[SOLVED][HELP] WiFi not working (I tried almost everything !)

Hello everybody !
Ok, I am use to not ask any help, and to find out by myself. But I have to admit I don't have any idea remaining to solve this problem.
Let me explain you the situation :
I explain everything with details to not waste your time when you will help me !
When I first bought my Zenfone, everything worked properly. Then, I decided to flash a Custom ROM (to remove the bloatware, and to get the others optimizations). So what I did :
- I unlocked the bootloader,
- I flashed TWRP,
- I installed my custom ROM (SuperZen R15, super clean install) => at this moment, everything is working perfectly,
- I installed a custom Kernel (ProjectT, v56) by fastboot => here we are, the problem just appeared.
At this moment, the WiFi issues appear. When I boot the phone, I can turn on the WiFi (in most cases), then, WiFi just turn off. It is impossible to activate it again. In the best case, I can switch on/off the WiFi, but as soon as I download something, the WiFi just turn off immediately. Often, I just don't detect any network. In the worse case, it is impossible to activate again the WiFi, the ON/OFF button is grey.
So here is what I tried to get it back :
1) put the standard kernel with my TWRP backup => no success
2) flash another ROM (CM12, Paranoid Android, Barebone,...etc) => no success
3) flash my whole TWRP backup (system + kernel) => no success
4) flash the official Asus ROM (recovery.img, system.img, boot.img, droidboot.img) => no success
At the moment, I started thinking that maybe the WiFi just "forgot" my WPA key. So I modified the build.prop :
5) modification of the build.prop by adding the line ro.securestorage.support=false (instead of "true") => no success
6) flash the last Asus update 2.20.40... => no success.
...
I haven't any idea remaining !So I need your help ! This problem seems very standard, but I just couldn't find any solution yet !
P.S : I almost forgot. I talked about the wiFi signal, but it is exactly the same for the bluetooth signal : working on first boot, then when I use it, it just stop working and disconnect itself, and then, impossible to activate it again (grey button)
=> My last idea was to flash the radio directly by TWRP, but I didn't find any radio files for the zenfone 2...
Many thanks for your help, and thank you for reading everything !!

Try setting your phone as a wifi hotspot. If other devices are able to detect your device, it is a software issue. Or else, you might have to book an appointment with the Asus service center

You're such a genius ! I will try this evening ! Thanks a lot !

Didn't do anything. It's not working. I was thinking my wifi was just broken, but something creepy happened this morning. The Wi-Fi worked again (I downloaded one thing to be sure !) and then... My phone froze, and reboot... Is the devil inside my phone ??

SOLVED ! If someone has the same problem, just flash the stock ROM via ADB Sideload !
Step by step :
1) You go here, and download your version of the stock ROM : http://www.asus.com/fr/Phones/ZenFone_2_ZE551ML/HelpDesk_Download/
2) (If fastboot/adb drivers are installed) Go into your recovery (Advanced in TWRP)
3) Connect the phone to the PC, type WINDOWS + R , enter 'cmd'
4) Go into your firmware directory you just downloaded, and type : adb sideload 'thenameofthefirmwarefile'.zip
5) Wait (a loooong time), and here we go, reboot, and your phone work again.

can you tell me what firmware you used exactly? because i tried to flash the first one, from the asus page.
But it says that i have a newest build and it doesn`t lets me past trough the installing part.
I am also having troubles with my wifi and i would like to fix it

Hello ! I don't remember exactly, I went on a website and selected the right version for my country ! But my problem wasn't solve at all actually... I brought my phone to the store, and they told me my motherboard was just burnt. They changed everything, and now it works like a charm ! Be careful with the custom kernel, I'm pretty sure that's how my phone broke (I'm very careful with batteries,...etc)

Well thanks anyway. I will try to take the phone to te oficial ASUS services from my country but i don´t think they give a new one. I live in Uruguay and this cellphone is not at sale over here

Does sideloading the firmware wipe your apps? Or is every thing still there when its done?

LineageOS for Oneplus One and problem with wifi and HDR in camera.

Hello everyone.
I have 2 problems with LineageOS on Oneplus One.
First HDR does not work properly. I can not do a photo with HDR enabled.
My another problem is with WIFI. Many times I have lost connection to internet without report, and I must reconnect manually. My phone is connected to router but without internet. It is very annoying problem for me.
I fashed:
lineage-14.1-20170206-nightly-bullhead-signed.zip,
Gapps Android 7.1/Lineage os ARM Pico ( other did not work because of low free space of disk. I have 50 gb free. Weird )
Latest Super Su.zip
I flashed them all at once. Was it good idea? Or I should flash them separately ?
Of course I did clean wipe before installation and Wipe Dalvik,cache after installation.
Thanks for replies

I have the same problem with the wifi... i don't know if it is a firmware / modem problem... i have this version: "2015_05-15_DI.3.0.c6-00241"
The camera problem its reported and with be resolved in the future...

And another problem. My phone has not been detected by computer. I can not transfer music
Any idea to solve it? There is an icon "eject MTTP" but no folder with phone on my computer.
File transfer is not working, but photo is working. Weird
I solved problem with the wifi. Just instal the latest room
Hi.
I don't why this worked for me or if it might even work for you, but what I did was locate the following file 'wpdmtp' in C:\Windows\INF.
I right-clicked on it and updated it.
Suddenly, my PC recognised my Lumia 535, even though if I try to update the driver I still get the same error.
Well, as long as my phone shows up, I don't really care. Hope that helps.

Screen Rotation Problem

I have a problem with the screen rotation sensor. after a few hours the sensor stops working. When i restart the device the sensor works again for a few hours.
I set up my device right after the purchase with the lineageos, with the stock rom I have not yet tested, but with superior os (9.0), I have the same problem. Does anyone have an idea how I could solve the problem? Is it possibly a hardware problem?
I have also tested with the firmwares 10.0.3, 10.0.9, 10.0.12 and 10.0.13.

Not exactly a hardware problem. I had the same issue on LineageOS and told the developer to look into the issue but he has abandoned the ROM so we're not gonna get a fix for that. Some Pie ROMs break the sensors of the device. This is not limited to the rotation sensor but also including the proximity sensor and some camera issues. I suggest flashing Oreo in EDL mode and then using another ROM like MIUI (in which everything works the way they should), if you are trusting the developers of that ROM. Cheers.

Thanks for your help. Miui is not an option for me. I operate my mobile without Google services, so Gapps must not be pre-installed. POSP v3.1 would be my first alternative to Lineageos, but I hope someone will develop it further.
Can you still help me how exactly I flash in EDL mode?

Download and install MiFlash 20170425, Qualcomm Drivers, ADB drivers and platform tools.
Download stock fastboot images. Extract them in root drive (suck as D:/). Fastboot / EDL do not want folder names with spaces.
Put your phone into fastboot mode (by long pressing Pwr + vol- until Fastboot Mode logo appears)
Type in Command Prompt or PowerShell: fastboot oem edl
Phone will turn black and have blinking LED.
Open MiFlash. Locate the extracted fastboot images folder.
Click refresh. Should display S/N of your phone and its status.
Select 'clean all'. Do NOT select Clean + Lock, as it will lock bootloader or make things worse.
Start flashing by clicking flash button, and wait patiently.
When it display 'success', long press power until you can see 'Device Unlock' warning screen or AndroidOne splash screen.
And you're basically done EDL'ing phone.

There are a lot of ROMs you can try. Most of them are more up to date compared to LineageOS. Superior OS, ViperOS, Resurrection Remix are your options. Can you tell me how did you de-googled your phone? Don't you have problems with GPS or other stuff without Google Services on your phone ?

thanks for your help, i'll try to do that in the next weeks

All I have done is not to install gapps
GPS runs without problems without Google services (I use osmand for navigation), Whatsapp I don't use, I have Threema, you can set polling.
Because the Google camera is much better than Open Camera or the standard camera from Lineageos I installed MicroG, so the Google camera works.

Hello, a while ago I had this same problem, but I was successful because my cell phone got wet on the top (where I imagine all the sensors are). From there accelerometer, gyroscope, compass, proximity and light stopped working.
Yesterday I was trying to install DerpFest ROM and I did not succeed, I tried it more or less 15 times and threw myself into bootloop, so I reinstalled stock ROM Pie 10.0.16 and the sensors from nowhere started working again, but after a while, When charging, the device rebooted only 2 times. After such reboot I deactivated the sensors again.
I have tried to fix it by reinstalling Stock ROM and cleaning the system files through the TWRP "Repair" option, but it does not work.
Did anyone find any solution for this?

The solution for this problem is the kernel. The installation of POSP Rom solved the problem, probably because of the included kernel. Actually i have the lineageos rom with the butterfly kernel and it works also, without this kernel i had also this problem with lineageos.

Mi 10T Pro rebooting issue

i recently updated the software to lates Miui 12.06. after reboot. i started getting alot of issues
1. sim activation problem
2. constant reboot due to google apps.
so i disabled mi cloud and then no more issue with sim activation but the phone is still randomly restarting.
so i have done multiple factory reset and still no solution.
so wanted to flash the stock rom but not able to find it; the one i want to download is the global version but the link is broken (this is from official Miui site)
if anyone have any solution please share.

hello. i am on 12.06 too, so far i have enabled usb debugging on this phone and put it in ADB mode using windows powershell and then i run Xiaomi ADBFastboot tools concurrently. i have disabled a lot of stuff that i thought i didnt use from the fastboot tools. only calendar, playstore and photos left and what ever similar app i can get from fdroid i, disabled the Mi application. i got myself a blokada to block ads. happy for now. i did have sim not detect at one point, i removed the sim 1, gave it a good rub of eraser, make sure its flat, and then resit and make sure sim toolkit is there, happy campers there
