S4 i9505 won´t remember wifi password SOLVED - Galaxy S 4 Q&A, Help & Troubleshooting

hi, i´ve had this issue with my samsung galaxy GT-I9505, after i updated to lollipop I9505XXUHOE3, everytime i reset my phone i had to enter the password again, that happend in my home, my work, every single place, it just won´t remember any wifi network password, i spent several hours looking for a solution, even here i saw some post where they said some WIFI FIX NON-HLOS.bin file would fix the issue, obviously they didnt, at least not for me, also saw dissable the wifi power saving mode with *#0011#, didn´t work, so i used logic, and went to the basics when i first instaled a rom in my first phone, and i remember i read somewhere that had to be a clean instalation, so that is what i did.
1. Enter recovery mode (vol up + home + power)
2. on recovery mode, wipe data/factory reset, and also wipe cache partition.
3. power off
4. enter odin mode (vol down + home + power)
5. load the I9505XXUHOE3 file in odin on my pc and then flash it.
6. VOILA!!! now my phone remembers all wifi passwords that i enter.
if anyone has a doubt i will try to answer it withing my boundries of knowledge, that actually are very short, hope this thread help some people who hadn´t find the solution yet.!

What you have detailed is standard practice, and is what we all already do

How to go from VillainRom to Litening or other Custom Rom :)

I noticed a lot of people getting into boot loops after flashing new roms to their phone. I encountered the same issue and this is the method I used to solve it.
Firstly boot into recovery mode by powering off the phone and then rebooting by holding volume up + power + home. Wipe your cache and user data. Then turn off the phone by holding the power button.
Download stock kernel from here for you firmware and flash this via Odin.
To do this, hold volume down + power + home to boot into download mode, press power up to continue when prompted. Then plug in your USB cord.
Now in Odin, select PDA and browse to where you downloaded the kernel to and select it. Make sure you don't change anything in Odin but do make sure Auto Reboot and F.Reset Time are selected (they should be by default). Click start and wait until this is finished.
You should then be able to flash your new rom onto the phone
I'm not sure that this will work for everyone, but this solution worked for me so I thought I would share it

Unable to reset to factory settings, format memory, flash ROM, etc.

Hi,
My I9100 behaves quite strange.
I am unable to perform factory reset (using code from keypad or command from settings menu) - the phone reboots, goes into recovery mode where I can select wipe data/cache. Doing so has no effect on my phone, after another reboot the I9100 restarts in the same state as before factory reset.
The other thing is that I am unable to format interal memory. After using command from settings menu it says that memory is disconnected, formated, and after that all data (pics, mp3s, etc) are still available.
Also I am unable to flash ROM with any stock (tried KE4 and KE7) or aftermarket (Lightening) software. I tried Odin with and without PIT/Re-partition, also with no effect. The phone boots into previous state nevertheless confirmation in Odin that flashing completed successfully.
And the most aggravating thing is that after I reboot phone I am loosing all the recent data. The phone is booting in the state from before couple of days, with no recent messages etc. Thanks to Google account sync, the mail, calendar and so on re-sync properly, but it is no good solution since pictures, todos etc are gone after reboot.
I believe the thing started to occur after unsuccessful update to Twitter. Tried to do Market cache wipe (as suggested for similar cases to I9000 users), but also to no effect.
Have you any suggestion what else can I do?

Wipe data and cache from recovery then flash a rom, you will lose everything not backed up
There is a guide about howto fix this, search first next time
Sent from my GT-I9100 using XDA Premium App
im sure there is another thread around he with 2 people in it that had the same problem as you, flashing via odin or cwm and then still ending up with the same firmware as pre flash.
i'll see if i can spot it and post it here, i dont know if they got it sorted or not tho.

Mr. veyka perhaps i didn;t drive my point home. Recovery mode is inaccessible. I cant wipe unless i get into recovery. its simple logic. i need to be able to access recovery before i can wipe
@ OP
http://forum.xda-developers.com/showthread.php?t=1178964
That is the thread that i had read which had the same problem as you, i havent read it all but the last few pages tend to lean towards that flash lock go ticked when flashing a ROM via odin.

Hey bud,
If you can get in to download mode then it should be ok, id try 2 things.
Go over to the the original android dev section and grab the CF kernel that was for the firmware installed, boot in to download and flash it via pda in odin, then try recovery again.
If that doesnt work, then download a full firmware from samfirmware and flash the main 3 files (Modem/CSC/Phone) and that should set your phone back to retail fresh.
ofc another reason could be your volume up button is broken

Oh, sorry, missed that, my bad
As said, flash cf root and see if that helps, if not check that your volume up key works within the os, if not flash to stock, and reset flash counter with a jig and send in for repairs.
If it does, cf root comes with an app called cwm manager that will allow you to reboot into recovery that way.

my volume up button works> the reason being you need to press volume up to get into download mode after the Vol down + home + power combo.
There are other people who have had this issue of recovery not available.

GT i9505 keeps reseting at samsung logo

so basicly this happen. i updated my samsung s4 and after the instalation hes gone,,, he keeps restarting at the first samsung logo screen, vibrate then resets , i tryd that volume+ menu + power button and clear chache and factory reset but it kinda did nothing
im new at this android stuff so if someone got any ideas how to help me that would be great !
sorry if there is another post on the forum here with the same problem but i didint see them ,,,
any help would be good ! thanks in advance
type if you need more info
Hi Zarg00
I had the same problem as you a few days ago! Nothing seemed to work, wheter I tried wiping the cache/dalvik chache or doing a factory reset.
With Odin I managed to get it back to life again.
Don't worry, it's easier to repair as you might think. =)
You should have your original Samsung usb cable ready.
Unbricking Samsung Galaxy S4 by Installing the Official Firmware:
If wiping the data/factory reset, and cache partition does not help you, or you are not able to boot into the Android System or ClockworkMod recovery on your Galaxy S4, you can try installing the official firmware on your phone. Read the following guide that will help you find the correct firmware for your Galaxy S4 and install it safely.

Unfortunatly I can't post you the link directly, because my post count isn't high enough.
But try searching on google "droidviews how to unbrick galaxy s4" and it should be the second post with the very well written tutorial.
After you are done with it, your device should work correctly again.
You will lose your recovery and root though.
Good luck and report back, if it worked! :good:
Maybe not the first thing to do but have you tried flashing in the stock rom with odin and then do the updates again?
Sincerely, Joakim
im gettin Official Firmware now, so i think XD its 1.6 gb so its gonna take a while,
i realy hope this is gonna work
In my case i even had to restore the PIT, too. But try just flashing the official firmware before that.
Yeah, downloading the firmware can take a while. You can download the newest Version [I9505XXUBMGA Jelly Bean (4.2.2)] on google drive as well.
Just delete the "_" after https: in the link -> https:_//docs.google.com/file/d/0B7DKa-PuA5IlcVY2MGtMT1ZJMHM/edit
Drive lets you download faster than hotfile.
Its the DBT version though, so you might need to change your language from german to whatever you want at the first start.
But since your galaxy is still able to boot, the chances are really good that it will work well again after you have flashed the official firmware!
im kinda stuck at this
Boot your Galaxy S4 into Android System Recovery mode: hold Volume Up+Home+Power keys together till the screen turns up and the Samsung logo blinks twice. Just as you see a green Android bot, release the Power button but keep Volume Up and Home keys pressed till you see the recovery menu (see below). In recovery mode use the volume keys to scroll and power button to select options:
Go to “wipe data/factory reset” option and wipe it.
Then “wipe cache partition”.
Finally, go to “reboot system now” and select it.
i cant go to recovery mode, i can see little blue letters in upper left corner but phone resets -.-
any hint ?
Which recovery are you using? The "official" recovery did not work very well on my device. It just crashed when I tried to wipe cache partition.
Try flashing CWM Recovery for GT-i9505 with Odin.
uhm im confuzed, can you walk me throu i kinda dont get that "odin" program
dunno what to do with that files you show me :S
Don't worry, it is not that hard. =)
I guess you already flashed the official firmware with Odin, right?
To install cwm recovery follow these steps:
1. Make sure that your device is at least 50% charged
2. Power off your S4. To make sure that it is really off pull out the battery for half a minute and put it back in.
3. Start Odin3 on your PC.
4. Download the recovery file (link in the post I made before ^^) you should choose the one i marked with red in the screenshot below.
5. Okay, you have the recovery file and odin3 ready. In Odin, click the box before "PDA" and than click on "PDA" and choose the file you just downloaded. It should look like in the screenshot below (sorry, that it's in german, but I thought it might help you )
6. Now we have to prepare your Galaxy S4. Press and hold "Volume down" + "home" and then press "Power" to get into download mode. It will ask you, if you are sure. Just press "volume up" once.
7. Connect your phone to your PC with the USB Cable. Odin should recognize your device. Just make sure, that the ID:COM port turns blue.
8. Click on start and wait till your device reboots and Odin shows you the PASS! message. You can disconnect your S4 from the PC now.
9. And now try to get into recovery mode again by pressing "volume up" + "home" + "power". Sometimes you don't even have to press the home button, just try what works best for you. Release the power button as soon as you see the logo, but keep the "volume up" button pressed until you are in recovery mode.
If you can enter recovery mode again (and i'm crossing my fingers, that you can ^^) just continue with the tutorial from droidviews and wipe data/factory reset and after that cache partition.
I hope that helps! :fingers-crossed:
this works, thanks,
i did "Go to “wipe data/factory reset” option and wipe it.
Then “wipe cache partition”.
Finally, go to “reboot system now” and select it."
well that whas kinda the last thing i needed to do, but its still the same,
he shows me Samsung galaxy s4 gt - i9505 logo and keeps reseting ,,,
so this didint fix my problem
Damn.
Did you also flash the PIT files? I would do the whole process again, but this time follow "How to unbrick S4 by Flashing Stock Firmware and PIT File".
If that doesn't work as well, I guess it is some hardware error. The good thing is, that you did not lose any warranties by following the tutorials and you can return your phone to the shop and claim a repair.
so basicly i did all over again its still the same phone keeps resetting
but in recovery mode i noticed after i do this
"Go to “wipe data/factory reset” option and wipe it.
Then “wipe cache partition”.
Finally, go to “reboot system now” and select it."
when i want to reboot it says " Root access is missing. Root device ? "
basicly there are lots of
NO
NO
NO
NO
YES - Root device (/system/xbin/su)
i hope this helps you so you can help me :S

aaaaannnnnddd nothing, it resets
im back at the beginning ,,,, he whas working fine for about 10 min then he just shuts down and resets all the time ,,,,
Hey Zarg00 =)
Did you restore the PIT file as well this time? You phone shows a really strange behavior. O__O
I have found a thread here, which might hopefully help you [Guide] How to unbrick your phone.
Sometimes flashing files with Odin won't work the first time and you have to try it multiple times.
If that all doesn't work, then I guess it is not a software but an hardware issue. :/
well i made it work, and its fine now, but it restarts sometimes ,,,
also Kies cant see my phone, its stuck on connecting ,,,, i can browse it throu My Computer i see it there
Cool! It finally works now? Did you do anything different or just the steps from the tutorial again?
Kies never really worked for me. Sometimes it didn't recognized my device at all.

[Q] Factory Reset get stuck on Downloading Do not turn off...

Hello Folks... I want to make a Factory reset on my SGH-i337 ATT Galaxy S4, but I am getting troubles when doing in either way
1)System Settings > Accounts> Backup and reset or buy 2)pressing Vol Up + Home + Power . On the first method when I confirm the Delete All data the phone try to restart and it got the Downloading ... screen also when trying the 2nd method the same issue happens.
I have looked every where and can't find something a like.
Also in the tiny letters says the could not do normal boot: Odin Mode, Product Name Current Binary Samsung Official etc.
But if I do a Vol Down + Home + Power I can go to a screen that say Volume up to Continue or Volume Down to Restart and I choose the second and my phone restart without any issues. But without the Factory reset.
I gave Safestrap installed but no Slot roms yet

You did something wrong and screwed up your stock recovery. You need to odin back to MF3 and try again (assuming you are on MF3 to begin with). Make sure you read EVERYTHING before you try it again though. You can search the forum to find out how to use ODIN to get back to stock MF3. There is a thread or two about it in the General and Q&A sections. Good luck.
While you are at it, you should probably go a head and read all of the "pinned" threads in the general and Q&A sections as well.
All questions and help issues go in Q&A and Help section
Thread moved
Thanks

I experienced the same problem too. Follow these steps:
1) Restart your phone and boot into Safestrap.
2) Make sure the slot selected in "Boot Options" is the "Stock Rom"
3) Go back to the main menu of Safestrap and click "Wipe"
4) Then "Swipe to Factory Reset"
5) Once reset reboot your phone and you should be factory reset.
Good Luck :fingers-crossed:

messed up trying to root

MODEL: SM-G900V
hello i messed up my phone by trying to root it, i used a random md5 that someone online said would root it with odin under "PDA" and now my phone will only load into recovery mode
i tried wipe data/factory reset and clear cache neither of them did anything
i tried doing it through kies and doing Firmware Upgrade And Initialisation but i couldn't even get my phone to connect to kies OR my laptop except it attempting to while the phone was starting up,
and when i tried to enter my S/N after my model number it continuously told me it was wrong
and i've tried loading a normal rom into my phone through odin and i couldnt because like i said, it'll only load into recovery mode, not bootloader..
but i think at first it could load into bootloader, but now it can't? it's hard to remember since ive tried so many different things in a very short time
if anyone has any idea how to help me, i'd appreciate it so much! please try to write simply if you can because i am a noob,
You don't need to go into bootloader. You should start with download mode which is accessible by holding vol dn home power.
If that doesn't show up, try taking off battery for a short period of time. If it boots into download mode your good to go.

ah it worked ty!! (incase any1 is here needing help later) the complete fix for it was taking out the battery for like an hour, holding down volume+power+home, plugging it into pc, using Odin3 and a clean rom of my version from sammobile.com, then pressing up volume+power+home again
