Samsung S5 - Lollipop - can i downgrade back to KitKat

Hi Guys,
I stupidly got excited and installed the official Lollipop (S5 on THREE UK network) update when i was notified.
BUT...
I want to go back to KitKat as i preferred it (i wont go into reasons why)
Is there a downgrade path for me, either officially or unofficially?> I dont think there is at the moment.
Thanks guys!
Yep, this forum is literally packed with instructions on how to do it, a simple search will bring up what you need
hi thanks, i thought with the new protected bootloader i didnt think it possible.
this is what i read:
Note: The G900FXXU1BNL9 Android 5.0 Lollipop update comes with a protected bootloader it is clearly emphasize that the “SE for Android Status – Enforcing” that might cause issues when you try to downgrade to the old software updates. This also applies if you are planning into rooting and installs any custom recovery and any unsigned firmware once you are on Android 5.0 Lollipop , so please be aware with that.

Yesterday I tried out AllianceROM 6.0 and a few hours ago I went back to 4.4.2 'cause I liked it better than Lollipop. Here's what I did :
1. Enter Download Mode and flash STOCK 4.4.2 KitKat firmware in Odin (I used 3.10.6) and let it start booting.
2. It won't boot, this is normal (I panicked when this happened though ).
3. Go to recovery and factory reset/wipe data your phone.
4. Now hit reboot in recovery and your phone will boot up again (YAY :sun.
5. OPTIONAL : If you've made a nandroid backup before going to 5.0 you can now flash TWRP and restore it over your STOCK 4.4.2 KitKat firmware.
Hope I helped Let me know if it works out for you!
SUCCESS!!!
All sorted.
The hardest part was finding a link to the rom. sammobile kept giving me a gateway 502 error.
im now back to kitkat, AND no THREE UK rubbish.

downgrade official lollipop to official kitkat 4.4?

Has anyone successfully downgrade official lollipop 5.0 to official kitkat 4.4? How? Is it safe to do it? Please help [emoji38]
I am quite sure a lot of people have gone back to KitKat from Lollipop, including me. In the course of last one week I have flashed Lollipop at least six times and came back to KK each time. So yes, downgrading is absolutely problem free.
Thank you devil

I would save all your personal data to the PC desktop. Wipe everything ( twice ), and then do a factory reset. Now odin flash back to whatever version of KK OS you want to run. Make sure you use a complete stock .tar firmware ( system/modem/bootloader ) from xda or sammoblie has them. Once you flash back to stock, odin flash it again to make sure everything installs. Then root and reinstall your data. If you do a lot of flashing from lollipop to KK, your going to have to take out the trash every once in while for lack of better words. I do a lot of flashing and end going back to bone stock about once a week, this helps from corrupting vital programs like efs. So in other words there is no magic pill. For more info click my signature the versions of KK might be different but the procedure is the same.

Sorry i already fix this. After flashing KK i flashed Lolipop modem manually then it connect to my network. Then i flashed back to KK modem which is GNG1 and its working like a charm.
Hi, I am using Samsung Galaxy Note 3 and recently updated to Lollipop(Not any ROM). Now I want to do factory reset and want to know that after factory reset process Will my phone land on Kitkat or Lollipop?
It would be greatly appreciated If someone can help me on this.
Thanks

Downgrading official lollipop (XEO) to Kitkat (BTU)
Hello Note 3 users. I would like to ask (maybe someone already tried) to downgrade official (not leaked one with bugs as was mentioned) lollipop to kitkat? My phone originally had BTU kitkat, but I wanted to test lollipop and downloaded one from sammobile (XEO). Flashed as it was described in Sammobile website, everything went well. Rom is working well, but gps takes ages to fix, and only a few satellites. They are always lost while driving. Because of this reason I would like to come back to BTU kitkat again (get gps working normally again and receive future OTA updates). Can I flash Kitkat like it's described in sammobile? Wouldn't I mess the bootloader or something? (XEO Lollipop to BTU Kitkat)
I successfully downgraded from Samsung's official 5.0 to 4.4.2. I wiped the phone first in recovery. Then flashed using Odin version 3.09.
My Note 3 is an SM-N9005.
After receiving the 5.0 update yesterday for my Note 3 (product code XSI) and not liking it very much I will be downgrading again. At least the newer build in the XSI ROM seems more stable than the BTU ROM I tried before but I will still downgrade. One of my favourite apps, Delayed Lock, isn't working on 5.0.

Still got no available update for I9500 (lollipop)

Hi everyone ! I have my s4 for like 4-5 months and i still didn't get the lollipop update, i'm frustrated because i have a lot of friends who have got it and mine says "The latest updates have already been installed" . I just flashed stock 4.4.2 firmware so the device is CLEAN. Any ideas ? Should i try to flash 5.0 directly ? Are there any risks?
Samsung rolls its updates out based on region, carrier and production date, it's normally a few months before everyone gets the update. The update's been ready for quite a long time, but even mine only got it last month. Sit tight!
As to flashing, well the risk is bricking your phone.
I know that, and the fact is all my friends are on the same carrier and they got the update months ago. I strongly thinks it's my phone the problem.
No one wishing to help ? I'm sure it's something wrong with my phone, but i can't say what, i am just a noob. Last time i flashed some 5.0 CM firmware, then when i flashed 4.4.2 stock, i had lost my IMEI or something like that, i had to search internet 4 days to 'repair' it. It may have something to do with it. PLEASE help me ! If you won't help i will flash it manually w/e.
You can flash via ODIN, there is no risk and its virtually impossible to brink the S4 if you read well and perform everything according to instructions.
My i9505 was originally from Austrailia - Vodafone, and AFAIK it still has 4.4.2. Thankfully, my phone wasn't carrier locked so i was able to safely flash 5.0.1 of another region and its working perfectly for a long time now.
Flash there's no risk

I had your same problem. All my friends got it in December but I Didn't get it. So I flashed the stock Russian Rom which was the 1st one to come out via Odin. So there was no issue only google now didn't work as it is banned in Russia. Finally after a few months samsung released it for my country and I flashed my country update over Odin and google now also returned. Flashing via Odin is the best way to receive the update for impatient ones like us (oh and don't worry once you flash your country Rom back you will also get OTA updates as normal) l

I don't really see a reason as to why someone would want to downgrade back to 5.1.1 as 6.0.1 is amazing. Thanks for the tutorial anyways.
Btw the google drive link doesn't work.

I dont own that device, but i thing this would work:
Flash latest 6.0 firmware with samsung smart swich (PC), enable oem unlock in settings, flash twrp for 6.0 with latest odin, do a factory reset and a full wipe (except external sd an android secure). Then download latest 5.1 firmware for your device an flash it with odin (it will take some time).

You are stuck on Marshmallow
Hai bro,,,
u try this one after flashing offical firmware simply reboot your device into recovery mode by pressing Power + Home + Volume UP and do a wipe data/factory reset, and wipe cache partitions then reboot your device, it will start properly and all problems are now solved,,,,,

With the J500H, Samsung decided to lock the bootloader, meaning you can't downgrade. J500h seems to be the only locked device. Unless someone finds a way to unlock the bootloader then you are stuck on 6.0.1.

u can show me. how to flash with odin (
Firmware downgrade Samsung J500H from MarshMallow with the second loader to LP.
Those who are faced with the inability to roll back to version 5.1.1 are uncomfortable with using their phone.
We need to either use the Philippine firmware or install a custom firmware Belousova.
I found an acceptable way to flash my phone with a stock firmware.
For rollback, we need a four-file stock firmware J500HXXU1APA5 or J500HXXS1APE1.
File BL with the second loader BL_J500HXXU1APA5_CL958143_QB8363487_REV00_user_low_ship_MULTI_CERT.tar or BL_J500HXXS1APE1_CL1011281_QB9453563_REV00_user_low_ship_MULTI_CERT.tar .
Odin.exe.
Please note: these files for the regions: CAC, CAU, SEK, SER, SKZ.
In other regions, wi-fi or a radio module may not work.
For other regions, you need another file for a specific firmware.
If you need another region, write me the name of your firmware.
The process of the firmware I will not describe, it is well known.

First update to MM have the some botloader like LP. But next update have other bootloader and you can't boot LP with odin to your telephon.
10:32 And some more - Philippines firmware LP 5.1.1 have second bootloader. You can downgrade from last update MM to LP 5.1.1 very easy.

I found how I can help for you.
You may download firmware from here :"goo.gl/Yk1Byz" and unzip and flash in odin this firmware.
Then if some hardware not working you may download firmware for your region from here:"goo.gl/SdcwhA"
and unzip repeat the flash with odin but with one file firmware.
And If you don't update your telephon to MM you can flash telephon using only this stock firmware. Save it. First file you can delete.
I am sorry - in first step you may set BL for APE1 file from my blog . It have second bootloader for firmware.
