Hi guys, I notice that there are official firmware files for download, such as "FIRMWARE-063-X00T.zip" (the latest official firmware from Asus).
Are these files of any use to me if I'm using custom ROMs?
Also, don't I get the latest firmware if I put the latest stock / official ROM back on my phone?
And if I install a custom ROM, won't that wipe out the official firmware?

Hi,
On my S5 (SM-G900FQ) , there is original Samsung ROM (4.4.2) , rooted but with default Recovery.
I want to update to new official rom (Lolipop) and then re-root.
What is the most easiest and convenient way to achieve this ?
I can update to Lolipop rom through Odin. But then how can I get back root easily ? (without installing CWM if possible)
If I have to install CWM, which version should I use ?
Thanks.
I'd appreciate any help. There are lots of threads talking about root'ing but I couldn't find the one which works for Lolipop official ROM.
Hi,
Currently my baseband version is N9005XXUDMJ4. Do I need to update (modem etc.) for Android 5.1? I want to use Temasek's unofficial build. If yes, where can I get an up-to-date version that I can flash with Odin?
BTW: This is an Austrian phone.
Update to a lollipop based baseband is the best way for zero issues in future. Yes you can flash by odin, but if your system and bootloader is kitkat. Why not flash a comlete Firmware? Thats the best way..... there are lots of links @ " general" forum .called how to..... blabla lollipop und so weiter.
Thanks, found a link for updating modem and bootloader, but decided to download the full firmware from sammobile. I'll flash a custom rom immediately thereafter, though.
Hi guys,
I have the following official rom :I9505XXUFNB88
I only rooted the phone using towelroot with Knox 0x0. However after two years of using it and now loosing my warranty I would like to update my phone to 5.0 or even flash a custom rom 6.0.
Theres a small hiccup, I can't ota any update because it shows me an error when flashing. I bet it has something to do with towelroot.
Do you know how to disable it?
Many thanks!
Download a ROM from sammobile, using the device model, and narrowing down the results by country and carrier. Flash that ROM through Odin, as it will be the latest provided by Samsung. That will upgrade your bootloader and baseband to the latest versions. From there, download the latest TWRP recovery available (link in the AOSP 6.0 thread located in I9505 Original Android Development) and flash that through Odin. Then flash the custom ROM of your choosing.
I had to upgrade from a KitKat ROM, in which my firmware was (NC4). Since I had to flash a stock Verizon lollipop factory ROM my firmware has changed to ( N900VVRUEOF1). Does anyone know if I can flash a Custom ROM that has a different firmware ? or know of a ROM with a compatible firmware ? Thank You in advance.
Hey guys, i searched a lot, on google and xda, but i think i couldn't find the answer to my question.
I have the latest unofficial LineageOS 8.1.0 Oreo installed, with TWRP.
At home my phone is losing wifi signal every few minutes and then it reconnects again, as far as i know this was already a problem with stock Samsung ROM installed. Now, since i rooted and installed TWRP and LOS i ask myself, if there is a possibility to update latest firmware / modem / booloader without wiping the device, respectively flash the whole Samsung stock ROM with Odin and root / the device again?
To be simple: Is it possible to flash extracted parts of the official Samsung FW package with odin or flashfire to update wifi modem / firmware without losing data and wipe my installed LOS rom?
All i could find was how to do this with official rooted samsung ROM but not how to update with an installed custom rom?
Maybe somebody can help me out here Thanks in advance!
EDIT: I found that somebody made twrp flashable modem and bootloader files! Thatd awesome, you can find the thread here: https://forum.xda-developers.com/galaxy-s7/how-to/guide-onelatest-stock-fw-csc-root-t3702963

I think you can update the bootloader and modem without wiping anything. Just flash thru odin. I'm on a custom rom by the way.
