I ve got a bb 9900 on o2 network running os7.1.0.342. Should i updateto 569 or is it not worth it? , or is 342 the best build

.569 is much better, plus you get the application resource monitor

I've done still doesn't detect the new oswhich am trying to install

Have you tried using the desk top manager software? That how I update to a new OS. As long as you delete the vendor file the software will recognized the OS.

[misbah_786]

Well I searched for both of the vendors and deleted then used aploader then it says sucessfully installed after a second

[RoseBud68]

Again have you tried the Blackberry desk top manager to load the OS. Please re-read my last post.

[misbah_786]

Yes I have it doesn't detect it on there

[RoseBud68]

Thats because there a vendor file that need to be deleted.

[misbah_786]

I deleted both of them, btw am on o2 uk carrier can I usethis republic 569os update

You can use every 9900 OS with your 9900. It doesn't matter whether this new OS comes from carriers out of Thailand, Japan or Costa Rica.

To double check:
Have you successfully uninstalled your device software on your computer and did a reboot?
Have you then successfully installed the new .523 software afterwards?
Have you double checked that both RIM vendor.xml. Have been deleted? On my PC I have another application installed which features a vendor.xml file...
Have you tried to wipe your device with a tool like BBSAK?

By the way I never needed to use a registry cleaner. However it is important that you uninstall your previous firmware and do a reboot. Also deleting the right vendor.xml is simply important. I always update using the BBSAK wipe then reload the new OS via loader.exe - never had a problem with it after the first time. The first time I forgot to delete the second vendor.xml file and had similar problems like you do. However I updated twice since then without any flaws - both .523 and .569.

There's a program called vendelte+. Grab that, as it deletes RIM vendor files, and use BBH Tools to wipe and load your new OS. Just make sure it is for your device! [the OS]
