Hi guys .. so i downloaded a custom theme from here ( dna aos-p black ) .and it worked however when i restarted my phone it was all messed up so i went to reapply it and then my phone restarted and now is stuck in boot loop.. it shows flashing Samsung logo and then optimizing apps and the turns off and repeats..
Phone is on android 8 with may security patch ... PLEASE HELP.. And thanks..
if memory serves you need to:
- while the phone is booting - once the Samsung logo starts appearing, press and hold "volume down + power button"
if it doesn't reboot then try playing around with your timing - when to start pressing both buttons.
if you get the timing right the phone should reboot into download mode form where you can flash the latest stock ROM

I've gotten myself into many a boot loop while flashing ROM's that didn't "sit well" with my SM-G9500.

So I am on a stock GT9500, suddenly today the phone restarts, gets stuck on the Samsung logo and keeps going into a loop till the Samsung logo.
Also, as soon I remove and insert the battery, the loop starts. I dont have to press the power button for it to start.
The battery was about 70% if I recall correctly. It wont go into recovery and I am unable to try download mode with odin as I am in Office.
Any help please?
Your only option is Odin given you have no recovery.
Hello
So today was planning to flash with a new ROM, so i started to do a factory reset from with in android, nothing happened
so i reboot the phone to enter recovery mode to do it from there, using Teamwin for that. But when booting up, getting the message entering recovery mode 5 sec later i see the logo for Teamwin and here it stops.
The logo keeps flashing every 4 seconds or so. Have tried without Sim card, done the battery thing where i remove
it and hold the power button for a while, but all end up in same, the teamwin logo flashing
As far as i can see i can´t enter anywhere to flash the phone as the only thing i get is a flashing logo...
Also Odin does not detect the phone via usb either
is there a way to resolve this?
Thanks
Phone Model: AT&T LG G2 (D800)
Recovery: Custom TWRP Recovery
ROM: CM12 Official ROM
My phone was working fine from last 3-4 months, until today it restarted and got stuck on 'LG' logo, I left it for some time and it shows the demigod green screen of death with option to access download mode and restart.
What I already did!
1) Full hard reset, I can access the TWRP.
2) Flashed the ROM again.
Current Situation!
Stuck on LG logo from last 10mins.
Thanks in advance.
Edit #1: Reflashed the same ROM (CM12) and it booted into the language selection page, freezes and restarted. Stuck on black screen, I turned it off by pressing the power button for 10-15 secs. I kept it in a freezer for 10-15secs and turned it on, same happened.
Edit #2 I flashed a stock based ROM through TWRP, it was going fine but it froze in between, I waited for some time and it went black. I waited for 1 hr and it was still black so I hold the power button and restarted the phone.
Now its showing "Secure Boot Error" which remains for some secs and a black screen comes, I can't open TWRP, Download mode is accessible but after 2 secs into download mode, secure boot error comes. Whenever I try to connect it to Windows PC(I installed all the required drivers and all) it starting popping up drives(with option to format) which never stops until I remove the USB cable.

Steps to perform.
1. While in critical error screen you have an option to press volume up button to boot into download mode( although it will not boot to download mode) but still press volume up button so your Pc can detect your phone.
2. Now flash a kdz file of your lg g2 with flash tool. ( you can google for it to download flash file for your lg g2 and how to flash it with lg flass tool.)
3. When you will try to flash it will fail..
4. Now power off your phone by pressing power button.
5. Now boot to download mode and flash the correct kdz with lg flash tool and u r good to go..
To acess download mode power off your phone immediately press volume up button and while keep pressing it and plug in usb cable and you will be in download mode
I performed all this on lg g2 d801 but i hope u can try it on other varients as well. As i was scared of short circut method and srk tool didn't help..

Thanks for replying.
My case is a bit different now, I reflashed the same ROM(CM12) and it successfully booted, worked for 10 secs and it was frozen, restarted automatically, stuck on LG Logo.
I notice that there's some heat issue, I kept it in freezer for 10 secs, rebooted it, it booted till language selection page and freeze after 10-15secs.
Also the link is for DemiGod Critical Crash, mine is DemiGod Kernel Crash.
Updated!!
First post updated, please check the current situation before posting anything.
I don't have a computer or laptop to connect it to so how can I fix it?
hi all,
Just come back from holiday and SM-G928F edge plus (european model) battery was completely flat.
I charged the mobile and booted it up, loaded into Android then sounded like a lots of notification alerts then phone made a loud buzzing noise and crashed/auto-reloaded.
Since then it had gone into a boot loop. Tried holding power and vol down to reboot phone. Initially this function worked then no longer worked. Phone still stuck in boot loop...
Could not get into safe mode (hold power and vol down then release power)
Tried in recover mode (hold power, vol up and home), tried clearing cache took ages about 1 hour, also tried the format option, rebooted system and still boot loop..
Tried going into Odin mode (power, vol down and home) , used ODIN s/w and installed the latest XER version firmware, got success message but still boot loop...
Interestingly when I left it to constant boot loop, eventually it booted up Android now. However once I start using the mobile it intermittently reboots the mobile and then goes back into boot loop again...
When I did manage to get into Android I tried using an app to check the mobile health, strangely I notice it said I only had 1gb ram spare and the rest was used when mobile was factory reseted and I didnt expect so much RAM in use. During stress test mobile crashed and gone into boot loop again...
I am not sure this was affected by an auto update that may had gone wrong.
I don't root, just used stock firmware.
UPDATE:
Left mobile in boot loop until battery went flat, fully charged it and now can get back into Android. But it started to auto update some app and then auto rebooted/crashed and went into boot loop again.
Please help.
Thanks
Is there anyone who can help me please?
I thought of testing out different custom ROMS available for my device (Samsung A20 ) just to see what fits me, So I tried to flash a custom ROM "Havoc OS", right after flashing a ROM from XDA under my phone's section which is another custom ROM which i guess is ported from S20 " https://forum.xda-developers.com/galaxy-a20/development/ultimate-q-s20-v2-rom-t4104667 " and installed the ROM it worked fine, but after flashing Havoc OS, It boots up but the screen goes black after few seconds after displaying the Samsung logo... Knox... Powered by android and all that but goes off quickly and the black screen starts to appear, i tried holding down the power button and volume down together and also power button + volume up but nothing seems to work, i.e it won't get me into recovery or download mode. I tried using Odin while the phone is connected but even then it didn't show up on Odin's log as well. Please help :crying:
Update: The problem was fixed: I left the device to stay in the boot loop and the battery drained and then when I connected it to the power brick when the battery is completely drained i was able to boot into twrp recovery without a problem. ( Also i did this after removing the memory card )
