Hey Guys,
I have a big problem. My Xperia T is rebooting permanently. All i can see is the Sony Logo. I had downgrade it to 4.1.2. after that i rooted it and installed CWM (with CWM6-cDM_v2.2-DooMLoRD-Xperia_S-JB). After that i did a wipe data/factory reset and then a wipe cache partition and a wipe dalvik cache. Then i tried to install the custom rom but the installation was aborted. Then i wanted to reboot the phone. CWM asked me to fix root. I only pressed yes and since then the phone keeps rebooting. What can i do now? I have still warranty but isnt there a simpler way to get it work?

Hi,
I wiped my dalvik cache through CWM but now I'm getting into a bootloop, so I restored a backup of my NAND-Flash to get the cache back and then it works again...
Why is that so? Do I have to do anything else to get it working?
I wanted to wipe the cache cause I have some strange problems with Fearkill's edition, so I hoped that this will solve it...
Thanks

any other suggestions?
Have Same Problem Brother
mee too got same problem any help would be appreciated..!
How long did you wait. I found that after installing a new rom or factory wipe that it would take up to 5 minutes to boot. It would just sit at the samsung logo with a pulsing glow for ages.
Maybe you just need to give it more time?
What tools and packages did you use?

Wipe cache, do a factory reset, wipe dalvik cache. If still stuck, it looks like a bad flash/kernel problem. Try flashing it again.
Finally succeed
It's work for me, I simply entered my galaxy S3 into recovery, make factory reset, wipe chache and then reboot and my S3 finally boot normally. Thank You all.
Make my thorough wipe as below when flashing a new ROM:
1) Wipe data
2) Wipe cache
3) Wipe dalvik cache
4) Format /system & /preload
5) Format internal sdcard (make sure you save anything you need before)
6) Flash ROM
7) Wipe cache again
8) Wipe dalvik cache again
9) Reboot
This way you ensure you flash your new ROM in a completely clean environment. Then when booting the new ROM, wait some time before saying it's stuck at the boot logo. As people already said, sometimes it takes a long time to display the setup screen (but should be less than 8 minutes in any case). I'm assuming you have CWM to do this; if you don't, try the equivalent in the stock recovery (but it doesn't have all these options), poweroff, boot in download mode, then flash using Odin.
ATTENTION: make sure you make the wipes using a brick-free kernel! Search the forums if you don't know what it is. If you don't, you may brick your phone. You should flash a brick-free kernel before anything, without any wipes (it can be done through Odin if you download a safe kernel in this format); then you are ready to go with the wipes and flashing a new ROM.
my j500h keeps on restarting just after displaying samsung logo. i have tried nearly everything but seem to be stuck on the same bootloop. any idea am so stressed up.
I've majorly screwed up. I'm using a samsung galaxy ace s5830. After partioning my sd card I found that I couldn't root my phone since cwm was not allowing it. So I got frustrated and did a factory reset. Now my phone will not get passed the samsung intro and the blinking samsung sign. Please help
Reflash a rom with odin, it will wipe anything wrong (just remember to wipe data, wipe cache, and wipe dalvik cache)
Thanks will do so. can you shed some light as to how a simple factory reset got me into a boot loop

After wipe data/factory reset, bootloops can be solved by wiping cache and dalvik cache.
If something got messed in the kernel while trying to flash the root zip, then wiping everything will still keep an error, maybe that's what caused the bootloop, this is fixed with a fresh odin flash.
Check that your root zip is compatible and thay you use the correct recovery to flash it (sometimes it must be done through stock recovery, sometimes through cwm)
Hi. My galaxy s3 4g I9305 OPTUS AUSTRALIA. has been rooted cwm installed. I have tried to install Xtreme.v6.1 and supreme rom 5.0. Neither would fire up after multiple attempts. I have wiped delvic cache, cache partition, wipe data/ factory reset, battery stats and fix permissions.
both roms load (flash) sucessfully then I get the samsung reboot screen and after that a pulsing samsung logo which stays for hours. can any one tell me what I may have missed? Flash is done via cwm install zip from sd card.

Try to do the 3 wipes...
I would try TWP recovery, as big as CWM is I have found many bugs and such with it and so far absolutely zero with TWP. Is it giving you any errors when trying to flash via CWM? Read the text because it may just be warnings and install anyway. There are also logs you can upload (go to advanced settings I believe)

Yea, Try this recovery : http://forum.xda-developers.com/showthread.php?t=2140681
I have Xperia Z3c 5.1.1 rooted with locked bootloader. It is on wifi only. Yesterday I've turned wifi on and suddenly have got device off. I tried to reboot. I see the Xperia logo and bluish Xperia start screen with waving elements. However, the home screen and apps are not appeared, have just black screen. The battery is fully charged (green led). I tried several times reboot today as well with the same result. I believe the phone is soft bricked.
The phone is rooted with NDR Utils and TeamWin Recovery (TWRP). I also have Titanium backup.
After reading this forum I found several ways to unbrick the phone:
1. Soft reset (Power + VolUP) up to 1 vibration.
2. Hard reset (Power + VolUP) up to 3 vibrations.
3.Use flashtool (flashmode) and flash ftf file. Should I flash Kernel as well?
4. Use phone System recovery (Power + VolDown).
Which method I should try first? Can I save root and my current Lollipop firmware or I should go and start from the scratch with rooting and flashing 5.1 again?
Thank you for your suggestions.
Try soft reset and hard reset. This don't break your phone but it is worth a try. If this will not work do NAND backup (full backup of phone) in recovery. Now you can try clear cache in TWRP (wipe -> advanced wipe -> check cache -> swipe to wipe). If this don't work try clear dalvik/art cache.
If this metods didn't work flash same rom (if rom was't pre-rooted root after flash). If system starts you can restore NAND backup without system partition and cache.
If system don't start after restore backup the last chance is clear rom flash.
I don't know where the problem is but in my place I would do that
Thank you krzysiek546 for your help.
I have tried soft and hard reset, both unsuccesful. I made backup and wiped cache and dalvik from within TWRP. The phone after apps optimization has started the system (there was black screen but I was able to see home and Back buttons, which were non-functional, i.e non-responsive.) The screen became black again after a few secs and did not return to the life then.
I think I'm going to flash the Rom. My question is there is any chance to get brick again in case I will restore from the TWRP backup (if there was a virus or something?). May be I should wipe data, cache and dalvik and only then made a backup?
Also, when you saying "a clear rom flash" as a last chance do you mean factory reset?
Thank you.
Don't wipe data before backup. This is like doing backup after format system. It doesn't make sense.
Have you tried this metod with flash with nand backup and flash same rom (zip from twrp or ftf from flashtool) and restoring data without system partition (it's important)? In this i mean something corrupted system files. In this metod you can save your data. You just reinstall system and restore data from nand backup.
When I sayed "a clear rom flash" i mean wiping all data in recovery and flash rom from flashtool or twrp without restoring anything. You can do it first. I think now it's beter because you can check did that fixed your problem and if this "clear rom flash" repair your problem you can restore data from backup.
As to your question. Yes you can get brick from restoring data from twrp but in my opinion this virus or something must have root permissions to do this.
After installing the newest supersu, I also get this bootloop. Is there a chance to undo this without wiping data?
Edit: ok, after hard reset, flashing SU, cleaning caches etc. (which all did not help) I reflashed the ROM, now it works again. Pheeew.

Try to install SuperSU v2.81 - author apologized for inconvenience caused regarding 2.80 update. I got this bootloop too and solved it by installing SuperSU v2.81.

When I had that error, it was still V2.80 and no update round the corner.
Thank you for the link. Worked great for me. Installed per TWRP.
Well, in my case I didn't updated SuperSU, just have turned on wifi. I think the problem may be in Wallpaper app I have installed previously. It changes wallpaper every day, but I noticed sometimes the background of my home screen where all apps are became black.
Anyway, only "clear rom flash" with wiping cache, dalvik and data helped me. I then installed pre-rooted Lollipop ROM I made before and restored all custom apps from the Titanium backup. BTW, don't try to restore system apps from the Titanium, I've got the error with Xperia keyboard and have to make a restore whole system from TWRP.
Thank you krzysiek546 very much for your help.

I also got bootloop after installing latest SuperSU from Google Play.
How can I install 2.81 (or 2.79) when phone is in bootloop?
