i am new on this i wos worked whit 6.5 hd2 all things
can somebody give links about why we must check md 5 what is that
some basic things i look on net but is so dificult to understanding

Md5 is like a validation that a package is complete I.e not corrupt. If there is an Md5 value with a download, you run the package through an Md5 app and if the output matches, its all good.
If you're on windows, Google winMd5

Md5 is something like file integrity check.
More info: http://en.wikipedia.org/wiki/MD5
I use this tool: http://www.pc-tools.net/win32/md5sums/
Drag & drop the file on the .exe and it generates the MD5 sum.
5 md I realized how much like a fingerprint jedinstver which every rom there correct me if I am wrong I am specially interested in what was to check the MD 5 the numbers are small, or something within the file, I have not found anywhere video tutorial because it would mean a lot of people who are struggling with English so well as I do, and thus reduce the number of posts with the same issues apologize ...one more for this

We seem to be coming across a number of virii at the moment with people replacing valid tools with trojans. One solution is to provide an MD5 checksum on files you upload so users can verify they are legitimate days/weeks/months down the line. The process is very simple.
1) Zip/rar up your archive as normal.
2) Load the MD5 GUI tool, click the 'Generate Checksum' radio box, and drag your file onto it.
3) Click 'To Clipboard' and paste the result into your forum post.
Users need to perform a similar task, dragging the file they downloaded into MD5 GUI and verifying the checksums are the same.
Background: An MD5 checksum, or one-way hash, is a unique identifier for a stream of data. If even a single character is changed in the stream a completely different checksum is generated. This means if checksums do match, the downloaded file must match the original provided by the uploader.
This information may be old news for experienced users but those new to android may find it useful.
When downloading a new ROM that you would like to flash, it is always possible for corruption to occur. Either in the download itself or in storing it to the SD card. In order to address this issue, most ROMs put out by developers also include an MD5SUM for that ROM. This MD5SUM is used to verify that all of the bits in the file came across right.
Below are instructions on how to verify if the file that you have on your SD card on the phone is not corrupted.. These instructions assume that the file is located at the root of the SD card (as would be needed for flashing ROMs but not necessarily for Recovery Images).
All lines will automatically start with the $ symbol, you need not type this in. Every line ends by pressing the enter key, do not include the quotation marks. The command to show a directory is ls (lower case L and lower case S). this is done in the example to make sure that you use the correct file name when calling the md5sum command.
Open Terminal Emulator
Type "cd /sdcard" and press Enter
Type "ls" or "ls *.zip" to only show zip files and press Enter
This will provide a list of files at the root of the sd card.
Type "md5sum <filename>" substituting the name of the file listed in the ls command for <filename>.
An MD5SUM value will be calculated and displayed. Verify this value against what is published by the developer. If it is correct, go ahead and flash, if not try redownloading the file and repeat. If you continue to get a different MD5SUM value, try downloading it from a different (perhaps mirrored) site
In my example below, I combined the ls command to show only zip files (so that you can see it all on one screen)

Alternatively, you can call the md5sum command with the *.zip or *.img argument and get an md5sum for all files of those types.

awesome!
Thank you for helping new people like me who are just entering the Android game.

Wow, thank you for that! I've been wondering wtf an md5sum is. Now I know.
missing info
Thanks for posting this information - very well written and appears to leave no steps out.
One thing I have to say about a lot of the instructions that are posted about modding - they leave out important step(s) that would be needed to complete the process. Usually it's something that's easily overlooked; what the screen should look like after completing a step, prior to starting the next step. One example, that messed me up (in the past), is partitioning: many instructions gave examples on partitioning, but don't say how to configure the partition (primary, extended, etc)... I had to figure out why my android G1 wasn't working exactly as advertised, because the instructions I found were incomplete.
I think that's why video instructions are awesome - although through bad editing they can suck too.
It's hard work writing instructions, and I thank the people who do, but please write down everything.
This post is just a tangent brought on by reading the original, very well written post.
How did I miss your great post!!! Nice little write up for me checking files on the go.

And for the mac users out there you simply need to open a terminal and type:
md5 <filename>
Or you can get afv (android file verifyer) from the market and just click on the file to generate the md5. Easier if you do it all the time
ahh thanks for spilling the beans
i keep getting "error checking md5sums" when restoring a nandroid back up
I think my SD card is buggered. Its nearly 18 months old and a hell of a lot of transfers on and off it. Maybe time to replace.
i use mand5 and it has an option to google search that checksum. Makes it convenient when devs post the checksum in the OP of their thread because then the search will find it and i can clearly see it's right, 4ext recovery also calculates md5s as well
Another excellent program for verifying checksums on Windows based PCs is Hashcheck. After installation, you'll find a new tab in the properties window of any file which will generate many different types of checksums and contains a box you can type or paste an existing checksum such as one posted with the download. It integrates cleanly with most versions of Windows. You can even use it to create a .md5 checksum file that can be opened to verify the file at any time. This is one of the first applications I install on a clean Windows installation.
And whoever suggested teracopy, it seems to run quite buggy on certain PC setups with mid-transfer freezes and such even on.a fresh Windows installation. SuperCopier is another alternative free file copy/transfer application that I've never seen fail on any of the systems I've used and which has quite similar.functionality to teracopy. Granted, I've only tried a limited number of PCs, but that number continues to grow as I'm basically the technical go-to guy in my family and neighborhood due to my background as a current software programming major.

what should i do to get s-off? i have minu rom 11.19
Redownload the iso or what ever file you need. Make sure you deleat the old file and clear cash just to be sure, also do check md5 again
Sent from my HTC Desire using XDA App
Exactly that, that shows the download you've done is corrupt
This is not a case of S-OFF only supporting anything.
This is to do with the intergity of the file you have downloaded.
If your downloaded file does not EXACTLY match the MD5 checksum on the website - DO NOT, I repeat DO NOT try and flash it, you will more than likely brick your phone.
Burn the CD at the lowest speed possible to avoid errors. Might be a bad CD, not a bad download.
The MD5 checksum is on the download not the actual CD - if the download doesn't match then don't burn the CD
I'm a noob when it comes to Linux and it's commands and I'm currently dual booting with ubuntu (windows installer) and when it says check md5 sums to see if they match i have no idea, how am i suppose to find the md5 sum for my phone because i have no idea. Detailed instructions is greatly appreciated. My phone is currently rooted running oxygen RC 7 s-off stock table.
Thanks,
Ryan
Why would you want to find the md5 of the phone? Since your S-off and running oxygen I'm gone guess you want to change hboot, just download the hboot image, then open a terminal and type "md5sum "with the space, and drag and drop your hboot image in to the terminal window. It might add " to the location of the hboot image so remove those.

You need to check the md5 of the file you've downloaded to make sure it matches the original file on the website. Google it and you'll find some freeware programs that will do the job
md5 is nothing to do with your phone
Let me google that for you.
yeah GOOGLE is your friend
Command name is 'md5sum'. This utility usually comes built-in with linux (most distros should have this..). Go to a terminal and type in:
'md5sum <filename>'
Replace <filename> with the file you want to check and make sure you are in the directory which holds that file.
EDIT: I'm not sure what you meant when you said "find the MD5 sum of my phone"...this is the only way I know of for checking MD5 sums.
In very simple terms:
MD5 provides a checksum for an arbitary file. It's just a string of characters like a long PIN code.
You can use it to guarantee that the file that's been downloaded is identical to the original, i.e. not corrupted on the way. So for any file that has an associated MD5 sum. You download the file and run a MD5 utility on that file on your system and check the MD5 value output against the original one.
There are many other checksum utilities available but MD5 is the one most used currently.
Sorry for beginner-level question...
Via the wiki page below:
http://forum.xda-developers.com
/wiki/HTC_Vision#Rooting_the_Vision_.28G2.2FDZ.29_and_DHD
I have downloaded the file vision.hboot-0.84.2000.zip but the result of the md5sum is not what is shown on the wiki page: 2CE1BDD5E4C1119CCFCECB938710D742...
Could anyone tell me where is the problem?
Is the server of the zip file still trust-able?
I use my browser plugin to check md5sum and it works fine with other files I downloaded...
Thank you for your help in advance!
Possible the download was corrupted. Re-download and check it again.
I just took a quick look.
I downloaded it twice and checked md5 sum twice.
D8F61830F104FF5D48B855BBE0D95F56 *vision.hboot-0.84.2000.zip
File size: 221,206 bytes.
Edit: Here are the md5 checksum for the HBoot download from the cyanogen wiki and xda wiki
D8F61830F104FF5D48B855BBE0D95F56 *vision.hboot-0.84.2000(1).zip
D8F61830F104FF5D48B855BBE0D95F56 *vision.hboot-0.84.2000(2).zip
Edit 2: This is generated with Fast Sum 1.7 from Kirill Zinov, and my HDD has fiile compression on so my md5 maybe different that yours but nevertheless, the files seem to be trust-able.
My guess: The xda wiki folks and the cyanogen folks forgot to check the check sum, or maybe it's just crappy software generate crappy md5 SUM
My advise:
1/ go ahead and use it, or
2/ use cynogenmod guide. I personally used this guide. They're the same anyways.
Cyanogen root guide for the Desize Z
http://wiki.cyanogenmod.com/wiki/HT...26_the_Engineering_HBoot_for_the_HTC_Desire_Z
for the xda wiki, its the md5sum for the .img inside the zip. not the zip.
The cm wiki has the zip of the zipfile, as gu1dry doesn't want to add the extra instruction.

Thank you. I have got D8F61830F104FF5D48B855BBE0D95F56 too!
Oh, I see... Thank you for the info!
