Re: [help] After multiple succesful flashes N900 still crashes during boot
 

Installed easy-debian sulu yesterday and now I'm repartitioning the emmc to your advice of 3 GB, read that quite some times in your postings from the last days. :)
The truecrypt partition is worth a consideration, whats the advantage over image files? Maybe faster read/write speed?

Re: [help] After multiple succesful flashes N900 still crashes during boot
 

Both faster read&write speeds, and security. Especially, on our flash storage medium - due to wear-leveling, file container parts are spread across whole partition, on hardware level. This way, when overwriting (adding or replacing files, copy/paste, changing anything) content of encrypted file container, there is no way to replace old parts with new parts. Basically, you end up in having (physically) parts of new and old container spread over whole partition, which compromise security, if anyone would like to analyze sectors of Your flash storage.

Not to mention, that multiple instances of same container file parts aid in cracking encryption - would be close to impossible in other cases, but with wear-leveling, it's like using same one-time-password for many sessions. And, of course, with file container on wear-leveled flash, You may forget plausible deniability - it's working (partially, excluding only most extreme cases of physical storage analysis) for wear-leveled encrypted partitions, but not for file containers.

Hi, Estel.

I am now under Ubuntu and with repartitioning guide and gparted I will try to repart the memory again. I need just one quick help from you - what kind should be the 3G part for Easy Debian? And all the partitioning guides show that there is one empty "/dev/mmcblk0p4 : start= 0, size= 0, Id= 0" - do I need it?
Thanks

Re: [help] After multiple succesful flashes N900 still crashes during boot
 

I've not had a /dev/mmcblk0p4 partition - just some unused space. I "harvested it" for existing partitions without any issues.

As for filesystem type (cause, I think it's what You mean in your question) for EasyDebian, use one that You fancy - can be ext2, ext3, ext4... Personally, I use ext4, seems to be sanest choice performance-wise. But, remember, that You need kernel-power, cause stock Nokia kernel doesn't have ext4 modules. If You want to keep 1005 compatibility with Nokia Kernel, use ext3. Of course, it can be virtually any filesystem, fiven that you have kernel modules to use it - some people compiled ReiserFS modules for themselves, and use ReiserFS.

BTW, i'm glad to help, but it's 100% off-topic here, so please, post further question about ED (even if it's just about it's dedicated partition) here:

Hello everyone !

I know, it has been a while and I'm not going to restart this thread. I just want to inform, that my n900 is in perfect working order again.

My friend had lost his x6, so I had no means of charging the battery of my phone. I waited for over a month, and now a couple of days ago he finally found the x6. I charged the battery and booted the n900 up while I was preparing the flashing software on my computer. For my surprise, the phone booted to os without any problems, and has worked perfectly ever since.

I still have no idea what was wrong with my phone, but magically a month without electricity seems to have fixed whatever it was.

Anyways, thanks for your advice folks ! :)

Thanks for letting us know how it ended. It's damn strange, I would say - kind of "voodoo programming". Anyway, worth to know. I would probably give my left shoe, for proper "technical" explanation on what exactly happened, and why it is fixed now, as I can't point out any part that could benefit some kind of "deep restart" due to long time without having battery inside N900.
