How do I calculate the md5 sum before I go flashing something so I can check
Sent from my tbolt running das bamf 3.0
It depends on how you want to check it.
The pinned root guide in the dev section includes instructions for using busybox to check md5s prior to flashing.
md5sum is included in most *nix platforms but most Win users use 3rd party apps.
md5summer, md5deep, etc

I always check them on the device through terminal. You need busybox to do it and know where it is. It's usually in /system/xbin/. That would make your command as follows:
/system/xbin/busybox md5sum /sdcard/pg05img.zip
That is assuming the sdcard is where your file is, and pg05img.zip is the file name to be checked.
Appreciate the help guys I have an application that I use on my PC but I'm on the road right now

I just got an app from the market. Works fine.
What's that app called? I refuse to flash radios without verifying md5

There's no need for an app to do it. Like loonatik and I said, the function is included in busybox.
Open terminal and type what loonatik said above:
"busybox md5sum /sdcard/PG05IMG.zip"
or "/system/xbin/busybox md5sum /sdcard/PG05IMG.zip" if for some reason the other has a problem.
But if you need an app there are a few such as https://market.android.com/details?id=burrows.apps.crypto or https://market.android.com/details?id=com.hobbyone.HashDroid&feature=related_apps
I use AFV (ANDROID FILE VERIFIER) from the market...and its free

Same here. You can even copy and paste the known md5 into the settings for automatic comparison of the next file calculated. Makes it super easy.

If you download the rom directly onto the device you can us a file manager like es file explorer to check the md5 with the one that is listed on the site you download it from.

I use MD5 Checker from the Play Store.
I copy and paste the MD5 from wherever I download it and then find browse to the file and select it. Then calculate to see whether or not it matches. If it matches, both MD5's turn green. If they don't match, they turn red.

MD5 verification is a guarantee that nothing happened from the moment you downloaded the file from a site to the point you saved it on your device or where it is need to start flashing/installation. It is a "legal protection" in case a corrupted file finds its way on installation and causes problems. It is a safety check.
I found all this out AFTER flashing without even checking MD5 on a Samsung S5.
Nothing happened as in most cases but if it did anyone would tell I had been warned.
Agree with @disconnecktie on the File Manager option for any medium users.

do you download the .zip or the .zip.md5sum.txt?
Thanks for the help.
Grab the .zip . The md5sum.txt contains the MD5 hash...which is one method to verify that you've downloaded the full file.
http://en.wikipedia.org/wiki/MD5
Then, you flash the .zip
You want just the zip. The md5sum is just a verification for you to see if what you downloaded is what you think you downloaded.
You can run md5sum on the zip and compare your results to the md5sum file from the repo.

Forgive me, but unfortunately my native language is not English ... So .. my research on this forum are very complicated.
After several attempts and with great difficulty I managed to download from droidbasemment "cm-10-20121030-EXPERIMENTAL-p4.zip."
At the same address I see that there is a file "cm-10-20121030-EXPERIMENTAL-p4.zip.md5sum" which I think is the MD5 of the ROM file of 152.52 MB.
If so, how can I verify the MD5 to make sure that the downloaded file is not corrupt?
Many thanks to those who want to answer. Hi

most recoveries will verify the file automatically if that md5sum file is in the same place as the ROM when you flash it. If you want to make sure now, just open the md5sum file in any text editor to see the correct md5 and then look at the properties of the ROM zip file and look at the calculated sum there and confirm they match.
kRel there is a app just for this, I have it on my pc, give me some time and I will post it for ya. dill

Thank you for your quick response ...
The problem is that ... if I open the zip file "cm-10-20121030-EXPERIMENTAL-p4.zip.md5sum", inside there is nothing!

Thank you ... this applet I also have in my computer. It integrates in "explorer" and is called "HashTab v3.0.0"
But the problem is that inside the file: cm-10-20121030-EXPERIMENTAL-p4.zip.md5sum nothing!
If you have the Wifi 7510 tab that is the wrong md5, you want the p4wifi md5

Do you have winzip or 7zip, you need a file extractor to open the md5 zip?

also...
search market for md5 and you'll find a ton of apps the will calc the md5 from a file you can compare that to the hash inside the md5 file posted by pershoot.
md5sum -c /path/to/file.md5
The *.md5 file and the file it corresponds to must be in the same directory together. This works from your device in a terminal as well.
I discovered the mystery ....
Opening the file from linux (ubuntu) shows a normal text file containing the MD5!
CWM is also able to read and verify the MD5. But I have not understand how to.
Maybe you need to copy the file to your tablet also MD5??

Hey fellow HTC ONE owners,
I am having a bit of an issue. I recently rooted and installed TWRP. (I am coming from the Sensation, so have some knowledge of root & HTC)
I am currently on TMO so I need a ROM using a 4.1.2 base (Either Trickdroid 5.6 or ARHD 9.4) so I can still use WiFi calling. Here is my issue:
Arghhh !!! Everytime I try to flash (in twrp 2.6) ARHD 9.4 or Trickdroid 5.6 , I get the same error !!!

RESOLVED MD5 issue
Yo need to create manually the .md5 file.
1. In ubuntu open a terminal and type
2. md5sum your_ROM_file_whatever_it_is.zip
3. copie that sum that looks like --> 3c70a5afed69871f15c75270ce7dacae
4. create a file named --> your_ROM_file_whatever_it_is.zip.md5
5. open in a text editor and paste the sum --> 3c70a5afed69871f15c75270ce7dacae
6. save it and copie that file in the directory your ROM zip file is

I'm wondering if anyone has a different upload site for the no wipe ME7 factory image. I'm trying to return my phone to stock from root and every zip I have downloaded from android host has an error when unzipping the md5. I would really appreciate this if anyone has one available. I tried it from the OP of the original thread, but like I said the host site or file is being difficult for me.
Edit: Found some mirrors, and everything downloads fine, problem is everytime I extract the file it says its broken and it won't unzip.
You dont need to unzip the md5, just use the md5 in odin.

I know, but the md5 comes in a zip file and I can't get the zip open to get the md5 out lol unless I'm able to flash the whole zip, but last I looked I couldn't, it wouldn't even show the zip to select.

Are you using 7zip?
Sent from my SCH-I545 using xda app-developers app
I tried it with both 7zip and windows explorer
Edit: I ended up getting a new s4 today which had MDK on it which led me to downloading the md5 for the MDK version and I realized what had been missing was the .md5 on the initial zip of the folder which was why it wouldn't flash in odin nor would it unzip. Thanks for the help, I was having a blond moment lol
