As we now have functional recovery options on our tablets, and people will inevitably mess things up with their device, we need to get a way to get your tablets back to factory condition. But I need your help with this!
What do you want?
Here's my idea: We have all seen various ZIPs floating around, most of them leaked from somewhere. The problem with these is that you can't use OTA updates, and I'm not sure what Acer Service Center thinks of custom ROM installs. What I want is to build a list of software that is officially distributed by Acer, is OTA-updateable, etc. For this reason, I want people that have not yet modified their tablets (except root) to provide image dumps of their /system, /boot, /flexrom, and /recovery partition. It's really easy to do, and you'll help yourself and others when they get into trouble.
Can I help?
Answer all of the following questions. If at one point the answer is "Sorry, you can't help", well... You can't help
Is your device unlocked and rooted? Yes - You can help! / No - You can still help, but you need to unlock and root your device.
Do you have the original Acer ROM installed on your device? Yes - You can help! / No - Sorry, you can't help
Have you received the latest OTA updates for your device? Yes - You can help! / No - You can help as well!
Have you removed any apps or files from the /system or /flexrom partition? Yes - Sorry, you can't help / No - You can help!
Have you installed a custom recovery image? Yes - You can still help, as long as everything else is still original / No - You can help!
Okay, so I can help, now what?
If you can and are willing to help (remember, it could save your own ass one day), follow the instructions below. If you get stuck or simply don't know where to start but are willing to help, let us know in this thread and I'm sure we can all help eachother out.
This will not gather any personal data from you. Personal data is stored on the /data partition, which we don't need, so: No worries!
Root your device, if you haven't already.
Connect your tablet to your computer via ADB
Type the following command: adb shell. You are now logged into your tablet. You can exit at any time by typing exit and hitting ENTER.
Type the following command: dd if=/dev/block/mmcblk0p2 of=/sdcard/boot.img. This will copy your /boot partition to a file called boot.img on your internal storage. This one will be fast, it only has about 8MB to copy.
This step can be skipped if you have a custom recovery! Type the following command: dd if=/dev/block/mmcblk0p1 of=/sdcard/recovery.img. This will copy your /recovery partition to a file called recovery.img on your internal storage. This one will be fast as well, it only has about 6MB to copy.
Type the following command: dd if=/dev/block/mmcblk0p3 of=/sdcard/system.img. This will copy your /system partition to a file called system.img on your internal storage. This one will take a bit longer, it has about 360MB to copy.
Type the following command: dd if=/dev/block/mmcblk0p6 of=/sdcard/flexrom.img. This will copy your /flexrom partition to a file called flexrom.img on your internal storage. This one will take a bit longer as well, it has about 360MB to copy.
Type exit to exit the ADB shell. Copy the four .img files from your tablet (internal storage) to your computer. You might have to reboot your tablet if the files don't show up.
ZIP or RAR these files, and upload them somewhere. If you can't find a place to store them: send me a private message or reply in this thread and we'll arrange something else. If you have uploaded the files somewhere: again, send me a private message or reply in this thread.
So now what?
When I receive your files, I will package them into an update.zip that can be flashed from custom recoveries. This will then restore everything (including the custom recovery) to factory state, which can help you in getting your device back to stock.
What versions do you have already?
Acer_AV041_A510_1.044.00_WW_GEN1 (download links will follow shortly)
Acer_AV041_A510_1.098.00_EMEA_CUS1 (download links will follow shortly)

The idea sounds great so far. But I have a small problem to make a complete backup for my a511.
Your linked root tutorial for the procedure is only for a100/a510 and doesn't work for a511, as I understand.
The tutorial for rooting the a511 needs first to flash a CWM.
http://forum.xda-developers.com/showthread.php?t=1729432
So it isn't possible for us to backup the recovery partition, right ?
I have the stock Acer_AV041_511_1.028.00_EMEA_DE on my device.
Is it even possible to backup and recover the baseband ?
I'm very interested in your CWM recovery for a511 too, but since many guys f++++d up their device now, I want to make sure that my device will not goes the same way.
i can help, n my tab is rooted.
but i don understand the first step: Connect your tablet to your computer via ADB
What about if we have removed system apps (such as the antivirus that comes with the tablet). It wouldn't be a complete dump if it didn't include those.
I have root and am happy to provide a dump, but I did uninstall several of the crappier pre-installed apps that came with my tablet.

Hi, your device will not brick, I can send you a test A511 recovery if you want. Worst that can happen is that recovery won't boot, but in that case you can simply put back recovery. Send me a private message and we can work something out.

Then it's of no use, unless you have a backup of your pre-installed apps. Removing apps from the /system or /flexrom partition is not recommended, and you gain nothing by it: You only gain space on read-only filesystems which you won't use in 99% of situations, and you've now broken OTA's for yourself as well, as OTA's will only install when apps are present unless you start modifying OTA files.
The 'correct' way to get rid of pre-installed apps is simply freezing them, either from the settings menu or with an app like Titanium Backup. This will make it seem like they're not there (so they don't use resources at all), but the APKs don't get removed.
So unfortunately, we can't use your dumps to restore devices to factory state. Unless, ofcourse, you've made a backup of the apps somewhere.

I just learned ADB, n successful install ur CWM, later will try to dump my stock Rom to u.
My stock Rom version 1.073 ww gen1
does it matter if the system apps have been frozen or do they need to be unfrozen first?
I have flashed that remove stock recovery mod so the stock rom doesn't keep overwriting cwm on reboot. Does that disqualify me? If not I'll dump my rom for you when I get home.
I'm on this rom version:
ro.build.pandora.id=Acer_AV041_A510_RV28RC04_PA_CUS1
ro.build.flexrom.id=Acer_AV041_A510_1.076.00_PA_CUS1
I unlocked bootloader,rooted,installed cwm then backed up my stock rom.Could i restore my stock rom then be able to send you those fills
and return to total stock.

i think he mean that the a511 recovery doesn't work properly....you can flash a zip, but nearly all other options brick the device
i have a a511 too with Acer_AV041_A511_1.028.00.EMEA_DE and can help with testing or something else
I have Acer AV041_A510_1.079.00_PA_CA. (Canada)
I have not done a thing to it because it is a replacement for the Galaxy Note I bricked trying to upgrade from GB to ICS, too early.
I might try again if I was sure I could get back to where I am, using your process.
I assume that your Root link is comprehensive but I also need reassurance on how to ADB.

No, as I understand, the only working methode to root the a511 is to bootloader unlock, flash the custom recovery and then the root.zip.
Maybe I'm wrong and there is another working way to root the device ?
The problem is simply, that we lost the stock recovery before we have a backup from it.
If we have another root way for a511, the backup of stock firmware is done in a few minutes and from this point we can test the a511 custom recovery from NoThrills.
To the A511 owners: Technically, if you have a install-recovery.sh file on your device, the device will always flash recovery back from the boot.img.
In theory: To test, one could simply overwrite the stock recovery with my Recovery (not the other ones, they will brick your device) and then when you reboot, your device will overwrite the recovery with the stock one again. So you really don't need a backup of the recovery partition.
As long as you don't let your device fully boot (so, stay in recovery) there's plenty of time to test if the recovery works or not. If it doesn't, simply reset your device and it will flash back the original recovery (again: provided there is a install-recovery.sh in your /system partition).
So again, if anyone is willing to test, let me know

I can't find a install-recovery.sh in /system partition on my a511. Search on root-explorer can't find one on the device.
Even NOT on /system/etc like on other devices.

Hello,
I have an stock Acer_AV041_A510_1.098.00_EMEA_CUS1, there we go for the files
Host file is not the stock version, it was edited by AdAway.
Can you make a version without recovery overwritting ?
I thinks a lot of people want to try some roms... just for testing...

Hey XDA ! =D
I'm still interested in installing Cyanogenmod 10 on my LG Optimus One P500h, but I want to make sure I follow the steps properly first - this is my first time installing a custom ROM, and when I heard it was possible to install Android 4.0 on the P500h, I performed a backup from ROM Manager, and I "bricked" my device a few days ago. XD
I wouldn't want this to happen again, but at least, I must say I have more experience now, and learned a lesson.
Did many searches on how to install CWM with Cyanogenmod 10, I found many different ways to do it, and I'm still unsure of which procedure follow.
Read the FAQ and that was really helpful.
I will list the procedure that I would normally try - please correct me if I forget anything:
0. Root the device
Done that already. I'm on Android 2.3. When I flashed the KDZ on my LG (and so to my surprise, got me updated from 2.2 to 2.3.3) , I've used V20A_00.KDZ, so I *assume* this is the second baseband.
1. Compact/Trim Cyanogenmod ROM
Downloaded CM10 here. This look correct: http://forum.xda-developers.com/showthread.php?t=1811325
January 8: Build 7/Final
I chose C10 over C11 because more things are compatible I believe - was it Bluetooth that did not worked under C11, but does on C10 ?
Anyways, that solve a known problem: many users said they loose network after the ROM installation. Shinobisoft confirmed it was because of the lack of space on the System partition, right ? Compacting the ROM would also fix problems for installing Link2SD ?
I've downloaded the tool "OOne ROM Editor" and opened it - it doesn't look complicated at all. What apps are safe to delete ? Will converting them to "user app" save space for system apps (I'm not sure - Where are the apps stored when defined as "User"? SD card rather than /System ?) ? Can I delete fonts without problems (I don't see why I can't keep ONLY 3-4 fonts, not 10) ? Then how much space will be left on the device ?
Read I cannot delete LatinIME.apk. Is this the default keyboard? 20MB is huge, there's no way to compact this file, right ?
Assuming there's like 10MB free, network will work, but I will have no choice but to use Link2SD to install apps fully on SD card, is this correct ?
2. Baseband stuff
Ehm, what are we referring to as "baseband" in first place?
All ROMs starting with CM7 are new baseband. If your device had Android 2.2 prior to flashing, you are on old-baseband. There is a patch for that also in the LG Optimus One FAQ on the first page, not sure which post off the top of my head tho. If your device had Android 2.3 on it then you have a new baseband device which shouldn't require any patches.

Allright, this should make this a lot easier - as I said, I originally was on Android 2.2, when I bricked the phone, I flashed "V20A_00" throught KDZ Updated, then I rebooted as 2.3.3, so I shouldn't do anything, right ?
In "About Phone", it's listed "Software Version: LG-P500h-v20a".
3. Install ClockworkMod Recovery
This look like the tricky part.
A lot of people on other sites said to use ROM Manager...
shinobisoft said:
First, serious word of advice. Stay away from ROM Manager. It does not handle this device correctly.
Click to expand...
Click to collapse
ROM Manager's way of flashing recovery is broken by design. Do NOT use it unless you are comfortable with rescuing your phone via ADB/fastboot like many people before.
Click to expand...
Click to collapse
Yes, ROM Manager is completely broken in this regard. It needs to download a signed ZIP and discard it and report an error when verification fails. Heck, ZIP format has even its own CRC check. What ROM Manager is doing (download whatever .IMG and flash it no matter what) is a nice WTF! Broken by design, go rewrite from scratch!
Click to expand...
Click to collapse
I don't trust the use of ROM Manager anymore on my device, and I'm not comfortable with using it again. I actually wonder: When I press VolumeUp-Home-Power, the phone perform a factory reset (Many people asked already why. This apparently mean that CWM is not installed).
But is it really installed? ROM Manager actually says: "Actual Recovery: ClockworkMod Recover 5.0.2.0". What? Am I supposed to press VolumeUp-Home-Power to verify, only to do another factory reset?
So what would the non-ROM-Manager method be ? I found this one here:
http://forum.xda-developers.com/showthread.php?t=1146566
I know about the Android Terminal Emulator already, and as a Linux user on PC, the commands "su", "cat", "chmod", "mount" are not unknow to me. I should be able to do this... That's not risky ?
So when CWM will be installed, I should be able to boot in it using "VolumeUp-Home-Power"; in theory, this is a bootloader, so if the ROM get screwed up, I *should* be able to access the bootloader to restore the ROM (I compare this to a PC BIOS - the OS is screwed, but BIOS remain accesible) ?
How could I explain that when I bricked my device with ROM Manager, I couldn't perform a factory reset, and only had access to Emergency Mode (I assume there is not such thing as a "Recovery Mode" on a P500h stock, new/untouched. The equivalent immediatly perform a factory reset) ?
All Android devices have a recovery partition. This is essentially a section of the device’s memory devoted to a very basic recovery system that is separate from the normal operating system. This is normally used by manufacturers for recovering a broken device (as even if the operating system crashes, the recovery image has a chance of still being access and used to reflash the operating system, etc.).
Click to expand...
Click to collapse
By default, the LG P500h recovery partition perform an immediate factory reset - CWM will be installed here, so I should be able to access it if the ROM freak out. But why couldn't I access the factory reset, when I bricked the device? That's what I wonder.
4. Access CWM and do a Nandroid Backup to SD Card
I will now have the files boot, cache, data, recovery and system, as well as"nandroid.md5" on SD card.
5. Wipe everything, clean SD Card
Perform "Wipe data/factory reset". This will format the /data, /cache, /sdext, and .android_secure
Select the "Advanced" option and on the next screen select "Wipe Dalvik Cache". Confirm the wipe.
Not necessary but I do it anyway, in the "Advanced" screen select "Wipe battery stats" and the confirm that wipe
For a clean installation I recommend formatting the system partition too. From CWM home screen select "mounts and storage". On the next screen select "format /system" and then confirm the format.
Press the back button until you are back in the CWM home screen. Select "Install zip from sdcard" and then select "Choose zip from sdcard". Browse your sdcard for the ROM to install and select it. Confirm the installation. Now wait for the install to finish.
Go back to CWM's home screen. Select "reboot system now" option and let the device boot. The initial boot will take a couple of minutes. Don't panic.
Click to expand...
Click to collapse
6. Partition SD card (?)
Is this at that point that I should do it, in CWM ? Or wait until I access Cyanogenmod and use a software on PC to partition ?
Assuming I don't partition, I guess I definitely will lack space for applications (Due to the space of Android 4.0) ?
I will do "Partition SD Card>EXT4 1024MB>Swap:64MB. Is this correct?
7. Install Cyanogenmod
Install ZIP from SD Card, choose the CM ZIP;
8. Install Google Apps
Once the install is done, I won't reboot and immediately install Google Apps, with "Install ZIP from SD card". I chose this package (Working on JellyBean):
http://forum.xda-developers.com/showthread.php?t=1917411
Then I should reboot in CyanogenMod and finally install Link2SD, I believe.
***
..Did I forgot anything ?
I *believe* that makes sense, but this is my first time installing a ROM - I doesn't look *that* hard, I did researches, but things can go wrong... :/
What should I do if I screw things up? Use KDZ Updater again ?
I'm still a little worried about that baseband thing, and the lost network connection.
Thanks for the input, cheers!
1) Use FlashImageGUI app to flash recovery/or use Recovery.IMG flasher by @shinobisoft
2) Forget the baseband stuff
3) Factory reset is the default action when you boot into stock recovery
4) If you partition SD card your data will be wiped anyway

1) I've checked FlashImage GUI, it look really simple to use. This is what I see now:
https://dl.dropboxusercontent.com/u/67605655/snap20140216_103936.png
For flashing a recovery image, should I select Clear Dalvik & Clear Cache ? Do I have to enable USB Debugging?
Where can I find the recovery image for CWM ? Here maybe: http://forum.xda-developers.com/showthread.php?t=1523050
I don't know, I would download CWM v5.0.2.7_Touch_p500-Build 4.zip.
Would the terminal emulator method would be easier (I still need to find recovery.img)?
Code:
$ su
# mount -o remount rw /system
# cat /sdcard/flash_image > /system/xbin/flash_image
# chmod 755 /system/xbin/flash_image
# flash_image recovery /sdcard/recovery.img
# mount -o remount ro /system
# reboot recovery
Since I have no Nandroid backup (I cannot do it until CWM is installed), what could I do if something goes wrong ?
2-3) Excellent, thank you.
4) I plan on partitionning, but at which point shoud I preferably do it?
Thank you, I appreciate the help - sorry for all the newbie questions.
1) Recovery image is in the zip fie itself. Extract it
The terminal method you're telling is just what FlashImage GUI does (notice the word 'GUI' )
2) Partition it whenever you want. Just backup your stuff before doing it.
3) As much I hate to say, the thanks button is there for a reason

Ok, so I've downloaded ClockworkMod_5.0.2.0_Recovery_ThunderG_Official here: http://forum.xda-developers.com/showthread.php?t=1523050
Extracted the ZIP and put the file recovery.img at the root of the SD Card (USB storage); so now all I have to do would be to start FlashImage GUI, select "Recovery Image", browse and choose the file recovery.img, then flash (I won't select Clear Dalvik & Clear Cache unless I have to (It's not selected by default, so I assume it's not require - although I've backed up my stuff already).
It's that simple?
I'm still in a learning stage, I bricked the device once with ROM Manager, so if that work, I should be more confident for the rest (I will take a Nandroid backup). Thanks for all the great explanations - Will press the thanks button soon
(How much thanks can I give per thread?)

Allright, I got it!
I saw the success message, then used the keys to reboot in recovery, that worked!
At the boot, I can read "ClockworkMod Recovery v5.0.2.0 E: Bad boot message "recovery ".
I believe the "E: Bad boot message "recovery " is a known issue, and but is not a problem - please let me know if I have to do anything about this.
So now I will compact the Cyanogenmod ROM (I don't know how much space I should free, but I'll try to free a decent ammount), and perform a Nandroid backup to SD card.
I believe the hardest/scariest is done. From now, if the ROM install fail, I could just restore the backup, I guess.
Are they any case when CWM is unaccessible (When I bricked my device, I had no access to stock recovery (which only perform factory reset) but just Emergency Mode. Why was that?) ?
Thank you, I will let you know about the rest.

That error message means you dont have SD-ext. Ignore it.

It's OK to thanks on multiple post.You just have a limit of 8 thanks per day.
ROM manager made anything inaccessible except emergency mode or fast boot mode for some people.
(When I flashed my Oone with CWM, ROM manager worked like a charm)
You can flash the ROM now

I appreciate the information;
It's quite akwards that ROM Manager broke everything (And I asked for a BACKUP - that's so broken, it brick the device when you want to BACKUP <__<) - when it rebooted, it was in Fastboot mode, and I never saw that mode before. Tried a few recommended commands without problems, but when I rebooted, I only had access to Emergency Mode.
What would be informative for me to know, is that ROM Manager seems to not only have screwed the ROM, but the stock bootloader as well. Weird.
Shinobisoft said we need to compact the CM10 ROM with his utility first, because the System partition is too small (Otherwise, I will have no network). I will do that, I have the tool, that doesn't look complicated.
From now, I am backing up my SD Card content (DATA is backed up too) with Nandroid present on SD, so I could start formatting, immediately followed by SD partitioning.
I guess I should be fine at that point - if anything goes wrong, I should have the option to restore the Nandroid backup.
Will let you know when I'll have the ROM compacted (Probably today).
EDIT: YAY !
Everything worked as we expected! I saved my SD Card on my computer, wiped it, partition it from CWM (EXT: 1024MB, SWAP: 64MB. I have a 16 Micro SD, class 4 (Can't afford higher class much, for now), then installed the compacted ROM. Immediately after, I installed Gapps, then rebooted.
That worked !! This ROM is DOPE ! Totally worth upgrading ! Blazing fast !! (Will be slower with apps installed, but well)
I also have a working network!
There is one thing that "failed", I cannot get Link2SD to work. It always says "cannot create mount script". I checked with Windows (I know by experience that I should absolutely not edit Unix partitions in Windows, I just check), and the FAT32 partition is the first, then I have a EXT4 partition, then the Linux-Swap, I don't know why it doesn't work.
I used Gparted to format the EXT4 partition to EXT2, but same problem, "cannot create mount script". What am I supposed to do ?
Thanks youuu !! =D
I'm really happy to have done this on my own, with help - I now have more experience with Android, I have experience with Windows, Linux OS and OS X, but never did I tried flashing a ROM yet.

How much free space is there on your /system partition ?
Link2SD should be working.

Hi,
Tanks for replying. out of 200mb, I have 70Mb free, but on /data. Last time i checked, /system was almost full (where can i check system size?).
Seems like lot of people have this link2sd issue.
@GameX2 use root explorer, it will tell you the remaining system space
@xu3sno or @ibub can you please help me ?

That's what I've thought, according to "Storage Analyzer", /sysem has as minimum free space of 84KB (!) and a maximum of 4.63 MB.
Did not experience any weird stuff, for now.
sd-ext folder doest exist at root, but it's empty.

Link2SD needs at least a MB to create mount scripts.
Delete some system apps like TerminalEmulator, CM File manager, Email, Exchange services.
Also use mini LatinIME.

Yes, that's right. You can check /system space by using Root Explorer. Or go to
Settings>About phone>Partition info.
I got 10+MB space left on /system partiton after trimmed the ROM and installed mini gapps.
You're right, Link2SD only works if there is 3MB, at least, left in system partition.

Once you have success with link2sd creating mount scripts, you can access at /data/sdext. Been a long time since I ran Jan 8 cm-10, but I seem to recall that partition info is not in settings/about phone. But link2sd will have it. Or there are other apps. When viewing storage info from settings menu, don't confuse internal memory with /system (190mb). Internal that is shown there is/data (200mb).

Geez, I went to 170MB of internal MB to 1GB, that's just plain insaneee !
Now I can use my LG P500h for an extra 2 years.

How Do I Install?
GameX2 said:
1) I've checked FlashImage GUI, it look really simple to use. This is what I see now:
https://dl.dropboxusercontent.com/u/67605655/snap20140216_103936.png
For flashing a recovery image, should I select Clear Dalvik & Clear Cache ? Do I have to enable USB Debugging?
Where can I find the recovery image for CWM ? Here maybe: http://forum.xda-developers.com/showthread.php?t=1523050
I don't know, I would download CWM v5.0.2.7_Touch_p500-Build 4.zip.
Would the terminal emulator method would be easier (I still need to find recovery.img)?
Code:
$ su
# mount -o remount rw /system
# cat /sdcard/flash_image > /system/xbin/flash_image
# chmod 755 /system/xbin/flash_image
# flash_image recovery /sdcard/recovery.img
# mount -o remount ro /system
# reboot recovery
Since I have no Nandroid backup (I cannot do it until CWM is installed), what could I do if something goes wrong ?
2-3) Excellent, thank you.
4) I plan on partitionning, but at which point shoud I preferably do it?
Thank you, I appreciate the help - sorry for all the newbie questions.

A bit new to installing a recovery and custom ROM on this LG Optimus One (very familiar with Sony phones though), apologies for the newbie-ness. I have all of the files as per this thread, but how do I install the GUI app without a file manager app?

Install some file manager from play store. In phone settings (not file manager) choose security. Then choose to allow installation from unknown sources. Then open your file manager, scroll to sdcard/downloads/ ,and click on flashimage GUI.apk. Installation process will start.

I guess I was thinking too much (or not at all!) Simplicity is the key a lot of times!
I tried all of the points in this thread and now this Optimus One has root, recovery and a new ROM. Thanks everyone! :good:
I was frustrated by the huawei encryption and decided to get rid of it once and for all.
At first I faced many bootloops but i finally figured out what was going on. Formatting user data through TWRP is not enough because after booting the device, encryption is still there. This happens because the kernel encrypts the device when booting up. Simply modifying the boot.img file to remove file encryption also doesn't work because you still boot into an already encrypted stock user data. So the answer was pretty obvious by now.
The trick is to format data using TWRP AND THEN boot to bootloader to flash a modified boot without encryption. So let's get to it.
How to create a modified boot.img without file encryption/dm-verity
1. Find and download your current firmware from Huawei Firmware Finder Dtabase (Team MT), or from a source that you trust. (Using a firmware with different cust version or a different update will most likely not work).
2. Download Huawei Update Extractor and use it to extract the stock boot.img file from UPDATE.APP
3. Download ASSAYYED_KITCHEN.
4. Place your stock boot.img file in the "WORK" folder of ASSAYYED_KITCHEN.
5. Launch ASSAYYED and select the 12th option (KERNEL/RECOVERY MENU) and then the 1st one (Unpacking Kernel).
6. The ASSAYYED options don't work for me so i did it manually. Go to your work folder and open the folder boot_unpacked\ramdisk.
7. You will see a file named "fstab.qcom", open it using WordPad.
8. Find the line:
Code:
/dev/block/bootdevice/by-name/userdata /data f2fs nosuid,nodev,noatime,discard,inline_data,inline_xattr wait,check,fileencryption
and delete ",fileencryption".It should now look like that:
Code:
/dev/block/bootdevice/by-name/userdata /data f2fs nosuid,nodev,noatime,discard,inline_data,inline_xattr wait,check
9. (This step is optional,follow it only if you also want dm-verity removed) Use the same method to remove dm-verity.
Code:
/dev/block/bootdevice/by-name/system /system ext4 ro,barrier=1 wait, verify
/dev/block/bootdevice/by-name/vendor /vendor ext4 ro,barrier=1 wait, verify
/dev/block/bootdevice/by-name/product /product ext4 ro,barrier=1 wait, verify
(Just delete the ",verify" part.)
10. Save the file.
11. Launch ASSAYYED and select the 12th option (KERNEL/RECOVERY MENU) and then the 2nd one (Packing Kernel).
12. Follow the instructions below to properly flash your modified boot.img and get rid of encryption.
Removing file encryption/dm-verity from the device
1. Unlock your device.
2. Flash this TWRP on AGS-W09 or the appropriate custom recovery for your device.
3. Boot to TWRP and FORMAT user data (note that it is very important to format data and not just wipe it). •WARNING• this will delete all your data!
4. Go back to the reboot menu of TWRP and select reboot booloader (it's important to not allow your device to boot into system yet).
5. Using fastboot, flash your modified boot.img that you created earlier.
6. Reboot your device (you might get a bootloop on the first boot but force rebooting your device again by holding the power button will fix that).
7. After booting up, your device should not be encrypted anymore.
8. You can now use the root method that you like to root your device and internal storage should be visible on TWRP. TWRP backup should also work normally.
How to fix Magisk modules not showing up on Magisk Manager (! /data/adb/magisk_merge.img mount failed error)
I am not going to get into the technical staff you can find more info here
Edit: As of Magisk 19.0, the following method becomes obsolete. Magisk modules should now work as expected without issues. This method now concerns those who want to stick to an older version of Magisk
1. Download f2fsfix-2018.9.2.zip provided by VR25 on the thread above.
2. Download all the magisk modules that you need to flash and place them on your device.
3. Download the latest Magisk uninstaller along with the latest installer.
4. Boot to TWRP and flash Magisk uninstaller. (If you don't have Magisk already installed, skip this step)
5. Wipe Davlik Cache.
6. Install the latest Magisk.
7. Wipe Davlik Cache.
8. Flash the "f2fsfix-2018.9.2.zip" immediately followed by your modules.
9. Reboot (it should take more than usual).
10. Open Magisk Manager and check your Modules. Hopefully they'll show as installed and function correctly.
Note: This method should also work on similar devices. Just make sure you know how to recover your device in case something goes wrong.
I can confirm this worked for me. I was able to run a full nandroid, but haven't tried to restore. Wasn't running any magisk modules, so haven't tried that part of the guide. Flashed Xposed in TRWP and installed greenify, etc Seems to be working. So far no errors. Be warned, this is like a restore. You'll be starting from scratch again.
Also thanks for the boot image trick Thanostsak. I couldn't find stock fimware for my version (AGS-L03) anywhere. He suggested to use the Magisk's boot image backup. Worked like a charm. Still looking for AGS-L03 stock if anyone has one, knows where to get one please post!

Glad it worked for you. Yes this is the downside. The device already comes with an encrypted userdata, so it needs to be formatted. So anything you do before that becomes obsolete. That's why this procedure is much more convenient when it happens after the unlock,when the userdata is wiped by the stock recovery to get a stock condition.

I just followed your detailed guide to my tablet and finished all the processes perfectly.
Working..Twrp, Magisk, removed encryption & verify from boot.img and from Data successfully.
A big THANKS for your guide, links and trick all in one post!!!!.
Thanks for the info.
I am new to android (but have jailbroken iOS for years).
I have received a Huawei MediaPad T3 AGS-W09 (AGS-W09C100B278) today.
I have managed to unlock and install TWRP 3.2.1 but also want to install SuperSU, but of course the filesystem is encrypted, which brings me here.
I have searched all over for Huawei MediaPad T3 AGS-W09 (AGS-W09C100B278) firmware which contains boot.img but cannot find it. Even the rom on the AGS-W09 thread on this forum doesnt contain the .img file. Am I missing something ?
Any help is appreciated.
Thanks again

I strongly suggest using Magisk to root your device instead of SuperSU. The good thing about Magisk is that everything happens systemlessly, so it doesn't matter if the kernel is encrypted in order of it to work. If you still want to use SuperSU though, my guide should provide all the info you need.
To answer your question you can find two OTA firmware updates for your device here. If that doesn't work (if the OTA updates don't include the boot.img file ) i will let you know how to use magisk to get a copy of your current boot.img

I have been looking down the Magisk avenue too.
My plan is, decrypt is then root it.
I did download those firmware files earlier but as you say, no .img files.
I have tried to follow a guide on youtube from rootjunky but got as far as running the info gathering piece to gather mount points, but it fell over. Don;t know if thats because I was using adb sideloading via TWRP .. ?
I attempted to run the commands from the batch file direct but no joy.
It would be really appreciated if you could point me to a guide to extract the img. It's my day 1 of this device and Android (already voided warranty from Amazon within 1 hour ha) but as I say, I have experience in most of what is needed from my iOS jailbreaking and bringing phones back from bootloops and the brink of bricks.
When you mention rooting with Magisk .. Can that be achieved in the state my device is in now, which is TWRP'd but encrypted ?
I also notice the "Ultimate Backup Tool, No Root Required" thread (cant put URL's yet as I'm a n00b member). Could that export my boot.img ?
I am done for today. I am working from home and it the device got delivered at 9:30 ish. I was hacking around with it all day and did about 20 min work. I'm fried now :-O

I get what you are saying. Going from iOS to android is a big step. Since the firmware files don't contain the boot.img and having in mind that you want to decrypt, getting a boot.img file is a must.
There are ways to get the boot.img without root but the ones i tried don't work. But there is an easy way that i know of that requires installing Magisk. When you flash Magisk from TWRP it roots your device. However, apart from rooting it also creates a backup of your boot.img in case something goes wrong.
Decrypting requires formatting your device, so Magisk will be removed too. So its only purpose for now is to provide you with a boot.img file.
Here is what you need to do
1. Download the latest magisk installer from the magisk threat
2. Save the file in your SD card (internal storage is encrypted)
3. Flash the Magisk installer from TWRP
4. Boot your device and navigate to /data
5. There should be a stock boot_xxx.img.gs file in there. Copy it to your storage, move it to a computer and extract it. You should get a boot.img file that you could use to decrypt.
6. Follow my guide to decrypt the boot.img and then flash it from bootloader
7. Since your device is now formatted from the decryption, you can choose the root method that you like.

Makes total sense. I just installed Magisk now from SD, thing is, the only spare SD I had was 128MB !! So I dont know if the .img was saved correctly. I will look into it tomorrow. My other large SD is corrupted but I have a 32GB one in the dashcam I will use tomorrow.
That leads me to a question. Is the auto created .img saved on the card or the internal storage ? I am assuming its card but I could not see it.
Will look more tomorrow.
Thanks

It is actually on the internal storage. Now that you are rooted you can use a root file explorer to get it. (128mb should be enough for this task)

Great! If you need anything feel free to ask.
Well... I followed your steps to remove force encryption and install Magisk, everything seems to be perfect. The Magisk and modules are funtional. However after reboot all modules are dispeared, but magisk is still recognized by magisk manager. I don't know where is the problem...
Model: AGS-W09
f2sffix version: 2018.10.9
magisk version: 17.2 (At first I used the latest 18.0 version, but after this problem appeared, I noticed that f2sffix-20181009 only support magisk version 17.2 or older, so I retry your method with magisk 17.2, but the problem remains.)

You should use the latest version of f2sffix (10.9) and then follow the procedure again. After your first boot follow VR25's recommendation and you should be good to go.
VR25 said:
Those getting everything broken after a second reboot, try the following workaround...
After the first reboot (right after installing), remove </sbin/.core/img/f2fs*bla*bla/service.sh>, </data/adb/magisk_merge.img> and </cache/magisk_merge_.img>.
Note that after doing this, you'll only be able to install modules and update Magisk from TWRP.

what if there is no fstab.qcom in kernel but stored in vendor/etc partition?
i've already edited the fstab, but still my system partition become ro (read only) when i made a change in system. all file manager error even previously has root.

I believe that what you are missing is after changing forceencrypt=footer into encryptable=footer you should also do a full data format through TWRP.

encryption is not a problem. since the first place already done with that data partition.
my problem is system partition, every time i made a change to system (for example deleting chrome.apk), something triggered that makes my system weird (magisk forceclose, all file manager become malfunction because system become read only). something lock my system partition if system change.
i thought change fstab.qcom <mnt_flags and options> ro,errors=panic to >> errors=continue (deleting ro/read only) will change my system behaviour, but it's not
Hi,
Finally I had time to finish my work on Xcover 4. I couldn't disable ForceEncryption by any flashable tool so I prepared 2 version of firmware (Oreo and Pie), both prerooted (Magisk) and free from Force Encryption. Everything except boot.img left untouched, both ROMs are BTU so no brand.
Just flash it with Odin 3.13.3. I recommend to flash CSC_BTU instead of HOME_CSC_BTU. HOME BTU should work as well but then probably You gonna have to format data with TWRP. CSC_BTU is already tested and there are no problems with Encryption.
After flashing just install Lastest Magisk Manager. SafetyNet Passed.
Oreo: G390FXXU4BSB3_BTU_G390FBTU4BSC1_Patched_By_Chamelleon

Code:

If You need TWRP (not necessary to flash this ROMs) flash this version:
TWRP: TWRP-3.1.1_SM-G390F_by_nemo-nemo
Code:
https://mega.nz/#!DIo1SSBT!w4dPPAF3BEcfQmsy7mANO33Lb5Gj4jzDkrrPfbH56uo
Working on both versions, Oreo and Pie. I didn't test backup and recovery options but flashing is working on both. ADB and MTP are not working.
To remove Security Log Agent notifications use SecurityLogAgent Disable. It will disable this annoying app completely.
Hello!
Can you explain because i would like only to root my phone in oreo 8.1 without losing apps and data. Is it possible with your method?
thank you for your answer.
Would anyone happen to know if I can use TWRP for SM-G390F's on SM-G390W's? (the only differences I know of between them are the supported LTE frequencies)
You can try to flash it, just backup your data and if something goes wrong just flash it with back with stock firmware.

Hi mates
very interesting matter. Will like to make it from a ubuntu 18.04 system? Did someone had tried it ?
Yea, it's a normal ROM so you can flash it with Heimdal.

thank you C for this fast answer .
Here is the second point :
IS this rom free from google , I mean enough
And the third
any visible amelioration from the XCOV 2 Model in battery standing . I do not care about photos for my purpose .
Only memory, increased by SD, and lasting time
It's completely stock rom without any modifications except integrated Magisk and disabled force encryption. Rest is untouched.
I don't understand what file I should use to flash with Odin.. in the link you posted sends to a download of a zip file of almost 2gb in which there are many files, so from those files which one should I set in Odin?
Flash it like any other stock ROM:
BL file in BL
AP file in AP
CP file in CP
CSC_BTU file in CSC
Everything works great:]
Thanks man.
Hi Chamelleon and thanks for all the effort you've made already!
I successfully flashed the Pie variant of the two ROMs and got it to work. However, turned out that in an app that I'm developing, for some reason, when my device is equipped with G390FXXU4CSF9_BTU_G390FBTU4CSFA, the app doesn't behave in the same way as when G390FXXU4CSF9_ G390FXEO4CSFA has been installed. That's why I would like to be able to root the XEO-version of the firmware. Moreover, there will be many other non-rooted devices equipped with the XEO-version using the app in the near future.
Having flashed my device with G390FXXU4CSF9_ G390FXEO4CSFA, I tried installing the version of TWRP you have provided but I can't figure out how to install Magisk from there. By default, TWRP can't find the Magisk zip-file that I push onto the device. I tried formatting data, as per this post. The post lead me to believe that the files could be found after formatting but even though there were now plenty of TWRP-related folders, I couldn't find the zip. And as ADB and MTP don't seem to work in recovery mode, I'm unable to get the zip file on board after formatting. Booting to system doesn't work either after allowing modifications for TWRP, which might be due to dm-verity preventing boot, but franky I don't understand much of that topic.
You mentioned that you couldn't disable Force Encryption with any flashable tool. Is that the reason why TWRP (or any other tool) couldn't reach the zip file for Magisk?
This is the first time I've attempted rooting a phone so my knowledge regarding the topic is pretty basic.
So I suppose preparing a prerooted and Force Encryption free version of the firmware might be a possibility? I have no idea how to patch a ROM though. Any advice on how to proceed?
Hi, I had no time to play with this during Christmas. If you send me your boot.img I can modify it for you. If You just flash magisk with TWRP it will root your phone but after first reboot whole data partition will be encrypted again and you wont be able to flash anything with twrp or modify data partition without full wipe. For some unknown reason this and probably more Samsung models have different structure of files responsible for encryption and because of this none of pre-made patches are working. Only manual kernel modification can safe from encryption, at least for now.
I'm not a developer so I don't know how to prepare patch for this to allow anyone to flash it, I just found few lines of code in kernel You need to modify to disable encryption.

Hi, I really appreciate the help!
I sent the boot.img to your paypal donation email. Let me know if you want me to send it to you some other way.
How to flash firmware on linux?
I know that i have to use heimdall but how to load these files into the program because filenames say basically nothing to me.
Thanks in advance.
Also does it delete user data?

1. Flash clean ROM, same as boot you send me)
2. Enable OEM Unlock in Developer settings
3. Flash patched boot with Odin as AP/PDA.
4. Install Magisk Manager app
5. Install TWRP and format data partition, option where you need to type "YES"
6. Reboot system and then back to TWRP. If you can mount data and there are no errors it's done.

Sorry but I never had a chance to use Heimdall. You can't dirty flash this because when your phone is encrypted and you can't replace kernel corrupting data.
But do I lose my data(Apps settings etc.)?
I'm OK with setting everything up back ,but it would be cool if it kept data.
(I'm going to use other computer that has windows on it btw, and I'm going to flash it with odin)
If your data partition is encrypted you gonna corrupt it by changing kernel. It means You wont be able to access, so yes, you will loose it.
What you mean by encryption some option in the Android or what?
If that's what you mean I haven't set up anything like this
Hello everyone.
If you want to have a recovery with the ability to backup/restore, this instruction is for you.
Here are recovery, while they do not know how to encryption of data section (I hope we will have such ones sometime).Yes, recovery already patched by magisk 25.2
Download the patch, copy it to the SD card (if you have it) or to a USB flash drive, for firmware by otg.
We set the recovery in fastboot mode with the command:
fastboot flash boot (recovery name).img
We load into the recovery, flash the patch, and make FORMAT DATA.
Attention!!!This will delete all your settings and installed programs, including deleting everything from the internal memory.
After that, we boot into the system, configure and "rejoice", now the recovery will see data and, accordingly, internal memory.
And yes, if you have a security thing, this procedure disables the encryption of your data
COMPLETELY, THAT IS, COMPLETELY.
Oh, I forgot, although I think it's clear by the name of the recovery, they (recovery) are designed for firmware on Android 12.
Download files:
RECOVERY
Guys, one jamb got out here, my system has been transferred to RW, and I checked the script on such a system. As it turned out, the script does not work on the stock system. So, in order for it to work normally, you need to first transfer the system to RW
Any chance to explain step by step?

one is TWRP recovery and the other is Orange Fox recovery, choose which one you want to use, just flash one of them.
Hey does twrp/orangefox actually work on this phone. I've heard that those are currently under development. And does flashing these .img require wipe data or can they work with sd card or OTG?

Recovery can work with both sd and otg. While they cannot decrypt the data, but if you transfer the system to RW, and flash the patch to disable encryption in the system, then everyone will see the recovery.
Who has a system in RO, you can use these, checked, it also works
[A/B][A-ONLY][SCRIPT][READ-ONLY][EROFS][ANDROID 10+] Universal Disable Force Encryption for RO and RW "NEO STABLE"
Disable Force Encryption NEO Do you all know what DFE is? no? Anyway. Basically, your device has an encrypted data section "/data" by default. Let's look at the advantages of google's solution that we will lose after disabling encryption: -...

Can it backup anything such as boot.img, vendor etc?

Probably you can, but why. A backup of the datа section is enough for normal recovery. Of course, you can also make a backup of the super section if you changed something in it.

After using this patch my device doesn't know how to be case sensitive, which makes some apps have weird errors with read and write functions

This is clearly not because of the patch, I have put it on for a long time, and there are no problems. Yes, and he only disables encryption in the system, how can he influence this.
