid.
Thanks
Suddenly, I am not able to activate WiFi using Settings. It just hangs for a while and then tells me that Settings isn't working.. If I power off and then on, everything works OK.
Can I fix this?
Thanks.
Is this on original OxygenOS ROM? Sounds like your wifi driver crashed and burned, probably caused by something wrong in the driver or the userspace.
All you can do is make sure your system is updated, and if that doesn't help, do a factory restore and hope for the best.
I have unbricked a op3T 128gb today and i'm having the same issue. i bought the phone bricked and i have no info about the history of it. after the unbrick process i have oxygenos 3.5.1 android 6.0.1 on it. Kernel is 3.18.20-pref+
if i think about it someone might updated it and now it needs the modem updating or something? how can i update everything to latest oxygenOS trough Abd or without any wifi?
Wifi mac address is 02:00:00:00:00:00 hmmm....

You can always download the latest full OOS zip to the root of the internal storage, rename it to update.zip and the just enter normal recovery using volume up and power to let it install.
I´m running latest stable MIUI from XIAOMI.EU and I can´t connect to any 5Ghz WIFI.
I can see them in my wifi search and after I type the right password it can´t connect.
I have tried flashing other MIUI roms same problem.
It only works with AOSP roms.
Anny suggestions?

For it only to work with AOSP is strange, I am using Xiaomi.EU and do not have any issues with 5g.
My guess is that you are using AOSP ROMs with custom firmware.
If you want to switch to Xiaomi.EU try a full wipe, including formatting the userdata partition. Reboot to fastboot and flash fastboot flash an images rom which will restore the partitions back to the latest official firmware. You can find links to the images rom on my all in one persist thread, be sure to make a full twrp backup as I suggest be on the Op.
After flashing the rom, reflash, Twrp and then install Xiaomi.EU. I am certain that you will no longer have issues.
Thanks! Will give it a try.
So I formated data in TWRP, then flashed latest global with flashtool , flashed TWRP then formated data again. Flashed latest Xiaomi.EU stable.
Still same problem .
It finds the network and then I type the password, it says connecting and then nothing happens.
I've the same problem with latest global, my MI 8 is "untouched"
Edit:
Sorry, it was a router "problem", now solved

It seems that you have ruled out the phone being the issue.
The post directly above your solve their issue by doing something to their router. I would assume that they simply unplugged the router for 15 seconds ( called power cycling) or maybe they even had to reset the router. ( Should not take more than 10 minutes) These types of issues happen all the time with phones, especially iphones. or if your router sets uses internal TCP/IP static addresses.

The problem occurs in different network home and work.
I think I found the issue, the region is fixed at KINA. I flashed some region fix and then it's possible to change, but it reverts to china on reboot.
Now how to fix this issue?

That is really weird. Where did you get the region fix? Are you sure it's not outdated? All of those mods posted by Agimax are for Miui 10. That is unless he made new ones.
Use the network option ( see attached) The region option was removed from Xiaomi.Eu. However, they use the global devices radio drivers.
I'm having the same problem for a big while now. I think it was since MIUI 12 came to my redmi note 7.
I just can't connect to any 5Ghz connection and I know that it's not router-related.
I have never flashed any ROM.
Hi , its been a year since i bought xiaomi mi 9-global rom(128GB) and all work properly.
if im not mistaken the first rom when i bought is MIUI 10 , then the last time i update if im not mistaken is around september in MIUI 12.02 for the latest security patch.
Suddenly problem occurs recently maybe around a week. where my Wifi & Bluetooth disconnected by the system and cant be turned on but it fixed it self as i restart and now its never fixed.
I already some of fixed below :
- Restart devices
- Wipe all data
- Factory reset
- Try to flash the ROM from official one MIUI 12.02
- Following some tutorials that reset bluetooth and wifi settings
- Try downgrading MIUI version to 11
but still didnt work the Wifi & Bluetooth setting always crash & cant be turned on , try CIE or CIU test found out that the proximity sensor also didn't work.
I also tried some tutorials that do in EDL mode to install persist mode but its not working due to the Authentication it says" i dont have the permission"
Is there anyway i can fixed the Bluetooth & Wifi in this device?? The Mobile Data is still working and other features still working except Proximity Sensor, WIFI, Bluetooth.
Is the only way is to let the xiaomi store fixed it?? this is my only phone so i need it alot and the office store probably going to take long since pandemic.
Please help me Xiaomi Pro's out there :crying:
Edit :
- my xiaomi account already match with the phone the proof is i can unlocked OEM using the xiaomi. But it seems i still dont have permissions to flash EDL.

I think it's safe as miui could be.
But be shure to follow step by step and take right rom version. If it's working you can flash original miui or custom roms.

Thanks for the suggestion, after i tried to flash to EU ROM i got new MIUI version which 12.04 , in global its 12.02. However the problem still happening or still remain unsolved. The bluetooth & wifi still cant be turned on, i tried on CIT it also not working and everytime the i try to open wifi & bluetooth settings , the settings always freeze and crash probably because it error. Is there any other solution you can provide?

I think, if you have done a really clean flash with formating data, that it's a hardware problem.

yes, i did i already follow the instructions & having no error at all for the ROM and other stuff except the WiFi & Bluetooth.
But for me its just really weird, my phone looks still great from outside no bend, dent, or crack it never fall as well.
The problem starts occurring by itself like the system is forcing the Bluetooth & WiFi to off then at some point the WiFi is connected but not transferring any data after restart everything fixed then its not working at all, which when i tried to turn it on it will freeze or the system not responding or off by itself.
btw appreciate your answer, i'm still waiting for other solution if possible :crying:

In my personal opinion there're 2 possibilities
Damaged hardware
Or
Modem Partition wrong or damaged
MODEM or RADIO - the phone's radio
Also called baseband, it is responsible for signals and on older devices may control wifi, bluetooth, and GPS (on most newer devices, these are handled by the kernel and ROM). Upgrades are country dependent and may improve or diminish battery performance, network signal strength, and roaming capability. It is also sometimes required to have a minimum Baseband version to use a ROM so that the RIL will play nice with the Baseband.
Modem firmware is a mini-OS for the cellular radio chip which has its own processor. Firmware is a general term, firmware exists for a lot of things on phone. The wireless chip for WiFi, GPS, and Bluetooth often has a firmware as can the GPU core among other things. These firmware files are usually located inside the SYSTEM or VENDOR partition. The modem firmware is special because it has its own separate Baseband Processor (BP) so the firmware is left out of the system image in its own partition.
Modem is not an Android-specific partition. It is tied to the hardware of the phone, but the kernel has a code allowing Android to interact with the hardware. But the baseband processor (BP) - which runs modem and is responsible for all communication through mobile networks e.g. call, SMS and internet - is totally isolated from Application Processor (the one we call CPU) and is not governed by Android kernel; it runs an independent RTOS.
May it helps you for getting a solution....

Thanks for the long and detailed explanation . My mobile network & GPS still work properly without any issues.
but idk if the Bluetooth & WiFi chip maybe fried inside
Maybe i just dont have any other option except to fix in mi store.
Once again thanks for the help :fingers-crossed:.
