Repacking the firmware with different UBOOT files

[em3ka]

... solution is to repackage the firmware with different UBOOT files to your specific ram MHz device, AtvX most likely wont work for you.

To unpack stock firmware and pull out the files you need Amlogic CustomizationTool. The Ram and Bootloader need to match for firmware to be usable. The stock files to pull from stock firmware:

Code: Select all

aml_sdc_burn.UBOOT
UBOOT.USB
bootloader.PARTITION
DDR.USB

Most Simple solution I could recommend is to Flash stock firmware,
Check both Erase All and Erase Bootloader on stock install,
Then plug in TV make sure box is working then unplug,
Load AtvX LPDDR into Burning Tool,
Only check Erase All,
Not check erase bootloader, that will keep stock Bootloader in place.
Burn img and see if it works.

Erasing stock bootloader causes issues for boxes not tested by developers of ROM, so Burning will use built-in AtvX firmware files "UBOOT" and "bootloader" which may change the RAM MHz speed value too high or too low which will cause box not to boot.
