So hey, my phone (LG d390n F60) started doing weird things since few months ago -- apps started disappearing (music app from google changed to com.google.music and was unable to be launch). Until after shutting down my phone today it wouldn't boot again. There are no signs of booting. When connected to windows computer, Device connected sound plays and it is shown in device manager as "QHSUSB_BULK". Any chance that any of you would know what to do? I was using flashed stock rom. The phone has lost it's warranty so I can't just return it and get new one for free, also can you tell me what the repair of it would cost? Thanks in advance!

Ok, I am new to this so excuse me for any stupid mistakes, please.
So, last night I rooted my optimus one (p500) using z4root. Everything went fine, I got myself a rooted phone and I started messing around. I had no problems till I installed Rom Manager today. It asked me to install ClockWork Mod (something like this), I couldn't find my phone but I selected "Dell Streak" anyway! (I know, it's stupid!)
So, my phone restarts, LG logo comes up and goes and now I'm stuck on a screen that says:
Fastboot mode started
udc_start()
That's it, nothing else, am not able to do anything. What to do now? I've been searching the net for ages now but no help. Please, I need some help. I can't even get a new phone because I'm 15 and my parents won't buy me one! Please, help!!
well, I took it to the LG Service Center and they are gonna replace my phone!! yeii!
Same problem here.
What did you tell the service centre guys?
Did they buy it? Didn't they ask if you'd rooted/messed the phone?
sorry to resurrect an old thread...anyone else experiences this fastboot mode. easy fix. open androidsdk manager and a cmd prompt with admin escalation, then change the prompt to the sdk installed platform-tools directory and run ../tools/fastboot.exe reboot or reboot-bootloader. one of those commands rebooted my phone properly and up to its flaked out rom. which i proceeded to remove and today updated to the latest official stock 2.3.3 for my optimus one.

Hello,
Today I'm totally stressed because since two days, I cannot start my Google Nexus S.
I expose to you my problem :
I had a completely normal Nexus S in which I didn't installed anything wrong, only apps from the android market.
Three days ago my phone rebooted then it get lock on the google logo.
To repair it, I had a look in forums and I find the Odin method.
So I decided to use it and my phone got started normally (I just had a weird problem : I couldn't install several applications from the Android Market which I had before because it was saud "not compatible")
The day after, my Nexus S rebooted once again and then it was locked on the google screen with an open padlock under it
Since that, I think I have attempted everything to reboot it normally
I've tried once again the Odin method but it didn't work
I have installed the clockworkmod recovery but i don't know why I can't access my sd card so i cant install .zip files.
My PC recognize my phone in fastboot mode
My phone is from UK so its a I9020
Now I don't know what to do and I hope somebody will be able to help me and get out of this nightmare
Thank you
Maxime
PS: Sorry for my bad english but I'm french and I don't have a very good level in english
If you were completely stock and did nothing "wrong" (root, flash roms, etc) then you should go back to the store you got it from and they should give you a replacement. That would be my course of action
Have you tried to mount your usb storage via recovery? Then copying a stock rom on there.
Tried to look for missing usb drivers in the hardware manager part of your pc?
I'm not familiar wit return policies in your country, but if everything else fails you can always try to return the phone if it was bought only recently.
Sent from my Nexus S using XDA App
Yes I've tried to mount my usb storage but I can't access it I don't know why
The problem is that I've bought my phone in England and I live in France the models of Nexus S sold in those country are'nt the same and I don't know what they are going to give me if I give them
Can anyone help me ? Please
You're missing the usb driver prolly. Try updating/reinstalling it.
Hi everyone.
First sorry my poor english.
Yesterday I received a phone (LG L4 II E467F Dual SIM) from a customer, the unit was but connecting the loading stopped with the LG logo and stand on this screen. I tried to upgrade the PC Suite, the cell was placed in download mode and the update is performed by the software, download and recording was carried out on the device during the recording process progress was up to 94% with the power on, when he got 95% the device was turned off automatically (A device's battery was at about 70% during the process), then the process has reached 100% normally without error messages.
After this the phone turned a brick, does not care, does not vibrate, does not go into download mode, finally does nothing. But noticed that it was shown in Windows Device list without driver. I used a software to install drivers and the device driver has been installed and he was recognized as "USB Port MTK (COM5)."
I watched a few topics about it, but could not properly understand the procedure and I was afraid to end any device recovery chance.

Does anyone know how I can recover the bootloader of the device?
The bootloader is my biggest concern, because if the device start and stop again with LG logo can at least return the device to the customer.

Hello Guys
So i recently purchased a samsung tablet (gt-n8013) it was working fine, i put it to charged came back from work and it wouldn't bootup ,it stuck at the samsung logo..I checked online (google and youtube) and it seems like a common issue with that tablet (thank you samsung), i tried almost everything, hard reset, root the tablet and nothing seems to be working. I also noticed my laptop doesn't recognized the device after i download the latest firmware from samsung,i tried different softwares like Odin or kies none of them wouldn't recognized the device, so it was impossible to root my tablet..i bought a new usb cable and tried the same steps on a different pc still nothing...Its been two weeks now still not working and i don't know what else to do, if anyone ran to the same problem and knows how to fix it ,could you kindly help me resolve this issue or point me out to the right direction PLEASE!!!..Thank you.
Hi, first, please don't make duplicate threads, http://forum.xda-developers.com/postings.php?t=3131512&pollid= We do this on our free time and sometimes it takes us awhile to respond
Your best bet is to ask for help in your device's forum here, http://forum.xda-developers.com/galaxy-note-10-1. But sometimes device's just die. Odin is your best chance to get it working again. With your device booted into download mode and connected to your pc does device manager show anything? Maybe an icon with a yellow exclamation mark.
