PLEASE HELP With New Version of the Qin F21, Different Hardware and ROM

Phones Qin F21 Pro
523

Would be better if you get exact version so you don’t make mistakes. I don’t know forsure, but lowest I believe this for this phone came with is 2.7 (something like that) and latest 3.0.2

Can you please send partial serial number?

Old ROMs are not compatible with this phone. Treat it as a new device. Majorly different hardware.

I patched services.jar to lift their adb restrictions, background app kill fix, and also have an MDM removal script for duoqin’s device admin.

Will send duqin admin removal script privately if you want. Or maybe I’ll just publicize I dunno. Have to ask.

Do those two and you’ll have a ROM (no gapps). You’ll need to add gapps if you want them.

This will give you a new “1.1.1” for the new phones.

Thought you were done with this after the last one, eh? Lol

524

so I guess you don’t have a version of your ROM

So what did they change about this phone?

525

Dunno what that means

All vendor differences here:

And no, just adding these did not help. System and product are still incompatible.

You are welcome to try and figure it out, I definitely won’t be :slight_smile:

I’m happy with there being an unlocked new ROM available.

526

Can you email me the script please thanks

527

First you gotta root the phone.

No telegram anymore? I tried sending you a message

528

Not on me I’ll check later thanks
If you don’t mind I’ll text you later for instructions
Thanks

529

Deal, but one condition, when we are done, you pull the super and send it to me.

I’d do it myself, but I’ve got an original and can’t really test.

Dunno when @dfrydman will be back around and I want to avoid many bricked phones.

530

But this method won’t get the phone bricked correct?

531

No

532

Once a phone is bricked you can’t reverse it?

533

You can

534

How do you flash TWrp on this new version what partition does the recovery reside in?

535

You don’t, as of now.

Why do you need twrp?

536

Much easier to install gapps packages through a zip file in TWRP or at least this is the way I know how to do it it might be other ways

537

With the very first versions of the Quinn phone I used to flash the phone with the firmware with the TWRP and then flash the USA bands all done with SP flash tool.

Then after that I would flash a gaps package under TWRP and voila all of the bands were there on the phone and the gaps packages there was a couple of more steps one was to get the IMEI flashed and then the Gap package approved by Google it was a process but at the end I had a working in USA phone.

538

So right now I have a fully stocked version of the new one and I would like to get it working in USA with gaps

539

No available normal ROM as of now, and you’ll have to flash stock, root, remove MDM, replace services.jar, then add gapps a different way, or try hovotek, though I doubt it would work.

540

The bootloader is unlocked so the possibilities are there just looks like everything has to be done manually for now just a lot of work to get one phone to work but eventually I suppose somebody has to make one

541

So of course I unlock the bootloader and this phone will constantly reboot

542

Dm verity error?
