Hello, recently I got used e10i (very cheap), everything works except gsm signal.
I see, that there are missing some parts, so my question is - how hard would it be to fix antenna problem, and where can I get parts?
i think, that it is really difficult operation. It could cost about 30-50€ in service.
@ tom2910 - stop that bull.hit if you don't know what you're talking about ......

Hello all, i have a Vibrant. but unfortunately in my area at&t only operates their 3g on the 850band, which the vibrant doesn't support. so ive been stuck on Edge for months now, and getting sick of it.
I was wondering if the internal cellular antenna could be swapped with lets say a samsung captivate. so that it could operate on my local 3g band? (without any horrible software issues).
thanks for replies.
I don't know if this is actually possible, but I wish it was. That way, I would my antenna with the one in the Galaxy S 4G. I guess you'd have to find someone with that type of experience.
As of now im guessing it isn't, been searching everywhere on the net and i dont think its even been attempted on any android phones, I have learned that the cellular antenna housing is in the hump on the bottom of the phone. may disassemble it and take a look.
EDIT::: this is completely possible, however, i cannot find a supplier or place to buy a compatible chip that works on all bands....
ANYONE lemme know where i can. please and thankyou
Hi guys,
First post so please bear with me...
The phone was dropped recently and screen smashed up badly.
Replaced screen and thought all was working fine until tried to make a call/send a message when I discovered that the phone had no network access...
Here's the diagnostic process I've been through...
Wifi works100%
Sim works in other phones
Other sims don't work in this phone.
Checked the antenna assembly to ensure contacts okay
Sim definitely reading - able to read sim contacts
Switched to airplane mode, reboot, turn back on - no luck
Searched for networks manually - no networks found at all. Another phone (samsung galaxy gio) finds all three (Optus, telstra, Vodafone)
No networks detected automatically either
No network detected using 2g only
So, if my wifi is working fine, that should rule out an antenna issue which to me indicates a hardware fault with the network side of things...
Is there a way to verify this is actually the case? And if so, is there a way to repair/solve it without doing a motherboard replacement???
Here was I thinking that it would be a cheap, easy repair... :/

If you want it free of cost so first try flashing new firmware via odin and then check it if not then give it to service centre !:good:
Make sure you're using a stock rom just in case it is a software problem, but it looks like a hardware problem to me. I recommend taking it back to the repair centre where you got your screen replaced.
I don't think it is possible without a motherboard replacement.

I think I'll do a total strip down again just to make doubly sure that i've got absolutely everything connected in the right place and then if it's still not resolved, I'll look at sourcing a motherboard through some chinese friends...
The phone was actually purchased when in china, and as a result I had to flash it with an Aussie rom to get the google back in android. It's all worked fine since then until dropped which makes me think it's hardware related. problem with buying it in China is that I can't seem to find a motherboard online for it galaxy ace 5830i (the 'i' is the problem... can find plenty of 5830 mobos but seems the consensus is using a 5830 mobo will brick the phone...)
Oh well, thanks for the advice guys.
Even i had the same problem, but i solved it by flashing a stock ROM. You can try that or flash a stok kernel
recently I also had this same problem, even installing the stock rom did not solve, so I researched in several places and saw what could be problem with the IMEI, I did the whole process of repair IMEI and my phone is back to normal , try this method:

So...
I pulled it apart again to double check everything and noticed that the cell chip had come disconnected from the mobo upon impact and was only attached by three copper strips. After staring at it under a bright light for a while (no magnifying glass was to be found!), we stuck some super glue under it and tried to dry contact all the points... but it still didn't work.
However... after talking with a mate who's into circuit boards, he suggested that I try putting the mobo in the oven at 350 deg for 15 min to resolder all the joints as they use low-temp solder on these sort of boards.
I've got nothing to lose, so will be giving this a try when I get a chance and see if this brings it back!
I'll post back my results.
Yeah, and I recommend using a fine tip on your soldering iron just to be safe.

Hi All,
I'm new here. Hoping someone can give me some advice/direction on my issue.
Just received two Elephone P3000S phones (one for me, one for gift). I'm in Canada on Koodo network, but don't get 4G because we are pretty rural (west of Ottawa), so we are using WCDMA/HSPA+ 850/1900 MHz.
The P3000S supports the following:
GSM:850/900/1800/1900, WCDMA:850/900/1900/2100(HSDPA), FDD-LTE:800/1800/2100/2600
At home, on our old phones (Samsung Galaxy SIIX), we would get cell signals of -93 dBm or better (not great, but usable). With the P3000S phones in the same location (both of them), the signal is -110 dBm or worse (not usable - not able to make calls or send texts). There are no protective cases on the phones to interfere with signal.
I've tried the the following:
- choosing 3G only and WCDMA only networks and editng APN settings specifically for Koodo
- changing/adding build.prop entries for ro.ril
- posting in Elephone forums - no help
- contacting Elephone - no response
The P3000S is new - just came available mid-December. Elephone has issued one update since then. It did not help my signal problem.
I know this could be a hardware/antenna issue, but since the phone is new, opening it up to tweak/boost the antenna is not really an option - a last resort if I can't sell the phones to someone who is located where they will work.
So, my next step (I think), is to try flashing a new modem, but I have no idea where to start with that to find one that might be compatible with Koodo and the P3000S. I'm willing to try several, but it's very new to me.
Relevant info:
Octacore MTK6592 + MTK6290
Android version: 4.4.2
Baseband: MOLY.LR9.W1423.MD.LWTG.MP.V3.P3
I'd really appreciate any advice.
Thanks in advance.
Anyone have any ideas where I might start?

Hello, i bought same phone and seems signal is ok. But i am probably not so far from BTS.
It seems your phones has worse antena then phone before, you can not solve this by software (ril mod, baseband etc.). You have to try to solve it by hardware mod, probably extend antena to get higher gain. Under and around NFC antena on back cover is enought space tu use copper foil strips, you can try make unclosed frame with connection on main antena.
Hi MioCZ,
Thanks for your thoughts. So you don't think a different region (i.e. North America) baseband/modem would help at all? The hardware tweak is my last resort - I'm not particularly fond of opening up a new device. And I don't exactly know what to look for as far as NFC antenna or main antenna. Any idea where these are located on this phone?
Again - thanks for your insight.
EDIT: Oh, I see you reference the antenna on the back cover as the NFC antenna. I can try to work with something there without opening up the phone? Or do I need to make a mod to connect the new copper to the main antenna from there? So I guess I need to know where the main antenna is. Is the 4G/LTE antenna the same one used for 3G/WCDMA/UMTS/HSPA? I'm not sure if there are separate ones. If so, the 4G/LTE antenna location is pretty clearly marked.
EDIT AGAIN: I answered my own question by reading up on cell phone antennas. Gotta love Google. So, I'm going to try to rig something up to the main antenna, which I assume is under the section marked "LTE 4G" in the upper right hand corner (when looking at the back of the phone). I'll post my results when I finish.
Engineering mode
You can call *#*#3646633#*# to enter to Engineering mode. It should have antenna test somewhere in menus.

Hi, have you solved the issues on your phone?
I believe this is the same problem that I am facing with coloros. In fact he does not write the correct base band and when he writes, does not connect to the network 3G / 4G or make calls. is a mistake that just found this unit ... which makes the port of ROMs for this device and portability including future versions of android. It is not compatible with any other MTK6592 I know.

No, nothing I have tried helped.
Hey XDA,
some month ago I damaged my phone after 3 great years with it.
I bought a new one via ebay and here is the problem. He said for sure its all fine with it. There should be no problem for sure.
First I had somehow reception issues. Sometimes the connection to my provider was off and sometimes it had 3 of 4 Bars. People told me its not a flashable modem issue, but a issue where i have to change some hardware.
so did I, changed the antenna and the receiver and still nothing changed.
I always want to find and fix the problem by myself, but now i'm at some point where i really dont know what else i could do instead giving it to a repair service.
what i did? changed all modems and stockroms which I could get from the internet and install them one after another and checked my connection via "Network Signal"
the biggest issue there was, at home the connection to my provider was good and at my girlfriends home it was totally broken.
maybe anyone could help me out there?
i just read http://forum.xda-developers.com/showthread.php?t=1667326 maybe i should change the back plate where most of the stuff have connectors? like the GPS does? because if i dont have it on i wont be able to connect anywhere.
My Provider? Vodafone D2 and in other Cellphones the SIM-Card doenst have any problems with the connection/reception
Hello! I want to start by telling my english is not the best so i will do my best.
I have an s6 edge 925f that is around 1.5 years old. The battery is really bad so i watched a change battery movie on Youtube, ordered new battery. Got the battery and started to open up my phone.
Everything whent well some things was hard to figure out but nothing was broken and new battery is in. I started the phone and tested functions to confirm everything was ok. So i thought everything was ok until i was going away from home and my wifi was away. Now i noticed i got none signal from gsm.
Checked my sim card and controlled all settings and nothing helped. Opened the phone again and could not find anything wrong. So how can i continue my troubleshooting? Where is the antenna and what could got broken?
Another wierd thing is when i was drivning into another village my LTE signal found network so i thought everything was fine so i drove home. When i got outside LTE area the gsm was totally off again.
Any ideas whats happening with my phone?
Best regards Christian.
Anyone?
I have the same issue. I checked everyhting and all is well connected. Sometimes it will take LTE/4G signal but the phone gets very hot. If I leave it to GSM only I do not have any problem. Temperature is normal etc.
I have same issue with my phone and i think it is GSM unlock or faulty GSM IC because i purchased it second hand from somebody
Somebody told me i can fix this issue for you just by software modifying but i didnt trust him, have you checked your IMEI is real by checking in imei.info
The IMEI is real. The location of the antenna is in the midframe? Maybe a bad connection of some kind.
