[Q] MTP issue:( - LG Optimus 4X HD

Right, up until today when I flashed Molten Motherboard as I wanted Android 5, MTP worked fine (yet slow, ew). but now, when I plug my USB in, Windows (8.1) detects it, listing it as MTP device an whatnot in DevManager, but I dont get the option to access the storage in Computer. Drivers are installed correctly and everything, it worked after i installed Lollipop, but only once.
Any help? Was considering using EternityKernal for the OTG option as I have a duel memory stick i could just transfer things that way, but I dont htink its compatile with lollipop and I cant find a link for it. I want to stay away form using stuff like AirDroid, but that will be my last resort. Thanks

[SOLVED] N1 Brick

Question...
Just upgraded my primary comp and i wanted to mount my Nexus one to try a new kernel.
I plugin the cable but all that happends is that it charges the found, i have no option to mount?
So i look under usb devices at my computer and finds out that it has a "Windows error code 43".
I try and connect it to another computer, its the same.
I just bought 2 new cables, same problem.
OS: Windows 7 64 bit
My Nexus is listed as "Unknown Device" with no option to install the x64 driver.
So my question is... did i brick my N1 so i'm not able to mount it anymore?
__________________________________________
Update:
I sent the device into HTC' repair center, my phone had a Unlocked Bootloader.
Received the phone back today, it had the bootloader locked again and when i turned it on "Update detected" then i got Android 2.2 FRF91 YAY!
Right click on unknown device and select update driver. Then select the appropriate driver either from the SDK or the Android website. It's been discussed multiple times. Search the stickies.
Also if you bricked your phone, you'd be freaking out alot more.
I did -.- I have installed this driver alot of times, and as i wrote, i already tried the x64 driver.
Windows tells me the best suitable driver is installed, which is Unknown device.
I even tried removing all usb drivers to let it search again, i tried adding the driver manually, also failed.
I tried the driver from the SDK and using search/google i was able to find a x64 usb driver, which also fails. Windows error code 43.

Believe me, i am freaked out :/
I have been developing a android app on my laptop for about 2-3 weeks now, and i wanted to mount my phone at my stationary pc.. Now i cannot mount it on either my laptop (with all the drivers installed) or on my stationary pc :/
Here you can see what it looks like
Note: It does not accept any of the drivers posted in the USB Driver topic

Nope... I just installed Windows 7 32-bit, the same issue.
All i get when i try the drivers are:
"Windows has determined the driver software for your device is up to date.
Unknown device."
You may want to try a live thumbdrive with ubuntu 10. That worked for my 64bit system. Also you can boot your phone right?
Bricked generally means that you can not turn on your phone, thus turning it into a useless brick. From what I understand this only happens when you update the radio and remove the battery.
If you have changed your rom previously are you running the Desire rom?
I've been running the Cyanogenmod ROM while ive been developing my android apps.
I have been unable to mount it after i installed my new hardware. I should also say that my comp managed to destroy a USB-stick aswell.
Worked before upgrading comp, now it doesn't.
And yes, i am able to boot up the Nexus
If you can boot into your phone its not 'bricked'. Do you have SD card reader on your laptop or desktop, or another smart phone or device with an Micro SD card slot. If so I'd pop up the SD card and try to read it by itself. If that doesn't work I think its just the card not the phone. If it does then something screwy my have happened to your phone.

My computer also burned out my Cardreader, so that is not a option either.
However i was able to use the MicroSD reader in my laptop.
My SD card works just fine there.
Search for usbdeview, download it , run it and uninstall your htc usb drivers and then reinstall your X64 driver from the sdk. That should solve your problem.
I know this sounds stupid, but are you using a cable to extend the length of your usb? If so, unplug it.. i had the same problems, it was a stupid cable and i was freaking out.
Re: N1 Brick
No, not that either. Also tried formating the SD card, no luck.

It took me a few goes to get Windows to LOAD the correct Driver
Tried, didn't work aswell... However i do have another question for you guys:
My teacher got a HTC Desire, i asked him to try my MicroUSB (original) cable and see if he could mount with it, he couldn't either, only charging like it does on my Nexus.
So i decided to buy another original HTC MicroUSB cable but i had to wait for the shop to receive the cable from HTC.
Meanwhile i bought this cable and tried it with no luck aswell: http://www.av-cables.dk/computer_ka...a_microb/usba_han_microb_han_1_m_1888_da.html - This one didn't work either.
New question:
Does it require a original Nexus One (HTC) MicroSD cable to mount?
I mean, the cable must be broken somehow too since the Desire cant mount using it aswell.
The shop received the cable today and i should pick it up today.

This tells to me you did it wrong. Do not search for drivers, do not let let windows determine anything. Tell it you have disk, navigate to your drivers and install them. Give windows a choice and you'll never get anything done.

[Q] SD Card will not mount to PC

Alright, this is my first post... So a few days ago, my phone wouldn't mount the sd card to the PC through USB. I've googled and looked on here and couldn't find an answer. I've tried formatting my card, resetting my phone and all kinds of crap that didn't work. I have no clue if this is a hardware error or software, but I was in the process of reloading 1.6 and all of that from 1.0, but it also happened when I was still at a stock 1.6, so it has worked before... but not anymore. Any suggestions on what I should do? And I'm sorry if this has been asked before, but I couldn't find what I was looking for.
do you install adb driver? i think you don't install some drivers
Sent from my HTC Hero using XDA Premium App
Do I have to install the whole SDK or can I just install the driver itself, everywhere I go assumes that you already have the SDK installed?
1) adb driver is *not* required, since it uses usb mass storage... NOT ADB!!!
2) The phone doesnt do the mounting. The phone merely provides the "device". The computer is responsible for mounting.
Wondoze? If yes, try LINUX instead. Wondoze does all kinds of unpredictable things (failures). Rule out the phone by proving it is the wondoze.
Okay, but its weird though, it works on my windows, but my girlfriends and my works computers don't let it.... could it be the versions on there or the drivers messed up? But like I said, it works fine on my computer just not others....
Maybe the problem is your usb cable.
Sorry it took so long to get back but I forgot about my post and figured out my problem, it was the rom I was using, because after I flashed several other roms, it never did that anymore with any usb cable....

USB issue

Hi,
I currently encounter a problem with my Optimus 2X.
I can use my usb port to load the phone but when I plug it in a computer (I tried with several computers running XP / seven / ubuntu ... and several cables). But my phone doesn't seems to be recognized by the computers.
I'm running 2.6.32.45 cyanogenmod. I wanted to go back to the original rom but my backup seems corrupted
Does anywone knows how I can go back to the original rom ? (hopping it will fix my usb issue ....)
regards.
Uninstall the old drivers, and download v3.6 from lg's site it has fixed this issue. =P
Sent from my LG-P990
Even if the coputer act like there is nothing plugged ? On several computer I used the phone wasen't recognized as a plugged peripheral (even a usb key).
I had the same problem, v3.5 of lg united driver was cqusing it , when I updated it got fixed just uninstall reboot and install 3.6 worked for a few more peps
Sent from my LG-P990
Thank's a lot it works perfectly !
I now encounter a new problem, when I try to update my phone using the LG software, it stops at about 30% (looks like it's impossible to connect the phone with the software).
Edit -> I've found an old stock rom and installed it on my phone : everything works perfectly thanks a lot !!!
Guys
I'm running CM Nightlies and I can no longer connect my phone to any pc via USB.
Some have said I would have to flash phone back to an original rom in order to fix then flash CM back over it?
Is this really only way as worried will lose all my internal drive stuff.
You can try to change your drivers it works very well !
If you wan to save your stuff without using USB you can use FTP thrue à WIFI to send stuff on your PC.
I got the same problem since about 4 months. When connecting the phone to the computer, no usb icon appears on the notification bar, also there is nothing happening in the device manager on the computer. Charging always works.
This is still confirmed after using different computers, different usb cables, different usb ports, and 4 different versions of the drivers (up to the most recent 3.6 drivers) even it should still show something even with no drivers. This also occurs in "software update" mode.
Also I tried different ways of plugging in the cable on the phone side (slow, fast, with pressure up/down/side).
This is with CM7, CM9alpha, and just for test also with MIUI.
The odd thing is, in this time span, it randomly worked about 4 times in these 4 months. Last time was just after I updated to CM9 alpha it worked the first time I plugged it in (was surprised with that), but it stopped working too.
For me it seems it's something with the usb chip set in the phone.
The problem here is, returning the phone for RMA will cause problems with CM on the phone, as they probably will say it's because of a custom rom, and there is no (easy) way to get stock rom with branding back on the phone (the only one maybe with a nandroid backup of stock from someone else?).
I'm having the same trouble as dedors. Absolutely no USB data connection. Can't get anything going in nvflash, smart flash, recovery, or when running normally. I've tried uninstall and reinstall the drivers, multiple cables, multiple computers, multiple OS including win7 xp and Ubuntu. USB debugging enabled, disabled, wiping the SD cards, trying with no external sd card. The only glimmer I've seen of it working was when I plugged it into my old XP laptop before and it prompted the computer to install a driver for the webcam that I'd mistakenly uninstalled. I tried cleaning out the USB port in case it had a bunch of lint stuck in it and the cable just wasn't sitting properly.
I don't know at what point it stopped working but it has had no serious abuse that could cause any physical damage.
Oddly it still charges just fine.
Can't return for RMA as it's running Cyanogen 9 and I've no easy way to get it back to stock. I also had this problem on Cyanogen 7. I could probably flash a stock rom onto the phone but I wouldn't be able to nvflash the original recovery.
A lot of people seem to have had USB trouble with this phone.
Happy to provide any logs that may help the diagnosis though you may have to explain how I can acquire them as I only know basic flashing.
Sorry for the lengthy first post, trying to be thorough.
Thanks in advance for any help offered.
I can't think of any solution to your problem (in my opinion it seems like a faulty USB port, it seems to be "popular"), but I can suggest you a workaround... it's actually the workaround I've been using cuz I also have trouble with USB... get an SD card and a USB to SD card adapter...
Or that ftp/wireless trick that was mentioned above, I actually don't know how to do this but I would definitely like to
Yeah that does seem to be the case. At least I can still flash roms and so on. So long as it lasts me the rest of the year I don't mind grabbing a new one then.
Anyone who knows about logs for trouble shooting, can you suggest a way that I might try to diagnose the problem. If I can be sure the port is stuffed and nothing I can do will fix it I'm ok with that but I'd like to know whether I should keep looking for solutions or give up on it.
Cheers.
Hello,
I've got a new issue with my phone updating CM10 and today it's impossible to boot.
I've tried to plug it on my computer in order to flash it but got the same probleme as the first post : nothing happened when plugged on my computers.
Does anyone got this 3.6 drivers somewhere ? seems that the new ones from LG didn't works ....
I have the same problem
I how bought my phone (LG P990), 6 months old, used. I come home and try to connect it to the computer and it won't be recognized. Somehow I manage over that code 1809 # * 990 # to enter the menu and play with the ports I was able to connect to the computer and do the official update to 2.3.4. over LG software.Once again, this comp will not recognize phone (only charging), but using code 1809 # * 990 # and tampering on port settings it was able to connect to the computer.
Now after some time do stupidity and Root my mobile phone(SuperOneClick) and install clockwork-5.0.0.3 and via zip CyanogenMod 9. I tried all the ways that exist but pc does not recognize the phone anymore. After some time, the official ICS update is coming, and now that you can not connect the comp how to update mobile phone. I do a recovery back to the official Android 2.3.4 (I had to change the partitions, 2.3.4 and ICS use different sized partitions) and I run a mobile phone that is again official 2.3.4 and try entering the menu (1809 # * 990 #) by tampering with ports settings I tried to make comp to recognize the phone but to no avail. I tried to change the usb cable, use a different USB port on comp but nothing, no response just recharging.
After googling I managed to find recovery from ICS V28g and I managed to install it to have a functional phone. I contacted 2 service both refused to accept phone because rooted. I tried all the tricks without battery holding vol + and - to enter into APX mode, nothing then Power and vol - S / W mode that worked but comp ga would not recognize until now even that does not work (appears LG logo and when S / W should appear then goes off) and all the other tricks that I found on the internet, reinstall the drivers, I do not know what else.
Oh yeah and I noticed entering the settings on mobu System Settings / About Phone / Software Information / Baseband version - unknown

Hi,
I've found an old 3.6 driver, but nothing works even with it ... I think I must change my phone -_-

[Q] Can't connect to PC after flashing newest Asylum ROM

Hey guys, I need your help here. I've just installed the newest Asylum ROM (full wipe) and everything went fine, the phone works fine. Except that I can't connect to a PC (nor my Mac for that matter), neither machine sees the Note as external storage. I've flashed the phone maybe 20 times with different ROMs since I've had it right when they first came out and never had a problem.
Maybe this is something obvious and I'm just being a noob (searched the forums though!), but I have a hunch there's something broken.
Any hints?
thanks a bunch!

I have same problem, but with every rom I installed, I tried with Asylum, Sweet, Superbean, PA, etc etc etc
All the same problem, detects the phone but I can't copy any file, very fustrating, I'm using windows 8 then, and now windows 8.1 and I think thats the problem.
Sometimes works when I connect like a USB Mass storage, not Media, but sometimes don't work both ways
It's a torture to copy files tu mi phone
OK, so I can connect to my Mac using the "Android File Transfer" application, the application sees the phone, so nothing's broken physically. But still the phone refuses to mount to any computer as external storage.
Is this a bug in CM10.1?
On most recent AOSP and CM based roms, the device is mounted as media device, instead of mass storage.
That could be your problem.

Thanks for the hint! I've installed USB switcher now and it works again! I tried this before, but I must have done something wrong at the time.
On a side note, what's the intention behind this 'new' mode as a media device? In my case that was rather no device at all, I don't get it really..

Note 5 (N920I) USB/OTG Issue [No computer will recognise the device]

Ok ladies and gents,
I've been on a mission to root my Note 5 N920I for months now.
My problem is no computer will read/recognise the device. The Mac's seem to not even recognise it's plugged in, with Windows, no matter which driver I install it keeps telling me the "device descriptor failed blah blah blah". I managed to root my S4 very easily on Mac with Jodin3 so I know that it ain't no user error.
I've Googled and Googled ways to root without a computer or installing a custom recovery without root, but from what I understand I can't flash TWRP as recovery without a computer and therefore cannot root without a custom recovery.
I've Googled ways to fix the USB issue by making the xml file and putting it into the correct folder, but for that I need to be rooted. Right?
When she's plugged into a computer with USB debugging on or off nothing comes up in my notifications except for charging. I tried using the toolbox which I found on here (sorry can't remember the name) though it seemed like I was getting close, I couldn't get close enough before my temper got the better off me.
If my memory serves me correctly the OTG function worked when i first got the phone but didn't after the first update. My mate's Note 5 also has the same issue. I Googled it and seemed it was common issue on these phones.
I've tried to learn some Terminal/Command Prompt to see if I can fix it that way through Debian or whatever, only got as far as understanding it, kind of. Big ups to all you coders/programmers out there it really is an artform.
So PLZ PLZ can y'all help me, there has to be a way aside from setting this thing alight and getting a new phone.
My next mission, which I only embarked on a couple nights ago is unbricking my dad's Note 4 (N910G) that just hit the **** one day after spazzing out for a few days then would not turn on. I'm getting close though I haven't put much effort into that yet.
Any advice will be greatly appreciated, thanks in advance. ?
Anyone??

1)First of all have you enabled usb debugging and oem unlocking options enabled from developers options?
2)Install latest usb drivers for your model no on pc, use original usb cable to connect your phone
3) Try different usb hub-ports on your pc, it is recommended to use main-usb port to connect device properly which is mostly located backside of cpu cabinet
4)Does odin recognises ur device? If yes then you can flash twrp and cf autoroot both ( Sometimes Kies or smartswtich like programmes enforces device not be reognised, so uninstall them before trying to connect and flashing thorugh odin)
5)Try to update device drivers manually from Pc's administration
6) Try to connect your phone on another pc running windows and see if it recognises your device or not
I've tried all of that, i have a 09 Macbook Pro hand me down running Yosemite with Windows 8.1 Pro n just put Ubuntu on her today through Parallels. None of which recognise the phone being there.
I've plugged it into 2 HP PC's and both just keep telling "device descriptor failed". They're both kinda old too.
Unless someone has a specific driver they've made or found or could make me?? Clearly I'm a noob.
Closest I've found is https://github.com/452/USBHIDTerminal/wiki/How-to-enable-USB-host-API-support but still need root or system mounted as rw.
Any other ideas? Any ADB codes anyone could help me with ?
