Network issues

I am not really sure what happened. I have JF1.51 installed on my g1 and haven't had any issues at all with it. Today for some reason my phone stopped recognizing the t-mobile network. I tried multiple sim cards and haven't had any luck. My wife has a completely stock g1 and her phone works fine even with my sim card in it. I have tried going into call settings and it just says network error. I know that the phone is still under warranty, but I can't downgrade back to rc29 because I won't be able to re download the updates since I can't log into my gmail account. Does anyone have any ideas on what I should do? I really can't afford a new phone. I could just install one of the roms that doesn't have any theme modifications, but not sure if they would noticed I have an updated spl and radio and apps2sd. Please give me some ideas. Any help is greatly appreciated.

Unroot before taking in to T-Mobile?

Hi, I have a rooted G1 running a CyanogenMod rom and some theme or other (I think it is AeoroBlack or something like that?) Anyway, I've been having some issues with my phone being able to connect to T-Mobile's network, both the data (both Edge and 3G) and the phone signal. I've done some troubleshooting on my own and with tmob tech support over the phone, and it's at the point that my next step is to do a "sim swap." there is a very good chance, though, that I'm going to have to take it into a T-Mobile store sometime soon, either to get a replacement G1 or a new sim card. My question is, if I shop up with a rooted, modded, and themed G1, are they just going to tell me I'm S.O.L., and I voided the warranty? Even though it is still under HTC's warranty, and I have T-Mobiles equipment protection plan? My question is, if I do bring it in, should I switch it over to T-Mobile's official build before doing so? If so, is there an easy way to get everything back to the way I have it after I'm done with them, or if I get a new phone? Thanks for your help!!!

I would just leave your phone in the car and take in the sd. If the new SD doesnt fix it then I would think about unrooting it.
Have you tried doing a wipe and reinstalling your ROM yet?

When you say sd, you mean sim, right? Also, I haven't tried wiping yet, I was about to upgrade to the newest cm rom anyway, which requires wiping. If I do that, will a nandroid backup save all my stuff, or will that take me back to the old rom? I am still unclear on how nandroid works. If I install nandroid, I have to install adb, a new radio, and fastboot too, right? Thanks again for all the help!

I work for tmobile
I work in a t-mobile store and if u come in with a rooted phone I would high-five you! but u should be fine if it is just a SIM swap. if anyone asks about the theme just say it is Fresh Face or what ever it is call(it is an app in the T-mobile app pack). Now as for getting a new phone you will prob have to send it in, but for a SIM swap they shouldn't give u any trouble after the initial troubleshooting questions. Point is most t-mobile employees wouldn't know a rooted phone if it hit them in the face.

I did a SIM swap without having to remove root, but the reps did tell me they could exchange my phone unless it was running stock ROM. I had to remove root before I could get my phone warrantied.

[Q] [AT&T] Dreaded "No Service" Icon

Update:
I ended up sending it to Samsung and they fixed it for free lol
Model: AT&T SGH-I337
Baseband: I3377UCUAMF3
Firmware: Stock/SHOstock
I bought a used GS4 on Swappa last week. Got it today, rooted w/ Kingo, and installed Safestrap.
I put in my old sim from my GS3 and can't get service on the stock FW or any SS-safe ROM I've flashed.
- All other radios (Bluetooth, WIFI, NFC, etc.) work with no problems.
- The SIM works on my AT&T GS3 with no problems.
Now the strange part is that the SIM is getting recognized, but is missing certain information. (See screenshot)
+ My phone # shows up and is correct
+ My IMEI is correct and matches the sticker on the back
+ Somehow, signal strength is showing up in service mode
I've attached screenshots of various service mode screens that could be of use.
Now the question is: What should I do/ how do I fix this?

Does this happen on both roms?
Honestly, I'd go get a new sim. Cheers

Yes, I've tried it on stock and 3 ROMs I've flashed.
I'll try my brothers ATT SIM when I get home today.
I'm also going to try removing Safe strap and root, then factory resetting.
Sent from my SGH-I747 using xda app-developers app

- UPDATE -
So I successfully removed Safestrap via ADB, removed root, and factory reset from stock recovery.
The no service problem still persists. I guess the only things it could be now are:
+ My SIM is somehow messed up, as xBeerdroiDx suggested.
or
+ The SIM tray needs to be replaced.
The original owner called me today and affirms that the phone completely worked before.
Does anyone know what else internally could be causing this?

- UPDATE 2 -
OK now I'm at a complete loss. I tried other working AT&T SIMs. Nothing.
Tried replacing the SIM/SD card tray. Also nothing.
I've flashed all stock MF3 and reset EVERYTHING.
I've even gone as far as enabling the service menu and doing a NV_REBUILD multiple times.
Only thing I haven't flashed is a new .PIT because of the signature checking issues with MF3.
It's weird, because I can get a signal if there is no SIM inserted. And I was able to enable data and LTE functionality at one point by messing with the service mode settings. But that was it. No calling or cellular functions.
Could it be that my /EFS partition is somehow corrupt?
I'm getting close to giving up and seeing if Geek Squad can send it in with no warranty/coverage. I don't enjoy having a $400 wifi browser.

No SIM card - No service after Android 8.1 - Oreo Update

Hello everyone,
I am new to the forum and I would like to reach out to you guys to see if anybody can help me with an issue I am having with my Essential PH-1 phone after updating it to the latest version of Android. Basically the issue is that the system won't recognize my SIM card after the update, it just says "No SIM card - No service".
I've tried so many things already but haven't had any success, here is a list:
-> Rebooted several times.
-> Cleared cache.
-> Reset network settings.
-> Did a factory reset.
-> Rolled back to Android 7.1 (SIM card works) then updated it back to 8.1 (SIM stops working).
What's really funny though is that my girlfriend has the exact same phone, from the same carrier and she was able to update her phone to Android 8.1 without any problem. I also tested my SIM card on her phone and it works fine too.
Has anyone else experienced this issue? Any ideas on how to troubleshoot it?
Thanks,
Mike.

Where did you get the phones (hers and yours since you specify a diff)?
Did you try the unlock on this thread.
What carrier SIM are you using?

I haven't had that issue on this phone. When I previously encountered it (on the Pixel XL?) I powered my phone down, removed the SIM card, booted the phone up into Android with no SIM, powered back down, inserted the SIM and powered back up.
When you did the factory reset did you restore your phone from a Google Cloud backup? If you did you might have also restored the data that was causing your problem. Choosing the fresh start option instead of restoring from a backup is a much better idea.

Me too, with some added info

Might try having your girlfriend power cycle her phone.
I'm having the exact same issue with phone, Sprint service, except it did not manifest itself until a few days after the update when I power cycled the phone as the youtube app locked everything up.
I tried the advice above by the original poster, and the second poster, less the factory reset, to no avail.
Still looking for a fix. May revert to the prior version if I can figure out how to do that.

I am with a Canadian carrier called TELUS. I assume my phone in unlocked already because before the update I tested it with SIM cards from different carries and they all worked fine.

Yes, I did a fresh install, multiple times actually and it still didn't change anything.

Have you tried manually installing one the current builds from the manufacturer's website? That is what I plan to do next but haven't had the time yet...

I just did a SETTINGS/SYSTEM/RESET-OPTIONS/RESET-WIFI-MOBILE-BLUETOOTH.
It was fast, then I restarted. That worked for me!

This also happened to my wife's phone. It just started not recognizing the SIM card on Thursday the 19th. I tried a soft reset, a hard reset, removing and reinstalling the SIM card, updating the Profile and the PRL, all to no avail. I took it to the Sprint store, and they had no fix for it but gave me a code to dial ( *#*#72786#*#* ) that gives you some service for a short while. I finally had to file an insurance claim on it and had them send me out a new phone. I will not be updating to Oreo until they push out a fix for this...

Hey guys,
Just wanted to give you an update on my issue, not sure which one of these things helped but this is what I ended up doing and it seems to be working fine now:
-> Rolled back to Android 7.1
-> Reset Wi-Fi, mobile & bluetooth settings
-> Reset app preferences
-> Downloaded & install android 8.1 oreo update
-> Took out SIM card and restarted the phone
-> Connected to wi-fi
-> Inserted the SIM card and now it has been working fine

Glad to hear it's now working.

I have the same problem first with [ROM][8.1.0][trlte] Resurrection Remix 6.0.0 [20180425][OFFICIAL]. I took out the SIM card and inserted it back to the older Note II runing RR 5.8.5, it works!
Then I installed lineage-15.1-20180427-UNOFFICIAL-trlte.zip from https://basketbuild.com/devs/ripee/trlte [20180427 today], again, NO SIM CARD!
I noticed that both RR and Lineage Oreo 8.1 have the same problem at the first time system reboot: they both ask for inserting SIM card even though the SIM card was already inserted. I have never had such an issue in the countless ROM changes with earlier versions. Since current RR also use Lineage Oreo 8.1, I think the problem most likely comes from the Lineage Oreo 8.1.

I don't get it. Just realize I may be using a different phone (Galaxy Note 4). This method won't work.

I have a Motorola (Moto G5 Plus) and also had this problem. For me it occurred after 1st power down/up after update to Oreo 8.1 (from 8.0). Note that my phone has a dual sim (which I guess might be important here).
This is what worked for me
Settings → system → reset options → reset wifi, mobile, bluetooth.
Turn off the phone
remove sim
Start the phone.
Settings → network → SIM cards → enable Slot 1.
Then the screen with PIN-unlock was finally shown. I just needed to enter the PIN and it now works.
So thankfully didn't need to reset the system or even application settings. Just needed to enter my WiFi password again after all that.

Essential PH-1 SIM Card Problem
I discovered there is an information tag in the SIM Slot (it's got the texture of a mattress tag) the tag has FCC and Consumer Compliance Information printed on it. In my case, when I slid the SIM card into the SIM slot the tag got between the SIM Circuit and the SIM reader. I blew out the SIM Slot with canned air and the tag extended out the SIM slot. I tugged slightly on the tag. It's firmly attached at the top of the Sim slot. When I slid my SIM card back in I had a connection. I contacted Essential and they confirmed that the tag is there and said the tag shouldn't be a problem, but I think in many cases it might be. Essential said I could remove the tag if it interferes with the SIM connection.

I've been having this problem with the newest Android 10 update after about a hour of installation. I'm running twrp with stock Android tried resetting the connections, restarting the phone, and pulling the Sim tray and reinserting. The only thing the fixes the problem is wiping the phone and reinstalling. I'm currently back to running the last build. Anyone else having this problem?

"No SIM card detected" & "No service"

Hi all,
I have a problem with my XC, i hope there's someone here who could help me out with this .
I get a SIM card error when i start the phone. After a while (5-10 mins) the error transforms into "No Service" as if the phone now detects the SIM card but has no service whatsoever.
Things i did to my phone prior to this:
- unlocked bootloader
- installed custom recovery
- root
- installed custom ROM
- drm fix
The phone did function properly for a few months actually after these operations without a SIM card error even once. But then i tried to install custom ROMs again (and i'm sure didn't flash ROMs not suited for XC) -actually tried to install "existenz" ROM but i did get a bootloop so i -once again- did the usual procedure with flashtool and flashed a firmware to set everything back to stock as close as possible. That was, when i started to get the SIM card errors. After several restarts (cold and warm) the phone sometimes recognized the SIM card and i could use the phone normally. But this was true only till the next restart, where i got the same SIM errors again.
Things i tried:
- flashed several different firmwares (official) with flashtool (wiping everything) - all the newest firmwares.
- *#*#72786#*#* in dialer to wipe carrier settings
- *#*#4636#*#* in dialer to go into phone settings and changing those settings randomly
- flashed another AOSP based custom ROM instead of stock sony
- wiping and formatting everything between the flashes of course
- cleaning and re-inserting SIM card (which i never took out before anyway)
But unfortunately nothing worked. Phone keeps to not recognizing the SIM card (which is working just fine in another phone). Everything else works just fine on the phone. The IMEI is displaying correct. I'm almost certain that the fault isn't hardware-based (i didn't drop the phone or exposed in water etc.) but software-based. Did i just managed to brick my phone by flashing something related to the modem which i'm not aware of?
I can't find any solutions on google, which help me, which is why i'm posting it here. Sorry for the long post.
Did anyone experience such an error and/or knows what else i could try to fix this? I hope for answers
Thanks in advance!

Anyone?

I've got the same problem.
I didn't unlock the bootloader or anything prior to getting the bug.
I wanted to downgrade to nougat, because aparently it helped someone in the forum below, but I didn't manage to do it.
https:// de.ifixit. com/Antworten/Ansehen/468864/Sim+Card+not+picking+up+mobile+network.+Possible+software+issue+(Oreo)
Did you try nougat, when flashing different firmwares?
Your post makes me question if its worth it, trying to downgrade.

Try to remove sd card if you have one. then restart the phone and see if sim card is recognized.

I had the same problem and I think it was a hardware failure in the end.
I also tried almost all the things you were writing above. In my phone it started slowly. Sometimes the SIM was detected but after some time the connection was lost.
It happened some time after I installed a new battery.
But since there are no original batteries available for the device anymore and the new battery was even worse than the 5 year old original battery, I gave up investigating the SIM issue and don't use the phone any longer.
I bought a new (used) x compact because I still like the size and I saw some development was going on for this device.
In the end I cannot tell whether the SIM was not detected because I broke something while changing the battery or due to age of the phone but I think it was a "normal" failure.
I also read from others that they had the problem and the SIM was working for some time after I switched the battery before it stopped working.
Nevertheless. Good Luck to you. Maybe it is something different on your phone.
