One wifi network does not work anymore

Hej,

I got a very strange issue: Since the new year I cannot connect to the wifi at my work. It always says "Authentification failed" This only happens to my device. And only on this specific wifi. Any other wifi is working properly. I checked for MAC Filter settings in the wifi, checked if there are enough free IPs, etc.

And I am 100% sure to put in the correct password. I tried different devices and they worked all fine.

Using CM 11.0-InstallerXNPQ32P

I am thankful for any hint to find the reason to this because it is really strange.
[Galaxy S 4 Q&A, Help & Troubleshooting] pjilka:
I think I've bricked my phone. Please help.

So recently I updated my ROM to a lollipop version (details below)

I wanted to update the modem/bootloader due to battery issues.

I found the latest version for my phone is I9505XXUGNJ3. So I proceeded to this post - http://xdaforums.com/showpost.php?p=50965837&postcount=2627 to find the modem and bootloader.

I managed to flash the modem via Odin perfectly fine, but the bootloader failed and in the process messed up recovery. When I tried to boot my phone. I received a message saying "system software not authorized by samsung has been found on your phone".

I restarted the phone and tried to go into recovery, but to no avail.

I've since then tried to flash the official stock firmware using this thread - http://xdaforums.com/showthread.php?t=2265477 but that kept on failing also.

I followed instructions on here, attempted flashing many times, using different ports. Was using an official Samsung cable, didn't want to risk using one of the cheaper ones I had available.

I tried updating the PIT file, which was the only thing that worked successfully via Odin.

After which I tried flashing the stock firmware, but it still failed.

Currently when I load up the phone it automatically goes into Odin Mode, I get the image in the middle showing a phone connecting to a PC with a giant warning sign in the middle. And it says "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again"

In the top corner I have the following details:

So, You flashed stock firmware + pit file.

[Galaxy S 4 Q&A, Help & Troubleshooting] Tim-2.0:
Yes, flashed the pit file multiple times coinciding with stock firmware, custom ROMs and also by itself. The stock firmware is 4.4.2. After flashing the stock firmware the phone boots up as it should.. During operation seemed a little buggy though, however I didn't use it very much.
[Galaxy S 4 Q&A, Help & Troubleshooting] malybru:
You only need to flash the pit file once.

So , you can get back to JB , and your phone does work.

It's only when you try to install certain custom ROMS that it fails?

I take it that you did wipe cache and data after the firmware flash?

And you did re-install a custom recovery before flashing the custom ROM?

:)
[Galaxy S 4 Q&A, Help & Troubleshooting] Tim-2.0:
You're exactly right, stock JB works and only certain custom ROMs fail.. EG CM 10/11/12, PAC man ROM and slimkat (That I've tested..) 4.3 custom ROMs seem to work along with 5.0.

Everything is always thoroughly wiped prior, then I flash Philz before flashing the custom ROM through recovery (Philz)
[Galaxy S 4 Q&A, Help & Troubleshooting] Soufiansky:
You can flash a 4.3 ? So you did a downgrade without issues ? :eek:
[Galaxy S 4 Q&A, Help & Troubleshooting] malybru:
Have you read through the first posts carefully?

Some ROMS recommend a certain custom recovery.

It may be that TWRP or CWM are required.

Although , I cannot see a reason for this , because I have only ever used PhilZ.

:confused:
[Galaxy S 4 Q&A, Help & Troubleshooting] Tim-2.0:
Yep, somewhere along my travels I got a boring stock prerooted 4.3 google edition to work, however that's it. I want KitKat goodness!
[Galaxy S 4 Q&A, Help & Troubleshooting] Soufiansky:
Ah a custom rom , i thought it's a stock firmware :D

Look , do you wait enough when you flash the roms ? You should wait 5minutes in the boot logo.

Try a custom rom based on TW ( goldfinger or Note 4 rom )
[Galaxy S 4 Q&A, Help & Troubleshooting] Tim-2.0:
I feel that in this case the recovery is irrelevant as I have also tried the CM installer which forces the CWM recovery on to the phone and flashes CM for you which doesn't even work.. Also I have been using a combination of Philz and CWM recoveries throughout this entire process.

I have just noticed that somewhere along the line I have been getting confused.. JB seems to flash alright, given the 1 custom ROM that I have tried - Unless CM 10 is JB? However KitKat is what I am ultimately after (4.4.4).. I can flash a 4.4.2 stock KitKat, but unfortunately that's it. Every custom 4.4.2 / 4.4.4 that I have tried flashes fine, but hangs on bootlogo.

---------- Post added at 12:18 PM ---------- Previous post was at 12:08 PM ----------

I always wait at least 10mins, but usually up to about 20 on the bootlogo.. Sometimes longer! Out of pure hope I even left it booting over night the other day but was severely disappointed when I awoke the next morning. haha
[Galaxy S 4 Q&A, Help & Troubleshooting] malybru:

I know it is a different device, but similar. Being that I was on 5.0 when I upgraded my bootloader, could it be that 4.4.2 and 4.4.4 cannot be recognised? I was running stock 4.4.2 today and it was EXTREMELY buggy.. Perhaps my flashing of 4.3 ROMs is just luck, or they simply may not be "blacklisted" Hmmmz :banghead:
[Galaxy S 4 Q&A, Help & Troubleshooting] Soufiansky:
I think something is going wrong with your device really , because even with the hard way nothing solved the issue :D

Custom roms does not upgrade the bootloader , but the stock does . Actually there is no 5.0 bootloader for the s4 , it mean you can have an old bootloader or the last one ( for kitkat )

Try to flash a stock rom then flash a new fresh bootlader with it . Do a factory reset + wipe before and after you flash your device to make it very clean :)
[Galaxy S 4 Q&A, Help & Troubleshooting] pjilka:
A few questions.

Does the firmware provided by Samsung for example, come with a bootloader, modem, etc.?

After many attempts of trying to flash the firmware, I've very nearly given up.

Are there any other steps I can take prior to flashing the firmware to give it a better chance of working?

For e.g. could I put on some recovery s/w and try and wipe everything? Or make use of Kies somehow?
[Galaxy S 4 Q&A, Help & Troubleshooting] Soufiansky:
You can flash just the bootloader if you want to change it .

And from what i know , i think it change the bootloader too. Malybru can affirm to you :)
[Galaxy S 4 Q&A, Help & Troubleshooting] Tim-2.0:
I know there is no 5.0 bootloader, however I manually "upgraded" my bootloader (without knowing exactly what I was doing) while I was running 5.0 and tripped Knox.. So technically I think the bootloader now only recognises 5.0 ROMs, therefore why I cannot properly downgrade - As the new bootloaders are locked.

Bootloader: I9505XXUFNAD

Hi,

Stock firmware flashes stock ROM/kernel/recovery.

Bootloaders and modems can be flashed separately , if you so wish.

To increase your chances of success , make sure all instances of kies are removed before flashing.

Check HERE for a full troubleshooting list , and a choice of firmwares.

Remember , if you have the new bootloader , the firmware you flash must be the same version , or a later one , that the one currently on your phone

I am not sure what you mean.

There are only 2 bootloaders:

1. without knox (old one )

2. with knox ( new one)

By the sound of it , you must have new bootloader , with knox flag triggered( 0x1 )

You must be talking about something else , but I am not sure what

Either way , unless you actually want to use knox ( for work , or something) , there is no other difference that I know of.

Hello,

This is the first time for me to post about something on xda but I'm pretty familiar with flashing custom roms, custom recoveries, root, flashing stock via odin and so on. There is however a thing I would like to find out from more experienced users because I want to be ready for when the 5.0 update will be released.

I now have i9505 4.4.2 stock/ no root, and TWRP 2.8 installed. Obviously I can't OTA with this configuration when 5.0 will hit.

So I was wondering how I could update to official 5.0 and keep all my apps and data and system settings.

I was thinking I could:

1. Backup my current stock 4.4.2 rom using TWRP.

2. Then flash 5.0 stock via odin/ or flash 4.4.2 via odin and then OTA to 5.0 ( which is better ???)

So now I am on 5.0 all stock, nothing else installed.

3. Then install TWRP via odin again.

4. And finally use TWRP to restore only the DATA partition from my 4.4.2 backup

Will this work and restore apps and their data + system settings ?

Thank you for your answers !

Hi,

You are better off saving with Titanium Backup.

Do as you said to get back to stock.

Make sure you flash a stock firmware that is the same or later than you currently have on your phone.
