Hello Everyone,
My Nexus 7 is rooted and was running AOKP.
I decided to find another Rom to try out and downloaded one using ClockWorkMod.
I rebooted into recovery and did a full wipe, then I installed the Rom.
When I clicked reboot a message popped up but I was not able to read it entirely, it said something to the effect of "flashing this rom will overwrite........" and I didnt catch the rest.
I tried to hit "Go Back" but the N7 rebooted into the new Rom.
It was basically a stock rom so I tried to boot back into recovery and CWM was not installed.
I downloaded it from the market and could not boot into recovery.
So, I downloaded RootChecker and it said that I did not have Root Access.
I ended up having to use the N7 tool kit to re-root my N7.
My question is, how did I lose root access?
I am assuming that the rom I installed was basically a stock rom and that is how I lost root access but I am just not sure.
Have any of you experienced this?
Any thoughts on this?
Just curious.
I apologize in advance if this has already been covered somewhere else, I did search for it before I posted.
Thank you,

OK, for starters:
Tablet's current stats:
ROM: CWM-Rooted_Acer_A500_7.006.01_COM_GEN2
Recovery: Stock US 1.141.07_COM_GEN1
Root status: Rooted
Problem at hand: Cannot install OTA updates. I used Acer Recovery Installer to originally install CWM so I could flash ROMs (duh). So I used Acer Recovery Installer to have it install the stock recovery image so I could actually install the OTA updates. I know this likely means I would lose root, and that is OK.
When I installed the stock recovery back, I tried to let it install the update. It would reboot, show the package opening (little box that was open and a progress bar showed up). The bar got about 25% completed, then it changed into a triangle with a "!" inside it, and the little Android dude below it. After a few minutes, it would reboot by itself. Once booted up, I would get a message that simply said "Update Failed".
I brought this up in another thread, and someone suggested I unroot as well. I immediately tried to do that, but IconiaRoot gives me the following:
Removing superuser.apk
Removing /system/xbin/su
Sleeping in 5 seconds...
Something went wrong.. you are still root?!?!
I can confirm I am still rooted by going into terminal emulator and running su and I get a # sign. So I am at a loss now on what else to try. With the stock recovery, if I tell Acer Recovery Installer to reboot into recovery, when it reboots, all I get is the triangle with a "!" in it. I noticed the ROM has GEN2 and my stock recovery has GEN1, and the OTA update ends with GEN2, is that an issue?
EDIT: I also know now there are other rooted ROMs with these OTAs applied. I'd like to unroot and go back to stock, so please do not recommend this.
Ok did you make a backup via CWM ?
In the other thread the recovery i restored was the backup i made of my one via Acer recovery,
If i was you i would reinstall CWM and make sure that recovery is working then wait for someone to come in and tell you the correct stock recovery for your one is.
oh i get u now, u got the gen2rom installed and u want back to your own stock gen1 to get the OTA, correct?
u need a cwm backup of 3.2 gen1 stock, when u restore it, u should receive an OTA notification for the 3.2.1 GEN1 OTA. Before you download it, u need to be rooted, use the backdoor/OTA method of timmyDeans. It will create a backdoor so after you have installed the OTA you can get in to run the installtools command again to root and install cwm again. AND you will still recieve OTA's.
Iconia Root - only works on 3.1, it will not work for 3.2, so it will throw an error.
But i'm sure root wont prevent the install as the OTA overwrites system files and resets the permissions, it also checks all system apps are there, so if you;ve deleted any bloatware or changed build.props the update will fail.
I have spent the last week trying to get back to stock so i can OTA. I have read hundreds of posts and tried all the methods that had been posted. The easiest and quickest and most successful way of achieving this was the backdoor method. Yes you need adb installed but you dont actually use it, it is all done for you. there is a very good walkthrough here http://www.chdcomputers.gr/en/mnu-kb-en/mnu-kb-android-en/mnu-kb-android-devices-en/mnu-kb-android-a500-en/254-art-kb000005-en
Then install the backdoor v3 (link in sig) -have a look and see if that will get u to where u wanna be!
Decideed it was easieeer to just install one of the prerooted roms from the dev forum. Running 7.014.14.com gen 1 now. Thanks guys.

Here I did it before and I never got a message says root access has been lost.
1. Odin it back
2. Root by using causal method
3. When phone reboot itself into recovery TWRP
4. Don't back up just reboot into welcome screen
5. It should ask you to install superuser, just install it
6. Finally, reboot into recovery and make nandroid back up.
On step four, I back up by using nandroid before superuser install. When I change rom, message always telling me I have lost root access quite often this way.

thats usually what i do, i tried 4 times. It doesnt ask me to install su, its already installed.
i might just have to update and wait for new root method.
Download a superuser/supersu zip file and flash it through your twrp/cwm recovery and reboot.when I first rooted my I337 ATT S4
It would loose just as I would enter recovery and my recovery would ask if I wanted to fix it before rebooting. After flashing the supersu zip file
I have had zero issues with root.

Hey guys I'm new to android had an iPhone for 6 years. Just got the gs4 two months ago. I rooted the phone took out bloat ware apps using titanium back up. Have a few other rooted apps. Got Interested in ROMs and kernels so did some research looked around on here to how to do it. I downloaded infamouses newest ROM. I have ROM manager and I downloaded cwm recovery through the Rom manager. When I go to back up my current ROM and everything it boots into recovery mode but it isn't cwm recovery. The emblem doesn't come up and I believe its the stock recovery. My question is how can I get the cwm recovery so I can back up my current ROM and then wipe it and install the new one. I'm new so sorry if this is easy or anything I appreciate all the help
Download goo manager and let it install twrp then just flash cwm thru twrp . Or keep twrp and remember to flash loki doki if needed.
Wait!
What firmware is your phone currently on? MDL OR MF3?
If MF3, stop now. Do not flash anything.

Okay I figured out the problems. When I hit reboot and superuser is supposed to grant root permissions an error comes up saying superuser has stopped working then goes into the stock recovery mode. The only thing I found with MDL in it was the baseband version 1337UCUAMDL
Your safe to continue flashing custom recovery on MDL Baseband

Going on the information you have given, if you are doing right and using the correct version for your phone, GooManager and TWRP should be working for you. However, if you go to the development section and look for OUDHS CWM recovery, directions are given in the OP about how to manually install that recovery. Again, directions are in that thread about how to do it. I do hope you are reading all of every post that contains something you are trying to do (in other words, if you use OUDHS, read the entire thread first). Good luck.

Hey thanks for the help. I got twsp recovery through goo manager and worked perfectly. I'm having such a bad experience trying to install this rom. I went into the recovery mode after backing up my current rom and system. I wiped everything out then went into my sd card amd installed the zip that is listed in the infamous page in the developers part. I hit install and then said I'm not rooted and would I like to install superuser. I slide the thing and then went to reboot and now has been stuck saying samsung and custom with an open love under it. Pulled the batter went back into twsp and tried to reboot and still stuck. This is all after I thought I installed the rom already and nothing changed except wiped my phone. Can anyone help

Are you installing loki doki after the rom ?
Hello, first time poster. I recently tried rooting my phone using CWM method. I'm running sph-l720 with software version vpaumf9 and android version 4.2.2. I installed CWM (this version SPH-L720 OUDHS Recovery) with odin with success. Then flashed SuperUser v.099. Everything went smooth until I opened up super user and tried to install binaries and it says "Install failed". I'm wondering if I didnt have the wrong beginning firmware and i needed to (but didnt) install that pre-kernel. I'm also wondering if I have to download the original firmware and have to flash to stock in order to "unroot" even though I didnt finish the SuperUser process, or is their a way to delete the super user app and try to install it again using the same CWM i have already on the phone. I hope this isn't confusing. I'm not a complete novice to rooting, but no expert. I rooted my galaxy s2 but went to Iphone for a while, but now I'm back and a little dissapointed with myself at this fail. Any suggestions? Do i have to go to stock first? Was I using the wrong files for my initial firm ware and need the pre kernel? Am I blabbering on? (yes) Thanks in advance.

Grap CF-Autoroot from here
Follow the instructions here:
Boot back to phone. Open up SU and update binaries.
Then
Go to Playstore and download/install GooManager
Open GooManager and then press the 'menu' button (capicitive button next to Home Button) and choose to install recovery (I like TWRP).
Then let it do it's thing.
If you'd like a real easy way to get 'into recovery mode' from the phone I use the Quickboot app
Also make sure that if you are going to flash ANY ROMs you follow the instructions the developer suggests - many suggest specific recoveries be used

thank you! do i need to do anything before i do this? (Like using odin to revert back to stock?)
i ask because i already have CWM installed
I did the auto root, and open SuperSU and it doesnt ask to update binaries...does that mean it is already done. I didnt find the option in the settings.

As long as your on some kind of TW/Stock based ROM you should be Okay.
However if you want to go back to straight (AND ROOTED) stock you can use one of rwhilco12's 'one-click' restores.
The one click downloads as a zip. decompress and then run the one -click. If you've never run a oneclick read here
It will give you a stock ROM, rooted, MF9 Modem, Stock recovedry, and Stock kernel. You'll then have to use GooManger method to get custom recovery.

man thanks so much. so i definitly got super user access. I'm about to do the goo manager. since you suggested the twrp i think i'm going to try that. since i have CWM recovery installed, do u think that will create any issues if I go to install TWRP from goo manager
actually i googled and it seems that goo manager will seamlessly overwrite cwm. sorry for the questions before searching. appreciate the help. i almost didn't come on here, which would of lead me to reverting to stock, doing cwm again, then being upset that i needed twrm for most roms lmao. I owe u one. If u ever need to learn how to make bad decisions, just shoot me a pm. I got u covered.
No it will just replace it.
I actually (and many around here too) prefer TWRP 2.5.0.2.
You can download the zip for that here, boot to recovery you have now (CWM) and then install that. Or use Goo to install lates TWRP and boot to recovery and then install zip and choose the 2.5.02 you downloaded and then save to your sd card
scratch what i posted here. I ended up having to download ROMmanager and update CWM, then used CWM to install the zip you provided me. thanks so much man. Do you have a favorite stable ROM you recommend using TWRP. I value your advice

Glad you got it.
As for ROMs you really have to try them out for yourself. There are some really great TW ROMs ; Sacs, negalite, triforce and others. For CM/AOSP there are a whole bunch to choose from. I mess with just about all of them. But my daily driver has to be one hundred percent working and reliable so for that I'm usually on a stock debloated and modified TW ROM. Take some time to read through the OPs of the devs and just as importantly through the follow up posts to see what works what doesn't ahs how to fix or get what you need.
Good luck

Try this Rom!
http://forum.xda-developers.com/showthread.php?t=2327692&page=43
works great!
I hope this is in the right place, and im probably the highest level of noob at this so im sorry if i dont get all the terminoligy right
A few weeks ago, i decided to try and root my phone (after seeing that i could connect my usb to it) and had attempted to install philz custom recovery (6?) and install superSu and a custom ROM.
I had failed this and got it stuck in a boot loop (i think i may have done it twice by accident xd) and then my brother had done his magic and put cyanogenmod on the s5.
I just tried to install the same superSu zip. file that i used last time (i thought it should work) but now its telling me there is no Su binary or something, it also appears not to connect to the internet.
I guess my questions are, what did i do wrong?
how can i fix it?
what should i do next time?
Cyanogenmod is pre-rooted, you simply have to enable it from the developer options. SuperSU is not required.
That being said, if you had flashed an official SuperSU Zip through recovery, it should have installed the binary as well, so maybe your Zip is not right?
Official download here:
https://download.chainfire.eu/696/SuperSU
To fix it, re-flash cyanogen or some other rom. Possibly re-flash your modem too if cellular isn't working.
Next time, leave it to your brother to mess with things lol

so i dont need to download that file atall, if cyanogenmod is pre rooted? i did go into the recovery and only clicked install (was i meant to clear the cache partitions?).
what is pre rooted? i went to download the root checker and it told me that my phone wasent rooted, i said to my brother so do i not need supersu, he said yea u do if u want to root it (so i just went into the SD and redownloaded the one before, but now its telling me that it wasent rooted).
and what happens if i reflash it? will it just get rid of supersu to how it was when my brother gave me it? or will it alter some other stuff aswell

When you re-flash it will go back to being fresh/clean
No, you don't need SuperSU. Cyanogenmod comes with root built-in. Read below.
