Finally after hours and days of search, reading forums, going through the failures and trying almost everything, I finally succeed and if anyone else has error backing up file, use the universal misc version and not the one stated in op and then when everything goes well, go to fastboot and then to know what your misc_version is, "fastboot getvar all" is the command, by this you'll be sure of your version and then I suggest starting the RUU in fastbboot itself as in my case it did not detect the version in normal or OS mode.

So Happy Finally !!!!!!!!!!!!

Stuck after 6th step plz HELP

shadi22 said:
This method works for software version 2.11 and above and doesn't work for version 2.10 below.. Please use zegRush if this doesn't work for you.


Note: For locked bootloaders only. Do not use Htc dev prior to using this guide.

First thanks to:

1. mtothearkus
2.petarpLab..
3.jcase for TacoRoot..
4. amidabuddha
5.zryvffn (misc_version_universal)


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 ;)

Hey,
First thanks for the post i am a noob and new to these things sorry for my silly question but i really need help, i tried you guide it worked perfectly till the 6th step i saw # symbol
but after that i dint understand what to do i have my specific RUU i placed it in the sd card, i dint knew how to flash it.
after the 6th step the ph was continuously looping and stuck at the htc logo, i tried force restart the only way to switch it off was to remove the battery( i know i am not supposed to that) but that was the only way i could find to start the ph.
after that i went in to recovery but nothing hppnd it just got stuck, so i did a factory reset its working properly now but i am still on s-on and hboot 2.00.0002 , i dint flash the rom so i guess i am still on that
But plz tell me how to continue after this

My phone reboots and gets stuck in a boot loop. Do you know why this is?

Im already rooted and running cyanogen mod. I tried to skip root step but that didnt work.


I also tried to go through the steps even thought the phone was stuck in a boot lopp, but i got error 155 from my RUU (RUU_Saga_Vodafone_UK_1.32.161.1_Radio_20.28b.30.0805U_38.03.02.15_M_release_179398_signed)

What should i do?
any help would be greatly appreciated.

If your already rooted, no need to re root.. just change the misc version and flash RUU...

    This does work, if any one is getting error such as Error Opening Back up file etc, try using misc_version_universal to avoid such errors.

    here is what i did and worked for me.

    followed the steps as outlined.

    The oldest RUU from my provider that i could find RUU_Saga_Telstra_WWE_1.36.841.3_Radio_20.28d.30.08 05U_3805.04.02.01_M_release_184558_signed.exe.

    followed the process completely and then on the part where you change version number this is what i used:

    adb shell
    cd /data/local/tmp
    ./misc_version -s 1.36.841.3 (Same number as my RUU)

    i did try using 1.27.*** but i got an error on RUU 140 Boot loader error. i don't know if it was my mistake somewhere or not but i tried twice and i got the same error but thought of giving a last go by changing version number to what i had in RUU and worked.

    i have attached the universal misc version if anyone wants to use.

    Thanks Guys for all the support.

    Cheers!

    The only guide I've seen for hboot 2.02.0002 is this one:

    Not very nicely formatted, I think, but all the steps you need are there

    1. You dont need the command "rm". Because you already reset to factory. By using rm means you remove existing files in the system..
    2. Yes you can flash RUU because youve change the misc version.. you dont need to get rooted to flash RUU.. you temp root just to push the misc version. When you reboot.. temp root will be gone and yes you can still flash RUU because youve done the essential misc version change.
    3. You making things much more complicated.
    4. Read post. Again..this is VERSION 2.. zegRush has the similar guide..
    5. Never advice anyone to pull battery out when flashing RUU.. you may brick the device.
    6. The zegrush method has been linked on the first page..
    7. Youre post seem irrelevant to this thread.. better post this in zegrush guide..

    He seems to have posted it in both the threads...:confused:

    And i agree, his version sounds very complicated and messy, like machinery held together by glue... I like your instructions better...clear and precise.
