A few questions

Hello everyone,
I just got my Droid Incredible and have rooted it using Unrevoked3. I'm really enjoying it, but I have a few questions:
Am I correct in thinking that rooting consists entirely of getting su and Superuser.apk on the phone, and the hard part is setuiding and chmodding them?
What exactly is meant by "radio" in "flash a new radio"?
Why is it necessary to flash the stock recovery before applying an OTA update? Shouldn't ClockworkMod be able to do anything the stock recovery can?
(Somewhat related to the previous question) What would happen if one accepted an OTA without unrooting or applying the stock recovery?
Thank you all and sorry for my noobishness.

1. It also consists of replacing the stock recovery with Clockwork. It's ridiculously simple thanks to the unrevoked tool.
2. Radio = Baseband.
3. No, Clockwork cannot currently flash the radio.
4. I doubt anyone could answer for sure until it comes out

Thanks for the quick responses.
I'm not trying to criticize Clockwork in any way here, but why can't it flash the radio? Does it need the NAND to be unlocked, and if so, would it be possible to use Unrevoked to put on a new radio?

1. Root consists of getting the MOST access to the device so things that we're normally out of our privilege range can be accessed... i.e. flashlight/titanium back up etc. It also pushes busybox su and the custom recovery to make ADB easier.
2. Think of the radio as the bios on your PC....very important...mess with it and you can EASILY break your machine of choice.
3. The reason I am sure Koush left radio flashability out is because of the ridiculous amount of noobs that would simply destroy their device by being curious/not reading the giant red letters in most posts/just not paying attention to what they are doing. It is VERY easy to brick a device with access to flashing the radio...dangerous and probably a fail safe to keep as many bricks down as possible.
4. What would probably happen with the OTA is you will either A. Loose root and be completely stock WITH NO WAY of downgrading to gain root. B. Brick Brick Brick. C. Profit? D. It might not let you even continue with the installation because of the custom recovery...not sure though because it hasn't happened yet....just DO NOT ACCEPT ANY OTA REQUESTS.
The PB image is the only way to downgrade back to stock. Completely stock. Out of the box stock. No root...no nothing! BUT it reopens the unrevoked exploits so you can reroot and also allows you to flash the OTA is your version is older...some tricks need to be taken though to get your version older then the ota.
The OTA is said to patch the exploit to RUU to stock. That means no mores roots if you OTA. Wait it out...when it drops it will be rooted and ready for the flashness.

Gingerbread update OTA update and rooted question

So my wifes phone is rooted with s off. When she receives her update will she be able to update and then I can just reinstall Su and CWM correct?
Thanks
Sent from my DINC using XDA Premium App

CWM will stop your phone from updating from the OTA.
It downloads fine, but when it tries to reboot to apply the update it looks for the stock recovery. You'll need to go back to stock recovery before you update.

Going back to stock requires that you use the RUU found here which will bring you back to stock recovery correct, but you will still retain S-OFF.

Running the RUU WILL keep S-OFF. But on dougpiston's site there is also a stock recovery you can flash in hboot if you don't want to run the RUU. I haven't used it though. So I can't really say anything about it.

That should work, S-Off/S-On settings are only changed by Unrevoked apps.
The RUU should restore your bootloader, OS, and recovery back to factory.
If that doesn't work, I use the zip files off of dougpiston.com to recover my phone.

Final question. If I apply the RUU will it wipe her phone or will she retain all her apps and such.

The RUU will wipe EVERYTHING! It takes it back to factory settings. Out of the box. Minus S-OFF anyway.

I have a ROM Manager restore point with stock froyo, but rooted. If I restore to this, will I be able to get the OTA gingerbread update?

Why do you all want to receive the ota? Just wait until a devs gets it and makes a rooted flashable zip. Updating the ota will s-off and make you unrootable. Then your gonna be stuck with the crapware Verizon tries to force down our throats. The will be nothing special with the ota except the 50 mb of wasted space for crapware. Just hold on to your shorts and let the devs do their work!

[q]remove clockwork recovery

is there a way to remove clockwork recovery? my wife's phone has s-off and recovery, but she wants to keep it stock and use the OTA upgrade.

You should really check this thread:
http://forum.xda-developers.com/showthread.php?t=1161411
I just flashed this over my stock froyo. Worked flawlessly, didn't lose any apps or anything. Removes all the VZW bloat and runs perfectly.
One thing to note, I believe you'll have to manually update your radio to the newest version but it's no big deal.
You can find the newest radio here:
http://forum.xda-developers.com/showthread.php?t=1134451
From what I've read the radio that comes with the OTA is 20.27W.30.0811U_1.09.01.0622 unless someone can tell me I'm wrong.

i know all about that. but i still would like to know how to go back to stock recovery if possible.

You'll have to reflash the RUU and overwrite CWM with the stock recovery image once more.
If you don't mind me asking is there a reason why?
The only way I'd even consider doing this is if you're going to return the phone or if there's something wrong with it.
Why not just flash the official OTA that RMK put together and then flash the new radio?
It's EXACTLY the same thing minus the verizon bloat apps, heck it even runs faster than the stock OTA.

Do you flash the new radio like you would a new rom?

No, There's a certain way you have to do it. Pretty easy BUT you have to check the MD5 to make sure it's not corrupt, otherwise you'll brick.
put the P32IMG.zip file onto the root of your sd card. Boot into hboot by holding vol down and power on startup.
It'll search your sd card and then ask to update. press power to update. It'll reboot when finished.

The issue is that if you flash the new OTA you'll lose root for the foreseable future. Currently most are unsure if it will undo the s-off and in the process you may lose the ability to root until a new exploit is found.
Read the first thread that is stickied on this forum about the OTA.

There's an app in the android market called AFV (android file verifier) that allows you to check the md5 sum of files you download directly on your phone. I would suggest you install that app and make sure the md5 matches the radio file you downloaded before flashing the radio as changing radios has much more potential to brick your phone entirely that traditional rom flashing.

this is for my wife's phone. mine is running CM7. my concern is that if i go forward with a rooted gingerbread, i won't be able to return her to full stock recovery and rom later. i don't want to do anything to her phone i can't undo later. is there a path for that after upgrading to the rooted stock rom?

Of course, it can always be undone later on. However, if you do the OTA update then you will not be able to root until a different exploit has been found.
This is why we're trying to get you to go the route of the rooted stock rom.
Just follow the directions in the first 2 posts of that thread and she'll be as stock as she got the phone (Minus having root, it being faster, etc....)

what's the rollback if we want to go full stock. no root, no CWM - stock enough to send to verizon.

I understand about the wife issues. My widest inc2 arrives in a few day. My plan is root and stock debloated Rom for her. She won't even know its not stock. That way when she wants sense 3.0 I can give it to her. If she knows I never hear the end of it.

Why are you unrooting his device? If it's to get the OTA 2.3.3 update, wouldn't it be easier to flash a rooted stock froyo rom, go to the system update setting and then update? Of course, I'm assuming that is what you're trying to do so forgive me if I misunderstood your post.
posting & replying via my EVO 4G

Ok, sorry for not being very informed. He tried to update to the ota but it failed. I assumed that it must be because the s-off since he hadn't done anything but tether.
He really has no need to be rooted because the only thing he wanted todo was tether. Now, I have turned the s-on, but the pc36img fails to update.
Is it safe to just check for/install the system up? Or does the phone need to be unrooted?

If you already have S-On, all you need to do is flash the ruu that coincides with software 3.70 or 3.29. You can download any of the ruus for the EVO by clicking on the RUU link in my signature. Also, there's a link to rooted stock roms in my link, as well.

Awesome! Thank you very much. I'm on my phone now, so I'll check it out when I get to my laptop.

Before you do something you will regret, go back and use unrevoked asap. Get back to S-off. If you turn S-on, and then take the update, you can not go back at the moment.

Honestly, my bro-in-law doesn't need root. Here I am trying to fix his problem. I've spent more time on this than I should. I mod my X, but the evo confuses me some.
Are you saying he can take the ota rooted, with s-on?

You need S-Off for permanent root and ability to flash custom ROMs. So before you take the OTA for him, as long as the phone is 2.2, run Unrevoked once again and install AmonRa.
Does he even like Sense? I would suggest trying one of the setups from my sig, or even MIUI if he doesn't need 4G.
You could have S-On and get the OTA, which would make his phone unrootable and boring, or you could just root back and flash a ROM with better battery life (I hear that Calkulin's works great, but so do other ROMs)
Before you do anything, try showing him pictures of MIUI, SalvageMod, MikG or another ROM and ask what he likes best.

Oh, and he would need a custom ROM with tethering unlocked for the ability to tether for free. And he would need S-Off to put that ROM on.

I understood from your earlier post that your brother-in-law didn't need root and thus the reasons for the answers I gave. Yes, he can accept the OTA while S-ON and he will indeed upgrade his device to 2.3.3, however, should he wish to unroot afterwards, he won't be able to until an exploit can be found. I take it your friend isn't the type of person who flashes roms, mods, kernels and such.

check your hboot version and S off status
if its hboot 2.16 and S on, you are boned since you unrooted it when you took the gb update
so basically...dont tell your friend that you screwed his chances to root yourself lol
the correct route would have been to flash with a rooted stock GB ota wich was already out there, but its too late now : /

I really appreciate everyones help, don't get me wrong. However, I'm sitting here doing all this research and trying to get help for my in-law who thought he needed root and wanted to tether. He doesn't even use tether. I'm not showing him any custom roms. He lives three hours away and i'd be doing all his leg work/fixing his problems.
All I want to do (and him as well) is get him to gb stock unrooted and be done with his phone.
So, if the s-on is on, but the su app is still in the app drawer, and the pc36img.zip failed. If he selects settings>about phone>check for updates, will this get him to gb?

Which zip would not flash in recovery?
The only zip you will flash in recovery is team epic root from recovery. And it must be flashed in the recovery that was installed with Odin.
If you let the phone restart after flashing recovery in Odin the custom recovery will be replaced by the stock recovery.

As a TOTAL noob: appreciate the easy explanation! Waiting to do this myself, but have a few quick questions first. I've done a lot of reading up on rooting but I'm still not entirely clear on a few things so I'm hoping someone can explain it to me like I'm five:
1. Can I accept over-the-air updates from Sprint on a rooted phone? i.e. when they push Android 4.2. If not, do I unroot and reroot to update? Do I have to uninstall everything?
2. Is there something I need to install after doing this? I previously rooted an HTC EVO and remember having to install Superuser immediately after. Anything similar here? Looking to ultimately run wifi tether so any advice toward that end would be greatly appreciated.
3. I'm a little confused about rooting/flashing and some basic definitions. Are they the same thing? I hear a lot about CyanogenMod - what is it and is it coming into play here?
Thanks so much!!

This is not going to be a straight up yes or no answer. If an update comes ota to your phone, you will be able to receive it providing you:
1. reflash stock recovery before accepting it.
2. haven't flashed a custom rom
3. haven't removed any required software. The ota will look for certain software and files. if the required software and files aren't present the ota will fail
None of this should concern you though. There are ALWAYS ways to get the updates while being rooted
2. Is there something I need to install after doing this? I previously rooted an HTC EVO and remember having to install Superuser immediately after. Anything similar here? Looking to ultimately run wifi tether so any advice toward that end would be greatly appreciated.
These instructions seem like you are doing many things. You aren't. There are really only 5 steps. I just broke all the steps down in detail. Really all this is:
1. Downloading all the files to your computer
2. Installing your Samsung Drivers to your computer
3. Copying one file to your phones sd or external sd card. (Team_Epic Root_From Recovery)
4. Flashing CWM Recovery to your phone with Odin.
5. Flashing TeamEpic-Root-from-Recovery-v5.zip with CWM Recovery
The Team Epic File that you are flashing in recovery installs superuser, busy box, and in addition removes two files needed to make recovery stick.
3. I'm a little confused about rooting/flashing and some basic definitions. Are they the same thing? I hear a lot about CyanogenMod - what is it and is it coming into play here?
Rooting is really nothing more than giving you the user, the right to access root or system files. It has very little to do with flashing as you can flash updates with stock recovery.
Flashing is simply installing something in a tar, img, or zip format. tar files are flashed with Odin, zips are flashed from recovery and img files are flashed or pushed with adb (Android Debug Bridge)or fastboot.
Cyanogen is a rom. roms are very simply the phones operating system and user interface. They're called roms because their files are kept on read only memory. There are many roms out there for our phone.

Awesome, appreciate the prompt response - thanks so much!!

Thanks!
Thanks for putting this together. My new gs3 arrives tomorrow and I have already prepped my computer with your files in anticipation.
I'll report back how it works out.
Thanks again!

One more thing
When I do get my phone should I activate it first or root it first or does it matter?
I know it voids the warranty but I guess I could unroot to take it in for service if needed?
Thanks again.

I would activate it.

This works with the 4.1 update, correct?

I previously had the Galaxy S1 (Epic) and went through several custom ROMs before finally going back to a stable release with root because of dissatisfaction with the ROMs. My phone never really returned to perfect functionality after this experimentation, and always had some buggy glitches and many FC's. Now that I have a perfectly running GS3 with Android 4.1, I would love to be able to wifi tether and install apps like adblock and Titanium Backup Pro, but I am hesitant because of my past experience.
Do you think there is any reason at all that simply doing this root procedure would change the functionality of my perfectly smooth-running GS3?
