bought a Bold 9000 for my sister and updated it to 5.0 and two days later when I pulled the battery to switch SIM card the phone refused to boot. Only red led and nothing else. I took it to service and they said that some versions of Bold 9000 should not be updated to OS 5. Ive never heard of that, is it true? Cuz I payed 15eur for them to bring it back to life and its running 4.6 but Id like to update it back to OS 5. Should I do it again?

I have never heard that being a problem. However, the 9000 was made for 4.6, not 5.0 so there could be some memory issues but I don't think this is the problem.

Why do you feel the need to update to 5.0? What does the device not do that she needs it to do? Given the past attempt, if it works the way she wants and needs, it isn't broken and therefore does not need to be fixed with an OS upgrade.

It could have been a corrupt file, incompatible app, or incompatible theme causing the problem.

I might be misunderstanding the issue but Rim does indicate OS 5+ is available.

Also the MTS does offer a download with this version.
This is from their site

Only you can answer that. But here are some questions to help.

- Are you ready to pay 15eur again to have it fixed if something goes wrong?
- Is the device working with 4.6?

As Dubdub already said, if it aint broken, don't try to fix it.
