Hi,

here you can find my crDroid 8.2 builds for our kona devices,

this is based on:

https://xdaforums.com/t/lineageos-19-0-android-12-for-gt-n5100-gt-n5110-gt-n5120-beta.4366627/

This is a BETA build, also on the crDroid side, so don't install it if you want a completley stable rom and don't report my already listet bugs!

When you have BitGapps installed, you have to reflash them after every update!

Here you can see how far everything is working for now.

I would recommend to use microG (much faster experience) or open Gapps as soon they are available.

Do you like my work?

Than you can simply hit the thanks button and consider to spend me a coffee or a beer,

I'm doing this in my free time and it also costs a lot of money to buy hardware.

[Galaxy Note 8.0 (Tablet) Android Development] html6405:
N5100 and N5110 will follow soon, I have to make the system smaller for them.
[Galaxy Note 8.0 (Tablet) Android Development] html6405:
N5110 and n5100 builds are up :).
[Galaxy Note 8.0 (Tablet) Android Development] TibReg:
Thanks, installed it and it is running smooth from the beginning. Not sure besides the nice UI tweaks, if there is for me a big benefit compared to regular lineageOS. Are you planning to get one of the ROMs for the GT-N5100 into the mainline of LineageOS or CRDroid? It is great to have so many options for this trustworthy device but one point in time I probably will settle on one development line. Thanks again
[Galaxy Note 8.0 (Tablet) Android Development] html6405:
Hi,

I can't make them official because of missing ebpf and many other needed hacks.
[Galaxy Note 8.0 (Tablet) Android Development] TibReg:
Thanks, I was not aware of this pre-requisite. So we can even be more happy about such a well working ROM 😍
[Galaxy Note 8.0 (Tablet) Android Development] xxmanowarxx:
Thank you for this ROM :) only one question before d/l it, BT Headset while voice call is working ?
[Galaxy Note 8.0 (Tablet) Android Development] nCoV:
For some reason none of your A12 based ROMs work for me, tablet (N5110) is always stuck on bootlogo. LineageOS 16/18.1 work fine. Any ideas? Maybe some logs from recovery would help?
[Galaxy Note 8.0 (Tablet) Android Development] html6405:
Did you try the most recent LineageOS 19.1 ROM?

Also a new version for crDroid is in the progress.
[Galaxy Note 8.0 (Tablet) Android Development] nCoV:
Yes, and recent version of crDroid as well. Will try once more, just flashed RRR 5.8.5 to check if my device is okay and it is.

[Galaxy Note 8.0 (Tablet) Android Development] nCoV:
Excuse me, didn't notice the NEWEST build available. It works fine. But for some reason N5110 build asks for SIM-card on initial setup, is it okay? Sorry if it has been answered before I am a little bit stupid.
[Galaxy Note 8.0 (Tablet) Android Development] html6405:
Yes, just skip this part for now, it won't be shown in future.

[Galaxy Note 8.0 (Tablet) Android Development] mymyway:
Are we coming out from beta yet? Or the question should be what are the differents between beta and final version?

Currently I'm using your lineage 16 final. Great works. Really appreciate it. Thank you

Not yet, final means that I will not work on this version, it reached it's final state from my side.

Hello! My device is 5100. Does anybody encounter a problem, when applications do not want to start, device just comes back to home screen. But after some time (many minutes or even hours) it may work normally.

The same situation was on Lineage 16.

Another problem - how to get write access to external SD?

Hi, Root Using Magisk version 22.1 and install ExSDCard Access Enabler Module using it.
[Galaxy Note 8.0 (Tablet) Android Development] zeljukan:
Hi! Thanks for reply, you mean this module works exactly with Magisk 22.1? Cause I tried this module on my Magisk 23 now installed and it does not work.
[Galaxy Note 8.0 (Tablet) Android Development] dovshan:
Yes,I think Magisk 23 is not compatible with n5100

I installed 22.1 and it worked! But in version 23 I can't install any module.
[Galaxy Note 8.0 (Tablet) Android Development] zeljukan:
Thanks for information!
[Galaxy Note 8.0 (Tablet) Android Development] html6405:
Just to clarify, Magisk v23.0 is fully compatible, also v24.1, only higher versions won't work yet.

If you're having problems with v23, do a clean installation and it should be solved.

I am currently on the nusantara project android 11 custom rom on my zenfone max m2 and i want to revert back to stock rom for personal reasons.

Is there a flashable stock rom by any chance? I've searched everywhere on how to revert back from custom rom to stock rom with this device and found no leads up until now. Well, one that doesn't involve a pc that is.

I am no professional in flashing, but i can follow the instructions. My greatest thanks for anyone who could help me. Maraming salamat.

I tried flashing the latest twrp instead and it worked! (still no treble thingy option but it flashed the rom this time). Though i also think that if i flashed the pitch black recovery, it would've worked as well. So thank you very much still! 😊

Also, my greatest regards to @Saif Stark for the rom, instructions, and the dm verity file.

I have achieved my goal because of you two. Thank you very much. 😊

Trying to unlock the Bootloader on my X3 pro. Followed everything step-by-step, but when I open the MI Unlock tool (6.5.224.4) and then try to sign in to my MI account I get asked to verify my account using a SMS text verifications code.

I get sent to the Account Authentication page which you can input the verification code but after a second a 'Checking for security issues..." prompt appears. I never receive the SMS verification code, and the "Checking for security issues..." prompt never goes away.

I am running windows, I did run the app using admin settings, and the device is being properly recognized by the Device Manager. I am not running any sort of VPN. I also tried MI Unlock tool 5.x.

I'm completely stumped. Any help would be appreciated.

[Redmi Note 8 Questions & Answers] admyrt:
I'm not asking it necessarily for the Redmi Note 8 but is there any comparison that tests and compares the ROMs in certain aspects?

I've tried 2-3 ROMs that were mentioned as best ROMs for RMN8 and I always returned to MIUI but I'm sick of it because of occasional freezes (could be a hardware problem or maybe because of some tweaks I made to 'debloat') and more importantly bad memory management and annoying battery optimization features.

I'm looking for better ROMs but couldn't find any extensive comparisons, just some guys sharing their experiences here and there.

[Samsung Galaxy S22 Ultra] 5S5dFeC:
Hello everyone, so I got the Korean version of S22 Ultra, and I cannot enable 5G here in the UK, but the N78 band is supported by the Korean version S22 Ultra, and all the carriers in the UK are using N78 (I have tried both O2 and Three, and I cannot enable 5G on either of them).

I then saw this post [Philippines]SM-N9860 TGY/BRI/CHC Snapdragon Users|5G Reception Fix, and I've tried to enter the secret code *#0808#, but the phone does not react to it, so I guess something strange is going on. Also, I've tried this method, which is not working, too.

Oh, and I just want to mention that the S21 Ultra I brought in China can enable 5G on Three's network, but not on O2. This is just confusing. Could anyone help me to enable 5G on this model? Thanks.
[Samsung Galaxy S22 Ultra] daLareid:
Have you tried on of those Android apps that check your network speed connection? it might just be that you're getting 5G speed but the icon is not showing due to your CSC.
[Samsung Galaxy S22 Ultra] 5S5dFeC:
Hi, thanks for the reply. No, I don't think so, because the download speed is significantly lower (500m vs 10-50m), as well as the latency. Also, "SIM card status" in the setting showed that the "Mobile data network type" is "LTE" instead of "NR NSA" (or SA, but there's no SA in UK as far as I know).
[Samsung Galaxy S22 Ultra] 5S5dFeC:
And even 4G (LTE) signal is weaker on the newer S22 Ultra model, does this have something to do with the frequency band as well?
[Samsung Galaxy S22 Ultra] daLareid:
Did you try that method listed in the guide with the Google phone dialer?

Also this might seem dumb but in Mobile Networks, is Network mode set to 5g?
[Samsung Galaxy S22 Ultra] 5S5dFeC:
Yes, I've tried both methods for One UI 3.0 and 4.0, and the secret code is just not working. I suspect that Samsung either changed the code or prevented it from running on the Korean model (since I saw one website claimed that those secret codes do work on S22 Ultra). And yes, 5G is enabled in the "Network mode" setting.
[Samsung Galaxy S22 Ultra] daLareid:
Only thing left I think of suggesting is maybe flashing a different CSC (a compatible one) to see if it works.

OTA and Non-OTA Firmware for S22 Ultra SM-S908U and S22 Ultra SM-S908U1 Versions

See Post #2 and #3 for the Links to the Firmware All of the firmware posted here can be flashed on any U or U1 Device. Each of the firmware's are NOT carrier dependent and only has carrier labels listed in order to have an idea if you might get...

[Samsung Galaxy S22 Ultra] 5S5dFeC:
Thanks, I will look it up, but I hope/think there will be an easier method out there that are less risky than flashing CSC. Have a great day!
[Samsung Galaxy S22 Ultra] daLareid:
Yeah sorry it's not working out so far. But imo your best bet will be to back up your phone and change csc, though you can change CSC without losing data by not flashing the Home_CSC file I think. Great day! hope you fix it.
[Samsung Galaxy S22 Ultra] Ty5982:
I'm in UK and after years away from xda,I've come here as a last resort,my 5g doesn't work also,when selecting network to 5g/4g,I get no signal,1 bar if I'm lucky,calls don't come through,then WiFi calling kicks in,so at the min,my temporary solution is the network is set to 3g/2g,I tried your mentioned code,screenshot shows what I get
[Samsung Galaxy S22 Ultra] 5S5dFeC:
Ok folks, here's what I found yesterday. Using the app called "Cellular-z", it appears that both my Korean version S22U and Chinese version S21U support 5G in the UK, sort of.

But they do not support N78 (or there's no N78 coverage/ the wall is too thick in my home etc), the only 5G NR bands they support is N1 (and N3? Although it feels more like an LTE+ band).

When switching on 5G in the control panel, both phones are using the 5G network, however, only the Chinese version phone shows the 5G icon. The Korean version does not. But the speed is significantly faster on both phone when 5G are enabled. It boosts from 50Mbps to 450-500Mbps in my home (But the latency is similar whether 5G is enabled, maybe because it's not using N78 or the wall is too thick).

I suspect the Korean version S22U only think N78 is the ''true 5G''.
