ROM] [P] [9.0.0] Velocity Shamu

No single problem with 25.12 build and 8.1 gapps in the folder, everything runs flawlessly.
If any have problems, problem is for your side.

I know that the problem is on my side, I cleaned everything even the memory but the gapps do not install

What error message are you getting?

no error message. It installs everything perfectly, after the restart no gapps,
Only with 8.1 with 8.0 no problem.

Whats youre installation procedure.

Restore backap stock(N6F26Q)Vipe dalvick cache,cache,system ,data,install ROM, install gapps.

Ok, not sure why youre messing with stock....

Process is

1. Make sure you have TWRP installed
2. Reboot to recovery
3. Factory reset
4. Wipe system
5. Flash Rom, GApps, Magisk
6. Reboot

Nothing more, nothing less. DO NOT manually wipe partitions. Especially data.

I tried so and nothing gapps ??? Strange.

My guess is its something to do with flashing stock at some point. I would back up your SD card on your PC and wipe everything. Reinstall TWRP and move everything back over. Then follow these steps. Something got very screw'd up somehow. GApps dont disappear on reboot.

I am now with Velocity 8.0.0 on October 14th, how should I delete everything? and reinstall the TWRP?

I tried to erase the internal memory, it did not work.

I guess seek out help on XDA. Whatever you have going on something is very messed up. If you made it all the way back to a clean flash of 8.0 you should be able to just follow the exact steps I stated above.

Process is

1. Make sure you have TWRP installed
2. Reboot to recovery
3. Factory reset
4. Wipe system
5. Flash Rom, GApps, Magisk
6. Reboot

Dont do anything else or wipe anything else.

I deleted everything from internal memory, with NRT I installed the stock (27h) I made a clean installation as you wrote above and the gapps do not install.

Here is a screenshot.

On your screenshot, gapps is installed fine, without a problem.Where is the problem?

The problem is that after the restart are not there?

May I ask wich version of twrp have you instaled?

3.2.1.0

Did you sign up in Google acount after boot or skip it?

the rom yes lights up immediately and does not ask for any account, when you start there is no play store there is nothing, a rom without gapps.
