Note! You must be on you g1 not you PC to do this, you will not lose any data or info on the phone, once your are finished you will be back at normal with the new update!

Ok so you have to have Linda’s file manager, this is a free download on the Market, Just open Market on your g1 then select search and type in Linda file Manager, it will show up and download it.

1- Go to the market and download Linda File Manager

2- Go to the Direct Update download Link Here , (you might get a error message when that page loads, Just refresh it, and you will see the download arrow on the top left corner of the screen)

3-once you got the file downloaded,open the linda file manager and click the SD card, (when you click this a pop up box will appear select the Linda File Manager)

4- once the sd card screen loads, scroll down to the Downloads folder and click that.

5-Once in the downloads folder, scroll down you will see a file called PLAT-RC-33…..Long click it and a option list will pop up, scroll down to Rename.

6-Rename the file update.zip

7- once you rename it, long click it again and select Cut

8- then hit the back button (the button the the left of the power button) this will bring you back to the SD Root.

9- click the menu button, then select paste,( scroll down to make sure the update.zip file is in there)

10 Power off you g1

11- while the g1 is powered off Hold the Home button(DO NOT LET GO OF THIS BUTTON)and PRESS the power button for about 1 or 2 seconds, The phone should start to boot up.

After the G1 screen goes away you will see a screen with a triangle on it,(you can now let go of the home button)

12- once you let go of the home button, on your keyboard press ALT+l this will bring up a screen with yellow text.

13- once in the screen with yellow text press ALT+S

14- let the update install 100% and read the yellow text, when it says press Home+Back to reboot, Do so.

15- It will be a kinda long/weird reboot but just bear with it and don’t panic, the phone will boot and you will have the new RC-33 update!!

Enjoy!!

Any Questions please ask me either here or Here

I have the G1 without the data plan, and everything works fine with no problems.

The only thing I did have a problem with is MMS, but I got around it by going with the settings I used on my old unlocked HTC 8125:

Menu > Setting > Wireless controls > Mobile networks > Access point names

Once you get in there, scroll down until you see T-Mobile US and input the following settings:

NOTE!!! DO NOT CREATE A NEW APN, YOU MUST USE THE Tmobile US APN for this to work

Name = T-Mobile US
APN = wap.voicestream.com
Proxy = 216.155.165.050
Port= 8080
Username= None
Password = None (delete the 4 digit PW that is there)
Server = Not set (also delete the 1 digit PW there)
MMSC = Unchanged (do not change it)
MMS proxy = 216.155.165.050
MMS port = 8080

MCC, MNC, and APN type all stay they was they are.

Now as far as remembering the old information goes, you can always go into T-Mobile US 160 (right below T-Mobile US), which has all the same settings as T-Mobile US including the password. All you have to do is copy and paste it.

How do you copy and paste? To do this let’s say you go into T-Mobile US and where it says “Name.” Click it and the edit box will pop up; hold your finger on the name, and then another box will pop up; click “Copy all” (this is only going to copy what is in that box). To paste, you go wherever you want to paste it and do the same steps.

You can also check out this blog where I post at for other answers and questions you might have..Please read through the blog before asking any questions as there might already be a answer for you Here.

Also If you have a unlocked g1 on At&t network Here is a setup for you to use. Please if anyone uses these setup post and let everyone how it works out for you..Also if you have any problems or questions.

Ok so first follow the steps I listed above to get into the Apn and go the the Tmobile US as I also listed above in my tmobile setup.

Name: AT&T

APN: wap.cingular

proxy: none

port: none

username: wap@cingulargprs.com

password: CINGULAR1 (case sensitive)

Server: none

MMSC: http://mmsc.cingular.com

MMS Proxy: wireless.cingular.com

MMS Port: 80

MCC: 310 (Do not change it if yours is different)

MNC: 410 (do not change it if yours is different)

APN Type: none

Now as far as i know the “MNC” is location sensitive, from reading on other sites the MNC is usually just 41 on the east coast and 410 near the northwest region (not sure on any of this it’s all trial and error)

turn phone off then back on again and you should be able to send/receive mms messages
You can put this in my last message if you like LOL.

i tested outgoing/incoming calls, voicemail, outgoing/incoming sms/mms, android market, gmaps, and browser, all worked AMAZING
