Wan-King wrote:Hi Guys,

First of all, many thanks for all your hard work. Thanks to you my ageing 2006 TomTom 910 is now brought to 2011.

I used the SE 9.205.547817 for 32mb devices package,
1. then upgraded the boot loader to 5.5259 without a hitch, now running australia 860.3101 and europe 860.3102 maps.

2. It was a clean install, everything backed up first using the windows explored,
3. then formatted the HD, then updated. I had to copy (overwrite) the old loquendoTTS folder to the root of the device to get the voices back after the update.
4. I also got rid of the Outsorced folder, as per the forum instruction.



I now have a few (minor) issues;

the power on is very sluggish, especially when connected to external power. Pressing the on button does nothing most of the time, but exactly 45 seconds after the power is applied to the car mount, it will power on, but it would be a "reboot" style power on, as if it was removed from the usb bracket after an update, i.e. first the boot up screen, then the tomtom screen, then the splash screen. It then works normally and when the power to the car mount is removed, it goes off in 10 seconds,as expected.

I could not get the mapsettings.cfg to work even with adding the fake favourite with tomotom home, eventually I got it to see the old favourites without rebooting, but as soon as one was selected (navigate to) it would reboot. I am not that bothered about this, happy to redo them again.

Very slow when recalcuting the route if one deviates from the original route. Again, I can live with this too, jus wanted to know if everyone else is experiencing the same.

Apart from the above, it is back to being the top dog again, very many thanks!

PS For what is worth, I had the base connector repaired (the non charging issue, with broken solder pins) but after the repair, it worked without a hitch with the old 7.903 navcore.

I would be gratefull if someone in the know can shed some light on the power issues.

1. About the bootloader, I read the reply 36 to 38 here http://www.navitotal.com/forums/showthread.php?2831-TomTom-Automatic-Navcore-Installation/page4 and thought the 710 would be very similar to 910 in the way it runs once powered up. I used the cab file recommended in post 38 and that took the orignial bootloader 4.88XXX to 5.5259. I suppose there is no way to downgrade back to the original 4.88xx even if the backup running navcore 7.903 with the original bootloader is restored? Doh, I should have spent more time reading the forum!

2. I went for a clean install because I had few problems with bad clusters on the drive in the past and the unit was running slow until I defragmented the drive and marked the bad clusters last year. that improved things and I thought the most recent upgarde would be the perfect opportunity to see if the bad clustes on the HDD were permanent or just corrupted. Full format took care of them. I believe this was caused by the bad battery that was replaced with a new one about the same time. The base connector got broken a few times in the past, I kept fixing it until it came off completely after a long trip in january. I dismantled the unit completely, superglued it to the pcb first and then resoldered all joints back. I haven,t had a problem since and I know it was charging fine prior to the new navcore upgrade.

I am going to try tendrivers insctructions and files in the post above, after I restored the old setup. Will let you know how I got on.

many thanks again!

1. Format HDD
2. It looks like it is not possible to downgrade the bootloader from 5.5259 to 5.5250

Wan-King wrote:Top stuff DU, worked exactly as you said, now my bootloader reads 0.0000 meaning the TT should take the bootloader upgrade to 5.5250although the power issue is still there with it and I'll try the correct 5.5250 this one seems a little more stable and faster when browsing through menus, so I may go back to it after all.

1. TD, I was referring to the second boot screen after a new "system" file is added or overwritten. when the actual bootloader upgrade takes place one gets a brief "please wait" screen in all languages, the critical "have you battery fully charged and do not interupt until finished" moment. If this does not take place on the first bootup at least once after the new "system" file is placed in the root of the device, the bootloader upgrade is not taking place?

You are spot on, bootloader 5.5259 with 9.205.517817.1 (for32mb devices) is fine apart from this power on issue, which, if all fails, I am just going to have to live with.

Many thanks for your guidance and prompt help guys!

I nominate DU's reply #8 for a "sticky" for all the people whi got their bootloader wrong!

You have gone to an awful lot of needless trouble & worry over the bootloader. I only mentioned it as an advisory & am now sorry I did.
