Hello
I was on stock 4.4.2 kk, did a backup in philz then flash Bliss Pop [AOSP/CM12] BlissPop 1.9 Unofficial [2015/01/30] From what I read I need to get old bootloader if I want to go back to 4.4.2. Question wouldn't the bootloader be in my recovery backup so if I reinstall 4.4.2 it will be included?
If not can someone point me to instructions on the steps to go back,and where to find BL
Thanks
4.4.2

Hi
Download this from Play and check your BL see if it changed.

If you need to go back use Odin flashed the firmware file from your country, downloaded from SamMobiles which contains the 4.4.2 bootloader and the whole kk rom
i install bootloader SM-N910H_WanamLite.OH4_BL_Modem.tar.zip on Sweet ROM V14 BOE3 5.0.1H rom
now my note loop on bootloader , how can downgrade bootloader?
i search in google for bootloader 5.0.1 but i dont find any files .
sorry for my bad English

Did you take the OH4 update or flash that tar? I'm on Sprint OG5, and I know once you take the 5.1.1 update or tar you are stuck with the 5.1.1 bootloader and 5.1.1 roms. I odin'd a special tar that an xda member put together that had the 5.0.1 bootloader but updated everything else to 5.1.1 which lets me flash anything from 4.4.4-5.1.1. The 5.1.1 bootloader locks you in place.
So if you took the 5.1.1 OTA update or flashed a stock 5.1.1 tar through Odin than you can only flash 5.1.1 roms. There is no going back to 5.0.1 or 4.4.4.
Hello, Death-Dealer.
Could you please post that special .tar file you mentioned above? I'm in need to downgrade my phone too...
Thanks in advance.
Anybody got the stock firmware for 830LC with LTE version? Or do you know where to download?
Thank you.
Try to look at needrom.com. Also look here as some topics are related to 830LC and contain links or howto's, for example
http://forum.xda-developers.com/showthread.php?p=63308879
if what you need is the stock rom of the kitkat one it was already given to you
i have no knowledge of an available (YET) official lollipop stock rom for your model, but going up to Lollipop can always be done by taking the OTA after a KitKat stock rom flash, so this is not an issue if you are on KitKat
the problem is when your tab is already on Lollipop and you want to go back to stock KitKat (to stay there or to take the Lollipop OTA), if you just flash the KitKat rom you will softbrick on the first reboot after flashing kitkat because your tab would try to boot a kitkat system from a lollipop leftover initialisation system, this can be solved too with some minimal effort/knowledge but as you told already you don't know how to use a terminal so i would suggest that you keep waiting (or just play a little to learn a minimal knowledge of android flashing tools).
or wait some more so i somebody will pack an all-in-one flash stock KitKat rom package for your model with the bios downgrade (Lollipop to KitKat) included
i don't think Lenovo would ever release a KitKat stock rom flashable directly from Lollipop (this would go against their upgrade/one way policy)
Thnaks pal, you've save my day
warning
This method will not work anymore if you upgraded to QI5 new bootloader/baseband because it's locked to binery 5 it's impossible to downgrade and dev firmware will fail in odin.
This method will only works with older bootloaders only before QI5
I have successfully downgraded to kitkat after pull my hair for days and unlocked for any sim worldwide if you guys like kitkat like me and wanna unlock your sim network follow these institutions.
1,download developer kitkat firmware and flash via odin 3.10 this firmware is for developers without user apps and its empty but good thing is it will let us downgrade to kitkat bootloader no matter you are on 5.0,5.1 1,6.0.1 just flash.
2,after flash developer firmware dont let phone boot immediately go to download mode and flash twrp recovery.
3,after flash twrp recovery flash sprintxnoteRC2 kitkat rom this will boot flawlessly to kitkat.
4,if you like to try other n910p based kitkat roms go to twrp and backup (boot) thats your kernel of sprint xnote RC2 rom before flash any kitkat rom cuz i donno somehow kernel of sprint xnoteRC2 let boot every rom successfully without any errors.just after flash any rom immediately go to twrp restore and restore (boot) kernel that you made earlier from sprintxnoteRC2 rom.
4,FOR UNLOCKING download SSU APK this will work with kitkat if your phone says INVALID SIM CARD just install as normal APK and open it will ask for root permision PRESS GRANT and unlock then reboot if still your phone dosent get signal bars then go to dialer and dial ##72786# and press YES it will reboot automatically your phone and hopefully you will have signal on gsm sim. if SSU apk method does not work download gt galaxy tools apk and unlock.grant root permission to galaxy tools and open app go down and you'll see UICC unlock just hit and restart device . also you can unlock tethering hotspot permanently from galaxy tools . THATS ALL. I AM SHARING YOU GUYS MY EXPERIENCE I HAVE TESTED THIS METHOD ON MY DEVICE AND i HAVE SUCCESSFULLY UNLOCED MY N910P AND DOWNGRADED FROM 6.0.1 TO KITKAT

I MADE THIS THREAD SPECIALLY FOR NETWORK LOCKED N910P USERS TO TEMPORORY DOWNGRADE TO UNLOCK NETWORK. BUT IF YOU END UP USING KITKAT ROMS THE FINGERPRINT SENSOR WILL NOT WORK.
FIX FOR FINGERPRINT
Flash og5 5.1.1 bootloader only along with with Nadia 4.4.4 kernel flash in twrp and you get everything working with any kitkat rom.
Or flash 5.1.1 6.0.1 stock firmware the fingerprint will work fine and unlocking will stick permanently
HiT THANKS:good::good::good:
Can I go back to a non-rooted, stock KitKat ROM without tripping KNOX?

Can you Odin any firmware after this?
If so, this is a game changer for kitkat lovers.
You can upgrade again to 5.1.1 & 6.0.1 n910p firmware but you cannot flash n910p official kitkat it will simply fail in odin.you can flash any kitkat n910p roms in twrp recovery with diffrent kernels also i have tested deodexed 4.4.4 n910p based rom and it works flawlessly with custom kernel .i have tested everything every firmware but sadly 4.4.4 n910p fail in odin .
Which kernel is it in that SprintxnoteRC2 rom? Any other kernel working with KitKat?
Ael kernel.

Ael kernel
how long has this kitkat developer firmware been leaked?
and can't you downgrade to official kitkat from the oldest 5.0.1? most of the "first new OS upgrade" won't block downgrades
6.0.1 --> 4.4.4 dev --> oldest 5.0.1 --> 4.4.4 official
edit:
also, does the dev firmware format internalsd like PB5?
Does the unlocking persist when upgrading to newer firmware?
Returned from PG1 to NK2 ( BoBCaTROM v2.0) following OP's tips. Since the purpose of flashing the dev tar is to update bootloader, I deleted the system file from the tar ball and ended up with a smaller file about 130 MB
download here.
From the attached screenshot we can see, the modem is AOF1, the kernel is AEL 5.5 (which is not shown in the screenshot).

This dev firmware i found accidently from a Chinese website they use to refurbish and spoof usa models to international models and resale again . I tried to flash official 4.4.4 but it fails in odin.its something to do with this developer firmware that it can let us downgrade to 4.4.4 .anyway you can use this dev firmware to downgrade and flash kitkat custom roms and kernels.
Binary invalid

With system partition removed as mentioned in my earlier post. After all, bootloader is all you need.

Hmmm... After flashing this firmware, without rebooting and going into download mode, one has to flash TWRP & then any Kit-Kat based custom ROM. Got it! :good:

Hi, I meant SGH-i337 in the title.
I beleive I posted this in the completely wrong phone section last time, so I am posting this here.
My device model is the SGH-I337. I downloaded Odin version 3.12.3, downloaded the official drivers for the Samsung S4 USB, but I can't seem to find stock Lollipop 5.0.1. SamMobile only gives the 4.x versions for some reason. I started following the below link for a method to at least flash an older firmware to my phone, but I want to flash stock Lollipop. Is there even a way to get Lollipop back without root?
https://forum.xda-developers.com/galaxy-s4-att/help/guide-att-samsung-galaxy-s4-sgh-i337-t3383078
I was able to downgrade, but I still need an official stock 5.0.1 firmware. My virus protection says towelroot is a virus, so I don't want to go that route. If I do an OTA upgrade after I flash the old firmware from the above link, will it brick my phone? It's rootable NB1 ROM. I already tried to install the stock 4.x firmware from SamMobile, but that doesn't work, so it seems I need stock Lollipop.
AT&T never released a stock lollipop firmware that can be flashed with Odin. All at&t updates were released ota.

Hi I am running goldeneye custom rom on my i-337 5.0.1 with ok2 kernel. If you go to that forum thread in development, you will find very detailed instructions to get att s4 to 5.0.1 stock. As a side note I can assure you if you just download towel root on your phone, install and run there is no virus of any sort. Make sure you download from towelroot .com
On second look through I don't think there is stock 5.0.1 using safestrap....
