How do I downgrade my JJ to WM05 - JASJAR, XDA Exec, MDA Pro ROM Development

Hi
I bought a O2 Exec and it has WM06 on it
I want to go back to WM05
How do I go on with that?
Thanks
Yeshai

well technically you flash it so i have heard. but dont go on my word im just telling you what i have found when I SEARCHED

If you are on O2, the easiest way is to visit the O2 xda website (http://www.my-xda.com/xdaExecSoftware.jsp) and download the software update. That will flash it back to a pretty unresponsive (but official) version of WM5. Make sure you use it in corporate mode (the PIN you need when you come the the appropriate place in the setup is 0506) otherwise it is extremely slow.
Alternatively, you could try downloading one of the AKU 3.3 or AKU 3.5 ROMs. I always liked Helmi's. Search the forums to find them.
Also - make sure you read the relevant advice in the wiki and in the forums on upgrading lest you end up with a brick.
Good luck

Problem is not backstepping, but finding, after so long, the roms you might read about and would like to try!

Thank you all
I was too afraid to try it like that.
It does seem strait forward.
And I have a full backup of XDA old FTP site

Some basic info for a new member

I was directed to this website from somewhere, with only the knowledge that my phone is a 'Universal'. I currently want to upgrade its OS to WM6, but i have no idea how or what actual version to put on. Theres an overwhelming amount of ROM's and i have no idea which one to use, or if they will even work with my phone let alone my provider.
Can someone please help me out?

You're in the right place, just start reading at the wiki and then do some foot work through the posts. you'll get there in the end.

Upgrading my X51v to WM6 but with the possibility to get back to WM5

Hello everyone,
i've posted it on the Upgrading, Modifying and Unlocking section but maybe it is more indicated to be here... I'm new here...
sorry for posting this noob questions here, I see that you all are discussing software development and stuff, but it is the only place I've found to ask about it.
My situation: I have a Dell Axim X51v wich is still on warranty and CompleteCare (until march 2009!). It has a WM5 A04 Portuguese Rom wich is very unstable and quite lame (I don't like the system in portuguese!) and I'm looking forward to use the WM6 Football Rom, that everywhere I read says its very nice.
The fact is: If I had to call Dell for support, I'll need to give them the Ax with the WM5 Portuguese rom. I really consider this since the device isn't brand new and if something happens I don't want to loose it.
So, what I need to know is how (and if it is possible of course) to get the image of my Ax as it is now, to store in a safe copy on my pc or a cd, upgrade to Football's WM6 (wich version, btw? I see that there are RTM and Preview A06 on the thread) and then eventually get it back to my current rom, if I need to use the warranty. I know that the upgrade part is well documented around the internet, but the downgrade to the same or similar system is the major doubt.
I'll be grateful for any help. I'm new to all this and there are lots of knowledge around. Never had any experience flashing, just upgraded my ROM one time with the official procedure from HP, on my old Ipaq.
Thanks!!
anyone here?
Hi,
I work as a support analyst at Dell headquarters.
I wanted to let you know that the A04 ROM for the Portuguese version of WMV 5.0 can be downloaded from our website. You can find it here:
http://support.dell.com/support/downloads/download.aspx?c=us&cs=04&l=en&s=bsd&releaseid=R131773&SystemID=PDA_AXIM_X51&servicetag=&os=PPM&osl=BP&deviceid=7638&devlib=0&typecnt=0&vercnt=4&catid=-1&impid=-1&formatcnt=1&libid=7&fileid=174977
That should help out. Let me know if you have any problems.

This is John again. After posting that link, I realized that the link was for the x51 ROM. Do NOT download that link!
The link to the x51v is here instead:

Sorry for the confusion!

Thanks John!
If I run this brazilian WM5 rom "update" application of version A04, it will install on my X51v even if it has installed on it a more recent english WM6 rom?
If so, I don't have much to lose testing the hacked rom... of course, there is the risk of bricking it if I make the wrong procedure, but I guess that is well documented around here, right?
thanks again!
You should be able to flash the ROM, even if a more recent version is installed. You shouldn't be bricking your Axim by doing any of this.
Glad I could help!
all right!
I shall try the alternative roms then!
but, I am downloading this rom from dell:
http://support.dell.com/support/dow...-1&impid=-1&formatcnt=1&libid=7&fileid=174968
it seems to be the right one since mine is X51v 624 mhz.

Can I use 6.1 ROMs on my Kaiser?

Hi,
Can anyone tell me if I can use the 6.1 ROMs on my Kaiser or am I limited to 6.0 ROMs?
I tried to download the Windows Mobile 6.1 upgrade from HTC but when I enter my Serial No. it says its unsuitable for my phone.
I bought it on ebay and its full of rubbish and seems heavily tampered and has lots of querky things going on - so I thought I would just flash it with one of your ROMs. I don't want to 'brick' it if 6.1 is incompatible. I have spent days reading the (astoundingly detailed) FAQ's but, maybe 'cos I'm dumb and don't understand the difference between ROM and OS, I'm worried I will trash the phone if HTC say its incompatible.
I'm rambling now because what I don't really know is whether A ROM includes OS or sits on top of OS.
Regards,
JN
You can, of course, use 6.1 roms on your kaiser. I suggest you just go to the kaiser section, read a bit, and find yourself a nice ROM.. the kaiser section is flooded with ROMs.. and good ones
Thanks for replying. I found several posts today from people who have trouble with screen touch alignment and wondered if there was a hardware incompatibility with some Kaiser's and WM 6.1. Also, I found the answer to my question about ROMs and OS in Q1 of the Kaiser ROM Flashing FAQ which I had already read but obviously not taken in.
I shall give one a try then.
Many thanks,
I'd suggest giving a few.. until you get it right
LOL
Ok then. What are the chances of totalling the phone? Mind You, I've got to the point where if I junk it I won't care too much. So I shall just have some fun.
Thanks for the reassurance and advice.
You should be able to hard reset if everything fails...which should save you in the worst case situation... I beleive though from reading up on it if you unlock your phone with HARDSPL it is supposed to stop you from being able to brick your phone
First of all, try try a few roms without spling more than once, find the hardspl guide for kaiser in the kaiser forum and hardspl it so you can flash as many roms as you like.
afterwards, just start flashing roms. bricking a device isn't that common if you do things properly. make sure all roms you flash are meant for kaiser..
Thanks again for the help and advice, which I have followed - I've applied HARDSPL as recommended. I've only had a chance to apply one ROM so far (AtheneOS WWE) which looks fantastic IMHO but I have what seems like a radio problem as I have no sound. So I shall have a go now at different radios I suppose? That's what most of the replies to posts seem to suggest for lack of sound after flashing. Its easier than I thought this lark - I can see this may be habit forming though
Great stuff you guys .

Another Happy (rom) Flasher!
lol. go ahead and enjoy flashing.

need to upgrade my cingular 8125

I have tried and tried so many times to upgrade with things from this site, i have had no luck what so ever, i have not given up i love a challenge. I go to get the rom and i use xp doesnt seem to like vista to much, it finds the phone and then i hit next and then it goes to flash the phone and it looses the connection or something and it says not able to find phone blah blah, i would love to have 6.1 or 6.5 or i hear 6.5 is amazing, is there anyone here that can give me the exact link and or file, and directions on how to flash 6.1 or 6.5 i am about to loose my mind and would love some help, my motorola q died of bad death 5 feet into a pool, and i miss my windows so if you can help me and not confuse me contact me at [email protected] it would be much helpful and make me very happy.
EVERYBODY NEW: Please read the stickies. Your answers are there. Really. Read them. You'll see! Look especially hard at the How to flash a new ROM to your wizard sticky. Read a LOT before you ever start flashing, or you'll have an expensive brick instead of a cool phone. Don't be the guy who screams "PLEASE HELP" because he flashed first, and read second.

Use XP, use Activesync 4.5. Do NOT use Vista under any circumstances.
Make DAMN sure you've unlocked your phone's CID. There are different procedures for different models of Wizard. Do the wrong one, you will destroy your phone.
Use Mun's RUU if the cook's RUU doesn't work with your phone.
Only the Oldest WM6 ROMs will include IPL/SPL, which may kill your phone if it's a G4. Newer ROMs are almost always safe. Cook will tell you in the ROM's description.
Your Wizard is not any more waterproof than your Q was. Keep it away from the pool.
Read, search, learn.

Can't unlock the SPL??

Hello All,
I do a lot of reading and follow along pretty good so far. I have done the unlock (I think I did) I was able to use other carrier's chip while travel over sea. So I figure that I have unlocked my Treo 750. I was also do the up grade to WM6.1 without any problems.. But now I keep reading the SPL and the IPL posts. So I took a look at my Treo 750, and it show IPL 0.20 and the SPL 0.24.0000. I try everything that was offered in the forum to unlock and reset and all the tricks and tips. Nothing works. The best I got was using the Cheeunlock and it only goes to 7% on my Treo and reset really quick. I seem to remember upgrade once to the WM6.5 using one of the forum members suggestion, but for the life of me I can't do it any more. I went back to the WM6.1 in matter of facts using the suggested method by a forum member. That is where I am at now. The question that I have is that, if I was able to upgrade to WM6.1 and using other carrier's chip. Am I unlock? Or am I just thinking that I am? , also why can I change the SPL and the IPL value? Thanks in advance for all the help, and sorry for such a long post.
O.K. so many views but no reply, but it is all in the name of testing. I guess after I have post this question and recevied no reply, I did some more reading and going throught he instructions over and over again and again, can never pass the #11 step to see the blue screen for upgrade. But I finally did it. The thing I did was to follow the upgrade and unbranded post here till the #11 step and the only change that I made was to included the *.nbh file (which ever one you want to put in.) in the tempche folder in your computer, and it took the upgrade and unlock the phone, change the hard spl and all that good stuff just like the instruction said. I guess you can called that #11a in the instructions. After I did all that I can do the upgrade to the WM6.5 without any problems, and revert back to the WM6.1 without a hitch. So if you guys are having problems doing the unbranded or upgrade try to put the *.nbh file in the tempche, instead of in your sd card. Good luck I am waiting now for the new 23XXXX build WM 6.5 to come out so I can play with the phone some more.
