FULL GUIDE:

How to install JellyBean 4.1.1 with Sense 4+ ROMs​

I see many people in all the JellyBean Sense threads asking questions about updating the HBOOT and CID etc.

Many people ask: Is it worth it? Definitely!!! The new HTC JellyBean build is smooth as hell and battery life is much improved.

It took me 3+ hours to get it all working, and finally had the ROM running. So, don't think you're done in a few minutes.

And the most important thing: KNOW WHAT YOU ARE DOING! You need some fastboot/adb knowledge. I am not responsible for any damage!

Things to prepare:

- Have the new ROM on your SD!

- Have the boot.img on your PC or laptop

Step 1: Check your CID

Checking your CID is needed because a limited amount of HTC One X' can be updated to the new HBOOT which is needed for the new build.

Reboot your phone in fastboot mode (power-off + volume down), and connect it to your PC or laptop.

Use the following command: fastboot getvar cid

If the answer is 'cid: None' use this one: fastboot oem readcid

If your CID is one of the these you're good to go on:

IF YOU HAVE NO CID NUMBER LISTED ABOVE, STOP NOW! You have to wait until the developers find a way to get it working on your device or an HTC release.

Step 2: Download the new firmware

The new firmware is needed to update your HBOOT for JellyBean

Download here (credits go to Baadnewz): http://d-h.st/tsm

Copy the firmware.zip to C:\

Step 3: Reboot your phone in HBOOT

Reboot your phone back in fastboot mode (power-off + volume down).

Step 4: Relock your device

ONLY START HERE IF YOU ARE ON A BATTERY LEVEL OF 70% OR HIGHER, JUST TO BE SAFE!

Now you are in fastboot mode, let's relock your device!

First flash a stock boot.img, if you don't you will get in a bootloop.

After this, use the following command to relock your device: fastboot oem lock

To see if it is relocked, check the HBOOT mode, in pink font you will see on top ***RELOCKED***

Reboot your phone.

After locking, just reboot to bootlader and enter command - fastboot oem rebootRUU.

Just boot it and you are relocked now and ready for the next step!

Step 5: Flash the firmware!

Now you have booted your phone, stay on homescreen and use the following command in CMD.exe: adb reboot oem-78

Now your phone is rebooting and a black screen with silver HTC logo appears.

Remember you have firmware.zip copied to your C:\ drive!!!

Use the following command now: fastboot flash zip C:\firmware.zip

The first time you will see that this command will fail, just repeat the command and this time it will succeed!

Now you see in CMD.exe that the firmware.zip is successfully pushed! The black HTC screen stays with a full green bar under it.

Now use the command: adb reboot-bootloader

Stay in the bootloader for now.

Step 6: Download HTC One X All In One Toolkit

Download it from this thread (credits go to hasoon2000): http://xdaforums.com/showthread.php?t=1604439

Step 7: Unlock your device again!

Now you are in the HBOOT mode, you can unlock your device again. I have used the tool you just downloaded.

If you have unlocked your device before you still have your unlock.bin in your inbox from HTCDev.com. Download this again and put it in the folder 'data' in the folder of the All In One Toolkit.

Stay in fastboot with your phone connected to the PC or laptop and open the All In One Toolkit. Choose '5. Unlock Bootloader'.

Now you get a black screen with 2 options: Lock Device and Unlock Device. Choose with your volume button 'Unlock Device' and confirm with the power button. Now you are unlocked again!

Step 8: Flash Recovery

Now you are unlocked again, stay in fastboot mode and use the All In One Tool.

Choose: CWM 5.8.4.0. Now you have installed successfully CWM recovery.

Step 9: Flash boot.img and install the ROM

Flash the boot.img of the JellyBean Sense ROM. When done, go in recovery and flash the ROM.zip.

NOW YOU ARE DONE, AND CAN SUCCESSFULLY BOOT YOUR NEW ROM! A FRESH HTC ONE X EXPERIENCE :D

METHOD 2: For everyone!!!

Credits go to Baadnews and TripNRaVeR, but this method is still BETA! USB Mounting does not work yet...

Step 1: Flash a new JellyBean Sense ROM of your choice

Do a full wipe in recovery.

Flash one of the new JellyBean ROMs via Clockwork Mod Recovery.

Step 2: Flash a custom kernel

Flash this kernel from TripNRaVeR out of his thread: http://xdaforums.com/showthread.php?t=1800603

Step 3: Flash boot.img

Extract the boot.img form the TripNRaVeR kernel and flash this one in fastboot

Step 4: Reboot

Reboot the phone and enjoy your new JellyBean Sense experience. This method is still in BETA, because of some bugs. A few devs are looking to get it all working for everyone!
