I am trying to fix this for a friend of mine, it is a clone of a Samsung Note 2. I know it is a chinese clone but I have no idea of the manufacturer or where to begin looking. My friend like a dumbass decided to try and flash a ROM to it and it semi-bricked the phone, it does connect to my PC for a few seconds and I have looked at the thread of how to unbrick a MTK 6598 chip phone but without knowing exactly which manufacturer this phone is from, I have no idea where to begin.
I think it might be a Star S7198 or something like that but I am not 100% sure. So, anybody have any ideas? If it helps, in the close up of the sim card and SD card slot, the sim card is on the left and SD card on the right. The sim card slots are stacked, it looks like a regular sim card on the bottom (#1) and a micro sim on top (#2). Other than the N7100 listed as a model number there is no identifying information anywhere that I can see.

I always get that grey icon of a sim card with exclamation mark & cannot make any calls. Restarting the phone doesn't work, neither does removing the sim card & putting it back. But imei works and the sim card works aswell . Tested it in an other phone.
Is there any possible way to solve this?
Maybe your Sim-card slot is unclean? Try to clean out it by compressed air or degrease. And also try to wipe chip on your SIM card.
done
Try downloading hck tool
Try usin a small paper sheet on the sim to push it down.. It helped a fren o mine!
Gentlemen, I have a pretty strange problem when it comes to the SIM card in your phone. After installing the ROM - Dirty Unicorns - SIM card I fell as if burned. I checked on various Roma to no avail. None at all read the SIM card in the phone. But after installing the software orginalnego Samsung Sim card work jakgdyby nothing had happened. But as soon as I do root your phone card disappears again. I'm sorry for the mistakes I use Google Translate to communicate with you
Hi,
Believe me - I tried all the things I found searching the web - this is my last resort..
I have Jiayu S2 Advanced 2/32GB, It stopped detecting SIM cards after system update.
Original Adroid was in version 4.4.2,
After this happened I tried to change ROM with the ones available on needroom portal, as well as Jiayu website and Jiayu.es
Tried to upload ROM with SPflash and CWMRecovery - I went through different 4.4.2 version and 4.2.2 - everytime ROMs were working fine, but SIM cards are not detected.
At the same time I observed that all 4.4.2 Android version did not even notify about SIM cards missing - only 4.2.2 did it.
IMEI address is correct (the same for both SIM cards) - tried to overwrite it anyway with the same numbers - but still the same...
I'm not an expert, but I think radio file is included in ROM package when flashing with SPflash? If not - where can I get it and how to upload it to the phone? Any other ideas?
Attached screenshots from system set up and Mobileuncle Tools - on the SIM 1 I see some signal strength changing and Radio is ON, no matter if card is in or not - status of those doesn't change if I put SIM card in.
ONE MORE THING!! Just found out - when telephone starts up there's standard info 'Slot 1: No SIM card detected, Please check if SIM card is ready' and the same message for SIM2, but when I clear messages and then on working phone I take out SIM card from Slot 1 and put it back 1 second later I get the same message again 'Slot 1: No SIM card detected, Please check if SIM card is ready' - this make me believe that SIM actually is detected, but somehow not recognized! The same thing happens if I "play" with Slot 2. Please help!!
Did you manage to fix it? I am having trouble myself; The SIM cards are detected, but cannot connect to the network. The IMEI was blank after a couple of ROM flashes, but I have restored it. Still, no luck... Probably the efs folder or something like that is corrupted, but I have no backup.
Same issue in Jiayu S2
background: I bricked my redmi note 3 in the worst way so I had to use test point method to bring it back to live. So I disassembled and assembled it during that process. Both sim slots were working great before that.
Symptom: sim slot 1( the micro size) alone is working fine. When I put only one sim card in sim slot 2 ( the nano size which share space with micro sd card), it show sim card detected then no sim card then sim card detected then no sim card and repeat this forever. When I put two sim card in both of slot 1 and slot 2, neither on can pick up signal and sim 2 showed up and disappeared repeatedly again.
Really hope someone can point me to a direction to fix this. Thanks.

First go here and follow the steps.
And then flash non-hlos.bin from the ROM which is working for you. And, in this process, my IMEI got lost and I manually had to enter using the tool in the above specified thread.
Best of luck

Hi guyz, newbiw here, feel free to move this post if posted in the wrong place...
A few months ago, I bought a cheap generic "chinese" phone (only identification of it is "Model 6x" and some IMEI numbers). I has android 5.1, supposed to have like 3gb of Ram but had only 1.5gb, the seller did that on purpose, so I got a refund. So, having a free phone, I want to use it...
This phone has a "3-slots" slots, so micro-SD card, and 2 SIM card can be used, but there were no indication on how to put them in. On my first trial, I had to open up the phone to get my sd card back since it got stuck behind the holder. And then I found out the upper slots were for SIM cards (put them back to back) and the bottom one for micro-sd cards (contacts up or down?).
I tried to "boost" the RAM with an SD card as I read on a tutorial I can't find anymore. When I put the SD card in, and selected an option to use it as RAM, I must have put the card in the wrong slot or something, because it just went black and wouldn't do anything. I just left it in the box for a few months after that, and stumbled upon it a few days ago.
I am able to get in recovery mode, I wiped all data (user and cache) multiple times, rebooted, ect. I tried to plug it to my computer, it can't find it. It doesn't charge anymore either. The only good thing it did since I found it, is to find my SD card (after a few trials of putting it in the right way) in recovery mode.
Is there anything to do with that, or should I forget about it?
Thanks a lot!
