Trapped In Boot-loop, Help! - Samsung Galaxy J7 (2017) Questions & Answers

So, I will preface this post with: I am a noob. I am not very well-versed in technology or costumizing Stock OS, I can use a Stock OS on any Android phone, but as soon as anuthing resembling Coding comes into the picture I may as well be trying to learn how to operate Alien Technology.
So heres the problem: I tried to Factory reset my Samsung Galaxy J7, which had Developer options activated, OEM unlocked priopr to the Samsung Updcate that put Oreo 8.1 on it, so I did have an unlcoked Bootloader. My Boyfriend (Who very much enjoys tinkering with tech-stuff, nd is usually highly proficient at such endeavors) insisted I do some kind of backup, even though I had preveiously backed up everything to my Samsung cloud; I handed my phone over to him and when I got it back it was stuck in a Boot-loop, he said it was Softbricked. So, we did much research to try and get a custom ROM after installing TWRP 3.2.3-0. I decided on a Prometheus OS ROM, and downloded it aswell as the GApps for my phone (ARM+7.1 since the new ROM is a 7.1 OS). I folowed the instructions precisly; but even still it is in a Bootloop, and Idk what to do now, my Boyfriend says he needs to edit the coding on the OS ROM, but this Prometheus ROM is the first one out of countless that has made it past the attempt at installing (Usually I get to the point where I 'Swipe to install' then after a few seconds of instalation it reboots into TWRP as if I didnt do anything; or gives me an ERROR 6 or 7, but this time it says "Instalation compleate, Reboot now?") So, Idk how to fix it but I really really like my J7, and I want to fix it.

Reading that was a bit if an eye attack, one massive hard to read block of text.
To install a custom rom you need to first FORMAT (not wipe) in TWRP.
Then immediately after the install (assuming it installs correctly this time) you need to install Magisk.

Sorry for the text block, I was stressed lol But there was a misscommunication on my part tbh; in order the steps I took were
-Transer downloaded ROM to SD card from Computer'
-Boot into revovery via TWRP
-Format
-Install ROM
-Reboot
-Install GApps
-Wipe Davlik/cache
-Reboot
then, the screen turns on to the default "Samsung Galaxy J7" Bootload, flashes blue for a millesecond then goes dark, and then repeats for all of eternity. And about the Magisk; the ROM installer has an option to install Magisk or SuperSU ROOT, do I need to additionally add a Magisk file? i had checked the option for Magisk last I attempted to flash the ROM

Rooted, Custom Rom a huge fail

Hello dear Community!
It is depressing that my first appearance here is to ask for help, but I am going crazy.
So, I tried to Root my phone via Odin + CF Autoroot klte and it seemed to have been a success.
The root checker also said, that my device was rooted so I went on and installed TWRP to be able to install Lineage OS.
After getting Lineage to work I got a few error messages suddenly popping up, telling me that either "Music had stopped" or other android operation were closed because they didn't work properly.
I tried to install Gapps, it seemed to have worked but I was only able to open and enter the store once, afterwards the store never managed to load and then the app closed itself after starting it.
So I checked again with Root Checker, but this time it gave me an error message, too. It said, that my device was not rooted properly.
I guess this is were I made it worse by deciding to just root the phone again. Obviously, it didn't work either.
Afterwards I thought that maybe installing The Original Android OS and then unrooting the phone would be the best solution to be able to start anew.
First I tried to flah Lineage again and that made it impossible for me to boot the phone. The farthest I got was the setup page, were it tells you Hello and were you can choose a Language, but clicking the arrow key didn't do anything at all.
The recovery mode was also not the TWRP one anymore, but the original Android one and that was a huge problem for me.
Then I tried to flash the 6.1 OS for the S5 (I made sure it was the correct version), but now it is stuck at the "Samsung" screen while it boots.
It never boots though.
I don't know what to do anymore.
Please, I beg you, could anyone help me out?
Don't flash the latest Lineage OS ROM
Hello AsylumAlice u shouldn't have flashed the latest Lineage OS ROM because now u will need a new motherboard for your S5 since the ROM corrupts the MMC chip now u will need to get a new MMC chip or a new Motherboard sorry that your s5 is now hard bricked but when u get it fixed flash the DreamUX S8 Rom it works flawless on my S5 SM-G900i

What are the grounds for your claims?
You needn't root via CF-autoroot if your end goal was to flash lineage. CF autoroot was intended to root stock roms with ease and less effort.
Flash The LATEST, official TWRP via odin then do a FULL WIPE. Wipe system, data, cache and dalvik cache.
From here on, you have two options:
1.) Sideload the LineageOS rom via ADB
2.) Transfer it to the phone's storage via MTP and flash it from TWRP.
As for how to accomplish this, the forum search bar and Google has your back. You need only choose one procedure.
If you need the Play Store, flash gapps AFTER flashing LINEAGE AND BEFORE REBOOTING.
Since you were under the idea that utilizing CF-autoroot was a necessity, I suggest that you re-read this post thoroughly before actually putting it into practice.

Thank you so much for your fast reply!
-> I flashed the newest Version for klte via Odin, but I can't get into the boot mode.
I only am able to enter the download mode. What can I do now?
Flash TWRP via odin again, untick the Auto-Reset option of Odin first. Then try booting to recovery via long holding the power, home and volume up button simultaneously without releasing any of the buttons until you successfully see the TWRP splash screen.
If that still doesn't work, reboot to recovery via adb from download mode. You need the adb and the usb drivers for your device.
If that still doesn't work, you might have flashed an incompatible version of TWRP.

Thank you so much, it worked perfectly!
I can now start my phone and use it normally.
But the Root Checker still says:
"Sorry! Root access is not properly installed on this device.
Device: SM-G900M
Android version: 7.1.2"
What should I do from now on?
Thank you so much for your help (agaiN).
And as for why I used the auto-root, well I just followed a guide that I found, it only had positive reviews so I assumed it was a correct tutorial.

I thought about doing that, but wasn't sure how exactly to proceed and what Version to install.
I downloaded SuperSU v.2.82 and put it on my internal storage.
Just install over TWRP the same way that I Installed Lineage and Gapps I suppose?
I guess if it doesn't work out, I just follow the steps from above again and retry?
Thank you so much. I feel like in idiot in this situation.

How to restore my Recovery-mode (TWRP)

I ran some troubles whilst was turning my android version 4.4.4 into a 8.1, TWRP helped me with the whole process (if it wasn't by those guys i'd have a bricked phone for sure). While fixing things and figuring out all the misstepped nuances on my end it come to my understandment that TWRP 2.7.1, while funcional, was flawed; since the newer versions could get rid of the necessity of dealing with adb and some weird glitches that not even 5.53785% of the internet community has dealt (or at least expressed) in the past. Errors like "broken pipes" or closed doors on a DMZ connection were spreading the adb sideload route that i had avaliable. For that reason i decided to upgrade TWRP, followed these instructions to the heart paying attention to the warning that 2.8.4 version would be needed if i want a recover-mode route for said upgrade, which made me go for the googleplay manner. My mistake was not backuping the image of the working 2.7.1 version which was in place, i've neglected such feature and gone straight to the 'download and flash' an image, which i opted for getting the 2.8.4 planning on upgrading the remanescent versions directly on recovery-mode. I never came to celebrate such accomplishment since the change of 2.7.1 to 2.8.4 via rooted TWRP app made my recovery-mode to BSoD. Ever since i've tried downgrading to 2.7.1 again to see if would at least return to the old point but i ran outta luck here. Whats the best course of action to take right now? Straight up overwrite it using this. Delete and reinstall?
TLDR::: had TWRP 2.7.1, without making backup of the working stance, installed 2.8.4 image via googleplay official app (rooted), got as result? a bricked, black recover-mode screen. Atempted to reroll to 2.7.1 by downloading it on said app, didn't worked, BSoD stay still when recovery-mode is choosen. What to do to get, if not the newest version of TWRP, at least the 2.7.1 back?
First, flash the latest stock OS (Android 5.1.1), then flash the latest TWRP (twrp-3.2.1-0-mako.img) and proceed with flashing selected rom from there.
Edit: don't use some 3rd party flashing tools, they tend to be broken and/or oudated.

Thing is: i'm now using nitrogen 8.1 Oreo, which i manage to flash via a working 2.7.1 TWRP plus the flashing tool that i've used was the one provided and advised by TWRP team themselves, the one official on googleplay. I'm up to downgrade android 8.1 to 5.1.1 but how to do it? (considering that i can't access the recovery-mode)
EDIT: perhaps you're saying for me NOT to use something like this?
I always use Skipsoft android toolkit to flash stock/custom roms.
https://forum.xda-developers.com/ne...olkit-skipsoft-android-toolkit-nexus-t1995688
This thread is over :victory:
This problem is now solved. Thank you both for taking time to express some light on my troubles, thanks for answering my plea.
HOWTO: Talking with a correspondent of official TWRP i was advised to download and flash on the official app (googleplay app, just as before) the previous version version 2.7.0 (considering my last working version was 2.7.1) to see the results. It managed to get me back a working recovery-mode screen and from there, i made the needed IMG backup and recovery backup before following the next step: downloading 3.2.1 straight from 2.7.0 (bold, if you'd ask me, but since i got 2.7.0img backup saved this time, i feared no trouble :highfive and IT WORKED!

Moving from stock Android 5.0.1 to Resurrection Remix N v5.8.5.

Hello community!
First of all, I feel I have to apologize to you all since I know I have clogged the forum with a lot of requests of help about upgrading my smartphone... They are scattered all over the place so I have decided to gathered in a definitive one.
I have edited this post to make it a comprehensive guide for all the people who want to upgrade their HUAWEI P8 LITE ALICE from the stock Android 5.0.1 to the Resurrection Remix N v5.8.5. Before go any further I want you to read the following disclaimer:
PLEASE PLEASE PLEASE READ THIS!!
I am not a developer. I am not a programmer. I have been greatly helped by the user Botar230 so, unfortunately, I cannot help you in case of problems. I myself had problems and had to ask for help. The only thing I can say is to be always polite and try to explain, as best as you can, what's going on.
I will try to be as much clear as possible here but keep in mind that english is not my native language so it is possible that I might mistaking something. My apologize. I am not responsible for any damage you may do to your mobile and I am not responsible to any data loss it may occur. You should ALWAYS do a backup before proceeding. ALWAYS.
I've decided to flash Resurrection Remix N v5.8.5. because it is pre-rooted with Magisk.
BEFORE start to upgrade your mobile, read all this post twice and be sure to understood all the things I have written here. Check the links, check if you have the correct files, check if your mobile is fully charged, check if the bootloader is unlocked, check if you have the right ADB files and drivers downloaded and installed. Please do it BEFORE you start everything.
Done? Everything is fine? So, here we go!
GOAL: Moving from stock Android 5.0.1 to Resurrection Remix N v5.8.5.
MY MOBILE: Huawei P8 Lite ALICE (ALE-L21) unbranded single SIM - Build number: BalongC50B311 - Kernel 3.10.61-gcd3fde7 - EMUI 3.1
BOOTLOADER STATUS: unlocked, checked via ADB
The build number and the kernel number might differ. You should check them carefully and search around this forum how to proceed properly. Also, I totally don't know what to do if you have a double SIM phone. Sorry.
These are the files I have downloaded and put on the MicroSD before starting the whole process:
b895_update.zip
open_gapps-arm64-7.1-nano-20180702
RR-N-v5.8.5-20180302-alice-OpenKirin.zip
The file TWRP_3.1.1-0_ALICE_BL.img have to be put in the same directory where adb.exe is since you will flash it via adb command: fastboot flash recovery TWRP_3.1.1-0_ALICE_BL.img once you have entered in fastboot mode AND you have checked that your bootloader is unlocked.
Now, the next steps that worked for me are:
install TWRP_3.1.1-0 via ADB
Factory reset (Wipe -> Swipe to wipe)
update the device with b895_update to get Android 6.0 and EMUI 4 (by putting b895_update on the SD card and flash it via TWRP previously installed or via sideload as suggested by Botar230. I find myself comfortable to use ADB.)
install again TWRP_3.1.1-0_ALICE_BL via ADB or via sideload
Flash RR-N-v5.8.5-20180302-alice-OpenKirin) via TWRP AND at the same time...
Flash Open Gapps via TWRP. You HAVE TO USE THE ARM64 - 7.1 VERSION!!!
Reboot your device. It is done! :good:
NOTE!! Updating the phone to b895 will take really a lot of time. Seriously. It might be scary but it's ok. It will update EMUI too.
NOTE!! When you install TWRP via ADB, the TWRP_3.1.1-0_ALICE_BL.img file MUST BE in the same directory where the adb.exe file is.
At this point, everything should be fine, working and squeaky clean!
The ROM is pre-rooted with Magisk and that's pretty cool!
At this point I think my brief tutorial is over. If you find out something important missing or wrong, please point it out! It will help other people! Thank you!
Some links about ADB that I found quite useful:
How to Install TWRP Recovery via Fastboot On Any Android Device
How to Use ADB & Fastboot Commands with your Android Device
ADB Shell
Once again I have to thank the immense patience of BOTAR230 and all the people that worked so hard to make everything possible: I mean the guys (and gals? Maybe, I don't know... ) behind the Resurrection Remix ROM, behind the TWRP project and the Open Gapps and the many more I probably forgot! Thanks everyone!

Next, I am quite insecure on all the steps so I will try to make a comprehensive list and keep it updated hoping it will help all the Huawei P8 Lite ALICE users that will do the same process I am about to do. Let's proceed!
GOAL: Moving from stock Android 5.0.1 to OpenKirin's MoKee
MY MOBILE: Huawei P8 Lite ALICE (ALE-L21) unbranded single SIM - Build number: BalongC50B311 - Kernel 3.10.61-gcd3fde7 - EMUI 3.1
BOOTLOADER STATUS: unlocked, checked via ADB
Now, the next steps would be to root the mobile. My wild guess are
install TWRP_3.1.1-0_ALICE_BL via ADB
install Magisk to root Android 5.0.1
At this point I am not perfectly sure if those steps are right AND if Magisk is the right choice to root Android 5.0.1 on my mobile. Are there other ways to do that?
Once the device is rooted, the next steps should be:
update the device with b895_update to get Android 6.0 and EMUI 4 (by putting b895_update on the SD card and flash it via TWRP previously installed)
install again TWRP_3.1.1-0_ALICE_BL via ADB
install again Magisk to root Android 6.0
install pa_alice-7.3.1-EOL-20180203 (or RR-N-v5.8.5-20180302-alice-OpenKirin)
That's the theory. I've used SR5-SuperSU-v2.82-SYSTEMMODE but it bricked the phone after I updated to Android 6.0 and the user Botar230 told me that it is no longer updated and used and suggested me to use Magisk instead.
The files I have are:
b895_update.zip
open_gapps-arm-7.1-stock-20180626.zip
RR-N-v5.8.5-20180302-alice-OpenKirin.zip
pa_alice-7.3.1-EOL-20180203.zip
TWRP_3.1.1-0_ALICE_BL.img
Previously, I have updated my device to Android 6.0 and installed TWRP 3.1.1-0 and everything went really good. When I tried to root the phone with SuperSU-v2.82, it bricked. Now the phone is restored to its initial conditions, brandless.
I have read THIS POST but it's pretty old and most of the link there are not working anymore.
So, if someone is kindly willingly to give me a hand (yeah, another one, I know... ) on this subject, I'd really appreciate it. Again.
Thanks in advance!

I didn't fully understand you, so I'll write a quick guide how to move from stock android 5.0.1 to any other custom ROM (I've read that you already unlocked your bootloader and flashed twrp so I'll skip those two)
First of all, use this version of TWRP.
1. Boot into TWRP
2. Factory reset (Wipe -> Swipe to wipe)
3. Flash B896 update (B895 is fine too)
4. Flash TWRP (Install -> Select image -> Recovery)
5. Flash a custom ROM of your choice
6. Flash Open GAPPS (I recommend flashing NANO version)
7. (Optionally) Flash Magisk if your custom ROM isn't pre-rooted (if unsure, check the root status before flashing)
Fun fact: You don't need to put every file on SD card to flash it. You can also use sideload

Hello Botar230! At the present time, I only unlocked the bootloader.
No TWRP installed so far.
Thank you for adding some steps I have missed (like the factory reset and the GApps! :good: )!!
The TWRP version I have is the same you suggested me so this is fine!
Yes, now that I think about, nearly all the custom ROM are pre-rooted and there's an option to switch the root in the setting panel but I will check it eventually.
I have make corrections in my list after your suggestion:
install TWRP_3.1.1-0_ALICE_BL via ADB
Factory reset (Wipe -> Swipe to wipe)
update the device with b895_update to get Android 6.0 and EMUI 4 (by putting b895_update on the SD card and flash it via TWRP previously installed or via sideload)
install again TWRP_3.1.1-0_ALICE_BL via ADB or via sideload
install pa_alice-7.3.1-EOL-20180203 (or RR-N-v5.8.5-20180302-alice-OpenKirin)
Flash open_gapps-arm-7.1-nano-20180630
Check whether the ROM is rootable and eventually flash Magisk
The files I have are:
b895_update.zip
open_gapps-arm-7.1-stock-20180626.zip (I will not use these)
open_gapps-arm-7.1-nano-20180630.zip (I will use these one! )
RR-N-v5.8.5-20180302-alice-OpenKirin.zip
pa_alice-7.3.1-EOL-20180203.zip
TWRP_3.1.1-0_ALICE_BL.img
Everything looks good now. Btw you don't need to flash nano gapps exclusively, it's just a matter of your personal preference which one you choose.

To be honest, I don't know what to choose between all the options I have seen on the website. Let's say that if the installation works properly it's a matter of seconds to make a backup and try another Gapp. For the moment I will follow your suggestion.
That's what I have done so far:
install TWRP_3.1.1-0_ALICE_BL via ADB DONE AND OK!
Factory reset (Wipe -> Swipe to wipe) DONE AND OK!
update the device with b895_update to get Android 6.0 and EMUI 4 (by putting b895_update on the SD card and flash it via TWRP previously installed or via sideload) DONE AND OK!
install again TWRP_3.1.1-0_ALICE_BL via ADB or via sideload DONE AND OK!
Everything is working fine so far but I am a little bit nervous about these one. I will take a deep breathe and I will proceed right now. I can flash the ROM and the Gapps with TWRP, right? I am mostly sure about but a confirm could ease my fear of bricking the phone again... :silly:
install pa_alice-7.3.1-EOL-20180203 (or RR-N-v5.8.5-20180302-alice-OpenKirin)

install pa_alice-7.3.1-EOL-20180203 (or RR-N-v5.8.5-20180302-alice-OpenKirin) DONE AND OK!
I had to install the open_gapps-arm64 since the system required the ARM64 but apart that...
Flash open_gapps-arm64-7.1-stock-20180630.zip DONE BUT NOT OK! - I've tried to install the NANO and the STOCK Gapps but every time I got the same error message on TWRP: "failed to mount data: operation not supported on transport endpoint". Google Play and all the Google apps cannot connect: the Google error message is always the same: "couldn't sign in". I've double checked the login and they work both on my PC and on the other phones so I'm sure they are correct. Now I'm searching what kind of error it is but I'm not finding much infos about. Plus, there is the warning message saying that "Google Play services has stopped" and it keeps popping on the screen.
Check whether the ROM is rootable and eventually flash Magisk NOT DONE YET but it seems that it is not pre-rooted.
I am searching the web to understand what's going on here.
It's probably because the custom ROM that you've chosen uses f2fs file system on /data partition instead of ext4. Try to do this:
Boot to TWRP -> Wipe -> Advanced wipe -> Choose Data -> Repair or change file system. From here you can see if the file system of /data is ext4 or f2fs. If it's f2fs, then click Change file system and choose ext4.
Before doing all of this, you should flash b895 again, do a factory reset, flash twrp, flash your custom ROM, change /data file system, and finally gapps so there will be no conflicts between old and new gapps.
Hello again!
Sorry for the silence, got some busy day but here I am.
Before doing what you told me, I've tried to do a backup with TWRP and I've been flooded with error messages:
failed to mount '/data' (Operation not supported on transport endpoint)
Unable to recreate /data/media folder
Unable to mount storage
failed to mount '/data' (Operation not supported on transport endpoint)
Unable to mount /data/media/TWRP/.twrps
And, of course, the backup process failed.
At this point I cannot do anything with TWRP.
I cannot backup, cannot flash a ROM or a ZIP.
The phone works fine, it boots and I got no problems. I can boot it via ADB too.
I'm really scared it will brick or loop sooner or later. I am keeping it turned off and wait for any other advice before proceeding since it would be quite pesky to restart from scratch again....
Following your directions I've seen that the data file system is ext3.

Click to expand...
Click to collapse
Don't worry, it won't brick. Maybe the internal storage is encrypted. In order to remove encryption, go to Wipe -> Format data.
Hello Botar230! Something funny (in a very positive way) happened! I did as you told me: I booted in recovery mode and went to WIPE -> FORMAT DATA.
Then I considered to install the other ROM I had, RR-N-v5.8.5-20180302-alice-OpenKirin and it has been the best idea I could have!!! :laugh:
After I formatted the data, I rebooted in recovery mode and checked that the problems where all disappeared and they actually did. Then I flashed the OpenKirin ROM and the Nano Gapps you told me.
SURPRISE SURPRISE the OpenKirin ROM is pre-rooted with Magisk 15.3 and the installation, this time, went perfectly fine without any trouble! Plus, Magisk updated to the latest version, the 16!
As I promised, I will now update my first post on how to upgrade my mobile phone hoping it will be useful for someone else but first I want to enjoy my brand new phone!
And, of course, I want to thank you for all the support you gave me in these days! You have been really patient and kind! I am really sorry I cannot help you back since (as you have noticed...) I am not much of an expert so all I can give you is my gratitude and thankfulness! THANK YOU 1000 TIMES BOTAR!! :highfive:
You're welcome. Have a nice day! :highfive:

Whats happened with my J5? Need Help guys Sorry (CustomROM)

My device is a J530F (J5 2017).
Im using custom roms for years, but now im deparated with a situation that I don’t understand.
I decided to back to my StockRom (J530FXXS7CTG2_J530FBTU7CTG1_BTU) via Oddin because the CustomRom im using doesn’t have GooglePlayServices (crDroidAndroid-10.0-20210418-j5y17lte-v6.17 flashed with OrangeFox Recovery). PS: This CustomRom is 64Bits, do u think that changed or damaged something in my device?
So, for the 1st time I haved some troubles during the flash stockrom but with few tryes I solved.
When Im back to my StockRom, im surprised to see that my CTS Profile is false and GooglePlay non-certified device. (I think is not normal)…
I rooted the device with magisk for solve this problem and in fact, I solved the Cts Profile but Google Play keeps say that non-certified device. (I searched for Netflix on google play and appear to me so its fine…)
My next step was Reboot in Recovery to flash custom rom. I turn off and turn on with Power, Volume+ and HomeButton. Recovery don’t appear and hes reboot to system mod… So I opened magisk and click Reboot to Recovery but hes turn off and reboot in system mod again… (wtf? -.-‘).
So I have to flashed the TWRP throw Oddin (again) to reboot to recovery. In TWRP I Wiped (Dalvik/Art Cache; System; Data; Internet Storage; Cache) and swipe. Next step was flash new CustomRom (PROMETHEUS_V3_G610X_ARM64 based on A730FXXU6CSJ2)… After flash, when phone rebooted hes show SAMSUNG GALAXY J5 LOGO and then Black Screen (No Samsung Logo) and do not do nothing. (I waited 45min… was the Binary that cause the error??... Was because is 64bits rom? IDK)…
So I repeat all process, go into Download Mode, flashed StockRom, rooted again and flash another CustomRom (PrometheusOneUI V2.0 based on A600FNXXU3BSC5 by Ananjaser1211 @xda-developers That im sure that works on my device because I used during like 1 year). After flash and reboot, the device turn on with Samsung Galaxy J5 and black screen again.
So in conclusion, I cant install custom roms now and don’t know why… somebody can help me?? I don’t tried the same process with OrangeFox twrp because don’t feel that make different but whos know…
Sorry for the long text and bad English, but I did my best for sure…

lineage 17 on samsung galaxy a20e

there are some instructions how to install twrp or lineage on nnthe samsung galaxy a20e. it took me a while to manage it, for one part because it seems sometime i did not do everything exactly like it was described (old fault of mine...) sometimes i found some explication in another instruction.
this is why i post my experiences, to encourage those who also struggle with problems, don't hesitate, sometimes it only takes a bit longer, but also because some things i still don't understand, maybe somebody can explain me what happened..
naturally, firsty of all i first had to install twrp. so i searched for instructions and found some, including liks to download the twrp.tar for my model. some of them i was able to flash by odin, but when i then restarted the phone it only showed a black screen with some pink in the middle, with some fantasy i could read a slight samsung or samsung a20 in it. this happened when i tried to restart in recovery to flas disable-dm-verity, also when i tried to restart direct to system. with all the attempts i got very experienced in flashin back stock rom...
then i found a working recover after restart to recovery i got my twrp screen and was able to flash the no-dm-verity or magisk.
so next i tried to flash the lineage (unofficial lineage 17.zip) but always got the message invalid zip format. tried to unzip and zip again but no way. so i thought i might get lucky with adb sideload, entered the twrp advanced and clicked adb sideload, the screen told me starting adb sideload but the phone could not be detected by the computer. the computer detected it when switched on or in fastboot, so it seems the sideload did not really start.
so i searched the interenet for roms because i really wanted to get rid of google and a million of apps in the stock that i don't need. i found the links to andyyans gsi and several other zips.
as i was not used to the gsi installation i thought i better stick on what i know and tried to install another zip. but most of the time i got the invalid zip message or the zip is for another phone although i downloaded it for the a20e. but then twrp accepted the crdroid.zip (eureka) i downloaded, i was very happy, after the instalation was finished i restarted the phone and the screen went black, turned off and it seemed not pressing to download, to recovery or to start changed anything. i also tried with pressing vol up, vol down and conecting with computer but also no downloadmode started. so i pressed very long always several buttons and after a while the phone vibrated by pressing long vol down and power, but no screen. after it vibrated sometimes like this i turned to vol up and power, it vibrated again and finally twrp started. although the phopne was fully charged when i started the process, it now had only 8% battery.
so i charged the phone again, flashed the stock rom and twrp to try again to find a solution. at this time i also found an instruction that explained why after flashing twrp the system can't recognize the folders (downloads, music... ) and only gives them combinations of letters and ciffers, i have to decrypt it in twrp, wipe, format data, yes and this problem is solved. i don't know it happens always and who made the instructions to flash twrp thought this is common knowledge but in the first innstructions i read it was not mentioned.
i tried again to flash zips and now got a funny eroor message from twrp, unable to zip, this zip is for a20 but this phone is a a10. i tried another zip, the installation started and in the text i could see that it was for a10... so somehow twrp was sure to live on na a10, how could this be??? i thought maybe the twrp was for the a10 (it was a 3.4.x), so i again downloaded a tar directly from the page of twrp for the a20. but when flashed this twrp (3.5.x) and tried to restart to recovery (or to system) the phone was still in downloadmode and refused the custom rom. i had to flash back to stock, then flash again the twrp3.4 that thought my device is a a10, then i could flash the new twrp3.5 i was sure it was from the original site and for my device. i don't know the 3.4 was patched, i got the downloadlink from one how-to-site, but i did not read anything that it was patched...
but after testing all the zips that did not work, and also with the new twrp i was not able to sideload i decided it is time to learn how to handle the xz. so i extracted first the lineage 18, installed it by clicking install image (after wiping) but again the phone turned black and i had to press a while to get twrp restarted and the battery again was nearly down.
the same process worked with the lineage 17, so this is what is now innstalled. both where the correct ab versions, i checked before with treble info what version i need.
so, can anybody explain me
-what happened with my battery when the phone turned to apparently death?
-why could twrp think my phone is a a10, would a twrp for a10 work on my phone?
-is it possible that the sideload feature does not work on this phone?
¡¡¡and many thanks to all those who upload roms and instructions so people like me can make their phones a bit more like they want them!!!
The first time I flashed my A20e (SM-A202F) had the same problems with finding the right TWRP. I cannot answer your questions, but I can tell you what I do.
Beforhand: unloock the bootloader. Upgrade to the latest Samsung firmware. Download AndyYan's 18.1 LineageOS GSI arm64_bvS. Thought arm64_bvS-vndklite can work as well, I found that bvS has less bugs.
After installing the Samsung drivers and the adb stuff on a PC with Windows, I install Odin and flash with Odin the attached TWRP (AP), while phone is in Download mode.
I then go to recovery (TWRP) and if the folders and files are encrypted, I format, then yes. I wipe 4 things: dalvik, catche, system and data.
I then move the GSI image file inside the zip (not the zip) by drag and drop on my PC. Then in TWRP I click install, select image, not zip, select system and flash. Then I reboot to system.
I never had any problems with this installation process. The bvS has a bug with the Lineage music app, but simply install a local music app, such as Musicolet or AIMP from the Aurora Store (from F-droid).
On the camera side I haven't seen any app that significantly improves photo quality. My recommendation would be FreeDcam from F-droid. Use it on special occasions, as it tends to heat the phone.
