Fix for no WiFi connection when Sim is active

I imported my HTC first from America and a major problem I found was that the WiFi didn't work. I was prepared to return my phone citing hardware problems but I waited and instead tried to find a solution by myself. I finally got it working.
This thread is for all others who have the same problem that I did.
Temporary Fix
1) unlock boot loader, root and do s-off
2) you must be running ruu 1.08.502.1
3) make your way to http://forum.xda-developers.com/showthread.php?t=1445766
There you can see many people have the similar problem.
Follow the instructions and install the app by the OP
(Make sure push the wifix app in the /system/app folder) verify the app is working properly by dialing the code given in the other thread. Open the wifix manager and set code to 'us'
4) if you read the thread you will see the app works for android 4.0 but most users having jellybean report it as not working
5) try the steps of post #250 (I used the AT&T code)
6) now whenever you restart make sure WiFi is switched OFF before reboot. When your phone boots up again make sure you're getting network signals, then open the market changer app and select AT&T. Then turn on the WiFi.
7) your Wi-Fi can see and connect to access points!

UPDATE 13/5/2014
WIFI NOW WORKS 100%
Ok with a lot of digging around I finally managed to fix my wifi. Sim inserted or not, wifi on/off at reboot or whatever, it doesn't matter because wifi always works. And no need for any annoying apps to run at boot!
For this method I had to endure a lot of headaches -_-
Had to search the whole internet, learn about adb commands, logcat, compiling .jar files etc
1) unlocked bootloader, rooted , s-off and running deodexed 1.08.502.4 . I did this on a clean install with no wifix/wifi codes/market unlocker
2)
First you have to learn how to compile and extract jar files:
http://forum.xda-developers.com/showthread.php?t=2251719
You just have to read "1. How to Decompile and Recompile *.jar file or classes.dex"
3) THIS STEP NO LONGER NEEDED *Removed*
4)
You need to read this too:
http://forum.xda-developers.com/showthread.php?t=2628707
modify "framework2.jar" which is present in /system/framework
And after you have decompiled, open on your PC
classout/com/android/internal/telephony/MccTable.smali
recompile framework2.jar , put it back in androids /system/framework and set permissions to Rw-r-r
Now we have to modify another file
This time its the /system/framework/framework.jar
after decompiling open in PC : classout/com/android/net/wifi/WifiStateMachine.smali
and edit as per the second post in the link, recompile and paste it back into system/framework,set permissions to Rw-r-r
Note : its best to use adb commands to copy and paste the framework files from android to PC and vice versa
(namely adb pull and adb push)
then do some extra steps:
"Extra step 1
click on "/system/build.prop" and open in any text editor(on android);
seek line
ro.product.locale.region=GB
and change GB to US; confirm OK for save file.
mount /system R
Extra step 2
because of first boots, in Settings database is written our country code,
which should be US.
for this: install "Sqlite Editor" (android app), run, grant ROOT access. after program finds
& lists databases, look for & open "Settings Storage" > settings.db > global:
find "wifi_country_code", select it and press menu button > Edit Record;
change value to US and press "save" "
Reboot.
Congrats!! Wifi now works no matter what you do!
(as long as your wifi is on channels 1-11 , if youre on channel 12 or 13 then I think you need to change wifi country code to an european country instead of 'us')
Note: Be sure to thank the original authors in the threads i've linked.
As usual, do these steps at your own risk, I am not responsible for your bricked devices. Do report if it worked for you.
Also I know i've made quite a bit of mess. Do tell if you have any problems with the steps. I was thinking about posting my own framework.jar and framework2.jar but i'm not sure if they are safe to share or they contain private data. I'll need to confirm from someone.

Walikum assalam,
Did you mean this rom worked with HTC First aka MYST_UL ??? Thanks!

No wifi and now sign-in loop.

I'm stock running 5.1.1, my wifi stopped working after install. I did a factory reset, cache wipe etc.
This didn't work and now when I start the device it asks for the language, wifi connection (Which doesn't work) and ask me to login with a google account previously synced with the device. So, I put my details in and it boots me back to the wifi connection screen.
I haven't changed my google password and as I'm stuck in the no wifi-loop. I can't access my settings, which means I can't access USB debugging to install 5.0.
My phone is essentially a brick? :crying:

In my N6 there is a folder 'persist/wifi' and that folder is empty.
When you have a data connection at your telecom provider you can go to the play store and install a WiFi fix app.
When you are rooted you can also change/add in build.prop the value of WiFi.supplicant_scan_interval.
When it is not there add it with the app 'build prop editor.

MIUI Global 7.2.4.0.0 uses A LOT of RAM. (?)

Hello. Couldn't find a post related to this. I'm not a lazy browser, been on XDA for many years through many phones. Just haven't had the need for a user account until now.
I see the 7.2.4.0.0 version is removed from MIUI websites and i can think of a few reasons already.
Does anyone else have this problem too? I have the 3GB version and normally start out with 1.7gb RAM after a boot. Gradually over the day (even after closing apps) it goes slowly down to 200mb and i have to do a reboot.
Or Does anyone have the 6.5.30 version and could tell if it uses up the RAM over time?
Sincerely
John

You have a fake rom. 7.2.4.0.0 is not an official MIUI rom and newer was. 7.2.4.0 is an official rom.
You should flash the official rom.

You are on an un-official modefied version.
The fake version is 7.2.4.0.0 <- your version.
The real official and supported by Xiaomi version is 7.2.4.0

Hi,
Hope I can get some help. I recently just picked up a unit and am on 7.2.4.0.0. Realised it was a fake rom but I seem to have trouble flashing the global rom or the china stable rom. Believe my bootloader is locked at this point and have applied through the unlock miui website but that will take at least 10 days or more to get the SMS.
Frustratingly, I have seen some solutions on the miui forum and there was one proposed solution, of which many were finding success, that includes booting to recovery mode and then hitting shift + [flash] when connected to the Chinese miPCsuite. My update only goes by to mid 50% levels and then its stuck on for several hours! Is this a USBC to USB port incompatibility issue (if it was it wouldn't have recognized the phone right?) or is my phone just beyond saving ? At this point, im not confident in using other solutions as they look highly technical and some have highlighted that their phone has bricked in doing so.
Appreciate any advice! thanks. PLEASE HELP!

if you already tried the simple steps as stated then there are no more simpl steps left.
Do an EDL flash and make sure you clear all, and be aware that most Mi flash stuff works best on Windows 64Bit.

What he said, download the latest, both files can be obtained HERE
-MiFlash tool - step 1
-official fastboot rom - step 2
install the MiFlash tool
extract the downloaded rom (tgz) then extract the output file (tar) > make sure you copy the path of the directory where you see all the files like flash_all flash_all_lock etc..
reboot your phone into fastboot mode (you can access this by turning off your phone, hold vol - and power)
make sure you have adb on your pc
type this: the first line is optional to see if the phone is recognized.
Code:
fastboot devices
fastboot oem edl
edit: I should mention, do not panic, the screen of the device will turn black but will still remain on.
launch the MiFlash tool
Click on Refresh, you will see a device right now in the list called COM (some number) >>>> it will be ticked
Paste the copied directory path into the white... uhh search bar thingy . or just click Browse and select the appropriate path.
Click Flash
edit: once done, simply unplug your phone and restart it by pressing the power button.
That should be all

Thanks for the reply! Before proceeding, I actually received the SMS to unlock the bootloader but im still at work so I cant go back and attempt the unlock. So just trying to manage my expectations here.
Is it safe to assume that all I need to do now is log in to the unlock tool by miui and unlock? because im still on 7.2.4.0.0 (the unofficial discontinued rom) and I have no way of flashing it to any other roms. My last attempt last night was again, stuck at 52% after a nights worth of wait! TT

Thanks for the help. I will attempt this as a last resort. I just received the SMS to unlock my bootloader. Hopefully its as simple as logging in and unlocking so I can get rid of this pesky 7.2.4.0.0 supposed "Global" rom.

i have successfully flashed to global rom!!! but now i have no audio coming from the speakers!!!! is it just my luck!!!??? and after reflashing again.. its completely dead.. its goes into the sign in to miui welcome page and just goes insane.. like to the point where i cant even select options and and random menu sounds keep coming up.. cant even turn off i had to reboot to fastboot.. is a goner? sighs..

7.2.4.0.0 to Resurrection Remix (CM13)
- unlock bootloader
- flash TWRP with fastboot
- install Resurrection Remix
- install GApps
- reboot, now it's say Google play stopped.
- go back to TWRP
- wipe data
- reboot and everything is working

Flashlight don't work - How to test if it is broken

Hi, first of all, sorry for my bad english.
I hope you understand
I've installed LineageOS 14.1 and all work's great
Then I've installed a new nightly and the camera led flash didn't work anymore.
Not as flashlight and also not as camera flash.
So I did a "factory reset" and installed the first LineageOS build.
The LED still doesn't work.
I wan't to test the Hardware if the LED is broken.
I used following code to open service menu but nothing happens. *#*#197328640#*#*
The entered code dissapear and that's it.
How can I test the Hardware? some tipps to reactivate the LED?
Thanks a lot

Noone?
I need some help, please.
How can I test the Flashlight to find out whats wrong. Is it a soft- or a hardware issue?

Factory reset is not enough. Recommended is clean install, wipe at least system, cache and dalvik, then flash previous ROM. If it still doesn't work, flash KDZ.

First of all, thank you.
With "factory reset" I mean I made the following:
Code:
1. Boot into TWRP
2. choose wipe
3. choose advanced wipe
4. select: Dalvik/ART Cache
System
Data
Internal Storage
Cache
5. swipe to wipe
6. flash previous ROM
So it doesn't work. How can I flash KDZ?
The same way like LIneageOS?

No its different look around on xda for this device flashing kdz and you'll find it.

If installed D40520a_00.kdz
Flashlight still does't work. So it seems to be broken :crying:

Yeah it probably is.

Hey there. Your flashlight is not broken. Trying adding the widget to your lock screen. Or if you want to test type this in your dialer 3845#*405# and a hidden menu will appear from where you can test the features of your device. But if you reboot your phone they reset. I hope this helps you.

Hi there.
You're right.
I've flashed the new LineagoOS nightly and the Flaslight turns on for about 1 or 2 seconds and then turn out.
This happens every time i've tested it.
The code 3845#*405# doesn't work.
I see a message saying "USSD code running". That quickly disappears and then nothings happens.
It seems that I can't add the flashlight widget to lock screen.
any suggestions how I get the flashlight work?

I've flashed the new LineagoOS nightly and the Flaslight turns on for about 1 or 2 seconds and then turn out.
This happens every time i've tested it.
The code 3845#*405# doesn't work.
I see a message saying "USSD code running". That quickly disappears and then nothings happens.
It seems that I can't add the flashlight widget to lock screen.
any suggestions how I get the flashlight work?

Hey there the code won't work in custom roms. It is only for stock roms.It opens hidden menu. Custom ROMs take the advantage of your phone while it mat offer you a faster phone.Please revert back to stock ROM. Ik stock ROMs are slow.But it is much better to stay with stock ROMs with root and custom recovery and xposed.Check flash light once you flash stock recovery.
Hope this helps ?

First of all: Thanks a lot.

What means xposed? Some kind of app?
I've flashed D40520a_00.kdz ago but Flashlight also didn't work.
It "works" since I've flashed ne nightly...
If I flashed the stock rom all Preferences would be reset, right?
So why did flashlight not worked if I installed D40520a_00.kdz?

Hey take a backup of your internal storage.Then in Lg flash tool do a csc flash.Flash correct kdz file.
Try some Google play apps for turning on flashlight

I've tested every menupoint and I found nothing.
With the stockrom I have no Torchlight symbol in quick settings (when you move from the top to the bottom where you can activate wlan, bluetooth etc.)
I add a torchlight widget to the homescreen. It turns on for about 2 seconds then turns off if I activate it.
The SOS-function works. Lollipop or KitKat stock. always the same result.
Is it possible to flash the complete smartphone.
It seems like there's a progamming block or some kind of settings that's wrong and that won't reseted with stockrom flash.

Download flashlight from playstore and test

it is always the same with every app.
The LED works for about 1 second than turns off.
Flickering works at all.

Try contacting lg service centre for a possible fix.Try flashing a bootstack or a custom kernel.I know they are not related to flash light but still trying is not bad at all.

Question Help! Whatsapp bug on Redmi note 10 pro

Good day. Please I need assistance.
I have an issue while using Whatsapp on Redmi note 10 pro (128GB/8GB). When ever I type a message, it doesn't get delivered. That is, the clock sign is there. No single or double check . Whenever I exist the app then open again, the message will deliver.
Every other thing is running smoothly, status are coming in, and no lag. But whenever I send a message it doesn't get delivered until I exist nd open the app again. If I type another message, it doesn't send untill I exit and open the app again. Sometimes Whatsapp will function normally and then randomly this problem kicks in.
Whatsapp version: lastest as the time of this Post.
Android version: 12
Miui: 13.0.8 (stable)
Please help me

2. if you have new update in playstore try updating and try...
3. clear cache and app data (clears all your files) and try again
4. or uninstall and reinstall whatsapp and try again...

Thank you so much for your response.
I've been facing this problem ever since I bought the device on July 18th, 2022.
I'm using 4G, network is stable.
I've updated to the lastest version of Whatsapp .
I also cleared app data, but yet the problem still persist

See if it also happens with Wifi. It could be MIUI power saving enabled in settings. Make sure you have no power saving applied under whatsapp in apps.

fine.. i dont find any exact problem.... i hav few questions...
1. Hav you tried using wifi connection...? still the same?
2. what about "restrict data usage" and "baground data" status?
3. hav u try uninstalling app?
4. Try changing ur keyboard app (i know its not related to this. But , i m asking u to try once)
5. what about other Messengers (like telegram) status?
i dont this is a big issue... but
(if nothing is works , may be try flashing again- no other way...)
Flashing means - factory reset(wipe data) from recovery (if you are in stock rom with locked bootloader)

Uninstall Whatsapp, Restrart the phone reinstall whatsapp again. Might work. ...

Thank you for your assistance. Sorry for giving a feedback this late cause it took some time to follow the tips you shared.
1. I tried using WiFi. It didn't work. Other messengers like telegram and Instagram works normal in sending messages even on 4G mobile data.
2. Whatsapp isn't on restricted Data and it's allowed to use data on background.
3. I've uninstalled the app in the past before coming here for help and it didn't work. Even when I updated The app few days ago, it still didn't work.
4. I changed keyboard to swift keyboard from play store. It still didn't work.
I've also factory reset the phone in the past before coming here for assistance. It still didn't work.
I use two Whatsapp. Kindly Checkout the screenshot from main Whatsapp which gets 500 views on status. The messages doesn't get delivered. Check out the second Whatsapp which sends messages freely.
I feel like my phone is cursed.

I disabled every possible setting that could be the cause under MIUI but the problem continues. I allowed all permission and allowed background data. But no good result

I think you use a whatsapp modded right? If yes, you have to disable privacy mod in wz settings (like last seen, blue ticks etc.) and re-enable it. It's a bug with any version modded of whatsapp.

No I dont use mod Whatsapp. I use the official Whatsapp from Google play store. I searched in another community and discovered that some Redmi users also experience this but Xiaomi doesn't seem to care.

I managed to disable MIUI optimization in MIUI 13.0.12
All apps permission has been reset to default.
Now trying to observe Whatsapp to see if the problem is resolved.

The issue still persistent. Please help

....you have to enable all permissions in rightmanagement of whatsapp app. Then restart your phone.

I had this issue for a while. Resolved itself.

Thanks to everyone who provided support. I messaged Whatsapp about the issue and the asked me to update to latest version of WhatsApp. I did and everything worked out fine . But the funniest thing is that I've been updating to latest versions but it was never resolved. But when I emailed them and they responded, and I did what they asked me to do then everything went back to normal.
