Can't get the phone to recognize data connection through USB port

Sadly i had to come to the painful conclusion that my problem relies at this point on the data detection of the phone itself.
I have read tons of tutorials pointing to adb or fastboot upgrades and different stuff and methods to update. I'm stuck in 2.20.40.139 and cannot find an update within the OS. I will enumerate now the things i see in order to clarify this situation.

_USB debugging on or off makes no difference.
_MTP or the other mode returns nothing. No detection on device manger in windows.
_Phone always charges when plugged to USB ports.
_Tried 4 cables and 3 pc's all of them tested with other phones and tablets.
_On fastboot mode nothing happens and device is nowhere to be found.
_ADB is the same. adb devices shows nothing for this.
_Recovery returns an error as if it tries to update something that isn't there MOFD_SUPDATE.zip
_after that error i get into recovery pressing power+vol up for a few seconds.
_did a factory reset on the phone and wipes in recovery.
_copied file in root of the phone. Detected the update. failed when trying to apply.
_bootloader in fastboot shows unknown. serial is 0123456789ABCDEF or something like that (serial was ok before i used the bootloader unlocker from ASUS website)


i can't think anything else for this right now... it's really driving me crazy since android works without an issue. Phone is not rooted or even has been tried to root.

If someone knows or can think anything regarding this please help me out. There's nothing i like more to share thoughts and ideas to have this updated.

Thanks in advance,

Android Auto USB connection problem ?

Is there anyone success in connecting this phone to a car using "Android Auto" ? I try many roms in the kenzo development section but none of them makes the phone being detected by the car through USB. I had another Mi Note Pro on the CM13 rom and the phone is connected to the car through USB cable.

Problem with Google services connection

Hi,
my phone is:

• Redmi 3 Pro


• Android 5.1.1 LMY47V


• Miui Global stable 7.3.2.0.0 (LHPCNDD)

After two weeks of perfect usage, a problem with Google services connection appeared:
can't sync, can't enter gmail, Play Market, can't add new Google account, etc.
I've tried:

• deleting Play Market's cache - no results


• removing current Google account - no success, "doesn't permitted by administrator"


• add new Google account - no success, since there's no connection to Google services.


• reinstall Google services - no success, phone isn't rooted


• back to factory defaults - worked for another two weeks, but then the problem reappeared.

Two weird things:

1. once in a while, in a couple of days, connection reestablishes for a minute and a sync is done


2. after a restart of the phone, connection to Google is good, but disappears after 2-3 minutes.

Is there any things I can try to do before flashing a new ROM?

USB connection issue

Recently started having a problem where even without a cable plugged in, this keeps popping up intermittently.


Also after changing battery, I'd sometimes get a firmware upgrading screen, telling me not to unplug, again with no cable. Only way I could boot normally was plug in & restart.

I've cleaned & checked connections & they look fine.

Anyone else witnessed similar?

Can't switch back to 3G or LTE. Left with only 2G connection.

Facts:
- OnePlus 2 (European Edition, Germany)
- CM13 (13.0-20160721-NIGHTLY-oneplus2)
- Provider: Telekom (Congstar)

My OPT refused to switch to anything more then EDGE (2G) a few days ago. First I though the network was down but after a few days I checked with other phones and only mine wont switch to 3G or LTE.

When I tried to cheange the "prefered network" toggle, I switched it to 2G and now I can't switch it back to 3G or LTE. The options are still there but when I select them they instantly switch back to 2G. Even in the Advanced menu that you can enter by dialing *#*#4636#*#* I can't the setting is fixed to "GSM only" and I can't change it.

When I search for network I can only find 2G networks. In the Results are only Vodafone 2G and Congstar 2G which is my provider.

I would love to get this fixed without completely reflashing my device. Does any one else have a similar problem and maybe a solution?

No internet connection & No USB connection

Hi!
This night I restarted my phone. After that I turned on WiFi/Mobile Data, it connected successfully everytime, but I had no connection to anything. Messenger does not load, Chrome-Firefox-Simcity crash after I start them. I connected the phone to the PC via USB. If I select install drivers and the LG app the PC shows the phone correctly in TotalCommander and so on... But if I select MTP, the phone disappears...
WHAT THE HELL?

Can't get connection to ANY carrier

Hi! I'm having some mayor problems with my OnePlus One.
For some time I have had problems getting calls and sms when using 4G but it seemed to be a problem with my carrier but 2 weeks ago I dropped my phone and the screen broke so I bought a new screen and replaced it. After that the connection to my carrier dropped randomly and now after trying to fix it in different ways I can't get any connection at all with any carrier !
What I have tried so far:

• Factory reset


• Reinstalled CM


• Put paper under the sim for tighter fit


• Turned the radio off and on and restart phone


• Change pin code


• Replace sim-card


• Tried different carriers on my phone (my simcard worked on other phones so it is the OPO that is the problem)


• Total restore by fastboot-flashing


• Installed OxigenOS 2


• Tried all modems from the modem collection on CM and Oxigen.


• Retyped the APN by hand


• Opened the phone again and checked that all cables are connected well


• Tried manualy connect to my carrier under Network Operators

For a short time of maximum 10 seconds I got a 4G connection twice in now 3 days of trying but then it stops working again. It feels like a hardware problem BUT I can see a lot of different carriers under Network Operators but when trying to connect it loads for ever and then says "Can't register to your carrier". I called my carrier and thay said nothing was wrong from their end and when I tried on other phones it worked flawlessly.

I'm really out of ideas now and I don't know where to go from here. I really hope someone of you knows that might be the problem!
Thank you so much!

Android 6.0 shutting down data connection (Wifi and mobile data) in standby

I am not sure if this is a 6.0 problem or the problem of my new umi super so please excuse that try finding answers here first. My Phone is shutting down mobile data and wifi connection when going to standby.. not immediatly but after an undefined time span. Calls and Calender notifications are still comming throught but i recieve a billion whatsapp messages at once when turning on the screen. any ideas? i have never used clean 6.0 just sultan roms up to know, so i cant really say if this is a basic problem, an umi problem or just settings i screwed up.

Thanks,

HTC One M9 NO cellular connection

Hi,

First of all, I'm not sure if this is the right place for this thread so if it's not I'm sorry.

I'm not a complete newbie about ROM custom and flash... But I'm not an expert either :)

This is my situation :

I have a HTC one M9 that I bought in Canada. Yesterday I flashed the last version of the TWRP and I flashed the last version of the Venom ROM.
My problem is that with this new custom ROM, I don't have any cellular connection : No DATA, no phone reception. I tryed to flash the last Cyanogenmod 13, and I have the same problem.

Did I miss something ? I saw some topics about the firmware, I did't touch it, should I ?

Currently I'm on Venom ROM, it works but no connection. Tell me if you need more information. Thank you for your help.

PC Internet connection on Android Phone.

I want to use my computer's broadband internet connection by usb cable on my MOTO E2 (2015) 3G VARIANT, using what is technically called Reverse Tethering.

I am running a PC having these: Windows 7 (32 bit)
RAM= 1GB
HD= 1TB
PC Internet Connection: Broadband (Direct Cable, NO ROUTER)

I am using a device with : Android Lollipop 5.1
NOT ROOTED

NOTE: I have used the app named 'Reverse Tethering NoRoot Free' by Florian Draschbacher available on the Playstore.
I can have an internet connection on my phone (though for only 10 minutes 3 times only) but the connection enables for some apps only. Not for most of the apps except browsers.

Suggest methods requiring no root.
Please suggest some way of enabling full internet connection on the device using my PC broadband connection.
