Cannot get Hard-SPL on your Treo 750? Want to unlock/unbrand your Treo 750?
Check attached files to make your life easier.
Here is a guide to having a successful flash:
1) Create an ActiveSync connection with your phone.
2) THIS STEP IS ONLY FOR VISTA/WIN7 USERS! Follow the guide at this website first and complete all the instructions!
3) Download CheetahUnlocker to your computer, and extract the program - DO NOT RUN IT YET.
4) Download the attached Treo750UnlockFiles.zip and extract it to your computer. Take CHEEIMG.nbh and athena_unlocker.exe and copy them to your SD card.
5) Open/Run CheetahUnlocker.exe, and agree to the warning message. This will open a box with 3 options (2 are greyed out).
Option1:
Click "Flash SPL"
Click Next
Click the checkbox, then click Next
Click the checkbox (again), then click Next (again)
Click the "Update" button, then click Next
At this point CheetahUnlocker will send files to your phone to bypass the protection and flash your phone (called SSPL) and start your phone in bootloader mode. You may have to agree (on your phone) to these files being sent! Since we have placed the CHEEIMG.nbh file on your SD card CheetahUnlocker may respond with an error, ignore this error and click OK, it will go back to its original screen - DO NOT CLICK THE SECOND OPTION YET.
Your phone will find the CHEEIMG.nbh file on your SD card when entering bootloader mode and confirm that you would like to flash the file. Press the "Power/End Call" button to flash this file now, it should go rather quickly and say "Update Success" if all goes well.
After it is finished, pin reset your device using your stylus and the small button near the SD card slot. Your phone will boot up as normal, let it finish entering the OS and reconnect to ActiveSync.
Optional: Enter bootloader to confirm the flash by holding down the "Media" button (round button on left side) and using your stylus on the pin reset button (near the SD card slot) simultaneously. If all went well you should see SPL-1.4.0.OliNex.
Option 2:
Click "Unlock Radio"
Click the checkbox, then click Next
Click the "Update" button, then click Next
The program will flash an unlocked version of the radio to your phone. After it is finished it will boot normally, wait until it is done and has reconnected to ActiveSync. Around this time the program will prompt you with a box telling you it has to send files to your phone to unlock it, this will fail with an error. Click continue and the program will go back to its original screen. On your phone, locate the athena_unlocker.exe file on your SD card using File Explorer/Total Commander/Resco Explorer and RUN it. The program has 2 options, check both of these, then click "Unlock". This will unlock your phone, but we aren't done yet!
Option 3:
Press and hold "Shift" and "2" on your keyboard and click the title bar of CheetahUnlocker. This will unlock all 3 options. Click the 3rd option "Flash Normal Radio".
Click Next
Click the checkbox, then click Next
Click the checkbox (again), then click Next (again)
Click the "Update" button, then click Next
CheetahUnlocker will flash a normal working radio to your phone so that it operates normally. After it is finished, the phone will reboot and load as normal.
Congratulations, your Treo 750 (Cheetah) is now unlocked, unbranded, and ready to go!

Thank you for your contribution! I applied this to my 750 that was sitting around doing nothing so that I can give it to my niece. I haven't been able to test if it works yet as I don't have a SIM for another network. Everything went as you described so I am crossing my fingers.
thanks man it worked like a charm.... i also cant wait for your WM 6.5 cooked rom.. it will be off the chain
Hi,
My brother just gave me his Treo 750 to replace my broken Hermes. I'm trying to Hardspl this device but without the need to hook it up to the computer. My brother lost the usb connection for the Treo. Is there a way I can flash the Hardspl with a MiniSD card? Please help cause this official WM6 on here is locked to UMTS only...cannot change to GSM. Any help will be much appreciated. Thanks in advance.
newbie
several days ago i upgrade mytreo from wm 5 to 6.5, but for several item didn't work such a camera, button, & can't switch to silent, & can't turn off (at the red button), & can't read mini SD 2 GB,need for the info to fix it, how should i do?

Read through the threads on the version of the 6.5 ROM you used. Some of the issues you are reporting are known bugs in various versions of 6.5 that have been posted.
For example, navenedrob has indicated he will be publishing an update to his 6.5 ROM which has fixes to most of his ROM's reported bugs, one of the major of which is the 'red button' issue you are experiencing.

Damn... I walked around and around and solution was all near me and able to do it myself...
Ok here´s how I done it.
First, I must explain what was the problem.
After update the firmware (not actually upgrade, I had the phone full of trash, so I decided to reflash same firmware v2.18 PTG), the Qtek 9100 / HTC Wizard freezed at 2nd splash screen (the one that shows OS versions IPL version, ect). Tried many different versions, upgraded to 2.24, 2.25, downgraded even to 1.6.7.3, but always same problem, freezed on second splash screen. I read many topics on xda-dev, and seen some people with same problem. Apparently there was 2 solutions. 1- send phone back to warranty. 2- write backup ROM from SD in bootloader.
Passed more then 15 hours asking for this SD backup everywhere, and COULDN´T find any help. Apparently no one had this "SD dump ROM Backup".
So here´s how I solved my problem
1- I tought that a SD backup was needed, and yes it is. But u can use your own phone and your own SD to do it.
2- Get a clean SD card (in qtek 9100 / Htc Wizard case is MiniSD) with 128MB (some people say 64MB, but I personally used a 128MB, maybe a 64MB is enough)
3- Kill (task manager) wescomm.exe (this is related with activesync installed on your PC). Insert the blank SD card on the phone.
4- Get your phone in bootloader mode. Like this : Phone powered off, press Camera button + Power On, will enter in bootloader mode (RGB screen).
5- Now connect your USB cable to your phone. And start MTTY_updateROM.exe (http://wiki.xda-developers.com/uploads/romupdate.rar). After open, on Port selection, choose \\.\WCEUSBSH001 and press OK. A window will open with a blank sheet.
6- Type "r2sd all" and hit enter... wait to the end (at end shows "cmd>"). On your phone screen u can follow backup progress... small bar will appear down the RGB screen.
7- Power off the phone (or remove battery), enter bootloader mode (camera button + power on) and this time RGB won´t appear right away. Will ask if u want to "download SD image", press voice dial button to agree, and writting will begin. Wait to the end. Power off and power on normally. Now your phone should be working ok. Not even needed to reflash the phone after this.
Thanks to all and hope this helps more people with this problem
I can get the MDA in a bootloader mode with the RGB screen but I can't figure out how to get the SD Image Boot. When I open updateROM, it only gives me the seletion of COM1 and COM3. I can't gete any farther, help plz. i really want to use my MDA
Adam
Adam, you missed a step
Kill wescomm.exe as described in step 3 and you will be able to access via USB.
3- Kill (task manager) wescomm.exe (this is related with activesync installed on your PC). Insert the blank SD card on the phone.
not work with me; so sad what i can do?

CID unlock?
I believe that your phones aren't CID unlocked.
I think that only CID unlocked phones or inputing the BOOTLOADER password will allow to backup wizard to SD card
I've got the exact same problem, phone freezes at splash screen. Now I backed up a rom from a working cid-unlocked wizard, but after I tried loading it on my wizard it says 'don't allow update'. So what can I do now?
Awesome solution! My MDA vario is back from the dead!
Thank you for sharing this great solution with us

I was forced to buy a multi-card reader to get my card back Fortunately that they are so cheap these days (less than 12€ for 31 diff cards)
Funny thing is that after formatting the card in Win2k the phone still asks if i wish to restore image when entering bootloader mode
cheers
hi
did you slove this your problem ?
i also got the same error
It stoppped asking to restore image when entering bootloader mode maybe because i've been using the card in normal PPC operations and the "r2sdall" area must have been overwritten
Yes, data remain at SD card. Probably need to insert in SD card reader and format under windows system.
About the errors while reading the data to SD, I remind, to try in a fully clean SD card (formatted completly), and yes, might require that your phone be CID unlocked, but that part can also be done easily.
The data that is written on the SD will remain hidden, and are like system files. That´s why no one can share the needed files over the internet or download somewhere. Because can´t get the files out of there. However, if u seen in your file explorer in your phone some file might appear on card root. But also not sure if can copy it from there and later apply on a card and do this procedure.

Hello I think there is no way to restore a Sd backup on CID locked device.
I think the only possibility is to unlock CID with Imeicheck site (the process begin in bootloader mode) and then restore Sd image.

I'll start. Anybody know of another cab file to get rid of the logo with bluetooth? hidelogo.cab no longer works. When I install it and activate it, I get an endless loop of soft resets.
Another thing that's going on is everytime I soft reset, it shows that I have a voicemail, and it only goes away when I check it, even though I have no messages.
I broke it! I hard reset my phone. Then I formatted the memory card in FAT32 to make sure it was good. I then copied the file to memory card. Used the left bottom button and reset spot to reboot device. After reboot, able to press END/Pwr to start update. It goes all the way through the update to only a hair left on the end. At which point I get a fail message.
I have Cingular branded Treo that I use with my T-Mobile sim card. Battery fully charged. Tried this 3 times. If I reset, setup auto starts. If I take mem card out and reboot, I get the colored screen, with 'Serial' at the bottom.
This is what my screen shows:
00018002
CHEEIMG.nbh - FAIL
SPLASH1 - OK
bOOTLOADER - OK
GSM - OK
MICROP - OK
EXTROM - OK
OS -

Any ideas ?

Don't panic.. =)
Let's try a few things. First, reformat your mem card (yes, again) and make absolutely sure it's formatted fat32. Next, copy the CHEEIMG.nbh file over to your card. Now compare the size of the file on the card with the original copy your downloaded and make sure they are the exact same size.
Next, take your SIM card out of your phone. Then put in the memory card, and go through the process again.
Let us know how things progress.
OMG! We now get the "E" icon for EDGE!
Carrier now says "AT&T instead of ATT
I like the new card detect/remove sounds.
a couple of things I noticed so far. the web kind opf stalls out after a while of surfing. I have to disconect then reconect for it to work again. I also noticed that if you install the htc home screen you lose the send button, meaning it won't work anymore you also lose the keypad. it also doesn't come with a streaming app so no rtsp (3gp) streaming. I tried installing the hermes version but only got to 99% then pushes me back to pie
Settings -->System-->About-->Phone:
Software Version - doesn't get updated properly with this ROM.
It stays as it was prior the upgrade.
I noticed that you can now charge the battery via USB
annoying bugs
1) installing and removing programs take more than twice as much time, i.e. Windows Live. when removing it the phone seems to hang for minutes.
2) I've set a password to protect the phone after 10 minutes idle. now after resetting the device it shows an unusual behavior:
first it asks to enter the lock password, after that it should ask me to input the pin for the sim-card. the "enter pin" screen shows up for only a second and goes away straight to the "today" screen, leaving the phone useless.
to enter the pin I have to switch off the phone and turn it on again.
3) starting up after reset seems to take one minute more than before. with the bug in (2) it's about two minutes more...
Looking at the rom after experimenting wit it a bit I found the Htc touch homescreen to alter the devices send hardware key. It somehow alters the reg for the default dial key. Loading the the hermes or kaiser's six button com manager also has no response however it disables the default Dial pad which I regained via hard reset. This rom will definitely take sometime to cook and perfect. I hope they soon release the offical update in which may have more support. However if any this would be the idea rom to start experimenting with in the kitchen
After upgrade it changed my IMEI. Not fully only two last number! Now I have problem with my purchased software :-(

I had the same issue. Make sure that the ROM you downloaded is the full 83 megs. A couple of places only downloaded 26 megs and then stopped, but said that the download was complete. When I tried to update, it was not the full rom and failed. The fix was to load the complete ROM onto my miniSD card and then performing the update again. It installed with no problem. Hope this helps.
Here's another rapidshare mirror of this ROM in case anybody needs it. It's the full 86 Megs, uploaded by me.

With this method I have successfully unbranded, unlocked, and updated 2 Treo 750s that were originally AT&T/Cingular branded.
I spent hours running through multiple threads reading and searching to finally find a solution that worked flawlessly. These steps have been compiled from multiple threads:

(I couldn't find the original posts for Treo750_OS5_2_19199WWE_STD.rar so I uploaded to my own site for now)
1. Download, extract, and run MAGIC_UNLOCKER on your phone.
2. Select both options in MAGIC_UNLOCKER and click unlock. This will unlock your phone.
3. Format your SD card to FAT32.
4. Extract Treo750_OS5_2_19199WWE_STD.rar and copy/paste CHEEIMG.nbh to the formatted SD card.
5. Transfer 1_CHEE_MountExtROM.cab and 2_Chee_Extrom_rename.cab to your Treo 750.
5. Run/Install 1_CHEE_MountExtROM.cab and then soft reset the phone.
7. Run/Install 2_Chee_Extrom_rename.cab and then soft reset the phone.
8. Click and run Start>Programs>Chee_Extrom_Unlocker. Run it about 3 or 4 time and you should some type of error messages. Just OK or X them and soft reset the phone again.
9. Open File Explorer and click the drop down arrow, in which you will now see ExtendROM. Open it and delete the 2 files in the partition folder.
10. Download, extract, and run CheetahUnlocker on your computer. For this part make sure you have an ActiveSync (XP) or WMDC (Vista) connection to your phone. Click Flash SPL and go through the steps for CheetahUnlocker to Flash SPL. Don't worry about any of the other items in the menu.
11. After going through the steps in CheetahUnlocker and the phone, the phone will enter into tri-color bootloader screen momentarily followed by Loading screen...
12. Next, you'll see a light blue screen with the heading CHEEIMG.nhb followed by a few other entries below it. At this point, it will tell you press the power button. Go ahead and press the End Call/Power button. This will begin the ROM flashing. The ROM flashing takes about 5 to 15 minutes.
13. When the flashing is completed, the bottom of the screen will say Update successful and the entries above with the OK seen at the end. Now reset the Treo 750 with the stylus and immediately (during the Palm Logo) perform a Hard Reset. This is accomplished by pressing and holding the End Call/Power button and simultaneously resetting the Treo 750.
14. You will now be prompted to Erase All Data. Press the Up key of the D-Pad to continue and erase the data. This will format the phone.
11. Upon completion, the Treo 750 will continue to boot-up and go through the initial start-up steps and wizard. Once completed, your phone will now be unlocked, unbranded, and updated to Windows Mobile 6.1.
I made this thread to help people unbrand, unlock, and update their Treo 750s without having to waste hours looking for solutions and how-to something. Basically, made it easier for the noobies and everyone else to find everything in one thread.
Hey man Thanks a lot for the noob hand book
I'll try this but i dont know if it's works for me. if you can let me know thanks..
my treo 750
treo750-2.25-att
1.54.27.00
It should work on all Treo 750s!
Just make sure you are not running WM5 on it and its already upgraded to WM6.
It looks like yours already is WM6 from the 2.25.
SO you should be good!
Thanks for the info
I had a Dash, which I upgraded to 6.1 and it was great. Now I have a Treo and have unlocked it but am not sure how to format the SD stick. I must admit to being spoiled using 6.1 and being able to recognize the SD as a separate USB drive. Is there a way to do that with the AT&T version of 6.0? I am not seeing how to format the disk from the phone. Any ideas?
There are many programs you can find to format your SD card to FAT32. Just look around on XDA and you'll find some posts about it.
I just stuck into my computer and did a quick format to FAT32.
Finally a tutorial for this process that I could follow. The other night, I flashed my treo 750 to WM6.1. It didn't go smoothly for me however, and I had to do it a number of times before it "took". After each of the first 2 failures, I had to reflash back to WM6, and start over. I did nothing different, it just finally took. During one of my failures, it even booted WM6.1, but locked up and failed during the initial regional setting phase. It would help if the following section of the instructions were clearer:
12. Next, you'll see a light blue screen with the heading CHEEIMG.nhb followed by a few other entries below it. (WHAT ENTRIES?)
13. When the flashing is completed, the bottom of the screen will say Update successful and the entries above with the OK seen at the end. Now reset the Treo 750 with the stylus and immediately (during the Palm Logo) perform a Hard Reset. This is accomplished by pressing and holding the End Call/Power button and simultaneously resetting the Treo 750. (WHY NOT HARD RESET DIRECTLY AFTER "Update successful"?)

This is accomplished by pressing and holding the End Call/Power button and simultaneously resetting the Treo 750. (WHY NOT HARD RESET DIRECTLY AFTER "Update successful"?)

I guess you could hard reset there but like i said in my post, i compiled the directions from various threads and that's what they said to do.
Were you able to unlock, unbrand, and upgrade the Treo eventually?
Thanks dubLeE so much for the detailed steps.. Here are my comments:
2. Select both options in MAGIC_UNLOCKER and click unlock. This will unlock your phone.
I didn’t do this step since I got my treo 750 originally unlocked.
3. Format your SD card to FAT32.
Succeeded.
4. Extract Treo750_OS5_2_19199WWE_STD.rar and copy/paste CHEEIMG.nbh to the formatted SD card.
Succeeded.
5. Transfer 1_CHEE_MountExtROM.cab and 2_Chee_Extrom_rename.cab to your Treo 750.
Succeeded.
5. Run/Install 1_CHEE_MountExtROM.cab and then soft reset the phone.
Succeeded.
7. Run/Install 2_Chee_Extrom_rename.cab and then soft reset the phone.
Succeeded.
8. Click and run Start>Programs>Chee_Extrom_Unlocker. Run it about 3 or 4 time and you should some type of error messages. Just OK or X them and soft reset the phone again.
OK, what I did is the following. I clicked on the program 3 to 4 times.. Each time I get an error but I ignore, finally I did one soft reset.
9. Open File Explorer and click the drop down arrow, in which you will now see ExtendROM. Open it and delete the 2 files in the partition folder.
The two files are found and deleted successfully.
10. Download, extract, and run CheetahUnlocker on your computer. For this part make sure you have an ActiveSync (XP) or WMDC (Vista) connection to your phone. Click Flash SPL and go through the steps for CheetahUnlocker to Flash SPL. Don't worry about any of the other items in the menu.
Mmm this step faild so I couldn’t complete to the next step!!!!
My Treo restart to the colored screen and then I get a gray screen with a counter on the top left. The counter start until it reach %7 then suddenly the device restart and I get a black screen which I have to restore my previous WM6 original ROM… ok, I personally believe I have to upgrade my SPL… this is my current configuration
CE OS 5.2.1239 (Build 17746.0.2.4)
Software Version:
TREO750-1.16-RWE

Waiting for your advice….
Hey hammod2k, try running magic_unlocker and see if it make any difference.
If not, then do a hard reset on the phone and go through ALL of the steps again. I read somewhere on the forum that some people were having problems and a hard reset first helped unlock and install WM 6.1.
Thanks for your fast reply. I will try it and i will let you know

I followed all the instructions and got to the same thing as you. Now I have a black screen and not sure what to do now as I am not able to soft/hard reset the treo anymore?
What do I do to get out of this black screen and upgrade and unlock my treo?

I cannot get out of this black screen now?
It wont even sync with Active Sync anymore for me to do anything....PLS HELP!!
How can I restore my Treo 750 back and unlock it?
Ok, After longs hours on the computer, I found a way to fix it and load back up the ROM.
I have also been able to do all your steps line by line with success. I have been able to upgrade to W6.1 but my treo 750 is NOT YET UNLOCKED!!!!
I have done it twice. line by line, number by number and step by step. All with ease but still not unlocked.
Can someone tell me how to unlock it now?
I have a Rogers Version

Glad you were able to fix it! Do you mind posting what you did hear in case others run into the same problem?
Why do you say it's unlocked? How did you come to that conclusion? If you were able to install WM 6.1 then technically that means your phone was unlocked (correct me if i'm wrong).

I had the black screen like the other member on this forum. I had to reinstall my previous ROM/OS (after 10 hours of searching on the net for it) successfuly and then followed the steps again you listed and was successful at upgrading with ease.
However my Treo is still not Unlocked. Not sure what I did wrong or what you recommend I do...
I tried the 2 steps of the Cheetah method and then the Magic Unlocker and still not working.
When I insert my SIM it says SIM LOCK
You have tried 30 times, please wait until timeout... What is that or what does that mean?
Im still on W6.1 and followed all your steps accordingly.
omg, pop my xda forum cherry baby, do you love me?
ok, so after years of lusting after a windows powered pda in one form or another, I finally copped a really really cheap Palm Treo 750 here in Australia. When I received this bad boy, it had WM5.something installed on it.
This step by step guide allowed me to fix any problems and successfully upload (on the first time!) wm6.1
do it guys, seriously. if you can install a new program on your machine,then you can hook this **** up.
fo' real.

Where and when does it say SIM Lock? I've never seen this this issue before nor read about it in the forums anywhere.

Really sorry for late reply… anyway, I have tried and yes it worked but I had to do it manually.. First I have uploaded the file using RUUWrapper.exe successfully flashed my ROM to WM6.1
I don’t know what I was thinking of after that to try another ROM made with an uploader called “Kaiser” and I damaged my Treo “BLACK SCREEN”… I got totally mad and I started to search all over the forums to find a solution since I tried to flash back to the original ROM, and tried like 2 or 3 ROMs but never succeeded to get my device boot up
I found a brilliant solution on http://forum.xda-developers.com/showthread.php?t=366771 which helped me to get my Treo up again
Finally it was by falt… but I still don’t understand the differences between :
1) Kaiser
2) Herman or I think they call it Hermes
3) Vouge
4) Raphael
6) Victor
Are there differences between all of them… are they depend on ROM type? What about Treo compatibility with the above types.. because my experience with Kaiser type cooked by someone I cannot recall his name was total failure..
finally i can say it was great experiance
Thanks

But what I don't understand is if my phone is already unlocked and unbranded why I have to go through this step?
Just download ftp://xda:[email protected]/Cheetah/Unlocker/CheetahUnlocker.rar at first.
After you have ran step 1 and you spl is updated (you can check it by pressing the lowest left side button and reset button at the same time, lowest line should say something like 1.4 .olinex).
When you have succesfully done that boot your phone again and move the 6.5 rom image to your phones sd-card. I use this one with app pack http://forum.xda-developers.com/showthread.php?t=541417 and you can read about my experiences with it from the last page of that thread.
After copying the file (should be named CHEEIMG.nbh) to your sd-card just run the step 1 in the cheetahunlocker.exe program and your phone should boot and start to install the rom you chose.
I also needed to update radio in order to get 3g/hsdpa work here in Finland...
Hope this helps and sorry about my bad English
Can not get to 3rd step ("Press and hold "Shift" and "2" on your keyboard and click the title bar of CheetahUnlocker. This will unlock all 3 options. Click the 3rd option "Flash Normal Radio".) This does not unlock all 3 buttons it repeats step 2, My phone asks to install software I accept, but it goes to boot loader mode which disconnects from my computer. What to do?

It's Shift + @ key if you're on a UK standard keyboard - bare in mind the US keyboard layout swaps " and @ around
Im on US standard. Detroit, MI
shift 2
click box at bottom and keep trying the shift 2. It eventually works. keep clicking all over the application screen. it seems the box at the bottom was my solution. I ended up with a radio that was slower on internet browsing. I had to flash another radio.
I am getting my Tilt2 ready to ship back to AT&T. It has a totally dead touch screen. Now I am stuck unable to get the stock SPL restored because it requires a key press to approve the installation of a program from an "unknown publisher" (the standard ROM warning message).
I've also tried using MyMobiler which works great to show your Mobile screen on your desktop and substitutes mouse clicks for screen taps but I can't get it installed either due to the same limitation above.
Another work around would be a self installing cab that modifies the registry keys in HKLM\Security\Policies\Policies to reflect the elimination of the above warning (but crap this would probably trigger the warning itself...)
In short if anyone has a clever workaround for this last step of fully returning my device to original WITHOUT using the touch screen please let me know.
- You don't have total commander installed or some other registery editor? Then you can edit those values yourself.
Maybe you have thought of this yourself but you didn't mention it And I don't know if it is possible but can't you use your hardware keys to approve the installation?

My keyboard works but the Tilt2/Rhodium do not have the variable function keys that are assigned to actions in certain parts of the screen (say like the original Tilt did). That is the main problem. If I had those I would have been done long ago.
Any other ideas? There must be a subtle/clever work around here.... Thanks.

Try This It Might Work For You
Ok - here is a quick step by step for people who want to restore the stock bootloader via SD Card.
1) Download v0.84 bootloader from post 1 in this thread.
2) Rename ruu_signed.nbh to rhodimg.nbh and copy it to your SD Card (Must be 2Gb or less!)
3) Insert your SD card and boot the phone while holding the VolDown button. Flash this image.
4) Upon the next boot, your phone will go straight to bootloader saying "Update ROM Error, Please Try Again".
5) Download any STOCK ROM from the HTC web site for your phone.
6) Run the exe that you downloaded from HTC and then look through the folders in your temporary files for SPL_Signed.nbh.
7) Copy SPL_Signed.nbh to rhodimg.nbh on your SD Card.
8) Insert your SD card and boot the phone while holding the VolDown button. Flash this image.
9) At this stage, remove your SD Card and your phone will either boot or not.
If your phone boots, nothing more is required.
If your phone does not boot, copy RUU_Signed.nbh from the same place you got SPL_Signed.nbh from to your SD Card as rhodimg.nbh and boot your phone while pressing the VolDown key.
This last step is only required if your phone doesn't boot at step 9. It will flash the ROM to your device and should start up as a fresh phone.
Enjoy
^ great, sounds promising. Thanks so much. Are you sure about the 2GB card limit? I tried 6 GB card and it does appear to be a problem. Stuck at "Loading..." (that is all that is on the screen, blue font on a grey background) and it goes there under a normal boot or under entering boot loader with vol down key from reboot. Ugh... Any advice, am I bricked?...
Update. Despite seeming like this did not work it seems it did. To be precise I only got through your steps 1-3. Then to "recover" I simply reloaded the official HTC AT&T ROM (again) with the single (again official) .exe over USB while in boot loader mode. It loaded fine and now claims I have SPL 0.87 (I used that instead of 0.84 figuring there were pretty much identical).
Thanks again! Greatly appreciate the tip!!

Yes, before working on getting the SPL back I also previously used the official one step HTC/AT&T ROM restorer which flashed ROM and Radio. 6 GB card must have worked.
I was updating my post as you quoted it...
