Download http://forum.xda-developers.com/showthread.php?t=884093 and nandroid restore.. OR before you flash a custom ROM just do a nandroid backup.. then restore to that and you're back to stock.
Nandroid backup/restore is available in Clockwork Recovery (ROM Manager on the market)

[Q] Nooby Question Regarding Perm-Root

Hey guys, sorry for the nooby question but I just s-off'ed by TMOUS HTC Sensation 2.3.4 OTA and installed CWM 5.0.1.0, and I was wondering if i should follow step 3 on the official noob guide for rooting in the dev section regarding the perm-root. It says to flash a .zip through my SD so as to not lose root when rebooting, but I have already rebooted my phone multiple times and not lost s-off or CMW. Is there something that I'm missing or is this step old and unnecessary? I would greatly appreciate any helpful replies!
*resisting the urge to facepalm*
It looks like you missed the whole temp-root-before-we-got-S-OFF-thing But to answer your question, S-OFF and root are 2 different things. Without S-OFF you can't get root

Oh well that makes more sense! Haha wow I feel dumb.. So just to be clear, S-off only allows me to gain access to system root, while rooting the phone actually allows me to flash ROMs and such, correct? If so, what should I do to root it after S-off? Just flash the .zip linked in the rooting guide dev post?

A custom recovery such as ClockworkMod you have installed is the tool that is used to custom ROMs. At this point you have S-OFF and you have the custom Recovery in place so you have 2 options:
1. Use ClockworkMod to flash the superuser; this will 'root' your current ROM and allow you to run apps that require root access such as Titanium Backup, ROM Manager, etc.
2. Use ClockworkMod to flash a rooted, custom ROM which will replace your current ROM.
In either case the first thing you should do is boot into ClockworkMod and do a 'nandroid' backup of your current ROM.
Oh ok, Thank you for the clarification. I ended up flashing the .zip/superuser on the rooting guide and now I am attempting to flash ARHD 3.0.4. with Sense. I made a NAND backup using CWM before flashing the superuser, and now I am doing a titanium backup. Should I back up my apps and system data or just my apps? Also can the free version of titanium backup accomplish this or do I need the Pro key? Sorry for the large amount of nooby questions but seeing as how there are so many knowledgeable people on this forum I figured I would play it safe. Thanks for all the responses!

Well, not exactly. S-OFF unlocks the NAND (so you can flash ROMs, install CWM,...), but root basically gives you ability to change everything, take screenshots,... (Sensation has power + home screenshot though). Custom ROMs are already rooted and you don't need root to flash them. And you can't get root without S-OFF. I hope I explained it

When you are switching ROMs, it is good practice to just backup and restore apps using titanium backup. If you backup system data from one ROM and restore it on another ROM, you may have issues. I have always used the free version.
Awesome, I really appreciate all the help! Unfortunately, I just stumbled into an issue when attempting to flash ARHD 3.0.4. I flashed the super wipe.zip as instructed and all went well, but when i went to flash the ROM itself it gave me an error saying "E:Can't open /sdcard/zips/Android_Revoultion_HD-Sensation_3/0/4.zip (bad)". Any ideas as to how i can successfully flash this? I downloaded it straight from the Dev page so I highly doubt its a bad download..
Edit: Nevermind, being the genius that I am I left the download on my computer going but it went into hibernate so the download stopped at 38MB instead of the complete 346MB..

Not sure this is the right place to ask questions - but regardless, back to Froyo stock? If so you could ODIN something from here - I believe there are some that are pre-rooted for you. You could also ODIN the EE4 tar found here (maybe include the pit file found here), then ODIN the CWM found here, boot into recovery and flash a custom kernel (like one from here or here for example). Hope this helps!

[Q] General concepts questions (root, flash, bloatware)

Hey all,
So I have been reading around a bit now and was wondering if someone could help me understand some general concepts.
my goal: I am trying to remove all the bloatware from a Huawei y300 (no carrier) and put stock android on it.
From what I have been reading, it sounds like I need to first unlock the device, then root it to get access to superuser. Then what? Can I just use the superuser to remove the bloatware? Or do I need to flash it all and install a custom ROM?
Also, I should prob back the whole device up first so that if I mess it all up I can still restore the phone to the way it was when I got it from the distributor. Is that easily possible, or are there risks associated with that? If I mess up the phone real bad is there a big chance I will not be able to get back to its original state?
Now the details of how to do all this are burried in the forums, and I will figure all that out. I am just confused about the order of things a bit. So if anyone could give a high level explanation on the order of steps and the need for each that would be awesome!
Much appreciated, and thanks
The basic process is unlock the device, root the device, flash a custom recovery, flash a custom rom. Flashing a new rom is what will remove the bloatware for you, and you can find a stock android rom that will literally be the barebones version of android. Rooting the device allows you access to flash the custom recovery, which is needed to flash custom roms.
Everything as said above, with a nandroid backup added as soon as u flash the custom recovery is recommended.
BTW there are chances that u can brick ur phone if u don't follow the custom rom flashing instructions properly.
Anyway the nandroid backup will help u in this case.
In case if the nandroid backup even fails, which means there is a heavy mistake also there are very less chances of it to happen, u can try flashing the stock firmware.
Hit thanks rather than typing it
Got it thanks!

OK so I unlocked, rooted, installed TRWP recovery, and then used that to back up my phone. From what I read online it looks like backing up with TRWP is the same as backing up with Nandroid. I'm prob just not getting it, so wanted to ask what is the significance of Nandroid? Why do both TRWP and Nandroid?
