KB900 Tablet MT6580 issues flashing recovery
(25-10-2017, 09:22 PM)triki Hello,
I purchased a KB900 tablet which says it has a MT8752 but after taking the tablet apart and looking at the physical chip, it's actually a MT6580. I follow this site to create a custom CWM recovery(developerswork.github.io/works/GUIDES/AndrodDeviceTree/) and when I try to flash with fastboot then reboot and try to access the new recovery it doesn't load, sits for a minute then loads right into Android. Anyone have any ideas as to what I am doing wrong ? Any hope would be greatly appreciated !
Regards,
triki

Thank you for your reply, I guess the document i followed was incorrect.
(26-10-2017, 06:48 PM)triki Since the tablet will not boot anymore, does this mean I need to JTAG to fix this ?
When I try to flash with Miracle Box I get error "ERR21002.00"
When I try to flash my backup with SP Tools I get the error "Storage mismatch"
Update:
Been working on getting into META-mode, but when I connect the tablet to the PC I see it goes into META-mode as MediaTek USB Port then dissapears and comes back as MediaTek Preloader USB VCOM and just keep cycling between the two drivers. Now sure why this is happening.

1. How did it go from recovery not working (booting straight to Android) to dead? Could you shed more light.
2. The mismatch error you're getting in SP Flash tools means you're either using an incompatible scatter file / rom or wrong flash settings. Could you share a full screenshot of the SP Flash tool error message

1. I created a recovery with this doc(developerswork.github.io/works/GUIDES/AndrodDeviceTree/), and after I flashed it the system booted up fine, but when I went to shut it down manually the entire tablet interface was locked so I hard to hard reset with the button on the side of the tablet, and after that it would not turn on.
After doing a lot of searching I found a tutorial on your site for how to hardwire the device into META-mode. I'm hoping this will allow the device to stay in that mode so I can flash it.
2. Not sure how the scatter file could be incompatible as I pulled it from this device with SP Flash Tool. I will get a screenshot of the errors.
Thank you for your time, much appreciated !
Update: I've added the screenshot as an attachment
I get this error when I open the scatter file I pulled from the device with SPF Tool. So i'm confused as to why it's invalid.
(27-10-2017, 05:06 PM)triki After some playing around, I installed USBView to watch what happens on the USB ports and now the device seems to be staying in META-Mode for a bit longer than it was before, issue is that when i load the scatter file I backed up with SPFTool I get the error:
...
Update:
What I think allowed me to get the tablet to stay in META-MODE was to press the reset button twce. After testing a couple times, when I only press the reset button once and plug in the tablet USB with volume- down it loops between meta-mode and recovery. But if I press the reset button twice, then plug in the tablet with volume- down, it stays in META-MODE for almost a minute.

it seems you are doing somethings wrong.
the name of the scatter file looks wrong, seems like it was renamed.
it seems like you made this backup you are trying to flash using some tool of some sort. if you made this scatter file dump using miracle box, then you'll need to flash it back using miracle box
also rename the scatter file from "scatter-backup.txt" to "MT6580_Android_scatter"
