android bootloop - Android Q&A, Help & Troubleshooting

Hi I have Jiake S6 Android 4.4.2. I have rooted my device and downloaded some audio enhancing app and it asked me to reboot. I rebooted and got stuck into a bootloop. Tried factory reset and cache clear in recovery mode but it didn't help. Also tried fix it with SP flash tool but it doesn't work so I'm out of options (I don't have CWM installed)

[Q] [Help] Cyanogenmod stuck in boot loop

I have a T-Mobile Samsung Galaxy S2 SGH-T989 and tried to install cyanogenmod 10.2, but I can't start it, it gets stuck in the cyanogenmod splash screen and doesn't get any further.
Here's what I did originally: I flashed clockworkmod (via Odin) and booted into recovery. I then installed the cyanogenmod zip file that I had copied onto the sdcard.
When it failed to boot, I tried several things: I flashed TWRP (via Odin) and then did a factory reset and system wipe, installed cyanogenmod (from TWRP) and did the factory reset again. Same problem, the system will get stuck in the boot loop. I also tried an earlier version of cyanogenmod, same problem.
I am quite sure that I downloaded all the right files for my device. I searched online and saw other people who had that problem, and solved it by wiping the cache/data after the install. This didn't work for me.
I don't know what else to try, so please reply if you have any ideas!
Thanks :fingers-crossed:
Not sure bout it but flash only the cm kernel via cwm then reboot to recovery again n factory reset then install the Rom all the best

if you have custom rom or stock rom coocked the kies cant help you.
do these solutions in order :
>>>solution 1 : in recovery do facotry reset and install rom , wip cache and dalvick. the first boot take time. so wait. if not worck try to format system before flashing rom.
>>>solution 2 : factory reset in recovery then install stock firemware by odin after flash is complete enter to recovery and do factory reset again. the first boot take time. so wait.
>>>solution 3 (danger, do it only if you give up if you dont have any other solution) : flash stock firmeware with odin but cheek nand erase all in odin, after flash is complete enter to recovery and do factory reset(compulsory).the first boot take time. so wait.
use latest odin version.
good luck.

i9300 samsung logo loop after each flashing

Hi everybody, I have a serious problem with flashing my i9300. I tried flash stock rom 4.1.2 by several methods (Kies, Odin 3.07) but nothing worked. Each flashing procedure runs corectly, but after reboot occurs samsung logo loop unless I remove the batery. I can get into download mode or recowery mode, I tried wipe reset, wipe cache, wipe dalvik cache but nothing is worked. Thx for response guys.
Try 4.3 stock rom. I flashed via Odin and factory reset via recovery mode, and it works!
Thx It works.
Get the stock ROM from:
http://samsung-updates.com/device/?id=GT-I9300
Yes...it's work.
Thank you very much.

Boot loop and TWRP message: "os not installed" on s9+

I have an s9+ i flashed it to a costume rom (TWRP) and then rooted WITH NO BACKUP it worked perfectly with no issues, best Android experience I've had until a root app required reboot to apply changes once my s9 tries to reboot it became stuck in a boot loop and i booted up to TWRP and did a factory reset and wiped/formated all my data then tried to reboot, and TWRP shows a message: "os not installed" i proceeded anyways and it's still stuck.
I know how screwed up I am but I need a solution pls...

Not sure why you did a factory reset or wipe your phone but the easiest solution is to install stock samsung firmware with odin and start again.
What app did you install?
