NFC not working [PE AOSP] [10.0] [MI 9SE GRUS] - Android Q&A, Help & Troubleshooting

Hello everyone, I have a Xiaomi Mi 9SE which is rooted and safetynet check it's Ok. I did have had installed Havoc OS 3.3 and the NFC didn't worked... I've tried to use apps to make payments with nfc and everytime it crashes... Now I've installed a Pixel Experience 10.0 Rom (unofficial) and I have the same problem.. I've searched on Google and I saw many people with the same problem but didn't got a solution so far. Do any of you have an idea on how to fix it? NFC was working ok with the original rom (now I am not able to installit again, everytime I try to flash and boot I got back to TWRP).
Thanks in advance. :good:

@beastball2
You've overwritten phone's Stock ROM., hence you've no chance to install it anymore, unless you backed it up.
This is the price that people who think they must put up a better (?) ROM than that what gets pre-installed by OEM/Carrier pay.

Problem with google app.

Good Morning.
I came here to ask for help for a problem that has been happening to me since 2 weeks ago.
I have a Cubot S200 mt 6582, and have long been using custom roms.
I now use Lineage 6.0.1 R79, and everything was fine until to update the rom, I installed it again.and now I have a problem here.
I can not access any Google app, or even access the mail, as it gives me: device not certified by google.
I have read out there that google has in the playstore now certified devices but I find it strange that badly install the opengapps zip flle, I can not do anything with google.
and stranger, does not seem like anyone complaining about it?
I forgot, IF INSTALLING the original rom kitkat everything works.
If anyone can help, thank you.
thank you

Please note this ROM is only for the SPH-L520 (Sprint) only!!! Do not try flashing this on any other variant. Search XDA for your device, as there are loads of other ROMS for your INTL version
What works?
Everything (was that too simple?)

Great to see a new builder, good job!
Thanks
Many thanks for this ROM. It installed without the slightest hicckup and is working fine. Been looking and trying to replace the OEM software for quite some time now with no success. This was a breath of fresh air. Great coding. Keep up the fine work. Best Regards. Yachtsman
I got it working figured out there's a tool to do it, ty awesome work btw.
Heres's an updated version of Lineage 14.1 which includes November's Security Patch and an updated CDMA(I hope I spelled that correctly)
Updated by: @arco68 (thank him for keeping the s4 mini sprint variant alive)
ROM: http://www.mediafire.com/file/4pwp2...-20171121_233335-UNOFFICIAL-serranoltespr.zip
Thanks for posting! Got it working on my Sprint S4 mini.
Thanks for posting! Got it working on my Sprint S4 mini, too.
I use the S4 Mini's as media players. Lineage 14.1 has better media options than the original OS. Great player for $30 or even $50. My Rockboxed Sansa Clip is wearing out. Smart Audiobook Player is great for audio books. The really great part of using the S4 Mini is the ability to load new content from my personal cloud.
Thanks for the awesome work Michael! any idea which one of your nougat roms are funtioning the best; this one, aokp, or RR? thanks
Also any plans around here to experiment here with oreo or p? I know as it is, that getting nougat is great for such an old device, but its the last true mini sprint phone out there...
Awesome job Michael!!! I really like the size of this phone, and I am hoping that this ROM keeps my phone running for a while.
However, I found a problem when I flashed the phone: I cannot put an account to the phone. In other words, when I go to settings > accounts> + add account, my choices are Exchange, Personal (Imap) and Personal (Pop3). The choice for adding a google account for the phone to sybchronize itself with the google services: play store, App Data, Docs, Drive, etc is not there. Did I miss a step in the flashing?
I sideloaded google play, but it fails because there isn't an account on the phone. Again, Did I miss a step?
Thank you for your time and shared expertise.

I cycled thru the imaging, flashing, gapps thing, and now the phone has connectivity to the app store.
-- Ill create a new post about this, but when I tried to activate the phone, I needed to update the PRL (Sprint) does anyone know how to do this?
Thx
Flashed the original software into the phone, did all the updates and reflashed lineage, so far so good: Everything works as the OP promised. Great Work!!!
R
I installed the original sprint software, updated everything on the phone. Then rooted, flashed and installed Lineage. It has worked about 95%. The WI-FI connectivity has a problem.
- Sometimes it does not let go of the wifi connection when I leave my house & it drains the battery very fast, shut off WI-FI & the problem is fixed.
- Sometimes it does not connect to the wifi, and cannot find a signal (multiple & strong signals available), reboot device & it connects
Does any one have any idea how to solve the issues with WI-FI?
R
Halp?
Spamming this question here in case anyone else had a similar experience:
https://forum.xda-developers.com/galaxy-s4-mini/help/sph-l520-ting-4g-lte-t3817775
(TL;DR - can't get 4G/LTE on Ting even though everything else works perfectly?)
Curiously, I installed this rom on two sph-l520s successfully. After a month, I put back on one phone the Samsung 4.4.2 os. I did a twrp backup.
Several months later, I tried to restore the lineage backup. On reboot, this phone gets stuck with google framework stopped as well as other similar errors. I tried doing a new install after a wipe and it hangs at the lineage logo forever.
After many attempts and restores did not work, I installed the resurrection rom successfully.
Downloaded over and over and so on.
Now I have lineage 14.1 on one phone and resurrection on the other.
Anyone have a clue why this rom will not work on one sph-l520?
I made a TWRP build for the Sprint variant, and also builds of Lineage 15.1 and 16.0 if that's of interest.

It's an issue with Sprint devices to get data working on Roms past Nougat.
Am itching myself to resurrect my S4Mini Sprint...

TWRP ROM Flash Stuck

I use to use my honor 5x l22 on RR (5.8.5).
Lately after a member in the forum said CM13 has better performance& battery backup, i flashed CM13 expecting lot.
It seems now i want to get back to RR.
But when i wiped and flashed RR, TWRP got stuck on ""PATCHING SYSTEM IMAGE UNCONDITIONALLY"
I restored the backup i earlier had on EMUI (B 320).
Now i tried again the same problem persists.
I searched here as well googled. But i could understand nothing (It was something related storage format issue f2fs or something lke that).
Edit (Update) : I flashed Flyme 6 which works on Android 6. So Marshmallow ROMs work good. Problem is with Nougat ROMs
Can someone kindly help me with this in a nooby way?
I would be grateful.

You may need to update TWRP, I know sometimes you require new version for Nougat on some phones

I had a similar problem so I went ahead and flashed the newer Twrp updating mine from v3.0.00, then my problems started. I ended up reflashing back to it after the update screwed my phone. I run nougat roms on ,3.0.00 no problem guess I will leave well enough alone on my L24.

How to remove root completely from Poco F1 installed with Android 9 based custom roms

Dear All,
I have bought POCO F1 in the first sale and I am very happy with its performance. Once there were Android Pie based custom roms, I have enthusiastically tried some of them. I have to thank all developers here for their relentless efforts in bringing the most updated features to our beloved POCO F1. I just have a small problem, I rely a lot on banking apps and all of them complaint that my device is rooted on Android 9 roms. I know that I can hide root by using Magisk but I dont want to use it. I want to know how to remove the root completely rather than hide it. So, Kindly give me some information as to how Android 9 based rom can be completely unrooted.
Unistall Magisk
I have the same issue......my ROM came prerooted.....is there to remove root completely....
You'll have to try different ROMs until you find one that works for you (i'd Start from Pixel experience)
I never had this problem so i have a feeling that you might have missed a step.
(Did you wipe system,data, davlik before flashing?)
(Did you flash an encryption disabler? because you shouldn't)
Just flash a stock Fastboot package. That's the only true reliable way to "unroot" a device.
If your ROM came pre-rooted, it's either a crap ROM or is still being built in userdebug mode for dev purposes. If it's the latter, unrooting is a bad idea and probably won't solve anything anyway. So either accept it, or use a different ROM.

Miuimi 12 sucks....

Hi guys,
this is my first experience report about my new Poco X3 NFC with Miumi 12 after 14 days in use....
To explain: 2 years ago i got my first xiaomi redmi note 6 pro global. This machine is a fine thing, but i never liked the miui surface. So i decided to unlock and root the phone and use a custom rom. This was the very best decision for me.
So far, so good... At least i bougth my new Poco X3 NFC and i got 14 days ago. I heard a lot of "good" things about the new Miui 12, so that was one reason for me to catch this deal....
After nearby 14 days using this phone with this original surface Miui 12 i can say: it sucks, nothing else but the original apps are running smooth. It is nearly impossible to run an alternative launcher, really nothing runs flawless on this terrible, awful surface! The simplest things like "notification badges" etc. are not present, they still are not in function...
Ok, Miui "spend" a launcher: Poco Launcher. Hmm, nearby, but (for me) lightyears away from any kind of personalization. Change icons? Runs partially... Want to unlink the fu..... ring- and notification sounds? Misrepresented!!! This (for me) confusing settings menu? There is no better thing than a clean android system or custom rom!
The next annoying crap is the annoying advertising - i spend a "little" time to "destroy" this really sucking "feature".....
Oh, before i forgot: i tried to run the launchair launcher, ruthless launcher, nova launcher, microsoft launcher and at least hyperion launcher. With all this launchers it is on my phone totally impossible to run all features - on every other phone with custom rom or original they run like hell!
The one and only way to operate this phone "fine and smoothly" is this: leave it in its original condition! But who wants this? Personalization? Inadequate....
But yes, there are two things they are fine: the energy options and the camera app. But thats it for me.
So, this is my experience after 14 days and the next thing i will do is unlock the bootloader, install a recovery systen (maybe twrp or orange fox) and root the phone with magisk. With this solution i hope to improve some things - i 'll keep testing this
Best wishes and greets
I'm using Nova Launcher on all devices since a couple of years. Mui has the habit of preventing background tasks and autostart(never saw this before) for all apps except Xiaomi and Google ones and probably a few other. Autostart, notifications and widgets i only need for a handful of apps(including the launcher), and none of these worked out of the box.
But all relevant options are bundled in the app's context menu, no scrolling thru huge lists including all the system apps. Simply allow autostart, disable powersaving and give the app more or less all access rights. Running pretty well now. It's only the most bloated phone i ever had, but also the most powerful, so thats not an issue at present.
Hi lecorbusier,
thanks for your answer.
With your sentence >It's only the most bloated phone i ever had, but also the most powerful< your totally right
Yesterday i unlocked my X3, flashed TWRP - and wow: System destroyed....
Turned to fastboot, flashed OrangeFox, puh, it 's not broken....
Flashed Magisk also and today i will see what happen....
​
Lmao, who told you that MIUI is a good thing. It's ok, but compared to custom ROM it sucks.
If you want to try custom ROM, ArrowOS is the best optimized custom ROM + Void custom kernel If you want maximum fluidity/smoothness as it's optimized for minimum latency and jank. Battery life is still good in my usage, maybe 2 hours less maximum, but it's worth it. With stock kernel, SOT is a bit better.
ArrowOS gets improvements every day on ROM side with fixes & improvements + occasionally improvements & fixes to the device side.
I tried 5 other custom ROMs (crDroid, Resurrection Remix, LineageOS 17.1, CorvusOS, NitrogenOS) and that's my experience.
Everything works except fast charging information with Xiaomi charger (all custom ROMs have this issue) & Miracast (which I'm not sure if it works or not since I never used it).
So all in all, just flash custom ROM in this one too!
Devil's advocate here ( ), Xiaomi.eu with updated firmware and Stormbreaker kernel feels smooth as butter here -- but it takes some intensive tweaking.
Hi there, good morning from Germany
A short "update"....
After "repairing" (see 3 posts above) I've done the following:
Installed Lsposed (Magisk), installed CustoMIUIzer and started "playing" with the mass of settings in it....
What should I say: I'm pretty impressed.
Almost everything is going as hoped and does what it should! Till now I got no numbers on my notification badges, but this is a part I can live with.
That doesn't mean that i have changed my opinion about the MIUI-Surface, especially the terribly nested settings.... But with a bit of work you can establish a relatively well-running system that you can personalize according to your wishes.
So for the moment I'm pretty happy, but I'm still testing...
Ah, before i forget to mention: magisk and safetynet was another problem. I have found a module that works (for me), look here
So, thats it for today, many greetings and happy easter
Hello everyone,
here 's another short update for miui....
The good news first: it runs, Ruthless Launcher is working, original camera app is fine, other things: see my post above...
That 's it!
Unlock by (or with) bluetooth??? Fail! It seems that Xiaomi only supports its own devices - what a crap.... I clearly miss this function.
I stick to my opinion: miui sucks....
The only point that keeps me from installing a custom rom is the camera app (at least for the moment)...
My conclusion: to use all possibilities of this device you "must" use a custom rom, otherwise you have to live with the restrictions

My main reason to keep Xiaomi.eu, too. When LOS becomes official, I'll brace myself for intensive testing of camera alternatives...
for me, personally, i dont like miui as well. luckily we have a bunch of custom roms out there and even i found a better rom for my daily use, i still try flashing some rom to experience some other features. tho, at the end of the day, i end up using my rom that i am using daily. if you want the rom with alot of customization, have a good BB, and have miui camera, i suggest to use Ancient OS
Hi all together
@dahrel22: thanks for your tip, it seems like this is what i was looking for...
I think I'll test it out, I can't do more than break it
Have a nice Sunday, many greetings from here...

yes bro you better try it. im currently using the old build which is the miui verdor based. the new build comes with oss vendor but i think im not ready to flash it. i having trouble keeping my phone decrypted from oss vendor based roms. so i'll still be using the old build.
After the updates my Poco x3 NFC restarts in stand-by mode or when I'm using whatsapp, suddenly the screen goes to black..and then back to the homescreen... :/
Does anybody tried a custom rom? I would like to give a try.
Hello to everybody,
here 's my newest experience with "Miui-machine"...
I tried the tip from dahrel22 (see 4 posts above) und flashed Ancient OS 5.3 - I did everything according to the description, but in the end I had an encrypted partition on my phone....
Yesterday I had the great idea to cleam my device up und flash it again...
What can i say: it was a horrible trip
Like before I 've done everything as described - but it ends with a lot of issues like "no root" and "no system" directory, unable to mount system partion and so on and so on... This action cost me a lot of annoyance
(I tried this with two custom roms: Ancient OS 5.4 and Evolution X).
I was then able to revive the device using fastboot and the mi flashtool.
The Mi-Flashtool also ended with an error, but the system works - for whatever reason???
So at the moment I'm "driving" this damn Miui again and I'm really pissed off!
Maybe someone from you has a "smooth" idea to solve my problem??
Many greetings and thanks

im feel so sorry when i read your experience. maybe some confusion because 2 builds at the same version have different vendor based. both of them are comes with 5.3 but one comes with miui, one comes with oss. as i say i really have a hard time to keep my phone decrypted on oss when im using orange fox (now im in twrp but still no planning of flashing oss) if you flashed the old build, i mean the miui vendor based build, i think the outcome will be better.
what version of miui are you into right now?
edit: you know i feel bad for you as you need to do this "mi-flashtool" kind of stuff. next time, if you make mistake flashing something, i suggest just to flash miui rom again (miui eu will do) using recovery (i suggest twrp). i did that before many times and it never fails me.
