09:05 < TheSeven> user890104: success :)
09:08 < user890104> TheSeven: what did you succeded :) the notes installer?
09:08 < TheSeven> yep
09:10 < user890104> is it available for testing, i still have not filled my nano 2g with anything after the wiping and format
09:10 < user890104> so even if something goes wrong, it won't cause any data loss
09:15 < TheSeven> i'll automate the build process, add the rockbox installer, and then commit it to svn
09:17 < user890104> ok, i'll try to figure out how to extend libipodcrypt's functions, and if it is successful i'll post a patch

09:41 < S_a_i_n_t> TheSeven: Congrats?
09:41 < S_a_i_n_t> two installer releases in two weeks? nice ;)
09:41 < TheSeven> well, this one will be really cool :)
09:42 < TheSeven> take a factory-state ipod, copy a file to it, unplug it, wait a bit, and you'll have iloader and rockbox on it :)
09:43 < S_a_i_n_t> what the!?! I understood getting iLoader on it...but how is it doing the RB installer? is iLoader installed first, then launching the RB installer? or both done at once?
09:43 * S_a_i_n_t is curious as to its method.
09:44 < S_a_i_n_t> Nice work, btw...very nice.
09:44 < TheSeven> the iloader installer will just also copy the rb files
09:44 < S_a_i_n_t> This, coupled with the recent "make it really easy to un-fuck a borked Nano" makes installation *very* painless.
09:44 < S_a_i_n_t> good job.
09:45 < TheSeven> no need for ipodpatcher or rbutil any more, just copy a file to the notes folder :)
09:45 < S_a_i_n_t> Could a similar thing be done for RB?
09:45 < TheSeven> if someone writes an on-device installer for the rockbox bootloader, yes
09:46 * S_a_i_n_t looks around for "someone" ;p
09:46 *** timccc has joined #freemyipod
09:46 < TheSeven> what i've done yesterday is just writing a stub that you prepend to an executable, copy it to the notes folder, and it will run it
09:46 < TheSeven> this can work with basically anything
09:46 < TheSeven> you could even boot e.g. disk mode that way :)
09:46 < TheSeven> not that it would make any sense though
09:46 < S_a_i_n_t> nice.
09:47 < S_a_i_n_t> I'm guessing we'll notably see installation/update related fuckups drop off now.
09:47 < TheSeven> i've basically maxed out what's possible with a note... there are a whopping 21 bytes of free space in it, and it's already compressed :)
09:48 < S_a_i_n_t> we *really* need to get people out of the habbit of re-booting RB with menu+select
09:48 < S_a_i_n_t> I realise you've made all attempts to make that as safe as you can now, but, it's simply no good.
09:49 < S_a_i_n_t> I just wonder what makes people think it's correct to do so.
09:49 < S_a_i_n_t> ...and if I can do anything to change that assumption.

15:49 < user890104> yep
15:49 < TheSeven> http://theseven.freemyipod.org/download/installer-nano2g.7z
15:50 < TheSeven> extract that to the notes folder
15:50 < TheSeven> that will install iloader and rockbox
15:50 < user890104> do i need to restore with itunes first?
15:50 < user890104> the ipod's ftl is currently wiped, then the data partition is formatted
15:51 < TheSeven> restoring using itunes might be helpful, yes
15:51 < user890104> i doubt if there are any remains of OF on the FW partition
15:52 < user890104> ok, so time to switch to Mac as i don't have iTunes on windows (and don't have any plans of installing)
15:52 < TheSeven> if you want to test the usual installation use case, restore using itunes, set the language if the ipod asks you to, and then connect via usb again, remove the instructions note and drop mine in instead
15:52 < TheSeven> urgh
15:52 < TheSeven> it won't work with macpods
15:52 < user890104> damn .. so ...
15:52 < TheSeven> you need a fat32 data partition
15:52 < TheSeven> and mbr-based partition table
15:53 < user890104> i remeber that itunes asks if i want to format it for mac or for pc
15:53 < user890104> the fist time i connect it
15:53 < TheSeven> if that works, fine :)
15:55 < user890104> http://www.rockbox.org/wiki/IpodConversionToFAT32
15:55 < user890104> i'm gonna try "the easy way"

15:58 < Farthen> TheSeven, S_a_i_n_t: can anyone of you explain this? menu+select - start rockbox??? http://download.rockbox.org/daily/manual/rockbox-ipodnano2g/rockbox-buildch3.html#x5-280003.1.2
16:00 < Farthen> well, could mean that you can boot rockbox from the osos with menu+select
16:00 < Farthen> well, but we definitely need to make the people stop using menu+select
16:00 * Farthen considers a warning message the first time you press the rockbox button in iloader
16:02 < TheSeven> "In the unlikely event of a software failure, hardware poweroff or reset can be performed by holding down Menu and Select simultaneously until the player shuts off or reboots."
16:02 < TheSeven> this should be pretty much clear, isn't it?
16:03 *** user890104 has joined #freemyipod
16:03 < user890104> TheSeven: it has actually been reformatted as a single-partition 4gb drive
16:03 < TheSeven> and it's also missing the possibility to boot the of by holding menu
16:03 < user890104> after the ftl wipe and restoring
16:03 < TheSeven> interesting
16:03 < TheSeven> no firmware partition?
16:03 < user890104> and itunes does not recgnise it as an ipod
16:03 < user890104> yes
16:04 < user890104> but it's mounted as a flash drive
16:04 < TheSeven> even in disk mode?
16:04 < user890104> it's in disk mode now, and itunes does not list it
16:05 < user890104> disk utility says it's a single partition, and the device is named 4.06 GB Apple iPod Media
16:06 * TheSeven will go home now
16:06 < TheSeven> i'll be back in ~1h
16:06 < user890104> ok, i'll try to restore it in some way

17:14 < user890104> is the iloader uninstaller compatible with macpods?
17:14 < TheSeven> nope
17:15 < TheSeven> at least if they use GPT partition tables
17:15 < TheSeven> it needs an MBR partition table to find the firmware partition
17:18 < user890104> so how to uninstall the remains of iloader? restore the nor backup?
17:18 < TheSeven> either that, or format it as a winpod
17:44 < user890104> i'm trying another method - i've dumped the firmware partition that itunes restored, then repartitioned the ipod as mbr(leaving space for the firmware partition), and now i'm putting the firmware patition back
17:45 < user890104> what type is the firmware partition on mbr?

18:29 < TheSeven> user890104: what freezes?
18:30 < TheSeven> you boot the apple firmware, copy the note, unplug it, it locks up and nothing happens? not even a beep?
18:30 < user890104> after ejecting, the ipod displays its main menu and freezes
18:31 < user890104> actually, 2 beeps
18:31 < TheSeven> a quick low-high beep? nothing after that?
18:31 < user890104> a lower, then a higher tone
18:31 < user890104> yep
18:31 < TheSeven> did you give it at least 10 seconds of time from that point on?
18:31 < TheSeven> it needs to fetch the rest of the file from the flash (takes ~6 seconds on mine), then it will beep again and boot it
18:32 < user890104> i left it for about a minute
18:32 < TheSeven> you have a 2GB flash, right?
18:32 < user890104> still no second beep 
18:33 < user890104> i think it's 4 gb
18:33 < TheSeven> hm
18:33 < TheSeven> how many banks does it have?
18:33 < user890104> how do i check that
18:37 < TheSeven> hm, let me try something
18:37 < TheSeven> damn, space is tight in that note :/
18:40 < user890104> no space for debugging code?
18:40 < TheSeven> i updated the note file
18:40 < TheSeven> can you try the new one
18:40 < TheSeven> there are now a whopping three bytes of free space in the note

19:19 < TheSeven> this usually points to trouble reading/parsing the firmware partition
19:19 < TheSeven> was there anything special about that, or was it restored by itunes or windows?

19:22 < TheSeven> if yes, what did you choose?
19:23 < user890104> i choose no

19:33 < TheSeven> it also failed on mine
19:34 < user890104> so it seems i restored it correctly
19:34 < TheSeven> do you know the svn revision of the last known-working installer?
19:37 < TheSeven> user890104: did it work with r250?
19:37 < user890104> let me see what's my working copy's rev
19:38 < TheSeven> hm, it wasn't changed since like r150...
19:41 < TheSeven> so it must have been affected by something else
19:41 < user890104> i don't remeber what was the first version i used to install on this ipod
19:42 < TheSeven> do you know any known-good one?
19:42 < user890104> i mean that the updates didn't have to re-create appleos.bin because i left it there
19:44 < user890104> my WC is at 246, so is the last installer that i tried
19:44 * TheSeven wonders what could have affected it
20:35 < user890104> i'll try to compile previous versions of the installer
20:35 < user890104> to see which one creates the appleos.bin
20:55 * TheSeven facepalms
20:55 < TheSeven> user890104: forget about it
20:55 < TheSeven> it's trivial
20:55 < user890104> what is it
20:57 < TheSeven> it searches for the "osbk" copy of "osos" that ipodpatcher moved away, which it can't find for obvious reasons
20:59 < user890104> so this method does not touch the firmware partition at all?
21:00 < TheSeven> yes
21:00 < TheSeven> fully transparent to itunes if you don't remove it
21:00 < user890104> exactly
21:01 * TheSeven just uploaded a fixed version
21:01 < user890104> btw, how is the nor reconstructed on uninstall? and what is changed actually?
21:02 < TheSeven> the nor is reconstructed based on the "aupd" image in the firmware partition
21:02 < TheSeven> and partly based on the nor's contents (sysconfig)
21:02 < user890104> some information in diag mode is full of junk chars (which i think is being read from where syscfg used to be)
21:03 < user890104> namely serial number, hardware id and  some other version data

21:36 < user890104> what is the point of containing them in aupd, if itunes does not modify the nor?
21:37 < user890104> and the other data that you are restoring from aupd
21:37 * TheSeven doesn't get the question
21:38 < user890104> i mean why apple put stuff which itunes does not use during the restore
21:38 < user890104> in the aupd image
21:39 < user890104> if it uses them, it should be able to restore the nor when using "Restore"
21:43 *** benedikt93 has quit IRC (Quit: Bye ;))
21:44 < TheSeven> itunes isn't accessing the nor
21:44 < TheSeven> it's all done by the aupd updater
21:44 < TheSeven> and this one apparently does *not* contain those images
21:44 < TheSeven> that's why they're missing in your new dump
21:47 < user890104> so the aupd updater is capable of restoring the norboot.8701 for example, but it doesn't restore it?
21:47 *** Jiss has joined #freemyipod
21:47 < user890104> and iloader remains on the nor even after a restore
21:48 < user890104> i don't get apple's point - why they aren't restoring it
21:48 < TheSeven> they can't
21:48 < TheSeven> the nor reflashing is initiated from, guess what, the bootloader in the nor!
21:49 < TheSeven> if there's iloader instead of the apple bootloader, nobody will care about the aupd file on the firmware being flagged to be executed on the next boot
21:50 < Farthen> design fail IMHO
21:50 < user890104> oh....
21:50 < user890104> it was that simple
21:50 < Farthen> if they made the bootrom reflash the nor it would look different
21:51 < TheSeven> either that (but i undestand why they don't want to access the nand in the bootrom), or have the main firmware do it
21:54 < fmibot> New commit by 3theseven (r256): iPod Nano 2G installer: Use osos instead of osbk and don't tell the user to remove the installer using ipodpatcher on failures if the it was launched through a bootnote.
21:55 < fmibot> r256 build result: All green!
22:04 < user890104> so if the uninstaller just flags aupd to be executed and then extracts norboot from aupd to the ram and executes it... it should do whatever it is supposed to do ... or there's something else preventing it
22:06 < TheSeven> the flag is set by itunes
22:07 < TheSeven> the uninstaller loads the aupd into ram and parses the images out, and flashes those itself, then resets. norboot will boot, see the flag, run aupd again, and it will flash again
22:07 < TheSeven> if i would execute aupd directly, it would get confused by my nor flash layout, because it expects to be doing an update, not a restore
22:11 < user890104> what about the unknown images, are they present in aupd? or they are wiped when first instaling iloader to the nor, and then they are not restored anymore?
22:11 < TheSeven> honestly i don't know
22:12 < TheSeven> i would guess they're gone
22:12 < TheSeven> your flash dump also points to that
22:13 < user890104> i'd like to make another test, but the last time i used writebootflash, it just hangs and doesn't update the nor
22:14 < user890104> i want to see if aupd erases them or just skips them by flashing my initial nor backup, then restoring with itunes
