Questions about rooting and unrooting - Android Software/Hacking General [Developers Only]

Hi.
Couple days ago I got my first Android device - HTC Desire.
Since I rooted my phone hoping that I'll be able to install apps on SD card, and find out that feature is actually expected to be part of Froyo - now I have couple questions about rooting and unrooting.
1. is there a way - other than unrooting phone - to install official HTC 2.2 update when it will be available?
2. will I be able to install new firmwares to rooted phone?
3. If there is the way to update rooted phone, is there a way to "move" installed apps from internal memory to SD card?
4. If I need to unroot the phone, how will I know which RUU should I apply?
I bought mine Desire unlocked at TELE2 carrier in Croatia.
Thanks in advance.

Samsung i5800 first instructions

Hallo everyone!
I am new to this board and i have a few questions.
I recently bought a Samsung i5800 with android 2.1. Unfortunately i have problems with the pin requesting (i read in forum, that this is a known issue, my provider seems to use a modified firmware, that causes the problems).
So i want to update my mobile because people in forums say, that this is fixed by updating to samsung original 2.1 or 2.2
However I read, that I should make a backup, before I do so.
So please can you give me instructions how I should start(with links)?
And do I need to root my phone? to do upgrading or to install an official firmware?
And how do I unlock my mobile for all sim cards?(In my Country Austria it's absolutely legal to unlock the sim card).
And shall i first root it and then upgrade or upgrade and root it?
And how do i do a backup without rooting?(I want to have this current system as backup, for warranty issues).
If possible, i want to do an upgrade without rooting.
Thanks for the answeres.

[Q] ZTE (Telstra) T28 rooting

Hi, folks.
I do apologise if this is the wrong place for this - so many forums to choose from!
Earlier today I bought a ZTE (Telstra) T28 phone to replace a damaged Samsung Galaxy Ace, as they have pretty much the same features.
What I forgot, though, is that I had rooted the Ace, and installed a custom ROM. So despite the same features, I'm a bit uncomfortable with the T28.
I did notice that its features are similar to the ZTE Blade. This is probably a long shot, but does anyone have any information on whether I may be able to root it using the same method and files? Or at least if it is possibly to ATTEMPT the rooting method, with a means to identify if it isn't going to work/back out without waiting for the phone to be bricked?
I did install Ask Mr. Pigfish and it suggested I was using a Gen2 Blade, but I suspect that it was simply identifying that it was using the same Android version. (Kernel? Am I using the term right?)
If it helps, when using the usual Android "Check for updates" option in the menu, it tells me I can copy an update image to the SD card, and can update from that menu.
I'm quite happy with the phone; I'm primarily wanting to root and update not for update's sake, but to remove the pre-installed apps. The device is exclusive to the Australian Telstra provider, but I am not a Telstra customer. I am using a different provider that resells the network, so the installed Telstra apps do not work for me and take up a lot of the device's tiny space.
Cheers and thanks in advance for what I'm sure will be a lot of useful info!
Hi and sorry for the grave digging but I really need some info about rooting the T28. I'm completely new to rooting and would love to find a one-click-root or something but no such luck. Has anyone rooted this phone successfully? I'm stuck with this one so hoping for a positive answer

[Q] Unroot phone with upgrade - Galaxy S Relay 4G

Hello,
I buy a Galaxy S Relay 4G, I first unlock the phone following this thread http://forum.xda-developers.com/showthread.php?t=2255892, root with this thread http://forum.xda-developers.com/showthread.php?t=2787068 install clockwork and make a backup, i use one time this backup and it works fine.
My problem is one day my phone ask me to upgrade to another version of rom... Cause i'm afraid it lock again the phone, i decline, and then he ask to upgrade everyday, and one day, i "missclick" and then the phone reboot and began to make lot of operations.
Two times he ask me to flash the rom and i say no the two times, then he start again but clockwork was removed, root removed, and the phone is on the same version...
Since then, he doesn't ask me to upgrade, but i canno't root the phone with towelroot... I doesn't understand why...
My phone has some lags so i want to revover my save...
My questions are:
- Can I reset the phone to reroot him ?
- It seems that i can make the upgrade keeping my phone unlocked, is it right?
Thank you

[Q] Will a brand new Z3 be still rootable ?

Hi,
im looking at buying a Z3 at the weekend but the main thing is will it be still rootable? Im not sure what firmware it will come with
Are all versions still able to achieve root?
If so could someone link me to the best root method, much appreciated
I've bought a Z3 3 weeks ago and it rooted just fine. You do need to flash an older firmware

Click to expand...
Click to collapse
5.0.2 isn't rootable, at least not directly.
As long as we have root method for at least one fw available for device we can root all new firmwares.
So...it's not a problem to root Z3, no matter which fw was on it.
All you need is to downgrade to 4.4.4 (version that could be rooted), root it, install recovery and then upgrade by flashing prerooted ROM.
Z3 will retain root possibility as long as its alive...
Of course, all of that applies for locked bootloader.
If you want to unlock bootloader, you could root device by flashing kernel via fastboot...

thanks for the help, phone is coming tomorrow so it will be the first thing i do.
Coming from a nexus 5 so should be quite an improvement, especially battery life.
Another Question
is app2sd built into the firmware? or do you need a third party app which requires root?
things i need installed on SD card:
all games / apps including titanium backup PRO
can it be done?
If you get a new T-mobile Z3, you will not be able to root or unlock the bootloader.

Rooting Galaxy S6

Hello, I'm new to the S6. I have a couple of questions to help me decide if I should root or not. First, what are some of the main advantages to rooting the S6 specifically. In the past, I've rooted phones mainly to write directly to SD cards. Being that the S6 doesn't have one, what are some of the advantages to rooting this phone. Second, I know that if I root, OTA updates will be disabled. I have the Verizon version. How do I go about getting those updates? Do I need to install a custom recovery?
