A few months back my Legend went through a cycle in the washing machine. Afterwards I did all the recommended things (take everything apart, leave it in the sun for a day or two, keep it in a jar of water absorbent silica in the evening). Anyway, after three or four days of that, I put it back together again and my battery was dead. Tested it with someone else's battery, and everything worked perfectly, I even made a call with it.
I then waited about 3 months for a new battery (it got stuck at customs) which I finally go this week. Thing is, I now have 0 connectivity with the phone no matter what I do. I always have 0 bars, I can't connect to wireless networks (even though I pick them up perfectly), and I can't get the GPS to turn on at all. Everything else works fine (including the FM radio), but there's no connectivity.
I was hoping it might be a software issue of some strange sort, since the wireless picks up well but just says "connecting--disconnected" when I try to connect. A hard reset did nothing to the phone though.
Is there anything else for me to try? I'm running pretty thin on ideas at the moment. Would replacing the back cover fix any of the connectivity issues? Also, is it still possible for it to be a software problem, and should I maybe try to install a custom rom on it?
Any advice at the moment would be much appreciated. Thanks!
EDIT: I just realised that I had made things worse with my reset. Now I have no file browser with which to sideload apps and no internet connectivity. EDIT2: Managed to fix the file manager problem with ADB. Now just the actual problem again
The GSM antenna is in the bottom part that covers the battery compartment - I'd say you have some oxide on those two contacts.
Take a small screwdriver (or a needle) and gently scrub those pins on your phone.
As for the two on the cover, you'll notice those two parts come apart, so I'd take the inner part and gently brush the two contacts with a piece of cloth and a toothpaste - it's a good thing to gently brush something.
If that fails and you're sure you plugged all inside as it was...it could be another problem...
You may also try bending the two contact in the phone out - these act like a spring, but be gentle about it
P.S.: Is your Legend at least clean now?
EDIT: Now that I think about it, you can try the phone with piece of wire:
cut a wire of : speed of light/frequency in Hz and connect it to the two pins inside the phone
For USA:
299 792 458 m/s divided 1 900 000 000 Hz = 0,15778 m
Thanks Dr.Romca.
I'm trying the clearning out for now. when you say the battery cover comes apart, are you talking about the piece of plastic inside the rubber? There seems to be an additional piece of plastic inside the rubber which might come loose, but I'm not quite sure how to pry it out without breaking it. Any tips on how to do this?
I'll give the piece of wire a skip until the very end
It's not glued or anything, just push the rubber part in the middle and try to click it out...

Ahh ok, I wasn't sure what to expect on the other side. Didn't want to jam a screwdriver in between the plastic and rubber and hurt some electronic component. Managed to get it loose though, and gave it a thorough but gentle rub down.
EDIT: Nope, still no service on it. I still find it strange that it doesn't want to connect to the GPS or the wireless either. As far as I know, those shouldn't be affected by an antenna issue right?
That's strange... WiFi and GPS antenna is in the other rubber part....
It seems there might be something wrong with the PCB...
I'm at a loss here...
Damn I have connectivity issues here...
The strange thing is it worked once after the washing...
If you have the courage for it, you can also try this:
Take the phone apart, I mean really apart, if you can unmount the display/touchscreen. Then take the PCB - mainboard, try to put a sticker over a microphone and the repro, then take a toothbrust and a detergent and brush the PCB - make sure you clean all, there will probably be some metal plates that look they can be unmounted, so try to unmount them and clean beneath them.
After this take the PCB and put it in the hot-air oven (if you have one - NOT a Microwave! ) 40 - 50 °C for like an hour should do the trick...
You can also use alcohol to clean the PCB, but since it was water that caused this, I'm gonna presume you'll have more luck dissolving with water again...
Anyway, that's what I'd do, but I'm and engineer, so if you're not sure, just take the phone to service
Hello,
The WiFi and gsm signal are at seperate places on your phone, so you either got a major problem with the hardware, or the ROM just went nuts. I suggest you flash a new ROM before you take the phone apart, cause it might get damaged irriversably..
Goodluck, keep us updated!

Thanks for the continuing advice. You're right about the engineer thing though; since I'm not an engineer I'll leave taking the phone apart until the very end.
I've never flashed a ROM before, but I'm sure I'll be able to figure that out. What initially made me think that the ROM might have gone crazy is the fact that the wireless actually picks up networks. The further I get from a network, the worse the signal, and the closer I get the better, so the wireless signal is working properly. It just seems to have a problem connecting, which seems like a software issue rather than a hardware issue.
If that fails, I'll send it to HTC and see if they can do a repair for me. I already sent it to them for a check-up and a new battery directly after I had it dried out. I included explicit instructions that it got water damaged, that I was not looking for a warranty repair, and I would just like them to make sure everything is working and bill me for the repairs and a battery. Two weeks later I get the phone back with a note saying that they noticed some water damage, and they don't do warranty repairs on water damaged phones Anyway, I'll try them again.
If HTC fail to do anything again, I'll try my luck with a full teardown. Still, ROM flash first.
EDIT: Ok, so I followed this (http://forum.xda-developers.com/showthread.php?t=894465) post up until the end of downgrading your rom, and the problems are exactly the same. From my understanding, this would have installed a clean rom onto the phone, so any software issues should have been cleared up. I'll still try and install a custom ROM, just because I've always wanted to and just maybe something will work, but the software problem seems an unlikely explanation now.
This is getting very strange now. Using my newfound "Wi-Fi" Hotspot powers, I can actually create a Wi-Fi hotspot that my computer successfully connects to. Once again, if the hardware was broken I don't see how this could work. I still can't connect from my phone to any Wi-Fi network though.
As I mention (for a completely unrelated reason) earlier, I sent the phone in to HTC. This might be a very dumb question, but is it at all possible that the ROM on my phone works at a different wavelength/frequency than what is used by carriers in South Africa (where I'm from)? I'm thinking maybe HTC did a stock reset or something which changed it, because I never tested my phone after getting it back from them. That would also explain why my phone doesn't have reception with the current ROM. Just note that I have no idea how these things work, it's a complete shot in the dark
EDIT: My GPS also works now, or at least the gps indicator flashes when it should. Since I don't have any kind of internet access, I have no way of knowing if the GPS works, but in the past it never flashed.
I'm currently thinking of using my computer's wireless to connect to my phone, and then bridging that connection with my UTP connection to connect to the internet. I have no idea if this will work or what exactly if it will get me closer to a real solution, but at least having internet access on my phone will make things a bit easier. Will let you know how it goes.
So have you succesfully flashed a different ROM?I'm not sure what type of rom should you have but WWE by it's definition should work...So if you have rooted, try any WWE ROM...

I first downgraded it to 1.31, and now it's on BlaYo's B0.2.
can you check what radio you are using?
You may want to update it!
It's in settings / about phone / software / baseband version
My is 47.51.32.17U7.13.35.05
Not sure if there's a special version for SA, but here is a radio update only:
http://forum.xda-developers.com/showthread.php?t=706435
Sorry for the late reply. Real life caught up for a day or two.
My baseband version was 47.26.35.04u_7.05.35.26L. I updated it with the radio update you posted, and it's still not working. As far as I know, South Africa can use any American phone except those on Sprint, if that helps at all.
Also, I was away from home for the last week, and now that I'm back home my phone connects perfectly to the wi-fi here. I am certain that I did not make any mistake in connecting to the other networks I tried, as I tested the settings on multiple computers and entered the passwords multiple times, but the wi-fi seems to have been a red herring. So the only problem left now is normal phone connectivity.
I'm sorry to hear that...I'm not sure what the L means at the end...but about the wifi thing, it has been mentioned here that different locations use different WiFi channels...so at this point it's almost sure you have a driver/settings mismatch somewhere...
but I don't know much about that...sorry..
I Just got my phone back form service (witch was dislaimed as I hadddent removed the Bootload) But anyway, the problem is that i cant find any signal, im not sure when it happened, but maybe back when i was messing with som WinMo 7 installation. Now im back on the latest win65 offcial rom. but still no signal.. ANy ideas?
Should i reflash my radio rom, and if so - how do i do so?
Kind Regards. Johnsen

I'd try a new radio. Just download any of the radios in the below link, the ones that end in .50 and are 2.08.50.xx and above are safe for ANY HD2, (all others will brick your phone if you have a tmobile usa phone) just download it, unzip it, get an activesync connection, and run the RUU
http://forum.xda-developers.com/showthread.php?t=611787
I live in maryland here in the U.S. and I've found 2.08 better then 2.15 which is a newer radio so you'll need to just try a few out and see your results.
For a good way to get an accurate reading on signal I would go into settings, about phone then network. Look at the signal you have, I would suggest to leave your phone in one place and don't try to move it. Get the readings maybe 3-5 times over a few mins. Then flash a new radio. The closer to a positive number the better. Low signal for me normally means -108 or so. That's normal to have it negative when you have poor signal. Good (in my apt) for me is about 89 or so. This is a little more accurate I feel then trying to see how bars you have. Infact one radio over another may only show a small increase and not enough to generate a full bar so just play around a bit to see what works best for where you live.

Thx for the suggestion, I found that flashing new Radio was the propper easy. Anyway - It didnt do the trick. Tryed several roms from the list but with no luck. Still no Signal. Any Ideas?
Okay im standing between two choises now. (Since no warrenty is covering this if it should be a hardware issue)
1. Im having hope to fix this somehow - I just have no idea how but if its software related ther must be a way.
2. Getting a new phone, since this the repair of this could cost me alot, in wich case im more into just getting another smartphone..
EDIT: I have a theory - but im not too good with that stuff - since hte signal is so low and only is able to find a tiny bit of signal where the signal uused to bee maxed out, that the inner antenna has come loose?
If you call T-mobile and explain the issue they can do two things for you.
1st.) they can see if other people have complained before and if they are currently working on a fix. A lot of times this could include repositioning the tower slightly to grab a signal better for your area. Atleast this is what I was told when i called.
2nd.) they can update the signal on your phone using a mmi code. This is a code like *#773#* ????? i really dont know what the code is but thats what they will probably do with you on the phone when you call. This fix didn't work for me but it was something the technical support people wanted to try, they did say most of the time it doesn't seem to fix the issue but for some it does.
If you have Android on your HD2 and your still having problems and its getting to the point you cant even use your phone I would try and go back to winmo. I have noticed a signal drop from going to Android and have thoroughly tested this with several different phones including two different HD2's. I can say that winmo does "seem" to provide a better signal then Android, although it is small, its still enough to notice and give far less dropped called (for me). Other things to worry about is construction and interference. Concrete and many other materials that homes/apts are made of can cause interference. Also electical interference is most common so you should not place your phone by router, computer etc..as it could be the source of the problem. As for me this does not effect my signal.
Here is a link to something that could fix your issue BUT please know that this can cause your phone to become worse then it is now. It does have to do directly with what your theory is. My theory of how this could work is if you have dropped your phone which a lot of us have done. When you drop your phone it knocks the circuit board inside around causing the connectors to possibly become unaligned. I would advise you to EXHAUST ALL OTHER MEANS BEFORE DOING THIS. Some people have reported they did see a huge fix by doing this while one person broke the antenna contacts on his phone. So please be aware of the dangers.
Thanks, i dont have t-mobile as I live in nothern europe. And Anyone refuse to service my phone as I forgot to remove some software wich void the warranty.
Anyway, im pretty sure its from dropping the phone evry now and then, im just gonna get myself a T5 and try have a look on the hardware part. If that doesnt look broken - im gonna try going back to the software part. But thanks alot for tryin to help me out.
And this is to anyone ells, heres is as vid on how to tear it appart:

I recently got the courage to unlock and root, but I feel like a bull in a china closet. I just breaking things and fixing them! I really feel like a dumb animal, but I keep reading and learning. So far, I've been able to fix or reflash until this post.
My issue is my when placing phone into car dock, I can't hear a call afterwards. It doesn't matter if I leave the phone in or take it out, I can call out, but the person I"m calling can't hear me. The only cure is a reboot, in which calling can resume until I enter the car dock.
A little background, I have flashed several ROM's over the past several days and I'm not sure where it started. PacMan, DeadCalm, etc. Now I'm using 4.2 RootBox. During my flashing spree, I did have almost the same issue, but minus the car dock. I think it was with PacMan, after every call I would lose the ability to hear or talk on the next call until a reboot. Again, now is good, except for when I use the car dock.
I also flashed Arrghs, 19 kernel with DeadCalm to fix the known screen proximity issue and borked my phone. I got a bootloop I couldn't get out of and had to use recovery.
Does this make any sense? Before every flash, I'm wiping numerous times. Any help would be appreciated!
I use no-op dock.
As to custom rom that WORK a 100% I can't find any.
My daily driver is a mildly moded Telstra stock rom.
See link below. Go to the OPs Russian site & they have a poll of popular roms. I linked to their site in same thread.
You aren't doing anything wrong as far as the "audio loss" part is concerned when using the car dock. You're using the official Motorola car dock, and the ROM developers for this phone either don't own the dock or have no interest in fixing it (nothing against them, it's extremely proprietary). The audio is just redirected and doesn't come back without a reboot.
The reason the audio is redirected is that Motorola designed it to work with their also proprietary audio/charging cable, which splits a usb charging port and audio jack out so you don't have to plug an aux cable directly into your phone when you want to hear it on your car stereo. Catch is, this never caught on, because they didn't include this splitter cable with most of the docks they sold.
The dock has a chip in it (and a crap ton of small circuitry) that tells the phone not only what dock it's on, but integrates tightly with the smart actions included by default on the phone. The custom roms are made for standard docks, or custom solutions using the resistor value tricks that Samsung is famous for. It's unlikely that we'll see more support for this type of dock system unless the new Moto X uses the EXACT same system.
To bypass this issue for me, I disassembled the car mount and removed the offending circuit board, then soldered on this breakout board (http://www.jayconsystems.com/usb-mini-breakout-board-556.html) and finagled it in there (carefully) using some of that epoxy steel stuff you see in auto parts stores. This simply made the car mount what it already appears to be: a pure pass-through. You cannot get around this issue without either disconnecting the internal circuit, removing the usb jack portion from the mount altogether, or reprogramming the offending part of the ROM you want to use (because I don't think anyone's working on it yet).
Btw, if you spend $10 or more you get free shipping, so why not throw in the OTG cable (among other random things) if you don't have one: http://www.jayconsystems.com/usb-otg-cable-female-a-to-micro-a-5.html

Wow, good reply. I didn't know about the chip inside of the dock, but it makes sense since when I enter the phone into the dock it automatically goes into Car Mode.
I tried the No-Op app from the Play Store that Avi mentioned (thank you too), but car mode still started when I used the dock and of course I lost audio.
Stinks, I really like the OEM car dock. I'm in sales and rely on the GPS a lot for work. I always put the phone right into the dock as soon as I get into the car which is numerous times throughout a normal day. So no ROM's have working audio with Motorola dock? I guess I get rid of the dock or go back to stock.

I have the same problem (obviously). I have not done this yet but was thinking I would set up a Tasker task to reboot the phone as soon as it is disconnected from the dock. This phone reboots so quickly (on PAC at least) that I don't think it should interfere with much. I have just been too lazy to set it up

I ended up going back to stock (almost - Deodexed 98.16.3 Base) All good so far. I had one hiccup and couldn't hear during a call, but that was only once and everything has been peachy since. Just no cool custom ROM goodies...:victory:
Hi!
I had my S4 (I9505) serviced a few months ago. Warranty repair, they replaced the whole mainboard. The repair took forever, and when I got the phone back, I already had purchased another one (second hand) that I liked better (Xperia Z1 compact, I liked the size), so I tested the repaired phone was working, but no more than that. A few months later when I missed my big screen and some custom ROMs I took back my I9505 and started using it with stock ROM. I soon noticed people couldn't hear me when I was on speaker phone. Then I flashed a few aosp and CM based ROMs, and realized it wasn't a software issue: it did not work on those either. And when trying to dictate something, or use voice command, the phone just doesn't "hear" anything. So the same mic must be involved in those operations, which makes sense since it is when you speak from further away from your phone.
Unfortunately, months have passed since the repair and the phone is no longer under warranty.
I started investigating a little bit, and it seems there are two microphones on the phone. The regular one works well but the other one not at all. So, here are my questions:
1. Is the second microphone located on the top of the phone, next to the headphone jack? If anyone has a diagram or picture of the board with the second microphone marked, I'd be happy to see it
2. How is that second mic connected to the board? Is it a cable, a contact or is it welded? Or is it integrated on the board?
3. If it is a part that can be replaced, where can it be purchased?
4. Anyone has had the same issue? If so, could you solve it?
Thanks in advance!
Cheers!

Hello. I want to start off and say that even tho i used a lot of phones Samsung fits me bets. With that in mind i want to tell the story of my broken s4 i9505. I bought it new and used it about 2 years until i got and iphone 5s. The phone remaind in a drawer with the intention of selling some time but forgot about it, then i used the phone once a week or so paired with moto 360 because iphone could not connect and used the watch only for time .(bluetooth worked fine remember this). Anyway i decided to sell it and i had all my apps and accounts in there so i thought the fastest way was to factory reset it and make it fresh so i can sell it (rom was not stock at the moment, i have no ideea what rom it was). I sold it to a friend that told me he wanted to pair something with it thru bluetooth and bluetooth didnt work...i sayd that it wasnt possible because all i did was a factory reset and that couldn't damage anything. Things got worse as the phone was charging very very slow and if it got over 90% baterry would not respond to anything (red led at 90% and got to green when full but still no response from phone) and the only thing to do is to remove battery. Then i took the phone back, got it a new battery but that didn't changed anything, took it to some repairs shops that didn't ever hear about this problem, i had it chance the software but that didn't do anything. The problem i suspect it is and i saw a few other posts online was the bluetooth module would stop working for some reason and do this to the phone. Currently i don't know what to do with it and i don't want to sell it just for part for 50 euros or so. Also i read that the bluetooth module can't really be changed as a spare part because it's part of the motherboard and that means almost all the phone. Phone is in mint condition, i didn't damage it before the sell , the buyer didn't damage it or messed with the rom...Another thing i noticed is that in settings under bluetooth address says unavailable. Can someone please help me ? I can provide more information about serials and stuff if needed. Also wi-fi doesn't work now.
Mine also show unavailable under Bluetooth address, but it works.
Are you currently on the stock rom?
Yes is stock. Android version 5.0.1 I9505XXUHOJ2. If i toggle bluetooth on says starting bluetooth then after 5 seconds it disables. I guess the problem is from hardware not software. So fast battery drain is not normal something is using a lot of energy.
As far as I know, the Wi-Fi and Bluetooth modules are in the same physical chip, therefore something might be physically broken. Here's a clip I came across while trying to fix my phone's Wi-Fi and I think it's exactly what might fix yours. (Should be very cheap to do too.) I think basically what he's doing is putting some flux on the board then reflowing it with the hot air gun.
Before taking that step, be sure to exhaust the possible software fixes. I'm not sure, but updating the bootloader and modem MIGHT fix it.
My wi-fi started working again it just took a while but the bluetooth does exactly the same as in the clip so maybe that's the problem. I don't understand why does so glue over it make it work...also for me it's hard to turn the phone off because the screen goes black but the blue led still stays on and the only way to turn it off completly is to take out battery. Maybe this will solve the battery problem aswell ?
