Hi, I recently tried to root my Samsung S7 Active G891A. I download something that was supposed to "root" my phone and installed it via Odin. After the install it said complete and I tried to boot up my Phone and it wouldn't boot up. It was go to the screen where its says "Samsung S7 Active" then the screen would go dark and it would replay again. I've tried reseting my cache and Factory Reseting everything but that doesn't work via recovery mode. Im guessing my original firmware is corrupted but I dont know how to go about fixing that. Can some please help me?

Greetings and welcome to assist. Is this the guide you used to root your phone ? If you hsve flashed the wrong files with odin that is probably the issue. The easiest way to make your phone boot is with smartswitch emergency firmware recovery
Good Luck

Hey guys,
Is data recovery possible after a flash? Also, what is wrong? I have searched but no answer directly hits on this. I am not a tech guy- Biology- sorry for that ahead. To the issue, I dlowded a software update to my Galaxy s3.....and boom froze on Samsung screen. I can turn phone off and on. It would not boot past Samsung. So I went into cache partrition, and tried a system reboot- cannot. So then I seen a program that supposively recovers data after factory reset if you do nothing else to the phone. However, problem I hit te dreaded factory reset- nothing. Over a software update? My computer is not recognizing the device. So I went to Samsung, they tried installing software, however, the computers were recognizing, but not connecting. One tech said they did not have flash- I went back again, the othertech said they did. Anywho, after 4 days, I forked my phone over to a repair guy. He I believe tried Odin- as it currently sits in odin mode. Now it was getting into download mode- but ow I have this message- " Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again." A samsung guy mentioned it might be able to be flashed, as my concern data- not backed up. This info is pretty important, as I have several contacts and mssgs. The two modes my phone can go into: Odin and recovery. I could really use the help, on both saving data, and getting the phone to fire- as it might be able to- but data?
Thanks in advance.
Use helium for recovery data

Before or after the a Flash? Thanks for the reply.
Hi all,
I have a standard s6 with stock EE (UK) firmware 6.0.1 installed (non rooted) . The other day I put it in UPSM mode. But soon after, the phone just restarted and now just gets stuck on the Samsung logo screen. If left long enough, the phone vibrates once.
I can get in to both recovery and 'download' mode. Tried wipe cache and flashing the same firmware using odin. Odin goes through successfully but the device still gets stuck at the same place.
The main thing is that I need to get the data off the phone. Any ideas how I can do this,( I don't think USB debugging or developer mode were/are enabled) ? Or indeed remedy the boot loop?
Thanks
Any advice on this folks?
If anyone knows of a way I can recover the data at least, whilst the phone is in this state, would be appreciated. The only thing I have not tried yet is a factory reset from recovery (because of data loss). If I am able to recover the data and then a factory reset fails, I am still under warranty so that should not be an issue.
Thanks in advanced.
Hello All,
This may seem like a regular problem but it's not.
I own a Galaxy note edge N915G - Indian model. not rooted even once.
This morning when I reset my phone and I was reinstalling the apps, my phone was working fine, but when I initialized WhatsApp my phone went into BOOTLOOP.
I tried installing the official latest firmware from sam mobile N915GXXU1DPK6_N915GODD1DPK3_INS for my phone using Odin 3.10.6.
Also, factory reset and cache cleared after flashing the stock rom,
But I still don't have any luck in clearing the boot loop.
As my phone is not rooted I don't know what else to do.
I tried with Odin 3.12.5 too. but no luck.
I also tried the firmware N915GXXU1DPK6_N915GODD1DPK3_INU from sam mobile but it is still stuck in the bootloop.
I can go in the recovery and the download mode but cannot get it fired up.
I have nowhere to go as the phone is out of warranty just this month.
Is there any other solution for this or something I have to do differently?
Please help me as I am out of my country now and I have no phone to use other than this.
Hi Guys,
My relative has a stock Australian S7 SM-G930F which has an issue trying to boot, it was running standard optus firmware and just stopped working one day, stuck at samsung screen.
So I tried to perform a factory reset from recovery and still same issue it cannot access the EFS partition.
So I go to try to load a stock firmware and same issue.
I found this article which looks like it should restore access to the EFS partition https://forum.xda-developers.com/galaxy-s3/general/how-to-fix-efailed-to-mount-efs-invalid-t2858056 but whenever I try to load a custom recovery I get FRP lock so it looks like from my reading I am stuck and my relative now has a flashy brick?
Cannot seem to get ADB to work I assume because it has never had USB debugging enabled.
It has never been rooted, custom firmware or anything.
The only thing that works is download mode with ODIN. But since EFS is corrupted/inaccessible and FRP is locked I don't see a solution.
Anyone come across this issue before and how to solve?
It is not under warranty and is slightly damaged so not worth sending back for repair.
Same case
Exactly the same case with me. My device stuck on "Galaxy S7 logo", when I tried to enter recovery mode , got message failed to mount /efs, already tried to flashing with original rom, but still the same.
Then I tried to install twrp,but I got FRP locked.
If anyone can help us maybe there's some steps that I've missed
My S8 randomly froze yesterday, shut off, and wont boot since. I tried a factory reset with twrp, didnt work. Normally, I'd just reinstall the firmware, but Odin doesn't detect my phone. So now, I have a few questions: What could the original problem be, how to fix that, why doesnt Odin detect my phone, and how fix that, and also additionally how to see my model number in twrp because I'm not 100% sure about it. Any help is appreciated. Thank you!
