TWRP can't mount /system

I tried dual boot my redmi note 4g using an chinese software. As I don't know chinese Ijust followed instructions given on source site. I got dual boot on my phone successfully. But after incomplete installation of second rom i wiped cache which cause my phone an bootloop formatting my internal memory.
I tried installing official miui rom through recovery. But TWRP gave me error of unable to mount /system.
After some research I found that
Code:
/dev/block/platform/sdcc.1/by-name/system2
is causing problem.
This file mounts at /system partition. The actual name should be
Code:
/dev/block/platform/sdcc.1/by-name/system
.
I want to rename this file. I tried many ways but it gets renamed back after each reboot. This is also preventing from installing rom through fastboot method. I guess I will have to do changes somewhere else through partition table. I don't know much about this so what exactly I should do to rename
Code:
/dev/block/platform/sdcc.1/by-name/system2
to
Code:
/dev/block/platform/sdcc.1/by-name/system
.
Sorry for bad english.

[ Backup with ADB through Recovery TWRP 3.0.2-r5 or TWRP 3.1.0-0 ]

[ Backup with ADB through Recovery TWRP 3.0.2-r5 or TWRP 3.1.0-0 ]​
I found out how to backup easy through Recovery with ADB and create this software to help you get easy with that, just execute it and follow what is write in there!
​
Download the zip, extract the folder, boot in twrp and plug the usb cable, open the folder and execute the exe file, select the option and follow what is write. The backup files will be stored in Rom_Backup folder!
To restore the partitions you need to do a backup first from the same partitions then do a restore!

Hello.
Forgive my silly question, but I want to be sure I don't create a mess.
In May I was with stock rom rooted with 8+8 GB and I've done a backup with your tool, so now on my pc I have the file Backup_14052017.bak.
Then I've flashed LineageOS 13.0 for Alcatel ONETOUCH IDOL 3 4.7 rom by alecbl.
Now I want to go back to that stock rom.
Can I do it just restoring that backup, right? And then I'll have back the stock rom 8+8, and all the data I had in may, correct?
Thanks.
Luigi.

Stick with Lineage - personna bricked his phone .........

OOps, doesn't suond funny...
Bricked using the restore option???

So, I'm trying to restoring that backup.
I've rebooted the phone in TWRP, plugged it to pc, launched ROM_BACKUP.exe, choosen 1 - Restore Backup and written backup's name.
But I get the error "adb: unable to connect for restore" (see attachment).
I have debug usb enabled and USB Computer Connection set on Camera(PTP).
What am I missing?
Thanks.
Luigi.

The latest TWRP from FireLord. You need to be on the recovery for restore to work.

Which version is the latest? I have 3.1.0-0.
I've turned off the phone, then pushed power+volume up for booting on TWRP.
I'm in the initial screen, the one with 'Install', 'Wipe', 'Backup', 'Restore', 'Mount', 'Settings', 'Advanced', 'Reboot' when trying to restore.
Mabe is something wrong on my pc with adb.
In my ROM_BACKUP folder I have (don't remember if they were originally there or if I've moved something in that folder)
adb.exe
AdbWinApi.dll
AdbWinApi_build.dll
AdbWinUsbApi.dll
Backup_14052017.bak
ROM_BACKUP.exe
I've tried opening command line from that folder and writing 'adb devices' for seeing if everything was ok.
I've got the message 'List of devices attached' but nothing about the device.
So it seems there's something missing...
Thanks as usual!

Found it, but in the download page it says
twrp-3.1.1-idol3.img

Will it work also on Alcatel Idol 3 4.7?

Ehhhh... I don't know. I would suggest hitting someone up to build the latest TWRP for the 4.7 Idol 3.

solquest - I would suggest you use personna's TWRP he made - that is the one he used to check this works on his phone
check his posts

Do you mean TWRP 3.0.2-r5 and TWRP 3.1.0-0?
Tried them both but always got this message:
command id: 'adbrestore' and there is no value
E:Unable to find file system (first period).
E:Unable to find file system (first period).
E:Unknown restore method for '/system'
E:ADB Restore failed.
Done processing script file.
Checking online, mine doesn't seem the only case: https://github.com/omnirom/android_bootable_recovery/issues/133

Well the latest TWRP is by alecbl on the lineage thread towards the end - 3.1.1.0 - try that one and see if that works....

Found and tried.
Restoring finally worked and it said it restored system and also data (while I thought with ROM_BACKUP I would have restored only system).
The problem now is that phone doesn't boot... I get the ALCATEL ONETOUCHE powered by ANDROID screen, then the Idol 3 screen, then the blue android forming and then it reboot.
Any idea on what to do?

Wipe Data. Sometimes it kills phones.

I've wiped Data, Cache and Dalvik, but nothing changes.
Sometimes I just get the first screen (ALCATEL onetouch - powered by Android) and then it reboots, sometimes it goes a bit further with the other two screens (Idol 3 and the droid getting blue) but then it reboots again.
Should I try with Repair or Change File System?
On TWRP I've tried to restore data (but don't know if that would have helped) but when I select the Package to restore (2017-05-14-07-37-44_LRX22G_release_keys) I get the error 'No partition selected for restore'.

Any chance to get back to 5.0.2 stock rom without restoring that backup?
In case, could I install again LineageOS 13.0 for Alcatel ONETOUCH IDOL 3 4.7 rom by alecbl?
Thanks.

On TWRP when I try to restore data (hoping that this would make phone booting ok) I am asked 'Select Partition to Restore:' but there's nothing I can select... and if I swipe to resore I get the error 'No partition selected for restore'.
Can't I restore the backup I've done with TWRP?
---------- Post added at 13:30 ---------- Previous post was at 12:42 ----------
trying to flash LineageOS 13.0 for Alcatel ONETOUCH IDOL 3 4.7 rom by alecbl again I get these messages:

Then tried restore via adb and got the message:

Then wiped again data and cache and flashed again LineageOS 13.0 for Alcatel ONETOUCH IDOL 3 4.7 rom by alecbl (with august security patch).
But still the phone keeps rebooting after the first screen.

Phone not accessable after trying to install Custom Rom

Hi,
so i've tried to root my phone and then to install a custom rom. the root went without any problem. After the root, i tried to install lineage OS 16.0 and followed this guide:
https://forum.xda-developers.com/redmi-note-7/development/rom-lineageos-16-0-t3923203
i downloaded the rom and gapps, put them on my root directory of my phone and then i wiped System,Cache ,Data, Internal Storage and Format Data. After wiping, the roms were gone, so i rebooted and transfered them again into the root directory. Then, i went onto installing (just like i did with magisk) but an error occurred saying:
E: String resource 'zip_compatible_err' not found. Using default value.
Zip Treble compatibility error!
Invalid zip file format!
Error installing zip file '....'
Updating partition details...
...done
Ok. So then, i tried to install another Custom Rom so i went for Oxygen OS, it actually did install but then i couldn't boot into it because it was telling me there was an 'Android System Error'. Ok, back in TWRP, i wiped everything and then i tried to install the Original ROM but i got the same error as above.
For now i tried to download the miFlasher tool but it only wants to download some driver and it literally takes forever.
Hope you can help me...

Download Fastboot ROM for your device and do this Fastboot Method

Those recoveries are old.. Use orange fox recovery 10.0-2 it will work and format data then install rom.

title?
@BlackGarnett
Thanks, that help me on a quick one!
@loseyourself
Also thank you for this advice, i'm new to rooting smartphones and install cfw since i was using iPhone for the past few years.
But now i got another new question: if i use orange fox recovery and i run a backup with it (i think there will be an option to do a backup), then i format all data and internal storage, can i still recover from the backup or will it be deleted?
thanks again!

[SOLVED] Not able to flash Any ROM via TWRP

I have the MIUI v12.0.3, that's is full working, installed by Fastboot and XiaomiFlash. Then I flash the recovery TWRP mauronofrio and if I try to install any ROM what I get is a reboot into the recovery....
If I browse with the recovery into my files they are gone, in the root there are just a lot of folders with strange names like "7fdhuyfdsgu8fdhdH8fdhHBJN", inside those folder other strange folders.
The strange behaviour is that if I try to upload anything with a PC while the recovery in mounting a partition the file just won't upload, it sticks on 0%.
The only way to have a functioning OS is then use the XiaomiFlash again a flash the original latest MIUI.
This is SO WEIRD . I don't know how to do.
By now I have tried this ROMs:
- Havoc OS
- Resurrection Remix
Do you have any helps? I think is something with encryption, because when I try to save the log on the SD card with TWRP I get
E:Unable to decrypt FBE device
UPDATE:
I found this topic: https://forum.xda-developers.com/showpost.php?p=80209338&postcount=2
Following what the comment says, I figured out to Boot the ROM Havoc-OS... BUT all my data are still crypted I guess...
I installed a simple file manager from the play store and what I see are all the strange folders in the root of the phone...
SOLUTION:
After following that thread, what I had to do is just use TWRP mauronofrio and Format Data (not wipe). This will erase everything and solve the crypto problem. :good:

Before installing rom in twrp, the system entry is never deleted, the Dalvik / Art Cache cache, Data, Cache is cleared, rom is installed and Data is formatted.

I am not understanding... just wiped Dalvik/ART Cache, Data, Cache withoud problems, but System still can not be wiped... I format Data too without problem... what I should do now?

You must first install firmware 11, preferably the latest version, for example POCO M3 EEA Stable Recovery V12.5.5.0.RJFEUXM. Move it to sdkard, go to TWRP and delete: 1.Dalvik / ART Cache 2. Data 3. Internal storage 4.Cache DO NOT DELETE OTHER! 5. Start the A11 firmware installation 6. FORMATTING after installation. 7. Restart I recommend installing the firmware for a better system installation.

Remember, don't delete anything extra.

Ok, I tested a while and it seems that call recording does not work... this is why I would like to try some custom roms. My target is to have a working call recording without "audible announcing of record start". What should I do now to successfully install, for example, cdDroid?

Custom rom installation is done in the same way as firmware,
Clean Dalvik / Art Cache, Data Cache, Install Rom and Format Data.

ok, crDroid installed but it goes in boot loop... i think because juice version is not proper for citrus...
I will try other roms.... thank you very very much rotoko!!
