US AT&T HTC Titan I (Eternity) HSPL Success (Plan B!)

HTC Titan I (Eternity) - Plan B!

1.	These instructions are for the United States AT&T variant HTC Titan I (Eternity) device only. They are not for the HTC Titan II (Radiant) or the rumored HTC Titan III (Zenith) with Windows Phone 8.

2.	You must use the Gold Card Method!!!

3.	When I say, ETERIMG or ETERDIAG and copy these files to your gold card, you will not add quote or bracket or dot symbols or the characters “.nbh”. The file name is either 7 or 8 characters long; that’s it! The web location of the ROMs you will be using is at File Factory - http://www.filefactory.com/f/db553db625fe2273/ . I had success with both the following ROMs; they are:

a.	IMG_Eternity_HTC_Europe_1.09.401.02_Radio_16.23.02.09_A… (Radio 16)

b.	IMG_Eternity_Cingular_US_1.10.502.04_Radio_16.23.02.26_A… (Radio 16)

4.	Hardware

a.	My success came with using a PNY 4GB USB flash (thumb) drive that comes in two to a set ( one red and the other dark blue) at Wal-Mart and I paid $11.88 (as of this typing). My Y-cable was bought from Amazon.com - http://www.amazon.com/StarTech-com-...d=1356750625&sr=1-3&keywords=usb+a+to+a+cable. You will also need a USB Gender Change adapter also at Amazon - http://www.amazon.com/SANOXY-USB-Gender-Changer-Female/dp/B000BSN4UY/ref=pd_bxgy_e_img_y .

b.	My Sun-Pak 72-in-1 is a multi-card reader and like the instructions located at http://xdaforums.com/showthread.php?t=1744253 . I can confirm you’re wasting your time trying to use this with your Y-cable.

c.	I did buy new a Nokia 1GB microSD which as all of you know up to 4GB is generally non-SDHC. It came with a SD adapter that I never used and came with a USB adapter which is flimsy at best. For durability go with the PNY thumb drive but no greater than 4GBs.

5.	Referring back to instructions at # 3, I had success with both ROMs but not before my patience was severely tested. I own two Titan I (Eternity) devices. Initially, I had no success with the Eternity European ROM 1.09, the damn ROM simply would not flash. My model numbers were “x310a”; I assume that means they’re American and “x310e” means they’re European. My wife’s Titan was flashed as per the instructions we all have read a bazillion times; what follows is my device after it originally was HSPL and using it as a guide to walk her device through; my results were inverted; her device is HSPL and my device was no longer HSPL which up until that moment I thought was impossible to revert; I was wrong. What happened next is a lesson in what many of us have shared – “SPL2.5.160015.3 (137079) hell. My device would not downgrade or upgrade; it would not budge and in the end, it didn’t have to. What follows are those steps.

6.	Creating your Gold Card – The tool maker can be found at - http://me.klaus-widraw.de/files/wpg/goldcardtool.exe. The Gold Card image is at - http://me.klaus-widraw.de/files/wpg/goldcard.img. Whether you use microSD or USB thumb drive, you are to use your computer to “quick format” them. This is not a typo – Quick Format!!! You will set “FAT32” and the cluster size to 4096; these too are not a typo. Once done, you will not have to do this again, the files will simply be renamed, copied and deleted from this point forward.

7.	Whatever case, shell, indestructible material you have surrounding your device is to be removed. Unless you’re blessed with tiny fingers, you will need your cell’s back cover to enjoy the wonderful adventure of finger gymnastics with your device.

a.	“Entering USB Host Mode” is toggled by pressing down the volume down rocker and the camera button at the exact same time; you will do so prior to holding down the power button but only long enough to screen be turned on and white in color and then you will let go of the power button while you continue to press down the volume down rocker and camera button until you see these magic four little words.

b.	To enter the Bootloader Mode is to simply toggle both volume up and volume down at the same time; they are independent of each other and can be pressed at the same time. You will do this prior to pressing down the power button and will continue to hold all three of these buttons down until once again you see the white screen and then you will continue to hold down the volume rocker keys but let go of the power button.

8.	Please make sure your battery is sufficiently charge; I know these folks say 50% but it’s a good idea that should you find your device sitting at 10% let me just preface, you were warned! When these folks over and over and over say “read”; do it!

9.	Step 1 of 3 - Download your ROM, place it in a folder on your PC and unzip the devil. A quick tutorial on your Y-USB cable – the whole purpose of this method is to avoid whatever headaches the carriers and Microsoft were kind enough to not tell you about the adventurist in all of us. If you have a red/black Y-USB cable; red is your power source, it will be on the same side right alongside of your micro-USB cord. The opposite end is where you will add a USB Gender Change Adapter so either your microSD/USB adapter or your thumb drive will snuggle up nicely with your cable.

a.	Rename the file to ETERIMG and proceed to copy the file to your “gold card.” Reset your device to “Entering USB Host Mode…” Do not put the micro-USB adapter from your Y-USB cord until this is done first. Make nice with your device, one Hail Mary and one stiff drink and plug your cord into the device. What you will be looking for are the words “ETERIMG.NBH” top-center in blue. Below it you will see in the following order Radio, Bootloader, A1026, RCUST, TOUCH, and OS. As soon as you see “OK” next to “Radio” your device will automatically restart and return to USB Host Mode where you are to expect “OK” to the right of Radio, Bootloader, A1026, RCUST in blue font and in yellow font the following: >*>*>* (greater than symbol and asterisk symbol; my device had 7 and ½ rows of them. The next words will be in white with blue highlight “Update Complete, UPDATE SUCCESSFUL”. Pull your battery, wait 15 seconds, put the battery back in and fire it up. As the initial OS installation proceeds you will be looking for “HTC Titan x310e” before you begin installing other applications. If you see “HTC Titan P139100”, the installation was a failure and you have returned to the 7.5 build 7720 glory days of yester year. If “x310e” is out there; you’re good to go. I don’t care if your SPL does not say 1.09 or 1.10 and you’re staring at that evil SPL 2.5; you’re not dead.

b.	This next step does not apply to those who their phone reads HTC Titan x310e and SPL2.5; you’re not dead though you might think you are. This step does not apply to those of you who successfully have in your settings and your bootloader SPL1.09 and SPL1.10.

c.	If your device does not read HTC Titan x310e – welcome to step 2! – Delete ETERIMG from your Gold card; do not change the name of the file; we return to the folder where your ROM was unzipped and change it there to ETERDIAG and then recopy it to the Gold Card and do this all over again.

d.	If after doing it all over again and you’re still staring at HTC Titan P139100; Plan B, download the other ROM; if you attempted and failed with the European, download the Cingular; you struck out with the Cingular, download the European; which is exactly what I did and I struck out with the file named as ETERIMG but successfully flashed it with ETERDIAG as its filename.

e.	If none of the above worked for you, keep tinkering and please let us know what you did different. I realize much of this may be a repeat of what many already know but I wanted to write this guide with common sense English.

10.	Step 2 of 3: Download DFT__HSPL_WP7SG1.rar from http://htcfanboys.com/download/cotulla/?action=view&file=10777 and place it within a folder of its own.

a.	Extract the contents of this compressed file. There will be two folders “OMEGA” and “TITAN”. Open the Titan folder and within it there are two folders - “SPL205” and “DFT HSPL”. Open SPL205. I do not remember if these files were zipped or not; either way what we’re looking for is what looks like all the goodies you would need to flash via Bootloader a RUU method. It is the 24.528 mb .NHB file we’re interested in. Rename the file ETERDIAG and copy it to your Gold Card.

b.	It is really important with this next step to be patient. If upon restart of your device and it re-enters USB Host Mode and it sits there and sits there as if it’s doing nothing; wait! At least a good 15 minutes! When I had given my device up for dead; it came to life and flashed the .NBH file. It said, Radio – OK, Bootloader – OK, Update Successful, UPDATE COMPLETED. It has to read this; no matter what! The SPL will lead you believe nothing happened; it will still read 2.5.160015.3. For those of you who proceed to step 2 from a SPL of 1.09 and 1.10 know the SPL will return to 2.5.160015.3 upon completion of this step.

11.	Step 3 of 3 - Restart the device in Bootloader mode, Open Zune on your computer, and plug your device to your computer; it must read “USB” bottom-center. Open “DFT HSPL” and right-click “DFT_HSPL_WP7SG1_INSTALL” and run as administrator and follow the prompts within this application. Upon completion the device will automatically restart and will return to the Bootloader screen where SPL2.5.160015.3 becomes HSPL2.5.160015.3 and “CotullaH” replaces “Touch”.

12.	Proceed immediately to flashing your custom ROM and if necessary the radio with that ROM.

13.	“ETERDIAG” interacts with the device a bit different than strictly “ETERIMG”. Like many of you, I thought if I could not downgrade the SPL and I was dead in the water. You must have “x310e”. “P139100” won’t work, no matter what you do. “x310e” implies you are “debranded”.

Finally, I’m not going to sit here and tell all of you this will work on each and all your Titan I devices; my wife’s setup was by the book; my device, was in essence Plan B. I will tell all of you the same thing the folks who do this work every day, there are risks involved here, you can “brick” your device. Off the record, I never lost the SPL. I must admit I got sick of pulling the battery out and restarting the phone a bazillion times. Y’all have a good evening; wherever you may be; take care! You're welcome to PM me but please know I'm not a developer or programmer; I'm a retired weather forecaster and a full-time college student majoring in math education; that's calculus assuming anybody in their right mind calls it math. Please be patient and good luck and please let us know what worked and what did not work; Happy Holidays and Happy New Year 2013!
