Philips 55OLED854/12 - Android 9 - Write access permision - Philips, Sony, TCL Android TV

Hi,
I've updated system on my TV to Android 9 and lost write access permission. Before update I was able to move / copy / delete files from my external USB drive with NTFS file format. Now I can't even enable write access permission on any file manager...
When I'm trying to grant Write Permision i have the following error:
"This device does not appear to support the Android Storage Access Framework.
(Error: ACTION_OPEN_DOCUMENT_TREE not implemented by device.)
Is there any fix / way to resolve it?
Thanks,
P.

Hi,
what was the firmware version before you did the upgrade?

[Q] Adfree app?

Sorry my bad English. I install AdFree app.
"Update Found!
New Hostnames..."
I klick 'Download & Install Hosts'
then "Error
Failed to replace your hosts file. Error message:"
What I do?
As far as I'm aware, the Adfree app cannot automatically download and install the new hosts files because we have no write access to /system when the phone is fully booted.
You would need to push the file manually via ADB whilst the phone is in recovery.
See this thread for further details.
Regards,
Dave
Or ask your Cook to implement the host file being symlinked correctly so AddFree can work off the bat.
Modaco Rom's have this and also include AddFree.

[Q] Lost access to internal storage

Hello,
In the process of rooting and trying to install CWM Recovery in preparation to flash Cyanogenmod, I seem to have denied myself access to the phone's internal storage. In the "File Manager" app, I get the following screen:
Local: /storage
No files
No search results
In addition, any app that requires access to internal memory will not work, instead showing messages such as "Try again after scanning media files" or "Not enough storage". If I plug in the USB cable and set it to "Media sync (MTP)" mode, Windows Explorer will show the device but list the internal storage as having "0 bytes" and no files.
I already tried the following:
- Factory reset
- Flashing the official ROM through the Windows Enabler / UpTestEX tools
In both tries the phone was "reset", as in it returned to the initial Android welcome screen where you set up your Google account, but in each case I still didn't have access to internal storage.
This is what I have in the "About phone -> Software information" option:
Android version: 4.1.2
Baseband version: APQ8064T/MDM9x15M
Kernel version: 3.4.0
Build number: JZO54K
Software version: E98810b
The phone does not have Wi-Fi access either, which is why I was tinkering around with custom ROMs in the first place, so I won't be able to download anything to it as part of the solution.
Is there anything else I can try?
I'm guessing you used FreeGee to install CWM? Perhaps try restoring?
If that didn't work... Id move the EFS backups to my computer. I'd make a NAND backup in CWM. Then I'd get CM and gapps on a micro SD. I'd do a format of system, data, and cache. Then I'd install CM and gapps. Then I'd cross my fingers.

ackliph,
Since I didn't have Wi-Fi access on the phone, and at the time I didn't know how to reverse tether it to the computer, I was looking for a procedure to install CWM Recovery that didn't involve downloading files directly within the phone (only transfering via USB). Right now I can't find the exact instructions I used, but it was similar to what is described by hkfriends in this thread: http://forum.xda-developers.com/showthread.php?t=2361941, the only difference being that the image I downloaded was not that one.
I rooted the phone with Universal Root, then followed those instructions to install CWM Recovery. It seemed to have worked, but when I rebooted... nothing happened! The phone booted normally, and if I tried entering recovery mode all I got was the stock LG recovery.
I continued looking for another way to install a custom recovery, but instead came upon instructions to flash KDZ files with UpTestEx. Since the immediate problem I was trying to solve was the lack of Wi-Fi access (and not really the custom ROM), I thought it couldn't hurt to try updating the stock ROM. The procedure did update my ROM, but I ended up in my current predicament: no access to internal storage, and still no Wi-Fi access! It even managed to unroot the phone.
So your suggestion would be to try installing CM via a microSD card. OK, I can get a microSD and try that. However, I do believe I will need root access to do anything of the sort. I tried Universal Root again, and got the following messages:
Beginning Root Process
/system/bin/sh: can't create /sdcard/G_security: Permission denied
Now change from Charge Only to MTP
No need to disconnect USB
Press Enter after making the change.
adbd cannot run as root in production builds

If uid=0(root), gid=0(root) is displayed
Press Enter to Continue

failed to copy 'Superuser.apk' to '/system/app/Superuser.apk': Read-only file system
Unable to chown /system/xbin/su: No such file or directory
You are now properly Rooted.

Evidently, that didn't work.
I guess I will need some other method of rooting it.

Google PlayStore "Waiting for Wifi" FIX (ROOT Required)

From March2017, Mi Max (and other Phones Running Stable Rom Miui8.2 on Android 7) + (Developer ROM 7.3x) (Global or China) when received latest update of Google Play Store; results in WAITING for WIFI sign whenever you install or update any app.
This error appears even when you are connected to wifi.
so basically playstore become null.
Requirement
1. Rooted Xiomi Phone (MI MAX hydrogen / helium) ( Redmi XX)
2. Running on Developer/Stable Rom Android N
Fix
from https://forum.xda-developers.com/galaxy-grand-2/general/trick-stop-play-store-self-update-t3495485
1. Create Two Text file on your desktop pc and remove .txt extension
---- "com.google.android.gms-1" and "com.android.vending-1" (without Quotes)
2. install root xplorer or any Root file browser app in your Mi Phone ( you may use APKPURE )
3. connect your device in mtp mode and paste the create files in internal storage
4. put phone on airplane mode
5. uninstall updates for Google Playstore
6. open root browser
7. grant root browser SuperUser writes and copy those two files from your base internal storage and paste them in data/app folder.
8. if it asks overwrite, grant permission
this will keep PlayStore from getting selfupdated and you wont get error.
this is temporary fix until Miui Roms get actual fix

Lenovo TB-7504F/X. No way to unlock bootloader and root yet?

Hope I created new thread in right path. As by title, I found nothing about this 7'' tablet . I tried to unlock the bootloader with the command:
fastboot oem unlock-go
but it returns:
failed (remote: unknown command)
Meanwhile, I found nothing about a TWRP for this device. Are there chances that something will be developed? Is it a question of time? Thanks in advance.
i have the same problem. No one help us?
im trying to root mine so i can get the proximity sensor locked. I am building a tablet install in my RX8, using this tablet. However as soon as I pop it in the housing the screen has a mind of its own, sometimes it works sometimes it makes me want to smash it up
Systemlessly Root Lenovo Tab 4 7 TB-7504X
Hello all!!?
Here I will guide you to root Lenovo Tab 4 7 TB-7504X with the chipset MT8735B and Android version 7.0 that also systemlessly!! So let's get tuned into the Step by Step Guide...?
Firstly, I am not responsible for any kind of demage caused to your phone!!
Actually there are two methords of doing so...
Moving on to first one (Simplest),
You need to download latest version of MTK Easy Su v1.0.6 and the Magisk Manager specifically v7.1.1 I will provide link for both of them below...
Install both of them...
Now Firstly open the MTK Easy Su apk and just tap on 'Activate Bootless Root' if it says 'Exit value 0' in the Log section that means you have Root access on your phone...
Note:- Don't try to update Magisk or Magisk Masnager or Set environment for modules to work properly in Magisk Manager, else you will brick your phone
- Don't update Magisk Manager Directly from the apk
- The following process is done on lock bootloader so be carefull.
- You will have to Open the MTK Easy Su apk and tap on 'Activate Bootless Root' each and every time you Reboot your phone...
Pros:-
- Systemless Root
Cons:-
-Will not be able to Update Magisk Manager or Migisk itself
- Will not be able to install Magisk Modules
Second Method:-
For this to work on your phone you need couple of apks and Files...I will provide all the links at the end of this post...
Again, I am not responsible for any kind of demage caused to your phone!!
- Firstly, You need to download an apk named 'init.d Scripts Support' and also need to know your phone's architecture i.e 32 bit or 64 bit if you don't know just download any apk like CPU-Z or anything like that and note your phone's architecture...
- Now, you need to create an folder named 'init.d' in your phone's internal storage and again create another folder named 'bin' inside the 'init.d' folder
Now, you need to move some files in these folders to gain Root access...So let's move on...
- Firstly, Unzip all the Files...
- Open folder named 'magisk-boot' and copy the file named 'magisk-boot.sh' and paste it in 'init.d' folder
- Moving on to next file, then open folder named 'mtk-su_r22' then open the folder based on your phone's architecture i.e 'arm' or 'arm64' (For 32 bit architecture open 'arm' & For 64 bit architecture open 'arm64') and copy the file named 'mtk-su' and just paste the file inside the 'bin' folder of 'init.d' folder
- Moving on to last file to copy, open the folder named 'Magisk-20.4', then open folder named 'arm' there you will find 3 files here, we are just conserned about 2 files named 'magiskinit' & 'magiskinit64'. Just copy one of the two files based on your architecture (If 32 bit then copy 'magiskinit' & if 64 bit just copy 'magiskinit64') and paste it in 'bin' folder of 'init.d' folder. The one who have 64 bit architecture need to make a small change in the file 'magiskinit64' we just copied to 'bin' folder. Just rename the file and remove '64' written behind the file name.
Now your 90% of work has been completed!!
Now install the latest version of 'Magisk Manager' currently v7.5.1 is the latest.
- Now open 'init.d scripts support' apk and check the 'Run scripts at boot time' option.
- Then set 'Execution delay' to 'No delay'
- Now tap on 'Selected folder' and just locate the 'init.d' folder and select it.
Note:- Please let be the option 'Try to acquire root privileges' Uncheked!!
Lastly Reboot your phone and after Rebooting open the 'init.d scripts support' apk and just tap on 'Run scripts now' it will show 1 File selected and then it will Show 1 File Executed'!!
Then just tap 'Show last execution results' (You may need to watch an add every 24 hours) and if it shows 'client: launching new main daemon process' at the very least of the execution results...Congratulations!! Now you have got Systemless Root on your Lenovo Tab 7 TB-7504X successfully!!
Note:-
- Don't Mess around things you don't know on a locked bootloader or you would brick your device
- Don't update Magisk via the apk itself
- Be Carefull while installing Magisk Madules on a locked bootloader
- You will have to Run the init.d scripts support apk each and every time you reboot your phone to have root access enabled
