SM-N910F > Bootloop // ROM Problems || Please Help

So.. hello.
Normally I don't come to forums to get help... but yeah. This is kinda bad.
I've got a little situation here.
I got my new Samsung Galaxy Note 4 (SM-N910F).
It was delivered with Stock 5.1.1.
First try:
I booted to the Downloader, fired up Odin, let it download the Autoroot.
Then I've got a bootloop.
Second try:
Booted into the Downloader, fired up Odin, let it install the 5.0.1 Stock ROM (Ending with 'BOB4')
It booted normally , then two things pop up constantly:
Something like "phone.xxxxxxxx.xxx Service crashed".
and "NFC crashed."
So I can't even unlock that phone.
Third try:
Booted into the Downloader, fired up Odin, let it install "N910FXXU1COI3_DevBase_alexndr".
Ended up in a Bootloop.
Then I tried to install the Bootloader aswell as the Modem and the Kernel, which are also in alexndr's Thread.
Ended up in the same Situation as the second try.
I don't no what to do anymore.
I'd really love to hear some help from you guys.
Greetings,

// It is a German Device from Telekom.

The third attempt was incorrect, that file is to be flashed from a custom recovery.
The second try might be because you did a dirty flash (Need to wipe data)
The first attempt boot-looped because in order to root in 5.1.1 you need a rootable kernel and the latest SuperSU (Not CF-Auto root)(Kernel is found in the Android Development thread)

Thanks for the response.
What can I do to get a correct working System back? (Theoretically, I got time and bandwidth.)
Since flashing the Stock ROM did not quiet work.

KNOX Flag is already 0x1. Means varranty is void, isn't it?
So I don't think they will help me.

I've already tried to flash TWRP via Odin, but I've never seen it.
Flashed recovery was for trltexx.
Getting to Recovery should be the same as getting to Download Mode, or?
Anyways. Will try it with tbltetmo and report back.
// Just installed the tbltetmo.
// Can't see how to get into the recovery.
// Am I missing something?

Update:
Just signed up at sammobile and downloaded the BOB6 (4.4 i think) for T-Mobile.
Flashed via Odin.
Seems like it does work again.
Currently its installing like 260 Apps.
Let's see.
// Edit: Nah. It got even worse.
// But I got a Recovery. So that's something.
IT ****ING WORKS NOW
Went into the recovery and cleared cache and data. (Kinda stupid I did not do it inb4)

Do a clean install in Odin. Since it came with stock android 5.1.1, then flash the 5.1.1 stock firmware in Odin. If you have a locked device of a specific carrier it will be even better to use the firmware made for that carrier only. And check the "Nand erase all" option in odin before hitting the start button to flash. That will erase all the data from ur phone and will do a clean install. Your phone must then boot normally. Also note that android 5.0 root file may not work for 5.1. Also check the model number before flashing.

SMG900A Stuck In Boot Loop

I need this fixed asap as I need my phone for school.. I have no idea what Happened honestly, I just restarted my phone and it started doing this. The only thing i recall doing is possibly disabling SuperSU on accident before I restarted my phone.
All I've done so far is download the stock firmware from SamMobile and attempted to flash it, but when i do i get an (auth) failed code from Odin, I've been searching for hours and haven't found anything that has helped..

If you have TWRP installed, try removing SuperSU via the file manager in recovery, or flash SuperSU again
The Auth! problem is likely due to you trying to flash an older ROM version than is installed, and the bootloader won't allow it
Tried clearing caches from recovery / factory reset?

Can you help with a newer model?

i don't have anything recovery installed, its jsut the normal android recovery. I thought about reflashing supersu but I'm not sure how without a recovery..

Have you tried the factory reset from normal recovery?

Lost count of the number of threads about bricked G900A and G900P these last few weeks
Something about the latest Lollipop firmware, locks the bootloader from downgrading, even to just an earlier version of Lollipop, and it's a nightmare to try and find ODIN flashable ROMs for the latest release
Right now, unless someone else can think of something, all I can suggest is either taking / sending it in for repair, or wait for Marshmallow to arrive, and hope an ODIN flashable ROM arrives for that
Might as well give flashing TWRP a try (via ODIN), I don't expect it will work, but if you could get custom recovery running, you might be able to flash a custom ROM
Another thread with a similar issue, you could try this, but I'm expecting the same Auth! error

Tried flashing TWRP with the same end result.. This is dumb really frustrating -.- is there any way to install Supersu without a recovery?

CF Auto Root, but it'll likely fail too due to the bootloader

II have been working on mine same model and it is because once you screw up ,which i did,the locked boot loader wont let anything by. a relative pretty much started the problem by flashing a ROM and erasing everything. this one wont even go into recovery. still wont give up until I figure out a way just because.......

Recovery for N900V 5.0 OF1 Build?

Hello all...I have to first say that I HAVE been reading A LOT before I posted this question but I am somewhat confused. I have an SM-N900V with the following details :
- Rooted with Arabic Tool
- Android 5.0
- Build OF1
- Bootloader unlocked based on instructions at http://forum.xda-developers.com/ver...l/official-note-3-verizon-bootloader-t3359370
I also have a SM-N900T for which I have been using CWM based recovery for many years and I am very happy with it. But I am not forced to change to the N900V and I have it rooted already but I am having a hard time finding the right recovery for it. I tried a philz CWM based recovery and it ended u getting the unit into a recovery bootloop so I have to flash the stock firmware from scratch and start again.
Can someone save me a few hours, and potentially more reflashes, and tell me which is the right recvery for this unit and how to install it? I am partial to CWM but I have read that it does not work. As long as I can take backups and restore them I am happy with TWRP. I have also read that SafeStrap is the only option. So again, I just need a straight answer so I can get this done.
Your feedback will be much appreciated!
thanks!

Did you mean "now forced" instead of "not forced" in the 2nd paragraph? The use later on of antecedent references such as "it" and "this phone" make it slightly confusing which phone you are talking about.

If you have unlocked the SM-N900V's bootloader, then a bootloop can be remedied by flashing with Odin only the partitions you need fixed, not the entire firmware set. This relieves you from having to re-customize a stock ROM and/or re-root. Moreover and more importantly having an unlocked bootloader means that your phone will no longer require blobs to be Sammy-signed: you can flash custom recoveries with Odin if you please. (You just need to learn how to create the *.tar.md5 files for Odin and you are in business - search for "Odin ustar md5")
So had you know that, you could have just prepared Odin flash tarballs for different recoveries and tried them out according to whim (It is also possible to flash a recovery from the rooted ROM as well, but you need to know how to escape from a perpetual failed recovery boot loop, I.e. : battery pull -> restart with VolDown+Home+Power -> Cancel)
I haven't ever put CWM on my SM-N900V, but can tell you that either the " hlte" or "hltevzw" variants of twrp should work just fine; as you are on OF1 firmware, the -4.4 versions should be used, e.g. twrp-3.0.2-0-hlte-4.4.img or twrp-3.0.2-0-hltevzw-4.4.img
PS Safestrap was the method of choice prior to bootloader unlock methods, and I believe does not work with OB6 or OF1 (possibly also NK1?).

As long as you are rooted and have the bootloader unlocked... Use Flashify to load TWRP which is an excellent recovery and does what you wish.

Need help upgrading bootloader and modem

I've gotten no help at all with this. Very unlike this forum. My phone is a kltevew, which is straight talks version of a g900v. I need help, there are lots of great looking Roms that require you to have mm firmware I'd like to try!

Not sure why I'm getting g no responses on this. Surely someone must know something... The only response I got was not only not helpful but jerky and obnoxious. Doesn't anyone know how to upgrade the firmware on my phone? (And no, google has no answers for me on this.. I look everyday)

Download it with samfirm http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647 (Model= SM-G900V Region= VZW) or from sammobile http://www.sammobile.com/firmwares/database/SM-G900V/ , do you know how to flash firmware with odin?

I do. Thanks so much for responding. Every time I try with Odin, a few different releases, it always gives me the error message fail. Can it be done with flashfire?

What stands in the log of odin when the flash completes?

Ill have to do it again to see... Be back in a bit!

I think it says FAIL! modem but I'll have to run it again... Brb

Last night I used flash fire to install firmware. That didn't get past the red Verizon logo, so I put twrp on it with Odin. Twrp showed it as dpd1, but it just wouldn't boot. So I wiped it once and flashed a ROM that requires mm firmware. Same thing, justbootloop. So I put stock back on it, then mokee 6.0.1. which works, I'm just not on mm firmware and all the great new roms are still unavailable to me.

Have you enabled the option to flash bootloader on flashfire setting?

What? No, I haven't... but do do right now. Thanks for the tip! Actually, where would I find it?

So would I do it in this order? Flash the dpd1 bootloader, then modem, them rom, then jrkruse patch? All in flash fire?

It's in setting of flashfire...but only do it if odin doesn't work because do it from flashfire is more riskiy...
1)do a backup
2)check the bootloader flash option
3)install the firmware with all the wipe except internal storage(it mean that flashfire delete /data excluding /data/media/0 (sdcard) but include it in your backup copy because you never know )
4)wait till reboot skip setup wizard "spamming" the next button then install the rom with flashfire or twrp
On the flashfire site i found this:
Flash bootloaders
"This setting controls if FlashFire will attempt to flash bootloader partitions. By default, bootloader partitions are only read and never written. Even when enabled, flashing bootloader partitions may not succeed - many devices have protections in place against the bootloaders being overwritten.
Please note that flashing bootloaders is extremely dangerous. Any bug, error, or failure may result in an unrecoverable hard-brick. Do not use this feature unless you know exactly what you are doing.
Due to the danger of this feature, it is automatically turned off every time FlashFire starts. You have to manually re-enable it every time you want to use it.
If you must flash bootloaders, it is advised to use a bootloader-based flashing tool such as fastboot or ODIN to do it, as these are the safest methods. OTAs may also update bootloaders, and though slightly less safe than fastboot/ODIN, it is still much safer than having FlashFire flash bootloader partitions directly."
So i suggest to try to flash the firmware directly from odin first

No dice... still doesn't boot up past the red Verizon logo

did you install the firmware in the "AP" box on odin? (after you factory reset your phone)

I did. At this point guess I'm lucky I haven't bricked my phone. Ive tried every possible combination, nothing works!

Redownload the firmware extract it again,factory reset your phone,and try to install the firmware,maybe it's a bad download

Should I be flashing a kernel too? Will it even start/boot without the right kernel?

find out if you phone is refurbished. to install stock ROM you would need the main board and boot to be the same model.
if it's not, then you just need to install bootloader/modem without full ROM. look around in xda for bootloader/modem.

Help recovering data

So I have a friend who decided to mess with his phone, of course without doing a backup, and now he's stuck in a situation that it can't boot even into recovery.
Currently all I see when booting to recovery:
Recovery Booting. . . . .
Set Warranty Bit : recovery
The phone is G900F
He has no idea what version was installed on it before.
I don't need the phone to boot, I need to recover the files on it.
Being a oneplus person myself, I'm not that familiar with samsung phones (my latest samsung was s2).
I've tried to install with odin (3.0.7 - if that matters) the following recoveries:
official twrp 2.8.7
twrp
cwm
All these recoveries showed "Recovery is not seandroid enforcing" message as well as the above when trying to boot into recoveries.
I've tried the official recovery as well:
https://forum.xda-developers.com/galaxy-s5/general/sm-g900f-stock-recovery-5-0-lollipop-t3228871
which removed the "seandroid" message, but that's all.
Not sure what I'm missing.
Any help would be appreciated!

Hmm...
I see that your friend messed up his phone very well .....
Hopefully the eMMC memory is not corrupted becuase then only motherboard replacement would be necessary.
Summarising what you wrote:
1. you flashed "official recovery 2.8.7" -> where did you get it from? 2.8.7 is the very old version!
2. you flashed unofficial TWRP very old (2014) recovery (I checked your link)
3. you flashed unofficial CWM very old (2014) recovery (I checked your link)
4. finally you flashed stock, from old OS 5.0 Lollipop recovery provided from entrusted source - nobody reported that it works in the thread.
I listed this for you in order to underline one thing - READ, READ, READ, ASK, ASK, ASK .... before flashing anything to the phone and tell it to your friend.
Le's start with flashing from ODIN ver 3.12.7 (I am using it) this version of TWRP:
twrp-3.1.1-0-klte.img.tar for G900F which is the latest official recovery:
https://twrp.me/samsung/samsunggalaxys5qualcomm.html
Read how to flash it with odin method (when you open the link).
Edit: Are you sure the phone is SM-G900F? Please check model number on the label under battery (inside the phone).
Edit2: When you enter odin mode check phone model version as well - it is provided by installed bootloader.

Please see attachments:

You can see that it is indeed g900f. I've also checked under the battery.
I've flashed the recovery you asked, however I could not find odin 3.12.7 only 3.12.10, so I've flashed with that (the odin thread on xda does not provide a link for 3.12.7 download).
You can see that it's still not booting with that recovery, it's just stuck at "booting recovery" screen.
I'm thinking perhaps it has a bad bootloader? How would you suggest to proceed?

Ok. Let's continue ... I hope (as I had very similar situation) that the phone is not hardbricked and eMMC memory is not corrupted -> I faced this on my phone and finally had to replace motherboard.
But let's be optimistic:
1. For data recovery - I don't have a silver bullet for this but I found this software: http://www.recover-android-iphone.com/recover-android/how-to-recover-data-bricked-samsung.html
It needs working odin mode so under condition that it supports s5 G900F it should be able to restore some data.
2. For unbricking - I recommend to flash via odin the latest official Samsung stock firmware dedicated to your friend's country/region:
https://www.sammobile.com/firmwares/galaxy-s5/SM-G900F/
You must be registered to download the software. Link for odin 3.12.7 is available on the bottom of the download page.
Just to underline - odin flash most probably (anybody please confirm that) will wipe your data so be aware of that.
Good luck.

Why a full firmware is needed? Perhaps I can flash only the parts required to get into recovery? I count mount the phone from recovery, that's why it's my priority.
I would like to know also if odin will wipe everything if flashing a full firmware?

Because it is commonly recommended way to unbrick a phone.

Perhaps, yes. But:
1. I don't exactly know what restricts your recovery to run properly. Flashing separate recovery failed.
2. You, for example, could try flashing separately one of the latest bootloaders dedicated to G900F from BL section with odin but I doubt it would help.

In my opinion, if odin mode works then bootloader should be OK. But as you wish -
tell me first what stock firmware will you later on trying to flash on your friends phone or in which country the phone will be operated.

Generaly, in my opinion you might try any of the latest bootloaders compatible with SM-G900F phone (here you can find a collection: https://forum.xda-developers.com/showpost.php?p=54094068&postcount=3, I am on G900FXXS1CQI4) but again:
1. I doubt it will help for entering recovery;
2. I still recommend to flash complete stock firmware to unbrick the phone.
However if you anyway decide to try with a bootloader, flash it with odin from BL section (untick auto reboot). Also turn off the phone before and after flashing and pull out battery for about 30 sec. It happens that bootloader doesn't flash properly at once even the odin says "PASS" so some people reported that they needed to repeat flashing a few times. I managed to flash bootloader at first time.

Unfortunateely the phone is not with me anymore, so I won't be able to continue testing. Thank you anyway for trying to help me! I really appreciate your help!
