Sometimes, enough is enough. We've all been waiting for the Android 1.5 Cupcake US to come to our G1 phones since...who knows when. We gave you guys the details on how to manually upgrade your G1's to Android 1.5 via the UK update but that meant certain sacrifices had to be made (Amazon mp3, voice search, etc) in order to take advantage of Cupcake's goodness. Luckily a US version of Android 1.5 has popped up so you can now manually install the Android 1.5 Cupcake US version onto your G1.

Yeah, this is pretty close to official. And yeah, we know the rollout is supposed to begin tomorrow but geez, we wanted this 6 months ago...we don't know if we can wait another day! Here's how to get the Android 1.5 Cupcake US version onto your G1:

  • Download the Android 1.5 Cupcake US Version File
  • Rename Downloaded zip file to update.zip
  • Copy 'update.zip' to SD Card
  • Turn off the phone. Press and hold HOME+POWER to reboot
  • When you see the triangle with an exclamation point press ALT+L
  • Press ALT+S to begin update process
  • When prompted, Press HOME+BACK to reboot
  • It may reboot a few times, don't worry

It seems safe, but who provided this update? Does TMobile or Google release all of the over-the-air updates online?

Okay, I read the instructions, clicked on the link to go to download the file, it brought me to a page and it said Cupcake 1.5 I clocked on the link that said download: Google File, it popped with a box saying certificate has expired, I then it continue anyway, and it sent me to a page saying Google error, Server error, has anyone else had this problem?

check that u really renamed it update.zip and not update.zip.zip if ur os is not showing extensions u screwed it up.

Update worked fine for me except for loss of all browser login data (though it retained the bookmarks). Thanks for posting this. Even with the tiny buttons, I prefer the touchscreen keyboard to the phone's keyboard.

I have the JF 1.5 modes version with the rc33. I'm sticking to my JF version cause it's very responsive besides they are both the same anyways with the same fubtionality. Halla.

mine doesn't work. every time i try to update it says no such file or directory install aborted. help??

when you change the name of the file, change it to "update", not "update.zip", if it can't find the file.

I was paranoid about doing it, but this IS the offical update!! it works for me, but I'm at work and slowly getting around to the newness of the OS! already liking it... about to hookup my new stereo bluetooth :D

It didnt do anything for me =[ its still rc33. I went thru process fine, it "updated" booted up like normal and everything is the same =[ what went wrong?

Hello,

I purchased an unlocked g1 off ebay, when I tried to update I had a strange screen with jf 1.41.

When I tried to update it said my update was unsigned and canceled ... how do I proceed?

Looks like you have a rooted G1 with the JesusFreak RC-33 firmware. XDA-Developers.com should be able to help you out.

P.S.

Just applied the Cupcake update to my G1....Camcorder is decent. Transitions polish it up nicely.

I'm happy to say I'm typing this comment on my new soft keyboard.......update worked flawlessly I'm really happy I did it..was so tired of waiting lol but its awesome nonetheless

yo i tried this download 7 times it does not work for me another fail to get updated ???????? any help would be cool i don't have root on my g1 either.

I did the upgrade and I love it so far, but what is up with the messaging?? Why does it double send whatever message I send out? Any help anyone??

I downloaded, renamed (not with 2 .ZIP either), followed to the letter and got UPDATE ABORTED file (BAD).

Please help! TMobile execs should be dragged out and shot for making people go thru this.

Nevermind...I had to redownload, is all.

I LOVE IT!

Thank you Central and Android-DLS.

Tmobile...(no comment).

After the update mine wouldn't reboot, had to pull the battery, but other then that, everything seems fine

Redownload the file and/or make sure you rename it to "update.zip" (without the quotation marks) and be sure to save it to your SIM card.

No, you do NOT need to root the phone. Rename the downloaded file to "update.zip" and save it to your SIM card then follow the instructions shown in the article.

You have to go to Settings--> Sound & Display --> scroll to the bottom and put a checkmark in the "Orientation" option.

Try downloading it to a PC, rename it per the instructions and copy it to the root of your SD card. Then it should work.

I did resolve...when you add it to your sd card right click on it and click on properties and click on details and it will more than likely say update.zip.zip so go back to the general tab and rename it just update...the system automatically inputs .zip so you dont have to do that...took me forever and a day to do it

yo it works!!!
its amaaazing!!!
i'm loving my cupcake. its got such good frosting on it
seriously, it was worth the wait. it runs VERY SMOOTH

Really, can't wait another day? There must be some reason that they would want you to install this on your G1. Perhaps because it is a virus?...

Technically yes. But you're not rooting the phone. Your putting on the same update they're giving you over the air. But if you're not paying for a replacement warranty, there's nothing to worry about.

These steps isnt helping me at all it isnt working...can someone help me seriously...when I go to press Alt+l it says on the screen it can not find the file...HELP ME!!!!!!

They won't know one way or the other. When the OTA update comes, just re-download. F*** T Mobile.

NO, its not a virus!

on my mac i get "untrusted server certificate" and on my windows comp it wont download.. but let me ask u this guys a have a file that some how i dl last night and it has the file name it is unzipped is that still ok?

I keep tryin and it wont work it says it cant open file...i follow the directions correctly...somebody help...wat am i doin wrong????

is it just me ? or does anyone not notice it. i manually updated first with the uk version and now i just did the manual u.s version. everything went perfect but , i still see the date the european version . it says 27-5-09. in u.s we write the month first. any one know how can i change that?

k i got it fixed. people that have the uk version. when u manually update to u.s version. make sure u do a memory wipe first. alt+w before hitting alt+s. or else you will still have some features from the u.k version. its best to start off fresh.

If the phone is having trouble unpacking it, try re-downloading it. The first time I downloaded it was 41MB and the second time it was 47.7MB.

do the same steps i had rc-33 also just dont name it update.zip just name it update it will automatically add the .zip

The email app was terrible before cupcake update. Now it's downright disgusting. What the hell happened to HMTL email or embedded images? WTF, you would think that they wouldn't make an app worse off than what it was. That's a first. Also noticing some other weird quirks. Like not automatically connecting to bluetooth headsets or wifi spots. Other than that everything seems like a good update.

I didn't get the Music widget with my Cupcake update. However, I did get an ESPN and RSS Reader, which weren't listed on the new features.

Music application is still available and the UI is greatly improved.

Also getting the "double text message" when I send a text via messenger... It apparently automatically double populates the "to:" field so when you hit send text, it sends TWO of the same messages simultaneously... anyone els experience this, or know how to stop it?

Hey guys, I've already set the option to autorotate, however, it's still not doing it. Could this be the .zip file I downloaded or am I doing something wrong?

Thanks for your help.

I have tried to do the update and have done everything suggested as far as renaming the download to "update.zip" and making sure it's not update.zip.zip. yet, it is still aborting when i attempt the update process. any suggestions?!

I use Windows Vista and by default the system downloaded the file as "zip folder" file type. It didn't work. I downloaded the file again as "all file" type directly into my G1 SD drive. Works without problem.

Is anybody phone takin forever to charge. It stays at 73% for the longest and when I restart it its at 99% what's up wit that. Like the update tho

I keep getting a "503 Server Error" when I click the link.

"Server Error
The service you requested is not available yet.

Please try again in 30 seconds."

Is the link dead?

Same here... Server Error... maybe the server is down - or maybe Google decided it didn't want people preempting them and manually installing it.

Bottom line, ANYONE who has already downloaded this file can upload it to a server for others to download... Someone just needs to do it.

I got all this done... but all my icons have disappeared and i also don't have the tab at the bottom of the home screen anymore. I basically can't do anything that can't be done via hard buttons.

WTF??

Ok, got it working... had to take the batt out... when it restarted it asked if I wanted to bypass DXTop (home alternative). I did, then, using regular HOME, everything came back. I then uninstalled and reinstalled DXTop and now all is well.

Just did the update, it worked just like the instructions said. One question to that have been using cupcake, when i have auto screen orientation checked, it still doesn't slip when i turn the phone. Is there any other setting that needs to be set. It still only flips orientation when i open the phone. has this happened to everyone.

This is a wonderful opinion. The things mentioned are unanimous and needs to be appreciated by everyone. The above thought is smart and doesn’t require any further addition. It’s perfect thought from my side.

Yes and confirmed !!!! All those well paid Google engineers have gone out and are eating our cupcakes. They are drunk. The greatest company on earth. LOL !!! Time to outsource work to India and China.....

Could someone post a torrent of the update.zip file? It seems like the file was taken down from Google's servers.

Easy to update. Anybody could do it. Camera is much faster and the video is neat. Keyboard does not come up in the horizontal screen.

ok, so i followed the instructions as closely as i can. i am still getting a message that says can't open/sdcard/update.zip(bad)

install aborted.

any suggestions.

tyvm, been waiting for this for a long time

If you get the error page just keep trying every 30 seconds and it will work. I had to try about 8 times then it started downloading. It worked perfectly! Thanks alot guys.

ok Ive done everything from with the .zip to without, checked the properties, dwnlded and copied, every single time all I get is update failed - I'm still on firmware 1.0 - do I need 1.1 to update and if so where can I find it to dwnld? any and all help is appreciated.

Thanks

Kay! i have a problem with my g1!! once i installed this manual update, i couldn't receive and phone calls from anybody.... when they call me, it would ring once to three times and a voicemail thing would start up... PLEASE HELP!!

Do I lose my root access after upgrade ?
I needed to downgrade to rc29 in order to root and then back to rc33 and now I have
Root access anywhere and afraid to lose it ...

I dont know if anyone has posted this or not but I was having a hard time trying to istall this and I said fk it. I saved the files twice one as update.zip and the other as update and it worked after that. Try saving it 2x there is no way it wont work then.

Will this update work with a rooted device?
Will it cancel the rooting of the device - meaning after the update will the device still be rooted?
