Sorry, I dont think you were knocking my idea. Everything you said is validand should be considered before taking a screwdriver to your phone. sometimes we forget that there are some who will quicklly take something from this site and try it without thinking it through.

i'm assuming everyone should know not to compare signal strength between WinMo and Android. Too many factors. This only makes sense to try if there was a sudden change in strength where nothing else can be assumed was the cause. If you have never had good signal, then this is likely not the reason as a new phone should not have this problem.

I would not recommend doing this for anyone who is still under warranty or a carrier's replacement plan as this will surely void it and will not allow you to exchange the phone for this or any other reason in the future. However if none of those apply, why not try it.

Man i love you! This thread fixed my girlfriends HD2. Full bars and showing H!!!!

Super stocked thank thank thank you!
[HD2 Android Q&A, Help & Troubleshooting and Genera] nyvz:
I can confirm I see an immediate difference with this fix.

I have been trying for months to figure out why my phone gets so much worse service than my wifes. My wife has a G1 and I have an HD2, and I frequently had poor or no service in NYC in basements or deeper into my apartment and especially out of the city. My wife would often have consistent service and 3G where I would have no bars or maybe 1 bar and edge.

I just got a Torx screwdriver set in the mail that I ordered, and T6 didnt seem to fit, but T5 did, maybe the ones I bought are mislabeled, but it appears the screws were Torx 5... It took a fair amount of work using whatever plastic pieces I had around to try to pull my HD2 apart. It does not appear to be nearly as easy as in the disassembly instruction videos, and I was quite afraid of breaking my phone especially after I cracked the screen of my bricked APAD a month ago while trying to disassemble it following instructions. Anyway, I raised all of the contacts a bit, especially the ones toward the bottom which seemed very low. Now my once spotty service in my bedroom here in NYC seems to be very consistent and my non-existent service in the bathroom even seems to now be much better with 2+ bars and 3G.

THANK YOU

Thanks!!! Works perfectly now!!!
[HD2 Android Q&A, Help & Troubleshooting and Genera] ryanusu:
It worked for my HD2! Signal is awesome!

Thank you thank you thank you. I've been flashing roms for months trying to find a fix. My wife and I each have HD2's and mine has always had half to no signal with a ton of signal jumping while hers has been perfect. To make matters worse we live in a basement apartment. I noticed when I took my HD2 apart one of the lower contacts was seated lower than the other. I pulled them both up evenly, pulled up the others too just in case, put it all back together and it's fixed. My signal is perfect everywhere I go. Makes sense that I would typically have "half" to no signal with only one connection properly touching.

This is by far probably the most useful post for HD2 owners that I've ever come across.

I've spent hours of post after post after post of people with similar problems. This is certainly a manufacturing issue and fix is free and simple. (if you're willing to void your warranty-I didn't care as I bought the phones used) I wonder if HTC knows about this fix. Would be nice if there was some way they did.
[HD2 Android Q&A, Help & Troubleshooting and Genera] raggajungle99:
I can also confirm that this work for me.In my case my hd2 was sent to htc to repair a broken screen,and i think at some point between the accident or the repair one of the flaps (at the bottom) became flat.I bent the flat one and right away i saw a difference.Now i have full bars 3g or H and i get a satellite fix within seconds.
[HD2 Android Q&A, Help & Troubleshooting and Genera] htccraze:
I think i should mention this so that anyone

might

be able to save they're warranty on they're phone. Now I don't know if this will work on the hd2 but it did work for my touch pro 2.

Also I didnt see that this is against the rules but if anyone knows it is or thinks its wrong or immoral to post then please contact me and i will remove it immediately.

without getting into a long story of why i had to open my phone up i'll just get straight to the point. I had to open my phone up but in doing so you damage the "void" stickers. so what i did was take a hair dryer to the stickers for several mins & put a drop of glue on a cuetip, once the sticker adhesive started to heat up i used the cuetip that has a slight bit of clue on it to pull the "void" stickers right up. Then when i was done replaced them as if they where untouched. i tried to get all the glue off while it was still wet. I'm thinking that since this has worked on my htc tp2 that it may work on the our hd2 as well. it looks to be the same stickers after all.

now like i said before i dont think this is good if you still have a warranty or if you don't mind voiding it but i do think nonpaq has listed a great idea based on sound logic. with the steps listed above i was able to put it back to the way it looked to the best i could.
[HD2 Android Q&A, Help & Troubleshooting and Genera] nonpaq:
I would think that if your phone is still under warranty, then it would be better to have if repaired under warranty. Why risk damaging the phone if you can get it repaired for free. In the case of TMobile USA, they will ship out a new (or referbished) phone and you can send back the bad one afterwards, so no down time. Since the HD2 is a relatively old phone already, and most have probably voided the warranty already by flashing Android in the first place, I would think there are no other options, either fix it (professionally for $$$$, or yourself for free) or replace it for a newer phone.
[HD2 Android Q&A, Help & Troubleshooting and Genera] ryanusu:
The problem is I've known many who sent their HD2 under warranty only to get it back with the same problem. I think there is a chance HTC may not know about the issue. The other problem is if you are near the towers your signal does come in strong. If HTC repair is in an area where signal is strong from the towers and this is not a known issue for the HD2 and part of the repair procedure then either they'll send back your phone with the same issue or they send you a refurb. I suppose it best to use warranty if you have it but if they still don't fix it after warranty then it's obvious they didn't detect the problem nor know how to fix it.

Can anyone call HTC repair and see if they know about this?
[HD2 Android Q&A, Help & Troubleshooting and Genera] ryanusu:
I think it's immoral but definitely not wrong. ;)
[HD2 Android Q&A, Help & Troubleshooting and Genera] nonpaq:
Thanks for the kind words. XDA has helped me so many times that its a pleasure to give back. No need to send any bubbly my way, however if anyone has an old HD2 with poor reception problems they want to get rid of, I would be happy to take it as a donation.::)

By the way, I already posted in the general HD2 forum with a l ink to this thread to help non android users find this. It probably is working as this thread ha sover 2000 views.
[HD2 Android Q&A, Help & Troubleshooting and Genera] ephumuris:
Yeah so i just broke one of the bottom right contacts...snapped straight off...am i screwed? What does that one control?
[HD2 Android Q&A, Help & Troubleshooting and Genera] ephumuris:
Oh f**k me the bottom ones definitely are for signal...now showing zeroooooooooo signal. Not bad for having the phone one day it's my personal best for breaking something :(
[HD2 Android Q&A, Help & Troubleshooting and Genera] nonpaq:
Sorry to hear that the contact broke off. I forget how big the pad on the circuit board is, but you might be able to build your own replacement with a conductive spring or aluminum foil if you have any MacGyver skills. All you need to do is bridge the gap between the circuit board and the connector on the inside back cover of the phone.

This picture from the first post leads me to believe there is enough space to do something. Just make sure not to short out the circuitry by crossing any neighboring contacts.
[HD2 Android Q&A, Help & Troubleshooting and Genera] ephumuris:
Already attempting the aluminium foil but i think a spring would be a lot better!

Got signal back but it's worse than before i started... :(

Hd2 poor signal fix

I tried the antenna fix for the poor signal issue. It totally fixed the problem!! Thanks for the tip:D
[HD2 Android Q&A, Help & Troubleshooting and Genera] jabberwock:
totally worked for my hd 2! Thanks!!
[HD2 Android Q&A, Help & Troubleshooting and Genera] RDionysus:
ephumuris,

Sorry to hear what happened. When I was doing the procedure, I kept remarking to myself how careful I needed to be, because the contacts felt very flimsy. I raised them

very slowly and gradually

.

Anyway, as far as the broken contact- I don't think you're gonna have any long-term satisfaction with the aluminum foil. One, the foil doesn't have any "springiness" and will not flex to keep in contact with the case; two, aluminum is a far inferior conductor to copper (especially kitchen aluminum foil) and three, I'd be somewhat concerned with possible galvanic activity between the Al & Cu down the line.

If you want to get this working again, but don't want to do any soldering, then I would recommend you get your hands on some conductive copper tape (like this: http://www.amazon.com/JVCC-CFL-5CA-Copper-Conductive-Adhesive/dp/B000UZ8SJK, or http://www.findtape.com/shop/product.aspx?id=329&setscreen=1&width=1567&height=919, and similar products may be available at your local Radio Shack as well--if there are any Radio Shacks left in Britain...). Cut a piece to proper width and maybe a 1/2 inch long. Depending on how thin the tape you have is, roll up the end 3 or 4 times to build up some extra mass, so when the phone is mated with the shell there is enough material to press against the inside contacts. Now stick the end (there is adhesive) of your home-made copper "spring" onto what's left of the original contact and squeeze it on with a pair of flat tweezers, so the adhesive makes full contact. Alternatively, you try rolling it up and sticking it on the pad side (inside the phone shell), enough so that it makes good contact with the broken clip. Just don't put so much that it prevents the other clip from contacting its pad.

Although thankfully I haven't had to rig anything like this for my HD2, I've used the copper tape in similar fashion over the years

on lots

of electronics projects and repairs (old electronic toys, in a digital car dashboard, a subwoofer circuit board), and it has never let me down.

Good luck.

Worked Like a Charm!!!

nonpaq,

I had struggled with this signal issue and had given up. Was moving and found my hd2 in the bottom of a moving box. If you decide to take donations, please private msg me and I will gladly donate money (dont have any old hd2) to show my appreciation.

ephumuris,

I would recommend soldering it back on; if you happen to miss up, just be sure to have solder remover on hand.

Hi And thanks for the tip.

I just did the fix, and so far there seems to be a big difference, much more responsive switching between 3g and H. I'm looking forward to getting home, where I usual have a very poor signal.

On a side note, I had a VERY hard time opening up my phone. I could se one of the lower springs being lower than the others. As I was lifting it up very carefully, my finger slipped a bit, and it felt like I had broken the spring, (like overturning a screw) So my heart just skipped a beat... But luckily it wasn't broken...

So Thanks again

Here's how I did it, in a nutshell:

http://xdaforums.com/showpost.php?p=17410261&postcount=16870

as of this writing, I increased my signal from -101dBm, 6 ASU to -63 dBm, 25 ASU
[HD2 Android Q&A, Help & Troubleshooting and Genera] pico98:
I have opened my HD2, which was harder than it seems in the video, to see that one of the contacts in the top right corner, was slightly more bent than the other.

I lifted it up gently, as well as all other contacts because I didn't want to repeat the difficult disassemble operation. I assembled it all and powered on the phone.

I saw no change in GSM or WIFI signal strength before and after the operation but since several users were successful, I admit that probably there is nothing wrong with my phone.

I have wished that this operation would boost signal strength because my feeling is that my nandroid HD2 has poor signal.

I use radio 2.15.50.14, HSPL 2.08, magldr 1.13, CWR v4.0.0.0 and hyperdroid CM7 v3.0

Thank you for posting this but I wasn't one of the lucky guys.

Hi mate, the general concensus is that the bottom contacts are for the Radio my man, i think your Bluetooth should be awesome lol.

---------- Post added at 08:21 PM ---------- Previous post was at 08:11 PM ----------

Hi Nonpaq,

I have done your fix also.

I must say that my signal has been boosted.

Now regularly showing -89Dbm 12asu which is still fantastic for indoors.

Better yet, there were bent contacts in the top left corner.

I have straightened those and my Wi-fi signal is brilliant.

You are a credit to XDA developers and i owe you a personal thanks.

Keep up the good work.

One thing i'll add to everybody who has tried this, whether it worked or not, (or whether you're Ephumuris, i feel for you man) don't you think you should click Nonpaq's thanks button? You still tried what he posted.

Thanks again Nonpaq, i never knew our phone was so easy to get into.
[HD2 Android Q&A, Help & Troubleshooting and Genera] pico98:
:) yeah Bluetooth signal is tremendous! But as I said in my previous post I ALSO lifted up ALL other contacts with no apparent success.

Not convinced yet... but ..

I dropped my phone on Saturday.

I have an issue when if my battery dies, I have to take out the battery to get the phone to turn back on.

I had to rush to the store on Saturday and didn't put the unit back in the otterbox and I dropped it. I had horrible signal, dropped calls, couldn't even get data signal most of the time.

I just did this fix, I never get 3G in my apartment but I did get mostly edge. After I dropped it I got no signal. Right now it has 4 bars 3G which I never got before but only if I put the phone down. If I hold the phone I get no signal but still have data.

The antenna were bent.. one on each corner. I raised them.

I will test tomorrow and let you know.

Does anyone know which spring is in the top right corner (screen faced down)?
[HD2 Android Q&A, Help & Troubleshooting and Genera] Tigermoto:
If you are screen down with the earpiece at the top.

Top left is Wi-FI - Via process of elimination,

Top Right is Bluetooth (2:41 in the video)

Bottom is Radio - General Consensus

Hope this helps.
[HD2 Android Q&A, Help & Troubleshooting and Genera] ceralon:
Thanks

The top right and bottom ones were bent the most.

I still dropped signal in my usual areas today. Also I noticed my screen is stuck - as if something is pressing against it and it goes crazy on it me clicking on my icons when I am not pressing anything. Going to re-try tonight.

[HD2 Android Q&A, Help & Troubleshooting and Genera] hhoffmanlv:
My Experience

My cell signal was, for all intents and purposes, non-existent in my house. Rural setting, could only get a signal down the drive by the gate entrance to property. Now, and this isn't an exaggeration, I have Full Bars. But, all isn't good. I had difficulty with my dis-assembly. The adhesive for the screen was all over the volume rocker and oozed all over other areas of my phones perimeter. I had purchased the phone from GreenCells and sent it back to them because the volume rocker didn't work to raise volume. The power button required abusive pressure to activate and dust was under the screen. They kept it for a month sent it back with volume rocker not working to lower volume but you could raise it? All the buttons at bottom of HD2 needing abusive pressure, and still bad signal. Though the Dust was gone from under screen, which is probably where all the Excessive Glue came from. So, back to my situation now. Excellent signal, but I lost one of the grounding clips, broke the volume rocker, in fact, how is that thing supposed to go? Lost the screen at the earpiece, lost wi-fi signal, and when I place a call, as soon as I press dial, screen goes black. Not good when checking voice mail and trying to input password! If, I apply pressure at top left corner of screen >pinch< screen will come back so I can enter password.. So, moral of the "tale". It REALLY works well, but Caveat Emptor as far as the technical level goes.

You are the man!!!!!

So ive been following xda for abut 2 years now, & its an awsum site.

After reading the threads when android was just new and we had to put the android OS on SD cards and run from the win mob 6.5 OS.

Its come along way since then.

Long story short, I'm now onto my 3rd HD HD2. I can confirm I have always had bad signals with these models, 2xT8585 & 1xT9193.

Recently my latest T8585 was getting really BAD reception & I started to get paranoid because of an app called SETDNS that claimed to get faster internet access, which it did, but it also got granted superuser permissions which I didnt like. So I deleted the app along with other suspect files in the system folders.

After deleting the app and some folders I started to get real bad reception the the next day I had NO reception period.

Still being paranoid of the app I have been searching hi and low on forums and also reflashed the stock win mob 6.5. Still no reception at all.

CONCLUSION: I Read this post, did the FIX & BAMMMMMMMMM!!!!!

straight up the HD HD2 was full on receptioned up!!!!! with G & full bars!

I recommend to any1 with any reception issues to go ahead and lift up the copper springs mentioned in the post.

WARNING: I had issues when I was trying to open up the case on my first HD HD2. These are quite tricky to open and put back together. I advise that you read as much as you can on opening them up. There are alot of threads that relate to replacing the screen which go into detail on how to open them up.

Also some have good quality glue to hold the lcd screen to the chassy, some have doggy glue. The one I just opened up has doggy glue, so now I have to get some epoxy glue to restick the screen down.

Hope my input helps all the HD HD2 modders out there & Thanx sooooo much for this post.

Catchas,

Just performed this fix in about 10 minutes and now my signal is rock solid again. Thanks a million! I had lost 3G about 3 days ago and yesterday, I had no EDGE either...

Two thoughts:

1) My outer casing was very difficult to remove. I have a T-Mobile HD2 and there seems to be a chip that has an adhesive pad to hold the casing together. Secondly, the rim seemed to have either a light adhesive or sweat fudge (nasty) holding the casing from sliding off as easy as it looked in that tutorial video. I ended up using a credit card to methodically get in there to pry it apart. A little plastic damage up in the top left corner but this thing is built so fine, I don't think that little ding will matter.

2) Can't stress enough how fragile those feet are. BE CAREFUL!

Help! - Piece fell out of chasis / BT & Wifi Barely working

So I opened my phone up and the pulled the radio contacts up, although they weren't really pushed down. My regular signal is the same.

However, now I can only get a wifi signal within 5 feet of the router. And with BT, with bluetooth enabled on the phone, if I turn my headset on it recognizes it and tries to connect but fails. Just stays on "paired, not connected". I tried to make sure those contacts are touching a 2nd time, with no improvement.

When I opened my phone a small piece fell out and I'm thinking that's the culprit. I attached a picture of this small piece. Can anyone tell me what it is and where it goes? Will this get my BT and Wifi back to normal?

Now I feel like an idiot for opening up my phone. Any help is greatly appreciated.

EDIT: This was the end of the wire that connects the BT / Wifi antennae board (top of phone) to the main board at the bottom below the battery. Its a black wire. I tried doing some surgery on it to recconnect this end piece to the wire but there is a wire within in the wire. I did my best to strip plastic off the wire and reattach but its so damn small I don't think I made a connection.

Does anybody know where I can buy a replacement wire?

EDIT 2: In case anybody suffered the same fate that I did....see this thread: http://xdaforums.com/showthread.php?t=819099

Based on my reading it looks like this will be a direct replacement: http://mouser.com/search/ProductDetail.aspx?qs=kL1ClTr6oBo225qBggllPw==&cm_mmc=findchips
