[Q] Phone no longer booting after new SIM inserted - Samsung Galaxy Nexus

I bought a new phone plan in Europe. I am trying to transfer my old number. I had the new SIM in the phone, and it didn't respond to the old number. I booted off the phone, inserted the old SIM, and booted the phone. The touch screen got stuck at the SIM unlock screen (Where I input my password for the SIM). It was completely unresponsive. I took out the battery. Since then the phone won't boot. I get the google logo with the unlocked image and then it just goes black. I can boot into recovery, but I don't know how to find what's wrong. I haven't backed up my phone in a couple weeks, so I'd prefer not to restore, but that might be necessary I guess. Does anybody have any ideas? It was working fine before this happened.
I'm running the Vanir Mod and Kernel on the Samsung Galaxy Nexus.
Update: I just tried to reboot the phone from recovery, it asked me if i wanted to fix root permissions. I slid the bar for yes. Now I can't even boot into recovery anymore!
By the way, it doesn't make a difference if I have my old or new SIM card in.
Update: I cannot access the phone when connected via USB. In the device manager I see Galaxy Nexus under portable devices with the exclamation mark on the yellow triangle.

[Q] bricked or screen problem?

Last night i sat my phone down for a minute i sent a text and when i came back it had a weird screen on it. I tried taking the battery out and rebooting it but it took me right back to the same screen I entered recovery after my 3rd fail of getting it to come back on it showed the recovery screen but i had to press the buttons alot to make it switch options and even then it froze on me i was trying to back up my SD by mounting it then restore a back up but cwm so after a few failed attempts i used flashtool to restore the stock firmware hoping that this would fix it. It failed i tried it a few times but no changes.
The reason why i don't think it's fully bricked is because it shows the screen in the pic but when i press by where the unlock slider is my phone vibrates and when i slide it to the right and do my pattern over the screen i can change the volume and when i turn it all the way down it does vibrate and i still get notification sounds.
My MMI code stopped working a few weeks ago i dont know if this is what would cause this because i do know ics is coming for xperia devices but since my MMI code stopped working i was no longer able to get to the service menu through the dialer i tried *#*#SERVICE*#*# and looked at youtube videos that said add commas and stuff and that made theirs work but it did not work on mine.
i tried taking the SIM card and sd card out and turned it on it did not work so it has to be something wrong within the phone itself
My cwm is now gone since i flashed the new firmware and i don't know how to get it on because the cwm for locked bootloaders requires the debugging setting on which i can not get to now. So please give me advice on how to fix it! if all fails i will just take it in to the ATT store my phone is the r800at ftw
Bricked means the phone will not turn on. Ever. That's a LCD problem.

Black Screen after Rom Flash with Odin

Where to start... So I Flashed a stock rom "M919UVUAMDL_M919TMBAMDL_M919UVUAMDL_HOME.tar" with Odin to my M919 3 times with the same result.
Used Odin 307 with PDA and only Auto Reboot checked each time. Flash went fine completed successfully with Pass each time. Unfortunately that's where the
success ended. The phone rebooted with the TMobile Logo and Samsung logos flashing on screen and immediately went "Samsung is Upgrading 155 applications."
After this process it rebooted once again Flashing the TMobile and Samsung logos. Once booted, the phone screen is black with no icons. At the very top of the
screen, I have a battery icon, the time, 4 bars despite having no sim card in and that little eye icon. At the bottom, the back and menu buttons light up when
touched. The phone is recognized by windows and does allow me to browse the file folders. On the off chance that my file was corrupted somehow, I downloaded it
from a second source the 2nd and 3rd times I flashed it. Now I'm stuck. Nothing I do changes this condition.
Please Help!
** After several attempts I managed to get the phone into recovery mode. Unfortunately the phone Is still having issues. The TouchWiz is back and all the icons, it goes through the setup process but it's unable to turn wifi on and it doesn't seem to see my sim card. Aside from a hardware failure of some type, I don't know what this could be.

Have you tried going into recovery and doing a "Factory Reset" and reboot, it might fix the problem.
Also if it does not fix all the problems you can try to boot the phone up just to get into the SETTINGS
screen, then goto settings>accounts tab>backup and reset> and select "Factory data reset" then
reboot the phone if it does not reboot on it's own.
Good luck!

Pixel 3 XL bootloop when on T-Mobile network. Now it won't boot up. Please help!

I have a Pixel 3 XL using it with T-Mobile. Today, all of a sudden, the phone went into a bootloop. It will eventually boot into recovery.
If I make it boot (Try again), it will boot up briefly. I see the upper left corner flashing between "No Service" and "T-Mobile" quickly. And then in a few seconds, the phone will reboot.
If I pop out the SIM card. The phone will boot up fine. Everything is in there. If I put in a non-T-Mobile SIM, say Tracfone, it will also work fine. But as soon as I pop in a T-Mobile SIM, any T-Mobile SIM. Doesn't matter if when it is in boot menu or when phone is up. It will reboot.
Here is how I really screwed up.
I thought it is an issue with my T-Mobile SIM being too old. I went to T-Mobile and converted my SIM to an eSIM. And then I loaded the QR code onto my 3 XL. Everything seems okay at first. But boom, the phone starts rebooting.
Even worst, now I cannot use my phone at all. Regardless if there is SIM in the slot or not. Does not matter what vendor. I even managed to put the phone in Airplane mode. SAME RESULT. Phone will boot up and reboot right away. I lost access to my phone completely. My only other option is factory reset and lose all my data. Even that I don't know if it will work.
Any ideas how I can recover from this?
Is there a way to erase the eSIM?

I need some help with fixing a Samsung Galaxy S3 (SPH-710T, Sprint) that cannot boot to custom ROM

Hello All,
I recently found a Sprint Samsung Galaxy S3 (SPH-710T) that cannot boot to its custom ROM, CyanogenMod. The only thing I vaguely remember is a few years back when a coworker of mine had pulled out the battery when the phone was either rebooting or installing an update. The phone still boots to download mode, but when I do the combonation for recovery mode (Volume Up, Power, and Home), it shows the startup logo and blue text at the upper right corner, but then immediately shuts off. I have tries using download mode to install TWRP, but every time I do it, the program on my computer says that the process was successful, but the phone shows no sign of the program being installed. I have also been successful when downloading CF-Root to the phone, but the attempts at installing TWRP after that yeild the same result. I saw a video detailing a de-bricking SD card, but got scared after I learned that the card were not interchangeable between models. I am here for any questions you might ask and I will happily try any of the solutions provided by people.
Thanks so much for all of your help,
Max
