* How To Root, Update Firmware, & Flash A Custom ROM
--> Unlock your device
Step1. download and use this program to unlock your bootloader http://forum.xda-developers.com/show....php?t=1604677
Step2. SuperCID your phone so you can S-OFF and so you can also write the T-MOB010 CID if you are on a different carrier and want to run this ROM. You will need to be CID T-MOB010 if you want to run the firmware.zip Follow this to SuperCID http://forum.xda-developers.com/show...1#post26516911
Step3. After you have sucessfully unlocked your bootloader and SuperCID you can either S-OFF your phone or Not, it is up to you. I would recommend you achieve S-OFF so you can flash radios, kernels, and boot.img's. Follow this to achieve S-OFF http://forum.xda-developers.com/show....php?t=2155135
If everything went well you should be able to reboot into bootloader using the All In One Tool and in the top left your bootloader should say Unlocked, S-OFF, CID-1111111
--> Writing T-MOB010 CID
If you did everything right then your all set. Next you will want to run the fastboot command " fastboot oem writecid T-MOB010 " and reboot into bootloader again. Now in the top left it should say CID-T-MOB010. If you have made it this far you are doing great. Now we are going to run the firmware.zip package to ensure everything works without a problem.
--> Flashing the firmware.zip
You must know how to adb fastboot with command promt windows only
Download this :
Now if you are coming from STOCK OEM LOCKED T-MOBILE PHONE that already has Andorid 4.1.1 Jelly Bean on it then you do not need to do this step. You must be CID T-MOB010 to flash this or S-OFF CID 11111111
1. fastboot oem lock
2. fastboot erase cache
3. fastboot oem rebootRUU
4. fastboot flash zip firmware.zip, and you might get an error
5. fastboot flash zip firmware.zip again and it should pass and install a bunch of files should take about 2 minutes.
6. the phone does NOT reboot on its own so #7
7. fastboot reboot or fastboot reboot-bootloader
--> UNLOCKING BOOTLOADER AGAIN
Now we need to unlock the bootloader again so just do step 1 again but you will already have the Unlock_code.bin from the first time you unlocked you phone so no need to get another one from HTC but if for some funny reason it doesn't work you will need to just resubmit for a new one.
--> CUSTOM RECOVERY
After doing all the above steps you will need to install the custom recover. You will need to use TWRP 2.3.3 to insure no problems. Here is the link to download it http://techerrata.com/file/twrp2/vil....3.0-ville.img
after you download it go to the DIR where you have the HTC One S All-In-One Toolkit v3.5 extracted. example: C:\Users\yourusername\Downloads\One_S_All-In-One_Kit_v3.5\One_S_All-In-One_Kit_v3.5\Data\Recoveries and in the Recoveries folder rename the downloaded twrp2.3.3.img to TWRPS4.img and replace the one that is in the folder and then proceed to install the recovery.
Your current phone status
Bootloader = Unlocked
HBOOT = 2.15
CID = T-MOB010
Custom Recovery = TWRP 2.3.3
You are now ready to flash any Jelly beam ROM.
