Root Attempt = Reboot Loop - Verizon Samsung Galaxy S7 Questions & Answers

Hi all, sorry if this is not the proper place for this.
I attempted to root an old Verizon GS7 by using Odin and downloading the Root AP file. After that the phone is stuck in a reboot loop. I can get it to go back into the download mode (Pwr + Vol Down + Home) where I am trying to just recover it to stock.
The problem I'm having is that no matter where I've gotten the supposed "Official" Verizon ROM, it will not download with Odin.
I've tried an older ROM and the download fails with a version check error on the phone screen.
When I tried the latest version (G930VVRS4CRI1 as told to me by a Verizon support person) I get an "Unsupport dev_type" on the phone.
I'm open to any and all suggestions on how I can get myself out of the corner I've painted myself into! :fingers-crossed:
TIA!

I resolved my problem by using the 3.13.1 version of Odin. I was previously using the 3.12 Prince Comsy version.
I FINALLY realized that I could search for the "Unsuport dev_type" string and it led me to the solution.

[Q] Bootlooped my phone :(

I have a Verizon Samsung Galaxy S4 (SCH-I545) which I previously rooted via the Open1Your1Eyes0 pwn script. Everything was great except I wanted to update to the latest version and my phone failed with each attempt. I tried to unroot it using Odin to flash the VRUAMDK_NoWipe.tar.md5 stock ROM image.
That failed and now it's stuck on the ODIN MODE "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again." message screen. The phone won't boot. If I hold Vol Down I can still go to the Downloading firmware screen, but I've tried flashing 3 other stock ROM's and nothing will work.
Any suggestions?
You are in the wrong forum. You need to go the verizon part.

[Q] i9505 Soft Brick Help - Stuck on Samsung logo (Rooted)

Okay first post on this website.
4.4.2, i9505
So, as i am a compete android n00b, i rooted my s4 with the KingoRoot tool as i thought it was an easy method, later i found out ChainFire made an easy auto root .
After i rooted with the kingo my device would randomly reboot, when i called someone, when i locked my phone and random stages throughout the day.
After some reading online i found the solution was to re-flash my phone to stock fireware. so i downloaded odin, drivers, fireware from sam and tried to re-flash it. however my phone failed after aboot.mbn. I then got the unexpected error saying the phone had to be plugged into kies etc.
I then used "philz_touch_6.07.9-i9300.tar.md5" to get rid of the error message which worked. however the phone still would radnomly restart.
Again i turnrf to the web to find a solution for the radnom booting and found this -

1. The error that give u ODIN is coz you are trying to flash an older firmware that the one you have installed in your device.
2. You have to flash a STOCK recovery. Flash this file via ODIN in PDA/AP (like in the pic 1 attached): HERE.
3. Turn off your device manually when the process finish. Boot it into STOCK RECOVERY by pressing and holding Volume Up, Home and Power.
4. Take a look the CSC (pic 2). "Applied the CSC-code: ............" <- This is your REAL CSC. Turn off your device again manually and boot it into DOWNLOAD MODE by pressing and holding Volume Down, Home and Power.
5. Go to Sammobile and download the LATEST firmware for your device with correct CSC and flash it via ODIN.
6. About KNOX and reboots: Delete all KNOX reminds less "Lib = libknox_encryption.so".
7. Good luck

My Galaxy S5 appears to be unflashable/unrootable, any advice?

Hi,
I recently got me a Galaxy S5 (SM-G900F) and the first thing i wanted to do was installing CM13 as I always do with my new phones. However, when i followed te steps on CM wiki using Heimdall to flash TWRP the blue bar of the downlaod mode increases a small bit, then stops and in the command promt it says something about error with finding PIT. After trying this for three times i decided to go with Odin, which I do prefer anyways.
I tried flashing TWRP , the blue bar is filling to 100% but then on the little screen where Odin usually states FAIL! or PASS! it just says RESET! and my phone is restarting. Shortly after it restarded you can see the RESET! turning to PASS!, but when I tried checking in TWRP is installed, it wasn't. I tried it again and then Odin suddenly says FAIL! After restarting my phone it says "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again". I couldnt even enter download mode anymore till I tried if getting out the battery would work. I could enter download mode again and flashed the same TWRP on my phone again, and aigain it says RESET! but after that my phone worked again. I tried flashing with another version of Odin and TWRP but same thing happened - First run it said RESET!, second run FAIL!.
I thought maybe rooting the device and installing TWRP via their app afterwards could do the trick. So i tried flashing Autoroot with Odin but it made my phone showing a screen with Samsung logo and in the upper left corner something about recovery mode, seemed to be a loop/freeze. So i took out the battery again and flashed TWRP and that solved the problem again. At last I tried rooting by using TowelRoot but it says the service is not available for my device, even though S5 is listed as a supported device.
I really have no idea what to do anymore, would be very grateful if someone could come up with a solution.
BTW: Is it possible to flash CM13 without using custom recovery by using stock recovery?
Greetings

RESET! is basically the same thing as PASS! What version of TWRP are you installing? The keis screen you got is the same as download mode. Why are you using heimdal? your idea to go with Odin was a good one. Anyways, download TWRP 3.0.2 (not 3.0.2-1 or 3.0.2-2 as they are buggy) and flash it in Odin, reboot to recovery and install the ROM you like, of course following its specific install instructions. No, you cant install a custom rom with stock recovery
Thanks for your answer, meanwhile i managed to fix this problem. Had to flash the latest Firmware because twrp (could just install the oldest version otherwise I had no option to boot into recovery at all) said no OS installed. After rooting via Odin worked like it's supposed to.
Why did I use Heimdall? Because I wanted to stick to CM-wikis instruction and they used Heimdall.

T280 - Can not flash back to stock, secure check fail (boot)

Summary: My tablet is soft-brick now. Can only access to Download (ODIN) mode. I have tried 2,3 different firmwares, tried 3 versions of ODIN. But it doesn't work.
Here is the story:
I bought this tablet from bestbuy (USA)
I only wanted to root my tab A 7.0 SM-T280.
I enabled the OEN unlock from the developer mode.
Then I tried to flash the TWRP by the tutorial from this topic by @ashyx :
To install TWRP:
1. Flash with ODIN 3.10.7 in the AP slot.
Uncheck Auto reboot.
2. Load the respective file below into the AP slot and hit start.
3. After flashing when ODIN says PASS immediately reboot to recovery by holding POWER + HOME + VOL DOWN.
As soon as the screen goes blank change to VOL UP whilst still holding the other buttons.
You should now see TWRP recovery.
TWRP_3.0.2-1_SM-T280_261016

After flashing, on the download mode it showed: "SECURE CHECK FAIL: (RECOVERY)", then I reboot into recovery mode to access the TWRP but it said: "RECOVERY IS NOT SEANDROID FORCEFUL (although in ashyx topic said the SECURE FAIL is fine).
I still was able to reboot into the system this time.
And then I thought I should try another way. And then I came up with the TINKER ROM.
I tried to flash the Rom (v5) but somehow ODIN said FAIL.
I COULD NOT access the system since then.
Bu @zenful 's advices, I tried some different stock firmwares and different versions of ODIN just to get back to normal, but it never works.
Every time I flash, it always has the same problem:
- First try, ODIN fails at:
sboot.img
sboot2.img
complete (write) failed... (I don't remember though)
And in the download mode screen (from the phone) said:
SECURE CHECK FAIL (SBOOT)
SECURE CHECK FAIL (SBOOT2)
- Second try, ODIN fails at:
boot.img
system.img
Complete (write) fail...
And in the screen said:
SECURE CHECK FAIL (BOOT)
SECURE CHECK FAIL (RECOVERY)
I also tried emergency recovery mode in smart switch but it didn't solved the problem. One good thing (after I entered the tablet model and serial number) is that it showed "PHONE: QA4 CSC: PH3 (XAR)"
______________
I'm pretty sure that the problem doesn't come from fw nor from ODIN since I downloaded the fws from sammobile and updato and downloaded ODIN from xda (the latest version from samsungodin.com)
I'm seriously need a help right now. I just wanna have a rooted tablet so I can play game with my ps4 controller.
I have experienced with these flashing business. I rooted my galaxy s2, HTC desire c, HTC evo, etc. and so on, but have never done rooting in the last 1 year. I can attach some snapshots if you guys request

Try this: download your desire firmware via samfirm (BL+AP+CP+CSC when extracted) plus you need a pit file for your model with the same region as firmware and then flash (with 4 firmware files incl pit) via odin autoreboot+repartition+nand erase+f.reset time. At least you will get working stock tablet. It worked on my note 4 soft bricked.

And whre can I found the pit file? I dont think there is one in the internet right now.

A20e (SM-A202F) stuck in download mode - error validating footer

Hello, i hope someone can help me. My goal was to install lineageos on the A20e. So i unlocked the bootloader succesfully. Then i wanted to install TWRP. I used heimdall for flashing (with: heimdall flash --recovery twrp.img). The process ended without any errors. But since this point the phone stuck in download mode. When i restart the phone (volume down + power) the phone runs rapidly into the download mode. On the top left corner it show an error message (look at the screenshots). I tryed to flash twrp again for two or three times and one times the orange recovery - the results are the same.
I can still reach the phone via heimdall or odin. i have downloades the latest stock rom. So i hope to unbrick the phone - but until now i have no idea how to do. Please tell me, if you know some hints. You can also post if you think its hopeless and there ist no way to unbrick the phone.
Update: I have flashed the stock rom via odin succesfully. now it starts normaly. Do i want to do a next try ;-) ...
Thread can be closed...
Thank U
Jan
