Should i flash PAC Rom through TWRP before flashing Stock Rom through Odin?
Help will be appreciated. Thanks

Status Update.
I managed to boot but i am greeted with
"Storage Damaged"
The data partition has been corrupted. You need to reset your device to factory defaults. This will erase all your data
/data is also set to exFAT should i convert it into ext4?

Do we have guides such as this?

Factory image wont boot

I flashed the latest 4.2.2 factory image from google. but it wont boot. stuck at ''X'' boot animation. I can access bootloader. I have tried several times but no luck. it still stucks at boot logo. then i flashed team win recovery and tried to install a custom rom(xenon hd stable 6.0) by pushing rom files by adb. But unfortunately recovery cant factory reset or wipe the cache. it fails. and even it fails to flash the custom rom zip file. Now i have fallen in a completely stupid situation. Please somebody help. Before flashing i was in xylon rom with twrp recovery. Before that i had cwm recovery. But I thought flashing factory image will completely wipe everything. But I cant figure out why it is happening. Please help.
I figured out something ! I have flashed CWM 6.0.23 recovery now. and it says it cant mount anything. I think there is the problem. What can i DO ppl?
Flash the stock recovery and clear cache.
Solved
Solved !!
At first I tried all types of ''mounting sd card'' process in adb. none worked.
Finally
in CWM recovery > Mounts and storage > format /data and /data/media (/sdcard) [ not to be confused with the full ''format /sdcard'' option ]
and it worked. Thanks BTW

[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.

Cannot wipe with TWRP

Hi,
I have G935F, installed TWRP 3.0.0.0 and rooted, WITHOUT wiping. System boots correctly, but I cannot do factory reset or wipe with TWRP, because I got some messages like "Cannot mount Data" and "Failed crypto loader". I understand that it has to do with encryption. Can someone please enlight me, and give me tips about the issue?
Thank you

You have to download dm-verity and force encryption disabler from here , put it to SD card, reboot into TWRP, FORMAT DATA (not wipe) and flash that file (dm-verity and force encryption disabler). All your data will be erased.
No way to unencrypt without loosing you data for the moment(
"All your data will be erased" means that after boot I'll find a clean system installation (as factory reset)?
I hope not to be posing stupid questions, I'm completely new to this world
Thank you very much
Yes just as a factory reset

No, you cannot perform a backup, because your data is encrypted by default and the only way to disable it is to format your data.
I have a unique problem. I have a HTC Desire 612 from Verizon and I decided to revive it to playe PoGo. But it was stuck in a boot loop and I couldn't get any custom ROM.
Finally a gentle soul here gave me the stock rom and I flashed it vide TWRP and played PoGo for weeks. Then yesterday the phone bro led and when it came up it was stuck in a boot loop.
So I decided to flash the stock ROM again. But before that I tried to factory reset. I could go to TWRP, select wipe data, enter yes and the wiping was successful, then clear dalvic and cache and system beforehand finally I flashed the stock ROM.
Surprise surprise is NOTHING happens. The phone boots without the apps telling me they are installing. Then I get back the exact same data in my phone including my selected wallpaper and apps. Before I can do anything the phone restarts.
Point is wiping and restoring the stock ROM does NOTHING to the phone yet the processes are successful. Can somebody help?

You need to wipe the data partition in TWRP in order to decrypt it.
wipe/format data/type YES
TWRP doesn't yet support samsungs encryption.
wiping data will obviously remove everything, so backup first.
immediately after wiping data, flash an updated supersu, or dm-verity disable
Flashing a rom over an encrypted data partition will do nothing to solve it unfortunately.

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
