Test Device and aboot -2??? - AT&T Samsung Galaxy S7 Edge Questions & Answers

Ok so the phone i have is/was actually a G935T, and had G935T firmware (BRC1) even though it says G935A on the board inside the phone. I tried to flash a different firmware, foolishly without turning off FRP, or turning on OEM, yeah im dumb. I ended up being stuck with the SBL error upload mode and couldnt even get back to download mode no matter how many times i tried, eventually i learned about EDL mode and took the phone apart and shorted the TP and re programmed the phone etc. and got it back to download mode.
Everything i flashed would always be successful in Odin, however nothing would ever boot past the looping S7 edge boot screen and recovery on every single firmware would also loop and ultimately give me kernel panic errors. i began to suspect that maybe i left something unplugged inside so i took it apart again and tried to keep the heat shield pressed down a bit more (since i had to open it up to access the test point) as i assembled the phone back together. No more kernel panics, but the boot looping was still present. I have tried G935T, A, P, V and U firmware and all of them do the same thing. Ive used the proper PIT files.
To make things worse, i flashed Oreo without realizing that i was putting my bootloader in handcuffs. To make things even MORE worse, i used a tool which claimed to convert an odin archive to be ADB enabled. now my device boots and says S7 edge etc, but then immediately goes to SBL error upload mode. Recovery still loops. Whats interesting though, is that since i used the converted archive, my device says exactly this in download mode:
ODIN MODE (HIGH SPEED)
PRODUCT NAME: SM-G935A
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Custom
FRP LOCK: ON
WARRANTY VOID: 0xffffffff (0x0)
QUALCOMM SECUREBOOT: ENABLE fffffffe

Any help would be much appreciated. Its going on nearly a month now trying to get this thing to work. I dont care about warranty, i dont care about knox i just want my phone to work....i cannot find any information about test device, how to go back to system status official or how to properly reformat all partitions that effect FRP or whatever the hell is locking me out of it. Also i am now not even able to flash ANY firmware because it keeps failing saying something about aboot fused -2 and none of the firmware i have will successfully flash. Im stumped.

I called a repair shop today and they want to charge me $30.00 to flash it with what they have. That seems a bit high to be honest. Should only take about 10 minutes right?

Fuse -2 happened to my T380 Tab A tablet when I flashed wrong aboot and boot in the same TAR package.
So steps to fix it:
find the right combination firmware;
unzip it with 7zip archiver;
download TAR_MD5_PACKAGER;
open folder with unzipped comb_firmware and delete all files below from it:
-aboot,
-apdp,
-boot,
-devcfg,
-msadp,
-rpm,
-sbl1,
-tz.
copy all files what left to TAR_MD5_PACKAGER\parts;
start TAR_MD5_PACKAGER and press 1 to make tar file;
flash this file with Odin as AP;
now the fuse should switch to 1;
next flash the full combination file or stock firmware.
FUSE Number stands for software version,
samsung has protection against downgrading software,
So once you flashed firmware with number 2 in it, the device will change the fuse to 2 and after that
you will not able to flash anything less than with number 2 and so on.

S7 edge up and running
Dude thanks a lot!!! I read through multiple threads. Some more technical than others but this one was plain simple and it worked. Some of the files I deleted were a bit different, but hey, it got bit to work. One other thing for anyone experiencing the same issue, just look for a combination file matching your phones actual bootloader. Once you find it, just start deleting the files Odin is indicating are not letting the flash complete. In my case, files: hyp.mbn, pmic.elf, emmc_appsboot.mbn, xbl.elf. once I deleted those files I was golden. :laugh::laugh::laugh:

Samsung Galaxy S5 SM-G900F/SM-G901F continuously restarts

Hi all members of xda, sorry for my bad english, i will try to explain what exactly is happening with my phone.
I power it on, it`s vibrating and appear "Samsung Galaxy S5........POWERED by android", and that`s all, it continuously restarts itself until i remove the battery.
I can`t enter in recovery mode, it`s restarting from there continuously too... In download mode i can enter, and there at PRODUCT NAME it says is SM-G901F, but under the battery is SM-G900F.
In download Mode this is all what it says: "ODIN MODE (HIGH SPEED)
Product Name: SM-G901F
Current Binary: Samsung Official
System status: Custom
REACTIVATION LOCK: OFF
Knox Warranty Void: 0x0
Qualcomm Secureboot: ENABLE (CSB)
RP SWREV: S1, T1, R1, A1, P1
Secure Download: ENABLE
UDC START"
This is all.
So, i think that boy from who i bought the phone tryed to root it or flash it with another rom?
Can anyone help me please? Thank you.
What it says the model number is when in download mode is what needs to be believed. There seems to be a lot of this lately.....devices being marketed/sold as the more popular 900F variant when they are not.
You have to get the correct firmware from sammobile or samsung-updates and flash it with odin. I doubt it's the person who sold it to you as apparently nothing can change the info in download mode, and the sticker says something else. The seller may have tried to flash a 900F firmware, but that is probably all he's guilty of......

Thank you @keithross39, i flashed it but for the first time when he booted up, he passed the "Samsung Galaxy S5....Powered by android" screen, appeared T-Mobile and then he restarts again...and it don`t work yet....keeps restarting itself...
I have and printscreen with odin when it passed but i can`t put it, after 10 posts only.
So what can i do next? Any ideas? Some roms? Thanks.
Try accessing recovery now you have flashed (Vol up, home and power keys together) and wiping cache and/or wiping data/factory resetting.
http://i.imgur.com/rVnFwJM.jpg
@keithross39, appears in left up corner Recovery booting... but its restarting, doesn`t enter in recovery menu...
Can you tell me which version of Android you flashed?......
http://i.imgur.com/rVnFwJM.jpg
This one DTM-G901FXXU1BPA2-20160125170733 @keithross39
5.0.2 from Germany (T-Mobile).
Try flashing this........

It IS for the 901F, but it's what the hosting website calls a 'repair' firmware.
So it is supplied as separate files that have to be loaded into their corresponding 'slots' within Odin. I'm guessing it will be unbranded too. But being a repair firmware, it stands a better chance of successfully flashing and booting than a normal firmware.
http://i.imgur.com/rVnFwJM.jpg
Just finished to flash it and still keeps restarting, didn`t worked @keithross39
What about recovery now, can you access it and do the wipes?
http://i.imgur.com/rVnFwJM.jpg
No, keeps restarting... What if the owner accidently flashed rom for G901F but the phone model is G900F? It can be?
Download mode says 901F.....
AFAIK the info in download mode is hardcoded into the device and can't be changed.....
I can't see how it'd be any other variant....
http://i.imgur.com/rVnFwJM.jpg
Ok, so what i can do more? With box maybe it can be done? Or you don`t know @keithross39? I am very greatful for your time.
So far, everything you've tried would have put your device back to stock and wouldn't have affected knox.....
Knox is regularly used by Samsung to assess whether your device receives a warranty repair. As long as knox remains at 0x0 (as seen in download mode) your warranty is intact.....
Going custom is your only other option and that will trip knox and void your warranty. I can suggest how you can go custom, but it's up to you whether you want to torpedo your warranty when the ability to flash your device successfully is in question.
http://i.imgur.com/rVnFwJM.jpg
@keithross39 the warranty expired. If you say that custom rom will make it work, i say let`s try it...
Don't get me wrong fella....I'm not saying this WILL work.....
There is an element of risk whenever you attempt to modify a device. As I said, I can provide you the information that *should* set you along the correct path, but at the end of the day there are never any guarantees, and it's down to you whether you want to take the risk or not
http://i.imgur.com/rVnFwJM.jpg
Ok, i understand mate, i will take the risk, anyway what can go more wrong...
Lol....don't even *think* that sort of question, let alone type it on a public forum......
Ok....here goes, but first, the usual disclaimer....
"This information is provided for information only. Neither I, nor anybody else on XDA is liable if you choose to undertake the processes set out below. By choosing to complete the steps below, YOU are assuming responsibility for the working (or otherwise) condition of the device when the processes have been completed"......
Having said that, members of XDA will always voluntarily try to help you recover your device if things go wrong.
Get your TWRP from here.....
http://forum.xda-developers.com/galaxy-s5/development/recovery-team-win-recovery-project-t3110930
Get your SuperSU from here.....
https://download.chainfire.eu/696/supersu/
Follow these instructions.....
1) deactivate 'Reactivation Lock' (can be found under Security in Settings).
2) copy SuperSU zip to your device/external memory card.
3) boot into download mode.
4) Odin flash TWRP.
5) DO NOT allow phone to boot, (uncheck auto reboot in odin and if necessary remove the battery as soon as the TWRP flash has completed) then.....
6) boot directly into recovery. (Vol +, Power & Home button combination)
7) flash SuperSU zip.
You now have root and can flash your choice of custom rom for your device.

@keithross39, how can i make step 1? And i don`t know how to make step 2 neither... :-/
Step 1 can be (at least) checked by booting into download mode and reading the info on the screen. In your first post, your info showed that reactivation lock was off.....hopefully that hasn't changed.
Step 2 requires a micro SD card. You copy the SuperSU zip to that and put it into the phone.

SM-N910F FW problem

Hello everyone!
I need a little advice to fix my softbricked note 4
So here are the facts:
I boght a bricked N910F i tryed different roms from sammobile using odin and twre, more than 7 to be specific, and most of them did t work as it shoul. My imei was the same as on the case but i noticed SN was different in system and knox 0x1.... I got a version of android 6.0.1 to work but there were different little, big problems like not rememering wi fi passwords, fingerprint not working version :null in testing, and often restarts and bootloops after installing different aplications. i tryed many things even repartition with proper pit file, i still had back-up of my efs but considering the serial number was screwed up i gave up trying anything else. I tryed rooting with different methods but everything failed.
I boght another N910F with screen broken but working mainboard and knox 0x0
Swaped the mainboard, tryed samsung kies 1, entered serial and model and it gave me the fw i needed to flash. Tryed flashing with kies and at the middle of transfer it said failed and phone froze, didnt even power on for a while. Tryed again after a few howrs, same rezult with message emmc read fail, and at the bottom emmc write fail.
kies said i need PDAG2/CSCE2 / PHONEE3 CNX
Now, later in the evening i managed to power it on agan and i dont know what to try so i dont screw up with knox
Here are some pictures of my current status:
Current status: cant post picture...
ODIN MODE (HIGH SPEED)
PRODUCT NAME SM-N910F
CURRENT BINARY Samsung Official
System Status Official
REACTIVATION LOCK OFF
Knox 0x0
qualcomm secureboot enable csb
RP SWREV S1 T1 R1 A1 P1
secure download enable
UDC STAR
"Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again"
What should i try next?
Thanks
Later Edit:
looked up on youtube and found that smart switch can do the work, tryed it and seems it went all the way and installed proper rom without fail. LOL
Morning edit:
So everything worked perfect last night so i left it on fastcharger. In the morning i found it in download mode with dii emmc read fail, could not do normal boot.... After this i have to let it rest a bit without battery, then it boots up ok, works a few minutes then it shuts down and never wake up

I found the only way to keep it working is by preventing it to go into sleep mode. Play music on repeat muted keeps it working
Lucky i have fast chargers and 3 battery
i tried different keep alive apps but they eventually fail and phone dies

S7 EDGE - Device Storage Corrupt (RESET DEVICE not working)

Hi there. I tried to fix this by myself, but I'm out of ideas.
So basically, my brother had this S7 Edge working fine, but one day he just got the message from the title, and he can't hit the RESET DEVICE button. Touch works, Volume button works and Power ON/ OFF. I even plugged a mouse with OTG cable, tried to click the button but nothing.
Then I went into recovery mode, tried to wipe/ erase data, and fails with this message:
_E: format_volume> make ext4 failed on /dev/block/platform/155a0000.ufs/by-name/USERDATA with 1 (I/O error)_
_Data wipe failed._
Then I've tried to use ODIN (v3.12) to flash the latest stock ROM for UK, loaded BL, AP, CP and CSC, marked AutoReboot and F. ResetTime. All works fine, it ends with wiping the data and fails with just ERROR on the screen. If I boot the device, I get the same error as in the title screen.
I've even tried to mark NandErase/ PhoneBootloader Update on ODIN, and nothing.
Phone is original, never been rooted nor unlocked. Never been dropped nor physically damaged This is the info I get from DownloadMode:
ODIN MODE
DOWNLOAD SPEED> FAST
PRODUCT NAME: SM-G935F
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Custom
FRP LOCK: OFF
Secure Download: Enabled
WARRANTY VOID> 0 (0X0000)
RP SWREV: B:1 K:0 S:0
Is there ANY way I could fix it? I don't care about the data inside, I just want to fix the phone for my brother, as he's only been using it for 2 weeks. It's second hand, so no warranty...
If you guys know or have any ideas, I'm open to anything. I just don't want to end up switching the motherboard, because the point is to fix it without any other costs.
Thanks in advance!

I DONT KNOW which direction to go

Ok so the phone i have is/was actually a G935T, and had G935T firmware (BRC1) even though it says G935A on the board inside the phone. I tried to flash a different firmware, foolishly without turning off FRP, or turning on OEM, yeah im dumb. I ended up being stuck with the SBL error upload mode and couldnt even get back to download mode no matter how many times i tried, eventually i learned about EDL mode and took the phone apart and shorted the TP and re programmed the phone etc. and got it back to download mode.
Everything i flashed would always be successful in Odin, however nothing would ever boot past the looping S7 edge boot screen and recovery on every single firmware would also loop and ultimately give me kernel panic errors. i began to suspect that maybe i left something unplugged inside so i took it apart again and tried to keep the heat shield pressed down a bit more (since i had to open it up to access the test point) as i assembled the phone back together. No more kernel panics, but the boot looping was still present. I have tried G935T, A, P, V and U firmware and all of them do the same thing. Ive used the proper PIT files.
To make things worse, i flashed Oreo without realizing that i was putting my bootloader in handcuffs. To make things even MORE worse, i used a tool which claimed to convert an odin archive to be ADB enabled. now my device boots and says S7 edge etc, but then immediately goes to SBL error upload mode.

Stock SM-T580 Bricked, can't restore stock image

Hello, I tried to use my unrooted, stock Samsung Tab A (SM-T580) and discovered the battery was completely dead. After leaving it on charge, I tried to start it and it would only sit at the Samsung logo. I have tried a soft reboot, hard reboot, pulling the battery, etc. I cannot enter recovery mode, but I can enter download mode. As a precaution, I installed a new battery, but this did not fix the problem. After this, I tried the following while in download mode since it was the only time USB is recognized by my PC:
Samsung Smart Switch
Using the emergency recovery option it says my device cannot be updated
Odin3 v3.12
Using the latest image from SamMobile for the SM-T580 and the XNZ region (I am in the US but this is not available as a region on the site, my device is wifi only so I didn't think it mattered)
I selected the BL, AP, and CSC and clicked start
There is no indication on the tablet that anything is happening
Odin last says "Initialization..."
It stays this way for up to an hour before I stop the operation
I have tried turning on the repartition and nand erase all options, but the result is the same
I have tried different USB cables
Am I missing a step here? My tablet definitely cannot enter recovery mode, I have tried all sorts of methods to try, which I think unfortunately means I can't turn on USB Debugging? Any thoughts on what happened to my tablet?
My Device:
Samsung SM-T580
Current Binary: Samsung Official
System Status: Official
FRP Lock: On
Secure Download: Enabled
Warranty Void: 0
AP SWREV: B:5 K:2 S:3
Edit: Oh, I don't care about any of the data. If that wasn't apparent already from the steps I've taken.
Edit2: The tablet was always stored in my home, which is constantly between 65 and 78 degrees farenheight, the relative humidity can fluctuate from below 50 to over 60% (a reply asked what conditions the tablet was stored, and mentioned corrosion). I would sometimes not use the tablet for an extended period of time.
Thanks!
For example, they could corrode the sockets.
You did not write how long and under what conditions the tablet was stored.

I've updated my post with the conditions my tablet was stored in. If corrosion is a problem, I'm never purchasing a Samsung tablet again because that would be appalling considering how well taken care of it was.
