Everyone knows, even Google. You just have to invest some time and use the forum search, and you shouldn't ask the forum members to do the work for you!!!

[Q] Omega ROM 7.0 New Bootloader issue

Hi im wondering if anyone else is having this issue. I just flashed Omega rom 7.0 with no problems but then i flashed the new bootloader using Odin and it was successful too but for some reason when i check the bootloader version its still the old one.
I figured it out. Make sure to power down completely first and then boot into download mode and then flash thru Odin that way.

What is all about that new bootlader? Do I need to flash it? What has changed?
Thank you!
If you want to use the stock kernels you have to flash the new bootloader. Things like screen casting to a smart TV can only be done with stock kernels.

Note 3 - TWRP and Stock Recovery

Hi Guys
This probably a newbie question, hope somebody will be able to enlighten me on this.
Once, I installed TWRP on my Note3, can I still flash official note 3 rom (from sammobile) using ODIN? or it must be restored/flash using TWRP?
Also, once I restored/flash the note3 stock/ official rom - firmware, do I lost twrp and have to install it again ?
Thanks.
Yes. You can still flash the official firmware using Odin. And yes, you will loose twrp and have to install it again. And you posted in the Note 4 forum.
Thanks and sorry for posting on note4 section, I was confuse

[Q] Flashing Stock Rom by SafeStrap

Hello
I have a problem with flashing new stock rom "G900FXXU1BNL9_G900FXEO1BNL1_XEO" by SafeStrap on my at&t s5. I downloaded rom from sammobile it is a zip file but when i try to install it by SafeStrap i have a error
"NO MD5 FILE FOUND".
After unpacked zip file with rom, there is one file "G900FXXU1BNL9_G900FXEO1BNL1_G900FXXU1BNL9_HOME.ta r.md5".
Someone know how can i flash this stock rom? or How can i convert this file to flashable by SafeStrap zip rom?
If it is bad forum section please move it, no remove.
Thags not safestrap flashable, and its also for the g900f, att is g900a wich has a locked bootloader, so even if you flashed it properly(through odin) it wouldnt work.

I know that it is for g900f but with safestrap make specialy for at&t s5 most of roms from g900f and another models should work normally in my g900a.
Any sugestion how can i do this ?

Pretty sure that is untrue, thats not how safestrap works.

Im sure that it will be work...devices is the same... only software is another and lock bootloader in at&t. I can flash any another flashable zip from this forum and problem is that i cant search zip version of this rom.
I have one suggestion haw can i do this...
I read somewhere that from recovery of system it is possible to do flashable zip. Maybe somebode have s5 without lock bootloader and can flash this rom via odin and make zip for me?
Or maybe another way?
Thanks

No one has an att variant without a locked bootloader, they are all locked. Where did you get these other flashable zips? If it was for the att s5 android development, those werw made to be flashed in safestrap, I think ankther variant's roms can be flashed but im not sure how it all works and its not the g900f. Either way, from the g900f or not, like i said earlier im pretty sure you have to flash in odin, safestrap cant flash firmwares, and even if it could, this firmware is for the g900f like ive also said(its the lolipop firmware, no?) and so you cannot flash it because the locked bootloader prevents it.

I flash via SafeSrap rom called "Omega" from this forum and rom CyanogenMod 11...it was working normally and they are for g900f and works fine in my g900a.
Yes this is lolipop...via odin i cant flash because i have locked bootloader...only via SafeStrap and flashable zips.

I dont understand how thats possible, everyone thats tried that has just gottena soft brick, and for a reason, locked bootloader limits us to touchwiz based roms, and CM11 is AOSP based, so theres no way it would work, are you aure youre using an att variant?

Im thinking you did something that made you think you flashed it and it worked, because it is not possible for it to work, theres no "i dont know how it worked" it literally cant. As has been said in the other thread you started, you can flash stock roms from other variants as long as its tohchwiz based and is 4.4.2, you cant flash lolipop because that is 5.0, and you cant do firmware updates through safestrap. So the answer to your question is no, you cannot get lollipop on your device as of now.

Ok i undestand...im sure that i have had CM11(4.4.2)...
Maybe you know where can i find stock rom from g900f with 4.4.2 android..

Downgrade

Hello experts i would like to downgrade to 4.3 from lollipop how can i do it ? Im using cm12.1 now thank in advance
Sent from my SM-N9005 using XDA Free mobile app
If you're using CM12.1 with JB bootloader than find a stock rom and flash with odin. But it's hard to find a JB firmware now.
If using LP bootloader you can only downgrade to KK.
Dial *#0011# if it could show your bootloader version.
Else install samsung phone info from playstore and screenshot as below.
If i want to downgrade to kk i just flash the official using odin ?

There are many posts reporting they successfully downgrade to kitkat from lollipop. For error free use the same region/country firmware of your phone(check your phone csc). Did you ever flash lollipop on your phone? Because it doesn't means that if you're running cm12.1 your phone has lollipop bootloader. The last time i check it can even run with jb botloader.
Myself however would refrain myself from downgrading as it could take some efforts to recover in case it's unsuccessfull

urgent pls.is that rom fits to my galaxy note 4?
