Hi there,

I'm having trouble installing nethunter on my 6.1 and I'm not sure how to troubleshoot. I've followed the instructions above and got a working lineage 18.1 system. Magisk appeared to be installed and working as well (installed in boot and app.) After flashing nethunter, reboot system puts me into fastboot mode. I reboot again and it just hangs at the androidone screen. I can still get back into fastboot mode and "fastboot boot twrp-3.4.0.img" still works as well.

The output of the kali install doesn't show any signs of having an issue. I tried finding /proc/last_kmsg and it doesn't seem to exist. Likewise, /sys/fs/pstore/ seems to be empty.

Is it likely this is from using the lastest versions of lineage and magisk? I'm on magisk 24.1 and lineage-18.1-20220125-nightly-PL2-signed.

Any ideas?
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] yesimxev:
I'll try to reflash from stock and let you know how it goes. Most likely Magisk 24.1 (beta?) is the issue. Try a 22.0 or 23.0. I used one of those when made this guide @aeeaan
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] aeeaan:
@yesimxev I guess magisk 24 and 24.1 came out in the past week. I'll give 23 a shot.

I wiped cache/data and flashed the lineage recovery over boot and it does boot up now. Kali doesn't work as root is gone, but it's there. Going to try repatching boot and reinstalling magisk, then nethunter before I start from zero with the older magisk. Not sure if that's a sane approach or not, I haven't modded an android system since before they switched to the whole A/B thing and got rid of the recovery partition. Thanks for looking into this, I'll update tomorrow with how I did.
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] yesimxev:
I just did a full clean install with LOS Recovery without any problems, will update the guide so we don't needmessing with TWRP
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] aeeaan:
@yesimxev

Thanks so much! I wonder if I screwed something up. I didn't restart from a clean install yet, but once I got magisk installed again nethunter started working in what I assume is lite mode. Once I reinstalled Kali it would hang again.

Just to verify, lineage recovery doesn't actually work 100% on this phone, correct? It boots and adb can detect it's in recovery but the screen is blank. I found a ticket about this at lineageos gitlab that i believe is still current. Did you use adb and fastboot commands for everything or is your phone not affected? No need to reply I guess I'll get my answer with the updated instructions.

recovery on PL2 (Nokia 6.1 2018) only boots to black screen. (#4170) · Issues · LineageOS / issues / android · GitLab

Expected Behavior After flashing the lineage recovery via "fastboot flash boot $recovery" and rebooting to recovery I expect the recovery screen...

[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] yesimxev:
LOS works like a charm. The above issue you say is with TWRP. See the screenshot
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] aeeaan:
Yeah, I get the same black-purplish blank screen with both lineage recovery flashed to boot and TWRP set up as ramdisk :( There could be an undocumented hardware revision/different panel. That gitlab bug is about lineage recovery not TWRP.

I don't think this helps me, but interestingly, the TWRP ramdisk setup works perfectly with the Nokia android 10 stock boot image. No purplish screens. I stupidly didn't do any backups before I got started so I got Nokia stock partition images from this thread:

https://xdaforums.com/t/guide-how-t...tore-stock-stock-patched-images-here.3889815/

It's time for me to try this from the very beginning. I'm starting to worry that whatever the difference is between our phones might be what was causing my hangup. Which would mean no custom kernel for me.

EDIT: There are also a few comments about the display in LOS recovery here:

https://xdaforums.com/t/rom-11-0-official-lineageos-18-1-pl2-drg.4177467/page-11#post-85959839
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] yesimxev:
Interesting, I've seen your previous link too, that it's not TWRP. I had working Nokia 6.1 and blank screen with TWRP. So this one might be working with TWRP too. My clue is that when you have Android 9 on it before LOS, it's all good. If you have Android 10, it's going blank. Which version did you have?
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] aeeaan:
I started from android 10. But I foolishly didn't back up my phone before installing lineage the first time. I'm sure I can locate a zip with all the partitions in it if I look, but for now I just have android 10 system/vendor/boot.

Does lineage not replace every important partition on the phone? If not, I'll certainly hunt down an android 9 firmware and try starting from there.

Maybe I'll poke around the sources mentioned in those threads, see if I can come up with a code diff that someone else might find useful. I've never built android/lineage before, could be an interesting project for me to do this week.

EDIT: Started from a pristine LOS install and I ended up in the same place as yesterday. I'm going take a break to 1) replace my macos install with some linux distro because the performance of my 2015 has been driving me mad lately and then 2) see if I can track down the relevant source code to the LOS recovery purple screen I'm getting. Not sure I can, C/Android/Driver dev isn't really my thing, but I know how to read a diff :)

EDIT2: This is disappointing but I don't see my specific 6.1 variant TA-1068 mentioned on lineage's 6.1 page. I hadn't noticed this before, way at the bottom of the phone specs they only list 2 of the 5 or 6 variants. I mean, who wants a phone w 3 gigs of ram when there's a model with 4. I guess it just means they didn't test this model and it may or may not work perfectly. Another variable to consider :(

EDIT3: Well, I thought it was the European version, but I think it's more likely this is the Chinese/Taiwan version. TA-1054. They all have the same specs outside of the radio bands.
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] yesimxev:
That's a pity. Yes official files replace covers partitions. Anyway if that doesn't matter, you can easily downgrade with OSTLA to Android 9. There's also a region change service by @hikari_calyx but I'd try downgrading first
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] aeeaan:
The phone is in English and was sold on ebay as a global phone. Unfortunately, there's no model number to be found on this thing and android only identifies it as Nokia 6.1. I tried 2 apps from the marketplace and still only got that. In any case, thanks for your help. I'm going to take a few days off from this before I try again. I bought this phone to be a dedicated nethunter learning device so I am not ready to give up.

You could delete the old files first. So delete the rtl8xxxu folder, you can then use the patch which adds the new rtl8xxxu folder. You can skip the parts which patches the makefile and kconfig. It should work then, as makefile and kconfig would be the same.

I had Bepes ROM and PhamQuangs ROMS they were brilliant. The reason being they sped up the TC. I need/would like to do the same to the Diamond. Could anyone recommend the Fastest, Cleanest ROM? I am happy to install programs as and when I want them. It seems the more programs the slower it is. Seeming as this ppc has no external SD card we need to be really conservative!

No "We" do not not need to be conservative at all. Just treat the \Internal Storage folder in exactly the same way as you would treat an SD card on a device that has one. Or to think of it another way. Just imagine your Diamond is your old device but it has had the SD card glued into it. No need to be conservative.

Before it does get killed ;) I disagree with the above largely because I had a 8gb micro sd card and was very excited about the 32 one coming out.

Thats totally fine, cant argue with that. Maybe "You need to be really conservative" - "We" do not. I have more than enough space on my Diamond for my needs. I thought perhaps you were getting confused about how the memory is set up and how filling the \Internal Storage will not effect its speed.

Try an AZTOR rom. Fast, No added extras and reportably no Mp3 lag so would be good choce for Music. New version due any day reportedly.

[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] ArghMonkey:
I have finally unlocked the bootloader (no guides mention it will wipe my phone at the same time!).

Now I am looking again at Roms, HentaiOS and ArrowOS were contenders but Xiaomi.EU sounds like the best of all factors, a Poco F3 centric, manufacturer update with added functionality and removed bloat.

I have watched several "guides" to install, including this one (

) and this one (

) both seem to assume that I am not retarded!

I would like a really easy, step-by-step guide to how to install this Rom.

Do I need to install ADB? Some people say to load the Xiaomi.EU rom in internal storage but to wipe the phone first, so how would I do that? Some say I should BOOT TWRP, others say I need to install it? huh?

There has to be a "explain it to me like im three years old", guide to this!? ACK!
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] cyanGalaxy:
You don't "install" ADB and Fastboot. Those are protocols through which a PC can talk to an Android device for debugging purpose and other purposes like this.

The Fastboot Mode on an Android phone lets you deep system stuff, like modifying partitions (flashing, erasing, etc.)

ADB lets you do more high-level stuff, like removing system apps, granting/removing permissions to apps, pulling/pushing files from/onto storage.

To speak to those protocols, you need the portable Command Line Tools for ADB & Fastboot built by Google:

SDK Platform Tools release notes | Android Studio | Android Developers

Android SDK Platform-Tools is a component for the Android SDK.

developer.android.com

First, you unlock the bootloader (which factory-resets your phone, lol),

then you put the ROM zip-file (e.g. Xiaomi.eu Custom ROM) onto the phone storage,

then you reboot your phone into Fastboot Mode (POWER + Volume Down),

then, in Fastboot, you boot TWRP (a Custom Recovery):

Open Command Prompt inside the Platform-Tools folder,

do "fastboot boot TWRP.img" (assuming the TWRP file name is "TWRP.img")

then you flash the ROM inside TWRP,

then you format data & clear Dalvik Cache,

that's it. I hope I haven't forgotten anything.

I'd also like to include some Notes that I have made for myself in a text file:
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] RollDload:
Good job!

You could almost give us a guide on the dedicated "how to" section 😅

However I read that to start twrp from fastboot using cmd you need to put the twrp(filename).img on the platform tool folder. Right?
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] cyanGalaxy:
Oh yes, that command also assumes TWRP.img is inside the same folder.

What I do is drag 'n drop the TWRP file into the CMD-window. The full path to the TWRP-file will automatically be written in the CMD-window.
