[Galaxy S 4 General] knck out:
Just tried to reflash stock with pit using 3.09 and still experiencing the "Device will reboot" once i turn on the phone

Also when i go into recovery mode i see an error on the bottom saying "E:failed to mount /efs (invalid arguement)"

could this potentially be the cause of my problem?
[Galaxy S 4 General] samersh72:
hmmm... you have a problem in efs partition. do you have a backup for it?
[Galaxy S 4 General] knck out:
Unfortunately...no

Is there any other way i can fix it?
[Galaxy S 4 General] Remember Me?:
No,only service center
[Galaxy S 4 General] samersh72:
this fix will let your phone reboot, but if you dont have an efs backup, i guess you will not have signal.

No, only if you have a efs backup

Alright thanks for all your help man, one last question though, I bought this device used so I was wondering if there is anyway I can check if the device still has warranty on it?

I know samsung gives their devices a one year warranty but i don't know when the original owner bought the device

tried that again and still the apps where crashing, its seems to be all the google apps that are crashing along with touchwiz home. Unless its a bad download of firmware. But im lost.

Just something that might do it do i have to reinstall stock recovery to wipe/format data before flashing back to stock, or can it be any recovery

wifi nto working and keyboard stop working popup every 5sec

Hi guys

I'm having a problem i can't resolve. I had 4.2.2 on my unlocked gt9505 and tried this update because i had root and couldnt get OTA updates.

After doing everything and starting the phone in 4.4.2, i have no wifi and i have "keyboard stopped working" popup every like 5 secs.

Tried flashing with international and leaked versions with no changes.

Any suggestions?

Thanks!!

Hi,

Which firmware did you flash?

:)
[Galaxy S 4 General] cannondalee:
Hey there!

I tried

Open European (4.4.2)

then

Leaked stock 4.4.2

I9505XXUFNA5_I9505OXAFNA5_OXA.zip

Both same problem :(.
[Galaxy S 4 General] malybru:
Hi,

Try the German one:

I9505XXUFNB8_I9505OXAFNB8_DBT

Make sure you wipe data and cache before and after flashing.

If you have problems with wifi after flashing the latest rom, then flash again but this time first switch off the phone and then start in flashmode holding the buttons. then it will work.

[Galaxy S 4 General] busbyeie:
Hi I got what you will probably think of as a noob question as I am a noob. I am confused as to which firmware I can use after reading so many things.

I have a GT-I9505 which is meant to be unlocked, can't tell as I don't have the new micro sim yet. it is rooted using saferoot and has TWRP installed. The firmware it is on at the moment is I9505XXUEMK9 and I believe it is an official samsung firmware. I have done a custom backup of everything.

If I wanted to change it to a custom rom and then flash it at a later date back to stock could I use I9505XXUENAA_I9505YXXENA7_BTU or would I need to use the I9505XXUEMK9_I9505EVREMK1_EVR.zip 1.43 GB as I have a Virgin sim ?

Also not that I believe that it makes any difference but KNOX is tripped, just thought I would mention it.

Info of my phone from mskip's toolkit in the attached file.

Any help with this would be much appreciated. :D

It didnt fix wifi. I'm very worried now about the crashing , Is there any chance i have bricked permently my phone?
[Galaxy S 4 General] malybru:
Hi,

Phone is not bricked.

What was the latest firmware that you flashed?

:)
[Galaxy S 4 General] malybru:
Hi,

You are on a 4.3 firmware.

If you want to keep it on 4.3 , flash any 4.3 firmware .

It does not matter which one.

If you flash a 4.4 firmware , you will no longer be able to downgrade to 4.3

:)
[Galaxy S 4 General] cannondalee:
Glad to hear that :D

The latest was the international one (AP_I9505XXUFNAD_481100_REV06_user_low_ship_MULTI_CERT.tar)

tried already:

I9505XXUFND7_I9505VFGFND2_I9505XXUFND7_HOME.tar - UK

I9505XXUFNB8_I9505OXAFNB8_I9505XXUFNB8_HOME.tar - German

AP_I9505XXUFNA5_373648_REV06_user_low_ship_MULTI_CERT.tar - Leaked

tried FNB8 wifi fix and FNB9 wifi fix. Nothing works, ;(
[Galaxy S 4 General] malybru:
Hi,

Although I am puzzled as to why your wifi keeps breaking , I did find this post:

http://xdaforums.com/showpost.php?p=51359162&postcount=11258

It must be worth a try.

You are now on a 4.4.2 firmware.

Flash the same modem as your firmware.

Look HERE

:)
[Galaxy S 4 General] cannondalee:
Thanks for all the help.

Just flashed wifi fix for current rom ( international one), so they match.

Same result ;((

Does it mean there is a specific rom and modem (matched) that work with my phone and i should just keep trying diferent ones?
[Galaxy S 4 General] malybru:
Hi,

What I was suggesting in my last post is to flash a modem on it's own.

But make sure it is a 4.4.2 modem.

The modem should match the firmware you are on .( I9505XXUFNAD )

Follow what he says in the thread I showed you,

:)
[Galaxy S 4 General] cannondalee:
Thansk all for your patience.

Solution:

Flashed together at the same time I9505XXUFND7_I9505VFGFND2_I9505XXUFND7_HOME.tar and its wifi fix.

Its ok now ;DDD
[Galaxy S 4 General] busbyeie:
Hi malybru thanks for getting back to me, would the flashing also apply with a custom rom if it was based on 4.4 not being able to go back to 4.3 ?

also if I flashed a custom rom say from the verizon side e.g hyperdrive would I need to change anything like the modem file for it to work on Virgin (UK).
[Galaxy S 4 General] malybru:
Hi,

Flashing custom ROMS means you need to do it through a custom recovery.

Most Custom ROMS do not flash the bootloader.

So , you could go up and down the firmwares.

The new bootloader would be flashed in a stock firmware through odin.

However , be careful to read the first post of the ROM carefully.

Some 4.4 ROMS do need you to change up to the new bootloader to work properly.

:)
[Galaxy S 4 General] busbyeie:
Cool thanks for clearing that up for me, next step for me is to install a custom rom and try not to brick my new toy lol. :highfive:

I have a Chanfire-rooted S4 with CM11. I never backed up stock recovery but I do think I have a backup of Toucwiz which I made just before flashing roms. It's a 4.2.x Toucwiz, before the Knox-crap.

If I want to make the phone completely stock can I just flash the touchwiz-backup and then through Odin flash a stock recovery if I find one to download?
[Galaxy S 4 General] samersh72:
I guess your nandroid backup of touchwiz is rooted.

if you want to go back to full stock flash the whole stock firmware.
[Galaxy S 4 General] richard-droid:
Yeah, I'm thinkin that the rooted backup will be unrooted if I do a Kies-update to 4.4.2. But how about the recovery? I have TWRP now, but if I sell it I should revert it to stock.
[Galaxy S 4 General] samersh72:
flash stock firmware with odin. stock recovery is included in the stock firmware and it will replace twrp automatically.

Guys if any one can shed light on my complications. Trying to return phone back to stock. I was on new bootloader with knox 0x1. Well tried flashing stock firmware that came with the phone got it off sammobile. But when using it with odin 3.04 and got failed bacuase of no pit file so got the pit file but its still not passing pit file stage. Just keep getting Operation failed and on the phone it shows the progress bar about lets call it 10% full but never moves. Progress bar never comes up on odin. Tried odin 3.04, 3.07, 3.09 and getting the same story on each.

Even wiped data and cache before flashing.

Any body got any idea.

Make sure the firmware you are flashing is equivalent or newer than the one already on your phone.

Also, wipe cache and data before and after flashing.

Thank you for this guide.

Tommorow I will connect the phone to another Pc and flash stock rom.

One question, is it safe to just use the Europe Stock Rom for my phone? Because I am not sure if my phone was branded, but I don't think so, and my carrier is not listed.

Oh, and another question, after unpacking the downloaded Rom, I got several files, I guess I need to flash this one: AP_I9505XXUFNAD_481100_REV06_user_low_ship_MULTI_CERT.tar.md5?

[Galaxy S 4 General] samersh72:
Ah....If you were on 4.2.2 (old bootloader) you can flash a 4.2.2 to avoid knox

Unroot s4 GT-19500

So here i was messing with my phone...So obviously a time came when i though about unrooting.However when i looked upon the threads i couldnt find a way to unroot without reflashing the stock firmware.

Anyways i tried unrooting with Kingo Root and VOILA it worked.

P.S.- I rooted my phone with kingo root

2nd time i rooted my phone By using Chainfire's Auto root package.

Unrooting worked well in both the cases :) :D

(In both the cases i had the stock firmware installed)

Unrooted means that you gained your warranty again?
[Galaxy S 4 General] 012512:
I was curious about this too. I heard also (it may depend on the service center) they don't know or doesn't care about software modding as long as the phone doesn't have physical damages, if you know what I mean.

[Galaxy S 4 General] samersh72:
I9505:

-for old bootloader, use triangle away to reset hidden binary counter then flash stock.

-for new bootloader, use triangle away to reset hidden binary country then flash stock, and if you have "knox warranty void 0x1" (in download mode), it can not be reseted to 0x0, so here it depends on service centers policy, they may accept warranty and they may not.
[Galaxy S 4 General] Hyena:
You have Knox or not, after one minute in the microwave oven and you're phone has warranty again ;)
[Galaxy S 4 General] abhinavparasher:
Well to all the people out there...There is NO WAY for the GT-i9500 to get its knox warranty back.

However, I had a camera problem with my s4,Turns out to be a hardware problem.I went to the service centre after unrooting and installing the stock recovery.They asked me if i had modded my firmware of kernel in any way.I simply told them idk wat it even means.Voila they repaired my phone and i didnt spend a cent.

So afterall...maybe it all depends on the service centres...
