Hello to all. I want try lollipop but, if I don't feel good with this, I want to reverte back to kitekat custom rom. So the question is... It's possible to downgrade to 4.4 custom rom with baseband and radio of lollipop?
Thanks in advance

Unfortunately, you need to flash the KitKat bootloader and modem before you can return to 4.4.
The files are here, under "Installation", step 8.

Ok. So if I flash back a stock 4.4 it's possible to downgrade completely to this? Or Odin can't downgrade baseband and bootloader?

Yes, if you flash a stock 4.4 image, you don't have to do anything else.
will you lose data and apps if you do this ?

What is the difference between devices hltetmo and hltecan? I have a hltecan. Will we need CyanogenMod compiled for hltecan? I notice that recoveries have different versions for both devices. Also I am wondering about downgrading for 4.4 (when it comes) to 4.3. Is there a surefire way to upgrade and downgrade between 4.4 TW 4.4 CM and 4.3TW? I would not mind voiding my Knox counter. Just worried about being stuck or getting a brick for another 21 months on contract :silly:

Sigh. I would do anything to be able to upgrade and downgrade between versions. Even Knox counter. If anyone finds something let me know

I played around a bit earlier... The only firmware you can upgrade to 4.4.2 and downgrade back to 4.3 is the mexican telco one for the n900w8, however I had some issues but will play some more tomorrow when I get time. As for KNOX, it's just one of them things we have to live with I'm afraid..
EDIT: I'm gonna mess with the bootloader and see, doubt it can be matched/mixed to work with the N9005 but what's the harm in trying.

The harm in trying is a hardbrick.
Well yes there is that, however I am not overly fussed about it, as most HB's can be revived. I am aware of all the risks, so will be my fault 100% if I brick myself.
I upgraded my note 3 yesterday to android 4.4 with cm 11, using the probam rom.
I noticed that it lacked the s pen features, so i downgraded back to stock rom.

Flash a tar.md5 through twrp? What version of the stock rom?
Did you have the new bootloader?

CM is based on MJ/MK Bootloader. You could run Android 9.6 and it'd make no difference. It's all about the bootloader

Sorry. Can't understand exactly. What exactly means what versions you can run with a new bootloader?
MJ7 is the bootloader that powers CM currently. You need a bootloader to be able to boot into the operating system. Like a key into the phone.
If you upgrade your bootloader to a newer version aka NA6 it locks the phone. Therefore anything that runs lower than NA6 aka MJ7 won't work.
Think of it like, you broke your door, you got a new door and tried to use the old key. It no long works.

I know how bootloaders work. Isn't there a way to omit bootloaders from Odin tar.md5 updates? Once I/Someone figures that out I'm golden staying with my old bootloader. Currently on MJ1.

hi, can you elaborate?
i always thought samsung doesn't let you downgrade to an older bootloader. but if you install CM (not samsung official updates) the bootloader doesn't get updated so you can downgrade in the future.
unless you upgrade to 4.4.2 official samsung ROM and update the bootloader, then you'll never be able to downgrade again?

No, if you want to try out kitkat i recommend you to use a cyanogenmod based 4.4 like probam, it doesn't update your bootloader and you can just downgrade back to jellybean

I've spent a week trying to upgrade to lollipop. Finally got it done today and hated it. Tried to downgrade back to 4.4.2 but didn't work.
I'm currently sitting on the samsung colored screen that bootloops. I get beyond the white boot screen. I have twrp 2.8.5.0 installed and working fine. I tried to nandroid restore a 4.4.2 but thats what put me in this bootloop. Any suggestions?
Yes
Update your Bootloader, So you can go to Recovery and Wipe Everything except the External Storage, and try flashing the rom.

NO, a nandroid backup does NOT contain bootloader or modem. They must be flashed separately, see the thread below for download links, flash in odin
http://forum.xda-developers.com/showpost.php?p=52210611
wow thank you, didnt know that.
ok so it appears g900az bootloader can't be found on the internet that i see. can i extract it from a stock rom and flash it on its own? i'm thinking that i cannot go down to 4.4.2 from 5.0 on the stock rom.

wait, in TWRP you can include bootloader and modem. I always do this. After using this nandroid to restore, it does not seem to restore the bootloader as I still have the 5.0 bootloader.

Modem yes bootloader no. When you see the option to backup "boot" in TWRP that is the boot.img which is NOT the bootloader.

interesting, thank you! i went ahead and installed a decent 5.1.1 rom since i needed xposed. so far so good, but i do miss my 4.4.2. i could not get any bootloader to flash for my g900az even the 4.4.2 odin rom.

Are you sure I can just flash overy the stock lollipop romantic because I have to try downgrade back to kitkat and it's been trial and error
I have successfully downgraded from 5.1.1 to 5.0
I seem to remember reading once you go to 5.0 you can not downgrade to 4.4.2. Not 100% sure though.

Yes, you can downgrade to 4.4.2, you only have to downgrade your bootloader to use an 4.4.2 android version.
If you are already using an 5.0 Bootloader version, when you try to flash an 4.4.2 android version you get into a LOOP - BOOTLOOP.
Even i didn't know about that thread. Thank you for posting it.

I'm confused by your reply so please clarify. You say you can downgrade your bootloader to 4.4.2 but then your next sentence says if you are using 5.0 bootloader and flash 4.4.2 you get a boot loop. That is my experience also, are we having a translation issue here?

Because from what i researched, the G900AZ came already with an 5.0 Bootloader. Dunno if i got that wrong, but i understood that.

ok that makes sense. my g900az shipped with 4.4.2 a long time ago. i just now started to upgrade it, but didnt realize xposed only worked on 5.1 not 5.0, so it took me awhile to find a 5.1 rom that was good enough. i like stock odex'd roms with xposed. thats hard to find, and custom roms are just too custom for me.
