yesterday i dropped my DHD, and i realized the wifi stop working. when i turn on the wifi at settings, it just said "error", and wont detect mac address.
thingkng it just rom acting abnormally, i just reflashed over, aaand.. it still the same. so i factory reset, and it still the same. so i came with a conclusion that the wifi hardware must be broken, so i gave a try to 'knock' it and it works!
so after a small knock again my wifi dead again..
i wonder if it possible to nudge the wifi module, but i dont know where the module located,
the service centre said, they had to replace the main board and cost $145, duh!
anybody had tried to work with wifi antenae?
happened to me two days ago
Check to make sure your battery cover is on properly and not loose. I'm pretty sure that is the wifi antenna.

i'm not sure the battery cap has anything to do with this, but i'm pretty sure the battery cap was snap properly.
yeah, i hope someone had the clue how to nudge the antena,
The wifi antenna sits in the battery door, it's the little metal clip you can see in the door when taking out the battery.
You can try to fix yours if it's broken, or buy a new one on Ebay.
Hope it helped.

It happened the same to me, I repalced the battery cover and still no WIFI.
I tried using an APK named "FXR WIFI Fix and rescue" it fixed it, but after a day it was unable to connect again.
Looks like it's time to change my dear DHD
Duh, is it so hard to try for yourselves before giving an useless advice?
I just tried wifi with removed battery cover and it's scanning without giving any error.
gampangingats, if you are using Sabsa, it's still possible that this is a ROM issue, happened to me a couple of times, but system restart (full) always fixed it.
Right. This is a royal mess here, with everyone giving different ideas.
First ensure that both covers (battery door & bottom SIM/SD Card cover).
Then try a rock stable ROM (BlackICE, or something CM7 based is always good)
Then try the rooted stock ROM (search for it, its here somewhere)
Report back once you've done all that..
If not, go to the Ace Think Tank (in my signature) and post there. Resident HW expert Glevitan can help you out)

I bought a second hand phone and it did turn on however there were a numbers of problems with my phone, it had a power button that didnt work, unresponsive parts on the lcd and a quiet in call speaker.
Your best bet before trying to replace the whole pcb is opening your phone using a teardown guide
http://tjworld.net/blog/htc-desire-z-tear-down
Make sure you read it a couple of times and go through the pics so you know what your dealing with, find the power button, make sure its intact and adjust the ribbon cables.
Otherwise just find a cell phone repairer on a classified ad like criagslist or kijiji.

I hate to say it, but it was second hand for a reason. Ever try switching the battery? How about changing the power supply?

Yes. Start simple. First check your electron hose to make sure you are getting power to the device. Also check the battery as well as the prongs that connect with the battery tabs. If things are good there, then think about tearing into the phone.

no no, dont say that.

As long as its not more than the phone itself.

You didn't mention water damage in the OP. You said something was loose. Water damage is completly different.
Try ebay.
Hey i found these 3 ads on ebay...do you guys think that a swap of the motherboards would be fine? heres the ads. I contacted the seller and they said the battery was used and thats it but phone seemes operational....i know its a risk, but is it worth it guys?
..need help on this one.
why swap the motherboards if the new phone is working fine. Just transfer data and you're done surely?

Reason being the other phones have minor problems, like speaker doesnt work, or some of those phones wont pick up signals and i think thats due to a bad radio flash or if i just flash a radio everything should be working fine.
can someone please clarify this? if i buy a phone with a speaker problem and transfer the main PCB board to my old phone...will there still be a speaker problem? or is the speaker a separate unit itself and not related to the pcb board?

one of the phones i am bidding for says it might not be able to guarantee a connection to mobile network (send sms,make calls) could that be a radio flash problem? would i be able to fix that??
another is one of the phones boots on and shuts off, i take it that could be a bad flash or something? its only about $20. just trying to weigh my options cause the new phones are lkike bidding for $350 lol im not that rich yet
I found out that my MOTHERBOARD is fine. There was water damage but not enough to go inside to the main board! My dad tested the battery voltage and found i wasnt getting any voltage.
i went to future shop and found a lady to let me use her battery and sure enough the battery was working and phone powered on!!! so i guess my battery was shot from dropping and popping out of phone while recording a video.

ordered these from ebay....are they any good? they look decent
Those look like the batteries I got. They were about 1/2 of the claimed mah rating. Worst case, they wiill get you running, and that charger is pretty good.

Hi,
I would like to ask for help and/or any suggestions that might lead to the solution of this problem.
Basically I was skating and had an accident and the screen cracked, which i got replaced, but then at the same time the network was connecting and disconnecting continuously. It sometimes shows the bars like there is good signal but i cant make calls or send texts, as soon as i try it shows a cross and no signal.
I tried everything from factory reset to changing the Radio/RIL to changing the rom. After a while I switched it to GSM only and it worked!!! So now the phone works on "2G" only which is annoying as the internet is quite slow. But as soon as i switch to Auto between GSM/WCDMA it goes back to doing that problem.
I would appreciate any suggestions, It might a damage to the mother board, but everything seems to run brilliantly on the phone.
Hi I've encounter the same accident too, but luckily I'd use casemate barely there, so it proof had protect my phone. You may need to sent for repair, as it sound so serious.
run an RzrU on the phone and send it to HTC or your carrier for repair. Definitely one hundred percent hardware failure

Hello Everybody,
Lately i had some issues with my DHD wifi
my device is rooted and i keep changing rom's from while to while
around 10 days ago i had used a rom and i noticed that when i try to enable my wifi it says Turning on and keeps like that
no networks showing, nothing happens at all just this stupid message and i had to restart the phone once or may be more to make the wifi works
i thought its may be something with the rom so i just changed it
i tried several roms but it still the same issue and since yesterday i could not made the wifi back on
whatever roms i change whatever restarts whatever removing the battery it still refuses to turn the wifi on
it just keep displaying the silly word Turning on all the time now
Does that mean i had lost my wifi connection forever, is it something with hardware now?
Please advise and help
Thanks in advance
Is the battery cover on properly? It's the pins that serves as an wifi antenna.

The cover is properly closed, you mentioned.
The little contacts are making contact? (pull a little on them to make sure they will)
Also cleaned the contacts?

yes, there is contactspray in the market, for removing the corrosion which blocks a properly contact. Dont scratch with screwdriver or something to "remove" corrosion. The thickness on the cover is very little.
I did it with the gps contacts and after doing that i had a less then 5 seconds fix. Before none....

So my note 2 has really really weak wifi signal, I am 20 ft from the router with only 1 wall between us and the wifi keeps timing out and sputtering.
I have turned off the power saving wifi and replaced the drivers with the ones from 4.1.1, I have tried numerous kernel and roms.
Is it time to open up the phone to look for a hardware fault?
Also screen sensitivity on the bottom right of the screen is terrible, trying to hit the back space key can be a nightmare at times

Found the wifi fix
I just figured out what the problem is, the wifi antennae in the case was buggered! I ordered a new back of the phone and replaced that and the wifi is fixed!!! I had a feeling that was the cause of the issue but I couldn't be sure till I replaced it. The wifi antennae is above the power button, with the back off you can see it as the long piece of plastic that is stuck in on the very edge. I had to buy a whole new back - it was only about $11 shipped. But it solved all my wifi problems.

I took the main part out of the chassis frame and found that the spring contact on the PCB (which is supposed to touch the wifi antenna on the chassis frame) wasn't springing up. I bent it up so it matched the profile of the other spring contacts and put it back in the chassis frame and all was well. My suspicion is your wifi antenna wasn't broken (it's just a bit of metal so there's nothing to break, really), just not quite touching the spring contact.
Same Problem

Sorry To Read You Received A Faulty Device.. :angel:
There Are Zero Wi-Fi Issues With The A70 On A Mass Level.
You Should Begin The Process Of Obtaining A New Replacement Unit A.S.A.P.
Mine drops frequently to the point that it's frustrating. Check out my post about the screen and tell me if you have the same issues too. We might have the same versions of the device, which appear to be a bunch of faulty versions from the same batch.
I'm having an issue as well. My old phone can and able to detect and connect to my WiFi (which is quite distant tho) meanwhile my A70 can't, I have to get closer to the Wi-Fi in order for it to detect/connect to it but after that if I return to the other place when it doesn't pick it up, I'm able to maintain the connection. It's weird..

Here you go buddy
That Wifi Master app is unsupported by the A70 so I don't know why you'd recommend it here
wifi is definitely one of the worst thing on the a70...it drives me up the wall, and i am ready to sell my phone and never touch any samsung anymore because of this...i am not sure, but samsung is trying too hard to make some things "smarter" meaning if samsung thinks your wifi signal is bad it drops connection just like that...exclamation mark, lost connection, switch to data, are countless through the day...and samsung is playing dumb about this problem...
my wife is using lg and meizu on the same network and wifi is working perfectly fine 24/7...
same here. my friend is able to get a stable connection on the same network with a much older phone. However samsung won't do anything about it.

As my A70 also has weak wifi issue.
Can't see the wifi router downstairs when my old. Samsung note 4 can, laptop can
I'm having the same issue. Weak Wi-Fi signal in my A70. While my other phones are getting full signal. Is there any way to fix?
seems like some antenna problem. you can probably fix it by bridging antenna contacts with the pins on the motherboard with a lump of copper wire. Solder can also help.
to take itapart:
1) insert a thin piece of plastic( like a flexible plastic file) into the gap between the rear plastic and frame, and cut the adhesive, and peel away the rear plastic
2) remove the screws and sim tray
3)slide your finger nail into the gap between the rough plastic and the smooth plastic on the side rails. The rough plastic is the part that is touching the screen, and the smooth plastic is the side rails. The smooth plastic is of a different colour, and the rough plastic is black.
4 pull the side rails away, and examine the copper antenna contacts. you might want to replace the mid frame. If you still have warranty, bring it back to store
