Downgrading to KitKat 4.4.2 from Lollipop [Galaxy S4 I9500]

Hey there mate,

I must give you credits for your awesomely written thread and very much explained to even newbies like me.

However I wanted a live support from you personally if that's possible of course.

I've upgraded to Lollipop 5.0.1 through software update in my samsung parameters. Which means it's an official version. My phone is the same presented in your topic, a Galaxy S4 purchased under warranty, legal stuff if you know what I mean.

It came with android kitkat 4.4.2 I believe, and I was happy with it in every way. One day, I told myself (stupidly) why not upgrading and trying this lollipop thing. I did that and Boom, my phone started acting up, heating, when I try to push menu button for a long time to clear the running apps I get "System UI has stopped" anyways, a pure catastrophe !

Now that I did that, I want to come back to kitkat however, the version you provided its download link is not designated to my country which made me stop and think about it before I harm my phone (Which can be wrong of my part thinking like this, I'm a newbie sorry). The version was for Argentina, and I'm from Algeria.

Can you please tell me how can I chose the suitable one for me, or if it does not matter which one, can I chose a firmware designated for usa or uk or any other country that I like ?

I have another question please, regarding the full wipe to the device. How can I do that ?

At the end I ask you kindly to excuse me for the extra trouble if you wanted to help me, and thank you in advance.

Best regards,

Dessi

hi everyone i have purchased S4 black edition but it is on lollipop how can i downgrade it to kitkat (indian) also bootloader is updated to lollipop any help is appreciated :fingers-crossed:
[Galaxy S 4 General] Tanamly:
Goto page 12 I think of this thread, you need to flash the modem file for Lollipop

Worked for me and for everyone else ;)
[Galaxy S 4 General] Tanamly:
HYG mate.. This is from a SAUDI Lollipop... hope it works for you
[Galaxy S 4 General] chandramani123:
I'm from India flashing Argentina firmware file would work for me or not ?
[Galaxy S 4 General] Don Kingkong:
it could work

but i think it's more safe if you flash the firmware from your own country

On kitkat stock (and on every other stock based ROM) i see a weird lag on whatsapp, everything runs smooth except sliding through pages (from chats to contacts or contacts to chats or calls). It's so much laggy. Anyone else having this issue?

BTW, is it possible to downgrade the bootloader as well? I'm on rooted stock kitkat (downgraded from lollipop, thanks to you)

Please help!!!

Hi

i have followed the process above, my SIM was not detected., however my IMEI does show.

i have moved back to Lolipop using ODIN and it still says NO SIM CARD, the phone does show my IMEI.

i didnt take backup of my phone before i started this process, i bought this phone when i was in India, now i have moved

to Australia, can you please help me. i want my sim card to be detected.

Thank you
[Galaxy S 4 General] Mandark52:
Alright try this:

1- boot into recovery and wipe cache

2- wipe data after it.

If this doesnt work then remove the sim card and blow air into the sim socket. Sometimes its the dust responsible.

Report back if problem occurs.

All the best.
[Galaxy S 4 General] apexi07:
Thank you for replying

I have tried that, I have also took the phone apart checked the SD and SIM card connecter

It still doesn't seem to work, any other suggestions
[Galaxy S 4 General] Mandark52:
Have you checked inserting the sim in other phone and whether it is working there?
[Galaxy S 4 General] apexi07:
Thanks

Yes I have tried my sim in my other phone it worked fine, I have also tried other sims in the S4 but no luck

I will try replacing the SIM card reader

If you could help me with any other Suggestions do help

Thanks

Galaxy S4 GT-I9500 issues

Hi Guys,

I am having issues flashing my GALAXY S4 GT-I9500. Unfortunately i cant remember my carrier and so i have tried different roms. First i successfully upgraded to 5.0.1 lollipop which was successful and i started receiving some strange popups, application closed phone is overheating and so forth and then it won't open any app cos of that pop up message. Now i tried downgrading, after flashing with a kitkat rom, the pass message showed on the oiden and and the phone restarted but got stuck at the samsung logo and wont boot again. restarted the phone but still won't boot. Successive roms i have tried but still not working. Please i need help.
[Galaxy S 4 General] Mandark52:
Did you gave a hard reset? Flash the official lollipop firmware again and check whether it is booting up. Its a soft brick and probably a hard reset will do the work.

All the best.

Report back for any help.
[Galaxy S 4 General] Atrix2dBeast:
Thanks a ton Mandark52....I had followed ur guide ....and flashed 4.4.2 indian firmware..all is working fine except one thing..idk if its related here or not but somehow my phone is not going into deep sleep...gsam battery shows that its been held awake by doze...but I don't have it installed....if you can suggest anything on this it would be great help!

Thanks once again and kudos to your efforts!!!
[Galaxy S 4 General] Mandark52:
I would be happy to help you again, can you please elaborate your problem?

[Galaxy S 4 General] Fukel:
If i downgrade from my official lollipop to official kitkat and replace modem.bin will it trip knox?
[Galaxy S 4 General] Mandark52:
Probably no because whatever you are flashing is official or a part of official firmware. I already had rooted my device so it was tripped. Make sure you dont flash any custom recovery.

All the best!
[Galaxy S 4 General] Fukel:
thanks I did it and it didn't trip knox, also my IMEI wasnt null after i flashed kitkat so I didn't replace modem.bin. I'm using i9506 phone

I have I9500DDUHOA1 firmware and i want it to make it as before it was kitkat 4.4.2 then of which of the country's firmware do i download ?
[Galaxy S 4 General] Mandark52:
You need to download Indian Firmware INU/INS any one will work. You may try the MODEM.bin that I have attached in previous post.

Report for any problems.

Worked Great!!! I followed your steps and again I'm running android Kit Kat on my S4. I used Philz Touch 6.48.4 to do the wipes. Previous to Lollipop I was using ARO 4.4.2. Lollipop have a nice interface but it really devours my battery

Thank You very much!!!!

This 'tutorial' worked for you?
[Galaxy S 4 General] elias_gabriel:
I don't really know, cause I only tested doing a succesfully downgrade from SER 5.0.1 to ARO 4.4.2. You can try if you want and if you don't mind losing apps and data in the wipes.
[Galaxy S 4 General] rinkulsk:
Can u share 4.4 2 firmware on Google drive plz
[Galaxy S 4 General] S_7:
Yes but I ticked the update bootloader in Odin and it worked
[Galaxy S 4 General] elias_gabriel:
Great! So glad it worked [emoji4]

About changing to TML 4.4.2 i really don't recommend, because one of two, or you lose the baseband/imei or Odin will fail in the process. Better keep on this version, is sor far the best 4.4.2 firmware for me, i'm using right now! [emoji6]

if i rewipe everything following this tutorial and flashing the Argentina rom will this sim card issue fix?
[Galaxy S 4 General] rinkulsk:
Flash 4.4.2 modim and all will be fine
[Galaxy S 4 General] tdssmarty16:
you mean that in case any kind of modem related issue like no imei , null imei etc occur then they can be fixed by flashing the modem via odin even if we dont have the backup of original imei ?
[Galaxy S 4 General] rinkulsk:
Yup I did that only and all worked fined!

Thanx in advance.
[Galaxy S 4 General] elias_gabriel:
Let me see how can help you. You came from the indian or russian lollipop version? And do you remember which was the latest official kitkat 4.4.2 firmware that worked for you after installing lollipop?
[Galaxy S 4 General] elias_gabriel:
Why don't you tried I9500UUBGNJ1 firmware instead of I9500XXUFNI2? Try with the recommended firmware.

No, only i9500 variant.
[Galaxy S 4 General] rinkulsk:
Follow properly with all necessary files which are in description and u will be on kitkat am also on kitkat!! Thanks op

[Galaxy S 4 General] rinkulsk:
Sorry upload speed is dam slow
[Galaxy S 4 General] echohack:
I have the i9505, I've flashed back from 5.0.1 6 times now and sometimes it would fail in odin making it impossible to boot into anything but download mode. What fixed this was flashing only the pit file, then reboot and reflash rom.
[Galaxy S 4 General] elias_gabriel:
Thanks for the tip dude ;) Sure it will be usefull ;)
[Galaxy S 4 General] Rahman Alasadi:
indian lollipop ! .. and i was use ozcan room
[Galaxy S 4 General] elias_gabriel:
I meant, the latest 4.4.2 official firmware you used, not the rom. Anyway, have you tried the recommended 4.4.2 ARO firmware to make the downgrade, or you just used any other?
[Galaxy S 4 General] warisman:
can i use this from china leaked lollipop ?
[Galaxy S 4 General] elias_gabriel:
You can try and then post the results :)

But if you have flashed the 11gb pit file when installed the leaked version, the downgrade will fail. First of all you have to flash 8gb pit file through Odin: HERE THE FILE, then check that your internal storage is about 8gb. Finally do all the recommended process on this thread ;)
[Galaxy S 4 General] Rahman Alasadi:
no i used Russian V !! i cant download ARO V because of our slow internet .. is there any different ?:rolleyes:
[Galaxy S 4 General] elias_gabriel:
Sorry then, I can't mirror a huge file like that because my slow upload speed. If you try with another 4.4.2, the downgrade maybe fail (that's what happened to me, till I found this one).
[Galaxy S 4 General] warisman:
how can i use that adonis ?

just use that pit on download mode from my phone or when i install KK ?

and how i use the recovery file with img extension ?

sorry i'm newbie at this

Alternative guide for downgrading to 4.4.2 (any region and not specific region)

I firstly thank [MENTION=6158804]elias_gabriel[/MENTION] for sharing his solution with us.

Here is another way of downgrading your I9500 5.0.1 to 4.4.2 . The only difference is that in this method you can flash 4.4.2 firmware of ANY REGION without losing your IMEI number.

NOTE: This is for I9500 only and I haven't tested this on other variants. So I am not responsible for any of the damage to your phones and your curses :P

Requirements :

KK 4.4.2 firmware.(mine was: I9500XXUFNI2_I9500ODDFNI1_INU)

Lollipop 5.0.1 firmware.(mine was: I9500XXUHOAA_I9500ODDHOA2_INS)

Odin_v3.09.

7-zip.

Following these steps you'll successfully downgrade to 4.4.2

1) - Boot into RECOVERY (custom/stock) and wipe data reset.

2)- Now boot into DOWNLOAD mode (volume down + power + menu)

3)-Assuming that you have your usb drivers installed connect your phone to PC and open Odin_v3.09.

4)-Flash KitKat 4.4.2 firmware from AP.

5)-After Odin gives a PASS and your phone restarts and after completing the initialization you can see that your IMEI is nulled.

6)-Now use 7zip to open the 5.0.1 firmware .tar.md5 file and extract the MODEM.bin file from the same.

7-)Turn off your phone and boot into DOWNLOAD mode and connect your phone to PC, run Odin and flash this MODEM.bin from CP.

After successful flashing your phone will reboot and you will see that you have your IMEI number and your I9500 will be on your preferred network.

BUT the BASEBAND version will be of Lollipops firmware as we flashed its modem.

Tested and working on my I9500 with INS/INU firmware.

Thankyou and All the best!

Hit thanx if helped!

Also I would request [MENTION=6158804]elias_gabriel[/MENTION] to add this guide as an alternative solution to this post.

from where i can get modem.bin

Recently i downgrade my samsung galaxy s4 from lolipop to an kitkat an indian firmware I9500XXUFNI2_I9500ODDFNI1_INS but cant make call it is saying registered network but imei and baseband showing and ok also so from where i can download modem.bin
[Galaxy S 4 General] Mandark52:
Be adviced!!! You will require modem.bin from OFFICIAL 5.0.1 FIRMWARE only and not from the KitKat firmware!!. The modem.bin file is located in the 5.0.1 firmware. You just need to extract the modem.bin file from it.

Lets consider a firmware say I9500XXUHOAA_I9500ODDHOA2_INS.zip.

Extract it to get this --> I9500XXUHOAA_I9500ODDHOA2_I9500DDUHOA1_HOME.tar.md5 file.

Now RIGHT CLICK on this .tar.md5 file and from 7zip select Open Archive. (This will work only if you have 7zip installed in your pc)

After opening the file you will see different img and bin files.

Find the MODEM.bin and copy/extract it on desktop or anywhere.

Hope I am clear enough.

Any problem report back.

Hit thanx if helped!

All the best.

thanks can u give me link of 5.0.1 firmware

[Galaxy S 4 General] Mandark52:
Firmware - http://www.sammobile.com Just select the firmware section and type your phone's model number. Then you'll get a list of firmwares, so select according to your country/region (where you live :P).

[Galaxy S 4 General] Mandark52:
Well I don't have a good net speed as I use BSNL. So I cant upload the firmware sorry for that. You ll get around 60-70kbps speed on Sammobile which will take around 5 hours roughly to download the firmware. Still you can search here - http://xdaforums.com/showthread.php?t=2265477 .

Beadvised download the firmware considering your model number of S4.

can you upload modem file.

I have tried exact as you have mentioned but still my handset is showing no sim inserted. Can you upload the modem file so that I can flash it in my device :)
[Galaxy S 4 General] Mandark52:
Which 5.0.1 firmware do you have? I assume you have flashed the modem.bin as CP through Odin after flashing 4.4.2 firmware. Still I request you to give me the details of your both firmwares.
[Galaxy S 4 General] pankaj836:
I9500XXUHOAA_I9500ODDHOA2_I9500DDUHOA1_HOME.tar.md5 this is for lollipop and

I9500XXUFNI2_I9500ODDFNI1_I9500DDUFNI1_HOME.tar for 4.4.2. I have downloaded both the firmwares from SAMMOBILE. When I used the menthod suggested by you my IMEI is coming null in 4.4.2. Also when I upgraded to lollipop in that also IMEI is coming null. Please suggest how to get back IMEI.
[Galaxy S 4 General] Mandark52:
Did your phone detected your sim card when you were on 5.0.1?

After this you downgraded to 4.4.2 and as expected you got no IMEI and then you flashed 5.0.1 again and still no IMEI right?

If your phone detected your sim previously and now it is not detecting even after flashing official firmware then somethings might be wrong with your flashing!

Alright don't worry try this:

1.Flash official 5.0.1 firmware (delete the tar.md5 file as you have extracted its modem and extract the firmware again from the original .zip) through Odin.

2.Give a hard reset through recovery.

3.Flash 4.4.2 firmware through odin and give a hard reset.

4. Then flash the modem.bin file extracted from the 5.0.1 firmware.

Note : If you are using Odinv3.04 then flash modem.bin as PHONE and if Odinv3.09 then as CP. Repeat the procedure if it fails.

Alternatively you can root your I9500 when you are on 4.4.2 by installing a custom recovery and then install a custom rom. This will surely give you IMEI back.

I still suggest you to CAREFULLY follow the steps. I have attatched the modem in a zip file below extract it and flash. Hope it works.

Report back if any questions I ll be always there for your questions.

All the best!
