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

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

Chromecast USB OTG Y

Dear XDA Members,
I've a question is it possible to connect the Chromecast with an USB Hard Drive via micro USB OTG Y cabel?

Currently Chromecast can only use USB OTG for firmware flashing. OTG isn't available in the normal booted state.
So if you're asking whether you can connect a USB hard drive on a USB OTG cable connected to Chromecast for playing/accessing stuff on it, No.
If you're trying to use a USB hard drive for FlashCast ROM/mod flashing, I'm not sure if that will work.
In either case, you need a powered OTG cable, as Chromecast does not provide power on the USB - it expects to receive it there.

Ok but did you mean that its impossible to connect an Hard drive to stream an Video from it with flashing the device or without ok without it wont work i know but with an Custom Rom or root ??

You may be able to enable it with a custom kernel.
But even then you'd need a way for playback. you could start a dlna server but in this case doing that with another device would be the same result.

As @m11kkaa said, it might be possible with a custom kernel, but no custom kernel exists AFAIK, and Chromecast is not like a typical Android device which is easy to modify or do custom development for.
Also, even if you got support, you would need a Chromecast-side app that can access the content, and an Android-side app to browse/control it, which seems like a lot of work when you can already achieve the same functionality via DLNA or storage connected to the casting device, rather than storage connected to Chromecast itself.

N900A Can't Connect To PC After Update to 5.0; Lost Root Access

I have a Note 3 which I rooted October 2015. I installed Android 5.0 using safestrap, was on 4.4.2. I had some trouble with getting 5.0 on the phone, but finally managed. Since then I don't have root access as well as no computer will recognize my phone. I have tried updating all the drivers in the world, installing them from kies, samsung website, 3rd party sites. I am convinced that I messed with something when I put 5.0 on the phone and now it no longer is talking to the computer correctly. I saw a thread that mentioned it might be the radio/modem firmware. (I can't seem to find that particular thread) I feel like I'm stuck. I can't flash the modem firmware via the computer because the computer can't see it(tried using odin/minimal adb and fastboot), and I cant flash on phone because it's not rooted. I can't root because the phone the computer doesn't recognize the phone. I've tried several one-click roots to no avail.
To summarize things tried:
Factory Reset
Attempted Root via Computer
Attempted Root via Phone(towelroot,framaroot,kingoroot)
Download any and all drivers that might work(Kies, samsung, 3rd party)
Changing the USB Settings to be AP MTP + ADB
Yelled at it
It's not my first rodeo, but I can't seem to figure this one out. Please help.

Does the phone charge when connected to a power source? Possibly damaged usb port?

The phone does charge. It doesn't seem like it is allowing the fast charge, though.

Maybe the port is damaged? Tried different computers, USB cables, and USB ports?

I've tried different computers, cables and ports. That is part of the reason I narrowed it down to the phone having issues. I'm leaning toward software, but do you have any suggestions for testing the usb port?

Sorry, I don't know of any way to test the port. Replacement USB ports can be had for a low price from ebay.

No USB recognition at all, HELP.!

Hi, firts of all sorry for my english.
My sister give to me a BLU R1 HD 2GB RAM/16 ROM, it come without Amazon ads (so i think its OEM version). Its running BLU_R001UU_V21_GENERIC.
She told me that one day just not was recognized by PC to transfer files,photos, music. I make a wipe from recovery and still the problem no USB detection at all just charging, no sounds like new USB device was conected, no device on Device Manager.( i do this on diferents PC Windows 10, Windows 8, and Linux Elementary OS , Deeping OS)
I enable Developer Options and change MTP/PTP/Only Charge option and nothing happened; I opened the device to check the pins on the USB connector and check continuity and all seem like be perfect.
I thing that may be when was update to the last software something happen and lost USB recoginition, I want to Root the device and change Recovery but i see that the steps need connect the R1 HD to PC and make some things throw ADB console.
My question is: can i downgrade the original rom from SDcard in the actual Recovery.. to try recover the USB functions. or may be its something wrong on any internal chip that no make the USB conection.

I have not seen any other reports of usb dying after OtA update. You say you tried with different PC, what about using different usb cable?
But more bad news for your plans. If you have official v21 update, then you are not rootable anyway.

I have the exact same issue... and it happened just after an OTA Update. After that it showed it was charging only when the phone was shut down.
No USB recognition whatsoever. PC/Mac. Tried several cables.... All USB modes... Factory Reset... Nothing made it work.
I contacted BLU with the issue. As soon as I have an answer (If ever) I will let you know.
If any of you know anything about this please share it here.
Oddly enough, After a cache wipe and factory reset, I have no ads on the lock screen. The app is running on the background but nothing shows up.

I think if we can downgrade to a official rom under the actual recovery maybe that fix the USB. But all methods are under USB connection to PC.

As far as I know downgrading is not possible without making the phone unusable. If by any chance that is possible maybe an update from an SD Card can work.
