Can i flash a new firmware, using odin, removing the aboot, rpm, sbl2, sbl3 and tz files from the tar file?? leaving only the boot, cache, hidden, modem, non-hlos, recovery and system img files? will there be another problem?
or maybe make a cwm installable rom with the dsixda kitchen?
i want to try but afraid to brick my phone... just tellme if im in the right direction.
thanks
No, thats not possible. Official firmwares need the new bootloader. You can however flash any custom rom.
modem.bin also contains sbl and rpm
there are many other things related to Knox bootloader
Flash the custom or make your custom rom with kitchen
Hey guys! I have a query...
Now due to bad battery life since MJ7 firmware, I am looking for any possible way to downgrade back to MI5.
And I know that flashing MI5 in ODIN will fail because i have new bootloader and Warranty bit = 1 in download mode already.
However, i still have the nandroid backup of my MI5 ROM and before i flashed MJ6 in Odin that brought about new bootloader.
I also have EFS backup i made when I was on MI5 ROM back then as i know that modem will fail to downgrade and i will lose IMEI.
So the question, is it possible to restore my MI5 nandroid Successfully? Boot into phone and then Restore my EFS?
Or will there be something that stops this from working and likely cause a brick?

id say it would fail. but likely be a soft "brick"

Okay. Any other opinions?
The Nandroid backup won't overwrite the new bootloader, and will just error out. - you are stuck with the new bootload I'm afraid man.
EDIT: yes softbrick is likely.

Does nandroid backup bootloader? I thought it was just kernel, cache, system, data and recovery.
Not sure if it does or not, however bootloader supercedes firmware overwrites/backup etc.
Hi, guys!
There is on guy on 4pda that has bootloader with the following in Download mode:
Code:
Odin mode
Product Name: SM-N910H
Current Binary: Samsung official
System Status: Custom
Reactivation Lock (KK): OFF
Secure Download: enabled
Knox warranty void: 0
AP SWAEV: 0 (test devise)
I believe that this is test device, and accordingly to Note 3 story it can give a possibility to reset Knox Warranty counter. Could some one of gurus please advice how we can backup and share his bootloader?
Thanks a lot in adnance!
This may help to backup sboot and param. And maybe other can restore with it. But we must be calm. And wait for advanced help.

The only problem - it requires root. And I don't know yet if that guy has a root. Flashing root with Odin may change warranty bit. Any other idea?
Re flashing stock ROM will replace original bootloader.
I strongly NOT in favor of making backup of bootloader and restore using anything other than Odin. In world of flashing if anything is RISKY it's only and one bootloader. Also I don't believe any method of restoring bootloader other than Odin will work anymore on newer device. Either it will make no effect OR IT CAN BRICK device.
Also If anyone have boot loader with re engineering which reset knox warranty - I do not recommend to try UNLESS you must required to do it.
Say for example your device have something wrong and you needs to send to service station - still you can flash that bootloader if required isn't? Only condition when you cant flash bootloader is
-Faulty USB pin - Who cares for warranty ? It does cost couple of $ why we should take risk for complete device?
-Hard bricked with unable to boot to download mode - How samsung service station can find your Knox status in this condition?
So Flash such bootloader only you really need it when required with own risk.
Thank you very much for advice.
But on Note 3 there was procedure to restore Knox warranty bit exactly by flashing test bootloader with Odin. I just want not to loose possibility to have a solution... Of course, I will think twice before flashing that BL, but at lease we will have some data to explore! Isn't it?
Obviously it's marvelous thing to have possibility to reset knox but only thing I suggest is to use as only real needy case not for fun /experiment.

But why you need to copy bootloader? You can get it from stock ROM file too. simply unzip stock ROM tar.md5 and you will have it.
BTW exynos version requires only one file for bootloader sboot.bin

I need to copy bootloader from Developer Edition phone. That bootloader is unlocked. I have access to one of such phones, that is why all thiss mess
Oh ok got it now.

So - here is bootloader with param partition. If anybody wants to explore them - you are welcome!
This bootloader is from Test Devirce. It doesn't locked, so any unoficcial actions wit device doesn't affect on Knox Warranty Void bit, it is checked.
Who is going to test it? :laugh:
Is it possible to reset N910C device? Testers waiting for you??

Other file should be used for testing, not that. That file can not be flashed via Odin as a bootloader.
I will not post it, because it is a bit risky. And there some backup preparation should be done before flashing. But anyone who wants to be a volonteer - welcome in PM, please.
Well, unfortunately it does nothing. I tested and flashed it on my own device - bootloader has changed, but not to (test device) status, and the Warranty bit was not resetted to 0... But we tried!
I want to thank a man who helped me a lot - @A.S._id.
On Note 3 prosedure was.
* Flash sboot an param
* Reboot download mode again
* Flash stock rom of your region from odin
* Factory reset on stock recovery
* Boot system
* Again download mode
* Re flash stock rom
* Factory reset and boot
This was working on note 3.

Any news? Sorry for spamming. @Zer0r Did you tried to reflash stock ROM and as well reset factory as the same procedures with Note 3? Post some images from successfull changing Bootloader please. I'm curious to that bootloader too. Mine is 910C.

No news, bootloader from test device, which, as we thought clearing warranty bit, didn't clearing...
Here is bootloaders for flashing via odin, one from test device, and different from realise device, you can to try flash them and make sure...

p.s.
as it turned out - the test device has ceased to be a test, after he flashed stock firmware

Any update?
Hello Fellas, am posting here as I haven't found help elsewhere. Kindly Respond to my woes. I have a rooted Galaxy Note 3 N900 running official Lollipop with IMEI Null/Null and No Baseband version. The IMEI just disappeared totally out of the blue as no custom ROM has been flashed on the device!! This has happened 2 months after updating from 4.3 Jelly bean. With no prior EFS Backup here's what I have tried:
1. EFS Professional (backup&restore complete but no luck)
2. EFS Restore express ( backup.bat>Odin restore)
3. GSII Repair tool
After hitting no luck with the above tools and without any "/EFS mount errors" in recovery either and WIFI working fine, I came to a conclusion that most probably the EFS folder partition on my Note 3 is still intact and most probably this could be a case of a bad modem which would explain the loss of Baseband Version and thus the Null IMEI. So I tried flashing back to KitKat with N900XXUENG1 firmware and separately flashed a few modems compatible with Samsung's new EFS System: N900XXUENG1_MODEM, N900_XXUENF2_MODEM_CWM and also gave a shot at recommended N900_XXUENE1_MODEM_CWM.ZIP which seems to restore baseband for many users with this issue but this failed as well. After much searching I found a 4file_N900XXUGBNL8 Lollipop Firmware with PIT from Dev-Host, flashed all files in Odin&even repartitioned the device but still no baseband!!! WIFI&everything else runs smooth except the damn baseband/Null IMEI! Almost Exhausted my options...
Now I trust we have some informed members and developers here, NEED YOUR VALUABLE IDEAS HERE mates! Someone, anyone.....Thanks!
Have got any guarantee of the device?If so,send it to service ıf your guarantee continiues.
If you bought the device from another country,This may occur ıf you didn't register it.(In my country this is how it works.Turkey)
Or someone cloned your imei,check your imei ıf it is valid.
This is not because you upgraded your device to android 5.
If ıt was the case,you would have already faced the problem after just the flash.
I would say flash another modem
But,You say you tried flashing other modems.So no luck with that.
I had seen s3 with the same problem.I had flashed a modded modem.
It worked.I dont know if there is one for your device.
Briefly this is an imei/modem problem.
I don't know ıf the suggestions above help you.
I hope so.
Good luck.
try flashing stock rom from sammobile via odin. you need to backup efs folder everytime you flash a new rom, that's my opinion. may be wrong.
I think I used to had this problem with my Note 2 as well. If you come from 4.3 you should flash stock ROM Jelly bean 4.3 from Sammobile or Samsung-updates website. Then flash lollipop 5.0 over 4.3 when you can see your IMIE. Maybe it will work.
So. If u in L bootloader. U must! Flash the L modem that sometimes didnt get flashed by the odin while flashing stock rom. So just extract the modem.img and things for modem. Then just flash it using dd command or make flashable zip. Then it works fine. I have it on s4 exynos. That if i in L bootloader then even i install kitkat rom with L bootloader. U must still flash the L modem. K. Hope it works
1. İf you couldnt recover with efs professional , probably you've been lost your original imei files like nv_data.bin etc. and there is no backup...
2. So try to remake this kind of files with-again- with efs professional. But there is not so much info about this "creation" process.
3. I had the same situation. . . . And i'm still sorry. . . ( . . . The other solution is JTAG, more easy, cheaper in total and psychologicaly healty !!!)
GOOD LUCK....

Thanks for that but as I already said I was lucky to find a 4file partitioned Lollipop ROM with separate modem. Flashed that through Odin and even repartitioned the device but that hit a rock as well!

It's an old device, no warrants. Am indeed looking at the possibility of someone else allocating the IMEI to their device, though i doubt. But if that was the case shouldn't the Baseband at least be present?
Did you try downgrading to 4.3 with official stock files?
If not,give it a shot.

I have explained it earlier, Actually it is kernel. Newer kernel makes some changes on EFS partition and that changes can not be read by old kernel but in this case once you flash newer modem it will be solved. If your issue doesn't solved by flashing latest stock ROM then only possibility is messed up EFS partition and for that you must have a backup which was created when your device was normal. If your EFS partition is corrupted and you don't have backup then i think only option you have is to go to service station they can repair it easily. Though your device is not under warranty but you have official bill then still they can do it with paid service. Now a days samsung have changed policy and restoring IMEI they needs to do it online with samsung server (this information I got from service center owner in my city who is my friend and he did same for one of my friend)

Thank you Dr.Ketan for that information. You have been a great help to many. I have followed your posts about this issue and I feel there is still hope.
UPDATE:
I WAS ABLE TO RESTORE THE BASEBAND AND NOW THE IMEI IS GENERIC, READS 004999010640000. [/B] I was able to restore nv_data backup from /Efs folder and deleting bad nv_data. Here's what I did:
Using root Explorer in /EFS:
Deleted corrupt files;
nv_data.bin ( 18 April 2015)
nv_data.bin.md5 (18 April 2015)
Renamed backup files (dated 31 Jan 2015) to apply;
.nv_data.bak > nv_data.bin
.nv_data.bak.md5 > nv_data.bin.md5
Using ADB shell:
Code:
adb shell
su
umount /efs
mke2fs /dev/block/mmcblk0p3
mount -w -t ext4 /dev/block/mmcblk0p3 /efs
Reboot
However, the baseband and generic IMEI come&go across reboots and seems not to stick permanently. Any possible steps from here???
NOTE: Previously I have been able to restore Unknown Baseband and Null IMEI in Galaxy S2 i9100 using the above adb method (Code Only) http://www.selftechgenius.com/?p=284

I always have that problem when I downgrade to jellybean but solving it is easy. Just flash THIS modem file under the AP option Odin. Tell me if it works.

If flashing modem via Odin you MUST turn off the phone then start it in DL mode. Simply doing a 'reboot' into DL mode will not let the modem be flashed.
Hello all, I have a Total Wireless aka Verizon TracFone branded S5, so it's model s902l but it's g900v hardware with unlocked bootloader. Of course they never released any updates so I'm wondering if some will share a twrp backup of the newest, or if you believe another is better, their modem and bootloader for me I'd like to try it, worse case I restore my backup if it doesn't take.
Thanks

The Modems are located on the following thread.

As far as the Bootloader... you will need to be careful when it comes to that because you can permanently lock it up and, possibly, brick it too.
I'm not sure where any of the separate Stock Bootloader files are on the forum since those who, typically, need it installed back on the device normally just flashes the Stock Firmware via Odin.
I've got a feeling that you might possibly be referring to the Stock Recovery and not the Bootloader.

There's a handful of TWRP flashable ones in the OP of that thread.
The only reason that the thread title states "Odin" is because most of them are Odin flashable ones.
I'm one of the threads Developers and u planned on creating the additional Recovery flashable ones soon but, am just delayed a bit.
The Odin flashable ones are actually the preferred method for most members anyway because of the additional safety checks by Odin.

I'll look again but read on one of the posts that they weren't TWRP flashable? I don't have a computer to use Odin right now and last time I tried those very safety checks you mention prevented me from flashing 900v files to my 902l branded phone. Ended up with a read only modem for a bit for trying. Of course the only factory firmware available anywhere is older than what came on mine and what sounds like everyone else's branded phone so have to be careful. That's why I was hoping for a backup to try rather than flashing something, maybe I don't fully understand the process but thought it'd be a safer route?
Am I supposed to use one of the SS/FF zips?
Last time I was attempting to upgrade my bootloader and modem I was following a thread that was supposed to both upgrade those and unlock the bootloader of actual 900v phones. According to that thread SS/FF zips aren't compatible with TWRP because they work differently?
Well I tried the newest available zip, it took about 15 minutes to flash and said successful but baseband still s902ludu3aog2 so that didn't work... Still hoping to get ahold of a backup I can just restore it at least try, unless someone has another suggestion on how to get newer 900v modem and possibly bootloader on my 902l model 900v hardware?
So nobody is willing to share a backup of their modem and bootloader?!?!

I think, flashing a bootloader from another S5 variant is a bad idea, most likely you'll brick the phone. Prepare an unbrick microsd at least to be ready, but nothing is guaranteed.
I don't think you'll manage to flash modem and bootloader from TWRP because TWRP means Samsung's binary state: custom and these partitions are protected in custom state.
I think, your best bet is to revert to factory recovery, get Samsung binary: official, root the phone and use SS or FF.
Not possible, factory firmware doesn't seem to exist, only 1 does and it's older than what it came with from the factory. Also it's Verizon hardware, same FCC id, but different model and comes with unlocked bootloader. I don't want to flash anything, I just want to restore a backup.
I appreciate your advice but I already been thru all of this...
Flashing is simply not going to work unless there's a way to change my device model maybe?
All I really want is somebody with a modem and bootloader newer than KitKat to please back them up in TW RP and share them please.

If the hardware is physically identical I don't understand why running a bootloader meant to run on this exact Hardware would cause a problem?
But I'm primarily interested in an updated modem. Neither will Flash since there are no updated modems for this MNVO branded Verizon phone.
