Is it possible to lose root?

I've been rooted for awhile now but now every time I try to open a app that requires root it just hangs and then FCs or just tells me I don't have root access. The SU app just FCs as soon as I open it. Is there anyway to lose root? I can still boot into clockwork and flash a ROM. I read about the SU app having issues with some sense ROMs but I am on CM7, last release.

I had that problem a few weeks ago. When you rooted, did you use the 1-click or the hack kit? I originally used the 1-click, but the phone started having issues so I ended up getting some help and flashed back to stock, rerooted using the hack kit, flashed a new ROM and kernel, and haven't had any issues since. I believe there was a Superuser fix posted in the FAQ of the 1-click if that's the method you used.

Did you wipe data/cache/dalvik prior to flashing your ROM?

I used the 1-click awhile back and never had any issues. The superuser fix in that FAQ only pertains to Sense ROMS I believe. I'm on CM7 at the moment.

Yea, I always wipe prior to flashing even if it just an update. I may try to reflash latter tonight to see if that corrects it.

sounds more like a super user error. If your still having trouble try reinstalling the apk, and possibly going into recovery>advanced>fix permissions.

It let me update it from the market and now everything is good to go. Never even thought of trying that. I figured I already had the newest version since I was on the most recent CM7. Many thanks.

[Q] update 2.1.0-2.2.3 LOST ROOT???

I did the update just now and thought everything went well. This is my first time. Someone else put infused 2.1.0 on phone and everything that goes along with that. I followed the directions in beginning of post to manually do the update. Now all my root apps are telling me i'm not rooted. I rebooted, took battery out and back in. I have read entire Infused post and no one has had this issue? Before i started i went into ROM manager and made a back up first.
Not sure what to do now??

R you doweling of a OTA update or rom update I'm assuming rom. Is your supper user still available in your app drawer if so go into the setting and make sure its on. If not I recommended unbrick to stock and re-flash make you directions are followed to the T

Can i restore the backup i did before the update? Will that take me back to 2.1.0 where all was well?

Just do a reboot, all your app will work after that

I did reboot. I have NO ROOT after this update but everything else is fine. All apps are there...but my root apps say i don't hve root. I d/l root checker from mkt and it says it;'s there but the binary isn't up to date or installed incorrectly. within SU i tried updating the binary and it fails.????

Uninstall the update

ok. i uninstalled the update to SU. rebooted. all Root apps still don't work and say i'm not rooted. NOW though. SU doesn't even come on and say denied. ....

Rooted just means you have the su app and can give su permissions to apps. If apps are asking for su permissions and not getting them it's the same as not being rooted as far as the app is concerned. Go into you super user app and see what has permissions and what doesn't, try to reset the settings.

update 2.1.0-2.2.3 LOST ROOT???
Just a recap...i was rooted running infused 2.1.0 and had and used rooted apps. I did the update 2.1.0-2.2.3 infused update then all of a sudden i couldn't get into titanium backup or any of my rooted apps. every time i open one SU denies it. I d/l root checker from mkt and it finds SU 3.0 on phone but says im either not rooted correctly or not at all. it gives me a log but i can't make heads or tails of it..so , if someone could I can PM you the log. I checked my SU permisions/settings...it should work...doesn't ands won't allow a thing. How did I lose ROOT? I followed the manual instructions in post.
All of this is related to me updating to 2.2.3 infused ROM. however, i have read the eintire forum front to back twice and no one has lost root because of the update...I even tried installing busybox but it fails because it says i am NOT rooted. I uninstalled the update to SU 3.0..that didn't work.
GTG-- I PM'd you days ago asking for your input on the upgrade but didn't hear back...upgrade done...issue...lost root....any ideas??

upgrade infused 2.1.0-2.2.3
Anyone out there with an idea? I haven't heard of anyone losing root having done this upgrade. Could i possibly still be rooted but maybe a setting got messed up somewhere? a file moved??
Still looking for answers...thanks

I have been through this many times before, you can do two usually the root access comes back after a reboot, since it didn't for you here are couple things you should consider to do
1) uninstall superuser than download again from market. Or
1) flash the rom again from scratch

well, since SU came from root and is a system app and apprently i am not rooted so i can not remove a system app I can uninstall the SU upgrade i did from mkt...which i did and rebooted, no luck. are you or anyone familiar with the "root checker" app? i can send a log if anyone can make sense out of it.
maruf010 i earlier post i said this is the first time i have tried anything like this with my phone ...i had soneone else root and install infused 2.1.0...i only attempeted the upgrade so...wonder if you can PM me and if you can maybe walk me through your second option?

I'm running out of ideas bro, I consider my self a "Rom flashing junky " flashing from one rom to another since my first captivate! let's do this again step by step, hoping this time it'll work..... make sure to transfer "titanium backup " folder to your computer before doing this. You can use it back later.
1) run gtg's back to stock using Odin
2) root the phone using super one click
3) drop all three the the new rom(2.1.0),
update v2.2.3, and the community kernel
4) download sgs kernel flasher from market
5) flash the community kernel, wait about 10 min let it do its thing till your phone comes back to live
5) power off the phone
6) using 3 button combo go to RED clockworkmod
7) install zip from SD card (flash the actual rom 2.1.0)
8) flash the update ( from 2.1.0 to v2.2.3)
8) finally do a wipe/factory reset
9) install titanium backup from market
10) restore your "missing app with data" only.
I know you did everything what i just said but my suggestion is to you ,do this again.

upgrade 2.1.0-2.2.3 LOST ROOT
Well, lesson to all. make a back up no matter what you do. Shouldn't of had to with an update but....since i did do a back up ..I AM BACK to 2.1.0 where i guess the saying is true...if it aint broke don't fix it. all is well..root back!. If I try going back to 2.2.3 i will do full install.
Thanks to everyone who had an opinion. weirdest thing ever...still bugs me why the ONLY this wrong with the upgrade was i seemingly lost root.

Glad u found a fix bro!

upgrade 2.1.0-2.2.3-LOST ROOT
Thanks!!! I'm all happy again. If anyone else has this issue...i really do beleive it is SU. Look at it on the mkt..since the 3.0 upgrade there have been many issues. I uninstalled the 3.0 SU upgrade and now i'm back to 2.6.3.1 BUT my binary is 3.0. I have yet to trythe infused upgrade again...IF (and when) i do it may not work because of my binary BUT all is well back on unfused 2.1.0!! No way to uninstall binary upgrade to SU i guess.
IF IT AINT BROKE--DON'T FIX IT..YEAH RIGHT ! LIKE WE ALL WON'T KEEP ROMMING!

upgraded infused 2.1.0-2.2.3 lost root
I am still having this issue when trying to upgrade infused from 2.1.0-2.2.3!!! Can someone answer this? The upgrade goes fine but then SU thinks im not rooted and then i can not restore any back ups cause titanium won't work. I haven't tried full zip only because i do not want to have to fetch all my apps again...zzz. I t looks like a lot of people have moved on to MIUI but i want to conquer this first..hahha
NOw, in the CWM instructions it says if you have a voodoo folder on your sd card delete it..well, that is for first time install....if i am trying the upgrade should i still delete the voodoo folder on my sd card? then move on to steop 7?? I reallly doi not want to delete something i may need. Inside that folder it is a log folder but in that log folder there are some CWM-recoveries..???
oh, and not sure if this matters all all but whn flashing upgrades or full ROM does it matter what you have your file system mounted as??
Anyone out there?? I just tried the update again and same thing...SU won't work...tried going into CWM and , download rom, super user, and i d/l SU from ther but then it says press ok to boot into recovery and finish unstalling...i press ok and nothing happens. I manually go into recovery...then what? Where did the download go and how do i finish installing SU??
PLEASE anyone...also, there is an option in recovery to "apply the update" Never used that one before...i just install from SD then pick the update...do i have to "apply update" after install then reboot?

[Q] Why does my new Atrix2 keep crashing and rebooting????

Hey guys, I'm currently on the ICS leak and SCV7 rom, and my phone just keeps crashing and restarting, I've cleared the cache and dalvik cache multiple times, I don't think it was doing this on 2.3.6. What can I try? I just took this thing out of the box

Couple things you can try:
Factory reset.
Try NOT overclocking.
And try removing the supercharger script.

Thanks for the reply, it was doing it on the leak as well because I had a lot of trouble getting it rooted. It seems that every time it crashes it goes through the boot loop, crashes at a certain part, then boots properly to the lockscreen. The phone feels awesome and fast but extremely unstable. Another problem I'm having, root doesn't seem to be working, "Super user has denied Super user request" nothing can get root, so I can't boot into CWM to try and wipe stuff properly. Maybe I got a dodgy version of the leak or something I'm not sure, I guess I'm lucky I didn't install the OTA and I can go back. Any idea on the root situation?
EDIT: Just did a factory reset in stock recovery, can you tell me how I can go about not overclocking removing the supercharger script? And once it boots, if it boots, I'm going to try and root using the ICS .bat root script and hopefully I can get into a custom recovery.

When installing SCv7 is it normal for it to get stuck on the Preparing SCv7 message and then reboot? I'm not sure if it's installing scripts and restarting the phone or what... Because it did this the first time I installed it, and it's doing it again now after a factory reset. If I can get into CWM I'll try and flash the rom again. Can I flash the other ICS rom after a wipe, or do I need to FXZ back to 2.3.5, OTA to 2.3.6, flash the leak, then install the other rom?

I installed the other rom based on the leak, same problem, tried without my sim card, without my sd card, just keeps crashing, boot looping, and being generally unstable. Atm I'm using Jims FXZ script to go back to GB, I'll update to 2.3.6, keep everything stock and see how the phone goes, I'm really hoping I don't have the same problems on GB, because if I do then it seems like a hardware issue, and I really can't be bothered sending it back. I'll keep updating.

Rdavisct has posted in the SCV7 thread about how to remove those, and yes mate, I think you're on the right track with FXZing back to 2.3.5 and the re-updating to ICS.
Let me know how it goes. I'll keep an eye on this thread. :fingers-crossed:

I need to get the battery charged then I can fxz back to 2.3.5. Hopefully it all works out. Any ideas what would have caused the crashing?

I hope it all works out because I literally only got to use the phone for about 5 minutes . Really liked ICS, super smooth super fast, screen is awesome. Crossing my fingers. My old HTC at least lasted a month or so before bricking .

[Q] ICS freezing randomly after rooting?

Hello all, I'm a newbie here. I have just updated to ICS yesterday and decided to root it today. The root process completed successfully without much drama, but I've noticed after the root, my phone is freezing up A LOT. ICS was silky smooth running Nova launcher before i rooted it, so the root must be the cause of the problem. Each time it freezes up, I must fully reboot the phone to have it working again. But since I don't see anyone else experiencing trouble, I assume it's some of the apps that are acting up instead of the actual root?
I never rooted 2.3.6, so I'm completely new to this rooting thing. If this is a common occurrence right after root and will get better over time, pls let me know so I can feel better lol. If not, how can i find out where the problem lies?

Doesn't sounds like root to me. do you have CWM? If not, flash it and then boot into recovery and clear your cache

Are you rooted with superuser or supersu? I am rooted with supersu without issue
Sent from my SGH-T769 using xda app-developers app

i followed this guide
http://forum.xda-developers.com/showthread.php?t=1919228
so i assume superuser? and i guess i have CWM
i think the problem is going away now...although i lost about 10% of battery...
hope this battery loss is part of the freezing and not part of rooting consequences..

Did you happen to restore any apps or anything after root? If not try a factory reset through cwm. Make sure you backup whats on your phone first

I didn't restore anything, and as i'm typing I'm doing a titanium backup. Will certainly try that after its done

[Q] I need help.

I'm not a dev, but it's obvious to me something is wrong.
I re-flashed the eaglesblood ICS rom using clockworkmod recovery v.5.8.1.3 (touch version)
everything seemed okay.
until i started putting apps back on my phone with app backup and restore.
I was getting "process syystem has stopped responding" all over the place.
Then the phone crashed.
it keeps booting, only three apps seem to be running that show themselves in the taskbar, Groove IP, GV SMS integration, and Battery Notifier (Big Text)
It sits there, one one of the home screens, LW animating slowly as it will.. then the phone reboots for no reason.
I installed 4 or 5 different logcat apps but i can't make heads or tails of them
and adb logcat > logcat.txt just spits out this :
/sbin/sh: exec: line 1: logcat: not found
dmesg spits out the log i'm attaching.
Can anyone help me? If i can save the log from one of the logcat apps, will that help?
I'd rather not have to reflash and re-install apps AGAIN.

Where you flashing EB 4.0.4 from gingerbread ?
In any case a full wipe and reflash of the ROMs would work fine. Then reflash the appropriate gapps, But when restoring the apps using TB just restore at apps and not their data. They sometimes don't play well.
I had a similar issue when I tried flashing the 4.2 gapps on 4.1.2 keyboard would crash everytime and any app that uses even one of the google services would crash right away.
I cleared dalvic cache did a dirty flash over my existing 4.1.2 , reflashed the 4.1.2 gapps then I fixed permissions and in was good to go.

so a dirty reflash and fix permissions might help?
Funny enough, after posting that, and hitting reboot on CWM recovery.. the phone came up with the cord plugged in, and seems to be stable for now.
Uhm. i was flashing from.... heck if i know, i've tried a bunch of roms.
the phone INITIALLY was 2.3.4

*grumble* damn sun-downer phone. SO all night it was crashing.. So i finally got irritated when i went to bed, yanked the battery out and plopped it on my night-stand by my fan.
This morning i put the battery in, turn it on, and it seems stable.
What the heck?!

logs.
So... between all the log apps i've played with i have a bunch of logs.. if anyone could look them over and tell me if they see a problem, i'd appreciate it.

Re-download Rom+Gapps
Place on SD card
Re-nvflash cwm recovery 5.0.2.0
Wipe data/cache/davlk/battstats/format system
Install rom+gapps
Wipe cache/davlk/battstats
Fix permissions
Reboot
Using touch is sometimes buggy, 5.0.2.0 is most stable. Restoring apps/data is sometimes a messes things up.
