By 
atlp99 over on XDA was able to get a hold of the official Android 2.3.4 update for the G2 straight from those SD cards HTC sent out to T-Mobile stores to manually update customers. If human interaction makes you nervous or you’re simply too busy this weekend to drop by a store you can get your official Gingerbread fix by manually updating yourself!
Oh – and for those of you that jumped the gun and flashed (installed) the leaked 2.3.3 update that made its way around the Android forums not too long ago, you should be able to update to this official version with no problems. Here are the installation instructions via T-Mobile support forums:
- Download the 2.3.4 update for the G2 here.
- Once downloaded, place it on the root of your SD card (not in any folders). DO NOT rename it. Its name should be “PC10IMG” with .zip being the extension.
- This will completely wipe your phone (factory reset) so back up any data that is important to you. SMS, Contacts, etc. All apps will be deleted so back them up if you must.
- Turn off your phone and boot into bootloader (press and hold the power button and volume down at the same time).
- Once the bootloader is up you should see the “PC10IMG” being scanned.
- Wait for the phone to finish scanning the file. If done correctly the phone will ask if you want to update.
- Press volume up to confirm. The update process should begin after that.
- Give it a few minutes and make sure you don’t have a low battery. Shutting the phone down or pulling out the battery during an update process can potentially brick it (trust me, people do this all the time).
- Once the update has been successfully installed, the phone will ask to press the power button to reboot.
- The phone will reboot and you have a freshly baked 2.3.4 Gingerbread update!
As always, make sure you have a full 100% charged battery before attempting to update and Phandroid cannot be held responsible should you brick your device. We’re just the messenger, guys. Let us know in the comments if you successfully updated!

Thanks, Avneet!
oh! and this may freeze on the first time around just take out the battery and plug it back in and do it over itll upload in a matter of minutes! it happened to me. I took a ballys move and removed the battery after an hour and it loaded in 5minutes afterwards and now this works like a charm!!!
So is this update NOT coming OTA anymore, as was previously promised? I already upgraded to the leaked 2.3.3 build, and I’d rather not have to re-installe my hundreds of apps again, it was kind of a pain.

First off, if you have the leaked 2.3.3, you will never see the OTA. And if you go to the T-Mobile store, they’re just going to do this exact process, which will wipe your phone, so either way you’ll need to install your apps again. You could always use something like Astro to backup all of your apps to your SD card so after you install the update, you can just download Astro again and then boot all your apps from there.
Does this work with htc mytouch 4g too?
I think mine is frozen! Is it safe to pull the battery?
I’m kinda freaking out right now!
Someone please help!
this isn’t working… freaking out! I just pulled battery and I am now attempting again. I think I just bricked my phone! I really hope not though!
well I gave up… luckily… I just rebooted normally and the phone is still working.
I will wait for my OTA or go ask TMO for help.
Sorry for being a drama queen!
meh, forgiven.
Will this work for the t-mobile mytouch 4g
Of course not! This is only for the G2 phone
Well, I just tried it and it worked! Yay!
How long did it take?
Worked as advertised.
can someone please tell me how long the phone will update for after you press volume up? my G2 has been updating for almost a half hour and i dont want to brick it by turning it off. what should i do?
Mine updated in about 5 minutes, others have said that it has taken over an hour. The people that have had time issues said that they took out the battery and just did the process again and then it worked. Be careful, and let us know what happens.
i’m having trouble with rapid share when i download the zip file and try to open it…it says compressed file is invalid or corrupted am i doing something wrong?? and also do i need to unzip or extract to install it to my G2? thanks for the help guys :-)
No, you don’t need to extract/unzip. Just download and put the .zip file onto the root of your SD card.
so far i see a white screen and it says update is in progress do not power off the device how long will it take??
Well, you should also see what kind of looks like a vertical progress bar at the top right of your screen. Just let it do its thing. Mine only took about 5 minutes, others have said that they waited almost an hour and it froze up, so they took out the battery, rebooted, and did the whole process again and then it worked.
so this is what i see….
HBOOT
Parsing… [SD ZIP]
[1] bootloader (with a little – next to it)
[2] radio_v2
etc.
am i doing it right or i have to do something else??
That sounds right, is it still doing things or has it been stuck on the same screen for a while? When your phone is off, then you hold volume down and press power to turn it back on, it will automatically detect the .zip file that you put on the root of your SD. It will scan it, and then ask you if you want to update, and you have to press volume-up for yes. After you do that, you do nothing else, the phone takes it from there. Out of curiosity, was your phone fully charged up, 100%?
its been stuck on the same screen for a while and i did the whole vol. down and power button and let it scan for the .zip file then pressed vol. up for yes to the update and my phone was fully charged also i double checked that before i started.
“8. Give it a few minutes and make sure you don’t have a low battery…”
I think a lot of people might be having problems because you need to make sure that your G2 is fully charged, 100%, before doing any of this. Don’t ask me why, I personally have no idea why it NEEDS to be 100%, but that’s what every forum on XDA always says, that’s what I did, and I didn’t have any problems.
Hey guys this is DCBatman from the T-Mobile Support forum… If you have any questions about troubleshooting, I will be lad to assist you! Go ahead and head over to the support page to see if your updating issues were solved… http://support.t-mobile.com/thread/4060?tstart=0
Why is this just not working for me whatsoever? I have a stock G2 running 2.2. I keep getting the HBOOT screen and never moves on. HELP!
This way worked http://support.t-mobile.com/thread/3447?start=0&tstart=0
The above version/way did not work for me.
And yes, I followed all the directions to the letter.
That way won’t work if you have the leaked 2.3.3.
This worked for me too. Thanks!
Why post a link to something we got to fucking sign up for. Where a link to a direct download?
Guys, just attempted this update on my wife’s G2. It’s been stuck on the “Update is in progress. . . Do not power off the device!” screen for an hour.
Any suggestions?
Could not get this to work, after attempting several times. Used the link from Mike Cristancho and had no problems.
What link?
That has been happening to me for 2 days and I wasted about 8 hours and nothing, this was in the store too. What a waste, I don’t know what’s going on. Let me know when you get something done.
I had never done anything like this before but its working great and I’m pretty happy.
