Hello
I do have a Galaxy S4 LTE I9505 on H3G, now my phone is on the CM 5.1.1 lollipop and I want to turn it back to the official rom, I find two ROM's one to the baseband I9505XXUHOD7 and the other to I9505XXUGNJ3 which is my current one.
Now i want install the official ROM with the baseband I9505XXUHOD7 because its on the 5.0.1 and the other original is on the 4.4.2. So my question is if I can install the ROM with the baseband I9505XXUHOD7.
And this is a link for the ROM : http://www.sammobile.com/firmwares/download/48264/I9505XXUHOD7_I9505H3GHOD1_H3G/

Yes, but you will have to reflash the lollipop firmware one second time if the flashing method don't update the bootloader.
[HELP] NO sound & NO WIFI - S4 I9505 after flashing Stock 4.2.2 (downgrade Stock 5.0)
ISSUE: I have NO sound and NO WIFI after:
1) Upgraded to Stock 5.0.1. - did not like it THEN I;
2) Downgraded back to Stock 4.2.2
- AP: I9505XXUAMDE
- CP: I9505DVUAMD8
- CSC: I9505XSAAMD8
------------------
Odin Mode
product name: GT-i9505
Current Binary: Custom
System Status: Custom
Knox Kernel Lock: 0x0
Knox Warranty Void: 0x1
CSB-Config-LSB: 0x30

------------------
Don't why the above says Custom Binary when I flashed a stock ROM from sammobile
Please Help !!!
Downgrading from stock 5.01 to stock 4.2.2 could have tripped knox and set the screen to say custom.
So the bootloader and modem are now on 4.2.2?

For the gt-i9505, I see no KK ROM, only 5.01 ROM: http://www.sammobile.com/firmwares/database/GT-I9505/
Where did you get the 4.2.2 ROM?
What do you see under settings, phone for baseband?

From Phone: Baseband version: I9505DVUAMD8
KK = Kit Kat which is 4.4.2. My mistake because 4.2.2 is Jelly Bean.
I searched sammobile.com for the s4 gt-i9505 and only found firmware for the link in my post above. Following your link, I found the firmware.
As far as I know, Knox did not exist until the 4.3 firmware which leads me to believe that the bootloader on the phone is either 4.3, 4.4, or 5.01 while the modem is older than 4.3. This may be causing the problem. As a test. flash back to stock 5.01 to see if sound and wifi work.

I flashed back to 5.0.1 and Sound & WiFi now works again - what does that mean ?
How do I then Flash back to a Stock 4.2.2 ROM and have Sound & WiFi work after that ?
If it works on 5.01, then at least you know everything is working properly and the problem is the 4.2.2 rom.
i don't believe you can downgrade the bootloader to stock 4.2.2 which means you cannot run a stock 4.2.2 rom on the phone because the phone will have a bootloader that is not compatible with 4.2.2.

WT ??? Does that mean if you upgrade to Stock 5.0.1 you can NEVER downgrade back to Stock 4.2.2 ??
Yes, it certainly looks that way. On my i337m, I can flash back to stock 4.4.2 but nothing older.

Google you s^#(k !! how dodgy is that not allowing people to downgrade if there upgrades are crap!!
Is there another way ??
Can I downgrade back to 4.2.2 with another Bootloader or custom ROM ??
Would surprised if I am the only one in the world that wanted to downgrade and there was no known workaround ...
It has nothing to do with Google as it is Samsung that locks the bootloader.
If a phone could fully downgrade to a stock 4.2.2 rom, including the bootloader, I would not expect to see any references to Knox in download mode.
You could search but I have not seen any posts where an end user was able to downgrade the bootloader to a non-Knox version.

When you downgraded from 5.0.1 to 4.4.2 did you get any Know Issues OR Loss of Sound OR Loss of WiFi ?
Does the downgrade need to be a stock ROM ?
Knox was tripped from 0x0 to 0x1 but everything worked, probably because the everything went to 4.4.2, including the bootloader.
The downgrade does not have to be a stock ROM. Running a 4.3 or 4.4.2 custom ROM such as CM does not alter the bootloader or modem.

Does that mean I can downgrade from Stock 5.0.1 all the way down to Stock 4.3 with no issues except Knox tripped to 0x1 ?
Or does it have to be a customer ROM to have no issues ?
I have never used custom ROM's only Stock ROM's
Some bootloaders can be downgraded to 4.1.1 like I did with my note 2 but the s3 can't be downgraded at all. I think the s4 is limited to 4.4.2 .
Downgrade i9505 to 4.4.2
I downgraded my galaxy s4 i9505 from 5.0.1 to 4.4.2 and knox flag was not tripped.I think it will be tripped only if you flash bootloader without knox.Maybe if you don't care of knox flag and want to run android 4.2.2 you must flash kitkat modem to have working wifi..
Hello mr. Marduj5
I'm also a Galaxy S4 user and want to install stock 4.2.2. I did everything you said... but the only problem now is the microphone and the speakers don't work after flashing Kitkat modem. I had the Connections but the media is now the problem. Thanks for the help...
Hello, I tell them my story.
I have a i337m S4 ( has the same specifications an i9505 ) .
The fact is that if I flash one custom ROM or Lolipop original firmware , the WIFI does not work me , but if I install a AOSP ROM -CM 5.0 or 6.0 wifi works me perfectly.
Like, if I install the firmware KK me the wifi works perfect.
Equal treatment to flash the modem , but I find for my baseband as it is: I337MVLUGOC4
For example , finished installing the Albe95 ROM or Imperium ROM , the wifi is activated and the Second turns off and goes well ...
The point is that if I stick a Custom ROM Lolipop or Firmware Lolipop from TouchWiz , the WIFI does not work me :crying:
sorry for the English , I use translator
Which country is your phone made for? I see that OC4 may not be the latest ROM for the phone: http://www.sammobile.com/firmwares/database/SGH-I337M/
