[Touch Pro2, Tilt 2 Windows Mobile ROM Development] [SMAN]:
Downgrade messaging from 2.5 to 2.1 for people with lots of sms messages

Ok, so I'm a firm believer that if you don't have anything intelligent to say, then don't say anything at all, which is why i've been real quiet on this site ... until now. Being a heavy SMS user (and someone who keeps them all), i have a ton. Every time I click on someone in my SMS tab, it takes FOREVER to load them up and it looks horrible. This is due to the manilla 2.5 interface. Now, some people have tried to downgrade to 2.1, and it's worked sorta, but there have been a few issues. I've been playing around with it all day, and I think i've got a solution that should work to downgrade to 2.1, and keep notifications. I have NO idea how this will effect MMS as i don't use them, but it definatly makes sending SMS so much better and quick like the 2.1 roms. So for someone who sends a lot of sms each day, this is for you.

First thing first, get the manilla 2.1 messaging files from here: http://xdaforums.com/attachment.php?attachmentid=264390&d=1262800032

then we start the manual process of overwriting files and changing reg entries.

go and disable manilla: Start -> Settings -> Home-> Items Tab -> Uncheck HTC Sense -> Click ok

go into your windows directory on your phone (via total cmnder or something) and make a backup of the following files:

1de372cc_manila

3fee37f0_manila

24DBB12A_manila

57a92846_manila

64c98668_manila

247c62d4_manila

345f892c_manila

486d3b1a_manila

0828aea6_manila

3633be96_manila

People_Pages.xml

ManilaFull.xml

now, you will notice in the downgrade rar file, that most of these files will be there (they are inside folders, so it's best to put them all in a folder together NOTE: ManilaFull.xml is not part of this download)

Copy the new manila files and the people_pages.xml over into your windows folder.

Go ahead and deleate the ManilaFull.xml file from the windows folder (you made a backup right?)

also, copy People_pages.xml into /windows/ManillaXML/

Next up is registry changes. There was a reg file in that download. Go ahead and run that. It should make the following changes:

; Reg To Disable Messaging Client in Manila
[HKEY_CURRENT_USER\Software\HTC\Manila]
"Manila://PeopleDetail\\peopleMessage.page.hidden"=dword:00000000
"Manila://PeopleDetail\\peopleMessageClassic.page.hidden"=dword:00000002
"Manila://PeopleDetail_SIM\\peopleMessage.page.hidden"=dword:00000000
"Manila://PeopleDetail_SIM\\peopleMessageClassic.page.hidden"=dword:00000002
"People.MessageClient.Disable"=dword:00000001

; Tweaks Max SMS Per Page:
"People.Message.ItemPerPage"=dword:00000019

; Messages Font Size ( 0 - 8 )
"People.Message.FontSize"=dword:00000002

; Reg for GSM
"People.Message.IsCDMA"=dword:00000000

; Reg for CDMA
; "People.Message.IsCDMA"=dword:00000001

You can allways modify this by hand.

were not done here, cause there are a few more registry changes that need to be made, which will have to be done by hand.

In a registry editor do this:

goto -> HKLM\services\MSG and select the dll entry. Modify it so that there is an x on the end (MessagingService.dllx)

then go to HKLM\system\inbox\externalaccounts and rename the folder SMS to SMS.htc

now we are almost done here, and this is where most people gave up. since 2.5 has a different notification system, if you did this, while you would get txts, all it would do is play a sound and virbate, but it wouldn't wakeup the phone, and you won't see a notification in manilla (that's no good right). This is where i found a secondary fix.

Download this fix from Zez: http://xdaforums.com/attachment.php?attachmentid=232629&d=1254224466

install the cab (it will ask you to reboot at the end).

Once rebooted (manilla should still be offline at this point), we are allmost done. There is a small issue with the HTC notification manager that won't let you clear a read message notice once it happens. SO, go to Start -> tools -> Tweaks -> and select Notification Manager OFF

after this reboots again, go and re-enable manilla from the today settings and try sending and recieving sms. This has worked for me, and hopefully it will work for the rest of you. I didn't create the initial info, credit goes to these 3 links.
