[ FEITENG H9500 ] Known issues and fixes

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?

[Q] Hardware Radio Issues with Nexus 5

I got a Nexus 5 off a friend for a decent price because he dropped it and bent it up a bit. After giving it a quick look, the only thing that seemed damaged was the black little coax wire that connects the main board to the board on the bottom (Assuming it goes to the antenna), The end simply got bent off. This was an easy fix, replace the cable no worries. The real problem is when I went to go test the phone after I fixed the cable, it doesn't get any cellular signal (Wifi/BT still works), draws a crazy amount of power and the 'Qualcomm WTR1605L' chip specifically gets extremely hot, to the point of overheating in like 30 mins. Rather than tossing a bunch of money into replacement components (or getting another nexus 5 with a bad screen or something) I'd prefer to narrow down the problem to one specific component. This leads to my question:
Does anybody have any ideas to how I can further troubleshoot and diagnose this problem, or knows what the problem exactly is?
I have tried a few things, like if I flash the LG G2 radio (A trick I learned I could do with my Nexus 4/LGOG, after backing up my EFS just in case), Wifi and Bluetooth still work while Cellular, GPS and most of the other sensors do not. This stops the big power draw and overheating issue, but doesn't really do anything to further identify the problem component. I noticed that the modem image could be mounted as vfat and you can mess around with the various parts of the image. I don't know which files do what, so I have thus far left it alone.
I know this seems like an odd question to ask here, half the time I see responses like "Send it into Google/LG and have them fix it for you" but that isn't really applicable in my situation
Also, I know that my SIM is good, it works in my Nexus 4, I know that my ROM isn't a issue, because I have multirom installed and tried many different roms. The Radio image shouldn't be an issue because I had updated the phone from 4.4 to 4.4.4/L Preview since I got it (Using the google images and flashall script). IMEI/Whatever the ESN equivalent shouldn't be bad, my friend had been using it before he dropped it.
Thanks in advanced for any ideas, and sorry for the long and comprehensive almost to a fault thread.

Dropping a phone can sometimes cause invisible damage (like BGA solder joints failing). Visual inspection can only tell you so much.

I used to build small electronic projects when I was a kid. When something overheated like that, 90% of the time it was a short or a the wrong value of component. It's possible the drop caused the antenna connector to short out. Try disconnecting the antenna cable and try again with the stock radio firmware and see if the radio continues to overheat.
(I'm not sure how flashing the radio would prevent overheating, unless the original firmware simply turned up the transmit power in an effort to contact the tower, but that's my first guess and should an easy thing to eliminate).

Thanks for replying! When I get home I will give it a shot and see if it still overheats, then update this with my findings.

If it is overheating then it must hardware issue. Worst case is that the PBC board has a crack somewhere because of the bent. Grab the service manual from the general forum and start mesuring the components to find out where is the problem.

Ah, thanks. Something like that should be a sticky. For future reference/making sure we're on the same page, I found the thread here: http://forum.xda-developers.com/google-nexus-5/general/service-manual-d821-t2791303

It seems to overheat with our without the antenna cables on the stock radio. I noticed that it still gets warmer than it should with the G2 radio, it just takes a lot longer.
That service manual is really comprehensive but unfortunately, it is going to take me some time to actually get to looking it over closely.

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?
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

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.

Please read my answer below

Which component did I destroy? (Almost all lte/hspa+/edge packets are lost.)

Hi,
I replaced the screen of my brother's Nexus 5 and even so the display works perfectly we seem to have destroyed a component.
I managed to connect the device to lte/3g/2g networks (see photo in the attachment) and sometimes a few packets are even successfully transmitted but that's an exception. Usually it is not even possible to load a website within a reasonable amount of time..
Wifi works.
Stock and cm13-caf firmware show the same behavior.
Like shown in the photo the phone is successfully connected to a 4g/lte network.
Phone calls on a 2g-network work.
Any ideas to which component we have to replace? Or any hints on what could give more information about the actual issue?
Thanks in advance!
Best Regards
Michael

Does the original screen still work? If it does, you could try moving everything back to see if that makes a difference.
When you replaced the screen, did you use a where the LCD/frame/glass were pre-assembled?

Thanks for your response.
I had two replacement displays and noticed the same issues with both of them.
(I bought a cheap one first from ebay which had multiple touch screen issues and only after that bought a way more expensive original replacement unit.)

Hmm, hopefully, it is not a motherboard issue. I would suggest trying the old screen is possible.
Another part that may affect signal would be the USB flex port cable. The other pieces that attach to the motherboard are the camera, headphone jack, USB charging/data cable, and battery.

We completely destroyed the old display unit after removing all other components except for the battery. This made it easier to bend it and remove the battery without damaging its enclosing.
I'm afraid it might be the mainboard but was hoping for a cheaper solution . The usb board is still a possibility since it routes a quite a few signals between components.... Are there some schematics of the device available online?

Haven't seen any schematics.
I guess you didn't use a hair dryer to warm the adhesive before using a spudger to remove the battery.
Examine the USB flex cable to see if there are any breaks.
If you get a phone with a smashed screen and working internals, you should be able to get the phone working.

I wasn't sure if heating up the battery is a good idea and since the old screen has already been damaged I really didn't care if it's even more so...

Heating the battery is fine as long as you keep moving the hair dryer around. The battery just needs to get warm, not hot. Also, you would heat it from the front of the phone, not the back.

I bought a Nexus 5 with a damaged display unit online and used its mainboard and antenna cables to fix my unit. Everything works again. Seems to have been something on the mainboard but I have no idea which component exactly.

Thanks for updating the thread with your solution.

Nexus 5 overheating problem and No Signal

Hi Guys,
I have a problem with my Nexus 5 in that it overheats to around 70 degrees (got to 101 at one point!) Just by being on, even without using it. It even heats up when you check the battery when powered off (by pressing the power button once) only by a little bit.
I also have another problem, the phone can detect the SIM card and displays the number on the SIM, but it says no signal.
A third problem is that when the phone is locked and the screen is off, it randomly restarts. This doesn't happen when the phone is in use.
I would really appreciate if you guys could help me,
Thanks

1. What rom are you using? do you use a custom kernel?
2. try reflashing factory images.
3. remove simcard and enable aieplane mode. check if it reboots or lverhears
the round antena wires come loose afaik. i ordered a new set lf antenas and replaced them. phone is much cooler and i get better reception and battery life

I'm running the stock android 6.0.1 which I flashed.
It detects the SIM but doesn't get a signal,
I checked and the wires are not loose, maybe I will order the antenna wires as a last resort.
If anyone has any other suggestions, feel free to tell me

Is your GPS working? My Nexus5 have same issue as yours plus GPS is Dead too. After some search I found that the GSM chip is the same of GPS so I think the problem is the chip itself.
