Hi
Not sure where to post this but figured someone here might have an idea if this will work...
I have 2 Oneplus X's, one of them E1003 has LTE Band 3, and the other E1005 which doesn't Have Band 3, and my carrier only supports Band 3,
The E1003 has a broken screen so I have no use for it,
If I take out the Main Board of the E1003 and put it in the E1005 body will I gain the new bands? or is something with the antennas of the smartphone not the modem chip?
Thanks in advance!
This is kind of like saying: if I take the screen of the E1005 and put it on the E1003, will it still be an E1003? =)
That aside, I can't imagine that the antennas will be that much different. I'd say if you can actually connect them up to the board, they probably will work? (probably... I think.)
Swapping the mainboard will work.

Yes, I was wondering if the antenna hardware would give me LTE Band 3 with the E1003 motherboard,
btw if I switch the motherboard will the other components of the phone work with the new board, or should I replace other components too,
I ask that because iPhone for example requires replacing home button with the main board
Thank You

I have T-Mobile and I want to buy the International Samsung Galaxy S II. I understand that the International version does not support T-Mobile's 3g frequency band, and I would be limited to 2g speeds. However, I was wondering if it would be possible to buy an external antenna to be able to use 3g speeds. Or even better, is it possible to replace the internal antenna?
No and No.
DO NOT DO THIS UNLESS YOU WANT TO KILL YOUR GS2.
Sorry for the bold, but despite there being no rhyme or reason for it, I came across a thread which illustrated this fact from multiple people who tried external antennas, and here's what happened. The antenna worked, they thought all was good, then they disconnected the antenna, no signal. EVER again. I guess what happens is when you plug in an external antenna it pushes some contacts apart which breaks contact with the internal antenna permanently (supposedly a few that were very handy with a VERY tiny needle were able to fix it). Don't ask me why Samsung would design it this way while leaving the plugs exposed but that's what I read. Just wanted to make sure you didn't find out the hard way
In other words, the jack is there, and you can find adapters for those jack(s), but you really don't want to, unless you want to ONLY use external antennas for the rest of time (not most people).
EDIT: Whoops, forgot to add the most important part. Antenna has NOTHING to do with the fact that the radio doesn't support t-mo's frequencies. It's like having an antenna designed for HDTVs, and hoping to get hdtv on your standard def tv. Antennas don't "translate", they're all just fancy coathangers.

"antenna has nothing to do with GSM OR CDMA bands." its the radio chip that does the work.
Please use the Q&A Forum for questions Thanks

Understood, thanks for your help guys. Is there a way to mark this as [Solved] or something?

Hello to all
Yesterday I go to shop near my home the fix androids and iPhones and the tech tell me maybe is good idea replace the board (IMEI us different from the back and can't get signal in simple mobile same as Tmo well my question is how I really know if the board is damage?
Thanks in advance for any help!

Well have you tried different modems as well as the correct APN settings for those carriers?
I do not know how this "repair shop" gets their hand on the logic board to begin with.
I had been looking for a logic board, but NO ONE has it. Not even the supplier of Samsung repair parts. It is not for sale.
So, it sounds like they may be trying to trick you and charge you a big bill to "fix" it, when the solution is most likely as simple as flashing a different modem.

Yes Sir but let me try it again so if the APN is incorrect this matter on signal and calls? i mean with my skyrocket i never put the APN phone automatically loads (Tmo apn not simple mobile) and works better than the simple mobile itself

maybe but i flash various radios and roms with no luck BTW did you can recoemnd me a "work" rom/radio combo?
update: my friends test this with their att sim card and works perfect (4g LTE) not sure why not work on (Tmo) i test with Claro too try to make a calls but freeze, laggy and screen goes black sometimes can talk but then signal drops :crying:
So exist a software or code to test the phone internal hardware?

I am sure we all know about the lack of support for CDMA on the OnePlus X. I was wondering if it is possible to create a sort of relay that uses a CDMA sim and broadcasts to a GSM phone and vice versa. I don't know if this is an existing thing, or possible, but I thought it would be an interesting idea to research. Does anyone know anything about this? Is it possible?
Thanks,
Lev
Also, sorry about my ignorance on this topic- I only received my OnePlus X today, and it is my first phone.
In fact you want to operate a GSM BTS (for your OPX), that will communicate with another BTS using CDMA frequencies.
So like 2 BTS, a laptop, and batteries in a backpack, just for using your OPX in CDMA regions.
Why not, you could do it with Osmocom I guess.
But, being more serious, OPX supports some WCDMA bands. If not sufficent, just buy another phone. Nobody will ever bother to work on that.
I was reading that two of the missing bands were software locked. Is this the case?
I just decided to attempt this as a school project, I was just wondering if anyone had any knowledge or advice they could impart. Other than the common, "You can't do it" advice.

your post is very ambiguous. are you asking how to get dual sim working on a specific ROM youre running?

I don't know what he is asking but I know a hardware hack to get dual SIM and SD at the same time. Pretty interesting

i believe he is talking about the phones with dual trays such as the S9. All of the phones with dual trays built into the chassis are physically able to accept a dual sim tray, just not all mobos have been set up to utilize a dual sim setup. The G960F and G960FD are the same phone, the D just stand for dual sim. AFAIK, nobody has done a tear down on a FD vs a F to determine if any hardware differences exist. Completely unrelated side note, its really hard to type when a kitty is pressing its head against your hands LOL!!

Lol. I believe the s8 models f and fd are compatible. Just needs the firmware and a IMEI tweak. I'm pretty sure the hardware is there. I'm actually been looking I to it on my 9650 as it has the hybrid tray. Im pretty sure it works. Just no IMEI attached to slot 2. I see guys somehow slapped slot one Imei onto slot 2 so just matching IMEI on both slots.

see, now would that fall under imei cloning? Is it problematic to "clone" your own IMEI within the very same device? If its all good, then id like to see it discussed a lot more. Im going to Romania in a few months and would love to have FD working on my G960U. I thought you had a 9550 not a 9650

Imo it wouldn't since it's same device same IMEI. Only issue is the s8 and up IMEI are written with cert files. So you would need more than likely a paid service.
Maybe this would work? Would make me a little nervous about waterproofing TBH but kind of a neat technical concept: https://www.simore.com/en/mobile-phone-accessories/samsung/galaxy-s9/
You might need something like this to make it work: https://forum.xda-developers.com/t/xposed-unlock-dual-sims-sdcard-on-s9-s9.3888952/
Does anyone think there's a chance this tablet has a modem in to that can be enabled by porting over parts of a dump from one of the cellular versions? Long shot but not use to wifi tablets even having the pins for sim card.
i don't think so, if it has been designed to be working without a sim, there's a reason for it. the only way would be to replace the entire motherboard with the t975/t976 version, so you might as well buy the sim version.

Oh I get it, this is just the first wifi only tablet I've had, that HAS the pins for a sim card, I'm not taking it apart, but since it has a 865+ it would be insanely easy if there's a teardown to tell if it has the hardware, since the modem is now a separate chip with this snapdragon, granted you would need to decan the motherboard to do so,
Samsung used the same SIM/SD Card combo tray for all S7/S7 + models.
You'll notice the filler piece on the opposite side of the SD Card side is shaped like a Nano SIM..
The filler is removable and is marked under the black sticker as a SIM slot.
That said, I doubt Samsung is going to include the radio package in a disabled state on a Wi-Fi only model.
The one teardown video I could find of a Wi-Fi only model S7 did not show any cellular radio antennas. I can only see Wi-Fi leads. Definitely do not see any 5G antennas.
