No, I don't think so.

3784704 - 3670016 = 114,688
114,688 / 1024 = 112
3670016 / 1024 / 32 = 112
3784704 / 3670016 = 1.03125

270336 - 262144 = 8,192
8,192 / 1024 = 8
262144 / 1024 / 32 = 8
270336 / 262144 = 1.03125

29196288 - 28311552 = 884,736
884,736 / 1024 = 864
28311552 / 1024 / 32 = 864
29196288 / 28311552 = 1.03125

1 / (1.03125 - 1) = 32

The image is always the same factor bigger than the device size, 1/32th,
suggesting a consistent overhead in the data format.

Try to find out the block size for the mtd partitions for ​

#flash_erase /dev/mtd0 0 16 - don’t know what number 16 should be for each mtdx 
partition..?

Can someone help me please..??

Is the size where it says ending at 0x0038 so what would the number be for 
it to erase the right amount of memory from the mtd partition..?

mtd0
Block Size 16384,Page Size 512, 00B Size 16
Dumping data starting at 0x and ending at 0x0038...*

I've dealt with this, but in general if people want to modify their list
settings they can + should do so themselves at:

Re: [E3-hacking] Trying to Flashing the backup of the Original Firmware Again

2019-04-15 Thread Nick Griffin 
It looks like when it backs up the NAND its copies the blocks that are bad too 
making the image bigger,  so if you try and restore the E3 back to the way it 
was, you can’t because the bad Blocks stop it from installing,  if you want to 
use Linux on the E3 use it from the Ramdisk in Release V2 
here,Just don’t run 
ams-delta-install then you will not lose the Amstrad E3 Original Firmware. Like 
I did and I am gutted. I have to now buy another one and its going to cost me 
£30 because they are not cheap because they are retro, well…How can it be 
retro when the service only was close 8 years ago. A Commodore 64 or ZX 
Spectrum is retro..

Well it didn’t flash, and I think it didn’t erase too so my code is wrong I 
think… looks like it has bad blocks too and they and made the files bigger in 
size than the partition..???

This process will completely restore your E3's NAND.
This will try and restore The Amstrad firmware on the device. Are you
sure you wish to continue? [y/N]: y
