Best route to downgrade to kitkat - Galaxy S 5 Q&A, Help & Troubleshooting

I have a uk unbranded 900f. I got it a month ago agony almost straight away it upgraded from kitkat to lollipop. I find it can lag when pressing the home screen, the recent app button and starting he camera. Also firefox is buggy and can lag and he text will blur at times. Previously I had a htc one x running viper rom. I don't find the S5 on lollipop to be any faster than my one x running jellybean viperx.
I heard that the s5 on kitkat has less problems so want to down grade to find out. I want to try kitkat stock first so want to know he easiest way to do this? Ie factory reset, odin flash etc. Also I need to know if there are any problems to look out for or special prep I should do. I am rooted, have twrp installed and have the reactivation unchecked. Alao whicj version of kitkat would bw the best to go to? Any advice is appreciated Thanks.

Factory resetting after upgrading to Lollipop solves a lot of issues, Id try that first
Latest KK G900F Stock ROM here and ODIN to flash it
Extract ROM
Load it into AP or PDA in ODIN
Stick phone into download Mode (Volume down & Home & Power)
Connect to USB PC
Hit start once ODIN says it's happy

Thanks Detection. I'll try the reset first then and go from there.

[Q] GS4 - How to return completely stock for warranty exchange

Hi,
I've been do many flash last 24 hours on my Galaxy S4(Model SGH-I337M, Telus). Initialy, i've the factory stock rom, rooted. So, yesterday, i've decided to install Cyanogen mods nightly on my phone. Not the first time i've been used it on my phone. No problem before. So, this night, after a friend show me the release canditate release seem to be more stable, i've been try to put it on my phone. So, accidentaly wipe all the data on my phone. When i'm back home, i've put again the samsung original rom from my operator(4.2.2), found here, on the website, whit odin. All completed succefully, but i've noticed that the wifi won't turn on after the flash, and no sound from the speaker. So, i've put Cyanogen nigthlies again to test if it rom relative, but same issues here, no sound, but the wifi was working. The phone was very instable, so. Then, finaly, put the original rom again, without any rooting. Stuck on samsung logo, that i've finaly got fixed by clear the data and cache. But, no sound, and no wifi. Instable too.
Precision about phone: Unlocked whit the service mode(work), and enabled AWS whit a software and file(tutorial found here)
My question is: Anything else i can do to make my phone work fine again, and does it's possible to make the phone totaly stock? When i boot up, i've noticed that the phone, whit all rom i've try, said on samsung logo: Kernel is not sendroid enfonced, warranty status: kernel, so i can't go to return my phone on warranty whit that. How i can erase that line, and make my phone seem to be no modified?
Just to specify, it's not the first time i flash a phone. Do many flash, whit galaxy s2, s3 and s4, and sure, mine. Got try Cyanogen, stock, know how Odin work and all, try many rom, and before today, never has any problem to do turn back, but now, it's seem to be impossible.
Thank you very much for your help, very appreciated!
I would flash the stock firmware with odin again. After flashing do a factory reset in the stock recovery.

I've just try this. Flash the stock rom whit odin, and factory reset on original recovery after. Same, no wifi, no any sound.
Just see yesterday, when i'm flashing, i'm flashing on the bootloader in odin(whit the tar for the stock rom). Today, correct this by flash on the pda section, still not work. Found here on the forum the stock bootloader, rom, csc, and modem, but when i do this whit odin, odin said fail.
Thank very much, i think my phone is dead, and nothing to do to exchange it on warranty.
I think Kies has an emergency firmware recovery mode.... maybe that'll work.

Just try this. Kies is the worst software i've ever see. The software completely freeze random. When i go to the emergency menu, never, kies recognize my phone here. I've tried to plug my phone, no recognized. Tried without plug it, no recognized. When i plug it, kies said connection in progress, and can stay here 30 min.
I'm a idea of what is my problem. Before do install of cyanogen, i've been applied the samsung official 4.3 update, whit knox. And, according to what i read on many forum, knox is not ereasable, So, it's completely freeze my phone, and nothing to do.
Anyone have the factory telus bootloader and other factory stock items because i want to put it stock.
Thank.
Finally get problems fixed by take the TELUS stock 4.3 ROM and flash it whit Odin. After, can flash cyanogen nightlies again and the phone work well again.
Whit the stock ROM, didn't see any line on the Samsung boot logo that i've rooted. After root this appear again. Knox regardless of ROM installed said 0x1.
If anyone have a fix to put it again 0x0 very appreciated otherwise the phone work fine and thank you very much for your help.

@Spacemonkie4207 never my itune was freeze, and i can do basic operation like transfer music or create playlist without any problem. My kies stay on connection in progress, and turn, turn, turn, but never connect. And when it connect, only one operation, and kies completely freeze, stop responding, need to close it, and open it again. Tried many cable, usb cable, reinstalling software, two other computer, but nothing to do.
I recovered back to stock from custom to 4.3 however if you do so, depending on carrier you could lose root and the ability to install custom recovery.
I would revert back to 4.2.2 (as it's knox free) go to samsungupdates (google it) and pull the 4.2.2 for your region and carrier. flash with odin 3.9
you'll lose root, but you can always perform again as long as not on 4.3 (with 4.3 u can still root if you remove all the knox stuff, u just lose warranty).

Screen lag

HI guys
so i just bought an s5 and i have massive screen lag, the phone is basically unusable, ive been told that it started lagging like this when the lollipop update was made, any ideas? cache wipe and factory reset do not fix a thing
cheers
Flash back to KK?
You think this would work? Seems strange screen lag? It's only what the guy said I bought it from could it be hardware?
Only one way to find out - quite a few people have lag issues with LP though
First choice......roll back to 4.4.2.......
Second choice.......Wait it out til you get OTA'd to the next upgrade......but even then, there are no guarantees that the lag will be fixed.......
I'm still on 4.4.2 and have NO INTENTION of upgrading to 5.0.+.......I've seen WAY too many people on XDA saying that LP has "screwed their phones over" in one way or another.........
Sent from my rooted kn0x0 stocKK SM-G900F S5
It's strange, the majority of people have problems with LP, I'm having none at all, immediately after the update I had bad battery life, read that a factory reset should sort it, reset the phone and have had no problems since
Everything works, everything is smooth, animations work great, no crashing, and battery life is fine
It is strange the phone is so slow it is impossible to use day to day, I'm just trying to work outhe if it's hardware or to do with the update, I haven't personally seen what the phone was like before you see
Well you're never gonna know unless you flash back to KK
Yes I will once I'm home, any recommended sources? Is kk still availible on sammobile?
Yea sammobile for the ROM, ODIN to flash
Do I need a certain rom? I'm on BTU - don't really understand it all
sollution
Go to sammobile. Find the latest vesion for ur device.
baseband:
Snapdragon bob7
exynos bob8
Then backup all ur files to a pc.
go to recovery and wipe
data reset
cache
dalvik cache
Then in advanced reboot into download mode
connect to pc
Using odin 3.07 or above select pda and select the rom file
then start. All ur lag should be fixed.

Is your phone a G900F?
If yes, you can use this ROM
https://mega.co.nz/#!89JSAA6B!cxvVzJ6fehliaGgPteMi9WQp1eJcNKVgHha22Dml7Ls
And ODIN here
http://forum.xda-developers.com/showthread.php?t=2711451
Load the .TAR of the ROM into PDA or AP in ODIN, make sure only F-Reset Time and Auto Reboot is checked
Make sure Re-Partition is NOT checked
Put the phone into download mode and hit start
It is the g900f , is the rom standard then? Doesn't matter where the phone is from etc?
It's the UK (BTU) version for the G900F, the exact ROM Samsung would have pushed out to your phone, the same one Im running on my G900F BTU
just before i do it,
SM-G900F
knox warrenty void 0x1
BTU
G900FXXU1BOB7
CSC version shows blank though in the app 'phone info' but there in *#1234#?
and csc version G900FOXA1BOB7 - is this why im having trouble because of the conflicting files?
Bootloader, Baseband and PDA versions all say the same thing on mine (G900FXXU1BOB7)
CSC version shows G900FOXA1BOB7
--
I'd just go ahead and flash it
here goes!
no joy :/ any other ideas? i thought that was a kk rom? seems like the same?
No, that was the latest Lollipop ROM - if you want Kitkat, grab one from sammobile dot com
Search in the firmware section for G900F then BTU for UK
Did you factory reset after flashing this Lollipop ROM?

Back button not working after software update?

Hi everyone. I just flashed back to stock (Koodo official firmware) to sell my Note 3 and now my back hardware button isn't working. I have searched the web and to no avail. Could someone please give me an idea of what I can do to fix this? Thank you!!
Which note 3 is it?
SM n900W8
I have the same model. I haven't used it for a while. I powered it on a few days ago to take the update from doc4 to doh1. I just tried the back and menu buttons using the doh1 ROM and they seem to work fine.
A friend of mine has the same phone and he flashed the doh1 ROM from sammobile.com over a rooted doc4 RIM and he also has no problems.
Both of us were using custom ROMs with a 4.4.2 bootloader and we both flashed back to stock using sammobile.com's doc4 ROM before moving to doh1.
I ended up flashing a stock n9005 zip TW rom and it is fixed - but I had to install TWRP again etc. Thanks for the help though!
Glad you got it fixed but I'm not sure I was much help.
Partially solved..
Hi.
I have done everything trying to solve this and can confirm the next:
1st: If you go back to Kit Kat, the capacitive buttons start to work again. Then you are offered a couple of OTAs (one after the other to get you to DOH1). After the first OTA, the buttons stop working again.
So first solution: stay on Kit Kat (probably not what we want).
2nd: Flashing a custom Cyanogenmod based firmware works, I used latest temasek's build, I am testing it to see if I can keep it.
3rd: I tried erasing almost every single partition (system/cache/dalvik(art?) cache) and flashing from scratch DOH1... wont work.
According to what I have read all around there is a system file that controls the capacitive buttons, probably that file is getting weird with the upgrade, I still need to install a official rom, root it and try to edit such file.
It's strange that some phones have no problem while others do. My friend and I have no problems but we weren't running custom ROMs before the doc4 or doh1 updates.

I wasn't running anything custom. I was on Official ROM (no root no anything, just Stock Samsung Software) as always with my Note 3. It was just that the DOH1 update make the damages.
Now I think I gotta stick to Cyanogenmod given this problem, unless Samsung says something and fix the thing.
Does this happen with TW-based custom ROMs too?
Dont know. As of now, I am trying to flash DOH1 again on top of KitKat 4.4.2

They say clearing the Cache of the Samsung Keyboard fixes the thing. Wont be able to test by myself til tomorrow
Edited
I have N900W8 bell version, using it on Virgin network.
worked flawlessly with KitKat (either with Bell or Virgin version).
I've only experimented with Note-based custom roms (KitKat only), since I need the pen functionality.
First attempt:
I have experienced the same, not properly working menu button and not working back button.
I was on rooted stock KitKat 4.4.2 (N900W8VLUCNB7 Firmware Virgin mobile version), rooted with Chainfire CF-auto root (Build ID:KOT49H.N900W8VLUCNB7) using Odin. (all the buttons working properly)
Upgraded to Lollipop 5.0 (N900W8VLU2DOH1) with Odin, rooted same way with CF-auto root (Build ID:LRX21V.N900W8UBU2DOL1). (Buttons do not work)
Second Attempt (No rooting involved what-so-ever):
Reverted back to stock KitKat 4.4.2 (N900W8VLUCNB7 Firmware Virgin mobile version, clean flash), all the buttons working properly.
Did OTA update through Wifi to, assuming, N900W8VLU2DOC4. (Buttons do not work)
Another OTA update through Wifi to N900W8VLU2DOH1(confirmed). (Buttons do not work)
For both of above attempts, buttons are working properly with KitKat, whether it was rooted or not, and not with Lollipop, whether it was rooted or not. I'm thinking it's just the lollipop issue.
Third attempt (using N900W8VLUCNB7 Firmware Bell version):
Reverted back to stock KitKat 4.4.2 (N900W8VLUCNB7 Firmware Bell version, clean flash), all the buttons working properly.
Did OTA update through Wifi to N900W8VLU2DOC4. (Buttons do not work)
Another OTA update through Wifi to N900W8VLU2DOH1(confirmed). (Buttons do not work)

Do you have the link for the stock Tom zip?
Sent from my SM-N900W8 using XDA Free mobile app
Ok. Pretty much tried everything while staying on stock firmware.
However, everything else seems to work okay other than the touch button.
So now im gonna root the stock lollipop and use xposed and gravitybox to manually remap the 2 touch keys. Will update
Hell yeah(excuse my language, but I'm so happy), I got this working!
Before I start listing my steps, please thank wrench588 here for me to find a confirmed working solution, and
thank stew721 here for the original post!!
No root on a stock lollipop (N900W8VLU2DOH1) Virgin firmware on Bell phone
1. Clean flash with N900W8VLU2DOH1 Virgin firmware on odin. (I'm guessing you actually wouldn't even need to do this step, if you are already on lollipop (N900W8VLU2DOH1 or N900W8OYADOC4 firmware)4N900W8
- I got my stock firmware from here
2. Download idlekernel here
- For Odin flash: download idleKernel-hlte-can-6.6.5.tar.md5 (for Canadian galaxy note 3 SM-N900W8)
- For recovery flash (ie. twrp): download idleKernel-hlte-can-6.6.5.zip (for Canadian galaxy note 3 SM-N900W8)
3A. For Odin,
a. open Odin
b. load into download mode (by holding Power+Volume Down+Home key together when turning on the device)
c. Load the idleKernel-hlte-can-6.6.5.tar.md5 into the "AP" on Odin
d. "Start" on Odin
3B. For Recovery(TWRP or CWM),
a. Boot normally and copy idleKernel-hlte-can-6.6.5.zip into your phone
b. flash idleKernel-hlte-can-6.6.5.zip file in recovery
Done.
Thank you so much again, wrench588 and stew721. I could not be happier
Next step for me would be getting my stock rom to get deodexed so I can install "xposed". I need to replace the function of holding "menu" touch button to pop up google search instead of S finder.

Hey , has anyone firgured out how to get rid of the "unfortunately Knox has stopped working" ? I had the same issue with the softkeys not working. This fix works but I get this message. I was also told to try flashing a PIT file with stock firmware to fix the softkey issue, but this did not work.
Maybe flashing supersu from TWRP will allow supersu to disable knox?
not to bring back a dead thread, but this is exactly what I needed. I needed to root to fix screen mirroring so I just used root uninstaller to delete knox.

S4 ODIN Failure com.android.phone crashes

So when this phone was on stock fng2 firmware long ago when it was current firmware. I sent it off to a guy who was offering very cheap unlock. used it fine since then. but wanted to put stock rom on it and make it completely Samsung official with no problems. so it is ready for selling. but when I get the latest firmware which is ok3 and flash with odin. after booting in those crashes start happening about 2 times per second. phone is useless. I made it to settings menu and looked at baseband and software version both show unknown so I flash stock ok3 modem still samething. then I try these full firmware images:I flash od2, same thing oh1, same thing, factory reset doesn't do a thing on the rom with issues. then I try fng2 it works perfect. then I use use od2 oh1 ok3 update.zip to get ti to latest version and it works perfect. modems upgrade and work fine. but when on latest version I reset phone from the settings menu to factory default same issue after phone as booted. so currently phone is useless if it is ever resetted. so no selling. any solutions.
the issue seems to reside with the modem. probably guy messed up a lot of settings in service mode?
You name it I have tried it most likely
any ideas anyone?
anyway to reset nvram to factory default.
i have reseted it in service mode. were it says a golden backup exists. that didnt solve anything
I've tried many many things but nothing seems to work for that issue. Only way I've gotten around it is by doing a dirty flash of kitkat with odin.

Galaxy s5 reboots just after galaxy s5 logo is shown, cant get into recovery mode.

Hi,
To make everything clear i will start from the very begining. I bought my Galaxy S5 2 years ago. It was on android KitKat back then. Everything was stable and it was working like a charm. When android 5.0 Lollipop was available in OTA i let it update. Still everything was ok. And now, about 1 month ago when android 6.0 Marshmallow came out in OTA for my device i also didnt hesitate. Now i regret it as hell. On 6.0 my phone went from stable as a rock to restarting every 5 minutes. I thought maybe its battery fault so i changed it but unfortunately it didnt change much. I blamed 6.0 for all this thing so i decided to downgrade it to 5.0 Lollipop. I did it thanks to youtube tutorial by android doctor - Samsung Galaxy S5 Downgrade Android 6.0 G900F Marshmallow To 5.0 Lollipop ( i was using ODIN and i flashed XEO rom for my SM-G900F from sammobile website).
For like 3 weeks everything went back to normal but one day i couldnt turn WiFi on my phone (when i pressed the WiFi symbol nothing was changing, when in settings i tried to slide it to ON position it went back to OFF. I thought ok lets reboot the phone then. I did it but from that moment my phone is as useless as a brick. It turns on, shows Samsung Galaxy s5 logo and immediately restarts. I cant even enter recovery mode. I can enter download mode so i tied to flash another rom (6.0) but it didnt work. Phone was still restarting in the same moment. I even tried to install TWRP but cant enter it also.
I had my own small company but it went bankrupt and i have huge debts which i will be paying for next 10 years so i really dont have any money to spend. I live without the phone right now. My life is a misery. Can you guys please help me to unbrick my phone? I will be very grateful and you propably cant imagine how much it will cheer me up to have it working again.
Sorry for such a long post and useless informations about my life but i had to let it all out.
I'd try going back to stock kitkat with odin (install the firmware from sammobile)
im not sure if you can go back to kitkat via odin once youve gone to lollipop, nor am i sure why anyone would. Just get the OK4 tar.md5 from either sammobile.com (very slow servers) or from here (much faster) and flash it in odin. should be god to go. then you can root, flash twrp and youre ready to ROM
