I just bought a second Siemens SX56. It was supposed to be in perfect working condition but it won't acknowledge the charger and the batter will not charge...it doesn't know it has been pluged into external power. The ree/yellow/green power button is off completely....
ANY IDEAS BESIDES THROUGING IT IN THE TRASH???
Moved topic in the correct forum.....
I think there are 2 possibilities:
1.) The fuse of the device is broken
2.) The Radio Stack is malfunction
Stefan
Dan, please dont throw it away even though it may appear useless. You could first try jumpering the fuse link which means disassembling the phone, if it is the gsm side thats gone then I dont have a solution. If you decide to scrap it there are people on here that will buy parts such as the lcd/touchscreen, the case and the accessories so it isnt a total loss to you.
mine stopped charging too. coincidental with losing signal in a bad reception area. i am in Vermont where reception is now allegedly available (my kids nokia 3226 can get two bars and make calls in certain spots). i lost signal on the way up the mountain but the coverage here is really bad anyway. are these events related? the led won't go on at all, i have left it plugged in with the dongle direcly into the power supply but nothing happens and the battery keeps draining. i just need to jumper a fuse link? where exactly is it? thanks!!!
TIA!
it appears that this problem is not so uncommon. i saw the threads that show how to replace the fusible link or fuse at F0...
update: false alarm - turns out several of the outlets in this place where we are vacationing are not wired properly! my xda livesz on duh...
[Fix] I accidentally messed up my signal by pushing the little button on the lower right side of the battery. don't do this I could only achieve EDGE after, if that. so what I did is use a 4 inch copper wire and electrical tape. place one end of the copper wire in the little hole(it's a part of the antenna receiver group) and use a thin piece of electrical tape to tape it up the back side by the battery. now I have a better signal then before. I recommend not doing this if your signal is still working. Do not me if you mess it up, this should only be a fix if you need it.

Very interesting. Didn't know that. Don't worry, I won't try it.
lol, thanks now we knoe that we don't have to mess with that little hole....
could u upload some pictures???
Pics
Here are some pics. the red circle is the hole will the antenna receiver in it, in which i have inserted the copper wire. The orange line is an illustration of the copper wire and the green circle is the actual copper wire. you can see where i very shoddily taped it XD

Dudeeeeeeeeeee! I got this very late. Last week my phone went off without notice at all, so, trying to make it come back I pressed this litle thing thinking it was a kind of hardware reset switch... Anyways, my cell came to live after 3 days, at least accepting my ON command and showing low battery (this is another issue) but now the signal reception is real poor (only 2 bars -105 dBm 4 asu) and yes...now I know that I have screwed it... Let me try your approach with the cooper wire.
Thanks
Guys be VERY CAREFULL as that to me looks like a port for an external aerial. if you short the iner pin with the outer sheild you could do some real damage to your phones transmiters/recevers
Also another thing to take into consideration is that aerial are a certain length to what freqs they work at
ie the FM areial in your car is shorter than the AM aerial, and the digital one is shorter again.
There is so much theory behind aerials that it is not funny! (im a comms tech by trade)
Just PLEASE be carefull guys!
Pvy.

So did this help you or not? Screenshots?
Guys I am having the same problem of low signal at various locations. Pls do let me know if it is advisable for putting a jumper of copper wire as described.
Do I need to solder it with the hole ?
Will I loose my network permanently ?
Up to you
I would advise trying a different carrier or ask someone with the same phone/carrier how their signal is. I would only use these methods for emergencies like my situation, or like the other where he had next to no signal where he lived. As for soldering, i never thought of it, i revised my method, which i should post screen shots, by placing a larger wire in the hole and using a glue gun to hold it in place. I take no responsibility for antenna loss, because once you shove something in there, you won't have a signal unless something is in there. Good luck, i hope you figure out what's best for you and don't forget to post your results =D

Thx.. but same situation as yours the signal keeps fluctuationg n sometimes no signal so its kind no-no use sometimes or bad signal.
So I was thinking of putting a copper wire as suggested and checking it out.
As you mentioned like in near future if the wire breaks or think of removing it, I wont be able to get any signal in furture ..
Do you suggest replacing the antena & what would be its cost ?

Send it in, if it's under warranty . If it's just an old phone you have, and you still want to use it, by all means ty it out, i guarantee a better signal as long as you use a long enough wire. When i switched to a thicker one, i got a better signal, but the battery cover doesn't close all the way, but that doesn't matter since i use a case and i don't notice it.

Hi,
I've been having a somewhat mysterious problem with the wireless internet (Wi-Fi) signal on my SCH-1545, hopefully someone here can help me find a solution.
Details:
At rest, my wi-fi signal is weak, regardless of which network or router is producing the signal.
I use an oversized Anker 7800mAh battery, which adds a considerable amount of weight and bulk to my GS4.
I am currently running a recent snapshot release of Cyanogenmod (11-20140804-SNAPSHOT-M9-jflte). The last time I updated was few weeks ago, but my wifi issue began sometime early this week. Thus, it seems unlikely that the ROM is to blame. For what it's worth, my baseband version is 1545VRUAMDK.
Oddly, after some poking around, I've discovered that applying pressure to the back of the phone near the lock button seems to increase the quality of my wifi connection. For example, at rest right now my phone shows a 30% signal; when squeezed in the aforementioned manner, the signal jump s immediately to 55-60%.
I suspect that there may be some fault with the wifi antenna connector, or with the antenna itself.
My best theory right now is that a mishap or fall with this bulky battery installed may have delivered a shock to the phone's hardware beyond what it is designed to withstand. Consequently, it seems that the wifi system was somehow compromised. I've tried cleaning the wifi contacts as suggested here[1] .
Has anyone had this problem? Can anyone offer a solution?
I can't go on using my phone like this, and to get a replacement will be quite costly. However, if I do end up getting a replacement, I have my eyes on a LG G3
Thanks for your help!

Have your tried doing a factory reset? I know this is a pain in the butt but maybe it will put your mind at ease. Have you dropped the phone or anything that would cause the antenna to suddenly become loose? Is your connection bouncing up and down or is it consistenly just staying low? Also before a factory reset try getting Wifi Analyzer from the app store and check to see whats going on. Just sounds rather buggy that it suddenly started happening.
Same thing been happening to mine just recently. Seems like when I squeeze the battery cover the wifi signal is stronger for a limited amount of time.

If you squeeze your phone and it affects signals take off battery cover and try tightning all the little screws around the phone with the battery out.. might help just saying
Thanks for your suggestions folks, but I still seem to be in a pickle.

I tried a factory reset, didn't seem to help according to Wifi Analyzer (thanks for the app suggestion). As I said in my original post, I fear that drop may have caused this problem: since I use a heavy extended battery, I expect the damage caused by any fall would be magnified.

I attempted this as well - I removed the back cover and ensured all the ribbon cables and antenna cables were making a firm connection, and then I tightened all the cover screws. Nothing seems to have helped. Concurrent with my previous statement, I fear one of the modules (specifically the wifi/bluetooth SIC) on the motherboard may have become slightly dislodged from a random fall.
Does anyone know of a way I can test this theory or get it fixed if such is the case?

i'm in the same boat, my phone is exeriencing the exact same issue. I've got a new back plate on order, hopefully replacing that and the wifi/bluetooth antenna will resolve it.
have you had any success since this post?
The wifi signal strength is normal and good before, and it becomes worse about one month before, the wifi signal strength becomes weak, I have tested with other phones. At the beginning, I think it is the problem of the MIUI, then I flash Cm14.1 to see, but the wifi signal strength still the same. Can anyone suggest any method?
how exactly did you measure wifi strength?
and what can possibly go wrong with weaken wifi signal?
care to explain?????

I have already fixed the wifi problem with opening the case of the phone and put a soft metal clip between the two wifi contacting points and the antenna.
I think it is the problem of the aging of the the two wifi contacting points .

I did some search on the internet first, finding out that many ppl having the same problems due to the reasons of falling down the phone on ground.
It is easy, First open the case, then open the upper part which is with 4 screws. then remove it and you can see there is two contacting point on the upper right side.
They are are the contacting point for wifi.
Just use some soft clip to increase the contact area and install back the upper part. that's all

i hope you already solved the problem, but if not, try this out, it work for me at least now my redmi note 3 wifi keep connect and the signal increase, first open your phone back cover (you can use thick material such as guitar pick) then at the top remove 4 screws (one screw is hidden in the back of small mi sticker) then remove the black small cover, there at two contact point put something (for me i use aluminium foil, i take it from coaxial antena cable, cut small square or so put in there) that's it put it back, try to test it first before you put the cover back because a little bit hard to open the cover though. goodluck....

This works in Xiaomi Redmi 3S? I am with the same problem, but i am not sure how to open it and where are the part that i must put something in that two contact point.
This is a very weird issue. I had very good wifi strength before and with the miui updates the signal is very weak now. Redmi 2 and any other phone has better signal.
I have the same router than before.
But its strange that other ROM also has weak signal... Because redmi note 3 pro used to be considered a phone with wifi signal strength
I have my phone suddenly got low wifi signal. I try your suggestion, and it works. Wifi signal is as good as new phone.
I do both put paper under the pin to leverage the connection point, AND put aluminum foil to the contact point in the small black cover to increase the contact area. Not sure which action do the magic

i need to try
As the title goes I tried to make a GPS fix buy adding a little thin plastic under the pins showed in the video tutorial I used but after assembling back the phone noticed that I cannot connect to 2G anymore. I switch to 4G and 3G with full coverage but when I try to went back on 2G the network signal drops and phone says "Emergency calls only". I opened it again and removed the plastic board and switched it on and got slmost perfect 2G coverage but my microphone stopped working - nobody was able to hear me speaking so I opened it again and added a little card board piece on the place and now I have good mic with good 4G/3G signal but again with no 2G signal again. Can somebody tell me what I'm doing wrong ? Also where are the exact places of the 2G/3G/4G/GPS antenas ? I travel a lot on places with low 4G and even low 3G coverage so I really need the 2G mode again. Please help me fix it as it was before. I need 2G more than GPS so if somebody tell me how to reverse this would really appreciate it, thank you !

Ima follow this one closely. Mine has the very same issues ive bassicly asked the same thing
Mine does it one all three. Rarely picks up 2g gsm network gets crappy 3g and lte. I use lte discovery to verify all this. Now i have noticed that if i pinch the chin or hold the phone like laying in bed only by the chin i get killer signal and even pick up 2g at the same time as lte.
I watched other devices all get band 5 lte and gsm at the same time.
I cant find any confirmation on where the antennes are even located in this device.
Today I noticed that my sim tray stays slightly out of the phone body so I tried to push it in and it wasn't going any furder as before. So I though there must be something in the tray preventing it to push in till the end and I used a magnifyer to see inside and noticed a small plastic that seemed from the same material of the pick I used to open the phone so I got it out and now the sim tray is closing nice again and now I'm able to connect to 2G but still the reception is not good as it was and it drops from time to time... Still this is an advance in the right direction. I think I had broken or bent or moved something slightly off place from these several interventions so I'm f****d up.
Please guys don't try to make any gps fixes because you will do more harm than good ! That is my advice !
If still somebody can help me, please write ! Thank you !

Nobody here is engineer at LG. And nobody here has any real solution for GPS / 2G / 3G fix. Looks like GPS breaks again even after sending it to repair. This LG G5 has been the crappiest phone I ever bought. I'll be buying a G6 soon.

The 3pins in the video are for the Volume buttons. The REAL GPS antenna are the ones next to the headphone jack.
So far I experimented that the cell antennas lies at the top of the phone since covering the top-middle section of the phone Cell signal drops.
Maybe the plastic shim you put in is too thick that it's interfere with other internal components, like the black RF antenna ribbon that runs across the top section of the G5. See if removing the plastic piece resolves the problem
Hi guys,
Just want to let you know that I gave the phone to a service and they found out that I broke some of the pins even without noticing. That is why this problem occured! They were able to replace them so now my phone is live and kicking again with full network coverage on all bands (2g,3g,4g). So happy with it ! So go ahead and bring your phones to a repair service center and make sure it will be a good one! First I went to affiliate LG service and they told me that most of the things are unrepairable and will have to change the whole motherboard which costs as a new phone so I lost any hope fixing it but later a friend of mine recommended another service where the guy told me he will inspect all the parts of the phone and will call me if he finds anything suspicious or broken. So I left the phone and after 2 days he called back and told me that 4 pins were broken and 2 more damaged and bent badly. He also told me he thinks that if we change them the problem should be solved so I agreed and he did fantastic work on the phone and now works as new !
So don't be disappointed and find a good service where they can try to help you. Also when you are doing some mods to your phones please be very careful!! I confess that I wasn't careful while doing the mod - I was at work and even didn't had the necessary tools for the task, also the colleagues were around and distracting me so I wasn't able to focus entirely on the task and did more harm than good! Good luck !
Thread may be closed, problem solved !
