[Q] Boot Loop with no recovery mode

Ok so I'm new to the thread and basically to android tablets, so please forgive my ignorance if it should become prevalent.
I bought a Galaxy Note Pro 12.2 32GB wifi and had it for about one day. I performed a factory restore on the device in which it froze for about 2 hours. (this is probably the stupid part) I turned it off since it was not progressing after a long time and it booted up as a new device. After about 5 minutes of use, it randomly restarted and went into a boot loop. About every 15 or so boot screens, it sometimes boots up, then freezes and goes back into a boot loop. The longest it stayed active without resetting was about 10 minutes. After hours of research, I have done the following
Tried to boot into recovery to no avail. It just continuously pops up the device name screen
I have tried to flash the device with a stock rom in odin 3.9.
It recognizes the device but hangs at the Initialization stage. Sometimes it will give me a fail notice saying that it couldn't open the COM port
I've tried it on another computer, changed usb ports, powered on and off multiple times and nothing changes.
please let me know if i've forgotten anything. Any help will be appreciated.
Also I live in Japan, so if I can fix it myself that would be nice since this device isn't sold here yet, I'm not able to get support from a store. I'd like to avoid waiting a month sending it back to america, replacing it, and getting it sent back. Thanks in advance ^_^

Make sure you have the correct and latest Samsung drivers for your tablet.
If you have an SD card installed, try removing it and see if you can boot up and get it stable.

Wow, you rooted (void warranty) on a day old tablet on a platform that is new to you? I've been rooting Android devices for over 3 years now and have had mine for a week now without root. Don't get me wrong, I have a list of things I want that require root and it will be happening but I figured I should at least run it for a couple weeks to make sure no defects pop up before I void the warranty. Good luck to you!

I've installed drivers a few times. No go.
I'm on it now and the boot loop seems to have stopped, but I still get random restarts. But each time it restarts, it's from factory, so it doesn't save anything I download or any settings such as enabling debugging in the developer settings.

I didn't root, and I haven't voided my warranty. I can still get into download mode and my flash counter is still at 0. I never tried to root, I simply wanted to flash to stock, from stock.
[Edit] I'd also like to mention that Odin has not successfully done anything, Every time I tried to flash it was done with a stock ROM, and everything that has gone wrong has occurred on nothing but the stock ROM

Is it possible that I need a pit file for the device since no version of Odin will get past initialization? ....if so where can I get one for the this model?

If you are not rooted and you have a boot loop I'd be returning the device for a new one...

I hate to agree since you would have to wait for a while to get the replacement, however the device sounds to be defective. just my two cents as a developer, if you flash anything to the device, root, a new image, or even the factory software, Knox will be tripped and the counter will go from zero to a one. My advice would be to get a replacement for the defective one.
Developers don't need no stinkin' signature!

Huge 3rd.
Device should just plain WORK out of the box. There shouldn't have been a need to flash stock to begin with.

One last suggestion, factory reset from recovery. From complete power off, hold volume up+home button+power and after a few seconds let go until it boots into recovery. From there wipe cache, wipe davlik, and factory restore. Good luck!

Yeah, it's unfortunate, but I have to suck it up and just pay the shipping back to Ameica....then again for it to come back. Just wanted to do everything I could before I had to send it. Thanks for the input though. I guess I learned quite a bit researching processes and terminology which will be helpful in the future. ^-^

Tried many times. The device pretty much gives me the finger by going blank and repeatedly showing the boot up logo when I hold the buttons down.

I voided my warrant after having mine for about an hour (though not new to Android). I did all my random "OCD does it work as I expect/want" tests and it passed, so I rooted. Had it for one week now, and I absolutely love everything about this tablet.

IMO, it will be worth it. This is my fourth tablet, and is the first one I've not had buyer's remorse with. Luckily with the gift credit for Google I was able to get the non-Tegra equivalents of some of my favorite games, too.

After doing research, I think that even if I get a new one, I want to root it. With the problems I've read about for kitkat 4.4.2 I need to know how to fix problems, and start with a fresh install of roms and know how to use custom recovery. I haven't done anything yet, but I was wondering...
Since I'm stuck in a boot loop with no stock recovery, can I flash a custom recovery to fix my issues, flash the stock rom that is on sammobile.com and then root after that? From what I understand this is a soft brick since I can still sometimes access the device. I worked out why I couldn't access the device with adb and now it shows the device as listed. It stays on long enough to where I could flash a recovery before it restarts itself. I'm not trying to do anything stupid, just getting information before I pay the shipping for it back to the states. I've checked the knox counter in download mode, and it is still set to 0, so I haven't voided the warranty yet.
Any input would be greatly appreciated.

It's odd that a new device would not have recovery. I don't want to insult you, but just making sure we covered the basics, volume up+home+power gets you to recovery. The boot logo will flash about three times, make sure you're still pressing all three buttons, then let go after the 3rd flash of the boot logo then you should be in recovery. Volume down+home+power takes you to download mode, this is where you flash roms and recovery. I read in another post about someone not being able to get in recovery after numerous times, it turned out that he was hitting the volume down button instead of volume up. Just to be clear, if you do flash recovery, you will definitely trip knox, at this time there is no way around that.

I understand the skepticism. Yeah, I tried the button combination, usb in, usb out. I can power off the device completely only when it is plugged into power. When I hold the recovery combo from power on, the screen goes black with no flashing of the boot logo, looks as if it wants to go to recovery, and then then the boot logo comes up again, but just continues to the boot animation and continues the boot loop, even if i'm still holding down volume up and home buttons. It will sometimes boot up, then freeze after a couple of seconds, and return to boot loop. On rare occasions it will boot up, but turns me to setup like it's a brand new device. I can access everything for about 10 minutes, and then it will randomly restart and continue to boot loop again after that. I tried update/initialization in kies, but it would restart before the downloading and decompressing of binary could finish. It finished one time and then switch to a downloading screen (although it didn't say odin since you have to manually go there) but the update would freeze at 0 percent no matter how long I left the device there. It's all pretty lame ><

[Q] Android won't boot...

Hey folks...I'm running into a problem I was hoping someone might be able to help with.
Earlier today I pulled my phone out of my pocket at work and saw that it was off...I thought that the battery must have died sooner than I thought. I started charging it in the car on the way home and it wouldn't boot up like normal. It would get to the google or "dots" screen and then reboot. I again thought that the battery might just be really low. After getting home and charging the phone all the way I still can't get it to boot up. As of now, one of 3 things will happen...
1-The phone will turn on, get to the google screen and bootloop (usually when plugged in).
2-The phone will turn on, get to the google screen and freeze.
3-Get to the "dots" screen and either swirl forever or eventually reboot and do one of the above again.
I've read some threads where people suggest this is a faulty power button, that doesn't seem to be the case for me though because I can get into fastboot and it won't select anything or turn off without me doing it.
I've used WugFresh NRT and wiped/reflashed android. I'm running out of ideas. Do you have any others?
I was running the stock 5.0.1, unlocked, not currently rooted.
Thanks!

Did you try flashing factory images?

Yeah, that was what I flashed :/

If you can get into fastboot you "should" be able to flash stock images... Obviously this will revert any root and you will need to flash TWRP/CWM recovery after.
I assume you have a Windows PC with fastboot/adb setup and all drivers etc..
- Download latest "stock" hammerhead images (I cannot post links due to XDA rules... so: "developers.google.com/android/nexus/images#hammerhead"
- Extract the .tgz archive contents on your PC into a folder
- Boot the N5 into fastboot and plug USB cable from phone into your PC
- Go to the folder with the extracted files and run the "flash-all.bat" script on Windows
**Hopefully at this point your device will start to respond.. I.e, on fastboot screen, at the bottom you will see "writing" or something, as the script runs on the command window on your PC.**
If this works, you should be able to reboot once complete and then wait to see if you can get back into your phone.. then you can fastboot again and flash custom recovery, and then whatever rom.
If however you have a hardware issue (i.e, even after the above process it fails) then I am not sure what you could do... I guess ensure it has a complete charge. If you can get into fastboot and the buttons are responsive then it should not be a faulty power button.
Hope this helps :good:

Have you tried a simple factory reset? Reason I ask is it was working fine so sounds like something needs "flushing out" clear cache etc.

Did you choose the right model and firmware before you flash in WugFresh NRT?

The above could be right, however when I've used it, it's pointed out if I made that mistake. Having used his software dozens of times I've found it will bring any Nexus 5 back to life.

Hello! I am apologize for that I didn't read the OP carefully. This happened to me once in that particulary way, but it was immediately after flashing. OP says that it happened suddenly, without reason. So now I am the one, who doesn't read, right? Sorry for that.
Regards, Zagor

Thanks for the responses, but I'm still having trouble.
I have been able to successfully write the newest stock android 3 times (1 without full wipe, 2 with) and the phone still can't boot up and goes through one of the three issues above.
I've also been able to get to the system recovery from the bootloader and I've tried wiping the cache and doing a factory reset from there and the problem remains.
I'd contact google, but I bought it at launch so I don't think they'll do anything for me since it's been 1+ years.

Sounds like you have a bad nand sector. From fastboot try:
Code:
fastboot oem lock
Then reboot into fastboot and check if it's locked or not. If the device isn't locked your emmc is corrupt and there is nothing you can do. If that is the case call Google and they will most likely help you out with a RMA.

I was actually able to relock the phone.
Luckily I called google and they're going to send me a replacement.
If anyone else has any other ideas, I'll still take them...I'd rather not be without a phone for the next week!

You won't be without a phone - they are sending a refurbish unit to you , putting a block on your credit card and waiting for you phone to arive at them. Once that happens they will release the funds.

bootloop and no recovery

Good day.
Thanks fore reading my post.
I had root on my phone like for 3 or 4 months. everything was great and all. I did not dwell in any ROM installing or playing with the firmware.
But I am not sure what I did that this happened.
When I restarted my phone, I experienced everything until the Logo faded to the rotating circle(loading). And it stays there. Always.
I did check on many sites and it seems to be a bootloop. I tried going into recovery, used every button combination possible(I have only 3 and also tried and for my phone and for others to work) and I can't.
It just continues normally and to the position I explained before.
I have a Vodafone Smart 4 Max and even though I want the fix for my phone, I know there are other users that also experience/experienced this problem on different phones.
Might there be a way to fix this?
Thank you for your time
EDIT:: I managed to enter in recovery mode and tried a hard reset of the android. The situation is still the same, the bootloop remaining

Go to bootloader and flash factory firmware with fastboot

I wish I could. I have no idea how to access the bootloader(as I see no function like that).
I only have 4 options:
1).Reboot system now
2). Wipe Data
3)Wipe Cache
4). Recovery from back-up on SD (which I am stupid and don't have)

How did you get to recovery? Wasn't it through bootloader? I found the information you get into bootloader like this: (power off) press and hold "end call"+"power on"+"volume up". If it doesn't work try the same but with "volume down". I guess you tried it, but you never know (plus I've got a feeling you can flash new rom with option 4 you've got there)

Hm, I know what you are saying. For me to enter in recovery mode though, I needed to do the following.
1). Fully shutdown the phone for like 30 seconds
2). Volume UP + power button until the first logo with android appears
3). Let the buttons go and I enter
The problem is that adb and fastboot don't see my device at all. I have been tweaking with the drivers for so long, thinking that may be the cause, but I have no results.
And I can use the backup thing to flash a new rom? It requests an update file though, not an image(a zip file)

I think this is about your phone, maybe it will point you in the right direction:

Help! Can't figure out how to re-enable root

Okay, so! Greetings all.
Back about a month ago, I successfully rooted my phone with KingoRoot, flashed TWRP 2.8.0, and installed Crdroid 7.1 Nougat for my D850.
Now, everything was fine and well, besides being one of the very unlucky users to have their phone stop being a beautiful piece of technology and, instead, become very burdensome and aggravating. It would require a battery pull, sometimes two times back to back (if it would soft reset on first pull and get stuck in boot loop), about once or twice every 3 hours, to as often as a few times an hour.
So, I tried something new. I went back to LineageOS' website and looked through the other D850 releases(all of what, 3?) and settled on the AOSP 7.1 ROM.It seemed like it'd be a great idea, having everything functioning and not having to deal with battery pulls every day. Now my phone is practically nonfunctional, as it doesn't receive cell service and can't read SIM cards.
Needed Information:
-Phone is an LG D850, running a (nonfunctional) custom AOSP 7.1 ROM
-Phone seems to lack root access, and can't be One-Click rooted as is (Haven't been successful with any one click program yet)
-Phone is also lacking in recovery (Tried to access via adb, manual hard buttons, and neither worked)
Now for the actual question: What can I do to make my phone function again, whether I have to reinstall my backup of my previous fail (thus requiring TWRP and root) or just get it back to a truly stock ROM?
Thank you all for your time and consideration. I'll check back in the morning.

Warning: I am no expert, in fact I'm barely a noob, but one thing I do well, and that is I always do a backup. That being said it appears there are two paths to salvation. Get your recovery working or go back to stock. If you installed a recovery but can't get back to it try shutting off phone then pressing power and volume down simultaneously. When logo appears release buttons and then immediately press both again. It will offer a decision screen where you use vol up/down to select. Choose yes on both, (it will not reset the phone as indicated). This should get you into recovery, from there you may be able to flash the needed rom, gapps, root, etc. My suggestion is to load the needed files onto your sd card beforehand. If this fails there is the downgrade via LGUP. This is pretty nifty. I had to rely on the expertise of a Mr. Heyelton and his post, https://forum.xda-developers.com/showthread.php?t=2785089. To my knowledge the POS known as the AT&T d850 can only be rooted at KK. Mr. Heyelton's guide can get you there. from there you can stay with stock, upgrade to a higher stock (?) or proceed to root, TWRP and rom the phone. Don't forget to upgrade your modem, https://forum.xda-developers.com/att-lg-g3/general/modems-collection-d850-21r-20f-10d-t3213856.

Hey man. I wanted to say thanks for pointing me in the right direction. :good: :highfive: I managed to flash it back to stock, and I'll just figure out a different rom to go with. As far as fixing the issue with the recovery not coming up, I have no idea. It was just messed up, I guess. The phone wouldn't go to recovery even after selecting yes both times on the factory reset screen; it would just go black and a red+blue notification light would pop up. Was weird. Managed to get it to stock though, so it's better than it was. Thank you!

Samsung S6 Boot Loop

Hi,
Apologies if this has been asked before, but I've done a relatively thorough search and I can't find a solution to this problem.
I have an S6 (SM-G920F), It was playing up for a few weeks before this, not charging well, and what not, thought it was a cable/hardware issue. Then it stopped working entirely. Initially when it was plugged into the wall it would say it was 91% charged, but if you tried to turn it on it would turn off, and reboot into the charging screen.
I've done quite alot of reading and I've ended up flashing it with Odin (I have a single .md5 file, which i've loaded onto the phone via AP) using the most recent FIrmware UK EE for the SM-G20F. This was successful, however now it only loads the Black screen with white text Samsung S6 powered by android screen and then goes blank and back to the white text screen.
I downloaded an alternative firmware (the one previous version), but this has had the same effect. I've tried to repartition with odin, but this fails.
1.) Is there anyway I can fix this?
2.) If not Is there anyway to remove files whilst in downlod mode?
3.) If I cannot fix it or recover my data, is there anyway to wipe the data securely from my phone so I can sell it for parts?
At present, I can't access recovery mode, only download mode. But whilst Odin communicates with the phone in download mode, I can't seem to access my files from explorer?

1. I would say you'd have to clear cache, immediately after flashing the firmware with Odin, but to do that, you'd have to get to Recovery Mode first...
Why can't you get to it? Does it just start trying to boot nornally? Because if so, it's just a matter of timing it. What I do is... hold power+home+voldown to get to the screen that asks me if I want to get into Download Mode, I press cancel, and immediately start holding power+home+volup until I see the bootsplash screen, and release the power button but keep holding home+volup, and it gets me to Recovery every time, even when I have difficulties such as this.
2. Not that I'm aware of. BUT you could flash TWRP with Odin, and if you then can manage to get to Recovery, you just need to plug your phone into a computer, and your phone will show up in the computer as a device/disk and you can freely remove stuff from it.
If... IF this were to work, I would suggest downloading a stock-based ROM and flashing it. It's far more likely to work properly and bootup without issue than the firmwares you can get, and it's far less much of a headache to do.
3. Nope. There are apps that can wipe data securely (such as Shreddit which does it according to military standards), but it can't be done from Download Mode. There may be some script that could do it in Recovery Mode, but I doubt it.
I mean... technically... you could flash TWRP, go to Recovery, move to your PC all the stuff you want to keep, select the wipe option in TWRP and then transfer randomly generated data from your PC to your phone until it's full - there are many apps that can generate such data. It's not something you could pass off as very very secure, but it should suffice.
I seem to always keep going to trying TWRP - so, you know, give it a shot.

Thanks for your reply! So after flashing it goes straight back into the boot loop. Weirdly if its plugged into my laptop it spend about a second or two on the "Samsung Galaxy S6: Powered by Android" screen before plunging into darkness and shortly after repeating the same message. However if I plug it into the wall it spend over twice as long on that screen before repeating the cycle. It never goes any further.
I've tried your suggestion about perhaps its timing for recovery mode, but even if I go straight from cancelling download mode to trying the power, up and home key it doesn't go to recovery. I've tried a variety of timings both plugged into my laptop and plugged into the wall to no avail. If the phone isn't plugged in, it literally won't do anything whatsoever, won't even hint at turning on.
So Next I tried flashing it with TWRP via Odin and nothings changed, exactly the same bootloop and I still can't get into recovery mode.
I'm starting to think that sadly this phone my be beyond repair! Thanks for your help though, much appreciated.

Hi! I usually run out of my bootloops like this:
try this:
1: go to download mode, and press Power + home + volume —
2: As soon as the screen turns black, continue pressing Power and home, quickly release "volume —" and press "volume +". This will get you into recovery mode.
It always worked for me, so I wish the same for you. Good luck! (And sorry for my bad english)

Hi Vinicius,
Thanks for the suggestion. Unfortunately it didn't work, I even tried flashing it back to a standard ROM from TWRP, but it still didn't do anything, just back to the Samsung logo and the loop continues ever more!

Hi, I have this problem as well.
Originally I had TWRP and root flashed into my phone but for reasons I needed to remove root.
So I followed the Odin route stated here "Mobikin how to remove root from android" (I can't post links but this should be the top result when googling)
However I didn't know if the recovery/boot should have went into AP or BL on the Odin menu and googling didn't give me any answers so I may have tried both....
Right now I tried flashing TWRP and I can't seem to boot into TWRP as well.
I was able to get into recovery mode but clearing data/cache didn't fix it for me.
EDIT: I managed to flash in another stock rom and it boots into the SAMSUNG logo but gets stuck there. I already went into recovery mode to delete data and cache partition but it still doesn't boot.

Same experience. For all those 6 years that I used this device, the wifi was okay until now. It (wifi) is very buggy (turning on and off, and sometimes won't turn on at all) so I restarted the device, then bootloop happens. I flashed the stock rom via odin and clear data and cache. But it is still bootlooping. I think this is the sign that I need to replace my phone IF I couldn't find a fix to this.
