long story short: just to assure myself for everything to go smoothly while installing Lineage OS 14.2 i stupidly decided to tick the 'system' box on factory reset for TWRP along with the standard data, cache and dalvik. now i tried to system restore the backup i have on my sd card and it says error 225 at the end and its stuck on boot!
what have i done wrong? can you no longer restore if you tickbox the 'system' thing; does the backup option not backup literally everything? did my files corrupt? will the 'format data' option (deleting everything on internal storage), then trying to restore fix it? HELP.
Do you wipe system before backup?
Maybe you should to flash your phone with odin

I have searched online, and there is no definative reliable content on what portions of memory I can delete safely without loosing the nandroid backup. What I mean is, I have TWRP on my handset. Aside from the factory reset option, what else can I wipe? I am asking because I built a Cyanogenmod unofficial image, and flashed my handset with it. The phone booted ok; I got an error about NFC service stopping. So I restored the phone back to a previous nandroid image. I then, tried to install my image again. This time the phone goes into download mode. I think I saw something online about how doing advanced clean would fix this. So when I log into TWRP I have the following options:
Davlic Cache, System, Data, Internal Storage, Cache, and Micro SDcard. How can I know where my nandroid backups reside so I can avoid clearing that portion?

By default nandroid backup is on internal storage but you can choose to save it on sd card as well. Tap on the top box/menu after you enter restore menu. If you choose sd card and twrp shows no backup then the backup is on internal storage. Explore a bit mate.
Or use file explorer check twrp folder in both storage. There should be subfolder of 'backup' in it.
You don't need factory reset. And just choose wipe cache/dalvik/system/data to install new rom/restore nandroid backup
I am trying to reinstall the original system and data onto my S5. I had Cyanogenmod on it, but before I installed CM12, I made a backup of {System, Boot, Data, Modem} as they existed with the stock system using TWRP.
I restored the partitions from my TWRP backup. Now when it boots, after the Samsung animation is shown, I am presented with a screen that says "Device memory damaged" (see attached image).
If I click the "Reset device" button, it boots into TWRP and attempts to clear some data. I assume it's not working because Samsung's stock recovery is supposed to do some magic that TWRP isn't capable of?
I have tried to clear the cache partition, and also tried to restore the data from backup more than once. The MD5 check on my backup files passes. Any ideas?
flash with correct pit and try to root, install cwm/twrp, restore your backup rom
I got it sorted out. I had to use Odin to flash the stock rom, which I downloaded from a questionable source online.
I just rooted my phone yesterday and I tried to delete a TWRP backup that was on my internal memory. I was unable to find out how to do it and set permissions in TWRP, which caused my phone to start booting with unable to start messages and a black screen. I tried restoring a backup and I wiped and restored, both have still same issue.
So at the moment I can start TWRP or factory reset, but as of yet, I cannot restore my backup.
When I backed up the phone I didn't select everything, I left out data.
Since you didn't backup your data, they are a few options. Wipe dalvik and cache from recovery, dirty flash a rom, clean flash a rom.

I was using an old version of twrp. I updated to 2.8.6.0 and it all works now, thanks.
Hello,
before I played around with getting root and flashing custom roms, I backup everything in Samsung Smart Switch.
After getting root and install TWRP, I backup the whole system (except the recovery partition) to the external sd-card from TWRP.
Now - after getting some experience with custom roms - I will go back to the stock rom from my TWRP-Backup. Set everything to factory default, wipe cache and dalvik and press restore. Select my backup... swipe to flash... everything seems ok. After reboot - no bootloop - a thousands of alert-messages pops up "blabla-app stopped"... Then appears only a black screen.
How can i restore my backup from TWRP? Or is there a stock-rom, so i can backup from smart switch? My System is a LRX21T.G900FXXU1BOJ1
Thanks alot!
Try clearing the caches from recovery and boot again
If it fails, try wiping everything again, then restore all partitions except DATA
See if it boots
If it boots - either reinstall apps etc manually, or use TiBu to restore the DATA partition
I've got it!
I flashed a stock rom with odin and restore with smart switch. Some settings are missing, but i think 90% is restored
Nice job
Hello,
I recently did a backup (NucleaROM, 7.1) in TWRP and it strangely went to 101%. Stuck on "generating md5" for a minute.
Then, when I restarted my phone, it acted like 2 times slower than usual, from the boot animation, and didn't stop.
I then did a factory reset and tried flashing the ROM and Gapps again. Open GApps project couldn't finish, TWRP rebooted.
I received the "swipe to allow modifications" slide and actually slided it the second time, because I wasn't able to restore the first time, when I clicked on read only.
I now am stuck in the recovery, I have backups on my external card, TWRP won't read Internal card, I can't factory reset due to mount error and therefore can't restore any backup.
Everything went wrong just after trying to do a normal backup. What did I miss ?
Thx
Well good thing you have a backup on your external card. I'll suggest you perform a "Format Data" in the Advanced Wipe section of TWRP. It should be able to solve it. Looks like a minor corrupted storage problem.
