Hello. I recently bought a Nokia E73 Mode after doing a lot of research and finding that it is nearly identical to the Nokia E72, and since the E72 does not support T-Mobile's weird 3G network I thought this would be a good buy. Now I'm interested in seeing if I can debrand this thing, I have done it before with an old 5310 XpressMusic using NSS to trick NSU to seeing it as a debranded model and updating the firmware. I know there is no debranded E73 model, so I was wondering if there would be a way to use an E72 code and update the phone with E72 firmware. All I need is to know if this would theoretically work, i can always change it back if it bricks, and some IMEI? codes for the most identical E72 model (E72-1 -2 or -3)...thanks in advance!
Mmm, on the Nokia forums I've seen references to E73 3rd party software programs that didn't come installed on my E73, so it's definitely a worldwide phone. Whether it's still a "carrier only" phone, I think, is the question. Without checking just now, I thought the E73 has a somewhat different keyboard layout than the E72, not just a smaller space bar and different-looking soft keys. If this is so, I would be concerned about keymapping issues. But good luck with your project. Personally, I would just be happy to get some non-E73 Nokia utility software pulled off phones like the E71 and put into a new .sis installer.
Well i've tried and failed so far, might try some other things later but maybe you guys could give me some input. NSS refuses to detect my phone, weather i install new or older cable drivers, or the Phoenix cable drivers. Phoenix seems to have the ability to change the product code so I was able to sucessfully change it, but unfortunately I found out newer NSU versions don't read just the Product Code. Downloading firmware and trying to update the phone in Dead USB mode doesn't seem to work...any suggestions? Ideas? Things I may be doing wrong? Thanks.
An interesting development...software update on my E73 displays that there is an important phone update available, and under details it has 052.005: the latest E72 firmware. But it couldn't be that easy...it says you can only update through Nokia Software Update, which does detect it as an E73 :P
How did you do this? My main difficulty is this...Phoenix, JAF, and NSU all report that they detect my E73, I'm having trouble forcing them to reflash the phone in dead USB mode...I can change the product code and other production information succesfully, but apparently the latest version of NSU doesn't just check the Product Code anymore...and Phoenix 2010 won't allow me to open my device as RM-530, it keeps saying "Please select RM-658". Any ideas?
I unlocked it from a guy found through ebay. Though transaction was done personally. He gave me a code which worked perfectly. Did you got your money returned ?
I believe if you make more attempts, it make its permanently locked
