Hello guys.
I do have an SGS4 i9505 which runs on CM for more than two years now.
In February 2015, I've installed TWRP 2.8.1.0 then CM12 and the associated GAPPS.
Today, May 20th, I did the update to CM12.1-20150519 from the updater of my phone (Settings, About..., CyanogenMod).
Unfortunately, since then, my phone does not want to boot anymore. It keeps boot looping. I can see the (nice) "Samsung Galaxy S4 i9505" screen but nothing more.
I can access the Download Mode but only for a couple seconds, then the phone shuts down.
I can press the VolDown + Power button to try to access my recovery (TWRP 2.8.1.0 as I previous mentioned), I do thee the same "Samsung Galaxy S4 i9505" screen bith the "recovery access" in blue in the top left corner of the screen, but that's all.
Have you guys any idea how I could skip this loop and proper reinstall ? Is my phone hard bricked ?
Thanks in advance,
Daga.

Hello, and welcome to XDA! It is possible that you needed to update your bootloader as well as the rom, hence the bootloop. You can get help by asking your question in this help thread: http://forum.xda-developers.com/galaxy-s4/help
If you can access your bootloader, your phone is not lost at all. You can flash factory firmware, or perhaps simply flash the latest bootloader, or the recovery back. There is plenty of information on how to do this here: http://forum.xda-developers.com/showthread.php?t=2265477
Good luck!
Yesterday i rooted my LG G Pad 8.0 but right after that it started bootlooping.
I don't have cwm, it's just rooted (can't check it as i can't load android)
I have rooted a lot of android devices but this is the first time it happens to me (without cwm). When i try to hard reset using the
hard keys combination it starts, it shows the android logo for like 1.5 sec. and it just reboots.
It keeps rebooting when i power it off.
Hi, thank you for using XDA Assist.
What you need is a format and possibly a reinstall of your OS. This Thread has all you need.
Okay so i replaced the screen on my mega. was running stock rom no root. now i put the new screen on go to do test and im in boot loop. now i take and put the old screen on to see because i wasnt in boot loop prior to this. now this screen is also showing boot loop. now i cant access recovery it will show logo screen with blue recovery booting and then just keeps looping. now i have flashed several firmware from sammobile with no success. i have also flashed cwm recovery and i can get the android guy with a download bar but it stops with him falling over and a red triangle above him. no recovery then back into boot loop. i cant access recoveries period but i can get into downlaod mode whenever i want. as this point im not even sure what to try to try. does anyone have any suggestions or ideas of anything that will work.

Just wanting some advice (if any) to a white line issue I'm having with this tablet. I bought this tablet with Lollipop 5.0.1 already installed. I managed to get it downgraded, rooted, and currently have TWRP installed as well as CM12.1 nightly. The problem I have is that as soon as I install ANY custom recovery (TWRP or CWM recovery) it boots normally at first giving me the LG logo. Then, instead of getting the AT&T logo (or the CM custom boot animation), it gives me a series of white lines spamming from top to bottom of the screen. I know for a fact it has to be software related as when I return to stock KK everything boots fine, giving me the LG logo followed by the AT&T logo. I did NOT use the ADB method. Instead I downgraded using the LG Flash Tool, and a test KDZ file, which allowed me to install Flashify, then TWRP. My problem ONLY begins once I install ANY custom recovery. This process did not unlock my bootloader, however. Could this be my culprit, or would it be something else? Any help is greatly appreciated, and thanks in advance for any help/tips. More information is completely available upon request.
P.S. The white lines eventually disappear when the screen goes to sleep on it's own. I can then press the power button to wake the device which gives me the lock screen as normal. I just want to know if I can get the boot animation working. Everything else works fine.
You found cwm?
I have a Acer E380 phone that is still on JB. So I tried to update it to Kitkat 4.4.2 but when I flashed it, it gave me an error about something in the scatter file. so I just removed my phone afterwards and just tried to open it thinking that the installation did nothing. Now my phone just constantly vibrates every 20 seconds or so but the screen is black. Can't boot into recovery or anything. it just vibrated like its going to boot up. I seriously need help please!
