What I did is while powered off, pressed start and then connected while holding back button
It took a while but it worked
I wanna read back the ROM from dayan tikshoret is case I flop but I don’t have the scare file to read back. Does anyone have it?
Just do a readback with mtkclient, no need for the scatter file.

Yes, would’ve done that but was on windows and had no patience installing Windows. Ended up using dd in termux…
Subject: Need help — building Android 11 kiosk ROM with working Google apps as system apps
Device: DuoQin F21 Pro (MediaTek MT6761, Android 11), bootloader unlocked, Magisk rooted.
Goal: Custom firmware where Google apps (Gmail, Drive, Gemini, Maps, Messages, Contacts, Gboard) + my own apps (ChatGPT, HebDate, Tfilon, US Mobile) are baked into /system/app/ as system apps. Phone must:
-
Skip setup wizard (no Google sign-in needed)
-
Have Play Store hidden but functional in background
-
Block APK installs, ADB, developer options
-
Survive factory reset — everything still works after wipe
Like Kosher phone vendors do (fig flip II, etc.).
What I’ve tried (all failed):
-
Direct injection of Google apps + Play Services into
/system/priv-app/via debugfs → boots, but Google apps say “device not compatible / update Play Services” because signature mismatch -
NikGapps, OpenGApps Pico → too old, Play Services 21.x, modern apps reject
-
Pulled current Play Store-delivered APKs (Play Services 26.15.33, all splits) and merged via APKEditor → APKEditor re-signs with its own key, breaks Google’s signature chain
-
microG (MinMicroG-Standard) → installs fine but no signature spoofing patch — Gmail rejects with “device not compatible,” ChatGPT bounces to Play Store
-
Tried to dump fig flip II (working kosher phone) via mtkclient → BROM auth-locked, handshake fails
-
UnlockTool → considered, didn’t proceed
Where I’m stuck:
To make Google apps work as system apps I need EITHER:
-
A. Signature spoofing patch for services.jar (microG-friendly framework) — don’t know how to build/integrate this for my specific ROM
-
B. A clean dump of a working kosher device’s
/system/priv-app/PrebuiltGmsCore/+ matchingprivapp-permissions-google.xml— to copy real Google-signed Play Services -
C. Custom AOSP build with sigspoof patched at source — no build environment for this device
What I need:
-
Anyone who’s done microG with sigspoof on a custom Android 11 ROM — how did you patch the framework?
-
Or anyone with a signature-spoofing Magisk module that survives factory reset
-
Or anyone with a
super.imgdump of fig flip II (or similar Kosher Android 11 phone with working GMS) -
Or pointers to paid services / freelancers who specialize in MTK kiosk firmware
I have the toolchain (WSL + lpunpack/lpmake + debugfs + APKEditor) and have done extensive surgical /system patching. Boots fine until Google trust chain breaks.

If anyone has a solution It will be really helpful for me. Thank you,
You are waaaayy over engineering/overthinking this

Do you have a easier solution?
I don’t know where to start
Look around the forum and on xda for how to install gapps and throw whatever AI agent you are using in prison. It’s just manufacturing issues.
As for kosher stuff, you’ll have to figure out the big stuff on your own. Alot of info is on the forums and you can ask specific questions.
The funniest part, and the reason why your AI agent should go to jail without passing go and without collecting $200

I have tried to searching on a few websites on how to install G apps, but most guides are only for open devices, my goal is that it should be in the OS and only run in the background, I don’t want the phone to actually have play store, only play services and some Google apps
Those topics have nothing to do with each other.
You’ll have to search around and peice together info, and also try some new things.
There is no direct guide to everything you want.

You can’t “have play store” and “not have play store”. Its either there or it isn’t. You have to bake it into your ROM like regular, follow guides and discuss this with your AI agent until it gets hoarse. DO NOT mention to it that you want to hide play store, this will confuse it. Tackle one thing at once. After GAPPS are up and running. Start a new conversation telling the AI that you want to hide the play store in a ROM that already has it. No need to mention that you added it. Compartmentalize your goals and tackle them one by one.

Whatever’s he’s using will not be helpful if he has to completely spoonfeed it to avoid those results. They are kinda funny.
I’m curious what model it is. It should know what it’s saying is nuts.

At least it should tell him to only paste it once.

In general, the forums need an AI policy.

@yossii to be clear, you’re not being made fun of. Your AI agent is. It’s completely misleading you down a path of total nonsense.

Too many new ppl coming in who never debugged before ai so their starting point is skewed. Ppl also believe AI can’t be wrong until they seriously break something.

But I’m trying to create an operating system like the F30, and I want to have some Google apps and I want it also to survive factory resets, so they have to be system apps, my problem was that my Current G apps has to Be updated After a factory reset Because they are a older version, but I want the Play store to be hidden so it won’t work
So can you give me some guides where to start what to look for
let me explain a little better,
I need to build a “factory-reset proof” ROM that has my Google and custom apps baked into the system. Everything needs to work smoothly after a wipe without needing Play Store updates or sign-ins. I also need to permanently block APK installs and Developer Options. Can you help me patch the framework and build the final image?
