Device disappearing

After installing the "15 seconds adb installer", I shift clicked the folder with my twrp file, "twrp-3.0.2-0-tbltetmo.img" to open the command prompt and type in "adb reboot bootloader" , causing my screen to go into boot loader mode. [ e.g. image ] ]So far, everything is going well, according to this guide.. However, the problem is the next step. Once in boot loader mode, i type in "fastboot flash recovery twrp-3.0.2-0-tbltetmo.img" . Instead of masses of text appearing, I instead receive the message: "Waiting for device." To be honest, I think my problem lies in the fact that before i went into boot loader mode, my phone was detected by my pc, but after it shifts to boot loader mode, it stops being detected, this causing the "waiting for device" message. However, even though I know the cause, I can't find any means to fix it after searching for hours. Also, yes, I enabled allow unknown sources and usb debugging. I've also went to T-Mobile's website to install their usb driver.

Disappearing Recovery?

Hello everyone, yesterday I purchased an LG g4 rooted and unlocked it but, when i'm attempting to reboot into recovery via hardware buttons all that happens is a white screen flashes it goes away and i see an android with a red triangle. I believe that means i'm on stock but, if I were to flash a recovery again and get to the recovery by adb command: adb reboot recovery it goes to twrp. Is this a common problem? Am i doing something wrong? I flashed https://dl.twrp.me/h811/ the 3.0 image.

Thanks guys!:cyclops:

Some apps disappearing after reboot

I have an android Marshmallow device. I put a 32 GB memory card in my device. I split it to 2 partition so i could use one as internal storage and the other as external.

I used the following command to split the SD Card:

sm partition disk:179:128 mixed 50

After that, I installed many apps. When i reboot the device, the apps that are stored in the SD card are removed. I don't know why?

Wierd New Issue - Photos Disappearing

So this has only happened twice so far (yesterday and today). But I took a photo, then I went to upload it to Facebook and it wasn't showing in the Samsung Gallery. So I went back to the Camera, and it was showing in the little preview photo in the bottom right corner, but if I clicked on that it would take me to the previous photo I took. Then if I reopened the camera, that photo didn't show up anymore in the preview pain.

The only thing I've done recently is put in a new 128 gig microsd card. Could the card be bad? or could this be a fluke (I did just reboot) so will see if it happens again.

Calendar notifications disappearing after 1 hour

Hi guys,

I am facing a strange issue since I installed the latest update on my S7. The notifications for S Planner events, that are shown when you pull down the top menu disappear after 1 hour. It used to stay there until I cleared them out manually.
I also tried Business Calendar 2 pro. Same thing happens there.
This is very annoying as I leave the notifications there until I deal with them and if they disappear I just forget that I was supposed to take care of something.
I was trying to find the setting that is controlling this with no luck. I really hope that this is a matter of setting or a bug.

Could someone help me with this please?

Thank you.
