I did the "Casual" TWRP Recovery and Root for my AT&T S4 and love it. I booted into recovery and flashed a backup image of my stock device and saved the 3.56 GB nandoid file on both the internal and external SD and put another copy of my original phone image or nandroid or backup or whatever flavor you want to call it, on my PC.
I've frozen 37 phone functions with Titanium Backup and dodged a bullet. I heard there was another over the airwaves update from AT&T a couple days ago, and I am pleased to see it never appeared on my S4. I couldn't be happier. I have yet to try any custom roms as cyanogenmod doesn't seem to be getting any love lately, plus I would not want to give up the universal remote in the on board "watch on" app.
Why do you want to undo TWRP custom recovery and lose root? Titanium Backup needs root. Did you flash a custom rom without going into recovery first and making a backup of your stock handset once you got root and TWRP?
In any case I think there is an Odin thread you need to read: http://forum.xda-developers.com/showthread.php?p=40976805

well.....Theres nothing wrong with TWRP recovery and root, its just that I have no need for it. I have tried a few custom roms and none offer battery life better than that of the stock TW software so I decided to just stay stock. As you said like 2 days ago at&t rolled out another OTA, however I dont think my phone installed it. It booted into TWRP and it started installing a zip. I wasnt sure if that was the OTA or not. I just dont need the TWRP and root as of now and its kind of a hastle in my current state to flash the new OTA's instead of having it automatically install via stock recovery.

I had to bring my virant to the store for warranty for, so ofcoarse i flashed it to 2.1 update 1 w. Odin. Everything went good. I came home and wanted to obviously re-root and flash a rom. Well i used 2 verisions of one click root (im on a macbook) i first go into recover because 1 click root wouldnt take e there, while in revocery i it root, then reinstall packages, it takes me to CWM. i click reboot system. and now i look on the phone and no root access but i have CWM? Would i just be able to just download the zip to my sd card, use CWM (even through im not rooted) and flash the rom that way? ALso i want to know why this is happening, ive rooted 20+ times no problem
yes i do that all the time. the custom roms come pre-rooted.
So I rooted a couple of days after I got the Tab, left the Stock Rooted Rom and then loaded the Honey Villian Kernel for O/C purposes. Since O/C is the only thing I do with Root, I am thinking of going back to Unrooted.
My question is, in Iconia Root, if I hit the Unroot with the Custom Kernel still installed what happens? or since I do not have a copy of the original Kernel, how can I reinstall it before Unrooting?
Build is Acer_A500_4.010.13_com_gen2
Current Kernel is 2.6.36.4 Honeyvillain- 1.0+
Thanks in advance

Did you not backup using CWM before flashing your custom kernel?
If you made that mistake, all you need to do is get the stock kernel from the build you're currently on, create a CWM flashable file and flash your stock kernel back.
I did make a backup, then screwed up and wiped the External Card it was stored on. I know, such a newbish mistake. Since then, I have other Backups, just not one with the Original Kernel.
thanks a bunch.. will see if I can search out the kernel I need.
Just grab one of the stock 3.2.1 roms in the development section and install it through cwm. That will replace the kernel, then run acer recovery installer from the market to return to stock recovery. After that you can try running iconiaroot to remove superuser or you can just uninstall it from settings/applications. Now you should be good to go.
Here is a link to a non rooted latest version. It installs through cwm. http://forum.xda-developers.com/showthread.php?t=1429199
The problem is, cwm will still be on your tablet so you will have to flash the stock recovery. I don't know where you can get a flashable version of the stock recovery without using Acer recovery installer which of course requires you to be rooted to use. Although the advantage to keeping cwm will be you can still flash a custom rom in the future the disadvantage would be you won't be able to take OTAs because they will fail when the don't find the stock recovery.
So even if I successfully Unroot, I will not be able to take OTA's?
I have the kernel and was just going to flash it back, and Unroot. If I cant take the OTA's then it's not worth the effort.
Thanks for the information.. My tablet is fine the way it is, just figured if I wasn't really using root, I would go back to stock. Not really interested in flashing a Rom as I don't want to reload all the apps and set it back up.
Thanks again, as usual you guys are quick and helpful.

@Alteros - What I am about to say is NOT recommended by 90% of all posters so I expect there to be replies urging you not to do this - HOWEVER - if you install a custom Rom then just wipe the following (1)Cache (2)Dalvic Cache (3)Battery Stats DON'T wipe DATA. When you format just format the following (1)System (2)Cache (3)Flexrom DON'T format DATA.
By doing this you should get back all your Apps. There is a possibility, as other posters will tell you, that you will screw up the new Rom and then have to jump through hoops to get back to Stock. But if you want to take the chance and it works then you will have your new Rom and retain your Apps.

yeah that might work, but he may just to get titianium backup and backup all his apps, if he is going to revert to stock, by flashing a stock rom over a custom rom things might act funny and since he is not rooted only thing he can do is wipe the device and start new
his less headache way of doing things is to leave root and recovery, and use a stock rom. Theres alot of tegra devices out there and who knows how long this community will be kicking out updates long after acer closes support for A500
Thanks to everyone that helped. I ended up loading Thor's 14.2 over the weekend, was not nearly as painful as I thought it would be. So I may try more in the future.
You guys are always quick to respond and helpful.
What I think I learned is that, once you root, you can never go completely stock again. Since there is not a way to get rid of CWM, at least not easily.
Bought the Verizon G2, brought it home, rooted it. So basically I have nothing but Super Su and a crap ton of bloatware haha! Any threads showing me how to make a backup of what I have now, then a tutorial on how to flash a new ROM? I just wanna be safe having a backup recovery of the phone basically all stock with root acess.

You need to Loki first to get TWRP, check the Verizon sub for details. Once you do that you can make a back up of your current phone. Once compete, you can wipe data and flash a new Rom safely. Fyi, the flash takes a long time, just wait it out.

I don't know what LOKI is, but if you're rooted then chose a recovery (twrp or cwm), install it, and then do a nandroid backup. Then you can flash whatever ROM or mod you want.

Pretty sure you don't need Loki...that's for devs only. TWRP is already pre-lokied for your convenience.

^Exactly. Though you should probably use TWRP.
Hello!
I have just got a new LG G2!
I want to root it, but I'm a little bit confused atm:
1) Rooting the device using IORoot does not change the kernel or recovery, does it? (I'll be rooted runnig stock and won't be able to flash stuff)
2) If I want to create a nandroid backup, I have to flash first CWM/TWRP. So how can I make a nandroid backup for my current unrooted and runnig stock phone?
3) Can I backup my EFS files without a custum recovery (with root only)?
4) Is that correct that after each rom I flash, the phone needs to be rooted again?
Thanks!
1. Yes
2. You use the cwm. Or twrp to make the backup.
3. Not sure, have always been rooted sui never looked for a way to do that.
4. No, I've never had to reroot after installing any rom.

unroot
Is there a way to unroot and leave no evidence that the phones been rooted. Im planning to return it and get another one. THanks in advance
Hye friends, how are you all? I have note 3 N9005 32GB. My phone is rooted and TWRP recovery is installed. I tried to install a custom rom but I was not able to do so. Is there anything else that I can do to get benefit from my rooted phone? Is there any other simple custom rom that is more easy to install? one more thing. What MD5 check?
Thanks.
I just get to know about nandroid backup feature. That is amazing. First time when I flashed custom rom and it went wrong. I was forced to reinstall stock rom. But now I think I can restore the backup without going through the difficulty of reflashing, reinstalling apps, rerooting and again flashing TWRP. Am I right?
with root you can write custom file to your system such as viper4andriod or wifikiller
for what MD5 is you can check this link: http://forums.androidcentral.com/optimus-v-rooting-roms-hacks/113984-what-md5-how-use-verify-your-download.html
Thanks. I now know what md5checksum is. Thanks for your help.
no prob:good:
One more thing that I learnt is how to set permissions. Feeling happy.
