There are many N800 and N810 tablets with so called ‘Power on drama’. It appear as device which does not want to power on after shutting down or takes lot of time to switch on.
Few days ago new version of OS2008 was released to solve that. There was no informations about it on Maemo website. I do not know why…
But as usual all they did was release of one big flash image with no instructions other then “reflash your tablet and keep hope that it will restore all your changes from backup”. I decided to not check does “Backup & Restore” application will magically install xvinfo, gvim, powertop, custom kernel and few other modifications which I have on my N810.
So how to get fixed device? All you need is flashing bootloader. On Nokia tablets it is split to 3 parts: X-Loader, NOLO secondary bootloader and NOLO cold flasher. First you need to unpack FIASCO image (I am using N810 image in example):
$ flasher --fiasco RX-44_2008SE_2.2007.51-3_PR_COMBINED_MR0_ARM.bin --unpack flasher v0.8.1 (Jan 5 2007) SW version in image: RX-44_2008SE_2.2007.51-3_PR_MR0 Image 'kernel', size 1529984 bytes Version 18.104.22.168-200749osso2 Image 'initfs', size 1954560 bytes Version 0.95-70 Image 'rootfs', size 137625600 bytes Version RX-34+RX-44_2008SE_2.2007.51-3_PR_MR0 Image '2nd', size 8192 bytes Valid for RX-44: 0801, 0802, 0803, 0804, 0805, 0806, 0901, 0902 Version 1.1.11-1 Image 'xloader', size 9216 bytes Valid for RX-44: 0801, 0802, 0803, 0804, 0805, 0806, 0901, 0902 Version 1.1.11-1 Image 'secondary', size 99968 bytes Valid for RX-44: 0801, 0802, 0803, 0804, 0805, 0806, 0901, 0902 Version 1.1.11-1 Unpacking kernel image to file 'zImage'... Unpacking initfs image to file 'initfs.jffs2'... Unpacking rootfs image to file 'rootfs.jffs2'... Unpacking 2nd image to file '2nd.bin-RX-44:0801,0802,0803,0804,0805,0806,0901,0902'... Unpacking xloader image to file 'xloader.bin-RX-44:0801,0802,0803,0804,0805,0806,0901,0902'... Unpacking secondary image to file 'secondary.bin-RX-44:0801,0802,0803,0804,0805,0806,0901,0902'...
Then all needed is flashing N8x0 tablet with one command:
sudo flasher --flash --reboot \ --xloader xloader.bin-RX-44:0801,0802,0803,0804,0805,0806,0901,0902 \ --secondary secondary.bin-RX-44:0801,0802,0803,0804,0805,0806,0901,0902 --2nd 2nd.bin-RX-44:0801,0802,0803,0804,0805,0806,0901,0902
After reboot you will have your tablet with all your data in same places as they were (because rootfs and kernel are not touched) and it will behave properly on OFF/ON cycle.
