[Q] How do I erase my ROM?

I've searched for hours all over Google and this website for something that is done in two seconds on my Evo 3D yet on this model phone I can't figure it out at all. Can someone show me how I can wipe the /system partition on this phone? I installed the latest CyanogenMod fine and installed the latest gapps only later to find out the CWM recovery doesn't automatically check file MD5s and installed a corrupted gapps. Now I've erased the /data and /cache partitions multiple times along with reflashed only the CyanogenMod fresh yet no matter what ever since that gapps install I keep getting random force closure messages 2+ times a second about the stock keyboard and I can't type anything.

Problems after Updates and Wipes

Hi,
my G3 and me have a small problem.
I wanted to update from official Cyanogenmod 12.1 to 13.0, backed up my data, etc.
First, there were tno Problems, but very fast battery drainage, and that my mSD card was now not "sdcard1" anymore but some numbers.
I tried fixing permissions in TWRP, had a bootloop. Updated TWRP (now 3.0.0 installed) and it worked somehow.
After one night it said process.acore quit unexpectedly. I had some crashes of the Google Play Services as well.
Then, it would boot, give me like 10 Seconds, and then jump to the boot screen of Cyanogenmod.
I tried to wipe data,system,dalvik. First there were problems with wiping dalvik, then there were problems with wiping system.
It says can't mount system: invalid argument. When looking around with twrp file explorer, the system folder is empty.
I would really appreciate your help!

You must check the partition type. Check if this as Ext4 or f2fs. In any case, try to repair the system of partitions from TWRP.

Okay, so:
Filesystem of /system is ext4
When trying to fix:
Repairing System using ef2fsck....
/sbin/e2fsck -fp /dev/block/mmcblk0p40 process ended with ERROR: 8
Unable to repair file system.
I assume it's because its ext4 and not f2fs?
btw I found something that may be important: when I try to wipe /cache, it takes forever.

Try to reinstall cyanogedmon 12.1 without wipes. Then, you enter again to the recovery and apply the wipes. I am not sure if for our model, cyanogedmon is compatible with the type of partitions f2fs and if is required a kernel with support for f2fs file system. You could try to changing the partitions (file system to f2fs), installing the rom and see if it starts but could cause a boot loop. Make a nandroid before making any changes.

Okay,
when trying to install the latest Snapshot of official CM, it just says ZIP File is corrupt. It said the same about an older build I still had on my PC.
When I try to flash the CM 13.0 build i had previously, TWRP just goes black and reboots (into recovery).
I also have to manually mount /system every time. If I try to mount /system again after dismounting it, it says 'failed to mount /system : Invalid Argument' .
This applies to all other partitions but the external SD Card.
When I try to change the file system to f2fs, it says OPeration successfull, but it didn't change anything, and the file system keeps being displayed as ext4.
Furthermore, i can't just 'Reboot Recovery' with TWRP- I have to take ot the Battery every time.

Which is your recovery version? If your recovery version is 3.0, you could try performing a downgrade of your recovery. If the errors persist, make an clean installation of the rom from LG Flash Tool (KDZ).

My Version is indeed 3.0. I had 2.8 before. Should I downgrade even further?
What would you recommend?
Besides:
I tried saving my files with the Terminal and [cp * /data/data/media/ /external_sd/Backup -r] and others, but it keeps giving me Zero-Byte Files.
Is this due to the Recovery version too?
You guys really are a big help! Thanks!

I think that you try to save an empty folder. Use any backup applications to accomplish this. I have installed recovery twrp version 3 and I have no problem.

Ok but doing it woth cp * /sdcard/WhatsApp it keeps doing the same.
The only thing that matters to me now are my WhatsApp Images
I was able to grab the chatlogs but not more.
Sometimes it even copies all pictures (Like 8.000 files) but all of them are 0-Bytes.
I will try the downgrade tomorrow.
Thank you so far!

Were you able to resolve this? I have an identical issue. I was playing CoC on my LS990 with CM13 before it went black and now it always boots in to twrp recovery 3.0. The only thing that mounts is the external sd card.
I've tried the following and all fail:
adb push cm13 and then install from recovery
adb sideload cm13
lg flash tool via firmware upgrade, roms:ZV4, ZV6, ZV8
Is the internal sd damaged? Please help XDA gods. Thanks

[FLASHABLE_SCRIPT][UPDATED_ERRORS FIXED] Increase system space to 1.2/2GB [15/7/2017]

-By following this you can can increase /system space from default 800MB to 1.2GB/2GB
-You can flash gapps on CM ROMs without insufficient space issue.
-You can flash regular MIUI ROMs too,without any issue.
Statutory warning
*Repartition can kill your phone forever if anything goes wrong,so proceed with caution (and make sure you have at least 30% battery)
*This process would format your internal sdcard,backup its contents
*I'm not responsible If your phone dies during this procedure under any circumstances beyond control
Prerequisites:
1)Redmi 1s partition script_system space 1.2GB.zip/2GB.zip
2)Parted
3)Twrp v3.0.2-1.zip
4)Download and copy all these files to external sdcard
Procedure:
1)Flash Twrp recovery(incase if aren't already using it).
2)Boot in to Twrp--->Advanced--->File manager--->Browse to the location of file "parted"--->Select "parted"--->Copy File--->/sbin.
3)Now using Twrp File manager browse /sbin--->parted--->select parted--->chmod 755.
4)You can also use "aroma file manager" instead of Twrp file manager for copying "parted" to "/sbin" and changing it's permissions to 755.
5)In Twrp flash "Redmi 1s partition script_system space 1.2GB.zip/2GB.zip" and wait for the script to finish execution(recovery will reboot automatically once this process finishes).
6)In Twrp--->Wipe--->Advanced wipe--->Mark in "Dalvik/ART Cache"__"Cache"__"System"__"Data"__"Internal Storage"--->Swipe to wipe.
7)Reboot recovery.
8)Install your ROM(don't flash gapps now).
9)Back again to Twrp start screen select "Wipe"-->Advanced wipe-->select/mark "System"-->press "Repair or change file system(notice that size hasn't increased to 1.2GB/2GB)-->Resize file system.
10)Back(though size of partition appears unchanged, its actually increased to 1.2GB)-->Back>select/mark"System"-->Repair or change file system-->Notice size of partition increased.
10)Back to Twrp start screen and flash gapps,that's it.
Reset to default partition:
1)I am also giving link for flashabe script file "Reset to default partition.zip" for restoring default partition sizes.
2)Boot in to Twrp--->Advanced--->File manager--->Browse to the location of file "parted"--->Select "parted"--->Copy File--->/sbin.
3)Now using Twrp File manager browse /sbin--->parted--->select parted--->chmod 755.
4)You can also use "aroma file manager" instead of Twrp file manage for copying "parted" to "/sbin" and changing it's permissions to 755.
5)In Twrp flash "Reset to default partition.zip" and wait for the script to finish execution(recovery will reboot automatically once this process finishes).
6)In Twrp--->Wipe--->Advanced wipe--->Mark in "Dalvik/ART Cache"__"Cache"__"System"__"Data"__"Internal Storage"--->Swipe to wipe.
7)Reboot recovery.
8)that's it you are back to default partition.
PS:
1.Need for "Resizing System partition"(step 9) comes only with CM14.1(haven't tried other CM versions or other custom roms) no need to do that if you are flasing MIUI ROMs(i,e you can skip step 9 if you are flashing MIUI ROMs)
2.If you still need more System space or want to further modify partition table(only if you know what you are doing),you can edit "update-binary" file inside the zip as per your needs.

good work mate

Great tutorial! Have a some questions:
1. After successfully doing this, If I decided to full clean wipe system, data, cache, dalvik cache, internal storage, and format data, the size will be reset? Do I need to do all the steps again?
2. If I decided to go back in default partition size I just flash that to reset all the steps? Or there will be a steps to reset all I've done?
Thank you.

1.You can do all the wiping as usual, size of partition wil stay as it is and won't get reset,but if you're flashing current version of cm14.1 again you need to resize "System" partition before flashing gapps.
2.You additionally need to change "System" partition too to F2FS and than to EXT4(like you do with "Data" partition),in case you're going back to default partition.
I forgot to mention point 2 in OP,I will now add this there

Based upon the scenario, the only concern is the system partition coz newer or update partition is too large. Cache partition is ok because it only use as a temp file partition. The userdata partition is large as internal storage because it shared as the same partition. That is the good thing at xiaomi phones, data partition is large as long as you have space in internal storage.

Guys please help me:
Today morning I reparationed my Redmi 1s as the Op said. it went successful. after using for 5hours I've found an update from CM. So I updated using CM UPDATER APP. after reboot I've lost my Google play store and Google app (after updating to todays CM update using CM UPDATER APP). When I went to see the system partition size, it's size went back to the default 782mb (around 782mb, I don't remember exact size).
I checked whether it is disabled or what in apps. But I can't find there also. I tried Show system apps and reset app preferences, but nothing showed them.
I tried to get them back (play store and Google app) by resizing the partition to 1.2 gb (wipe>advanced wipe> Mark system>change or resize partition>back> checked system partition size whether 1.2gb or not>wipe cache and dalvik cache> reboot to system). But nothing worked.
So please help me in getting them back. Please exclude solution such as factory reset or flash gaggs again.
Is anybody else also facing the same issue or it's just me?:crying::crying::crying:

3)Saw your posts on cm41.1 thread too,so you're on latest twrp
but still facing error 7,If possible post a screenshot of error 7(coz it never happed for me)
4)coming to the issue at hand,could you able to mount cache,system and data partitions.In twrp go to wipe>>advanced wipe>>select "cache">>Repair/change filesystem and see if everything(regarding partition size)is ok there.
Then do same for system and data too and check how are those partitions,if possible post screenshots.

Updating from CyanogenMod

Hi,
currently I am running CyanogenMod 13 on my Samsung Galaxy S4 Mini (serranoltexx). Now, as it get's outdated and insecure, I am about to update it to LineageOS. But I am worried, because I can't just flash the ROM over CM, but I have to wipe everything. Sure, I can take backups of all my data, but my question is:
What do I have to select in Clockworkmod Recovery in order to clean up for LineageOS? And the second point is that I parted my SD-Card to use Android's option to emulate one partition as internal storage. So if I wipe, can I keep the partitions and what do I have to save before?
Oh and.. I have tried to do a Nandroid Backup, but I can't copy it onto my PC because the storage is mounted differently within CyanogenMod (the 2 partitions I wrote about) and ADB doesn't work for this either.
I hope somebody can help me

Done! /ReqClose
Hi,
I'm glad to say that I have done it yesterday. The thread can be closed and for all who have the same questions I had:
First of all I took a backup of all my data (Apps, Music, Photos etc) and put LineageOS, GApps & SuperSU on my SD-Card. Then I booted into my recovery (CWM) and wiped all data. Unfortunately it didn't work (CWM said something like "error in lineageos.zip") so I decided to use TWRP for it. There was just an unofficial build but I didn't care too much, so I used this one. It was an img file, so I needed to convert it to .tar.md5 first using a tool I found in the Internet. So I flashed TWRP then using Odin. When I booted into TWRP everything seemed to work, but when I tried to install the zip file it just rebooted immediately without an installation. So I finally used ADB sideload, and it finally worked! Now my phone is working fine!
Hope this helps someone!!

TWRP Weird folder names and no .zip file

Hey,
I'm new in this kind of stuff but need help as fast as possible. So I tried to root the phone but let me tell you something else. When I enter TWRT (boot into) and try to install the .zip file it shows weird folder names that I can't see on the computer. I have Win10 if this matters and Android 8.0 or 8.0.1. The folders are:
acct
boot
cache
config
cust
data
license
mnt
and it goes like that. The problem is that about 85 or 90% of these folders aren't visible on my computer when I plug in my phone... The System is mounted in TWRP and everything is mounted. I tried wiping all the data. I have unlocked bootloader. Also when I go to some of these folders I see REALLY strange folder names like: 671hnsuh1b%nqjus Or something like. I've found out that it's encrypted but I just want to root the phone and find the .zip file. Also can someone explain me these acct, boot, license, vendor, version and other folders that aren't visible on my PC? Please help. I'm so confused, not clue what's going on...

You need to use the format data option to decrypt the internal storage. Better use SD card or USB OTG to flash the root file. Anyway don't wipe the oeminfo or vendor partition in any case and take a backup of all partition beforehand.

Well, I already used this option. The format data option and it's still the same. Maybe the version of my twrp helps: 3.1.1-1

Strange. What is the android version?Did you had any lock screen set before formatting? Can you please share a screenshot or log during formatting, if you have any. Anyway you can use adb sideload to flash the .zip file.Cheers

My android version is 8.0 so it's oreo. I've also noticed that the 3.1.1-1 version of twrp is the only one from what I tried that I can install the newer versions gave me an error. I had lock screen and it was code not a fingerprint but I wasn't prompt for a code after booting into twrp. Adb sideload seems to fail all the time so I can't do it :/.
The logs from wiping data are:
Updating partition details...
..done
Full SELinux support is present.
MTP Enabled
Starting ADB Sideload feature...
Starting ADB Sideload feature... (And it failed now wipe logs.):
Fomatting Data using mkfs.f2fs...
Done.
You may need to reboot recovery to be able to use /data again.
Updating partition details...
...done
So yea I'm so sad tbh with this... I'll try to install new twrp after the wipe if the wipe didn't help and will tell you if I get an error when I try to boot into NEW twrp.
EDIT: Ye still an error.
Maybe you have a link to the newest working twrp?

Nevermind got it. Downloaded the modded twrp by TEAM MT I guess from here: https://forum.xda-developers.com/honor-8-pro/development/wip-twrp-3-1-1-0-duk-t3625798 Works perfectly and SOLVED!
