Why can't I get odin to work after switching boards? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

aHey fellas. So I had my att i545 s4 screen finally break, but I had a backup from cricket first sch r970c. I use straight talk and i just popped in my sim card from cricket into att and it worked. So a couple months later I had the great idea to combine the phones, with the cricket screen. I wanted to know if I could still use straight talk if I put the board from the broken att phone into the cricket s4. And It worked! Skip ahead I forgot the passcode when i upgraded to the s5. Now it is broken and i need my s4 :'( So after resetting, I get the "Firmware has encountered an error when upgrading, and Man, I can NOT get this to work again now. I have used odin for years, and it always fails. Version 3 and a few others version. I have tried everything. Sometimes I get the magisck secure check fail : boot / or recovery / sometimes it says someting about the binary. It will not let me boot into recovery , and i have tried several. tried converthing them from disk to tar. I did the pit files, and the separate pda and boot etc.. nothing will work. Can I please have some help on this one? You guys are the greatest bunch

I'm not sure, but I think the firmware is attached to the board or is specific to the board. This is probably why you're getting an error.

PLEASE HELP!! Samsung Galaxy S4 i337m Fido cannot make phone calls!

Hello, I hope you can help me with my problem.
I am using a Galaxy S4 i337m Canadian Version locked down to Fido. I was trying to install Google Play Edition 4.4.4 from here: http://forum.xda-developers.com/showthread.php?t=2537495. I installed TWRP, did a full wipe, and then flashed the GPE zip. It rebooted, most things seemed to be working, except it showed 'No service', and could not make any calls. It would start to call, then the screen would go black and it would lock up. I went back to a stock rom, but was still getting the same problem.
Now Data is working, and wifi, but cannot make calls. I have checked the APN and all checks out. I flashed the modem.bin file proper for my device via TWRP, I tried via Odin, but it fails in Odin.
I did 2 previous ones for family members, exact same phone, same carrier, with no problems. I don't know why this one is doing this. I have backed up and restored efs with EFS Professional, did not help. Please, please any suggestions.
Thank You.
Edit: I have also left the battery and sim out of the phone for 2 hours to no avail.
Edit: I have tried 5 different 4.4.2 stock roms, all have the same outcome. Cannot make calls, trying to fails and makes the phone lag out. Wifi and data are working, IM sort of works. It says it cannot send, but then 10 mins later the recipient gets it. Still cannot flash modem.bin files in Odin, install goes to the end, then says Fail all in red. I can install successfully the .zip via TWRP though, but it changes nothing. Have tried a few different Canadian modems.
Fixed: Installed stock firmware: I337MVLUFNE1_I337MOYAFNE2_I337MVLUFNE1_HOME.tar, and everything came up as normal. Wiped, flashed Google Play Edition 4.4.4, working flawlessly. Note: Firmware I337MVLUFNC1_I337MOYAFNC1_I337MVLUFNC1_HOME.tar didn't work, even though it was older and only a month apart from the FNE1....your phone likes what it likes I guess. The reason it took so long is it took between 6 to 36 hours to download from some of the 2012-2013 links given at 5-15kbps, I had to just wait and try other things while waiting for the 1.5GB Firmwares to download so I could try them.

No cellular network after installing CM12.1 on Straight Talk SM-G900F (klte)

I recently installed TWRP and then the latest snapshot of CM12.1 for my phone described in title. The android version was upgraded from KitKat (4.4 I believe) to 5.1.1. Everything works fine with the install except I have no network whatsoever. Can't text, can't call, can't use data etc. I made a post on the CM subreddit but didnt get a lot of help (can't post link) . Here is what I have tried: changing APN settings (which I have heard should at least let me call and text if incorrect); flashing various modems such as BOE3, BNL9, and BOD3 (all of them get a FAIL! (auth) in ODIN); restoring my KitKat backup (makes the phone unusable); trying to flash the default L rom for the phone (Also fail to flash in ODIN and TWRP). So at the current time I am basically stuck on CM12.1 and all of its amazingness with no phone functions, I basically have a small tablet at the moment lol.
Here is some information from the about of my phone, if it is helpful at all.
Model: SM-G900F
CM Version: 12.1-20151204-NIGHTLY-ktle (Installed the nightly after the snapshot didn't work, same problem persists)
Android version: 5.1.1
Baseband version: S902LUDU3AOG2
Carrier: Straight Talk
If any more info is needed, just let me know. I appreciate any help, as I am pretty much at square one still. I have googled for days to try to fix this, and haven't come up with anything. It seems no one has had this specific problem before.
If I can't fix this issue, is there any way I can downgrade back to what I had to begin with?

I only have one other sim card on me, and its through verizon. It didn't work on the phone either. I would definitely just buy a new sim card if that would mean it would work. The whole IMEI thing worked, but I am not sure what to do with that information.
(Definitely a G900F? Check what it says in download mode)
Checking the IMEI was to make sure you haven't wiped/corrupted the EFS partition, which contains the Radios needed to make and receive called, along with the IMEI (Hopefully you researched enough to back that up before messing with the phone)
Try flashing another stock ROM with ODIN 3.10.7, go for a different Lollipop ROM from sammobile. com
Some stock ROMs fail to flash, some work, (Phone dependant it seems)
Then boot into recovery and factory reset > try to boot

I have tried 2 separate L roms for the G900F. It says in download mode the phone is a SM-S902L and I read somewhere to get the true model of the phone you look at the FCC id under the battery. Well the FCC id says it is a G900V. at one point in trying to fix it, I tried a stock L rom for the G900V and TWRP told me that it was intended for a kltevzw device and that mine is a klte, so that is why I assume that it is in fact a G900F. I have been using ODIN 3.10.7 to flash everything as well. (Have't tried TWRP for the most recent tries since it takes longer to setup and I doubt it would work but it's worth a try I suppose.
I looked on Sam Mobile for the SM-S902L and there is only one firmware for it, which is 4.4.2, the same one it was installed with when I got it. From my understanding SM-902L is the straight talk branding of the G900V, and trying to flash that firmware didn't work either. Every time I try to flash something it terminates with a FAIL! (auth). What I also understand is that Straight Talk has not released an official version of L for the phone. So it seems my options now are to somehow get the modem to work right in CM12, try to somehow downgrade to 4.4.2, or wait for Straight Talk to release an update for my phone which is not really an option. I just got this phone and I really don't want to have to buy a whole new one just because of software problems. In my mind there HAS to be some way to fix this.
EDIT: my bad, I should have mentioned when I tried to flash the G900V rom it was also CM12, not a stock.
EDIT AGAIN: I seem to have fixed this problem. I have no idea how I did it, but I finally got it to restore to the stock 4.4.2 rom. I seriously have no clue how it worked but it did. Texting and data once again work, but i am now having a problem where I can't make or receive calls. Call immediately ends/goes straight to voicemail. I don't suppose you know anything about that, if you do that would be awesome. I'm gonna call ST in the morning and see if they can tell me anything from their end. But otherwise, I guess my problem is solved. Lol.
I know it sounds simple or may sound stupid but have you tried entering your APN? I have to do that with most of the custom Roms I flash or I won't have service. Also, make sure the correct modem is flashed and up to date.

Bricked AT&T GALAXY S6 EDGE PLUS

I was trying to root my at&t s6 edge+ using Odin. As soon as the process completed, my phone froze on Samsung screen. Then I tried wiping cache and data but nothing worked. I downloaded few stock ROM for Odin but flashing keeps on failing. I read in some thread that new Samsung devices do not support downgrading. I went and checked my current build number and found that to be G928AUCS4CPK1. However, the firmware I was trying to flash were older version.
Has anyone experienced similar issue before? The main problem here is I cannot find the exact build number anywhere. I spent a lot of time searching and finally decided to post here.
Your valuable suggestions will be greatly appreciated.
Thanks.
hey man, you flashed an older version of the firmware? even if it wasnt bricked, your phone is essentially useless now. the efs is gone, meaning you cant make phonecalls or connect to wifi at all. sorry; your phone is bricked. perm.
download mode dosen`t work ?if so the only thing you can try is to use samsung kies to restore your phone but don`t know if that works
I done something similar to my standard S6 Edge the only difference was i was able to start it up ok and i thought everything was ok until i realised i had no reception. I so happened to notice my imei number was gone. I had no back ups of the partition that saved this info so i totally bricked my phone.
I did however find a website that would be able to do a work around ( for a fee of course) for it however it does question your morals as its essentially illegal in alot of countries. I dont want to post anything on here so if you want any info send me a PM.
Exact same thing happened to me... went to AT&T repair center but they didn't have the 'K1' firmware..
anyhow managed to find the latest firmware (gsm-firmware.com)... cost me $4, but the phone is up and running... I only flashed the AP file.. also used Odin 3.12.5..

S7 SM-G930P ~ Boot Loader Issues? SW REV CHECK FAIL : [ABOOT]FUSED 5 > BINARY 4

Hi All.
Thank you for any help you might give me in advance with this issue...
Last week, I tried to root the phone with the SM-G930P CF-Autoroot heroqltespr files with Odin found in this forum. I have rooted a few other phones but am no expert. The root after a few attempts failed (verified a few ways), however, some files must have been affected because the phone "identifies" as heroqltespr. Identifies as when I could plug into my PC heroqltespr would be the name. It was not set this way in the obvious name your device areas. I ended up doing a hard reset to clear the phone and other than the ghost naming everything was working fine.
A day or 2 ago Sprint rolled out a new OTA update which the phone installed. Since then the phone was draining battery life. After uninstalling and reinstalling the SD card today, it seems to have tripped a "Security Notice: Unauthorized Actions". That is when the trouble started. The phone started running hot, basically leaking battery power, and was all lagging. I'm assuming the CPU going Ludicrous speed.
Now, I am in a Samsung Splash screen loop, or or a recovery loop. The only thing it does is go into download mode.
I have tried flashing stock firmware, it fails. I've tried flashing with and without the SD or Sim card. Not really sure what I should be doing. The "P" version of my phone seems to be the bastard child of S7s. Any help you guys cold give me would be great. THANK YOU!
The Download Screen Reads:
Odin Mode (High Speed)
Current Binary: Samsung Official
System Status: Custom
FAP Lock: Off

No it isn't.
I get this error message on the download screen. SW REV CHECK FAIL : [ABOOT]FUSED 5 > BINARY 4
I fixed it.
5 > BINARY 4 error, has to do with a Version 5 bootloader Sprint came out with in 2018. The fact that this is only affected by the SM-G390P further complicates things for the average user. Users on version 5 bootloader will need to wait until/If a version 5 universal bootloader for the SM-G930U to get unbloated firmware. Information on restoring your S7 SM-G930P to where you left off before you started trying to root your phone can be found below. More info on Sprint F'n us and BL Version 5 can be found here
https://www.arencambre.com/blog/2018/01/01/fused-firmware-version-locks-samsung-s7/comment-page-1/. There was a post on XDA (which I can't find) which gave the idea that Sprint came out with this version 5 bootloader to prevent people from flashing the phones to the U version and going overseas with them.
The stock files for the first version of Sprint Version 5 bootloader firmware dated 1-1-18 can be found here:
https://www.sammobile.com/firmwares/galaxy-s7/SM-G930P/SPR/download/G930PVPS5BRA1/206876/
Unzip. Only have auto reboot and Re-partition checked as options in Odin.
If you dont mind me asking, did you ever find a way to root the G930P with the 5th bootloader updates? Is it even possible at this point in time? Im new when it comes to rooting but with the amount of time Ive spent browsing the web it seems as if there is nothing. Thanks.

I got screwed by this, I accidentally installed the P firmware, and now I cannot load U firmware because of this 5 > 4 error. I went to the blog you posted (arencambre), and I am only able to install the U firmware modem (CP package in Odin), everything else has to be P. And because of the P firmware, I am unable to edit APN settings to enable my native Hotspot. Is there anything I can do, besides wait for U firmware to come out with a Version 5 bootloader?

Actually, I am on Sprint, and your directions were awesome, thank you so much! The only thing I had to do was change the line to:

I'm going to put a link to the thread so others can refer to it. https://forum.xda-developers.com/sprint-s7-edge/how-to/hotspot-bypass-nougat-ok-t3563446
Hi all,
EDIT: I posted this in another thread that was about two years old, where I followed the instructions that caused this: https://forum.xda-developers.com/sp...msung-galaxy-s7-sm-g930p-root-xposed-t3503599
That thread seems dead-ish and if you managed to fix this issue maybe you can help me also. Also what was lvpre's original post before he edited it, and would it apply here?
So the worst has happened - got a new (used) phone from Boost Mobile, tried this guide, and now I can only boot to the "An error has occured while updating the device software. Use the Emergency Recovery function in the Smart Switch PC software." screen. Sometimes it does take me to the original "Download mode" screen.
Now, I should be able to resolve this by flashing the original firmware correct? (As in, the firmware that was installed when it came)? Or does it just need to be firmware from the same date range that has the same bootloader? ODIN will still let me attempt flashing on this screen, but I still get the same error when I try again, which on the Download mode screen showed "SW REV CHECK FAIL : [system]Fused 4 > Binary 1"
Any advice here? My S6 bricked when somehow OEM unlock enabled itself and I can't get around the FRP lock, I will be VERY annoyed if the same thing happens with a NEW phone. If I can't fix this I am never buying Samsung again. Any advice on this is very welcome! I emailed Boost to ask them which firmware is installed (because I'm an idiot and didn't write it down but have never had flashing go this wrong before).
EDIT: Booting to recovery just shows a blue "RECOVERY BOOTING...." for a second in the corner and gives a recovery bootloop, just keeps flashing that.
EDIT: I apparently tried to flash an earlier bootloader/etc through ODIN according to the directions in the post I linked above, and after that I now have this problem. Nobody else in the thread seems to have had this problem, and your post is the closest to anything I can find on this issue. I would be in your eternal debt if you could help me out here.
PLEASE HELP!
EDIT: Theoretically if I can find the original firmware it was on I should be fine, right? Everywhere I read if flashing goes wrong you just flash the original stock on it. I guess worst case scenario I download gigs upon gigs of firmwares for Sprint 930P over the last year and find the one that sticks? Or is the fact my recovery is bootlooping and I can only go into download mode mean I'm bricked?
Hello all,
To follow up on my last post, I found success restoring to stock via this firmware:
G930PVPU4BQH1_G930PSPT4BQH1_SPR_7.0.zip
https://www.androidfilehost.com/?fid=817550096634799807
I left my original post just in case anyone messes this up the way I did. I still need root, but now I know how to reset to stock in the event this happens again.
For the record I bought a used Samsung Galaxy S7 off the Boost website.
IF YOU FOLLOW THIS GUIDE, OR ANY, MAKE SURE TO GO INTO "SETTINGS -> ABOUT PHONE" AND MARK DOWN WHAT FIRMWARE THE PHONE IS CURRENTLY ON AS STOCK. THIS WILL SAVE YOU A HEADACHE TRYING TO FIGURE OUT WHICH FIRMWARE YOU NEED TO DOWNLOAD IF THINGS GO WRONG. DO NOT PAY FOR A FIRMWARE DOWNLOAD OR USE FILESHARE SITES, GO HERE: https://simunlockremote.com/galaxy-s-series-firmware/ AND FIND THE VERSION YOU ARE ON AND IT WILL DIRECT YOU TO A FAST GOOGLE DRIVE LINK.
Thanks to all the hard work all the devs have done that have gotten use. I still need root soooooooooo if anyone knows how to do that let me know!
CHEERS! I am so happy right now

I've got a Galaxy S7 G930P from Sprint. I just switched to T-Mobile a couple months ago and brought my S7 phone with me. I was hoping to flash my rom to either the G930U or the G930T (T-Mobile) version, but both are still bootloader v4 and I hit the same error that everyone else on this thread was hitting.
My main problem is that my S7 phone can't send/receive MMS messages on T-Mobile, even after updating the APN settings, and, even worse for me personally - my phone gets below average reception everywhere I go, presumably because my Sprint G930P rom has locked down some of the bands that T-Mobile uses.
Aside from getting a new phone, do I have any options? Or am I stuck waiting for either a G930T or a G930U update based on bootloader 5?

If your phone is uicc [sim] unlocked from sprint... you can try the following.
1. Odin a dec/Jan firmware...like QJ3. But replace the cp slot with the file from the latest u firmware. This is the modem file.
2. When your phone starts, you will receive a pop up message, just hit cancel.
3. Install a package disabler like sabs, bk, adhell2. Disable securitylogagent . This should remove the annoying message. Sabs takes a little effort to setup, but you may need it for the disabler part. Restart after disabling.
4. Pop in sim. See if the additional bands are unlocked.
If you fail, you can always just odin back to a v5 sprint firmware. But don't try it unless you are stuck on the current firmware and your phone is doing nothing. It won't brick your phone.
While the firmware is not downloadable, modem files can downgrade one major update.
This worked for me, but I only have sprint and haven't tried it elsewhere.

Going CRAZY trying to restore S7 to factory

I wiped my girlfriend's S7 for Sprint (SM-G930P), in order to run tools to try and recover deleted internal saved voicemails. (Which I never could find). She wanted it unrooted. Can't remember what I did, but now the phone won't boot. I think the recovery is screwed up.
I had originally started with this post....
https://forum.xda-developers.com/sprint-galaxy-s7/how-to/root-firmware-qg1-tweaks-mods-t3654700
At the command line, ADB does NOT see the phone.
I tried calling 10 different numbers for Samsung, no one could help me.
Kies and/or Smartswitch Emergency Recovery requires the serial number, which I do NOT have.
Everything for rooting went well, but now when unrooting, I get the "unauthorized software, please contact service provider screen" or 'sometimes' I am able to get to the bootloader screen.
I don't know which version of Odin, which firmware, whether it should be separate AP, BL, etc, or a single file.... Rooting never used to be this difficult before locked bootloaders. I'm literally pulling my hair out because now I need to spend $250 to go buy my GF another Sprint S7.
I've tried this post also, with NO luck....

ODIN = FAIL on everything. Although Odin does recognize the phone. Please help.

So Odin does recognize the phone in download mode? Then you should be able to restore it. Are you using the special version of ODIN for the S7? When you boot in download mode, read the firmware version 5 characters back from the end. Does it say 4 or 5? I would completely reflash the firmware. The latest firmware will probably do the trick, but it will update the binary for the bootloader, but it is better than buying a new phone.
