Bluetooth & SD Slot damage??

I have Dopod 818 Pro..
Suddenly, my SD slot isn't working, I already soft reset, Hard reset, Upgrade ROM from WM5 to WM6.1. Nothing is working,
so does the bluetooth. Everytime i enable the BT, its back to disabled.
My prophet is never dropped or damaged. it happened suddenly.
Any idea for solutions??

Same fault here. All was working OK, then it seriously corrupted an SD card to the extent that it can no longer be read by anything (I've not tried it with an other one yet). Also, Bluetooth will not switch on. The busy icon appears and it spins for 20 seconds, then just returns to OFF.
Radio rom downgraded back to 2.19.21
Hard SPL'd to 2.g4.4pda
Same fault in all WM5, 6 and 6.1 roms tested
*This began to happen _after_ I took the thing apart to clean and investigate the LCD high pitch whistle* Something has not bee put back correctly
Are there any images of the inside with significant items such as BT aerial etc highlighted? I need to get in there and look for bad connections.

I've fixed my BT problem (touch wood).
When reassembling the pda, the aerial panel surrounding the camera and speaker, was not put back into place correctly. There are three separate aerials on it.
Looking at the panel assembled in the phone, there is a small strip aerial to the right hand side, this has a single leg that extends down to contact a pad on the pcb. I'm guessing that this is the BT aerial by process of elimination
The leg got bent when removing the panel and did not make contact when reassembled. I also noticed that over tightening the two top screws will deform the panel and cause similar problems.
I now have working BT and the SD card reader has not caused any further problems.

wll, ive never open the PDA, and it happened suddenly. Im afraid to open the whole prophet to check whats goin on in there..
i0i, can you please explain me again step by step, by using picture? so i can understand completely of what you said ..hopefully i can rescue mine thanks

There is a good guide to taking apart the Prophet over at Modoco, the link is in the Prophet wiki. Otherwise there is a link to the service manual here http://forum.xda-developers.com/showthread.php?t=385944
It contains good photos and instructions. Like I said, my identification of the BT aerial is not 100%, it is only a guess based on things that work and don't work. I would not want to post photos with arrows that might be wrong. If you take it apart and look at the aerial panel then my description should be pretty clear.
Reading through the Service Manual and some posts in this forum it appears that battery voltage might be an issue with some of the more "mechanical" functions of the Prophet. Checking your battery for low voltage might be a wise step before cracking open the case. All kinds of bits ping off and it never goes back together absolutely correctly

Battery won't charge, power button broken, me going crazy

Ok, im going to start not from the beginning beginning, but from where problems started.
Friday night, went out, I was writing an sms when somebody pushed me and i dropped my wiz, i picked it up, to find that the battery was gone, nowhere to be found, i did find the cover tho. i tried to look for the batt, but i was in the middle of the club so it wasn't that easy.. I knew that a friend of mine had a spare one so i didn't worry that much.
Sunday I got the replacement, tried it, no luck, it ran out i thought, but when i tried to charge it, nothing happened. Buying a new one is not that easy when you are in Argentina, and they are expensive, so i decided to jump sart it. good news: it worked, i could turn on the phone, so the battery is fine. bad news: it still doesn't want to charge!
I previously had problems with the usb, and i had to have it soldered again, pretty strong, but I thought that might be the problem again, so i disassembled my wiz. new problem: the power button broke, the tiny, tiny black piece fell off, AND I LOST IT! DOH!
Anyways, the usb is still soldered pretty strong, i don't think its gonna go loose again, so thats not the freaking problem!
So now, instead of the initial no-charge problem, i have a disassembled wizard, that won't charge the goddamn battery, AND a broken power button (tried to glue it, but fell off again and thats when i lost the piece).
Regarding the button, i've studied my options, what would you recommend and how would you do it?
option 1: turn on the phone with the soft reset hole, and remap the screen on/off function to another button.
option 2: replace the power button internal piece with the one from the voice command button (i never use it). i've taken a look and they seem to be the same, but i don't know if taking it off and soldering it back would work..
anyways, that leaves me again with my initial problem, and i do have an hypothesis. I THINK (because I THINK i remember this happening to me before), that the battery won't start charging until windows has started, and the jump star power the battery has is not enough to get it started (tried to tape it and leave it for a while to see if it charged a bit more, but didn't work, the phone turns on but goes out when loading, and since i've my wiz pretty loaded it takes its time to load).
So to try this out i would need a way to charge the battery manually, and i don't have access to another wiz to have it charged (my friend had a spare batt because his wiz is broken).
So, if you have a solution to this, ANY different solution, or even an IDEA, please give me a hint!
For what i've read, this are common problems, so there must be something out there.

Man, that's a bad thing
I'll try to help you as much as I can.
You are right about Wiz only start charging when it's on. After my N78 was stolen and I went back to the Wizard, the battery was without any charge for months... I plugged it and no red LED... Turned it on and, bingo, red LED and charging!
The voice command and the on/off buttons are the same, so (in theory) it would work 100% IF you were able to change their places (at least for me, it is impossible to do manually, never found any good equip here =\ )
With a lot of patience (and a small soldering iron) I would try to take the voice comm button off and place it where the on/off was.
For the battery, maybe someone here can point if there is a "battery charger" standalone device, or such a thing...
Good luck man

hey thanks for the quick reply!
i'm not thinking of doing it myself, i'm not not that precise nor is my solder, but i know a guy, same dude that fixed my usb. I like that idea more than the other, but i guess that remapping the screen on/off and using the soft reset button would be much safer.. i haven't made up my mind about that yet.
Weir thing about MY wiz, at least thats what i think happened to me last time my battery was completely discharged, is that not only the device must be ON for it to charge, but it needs to have WINDOWS already loaded, i know for most devices it's not like that, but i think thats how mine works, or at least thats the only explanation i could find!
btw, i love your case modding concept, and since i might have my wiz sitting for a while, i might go ahead and try something too! nothing as extreme as yours of course.. i'd love to see more updates on your project along with some guide to see what ideas i can take

slight detail while thinking my options.. if i was to remap the screen on/off function to another button, would i need to have the device in sync? or connected via cable? because when i had the usb soldered, don't know how nor why (all the pins seem to be ok) but the device won't be recognized by any computer, usb only works for charging (or used to work, at least, still haven't figured why it won't charge now).
If its only an app that i can load to the phone, once i have it working (that if i ever will), i can load the app thru minisd, BT or IrDa so that would't be a problem.. i haven's investigated that issue yet.

Hey jinxie, how's your Wizard?
If you're still stuck with the battery (I hope not), check this out...
I think this will solve your battery problem:
http://forum.xda-developers.com/showpost.php?p=4963547&postcount=5
That's probably to work, just be carefull with the battery's temperature. If it starts to heat, stop the process and wait it to get normal, then start again.
Good luck!

i tried keeping the wires attached to the contacts for a while, didn't think it'd work better doing it just for a little and then repeating the process, i'll try that!
yeap, i'm still stuck and i think i will be for a while, i have to solve the battery issue first (would be useless to do anything else if i'm not certain i will get it to work), then i have to decide what i am going to do with the power button, and then i might paint it, i'm thinking matte black, or maybe take some ideas from your project if you have made any progress at the time!
thanks for the tip, i'll try it today and i let you know how it went

development: phone DOES NOT turn on with the soft reset button as i thought, i was sure it did, but after jumping the bat once again, tried the wiring method (not repeating the jump start but wiring it directly to de device pins), and tried to turn it on with soft reset and dind't work, while it does turn on with the power button, wich is broken, so in order to turn it on i cannot have the phone assambled, wich means that in order to try to make it work, i will need to hold the battery attached with my hands, and it is a pain in the.. you know where.
update: i wired the charger i was using to jump start the battery to the pins in the wizard, then held the battery in place with my hand, with a small screwdriver i pushed the broken power button. wizard turned on, IT FINALLY LOADED WINDOWS, but don't rush, i then (with my MOUTH) connected the USB wall charger to the port in the phone, and removed the wiring, i was expecting the goddamn light to turn on and the screen to tell me that my phone was finally charging. I WAS WRONG. then i had to let go because my hand was killing me and it went off
and the damn thing refuses to charge! what could it be????????
2nd update: I AM MACGYVER !
i figured the wiring had given the bat enough power to load windows on its own, so tried once more holding everything together with my hand but without wiring the pins this time, and at last the amber light turned on!!! im so proud of myself lol
SO NOW: device works ok, charges ok, battery has enaugh power to load windows, WHAT CAN I DO ABOUT THE BROKEN POWER BUTTON? i know you can't remap the power function since its hardware, but the screen on/off function might be remapped. soft reset button DOES not turn on the phone, is there any other way of turning it on? or my only option is to take off the voice command button and soldering it where the power button should be?

well, found the little button part that was missing, glued it (yes, GLUED it), and it kinda worked, i had painted the casing already, so i assembled everything back again. i used a folded piece of paper to hold the button still so it won't fall again and i think it was too big cause now its kind of hard to press but i can live with that, what i cannot live with is NO SIGNAL.. i mean, CMON!! are you kiddin me? now that the button works, battery works, phone assembled, and now this?? when i dissassembled the phone i forgot to take out the sim card, so the metal parts that hold it opened a bit, but i pressed them back, the sim in no way loose, so i guess i might have screwed the attenna :S
i've just checked, i can see the sim contacts so... [CENSORED] !!!
also now the screen looks weird.. like if it had less colours, like when you format your pc and haven's installed the graphic drivers yet, 3d effects look funny..

Hey man, have you painted ALL the Wizard parts, on both sides?
'Cause there is one that has a piece of copper board inside. It makes contact with the antenna. Without that contact, you'll never have signal
The piece I'm talking about is the one that has the camera protection, saying "1.3 MP camera". Look at its back and see if there's no paint on a green and golden plate. Remove the paint if it got there (the golden part is the important one, since it makes contact with the antenna).
Good luck man!

hahah lol, no of course i didn't paint both sides! but anyways im gonna take it apart again, clean it, and try again..
done. it had some paintng yes, but they were very tiny spray drops, so i don't think that is, anyway i cleaned it. On the other hand, i found that the antenna is loose on the left side :S what can i do about it?

[Q] Water damage

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..

[Q] WIFI problems after screen replacement

Hello Guys,
I just got my HD2 from repare, had to change the screen since it became unresponsive.
After I got it back, installed both WP7 and Anrdoid on it, I found out that the phone is not detecting any wifi networks. I tried in both WP7 and Android, and both of them do not detect any wifi networks. So it looks like when they changed the screen, they messed up WIFI connectivity. I'm guessing they might have forgotten to connect one of the connectors.
I am planning to take it back to them, but I was wondering if any of you knows which connector is for the WIFI, and if its easily visible once I take the back cover off, since I already done that before.
Thanks in advance

Hi dude,
if a connection is a problem and you even going to find it don't do it yourself.
it's a pretty small and gentle stuff, so you must know what you doing and how to connect them. Obviously you will need some serious tools.
my guess if you had all that - you already been doing this and not asking here.
so advice - not touching anything, not making it worse.

Best case: the connector came loose (which is not all that uncommon). It's the connector on the black wire on the top right side of the main board.
Worst case, they broke off a contact (which is also quite common).
Either way, don't try to repair it yourself but bring it back to the repair shop. If they accidentally broke off a contact then that requires a professional repair.

Thanks guys.
After some tests, I found out that the phone does detect wifi networks, but have extremely bad reception. I have to be very close to the wifi router for it to detect the network.
Any idea what might be causing this?

Like I said, either a loose connector or a contact has broken off. That will give you about 1 bar of reception while sitting next to your router...

[Q] Mytouch 4g wifi not functional after LCD replacement

I just recently replaced a malfunctioning LCD and shattered digitizer for my Glacier. Before I did that, the WIFI worked just fine. No problems at all. But now, the WIFI will turn on, but won't pick up any networks at all. All my other phones pick it up just fine, as well as my laptop. I've tried three different ROMs and I have the same issue with all of them. As far as I know, there weren't any cables that connected the WIFI module to the motherboard or anything else when I took it apart and put it back together. It's just a little piece that snaps into place, right? I'm not sure what's going on with this...

Seriously? Nothing? Every time I post on here, I get ZERO response... What gives? I see everyone else's problems being solved but not mine...

Sorry, there's no help to give. Don't act like you're entitled to something. I hate people like that. If you didn't touch the WiFi module through the screen and tried different roms then it went bonkers and its toast. TF are we supposed to do about that

If you're gonna post on here just to be a douche, you might as well not post at all. It's doing nobody any good.

All drama aside, he is right nothing to be done really. I guess you could open it back up again and risk breaking something more important than the wifi. Something may be put back in wrong or may have got ESD damange. Truth is unless you're just using this phone as a toy/dev/learning device and don't care if it breaks it is not worth the risk to open it back up.

Trying to fix my external speaker - I mess up working wi-fi. In addition, the case crack and camera button is not working. Should take it to repair shop. Too late now. It would be too expensive to fix it. You my still be lucky and shop will fix for few bucks. Lesson learn - do not mess with something that you do not understand( for me).

coax cable issue
there's 3 little coax cables - I've been told the white coax is the wifi but the black one fixed it so maybe they are all involved. In the process of getting to the LCD you went through these 3 cables. In most cases you wouldn't have disconnected them but certainly by accident it will happen. I put mine on 3 times before they stayed. There's quite positive click when connected but even then it may come loose while assembling the rest of the phone. I just finished swapping out my mother board and as perfectly as I could reassemble the phone I apparently lost one of the coax connections = no wifi. Went back in and this time the black cable somehow got caught under the camera board instead of on top and connected. Easy to see why this was missed because it looked connected.. well looked like it belonged where it was (wrong)
Anyway that's my wifi fix story - hope it helps someone
