Yeah big opps on my part on that. Let's see first you'll need qpst, a hex editor i use XVI 32 its free so. Also audacity beta for win7 or a ringtone site that will cut and convert your ringtone down to 30 seconds. I've had some luck going past 30 seconds because i have no idea what the limit is.

Once everything is installed drivers,qpst, and you have a hex editor try this.

1st. i power down the phone
2nd. hook up the phone via usb cable
3rd. open EFS Explorer, find your phone on what ever com port it is on. mines on 7 i think but it changes.
4th. Goto brew\mod\mr
5th. Make a backup copy of MrInfo.db also to note everything is case sens so if you do like the op said and delete it and make a new one with mrinfo.db your phone will probably be screwed maybe i dont know just what i've heard.
6th. Upload your 30 second ringtone bout 300KB i think might want to search to make sure thats the right size to be safe.
7th. check 5 and make sure
8th. turn on your phone let it boot up all the way then turn it off
9th. open up efs again and copy MrInfo.db from /ff/brew/mod/mr/ to a new folder and then open it MrInfo.db with a hex editor and hit search, replace and put for find 7C 30 7C 30 put replace with 7C 30 7C 33 this is so we don't add any chars that are hidden by hand editing. Once that is done save that to a new spot say make a new folder and save it as MrInfo.db.

"note had to edit what is above because i forgot that the phone does the work for you and makes a string like /ff/brew/mod/mr/devil.mp3|0|0 that you hex edit to say 3 at the end my bad sorry "

10th. Open up that file in notepad just don't touch anything or save it. Once open see if everything says like " /ff/brew/mod/mr/devil.mp3|0|3 " wont see the quotes so don't add them. If you open up your backup you'll see it says |0|0 so you know it worked if the name of your ringtone has a 3 at the end of the string.
11th. do 3rd and 4th again
12th. make sure your in /ff/brew/mod/mr/ overwrite MrInfo.db with the new one you made and "hex edited"
13th.close efs and disconnect your phone and boot it up. If everything worked you'll see the mp3 ringtone you uploaded under ringtones almost at on top of the list of ringtones select it and your done.

Ok now that's what i did if you noticed you backed up the MrInfo.db and didn't delete it. From what i've read you still can replace the MrInfo.db even if you screw your phone up by doing something like this since its not tested method by far by uploading it while it's charging when its off just like you did.

So that should be it, see the reason i posted search for the smooth ringtone hack lol you can see its the same method almost just a few steps changed. Again sorry if its confusing if it is just post and ill fix what ever you don't understand.

Going to edit this before i post it also to say this, every time your phone boots up it generates a new MrInfo.db with the files in "/ff/brew/mod/mr/" just with |0|0, with it being at 0 your phone cant see any ringtones such as wav,mid,mp3,etc. Just searching around the forums i've seen some people kinda brick the phone they have by hand editing that so I didn't want to risk it that's why i keep't saying hex edit the file. By doing so no windows chars can sneak in so it should be safe. Also see here for more info on hex editing the mrinfo.db i think thats it so post if you have problems

Great post. My cable should be arriving any day now so I'll try your steps out first. Thanks again.

I'm stuck pretty early in the process

When I have to remap the port thing. I have to go to phone info and press # right?
Well when I press it, nothing happens at all, however, if I press *, some thing pops up asking for a code with 6 digits.
I tried 000000 and it doesn't work.
I also tried pressing random buttons for a couple of minutes non stop and I just cant get it right.

Help would be really appreciated.

My phone doesn't appear in EFS Explorer either. I installed the Samsung driver from their website already. The phone is recognized by the computer but not in EFS Explorer. What's up with that?

[200 Motels]

Sorry, I should elaborate.

I installed the Samsung PC Studio from their website. I installed QPST.

Two devices show in the list of the configuration utility. I add them both.

Device Manager in XP shows my phone is on port 8. Port 8 and Port 9 both show in the QPST configuration utility but Port 8 says (no phone) and port 9 shows PT-Surf6300 etc.

In QPST Explorer it shows PT-SURF3600 etc and my wireless phone number on port 9. I hilight it and select Ok, the program becomes unresponsive for about 15 sec and I get a message "You have chosen a phone that does not support an embedded file system".

Any help?

Same thing happens in Windows 7.

This tutorial (mentioned earlier in the thread) worked great with a Koodo u450 Intensity.

A lot of small setbacks but they were eventually ironed out.

[Kainth01]

sorry for bumping an old thread but I find this is worthy of posting, I have a Telus Samsung Intensity and I've found a few secret menu's. I'm not sure if they work for Verizon or any other carrier but here's what I found.

if you type in one of these codes like a phone number, menu's appear with different options:

##DATA(3282)
##DEBUG(33284)
##TEST(8378)
##TELUS(83587)
##JAVA(5282)
##786#

All of these other than DEBUG and ##786# ask for your Service Code, DEBUG asks for 'Field Serv' and ##786# doesn't ask for anything, goes straight into a menu.

worked perfectly, thanks!

This defintely works on the Samsung SCH-u450 for Verizon. I just did it and it worked like a champ.

Hey everyone, it seems like there's a tedious process to upload ringtones into this phone. But which method is simpler: jawshua's or the one lanhoj posted. I don't have experience using any of these programs such as hex and QPST?

Brojo, I also have verizon if that makes a difference...which method did you use to upload ringtones onto your phone?

thanks
