[Q] Running X Server on the atrix 2

Hi. I saw and interesting blog post where someone was able to run arch linux on a nook color and run X server directly.
thomaspolasek.blogspot.ca/2012/04/arch-linux-lxde-w-xorg-mouse-keyboard_16.html
So I tried to do this with the Atrix 2, and managed to get Arch working fine through chroot but when I try startx there is a problem accessing the virtual terminal and I get this error.
Code:
Fatal server error:
xf86OpenConsole: Cannot open /dev/tty0 (No such file or directory)
So I checked /dev and found tty, tty00 tty01. Assuming that they were simply named differently by the kernel I symblinked tty0 > tty, but unfortunately I get this error
Code:
Fatal server error:
xf86OpenConsole: Cannot find a free VT: Invalid argument
So I'm wondering if there is there any workaround that will allow X to use the VT? Or is some sort of kernel patch/module required? (wich I don't think would be possible due to the locked bootloader)
Also might it be possible to point X to the VT used by webtop?

When I read the article it seemed like a custom kernel was installed. Stock kernels may not be compiled with VT support, anyhow
my t700t is as follows
ls -l /dev/tty*
[email protected]:/dev# ls tty*
tty tty0 tty1 tty2 ttyFIQ0 ttyHS1 ttyHS2 ttyHS3 ttyHS4 ttyS0 ttyS1 ttyS2 ttyS3

I added the -> links myself...
when I run x (using Xorg to start it) it tells me:

so the console is using ttys0 at 155baud
so I'm going to have a look at VT support, though I probably need a custom kernel to get it up and running.

You can start xorg as follows
Xorg vt##
replacing ## with the number of the vt e.g.
Xorg vt0
This gives me a mix of three sperate errors, a file not found if the vt# isn't in /dev/vtt#, and io error if i symlink to a ttys and ad error saying the device doesn't exist if i symink tty0 to tty

[Q] How many Android partition does it have ?

I am newbie on android , and I just though of few question after reading some of the partition. http://www.addictivetips.com/mobile...plained-boot-system-recovery-data-cache-misc/
But what I do not understand is , are those partition a folder or real partition ?
As for commonly known , Windows partition consist of either 4 Primary partition or 3 primary 1 extended partition.
-Master boot record partition
-Primary (max 4 , min 0)
-Extended partition ( multiple logical partition )
What about android ? Let me know whether I am wrong
-/boot ( equal to MBR )
-/system /recovery /data /cache /misc (1 parimary partition with different path like /system32 , /Programs files /My Document and etc)
-/SDcard0 (Extended partition )
External SDcard = something like external hard disk.
Overall any android Device have 2 partition ,1 Primary (/system /recovery /data /cache /misc) and 1 Extended logical ( SDcard0)
Please correct me if I'm getting the idea wrong.

Any expert here able to clear out or confirm them ?

Kindly let me know the correct answer.
I am just a starter

It's a hard question ?
Even for a dev too ?

I'm not an expert but as far as I know :
android has 5 partitions ..
/boot
/system
/recovery
/data
/cache
and there Is the SD card partition
/sdcard
Boot: Contains Kernal and Ramdisk ,, Without This Partition The Device Simply Won't Boot
System: Contains The Entire Android System,Android User Interface and System Apps
Recovery: Another Booting Option For Performing Advanced Recovery And maintenance Operations
Data: Contains The User Data Such As Contacts,Messages ... etc
Cache: Where Android Stores Applications Components and Cache
Hope It Helps

The partition is actually real partition like what we did to a hardisk ?
Possible to have 5 partition on a Flash drive ? as for window , maximum is 4 primary partition .

The question you are asking requires a bit of an explanation, but I will do my best (forgive me if I gloss over some things).
When a windows PC boots up, it initializes CMOS which searches for the hard drive or other boot device based on the order set up in BIOS/CMOS. Once it finds a storage device it attempts to boot that device (i.e. hdd=hard disk drive, eMMC=electronic MultiMedia Card). There is a bit set somewhere that determines what type of filing system is on the drive. In linux, you can see the partition table by using fdisk (devices are located in the /dev folder and look like /dev/sda or /dev/mmcblk0, depending on the type and how many there are). Therefore the command would be 'fdisk /dev/sda' and let's take a look at that...
Welcome to fdisk (util-linux 2.32.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Each partition stores data differently. Windows 95 all the way through Windows ME uses FAT (File Allocation Table) and doesn't use user permissions on files. NTFS (Windows NT File System) is the updated version of FAT which had its evolution and caveats. NTFS is the Windows standard now because it 1) can handle file systems larger than 2GB and 2) has the ability to set user file permissions so only the owner can read/write/execute certain files. Android uses ext4, which is a linux file system. The difference is that linux doesn't have drive letters. In windows, C:\ is your normal hard drive, A:\ is a floppy drive, and all disk devices (Thumb drive, CD ROM drive, tape backup, etc) have a letter and are almost always "mounted". In linux... the "root" is / and every device is either mounted as a subfolder or listed in /dev. So if I do a ls /dev I get this as a result (ls is the same command as dir for windows/dos):

As you can see there are a lot of devices, and some of those are pipes/other linux things. To get a list of BLOCK devices, we can either use the lsblk command or we can go into the /dev/block folder and type ls...

Here you can see my sdcard (mmcblk0) and my primary hard drive (sda). The number at the end represents the partition number. As you cans see, I have 11 partitions on my hard drive on my laptop and my sdcard has 2 partitions (in liunx the first of almost everything is 0 instead of 1).
Those ARE real partitions... but the storage isn't exactly like a hard disk drive. All of the information is saved on memory chips in the phone, whereas a hard disk drive (HDD) uses magnetic dust to signify bits (if more dust is on the top of the sector it's a 1, and if more dust is down it's a zero). Also, there are MANY more Android partitions than the partitions that you listed.... using the "cat" command you can print a text file to the screen in linux (including Android) and the /proc/ folder has a bunch of text files with information about your device. Typing the command "cat /proc/partitions" on my ZTE prints this out...
$ cat /proc/partitions

Each of those partitions stores different information in them. One is the cache partition, which is where all app data is stored. One is for the baseband (cellular radio chip), zram0 is RAM, system contains the Android system file (like c:\windows). Nowadays, there is an frp partition to lock the device if someone attempts to factory reset the device, the account information is still maintained (as the data and cache partitions are formatted but frp isn't, and therefore Android won't let you in unless you supply the username and password). The laf partition has to do with Fastboot (a PC command line program to change the partitions) and there are also vendor, firmware, carrier, and several others that I don't know the purpose of.
I hope this helped you and maybe some other people.

Verizon Pixel Your device is corrupt. Bootloop, locked bootloader, no recovery. Help?

OTA update failed, the phone spontaneously shut off and rebooted to the beautiful "Your device is corrupt. It can't be trusted and may not work properly." screen. After being greeted by said screen, the phone reboots and goes to the same screen. Recovery doesn't boot. Fastboot doesn't allow me to flash any image (even signed from google). If I boot into fastboot and do a "fastboot continue", the phone boots to a blank screen with adb running in recovery mode, but with the port closed (can't flash a recovery OTA).
Someone please help. I've tried all solutions I could think of. I don't know what is left.

Sounds like a trip to a Verizon store is in your future :/

Any chance Google themselves would be able to take care of this?

I wonder if the OP unlocked the bootloader and rooted. If so, they might not take too kindly to replacing the device. If it's stock then head there today and get a new one. How about a factory reset attempt?

Impossible to factory reset. Recovery does not boot. Bootloader is locked, as fastboot flashing unlock returns as invalid.

Same "Your device is corrupt. It can't be trusted and may not work properly.", and recovery fails to boot. Nothing on the display, phone either shuts off or boots to charging mode.

What was your situation before this started? Unlocked? Rooted?
Edit: I see you were updating.

None of the above, stock Android OS.

Recovery is sometimes not easy to get in to. I had to do it 3 times in a row before I got it to take. So I'm sure you know it's hold the power button and then hit vol up. But if you don't get it just right it will reboot or turn off. Does adb work?

Ok so this is getting weirder by the second. Just saw a teamwin recovery screen pop up...
I purchased this device second hand and used it with no problems until the first update, but it definitely looks somewhat tampered with. Any advice?
This occurs when I perform a fastboot continue. At that point I have adb up in recovery mode. But since I see nothing on screen, I can do nothing. Can't sideload because it's not at the sideload screen. Suggestions?
EDIT: Okay, so I have a VERY basic adb shell up through TWRP. I can't access TWRP directly because it "hasn't started". Ideas?
EDIT2: adb shell has basic busybox commands and is running root. I have downloaded a new TWRP image. What is the partition where the pixel has its recovery? Under /dev/block/mmc....?

Can you get into bootloader?
Which slot is active?
Can you
Fastboot set_active _b
Or
Fastboot set_active _a
And try getting to recovery or booting?

b slot is active. Will reboot now and (attempt to) switch to a. Found the appropriate fastboot by googling, please hold...
Code:
Setting current slot to 'a'...
(bootloader) Command is not supported.
(bootloader) Please unlock device to enable this command.
FAILED (remote failure)

What a surprise
Also to clear up, the only way for me to get thrown into this psuedo adb shell in TWRP is to "fastboot continue" at the fastboot screen. Recovery fails to boot. System fails to boot. Fastboot is useless because oem unlock is not possible.

Partition table dumped. Any ideas for where the recovery resides?
Side note: I have never ever seen this many partitions on any device. Ever.

SUCCESS. Stock recovery boots.
Used the gimped TWRP adb shell to push aboot.img and boot.img from a stock rom. And dded them to the respective partitions, on the _b boot slots.

May I suggest unlocking the bootloader now that you have things going better for you?
Did you ever get the system to boot up?

Can't FRP is locked. Guess the FRP partition got screwed.

I have the same problem. I'm trying to follow your steps, but I'm lost
Currently, phone is on Boot-slot: b
Code:
fastboot set_active_a
usage: fastboot [ <option> ] <command>
doesn't do anything
sorry I'm noob. Please help.

How do you have the same problem. You have a locked bootloader with TWRP?

[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]'

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.

OMG. It depends on what partition layout Android OS is based on.
It's on you to find that out.

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.

Need help for the repartitioning of Z3 in order to install Windows 11

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:

What I wanted was:
rm 21
mkpart esp fat32 85MB(84.2MB) 500MB #415MB
mkpart pe fat32 500MB 3000MB #2500MB
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!
