[Completed] only stocked recovery.img ... (Acer z160 liquid z4)

Hi all,
my problem is on Acer Z160 (liquid z4) :
First nothing for my help on the official site

}
Now the situation :
* only original recovery (and screen's boot
*no access for "usb debugging" ; so no access to adb functions from my pc
* and I don't have original rom ... (only this SPFT firmware)
what is the/a solution ?
First I've read (on XDA forum) : "You cannot flash zip files through fastboot. You need to download a twrp image and flash it individually with" so I've tried but it is not possible :
Code:
fastboot flash recovery recovery_twrp_by_rw-Z4.img
sending 'recovery' (6070 KB)...
OKAY [ 0.209s]
writing 'recovery'...
FAILED (remote:
partition 'recovery' not support flash)
finished. total time: 0.224s
Secondly, and after reading in XDA forums , I've tried to update :
a)
Code:
./fastboot devices
mt6572v1_phone fastboot
b) wipe
Code:
./fastboot -w

but nothing, this action never stop. (problem writing ? permissions ? other ?)
c) update

I'm really disappointed : thanks for your suggestions

remark : the link for download stock rom for recovery is broken on Acer z4 rom :
I've downloaded SPFT Firmware Acer_AV052_Z160_1.015.00_EMEA_GEN1 (Dual SIM)
but it is not possible for Stock ROM for Recovery

[Resolved]
Acer Z160 <==> processor Mediatek

Thanks to xda forum for the link (SPFT Firmware) ... and for all the tutorials )

Boot is in RAW, can't flash with fastboot[SOLVED]

So, I managed to wipe my filesystem when trying to root (going by the board that happens way too often I noticed).
I posted about it here https://forum.xda-developers.com/showpost.php?p=80579913&postcount=295 first.
But despite the quick and nice suggestions it still won't work.
Going by https://forum.xda-developers.com/showthread.php?t=3984875 I also tried to flash boot.img for Fastboot.
Yes, it's the right model ( GM21BA ) for Europe/Global 12gb/256
From make_f2fs.exe I get the following:
PS C:\temp> .\make_f2fs.exe [SERIAL]
F2FS-tools: mkfs.f2fs Ver: 1.9.0 (2017-11-13)
Info: Disable heap-based policy
Info: Debug level = 0
Info: Label =
Info: Trim is enabled
Error: Failed to get device size!
Click to expand...
Click to collapse
Which has me thinking the filesystem is gone.
And then I erased and formated boot twice, and am still left with RAW fs.
PS C:\temp> fastboot format:ext4 boot
Warning: boot type is raw, but ext4 was requested for formating.

And then I tried F2FS with Fastboot Format:
PS C:\temp> fastboot format:f2fs boot
Warning: boot type is raw, but f2fs was requested for formating.
Formatting is not supported for filesystem with type 'f2fs'.
Click to expand...
Click to collapse
So, as I'm writing this I'm reading up on make_f2fs to have it format a new 'boot' for me to flash unto.
Well, at least I have fastboot even if I can't seem to manage flashing anything, so it could be lot worse...

User MSM tool to restore to factory default. It will ease everything, but you will have a working phone. Follow the directions on the thread located here.

For future reference, I'll write how I did manage to fix this:
I had tried using MSM earlier, but couldn't get the qualcom-drivers installed (as mentioned in the thread linked).
So, I tried having the tool already active (and certificates installed) as I pressed both volume up & down and plugged in the phone.
Now a port reacted and I could (with great excitment and haste) press install:

How To Guide [CLOSED] Deleted

Here was a Guide. Someone said people don't care about Me or My Work so...​

there is no Xperia 5 III or even the Xperia 1 III at the Sony Website

I Think you can use xperia 5 II. For xperia 5 II was Xperia 5 the right option before Xperia 5 II was listed

You get this Info from SONY, and it just makes Sense... You don't have trouble if You can relock Your Device. So stop spreading random Infos like "nulls Your Warranty". No One here complains about that...

Basic knowledge for all Tech around the World before You continue with anything of this:
ARM = Mobile Chips
ARM64 = Mobile Chips with 64Bit Support
X86 = Desktop Chips like from AMD or Intel
X86_64 = You guessed it? Desktop 64Bit Chips...
GMS = Google Services or Google Apps
You want to use an Xperia Mobile Device with GMS?
ARM64 GMS... No GMS no Play Store...

i don't get it where i have to look for this sin file
3. Extract the File boot_********.sin with the Unsin Exe (Drag and drop the Image on the Exe)

To be honest with everyone, I don't have much time usually but I do my best to help out if I can! I have many Projects running and writing Guides isn't my Top Priority. But I will rework them ones more! Thank You for pointing out that part of the Guide!

Can i Lock the Bootloader with Root Access?

Hi @Miustone ,
At the GSI flashing stage, I am getting an error.
fastboot flash system_a system.img
Click to expand...
Click to collapse
returns FAILED (remote: 'No such partition.')
Click to expand...
Click to collapse
I tried dropping the _a but that didn't help.
My eventual goal is to replace the MBN files following :https://forums.oneplus.com/threads/...ell-volte-and-vowifi-calling-working.1284987/
When I try to access su from adb shell, I just get a cursor that doesn't seem to execute commands. But doesn't give the error from before rooting. So I'm semi rooted?

[DEV] "Empty" userdata-Partition of AVD/Genymotion Emulator

Hey,
i want to analyse the partitions of my Android Emulator using Autopsy for a prototype i am developing. I started with the userdata partition. However, it seems like that the partition does not contain any data, even though i produced some data (installed apps, phone calls, messages, browsing, etc). It is basically "empty" besides the default stuff that was already there before producing data (see the picture at the bottom). I dont really understand why this is the case. I also tried to reboot the emulator as i thought that the data i produced might be cached somewhere and is written to the userdata partition during shutdown (i checked if the generated data is still there after the reboot). Still, the size of the partition did not change. Other images (not created by me), which i analysed using autopsy during my digital forensic class, contained way more data in der userdata partition and were also produced using an emulator. Besides the AVD Emulator i tried the Genymotion Emulator. Nothing changed except the mapping.
This is what i did to extract the userdata:
1. Launched the emulator (latest API Level) and generated some data
2. Checked the connection via ADB (adb devices)
3. Become and verify root (adb root; whoami; id)
4. List the partition mapping (adb shell; ls -l /dev/block/mapper/)
emulator64_x86_64_arm64:/ # ls -l /dev/block/mapper/
total 0
drwxr-xr-x 2 root root 160 2022-03-26 11:09 by-uuid
lrwxrwxrwx 1 root root 15 2022-03-26 11:09 product -> /dev/block/dm-2
lrwxrwxrwx 1 root root 15 2022-03-26 11:09 system -> /dev/block/dm-0
lrwxrwxrwx 1 root root 15 2022-03-26 11:09 system-verity -> /dev/block/dm-4
lrwxrwxrwx 1 root root 15 2022-03-26 11:09 system_ext -> /dev/block/dm-1
lrwxrwxrwx 1 root root 15 2022-03-26 11:09 userdata -> /dev/block/dm-5
lrwxrwxrwx 1 root root 15 2022-03-26 11:09 vendor -> /dev/block/dm-3
5. Extracted the partition (adb pull /dev/block/dm-5 /DESTINATION_PATH)
6. Renamed the file to .img and created a new autopsy case
I expected the image to atleast contain data within the /app and /data folder.
Also: I would like to know if there is a possibility to extract the whole file system using the ADB only.
Thanks in advance!

you have too name the system_new.img the same name as stock one was and add back the .ext4 on the end you may also have to turn it back into a sparse image for odin to flash it successfully
