[Q] How to get Froyo: T-Mobile unlocked now on o2

My desire was purchased on T-Mobile (has T-Mobile startup screen), I also bought an unlock code from them. I'm now using my o2 contract sim in the phone. I'm interested in updating the software to FROYO but have no idea how to go about it.
I don't want to do anything complicated and am happy to wait for an official release. I've read the network sends an update direct to your phone. In my case would this come from T-Mobile or o2?
When I check for system updates it says none are available. My software number is 1.15.110.11
I've looked around the forum for ages but I still can't get a definite answer to my question.

You can be waiting for a very long time for froyo from a network provider.
It's easy to debrand and upgrade your phone. Create a goldcard & download an official ROM. Then you can simply upgrade OTA. There's loads of guides on this forum.

Hi there!
Understand your situation, since I had almost exactly the same circumstances (mine is running on orange)! I couldnt get a definite answer either, so bit the bullet anyway and did it, here is how:
1-rooted the phone by UnrEVOked method (really couldnt be bothered by the goldcard etc method; this method was easy, just had some driver install problems since the guide isnt too good on this point, but its easy to figure it out)
2-Installed the new radio
3-installed the generic rooted 2.2 ROM http://forum.xda-developers.com/showthread.php?t=741775, just by doing an easy straighforward update from the sdcard by going to the bootloader.
Phone was still UNLOCKED,and all running ok. Just had an issue where the phone would say "sim card changed, do you want ot load settings etc". Say NO, otherwise you lose your wallpapers, scenes, etc settings, and you have to redo the whole shebang.
Hope your experience is same as mine, im a noob too, so dont take anything for granted (your phone may have different firmware from mine etc), and make doubly sure before you go ahead!
Good luck.

Hi mate.
I'm in exact the same situation (German T-mobile 2.1 Softnumber: 1.15.110.11). Your guide looks awesome!!! Can you please please please write it in a bit detail?? from a factory branded 2.1 to root, then to froyo?? please??
I read the UnrEVOked guide from rootmydroid.co.uk
but looks like I only need to the first half for your step 1?
does it root the phone ? does it wipe all my settings and apps???
I also don't know what to do with the radio in your step 2??
can you please help??!! THX soooooooooo much !!!!

Hi thanks for the replies, very useful info.
Does rooting the phone invalidate the warranty?? That's what's putting me off doing it and why I'm happy to wait for an official update.

Hey forgot10!
The step 2 of unrevoked guide is installing the ROM of your choice. Just pick the new ROM you want (from many here and other forums, I just picked a rooted generic 2.2), and install as per part 2 of the unrevoked guide.
2.2 requires a new radio, which is linked and shown in http://forum.xda-developers.com/showthread.php?t=741775. Installing the radio doesnt wipe the data, but you seem to need to WIPE (from the recovery image) before putting the new ROM. So use TItanium Backup, or MYbackup, to save your apps, and user data on the SD card, then when the new ROM is installed, you reinstall one of those apps (from market) then rewrtie your apps/data!
As per warranty, check the other threads to be sure, but i think, yes it does invalidate your warranty, but im not 100% certain!
Regards

Thanks mate! it make much better sense for me now!! Im gonna try it next weekend!!

Can you change rom without rooting?

I have a T-mobile uk branded desire (firmware version 2.1 -update 1 )
(software number 1.15.110.11), I dont want to root as i want to keep the warranty, but the low volume problem is really pissing me off, I tried to watch a film while stuck on the underground today, I could not hear a word of it, even with hi end sennheisers, its really pissing me off!!!
I have been told that switching to the stock HTC rom will solve the issue.
If possible pls explain how? I am an android newb and will need help.
Many thanks in advance.

sadly, no.
But if you have a problem, you can keep a backup of the stock HTC sense rom, and restore it. Additionally, you can restore the recovery to stock (I think i saw it somewhere).
After all that, you are good to go. Warranty still valid, and you can RMA it

Thanks for the reply, pls remember I am a newb, how do I do this???

Root your phone, do what you want with it, just keep this handy...
http://shipped-roms.com/shipped/Bra...00.28U_4.06.00.02_2_release_127570_signed.exe
It's the current T-Mobile UK stock ROM and can be reflashed at any point to return to stock for warranty purposes (link may go down occationally so keep trying until you have it)...to reflash the stock ROM just make sure you have your Desire connected to your PC with HTC Sync and run the file - simple as that!!

I really dont want to root it to be honest, the phone is perfect except for the media volume! Do you think if I contacted htc they would be able to tell me how to change the rom without rooting it?

You CANNOT change the ROM without rooting, and HTC wouldn't tell you as it's breech of their warranty...just root it, you can always go back to stock if need be using the file I posted

Rooting isn't for everyone. If you have doubts about it, you should not do it. It's better to read some more about it than to hastely brick your phone. Most bricks are solvable these days, but it is no fun to do. If you want root just for the volume, it's not worth it if you don't know what you're doing, imho.

I have a T-Mo branded Desire that I have de-branded to a stock ROM, it's been OTA updated to 2.2 and just this morning it OTA updated to the new release all without rooting.
You just need to create a goldcard (very easy using the helper program) which will allow you to install any stock RUU. I have left the goldcard in my phone as it works as a standard microSD anyway to avoid any problems that occur when updating with out a gold card in.
I can't post links as I'm too much of a newb around here but search and the links are there.

[Q]Back to factory defaults vs downgrade?

It seems I made the mistake of applying the last OA update. Which means no root. On the other hand, I need root edit gps.conf file, for a better gps fix.
After spending some time reading I found a way to downgrade - not sure if I will apply it, it seems a new update is coming.
Anyway, my question is - what is the difference between reset to factory default. Does it return my phone to the state I had it when I bought it, or just whipes all personal info without downgrading. I don't want to loose any data doing a reset, and now quite sure what the downsides of downgrading using the method described in ROM dev section. I am a but of a noob on Android topic, too... that is why I had to ask
Sent from my Desire HD using XDA App

very interested to know this myself - ive got a desire on telstra running:
2.26.841.2 and hboot 0.93.0001
iv tried just about every method out there to root it but no success (though i have come close)
i also have a gold card
if i go back to factory will i be able to root, and what is the best way to root his phone?
failing that - does anyone know anyone who can?
many thanks in advance

Factory reset wipes all the user data, it will not downgrade the ROM. So i'm afraid to get root you are going to have to downgrade as per instructions here

so does that guide work for the normal desire or just the desire hd?

sorted
ok sorted it all out and rooted my phone finally
having the phone completely up to date beforehand was probably the biggest hinderance
so in summary for anyone else in my (former) situation i can offer the following advice:
1. download downgrader from http://www.multiupload.com/CFAR720K5P and extract to readily accesible folder
2. copy PB99IMG.zip to sdcard (mine's 8gb kingston, had about 3gb of other stuff on there)
3. make a gold card as per http://forum.xda-developers.com/showthread.php?t=573866 up to the recovery step. i used the same card as above
4. run the win-down.bat file and follow all instructions (phone should now be running hboot 0.83)
5. remove the files you put in the sd cards root
6. download and run unrevoked3 (whatever version is 28,069KB)
7, you should be all sorted
you may find youself turning the phone on and off and and switching cards heaps, i found it useful to shuffle files around by selecting 'mount phone as disk drive' to move the files i needed, and then revert to charge only afterwards.
to arrive at this solution took me fn ages so i hope im helping another noob out there somewhere. experts are invited to shoot holes in my method.
many thanks to muskie for his passive assistance

[Q] Desire z 1.72 - temp root -ti backup -possible ?

As I am new in this waters maybe my Q is stupid for experienced members and I apologize in advance.
Found successfully the downgrade process and files for rooting my model but somehow i got used to sense atm and going trough rooting and restoring to factory ROM isn t exactly the dream work for noob in Android.
Is there a way to make a decent backup of the phone without perm root ?
Any other use of temp root?
Answers or simple redirections to other similar posts welcome and thank you.
Alex

bump
anyone ?

Anyhing changed in the meantime for 1.72? I also do not need root all the time, so temproot could be fine, but I see no solution so far.
Is it possible to keep phone officially updated and do temproot when needed?

[Q] Can you back up game save files without rooting?

Hi, im a noob and I've searched everywhere to solve this myself, and you guys are my last resort..... so go easy on me
Right, I want to root my Desire HD, But other guides tell me to Downgrade my firmware, because i have the OTA 2.3.5 Gingerbread. However, if I downgrade, I will lose all my existing data (no?) which would sting a little. I've used MyBackup pro to save everything else.... apart from the game save files which requires a root phone. I have tried to do it manually via the adb shell (as some guides out there show) but I still get the 'permission denied' when I try to access that data.
So what's the deal?? am I out of options then?
