S9+ stuck in boot loop... any advice? - Samsung Galaxy S9+ Questions & Answers

Hey guys,
I woke up the other morning with my S9+ rebooting every other second or so. The screen loads the "Samsung Galaxy S9" powered by knox screen and then reboots right away. I can get into download mode easily and can even access the safemode/reformat screen with some luck (if I let the battery drain I can usually pull this off if I plug in the phone and immediately try). I have tried resetting to factory defualt, loading in safe mode, normal boot, and reflashing the official ROM. No matter what I do, the behavior persists. Verizon is sending a new phone, but it won't get here before I leave for a business trip and there is that inside of me that wants to be able to fix this with my own two hands. Any advice? I used the verizon ROM off of sammobile if that is helpful and odin gave me the green light.

nooooo ! I can't believe it !!! we are damned !
I went from galaxy S3-4G (bootloop issues due to bad internal memory chip) ..... to LG G4 (had the f.ing LG bootloop) .... and now S9+ and THIS ?!?
Sorry guy, if bootlooping and you did nothing to get there just before the issue (no flash, no update, no nothing), then it's faulty hardware, nothing to do about it :/

Thanks for the candid response. I'll have to figure some way to get a temporary phone for my trip.

Boot-loop nightmare
I got a new S9 3 days ago and am now on my 3rd new S9. The previous two wanted me to update my system- a a security update. With both phones it sent it into a boot-loop that no one could flash or hard re-set, even when I took the phone back to the store I bought it from. I have the update set to later on my 3rd new S9... afraid to hit update for fear of it happening again. Any ideas as to what is causing this? I run my business off my phone so I would like to use it (;
I didn't transfer over any of my apps from previous phones! Puzzled. Help.

Has my S3 bricked itself?

Hi there guys, In need of some help here! Had my S3 for 8 months now and its been fine, Never rooted, Always been on stock OS's from day one.. About a week ago I started to get random reboots and freezes, A battery pull would fix the issue for a while but then it would come back again, They became more and more frequent and then I did the latest update, 4.1.2 (I think) It worked fine for a day and then yesterday morning I had like one restart, After a battery pull it worked fine. Put it in in my pocket and carried on doing my work. When I next looked at it it was on the samsung boot screen, I thought it must be another random reboot, But this time it kept looping over and over, Makes the little jingle sound with the samsung logo and then repeats constantly.. I did a wipe data/cache from the recovery mode and that didn't change anything, I then flashed the latest unbranded UK OS via Odin, But that didn't do anything either, The only difference that made was that it gave me a false hope as when i booted it, It say 'Optimising Apps' an then went from 0 to 30 something but sadly, After that it began its looping of the samsung logo again. Anyone heard of a case like this? Where an unrooted phone 'bricks' itself? Could it be hardware?.. Hopefully someone can help.. I hope Samsung UK will fix this under warranty! Fingers crossed they will! Any help would be much much appreciated.. Thanks!
It sounds like a partial SDS hardware fault if you stayed on the previous UK ROM and didn't update to XXELLA until just a week ago, return it to Samsung for a new motherboard.
ELLA contained a fix which prevents SDS, but won't cure it if it's already happened.

Which firmware are you using?
as Boomboomer said, if you never did a firmware upgrade before your last upgrade you are probably encountering issues with SDS. new motherboerd required
Good luck!

Help Fixing Hard Bricked Galaxy Note Pro 12 Reward

Hi,
I have one hard bricked Galaxy Note Pro 12.1 2014 Version tablet I bricked while loading custom ROM. I mistakenly popped out the external sd card that the rom was installing from. I was having some trouble with battery issues and was thinking a fresh install of the custom rom would fix it.
When the external card popped out while the rom was loading from the screen said it failed. On reboot the screen goes thru Galaxy logo then goes black. I tried installing recovery images and whatnot thru odin. Some would pass some would fail. And on reboot it just goes thru logo then goes black. I could see its on but nothing else. It does accept a charge though.
Its probably completely broken and at a complete loss but I thought maybe there was some chance. I think it might be possible to repartition or something to that affect but thought I'd see what is possible.
FYI: Not under warranty. Knox is tripped. I am willing to provide a $50 reward to whomever can walk me thru a possible fix. Yeah I know, if you help and it works again I could just say it still doesn't work but all I can offer is my word that you will be rewarded if it gets fixed.
Thank you for any positive feedback.

Solved
Kies was able to fix this problem. I tried odin a recovery tar , everything numerous times, even kies several times, nothing would do it. Also tried odin a stock rom and that helped a tiny bit. After installing stock rom several times (at first it didnt want to and would fail) it finally did go thru on like the 3rd try installed and passed. But then it would only go to samsung logo and lock up. This morning it tried kies again and miraculously it didnt lock up like it did before and install all the way thru. On reboot it went past logo and turned on completely as new. Moral of the story, have faith and dont give up. I almost trashed this thing and was ready to press the buy it now button for a new one but I decided to insanely try again as if some miracle might happen. And sure as sh#t a miracle happened.

No matter what, LG D620k keeps bricking

Hello all.
I´m pretty desperated at this point. No matter what, my phone (LG G2 mini D620k, I have 2 years with it) keeps bricking. Keep in mind I´m a noob in this world, so I´m looking for help here.
This started like 2 months ago, it bricked so I searched on Internet and did the hard reset. It worked well, for a while. I downloaded all my usual apps without rooting it, then suddenly: bricked.
Another hard reset, and again, it worked. So someday it started freezing, apps closing, so in like a week I used 10 times the LG Mobile support tool to fix errors. It fixed the phone but just for 1-2 days. So again, I did factory reset (this time from the phone, it wasn´t bricked), rooted it, debloated it, and worked fine for 48 hours. Last night it again, from nothing, bricked.
Did hard reset again. I'm asking here: what is wrong with the phone? What is causing this? Is an app? Too many apps? Hardware? Battery?
I love my phone but I´m tired of sitting 3 hours every 2 days fixing it. Cannot afford a new phone or looking for specialized help, so I´m asking here for help.
Keep in mind I´m a noob in this. Can someone help me?
Sorry if this matter is already answered, I did a search and found nothing like this.
Sorry for my bad english.
When you say "bricking" do you mean bootlooping (the LG boot animation keeps playing)?
If so, try to capture a logcat while it's bootlooping via adb. Let it capture for a minute, or so. Then send it to me.
Then, pull out the battery for a couple of seconds, put it back in and power up the phone. Does it still bootloop?

I have the same issue!! I've tryed every CM Rom, custom roms, stock roms and now latest RR, and still the same problem. After flash I install only FB, Messenger and Insta (it's girlfriend's phone) and after 1-2 days phone gets bootloop (only RR logo). I have to do hard reset and flash again whole system to work properly again (for a few days).
I gave my G2Mini to service (not LG Service) but they said that its motherboard issue (probably some boot memory is broken and has memory "leaks") But I think that it cant be this. If this is possible I would try to flash whole system on SD card not internal memmory, maybe this will work
help!

Grab a logcat via adb.
Install adb and Google's drivers (for custom ROMs, LG's for stock ROMs).
Let it record for a minute and give it to us.
I managed to install CM13, worked fine for a month I guess... started with random bugs "x app stopped working". So I restarted the phone and it's in eternal logo when I turn it on.
Since I'm a totally noob at this, I can't find a noob-friendly guide to make it work again.
:crying:

Wipe /data in recovery.
If that doesn't work, reinstall the ROM and 'pico' OpenGApps

Managed to connect it to my laptop (I could't before), used LGMobile support tool, back to original rom. I guess it will be matter of time to get same errors as before. At least it works again... idk for how long :s

Bootloop remains even after Stock flash in ODIN

Hello guys, I have a serious predicament that needs to be solved.
I haven't did anything major to my phone in years so the past couple days have been a nightmare. Ever since I did a wipe of cache partition after trying to get rid of this "unfortunately, contacts stopped working." message, it's sent my phone into a spiraling disaster. (I have been using stock 5.0 rooted rom for at least a year so idk why the sudden issues)
I've literally tried every method imaginable. I even tried flashing with different versions of Odin and still the exact same problems.
I can get my phone into DL mode easily but Recovery mode only works if I have the phone plugged in at this point (Actually, it seems like the only time when my phone wants to work)
Every time I'm done flashing, it'll load all the way up to the T-Mobile screen then restart the loop all over again :/
Really need help seeing as I need to get this situation handled before work today, thanks!
Nevermind, after more research, I decided to order a new battery and the problem is solved.
Bootloop solved with replacement battery

A replacement battery also solved my boot loop issue. Prior to replacement, it would boot to Galaxy S5 screen, and then reboot. Replaced battery and boots. Put the old battery back in, and it boot looped.

Need Serious help with my device!

Hey!
So I have been using an android phone from 3 years now and I have been stuck in an huge problem! And I need your help in order to solve this problem. Here is the problem so basically I have a Freetel nico (Japanese brand) which is about 3 to 4 years now running on top of stock kitkat rom or in other words the same rom when I unboxed it. After few months my screen cracked on the bottom near the capacitive touch keys. After the crack the home buttom stopped working! I was all okay with that and the next day my notification panel started glitching and stopped showing any notifications which was really annoying. Now I knew that there some serious problem, so I taught of resetting the phone so I went in the setting and tried factory reset. After few minutes it didn't go to system recovery but the phone just restarted itself. I tried it once again and got the same problem, next step I had was to hard reset it by going into the recovery. When I hold the button and let go it didn't take me to the recovery this time also. So in conclusion I came to know that there was no recovery inside the phone (I did erase the phone through recover about 2 times before this incident everything went well during that time). Moving on I rooted the phone and installed SuperSU and other softwares that could install recovery mode to the phone. I got the same result this time also, I also tried installing a different rom through the stock system update app same result.... After a year of all this work I taught it would be best just giving it to the company service center but I came to know that the company had no longer selling this device and there is no service available .
After all of that tries above I still continued to solve this problem I tried ADB resetting it through pc no luck here also! So if you guys could recommend me some apps or softwares I could try in order to reset my phone please do let me know in the comments. Or you could also ask any scripts that you want to know from the phone which could solve the problem I can do that also!
Thank you
Darshan
