fell, now no signal - 8125, K-JAM, P4300, MDA Vario General

folks. the 8125 was always able to surive falls. but this time my wife dropped her one on a concrete floor and now no longer picks up any signal.
anybody have any thoughts?
it is completed stock. no flashed roms or radios. everything orginal cingular.
it just searches and searches for network and cannot find anything

Remove the battery cover, then remove the upper rear cover (careful prying will allow this easily enough). Verify that both antenna pins extend fully and are not bent. Use a scalpel or hobby razor to carefully lift the antenna (copper tape on inside of top rear cover), and push out the deformations where the pins normally contact the device. Reassemble. Turn unit off, then back on, and check for signal.
If it's still not receiving, chances are you've broken an internal component, and you're looking at a complete disassembly followed by part(s) replacement using hand tools. These days, it might be cheaper/easier to just buy another used 8125 and put your broken unit up for parts replacement. Just do a PIM backup onto an SD card so you won't lose contact/message data.

S100 Loses Signal

Hi, I hope someone can help me.
I dropped my phone a couple of months ago and now I'm experiencing a problem. It appears to work fine for hours then suddenly starts losing signal strength to the point where it goes altogether. I can start a call with 5 bars and be cut off with no signal in a minute even though I've not moved. It will nearly always lose the signal when I'm on the phone but takes longer when just in other use. All remaining elements of the phone work fine. Please can someone suggest what it could be as it is getting me down...thanks
I'm sure it's a hardware problem.
have got the same problem.Did you already find the problem.In the beginning the signal just dropped but know i even cannot find any service at all.
gr
I've had some luck by raising all the contacts under the sim card but the signal still comes and goes when I use the phone ??
Snap!
I droppped my phone the other day and it is doing exactly the same thing. Mine is a Qtek S110. I used to 'lurk' on this forum ages ago.. but [email protected] BACK to seek help! If and when I get my phone fixed I WILL post and let you know what it is, if I havent already found the solution here!
I think it definately has something to do with the SIM holder, whenever the signal decays and vanishes, if I take out the sim and put it back in it comes back straight away. if I just take out the battery and replace it doesn't
ok.. next time i lose signal I will do that. maybe even run some isopropyl alcohol over the contacts to make sure they are clean.
I will keep you posted in my findings!
(oh.. i tried a makeshift external aerial last night to see if I could see if it was an internal aerial fault. It didnt make any difference, so either my homemade job was [email protected] or it isnt an aerial problem, I'm yet to find out!!)
Cheers!
oh poooop..
that unfortunately didnt work for me.. Oh well. i even tried cleaning the contacts and making sure the 'sprung' contacts were connecting with the Sim correctly.
I actually lost signal until it came back 15 mins later.. hmmmmmmm!!!
Can anyone advise where I can look on the circuit board to see if there is any damage. I am capable of doing this and making a basic repair !!
I had a look at the mda strip down guide on here, but I could see any reference to the aerial or anything. I think I'll have to send off for repair! Doh!
I emailed HPC and they wouldn't take mine back as apparently it was not sold in the UK.
I think I'll give xdarepairs.co.uk a go. a mate of mine said they were good n' quick.
merceeeeeeeeeeeeeeeeeeeeeeeee
no wurries!
the unit that sorunded in red (in the Attached picture) is connected to the main board with tiny connector, and this connector is a male to female connector. the male is solderd to the main board and the female to the unit. my guess is that one of the connector parts (the male or the female) was disconnect from its soldering, and you need to resold it. but it is just my guess based on my experience.
I was taking a look at the mda-jam.pdf guide to removing the case and it suggests that the aerial contact on the board you have pictured is with the front panel.
Can anyone confirm if indeed, the aerial for the phone is the metal casing? That would suggest that the dents in the front of mine could have affected that very contact.
Would still like an answer to my previous post.. but I think I may have fixed my phone temporarily.
Using the above information I got a flat bladed blunt instrument (in this case a normal dinner knife) and carefully placed it into the empty sd card slot. Using the diagram from the case removal guide I applied pressure with the knife to the area where the 'aerial connector' rests against the front bezel, inside, whilst at the same time pushing on the front outer casing with my thumb in the same position.
The thought process being, that it may have worked loose.
Sure enough I have noticed a vast improvement in signal yesterday and today. I am going to keep an eye on the phone today when I go out to see if the signal stays up!
YAY!
Okay.. latest update.
The signal did drop out a little bit throughout the day, So I have taken it upon my self to put my electronic training to good use.
Using the (now much read) case removal manual I carefully .. and I MEAN carefully took my phone to pieces.
I was convinced that the reason my signal kept dropping out was either that something had worked loose or that there were some contacts that needed cleaning or reseating.. as I was able to get a signal by squeezing the case at the top.
So.. Here's what I did (In reverse order)
Page 9 straightened and cleaned the 3 contacts on the RHS plastic plate with isopropyl alcohol. Also cleaned the corresponding contact points on the main PCB with alcohol and dried with a lintless bud.
Page 10 3 contact points, top right and top edge left are the contact points I refer to above. Also cleaned the 2 sprung contacts at the bottom of the PCB RHS page 10
Page 16 cleaned sprung 'Aerial Output' contact with alcohol.. also pushed connector outwards to make a betterr contact. Also cleaned 'contact to the antenna' area and dried thorughly with a lintless bud. Any other contacts I could see were cleaned and dried too.
Whilst putting the phone back together I was very careful not to touch any components. Battery contacts and Sim contacts were also cleaned.
One thing to note in the manula is that it it possible to unclip the connector for the camera prior to removing the plate in page 8. However, it is probably best to follow the guide, if you are unfamiliar with the type of connectors used. They can break easily.
My phone booted correctly and is currently on charge.. I am checking functionality at this very moment and can see that the signal is good and all other parts / hardware functions appear to be good. watch this space! It COULD be one fixed phone!!
I can't remember who on this forum wrote the mda-jam.pdf manual, but I would like to publicly thank you as you have helped fix my phone!
I hope its worked !!! Let me know !
OK!
Well so far I have noticed a dramatic improvement on how the phone was. I am sitting here with full signal, whereas on Saturday I had between 2-3 bars.
I lost a little signal earlier today but as soon as I held the phone up, the siganl came back. So, it's not perfect, but the phone is useable now.
As long as it lasts for the rest of my contract, I'll be happy!!
Dood.

not able to get any service? help!

Ok, so today i woke up, and my phone no longer got service. I dont know what caused it. I dropped my phone last night and do not remember if I made a call after or not... But it was working last night. Would flashing a new radio fix my issue do you think? any insight would be good.
As you've dropped it, I'd open it up firt and see if the antenna is still attached (no cracks in connectors) properly.
I wouldn't flash a new radio rom as the radio is the achilles heel of the Hermes. It could become permanently bricked. Thats ALWAYS the last resort.
So, I do not at the time have a small enough screwdriver to get into my phone, because I am at school, but when I get one, where is the antenna located and what should I look for, I looked through the pictures on the wiki but none of them seem to show where the antenna is, please enlighten
You need a size 6 torque key, NOT a screwdriver or you'll kill the top of the screws.
The antenna is the large black plastic part at the top of the Hermes. Its directly under the back plate and pretty much takes up the whole top of the phone. There is a torque screw holding it and the flywheel circuit board onto the rest of the Hermes and he antenna has a copper coloured clip on the side next to the power button. See if its still connected or if the clip is cracked/damaged in any way.
Cheers...
i opened her up, saw no connection issue or any sign of damage what could my problem be, and yes, i did pay the bill

Disassembly of Legend (advises & some help required)

Hi there,
I broke my touch screen and tried to replace it by myself.
To make a long story short, I failed miserably (I broke the screen under).
However, I learned a few things I didn't met in the forum.
A- Disassembly of the case.
1- The Legend is glued. So, you have first to use hoven to melt the glue before being able to do anything useful.
15min/ 60 degree in the oven. Or use an hair dryer (I used the former).
2- Don't forget to remove ALL the screws (even the one behind the IMEI notice).
3- Don't try to open the camera lid before loosening the glue or you'll damage the aluminium body.
4- You have to unplug all the différent cables, so take notes to remember where all of them goes.
5- You must disassemble all the boards. There are 2 boards. One supporting the sim / SD connector, and one supporting the screen/touchscreen.
6- When disassembling the screen board, remove it by pulling the touchscreen at the bottom, and lift it up. don't pass a tool on the sides to remove it or worse, under the touchscreen, you'r tool will touch the screen under and break it (like I did). The screen is very, very fragile
Now, I'm stuck here because I can't remove the connector of the legent which is passed under the shield on the back of the screen.
I'm not able to remove the screen so I would like to know how to remove this shielding or get back the touchscreen connector to be able to replace it.
Once I figure out how to remove this shiled, I may be able to remove the screen too.
But now, I'm clueless (it was 2 in the morning when I gave up).
Maybe, some of you knew the trick to open this phone further.
I'd like to hear about it.
A little up to my post for the ones who did not read it till the end:
I can't remove the connector of the legend which is goind under the shield on the back of the screen.

mate it sounds like you have trashed your phone.they are built NOT to be taken apart.They require special tools and process to be repaired. The only thing i would suggest is contacting your insurance company and let them know that your phone was crushed under a car or something and then crush it under the car and you can get it replaced. If you dont have insurance, take some out and make a claim in say a month or two.
Its not an honest thing to do but your phone sounds busted and its the cheapest way of replacing that handset.
Post a pic of it if you can
Unfortunately, I have no rights to post a link or some put some pics.
Something about spam and profile that should be reviewed before being able show any pics.
This device is glued. No specialized tools are able to open it without removing it.
That would mean that the phone cannot be repaired, only replaced. My phone's motherboard was replaced, so at the service stations they should have special tools.
Fixed it!
Bottom right hand corner:
Bend the shielding back just enough to allow you to slip the connector in & then use a little glue to stick it back.
Maybe I was lucky, but my phones working as good as new again
I fixed my Legend
Guys, I know it's been a while since you talked but in case someone else is looking for this info, that's what happened to me:
I cracked the display of my legend and purchased a new one on eBay (roughly 40 pounds) - obviously delivered from Hong Kong but a genuine Samsung (in case you didn't know the Legen's screen as well as most of the AMOLED screens are Samsung's).
Then I used the above information plus some YouTube videos to give myself an idea as to what should I do. The result follows:
I used a hair dryer to heat up the back of the phone (camera and loudspeaker cover). Perhaps I should have been more patient as in the end I decided to use a knife with a very thin blade to lift it and I scratched the plastic and the aluminium body a bit. Anyways - the back clicks in but is glued in addition to that so you have to use both the heat and gently applied force.
Once you remove the back cover (which took me the longest out of everything) you should start removing screws. There's two behind the back cover and six behind the bottom cover (where the battery is). At this stage you don't have to remove all the screws - the bottom two, the one behind the IMEI and the one under the VOID sticker hold the main board but the two screws sitting deeper inside the phone's body hold the front buttons so you may leave them for now.
Now comes the trickiest part so read carefully: the main board is held inside the unibody by the screws (which we already removed), but is also glued right below the camera lens and along the sides. You should probably heat it up as much as you can and for a long time. I decided to do it the hard way. My dislplay was already cracked and it's the most delicate part of the phone so I said "whatever" and used the same knife as before - moved it alongside the screen (pushed it in gently from the front) until there was no resistance (the glue let go). Then I pushed and I heated the thing up and pushed and tried from every angle until finally the board slid out of the unibody. I hope you'll find it easier then I did as it seems that everyone describing it found it quite doable.
Now everything becomes easy-peasy. Remove the remaining screws to put the buttons aside (you'll have both the actul buttons and the tiny board with sensors - the latter sticks to the screen but once you remove the connectors, yu can take it off too). All the connectors are quite easy to remove if you hav a needle or something (just pull them out gently). I didn't worry about noting which is which as ther is practically no way you can mix them up - they're very different.
The rubbery plastic black surrounding of the board clicks in, so once you find the right spots you can lift them gently and take the thing off. You'll be left with the display covered by the shielding from the top and a thin metal board from the bottom. You have to remove two more screws to disconnect the main display plug.
And the final bit (that's where the thread's author had a problem I believe). My display was cracked but the shielding - fine. These two are glued together so I had to find some space for my finger nail and lift the shield. By slowly and gently pulling it apart I detached one from the other - and had to do the same thing with the metal board. Don't forget there's some extra stuff to remove from the back of the display - they're all glued but the glue will remain fresh enough for you to glue them again - this time to the new screen. The same applies to the front shield. I hope you won't let any dust sit on it in the meantime. You should have a screen protector on your new display if you bought it like I did. Remove it now and the display will be happy to stick to the old front shield just as if it was always there. The metal back will also fit in.
Now you can go through the above process backwards - just remember to connect all the connectors.
What I didn't do: I didn't use ANY glue putting the phone back together. As an effect the front shield is sticking out a bit (doesn't sit in the unibody tightly). It doesn't affect the phone itself but it gives you the funny feeling that something isn't 100% right. But I prefer that than screwing something up with a misuse of glue (glue can be disobedient).
The most important piece of information: the phone is working 100% correctly as if it was never disassembled by an amateur. Apart from two scatches on the back, the VOID sticker missing, the front sticking out slightly (less than a mm) and the missing battery slider (which I forgot to put back in and didn't bother to repeat the whole process for the sake of it) - there is nothing wrong with the phone. So if you ever crack you ever crack your Legend's screen - you can try fixing it yourself if you have the courage.
I would like to see some photos too But I'm never gonna take my phone apart - can't see the point

Nice thread, i myself am wondering, if a better gsm antenna can be fixed inside the phone. and connect them to the 2 connections.
Do you have any pictures of the inside housing etc?

[Q] RW6815 WM5 Dual Sim success

I've seen several posts, and here's my solution for my RW6815 which may well be suitable for other PDAs. A bit Heath Robinson perhaps, but it works.
I've never been very successful with those chip-based dual sim holders. I've tried several types on several phones with varying results. My solution relies on a 6-pole 2-way switch which electrically switches between sims. I've used this before with Nokia phones and now with the RW6815.
eBay is a good place to start, searching for "dual twin sim card adapter nokia" which are available for Nokia models 6610, 7210, 3310, 3330, 3410. These are actually replacement back covers containing the switch, two sim holders and ribbon cable with a sim-shaped plug on the end. The switch/sim holder assembly is secured to the back cover with double-sided sticky tape. Start by carefully prising the assembly until it parts company with the back. Discard the back cover.
Next, buy a high-capacity battery to fit your PDA. It has to be the sort which comes with a replacement back cover to accommodate the thicker battery. Discard the battery (in an environmentally way, of course). You will just need the back cover into which the new switch/sim holder will be mounted. Work out which is the best way to fit the assembly so that the ribbon cable/plug can be routed underneath the original battery. Drill a hole in the back cover for access to the switch toggle and secure the switch/sim holder assembly in place - I used a glue gun (take care not to melt the new back cover).
Then, fit your two favourite sims into the assembly. The holders are very fragile and easily broken. Take care. Then route the ribbon cable under the battery and insert the plug into the the PDA's sim holder. Fit the new back cover and you're ready to go.
Power on the PDA and it will fire up using which ever sim has been selected by the switch. To switch sims, simply put the PDA into flight mode (or power it off), move the switch to the other position and take it out of flight mode (or switch it on). That's it.
As it makes the PDA about 5mm thicker, this approach might not work if you keep it in a dinky pouch.
Be prepared for a bit of fun with airport security. Twice I've had a phone 'sniffed' by a machine. I guess it shows up as being a bit suspect on the x-ray scanner. It probably didn't help that I'd broken one of the sim card holders and repaired it with copious amounts of Blu-Tack.
Good luck.

[Q] No GPS even after new parts?

Hey guys,
My GPS can't get a fix. It had this when I bought it, but even with another GPS board it can't connect. This is what I did:
So my old HD2's touchscreen and buttons stopped working... They were already replaced by the previous owner.
I bought an old bricked HD2 (So I could put my working mainboard in there) and disassembled the phone. It wasn't as hard as I had expected, but the iFixit guide is excellent. So taking that one apart was fairly easy. I logged every part, putting it in a seperate bin.
Taking my old phone apart was a pain in the rear. The other guy who replaced it used hot glue to hold the LCD to the midframe, and some gnarly sticky tape to hold the midframe to the rear shell . As I used a hair dryer and a suction cup to remove the outer shell, I pulled out the LCD + digitizer instead of the entire inner phone. I was like WTF?. (Yes I removed all the screws)
But eventually I managed to take it apart. I removed the mainboard without damage. Because I wasn't sure about the parts in my phone, I just used everything from of the bricked phone. The flex cable, camera, BT coaxial cable, GPS board and the white GPS cable. Even the screws and the rear shell. The only thing I used from my phone was the mainboard. Nothing else!
But even with all the new surplus parts it can't get a fix! I run Hyperdroid 5.8, I used the Leo GPS injector. Is this due to Android or is the problem on the mainboard? Because I don't have a clue where I should look now.
I'd be very pleased if I could fix it! I want to go geocaching with it!
Thanks in advance!
EDIT: Everything else just works just excellent. Bluetooth, cellphone, WiFi, vibrating, speaker, flash, etc.
After Flashing WinMo 6.5 and letting it sit 30 minutes outside, it finally got a fix... Hell yeah!
How can the title be changed to [RESOLVED]?
It finally got a fix! See edit #2
