Hi folks,<br>
I would strongly support putting a no-way-writable ROM chip as this
first level boot loader. If there is no such option, I really wonder
what is my option if somehow it gets screwed up, other than the trash
can? Is there an always working solution to reset my moko?<br><span class="sg">
