I found that article.
That's the normal way to flash the phone.
If you are experienced and confident than go for it.
But you can find better and detail guides here on XDA.
That is not recommended for new user. Please READ, READ, READ before doing anything.

Hi Nadimpalli so right now u r in stock gingerbread naa...
if u r unable to update your note via kies just download N7000DDLP8 INU and flash it via odin in your note it is the best way...

Please see teh first thread in this forum it has links to many relevant articles that you might want to read...
I couldn't get all what you mean but here goes it...
To keep your phone memory empty you can move apps to sd-card...Learn more at http://yagyagaire.blogspot.com/2011/09/how-to-install-applications-to-sd-card.html
If you are looking for Samsung Firmwares latest is 2.3.5 (not Official for all regions). There are many custom roms (not by sasmung) available to install and most of them are based on GB 2.3.4 (so they are also like latest). Please find more info in their threads in Development section of Galaxy Mini forum.
Updating will remove all your apps, settings, data, etc. and install a new firmware. So, it is a most to do a backup of your apps, contacts and other data first. You data on sd-card will be safe.

man
i upgraded my phone using 1 file method
i sucessfully updated it
now theres a problem
im unable to root my phone by superoneclick

Nothing offensive but that's why noobs shouldn't root their phones.
What android version do you have btw?
If it's 2.3.4 you could try yagya's tutorial on his site: yagyagaire.blogspot.com/2011/08/how-to-root-samsung-galaxy-popmini.html
If it's lower, you should consider flashing 2.3.4.

Read second line on my signature. - Root galaxy Note.
I'm sick of this
Samsung recently released the new XXLRQ (ICS 4.0.4) Update for the Galaxy Note GT-N7000 that combines features from Galaxy S III and the Note II, I'm pretty sure you all know about this.
So I flashed the update using ODIN and it worked perfectly, the ROM is great and all but the problem is the Network Lock Key !
I can't use my phone as AN ACTUAL PHONE! No calls, no texts, no mobile network, nothing!
Any help ??
Thank you

just go in settings and then navigate to software and in that there is "check for updates"
one advice: get some basic information regarding rooting,recovery,kernel etc....i root my phone after doing research for month and then i proceed.here in XDA lots of information available very easily just go through posts and forums.read and re-read then proceed.
if u do something wrong we are here to help you but make sure you know what you are doing.

Follow these steps sequentially; safest, tried and tested by over 10,000 people on GT-i9000:
1. Go back to stock: Flashing To Original Rom - Using Odin on GT-i9000
2. Root your device: Rooting GT-I9000 2.3.3 [India DDJV9]
3. Install ICS: Installing Ice-cream Sandwich 4.0.4 On Samsung Galaxy S GT-i9000
4. Install JB: Installing Jelly Bean 4.1 on Galaxy S GT-I9000

Better to root the phone before or after the JB upgrade?

newest JB version is russian: I9070XXLQ4
previous one was: I9070XXLPZ
you can download it from samfirmware.com and flash with odin.
I guess you might have root / custom kernel on your phone and that is main reason for those errors.
Hello guys I just sold my 4S and bought this Note 1 , anyway im new to android flashing and this stuff , ive heard that its way different than iOS restoring which is really easy and simple. Right now i got a few questions , If i missed a step or did something wrong it'll render my device unusable ofcourse , but will it be unrecoverable ? Thats the first thing. Second thing is that is it recommended that i install custom roms? right now i need one's with the Water Ripple effects on lockscreens , or if you can just tell me how to install the effect without custom rom's that'll be helpful because i want to flash official 4.1.2 jelly bean first and then the lockscreen effect. Im just new to the Android stuff and i dont know where to start Same feeling back in 2008 when i bought my first iPhone and got confused n' all
Read around for awhile, its what got me started when I first came here.
Again, read, read read, and avoid asking questions which have been answered countless times its annoying really.

Sent from my GT-N7000 using xda app-developers app
If you just install stock official 4.1.2 rom via odin, it should come with the ripple effect.
Or if the update is already available in your country, you can just update it to the latest official rom via kies.

You'll notice that all of the download links are zip files.
You just need to extract the zip file until you find the .tar file.
Get 7-zip if you don't already have an archive reader.
Help with kernel
So recently I rooted my Samsung Galaxy Note GTN7000 and flash it with franco kernel, then when I turned on my phone the bluetooth is not working and it constantly crashes and get stuck (The screen just go green and pink like an old TV with bad signal). So I panicked and unroot it immidiately. But that didnt seem to solve the problem.
So my question is, can I flash it with the original kernel. If so how? and where can I get it. can you teach me. (NOOB REQUEST )
just flash the stock rom again... using PC odin
Alright guys thanks for the reply , i heard theres a way you cab install roms without pc since i just want to install official 4.1.2 , ill do some research

Yep, there's a way to install roms without PC, using mobile Odin, but before that you should have your phone been rooted first.
Well i can upgrade with PC but im kinda afraid .. All i want is just updating to jelly bean official on my note , I searched for about 2 days and learned how its being done but while searching i came to posts showing people crying cause they got their phone bricked cause of kernel blah blah , i also saw at the end of the installation guides that it will get my phone in a boot loop or stuck at samsung logo and im not sure xD i just want to update and im taking it seriously cause i dont want to brick my phone ..

Wait a few minutes. Let me get on my PC and I'll give you step-by-step instructions.
Now, do this:
Since you're scared, we'll do this the safest way possible
1.)Download a stock GB rom from here.(You can always come back to this ROM if you run into any trouble).Flash it via PC Odin.
2.)Wipe data and cache from recovery (Press Vol Up+Power+Home when phone is off in order to boot to recovery)
3.)Download stock JB rom from here.Flash it via PC Odin.
OR
1.)Update using Kies.
You're done
Alright ill do this when i get home , hehe thanks man ill update this thread if i get into any trouble

Yes, then you'll have gingerbread. Don't forget to wipe after installing gingerbread.
It may brick. Not definite that it will brick. Still, better safe than sorry. Never wipe on stock ICS kernel!
