OPPO A12 CPH2083 no wifi mac? Experts Help Please - General Topics

Just lost my MI 10 in a car accident, , still paying it SIGH. I got a deal on a used OPPO A12 that seller specifically said WIFI was not working as you try to turn it ON and it shts itself off, I had seen this behaviour when wrong roms/modems were flashed in some devices, other was just a matter of resetting network settings, so I bought it. Well, this one is not flashed, it has stock rom from TELCEL (Mexico) and it has a really small (didnt even notice until today) crack in one side of screen. so I think (I hope not) it could have fallen and caused the wifi problem at a physical level, is that possible?
Also I notice it has a recent patch, and that is my main suspicion on a bad update process. Any advice please (Bluetooth also does the same thing, switch goes back to off immediatly after trying to turn it on), I have already reset to factory defaults, reset network settings, reboot phone, turn on and off the airplane mode, nothing makes the wifi work.
PLEASE ADVICE
ColorOS V6.1.2Android9Security PatchNovember 5 2021<----- (THIS IS MY MAIN SUSPECT)hardware version: OPH2083EX_11BasebandM_V3_P10Kernel Version 4.9.117
in the status screen I see that it does not show MAC address for Wi-Fi and also does not show MAC address for BlueTooth.
can this mean that hardware is broke, or can this be due to the last patch?, and how can I try to fix/troubleshoot,
I will try to reflash the last update, would it be wise to try and rollback, is it possible? or flash some other region?

WiFi - Not working at all HTC Touch Pro

Hi,
Having some really odd problems with an HTC Touch Pro....
It was working fine, IMAP a bit slow over WiFi but nothing I couldn't put up with, I was using: 1.66.405.1 then today the WiFi just disappeared... Nothing
Whenever in comms manager I clicked on WiFi I got the whirling WM icon and then nothing
I faithfully backed up and reflashed in case it was something I'd done... No nothing..
I've since upgraded to 1.90.405.1 and still have the same problem!
Does anyone have any bright ideas to how I can get WiFi working again.
I should add that in the Wireless LAN settings screen it says:
Wireless LAN is OFF. Turn on Wireless LAN (but clicking the link has zero effect!)
touch pro wi fi not working
i have the same problem pls someone help
Try to upgrade to ROM 1.90.456.3, I hope you will get rid of many problems in Touch pro.
htc touch pro
can you pls tell me how am i going to do this PLSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
I'm quite happy flashing ROMs (I've installed enough on this one!!!)
But can someone tell me where I might find ROM 1.90.456.3 (it's not in the Wiki)
Or any ROM people believe will fix my WiFi problems?
This is really frustrating!!
I'm having issues too. Wireless had been working fine then out of the blue last night I couldn't get connected back to my wireless LAN. Now its been a day and still cannot. I rebooted my router and one of my access points. This is driving me nutz...
Does your wireless icon even come on, or does it just sit there with the rotating icon and nothing happens before it goes back to the comm manager?
I'm going to reflash this again - can someone suggest a stable ROM that might solve my WiFi problems?

The wireless adapter was active and could see the networks, but it could never authenticate.
I did a hard reset and it's working again but I have to say the connection is a bit flaky in that it drops frequently even though I have a strong wireless signal.
Currently I don't even get that - it just toggles back to the "off" position after whirring for a little while!
I flashed it with the Elite ROM still nothing.
Took the battery out overnight, lo and behold this morning turned it on and the wireless icon appeared, the device promptly crashed!
After the reboot the aerial icon flashed up "network detected" and I nearly jumped for joy as I entered my password, only for it to crash again.
On this reboot the aerial icon was alive with the arrows going left and right as if it was trying to pickup an IP address, but nothing and when I went into comm manager or the settings menu it said wlan was not active (and wouldn't let me activate it!).
I've just reflashed it again with NATF Rom and still nothing, don't tell me I have to leave the battery out for 12 hours to get it?!
Settings>Connections>Wireless LAN>Power Mode - make certain that the slider is all the way to "Best Performance". With the slider anywhere else, connection will be difficult. Drove me nuts for a few days until I discovered a thread for other HTC machines on another site.
Surely I have to be able to turn on wireless first? I can't even do that!
I too have this issue, and have never been able to find ANYONE who can fix this issue,flashing to the latest rom version from AT&T to see if it will work then, if not, i think i might set my phone to factory and claim my insurance/warranty on this phone to get another one since almost nobody is having this issue and those that do say "search the forums" i have, and have found tons of people with it, but no fixes!
I have exactly the same ... because i use wm 6.5 (my own cooked) i thought is me did something wrong so flashed again with a new build,then nothing i went back to 6.1, still nothing seems the wifi controller is totally disapeared from the system unable to comunicate with the controller all progs i tried came back "The pipe is being closed" what is that i cant even see any wifi controller related in the system....
Someone please.anything works fine except WIFI
any recent developments on this issue?
I just recieved a BRAND NEW Fuze from HTC and im so pissed that the wifi isnt working......
I have the same problem ... i have flashed some ROM, some RADIOS, but the wireless still not working ...
Any ideas

"Turn off airplane mode to make a call", radio not working

Hi XDA!
I have a problem with my OnePlus One. I have no signal on it and when I try to make a call, it shows me "Turn off airplane mode to make a call". It must be something with the software. I tried huge some ROMs (stock, custom, KK, LP, MM, even ColorOS), many firmwares, modems etc. but nothing helped me. I was flashing with TWRP 2.8.7.0.5, 2.8.6.0 and 3.0.0.0 with no effect. IMEI in my phone is correct. Both WiFi and Bluetooth works. Only the sim card/signal is a problem.
I cannot "Turn on radio" in #*#*4636*#*# -> Phone info. And here's what's there:
http://i.epvpimg.com/FsVRe.png
I hope you will help me, because I'm out of ideas for this moment. Of course I have "equipment" to flash: unlocked BL, TWRP, fastboot.
Thanks in advance!
https://forums.oneplus.net/threads/...-radio-off-no-signal-tried-everything.415618/ - This might help you. some one had similar problem and it worked. hope this works, good luck mate.
Not sure if i can post links of other forums here, but please feel free to remove the link if it is the case.

Thank you for your answer!
Sadly, I tried it before without success. Now I've tried with few other CMs and other TWRP, but still same. What I have now is: http://i.epvpimg.com/Zdcnh.png
Funnny thing that one time it somehow had signal (a bit weaker than it should and without network).
Solution
I had an identical dilemma this morning. After talking to my insurance, filing a claim, going to my carrier, having a tech look at it, and convincing the corporate office to give me a new phone, I was messing around and decided to try to restart it again.
This time I turned airplane mode on. Then powered off and restarted. Upon powering back on, I was prompted to allow airplane mode to remain on or to shut off airplane mode. I shut it off and service resumed immediately. I hope this helps.
Hi - Few months ago, I upgraded my OnePlus 3T to Lineage 18 and Android 11. today I inserted a SIM card, but I am getting an error "Turn off airplane mode to make a call" Radio Off.
I tried to WIPE/ Clear Cache in TWRP. please help to resolve the issue.
did you solve the problem somehow?

Immediate "failed to conect to network" error when attempting to connect to ANY wifi network. Can't tell if hardware or software issue.

Hello all,
Here are the specs of the trouble phone:
Pixel 3a XL
Android Version 11
Kernel 4.9.232-ga8a0fbc4fb8e-ab696031
So yesterday I dropped my phone a little too hard and the screen stopped working. No damage, just would not turn on. I've replaced the screen myself quite a few times so I thought the internal connection had disconnected. I reset the connection but it didn't seem to fix it, so I took it to a phone repair shop. They did a diagnostic but told me they couldn't work on the phone because some of the graphite coating on the phone interior was scraped off (I accidently did that a preivous time when I was replacing to screen). They told me that the graphite was needed for connections and the motherboard might be broken so they wouldn't test any new screens and I should just recycle the phone?? mind you the phone was still working, vibrating and making noise so that didn't make any sense to me. I thanked them for nothing and left the store.
I tried to reset the screen connection and whatever they did to diagnose my phone actually made the screen work again. I think it was some kind of reset, I noticed all my app preferences were gone and my lock screen changed but I still had all my apps and such. Everything seemed to work except that I could not connect to my WiFi network. Upon entering the password and attempting to connect I am returned with a "failed to connect to network" pop-up immediately. It doesn't seem to be trying to connect at all, it just immediately fails. I can still see all the wifi networks around me, and I can connect to LTE. I can't figure out what is wrong, I've gotten this error with multiple different WiFi networks, cleared the wifi settings, tried it in safe mode, restarted; all have had no effect. I even tried a wifi app and it just returned "failed to connect, enable and disable wifi and try again", which does not change things either.
I noticed that my google play update still shows October 2020, and says I need to restart my phone to finish to update. Restarting has no effect though. I think the restart was pending when I dropped my phone, so the repair store's diagnostic may have messed something up with the update. Should I do a factory restart worse case? I can't figure out if this is even a hardware or software problem, the antennas should be fine if I can still detect WiFi sources but I don't know. Any ideas?

Data disconnecting, no updates and failed recovery mode

Hi all,
Got no answer at general Q&A forum so I'm trying it here.
I'm facing the problem with both phones (Asus 4 Max/ZC554KL and Samsung A10s/A107F). The signal is full, shows 4G, even the arrows, BTSs all around (almost the city centre) but the data connection keeps disconnecting. As long as there's a data transfer (downloads, online radio), it works, once it stops, the connection dies too, still showing 4G/data transfer arrows though. Switching the data off/on doesn't help, the flight mode on/off has to be used to restore the connection. Doing this everytime you touch the phone is kinda....tiring, not mentioning you're getting no messages/notifications till you do it. The sim cards are both quite new (t-mobile cz and kaktus (local lowcost t-m brand)), so it shouldn't be the problem, I was thinking about the problem with contacts to the antennas in back covers as both phones were open few times (was changing the charging connectors due to the slight water damage) but wasn't able to find out if the 4G/GSM antennas are in the cover in case of these phones. The carriers keep saying all is fine from the network part. Both phones were bought new in Asia, being used in CZ now but have all local LTE bands. Asus performs a tiny bit better (in terms of reception) so I decided to dig into the software options. The factory reset didn't help and I realised the phone is still in its original state from the time I bought it (03/19) and offered me zero updates. Even now it doesn't. Tried to download it manually from the Asus website but it always says "error" during the installation and stops it. So I decided to find another way to get it in. Don't want to risk Chinese one-click apps, so I chose Magisk which should allow manual updates with no risk. The collateral problem arose, as the volume keys do not work, so I tried to put it into the recovery mode through ADB. My old computer sadly only has Windows Vista OS and keeps telling me errors whenever I try to perform any ADB commands. Therefore I'm asking you here for help with the following questions:
1. is there any software allowing to put ZC554KL into the recovery mode through Windows Vista?
2. if not, any other way to push any actual ROM version into it? (There's still 7.1.1 from the factory).
3. if not, any other way to get there Magisk?
4. if not, any safe rooting app, not requiring the recovery mode? (Well, I don't need to get controlled by the Chinese comrades)
5. overall, any other possibilities to solve this data problem/keep the data connection working? (I could leave the online radio on (silently) but the battery gets drained quickly and I won't have unlimited data forever )
6. anyone knows where the LTE/WiFi antennas are in these two phones? As Asus has better 4G but significantly worse WiFi reception.
I've heard you're the #1 experts here, so hopefully we'll be able to solve this. If there's any information missing in the problem description, I'm ready to provide it.
Thanks a lot for any help

Can you tell us how the issues started? Did this happen on its own or did this happen because you tried modifying the devices and failed?

You don't have a computer available, I'm not certain exactly what your issue is or exactly what you need to do to fix it, but I can definitely tell you that it will require a computer to fix the issue.

Some devices can't downgrade the android version. I'm not sure if your device is one of them though. If it is, you won't be able to go back to android 9 from 10.
Can you look in system settings and verify that it still shows your IMEI number? If it is not showing or if it shows all zeroes, the IMEI got wiped out during the update. In such case, you may have to restore the IMEI or refresh your firmware via PC. Restoring IMEI or flashing firmware will require a PC.

yes, I have a imei number, it don't show null, it shows my phone number to every Sim I put in, but says disconnected, no radio, turn off airplane mode, no service, network unknown,.. and refusing to let me change network mode to lte or 4g, just says in blue lettering... preferred network mode 22, but every Sim I put in, it auto adjust the apns, to that Sim.. it's a Metro PCS phone, but GSM unlocked
iI just figured downgrading back to android 9, would sorta be like flashing it, as I don't have computer access

The APN is probably saved on the SIM itself. It isn't allowing you to manually change the APN in settings?
Droidriven said:

It isn't allowing you to manually change the APN in settings? es, it will allow me to manually add apn settings, but it doesn't change anything, in network settings the option to manually change it does pop up, with 3 choices.. Auto, 4g, auto 3 g.. Etc, but the blue network mode 22 stays,.. Did talk to best buys, geek squad, and one tech said if it's in blue, what happened was when the new update to 5g was sent out it was supposed to wipe out the 3g options from phones, and some phones didn't take it so well, but they say can be fixed by flashing it.. I'm still unsure what that means, and would still need to do it with a SD card, or male to male cord to another phone.. If it works like that?, I was hoping for a new update.. But believe the phone probably isn't receiving signal at all now, as some app even on wifi say to turn on wifi.. Or data..

If there is a public library near you or some other place that has computers available for public use, you can download your device drivers, your stock firmware file and your device's compatible flashing software then put them on a USB flash drive and use the PC at the public place to install your firmware.

I've seen a lot on no signal stuff, I think everything can be adjusted to work except this network mode 22 in blue, if you try to make a call, does it say to turn off airplane mode like mine?, have you done the dial pad thing, *#*#4636#*#*?, the top option, in there, my network says unknown, radio off,, here, most people can manually change the network settings to whatever they needs, GSM only, CDMA only, gsm/CDMA automatic etc, and this normally fixes most issues, I have a bad update I think, that was meant to remove 2/3g options out of my system, and messed everything up, as I have x2 stylo 5s and both stopped working, one just froze on LG symbol, and he other lost network radio signal, I tried to hold down power and vol down on other one, and it turned off, and never came back on, i've tried to unhook battery, and drain power... nothing, I switch batteries, etc, nothing, I have not been able to fix either phone, I sence bought a LG k31, and 3 days ago, it started ghost touching, scrolling on its own, clicking on stuff, I'm using it as a hot spot, to power the stylo 5, I don't mess with settings, add anything, drop em, just normal stuff, I dnt know what's going on, but I'll cave man it it before being a apple guy!

yes, and I just heard lg isn't making phones anymore, and are not supporting their old ones
I got the solution,
I have been using my lg since 2020, it came with android 9 it was perfectly fine till android 11, in july 2022 i updated it to 12 since i got the update, but after the update it made it worse so laggy unresponsive home buttons and back button top bar swiping completely went into chaos, due to this i downgraded to android 9 it was well again but no network in settings it showed network mode 22 so i tried to flash android 10 same issue and then i flashed it back to 12 everything went well network came back and even the phone works so fine till now, network gone like network mod : 22 means we have taken our device too back this is the issue flash with stock rom it will be fine.
