[Q] Samsung Galaxy S2 GT-I9100 Boot loop (soft brick?) - Galaxy S II Q&A, Help & Troubleshooting

Hello all, I recently had a problem with my Samsung Galaxy S2 GT-I9100, I installed CM11 on it, but It had some bugs, and I bought Galaxy Alpha, so I wanted to give it to my mother, but since she is used to TouchWiz phones, I installed 4.1.2 JB ROM, but device is stuck on boot loop because flash failed? I want to get into recovery, but I have a bit of problem..... , I dropped my phone 4 weeks before this happened, and I replaced shattered screen, but unfortunately I lost power button, and that metal plate is destroyed by pencil I used to lock the device, now I can't boot into recovery, tired combo with download mode reset and vol up + home button, nothing, just samsung logo and boot loop continues, so I tried with adb, but devices recovery is not supported, because I flashed CMR 6.0.5 (that is newest version for GT-I9100) but black screen on boot appeared, so I finally flashed stock rom for the last time 5 hrs ago and nothing, evrything is stock and chache memory also dalvik chache is not deleted, so how can I delete that so I can finally turn device on and set it up? Im not pro\ with Android, just enthusiast so I am mad on myself for doing that, I do not want to waste working device, just how can I delete chache, or can I even fix the phone??

You will have to flash a kernel or recovery that is compatible with stock 4.1.2. Use apolo kernel 4.15 or dorimanx 8.44 v004 and see if it boots up. Look at my create kernel tar from zip guide for pre-made odin kernels.

Stuck on Gtab 10.1 screen

I flashed the stock rom back from the poitee kernel and now every time i boot i get stuck at the Samsung Galaxy Tab 10.1 screen. When i go into cw to try to reflash another rom, it says i have nothing on my tab. how do i fix this or how do i transfer a new rom to my tab without it booting up?
been in the same situation, poitee's kernel is still raw, tab not detected in usb, not charging when off etc. Reinstalling another custom kernel may help, but i recommend restoring from a previous backup or re-flashing a stock rom. There's a backup by pershoot available in droidbasement or try searching under threads "reflash to stock"! Just flashing boot.img is no use as wifi/bluetooth modules have been redirected hence won't run unless a re-flash to stock.
how do i transfer a stock img to the tab when i cant even boot?
You CAN enter download(odin) mode right! (power plus volume down(left) when boots leave power while still pressing volumekey choose right image)! Flash a stock rom from odin.
yes thats what ive been trying to do for like 30 minutes now. it gets to maybe 1/8th of the way done and stops.
ive been trying this
http://forum.xda-developers.com/showthread.php?t=1119492
Finally able to get it to pass in odin. tab still just boots to samsung galaxy tab 10.1 and sits there. This time though, every 20 seconds or so, it vibrates quickly 4 times
Flash a stock rom from odin! unselect repartition, try the [stock][euro][touchwiz] rom in developers section, posted by me! Its stock hence will definitely pull you out. Follow the instructions there! Just follow the guidelines....last night i was in the same shoes, the stock pulled me out. The rom from referred post by you, is not pure stock and is rooted hence interfering with boot!

Boot Loop, Can't Access Recovery Mode

After hours of searching and flashing roms I've decided to give in and start a thread:
I downloaded a jelly bean rom, using CWM, It then preceded to install. Stupidly I didn't opt to factory reset and wipe everything (I thought CWM would take me to recovery mode before flashing the rom). That left my phone in a boot loop. I then flashed a stock rom (4.0.3) but it still was boot looping.
From the past few hours I've spent in these forums it seems by best bet it to flash a rom that has all the parts (phone, csc, modem etc) but I can't find one anywhere. Does anyone know where I can find one or of any way of getting into recovery mode? Any help would be much appreciated, thanks.
Device: Samsung Galaxy S II - UK - O2 (Was running CM9 before I ruined everything).

Hi mate,
The best thing for you to do is enter download mode (hold volume down+home key+power) and connect to Odin and flash an official firmware again
I know that XWLP7 contains everything in the 1 file as this is the one I flashed. Simply place the file in PDA section of Odin.
check out this thread:
http://forum.xda-developers.com/showthread.php?t=1075278
Good luck mate!!
Thanks for the reply. I had tried flashing a stock rom a while back but to no avail. A couple tries later and it worked - I'm now running Jelly Bean but more importantly I have a working phone!
For anyone having similar problems (which seemed to be a few). Just keep flashing stock roms and remove the battery a few times, cross your fingers and at some point you should be able to get into recovery mode to do a proper install. Also I was mistaken about it being a boot loop, I was actually just stuck on the starup, galaxy s II, screen.
But anyways, cheers for your help.

SII Help boot loop

I have a SII i777. I have been testing roms on the phone sense I bought it. I was testing C-ROM for Galaxy S2! [Android 4.4.4/Floating Multi-Window]. I was letting my phone charge. When I went to check the time I noticed it was in a boot loop. I booted into recovery formatted the normal stuff still boot loop. I ran Mr-Cook script rom whip, kernel whip reapplied the rom then the Gapp and then the shift kernel. Still boot loop. Please help i must be over looking something.
I suggest installing one thing at a time to isolate the point of bootloop.
Install i777-omni/slim/shostock (no gapps, no custom kernel).
-if bootloop, flash stock distribution as final test (a weak/damaged battery can cause a bootloop)
-if no bootloop, then wipe again and add gapps, but still no custom kernel
-if no bootloop, then add custom kernel
-etc.
-Cyril

[Q] Soft brick, stuck on Samsung screen, no recovery mode

Background
I've got a SGS2 from a friend that is stuck on the Samsung logo (the one after the boot logo, with the swirl/pulse logo). I cannot get into recovery nor download mode with the volume up (down) + home + power key combination but I do get into download mode with a USB JIG. I am certain that the phone was pure stock and fairly certain that it had Android 4.1.2 on it before I got it.
I followed the
[GUIDE] Fix an unflashable or soft bricked GSII. I used the I9100XWLSD firmware, but I remained stuck on the Samsung logo. I also flashed the Kernel (nothing changed) and the Bootloader (+ Kernel + Firmware again) as mentioned in the thread above, but still nothing changed, i.e. stuck on logo, no recovery or download mode via key combo.
Last thing I tried is the Siyah S2-v6.0beta5 Kernel as mentioned here. Now I am stuck on a 'Android gets updated, Apps are opened' screen.
Questions
What else can I try?
Ideally I would like to get access to the internal memory, because there is still stuff on there that was not backuped. What that still be possible?
If I would get it back to run I would like to put CM11 on it.
Thanks!

Did you hold the button combinations when your phone is off for more than 4 seconds? If you flash a kitkat kernel that is newer and doesn't support jellybean (I know this sounds crazy, but just listen), your phone should automatically boot into the recovery after being unable to boot into the rom. Have you done a factory reset and wipe the cache partition yet? Do that in the recovery and flash the jelly bean kernel again.

Yes, I almost got blisters on my fingers, thats how often (and long) I tried it. Also released the power button but continued to hold vol-up+menu as soon as the boot screen showed up.

Does sound a little crazy indeed, but it also makes sense to add such a feature (i.e. boot into recovery if rom isn't present). Any particular suggestion for a KitKat kernel or should I just pick one of those mentioned here?

Nope, no recovery, ergo no factory reset (or is there another way with a softbricked phone?)
Anyway, that would delete the userdata from the phone as well (e.g. photos), correct? Or are they already gone due to my rom flashing etc.? Oh wait, there is this difference between internal memory and internal usb storage, right?
Update
So I could not decide which one of Kitkat Kernels mentioned here to take. But I tried flashing the CWM recovery files, both GT-I9100_JB_ClockworkMod-Recovery_6.0.2.9.tar and CWM-KitKatCompatible-i9100.tar, with Odin. Flashing went fine, but on boot I only see the bootlogo and then the screen went black.
Any suggestion on what other kernel I could try would be welcome.

The guide which you used for flashing the kernel was for GB and ICS. Now as you have stated your friend's phone is running on JB.
I think you have not rooted your phone correctly but if you have done so try going into download mode thru Usb Jig and install the latest cwm recovery and flash a custom rom (don't flash cm11 directly)

Yes, I realized that I probably used the wrong kernel from the guide, but AFAIK the I9100XWLSD firmware also contains a kernel, so that should not be a problem (i.e. the kernel was flashed again when I flashed the firmware). I did try the CWM recovery (see my edit above), but to no avail, since I does not take me into recovery mode either. (I assume that you mean that I should flash CM11 from the CWM, not through Odin).

Did you do backup of your stock ROM. If you can revert to the Samsung logo where you were stuck earlier (boot animation) I think then I can help you

I don't have a backup of the original ROM, but I can flash a stock ROM and that still gets stuck on the animated Samsung logo.
Anybody else with an idea?

Help - Star GT S7262 duos whitescreened

ok, I', usually pretty good at rooting and such having my galaxy S4 for many years now but I got this Galaxy Star for work just to use it off wifi and bluetooth but it had 4.1 and i needed it on 4.4 for it to work so I knew i needed to root it, load recovery and find an updated rom.
I Odin'd CWM recovery and all I got was a white screen when going into recovery mode. didnt matter what i tried. I wound up flashing a file that also wiped out my download screen, now all I see it a blueish/white screen for download mode, but I can odin files ok.
I've tried every stock recovery hard reset file i can find online and nothing helps. Any help is appreciated. Is there any samsung stock firmware somehere that wipes everything???
Model: GT-S7262
and I seem to have bricked it now, wont even power up after flashing a phillipine version of the firmware.
well, no more white screen but now I have no display at all. still goes into download mode though.

I came from a Galaxy S4 too
You need to flash FireLord1's CWM 6.0.5.1 on stock ROM, otherwise you will get a whitescreen trying to enter.
I know it works with both Indian and Eaten European firmwares.
ok, so i need a link to a the stock rom and his CWM. I can find indian firmware i think.
Weird thing is, I can hear it boot up, Samsung Kies and Odin see it just fine. Just a black screen for everything now.
got it back working with this firmware..
