thanks to everybody, i will learn more before do thinks like the mmc boot
is just that i fear the WSOD, it have repair?

Your chances of getting a WSOD are the same whether you try the MMC boot trick or stay booting from internal flash... anytime you reboot your 770, if it's from the affected "middle" batch you have a 50/50 chance of getting a WSOD.

Original 770s and later 770s don't seem to suffer from the WSOD which seems to be a problem Nokia introduced during the mid part of the production cycle and fixed after a few months. Or at least, that's the way it seems. Can't really tell for sure, as there's no way to tell an early model from an mid or late model. Unless it gets a WSOD of death of course...

so there isnt way to avoid the WSOD?
and what are the causes of a wsod?, how can i know if mi 770 is a mid part?

sorry my english, and please, write with more simple english

Correct, there is no way to avoid it. The problem seems to affect certain batches of 770, rather than all of them.

From experience on this forum, 770s from the initial launch period (Nov 2005) do NOT seem to suffer from the WSOD.

Then, at some point early in 2006, the WSOD problem began to appear and once Nokia finally understood the problem they fixed it on the production line - this means that 770s manufactured late in 2006 (after the fix) do NOT have the problem.

Of course this is all guesswork based on information in this forum - maybe ALL 770s are identical. Nobody outside of Nokia knows for sure.

Unfortunately it seems that the "cheap" 770s may have come from this middle batch, or at least _some_ of the cheap 770s came from this "middle batch". I really hope they don't all have the potential for WSOD otherwise this cheap 770 bonanza is going to turn into a very unhappy experience for a lot of users.

See this post:

Basically, when you turn on the device there is a chance that a chip in the LCD panel will be burned out by too high current which is due to a design flaw in the device.

I don't know of a way tell them apart. It's been assumed (at least on my part) there are different production runs (early, mid, late) but it's equally possible all devices are identical with no differences, all with potential to WSOD and it depends how lucky/unlucky you are.

what is a powercicle?

thanks a lot for all the info

The term powercycle is used to describe what happens when you switch off and then switch on your device.

so its better dont turn off, and just close the lid when i dont want to use it (like a sleep mode) and never turn off (and beware with the battery charge)

Yes, that's the point Igor is making - try not to power down your 770 and you reduce the chance of falling victim to a WSOD which only happens when you power on the device (and only if you're unlucky).

ok thanks a lot for the info, now i have a question about uktube, i need to copy and paste the link of the navegator to the uktube and click in show original aspect, then it download a flv, i must to reproduce it with UKMP dark?, but doesnt start, there isnt some easiest way?

ok, i forget to install the mplayer, now work, but in the middle of the reproduction it stop and get bloked, i need to have instaled the ukmpdark?, is this the best way to see youtube?

other question, fat 16 or fat 32?, install apps will slowdown the 770?

another question, can i make the boot from mmc with a 512m card?, what should be the values in

# apt-get install e2fsprogs
# umount /media/mmc1
# umount /media/mmc2 (for N800 only!)
# sfdisk /dev/mmcblk0
/dev/mmcblk0p1:1,15000,6
/dev/mmcblk0p2:15001,,
/dev/mmcblk0p3:
/dev/mmcblk0p4:
