[Q] How do I install the original firmwire?

I've downloaded the original firmwire, and Flashtool. When I'm in flashmode, I get the message that I need to turn my phone off, and press the back button. When I'm pressing the back button and plugging in the USB cable, the sound of the USB is like it's not getting connected or something. It's a sound with the same tone, that repeats 3 times..
I got the MIUI Rom, but I need to change it back to the original, because of a: Sim Network Unlock Pin.. I think it's an error, so at least I have to go to the original firmwire to check, but I can't because the flashmode don't work.
Anyone got any idea what to do? I'm really desperate..
Thanks in advance !

Nvm, got it working. Close all my threads if it's possible

Does anyone know why I get: "Sim Network Unlock Pin" when I'm using MIUI rom?
When using the original firmwire, there was no problem.

How to flash back with stock recovery can you please explain?

Hi prashanth667
I've got exactly the same issue.
Can you give me all references in your system/about device?
Did you only flash CF auto root before the issue appearing?
What was your android version?

Flash stock firmware.

That doesn't work UtkarshGupta. I've tried several stock firmwares.
There is another big thread dealing whith this issue. Maybe you can try solutions over there.
But please prashanth667, did you only root with CF-root before the wifi issue?

How to do that ?

Hello m8, I hope that your problem is as simple as mine, but first what kind of router do you have? Tplink by mistake?
Oddly enough you said you were connected... thus I doubt it is you phone.
The problem wasn't phone itself but the router... try resseting the router.
Another issue my coworker had is to have his router accept wifi connections allowed by mac address...I do not believe this is your problem but try it anyway.
To confort you sometimes after note factory reset I get the same issue and always soved it by ressetin my own router. It hap po ened on different roms thus...

Go to normal dialer screen
type *#0011#
this should take you to the service menu
now press the menu button (lower left, below screen)
select Wifi submenu
In here there is an option for wifi power saving. Turn it off.
Exit the menu
Try your wifi now.

I used to have this problem too, but suddenly fixed itself when installing a new ROM.

I have the exact problem with my new Xperia Z with the official firmware. The phone keep trying turning on wifi, but still off and Bluetooth also dead as well. No permanat solution so far. I manage to do a temp fix by completely drain the battery until completely dead with no indicator even when pressing the power button and then do a full charge until 100%. But the phone crashes again after few mins of wifi connection, and them wifi die again. However, this does not work all the time. So good luck, I think is faulty hardware anyway.

Either wait for an uptade from Sony (lol) or try to flash a stock rom if your BL is unlocked

Forgot my screen lock pattern! Xperia ZL help !

I have a Xperia ZL and recently I changed the screen lock pattern but then I forgot it ! After 5 tries it asks me my gmail but I do not have a gmail. I use a hotmail email associated to google to acess youtube and google play.
So I starting looking for a solution: bypass the screenlock or hard reset but did not get a solution until now.
Tried this process:
button volume+ and button power
button volume- and button power
button volume+ and - and button power
pressing yellow 'off' button in the back of the cell phone for 15 seconds (3 vibrations) and nothing.
Tried hard reset by PC Companion too, but I got this message:
'There is no software available for your device.
Details: Sony Update Engine doesn't have software available for your device.
Troubleshooting: Please Try Again Later
If you still encounter problems, please report issues to Sony Mobile and provide the error above'
I'm looking for an answer! I've found some rooting and flashing guides to change the firmware but I prefer an easier and safe solution ! But if there's not.. I can try this way. Thanks !
Edit1: I was trying to unlock bootloader to flash stock rom after but USB debugging is disabled (And my screen is locked, can't enable it).. what can I do?

U can try flashtool

+1 for FlashTool. If you don't care about retaining your data, just download and flash an FTF. You don't need a USB debugging for that. As long as your phone can go into flash mode (device off -> hold Vol. Down -> plug in USB), you are good.
BTW, aren't you supposed to have a PIN backup option when using a pattern? I thought so, but can't recall for sure, as I don't use pattern unlock...

Is there a way you can go back to KK? If you're getting sound then it's the Lollipop ROM, if not, your phone needs work!

Try safe mode to verify if sound is working or not.
1. press & hold the device Power button
2. power off options will appear.
3. on touch screen, hold power off untill, reboot to safe mode dialogue appears, then click OK.
4. when boot done, try playing any audio/mp3 file,
5. if working well in safe mode, then some 3rd party app is causing trouble, find it & update or uninstall it.
6. if in safe mode, you can't hear sound, thats bcoz lollipop update went wrong bcoz of you have update on root access.
7. To exit safe mode, turn your device off and on again. thats all!
