CID Unlocking

[d0ug]

I know there is no free utility yet to CID unlock the G4 devices. Those of you that have unlocked your G4's at the IMEI-Check site http://www.imei-check.co.uk/m3000unlock.php Is this just a SIM unlock or also a CID unlock?

If it is a CID unlock are you now able to make a ROM backup using the R2SD method shown in post 8 of this thread? http://forum.xda-developers.com/showthread.php?t=258819&highlight=r2sd+backup

This is my main reason for wanting to CID unlock. I want to be able to make a full ROM backup with this method, before trying any new ROMs. My CID locked 9100 gives me this error "You didn't get the proper security level to download a specific image" when I try a R2SD backup

Go ahead and you will be able to do r2sd backups and restore after CID unlock at imei-check.co.uk.

So does this CID unlock the phone if it's a G4, you're a bit unclear?

IMEI check is SIM and CID unlocking. If you are gonna do it, see my post here (http://forum.xda-developers.com/showthread.php?t=284312).

yes... using the method availble at imei-check.co.uk will very much CID-unlock your device

NOTE: There's been a lot of posts regarding this subject but the fact of the matter is that you do in fact get your phone CID-unlocked at this website despite what you may have read in other threads...

What are the security or other implications of handing over my IMEI to them? Is that safe?

No worse than handing over your credit card info to them.

IMEI Check is a reputable company, and doing what they do, it is in their best interest to safeguard your information. Also, I've never seen any complaints against them that weren't about how much they charged for their service.

They DO intimate that they can re-lock your phone remotely if you back out on payment, but if you deal in good faith, I don't ever see that as a problem.

Of course, YMMV, but probably not.

Hi,

I've heard that my device will be CID locked again after applying one of the ROMs. Does this mean I have to CID unlock my device again??

Just to be sure I can restore my backup ;-)

I've already paid for the CID unlocking, but it seems that the extended rom specifically NEVER installs. This, to me, seems like its not unlocked if that isn't working, or at least not fully unlocked. I've run the unlocking tool (from imei-check) 3 times now, I believe, and installed many different ROMs.

How can you CHECK if the unlock worked on a G4?

moonrock You may check CID having started Prophet in mode bootloader and having started mtty142 and take command info 2 - You see your CID.

imei-check does not do unlocking ExtROM this absolutely area miscellaneous.

moonrock .....having started mtty142 and take command info 2 - You see your CID....

Check this thread http://forum.xda-developers.com/showthread.php?t=290831 where it's explained what arc is talking about in first paragraph ;)

Second paragraph means that ExtROM isn't unlocked by IMEI-check because it's an independent partition of the DOC chip which is write-protected in G3 2.xx and all G4 :mad:
