[Verizon] What does this mean?

MD5 Checksum.

I keep seeing this everywhere, but what does it mean to me before I unlock/root my device? Do I have to change something somewhere? This is the only thing that's hanging me up from rooting because I don't have a clue what this means.

To make sure your download is secure. Use a free app (many of them) dnld to your PC and use to compare MD5's listed in dev's dnld's

Taken from the web:


MD5 is an algorithm that is used to verify data integrity through the creation of a 128-bit message digest from data input (which may be a message of any length) that is claimed to be as unique to that specific data as a fingerprint is to the specific individual. MD5, which was developed by Professor Ronald L. Rivest of MIT, is intended for use with digital signature applications, which require that large files must be compressed by a secure method before being encrypted with a secret key, under a public key cryptosystem. MD5 is currently a standard, Internet Engineering Task Force (IETF) Request for Comments (RFC) 1321. According to the standard, it is "computationally infeasible" that any two messages that have been input to the MD5 algorithm could have as the output the same message digest, or that a false message could be created through apprehension of the message digest. MD5 is the third message digest algorithm created by Rivest. All three (the others are MD2 and MD4) have similar structures, but MD2 was optimized for 8-bit machines, in comparison with the two later formulas, which are optimized for 32-bit machines. The MD5 algorithm is an extension of MD4, which the critical review found to be fast, but possibly not absolutely secure. In comparison, MD5 is not quite as fast as the MD4 algorithm, but offers much more assurance of data security.
 
Thank you so much for the responses! I thought it was something that needed to be altered. Good to know!

I don't know, I always thought he was a bit of an a**hole.

His code probably sucks, too. I bet it's stealing bank account numbers and passwords.

:D

With how much he has helped out here by setting up stickys and helping people root I am gonna say I think you are wrong. I've even seen him come into a thread and fix all the wrong info I have given out...:o
by accident of course

I know, I'm just giving him a hard time ;)

For checking on your phone root explorer has it available but I personally like using AFV (Android File Verifier) It is free and from what I hear the dev is a really nice guy

LOL / LMAO, and thanks guys!

(I love you, too! :))
 
Shoot he saw :p

And yes it has been by accident, I accidently didn't make the connection that the bootloader and recovery are not part of the same img ...:o
We should see get a copy of that recovery-from-boot.p file (or whatever it is named) and link to it in the stickys that way if someone is on the stock rom and wants to get back to the stock recovery but they deleted the file they can just download it

Yeah, both good ideas (of course!).

I don't think I ever saw the recovery-from-boot.p file on my VZW phone? (only on the GSM versions?)

I could also extract, attach / post the recovery.img files for each version of the phone and include it in the how to restore the stock recovery (I'll do that :)).

Also, to AppsRUs, you can also easily calculate the MD5 sum on your phone via my app or by Astro File Manager (navigate to the file, long-press filename, choose Details (larger files will take a few seconds to calculate the MD5 sum)).

Also, here's a thread with more/other information about how to check MD5 checksums on both your phone and PC:

Cheers!
 
I had it on mine when I first rooted. I can restore the backup and rename the file back and copy it.

I am begining to think you just enjoy writing how-to posts :p
