[Q] bootloop on i9506 (ks01lte)

hi!
yesterday i followed these instructions to flash philz touch 5 (cwm base version: v6.0.3.7) onto a fresh galaxy s4 using odin and then rooted it by installing the two zip files in recovery mode. this worked really well. after using my phone for a while, i really missed the pure android experience and wanted to flash a custom rom from aokp. so i made these steps
download custom rom for i9506 (unified version)
make a nandroid backup of the original rom
wipe data/factory reset -> clean to install a new rom
install zip from sdcard -> select the previously downloaded custom rom
unfortunately i immediately got an error that my phone is not supported by this rom, since it is the ks01lte and not a jflte or jflte***. first i thought that's unpleasant but not a real problem since i have a nandroid backup. so i made a normal factory reset and restored the backup i made before. after it was successfully finished, i rebootet the phone. but since then i don't get passed the white samsung lettering after the blueish circle animation.
thanks for any help or tiny hint.
hi!
fixed it by my self. in case some one runs into the same problem:
i flashed the correct original firmware from here with odin. after that it took a while for the first boot and i had constant force closes. after a full wipe in the original recovery everything was fine again. then i rootet it again. now i've to find another custom rom which actually supports my model and delivers the pure android experience without that touchwiz cr...
thanks, kopi

[Q] How to restore downloaded apps from back on different ROM

Hi Guys,
Just a quick question from a rookie.
I like changing custom rom since I rooted my LG G2 about a month ago and experimenting some custom roms on my LG G2 D802.
I have managed to successfully flashed few custom rom such, Paranoid Android, ClaudyFlex 2.4, Liquid Smooth and CyanogenMod. I always do backup on TWRP everytime I have fully restore all my app on each ROM i'm using. My question is, is it possible to restore only the apps that I have previously downloaded via TWRP? as I hate re-downloading again all the apps via wifi that sometimes take a very long time to fully restore from PlayStore.
Let say I'm now using CyanogenMod 11 with TWRP 2.7 recovery installed. I want to change my ROM to Pardus Classic HD ROM. Should I just simply restore from my back up (Pardus Classic HD ROM+Gapps+all downloded apps on .zip file) that I have done previously using TWRP recovery or should I clean wipe and install the Pardus ROM first, then do a restore of backup from TWRP backup folder after the Pardus HD ROM has been fully installed on my device.
Sorry for a rookie question... just enjoy the beauty of rooting devices and so keen to experimenting here and there...
Regards,

Problem with recovery TWRP 3.0.2-0

Hi guys,
some weeks ago I upgraded my recovery from 3.0.1 to last version (3.0.2-0).
I made the upgrade by the official App (downloaded from Play store). No problem at the first look. But some day ago I tried to made an upgrade to my custom rom AryaMod 8.1 to 8.3) and during the flash the device has been rebooted and the upgrade of the rom has failed. The device is ok and all functional. I have thought at an error. Not important in this case.
But to day I have made a good backup of all my data and (after a full wipe of Dalvik, Cache, Data and System) I re tried an change of custom rom with a new one Rom (DarkWolf_FW Galaxy S7 Edge Port][V2]) on my device.
The some result as the previous upgrade. The device has been rebooted after some second during the flash of the rom. At the device restart no OS or Data (locked on "Note 3" startup logo) but this is normal after a full wipe.
Furtunaly I restored my backup (made by recovery) and everything is back to normal situation before the wipe.
My question is... Some guy have found a similar problem with the new release of the recovery TWRP 3.0.2-0?
My device is a Samsung Galaxy Note 3 (Qualcom international)
I have had the same issue with some roms.
Touchwiz roms often fail to update and the recovery boots into recovery again.
No errors, just random reboot at initiating the installation.
CM13 and latest AOSP roms seem to flash without any issue.
Try going back to 2.8.7.X it will work.
Too bad you will loose the theme and glossiness of TWRP3

Also please backup your data on your computer if your partitions are f2fs while downgrading.
You cannot use twrp 3 for aroma zip.

Click to collapse
First of all copy the backup files to PC. Flash the stock rom on your phone. Now root and install TWRP latest 3.0.2.0 and then try to restore the backup again
Hope it helps
