UMI C1 - GPS not working in ported ROM - Android Q&A, Help & Troubleshooting

Hi everyone,
few days ago i've started reading about porting ROMs to different devices because i have free time and i'm interested in such stuff. I've successfully ported a CM12 based ROM (resurrection remix, lollipop 5.1.1.) to my MT6582 UMI C1. But the problem that i'm facing is that the GPS isn't functional. It works fine if i use WIFI assisted GPS (battery saving or high accuracy option) but when i use the device's GPS (device only option) it just won't get a fix. I've used GPS test app to check what's happening, and all 'i see' is 9-13 satellites but none is actually being locked onto. Also CM12 doesn't have com.mediatek.lbs.em (location based services) or YGPS.apk. I've tried 4-5 custom ROMs and none of them had those apps. Kitkat did have those and i was able to check the SNR of the GPS reception per satellite.
In previous ROM (kitkat 4.4.2) GPS worked very good, especially when i've installed modified gps.conf into /system/etc
I was able to get a lock within seconds.
SO...
I've ported zImage (a.k.a. kernel?) from stock boot.img to port boot.img, compiled it and done few other file replacements in port ROM to make my ROM working.
I am not a programmer or a coder. All I do is read/copy/paste/ and enjoy what I've done. I don't sell the stuff I do. It's all just for me. But I can (and know how to) use notepad++ to replace lines in ROM's files so if you know a solution please share it with me :fingers-crossed:
So far all stock ROMs for my phone (UMI C1) are missing all files in /system/lib/modules and i've read that i should replace mtk_stp_gps.ko from PORT with one that is located in STOCK. So there has to be another fix, my phone worked fine without it.
Thanks in advance and i hope we'll find a solution.

Got the same problem porting MIUI 7 / 8 to mtk 6582. Have you found a solution?

Hi,
Nice work. Do you have a git hub source?..
Hi goodoane, i dont have a github account, i have is a local device tree made after asturel device, with many changes in order to compile for my 105.
I found in a russian forum sameone is postinfgversions of pa for 105, i dont speek russian, i love to take a look at there device files to compare to many and see what i'm doing wrong or see what is missing.
Do you have a device tree for the s7 ? we can compare files and see if we can make a more stable version, working alone is hard and progress is slow.
I'm making changes in my files to see if i get wifi working, until now no sucess.
Any help is welcome.

Everything else is working ok
Any idea?

(CM 12.1 last snapshot on I9100) GPS not working at all, already lost hope

Guys, to keep it short - I can't get my GPS working. I have installed CM 12.1 on my S2 and it can't get any sattelite fix. I tried numberous fixes (including changing files like gps.conf or tightenind phone screws), none of these helped. All was working correctly when I had stock ROM and now while using CyanogenMod (from official CM site) I simply can't use GPS except for aGPS.
I tried to find solution both here and via google and found nothing, so asking here seems to be my last shot. Thanks in advance.

ZTE Z7 Max (NX505J) - IR Not Working

I'm deeply puzzled, and a bit annoyed my shiny new Z7 Max doesn't seem to have working infrared. I can see the thing, but software can't.
Bought the phone off Feebay, has a "Westone" logo on the back, along with China Mobile. ROM seems stock, shows as Android 5.1.1 and has no obvious bloatware.
The reception seems no better than on my old THL T6 pro, but the GPS is vastly better (can even get a lock indoors). Both hate having two sims (from the same provider) fitted - Another reason I upgraded, and another irritation, but one I can live with.
There was something about explore Nubia OS when it first started, and I'm used to KitKat, so there might be some tweaks or other away from stock I don't know of.
What's bothering me is I can't find any sign of an IR app on it, and anything I've downloaded just says the phone doesn't have an IR port.
Anyone got any ideas? Or known working/ stable roms where the IR *does* function?
I'm using MoKee, and it seems to work; can control my tv, which is all i've used it for. The app that comes with the ROM is called Infrared control.
This is the one I bought ebay.co.uk/itm/272424574812
I can't find any hint of IR software on the phone as it reached me, so will see if the seller can help (unlikely) and then.. Gasp.. invalidate my warranty by finding a rom that *does* operate the features the phone was sold as having.
I imported mine, but it also came running android 5.1 and with play store. Unfortunately I didn't try out IR before installing custom ROM, and can't remember if there was any IR app installed.
The app which comes with MoKee appears to be a Nubia app though.

I can't find a download for the IR app that came with the phone, so may as well go for a different rom I guess.
Are there any known/ annoying bugs in Mokee?
Nothing I've noticed, but there's some stuff I haven't tested, like second SIM, Bluetooth audio and tap to pay. Probably other stuff too. Do a backup first and you've got nothing much to lose.

I recieved mine yesterday from GearBest. It also has the Westone logo on it and aside from missing the IR app was also missing the FM Radio.
After a little searching around I found a German forum from where I downloaded the, what seem to been stock, apks.
Now my FM Radio is working fine, but IR is still not functioning. An IR Romote App sugested a library is missing....
P.M. If you want the links, since I cannot post them due to new member restrictions.
I wasn't worried about FM radio, but did notice there was no sign of it.
I looked around for the IR app, but kept getting rather suspicious looking, definitely not, IR things in disguise.. Sigh.
It sounds like you've made some inroads though, fingers crossed there's a solution to this (though slapping a non stock rom on isn't a problem, *if* all features work relaibly).
Edit to add:
I've found an official ROM and copied the control and control test apks from it.. But although the app loads/ runs, there's still no sign of life from the IR led itself. No doubt I'm missing something the OS requires, it's been a while since I played with these things (and I wasn't very good at it then!).
I have same problem i extracted from 3.84 romofficial the 2 apk ir control and zfm radio only radio works hope there is a solution out there....
I bought the phone from china bangood and no help is provided...
Infrared works on z7 Max bought from banggood on CM12.1 ROM (www.needrom.com)
But i like the 5.1.1 oficiall rom is there any way to make it work i fixfmradio by finding an zfwapp.apk from previous official rom i also install ircontrol.apk and its the nubia one but is notworking pls help me enable ir here

this is the infrared apk (cn.nubia.control v3.0.1.1011) from the CM12.1 that works 100% in the CM12.1 ROM, you can try it on your ROM and see.
Note: - i beleive it has to be a system app but you can try installing as normal and see if it works, if not then you will have to make it a system app, also the Z7 Max has to be rooted to be able to do as below.
Here's how to make it a system app -
1). Install the attached app as usual.
2). use an explorer app like 'Root Explorer' and
move "ZTE_IRControl.apk" (which will very likely be in /data/app)
to /system/priv-app
then restart phone and then try the infrared app.

I can't install apk ..... Phone is rooted
---------- Post added at 03:53 PM ---------- Previous post was at 03:35 PM ----------
This apk doesn't install I have the phone rooted and my ircontrol.apk that I got from previous ROM I install it doesn't work then move it to system/priv-app reboot still not working I'm loving this phone but I don't like that ir is not working
I got mine from Banggood as well. Here's how I got both FM and IR working. All referenced apps unless otherwise stated can be found on Needrom under the Z7 Max section.
Phone needs to be rooted - use the utility "Z7 Max All In One Tool v3.3.0" to root and install TWRP, followed by SuperSU ZIP file from Chainfire via TWRP.
Extract the nubia_IRControl1.apk and nubia_ZFM.apk from the Stock ROM V3.89. Place them in your SDCard/microSD card.
Under Settings > Security - Allow installation from Unknown Sources, install the IR and FM APKs.
I used 3C Toolbox Pro from Play Store to move both apps to the system folder. Both runs nicely in the stock Nubia 3.96 that came on the phone.
Further on, I flashed the ResurrectionRemix Nougat Rom dated Feb 03, 2017, both IR and FM apps are already included and working. Both the stock and RR ROMs were working nicely, I just wanted the latest security patch by moving to RR.
For starters thank you very much for your help I already root my device with kingroot and I copy the twoapks from previous ROM 3.89 and install them then made them system apps by copying them to priv-app with root explorer
The problem is that the IR still not working can you help me skittle bit more cause I don't won't to change ROM I like this 3.96 please advise...please
finally I flashed the ResurrectionRemix Nougat Rom dated Feb 03, 2017, both IR and FM apps are already included and working...do you have a link of official rom 3.96??
Unfortunately I cannot find a download for 3.96, the latest available is 3.89 from Needrom.
hi
i too have the same issues, basically the IR has not been built into the lollipop rom. any help greatly appreciated as i love this rom
Radio is working on 3.96 but not ir only in RR nougat
Had other things take my attention off this problem - Glad to see lots of useful info in the thread now
I'd better get downloading and faffing.

Can anyone recommend me a stable custom ROM for the 5g version?

Hello everyone, after struggling with basically any custom ROM that I have tried, I'll report the errors here that I've had because I need a ROM that works decently, hopefully.
Paranoid Android (Android 10): frequent random crashes and reboots, audio codecs broken (some audio is really bad).
Lineage OS (Android 10): failures flashing it.
ShapeShift (Android 11): even more frequent crashes and reboots, mobile data not working.
Arrow OS (Android 11): I couldn't even complete the setup because of services crashing during the first configuration after flashing it.
I'd like a debloated ROM, less is more.
Or, if you have a flawless working ROM among the previous ones, please just link me the MIUI (and the firmware, if needed) I have to use to make the exact same installation you have (this is driving me crazy, it's about a week that I'm using a not decent phone). It's the 5g standard, no pro/ultra/lite.
Thank you.
Only stock roms work perfectly. Custom roms will have bugs.

Well, I have tried like 7 stock ROMs recently, almost all of them were as unstable as the custom ones.
Anyway, I've done the cleanest install possible (flash stock - format - flash custom - format) with Arrow OS and apparently like this it's quite stable.
