  • u-boot corrupted - Boot only via SD. S905x 8gb/1gb

    I tried all the DTB files with the nand suffix and renamed as dtb.img, but I'm not able to "Install to internal"

    Now the NAND is a Essencore 13t-8gq8t2h5tarc

    I think this is important to know.

    At the end I can flash the unit with the stock firmware.

    I can boot librerlec from SD.

    I cannot install libreelec to the internal memory

    Anything else will corrupt the image.

  • u-boot corrupted - Boot only via SD. S905x 8gb/1gb

    Good news. I was able to get the original firmware directly from the manufacture and I was able to get the unit back and running Android .

    According the different info under about, I can confirm that the build is based on p281-userdebug 7.1.2 NGH47L 20180416.

    The manufacture sent me the firmware, but once unzipped the *.img file was corrupted.

    I then kindly asked again for another upload of the same file and everything worked again

    My question now is...

    While i was running LIBRELEC, i got stuck at this part

    What was wrong?

    At this time, even with the unit fully restored, I'm not able to do

    Code
    installtointernal


    Regards

  • u-boot corrupted - Boot only via SD. S905x 8gb/1gb

    Before flashing the unit, in the normal setting of Android 7.1.2, i could see that the board was a p281.

    Store erase boot is not working, but I'm sure with few more answers, we will be able to get this unit back !

    Quote from SEIKT

    Have you attempted to flash a ROM via USB Burning Tool with "erase flash" unchecked?

    Yes, erase flash unchecked.

    It will stop at 7% no matter what I do

    Quote from bumerc

    KernelPanic

    Before we move on, please remove the heatsink from the processor and check the exact type of CPU to avoid suspicion of installing a wrong bootloader.

    Yes, S905X on the PCB

  • u-boot corrupted - Boot only via SD. S905x 8gb/1gb

    Full output and Libreelec is not loading

    I believe there is something fishy going on with the MMC.

    Can I copy directly to the NAND from the SD card?

    Thank you again Bumerc

  • u-boot corrupted - Boot only via SD. S905x 8gb/1gb

    Hello all

    this time I'm really really stuck.

    I have this box:

    http://www.mario-sz.com/product/Priv...e-Q1-905W.html 8gb/1gb

    The website shows that the unit it's running the S905w,but he actual chipset, under the heathsink, it's a S905X

    The print on the PCB shows S905XQ4_V1.0 (Probably 4th quarter , since the date is 2017.11.23)

    The units prior to the incorrect upgrade was running Android 7.x.x and on a P281 board

    I tried several IMG using burning tools, but the flashing procedure, hangs at 7%

    The unit will only go in recovery mode using an SD card with nhg47l/20180313

    I'm not able to apply any update via EXT , either SD or USB.

    I connected at TTL interface to the unit, so I'm able to use the internal software and type commands

    At this point I would like to simply restore the OS to anything more fancy than a black screen.

    I need a file to reinstall the recovery mode and then the OS when the unit is booted from the SD CARD,

    Please check S905X bricked - Pastebin.com for the output

    i believe the u-boot is corrupted and the different partitions broken.

    Thank you in advance
