Exclusive: I9505XXUEMI8 – Leaked Android 4.3 test firmware for Galaxy S4 (GT-I9505)

As you guys may know, Samsung takes some time to update its devices to the latest version of Android but always delivers the most stable and bug free build after a ton of R&D. It’s rumoured that Samsung will be releasing the Android 4.3 update for the Galaxy S4 sometime in October/November but we didn’t wanted you guys to wait that long, so we obtained a test firmware for all you Samsung fans out there.

Also, since HTC released Android 4.3 for the Developer Edition One, we just had to give some Android 4.3 love to the Galaxy S4 (GT-I9505) users. We would like to thank our insider because without our insider’s help we would not have been able to provide you folks with this firmware.
We have been testing this Android 4.3 test firmware since a few days now and can say that it’s really stable and the performance has received a significant boost, it’s much faster and lag free than Android 4.2.2. Samsung Knox and Samsung Wallet are present in this test firmware, Samsung Knox works like a charm but Samsung Wallet can’t be downloaded from Samsung servers at the moment. Also, there is a new Reading Mode which optimises the screen for reading, but only a few specific applications are able to use this feature, and there is a new improved keyboard as well. Most of the changes are under the hood, except a few minor UI changes here and there. Now the most interesting part, this firmware has improved colour reproduction of the display quite a bit and the text looks even sharper than before.

Keep in mind that Android 4.3 update is still under heavy development and Samsung may add more features before rolling out the official update itself.

I have recently installed the test 4.3 jelly bean firmwire posted in Sam-mobile in my s4 i9505. Now the official firmwire has released.
1. Did I get the official update via ota or kies?
2. If not the how do I get the official update?

When I installed the test firmwire all my data has lost. So now if I use the official update of 4.3 will my data be lost again??

Thank you

Hello, I have big problem. I can’t flash this ROM (or any other official). When ODIN flashing a “modem part”, flashing process fails everytime. I really don’t know what can I do now. I tried searching on Google, Xda-developers and here for last 5 hours and no solution. Can please anyone help me? Thank you very much.

Today I got my home back from the service center, they have replaced the battery which was the source to all the bootloops, and not the phone was not able to reboot.

I flashed this firmware and i’ve had a couple a problems

1)After flashing my device stopped booting at the pretty logo saying “Samsung” (a battery pull took care off that).

2)I whas unable to login to my Google account because i have 2layer authentication enabled and this firmware removed all my apps including the google authenticator app (i whas able to recover my account) .

3)Samsung Wallet says “cannot download now please try again later” every time i open that app what’s up with that ?.

4)Is it normal that a firmware removes all of your apps and why is there no warning about that !!!!!!!!! ?

Hello friends from all over,

My I9505 was network locked to a single carrier here in the Philippines (Globe). Wanted to switch to another carrier as they offer better LTE services. Did just that earlier today by paying a cellphone technician in the mall to network unlock my device.

When I got home, I researched the changed modem number on my phone, and found out that from the I9505DXUBMG5 Philippines version I originally had, I now have the I9505XXUAMDM Germany version.

It got pretty laggy but a Factory Reset took care of that. Other than that, I wanted to know if this change is okay? Will I have problems updating my firmware or whatnot considering I’m in one country, while my phone is “running” on another?


Kind regards,
A Noob in Learning

yes it will run ok but i believe the pda will not match in future samsung updates and will push “Your device has been modified. Software updates are not available” to your device everytime you check for updates.

So it’s either you revert your S4 to the original country firmware to get the official updates from KIES and Device “Update” Section.


download the firmware here in SamMobile everytime they release updates if you want to retain the unlocked status of your phone.

this is based on my experience when i accidentally installed different country firmware on my i9500.

Galaxy Gear works better with this ROM. Incoming calls now goes to phone as default. Weather works. And apps can be installed from gearmanager. Messages, email etc.. still doesnt work.

3 years 6 months ago

While I don’t recommend installing such firmware onto your Galaxy S4 or Galaxy Note 2, they are available. Those who wish to flash either build should do so with caution and back up their handsets beforehand.
If you want to recover the data in your Android phone, just go to http://android-recovery.net/.

If you want warranty It is a good ideea to see triangle away . It will reset your binary counter back to 0 to get the warranty back .

Hi Guys,

Has somebody any tip for my problem. I’ve a Hungarian GT-9505 simlock free device with XEH firmware. I updated this OXA firmware to my device and then my product code of my device had changed GT2I9505ZWADTB from GT2I9505ZWAXEH. So my product code had changed. After update when my device had booted into recovery I saw that “Multi CSC applied – DBT” or something.

Will my device’s product code change to XEH when I’ll flash the XEH Official 4.3 firmware? Of course when it will be out.

Hi to all . I mentioned in an earlier post my experience with 4.3 . Today i downgraded to 4.2.2 (udmh6) using odin 3.07 and It worked perfect , even the knox counter is still 0×0 . I just followed the instructions , flashed and the reset from recovery menu . I think That a new version of odin is required to make this downgrade possible .

3 years 6 months ago

Can you please elaborate a bit. I have been trying to downgrade by oddins and kies but no success.

3 years 6 months ago

Sure ! I downloaded the last firmware for my country , i did a factory reset while the phone was still 4.3 , downloaded odin 3.07 , put the phone in Download mode , installed the new firmware , did another Factory reset and evrything worked perfect . Maybe you should try to uninstall kies and Download the drivers from the internet , because kies might get in the way of odin and make It Crash .

3 years 6 months ago

Now i got another problem, while a downgrade is succesfull, my sg4 randomly restart upon open apps, and at every restart it will end in a boot loop, the only thing that makes it boot normally is connect a charget to it and it will boot without any problem. The battery is never below 50% but why kind of error is this? I can’t google the answere

3 years 6 months ago

I have this problem too. Very anoying

3 years 6 months ago

Guys. Power off ur device. Enter recovery by holding power+home+volume up buttons. Wipe data/factory settings wipe cache and the reboot ur phone

3 years 6 months ago

Gogolak I’ve done all what you mentioned above, I’ve also restore the firmware in Kies twice, I’ve tried restore firmware >empty cache>reset phone, that doesn’t help the restart and bootloop. So I tried reset empty everything and then restore. That doesn’t work either, today I’ve send it to service, because it keep reboot on almost every app, and the reboot ends in a bootloop, only by connecting to a charger then it will start normally

3 years 6 months ago

Its not that easy. I have tried that lot of times but its not working

3 years 6 months ago

To downgrade using KIES you have to do following.

and follow instructions, that KIES is showing. You will find all the necessary information to enter, they are located in a Label under the battery ( you’ll have to remove the battery.)

2. Turn the phone off
3. Put in it download mode ( Volume down+home+power key > press volume up)

That’s the procedure, I hope it’s explained so it’s understandable.

My galaxy s4, is running android 4.3 really smooth, however it has random crashes and ends in bootloot, I know for sure that some apps will crash the device and force it into a bootloop.
But there’s one weird thing, that is i can get it out of the bootloop by putting it into a charge and boot, that when the battery is 90% full.
I’ve tried to downgrade it but it has not been succesfull so far, I can turn the device on but the WIFI can’t be use, it won’t turn on, any advice ? I’m using the Nordic version rom.
If any1 know where to download bootloader/rom/Kernel/css for nordic galaxy s4, please post a link.

Turn off ur phone. Enter recovery mode by holding home+power+volume up buttons. Wipe data/factory settings wipe cache and then reboot. If wifi still not working try to reflash the 4.3 rom

3 years 6 months ago

I’ve found a solution to downgrade, instead of downloading stock rom around the web, I used KIES to downgrade and it worked liked a charm, everything is running like b4 i installed 4.3, but unfortunally flashing 4.3 rom does give me KNOX 0×1.

3 years 6 months ago

What procedure, please? Where can I find this option in KIES?

3 years 6 months ago

i have install the 4.3 firmware yesterday, everything works perfect. BUT there is no difference from 4.2.2 . so people keep 4.2 it is excatly the same . it is not faster, it doesnt have better colours bullshits.

Right, nothing fantastic on the 4.3 and the WiFi connection is very unstable.

Sam Chan

Only setback is that you will not be able to root the phone after installing this leaked version of 4.3 as the security software blocks SuperSU from running. Therefore, you will not be able to use all rooted software.

3 years 6 months ago

I was able to root after the 4.3 upgrade but it does tick the Knox warranty counter to 0×1.

Sam Chan
3 years 6 months ago

I also find a way to root but not all rooted software works. Anyway, i have fall back to 4.2.2 using Wanamlite ROM.
