[Q] Bricked - please help!

Hey guys,
I managed to f*** up my phone and don't know exactly what went wrong. I'm worried it's a hard brick, but don't know for sure. It won't turn on though, which is freaking me out. I hope one of y'all can help.
So I was running CM10.1 for a long time and everything was great. I eventually installed an update through the built-in CM updater app, decided I didn't like it, and attempted to re-install through the .zip I still had on my sdcard. I'm still not sure why, but doing so put me in a boot-loop. I was pretty busy at the time so just flashed back to stock. Wasn't ideal, but worked fine.
So now I have some free time and decided I'd try to re-install CM. Prior to the install attempt, I was running 4.1.2 stock, rooted and with an unlocked bootloader. Here's what I did:
1: Flashed the VRALEC bootloader, as recommended by the CM wiki, through Odin.
-At this point, everything still worked OK. I think this next step is where I went wrong.
2: Flashed the VRALF2 kernel through Odin.
-This is what I think I did wrong. After I flashed it, instead of booting up the phone got past the Galaxy S3 graphic then the LED just slowly changed from blue to light blue and back. Either way, I still was able to do the following steps.
3: Flashed CWM 6.0.1.2 through Odin.
4: Installed CM10.2 and gapps from recovery.
5: Rebooted, stuck in a boot-loop showing the CM logo.
So hindsight being 20/20, this is where I should have stopped and asked for help. Instead, I decided that I'd try to fix it myself and tried to flash back to stock. When I tried to do so, Odin said it failed. I then reflashed the VRALEC bootloader, again through Odin. This was successful, but after it rebooted, it showed the Galaxy S3 graphic for a bit and then went blank. Since then, I can't get the phone to turn on or enter download or recovery modes.
Can anyone help? I'm really worried I hard-bricked my phone. What do I need to do / where can I go from here?

Update - Maybe not hard-bricked!

So I've managed to get the phone into recovery mode, which is the factory recovery (not CWM). And I can also get into download mode. But when I start up the phone, it stops at the "Samsung Galaxy S III" graphic and just stays there. From that screen, I can only get it to turn off by taking out the battery.
Hopefully this means I'm not hard-bricked. Does anyone know what I can do from here to get it functional again?

If you can get into recovery/download, you are definitely not hardbricked. Try to do a factory reset in recovery. If that doesn't work try to ODIN a full stock image.
*your internal storage will be wiped with a factory reset (obviously).
I'm pretty sure they recommend flashing the newer CM's from the MF1 base. I might be making that up though.

Sounds like you forgot to flash something, check the thread you used again

If you have a blue led light after the Samsung galaxy s3 screen when it goes black then you don't have the proper drivers for your screen which would be in the file you didn't flash

Tried the factory reset, ended up in the same spot. So, next I'll try flashing back to stock.
I've done this before, but after the scare earlier I'm being overly paranoid - am I going to need to flash a different kernel? Or is it gonna be enough to just flash something like the VRBMF1 image?

Flash back to stock 4.1.2, use Casual to root and unlock, and get a recovery.

So this is another dumb question. But having just downloaded the newest version of Java to my Windows 7 computer, I still can't get Casual to open. Instead, this command prompt dialogue box pops up for a little bit then disappears. Nothing else happens after that. I'm opening it with JRE 1.7 - should I be doing something differently?
Edit - I just opened it in terminal, got it going fine, but can't get Casual to recognize my phone. I'm about to update the drivers, see if that does the trick.

If it still doesn't work, try the slightly older version of Casual: http://rootzwiki.com/topic/44201-★-casualroot-unlock-recovery-1-click-all-otas★/

Note 5 bricked

Good Morning
I have spent all night trying to determine how to unbrick my brand new Note 5. I was able to use Odin to root the device, but then when I rebooted after trying to install TWRP, it is just plain bricked. I cannot get Odin to install any firmware, i can boot into recovery mode, but wiping data and cache does nothing. I get a constant bootloop that says Kernel is not SEAndroid and Custom Binary blocked by FRP.
Every time i plug the phone into the laptop, it says that the USB device is unrecognizable. I have installed Samsung USB drivers. I am just at a loss, Odin fails every time.
I will admit that I am a pathetic noob and should have waiting a longer time to do this. I had just given up my iPhone on Sunday.
Any help would be appreciated.

Delete the Samsung drivers and then reinstall them, that may get your computer to recognize your device. As far as the rest idk

I have done that several times so far. The thing is, the system says not reco. but Odin sees it. I can boot into both download and recovery. So is this considered soft or hard bricked?

You can't brick your phone. That terminology is silly.
What Odin are you using? You have to use 10.0.7.1 something like that.
Also make sure you are flashing your device model firmware.
Try another computer if Odin fails on your current computer.

I have used Odin 3.09 and 3.10.7. I got my firmware from Sammobile and search by my device model SM-N920T. I have tried this on two different machines, Win8 and Win10. Someone on another thread asked me to try a few different ways to attempt so I will try this:
One "trick" that might work:
Without your phone plugged-in to your PC,
Set up ODIN w/the firmware of choice,boot-up your phone,plug-in to PC,then,boot into download mode while plugged-in.
Try this,or several variations of it.
I had to do this using ODIN on my Note5 to get programs/ROMS to load up.
This isn't common,but,I've seen a few other people have to do this,it's likely a PC-Driver related thing (I have a somewhat uncommon PC,a Gateway,that may explain it)............from Kolio on AndroidForums

If it's bootlooping, you must go into stock recovery and wipe data, factory reset!

I have gone into recovery and wiped data however that does nothing. here are the steps I have done:
Power phone on holding the volume up, home and power buttons - it installs system update
-wipe data/factory reset
I get red line: E: failed to mount /preload (No such file or directory)
then using what was suggested in prior post
When trying to flash with Odin it gets to cm.bin and then fails.

Have you tried re-downloading the firmware from sammobile.com? Try a different build number?

It happened to me too i was scared i thought ihad messed my phone up but I found a solution

You can try different usb port and different cable too. And which tab you use for the installing the stock firmware? FRP lock is here because you didnt open the oem unlock before the installing customized file. You have to install stock with odin. and then factory reset and then you can open the device get the development settings and disable the oem unlock.

Sure you can brick your phone, and the only thing silly about the term brick is the over use of it.

G955FD Softbricked. OEM Unlock is Disabled.

Can I get some help? I bricked my phone because I was trying to install twrp. It flashed but I got TWRP cant install.Because. OEM locked.
It flashed. Great. But now IT STILL DOESNT BOOT. I'm stuck at NO COMMAND, it keeps restarting after 20-30 seconds of showing no command. and it's looping all over.*
i flashed stock firmware.It is flashed.Then reboot.Then install system update.Then Erasing.Then rebooting.Then NO COMMAND.Then reboot itselve recovery mode.Then i wiped factoory and cache.Then press rwboot to system.Then Samsung Galaxy S8 Plus.Then install system update.Erasing.No Command. etc. Keeps rebooting. its on NO command screen. It just restarts. Doesnt boot. I want to enable OEM Unlock. I installed combination binary. But not appear in Developer Mode.
i flash atock with Kies emergency.I flash different stock firmware from updato.com. But nothing happend.

I'm a little confused.

KIES says that. (THR) Stock. i downloaded it and flashed with Odin. Then reboot. Then system install update. Then Erasing. Then reboot and No Command! 30 seconds keeps rebooting itself 30 seconds interval Random.
I did factory format, cache clear. then the same problem. i want to install twrp recovery with oden. It says Oem Lock. Not allowed. But i flashed Combinary file. I can get into system and i to developer mode but dosnt seem OEM UNLOCK that ll do enable it.

Ok mate, but if you press Vol- + Bixby + power for couple of seconds, can you access to download mode? If you can, I think you'll have to install the firmware all over again.

Try flashing using latest firmware from sammobile. Use Odin to flash all the files contained in firmware download. Make sure you get latest firmware for your carrier. Google how to flash using Odin. Hope this gets you in the right direction. Good luck finding what u need, do copious amounts of research before attempting any rooting of devices and if all steps aren't clear as day to you then do not attempt it unless you don't mind buying multiple expensive phones to tinker with.

Did OP find a fix to this problem?
I am experiencing a similar issue. Picked my phone up to find had randomly gone into a boot loop. Tried soft reset, cache wipe, factory reset - all successful but the phone would still reboot and be stuck on device model screen. Next I decided to flash the device with stock firmware. The flash passed in Odin, the phone then rebooted, loaded to device model screen, then a screen appeared saying "installing updates" which would make it to 25% then crash. After this the phone keeps booting, shows a screen with a dead android icon and says "no command" or "error". I have tried to flash the device using Oreo and Nougat firmware but have failed every time (although the flash did pass in Odin)
Any help would be greatly appreciated as I would rather not buy a new phone due to a random hardware fault which is out of my control.

Galaxy S6 0mb TWRP / no OS! Help wanted, i do not want an brick

I have Galaxy S6 and when i tried to install new ROM via usb-otg stick something strange happened and now my whole phone is unusable.
TWRP just says 0mb for internal storage and i cannot install anything since i cannot mount anything. I have looked pretty much all the "fixes" but nothing has helped so far :\ I have tried to format, wipe, change partition type, install, etc. And nothing has helped me so far. So if there are any ideas left please help :]
I think i still have root and when entering TWRP it does not ask password since i have done dm-verify long time ago.
Here is video showing some of the things: https://youtu.be/wXVVRBmRROU

go to download mode and flash stock firmware with ODIN. than flash twrp, enter recovery (twrp) before system. and boot to stock.
than try again.

Hi!
I got stock firmware from Updato and then began to flash with Odin and it seemed that it would work since it was actually doing something at first (while trying to flash ROM's Odin crashes) but then it gave an error and stopped :\ Here is an picture of Odin's log.

I guess you had better restore factory image, make sure the system comes back. then flash updated version OS.
You can trying to use ODIN to do that. or using fastboot flash .....

Okay, i have new problem. After i tried to flash with odin now i got only one place i can boot into and it looks like this:
I downloaded Smart Switch and entered emergency recovery but i was met with this screen and i have no idea from where to get the code.

in smart switch emergency upgrade and initialization, if will ask model and S/N.
model is SM-G920F and S/N in on the back of the phone. all caps.

Smart Switch did not even have that option but i tried it with Kies and got this

smart switch should have same option. I found googling that in never versions that option was not functional due to Samsung not wanting people to debrand their phone. so older version is needed.
just got mine in a similar bootloop.
can u get into download mode?
If phone can't turn off do this:
- hold volume down + power, (that is reboot)
- as the screen goes black move finger to volume up + home key.
that should get you to download mode. now use odin to flash stock firmware.

I tried that before and i tried it now again and same result:

is that firmware higher version than one previously installed?? i had that issue once!
G920FXXE5EQJ1........ try with any other with higher number. UK (BTU) is G920FXXU6ERC9

The problem is hidden.img file.
Search in google "galaxy s6 hidden.img fail" and solved.

But then trouble started again. Boot screen came up and then text and mount problems like "failed to mount efs (no such file or directory)" :crying:
Here is the video about it, anything i could do now? I installed TWRP and it still says internal storage 0mb and formatting has no effect.
Video - https://youtu.be/OBfhTRWUZeU

I got little progress. I found the S/N from back of the phone with torch which i could not see without (Thanks for Augustin @ XDA Discord for this!) and then i tried to use Smart Switch but it does not recognize the phone and only option is "Emergency Firmware Recovery" and it needs some recovery code.
Then i tried Kies and it does not detect the device either and i tried the option "Firmware Upgrade and Initialization" and typed out model and S/N and after that it said "SM-G920F" does not support initializing"
So anyone knows what i could do now? Seems like i am running out of options here
Augustin also said that i should try pit but i have never used that feature in Odin so help with that would be awesome if it can remedy this situation somehow

You need the .pit file according to your csc. Found it here: https://forum.xda-developers.com/galaxy-s6/general/g920f-pit-file-banded-firmwares-t3118459

Thanks a lot! Finally using pit got the partitions right and phone is working like a charm now! :]

This might be a bit late but I am also currently in the same situation with my S6. Somewhere in the thread it said something about pit files but I don't really understand what to do. For reference, my issue is the exact same as OP's with the unmountable partitions and unbootable system. Would someone be kind enough to help out? My device is a SM-G920F from Vodafone (UK)

Help rescuing a S7 in boot loop and no access to recovery

Hello guys
First of all, thanks to everyone who shares their knowledge and experiences here on XDA. I've been learning stuff here for years, and every time I made a mistake, I could find a solution, but I'm afraid this time the noob here has made too many mistakes.
My S7 G930F DBT stock is in a boot loop, with the "no command" screen, and the only thing I'm able to do is access download*mode. I would like your help to figure out if there's still something I can do on my own.
So, what happened was that I followed this tutorial about a year ago and converted*my S7 to dual sim. I encountered some issues, one of them being that I wasn't able to keep TWRP installed (the system removed it after the first boot), but in the end I was able to make the phone work again, dual sim. This week, I was having some issues with short battery life and wanted to boot into recovery to wipe cache. I tried that and the boot loop started, and when I tried to access recovery it said that there*was no recovery (I can't recall the exact*message). Since then I tried some things*and realized later I made things worse:
- I tried to flash the stock rom via Odin, but did so with the latest firmware (S8), not with the one on the phone (S4).
- Tried to flash all except the BL file on Odin- I tried to flash TWRP, but it failed because of FRP lock.
- I tried to flash a combination rom, but since I had flashed S8, I couldn't*because the latest combination available is U5
- I'm not sure if it's relevant or not, but when following the dual sim conversion tutorial last year and editing the cert file, the serial number was 00000. I kept it that way because I didn't realize it's written on the back of the phone (duh).
Nothing worked, the phone is still in boot loop, I can't access recovery (not even the "no recovery*message" shows up anymore) and I can only put it in download mode. I thought about maybe removing FRP Lock with the z3x 29.5 I used for the dual sim tutorial, flash TWRP and follow all the steps again, to put the serial number in the cert file, but I'm not sure it would be possible, since I flashed a newer firmware.
So, what do you think? Have I messed up beyond repair this time?
Thanks in advance

Hello, so if you've flashed a newer bootloader than the one in the tutorial then yes it's game over for dual SIM as there isn't a newer version of that bootloader and there isn't going to be. The S7 is getting on abit now.
The best you can now hope for is to install the latest German firmware and have your phone working as a single SIM again.
To exit no command press volume up + power.
When you install TWRP stock recovery is removed. When you uninstall TWRP stock recovery is still missing until you flash stock firmware, that's why you have No command.

Hello, so if you've flashed a newer bootloader than the one in the tutorial then yes it's game over for dual SIM as there isn't a newer version of that bootloader and there isn't going to be. The S7 is getting on abit now.
The best you can now hope for is to install the latest German firmware and have your phone working as a single SIM again.
To exit no command press volume up + power.

Thanks for replying!
I have no problem loosing dual sim, as long as I can get it back up. When I press volume up + power, nothing happens, it only turns off completely. I flashed the the latest firmware again (G930FXXS8ETC6 - CSC file, not HOME_CSC). But the result was the same, "no command" screen and no access to recovery, I tried volume up + power and volume up + home button + power, at the same time and alternating.

I was able to get to were the recovery was supposed to be and this is the error it's showing:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I flashed the phone in Odin once again, this time with "nand erase" and "repartition" checked, and the pit file in the third tab. But it didn't work, afterwards the "no command" screen poped up and the same error showed up when trying to access recovery. Tried to flash TWRP again and got the FRP lock message. Nothing changed, basically.
I thought about finding a way to bypass FRP and install TWRP, but there's some shady stuff online on how to do it. The Z3x tool used in the dual sim tutorial has an option for that, but it shows "card error" when I try it and nothing happens.
So, I'm kinda lost here, any suggestion on the next steps would be much appreciated.

I tried to find a way to bypass FRP, tried many tools, like Z3X and Miracle, but it didn't work. The best I could get out of two of these softwares was a "Custom Binary(Userdata) Blocked by FRP Lock" line in download mode when the procedure was finished, not even a reboot. When I manually reboot the phone after getting this message, it shows something different, "An error has occurred while updating" blue screen saying to use SmartSwitch, but that obviously doesn't work either.

It's unlikely you'll be able to bypass FRP lock with any tool as most don't work anymore.
You just need to flash the latest firmware for your region with Odin. Boot into download mode to do this, can you still access download mode?
After a successful flash the FRP lock will still ask for the Google account and password used with the phone. Follow the steps and your phone should start normally.
It does not matter what modifications you have done prior, the default recovery is always flash latest firmware with Odin.
In future REMOVE Google account from phone BEFORE modification.

It wasn't intentional, the phone was working fine and I was logged in my Google account, but the battery life was getting shorter. I just wanted to wipe cache to try and fix that. When I tried to boot to recovery, the boot loop started.
I think that happened because of the dual sim modification last year, I must have done something wrong and the phone lost the recovery mode or something. But the first thing I did was flashing the latest stock firmware, and after that I couldn't get into the system anymore. I probably should have flashed the same binary I had installed, at least it would give me the combination file option.
Download mode is the only thing working. The FRP lock bypass route was the best I could come up with, since it would allow to install TWRP, access to ADB, etc

I understand all that you've said the only solution is to install correct firmware with Odin via download mode then sign into Google account.
