[HELP] no bootloader? - Galaxy S III Mini Q&A, Help & Troubleshooting

Good morning guys,
I'm not sure how to explain the problem.
It started when I downloaded Telegram (Whatsapp + encryption = <3)
The phone crashed and the problems began. Everytime it started, its trying to download Telegram again and sais, that there is an error.
Also it randomly crashes.
And somehow my phone is loading a "image" each time its starting.
That means, i can flash, change, root, whatever I want to do, but as soon as I restart the phone, its booting into the same.
Hard to explain. Whatever I changed, send or recieved - dissappeared.
TWRP somehow also doesnt work, its not even booting in it.
Also, I cant get into the Bootloader, as soon as I do the Vol+ Power combination the Samsung logo appears and nothing happens, i have to pull the battery our to restart it. Well, the phone vibrates once, but thats all.
In the download-mode Im able to flash with Odin, but that doesnt changes anything after the restart.
Im not sure, maybe I clicked RE-Partition while trying to fix it or my flash wasnt clean or sthing like that, but atm the phone is unusable.
Hope you got some ideas

[Q] cannot start galaxy s after update.zip

Hello
I am in a great panic mode.
I applied this lagfix : forum.xda-developers.com/showpost.php?p=7587405&postcount=417 and since I did it I cannot use my phone.
I am not able to start my phone. It shows me Galaxy S logo, and after that I hear the start up music but nothing on the screen (no animation). Pressing hardkeys does not do anything either.
Above all I cannot even enter my recovery mode. When I press volumedown+poweron button, the screen keeps showing me Galaxy S logo and it does not go any further.
Please help me if you know how to getaround.
Were you rooted when yoou applied update.zip?
Anyway,did you try to shutdown the phone removing battery,and then try entering recovery?
the fix did not mention I had to root my phone, it said it would self install.
Yes I did shut down after removing the battery, and then I am trying to get into recovery using volumedown+poweron button but I am not able to get into it. All I see is Galaxy logo and hear start up music after that with nothing on screen.
OK, I am able to get into recovery mode.. I was trying wrong combinations
Now what should I select I get these options:
1. reboot system now
2. apply sdcard:update.zip (will never do this again)
3. wipe data/factory reset (should I do this)
4. wipe cache partition
yes.. you should do 3.) wipe data. If that doesnt solve your problem, you need to flash firmware agian

Why did you choose to install something not on main page, something obviosuly not very tested and something 2 month old (god knows there are close to ten newer or more tested fixes).
If you can access download mode, than reflash. If not... Well, try the exotic methods (dont know them, as I have working 3 butons)
Hey, for a second I thought it did noy fix my problem as I did not get my animation screen and ony heard music.. But then suddenly it starts up
I think I lost my animation on start up though
I still see that MCR Scripts icon on app loader screen, How could I know if its enabled or disabled?
Thanks a lot guys.. XDA rocks .

I regret doing something like that.. But it was really confusing as there are so many topics on the forum and I was really tempted to solve the lag issue I started facing recently (I installed too many apps).
hey i have the same problem.. my phone goes up into the Samsung logo and hangs there forever, occasionally blinking and making a weird vibration. i've tried factory reset but that doesn't help..
How do i flash firmware again?

[SOLVED] Cannot enter flashmode since flashing nAa 2.6.29.6-nAa-ics-04

Hmmm...
So my Galaxy SII just died, and I need a phone, so this X8 I had lying around seemed like it would do.
I had some very unstable FW on it, so I thought I'd find something else.
Decided on kuyaDROID and CWM'ed it. It'd boot with strangely garbled graphics.
So I thought I'd try some other kernels.
I've flashed a few different ones, but this last one turned out to kinda brick my phone in a way.
I flashed the 2.6.29.6-nAa-ics-04 one trying to get kuya to work. I now have a phone that'll reboot indefinitely, sometimes showing an "nAa" logo sliding in from the right. This is mostly when I connect it via USB to my laptop. Otherwise, it'll turn on the screen, showing black, then hang for a while, then reboot and do the same.
This wouldn't be a problem, except I can no longer get it to enter flashmode so that I can flash a working kernel. Back+plugging in USB no longer makes the flash tool recognize the device. I just get a lot of ding-dong and dong-ding sounds from Windows while it reboots and reboots and reboots.
I'm not sure where to go from here... Any ideas?
Thanks
EDIT: Feeling stupid — it wasn't the phone at all, it was Windows which had gone into some funk of not properly recognizing the device. A reboot allowed me to flash once more

Phone restarts every minute, cannot enter recovery mode, Please help!

As I said, phone is restarting every minute, it cannot enter recovery mode by using 3 buttons. I've tried hard resetting, but whenever I press the button to erase it, it either does nothing or it restarts again. Also whenever I change some of the settings they revert after a restart. I've tried flashing some rooted roms with odin, and it said "pass" but phone still remained the same. I've tried flashing pit files, the three button recovery and all, but still nothing did any good... Is there any way I can fix this? Is there any way to find stock official images and install them without odin, like LG's software update kdz, or HTC official installer files? Is the phone just dead? Please help guys!
P.S I've posted it in general discussion too, because I don't know the right place for the tread! Sorry if I am making trouble of it!

Soft brick help. Twrp installed Android won't boot custom rom

I didn't want to make a new thread. But I've searched high and low.. And nothing has been answered. So here's my story. I have a note 4 sm-n910T. When I rooted the phone everything was fine and good. I then decided to give it to a family member. I flashed it back to stock.. All was fine for a while but it started acting up. Like randomly turning off and not responding to a charge or any commands to turn on into other modes... I had flashed stock again. All was good.. Till now. My madre and received a Ota update, downloaded and installed the update. When I pressed ok to reboot new update. The phone never came back on. So I went through all the fun stuff. I tried kies.. Kies days unsupported device connected.. There is however talk between the two because it's pushed errors onto my phone as well as has tried to download the stock rom. But every which way I've tried it fails. Next. I decided to go for custom roms... And flash cf-chainfire auto root. Then twrp.. Then install supersu.. Then a rom from twrp. Now here's where it gets interesting. Nothing would pass odin if I had auto-reboot and f.reset time checked.. Any and all roms.. Files..etc would only pass with auto reboot checked and f. Reset time unchecked. At first everything seemed ok.. I was able to actually get cm 12.1 installed as well as gapps. But only the one time.. Which you'd think was good enough. But here's what has happened and what I can't seem to fix. The phone yesterday after having everything installed and sitting at home untouched.. I came home clicked the home button.. And it came on.. I scrolled a few pages.. Thought.. OK cool.. Let's get madres Sim card in and call it a night.. When I turned the phone over.. (didn't even take our the battery) tried to see if I could fit the sim in.. Which didn't.. I then turned the phone back around just Cuz I wanted to make sure it was awake.. The screen was black.. I figured it was in sleep mode.. So I hit the home button.. No response.. I hit the power button.. No response. .. The phone had turned itself off.. And when I tried to turn it on it wouldn't. Now mind you the phone has these weird phases where when I try to install or flash a rom and it fails.. And I'm forced to remote battery.. A good portion of the time it won't turn back on.. Sometimes it can be instant.. Others.. A few mins.. Sometimes even longer for it to respond.. Right now I have been accessing twrp.. Wiping all data.. Davik...cache.. System.. One by one.. Then installing a rom.. I go for a reboot.. And I get a black screen. I need help.. I'm running out of ideas and basically just fishing random idea attempts. I'm no scared to brick it.. So all ideas are welcome. Plz. Thank you.

Also how important is f. Reset time? I don't totally understand it. Next.. What about having the roms and files I flash on internal memory instead of sd. I'm not sure if I can access the Internal storage. But if I can does that help. Also I cannot access Android at all.. I can either access download mode or recovery. I have been using an external battery charger to charge my battery as well. Due to it doesn't read the charge... But! It did read a charge just fine when I had cm 12.1 working.
I would suggest:
1) In twrp wipe system, both the cache's and also data
2) use ODIN to install the stock Note 4 ROM
see -> http://forum.xda-developers.com/not...uide-odin-to-stock-unrooted-firmware-t2957156
3) When it is finished unplug the usb from your computer as the phone is rebooting
NOTE you might want to uncheck Reactivation Lock in Settings - Security first

Answering question one.. I do that already. I wipe everything one by one except sd... Answering question two. I have tried that already and odin fails.. However I'm sure if I tried to flash the rom and didn't check f. Reset time it might work. But as for flash stock.. I have tried several times.. I can't say one error or another I'd a cause because I get a different one each time.. What is the purpose of f. Reset time in Odin? I've searched it and to me the explanation didn't make since.

Reactivation is unlocked. Also I wouldn't be able to change any setting in the phone.. As the phone does not boot into Android. I was just lucky enough to have usb debugging active before this all happened
I am not sure what that is for
But every time I have done a flash it works if you use the steps I had there. (Not really questions)
Sorry I do not have anymore ideas.

Are you booting your phone into download mode before you use ODIN?
(I know it's proly a dumb question but just in case)
Yes I am in download mode when using odin.

Just now I did another full wipe and wipe of cache, davik, system, internal memory and had a successful install of cm12. 1 with gapps.. Everything installed.. Clicked reboot and the phone never came back on. I will try your idea next. I have not tried an idea where I use twrp to wipe everything and reboot into download then do stock rom via odin. If the phone does boot into download from twrp recovery I will try this one time with auto reboot and f. Reset time checked.. If it fails I will try it again with f. Reset time unchecked. I am currently not by my laptop to try this so it will have to be much later in the day.
To boot into download mode: Power off Note 4, hit all 3 of these at the same time until it wakes and vibrates - Power Button, Home Button and Volume Down
I know how to do that lol. I know I'm a junior member. But I'm somewhat intermediate. So cm12. 1 has booted.. However it didn't from a reboot of a flash.. I just took a while shot.. And powered the phone on.. And it booted.. I'm pretty sure in going to run into the problem again.
OK - Well you never know!
I am only a senior member 'cause I am older than Dirt!
Lol. I'm oldish. And trust me this lucky catch I got.. Is temporarily. There is still boot issues. I fear when the phone goes off or is turned off that it won't come on. I do not have a sim card in the phone at the moment which means I can download helpful apps. Like supersu. .. But so far I was able to check settings and get what I can prepared. Also if like to keep this thread open as a log or research tool.
Alright so I like the rom sit most the day.. With minimal to no use.. Most of the day it was fine.. At one point I took a picture and it did as it should.. I cleared all open tabs.. Took another picture and I got a error saying camera wasn't connected.. Finally the phone froze up and rebooted.. And the Camera worked.. Gave it another rest.. Came back to it checked the camera and it was fine.. I put it away for like 10mins then decided to check recording. When I did the phone was not responding to turning back on from sleep mode. Now for as long as I can remember even before this initial issue started.. I was having thr same problems with the phone not coming back on from when in sleep mode.. I dunno what the cause is or hoe to approach it to fix it.
First attempt was to put it to a charger... Registered no charge.. So I removed the battery.. Gave it a few mins.. Pushed down power button.. No response. Something is off with the boot menu.. Like the boot img. File
And finally it's back on.. Normal boot.. I didn't boot from download menu or recovery.. But in all honesty I'm 100% sure this will just happen again.. It seems to happen when I put the phone in the charger.. Then take it out and play with it.. For now in going to let it sit till the battery is in caution. Then charge it. I still have not added the Sim and loaded apps.. I feel that will be a overload of cpu and will most certainly freeze up and crash the phone
Ok, so up to date now.. Here's what's going on. The phone struggles to reboot from any on screen commands.. Like if I'm in Android.. And hold power.. Click reboot.. Then say like recovery.. Or anywhere.. It just turns off... If I also do this in twrp.. Say like install a rom or supersu.. It won't reboot... But! After it turns off.. And I wait a while and power it back on.. The file.. Rom etc was installed. So I do now have supersu installed and busybox. But the issue remains..which is a unstable OS.. Nothing to do with it being custom os.. But there is something wrong with the booting process.. What can I download if any apks.. Or files to help this?

Might be stupid I know, but try wiping clean your SD card (back up a copy on your pc first) as well when you factory wipe and make sure that after that, you only add the files you need for recovery. Start up the phone after reset. To get a backup, if you're synced through google, you'll get everything back. If not, only copy your backup from titanium back into your SD card.
I went through a very similar situation last week. Long story short, it seemed the SD card had copied files which would interfere with the system.
Curious, did it happen after marshmallow update?
And did you try to downgrade back to previous lollipop version?
I assume it was Marsh that I was trying to Ota too. I was unable to boot successfully after that first try, so I honestly don't know.. I'm going to try your SD card idea. .. But once all that's done. Are you wanting me to redo a full rom install like through and wipe system, Davik etc etx? Or like wipe everything and start from like odin installing a recovery and so forth?
I ask these questions because.. What if I was to just take the sd card. And format the whole thing.. And out it back into the phone? I mean I might try that first then the other option.

Well even if you format and you put the SD card back in with all previous files, same might happen.
When you format, just wipe all. Then if you want to downgrade, you need to have the previous version bootloader and baseband FIRST prior to putting the firmware ROM.
A simple (restore) wipe would just keep you at current version. And you can't easily downgrade the easy way from marsh to lollipop. Believe me, I learned the hard way
Flash through ODIN

Constant reboots

I've been facing a weird problem with my G800H since yesterday. The phone will reboot constantly. It will boot into android, I will even be able to open apps, but it will suddenly reboot after a minute or so. I didn't do anything to my phone for it to start doing this. The weirdest part is that the rebooting will happen even if I am in recovery mode (TWRP). Also, the phone will automatically turn on if I take off the battery and put it back in, something that never happened before.
I use stock 6.0.1 (rooted) and TWRP 3.0.
Things I've already tried:
Charging it;
Safe mode (same problem);
Taking off SD card (who knows);
Wipe cache/dalvik (phone restarts before finishing);
Re-install ROM ( Download mode (ODIN) doesn't open, insta-restart after 'press volume up to enter odin').
I really dont want to do a full factory reset, only as a last resort, as i don't even know if it will have time to do so, or even if it will fix it. Does anyone know a way for wiping the cache without having to format it ( takes too long in TWRP so phone restarts before finishing ), or maybe have some other way of entering download mode, maybe with adb, or finding out what went wrong. Any sugestions on what to do or what happened?
I (my wife) have the exact same problem, I bought a new battery which didn't solve the problem.
Also tried a factory reset, didn't help either.
It is a non rooted phone...
Next try is a custom rom, hope it helps...
Install an app that records logs like Logcat, set it in record mode and wait until the phone reboots. Then look through the file, study what happens near the end when the phone turns off. You'll most likely find the cause there.
