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' currently thinking about getting the Xperia XZ.
I'd like to take the Dual SIM version because of the bigger storage. However, I don't need the Dual SIM feature and rather have quicker Firmware updates.
Therefore I'd like to know if I can flash the Firmware from a single SIM XZ to the dual SIM XZ?
Will I still have the 64GB of storage?
Thanks in advance

Flashing a single sim firmware on a dual one can throw your Device in a bootloop, although I've never tried it but I think flashing the wrong modem & baseband can definitely screw up your Device.
Thank you for this answer, although I have hoped for something more positive
Okay, I think I'll refrain from buying this phone then. Hmm...
Sorry to dig up an old thread. Did you end up trying this? I'm curious too.
Cheers
This should work. Remember having done this (actually the reverse) some years ago flashing the Xperia M Dual FW to the single SIM variant because -interestingly- the Android version of the Dual-SIM was higher (believe it was 4.2 vs. 4.1 or something). Anyhow, if it doesn't work, well, just flash the correct one and you're up and running again.
It may work if after flashing the single sim firmware, you use flashtool to flash only modem and baseband from a dual sim firmware.
Has anyone figured out how to do this yet? Is it safe? I want to flash a Single-Sim variant on to my Dual-Sim XZ as well, but I can't find any guide/tutorial on how to do it and also how to get the correct modem and baseband files.
Can anyone assist with a quick guide?
I got this e3 that i flashed 3 different stock roms, and i can't get sim card to work on any of them. With or without sim installed i get a failed check picture and i can't use sim, tho other things work just fine. I have tried a central european rom, a rom made for my counrty, but im not sure weather the sim card is from that operator the rom is made for.
I took the phone form a frined to try and fix it since it was stuck in boot loop, so i've handled that and i'm not sure how to fix this :crying:
The roms we apropriate for the model, d2203, used the both latest one and the one before.
Did you resolve this?
I found that if you run flashtool on pro mode it will allow flashing of simlock.
I don't know exactly what's that but I hope it (and google) helps you
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.
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?
Hey everybody today i received 2 op9 both are in le2115 but one was single & another 1 is dual sim

Anyone have Idea about it?
If anyone able to help or even give me idea about it please DM me
I'll Donate If anyone able to solve this issue (JUST DM ME IF YOU HAVE ANY IDEA ,MUST)
You sure one was not just converted. The dual sim is correct as that's the global model. We're these phones new or used?
Both are new and not converted coz I flashed many time by same rom
