Well, I would rec to start with the latest OS for your 9520 device. You can download 5.0.0.1077 here... VodafoneUK_9520_5.0.0.1077 - Downloads - BlackBerryOS.com

Let us know how the installation works for you.

Dear Friends,
I have a strange encounter with upgrading BB9900 recently.

I have bold 9700, 9780, curve which running OS5 & OS6 accordingly. now, I have been following closely your "how to" guide all this time and it works for these devices.

However, it doesn't work on OS7. Not sure if this is only my experience. let me elaborate below:

for some reasons, afterI wipe out my 9900 to clean install using BBsak, the apploader fails to recognise my 9900 afterwards.
it is as if there is nothing is connected! my guess is that somehow os7 has different ram (or rom) config which gets deleted/wiped when using methods above.
As I said, I hv been doing this on os5 and os6 and all works.
this is the first time I did clean install on os7 and the process "nuke" my 9900.

I did all methods which friends had mentioned in the forum (delete all files, uninstalls previous ver, restarted my laptop/pc .. u name it) but none works. I have no choice but to bring to BB centre.

I paid close attention to how they "revive" my bb. surprisingly, they have had to "fish" the info inside the ram (or rom) while the BATT is plugged out :Eyecrazy:... that has to be down around 3 times... then it works... the apploader now "recognise" my bb again..

so, from now on, I NEVER wipe clean my os7 .. just update it with newer ver... it works thus far..

regards,

That sometimes is an issue with OS6 devices. I believe that the how-to was written for OS5 devices. I have been upgrading different OS's to my Torch, always skipping the total wipe section. I feel that, as you discovered, devices with OS6 & OS7 need to skip that step.

My advice is to read through the entire set of instructions first...Understand what you are doing before you attempt it.

Please ask questions after you have read it, but before you start. The staff or myself will walk you through any issues you have.

I assume you are following Post number 4, Loading an OS?

Start from the top of that post and follow it carefully. Click the link to bring yourself back to that post now...

Thanks and good luck

If you have everything but a vendor file, it should be fine....you delete it anyway.

thanks for putting this together it as helped a noobie very much.
