Hey everyone,
I'm having a problem after trying to flash CM12.1 on a i8190l.
The instructions I basically followed are the ones mentioned here: novafusion.pl/tutorials/installation-guide-golden/ and I used the rom Lollipop 5.0.2 (CyanogenMod 12.0) 20150428 stable with the Odin app to install it.
All went well up to the point 12. Click on Wipe, then use slider on the bottom to let process begin.
At this point I received a FAILED message with an error message saying below that /data couldn't be mounted. After that, I rebooted the phone, and it started loading the first android screen apparently. After a few minutes, Android threw up an error saying that it couldn't encrypt the data and had to reboot. After that reboot, the system won't stop going over a loop boot that flashes TeamWin over and over again.
I can still get to the download mode, what is the recommended step to take from here? Is it possible to recover the OS? Do I have to worry about the battery running out, or does it charge up while on download mode/other mode?
Thanks for your help
my galaxy note 4 (sm-n910t) caught in bootloop . i dont know what caused it. the phone simply restarts upto first bootscreen, ie upto 'samsung galaxy note 4' and then vibrates and then restarts.this process continues upto battery is down or i pull out battery.the phone is not entering to recovery mode but enters to download mode.
i have tried installing stock rom from sammobiles but it won't help.i have also installed custom recovery twrp but that also won't help to enter to recovery mode,
i am trapped pls help..
You didn't mention how you tried to install the stock ROM . Did you use Odin?
I just fixed mine with the same issue. I was able to boot into recovery and download mode but mostly download mode without bootloop when I had the usb cable plugged in. I used ADB when I could to boot into download mode, but the buttons worked too. Trying to restart the phone only lopped after the Google screen.
I followed several guides here to flash stock with Odin and wipe cache etc but none solved my boot loop issue. almost gave up but there is a video on You Tube that said the battery warping in the cause of the boot loop. The battery, after/during quick charge, may heat up and change shape causing the issue. Today I installed my new battery purchased on amazon and no more issues.
Now I am on stock and have to find a good rom.
If you do decide to flash back to stock there are a lot of good guides. You may find yourself stuck on the T-mobile screen for 15 minutes when booting for the first time but that is ok. If you still boot loop after installing stock and wiping cache I would try the battery.

hi OP,
did you find any solution to your problem?
Hello all. I'm also pasting this in the T-mobile thread in case it can be of benefit to someone. This is advice to use as a very last resort if you are experiencing the recovery bootloop issue AND you don't have the emmc failure bug. I had the recovery reboot, sudden shutdown with no warning, etc. issue for the past two weeks. I tried everything on Google and Youtube to fix my problem with no success. I flashed multiple stock ROMS and recovery tars (stock and TWRP) via ODIN, but nothing worked. Oddly enough, I never received the emmc error that I have read about. Also, in the few times that my phone booted normally, I even loaded the Wakelock Power Manager app, set it to partial wakelock and my phone STILL continued to bootloop. As a last resort, I bought a new battery, but the reboot problems continued in Android 4.4.4 Kitkat, 6.0 Marshmallow, 7.1 Nougat and 8.1 Oreo ROMS. Well, here is what finally helped me to get my phone back operational. I had a backup ROM from a previous install and a TWRP flashable version of the same ROM on my SD card (in case the phone did not stay on for the full restore). I put the phone into a ziplock bag into a freezer for about 20 min. (thankfully this time TWRP stayed on long enough for me to do the following):
1) copy all the files I wanted to save from internal storage to a computer.
2) performed a full wipe (Dalvic, Cache, System, etc. Like when flashing a ROM, but this time also internal storage. Note: Please do not wipe both internal and SD card, as you may have a difficult time trying to load the ROM file back on the sd card (assuming you don't have a card reader).
3) After wiping, I was able to restore my stock ROM backup (or you can just flash the stock ROM).
I can't be 100% sure, but I think my wiping internal and then flashing the stock ROM finally did the trick. Since this morning, the phone has been pretty much back to as it was before. In either case, I'm sharing this with the hope that it helps someone else.

Thanks sir! I have the same issue! it's working now after replace the battery
So I tried to mod my phone (with this, if you're interested https://forum.xda-developers.com/gal...creen-t3759567) but I did something stupid. I thought TWRP was working properly but I'd installed Oreo and didn't wipe data. Well I installed the zip anyway. At the end, an error showed up (could not mount /data or something similar) and my phone will now not boot.
If I try to boot the phone, it just vibrates and stays black. Volume Down + Power + Bixby gets the phone out of this state and the charging screen shows again. I can't boot into TWRP at all. I can boot into download mode but Odin keeps failing when I try to reflash the XEF Oreo firmware (screenshot is in the attachment, it says passed but doesn't attempt to flash the files). I managed to flash TWRP which worked but since I can't boot into it it didn't help. Anthing else I can flash with Odin, or can anybody tell me what's going on / if it's unrecoverable? (I've tried a couple of different versions, they all exhibit the same behaviour)

There is a newer version of odin, are you using that? You will need that to flash Oreo. Can get it in the link below. Odin v3.13.1

Doh! Had it already, was the only one I didn't try. It's flashing now. Many thanks
So recently i bought note 5 N920T T-mobile variant and after few days i encounter a weird problem that i can't figure out what exactly is going on.
Once a sudden my phone freeze and touch screen stop responding then phone goes black screen and a strong white led light turn on while screen is black.
Then after pressing 3button together volume down+home+power the phone reboot normally
Then after few seconds again and again same thing happens.
I was on stock rooted 6.0.1 marshmallow rom with arter kernel permissive since i bought this device.
Things i tried
Factory reset from twrp (didn't change a thing)
I flashed stock rom marshmallow and nougat both via odin (got worse now more freezing and rebooting can't even complete setup )
Again tried flashing 4 files recovery firmware BL+AP+CP+CSC via odin this time with PIT FILE re-partition checked in odin. everything Pass smoothly without errors in odin but again freezing black screen on setup. (same issue)
Tried factory reset+wipe cache after flashing (still same)
At last i tried flashing custom rom "kongloi s8 port final repacked" from twrp after clean wipe it worked finally now no reboots or blackscreen freezing nothing everything works perfect for 2 days.
Then i thought now my phone is fixed so why not try stock again.then again same problem came back.
1 thing i realize that when i run custom kernel specifically a permissive kernel my phone runs without issues.
currently stuck with khongloi rom s8 port this is the only rom working on.my device and cant go back to marshmallow.
I am looking on Google and xda constantly from many days but can't find correct answer.
So please please someone point me out what is this issue
Sorry for the long post TIA
Hello guys (and girls)
I'm experiencing a "throw out of the window" issue with my mother's s3 mini.
It stuck on a reboot loop. Common issue you might say. So, I will give you more info on that.
1) It will not enter recovery mode. Just ignores the keys pressed and keeps looping.
2) I can enter download (odin) mode. So, no Power-button stuck issue. And that rules out "Up" and "Home" buttons broken as well (as a reason not to enter recovery)
3) Using Odin to upload firmware? Operation successful, patient dead. Meaning: I have tried flashing TWRP and CWM, and guess what? Procedure is successful, but the outcome is the same. I still cannot get in recovery, or boot.
4) I have also tried flashing official rom, but nothing changes.
I will try flashing a custom rom, but my hopes are very few Any propositions on what do I have more chances to be lucky with?
Thanks for any possible help and the time to read my problem
