[Q] Please help,urgent...my optimus cant detect sdcard and usb connection

please help me,after i do app2sd,my phone restart,i tought the app2sd was sucess,but after that my phone cant read the sdcard,i've tried to replace the sdcard with other sdcard,but it still cant detect the sdcard...
and then i think maybe if i flash it,it will recover,but when i connect my phone to my pc,it only charges but my phone cant detect the usb connection...
i've tried to hard reset it,but its still the same...
can somebody tell me what to do?
thanks and sorry if my english is bad

Go to device manager and deactivate LGE Virtual Modem and try to see if your computer recognize the phone

Same damn thing happened to me after trying to install app2sd. i enable usb debugging but i dont get a response in the notifacation bar to say its active. I tried to reflash with the baltic firmware but the KDZ_FW_UPD.exe doesn't see my device (i know i've got the right drivers installed btw). I also can't download any apps from the marketplace over wifi or mobile network(which i don't think is working either).i disabled the lge modem and it still doesn't recognise it. HELP, PLEASE.

Which version of windows are you using?
Try put your phone into download recovery mode, then go to KDZ update tool and select emergency from the drop down box at the top right of the window.
Now flash the rom and it should work.

Jesus H. Christ that was a quick reply, thanks. I'm running win 7 and i'm still a bit of a noob, how do i put the phone into recovery?

Hey, got mine sorted out, you need to deactivate the LG modem in device manager first then put your phone into download mode ( hold vol down as you power up the device and you should see DOWNLOAD MODE ). Then just reflash with KDZ update tool. The percentage bar never moved from 0 for me but , after about 15 mins, my phone rebooted i just unplugged and everything seems ok. The phone mounted the sd card and usb debugging now shows in the notification area.
P.S.
You may have to enable mass storage on the phone for this to work just can't remember if i did or not so try it both ways i.e. turn on mass storage and try flash and if that doesn't work turn it off and try again.
Hope this helps.

Oh, and a big thanks to 'flyboyovyick' for his help on this, Cheers man.

Seems like the EFS partition is broken (IMEI Invalid)
If You don't have any backups done by custom recovery, well... You're probably done.

I am having a similar problem. After enabling KNOX, which I thought was just another antivirus, my phone rebooted, and just got stuck. It would go to the boot page, with the name, and then it would act like it was gonna go to my home screen, but the screen would go black and it would start over. I cleared the cache and factory wiped it, but still no luck. I didn't enable usb debugging, and from what I know there is no way to enable it. I need it to use odin to flash a rom and start over. any suggestions?

Does your device start at all or not? if it starts tell me what do you see? Is the battery charged, anden have you tried Odin 1.87, and have you tired to flash repair firmware 4.4.4, please Try it and make sure to only flash BL file first.

Hey, thank you for the help!
It starts and it doesn't! With the battery, after I try to turn on, it keeps blinking repeatedly and stops only if I remove the battery. And my issue with any fix that I try to flash is that the computer doesn't recognize, probably cuz the blinking blue light is just a random light and not the phone actually trying to turn on... so Odin, for example, doesn't catch any device!
Is there any way to make the computer recognize it? I already tried some usb drivers, but nothing so far... BTW, I have a windows 10.
Thanks!

Well Windows 10 64bit has been creating problems for many many people in the forum and I have seen people running vm and win 7 for the best results. And something very important I must say is that, most of the new computers do have USB 2.0 ports but they are limited in number, so you should find one on ur PC, to us it specifically for phone tweaking softwares. I would suggest you find another PC or laptop around,

Without recovery or Download mode, you'll need to take it to someone with a black box or jtag.

If you can access a working phone of your same model, you can boot download mode from sd

First person with that problem :laugh:
Sorry but that really gave me a giggle. That's what I think when my drivers won't install. Drivers are a headache, you need a lot of patience with this.
Go to the back to stock thread and download the LGUnitedmobile drivers.
Install them and then try connecting in download mode again.
It doesn't always work straight away, keep trying until windows accepts them.
The fact that your phone is charging is a good sign. Good luck

Have you tried pdanet drivers? They work well.
You need to delete the lg drivers from device manager.
Then install pdanet and reboot your pc.
Try connecting that way.

frp locked & usb not recognized

somedays ago, i rooted my samsung galaxy grand prime (sm-g531f). which is processed by flash twrp via odin, & then flash supersu via twrp recovery.
after root, i erroneously add google account, so that frp lock was on. and top of that when i go to recovery mode its shown "custom binary blocked by frp".
so, solve this problem (bcoz i already solve this many time on many phone), i go to download mode, and i try to connect my phone via usb cable in pc, but everytime it say "usb device not recognized", but when my phone was switched on (before locked by frp), it also not recognized by usb but it was charging..
so, now:
*i cant switch on my phone
*cant go to recovery mode
*cant connect by usb cable
*i tried on many usb cables
*two laptops
*install/unistall samsung mobile drivers many times
but, nothing wasnt solved my problem..
if anyone also faced this problem, and solved this, please share your valuable process in this thread.. and help me...
Update-1: now i even change my phone's usb connector if anything could happen, but again my bad luck.. nothing happen, means usb not recognized..
Update-2: sorry i was offline or forgot to update my condition. I was tried to fix it via many mobile hardware technichian. And at last, i fixed my problem by change my whole motherboard. Bcoz, the all technichian told me that, it was my phone's cpu which have problem. For that, it couldn't recognize by any pc.

Do u have another samsung phone? If yes then try this connect that phone to your laptop or pc let it be recognised anf when thatd done removed the port from that phone and immediately connect your phone in download mode. This worked for me. If that doesnt work tell me ill look for another solution

This might be stupid but try it worked for many people. Boot your phone in download mode connect it to your pc open odin and without removing the cable remove the battery of your phone. Your screen wont go off , and if odin recognizes your phone put the battery back. It might not work but still give it a try

I'm having this exact problem also. I've downloaded usb drivers for Samsung, i've downloaded kies, ive tried 5 different computers and 4 different cords. No computer even recognizes it (but it does charge) and only one computer says couldn't recognize usb device.
Currently i'm stuck in the google loop of trying to login with an ID that you've previously used on this device and when i enter in the correct info it just keeps looping back to that screen, so i cant even get into the phone to debug or choose MTP connection etc.
The only reason i pulled out the grand prime and started working on it, was i rooted my s6 and s5 and i wanted to keep learning so i pulled out the grand prime and realized its powerful enough to run updated software so it doesn't have to be a paperweight anymore.

Me too I have same problem bro plz help me

FIX for FRP LOCK USB Not Working
The only way to fix that I have gotten to work is to download the stock firmware and Flash using ODIN. I had to try a few different cords but it will eventually work!! Keep trying!! I did the BL the AP the CSC and the CP, went into download mode and ONLY STOCK FIRMWARE works ok!
