[HTC One X] Serfraz:
Need Some Advice

Excellent Information; I would like to ask a question and some help/advice will be really appreciated if possible after my little info;

HTC One X: Current condition; Rooted, Unlocked (using HTCdev), S-ON, CID: O2___01, corresponds to UK O2 carrier, however it has since been network unlocked with the appropriate code obtained from the same network carrier.

HBOOT-0.96.0000

RADIO- 1. 1204. 104. 14

Software number : 1.29.206.11

Kernel version: 2.6.39.4 – g6b459dcroot@ABM023 # 1 SMP PREEMPT

Baseband version: 1.1204.105.14

Build number: 1.29.206.11 CL63214 release - keys

I Unlocked etc. to change UK -O2 boot animation using Root Explorer with Superuser permissions. I located and replaced the bootanimation.zip in /system/customize/resource, the new animation did not boot, instead the standard android bootanimation took over, although the new bootanimation.zip is still in the appropriate location. I was still happy with that. All functions in the phone were working fine.

Few weeks later I replaced stock kernel and recovery and relocked the phone in the hope of receiving OTA updates although it may have been from O2 since their CID is attached to the IMEI. I did this mostly with fastboot commands such as fastboot oem lock, since then my phone restarts if I attempt to play any type of audio or navigation. I Unlocked, rooted etc. again and tried several different stock kernels, however I was not able to fastboot a boot.img. I even restored it from the backup I made soon after changing bootanimation and when the phone was working fine, that did not even pickup to rectify the audio problem.

Current CID does not allow me to flash a standard HTC RUU, I transferred a zip version, namely: ‘One_X_1.29.401.12_odexed’ to the SD card, cleared all necessary data, partitions and caches and updated the zip using clockword, it went fine, rebooted with HTC One bootanimation, but did not solve the audio problem. I have now again gone back to my first backup.

I have now, ‘from hotfile’ downloaded the appropriate RUU: ‘RUU_ENDEAVOR_U_ICS_40_O2_UK_1.26.206.2_Radio_1.1204.90.13_release_251230_signed.exe’ that corresponds with my CID and was ready to run it and see if it accepts when I came across your information for where to look for the CID, this interested me, previous to that I pulled ‘mmcblk0p4’ and had been looking for it in there.

BACK to CID Question, sorry about the long explanation;

Been looking to change CID; from your information [thanks] I was able to located the CID.

What I have done so far:

Using Root Explorer I copied ‘mmcblk0’ to the SD card, transferred it to the desktop straight away made copy of it, using Hex Editor (HxD) I overwritten CID from: ‘O2___001’ to ‘HTC___001’ at Offset: 00A00000 and saved it as ‘mmcblk0NEW’ I re-checked the size with the copy, both show as:

In properties/General:

Size:	3.99 GB (4,294,967,295 bytes)

Size on disk	4.00 GB (4,294,967,296 bytes)

I thought, if I were be able to successfully change the CID and install stock RUU, ideally: ‘RUU_ENDEAVOR_U_ICS_40_HTC_Europe_1.29.401.7_Radio_1.1204.104.14_release_259281_signed’ then ‘HTC__001’ CID is more likely to receive future OTA updates as opposed to the SuperCID: ‘11111111’.

TWO QUESTIONS:

1.	Other than at Offset 00A00000, there is mention of CID at other places too in ‘mmcblk0’ such as at Offsets:

xml default xml:	082DC020 - 082DC030

O2-UK=999	:	09656000 – 09656010

CID Repeat	:	09656050 – 09656060

CID maincid	:	096565C0 – 096565E0

Cewkey	:	09656670

Beginning descriptions are not worded as in ‘mmcblk0’ I just gave an indication.

Will changing the CID at Offset: 00A00000 alone allow installation of stock RUU’s or do other need to be changed too?

2.	As I mentioned I have edited the CID and re-named the file.

Will the CID change if I was to place the edited file (that I named ‘mmcblk0NEW’) to the SD card and use Root Explorer to place it in the same folder as ‘mmcblk0’, then move the original ‘mmcblk0’ and re-name ‘mmcblk0NEW’ to just ‘mmcblk0’ or do I need to push it using fastboot?

I am saying this because even with S-ON I was able to delete the original bootanimation.zip using Root Explorer with Superuser permissions and change Rom after placing it to the SD card using clockwork.

Thank you for your time.
