Hi My A6000 phone got factory reset and then I tried to recover some lost pics...but I was advised that my phone needs to be rooted first, so the software opened kingo root soft, It showed me the message that phone has been rooted and when it rebooted there was a notification of software update which I said ok and ever since then the phone is stuck on system recovery mode (not sure if it is called soft brick or not) and I have tried many things including choosing all the options starting from reboot system now, apply update from ADB, wipe data/factory reset, wipe cache partition, apply update from sdcard but nothing seems to work!!! oh I for got to mention on the top of the screen it says Androoid system recovery <3e>Kraft -A6000_S035_150507 and then gives all the option and i have tried this following :
https://boycracked.wordpress.com/2015/06/03/unbrick-lenovo-a6000/
but some how for the first solution it keeps on saying download failed, emergency recovery download failed...anyways it does not work
I have also tried this
http://forum.xda-developers.com/chef-central/android/unbrick-lenovo-a6000-plus-lenovo-a6000-t3137247
but it has ADB killed (tried looking and installing adbfixer solution--it says it cannot finf adb.exe even though it is there)
Is there any soultion to this!!! Please help if there is one!
the link from boycracked (mentioned above )actually worked the trick was to hold vol up+down key (while the phone is off) and then insert the usb into your computer, secondly my computer kept of saying that qualcomms --digital signatures not verified and the port is supposed to be Qualcomm Lenovo HS-USB QDLoader 9008 where as mine showed up to 9091, to solve this I uninstalled the drivers and then disabled digital signatures (use goggle how to disable signatures verification on whichever windows you are using) and it worked fine. Thank you all
install cwm
Install cwm from pc and then try
Use HW flash tool
Even my Lenovo a6000 plus was bricked. But mine is more complicated than your's.
I've installed CWM recovery before. But unable to access it, atleast native Android recovery either.
"Rev-app" folder from "System" folder were deleted unfortunately. I couldn't even wipe, hard reset or anything.
After a long struggle, i've found a way out. I've came across a Qualcomm flash tool "HW OneKeyDownload Tool".
And finally, i won on it!
Download it from here: docs.google(.)com/uc?id=0B3qYFBKKL2hieDM1RUNMQWRsSHc
You need to have:
1. Mobile drivers installed
2. Universal ADB drivers (That ZIP will have it)
3. Stock ROM or any custom ROM
See this post on AndroidXDA for more info:
androidxda(.)com/download-hw-onekeydownload-tool
install cwwm
installing cwm from pc is the best way to unbrick
Dont feel bro.just follow the steps which u tried before to install cwm.but before that if ur pc cant find ur mobile.then use this command.
"Adb shell"
And it shows searching for device.
Then put ur battery out and insert it again.ur device will be detect by pc.
Sent from my Lenovo A6000 using XDA Free mobile app
am also getting this same issue. Please help me.

Recently I was tried to update mobile firmware (latest Kraft-A6000-S_S014_150730) by OTA update (via system settings->about phone->system update), that time my mobile was soft bricked like above you said. I downloaded firmware and installed then some time after got some options menu. And I attached that problem as picture.
Before that I rooted my mobile using KINGROOT apk v4.0 , there after I did unroot again using in the same app.
I thought unrooted mobile does not affect by system update (any firmware or OTA update by LENOVO). But unfortunately my mobile got problem.
I didn't took any backup before that. I don't know anything about CWM backup and all. I know only the root and unroot using KINGROOT app.
I need to recover my mobile back or tell me how to install LENOVO A6000 PLUS stock ROM or any other way is there tell me to solve the problem. Please guide me step by step process or any video link there it was little better to understand for me.
Please help me, it will be appreciated. Thanks.
Attach the device to PC through USB cable and Install the CWM through ADB .
Install the Stock Kernel through Update Zip option within the CWM.
That will freshly installs the Android OS.
Hello everybody !
I 've spend a long time on this forum and i've found a lot of interesting and useful tips.
I'm in a bad situation today and I can not find a solution so i thank you for the time spent reading this.
Yesterday i've seen an icon on my desktop and i couldn't remember what application it is. I clicked and it was the beginning of an endless nightmare... A huge lag began by making the phone unusable and apps was installing one after one...
When it has calmed down a bit, i tried to install cleaning softwares but i couldn't do anything so I tried to do a factory reset. After that... the malware was still here... So i've decided to clean all by installing a new ROM.
This is a Jiayu S3 4G 5.5 Inch MT6752 Octa Core RAM 3GB 1080P Screen Dual SIM 4G LTE Mobile Phone (invoice description) so i wanted to try the CM12.1 for Jiayu S3 (found on needrom).
My phone was Rooted and TWRP was installed so i've copied the ROM files on a SD card, rebooted in recovery mode, wiped cache, data, dalvic and system and tried to install the new ROM. it was abnormally rapid and now the phone bootloops.
The only thing i can do is activate Fastboot (if i choose normal boot or recovery it continues to bootloop).
I've tried to flash recovery with :
fastboot flash recovery recovery.img
but i get an error message : FAILED (remote : partition 'recovery' not support flash).
Does anyone has ever been in this situation and solved it ?
Thanks for your help !
Hello,
I got exactly the same problem. Did you find a solution?
My phone is in a bootloop, I can only access to the fastboot mode. (fastboot devices show my device).
In this mode, I can't flash my recovery.img:
fastboot flash recovery recovery.img --> partition 'recovery' not support flash.
I can't see my device with the command adb devices (adb devices doesn't show my device, I think because USB debugging is off, but i can't switch it on)
Did someone find a solution ?
Any help would be appreciated, thanks !
That's the behavior of a wrong preloader that was flashed / malware that affected preloader.
Grab a full spftools ROM set, and flash the entire ROM using " upgrade mode"
Cheers
PS: on s3 you need to have both volume buttons pressed, then you can press download on the spft.
PPS: this will destroy all of your data, so back it up first ..
Thanks for your answer.
So, I downloaded latest version of Flash_Tools, but i can't find any complete set for flashing... only recovery.img (I'm searching on needrom.com). Do you have a place to find these?
>PS: on s3 you need to have both volume buttons pressed, then you can press download on the spft.
I think i got another problem: with Flash_Tools, I'm unable to flash anything to my device... There is a special mode to launch, as you explained, but it seems I can't access it... By pressing both up and down volume button, the phone should boot on a special mode ? How can I know if the phone is booted in this mode ? The USB cable must be plugged before/after booting the phone in this mode ?

There is no special mode, please serach the forum on how to use sptools, i am sure you will find plenty of them.
Sorry for late answer !
Thanks for this advice, i will try as soon as possible and post if it's ok or not.
Hello everybody !
Ok, I got it !
My problem came from the drivers... But not the ADB drivers, the preloader drivers.
In the Windows device manager, when I plugged my phone (previously swithced off), I got a "MT65xx Preloader" device with a warning. Be careful, this item stay 2 or 3 seconds before disappearing ! This driver wasn't installed correctly, that's why Flash Tools didn't worked for me (it didn't see my phone) !
So, I got the driver on the web, by typing "MT65xx Preloader driver", I got the drivers that I installed. This guide gave me the files and a method to install them:
http: //laurentiumihet.ro/sp-flash-tool-mediatek-mt65xx-drivers-download-and-installation-guide-including-bricked-devices/ (can't post links, delete space after http: )
To install the driver, you can set up manually by right clicking on the "MT65xx Preloader" > "Update drivers". Then, browse to the drivers you previously downloaded (a folder containing .inf and .sys files). Windows should detect the driver and install it.
To check if the preloader driver is correctly installed, power off your phone and unplug it, them plug it. Instead of the previous "MT65xx Preloader" entry, you should now see a "MediaTek PreLoader USB VCOM Port" under "Ports (COM & LPT)" (same as before, this item is displayed only 2-3 seconds...).
Now that the preloader driver is correctly installed, Flash Tools works for me. I successfully flashed a new rom I got from needrom.com (a full set, as suggested by superdragonpt), and my phone boots now =)
Thanks all for your answers ! Xehon, hope it will works for you !
Thanks mick605 !
I travel for work so i can't try all the advices on this forum atm.
I'll check this when i get back home and i'll tell you if it's ok
Thanks again !

First of all hi I'm new in this thread,
I have installed everything correctly but I still have only 3 seconds before my phone showes the the charging icon and disconnects.
Can anybody please help me? I actually have been stuck with this problem for months now and all these months I have been using the samsung galaxy s advance (launched in 2011) on marshmallow.
Hi to all.
I landed on XDA because I am not able to hack my Asus Zenfone Laser 2 dual-sim (ZE550KL, which seems to be also called as Z00L or Z00LD... I don't know why... ?!? ). Actually I'm very new on smartphone hacking, so I did my best recently to understand what "rooting", "recovery", "brick" etc mean.
I tried to enter this world because my phone gets gradually very slow as I use it and so I supposed that erasing the pre-installed applications and overclocking it would help, possibly installing a lighter and more performing custom rom. In order to do this I read that in short I have to unlock the boot loader, root the phone and then eventually install a custom rom. In fact I suppose that getting root privileges should already do the job by keeping the original rom, unistall all unwanted apps and eventually overclocking it. Is that correct?
However, the problems I found on my way are the following two:
I've not been able to follow those procedures on Linux. In detail, I'm not able to use "fastboot boot" instruction because it gets stuck on "waiting for any device". The device is listed and allowed when running "adb devices", the boot had been unlocked previously, the phone is in debug mode etc... but the problem is still there despite I've been trying with both the adb package included in the repositries and the one downloaded from the related google page. I've been told it may be a matter of USB drivers, so I also installed the android studio package thinking it would help, but I was wrong. I'm quite confused on this, despite I do hope I can hack my phone using my favourite operating system (I'm a Linux user since 2006). If you do not feel like helping on this then I will try on Windows.
After trying the same procedures on Windows 10, I realised that the Android Usb drivers released by Google did not work. I had to install the proprietary ASUS USB Drivers from the official website and only then I was able to overcome on Windows the same "waiting for any device" I had experienced on Linux. However, the phone "bricks". I suppose this should be the technical term used in this field to tell that the phone gets stuck for hours on the boot animation. I tried several times to reboot it, but each time the same story.
Maybe the problem on Linux is that I do not have the proper Android Device Usb drivers installed. In this case, how to solve the problem taking into account that ASUS only released the drivers for Windows?
RECAP: I have my phone bricked now (Android is unable to reboot, but I can do access both to the Power+VolumeUP menu (by the way, what's the name of this menu? Fast boot?) and the Power+VolumeDOWN menu (by the way, what's the name of this menu? Recovery boot?)
So sorry for the long story.
Hope you can help.
Thanks for your attention and best regards.
Uhm... no replies till now?
i dont know how you get this kind of trouble, maybe try other computer? , im using wondows 10, download small package of of fastboot driver and adb driver, flash twrp using fastboot command. all done. then i make full backup using twrp, next flash magisk .now i have root access, any problem or bootloop i just restore the full backup that work.
---------- Post added at 04:53 PM ---------- Previous post was at 04:22 PM ----------
i see a lot of this zen2 laser got bricked on this general forum , you should read some more if that could help
When I had this device, I remember booting a temporary recovery TWRP and rooted it in that recovery. Then once I got rooted, I installed TWRP app and installed a permanent recovery from within the TWRP app, which needed root of course. Then I got everything working.
You can try booting on a temporary TWRP using fastboot then flash supersu or magisk or whatever rooting client you want. Though, I think you need an unlocked bootloader. I'm sure there's a guide around here somewhere
I'm using a Z00T and just installed LineageOS yesterday using Windows 10, following a guide by Android Authority and LineageOS.
Volume Up + Power = Fastboot
Volume Down + Power = Recovery
Sounds like you can get into Fastboot, so I'm wondering if maybe you can use it to flash the recovery image??? (I'm not a dev in any form; try this at own risk)
I'm assuming you unlocked the bootloader already...
In the directory where all your images are, perhaps try flashing the recovery with the following, where RECOVERY.img is whatever you may have renamed the TWRP image to be:
Code:
fastboot flash recovery RECOVERY.img
After it's finished flashing, turn off the phone, then reboot into recovery mode with Volume Down + Power.
Something Similar happened with my phone and looking for answer
Hi All,
I'm new to this but do some hands on reading these forums. Recently i don't know how but my phone continuously boot into Fast-Boot mode. If I try to push some zip file as mentioned i'm getting error related to partition. "failed to write partition."
Can someone help me out with this.
Thank in advance.

I'm using Z00T and Windows 10. Had no issues using the Android Authority and LineageOS guides.
These guides are great but I don't want to lose my data by formatting my bootlooping device, and the drivers asus gives do not work with windows 10, the adb drivers work fine but the asus drivers do not.
Hello there,
I am a very, very, very newbie in mobile and android, event the vocabulary is new, so please be indulgent. Moreover, I am old school and running Linux (opensuse Leap 15.2) and I hate GAFAM stuff.
I got an old Galaxy S6 SM-G920F. I don't have access to it, no SIM card, I'd guess no data. I want to learn how to change the OS (I think the good word is mod) to something like Lineage.
I have read a lot but there has been evolution in methods and I can't find the easy way to do it.
As it seems WINDOWS OS is needed to success, I installed WIN 10 in a laptop (what a chit!). BUT if you have a way to go with Linux, please I'd prefer.
First I wand to know the main part of the process. I think the first on is to unlock the bootloader.
I tried the following in the phone: Press and hold three physical keys of Home, Power and Volume Down. Release them when the screen is lightning, and then press the Volume Up key. I got on the screen:
Code:
ODIN MODE
PRODUCT NAME: SM-G620F
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
REACTIVATION LOCK: OFF
Secure Download : Enabled
KNOX WARRANTY VOID: 1 (0x0500)
AP SWREV: B:5 K:2 S:2
I'd guess the bootloader is unlocked, could you confirm?
Now, what to do? Could you
- Explain the main steps without detail then
- Point me on a good recent HowTo or write it here.
Many thanks for your help
Edit: BTW what does mean debloat and deknox?

Hello,
as I have installed a custom ROM myself on my S6 G920f only a few weeks ago, I can help you out as far as my knowledge goes and as far as I haven't forgotten it. Bear in mind though that I am not an expert and had to look up a lot of stuff myself.
First, after trying many different up-to-date ROMs and after becoming very frustrated, I kind of accepted that there is currently no up-to-date ROM for the S6 that does not have one or the other big flaw. Some didn't even Boot and instead did load for 5 minutes and rebooted into twrp. The critical flaws on the others were random shutdowns, microphone issues ranging from my voice not being transmitted at all to constant feedback where the other person was hearing her or his voice. The feedback issue I experienced on all the ROMs. Also, with the ROM that I thought I could arrange with I noticed that sometimes, randomly, the calls coming in were just blocked/didn't come through for whatever reason. Also, fast charging is an issue and the camera is bad since you won't have Samsung's camera app and the necessary framework that optimizes it. Google safety net was a big issue with the Android 10 ROMs too, but magiskhide props solved that for me.
I'm sure many people have different reasons to use ROMs but for me it was just not worth it at this time. Maybe this will change later. Just wanting to let you know since you asked for it. I found my current happy place with the Marduk Stock Rom which you can find in the S6 Development section. It is based on the stock ROM which is Android 7, I find it to be fast, it has a good battery life and for me it is very stable. Also no microphone or connectivity issues, fast charging works only with screen off, camera is good since it's the original camera app. No google safety net issue.
Now to your questions.
Debloat means the pre-installed apps that you cannot uninstall and that clutter your phone are removed. Deknoxed as far as I know refers to Samsungs knox which is a safety plus as long as you use your phone unrooted but (tries to) restrict rooting and installing custom ROMs etc. Don't know much more than that tho.
Yes, your bootloader seems to be unlocked.
Now install twrp first. Go to twrp website and download the version you need for your phone. To flash TWRP recovery, you don't need odin. I have used heimdall myself and found it to be very easy.
- Install heimdall. You can also install samsung usb driver for linux if you have issues connecting your phone to your pc.
- Boot into Download Mode (For me volume down + home button + power button)
- Have phone plugged in to pc and at least 60% charge
- Start Terminal, Cd into folder with your recovery.img and use this command to install your recovery (of course replace "recovery.img" with your recovery):
heimdall flash --RECOVERY recovery.img --no-reboot
- Now turn your phone off, and since my phone automatically rebooted at this point, try to stop this by instantly using your key combo as soon as the screen turns black to boot into recovery mode (volume up+home button + power). I had issues here. If you don't manage to do this and get stuck in bootloop just boot into download mode again and install recovery once more to try again.
- Now you can download your preferred rom, boot your phone into twrp recovery and connect to your pc to copy, wipe everything in twrp (obviously save any file you'd like to keep) and install your Custom ROM.
- Most ROMs (but not all! read ROM description!) come without GAPPS installed so you will have to download and install it manually after you have installed your ROM (I recommend GAPPS pico for your custom ROM version). You don't have to do this if you don't want to use google applications.
- Before leaving twrp and booting into your OS install Magisk in TWRP(Download latest version and install in twrp after GAPPs).
- Wipe Cache/Dalvik
- Now reboot into System (and don't install TWRP manager system app)
- Install Magisk Manager after after restart
ROMs:
The best LineageOS ROM I have found to be this: https://lineageos.wickenberg.nu/zerofltexx
It seemed to have the least amount of flaws. The bugs for me were no fast charging unless you reboot plugged in. So no fast charging when you plugin and dont reboot and stay plugged in after reboot. Random connectivity issues. Microphone feedback. Camera crashes and camera issues whilst videocalling etc. Google safety net failure by default, but you can fix this with MagiskHide Props.
Haven't tried the Pixel one here but it seems to have the same microphone issue where nobody can hear your voice.
The Marduk Debloated Stock ROM, also here on XDA, is based on the older Android 7.0 but works very well. Lacks the extended settings and features you find on LineageOS, but least buggy and fast and battery efficient.
Have fun

Debloat means the pre-installed apps that you cannot uninstall and that clutter your phone are removed. Deknoxed as far as I know refers to Samsungs knox which is a safety plus as long as you use your phone unrooted but (tries to) restrict rooting and installing custom ROMs etc. Don't know much more than that tho.
Yes, your bootloader seems to be unlocked.
Now install twrp first. Go to twrp website and download the version you need for your phone. To flash TWRP recovery, you don't need odin. I have used heimdall myself and found it to be very easy.
- Install heimdall. You can also install samsung usb driver for linux if you have issues connecting your phone to your pc.
- Boot into Download Mode (For me volume down + home button + power button)
- Have phone plugged in to pc and at least 60% charge
- Start Terminal, Cd into folder with your recovery.img and use this command to install your recovery (of course replace "recovery.img" with your recovery):
heimdall flash --RECOVERY recovery.img --no-reboot
- Now turn your phone off, and since my phone automatically rebooted at this point, try to stop this by instantly using your key combo as soon as the screen turns black to boot into recovery mode (volume up+home button + power). I had issues here. If you don't manage to do this and get stuck in bootloop just boot into download mode again and install recovery once more to try again.
- Now you can download your preferred rom, boot your phone into twrp recovery and connect to your pc to copy, wipe everything in twrp (obviously save any file you'd like to keep) and install your Custom ROM.
- Most ROMs (but not all! read ROM description!) come without GAPPS installed so you will have to download and install it manually after you have installed your ROM (I recommend GAPPS pico for your custom ROM version). You don't have to do this if you don't want to use google applications.
- Before leaving twrp and booting into your OS install Magisk in TWRP(Download latest version and install in twrp after GAPPs).
- Wipe Cache/Dalvik
- Now reboot into System (and don't install TWRP manager system app)
- Install Magisk Manager after after restart
ROMs:
The best LineageOS ROM I have found to be this: https://lineageos.wickenberg.nu/zerofltexx
It seemed to have the least amount of flaws. The bugs for me were no fast charging unless you reboot plugged in. So no fast charging when you plugin and dont reboot and stay plugged in after reboot. Random connectivity issues. Microphone feedback. Camera crashes and camera issues whilst videocalling etc. Google safety net failure by default, but you can fix this with MagiskHide Props.
Haven't tried the Pixel one here but it seems to have the same microphone issue where nobody can hear your voice.
The Marduk Debloated Stock ROM, also here on XDA, is based on the older Android 7.0 but works very well. Lacks the extended settings and features you find on LineageOS, but least buggy and fast and battery efficient.
Have fun

Thank you waffelschnitten (no waffel icon) for your extensive answer.
I've learn a lot yet.
As this phone is for experiment, I'll try your Howto.
Forgive my ignorance but the first step is not clear for me. TWRP looks to be an Android app. So I have to install it on the phone, but as I mentioned in my previous post I can't access in it, I don't have the code.
Is it possible to bypass the code? Maybe this device is only good for the recycling? Could you be more accurate in the process?
No worries. No your device should be fine.
TWRP stands for Team Win Recovery Project. It is a Custom Recovery System, it's not an app. You don't need to boot into your System OS to install it. You have to flash it onto your phone by using the Samsung Download Mode. Only with a Custom Recovery System such as TWRP you can easily install new ROMs, Root your phone etc.
To install TWRP, you first need to download TWRP for the S6 onto your PC: https://eu.dl.twrp.me/zeroflte/. Download the .img file version.
Now you have to boot into the S6 Download Mode. To do this, make sure your phone is turned off. Then boot it up by pressing and holding Volume Down Button+Home Button+Power Button at the same time for a few seconds. This should get you into Download Mode.
When in Download Mode, connect your phone to your Linux PC via USB.
Make sure you have installed heimdall on Linux. Start Linux Terminal. Remember, your phone should be connected to your PC and in Download Mode. Now check if heimdall detects your phone with this command:
heimdall detect
If it is not detected, try and install Samsung USB drivers for Linux.
If it is detected, navigate to the folder with the TWRP file in your Linux Terminal with the Cd command.
Then, flash your twrp.img file on your phone with this command:
heimdall flash --RECOVERY recovery.img --no-reboot
Replace recovery.img with your twrp.img file. For the latest one it should be twrp-3.3.1-0-zeroflte.img
So this would be the command:
heimdall flash --RECOVERY twrp-3.3.1-0-zeroflte.img --no-reboot
Just to make sure, do you know how to navigate/use the linux terminal?
If you have followed these steps, you should have installed your Custom Recovery. With this you have access to your File System etc. Continue as described in my first reply. As already said, to boot into your newly installed TWRP recovery, you have to press Volume up+Home Button+Power Button at the same time and hold for a few seconds, even after the S6 logo appears.
Many, many thanks,
I am not too bad with Linux, user for around 10 years, only newbie with mobile devices and Android.
I had to wait long time for the battery be empty and the phone power off. I can't find other way with buttons.
I did a download mode restart and connected to my Linux box. Then detect OK, then flash the phone.
Code:
heimdall flash --RECOVERY twrp-3.3.1-0-zeroflte.img --no-reboot

You can force your phone to turn off by pressing Vol- and Power Button together and holding it until it turns off, maybe this helps. Good luck!
Very good, now I am in TWRP and I have a lot of questions.
I did WIPE, Format Data, "yes" and Back.
Should I reboot now? What will be the OS/ROM at self reboot? Should I reboot with Vol up, Home, Power instead?
I connected the phone to my linux computer but no connection.
How (with detail as you did perfectly) to upload the new ROM image to the phone?
As you are happy with Marduk Stock Rom, I'll try it.
Could you provide the link to the thread and the download to this rom?
Thanks a lot again
Edit:
In Marduk Stock Rom, is there any GAFAM app/link/account needed?
Is the version v4.5 (12/10/2019) the last one?
Is it the good link to the thread?
Edit 2:
After disconnect and reconnect, I got the phone in my file manager in Linux (Internal Storage). I can transfer the rom file. What should be the extension of the file? .img or .zip or other? Waiting to your confirmation for the version.

Advanced Wipe everything (but USB)
If you reboot without going into TWRP you will probably face bootloop. But that's no issue since you can always boot down and up into recovery. In TWRP, you can also go to Menu -> Reboot -> Recovery
If you connect your phone via USB to your PC in TWRP it should be detected, so that is weird. You can try to use different usb cables and USB ports on your PC, you can also try to install Samsung USB Drivers and ADB if nothing helps and try again.

Extension should be zip. Version 4.5 is the right one. Dont forget to flash Magisk after installing the ROM and wiping Cache/Dalvik right after flashing Magisk. Then reboot into OS and wait

Maybe install Samsung USB drivers
More and more I think the issue is in the phone.
When I wiped with: Wipe, Advanced wipe, select all but USB Storage, this selection included "Internal Storage".
Now in this window, I can "Repair or Change File System" directories. When I select System or Data or Cache or USB Storage, and press "Repair or Change File System" button, I get info on the selected item and I could do more. When I select "Internal Storage" instead, I get error: "Invalid partition selection".
As I can;t find it with the file manager, my question is
This directory has issue, is it a real dir or a soft link to a real dir?
How to restore as previous?
Edit 1:
In phone, Wipe page I can read on top:
Wipes Data, Cache and Dalvik
(not including internal storage)
Click to expand...
Click to collapse
What does mean "not including internal storage"?
Should I not wipe it?

You can try to mount partitions in TWRP mount option.
I dont know about the Repair options. I didn't have to do that. Also, I dont think your issue is with corrupted file directories.
I would first try to reboot into DOwnload Mode and try and see if USB works in Download Mode. Maybe ADB sideload is possible in Download mode? I don't know about this, though.
If I were you, I would try to connect it to the PC, install Samsung USB and ADB drivers. If it still doesnt work, connect to a different PC, maybe your Windows 10 OS. If that doesn't work, Flash TWRP again and try again.
Wipe/Cache Dalvik does not include internal storage. That is just to make clear that you can wipe it without losing your os or phone data. You should still wipe it, and it will not block wipe of internal storage.
Following this howto I succeeded to transfer and install the new ROM.
I didn't reboot so far as I have to install Magisk.
I downloaded Magisk-v21-4.zip but I don't know how to transfer and install it as I still can't access to "Internal Storage"
I am in the good way, any help?
Nice. So you used ADB sideload to transfer your ROM onto your device? Do the same with the Magisk.zip and flash it just like you have flashed the ROM. Then wipe Cache/Dalvik and reboot into OS.
I did the same process with Magisk, OK then wipe and reboot without TWRP install.
I had to wait at least 5mn then got the new screen.
It seems to work fine and I started to follow setting.... but I got a Google account to create and other thing like that I don't like at all...
I see this ROM is not what I want but I will try a bit
Thank a lot for your help
See you

Hey, yes this ROM is not de-googled. Sorry for that. Go ahead and try other ROMs. Good job installing the Marduk ROM though and have fun
I spend some time to test some features.
So far I found that the fingerprint is not working.
I removed the Google icon but can't remove the apps in Settings > Apps. Is it possible?
How I could install alternative apps store like Apkpure, Aptoide? There are a lot of them but I don't know if I can trust them.
Do you know trusted app shop, good one?
Later if needed, I'll change the ROM. Just to be sure, should I use the same process as previously: Boot to TWRP > ADB sideload > Install the ROM > Install again Magisk.zip (?) > Wipe Cache/Dalvik and reboot into OS.
Question about Magisk.
If fact I don't understand the usage. I have read it's usefull to root devices. My device is rooted, so why I need it? What is the difference between Magisk.zip and Magisk Manager that I have in the apps?
When I start Magisk Manager, at the top page, there are 2 links "Install" to update Magisk and Manager, both look up-to-date. Strange, as the apps are up-to-date why I see these links? Have you the same?
Thank you for your patience.
Edit:
Just to say I don't have any browser where I could display and download apps. Maybe I should start first to install one. BTW what do you advise as browser outside GAFAM?

You can manually degoogle your phone I am sure, but I would advise you to just install a (stable) ROM that is already de-googled.
You can try lineageOS 17.1 if you want (best version I have found was this: https://lineageos.wickenberg.nu/zerofltexx), or look for older official lineageOS builds in this forum, or just any other ROMs.
My fingerprint sensor works, so I dont know about yours. But it won't work without Google apps, I think. At least not on this ROM I guess.
Yes, if you want to change your ROM later, that is what you would do. IF you want Google Apps and it is not included in the chosen ROM, you would have to install GApps additionally. But since you dont want google, you only need to Root and flash Magisk.
Most people use FDroid for a free App Store I think.
About your Question regarding Magisk:
Magisk.zip is the thing you root your phone with. Usually you have to root your phone again every time you install a new ROM.
Magisk Manager is an App that helps you manage your root permissions, so you can grant root access to apps or deny them. It is also there to hide your root from the google system and from apps that require un-rooted devices. I guess you can't run them without Google safety net etc anyways. Furthermore, there is a repository in the magisk manager app from which you can download various tweaks and scripts etc for your phone and flash it directly onto it, without needing to boot into recovery first.
Yes, I see the same installation buttons even though it is up to date. Maybe it is there to give you the option to re-install things to fix issues.
I would advise using Firefox as your browser.
Thank you again waffelschnitten I learn a lot with you.
So far I installed
F-Droid, APKPure
Firefox, Opera, Brave
Signal but I can't start it because I need to update Google Play Services. I had reading about it and understand it is very difficult to avoid as it is a layer between hardware and software (?).
As you know I don't like GAFAM stuff but I'll be pragmatic and use it unless you know another way.
The issue now is when I start Signal, it ask to update Google PS and I am back to the previous window when I click update button. I checked that it is installed version 11.9.75 and the 2 buttons Disable and Force Stop are grey out.
Any idea how to get ride of this issue?
BTW what Instant Messaging app do you advice/use?
