[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

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.

Sensors not working on Ze551ML deluxe after update to android 6.0.1 beta

All sensors stopped working after update to android 6.0.1 on my zenfone 2 deluxe
Google chrome is not working too

Backup and try a reset. Might solve your problems. It did a few after I upgraded mine.

I tried soft reset in recovery mode applying wipe data/factory reset. Is that necessary to wipe cache partition ?

I would wipe data, cache, art and system and then reflash mm.

I did wipe cache wipe data .
factory reset and sensors remain without work

Mine too

Unfortunately it's a known problem with the initial (leaked) 6.0.1 beta. Some phones are not affected (my Z00AD , for instance), but many others definitely are.
No clues as to why, sorry..

Rebooting on stock and stuck booting on custom

Hello
I have a Galaxy Tab 4 7.0 SM-T230 that is not booting correctly.
I got it in a non working condition, kept rebooting when turned on.
I reflashed the stock ROM using Odin after installing TWRP but this would results in the tablet getting to the choose your language screen then restarting itself.
I tried the below versions of the stock ROM but they all have the same result:
T230XXU0ANG3_T230SER0ANG2_T230XXU0ANG3_HOME.tar.md 5
T230XXU0ANJ4_T230BTU0ANJ2_T230XXU0ANJ4_HOME.tar.md 5
T230XXU0ANK3_T230BSE0ANK1_T230XXU0ANK3_HOME.tar.md 5
StockRoms-Series_T230(NU)+V1.6.3
The custom ROMs I have tried get stuck on their startup/boot screen.
I have also tried:
Wiping all david, cache, data, system, internal.
Re partitioning using DEGASWIFI_HIDDEN_100M.pit
Using Odin 3.9 and 3.12 with the md5 file in the AP section
TWRP openrecovery-twrp-2.8.0.1-degas and TRWP_2.8.7.0_EUR_VERSION
The custom ROMs cm-v13-degaswifi-kids-unofficial-20170713, ACHERON_ROM_V2.3.5_SM_T230_NU and [KK] [SM-T231/T230/NU] + Android 5.0 Lollipop Material Design
Combinations of reflashing, factory reseting, cache wiping.
Kies recovery but it will not maintain a connection, keeps disconnecting the tablet
Fixing partitions in TWRP
The only thing left to do as far as I am aware is to NAND Erase all but I am not sure if recovering after doing that is feasible.
Update: Tried Nand erasing, then re partitioning and reflashing of stock firmware, no change.
Tried EFS clear and Phone bootloader update.
Now the partitions appear to be broken and re partitioning with the pit file and reflashing does not fix it, cannot mount data or system.
Any suggestions to resolve this issue?
Thank you

Wipe-/Data and Factory reset doen´t work

Hi,
My s7 got a little bit strange so there very heavy lags.
After this I decided to try a cache wipe.
Aftrerwards I thought i going on the over to the factory reset and this will fix everything.
BUT still it didn´t worked and the reset failed
The output looks like this:
E:format_volume: make ext4 failed on /devblpck/platform/155a0000ufs/by-name/US
Data wipe failed!
Afterwards I reinstalled the OS several times with ODIN.
Still stuck in a Bootloop and a factory reset brings up the same error.
Even a nand erase aswell as a repartition with the correct pit file leeds to the same error.
At the moment I guess the phone is dead and there is no more help.
Or am I wrong and there is a way to bring this back to live?

How did you wipe the phone? You can wipe with twrp and also with adb.

I wiped it with the standard recovery delivered from the Phone.
I tried to flash it a couple of times with odin but still ran in to this error..

Try wipe it with adb. Can you boot into stock recovery? If you cant wipe, make sure you are flashing the correct csc for your phone. So it has to be explicitly for your region and network operator.
