Encryption lock screen, not booting after password || E: failed to clear bcb massage

Hi Everyone,

My phone asked for update then after update was complete it got turned on and it booted up to the encryption lock screen where it says to start up your device, enter your pin. So I enter my pin and then its says, "verified" and then "starting android". and then a padlock appears on the screen, it opens, and there's like a load up circle going around it. At first, I let the phone sit to see if it would do anything but after an hour, I figured something is wrong. I dont know why this happened. I don't want to have to factory reset and lose all my pictures and data. I can boot into recovery mode but sometimes when i turn it on it shows a screen that says installing update and has like a google ring looking thing that should be spinning around but it looks like its glitching out, after that screen it will go to a no command screen, and then it will eventually reach recovery mode but all I can see is:

#fail to open recovery_cause(no such file or directory)#
#Reboot Recovery Cause is [UNKNOWN]#
No Support SINGLE-SKU
File-Based OTA
Supported API: 3

# MANUAL MODE v1.0.0#
Successfully verified dmverity hash tree
E:Failed to clear BCB Message: failed to find / misc partition.

I have tried safty mode, but this also didn't helped. I really hope someone can help or knows what is going on because, I really dont want to lose all my pictures. 

Thanks you.
Veronica

Hi Veronica,

 

I had the same problem and just solved it.

I'm on o2 UK S7 Edge and as it was upgrading it hung and wouldn't start.

I had about 70% battery at the time, i fiddled with it for 2 hours and it finally started working properly with the rest of the install as I plugged it in (and it said i had 0% battery, which i think the phone is confused about.)

 

Try plugging it in. Also try to go to Android boot menu (holding power up, power and home key at the same time for a while restarting), from there power off, then power on again.

 

I had it stuck on the white Samsung lettering on black screen for ages. Then when i plugged it in, it finally continued setup and now i'm oreo!

 

Good luck,

 

Daniel

 Hi Daniel,

 

I'm on EE UK S7 Edge. I have tried this method twice now, left phone for about 10 hours but still nothing moving forward. Do you know anyway of recovering data from a bricked phone? 

 

Thank you,

 

Veronica

Hi Veronica,

 

So I believe it's nothin to do with Samsung. Android is made by Google and given to carriers (EE, Vodafone, O2) who then play with it, add things to make it their own, test it and when they're happyy with it release it to us to install. As this seems to be affecting people with different carriers (i'm o2, you're EE) this might be an android issue (google not samsung).

 

In any case... what i did was i was able to get into boot menu and one by one i tried the options to see if i could make it work (my phone is 2.5 years old so out of warranty i assume, plus i'm enough of a hacker to figure it out myself and not give my phone to anyone for a month to fix it). Nothing was working, so i tried the option to factory reset it (knowing i'd lose everything on my phone), i knew that i didn't have much to lose as i've recently backed everything up to my laptop so only had a few bits to lose. This reset still didnt make it work. It only came to life after i plugged it in, went back to boot menu and chose to power it off.

 

then i started it again with just power button and left it on the White samsung logo on black screen (which was stuck there for ages before, and after about 10 mins i finally saw it was doing something). it still took a long while for it to finally install Oreo and it reinstalled all my apps (i had to remember passwords that i used years ago which was fun) and took hours to redownload everything and its not far off where i had my phone. i only lost a few photos, videos and some music - most of which i can get back. By signing back to samsung and google on the phone, it brought back my texts, contacts, bookmarks etc, but only back to mid March, last time it did some backup (it did it itself).

 

Question is what have you got on it that you'll lose and what has it automatically backed up without your knowledge to google and samsung (cuz it does backups automatically most likely).

Another question is whether you've done the factory reset in the boot menu as i had done?

 

From the stage of it not working at all, i doubt there's a way to access it unless you had things backed up on memory card, in which case you just stick it in another phone or computer. but if you had it on the phone memory, you need to patiently play with it until it comes to life. I'm happy to help as much as i know. If mine came to life somehow, good odds yours will too.

 

SO tell me more about what you've done to it (accessed boot menu?) where is it stuck? Do you know how to make it restart? where does it hang, etc...

 

Cheers,


Daniel
