I’m new to SE Phones and the whole unlocking debranding, but I’ve been trying to read quite a bit. I recently purchased a slightly used Z710i which was locked to Fido. I was planning to unlock/debrand it to use with my Rogers plan which I still have a year of commitment.

I unlocked the phone with GSMLiberty which seemed to go well, but now the phone has an unusual problem. The display shuts off when you close the clam shell or when it goes into screensaver mode. I have to shut the phone off and turn it on again to get the display back. I was hoping that when I debrand it, it would clear the problem. At present it is at CID49, would it help to upgrade it to CID50/51? What is the best program to use to bebrand/upgrade, XS++ or SETools Lite?

Any help would be appreciated. Thanks.

Flashing again will probably fix your problem.
XS++ is your best bet. Place a generic English firmware into the "files_to_upload" folder (look around on the net)

P.s. Trust me even though I'm a n00b! I've had experience

Thanks for the help, Alexandra. Should I just reflash the same as the original Main + FS at CID49, or should I look to upgrade? ie to CID 50/51?

To be honest, I'd flash with the latest generic firmware.

Get the latest firmware but stick with cid 49.

I’ve managed to re-lock my phone.  I used XS++ V2.0 and Z710_R1EF001_MAIN_GENERIC_CN_RED49 & Z710_R1EF001_FS_AMERICA_2_RED49. I backed-up the GDFS before I started with XS++, then flashed the Main & FS. The phone restarted and no longer shuts down when I close the clamshell, but it gives me the Insert Correct Sim Card message. I tried to recover the GDFS that I backed-up, but it didn’t change anything.

I think the problem might have something to do with the fact that, after I unlocked the phone,  it indicated NETWORK: LOCKED (when read with SETool). It worked with my sim card on the Rogers Network even though it was previously locked to FIDO.

Is there anything I can do to restore the unlocked condition or do I have to unlock it again?

Wow, I need direct opposite.  How do I unlock my phone from AT&T/Cingular, so I can use it on T-Mobile?  Flashing and custom packs didn't help.  How did you do it?  Thanks for sharing!

As I said in the first post. I used GSMLiberty. Assuming you are looking to unlock the Z710, they use the DCU-60 USB Data Cable that comes with your phone and the cost is nominal ($13.00). Also it can be done in an evening (mine took a few days because, they didn't send my username/password when they processed my order). I am not aware of a free system that reliably unlocks the SE DB2020 phones. Hope this helps, Good Luck.

Well I have been working with the GSMLiberty techs to resolve the problem. They appear to be applying a patch to the firmware to unlock the phone. I had reflashed the Z710_R1EF001_MAIN_GENERIC_CN_RED49 & Z710_R1EF001_FS_AMERICA_2_RED49 Main & FS and I flashed the Z710i_CDA102651_7_R3A_Generic_Trade_USA  custpack, because I understood that you need to add the correct custpack to ‘finalize’ and I was hoping to get my phone’s files to the same CID and region.

GSMLiberty gave me an additional unlock code (free) with instructions to use both the MAIN and FS RAW files I used their Z710a_CXC1250434_NAM1_R1EF001_Red49 & Z710i_CXC1250436_America2_R1EF001_Red49 files to unlock my phone. Everything seemed to go well with their DClient software not reporting any errors. However, my phone now displays the following error message "Configuration error. Please contact your service provider or service center."

I give credit to the GSMLiberty techs as they are still patiently assisting me and I’m not in dire straights as I have my old phone that I can use while I sort this out. I’d just like to start using my ‘new’ phone. Is there any chance that I still have a conflict between Main/FS & my custpack? If I flash a different custpack does it risk changing the patch and relocking my phone? I wouldn’t think so as I understand changing the custpack is part of the fun that everyone is having with these phones.
