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?

Keith says:

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?

Anonymous says:

It's very safe. I used it to upgrade from the UK build of 1.5, and everything works perfectly.

Anonymous says:

Does there have to be an "SD Card" folder? Every time I try it says the update.zip file can't be found.

Anonymous says:

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

Anonymous says:

That was it. Thanks!

np glad it worked! got my cuz's g1 updated

surveyor.com says:

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.

halla says:

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.

stephen says:

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

Anonymous says:

Can we delete the update.zip once we are finished installing?

Anonymous says:

yes, you can delete it after the update. That is what i did. J

Joe says:

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

stephen says:

i did that still no luck. :(

was that little chip with an orange arrow normal!?

Christina says:

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

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?

Tallbruva says:

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.

USg1user says:

Updated to 1.5! Awesome!

Anonymous says:

I want to update it, will it interfere or conflict once the over the air one comes out?

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

mike says:

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.

Anonymous says:

Thanks a million. I am in India, hence no OTA updates, but this is working just fine

AJ Paco says:

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??

Dr.Jeckyl says:

Worked like a charm. Awesome find!

Godwell says:

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.

Godwell says:

Do you or do you NOT need rooted G1?

Godwell says:

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

I LOVE IT!

Thank you Central and Android-DLS.

Tmobile...(no comment).

Degel says:

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

Tallbruva says:

Is it me, or does the phone seems to respond faster with Cupcake?

Tallbruva says:

Sweet!!! They improved the audio too! It was good before; now it's even better!

gmv3 says:

If u do the 1.5 update ur self...
Wat happend once the ota come threw

Worked great. Thanks!

Anonymous says:

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.

Anonymous says:

That should read SD card NOT SIM card...sorry.

j says:

it keeps aborting what do i do

mike says:

do you need root to download this update yes or no please someone answer????

Anonymous says:

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.

Anonymous says:

j says:

it still does not auto rotate y

Anonymous says:

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

ashelee says:

I tried to download it and it said my phone doesn't support this download or something

Anonymous says:

I am having this same problem, did you resolve?

Tallbruva says:

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.

Anonymous says:

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

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?...

Anonymous says:

A virus? That's the biggest leap to an illogical assumption I've ever heard.

On the phone with tmobile. They told me any tinkering with the software would void the warranty. Anyone know anything about that?

Tallbruva says:

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.

Mike A says:

i just got my OTA updated tonight!!!! :-) i live in LA. just playing around with it now...

Anonymous says:

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!!!!!!

Godwell says:

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!

Anonymous says:

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?

Anonymous says:

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.

Godwell says:

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.

Anonymous says:

Is there anyway to tell that this is the same as the official OTA update?

Anonymous says:

Ok can someone please tell what to do if you already have a rooted phone.....(rc33)......

Anonymous says:

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

sammyp says:

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.

Tallbruva says:

Sure you didn't change any settings? I'm getting HTML email and embedded images without a problem.

Anonymous says:

so if you have the RC33 update you have a rooted phone? which also means doing these steps wont work?

gussde says:

Worked perfectly on my unrooted G1

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?!

Anonymous says:

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.

Darnell says:

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

Sergio says:

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?

Michael says:

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.

Michael says:

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??

Michael says:

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.

Oscar says:

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.
