I can’t boot to Flash Drive containing Ubuntu

I’ve used Rufus to create a bootable pen-drive with Ubuntu 19’s ISO. Then going into BIOS and selecting USB to boot first (Not UEFI option of the same), then I received this error: https://imgur.com/s4Rzb9I

I contacted a Discord server for help. Its administrator said me to try 18.04 version instead. I did the same process with Rufus, now following this tutorial: https://tutorials.ubuntu.com/tutorial/tutorial-create-a-usb-stick-on-windows#0.

Then booting by the same way I received this error: https://imgur.com/etezYw5

After this I’ve tried to put this same USB with Ubuntu 18.04 in another computer, which I don’t have the specs to show, only saying that the specs are lower than my actual computer. In that another computer, the error was this one: https://imgur.com/FKjqKgc.

I’ve hashchecked the ISO in the two cases, all hashs was the same as official provided by Ubuntu’s website.

Playing a sound depending on the currently displayed flash card image

I’ve developed a fully working flash card app for kids. It has a UIImageView that cycles through 26 cards (abcs) via a gesture click and a music button that will play a sound for each image. Right now I have this 100% working, but the sound plays in an IF statement that has added an additional 400 lines of code.

How I load each card into the UIImageView from a gesture tap:

        // if the tapped view is a UIImageView then set it to imageview         if (gesture.view as? UIImageView) != nil {             if segControl.selectedSegmentIndex == 0 && segControl2.selectedSegmentIndex == 0 {                 imageView.image = UIImage(named: "card\(number)")                 number = number % 26 + 1             }             else if segControl.selectedSegmentIndex == 0 && segControl2.selectedSegmentIndex == 1 {                 imageView.image = UIImage(named: "upper\(number)")                 number = number % 26 + 1             } 

Music button:

    if (imageView.image?.isEqual(UIImage(named: "card1")))! {         do { audioPlayer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: aSound))             audioPlayer.play()         } catch {             print("Couldn't load sound file")         }     }     else if (imageView.image?.isEqual(UIImage(named: "card2")))! {         do { audioPlayer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: bSound))             audioPlayer.play()         } catch {             print("Couldn't load sound file")         }     }     else if (imageView.image?.isEqual(UIImage(named: "card3")))! {         do { audioPlayer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: cSound))             audioPlayer.play()         } catch {             print("Couldn't load sound file")         }     } 

I know i could set a sound array with the sound files in it, but how would i tie it back to the card? I cant set a tag property on an asset image can i?

Looking for a way to shorten the current code i have.

Can’t see partitions of usb flash drive in ubuntu 18.04

I was copying data to a Verbatim 16GB flash drive with NTFS partition format in Ubuntu 18.04. The copy ends successfully and I remove the drive properly. When I put it back in the flash didn’t mount. I open the disks aplication and it shows under the /dev/sdb with no other information and the only option allowed is edit mounting point. I run gmesg to check and this the message I got:

I appreciate any help to back my flash drive to live.

I Can’t Find My Physical Position of My Flash Memory But I Can Hear It

Peeps,

I don’t know if my USB is broken, but I do know that I can hear the usual notification sound when I plug it into whatever which port I decide. The problem is that I can’t find the memory, it’s invisible now. More info I can give you: I formatted it after it refused to assimilate files that I’ve tried to replace onto it. I’m confused: did I messed up my Kingston DT50 16GB flash memory drive with that formatting? Also I can’t find any drivers for it in the official site. What should I do?

See the picture. The first half is when I have it plugged – obviously PC recognized it, but it not appears to me.

It’d be very helpful if you tell me something.

Thanks!

Can I flash an unlocked G900T bootloader on a G900A?

I have a G900A and a G900T (short story: couldn’t live any longer with the locked bootloader on G900A so I bought a G900T to use on AT&T). It’s possible to flash a custom recovery/ROM onto the G900A, but it seems that the bootloader will recognize things as not being signed on boot and will not allow booting.

However, if I were to flash the G900T’s bootloader onto the G900A, I could potentially bypass this restriction. Since it’s basically the same hardware, it should theoretically work. Not wanting a hard brick, is my logic correct? What facility examines if the bootloader is signed? Will it allow me to flash an unsigned bootloader in Odin? Is the bootloader truly the source of the locked problem?

Server OS on an internal USB flash drive – is this standard practice today?

While chatting with a sysadmin colleague of mine about setting up a small server for me, I found out something interesting – most servers these days apparently contain an internal USB port which can be used for attaching a boot flash drive. On one hand this makes sense – the OS doesn’t need to use its disk much, and all the data is being kept on actual fast hotswap drives. We’ve successfully eliminated the need for an extra drive bay.

On the other hand – flash drives??? Really? Is this… safe? Seems so weird. Is this really common practice today?

SP Flash Tool does not recognize the firmware scatter file

I have a neffos X1 Lite and it seems that it boots only in the twrp recovery console.

Anyway I am trying to restore my official recovery console (i have no backup) using the official firmware http://www.neffos.com/en/support/download/X1-Lite

Inside this zipped file, there is a file scatter.txt that contains the following content.

preloader 0x0 pgpt 0x0 recovery 0x8000 para 0x1008000 expdb 0x1088000 frp 0x1a88000 ppl 0x1b88000 nvdata 0x1bc8000 metadata 0x3bc8000 protect1 0x5bc8000 protect2 0x63c8000 seccfg 0x7000000 proinfo 0x7040000 oemkeystore 0x7800000 md1img 0x8000000 md1dsp 0x9800000 md1arm7 0x9c00000 md3img 0x9f00000 nvram 0xa400000 lk 0xa900000 lk2 0xaa00000 boot 0xab00000 logo 0xbb00000 tee1 0xc300000 tee2 0xc800000 secro 0xcd00000 keystore 0xd300000 system 0xe000000 cache 0xeb800000 userdata 0x106800000 flashinfo 0xFFFF0080 sgpt 0xFFFF0000 

Now, using SP_Flash_Tool-5.1916_Win to load this scatter file I get an error “Invalid format”. So, how am I supposed to un-brick my phone? I still have access to ADB, Fastboot and no matter what I can not boot to OS.
