Hey Guys So i was able to successfully unload my bootloader and root my phone via 2.20 root temp method. Now i've run into a wall where I seem to be following the directions, but can't seem to get it to work.
So after my phone was unlocked etc after the whole token thingy... (Sorry this is my first time since 3-4 years ago that i have rooted.. Last phone was a Droid X so excuse my ignorance).... Anyhow so my phone got reset and all and booted back and everything was fine and working.. Now according to the thread in order to flash a ROM of my choice i need to install some sort of Recovery tool. The instructions say to install TWRP-2.3.1.0-evita.img. I have put the .img on the same folder c:android that i have created where i have the adb, fastboot files. I open up a command prompt window and run the command "fastboot flash recovery twrp-2.3.1.0-evita.img and it says "waiting for device" and get's stuck there and nothing happens.
According to the post it is supposed to install it and restart my phone automatically, however nothing happens. I am afraid if i reboot my phone and try again that my temp root will go away and will have to redo-everything all over again. Additionally I have tried the market place method where you download "Goomanager" and install the twrp img via menu>openrecoveryscript and choose to download, however i get an error when attempting to download. Can someone point me in the right direction. And will i lose temp root if i reboot my phone?
"Hey guys i just notice i did not run the "adb fastboot" command to tell my phone to reboot first prioer to trying to flash the twrip image. Sorry"

I just downloaded superuser and busybox. Also i downloaded root checker and when i click on check root it says my phone is NOT PROPERLY ROOTER. Can this be because of how HTC ONE X gets temp rooted and this app doesn't work properly? How can i check for sure if i'm rooted? I mean i can get into TWRP recovery and everything with no issues. Thanks.
I believe that because you did not download superuser before reboot. I think you lost root. Might want to try again.

So after i Ran the run.bat and did the entire cid and then token thingy from HTC site and unlocked my bootloader the phone rebooted on it's own.
I believe i need to install superuser via recovery or flash a rom first then install not sure.. the way the dev wrote this phrase is confusing to me.. Check it out...
10. After unlocking the bootloader, you can flash a custom recovery partition via fastboot, boot into recovery mode, and use a recovery ADB shell or install from an update.zip to install Superuser and su (I do not provide support for custom recoveries, but this is a straightforward process that other people can help with).
I mean every step form 1-9 all went successfully. Can you provide me with some tips ?
Oh OK. I get it. Give a sec I'll post what you need.

Thanks for helping me out, much appreciated. Also look's like i will need to find the superuser file somewhere online. I believe it needs to be inside a .zip. If i need that can you please provide that info on the instructions. Thank you so much for helping me.

So i did not download the CM recovery as i already had the TWRP recovery installed prior to my post. I put the superuser zip file in my CD Card then i adb reboot recovery within command prompt which brought me into the Team Win Recovery Project V2.3.1.0, I then selected install and choose the superuser zip file you linked me to download, however it fails with errors. Do you know what I am doing wrong?
I think this all has to happen before rebooting after the new root process. So CID, then flash recovery, load and flash superuser, then reboot. I'm not sure how others are getting it to stick. I'm rooted on 1.85 with both my HOX's

Im reading line 10 again and i think i need to install a custom rom first via flashboot then boot into recovery to install the superuser zip file. Read this again and tell me what you think?

After unlocking the bootloader, you can flash a custom recovery partition via fastboot, boot into recovery mode, and use a recovery ADB shell or install from an update.zip to install Superuser and su (I do not provide support for custom recoveries, but this is a straightforward process that other people can help with).
1. After unlocking the bootloader, you can flash a custom "recovery" = twrp partition via fastboot,
2. boot into recovery mode, and use a recovery ADB shell or install from an update.zip to install Superuser and su
I think I'm spot on with my last post.

What would be the ADB shell command to install lets say a file labelled superuser.zip ?
I've never tried nor know if possible to flash a zip in fastboot. To the best of my knowledge it has to be a image file.

Never mind guys,got it working! after the via terminal, i just reflashed on Rom manager. Its ok now, i can get into CWM. Any idea why this would happen in the first place though? its odd.
you have to edit the official OTA zip file and remove it from there I'm working on it
Okay, to make this clear, Im re-making the tutorial from miuiandroid forum, which is a little bit complicated if you are in noob mode.
So, first of all, to have MIUIv4 installed on your DS, you need the hboot 7.0. If you already have hboot 7.0 , follow from step 1, if you dont have hboot 7.0 follow all from step A :
Download this first : http://bigota.d.miui.com/tools/g12_v4_tools_20120724.zip
A. Rename PG88IMG_hboot_7.0.zip to PG88IMG.zip
B. Put it in your sd card root.
C. Reboot to bootloader from device, or use adb command ( adb reboot bootloader). Once you in bootloader, make sure it's not on fastboot, get back to bootloader, and it will detects the PG88IMG by itself, and confirmation for update will be shown, just press the vol up button to flash it.
D. It will reboot somehow. Delete the PG88IMG in your sd card root.
E. continue on step 1
1. Rename PG88IMG_SAGA_ICS_35_S_HTCCN_CHS_3.07.1400.2_Radio_20.72.30.0833U_3831.17.00.310_release_266765_signed.zip to PG88IMG.zip
2. Put it in your sd card root.
3. Reboot to bootloader from device, or use adb command ( adb reboot bootloader). Once you in bootloader, make sure it's not on fastboot, get back to bootloader, and it will detects the PG88IMG by itself, and confirmation for update will be shown, just press the vol up button to flash it. It's easy, but this PG88IMG is big, so it will take like 5 minutes to load.
4. Reboot.
5. wait untill it finish starting up, you may skip the first time setup or complete it.
6. Delete PG88IMG from your sd card.
6. Now it is time to flash recovery image as you dont have recovery yet.
7. reboot device into fastboot usb
8. in the folder adb, there's flash_recovery-clockwork-5.0.2.0-saga.bat , run it as it will flash cmw recovery image in your DS.
- if you have error such as multiple device detected or what so ever, open up adb shell and run adb kill-server .
9. Reboot into recovery, full wipe
10. And flash miuiandroid_saga-2.8.3

To boot in the bootloader you can also power off the phone and then press the volume down and the power button at the same time.
But the fastboot commands later probably won't work if adb doesn't ...
I've got a Sensation (I think its a Phillipenes issue) which was upgraded to ICS 4.0.3.
Basically I've managed to complete HTC Dev Unlock, then a few days later I lost Wi-Fi connection, so have been trying to continue with installing a Custom (or even the original) ROM in an attempt to fix it.
I've now done Junoptobear to get true S-OFF
Got root access
But cant get Clockwork Mod to install in Recovery...
I've installed ROMmanager Premium and used it to install the latest Clockwork Mod - it states its downloaded and completed but when I go to the bootloader and select Recovery it flashes the white HTC screen for a brief second then back to the bootloader.
I've tried to manually download the Clockwork Mod file and install to Recovery but I get the same issue.
Does anyone have any ideas?? Many thanks!
Hi there you can install 4ext recovery you can get the file here in xda or even from the play store. Many of us use 4ext because it has many options and is very easy to use.personally I prefer 4ext. All I did was download from the play store and opened the app follow directions choose version of recovery and it will flash from the application. I was already rooted and soff when I did it but it's very easy to do. I really think you will like 4 ext recovery. You already have s OFF and root so it should not be a problem. Best of luck to you. I hope this helps! As I mentioned most of us use 4 ext recovery and I doubt you will be disappointed. Good luck.

Download the superuser to Sd
Download the latest clocworkmod recovery
Reboot phone into bootloader mode
Open a command prompt, go to folder
Now execute this fastboot command to flash the CWM recovery. Change the filename to the file you have downloaded
fastboot flash recovery recovery-clockwork-6.0.1.0-crespo.img
using the vol down key choose to go to recovery
Install zip from sdcard superuser zip file.
Reboot. You now have rooted JB
