Hi! My Second SIM Slot got locked up after installing a custom ROM. Is there a way to keep the second SIM Unlocked, I tried changing the CSC to the default one and it's still the SIM. BTW I got mine from Smart here in the Philippines.
If the second SIM is important, I'd go back to the working setup, until I researched a working, DS Exynos (?) ROM.
Why don't you install the original ROM, that supports Dual SIM capabilities?
Try that and see if it works.

So Ive been trying this for such a long time its disgusting. The thread title is my own conclusion from my research throughout the web but I may be wrong in my conclusions.
I have a Huawei G510 since last year. As soon as I got it I rooted it and found a ROM for it. The ROM is a dual SIM ROM and I remember doing something related to a cust folder or something, but I'm not sure. Fast forward to the last few weeks, I want to update to 4.4, and I download a bunch of roms, all of them work except for 1 thing: They dont recognize my SIM Card. I go to Status in the settings and everything about the SIM is "Unknown".
I found a Lewa ROM based on JB and that one was by chance a dual SIM ROM, and guess what, its the only ROM that works. So thats how I concluded that installing a dual SIM Rom must have changed something so that it doesnt recognize my SIM anymore?
So what should I do? Thanks in advance!:good:
anyone? any help is appreciated
Hi guys. I recently got a Moto G and i knew sim card was not detected by network. Phone it detects it,even apn's. Problem is,it says on operators selection that my sim cant register on the network. My primary phone is a M7 in wich i use my sim just fine.
Also,it is possible to be a cdma phone,but why it has a sim slot and model number as international version? Anyway,in settings it says something about a baseband and not about radio version. Also my htc has baseband version not radio version and it works on gsm.
Anyway,is it possible to flash only modems(radios) on this phone w/o risking of bricking it? I wanna flash GB radios.
And i kinda dont know the whole process since i never had to do it on any of my phones. I would be very thankfull if someone can put me in the right direction with this. Thanks!
Edit : i forgot to mention. I am on cm 12.1 unlocked with latest bootloader.
You should flash stock ROM and try. Sometime CM ROM not work.
I tried Cynogen and several other rom the second slot is not working for sim can anyone confirm this
shortcut way is try to flash official stock rom once and begin from start.
and check the sim slot (hardware).
Hello everyone, have a nice day and best wishes for the new year! :highfive:
This is my sister's phone, a Samsung Ace S5839i with stock Gingerbread 2.3.6 as second phone with Vodafone carrier. Years ago it was unlocked and rooted at a phone shop and everything was fine. At some point, she issued that the phone stopped connecting and wouldn't work with Vodafone, but strangely it works with other carriers.
So now I have the phone with me, I have tested older Vodafone sim cards and they work fine, tested other carrier sims and they work. I have tested 2 new Vodafone sim cards (mine and my sister's, which are both new and work on other phones) and both fail. The phone boots and doesn't ask the pin code. There is the icon in the statusbar with the sim card and an exclamation mark like there is no card. The radio signal is ok, IMEI is ok, it says "Insert SIM card" when I try to enter the Network Operators in settings menu.
I have downloaded a stock rom with newer PDA and modem versions and flashed them with Odin, but no luck, everything is still the same (except the flash counter...). I wonder if searching and flashing even a newer modem would solve the issue. Or would a newer Android version if there is. :silly:
It looks that this is a Vodafone related issue with the new cards, but all they say is that the sim is operative and won't help.
Hi, my phone is currently locked to carrier smart. Before flashing my first rom, as long as I had 1 smart sim card on any sim slot, the other one can read any other carrier. After flashing rom, if I insert 1 smart sim and another one from a different carrier, I get the network lock notification. It works fine though if I just use 1 smart sim only, or smart sim for both sim slots.
Any ideas on how to revert this? Or are there any unlocking apps I can try for free? Thanks!
Got that same phone few days ago, and as far as my knowledge goes the F and FD version shouldn't be network locked as they ship world wide (international model with exynos chip). From what you saying, its after you flashed the ROM you got the second card locked, so my first question would be what ROM have you installed ? and can you link me to it. 2nd idea or question.. Did you flash the FD ROM or the F one? the F is a single sim version, it does have the second slot in there actually but its disabled or locked, so it might be that the 2nd slot is disabled or something. 3rd, have you tried other ROMs ? or even stock firmware, you can confirm if the ROM is the issue.
And my advice is to not try the apps, most of them are either outdated that only work with exploits in old android versions, or a complete scam. Waiting for your reply.
Hi Salazar, thanks for answering! I already forgot what rom it was - that was about 6 months ago. I remember then I had a backup of my EFS and baseband using TWRP. I remember restoring those when I first encountered the problem - that's how I got my 2nd sim slot working again. Problem is I've already lost that backup, and when i reformatted my phone yesterday, the 2nd sim slot wouldnt work anymore. Just tried flashing a number of custom and stock roms earlier today - problem still persists. If you happen to have the same device (G930FD) - mind sharing your TWRP backup for baseband and EFS?
