A2017U shows "No service" after charging port board change - ZTE Axon 7 Questions & Answers

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?

Time to take the soldering iron! Lmao
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.

First one is cheaper by $5, both are the same brand. I emailed the sellers for clarification but both were of no help.

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.

change teh sim card possible?

Gentlemen / ladies
first off i would like to thank this site for all its help so far , i have installed colonels rom and i am delighted with it , however i have a small question.
i purchased the sprint mogul while visiting the states last week as i needed a pda and it seemed to fit all my desires , however upon bringing it home i noticed that there was no simcard slot so i cant use it here in Ireland (we seem to be a bit behind the times ) spoke to a rep here and i was told the simcard is inbuilt and it would need to go back to htc to be changed , now that isnt really feasible at the moment so i was wondering if it was possible for me to change it out or if that is even possible , i dont mind taking it apart but i can find no info on where the sim goes or if there even is one , sooooooo just wondering is it possible ?
thanks again for all the help i have recived from other threads on upgrading and thanks to the colonel for releasing a class rom
regards
To the best of my knowledge, CDMA phones don't use sim cards at all. I could be wrong.

Uh, for in Ireland you have a paperweight. There is no CDMA outside North America. There is no sim in the Mogul, and nothing in it can be reprogrammed to make it work on GSM. The entire radio portion of the phone is made for CDMA and specifically Sprint.
Sorry, but you'd be better off ebaying it and getting a GSM device.

To my knowledge, this statement isn't entirely true, as I believe that South Korea and maybe China has CDMA networks...but I could be wrong...
Everything else you stated is right on though!
Oh boy.
In a nutshell:
2 major types of wireless protocols:
GSM and CDMA.
GSM is a sim-card based allowing phone portability, and exists on a world-wide market. The sim card contains your identity, and switching it into another phone causes your identity to follow.
CDMA is phone-based, meaning every phone has a unique ID that broadcasts to the tower. That ID (sort of like the VIN number on a car) exists on only your phone, and represents your ID on the network. This actually existed long before GSM and SIM-cards, and is at a bit of a disadvantage because you can't switch phones whenver you want. Your provider has to switch it for you.
Here in the US, we have both CDMA and GSM networks now, however CDMA has been around longer, and so it is still arguably the more common technology. Lately, GSM has been catching up, but over in Europe GSM has always been around and CDMA is virtually non-existant.
Living in Ireland, I beleive that all networks are GSM, which means SIM-card based. So, you probably didn't know that there were other types of technology that weren't compatible! If anything, we here in the US are "behind the times" because we're still using an antiquated ID system as opposed to SIM cards!
HTC makes a GSM version of these devices as well, which you should consider. They are known as the Tytn and the Kaiser (our Mogul/Titan sort of comes in between, although most closely resembling the Kaiser in hardware). Next time you want to buy a phone in the US, make sure its GSM and unlocked first!
Hope this clears things up!
You should have 30 days to send back the mogul and get out of your contract. The phone will not work outside of North America. Take a look at the HTC Kaiser,its also sold as the AT&T Tilt. Its a GSM device that is very similar to the Mogul.
If you told Sprint that you were going to be going back to Ireland, I wonder why they didn't sell you the Samsung IP-830W, which works on the Sprint CDMA network in the states, but can be used on GSM/GPRS networks everyplace else.
If you can't get a full refund, maybe you can exchange the Mogul for that?
I think it's a little behind the times, but the IP830 is a pretty good phone and has a smaller slide out QWERTY keyboard.
thank you for the information , just need to find that damn receipt now and give radioshack a call , see about a swap for the tilt ,
regards
sigghhh
well it seems radioshack cant help . unless i brought it back to the store i purchased it in , and that cant really happen .
anywhoooo thanks all for the help ,
but i have just one other ,
is it possible to synq my titan with another type of phone i.e nokia 6610 and have the titan act as the handsfree ? via bluetooth?
basically like the satnavs where you have the dialer but it uses your phone to connect , seems like a strange request but this would at least allow me to use the phone features
thanks in advance

htc elf network connection problem in turkey

please can anybody help me. i bought one htc elf in dubai and i went then to turkey am trying to make it work in turkey but in vain. it is always searching for network and not finding anything.
have you tried flashing a different radio? Or, have you go into phone settings and tried to select a network manually?
i couldn't upgrade my radio version it is always arriving 79%, stopping and giving error.
Whats the error, make sure to post as much information as possible, people wold be able to help better then.
Have you checked the error codes in the ROM section?
Stu
no actually am sorry but i did not know about that section before. so it is error 270.
thanks actually i found that error solution but nothing changed still my phone is searching for network in vain. even am trying to find a network manually it is writing cannot read settings from the network try viewing settings later or disconnect data connection and try again.
where did you buy the phone from in dubai? Was it from a market etc or a store? It could be blacklisted in turkey? Just thinking that could be a possibility.
i bought from jumbo electronics in dubai it is a distributer of consumer electronics. so what can we do if it is blacklisted.
i doubt it would be blacklisted if from a shop. If it is blacklisted, theres pretty much nothing you can do about it, apart from change the imei - which may well be illegal, i know it is here in the UK.
mm is there any way to change the imei like software.
for that, i would not help. you can however search forums to see if you can find anything for it.
google checkmend as well, that tells if the phone is blacklisted etc, but maybe only for us and uk, not sure. costs $2.99 USD though.
actually there is something strange i have one sim card from UAE, when i use it the signal of network is coming and when i put any sim in Turkey no signal is coming. do you think it is blacklisted?
the turkey sim may not be registered? I wouldn't be able to say if it is blacklisted - i'm still learning these phones too
About IMEI
If you bring a cell phone from out of Turkey you need to register it in cell shop called like "Turkcell Extra".
You need your phone and your passport. The personal'll look at the dates in your passport and check the invoice date in shop after he/she will register your phone to Turkey Network. after a copule of days you can use it complately...
to my knowledge it may be because of the the frequency of the signal u r receiving in ur country. elf and elfin are triband phones.. they dont have a frequency range of 850 Mhz .. may be ur provider is giving the signal in that frequency.. try with gsm sim of other service provider may be it will help u...
thanks alot but i think my phone now is blacklisted cause as i remember i came to turkey before long time and it was working but now it is not anymore even i tried different sim cards like vodafone and turkcell but in vain. i have other phone am using now and i registered it on my passport it is working but i want to use my elf actually i dont wanna use other phone cause i love that phone that is all.
first unlock your device, then install the newest radio.

No signal Tmous HD2

Please help me fix my beloved HD2 I have replaced my HD2 with one I purchased off ebay a few weeks ago, as the hardware on my old one failed. Anyway, it turns out that the one I purchased off ebay is a TMOUS HD2. Anyhow, the phone works perfectly in every operation, except the most vital feature, cellular connection!
On the original Windows Mobile 6.5 rom, I just get an exclamation mark where the signal should be. When I search manually on network selection I can only see Orange that comes up. This is no use to me as I am on GiffGaff (ran on the O2 network).
On android, under the status screen I can see that there is signal being recieved, but most of the other boxes say things like provider unknown etc. The signal says something like 103db, -3asu (these are only the figures I remember), so I can see that some signal is working.
On windows phone it says No Service on the phone icon. I have tried the APN tool and it still does not work
What could this be? I have reflashed some different radios and it still does not work. The simcard worked perfectly with my previous european HD2. I have now spent about 8 hours tonight trying to get it working ;(
Many thanks

run htc connection setup obtained from the htc marketplace part of the windows phone marketplace. those numbers you see under android is the signal strength numbers. did you not know you were buying a tmous phone from ebay and not the european version? the phone should still work as the hd2 is a quad band phone.
anyway, the connection setup app is what you need. make sure your cellular connection is on in settings.

hey man, cheers for the reply! I thought that it was a european phone, the pictures showed a generic HD2 with white buttons, so they must have just used a stock picture, I was quite happy that it was a tmous one, because of the extra ROM. Anyhow, in windows phone 7 I did actually run the HTC connection setup, and configure it to giffgaff, but I still cannot call people as it says there is no service :/ I have reinstalled android and the signal strength is -95dBm and 0asu, is that a bad signal?

try locking the radio to 2G GSM in settings & see if you can get on the GiffGaff network.
Try some other sims to help eliminate a network issue.

I have enabled 2G in the android preferences on the typhoon rom, I have also inserted a different simcard (BT) and the same issue occurs
Could it be a radio issue? I have my suspicions that this is a refurb phone, could the antennas not be touching the chassis properly?

Sounds odd, try a WM6.5 rom such as NRG & one of the top radios such as linked in my sig & see if you get it working then move on to ROM of your choice or pin it down to hardware issue ...
I have a TMOUS HD2 & have used it fine on Orange, Vodafone in the UK. If issue persists on WM6.5 I would suspect hardware issue !

Hey, cheers for trying to help!
I installed the stock WM6.5 rom and suddenly I got 5 texts and there were 4 bars of signal. A minute later all signal was gone and no matter how hard I tried I could not get any
This was after I opened up the phone and made some fixes.
It turns out the phone is a refurb unit that the seller was trying to sell as brand new! I was first alerted to this when I saw the original sticker seal was replaced with a Chinese one, and the grill near the earpiece had dirt in it. Most of the antenna prongs on the mainboard were bent down, so I bent them back up. All of the screws that were meant to be securing the main board down were also missing. This is a word of warning to those buying off ebay. The company I bought this off were a very large Chinese company, but it would appear that they refurbish phones, make them look new and try to sell them as new, and most of them work. The link to the seller is below:
http://myworld.ebay.co.uk/cellphoneforever
Do not buy from them!
Thanks for everyones help with this, I have given up trying to fix this piece of ****, anyone have any ideas what I can do with two broken HD2's? Any buyers?

[Q] Not registered on network

Hi there!
I bought a Galaxy Note III in Thailand, unlocked, and I am trying to use it in India, Vodafone. Data is working perfectly but when I try to register it on network is not possible. I already went to the company and replaced the sim card. Same problem. When I was in Thailand it worked perfectly, even I tried in Nepal and it was working 100% too, so phone is ok. Somewhere I read there is a new system to avoid bringing phones form one country to another. Some help would be apreciate. Thanks in advance. Be happy

maybe you should try another network sim card or go into the settings and search for networks and then hit automatic
Then maybe you both need to flash your own regions rom?
Check your imei number, does it different from under the battery? Your phone probably been injected with superimei which did not work with gsm mode (it work in wcdma). You need to find a repair shop which has the SPT BOX to repair your gsm connection.

I am facing a network problem when i use gsm network it works fine but when i chane it into wcdma it says no service plz register when i tried yo search no networks appears plz give me somee idea samsung galaxy note3

GT-I9515 2G only - unable to register to 3G/4G network (Germany)

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:
