My device is in good condition and running WM6 Black, however, I got a new job that provides a PDA phone, so Im wanting to sell my Cingular 8525 (walking around with two PDA's on my belt is a little much). Before I sell my 8525 I want to put it back to Factory setting so whoever buys it doesn't have problems from cingular. I've read through the forums and couldn't find anything about downgrading a device. I went to HTC and got the latest official rom from them for cingular, but before I try to flash that I just want to make sure it wont brick my phone because of the upgraded Radio and SPL that I have. I need to know if it will put the radio and SPL back to factory versions? if not any way to put everything back to factory/offical cingular release. My device info in listed in my Sig. i'm sorry if this is posted somewhere else, i promise I read through every search result and looked through the wiki. Please help? (unless someone wants to buy a moded 8525 ;-) )

its the SPL I'm worried about, I've read on here before that when sent back to cingular/HTC for repair or what not that the warrenty was voided and the customer was charged for a new phone because it had a forign bootloader/spl. thats what worries me a little.

You'll have to downgrade the SPL to 1.10 or less first, otherwise that factory ROM won't overwrite it. This is clearly detailed in the Hard-SPL release notes/thread (see link in my sig).

I've downloaded ruu_hermes_1.34.502.1_1.16.00.00_wwe_cws_ship.exe from HTC website for cingular 8525. Should I flash that first, then try to find a factory SPL to flash, then flash the cingular rom again to get the SPL back to what the current released spl/rom settings are? Where do i find the factory SPL, I only see Hard-SPL-V6.zip.

To repeat, Hard-SPL > 1.10 purposefully prevents overwriting the SPL (as do the factory SPL's > 1.04). The downgrade guide doesn't address this, unfortunately.
You'll need to downgrade to Hard-SPL 1.10 (yes, there's something other than V6 still available), then reflash the factory ROM or your repackaged radio/SPL nbh.

I downloaded SPL-OliproMFG. extracted. used koch to make the nbh with the SPL.* file (not the SSPL file) and the ruuwrapper to update the phone. I chose SPL-1.11/1.13/1.30/1.40 New bootloader because thats the current SPL on my phone (SPL-1.40) with the option Hard-SPL checked. It connects to the phone, transerfer 100% and resets the phone. After it boots I press the okay and power +reset and it still showes SPL-1.40.Olipro.
Did I download the wrong file or am I using the wrong settins on the RUUwrapper? I'm doing my best to read through everything and actually try, that is what i'm told will not piss off the senior members, you are willing to help those that try to help themselves. so I appreciate everything you guys are offering me. I just wanted to let you know that.

Yes and yes. Use the Hard-SPL link in my sig to get 1.10 - Olipro SPL (a.k.a. "flavour 2"). You have to force SSPL when flashing it, otherwise it won't downgrade (for the same reason your factory ROM isn't downgrading it).
To flash the old spl, put it into an nbh image as in the guide, when you flash using RUU select force SSPL. voila
Everything is back to normal and working GREAT! Thanks for all of your help!

Perhaps you could update your downgrading guide to reflect this? I see "Why didn't my SPL downgrade?" questions all the time.
Also, IMO when reverting to "factory", one should downgrade SPL last, or at least separate from the radio. By doing so, you would retain the anti-bricking and "quick flash" (if > 1.10) benefits of Hard-SPL while flashing the radio, which as we know is the most risky.

Agreed, except that if one has Hard-SPL > 1.10 installed on their device (which so many do at this point), they can't just repackage SPL.nb from the original factory ROM per the guide and expect it to downgrade (which is what krisg0 encountered). Same holds true for factory SPL > 1.04.
Thought perhaps you could take the guide one step further to say that if you have Hard-SPL > 1.10, you must downgrade to Hard-SPL = 1.10 before a factory SPL flash will overwrite it. I believe this to be the primary reason Olipro left v1.10 available.
IMO, adding this bit of info to the guide has the potential of cutting down on a lot of "How do I downgrade my SPL?" questions.
It's your guide, of course -- just thought I'd offer my 2 cents for improving it and maybe even eliminate some repetitive questions on the forum...

You dont need to downgrade the SPL twice, simply package the old the SPL into the nbh image then flash using customRUU....select force SSPL and it WILL overwrite the SPL regardless of the version you currently have.

OK, yeah, that would be the more direct route when disassembling and repackaging the factory nbh and downgrading in stages. I just didn't see anything about forcing SSPL on the SPL part, that's all.

well that is the only version # the program gives
i cant seem to get to bootlooader mode to find out more
and if i do decide to flash to that spl, all my data on the device is still there right? it only wipes when u upgrade the rom?
i really really only want to upgrade the radio. is it perfectly safe to do the upgrade without hardSPLv7?
Someone Please Tell Me
i wouldn't upgrade ANYTHING without hard-spl
read EVERYTHING at http://www.mrvanx.org/cms/ before flashing
if you don't, please don't come crying here if you brick your device.
btw, not flashing the radio properly WILL brick your device
I seem to be following SkyyBoy in posting recently and giving some of the same advice.
You can flash a radio without hardspl and it is safe as long as NOTHING GOES WRONG. If something goes wrong during the flashing process (such as power failure, PC BSOD etc) then you have a $500 paperweight.
If you put hardspl V7 (or 2.10 - same thing) on your phone before flashing radio then if a problem happens you can recover the brick.
No one here will recommend flashing the radio without hardspl.
Why are ytou reluctant to put this on your phone? If it's for warranty reasons later, this can be removed (also in Mrvanx's guides I think).

You need to read up alot more before trying to flash anything.
Flashing an SPL or a Radio does NOT lose your data.
MOD WARNING: There are reports of this damaging phones, DO NOT USE until a fix is provided.
Further edit:
A member has reported :
"those with a SPL lower than 4.0.0.0 or something like that gets bricked. I just wanted to get this first post edited to reflect that so that people don't keep bricking their phones."

Hard-SPL for Herald is released!
if you somehow manage to kill your phone in the process of doing this then tough, it's not my fault.
once the SPL is on, it will protect itself from being overwritten.
the SPL is hardcoded to allow unsigned code and ignore your CID.
someone reported it somehow simunlocked their device after flashing an HTC brand ROM which is possible, but I doubt it.
When flashing, the RUU will go to 100% and your device will restart but the RUU will give an error; ignore this and close the RUU. to confirm, just reset into bootloader and check the version
PLEASE NOTE: THE DEVICE MUST BE SYNCED WITH ACTIVESYNC, DO NOT PUT THE DEVICE IN BOOTLOADER MODE MANUALLY
Olipro
Differences g4 and h3 only for IPL.
SPL one for all chip.
USPL for Herald is made but is not published while.
Ask pof.
While we prepare new version - SPL and haret in one file.
Much problems when files apart -see thread USPL for Artemis and ELF.
the device has a DoC, so you can read/write it with the appropriate pdoc tools.
any takers?
sorry mate am quite busy atm, although if there aren't any volunteers in the immediate future I am sure I could work something out with some instructions
cheers
Here's the beta version of USPL for herald, I did it a while ago but received few feedback: only 1 wing user (Paul from modaco) reported it working.
As beta, this does not flash SPL on device, to use just put the NBH you want to flash on the RUU folder and start herald-uspl.exe
Please report success or failure, remember it's beta, use at your own risk
I leave the final "Hard-SPL" version to you Olipro

I prefer more safe method flash - original.
The Original flash allows to avoid the many problems -a choice of the addresses, model DOC etc and more correct.
Also any developers can use uspl.nbh and select spl for use in their own ROM.
In any event you may take for base spl and use in your tools.

flashing a few hundred KB to the DOC is really not a bloody issue. and could you please explain what the sodding hell "original flash" means, since I would like to point out that the idea is to generate an SPL for the two separate DoC types.

Hello,
I used Step I nivid to downgrade to wm5 before I upgraded to wm6 from kamalneet, link to this post http://forum.xda-developers.com/showthread.php?t=349603
But I have some major problem with the rom, when I now want to donwgrade back to the official WM5 from my provider O2 it always says that the nbf file is to old and i have to get a newer one.
This problem only occured after I used "nivid wm5" in kamalneet's post for downgrading.
I can downgraded with different "Step1" Roms posed in this forum but not with the original one as it was possible before!
And also after downgrading with one of these roms the error message keeps the same!
Is there any way that I can get my original O2 rom back?
Thanks!!
search for HardSPL and flash it! after that your SPL Version will be: 2.4G.4PDA THEN!!! you can downgrade to ANY SPL. just flash latest o2 ROM and you will be back at SPL 2.20.0001 again!
i've tried it already it REALLY works!!!
i just flashed back to my dopod original rom.
Original rom is still the best.

Yep, just as nForce said:
You can use HardSPL.
But if you want to set it all back to the old-fashioned original-values you have to go through an even looooonger way (have done it by myself) - you have to go down to IPL 2.10 or lower to have your device back to IPL 2.15 from original O2 ROM, otherwise it remains 2.20 or higher *caugh* -
but then it's back to original in every aspect.
You have to go into SoftSPL (that whitescreen), then from WIKI back to IPL 2.10 (see wiki), followed by going back into SoftSPL and with whitescreen to SPL 2.15 or lower. After that you can take the nbf from the O2-Upgrade-File and flash with the ROMUpdateUtility_NV_G4.exe from Upgrade_Package.zip.
Just take the nk.nbf from the original O2 Firmware (after starting somewhere in %TEMP% or by extracting setup-file), then put it in "Upgrade Utility" flash it and boot will say:
O2-Screen
IPL 2.15.0001
SPL 2.15.0001
GSM 02.19.21
OS (don'tknowexactly)
regardless of which version you ever have had flashed onto your device before.
Happy flashing.
offtopic: what are these I/SPL 3.0something versions for? Just for preventing going to other ROMs?
Not HardSPL but SoftSPL
whoops... it's even easier than that.
regardless of IPL and SPL-Version just follow the steps to get into SoftSPL (the White-screen) WITHOUT flashing HardSPL
Then do the firmware-update from O2 (the O2-shipped-one) and everything should work fine. (after this procedure your phone should look like a virgin, with no HardSPL, with CID-Lock (if not unlocked before), original ROM and ExtROM)

Thats how I made it and it has worked perfectly!
Thanks for all your help!!!
First, my problem started with either updating to the new JFv1.43 recovery, or flashing the new SPL from Haykuro.
Symptoms:
1. Everytime I flash a new ROM, wipe or no wipe, I come back stuck at the T-Mobile G1 boot screen. The only way I've found to get through is to take out battery and boot into ADB (the Camera + Power screen) and "fastboot flash boot boot.img". This almost always work.
2. Nandroid stopped working. Nandroid always errors during the process of backing up, and I'd only have splash1.img and splash2.img in the nandroid folder of my SD card. Kind of want to try reflashing the JFv1.43, or even go back to 1.42 (can't find) for troubleshooting. Also not sure if this would affect the new SPL and cause a brick.
3. "Insufficient storage available" with Dude's and Cyanogen's builds. I'm not sure if this one is related to recovery or SPL. This might be caused by past attempts at doing apps2sd (I've done both symlink and unionfs).
Anyways, losing Nandroid has lost me a lot of time with trying out new ROM's, I'd really like to get it fixed. The boot stuck is a nuisance, but much less troublesome than losing Nandroid.
Its the SPL.

I'm not positive (***so dont do this without researching***) but i think it would be possible to flash to a different one ( i mean, you flashed another SPL over the original one, right? ).
There is a "mega-thread" that has information on all the SPL's and their features/updates. If the info is anywhere, it's prob in there. Search in the Dev forum.

I could be wrong, but the key is not flashing an older RADIO with the newer spl.
You should still be able to go back to hardspl with no issues.

I have flashed from the New H SPL to the HardSPL i originally had on the phone when I found out people were having trouble with the SPL. I install the NEW SPL again to run Hero, but you CAN flash it back to the older SPL I would recomend HARDSPL though.
*not responsible if this doesn't work but I was able to do this without any trouble. Was just a bit nerve racking.
i am 99% sure the above post is correct, don't flash a different radio, but you can flash another SPL right over the Haykuro SPL. i would double check that as there is a 1% chance it will totally screw your phone and i don't wanna be the guy that told you to do something that bricked your phone, but it should work. just to be safe you should make sure splash1 is the t-mo g1 screen so if it stops you can call t-mo
i flashed from the latest haykuro spl 1.33.2005 , to the original t-mobile spl HBOOT-0.95.0000. I fastbooted and it was showing the original spl installed.
I have a custom ROM on my device and I need to go to T-Mobile for warranty.
Can I install a T-Mobile ROM, T-Mobile_HD2_MR_Software_2.13.531.1.rar, I downloaded from their website, without creating any problems or bricking my phone?
I not asking for any guarantees, just a professional opinion.
Thanks to all for all the great work.
run hspl3, choose 2.08.0000 this will remove hspl, then flash the rom you mentioned, (just run the .exe, no need for sd card) which will return to stock the rom, radio and spl
I'm not an expert by any stretch but from the research I've done I would surmise you have to A. Change back to SPL 2.8.0000. I just changed my HSPL back to SPL 2.08.0000 based on the answer to my thread and then B. reflash the TMOUS stock ROM. I have read that reflashing the ROM will revert the SPL from 2.8.0000 to 2.10.000 which is where I started. I have seen people state that even after relashing the SPL is still 2.8.0000 so then the next step is flashing from the SD card as instructed in the tutorial on the HardSPL exe file. Hope this helps.

I just installed the stock TMO ROM and my SPL is back to 2.10.0000, just as it came from the factory so I am good to go!! Thank you samsamuel, your instructions were right on!
Thanks too All
I will charge the phone up tonight and get er done tomorrow.
Just curious, what would happen if I installed the T-Mobile ROM without removing HSPL?
Thank you all for the help.
