[Q] Anyone succeed with GPS with custom rom

Hi all,
Did anyone able to use gps with custom rom ( I would say CM base). I research and try everything that's I could find here but not success.
Every time I do clean wipe everything including a internal storage. So that will nothing left behind.
I know that stock is work fine with gps. some said that install and replace stock but I have no idea that what file will left in our device when we delete all.

Always had the same problem when running Paranoid Android (not tried other ROMs). Had to return to stock, where GPS runs fine. Would also love to kknow how people have got it functioning.

I am trying too. I modified gps.conf files, tried some workarounds mentioned in cm11 thread like restoring GPS Status backup from stock with titanium so far with no success. Some people say that it works but it doesn't on mine whatever I do.

I run on CM and I don't have any problem. Everything works fine with gps and I didn't use any fix or something similar.
I'm on CM 11-20140627 and I have 1032 phone.

Interesting, why does it work on some while it doesn't on others? Maybe some variants are having problems...
I have xt1033 asia version.

Which recovery did you use?

CWM

As I wonder is about library missing or some partition need from stock ?

I've also been using the micro gapps package, would this matter?

I had problems with Paranoid Android and GPS too... If anyone know something about that, please comment!

I am having he same problem on XT1032 running Carbon ROM. GPS worked fine on stock, no signal with Carbon.
I found many answers saying to flash stock and then reflash custom ROM. I will try it, but I wonder, how does this help? Isn't the phone restoring the whole system? Do I have to keep the gps.conf from stock?

I've read in some CM thread on here you need to flash stock ROM then enable GPS and get a lock. Once you've done that then flash your custom rom. Sounds STUPID and dosent make sense I know, but a lot of people say this is how they got it to work.
EDIT: I can confirm. I've just flashed stock 4.4.4 and played around with google maps. Flashed CM11 nightly and my GPS is now working ok

Did you wipe anything, like Dalvik, Cache and Data, or you just flashed it over?

Sorry people, I was so happy to have my phone back working, I forgot to write it back here.
Yes it worked indeed, all I did was flashing back the stock, going outside to have a gps lock with gmaps, then re-flashing back the Carbon. I also kept a copy of the gps.conf, but I never needed it, the GPS got a fix quickly. Working fine so far, it only takes some tens of seconds to fix, from time to time.
I can't remember if I also did all the wiping, I think I didn't, but I made so many trials in a couple days, I am not sure.
Thanks a lot guys!

Yes, this worked for me too on PA.
I couldn't even see a single sat (it wasn't just a lock problem). No matter with gps patch, gpx fix app, or gps.conf I used.
What I did?: Back to stock, lock GPS, flash again the custom ROM (but don't wipe /system!).
Good luck on that guys, it should work for you too.

GPS works fine on this unofficial CM11 rom for me. Stable daily driver rom for me, YMMV.
General advice is to:
- make sure you get a GPS lock on stock rom first
- flash CM11 (or other custom rom)
There may not be a file left on the device. it may just be that stock contains the code to initialize the GPS functionality on the SoC or chipset firmware. Whatever, it works...

My One won't reconnect to network after it looses signal

Hi there,
Everything was working just fine, but since I switched to a new carrier I can't get the network back as soon as my OP looses it (subway for example). I have 4G as my favorite internet mode and my APNs are good.
Only a full reboot fixes it, not even a soft one. What can I do?
I use the lastest CM 12.1 S rom (YOG4PAS3JL)
Maybe I should try to flash Oxygen's modem? http://forum.xda-developers.com/one...dio-updated-modem-radio-files-oxygen-t3072516
It seems many users are affected by the problem but I didn't find a real solution, hence my post.
Thank you!

After a long investigation, it seems that the OPO is having trouble switching for and from 4G. I solved it using 3G as my preferred network, but I'd have loved using 4G

reinstall the system... u can google fastboot images for opo... flash them through CMD

I've tried 3 ROMS and at least 4 modems so I think I've tried eveything that's available atm

I have had the same problem for some time now. But no reliable solutions found. Have tried various versions of ROM and Radio. Currently using 44S and CM 12.1 S (YOG4PAS3JL).

Didn't fix the problem. Finally reverted back to Oxygen OS. Complete reinstall, including bootloader, storage, everything. Got it done at OPO service centre. Much better reception now.

Strange Baseband; Strange problems

Hello everyone, this is my first post, after having read a lot in this forum already.
tl;dr: I flashed several ROMs onto the phone and always had the same problem: Connection to network goes away completely when mobile data is turned on. My baseband is S7652XXMA1 for which I cannot find a stock rom. Don't know what to do now.
Comprehensive description:
So I got a Samsung Galaxy S Duos (GT-S7652) and thought I flash some fancy ROM on it to gather some experience before I go and try with my main phone. So I installed TWRP, which went fine, then I flashed PMP Light ROM, because I read that would improve the performance and I liked the ROM.
The problem is, that as soon as I turn on the mobile data, the phone loses network. I double checked APN settings and tried the same SIM card with my other phone and those settings and everything works fine.
I tried to flash back Stock ROMs, but the problem stays the same.
Now I see two potential sources:
1. Baseband of my phone is S7652XXMA1 and I cannot find the right stock rom for this (although I tried some other Stock ROMs, because I thought they would change the baseband, which they did not)
2. When flashing process reaches the fat.bin (which I read contains the baseband) it gives me an error:
Code:
99%
100%
ERROR: Failed to confirm end of file transfer sequence!
ERROR: FAT upload failed!
Does anyone know how to proceed? Does anyone know where to get a Stock ROM for this Baseband S7562XXMA1? All help is much appreciated

Ok, telephony also doesn't work, if one tries it loses network just as in the mobile data case.
Has no one any ideas, how I could overwrite the Baseband?

Try cm11 with Hungarian baseband.
Is network working on phone properly?
You can also try to flash indian baseband, but keep a backup of old baseband

Wifi works without problems, for mobile network see my posts above.
I have not kept a backup, as I thought just reinstalling stock rom would bring me back to original.
Why do you recommend to flash Hungarian Baseband cm11, so far no baseband rom could overwrite my fat.bin, what does this do differently?

So far I was mostly trying various Stock ROMs and PMP Light Rom. Ok, I will try the Hungarian Baseband cm, if that promises better results. I will report back if that worked.

CM11 gives good performance than stock rom for sure.

Hey, I managed to override the baseband with the Hungarian one through the zip from here: [CM11][GT-S7562] Samsung Galaxy S Duos Kitkat 4.4.4
The problems are still the same. I tried to install the cm11 from the same thread (through TWRP), but I get an error (Updater process ended with ERROR: 7) telling me that I am trying to install on top of incompatible data. I tried doing a factory reset, but to no avail.
Right now I am on |DisContinued| COSMIC ROM | Version 2.5 |KitKat-Mod|Galaxy S Dous|Smooth|Fast|Stylish, which also is based on cm11.
I will try to flash some other ROM from PC, but I don't have much hope that will solve anything. Does anyone know where I could obtain a Stock ROM, that is compatible with Hungarian Baseband? There is a link in the Kitkat Thread above (http://d-h.st/do72), but it only gives me some exe-file instead of the tar.gz that I look for...

I don't think cosmic is based on cm11 its just kitkat themed stock.
Try to again download cm11, u will find a new experimental build on last pages.
U can find the stock firmware from this thread.

Its hosted at http://d-h.st... The only thing I can manage to get from there is a 7z1602.exe, which seems like a bad idea to execute. Can you download from there? If yes, maybe you could then upload it to a different file hoster, I would be very grateful.

Yes i tried to download stock Hungarian firmware from cm11 thread, it isn't working.
i reported it their.
Have you tried to download from here, download your country firmware - https://www.sammobile.com/firmwares/database/GT-S7562/
You will have to flash with odin , their are many good guides available for that on Google

They provide flash file which can be used with odin through computer. It will install stock samsung firmware of your country, so it will make the whole phone new, don't forget to backup your data.

I started this Thread because that messed up my mobile network connection, so it is not "new". I need some firmware, that will work with my (now) Hungarian Baseband.

You say that you cant flash basebands through recovery, so now the best option is odin only, now i am out of ideas about for your problem

I was able to flash the hungarian baseband only, no other worked. Now I do need some ROM that works with that Baseband. I posted a request for a new link in the Thread, maybe I then can proceed and make some progress.

Just if anyone is still following this, I have managed to restore the network connection by using the Hungarian Stock ROM, which I finally managed to locate. If anyone needs it too, here is a link:

Modem question

I have problem with my 3G and 3g+ and data signal. Sometimes even if phone shows that I got signal I cant use internet, call and recieve call.
I get an sms that people have tried to call me.
I have tried alot of different modems but get the same result on all of them.
I have tried alot of different 7.1 roms but get the same error on all roms.
Anyone know any modem that really works with 7.1 roms? Right now I have install the Tugapower rom which is based on Lineage OS.

The carrier was working fine on your device before flashing TugaPower?

Not sure, have tried a few roms, might also been after installing Cyanogen or Lineage.

Might want to check your APN settings too

I tried a lot of ROMs and I'm having this problem since COS13. I just live with it and reboot when this happens.

[q] need help with no service and no mobile network available

I have no service and no cellular network problem on my N5, running dark rom 7.1.2 aosp, with franco kernel ( never had issues before ), newest radio and bootloader. This started happening when i got my new sim card from my provider and i got 4g signal in my area for the first time. I tried manually selecting radio by going in the hidden menu by entering *#*#4636#*#* and i got lte and full bars signal after selecting band 8 ( 1800 hz ) but only for a minute then it went back to empty triangle. Tried selecting 3g only in preffered network, tried manually selecting provider, tried toggling airplane mode on/off a bunch of times nothing works. Any suggestion would be highly appreciated, i love my N5 very much and i would hate to throw it in a drawer somewhere. Thanks in advance

Were you ever able to get this rectified? I have recently been having this problem as well. I have flashed back to ROMs I was previously using and flashed back to stock to no avail. My SIM card works in other devices as well. I really do not want to have to drop on a new phone, but I have tried every solution I have found online to no avail. I think it's fair to say that I am desperate right now.
edit: I found another thread on XDA that I'm looking into, I'll edit again if it works. I'm unsure how it took me so long to find that thread.
edit2: https://forum.xda-developers.com/go...getting-cdma-networks-to-nougat-roms-t3534679 is the thread that I found useful; I am now running Pure Nexus 7.1.2 with a full connection. Specifically, his second comment about installing 6.0.1 stock, backing up the efs, flashing the desired ROM, then restoring the efs is what ended up fixing it for me.

No luck with aosp by santosh m and pure nexus 7.1.2 , can't even get it to connect. I guess my last hope is caf based i will try lineageos caf. All i need is the efs backup from stock? If i can get it to work with 3g i will be satisfied because i did some digging and found out that my network provider which is Vip MK has no lte support for nexus 5 d820 ( my model ) only 3g, but i can't even connect with 3g selected. I guess because this one is for US frequencies it will not work whatever i try but i will give lineageos caf a chance.

I was able to get 3G only to work on my Nexus 5 by reflashing the EFS from 6.0.1; I'm trying right now to see if I can install PureNexus 6.0.1 then dirty flash to PureNexus 7.1.2 with any success. Also, I might just switch to T-Mobile, but I have to wait until later this week for that.

Hi,
LTE band 8 is not in 1800 MHz but first of all you can check your N5 model - US model is D820 and is not supported for LTE on 1800 MHz (band 3). For 1800 Mhz band you need D821 model.

To clarify that:
You had the problem with not recognizing the sim or having no service at all. And you solved this by flashing the sstock 6.0.1 backing up the efs, flashing to Pure Nexus 7.1.2 and restoring the efs immediatley after flashing the rom (+kernel+root+etc)?
This solves this mysterious no sim/no service bug, which many (?) N5 owners experience? If this is true, I'd be really happy

It didn't stick. After I lost it I was unable to get it back. I gave up and switched to T-Mobile, where it is no longer a problem. Apologies for not having more testing information. I was able to get solely 3G on multiple instances, but getting the elusive 4G was beyond me.

I've had this problem before in two nexus, one of them running latest stock and the other a customized ROM. I tried to flash a stock ROM image in both of them with no luck. I was pretty sure that the image I was flashing was the latest, so the radio & bootloader should be flashed to the latest versions. But it didn't worked.
Finally I found on a XDA thread where someone was posting only the latest bootloader & radio to flash. I did it with NRT (in Advanced Utilities) and it worked:

I can't remember or find the thread, so I post the images here:
- Bootloader-hammerhead-hhz20h.img
- Radio-hammerhead-m8974a-2.0.50.2.30.img
I think I had to flash them twice because the first time it wasn't right, but there were 4 months since then and still no failure

Thanks for your input. I'll check that when I have some time. This is really weird as it looks like a hardware problem but if you can fix it with this method it's clearly a software issue...
