I received a customer's phone and he said it wont boot. He didn't speak very good English but i checked it out and we accepted it as a flash. Anyways when you go to boot it says 'installing system update' and after a few moments says 'no command' then goes to recovery mode. I tried to flash a few different firmwares and they were successful but when I went to boot it it said 'installing system update' but actually has a percentage bar. But after it finishes it says 'no command' again. While in odin mode it also says FRP Lock is on. I'm assuming this guy tried some **** and failed and brought it to us as last hope. Any advice on what to try next?
Hi first you need to make FRP to do that you need to have adb enabled
Flash this adb enable file with odin.

Now you can remove frp with realterm or any other tool or box.

I had another tool if that doesn't work .
Hello,
I've Samsung Galaxy SM-J701F/DS and i did factory reset and started getting into panic mode. So, I tried to flash stock ROM through odin and I only selected AP and left other files like Bl, CP and CSC. Thus it took longer time without any result so, I closed the odin. Since then my phone only boots in download mode.
And while trying recovery or normal boot I get " Error Cannot Update Software ".
I used this ROM:
https://www.sammobile.com/firmwares/...-nxt/SM-J701F
And now my phone is showing as Samsung USB Modem while plugging in PC.
So today I wanted to root my phone and flash a custom rom. I went to the PC and setted my phone in download mode, opened Odin, downloaded the TWRP from the S9 (SM-G960F) XDA Forum then I've selected on AP (Odin) the .img file but it gave me error. My phone said "Custom Binary (USERDATA) blocked by FRP lock" and now when I try to boot it says "An error occurred while updating the device software use the emergency recovery function" but it won't be recognized by the tool. I'm basically stuck with my phone giving me this message with a blue background.
Edit: Nevermind, I fixed it and got TWRP to work.
I have a Samsung Galaxy S7 and can get into download mode. That's about it. The phone is NOT rooted and debugging is NOT on.
Cannot get into regular startup (error says something about smart switch, after an unsuccessful wipe)
Cannot get into recovery mode. It gives me an error.
Luckily I still have the box which says the mode number: G930W8VLU2APK3 , and I bought it from a Bell store so I was able to find the correct firmware, however I get a Rev check error when flashing it via Odin. I even tried a few variants and am getting the same error.
Any suggestions? I have tried flashing without Bootloader but still get the same error
Hi folks,
I've got a new A52 5G and wanted it to root. TWRP couldn't be used, because each and every possible solution failed. I even got stuck at boot with a message that the recovery couldn't get startet, even if I just restarted the phone without pressing the keys and without plugged USB cable.
Even flashing the original firmware was not possible. Then I tried to lock the bootloader again and flashing of the firmware was going on with odin. Puh... Then I used the Magisk method without TWRP to change die boot.img with magisk and load it in Odin. Success! I had now root on the phone. Yesterday I read about uninstall Magisk and install it afterwards on the B partition for updating the firmware over OTA. But accidentally I pressed the button below "uninstall" and it performed imediately. Now my phone is dead again... With unlocked Bootloader it is stuck in a bootload and I can start the Samsung recovery mode to wipe the cache for example. I wiped the phone completely, but it is still stucked in a bootloop.
Then I tried my first method: Just lock the Bootloader again (in the download mode) and then flash the new firmware with odin. But Odin either crashes or is giving me instantly the message "failed".
When I'm trying to start the phone (it happened also after locking the bootloader) i'm getting the download screen and the message with a big red !
"partition boot
Reason boot: Hash of data does not match digest in descriptor. [2nd] (3)
Calculated Hash of (boot) : 23B8CFD554, (VEMETA) : D23E59ACD6
CUSTOM boot
VBMETA A526BXXU1AUCA, 38851814R"
Now I unlocked the bootloader again, to access the recovery mode so I can turn it off. Otherwise its stuck in the damn bootloop. Can't flash and wipe doesn't help either.
Please help me somehow -.-
why did you u

why did you OTA update the rooted phone
it is clearly written that your phone might brick.
what happened to you is your boot.img file is replaced with the newer version try replacing with the boot.img file of previous version.
I didn't, because I get (as always, this is not my first rooted phone) the message, that the system has been changed. OTA is not working and I read that uninstall magisk, update the phone and BEFORE reboot install magisk again on partition B. But I accidentaly pressed the second option in magisk, complete uninstall or how its name is. Didn't expected, that its start instantly without a "Caution" message.
Uninstalling Magisk should not bring my phone into a bootloop anyway, even if I wipe the cache. Or am I wrong?

That is the problem how do I do that, when everything with odin stops imediately or odin crashes.
Does Odin give you any error messages? Are you patching all of the files for the firmware AP BL CP & CSC? Are you making sure to use the non home CSC? Have you tried using Samsung Smart Switch to recover your phone?
Smart Switch didn't recognize the phone. The only error on Odin was "succeed 0 / failed 1).
It worked with Windows 10 notebook and the USB C Port. However it didn't worked on Win 7 and regular USB Ports. Very strange. Well, but now I have the original firmware and again lots of bloatware. TWRP doesn't work, impossible to boot with it. How can I root the A52 with Magisk that way, to deactivate it - if needed - for firmware updates? The phone doesn't has A/B partition.
Same happened to me.
So, I have an A52 Indian version and want to flash the Canadian firmware. I downloaded different versions of the Canadian firmware and used Odin to flash. I followed the instructions on downloading the files, loading them into Odin,hit Start and it kept failing. It was giving an error message regarding a repartitioning error. Could this be due to having to tick "OEM Unlocking" in developer options which I hadn't done?
Hey, is your phone still stuck ?
