[Touch Diamond, MDA Compact IV General] hayyaan:
I've had this problem twice now..

both times after it fell on the floor, and the next time it fell the lcd stopped working!

the problem is that inside the diamond there is conjunction, where the flex cable of the display, board/keys and wifi/bt/gps all meet

most probably this connections gets loose or disconnected!

so you have to give it for repair and they'll fix it for you, htc shouldn't charge much for a simple reconnection of the cables

i payed around ~$50 though both times, but only because official htc support isnt present in my country.

good luck, btw in case your wondering i tried to reconnect the cable myself but it didnt work
[Touch Diamond, MDA Compact IV General] Nirak:
Tx for extra information regarding the conjunction and not being able to reconnect the cable yourself (What kind of connection has the cable? is it soldered?)

I was about to try it out when i realized i still have warranty.

Hopefully HTC won't charge me anything.
[Touch Diamond, MDA Compact IV General] hayyaan:
its not soldered, but i think you need to solder it for the fix, not sure

here are some pictures, from the service manual

as you can see.. there is a connection above the board and also below it, so it is a bit complicated to fix it yourself!
[Touch Diamond, MDA Compact IV General] muhrizky:
This is what i'm trying to say that the problems not arise from hardware or application. But from the Wi-Fi chipset drivers :(
[Touch Diamond, MDA Compact IV General] Nirak:
Am i correct assuming that those drivers could get corrupt when flashing roms and/or radio's alot? Is there anyway to obtain the drivers so that they can be replaced when WiFi error occurs?

As you can probably see, i'm a noob in this area and thinking as in PC terms, where you can try to install the drivers again when something doesn't work correct.
[Touch Diamond, MDA Compact IV General] muhrizky:
First, please take a look at this registry hive HKLM\Software\Drivers\WLAN for information about your current WiFi driver version.

As far as i know, all the device drivers reside somewhere in the OEM directory. So when we flash the ROM, the WiFi driver itself can be changed (depend on which ROM did you flash into the device)

Comparing with PC, i think it would be the same as in the Pocket PC (or Windows Phone) related to the OS-Drivers work mechanism. For example, we can put an OpenGL (display) driver into a device after flashing ROM.
[Touch Diamond, MDA Compact IV General] hayyaan:
is the bluetooth working fine?
[Touch Diamond, MDA Compact IV General] muhrizky:
absolutely
[Touch Diamond, MDA Compact IV General] hayyaan:
seems to me to be a hardware issue..

is the wifi button greyed out in the comm manager..

or does it show the busy icon when you turn it on and still remains off?

when you restart the phone does it say MicroP error?
[Touch Diamond, MDA Compact IV General] muhrizky:
Everything was fine with the H/w because the WiFi can connect sometime rarely (10% works, 90% failed)
[Touch Diamond, MDA Compact IV General] jasonkruys:
I had exactly this problem. I thought it was fixed by changing ROMS/software as the problem was so intermittent, and worked sometimes. Eventually the fix was to send it back to HTC for repair - they replaced the motherboard and I have been using the device now for over a year, through multiple rom flashes, radio flashes, and mtty connections with NO problems at all...
[Touch Diamond, MDA Compact IV General] muhrizky:
You have a valid device warranty or how much did they charge/cost you brother?
[Touch Diamond, MDA Compact IV General] toby_as:
Hi

What can I say/

I bought another HTC (with LCD broken) and i put my LCD on it.... now i have a fully working diamond. My "original" now is waiting for his screen.....anyway is good for gps and phone after all....when i have the money to by a LCD and touchpanel.

PS. I put my ''original" MB in this "new" HTC and the WIFI sarted but only one time..after that it wont start anymore...i put it back the "new" MB and its working again. So my "original" has a failed mainboard/naviboard or conection....
[Touch Diamond, MDA Compact IV General] diablob:
I have same problem, I must open Diamond and repaired. I repaired broken LCD. After this I had problem. Problem was with connector to mainboard and keyboard connector. This one had bad connect and wifi and reset button doesnt work. Device get device.exe error. It was hw issue, but not problematic corrected. :)
[Touch Diamond, MDA Compact IV General] muhrizky:
Well i guess maybe you are right and beside of these problematic WiFi, i still love my Diamond because of it's functionality.

Your comment is also enlightening thanks ;)
[Touch Diamond, MDA Compact IV General] toby_as:
Thank You

For me the lack of Wifi it was a major problem...i like the weather, the opera browser, messenger etc... the whole internet part of this phone.

My lcd has some wire broken on the conetion part...this can be fix?

Maybe my MB conetor is also problematic on my "original" diamond...how you fix yours? Thanks
[Touch Diamond, MDA Compact IV General] muhrizky:
Those links are refer to WiFi problem in diamond & there's another debug tool to help you diagnose TNETW1251 chip. Hopefully it will help any of us to resolve what exactly to be the main cause. Hopefully :(
[Touch Diamond, MDA Compact IV General] diablob:
I think that connector not possible to repair. Its so little. When is broken, mainboard you must change completly. I had broken LCD and touch screen. How you destroy connectors? Much touch? LCD connector is fix to LCD mainboard. Its impossible to change this one.
[Touch Diamond, MDA Compact IV General] toby_as:
Hi

i don't now how i distroyed...after i removed the lcd and put it back just won't start....no screen..only black screen and the blacklight? turn on.
[Touch Diamond, MDA Compact IV General] diablob:
And after turn on is silent or start up sound from HTC starting sequence?
[Touch Diamond, MDA Compact IV General] toby_as:
Hi, i have diaduit 1.6.7 ...so no startup sound....but i will try if i can conect to pc....

PS:

The phone is starting...working...conecting to PC...even touch is working (i can power off the phone holding the power button and touching the screen in position where the "yes" it shoud be)..."only" problem that is nohing on my screen ..except some white lines on the bottom.
[Touch Diamond, MDA Compact IV General] diablob:
When I first time assebly my diamond after LCD change I have same problem. I have bad connect diplay connector on mainboard ogf diamond. Its left from back of phone and little than key connector. When you reconnect you must get some little instrument under connector and touch to board from up side. This must do with key connector too. When connector is fine connect you see on mainboard. When mainboard get little up from right position, connector are connect without problem. When you have bad connecor position, connector get down from mainboard. Its simple. :)
[Touch Diamond, MDA Compact IV General] toby_as:
Thank you for your answer...but i tried to play with this conector with no result. So my LCD is broken...i can by another but i don't know how to put together with my working touch panel...
[Touch Diamond, MDA Compact IV General] diablob:
When you buy another LCD you have problem with connector between LCD a touch screen. Theese are connect by melting tintin. You must have hot solder. I have theese two thing new, I think that you not connect old one with new one together because connectors are so impressible to hot. Do you have Diamond service manual? On page 24 you can see where you must use plastic tool to correct connect LCD and touch panel connector. When use this plastic tool you must press down on top side of motherboard. :)
[Touch Diamond, MDA Compact IV General] toby_as:
I found an lcd with broken touch panel(lcd is working)...i managed to untape de lcd from touch with hot air...(very hard thing)...the next step si to separate my broken lcd from working touch and hoping to put together with the good lcd....
[Touch Diamond, MDA Compact IV General] diablob:
Its only one big bad thing in HW of Diamond. Connector is better choice for this repair. It will be simple, but reality is this type of connection. I use brazing solder with setting of temperature. Not hot air I have worrying about plastic cover under conecting part.
[Touch Diamond, MDA Compact IV General] toby_as:
Well today i managed to put together the old touch and the "new" lcd panel from another diamond...it not was easy but is working now...and its not perfect but is fully functional :D...now i have 2 diamond (one with wifi and one without wifi)....anyway our discussion is not much helping the others with wifi isues but maybe helping in lcd changing:d

Thanks for your help.
[Touch Diamond, MDA Compact IV General] muhrizky:
i think the title should be changed into lcd problem....
[Touch Diamond, MDA Compact IV General] grmcgee:
I have a Fuze, but have been unable to find an answer to my question in the Raphael forums, so I am trying here, please. My wifi turns on whenever I want it to, and it works great. My problem is that wifi turns on automatically, even when I don't want it to. Currently running Energyrom 21864, but this wifi "with a mind of its own" has occurred on multiple Energyrom versions. I have asked this question in the Energyrom forums and never received a response.

I usually turn wifi off manually to save battery, using an on/off utility or commgr. Then some time later, maybe 10 seconds, maybe 5 minutes, wifi will be on again and scanning for a network, even if I have not touched the phone. I looked at TouchPro (Diamond) Tweak, and I have the "wifi on during standby" switch set to off.

Is there a setting somewhere that tells wifi to start up and start scanning, even if I have manually turned wifi off?

wi-fi problem

Salutare. Am avut probleme cu wi-fi -ul dupa ce am pus un rom preparat. Am tot cautata raspunsuri si nimic.

Deci am un HTC -dimond 1. Din senin, dupa ce am pus un rom preparat wi-fi -ul nu a mai functionat. Pur si simplu nu se mai deschidea, nu incepea sa functioneze. In setings/conections nu aparea wi-fi ci network card.

Cautand o rezolvare am tot citit nimeni nu avea nici o solituie concreta. Ba sa schimbi radio, ba sa il duci la service, etc...

Cineva avea o rezolvare - sa bagi telefonul la congelat. Se pare ca a fost solutia cea buna. Imi luasem gandul ca v-a mai merge wi-fi-ul pana nu-l voi duce la service dar pe 20 dec. am lasat telefonul afara in ger. Pur si simplu wi-fi -ul functioneaza acum. Nu a fost un gest constient ci pur si simplu s-a intamplat. Nu puteam sa tin telefonul in buzunar si l-am scos si l-am lasat afara. Nu va sfatuiesc sa faceti ca mine. Am scris doar pentru a se cunoaste ca este posibil ca frigul sa rezolve unele probleme ale HTC-urilor. Am mai scris si petru ca atunci cand nimeni nu mi-a dat o rezolvare am citit de mi-a venit rau. Treaba cu congelatorul nici nu am luat-o in serios dar se pare ca era reala. Nu pot fi sigur suta la suta ca wi-fi- ul merge acum cu pentru ca am lasat telefonul in ger dar s-a reparat de la sine.
[Touch Diamond, MDA Compact IV General] davipiero:
Someone has definitive fix for this trouble?

Or just a simple explanation, Why is this happen?
[Touch Diamond, MDA Compact IV General] Kutthoat5150:
doesn't seem to be a fix yet, does the Wifi have anything to do with the radio? I recently flashed a new radio with the Gen Y R2 Rom using the MTTY method and that is when the problem first started occurring.
[Touch Diamond, MDA Compact IV General] davipiero:
Me too... Problem started after MTTY procedure....

I've tried 3 different radios with no luck. Including the shipped one.
[Touch Diamond, MDA Compact IV General] ZSX:
I'm sure it is a harware issue. Have flashed every single one of the radios on the radio thread and still cannot get the WiFi to switch on. The wait cursor spins, and checkbox fills with a grey tick, but then clears after that. Oh well.
[Touch Diamond, MDA Compact IV General] Nirak:
Yep, it mostly is a hardware issue (not always). I had the same situation as you, send it in for repair and got it back with a replaced motherboard. Never had any problem with wifi ever since.
[Touch Diamond, MDA Compact IV General] dorimanx:
Wifi wont start Resolve!

Hi,

I have found a way to fix this!

if your Wifi is not damaged (Broken hardware) then this solution will help you to fix the starting problem...

do this:

go to HKLM\ControlPanel\wifi\UIDelayAfterBoot=220

if you dont have this DWORD then create it!

It's will start the WIFI after 220 seconds on boot!

If your full boot takes less then 2 minutes, then you can change to 150

This fixed my problem!!!

Please reply if it solved your problem.

Good luck
[Touch Diamond, MDA Compact IV General] onesterud:
I tried this, but it didnt work. I noticed that in the waiting of the 150 seconds the display were fading to black, but then it went light again when the UIDelayAfterBoot activated. That was all that happend and the problem is still the same.
[Touch Diamond, MDA Compact IV General] minute:
EXTRAORDINARY!!!

What I quote up means that if you freeze your HTC solves the problem... silly right?

As a last resort, last night I put my HTC Touch Diamond in the freezer. -18 degrees Celsius. Left it there all night (22:00 -> 08:00) and in this morning, after the phone wormed up, I started it and SURPRISE!!! The wi-fi antenna start showing up. Till now, nothing showed up, no antenna (instead of [G] in the upper-right corner) no nothing. Just the colored circle in the middle of the display and that is it! But now, I got a big surprise. The wifi antenna started to show, but it vanish very fast. After few unsucsseful starts, the wireless was stable. So, it is a good solution!
[Touch Diamond, MDA Compact IV General] ado90:
hi

i have same problem, wifi wont turn on, and did someone figured how to make it work???

I searched on forum and did not found anything that helped me.

My wifi stop working when I flashed other rom, but I try to back old stock rom and it did not work, and I tried many other roms and radios, and made hard and soft resets but nothing.

Please help, give me something that I can try to make it work.

Thanks

Sorry for bad english
[Touch Diamond, MDA Compact IV General] Nirak:
@ado90

I stumbled on a wifi fix when i had a not working screen and a 'Micro-P' error.

Turned out i had to disassemble the device and reconnect 2 connectors on the main board of the device, once done i also had my wifi back.

I've read alot of threads about the Micro-P error, but i think this is the one that's the most clear about the connectors:

[Google Pixel 4 XL Questions & Answers] johnkristian:
Hi

I've seen that The pixel 4 phones is not advertised with wifi6/802,11ax capability.

However, the snapdragon 855 soc HAS wifi 6 capability.

However, the phones we've seen that use wifi6 today, Like Samsung S10, use a broadcom chip for wifi6. No SD855 phones today uses the socs wifi6 capability.

At the same time, the wifi6 certification program launched more or less at the same time as the pixel 4 launch (one day difference? Don't remember).

Can this just be a certification issue? So the Pixel 4 and other 855 phones will get wifi6 support via the 855SOC via a SW update?

It's REALLY weird that google launched a wifi6 mesh system but their phones won't get it? I REALLY hope wifi6 will be activated on pixel 4 at a later point.

Any ideas?
[Google Pixel 4 XL Questions & Answers] homerunbm33:
Google New mesh system is NOT wifi 6
[Google Pixel 4 XL Questions & Answers] johnkristian:
OK. Anyway, it still doesn't explain the 855 / wifi 6 situation
[Google Pixel 4 XL Questions & Answers] EeZeEpEe:
Just cause the 855 is WiFi 6 capable doesn't mean they'll have it on.
[Google Pixel 4 XL Questions & Answers] johnkristian:
Well, obviously.

But it's still VERY strange.
[Google Pixel 4 XL Questions & Answers] uicnren:
Doesn't seem any more strange to me than the new Nest WiFi not supporting it.

Perhaps, just like 5G, they don't think its worth supporting it at this time.

https://9to5google.com/2019/10/17/pixel-4-5g-reason/
[Google Pixel 4 XL Questions & Answers] kimocoder:
Pixel 4 uses the "Murata SS9709025" WIFI SoC, but we're (NetHunter & Nexmon devs) looking for more information about the chipset.

If someone could post a full "dmesg" and "modinfo wlan" and most logs available really so we may identify this chip.

Btw, Hei John K :)
[Google Pixel 4 XL Questions & Answers] borisSweden:
Arw you

Are you sure? Because the S10 series have several version. Maybe the Exynos uses Broadcomm so there is nothing to port. The 855+ Samsung phones can be possible to port. But there is no dev who wants to deal with that.
[Google Pixel 4 XL Questions & Answers] borisSweden:
Any updates on the mod?
[Google Pixel 4 XL Questions & Answers] V0latyle:
The SD855 also supports 5G, but Pixels didn't support 5G until the Bramble.
[Google Pixel 4 XL Questions & Answers] borisSweden:
Naw, the modem is wrong. For the SD855/855+, Samsung gets shotgun by Qualcomm just to keep them in the US market. But it happens that Samsung uses another modem by Qualcomm or broadcomm. For example, all SD855 phones use the X24 LTE modem while 5G enabled SD855 phones use the x50 Modem. On the issue of sd855 that uses the WCN3990 Wi-Fi chip there is not a single phone with Wi-Fi 6. But wait there is more, some 700 series SOC does use the WC3990 Wi-Fi chip with Wi-Fi 6 but the catch is that that it's on another chip architecture. So porting is a issue, the Qualcomm blobs doesn't like that.

Qualcomm Delivers Premium Wi-Fi Experience with 2x2 11ac Wi-Fi Technology | Qualcomm

Qualcomm Incorporated (NASDAQ: QCOM) through its subsidiary, Qualcomm Technologies, Inc., today announced that a number of leading device and network OEMs are realizing the benefits of Qualcomm Technologies' integrated 2x2 802.11ac Wi-Fi with MU-MIMO

www.qualcomm.com
[Google Pixel 4 XL Questions & Answers] V0latyle:
Makes sense
[Google Pixel 4 XL Questions & Answers] borisSweden:
well after doing research for GNSS Galileo support for the Oneplus 3, it very clear Qualcomm added a back porting fail-safe on all their blobs. I made a suggestion if someone has the time and brain to make it work by taking a 2020 midclass chip from the 600 or 700 series.

You can install DeviceInfo HW to check if the hardware is there for wifi6 before trying out software to make it work. But then you can get to another issue of the right pin not being added, like FM radio for Snapdragon phones, the hardware is there but the OEM didnt pay the 1 cent for adding support.

Edit: WCN3990 is old old old chip used since the SD835. But we can add Bluetooth 5.1 instead.
[Google Pixel 4 XL Questions & Answers] borisSweden:
OK just bought a Wifi-6 router. The phone is WiFi-6 ready which means you can utilise N,AC and Wave2 much better then before with bandsteering. You can port firmware for the WiFi from other SoC using the Fast Connect 6200 series. But if you want Wifi-6E or 7, get the Fast Connect 6900 or 7200.
[Google Pixel 4 XL Questions & Answers] borisSweden:
Incorrect, all Pixels from 2 to 5 used the WCN3990 but it needs to be checked as deviceHWInfo could be bad data. Also there are Snapdragon 400,600,700, 4 gen1, chip series with the same WiFi/BT combo that has real Wifi6 and Bluetooth 5.1 to 5.2. So its just to hunt for a blob that is universal.

Hi. For some reason, I'm not able to make my phone working with any custom ROM but MIUI ones. I tried the guides about flashing the 9.5.9 first, flashing the firmware but still, every time I flash a custom ROM (with flash result 1 in TWRP) and I reboot into the system, the phone keeps rebooting quickly after displaying only the MI logo.

[Xiaomi Mi Mix 3 Questions & Answers] PWn3R:
You MUST FORMAT data partition when you install anything from stock roms. It should boot after you format, and I'm not saying with the rm -rf option in settings if you have TWRP. It must be a full format of data. I know some of the older ROMs used to take many minutes to boot the first time (like up to 10). I am not actively developing for android after they turned on the hardware backed verity states and broke Google Pay with unlocked bootloader, I left android.
