[Q] d855 unbricking help :)

OK, I am no noob at rooting, but have drawn a blank with this one. Would very much appreciate some advice.
I have 2 x LG G3 D855s, both running Cloudy G3 ROM. Both have been successfully downgraded to Android 4.4.2 (10L), rooted with purple drake, and Cloudy Lollipop installed. Perfect.
BUT whilst doing a Titanium restore on an app, one of them rebooted this evening, and is now bricked.
- Normal boot - never does anything other than initial LG boot logo;
- TWRP takes about 5 minutes on the splash screen before reaching the main TWRP screen (but has errors, see later);
- LG download mode only shows the initial logo on the phone but the PC does not 'see' it upon cable connection, and the phone never kicks into full download mode. Connecting my other d855 fires up download mode correctly, so PC drivers are OK.
Because download mode never fully starts, I am unable to restore to stock using the kdz / LG flash.
When TWRP DOES start, it is unable to mount /data, /cache, and the log has the following errors:
E: Could not mount /data and unable to find crypto folder
E: Unable to mount /data
E: Unable to recreate /data/media folder
E: Unable to mount /cache
E: Unable to mount storage
... etc.
Within TWRP Internal Storage is shown as (0MB), and /data and /cache are not mounted. My external_sd is mounted OK.
With TWRP running, a device is seen by my PC (Google Nexus ADB Interface) but 'adb devices' shows nothing. This is the same behaviour as the phone that works, so I assume that at least is normal.
I am unable to mount /data manually, or repair within TWRP.
With /data not mounted, I am unable to proceed any further...
So my question - how do I rebuild the screwed up partitions? Or am I barking up the wrong tree?

Some more troubleshooting.
Trying to mount manually in terminal in TWRP gives me a mount unknown error 150.
Running a non-invasive e2fsck gives me:

So it looks like the whole filesystem has gone read only??? Any way to force reset it? I'd have thought dd would have worked.

[6039y] **GUIDE** Repartitioning of the internal memory

Here it is as I promised.
This phone (the model with one sim card) is sold as a device with 8GB internal memory. In fact the memory chip inside is 16GB, so we can increase the available internal space.
PLEASE READ CAREFULLY AND IF SOMETHING IS NOT CLEAR DO NOT HESITATE TO ASK.
*** The data on your device will be untouched after this operation. But again please read carefully! ***
*** A good practice is always to make a backup of everything which will be changed. I do it and I've made a backup of the entire internal memory of the device before the start of the operation which is described below. ***
*** At the end of the post there is a link to a ZIP file which can be flashed through TWRP in order to perform the procedure automatically. Also includes a check for the size of the EMMC (as there are devices on which the resizing cannot be performed...their chip is smaller).***
1. You can go to this thread and to say Thanks! @meghd00t as his static build of gdisk is used in the recovery below.
2. What is needed:
- A different TWRP Recovery with gdisk inside. It can be downloaded from here twrp-2.8.7.0-idol3-6039y-with-gdisk.img - md5sum: 66b3f82a3e2e1afe14627b3b900a9319
- (Optional) An SD card for backup of the original GPT partition layout.
- Patience and careful reading.
- The Windows users probably need the drivers from this post, for access to the device in recovery mode.
3. How to do it (the output used below is from the terminal window from which I've done this operation on my device):
- reboot to bootloader:
Code:
adb reboot-bootloader
- start the recovery
Code:
fastboot -i 0x1bbb boot twrp-2.8.7.0-idol3-6039y-with-gdisk.img
- go to the device
Code:
adb shell
- unmount all partitions of the internal memory
Code:
~ # umount /cache
~ # umount /sdcard
~ # umount /and-sec
- ensure that there are no mounted partitions from mmcblk0. The output from the mount command should looks like this:
Code:
~ # mount
rootfs on / type rootfs (rw)
tmpfs on /dev type tmpfs (rw,seclabel,nosuid,relatime,size=713016k,nr_inodes=157853,mode=755)
devpts on /dev/pts type devpts (rw,seclabel,relatime,mode=600)
proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,seclabel,relatime)
selinuxfs on /sys/fs/selinux type selinuxfs (rw,relatime)
tmpfs on /tmp type tmpfs (rw,seclabel,relatime,size=713016k,nr_inodes=157853)
adb on /dev/usb-ffs/adb type functionfs (rw,relatime)
/dev/block/mmcblk1p1 on /external_sd type vfat (rw,relatime,fmask=0000,dmask=0000,allow_utime=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
- start gdisk
Code:
~ # gdisk /dev/block/mmcblk0
all partitions can be listed by pressing 'p' but we are interested by the last two:
Code:
37 5000400 15269853 4.9 GiB FFFF userdata
38 15269854 30535646 7.3 GiB 0700 userdatabak
and their information which will be shown by pressing 'i' and entering the partition number:
Code:
Command (? for help): i
Partition number (1-38): 37
Partition GUID code: 1B81E7E6-F50D-419B-A739-2AEEF8DA3335 (Unknown)
Partition unique GUID: BDD7FA27-93D4-40BC-B266-313E074E0E87
First sector: 5000400 (at 2.4 GiB)
Last sector: 15269853 (at 7.3 GiB)
Partition size: 10269454 sectors (4.9 GiB)
Attribute flags: 0000000000000000
Partition name: 'userdata'
Command (? for help): i
Partition number (1-38): 38
Partition GUID code: EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 (Microsoft basic data)
Partition unique GUID: BD12CF41-10E7-BBF7-D096-5553B89882E7
First sector: 15269854 (at 7.3 GiB)
Last sector: 30535646 (at 14.6 GiB)
Partition size: 15265793 sectors (7.3 GiB)
Attribute flags: 0000000000000000
Partition name: 'userdatabak'
The information which is needed from the above output is Partition GUID code, First sector, Last sector and Partition name. You can write these somewhere (if your values are different from the above) from where can be pasted easily later (alternatively you can use the scrollback function of the terminal ).
- if you have an SD card make a backup of the partitions layout (in case that something goes wrong):
Code:
Command (? for help): b
Enter backup filename to save: /external_sd/gpt_partitions_table.backup
The operation has completed successfully.
- delete partitions 37 and 38:
Code:
Command (? for help): d
Partition number (1-38): 38
Command (? for help): d
Partition number (1-37): 37
- create a new partition 37, bigger in size with the same (as before) Partition GUID code, and the same (as before) start sector:
Code:
Command (? for help): n
Partition number (37-40, default 37): 37
First sector (34-30535646, default = 5000400) or {+-}size{KMGTP}: 5000400
Last sector (5000400-30535646, default = 30535646) or {+-}size{KMGTP}: 30535546
Current type is 'Linux filesystem'
Hex code or GUID (L to show codes, Enter = 8300): 1B81E7E6-F50D-419B-A739-2AEEF8DA3335
Changed type of partition to 'Unknown'
The difference here is in the last sector of the partition 30535546.
- create a new partition 38 with same Partition GUID code, but with different First sector:
Code:
Command (? for help): n
Partition number (38-40, default 38): 38
First sector (34-30535646, default = 34) or {+-}size{KMGTP}: 30535547
Information: Moved requested sector from 30535547 to 30535548 in
order to align on 2-sector boundaries.
Use 'l' on the experts' menu to adjust alignment
Last sector (30535548-30535646, default = 30535646) or {+-}size{KMGTP}: 30535646
Current type is 'Linux filesystem'
Hex code or GUID (L to show codes, Enter = 8300): EBD0A0A2-B9E5-4433-87C0-68B6B72699C7
Changed type of partition to 'Microsoft basic data'
Please note that here in the output after 'n' the default first sector is 34, so you explicitly must enter the value!!! As can be seen I've entered the next available sector (after partition 37) 305355547 but it has been corrected automatically to 30535548. So you can use directly 30535548 as a start sector. The last sector is at the end of the memory 30535646.
- write the names of the new partitions:
Code:
Command (? for help): c
Partition number (1-38): 37
Enter name: userdata
Command (? for help): c
Partition number (1-38): 38
Enter name: userdatabak
- if you list the partitions again (with 'p') the end of the table should looks like this:
Code:
37 5000400 30535546 12.2 GiB FFFF userdata
38 30535548 30535646 49.5 KiB 0700 userdatabak
- now it is safe to write the changes by pressing 'w':
Code:
Command (? for help): w
Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!
Do you want to proceed? (Y/N): Y
OK; writing new GUID partition table (GPT) to /dev/block/mmcblk0.
The operation has completed successfully.
- resize the file system:
Code:
~ # resize2fs -p /dev/block/mmcblk0p37
resize2fs 1.42.9 (28-Dec-2013)
Please run 'e2fsck -f /dev/block/mmcblk0p37' first.
... hmm ... let's run it:
Code:
~ # e2fsck -f /dev/block/mmcblk0p37
e2fsck 1.42.9 (28-Dec-2013)
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
/dev/block/mmcblk0p37: 12519/321280 files (5.8% non-contiguous), 678615/1283425 blocks
~ # resize2fs -p /dev/block/mmcblk0p37
resize2fs 1.42.9 (28-Dec-2013)
Please run 'e2fsck -f /dev/block/mmcblk0p37' first.
... well the resize2fs have some checks and refuses to resize the file system therefore we must force the execution:
Code:
~ # resize2fs -fp /dev/block/mmcblk0p37
resize2fs 1.42.9 (28-Dec-2013)
Resizing the filesystem on /dev/block/mmcblk0p37 to 3191893 (4k) blocks.
The filesystem on /dev/block/mmcblk0p37 is now 3191893 blocks long.
The device now can be rebooted and its internal memory will be almost 12GB which compared to its previous size is a very nice upgrade. Screenshots before and after the repartitioning can be seen here.
Update (19.09.2015): This is a link to a flashabable zip which can be used from the TWRP to automate the process. Can be used with any TWRP recovery for 6039.

Just tried it, and it worked like a charm. Thank you very much!

Wow ! Kudos to meghd00t and petrov.0. I just ordered this phone as a backup, waiting for my beloved Xperia Z1 Compact to be saved from watering (medium rain during less than 10min, so long Sony waterproof phones...). Can't wait to receive it and play with this extra storage !! Thank you :victory:

Here i'am, crazy thinking that if the 6039y(Single chip, SDcard and 8Gb) come with 8Gb worth of wasted money, that the 6039j dual chip and 16Gb non-SDCard version may very well come with a SDCard reader hardware worth of wasted money.
It would be like just changing the Chip Support slot thing or whatever...
Can someone support my craziness and post a picture of thi "where the chip stays" of the SDCard reader version of this phone??
Thanks a lot!!

Well ... I like crazy things. But is impossible just to add a chip.

Maybe someone can post the list for 16Gb dual sim variant?

Ok, I bit the bullet and resized the "userdata" partition. Only that I did not create the smaller #38 partition, I did not see any reason to do it (if any update tries to store something inside it, will fail anyway; this partition does not look special, all *bak partitions have the same GUID). Plus there isn't any "userdatabak" partition on 16Gb models. Instead I made partition #37 up to the latest available sector (30535646). The phone is working just fine.

OK. But don't be fulled by the GUID. Most of the bak partitions contain data which is equivalent to the data in the primary ones (aboot, rpm, sbl1 etc.). The data is patched in both partitions with the same patch during an upgrade.

Script to repartition "internal memory"
Hello petrov.0, all
Is it possible to create a shell for all thoses commands ?
In this case if partitions are lost (upgrade, patchs....) we could apply it easily.
And nice discovered.

No it is not:
Code:
GPT fdisk (aka gdisk) is a text-mode menu-driven program for creation and manipulation of partition tables.

Hi petrov.0 great news and thanks.
Just a doubt, a friend of mine will receive Idol 3 4,7" 8 GB tomorrow, he can made OTA update (that I think are available for security reasons as "stagefright" and another I know Alcatel get users a way to set SD as main memory) and then use your guide to expand memory t 16 Gb or for this operation is better been in a fresh unchained device not updated?
Because in this second option device become 16 Gb Rom but will be afected by stagefright and for the rest of his life
Thanks!

It shouldn't be updated. The official updates for 6039 removes the fastboot commands therefore you will not be able to do the repartitioning nor to root the device. Give me the update file and will modify it in a way which will preserve the commands (there is a risk for a broken device after it though ... I wish to try such modification first on my phone, but unfortunately I still do not have official update for it with which to test).

By the way is there any hope (other than getting Alcatel to push an update to put fastboot commands back in, cause is anyone that optimistic?) for people who have indeed updated to recover those?

If you find a way to root the device after the update then may be there is a hope.

Understood the problem is new update that remove some action from fastboot needed for repartioning. Idol 3 was received and he resize rom from 8 to 16 with no issue with your guide, after that he made OTA update and they are working perfectly, no issue with the new partitioning size and device is working well.

Not some but all fastboot commands are removed. Glad to see that you have made it though. The OTA update however is a mistake. Now you can't get root access nor the fastboot commands are available.

Yes, it was risky but probably he is not interested in root, I only inform you that new partitioning with OTA is still there, I think is a goodnews and a base to start, now the perfect situation is if Alcatel made a future OTA as soon as possible with fastboot perfectly working.

There is nothing wrong with the fastboot commands prior the update. I have doubts that they will be returned. Thanks for the info though (despite that I already know this by looking in the update files). I can't live without root access however therefore there is no option to loose it.

I'm kinda confused here. Are all the steps done from a terminal on the computer or is some of that to be typed inside the TWRP terminal? Because as soon as I boot TWRP with gdisk I get a device not found from typing adb shell. I'm pretty sure I have all the drivers mentioned in the linked post (and even more too). Any kind soul to explain how stupid I am being (because I know that's the solution in the end, I'm a fool)

Everything after adb shell must be done directly on the device. The VID & PID of the device are different in the recovery and you don't have the necessary drivers. Try to install the drivers mentioned in the first post (- The Windows users probably need the drivers from this post, for access to the device in recovery mode).

GUIDE: How to repartition for vendor and how to use GSIs

Guide to repartition your LG V30 to have a vendor partition
This guide is for people who are willing to repartition their V30 (Tested so far on my H930).
It will make your system partition smaller by 512MB, and create a vendor partition instead.
You will still have enough space for (full) stock ROMs too (they just ignore the new partition then)
Code:
#include "std_disclaimer.h"
/*
* Your warranty is now void.
*
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
*/
What you need:
The scripts attached in the zip file
TWRP
A PC with working ADB (I doubt you wanna write everything in the TWRP command line)
Oreo firmware recommended (for LOS and GSIs)
Bravery
(should be quite safe though, as I did it myself, and know other people who did it)
Steps
Read this carefully before you execute it, twice! Make sure you understand every step. Learn it to the point of when i wake you up in the middle of the night, and ask you questions about it, you can answer instantly.
Boot into TWRP!!!
Make a backup of EVERYTHING on your phone (system, boot, recovery, data and so on)
Code:
The script will format system again, its important to backup!
Copy the contents of the .zip file to your phone
Open a command line/terminal on your PC (wherever you have access to ADB)
Connect your Phone to your PC
Everything now in command line/terminal
adb shell
cd /path/to/the/script/folder
Code:
e.g.
cd /external_sd/repartition/
./backup_gpt.sh
Code:
This will create a backup of your current gpt table on /external_sd/GPT_orig.bin
Code:
Todo this manually execute:
sgdisk /dev/block/sda --b=/path/to/GPT_orig.bin
./make_vendor.sh
Code:
Follow instructions on screen if you really wanna do this!
To apply the changes, remove the --pretend from the sgdisk commands! Otherwise it will just pretend to apply the changes (so you can check if it would fail or not)
(not an automatic script incase something goes wrong)
Reboot into recovery again
Restore your previous backup
How to revert the changes?
Do everything till step 7
./restore_gpt.sh
Code:
This will take the backup of your gpt table on /external_sd/GPT_orig.bin
Code:
Todo this manually execute:
sgdisk --load-backup=/path/to/GPT_orig.bin /dev/block/sda
Wipe system again
Flash a .kdz (Instructions case be found on XDA)
How to use a GSI (Generic System Image)
Make a backup of EVERYTHING on your phone (system, boot, recovery, data and so on)
Flash treble enabled lineage build: link
Wipe data (if it isnt)
Reboot into bootloader
in commandline/terminal:
fastboot flash system <name_of_gsi>.img
OPTIONAL:
fastboot boot <twrp>.img
Code:
fastboot doesnt provide a way to reboot to recovery directly, you can also optionally do the button dance
flash magisk/gapps
fastboot reboot
Thanks for the original script from here

what happens if it is partitioned and we flash a kdz using lg up (without reverting the partitions)?

I believe that it just changes the gpt to its original state, so if everything goes right, nothing will happen except you losing the vendor partition

Will this allow my US998 to be supported by the treble project?

Yep, it should do that. The kdz rewrites your GPT, atleast it should. Doesnt contain that for nothing i suppose?

It should work also on your US998 to create a new partition. The treblelized ROM isnt yet built for the US998 though. Dont have any testers that could have tried it out on the US998.

so if i make the changes i can safely flash a kdz and revert everything back to stock?

Or, less hassle, you restore the GPT that you should backup before anyway (see guide) ^^
That also works.

do you own a h930(64gb) or h930g(128gb)?

I own a H930

ah ok, so this happen on 64gb version too

Hmm...
Ok, forgot to add a message to the script ?
you have to remove the --pretend from the commands, otherwise it will just do like it does it, without actually doing it (to see if everything will work the way it should before actually applying the changes)
sorry about that

Glad it worked. And ehhm, i dont think its normal that TWRP sees it for backups? But if it does, no need for a new TWRP (tbh, during all my testings, i didnt check this, or didnt look if vendor is there or not)

i've made several test on it...wiping system data cache & art, reflash your recovery,format system in recovery & via adb..
The only thoing i haven't tested is to flash full kdz and then repartition.
i don't know if this can be useful for debugging,but when i've switched to oreo i don't flash full kdz, but the twrp flashable rom found on v30 section of xda

Hm... that shouldnt matter actually. Its a weird behaviour though you have there. Can you "tick" system in the mount options of TWRP? if no, send me a log of that too. This seems really weird to me.

[GUIDE] [DANGEROUS] Resize system partition

WARNING​
Code:
This process is extremely dangerous. You may brick your device.
Do it only if you know what you are doing!
I am not responsible of bricked devices or dead sdcards.
Hello guys,
I've decided to write this guide since this seems to be the only way to resize system partition to install larger GSIs.
Before starting remember to always make a backup since you will loose all your data.
Also DO NOT DO a simple copy-paste compare with yours first and if you have any doubts write in the comments before enter the doubtful command. Prevention is better than cure!!
This process has been tested on my own device but it has not been tested restoring stock firmware.
(You can also join the telegram group to ask for help https://t.me/MotorolaOneAction)
Requirements​
Latest TWRP downloaded (to be booted through fastboot later)
Parted arm64 static binary (attached below)
Latest fastboot and ADB commands installed
Patience

Boot to TWRP from fastboot
Run the following commands:
Code:
adb push /path/to/parted /sbin/parted
adb shell
chmod 777 /sbin/parted
parted /dev/block/sda
p free
Now parted will list your partition table which should be like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Save the output of the command above (this is very important to restore original partition table if you will run into issues in the next parts)
Now with extreme attention type
Code:
rm partition_number
replacing partition_number with the number of the partition following the reverse order until you reach system_b partition removing it too . In my case I'll type:
Code:
rm 42
rm 41
rm 40
rm 39
Once you removed these partition it's time to recreate them following the original order but increasing the target partition size, in our case system_b. Type
Code:
mkpart name fs_type start end
replacing name with the original partition name (refer to the command output you saved at point 5), fs_type with original file system type, start with the end value in MB of the previous partition, and end with start + size, where size will be the size of the target partition (size is the original size of the partition except for system_b which I've decided to change to 4221MB, 1000MB larger than original one). If it says that the partition isn't aligned, type Ignore. In my case I'll type:
Code:
mkpart system_b ext4 5630MB 9851MB
mkpart oem_a ext2 9851MB 9918.1MB
mkpart oem_b ext2 9918.1MB 9985.3MB
mkpart userdata ext4 9985.3MB 128GB
Now restore the partition flags typing
Code:
set partition_number msftdata on
replacing partition_number with the number of the partition. In my case I'll type:
Code:
set 39 msftdata on
set 40 msftdata on
set 41 msftdata on
set 42 msftdata on
Now type again
Code:
p free
and compare the output with the original table saved before, they should be quite identical.
Type:
Code:
quit
exit
Reboot to bootloader and boot again into TWRP
If in the logs you see lot of red lines saying it could not mount oem partition and userdata partition don't panic, it is normal since they have not been formatted yet (they are registered into fstab with a different file system type). Type:
Code:
adb shell
mkfs.fs_type /dev/block/sdapartition_number
replacing fs_type with original file system type, partition_number with the number of the partition. In my case I'll type:
Code:
adb shell
mkfs.ext4 /dev/block/sda39
mkfs.ext2 /dev/block/sda40
mkfs.ext2 /dev/block/sda41
mkfs.f2fs /dev/block/sda42
Now reboot to bootloader and again into TWRP. Logs now should be free of red lines and you should be able to mount all partitions again.
You have done it!! Now you are able to flash larger GSI (I suggest you doing it from TWRP since fastboot may have some problem recognizing the resized partition size, also remember to change the active slot to the resized one, in my case the slot b)

Reserved

Why this?
GSI running like Havoc, Dotos...
Is this for running Android 12?

Vanilla GSIs will work without this. But larger GSIs that include Gapps will not because they are larger than system partition (like Pixel Experience, dotOS with Gapps, etc.). You can still flash vanilla build and Gapps zip of course to avoid doing this.
Regarding Android 12 I have not tried it yet.

please someone port postmarketos to this device, kane has a lot of potential
edit: i'm talking about pmos, because this resizing process has sense only for postmarket, if any other roms are bigger than system part, than they are just bloated worthless ****s.

sorry to bother you.
i found your post after long time of searching. I'm noob for installing GSI,to do so i need to resize system partition.but i have zero idea about resizing and also seems like its very critical,and if i made any mistake to resizing it i may have to lost my phone forever.
I'm here to make a request to you that if you help me out to resize partition by a easiest way .i hope you won't reject me. I'm really fed up about resizing.here is my device details
phone: mi 8 pro
codename: equuleus
Rom : 128 GB
Default system partition size : 2.74GB
Hope you will help me

Yep, but partitions like /system /vendor /system_ext and product do not appear, is it because of super partition?

Some phones also need system_a resized. I couldn't install a bigger GSI on One Action/troika and resizing system_a fixed it.

as partições ( parted /dev/block/mmcblk0 )e (parted /dev/block/sda) não contém partições, mas as

Hello, I need to increase the partition for GSI. Could you please help me? Which section should I enlarge and what commands should I enter? (I tried to do everything according to the instructions, but I had questions and nothing happened)
1. I put the file (parted) in the root of the disk (C) and wrote (adb push C:/parted /sbin/ parted) is that correct?
2. What should I enter in (fs_type), (msftdata) if I have spaces here?
3. After the second input (p free), I lost the names of the modified sections.
4. The red lines in TWRP did not disappear anywhere and I could not boot into the system.

Were you able to figure out how to expand the system partition with a super partition?

For fastboot to take the partition names use the following parted command:
Code:
name <partition-number> <partition-name>
On some devices this helps a lot, consider adding it to the main thread ^^

Some devices also use /dev/block/mmcblk0 instead of /dev/block/sda

Hi, how can i add partition like product and vbmeta, tried to add using "mkpart PRODUCT ext4 start end" then "mkpart VBMETA space start end" it added but cant flash using twrp, tried on fastboot "Fastboot flash product product.img" then same with vbmeta. but nothing works, zip files cant mount those. Please help

How To Guide Resize internal storage on Xiaomi Pad 5 (nabu) and install PostmarketOS Preview

Please carefully read all steps twice and be sure you understand them, the last part explains why you may want to have some free/unused space in the end.
0. Your device should be unlocked with Xiaomi
1. Developer options should be enabled
2. Check your MIUI version and download a stock image to have at hand all the original images in case you may need them.
For example is easy to forget to switch the slot a/b and write the wrong slot and break your device boot to android.
3. Reboot to OrangeFOX
- Download OrangeFOX image, please read this thread [UNOFFICIAL] Xiaomi Pad 5 nabu OrangeFox/TWRP recovery
- adb reboot bootloader
- fastboot boot xiaomi-nabu-orangefox.img
- adb shell
- review your partitions: ls -la /dev/block/bootdevice/by-name/
- we are interested in userdata partition location, in the below output we can see that is on /dev/block/sda device and it is the 31th partition on that device.
Code:
sh-5.0# ls -l /dev/block/bootdevice/by-name/ | grep userdata
lrwxrwxrwx 1 root root 16 1970-04-30 14:11 userdata -> /dev/block/sda31
4. Use parted against the /dev/block/sda device and print some info about partitions
Code:
sh-5.0# parted /dev/block/sda
GNU Parted 3.3
Using /dev/block/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.

6. Note the end of the last partition in the above list, 10.9GB, this number will be used as the start of the new userdata partition, followed by the end of the partition.
Let say that we want to make an approx 40GB userdata partititon using the following command:
NOTE, between userdata and 10.9GB are 3 spaces, one of them replace the partition type flag, it is important to use 3 spaces at this step.
Code:
(parted) mkpart userdata 10.9GB 50GB
7. Use print described at step 5 and see the result
Code:
(parted) print
Then exit/quit parted
Code:
(parted) quit
8. Reboot to Android and let the OS do the job fixing and formatting the userdata on the new size, will take a while to boot first time after resize, so grab a coffee, a beer, or else, note, it is important to keep the original partition name "userdata"
Code:
sh-5.0# reboot
9. Reboot to OrangeFOX again as described at step 3 and now create the PostmarketOS partition, I will name the partition as pmos:
print the actual partitions
Code:
(parted) print
Number Start End Size File system Name Flags
.....
31 10.9GB 50.0GB 39.1GB userdata
Use the last end as the start of the new partition and for end the desired extra size for your partition, let pretend we want a 20GB pmos partition as ext4 (minimum partition size is 4GB)
Code:
(parted) mkpart pmos ext4 50.0GB 70GB
The remaining free space, if any, can be used for future OSes, let say you want to have Windows and/or Ubuntu along your Android and PostmarketOS in the near future, think twice and partition wise your device and keep some free space if you think you will need it.
After each command you can check the free/available space with following command
Code:
(parted) print free
10. At this point your Android should be running well with the new userdata partition and you are ready to install the PostmarketOS nabu preview.
- Download preview images, please read this thread [INFO] PostmarketOS Linux boot on Xiaomi Pad 5 (nabu)
(NOTE THE IMAGES ARE NOT YET AVAILABLE I WILL UPDATE THE ABOVE POST IN THE NEXT FEW DAYS WHEN I AM DONE WITH THEM)
- Reboot to fastboot and check from which slot is your android booted
Code:
:~$ fastboot getvar current-slot
current-slot: a
finished. total time: 0.005s
Keep in mind that your current version of Android use slot A in above case, slot B is temporarily unused and we can take advantage to install our boot loader. Please note, if you update your Android version the new version will use the unused slot to install updates and our images will be lost, i am talking about 3 partitions involved to properly boot PostmarketOS, boot, vbmeta and dtbo partitions.
In order to flash and boot PostmarketOS you should change the active slot, because above the Android slot was A i am changing the slot to B
Code:
:~$ fastboot set_active b
Setting current slot to 'b'...
OKAY [ 0.046s]
finished. total time: 0.046s
11. Write PostmarketOS preview images.
Flash the new vbmeta with disabled verified boot, more info in PostmarketOS Wiki at Android_Verified_Boot_(AVB)
Code:
:~$ fastboot flash vbmeta_b vbmeta_disabled.img
Erase Android DTBO partition, we do not need it, but if present will be loaded and will prevent our boot
Code:
:~$ fastboot erase dtbo_b
Flash PostmarketOS boot.img
Code:
:~$ fastboot flash boot_b boot.img
Flash PostmarketOS image, please use the partition name you created for PostmarketOS at step 9, this process will takew a while, grab another beer
Code:
:~$ fastboot flash pmos xiaomi-nabu.img
Now you are ready to boot your PostmarketOS preview
Code:
:~$ fastboot reboot
You can switch from PostmarketOS to Android via changing active slots with fastboot, out there are some android/linux apps that can change the active slot while rebooting, you may need to search for them and test if they work.
The last step is to use the free space somehow, by creating one or more new partitions, in order to be able to do that you need to alter the GPT size limit, by default the limit is 32 and if you try to add a new partition you will get a similar error as the following one
Code:
(parted) mkpart WIN ntfs 50.5GB 126GB
mkpart WIN ntfs 50.5GB 126GB
Error: Too many primary partitions.
If you are on slot B to use PostmarketOS you need to switch to slot A to boot my OrangeFOX again:
Code:
:~$ fastboot set_active a
:~$ fastboot boot xiaomi-nabu-orangefox.img
To overcome the limit you will need to use the sgdisk tool, the following command should do the job:
Code:
sh-5.0# sgdisk -S 54 /dev/block/sda
Adjusting GPT size from 54 to 64 to fill the sector
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot or after you
run partprobe(8) or kpartx(8)
The operation has completed successfully.
sh-5.0#
Now you can use parted to create new partitions, up to 64.
Enjoy
Thanks @Vagelis1608 for reminding me to add the last part about increasing the GPT limit.
P.S.
This thread is about how to repartition your device and install PostmarketOS preview images, if you want to discuss about my PostmarketOS please use this thread [INFO] PostmarketOS Linux boot on Xiaomi Pad 5 (nabu)

I would recommend to mount the "extra space" that's left until you need it for something else.
Either for something non vital ( cache/dalvik-cache ? ) or, better yet, simple storage.
I will look into mounting it as a "virtual SD card".
But yeah, this is exciting and I can't wait for you to release the images.

Indeed, this is a way to use it, but there cannot be added a new partition without some extra work to alter the GPT itself and increase the limit of 32 partitions.... an operation that require a few extra steps.

Oh, yeah, I forgot about that.
But still, that will have to be done for a 3rd OS, as you mentioned
Though the user won't have to wipe their data again, which is good

Oh, yeah, I forgot about that.
But still, that will have to be done for a 3rd OS, as you mentioned

If the space is left unused/free as suggested there is actually an easy step to alter the GPT later and add one or more partitions without losing anything. I just omitted the step as i thought is not related to the scope of this HowTo.
My OrangeFOX image contains a proper version of sgdisk that is able to alter the GPT size.
Actually i think i can add the extra steps at the end of the post #1 indeed, thanks for suggestion.

I find that it's better to do all the work at once.
Helps to not forget something important.
Good thing your sgdisk is ready and it doesn't need any extra tools.
Optional steps, for sure, but still good to have.
Just don't go over 8192 partitions. Things seem to be bugged after that, from what I read.

I have added the last missing steps, thanks.

It's fine, don't worry about it.
It's not like ordinary users will follow it. It's for advanced users

Did anyone do it? Do you have Some screenshots or video review?

I did it on my nabu, i do not have any screenshots or videos, but i have doubts that will help more than what is in the first post, if you have any doubts do not do it, read more, study more, ask questions before do anything, this way you will avoid a soft brick.

I've tried to follow your steps for partitioning, and the pmos guide of porting a new device. I used the map220v kernel, and using pmbootstrap i build and solved some configs error. After i've extracted boot.img and xiaomi-nabu.img, flashed vbmeta_disabled, and then the other images. But when i try boot the slot b, it will redirect to fastboot. How can i solve it?

DTBO? You need to erase dtbo on the slot you are using pmos with.

Also you need to disable AVB in vbmeta too and be sure you have the Postmarketos on the right slot.

Yes i did what you all said before flashing on boot_b and pmos, but maybe i'm doing that wrong.
I erased dtbo_b like this guide, and i've generated the disabled vbmeta with
Bash:
avbtool make_vbmeta_image --flags 2 --padding_size 4096 --output vbmeta_disabled.img
and flashed this image on vbmeta_b

Then this HowTo guide reached his scope, you had successfully resized your internal storage, why your OS does not boot is out of scope of this thread, you may need to seek assistance from the developer of your packages. At first glance i can say that your kernel is not properly configured and your DTB is not complete, but please ask the developer of your sources to debug his work and maybe to help you with your issues. Or watch my other threads about PostmarketOS on nabu as soon I will make my sources available as well as some prebuild images.

The preview images of my PostmarketOS port for nabe are available now, check post this thread [INFO] PostmarketOS Linux boot on Xiaomi Pad 5 (nabu)
