HTC One X How to Change CID flash a stock rom on branded device

S - OFF to unlock the bootloader , org says there are some common , some say different . Want to know what s the difference ? Someone unlock the bootloader first and then s - off there is also a distinguished without unlock the bootloader lgsg s - off ( with tutorial temproot first )

unlock bootloader = allow flashing via fastboot mode .
fastboot flash recovery recovery.img - > inject recovery
fastboot flash boot boot.img - > inject ato boot images like the kernel called fastboot flash system system.img - > inject system image
S - OFF or we call security off , some require custom rom for S - OFF to install a ROM . Thing we can do if S - OFF

- Free riding down the firmware , from GB to ICS and then to GB again
- Change CID to superCID Number (1111111) , CID = Customer ID Number . ID device that attaches to us . Well Bill files that are available either on xda , another mirror contains a list of CID number , if the CID on the device we have in the bill so we can file reflashing to the stock rom with the bill , but if CID our device not listed in the list of files that are on the bill the flashing then it will fail . To be able to reflashing , the CID number in the device that it has to be changed , via fastboot command . To change this , SIZE S - OFF . One generation HTC and after that use the sense 4.x , there is no s - off . Well if there is an announcement to update the OS in other countries , not necessarily the same in our country . There is the question " why not just use the existing bill on xda ? " , She replied of course not be used for reasons CID number different .

- Flashing ( without PC : via bootloader mode , where the files are located in the P - _ - IMG.zip ) , could it be a recovery , radio or the whole firmware . - _ - It depends on the devices what , some PG58img.zip , some PC10IMG.zip , some PG86IMG.zip

- Replace HBOOT , with the command dd if = / ......... hboot it can go down or up . There are certain HBOOT which if replaced then they will become unlocked bootloader devices , such as Desire Z , Desire HD which unlock not pass htdev.com - Replace splash Lcd banality by writing htc white Lcd background.

- Replace kernel of CAN through recovery or 4ext recovery control application

- When changing the ROM , no boot.img file usually in the custom file romnya . In S - OFF state usually , when we flash the boot.img adherents in contact while still S - ON if we fit the flashing boot.img NOT TAXABLE . Therefore, it must be manually entered fastboot flash boot.img via home PC for TSB

S well - off and unlock the bootloader , the same thing is

- Easy to access root

- Can install a custom ROM , only in S - OFF it all in one with the kernel , in the BL unlock different maybe For HSL same procedure with S - OFF ( first flash kernels or boot.img via fastboot , new rom ) . Rada not feeling well past ganti2 mo rom dikit2 should open PC For flash boot.img first

- Can attach different way to recovery though , that s - off via the bootloader ( without PC ) , which unlock BL via fastboot mode ( with PC )

Prerequistes:
Unlock bootloader.
Rooted
Working Adb.
Hex editor.

1. Fire up your command prompt and go to the directory that you have ADB installed to. Type "adb shell" and hit enter.

2. Type "su" and hit enter. You now have root privileges.

3. Next type "dd if=/dev/block/mmcblk0p4 of=/sdcard/mmcblk0p4" and hit enter. This will dump the partition to your sdcard.

4. Next type "exit", hit enter, type "exit", and hit enter again. This should take you back to a command prompt for your computer.

5. type "adb pull /sdcard/mmcblk0p4" and hit enter. NOTE THE SIZE OF THE FILE BEFORE THE NEXT STEP!

6. Open the file (mmcblk0p4) with your hex editor.

7. Look for offset 00000210 and you should see T-MOB005 with your IMEI number attached to it.
( MY CID WAS T-MOB005 YOUR MAT BE DIFFERENT)

8. Change T-MOB005 to HTC__001 and save the file as mmcblk0p4MOD. This will give you SuperCID as well but instead of HTC__001 you have to put 11111111.But I think supercid does not get OTA updates. So better stay with generic HTC cid.

MAKE SURE AT THIS POINT THAT THE FILE IS THE EXACT SIZE IT WAS BEFORE YOU HEX EDITED IT!

Remember change 8 numbers with 8 in your cid and do not delete the IMEI make sure you match it before going forward

9. Now go back to your command prompt and type "adb push mmcblk0p4MOD /sdcard/mmcblk0p4MOD" and hit enter.

10. Type "adb shell" and hit enter then type "su" and hit enter again. This will put you back into the android shell and give you root privileges.

11. Type "dd if=/sdcard/mmcblk0p4MOD of=/dev/block/mmcblk0p4" and hit enter.
To test if it worked restart the phone into fastboot (type "adb reboot bootloader" and hit enter) and once the bootloader Lcd comes up type "fastboot oem readcid" and hit enter. It should read "HTC__001".
Now flash a stock recovery and stock boot. Relock your bootloader.
Run a stock rom. Just rember to unlock your boot loader again you will need to run fastboot oem get_identifier_token again submit to HTCdev and get a new file Do not use the previous one. Hope you have all the files need if not look on the other post or let me know will upload them.
