First thanks to:

1. mtothearkus
2.petarpLab..
3.jcase for TacoRoot..
4. amidabuddha


I AM NOT RESPONSIBLE FOR ANYTHING THAT MAY HAPPEN TO YOUR DEVICE..

This was tested on latest OTA ASIA 2.15.xx with latest Hboot 2.00.0002.
Latest 2.15 cannot be rooted with zegRush so did some research..

Things Needed:

1.tacoroot
2.misc_version (download attachments below)
3.OLDEST RUU for your "REGION/ BRAND".. i repeat, specific region to avoid customer ID error.
4. adb (you know how it works)
5. phone in USB debugging mode.


STEPS:
1. download tacoroot and misc and put all files in your desired directory.
2. Run terminal and change location to where you files are.
3. now type:

Code:
adb push tacoroot.bin /data/local/tmp/tacoroot
adb push misc_version /data/local/tmp/
4.After pushing all the files, run tacoroot by typing:

Code:
adb shell 
chmod 777 /data/local/tmp/*
/data/local/tmp/tacoroot --setup
5. After this commands your phone "REBOOT" the phone to recovery. Now press vol up then power then REBOOT to boot the phone normally. Wait till it boots completely and then type:

Code:
adb shell
/data/local/tmp/tacoroot --root
6.This command will gets you out of adb shell.. so we need to get back to adb shell and you will see "#" sign..meaning you are temp rooted and we can then proceed to changing MISC_VERSION:

Code:
adb shell
cd /data/local/tmp
./misc_version -s 1.27.405.6
7. After its done you can now flash your "REGION/ BRAND specific RUU".
8. After your done with RUU. Proceed to http://revolutionary.io..

Happy Flashing
Ok, so instead of creating a new post i have decided to post it here since it is already been discussed.

I was happy with rooted phone and endymion Rom and was happy until my phone started heating up and restarted on its own as if it had a mind of its own, I called HTC and they advised to send it for repair, i had to unroot the phone and sent for repair. Got the phone back with updated version and i need help rooting the phone.

when i boot the phone in fast boot this is what i get:

****LOCKED****
SAGA PVT SHIP S-ON RL
HBOOT-2.00.0002
RADIO-3822.10.08.04_M
eMMC-BOOT
Aug 22 2011, 15:22:13

Android Version 2.3.5
HTC Sense Verison 3.0
Software Number: 2.14.841.4
Baseband Version: 2.14.841.4 CL 184593 Release-Keys

Now i need to Root the phone again so i can be another happy user of endymion.

I am looking at this guide and needed help.


The oldest RUU i can find for my provider is RUU_Saga_Telstra_WWE_1.36.841.3_Radio_20.28d.30.08 05U_3805.04.02.01_M_release_184558_signed.exe

I was reading the guide and this is where i am confused.

[I]6.This command will gets you out of adb shell.. so we need to get back to adb shell and you will see "#" sign..meaning you are temp rooted and we can then proceed to changing MISC_VERSION:

Code:
adb shell
cd /data/local/tmp
./misc_version -s 1.27.405.6 [I].

./misc_version -s 1.27.405.6 do i change this to 1.36.841.3 or leave it as it is?

Any help will be greatly appreciated.

Thanks.

Leave it as it is. You have the 2.14 version. Applying misc version will let your RUU think that your current rom is 1.27.. so you can proceed with update of RUU.. the steps are clear.. there where no steps indicated that you have to change the misc version provided.

You don't need to downgrade hboot to install endy.

- Create goldcard (with other device if necessary) and install whatever ruu you can.
- Update ota to the latest version available
- Setup device to your preferences
- get your device's bootloader ***UNLOCKED*** trough htcdev
- install (flash via fastboot) REVOLUTION, or 4EXT recovery img
- perform nand backup via recovery
- install your favorite rom (detailed instructions here)
- enjoy!

ps: if you didn't understood latest step in directions how to install rom in linked post, you extract boot.img file FROM ZIP OF ROM YOU ARE INSTALLING.

Similar stuff goes for returning to stock. It's not enough simply to restore trough recovery. You must flash boot_signed.img after you performed restore process.

pss: if you think there are some excess steps in my directions feel free to skip, but only if you are 100% sure you know what you're doing...

You can also root device installing SU via recovery

And one more thing... While playing with ruus, if anything goes wrong there are pretty decent chances that you will be forced to pull out battery from your device. Make your best effort to avoid this, and if you really must, than wait at least 30sec before putting battery back in your phone.

Good luck!
