Hello,
my Note 3 N9005 have Reception problems.
I made :
- flashed other Baseband -> same result
- flashed back to Kitkat -> same result
- made a factory reset -> same result
- changed the Micro USB Port with the Antenna -> same result
what can i do now ? is there everywhere a contact on the Mainboard that dont make good contact ?
I buyed this phone 1 year ago , the seller changed display and display frame before!
Thanks :good:
you have the same problem as I do... does your wifi work well or there is also some minor problems (mine's reception is like 70% of what it should be).
experts said the problem was on the motherboard, but I don't know anything more as I'd like to avoid replacing it.

First the problem.
Like many others HTC HD owners and I encountered this problem 2 days ago (i have nolonger waranty). i just was connected to my computer thru USB for couple hours, when i tried to power it on, the phone display dont comed on, but the phone worked fine (i maked couple conversations. After that i started to read about this problem, a lot of problems, but no solutions.
I try everthing - put in refrigerator (it worked until i turn off the display, pulled the battery for the night, and one bucket with operations without effect.
i install mymobiler and i was sure that my HD is working without display, then i disassemble the phone and checked the connectors, but no effect either.
i am radiocommunication and electronic engineer, and i don't give up so easily
i pulled the main board, and blowed the main board with hot air flow solder machine (i blowed exactly all over the shielding, from the bottom side not SIM card side), i wait for cooling then asemble the phone, and voala "Its alive"
NOW I AM IN TESTING PERIOD. I WILL WRITE WHEN I AM SURE THATS WORK FOR ME.
i have no pictures but i will make when i disassemle the phone again, because now is not fully asembled.
cheers!!!!!
p.s. i am sorry for my bad english
p.s. i am so happy trallllalalalalalal
It's not uncommon to see bad phone soldering on HTCs phones. Guess their factory isn't working right. Good job btw.
72 hours later everything looks great, the screen works perfektly, touch too, wireless communication too. i will post after few test again.
p.s. its look like my battery now have better handling....
6 un grande!
Wow!!! It's a good new. I had the same problem and I will try your solution. I hope it works on my phone.
Cheers!
I have problem from another type:
The problem is with signal. It was perfect until one day, the 3G has gone & then start losing the signal some times 3G return poor or strong, I take it to the HTC service center in Saudi Arabiya & the told me you have to change the main board then they do it but the same problem still there.
Now still have the problem even after change the main board, is there anything if have to change it or do it???
Note: it files down from me before this problem happened.

did you try to change the radio???
This could be caused by bad SIM card. Did you try another SIM? In my country it's not unussual for SIM cards to start malfunction out of the blue. Also, check contacts for grease or dust.

Hi, ssory for a stupid question, but what is "solder machine" with hot air flow? Is it idustrial fan? If yes, it can give to great temperature and can damage motherboard.
Was your idea to solder again all solder connections and roads?

the solder machine keep one temps at all around 280 degrees celsioum, i thunk the chips can be demaged with temture about 340 degrees, ofcourse it depends of how long time you will blow over the pcb. i don't resolder all tracks and elements (i have no such technology in my laboratory), i just blowed the shielded part of the mainboard, because i know that i can blow some smd element and they are very tiny.
p.s. i use this JBC AM6850 solder mahine
p.s.2 yes it was my idea - it is better than to do nothing with this PDA and throw it in the cupboard
The solution still work for me...
bueno suerte...

Waranty? : probably not anymore
Problem:
I was angry and threw my SGS2 against the wall and after the display was broken. I bought a new display with a frame from a famous internet auction site with some extras on it. -> an original one
(
· Home Button
· Audio jack
· Vibrator
· Charging Port
· Ear Piece
· Microphone
and more...
)
So I disassambled everything that was missing on the frame and reassambled it on the new one. That made my day. I was very happy cuz it worked all well til I noticed that couldn't activate neither the wifi nor the bluetooth anymore. But it worked before broke the display. So looked closely to the boards in the phone but it looks fine. You can't see a damage on them. Oltough I stipped the waranty sticker carefully and placed it on the new frame you can see that there is dust underneath it. Now I think I have no waranty any more.
I did a Wifi test per *#*#526#*#* -> NotSet Driver loaded ng
Did not help out either.
Every time when I try to activate Wifi or Bluetooth the button doesn't even light up. It becomes dark green. Not the activated lightend up green just the dark still-try-to-activate green.
Who can help me? Google doesn't respond how I want it and I didn't find a similar threads.
Now I am really sad disappointed und can't believe it.
That must it be like what people feel after they get raped in prison.
I tried many firmwares old and new ones. -> didn't work
I tried many radio/modem files via cwm -> didn't work
I wiped all caches -> didn't work
PS: calling writing massages and 3g (mobile internet) still works
ooh sgs why couldn't you kiss me before you f***ed me?
Same here, I've been trying the methods posted by erdinator above, but could not get my Wifi working too.
ICS I9100XXLPQ Kernel.
The status is still the same; dark green, and trying its best to activate. It worked yesterday in the morning, but refuses to work from evening onwards.
I had a similar problem but a reboot fixed it but I'm on UK unlocked LP7
Well I just updated my SGS2 to ICS yesterday. Today when I wanted to connect to WiFi it got stuck on "activiating WiFi". Then the screen went black and the phone stopped responding. Had to pull the battery. Everything was fine after booting up, though it consumed like 5 % of my battery just like that. Even the battery meter shows a huge jump and a little gap even. Odd

Yea, I just got this too. When the screen locks, it just stops responding. The entire phone was almost like bricked. And when I force restart (hold down the Power button for 15 seconds) the phone, it rebooted nicely. But the battery drain is terrible.

... hi we are have same problems i have s2 no wifi and bluetooth jingerbread i decide to root in jelly bean 4.2.1 to see if wifi and bluetooth is fix but didn't work ...
i have a seriuos issue with this device
3 brand new devices all having the same problem with GPS.
it doesn't connect even for a second
i open gps status and toolbox, it recognizes 12 satellites but can't fixate on any of them.
changed gps.conf to the proper continent and country, still nothing.
could this be bad gps module on all of them?
version is v10a-eur-xx
Any, and I mean ANY Mediatek chipsed based phone has issues with GPS, at least in Europe.
This is the sole reason I avoid Mediatek like the plague.
Just Google "Mediatek GPS problem". There are possible fixes, but you have to try them out yourself.
I have the same problema whith my LG H420...
How can i fix it ?
I had the same problem minutes ago. The views may come from a-gps sinse it didin't detect any signal. The problem is that the 3 screws on the bottom of the phone, where the gps antenna is, get loose. I have tighten the screws and... it worked. Now it find singal and fix on sattelites indoor and outdoor.
http://forum.xda-developers.com/showpost.php?p=67805410&postcount=1522
Worked for me, on H440N.
When I Lollipop GPS was wrong , since I upgraded to MM GPS has improved a lot , however, often use the app " GPS Connected" to fix in a stable satellites
I tried everything but it does not set the satélites !
3 screws were tight !
But even then I squeezed more !
what can I do ?? :crying: :crying:
I have tried "EPO Tools free" by eben80 and the connection and stability of GPS is better
Rats, I have the same issue with my h440n ... it used to work now and then before ... like half the time. Recently it sorta worked 1 out of 10 times and now it seems dead completely. Maybe that's due to the fact that I dropped it seriously multiple times and recently even cracked the digitizer big time. I'm NOT with Mediatek so I should be fine, but I'm not. Has anyone else with the h440n had this issue and resolved it successfully? I'm trying to find sth on ebay but other than this
http://www.ebay.co.uk/itm/Loud-Spea...478333?hash=item25a70da17d:g:dRAAAOSwv0tVZK2P
I cannot find anything else as a spare part. Not even sure if that one includes a gps module ... just says speaker and antenna ...

The trick with tightening the bottom 3 screws, close to the speaker, actually DID help me. I tightened them quite a bit and that seems to have resolved the issue for now. Big ups to whoever it was that came up with this super easy fix and damn LG ... poor build quality, still an ok phone though, for the bucks.
EDIT: After some testing - the fix worked, as I said, but GPS signal is still somewhat poor. It is enough to get you from point A to B, in a way, but the signal keeps on dropping. It simply won't lock to any satellite gps, constantly loses connection and reconnects again, and then the same again. I've read there are some apps that can help with that. Will try out some. If anyone has a solid one that fixes this, do mention it.
We need to fix it soon, or we forget Pokemon Go!

Hello. I want to start off and say that even tho i used a lot of phones Samsung fits me bets. With that in mind i want to tell the story of my broken s4 i9505. I bought it new and used it about 2 years until i got and iphone 5s. The phone remaind in a drawer with the intention of selling some time but forgot about it, then i used the phone once a week or so paired with moto 360 because iphone could not connect and used the watch only for time .(bluetooth worked fine remember this). Anyway i decided to sell it and i had all my apps and accounts in there so i thought the fastest way was to factory reset it and make it fresh so i can sell it (rom was not stock at the moment, i have no ideea what rom it was). I sold it to a friend that told me he wanted to pair something with it thru bluetooth and bluetooth didnt work...i sayd that it wasnt possible because all i did was a factory reset and that couldn't damage anything. Things got worse as the phone was charging very very slow and if it got over 90% baterry would not respond to anything (red led at 90% and got to green when full but still no response from phone) and the only thing to do is to remove battery. Then i took the phone back, got it a new battery but that didn't changed anything, took it to some repairs shops that didn't ever hear about this problem, i had it chance the software but that didn't do anything. The problem i suspect it is and i saw a few other posts online was the bluetooth module would stop working for some reason and do this to the phone. Currently i don't know what to do with it and i don't want to sell it just for part for 50 euros or so. Also i read that the bluetooth module can't really be changed as a spare part because it's part of the motherboard and that means almost all the phone. Phone is in mint condition, i didn't damage it before the sell , the buyer didn't damage it or messed with the rom...Another thing i noticed is that in settings under bluetooth address says unavailable. Can someone please help me ? I can provide more information about serials and stuff if needed. Also wi-fi doesn't work now.
Mine also show unavailable under Bluetooth address, but it works.
Are you currently on the stock rom?
Yes is stock. Android version 5.0.1 I9505XXUHOJ2. If i toggle bluetooth on says starting bluetooth then after 5 seconds it disables. I guess the problem is from hardware not software. So fast battery drain is not normal something is using a lot of energy.
As far as I know, the Wi-Fi and Bluetooth modules are in the same physical chip, therefore something might be physically broken. Here's a clip I came across while trying to fix my phone's Wi-Fi and I think it's exactly what might fix yours. (Should be very cheap to do too.) I think basically what he's doing is putting some flux on the board then reflowing it with the hot air gun.
Before taking that step, be sure to exhaust the possible software fixes. I'm not sure, but updating the bootloader and modem MIGHT fix it.
My wi-fi started working again it just took a while but the bluetooth does exactly the same as in the clip so maybe that's the problem. I don't understand why does so glue over it make it work...also for me it's hard to turn the phone off because the screen goes black but the blue led still stays on and the only way to turn it off completly is to take out battery. Maybe this will solve the battery problem aswell ?
Hi to all,
after change motherboard of my n910f (so it became a n910T), carrier signal became very weak, in every places.
Tried with 3 different bl\cp (for 910T). Also the newest. Tried with 3 different ROMs (1 MM 2 Resurrection). Checked the 2 wires inside. Tried SIM with other cells.
I'm afraid have touched something that broke some antenna, or so. It is very strange.
WiFi goes very well, as the rest. Only no signal, just a little.
Any ideas ?
I am facing similar issue, in my case i replaced the broken display. I get the full coverage only when i am in an OPEN area but other than (at work, at home) my phone is struggling to connect to network and people get "phone is switched off" message when they try to reach me. To troubleshoot the issue, i even replaced the SIM thinking it may be due to bad SIM card but no luck. Now i am suspecting that the latest firmware update from Samsung may have caused it. I am going to try out some custom ROM (i am on stock ROM until now) to see if it was indeed the samsung push that caused it.
Will post an update soon.
