Hello, everyone!
I have a R730 model and it started to reboot in loop. I tried to do a factory reset, but it lasted a few minutes an then it keeps rebooting again. I tried to put it in Download mode, but it lasts like 15 seconds and then it turns back to reboot.
I don't know if it theres any chance to revive it.
I've searched over the forum and I didn't find any case of bootloop even in download mode. Any suggestions?
Thank you in advance.

The unit has been used for about 2 months and remains quite new. It was quite stable before. Yesterday night, about half an hour after plugged in for charging and with WiFi Hotspot turned on for sharing 3G data to another netbook, the unit suddenly rebooted itself. It then stopped at the start-up screen and remained there for several minutes. I kept holding the power button for a few seconds to turn it off but it then automatically reboot itself afterwards, and stopped at the start-up screen again. It means that even complete turning off is not possible.
Trying to enter into recovery mode showed the following few lines:
# MANUAL MODE #
-- Updating application...
Copying Common Apks.
Click to expand...
Click to collapse
and then it automatically rebooted again. It means that it can't enter into recovery mode normally.
It was possible to enter into download mode. And it was the first time this machine went into download mode. I run Odin Downloader and flashed the official stock ROM. After showing "Pass", the device rebooted itself. Unfortunately, it still stopped at the start-up screen, just showing "Samsung Galaxy Tab 7.0 plus". It is really troubesome. I have experience playing several Android devices before and it is the first time I face such troublesome problem.
The device is an official product. The biggest problem is that the original purchase invoice was lost and most likely that I couldn't get official support, repair service or replacement.
May I ask if anyone would kindly provide me some help or advice. Thanks!
Instead of going into download mode go into recovery mode and see if there are any errors. Your scenario is sounding very similar to the one I had in the past.
I just ran into a nasty snag at boot logo as well. nandroid, stock kernel and factory reset were no help. Try Odin back to Stock, it still may not get past boot logo, hold vol up and power to get into recovery and factory reset. Hope it works for you.
Unfortunately I was unable to get into recovery mode even after odin flashing stock ROM.
It rebooted itself a few seconds after displaying some lines of text. I can't see the normal recovery menu.
ok people...in need of help.
back story, my phone has been force closing and freezing frequently, but this is not unusual with this model phone....infuse 4g AT&T....i would have to restart my phone at least 4 or 5 times a day. that's not why i'm posting though... last night around 4am i used my phone for the last time before i went to sleep. it had 100% charge. today when i woke up it was on the samsung logo. i tried to restart for like half an hour trying various methods, hard boot, taking out battery, etc. nothing. still on samsung logo. then i tried to enter recovery and wipe/format.... kept getting an error...all options chosen kept giving me a fail to execute message. last resort, i tried to restore to stock using odin. i did this twice, first time with the re-partition checked (it got stuck), second time without it checked (worked, installed stock rom but still stuck on samsung logo) third time with re-partition checked and it got through the installation just fine, all passes all green lights. phone still boot loops but now not at samsung logo, at "rethink possible" screen. i try to go to ui menu before booting and i cant, it just takes me to recovery where none of the options work. i'll upload the screen that i get when i try to install or select any option. any help appreciated!

Hello.
2 days ago I did factory reset to my phone and since that day it stays stuck on boot loop when i try to turn it on.
I tried to flash it with a lot of firmwares, nothing works.
This morning i tried to start it, i succeeded. It worked good until I entered on Google Play app. In that moment the phone stopped.
Now when i try to turn on my phone it stays stuck on boot loop [1 hour already].
I need help.
Hi guys, so recently I bought a Galaxy S6 Verizon off of eBay. I got it for fairly cheap because it was stuck in a boot loop. I usually have no problem fixing stuff like this, but this time is different. So the first thing I tried when I got the phone was to do a reset and cache wipe from recovery. I rebooted the phone and it showed a screen that said "Android is starting, optimizing app 9 out of 31." when it got to 21 the phone rebooted and went back to 9. It did this several times before I attempted to wipe/reset again. I then downloaded the tar file G920VVRU4CPH1 and flashed it in Odin. I did a manual reset before the phone booted, and it is doing the same thing again. reboots to a green screen where it tries to optimize apps, stays there for about 20 seconds, and reboots over and over again in the same cycle. I have tried all other stock marshmallow roms that i can find, Odin won't flash older ones, (assuming its not letting me downgrade). Also another weird thing, every time I flash, the blue update screen goes to 32%, stops, erases, and reboots. Phone is on 6.0.1 version MMB29K.G920VVRU4CPH1 as seen in recovery. Any help would be gladly appreciated. Thank you!
I am having a similar problem with loading new rom. The farthest it gets is 32%. Sometimes it doesn't get even that far.
I ended up just buying a trashed s6 and swapping the motherboards. Only way I could fix it
Hey guys,
Sorry if the answer to this found somewhere else, tried searching but foud nothing for my situation.
My buddy, who is a super basic user and was not attempting to do anything with his phone, has a G4 that suddenly stopped working and went into a boot loop.
We tried factory resetting it and it got about half way through the apps before stopping, going back into a boot loop and was unable to get back to the same point in the factory reset.
I tried flashing the ROM using LGUP to H811-20o and it said that it went successfully on LGUP as well as the phone itself, but after it rebooted it went back into a boot loop.
Now the boot loop goes faster but is still looping and we cannot get back into download mode to try again or potentially try a different ROM. It goes to the first screen of download mode with the 5 blue dots but doesn't get past that, I've removed the battery waited for a while in between attempts and still nothing.
We can get to the factory reset screen and click yes, it will then go to the green android guy with his cog wheels exposed but then immediately goes back into a boot loop.
Any help is appreciated, even if its just a confirmation of being SOL.
