Modified platform.xml--Now no wifi or any sd access - Fire Q&A, Help & Troubleshooting

I have the Fire 2015 on FireOS 5.1.1
Rooted and has google play services.
In order to gain write access to the external SD with TitaniumBackup I modified the platform.xml as follows:
Original:
<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
</permission>
New:
<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
<group gid="media_rw" />
</permission>
Upon reboot, I have no access to the microSD card using ES File Explorer. The internal partition sdcard is also not accessible and shows no files or folders. I can only view the system partition.
Additionally, I cannot access the internet, although I can connect to my wifi network.
When I try to write to the internal sd "0" partition, I see "open failed: EACCES (Permission denied)"
I tried removing the changes in the platform.xml file but I could not save them, even with root explorer turned on in ES File Explorer.
I installed fx explorer and its root module using adb. I was then able to edit the xml file, taking out my change, making it original. I rebooted the device and the issues still persist. I figured this would happen because I have read other users' report issues even when replacing the modified platform.xml with the original.
(I cannot access root with it using "adb root" as it returns "adbd cannot run as root in production builds")
I tried a factory reset. The issues still persist.
At this point I might have to wait until there is a method for custom recoveries on 5.1.1 in order format /system and flash a custom rom. I was fine with being on fireOS with root...I just wanted to use TitaniumBackup with the extSDcard. I should have picked a different method!
Any ideas?

Start over. Reinstall FireOS 5.1.1 > root > block OTA > add google play.
See the thread on restoring stock FireOS.

No luck

Thanks for the reply, bluberry.sky
So I successfully sideloaded my firmware version. It didn't work.
It restored all the stock fireos apps and everything, keeping a couple non amazon apps I had pushed to it earlier. Wifi settings were saved too. Issues with wifi and extSDcard remain.
I thought for sure your suggestion would work...

You can wipe with FlashFire

FlashFire worked for me. Since I saw it was possible to flash SlimLP with 5.1.1 I went ahead with that, rather than just wiping and restoring with a manual sideload.
1. I adb installed FlashFire
2. Used OTG-USB to copy the rom and gapps to root directory of device
3. Used FlashFire to wipe and install SlimLP
Man, it is so much snappier than FireOS.
Thanks for the replies.

How do I create a back of system, recovery and boot without root

I want to back up system, recovery and boot so I can root and be able to go back to stock to take otas without having to go back to kitkat and factory reset and all. Otas won' t apply to previously rooted systems, so how to create one without rooting first? I tried twrp, it seems to create a backup but when looking in the folder nothing is there.
You can't
You can't. Because even with ADB commands the phone request for root privileges
It could be that TWRP is using the "legacy" path instead of the default "0" path for the SD card. I use FX file explorer to browse to it. It can be found at /storage/emulated/legacy/. The TWRP folder may be found there, and if so, it can either be copied to /storage/emulated/0/ or you can simply upload the entire folder to a cloud storage of some sort.
Additionally, you would have to restore stock recovery following a TWRP recovery for obvious reasons, so you have to make sure that the stock recovery image is available somewhere to fastboot flash it.
That said, with the new SuperSU, I don't think it modifies the kernel any longer, so a simple unroot from the app would restore /system back to default. The root method simply boots a permissive kernel instead of replacing your phone's kernel. And you wouldn't need to have a TWRP backup of your system partition. Also keep in mind that you would have to restore any other mod to /system such as ad removers which replace the hosts file or wakelock detector app helpers that need to write to /system.

On LG G4 - How to replace SuperSU.apk in /system/app from /data/app so it works?

Here is the scenario. I updated SuperSU v2.46 that came with the LG G4 root injection method with SuperSU v2.52 by running the Superuser.apk which basically installed /data/apps/<appname>/base.apk which worked as v2.52 except SuperSU will not install itself to /system even though I selected that option in SuperSU in which it said it will need to do a cleanup and reboot. So I manually renamed the base.apk to SuperSU.apk, changed the owner/group to root/root and kept the permissions as rw-r--r--, moved the file to /system/apps/SuperSU/SuperSU.apk, deleted the /data/apps/<appname> folder for SuperSU and restarted the phone. The only thing is SuperSU does not show up in the app launcher and the SuperSU.apk has the Android icon instead of the SuperSU app icon so I flashed the SuperSU v2.52 zip file with flashfire and it did restore /system/apps/SuperSU/SuperSU.apk with the correct icon except the problem is I noticed with Android 5.1 lollipop, you just can't replace a .apk in /system/app by moving it from /data/app as it will not even show up in the launcher. Not sure if this is a Lollipop thing or a LG thing as on previous Motorola phones running 4.4 Kitkat and below, replacing the .apk will usually work. I've cleared the app cache, deleted the files in /data/dalvik-cache/arm, /data/dalvik-cache/arm64 and /data/dalvik-cache/profiles without deleting the folders as I don't know if it's safe deleting the folders and also clearing the system /cache to see if it makes a difference. Didn't work. Does anyone know how I can fix this because it seems like once you updated to a newer version that installs in /data/apps, even if you delete the /data/apps version, it will not use the /system/apps version and simply ignore it. The only reason I still have root is probably because of the su binary still on the system.
Try:
- Make sure you've manually removed all SuperSU's APK files (/system, /data, etc)
- Reboot device
- From PC: adb uninstall eu.chainfire.supersu
- Or from root shell: pm uninstall eu.chainfire.supersu
- Reboot device
- Install SuperSU.apk (via adb, file explorer, Play Store, etc)

My only concern is that on the LG G4, the original SuperSU was injected into the system image and as I have a locked bootloader still, it seems like if I did that, the only way I'll get root is if I reflash the system image again. It doesn't happen with just SuperSU but pretty much any apk in system that gets a newer version installed in data as it seems even if the data one was deleted, it will never use the one in system again.. Is there a way to use either adb or pm and install to system instead of data?

How to edit hosts file?

How are you able to edit the hosts file in systemless route? I used SuperSU 2.66 flashed on MMB29S build. All I want to do is set up some redirects and possibly adaway.

You have to make some space. Is not systemless root that is the problem. Changes in marshmallow made the system partition full. Reboot into twrp, mount system in rw and delete some unneeded apps in system/apps
Korean and Hindu keyboards for example. But dont delete the latin one. Or some google apps that can be added back in from the store.

I deleted sheets using Titanium, so it must be the mounting. Time to go search on how to do that. Thanks!
Trying `adb shell mount -o rw,remount /system` and get `mount: can't find /system in /proc/mounts`.

They look like they are deleting in TI, but they don't delete. I just flashed the January update today and that is what happened to me. I have seen that twice now. Cant help you with the adb command, I just used twrp to mount and delete.

Totally didn't even see that option. You just reboot after checking it? Every time I go back to it, it's unchecked.

Since checking mount system does nothing, I went into Advanced > Terminal and did an `rm -rf GoogleHindiIME` and still can't edit the hosts file.

I mount in twrp. Delete hindu and korean with the file manager in twrp. Reboot, install adaway and it works. I have never manually edited it.
No, the system mount in twrp does not stick on reboot. Mounting system with systemless root is tricky as I understand it. So I just avoid it.
You can't mount system as rw in a booted Android system unless you have a permissive kernel, and you should not have a permissive kernel.
Had the same problem and didn't want to remove things from /system. You can follow the steps here: http://forum.xda-developers.com/showthread.php?t=3266107
Systemless root on 6.0.1 - How to edit build.prop
Sent from my Nexus 6 using Tapatalk

HTC One mini 2 shut down while editing .system

I have rooted my phone, root checker said it was fine and supersu works fine.
But I can't edit system files through esFileExplorer (in root mode) and other way (by entering in twrp recovery).
I think it's not done the root, but idk what can I do. Should I root it again?
I wanted for disabling LPA in build.prop.

Agh, wrong-
Apps & ADB option is not in my Developer Options,

These options only exists in CM & LOS.
As I recall correctly, it's not possible to edit every file despite gaining root access in stock ROM, the work around to this is to copy the file to another location in your phone or into your PC, edit it, then copy the edited file into the phone to a different location, then rename the original file (as backup incase of failure) to anything else, then use TWRP to overwrite or copy the file into system directory using advanced feature, then restart device for changes to take place, if even after restart the changes did not take effect then you will have to use CMD to overwrite the file, the latter should work as I have tested it before.

In that case the only option remains is to flash the file through CMD.

Marshmallow
---Working on a method---
(Won't stop until I have every update rooted.)
Marshmallow is currently unrootable on the G900A and G900V (CID 11). A method will likely appear in the future.
It is safe for you to flash to the latest Marshmallow, you will be able to restore the experimental combination to root again.
Notes: This guide is an updated version of AptLogic's Guide. ( Can a mod please sticky that thread )
I have created this thread as an "elimination of confusion"/"Catch All" and I will update the thread once I get root on Marshmallow , https://forum.xda-developers.com/att-galaxy-s5/general/guide-merry-christmas-heres-t3516196.

Since I can downgrade my S5 to kitkat does that mean that I can use the CyanogenMod build for kitkat on the s5 or will it brick my phone ?
First off, thank you so much for this guide! I recently got an old Galaxy S5 from my Dad, and rolled it back to KitKat using these instructions.
I'm experiencing two rather strange issues, though.
1) KitKat doesn't seem to be remembering my Wi-Fi password. I'm having to re-enter it every time I reboot the phone.
2) I'm getting a message on booting that "Safestrap is disabled. System will start in 10 seconds." The system starts like it should, but this message pops up every time. Is this normal, or will something correct it?
Any assistance would be appreciated. Thanks!
The Google Drive links are dead. Could we get new ones please @Justin1198?
Thanks in advance!
