I tried the unlock several times, and thought it went through.
After flashing cwm img, the phone boots with "security error"
My situation is:
1) phone is not connected via adb.
adb devices return nothing.
2) phone is able to run into s/w upgrade mode.
windows will install drives if I connect the phone in s/w upgrade mode.
3) after driver is installed, From the device manager,
I see the following 3 items,
a. Modems --->>> LGE mobile USB modems,
b. PORTS & LPT --->>> LGE mobile series port (COM11)
c. universal series bus controllers --->>> LGE mobile composite USB devices
4) R & D Test Tools is not working,
IsPhoneConnected always return 0, means phone is not connected.
Any idea or any help ?
I'm really worried of bricking phone.

Don't panic, your phone is soft-brick and it's recoverable. I think your have two options
1. Use LG Mobile Support Tool to recover your phone.
2. Please take a look at this thread http://forum.xda-developers.com/showthread.php?t=2411265
This is great.
I unbrick my cellphone.

when u flashed V20B did u rooted it as well?
I guess it was rooted.
And then I though it was bootloader unlocked. That's why I run into bricking.
Installed fastboot(This is the most important thing I guess), and I'm able to pass oem-unlock now.
It was frustrating but amazing.

Install Samsung Kies to be able your PC to detect your phone via Odin
also check the debugging mode in the developer options

I have uninstalled the older Kies, re installed the latest.
I have installed the lastest odin.
Have tried to link up with and without debugging, odin still does not see phone when in recovery mode.
Only time odin see the phone when phone is in normal mode.
Starting to get annoyed now lol, i cant cut my sim to fit phone, untill this is done
I cant see my s2 on odin either, what am i doing wrong ????
1. Reboot PC
2. Ensure KIES is not running and kill any KIES processes in PC task manager.
3. Download mode
4. Connect USB directly to PC port (no hub)
5. Wait for any drivers to instal or load on PC
6. Start Odin in administrator mode
If still no good;
a) Different USB cable
b) Different PC USB port and wait for drivers

Thanks . Seems that I had been pressing volume up not down.
I have another question . I used chainfire Rom to debrand the phone but keis does not recognize . How can I solve this . Could it be because the phone is rooted ?
i am having this problem at the mo, I have tried all of the above, apart from a different pc.
oden worked fine with my galaxy s2
is there any more updates on how to sort this out please?
thanks

I know this is a 7 day old thread, but I feel for you having been in the same situation. Firstly, have you installed the Android SDK? If not then I advise you to do so. Do a search on how to install the SDK. There maybe smaller downloads available with a package of the binaries you need to do some testing i.e. adb. The instructions will elaborate about how to set up your Environment settings in Windows. Essentially ADB needs to be called from within any part of your Windows system....or else you will have to cd to its location each and every time you want to do something like this. So once you have done that, open command prompt and type adb and see what comes up? If it says bad command or file name it means your environment settings for the ASK are incorrect, if it displays the adb help text in command prompt you are ready to proceed.
When you plug your device in (not in DL or recovery modes) is it detected by the PC? If so then your drivers are probably fine. If not then it maybe 1 of 2 things? 1 the device is detected but the MTP drivers have not been loaded or 2. No detection what so ever and all drivers need to be installed.
To determine how to proceed you will need to do a bit of investigating.
Note the USB drivers are included as part of the Android SDK.
Check in Device manager inside of Windows to see if anything is detected when you plug it in. If so but it has a yellow exclamation ! then it would indicate you need to update your drivers (but not always?). From here you can test to see if the phone is detected and you only need MTP drivers.
If not then I would suggest uninstalling Keis all together and downloading and installing the Samsung USB drivers separately. Install the drivers. Plug in the phone. If it is not detected straight away, then reboot the PC then plug the phone into a different USB port. From here you can determine how to proceed by using adb.
plug your phone in via USB and open command prompt and type this: adb devices
You should see 1 of 2 things.
1) The words "list of devices attached" followed by a 16 digit long ID number a gap and the word "device"
2) just the words "list of devices attached" and then blank and nothing else?
If a device ID is returned then you can proceed with the following. Otherwise you need to do some additional trouble shooting
Proceed here:
Once it is detected by Windows and shows up in Explorer then unplug the phone and go into settings and developer options and check enable USB debugging. Once you have done this it should allow your device to be seen in DL and recovery modes.
Troubleshoot: If not detected try the following:
1) Reboot the PC and plug into a new USB port that you have not previously plugged into.
2) Try disabling USB debugging plugging the device in and then unplugging it and reenabling USB debugging
3) From the status bar try switching modes between MTP and PTP modes. Wait a good minute or so between to allow Windows to detect the driver change. Tip a good indication is your notification tray Icon with green USB disk with a magnifying glass swirling around....Note if you cannot see this at all you probably should drag it into the notification panel so that you CAN!
4) Open up device manager again and ensure no yellow exclamation marks !
Once all this is right and you can get List of devices attached followed by an ID number then you can for sure be able to detect your device from Odin. Make sure you are running Odin 3.04, run it as admin (not necessary but have heard that it helps?)
Good luck

You can try with minimal/no drivers i.e. uninstall kies if you have it and delete the drivers you might have installed on your own-it sounds counter productive but it has worked for me a few times.
You can also try to either install kies or the drivers separately.
Try the forum for your own phone, the people there might know better about this problem.
Also what OS are you on?

Hi all,
Please anyone help me!! I flashed 5.0.1. UB Team Roam few days back. My phone's all data lost I don't know how but it lost and even my phone. I want to downgrade but it even doesn't let me to do it. I can enter recovery mode as well download mode. But my phone is not recognized by windows (Its unknown device in device manager). Whenever I plug usb cable the popup comes that usb device has malfunctioned and windows does not recognize it. I have tried all the possible mathod to get it recognize but I am failing everytime.
I have stock firmware downloaded 4.3 and odin ready but I could not flash it due to the problem. Some one on the XDA told me that the file system of Lollipop is different and that's why I am not able to do so, But I am unable to figure out the problem. Please help and suggest what to do...

Flashing a new rom will not remove old user data unless you formatted it completely.
Odin will work only in download mode and you need to right click > Run as Admin.
Enter download mode on your phone and connect your device to PC then flash the stock 4.3

Use mobile Odin until you get it fixed here >> https://play.google.com/store/apps/details?id=eu.chainfire.mobileodin.pro << this will allow you to flash stock without using a pc.

Thanks for your valueable advice. I will try it today and will be back with result.
I done it but still the phone is not at all recognized
Hello!
I was trying to downgrade a Moto E XT1021 and I don't remember how but I ended with the phone stucked in the "bootloader unlocked" screen.
Tried to access the phone on the fastboot flash mode and I can get into the mode by pushing volume down and power on for a few seconds. The problem is that I'm not able to send command to the phone because adb or fastboot doesn't detect it.
The USB cable seems to be working because on the phone screen you can read USB connected and USB disconnected every time I connect or disconnect the cable.
My guess is that there's a problem with the drivers, I've tried everything, of course installing the MotorolaDeviceManager_2.5.4.exe was the first step and then I ended up trying adb-setup-1.4.3.exe and also adb-setup-1..3.exe with no luck. I'm using Windows 7 professional 64 bits.
Right now phone driver says: Android Composite ADB interface.
Hardware ID is USB\VID_22B8&PID_2E80
If I remove the driver the device with no driver says "fastboot condor S"
I want to install 4.4.4 on that phone.
What can I do?
Thanks!

I really don't know why it worked, but I had several folders with adb, fastboot and firmwares and ona of the folders with fastboot detected the phone, I tried the other folder and that version of fastboot didn't detected the device; really weird.
Same software, same dll's but in different hard drives, the one on the C drive worked and the one in the D drive didn't detect the phone.
As I said, really weird.
Ive been trying to root my device for over a month now, and i havent had any luck. Ive used different USB drivers software and Hardware. Ive used different cords from stock to the ones from my job and friends yet i still have failed to root it. ADB reconizes my device no problem when its booted up, but as soon as i boot into FASTBOOT mode my computer doesnt reconize the device. What am I doing wrong or am I doomed to have an unrooted device?
I had the same issue with windows Vista.
Grab the attached file. Unzip to wherever.
Plug your phone into the pc IN fastboot mode. Open Device Manager.
Find the messed up driver, usually indicated with a yellow symbol in the list.
Right click it and update driver. Don't let it auto search for one. Manually tell it where that driver is that you just unzipped. It will show a list and chose the android bootloader one. It will warn you stating it's not correct, ignore that warning.
If you need more detailed instructions just holla.
Peace.
Did you try fastboot commands when in the bootloader? Remember that adb is only for when the device is booted up normally. Just making sure...
Sent from my LG-H901 using XDA-Developers mobile app
open device manager, you will see the device with the yellow symbol, right click and select update driver software
after browse my computer for driver software --> let me pick from a list of device drivers in my pc --> android adb interface! . click on yes. this worked for me

in ADB with USB-debugging on you can write "adb reboot edl" in command promt and it should make your phone reboot to download mode.
download mode is the screen off and the LED is just blinking red.
Flash with MiFlash the rom you want?
If all drivers are installed on your pc(adb&fastboot) open adb cmd tool and type : Adb reboot edl

I cant because phone isn't recognised from miflash. I can only enter fastboot mode but cant flash with locked bl. :/
Also reboot edl doesnt work because pc doesn't recognise my phone.
it's not clear what "not recognize your phone" looks like, but let's try these simplified steps.
prerequisite: your phone is redmi note 3 pro (qualcomm cpu), windows 64bit, mi flash version 20160401, you've downloaded fastboot ROM.
step 1 install mi flash on your pc
step 2 reboot your pc
step 3 enable usb debugging on your phone
step 4 connect your phone to your pc
step 5 in command windows, run adb devices
step 6 authorize your pc on your phone
step 7 in command windows, run adb reboot edl
step 8 launch miflash
step 9 choose rom
step 10 flash
Check device manager in your pc and report back on whether it shows your phone under portas as Qualcomm 9008 port or 900e port (try and enter edl mode with the button press trick).

By saying my pc doesn't recognise the phone i mean that when i have the device powered on an then connect it to the pc, nothing happens. its like connecting the phone with a usb cable and not connecting the other side with the pc. Like the pc isn't powered on. That's why i can't run adb devices and furthermore reboot edl. Also i can't access usb mode in 6.5.12 stable dev rom, through settings and every app that i checked. Its like the usb mode selector app crashes. sorry for my english... i hope you understand me

while, did you follow what I've written?
or maybe you can try these first: factory reset your phone, then when you connect your phone to pc, you should use the original usb cable coming with your phone, do not use other usb cable even it worked for other phones.
then follow steps I've mentioned.
if successful, after step 7, you should see this in device manager windows.

Thanks for replying. My phone finally decided to be nice and when I connected it to my USB 3.0 port on my laptop and powered it on just installed mtp drivers and finally worked like a charm. It charges it can be recognised by PC. I installed global stable ROM now and I am fine. thanks for your time.
