Recent signal issues - ONE Q&A, Help & Troubleshooting

I recently flashed to Oxygen 2.1.4 and started having issues with signal. I have since flashed several other ROMs and the issue persists. I updated baseband F/W to .4.0.1.c7-00013-M8974AAAAANAZM-1 with still no improvement. I can still get make and receive calls when I'm out and closer to the cell tower but at home, I have a signal strength of about -110 or so which is the same as it was before the update. BEFORE the update I had few signal problems. I'm wondering if maybe Tmobile changed something in regards to their cell tower coincidentally at the same time or if something got messed up in my phone. I don't remember the baseband version i had originally. I need to fix this problem because I have no phone while at home until I fix this =( Please help!

I would try resetting it back to factory cm 13.1.2 by following this guide :https://www.androidsage.com/2016/04/08/restore-oneplus-one-stock-cyanogen-os-firmware/ but download the cm 13.1.2 using this site : https://androidfilehost.com/?w=files&flid=20027

That fixed it, you think it's the baseband or perhaps something else?

Using Sultan 14.1 since it's quite stable. I only tried Oxygen to check if I could get wifi calling but it seems a lost cause on the OPO.

Suddenly extremely poor reception

I'm having major issues with reception in my house, and only on my 16 GB OnePlus One. When switching to my Windows Lumia 635 or my HTC One X+, I get fine reception-- but as soon as my SIM's in my OnePlus One, I start receiving texts extremely late, which is a problem with apps like WhatsApp which require text verification.
I'm running stock ROM. That's CM 12.0-YNG1TAS17L. Stock kernel, unrooted even (ever since I flashed it back to stock to try and fix the reception issues). I've also tried OxygenOS, BlissPop, and Exodus and none of those have fixed my reception woes. Thanks in advance!

You ever get this fixed? I recently took a trip to San Diego and noticed the poor reception there.. a friend of mine, who's also on T-Mobile, has excellent reception with his new HTC One. I, on the other hand, had horrible reception; sometimes none at all. I've manually flashed the latest radio and still no dice.

Yeah-- here's what I did:
1. Flash stock ROM.
2. Update to latest stock ROM version via the CM updater.
3. Install TWRP again if needed.
4. Followed steps here: http://forum.xda-developers.com/oneplus-one/help/fix-cm12-calls-sms-mms-deep-sleep-t3103193
I flashed both the modem and proximity packages after updating to latest stock, and I reflash every time there's a new stock update. Hopefully this works for you!

Wait, isn't the stock from still on 4.4 or something? How does that fix 5.0+ issues? Anyways, I'll give it a try, can't hurt, right? Thanks, I'll let you know how it goes.

Well, stock is 4.4, but when you use the stock CM updater you'll be brought to CM12, 5.0.2. You don't have to stay on 4.4

(Though presumably you could just try flashing modem and prox packages without flashing back to stock-- I just wanted to be sure as possible that nothing would interfere with the packages.)

Flashed an old backup of stock, baseband stayed the same. Also, when I check for ROM updates, it says there are none. Currently on 4.4.4

That's really odd. You're on XNPH05Q? Or another one?
I used http://www.droidviews.com/restore-oneplus-one-stock/ to restore to stock instead of using a backup.

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.

updated: [solved] CM13 No signal (cell or data) after flash, backup wont restore.

I had a nightly of CM13 working, but the SD card wasn't working correctly, so flashed the 20160820 snapshot, and everything was good except there was no connection to the sprint network. Wifi was OK. I tried flashing the latest nightly (20160930), and same issue. All downloaded from the CyanogenMod website.
So gave up and tried restoring the backup but it has failed, sdcard issue.
Tried the snapshot of 12.1 but it just bootlooped.
Edit:
So I tried flashing the 12.1 snapshot (20161001), still the same.
Edit:
I flashed this stock rooted - http://forum.xda-developers.com/spr...ment/rom-g900ppca-6-0-1-stock-rooted-t3387717 and got cell signal, but data only for a few minutes.
Any way i can get cell and data?

Thanks for the reply. I ended up reflashing the stock Deodexed rooted ROM and the cell signal came back, so at least I was able to make calls.
I was about to try an old Lollipop ROM, but saw the latest comments on this Resurrection Remix thread all seemed happy, with no issues, so late last night flashed it. So far this morning I haven't seen any problems, I have cell signal, LTE and the SD card seems to be working as intended. Wifi is good too. Just need to checkout Bluetooth and even that's not essential. Will play with it today and see. So I think I'm good for now. Again, thanks for your reply.

Glad to hear! Don't hesitate to inquire if you have more questions

Unable to receive calls and texts

Hey guys, i needed some help! I have flashed lineage OS several times today. Not just lineage, i flashed aicp rom too, forgetting that its built on lineage. Whenever I flash it, I don't get cellular network. It shows full signal, but once in maybe 2-3hrs I get the signal for 5mins or so max. Does anybody know what the problem is? I asked several guys and also googled it, but the only problems I have seen or heard is having trouble with the phone app crashing and people installing Zip files to rectify that. Any sort of help would be appreciated.
PS: I have checked whether my sim card is sitting perfectly and it is. If I flash cm14, cm14.1 or aicp 12.1 unofficial which was built on cm14, I can receive calls and texts too.
Thanks

Thank you. But the error was in the sim card xd
It would detect mine but I do not know why it never received signal. But it worked for other sims. So theres probably a fault with my sim and I'm getting it exchanged. Thanks!

[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
Flash back to a stock ROM and test it worth your new new.
Does the sim work in another phone?

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.

This morning it's not sticking with Pure Nexus, so I'll be trying DarkRom. I really don't want to use a CAF if I can avoid it, but it may become a necessity. Do people on T-Mobile have this problem?

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...
