UPDATED BOOTLOADER POSTED.



********************** THIS IS A TEST FIRST. DO NOT, I REPEAT DO NOT TRY TO ODIN THIS BOOTLOADER IF YOU ARE NOT EXPERIENCED. BRICKING YOUR PHONE, FLASH FLOODS, AUDITS, AND EX-GIRLFRIENDS KEYING YOUR CAR ARE NOT MY FAULT. YOU TRY TO ODIN BL OF YOUR OWN FREE WILL. **********************************************

ANY WHO,
Can somebody please flash this via Odin and make sure that it finishes the process. I'm still researching to see if you need a pit to flash the BL by itself.

THanks guys.

I'm getting stuck at the first part sli.mbn, but i already have the updated bootloader. From what i've been reading, this new bootloader my not let you downgrade as it's locked (or partially locked, not sure)

So somebody on old baseband looking to upgrade to new baseband should try this out.

It's not locked. It's rollback-protected.

Read this whole thread and you will understand why (except in a few unique situations) you cannot downgrade the bootloader: http://xdaforums.com/showthread.php?t=2642207

Upgrading the bootloader and stock ROMs is a one-way street for the majority of us.

I think the focus is on the wrong thing . Everyone wants the modem not the bootloader. And from past experince with note 2 specifically the modem was made into a flashable zip.

no,

some of us need the updated bootloader because the current wave of custom kernels doesnt play nicely with wifi calling and you cant run a KitKat kernel without the KitKat bootloader

OK, people have been asking me for this, and I said I would extract the Bootloader and post it.

I don't know about Wi-Fi calling but you can run Kitkat kernels with the old bootloader. Everything seems fine to me.

Would like to run the new modem if possible on the old bootloader.

If I have to update the bootloader to run the new modem, then I will do so...but MY main desire is to have the new modem. - I run AOSP, and those all work for either bootloader.

i'll look into the flashable modem then sense people only want that. still trying to figure out why forcing the bootloader is not seeming to work

would like to see this bootloader working as I am planning to flash 4.4.2 via mobile odin and this bootloader via odin pc and hope that knox is not tripped while retaining root. Currently on 4.3 rooted with RDLV.

    BTW, I just went through that blog article (translated by google) and it reads like the other "keep root" 0x0 update descriptions I've seen using Mobile Odin Pro and Odin (or in my case, probably Heimdall) - with the exception of the part where you have to repackage the bootloader, of course :). Thanks for going through that process for us!

    On the international / 9005 threads, there is a modem update along with the bootloader update; it contains modem.bin and NON-HLOS.bin. Those two files are also present in the 4.4.2 update that I have for the N900T. Think it's a good idea to extend that post's method to make a modem.tar.md5 that's flashable along with the bootloader?

    EDIT:
    I can make the modem package, once I'm home and have access to a Windows VM.

    Think I might try this method tonight, too; I'll report back here if I do.

    Success!! (with small caveats!)

    First, for the overall method - SUCCESS!!

    I started on 4.3 MI7, and I am now running 4.4.2 with baseband reporting ...NB4, build number …NB4, and kernel build date (12 Feb 2014) consistent with KK update - all with knox flag still happily at 0x0. Awesome!

    Here are the caveats: I did the Odin part using Heimdall, which flashes each partition individually from separate files; I used files from the stock 4.4.2 release for N900T, and flashed all 5 bootloader .mbn files as well as modem.bin AND NON-HLOS.bin - all to their respective partitions. Heimdall downloads & uses a .pit file, so it knows where things go. I think this suggests updating both bootloader and modem, and that the modem package should have both modem.bin and NON-HLOS.bin inside - though I can't say 100% certainly.

    I also used a deodexed, pre-rooted KK ROM to flash from Mobile Odin Pro - it's on the forums here, in the Android Development sub forum for 900T. In theory using the stock FW + ever root as per the German article should work too, but I used this one since I had it and it was already deodexed with knox and CIQ stripped out.

    So - happy to report success with the method (should I post a how-to?), but everyone should be aware that I didn't follow it to the letter for my own reasons and so I can't report on the exact protocol discussed here.
