I have three questions:
1) In the fist part of this post I read: "IT'S NOT REVERSIBLE (YOU CANNOT GO BACK OLD VERSION". Which in my opinion means that after upgrading my TT-RIDER whith bootloader 5.5012 to version 5.5120 its not possible to reinstall the original bootloader 5.5012
However further on in this post I Read that using bootloader 0.0001 .... "Very usefull bootloader to restore an original bootloader". Which in my vision means that after upgrading my TT-RIDERs bootloader from 5.5012 to 5.5120 I can use 0.0001 and then reinstall version 5.012.
Which vision is correct?
2) Is there a possibility to backup the original bootloader?
3) In this post I read: "please update the BL before to use the SD > 2GB". Does this mean that after insertion of an >2Gb-card in my TT-RIDER (with the original bootloader 5.5012 which does not support >2Gb-cards) it will be imposible in the future to upgrade my original bootloader 5.5012 to version 5.5120 in order to enable >2Gb SDHC-cards?
Looking forward to your awnsers
