[Q] Galaxy S2 GT-I9100 wont boot up after flashing new ROM - Galaxy S II Q&A, Help & Troubleshooting

Hi guys need help if posible, i was flashing new rom Litening_Rom_v2.8 but now nothing works and phone wont boot up im am still able to go into download mode but when i flash diferent version of rom i still get the same problem can anyone help please

Try a different rom, see if it boots up....then wipe everything n try flashing again

Flash stock rom using Odin.
Wait 3 4 minutes, takes time to first boot.
Still bootloops, remove sdcard.
flash any cfroot and right after go into cwm.
Format data, system, cache, sdcard.
Now flash stock gb using Odin.

Help, cannot flash through odin, it keeps failing

BEFORE anyone mention that this problem has been mentioned before, read twice.
i was on omega rom, it kept rebooting. so i cleared cache and all that stuff. shut down the phone, booted in download mode. tried flashing my stock firmware KK3, it goes up to flashing kernel then fails.
when i turn the phone off and on i get the a different screen saying firmware upgrade failed try restoring via kies.
i tried lp2 firmware it flashes fine. could it be that i was using ICS before and now it doesnt let me go back to 2.3.6
pls respond with solutions
Omega has ICS themed ROMs but no ICS firmware ROMs so it wont be cos of that.Did you try a full system wipe before the flash??
boot to recovery and wipe cache partition.Then go to "mounts and storage" and format System/Data/Cache and then do a factory reset then reboot.The Phone probably wont go past the Galaxy-S logo so pull the battery then put it back in and boot to download mode and try the flash again.If that doesnt work you could try to flash the F/W that works and then flash a new kernel.After that try the 2.3.6 flash again.

Thx I will try it soon. But how come I can flash ics kp8 and lp2 roms
Are you using the new bootloader then?
That one Im not sure of but I have read on other threads that people have had to "repartition" their phones to be able to flash back from ICS.Not bieng on ICS I dont see why you cant as the Omega ROM was just themed.Im on the latest Omega and its 2.3.6. so 100% positive it wasnt ICS.Also Try stupid things like another com port.Happened to me once.The one I was using when I had an i9000 stopped letting me flash it via Odin when it reached the same stage every time I tried.Dont Know why.Just had to change ports.Try everything:
1.Full wipe and flash.....If that dont work then...
2.Flash F/W that works then change kernel and flash old bootloader(as mentioned above)never know,might work.

Flash it in PDA in Odin.
ALso you could try a program called "Fus Downloader"

True.Same thing happened to my mate.He has an i9000 and Odin stopped flashing his phone but only if he used a PIT file so I gave him my i9100 cable and it started flashing his phone again with PIT file selected.Weird how things work sometimes for no real reason.Anyway Nandroid backups are always a good call.could have saved some trouble the this case.Ive got a Nandroid backup on my phone and copied to DropBox thats months old but it would get me out of trouble if this sort of thing happened to me Even though its old as.Gotta have that saftey net.

Mate,thats a strange one alright.
Any luck yet.I was thinking that you might have to look for a package that has the older 4 file flash with pit.Its possible that maybe you need to repartition your device.Might be hard to find thought.

[Q] Problems Installing Roms

Hi I have Rooted my GS2 Gt-I9100 running 4.03,Using CF Root. Everything OK. I put the Zip File of Miui 2.6 on my SD Card went into CWM Recovery did all I was told and the ROM seemed to Install.,when Finished the Miui Logo came up and thats as far as it went.I then tried to use ODIN 1.85 but I could not get a .tar file out of the download. What am I doing wrong ????. Is the CF kernal not compatible with MiUI or CyanogenMod.. Sorry If I appear Stupid....
Using cwm format cache data system sdcard(not micro sd)
Now flash same miui using cwm.
First boot takes time.
Still issues, download the ROM again
Just go into cwm and wipe data, cache and dalvik. If this doesnt work , reinstall.
But usualy the firste boot takes some time ( can take up to10-15 min)

Stuck on samsung bootscreen

Hi, i followed this tutorial to root, and wanted to flash this rom.. So i wiped data/factory reset, wipe cache partition, format /system.. and now when i reboot, i'm stuck on the samsung galaxy tab 10.1 boot.. did i bricked my device? I want to flash the rom but i cant get my pc to recognize my device as i have not get past the boot screen :crying: so i cant put the rom in the device and flash the rom from clockwork recovery..... :crying:
Of course its stuck. You wiped everything but did not flash the ROM. *facepalm* Either find a way to sideload the ROM to your tab through adb or reflash to stock using Odin.

No, you should put your ROM zip in your SD card, fullwipe, and flash.

Can't flash ROM past 4.1.2

I'm pretty sure flashing a stock ROM will fix this but as my download of the huge stock ROM failed after over an hour I thought I would ask.
So I have been running stock CM10.1 for a long time and thought I would update to kitkat, really want to try ART.
But any ROM I flash that is over 4.1.2 does not boot, tried twrp and clockwork. Done a complete format from recovery of all partitions, and waited over 5 mins for it to boot first time.
But when I flash CM10.1 phone works fine.... Really annoying me now.
Any ideas before I start downloading the epic Samsung files again?

Try this.
May be it will work
Flash kk compatible kernel first
Don't reboot the system
Boot into recovery
Wipe cache
Wipe dalvik cache
Format system
Wipe data
Install required zips
Reboot

Humm..... Will try flashing a KK kernel first and see. Didn't think of that, normally there included with roms but it can't hurt thanks!

Bugger also just noticed I put this in S2 not S3! Sorry guys! Still going to try KK kernel first though.

[Q] phone stuck in recovery mode and won`t flash zip file

hi there!
i`m using a i9300 running on s5 sensation v6 rom on boeffla kernel v6. using touch cwm v6.0.4.6
i was attempting to do a full wipe (format data etc.) and reflashing the sensation rom due to some issues.
while fomatting, the process suddenly stop and my phone rebooted to recovery.
i thought i was done formatting. when i flashed the zip file, it suddenly switched off and rebooted to recovery mode.
i tried flashing the file or wiping/factory reset again and again and it continued rebooting into recovery mode.
any ideas on why this is happening??
