This release is only for the 8700 (8700g, 8700c, 8700r, 8700v) series. It is not for the 8707 (8707g, 8707v) series. These devices require a different firmware release.

Thanks for the update, I'll make an attempt to install once it finish updating!

Thanks for the version 4.2 update. My 8700c was becoming a dinasour very quickly. Funny how a bit of software can totally change the versaility of a Blackberry!!

a few months ago i was a palm pilot man! I had a zire 72, but i was trying to fix the steam where the charger plugs into by soidering it. I put it back together, and bam! it was not working, maybe some solder is touching some where that caused a short circuit, so i moved to the black berry 8700, it was on sell for $200.00 used with a prepaid sim from ezlink and 200 min. i wanted it for blue tooth experiments, but it does not have the same quality as the palm. I was going to find another one and drop the black berry because i dont have a data plan. and with the zire i could get on the internet using bluetooth in my home, it was great, now finding a way to connect my blackberry to the internet using usb or bluetooth would be kool! im not talking about using the blackberry as a modem, but logging on the internet with my blackberry with usb or bluetooth to read my mail, and surf the web while im down stairs on my sofa, feel me! doing it with out a data plan, using my computer as the server. wirless or bluetooth. if anyone know of such a program please email me at redwar_888@yahoo.com

Two words...THANK YOU!

We have a unified messaging system that limited our ability to use it since 4.1 didn't fully support the wav file attachments. Mucho grachias!!!!

were do i find the vedor thing to delete

This is deliberatly left unclear. If you cannot find a file on your Windows machine, you should not be using an unsupported firmware.

Volker Weber, 2007-05-26

i' d like to know how i can disable the restriction of use with a specific operator my 8700g from blackberry. i got italian vodafone sim and my telephone is actually working just with tim operator sim.

Hi there,

I am currently running Vista business and I am trying to upgrade the 8700g to 4.2.

I am slighlty confused about the rom update? What is this? Is this the 4.2 version that I have downloaded!

Also the Vendor.xml file is that on the Blackberry or the PC?

Thankyou to anyone who can help!

I just popped a search for firmware updates for my 8700 and got this site -- simple and to the point; Thank you! Installing the update now.

ORen IshiE, 2008-06-16

Had some difficulty locating the vendor.xml. Finally found it under Program Files\Common Files\Research In Motion\Apploader.

After deleting it it would allow me to update my 8700. Tnx m8's!

I have a blackberry 8700g there is no browser available how can i download browser and surf on the net ,read my mail?

Erol bicaci, 2008-10-17

Hi' everyone,

Not long ago, I undertook this update on my BB 8700g. However, after it had completed, the handset simply displays a red light and tries to restart. Showing the hour glass for about five seconds, then does the same thing all over again.

Just to see how long this would go on for, I left the handheld for several hours, however, four hours later still restarting.

Any advice on this, would be great. Thank you in advance.
