[Q] WinMo wont connect via USB since new Froyo installed.

I was trying to put the hum/hiss sound fix on my sd card and I cannot get my pc to connect via USB...
My wife has a TP2 and it connects fine...
I have tried with/without the sd card in, rebooted the pc and phone, rebooted the phone while connected to the pc.... nothing...
wtf...
anyone else with this problem?
PS... NRGZ28 had posted a very basic rom for booting to android back in Feb and it is now gone from hotfile. Anyone know of a quick boot into android?

- Try a different computer
- Try a hard reset
That are the first thing you should do.

Tried hard reset...
Dif PC is not an option at the moment... I have rebooted...

Just flashed the ROM (NRGZ newest, thank goodness I had it on my SD card) and I still cant get it to sync...
I have attached the USB error I am getting... (Win7, new install)
The phone is not asking if I want to active sync or use as storage???? wtf...

Reboot your PC? lol bet your tried that already...
Try this:
settings > connections > usb to pc > and disable Faster Data Sync then try. This way uses the generic usb drivers and maybe it will connect.

That did not work...
How do I get my Win7 laptop to see the phone with Android on it?

dont think thats working yet

Ya I don't think that works yet, it's tied to Android software drivers and the use of the USB port, since there is no drivers to control the port only to charge battery. Windows thinks there is something there, but the phones USB can't communicate back....I think this is the issue or at lease after playing around with it on my phone anyway

Not that it's a huge amount of help but might troubleshoot down to the hardware level...if you go into bootloader mode on the phone and connect to USB does it connect?

I don't think you should go that deep and dirty. My touch pro 2 works only with only 1 (non-HTC) cable of the 10 i have at home, all are the "standard" mini-USB but only one works flawlessly for communicating/flashing/syncing, the other cables either do the same error - device not recognized - or windows says that the device could communicate faster - and only copies files slowly.
All in all: you should simply check with another USB cable or if you have the factory HTC cable try it with that. I noticed that the cable i am using other than the HTC one is a very good quality thick (low-resistance and double-shielded) USB cable and it never failed on me.
One other thing you should definitely watch for: plug the USB cable into the motherboard USB port directly (on the back of the PC where you plug the keyboard, mouse etc.), sometimes PC cases with front panel USB outputs simply die, or are wrongly attached to the motherboard USB header and it can cause the aforementioned problems too, not to mention if it is wrongly attached it could harm your phone too.

No usb connection?

Hi everyone,
I'm not sure if it's just me being a noob or if there is something borked on my P6 but I cannot for the life of me get any of my computers to recognise my P6 when I connect it via USB. I have installed the Mobile Drivers and have also tried putting it into USB Debugging mode but the computer doesn't see the phone. It does, however, charge it via USB but I get nothing else saying I'm connected and HiSuite also reports me as not being connected. Any ideas?
Ok, this is solved. Apparently, the phone's USB cable and another that I tried did not work with the phone but I swapped out to a third cable and it works fine.

[Q] Can't connect to the PC

I have had issues connecting the Note 4 to my PCs. I have tried multiple cables and computers. A usb error appears "Usb Device not recognized" "The last USB device you connected to this computer malfunctioned and WIndows does not recognize it." All PC's are running windows 8. I have tried connecting it via fastboot to flash to stock as well as through ADB and I cannot get anything to read the device.

Are you using the oem cable? Sometimes cheap generic cables give errors. Enable usb debugging and see if that helps. Good luck.

Thanks but I've tried multiple. OEM and aftermakert cables. I found that when I put it in the charger it doesn't detect it as AC. I believe for some reason when the phone is connected to the PC it doesn't switch to MTP, which could cause the issue. I have wiped the phone, tried different roms, and installing plasma kernel. I am at my wits end. I have tried finding sprint's seceret number to dial, supposedly there's a menu to force MTP but I can't find it anywhere.

OK. So I couldn't connect via cable I tried flashing the stock image though mobile odin and now I lost recovery and the phone bootloops. Does anyone know a way to boot into recovery from the external SD card?

I would just flash the OF5 tar and start from scratch. http://forum.xda-developers.com/not...om-sm-n910p-stock-of5-odin-flashable-t3158114

Sounds like it's your computer.
Edit: Any other phone's Samsung or not able to connect? Does your phone charge with any or all of your cables? Hopefully the stock cable.

You need to go to Device Manager and Uninstall/reinstall the drivers pertaining to USB
Uninstall the samsung drivers
After that, unplug your powercord from the laptop
connect the phone to your usb port first and then replug your powercord and turn on your laptop
let the usb and samsung drivers reinstall(auto or manual)(if it detects it normally))

I wish I could, the issue is that since I get this USB error, I can't get ODIN to detect my phone.

I was able to get my Note 3 to connect with no problem, I was even able to get ODIN to detect it in Fastboot. I have one more cable I am going to try tonight, I have my girlfriend bringing it with her. I may have switched an S4 cable with the Note 4 cable. I hope this is the case.

I was using my desktop, and I tried this on my laptop. Didn't work. Thanks though! I am wondering if this possibly could be a Windows 8.1 issue...
Anyways, 5.50 to anyone who gets this working.

I accidentally switched cables with my son's s4 and nothing would work. Figured it out and then I could connect to my computer. Could be the same thing lol.

I wish that was the case. I am wondering if it's a windows 8 issue now.

I'm on 8.1 pro, and my devices detects fine under cm12.1.
Have you tried going into Settings > Storage. select the 3 dot menu on the top right and force MTP or PTP detection while device is connected to PC / Laptop?

Zenfone 2 not detected when connected to PC

I was trying to transfer some files to my phone through a USB cable today, but the phone was not recognized by the PC at all (Even though it was working a week or so ago). I had some issues before with the cable needing to be still in a certain position or it would disconnect from the PC, so I tried using another USB cable which didn't work either (I tested both USB cables with another device, and both cables were working and the other device was recognized by the PC).
I also updated the USB drivers on my PC with the official drivers on the ASUS support page, and tried putting my phone in fastboot and recovery mode, but both were still not being recognized by my computer. My phone still charges properly, but I am wondering if the USB port got damaged somehow so that it can't connect to a PC anymore?

uninstall and reinstall the drivers. Ensure that phone is not connected during the process.
also have you upgraded your pc os ? if yes then its a little cumbersome to get the same working...
i changed from stock to cm, it is showing well now ... using RR now

Is your phone encrypted? If so you need to unlock in order for your pc to recognize it.

Thank you both of you for the help, unfortunately, my phone was not encrypted so there was no need to unlock in order for it to be detected. Uninstalling and reinstalling the drivers didn't work, and my PC was already on windows 10 since a few months ago. I would also prefer sticking to the stock ROM for this phone for now since they keep coming out with updates.
In addition, I tried using a USB OTG cable to see if the phone could detect the USB drive and my phone couldn't (it has worked before, and my old Galaxy Nexus could still detect it). I also tried plugging my dualshock 3 into the phone, and it also couldn't be detected (also had worked before).
It looks like it's actually a hardware issue and my only option is to RMA it now. I'll have to do it at a time when I don't need my phone as much or when I am not as busy.
PS: In case anyone else has this issue in the future, quick charging also no longer works

zenfone2 I also experienced that, and I have tried several ways, but remains unchanged. I was dizzy today :crying:

Question Phone not connecting via USB

My first Poco F3 is completely unlocked and running a custom rom, still able to connect to PC even now.
I have a second Poco F3 that I was able to originally connect to my PC to debloat, hadn't needed to connect it to a PC till now. Today was the day I could unlock it but when I connect it via USB cable, original or otherwise, no usb options appear on phone and nothing shows on PC. I can use the same cable on my first Poco F3 and everything works fine. I've tried multiple cables, reinstalling drivers, restarting phone and PC, trying a different PC, enabling debugging tools, etc.
Nothing shows in "My Computer"
Nothing shows in Device Manager
No usb options on phone (default is set to File Transfer)
Nothing shows in CMD with "adb devices"
Charging still works
Is there anything I can do to at the very least unlock the bootloader? Or is this not fixable?

long shot... check the usb C port for dirt/dust/fluff blocking connection...

Most probably u debloated an app responsable for media transfer. If u can, revert what u debloated.

Did a factory reset thinking that may have been the case, still no good.
Tried cleaning out the port and still no good either

I still think it's Windows. Please can you try putting Ubuntu (or another Linux distro) on a USB, booting from that, installing platform tools (ADB/fastboot etc) and then running ADB devices. Windows is very finiky sometimes.
Edit: when you plug in your phone to the PC do you get a notification saying charging? Or is there no notification? Also does it start charging the phone?

There is a delay before it begins charging and the charging animation plays but yes it does. But then there is no usb notification. Will try ubuntu and report back

Booting into Ubuntu, before installing platform tools the first phone that I knew worked showed up and showed up in adb devices when platform tools was used. The second still didn't show up, exactly the same as on windows

Try downloading the installed stock miui rom from the update menu in the miui update menu and re-install it on the phone

Unfortunately reinstalling latest package didn't help

Can't think of anything else to suggest. Sorry

If the usb connection continues to be nonexistent, is there any way to at least unlock the bootloader without using the Xiaomi Unlock tool on the PC?

Are you sure the USB cable you're using support transfert file?

Nope

Hmmmmm.....strange! I'm running out of ideas....try different USB ports on PC. Maybe it's a faulty USB-C port on phone after all.

do you have a type c usb-otg?
If yes then see if it is detected by the phone

Yes. Used 4 different cables, 1 of which is the cable that comes with the phone. None work on this phone but do on the first phone.

Tried different ports across 2 PCs. I'm starting to think it is a faulty port, though it worked fine a week ago.

I honestly don't know if any of my cables are usb-otg, how would I check?

Try to use this version of Mi FLash Tool (only for drivers) : https://xiaomiflashtool.com/download/xiaomi-flash-tool-20210226
Extract and launch the executable then drivers install

Something like this. You can plug in any usb stick and see if it is detected. Another way to check whether the port on the phone is working for data as well

I don't have anything like this but that reminded me of the usb-c to headphone adapter and that also doesn't work. Sound just plays out of the speakers.
Trying with Android Auto in the car, the car doesn't register a device connecting at all either.
Either the data transfer portion is somehow disabled on the device itself (which I would love to know how to enable it again if that's the case) or it's a damaged usb port. Just strange that it worked a week ago.
Something I forgot to mention, when I went to unlock the bootloader yesterday the phone did not show up anywhere except for in the ADBFastbootTools to debloat the software as a OnePlus device but then never showed up again.

I have the same problem, did you solve it ? I replaced the usb board of the phone, still not working.
