Iphone 4 stuck when trying to unlock with SIM PIN code

The phone works normally except for the SIM. I can unlock it, then open apps, preferences etc. I’ve made a backup in iTunes, then reset the phone to factory settings, then restored the backup. This didn’t fix the problem.

When I enter the SIM PIN code, the screen is fixed at “unlocking”, while showing the number pad. I can’t go back to the home screen. I can shut down the phone, restart it, everything is back to normal except for the SIM. I see that I still have three tries for the SIM. I’ve tried to enter a false PIN to see what happens, but then it’s the same.

Is this a problem with the SIM or with the phone? Any ideas how I can fix this problem?

Can’t access main camera (stuck in wide angle)

My Zenfone 4 Max camera app is stuck on the wide angle camera. The icon on the picture below says it’s the main camera, but it’s possible to see by the curve on my wall that it’s indeed in wide angle. When I click on the wide angle icon, system says it’s now on wide angle, but the image doesn’t change.

I have tried restarting in safe mode, clearing app’s cache, restarting normally and tried using 3rd party camera apps. No success so far.

Any way to fix this without having to take it to Asus tech support (they take forever to answer) and/or restoring factory settings?

RHEL KVM stuck when trying to create VM under VMware Fusion

I am trying to use KVM on RHEL 7 VM but after I try to create a new VM it goes well until I click Finish button, at that moment the window stuck and does not respond anymore, so I can’t create a VM!

That’s what I used: – VMware Fusion Professional Version 11.0.0 (10120384) – RHEL 7 + KVM – Mac book pro with Mojave – I enabled the VTx feature on VMware Fusion.

Here you can see a screenshot of the problem:

Any help will be appreciated, thanks.

Odin stuck at “File analysis”

When I press “Start” in Odin3 3.13, the log just says:

<ID:0/006> Added! <ID:0/006> Odin engine v(ID:3.1.1301) <ID:0/006> File analysis.. 

Then it is stuck forever, with the desktop computer’s CPU constantly at 30% and 0% disk usage.

The same happens regardless of whether I start Odin then connect my device in “Downloading” mode, or whether I connect my device first and then start Odin.

Question: How to solved the problem, and successfully download the patched firmware?

My configuration is: – AP: magisk_patched.tar produced by Magisk from the Samsung Galaxy S10e firmware AP_G970FXXU1ASD5_CL15820661_QB23234096_REV01_user_low_ship_meta_OS9.tar.md5 – Options: Disabled Auto Reboot, so that only F. Reset Time is left enabled.

Ubuntu 18.04.2 boot stuck on purple screen after updates

Summary of Issue
Last Friday, I installed updates to Ubuntu 18.04 with sudo apt-get update && sudo apt-get upgrade. Some of these updates required a restart. Upon restart, after GRUB, boot got stuck on a purple screen before the Ubuntu logo/login. I can’t access the terminal at this step through Ctrl + Alt + F7/T/F1/F2 methods. Recovery mode does not work, and gets stuck at Loading initial ramdisk...

Attempts to Resolve
As stated above, recovery mode did not work.

  1. Attempted to use Boot Repair, this ran successfully but did not resolve the problem. Output from this attempt here.

  2. Next, I backed up some files then attempted a fresh install of 18.04.2. This worked, but as soon as I grabbed the ~400 MB of updates for this clean install, I encountered the same problem as before. I tried using both the Software Updater, and terminal. I’ve got no idea what update is breaking, here’s a full log of updates run.

  3. Saw what may be a related issue here: Ubuntu freeze on boot purple screen. Seeing that this user seemed to have an issue with kernel updates, I excluded kernel updates from running and tried again, still the same result as before.

So at this point, I’m at a loss as to how to proceed. I’m hoping I can get some help on this thread. Otherwise, I may need to downgrade to 16.04 or upgrade to 19.04…

Ubuntu 18.10 stuck at initialising ramdisk after fresh install and subsequent update


  • Asus Zenbook 14 UX433FN (NVMe PCIe SSD)
  • Ubuntu 18.10 and Windows 10 dual boot, Windows 10 working fine.


Today my Ubuntu 18.10 suddenly gave me a “purple screen of death” after I closed my laptop lid (ie. it couldn’t wake up from suspend).

After which, I forced shutdown and tried to reboot (both normally and with recovery mode), and both times it got stuck at Loading initial ramdisk...

Quirky Behaviour

After this I successfully reinstalled Ubuntu 18.10 using CD. TWICE.

Each time, after successfully installing graphics drivers and everything, Ubuntu automatically prompts me to do security updates etc. Before installing updates, I can use and boot into Ubuntu normally.

BUT after installing these updates successfully, and rebooting, I get stuck at Loading initial ramdisk... again.

Resolution attempts

  1. Use LiveCD as per https://help.ubuntu.com/community/LiveCdRecovery#Update_Failure.
  2. Update kernels before installing.
  3. Replacing quiet splash with nomodeset.

Why is this so? Is there a bug in the update repositories somewhere?

I can use Ubuntu without updating of course, but this leaves my computer vulnerable to security issues. In the long-run, being afraid of updating the computer lest I get this same error is quite stupid.

Boot stuck on „[ OK ] Started GNOME Display Manager.“

So since I started 2 days ago with ubuntu and Linux and have no experience whatsoever, I thought that I could just easily update my AMD graphics drivers. I installed some driver, but I think it wasn‘t the right one, since at a reboot, my PC stuck at the screen with the message above… Is there a way to fix that? It has to do with the AMD drivers I think.

stuck on“Downloading… Do not turn off target!” when trying to boot via adb

I wish to flash a custom ROM on my galaxy tab a. To do this I downloaded ADB and twrp-3.2.3-0. when U run the command adb reboot bootloader my tab gets stuck on downloading... do not turn off target. I know how to get out of this screen (power + vol- + home), but how can I get past this screen so that I can flash twrp?

Updated laptop from 16.10 to 18.04 LTS, Stuck at /dev/… clean, ***/*** files, ***/*** blocks

Haven’t touched this laptop in a while, so when I did, I updated it to the most recent LTS.

It is a dual-booting Windows 10/Ubuntu system.

I get stuck at /dev/nvme0n1p7: clean, 291381/1324512 files, 3883511/5297920 blocks. after selecting Ubuntu in GRUB.

I saw some other users fix by purging nvidia drivers, which my system does not have (no nvidia GPU, tried it anyway, just listed 0 installed, 0 removed etc.)

Saw some others suggest sudo apt update, to which I got these:

Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/bionic/InRelease Could not resolve 'au.archive.ubuntu.com' and similar 5 other lines, with the last one being cannot resolve 'dl.google.com'.

Does anyone know what I can do to get back into my system?
