Just bought a used X7500. Need help!

[alui]

The seller said it is unlocked. How can I verify it?
I read CID Unlocking and Sim Unlocking. How can I confirm both.

Also, how can I tell which version of the radio?

and which version of SPL (3.5 or 1.2)?

Or is there any great tutorial I can setup for the AP4?

I am starting to get confused.:confused:

the seller probably was not lying as it is easy to do (thanks to olipro - cmonex/olinex) but if you want to check, press and hold your camera button, whilst doing that press the reset button, and tell us the details on the rainbow screen.
this will also tell you if it is SPL 1.1-1.2 or 3.5

when your done just press reset again

LOCKing is related to SPL. SPL is a part of the "bios" (just to use the PC paradign IPL and SPL are "extended bios" :) ), then you have the RADIO section of the rom and the OS (WMxx)

Other part of the rom are the EXTENDED ROM (where the file needed for operator customizzation during first install are stored) and splash screens (a FULL ROM means IPL,SPL, SPLASH 1, SPLASH 2, RADIO, OS, EXTENDED ROM).

This "bios" , called SPL can receive commands from RUU (Rom Update Utility, the sw used to flash the rom file). ROM info are "wrapped" in a .nbf file and the RUU, interacting with SPL with some batch commands, flash into the device memory the ROM parts (Splash are flashed in their locations, os, radio, ....) RUU opens the .nbf file, read abatch command file, and send the commands to the SPL to flash the rom sections

Now you can understand how a custom ROM is done: using a "kicken" you can prepare a .nbf file containing the data and the batch command file used by RUU to flash it in the right location of your ROM (SPL, RADIO, OS, SPLASH, or all together) SPL is a KEY part for this process.

With the stock RUU IPL and SPL some controls are done before flashing, first of all device's language and vendor ID, so called CID. If they doesn't mach with the ROM file you will have an error and RUU exits: wrong language, wrong vendor, ....
Flashing a custom SPL you avoid this check (or it sets the CID to "supercid", it means I accept every language and vendor ID)

The SIM unlock (phone working with all SIM card) needs something more complex. In the ATHENA FORUM whe have ATHENA UNLOCKER, from OLIPRO, for SIM Unlock and CID Unlock and ATHENA WRAPPER, just for CID unlock. They will update the HTC SPL to OLIPRO 1.2

Hi sergiopi,

Your post is so concise. You told us the whole theory it may take me more than a day to find. You have the potential to be a book author. Thanks anyway.

Questions:
1. How can I tell whether the sim is unlocked?

2. How can I tell whether the cid is unlocked? Or it is no harm to run the ATHENA UNLOCKER again?

3. What is the different btw SPL 3.5 and 1.2? Should I update it? I am planning to run the AP4.

Thanks again!

To check if your Athena is SIM Unlocked take a SIM from your friend's phone who is in another network and put it in your Athena. If it refuses to accept the SIM then it is locked and you have to unlock it. If it accepts the SIM and lets you place a call, it is SIM unlocked and most probably CID Unlocked. To check if it is CID unlocked just do what ice_coffe says.

I didn't miss the post from ice_coffee. My Athena is still in shipping. I just want to get more info first. Besides testing with a real sim card, is there any method we can run from the machine?

Listen Alui. The question numbr 3 shows of your post shows that you are realy a noobie. So if you are still waiting for your new device, do not waste your time but start reading. If you already decided that you want to go for AP4, then did you realy read the AP4 thread from first post? I am almost sure, you didn't.
So please remember, if you do not know what you are doing then you have a big chance to convert your super device into a brick.
And once more, if you browse this forum, you can see how many threads is there, and how many post is in each thread. If you see this you should be sure that you are not the first person here who just got his new device. All your questions were answered many times here so just read and read and after a week of reading start to plan what to do next.
