Doomed to be in lollipop 5.0 - Galaxy S 5 Q&A, Help & Troubleshooting

I used to be happy with my 5s SM-900M back in 4.4.2 kitkat.
My days started to be so awful and sluggish with this update.
Now I can't downgrade my phone to kitkat, because SAMMOBILE site downloads last forever with 15kb/s download speed.
Anybody here with an unbranded SM-G900M firmware?
I made a fully backup from my 4.4.2 stock rom, (boot, data, system, efs, cache)
Would I brick my phone if I restore that backup?
Thank you guys.

no but you have to downgrade the bootloader and modem right after restoring via cwm or you will brick it :fingers-crossed:

[Q] Reverting back to your original firmware

I've just flashed Echoe 2.1.1 rom over my I9505 and later there is a new firmware update from Sammie - MI1. Will I brick my phone if I flash the new official firmware using Odin? Are there any method where you can safely downgrade to your original rom?

You can Flash Stock firmware using Odin I don't see any issues and if u have a nandroid backup of your old ROM that will also work just fine
B4 doing anything if u have not done Do take a efs backup and nandroid backup and keep it safe somewhere on Pc/ Sd card
and after flashing Stock firmware I suggest full wipe / reset for error free experience

Hello,
Yes it is possible to downgrade from an official Molitor to an official kitkat (the latest).
I do it, when the flash is end and the mobile show the logo Samsung
You can put out the battery, reboot to the recovery and wipe all user data.
Before do that save all your data.
It's an official administrator from Samsung who say me do so.
Hope that can help you.

what do you mean by the kitkat (latest) because not all country have the same latest version.. like in my case my mobile is originally from KSA. and i think its not the latest kitkat out there.

Isn't the bootloader required to flash the ROM?
I'm very afraid of trying stock lollipop. I was on Temasek's CM12 build but I had abysmal batterylife. This was probably not attributed to Temasek's build but rather to CM12 as a whole, so I went back to my nandroid containing Crash Rom V19 on kitkat 4.4.2 and I literally have less than 1% drain per hour with the phone idle. I love this batterylife, and I feel I'd like to try and see if stock lollipop TW will give me the same but I would like the option to go back to kitkat if it's worse. I like lollipop a lot but the promise of batterylife seems to hit and miss, makes me stay on kitkat.
I know Crash Rom has a lollipop version, but beside this, which ROM is the MOST stock with the least amount of modifications?

[N910F] Downgrade from POF2 to ANK5?

Is it possible to downgrade the N910F from Lollipop (POF2) to KitKat (ANK5)?
YES, IT IS POSSIBLE.
Before yesterday I've never used KitKat on my Note4.. When I bought the phone I had no time to try it (KitKat) because I've straight rooted it and flashed a Lollipop based ROM.
Then yesterday I wanted to try a KitKat based ROM and I've lost about 30/40min looking in the forum for the answer to the question Is it possible to downgrade the N910F from Lollipop (POF2 or whatever) to KitKat (ANK5)?
I could not find a proper answer.. there was this BOF5 bootloader can not be downgraded but it was always in a "strange contest" and it did not convinced me.. after 30/40min I said ***k *t and I just performed a full wipe from TWRP, flashed ANK5 modem and bootloader via ODIN, and installed the KitKat ROM from TWRP.
Sorry for the Question/Answer but this thread may will help someone to save time.
P.S.: My KitKat adventure lasted only 10min... It looked ugly to my eyes! Went back on POF2 and now trying out AICP

When you flashed that lollipop-based rom, that was a custom rom I assume? Did it contain a bootloader? Maybe you were still on the KitKat bootloader.

Yes, it was a custom ROM. No, it didn't contain bootloader. No, I wasn't on the KitKat bootloader, for sure my bootloader was POF2. Trust me if I tell you that before the KitKat ROM I've flashed too many Lollipop ROMs with many Lollipop bootloaders.
I'm trying to do this but i fail in every action at odin with this SW rev. check fail. device 2 binary 1 in my SM-N910C and in odin its fail... ( i gets this after recovering my phone at kies after a bootloop )

Downgrading

Hi, My cell is on LP 5 but i don't like it, can i isntall any kitkat rom without flashing the kk firmware, if yes how
thx
I think that yes. I flashed on my G900F Miui based in KK and it worked on LP firmware
Lollipop Update Blocked downgrading.
It's not going to work. I think that using a nandroid backup made by somebody else should work.

Question on 5.1.1

Quick background. So my note 4 is currently on 5.0.1 boe1, stock rooted knox flag tripped so I cant update via OTA to 5.1.1 which is fine, I'm already readying myself for a manual Odin update
Question is that if there is a 5.1.1 firmware avail on my country for my provider, if I flash the stock 5.1.1 firmware does it also flash the 5.1.1 bootloader or will it retain my 5.0.1 bootloader? I'm pretty sure it will also update the bootloader but wanted to ask anyway to confirm.
Main reason for asking is that I know you lose root when you flash stock firmware via Odin. I'd still want to attain root after upgrading to 5.1.1. Not sure if there are any methods to date to root on 5.1.1 bootloader, or if its safe to flash the 5.0.1 bootloader after the 5.1.1 stock firmware flash.
TIA for those who would answer. [emoji1]

Simple bro. Don't forget to backup your data!!!
Poland 5.1.1 comes with 4 files including bootloader, modem, csc and system. Country or provider means nothing for it, it will work anyway. So, here are the things you gonna do:
1-) Flash Poland 5.1.1 with odin (be careful to place all files in correct section in odin!!!)
2-) Enable usb debugging from developer options
3-) Flash twrp with odin
4-) Lastly, flash which 5.1.1 rom you like, all of them are rooted now :good:
Bumping up since 5.1.1 is already avail on my country. Wanted to know if flashing the 5.1.1 firmware would wipe the device or will it be just an upgrade.?Haven't tried flashing an official firmware on top of an official stock (lower version).

It won't wipe your phone data, it will be like an upgrade.
Secondly tripping knox does not mean you will not receive OTA. As long as you are fully stock and when you check the system status in settings and it states 'official' you will receive the OTAs

Thanks! Yep, realize that now. I believe the reason I can't receive OTA is due to the custom recovery I've installed. Will try reverting to stock recovery first to see if I can OTA upgrade. If not, will download the full firmware and flash on ODIN.

The ROM might still consider your device to modified, You may have to flash stock from Odin and then check the status, if it still says modified then a factory reset might be required.
