Hello! I have a Lenovo s8-50L tablet which has got a SIM card slot. I put a SIM card into it but I can only send text/multimedia messages but can't accept or perform any phone calls. Is it because of lack of some software or is it technically impossible to make a call (I've it rooted, I can install any apps on it)? If I only need some software, could you tell me which apps?
Thanks.
Dont understand your problem!
S8-50L is supposed to voice/sms capable (like HV models for A8-A5500 HV versus A8_A5500H). Maybe you should wait till Q3 this year when that model is due to get Lollipop update - see "Lenovo Upgrade Matrix" attached
[SOLVED] I put my phone in airplane mode and my IMEI/Baseband came back, cheking the service menu I went to *#2263# and saw that "LTE Preference" was enabled. I clicked on Automatic and problem fixed. Probably a ROM bug? Who knows.
Hello there. I've been a reader of the XDA forums for some time but I never had any reason to create an account to post on the forums.
A few weeks ago I got a SGH-M919 as a gift, the phone only had a few months of use and I took it with me, everything worked fine except for the fact that I couldn't get 3G/4G (Not even EDGE), I was only able to connect to the GPRS network and I couldn't change the carrier (It always gave errors like "Unable to connect. Try later" and such). Although the phone is (apparently) quadband (I don't live in the US), it just didn't work but I lived with it.
Yesterday my phone was low on battery and I turned it off, a few hours later I turned it back on and it couldn't connect to the network, I went to the network options and once I pressed the screen to enter the Mobile Network options, I got an alert saying that I must have a SIM to access those option. At first I thought that the SIM got damaged somehow (This isn't the case since it works perfectly fine in another phone) but after a few minutes looking around, I checked the IMEI and instead of the usual number, I got a null/null message. My first reaction was to google what exactly happened and the answer I received was that the Baseband (Which is also Unknown) and IMEI are stored in a folder called EFS and that it got corrupted. Sweet. I looked for solutions but the main two I got (EFS Pro and ADB nvrestore) require a backup of the EFS (Which I don't have).
The other solution I got was to restore to the stock ROM (M919UVUFNH7) which I'm currently downloading from SamMobile (Sorry if this is considered spam). The phone is not rooted and has the stock ROM, it came with a CWM folder inside the internal memory with an .img file but it doesn't have CWM intalled. I've never upgraded it (Not sure if it came with that firmware from the store if it matters).
I live pretty much in what can be considered a "3rd world country". So I cannot send it to Samsung nor I have access to dollars.
Another question is, the phone was gifted to me already unlocked, I don't know if it came unlocked from the original carrier or if it was unlocked via a code or whatever. If I restore to the stock will it lock my phone to T-Mobile again? Would I be able to use it without a SIM card if it gets locked? It's impossible for me to get a T-Mobile SIM on my hands should I ever need one. In the worst case scenario that my phone gets locked, can I get it unlocked by flashing a custom ROM?
I have so many newbie questions that are already answered in other threads, but since it's a lot of information I want to get it as specific as possible to avoid breaking my phone.
If someone can help me with this issue, I'd really appreciate it.
i having same issue in M919
Do you guys get a message in notification bar about sim car removed or something about a sim card? Also, it doesn't matter if the sim card works in another phone. This device has a little issue with being picky with sim cards. If it's a cut sim card, get an original micro sim card

Hi, thanks for answering. I don't get a message about a removed SIM card. I'm also using an original micro SIM.
I already downloaded the Stock ROM but I haven't flashed it yet.

This is a known bug of the s4. It is a hardware problem and I have yet to find a solution. If you google it you will find many threads on different forums addressing this issue. Again, no known solution
Any answer/idea about my issue? . Sometimes I can access Mobile Network Options, sometimes I can't. I can't configure the APNs (They delete themselves after I click on save). Phone Serial Number didn't get deleted (Which is stored inside the EFS folder as far as I know). I also can't select a Network Mode. I click on GSM/WCDMA/LTE but it changes automatically to nothing.

That's what I said? One solution is to change sim cards if using a cut sim card to use an original micro sim. It's worked for a friend if someone I know and also for others on XDA. It's not the solution, but works for some

I would get a new sim anyway if I could. Flashing stock firmware wouldn't hurt as well

Before trying to flash it, is there any risk of getting simlocked again? I wouldn't want to get my IMEI fixed just to realize that my phone is locked to TMB again
UPDATE 1: My IMEI and Baseband randomly got back (My IMEISV was still missing) but after I restarted, they got deleted again.
UPDATE 2: Rooted, went to EFS, didn't find nv_data.
I bougth a second hand s6 edge t-mobile version 64 gb. No issues with the smartphone until i checked for an update.It said the devise have been modified and connect......
I searched and searched about this and when i went to system status,it said custom. I thougth the devise migth have a custom rom but for no reason i openned the unlock device app for t-mobile and it showed my devise was locked yet i had no carrier problems. It even said permenant or temporary unlock . Both of them failed.
Im thinking of taking this phone back to the seller but i want to be sure if its actually locked or some other issue. I think a custom rom was installed on this devise to unlock it before i purchased it. Any ways to know if phone is locked or not?
I should explain, my LG G4 is a H815P, before the update (when it had lollipop) it didn't have any image from ANY carrier, (I mean the image that is shown when you turn on the phone after the LG's logo), the change happened when I updated the phone from lollipop 5.0 to mm 6.0 and I don't know why!! Can you guys explain me please...
I did the update with my sim card inside the phone via LG BRIDGE...was it the cause of this?, btw, the image of the carrier that is shown right after I turn on the phone is the same of my phone line which is Claro, I find this extremely weird because I DIDN'T BOUGHT THE PHONE "FROM THEM" I bought it from another store that sold it as a free carrier phone...and as I said before, the couple of times I saw it turning on it didn't show the image of this carrier and I've always used the same sim card (before and after the update) I don't even know if this also means that from now on I can only use this phone with this particular carrier...what is going on?
I don't like the image from that carrier showing up, what can I do without voiding my warranty to keep my phone "clean" as before?

It's probably just something LG put in there, not that your phone is locked. I used to be from a network called MEO (Portugal) and didn't have any branding, but recently I switched the card for a Vodafone and suddenly LG started suggesting me to install apps from Vodafone (didn't get the boot animation tho) because Vodafone is partner with LG. It's probably the exact same thing you are facing right now, just something LG put on there that is activated when using a card from that carrier
