"No OS installed" after successful custom ROM flash - Samsung Galaxy A20 Questions & Answers

Hey, I'm trying to flash Lineage OS onto my Galaxy A20e (SM-A202F) and after I flash it from an SD card onto the system image partition, it says [IMAGE FLASH COMPLETED]. When I press reboot system from there, it tells me I have no OS installed. Trying to reboot anyway puts me in a bootloop. To get the phone working I need to flash the stock OS on to the phone.
I've tried a few versions of Lineage for the A20e to no avail. I have rooted the phone with Magisk and wiped the system, data, cache, and Dalvik, with the same result every time. I can't seem to find this problem mentioned anywhere else.
I've been at this for days and would appreciate any suggestions, cheers.

Stuck in bootloop trying to flash 7.1 custom rom

My phone is android 6.0 and I've been using "TruPureXMM 2.9" ever since it first came out. I have a February 1, 2016 android security patch level and my system version is 24.11.18 clark_retus.retus.en.US retus
I had an older version of twrp so I just updated it to the latest one before attempting this ofc...
I tried flashing the latest RR and AICP and both give me boot loops and I always get this one problem where it says
"mount: failed to mount /dev/block/bootdevice/by-name
/modem at /firmware: Device or resource busy"
I'm not sure if this has anything to do with the bootloop though...
Going to recovery after seeing the bootloop I always get the "keep system read only?" prompt where i swipe to allow modification but i usually just restore back to my backup from there... i dont think allowing it and trying to boot again will get rid of the bootloop...
I followed the process of first doing a full wipe with twrp > flash rom > flash gapps > restart system
no idea what i'm doing wrong..

1st - you need twrp 3.x+,
2nd - full wipe - format data, adv.wipe - all without micro sd.
3rd - flash rom, flash gapps(opengapps.org, ≤mini, arm64, 7.1)
Last Rr is for Nougat modem - you are on MM modem.
Flash RR 21.11.2017.

The first 3 steps I've already done that since the beginning
Where can i get the nougat modem/is it possible to update to it? I guess that's the reason every single 7.1 custom rom I tried in the android development section gave me boot loops...
And could you link the 21.11.2017 version of RR? I'm looking at the download links for RR and I dont see one with that exact date
edit-just saw your edit
Custom roms for MM modem works better.
I fully wiped using TWRP, checked everything I possibly could except my micro SD card and I flashed RR-N-v5.8.5-20171121-clark-Final.zip then gapps arm64, 7.1 nano and it's still giving me boot loops. I'm using TWRP 3.2.1-0
im gonna try using gapps arm64 7.1 mini really quick since you said I should use that one and see if it boot loops... - Edit guess I was too optimistic thinking this would fix it
Bugs probably after flashing december RR.
Change twrp to 3.1.x, reboot twrp, change all partitions to ext4 - adv wipes - One by one - cache, system, data, reboot twrp.
Change back to f2fs - only cache & data, wipe all, flash what I wrote.

It doesn`t matter.
Try another custom - LOS f.e.
If bootloop still will be - you should flash full stock.
Last MM for RetUs

I tried crDroidAndroid-7.1.2-20171119-clark-v3.8.3.zip and it still boot loops :\ I also already tried LineageOS and AICP before we started talking
I went back to my backup and it put me in a bootloop which never happened before but changing cache back to ext4 instead of f2fs fixed it..

A little late to chime in and this does not help with your current situation, but here's a little advice. I flash a lot of ROMs (how else am I going to test builds right?). This error happens all the time, BUT if you flash a ROM twice it should not show on the 2nd flash.
So flash order goes:
Wipe/Factory reset
Format data x3 (yes I format my data 3 times for every ROM)
Reboot
Wipe/Factory reset
ROM
ROM again
GAPPS
Wipe caches
Reboot
Do the Initial setup
Reboot before use
OPTIONAL Kernel (if its not already build in)
OPTIONAL Magisk (I never flash Magisk on a clean build but heck I'm expecting a NON boot most of the time anyways)
At this point I would flash the stock Nougat image via fastboot to get the device operational again... Then look at TWRP, root, or custom ROM.

so should I just straight up flash the nougat image via fastboot from your thread here? https://forum.xda-developers.com/moto-x-style/general/xt1575-moto-x-pure-edition-factory-t3704142
i dont need to go back to mm stock or something first? I don't really have much knowledge about this.

Correct... And verify everything is working properly before you flash TWRP, root, or take any OTA update.

Boot TWRP (don't flash it) and make a full back, and I would recommend not talking any OTAs either.
Then knock yourself out... You can always get back to this state if things go badly.

I'm not sure for others but RR - only 5.8.5-04.12 works with N modem.
Did you check/set access points properly?
All customs for N modem(I think) have problems with notification sound, so you can stay at stock.

I'm using t-mobile and I've checked the access points, clicking on the one im using and hitting save doesn't fix it. Always getting a notification telling me to sign in to network. Not sure what else I can do. I'll give it a day since I had this kind of problem before when I switched sim cards and data didn't work until the next day
Edit - just went back to stock and my data doesn't work now either... just going to stay at RR now and hope my data fixes itself because my access point settings for tmobile should be correct since I looked it up on the official website..

ZE552kL (Soft Bricked)

I have bricked my phone the issue I am facing is I don't own and can't afford an SD card to sideload the rom onto my phone is there a 7.0 stock based rom that is flashable via TWRP or? Really need some ideas need to fix this device.
If you have access to TWRP, then plug your phone into your computer and it'll mount your internal sdcard. Copy any Rom you want onto it and flash as normal (remember to wipe cache and dalvik!). If you get the "error 7" output, edit your updater script and do it again. If you get a bootloop after successfully flashing, flash the latest magisk zip (I assume you use root?) or noverity file if not.

I use root and both but when I decided to remove root and was looking at installing another rom it failed now I don't see any twrp flashable roms for my device would you know of any? I tried stock but it can't be flashed from TWRP sadly I have no bootable rom at the moment.
@mastermarkofroms
EVERY Rom that can be flashed through stock recovery can be flashed through TWRP.
....all you need to do is edit the updater script as I said above. Give it a shot
Edit: you softbricked your phone removing root? Just perform a factory reset, you'll lose your personal data but it'll boot. Remember to wipe cache and dalvik.

I have never modified that before what would I need to modify to get it working?
@mastermarkofroms
Open the Rom archive and edit the updater script (/META-INF/com/google/android/updater-script) to remove the first 7 lines (sometimes more or less) of code, so the script starts at "ui_print....." now. Save it, and load it onto your sdcard and flash.

I will give that a shot turns out a factory reset did not start up device so this is my last choice as I can still access recovery
edit: so after modifying the script it did flash without an issue but it still has failed to boot reloading the bootloader.
Flash magisk or the no verify file

Which Rom did you flash?
You performed a factory reset and wiped dalvik and cache after flashing? How long did you wait after rebooting? Usually takes 5-10min on the first boot.
Edit: you flashed the no verity file after flashing the rom today, right?

I tried flashing Unofficial LineageOS 14.1 for ZE552KL by basenode with opengapps it just failed to flash not an error 7 it actually gave me a wrong device error although I know I have the ze552kL model. and since then it don' boot it tries to you see the asus logo and it just restarts again in a boot loop
Flash magisk right now, then wipe cache and dalvik
Go back asus nougat 7.0 -> factory reset -> flash LOS 14.1 -> flash gapps -> done. Flash magisk if you want.
Edit: when you go back asus rom and face bootloop then just flash no-verity file, everything will work like normal .

Did you installed Twrp...if yes then you might want clear cache and restart the phone or you could just reflash the rom or any other custom rom....and if you havn't then i am afraid you will have to lose your data..

yes yes i've installed twrp, i've actually tried formatting my data, clearing dalvik cache (thru twrp) then restarted it but still stuck at loading zenfone logo. i dont care bout my data on phone, just wanna get my phone back to normal.
can u please elaborate bout reflashing rom? i've never done flashing any rom before , stock or custom,
Never done this on my M1 but on my note edge,
When i got a bootloop, i simply reinstall stock rom, or just clean install custom rom

Ok so it's good opportunity to try something new...first you need to download custom rom and gapps package to sd card (always a better option)or internal storage...do the downloads on pc or somewhere else...
1. Wipe cache, dalvik cache, system, vendor, data, internal storage(this one is optional)
2. Mount extsd card
3. Install Rom package...(i personally use xenonhd based on pie) from here https://mirrors.c0urier.net/android...tal/X00T/XenonHD-181007-Experimental-X00T.zip
You can try any other of your choice
4. Install Gapps package from here..http://download2264.mediafire.com/r0vq21tabscg/m1u4llu62bdwyos/BiTGApps-arm64-9.x.x-0.1-unsigned.zip
5. This step is optional if you want root access then flash magisk package from here..https://github.com/topjohnwu/Magisk/releases/download/v17.1/Magisk-v17.1.zip and uninstall package from https://github.com/topjohnwu/Magisk/releases/download/v17.2/Magisk-uninstaller-20180921.zip ......after tge rom boot up install magisk manager from https://github.com/topjohnwu/Magisk/releases/download/manager-v6.0.0/MagiskManager-v6.0.0.apk
6. Reboot to system..first boot up will take 4-5 minutes...ENJOY
so i tried flashing the stock rom but i got an error
Code:
[B] This package is for "ASUS_X00TD" devices; this is a "X00TD"[/B]
i got the rom at asus.com/ph/Phone/ZenFone-Max-Pro-ZB602KL/HelpDesk_BIOS/
i guess i'll try flashing with a custom rom instead?
also a follow up question: is it safe to reboot to recovery with twrp even my phone has no OS installed (already wiped it for flashing a new rom)

Oneplus 5 hardstuck bootloop. Please help me out, I've tried everything!

Firstly, my phone isn't hard-bricked. I'm able to load different versions of the TWRP recovery and access Fastboot without any problems. I'm also pretty comfortable using adb to push, sideload, access fastboot, recovery , etc. so please feel free to throw out any suggestions that might help me resolve my issue. (Note:I'm unable to find the stock recovery on OnePlus's support page anymore, I recall they always had the option to download the stock recovery just below the download option for the stock ROM, so I haven't been able to try sideloading after formatting with the stock recovery.)
My OnePlus 5 was running stock Oreo and I'd been meaning to upgrade to Lineage 16.0 (Pie) or any other Pie ROM really. I booted into TWRP (3.2.3-0 - Oreo firmware) and wiped everything other than USB storage and formatted data too as my previous Oreo installation was encrypted. Then, I downloaded codeworkxx's 9.0.3 firmware for OnePlus 5 and pushed it to my phone using adb. I flashed the firmware successfully, rebooted into Bootloader/fastboot; and flashed the Android Pie version of TWRP recovery ( https://sourceforge.net/projects/cheeseburgerdumplings/files/16.0/cheeseburger/ ) and was able to successfully boot back into the recovery. Since then, I've tried to flash multiple different Pie ROMs (Pixel Experience, Lineage 16.0, stock OOS official build - 9.0.3 , Beta OOS build OpenBeta26) (clean flashing always) but always ended up with a bootloop with the boot animations in all the ROMs. I've even tried flashing them with Magisk-v18.0 but that doesn't help either. I've waited for 15 min with each boot for the different ROM's (ending up in bootloops) and on rebooting back to TWRP, I've always found that irrespective of ROMs, the only folder that's created in Internal Storage is 'obb' and it is an empty folder. I've even tried sideloading OOS 9.0.3 (official build) via TWRP and that still ends up in a bootloop with the obb folder in Internal Storage being the only thing created. Also, flashing the boot.img recovery in the stock ROM zip files leads to a blank screen with a white LED that tries to install Qualcom drivers, so I just reflashed TWRP and am back to where I started.
That pretty much sums up my problem here. Kindly throw suggestions at me to help fix my problem' I've searched the forums but most of the bootloop issues I've found and read are about unsuccessful firmware flashes (not the case with me as I've explained above) or dirty flashes (again, not the case with me as I always cleanflash).
Thanks!
You should be focusing on getting stock OOS back on before trying custom rom. Have you tried rolling back to 5.1.7 Oreo? Sometime it better to go back to square 1 and try again.

I successfully flashed the 5.1.7 firmware and Oreo-TWRP-recovery and was able to install Lineage OS 15.1 and boot it up properly. I'm unable to find a link for previous versions of OOS to test whether or not 5.1.7 would work. Do you know where I can find a link?

So the Lineage 15.1 flash worked fine but OOS 5.1.7 still leaves me with a bootloop and the obb folder as detailed in my first post. I'm unsure as to how to proceed.

Lineage 15.1 (official) boots successfully but without radios working... I tried reflashing Firmware-5.1.7 but that does not help; not sure how to fix this. Could it be a firmware issue with installing Pie ROMs? But then again, OOS Oreo doesn't boot either - still ends up in a bootloop
My only suggestion ...

Lineage 15.1 (official) boots successfully but without radios working... I tried reflashing Firmware-5.1.7 but that does not help; not sure how to fix this. Could it be a firmware issue with installing Pie ROMs? But then again, OOS Oreo doesn't boot either - still ends up in a bootloop

Greetings! I got your private message, but I haven't read it yet. Sorry, very busy today. However, I can make the following suggestion to get your device back into original working order.
Have a look at this link on xda. It's for an unbrick tool, which I've used numerous times with great success.
https://forum.xda-developers.com/oneplus-5/how-to/unbrick-tool-oneplus-5-t3648169
This tool will put your device back into its original condition, with original OOS.
Let me know if it works for you.
Peter

OxygenOS also needs a formatted internal storage, otherwise bootloop will pop up

Definitely! I've always been clean flashing ROMs (Wiping Internal Storage, Data, System, Dalvik Cache, Cache + Wiping/Formatting Data to factory reset ) for each trial!

Wiping system, data, cache, Installing 5.1.4, then magisk, then format internal storage, then boot os should not cause a bootloop
What's your twrp recovery? Did you tried mine?

That's exactly what I'm doing. I've tried using codeworkxx 's versions, blu_spark TWRP versions and yours too!

Thank you for replying!
The tool doesn't detect my device whatsoever - I have system-wide adb & fastboot set up (to use from any folder or path) yet the device is not detected in fastboot mode or recovery mode.
How do you use it?
Thanks!

You need to put your device into MSM Download mode. It's simple. Power off your device. Press and hold the Volume UP key for about 8-10 seconds and, while continuing to hold the Volume UP key, plug in your device to your computer via USB. Open the MSM Tool and press Start.
That's it.
It takes about 3-5 minutes for the tool to complete the unbrick process.

Thank you! I was able to successfully use the unbrick tool to reset to OOS 4.5.8 Nougat. I'm going to try stepping all the way up to Pie now!

[SOLVED] Bootloop since TWRP installation

Hi Everyone,
The first thing I did after flashing TWRP on my RN7 was a BackUp with TWRP of all my partitions. (It was the first time i launched it, so i also saved the Miui Recovery).
Then I tried to boot on the system but I get stucked in the "Redmi by Xiaomi" screen.
I tried to install an AOSPExtended Rom but it didn't worked.
I flashed Orange Fox and retrayed to flash AOSPExtended. It didn't worked either because it was designed for violet and not for Lavander (facepalm).
I tried an Unofficial LineageOS found on XDA, the installation worked but I'm stuck in a bootloop since.
The Redmi by Xiaomi screen starts over and over. I can't even turn off my phone.
I tried to reboot after wiping Cache, System, Vendor, Data and Dalvik (just to see if I would be able to turn it off) but same result.
Do you have any Ideas?
Thanks a lot!
Which rom did you have while taking the first backup?
Wipe System, Data, Cache, then reboot the recovery and then restore the backup of System, Data and Boot. Don't restore recovery. See if this works.

Flash a custom ROM with the latest OrangeFox, then format the data partition (Menu->Manage Partitions->Data->Format data->"yes"), then reboot to system.
Do NOT try to restore your TWRP backups.
I finally tried an other Lineage Os Rom from XDA and it finally worked.
But I don't really know why.
The first one I tried to install was in fact a Potato OS... (You can download it from the same page!)
But still, this ROM was for Lavander too, I don't understand why it didn't worked....
Anyway my phone is OK now! Thanks a lot!

What would happen if I tried to restore my Backup?

What would happen is :crying: Returning to MIUI from a custom ROM is a can of worms. There are instructions here: https://wiki.orangefox.tech/en/guides. But even that is not guaranteed to do the job.

I think that would be a good thing, otherwise, people will stumble upon it, and keep posting.
