I have never been able to get the FOD work consistently on any of the custom ROMs. Have flashed the right vendor/firmware for my region. The FOD is very erratic and often times i need to rely on the number lock. I have tried flashing other vendors/firmware but that only worsen the situation

UPDATE:

Just flashing the Vendor from Akhilnarang would not entirely work. I fastbooted the Stock stable ROM and then without wiping the vendor flashed the custom ROM. It is way more responsive now
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] alex9yust:
Now there are ROMs in which a personal vendor. Oxy, there is a PA build with its vendor, Mokee. there are other ROMs that I will never try to install on my phone again after I got problems with the scanner and encryption.

After them, it is necessary to flash the miui via fastboot/MiFlash, sometimes with flash persist.img and start the miui, so that it configures the sensors. it’s normal for me. only it has nothing to do with the ROM, and I seem to have said this before.

Hi - nice to see HAVOC exist for 9t Pro :) ( coming from HAVOC on OnePlus 3 )

few Qs I hope the HAVOC community can please answer:

Does FP unlock work when the screen is off ? ( while AOD is DISABLED )

Does FP direct unlock ( i.e w/o additional need for PIN/swipe unlock as well ) works after boot ( is there an option in HAVOC's settings ?)

What's the rom's built-in kernel's "name" (Immensity/ F1xy etc...) ?

Did anyone tried the screen's refresh rate overclock mod on HAVOC ? which mod (Hz speed) ? using what kernel ? any disadvantage beside the obvious danger the the screen's life ?

Thanks for the wonderful rom releases - and your answer :)
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Sumit Samanta:
Anyone flashed ?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] alex9yust:
1. no. we do not have the implementation of gestures on the screen is off.

There is an implementation (in lineage, there is a module for magisc) when you need to get into the scanner area on the screen off, but this is also a crutch, it will not always work (now this should not work in the last test build). and to me personally it’s not interesting at all.

2. also not, it seems. at least I do not see this setting. and even when it was in ROM, I personally did not use it. because of this setting, they often complained about security issues for applications that matter. and to enter pin once at boot time is not a big problem.

3. F1xy, only I build with lower core frequencies.

4. it’s not interesting for me either, I can’t say anything.

Flashed the 07.03 without gapps. Everything is ok, except for 2 things:

1. The Mobile data APN settings for my carrier (Telekom Romania) diasppeared and the OS doesn't let me save new APN settings. On vodafone it works fine. So I can't use mobile data for the moment.

2. A bug that seems to be related to the OS, but appeared in one of the previous builds: Turtl app crashes when I try to login and gives an error: "os error 88"

3. A third, but less important bug is related to the default phone app: in call history, if you delete an entry, they only appear deleted after you close and reopen the app (this was not a problem in Official Havoc builds I have used previous to this one).

EDIT: I tried to reflash the 25.02 build, did not boot, then reflashed 07.03, now the APN works. I don't know what caused the problem. The other 2 problems remain.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Planet X:
Just flashed this build over ExtendedUI and everything is still working great. Really nice rom with a lot of extra features. The haptic feedback is stronger too. When I would flash latest Immensity kenel I would have to choose the Mi9FOD version for this rom? Or is this F1xy kernel the better choice? I thought it was EOL?

Edit: tried Immensity with Mi9FOD and fingerprint is less accurate with That kernel. So flashed back to F1xy.

B.t.w. I miss some fingerprint icons to choose from. Will that be added soon?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] gps3dx:
Hi all,

Did anyone managed to bypass SafetyNet (got 'basicIntegrity' AND 'ctsProfile' GREEN in magisk) on this HAVOC rom ?

Did you used "MagiskHide Props Config" ? what config did you set ?

Lastly - is it possible to bypass SafetyNet on HAVOC with a DISABLED force-encrypted device ( aka DFE ) ? ( can dm-verity stay enabled even when using DFE ? )

Can anyone please write a small flashing guide - i'm confused as some report that vendor needs to be flashed after rom and some before... some states various methods for performing the DFE: some gets dm-verity to be disabled some not...

THANKS.

Hi there,

after flashing last build, the phone directly boots to recovery and data can't be decrypted. Is there anthing i can do?

Thanks in advance!
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] alex9yust:
for me safetyNet works without and with magisk. I do not use modules to correct the signature.

about DFE - I will look later, I never used it practically.

there is no difference in which order you will flash the vendor and ROM. the difference is important if you are flashing DFE to remove encryption. First you need to flash the vendor, then DFE. because DFE fixes fstab, which is in the vendor. and if you are flashing a new vendor, then you need to flash DFE.

There is an instruction in # 1 post, I flash it so hard and often. except that I do not flash vendor + firmware at all, I flash miui via fastboot and vendor stays after miui.

if you want to remove encryption, then the second paragraph should be like this

2. flash DFE, reboot from twrp to twrp to be sure twrp read the new fstab, format data-yes. reboot in system
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] alex9yust:
ok, I tried, it works for me.

I really don’t understand why you remove the encryption, but if you want, you need to flash DFE, reboot twrp to twrp, do FORMAT DATA-yes, boot into the ROM.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Planet X:
That really works. Finally the rom feel so smooth now.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] CreaB:
HI there,

i dont removed the the encryption. i flashed the rom like always and suddenly the encrpytion was gone. I really need the files on, so is there any way to get them back?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] alex9yust:
yes, in a previous post I removed encryption, safetyNet works without and with magisk.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] alex9yust:
the only thing I can do is try to repeat. what build did you have before? but usually I put the previous build, update to the latest and I never saw encryption problems.

I don’t think you can recover.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] CreaB:
Hi there,

i fixed it by my own as follows:

Via sideload i reflashed the earlier version of this ROM and also the former installed fw+vendor.

I know was able to boot up again.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] alex9yust:
if you changed vendor + firmware, then it is not surprising that you have encryption problems. It’s great that they returned everything back.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] CreaB:
Hi there,

just to clarify: i have not changed vendor or anything else. I simply (dirty) flashed

Havoc-OS-v3.3-20200306-raphael-Unofficial.zip

over

Havoc-OS-v3.2-20200225-raphael-Unofficial.zip

nothing else.

Hi again,

so i tried the names build (Havoc-OS-v3.3-20200307-raphael-Unofficial.zip)

and the same happened again. So i flashed the fw+vendor i am using at the moment (fw-vendor_raphael_miui_RAPHAELGlobal_V11.0.3.0.QFKMIXM_cebc52c10a_10.0.zip) and all is fine again.

Should this be needed? Am i doing or using anything wrong?

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] .HeadLess.:
hi there!

I tried to flassh 0307 and safetynet not passes integrity ok but cts profile fail, no matter how hard i tried..

as you wrote in the first post.

-update firmware/vendor to "fw_raphael_miui_RAPHAELEEAGlobal_V11.0.5.0.QFKEUXM_fcfca69317_10.0"

format system, flash 0307 zip

reboot to system

flash gapps. (at that point flash magisk20.3 is failed) it seems like system partition is renamed to system_root maybe this causing my issue?

and safetynet fail.

i don't know what i'm doing wrong it just started as an upgrade from havoc 3.1 build but for now it's a pain in the ass.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] crimsoncrow:

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] alex9yust:
remove the system mount that remains after flashing your gapps or reboot twrp and flash magisk. for some reason the magisk cannot do this ...

about broken SafetyNet - I don’t know why it doesn’t work for you, as I said above, it works for me with and without magisk.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] alex9yust:
you can look in the zip ROM, look at the installation scripts there, and if you find something that changes vendor or firmware, then I will take my words back.

I can only assume that you have something installed in /system/addon.d, but this is only an assumption. I just don’t know what else can change your vendor + firmware.

and what twrp are you using?

Hi there,

I just recognized that i got the problem of missing APNs too. I tried to re-flash the last build, but without succes.

Is there anybody who has a possible fix?

Thanks in advance!

[EDIT]

Because of the problems i had with un-decryptable files, i formatted data after a full external backup and reverted to fw-vendor_raphael_miui_RAPHAELGlobal_V11.0.2.0.QFKMIXM_6050442ee4_10.0.zip. After flashing this ROM version again, even the APN problem is gone.

[/EDIT]

[EDIT]

So after recognizing that the APN problem is back again, i decided to start over and used the latest stable global fastboot rom to install MIUI 11 and start from scratch. After doing so and installing the last version of this ROM, the APN problem is back. after a reboot there are no APNs and i have no mobile data connection. It seems that there is something wrong.

[/EDIT]

[EDIT]

So APN problems seem to be totally random. Sometimes after a reboot APNs are ok, after the next they are gone. Really weird..

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] CreaB:
Hi there,

encryption seems to be related to fw+vendor. Using an "oder" one, it's ok. I Alis dont know whats the point with APN, maybe it is related to use of dual sim. If i take them out and put them back in, APN settings are back like magic.

As i starte over with a clean device, with Miui, i guess i have to try another ROM now.

There was an option for customizing swipe option in messages so that we can configure what will be done after swiping a message, we can configure delete, mark as read or move to archive etc action from there.

But I can't find the option in havoc 3.3 (unofficial with GApps - Build Date Thu March 12 04:12:21 +03 2020).

Also, I loved the option of automatic call recording in havoc os, but it is not present now in there in call settings-

[MENTION=4206648]alex9yust[/MENTION] why EOL? It's a very good rom.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] valentinc22:
There are a lot of things that are wrong with this ROM, as stated by me and other users. Given the fact that it's End Of Life, most likely none of the bugs that are specific only to some users will be fixed. The developer stated that many times. He stated that in his device, everything is working just fine (and I suppose maybe in ours it could work fine if we do some clean flashes, but that takes time which probably most of you do not have).

I personally experienced a total lock of the operating system a few days ago when I was talking on the phone and tried to install an app at the same time (in which even a restart won't bring it back, the system would load, but none of the icons appeared on deskop and none of the buttons worked), the point where I decided to go to Lineage OS 17.1, which is exteremely similar to Havoc. The only thing that I am missing is the Smart charge feature, which Lineage does not have, but it's not the end of the world. The fingerprint works the best I have experienced so far in Lineage.

I was using Havoc OS since buying my Redmi K20 Pro and I can tell you that the support for this device was very poor right from the start: the developers that engaged in making the builds did not have time to do them regularly or investigate all the bugs that were reported. I was personally disappointed, but hoped for the best. Since January 2020 there is no official Havoc for this device and probably will never be. So if you want to try the ROM do it, but I would not recommend it if you are using the phone as your daily driver (as I do).
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] CreaB:
Hi there,

I simply can confirm this. As i really like the phone and the ROM, i have switched to another Unofficial build and i am really satisfied so far. I am aware that this builds may end at any time, if the creator may not have time or anything, but so far it is usable as a daily driver.
