[Q] Galaxy S2 Soft Bricked after root....

Hi everyone!! New here, but not new to Forums in general. I searched around and couldn't find my exact issue, so I figured I’d start a new thread. This is gonna be kinda long, but I wanna give as many details as I can to keep things accurate.
My wife and I both have the Galaxy S2 T989 (T-Mobile). Both purchased like new off eBay. When I got hers a couple months ago, as soon as I got it I factory reset and wiped the caches, upgraded to JB via Kies, and then turned right around and rooted it via Odin using the instructions found on galaxys2root.com. Everything went flawless, took me less than a half an hour total for everything. I got mine a couple months later and did the exact same process as soon as I got it in the mail. However after rooting on Odin and getting the green pass just like hers, it got stuck in a boot loop when it rebooted. It would go as far as the "galaxy S2" splash screen, and sometimes past that to where the Android takes off, then reboot, or freeze. It then became unresponsive to any button pushes and I had to pull the battery to get it to shut off (The battery is a new OEM Samsung battery incidentally). I ultimately had to unroot, re-install ICS and re-upgrade back to JB via Kies again to get out of the loop. I did this whole process 3 times to make sure it wasn’t something I did. So I’m still running unrooted with JB on it now.
The only thing I noted that was kinda odd was that when I open Rom Manager in my current non rooted state, it shows that I already have CWM and TWRP installed on it. Even though when I go to recovery mode it's the standard OEM Samsung menu. I never installed TWRP, and CWM was only on it for a bit when I was in the boot loop. Could this be my issue? Are they both still somewhere on my phone interfering with each other and I can only see them via ROM manager?
Sorry for such a long first post, and thanks in advance!

hi,
can 'be that your device has some residual old. Do as you have advised. install a stock rom and firmware, so it becomes a new cell phone. After odin starts TWRP (much better) and root.

I would flash a complete bone stock Rom using Odin and start over. Also rom manager was highly discouraged on the AT&T version of the s2 so I don't know what the stance is on T-Mobile's version

Thanks for the advice! Should i flash it back to ICS then try to root again via Odin before i upgrade back to JB? I'm guessing there's something that isn't getting wiped. Since i can run CWM and Root with Odin without a hitch. it's the initial reboot after all that is done that I go into the boot loop.

Sorry for my ignorrance, what exactly is TWRP, and is it now on there because i used Odin and it installed it automaticly? And do i want to use this vice CWM?

One more question...before i try all this, can i backup everything on Kies just like i would be able to with CWM and reinstall if my root fails again? I've only used Kies for firmware upgrade, never to reinstall a backed up copy of my phone.
Thanks!

Hi
TWRP and the 'one touch recovery, better than CWM.
The backup kies can not recover from CWM
steps:
install odin, after recovery, nandroid backup, ROM, and root.

Flash the stock firmware using odin!!..it will work!

freezes then booted
Hello I have this problem with my galaxy s2 i9100. After reboot the phone wasn't booting something like "boot loop" so I re flashed the firmware and now the phone boots up but after the boot it freezes immediately. So I decided to install clock work mod recovery and install cyanogen mode 11 with cyanogen mode the phone boots up and are able to be used again until the screen goes to sleep mode or the power button is pressed then the screen goes black and doesn't turn on after long pressing the power button it reboots. So I don't know what else to do I have tried kernels, operating systems re flashing reseting and nothing helps. No need to tel me to do resettings. Also my galaxy s2 i9100 chip has insane chip bug but I don't know if it has to do something with my problem.

(sOLVED) my note is stuck on Samsung boot screen!!

i upgraded my note N8000 via odin mobile pro with success and everything was smooth and the root was not intact
I tried to flash a theme via mobile odin but was not success, but note was still ok
then 2 days later I tried to enter the recovery mode , i found the note stuck on samsung boot screen and dose not reboot, I can enter download mode but can not enter recovery mode to reflash even the stock rom
what to do?
should i reflash the CWM as 1st time? then reflash the root if i found it is gone?
or i have to reflash the stock rom first via odin desk top since i can not reboot the note? problem is the stock rom is on the note and do not have it on PC
the note now is on Samsung boot screen, how to turn it off since note can not remove the battery?
EDIT 1::good:
Flashed a stock recovery via odin desk top, and rebooted
Note is back alive , no wipes, every thing still there, root still here
Rebooted once again with success
rebooted into recovery (stock since I lost my CWM) with success
EDIT 2
Flashed CWM and my note is back for my modifications
:fingers-crossed:

Will reflashing the tablet to stock, delete all of my files off of it? Is there a way to retrieve the files through download mode somehow?

It says you flashed a stock recovery. Is it the same case for a stock ROM?

sorry, my mistake, flashing the stock rom will not delete your stuff, just be sure to flash the same rom or higher, not lower one

So, I tried flashing the stock recovery and that did not work. And then I tried flashing the stock rom (multiple times with different roms) and that did not work either. My tablet is still stuck on the screen that says "Samsung Galaxy Note 10.1". Do you have any other suggestions?

can u write some details about what was before and reason for problem, to think together about a solution

My Note 10.1 N8013 was rooted, had TWRP, and Cyanogenmod 10.2 Nightly on it. I hadn't touched it in two days and went to turn it on. It wouldn't turn on, so I assumed it was dead. I charge it overnight and try to turn it on in the morning, but it just goes into a boot loop. The tablet says "Samsung Galaxy Note 10.1" and stays that way until it dies. If I boot into recovery mode, the Teamwin (TWRP) title screen pops up and then immediately disappears. The tablet then shows the battery loading icon if it is plugged in. The icon shows up, then disappears and the shows up again and repeats this a few times. I could only boot into download mode successfully.
I have tried flashing different stock roms and recoveries through odin, including the one that you have linked on here. None of them have worked. I have also tried repartitioning the tablet, which passed on Odin, but did not solve the problem.
Other forums say that I should do a factory reset or wipe the data, but I do not know how to do this without being able to boot into recovery or the OS itself.
Thanks
P.S. I also brought it to Best Buy to see if the Samsung guy could reflash the stock rom, but his rom did not work either. They are all passing on Odin, so it isn't an error in that case.

I read that a lot of people got problems with Cyano roms. I did not like it and never used it, sorry can not help you

Could it be because of the Cyanogen rom? I didn't update recently... I probably updated it a week before it died. Would you happen to know how to do a factory reset / wipe the data from the tablet, if I can't get into recovery mode or the OS?

I don't think that there is any other way, sorry about that.
try to put your problem in the Cyano rom thread, may others had the same and solved it

Ok thank you

Let me know if you get it fixed
Hi kyleschepis,
Let me know if you find a solution. I have a very similar issue . . . the difference is, I am not using a custom ROM. I have the stock ROM that came with the GT-N8013.
My issue started about 5 days ago. My Galaxy Note had been having occasional issues with the external SD card. A warning would appear saying that the SD card had been removed, and a couple of seconds later it would re-mount and every thing was fine.
But 5 days ago, I picked up my note and turned the screen on (it was already started) and noticed the warning message while the screen was still locked. Then, as the second message was still being displayed letting me know that the SD card had been mounted, I swipe the screen to unlock. But instead of unlocking, my Note completely rebooted. It got as far as the logo screen (displaying "Samsung Galaxy Note 10.1"), but would go no further.
I am able to get into the Odin download mode but cannot get into recovery mode no matter what I do/
I have tried re-flashing the stock ROM ("KIES_HOME_N8013UEUCMI3_N8013XARCMI3_813049_REV00_user_low_ship.tar.md5") several times, as well as trying to install customer recovery modes like CWM and TWRP, as well as the stock recovery. But the power + volume up combination does not get me into recovery mode. Even if, as many have suggested, I continue holding the button combination until the logo screen displays a second or a third time.
I have been without my Note for 5 days now, and I use it for everything. So, any help I can get would be appreciated.
Thanks,
Rob

I have the same problem. I was just playing a game when it suddenly turned off and went to the boot screen. Also tried installing N8000XXUDNE5_N8000OLBDNE3_N8000DXUDND1_HOME.tar.md5 (success but also didn't work). Still stuck at the "Samsung Galaxy Note 10.1" screen.
Also can't access recovery, or do a wipe before installing firmware (I think USB debugging isn't turned on).
Did you find any solutions yet?
Thanks.

[Q] Need help galaxy s2 i9100 boot loop and freezing

Hello I am searching for help. The problem is that my galaxy s2 i9100 stopped working properly. It started like this maybe I took out the battery or something I don't remember and then I turned it on the phone wouldn't boot. I thought maybe my android operation system got bricked so I decided to re flash it but as I can remember the phone wouldn't go in to download mode but some how I managed to reflash the firmware but then phone booted it just froze and then I pressed lock button the phone screen would go black and reboot. After installing cyanogen mode 11 the phone would boot and it could be used again until pressed the lock button it would go black and reboot so I have been reading forums and found problems like boot loop corrupted mmc or something else corrupted and I don't know what the real problem is because the symptoms are like boot loop or corrupted mmc or soft brick. I have already tried other kernels other android versions clock work mode

I have found that my emmc has the insane chip bug. The phone boots normally with cyanogen mode 11 but then it goes to sleep mode or I press the power button the screen goes black and the phone restarts. I have tried siyah kernel to try dual boot but then I flash siyah I cant get into recovery.

I think you should flash latest STOCK ROM with Odin, and then follow available custom rom instructions on xda...
Test if the stock rom will work for you, boot your phone etc... Try to use it a few days. If everything is OK, proceed with
further procedures...

I have already tried this but with the stock rom phone boots but at the section where I have to chose language I jus freezes stops working

So I think it is a hardware problem. Phone on stock rom shouldn't freeze on language selection. Something is wrong. If you are on warranty, let them fix it for you, if you are not, try to fix it in some phone repair point. I'm sure you can stop your attempts. It will not be better for now.

You have flashed the kernel for the edge not the flat. Flash a flat kernel and it will start working
You should be flashing rom for g930 not g935.

J5 2017 boot loop

Hey. Not sure if I'm asking for help in the right place. I'm new and I made this account because I'm getting kind of desperate, so I'm sorry in advance if I'm posting in the wrong place.
I just installed TWRP onto my Samsung Galaxy J5 2017. I thought it all went pretty well until I tried to reboot it after checking out the custom recovery only for it to be stuck in a boot loop. The regular J5 logo comes up, then the screen goes black, then the logo comes back up and so on. I am still able to go into recovery and download modes and I've tried using the TWRP recovery to wipe and format all data, but to no avail.
Upon some researching, it seems that flashing the official firmware using Odin is one possible fix, and I am currently downloading it from Updato, though it is a slow download and it will take all night. Even so, once it's ready, I'm not entirely sure how to flash it or whether I need any extra files to make it work, since I haven't been able to find any guides for this phone specifically.
If anyone could confirm that I'm going down the right route and guide me through it, or suggest some other, more effective, fix, I would greatly appreciate it.
Thanks in advance,
Mayo

Well, I flashed Magisk and that seems to have fixed it
