Possible Idea to fix death grip issue

I have had a idea about this for weeks and the soultion
http://www.maplin.co.uk/conductive-pen-33837?tabid=1&criteria=usb&c=so&u=strat15
As This pen is used to re-place broken conductive tracks on circuit boards etc
(for those want to know exactly what its for, read on the site)
my idea is to coat the back of the plastic where the wifi and gsm aerial's make contact with the board to amplify the signal, instead of the little tracks that htc have provided.
But my problem is finding a video showing the camera area removed without damaging it (where the wifi arial is)
I have been in the gsm repair trade for years, and i take this idea from the old nokia 3210's and the aerial's on those which used to just clip of and where the same idea.

i remember someone saying that the heated their phone to remove the cover near the camera (not sure how he did it)
you might want to try the software fix that is already available,many people said that their problem has been fixed after applying the software fix
but if you manage to open it can you report if there is any improvement in the signal attenuation in dbm?(using some app like wifi analyzer)
edit:found a video but how to open the back is not shown...

There was another thread in this forum (can't find it now) written months back where someone was trying and achieved successes removing back off phone, as you say by heating the phone to melt glue

Hi I've looked at numerous videos,but none show removing the top,and I don't want to heat up my beloved phone!!
I'll flash a new Rom,radio and kernel tonite,then the software fix and see how it goes,unless one of the custom time already have it included,and report back

I think that you'll find that most of the Custom ROMS have the wifi fix already in them.
This was the other thread that I remember reading before, hope it is of help..

Right i'm now on
coredroid desire s v1.1
radio 38.03.02.11_m (FLASHED SEPERATLY)
and mdj's kernel
I flashed v2 of the wifi fix after installing all of the above (even if the rom all ready instaled it) and i'm happy with result,even in the death grip i have 1 bar and that will do me fine,so no need to open up the phone
hope this helps any one out there

GPS is not working

Hello. i have a question. I have a problem with my mate 8. It's that that my GPS is not working (i don't get a GPS fix). I've sent my phone to the repair shop with guarantee, but they refused to fix it couse i have 2 slight dents in housing and apparently that is what is couses the GPS problem. (one dent is in area of volume buttons and the other is where the charging port is). It's really the dents that can couse this, or is the GPS itself? I could probably change the housing myself (they want me to pay 110€ for replacing it), but how is with replacing the GPS module itself? is it even possible? thank you in advance

its called an SoC (system on a chip) for a good reason, namely that the whole system is built into one chip or the same motherboard. so ud basically have to exchange the whole mobo ^^ maybe its just a bad gps antenna contact though...how did u get those dents?

Ok, that sucks actually then
Is it possible to figure out if the gps is bad without changing the housing first? I tried AndoiTS GPS TEST and i get AGPS in orange. Does that mean that module is fine? (I added a screenshot).
Oh, and I've got the dents whit dropping my phone -.-
And another question. Where is the actual antenna? Or is the whole housing that works as antenna?

Hi. I bought the phone on the 8th October 2016. GPS was fully working. On the 10th, I updated as there is an update showing on my phone. After the update. I cannot get any GPS signal at all. This is a bad update.

Flash
I had same issue after I incorporated the KANGvip tools into AL10369 , just flash the cyst from another ROM like b200 or similar. If you don't know how then flash ROM to a working Rom with GPS. Extract the custom backup from twprp. Reload the nonworking ROM and flash only cyst and boom cops can find u after via gps lol

thanx to finding this thread i kept on searching
i recently changed the screen on my phone and since gps failed completely (wifi also seemed to be lesser)
as the phone lays on the screen, the copper nipple in top left corner is the contact the gps antenna has to make with the case.
i placed some paper beneath the element holding this niple, thus pushing it up - BINGO
i get a 3d fix in no time like before
also wifi connection improved

Where is this nipple? https://d3nevzfk7ii3be.cloudfront.net/igi/BPviD4orcNjWNIdi

Mate 8 GPS fixed !
Finally, after weeks of researches & tests I found the "nipple" or copper pin !!!
It's indeed the one on the top left once the screen is on the table. Either you find a way to put it back in position... without breaking it (the best way is probably with your nail) or you just put some Aluminium (a tiny sheet of aluminum folded several times to get 1mn maxi alu to allow the final winding) in the rectangular "hole" on top right (opposite) of the metal cover of MATE8.
I discovered the "right pin" while testing to put a small aluminium foil on several places of the main board (once opened naturally) AND using GPS TOOLS (playstore) ! you have to wait several seconds to get the signal or at least orange dots on the "radar". Better to test first such tool first with a smartphone where the GPS is working fine and compare both phones while changing the place of the aluminium. Nevertheless, I hope you would not have to repeat my tests as I will clearly show the right "copper pin" in an attached picture ...
Hoping that helps.

Check water sticker on botton of sim slot

I had the same issue with a board i fitted to G930F bluetooth wasnt working nor wifi for no apparent reason i went through absolute everything firmware wise and system wise and couldnt figure out what the problem was i then removed everything once again looking for a loose connection it turns out the board i fitted in the top right hand corner there is a silver chip that controls wifi and bluetooth under the antenna there was a small black spot i noticed once carefully cleaned up i found the culprit there are 2 tiny fuses that blew conecting to the wifi chip this chip must also control bluetooth and NFC as that no longer works also.

Do you find a solution

I did find the solution unfortunately it requires the wifi ic chip to be replaced along with the fuses accompanied to the chip on the logic board but that means micro soldering the new chip on the other solution is change the board out when you take the antenna at the top off at the top right is the silver chip look at the circuitry and you should find a black burnt out spot also check the aerial for plastic burn where the chip sits
Thats the only solution available that ive found, not even the factory binary found the issue with the hardware though
That one chip though controls the wifi/bluetooth/android hostspot/NFC funnily enough though even though its blown visually the wifi toggles on still and will every now and then pick a network up for a second, the bluetooth toggles on but will not find any other device and other devices cannot find it either, the android hotspot turns on and broadcasts a signal but when trying to connect to it it will not connect, the NFC toggle is also set to on with the writing and toggle greyed out and NFC apps asking to turn on the chip but it cannot be toggled these are symptoms of the error,
If you would like to inspect your device,
If you dont know what your doing order a new backing i can successfully remove them without cracking them with a hair dryer, screen puller the cheap ****ty ring ones, and a guitar pick,
To start heat the backing of the phone up with hair dryer until its warm/hot next step is my secret trick to pop the watertight seal take the sim tray out and no **** blow into it youll hear the seal break get the ring puller pull it up enough to get the guitar pick in and just slide it all the way round,
Once the backs off theres 3 screws at top on antenna your gonna wanna use a phillips #00 for them once the screws are out get a pair of tweezers and slide them into the slot on the left side of the antenna where the vibrator is and pull up it will probably go flying if you use to much force but it wont break, the circuit and wifi module are now exposed on the top right diagnose the board for burnt spots if there is there, take the NFC chip off below the antenna and then the speaker to expose the charging port check the bottom right hand corner for circuitry burning also.

Hi, I have same problem for long, I tried all software options: factory reset, network reset, hard reset, wipe, firmware upgrade, downgrade,,
I can use NFC without problem but WiFI and Bluetooth are greyed out or stucking on turn on without finding anything.
Could you confirm what is the right IC for it ? I found two different IC number one on Ebay another on Part4reparirs , not sure which one is legit as both claim to be G930 wifi-IC (can't add link as I am new user)
also I would be interested to know where to buy fuse for it
I really miss my phone for few month using spare xiaomi now

Hey mate im a phone technician,
Ive got a few boards qnd broken S7 laying around ill pull one down and take a picture and label it and what not & will post it here for you,
The ic chip isn't actually a fuse its an actual chip which controls the wifi and bluetooth functions of the phone NFC is locted on 2 different part of the board aswell as wireless charging coil etc, so if that stuffed best of getting a new board, but however there is a small thermistor (ThermalTransistor) just before the wifi bluetooth ic hopefully for you its blown that and stopped current before getting to the wifi ic, i will also label this in the diagram
Hopefully in your case its the thermistor youll know anyway if it is will be blown with black or white residue everywhere and your antenna may be partially burnt out in that case, you will also need to check the daughter board for black or white burn residues also in the bottom right hand corner ill take a picture and label again also,
If i cant get the pics up straight away for you its because xda app is being a pain in the ass still and wont let me upload being playing up for a week now

Thanks for reply,, based on your explanation still other thing like antenna fuse thermistor could be damaged and ordering them one by one + shipping is not good idea.. I may better find cheap broken LCD S7 and ask technician to swap the board for me.
still looking forward to the pics... my Insta Gram acc is [at]kian.moments :fingers-crossed:

XIaomi Mi5S Plus 4+64 GPS, Bluetooth, Wifi 2.4 low signal

Hi, I've got an issue with my Mi5S Plus phone.
It finds only 4-5 sattelites via GPS while other phone finds 21.
Bluetooth works within 2-3 meters only.
Wifi 2.4 Hz works in 5-6 meters max and shows low signal strength.
Meanwhile Wifi 5 Hz works pretty well.
LTE works ok.
It's chinese phone with Global ROM 9.6.2.0 installed.
Mac adress in about phone is not empty.
Is that hardware or software issue?
Looks like antena issue but where is it and where are antena connectors in Mi5S Plus?
Will flash of ROM help? (I did not try it yet)
Any help is highly appreciated! I face such issue for the first time and searching the internet does not help.

open the phone, the antenna for anything except cellular are the tiny pogo connector that should be in contact with the respective pads in the back case...
clean the back case's pad for the respective contact points and try it again...

Thank you Crescendo again! I finally succeeded to fix it.
Chinese seller broke connector in the left upper corner of PCB when he disassembled phone to flash Global ROM via ETL loader I suppose.
I had to solder another connector and so now it's finally working as it should: Wifi 2.4, bluetooth, GPS signals are strong.
So it was 100% hardware issue, not related to software.
For other guys with same issue I advice to disassemble according to video on YouTube:
"Как разобрать Xiaomi Mi5s Plus (2016070) Разборка и ремонт"
And if you have same issue, bring it to repairman so he will solder you another connector fast and cheap.

thanks for the clear photo & pinpoint accuracy.
I can only guess the connectors coz they're plenty on top part of the phone... [emoji38]
Mine's not broken but the GPS (only the GPS) signal is weak... weaker than my wife's, same model same configs.
it all happened after I opened the phone for cleaning..., maybe the pin isn't making good contact with the antenna, I'll reopen it tom & try to bend it forward carefully...
again thanks for the clear explanation & photo...
glad it's all ok for you...

@dogrishin is it possible to repost the photos of the connector that you have fixed, they're gone from tinypic (perhaps upload to imgur or somewhere)
@Crescendo Xenomorph have you figured out which connector specifically is the GPS antenna?
I have the same problem after I had to disconnect and re-connect the battery. I haven't broken any pins or replaced anything in the phone but after putting it back together the GPS signal is insanely weak. Takes forever for a position fix and keeps losing it after. Also Wi-Fi is dead one wall away from the router. I've carefully bent all the pins a bit towards the back-case today and had no great improvement.

I think it's the second one from the top right, coz I broke mine & the wifi is gone...
Had to get it replaced to makewifi work again, but my take is usually just fix all connectors inside since I can't be sure....

@kaboom83 sorry for sooo late reply, but I could not find original photos....so now I just accidentally have found them and reuploaded to imgur. Here they are

LG Velvet-Service Disabled

I have a backup Verizon LG Velvet. I have the LG V60 as my main phone. With or without a sim the Velvet states "Service Disabled" and the bars have a small x next to them. I and Verizon have tried all the normal troubleshooting tips available.
Factory reset
Airplane mode on/off
Network reset and so on.
The sim works fine in other phones I tested so it's not the sim giving the issue.
Verizon tried on their end to get the phone to work but still kept getting the same service disabled. I'm down to thinking it's more a hardware issue than it is software. But not sure which internal module I should replace. The logic board or the lower PCB.
I even tried to lookup flashing the stock firmware to see if that helps via LGUP and LG Flash Tool. Neither I could get to work to achieve that goal.
Anyway, I was wondering if anyone could share an assist as to what is wrong or how to rectify the issue to the get the service to work on this phone. Anyone have any idea? Thanks.

Maybe the C port pcb. I know on Samsung phones one of the failure modes with the C port pcb is lose of internet and phone. It gets a lot of wear and tear. If it applies to this phone, don't know.
An experienced repair tech is probably your best shot...

They are generally inexpensive. Of course the elephant in the room is it could be the mobo instead... I hope it's the former.
It's also possible that the firmware was corrupted. A freak random hit by a high energy particle can do exactly that. A reflash of the stock rom be the next thing to try after the port pcb or maybe before depending on what you think.

Yes. The reflash was my first choice but couldn't find the right program to work with this phone and the right KDZ file I was having trouble finding. I kept getting errors with LGUP and Flash Tool.

I may have found my issue. I put the logic board under my scope and found some damage to the lower PCB like I thought and you mentioned. There is a "+" and "-" connectors above the charging port where the plate of the speaker connects to. The "+" connector is missing.
I ordered another charging port PCB and when that arrives, I will see if that fixes the issue and let you know.

So as it turns out, it wasn't just the lower pcb. Although it did need replacement as well. But it was the main pcb. So I ordered the main pcb from eBay for 60 dollars and the seller ended up sending me the entire phone in perfect condition and perfect working condition. LOL-go figure.
