Question: Proper order for ROM downgrading? - Tilt, TyTN II, MDA Vario III Windows Mobile ROM De

I wanted to downgrade my ROM to 6.0 to SIM-unlock my phone as well as to try and troubleshoot some problems I am having. I searched the forum but I cannot find a clear answer. Apologies for duplicating a question if it exists someplace else.
Right now I am on HardSPL 3.29 on a Tilt with dutty's 6.1 and Radio 1.65.21.18. Once I find a ROM to downgrade to, is this the proper order:
1) Install HardSPL 1.x
2) Install 6.0 ROM
3) Install Radio for 6.0 (or specific radio for unlocking)
Thanks...

Take a look at this. Makes it VERY easy to do a SIM-unlock.
http://forum.xda-developers.com/showthread.php?t=375583

I was looking at just the SIM-unlock as I do not need the CID change. I still thought that it was a requirement to downgrade to 6.0 first.
Still, even if Olipof's program doesn't require a downgrade, I still wanted to troubleshoot the issues I am having and wanted to run 6.0.
Kojak

The process you outline is fine. Just make sure to use JumpSPL to downgrade the SPL.
Good luck.

Just an update for those following the thread or who come upon it later...
I downgraded to SPL 1.x, then applied Dutty's TouchDual v4 ROM. The phone booted up, got to customization and ran through it successfully. However, after resetting, it hung on boot up. Even if I bypassed the customization the phone still hung. This prevents you from flashing the radio, which is the solution to this problem, since that ROM, and probably others, freeze when trying to access an incompatible radio.
The only way out of it was to flash the radio, but since the phone hangs on boot, you cannot do this via Activesync. The only way is with the MicroSD card. It's super easy - so long as you have a card reader and adapter.
So moral of the story - it pays to be prepared. If you are going to downgrade, make sure you have a card reader handy.

a need to know
so if test out this rom how can i get the bootloader to 1.04 so i can put the old rom back to the phone do the cid unlocker "did i get that right? work on this type of phone?
llmo128, if you are flashing to an apache, you only need to put it into bootloader mode to flash custom roms with the MaUpgradeNoID utility. You should be able to go back to an official upgrade from a carrier by just running their packaged installers.
As far as getting this on other devices, I do not know. I have done the cid unlock on a wizard, but this rom will not function on a wizard.

Flash - What Went Wrong?

I've always fancied flashing my Kaiser (V1615) with a new ROM, but was always nervous because I wasn't sure of the process and didn't want to risk bricking the phone as well as all the effort needed to get everything back on it I needed. Well, a few days ago my old Kaiser met the floor and an untimely end. So I decided to take the risk and put a new ROM on it and decided on the latest Dutty WM6.1 ROM.
I read all about flashing on here and made as much sense of it as I could. Thing is, I'm very technical in general, but not very familiar with Windows Mobile or flashing. I found there was lots to read, but it was all written with an assumed level of knowledge and understanding of terminology. As a result I found it quite hard to understand. I took the plunge anyway and started, but things didn't work out as expected and I didn't understand why.
I'm not trying to be critical of all the work a lot of people have put into the documentation that is available online, it's just that when I originally approached this with zero flashing experience I found it difficult and confusing to understand. What I really needed was a concise and basic introduction to flashing. I've now been through the process and after re-reading the documentation it makes a lot more sense.
I worked out you need to run something called HardSPL before you could flash a new ROM. I'm still not sure what HardSPL does apart from CID unlock the device, but what does CID unlock mean?
I ran HardSPL v1 and it started ok, but then I ended up with a white screen. At this point I already wished I hadn't started, but no going back now. Is it known why some phones white screen? Turns out it's a common problem, so followed the instructions to recover. All was well again, but still with the original ROM.
I thought I'd be brave and stuck with it and this time tried JumpSPL1.56-KAIS instead of HardSPL as recommended on one of the tutorials. This went better and I ended up with the Tri-Color screen. I plugged my USB cable in and USB showed on screen.
Next step I thought was to flash a ROM onto the device. I ran the Dutty updater on my PC and all started ok, but when the update got to 18% I received a communication error. I tried to recover using the updater, but the same thing happened. At this point the phone wouldn't boot, so I was more than a little worried and wishing I hadn't started!
Found something that described several options for recovering from this problem. I decided to try and flash the device back to the original ROM from Vodafone. When I eventually found that ROM I ran JumpSPL again, got to the Tri-Color screen and ran the updater. This time the update completed successfully and the phone rebooted and was all working again.
I decided to leave the device as it was and started customising it myself. I'd still love to put a cooked ROM on there, especially if it helps with performance, but after the experience above I'm not very confident.
Can anyone tell me where or what went wrong? I'm going to get my old Kaiser repaired and want to try again on that phone.
My flashing routene (not ideal but it works for me)
1) run the first part of the Kaiser SIM/CID Unlocker & Changer
2) after device reboots, hold camera button and restart to check SPL
3) Flash rom/radio of choice
4) Follow HardSPL v3.07, v3.28, v3.29 and v3.56 by JockyW 's second guide "If you have problems with the above process, try this:" and flash my 3.XX SPL of choice.

Wow, I need a cuppa now
I'll go through 1 at a time... (and Sam has answered some questions already)
-CID unlock means that when the phone is loading a new device into the ROM the Carrier ID check is removed, each Mobile phone carrier has a different CID in thier OS ROMs. Unlocked means you can flash a OS ROM from any carrier or a cooked OS ROM from this site.
-The Jump SPL should only be used for replacing the SPL. Do not flash anything other than SPL's when at the Jump SPL (or SSPL). OS and Radio ROMs should be flashed from either in Windows Or By Manually Entering the Bootloaders. More info on SPL's is here: http://wiki.xda-developers.com/index.php?pagename=SPL Questions?

Thanks for the advice, but this is what I normally encounter when I read something on here, which is advice which no doubt makes perfect sense to the author or others experienced in flashing, but usually raises more questions than it answers in my head.
For example;
1) run the first part of the Kaiser SIM/CID Unlocker & Changer

Ok. I get this assuming you mean the device will reboot automatically and I restart it to check the SPL version that gets shown on the boot screen, but why do I need to do this?
3) Flash rom/radio of choice

So at this point I can simply plug my device into my PC and run the ROM updater I've downloaded. Working out what rom/radio version to download is a minefield in its own right.

I thought HardSPL needed to be run before I flashed? Also, why the different versions? Which one do I choose?
BTW, not trying to moan about everything, just posting my experiences to find out where I went wrong, but also highlight some issues hopefully other flashing newbies can relate to and authors of tutorials can draw some useful feedback from.
Only one question, do I need to CID Unlock before using Jump and HardSpl or, the Hardspl does the Supercid ?
I'm not referring about SIM since I don't care, for now
With WM6.1 - Oficiall HTC ROM
Thanks
Thanks for that one dave, on reflection i kinda missed the whole point of the thread, and as for the majority of the stuff you posted i didnt undertand that to begin with.
Also, DaveTME, if you are wanting to flash a custom rom to youre kaiser. from my experiance and from the number of times ive seen this happen. i advise against asking for reccomendations(sp?) (not saying you will but its worth saying) try a few roms out and decide from there.
Also another thing to note. if you flash to WM6.1 remember to use a 3.xx spl otherwise you'll encounter a few problems with youre device.

download the Kaiser unlocker and run the first stage of it, the program is in the linked thread.

No, after the device reboots, youre given youre Rom, Protocol and Radio. if you hold the camera button and reset you'll get youre SPL displayed, youre looking for 1.01 olinex to be shown
So at this point I can simply plug my device into my PC and run the ROM updater I've downloaded. Working out what rom/radio version to download is a minefield in its own right.
Click to expand...

1) Yes, just run the RUU with youre chosen rom and thats it
2) its not a minefield, just make a decision on what rom you like and flash it. theres nothing to stop you flashing another one.

The 1.01 SPL will allow you to flash a cutom rom. following that you need a 3.xx SPL as they are designed for windows mobile 6.1. as for yure decision. i use 3.29, yet other users have had better sucess with 3.56. Most rom chefs will say which SPL they reccomend anyway with their rom.

Tell me if I got this right (my explanation for noobs about ROM flashing)

Some guy on another forum was asking me for help on customizing an AT&T Tilt (HTC Kaiser to you international folks) he just bought. This was my explanation. If it's not too much trouble, I would like for you experts to peruse it and tell me if it I got it all right.
Here is what I wrote to him:
Everything about customizing it can be found here: http://forum.xda-developers.com/forumdisplay.php?f=378
If you want to flash a ROM, start by reading this post: http://forum.xda-developers.com/showthread.php?t=433835
I'll spell out the process a little bit, though, so it's easier to grasp. First and foremost, there is a ROM. The ROM is basically an amalgam of other components. The three important ones are: SPL (I'll get to that), OS (yes, operating system), and Radio (tells your phone how to connect to networks). Now, when you first turn on your phone, there is a thing called an IPL (initial program loader) that checks to see that everything is in order on the hardware end (if you know computers, think of it as POST). After that, it passes control of the phone to the SPL (secondary program loader), which verifies that your ROM and OS is not corrupted, accepts triggers for other commands, and then loads and passes control of the machine to the OS.
The key is to tell the SPL that your ROM is not corrupted and that it is OK to load it. Obviously a legitimate ROM by AT&T or HTC will do the trick, but suppose you want one of the fancy ROMs out there, you'll have to trick the SPL a bit. There are two ways of doing this: (1) HardSPL and (2) SoftSPL.
A HardSPL is a "permanent" solution. It replaces your SPL; it's basically a cracked version of your SPL that removes the integrity checks that would normally be done. It's referred to as a permanent solution because it will not undo itself, nor can it be undone even if you flash a stock ROM (by AT&T or HTC), but there are ways of reverting back to the original SPL if necessary (I made this package that contains everything necessary, including instructions, on how to do this).
A SoftSPL (AKA SSPL, USPL - UpdateSPL, JSPL - JumpSPL ... all the same thing as far as I know) is a temporary solution that is basically done for the purpose of loading HardSPLs, but you can flash ROMs with it as well (this is generally not recommended, though). It's a standalone EXE file that you will load onto your phone. When executed, it will unload your OS, and load up a cracked SPL. This will allow you to flash an illegitimate ROM to your phone, namely a ROM that replaces your SPL with a cracked one.
After that, you're golden. You can SIM unlock your phone (if that hasn't been done already) if you want. You can SuperCID it (CID is Country ID; a SuperCID is tantamount to using a "region 0" DVD player), but that's not necessary for you, personally; only useful if you sell to someone overseas. You can start flashing custom ROMs that are pieced together by the fine folks at that forum I linked above.
In short:
1. Transfer SoftSPL to phone.
2. Run SoftSPL.
3. Flash HardSPL.
4. Flash custom ROM.​
Thoughts?
you could have given a simple answer
read the wiki and Search

jk lol, you listed the step very well
Its good to see you did so research already i just have a few "corrections" per say......
The spl just tells the phone that if there is a bad flash it needs to revert to the boot loader (basically what you said, but i made it a little simpler to understand for those reading)
jump spl is if you have a problem (such as the kaiser white screen issue) to jump start the spl flash
soft spl only protects the until you flash a new rom (kind of like a disposable hard spl)
Hard spl is permanent as stated
use this link to find out how to flash your first rom.
http://forum.xda-developers.com/showthread.php?t=433835
(this is the same as the second link you provided)
the link other link you provided is only for the kaiser rom section (therefore not everything there will work for every phone)
"In short" ,
You really only need to hard spl before flashing a rom (unless you prefer soft spl, or have problems flashing and need jump spl)

[Q] wrong rom update, what now?

Hello everyone.
Yesterday I saw that there was a new update of my favourite rom EnergyRom. So today I downloaded it, installed it, everything went well. Until I restarted my Raphael ( raph300 btw). It kept stucking on the bootscreen.. even after I installed the rom again it still stucked at bootscreen. So I began trying to fix it with installing my hardSPL again, that didn't work either, still no further than my bootscreen.. after a while I decided to downgrade my spl to my stock-spl. that went well but still stuck on bootscreen. So I tried to install my stock-rom from my provider: (t-mobile netherlands). But then the Rom updater stuck at 0% and I received the well-known [262] error. Suddenly I saw that I stupidly accidentally installed the cdma version of EnergyRom instead of the one I needed: GSM. That explained why it wouldn't boot in the first place. Now I tried to install the olinex hardspl, but the updater stopped everytime with the 262 error. I connected my device to another computer with windows XP, but there I saw that the computer recognized it as a CDMA device.
I know it is a stupid mistake, but is there anybody who knows what I could try? I also tried to hard-reset it, but that wouldn't help either. Any help would SO be appreciated

Thanx, but how can I use this in combination with my problem?
As I remember 2 years ago,HardSPL is somehow depended on RadioROM. Maybe the ROM influenced the Radio with HardSPL,so try to reflash HardSPL again and Radio. Or it works absolutely not?

No, I can't update any ROM. So now i'm stuck with my stock SPL, therefore I wanted to Hard SPL my device, but that didn't work and since then I haven't been able to update any ROM.. would flashing on a different PC help maybe? now I am on a Win7 Pc but maybe it will work in WinXP..
It is also not a bad idea to try different PC with XP to flash. I remember apx.1 month ago I tried to update HTC Trinity with WM6.5 ROM and it keeps failed with some errormessage(nowadays I can't remember which,but the syndroms was similar). Then I considered it as "bricked",until I tried another PC and everything wents correctly and the phone is in its productivity again. Yes,tfirst PC was company notebook with lot of safety kind of software(firewall,this,that,etc...) and the second one was my private laptop at home,just equipeed with regular antivirus software,all updates disabled(instead of AV).
Btw,what about trying to flash official ROM,while you are with stockSPL? Maybe it helps you to startup again the device and then HardSPL again afterwards...

yeah, that's what I thought too. I tried that also, also tried other custom roms btw before going to the stock rom. But with the stock rom it also stuck at 0% on the update
so, today I tried to flash my rom with two different computers: one with win7 and one with winXP. didn't work either.. I read the MTTY thread and after I installed the custom driver I was able to connect trough MTTY. But what commands should I use to clear the ROM and is there any way that I can update my rom via MTTY?
search MTTY on the forums the first link has all you need to clear the rom and flash via MTTY
I think you may be screwed. You should've asked for help before you started messing with the spl. I don't understand why you thought reverting to the stock spl would be a good approach; it may well be the end of your device. What you should have done is just flashed a stock rom-that would probably have restored your device. Re-flashing hard spl is kind of pointless. The only thing that can over-write hard spl is the special 'stock spl' that olinex put together. It's not entirely stock, and I am not sure that it can be over-written by hard spl. The sole purpose of the 'return to stock spl' is so that you can flash a stock rom, then restore the spl so that you can return your device for warranty/service without being dinged for having unofficial firmware on the device. When you do this, you aren't anticipating getting the device back, so I'm not sure that hard spl can over-write it. I know there have been discussions on whether or not it can be over-written, but I'm not sure that there was ever a clear answer. Anyway, with the 'stock spl' on the device, you can't flash any cooked roms to the device. If you are very lucky, you may be able to flash a stock rom. So, my advice is to try a few stock roms.
I'm pretty sure you'll need hard spl to run mtty/task 29, so I wouldn't waste your time on that. I really doubt it works, and I'm not sure what it's going to buy you, anyway. You really need to be able to flash a rom to the device, and you can't flash a cooked rom with that spl. Maybe you can flash a stock rom, but maybe not. I'm not sure which carrier it will let you upgrade to, either.

yes I did, but the problem is that I can't access my Internal Storage, so I can't put any ROM's on that. Tonight I tried to flash a ROM via my SD card, but when I put my device in bootloader-mode it kept saying that it was 'loading...'
If the bootloader just says 'loading', then you probably need to either reformat the card to FAT32 or rename the image to RAPHIMG.nbh. Make sure you get the extension correct (not RAPHIMG.nbh.nbh).
But you're not going to flash anything with the stock spl, anyway. You need hard spl. I'm not sure you can even flash a stock rom off of the sd card-it probably needs to do it over usb.
I updated lot of smartphones already,but it was already few years ago. However I think,that SP's are flashed with MTTY. For that I needed ROM image in nbh file and with some commands you tell the PC,that it should flash it. Don't forget to disable USB connection in Activesync on XP in case MTTY will connect.

I already managed to connect my device with MTTY, the only thing I need to know is which commands I can use to flash the ROM through MTTY. It just sucks that I am not able to go to my Internal Storage, otherwise it would be much simpler I think.

Oke, thanx for your input. I tried to reset my ROM memory with mtty/task 29, but that didn't work, just like you predicted. So my next question is: 'Is there any app that can perform the task 29 without MTTY?'. I googled it, but I could only find the task 29 app for the HTC HD2.. And further, does anybody have a recovery ROM for my RAPH300? I tried the stock ROM on the XDA thread of HTC Raphael, but still got the 262 error
There's really no point in doing Task 29. The bad rom isn't what's killing you now, it's the SPL. It's going to block task 29, no matter what you try (that's one of it's jobs). You should just try to get hard spl back on the device, or try flashing every stock rom you can find. I tend to doubt that either will work, though. The only other option would be to look up the jump spl developed by PoF. I don't remember the name (search for threads started by him), but it was a universal soft spl that would temporarily CID unlock devices so you could flash custom roms. I've never used it before, and I don't know how it loads. You may not be able to load it onto your device with its current state, and it may not even be compatible with a Raphael (it's 3 or so years old), but it's probably worth at least checking out.
Edit: here's the jump spl link. I think you may have to activate it off the device.

[Q] Does updating the SPL update the Bootloader?

My Titan cannot get updates to install and it seems to be related to the Bootloader.
http://forum.xda-developers.com/showthread.php?t=1481445
http://forum.xda-developers.com/showthread.php?t=1435745
HTC Hong Kong wants me to take my Titan to their service center for servicing, which will wipe my data in the process. Since there's no way for me to backup my messages and app data, no way I'm doing that, I'll either find a way to fix this problem myself, or brick my device trying.
My Titan's About screen says its Bootloader version is "2.2.160015.3(134181)". If I get an .nbh of a newer ROM, keep only the SPL.nb and throw away everything else, and flash the new .nbh with RUU or the Goldcard method, will the Bootloader be updated to a newer version?
The SPL is the bootloader, yes.
There are ways to update the SPL without flashing the whole OS (which also wipes the phone). For my HD7, there was a "radio update" RUU download that had both the radio and SPL updates in different files. I removed the radio part, and then put the phone in download mode and ran the RUU. It downgraded my SPL from 4.5 to 3.1 (so I can now use HSPL again, if I choose to). Something similar might work for you.
Be sure you use an RUU that doesn't wipe the whole phone. You'll get a message telling you it will wipe the phone anyhow (scary) but not all of them do so; it depends on a configuration setting.

I've (accidentally) tried using the stock RUU and the HD7 RUU that doesn't wipe the phone, both couldn't flash the SPL .nbh I made, the progress bar just stuck at 0% forever.
I'm thinking of trying the goldcard flashing method, but does it accept SPL-only .nbh files? Will it wipe my data after flashing the .nbh I give it?
If it's going to wipe my data anyway, I'm going to stick to 7740 for a while until Microsoft comes with a better backup solution.
