[Q] Phone will not boot - Galaxy S II Q&A, Help & Troubleshooting

Hey all,
My Galaxy S2 won't turn on, I have tried a soft and hard reset, I have tried to boot into recovery and into download mode, I have removed the battery for 30 mins and tried again, I have tried another battery. The phone seems to be on as the battery/top of the phone is still warm, any ideas?

What did you do before this state? Flashed a rom?

have you tried a jig to put in download mode?
when you connect to pc what is the uotcome? maybe you can boot to recovery via ADB?
but try a jig first

i wiped data, nothing
i flashed cwm with odin, (CF-Root-SGS2_XW_OXA_KK5-v5.0-CWM5.zip) wouldnt mount sd. went and choose fix permissions, able to mount sd, reset, nothing
flashed stock, still stuck
flashed bootloader and parafram, now stock recovery wont show up
still can go download mode, still can recover mode when i reflash cwm
any help? can it be fixed?
Download mode is always a good sign. These steps are going to bring you back to the day you bought it:

does this require the usb jig? can it be flashed without it?
and the stock android recovery is not working, it just displays "deleting encryption meta data" then turns off again
No jig needed if you can still enter download mode.
Take the battery out. Put back in, plug USB cable in while holding volume down.

[Q] samsung s3 boot loop, will not connect to PC

Hello People
Im in need of your help please!
The other night my battery went dead on my Samsung galaxy S3, after charging it fully, i tried to turn in on. However it was stuck in boot loop
So far i have tried everything, Ive tried
factory reset
clearing cache
putting it in download mode
taking the power button out
I downloaded kies and Odin to try and put the new firmware on, however my phone will only charge through the USB port and keeps saying windows does not reconigse the device as it is malfunctioned. I have installed all the drivers, tried computer at work, tried a different lead, but nothing!
Can anyone help me, are you able to put the firmware on through SD card as there is no way of me getting into the phone!
Thanks in advance!

TWRP recover boot looping - unable to go into recovery

Hi guys, I flashed cm-13.0-20160820-SNAPSHOT-ZNH5YAO0J2-i9300.zip and everything worked fine BUT I did a factory reset from the system itself not from the recovery and since then my phone is stuck between samsung logo and twrp logo which appears only for a second or two and then back at samsung logo....I cant enter download or recovery mode, I cant turn my phone off, every time I put battery in it, it keeps looping. But I have noticed that when i connect it to my PC it just loops in samsung logo not between twrp and samsung. Help me please ASAP :crying::crying:
Do you have a USB jig to force download mode?
I dont have USB jig, is there any other options? My phone can get to that download mode by pressing buttons and it shows only for a second screen of download mode and then it goes back at looping....
Could be a power button problem?
Well I really dont know because I had removed the button before, it didnt work correctly and now I cant know is it up to button or the software ....

Samsung j6 soft brick problem

Hi guys, I have a samsung galaxy j600fn/ds, tryed to flash twrp, something went wrong and now I'm locked on the ''Samsung'' logo screen
I guess it is brick, though I'm totally stuck at the screen, the phone won't even turn off, so I don't know how to acces download mode to install stock firmware.. anyone can be of help?
EDIT: solved.. of course the solution was just to wait for the battery to be completley depleted, I just got scared there not beeing able to do anything
Wait-
So you just let your phone in bootloop all night (?), then you charge it without turning it on,
waited till 30%, and then you put it in download mode and installed the firmwere?
Does it really work? 'cause I tried to do that before, and the bootloop stopped. I tought I ended up into an hard brick.
I pressed powen and tried to put the phone into download mode, but nothing.
I put the usb on my pc, and odin was actually reading it, so I tried again and again to get into the download mode.
Afret 30 minutes, i pressed power again, (and finally) the boorloop restarted.
Well um.. the phone now is probably at 60%.. I hope it wont stop again, and I hope this method will work.
