extra how to: how to restore Stock SPL for warranty reasons.
step by step:
- this is ONLY for warranty reasons. i.e. the device needs repair and you have to send it to htc to get it serviced. if you plan to restore hardspl then don't even bother flashing this stock package, unless you are some kind of hacker/dev
- IMPORTANT: be sure to first restore stock OS, and stock radio. stock SPL is always to be done last!!
- now the steps
1. download the stock spl package from this post.
2. download X1_HardSPL_v1 too, from this post.
3. run the hardspl package, but do not press Next button i.e do not go ahead with flash yet.
4. at this point, take the extracted stock SPL, a RUU_Signed.NBH file, and overwrite the other RUU_Signed.NBH in hardspl package.
5. go on with the RUU (or if needed, run SSPL-Manual.exe manually, then run RUU when it goes to tricolour screen with 0.52.OliNex version), it goes to 100%, reboots, done.
+1. to verify, enter bootloader (see description above in this post), and check version number on tricolour screen. it should say 0.72.0000.

Found it here, @ the end of the first post.

Thank you for all your help
well after not sleeping all night yesterday now it's working
i don't even know how it began again to work
i did a flash of a stock rom it stopped at 10% then a hard reset (didnt work initially) then flashed again hardspl and it could do the hardreset.
im si happy it's working again
i don't count that much on se warranty
thanks again

Sometimes the problem is in the incompatibility of Hard SPL with your ROM. Same happened to me with Diamond. Only flash another rom and problem solved

If you can find the dowloaded .nbh file on your machine, you can copy it to your microSD card, rename it to Kovsimg.nbh and flash from bootloader that way.
However I couldn't find where the SEUS was saving the file.

Well my problem was very strange because i could flash the firmware through microsd or RUU successfully but it didnt boot. It just showed the logo for some seconds and rebooted again. I also tried many commands with mtty like task 28, task 2a (which make it just appear a white screen and nothing else). anyway the only thing to make it work was to hard reset and then flash the hardspl again...
after flashing the hardspl the hardreset began normally.

Does anyone know how to do the hardspls - Yes it should go to tricolour screen now and say 0.52.OliNex.MFG (this is SSPL!).
but then the error message is coming and no
"Hard-SPL flashes, device automatically reboots, job done"

HTC Pure won't boot, flash stuck at 0% HELP!!

Please help, I was uninstalling some applications from my HTC PURE and had to restart the phone, when it was rebooting it hung at the ATT screen and there was small red text in the bottom left screen.
I had previously installed HardSPL 1.83 but relocked it via instructions in 2nd post because I'm still deciding if I wanna keep the phone and didn't wanna do anything for warrenty reasons.
I have the stock ROM and never installed anything except the HardSPL and the revert.
Please help me, I have tried to load the ATT Pure Stock/Shipped ROM I found here but everytime I try to in the bootloader mode it says either "no image file" or hangs at loading depending what I've tried to name the file. Also I've tried to run customruu.exe to install the stock ROM and also tried to install HardSPL 1.83 but it hangs at 0% and eventually wants to do recovery on the PC.
How do I fix this problem, and preferabbly get it back stock. I do have a warrenty, well unless I violated it by installing HardSPL then doing the revert.
Thanks

Of course you hard reset?
Make sure your SD card is formatted to Fat32 and you may mant to try a different card, 2gb - 4gb.
What does your SPL say now in bootloader mode?

Yes I tried a hard reset. I can try another sd card the one I used was fat32 and 2gb. I believe it says 1.33 can't look now but I know it's not the same as an untouched pure.

Help!
You are not the only one who is having this issue. I am frustrated beyond frustrated. How are other people flashing their out of the box ATT Pures using the same exact steps but I can't? It's making no sense.
1. I turn off firewalls.
2. I've tried both usb and sd card boot, didnt work
3. I installed the enablerapi cab
Nothing works and I am having the same problem you are having...it stays on 0% forever and it doesnt even prompt me saying there is an error it just sits on 0% until I unplug it...
Help!

Are you trying to HSPL or flash a ROM?

Well
According to what i've read, you have to do Hard SPL before you flash a rom, so i've been trying to HardSPL and it doesn't work! I even tried to skip the step and just flash the rom and it doesnt work..
Now, I also have an ATT Tilt to and I JUST flashed a rom 30 mins ago, so it has nothing to do with firewalls or anything as far as my computer goes, I think its the phone, so what can I do?

How to flash HSPL.

Its a good thing flashing the ROM didn't work, you'd be bricked.
For flashing HSPL, it seems that newer phones are having an issue.
Something may have been changed that is preventing the unlocker from working.
Do the following;
1. Hard Reset
Instructions:
- Soft reset with stylus
- Hold Vol up & Vol dwn simultaneously until white screen appears
- Following screen prompts, Press Vol up to confirm.
2. Go to bootloader mode.
Instructions:
- Turn off your device using the power button
- When the device is turned off, simultaneously press the Vol dwn + Power button
- Your device will startup in Bootloader mode
Should say SPL: 1.33 or something.
3. Sync your phone to your PC.
4. Install enablerapinew.cab
5. Unzip both Topaz_CustomRUU_v1.1.zip & SPL_183.zip to the same folder
6. Run the CustomRUU.exe
This process should install HSPL and now when you enter bootloader mode you should see something like SPL: 1.83 Olinex.
If so, you're ready to start flashing custom ROMs.
If not, please report all errors to the HSPL thread or PM Olipro.
**I take no responsibility for any loss of data or functionality of your device.**

See, the problem with your instructions are...
1. You cannot soft reset with the stylus, I don't see a button anywhere on the phone ( ATT PURE not Diamond 2 )
2. Holding Vol up & Vol down simultaneously until white screen appears doesn't work. The only thing that works is when I hold Vol Down and the screen with the colors come up, not a white screen.
So i'm still lost. Thanks for your help regardless. I just really want to flash a new rom so I can stop using this stupid slow ATT rom.

So basically you are messing with your Pure and don't know how to soft reset?
Remove the stylus and in the groove for the stylus is a red dot, that is the red reset button. Insert the tip of the stylus in the red dot and push. Now the Pure will soft reset.
Probably should familiarize yourself with the device before you finish turning it into a brick!

Oh wow. That is so hidden.
On my Touch Pro 2 its right there on the side where you can see it, with words.
Anyway, Thank you very much, i'll try that.
Still, what about the Up and Down button volume button function so I can go into bootloader mode?

Now that you found the soft reset button.... follow my procedures.
Note- you have to hold the keys IMMEDIATELY after soft reset before the boot screen appears.

Ok.

Didn't work, I re-did the steps you listed 3 times over to make sure I was correct and the same results. I guess ATT has found a way to stop their phones from being unlocked.

You should probably post over in the HSPL thread.
You'll get more help over there. There are many others having similar issues and there may be a fix over there.
FYI, when you get to the tri colored screen, that is where it shows what SPL you have currently.

Updating rom freeze
Hi, I don't post much if at all, normally you guys have it right on the button, this is my 3rd phone to run custom roms on but for some reason it just freezes on the "Updating ROM image on your PDA Phone..." screen and doesn't continue past, on my last 2 phones active sync worked well with updating to custom roms,seems like my Pure produces the same error after the attempt, its a communication error "ERROR [262] : UPDATE ERROR", now recovering from the error is not a issue, we all have familiarity in that area but I was wondering if it could be something as simple as the cable that was sent with my phone or if its possible to flash rom through sd card as opposed to using active sync?

Yes, you can flash through storage card, just rename the .nbh to TOPAIMG.nbh, Put in root of storage card and enter bootloader mode.
You have HSPL'd, right?

I was just going through the thread. I have the same issue. i have place topaimg.nbh in the root of storage card and entered bootloade mode, it shows loading and is stuck at 0%.
HSPL is 1.83. Went through entire thread of HSPL but unfortunately didn't find any solution.

Just to confirm, you have to name it exactly "TOPAIMG.nbh".
With all of the people that have tried all methods and still can't flash, something must have changed in the stock SPL.

From HTC site (HTC Pure support):
What is a Soft Reset and how is it performed?
A soft reset basically resets the memory structure in the handheld. This recovers the device from memory conflicts, corrupted system service chains (mainly due to attempting hacks), memory leaks, and system lockups due to the “Fatal Exception” program errors. Removing the battery from the device while it is still powered on is NOT a soft reset and can actually damage the device.
A Soft Reset is performed by:
Remove the Battery cover and the Stylus from the device.
Insert the tip of the stylus into the Reset hole located at the entry point of the stylus silo.
The device will reboot.

1. Turn on your phone normally (i.e. not into bootloader mode)
2. Connect phone to pc using USB cable and select activesync mode.
3. Follows instruction as above in post #4.
Hopes it helps

i did it exact that same way. but nvm i fixed it now.

[Q] Pure bricked?

I don't know if this topic is covered but I could not find and exact thread for this.
I used an HTC Pure on AT&T for some time and I flashed several ROMs as they were updated on XDA. I recently switched to Verizon and HTC Incredible and wanted to try and sell my Pure. What I did not do before I ported my number to Verizon was reset my phone. Now that the existing SIM card is invalid, I tried flashing the phone without it to the original AT&T ROM for Pure. Apparently there were some issues and the flash did not complete. I tried flashing it to cooked ROM (Energy) but still the flash did not complete.
The flash starts properly and then midway the phone restarts and I get a message saying that the update was not successful and that I should try again. Same thing happens when I try again. This message shows up on the boot screen (tri-colored screen). I have tried flashing via the SD card and CustomRUU. The official ROM comes as an .exe and I run is on my computer and the same thing happens. Sometimes it just keeps repeating the update process on its own erroring out every time before restarting the update process (on its own).
I don't understand any of this so I turn to you guys. Please let me know how I can fix this, if I even can.

Flashing w/o the SIM should not be an issue.
At what point during the boot process does it freeze? On the HTC Startup animation or bootscreen?
It perplexes me that the flash doesn't complete.
I am going to suggest following;
1. Take out SIM and SD Card and battery.
2. Replace battery and perform hard reset.
3. Take your stock ROM .exe, right click and extract to a folder on your PC.
4. Download the enclosed Topaz Task29 and unzip to your PC.
5. Replace the .nbh file in the Topaz Task29 folder with the RUU_Signed.nbh file from your stock ROM.
6. Go into Bootloader mode while connected to PC and wait for USB to show on the bootloader screen.
7. Run Task29.
If you are trying this from a Vista or Win7 machine, I suggest trying to find one running XP. Also make sure your battery has 50% or greater charge and turn off all AVs and hibernate and\or screensavers.
Hope this helps.

hey thanks ... i'll try that tonight and update here ... the flash process never freezes actually ... what happens is that the flash does not complete in some cases and restarts my phone .. goes to the bootloader screen and when it says either SERIAL or USB ... it gives the error message above ...
of course there was a time in this whole process when i did get the flash to complete ... at that time the boot process froze at the HTC screen ...

What SPL are you currently on? (baardya)

Didn't get a chance to try Bruce's solution. Will do that tomorrow.
I have 2.51 ... (cant be sure of the number, but i have the one higher than 1.83)
'Incredible'ly, Baardya

I performed the steps mentioned and flash was completed successfully. But on the restart, the phone freezes at the AT&T World Phone screen. It does not move ahead. Any ideas?

that happened to me a while back, try hard-reset, remove sd and sim, flash again with RUU, hard reset once more, replace cards.
Also try this cab (i know I had to use it at one point, might have been for hspl though), forget exactly what it does, but Bruce might know.

After i wrote the above message, I tried to flash the official ROM again, without the steps mentioned by Bruce (just directly) amd I believe it worked.
Thanks again.

hi there mate, Im no expert but I had the same problem.im no expert and you may have to wait for expert advice,....but......
I reformatted the memory card with MiniTool Partition Wizard Home Edition 5.2 it reformatted the card slowly, you can search the forums for" format card"and download a proper formatting programme.
I also had problems with the actual download once, i kept having the no image error come up over and over, so i re downloaded the file and it worked ,....also when they say take the battery out and wait,...do it for 10 secs.

hm, not sure if I'm 100% with you, but lets try:
the output you describe (SPL-0.78.0000) clearly shows that you are still on the latest stock spl, which you either got by factory default or through one of your later updates through SEUS (depending on how old your phone is)
this (stock spl) automatically prevents flashing of customizes roms (like the mentioned Energy rom), all you can flash with that are stock roms
there is the hard-spl thread concerning this by olinex which you most probably read and tried
so as I understand it you failed at flashing the hard-spl, then tried to run SEUS which failed as well and now you cannot even start your phone?
after failing at SEUS did you retry to run the SE update utility? it sometimes fails before successfully completing
did you try putting a stock rom on your sd card and flashing this (that would delete personal items and settings not backed up)?
how did you try flashing hard-spl? synching your phone with your pc and launching from there?
Best, DK

hi,
thanks for your post, and for trying to help. i should mention that i have never sync the phone with pc, i never need this. and i tried to hard spl the phone, but also gives error, it shut down. from then i tried several tims to do the update with the sony-ericsson application, it check's the phone and said that i have the latest software, but if there is any problem, try reinstaling the software. i push the reinstall button, it starts reinstalling, but the bar goes between 10 to 25, other time even 60 %, and then gives the communication error, and sais to try again.
i am no expert, this is the first time i try to do this on a phone, so if there is anyone who is so kind to explain step by stpe what i have to do, i shoul thanks him verry much.

So you want to install custom ROM to your phone? you need hardSPL first
If you have it hardSPL it will show 0.7.2.ollinex
then you just flash it. Try google how to hardSPL and FLash
simple mechanism,
X1 (Stock ROM and Stock SPL) -> hard SPL -> X1 (Stock ROM + hardSPL) -> Flash custom ROM (Energy ROM) -> X1 (hard SPL + Custom ROM)
WHY should Hard SPL?
because as DK explained above, SPL is the bios of your X1 and won't accept any ROM beside Stock ROM. so to have your X1, you need to change by doing Hard SPL, it will make your X1 accept any kind of ROM, stock or customed.

is it better to upgrade Stock ROM and Stock SPL to install applications? sorry, i'm just new in SE phone specially x1, so many things to learn here..

They're both the same. Applications will install fine on a stock rom as well as a custom rom, there's NO difference. Think of it as jailbreaking an iPod Touch or iPhone, they can still install apps from the app store with no problems, NOTHING is changed.
In fact, think of it as a car. An normal car uses petrol. A car with a modified engine ALSO uses petrol. So there's no difference.
The difference between a stock and custom rom however, is huge. A custom rom is basically a stock rom, but modified. Custom roms gives you more customizability, just like jailbreaking an iDevice. Most of the custom roms run more efficiently, and a lot faster than a stock rom.
It's NOT hard to install a custom rom, you just have to read the guides properly and follow the simple steps. It's worth every bit of your time. Just follow the 8 steps here to install hardSPL:

And btw, the SPL thing is just the same as a jailbreak. It's a hack basically. Installing hardSPL will jailbreak your device so that you can install custom roms on it, it's basically "unlocking" the device so you can do whatever you want with it.
