I tried to unlock my bootloader and my phone is stuck on bootloop - Sony Xperia M

I have tried to re-flash the original ftf file, but I think that I had forgot my "USB debugging" option disabled before unlocking my bootloader... I do not really know wtf is really going on... Any help?

I don't think usb debugging is necessary if you select flash mode. Just check that drivers are installed in pc properly or not.

They are installed properly! I have fixed again my phone from bootloop when I was trying to install CWM with the same ftf that I am trying right now but it does not work this time

It surely is a problem with pc. Try using your friend's pc.
One another thing, can you enter fastboot mode?
Type fastboot devices in cmd while connecting your phone with vol- button.

Are you sure you have all the correct drivers installed?
yes, but connect the USB did not prompt new hardware
No Worries...
You have me here,
first you should have ADB installed (adb package including fastboot)
second you should have SEUS (sony Ericsson Update service) and in some cases instead of SEUS you may have SE pc suite.
Turn off your phone,after 10 seconds turn it on again and connect the USB cable while holding back key.
simply extract adb package somewhere,navigate to that folder via CMD
Type:
fastboot devices
now there should be a connected device...:good:

You can't get into fastboot mode if your bootloader is locked.
Try doing a little searching in these forums. These questions have been asked and answered many times before.

He speaks the truth! Also, if youre simlocked too than theres no way to unlock for free. If youre not simlocked and youre not CDMA then you can just go on sonys site to unlock your bootloader. Otherwise you need to get your bootloader unlocked, which will run you ~$24, just use the goog.

To enable USB debugging, go to settings>about phone>tap on the build number 7 times. It will tell you "you are now a developer" and your will have USB debugging back
As far as your driver issues go, it sounds like you only installed fastboot drivers and not the regular drivers. Or somehow the regular drivers got deleted. If it was me, I would try rebooting my computer and phone. If that doesn't work, run the driver setup wizard in the Galaxy Nexus Toolkit. The first part of that process is deleting old drivers. It does a very thorough walkthrough on how to do that.

Try connecting your GNex to PC while in recovery mode then use ADB to push any ROM from PC to your /sdcard/ of your GNex in order to flash it.
At worst case, I think you can use a fastboot image to flash your GNex via fastboot.

Now i running nothing, pratically i formatted all internal data because i would use the 4.2.1 version that is on my pc, after the format the computer does not recognize my cellular phone, so atm i don't have any rom on my phone and now i don't know how i can solve that, it could be easy if i can browse the phone on computer

[Q] Can Not get ADB and Fastboot drivers to install

Windows 7 x64
Galaxy Nexus i515, BROKEN SCREEN, USB DEBUGGING WAS NOT TURNED ON. The phone is completely stock I just turned it on and used it until I broke my screen. Screen lock is on.
I have been trying to access my phone, using Fastboot, to wipe it before I send it in for warranty. I can not seem to do this at all. It seems that I can not install the drivers because I have not enabled USB debugging. Is this true? I have been following this guide : http://www.teamandroid.com/2012/07/30/how-to-set-up-adb-fastboot-with-android-sdk/2/ When i go to manually install the drivers, from SDK, I get, "The folder you specified does not contain a compatible software driver for your device. If the folder contains a driver, make sure that it is designed to work with Windows for x6-based systems." I then tried the driver from Samsung and got the same response.
So then I hold VOL+ _ VOL- and Power and tried to install the drivers for Fastboot with the same outcome as above. Also when I boot in Fastboot mode the drivers that are installed make my phone a modem. The driver is called, "SAMSUNG Mobile USB Modem." I can not get this to change.
So to summarize I can not get the ADB Drivers to install, because I do not have USB Debugging enabled, that in return will not allow me to install Fastboot Drivers because when I plug the phone in the computer sees it as a Modem.
Any suggestions? I am just trying to erase the info on my phone I have given up all hope of recovering any data.
Thanks,
qualm

I meant a screen pattern lock. When you wake up the screen you have to connect the dots in a certain pattern before your screen unlocks and you can use the phone.
As far as, USB debugging drivers/interface having nothing to do with fastboot drivers/interface, then what am I doing wrong? I can not get my computer to see my phone as an android device.

I know what a screen pattern lock is.
Uninstall all drivers, reboot pc.
Assuming device is off: press power+vol up+vol down, until you feel the vibration. Wait 2 secs or so. Device will be in fastboot mode.
Read this thread, i say again, READ this thread, obviously start with the first post! - http://forum.xda-developers.com/showthread.php?t=1812959
Thanks for the link. I read it and followed instructions for installing the drivers. Here is what I did:
1.Uninstalled all drivers
2.Rebooted my PC
3.Downloaded these Drivers, as suggested: http://forum.xda-developers.com/showthread.php?t=1379875
4.Followed these instructions, on how to install the driver without windows trying to find one automatically: http://forum.xda-developers.com/showpost.php?p=29044502&postcount=735
Everything seemed to go well under the Device Manager, when I plug my phone in in fastboot mode, it shows Android Phone -> Samsung Android Interface. This is way better than what I had before, when it was showing up as a Modem. Now when I try to use fastboot.exe and I type "fastboot devices" nothing shows up. I reset the computer and replugged in my device, in fastboot, and the same thing nothing shows up in fastboot.
Thanks for you help.

Not sure if I understand what your asking.
I followed all of the steps here: http://forum.xda-developers.com/showpost.php?p=29044502&postcount=735 I connected the phone booted normally and let windows find a driver so that the driver reads Portable Devices -> Galaxy Nexus. Then I unplugged the Nexus and booted it in fastboot mode and plugged it in. Next I followed the directions to install the Universal_Naked_Driver, in fastboot mode. I can not install the driver for ADB because I can not enable USB Debugging with my broken screen.
Thanks Again.

W8 a sec, do you even have your bootloader unlocked???
You said you're running stock, so that should have been my first question, because to unlock your bootloader through the usual way, you need to confirm a dialog on the device... which in your case, doesn't have a working screen.

3)
NOTE:
- The method described here can be used to install the "Samsung Galaxy Nexus ADB Interface" driver as well as the "Samsung Galaxy Nexus Bootloader Interface" driver.
- Differences between the two procedures. One is done with the phone booted up normally and "USB Debugging" is enabled, and the other is done when the phone is in fastboot. I will cover the "USB Debugging" part here.

We will now install the two drivers that efrant talked about in his post.
A) (FOR ADB - WHEN RUNNING ANDROID OS):
Enable USB debugging on your device
- Goto Settings > Developer Options > Check "USB Debugging"
- Connect device, manually update driver to Naked driver by 1wayjohny, done. On 4.2 and above, you'll need to confirm that you accept the host's (your pc) RSA key.
B) (FOR FASTBOOT - WHEN RUNNING FASTBOOT MODE)
boot into fastboot mode - power off phone and hold vol up + vol down + power
Click to expand...
Click to collapse
Both for A) and B), you need to do the "Update drivers manually" part!
Right now, your only option is B), that is to use fastboot to either:
- Flash stock images.
- To get your data back, boot a custom recovery (which won't require the RSA key confirmation for ADB) from fastboot, then use ADB to pull your /sdcard/ or whatever.

I am learning this ^. I am having trouble getting my computer to see my phone, in fastboot mode. All of the instructions that I have read start with installing drivers for ADB, which requires the phone to be USB debugging mode, and then the drivers for fastboot. So I thought my trouble was, since I can not install the drivers for ADB, and that I was having trouble with all of my drivers, that it was probably the fact that my phone can not be put into USB debugging mode. I now realize that USB debugging has nothing to do with fastboot, as fastboot is before the OS is booted. I am still just having trouble with my fastboot driver and seeing my phone with fastboot.exe.

My galaxy C5 is also not recognized as a bootloader interface while in fastboot mode, after installing all the drivers correctly. Samsung usb driver v1.5.63.0 makes the changes i think, and it makes it as a modem instead of bootloader. maybe the solution is i have to manually update the driver of that modem into bootloader, right click on the modem in device manager and change it's driver into bootloader of your phone, maybe it works. I will try it this way.
Let me know if this solution has worked for someone.

[Q] Qhsusb mode when try Fastboot mode Xperia S

I was trying to unlock my boot loader of my Xperia S. And everthing was ok.
But when I try to connect my phone on fastboot mode (connecting the USB while volume(+) is pressed) the computer recognize the device immediately how "qhsusb_dload". When disconnect the device after that, the phone only turn on with Power and Volumen(+) keys. After that, the phone still working ok, the problem only is present when try to connect to Fastboot mode. As extra information, I can connect the phone in download mode (connecting the USB while volume(-) is pressed) and the computer recognize the device how "S1 boot download".
I'm running on Windows 8.1 pro, also I try on Windows 7 professional, both of 64-bits.
Sorry for bad english, I speak spanish.

If all the checks boxes are ticked, try revoking USB debugging authorizations. Connect your device as MTP (try PTP as well) and try to adb devices again and see if you get the pop up on your phone. Last option would be to boot into recovery via button combo and reboot into the bootloader from there.

Any other ideas? I really need to root my H811. Appreciate any suggestions!

Download mode is not the recovery. If you have TWRP installed as your recovery, power your phone off completely and disconnect it from the computer. Then press and hold volume down and power. Keep holding and when you see the LG screen, release only the power button and press and hold it quickly again (you should still be holding volume down). This'll take you to the factory reset screen, select yes twice and you should be taken to twrp. REMEMBER, ONLY DO THIS IF YOU HAVE TWRP INSTALLED!

I made a tiny progress: I installed LG Bridge software and it updated LG driver on my PC. Now when I connect phone to PC with USB (of course I choose "ALLOW" for popup USB Connection Allow this computer to accept your phone data?). Now I see devices under MTP mode but it is still offline so I cannot boot it into bootloader mode. There is no popup when I run adb devices.
I tried revoke USB auth a couple of time, no luck
Finally I made it work!
The reason is adb I was using is too old
I changed to 1.0.31 then it works w/o any issue.
Thanks for the help all the way! I really appreciate your patience.

I am having a different problem, i get to all these step but when I type fastboot oem unlock it gets stuck at waiting for device no matter how long i let it sit. I know there is no problem with adb because it shows the device with the serial number, I just can't unlock the boot loader
