Hey, If you are S-ON you have to do one step more. Go as to my sequence.
I assume you have already downloaded fastboot, drivers and android in your pc. And your phone is bootloader unlocked via HTC dev method and rooted, CWM installed. So ..
You need these : SuperWipe (To wipe data) , A Custom ROM ( I suggest Mwakious Demcritous 3D v7.0) / Put these to your sdcard root and Get a copy of these on your PC hard drive too.
1. First go to your recovery menu ( Here its CWM) and select Install from zip file.
2. Select the SuperWipe.zip and click OK, this wipes all your data.
3. Now again select install update from Zip file on recovery . Select the Custom ROM zip file from the sdcard and click install.
4. Then youll see its getting installed. Once its done select turn off your Phone from recovery menu.
5. BOOT IN TO BOOTLOADER Menu now. (Holding vol down + power) , DO NOT TURN ON YOUR PHONE OR YOU'LL get STUCKED in BOOT LOOP
6. Connect the phone to the PC, then bootloader menu will say --> Connected via USB
8. Now unzip the same ROM file youve got in your Hard Drive. Once done find a file called "boot.img" inside that unzipped folder.
9. Now open up a cmd, go to you android tools location (eg: C:/>Program Files/Android)
10. Type > fastboot devices ( If this shows some result which makes any sense proceed to step 11)
11. Now type the below command on the CMD.
"fastboot flash boot C:\<Location you've extracted the zip>\Mwakious3DRom.v.7.0\boot.img"
12.If the result says DONE, you are good to go.
13. Turn off the phone and On it now
14. You should be logged in without a problem, guaranteed !!! Otherwise let me know
Thanks

Thank You Very Much And Where Can I Find This ROM?
-------------------------
BOOTLOADER
-------------------------
First, you must unlock the bootloader so that we can modify the kernel and use custom roms. To do this, you must go to The HTC Developer Website and follow the instructions.
WARNING: This usually voids your warranty.
Pre-requisite for rooting:
Setup an Android Development Environment by clicking here.
-------------------------
ROOTING
-------------------------
In order to install custom roms, you must first root.
Follow these steps to root:
1.) Download Amon Ra here.
2.) Next, load your phone into bootloader (as you did in unlocking it)
3.) Click "Fastboot" using the power button.
4.) Plug your phone into your computer.
5.) Open a command prompt (Start > CMD) or (Start > Run > CMD)
6.) Run the command:
Code:
fastboot flash recovery (file directory)\amonra.img
-Of course you'll want to replace "(file directory)\amonra.img" with the location and file name of the amon ra you just downloaded.
7.) Now, get out of fastboot by clicking "Bootloader" or "Restart Bootloader".
8.) Select "Recovery".
9.) Now, your Rezound will load up the Amon Ra software we've just installed. Go down to "Developer menu" and press power. Then, select "Install su & superuser" and press power. Once it has finished, you've rooted.
Prerequisite to flashing custom rom:
You must download the files needed:
For S-ON Gingerbread Devices: Download The Rom, the PH98IMG.zip, AND the GB Firmware Patch
For S-OFF Gingerbread Devices: All of the above except the PH98IMG.zip file.
For S-ON/S-OFF ICS Devices: Same rule as above applies, except you don't have to download the GB Firmware Patch.
After downloading these files, reboot into Recovery.
-------------------------
FLASHING CUSTOM ROM
-------------------------
The next step is the one you want to do now. Flash the custom rom you want running on your device. Do this by following the steps below:
First, we must clear the cache. In Recovery, go to "Wipe", and choose "Wipe ALL data/factory reset", "wipe /cache" and "wipe Dalvik-cache". You will be prompted to delete each set of files.
Now, go back to the main menu of Amon Ra (Press return until you're at the main menu)
Choose "Install files from zip" and choose "SD card".
Now, choose the ROM you want to install, and install it. Also, if you're on Gingerbread, install the GB Firmware Patch the same way you installed the rom just now.
When it's done, reboot into bootloader. When you do this, the phone will automatically install the PH98IMG.zip file (the kernel). From here, you should be home free! Load up your phone normally and set up your accounts as you would out-of-box.
ISSUES:
If you don't install the GB Firmware Patch and were running Gingerbread, you could have problems such as the device restarting when it attempts to connect to Google or other services involving the mobile network.
If you have any questions or issues, please post a reply and I will attempt to help you to the best of my ability!

Hey everyone, I'm brand new to this, and I was told before I start getting into ROMS that I need to run this software:
http://forum.xda-developers.com/showthread.php?t=1182871
So I followed each and every step, and my phone rebooted and it said "Unlocked" like it was supposed to. BUT, when it booted into the OS, it booted into the stock OS as if I had just bought it off the shelf. Additionally, I am seeing a little exclamation point and android character when I go to the Android Recovery option under fastboot (also installed via linked software)
What happened!?
Congratulations, you have just successfully unlocked the bootloader. Obviously you had higher hopes and were expecting bells and whistles, sorry to disappoint but that's it for this step. Next, flash a custom recovery via fastboot (I recommend the RomRacer's version of CWM), and then use that recovery to flash whatever ROM you choose. Instructions for all these steps are available in other threads. Good luck!

I thought when the phone rebooted after unlocking bootloader, it would boot back into the system I had before unlocking it? I flashed the "Tenfar recovery" that was in the automated script. However, when I flashboot into "Android Recovery," this is when I get to the exclamation point/ android character. Is this normal?
EDIT: I just reran the script to install recovery, and it seems to have worked the second time. I ran a backup and saved it on my external SD card, but is this backup of MY system, or of whatever its now booting into after being unlocked?
Ok guys, apparently I've somehow managed to screw this up. I swear I am following instructions completely!
I decided to try MIUI first, and so I made the backup, wiped all the data/cache/etc, and flashed the ROM. Upon reboot I discovered I couldnt get past the Dual Core screen. So, I rebooted into recovery and flash my backup, and have now found out that I cant get past the "Rethink Possible" screen.
Since at that point you haven't flashed anything else yet, the backup you made couldn't be anything else but your "normal" system.
No idea what (if anything) might've gone wrong, but here's something that you maybe didn't know - after flashing a new ROM, the following boot will always take MUCH longer than usual. After that the phone should boot at "normal" speed again. So have patience and give it time.
Also, not sure how come you're stuck at "rethink" screen. As far as I know that's the very end of the boot process, it is shown just before the launcher starts. Still, give it more time. If nothing happens after, say, 5 mins, try booting into recovery and wipe data and cache, then try booting normally again.
I think I may have found the problem. When I go to restore, it runs for a while, and then says "Error formatting /data"
What should I do?
Alright, im at a loss here. I've done everything I can think of. I've tried every restore setting possible, I've wiped everything MANY times, I've flashed a few diff ROMS to try to get ANYTHING to work.
I am utterly confused about why none of this is working. I've read so much info on the forums that my head is just swimming. I never thought this would be that hard.
At this point I'd just like to get ANYTHING working so that I have a usable phone tomorrow.
sounds like you're having lots of fun :laugh: try not to worry... we've all been there to varying degrees
If this was me I wouldn't go down the 'fastboot' method but just stick to accessing android recovery by the 'power off/on, hold volume down when powering on, and then selecting android recovery'
After this you should be into the phone's recovery mode with the menu in front of you? scroll down to 'wipe data/factory reset' and select (by pressing the power button) after this select 'wipe cache partition' and repeat the process.
Then go to 'install zip from sd card' and select this... if you have installed the ROM's correctly you should have a list at the bottom of the 'sd card' list? Select the rom you want and install by pressing power button ect.
Once this has been installed you then need to 'go back' to the main recovery page and then select 'reboot system'
Let us know if this helps... and good luck!
i would add wipe all (data & cache) again after installing!
I would try this:
Power down your phone, go to fastboot mode (Power + Vol-, then find Fastboot with Vol- and confirm with Vol+), connect to computer, then on the computer run these commands:
Code:
moto-fastboot erase -w
moto-fastboot reboot-bootloader
Then in the same menu as before, select Android recovery (and confirm with Vol+). When in recovery, try doing restore again.
If that doesn't work either, here's an alternative method to wipe /data from recovery using adb.
When in recovery, connect the phone to the computer and run this:
Code:
adb shell
That should place you in the phone's shell. Now in recovery go to Mounts and storage > Mount /data.
Then in the phone shell (on the computer) run this:
Code:
mount | grep /data
It should print something like:
Code:
[color=red]/dev/block/mmcblk0p[B]XX[/B][/color] on /data type ext3 (rw,nodev,noatime,nodiratime,errors=continue,data=ordered)
Note the first value printed. For me it's /dev/block/mmcblk0p16 but I'm not sure if that goes for all Atrixes out there, so better safe than sorry.
Now go back to recovery and select Mounts and storage > Unmount /data.
Now back to the computer - run this:
Code:
dd if=/dev/zero of=/dev/block/mmcblk0p[B]XX[/B]
Where XX is obviously what you got from the previous command.
When it's done (you get your prompt back), type exit and go back to recovery on the phone. Now you can try restoring your backup or flashing a ROM or whatever.
Solved

This is EXACTLY the process I had been using. I just tried this again with MIUI, and again I got the screen that said MIUI was successfully installed from the sdcard. I rebooted, and now I've been stuck at the "Dual Core" unlocked screen.

As you don't know about fastboot I would suggest you to download automatic bootloader unlock from here http://forum.xda-developers.com/showthread.php?t=1182871, unzip it, you will find img file named " recovery-clockwork-4.0.1.4" replace it with romracer recovery you downloaded and rename the romracer recovery as " recovery-clockwork-4.0.1.4". Just to be safe even replace the "recovery-en-goapk-0630-1029" with rom racer recovery and rename it as "recovery-en-goapk-0630-1029". Open main and select option 6 and follow the on screen instructions.

Okay, so I did this and then went in and reflashed MIUI and it worked! Of course, now that I think about it, I should've created a new backup or something, but I guess its too late now.
On a side note, where can I find that google apps package?

You will find the link for gapps from thread you downloaded the rom, I would suggest youto flash CWM touch recovery as it will make future flashing easy. Download it from here http://forum.xda-developers.com/showthread.php?t=1475444, and flash it the way you flashed the rom. Try out neutrino Rom if you are looking for fast and battery efficient rom
There are fruitcakes if you want to go back to stock rom.

So I am currently on hboot 1.50 and today i attempted to install the new viper rom. It's based off of the new ics release.
I kpet getting bot loops with it so I wiped and then attempted to restore back to my cm9 devil toast.
Now i'm stuck in a boot loop. I was wondering if you guys knew how to get back into a rom.
I'm currenlty not at my home computer so I can't connect it to the computer and boot into recovery via the computer.

You are the fourth person today for whom I am writing the same solution but try it from someone else's computer if you want cause without it you will still be stuck..
Try the following steps,
1. go to recovery > wipe & factory reset, wipe cache, wipe dalvik, go to mounts and storage, wipe system, data, cache, sd card... everything u can find there... wipe all..
2. in recovery DO NOT REBOOT, turn off phone
3. go to android development of evo 3d gsm, find a rom, for example mikrunny 1.06, open the archive extract the boot.img from the kernel folder.
4. assuming u have android sdk installed on ur computer, make a new folder and from the android sdk tools copy adb.exe, fastboot.exe, adbwinapi.dll (exact same files u used to unlock bootloader). also in this folder put that boot.img you extracted from the rom
5. put that folder in C:\
6. get back to phone , still DO NOT BOOT UP YET, and power up phone in bootloader mode (vol down & power) and go to fastboot
7. connect phone to pc in fastboot usb mode
8. open command prompt, type cd c:\"folder" ("folder" = folder u created with the sdk tools)
9. type in cmd: fastboot flash boot boot.img
10. after it's completed, go to recovery, still do not boot up phone
11. in recovery go to mounts and storage, usb storage and now copy the whole rom and nothing but the rom on the sd card
12. install zip from sdcard, select rom and let it install, it should boot up automatically
steps were given by SeptimiuB, I am just replying to your query because I've gone through the same mess and recovered as well.
Just unlock your bootloader and install a recovery before trying the above steps.
Cheers.

Hi,
I have the ATT One X+ with ViperXL+ installed on it and TWRP as my recovery. I rooted it using hasoon's toolkit and followed his stpes. Now I would like to switch to Elegancia, just to try it out. Would I do this by simply loading it onto my phone, going into TWRP, and selecting flash ROM? Or is there a longer set of steps to follow? Do I have to flash another boot.img? Additionally, do I have to reinstall all my apps and redownload all my music?
Thank you for answering
Hi Killfire,
Switching between ROM is not that hard, but as for your apps and data you will need a third application like Titanium Backup or My Backup to transfer all your personal stuff from one to another. If you don't have that much application and personal data to restore it's not hard to do it manually.
Yes you have to flash the correspondent boot.img to the ROM you selected. They practically all have something different, so do flash the one recommended in the changelog.
As for your music, that should be safe if you don't wipe your SD card, if your music was transfer from your computer as well.
If you want to change from ROM A to ROM B
Put the ROM you wanna try to your virtual SD card
Reboot in Recovery
Do a full backup of your actual (excluding cache and recovery)
!! The following instruction are with TWRP Recovery installed !!
Select Wipe menu, then select Factory reset (swipe), select System (swipe)
Go back to the Install menu and select it.
Locate your ROM.zip and select it.
Swipe to confirm.
Probably Aroma installer will start, simply follow the on-screen instructions and complete the installation.
Complete installation
Reboot in bootloader mode.
Make sure the FASTBOOT USB is highlighted.
Use the provided tool to flash the appropriate kernel. Or simply do it like this throught SDK/ADB
At the prompt type >fastboot flash boot insert_your_boot_image_name_here.img (Enter)
If Success is achieved, type again at the prompt >fastboot erase cache (Enter)
You now have a customized boot.img installed.
Unplug your USB cable and hit Power button one time.
Select Reboot with your Volume rocker.
Hit Power button one time.
Your phone should reboot.
