  • how to Unbrick Mygica Atv1200

    hello!


    I managed to bricuiesc my media player and I try to make the swap to external and internal sd with adb. I mygica atv1200, crashed when I gave the command adb devices, I tried to restart the player, but did not want the power button, I managed to put it out only when I removed the USB cable connected to the laptop. then did not want to light up. I noticed that the front panel lights when connecting the USB cable to the laptop. I have a chance to bring it to life?
    Thank you!

      Hmm.. l got your pm
      Does this mean your unit is working again?
      Do you have root ?
      Can you post your 'vold.fstab' file?
      -or do you know what to edit?
      Try using 'rootexplorer or total commander' on android to make the edit

      I used 'total commander' in the past with success

      Goodluck

              I am happy for nothing, I managed to start in recovery mode I installed the latest firmware and I gave booted restart but crashes and, power does not work, only the usb. I understood everything from electronics is on the software side. What solutions do you have for me?

                          should do the trick

                          Are there any additional steps I need to do except flipping this values? (starting from scratch essentially). I swapped the values and restarted the box. it still shows the internal SD at full (1GB) and the external at ~50gb. This is in the storage section. If I got to something like Root Browser to see the structure the SD card still shows the same old stuff and th external_sdcard shows the actual external. Not sure how to get this to work.

                            Hello Chris,
                            i have exactly the same problem.
                            I have managed to boot in recovery with the recovery sd-card and by disabling the nand-writeprotection. (Look at the attachement)
                            I found out that after deleting the factory_update_param.aml and shortenig the pins, when connected to the terminal, after the first message in the window, open the contact and the box is booting fine.
                            But i have to do this every time when booting, otherwise i get the black screen.
                            I think there is no recovery in mtd, but i dont know how to repair that.
                            I also tried to flash the update_spi_mx_20130805.img from recovery, but abort with an error.
                            Hope you have more luck!
                            Daniel

                              ATV1200 Recovery

                              Hi,

                              For starters i am only able to power the box when i attach the usb serial adapter

                              I've been trying this for ages, i get this:

                              I made a bootable sdcard with SDcardMaker and used spi_MX.bin from firmware
                              When it goes to formatting the card i selected FAT
                              Once all thats done copy the entire contents of the Recovery SDCard folder to the SDCard
                              factory_update_param.ubt
                              recovery.img
                              spi_MX.bin
                              uImage_recovery
                              update_spi_mx_20130805.img
                              update_stvmx_20130805_eng.img

                              Plug SDCard in
                              I needed to bridge these 2 point to enter recovery


                              Attach the serial adapter
                              start up terraterm
                              Hold reset button then Plug power in
                              Press space bar on keyboard to get the box to start up
                              Release reset after 10 seconds
                              Release the bridge once something comes up on tv.
                              I get to recovery and am able to flash update_spi_mx_20130805.img

                              It goes through and finishes and i'm able to use the box but as soon as i unplug the serial adapter i cant power it on

                              I then tries to flash it with the SPI firmware to see if that would fix it but it comes up with error and cant finish

                              Any ideas
