Restoring default Android version - Galaxy S 4 Q&A, Help & Troubleshooting

Hi
I recently bought a second hand S4 from Amazon but it seems that it have customised firmware installed; PhoeniX ROM. I was wondering what is the easiest way to remove this and bring back either the default or latest version of Android.
Thanks

Try to restore firmware throug kies application first, but surely, it will fail.
So the best option you have, IMO, is to download a stock ROM from sammobile, wioe the entire phone, and flash it

Ignore kies, it won't work
Just flash a stock ROM via Odin

[Q] T-Moible Galaxy Tab flashing

Hi
Ive recently been gifted a T-mob samsung galaxy tab. I had a few questions about the same, would be very glad if someone could answer them for me
1) Is it possible to flash it with Indian/Asian firmware? I did some reading aand found out that flashing with euro firmware is possible, so this sould also be possible? If so, can someone point me as to where i might get more info on this?
2) Once flashed, and connected via Kies, if a new firmware of that region is released, would it automatically update to the new version or it will have to be done manually again?
3) Is it possible to flash back to original t-mob firmware should i need to avail warranty in the future?
you help is appreciated.
1) Is it possible to flash it with Indian/Asian firmware? I did some reading aand found out that flashing with euro firmware is possible, so this sould also be possible? If so, can someone point me as to where i might get more info on this?
Flashing to Asian firmware is possible. I did it with Korean Firmware. However, it is useless in U.S. Market. If you are trying to flash it due to language, I would look for other solution rather than changing the whole rom.
2) Once flashed, and connected via Kies, if a new firmware of that region is released, would it automatically update to the new version or it will have to be done manually again?
Most likely it will need to be done manually.
3) Is it possible to flash back to original t-mob firmware should i need to avail warranty in the future?
Yes it is possible to flash back to T-mob firmware. Check Rotohammer's Roto backup process.

[REQ] Stock kernel file

Is it possible for someone to upload stock kernel file for 2.2.1 XXJPY (kernel version is 2.6.32.9 [email protected] #1). Version that is flashable via odin, not cwm version.
I am about to flash my kernel with custom one, but would like to have stock kernel near me, just in case that something goes wrong...
Subquestion is:
is it even possible to reflash to stock kernel via odin once you fot custom one (speedmode to be precise)? I think i read somewhere on forum that it is not entirely possible. Does someone have any expirience with this?
Samfirmware (http://www.samfirmware.com/WEBPROTECT-i9000.htm) has all stock firmwares.
Yes of course you can flash back to stock, you just need to make sure that lagfixes are disabled if you enabled one.
But honestly, I'm 100% sure you won't go back to stock after flashing a custom kernel or rom, it's just that much better.

Thank you very much.
But, as I can see, on this page there are whole roms to flash, I wanted only kernel files. Could kernel be downloaded somewhere?
I'm on stock rom 2.2.1 with CF-root kernel.
Haven't seen a stock only-kernel when I searched for it recently on this forum.
I decided now to download the full stock rom from samfirmware instead which I can go back to in case Kies won't allow me to update to Gingerbread. I figured there's no big difference whether I flash a ROM (which includes the kernel) or just the kernel, the effort is the same.
I just learned that returning to stock ROM (kernel) will be little more difficult for me because my phone is T-mobile branded!
If I flash to a stock firmware does that mean kies will then recognise my firmware as offcial so I can download new updates through it. Thanks

You can always use SpoofFW to flash to your original firmware

No as its not the firmware that came with the phone nor its Kies update .
As post above only method once you use Odin is either a backed up copy of original firmware and yes a few backed up or spoof fw .

Thanks for your help what do you mean by 'spoof' fw

Ok, this is my real problem. JJE might know solution to it...
Before i start flashing my kernel, ROM etc... I would like insurance that if in a couple of months something dies in my SGS, like speaker or something, I can go to repair shop and have guarantiee.
For that I would have to reverse all changes to virginly clean T-mobile branded ROM.
As I understand, to do that i would have to flash it via Odin with 3 files (PDA, PHONE and CSC).
Currently, when I type *#1234# in phone I get:
PDA - I9000BOJS5
PHONE - I9000XXJPY
CSC - I9000GCROJS4
so I presume that are the files version that must be flashed in Odin.
I managed to find all files except CSC code (for Croatian T-mobile 2.2.1 ROM). Couldn't find it anywhere.
Is it possible to put some Multi CSC and then later change it to right one ( I9000GCROJS4) with spooffw?
Or there is another way to find/backup/extract CSC from my current configuration.
Or another way to get back to stock branded ROM if anything goes wrong?
I can do nandroid backup because I cant get to CWM because i dont have 2e recovery (that is one of reasons I want to flash to another kernel, to get 3e and CWM).
Please help!

hey dude if i do a flashing faliure will kies fix it?
What FW is on your phone right now? and what are you trying to upgrade to?
Questions belong in Q&A, not General.
Thank you.
Now that this is in the correct place...
Stock ROMs do not come in a flashable zip format. Kies is not going to help you in this regard, and is absolutely useless for fixing flashing problems that may crop up. Thus, you'll have to use Odin, like it or not.
I'm assuming you want to upgrade your ROM, so please post the following information:
1. Model Number
2. Android Version, found by going to Settings > More > About device.
3. Firmware Version (AP, CP, CSC), found by dialing *#1234# in the dialer or by installing Phone Info from the Play Store and running it.
4. Service Provider
5. Country
6. Is the phone rooted? (Yes/No)
7. Is a custom ROM installed? (Yes/No, and the name of the ROM)
Some of this may seem redundant, but putting it all in one post makes it easier to help you.

Flash new firmware

Hey all!
So, I've got a Note 3 SM-N9005 but I've got this issue. When I try to update my Kitkat to Lollipop it says "Your device have been modified, Software updates are not available". I did have it rooted around a year ago and when I click 'Status' at the device info screen, it says 'modified', so I guess that's the issue.
Either way, I'd like Lollipop since I've heard it can solve the bad wifi connection issue, but I have no clue on how to install the new firmware safe and sound on my Note 3.
Does someone have any tips for me on where to find the newest stock firmware and how to flash it on my device? Or how to remove the 'Modified' status so I can get the update over the air?
Thanks in advance!
P.s. My Knox isn't void, it still says 0x0
Google ?

Yeah I read a lot already, but most of it is dated back at least a few months. And I thought, since this is an expert forum.
Should I just backup everything (like put everything on my computer and use some software to backup game data + sms data etc.) and use Kies? Or should I use Odin and download stock firmware from Sammobile? I'm really not an expert and I don't want to **** it up and brick my phone.
Have a look in the developer section, there are several different custom ROM you can use, I currently have the Phronesis ROM on my Note3 it's a Lollipop Note5 ROM and it is working very good with all the Note5 features such as screen note on lock screen etc.
hi, backup all to your pc and download stock rom and flash with odin or custom rom, but if you want ota flash stock
