[Q] My device won't start up - Samsung Galaxy Note GT N7000

I have got a Samsung Galaxy Note GT N7000. My friend has actually made an update (claims to), and now my phone won't boot! I get the first Screen as
"Samsung Galaxy Note GT N7000" after which the Samsung logo splash should follow, but simply doesn't. All I get is a black screen. With the Volume Down + Power + home I get the "Downloading Do Not Turn Target off" and it just stays that way, I don't really think it is actually downloading anything. With Volume Up + Power + Home I get "Manual Mode" of some recovery mode. Wherein I have
Reboot
Update from External SD
Update from Cache
Wipe External SD
Wipe Cache
Reboot just simply does the same, I get a black screen after Samsung Galaxy screen. What could be wrong with my phone? I have no idea, help please.
Edit:
I have Odin downloaded, and in the Download Mode, I get that COM:ID port added, but I have no clue where to proceed from there on.

[Q] I-9300 bootloop and no recovery

Hello,
I have a S3 which is stuck in a bootloop at the samsung logo.
when i turn it on it shows the logo for some seconds then the screen goes black and the logo re-appears.
i can not boot into recovery mode, but download mode is working without a problem every time.
i tried flashing stock firmwares with odin and also tried kies emergency firmware recovery. the flashing always went without any problem, but it had effect. whatever i try, i am never able to boot into recovery and still stuck in the bootloop.
in some tries after flashing the screen just shows the samsung logo forever, but after rebooting it once it then is stuck in a bootloop again (shows the logo - screen goes black - shows the logo...)
i also tried flashing TWRP and CWM via odin, but again i can never boot into recovery mode.
what should i try next?
thx alot for any helpful comment

You can Try this:
1.) Pull out battery
2.) Put it in again
3.) Press Vol up + home + power
4.) When the Samsung Logo appears let it off
I think you press the Buttons too long.
I had the same problem!

i really tried everything, it's not working. btw with i am stuck at the very first image, where it says "samsung Galaxy sII GT-I9300".
i dont think it's just the way i press the buttons because i can reach it on my s1 and s2 without a problem, it's just not working on this device.
could some setting like "nand erase all" in odin help? in other threads there is sometimes mentioned that the internal file system might be screwed up and in those cases a simple odin reflash does not help anymore...
Nand erase will usually hard brick it. Try the rescue firmware from general forum, sticky thread. Follow the guide exactly as it includes a pit file.

thx, but i already did that (multiple times) and flashing via odin always succeeds. then the phone reboots and is stuck at the first samsung galaxy s.. screen. twice i managed somehow to get into recovery (after flashing cwm6) but it then randomly rebooted.
and i dont think that the power button is stuck because when i am in download mode it is perfectly fine it never reboots itself unexpectedly.
Had a similar issue on my tab2 p3100. It all happened when I tried flashing a custom recovery from rom manager.
A bad flash of anything related to recovery or bootloader could be a probable cause.
I remember a knowledge share on one of the threads describing this issue and as mentioned on it all I had to do is this:
1) switch off the device and plug in the charger. This would light up the display showing you the charging status. The status has to show if at least your bootloader part of the phone is fine.
2) plug out the charger and immediately press the three buttons (home + vol up + power) get into recovery mode. This step has to work and help you get to recovery mode.
***Note : the interval within which this step has to be performed is too short since the display would turn off immediately as soon as you plug out the charger. A bit tricky too so you have to be fast. If this misses getting you into recovery, pull out the battery and put it back again. Repeat step1 and 2 again.
3) upon successfully getting into recovery, perform wipe data, cache and select reboot phone from option available on recovery again.
Allow the device to boot. This could take a while since you have performed a data wipe and may prompt for first time set up.
I was able to restore functionality on my tab after these steps and like ppl learn from their mistakes, I then learnt that recoveries and bootloaders are things that needs to be done with a pc only.
Worth a try if you have tried other alternatives and found no go. may help. Who knows..
all the best.
thats also not working. i tried to get into recovery since two days now...
i also tried the steps from this thread: http://forum.xda-developers.com/galaxy-s3/help/solved-pit-bricked-dead-problem-gt-t2535367
but again, after i flash the cf-root (successfully) the phone does neither boot into recovery by itself nor can i do it by hand...
its crazy... in download mode i can see the model number (GT-I9300) and i thought as long as the model number is there and i can enter download mode there should be a way to recover the device.
but i cannot think of anything to try that i have not done yet
If the rescue firmware didn't help then it looks like the emmc chip is damaged.

is there a way to make certain of this? how can i tell if it is really a hardware damage and not just a software brick?
i just dont want to let the phone go, it looks still so shiny
is there anything else that could cause the phone not booting into recovery mode after flashing custom recoveries?

Same here, still didn't found how to fix it.. I guess our motherboard just died..
Howewer I have a solution that "almost" worked for me.
Get a stock firmware in odin and turn on Nand erase and T-flash
When it's done phone reboots and you'll see just "Downloading..." mode when you turn it on.
Then got to Kies and Select firmware recovery...
Enter s/n and model name and wait for the flash to complete.
With it , I got past boot logo and actually booted into android but the phone crashed because I guess I have a memory issue..
Well , gl. If you don't find anything else helpful , try going with this method..

S6 Edge Stuck in bootloop - can't flash stock rom

UPDATE: I got stock firmware flashed on it, but as soon as it finished, it just stuck in the Samsung Galaxy S6 Edge boot screen, and it won't even allow me to access recovery mode so I can wipe cache and whatnot. I'm running out of patience with this brick of a phone. It just goes straight to the same boot screen, not allowing me to get to the recovery mode. Are there any alternative ways to enter recovery mode, or alternative ways to wipe cache and partition? Please, any advice is welcomed.
Thanks in advance.
Try different odin version and cable before you messing with pit.

I had tried using three different versions of Odin, 3.07, 3.09, 3.106. I also used multiple cords and multiple versions of stock roms. And still, no success. It won't even stay off, every time it juices up, or is plugged in, it goes straight to the Samsung Galaxy S6 Edge boot screen and stays there.
Mind you, I am not too familiar with anything outside of stock roms, some custom roms and rooting. Have not tested out much more than that. Any noob-friendly advice would be welcomed.
I had nand write start error once during downgrading my s6 from 6.0.1 to 5.1.1. I just tried odin 3.10 and it got flashed successfully. I was lucky then.

Well, I finally got one of the firmwares to work, it ran through Odin and everything just fine, but after it was done, it basically did the same thing, it stayed on the Samsung black screen, except without the red writing at the top..

I can't access recovery, the phone won't turn off, so as soon as it has any source of battery life, it just goes straight to the samsung boot screen and stays there.
Hold vol down+power button for 15-20sec. As soon as it reboot, hold vol up+power+home button to enter recovery.
Sent from my SM-N920C
I've tried that at least 50-ish times now, It just does not work, I tried it with a second or two delay, I tried it immediately after screen turns off, tried it so many times. No matter how long I hold them down for, it just stays at the boot screen. I can get to download mode just fine, but for some reason recovery seems to not be working.
is it a bootloop (it keeps restarting or it is frozen on samsung logo) ?
if bootloop you can try: plug in power corde. press and hold both volume buttons + home + power untill it shuts down. unplug power corde. press and hold home volume down and power for download mode. get another rom and flash it.
Hi i am having exactly the same problem can boot to download but not recovery, let the phone run out of battery and as soon as you plug it in again bootloop, i was running crisscross marshmallow rom ,custom kernel i have a backup but am not sure what or how to flash correctly in Odin any help would be much appreciated thanks .
Edit flashed firmware from sammobiles worked a treat .
Any updates on this?
I have this exact problem however I never attempted rooting my phone or changing anything on the firmware, I was on YouTube when my s6 edge crashed then entered boot loop, I CANNOT ACCESS recovery mode ,but I can access Odin mode. WTF everything is stock on my phone, never even heard of 'bootloop, Odin mode' before this happened .or even had to access my recovery mode on my s6. As I search the web for help I find solutions that require recovery mode, but I can access it. Apparently bootloop happens when people try to root but I never tired that. I don't even know what that is!
This just happened to my S6. Was watching YouTube then it crashed and entered a boot loop, can't access recovery, only download mode.

Flash stock Rom via download mode with Odin
U can get stock Rom/firmware from the Sammobile website
Why do you guys never manage to make backups? Hahah

I had the same problem and it was a problem of the power button. One way to try if that is your problem is to take out the battery for a while, and the put it in. If the device turns on automatically it probably means that your power button is somewhat stuck.
In my case, the button wasn't stuck but it had the same behavior so i had to open the terminal and remove the power button. That fixed my problem but now i need a charger to turn it on.
same here D:

Can you get into download mode or recovery mode?
If you can get into recovery mode then wipe data/cache.
If you can get to download mode flash stock firmware and start again.
To get into recovery hold only down and power for 10 seconds, as soon as the screen goes off to reboot switch to recover combo, home and up amd power for 20 seconds until it boots to recovery. Try that first.
