Well, since MotoActv dont have his own thread, i will post it here,as the title says, i will show you how to unbrick your MotoActv,
This tutorial solves:
- Problems like low battery when the MotoActv wont charge and cause of battery low warning wont let you flash any software via bootloader
- Sometimes not bootable motoactvs
- MotoActv with messed up bootloaders(although in some cases works /mine did worked)
Standart Usb Cable
Micro Usb to Usb Cable
Soldering Iron and Solder Wire
A working/partially working Bootloader
ClearD's Image Flasher
A Rom(you can use any Rom,I will use Dprom)
Disassembly the motoactv
You dont need to disassembly it all, just enough to get to battery wires.
You need to remove the battery
Grab your standart usb cable and cut the end point to expose the 4 wires.
Stripe the black and the red one to expose the inside wire.
Solder the wires to the MotoActv.
Make sure the order is Red (nothing) Black (if you dont understand very well this part check the images bellow)
Apply the alligator clamps, so that the wires dont move during the process of unbricking
Plug the usb cable to the pc and try to turn on the motoactv.
If the screen goes on thats a good sign otherwise you should be worried.
You can now unplug the usb cable from pc and motoactv will shutdown.
Now as you should reallize the usb cable is replacing the battery by powering the motoactv in 5 v.
Grab your micro usb to usb cable and plug the motoactv to the pc normally,
now your final setup should be something like this
This is the most important step
You must plug the standart usb cable (the one you cutted ) to the pc,
and quickly press and hold "volume down" key and "power" key until the display lights up, when it does release both keys.
Now MotoActv should be in a menu like this.
It's called fastboot mode or in bootloader menu.
Now you can open the clearD's image flasher put your images in images folder and flash it.
Now the final step is assemble it all and ressolder the battery
