This backup does not contain your applications, so to reinstall those you need to either reload from store or save the DEB's when you install applications.

The second type of backup is the type taken with BackupMenu or ubiboot maintanance console, which is a snapshot of the filesystem state at the moment it was taken.
This type saves the state exactly as it is, which is a problem if your state is not correct (like on your N9), as if you restore this kind of backup to your device after a reflash, you will get the device back in the (broken/faulty) state it was before

So, if you have a device in a broken/faulty state, you do not want to use the second type of backup.
Thanks, that's what I thought! How to use maintenance console for Backup, can't see it from README?
OK need to flash back to closed mode or no-preserve BUT that will destroy my 5 partitions plus one extended and reduce it to 3 standard, correct?

EDIT: Reason why can't download from Store in Sailfish OS could that be same error in Harmattan OS as with Microsoft Exchange not working?

I believe you missed this ?

--
what I would try is to fully backup (partitioning wise) my working device, then flash there the rootfs, copy that rootfs (p2) via 'dd' to the other device, test. If not working try once more also with /home (p3). Maybe you will loose partitiong table on working device, but this could be restored easily/manually.
If successful restore the working device.

Would it be possible that your kernel partition is smaller than on other devices? I believe that even on MTD there is some flash filesystem that removes damaged flash blocks from use, maybe your kernel partition has been reduced in size?
Could be, I suspect the flash is damaged, it kind of makes sense now with the issues I've had previously with lost data and settings. How do I see the size of the kernel MTD partition? df shows me:

~ # df -h

Here's the output from sfdisk:

Should I repartition it? I'd have to say I've never done that but there's a thread on the topic here that looks helpful:

How do I verify the size of the kernel partition? I've run sfdisk and it shows me:

end: (c,h,s) expected (1023,3,16) found (1023,63,32)

This is right after flashing MOSLO and trying to flash ubiboot. If the flash is damaged, would it help to run a disk check and mark the sectors, then flash again?

p.s. Is there any way to format the output to make it more readable? d.s.

Kernel is not flashed on your mmcblk0 flash, there's a differnt flash filesystem on the device that consists of the parts of device which hold for example the factory calibration data.

The location for kernel is the MTD2 partition of the system NAND.
You can get some information with mtdinfo command, for example on my device it says:
~ # /usr/sbin/mtdinfo -m 2
mtd2
Name: kernel
Type: nand
Eraseblock size: 262144 bytes, 256.0 KiB
Amount of eraseblocks: 64 (16777216 bytes, 16.0 MiB)
Minimum input/output unit size: 4096 bytes
Sub-page size: 1024 bytes
OOB size: 128 bytes
Character device major/minor: 90:4
Bad blocks are allowed: true
Device is writable: true

Looks same on my device.
Had only info from
cat /proc/mtd
which did not reveal size of blocks.
But neither commands will tell us if / how many blocks are 'burnt'?

[OT]sfdisk -d /dev/mmcblk0
will show output more readable[/OT]

Sub-page size: 1024 bytes

mtdinfo for partition 2 shows:

~ # /usr/sbin/mtdinfo -m 2
mtd2
Name: kernel
Type: nand
Eraseblock size: 131072 bytes, 128.0 KiB
Amount of eraseblocks: 64 (8388608 bytes, 8.0 MiB)
Minimum input/output unit size: 2048 bytes
Sub-page size: 512 bytes
OOB size: 64 bytes
Character device major/minor: 90:4
Bad blocks are allowed: true
Device is writable: true


mtd_debug gives me:


~ # /usr/sbin/mtd_debug info /dev/mtd2
mtd.type = MTD_NANDFLASH
mtd.flags = MTD_CAP_NANDFLASH
mtd.size = 8388608 (8M)
mtd.erasesize = 131072 (128K)
mtd.writesize = 2048 (2K)
mtd.oobsize = 64
regions = 0


So it looks like the size is set to 8M. Is this a factory setting or is it set during flashing? Could it be a result of damaged sectors? I've flashed two different variants with the same result:
059H2M6_RM-696 NDT 64GB ROW BLACK
059L7N6_N9 RM-696 Country Variant Sweden SE Black 64GB

If I print the MTD info for Moslo, its size is set to 16M:

~ # /usr/sbin/mtd_debug info /dev/mtd5
mtd.type = MTD_NANDFLASH
mtd.flags = MTD_CAP_NANDFLASH
mtd.size = 16777216 (16M)
mtd.erasesize = 131072 (128K)
mtd.writesize = 2048 (2K)
mtd.oobsize = 64
regions = 0

Hmm, I have exactly double sized mtd2 and mtd5.
So does not look like erase block problems.
Maybe HW revision?
What is yours? (lshal | grep hardware)

Please omit all those echo changes
I tried to apply the correct changes, but Nitdroid still does not boot. The last entries in the Ubiboot log say it correctly loaded the kernel; where would things be logged after that?

When I run flasher, the hardware revision shows 1501:

Device identifier: 357923041815376 (SN: N/A)
Found device RM-696, hardware revision 1501
