That's why it got writ. Most people dislike raking around in the Java folder and CrackMem will take the pain out of that part of upgrading.

It can easily be beaten by those who have the expertize and know just what they want. But, CrackMem is safe and reliable and it can leave the OS just as you found it.

btw: I just tried it on an 8800 for the first time. It worked just fine.

Looks like a keeper.

I had tried to use this with my upgrade (8310) from 4.2.2.194 to 4.5.0.81... but no go. I chose to remove all of the removable items and did the upgrade. It obviously did remove the vendor.xls file, as the upgrade went through, but all of the items were moved to the new OS install on the 8310.

I was forced to fallback the old method - removing the.cod files from the JAVA folder. Fortunately I had already created a batch file to do so, so tweaking the batch file was simple enough...

I am disappointed in the performance of CrackMem 2.4.

100% behind you on this one.

they are both a business and a business has to have customers . So in a sense they are competing.

You are absolutely correct from a business point of view. In fact the name of the game with websites is, of course, attracting advertizers. The more people you attrache to your site, the more and better advertizers you get which, in turn brings more visitors.

From my standpoint as a user, I just see all these sites a little like libraries. I can read any article from any of them.

I also think that with OS 4.5 and new phone models being released we need to improve communications as much as possible.

hey pete, i wonder if you can add removal languages module and dynamic_ling to the next version

I am puzzled by what happened when you ran CrackMem. It has been downloaded over 250 times across 3 sites including this one ans apart from one user who has his Program Files folder on a different dsk from C: nobody else has reported problems.

CrackMem was developped from a series of batch files that I used to use.

I counsel you to read the Help text and to follow the program flow as laid out there. I am sure that you did every thing right but I would like to know how you got the results you did which are clearly not as you expected or, as I intended.

This program works, no doubt BUT if someone has managed to break it then I wish to fix it.

It is easier to remove languages via Desktop Manager. Remember that I am not trying to replace DM here.

What please is ' dynamic_ling '?

Pete can you please stop making such good programs.

Crackmem alongside the drip of OS updates is costing me sleep time in staying up and getting the things downloaded and installed.

they are of course good things really but sleep would be good

dynamic_ling is suretype pre define dictionary, you can search it on java folder of the suretype os devices

Yes, I can remove this but on a per language basis it only takes up between 40 and 300Kb. It seems to be present for both Pearl and Curve devices.

I do not know what this file set does so before I remove it, I shall find out more.

Thanks for the information though.

I shall look into this when I get back from vacation. I am leaving today for 2 weeks.

Pete, I am puzzled, too... and FWIW, my post was intended as informational and NOT complaining or otherwise intending to offend. I have no idea what I did or what happened. As it stands now, my OS is installed and stable, so I won't be playing with it for a while - at least until the next release

The next time I do an install, I will try CrackMem again and see what happens. People have had success with CrackMem, so I chalk this up to 'operator error', until I can document and prove otherwise.

enjoy the holiday

I realized that you were not a rock thrower. There is a known problem when, as I said, the pfogram files folder is not on C:. This will get fixed in the next release.

CrackMem should really be used before you connect your phone or run DM to do the install. It is really just a replacement for dragging files out of the JAva folder manually and you would do that before you started the install.

It is always difficult to use a program like CrackMem correctly since it is slid into an existing manufacturer's installation procedure.

I really want to get to the bottom of this. as I am sure you do.

Please could you have a look in C:\Program Files\Common Files\Research In Motion\RemovedFiles which is where CrackMem stores the files it removes.

The contents of my RemovedFiles folder is this

8100-v4.5.0.55_P2.7.0.68
8310-v4.2.2.194_P2.5.0.44
8310-v4.5.0.55_P2.7.0.68
8310-v4.5.0.69_P2.7.0.72
8800-v4.2.1.101_P2.3.0.80
Vendor.xml

Which is a list of the OSs installed on my PC. In the 8310-v4.5.0.69_P2.7.0.72 folder I have 63 files (all .cods). These files are the files that CrackMem has moved from the coresponding Java folder in C:\Program Files\Common Files\Research In Motion\Shared\Loader Files\8310-v4.5.0.69_P2.7.0.72.

I would be very interested to learn if CrackMem is able to sfift files in an out of the RemovedFiles+OS folder when you select a module to remove and then use Put It Back.

Pete:

This is really strange. The REMOVED FILES subfolder contains another folder [8310-v4.2.2.194_P2.5.0.44] and the vendor.xml file. This, obviously, was from the previous OS on my Curve. The [8310-v4.2.2.194_P2.5.0.44] only contains two files:

net_rim_bb_medialoader_video_83xx_320x240.cod
net_rim_phone_tty_enabler.cod

Yet, despite the contents of the REMOVED FILES, the BB DM did install the 4.5.0.55 OS on the phone.

FWIW, there were only two versions of the OS on my PC - 4.2.2.194 and 4.5.0.55, and the install was done from the C: drive.

Hope that helps... and as I said earlier, don't completely discount the possibility of operator error.

I had a decision to make when I designed CrackMem. SHould I completly clean up after running and delete any folders (and their contents if the user did not use Put It Back) or, shoul dI just leave the RemovedFiles folder in place with whatever it contained.

I opted for the latter and persued a policy of 'never delete anything'. The logic was that if I deleted stuff, the user would then be unable to ever use a pristine OS again. The downside is, as you have discovered that if you delete and OS from youe system after you have ever used a Remove module with CrackMem then there will be a RemovedFiles folder + an OS folder (in your case, this was 8310-v4.2.2.194_P2.5.0.44.

At some time I geuss that you had this OS on your PC and used CrackMem and then deleted the OS. This would have left the folders and the files on your disk.

Each OS is kept in its own folder so that the files don't get mixed up. The exception is Vendor.xml which is overwritten in the AppLoader folder each time you install a new OS and is outside my control.

If yo have two OSs install for your phone then Desktop Manager (not CrackMem) will always install the latest valid OS on your phone. This if you have an 8310 (my own phone) and have OS 4.2.2.194 and 4.5.0.69 installed then to upgrade, you just run CrackMem, remove Vendor.xml (as a minimum) and then run DM and that will install .69. To downgrade you MUST uninstall .69 from your phone and then insure that Vendor.xml has been removed prior to trying to downgrade to 4.2.2.194. Which is now the higiest valid OS availabe for installation.

I am sorry that thos post rambles and you are probably going to have to read it a couple of times but I really did want to fully explain what decisions I made and how they are implemented.

Using CrackMem is a little like tryong to butter a sandwich after your have made it. It slides in after installing the OS on the PC and running DM. RIM never planned on CrackMem existing - what bad planning.

Pete:

Thanks for the explanation. What you say makes sense, and I totally understand the choices and why you chose the way that you did. It makes perfect sense (and it's early and I only had to read it twice ).

I had tried to install the 4.5.0.55 release once prior - an upgrade which went horribly wrong, largely due to that surreal theme. The initial install (for which I used CrackMem) died about half way through with the dreaded 523 error. (Background: I had installed OS upgrades in the past, but none had ever gone wrong. The surreal theme on 4.2.2.194 was a 'special' theme - and the documentation/PR page warned about using it on 4.5 releases. I was aware of that, and changed the active theme to one of the default 8310 themes prior to attempting the upgrade... but the App Error 523 Reset error problem came from the fact that the theme was even on the phone, and the upgrade puked all over my 8310 when it found the invalid application, as it called it.)

Anyway, I ended up wiping the device (JL_cmdr), removing the 4.5.0.55 OS from my computer and reloading the 4.2.2.194 operating system. Once everything had settled back to normal, I decided to try again. I reinstalled the 4.5.0.55 OS on my PC, ran CrackMem and did the install.

I said all that to show that this particular upgrade event was frock with errors - mostly of the carbon based variety. It is totally possible that the add/wipe/remove/reinstall process confused CrackMem - it certainly confused me

At any rate, I don't blame CrackMem at all for any of my issues... and after having this discussion, I fully understand what is supposed to happen, how/why it does what it does, and I will most definitely be using CrackMem in a more 'uneventful' upgrade attempt next time.

Thanks again for your time, your explanation and for creating CrackMem.

Pete, thanks for the good work!
CrackMem 2 works flawlessly under Vista x64 for me.

Sweet App!! Thanks!!

testing this app on my 8310 will post later what i think about it so far real good and gain memory.

CrackMem 2 looks and works great. Thanks so much for your work on this.

Pete:

I wanted to post a 'followup' to this saga. As promised, I gave CrackMem another shot and it performed flawlessly.

I used it to decrapify the latest 4.5 (4.5.0.92/4.5.0.69) for my 8800... and it did exactly what I wanted/told it to do.

I am 100% certain that my previous issues with CrackMem were extensions of the other OS upgrade/install issues that I encountered, and that I managed to confuse CrackMem with the installing/uninstalling/reinstalling of the OS upgrade.

Thanks for the tips, explanations and the great software tool!

Hi Pete,

Sorry if I missed this somewhere in the thread (this has become a fairly lengthy topic).

When removing VAD does CrackMem give you the option to remove only the files for specific languages? I use VAD every day but I need only the English files so my routine when updating my OS is to remove the VAD files for all languages except English.

I actually go through and remove all the .cod files for all applications relating to other languages (anything with suffixes _fr, _es, etc) just to get things as clean as possible. It would be cool to have that option built into CrackMem.

I believe the loader only loads language files that match the requested language/default language. So, for example, if you don't load the Spanish language files, I believe the loader bypasses ALL of the _ES_ files for any application.

i have installed this app on my pc where i also have Bb desktop software etc, but i get an error saying that it can not find an OS.
any suggestions?
thanks

I used this today on 8130 4.5.0.77 and for some reason it didn't delete the Vendor.xml file...I'm sure I selected that as I selected it in the crackmem screen, but after I executed the changes and exited Crackmem and ran Apploader, it didn't see the new 4.5.0.77 OS.

I went and manually renamed the file and re-ran apploader and it worked fine...

The last time I used Crackmem on 4.5.0.66 I thought it worked fine, so this is strange.

I know why thi happened and there is a bug in my software. I am very sorry. The bug is now fixed in v2.7 and I shall post that here as soon as I have finished my reply here.

The bug was that if there was a copy of Vendor.xml in my RemovedFiles folder and there was one in the Apploader folder then CrackMem was unable to remove the file from Apploader. This is because I never actually delete anything and the program did not know what to do. I have now fixed this by really deleting the copy of Vendor.xml in RemovedFiles if you are trying to remove Vendor.xml from another OS. Tis way the latest copy of Vendor.xml is preserved. This is the only time that I ever really delete a file in CrackMem.

I am sorry that your were inconvenienced.

I just put up CrackMem v2.7. The main change is a new function to rename the DocumensToGo.alx file to DocumentsToGo.old. This function is of use to users who run DocsToGo from DataViz Corp.

DocsToGo is distributed with a number of later OSs and will installs a limited functionality version. This may be upgraded OTA for free from the DataViz website. A further, paid upgrade offers full functionality via the Premium edition. This upgrade is either OTA or downloaable via a zip file on request from DataViz.

However if the upgrade is applied and then the BlackBerry is conected to Desktop Manager whilst the OS remains installed, DM will immediately uninstall all the DocsToGo upgrades. I contacted DavaViz via email and they have told me that their approved remedy for this is to rename the DicumentsToGo.alx file to DocumentsToGo.old.

Personally I think that this is a real kludge for a compration to tell a user to rename a file inside the Program Files folder.


The gray subpanel is the part that handles the rename.

Select one or other of the two radio buttons and press the DoIt key. CrackMem will tell you what action it has taken. If you try to rename the file that has already been renamed, Crackmem will says so.

You can make this change at any time - either before or after OS instalation.

Remember that this option is only valid for OSs that have DocsToGo included. The rest of CrackMem works as before.

thank you!good!

Thanks a lot!

I used Crackmem and when I wanted to wipe my BlackBerry
I entered an incorrect password 10 times and now my BB won't even start or connect to any PC..
How can I fix my BB
And what happened?

um why can't it recognize the OS i have in my system? it says i have none installed....

Hi Pete. Sweet app - I just used it to remove a whole bunch of unwanted themes and it worked perfectly. Many thanks

I do love this program! Learn how to use it befire complaining.

queennouni- What happened was that you entered the password wrong 10 times.


WARNING: If you people have no idea what you are doing, do not use this program.


Come on people, get with the program!!!!

Hi there.

I've bricked my Javelin / Curve 8900 multiple times (about 11 to be exact) in 1 day.

I got it from MTN and I have a Vodacom sim in it with BES/BIS loaded.

Using the device out of the box with the Vodacom simcard works fine.

I bricked it using JL_Cmder (classic 507 error) on display and then used your tool to load a more streamlined version of the OS without the operator (MTN's) logo on startup but unfortunately whilst it succeeds in loading an OS (it does not remove MTN's logo)

The device works perfectly though , I've downloaded and installed 3 versions of Vodafone firmware on it as well as one random one from some carrier in South America and again whilst it loaded , I ticked all the options on Crackmem to remove just about everything and then executed those selections and then started a wipe again even after JL_Cmder had its way with the device (just no luck)

I think that Blackberry and / or the operator (MTN) has a different way or procedure to load firmware or they have write-protected some aspect of it on the device (one can brick the phone but whatever firmware you install after bricking it , you get the same version as what was originally on the device out of the box when supplied to me)

For what its worth its an excellent tool (I am going to try it on my test Pearl 8100) anyways.

Loading a different OS will never change the startup splash screen. If you want to "debrand" it you'll have to do a google search on how to "debrand" your BlackBerry. I don't recommend it, though.

Hmm , so after all that I accomplished nothing.

I was under the assumption that the "Remove Carrier Themes" also applied to the startup logo.

My device is working fine so I won't willingly brick it some more.

Out of interest how difficult is it to debrand a Berry with regards to the startup and home screen icons and have you tried this before ?

I did a search on Google and came up with the links for debranding info , quite interesting

I downloaded and there is no operating system.
Can someone help me to fix this issue!
Thanx

I am having trouble with the operating system appearing in the left window....It is empty!
Can somebody help me to fix this problem.
Thanx
Oh, I have 4.5 on the 8100 BBPearl and 4.6 desktop manager.
