Stuck unlocking my Atrix.

I'm currently attempting to root my atrix but I've come across a problem that I can't seem to be able to solve through googling or otherwise.
I'm using the tutorial stickied on the Atrix homepage labelled [HOWTO MAY16].
I got as far as step 8 and my phone passed the sbf flash using RSD lite but continuing on with the process to step 13 where it is asking me to type "fastboot oem unlock" into cmd I get an error message telling me that cmd is waiting for my device but nothing seems to happen.
I've tried reinstalling drivers (64 bit), restarting computer, restarting phone, trying different leads/usb sockets with no change to my result.
The exact thing that I'm doing with cmd is to navigate to the platform-tools folder, open adb, open flashboot and then attempt fastboot oem unlock.
Additional information:
UK Orange Atrix 4G running 3.4.4
using IHOP sbf file
running windows 7 64-bit, using the 64-bit drivers.

Do you have access to win 7 or xp? Win 8 is really new and possibly that could be the problem. Worth a shot.

Ops, typo. I'm running Windows 7 64-bit. I'll edit my post when xda allows me to.

Unlock
Enter the bootloader program by powering off the phone, Hold the volume down key and the power at the same time. The phone will be in the bootloader program when it powers up, use the volume down key to scroll through bootloader menu options. the second option will be fastboot program. Select the fastboot option with the volume up key, this will enter the fastboot mode of operation. Connect the phone to the PC via USB cable. Enter the directory where the fastboot program resides on the PC. Type the Fastboot oem unlock command. If sucessful a message will display on PC retuned by the phone. Reboot phone and unlocked will display in the upper left corner of the phones display. Continue to follow the original post, flash recovery, root phone, flash custom ROM. Happy Flashing, Enjoy! :fingers-crossed:

I just gave it another try and it gets stuck after I type fast boot oem unlock. I definitely have the right directory but I still get stuck here. Cmd just tells me it's waiting for my device and stops there. I think it's a driver issue after a bit of googling but the official drivers aren't working. This socks.

I had a similar problem with my device not showing up. There wasn't really a big fix for it but I just waited longer before trying to execute the command. I'm not sure if you're experiencing the same thing I did but when it couldn't detect my device it just hadn't been recognized by the computer yet. Make sure your drivers are working (connect usb and select every option on the pull down menu and are sure the device gets installed). After that do the same thing as before for fastboot but make sure you securely plug it in and wait for the computer to detect your phone before you move forward

Bricked nexus 7 please read!

Hi,
I. Have gotten myself into quit a frustrating situation. My nexus 7 was unlocked, rooted and had several different custom roms installed at various times and had never had a problem. But then one time in particular, when trying to flash a rom (which I can't even remember which one it was,) after the rom had "successfully" been flashed, it rebooted to the splash screen, which it stayed at for a very long time; before just turning into a series of flashing vertical lines that never end. I can use the power+vol- method to get to fastboot, but not recovery; it would appear that my recovery has been wiped as I get the same google splash screen loop as when I try to boot. My problem is that nothing I do allows me to successfully connect the device to my pc (w7, 32bit.)
I have uninstalled any conflicting drivers, un/re-installed the proper drivers from like 7 different guides, I have also tried two different nexus root toolkits. I even tried to use a Linux machine to no avail. I have switched USB cables, everything I have tried has not worked. This is by no means my first foray into android devices, I even freshly installed my android SDK and still my computer just fails to recognize the nexus 7 in fastboot mode.
Any tips or advice would be a godsend. Thanks.

This sounds like a issue a few people have been having.. As far as i know as of a week ago there is no solution . You need to flash the boot-loader it sounds like. There is a thread about this. Search for NV FLASH .. OR APX MODE. Sorry for being lazy and not looking for the thread for you..
They may have some things in that thread that you have not tried.

Turn your Nexus off and plug it into your computer. Does your Nexus start charging? A completely bricked Nexus wouldn't charge. If it starts charging, then try turning it on into Fastboot mode.
Sorry, I'm no dev. Just a random thought to try. But if your Nexus can charge you shouldn't be fully bricked, hopefully. At least this is what I think.

When you say your computer fails to recognise the device...
If you open your device manager in Windows and then plug in the nexus 7 in fastboot mode, what happens? Does it show up in the device manager in any category? Even with a yellow exclamation mark or as unknown device?

My bro bricked his N7
He was rooted and unlocked, flashed a rom now it bootloops on the logo. Now when doing adb devices, it doesnt detect the device when in bootloader, went to device manager and shows problem with driver. Tried other drivers but says its up to date. Thing is I just upgared his friends N7 with the same drivers so I know thats not a problem.
It wont go into recovery either. Now when it is bootlooping, the decive is recognised when doing adb devices. So can I flash a factory image when it is bootlooping or does it have to be in fastboot?

TRY THIS
from powered down,
hold VOL- and POWER for ten seconds,. then let go of POWER and still hold down VOL-

Just goes to bootloader?
Edit seems to be working now even though when doing adb devices in fastboot it doesnt list the device id

In fatboot mode you don't have adb access - down load a recovery image and name recovery.img
Hold shift and right click in the folder recovery.img is in
Choose open command here, in cmd type
fastboot devices
If you see your serial number proceed
fastboot flash recovery recovery.img
When finished reboot to recovery and flash rom of choice
ps, you have had to either change your path in enviromental variables to include platform-tools from the sdk or have both fastboot.exe and recovery.img in the same folder that cmd is pointed to

Help required - Bootloader only

Hi Guys/girls
I received my nexus 7 today (its lovely!) and then proceeded to attempt to root it so I can change the dpi etc.
I unlocked the bootloader using the Nexus 7 toolkit and that worked fine.
I then went to do the one click to root/flash etc and then got stuck on downloading boot.img.
After leaving it for a few hours I gave up and the nexus booted straight back into the os.
My next attempt was to root using the su binarys via fastboot. This again failed on sending the file. I also noticed that my device is locked at fastboot mode when the usb cable is plugged in, e.g the up/down doesn't work unless I unplug the cable. I have tried different cables and a different PC!
My next step was then to use the toolkit to reset back to factory incase I had screwed something up, so this deleted the bootloader etc as it should and then froze on sending the .img across.
I now have a un responsive fastboot when usb is plugged in and no recovery or bootable tablet, any hints/solutions?
Thanks

yes, actually : D

if you dont have that one.
pick your device from the list.
install the drivers for your device with device unplugged
make sure the device is fully off
plug in into the computer and hold down the power and volume buttons
windows should pop up saying nexus 7 bootloader driver successfully installed and then you can use the whole fastboot menu thing without a problem and reboot to recovery or whatever.
my suggestion is to install twrp recovery project 2.x.x.x
oh yeah, its a bug with the bootloader that it freezes when you plug the usb cable into the wall or a computer without the proper drivers

you are 100% positive you did EXACTLY what i said?

I have no idea what went wrong
That's the problem with toolkits though. People don't know what they're doing and when something goes wrong you don't know how to fix it!! I understand where toolkits come from, but they are only useful if you know what happens in the background when you click on a button.

I mess with several android and other devices on my notebook..
Doing so i install drivers for them and often have the exact same issue as you are having..
Do a search for a program called usbdview.. Install to your pc..
With the nexus unplugged run the program..Delete everything in the list that you do NOT HAVE plugged into your computer..Especially anything that says ADB.. OR ANDROID..
Plug in the nexus 7 refresh the list.. and delete the entries created for it..
Unplug the nexus .. reboot the pc.. Then download or use the tool kit to install the latest Adb drivers for nexus 7 ..
reboot the pc.. then plug in the nexus ..
After doing the above see if you can now use fastboot/ adb...
The above will insure its not a driver issue.Often computers get usb devices confused and causes them to hang ..
Good Luck

Help with backing up N4 with cracked screen

My Nexus 4 LCD cracked upon impact today and the digitizer is damaged. I want to backup my phone before I repair the LCD, currently it is:
- Rooted
- USB Debugging is enabled from settings
- Device is set as "Camera" and not "MTP"
I want to use the tool http://forum.xda-developers.com/showthread.php?t=2786395
But I cannot tick the box for USB Debugging when using the tool, so I used the following in ADB in Recovery (TWRP)
Adb shell
echo "persist.service.adb.enable=1" >>/system/build.prop
echo "persist.service.debuggable=1" >>/system/build.prop
echo "persist.sys.usb.config=mass_storage,adb" >>/system/build.prop"
reboot

However, the device doesn't show up. In device Manager (Control Panel) and while I'm in recovery I get "mako" with a yellow triangle
for which I cannot install any driver (I downloaded them through SDK).
I think it's a driver issue and I want to get sorted to have access to my phone, any ideas or experiences would be welcome!!
Thanks!

It's probably not showing up because camera is selected instead of MTP, but my question is why do you want to back it up.... just Repair Lcd and it should be just like it was before lcd broke....

I have a business repairing phones.. nothing is going to happen when you disconnect the lcd and reconnect the new lcd... But if your phone has a frame I would Repair the whole frame and lcd together... Its much easier then just repairing the lcd alone

Is your bootloader unlocked? If so flash twrp using fastboot. Then boot into twrp and you'll be able to copy and paste files from your device to your pc. If you can't see anything on your screen it might be a little hit and miss but it should be possible.

You don't need to choose any options (assuming you have one of the newer versions). All you have to do is boot into it. Boot into the bootloader, hit vol down twice and then power. Let it boot and plug your device into your usb cable. The device should show up on your pc.

That's the problem though, I had set it on Camera instead of MTP, so now I only get access to files like DCIM and NOT the rest of the files. Is there any way to circumvent this and have access to all the folders?

Have you tried booting into twrp? Twrp defaults to mtp mode so I don't think it matters what you set the device to.

I got into twrp, but again i had "mako" in the control panel device manager, so neither Camera nor MTP worked BUT then:
- I installed some drivers from the N4 Toolkit, namely the samsung drivers, and they worked. NOT MTP though, I am able to get into recovery and use ADB Pull commands but again for some files transfer is interrupted by "No such file or directory" that cancels the operation - so I need to somehow transfer directories/subdirectories individually..anyone can help out here?
- Other thing, though drivers are now installed correctly now, I still can't get to MTP and I think that might due to the fact that ive enabled USB Debugging. From my experience on N4 and N6 if I disable USB debugging I can use the device as MTP, if I enable it I cannot, I can only use Camera if it is enabled - so second question: can I disable USB Debugging through ADB somehow?
Thank u all!

Ok, I don't know the status of your device. I know with the latest twrp you can boot into it and access your device through mtp. Adb pull is a pita if you don't know the specific location and name of files. Here's what I'd do:
1. Google 15 second adb install xda. That'll install the usb drivers and fastboot with system variables set so you don't need to worry about the path to fastboot.exe.
2. Download the latest twrp image from here http://techerrata.com/browse/twrp2/mako. Rename it twrp for simplicity.
3. Boot into your bootloader and open a command window in the same folder as twrp.img is in.
4. Run the command
fastboot boot twrp.img
5. You'll be booted into twrp and with your device connected to your pc you should see nexus4. From there it is as easy as copying and pasting files from your device to your pc.
When booted into recovery it makes no difference if you have usb debugging checked you not

Nexus 4 - bricked? - TWRP - no OS installed

Hi All,
I bought a Nexus 4 on eBay thinking I could fix it but I am really struggling.
The nexus 4 has TWRP 2.8.6.0 but that is all.
I cannot enable USB debugging as I don't have any rom installed.
I have tried a USB OTG cable with power, but have learned that the phone still cannot output the right power? The light on my usb stick comes on but TWRP does not list any USB OTG.
This phone does not have an SD card slot, so I cannot load anthing this way.
Is it impossible to get this phone working?
Kind Regards,

Have a look at this thread ..
http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312
(Read the thread thoroughly, and take notes, its real easy to get lost in the middle of the procedure and mess it up, and having to start again).
Flashing the stock rom is done entirely via fastboot, so you shouldnt need to worry about adb.
If you can boot into bootloader you should be able to flash stock image, once you get the windows drivers sorted. Luckily I'm on a Mac, so drivers haven't been an issue. I had a similar scenario sometime ago, and after flashing stock, all was good in the world again. I may be wrong, but you'll probably need the latest platform-tools (which contains fastboot) if you're flashing the latest stock images. (Someone correct me if I'm wrong on that one).

This is good information, but I cannot get any further that plugging the phone into the PC, I have tried 4 different usb cables and with them all windows 7 and XP says "unknown device".
I wasn't sent the original cable from the owner which I am asking to do if they have it, but it may be a long shot for them to still have it.
Looks like I need the original usb cable?

I don't think the cable needs to be original, I've used a Motorola cable on my N4 to flash stock, with no problems.
Is the phone in fastboot mode when you connect to pc?
Have you tried these drivers?

I don't think the cable needs to be original, I've used a Motorola cable on my N4 to flash stock, with no problems.
Is the phone in fastboot mode when you connect to pc?
Have you tried these drivers?

For information I am using a cable from a usb cable that came from a Nexus 5.
When the phone is connected to the PC it had an android lying down with an open chest.
When pointing to the android developer sdk drivers as above it does it's usual thing of saying it is already up to date below that still saying unknown device. I'm so frustrated right now.

Can you reboot to the main bootloader screen?
The reason i ask is .. When you see the android lying down is there a list below showing the phone stats? If not, possibly this is why windows is reporting an unknown device.
You should try to get back into fastboot
This has the info to get to bootloader if youre not sure how..

When you're in fastboot, try to connect to pc again.

Underneath the android lying down it has:
FASTBOOT MODE (in red text)
PRODUCT_NAME
HW VERSION
BOOTLOADER VERSION
BASEBAND VERSION
CARRIER INFO
SERIAL NUMBER
SIGNING
SECUREBOOT (in green text - enabled)
LOCK STATE (in red text - unlocked)
Above the android lying down I can use the hardware buttons to toggle between "Start | Restart bootloader | Recovery mode | Power off"
Am I in fastboot?

Sounds like youre in the right mode. The problem would likely be on the pc/driver side.
P.S. in fastboot mode, you only need to use fastboot on pc .

The driver issue is a massive stumbling block.
I'm still not sure if the cable will work.
I understand I can use fastboot after the PC recognises the nexus 4.
I have a Lubuntu PC this may help me but I have no idea where to start in terms of the drivers.

I use a mac, so im no use when it comes to linux variants etc.
Depending on the power of your pc, you could try using a virtual machine (i.e. virtualbox running windows xp if you have xp disk, or even windows 7). Ive done this before on the mac (xp virtual machine) and it works. This way you can install the correct drivers on a fresh install of windows, without messing with the host OS.
Otherwise, best bet is to uninstall any drivers in your current windows, and install divers from google link i posted earlier.

just outta curiosity, when you plug the phone in (in bootloader mode) change dir to the one with fastboot.exe in and type (in command prompt):
fastboot devices
what output do you get?

As in "no devices detected" ...what is the output? Pfffft I tried!

Just to check I am doing it correctly, I launch cmd in windows, change the directory to the location where fastboot is and type "fastboot devices". The result of this is it just gives the directory name again waiting for another command.
I hope I'm not coming across as ungrateful, I assure you this is not the case.
