[Q] Lost root permissions after flashing kernel! - Nexus 7 Q&A, Help & Troubleshooting

Hello guys,
I was running Smooth ROM 4.3 + Bricked Kernel 0.58, everything was just fine, but I reflashed the kernel to change the GPU's OC (in case you aren't familiar with that kernel, the only way to change the oc of the gpu is by reflashing the kernel, but moving on..)
After said reflash, everything booted back to normal and only a couple of hours later, after trying to enter Trickster Mod, I noticed that I had lost my root permissions on every app. This is not the second time I am facing this problem (I don't recall the circumstances under which this happened the first time), and to fix this problem last time I had to factory reset and reflash the rom, and it's a bit boring having to reconfigure all the system settings again and whatnot.
So the question is, do you know of any way to fix this without wiping+reflashing?
Best regards,
Bernardo Pinho

Thank you for your reply, but it didn't work. I flashed said SU zip and I still don't have root permissions...
(On a side note, I just noticed my chrome browser started speaking out what I click on, this never happened before and I never messed with any accessibility options, do you have any idea on how to fix this? 0.0)

Bump!

Need help - freezes and restarts

I updated my phone to latest liquidsmooth rom two days ago and the phone freezes and restarts/reboots randomly like sometimes when im on phone/ playing a game/ using browser/ connected to charger. Yesterday I changed rom to latest carbon rom. Did install (3 wipes) as told in the thread but im still having the reboots.
Im using TWRP recovery and had used Utility 1.10 to go back to stock from Energy rom with safestrap recovery.
Can tell me whats the prob? Is it the kernel problem?
Have you tried upgrading or reflashing TWRP and then doing a clean install of Carbon? Its probably worth doing a fresh download of each first just to make sure you cover all your bases. These reboots were happening to me a few months ago and it drove me mad. following these steps fixed it for me.

Honestly, if you're using SafeStrap, that might be your problem. Remove SS and flash the ROM in TWRP. If your bootloader is unlocked, you don't really want to use SS. Also, make a stock backup in TWRP, prior to flashing. This way, it will be easier for you to recover in the future, and you won't need to go through the painful process of fastboot.

Thanks man. I will upgrade TWRP or reinstall it first. Thanks for that tip. Will post again if it doesnt work.
Still having those restarts. Really irritating. Froze and rebooted 4 5 times today morning while I was on call and trying to message. I reflashed reinstalled everything. I used both Utility 1.10 and 1.20. Im getting reboots even the stock ROM after using the Utility. I am confused which Utility I should be using. I had no issue of rebooting before flashing using Utility. Can someone give me exact procedure to reflash so that i know i am not missing out anything.

you might need to do a clean install.
- what version of TWRP are you using (anything other than 2.4 should be fine)?
- to perform the clean install, mount system, then try wiping everything (system, factory reset, & internal storage) - DO NOT WIPE external SD (I presume this is where you store the ROM files
- after wiping, reboot recovery, then install whichever 4.2.2 ROM you want follow by the GApps (use the 3/2013 version)

Since TWRP wasnt working for me, I tried flashing with CWM recovery by hashcode. Still had reboots. I was using TWRP 2.3.2.3
When you say wipe everything, does it include 'modem' and 'pds'? Saw these two options also inside Mount/Format menu of CWM recovery.
Also there was an option 'Mount sdcard' (internal I suppose) but when i click it nothing happens it remains as Mount sdcard. Rest of it changes from Mount to Unmount. Is there some problem with that?
Do I have to just Mount system only? Also after rebooting recovery do I have to mount system again?
I try again as you said meanwhile.

nope, just system/factory reset/internal storage.
yes, make sure everything is mounted (checked) so that they read "unmount"

Did exactly like said. Got into CWM recovery. Mounted system. Formatted system, data, cache, sdcard. Did factory reset and wiped the caches. Then rebooted recovery. Then installed the ROM, 3/13 gapps, gsm fix. Reboot system. Still no use. I got 2 reboots in 5 mins in the ROM. I checked the md5 of the files and its ok. Dont know what else to try?

are you flashing a kernel at the same time?
I would recommend trying a basic 4.2.2 ROM right now - like unoffical AOKP.
another problem could be the GApps or GSM fix. try installing just the ROM without the GApps perhaps?
carbon was very solid too. unfortunately, I can't help you with the GSM fix, as I am CDMA.

Can't get passed boot logo..

This isn't my very first time with flashing/rooting/etc. but I'm not that adept with it.
Got my S4 2 days ago but managed to get time today to work on it. I rooted successfully and everything was running perfect. I flashed over the newest Beanstalk ROM w/ gapps and it ran fine the first time it ran.
I can't get passed the Samsung Galaxy S4 boot logo every time I try to reboot the phone though...
If I wipe the cache/dalvik and reflash it still doesn't boot passed logo.
If I wipe the cache/dalvik and then wipe data (including the internal SD card, completely wiping it clean), flashing the ROM will work the first time it runs; once I reboot or just power it off then power it back on, stuck at Galaxy S4 logo... I let the ROM run first time through, input only what is needed to get to the home screen (google account/wifi setup/phone name/etc.), then I've tried rebooting it, shutting it down and powering it back up, letting everything update and waiting half an hour and restarting it... all have the same result, stuck at boot logo
I'm using TWRP, I have a recovery for stock but I don't want to use stock.
If anyone can help me out I'd appreciate it.

This is EXACTLY what I was about to try... I'm literally reflashing the ROM fresh right now, going to put the kernel on the SD card, then reboot into recovery and wiping cache then flashing the kernel.
Will using a recovery that was made on a different kernel have any effect if I decide to use the recovery? I've heard bad things about flashing the wrong kernel (even though I know the one I'm about to use is the correct one) and really screwing stuff up if not done properly. I just want to make sure I don't screw anything up permanently.
Thanks.

Use twrp 2.5.0.2 because if your using 2.6 its bringing problems. Also report this to their thread for better help

Since there are no recovery categories according to this page,

I don't see where it would matter. No guarantees though.
I do know it is ESSENTIAL to match the type (TW or AOSP) ROM and kernel to avoid major problems.
I also recommend TWRP 2.5.0.2

By the way can you provide the steps and which files you flashing. Also redownload everything could be a bad download. Make sure to download them in computer and transfer them to your sd card

I did a fresh install of the LiquidSmooth ROM and it's not hanging at boot logo whenever I reboot, and everything is working well. I suppose I'll stick with this for a while.
For my steps trying Beanstalk:
Boot into recovery (TWRP 2.6.0.0)
Factory reset;wipe cache/dalvik
Format Data
Factory reset;wipe cache/dalvik
Install ROM + Gapps
Wipe cache/dalvik
Reboot
I then tried doing that exact process, after letting it boot once I rebooted into recovery and flashed KT Kernel and wiped then rebooted and it hung at boot logo.
I did it again but I installed ROM + Gapps + Kernel then wiped then rebooted and it still hung at boot logo.
I'll download and prepare a new install of Beanstalk and give it another try tomorrow. I'll make sure to backup Liquid in case I want to switch back.
Thanks again for the help!
Glad it's working out for you.
If I may ask here; how do I know if a certain kernel is compatible with a ROM? I know to match the version (4.2, 4.3. etc,) and base (AOSP/ TW) but is there anything else specific that I need to watch out for that could cause problems with flashing a kernel on a ROM?

Not really unless the rom dev for some reason doesn't recommend using a certain one. Kernels will act differently for everyone even on the same device with the same rom. Just need to flash them and find out which one works the best for you (battery life, overheating, smoothness, etc).
Always have a backup handy just in case something doesn't work right.

Stuck on download (odin) mode

Ok, so I decided to root and install zRam swap 4x on my SGS 4, first thing I did was flashing cf auto root by Odin then installing s4 flasher app and giving it root acces and flashed CWM recovery, After that I´ve flashed
[KERNEL][ATT][AOSP/TW/GE - 4.2/4.3][9/17/2013] KT-SGS4 - MFD - LOKI'd - KTweaker
and zip for zRam swap
inside CWM recovery .. not sure when but it asked me to repair su binaries (root access) as it might be lost so I did what it suggested and then the problem starts.
When I try to boot my S4 it ends up in Download mode . what I need(I think) is TAR file of the mentioned kernel (what should have been provided in the kernels OP but it is not! )
My device: GT I9505 version
TW ROM Official 4.2.2
Just flash a recovery true Odin, then boot the recovery, full wipe and flash the rom you want.
Don't touch repair su binaries again. You shouldnt be needing that.

I was hoping I could repair the damage without reflashing the whole ROM with just flashing kernel?? (there is the problem?)
So far, I´ve done some reading and managed to flash Philz recovery via Odin, I have custom recovery now..
Then flash a rom you want and hope it boots. Maybe you have some luck. If that fails full wipe and flash a rom.
I would still recommend a full wipe though. Make sure you have nandroid backups next time you start messing with your phone.
What am I doing wrong here???
I´ve flashed my Rom and it was ok, rooted with odin, flashed philz recovery with odin and then flashed kernel mentioned in above posts, cleared cache, dalvik ..and it still wont boot but goes to Download mode (odin)..
Since I´m still new to this forum and doesn´t have access to post in the right thread I´m using this ..
I really want that feature of zRam and swap on my phone but don´t know what is wrong here!

"Detection information-

When I click on it, it pops up saying that in order to protect my device, it recommends reboot with option reboot now and later...when I click later it disappears and few minutes later comes back again.
I think I´ve read somewhere about it but can´t remember. Any help in solving this problem is welcome! :cyclops:

[Q] What should i do to flash stock kernel?

HI all, I have a Rooted N10 (Android 4.3) with KTmanta Kernel and stock ROM. Before installing KTmanta kernel i made a Nandroid Backup. Now if i want to go back to the Stock Kernel what should i do? Is it SAFE to flash the "Boot.img" in the original nandroid backup? I believe it contains the kernel. Thanks in advance.

It's fine to restore the boot.img from your backup as boot.img does contain the kernel. What I usually like do in this situation is I download the stock 4.3 boot.img (Which can be extracted from the latest Nexus 10 factory image from here https://developers.google.com/android/nexus/images#mantarayjwr66y) and then flash it in fastboot with the command:
Code:
fastboot flash boot boot.img
This will restore your stock kernel. Let me know if you still have questions.

I am much thankful for your help Infact, I do have a question related to flashing kernel. I have read in related articles that after flashing any kernel you must perform the following in the CWM recovery: 1. Delete cache 2. Wipe dalvik cache 3. Fix permissions.
I am using CWM Recovery 6.0.4.3 (the latest for N10 downloaded from CWM website) and it doesn't offer the option of FIX PERMISSIONS. So the last time i flashed KTmanta kernel i couldn't possibly use option no. 3 above. My N10 is running smoothing without any issues. But the thing is, I am asking because I do want to follow the steps as directed by the author of the kernel or the ROM. Thanks in advance

When your flashing a kernel in recovery it's important to follow the directions provided by the kernel developer. Deleting chache, and wiping dalvik cache are essential to ensuring the kernel runs properly and doesn't bootloop your phone are you flash the kernel. As far as fix permissions this utility was removed for recovery because the way it was implemented was outdated and broken, fix permissions is more of a helpful option rather then a necessity in this situation. If you really want to run fix permissions you can download and run Stericson's Fix Permissions App. If you need me to clarify any of my points or anything else let me know I'll be happy to do so.

Thanks again for your prompt reply I don't think i really need to run "fix permissions", as long as my ROM is running good. I am happy that I at least know how to do that in case i am in real need of running fix permissions. God bless you

Flashed ROM in TWRP - custom recovery + root gone?

I just flashed a 802d stock ROM through TWRP 2.7 (AutoRec). I started out by wiping dalvik cache, cache and data. I then pressed Install and found the zip and installed that. After it was done, I did a dalvik + cache wipe again just to be safe (It asked if I wanted and I complied). Rebooted into system. It was quite buggy to begin with, so I wanted to try re-flashing, but it looks like my custom recovery has disappeared. I assume my root access went with it.
Everytime I try to get into recovery. It doesn't show the TWRP recovery, but merely ask if I want to factory reset my phone.
Currently, I'm downloading a clean kdz of the 802d ROM (it's taking a while) and aim to start all over with rooting and installing custom recovery and re-installing apps, but if anyone has a different solution, it would be most welcome. I'm quite the noob here. I thought TWRP would be fool-proof and would therefore allow me to restore a backup at any time. But currently, that does not appear to be the case.
Please do prove me wrong
Depends on what custom rom you were installing.

Ok first if you really do have custom recovery in the factory reset screen clicking the power button three times will boot you into recovery, if you can boot into the Rom then download a root checker app to check if you still have root

I just checked for root access - it's not there anymore. I will try to boot into recovery now through the method you suggested. I'll edit my post with the results.
Edit: Your method worked My recovery is there. Great! I thought it would boot straight into recovery, so the factory reset option mislead me. Now, I have to ask: did I do anything wrong in my flashing? For example. In the Mount section, only Data and Cache is mounted. Should system be mounted or is it irrelavant? Is there anything in particular I need to do in Wipe? I merely pressed Advanced Wipe and seleceted Dalvik Cache, Data and Cache and swiped to wipe. That's it.

Yeah, I did read that. This might sound stupid, but I figured that the listed SuperSU update was meant for people with an older version of SuperSU as in making sure to have the latest version of SuperSU, since I already had the latest version, I neglected to do that step. My bad. I will copy the zip in question to my phone and try re-flash both zips and see what happens. At least I have my backups to fall back on.
Another dumb question if you will. Since I didn't wipe any of my data. My apps are still present in the file system, but they are not installed nor do they have market links. Is there a way to install them or should I try to recover them through Titanium Backup? Or is it easier to simply wipe the data as well and use Titanium Backup to restore my apps?

I think you should wipe and restore from tibu since there isn't a guarantee that redownloading your apps from the playstore will keep there old data
Thank you so much for taking your time to answer my questions. The second flash seemed succesful, but it didn't fix my biggest reason for flashing the ROM in the first place: the hissing audio bug. So I'll just try to do a restore of my latest backup and I'll make do with my temporary fix that actually works.
While it may seem to that I have wasted everyone's time, I think I've learned some valuable lessons, so I don't think it was entirely a bad thing
Hopefully, my restore will be succesful

just in case since you don't mention the fix, I know the kk audio bug has a fix with g2tweaksbox over in the faq of first post it explains what needs to be done

I did try that fix. It didn't remove the hiss entirely for me. Maybe removed 50% of the hiss, but I've heard of it working 100% for a lot of people. I've been using the ELT > Audio Loopback test from the hidden menu. It removes the hiss by about 99%. Only annoying thing is that I need to do it on every reboot which is why I wanted a more permanent fix.
Seems like my restore has caused a bootloop. Everything went accordingly, except the installation of SuperSU afterwards. Kept saying it failed to copy to the system folder despite system being mounted. The bootloop started when trying to boot into system after restore + failed SuperSU installation.
Edit: Fixed the SuperSU failure to install by wiping dalvik etc. but bootloop persists. I somewhat assume this is because the restore function doesn't work when the current ROM is different from the ROM the backup was made with? The backup was made with D802 20b firmware and the current ROM which is the one I flashed was the D802 20d firmware. Am I on to something?

A backup restore should always work whether different versions or not, are you able to get into download mode?have you tried kdz to stock?
Sent from my LG-D800 running stock kk, rooted with philz using XDA app

I just fixed it by going into recovery and flashing the D802 20d firmware again. It'll do for now. Honestly don't know why the restore from backup didn't work. Either the backup was corrupt or I've done something wrong.
I did restore my apps (so far) flawlessly and the rom does appear to perform similarly to my older firmware. Plus there's added features such as knock code so it's not all bad.
I do have a D802 20d kdz firmware available on my computer in case I want to go completely stock and/or start over. But I'll give this one a try over the next few days and see whether I'll keep this.
