[SOLVED] WiFi Completely Broken …

[PeterGuru]

Okay, cool to clear the confusion in my words, my WiFi is not broken, it seems to turn on automatically at times, or when few apps are opened. I have turned off WiFi scanning too, but how is it that its triggered to turn on? I have no clue, I'm trying to find this one..

I have no idea what's going on with your device. I happen to have an opposite situation. My WiFi occasionally and regularly turns off for 1-2 seconds, and then turns on again. Strange!

Both of our problems could simply be a glitch in the current ROM, which may be solved in future releases. I'm hoping.

I was actually reading about this, there is an implementation of this automatic turning on of WiFi on aosp Oreo, you can see that switch on pixel devices.But unfortunately it's not visible to us on our device in settings menu, I suspect that this is causing this, because last time I had turned off this flag forcefully through adb command, and it was working normal. I guess I need to spend some time into reading logs and finding the culprit.

You sound much like me ... I'm never satisfied until I solve a problem, especially with my mobile phone.

Good luck!

Haha ..maybe Peter. We do have a phone in common too, so I guess i could use my little knowledge to share it with ppl, so that it helps them reduce a little bit of time spent on same issue

You're right. When we all work together, we all benefit.

@PeterGuru

Another loss of wifi here. I've not attempted your fix but kudos for your solution and proactive PDF doco!

Hey buddy, similar problem here also.
Out of curiosity for testing oreo in my phone, I updated it to the official oreo build which was released before a couple of days and as of now the OTAs is halted for that build.
The problem is that while I am on any of the Oreo roms, the official one and the lastest 3rd beta, I'm experiencing battery drain problems and some miner glitches so I wanted to revert back to Nougat Oos but then the wifi breaks. The same problem, sometimes shows the SSID then saved then disabled.
Whenever I switch back to Oreo roms the wifi works but on any Nougat build it breaks.
It's so frustrating, I've tried many builds, different recoveries, flashing the modems and firmwares but no luck.
It would be highly appreciable if someone can assist me on this.
Thanks

My phone also had WIFI broken. The phone found a WiFi network but could not connect. The only one that helped was Oneplus Warranty and the phone went to Poland where the motherboard was replaced and now WIFI works.

For those that do not have wifi after returning to Android N from Android O try using the revert firmware:

Here

Remember this only works when you're trying to go from Android O -> N if you're having wifi issues and have not flashed any of the oreo builds this will probably not fix your issue.

You also need to be on an Android O series rom before flashing this revert script and you will need to erase /data after the revert flash as downgrading is not a supported action for /data (If you have an old /data backup it's fine to restore it though)

I was wondering. Would it be possible (would it work) if I flashed lastest OOS (Oreo) and restored my /data backup (which is from Nougat) ?

Some apps may work properly, but others won't.

Personally, I would never restore Nandroid data from one OS to another OS, i.e., Nougat to Oreo or vice versa.

I thought about that, but since the best way to know is by trying, I tried (I had nothing to lose since I had backups). Can confirm it works. I only needed deleting three files to make Wi-Fi and Fingerprints work but aside from that all apps work perfectly.

Wrote about that here: [GUIDE] Upgrade 4.5.15 rooted & encrypted -> 5.0.1 WITHOUT DATA/SETTINGS LOSS

Fun fact: I actually updated to Oreo here because I thought it would fix my Wi-Fi and fingerprint problems but actually the only thing I had to do was to delete those three files (in Nougat). But anyways I'm on Oreo now and it works, so I guess I'm all good.

It was in Nougat 4.5.14 and with TWRP 3.1.1. I did wipe in all and format data.
I installed TRWP 3.2.1 official, did wipe in all and format data. Restart for recovery
I copied the Open Beta 2 archive and flash via adb sideload. I rebooted the system and there was my wi-fi running. :victory::victory::victory:

Thank you.
I wasnt able to flash with the OP original recovery and your method worked in perfection.
Instead of using adb sideload, I copied beta2 to the phone and flashed in TWRP.
After booting beta2 and having Wifi back I download and updated for 8.0.0 (5.0.1) trough "local update" in settings. :good:

Install OTA Updates AFTER fixing WIFI

PeterGuru- thank you so much for this. After following the initial suggestions from others, you stayed with this to help others like me. I got into this mess much like you did - I was flash happy. I did many things, but nothing was successful until I installed the fastboot-adb tools for windows 10, 64 bit. Being able to finally sideload the zip file a the roadblock for me. Thank you so much. With some of the rude dogs I see respond to some posts I and so grateful for you and your help.

Before I do something stupid, it's it going to be okay for me to download and install the OTA updates? After installing the Beta - 2 version of oreo it shows me I have an update to OP5_O2_OPEN_3. IS IT SAFE?

This is to update my progress in my efforts to install OTA updates without running into this WIFI issue (sorry, I don't know the best way to refer to a different thread in XDA

Reflashing with stock kernel fixed my WiFi problem

I installed the XXX rom and I was refreshing it I'm trying too use the Bluespark kernel r 70 yes I know it's outdated. So when it booted it up everytime I press the wifi icon it did nothing. I reflashed stock kernel and the problems gone my wife I fix is related to the kernel when I was flashing so if anyone has the same problem try to just Flash the stock kernel

I need help, my wifi broken and show 02:00:00:00:00:00 mac adress, I tried to intall Oreo version, but I tried by all the methods and didnt work, always do the same, the bootloop, I tried with no-verity encrpted and whatever more. I installed another Oreo ROM like AICP but didnt solve the problem. I tried to overwrite the wlan_mac.bin but the same. Now there are two things very strange. When I install busybox and terminal emulator with command iwconfig or ifconfig dont show the wifi_card, but when I use a qualcomm read soft, it read very well the mac adress of the MAC. I need some help because I came two months with this and I cant solve it. Thank. Sorry but my english is not very well, I hope you can understand me.

Hey Peter, following your tutorial I've got to the sideloading part however I cannot get the zip to sideload because I get usb device not recognized whenever I plug the usb cable in my laptop. I've tried installing official oneplus drivers and I still get the error. Plus when I go to the device manager adb has a yellow triangle
I've tried to search for automatic updates but nothing got fixed..Help please.

 

[hallo dare]

Not sure if it's the answer, but have you usb debugging enabled?

 

[swords90]

Below is my original post; however, I've since solved the problem. In an effort to help others with the same problem, I've written a Guide, which should explain exactly what to do if your WiFi is suddenly "broken" due to flashing issues.

Here's the link: OnePlus 5 WiFi Fix

Many thanks to everyone who offered help, especially subaash and hallo dare, who put me in the right direction.

Hello Peter.

Hello! Although I still have my OP5, I'm now using an OP5T. It really doesn't matter though, because the method of recovery is pretty-much the same.

I've written a new Guide for the OP5T, but as I said above, you can use it for the OP5. Simply exchange one for the other; however, some of the download links specific to the OP5T will not work. You'll need to download the matching file for your OP5.

Download Guide here: AICP Flashing Guide for OnePlus5T

Let me know if it works for you. It should. Don't worry because your problem is related to encryption/decryption, which can be resolved 100%.
