I have a G930V running G930VVRU4BRC2. Is it possible to update to the latest firmware, G930VVRUACSF2, via Odin without updating the bootloader too? If not, do i have to stick with the latest in the v4 bootloader, G930VVRS4CRI1? Is there a reason I should not update my bootloader too? Like the ability to downgrade?
Thanks.
Trust me you don't want to update and to awnser your question I'm not sure but I am sure that the firmware itself has the bootloader number so by flashing from RS4 witch is bootloader 4 to RUA witch is bootloader 10 it would be impossible to downgrade just upgrade to a bootloader 7 and lower you should be fine

Hi,
I am on the latest stock NG1 Rom after upgrading with Mobile Odin Pro from NB7 which I had successfully rooted with Towelroot. Since MOP doesn't flash bootloaders I am still on the old NB7 bootloader and so far I am fine and don't have any issues. But I have 2 questions.
First, is it better to subsequently flash the new bootloader with Odin each time I upgrade my firmware with MOP and everroot? Are there any benefits to that?
And secondly: if I upgrade my old NB7 bootloader to NG1 now and later - if I get softbricked or smth - downgrade again to NB7 with Odin to reroot the phone with Towelroo,t will I trigger Knox because of downgrading the bootloader?
Thanks very much in abvance.
Its not possible to downgrade your bootloader. End of conversation.

Which means that if I upgrade the bootloader to NG1 and then try to flash with Odin the NB7 firmware with the old bootloader I simply won't be able to boot or get bricked?
Or maybe I can reflash the old NB7 firmware and then (without auto start option in Odin) flash the new bootloader right away to get the phone running?
For example: if you were on Android V4.3 you will be on the Jelly Bean bootloader. If you then updated to Android V4.4 your Jelly Bean bootloader will be updated to the KK bootloader. However, you can still run Jelly Bean on the KK bootloader. But you cannot downgrade the KK bootloader to the older Jelly Bean bootloader.
Hi, i bought a new Note 4 (European Version, 910F) and want to update to latest Stock Rom 5.1.1 without root.
If i install with ota, i will get latest rom with latest bootloader, but this bootlader is locked.
How can i install this without installing a locked bootloader? Can i install old bootloader and new rom? Maybe with odin? And after this block ota updates?
I want to keep knox 0x0.
I have a Zenfone 2 LAser ZE550KL with locked bootloader. Android 5.0 version installed. Not yet upgraded to Marshmallow.
Can we use that official unlock app to unlock bootloader and then upgrade to marshmallow through the OTA?
Is that possible?
the answer is yes but you will do it via manual mode you will not receive any OTA updates
Yes.... ^^
But for everything work well maybe after update,
Factory reset for best run
I have the same question; I have a rooted, unlocked bootloader (unlocked via Unofficial Method in this forum) ZE550KL 5.1 Lollipop. I want to upgrade to Official Stock MM Firmware ? How to do so ?
Does the PF4 ROM have an updated bootloader that might work better for MM rooms? I believe my bootloader is getting older if this is the case. I have an unlocked bootloader but I believe mine is from way back at this point which is why I'm wondering.
MM needs an MM bootloader. PF4 and PD1 have an identical bootloader, so download Phone Info - Samsung and check your bootloader version. What ROM are you running and what is your bootloader version?
I have a question since I watched the youtube video on how to upgrade my phone samsung s4 at&t to Oreo, but I read that I need a bootloader. Then when I read articles here in xda, mostly says that this phone can't be unlock? so How do I deal with this? Please explain simply because I am new in this.
If the phone is running an MDL bootloader, it may be possible to flash Oreo. If the phone is running a newer bootloader, the phone can only run TWRP and will not run Nougat or Oreo.

You cannot unlock the bootloader. However, if you're on the MDL bootloader then you can use an exploit called loki doki to install a custom recovery and a custom ROM. If you're on a newer bootloader other than MDL, then you are stuck with only booting custom touch wiz based ROMs and must use safe strap if on kit kat or flash fire if on lollipop.
Can you oden back to mdl if you are running NJ4.
does it matter id i upgraded to Kittkatt with a custon rom vs ota update on if the bootloader got locked? does goldeneye kittkatt 4.4.4 lock the bootloader?

No you cannot odin back to MDL, if you try you will brick your phone. It doesn't really matter how you update given your bootloader is locked (unless you're on the MDL firmware). Golden eye ROM does not lock the bootloader, no custom ROMS lock the bootloader.
