Forthcoming T-Mobile G2 / HTC Hero 2.1 update in Europe

Hello,
I rooted my phone this week. T-Mobile in my country never provided an update for my T-Mobile G2. So my phone still runs on build 1.76.110.6.
I'm consider to install a custom ROM, because this firmware is really slow :-(
But If I will wait a few weeks and T-Mobile provides the 2.1 update this time, will I still have root access after the OTA update? Or will I lose the root access?
Are there any good and stable, full hardware supported custom ROMs with Android 2.1?
Or what's the best custom ROM at the moment for the HTC Hero/T-Mobile G2?

1. There is an update for T-mobile - have you ever checked the HTC support page? It is still v1.5 but its an update... (will remove root)
2. 2.1 is unlikely to be released by t-mobile in the next couple of weeks, you're probably be looking at a month or so and I also don't think OTA updates are supported on your current build. Also you will NOT have root and probably won't be able to easily downgrade again to gain root access.
3. There are lots of custom roms try reading the hundreds of other posts asking which 2.1 update to use. They are all about the same stability wise and realistically speed wise too, though some vary to a very minor degree.
How exactly did you get root in the first place? Or are you talking about a recovery image installed?

1) I couldn't download the official update from the HTC website, because you have to provide your serial number. And with my number I'm not allowed to download the update. Because I own an T-Mobile G2 instead of the "real" HTC Hero
2) If I install the latest update from T-Mobile/HTC I lose my root access and it could be hard to get it back again :-( That's bad
To get root on my phone I followed this tutorial:
phandroid.com/2009/08/04/how-to-gain-root-access-on-your-htc-hero/
(there are other similar tutorials out there)

Have you contacted them about this? The G2 is just a brand name, they are exactly the same phones as the Hero's and T-mobile doesn't actually sell any "Hero" phones just the G2. Therefore, that update is definitely for you.
Alternatively you could install the update using the exe found here: http://forum.xda-developers.com/showthread.php?t=559622
Once again bear in mind that this wipes your data and will remove root and you may have a hard time getting it back.

Yes I contacted HTC and the answer was that I had to contact T-Mobile in my country. They told me that I lose the warranty if I install a update from the internet, because THEY didn't provide it.
But in other countries (e.g: Germany) T-Mobile provides this update.
So what should I do now? What's the best solution? Install an official HTC update and lose root access or install on of the custom ROMs out there?

2.1 ROM, super duper quick, backup your apps via titanium back, then restore once you have flashed the new ROM. Maybe a good idea to backup messages etc if you want them

Should I install Nandroid before flashing?
At the moment I "only" have root access and not installed any additional boot loader or other software/firmware.
Would like to try your suggested ROM (Cronos Droid Version 1.3). Do I have to wipe my sd card to install this ROM?
And do you run the Non Overclocked or the Overclocked version?

[Q] How to Upgrade to Gingerbread on Carrier Unlocked Phone

Hi there,
I have an Atrix, carrier unlocked phone on the Rogers network running froyo. I would like to upgrade to the latest gingerbread firmware available on the Motorola website. I have a couple questions before I attempt this:
1. Dose it matter which carrier firmware I use, the AT&T or the Bell? If so how do I know which is the correct one to use? Since I bought the carrier unlocked phone off ebay it could be either an AT&T or a Bell.
2. Will the carrier unlock survive the firmware upgrade? Or am I going to have to get my hands on an other unlock code or something?
3. I am thinking about getting a dock so I can use the webtop thing. I have read that there is limits on the webtop based on your data plan. Is there something that needs to be modified to have this work or does the unlocked carrier bypass any of the these restrictions an allow the webtop to work?
Any help on this would be appreciated.
Thanks

1) yes it matters. How did you plan on updating? To check what firmware you are on go to settings about phone
2)yes the unlock should survive it gas to do with the sim.
3)The limits for webtop have to do with AT&T and their limits on tethering

Thanks for your response. As for the update I was planning on following the instructions on the Motorola website. Copy the firmware file to the SD card and then select system upgrade.
yeah i dont think that will be a problem, just check what firmware you have
BUT i would reccomend using a custom ROM
Reasons
-they are based off motorolas firmware and are very stable
-tweaked to give better performance
-are deodexed. meaning you can apply themes to your hearts content and really personalize your phone
Hi marko! thanks for your help on this. What rom would you recommend? I am looking for stability and speed, over themeing and customization.

After having tried them all, Nottach's DarkSide is the fastest & most stable. Also ext4. Make sure you do a fastboot wipe before you install it so that you start on a clean system!
Happy flashing!
You don't have an update available via OTA yet?...
Sent from my MB860 using xda premium
So after doing some reading and poking around in the dev forum I think I am going to not bother with the stock Motorola firmware and go straight into a custom rom as you guys have suggested. I have a couple quick questions first, and would appreciate any guidance on the best, safest and easiest way to do this. I have read through the, noob and flashing threads but I can’t seem to find a definitive answer to this.
So since I am running stock froyo, is the install as simple as unlock bootloader, root phone and load on romracers CWM and flash away? Or do I need to worry about gingerbread bootloaders? My understanding is not all roms have bootloaders in them.
OR do I use RSD lite and loaded on the stock 2.3.4, unlocked .sbf file, root phone and load romracers CWM and flash. Which I think this method you can no longer go back to froyo, if need be for whatever reason.
I would prefer to keep the froyo option open, but I am not married to it. Plus I would prefer to do this not using RSD lite as I have had some bad experiences in the past flashing my Samsung cappy with the PC program odin.
Thanks again for your help.

Still confused - Rooting - I know I'm sorry:(

I read a few guides regarding rooting and I'm still sort confused by some aspects of it which still eludes me.
I have a UK T-mobile S2 which is brand new and while I adored this phone and happy I got this over the 4S. The one aspect I'm not too keen on was the amount of bloatware which this devices comes with.
So using this guide here:
http://reviews.cnet.co.uk/mobile-phones/how-to-root-your-samsung-galaxy-s2-50004972/
1. However, what kernel do I need for it? So many to choose from?
2.I like Touchwiz and I want to keep it however, is there a rom to get rid of all the bloatware that I don't need like T-mobile recommend apps. I'm not sure what rom I need or do I need something else?
3.Unrooting is possible since I may need to send it back to Samsung since there's a screen problem which isn't major but I don't want to send it straight back at the moment.
Thank you for your patience, and help.
just install the right one from here
http://forum.xda-developers.com/showthread.php?t=1103399
then use cwm app to make a back up of your current branded rom. Then either download titanium backup form market and use it to uninstall any apps you dont want on there or flash the non branded rom for t-mobile from here

[Q] Couple things about Atrix 4G

Hi!
Im proudly owner of motorola milestone. It was great phone with blocked bootloader, but I'm old and I had in my live some "normal phone" so I didnt cry about locked BL. I simply dont need unlocked BL because in time when I play with Stone We had a lot of rom by recovery.
But from time when I made some weird things took a lot time and a lot of things change in new smartphones so I have some questions for You.
1) On milestrone I could without problems update 2.1>2.2 and downgrade it to 2.1 with official sbf, and I know Atrix has official update from 2.2 to 2.3. I still can make this without problems? (from 2.2>2.3>2.2 and other ways...)
1a) I saw news about update to ICS, and it Was on motorola page (forgot which one). It will be in this year? (official q3 2012)
2)Do I need to unlock BL to use "roms" from recovery? Or I need recovery only?
(like neutrino / cm7)
3) I will not use any of atrix accessories, it will be for me mp3 player, phone and maybe sometimes game console. I still need to unlock BL? And if yes, for what?
3a) when we are speaking about games, every rom fully support tegra?
4) Is something what I need to know about atrix 4g before I will purchase it?
5) Can any user of this phone who live in germany tell me what about using germany mobile network?
sorry for lame questions and thanks for answers

1. No. Due to bootloader changes between 2.2 and 2.3 you can't just use an sbf. You can however flash a fruitcake which is just a copy of the boot and system partitions. Doesn't do anything to the bootloader. Your bootloader needs to be unlocked to do this and you will need to flash a customer recovery program such as CWM. However, you can use an sbf if you are going between the same version without unlocking the bootloader. Example 2.3.4 to 2.3.4.
1a. Yes. We will should be seeing an ICS upgrade anytime from now to September.
2. Your bootloader will need to be unlocked and a custom recovery will need to be flashed.
3. If that's all your planning to use it for then there really isn't a reason you will need to unlock the bootloader.
3a. Every rom should as far as I know.
4. Some people report that the battery gets quite hot and causes problems. I'm lucky to say that I've had the phone for over a year and haven't had an issues.
5. Sorry, can't help you with question 5, but I hope I was able to answer the rest of your questions.
so without unlock bootloader I cant use custom recovery? In my MM I have recovery and from this recovery I can start "custom" and from this custom I can recover roms...
And what about update from 2.2 > 2.3, when moto release 2.3 for atrix it should be possible to update it without unlock bootloader? Only with OTA?
For god sake, why everyone are making us soooo much problems about custom OS... This is my phone and I should make with it what I want...

If you are planning on flashing custom roms you will need the bootloader unlocked. Going from 2.2 to 2.3 you don't need an unlocked bootloader. You should be able to either use the OTA option, the sd card option, or the update program from moto via the pc.
