M600 Rom upgrade

---

Hi guys before I start, I have read numerous posts and tried to do as much reading before writing this, but my findings are not conclusive.

I have just got a new M600, so it’s locked to Orange and has no rom alterations done.

I want to upgrade my rom as I don’t like the Orange stuff in there anyway and I was very happy with a Qtek rom on my M500.

1 Do I need to sim unlock the phone, to rom upgrade?
2 Can I just upgrade using the files as in post http://forum.xda-developers.com/viewtopic.php?t=49298
3 There’s talk of the CID being unlocked, does this need to be done, before upgrade.
4 There is no sure way of backing up existing rom?.
5 Once upgraded, is the phone still sim locked.

Basically I don’t want a brick sitting on my desktop.

Regards

Up!

I too want to update my Orange France SPV M600 freshly bought this week but i don't know if i need to CID unlock the phone before upgrading with a Qtek rom.

And another n00b question: is there a list somewhere with the new features of the roms ?

Thanks in advance ^^

I too want to update my Orange France SPV M600 but my Orange France SPV M600 is now in 3 line color and numberis: IPL 2.10.0001 and SPL 2.G3

Reading the XDA-Wiki, you can see that a CID unlock is required for doing anything with ROMS. As a result, if you have a G3 phone, which you need to check, then follow the instructions here

If you have a G4 prohpet, then unfortunatley you cannot CID unlock the phone, thus no ROMS.

SIM unlock isnt required for ROM upgrades, but the CID criteria must be met.

Once again, if you had read the wiki, you would know that ROM backup is available here

Hope this helps,
