Device charging but not detected - LeEco Le Max 2 Questions & Answers

Hey there,
I am trying to setup my Le Max 2, but when i connect it to the laptop, it shows one short vibration followed by a longer one. It is apparently charging, but I have no chance to see it anywhere on my laptop. No notification like you would expect, not visible through explorer, neither in the hardware settings.
Tried another port already. Is it possible I need to connect directly through USB C? Currently I am using an adapter which was sent along with the phone.
Thank you!

[Q] HTC HD2 HELP! Phone does not recognize USB

Today i plugged my phone to the usb cable and instead of getting the usual connection option screen... nothing... The phone charges but no Data transfer. Did hard reset, still nothing.. now im stuck with the old firmware... any help plz?
might be the cable that you're using. i used before a cable that is not the original and the same thing happened to me, i.e. pc cannot recognize device.
Try Settings-->Other-->USB To Pc-->UNCHECK (enable faster data sync) this should help...
cable : original came with the phone (used to work up until b4 yesterday) also tried another micro usb cable that came with me N900 but still nothing.
I did the un-check "enable faster sync" still nothing
Did soft reset, hard reset using volume keys, and factory reset from phone setting itself. still nothing.. the phone charges.. but no data transfer.. its something to do with the phone because i tried multiple PC's the phone doesn't bring up the connection type option page

No harm in checking.Infact i faced similar issue once and the USB2 was disabled.It took me an entire week to diagnose the problem.These PCs have got a mind of their own and do mischievous things on their own without our knowledge.
But since its not working on multiple PCs,i am not sure.We'll hav 2 wait 4 a solution i guess...
hmmmm.. would a full system format and re-install be possible? and would it fix it? (talking bout on the phone)
HELP, HELP
SAME PROBLEM WITH HTC2 T0MOBILE
even on the boot loader screen, it charges but no USB stuck on serial.
even when on sleep mode and plug the cable orange led is on but it didn't wake up for choose (active syn or stoeag memory)
PLEASE HELP
i can do nothing, HSPL or rom upgrade
the cable and the USB drivers are tested more than 100 times
Most horror problems I had with the USB sync have been down to not having the latest version fo Activesync from microsoft. Uninstall the old version thwen reboot - now download the 4.5 version which I think is the newest and last version they made (unless im out of date) and then reboot the machine, then connect up the phone - but not immediately after the machine has booted wait a couple on mins, Windows takes longer than it often appears to be ready to go. One your hard drive led flashing light has settled down it is probably time to try. Then see if it finds all the devices in your phone.
If it doesnt go into the control panel and double click system, hardware tab, then select device manager and see if there are any devices with a yellow sign with a "!" in them. If there are delete them and then unplug the phone and plug it back in again. It might get past some stuck things. If it doesnt see anything new on device manager theres a menu at the top and look for "scan for hardware changes" this gives teh device manager another look at what its got connected.
If that fails open up the USB section under in device manager - its got a little plus next to it, press that plus and it open up all the names of chips you have for your USB control on the pc's motherboard. Write down the numbers and go and get the correct up to date drivers for that type of USB and install them. Then try the process again. Sometimes deleting the USB drivers and just doing a "scan for hardware changes" again, will reset the USB drivers and start things working, however it can get tricky if your using USB mouse and Keyboard to select anything if you delete the USB, because thats what the KM/mouse relies on to control teh machine, so have a PS2 mouse plugged in if you can. If that fails I would suggest reinstalling windows as its probably knackered. It amazing how things start to work wonderfully on a fresh copy of windows.
I have been where you are! And tried every suggestion that was given here. It all came down to the cord. I actually went through 3 different cords before I found one that worked and found that by accident. I bought an external drive and that cord works. For whatever reason, that is the only cord that now works for me. I only use it for data transfers. i use the other cords for charging.

[q]hd2 charges but doesnt connect

i reacently got my 3rd hd2
whenever i plug it into the computer it charges but will not sync or connect via disk drive
i have tried installing the drivers but it says device unplugged even when its not
can someone please help me?
search for the threads 'stuck in car kit mode'. compare the symptoms.
Look in ActiveSync on the device too... Make sure it says "Synchronize all PC's using this connection" in the connections menu is set to USB.
Sounds like a faulty micro USB cable / HD2 female USB port. Try with a different USB cable!
i tried all of this
i think it is stuck in car kit
also when i try and make calls its automatically on speaker?
Opps sorry didn't read in detail.
Have you tried changing this registry key:
\HKLM\System\CurrentControlSet\Keypad\IsCarKitMode=0
At least for me, when set to '1', my dialler turns to landscape mode with speakerphone enabled. Not too sure how this would affect USB settings though.
Update: Check this thread out:
HD2 Stuck in Car Kit Mode
Seems like a faulty microUSB port on your HD2
its strange because im running android on it now and sync etc works fine
its just when its on windows mobile it wont work
i got rid of car mode whenever i hit home with the regedit
thanks
but it still goes to speaker phone whenever i call/someone picks up
how can i change this?

it being a faulty usb shouldnt make it stay in car mode
but i think it is cause it always starts on speaker and if i turn it off when someone picks up it goes back on
the reg worked for getting the navi panel from autostarting and staying
all i need is a reg to stop auto speakerphone
any ideas?

[Q] Recovering pictures/videos from a Droid Razr with a broken screen

My friend dropped his phone and the screen its completely out. He got his phone replaced under warranty but he still has his broken phone with pictures still on it. It doesn't get recognized when I plug it in via USB because USB debugging is off or its set to charge only or something along those lines. Is there a way for me to turn it on or get the files I need? I thought about getting a mini hdmi to hdmi and hooking it into a TV so I can turn USB debugging on but I'd like to try first without spending any cash.
Any ideas?

You obviously already checked whether the pictures were not on his external SD card, right? If so: Mini-HDMI is indeed your best bet. Of the touch screen does not work (and you are desperate) you could try to borrow/buy the dock with USB. The RAZR would make a nice Android TV box
There is an Android remote control app on the Play store, but I don't know how you could install it. Instead of being an app that you run on an Android to control some other device (e.g. a Windows PC), this is to let some other device (usually, but not necessarily, a Windows PC) control what's on the Android.
The only way that I can think that you *might* get this installed is if a DEV in the Development forum might be able to suggest how you could put the APK on your phone's Micro SD Card *plus* the Android equivalent of AutoExex.bat on a PC such that it would execute a routine on next boot to install that APK, suppressing errors (so that you're not stuck with a "do you really want to install this ****? yes/no" dialog that you can't see. The install would not only have to install this APK, but also configure it. This is a huge long shot. I'm way out on a limb, basically making **** up.
Good luck.
===================================
EDIT/NEW: What if you cabled your phone via hdmi to a tv? Wouldn't that let you at least *see* what the phone is outputting? The digitizer might still work well enough to fight your way through an install of the above app?
Search for android screencast. It's a java app for the pc that duplicates the phone screen on the pc.

Nexus 9 with no USB setup? Very confused.

So, I have received a hand-me-down Nexus 9, and I start in on my usual cleanup and setup routine, only to find something very weird- my computer utterly does not notice its existence when I plug in the USB, and the USB settings are missing from their usual spot in the Storage and USB section of settings.
I eventually found the control for USB type in the Developer settings (maybe it moves when you activate those?), but the computer still doesn't know anything's connected.
Things I have confirmed:
Tablet charges fine.
The cord works for file transfer with another device (a Kindle that happened to be around)
I can change to different USB connection types- none of them work.
The computer is COMPLETELY unaware of the tablet- no mysterious entries popping up to indicate missing drivers, nothing.
WTF? I can't do most of the other steps I usually do without at least a little bit of access so I can root the thing and put in a decent recovery. Has anyone else seen something like this? Was there a fix?

Try a different cable.
Boot into bootloader and see if computer sees device there
When you plug your tablet to computer a notification pops up on Nexus 9 (Charging only). Click on it and you will be able to select different connection mode.
If changing that notification mentioned in Post #3 doesn't work, updated the USB drivers in the computer Device Manager while the Nexus 9 is connected.
I had a similar issue with a Nexus 9 I bought on Swappa. I had to wiggle the usb cable, but in my situation the "data" portion of the usb port on the tablet was faulty/damaged (PTP/MTG/OTG failed). It was able to charge without issues, and by wiggling it windows would detect it but fail "usb device malfunctioned".. I ended up returning it to seller.
I've had this happen at times (only owner of my device). If you did what maelfilk suggested and no go, you either have a power-only cable (similar to what clockcycle posted) or you need to go through process of upgrading driver on PC; or, if that doesn't work, delete everything related to android USB drivers on PC. Then, let them (each device) repopulate.

Screen android phone broken, no USB debugging on, mouse working no visual

Hi guys,
My screen recently died. Before fixing it at a specialized shop, I want to retrieve the data from the phone. Sadly the phone is pattern-locked and until I unlock it I can't access the data when I connect it to my PC. The screen is essentially dead. The image is almost totally black except for small layer in left top corner and the touch sensor is unresponsive, but other than that the phone works and receives notifications and so on.
USB Debugging mode isn't active on the phone and thus I can't replicate the screen of the phone on my PC through software alone, when I connect it via micro-USB. I also didn't think of this problem in advance and I'm not registered on Sony's FindMyMobile or any similar apps.
I tried using a HDMI-MHL adapter and I confirmed that the phone is indeed working because I'm able to get the phone screen's image on my TV. The problem is I can't actually interact with the phone because as I said earlier the touch sensor is not working.
The HDMI-MHL adapter I've used also seems to have a micro-USB port but that seems to work for power only. If I connect a USB-OTG cable on it and connect a USB mouse to it I get image but no mouse. If I connect the USB-OTG and the mouse, alone, I get a mouse cursor but I can't see what I'm doing (phone vibrates as I 'try' and draw the unlock-pattern blindly).
So, Sony Xperia Z3 Compact screen is dead, I wanna connect my Xperia to my TV via HDMI AND use a mouse at the same time to control my phone. Is this possible_
I also thought of another option... go to recovery mode and flash a zip that removes lock. I thought of trying step by step (switch keyboard and TV al the time just to get at point where I can find zip file and flash it). Unfortunately in recovery mode the phone does not allow to stream to TV. It only works when phone is after SIM lock.
Two additions: by removing and re-installing ADB on my laptop my phone is unauthorized. Only a matter of clicking on yes/allow on phone but that's not possible and TWRP 3.1.1-0 is installed.
Anyone any clue? I know I ask a lot but I'm searching the internetz for 2 days now and I'm devistated.
THNX a great bunch!!!
ciao

PS Copy/paste a part of the text from a guy from the internet who had exactly the same problem as I did but his thread ended a few months ago without result.
Just 30 minutes after my post I magically had all the dots correct and that blind!!! So turned on USB debugging and got rid of lock pattern. It was a nice three days of my life Guess there was no solution than getting lucky like I did or screen replacement and getting all your data removed.
ciao
