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

To downgrade you need to have recovery older than currently installed on phone. Flash recovery and adb sideload older firmware. If that doesn't help then read further.
Backup your data if possible then full wipe using twrp (not sdcard or ext-sdcard). To flash twrp you need search here how to.Now flash full .178 rom. Hope it helps.
This problem occurred to me several times in two different ways. The first one was on stock rom without root. It was hardware "failure" and I simply removed the SIM1 card put a little pressure on the upper metal that holds the sim from falling and reinserting the sim card. After several tries it fixed this problem.
The second problem was software failure after upgrading roms. This still happens today and many users have similar problem. I am fixing this problem by doing a full backup, then format /system and /data, and installing a clean ROM and at last recovery.
I think the first solution should help you.
cheers!
Hi Guys
So my phone started going all wonkey on me, I tried hard resets ect but some issues happen over and over. I contacted Hisense and asked where i can get the firmware but they showed me the middle finger.
I started googling and downloaded about 6 firmware versions and tried all of them, some only shows 1 sim, others show 2 sim but sim 2 is greyed out and not availible.
I need both sims. 1 is used for calls and other data..
Can anyone please help me get the firmware for Hisense KO C20 dual sim LTE ( 3gb rom and 32gb storage )
I have even tried needroms and not even theirs are right
Im in South-africa, but dont mind other roms aslong as i can enable english and dual sim use.
Thanks
Guys :good:
I have a lg g7 dual sim model Lm-g710emw, when i update to pie by lgup it brick bootloop at bootloader
I repair it but when the phone on it is show lm-g710awm and lost serial number and lost 1 imei
I dont know that, can anyone help me, sorry my bad english
Did you ever find a solution? I have the same problem
For anyone else searching for the same problem, losing second dual sim function and imei when flashing different firmware....I think I have found a solution! It seems to work so far and is really simple.
use the svc menu.
type in keypad:
*#546368#*710#
Choose svc menu
Then mid info
Then go to the field FTMModelName
And enter: DS
Two letters, nothing else. That's it (i'm guessing it stands for dual sim)
Restart phone for good measure. The dual sim function then remained when I reflashed other roms. And my lost imei magically reappeared.
Simples!
I hope this helps someone
I bought a Canadian variant Samsung Galaxy S20 (Snapdragon) yesterday, and knew that the SIM reader slot was faulty and needed to be replaced. I had assumed that I could just use eSIM, but didn't realize that the Canadian variants have it blocked.
Any advice on how to enable it? Can I maybe flash international firmware onto it to have the SIM card manager and enabling of eSIM, and if so, which one and how? Using Odin? Or a modified Odin? Do I need a working SIM reader?
Or maybe I change the CSC? If so, any instructions on how to do it with my variant?
Or do I need to root? If so, any instructions on how to unlock the bootloader (I don't have the OEM unlock option in Developer Options) if I am on One UI version 4.1? Or do I need to downgrade? If so, how do I downgrade?
I really don't want to have to tear this phone apart and resolder on a new SIM reader slot. It's a really great phone and the nicest one I've owned.
I'm not sure where to start.

SM-G981U1 XAA seems to be still on Android 12. I'll wait until 13 is ready before I attempt. What is "nr sa"? Thanks.

I read that if the W model is flashed with the U1 firmware, Samsung Pay can no longer have Canadian credit cards added. Can someone verify? OneUI 5.1 is being tested on the S20. We can only hope Samsung enables eSIM for that release.
W model has 13 release now. Does it still not support esim?
I was on the U1 model Android 12 in Dec 2022 (With esim enabled) and updated to the W model Android 13 firmware figuring it should have esim enabled however it did not.
I used odin to switch to the Android 13 U1 firmware but it did not enable esim (I used the home_csc). I flashed the older U1 Android 12 firmware which did enable esim again but I had to factory reset the phone due to a boot loop.
After reseting and doing an OTA update to Android 13 the esim stayed enabled and I restored a backup using smart switch for my apps and settings.

So in summary, to get eSIM in A13 U1, first odin install A12 U1, and then OTA to A13? The A13 U1 was uploaded yesterday ( link ).

It may work if you use csc instead of home_csc which would reset the phone straight out. I used home_csc which kept my Canadian firmware settings and likely csc

Does Samsung Pay work with Canadian credit cards in your A13 U1? That's the only requirement holding me back from converting. Samsung Pay+Google Wallet cover 90% of the places I regularly shop at.

I only use google wallet so I never tried samsung pay before. I installed samsung wallet and seems it wants a us zip code.
Ok guys so i bought Samsung Galaxy S22+ in Korea. I am from Europe. Reason why i bought phone in Korea was it was like 20% cheaper then in EU + it have Snapdragon instead Exynos.
But as i came back home i was in for a suprise, coz i tried to set up dual sim for the phone, but then i realized i cant do it. SIM card tray where u put physical SIM cards have only 1 SLOT, 2nd slot that was supposed to be on the back side is slighty modified so SIM card cant fit in, also there is no writing SIM2 like its written on fron (SIM1).
Also phone doesnt have support for eSIM, i cant open SIM manager or anything related to SIM cards in settings of my phone.
Dual SIM is important for me coz i use 1 SIM for SMS and phonecalls, its my number, and 2nd SIM is for internet. We are able to buy internet SIM here that have 60GB of data per month and its super cheap, like 7 EURO, so running dual SIM is super cheap version. If i buy internet via my regular phone providers where i can use phonecalls and SMS combined, it cost like 3x more.
SO yeah, i mean i could go for more expensive version and just have 1 SIM but its stupid coz 1 of reasons was i bought that phone is to run it DUAL SIM, i have also my old Huawei P30 pro working just fine, and now i feel dumb for buying another new phone that was meant to replace my old and its not working 100% correctly...
Can i modify my phone to make it work? Install EU version of Android or something? I would rly like to make it work, although even if i make it work i am not sure if my Internet/Phone service provider support eSIM so i swap this main physical sim with eSIM and then use internet one as physical. But ill deal with this later. I just wanna try enable eSIM first if its possible and have dual sim support in my settings.
Any help is very appreciated!
Best regards!
