Can't mount system as r/w on rooted device - Xperia Z1 Q&A, Help & Troubleshooting

Hi. I will try to give as much info as possible so bare with me.
I have a Sony Z1 C6903 on build 14.3.A.0.757 Android 4.4.2
I rooted it using a prerooted firmware method with duel recovery (I think by doomlord not 100%) which involved downgrading my firmware back to Jellybean then rooting it and then flashing the prerooted firmware ect..
The root method worked perfectly and my device is fully working, but just recently I tried installing the features for the camera from the Z2 which involves moving the apk to the system/app folder but none of the apps can mount my system as r/w, I have tried ES File Explorer, Root Explorer, Total Commander and even TWRP's built in file manager and all of which are granted root access by SuperSU but won't mount the system as r/w.
I checked with root checker and it says I'm rooted and all other root apps seem to be working fine. I also have an LG G-Pad 8.3 on kitkat rooted and a Samsung Galaxy S2 on Cyanogenmod 11 both of which can mount the file system as r/w and I've rooted a lot of other devices with no issue.
One thing that doesn't make a lot of sense is that none of the apps can mount system as r/w on my Z1 yet if I tell SuperSU to install itself to the system from its own menu it works with no problem.
I just need a solution to this issue and would rather not reroot it again as the root method for this device is a pita, it's also worth mentioning that I can't unlock the bootloader on my device to root it that way as my phone has "Unlock Bootloader Allowed:" set to No.
Thanks.

I'm not sure but it sounds like you're using an older version of recovery that didn't allow full root.
Try flashing the latest version of NUT's XZDualRecovery (Z1-lockeddualrecovery2.7.123):

Just upgraded the recovery. All went well but still having the same issue

@dan-youd
You can try this:
Download this UPDATE-SuperSU-v1.94.zip from chainfire, copy the zip on your phone reboot into recovery and flash it.

Just tried it now. TWRP wouldn't flash it because it wouldn't mount the system but CWM flashed it no problem. Got back into the OS and still same problem

Just reroot with bin4ry's latest root tool. It fixes the issue. Some roms still use the old root files where there's an issue when you mount rw, forcing your phone to reboot.
Sent from my C6603 using xda premium
I've tried rerooting with bin4ry's latest v30 root, but I have tried several times, but in Superuser app I get the same thing : su binary not found and then I've unistalled the Superuser application, and flashed from CWM the SuperSU.zip from Chainfire, now SuperSU is working, BUT I have the same problem : the phone reboots when mounting.
What should I do?
Thanks
Might not work but try binary v26
Sent from my C6603 using xda premium
Ok I will try it now.
L.E. : Thank you, it worked!
Yesterday was working fine, but now isnt working anymore the only difference is that I've installed through CWM the PureX soundMOD. Guess I have to reroot again? ) Any other solutions?
Solution :
adb shell
su
stop ric
then mount system with root explorer and delete /system/bin/ric
After that OTA doesn't work anymore.
Am I the only one who has this problem? Today after trying to paste an apk to system/app , forced reboot, and then another one after the SONY logo.
What should I do to get rid of this idiot problem?

Same problem here. Root Explorer to change R/W of /system, or copy a fire there make a reboot. Just re-root with Easy rooting Toolkit for XPEIRA Z SO-02E (ver 1.0.2) and works fine by far now, but not sure if it will happen again. (Rooted with bootloader BLOCKED)
I got another problem now, I've fully unrooted the phone with the SuperSU option, and now neither of rooting variants works. They stuck at here :
http://img803.imageshack.us/img803/8058/24461260.png
So no root with those methods, it worked by flashing through CWM the SuperSu.zip, but still I get forced reboots. I don't know what to do. Guess the only option is to do a full wipe, but I don't want to do that.

When you stuck there, try this: kill process adb.exe with task manager. Good luck.
Will try it when I get home. Thanks for the quick answers.
Not working : /system/bin/sh: can't create /sys/kernel/uevent_helper: Permission denied
Ok nice ...
Maybe I will reflash the firmware and do a full wipe, but I will stay like that for a while. Thank you anyway!

[Q][V][JB4.3] Keep root when flashing 9.2.A.1.199 with flashtool?

I can't find an aswer to my question anywhere, so I'm trying it here.
Phone: Xperia V
Does anyone know whether it's possible to keep root access when flashing the latest 9.2.A.1.199 firmware via flashtool over an older JB4.1.2 installation (rooted 9.1.A.1.140) when unchecking the "Wipe Data" and "Wipe Cache" options?
Or has anyone tried and succeeded? I'm reluctant to try myself as my system is running smoothly, but I'd like to update to 4.3 if possible. Only if I can keep root, though.
Thanks for your help!

That's good news! I assume that is how you managed to root your 4.3 on your TX?
I'm not really sure about that. Data partition won't be wiped but system will be together with su binary file from xbin folder.

Yes, that's why I was concerned. But Superuser also supports OTA survival, and it's installed in the user partition.

I kept my root not actually from 4.1.2 but after upgrading to 4.3.
Flash 9.2.a.0.295 using flashtool
Back up TA partition then unlock bootloader
Use the easy rooting guide:
Using flashtool, fastboot flash custom kernel.elf with recovery
Immediately reboot to recovery
In recovery, mount system then flash superuser update zip
Do not reboot but instead remove the battery
fastboot flash stock 4.3 kernel.sin
Reboot and restore your TA partition
Install scary alien root toolkit and save your root (read carefully the instructions)
Upgrade to 9.2.a.1.210 via OTA (not pc companion)
And that's it, you're in latest 4.3 and you're rooted!

Just one question, what to use to backup TA on .295 without root?
With the tool I found you can backup TA only if you have root.
Sorry, I forgot about that, if you're still in 4.1.2 you can easily root that, you can back your TA partition there and restore it later

There is no stock recovery on xperia phones
Only time it has recovery when you do an system update, after system update is done it gets erased as it has no use

If the newroot tool deletes the cmw recovery then yes it will
But if you unroot you will not be able to access recovery even if the recovery is still on your system partition because you do not have root ....

And how can this be done?

flash SuperSU from recovery, it should delete kingroot and install SuperSU on it and then restart, open the app and then update binary normal way.

for your Z1 use Nut's dual recovery, its the best and easy to install and there is lots of instructions available ! you can get the package from nut's website, (http://nut.xperia-files.com/ click XZDualRecovery -> 2.8.20 -> take Z1-lockeddualrecovery2.8.20-RELEASE.installer.zip NOT flashable and download it...
installing SuperSU delete the one you have, you need flashable version wich can be located here https://download.chainfire.eu/696/SuperSU/UPDATE-SuperSU-v2.46.zip
then just put it to your sd card and reboot to recovery, from recovery select install zip from sd card, select that supersu file you just put in there and install it, then just reboot and done.
Thank u soo much Migidid bro.....I followed the said procedure and successfully installed dual recivery and supersu, Thanks alot once again, i wanna donate..............love andorid...love sony
Just press thanks button and we're cool

[Q] Help needed: new Z1 owner, cannot figure out how to get rooted .283

Hey guys,
After hours and hours of searching forums and trying things, I decided I need help.
I just bought a Z1 (yes, they're still for sale) and I wanted to update the firmware to the newest .283 lollipop. Also, I want to root my device.
I have rooted Android phones before, and I have some experience flashing Custom ROMs etc.
As I have understood I have to downgrade to a 4.4 ROM first, to get root. Then my plan was to install recovery and install .283 Pre-rooted ZIP in Recovery.
So here's what I did:
-Flash 14.1.G.1.534 firmware
-Root using KingoROOT
-try to install recovery
-boot into recovery
-install pre-rooted .283 Lollipop ZIP
-phone won't boot anymore.
I am still able to flash the newest .283 with the FTF file, but then obviously it's unrooted. I also cannot figure out how to flash recovery after flashing .283 FTF. (Flashing recovery seems to work, but I cannot enter recovery via adb or otherwise)
So if anyone can tell me what I am missing, please do!
for what i know the ftf files can't be prerooted. so download a prerooted zip file and install it from a recovery. btw if u're gonna try any custom rom, don't forget to backup your drm before unlocking bootloader. That's a must for xperia devices
Thanks. However, I can't get Recovery to work after flashing Lollipop firmware. And when I downgrade and then flash the ZIP from recovery, the phone won't boot.
I succeeded! The steps that led me to this result:
-flash KK 14.4.A.0.108 in Flashtool
-Root the firmware using Flashtool/SuperSU method
-flash Recovery using Dual Recovery (http://forum.xda-developers.com/showthread.php?t=2647487)
-Flash the Pre-Rooted ZIP in Recovery
-Success!!
