MD5 hash checks, flashing radios, kernels. Could someone explain these?

I just got my Thunderbolt last Thurs. I was previously using a Droid X so these things are all new to me.
What is a MD5 hash check? What if they don't match? Will it brick your phone?
What's the advantage of flashing a new radio? I've noticed that some ROMs require you to flash a new radio. Why is this?
I don't plan on flashing a new kernel but from what I understand it's just a way of adjusting the processor?
Thanks in advance.

First off, Google is always your friend...
MD5 hash checking is basically a way to check to make sure a file is identical in different locations. Often, when people post download links, they'll include the MD5 hash of the original files as they uploaded it. You can then verify that your download file is identical to what they uploaded by generating your own MD5. If they values match, then you're good. If they don't match, then the file you have is different. It could be that someone messed with it (a possibility when downloading from mirror sites) or that it was corrupted while downloading.
You should never try and use a file if the MD5 hash is wrong, especially not when it comes to flashing your phone which is why it's included with almost all downloads you see on the site.
The kernel is basically the low-level operating system of the phone. People tweak the kernel to get desired outcomes such as a faster data speeds or improved battery life. Some of the developers are actually quite good at this, for example, I noticed that on my TB, just when idle I was losing battery at a rate of 22%/hr. I then flashed Leankernel and I've been getting a battery loss rate of 9%/hr while I actually use the phone!
As far as the radios go, it's basically the same thing, just the software that drives the radios. There are a few versions floating around out there, the later version is supposed to be tweaked for better performance and less bugs. As for why some ROMs require it... I'll pass that off to someone more knowledgeable.

How do I flash a new radio? Is it the same as flashing a ROM? Just use CW?

NO! It's done through hboot, not through recovery.

To flash a new Radio, you need to download the file (it will be named PG05IMG.zip, and will be about 25MB in size), and place it in the root of your SD Card (not in a folder).
After that, you want to root into your bootloader (power off your phone, hold the volume down key, and turn it on), select the default option, and it should recognize the update within a couple of seconds, and prompt you to install it.
Hope that helps!

Okay, thanks. And I think I've read that I need to remove the file from my SD card afterward so it doesn't revert back, right?

Its a good idea to remove it yeah. It will at least try to do the update again I'm not sure if it will revert back to be honest, I've never tried it.
In any case, best to clean up after words. I have a folder on my SDCard where I put all the radio files, and move them around as I need them.

I know that there is somewhere I can download the zip and just flash it like a ROM, but I don't know where to find the ZIP?

No, don't flash it through recovery. You need to flash it in bootloader mode(hboot).
Put the PD98IMG.zip on your SD card(check md5 on computer)
When its on your SD, open terminal emulater on phone(install from market if you don't have sit-up its free)
Type in terminal-
md5sum /sdcard/PD98IMG.zip
Make sure it matches the md5 from pc.
Power off phone.
Press and hold volume down, then press power.
Now it should start the process automatically.

I understand most of this.. but I don't know what you mean by "(check md5 on computer)"

Google md5 checker, simple tool that will read the file and tell you if it matches the md5 number of the original file. Course you could go to the market and get manD5 which allows you to check the number after its in the root of the SD card.
With a radio I would check it at both times simply because you can't be to careful when it comes to flashing radios. Remember measure twice cut once.

is there no better way to do this? I flashed my last radio by installing the file on my SD and flashing it from hboot... that was it..

Nothing has changed, that is still the same procedure. All that they're telling you to do is check the md5 hash of the file to guarantee that it's not corrupt. You don't want to flash a corrupt .zip file in hboot. But if you feel adventurous you can skip the md5 check. Chances are low that the file will be corrupt if you downloaded it correctly and copied it to your SD card correctly.

As low as chances are, I have an EXTREMELY fast home internet connection that usually doesn't drop nary a packet. However, 2 releases ago when I downloaded the iso for Fuduntu 32 bit (shameless plug) I didn't check the md5 hash before rolling it into a torrent and started seeding. Long story short, our official 32 bit torrent had a corrupt iso image.... check the md5. I use Hashcalc on windows (it has a nice GUI) and MD5 Hash Checker on my phone (it too has a nice GUI, a feature I chose to search for when tab completion refuse to work in my terminal emulator)

Ya just check it.
corrupt radio=permanent brick

Indeed, it does happen.
I downloaded this very radio in question the other day on a solid WiFi connection.
Checked the the MD5....failed. Two totally different numbers. I had never had a download not pass an MD5 check before, so I was almost a little stunned. I re-ran the check just in case I had somehow chosen the wrong file or something. It was indeed bad.
Redownloaded, rechecked, passed. Flashed successfully about an hour ago.
Check your MD5's people. You'll never forgive yourself if something bad happens that was easily avoidable.

[Q] How and when to check md5?

Hi guys. I've flashed several ROM's to my sensation now. All have installed fine with hardly any problems, as I follow the instructions provided. I'm fairly new to android... so what is MD5...how do i check it? and when should i be checking it?
I read that i should use it to check the integrity of a file... but which file, when and how xP
Thanks in advance!

It verifies that the file isn't corrupt. You can use software designed for md5 on the computer or from the phone itself.
You type the md5 numbers and letters into the app, then choose the file to verify it with. I use mand5 on my phone for instance.

There's no need to be a complete douche.... I already googled MD5 , but there's not much explaining how and when to use it... Just says what it is. I think you need to find something better to do with your life than being sat at a computer all day making pointless comments on a forum designed to help people...
Thank you to stonew , big help

It refeers to the integrity of the rom installation file, so u make sure the rom file being installed isn't corrupted.
Only this.

as you know you can brick your mobile if anything goes wrong in flashing things to your mobile,,,,,
so for the best result and to be sure that you have downloaded a good file as the developer want it to be,,,,
you have to check the MD5

[Q] CWM recovery filenames

This is a general CWM question but I could not find any place better to post on XDA, so excuse this if incorrect location.
I have flashed all the Skyrocket ICS roms in the past few days to see which I liked best. Before I flashed a new one, I would make a CWM backup of the current one. Wanting to easily be able to identify the files, I appended the rom name to the end of the CWM filenames after deleting all the characters after the date, which appeared to be a GMT time stamp. Now, when I try to restore any of those files, I get an MD5 checksum error. I am only assuming that this is due to changing the filename and not some other problem. Anyone have any ideas on how to fix this? TIA.

Are you talking about the folder name? Because that shouldnt affect it. Inside the folder that is created for each backup, there are backup files which dont have any dates/times in the filename itself.

I vaguely remember reading about this, but I can't recall how it was resolved. Try updating your can to 5.5.0.4 Touch or 5.8.1.3 (?? something along those lines) and seeing if that resolves it. Outside if that I must ask the obvious, did u Google "md5 checksum error cwm"?

Are you using the same CWM version as you did when you backed up? If you didnt, then thats one reason. You have to stay on the same CWM version, many of these CWM versions floating around have different fixes in there.
One way around this is to go to Advanced Restore and restore all the IMG files from there.

I figured I would post this fix here in case anyone else ran into this problem. This is assuming you did not change the folder names and let Clockworkmod create them. I haven't had it happen until today, but it's not a nice message to see when you are trying to do a restore.
Code:
Checking MD5 sums...
MD5 mismatch!
Do this to fix:
To fix this problem use the code below. Substitute the final folder name for the backup you need to fix.
Code:
adb shell
# cd /sdcard/clockworkmod/backup/2010-06-29.20.22.53
# rm nandroid.md5
# md5sum *img > nandroid.md5
When that finishes, re-run the restore and everything should be fine.
NOTE: As rpearl stated, there could be something really wrong with your nandroid, so use this tutorial as a learning experience and not a fix-all. In my case, everything was fine after restoring. However, that may not always be the case. Do this with caution.

That is correct on most of them. I updated to CWM Touch for the last one, but it did not restore either. To check this out, I just did a backup and without changing the name did a restore and it worked fine. The thing that was odd in the backups that would not restore was that it immediately bombed out of the checksum each time as if it was checking the name itself first.

That is brilliant. I did not realize you could generate the MD5 from ADB and stick it right into the folder. Thanks!

The few times this md5 mis-match has happened to me was because (a) the backup was actually messed up (check folder size) probably due to corruption or (b) my SD card was out of space. I've always renamed my backup set similar to yours (I append the ROM name) and it never affects the restore.

Are you using touch or standard CWM? I wonder if this only happens in touch version. I will try this in the next few days.

I changed the name of one of the backups I created with CWM touch and it restored fine using touch. I suppose my earlier problem may have been trying to restore a backup created with old CWM using touch version.

well since you are on the subject cwm touch im making a nanadroid backup of my current ics rom right now as i speak. i started about an hour ago and its still on the backing up data part. when i used the older version to make backups i dont remember it taking this long. have any of you had cwm touch take well its been a little over an hour now? i do have more apps on my phone now than i did the last time i made a backup would that matter? should i just jerk the battery out and go back to the older version of cwm i was using? thanks ahead of time for any advice / help you may give i would appreciate it. im trying to backup this rom cause i want to flash a different modem cause the ics modem form the leak is crap and need a backup in case it dont work..

If you are using sk8erwitskil version of the CWM touch (ClockworkMod TOUCH 5.5.0.4 v3.5) then most likely you didnt follow one of the directions on the front page. This is a known issue. Here it is again. You need to create that file on the location you backing upto.
For CWM to recognize the .hidenandroidprogress file you need to boot into CWM and go to mounts and storage>>mount /sdcard then go back to backup & restore and make a restore and it should work everytime (as long as you do the steps in that order and you have the .hidenandroidprogress file in /sdcard/clockworkmod & /sdcard/external_sd/clockworkmod folders)
There is a known bug in ClockworkMod 5.5.0.4 that long file names can POSSIBLY cause backups to hang. There is a solution/workaround:
•boot into recovery
•try to make a backup (no matter if it passes or fails proceed to next step)
•either through terminal emulator or through adb run the following command EXACTLY:
Code:
touch /sdcard/clockworkmod/.hidenandroidprogress
•if you are backing up to external sdcard then run the following:
Code:
touch /sdcard/external_sd/clockworkmod/.hidenandroidprogress

im using 5.8.1.3 hercules that i got from the dev section. is this a known issue with it to?

Not sure, I used that for awhile but then went back to the other touch and Ive had those two files still in my directories.
I would go ahead and create those two files (one for internal SD and one for external SD if you got one you are using that is) and try it again. Make sure you call that file exactly the way it is, or copy/paste the code identically if you do it through ADB.

Well the crazy thing is after sitting there over an hour waiting I finally took out the battery and even though it never said complete all the files are there but I still don't trust that it made a good backup so I deleted those files tried putting in the code above and it still would not work so I flashed back to version 5.0.2.0 thats not touch and it made a perfect backup in under 2 minutes. Might be one of those it just ain't gonna work right on this specific phone thing or it could be the little green gremlins at it again lol... who knows.. I'll just wait for new version of touch to come along and try it. It won't be long till a newer greater version comes along as fast as technology is going today.. thanks for the help. I'm learning more and more each day from you guys on xda.....

Not sure if this is the cause of the issue but for nandroid backups you can't make a folder name with spaces otherwise you will get an md5 sum error. Try renaming the folder with underscores instead of spaces

4.3 help!!!

I have an N8013 and I have been trying to go to 4.3 for a while. Like illusion rom... i've tried cwm a few versions even the latest, twrp, and even philz recovery as recommended and I even deleted the updater scripts as recommended. I for the life of me can not get past the zip file failing to flash. I've downloaded the rom multiple times, used odin to go back to completely stock, factory reset.... just about everything. There is one other dude tellin me to do this....
"I have a N8013, and deleting the assert and getprops works for me 100% of the time. However, it is important to note, two things. One you have to have the N8013 version of the ROM, which is labeled N80xx, and 2, when you go to install it after you have modified the file, you will get a validation error because the zip file will no longer match the MD5 validation, you have to install anyways. Other than that it works fine on my N8013, using CWM 6.0.3.1, running official CM 10.2."
But I dont know exactly what file he is talkin about. If ANYONE can help me out with this id be forever grateful.

First thing first. I'm guessing from what you don't understand is the MD5 validation.
So let me try to explain it. Doing an MD5 check, is basically checking the fingerprint of a file to the fingerprint posted. You get an MD5 sum by running it though a MD5 hashing program. Someone that knows the terms better then me will probably jump in and correct my terminology. But the best way of saying it is that by comparing MD5 sums, you are able to see if a file is unaltered.
Second, you'll want to make sure the file you download is compete and uncorrupted. So you run it though the hasher, and get the MD5 sum to check it against the posted numbers.
For "Illusion-v2.5.alpha-UNOFFICIAL-n8013.z" the MD5 Sum is: 95eb24cadc1a7721934a508e3ce97212
For "Illusion-v2.5.alpha-UNOFFICIAL-n8000.zip" the MD5 Sum is: 7789f71ca54647b43c352837702795a3
Now as for a hashing program, if you are on Windows, I would suggest a program called HashTab. http://implbits.com/
It puts the hashing into a tab so you can just right click the file, click Properties, and then "File Hashes"
So for the next thing that you need to do to make sure everything is good, is to check the MD5 sum of the file you download (unmodified) and make sure it is a good download. If all of that is good, then something else is going off.
I will note that right now I'm running the n8000 version on my n8013. Yes there are reasons I do that, even though the GSM hardware isn't in place. But using the n8000 version makes use of VoIP phones much easier.

Wow, thank you sir. No one has ever explained it to me like you did. I honestly appreciate it. I have a PC running windows 7 and I also have an iMac for my music. Not saying I completely understand how to do what your telling me but it puts in to a much greater perspective and for that, thank you. I know something is going wrong. This isn't my first rodeo but I definitely don't know how to change stuff around or dissect it yet. I started rooting and modifying about a year ago. Im a tech so in interests me. But I don't all that much time to dissect yet or understand what your saying exactly. I guess I just need a good download. Maybe I'll try the N8000 version instead. I don't care about the GPS and I use VOIP a lot more than I would GPS. I'll try that I guess. But thank you for the great response and for taking a moment to help a fellow androidian out.

Thought:
Could it be that im downloading the rom to my iMac, transferring to my pc via flash drive thats corrupting it somehow? I dont have hemidal or samsung drivers on my imac but it seems to download the files faster thats why im doing that. But when it finishes its a folder not a .zip so I transfer it to my pc and compress it with 7zip.
I think other people are getting the same error tho as well so maybe not..

Well to start, would be to download the Hashtab program and install it. That gives you easy access to the MD5 sums that you'll need so you can verify downloads.
Now on your Mac, I can only tell you how to do it from the command line. Open up a terminal window and type in without the quotes "md5 filename" replacing filename with the file you want the MD5 sum for.
Hashtab is a nice user friendly version, but it is a 3rd party program. Some people don't like those. So your choice there.
I can also tell you of the only real problem I have had so far with the Illusion Rom. Bluetooth Tethering doesn't work. Now what I mean by this is using Bluetooth on a Cell Phone to give Data to the Note is problematic. DHCP doesn't work til launched manually, and DNS servers don't work. So as long as you don't use Bluetooth Tethering for your Note you'll be fine. But if you use Bluetooth tethering ( a small group of people I know) might not want to upgrade quite yet.

Now this explains the entire problem... Your Mac is unzipping the file, and probably destroying some of the symbolic links. Rezipping it still leaves the broken links and causes problems. I don't remember how to tell OSX (Mac) not to auto unzip files. But you'll need to do that or download it on your PC.

Now this explains the entire problem... Your Mac is unzipping the file, and probably destroying some of the symbolic links. Rezipping it still leaves the broken links and causes problems. I don't remember how to tell OSX (Mac) not to auto unzip files. But you'll need to do that or download it on your PC.

Dont you mean how to tell a mac how to autozip the files? But again thank you. That helps a lot.

From how it sounds your Mac is auto-unzipping. You want the Mac to leave the downloaded zip file & leave it alone. Not to unzip & rezip it up. That is what is causing trouble, the unzipping and rezipping more then likely. So disable the "expand archives". Doing a quick search try reading up on it here to get Safari to behave. https://discussions.apple.com/thread/1483114?start=0&tstart=0

Just needed that key piece of info. That you where rezipping the file after using your Mac to download it.
Hope it installs this time around. But I would suggest learning how to check the MD5 sums as well. Doesn't hurt to be careful.

I completely agree. And I plan to. Didnt know it would be that easy. Again thanks man. But you completely helped me understand. I love learning about this when there is someone willing to teach.

I just downloaded the rom on my pc and its doing what it was before. I try putting the zip file in to my internal sd on my tablet and it says "CAN NOT COPY ITEM, The device has either stopped responding or has been disconnected"
It has not I can assure you. I've tried rebooting the tablet and pc when this happened before and still with no avail. I can copy other files to my tablet no problem. I've never ran into this before.
I cant even open the zip file or extract it to my desktop right now. Seriously, what the hell.
says windows cant open it cause the file is invalid. Must be that MD5 thing your tellin me to do. So now That im doing it on my windows pc should I install that program you mentioned?

I've had that problem before with windows. Not sure exactly what causes it, my guess is some data on the usb connection is causing it. Wrong driver or something.
When it happens changing USB ports, sometimes helps. Or you can use ADB to copy the file over. Not sure if you have used ADB before or not. The third way is to pull the Micro SD card out of your Note, and use an adapter (SD to USB) to put the file directly onto it from windows.
Only options I can think of off the top of my head for that problem. But it is one I've seen before.

Great ideas! I can try the sd one tomorrow. Day 3 lol. Wish Me luck

I may have missed this part, so I apologize. Is there any reason you can't just download it directly from the tablet, saving it to the sd card? It would assuredly cut down on the headache and potential file corruption during transfer between devices.

Already got cm10.3 up and running. The developer gave me a nightly build that had all the files taken out already. Had to download it twice but got it after putting it on my internal memory. Thank you for your help. The note 10.1 has a good community of people.
