I always updated modems without wiping. Never had any problems, knock on woody.

Why woody?

Auto-correct. He did it on another post too. Funny though.

Philliman, not sure but you might run into problems with so many people pulling the modem from your Dropbox from both this thread and the one in General. Might want to host it somewhere else, JIC. I can host it on Dev-Host or Towle has a mirror thread as well.

Cool. Host it. Don't know too much about it. I just clicked share and created the link then pasted it. Just post the link when you host it so I can save it please. Thanks for the info too

Another Way to Install this, while saving Backup of old one

Another Way to Install this, while saving Backup of old one

Thanks for this THREAD OP...

To Update Modem to "T999UVDLJC"
1) Download the file on Post #1
2) Extract "UVDLJC.bin" and put it on your Internal SDcard of cell.
3) Run Terminal Emulator (app from Market) enter this code...

su {this is need 1st time for Superuser Permissions}

dd if=/dev/block/mmcblk0p1 of=/sdcard/modem.bin bs=4096 {this made backup of old "modem.bin" to Internal SDCard it is 60.00 MB}

dd if=/sdcard/UVDLJC.bin of=/dev/block/mmcblk0p1 {this installed New Modem}

4) Reboot and check Settings - About Device
5) Save "modem.bin" to safe spot on PC or know where you can get it, if need be.
6) Enjoy

Are you sure that this t999UVDLJC modem works with an unlocked
Samsung i747 AT&T device on Tmobile cellular network?

A few weeks ago I tried a Tmobile modem and it did not brick the
phone but the phone did not get any signal bars and I could not
make or receive any cellular phone calls.

The the only way I could fix it is by flashing the i747 modem
to get the phone working properly again.

My baseband right now is: i747UCDLK3 which works properly
and with this i747UCDLK3 modem I can either use a AT&T sim
card or an Tmobile sim card. My phone is on the Tmobile Network.

Doesn't the zip already back up the modem? Jovy's did, figured this was a repost; perhaps not.

No point though because all modems are readily available.

It should create a back up of your old modem. If not you can get it from the modem thread. Won't hurt to try

Yes, the updater-script is the same in all modem zips (at least the ones in my mirror thread) and it does backup the old modem. But if something goes wrong, I always prefer to wipe both caches and re flash a new modem anyway.

Cool I used to have to flash radios in fast boot mode on my HTC gonna flash it when I get off work tonight thanks.

This. I got so used to flashing radios either with fastboot or Hboot, when people say 'oh just flash in recovery' I couldn't believe it.

Also, I can't really comment on battery improvements but as others have mentioned, I seem to be getting better signal strength.

    *EDIT* REMOVED FROM DROPOX AND CHANGED LINK TO A MIRROR PROVIDED BY Towle. Thanks
    I only flashed this using TWRP recovery.
    I don't know where else to post it.
    Just trying to help. I'm using Frosty JB 11.5 rom and my reception and data speed has improved greatly!

    In my build prop, I only have these:

    ro.ril.hsxpa=3
    ro.ril.gprsclass=12


    Looking at DocHOliday's OP, there's also other values that can be tweaked but I dont seem to have those in my build prop. Anyone shed some light here?

    Just copy and paste the ones you want if they aren't there or type it in manually.

    Data Tweaks for HSPA+42 Supported areas:
    ro.ril.hsxpa=3
    ro.ril.hsdpa=24
    ro.ril.hsupa=6
    ro.ril.gprsclass=12
