After updating around 20 apps (altogether ), I noticed the phone was not functioning normally so I tried to reboot it but now it is stuck on Google logo. I've never unlocked the phone nor used any custom roms. I'm on the latest stock rom 2.3.4
I tried removing the battery and putting it back but didn't work. Vol. up + power and then Recovery didn't work either. It gives me a triangle with ! in it and stops right there.
I also tried the USB Jig that forces the phone into downloading mode but it gave me a screen that asks (Unlock bootloader?) with some warnings but I don't know how to accept that. Niether Vol buttons nor Power button worked there
I didn't want to mess up with the phone until I hear from you guys. Please help
up.......
You might have to actually root it or use the Samsung exe back to factory. That is if you don't want to mess with it because if I ware in your position I'd be going back for a new phone. You did nothing wrong and you have 1 year warranty on it.
FYI, the triangle with ! actually is recovery. The UI is hidden until you hold power and press vol down.

Thanks man, I didn't know about that
Is wiping the data (factory reset) going to delete my stuff stored on my SD card? like pic., music, vid. etc?
and do I need to actually wipe the data or will wiping the chache only work?
Factory reset reverts your phone back to the way it was when you got it.
That means all your account settings, device settings, installed applications etc are gone. Everything stored on your SD card will remain there - it's a different storage. The good thing about our Google phones is that you only have to login to Google once and all your stuff is back.
You can try wiping the cache first and see if that works, it won't harm anything. But if that doesn't work, I'm sure a factory reset will.
Good luck.

Can you connect your device to your computer via USB and start "adb logcat" at the Terminal/Command prompt? Does it give you any kind of readout at all?
Try doing a hard reset.

One thing you should consider is just returning the phone, especially if you never flashed or rooted or unlocked bootloader.

I can perform things with Fastboot
I don't want to root or unlock the phone. Is there anything else I can do?
I tried typing Fastboot update update.zip after downloading the stock rom update 2.3.4 and putting it in the SDK tools directory but it gave me the msg "faild to upload update.zip"
Try to reset with Odin.
I have the S7270, I try to flash my device using the default firmware "S7270XXUANA2_S7270OLBANA2_S7270XXUANA2_HOME.tar" using Odin, but my device still can not be used and still bootlop. when entering cwm appear warning "did not match size '/system/csc/common/system/csc/others.xml". then when i use menu wipe cache, appear warning "error".
I do not understand why this happened, because I was given these devices by my friend. does anyone know a solution?

Have exactly the same problem with a S7270L, it seems to be a hardware problem rather than a software problem from what I've read. And I haven't found a solution yet, but if I do, I'll let you know!.
Hi guys,
I'm new here so please be patient with me. Hands were itchy few days ago, hence, I went and unlock bootloader on my phone, it unlocked without any problems and is successful, but, when I started to flash new ROM in it, it crashed and soft bricked my phone. Always show 'No OS installed' on TWRP.
I was left with no choice but to software repair it with Xperia Companion but have to relock the bootloader to do so. Xperia Companion fixed my phone up, with Andriod 7.1.1 and it works again! but whenever I press the camera button this comes up 'Error: This camera may be in use by another application. Please close the other application and try again' ...
I've tried multiple ways to do so:
1) Unlocking the boot loader again - When being switch on, it request for Andriod Password in order to unlock the phone. Which I have never set any password at boot up before.
2) Trying to flash it into TWRP to recovery mode - Whenever I do so, it goes back to 'No OS installed'
3) Trying to flash different compatible ROM - Which reverts back to "NO OS installed"
4) Re-lock boot loader - Phone works fine, everything is OK except for the Camera issue.
If anyone could help me in my situation, I would just like to get this Camera function working again. I dont mind flashing other ROM in it or whatsoever.
Please help! :crying:

Remember to unlock your bootloader, when it ask for Android Pass, simply just enter mutiple time any pass (30, not sure,), if your phone reboot after 10 times, wait for it to reboot and enter wrong pass again. After that, your phone will boot up, now you need to flash custom kernel to use camera.

Congratulations :laugh:
First of all, I'm pretty noob this days on Android so I'm very sorry guys, also english is not my first language.
My nexus was working great until today. I ended a Whatsapp Call and get a black screen, phone looks frozen (happened before). Reboot it and works fine for 5-10 minutes, after that it started to reboot itself the whole time in bootlop, stuck in the rom intro, after the Google text. My rom is one of the very first roms from Slim Roms, I'm sorry I don't remember the Android Version, but is "old".
I can access to the recovery mode tho. I tried to wipe dalvik cache and the TWRP failed, wipe and factory reset, fail as well... I don't know what else to do. I don't have any image to install in the sd, or any backup. Windows 10 recognize an "android" but can't access to it so I can't copy any file to it.
Is my phone dead or can I do something? I love this phone :crying:
Any help please? I tried using ADB and get to copy some files into the phone but still every time I try to do a wipe cache, factory reset or what ever I get a Unable to mount Data / Cache / Storage... every time the same error.
I google it and found that some people could fix that error by repairing the file system and select ext4. But I can't do that, my TWRP build is quite old (v2.6.3.4) and doesn't have that option here. Any suggestions?
Thanks btw
Me again
I've been reading forums for more than 7 hours today and trying different solutions, and nothing. But found this guy here https://androidforums.com/threads/is-my-nexus-5-dead.1099076/
He basically had the same issue as me few years ago, exactly the same, He didn't find any luck apparently.
How is it possible that a phone that can get access to TWRP or copy/flash files via ADB/Fastboot can't be saved? Theoretically in this case this is not a hard bricked, right? So? This is so so weird
It's possible that portions of the internal memory are damaged.
The only thing left to try is flash a stock ROM using ADB commands. I recommend trying a KK ROM.
No OS but twrp working
Hello friend.
If I have understood your problem correctly then you have twrp working but no os.
I found that there is an option in twrp to enable MTP. once you do that you will be able to access it. While the phone is in recovery mode connect it to the computer and it will get recognized and you can transfer zip file to it and then flash a new os.
Cheers!

Also tried that: new rom+ gapps via usb adb and the TWRP says Failed...
I mean I still have OS because every single time I try to turn on my phone the animation screen of the Slim Rom goes in. The problem is I can't install anything new, no new rom, no factory image, no new version of TWRP, I can't wipe data or cache or do a factory reset because I get a big red Failed always. Feelsbad

Try this: lock the bootloader and reboot back into the bootloader. If the bootloader remains locked, that's a good sign. If the bootloader is unlocked, that is a bad sign.

Shieeeet... So nothing to do I guess? I already ordered a new phone but if I can save this beauty would be great
It would be great to fix it but the simplest solution may be to buy a nexus 5 with a smashed screen and working motherboard. I've done this before and it's worked out well because the nexus 5 is pretty old by today's phone standards so I got it cheap.
hmm not a bad idea at all. Thank you!
Hey guys,
decided to flash the latest DBT Firmware via Odin to get back to stock completely. (G930FXXU3ESA3)
After flashing the firmware through Odin the phone reboots and then installs an update and erases data (blue background).
After a second reboot I end up with a blue screen and the simple error: "No command".
I can not get into recovery, as I end up with the same error message wether booting into recovery or the system.
I CAN however get into downloadmode and flash twrp, after that I can boot into system but I want to keep the whole system vanilla, without TWRP.
Installing TWRP keeps the device encrypted, no matter what. I can wipe, then install no-verity-encrypt and as soon as I reboot the device is encrypted again.
Ive tried: Different Firmware Version (December 2018), 3 different cables, different odin versions.
Edit: attached an Image of the message that Pops up after about 30sec on the no command screen.
Ok, so your device will take UK Unbranded BTU firmware. You can get it from a few sources and even direct from Samsung servers with Samtool.
Forget all that flashing TWRP and non verify nonsense, if you can get into download mode you can flash firmware, obviously make sure the firmware downloaded is not corrupt etc.
I've used Odin V10 -13 to flash BTU and every version flashed it correctly. Sometimes you do get that "installing update" and then "erasing" but that's fine just leave the phone for a few minutes it should eventually reboot normally.

Just tried the latest BTU with Odin 3.13.1, same problem. Its reboots into the blue screen, applying system update to about 32% and then switches to "Erasing". After about 1min it reboots, shows "Installing System update" for a second and I end up with "No command" again. And from there on it just constantly reboots into the "No command" screen.
This seems like the same problem. I can not enter stock recovery to wipe though...
Things ive tried so far:
- Different firmware Versions (all oreo since downgrading is impossible)
- Formating with pit files
- Different Odin Versions
- Unplugging and replugging the battery
- Installing TWRP, wiping data and then installing stock recovery through TWRP
Did u try in Odin nand erase and repatition option? If not try it ( make sure u have pit file extracted or downloaded from the net)

Did a efs backup through TWRP just in case, then flashed the latest DBT firmware with nand erase -> still the same problem.
I can only guess that this was caused by using a backup from another phone back when Oreo came out, this probably messed something up really badly. Very weird, im kinda lost.

Ok, from the no command screen do the following.
Hold power until phone switches off, then press power+home+volume up. The phone should now boot into original recovery screen. Select "wipe/factory reset" and then reboot device. Job done.

Tried that, recovery is simply not working. If I hold vol - + power + home to restart and switch immediatly to vol + I boot into the usual blue screen with No command. I even tried unplugging the battery to shut off the phone and boot into recovery from there but that is not working either. Sorry should have stated that more clearly.
If I flash TWRP however, I can easily boot into TWRP with the recovery button combo.

Ok it's a tricky one so one more thing I would suggest is download and install Samsung smart switch on your PC, place the phone in download mode plug it into lap top and choose emergency software recovery in smart switch
Edit. I just remembered before that try this button combo from the no command screen volume up+volume down+power.

Hmmh. Searched a lot for the version that still supported emergency recovery. (which seems to be 4.0). If I go into download mode, start smartswitch and try to use emergency recovery there is nothing for me to select.
Volume up + down and power gives me the terminal like look which I attached in the first post with all those error messages.

The EFS partition is corrupt or blank, it's the only logical explanation but the TWRP back up should solve that, without looking at it my self and running some commands i cant help your further.

TWRP backup was created after I ran into problems though. Ive checked some more things and it seems like the serial number that is displayed (in combination rom and or Z3X) is not the same SN that is printed on the back of the phone. Could this be related? And how would I go about changing it back to the one on the sticker? The IMEI is correct.
Had someone who was more into the whole thing contact me here but when I wanted to "donate" only half of what he was asking he refused to help me.

Thats because he's a scammer. Never donate to get your phone fixed! Donate to Rom developers and things you like but never to get the phone fixed, they're usually lying.
The serial number should be the same ON the phone as displayed IN phone. Tell me the story about the phone, how did you get it? what region? where are you? what firmware was installed? Can you still flash a ROM with TWRP? Can you check OEM unlock?

Pretty sure he was just trying to remote repair for a price, which is not allowed on XDA. Would obviously donated on my own if he actually fixed it.
Bought the phone unlocked directly from a provider (simply - germany - dbt - g930f) back in 2016. Tripped kn0x after a few months, installed a few custom roms until Oreo came out.
This is where I messed up I think: I used a TWRP backup from someone else that he had shared here on XDA, which probably included his /efs too.
Since then I had constant connection problems, weak internet connection, dropped calls and so on.
Broke my screen and then decided to repair it myself. Bought a new frame, screen, battery, usb-port, earpiece and vibrator - managed to assemble all of that.
I can install all latest official firmwares (bootloader 3) through Odin. If I leave it at that I have no recovery and end up with the initially shown screen and "No command".
If i install TWRP from there and simply root with magisk or apply dm-verity-fix I can boot into the stock firmware with everything working.
I can also install ROMs. Just going completely vanilla is not possible anymore. OEM Unlock is checked, USB debugging works.
Edit: What is also astounding: If I flash version DBT-G930FXXS3ERHD-20180918145033 (oldest possible Oreo Version) I can enter recovery and do a factory reset and wipe cache.
If I do that however I am stuck at the Galaxy S7 Logo, not even bootlooping.

awww.....come on man you should have said this at the start! Of course you can't use someone else's EFS data, it's unique to your handset. Custom Rom's patch some but not all EFS data that's why they work and in your case that's why Stock firmware isn't going too.
Anyway if this is the problem (and i suspect it is) there is only one way to fix it with Octopus box which can write all the important info back onto the EFS. Your IMEI, Serial, Mac address etc. Odin reads the info from the EFS prior to nand write start, if the phone serials don't match it will always fail at some point.
You can install a custom via twrp but it will not work correctly due to EFS data miss match. Octopus box is your answer.

Anyone?
I have exactly the same error with "fail to open recovery_cause(No such file or directory)#
My Tablet is now stuck with a blue "android dead" screen saying "No command".
My history to disaster:
- i've recovered a "broken" Samsung Tablet (sm-T585) with corrupted file system via
* Download Mode works -> TWRP install -> Mount option -> use ADB to recreate EFS partition -> re-flash stock image (android 8) with odin
- device works fine
- then i've noticed it can only be used with a certain cell provider (o2)
- then i've tried to flash an older version of the stock rom (android 7) due some problems in Android 8 (often some slow downs while operating)
- this doesn't work, the flash don't start
- therefore nothing should be happend, or?
- then i've can't get anymore in the stock recovery to wipe all data
...therefore the mess began:
* i can't flash TWRP anymore
* i can't flash stock recovery anymore
* i only can get into download mode
* i can only flash a certain rom type successfully (green PASS within odin), but with the final stuck with boot loop, with the mentioned blue screen
* other rom version can't flashed
I hopefully ask you guys here, if anyone can help me?
Any help would be very appreciated ...
