Hello, i need help on how to fix a bug ive encountered with my root. No matter what i do i cannot mount system as r/w, i cannot update subinary normally or with twrp, i cannot uninstall the subinary or any other root tools like busybox. I think i encountered the problem trying to flash an ota update using flashfire. So far nothing ive tried works, ive tried uninstalling from withing the supersu app, ive tried manually deleting the files but as i said my /system folder is locked in r/o mode. Ive tried factory reset and all that does is soft brick my phone. Please help and ask for any information that may be needed and i will provide it to the best of my ability. Thanks

Would you mind posting a link to the zip i need to flash, i did try flashing one named "UPDATE-SuperSU-v2.78-20160905010000.zip" but it didnt do anything.
Is it because i need to rename it? Also where should i place the zip before installation? I tried flashing from my download folder and the root of my external sd card and neither worked.

yes v2.78 is the correct one , it doesn't matter where you put the file but it's better to place it on your sdcard not ur internal memory

So what am i doing wrong for it to not work? While in twrp when i flash it it says that is succeeded but when i boot back into system nothing changes except the supersu app is gone and i have to reinstall it, but when i open it it still says i need to update the su binary.
Edit: thank you so much! for trying to help me but nothing is working. I posted my problems with a lil bit more insight in hopes that there are (no offense) more advanced users there that may know exactly whats wrong and how to fix it if its even fixable
Update - thread can be closed
Problem fixed, to fix the problems i was having i had to download the stock system files for my device and flash them, after that just installed the latest supersu 2.78 zip and remount problem is fixed.

Might be a silly thought, but have you enabled the unknown sources option...?
Lee
yep thats been done,
under Security > Unknown Sources is ticked
doesnt seem to be anyother settings that i could've missed either.
Hmm. Odd bug then. I can't help (or confirm) yet as I'm doing a system dump before flashing (LPH to LPQ, full wipe + internal sd format). Copying everything from my internal sd to the pc takes a little while, it was nearly full...
You've tried the nasty shotgun approach of clearing caches and fixing permissions...?

wrong thread
Working fine here. I did a wipe before install as it wouldn't work the first time I flashed.
Working fine here. I didn't wipe.
The only thing I noticed is that some apps, previously installed, didn't work. I uninstalled them and reinstalled them from the internal SD Card.
Do you have Root? Depending on how you flashed your phone, you may have lost root access and thus some apps that require root may not install.
i agree it is an odd "bug" not sure why it would do this.
when the install application screen comes up, only the cancel button is responsive.
also i can confirm i have root - i flashed CF_root strait after.

Flashing back the stock kernel will actually solve the problem. For the case of rooting your phone, you can use:

READ AT THE END OF THIS POST FOR THE SOLUTION
I accidentally used Titanium Backup's widget to frost all system and user apps, leaving mi phone in a infinite boot animation loop. I dont have aNandroid Backup and I would really love to solve this issue without flashing.
I found at Titanium Backup's troubleshooting webpage that I could use this command with adb to solve my issue:
Code:
Type the following command (replace with /dbdata/system/packages.xml if you have a Samsung phone):
busybox sed -n 's/<package name="\([^"]\+\)".*enabled="false".*/\1/p' /data/system/packages.xml | while read PKG; do pm enable "$PKG"; done
but it just says: No such file or directory (yes, I changed /data to /dbdata as stated in the webpage)
Any idea on how to solve this issue?
Thank you!
**EDIT:
This is the way I managed to get my phone working again without having to flash or wipe:
1. Boot in recovery mode and used adb pull command to extract "packages.xml" and "packages-more-backup.xml" from /data/system/
2. Open both files with Wordpad and replaced all protection="2" or "3" lines to protection="1".
3. Also, and very important, replaced all enabled="false" lines to enabled="true"
4. Boot in recovery again and used adb to delete old "packages.xml" and "packages-more-backup.xml" files and push the new ones.
5. Reboot and Voila!
6. Boot once again in recovery mode and fix permissions to avoid any problem.
Hope that this could be usefull to someone else having this horrible problem.
Thank you all!
Checked for that file on my phone, it doesn't exist in /dbdata/system/, but it does in /data/system/
It's probably fixable from the command line with Linux but that is over my head, one option would be to Odin or heimdel back to stock, and start from scratch. You might need a jig to get into dlmode.

I wonder what would happen if you removed the app (its apk) via adb from /data/app. Would it retain the freeze settings? Something to consider trying.
This happened to me. I reflashed the ROM without wiping and all was back to normal

I tried doing that right now but it didn't worked
I got a little too punchy with titanium on my 3 year old original Galaxy tab 7 and froze a samsung system app. Got irreversibly stuck is soft brickland - Tried various methods before giving up and hitting the wipe and reset to factory restore in the system recovery mode. Everything was backed up except recent photos, so it was more annoying than the end of the world.
Odd thing was when it reset to factory, it appeared to do just that, yet when I plugged it into PC and mounted it - the memory was full and all my files and app data files were there - untouched. The apps themselves have gone except one - Superuser is still there, Does Superuser somehow override being reset? and act as a guardian of your data in the event of reset?
Odd. I was expecting to run some file recovery software to a salvage what i could, but viola - it was all there.

ZIP for unfreezing apps
For those, who accidentally frozen important system app: here quick solution without factory reset, reflashing and ADB
It automatically edits files as described in first post.
You should have unlocked bootloader. If no, ZIP useless because unlocking wipes all data.
Download both ZIP's and just flash them via custom recovery (TWRP / CWM)
If first throws error try second and vice versa. 2nd with mark "New" contains newer updater-binary that must be compatible with recent TWRP.
Then all apps will be unfrozen, so phone will boot.
Fix compatible with all Android versions.
Note: also you can somehow (ADB or filemanager in TWRP) delete file /data/system/0/package-restrictions.xml
More correct to edit that file which ZIP actually do, but deleting not harmful too.

Thanks very much for the zip. It worked great
Same Problem
Does anyone have an updated version of that zip? I also froze an app linked to the device and it won't boot, even after factory resetting it. Tried running the zip on my t-mobile GS4 (probably newer than that zip) from the SD card in recovery mode, however it didn't unfreeze it.
Any help greatly appreciated!

1. To flash that ZIP you need have custom recovery (CWM or TWRP), not stock.
No update needed, it still works in this case.
2. That strange. Maybe you not really performed reset?
Double check all and try again.

Yup, unfortunately I did select wipe data on the recovery screen. I am also stuck in an infinite boot up loop and cannot access the phone to install any apps. How can I use a custom recovery to run the zip file if i cannot access the phone? Instructions much appreciated. Thanks again.

ZIP – it's not app.
Again, you need to install custom recovery.
Here link to TWRP and how install it via Odin on PC.
You need place that ZIP on sdcard.
Enter in recovery (don't know how on your model), select Install > find ZIP > confirm > reboot,

Downloaded TWRP with Odin and ran custom recovery without a change after the zip (this must have been a deeper-rooted problem in the OS itself), however in the meantime I formatted the system partition, removing the operating system. Installed Kies and ran the update. It reinstalled the OS and I'm good now. Most stuff was backed up anyways. Thanks guys for your time :good::good:
Which apk is the culprit?
Man, I wish I'd found this thread before restoring my phones internal ROM. Had it rooted and set up in every way I like except removing bloatware.
Using TB, I froze a system apk that shut down my System UI and sent the phone bootlooping. What I'm trying to determine is WHICH apk(s) I froze that caused this. I thought I had researched each one that didn't seem obvious, but I musta missed one or one of the 'obvious' ones wasn't so obvious.
Hello!
My GT-i9100T is my first android phone, I've been using for two months and I love it. This afternoon I decided to root my phone (I have never rooted or installed a custom ROM on this phone before) using this method, and I downloaded all the files and followed all instructions. When I selected 'apply update from external storage' it took a little while and gave me this error: 'E:unable to mount /sdcard (No such file or Directory)'.
I searched online but I couldn't find anything helpful but I did factory reset my phone and yet it still didn't work. Can anyone help me?

i think u should have put the files in ur internal sdcard not external, please check by doing so and see
ps - alternatively u can put the file's in ur cache folder and select 2 install the same from cache in recovery and see
Thanks for the swift reply!
I don't have an external SD card and I've never used one.
EDIT: I can't do that because the cache folder is inaccessible.

then try the alternative ie cache folder option and see, since the cwm .zip does require an extsd since thats the one giving u the error while updating if i am correct

You need a physical external sdcard in order for this to work.
If you're in need of root just flash a CF-Root kernel..

Why? And you didn't exactly help by giving him the wrong information. Quite the opposite in fact. On the plus side, you've been thanked not once, but twice for giving that wrong information. Excellent.
Okay, first, I have tried googling and came up with no answers. Second, I tried looking through xda and came up with no answers. The closest thread I found anywhere was here. Here is my situation.
I have the EVO 4G LTE and I am running stock and rooted. Over last weekend I became s-off. So, now I am s-off with a stock recovery and would like to install the OTA update that is out. Please don't tell me not to in this thread and just wait for a rooted ROM and the like. I know the risks involved and what potentially could happen.
Ultimately, when I try to apply it I get the red triangle. When I hold the volume up and power on it goes into the stock recovery and here is what it says.
Finding update package...
Opening update package...
Verifying update package...
Installing update...
Copying to fotaBoot to /data/system for customize reload...

(Status 7)
Installation aborted.
So, what this tells me is that soundhound is preventing me from installing the update. I didn't even have soundhound installed when I tried the update. Also, I looked with root explorer under /system/app and there was nothing listed for soundhound or the like. I thought just deleting the file would maybe solve my problem. I also tried installing it from the market. I think I must have accidentally restored this file from a different backup on accident and don't have that backup anymore.
So, this leaves me to my quandary. What can I do to install the OTA? Does anyone have any thoughts or insight? Thanks in advance.
Okay, I have tried this as well. I flashed the most current TWRP recovery and wiped cache and dalvik cache. Then I flashed a stock recovery and tried the update again. I received the same error as last time with the stupid soundhound.odex file. Does anyone have a soundhound free file with the apk and odex file? I figure if I had that I could place it in the proper location with root explorer or adb install it to get the update to apply. Still, any thoughts could be helpful.
It might be a way for HTC to prevent rooted phones to update as how u explained it soundhound isn't installed but when u purchase this phone it comes with sound hound preinstalled into system directory which u cannot uninstall without root privlages
Sent from my EVO using xda premium
I appreciate the input. I guess I forgot that soundhound comes preinstalled on the phone. I just checked the RUU and looked at the rom and you are right. It is there. So, now I have the .apk and .odex files from the stock rom. My question is now how do I install it so that it looks like it was there from the beginning as a system file?
Thanks again for reminding me it came with the phone. I feel I am closer to being able to install the update.
DONE AND DONE!!!!
First thing is that I changed the title because it was not SoundHound's fault at all. It was my idiot self that uninstalled a system app. I don't remember doing that but I won't deny that somehow I did.
Now to the meat of how I solved this.
I got the correct system files (both .apk and .odex) and placed them on my sd card
I mounted /system/media as r/w with root explorer and copied both files into the /system/media directory (must do this first before putting them into /system/app)
I changed the permissions to rw-r--r-- as were all the other apps in the /system/app directory
I copied both files over to /system/app
I rebooted the phone
Once the phone rebooted I updated the app in question and opened it
I rebooted again just to be safe
Then I downloaded and installed the update
SUCCESS!!!!!
Anyway, just wanted to share for everyone in case you run into a similar problem when trying to update. Reach out to me if you need any help with any of the steps. Thanks to such great people and developers on xda.
Some threads are saying that even if you're S-Off, the new HBOOT won't let you flash Superuser and TWRP. Were you able to reroot?
For various reasons, I'd like to just take the OTA and reflash SU and TWRP (I'm S-Off, rooted, stock recovery right now).

I was able to reroot. However, first I had to install the lazy panda hboot and flash TWRP through fastboot usb. I then flashed a su zip once I booted into TWRP. Hope this helps. I am trying to make a new thread for this right now.
I had the same issue but with a different problem. I had rewritten my build.prop to incorporate the application associations as they should be (thanks Crapple!). As a result, the OTA was failing to install. Volume UP + Power showed me the error. Restored the original build.prop I had backed up and OTA fired off. A few more steps and I'll have your S-OFF OTA rebuild complete. Thanks!

But my phone is rooted and i can use all applications that i have installed.
Also when i connect phone with pc, and if i want to delete any folder, i get a warning 'the storage is write protected' (sdcard0). But phone is rooted.
I already did factory reset, and i try to format usb storage but files always come back. I also rooted again I've put all my knowledge, but i can't find a solution.

OP have you find it?
You both need to flash stock firmware in download mode with Odin as many times as you need to until your phone works normally again. If you have problems with Odin or flashes appear successful but the phone still won't boot normally, search for Hopper8's 'Odin troubleshooting' thread & try the stuff in that thread. Specifically, If you're in a situation where flashes appear to be successful but the phone still bootloops, flash the 3 part firmware linked to in his thread (only if you defnitely have an I9100 though; if you have another variant, don't).
