How-to: T809 ---> D820 Flash

Complete instructions on how to flash, or update, your Samsung T809 (or D820) to better D820 firmware. It is laid out in easy steps, and I have all the free software you need for it.

I will keep this thread 100% up to date with Firmware to flash your T809 to D820

*If you do this, post on this thread how it went. Thanks

WHY flash your phone?

1. Battery Indicator is now 16 slices instead of 3, so you know exactly how much battery there is.
2. Your phone can Vibrate and Ring at the same time
3. Your phone no longer gradually gets louder when it rings
4. You can use Opera Mini (Internet Browser) Google Maps, and other Java applications that connect to the internet.
5. You can change what the up, down, right, and left keys do when you press them at the main page. You can change it from "Voice memo, phone book, camera, and SMS" to anything you want. Or keep them.
6. Your phone is now UNLOCKED so you can put in any SIM and go ahead
7. If your phone ever sporadicly shuts down on you, or restarts, this will stop that by fixing the software bug.
8. You can have Mp3s as your ringtone without having to do a work-around.
9. With the update, you get 10 more great things too...we're getting new updates every few weeks.

What you need:

1. You need a cable to connect your phone to your computer. (And a 9V battery) You have to get a linking serial cable to do this. I got mine off of ebay. Just search "T809 Serial Cord" (make sure it plugs into the serial port, and a 9V battery can be plugged into it)

2. You need to then download the software that you are putting on your phone. I advise downloading the version that I will post, but if you want version 2 or 3, request it and I will send it to you (there are no extra advantages to version 2 or 3. If the link does not work, please contact me) Advised T809->D820 software


Actually flashing your phone:

1. Make sure your phone is 100% charged. You will also need a 9V battery.

2. Turn your phone off, take the battery out, take the SIM card out (and leave it out) and then put the battery back in. Then attach the 9V battery to the flashing cord you have, and plug the cord into your phone. (The could should have previously been attached to the computer.)

3. You should have downloaded the D820-FC1 file I posted above. It should be zipped. Unzip it if you have not already. It should come with a program called "OneNANDDownloader_v18_Lite" - Open this program

4. You will want to click "BIN + TFS" and make sure "Don't Auto NAND Format" is checked. Then click on the BIN and TFS buttons, and direct your computer to the files you have just unzipped.

5. After this, press "Start."
You should see:
** Wait for Connect Request from Mobile...
** (POWER ON the PHONE!)
What are you waiting for? Do what it says. Press the red button on your phone. Hold it for about 3 or 4 seconds. The screen should not go on (although it may) but your the OneNand Downloader should start to show progress.
It will do something quickly (usually less then a minute) and when it is done, it will give you the option to "download"

6. Press download, and wait for a little over 2 hours.
When it is done, unplug it, put the SIM in, and have fun with your new D820.

The Update
What it does:
1. Automatically save sent sms to sent folder.
2. Battery indicator has now 16 "slices" instead of 3.
3. Fullscreen picture viewer: Push up button to view pics on fullscreen (for some reason this only works with pics in the mem card or downloaded images folder).
4. Fullscreen video by pushing left button (in case you have the slide closed and you can't push the 1).
5. Limit on GIFs individual file size that phone can handle now is 2.2mb instead of 300kb.
6. Java folder is 8mb instead of 4mb.
7. No confirmation for speaker phone activation.
8. Caller pictures show bigger on screen now, if they have enough resolution.
9. Blacklist feature. Handy to block certain numbers so the phone sends them directly to voicemail without even reminding you of him/her. You can access this feature from Phonebook menu inside the main menu. For more info go here to read the google translation of russian patch release.
10. DRM ignore. You can now send via MMS files with DRM protection (songs or images downloaded thru t-zones and things like that, I think)
11. Current time shown in phone call screen. So you can know what time it is though you're during a call.
12. Configure aspect of "desktop" screen from menu. Go to menu 9-3-3 (settings > display settings > text display) and see at the bottom for new options, like wether to show date and/or time or not, the translucent strip behind time/date, and the position. You can also hide the text shown at the bottom of the screen describing what those softs buttons do (this option is called "Cover title" in the menu)
13. Also this patch was added but doesn't seem to be working for me. Supposedly it lets you add numbers to existing contacts directly from the new number menu.


Updating - NEW UPDATE JUST ADDED

Download the updated Bin/Cla file:

1. This patch can be downloaded here: D820 Update

2. Unzip the file

3. Open OneNand Downloader. Make sure ONLY "BIN" is selected. Then click on the "Bin" button and point the computer to the file you just downloaded.

4. Make sure "Don't auto Nand format" is checked

5. Make sure: Phone is charged, you have a new 9V battery. Etc...Take SIM out, turn phone off. Connect the phone, hit start, turn the phone on. Then when you have the option, hit download.
It should take between 45 and 50 minutes.

Enjoy your nice new D820! If you have any questions, feel free to PM me.

Free Download D820DXFC2 (not advised - errors reported)
Free Download D820XEFG3 (somewhat advised - no advantages over FC1)
Free D820 Firmware Update

After flashing the phone, many people try to download the Gmail application from Google. This will NOT work! It will shut your phone off, or freeze, while opening the program. You can, however, use FlurryMail and access your Gmail in the same way. It is also completely free. I hope this helps
