I am on a quite old bootloader and modem as I have not ran any new Roms, or updates to my phone in quite awhile. I was going to try out a new 5.0.1 rom (I am on 4.4.2 now) and was not sure if I would need to update my modem and/or bootloader before I do so.
On SamMobile there is certainly new firmware for my model and carrier, so I was considering flashing the modem and bootloader thru Odin before I try a 5.0.1 rom. Is this recommended/necessary? By flashing a new bootloader, will I lose root or my ability to flash custom roms/kernals/etc?
I tried googling and searching on here first, but could not quite fine the answer. Thank you for any help or guidance.
If you're going to flash a 5.0 touchwiz rom it will update the modem and bootloader I think.
Updating them is not necessary.
People say that flashing newer modems will give you a better signal reception. I have yet to see that "better" signal reception.
You won't lose the ability to flash stuff.
You will only lose root if you flash a stock Samsung rom.
Can it is possible? I have official firmware of jellybean dwnlded from sammobile.
Help.!
Not possible as the Knox-enabled bootloader prevents downgrades. Even if you were able to downgrade, say by perhaps not downgrading the bootloader while downgrading everything else, it's unlikely the radios on the device will ever function. About the only use there is for such a downgrade is to carrier unlock the S4 using RegionLock Away, and even then you only have to flash a modem to do that.
Downgrading to Android 4.4.2 should be possible, if you really want to. I'd recommend flashing a custom ROM instead. All the custom ROMs, regardless of whether they are Touchwiz-based, GPE-based or Cyanogenmod-based, all include the battery drain bugfix that stock ROMs lack.
Thanks but i dont want now bcz voltaqe kernel has solved my problem i.e sound gain
Excellent! Good to hear you got things resolved.
I'm coming from 4.4.1 I want to flash a Lollipop ROM, I haven't flashed for very nearly 2 years. I'm obviously rooted already.
Is coming from KitKat as simple as just flashing a Lollipop ROM? I'm an SM-9005, I've got Odin 3.10 and I want to flash Resurrection-Remix-LP-v5.5.5.
I've seen that I need to backup my PIT and obviously backup my current ROM, do I need to update my baseband or radio etc?
No one?
No need to backup your baseband or radio. RR is an AOSP ROM as far as I know, so you won't be able to flash it with Odin I'm guessing, as it comes as a zip package? I don't have any interest or idea about it, but you can only flash via Odin if the ROM comes as tar image.
Also as you are coming from KK, you 'might' need to flash a stock Lollipop ROM first to update the bootloader from KK to LP, read RR topic, see if its mentioned or not. If its not then you probably don't need to, but as I said no idea.
Hello friends now my gti9505 have custom lollipop rom.UHOJ2 base modem and bl.one suggest me can I flash custom kk base rom?any problem after flash kk base modem bl over on lollipop modem and bl?
Yes it will probably work.
Be sure no problem about baseband and imei lost?

A custom rom never contains a modem or bootloader. So no that does not apply.
It mean no any problems after flashing?
Some custom ROMs require an up-to-date modem and bootloader. If you flash a custom ROM, the imei may disappear or wifi/calls may not work if the ROM is too new for the phone's bootloader and modem.
Before installing a custom ROM on a phone, I make sure that the phone is working properly with the latest stock ROM.

He means it the other way around. He wants to use a kitkat rom on a lollipop bootloader and modem. That's shouldn't be a problem.
I see the OP asking 2 questions:
1) Can a KK ROM be flashed to a phone running an LP bootloader and modem. Generally, I would say yes but whether all functions work will depend on the KK ROM. Some custom KK ROMs I ran on my Nexus 5 required me to downgrade the bootloader and radio to KK versions.
2) Can a KK modem and bootloader be flashed over an existing LP modem and bootloader? I think it depends on the phone's installed bootloader.
Yes audit13 brother my quistion is no1. I have now albe95 astra v2 on UHOJ2 base modem and bl lollipop. And goes to goldfinger kk base.now confused what can I do?
Did not try on i9505 but it works on i9500. I think it will work but u should backup your EFS partition
I say try the KK ROM on the LP bootloader and modem. If it doesn't work, you'll either have to find another ROM or you'll have to try and flash a KK bootloader and modem over a LP bootloader and modem.
N910T TMOBILE NOTE 4 IS ALMOST IMPOSSIBLE TO DOWNGRADE TO OFFICIAL KITKAT BUT AFTER LOT OF RESEARCH I FOUND WITH N910T2 KITKAT FIRMWARE IT'S POSSIBLE AND I HAVE TESTED IT 100% WORKING.
YOU CAN DOWNGRADE DIRECTLY TO N910T2 KITKAT FIRMWARE NO MATTER YOU ARE ON 5.0 5.1.1 OR 6.0.1
JUST FLASH WITH ODIN N910T2 KITKAT FIRMWARE AND WIPE DATA FACTORY RESET AND WIPE CACHE IMMEDIATELY AFTER FLASH.
N910T2 FIRMWARE RUNS FLAWLESS ON N910T AND NO BUGS AT ALL EVERYTHING WORKING 100% EXACTLY LIKE N910F INTERNATIONAL VARIANT. NO TMOBILE APPS BLOATWARE NO TMOBILE BOOT ANIMATION OR SHUTDOWN ANIMATIONS NO WIFI CALLING.
DON'T TRY TO FLASH OFFICIAL N910T KITKAT FIRMWARE AFTER DOWNGRADE IT WILL NOT WORK I HAVE ALL READY TESTED IT.
NOW YOU CAN ENJOY KITKAT AGAIN WITH AMAZING BATTERY LIFE AND SPEED ALONG WITH CUSTOM ROMS LIKE DYNAMIC KAT, FIREKAT,INFAMOUS ETC.
YOU CAN FLASH AND ENJOY ANY CUSTOM KITKAT ROM WITH TWRP AND NADIA 4.4.4 KERNEL.
PLEASE NOTE-_- WIFI CALLING IS NOT SUPPORTED WITH N910T2 FIRMWARE .
IF YOU WANT WIFI CALLING FLASH ANY N910T BASED KITKAT ROM IN TWRP WITH NADIA KERNEL.
THIS METHOD ONLY FOR N910T T-MOBILE NOTE 4
IT WILL NOT WORK ON N910T3 OR ANY OTHER MODELS.

There is no n910t2 marshmallow or even lollipop available anywhere else.i search all over but only 4.4.4 kitkat available right now.

Yesterday i was messing around to downgrade from marshmallow to kitkat on my n910t but no luck since our locked bootloader but accidentally i downloaded n910t2 firmware from sammobiles.com and i thought i give it a try and guess what i fully downgrade to kithat without any errors in odin and firmware runs flawlessly on n910t everything works expect no wifi calling i think n910t2 is a modified firmware for those who dont want tmobile crap and bloatware the only issue i face when phone boot up is the playstore was lagging but after an hour phone settle down and works awesome 4glte and signal works great .remember no wifi calling supported in this firmware and your model number will change to n910t2 even tmobile boot animation logo not exist. It looks and run exatly like international n910f 4.4.4. After i downgraded i flash twrp and flashed drketen 4.4.4 rom and it works flawless so i did try to flash firekat and dynamic kat but they did not works with n910t2 bootloader.and also 1 thing i want to mention that i easily upgraded again to 5.1.1 dok2 and 6.0.1 epg2 firmware so no worries to switch back.

after flashing the 910t2 firmware to kit kat, did you try flashing the regular 910t 4.4.4 firmware over it?

Yes i did but sadly it doesn't works. I am preety sure that bootloader is not locked since i was able to downgrade by n910t2 kitkat firmware .Maybe tmobile put some kind of code thats why we cant downgrade to n910t kitkat .anyway atleast we can downgrade officially without rooting to kitkat at this point.but i am still trying to figure out if i can flash offcial n910t 4.4.4 firmware.
Hey bro..do you know how to extract the tar and make a baseband and BL only tar...it would be alot easier than downloading the whole firmware at 15kb a sec ha...if not I can do it if someone can upload the firmware to mega or drive

Download link to mega uploaded in thread.
It's not really I guess...it just makes it easier for anyone wanting to try it...because using a kk rom and twrp recovery you only need the baseband and BL...and it's less of a chance to mess up efs or something than when flashing the whole firmware

Yea i did try to flash ank4 but odin fails . You can downgrade to n910t2 kitkat bootloader but not n910t kitkat or even 5.0 lollipop odin will simply fail every time i donno why but good thing is somehow you can still enjoy kitkat.i am running kitkat n910t2 firmware on n910t and everything works perfect wifi/data/xposed/all sensors nothing is broken only wifi calling missing and battery life ofcourse kitkat is best. You can still flash kitkat roms but only international n910f ported kitkat roms i guess but you can try with different kernels if you wanna still use ank4 base roms .

Do you know it works ? I think not because the logic of not allowing older bootloader is in the phone and not in Odin

I heard lot of good things about FireKat 4.4.4 rom , that is why i wanted to do this whole process of downgrading.
I don't know if it would work. I'm on a W8. Wouldn't hurt to try.
