Well, I answer, because my hands have been several of these units, the problem is not the software, you do not have the GSM antenna or the connector to put it. This would not be problem, but after looking at the schemes of components (for parts) also lacks several things more. I am not an expert in electronics but identify when things are missing.
PS: I have photos of the board of these units, besides that there are also more at XDA one is asking ... and there are several versions, some without sim and SD port, no other wireless controller.
But everyone is missing the antenna. Even that does not solve anything I think.

Refurbished and China seems Frankestein.
If it's a Frankenstein as Joku1981 suggests, run, don't walk, and get your money back.

what can i do now please help me. i upload pic about samsung info.
It's clearly not a Frankenstein, so that's good news. What carrier are you using?
In the first pic at the last line you can read imei cert:NA that mean that your phone has loose its imei certificat.
so you can return it and have your money back or give it to a sepecialized shop to push a new certificat with a box
PS: i have an i9500 and mine show : Imei cert: fail
@sentinelle20: "IMEI Certi: NA" is normal on the S4. I can confirm this because my S4 has the same readout and yet it works perfectly. On the S5 it may make a difference. See here for details.
Ok ggod to know...
in my working i9500 the last line says imei cert : pass

yes my sim work,s fine in any phone , i tried many sim in my phone but result is same. please tell me why some time phone work properly ? do you think its a hardware problem? because i upgrade its room many time but same result.
If you've tried multiple SIM cards in the S4 and all of them aren't working, then you definitely have a hardware issue. Either the SIM card tray has died or the fault lies in the motherboard. From experience, replacing the SIM card tray is both the least expensive route and the easiest, being something that you can do yourself. Replacement trays cost about US$10, a small phillips screwdriver, a half hour of your time, and the foam pad that sits on top of the connector of the original tray.
You purchased this as a refurb unit however, so you should have a warranty of some sort. Take it back to where you got it from and have them look at it.
Hi!
Like the title states my phone (GT-i9515, S4 Value Edition) is unable to register to any other network than 2G.
I'm not really sure if it's a hardware problem or something software related is messed up. So first of - here is what i did:
Checked IMEI - it's correct and corresponds with the one written on the label underneath the battery.
Re-flashed the firmware via Odin (I9515XXU1BPK1_I9515YIA1BOJ1_I9515XXU1BPK1_HOME.tar.md5) -> AP: I9515XXU1BPK1, CP: I9515XXU1BPK3, CSC: I9515YIA1BOJ1.
Checked signal strength under Device Info -> Status: somewhere between -70dBm and -50dBm.
Put the SIM in my primary phone where it's working flawlessly.
See post #3
I already figured, that it seems to be a common problem among Samsung devices (for some strange reason) but all fixing attempts or solutions confirmed working (as far as i can tell) are i9505 specific.
Does anyone know a way to tell whether it's a software or hardware issue (maybe a tool or something)? And is there anyone who has access to a service manual for this device? I know there is one on scribd but i can't download/view it since i have no premium account .
Tell me if i missed out any relevant information.
Thanks in advance!
Silly question, but did you check your APN?
I should add that to the OP. It doesn't seem to be that silly to ask according to what I have read in other posts.
Yes, I did. After i inserted the SIM initially and set the network mode to force 2G only I received a text message immediately containing all the necessary configurations.
If I try to set the APN manually the phone is looking up all available providers and does indeed find some including the one I need to pick for my SIM - even in 3G/4G mode. But if I select the provider (medionMobile, using o2 network) in 3G/4G (WCDMA/LTE) the phone isn't able to register to the network. Only on 2G.
Have you tried a different SIM from a different carrier?
I know your current SIM works perfectly in your other device, but by trying a SIM from another carrier you can determine the following. Should the other SIM work properly in the S4, then we know there isn't an issue with the phone itself, but either the service (likely), or the SIM (less likely). If the other SIM does not work properly, then you may have a problem with the SIM card slot.
Well, i tried the SIM of a friend but he does use the same carrier. I will try that tomorrow at work, there are plenty of SIMs crossing the halls
But let's say it doesn't change anything, is it possible that the SIM card slot is malfunctioning since the phone can obviously operate in GSM mode?
Yes.
Sorry for the late reply. So, I did a check with a SIM of another carrier and well, the phone did not even recognise it. Like there is no SIM present.
To replace a faulty SIM/SD PCB is not much of a deal so I will most propably just do that and post here whether it helped or not.
A service manual would still be much appreciated
The manual for the i9505 version says to check a faulty SIM/SD thing, check the voltage at a certain capacitor. But the PCB layout of the mainboard is slightly different so I would have to guess which is the right one.
Anyway, I thank you for your reply :good:
Hi. So my note 4 emmc had gone so i managed to find another mother board from a n910f europe and unlocked etc. Got it installed by a good phone repair shop and phone booted up fine. Went and rooted it installed norma v19 rom all is well. However the issue i have is reception. For like 5 mins it sees my network fine and i can make calls and sms and use 4g fine. After 5 mins it still shows my carrier name but no recpetion. cant make calls etc. The only way to solve it is to goto settings, networks then choose my network from the drop down list. However again after 5 mins same issue. Now what i tried aftwr is used samsung kies and selected Tools > Firmware Upgrade and Initialization . Then entered model name and serial number. It then downloaded the latest rom csc modem etc according to my country (United Kingdom). Went through the set up and again after around 5 mins no network. if i type *#06# it shows my imei fine. So i dont know what the issue is. One of my friends said they had the same thing with their htc phone and had to actually change the imei on the phone. Anyone have any ideas as to what i need to do would appreciate it. Thanks.
ps i went back to the phone shop and told him to check the antenna wires to make sure it was all put back together properly and he confirmed it was.
bump. anyone shed some light?
i have confirmed one more thing that the imei on the phone is different to the one under the battery so i reckon thats the issue and i need to change it to match. now how do i go about doing so?
Hi,
Have you considered the antenna could be an issue? For what it's worth I replaced the motherboard on my Note 4 a couple of months and had the same issue. I'm just wondering if the antenna wires could do with replacing?
My old charging port melted because of what I suspect was a faulty charging cable, so I bought a new charging port board from China and swapped it in. Phone is now charging again, everything appears to be working except that I cannot get any service from my carrier. SIM card is acknowledged, it even shows the phone number in the *#*#4636#*#* menu, but phone picks up no service.
I am in Canada and have the USA version of the Axon 7. Never rooted or flashed any ROMs, is on Android 7.1.1. Carrier was Freedom Mobile and the phone was on LTE band 4 where I live... And for what it's worth, I also swapped in the old daughterboard with the melted charging port (after I've charged with the new board), phone picked up service right away
I suppose the charging port board /daughter board I got was from another version of Axon 7 and the network chip is somehow not reading my SIM? What do I need to do?
Would greatly appreciate any thoughts or info that could point me in the right direction! Thanks in advance

Correct! You got the A2017 Chinese rf band chip/antenna. You need either a A2017U board to get bands here in US.

Thanks for confirming my suspicions! So I did some more research and found out that the Chinese version doesn't support the LTE bands that my carrier runs, but it does have WCDMA/UMTS Band 2 and 5. I popped in a SIM card from a carrier that have towers in those 3G bands but the phone still wouldn't pick up service. (or am I mixing up WCDMA and UMTS? Those two are used interchangeably from what I've seen)
There was this this previous thread that suggests flashing the full firmware or the modem, or simply getting a GSM SIM inserted into the phone would work. I do have trouble switching the network mode away from LTE/WCDMA/GSM to WCDMA or GSM only.
Any chance I could get the Chinese daughterboard working on the US version (preferably without having to backup data and flashing anything)? If it reaches the 3G network that it is supposed to be compatible with would be great for now!
Alternatively where should I get the US version of the daughterboard? That would solve all my problems.. I have looked on Ebay/Aliexpress again and don't see anything compatible (all from Chinese sellers and some of them dont even have the additional IC that comes with the US version of the phone).

Will keep an eye out.
Still looking and hoping to find ways to make the Chinese board work in the US phone
Have you tried the network operator settings ?
I'm not sure if this will work but its worth a try.
Because of the hardware changes it may not be detecting the network now.
The Chinese board could very well be messing up the outcome.

Yes it's a good idea.
I've looked into that, I've tried clearing all the network settings and it still doesn't pick up service. Only thing I haven't tried so far is a factory reset but then I have tens of gigs of app data I need to back up before I do that..
Did you let your phone scan for networks?
Settings > network > mobile network > network operators.
In Oreo its.
Settings > network > sim card > mobile network > network operators.
Let it scan(this can take a minute or 2) then select your appropriate provider.
Hope this helps
So someone tried to charge the phone with a micro usb cable and ruined the port. It will only charge slowly when powered down. I bought a cheap chinese charging port board 15.99 plus 2.00 shipping and now it fast charges( off&on) but have no cell service. So I put the original back, and the cell service works. THe chinese board has this E222034 and no QR code, and the original has a QR code with E315850. My phone is a usa model, and does anyone know where to get a compatible one?

There surely are U boards online, though maybe you'll need to buy a scrap phone
Any luck sourcing a U board?
Same problem here. Tried boards with IC chip and without from AliExpress and Ebay - none of them are working. Sellers are claiming that all boards support A2017U.
Searching for any networks give an error right away and refuses to search.
Any help with finding A2017U compatible board is greatly appreciated.
Here for the same search...
Bump. I'm in the same boat, I have a broken pin in my charging port. I was going to order one on ebay that claims to be A2017U compatible but after reading this thread, I'm skepticle. Did anyone managed to find a working board for the A2017U?
Correct board

Thanks for the post. I couldn't find the exact listing for the ad in your post, however I did find some with the original IC chip manufactured by Jiaruila.
Can confirm if that indeed is the brand of the board, thanks.

Hi, I have an A2017U but bought an A2017 replacement charge board. Were you able to get this board working (functioning cell service) with your phone either through flashing a different firmware or modem file? Thanks.

Hi All
I'm looking for some help please!
I have fitted a Chinese Android Head Unit to my car. I have a 4G/Wi-Fi modem into which I have fitted an O2 Pay-as-You-Go SIM Card. The SIM card connects to the HU by USB, but rather oddly the modem uses Wi-Fi to connect to the Head Unit (for some reason not using the faster and more reliable USB, but that's not the question).
So, I can connect to the Internet and use up the time on the SIM card - that's all OK, but, O2 will only top up the card or tell me the outstanding credit if I answer a text message that they send to the SIM card - which of course has no idea what to do with a text as it isn't in a mobile phone. Their security question is "what is your most dialled number ?" - but I don't ever dial out. So I have to top up blind by going to the O2 shop and handing over cash!
The 4G/Wi-Fi modem is now in the cars roof column so not easy to get at!
Do you have any suggestions as to how I can top-up? My ideas were:
a) Find an app that turns the Head Unit into a mobile phone that can receive and make texts
b) I know that the 4G/Wi-Fi modems you plug into laptops come with software that allow the provider to connect directly (without texts). Is there one of these for Android?
Hopefully I am just not looking in the right places - I don't want any solution to involve my mobile phone as the idea is that my car can support me if I lose my phone.
Cheers
James
Well.. I just googled "02 sim top up"
seems like auto-top up is a thing. and it seems that you can install a "my o2" app, on the headunit or phone, and see the balance on there..
maybe have to put the sim in another device to get a text to link it to a account or something.
Hi pafo42
That was easy - thanks, I'll give it a try.
I did go on line to O2 and consulted two of their 'Gurus' on different occasions. Suffice it to say they were completely useless. Well I'm assuming that they are Gurus in the sense of an authorititve teacher, but I guess they are Gurus in the sense of being Hindu Spiritual Leaders and so have no particular knowledge of Mobiles and Android, etc.
It will be interesting to see if my Head Unit comes up with the same display as a phone - not sure about the fingerprint part either but it is an avenue to explore.
I also searched Google play for an app but I guess I failed there!
Cheers
James
