Android 10+ system file r/w access

Hi what is secret to using file manager on phone Android 10+ with su access to read and write in system - remove bloat apps? I have su access, but I read in 10+ file system not allow from file manager, only need use adb. How to use file manager with su to remove manually on Android 10+? I get error when deleting app from any file manager with su access "cannot delete". Danke.

Well, i guess that i can reply your question. It seems that we can't mount R/W due to Google's use of dynamic partitions for new version android devices.
However, we still have a way to fix it. Use su permissions and dd command to export those partitions which you want to modify (for example: system, product, vendor, and oem, but oem special), unpack and then repack, at last reboot you devices into fastbootd mode and flash back those partitions into you devices. reboot, now, you can R/W those partitions .
if you need to edit oem partition. You need edit a file in vendor partition firstly. Export and unpacking vendor partition. Finding a file which called "fstab.qcom". Open it and delect（,avb_keys=/product/etc/security/avb/oem.avbpubkey）code inside. Repacking and flash into you devices again. After this, the repackaged oem partition can be mounted correctly by flashing it again otherwise the oem partition can not be mounted (no files inside).

Wow very complex but thank you for explain!

Apparently my phone has no system partition

I have a CUBOT Note 20 Pro (rooted) and today I tried to install the android 11 GSI when I got an error saying "FAILED (remote: 'This partition doesn't exist')" when trying to flash using the fastboot command line and this command specifically "fastboot flash system system.img". I looked around the scatter file and there seems to be no use of the system.img file whatsoever.
I have attached the scatter file and a screenshot of the error.
Any help would be highly appreciated.

How exactly do I use this tool?

read back super.img from SP Flash Tool, patch it, replace system.img, whatever, and flash new super.img back from fastboot

Can you explain the steps a bit more? I'm really new and have no clue how to do this.

sorry apparently TWRP is required, but you can also use official tools on PC

So, lets review the steps:
1. Unpack the super.img using the links you provided
2. Modify the system.img inside the super
3. flash

another approach is DSU Loader from Developer Options
DSU Sideloader lets you easily boot any custom GSI via Android DSU Loader
DSU Sideloader is an open source app that greatly simplifies the custom GSI installation process of the Android DSU Loader. Check it out!

Question Why can't we flash to vendor?

Trying to flash twrp adreno drivers gives this error despite having enough space in /vendor.
Anyone knows why?
RUI 3.0 LiteOS has custom drivers pre-installed. Looking on how to do this.
Thanks.

Like i said on the original post... drivers.
So I don't need to use Magisk and Overlayfs.
Overlayfs is unstable for some apps.

Method 1
Extract .ofp file use simg2img to make a single sparsed Super image and then use lpunpack to open Super.img and get all extracted partitions like my_heytap , my_stock , system , vendor and product , then edit the vendor .img file and then repack all partitions using lppack
​Method 2
Get vendor.img (Firmware.zip >firmware.ofp>super.img>vendor.img)
Modify it and repack it as newvendor.img
in fastboot mode do , fastboot erase vendor then fastboot flash vendor newvendor.img
Also before flashing this modified partition ensure that you have TWRP and have disabled vbmeta verification on all three vbmetas partitions​

After connecting to a PC and making a copy of any partition, an error is displayed:
"Reading" boot_b ".img: Pulling" boot_b ".img: ADB: Error: Failed to Stat Remote Object '/Sdcard/boot_B.img': No Such File or Directory"
There is no "boot_b.img" file on the card on the smartphone card (OnePlus8pro), no pop-up has erected in Magiska to give any root permissions.
What am I doing wrong?

How To Guide [TB-J716F] Flashing Pseudo_Global firmware (many languages inside)

If you not like ZUI firmware - you can flash Pseudo_Global to your tablet. I've tested this way and sharing it here.
Pseudo_global fw was built on ZUI, it has A11 inside and you never can to get some system updates - no one is doing them.
Your data will gone away.
YOU ARE WARNED !
And so:
I've tryed this on ZUI 14.0.127 with unlocked bootloader and active slot _a. Active slot can be checked with
Code:
adb shell /bin/getprop ro.boot.slot_suffix
and answer must be _a
If not, you need change boot slot with command in fastboot mode:
Code:
fastboot set_active other
And now you can reboot in EDL mode and start to flash all needed partitions from unpacked archive Pseudo_ROW_J716Fl.7z
You need unpacked ZUI 12.6.211 from lolinet https://mirrors.lolinet.com/firmware/lenovo/Tab_P11_Pro_2021/TB-J716F/ for working with QPST Partition Manager.
How it looks you can see in this video:
You must flash ALL partitions archive contains. Files in Add.rar not need, it for any case.
MANDATORY ! After flashing you need at first to boot in recovery and make reset to factory settings, it will format userdata. Without this action you can't boot.

It was exactly what I was looking for and trying for days, but following your tutorial I still couldn't, it didn't turn on, I had to upload the rom 12.6.211 again. I wanted to leave it with multiple languages.

OK, I will re-check it in 2-3 days. Although I think you did something wrong.

Dude, I have some bad news for you. Your hands are crooked. That needs to be fixed.
My method works without fail. It only takes half an hour.
Try it again.
