Go in recovery and wipe the caches and data factory reset and reboot. What recovery do you have? TWRP 2.6.0.0 causes issues for some users. Try flashing Philz Touch recovery from here http://forum.xda-developers.com/show....php?t=2281367, download the .tar file and flash with Odin 3.04 in downloadmode.

No, just flash with Odin without a wipe.

1.Pull out the battery, reinsert it after 30 seconds and boot the device into CWM Recovery: Volume Up+ Home + Power keys simultaneously.
2.Go to “Advanced”
3.Choose “Wipe dalvik-cache”
4.Now go to “Mounts & Storage”
5.Choose “Wipe /cache”
6.Reboot your phone
The bootloop should be gone now. If it still persists, do this.
1.Boot the phone again into CWM Recovery
2.Now go to “Mounts & Storage”
3.Choose “Wipe /data”
4.Choose “Wipe /cache”
5.Then reboot your phone.

If these steps don't help. Check if the rom is really for your phone. Redownlod the rom and flash it again. I tight be a corrupt download.
Also what version of cwm are you using? I read bout older cwm versions not going well with 4.3 Roms.

My suggestion is that your read through the forums here as there are several "beginner guides" that will get you started.
After you installed your first custom rom the process proves itself to be easy:
- Flash a stock ROM (2.2 nordic)
- Acquire root using SuperOneClick
- Instal Clockworkmod recovery/2ndInit (I prefer 2ndInit)
- Transfer the nandroid backup (.zip file) to the root of your SD card
- Reboot phone when led turns blue hit volume down
-Wipe data
-Wipe cache
-Wipe Dalvik (It's under advanced)
-Restore -> select update zip from sdcard
- Browse to the nandroid backup file you put on your sdcard in step 4
Done

[Q] Reboot when wiping cache partition in stock recovery

When selecting the 'wipe cache partition' in stock recovery, the system reboots after a couple of seconds. I think it used to return to the recovery menu. Is this the same for everyone else?
Running stock 4.2.1 unrooted.

Yes, mine does that as well.
It never returned back on this phone. it can stay in recovery after a cache wipe if using CWM or TWRP other than that no. But theres no need to stay in recovery if using stock, so its helpful after wiping cache. Other custom recovery yeah because it has other features..

4.3 flashing and bootlooping problem

Hi there
I seem to have a problem flashing 4.3 roms, actually any rom that isn't stock in general.
Right now I am running syzmel's 20E with 1.3ghz overclock version 3.09.
Back to the problem: this is the steps I take to upgrade to any rom: 1. Download (slimbean, vanir asop) 2. flash v20D (unmodded) 3. Root it using Framaroot 4. Install CWM using L7CWM.zip (extracted, then clicked on flash bootloader, flash recovery, and then booted into recovery) 5. Boot into CWM 6. Click on factory reset and reset 7. Go into mounts and storage and format /system 8. Go to advanced and wipe dalvik cache. 9. Flash either 4.3 version slimbean or Vanir ASOP (tell me which is better) 9. Flash gapps (Slimbean: Slim AIO minimal Gapps, Vanir: 4.3 minimal Gapps which is found in the Vanir ASOP page) 10. Factory reset again 11. Wipe dalvik 12. Reboot
Now as soon as I reboot, either it stays rebooting, or boots once and when you reboot it stays at the boot loading page (slimbean logo, or android logo) (In other words, once you go black, you never go back. Not being racist, just saying once it blacks out it doesn't work no more). So i retry. And then I give up and stick on v20E.
So please suggestions?

Are you sure it wipes made ​​correctly?
Danm, yes I'm sure.
Why you dont format cache and data & data/media ?
Did you try boot without gapps... Sometimes bad gapps cause a lot of problems

When you factory reset it clears cache automatically. I'll try without Gapps.
wipe data,wipe cache wipe dalvic cache

[Q] Flashing various TW Lollipop fw over existing CM12 fails

Hello,
actually I'm using a SGS4 I9505 with cm-12-20150304-NIGHTLY-jfltexx and CWM 6.0.5.1.
I've tried to flash several TW Lollipop firmware wich i found in the I9505 forum:
1. Kushan+Touchwiz+Lollipop+Lite+Rom+v.1.2
2. S4_Echoev42_EchoePop2_020315
3. OA7-2.1F
4. XXUHA07-v2.01
Before flashing any oft this firmwares i made a factory reset, wiped both caches and installed the modem Firmware via Odin.
After flashing firmware # 1 and 2 my phone was stuc in a bootloop (only Samsung Galaxy S4 Logo appears).
Flashing firmware #3 and 4 fails and cwm reports error 7.
Flashing cm12 afterwards isn't a problem and runs fine.
I think the wipe fails or doesn't work properly. Is it enougth to select factory reset in cwm and wipe the dalvik cache manualy?
What can I do?
With besteht regard
Mirko (NemesisMF)
What if it is a recovery problem?
Thought about that too.
Should i try twrp or philz?
I switched to Philz Recovery and flashed S4 Echoe Rom v42 without any Problems.
CWM seems to have a problem to falsh TW Lollipop images ower an existing CM12 an the I9505.
You need to do full wipe not just cache.

As I wrote above I did a factory reset before flashing and wiped the caches with cwm. If that is not enougth it would be nice to explain what else I have to wipe or post a link.
While using philz recovery the factory reset for clean system is enougth and the new System is working fine.
Factory wipe is not full wipe, you need to do a full wipe as in format to install new rom, phillz recovery has this feature can't remember exactly where, I think its under advanced.
Just have a look in the sub menus.
Just to explain it better when you do a full wipe it deletes every part of the existing
Rom including the system, data and cache and some other stuff completely removing the android operating system, so unless the rom you install does a wipe before install parts of the existing system will remain and can cause boot issues. For example as you've already discovered you are trying to install a tw rom over an existing cyanogenmod 12 installation which Will cause it to hang on boot.

Do you mean a factory reset from within Android itself? If so, then that's a complete obsolete step. When before flashing a rom you should perform a factory reset, then they always mean a full wipe from the recovery. You need to do a full wipe from the recovery. That means the /system partition is being wiped. You will see it in the screen during the wipe if it wipes /system.
But it also could have been a problem of CWM. I don't think it is being updated anymore, so better use TWRP or Philz.
