(Like memory type, screen size and other hardware.) Not being able to flash that is of course a bit of a show stopper for the working of the tablet. <br />Maybe you do have a hardware issue with your flash, or you don't supply the right bct data / right size of the partition.<br /><br />Do you have this problem with all images or only with this one?<br />(When needed I can give you some pointers to some other images that worked for me.)<br /><br />How savvy are you with linux and android? <br /><br />I would advice you to have a look at my other <a href="http://haokof.blogspot.com/2017/04/resurrection-of-lenovo-ideapad-k1.html" rel="nofollow">post here</a> where I struggle my way through the nvflash utility. <br />When you start that with loading the bootloader, binary blob, and ocm setting without the "--go" parameter will the tablet accept further commands. Then you can try to manually erase/ format the BCT partition (Partition 2). Just to check if that is working.<br />By editing the flash.cfg file is it possible to move the BCT partition to a different position in the flash chip; I don't know if this is really working because it can be that the boot loader has a hard coded address for the BCT partition. But it is worth to give it a try.<br /><br />I hope this works for you. Good luck and don't hesitate to ask when you have more questions.Hansanhttps://www.blogger.com/profile/04148517551004023972noreply@blogger.comtag:blogger.com,1999:blog-6814509026843153116.post-52708596542970467402017-04-21T23:56:02.019+02:002017-04-21T23:56:02.019+02:00I kept getting boot loops with any ROM
