I just used Kies to come out of a horribly persistent bootloop. When I turn it on, though, it stays at the setup screen. Where you're asked to select your language and all that.
I can rotate the screen for a couple of seconds, and/or use my rocker to adjust the volume and see it on the screen, and can see some messages from my carrier, but can't select anything. Then it freezes completely, in whatever orientation and with the volume bar.
I've taken the battery out and put it back in, factory reset and deleted cache. It still turns on and gets stuck. I don't know what to do.

What specific phone are you talking about? For Samsung phone flashing stock firmware via ODIN will probably help.

Thanks for responding! Yes it's a Samsung (Galaxy Core II Duos; SM-G355H)
Flashing the stock ROM was what got me into that darned bootloop in the first place, so I'm saving that as a last resort.
I'm currently using Kies again. I flashed an unofficial version of CWM to my phone, formatted /system /data and /cache and I'm trying Kies again. If that fails then I'll repeat and use Odin.

I recently acquired a "broken" SGH-T869. Can't boot into recovery, nothing shows up on the screen to indicate a regular boot, etc, but it does boot into Odin for some reason...
So far I've tried flashing ICS firmware and Gingerbread, to no avail. This post says that you need to wipe data to get out of the boot loop, but I can't get into any recovery: http://forum.xda-developers.com/showthread.php?p=23257624#post23257624
So I saw this thread where people were wiping data from Odin. Maybe that would work? But the link doesn't exist anymore:
http://forum.xda-developers.com/showthread.php?p=26484341
Update: I flashed CWM using the heimdall suite, but still nothing boots except download mode. Unless there's some magic way into recovery I don't know about?! I only see a power button and the volume rockers.
Update #3: Everything's fine!
Not sure what happened. I left it plugged in overnight, then later on I noticed the screen was on (but completely black), so I tried the power button to turn it off. Then it booted! Since I already tried flashing CWM I just dropped a new rom on there and wiped everything. Whew.
Wondering what the issue was though. Guess it doesn't matter, but I'm still curious.
I have a question, dont really know where to ask. I have the tmobile j700t, and I've tried restoring with odin, (with the j700t firmware of course) and im not sure if its doing everything. Everything seems to go fine in odin, flashes boot, modem, system etc. reboots, rebuilds cache, then it just goes to my original lock screen with my custom wallpaper and all my apps still on. I can do a factory reset after, but it doesnt seem to do anything but clear the cache. Am I missing something? I enables OEM UNLOCK and USB debugging before hand.
The inability to make write changes sounds like a bad NAND issue, you could try flashing with a .pit file but the phones internal memory could be physically damaged.

Try clicking the Nand erase all box and unclicking auto reboot. Flash the factory ROM and when it completes hold volume down, home and power buttons until the screen goes black. This is important, as soon as the download screen is gone you need to hold the recovery buttons (volume up, home and power) so the phone can erase all system data and update itself the way it's designed to after flashing a factory update. If the device reboots before you enter recovery you have to start over. Hit thanks if this helps bro.

well that seems to have fixed it, weird though, when I rebooted into recovery like you said, it did an update, there was a progress bar, then it rebooted, and rebooted AGAIN, did an "update" and then rebooted. Weird, I usually see it say "updating" but then it will stop and you can bring up the recovery menu. Never seen a progress bar and then it just reboot twice. Well anyway it seems to have worked so thank you!

Whenever you flash back to stock or update a stock firmware through official means, it automatically boots into recovery and erases the system you have in place, very similar to TWRP. If you try to flash a stock firmware without erasing everything you will always run into some kind of incompatible memory error. The screen you're thinking of is just the stock recovery checking your system and OTA's for an official upgrade. Glad I could help man.
I'm really hoping you guys can help me out here. This is an S7 I bought from a Best Buy when I visited the US in 2017, and I got the Unlocked version so I would be able to use it back in my home country. Unfortunately, this is the second time I've had trouble with it in a span of 4 months and the first time it was a hardware problem and ended up quite expensive to get fixed.
Today I was using my phone normally when I decided to use the Google instant translation to translate something on my computer screen. That caused my phone to freeze, restart, and then tell me I was using an unauthorized flash and it was going to be locked, or something like that. Even after restarting a few more times, the phone would never get past that screen. I proceeded to factory reset/cache reset and from then on the phone just got stuck in a boot loop.
I learned that the fix would be to flash the phone. After a lot of work I found the G930UUESACSI1-20190930144640 firmware (the XAA version, for Unlocked) and successfully used Odin 3.13 at the Download Mode screen to flash my phone. It then restarted, went back to the blue screen, started installing some updates, when it was 100% it restarted again. Unfortunately, the loop remained. Galaxy S7 logo first, then the Samsung logo, then it just repeats.
I have also tried turning the phone off with the Recovery screen shut down option (since I can't seem to be able to turn it off with the power button right now), wait a few minutes, then turn it back on. Nothing changed.
Please, does anyone have any insight into this? What else could I possibly try, or what could I be doing wrong? I really don't want to send it to repair yet again in such a short time.
Many thanks in advance.

You need to clear the cache after flashing to get out of the boot loop.
Use the download key combo to restart. As soon as the screen goes black move to Volume up+home+power.
In the recovery menu choose clear/ Wipe cache, then choose reboot.
I apologize for not updating this thread before when it was still recent. The fact is that I didn't manage to fix my phone; clearing the cache after flashing did nothing to stop the loop.
I ended up taking the phone to the people who have fixed it in the past and after more than one month, they gave up. So I got my phone back and I want to try to give it another go before I just sell it for parts.
Unfortunately, my phone has come back even worse. Now it has no Recovery Menu to speak of, at least none that I can access; after a few seconds of the blue text on the top saying that it's entering recovery mode, it then proceeds to a blue screen saying: "Security Error: This phone has been flashed with unauthorized software and is locked.". I can still access Download Mode.
I have attempted flashing a few firmwares that I believe should have worked with my SM-G930U. Odin listed the attempts as "pass" and, after restarting and going back to the Download screen, it says the binary is Official. However, after trying to restart the phone normally, it starts displaying the blue screen again, and then, after going to Download mode, the binary is reverted to "Custom".
I believe right now the order of the day is to get the recovery menu to work again so I can do all the cache cleaning that seems to be required after flashing firmware. Any ideas at all on how I should proceed? Is there something specific I should download to fix the recovery menu?
How many files are you flashing in Odin, is it just 1 file in the AP slot, or 4 files: AP, BL, etc.? Also, is your phone rooted?

Never rooted, was using the phone legit before it froze and entered boot loop. I flashed all 4 files, multiple times.
Someone tried fixing my phone a few days after I replied to this thread and some progress seems to have been made, but now the phone cannot get past a black screen with a "SBL Error! rdx_init!" in red text, and "upload mode" in yellow text. Still cannot access Recovery Mode, but Download Mode still works.
I did a little Googling on rdx_init errors and it seems I need a firmware dump from another G930U or something like that...any ideas on how I can proceed?
Flash it with Eng Boot in all slots using patched Odin. Reboot to recovery and wipe it. Reboot system. Then root it with advanced adb root. Links for all of this are here in xda. Enjoy

Sorry, I'm not an expert at this by any means, I'm not sure what files to get. So far I've found and downloaded the following:
S7_Oreo_Nougat_Adb_Advanced_Root_V10
S7_Oreo_Nougat_Adb_Advanced_Root_V12
S7_Oreo_Su_Binary_Only_ADB_Root
But I had no luck flashing any of these cause my binary is 10. Is there any more help you can provide me? I really don't know how to proceed

I thought I had one in my phone, but I don't. If you look at the thread where you downloaded the Root_V12, you will see it. It's near the end of the thread somewhere.
Hi, it is an older device so you might have experienced everything possible.. so,
After a long time of trying to fix that phones mind, I wiped everything avaible in TWRP
multiple times(got mad). Last thing was data.
That way I went from a bootloop to an active nothing.
Phone does not react to any command, it does not react to USB charging or on PC.
That's the case a few months back, the phone halfway in the trash and I bought
myself a iphone (hate it).
I put the Galaxy S7 on a charger today and it starts immediatly in to TWRP.
From there I tried to install a ROM that's left on the SD card, which forced
a restart into TWRP. Into download mode I managed to install the stock Oreo ROM via Odin.
It went through like a charme, all green. PASS!
The phones screen is black and does not react to any command, nothing.
I had "auto-reboot" activated.
The phone is active it's warm and I'm waiting for the battery to die again, to restart.
..meanwhile,
Can you give some advice please?
Why would the phone have struggle with the boot with stock rom installed.(which has worked before,no updates installed)
When should I install TWRP?
When do I install what kernel?
Last thing running was the LightROM with moro kernel with nothing tweaked.
Also. The issue why i deaded the phone was a camera/flash thing, where I could only take pictures with flash activated.
Front and back camera. On all camera apps, I couldnt scan my ID for banking due to that.
Also on different kernels and different ROMs including the Samsung stock.
Why would that be
Could not accept...

OK so what you've done is correct flashing stock (which includes stock kernal). You have to make sure the stock ROM is correct for your device and region or it will not start.
It's not unusual to have to flash it twice with Odin.
Next up you don't need to wait for batt to die to restart. Press volume down+home+power and keep them pressed until phone restarts. Should now be in download mode, reflash correct ROM with Odin. TWRP is wiped off the phone when you flash a stock ROM.
If it doesn't go through the boot up/freezes/ does nothing etc. You need to "wipe cache" then reboot from the recovery menu.
Press and hold volume down+home+power. As soon as the screen goes black move your finger to volume up (it may take more than one attempt). Once your in recovery menu use volume up and down to move through options and power to execute. Wipe cache then reboot and allow the phone to go through all the reboot stuff. It can take a few minutes just leave it alone. It will also reboot a couple of times.
If it does nothing after 15 minutes then start again and repeat the process.
Thanks for reply.
The Phone was off for a day and after charging for 1h it still does not react to any command. Vol down + home + power does nothing. Same with vol up.
Is there a way to force a boot? Even if the PC does not recognize a device on usb?
I Tried the commands 30 secs each, plugged in and off. Also usb port is not broke since the phone is getting temperature after a while charging..
The phone has completely run out of power.
I charged it up, turned it on. But after I unlock the screen, after a second the interface starts rebooting. That is, not a complete reboot, but exactly the interface, a few times, and then a complete reboot.
I can use the curtain, turn on and off wifi, but until the phone unlocks.
I tried resetting the cache via recovery, it didn't help.
I also put the latest update through odin with save data, that didn't help either.
Really need to save the data of one installed app. Please, if you know what you can try, advise me.
Was thinking of updating one ui via adb sideload in recovery, but don't know how.
