I am thinking to buy the GT-N7105 antenna and install it on a GT-N7100 then flash the software of a GT-N7105 on it, now there is no topics on this any where that I checked so here I am ...
My questions are:
[1] Have any one tried that, is it even possible?
[2] What are the possible complications?
[3] Is there any other differences between the 2 devices that may effect the process?
Thank you

1) No one has tried that I am aware of. I doubt it's possible either because the LTE controller chip probably isn't even physically present on the main board of the N7100; You'd need more than just an LTE antenna to get LTE to work.
2) Complications? The whole project. I mean, you probably don't have any of the precision equipment needed to properly install and solder new controller components onto your N7100 in the first place (assuming the N7100 and N7105 even use the same PCB at all!)
3) As mentioned already, you're likely going to need to install the LTE controller hardware before the antenna. This assumes that both the N7100 and N7105 use the same PCB; it's possible that they don't. If they don't then there's nor point in bothering, which bring me to my question:
Why? Why go through this process (assuming it's even possible in the first place) just to convert an N7100 to an N7105, when you can just go out and BUY an N7105? I mean, if you wanted an N7105 in the first place, why didn't you just get that?
Don't try that, its not going to work.
replace the main bored
but the main bored will cost about 3/4 of the phone price
Scratch out the "0" & draw in a "5" then
While on internet just lower your expectations.

Exactly. Change build.prop to change about phone.

well hope every one is done with the mocking .....
to Jade Eyed thanks allot for your reply here is my follow up
Well first of all I am one of the first few who got GT-N7100 even before any signs of GT-N7105 shows up, and lets not forget that Samsung did falsely advertise the Note II as a 4G device since the beginning with out mentioning any model numbers.
Where I stay just started getting the 4G services so it didn't matter to me to me at first, and it isn't cheap to just simply buy another device and have it shipped to you "they don't sell it here"
hope this clears up why did you get this and didn't get that drama...
I have some knowledge about manufacturing and I know it's very expensive to manufacture different variants of the same thing as totally different processes. That leads manufactures take a different approach to achieve just that.
[1] they produce the exact same parts with the exact same connectors how ever they simply don't put in the parts that connects to those connectors and make the difference between the variants.
[2] they produce the exact same parts for all the variants in early stages and just have it differ in a later stage of production (they print the same boards and send it to 2 different production lines where even the connectors aren't put on the board .
now I am not sure which method Samsung is using. If they were to use the first method that means it is as simple as i said in my first post (just get the needed parts and install them and then deal with the software)
how ever if they used the second method it would simply be near impossible to do as you really would need extensive knowledge of their design just in order to do that...
I will take a look at the parts and report back how ever I would like to start a real project out of this and see where does it go
Sorry to mock but your idea looked a bit daft as you can read plenty on XDA about the different variants of note2 around the world to realise that its far more complex than just swap a cheap part.
Better to sell yours & get a 7105 from
Negrielectronics for great price & they ship to loads of countries.
might have been possible I converted an SPH-L900 to a N7100 years ago
now that 4g is all that is provided in my country I need to bump my backup phone up to an N7105 , or swapout the internals of my cracked screened / broken cased n7105
I have two pieces of ZF2 ZE551ML at home. One is my and the other one belongs to my wife. My wife's phone had a broken mini USB port - the first 2 pins from the left were visible - the plastic had broken apart. Firstly, I did not relaise it could be the problem, luckily I managed to change the whole PCB including the broken USB port, however after this change the phone is not being detected by a PC, nor it is fast charging. As I have two phones at home, I checked performance with the other unit and unfortunately, the other one does quick charge and is detected by aPC, so it is not the cable, neither is it the missing software.
I bought another PCB and changed it as well, however still no joy. Does anyone have any brilliant idea how to fix it. I should also say that all other or most of the functions of the phone are working fine (at least those I managed to check: GPS, Wi-Fi, GSM+dual SIM, torch, bluetooth, and so on).
The only problem is that the phone loops on the SMMI Test #1 and is not going any further. I have also tried to detect phone by adb, still no joy. The phone is not rooted!
I have my personal suspects that it could be the faulty main board or a software bug. Any ideas how to fix it?
My phone is running LP 5.0, soft: LRX21V.WW-ASUS_Z00A-2.20.40.198_20160930_8756_user044030427_201501060109, kernel [email protected] #1 Fri Sept 30 15:31>23 CST 2016
Sdcard slot is working?
I would check the connections on both ends of the flex cable with the sim and sd slots on it.
I am having the same problems (because of the busted sd slot). I ordered a new flex cable. When it arrives (approx. 2 weeks) I'll know if that was the cause.
Yes, SD slot is working and both SIMs, so the phone itself works fine, only very long charging and is not detected by a PC.

may be the pcb you changed is for different version. try replacing it with your other phone if you have the same model. post if works.

Hi, I did changed both PCBs between phones. Firstly, I had the same problem on both phones, then I made better connections and the batteries started to warm up. Finally, the new one works with the other phone, the old one from the other phone still creates the problem. Probably, it is not the PCB then, or USB connection. It must be something else.
Anyone, any idea?

try fashing raw firmware
on motherboard you can inspect or clean the connector where pcb connects. use magnifying glass to inspect connector
Ok, I actually would like to flash the raw firmware, however I need some guidance here, as the phone that has a problem, is not rooted, and it cannot be detected by any PC now, so I am stuck in the middle and do not know how to proceed...

i am little confused here... you changed pcb on one mobile and fast charger do not works on that. you have other mobile which is working perfectly. both are same model.... if right!! do the following thing to find out...
Phone A:- changed PCB. no fast charge, not detected by pc.
Phone B:- working perfectly normal..
now we want to guess if pcb is faulty or there is issue with flex cable or any software related issue..
remove motherboard from phone A. and install it in Phone B.. if on Phone B. things works well then definitely its problem related to pcb.. if things don't works on phone B too. then it may be a firmware related problem..
raw cannot be installed without pc..... the thing you can ty is updating firmware from sd card via recovery mode.

That is correct, I say it again - I have two phones, same model, same software, kernel, etc. One had a damaged mini USB port, so I purchased 2 PCBs which have mini USB port souldered onto them. I bought them twice, as I was not sure if the first one I got was the correct one. Now, after your first message I changed the PCBs between phones and the result is the same, phone A (which is ok) works with the replacement PCB, and the PCB from working phone still does not work with phone B (the one that has a problem).
As a second step I replaced motherboards between phones now, and the result is still the same, meaning the motherboard from phone B does not seem to work better while it is in phone A body. The symptoms I'm struggling with are: charging takes over 8-9 hours, so it is considerably extended charging (battery is original factory battery 3000 mAh), the phone does not fastcharge at all and it is not detected by any PC.
The phone is not roooted so, I'm afraid I cannot make any changes to firmware through recovery, as it needs to be connected by a cable to a PC, unless there is something else I can do about it, but how to get any further?

Is your ext. sd being seen in file manager ?
Can you get into 6.0 recovery ?
If yes , you can now downgrade which will reset your fone , With a factory reset in the process , check my signature below.
Your fone not being seen maybe driver issue if other zens too are not being seen...but ..let's see what happens after downgrade.
After downgrade if still slow charge, reboot while connected to charger.
If same prob ..hardware !

Thanks, I was not so deeply checking all available options. SD downgrading worked well for me, however the problem still is in the phone. However, I discovered a few positive and negative signs, which tell me that there is something else - could be the connection - after upgrading to MM before the phone was restarted at least 3-4 times the screen was not going to sleep mode after a minute, it was coming back on and on and on again. After 3-4 restarts it behaved normally again. The same thing happened after downgrade to L.
Another positive discovery is that the SMMI test now works well and everything is ok now, before it got stuck on the 1st or 2nd test and was not going any further ....
One more spot, which was very hard to catch as it popped up for a 0,1 second but dissappeared then quickly so I had to record it with the other phone and play very slowly on the PC - it looks like the Asus cover window pops up and it says - move your finger around the circle to get quick access to your preferable apps and there is also a blue button: Do not show again . This is flashing now and then and I do not have Asus Cover, so the behaviour is quite odd to me.
I have a feeling that there might be something with connections, but really I do not know what else - I checked it 30 times and made sure everything was properly alligned and tight when I was changing the PCB with micro USB port.
By the way the other phone works well on PCs, so I must have all drivers installed, it is just the second phone that is half bricked... I'm wondering now if maybe flashing CM 12 or 13 will help, however as it is not rooted probably it will not work via SD card... or? Am I looking in the right direction?
Buddy , its hardware so software tweaks will be useless .
Buddy, we are on the same ****ing boat.
I tried to go back to 6.0,but i got my phone bricked and now i cant reverse it back because i need usb connection to the computer and simply it isnt recognized.
I suggest you to send the phone to the asus assistance centre or to buy a new usb port for your phone,as it is clearly damaged like mine.I need to do it too so if you want to wait me first so i can check if it works,ill maybe save you some money.

Well, my phone successfully reversed to Lolipop, and I changed the USB port, I talked to Asus authorised service centre and they said it will cost the price of the phone, so I just give up, as everything works, but not the phone with the computer via USB and not the quick charging. Asus centre said it is a motherboard failure, but I'm asking how is that possible if all other functions work well???

Yes, I see your point, but I cannot imagine how is this possible, when all other things work well on the phone and the SMMI test shows all sensors working properly?

Ask yourself the same 2 questions again once more
Is your phone recognised by PC ?
Is fast charging working now ?
If answer is no after downgrade .
You know the answer
i changed mainboard and working
well, i have the same problem and i try the following possibility and all unsuccessful.
1. i tried 3 different pcb still no luck
2. i changed sim flex still no luck
3. i changed battery still no luck
4. i changed lcd and digitizer completely still no luck
5. i wiped cache from android recovery MM still no luck
6. i wiped data and factory reset from android recovery MM still no luck
7. i install same latest os (MM) for ze551ml from sd card still no luck
8. i use original ac adapter and cable and tried working different one for every step.
so i want to ask a questions. can it be ground connection somewhere on cases? or motherboard
i am tired but problem found. it is exactly motherboard problem. i bought used original mainboard and all is working.
Note: other mainboard using same android os version so it is not os failure.
Hello everyone,
the motherboard of my S4 mini duos (i9192) failed, probably the EMMC, and I need to replace it. Since where I live the 4G/LTE signal is so much better than the 3G and I don't need the dual SIM anymore, I was thinking to buy the i9195 motherboard and substitute it for the original one.
When looking at the components of my phone, I saw two other parts which seem to be related to the 3G version (i9190/2, as written on top of them): the USB connector board and the antenna on the top part of the back housing (the one with "3G" stamped on it), see the figures here.
So I suppose that I should be fine by replacing all three pieces with the i9195 version, also given that they seem to be the only 4G-related pieces in the phone, as per this thread and the video linked therein.
Has anyone tried this? Or, do you have any comment/advice?
Thanks in advance!

it is a gamble I think, it has been reported that even swapping the connector brd for a new one sometimes didn't work with older motherboard, though swapping all 3 it might work for you, but no guarantee. Also then you might have problem loading software & need jtag
But is there much of a price difference to buying a new phone?
Ok, I bought an i9195 used mainboard together with the USB connector board for 30 €, mounted them and flashed the latest Resurrection Remix. The phone is working pretty well (a really big upgrade from my S3 mini) even without changing the middle frame. Actually, what is missing on the middle frame is the 4G antenna, so the 4G is not working at the moment, but for the rest no problems whatsoever.
I'll try to buy the middle frame in the future and report if the 4G starts working, or if the circuitry got fried for the lack of the antenna.
@IronRoo thanks for the suggestion, the main point going for a new phone is the price of one with screen size less than 5" (this is 4.7" and is perfect, bigger ones are uncomfortable to hold for me): the cheapest one is Samsung A3 which is 200 € at the moment. Also, I'm also kinda annoyed by throwing away a phone that could be fixed and given new life.
Strange... My 9192 also fail EMMC some months ago and I also replaced it to 9195 from a local shop. It just 2 case of failing EMMC is seems like a design flaw? Maybe?
Anyways my phone is fine except for battery life I don't get even 1 full hour in performance mood also on RR ROM android 7, and it's my secondary device so I don't use 4G on this device can't report back how good probably I won't even get bit of charge xD

Hi there. I recently change the charging board on my note 10 plus but since then I have had no signal. It seemed a pretty easy swap with no complications when fitting. Anyone have any ideas?
My phone is a note 10 plus N9750.

Ah that will be a shame, I was hoping not to buy a new phone just yet. I have ordered another board just to see if that fixes it.
Wrong PCB. There's more than one variant for the N10+!
It happened to me, no phone or internet connection.
Check the old PCB for it's PN, that's the one you need. It will work perfectly once it has the right part

Ah I was wondering that. I have the N9750 as I was being cheap and got it from abroad on ebay.
I stupidly chucked the old one away as it looked like it was all fine but it was just wifi calling I had.
