      Yes.
      Today this device came to me and I immediately decided to flash to 4.2
      I downloaded the latest firmware from http://www.tronsmart.com/download.aspx
      Put it on a sdcard and start flashing...
      After 3 blue blinks waited 10 minutes. nothing happened...
      Then reboot with reset, again 3 blue blinks, again waited. again nothing. only black screen on TV
      After the next reboot device was brick. On TV Blank.
      stops blinking blue LED when you clamp reset.
      What I would not do

      Then came here. Download bert`s instruction. Download PartitionGuru & HxD.
      (True, I did not understand the instructions as where you want to copy using the hex editor.
      In general, I copied u-boot.bin to root folder and copied all the information from u-boot.bin in top disk sector)
      Then stuck SD in the device. Clamped reset and cheer !!! I again saw 3 blue blinking !!!

      Then again format SD with PartitionGuru and put all firmware (older 4.1) to root folder on SDCard...
      Went smoked , put SD into tronsmart, pull reset, 3 blinking, after ~1 minute on TV I saw yellow color and further start flashing !!!

      Tomorrow may again try to flash 4.2

          i am finely unbricked
          thanks to DavidGT650R

          i took the main board out, to get an easy access to the SD card
          then i hold the SDcard slot to make real good contact
          I kept holding the sd card in fully, and then released the reset button after the 3rd blink

          bytheway without the heatsink the tronsmart getting really hot
          thank you guys... i think we got a good thing going on here

            Interesting! That is the Tronsmart board as I have had mine apart. But yours has a heat sink


            So it appears they have an issue with the SDcard holder! I think I may have the same problem myself but just got lucky one time! Doing the SDcard tests while OS is booted I see issues with mounting the SDcard.

            Tronsmart got a BAD load of China sdcard holders! That is obvious

              that's a heatsink mod i did do myself.
              it does not have a heatsink on the CPU.

              the cpu gets realy hot
              a southbridge heatsink from an old petium2 motherboard just did the trick!

                  Bert! Im glad you got it working again man! I was hoping you hadnt completely given up on it yet haha
                  Im glad i was able to help a little, there is definately an issue with the sd card slot. Im not sure what we can do to make updating easier but doing this every single time for an update is going to be a pain.

                    I wonder if it may be possible to trick the prometheus into reading updates from a usb flash drive instead of the sd card slot. That or another work around of some kind. The sd card slot just seems so unreliable. It seems any time Ive tried to update Ive had issues and I always think Ive bricked it.
                    Maybe they made the card slot too deep or something, I dont really want to de-solder it to try to find out.

                    Finless, you would know better than me if there would be a way to create a work around for this. I think we all got lucky when updating.

                    Once again Bert congrats!!!

                      I do not think that is possible. Drivers are needed up front for USB. SDcard is hooked to the IO channel so the processor itself looks there by design.

                        Well it was worth suggesting I suppose....Hmm....In clockwork recovery or twrp recovery maybe? I cant remember, but do they only read from external sd? Or will they read from internal storage? On all my other android devices, Ive always just downloaded files straight from my device and flashed via CWM recovery.

                        Actually...My Nexus 7 doesnt have an sd card slot, and I use CWM recovery to flash.

                        Do you think we could flash CWM as our recovery, and then flash the updates from there?
                        I assmue we would only need to use the actual update file, and the g-apps update file. Of course this is just a theory Im shooting out in an attempt to make updating easier for all of us.

                          Well... you can bag me doing a ROM. I am now perma bricked.
                          I even tried doing the NAND pin short for DEEP hard brick and no go

                          So... unless Tronsmart tells us how to unbrick these using a flash tool or something, DEAD....

                          Time to move on I think.

                            how did you manage that bud? were you in the middle of updating or something?

                              Yes, I had made my first ROM and went to update. Once again it did not start updating. Turned it off and on and that was it. I cant get the blue blinking LED back even using the recovery procedure that worked before.
