Hi, is there a way to do a nandroid +ext backup directly to pc?
i'm trying to change my sd card (2gb) to a bigger one (8gb). i heard i have to backup and restore the nadroid + ext backup to preserve the application installed, i'm using app2sd. rooted p500 optimus one.
I can acces the phone in recovery mode but if i do a nandroid +ext backup i have a error: "Error : Run 'nandroid-mobile.sh' via adb!"
this is probably because i don't have space to do the backup in the sd.
i want to do the backup directly to pc using adb.
i started with ('im using ubuntu)
Code:
cd *adb folder*
sudo su
./adb shell
and then i went to the nadroid backup help via adb:
Code:
/ # /sbin/nandroid-mobile.sh --help
Usage: /sbin/nandroid-mobile.sh {--backup|--restore|--getupdate|--delete|--compress|--bzip2:ARG|--webget:URL|--listbackup|--listupdate} [options]
--help Display this help
-s | --subname: SUBSTRING In case of --backup the SUBSTRING is
the prefix used with backup name
in case of --restore or -c|--compress|--bzip2 or
--delete SUBSTRING specifies backups on which to
operate
-u | --getupdate Will search /sdcard/download for files named
*update*.zip, will prompt the user
to narrow the choice if more than one is found,
and then move the latest, if not unique,
to sdcard root /sdcard with the update.zip name
It is assumed the browser was used to put the *.zip
in the /sdcard/download folder. -p|--path option
would override /sdcard/download with the path of your
choosing.
-p | --path DIR Requires an ARGUMENT, which is the path to where
the backups are stored, can be used
when the default path /sdcard/nandroid/mem=471M
needs to be changed
-b | --backup Will store a full system backup on /sdcard/nandroid/mem=471M
One can suppress backup of any image however with options
starting with --no[partionname]
-e | --ext Preserve the contents of the ext partition along with
the other partitions being backed up, to easily switch roms.
-r | --restore Will restore the last made backup which matches --subname
ARGUMENT for boot, system, recovery and data
unless suppressed by other options
if no --subname is supplied and the user fails to
provide any input then the latest backup is used
When restoring compressed backups, the images will remain
decompressed after the restore, you need to use -c|-compress
or --bzip2 to compress the backup again
-d | --delete Will remove backups whose names match --subname ARGUMENT
Will allow to narrow down, will ask if the user is certain.
Removes one backup at a time, repeat to remove multiple backups
-c | --compress Will operate on chosen backups to compress image files,
resulting in saving of about 40MB out of 90+mb,
i.e. up to 20 backups can be stored in 1 GIG, if this
option is turned on with --backup, the resulting backup will
be compressed, no effect if restoring since restore will
automatically uncompress compressed images if space is available
--bzip2: -# Turns on -c|--compress and uses bzip2 for compression instead
of gzip, requires an ARG -[1-9] compression level
--webget: URL|"" Requires an argument, a valid URL for an *update*.zip file
If a null string is passed then the default URL is used
Will also create an update.MD5sum file and update.name with the
original file name.
--nameserver: IP addr Provide the first nameserver IP address, to override the default
--nameserver2: IP addr Provide the second nameserver IP address, to override the default
--webgettarget: DIR Target directory to deposit the fetched update, default is
/sdcard
--norecovery Will suppress restore/backup of the recovery partition
If recovery.img was not part of the backup, no need to use this
option as the nandroid will not attempt to restore it, same goes
for all the options below
--noboot Will suppress restore/backup of the boot partition
--nodata Will suppress restore/backup of the data partition
--nosystem Will suppress restore/backup of the system partition
--nocache Will suppress restore/backup of the cache partition
--nomisc Will suppress restore/backup of the misc partition
--nosplash1 Will suppress restore/backup of the splash1 partition
--nosplash2 Will suppress restore/backup of the splash2 partition
--defaultinput Makes nandroid-mobile non-interactive, assumes default
inputs from the user.
--autoreboot Automatically reboot the phone after a backup, especially
useful when the compression options are on -c|--compress|
--bzip2 -level since the compression op takes time and
you may want to go to sleep or do something else, and
when a backup is over you want the calls and mms coming
through, right?
--autoapplyupdate Once the specific update is downloaded or chosen from the
sdcard, apply it immediately. This option is valid as a
modifier for either --webget or --getupdate options.
-e|--ext Save the contents of ext partition in the backup folder too.
Enables to keep different sets of apps for different ROMS and
switch easily between them.
--save: ROMTAG Preserve EVERYTHING under ROMTAG name, a composite option,
it uses several other options.
--switchto: ROMTAG Restores your entire environment including app2sd apps, cache
to the ROM environment named ROMTAG.
-q|--quiet|--silent Direct all the output to the recovery log, and assume default
user inputs.
-l|--listbackup Will search the entire SDCARD for backup folders and will dump
the list to stdout for use by the UI. Should be run with --silent
--listupdate Will search the entire SDCARD for updates and will dump
the list to stdout for use by the UI. Should be run with --silent
now the option is this, how can i change to path to mmy computer hard drive
Code:
-p | --path DIR Requires an ARGUMENT, which is the path to where
the backups are stored, can be used
when the default path /sdcard/nandroid/mem=471M
needs to be changed
what would be the complete command to do the ext + nadroid backup via adb?
tried to do only nandroid and the fix apk uuids with no luck.
any help?
ok i fckd up everything and now it won't see the app on the sd on both sds.
i ended up reinstalling all the apps manually, all the data were saved.
just one thing: i lost memory on the internal memory, i had 30 mb free with 121 apps installed and now i have 20 free with 56 installed, how is this possible?
i deleted manually with root explorer the data folders i don't need in the /data folder but the notification of low memory didn't disappear.
how to solve?
solved, formatted sd and reinstalled everything + titanium backup
thanks for helpin -_-'
Tired of backup, wipe, flash, backup, wipe, restore, ... just to try a different ROM?
Today we will cook a nice tasty dual-boot for the TF700T. You will have two separate environments with different ROMs, apps and data that share only the common Linux kernel binary.
Difficulty: medium. No programming skills required, but not for noobs.
Ingredients
1 TF700T running a rooted stock-based ROM with busybox and a kernel with preinit support (hint: -that kernels work fine )
1 PC running Linux with a microSD card reader
1 fast microSD card with at least 4 GB
1 CyanogenMod 10.2 nightly ZIP (should also work for other ROMs - post your results)
1 seasoned chef
Time required: about 30 to 45 minutes.
Directions
Preheat oven to 220 degree celsius ... oops, wrong recipe.
If done right, the internal ROM and its data are perfectly safe. But I assume you have a backup nevertheless - don't blame me if anything goes wrong.
Prepare the microSD card
Insert microSD card into PC card reader. Using gparted, create and format 3 primary partitions:
p1: fat32, this will be your external sdcard as before.
p2: ext4, this will become /data
p3: ext4, this will become /system
Make sure to align the partitions to MiB, or even better multiples of 4 MiB. This may improve I/O performance.
In most cases you can simply shrink the existing FAT32 partition and then create the remaining ext4 partitions.
Partition 3 should be 700 to 800 MB - anything bigger is a waste of space, and anything smaller than 500 MB might cause problems.
Partition 2 will be your whole "internal storage" for the second operating system, so size it according to your storage needs for apps, app data and the emulated /sdcard.
I am using a Samsung 16 GB card with the following partition sizes:
p1: ~ 8 GB
p2: ~ 6 GB
p3: ~ 800 MB
Prepare the new ROM
Before installing the second ROM to the microSD card, the ZIP file must be slightly modified. I assume you know how to unpack and repack a ZIP file and how to use a text editor - if not, find a tutorial elsewhere. .
Note: This step can now be automated, see http://forum.xda-developers.com/showpost.php?p=47333729&postcount=31
To do it manually:
First, extract boot.blob and set it aside for later. Then carefully remove it from the ZIP. Second, find META-INF/com/google/android/updater-script and modify it:
Replace all occurrences of mmcblk0p1 with mmcblk1p3. I had 3 occurrences in CM's updater-script - make sure you modify all of them, otherwise your internal ROM might not survive the installation. This change will redirect the installation to the external microSD card. Finally, remove the line that says package_extract_file("boot.blob", ...) near the end - it would overwrite the kernel and we don't want that.
Now we need to add the WiFi modules. These are compiled directly into the CM kernel, but separate modules in the stock kernel.
Get the kernel modules from your running ROM - they are in /system/lib/modules (e.g. using adb pull /system/lib/modules), and copy at least these two into the ZIP into /system/lib/modules:
cfg80211.ko
bcmdhd.ko (note: for TF300, I think you need bcmdhd_29.ko instead)
Finally, repack the ZIP, mount the first partition of your microSD card and copy the ZIP file there.
Extract the ramdisk files
Note: This step can now be automated, see http://forum.xda-developers.com/showpost.php?p=47333729&postcount=31
To do it manually:
Here comes the tricky part. You need to extract the ramdisk from the boot.blob you saved from the ZIP file in the previous step.
To do that, you need tools that may not be in every household, but should be easy to find using your favorite search engine. In case you have trouble finding and/or compiling them, you can find the result of this step in post #2.
First we need to unpack the blob (https://github.com/AndroidRoot/BlobTools):
Code:
blobunpack boot.blob
This will create boob.blob.LNX. This is the boot image, from which we need to extract the ramdisk (https://github.com/huaixzk/unpackbootimg):
Code:
unpackbootimg -i boot.blob.LNX
This will create several files, we are interested in boot.blob.LNX-ramdisk.gz - copy this one to your tablet, e.g. into /sdcard. For example:
Code:
adb push boot.blob.LNX-ramdisk.gz /sdcard/
Prepare the preinit script and the ramdisk files
Note: This step can now be automated, see http://forum.xda-developers.com/showpost.php?p=47333729&postcount=31
To do it manually:
On the tablet, open a shell in a terminal app or use adb shell and become root (su). Run the following commands:
Code:
mount -o remount,rw /system
cd /system
mkdir boot
cd boot
mkdir rootfs_cm
cd rootfs_cm
gzip -d -c /sdcard/boot.blob.LNX-ramdisk.gz | cpio -i
The first line makes /system writable until the next reboot. The next few lines are self-explanatory. The last line uncompresses the ramdisk image we created in the previous step and extracts the contained files. We are doing this on the tablet itself to preserve the file permissions.
Now modify the file fstab.cardhu (one of the files just extracted).
Replace mmcblk0p1 with mmcblk1p3 and mmcblk0p8 with mmcblk1p2.
mmcblk0p2 can stay as it is, it's the /cache partition that is only used to communicate with the recovery.
Next we need to make sure the WiFi modules that we added are loaded at boot time. Edit init.cardhu.rc and find the "on boot" line. Add below (indentation is important):
Code:
insmod /system/lib/modules/cfg80211.ko
insmod /system/lib/modules/bcmdhd.ko
Near the end of init.cardhu.rc is another reference to mmcblk0p8 that needs to be modified to mmcblk1p2 - near "service setup_fs".
Finally create the file /system/boot/preinit with the following content:
Code:
#!/system/bin/sh
# preinit: only /sys and /system are mounted (ro), / is still rw
PATH=/sbin:/system/bin:/system/xbin
# auto-detect rom2sd
if [ -d /sys/block/mmcblk1/mmcblk1p3 ]; then
echo "\nsystem/boot/preinit: mmcblk1p3 detected, setting up for ROM2SD.\n"
cp -a /system/boot/rootfs_cm/* /
fi
Make sure to make it executable:
Code:
chmod 744 /system/boot/preinit
This script is run by the kernel before the real Android init. It. detects if a microSD card with 3 partitions is inserted, and if yes, it copies the files for the CM root filesystem into the ramdisk. The following Android boot procedure will then mount /system and /data to the partitions on the microSD card and the whole operating system will run from the microSD card. If no card is inserted, nothing is modified and the normal internal ROM is started.
Flashing the ROM
Insert your microSD card into the tablet, boot to TWRP and flash your modified ZIP as usual - but disable signature checking because we didn't sign the modified ZIP.
Recovery
The recovery doesn't know about the external ROM, so you can't use the recovery to backup or restore its system or data. I prefer using the PC for that anyway.
Booting
To boot from internal storage, make sure the microSD card is not inserted when you start the tablet (you can insert it as soon as the boot animation appears). To boot from the microSD card, make sure it is inserted before you turn the tablet on.
That's all. Add more microSD cards for triple-boot, quad-boot, etc.
Notes
My kernel currently has not enabled SELINUX in the config, but CM appears to work anyway.
Update: -that6 enables SELinux.
Shortcut
In case you don't want to extract the CM ramdisk from the blob yourself (or you have trouble finding/compiling the tools to do so), you can try using mine - from my unofficial build of cm-10.2-20131024: View attachment boot.blob.LNX-ramdisk.gz

It is a nice detail instruction for new users like me. I really like it a lot and I can use some information from your post for my system2sd... However, maybe I misread your post. I don't see any information about repack the blob when you are done modifying the fstab.cardhu. I know a little bit of ramdisk and can get around it but that information will help the first time users... Just my opinion and thanks for sharing a valuable information to us...

That's because you don't need to repack the blob or reflash the kernel - I wanted to simplify the procedure, so I added preinit support to the kernel's ramdisk a few months ago. You just put some files in /system/boot and the kernel will run your preinit script that modifies the ramdisk at boot time.
Just remember that if you reflash your internal ROM, you have to recreate the /system/boot stuff.

You should be fine until I enforce SELINUX. But I haven't finished the policies yet. Still have some issues to iron out with that. Have about 90% of them done, I think.. lol
Just out of curiosity, will this only work with primary partitions?

It should also work with logical partitions if you modify the partition numbers accordingly. And please remove the full quote of my guide from your post, we should not emulate an Outlook-style mess in the forum.

Is there any chance *someone with the required skills* could port bootmanager to our device?
BootManager
it would be the best, considering that your method uses the same load-from-sdcard thing.
Just curious thats all.

Looks like commercial software, so ask the devs of that app.
Here is an experimental flashable zip file that redirects the TWRP recovery to the ROM2SD environment. It doesn't really install anything to storage, it just reconfigures the device nodes so that the recovery is tricked into accessing the system and data partitions on the microSD card instead of internal storage.
It works so well that after "installing" this, a following ROM install that unmounts and formats /system and installs itself to /system on mmcblk0p1 will actually be installed on the microSD card, so you don't need to replace the partition names in the updater-script any longer (but you still need to comment out the blob flashing line for now or reflash my kernel after the ROM).
It also works so well that after "installing" this, you don't see your internal /sdcard any longer, so put whatever you want to flash on the first partition of the external microSD card.
"Installing" the script again will undo its actions, so you can toggle back and forth between external and internal storage.
Warning: I tested this only once, and the script does not have any error handling - if the inserted microSD is not prepared for ROM2SD, behavior is undefined - most likely the recovery will complain that it can't mount system or data. Use this at your own risk and make sure you have backed up all valuable data and your ROM, just in case.
View attachment dev-rom2sd.zip
The script also contains a nice example how to output text from a shell script to the recovery console. It shows a list of device nodes so you can see what the script did (the device numbers of mmcblk0p1 and mmcblk1p3 are identical).

I've never tried PA but it may work if you use my kernel and modify the preinit script accordingly (my kernel contains a stock-compatible ramdisk, so you need to copy the PA ramdisk to / if the microSD is *not* inserted).

sorry for such a noob question but how do you compile the zips from the git links to an executable? Or does the bloobtool and unpackbootimg able to run from its extracted zips? slightly new to this...

You need to compile the blobtools on git. extract the .zip and run blobunpack on the .blob then abootimg -x on the boot.img.to repack: abootimg --create *new-bootimg* - k *zImage* -r *ramdisk*, then repack the .blob

You don't use git to compile, you use it to manage the source code.
To compile the source code, you need the appropriate development tools installed (I think it's called "build-essential" on Debian-like distributions) and run "make" in the directory with the extracted source code.

Wow this is too complicated to compile, having to setup and run debian on usb. Guess I can't try out rom2sd
So here you come. To read and perform this tutorial, you obviously need a first hand experience on flashing a ROM and/or kernels. Otherwise this tutorial and my efforts to get you a device with two OSes running might end up giving you a bricked device. So, if you're hearing the terms "flashing" or 'kernels' for the first time and thinking it's kinda good food, then bro, just go and taste those first.
Something's to remind before we gonna dig deep into this tutorial->

2> The warranty of your device will be voided after this if it isn't already after rooting. For MI users, the good news is that you can reclaim it by just flashing the fastboot ROM for your device.
Enough lectures. Bro let's get to work.
This you'll be needing =>
1> One working Windows PC(because I doesn't know any replacement of bootimg.exe on any other OS. If you know, then let me).
2> A class 10 memory card ( I recommend 32GB for the spaces)
3> A custom ROM and kernel for your phone(the second os)
4> Any custom CWM based recovery installed.(since TWRP is most popular, I will demonstrate using it. You can use any other you want overall process will be the same)
5> ADB, fastboot and the device drivers (easily found in XDA)
PART 1: MODIFYING THE BOOT
At first, how does your device boots up? What are the partitions called /data and /system? The answer is quite simple. It's your kernel that points out the location from where the OS should be picked up. So for booting into the second OS we need some modifications to it at first.
Search and download bootimg.exe on XDA, I'll post a link later. Create two folders. Name them "Internal OS" and "External OS" respectively. Put the zip file of the OS you're currently using to the first one and the OS you're gonna use on the external storage to the second one. Rename the second OS to originalExternalOS.zip. Extract originalExternalOS.zip. Pick the boot.img file from the root of the extracted folder and move it to a new folder named "boot2". Extract the IMG using bootimg.exe. Navigate to the initrd folder and you will get a file named 'fstab".
Basically it's the file that tells the kernel which partition does the OS resides in.
Open the file in your favourite text editor.
Replace every instance of the first line with the second one:
/dev/block/bootdevice/by-name/system => /dev/block/mmcblk1p2
/dev/block/bootdevice/by-name/userdata => /dev/block/mmcblk1p3
/dev/block/bootdevice/by-name/cache => /dev/block/mmcblk1p4
Save the file without giving any extension to it. Repack it using the same tool. You'll have boot-new.img and boot-old.img. Rename boot-new.img to boot.img and replace the one in the root folder with this. Basically what we're doing here is replacing the old boot.img with the modified one.
For your knowledge, blocks are the partitions of any storage you have on your device. For example, your internal storage is partitioned to near about 30 different blocks each starting with prefix "mmcblk0p". We here just told the kernel to load the OS from the blocks mentioned. We'll be creating these blocks in the external SD card next.
PART 2: PARTITIONING THE SD CARD
Connect your device with the memory card inserted to your PC. If you haven't installed fastboot, ADB, and the drivers, do it now.
READ THE FOLLOWING CAREFULLY
Reboot the device to recovery mode. Type the commands in cmd:
Code:
adb shell
parted
unit MB
print
quit
umount external_sd
Read and store the minimum and maximum capacity of your card. Since different cards will have different capacities I will point it as variable MIN_SIZE and MAX_SIZE. You'll need to calculate and put the values in the commands. Now type the following commands on cmd:
Code:
parted /dev/block/mmcblk1
rm 1
//START_BLOCK = MAX_SIZE - 5000
mkpartfs primary fat32 MIN_SIZE START_BLOCK
//SYS_START = START_BLOCK+1
//SYS_END = SYS_START + 1200
mkpartfs primary ext2 SYS_START SYS_END
//DATA_START = SYS_END+1
//DATA_END = DATA_START + 3500
mkpartfs primary ext2 DATA_START DATA_END
//CACHE_START = DATA_END + 1
mkpartfs primary ext2 CACHE_START MAX_SIZE
//We have partitioned the memory card. Let's format them. Ignore all "Do you wish to continue" question in the next commands as we're already mentioning yes.
mkfs yes 1 fat32
mkfs yes 2 ext2
mkfs yes 3 ext2
mkfs yes 4 ext2
quit
//Now they are almost ready. Just make the newly created blocks readable by the OS.
make_ext4fs /dev/block/mmcblk1p2
make_ext4fs /dev/block/mmcblk1p3
make_ext4fs /dev/block/mmcblk1p4
//Now you get where does the blocks come in the kernel right?
exit
//You've covered up the hardest part. Let's get some coffee and cheeerssss.
PART 3: MODIFYING THE NEW OS
You've left the OS extracted in the "External OS" folder right? It's time to do some magic in it. We're gonna tell the OS to be installed in the blocks we created just like the kernel. But wait, where does the OS know before installing where it should get installed? Well, the answer hides in the updater-script in the folder META-INF > com > google > android. Navigate yourself in it. Open the updater-script file in your favourite editor ( I use notepad++ ) and modify it in the same way as the kernel.
Replace every instance of the first line with the second one:
/dev/block/bootdevice/by-name/system => /dev/block/mmcblk1p2
/dev/block/bootdevice/by-name/userdata => /dev/block/mmcblk1p3
Leave the /dev/block/bootdevice/by-name/boot as it's the fundamental block and we can't replicate it. Don't think for the /cache partition as we've already done that in the boot.img file. Now navigate to the root of the folder where you extracted the External OS. Select all files, add them to a zip file using WinRAR. Name the file to newOS.zip. Open newOs.zip and originalExternalOS.zip with WinRAR and compare them if you find any change in the folder tree. They must and they should be exactly the same. You're 80% done.
PART 4: MODIFYING THE RECOVERY
We often flash many zips including very popular Xposed and other mods to our OS right? They also look for the /system partition. So what are we gonna do? Modifying each of them? Nah. Let's modify where they get which one the /system is. The recovery. Extract the img of the recovery you're using with the same bootimg.exe. Modify exactly the same things. I.e.
Replace every instance of the first line with the second one:
/dev/block/bootdevice/by-name/system => /dev/block/mmcblk1p2
/dev/block/bootdevice/by-name/userdata => /dev/block/mmcblk1p3
/dev/block/bootdevice/by-name/cache => /dev/block/mmcblk1p4
in the following files : initrd/fstab.qcom
initrd/etc/recovery.fstab
initrd/etc/twrp.fstab(For TWRP only)
Save them. Repack. And you got your recovery-new.img and recovery-old.img. Put recovery-new.img and newOS.zip in the same folder. Now wake up, it's time for some action.
PART 5 : INSTALLING THE OS
Open cmd in the folder where newOS.zip resides. Reboot the devixe in fastboot mode. Type the following commands:
Code:
adb push newOS.zip external_sd
fastboot flash recovery recovery-new.img
fastboot boot recovery
Now your device should boot up in recovery mode. To check if everything has gone fine mount system using TWRP. Use twrp's built in file manager and navigate to system folder. It's empty? Yup. You've done a great job. Now flash the newOS.zip using TWRP and your device should boot up in the new OS. To cross check again remove the SD card and try to boot. If you're headed towards recovery or bootloop after that then it's a win. Put the SD card back again and watch the new OS to boot.
PART 6: SWITCHING BETWEEN THE TWO
Extract the boot.img from the "Internal OS" zip file and put it together with recovery-old.img. To check if your old system is untouched type the following commands in fastboot mode:
Code:
fastboot flash recovery recovery-old.img
fastboot flash boot boot.img
fastboot boot system
Your device should take you back to the old one. Surprised? Now let's make a switch between the two. There are two methods.
METHOD 1: USING FLASHIFY
Create two folders in your SD card. Put boot.img and recovery-old.img to one and boot-new.img and recovery-new.img to the other. To switch to the external OS, just flash boot-new.img as boot and recovery-new.img using flashify. Ignore reboot now dialog and reboot directly to the system. To go back, first install flashify in the new OS and flash boot.img and recovery-old.img. Easy right?
METHOD 2: USING ZIPS
I'm gonna tell you that tomorrow as I can write no more today.
More to come....

justzzshadz from MIUI forum for this revolutionary concept. @iamsubhranil for adding TWRP, Flashify support and completely rewriting the tutorial.
This Was done Using A G935F international
First... just like any other device .... we need to identify the partitions, and what partition contains WHAT...
1. For the Marshmallow .. they added more security to the sd card and permissions. Instead of the sd being reffered to as SD CARD... its now something like xxxx-xxxx and requires special permissions (permissions.xlm edit) to r/rw.
Root explorer or equivalent needed..
(with root permissions)
2. Navigate to these two directories... you will need these folder names to pull from and push to .......LATER.......
Directory A.
Dev/block/platform/155A0000.ufs/by-name
marshmallow did something useful!
They Gave the partitions and the block names to you in the .UFS/by-name folder (see screenshot)
Your filesystem may not contain A folder named 155A0000.ufs (im unsure if this folder is a variable at this time)
If it does... cool... if not... look for YOUR folder name .ufs and make note of it...
For all you terminal users...
(using 3C system Tuner Pros Terminal Saves some time with that copy and pasting)
Line command:
ls -l /dev/block/platform/155a0000.ufs/by-name
This will identify the partitions inside of terminal emulator.
This is the path for your INDIVIDUAL SD CARDS!!
EVERYONES will be different...
again... find the folder name... and keep note of it...
in my case... my SD Card Name is ... 7C8B-46B3 (see screenshot 1)
DIRECTORY B.
FROM ROOT : Navigate to
B. /storage/7c8b-46b3/DCIM [/B](dcim a folder i made on my sd) You can do the same or use your own filepath if you know how.. if not... then make it...
Once these two folders are identified.. you can begin to pull the partition images...
DD OF=/dev/block/sda14 <<<---- this is the system partition SDA14
OF=/Storage/xxxx-xxxx/(the folder you want it in)/system.img bs=4096
DD Command List!
SYSTEM
dd if=/dev/block/sda14 of=/storage/XXXX-XXXX/DCIM/system.img bs=4096
BOOT
dd if=/dev/block/sda5 of=/storage/7C8B-46B3/DCIM/boot.img bs=4096
RADIO
dd if=/dev/block/sda8 of=/storage/7C8B-46B3/DCIM/radio.img bs=4096
After You Have Your Images
ONCE YOU HAVE THE BOOT.IMG and the system.img...
You can choose to make a flashable zip... or you can convert the files into TAR files...
use with comsey odin ...
THIS Guide Will Further you On if Your Looking to Make Odin Flashables!

After a week or 2 i can get back home and test it , so keep making these and I'll test them and tell you about my experience
Hello, can you share how you did it? I can't find any files for flashing on the postmarketos wiki page, I have TWRP installed.

I haven't tested it yet , but you'll have to use the pmbootstrap tool to build a zip that you can flash through the TWRP
The wiki of postmarketOS explains how to use the pmbootstrap tool. Go check it out

I figured it out. I created an Ubuntu VM and built it. I am not sure why but now the phone doesn't boot to pmOS, it just spits out some errors or there is only a terminal. TWRP says it can't mount /system, maybe I have to reflash the recovery.

I don't think it's a issue with the recovery and also it's normal for TWRP to not be able to mount the system
Let's try to diagnose it by going through the error
Could you upload the log and also the screenshot of the error that it spits out
Also upload the built image to some cloud service and send the link here so that i don't have to go through and build the image again
Thanks for testing it out and I'll join you soon so keep trying and I'll try to do everything i can to help you , Have a good day.

I think that it's trying to install itself to /system partition which is very small, and the "data" partition is like 50GB. Maybe it's a problem with PBRP (I can't install twrp, it doesn't work for me).
Can you try installing this file and testing if it works for you, or is it the same problem?

I'd love to test it , but currently I'm not at my home and my A7 is at home (since It's not my daily driver) but I'll test it as soon as I can get back home
Until then
Keep figuring out things
Also I think you can use the TWRP terminal to Change the size of system partition using the resize2fs command i guess
I found this when I looked into it
First to clarify, Resize Partition is different than Resize File System, TWRP provides latter option. It resizes the ext2/3/4 filesystem to the size of partition it's created on. Filesystem size can be checked with df command when mounted, and partition size with blockdev. Just like HDDs or SSDs on PC, Android's eMMC storage is divided into partitions (can be 50+). Some of them have filesystem e.g. the larger ones userdata and system. In simple cases a filesystem occupies a complete physical partition, but it's not always the case, LVM makes it possible to have single filesystem on multiple partitions. Or the opposite what happened in your case as explained here: Sometimes the zip file of: a custom ROM does not have the correct size for the system partition and if the ROM flashes a raw system image, that image will not take up the full block device. Running resize2fs can fix the size Similarly: Sometimes flashing a factory image may flash userdata with an image with a file system that does not take up the full size of the block device So TWRP can expand the filesystem to reclaim wasted space. That's what happened in your case to the /system partition. The actual size of partition was 2.5 GB, but flashed image was of 1.5 GB. Coming to your query: I realized that the system partition is too big (~1.5GB). The current ROM uses only about 40% of the partition so I want to shrink it to make space for cache and data. You want to resize partition, not filesystem. So resize2fs (which TWRP uses at back end) isn't the right choice. As your partition table suggests, you need to delete and recreate partitions 9 to 12. IT'S DANGEROUS AND NOT RECOMMENDED, you may permanently brick your device. All data on these partitions will be lost, so do backup. Also, fdisk isn't proper tool for GPT, it's for MBR partition scheme. Use parted or gdisk instead, but with great care.
So now you can just resize the system partition in case it's size is smaller than the image (not likely in my opinion)

Sorry i was sick from past 2 days so couldn't reply earlier
Anyways could you like drop to a shell when you boot up postmarketOS
If yes then check the dmesg
I also think you'll have to flash a special kernel which could also be obtained from the pmbootstrap tool
Also it'd be great if you could record a video of the phone booting up into postmarketOS as that'd help us understand until how far it can reach and where it gets stuck
Thanks alot and Take care

Hello, did you make any progress with it? I will try installing pmOS again and recording everything.
This is my installation procedure:
On a Ubuntu 20.04 VM I run:
$ pmbootstrap init
I select my device, DE, go through the setup.
Then I type:
$ pmbootstrap install --android-recovery-zip
$ pmbootstrap export
Then on the phone I unmount everything:

I recorded the installation procedure:
As you can see it boots up the first time, the file system only has 2.6GB free, when it reboots again, it just boots into busybox terminal. When trying to boot up it gives me these errors:

Sorry for the late reply
Anyways i just got home and have the smartphone I'm my hands
So i can too test it out
Also I think we should try switching to Wayland as X seems to be crashing
By using Wayland if it works we'll know that it's not a Xorg issue but if Wayland too fails we'll know that it's a big in the Kernel and the way it handles hardware
Also could you create a Telegram group for us to chat instantly I think that way we can help each other better and then we'll just create a general guide on fixing things ok XDA

I created a recovery zip using Pmbootstrap and also I set the free space parameter (after running pmbootstrap init) to 2000mb (2gb)
And then i copied that zip file from the temp directory to a Pendrive and connected the pendrive to the phone in recovery mode (PBRP Recovery) and then flashed it
I'll upload the files in a bit
Also I tried using Phosh but it just gets to the Login TTY and then doesn't boots up and i think that's because the device lacks GPU acceleration
Also here's a Telegram group link which I'll delete once you join the group
