i have one n900, but when i turn on this phone it displayed text: Missing image. I don't know anything about that. i searched google and has a person told me flash n900, So does anyone can guide me solve this phone ? thanks

Have you tried a search?

There are at least five:

• At the top right, a white box with Search written in it and an orange OK button next to it.
• In the menu on the right, with a down arrow next to it. It opens a popup with a search field and a Go button.
• The same menu also has a Tag Search...
• ...and Advanced Search option.
• Not to mention Power Search, also in the menu on the right.

Failing all that, when you start a new thread, you get a list of offers of threads with similar topics. I tried starting a thread with your title and at least one of those offers was useful.

Did you miss all of that? Spoonfeed.

ooohh...
Pichlo....
careful with the newborn... gramps ...
they are fragile..

But Pichlo is right ...
there are plenty of threads explaining how to help you...
Hell ...when I was new I came bumbling and stumbling through this place...pretty much the same...
and I must admit I have had my harsh moments too ..for the newmo's [copyrighted and trademarked]

But It's ok New Guy...
[If you stick around long enough to become a fixture here.. I'll commit your name to memory..until then you are "New Guy"...]
learn, learn, learn, ask questions, get help...
and in the end you'll be empowered and you'll end up just like Pichlo and I ...yellin at the newmo's .... "durn blasted kids..get off the lawn!"
heheheheeee


just check out how to unbrick like the last link in Pichlo's post.
Hopefully you can bring your device back..
If you need help post in one of the threads pertaining to your prob...
failing that ask by private message for help from a competent member...
By the way...
Competent members don't include me..

Nokia N900 by far most adventurous phone ever, scattered treasure maps, surprise messages in a bottle, yes after finding out about the really powerful power search i barely have to type in a captcha anymore when not logged in and land comes earlier in sight
AHOY

hehe
Dongle got it...
Best devices, best os's, best software, and best home [maemo.org] ...bar none...on the planet.

Oh and New Guy...
I gave you a freebie ...
you need at least 5 [or is it 10?...been so long now..] accumulated "thanks" to be able to pass the mechanical guard dog....
to finally be able to post private messages to fellow maemoans ...
which will be invaluable in helping you...
by asking questions directly of your fellows...

OP could have at least asked the question in a relevant thread instead of starting a new one, but you have to keep in mind that there are a lot of confusing posts, broken links, not working repo's on this site.
The wiki is not always very well maintained and it made me doubt the validity of every post if it was older than a few months and not confirmed by long time members. I have spent a lot of time just trying to figure out what is still relevant and what is not. Where can someone find a current tutorial with a link to the best/latest flash image from a trustworthy source is a perfectly fine question imo.
