Installation instructions to fast and safe upgrade your Uboot R55 (or other than R48) to the precious and flashing error free Uboot R48.

Nota Bene: It is assumed that you have already "upgrade" from [R48/Rxx < R55] to R55, probably due to Mitac R65 rom version upgrade.

If not you must first install a R65 rom of Mitac, that corresponds to your device language.

1. Download the Uboot_R55_to_R48_upgrade_tools_by_ansar.zip in a separate directory.

When I tried to upload Total IMG by USB or by SD it gives a MSIPL error and the device not boot anymore...

How can I resolve this???

Hi,

We never flash total image by usb, unless we know what we are doing.

Can your device enter in boot loader menu ?

If yes let me know, if not use jtag or Mio service.

Regards, ansar.

where is the difference between uboot r48 and uboot r55 and why we must
downgrade from r55 to r48? sorry about my poor english!

Hi,

It is trivial to repeat what already said so many times.

Mainly R65 'Locks' the device in order not to accept other than Mitac signed roms.

It is also has bugs that can lead to an improper flashing, i.e. the flashed rom is not as that in the original file.

In any case its up to the user to decide what finally he will do.

Reegards, ansar.
