Newest bootloader & modem

I want to flash the latest bootloader and modem to my G920F. But the problem is, that I have no idea for what is this etc. Could someone explain, could I install the bootloader and a modem with a different designation than my rom? For example, I have now COI9, can i flash another modem than with the designation COI9? I someone could, please link to the latest version, thank you!

You dont need to do it... Always stick with the modem and bootloader same as the system... Mixmatching those files can couse battery drain ( radio interference , deep sleep problems ) ... For the time ive used the s6 COI9 was the best modem i ever tested.. So stay with OI9

yes and no ... as i said mixing ap,bl,cp can cause weird stuff ... for my opinion is IO9 BTU ... best battery life and less bloatware ... and i think will be the 1st to get MM official ...

so, I searched at the forum and probably i'll test the marshmallow, then I'll try a few combinations with roms, kernels etc. because my battery life on my s6 dont satisfied me

If you try MM make sure your device will "deep sleep"

Hi,
I have this galaxy s6 that only boots in download mode.. I literally flashed every stockrom and recovery etc. Have you got any other solution I could try? I tried pit file but it gives me an error... maybe it's not the right pit file. PLS ow pretty PLS, give me a link to a good debloated odin flashable stock rom and a good pit file. I'm pretty desperate about this phone. it does boot in download so I guess this phone is still fixable. I also tried Nand Erase All option, it passes but still no normal boot nor recovery. so can you tell me where to find a good rom and pit file?
Thanks in advance

I've been there with my S6 Edge...only a week ago while I was installing LineageOS. I was feeling pretty hopeless for awhile but installing a custom ROM got my phone to the point where it was usable again. I'm still burning through firmware variations from sammobile in search of a better modem but at least I got it working again. Odin is your friend.

Can I make any rom zip flashable in odin? Because I can't get in recovery... And I don't know if I'm rooted.. Because I did flash cf root but yeah... I don't know if I'm rooted now.

Why can't you get into recovery? If you can get your phone into download mode, then you can use Odin to install TWRP which will give you access to recovery. You said you had the S6 right, not Edge? You can get TWRP for that version here https://twrp.me/samsung/samsunggalaxys6.html and then install it with Odin. After that, boot into recovery, and then plug your phone into a computer and transfer your ROM onto the phone and install it. If you aren't able to get that part of it done, then the stock firmware for your S6 may be available for download from https://www.sammobile.com/ and those can be flashed using Odin. If one of those doesn't work, try a different one until you find one that works. Good luck; don't lose hope. I have found my S6 Edge resilient and hard to permanently brick.

I thought I was done for last week when I flashed a package from Sammobile that my phone didn't like and it resulted in Error message from Odin. After that, download mode showed up as wrecked and said to use Smartswitch to enter emergency recovery mode. I tried a few versions of Smartswitch but they all kept saying my device was unsupported. I went to sleep feeling pretty lousy.
The next day I started fresh and had a few more packages from Sammobile to try. Even with the message about "emergency recovery mode", I was able to install a new Sammobile package using Odin. That replaced modem, system, bootloader, everything the phone needed. Except the phone was stuck in a bootloop and kept restarting every time it go to the "installing android" part of the boot process. At that point I shut the phone down and installed the latest TWRP recovery, booted into recovery, and transferred my ROMs + GApps onto it and then installed them following the ROM's installation instructions. It was pretty hairy for awhile but my persistence paid off and now it works again. Hopefully you get yours working.
What do you mean "nothing wakes up this phone" does it hang at a particular part?

I don't think you can. You need to install TWRP recovery in download mode before you can flash ROMs. Is that what you're having problems with?

Thanks for sticking up with me. We'll, the phone only boots in download mode. I flashed literally everything... From custom recoveries to stock roms, also had the smarts witch notification but smarts switch nor Kies doesn't fix the problem. I tried flashing recoveries, different versions, nothing. What I mean with waking up the phone... Well even after a successful Odin stock firmware flash, the phone doesn't boot by itself. Tried with the auto reboot ticked off but... Yeah... The phone only boots in download mode. But in download mode I see that it says CUSTOM BINARY,.... so... It flashes but... It's not booting. Not even getting a starting up screen that freezes... Nothing...all black... Only download mode. I just now tried converting a custom Rom zip to a tar file... Flashed it... Failed... Blablabla... This s6 is giving me a hard time! now, it' s a phone from a college that actually threw the phone in the garbage... But I retrieved it and I wanted to fix this s6. It's a good phone... It goes in download mode so.... That thought keeps me hopeful!
Again thanks for the support...

okay so, tried a couple more firmwares...they all pass in odin but not booting my phone. also not in recovery. tried flashing twrp and stuff but can't get it to boot! It doesn't hang on a screen. it just doesn't boot. only on download mode I get it to boot. Could this be a hardware problem?? I think not because it boots in download mode. Maybe try to flash bootloaders? Are there other recoveries? CWM, Philz touch?

Cannot flash Stock Recovery.img after attempt to root phone failed

Hello,
I have a Galaxy S6 Edge SM-G925W8 on firmware 5.1.1. I recently updated my firmware using Smart Switch which brought me to 5.1.1 and wiped out my root access. I attempted to re-root the phone using the same TWRP Recovery I used to root it previously, which flashed successfully according to Odin. I was however unable to enter TWRP Recovery, getting the error "recovery is not seandroid enforcing" while at the booting screen. I figured maybe the TWRP Recovery I flashed was outdated and no longer worked for firmware 5.1.1 so I am now attempting to flash the Stock Recovery.img to wipe out my now broken Recovery. The problem is when I flash the stock recovery, Odin claimed the flash failed, giving no reason as to why. I'm not sure what I should do now - return to stock recovery (which fails when I attempt) or is there perhaps a way to restore TWRP Recovery and access root privileges once again.
Thank you for your help!

"recovery is not seandroid enforcing" is not a error, it's just a warning. If it stuck at this screen, that means the TWRP you're using is not compaitable with installed bootloader.
What's your PDA number?

I'm sorry I'm not sure what that number is. I have searched through my phone's "About Phone" and "Developer Options" but did not find anything called a PDA number. If you mean the file I used to flash the TWRP Recovery, its name is "twrp-2.8.6.0v2-zeroltetmo.tar". If that's not what you need, could you please tell me how to find it?
Thank you!

Type *#1234# on dialer. It'll show you software version (AP), modem -baseband- version (CP) and CSC version. I'm asking for AP version.
The TWRP version that you're trying to use is pretty old. The latest official TWRP is working on latest Android 5.1.1 bootlader. Try this; (for T-Mobile variant)
https://dl.twrp.me/zeroltetmo/twrp-3.0.2-0-zeroltetmo.img.tar

Thank you for getting back to me, will that T-Mobile version work on my Canadian Sm-G925W8? It's with Rogers, not sure if that makes a difference.

Thank you for the link, I just finished flashing that TWRP Recovery and it appears to have worked. The problem now is I booted into the Recovery, installed SuperSU2.49 to add the SuperUser permissions and now I'm stuck on an infinite boot loop. The phone doesn't make it past the boot screen. Is there a way to reverse or fix this? I am still able to boot into the TWRP Recovery however, anything I can do here to fix the problem?

You flashed a whole old version of SuperSU. You need to flash latest beta;
http://download.chainfire.eu/932/SuperSU/BETA-SuperSU-v2.71-20160331103524.zip
But, you have to do it after reflash the stock firmware, because you modified the /system, which you shouldn't.
Or, just wipe everything and flash a custom ROM (I prefer this ROM )

Thank you so much for the advice. I ended up downloading the stock firmware 5.1.1 for my phone model (AP number matched and everything) although what I didn't expect was for it to delete all my data and storage. I had no backup...as I didn't expect the root to go bad. But since it happened anyway, could you tell me a bit about these custom ROMS? The reason I never wanted to use one was due to not wanting to lose my data. But it happened anyway...so I might as well see what it's all about. I checked out the link to the one you said you prefer, is it overly beneficial to use a custom ROM? Does it already come Rooted or do I still have to do that myself?
Please let me know!

[Q] SM-G900F Baseband Unknown / IMEI Null / No Signal (For experienced users only)

Hello Guys,
I need serious superuser help.
Trying to flash a custom ROM, screwed up my IMEI and baseband.
Now I get a null IMEI and a Baseband Unknown on the phone's info.
I reflashed to 6.0.1 stock using the methodology of this thread here:
http://forum.xda-developers.com/galaxy-s6/development/g920f-android-marshmallow-6-0-1-beta-t3293941
I also flashed a few different custom ROMs without any success.
I rooted and installed Wanam Xposed and IMEI Changer, (Using this link: http://forum.xda-developers.com/galaxy-s6/development/mod-wanamlite-1-0-t3095155) but even if the IMEI is showing right this time, the baseband still shows as "unknown" and the phone won't get any signal.
Before flashing the ROM for the first time, I kept a backup of the EFS. I restored it with TWRP but still no love....
I have read countless threads over google but I haven't manged to solve it.
Can someone help?

Did you back up EFS with TWRP? Some other tool?

Yes, TWRP I have the efs.emmc.win and md5 file.
I tried to restore with TWRP but still no love. .

Guys ,anyone? At this point I am really prepared to try anything

Last thing I tried is getting a full Nandroid backup from a fully working G920F and restored onto my own phone.
Still no love. Factory reset, wiped cache and data from TWRP but still no love.
What could be the issue then???

have you tried smart switch ??

It gives me an error when I am trying to setup the device initialisation:
"Unable to find the serial number,model name or IMEI on the Server. Please check and try again"

Have you tried using ODIN to install the latest stock image? That did the trick for my old S5 that had an IMEI issue. I highly recommend using the SamFirm tool from this site to download stock images directly from Samsung.

I used SamFirm and downloaded three different stock roms for the UK and one for the nordic countries. They all pass from Odin but the phone does not boot. I get
"DM-verity verification failed" and
Need to check DRK first" and the phone won't boot up ....
Is this error because I am trying to install a wrong CSC ROM ? Or an incompatible ROM ? I can't figure it out.

I believe the dm-verity error means you've got the wrong ROM. You need to download the firmware for the device/region your phone is.

I know how to fix it

The way of fixing DRK that I know is via box (Octoplus, Z3X, etc.), but often IMEI gets reseted in the process (at least it was in my case).
If DRK is damaged, phone won`t boot without a custom kernel (which trips knox on Android versions 5.1.1 and above), if DRK is fixed, phone can boot with stock kernel.
In SmartSwich I suppose you used IMEI from back of the phone without / right? And for model you used SM-G920F (or whatever model you have) in capital letters?

Stuck in a ****tier place than what I started.
Last thing I tried before my phone died was trying to install the latest Stock marshmallow ROM for my device. The one I downloaded via SamFirm passed Oding but never booted.
Since then, I have tried to flash 12 other ROMS with different CSCs (yes 12) from BTU (which my phone is supposed to be) to VIR , to O2U to TEN. Nothing worked!
I had kept a nandroid backup of a ROM that was working (5.1.1 without IMEI or baseband) and even that does not boot now either.

This sounds logical. Do you have a box? Where did you fix your DRK? And I don't think I really care about the IMEI at this stage, right?

Well, not necessarily I think... In one of my previous tries, I managed to install stock O2U_G920FXXU3COI9_G920FTEF2COH1 (but first I deleted the "hidden" partition from the tar). Was that a coincidence you think ? #not_sarcastic

That's right. Shouldn't I ? I can't reset the phone for the life of me!

Did you do a factory reset in recovery, immediately after flashing the correct stock ROM in Odin, and before booting into the ROM? Uncheck auto reboot in Odin, when flashing is done, power & vol- to turn phone off, then boot into recovery.
Sometimes it's the simplest things that help.

I did exactly what you described. Only issue is that as soon as the phone boots, it won't let me enter recovery immediately. Before entering, I see the Green/blueish Android screen trying to install something. It stops at about 33% and it says "erasing" and only then can I enter recovery. To which point, I can erase the cache and wipe data but the phone won't boot onto the System. It just hangs there.

Not erase cache & data, factory reset.

I can't boot into the system to factory reset because I am stuck in the Samsung boot loop. Wiping data and cache from recovery is the same thing... or is there something I am missing here?

Factory reset from recovery.
Have you tried booting into safe mode?

Phone boots but recovery mode does not work (after flashing TWRP)

Hi all, using S7 SM-G930F. Just got it yesterday and first thing I wanted to do was flash TWRP so I could put the new Pixel OS onto it.
Used ODIN, got the pass message as usual... phone rebooted automatically into stock OS. I turned it off and tried booting into recovery mode but it gets stuck at the splash screen. Nothing happens, not even stock recovery. I re-flashed TWRP without auto-reboot option this time but the same thing happens.
So essentially I have a phone that works but no recovery mode at all I can't find anyone else with this same problem, please help. I can't get any further without it. Ideally I want to avoid flashing the entire stock image. Thanks

OEM unlocked?

Do you mean flash the entire stock firmware or just stock recovery? I'm attempting to extract stock recovery from firmware now... but if I have to flash the whole firmware then I guess I have to.

Just flash full stock, you won't lose anything unless you flash CSC which resets the phone after the flash
But you do know you have to wipe your phone to get TWRP installed correctly right?

Nope. I didn't know. No guide I used ever states that anywhere (I'm a CWM person also, first time using TWRP).
Sounds strange to me.. How do you root your phone using TWRP then if you have to wipe it first?
Can I even use CWM for S7? Didn't think so as there are no guides for it.
Not worried about losing anything as only got the phone yesterday but really worried about the stock firmware flash not working the same way TWRP doesn't, that's why I wanted to avoid it if possible, I'll give it a go. Thanks

You don't have to use TWRP to root, if you're not bothered about having custom recovery you can just flash CF-Auto Root using ODIN, that will root without the need for TWRP
Reason you have to wipe with TWRP is because of encryption the phone is using - reading the TWRP thread would be a good plan before blindly flashing stuff
Don't worry about flashing stock, I have the same G930F, flashed stock a couple times using ODIN, no issues

Id flash stock again to fix recovery, then try TWRP with ODIN 3.12.3

I followed http://galaxys7root.com/galaxy-s7-s7-edge-root/how-to-root-galaxy-s7-s7-edge/3/
They never mentioned anything.
I just flashed stock firmware and now I can't do anything, no recovery, no download, no OS. Bootloop no matter what...
http://stockroms.net/file/GalaxyS7/6.0.1/SM-G930F/UnitedKingdom
This is what I used...

Kept trying and eventually got back into download mode (it was really hard)...
I am still lost on what to do now though.

Follow XDA guides, not random sites
OK, considering the phone is pretty much empty and new, just flash all 4 ROM parts with ODIN
AP, BL, CP and CSC, factory reset the phone and start again from scratch
This time read the TWRP thread, or the CF Auto root thread here on XDA before doing anything at all

Thanks! Boots now. Shame I only really found this place's guides after the one I used failed, starting again now

Did you unlock your bootloader? That is way flashing twrp works but would not boot twrp

I know the problem. Make sure "reboot automatically" is DISABLED in Odin when flashing TWRP. If you do not it will fail. I know from experience. Im assuming you already know to habe OEM unlocked etc etc

Need help with Odin, cannot return to stock :(

Hi,
Using latest Odin I am trying to return to my phone to stock but cannot 
I have tried 4 different firmware’s already (over 20 times) and each one will PASS the flash process, phone rests, installing system update (stops at around 30%) and during the blue screen the update stops, resets, receive Erasing message for a bit and then NO COMMAND and phone will simply not boot. (with some flashes the stock recovery is not even available, working or present)
... only way to boot the phone is to install TWRP... installing the NO VERITY file seems to help in booting…
I have noticed when i plug the phone is it comes up as another device name (from a previous ROM) so i am guessing it hasn't been wiped correctly (i did formats, factory resets, wipes many many times and no change)
Back in DOWLOAD MODE under system status = CUSTOM (after flashing stock firmware)
My guess is that the new firmware I flash simply wont stick, or is half installed, or could be something to do with encryptions,
Some of the logs I see include:
Failed to open recovery
Reboot recovery cause UNKNOWN
E: Failed setting up dirty target
Fail to mount /system as rw
i have no idea what else to try

You flashed the wrong firmware and corrupted your device.
You should flash the newest available firmware for your specific model number. You might have to flash the PIT file for your model number along with the firmware with the "re-partition" option checked in Odin when you flash it.

I need to keep v3 bootloader, i am very sure that latest firmware will work but i am trying to avoid it, and i never flashed the wrong firmware, i have tried aroud 6 different v3 and none will stick, can you suggest where i can find the PIT files and possible guide? without the pit file the repartition option fails each time...

If you didn't flash the firmware then how did it show up as a different device "from a previous ROM", as you said?
They might have been V3 firmware, but was it for the same model number of V3 as yours? Are the model numbers different? Is V3 the model number? Or is it the device branded name?

Thanks for the feedback, several months ago i flashed G935FXXS3ERHD_G935FXEO3ERG2_XEO on the S7 Edge International, so firmware is correct, i flashed a custom ROM - Glamour ROM a S9+ Ported ROM for the S7E, everything worked fine until i tried to revert back to stock, every other V3 firmware apart from the one mentioned above wont flash correctly, either fails or boot loops, has no stock recovery, and system status is still showing CUSTOM, when i plug the device in it will come up as Galaxy S9+ ... for some reason i cannot do a proper flash on it,
I am almost certain i can do a proper flash with the latest firmware but i am trying to avoid that...

Have you tried factory resetting the device then try flashing via Odin? Sometimes there is conflicting data that prevents from flashing the firmware.
You might not have a choice of which firmware to flash to repair your device.

more than you can imagine, every possible wipe and combination has been done with no luck at all

Well then, suck it up and flash the newest firmware, you are out of options.
Your device probably doesn't allow downgrading, in this case, you can only flash exactly what was on the device before you caused the issue or a newer firmware, you can't go backwards to an older firmware.
If you're trying to flash an older firmware in an effort to get past a locked bootloader, you are probably wasting your time, that doesn't work out most of the time.

That definitely makes sense that i cannot downgrade but i am flashing either the same firmware or slightly newer staying on the same bootloader version.
