Getting no signal after a hard fall

Anyone can help me, my TyTN fall from my home stairs and I can't get signal after that.. I checked at the "Device Information" in the setting and it shows no Radio ROM.. so I try to install the radio ROM but im getting error during the installation.. I believe it is the hardware faulty and appreciate if anyone knows what is it and where can i get the replacement of the hardware..
FYI.. my TyTN can still be operated, its just cannot get the signal..
Thanking everyone's help in advance....

i'm not sure if you resolved the issue or not, but i'm selling an AT&T 8525. I'll sell it to you for $300 shipped as long as you live in the usa.

I'm not familiar with the insides of the phone, but there are a few options. 1, open it up and find out what's wrong. There could be a connector or circuit that broke and would only require minimal effort to fix. 2, find out if HTC can repair it for you through non-warrenty repair. 3, buy another phone online(like through ebay) that's only good for parts and use it for repairs.
Of course, if you don't feel up to opening it up, you could always find a friend or repair shop that might be willing to try.

ok one of these days i am going to write a book on how to re-attach antennas as the one in the TyTN is similar to the herm100 i presume
you cant miss it, its a big gold rod that slots into a V clip on the main board, a serious jolt could pop its loose, but it wont take much to pop back in, just be careful when you put the cover back on

Yep, there it is top left

And here it is disconnected.
However, I'm not convinced there is sufficient space available for that pin to disconnect while the casing is in place. My fear is a more destructive M/Board fault.
Mike

he could have shatterd the V clip off the board

It's more likely the golden connector from the picture got disconnected than that a board or chip broken. It would require the CASING to break in order for the board to break.
Open it up, take a chance. It's not so hard, just scary the first time.

We could take bets on what it is! No that wouldn't be fair would it
I agree it's worth opening up to check the connection. Depending on how hard the fall was it could be a variety of things. Don't agree that the motherboard can only crack if the casing breaks though - I've seen many examples of cracked m'boards and hardly a scratch on the case.
The OP seems to have disappeared anyway!
Mike

Thanks for the replies.. i've just been busy lately..
Will try your suggestion later to check the golden connector 'coz i've been opened it up many times already so its not a scary things to do for me...
will report back the results

hey again mates..
I already check on the golden connector and it seems fine.. everything is in contact and no physical crack was found or whatsoever...
I believe my TyTN is having the same problem with the one in this thread because I have similar symptoms like
1/ i can't flash radio back (the process hang in a middle of the flashing progress).
2/ there's no Radio & Protocol version in the "Settings->System->Device Information"
3/ no IMEI in the "Settings->System->Device Information"
Anyway, Is there a way to write the IMEI no. for the TyTN? maybe if there is an IMEI no. in the TyTN then can I flash the radio ROM.. i think.. and its worth trying (if possible) . or maybe its a hardware problem like in the thread above...

same wif my herm100 hard fall and no more signal
think tat is crack in gsm chips,u just look forward on gsm chips to replace ur old 1,then should be fine and work well ^^

Z2 touchscreen defect

Hello,
I've just created this new thread to inform you about how my Z2 is broken after two weeks of use.
Today at noon the touchscreen started to do some unusual things, I wrote some messages and I recognized that I wrote multiple letters when touching just one, not one aside the tapped letter but at the other end of the screen.
I wondered how that happened, tried again and again, restarted the phone, nothing changed.
At home I called sony care to ask if anything like this was already known, they just advised me to "repair" the phone through pc companion.
Now I can say that nothing worked and I'm sure it's a hardware defect, by experience I would say it looks like water damage to the digitizer/touchscreen controller.
The flaps were always closed except for charging at the bedside table and I'm sure it didn't rain there.
I will keep you posted what is going to happen involving warranty and xperia care.

now I was able to use the manage attachments button, must have been an internal error, thought it was spam protection, too...

I had the same problem, after two weeks too. I got a new one, but now I'm scared...

This also happened to me when I'm texting, it inputs multiple letters. I think this is a software issue as it happens after making a phone call. I changed to TouchPal keyboard and it happened less. I think the Xperia keyboard has bugs as well. But it rarely rarely happens and I can't duplicate the bug.

Don't know what causes it, seems software related to me. Turn of the screen and turn it back on worked for me. Happened just once...

Lucky for you, problem persists at the exact same spots.
Since yesterday the touchscreen went full rogue a few times, "touching itself" everywhere for a few seconds.
Trying to change it at the shop of my provider today by implied warranty.

Check your screen with this app:
https://play.google.com/store/apps/details?id=com.easylabs.multitouch&hl=pl

Got the phone to my provider this afternoon, the shop assistant examined the device extensively and was pleased by getting informed about the older batch numbers that have some issues (mine was a 14w17 with off center camera and flash).
He started to write down contact details and a description of the failure.
Then he got to a support guide for checking the device before accepting it for warranty, in this guide there was a step to check the wetness indicator beneath the sim card slot...
Suddenly "ohhh...", he said the indicator turned red, i looked at the spot that looked to me like the indicator and said, ok, yes, seems like you are right, ****...
He said that he is very sorry but he can not accept the device like this.
I went out, knowing that he is not to blame for this, called xperia care and was really upset, asked for the nearest xperia care partner to do a water-proof test.
The woman at the hotline asked why I would want to do the test, I answered because the touchscreen is defect and the guy at the provider store said the wetness indicator went off.
She answered that the Z2 has no such thing as a wetness indicator, at least not one that is visible from the outside, the thing you can see is the hardware reset button and the pcb.
Went into the store again, went through all the steps and got a 1:1 change of the device, the shop assistant was amazed that I get a 1:1 change, that would nearly never happen.
We agreed that it may be that Sony informed vendors of faulty batches so that they get replaced without hardware checks and his support guide was an old version of the Z or Z1 because the device is still too new.
I'm happy that I get a new device without any more hassle.

So how is the screen of the new unit?

They would have changed it directly if they had a device in stock, they ordered a new device directly so that I hopefully get the new device on friday.

I have exactly the same problem with my Z1 since i upgraded to 4.4 and whats bad is that its even present in 4.3 when i downgraded. Before upgraded to 4.4 i never had such an issue, its very annoying!

Sorry for replying this late...
Got a device out of an older batch, it's a 14w15, everything is good except camera displacement.
I think the vibration in this device feels a little weirder not as good as in the last device.
I even got an unbranded decive, no magenta t at the startup and less apps to deactivate.
Keeping it and hoping that it lasts the next two years.
Thanks for your replies and support.

[GUIDE] Nexus 7 Motherboard Pin Repair (WiFi, Bluetooth, NFC)

I've had my 32GB Nexus 7 2012 (grouper) since it was released. I love it, or well, I did. Until about 12 months ago, the WiFi reception and speed plummeted into what may as well be hell in the stone ages. I couldn't find the problem. I thought it was something to do with software, as I had recently upgraded to a newer version of Android at the time. So, I dismissed it, and waited patiently for a fix. Nothing. So, it has been sitting there since KitKat was released, doing nothing.
Until now that is! I decided that I didn't want to look at it doing nothing anymore, so I researched far past page 2 of Google (Desperate times people, desperate times...) and I found this gem!
I strongly recommend you DO NOT perform that guide. It can damage your device even more. Instead, please use the guide below:
YOU WILL NEED:
Small knife or Electronics opening tool
Soldering Iron (Sorry)
Solder
Basic soldering skills
[URL="http://rover.ebay.com/rover/0/e11400.m1842.l5919/7?euid=f15f56b658ee4efebf0c8f34c466567e&loc=http%3A%2F%2Fpayments.ebay.co.uk%2Fws%2FeBayISAPI.dll%3FViewPaymentStatus%26transId%3D472422032026%26itemId%3D390820734137%26qu%3D1%26ssPageName%3DADME%3AL%3AOC%3AGB%3A5919&exe=11193&ext=27012&sojTags=exe=exe,ext=ext]Contact Fingers (As many that are broken on your device)[/URL]
Right, lets get started...
(Oh yeah, and to make sure you can't sue me if you mess up, I am not liable for any damage you cause to you or the device you're performing this guide on. This may also void the warranty on the device you are performing this guide on)
BEFORE YOU BEGIN!!!
Turn off your device
Ensure that your device is unplugged from any power source
1) Open the Nexus 7 carefully.
2) Find the broken contact(s). The red circle in the picture below annotates where one of the WiFi contacts is broken.

3) Put the replacement contact finger(s) in place
4) Solder the new contact(s) onto the motherboard ensuring that the solder is only touching that contact
It's important that the solder is only touching one piece of metal, as otherwise the circuit will be shorted and your device may be damaged.
If you have messed up the soldering, there are tools to remove the solder, or you can re-heat it and try to wipe/scrape it off. The tool you want heats up, and sucks up the solder off the circuit board.
5) Leave the device for at least five minutes
6) Once you have left the device, check to see if the angle of the new contact is the same as the other ones. If not, gently bend it into place.
7) Place the casing back onto the Nexus 7, and press to lock it into place
8) Boot up your device
And that's it, you're done!!!! If this guide helped you, press thanks, and if you're feeling generous, donate

Broken Link
Hi,
The link you have provided is no longer valid, I just thought that I would see what I could find and this is one of them:
hypertext protocol:worldwidewebdotdigikeydotcom/en/product-highlightslashwslashwurth-electronicsslashwe-secf-emi-contact-fingers
I can not be sure which one to choose. I see one very similar to what my N7 has just not 100% certain that it would be correct one and or fit.
Regards,

how does this apply to NFC? my NFC is not working and i opened the case, saw one pin was bended (NFC section PIN), tried to put it back up and it broke. You think that by fixing the pin will it work again?

Why not? If that was the reason and you rectify it, it should work.

[Q] Fix for 'borked' R1 Port?

So I did a stupid thing and recently stuck a paperclip in the R1 port that is located under the back cover to the right of the SIM card. Well, while my reception was in fact BETTER than it was without the paperclip jammed into the slot, now i receive literally 0 signal when the paperclip is taken out. The only time I can get signal is if I put any metallic object into that port. Has anyone else experienced this and found a fix? I assume I messed up the internal connection between the radio and the motherboard. Would soldering the connection back together solve this? I'm really in need of some advice as Samsung wants $160 to replace my phone and Sprint probably can't fix it at their shop. I'm stuck with this phone for another 7 months. Also, another problem I've been having lately which is even more annoying is now my phone will no longer place calls if I am connected to LTE. Normally the phone will shut off data when you goto make a call, but now it will no longer do so and the call will fail with "OUT OF SERVICE AREA". Also, I can receive texts, but when I try to reply to texts, it also fails unless I get on Wifi or I bump my phone down to 2g/3g (which also sucks). Please help This is literally the best I can explain my issues. I've tried different ROMs and I've even tried re-flashing stock back onto the phone and literally nothing works. I'm currently using the Google Play Edition Port and I've had better results with this than stock thus far, but if anyone has any ideas, please share them with me. Thanks!

The little buddy giving my phone signal...

Is it possible I just shorted out the Wifi/GSM Flex cable?? Should I try to buy the part and see if that fixes my problems?

Seems to be common among Samsung phones.
You most likely broke the port so it always thinks it is using the external antennas. If you do a few Google searches you will discover it has happened to a few people on different Samsung model phones.
http://forum.xda-developers.com/galaxy-s2/general/external-antenna-socket-warning-t1273292
From what I understand, you will need to either always have the paper clip in the phone to use it or ship it off to a repair center and have them replace the r1 port with a new one.
There doesn't seem to be a easy fix unfortunately...

well it seems the R1 port has actually fallen off...... this could be a good thing considering i may just be able to use some copper solder now.

Screen not displaying correctly (Green block lines, moving down the screen) - Fix???

Phone Specs
Stock O.S (5.0.1)
Rooted (and as a result, has voided the warranty)
I9505 Version
Battery in phone is Stock Battery
What Happened
I was using Instagram on my Samsung Galaxy S4 (i9505), after leaving it for a few minutes. Upon returning and pressing the home button, the screen began to fill with green block lines moving down the screen (as on the video).
Current Issues
When I turn my phone on, the center of the screen is filled with green block lines moving down the screen (as on the video). Rather than showing my installed apps etc.
The same occurs when I try to use recovery and download modes
Videos and Screenshots
I have uploaded a video and screenshots of what my phone currently looks like on boot, after the above:
https://youtube.com/watch?v=nlCvsjQEqkY
I've checked, there are no marks or damage to the screen.
And upon unscrewing the phone and looking at the motherboard etc., there doesn't seem to be any damage to the hardware either as below:

Just because you see no physical damage to the motherboard does not mean that the motherboard isn't the culprit. Another gentleman was having a similar screen issue and ended up reflowing (applying heat so the existing solder melts) the GPU in an attempt to fix it. I don't recall if he did get it fixed or not, but whether he did or didn't isn't relevant. What is relevant is that you clearly have a hardware issue here. Take the phone in for service.

Have you had experience with this fault before, do you know what the exact culprit is and how to repair? Thanks

There could be multiple causes for the problem you're having. That's why I recommended taking it in for service.

Although I'm glad someone has responded to my thread, you haven't actually told me anything of any real usefulness. Instead you've just told me to get it fixed (which is why I've came to this forum, so I could be told how to fix it myself)
My primary reasoning for coming to this forum, was to be pointed in the right direction when it comes to fixing the hardware i.e. replace this or that cable etc.
If you could help in that regard, this would be fantastic

No, I told you to take it to the service center, because they can pinpoint exactly what is causing the problem. Otherwise you're tossing darts blindfolded. You're guessing where the bullseye is and hoping you hit it. In short, it's not something you can fix yourself, unless you happen to have a solder reflow workstation.
