[Solved] stuck on bootloop, can't get into recovery mode or download mode - Galaxy S II Q&A, Help & Troubleshooting

Had a problem with my htc one m8, so i pulled out my i9100 backup phone.
it had neat rom 4.1.2 on it, and everything was working fine.
i have tried to flash onmi rom():
1. entered recovery mode
2. backed up CWM to external SDCARD.
3.flased "CWM-KitKatCompatible-i9100.zip" & rebooted into new recovery.
4.installed "omni-4.4.2-20140214-i9100-INFECTED.zip".
5.installed "pa_gapps-modular-micro-4.4.2-20140207-signed.zip"
6.installed "UPDATE-SuperSU-v2.46.zip".
after that, when i wanted to reboot, i got a message saying i could loose su and if i want to fix it, i choosed "NO".
device entered to a boot loop.
i tought no biggy, i would go back to recovery, flash philz CWM and recover my nandroid backup.
it will not get into recovery mode.
tried again, pulled the battery, put it back, hold down VOL-Down+home+power button, and nothing, boot loops over and over again.
tried to get into download mode, not going there as well.
connecting to a pc with ADB+samsung drivers, the device wont show up.
Any suggestions? did i bricked the phone forever?

Are you sure that the phone doesn't boot into the download mode(Vol Up+Powe+Home) ??
If that's the case, then I'm afraid that your phone is hard bricked forever. You have to fix/replace the motherboard then(about $50). You can go to the service center and get it done, or check out this video(JTAG METHOD): https://www.youtube.com/watch?v=zN7le4GmxZs
I hope something works out for you.

yes, i'm sure :'( its not my first time with the device.
i have ordered a usb jig from ebay, maybe it will force the device into download mode...if not... :\

just got my USB jig i have ordered from ebay(less than a dollar), plugged it to the phone, and it got into download mode!
used odin to flash stock rom, and then installed cyanogenmod with the cm installer.
everything is working fine!

I know this is late, but I wanna ask a question. Firstly I'm happy that your bricked phone came back to life(like how many years ago).
Can a USB jig work on any other phone brand other than Samsung phones? Can it be used for tecno, infinix, and all that? Or it is dedicated to only Samsung mobiles?

Does it boot into recovery mode?
Press Volume UP + Home + Power keys until recovery menu appears.
If yes, then try to wipe cache (and Dalvik cache), fix permissions and reboot.
If that does not help, you may have to wipe data (do a factory reset).
If recovery mode does not work, then your phone seems to be semi-/soft- bricked.
You will have to get the phone connected to your PC in download mode to repair it.
Here is the correspsonding thread about hw to fix a soft-bricked phone => http://forum.xda-developers.com/showthread.php?t=1457458
Good luck !
i have gotten it into download mode but my computer does not see the device
Install samsung kies?
have that installed, reinstalled, and i installed all the drivers. it was working but after the odin flash failed i couldnt get it to connect. right now im building a jib for the phone.
so built jig, now im sad..... it did nothing, now either i have to send it in or some one might know a way to fix it

[Q]S3 bootloop, no recovery nor download mode

I'm using v40 of temasek unofficial cm11, Boefflea version 11 kernel.
while I was using my phone, the phone suddenly went into a reboot and started the boot-loop, even when I pull the battery out and put it back in it starts booting immediately and goes into the boot-loop , whenever I try to go into download mode or recovery mode, once or twice I will be able to reach it, but 3 seconds in, it restarts and goes into the boot loop again (I can't choose between restarting or going into download mode)
would a USB jig help me getting into the download mode or will it be 3 seconds in and restarts?
would a service center help me retain my data as I need them?
Thank you.
momentarily I've managed to be able to access download mode and the laptop started making a sound trying to identify the device, too bad the battery fell off (or the phone restarted) lol
anyways I still need help because I couldn't get into any of them
If the phone starts the moment a battery is inserted then usually the power button is stuck -try giving it a wiggle, or get it replaced.

yeah will do that once this gets fixed lol ..
for some awkward reason, I found out that once I pull out the battery I can use download mode
what should I download?
I tried flashing CWM but I get back to the bootloop ... should I install a newer bootloader?
No, bootloader is irrelevant to firmware. You would be best to flash a full stock rom with odin then factory reset and see if it will boot. I would suspect the power cycling may have caused partition problems if recovery got wiped.

which would mean I would lose all the data in the previous cm11 right?
I'm trying my best to flash a recovery but I think it got wiped for good.. I'm trying to flash it over and over again .. (I unplug the battery once I'm in download mode to prevent the sudden restart) .. before I flashed the CWM through odin I was able to go into a glimpse of a recovery mode, now I can't seem to see it at all...
is there a way to just copy the data (mostly pictures) through odin or adb with my phone current state?
Google says it might be possible

only through recovery mode or hoping your phone would suddenly connect after many boots lol
I don't think that will be my case .. oh well
as long as I can get my phone working again
going back to stock rom didn't fix the issue. can't access anything yet.
any help?
if anyone is reading this, I've been looking everywhere for a stock rom with pit file, I think that's the problem I'm facing since I have different bootloaders and different modes, somewhere around that I jacked my partitions and I think this would help putting it all back
I've found ones for android 4.1 but nothing of 4.3 .. since I came from 4.3 stock rom and then 4.4 kitkat temasek I think 4.1 won't help me at all
time to go to a service center I guess.
OK this is weird...
after I gave up I put my phone on a recover firmware that for some bizarre reason brought it back to life!!! I just put the phone back and left .. 5 hours later it was on and working.. I was able to access the phone for a brief moment.. but for some reason again I wasn't able to get the touch screen to work... I was able to raise the volume.. restart the phone.. but nothing on touch screen..
then it went back to the dead state...
any ideas?

[Q] Stuck at Samsung splash screen - Need to backup data

The phone was working fine until the battery was empty. I tried to charge it and turn it on, but it's stuck at the Samsung logo splash screen. Holding the power button only restarts the device, so to turn it off I'll have to take the battery out. I don't know how to fix this, and if a factory reset is the only option, I need to backup my data first which I currently don't know how to either (without accessing the OS).
I've got to the Android System Recovery 3e menu and tried clearing cache, which did not help. The option to do a factory reset is also there, but I need to backup my data first, and I don't even know if this will fix the problem.
I'm also able to enter download mode.
When connected to my PC it detects an unknown device named 'samsung_android", and it shows up in adb. I've tried doing a backup through adb, but it wanted me to unlock the screen to accept the backup, which I could not, because I'm stuck at the splash screen.
Is there anything I can do to save my data? Anything through adb? Install root (never done this before)?

Hey mate, can you get into the recovery mode? Try flashing the TWRP recovery and boot by pressing power button + home button + volume up and find an option to mount your USB storage via USB cable and see if your phone's folder tree is available from the Windows Explorer and hopefully you can backup your data by then. Just make sure you have all the drivers ready.
Hope that helps.

Yeah, I can get into recovery mode. But how do I get the TWRP to my phone? Do I have to put it on my external memory card and then load it from there?
And I could only find it for a S2 Exhilarate SGH-i577 device. Does it matter if my phone is a S2 GT-I9100?
I've never rooted my phone earlier. Is a root necessary to flash a ROM?

Correct. Put the TWRP zip on your external and flash it normally via recovery mode such as CWM not the android 3e recovery. Or find an odin flashable zip for yoyr device.
I am very sure there is one for I9100 because I ran into the exact same problem before and managed to figure it out. You just have to search for it can't give you a link because I'm on mobile now.
You need to root your phone in order to install a new recovery such as TWRP/CWM or even flash new kernel and ROM.
Good luck.

[Q] I-9300 bootloop and no recovery

Hello,
I have a S3 which is stuck in a bootloop at the samsung logo.
when i turn it on it shows the logo for some seconds then the screen goes black and the logo re-appears.
i can not boot into recovery mode, but download mode is working without a problem every time.
i tried flashing stock firmwares with odin and also tried kies emergency firmware recovery. the flashing always went without any problem, but it had effect. whatever i try, i am never able to boot into recovery and still stuck in the bootloop.
in some tries after flashing the screen just shows the samsung logo forever, but after rebooting it once it then is stuck in a bootloop again (shows the logo - screen goes black - shows the logo...)
i also tried flashing TWRP and CWM via odin, but again i can never boot into recovery mode.
what should i try next?
thx alot for any helpful comment

You can Try this:
1.) Pull out battery
2.) Put it in again
3.) Press Vol up + home + power
4.) When the Samsung Logo appears let it off
I think you press the Buttons too long.
I had the same problem!

i really tried everything, it's not working. btw with i am stuck at the very first image, where it says "samsung Galaxy sII GT-I9300".
i dont think it's just the way i press the buttons because i can reach it on my s1 and s2 without a problem, it's just not working on this device.
could some setting like "nand erase all" in odin help? in other threads there is sometimes mentioned that the internal file system might be screwed up and in those cases a simple odin reflash does not help anymore...
Nand erase will usually hard brick it. Try the rescue firmware from general forum, sticky thread. Follow the guide exactly as it includes a pit file.

thx, but i already did that (multiple times) and flashing via odin always succeeds. then the phone reboots and is stuck at the first samsung galaxy s.. screen. twice i managed somehow to get into recovery (after flashing cwm6) but it then randomly rebooted.
and i dont think that the power button is stuck because when i am in download mode it is perfectly fine it never reboots itself unexpectedly.
Had a similar issue on my tab2 p3100. It all happened when I tried flashing a custom recovery from rom manager.
A bad flash of anything related to recovery or bootloader could be a probable cause.
I remember a knowledge share on one of the threads describing this issue and as mentioned on it all I had to do is this:
1) switch off the device and plug in the charger. This would light up the display showing you the charging status. The status has to show if at least your bootloader part of the phone is fine.
2) plug out the charger and immediately press the three buttons (home + vol up + power) get into recovery mode. This step has to work and help you get to recovery mode.
***Note : the interval within which this step has to be performed is too short since the display would turn off immediately as soon as you plug out the charger. A bit tricky too so you have to be fast. If this misses getting you into recovery, pull out the battery and put it back again. Repeat step1 and 2 again.
3) upon successfully getting into recovery, perform wipe data, cache and select reboot phone from option available on recovery again.
Allow the device to boot. This could take a while since you have performed a data wipe and may prompt for first time set up.
I was able to restore functionality on my tab after these steps and like ppl learn from their mistakes, I then learnt that recoveries and bootloaders are things that needs to be done with a pc only.
Worth a try if you have tried other alternatives and found no go. may help. Who knows..
all the best.
thats also not working. i tried to get into recovery since two days now...
i also tried the steps from this thread: http://forum.xda-developers.com/galaxy-s3/help/solved-pit-bricked-dead-problem-gt-t2535367
but again, after i flash the cf-root (successfully) the phone does neither boot into recovery by itself nor can i do it by hand...
its crazy... in download mode i can see the model number (GT-I9300) and i thought as long as the model number is there and i can enter download mode there should be a way to recover the device.
but i cannot think of anything to try that i have not done yet
If the rescue firmware didn't help then it looks like the emmc chip is damaged.

is there a way to make certain of this? how can i tell if it is really a hardware damage and not just a software brick?
i just dont want to let the phone go, it looks still so shiny
is there anything else that could cause the phone not booting into recovery mode after flashing custom recoveries?

Same here, still didn't found how to fix it.. I guess our motherboard just died..
Howewer I have a solution that "almost" worked for me.
Get a stock firmware in odin and turn on Nand erase and T-flash
When it's done phone reboots and you'll see just "Downloading..." mode when you turn it on.
Then got to Kies and Select firmware recovery...
Enter s/n and model name and wait for the flash to complete.
With it , I got past boot logo and actually booted into android but the phone crashed because I guess I have a memory issue..
Well , gl. If you don't find anything else helpful , try going with this method..

[Q] Help ? Bricked Tab ? GT-P3110

Hello, I was trying to reset my tab completely and I wiped EVERYTHING. I have CWM version 6.0.1.0, My tab gets stuck on Samsung logo screen. It can go into recovery but nothing else. I was told that the reason it won't boot is because I deleted the rom and there is no rom for it to go to. When I try to mount it, it doesn't show up...I've tried to install CWM 6.0.4.6 zip from external SD but installation gets aborted. PLEASE HELP I NEED MY TAB BACK ! Also it shows charging when it's turned completely off...

When you say mount it do you mean trying to send the files over through ADB or just mounting the SD card or putting it into download mode?
If its the ADB issue, try to put your tablet into download mode by using the volume key and power button, then download odin and its stock firmware and flash it using odin. Your tablet should restore to factory defaults using that method
If its the SD card then use the method above as it sounds like recovery may have lost it a bit
If you can not put the phone into download mode (which i doubt is the issue you may want to think about a USB jig as they sometimes get past those issues but from your description I doubt its a hard brick as it gets to the logo
2 things you can try!

I really new to this, i mean writing to help people, so don't flock me.
First, you say your device still have the recharging lights on when shut down, it tells me it's not only a software error, but some short circuit has happend.
Have you tried a hardreset? search google for your model if you doesn't know how.
From what i can read you still have the CWM Recovery, so download Android-SDK and try flashing the recovery from ADB (Found in platform tools.
Last but most tricky, if nothing helps, you' have to disassemble your device and temporary disable the battery, them press and hold the start button down for 5 sec to remove the poweroverload, reassemble again and try ASB adain, you can't reinstall the recovery directly from the SD
