Bootloop - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I was trying to revive an old Samsung Galaxy S II (I9100). The thing had a LineageOS-ROM installed that didn't quite work properly.
To start over, I flashed the most recent stock firmware I could find. According to Odin, the flash was ok, but the device is stuck in a boot loop now. On power on, the screen "Samsung Galaxy S2" shows (the old yellow triangle is gone), then a boot jingle is played, then a blue Samsung-animation starts. After a while, the screen goes black, and the animation starts over, but the first-start screen is not repeated, and the sound is not played again.
Perhaps I didn't flash the correct ROM? Can someone point me to the latest stock download? (SamMobile doesn't seem to have ROMs that old any more.)
Any other idea that I could check...?
Regards

You should wipe data and cache. That happened to me before i did that. Hope this helps!
If not, flash different rom.

here is the JB rom. it works only on intl(i9100) variants of s2

VRUDMI1 Stuck at Verizon Logo

This SCH-I545 is in great shape, almost brand new. When I got it, it was stuck at the first "Galaxy" logo. I tried to flash to MDK, but it failed. So I think it was running ME7. So it came already stuck at ME7 with Galaxy logo.
Then I flashed it to DMI1. It booted through Samsung, Galaxy and large Verizon symbols. Then it got stuck at the small animated Verizon logo. The animation still moves. I tried factory reset from stock recovery, no change. I tried to erase the cache, but recovery never got to it and just reboot.
Last, I flashed the de la Vega for DMI1. It is stuck at the same animated Verizon logo.
What can I do to get this thing working? I care less about rooting and custom ROM. I just want this phone to work....
Anyone having the same problem?
I flashed the phone with the MJ7 Odin tar and reset the phone. The phone is still stuck at the small Verizon screen. I believe after the small Verizon logo, it is the screen with language selection.
What could go wrong here? What else can I try?
Bump.

[Q] Galaxy s3 stucked at logo screen

Hi all.
I´m new here. Speaking from Brazil!
I´ve just got an S3 stucked at the logo screen and I´ll detail all info and what I´ve already done.
The battery was bloated. I´ve changed for a new one.
The animation blue lines around the Samsung word come but the little music starts but stops at the middle. Finally the word Samsung stays at the screen forever.
The phone´s onwer said that the battery was ending very fast and charging fast as well.
And sometimes the phone stucked at the logo screen, but it´s just take the battery off and it started normaly.
What I´ve done:
1. wipe data / factory reset | wipe data cache
2. flashed stock rom with odin 3.09, 3,07 and 3,04
3. flashed an older stock rom with all 3 odim versions
4. flashed clockworkmod and steps 2 and 3 again
nothing. always the same.
I´m wondering whether the battery issue did somthing to the hardware.
Any help, hint, light, pathways...?
Thanks a lot!!
Try the rescue firmware and pit file, search in general forum.
If the phone is shut down unexpectedly then the emmc chip can be corrupted or damage.

[Q] Galaxy S2 GT-I9100 hard bricked

Hi guys, I`m new to this forum and I wouldn`t be posting this topic if I found a solution on other forums. If anyone had a problem like mine, or saw a thread before, I would appreciate if you pasted a link to the solution, or gave some kind of advice.
First of all, I`m new to rooting, custom roms, etc., so I guess that whatever I did, it was my fault. I got this Galaxy S2 (GT-I9100) as a gift, and since i already had a phone, I wanted to take a risk and take a shot at installing a lollipop rom. I watched a few tutorials, it seemed simple enough, so i thought why the hell not, but in the process something went wrong...
Sooo... here is what I`ve done:
1.) Rooted my phone with VROOT
2.) Flashed custom recovery with ODIN. I`m not sure which version of CWM it was, 6.0.4.5 I think (the file is named CWM KitKar compatible-I9100). When I flashed CWM, my phone didn`t boot up. All I got was a Samsung Galaxy logo and a yellow triangle for a few seconds before my screen went black again, but I could still access both recovery mode and download mode using the combination of keys.
3.) And then I did what I think screwed up my phone. I thought maybe flashing a lollipop rom through recovery would solve the issue (maybe the recovery is incopatible with my older stock rom and it`s the reason why my phone isn`t booting). So i flashed CM12 from galaxys2root.com. It`s called CM12.1S ROM for Galaxy S2 GT-I9100 (Andorid 5.1)
Not only it didn`t solve my problem, I still can`t get my phone to boot (now I get a samsung logo and a yellow triangle, but screen doesn`t go black after a few seconds, I left it in this state till the battery ran out and still nothing). And on the top of all things, I can`t get my phone to recovery mode anymore, all I get is the yellow triangle. I can still get it into download mode, but it doesn`t connect with my PC anymore. It charges, but I can`t connect it with ODIN anymore. And the weirdest thing is, when I connect it to PC, my other USB port goes crazy and disconnect my USB Wi-Fi adapter
What went wrong? Any advice is highly anticipated. :good:

Samsung Galaxy Young Duos- Stuck After Flashing S5830M With Odin

Wrong firmware installed
Dear friends i need some help, yesterday i was doing some changes to my Samsung Galaxy Young Duos with Odin Downloader at certain point everything was alright until i got distracted and installed the S5830M firmware on it (It contained only the PDA file) it installed successfully but, when the phone was turning on showed me the boot image, and got stuck there, later it turned off by itself and now only shows a white screen, turns off and turns on again and so on...

Can't get into TWRP, only a quick glimpse of TWRP then back to samsung logo.

I have an old Galaxy 10.1 note 8020. I loaded Lieneage OS 14 with Gappa's 7.1 pico. It became like a new tablet and everything has worked fine for months. Would so update Gapps to the latest, has done this many times. This time on reboot, it locked itself in the black screen with the Samsung text. I am trying to get back into TWRP but I only see its text for a short moment and then again on black screen with Samsung start text. I can connect with ODIN but only get errors when I try to reinstall TWRP.
How do I solve this? :crying:
See attached image of ODIN.
Is this a dead forum?
Really disappointed!
