can access recovery and download but can't be recognized by pc - G2 Q&A, Help & Troubleshooting

Hello,
i was trying to update my phone (G2 D800) to the last snapshot from cyanogenmod, I wiped it, then i connect my otg to install the .zip but it didn't recognize it, weird, then I try to connect it directly to my pc to transfer the files, my pc says "Unknown USB Device (Device Descriptor Request Failed)"
i can access all my files in the phone, nothing from outside, not even adb.
Then i tried with Download Mode, same thing.
tried the unbricking guide where i had to short two capacitors, same again.
Now I'm downloading Ubuntu and then try the other one.
I wanted to ask if anyone knows something about this or is just that my phone died?
Thanks In advance

[Q] TF101 doesn't connect with PC through USB

Hi guys,
After upgrading to ICS I've been unable to connect my pad to the PC. This is usually not a problem, but last night I needed adb to re-root it. Nothing worked, nothing connected. Tried installing drivers and the Asus sync, but no luck.
Is this a known problem? Anyone got a solution? I doubt it's the hardware as I connected a few days before upgrading...
Found a solution. Went into Settings->Storage and turned MTP off and back on.

THANK YOU! Everytime I plug in my ET4G to the dock to charge it that stupid MTP crap always comes up. Had no idea I could disable it. Thanks!
yeah, this doesn't always help... I had the same problem when i first got my TF101, and i tried all the tricks, the one mentioned here with mtp, enabling and desabling debug mode, turning off and on with usb plugged in, and some others i can't remember... nothing.
In case anyone else is looking for the answer and the quick tips don't work, what did it for me was installing Android Revolution HD rom. I've read that this problem could also be bootloader related.
Anyways, cheers.
How to connect an ICS device to your computer
Step 1. Connect device to computer via USB
Step 2. Set USB connection as Media Device (MTP) (p.s. if you use a Mac you need to download Android File Transfer)
Step 3. Disable USB debugging if enabled
I hope this helped.
when you need turn off MTP it mean your computer doesn't have driver.
If you need using MTP go to asus page and download driver. it's easy to install driver ^^...
recently I can't understand why same file but the computer at my office can't install that file instead other computers working normal... maybe my work place using old windows version...
Like I wrote earlier - mine was actually in MTP mode, but I had to switch to camera mode and back to MTP for it to start working. Thanks for the replies, though. Hopefully it will help some other people with the same problems

[Q] I900 is dead ?

Hey guys!
I need yoyr help. My phone was dead since march 11. I don't remember what I'm done with it, but the following symptoms are:
- when I turn on the phone nothing exept Galaxy S GT-I9000 Samsung screen is showed.

Edit:
I plug cable with turning on download mode. Now computer shows: one of your device has malfunction. DM error loop?

yep, I was checked this thing. And this is not helpful. Yes, have few good ideas but for my case... nothing I can use... Main reason: My computer don't show me any alerts or messages after plug in mUSB to phone...
I solved my problem. What I did was to use another PC, then just installed the Samsung drivers, plugged the phone in download mode and the the driver installed OK.
Odin recognised the phone too so I could flash a kernel.
I can't realize why my PC didn't recognize the phone. I tried reinstalling drivers, the android SDK but nothing worked.
Thanks for the answers.

How to Root Zenfone 5 t00J without PC

Hi, I tried to search in Help Forum about my issue, but did not get a thread on the same.
hence starting a new topic, please help me.
My phone doesn't get recognized on PC or Laptop via usb. So I need to root it via app or any method used with Phone.
If there is any, let me know.
I tried KingRoot and Root Zenfone app, didnt worked.
AFAIK, you can't do that. You need to use computer to root it. Is your usb port damaged? Try clean it up first. Or sometimes it could be just Windows driver issue.

Thank you for your reply, USB port of my device is fine; i can see charging is happening. I tried several ports of Lappy, it says USB not recognized.

Try to reinstall drivers, or you can install Asus PCLink (that automatically installs Intel USB drivers).

Did you tried plugging in to another computer to see if it works? Try using different cable that certified for data transfer. Make sure you check "mtp" as your preferred connection method. If computer still says "USB device not recognized", probably your phone usb port might have broken solder connection.

I guess that might be hardware issue as you already installed Asus PCLink on your computer. Did you already tried fastboot mode? Try going into droidboot menu and plug your phone. If it shows up in device manager, then you are all good.
However if it does not work, and if you have a good eyes and basic soldering skill, you might want to disassemble your phone and inspect the USB port solder connections. You might have to replace the bottom board too if you accidentally fried any caps on it.
You can't root your zen5 without pc......
There are 2 methods

Hey sandy, first check your Android Version. If it is 4.3 or lower then you can root without pc. But if you have an android version higher than that then you will need a pc.
To root without pc:
You can do a simple search on youtube as I already upgraded my Android Version
To root with pc:
Use a reliable tutorial I myself used on youtube:
As I am a new member i cannot give the link but the name of the youtuber is Silicon Rodent
Best of luck:good:

Oneplus 2 no OS installed

Hey guys,
Earlier today I wiped my phone while trying to update the system, but when I tried to install the update it failed. That means that I'm now sitting without an OS on my phone, only able to access TWRP Recovery and Fastboot. I've successfully installed adb drivers and all of that, but when connecting the phone to a computer ADB doesn't find any devices and device manager only sees it as an unknown USB device (Device Descriptor Request Failed). I have been seaching for a couple of hours now and have not been able to find anything that works, so I'm hoping that you guys can help.

When I try to update the driver, as it says in step A-7, the only unknown device is the unknown usb device and when I try to update that one with the qc folder, it just says that Windows have determined that it is up to date?

Have you tried connecting to PC while in TWRP recovery ? You should be able to access internal storage using mtp. Then you can copy another rom & flash it.
I have tried connecting to Windows 8.1 on a Macbook Pro while in TWRP Recovery, and that's where it said it was an unknown USB device.

Any other ideas, because I do not own any other USB type C cables. The one I'm using is the one that came with the phone, but I have never had any issues with it.

Lets try installing the drivers again. If this doesn't work, then it should be a cable issue OR usb port issue. Try this on another pc.
1. Download Oneplus2 USB drivers -> https://www.androidfilehost.com/?fid=24052804347833370
2. Before installing the drivers, Disable Driver Signature Enforcement. -> https://www.youtube.com/watch?v=NM1MN8QZhnk
3. Install the drivers & Restart.
4. Now try either connecting to pc while in TWRP or fastboot.
you can flash factory image through fastboot

Maybe this is a bit annoying but the best solution is to buy another cable since a few weeks ago I had the same problem, bought a new cable and the problem was solved. Hope this helps
Then flash the OS through TWRP using the advanced tool that allows you to sideload files using adb.

How to enter mtp on recovery/fastboot?
I've done the same thing in the past (erase everything) , the solution that worked for me is this:
1.Always have a twrp back up on a usb stick.
2.Buy a cheap usb 2 type c to usb adaptor.
3.Enter twrp and restore the back up.
This way you do not need a pc/drivers etc.
I hope it helps.
