Hello , have you fixed if yet?
If not i would suggest you this vidéo that i did
https:// youtu.be/8FnNIoP1tSA
Follow all thé steps and you will have a rooted device with twrp,
But bé careful all thé data will bé erased!!
If you dont want Root , you Can Always install just thé stock firmware, Use thé download links on thé vidéo ,
If you dont know what software to choose, it doesent matter thé country or thé (AFXXU6ASL),
Just use thé firmware that has thé date thé latest (and you wont have FAIL in Odin, that happens bécause thé bootloader doesent allow firmware older than thé one that is installed)

Did you download the correct a207 firmware before you extracted the stock boot.img

Well like i said the flashing goes well NO error in ODIN!, the only error is on the phone when i try to reboot to stock!

Can get S5 SM-G900T out of soft brick mode.

Hello, I have a Tmobile Samsung S5 and I am able to get into Download Mode and I have used Odin v3.09 to try to and flash Odin Flashable Full Stock from the oldest version to the latest and everytime it just boots to the Samsung S5 logo screen with the words Recovery Booting on the top upper left of the phone. The phone is also unable to get into Recovery. I tried flashing other recovers such as TWRP via Odin but I get an error stating "recovery is not seandroid enforcing"
I am beating my head up against the wall here trying to get it to boot up.
Title was meant to say CAN'T

You might not be able to get into recovery mode but when you're soft bricked you can get into download mode.
Press the key combination to get into Download Mode and keep holding them until your phone gets to the Download Mode screen.
You'll then have to redo it and if it still doesn't work then you're probably flashing a bad firmware.
Your phone may reboot a few times during this process, as it's happened to me before and I just ended up holding until about 3 or 4 reboots.
I did flash in odin in download mode using the correct firmware. I also used kies to no avail.

Make sure it's definitely the right firmware, and try using a different version of Odin perhaps?

Connect your phone to your computer by USB, and copy the file "UPDATE-SuperSU-v2.46.zip" onto your phone's SD card.
Put your phone into fastboot mode, and connect it to your computer.
Type the command "fastboot flash recovery twrp-unofficial-blu-studio-5-lte.img" and press "Enter"

Using the "Install" option in TWRP, flash the file "UPDATE-SuperSU-v2.46.zip". Once it finishes, clear the cache and reboot normally.
Your Blu Studio 5.0 LTE should now has a TWRP custom recovery, is rooted, and you can install any custom ROM you can find just like on any other phone.
JUST MAKE SURE THAT THE ROM YOU FLASH IN TWRP IS FOR THIS PHONE!!!!! I WILL NOT BE RESPONSIBLE FOR ANY BRICKED DEVICES!!!!

J5 - SM-J500M/DS - Custom binary still blocked by FRP after flash (Odin, Z3X)

Hello everyone. :good:
I will try to be brief...
I have a J5 model SM-J500M/DS with Custom binary blocked by FRP (lock: on)
The problem is:
After flash firmware using both Odin/Z3X Pro, the message screen "Custom binary blocked by FRP" still there.
1 - I tried all versions of stock roms from: sammobile (android 5.1, 6.0), SamFirm (last firmware).
2 - I tried separated firmware repair files (BL, CP, CSC, etc..)
3 - KIES and Smart Switch same alert that SM-J500M does not have support for initialization emergency:
Is there another way to turn FRP off? :crying:
Take a look the screens below:
Thank you :good:

Just solved this kind of problem yesterday download lastest Odin and lastest rom which is available for ur device .u have to uninstall Kies and smart switch they would be a trouble while working with Odin so u should uninstall them first then press volume down +power button +home button it would take u to download mode then connect ur device to PC.if Odin detects ur device then press AP in Odin and load the rom to Odin then start flashing .if the phone got into a boot loop repeat the process again and re flash the rom .it would work I had a sm-j500f which I solved with the same process .I hope it would work for u too

G-928F - Verity 0x02 and modem.bin FAIL! - History repeating...

I bought this device from a fleamarket and have the following issues :
It was (still is) FRP locked (Android 5.1.1) so I flashed the Combination ROM (COMBINATION_FA51_G928FXXU4ARA1.zip ), realizing, adb commands from "FRP_Techeligible.bat" wont work:
adb devices
adb shell content insert --uri content://settings/secure --bind name:s:user_setup_complete --bind value:s:1
adb shell am start -n com.google.android.gsf.login/
adb shell am start -n com.google.android.gsf.login.LoginActivity
pause
The Combination ROM worked just fine.
My fault, the combination ROM was for 7.x.x.
But why doesnt it work anymore ? Bootloader incompatibilities ?
I started ODIN.
So I went for the 7.0 Stock ROM (Vodafone), ending up with the "modem.bin FAIL!" in Odin.
Also I have no idea if its vodafone branded.
I renamed "hidden.img" to "hidden.img.tar" and flashed it seperately. But it did not help.
It goes to recovery and says "No Support SINGLE-SKU", Supported API:3, dm-veritfy error... failed code: 0x02"
Flashing the Combination ROM failed afterwards.
In Recovery I do now see Android 7.0 (G928FXXS5CRH1), but I get the 0x02 Verity Error on top of it.
Wiping doesnt help anymore it seems.
It will only boot into recovery and I can still enter download mode.
So I wanted to try Android 6.0.1 ROM...but it fails after "cache.img."
SYSTEM REV. CHECK FAIL- DEVICE:1, BINARY:0
So I wanted to try Android 7.0.0 ROM again...but it fails at once.
SYSTEM REV. CHECK FAIL- DEVICE:5, BINARY:4
After rebooting (device:5 binary4) I can flash the 7.0.0 ROM again, until it comes to the "modem.bin FAIL! message again...
What have I done ? :crying:
I googled for hours today and read into so many "ideas" and "solutions"...but none of them helped.
Wish I would have stayed in the Combination ROM.:silly:
Knox is still 0x0
Is there any chance to revive this device ?
Like, flash TWRP...or a custom ROM...but how, if I can only get Download Mode and Recovery and get a:
Custom Binary(RECOVERY) Blocked By FRP Lock
Kies and "Smart Switch" Software wont recognize the device.
adb wont enlist it. (anymore). Worked with combination ROM.
Odin recognizes it on com port, starts flashing, then fails.
also read using ODIN with mixed 6.x.x and 7.x.x files coudl get me "back" the old bootloader...but I gave up now and dont want to waste another day, if its useless.
I did now flash the "4 part firmware" (AP, BL, CP, CSC) G928FXXS5CRH1 (unbranded).
The download I did via the tool "samfirm" use chk32 and decrypt on downloading !
"SM-G928F_1_20180828170540_5avji4munw_fac"
ODIN worked and the phone is back booting to "An blabla attempt..." aka. FRP lock.
Booting into Recovery it now says :
"Installing system" followed by "No command"
then shows :
7.0 (G928FXXS5CRH1)
Successfully verify for dmverity hash tree

-adb still does not enlist it as device
-A reboot from "Download Mode" ends up in the Recovery Mode once
On the next reboot its back to "normal"
-Kies says please use SmartSwitch...and SmartSwitch says "USB file transfer not allowed"
So I guess its time for the 7.x.x combination ROM again...jesus...it fails in ODIN and ends up in
"E:failed to mount /cache...recovery"...blaaahhh
on boot....
Flashing "7.0 (G928FXXS5CRH1)" in 4 parts again. So, deadend ?
As I could NOT enter Recovery anymore, I couldnt wipe cache and do a factory reset....
But no, I cant flash the COMBINATION ROM anymore..........................ODIN keeps failing.
Ok, I decied to try to downgrade from 7.0 to 6.0.1, so I can use the FRP bypass again.
But where would I find a debranded 6.01 for SM-G928F in 4 parts (BL, AP, CP, CSC)
I found a ROM, takes ages to download...good night...more tomorrow...
Update :
After much googling, stumbling across tons of trojan tools by indian people, many videos that always wants you to buy a "Box" from amazon...I tried the non adviced downgrading to Android 6.0.1.
It only worked with a 4 part flash file + ODIN (I didnt even use the PIT file, as it was supposed to be) and Im now at :
6.0.1/MMB29K.G928FXXXS3BQA7 (it flashes just fine with and without the PIT file)
No verity error, no Knox triggered.
The next step was to flash the modem of 7.0 (AP), to be able to get connected to the network again.
It worked as well.
The phone still had FRP lock, so I used the "call method" to get into a SMS, send a link, open link, surf to google account manager 6 and frp.apk, done.

Note Fan Edition N935S - Stuck on looping Start Logo Screen

Hello All,
Will try to put all details to be able to get the right advise.
Recently was trying to root my N935s unlocked phone. The "Developer options → OEM unlocking" was enabled and USB bugging was enabled. However the process failed and threw me in an unrecoverable phone state.
Seeking help and advice to get back a working phone.
=========================================

Current State of Download Mode screens (after the rooting failure and boot loop has occurred)
==============================================================
Chronology of events (starting from an untampered stock phone)
1. Installed TWRP via flashing "AP" only using ODIN and was able to boot in TWRP recovery.
2. Made a complete backup of all partitions (including EFS) on external microSD card. Have it available - however somehow it is not helping.
3. Installed Magisk Apk 25.2 on the phone. Intention was to patch stock boot.img file and re-flash it to gain root by using Magisk,
4. Downloaded the below firmware files using Frija, by inputting the phone model N935S and CSC code as "SKC". Chose the latest file proposed by Frija in Auto mode.
5. Extracted boot.img from the stock AP file (from above screenshot) and transferred to phone for patching. Patched only the boot.img file.
6. After patching flashed the patched boot only (renamed and converted to TAR using 7zip) as "boot.tar" file in AP using ODIN - flashed it along with CP/BL/CSC files as from the above image.
a. This was the mistake point as the instructions were to transfer the whole AP file to the phone - get it patched inside the phone and then flash the whole AP file along with others. Somehow I totally missed it.​​7. Restarted the phone and the phone went in a bootloop or a stuck state of being only on the black Samsung Logo screen.
8. The recovery and download mode is available by using the button combinations.
====================
My attempts to restore
1. I first booted in TWRP recovery and restored from the stock backup I had taken - hoping that it would fix everything back to normal. The restoration was completed successfully - however there is no success to go beyond logo screen.
2. Went into download mode - using ODIN, flashed all the files from above screenshot (point no.4) - the flashing is completed successfully however there problem remains.
Not sure what can I do now to be able to get back a working phone.
Can someone please share a solution to a similar situation where the Magisk installation has rendered a phone bricked.
Thanks.
Was able to find excellent online phone restoration and recovery expert help and guidance - hence I was able to recover the phone.
It is now downgraded to Android 8, have lost the original serial number in he process - which is unrecoverable, however still got a working phone.
Thread closed.
