Downgrading Firmware?

To my knowledge there is no way. sorry man.

Oh well, looks like I have to wait for an 02 version of V20 to be released before my warranty is up.

I will also try a re-install of the v20 firmware.

Has anyone experience of taking a debranded phone in for repair under warranty, I assume there is no chance of it being repaired under warranty?

dog-man 😮

The last I checked v12 was the newest o2 firmware. Since I changed my product code, for all I know, they may already have v20 out.

I may have remembered incorrectly the version, but it definitely was not v20.

I've taken mine for repair twice, both times running debranded firmware despite a t-mobile handset, and both times fixed with no problems.

You can downgrade firmware with JAF or some other type of box.

JAF?

What is this?

Don't bother, downgrading is risky and pointless. Many of us on here have had repairs done with 'incorrect' firmware and no one has ever said they had any problems with warraty

I have googled 'JAF'.

I am not sure that I actually have a fault with my phone.

It's just that it won't connect to my university 'eduroam' wlan even though other N95's do with exact same settings.

I have corresponded with Nokia who suggest there may be a fault as it should connect with no problems and they also deny any known bug within the latest firmware that would cause me not to connect.

This has been suggestd on here by some N95 owners.

if you change the product code back when you connect to nokia software updater for updates it'll let you install the latest software for you real product code
it'll tell you the latest software and ask you if you want to install ect
i dont think there should be any problems b/c it'll be just like installing any other update

If you're taking your N95 to a Nokia Repair Centre I can't see why the installed firmware version is of any relevance. After all, you've got an official Nokia firmware downloaded from the official Nokia Software Updater, the very same software Nokia advertises and provides for users to update their phone's firmware with.

Now O2, on the other hand, might want to be all officious and kick up a fuss if you were claiming something with them. They might say only genuine O2 firmware has been tried and tested and if you upgrade beyond that then they can't provide any guarantees your handset will function properly. But even then, someone with just a small ounce of common sense, should be able to see that genuine Nokia firmware isn't an issue.

Even though the version on my phone is v20 and o2's latest version is v12?

the firmware before update does'nt matter b/c when you install a update all that as gone before is deleted and over written

just search about it on different forums b/c you need more opinions on this than just us few on here who are giving conflicting info
i
f you took it to a o2 shop to be fixed all they would do is install the correct software for it

even if you dont reinstall the o2 firmware,its still best to change product code back even if you are still running a different firmware

I have now changed the product code back to the original and tried a firmware upgrade.

It won't do it. I am told I have the latest version

I believe that the latest firmware for o2 is v12, not v20. Can anyone confirm this for me?

dog-man

the v20 must of been made availabe for o2 b/c alot of branded firmwares was released 2 days back

tell me you product code i'll do a check

0548021

i just tried checking but the update check is not working it says its down for maintenance
when ever they do this they add firmware updates
i think its been made available i'd just try it out if you've had problems with the firmware you got installed any way

or wait until later for 100% availability

I'm sorry but I have to take issue with you a little here ccraig. You are giving a lot of incorrect info and bad advice.

Not true. Nokia Software Updater will not allow you to install an older version of the firmware regardless of product codes, this is a fundamental Symbian Security policy.

You are the only one giving conflicting info, and it is wrong.

Why?

If you have problems and have the latest firmware, do a hard reset. This wipes eveything back to factory and thus leaves your phone in the same state as if you reinstalled the firmware but saves a lot of time.

You cannot downgrade (not safely at least). I ran NSU with my t-mobile product code after upgrading to unbranded V20 and it said "no newer version found". This is fact! The only ways to downgrade are risky and WILL invalidate your warranty, not to mention potentially bricking your phone.

I have also had my t-mobile phone repaired under warranty on two separate occasions with a Nokia Service Center, both times with unbranded firmware and the EURO1 product code and both times without any problems or questions despite the phone clearly carrying T-Mobile branding on the back.

I'm sure you are just trying to help but your lack of facts is just confusing the issue.

I have just checked the Nokia site again and the o2 latest firmware is >>
Latest available software for Nokia N95, product code 0548021
Version: 11.0.026<<<<<

Not even V12!

I will do a factory reset and try again to access my university wlan when next there. If I fail again using known working settings then I will return my phone to the o2 shop where I purchased it for investigation and possible repair.

Nokia are denying any bug within their firmware that would be stopping me connecting, even though I know some who ARE connecting, but with a N95 8gig with their latest firmware.

why is it best to change to the correct product code after upgrade ?
thats obvious, as you know some shops will not repair your phone if you've changed the product code so its best to change it back b/c if it phone stops working atleast you've got the correct code in the phone for when u take it to be repaired

That's my point though, can you give an example of a shop that has refused repair based on product code?
As I've said, they've never said anything to me and many people on here have had the same experience. I suppose you could change the code back 'to be safe' but there is no evidence to suggest any Nokia Servce Center will refuse it.

I can clear this up once and for all. What's below is the OFFICIAL answer from Nokia:

You CAN NOT downgrade a firmware using NSU, no matter which product code you're using. You can NOT re-install the "latest" firmware for a product code if that version is older than the one already on your phone.

While most shops won't bother which firmware & product code you have on your phone, Nokia WILL NOT repair any phone with the wrong product code / firmware installed.

Changing the product code on your phone INVALIDATES your warranty. If Nokia catch you having done this (i.e. you try getting a phone repaired with the wrong product code / firmware) they are within their right to refuse to fix your phone.

When taking your phone for repair, it is ALWAYS a good idea to change the product code back to original, even if the firmware version is "newer". Most shops will then happily re-flash the phone for you in a way which IS within Nokia's warranty.

If you're within London, use a shop called Netcom in Teddington. They understand how / why people change these settings and will change everything back before sending a phone to Nokia.

So, if a phone is faulty or suspected of being faulty, do I return it to the o2 shop where I purchased it, or can I take it to any mobile phone shop?

I would assume it should be returned to the o2 shop?

Try returning the phone for repair, if they do it great. The worst they can do is say no.

If thats the case and you have insurance....you can use that for sure!

You need a Nokia Service Center, not the O2 shop. Go on Nokias website and find your nearest service center.
If you go to O2 they will send it off to Nokia and it will take ages, wheras the service center will repair it themselves if they can and only send it away if necessary. They are also much less likely to care about firmware versions.
Based on that 'official Nokia statement' you might want to change the code back but consider this:
Lets say you have debranded v20. You set the code to back O2. They fix it then go to reflash only to find you have a newer version than is available! That is more likely to flag a problem than if you have the EURO1 product code so when they go to reflash it does so without problem.

OK, thanks for the info.

I have found my nearest repair centre (20 miles away), but will give my phone one more try being as I have now reinstalled the firmware.

I wonder how they would check my phone?

My problem is that it will not connect to my uni's wpa secured wlan even with known working settings as supplied by the uni's I.T. department.

I can connect to my home network with wep easily.

Do they supply a loan phone?

I'm not sure if they do. When I handed my 7650 in ages ago I had my 9110i to fall back on so I wasn't left high and dry. I think *if* you went to an o2 high street shop they certainly would, but not sure about Nokia directly.

I suppose it would depend on how long I was without the phone as to whether I would be bothered not having one or not.

I am not a heavy phone user.
