Reinstalling WM6 2.27 - Palm Treo 750 ROM Development

I already upgraded my Treo 750 from WM5 to WM6 using the APAC 2.27 downloaded from Palm website. My problem is my firmware. It is still 1.12.0c.00. How could I trick the TreoUpdater into again reinstalling the 2.27 ROM into my Treo?
Thanks.

Use the SD-Card methhod, this will work.

Upgrading K-JAM G2 to WM6

i have the K-JAM G2 version with SPL/IPL 2.16 OS 2.16.9.1 (if it makes any difference).
i want to upgrade to WM6. i was wondering if i at all should. it has a 200mhz processor..
also i was wondering if WM6 can at all be installed on this device since most the roms i stumbled into were for G3/G4 phones.
also, if i try to install WM6 and it doesn't work and i can't load my phone again, how will i be able to flash it back to WM5?
thank you

Why do you want to unlock your radio? 1.54.07 Is the most stable radio, so far, for Palm Treo 750/750V. No drop calls or any other issue like the ones that affect the rest of the treo radio ROM's. Nobody complained yet.

Thanks for your input. I just want the freedom to do so, that is all.
Have you tried going back to original SPL and then flashing with original rom?
That's the only thing coming to my mind, I may be wrong...

I've used the KaiserCustomRUU (dload from Kaiser thread) and a Hermes Radio ROM (Hermes wiki) and the ones i've tried work fine (the latter ones).
currently using 1.54.30.10 and works a treat (t-mobile uk) - most stable rom i've used on my treo (connectivity/hsdpa).
may sound like a strange way to flash the radio but works for me... (the hermes shares a lot in common with the treo processor/radio wise)

Thanks my friend, will try and see what happens
sorry to be a bit noobish at this, but how can I upgrade my radio? I have a 750 at&t branded that was unlocked with WM5. I upgraded to WM6 with official (Treo750_2_25_ATT_EN_DesktopUpdater). As of now, my boot loader shows up as:
Palm Tr
IPL-0.20
Palm Tr
SPL-0.24.0000
My OS and Firmware shows up as:
Windows Mobile 6 Professional
CE OS 5.2.1239 (Build 17746.0.2.4)
Firmware Version: 1.54.00.00
At times I notice my calls get dropped and when they do the signal strength goes way down even though I have not moved an inch before a call starts. Before it starts, antenna bars are at least 3. I heard this radio version is the best 1.54.30.10. I obtained the herm_radio_only_1.54.30.10_customruu.rar, tried renaming RUU_signed.nbh to CHEEIMG.nbh, and using bootloader method, but after the three colors, it says Loading..., then displays "00068002" at the top center, then back to the three color screen with those IPL and SPL numbers listed above and the word "Serial" at the bottom center.
How can I upgrade to this and what tools do I need? thanx
Edit: btw I am using this on tmo us network

nevermind, I took the plunge and ran step 1 with CheetaUnlocker:
http://forum.xda-developers.com/showthread.php?t=334100
SPL version displays 1.40.OliNex.
then I was able to flash the radio to 1.54.30.10. Let's hope this is better than 1.54.00.00.
Are you still using the ATT 2.25 ROM? The ROW 2.27 ROM is a lot better. Check it out.

I just went to the 2.27 ROW from the 2.23 ATT. Radio stayed at 1.54.30.10.

WM5 downgrade on G4 Wizard

Hi,
Ages ago I upgraded my G4 wizard to WM6.1. Now it turns out I need to put it back to WM5 - but can't find a RUU to use.
The original ROM was from O2, but that is not vital. Does anyone know where I can get a suitable RUU from? I found one that would, I think, only work with a G3 device, but have not found one yet I can use...
Cheers,
Ben
I thought I had found one, but the RUU complains that it is the wrong version (Error 300) and I get nowhere. I still have WM6.1 working fine... how infuriating :0p
Well,as you say its a G4 and upgraded to wm6.1,ok
First,how did you upgrade to wm6.1,which method did you apply to upgrade,was it SoftSPL or HardSPL ?
If you applied SoftSPL,then,just simply download official stock rom and flash it,it'll work,but if you applied HardSPL and the IPL/SPL are changed,then first you'll have to Remove HardSPL,revert back to Original Official IPL/SPL of the carrier and then you'll be able to reflash wm5,ok
Let me warn you here,if the phone is HardSPL and you flash any Official stock rom without removing HardSPL first,will 'Brick' your phone.

hi there,
Actually i had the problem with G4 on how to upgrade to WM6, I tried but no luck, haven't tried either SoftSPL or HardSPL yet but when I flashed my WM5 original ROM, I didn't have any backup at all so I kept searching answers here for days, & finally I tried the Wizard Love ROM which one of the Senior Member here said it will work. It works for me & now I'm using WM5 Wizard Love Rom with CID LOCKED.
Hope I can help u with that..
P.S.
If anybody can teach me how to upgrade my Wizard G4 (T-Mobile/MDA - black) to WM6 (any rom) or the download links for SoftSPL ONLY! they said it's safe..
Would gladly appreciate!
Thanks...
