[URGENT] X1 can't find T-mobile signal

I have used my x1 for four months in America with T-mobile. The phone had no problem until yesterday. However, yesterday, the phone began to lose signal and automatically rebooted several times. Then, finally, from the afternoon, the phone totally lost the signal, and kept looking the signal.
I took out my sim card and plugged into another cell phone and it worked. So, I thought it was the problem of the rom. (I was using Touch-IT 4.5) I downloaded the new version of the rom, Touch-IT 5.6, then flashed it. However, it did not solve the problem. So, I flashed with the original SE rom. However, the phone didn't work either.
I contacted T-mobile, and there was not problem on the signal on my region. I thought it might the problem of data plan since I do not use data plan. So I used Advanced config and killed every option for data plan. However, it still does not work. I tried to do settings manually. changing band, carrier, and every possible options, but it does not work.
Interestingly, the phone worked two times today for a short amount of the time. However, after the reset, it is gone. Other than phone function, I do not see any problem.
Even now the phone keeps searching the signal. What can I do? I read another article that is similar to my case, and they say even after changing the sim card, it does not work.
Anyone has the same issue? What can I do? My phone is dead for two days, and it messes up so many things. Please somebody help me.

Have you tried redoing the connection setup?

try clicking on signal antenna then enter settings click on network and manual select your network, will take a few mins to find networks if it connects manualy just select auto again and hopefully it will fix it., worked with mine.

Thank you guys
Thank you guys. Yes, I have tried both of them, but it still does not work.
In Connection setup, I chose United States and T-mobile, and the screen to choose between T-mobile and At&t. I select T-mobile, and click Register. Then, it goes to the searching mode again, and nothing happens.
I assume that somehow, the phone finds networks, since it does show the options to choose (T-mobile, At&t). But something is not right, and it messes the set up. I do not know why.

[Q] Lost LTE/4G

My very first post but a long time reader!
Somewhere along the way I lost LTE / 4G. It shows only 3G. Since I am almost always on WiFi, I just recently noticed it. I am on NI2 and 12.6 of OtimalROM. I am in a known 4G area as two other phones in my house are showing 4G - one is another S5. I have tried swapping SIM cards and it made no difference.
Under About / Status - it shows the following:
- Network: Verizon Wireless
- Mobile Network Type: eHRPD
- Service State: In Service
- Roaming: Not Roaming
- Mobile Network State: Connected
- MIN, PRL Version, ERI Version, IMEI, IMEISV, ICCID all have information in it.
When I type *#0011#, I get:
- No Service
- NETWORK: UNBLOCK
- IMEI Certi: PASS, 1
- Unknown
I have tried installing another ROM, ODIN an earlier version of the modem - without luck.
Any suggestions on how to get 4G back?

Not sure if this helps but I tried something I had not tried before. I went into ServiceMode (*#0011#) and then placed the phone in airplane mode and then turned it back on while watching what would happen. This is what I observed...
1. https://www.dropbox.com/s/xnikrs6lmnk1x0d/1.png?dl=0
2. https://www.dropbox.com/s/60c3qv7rtckqdx7/2.png?dl=0
3. https://www.dropbox.com/s/c57ibulvhl64g6l/3.png?dl=0
#1 occurs as soon as I turn off airplane mode
#2 occurs about a second before #3 appears
The other s5 in my home belongs to my spouse and is not rooted so I can't see what her ServiceMode settings are. I can see that her Mobile network type is LTE while mine says eHRPD.
Thanks again for any help.

I also have this problem, nice to see I'm not the only one. I was ready to think it was a hardware issue. I have tried all number of things. Have you at any point been on NK2? I'm on a Dev Edition S5, but stuck without LTE. Hoping someone can come up with a suggestion. My phone status reads the same as yours.

I'm hoping someone will have a fix as well. I have to think it is a setting in a config somewhere that got changed.
I'm on NI2. Have not tried NK2.

I was probing around in my build.prop file. I don't want to change anything in there because I really don't know what I am reading.
Is it possible that there is a setting in there that got changed?
I have looked to see if I can find a "stock" build.prop somewhere but no luck.
Can someone possibly provide me with their build.prop so I can compare my settings?
Thanks everyone.

how does one use that servicemode code? sorry I don't have anything to offer about your problem...
I typed that code into my dialer and nothing happened... actually dialing that number just gives me a message saying Verizon can't connect my call...

Open file /efs/carrier/HiddenMenu and modify its content from OFF to ON. Then reboot the phone.

I am on a Verizon s5 and I also lost LTE/4G. Also I cannot select any APN or mobile network. Any luck on your situation?

Sorry...I have not. I finally did a complete wipe of everything and took the phone back to stock - no safestrap, no root. I still had the problem. i don't know if there is a file on my SD card its pulling from. I have not taken the initiative to reformat my card. It's 128 GB and is half full. I don't want to even tackle that - as I really don't think that is the problem. I also don't think it is hardware though. Don't really know what else to do other than wipe the phone back to stock and replace it with another.

Well guys - I got 4G back!!!
Even though I'm still waiting for OptimalROM r13, I decided to install Extreme Syndicate OA8 in the meantime. I don't know why but it's back!!

I have imei cert pass 1 but still no service what now?

Band change Canada

Hi, i just got the Nexus 6p on friday.
My carrier is Videotron in Canada. When the sales rep activated my phone, a mistake was made in my account and phone logged on to the network but I couldnt make or receive calls and text messages. After hours with tech support the problem hadnt been resolved so i started playing around with the phone and accessed the *#*#4636#*#* menu. I went to band select and 3 options were there. USA BAND, BAND 6 AND BAND 7. I selected USA BAND which still didnt fix the problem. Today the carrier fixed my issue but now I am always on roaming although phone functions properly. I suspect that it is because i played around with the band selection. Any way to restore it to the way it was originally? I tried factory reset, i tried loading the the factory image and still encounter the same issue.

Anyone?

So no experts here would know how to restore my original band?
I tried rel-flashing original factory image, boot, vendor and radio. Still no luck.

Did you try to reflash the Modem.bin?

Your thread is WAY too specific to gather any atention within the forum. Try broadening you question

Well no matter what I do after going to phone util menu (*#*#4636#*#*) and changing my band to USA Band i continue to be roaming. If I go to cellular network menu, I see my carrier there but when selected it tells it cant connect to it. I have a feeling that when i selected the band i screwed something up. The band i should be using here in Canada is BAND 4 but its not a selection i can make as the only ones shown are USA BAND, BAND 6 AND BAND 7. Is there anything i can flash to it to make it go back to full factory? I did flash the latest factory files, would think the modem.bin would also be flashed through that.

Try this man *#*#72786#*#*

That does nothing.

so i just finished downloading the factory image and there no modem.bin file in there. Where would I find that file?

I did the same mistake and now am left with an expensive music player! have tried everything,no dice. Looks like the one solution is to fix it with QPST but there are no guides out there for the 6P yet. Hope this comes to attention of some dev who can help.

got my phone through videotron. they replaced the phone and all is well. but i'd still to know if theres a solution to this.

@bigxie I read this post of yours http://forum.xda-developers.com/showpost.php?p=37647704&postcount=16. I could be wrong but it looks like this could fix the issue we have here in this thread. The only options I see on the 6P when selecting bands are 'USA band','Japan band', 'Band 6'. I live in India. After clicking on USA band I've lost all radio stuff and no amount of flashing the factory images or factory resets have fixed it. Can't figure where the band change data got stored on the phone. Could you please help ?

Hi, sorry, I just saw that mention.
I've submitted this patch to CM a while ago, so it should be included in CM builds for Nexus 6P. If you're bootloader unlocked, you might try flashing CM to access the full band list.
But, it's also possible that this is a device specific issue (changing the band once sets it permanently?) Since on other devices, I remember that a simple restart just reverts the band selection to default.

Actually, I don't even have a Nexus 6P, I just responded because @SurenSeven dug up my old fix for the band selection feature completely crashing on the Nexus 4 when trying to select additional bands.
This fix has been incorporated in CM since version 10.1. Unfortunately, as CM13 is the only version available for Nexus 6P, and it's still being actively developed, it seems the patch hasn't been merged yet.
Furthermore, even when it does get merged, I have no idea if it'll fix your issue or not.
So basically, good luck guys

Any news on this? I was dumb enough to do the same mistake...

I am having a similar issue in that the phone works when I am in the US, but when I go international it does not work at all.

Flash Chroma ROM dial *#*#4636#*#* select the "Automatic" band that should fix you. You can then flash any ROM or go back to stock after that.

signal problem

Hello,
If the problem has mentioned before, please excuse me in advance.
My wife owns a p8 lite(ALE-L21C150B595). I have this problem which i think occured just right after the last OTA system update(B595).
The phone has full signal only when the selected network type is ¨only GSM''. When i choose LTE/WCDMA/GSM or WCDMA/GSM, it losts completely the signal. The signal in my place is excellent, i own a honor 8 and is always on 4G, and also the p8 lite before the problem occured, had 4G also. I tried a factory reset(without erasing the files), but the problem persists. I also tested if the sim card had the problem. I entered my sim card in p8lite and the same signal problem occured.(I could not place p8lite sim in Honor because is takes nano-sim).
As you understand, the ''only GSM'' is not problem in calls and the general phone functions, but when i turn on the data usage, the internet is very very slow(i have not even 3G!!). Any help or suggestions?
Thanks in advance

Hi.
EDIT: Having skipped the obvious the phone is Single-SIM, right? These may have a delay of up to three minutes before connecting to a 3G or 4G network. It's not a feature, it's a bug.
Maybe you just flased a ROM with the wrong channel-set or band mode for the hardware of the phone. The ROMs have a special band mode for the LTE and 3G channels and that is shown in that number behind the C (CUST number), in your case C150.
Is the phone originally a C150? Is the ROM the same C150?
If not, flash the correct ROM for your region.
Another hack may be (not working on all ROMs):
Install "QuickShortcutMaker" https://play.google.com/store/apps/details?id=com.sika524.android.quickshortcut
Root will not be needed.
STOP here and rethink. This app is a mighty thing and you can do a lot of things on your phone that are hidden otherwise. Be careful and responsible, not to mess up everything and avoid being forced to a factory reset. Anyway, if you mess up something with this app, there will nothing be broken forever, just factory reset and all will be fine again, except for SIM card, which might be garbled up and rendered useless if you choose the wrong action. Be careful. You are responsible for whatever you do.
Now if you are acknowledging this and willing to go on, start that app and set search type to "simple".
Leave the search field empty.
Scroll to "settings" (or whatever it is called in your language) with the cogwheel icon.
Open/unfold this with a tap.
Now search for a line that is subtitled (tiny small letters) with "com.android.settings/com.android.settings.BandMode" (maybe the one behind "proxy settings" in the list, but this may vary)
Tap that line. The next page comes up. Change the label name of the shortcut to be made to "Band Mode" and tap "create/add"
Now you have another icon on your app screens. With this, depending on the ROM you flashed, you may now select the band mode maually.
Even if it throws an error, this does not mean it failed. This menu has just not been fully woven into the system. Check if 4G or 3G work now, this will be the only true indicator.
EDIT: And another hack would be:
Use QuickShortcutMaker to make a shortcut to a setting subtitled as "com.android.settings.DualCardSettings". It is in the list under settings, even on single SIM phones. Use this to check if the used SIM slot is correctly defined as the 4G/3G slot and data link, and correct if necessary.
good luck

First of all thanks for your advices.
The phone is single-sim,not rooted.I have not rooted it,or flashed any custom ROM. The only updates out has, are the originals which they came ota.Its a branded phone from the biggest carrier here on Greece(cosmote). I know there is a delay to have 3g or 4g, but this one has not signal (service) at all when i change the option to LTE. i am willing to check the solution you give me, but only when i am out of the obvious and easy possibilities.As for th right band that you mentioned, i think this isn't a possibility, because it used to work properly all the previous time, and the problem occurred 3 weeks ago. I told you before that is official and i have not flash or root anything at all.I have the feeling that the problem has to do with the last ofiicial update(if it ia not a problem of the sim itself)
Στάλθηκε από το FRD-L09 μου χρησιμοποιώντας Tapatalk

Well, then try to get the most recent update.
Or try the hacks with QuickShortcutMaker app.
When using this, just do not select anything that has to do with SIM, and you are on the safe side. Better than nothing.
Maybe the carrier disabled the SIM 3G and 4G features. Ask them.
It is very hard to help over a long distance. Sorry.

Moto G7 Has No Signal Before And After Fastboot

Hi all,
Greetings I'm new here. Just found this XDA forum last night. What happened was:
a. I have a G7 XT1955-4 and it suddenly has no signal. The sim can be detected, though. It's showing StarHub (I'm in Singapore) and my number.
b. IMEI looks fine, too, but noticed that it's showing Radio Off. Can't be turned on even though using *#*#426#*#*.
c. I read this forum and after many tries, I managed to fastboot using https://mirrors.lolinet.com/firmware/moto/ocean/official/RETAPAC/ (I chose XT1955-4_OCEAN_RETAPAC_10_QPOS30).
d. Other version such RETAPAC 9 or RETAIL 9 and 10 didn't work.
e. However, after fastbooting using the version on point #c (it can load and I configured it just like a first time setup after factory reset), the problem persists. Still no signal and showing Radio Off. What can be done here?
Note:
I'm no programmer and I just managed to get it work by trial and error.

Is Ocean same as River? Either way there is also a setting unset settings, network @ internet, mobile network, preferred network type, make sure that's right, sometimes rocking the settings will fix it. Except your is showing radio off , is a g7 retail ocean? I have not reinstalled stock in years, so I can't remember, but you know a g7 is "river" though, right?

Sorry, I'm not sure if I understand the question, but I seem to see it somewhere on the phone that it's Retail Ocean. Upon further investigation, I start wondering if it's actually a hardware problem...

Sorry was too early and messed up with auto correct, something I found that helps is, playing with settings, found in, settings, network & internet, mobile network, preferred network type(LTE CDMA and so on), make sure that's right, sometimes rocking the settings will fix it. Also there is an APN setting, make sure your carrier is right. Also there is airplane mode and data mode, make sure airplane mode is off, make sure data is on. On custom Rom the worst case Is like getting g3 instead of 4g or 4g instead of volte, a setting I have seen that will keep a phone from connection properly is APN, make sure. If its not one of the above I have never seen it. Have you tried installing a custom ROM with success? Also Motorola now has program, forgot what its called, it'll reflash a stock phone, haven't used it in a while but it'll probably automatically download the correct firmware, maybe it is called moto helper?, also Sim cards can go bad, my g7 has been threw 2-3 already.
