[Q] Update from 3.1 & Tiamat 1.4.4 failed

Help for a newbie.
I followed this procedure:
1 - Copied file to sd card and renamed to update.zip (in a windows computer)
2 - turned xoom on and wento to rom manager
3 - wiped user and dalvik cache
4 - Tried to load file from zip, but it was not possible to find the update .zip file.
I get the following message:
E: Can't open /sdcard/update.zip
(bad)
Tried also without renaming and got:
E: Can't open /sdcard/update_US-Xoom-Wifi-3.2_HTJ85B-from HMJ37_stachre-solarnz-boot-img_v05.zip
After many trials rebooted.
System info showed the same 3.1 and Tiamamat 1.4.4
Opened rom manager again.
seleced install rom from sdcard
System backed up info and rebooted.
Had to reload all apps from store.
System info shows I am running 3.1 and Tiamat 1.4.4.
Also I keep receiving a message that there is a system update available.
I can't understand what I did wrong.

Can anyone help?
Thank you

You may have the wrong version of CWM recovery installed. You need Tiamat v3.2.0.0 R4c. If you are trying to flash thru Rom manager it may have had you update to v4.0.0.4 which is not compatible with the external sdcard. If this is the case, re-install the correct recovery version, and then redo your backup so that it is on the external sdcard where it can be safe if you need to wipe/factory reset. You can use Rom manger just to reboot into recovery, or df Quick Boot from the market and use that instead.
Good luck!

Rom manager says it is 4.0.0.4 but when in recovery is say CWM recovery-Tiamat-R4c-100611-1150-cwm or Tiamat v3.2.0.0 R4c ( I don't remember exectly) and the error is the same.
Also, I tried reflash recovery-Tiamat-R4c-100611-1150-cwm.zip from the SD card and get an error.
I really don't have a clue of what to do.
Any help would be welcome.

The problem is that you can't flash anything from the external sdcard with v4.0.0.4. In rom manager, see if you can find"all clockwork recoveries" and find 3.2.0.0. If not, find 3.0.2.8 or 3.0.2.5 and flash one of them, preferably the latest of those I have listed. I think those will at least recognize your sdcard. If you can't do that, you will need to reflash the correct recovery the same way you did when you rooted. Remember, never flash a zip file through adb.
Good luck!

I tried to flash recovery-Tiamat-R4c-100611-1150-cwm.img via adb.
I could flash boot sector. Then I reboot into recovery and try to apply zip from card with file update_US-Xoom-WiFi-3.2-HTJ85B-from-HMJ37_stachre_solarnz-boot-img_v05.zip, but there is a NO at the end of the name of the file and I can't go on.
Trying to rename as update.zip and run apply zip from card results in same error:
E: Can't open /sdcard/update.zip
(bad)
what should I do?
Thank you

possible bad download... download again... also, don't think this would be an update... leave it as originally named, just choose the option to choose which zip file to install from the sd card

It sounds like you are flashing recovery ok, but you keep overwriting it with the stock recovery.
Here is some important information that should help a lot with making your new recovery "stick"and this was taken from the Idiot's guide to flashing...in the Development section, and originally written by publicanimal:
4. Install recovery image (CWM)
Download the recovery image file and save it to your computer
Boot into flash mode with 'adb reboot bootloader'
Install your downloaded recovery image
C:\Documents and Settings\Anders> fastboot flash recovery recovery-Tiamat-R4c-100611-1150-cwm.img
Restart the device with 'fastboot reboot'. Timing is essential here, so be alert when the device restarts, or you will have to redo this section
Enter CWM with the following procedure
Once the Motorola logotype is shown, start counting to 3. At 3, press the Volume Down button. This should result in the text 'Android Recovery' in the top left corner. If it does not work, experiment with the timing ...
When 'Android Recovery' is shown press the Volume Up button. This should invoke the CWM recovery menu. If that works, then congratulations for reaching this far .
Here is a potential pitfall. If you are unable to enter CWM *before* the device boots into Honeycomb, then the newly installed recovery image will be overwritten by the system default recovery. If that happens, or if you see "starting fastboot protocol " your timing wasn't right and you need to reflash the recovery image and try it again.
See original post,below for more information.

Noob Not Sure What To Do Next....

Hi all,
First off, I am not familiar with alot of the technical wording in these forums so I hope that I am able to communicate properly with my issue.
I was not happy with how slow the stock version of this tablet was so I decided to install a custom rom, however, I managed to get to the point of unlocking it but that's about as far as I got out of being overwhelmed with what came next! Here is where I am at:
I am currently on Android version 4.2.1 and my laptop is running Windows 10.
I have downloaded latest TWRP image file and renamed that twrp.img and it is stored in the main root folder of my tablet (SD Card aka Internal Storage). USB debugging has been enabled after I activated the Developer Options.
The custom rom I am looking at is CyanogenMod version 11 which I have downloaded, however it should be noted that on the download page it says that there is no recovery available for this build?? whatever this means? I also downloaded Minimal ADB and Fastboot but when I connect the tablet to the laptop (the tablet connects fine) I type in the command prompt "fastboot devices" but nothing happens.
I am at a point now where do I try to continue with the custom rom? or go back to stock?
Can anyone help with basic instructions please?
Thanks in advance.

Head to the General section and read the Beginners Guide. It's the first sticky, so it's easy to find.
It's your decision which rom you run, but you should give Katkiss LP or Katshmallow a good look.
The latter is the only rom for this tablet that is still under active development.

Can I ask questions in this thread with reference to the beginner guide?

Sure. Ask away

I managed to now Root the device and when I turn on the device in recovery mode it says the following:
Key driver not found.. Booting OS
Android cardhu-user bootloader <1.00 e> released by "WW_epad-10.3.1.14.10-20130601" A03
Starting Fastboot USB download protocol
then it has 3 options - RCK, Android, Wipe Data
I am trying to install 6.0.1 KatKiss Custom Rom (it's downloaded onto the device already)
Thanks

As many times as it takes to understand it. :laugh:
In the meantime I will update post #2 a little.
After installing a recovery you have to:
Format data
Convert /data to f2fs http://forum.xda-developers.com/tra.../guide-convert-data-to-f2fs-twrp-2-8-t3073471
flash Katkiss, gapps and SuperSU in the same session (follow instructions in the OP of the Katkiss thread)

I am not understanding about the installing a recovery. RCK is the stock recovery according to the beginners guide, however it also mentions TWRP.
In order to get KatKiss, what steps do I actually need to do? given where I am currently at?

It's all in my Beginner's Guide - you just have to read it:
Basically the process of flashing a custom ROM on the TF700 involves three steps:
1) Unlock the bootloader using Asus' Unlock tool
2) Install a custom recovery on the tablet
3) Flash a custom ROM of your choice using said custom recovery

This is where I am up to now as per the beginners guide
Place the TWRP file into the same directory as your fastboot.exe.
Again check the connection with
Code:
fastboot devices
If you get the connection, in the command window type:
Code:
fastboot -i 0x0B05 flash recovery <name-of-file>
the error I get says "cannot open twrp" (I renamed the TWRP file that I downloaded) even though this image file has been moved into the fastboot directory on my PC (I downloaded and installed the ADB, Fastboot and Drivers tool)

How did you rename the file? Enable file extensions in Windows Explorer and make sure you did not add a double extension

I renamed the file just in windows explorer and I can confirm that the file name is twrp.img

That's with file extensions enabled? Do you see the extensions for all the files in that folder or just for TWRP?
BTW, which TWRP version do you try to flash? Downloaded from where?

Ok I got past this point, I hadn't added .img to the command prompt.
Now I am in TWRP and attempted to install KatKiss but it came up with "Zip Signature Verification Failed!" Error installing zip file '/sdcard/download/katkiss-6.0_TF700T_026.zip".
It did say that it could not find MD5 file?
I now have 2 options
1 - Wipe Cache/Dalvik
2- Reboot System

Just hit the Home button in TWRP, go back to Install and this time uncheck the box that says "verify zip signature" then flash the rom. It always checks if you have a md5 checksum file, but it doesn't matter if you don't. The flash goes through anyway

Excellent, I successfully installed KatKiss 6.0.1!
Thanks for your help mate!

well, I thought I was in the clear until I realised that I hadn't formatted the data (which apparently is why I don't have file manager and other apps).
I have gone back into recovery to format data and re-flash relevant zip files but now the tablet has frozen during formatting with "unable to mount /data/media/TWRP/.twrps" and also "Failed to Mount '/data' (invalid argument)

Katkiss Marshmallow - Can't run Goggle Services/Play
I converted my TF7000T from 4.2.1 to KatKiss Marshmallow, using TWRP Manager on the installation end. Steps included boot access, rooting, wiping/formatting and flashing. Marshmallow functions fine. My problem is that I can't get Google Play or Google Services to run. I tried one installation that was a 'moderate' Gapps installation. It was completely unstable despite some of the apps actually updating. I then repeated the wipe and reinstall of KatKiss-026 and Android 6.0.1 with a minimal Gapps installation - just Google Play Store and Google Play Services. Google Play Services flashes constantly that it is not working. I am also not able to log into my Google Play Store account. I'm afraid I have an outdated version of Google Play. However, I cannot figure out a way to update Play Store or Play Services. Does anyone have a solution to this problem? If I could download a minimal Gapps zip that contained either the current, or update-able version of these two apps, I would also be in business. Help!!

You are running the wrong gapps package I think. You need to install the pico gapps and only the pico gapps package that is linked in the KatKiss OP.
And you have to flash rom, gapps and Supersu(if you want root) in the same recovery session together in that order. Every time. You cannot just flash a gapps package on MM rom anymore.
ROM, pico gapps, supersu - reboot
Oh - and to start out with I'd highly recommend you wipe, better format data before flashing. Wiping of cache and Dalvik goes without saying right?

Yes I did thanks, I haven't played around too much with it though - I did experience it to be very slow when trying to install Facebook app though. I do plan to start using it more often so time will tell.

[Samsung S8+] Unable to bypass FRP

I would like to install TWRP and after that Lineage OS on my Samsung S8+ (Exynos). So i tried flashing TWRP with Odin (Dream2lte version 3.3.1.0). But i ran into a FRP lock so i googled and try to solve this, but so far i am unable to.
I have the password to my Google account, so i removed the Google account from the phone and removed the phone from my Google account. After factory reset i am still getting an error FRP lock when flashing.
Shouldn't the FRP lock be gone after removing google account and doing a factory reset? I have tried a couple of YT Howto's but they don't seem to work.
How do i remove the FRP lock so that i am able to install TWRP and Lineage OS?
Like i said i know the password to my Google account and i 100% own the phone
(Bypass probably isn't the correct word, i am simply trying to turn it off )

Got exactly the same problem, hence like you, ended up here for help.

Well i fixed my problem (Disable USB debug and OEM unlock, couple of reboots and enabled them and it worked). But after that i broke my phone
I am stuck at the screen saying: An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software.
I know this is meant to scare me (is kinda working...), but i also know that Odin is still working. So as far as i know i have to flash the original firmware now to fix this. But i keep getting the error: Invalid magic string. When i try to also flash a BL file i get the error: ""Secure CHECK FAIL: (BOOTLOADER)" The option Re-Partition in Odin is switched OFF, as far as i know this is okee... right?
I have tried 3 different versions (Android 9/8/7):
https://www.sammobile.com/samsung/galaxy-s8/firmware/SM-G950F/TNL/download/G950FXXU1AQC9/128974/
https://www.sammobile.com/samsung/galaxy-s8/firmware/SM-G950F/TNL/download/G950FXXU4DSBA/259612/
https://www.sammobile.com/samsung/galaxy-s8/firmware/SM-G950F/TNL/download/G950FXXS4CSA4/256485/
This zip files contain a BL/AP/CP/CSC file, i have tried them all at the same time in Odin as well as the AP and BL files seperate. (from one zip file, NOT different version files together of course)
I tried using Smart Switch 4.1 to do the emergency procedure using model nummer SM-G955F with my serial number but before it does anything it tells me this is not possible with an SM-G955F.
They all give me the same result.
Does anybody know how to fix this?

Secure check fail on bootloader is your flashing a older firmware than on the device. Look at the builds 5th from last digit. You need to flash that equal or greater than.
The error screen you see for emergency recovery is ok. It's like a modified version of download mode. Kind of. You can still flash Odin files from said screen. Ii see you've flashed a bit 1. And two bit 4 firmwares. So you must be on a 5 or greater. I don't know the exy bit number but like snapdragon is at or near 7 or 8. I can explain better if you need. But not an exynos expert

But i have just tried this one: G950FXXS7DTA6_G950FOXM7DTA6_PHN and it is not working. But this is the newest one available on sammobile. Still the same bootloader error.
I have tried TWRP 3.3.1.0 and that worked, now i am in the TWRP menu but i don't have the LineageOS 17 + GoApps copied to the root. So i cannot install LineageOS now. What do i do now? My computer sees a SM-G955F but it is not showing any storage, if i can fix this i could copy the LineageOS files to the root...right?

1. If you are on an S8+ flashing firmware for the S8 will cause you issues. Download firmware for the S8+ only. ie: 955f not 950f.
2. If you can't get into the system but can get into download mode there should be a line saying
AP SWREV: B:? K:? S:?
The B:? Is your bootloader version number. You will need to flash the same or higher.
3. How did you install TWRP?
If you don't have an SD card to store files on then after the Format Data stage you can then copy files from pc to phones internal storage.

I am a bit embarrassed, it looks like i have been trying to flash the wrong ROMs last night 950 instead of 955, i am downloading the correct files now and wil try again. Sorry for this dumb mistake!
Just to be sure, i am trying to do this:
https://www.getdroidtips.com/lineage-os-17-samsung-galaxy-s8/
(I do know that this site says S8, but i picked the right files this time and thought the process would be the same)
But i first Flash TWRP with Odin, otherwise i cannot reach the TWRP recovery menu right?
But when i look bullet 5 (not number 5) it looks like i need to flash TWRP from within the TWRP menu. But that is not correct right?
I have placed these zip files on the phone:
lineage-17.1-20200211-UNOFFICIAL-dreamlte.zip
open_gapps-arm64-10.0-pico-20200303.zip
As a zip and unpacked, but when i am in the TWRP menu and i go to install, i cannot find the zip files. I placed them in the highest folder level possible. Why can't i find them now?

I don't use custom roms yet.
Try searching for you device S8+ for installation instructions. Had a quick look the firmware is for S8 only not S8+. Need dream2lit for S8+
Try in separate stages instead of all at once.
I would sort out your stock firmware first get it up and running.
Then install TWRP. Install for S8+ from
http://twrp.me/Devices/Samsung/
They are many guides for this
https://forum.xda-developers.com/ga...pment/recovery-twrp-galaxy-s8-exynos-t3595102
If you need rmm bypass zip
https://forum.xda-developers.com/sa...w-to/guide-root-install-twrp-samsung-t3747535
Get that up and running properly.
Then you can install custom roms,root etc.
In regards to transferring files to phone they need to be a zip file ( .zip ) or an image ( .img ) files to flash in TWRP.
Maybe select internal storage then from menu select sdcard folder check if file is there.

I am using dream2lit.
I have the correct factory stock ROM (now), so i can always go back now. But i agree, my preparation wasn't good enough.
I will look at the links, but for now like i said my problem is that i cannot see my files in TWRP. But maybe that will be addressed in one of your links
With regards to your first link, i used the "Odin Method" so as far as i can tell i did this the right way(https://twrp.me/samsung/samsunggalaxys8plus.html):
Odin Install Method (No Root Required):
You will need to download and install Odin on your PC. Once you have Odin installed, download the proper .tar file for your device from the download link above. Power off your device. Turn on your device using the proper key combo to get into download mode and attach the device to your computer via a USB cable. Use the PDA tab or button to browse to and select the tar file that you downloaded and flash the device.
Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP.

I am using dream2lit.
I have the correct factory stock ROM (now), so i can always go back now. But i agree, my preparation wasn't good enough.
I will look at the links, but for now like i said my problem is that i cannot see my files in TWRP. But maybe that will be addressed in one of your links
With regards to your first link, i used the "Odin Method" so as far as i can tell i did this the right way(https://twrp.me/samsung/samsunggalaxys8plus.html):

Note: Samsung don't have fastboot commands. Have to use button configurations to enter recovery or download modes.
What stage are you at?
It will give me a better idea to be able to help more.

Well i installed Lineage OS 17.1 and Open Apps (lineage-17.1-20200211-UNOFFICIAL-dream2lte and open_gapps-arm64-10.0-pico-20200303) with an OTG plug and an USB stick. After installing i removed the USB Stick. But now i am having a new problem...
When the phone boots it asks: "To start Android, enter your password"
Which password is this? When i enter a password i often use it works but then:
"Decryption unsuccessful
The password you entered is correct, but unfortunately your data is corrupt. (Which is no problem)
To resume using your phone, you need to perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up to your Google account.
(Button) Erase ALL DATA"
Of course i erase the data. Look at the attachment to see what happens then.
I will not give up, will get Lineage OS on this phone, and after that on my Tablet S2 and maybe even on my primairy phone (S10+)
What should i do now? Many thanks for all the help so far, and for help finishing this proces

Mounting data errors in twrp generally ( but not always ) means your device is encrypted/re-encrypted when booting into system. Twrp has issues with encrypted devices.
What version twrp are you using?
Have you flashed the no-verity-opt-encypt zip in twrp. This zip file will prevent device from re-encrypting when booting phone back into the system ( after the Format Data stage / reboot back into twrp)
https://build.nethunter.com/android-tools/no-verity-opt-encrypt/
What is your process of installing twrp?
If you have any passwords etc. installed delete them until after setting up you phone.

To install TWRP
1. Flash twrp with odin - reboot straight into twrp
2. In wipe menu select Format Data ( bottom right )
Type yes to format
3. Reboot back into twrp ( use twrp menu )
4. Flash no-verity-opt zip and if needed rmm bypass zip ( using install button in twrp ).
5. Reboot back into twrp then reboot to system using twrp menu.
6. From system reboot back into twrp.
To check if device is un-encrypted use backup menu - check data storage size ( If reading 0mb then device is still encrypted ).
Note: If all ok I would do a complete twrp backup at this stage ( keep backup on a separate storage device ).
Then you can install custom Rom's as per the installation guide of that Rom.

In twrp main menu
Select backup menu - select ( all ) partitions - select storage location ( bottom left of screen ) - then swipe to backup.
Note:
1. If backing up to internal storage copy/move backup to an external storage ie: PC, sd card.etc.
2. Since you want a custom rom backup of the EFS partition is important.
Rmm state can be found in download mode. It will have a line ( near the top ) saying RMM state. It will either say prenormal or normal /disappeared.
It won't hurt to flash it just in case.

I am really trying to do what you are saying...but when i try to "Format Data" (Step 2) it shows an error "Failed to mount '/preload' (Invalid argument). When i try to install no-verity-opt zip (step 4) at the end it shows the same error "Failed to mount '/preload' (Invalid argument). Which is probably because format data failed?
I am installing the zip from an USB stick with an USB-C to USB-A Converter. I don't think that could be the problem?
As Expected the "Data (excl. storage) is still showing 0MB.

Failed to mount preload seems to affect some users.
You could try after the format data and reboot back into twrp ( using twrp 3.3.1.1 ):
Select wipe menu
Select advanced wipe
Select Preload
Swipe to wipe
Reboot back into twrp
Then try flashing no-verity/rmm zips files - reboot back into twrp.
Normally, for me , after this stage If i still get 0mb I will reboot into the Android system and then back into twrp. Then check in backup menu storage. If ok then try to flash custom rom.

Yes Yes!! After doing the Preload i am able to flash no-verity/rmm zips file.
But Data is still showing 0MB.....
I thought why not give the lineage OS rom flashing another try. That worked, but now the phone seems to hang on a Lineage OS logo with a small circle moving around not straight line.
So i wiped everything again and flashed no-verity/rmm zip file, and will wait what for some advice and what do to next.

Have you tried to reboot into system through twrp ie: reboot menu - system. Let it start normally, reboot into twrp, then check storage size. ( This is after the flashing of the no-verity/rmm zip and rebooting back into twrp ).
As I said I' m not familiar with custom ROMs. I do know that some custom ROMs do take some time to boot up on installation.
But out of curiosity I have a spare S8 and will give it a go.

[Guide][Installation][Fix]Switching from stock ROM to custom ROMs + Installing stock ROM after a brick or other Failures ( Mi A2 Lite - Daisy)

This guide is general guide for the installation of custom ROMs. I will also include guide to install stock ROM on devices which have been bricked or for solving various problem which you may encounter in custom ROMs. There are other guides for the same purpose but most of them are outdated and many of you seem to ignore old guide despite the fact that those guides can be helpful.
This is guide is only relevant for installation of custom ROMs which were released up to the date of posting this guide or up to android version 11. Recovering a bricked device can be done in the same way as to this one but installation instruction for devices with android version greater than 11 may differ.

I am NOT responsible for bricked devices,

EDL FLASHING (For windows only)​
EDL flashing can be helpful when flashing every partition of device is needed either for clean stock base or after brick or after some failure.
EDL flashing can be the final resort when everything else fails.
PREREQUISITES
1) A good USB cable, your phone
2) A PC with either windows or linux
3) Fastboot drivers from google and edl drivers from qualcomm
4) Platform tools from google
5)Fastboot rom. This should be full rom in .tgz format.
6)Xiaomi flash tool (LATEST VERSION AVAILABLE)
Install the adb and fastboot drivers from google. If you are on windows 10 or greater then you can also use "windows update > optional updates" to update adb and fastboot drivers + edl drivers. For the installation of drivers always use trusted sources and don't turn of driver signature enforcement if you can.
Extract the platform tools in a convenient folder, we will be doing our operations from this folder for fastboot and adb opeartions. Extract the fastboot ROM and place that in convenient folder as well. And for xiaomi flash tool extract the zip and launch XiaoMiFlash.exe .
If you can access fastboot in you phone then the phone can be booted into edl mode through fastboot else you have to take out back cover and short the testpoint pins to make the device boot into edl mode (see the attached image ).
If you can access fastboot. Boot into fastboot and type the following command in terminal.
To check if device is connected properly and drivers are properly installed
If no devices is shown then connect device properly with good usb cable and check the drivers.
Code:
fastboot devices
To boot phone into edl mode. This is only possible if the bootloader is unlocked else testpoint-edl is the only option
Code:
fastboot oem edl
The device should be shown as COM device in device manager ( Windows ). If not then either drivers aren't installed properly or your phone isn't in edl mode.
Now click on refresh button in xiaomi flash tool. Your device should be recognized as com device. Set the path to the images folder ( extracted fastboot rom ). Select CLEAN ALL option . If everything is good then click
on FLASH. The flashing process should start now. After the process completes keep pressing power button to boot device into the currently installed ROM.
Just install the rom and setup once even if you're going to flash custom rom next. This reduces various problems which may come in custom ROMs.
If any error occurs then try the following:
Make sure you are using latest flash tool.
Good fastboot rom (shouldn't be corrupted )
Good USB cable and try different ports of the PC.
The flashing should be done immediately after booting to edl. If not then take out battery and reconnect it if you have back cover open(In case of hard brick). Or keep pressing power button and volume down to boot into fastboot and boot to edl mode again from the above instructions(If fastboot is accessible)
For booting to edl using testpoint:
> Take out backcover
> Disconnect battery
> Short the pins
> Flash
> Connect battery after flashing is complete
> Keep pressing power button to boot into system.

qdl flashing ( linux only )​
For very detailed guide github -> bkerler edl
Thanks to DEFXZ and LinkBoi for suggesting this alternative.
Make sure you have platform tools, fastboot rom and other prerequisites to detect device properly.
clone the repository in convenient place
Code:
git clone https://git.linaro.org/landing-teams/working/qualcomm/qdl.git --depth=1
change to qdl directory
Code:
cd qdl
Build qdl tool
Code:
make
Finally flash the rom
Code:
./qdl --storage emmc --include /path/to/stock/images /path/to/stock/images/prog_emmc_firehose_8953_ddr.mbn /path/to/stock/images/rawprogram0.xml /path/to/stock/images/patch0.xml
The paths are the paths to various files inside the images folder which will be obtained after fastboot rom is extracted.

FASTBOOT FLASHING​
PREREQUISITES
FASTBOOT DRIVERS
PLATFORM TOOLS
FASTBOOT ROM
GOOD USB CABLE
PC WITH WORKING USB PORT
See this for meeting prerequisites.
Install fastboot drivers, connect device to PC via USB.
Extract platform tools into a convenient folder.
Extract fastboot ROM into a convenient folder.
Go to platform tools folder ( this will contain files and executable like fastboot.exe) and open powershell or any terminal window there
[ shift + right click and select open (powershell) window here ]
Type this command to see everything worked correctly.
Code:
fastboot devices
If not then check every step properly.
Now execute the script to flash the ROM.
Execute flash_all.bat script for windows PC.
Execute flash_all.sh script for linux PC.
If platform tools cannot be accessed system wide then.
Code:
./fastboot devices
will provide fastboot devices information.
For flashing drag and drop flash_all.bat or flash_all.sh file into the terminal.
Code:
'/media/user001/user/daisy/stock_roms/daisy_global_images_V10.0.18.0.PDLMIXM_9.0/flash_all.sh'
It will look something like this in linux and similar in windows.
If any error occurs the search for particular error. Most of the times the error is due to corrupted fastboot ROM or bad connection between phone and PC.

FINALLY! FLASHING CUSTOM ROM​
STEP 0
Flash(if not flashed already) the stock base recommended by particular ROM, if the ROM doesn't recommend a specific stock base flash 10.0.18.0 from the above instructions.
PREREQUISITES
TWRP or ORANGE FOX RECOVERY
Fastboot drivers and platform tools (details above )
The ROM which you want to flash, choose from here
GAPPS package if rom is vanilla and you want to install it.
Magisk if you want to root.
As you may have known by experience, our device doesn't have recovery partition so, flashing recovery through fastboot isn't possible. For flashing recovery first we need to boot recovery image and then only we can flash it.
If you want to use twrp:
Download both twrp*.zip and twrp*.img and place it in a convenient place.
If you want to use orange fox recovery:
Download orangeFox*.zip and extract it.
Keep both the .zip and .img file in convenient place.
If you have sdcard then copy ROM file, gapps, magisk, twrp or orange fox files into sdcard.
If not then there will be further instructions.
Now, connect the phone to the PC via USB and enable usb debugging. And open terminal in the platform tools folder as in above instructions.
Check device connectivity:
Code:
adb devices
Reboot into fastboot:
Code:
adb reboot bootloader
Check device connectivity:
Code:
fastboot devices
Lets check if the bootloader is unlocked:
Code:
fastboot oem device-info
If bootloader isn't unlocked you won't be able to flash custom recovery into the device. So, first unlock the bootloader. This should be allowed in the developers option of your phone first. This will factory reset the device.
Code:
fastboot oem unlock
Now if everything is good then it's time to boot into custom recovery:
Code:
fastboot boot recovery.img
recover.img is name of image of whichever custom recovery you want to use.
Code:
fastboot boot '/media/user001/storage (1)/daisy/twrp/twrp-3.5.2_9-2-daisy-unofficial.img'
It's like this in my case. You can drag and drop after typing fastboot boot
The phone should now boot into custom recovery. If it ask for decryption then your lockscreen password should work there.
if you want to flash recovery only then find the recovery.zip you want and flash it.
The steps further is also valid for moving between different custom roms. The term used for such process is CLEAN FLASH.
For Flashing custom ROMS :
SOMETIMES FLASHING INSTRUCTIONS MAY DIFFER SO, BE SURE TO CROSS CHECK FOR INSTRUCTION IN ROM SPECIFIC XDA THREAD OR TELEGRAM GROUP
The following action will wipe userdata if not wiped already. Be sure to backup data before these steps. Also if you encounter any future problems full backup from custom recovery may be able to solve most of the problems. So, be sure to keep full backup(including every partition) of your device.
Go to main menu > wipe > select all except internal storage and microSD.
Swipe right to perform wipe.
Install custom recovery by flashing recovery.zip
(This is done in case adb push doesn't work below and sdcard isn't available for flashing)
Again go to main menu > wipe > format data
Type yes and press enter.
If you don't have files in your sdcard then:
push rom file + gapps + other files into your device through adb push.
The command will be something like this:
Code:
adb push '/media/user001/storage (1)/daisy/posp/potato_daisy-11-20210919-dumaloo.v4.2.3+20.Community.zip' /sdcard
If adb push fails to work then you can reboot recovery and simply copy the files through file explorer.
Reboot to recovery only if you had installed recovery after wiping system else the device will soft brick
Now flash the rom.zip by selecting the file and swiping right.
Flash custom recovery if the ROM doesn't contain recovery
We have to change current slot even if we don't want to flash anymore things.
Latest recoveries changes slot automatically So, go to main menu > reboot > recovery
Now flash files which you want to flash i.e. gapps and magisk.
Again, Don't flash gapps if the ROM is of Gapps variant
Most of the roms now have implemented FBE (File Based Encryption ). So, you need to format data before rebooting to system. Again, check for specific ROM installation instruction if that is required or not. If you keep data from previous ROM that won't be considered a clean flash so, for proper clean flash format data before rebooting to system.
reboot system

MOVING BETWEEN DIFFERENT VERSION OF SAME CUSTOM ROM
Dirty flash or OTA ​
Most of the newer ROMs have seamless update ( even the unofficial ones ). The OTA update is simple. Just go to updater ( in settings > system or native app, depends upon the rom). If your ROM is of vanilla version then make sure gapps and/or magisk which you have installed, your ROM and custom recovery all support addon.d survival script. If they don't then you may have to flash everything again after update process is complete.
If custom recovery itself doesn't support update then you may need to choose different recovery or dirty flash ROM from the recovery. Don't worry most of the roms and both the recoveries for daisy support OTA and addon.d survival.
DIRTY FLASH​The process of flashing a ROM on top of existing one keeping the /data partition intact is known as dirty flashing. Such flashing must be done only on different builds of same ROM and it isn't recommended to flash build of lower version on top of higher version.
The steps for dirty flashing:
Download the update package.
Reboot to recovery
Enter password for decryption if encrypted.
Flash the update.zip package.
Reboot recovery, if recovery/rom doesn't support survival of recovery then flash recovery before rebooting to recovery.
If gapps and/or magisk survival isn't supported then flash gapps and magisk, make sure gapps is of the same type which was flashed before.
reboot system

Hi @user-001 thanks for this.

I'm not fully sure what that involves could you break it down the steps a little for me.

1) Yes you should follow clean flash instructions.
2)Changing of slot is done in custom recovery. Precisely in the reboot menu. But newer recoveries automatically switch the slot after flashing the rom , just be sure to reboot to recovery after flashing the recovery zip file.
3) the flash_all.bat script will be inside the extracted rom(fastboot rom) folder. You can use xiaomiflash too for flashing through fastboot.

Hi thanks for the reply,
I'm getting confused with all the various guides all seem to want you to do it a different way.
As i'm wanting Lineage thier instructions are...
Installation:
Download the latest build from here
Download LinkBoi00's version of TWRP here
Reboot to bootloader (adb reboot bootloader)
Fastboot into TWRP recovery (fastboot boot twrp*.img)
Do a factory reset in TWRP
Flash the latest build of Lineage OS
Boot into your new phone

Theres no mention of the edl or fastboot flashing and also the fastbot rom i downloaded doesnt have the flash_all.bat script in the zip file.
So do i follow thier instructions or these ones ?

This guide deals with how to do something rather than what to do, meaning you should always do what particular rom suggests but the way to do this is mentioned here.
edl or fastboot flashing comes under clean flashing with new base, most of the time you aren't required to do this.
The script should be clean_all.bat or something similar just don't execute script with lock in the name(it will lock the bootloader)
And if you're already on the recommended base you don't have to flash the fastboot rom.

First of all, thank you very much for the detailed guide. What you have done here took a lot of work to do but it will help a lot of people (including me) to understand, albeit rudimentarily, the structures and functions of the devices etc.
For all that, thanks again.
When I start using the guide, I will update this post with any questions, such as :
fastboot boot '/media/user001/storage (1)/daisy/twrp/twrp-3.5.2_9-2-daisy-unofficial.img'
why not doing below? (For those who, like me, are not very familiar with linux.)
1. > adb push <twrp.img> /sdcard or same adb push "C:\platform-tools\twrp-3.5.2_9-2-daisy-unofficial.img" /sdcard
( which means push <file> from "adb|platform-tools\ folder" (eg. C:\platform-tools\)
into the root of <internal storage> | /storage/emulated/0 )
2. Reboot from adb to fastboot:
> adb reboot bootloader
3. Boot the image from <internal storage>:
> fastboot boot /sdcard/twrp-3.5.2_9-2-daisy-unofficial.img
What is the "Red" pointed and "Yellow" addresses"?
fastboot boot '/media/user001/storage (1)/daisy/twrp/twrp-3.5.2_9-2-daisy-unofficial.img'

I followed your "EDL FLASHING" post (#2) and it worked exactly as you mention!
In short, I was comming from unsuccessful flashing... but this is out of topic.
For me, did not worked the first time (after restarts) but the other day worked perfect.
The point is, most of times, it's becase windowz drivers.
We have to point that windowz needs their time to take the drivers in place. So, be patient and leave windowz to (not forced) restart(s).

That must be your terminal representing different type of character in different colors.
Or, Are you talking about something else ?

For future references, the extracted fastboot ROM should be like this and you need to execute flash_all.bat or flash_all.sh script depending upon your OS or terminal.

Of course I'm talking about something else. lol
I was talking about that 'strange' address. fastboot boot '/media/user001/storage (1)/daisy/twrp/twrp-3.5.2_9-2-daisy-unofficial.img' (explained in post #11)
There is not such a directories in my miA2Lite phone. Obviously, it's because you are on Linux or Mac (UNIX). On Windowz 'command prompt' syntax it's slightly different.
Thus, I typed fastboot boot "/sdcard/twrp-3.5.2_9-2-daisy-unofficial.img"
* /sdcard is the root of <internal storage> directory.
** On Windows, double quote the address, if it's include spaces.

The twrp image was on my pc(linux) i was booting directly from pc's terminal. And if you use only adb(or fastboot) then the paths are pc's absolute paths.

Question LineageOS: "Can't load Android System" on first boot.

My new Xiaomi Poco X3 Pro is showing an error screen after some time, like in this post:
https://forum.xda-developers.com/t/cant-load-android-system-lineageos.4314035/
It reads "Can't load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on this device"
This happened so far:
I just unlocked the boot loader of my new phone after week of waiting.
I followed the official lineage instructions to install the OS: https://wiki.lineageos.org/devices/vayu/install
Everything worked including the sideloading via db.
I downloaded those two files for the LineageOS-Site:
- Recovery via fastboot: lineage-18.1-20211203-recovery-vayu.img (recovery works, I can still boot into recovery)
- System via adb: lineage-18.1-20211203-nightly-vayu-signed.zip
I also added Gapps via adb: "open_gapps-arm64-11.0-nano-20211204.zip"
Both adb transfers exited successfully.
After the first error screen
- I tapped Try again,
- When the error occurred again, I tapped "Factory data reset," but the error still occurred. The phone is new, no user data is on the phone.
- I booted into recovery and reset all the data I could. When I tap "Format system partition" it throws an error "E: Failed to open /dev/block/dm-0: No such file or directory. System wipe failed."
- Then I repeated the adb sideload. The error occurs again.
- I removed the SIM card, as someone in the forum suggested this could be a problem source. The error still occurs.
What can I do now?

Update [2021-12-05 Sun 20:09]
It seems to be a Problem with the GApps Version.
What I did Try so far is:
- Install 03-12-LOS and latest GApps via LOS recovery (didn't work)
- Install 03-12-LOS and latest GApps via TWRP recovery (didn't work)
- install LOS Build from 26-11-2021 without GApps (works)
- Install LOS Build from 26-11-2021 with latest GApps (didn't work)
- Install LOS Build form 26-11-2021 with GApps from 25-11-2021 (works)

Just use TWRP, flash ROM and AFTER flashing ROM Format Data where you have to type "yes". (Format, not Wipe)

Thanks for the Idea. At the moment it has not solved the problem.
This is what I did:
- Flash TWRP
Code:
fastboot flash recovery TWRP-3.5.2-vayu-Nebrassy-2.img
- copy lineage-18.1-20211203-nightly-vayu-signed.zip and "open_gapps-arm64-11.0-nano-20211204.zip" to the Poco device
- install via "install" option, wipe cache at the end of installation
- Format files (via "Wipe" -> "Format Data" -> type "yes")
- Reboot
After some time of the animated Lineage OS logo, the phone reboots into TWRP.
To me this seems very similar to the Lineage recovery before.
Any ideas what could be wrong?

You probably wiped System or Vendor partition or something, you are not supposed to do that.
Most likely you have to reflash MIUI now first. Make sure it's atleast version 12.5.X.X.
Flashing instructions are really simple, this apply to all ROM's.
FIRST INSTALL?:
Remove any fingerprint, PIN, or password in MIUI
Unlock the bootloader
Transfer ROM to internal storage
Install any suitable recovery
Flash ROM zip file
Do a data wipe in recovery (format data)
Reboot to the system, wait and enjoy
FLASHING UPDATES?:
Download via OTA Updater and let it automatically install; OR
Download an update, transfer to internal/external storage (always check file sha256)
Flash ROM zip and reboot.
Do not wipe anything else or add any additional steps. (maybe except Gapps if ROM doesn't have them included)
ps.
In first post there is no mention if you did Format Data or not and when you did it. Like i said before - you have to Formata DATA AFTER flashing ROM . Not before.

I followed the LOS Install Guide: https://wiki.lineageos.org/devices/vayu/install But this procedure does not seem to bee the cause (see below).
Download the LineageOS installation package that you would like to install or build the package yourself.
Optionally, download an application package add-on such as Google Apps (use the arm64 architecture).
If you are not in recovery, reboot into recovery:
With the device powered off, hold Volume Up + Power. When Xiaomi/POCO/Redmi splash appears, release Power and keep pressed Volume Up until recovery appears.
Now tap Factory Reset, then Format data / factory reset and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage, as well as format your cache partition (if you have one).
Return to the main menu.
Sideload the LineageOS .zip package:
On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
On the host machine, sideload the package using: adb sideload filename.zip.

Okay so this is what I did (the part that works):
- I downloaded the latest possible stock ROM from https://www.xda-developers.com/down...ut-several-xiaomi-redmi-mi-poco-devices/#vayu The fastboot ROM is more than 5GB.
- Extract the file "vayu_eea_global_images_V12.5.3.0.RJUEUXM_20211015.0000.00_11.0_eea_05cc38de43.tgz"
- then connect the phone via USB cable in fastboot mode and:
Bash:
cd ~/Downloads/vayu_eea_global_images_V12.5.3.0.RJUEUXM_20211015.0000.00_11.0_eea
/bin/bash ./flash_all.sh
- The default MIUI starts flawless, as it dit the first time I turned on the phone. So far so good.
What didn't work:
1. I installed the LOS Recovery again and flashed the OS and Gapps. Only after that I did step 3 - formating. The result ist the same bootloop as in the beginning.
2. I flashed the stock MIUI ROM again (which woks fine). Then I flashed TWRP, transfered the OS and GApps file and installed. I did not wipe anything, just used "format data" like above.
In both cases the OS does not start. After a while displaying the LOS-logo the phone reboots to recovery.
What did work:
I downloaded lineage-18.1-20211126-nightly-vayu-signed.zip, one version before the latest verion and the corresponding recovery lineage-18.1-20211126-recovery-vayu.img
I flashed only the OS, and no GApps -- and it launched successfully. Installing with the latest GApps failed again.

Install older gapp, not all gapp is compatible
