Ok.. i see many people on this forum asking questions about this device.. the truth is this device is designed very poorly and it even may arive at your hands defective / with some or with a lots of problems.. you can proceed by your very own responsibility. Take a look in the picture for pcb details
- to Fix about every problem you need to findout how to unscrew the back plastic case and be able to see its PCB (Printent circuit Board) - Its pretty easy, just remove the little screws and give a presure at the clips of the cover to be removed, don't use metal objects because you will scratch the plastic.
* WIFI / GPS very low signal
Let me begin with one problem that you have FOR SURE.. is the low wifi signal and gps.. this is due to a horible design of the antenna.. the antenna is not just horrible, but it is also causing a short circuit it self! which is the main reason why the signal is low. First you have to stop the short circuit from happning
How to fix it? Unscrew the back cover, at the top of the back cover under the flash you will see a white sticker, this is the antenna, you have to remove completely this white sticker because it can't be useful by any way. Remove every piece of it including the copper-yellow color from the inside (the place that makes the connection.
Now find a UTP cable and take a piece of a hard copper of it, remove the plastic and keep the copper wire clear, cut it and place it in the whole were previewsly was the white sticker.. you have to place it in this way so it can connect with the inside conntact with the back plastic is placed and screwed again on the phone.. there are 2 pins in that place.. the old antenna used both of this pins (that was causing short circuit) you have to use the left pin and leave the right pin completely empty.. so the right pin doesn't connect anywere, and the left pin is connected to your piece of copper wire.
Cut the copper at the same size of the top of your phone.. so you can place it horizontal ... but you can also try vertical, (use wifi analyze app from play store to see what fits better for you)
Now.. this is the same antenna for gps.. you have nothing else to do.. just install GPS Test app and go outside and test your gps..
This is what i did and im pretty happy with it, instead i used 2 pices of copper and i covered the whole top place of my phone under the camera.. but that doesn't mean is the most right way because when we dealing with antennas there are a lot of math / and calculations that have to be done to design a perfect antenna.
the wire gives really a great signal.. just in case you want to reach the extreme.. Instead of copper wire you can use thin-Copper paper. (don't use foil of aluminium is not good) and design a better antenna copying the design of an antenna from another phone (that you know it works)
* Camera autofocus doesn't work - Or camera doesn't work at all
[Don't unscrew] Frist thing you should try is remove the back cover and give a presure in the right side of your camera with your finger.. this is the place the connector is located.. and it may gets unclipped and loose the connection after a small drop or something. After that Reboot the phone.
[unscrew back] If this presure on the right doesn't fix it, then you have to unscrew the phone.. take off the camera and give it some small hits and punches.. place back the camera and see if it works.. this is due the autofocus motor got stuck.
* Mic, Speaker, USB doesn't work
[Don't unscrew] This is due the connector of the bottom part got lost its connection. remove the back cover and give presure under the place of the SIM cards, were it writes 'WCDM' and 'GSP'. press a bit those spots. reboot, if not fixed:
[unscrew back] The two bottom connectors is 1. for the touchscreen and 2 for the bottom parts.. you need to check both of those because i am not sure which is which.
* SIM1, SIM2, Microsd not working
[Don't unscrew] Try to give some press next to vol+ / vol- buttons
[unscrew back] On the top left of the PCB there are located 2 connectors, 1 is for the front camera, and 2 is for the SIM/SD parts.. the last connector to the side of vol buttons is the connector you have to check and press to make sure is connected ok.
* Touchscreen doesn't work
[Don't unscrew] Give presure right under the headphones jack
[unscrew back] This is were it is located.
Charging Problem
I would like to add the problem with charging the batteries.
I got a new H9500, with two batteries. When i try to charge it with the adapter that came with it, the phone shows the charging animation, but it never actually charges the phone.
I have the same behaviour on both batteries.
After searching for a solution i found these:
-The charger supplied is 5V, 0.5A. Some people used a 1A charger and got to the point that it actually started to charge
-ROM problem, by changing the ROM some people were able to fix the problem, since the software was not getting correct info out of the battery's third pin.
Well none of the above worked for me. I hope someone comes up with an altarnate solution.
I need a new usb pcb for my feiteng H9500 (the usb port is broken on it)
This is the part I need :
the ones on aliexpress and dhgate don't ship to tunisia :/
my expirience
Hello guys...
My story. Bought this phone for my son for 160 €. We found out that camera focus didn't work, so I took it apart.
The easiest way to take down plastic cover, after it was unscrewed, is to put something plastic under it in the place between both SIM cards places, and work around inner battery square.
When cover was off, I found out that camera plug (right of camera) wasn't even plugged in. It only laid on connector. Plugged it in, and shake camera a little and auto focus came alive.
After that I noticed that black cable between gsm antenna and PCB was very loose, so I had to sort this out
At the end I found out that speaker connections are very delicate and had to take plastic down again to properly connect speaker.
Now it is obvious to me, why these Chinese phones are so cheap. We have saying in our country: pay little, get little
But now everything is cool and my son is happy.... And I am happy
Hi.
I just got a Feiteng H9500. The problem is that the camera is not working and the camera application hangs then stop responding then quit. When I start the camera nothing apears on display. I've put some pressure then some hits and it started to work a while. The focus worked as well but It seems to me not to work excellent so I gave it more hits, then the camera stopped working again. I have disassembly it, i moved a bit the camera and removed and put back the connector and it came alive again for a while, but just the front camera. Then stopped again. I have noticed that the camera doesn't move up and down when I press on it, it is stopped down, if I lift it with a needle it goes up, so it's not stucked.I can't even comute between cameras because the aplication hangs then quit. ( Everything else works.
any help? Thanks.
Hi Guys,
Just ordered the HTM H9500, is it exactly the same Phone as the Feiteng H9500?
I mean can I use ROMs for the Feiteng H9500 to flash them on the HTM H9500?
Big Thanx

My phone is Feiteng H9500 (HTM).
Appearance is similar FEITENG h9500, but not identical.
I'm not sure that have the same Rom, so I did not dare to flash a custom ROM.
View here:
http://www.movilesdualsim.com/forums/feiteng-h9500.166/
I cannot read Spanish or whatever it may be
There is a ROM at needrom called something like this "feiteng / htm h9500".
That sounds like the device is the same...

Thanks to your photo guide, I found courage and disassembled my HTM H9500 and DG300 phones and fixed them easily (nothing to fix really, just blow off some dusts between camera connectors and in front speaker)

You should order it by the store you got the picture of it. actually there are many stores selling parts for this phone.. almost like its branded.. unlike with other chinese phones you get a struggle to find parts, so you shouldn't face any problem to order a part.
Sound when touch on Lock Screen
hi, guys
I have FEITENG (HTM) H9500 almost a year and I am very pleased with it.
I want to change the sound of the screen when touch lockscreen, but I do not know how.
It did not sound when unlock the screen, it is the sound when you put your finger on the screen while the screen is locked.
In The system/media/ui is not, and I do not know where I'd be looking elsewhere.
Please help
No Data connection
I have had a Feiteng H9500+ for a while but recently rooted it and tried some different ROMs as well as applying a GPS fix. Somehow now my AT&T data connection is not working. The SIM settings have the data on and set to AT&T and I turned roaming on just to be sure but nothing I do can get the AT&T data to work. When I am connected to Wi-Fi it works fine. This is the only way I can get Internet.
Can anyone help me get my mobile data working again?

Hallo,
I upgraded my MDA to version 1.12 from Qtek, all works well, but I don't hear the person I call or answer. If I hold the phone (green) button for 2 seconds it switches to the backspeaker and than I can hear the person talk.
Does anybody know how to fix this !!! Help
Try inserting a headphone plug and remove it, this will prolly fix your issue.
can you tell me how to upgrade ?
I already download the mkBigStorage112.nb1 file

No, I plugged in a headphone and pulled out, but still no sound from the front speaker. Rearspeaker and BT headphone works well.
Anybody?
I noticed that the front speaker works when I have no sd card inserted, when I insert the memorycard again I have no sound from the front speaker.
Well by testing if its a software problem or mechanical it looks like it is mechanical, but is it?
Strange ??? Anybody
You would need to do a hard reset and see if the problem persists with no additional programs installed. Backup first though.
Yes, I did all I can do, but the problem is still there. I guess that the SD slot makes conntection with the microfoon or the front unit.
Oke, I screwd my MDA open and I looked how I had to put it back to gether again. When I opend it, I swa that this was not a brtand new MDA but I guess it has been repaired a few times, because I found pices of the seal every where. When I opend the back unit from the front unit my frontspeaker just fell out. So I guess that they forgett to screw this tinny PCB on. After I put it all together again, he works fine. The sound is now comming from the front speaker with or without the SD card inside.
Oke, for all of you don't do this at home unless you are prepared to buy a new one.
colderon,
I also am having the same problem and think it could be a "loose wire" or cruddy slip in the manufacturing. I will attempt the same. Was it just the two screws on the back at the bottom to start, then as it comes apart more of them. Thanks for your help!
Todd
Yes, their are two screws on the back pcb. Then their is a small sqaure connector at one site this one can be taken off, no the large connector with their cellotape. Oke now comes the tricky part, their is an other mall pcb, about 2 cm by 1/2 cm. This one has also an connector, but the small pcb/unit is glued to the SD card holder with dubble sided tape. You have to be very carefull an try first getting something between this small pcb and the sd card holder. If you pull the back pcb from the front pcb the connector will brake off and you have to buy an new small pcb. This small pcb is the unit that connects the front speaker and contains the signal leds (poweled, Bluetooth).
If have no clue what this small unit will cost me, but my is also broken. Somehow it works, but the signal leds don't lite.
Ik hope this will help you
I'm in the states and had the same problem, I ended up taking it apart myself and finding 2 things, 1 the speaker was bad, this is the same speaker as the n-gage or nokia 6610 either is available on e-bay. the other was the actual board that carries the audio has a plug on one end and the plug had a lousy solder job, for this you will have to find a local electronics repair shop, and hope they can solder as well as the guy here, since it all is surface mount technology. over all the soldering cost me $20 and the speaker cost me $10
Same problem, no sound this morning.
I remove the SD card, sound came back.
I put the Sd, sound still there.
But when I change the volume, no more sound...
What a #~{#[# bug
I tried to open my Jam 2 times and I quit... I'm afreaid to broke something... Where are the old times that everything had a screw and was so easy to unassemble???
Hi,
i've been upgraded my Magician Firmware first with this ROM:
JAM_WWE_11200_128_11210_ship.exe
and in second time with this:
JAM_ITA_11204_154_11210_ship.exe
In both cases i've the following problem:
Seems that device is always in charge mode (with cardle detached also). The Front LED is always powered on (orange or green depend on battery status) and it shutdown LCD after the time specified in Backlight Settings/External Power.
I'm very confused, i've been crawled very hard on google but i haven't found a solution about this.
Please Help.
p.s.: sorry for my bad english!!!

Has this been happening before the ROM update? Because it smells like a hardware issue, though it could be trouble with the registry settings in those ROMs (though I never heard of any reports of those ROMs doing anything weird).
Same problem when I dropped my o2 mini (with tmobile rom) , earphone of device became on /off since then and initially front led was always on . whenever earphone gets no sound again I just press a little not too hard (with the toothprick or similiar thin thing or very thing screw driver ) the SD card socket from inside towards outside (where we hear the calls from ) and while doing that I see the changing colours of front led like red , orange blue green . earphone sound gets back for 2-3 days and sometime light stays at green( if I don't check ) while charging . so I have to tab it again from inside to get it right again .Light contacts are near sd card socket as call speaker contacts .it gets mixed up after some drops or shocks . I'm no expert but that's what I'm experiencing and getting along these days .

You might have bent the contacts of the earpiece when you dropped the phone, hence the intermittent problems with the earpiece AND the LED (the LED is contained within the speaker module). Having opened my Magician before, I can tell you that this is more than possible, as the contacts that link the earpiece to the main board in the Magician are VERY thin and fragile, hence any bad shocks to the case may bend, or even snap the contacts.
In this case you will probably have to open the Magician to bend these contacts back into place - this will probably fix both your earpiece problems and your LED problems. Look here for more information, and a VERY good and detailed guide on doing this procedure:

problem solved with a piece of card
hi all,
my problem was:
led not worknig at all and no speaker working even changing it.
cause:
daugther board (that is on card reader) was a bit desoldered from mother board, look at the black connector on left (looking from the back). daughter board is glued on card reader.no human solder possible.
solution:
disassemble magician and put a piece of card (less than 1/2 mm) on the plastic cover, near the left of the speacker corresponding to the black daugther board connector.
it works great!
regards.
hello all,
after my tornado fel into the water i have a major problem.
sometimes i cant call, and when i try to call i only hear 2 soft "beebs"
sometimes when i am able to call it automaticly breaks the connection and again i hear the same 2 "beebs".
also sometimes people cant call me, but the screen says i have an connection.
i already put a new rom on the phone but it doesn't help so i ques it is a hardware problem.
I have another tornado for spare parst, does anyone know what this is?
maybe the antenna?
thanks in advance
It may be an antenna, but not for sure. You can try to disassemble Tornado and clean antenna connectors with any pure alcohol. If it doesn't help, it's PBA problem.
First you should have disassembled it completely and let it dry in all parts before using it again. Depending on how long it was in the water this may take some time. Taking fabric cloth and pressurized air can get it dry in a few minutes, but only if taken apart. Take care to remove the metal lids on the PBA as well and look inside for moisture.
There are no parts inside that take permanent damage from water if the device is without battery, but if it was on - end even used wet inside - then your prospects are variable. I would guess nevertheless that it should work again after all has dried.
thanks guys for the reply's,
i forgot to say that the phone felt into the water 1,5 moth before i started this topic. and 1 disambled the phone serveral times to make sure it was dry.
so inside it is dry now, but i tryed to use the phone with battery even when it was wet inside, so maybe that its where it went wrong.
what is the PBA? and where can i find the antenna connectors?
i already removed that metal box, and the chips underneath looks verry good. no corosion or what ever.
If you took everything apart already, then you should have seen the antenna connectors. The Antenna is located in the top cover at the back (above the battery cover). It connects via the two spring supported contacts on the upper part of the PBA (Printed Board Assembly). Both parts are gold plated, so it should not be a problem there.
Regarding the metal lids, take care to remove all of these (3). They are located underneath the keyboard (with the OMAP processor, RAM and the M-Systems DiscOnChip) on the same side of the PBA for the Radio and underneath the LCD.
As some chips are BGA soldered (soldered from underneath; BGA = Ball Grid Array), take care to blow with air also underneath (between PBA and CHIP). There is a very tiny gap between these and water hidden there may not dry for along time (if it has reached the area anyway).
However, the 2 soft beeps usually indicate that there is no free channel for you to be served (as far I remember) - you would get this problem with any other handset as well (same SIM assumed). It is a highly temporary problem (just retry) and you will not get evidence if you swap the SIM to another handset and retry there - network capacity has changed in the meantime and you would get a connection with the tornado as well.
If you experience call drops or other different behavior (compared to earlier) it may as well be attributed to a HW problem with the radio part in your device.
at this moment i use my htc hurricane with the same SIM card and i dont have any problems anymore.
so it is really a problem inside the phone. i havent used the tornado for 2 months now because it gets really anoying after a while.
i will take it apart for an another time, an blow some air underneath the chips as you say.
another symptom what i had was that sometimes the GPS connection was disconnected, and that the phone was searching for a signal for a long time.
but when i puted the sim card in my hurricane i dind't had any problems with the signal.
thanks again.
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?
Sent from my Huawei Mate 8 NXT-AL10
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

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.

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.

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:
