Scared to post but I am stuck must take your wrath

Aloha everyone,
I have tried to not post for about 3 weeks but I just can't move forward. I have read and tried to follow everything on the site but I am just confused. I know this is a developers site and I am very intimiated to be castigated by you guys but...it's the internet so what the hell.
I have found numberous instruction threads pertaining to updating ROMS on the Wizard. It seems that up until recently there was only one way to do things but now there are many. As I try to answer questions I come into conflict over which way I shoudl be heading.
I currently have a working WIZ100 that boots with IPL 2.21.0001 SPL 2.21.0lip with GSM 2.25.11 and OS 2.25.11.1. I somehow got to this point, I think by following the instructions to get hardSPL on my device and booting on startup. I did not know if I next needed to find a ROM and if so then how to get that ROM activated on my device or what programs to do this with. I know that the threads spell it out but the threads pertain only to direct assumptions; the assumption that my head is not in my ass.
I wanted to attempt to put a new rom on here, for fun and to play around with something new. Perhaps increase reliability or to get WM6 going. I am stuck now though. Part of me wants to turn back and load the original ROM from the HTC site and the other part of me wants to try a new ROM as I already have this thing booting to the 0lip SPL.
Is anyone out there willing to help me either via this thread, personal message or IM?

Since you have already installed Hard SPL you should be safe to go ahead and pick virtually any ROM you choose on there. I don't have a lot of experience with Hard SPL yet, except for installing it on my kaiser, but the one thing I would guess that you should make sure that the ROM you want to flash doesn't have would be an IPL/SPL update included. As far as I know, I don't think any of the public ones that you find on here have them but make sure you read the chef of the ROM's entire post to make sure. And, if you magically happen to find my ROM somewhere, which you shouldn't since I only gave it to 2 people to try, don't flash it because mine does include an IPL/SPL update.

From my best understanding you have already loaded HardSPL and now are CID unlocked. If this is the case then I would recommend going forward and flashing a new rom to your device. Just go to the Wizard Mobile 6 thread and find one you like, and flash it.
Simple as that.

I appreciate your replies.
1) I am clarified like butter! What program do I download and use to flash the ROM to the Wiz, this has been a source of confusion for me.
2) If I download and install the HTC Cingular ROM from HTC, will that overwrite the HardSPL and return my phone to Factory Default, including the radio areas? In other words do I rid myself of 2.21.0lip?
Thanks for not beating my head in...very polite you devs are...

I like beating people's heads in, and you are far too polite, that I am actually having a very slight guilty twinge! Damn you. I have a G3 myself so I cannot help much, however, I found this sticky which may help.
http://forum.xda-developers.com/showthread.php?t=332320
I do know that once you choose your rom, you open the folder and run the item marked as ruu.
Now if you only had a G3, then I could fry you like the noob you are.
I suppose at some point, I should make a point of reading/learning about G4's. I know they are a far different animal from my G3.

That's the reason I said not to flash a ROM that contained an IPL/SPL upgrade since there is the possibility that it may overwrite Hard SPL, although I'm not positive of that, but better safe than sorry especially if it it's not an official ROM that carries the correct IPL/SPL format for a G4. If it doesn't contain the correct format for a G4 it could ruin your phone. If you flash an official ROM though and it overwrites it you can always just reinstall Hard SPL again and keep flashing. I hope this makes sense.
As for the files you need to flash a new ROM, they're usually included with the ROM. If they're not then just let me know and I'll upload them for you.

Good that you asked before damaging your (expensive) device...
Every Flash version comes with a RUU (Rom Update Utility) you just run that proggy and it does the rest.
To make it easier, look for a rom that states it's G4 safe (no IPL/SPL included), so you don't have to mess around with the inner files. If you want to, begin your tests with the TNT series, the latest build, stated in my sig is G4 safe, after that you'll be able to know the initial procedure.
Good Luck.

Thanks for the info.
Do I execute the ruu from Windows XP or from the SD card ont he device?
Why am I have a hard time searching for and finding TNT 5.2.1921 TouchFlo ROM?

The rom update utlity gives me an error when I try to update. Should I try to do all this from the sd card?

Well, I am plugging along. I rebooted after an error 300 came up on the rom utility. Any suggestions for me?

I found this thread, back in business, thanks for your help guys.
I guess my only unanswered question is...if I use the HTC ATT exe from htc.com will it kill the hardSPL and restore the computer back to normal?

If you have ROM on your desktop, Connect your phone to your computer via USB, open up Activesync, uncheck the check box in settings that allows USB connections. Make sure you have at least 50% battery, then put your phone into bootloader mode. (soft reset while holding down the camera button- keep holding the button for 5 sec.) a tri-color RGB screen should come up. This is boot loader mode. Then run the rom update utility program, and everything is automatic from there on. once it is done flashing the phone will restart itself.

Try it and find out. I'd kind of like to know the answer to that one too, although my phones a G3 and already CID unlocked anyway. You can always reinstall Hard SPL over again if it does.

So this worked out well for me overall. Installing HardSPL to my G4, and then using a correct bootloader with the right ROM (to review).
I am having one issue.
I have the OEM ROM, however the RUU gives me an error. Is there a documented way to restore the phone to an original status? Is it even necessary?
I ask due to problems since my upgrade to the TNT rom. I am noticing a lot of missed calls and people have complained. Is this an issue with the 8125 and the particular ROM?
I don't know what to ask, or how to search for this. Thanks for any input you can offer.
Otherwise the TNT rom is awesome. I do miss the voice dialing though. Thats another search.

Actually, that's usually an issue with your radio version. Try using either version 2.19 or farias 2.69 and see if that fixes your problem. You should be able to find both of them in the wiki and you may want to try both of them and see which one gives you the better reception because sometime one will work much better than the other for you depending on your location.
By the way, you don't have to be CID unlocked or have hardspl installed to update your radio so you shouldn't have an issue with the RUU giving you an error. If you do, let me know and I'll upload a different RUU for you to try.

So the Rom is broken up into major parts. Those parts must ineract with one another, so that would be why my radio version may be at cause?

Yep. The ROM can contain the IPL, SPL, OS, Splash Screens, GSM (the radio), and extended ROM, any of which can be changed or upgraded individually without affecting the other parts of the ROM (for all intents and purposes anyway). That means you can change your radio version without it deleting all of your settings or your installed apps in your OS, etc etc.
Since you still upgrade each individual part using a RUU that is able to update any of the parts you still get a warning when you run it that it will delete all of your files, but as long as the update that you're running doesn't include a new OS you can ignore those warnings.

I decided to back out of the entire upgrade and move back to WM5 Official Cingular HTC ROM. I am stoked that I now know the full process of taking a G4 through hardSPL, ROM updates and restoral.
I was too scared to try any radio updates or fixes. Maybe when I upgrade phones I will come back to playing with the 8125 but for now, I just need a good functioning phone for work.
Do these Cingular radio fix cabs apply to a standard phone or only to upgraded ones?

Quick question about HARD SPL

My Kaiser just arrived in the mail, and it came preloaded with DCS 1.7 rom. Since this ROM has already been loaded, I assume the the CID is already unlocked and HARD SPL has already been run once.
So does this mean I don't have to run it again to flash to Dutty's latest rom? Thanks.

not a good assumption, as there are other ways of flashing without hardspl. just put the device in bootloader and see if it says.....something with olipof in it. if that's the case the case then you have hardspl

And if I have HARD SPL, then I just go ahead and flash the Dutty ROM?

Thanks. I read through a lot of that stuff already.
I just checked and HARD SPL is already on the phone. So now it's safe to flash Dutty's rom?

Soounds like you have your answer
Well, it sounds like you've checked so if you're sure, flash away. Although, if you haven't already, I'd do a id10t check first to be doubly sure (i.e. press the camera button+Power button+soft reset) and verify you have Hardspl installed otherwise you run the risk of brickin your phone.

it doesnt hurt to do it again? or am i wrong? its just to be on the safe side

Did i brick it ?

OK i think i ****ed up bigtime.
I was on HSPL, and at first i flashed a stock rom.
After that i flashed DUtty's rom and it went ok.
It booted up with green screen problem and loads of locks and really really slow. After that i tried to use uspl but i was getting connection problems. After that i thought i should go to 1.15 stock spl and so i flashed that one, in order to use uspl. But the problems still persist, and now i cant revert back to a previous cooked rom.
Any suggestions ?

Use Manually Bootloader
Go back to stock spl, first flash stock rom, use sspl manual turn olinex and flash stock spl and then u can hspl again.
Hope it solves the prob. Just take a look at my Grafik Problem thread!

Hi,
Why, Windows 7 has the same drivers like Vista???
Can You express more crearly?

i flashed on Win 7 (build 7077)... i had to roll back the HTC USB Sync driver as explained in many threads about flashing the latest HD ROM v 1.56. i think some of our fellow members are not following all the steps to flash with the new ROM/SPL.

A message to all flashers:
Read the instructions thorougly. If you cannot say that you understand 100 % of what the instructions tells you, read them again or do some research.
After following these steps you will almost certainly have a much better experience with custom ROMs.

i tried reverting the drivers but it is simply not working. i am thorough and i do read the details.

I had no problems with the drivers. I just followed the correct procedures mentioned in the wiki and post#6 of Duttys v2.8 rom
Have you tried rebooting pc afterwards and pressing F8 as per the instructions to help load them?

i flash on windows 7 7068 almost 10+ times already with no issue , using custom ruu.

The instructions for all the different flashing methods are a big mess if you ask me.
There is no red thread, they all just blend together in a big mess and leave out answeres to simple questions that would clearify stuff for newbies.
The more i read the long pages of instructions the more confused i get.

I agree, they can be confusing, but once you have mastered it, you'll wonder what the problem was!
What exactly are you confused with? What steps have you taken? Where are you now in the process?

Don't worry about the phone it will be ok.
The steps are as follow:
1). Flash hardspl
2). Flash a stockrom
3). Flash USPL 2.5
4). With USPL on your phone flash to Dutty
To revert back to previous roms:
1). Flash hardspl
2). Flash your previous rom.
Grtz,

Im fine, thanx, I have flashed my phone twice without big problems.
But the second time I got really confused when i tried to really understand it and followed the instructions step by step, it just sent me in a loop between all the different pages.
A simple question and a simple answere in the ROM-thread solved my confusion then, and now I just ignore the ramblings in the instruction pages.

I have a question about this. As my HD was replaced (warranty) I don't know which version I have (O2 or HTC). My first HD was a O2 branded with 1.14.207 ROM, the replaced one (from the same supplier) came with the 1.14.407 ROM which is the official German HTC ROM. I've just tried to download the newly released ROM by HTC, but the site states that the new ROM is not available for my device (but I could at least register the device). Could be that this is because it's an O2 device or probably because the new ROM wasn't yet released in German?
So is it really important to flash exactly the stock ROM (as the CID has to fit) or is it okay - like Laurentius said - to flash any stock ROM? Don't wanna brick my device when upgrading to 1.54/1.56...btw...why one has to go to a stock ROM when upgrading to 1.5x afterwards? Is there a difference when upgrading from 1.14 to 1.5x instead of 1.19 to 1.5x? I didn't get it yet...
Thanks in advance,

Any stock rom should do it as Laurentius said

A lot of confusion has come about from these newer cooked 1.56 roms so I wrote a guide. If you still have confusion please read the guide in my signature
Windows 7 is also most definitely not an issue. Several of us here are using it successfully.

Please help

I really am going crazy with this rom flashing stuff. I have read the wiki for 2 days.
I understand I need to CID unlock my phone before I can apply cooked roms. But after countless searches I cant find clear info on how to CID unlock my phone.
This really is a last resort, I have been rading for 2 days with no certainty of what to do next.

USPL and HSPL do this for you so you are able to flash a rom or radio. Read this page from wiki. It'll help you understand
Follow cRaCKwHoRe's guide on how to flash (can be found in my signature). If you intend to do a lot of flashing I'd flash HSPL as its permanent whilst USPL is temporary and you'd need to re-use it before every flash to new rom or radio
Latest HSPL can also be found in my signature

Ah excellent thank you so much.
So can I flash straight to the newest 1.56 rom from my current version which is 1.19.61.1WWE on orange?
Or is there a stage in between I would have to do.
Thanks again.

Flashing from one HTC stock rom to another you don't need to use USPL or HSPL. But going to a cooked rom you do.
Answer to your query is it depends on route you take. If you go down the USPL route you'll need to follow cRaCKwHoRe's guide. Would take to long to explain and he as already done a very good tutorial on the subject. If you go down HSPL route, all you need to do is flash latest HSPL then 1.56 rom

That clears everything up. one last thing, which rom would you reccomend? I like the look of the enwer roms with WM6.
Thanks again much appreciated.

I'm currently testing Dutty's V3.4. His V3.3 is already released but I'd wait for the new release hopefully in a few days. Both are based on WM6.1. Alternatively their is so many good roms out there. I'd also recommend Davideuck, EnergyROM & L26_THDV2.2 (Laurentius26). All very good roms by very good cooks. Best thing would be to try each of them and make your own opinion

thanks again mate, you are a legend, Ill post tonight to let you know how it went.

There are a few forms of unlocking but the bottom line is that you need to bypass the checking which is done in the flash process.
One way is permanat as done once no issues anymore - HSPL
Another is as and when you need - USPL.
Wiki has a walk through that needs to be upated but I thought still was useable.
Flash the new 1.56 shipped rom and then move on to cooked roms. (will help you by pass the greenscreen issue)

Sorry to hijack your thread futurama but I am having the same problem. Could you let me know how you did it

Thanks HDuser. Not sure if you know where I`m up to but originally I flashed my Orange 1.19.61.1 ROM with USPL and then flashed Duttys 2.7 1.56 based ROM which has given me the green screen problem. An earlier poster suggested I flash Olinex HSPL 1.54 to cure the problem. The problem I am having now is the phone refuses to sync with the PC. I have tried Vista and XP, the PC does not hibernate or sleep or anything, the phone is set to not switch off. It will usually sync on first connection but after a few seconds it will disconnect and therefore HSPL is reporting as being disconnected.
I have tried the earlier HSPL and HSPL 1.56 (as the ROM in bootloader screen is reported as being 1.56 and SPL is 1.14). I feel I`m going round in circles and its only a matter of time before I brick the phone.
I have read and re-read the wikis but I am now just getting more and more confused.

davemazo
Look the best way to approach any problem is to go back to the roots.
Flash a stock rom, find your own stock rom and refalsh it, then take it from there.
Your post is missleading and I have no idea were to sart. One issue is your PC ist does not Hibanate, not or go into sleep mode, at the saem time you are saying that you can't sync. Sounds like you have other problems and those other problems are making you have problems with your device.

Thanks HDuser. Sorry for confusing you, but I am now totally confused myself, Basically though the phone does not sync with the PC, I have tried 2 PC`s, with Vista and XP.
But back to your point about flashing stock ROM, I have tried a link in the wiki to download the one I need which is Orange 1.19.61.1 but the link seems to be broken and I don`t know where else I can get it. It doesn`t seem to be on the Orange website or HTC.

There is a part on the black stone wiki that mentions I need to CID unlock my phone. It says you need to do this before you can flash roms, I felt it wasn't clear that, all I needed to do was flash HSPL in order to allow me to put new roms on.
This is what I did.
1:Flashed HSPL olinex 1.14.
2:Flashed HSPL Olinex1.56
3:Flashed MIRI WM6.5 10.0WWE
only part I had trouble with, my phone wouldnt let me flash the HSPL at first, I had to use a manual thing that you launch on the device the it lets you flash the HSPL.

It sounds as if you have it sorted now and everything working. As HDUser stated previously HSPL & USPL allows you to bypass the CID lock to enable you to flash new roms

Only thing I need clearing up, I can change my SPL back to the original version cant it?
Just incase anything goes tits up and I need to send it back

flashing to a new rom

Hi all i am new to this got my first HTC Touch HD today
looking at the roms theres a few i like just got a few questions.
what is the best to use HSPL or USPL?
will flashing a new rom mess up my sim lock?
When it says donate whast the normal to donate? dont want to give to little
thanks about it
Thanks
Jonathan Hemmings

HSPL sits in ur rom permanently whereas USPL opens the loop once. That means flashing each time u need to use USPL
U need to read this guide fully to understand and make ur choice
http://forum.xda-developers.com/showthread.php?t=505377
People donate as low as US$ 5 whereas donating US$ 10 is a good amount to start with. Flash different rom's and make ur choice which author u like more. Then u can donate a higher amount if u like that author's creation. I am a big fan of Energy's pheonix rom.
Regarding SIM lock. Flashing rom doesnt mess with ur SIM lock or unlock feature and if ur sim is locked u can open it with olipro's tool. Try searching it in the forum.
It all depends on u what flashing method u choose, how much u donate and which rom meets ur needs....
Welcome to XDA and have a great time here.
BEWARE: Flashing ur phones makes ur phone look much cooler and sexier and u will madly fall in love with ur Touch HD once u find ur perfect rom
HAVE A GREAT STAY....

Thanks for the info mate
one thing i cant get my head round is the USPL and HSPL it say that HSPL is permanent but then it says once you have done it you can flash as ment times as you like ?? i am a little confused.
with the USPL if the battery dies or you take your battery out will it lose the rom?
Thanks
Jonathan Hemmings

also is there a way of making a copy of the rom that is on my phone now just incase i did not get on with any of them and i wanted to go back to this one?
thanks again

HSPL is one written to the handset. USPL isn't written to the handset, the files are sent to the handset when used and it loads another SPL on top of the existing one which is lost when the handset is rebooted (i.e. when the ROM has been installed).
I personally use USPL so I can keep the stock SPL as installed by HTC. Some prefer the HSPL as they don't have to use USPL everytime they want to flash.
I'd probably start with USPL and if you find you flash more often, change to HSPL. Apparently though, HSPL provides more protection against a bad flash - unsure what it does though as I've never used it
It doesn't matter what SPL you use though, once a ROM is flashed to the phone, it stays there until you flash another.

I'm unsure of any way to backup an existing ROM. I'd take a look on HTC's website as they may have an updated stock ROM available for download. I keep that one as my stock ROM to revert to after a couple of custom ROM flashes.

Thanks for the info mate
one thing i cant get my head round is the USPL and HSPL it say that HSPL is permanent but then it says once you have done it you can flash as ment times as you like ?? i am a little confused.
with the USPL if the battery dies or you take your battery out will it lose the rom?
Thanks

Factory SPL is preventing you to flash any ROM made for another region or another language. Sometimes there are specific ROMs, made by HTC for certain providers, and SPL takes care to allow you only to flash an official upgrade for the same provider or the same region.
If you wish to flash a cooked ROM, you need to circumvent this protection in the SPL.
USPL makes a loophole in your existing SPL and it will allow flashing (now I see jonifen has explained it better). However, that loophole will disappear after the hard reset. Whenever you decide to flash another ROM, yo'll have to repeat USPL. The advantage is that you keep your official SPL.
HSPL is completely replacing your SPL with a new one, and the new one is slightly changed by OliNex: it always let you flash any ROM you want.
Hard reset will not affect it, as hard resets do not replace or wipe the ROM, SPL or the radio, they only wipe all your data and all 3rd party applications installed by you.

Thanks for all the info i am now flashing i have gone for HSPL as my phone is out of warranty + its lots easier + more stable from what i have read on here.
Thanks again for all your help
