Just a little unsure if I should attempt the upgrade. How much of a risk ... BlackBerry Curve forum
8300 upgrade to 4.5 - is it worth the risk?
Just a little unsure if I should attempt the upgrade. How much of a risk would I be taking and is it worth the trouble? Any advice would help. I have ATT so there is no official OS for me but Ive heard the vodaphone australia works. Please help
Hey cbarry! Welcome to PinStack! Well, to posting anyway!
Risk/reward ratio is way heavier on the reward side. While there is, of course a risk of horking something up with any upgrade, it really is pretty easy to do and trouble and/or issues are more the exception than the norm.
So if any of that made sense, bottom line is that if you are comfortable with your device and performing the upgrade, then by all means go for it! Surely you've seen that there is a wealth of knowledge here on PinStack to assist you every step of the way!
Its definintely not risky if you know what youre doing.
Just make sure to follow this STEP BY STEP:
Here’s a quick How To on installing 4.x.
Follow these instructions exactly and you should be able to have OS 4.x working.
1.) BACK UP YOUR DATA! - I can’t stress how important it is to get a good backup in the event you need to restore your data.
2.) Verify that you are using the latest version of Desktop Manager. Open BlackBerry Desktop Manager. In the Desktop manager program on your PC use the Help menu and select About Desktop Manager. If you need the latest version follow this link.
3.) If you haven’t already, download lastest OS 4.x from this link or if available from your carrier its BEST to download here (select carrier)
4.) Install 4.x using the .exe file you just downloaded. If you are downloading the OS specific for your carrier you can skip step 5. I other words if upgrading a T-Mobile BlackBerry with T-Mobile OS then you can skip this step. However, if you have an At&T Wireless Blackberry and the OS is non-At&T eg. from Vodafone, you MUST follow step 5.
5.) Delete the ‘Vendor.xml’ file ( C:\Program Files\Common Files\Research In Motion\AppLoader ) Or search your computer’s hard drive for the “vendor.xml” file. Once you find it, delete it.
6.) Connect the BlackBerry device to the computer. If prompted, type your BlackBerry device password and click OK.
7.) Open Desktop Manager. It should recognize that there is an upgrade for your device. (’Vendor.xml‘ must be deleted for this step to work).
When the Application Loader Wizard is finished examining the configuration on the BlackBerry device, the Device Application Selection screen appears listing the applications and OS version available for installation. The selected check boxes indicate applications that are already installed on the BlackBerry device.
9) If you didn’t backup first you should select to do so now.
10) Follow the prompts and you will have OS 4.x installed in about 15 to 20 minutes.

4.5 is really rewarding as you feel like you have a brand new device.

There is really no risk only uncertainty. The 4.5 upgrade is hands down a better OS than what you are currently on. If you use your 8300 to your full potential it will be like giving it new life because it improves on every area as a whole on the device.
*Larger storage capacity
*More Calendar features
*Advanced Media Player
*More Detailed Browser
*Video capability(8310 not sure bout 8300)
These are just a few new features that I can think on top of my head. I think you'll be very satisfied with the upgrade. The best part is since you are on this forum there is plenty of people that are willing to assist you on your upgrade. What more could you ask for?
Ranx, it was posted by a Stacker by the name of twheeler, nearly 3 years ago!
~via BB (wap.pinstack.com)I have at%t my self.and it sucks that we dont have an upgrade yet,but I took the plunge yesterday and went up to 4.5 Rogers.and so far its going preaty good.I was use to my old os but I think iam getting the hang of it.its got a little more stuff then my old one.vid camara,youtube,and I feel the browser is a little faster.but maybe that's jus me,go ahead and give it a try.I was hesitant at first.but got tired of waiting.let me know how it goes
This is the killer question for me.. What if i want to go back to 4.3 (my sprint 4.3 to be exact), and im using another carrier's 4.5 os (say t-mobile)? whats the process to downgrade? I would take the plunge if i can get the instructions..
Downgrade instructions are pretty much the same as upgrade instructions, the only difference being you would need to uninstall the 4.5 OS from your PC. Once you've done that (with the 4.3 OS safely installed on the PC), Desktop Manager will compare what's on your device with what's on your PC and see the difference, prompting you to downgrade.
Hope this helps!
Well then Credits go to Twheeler for this great tutorial!

If you do need to downgrade, you'll be putting the Sprint OS back on your device in which case you needn't delete the vendor.xml file, but the 4.5 OS MUST be removed from your PC.
Control Panel>Add or Remove Programs (or Programs and Features if you're running Vista).
You'll see BlackBerry Device Software 4.x. You'll uninstall the 4.5 OS if you need to downgrade.
ahhh, ok. I was thinking about desktop manager. And i was wondering "if i get rid of desktop manager, then i cant do anything". That make sense with what you guys said.
So, OS 4.5 is an application i must install on my pc also, for the upgrade, and then with deleting the .xml file, DM will think my phone has an upgrade? right?? And by me deleting the 4.x OS from my pc, DM will think that i dont have the correct os and it will find and install it for me which is 4.3, right?
When i back up my phone, after the upgrade, will all of my settings be on my phone already? or will i have to use my backup to place all of my settings and stuff back on?
You will need to download and install the OS you want to downgrade to but yes that is basicly what they are saying. If you dont have the 4.3 downloaded and installed you can get it here.
