BIG Reception Problem (Fast keinen Empfang bei MDAc mehr) - JAM, MDA Compact, S100 General

Hi,
I've got a serious problem with my Magician.
I used the antenna cable connector to get better reception yesterday when I had to drive a longer distance, but when I took out the connector it seems that the MDAc didn't switch back to internal antenna. I've got nearly no reception (~10% as usual). Driving back (without external antenna) I only have signal directly in front of a antenna tower. Normal phone use was not possible. Normally I have 1 -2 reception holes during the hole way.
What have I done to solve the problem:
1. Soft-Reset: nothing changed
2. Hardreset:
3. reinstallation of Radiostack 1.05.00 and Hardreset
nothing brought a difference.
Hope the external antenna didn't damaged my Magician phisycally.
Hope someone can help
P.S.: Is the german T-Mobile Radio stack 1.00.10 somewhere available, so that I can try it with this stack? But I'm pretty shure that the radio stack isn't the problem, because it worked perfect for more than 2 weeks.

did you get this to work ? i now have a similar problem - very low signal. the difference is that i never used an external antenna....

@Saege: you can try to remove the cover of the antena-plug on the back side to check out if everything flipped back where it should be. i don't think it has anything to do with the phone stack itself.
cheers, lutz

Hi,
I had also reception problems....
I have found the the internal antenna is a metal plate you can see when you take the upper back cover off. The metal plate has 2 lips that go to the mainboard (you can see them at the top). you have to take a look if the lips are pressed good against the mainboard.
To open the upper back cover put a very thin and pointy object into the holes marked by the red arrow's.
The second picture show the antenna connection to the mainboard, the lips have to be on the golden squares on the mainboard.
Cheers

That's a good digital camera you are using, what is it? I need a new one.

i think it's an HP Photosmart R707

Damn,
he is right... r707 from HP ... hehe
Cheers...

:wink:

I have problem too with the signal.
If the XDAmini just came from a no-signal location, the signal comes back very slow. Sometimes you need to soft reset to get it back the soonest.
Please help.

Have been trying everything that has been said in this post about the non-reception on my magician.
In the last 2 days, I only had reception (1 bar) for like 2 minutes, and then nothing...
Is there anything else I can try or test or do to get it running?
Separate/replacement/external antenna to check if the gsm module is still ok and that it's an antenna-issue...?
any help is very welcome!
thanks

Wierd spkr prob with xda2.. plus take apart pics (56k Warn!)

As I've been lurking for a while, I thought I would sign up and ask a question as well as donate something in the way of pics as I noticed other members asking..
My xda2 loses it's speaker function a few minutes after I reset it.. I've done hard and soft resets, flashed another rom (127.181 currently), cleaned and checked speaker connection and it still loses all sound after a couple of mins. I'm sure it must be software problem, but what?? anyone got any ideas? I've read back through a lot of threads here but no joy with what I've tried so far.
These pics are me taking my xda2 apart to clean the contacts and thought I would photo my progress, excuse my camera and PS skills, not that clever, hope they are of some use to members;
There's 6 intial screws to remove after taking off back and battery:

Update: after playing with the xda2 all day, I've realised it loses sound when it goes into standby.. if I soft reset the sound is fine untill it goes into standby, then when I press the power button to wake it, there's no sound again?! Can't understand it as I reflashed with image from o2 site as well. Maybe a registry setting, but I'm not that clued up as to how to look at the registry, let alone know what I'm looking for. I'm running MS pocket pc version 4.20.0 (Build 14053). Thanks
Hi Scratch, i experience this problem before, when i broke my CONNECTORS (21 pin), i also did disassemble my XDA 2 and cleaned the speaker terminals,but to no avail. I think the Connectors has something to do with the speaker sounds. Have you tried using your headphone or headset? had you recently dropped your XDA 2 with the charger connector on it? Maybe there could be some pin desoldered from the motherboard. check it.
Please can anybody post the pictures, how to unscrew O2 XDA Neo or Mini, I-mate jamin, i-mat jam, any one with this shape
Thx u scratch i was open my device,but i really dont know how to change backup battery (Pic9),do you tell me more how to remove backup pin!Thx u
Resistance (Ohms) across working Microphone
Next time somebody has their Himalaya apart, I'd appreciate it if they could take the time to measure the resistance (Ohms) across their working microphone. I'm trying to troubleshoot a broken mic. and I'm not sure if it's the mic. itself or something else.
I was getting by just fine using the "wired" jack, however, I managed to break the jack in two. Since this happened after the mic. quit, I'm more inclined to think its the mic. itself. I've ruled out a software problem and I've taken the phone apart once already to clean the mic. contacts. Does anybody have any ideas?

8525 - No GSM/GPRS - No Service

Hello-
After dropping my 8525 and cracking the screen, I was able to replace the screen.
I am afraid I also damaged something that may have to do with the internal antenna. After putting the unit back together everything works except that it will not hold a GSM or DATA connection.
It will establish a GSM/DATA connection for a few minutes, drop and then start searching again. Eventually, I get a "No Service" exclamation mark. I have tried setting to GSM only and no 3G, but I get the same issue.
Any suggestions would be greatly appreciated!
JP
8525
try changing the radio to 1.40 1.41 or 1.43 and see if that helps.. do u hear anything rattling in the phone? did u do the replacement urself or send it out?
Thanks! I will give that a shot and post the outcome. No unusual rattling.
JP
Well...thanks for the tip...unfortunately...same issue. Changed radio to 1.43. Connects for one second and then starts searching all over again.
When I looked at the internal antenna, it "seemed" to be "all together". Anyone know where to get the hermes service manual?
Thanks again! Still open to additional suggestions...
Cheers,
JP
One other interesting tid-bit. I can see the antenna signal strength go from 4 - 3 - 2 - 1 bars before it drops the connection. Don't know if that is relevant?

A bit of a guess this but. In the following two pictures you see the aerial first connected and then disconnected. Note the short brass rod that locates into a brass clip on the m/board. I am just wondering whether this is not making a good contact. If the aerial circuit adjusts signal strength in relation to the connected aerial it is conceivable that it sends a strong but reducing signal due to the aerial not be attached/good contact at that clip.

Hi Mike,
My antenna looks like the first picture. However, I can dismantle and double check the connection. I have become quite agile at taking this thing apart.
Thanks for the insight!
Best,

Do Vibrants Have This?

Captivate owner here... Do your Vibrants have these contacts on the back?
The Captivate cover is made of metal. It is suspected that these contacts are antenna but we don't know for sure...
Anyone with a Vibrant care to post a pic or let us know about your device?

nope. none of that... pic coming.
No but what we do have is one antenna to the right of the Sim Card. It's probably for GPS, WiFi and BT. I can snap a picture if you want. The Captivate probably does use the back as an antenna because you don't have what we have.
Doesn't appear to.
Sent from my SGH-T959 using XDA App
nope nothing like that
but thanks for the idea, and the shot of that optional antenna lead socket next to the sim card - mine has the plastic plug over it and was meaning to pop it to get a look at it
question - is the entire caseback metal or is there a metal band embedded in the plastic?
Yep, I'm an artist
Are you guys having problems with the metal back?
No problems, just curious what the heck it's for...

are you sure?
here's a better shot of what heygirl is referring to
that round plug cover, next to the bottom end of the sim card at the far left in the image, that well the plug is covering was identified in that dis-assembly video as the "optional" antenna" socket -that was the only reference to that optional antenna i've seen but, that would confirm what heygirl is indicating, that that is our antenna
but, then why is the radio signal on everyone's phone appearing to get weaker when they shield the bottom end with that "death grip" on the bottom end?
the area under the first three arrows (starting on the left) seems to be covered with a pc of black vinyl with adhesive, with the antenna, if that's what is there, underneath
there's also a well with a metal pin in it under the last arrow to the right - i'd be curious what role that plays or offers
it would be interesting to see the vibrant & captivate dis-assembled side by side and see what's interchangeable - iand if the at&T antenna setup could be used in the vibrant to upgrade signal reception?
That's for a lanyard.
The phone's cellular antenna is at the bottom, this isn't the cellular antenna.

Pretty sure. It's definitely not plastic and makes a metallic ring when dropping it down onto a glass table.

[Q] (Q) - Windows Phone 7 Wi-Fi strength

Hi,
Nobody knows me here but I've been on the HTC TyTN II forums but recently changed to a HD2.
Some dude I know had the HD2 and after some water damage (Water indicator is still white though) the reception stopped working. I started messing around with the phone and accidentally cut the keyboard flex while opening (doesn't matter, ordered a new one) and started flashing a new radio, MagLDR and WP7 builds by opening the phone and touching the flex cable connector with a screwdriver to get the correct key (hard as f*&%). {<<mod edit - ahem}
Now, on Windows Mobile (Original ROM, when I first got it) the reception didn't work. There was no signal and it couldn't detect any networks. But the Wi-Fi worked great. Sitting downstairs while router is 2 floors up with some thick walls worked. It kept connected to the Wi-Fi network.
After flashing the newest radio (2.15... or something) & flashing MagLDR 1.13 & a couple of WP7 ROMs, when I turn on my Wi-Fi, it shows my home network like this picture:

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
but with just 1 "bar/dot" signal strength even though the router is like 1 meter from me.
When connecting to it, it's a bit slow and in my status bar it shows a FULL signal strength sign (the opposite of what it showed in my Wi-Fi list).
I'm not sure how WP7 works when using the signal strength icons which is why I mention it.
I'm using the "I love DFT (7392 ROOTED) [YukiXDA]" ROM.
I'm hoping someone could help me with it.
I think that the radio only affects the reception & not the Wi-Fi?
Thanks!!!
Syntax1993
Nobody's got any ideas? Getting a new Kingston 8GB Class 10 MicroSD card soon. I hope it works.
from my point of view, its pretty stop im picking up wifi from a block down.
what do you mean with pretty stop?
Lol, solved. Sorry.
Seemed like I forgot to attach the Wi-Fi antenna onto the board.

Help! One metal contact on mainboard gone! What exactly are inside the lower bumper?

As shown in the photo, the second contact from the right on motherboard , next to the earphone port, now has come off (although it is OK in the pic). It should connect a metal contact in the lower bumper and act as some antenna. But what exactly?
I tried to cover the lower bumper with hands, which makes NO difference on LTE and 2G signal (but 2g looks like not very good itself). Neither 2.4 or 5 wifi . While 3G reception could be compromised, but not cut off.
At the moment, nothing obviously wrong has been noticed after the damage, but I am still very upset and would like to know what specific function or antenna that contact is responsible for. Best it was no big deal.
Thank you in advance.
By the way, disassemble it gently if necessary. Do not pinch it with fingers, otherwise we might end up on the same boat.
Check Android pay functionality as I believe that may be the contact points for your NFC antenna. Mine were bent and I had that issue until I was able to bend them back (was dicey).

Thanks for the tips. Yet in my case the NFC has been working fine. So there might be other issues involved.
I'm not 100% sure which contact you're talking about, if you could circle it on the photo that might help. I know that some of the gold contacts on the back of the handset connect to the metal rear cover and are for RF and EMI shielding. Perhaps if it's one of these you won't notice a huge difference in functionality

Just like this. Please check if you can see.
Yes, there are loads of contacts inside the back cover. But this one cant be discovered unless you dismantle the lower bumper by unscrewing.
