A few days ago, my Razr Maxx HD crashed and won't boot. It is locked, and not rooted. Initially, it wouldn't ever get past the red circle initial splash screen and would stay on that for hours. I was able to press the Power+VolUp+VolDown to get to the menu to Restore, Normal Boot, etc... I was able to get to the dead android guy one time and one time only thus far. I tried to take it into a store, but they did a very half-hearted attempt and trying to get it to work again. Since then, I have never been able to get as far as I did prior in trying to recover anything.
Now, it almost immediately just boots into fastboot with an error of Kernel Boot Failure.
My phone does/did have Developer Options enabled, and I was previously able to use it with Android Studio, and deploy apps to it, so I know the drivers are loaded on my computer fine, and I am using the same cable.
Ultimately and if possible, I am wanting to retrieve the data off the phone. From what I am seeing I THINK it is still possible.
When I connect the phone to my computer, and it is in fastboot, I can type this in the cmd prompt: "fastboot devices". It sees it and lists it as a device. On my phone, I also get the message of "USB connected", or "USB disconnected" (if I disconnect it). In the Windows Device Manager, when I plug it in, it detects the hardware change, and I get the entry for "ADB" in the Device Manager. If I disconnect it, it goes away. So, windows does see it on some level. In that same command prompt, if I type "adb devices", it does not see any devices attached.
If I can get adb to work, I should be able to pull the data off. Knowing that it goes into boot failure, should adb even work? Does it need to boot up far enough for adb to work, or should adb work no matter what?
I've looked into unlocking to install TWRP or similar, but doing so, deletes data which defeats the purpose in all of this.
I can still get to the menu to boot into Normal, Recovery, BP Tools, etc... but so far any option I try puts me back into Fastboot.
Any thoughts? Anything for me to try?
