Need help for the repartitioning of Z3 in order to install Windows 11 - Moto Z3 Play Guides, News, & Discussion

Recently I noticed that Windows 11 Arm64 version is possible to run on Z2 Force which has the same processor (Snapdragon 835) with my Z3 retcn version, so I feel very like to give it a try on my Z3. (Project Renegade)
Unfortunately I am stuck at the first step which is repartitioning the internal storage.
According to the guidelines, I will need to:
1. Repartition device;
2. Format new partitions;
3. Mount PE partition as /mnt;
4. (And other following steps);
The example given by the project's guidelines is OnePlus 6T 128GB, which apparently has its /userdata on /dev/block/sda, and its /dev/block/sda seems has only 17 partitions in place originally.
I see on my Z3 its /userdata is on /dev/block/sdb, which has already 21 partitions existing, and also it has so many disks existing as in below:

mkpart win ntfs 3000MB 100GB #97GB
mkpart userdata ext4 100GB 116GB #16GB
The problem is after I removed partition 21 on /dev/block/sdb (115.9158GB) and created the esp partition without problem, then I needed to create the pe partition but I got an error as:
(parted) mkpart pe fat32 500MB 3000MB
Error: Too many primary partitions.
I understand the number of primary partitions can not exceed 21, but in this case how can I continue to create the partitions needed for the Windows 11?
I think I may need to shrink the size of /dev/block/sdb, keeping the /userdata partition still on this disk but taking size only 16GB and then utilize the free space to create a new disk /dev/block/sdg to hold esp, pe, win partitions but I don't know how to do it. The Z3 currently is not my daily use, so that I have no problem losing all data on it.
Could you please help and see how can I progress on this problem?
Grateful to your help!

Android (Samsung) partitions list

I think this thread is obsolete now, please go to
[DEV][REF] El Grande Partition Table Reference
instead, which contains more facts
Hi,
I want to create a list of Android partitions, to collect information for different purposes.
My current cause of investigation is about repartitioning emmc bricked Samsung phones, but the guide could collect all kinds of information (in short form, eventually with links to deeper investigations).
I want to format this as a living post, with new information added where appropriate (I assume the wiki would fit better, but I don't see a section to put this, also I don't know if fitting to Samsung only or Android in general until enough information is collected).
So let's start:
So let's visit partitions one by one:
GANG
* has zero size in PIT, seems to be hidden in the following unused area
* no real partition, but included in PITs
BOOT
* has zero size in PIT, seems to be hidden in the following unused area
EFS
* mounted on /efs
* contains many personalized information
* IMEI
* bluetooth MAC etc.
* restoration only possible with JTAG
* should be backuped!!!
SBL1, SBL2
* BL = boot loader
* S = Secondary?
* why do we have SBL1 *and* SBL2?
PARAM
* currently I don't know anything about this
KERNEL
* contains kernel (obviously)
* also contains recovery on some/many Samsung Galaxy phones (e.g. N7000)
* read only
RECOVERY
* seems to be unused on Samsung Galaxy N7000, KERNEL comes with recovery integrated
* read only
CACHE
* mounted on /cache
* temporary data
* can be cleared without loosing any important data
MODEM
* modem software for cell phone
* can be flashed from stock file
* read only?
FACTORYFS, system
* mounted on /system
* main OS code
* system apps
* read only
DATAFS, data
* mounted on /data
* user apps
* read/write
UMS, userdata
* mounted on /sdcard, sometimes /emmc
* sometimes called internal sd
HIDDEN, PRELOAD
* mounted on /preload
* purpose?
FOTA
* F = Factory?
* OTA = Over The Air
* may be used for Updates by stock ROM
Here are also some general thoughts about repartitioning these partitions to be mixed into the list later if it fits (just as a reminder):
* if you have a brick in a partition you cannot create a backup to restore afterwards
* partitions which have stock contents (not personalized) will be easy
* EFS cannot be restored without having a backup,
it contains nearly all really personalized information, with the most important data being the IMEI, which is unique to your phone. You find it printed on a sticker on your phone, but currently no one seems to be able to patch it into a generic copy of the EFS.
* some partitions will be needed to boot into recovery and/or download mode
I would assume BOOT, SBL1 and/or SBL2 are involved.
Some may be needed to boot into both recovery *and* download mode.
Some may be needed only for one of them.
If a PIT would move these, you cannot enter download and/or recovery again, thus your phone is nearly dead and only recoverable by JTAG.
* what about PARAM?
First of all, great initiative!
I have a SE Xperia Arc and the file structure differs a lot from your Samsung device.
Here is a list of the partitions, their current mount point(s) and filetype. I have put some useful references to the list. This will probably provide more accurate descriptions, rather than giving a brief explanation on each file system.
rootfs / rootfs [1]
tmpfs /dev tmpfs [2]
tmpfs /mnt/asec tmpfs
tmpfs /mnt/obb tmpfs
tmpfs /mnt/sdcard/.android_secure tmpfs
devpts /dev/pts devpts [3]
proc /proc proc [4]
sysfs /sys sysfs [5]
/dev/block/mtdblock0 /system yaffs2 [6][8]
/dev/block/mtdblock1 /cache yaffs2
/dev/block/mtdblock2 /system/vendor yaffs2
/dev/block/mtdblock3 /data yaffs2
/dev/block/vold/179:1 /mnt/sdcard vfat [7][9]
/dev/block/vold/179:1 /mnt/secure/asec vfat
References:

I also found two more links that could be useful in this thread.

Thanks, nice contribution.
Can you provide a dump of 'parted print' for your device?
Unfortunately, the parted partition command is not included among the Xperia Arc's stock binaries, nor in BusyBox 1.20.2 (but hopefully in the future).
Do you have a pre-compiled binary to share?
Here is what I can contribute to your collection for now:
Code:
[email protected]:/ # busybox fdisk -l
Linux localhost 2.6.32.9-perf #1 PREEMPT Wed Jul 4 12:32:24 2012 armv7l GNU/Linux
[email protected]:/ # busybox fdisk -l
Note: sector size is 4096 (not 512)
Disk [URL="http://shmilyxbq-compcache.googlecode.com/hg/README"]/dev/zram0[/URL]: 62 MB, 62914560 bytes
255 heads, 63 sectors/track, 0 cylinders
Units = cylinders of 16065 * 4096 = 65802240 bytes

you can try the attachment to this post
but I'm not sure if an exynos processor (Samsung Galaxy Note N7000) has the same executable format than your phone, at least both have armv7l.

The parted binary worked fine, but the file system on the LT15i needs to be explored some day.

why? Do you mean mtdblock0-3 are really located on zram0?
Or what else?
mtdblock0-3 don't seem to be partitions of a block device, like mmcblk0p1 is a partition on mmcblk0

Sorry for my ambiguousness...
After having a bad nights' sleep, I made some re-thinking.
I dd'ed the /dev/zram0 (62 914 560 bytes). This value also corresponds to the content found in /sys/block/zram0/disksize and I find it unlikely that the OS keeps the entire amount of mtdblocks within this memory constraint, even if they are compressed. I have not tried to mount the zram-image on a Linux system, so I cannot tell anything about its content. My belief is that this image carries some RAM contents and perhaps some cache information.
Did you find anything similar in your Samsung device?
The mmcblk:s seem to represent the MicroSD-card device and I assume the mmcblk0p1 is the (only) partition.

The ram* may be what is zram in your device.
The 'z' may indeed mean compression.
There are several tmpfs in our device (e.g. /tmp and /dev, perhaps they use these ram disks).
Also the root file system where everything is mounted runs in ram.
The zram0 seems to act like some kind of swap RAM and was obviously added to the latest SE 2011 firmware version [1].
My guess is that Sony Ericsson decided to pick the compressed alternative, due to the smaller flash memory in their Xperia 2011 devices. This solution probably costs some clock cycles, but I assume it gains in overall internal storage capacity.
I found an interesting thread where sirkay showed how to initiate/alter the zram size.

You guys are confusing.
The Xperia NAND disk device is translated to an MTD block device in the Linux world. The partition boundaries are hardcoded in the bootloader passed to the kernel via the ATAGs parameters. You can see those partitions via /proc/mtd
Code:
# cat /proc/mtd
dev: size erasesize name
mtd0: 19000000 00040000 "system"
mtd1: 00600000 00040000 "appslog"
mtd2: 06580000 00040000 "cache"
mtd3: 1a400000 00040000 "userdata"
Still those are only the partitions the bootlooader chooses to expose to the kernel. In reality, there are more, unknown to the kernel.

I'd say this is the way it's most commonly done in Android devices, using a raw NAND device with the MTD translation layer. It's far more uncommon using block devices, such as MMC devices as the primary internal memory.

Thanks for this. :good:
I am still curious about the possibility to gain boot or root partition access in Xperia?
Many other devices come with this feature, e.g. HTC Incredible S, HTC Vision, Acer Liquid Metal and on the widely spread article HOWTO: Unpack, Edit, and Re-Pack Boot Images).
Oh, by the way...
I found a collection with recovery images on OnlineNandroid.

In Xperia, the boot partition is not visible to the Linux kernel, so you can't simply dd it to an image file. The easiest way is running Sony Update Service reflashing your phone with the current firmware, and then copy the temporary files it downloaded, recreating the FTF file using Flashtool. Unzip the FTF and you've got the boot.img. Now split it, do whatever you want to change and flash it using fastboot. There's a YouTube video showing this in detail. Search for it. Or download the firmware FTF directly from a trusted source.
I looked in fota0.sin and found a few more partition names on the Xperia (Active):
Code:
amss
amss_fs
fota0
fota1
dsp1
boot
system
userdata
cache
image_backup
amss_log
vendor
ramdump
Thanks a lot for this, a really valuable post!
I know I wont find the help I need to do what I want here, but ill provide the stuff from my Galaxy Note tomorrow (partition layout/vold)...
My Galaxy Note is nice, but 2GB is a joke for apps, and damnit I want my sdcard to actually be mounted as /sdcard! (PITA for apps that utilize /sdcard for game data and backups, not to mention having a 32GB or 64GB makes the joke 10GB internal... a JOKE!)

From the above list is it possible to know the boot paritions.
on S2_lte_I9210 /proc/partitions list the system partition as /dev/block/mmcblk0p24 /system but not the boot partition.
I'm eagerly waiting to do boot.img backup using via dd command

partition list on samsung galaxy S2_lte I9210

[Q] where is ramdisk.img ?

hi, all!
Modify /init.rc configure file is my plan, in android(linux) box, /(rootfs) locate RAM.
So, modify ramdisk.img(initrd.img) is aim, However, I find any image file except recovery backup image:
[email protected]:/ # /system/xbin/busybox find / -name '*.img'
/mnt/sdcard2/clockworkmod/backup/2012-01-01.00.03.03/boot.img
/mnt/sdcard2/clockworkmod/backup/2012-01-01.00.03.03/recovery.img
/system/etc/firmware/modem.img
Did the partition that ramdisk.img save in not mount by kernel ?

Ramdisk is inside boot.img, you must use dsixda's kitchen to decompile it.
Sent from my PC36100 using xda app-developers app
Yes, the ramdisk is inside the boot.img. The recovery.img contains its own ramdisk. The partition is a basic format created just for android. The first 0x30ish bytes contain offsets and sizes for the kernel image, ramdisk, kernel command line, and stuff like that. And no, the ramdisk is not compiled; you do no decompile it. It is compressed. You can pull the ramdisk out of the partition and decompress it using standard commandline tools.

You can believe what you want but do you really think I would post wrong info?
There are also other strange partitions like the Qualcomm MDM efs sh1ts. Seems them make some things common between models.

i9502 uses Qualcomm modem for second CDMA SIM-card, so no wonder if there are partitions for Qualcomm MDM.
May be I9500 uses the same PIT as I9502, or may be somehow you've got wrong PIT.
At least I9505 uses different PIT according to your post.
Hi, Odia. Thank you for info.
What do you think - what CDMA partition is doing in this PIT for 9500? Maybe they made the identical partition table for all models 9XXX and it's just emty here? At least it's not mounted. Because no one model except for I9502 has second CDMA module. 9500 - no LTE, GT-I9505 with LTE and a Korean variant with LTE (SVH-E300S).

Sorry for the late reply, I did not notice your post.
I am really not sure what Samsung think here, since the I9502 PIT has an extra 2 partitions for the second radio and it's EFS, when I get some free time, I will post full details on the i9502, i9505 and i9508.

Maybe I'm wrong, but if you take boot.img 0p9
In OP: 0x200 x 0x4000 = 800 000 in HEX, Size comes to: 8 388 608 bytes in DEC. It's ok.
In my post: #blocks = 8192 = 0x2000.
As you write block size is 0x200 = 512 in DEC. So, my size = 512 x 8192 = 4 194 304 bytes. Why?
It would be equal with block size 0x400.

Thats because physical to virtual mapping, my OP is physical from FlashIC and how the bootloader see's it, you should not mix the two or you will have strange results

Of course I used the OP data. Now everything is clear for me. Thanks. P.S. Would you attach your PIT(9500) file, please.
Odia said:
The structure of the PIT is defined below:-
Dear Odia. Is it possible to attach a valid pit file in this post? I have a S4 i9500 that has a soft brick. I can access it from ODIN and ADB, but I cant mount anything there.
The phone stucks on logo and I think the partition are corrupted, because this problems happen after I'm trying to unmount the internal sdcard (a message appeared for me, when I'm trying to change the vold.fstab files). During process of unmount, the phone froze and I restarted it. After this, the phone doesn pass of the Samsung logo and goes to recovery mode, with a various messages about impossible to mount the directories.
Because of this, I think the only way is to flash a new pit to rebuild the partition. Is this correct?
I really appreciate your help, if possible!
Tks a lot!!!

How did you go about reading and generating this? (The hidden-by-kernel mmcblk0boot0 / 1.)
@Odia: now with new firmware MGG (brand vodafone Italy, only for I9505) is impossibile to go back to a previous firmware from this new one, i think sammy update bootloader. I found this your useful thread here
[Util] Sboot Checker, is possible in your opinion to do something similar for this new situation on I9505? Must first extract old bootloader from pit file right?
Sorry if i go little OT here, if you want to write me in pm.
Thanks, regards
I'm trying to extract pit from my S4,
but I can't be sure about command.
dd if=/dev/block/mmcblk0 of=/sdcard/out.pit bs=8 count=481 skip=2176
is that correct? my S4 is 32GB.

Please check i9500
Can someone please check this I think my partitions are not right this is on 4.3, I cannot adb push to system anymore

[Android 11][OxygenOS] What is the new 'mmcblk0'?

The device is OnePlus 8 Pro, it is completely functional, booted for root ADB from LineageOS Recovery via fastboot -s XXXXXXXX boot lineage-recovery.img.
Bash:
$ adb --version
Android Debug Bridge version 1.0.41
Version 31.0.2-7242960
Installed as /opt/android-sdk/platform-tools/adb

Trying to follow some 4-6 years old online guides & QnAs (mostly written by Irfan Latif) on how to backup stock ROM & partitions using adb pull or adb exec-out.
All of these materials always reference an mmcblk0 partition. But in my case it is missing.
What I have instead are these:
Bash:
$ adb -s XXXXXXXX shell 'ls -al /dev/block' | grep -e '^[^d]'
total 0

Which one of those is the new mmcblk0? Which one should I pull to have a full backup of my device stock firmware as an .img file?
mmcblk0 is the internal NAND which contains the n partitions ( mmcblk0p1 ... mmcblk0pn ). Whereas mmcblk1 is the external SD-card.
Try this to backup NAND
Code:
adb exec-out "cat /dev/block/mmcblk0 | gzip" > C:\emmc_copy.zip
Take note that this operation can take very long ( a few hours ).

The problem is that there is no mmcblk0 nor mmcblk1 on my device. Or maybe they were made invisible or somehow unlisted for ls.

Where can I find which ones even exist to compare my situation against?
Code:
adb shell "[ -e '/proc/mtd' ] && echo 'is MTD layout'"
adb shell "[ -e '/proc/emmc' ] && echo 'is EMMC layout'"
adb shell "[ -e '/proc/dumchar_info' ] && echo 'is MTK layout'"

None of the above.
Really weird. No more clues by me. Sorry.
