[Q] I can't restore my cwm backup, what should I do? [urgent,please help]

Hi,
I had a problem with my NDT miui nand buil recently, it was sticking on boot animation, so I made a backup via cwm, I saved the backup folder on my pc. Now I want to restore that backup. I tried all the usual methods for it, I did tas29, flashed new clk, and tried backup, still stuck on boot animation, I flashed my last rom and then tried to restore the backup, again stuck on boot animation. I did everything for it, but doesn't works for me. It does the restore process as usual, but I wan't to boot, my phone stuck in boot animation. So I beg you to help me with one of these alternatives, please.
-I only want to restore my contacts, call logs and sms. Anyway to restore them only? there are some .img files in backup folder, which one are these files stored?
-Is there anyway I can extract backups files on my pc and get my contacts,sms,... in it?
-If none of above works, is there anyway to install cwm on pc android emulator, and then restore my backup in it, and again get my contacts,sms there?
I will really be thankful of your helps

Are you using the correct partition size? Too small a partition normally causes the phone to hang at the bootanimation. If you have used the correct partition size and it still doesn't boot, try simply increasing it to account for any bad blocks you may have.
It's also possible that your backup is corrupted somehow, it happened to me once. If this is the case, try flashing the same ROM and then restoring the data partition in CWM.

When you rename backup file do not use spaces (exp. icsromv3)

I don't think that's the problem because if the ROM gets up to the bootanimation (after a Task29) then it's clearly been [somewhat] flashed correctly so it's probably down to the backup itself, or of course an error somewhere on his part.

Come on guys, this is common sense. If he made the backup with the rom ALREADY not booting up, no matter what he does, it'll always stick to the boot animation.
The back-up saves your ROM at its current state, not the one it was working at before. Backups should only be done when your ROM is actually fully functioning, not when it is broken. So unfortunately, you have to do what Nigel Suggested. Make a clean install of that ROM and then only restore the data partition.
You may be able to do the emulator thingy, but I'm not sure, you can give it a shot though.

For extracting something from your backup see appextractor or nandroid browser

Whoops, I should have read the OP more carefully
@OP Yeah, just fresh install then restore the data partition. I still don't understand why the other ROM isn't working though unless it's your fault somwhere

S7 edge With s8 port

Hello.
I am sorry for dumb question.
But i dont understand very well
I am on sac23 rom s8 port
My question is that when if I wanted to flash a mod Like air command etc.
Will i have to download it of s8 or s7 edge
I mean like i had selected my device as s7edge in xda app
Should i stay on that or because of the port i should change it to s8 for mods ?
Sorry if i didnt explained well.
Thanks in advance

Stick to S7
Also do not forget to make a backup in TWRP might save you a lot of hassle if one flash goes wrong
:good:

it is not reccomended to do this (its called a dirty flash) you can choose to do this anyway when installing a custom ROM most of them come with an option in the AROMA installer letting you do a fresh wipe or "dirty flash" it will just install the ROM over your current leaving your settings/apps there. Or if there is no AROMA installer with the rom just dont do a wipe before you install. no need to restore using a backup
dirty flash should be fine if you are upgrading ROMS to a later version but you should always check the thread if that is okay. you may run into problems if its a huge update.

heres some info on EFS > http://www.naldotech.com/galaxy-s7-s7-edge-backup-restore-efs-imei-partition/
recovery is TWRP itself
system is the ROM
Data is your apps etc..
a standard backup is already seleted in TWRP which is
Boot / System / Data
you may as well backup EFS as well its only a few Kb

A bundle of thanks mate. Thumbs up

can't extract apps from nandroid made otg with twrp

My phone was stuck in a bootloop where it could only get to recovery. Using the recovery I created a nandroid backup to the a USB stick using an OTG cable. I flashed the stock firmware and got things setup but I can't restore individuals apps from the nandroid. I copied the nandroid from the usb to sd card but it still doesn't work. I tried restoring apps using Nandroid Manager but when the app is launched it gives the error "app has stopped, close app". For some reasons sms succesfully restored but no user apps. I tried restoring with AppExtractor but it gives the error "unable to generate apk listing"
I also have titanium backup pro but couldn't get it to find the location of the nandroid to try extracting with it.
Any ideas? I really just want my messages back from Whatsapp.
My phone had stock Nougat with busybox installed and elementalx kernel. It should be the same environment now as when the backups were made.

@twoplustwo can you tell us why your phone went into bootloop ? If you know then you can restore /data from TWRP and revert the cause of bootloop..
Also can you confirm it's in capital letters as you have mentioned in small letters in another thread that twrp/backups rename them to TWRP/BACKUPS or move them to internal storage.. (in stock ROM if i am not wrong, TWRP folder is not accessible, so try to install custom ROM for temporary purpose, then move backup to internal and then try with titanium backup..)

yes it was in capital letters
the problem in the first place that sent the phone into a bootloop was I installed the OTA security update. I'm running stock rom but I guess because it was rooted and had busybox, that made it incompatible with the update?

If you have TWRP and take update, it don't cause bootloop, but it cause your device to boot into recovery when you turn on your device.. can you confirm if it was bootloop or problem of booting to TWRP ?

I am unable to copy the nandroid to internal storage. I tried using usb to computer and it just does nothing. I tried root explorer and it says 'copy failed' and file manager says 'cannot load'. This only happens with the TWRP folder inside the internal memory specifically.

I can confirm it was only booting TWRP. So even when I tried to boot to system it just booted to TWRP again.

You don't need to worry,
Do you have any important data for any app currently ?
Take backup of new important data with titanium.. (and then again take backup from TWRP, for safety )
And then simply restore /data from TWRP backup, it will give you older data back without any bootloop but you will loose new data/messages that you got after flashing/ on current running ROM..

Thank you sir! To confirm, when backing up to USB stick with OTG, does the format of the USB matter? Is fat32 safe?

Not familiar with different formats, it should work.. bu t
You can backup to internal storage too, since you don't have to flash fastboot ROM again..

file corruption.

hi, i have a sm-t510 with android 9, and im trying to install twrp but everytime i try i get some kind of wierd file corruption. all my files in sdcar are named with random numbers and letters and there is nothing in it. the tablet boot normaly, but i cant install anything or acces any of my normal file. is there anyway to fix that, or does anyone has a data back up i can use for that version XAC-T510XXU2ASK5. thank you.

Didn't read the instructions very carefully, now did you? The very FIRST thing you need to do when booting to TWRP is to FORMAT THE DATA PARTITION. Not wipe, but FORMAT. The data partition is encrypted and TWRP can't read it. That is why everything looks weird. Also, that is why you need to backup any pictures, downloads or anyting else you want to save because formating the partition will erase EVERYTHING and not just system stuff that wiping deletes.

I have been rooting phones and tablet for the past 10 years its the first time it happens. Maybe its something new. Thanks for the info. But i already format the data and evwrything disapeared beside a file named twrp. And i cant reatore the data, cause i didnt have twrp to back them up. So if you have another sugestion, i am all ear

My post pointed out that formatting would erase everything and that you should backup prior to doing it. And there are several other methods of backing up data and apps besides TWRP. Yes, it leaves the data partition blank, but flashing a ROM and gapps will put the directories back. Of course, they will still be empty. If you used a Google Account, then that should have at least backed up your apps and some settings. When you setup a new ROM, it should let you restore them.
BTW, yes it was the first time it happened for most of us. Samsung keeps trying to improve "security" and adding encryption, by default, to the data partition is in all of their new tablets and phones.

You can't backup a stock ROM with TWRP because it can't handle the encryption. But you can use TWRP to root a stock ROM. In that case you just ignore the wierd internal data and put what you want to flash only on the external SD. IOW, if your reason for flashing TWRP is to use its backup function on a stock, don't bother, it won't work. But if your intent is to ROOT the stock ROM, then go ahead, but DON'T format data. Just put the files needed to root on the external SD and flash from there. You format the data partition in order to flash a custom ROM.

help about /vendor

im having big problems about vendor. for start im giving some info:
device: mi a1 (tissot)
current os: lineage OS 17.1
root: yes
twrp: can install or use just booting .img
i unlocked my device and installed twrp. there is no problem.
i wanted flash lineage OS and i wiped my device. gives error about cannot mount /vendor
i installed treble supported twrp and installed lineage OS. flashed magisk. installed microg...
then i tried flash mapsv1.zip which is recommended for microg. then booom. another /vendor error.
now i can boot device. i can use everything except gps. google maps app cannot found location. yandex maps can found and i can use it until lock screen or going main screen (or another app). then it starts stopping everytime until i clen its data and cache. then again... in chrome when i open google maps and try found my location chrome stops.
i tried to change /vendor/etc/gps.conf. its still same.
what to do now guys? im worrying about if i try re-flash rom it doesnt flash and device bricked. any solution without re-flash rom? what causes to cannot mount /vendor after solved it?

What exactly did you wipe? I think you wiped vendor, or bumped your O.S. from an old firmware. However, wiping system, data and Dalvik was more than enough.
To solve this, the worst thing to do is trying to hook around. Just reflash the latest original firmware and start again.
Keep in mind that you might need to backup your stuff first.
Use adb pull and push commands in case your device is rebooting too much. Check if device works well this time.
Next, open adb access from device and reboot fastboot to reflash your custom recovery, then reboot recovery and wipe just these items. Finally, complete Rom flashing procedure, depending of your needs.

Dalvik cache , system, data, and cache. My device is not rebooting too much. Sory if i couldn't explain. Everything working fine except when an app tries use my location, app stops running, i cant flash anything right now.
İ thought anyone knows mapsv1.zip file(microg.org) and which files are replaced or added by this file when flash it. And can i do it manually? Btw i can read and write /vendor file with solid explorer
İf needed to re-flash rom thats ok but i think lineage OS was perfect for me until this error. And a last thing: can i backup my settings. (İ already took backup of everything in stock when unlocked bl)
Thank you for help
Edit: gps problems started when i tried flash mapsv1

ROM could be perfect, but what I doubt is how perfectly you followed the procedure. Again, better start from zero, being sure you have all the prerequisites (latest firmware included). My humble opinion.

Okey ilk try it and share the result night. But is it possible to backup settings of phone?

Well, that's why in step 0 is always recommended to backup you phone. At this level you should have nothing in settings, since you wipe it all... However, that's better, that's the goal of a Clean Install after all. Each ROM has its own flavour and is not recomendable to overwrite these values from a backup, if you're changing ROMs. What you could do, was to backup your apps and some settings with a third app like Swift Backup, or older Titanium Backup, before starting it all, or else, making a complete backup from recovery, in case you end with a problem with newly installed ROM (recommendation here is disable any screen security lock before doing Backups).

İ did it all. Step by step. But i realized something. That errors doesnt matter on my device. Bcs when i flashing stock mi flash tool said failed but i booted system and everything working fine. İ installed persistent twrp. Same error. Then wiped. Same error but wipe completed. Than i flashed this zips single and booted everytime: lineage os, magisk, backup of migrate. Everytime it said cannot mount vendor but all of this apps and os and recovery working fine

Are you sure? Bcs i can view and change /vendor in root path. Treblizing is updating and repairing system partitions right? İ am using treble support twrp, flashed stock rom via mi flash(said error but worked fine) then how to treblize a device? And is this required for anything(like a rom, an app)?
