How to: Downgrade/Debrick PlayBook from Beta OS 2.1.0.840
- Update: While I have not personally tested it, I've heard that the small update to 2.1 which was pushed out on Sept 24th allows you to downgrade using DM. If it does, awesome. If not, the below method should still work (until RIM blacklists 2.0.1 entirely).
It seems like a lot of people have been posting because they've been having problems with the latest PlayBook Beta OS, 2.1.0.840. Normally this wouldn't be an issue, because up until now you could always downgrade your PlayBook from a beta by debricking it. This is not the case with 2.1.0.840.
When RIM released PlayBook OS 2.0.1.668, they intended that to be the only official OS which people would be able to run; as a result, in 2.1.0.840, they blacklisted 2.0.1.358. When 2.0.1.668 was pulled (whether due to issues upgrading from version 1.0 OSes or issues with the battery levels being improperly detected), there was no official means to downgrade from 2.1.0.840.
There is, however, an unofficial way to downgrade. I've set it up here in a way that it requires very little computer savvy-ness. Keep in mind that this method is UNOFFICIAL, and will VOID your warranty. It is also NOT GUARANTEED to work, and it is NOT my fault if any damage occurs to your PlayBook, your sanity, or your consortium.
This method required using CFP, which is a PROPRIETARY internal piece of RIM software that is not intended to be given to the general public.
ALWAYS BACK UP YOUR PLAYBOOK BEFORE YOU DO ANY OS CHANGES ON IT!
With all that out of the way, lets begin.
Step 0: Connect your PlayBook to a working PC (sorry mac users, I refuse to support your lifestyle choices ) with an internet connection, and have a substantive understanding of the English language.
Step 1: Create a new folder on your desktop. You can name it whatever you want, but make sure you remember the name and do not put anything in it except what you download to follow these instructions.
Step 2: Download a PlayBook OS you want to downgrade to and save it to a folder OTHER THAN the one you created in step 1. Your downgrade choices here are very limited. It is confirmed that downgrading to 2.0.1.668 will work, and you can download 2.0.1.668 directly from RIM.
I suspect that 2.1.0.560 will also work, but I have not tested that.
Download links:
2.0.1.668: http://cdn.fs.sl.blackberry.com/fs/q...873.signed.bar
2.1.0.560:
qcfm.image.com.qnx.coreos.qcfm.os.factory_sfi.GR2_ X_X.560.229027.signed.zip - download now for free. File sharing. Software file sharing. Free file hosting. File upload. FileFactory.com
Step 3: If you downloaded the .bar for 2.0.1.668, rename it to .zip (or just open it as an archive) and extract the .signed file (just the .signed file, none of the other files/folders) to the folder you created in Step 1. If you downloaded the .zip I provided for 2.1.0.560, extract the .signed file to the folder your created in Step 1.
Step 4: Download cfp to the folder you created in step 1.
I do not know where you will be able to find cfp, it is proprietary RIM software. However, I suggest you check This Link created by Lyricidal.
Step 5: (Optional): This step is for people who do not wish to use the command line.
If you are using 2.0.1.668, download this file into the folder you created in step 1: loadOS2.0.1.668.bat
If you are using 2.1.0.560, download this file into the folder you created in step 1: loadOS2.1.0.560.bat
Step 6: If you did step 5, just click the .bat.
If you didn't, just run cfp load osname.signed from the cmd window.
Do not disconnect your PlayBook until the downgrade is complete.
That's it. Your PlayBook should load the OS, and everything should be good to go. After the OS finishes installing and your PlayBook boots up, I recommend you delete any files you downloaded in the course of the downgrade.Last edited by SCrid2000; 09-24-12 at 03:28 PM.

Now, will RIM know you used CFP? Almost certainly not.
Will they honor your warranty even if they did? Probably.
But they don't have to.Hgouck likes this.09-16-12 03:55 PMLike 1 - At would depend on whether you load a debrick or an update .signed.
In other words, back up your PlayBook.09-17-12 03:37 PMLike 0 -
- .560 update worked and put .560 on but still no Android working player. (found out my error for not insalling android player app by sideloading). The nice thing about .840 was that for the first time my Exchange account synced contacts and calendar. The actual way it is supposed o work. I'd been syncing Exchange to Google and then Google to PB for contacts and calendar and had given up on this ever working. Be interesting to see what combination of things I get after all this. Thanks for SCrid2000 for the post and the tools. I couldn't fid any of the needed files before his help.

- Thanks for this post, I had OS 2.1.0.840 and i did a security wipe which resulted in me having no default apps and only the browser available. I tried the downgrade option which gave me an error everytime I tried. It eventually got to a stage where i couldnt even get out of the initial playbook setup cause it was trying to update to OS 2.1.0.840 which is the actual OS on the device. Thanks again, this worked like a charm. Much appreciated.09-22-12 09:44 AMLike 0
