Backup Mediatek ROM on a NAND device
Backup Mediatek ROM on a NAND device
(08-01-2019, 08:51 PM)X3non some people might get a funny idea to try flashing preloader to see if it works -- that's what i tried to prevent by mentioning not to flash
anyway i can't seem to get a valid boot.img or recovery.img from within this 256mb file. try reading 0x100000000 (page only)
see if that works without spft throwing out an error.
also try this
in SPft, press (ctrl + alt + v) to enable advanced mode
click Options > option > download >
untick / tick the checkbox beside 'Physical format / readback' (if its ticked then untick it but if its unticked then tick it)
then perform another readback. the same 0x100000000 (page only)

Whichever way I tried I still get the same error after it reads back 128MB.
(09-01-2019, 12:35 AM)isrgish The most i was able to get was 376.53MB
Here is a link to the file Readback Dump 376.53MB
Is there anything else I can try? maybe a different tool?
(11-01-2019, 01:34 AM)isrgish Is there anything you can help me on this I really would like to be able to root the device but don't know of any other way besides getting the boot img through this procedure.
Thank You,
(11-01-2019, 10:08 AM)X3non Still unable to get a valid boot / recovery.img from the last 300mb+ dump. its there but just too many junk data included (a thing with reading from nand storage). I'm still waiting for the second readback file below in italics
BTW have you tried reading firmware using miracle box?
also try this
in SPft, press (ctrl + alt + v) to enable advanced mode
click Options > option > download >
untick / tick the checkbox beside 'Physical format / readback' (if its ticked then untick it but if its unticked then tick it)

As mentioned in a few post back I had tried all the option you mentioned and I was still not able to readback more then the 300+MB even after ticking the Physical Format check box.
I would like to try Miracle Box where can I download it from?

(12-01-2019, 10:11 AM)X3nonHow can I get the 2nd 300+ MB?(11-01-2019, 03:14 PM)isrgish As mentioned in a few post back I had tried all the option you mentioned and I was still not able to readback more then the 300+MB even after ticking the Physical Format check box.

i'm fully aware off that, you provided the first 300mb+ file and i was expecting the second one
(14-01-2019, 11:16 PM)isrgish ...
Just to clarify. I tried both ways with Physical Format check box ticked and with it unticked. Both watys I can't readback more then the 300+ MB.
...
I have also been trying to use Miracle Box but it isn't connecting to my tablet. I installed Virtual Serial Port Driver in order to get past the comport error. But I still can't connect to the tablet. It says Connecting to Phone. Wait.. but seems to get stuck there.[url=https://www.hovatek.com/forum/thread-25428.html][/url]
(15-01-2019, 10:05 AM)X3non you still didn't get the point. in the initial readback you made, there's a whole lot of junk data (common with using SPft to read from nand storage) making it impossible for wwr to get anything good. approx 250mb from that readback is junk data
i need a second readback of the same 300mb plus (with physical checkbox ticked or unticked depending on what it was when you performed the initial readback) to compare
which version of miracle box did you try? , try v2.54 and v2.58
