Wi-Fi disconect automatically - erro

Hello guys, I have a Galaxy Y Duos Pocket Neo model GT-s5302b.* It features the following defect: when I try to connect to Wi-Fi the icon lights up but it is just a moment and automatically turns off.* The device does not find any network. I thought it was a defect in the hardware, however it was not. Now I believe it is the ROM update that caused this defect.* Someone could give me a technical solution for this.

Use dns setting or wipe the phone
If ur mobile is rooted use busy box pro to clear the error

[Q] G900F HOSTS FILE is normal but couldn't add a Google account

Hi,
Dear All,
Ok, the problem is very famous i.e. i factory reset my device and when powered one like a fresh piece, i cannot add google account on my G900F (can't establish a reliable connection to the server).
i have searched a lot over the internet. Read about the HOSTS files description as well. All i found was the modification of the "etc/hosts" with the clients.google.... following "#" so that 127.0.0.1 localhost is only the operational entity.
My device is un-rooted and just for the confirmation of the above mentioned, i opened the hosts file via HTML Viewer (just readonly) and found that the etc/hosts file on my S5 has 127.0.0.1 localhost only and no any other information, which i think should be available for your device to work normal and google accounts can be added. See attached screenshot.
Need your kind help in resolving my issue please.

Try clearing caches from recovery

Still same issue...

Might be worth factory resetting again
How did you access the HOSTS files without being rooted?

did the factory reset 3 times but nothing, issue stands unresolved.
i opened the HOSTS file through RARLAB. Actually it allows you to view the root folder and all of its contents even if your phone is un-rooted.

Could try removing the device from Google Play

Create a new Google account as a test to see if the issue is the phone or the account
If that doesn't help, Id flash a stock ROM through ODIN, this will NOT trip KNOX if you are still 0x0
Are you sure all your data connections are working properly, WiFi/3/4G ?

ok here are some interesting occurrences:
Worth mentioning that i was operating over Wi-Fi.
1) - i flashed a stock Kitkat ANG2 ROM via odin and the problem still persists.
2) - Then i flashed stock Lollipop BOB7 and still the same.
3) - Then i created a new account via the first sign in page on the phone (after flashing the new ROM), and i was able make a new account(through my phone) but still it was unable to login on the phone.
4) - Then i installed a Proxy/VPN betternet and then i was able add an account successfully and also Play store is working fine.
5) - Means there is some issue with my wi-fi adapter routing (may be inside the phone or the carrier) etc.
6) - Then i switched off the wi-fi and enabled LTE (of my SIM card provider) and connected my phone through it, say what! its working fine.
7) - again i tried over the wi-fi and the issue started to happen again
Well, one important thing, i am using wi-fi which is also a LTE carrier (having the google issues) and the second LTE (which worked fine) is by the SIM card operator.
So , is there any problem with my wi-fi (inside the phone) or may be with the operator from which i am getting my services??
its quite confusing at the moment. well i am going to try the whole thing over the Wi-Fi of another operator and will feedback the results.
Mean while any suggestions ??

Reboot the router you are connected to WiFi from?
Doesn't sound like the phones fault, unless you have a proxy enabled in WiFI settings or something, sounds like the issue is with your ISP/Router

Blu Studio 5.0C issue with wifi, bluetooth and wifi hotspot, can't connect

Hi all,
I've been having this issue for 1 week now, and can't seem to solve it.
My device wifi, bluetooth and wifi hotspot stopped working out of the blue. Wifi is stuck on "turning on".
I've already tried the following:
1. rooting the device
2. Removing the battery while it was on
3. Changing date to 3 days before and reboot
4. Changed Power Saving to Off and reboot
5. Removing SD Card and reboot
6. Tried putting it into the refrigerator for 3 hours
7. Tried using a magnet on its back
8. Tried whacking it
9. Airplane mode -> reboot -> left it for 3h in airplane mode -> setenforce 0 -> reboot
10. Spoofing the mac address
11. deleting the folder /data/misc/wifi/
12. deleting the folder /etc/wifi/
13. deleting and recreating the folder /persist/wifi
14. Tried WiFix
15. Wipe Cache Partition
16. Rebooting into safe mode
17. leaving the battery run dry completely, charging it to 100% and turning on.
18. uninstalled recently installed apps prior to the issue.
19. cleared dalvik cache
Many of those solutions were from this post:
http://forum.xda-developers.com/google-nexus-5/help/wifi-stuck-t2721643
I also tried other options that i dont recall right now.
Aaaaand I had no luck at all with any of these solutions.
Though I havent tried flashing a new rom and starting from scratch, many people said it didnt work anyway.
Also I can't run a custom ROM since some apps I use don't allow it.
What I've noticed is that, every time I tried to copy the .macaddr file into /persist/wifi and reboot, the next time i go to that folder again, it is empty. Somehow the system is deleting the files.
Also, when I deleted the files inside the folder /data/misc/wifi/ , the system should be creating new files, but it doesn't.
Please, can someone help me solve this issue? I dont have warranty anymore and I can't really buy a new phone right now, plus, I use it to work.
Thanks in advance.

TC AC822x Manufacturer Settings password

Hi,
My car unit TC AC822x 4.2.2 Jelly_Bean_MR1 (TCAT All In One
Navigator (QZ-Q6902NS16A) from Nissan Almera cannot install and uninstall any apps. I think it is locked. I need a Manufacturer Settings password to check all the settings. Please help.
Thanks.

Attached photo is my car unit.

After tried so many passwords, at last I found the password.
tcat
Yes, that simple.
Manufacturer Settings:
TV - NULL, BOX, ISDN, TCL, ISDBT, CMMB, ISDBT_INN, DVBT, T108/T202 (Default - NULL)
Logcat - Close, Udisk1, Udisk1, Location, SDCard (Default - Close)

Currently I cannot update, install or uninstall any app from Google Play Store or manually install/uninstall apps from SDCard. In this case, what settings should be changed?

I change the "Closed system" from Yes to No and everything works. HaHaHa...
I'm a genius.

Hi,
I checked with Root Checker and found the root access is not properly installed. With root explorer installed, I found "su" is inside xbin folder. How to safely unroot it? It is Android 4.2.2.

Can I use this script to unroot? Is it universal unroot?

Rooting
Hiya Ray. I have had similar problems as you with a similar android device I bought for my car from China. I managed to root it using Kingo(su didn't work for me and a couple of others )... still haven't managed to get any gapps running yet on it though. Will see if I change my Can setting same as you.

Hi Ray, I have the same unit on a Renault Captur. Where were you trying passwords from? I would also like to install and uninstall some apps. I tried the password you used but it doesn't work on mine

[Q] NFC doesn't work on Oreo 8.1

The NFC function lost after upgrating to Stock Oreo 8.1.0, while it works well on 7.1 all the time.
I confirm that I turned on the NFC botton in the settings menue, but the NFC didn't work.
I have unlocked the critical partitions before flashing, also tried OTA, but the NFC doesn't work at ANY TIME.
Anyone can help me? Thanks so much...

It works fine on 8.1 for me but I never unlocked anything. Normally the best thing to do would be to factory reset your phone and choose the start fresh option in the setup menu instead of restoring from a Google backup. Problems after a big update like Nougat to Oreo aren't uncommon and are nearly always fixable by doing a factory reset correctly (fresh start). But since you modded your phone something else might be going on.

Works fine for me.
I am rooted 8.1, Magisk, ElementalX.

I don't have any issues with it and I'm stock 8.1 unrooted.

I have tried third party Oreo 8.1, the NFC works fine.
Only failed on Stock Oreo 8.1.
I tried another time to do a new flashing with Back_to_Stock package 8.1, when flashing system_a.img and system_b.img, it showed a message " Invalid sparse file format at header magic", and after that, it began to flash the system image normally. But as usual, the NFC didn't work.
-----------
Anything related to the mistake? Thanks.

i've got the same issue. nfc doesn't recognize any card or device whilst it is activated in settings and nfc test app says anything is fine.
i'm using android pie but it was the same on oreo. my bootloader is fully unlocked. i always update via back-to-stock and fastboot.

I am running stock 8.1 and NFC didn't seem to work for me either until I touched a tag to the lower portion of the back and it fired. I was used to the sensor in previous phones being in the middle or toward the top. It would not work until it was in the lower 20% of the back side.
Don't know if it will be the same for you, but here's hoping.

yes, it was the same for me. i realized it just a few minutes after my post but didn't find it then. so i couldn't delete it.

I've been fighting to get mine to work, so far nothing. I contacted Essential tech support and they had me clear the cache and showed where the NFC sensor is (bottom part of the phone on the back). I tried using Android Beam to send/receive URL's with my old phone (confirmed that it can send/receive through Android Beam). Nothing is working. Debating whether or not to return the phone and get something else. Any help would be appreciated.
Here's what tech support sent me:
As a verification step, confirm that you're using the correct area of the phone for NFC. Unlike most smartphones, the Essential Phone's NFC chip is located on the bottom of the device.
If you are aware of the NFC position, to isolate the issue further and determine the best way to resolve this, I'd like you to try a few steps.
Ensure that NFC is enabled in settings. (Settings > Connected Devices > Connected Preferences > NFC)
Ensure that Google Pay is the default Tap & pay sevice (Settings > Apps & notifications > Advanced > Default apps > Tap & pay > Payment default > select the desired payment app)
Clear the cache in the NFC Service and reboot the device. (Settings > Apps & Notifications > See all apps > Three dots in the top right > Show System > NFC Service > Storage > Clear Cache)
Attempt to use the NFC service with another app or service like Android Beam (Settings > Connected Devices > Android Beam)

Chiming into this thread - NFC doesn't even show up for me in Connected Devices, on Android 9.

Look under connection preferences in connected devices

I don't have NFC or android beam in my preferences window.

Ok, what do you have?
Edit: just noticed it's you in two threads

Finally got mine resolved. Received a new phone under warranty yesterday. Confirmed that NFC works.
