Problem after installed the third party ROM(cannot use the mobilenetworkGSM, 2G,3G,4G

Dear all,
it is the first time for me to post something in this forum, I hope you guys forgive my poor english
Anyway, I was rooted and installed the other roms but I found that I cannot use the mobile network anymore (even I checked the APN)
I hope the experts in this forum can give me some ideas to fix this problem
thx very much

Hello,
Did you perform a full wipe (Data/cache/dalvic) before you flashed a custom rom? Which rom did you flash?
Head over to the recovery and wipe the above things I have mentioned and again flash the rom and then the gapps..

Could you please share the link of the rom? From where did you download it??
If you have performed wipes correctly and flashed the rom successfully, I don't see any reason for it not to access connection(2g,3g)... You're using the kernel which came with the rom, right?
Gapps means Google Apps... You need to flash it after the rom flash usually...

I'm having the same problem! I just flashed faux kernel with ParanoidAndroid and I can't get any data connection

Bump, any ideas?

I believe they are correct. I tried the APN settings which looked correct that were already there, and I even tried deleting out all the APNs and recreating T-mo LTE one that I use.
I tried reflashing back to stock and I still cannot connect.
I popped my SIM into my Nexus 4 and it works perfectly, but not when it's in my Nexus 5.

Well I figured out my issue, it's super embarrassing.
I had replaced my battery because it wasn't holding a charge well anymore. Apparently the antenna on the volume button side of the phone wasn't pushed down all the way (i think it got unhooked when prying open the cover).
The reason I thought it was software was because I flashed all this stuff right after I put the cover back on. Lesson learned: change one thing at a time, will make troubleshooting easier if things go south,

Hi guys,
thanks for your replies, I was installed the rom made by Carbon,
https:// carbon-rom.com/downloads/?device=hammerhead
Here is my installing steps:
1. Backup all of my data,
2. Download the .zip file from the link
3. reboot into the recovery mode
4. triple wipes.
5. install the .zip frm SD card
6. reboot
7. checked the mobile network.
8. Failed (the logo of mobile signal is still the same as "Off" in the "Mobile Network", No "H", "2G", "3G" or "LTE" logo):crying:
Please tell me if I did any wrong steps in there

After rom flash, flash the carbon gapps: http://www.androidfilehost.com/?fid=23311191640114013
Double check whether the network/apn settings are entered correctly...
You've followed all the steps correctly m8.. not sure what's causing this problem...
Did you try inserting a different sim? May be it's a sim card problem??

After installing KitKat no mobile data

It all started when I installed Beanstalk 4.4.2 on my S3. LTE/4G started working intermittently. I thought it was the rom so I flashed Gummy's latest 4.4.2 nightly build but am still having problems with my data connection. Data worked intermittently for a while, but now has completely stopped working. I have tried flashing other KitKat AOSP roms, but am not able to get mobile data back. Has anyone else experienced this issue?
Thanks!

can you see your baseband under settings or does it say something like "Unknown" under it? if so then your IMEI has been wiped and you need to restore it.

Ok thats good that you still have your IMEI but that version is very old. I would recomend flashing the MF1 firmware and then flashing the Ml1 modem This will ensure that you have the most up to date modem as possable. You can find the firmware files here: http://forum.xda-developers.com/showthread.php?t=1788313

Thanks for your help!

Cyanogenmod 13 Data Connection Loss

Recently I updated to CM13 (the most recent snapshot) and I find that my data has been acting up. When my phone first boots up it works fine, but if I lose signal my phone will not reconnect to data unless I reboot. I tried toggling airplane mode, but to no avail. APN settings are correct. Is there a new radio I need?

It's the firmware that is causing it, flash this:
CM12.1_05-15-15_modem_firmware.zip

I've had problems ever since the first time I loaded 13. Every time I load a new ROM, I have to flash [Firmware_OxygenOS-2.1.4] to get my connection to work. I've tried the Frankenstein Firmware and every other Firmware I can find. The one listed above is the only one that works for me.

thank you, but it gives me an error:

I also have this problem: sometimes data connection stop working, and I have to reboot the phone.
Moreover, also Wifi seems to work worse: when it fails to connect to my home connection, it stays disconnected from Wifi and I have to manually click to connect to make it try again and then succed.

It's because you're using a non-compatible recovery which doesn't allow the file (The Cyanogen recovery). You need to install a recovery like TWRP to flash the file.
I'm not sure about the WiFi. It might be the stock rom that you're using, but I don't know because I haven't used it since I bought my phone.

I had the same problem trying to go back to a stock rom so i could use Android pay, I'll give this a go as well. I would lose everything that used and kind of data connection (even Bluetooth would corrupt).

No Data Connection

Hi everyone,
Could really use your help. I tried updating my phone to Lineage OS and post update, my phone's data connection stopped working. I've tried flashing different firmwares to see if it fixes the problem and it didn't. I went back to my old backup, and the problem continues. I can't access any data connection (no phone, or text either).
Any idea on what could have caused the problem. My steps were basically:
Backed up old Sultan 12.1 Rom
Installed Lineage using TWRP 2.8.7.0
Installed latest Gapps mini
Installed the bacon_firmware_update_2015_05-15_DI.3.0.c6-00241.zip
And data problems began
Now i've tried redoing the steps with the latest recovery and it doesn't change anything. And as previously mentioned, I'm having data connection problems in my old backup as well

Yup, I reverted back to my old backup and no flashing of firmware, and it's still messed up.
Found out that my IMEI isn't showing up so that could be the problem. Went through "the entire internet" and found some fixes, trying them now to see if I can get something to work.
Edit: I flashed to CM13.1 stock. But my IMEI is still not showing up. No idea what to do next. My phone connects to the network, but doesn't let me do anything considering it can't find an IMEI.

Most probably that is an issue with incorrect firmware.

It's not just your imei,it's your EFS and modem.

Type this command in fastboot.

Sbl1 from stock can fix the imei issue.

Are you talking about flashing stock from the thread you linked above? I'm not on the stock firmware from the fix above, I'm on stoch CM13.1.2.
Should I go back to stock CM11 from the fix above? Or can I just extract the sbl1 file from the package and flash it in fastboot?

Okay, I finally got my IMEI back using this guide: https://forum.xda-developers.com/oneplus-one/general/guide-efs-partitions-how-to-lost-t3307793, and flashing stock oxygen OS through their recovery rather than TWRP.
But now, although it reads my sim, my phone doesn't connect to the internet, and when it does, it doesn't connect to 4g. I still can't use data services despite having the baseband and IMEI fixed. So now what are the next steps? Could my hardware be broken?

I installed lineage, still no data connection. Honestly about to give up on this phone. Is there a good stable rom that I should use?

I've tried Lineage and now Sultans CM13, but still no data man. Just my sim stuff is acting weird, and i know my sim is fine. I'm switching carriers and ordered a new sim. I'm hoping somehow changing carriers helps, otherwise I'm **** out of luck.
Edit: Ok, so on Sultan's CM13 I've finally got the data working, but it only works when its on H+ (4g) otherwise no internet/voice/ text. So is there a fix this?

4G is Lte not H+(3G).
Yeah maybe OPO doesn't support the band your carrier uses for data.

Nope, not the case as I've been using the phone for the last 2 years. I read up that the switch between H+ and 3g happens because the carrier only sends data through H+ not 3g, so it happens to every phone, not just the OPO. But now my problem is, I can't send texts over 3g.
I'm going to wait and see what happens when I get a new carrier's sim.

He already tried using the latest recovery...

Thanks for the help guys, I think in this case it was more of a carrier problem. I learned that Wind has been updating their infrastructure causing some network problems. Couple that with a finnicky OPO and you get headaches.
My new carrier seems to be working better (but I've only had the new sim for an hour). Going to do a full day test and see what happens.
Thanks again.

Oneplus one acting weird

My opo fell in water so its screen was not working. My father gave it to a mobile repair shop who repaired it for 4k. When he checked the phone everything seemed alright.He was able to call me etc etc. Then he couriered me the phone. When I got It... It had cos13 latest version. I checked everything except calling. Then I rooted my phone. Flashed oreo. I inserted my sim. It was able to detect that it was an idea sim and import contacts from it but it showed no service. I thought it was the rom. I flashed Tugapower N49. Same problem. So I thought restoring it to stock might solve the problem. Used oneplus one recovery tool to restore it to 4.4 . Still the same problem. It can detect the sim but can not catch any signal. I check my Imei number. Its still there. But I was not able to run the ping test. Then I thought of using this phone for checking roms only and use my Lumia(I hate Lumia) for calling. Rooted it again. Flashed oreo. Flashed its gapps. It show installation complete but its stuck there...... Waited for half an hour. Forced restart. oreo opened but It was nt factory reset although I had wiped it and it shut down after some time. after that my phone reached the android screen only and cant proceed further. I thought maybe force closing my phone during gapps installation did this. Tried to install tuga power.. error executing update binary. Had one more nougat rom. Installed it. Again it didn't show that starting google screen which u see when ever u open a new phone. Basically It was again not factory reset, Wiped everything except system. still this happened. Returned back to stock using recovery tool. Now I tried to install multirom so that I can install the oreo rom. after rooting multirom wasn't able to download anything. Downloaded it manualy. Flashed multirom twrp using fastboot. opened recovery . Not working. phone rebooting. Flashed the previous recovery which I was using before multirom one, That one is working properly!!! What is wrong with my phone???!!!!!

It must be something with the hardware then.You've to disassemble your device and check if network antenna's broken.Follow the tutorial on YouTube.
