A20e (SM-A202F) stuck in download mode - error validating footer - Samsung Galaxy A20 Questions & Answers

Hello, i hope someone can help me. My goal was to install lineageos on the A20e. So i unlocked the bootloader succesfully. Then i wanted to install TWRP. I used heimdall for flashing (with: heimdall flash --recovery twrp.img). The process ended without any errors. But since this point the phone stuck in download mode. When i restart the phone (volume down + power) the phone runs rapidly into the download mode. On the top left corner it show an error message (look at the screenshots). I tryed to flash twrp again for two or three times and one times the orange recovery - the results are the same.
I can still reach the phone via heimdall or odin. i have downloades the latest stock rom. So i hope to unbrick the phone - but until now i have no idea how to do. Please tell me, if you know some hints. You can also post if you think its hopeless and there ist no way to unbrick the phone.
Update: I have flashed the stock rom via odin succesfully. now it starts normaly. Do i want to do a next try ;-) ...
Thread can be closed...
Thank U

[Q] i9505 Soft Brick Help - Stuck on Samsung logo (Rooted)

Okay first post on this website.
4.4.2, i9505
So, as i am a compete android n00b, i rooted my s4 with the KingoRoot tool as i thought it was an easy method, later i found out ChainFire made an easy auto root .
After i rooted with the kingo my device would randomly reboot, when i called someone, when i locked my phone and random stages throughout the day.
After some reading online i found the solution was to re-flash my phone to stock fireware. so i downloaded odin, drivers, fireware from sam and tried to re-flash it. however my phone failed after aboot.mbn. I then got the unexpected error saying the phone had to be plugged into kies etc.
I then used "philz_touch_6.07.9-i9300.tar.md5" to get rid of the error message which worked. however the phone still would radnomly restart.
Again i turnrf to the web to find a solution for the radnom booting and found this -

1. The error that give u ODIN is coz you are trying to flash an older firmware that the one you have installed in your device.
2. You have to flash a STOCK recovery. Flash this file via ODIN in PDA/AP (like in the pic 1 attached): HERE.
3. Turn off your device manually when the process finish. Boot it into STOCK RECOVERY by pressing and holding Volume Up, Home and Power.
4. Take a look the CSC (pic 2). "Applied the CSC-code: ............" <- This is your REAL CSC. Turn off your device again manually and boot it into DOWNLOAD MODE by pressing and holding Volume Down, Home and Power.
5. Go to Sammobile and download the LATEST firmware for your device with correct CSC and flash it via ODIN.
6. About KNOX and reboots: Delete all KNOX reminds less "Lib = libknox_encryption.so".
7. Good luck

LG G2 Bootloop Bricked - No recovery or Download mode

Hi guys, I might need some help or a walk through here, I might have bricked my phone. I stump-rooted my phone ( 4.4.2) and installed TWRP Recovery 2.8.1 initially , Installing SuperSU which patched my sdcard and rebooted causing my phone to get stuck in a boot loop giving me no access to download mode, just recovery. From there I tried to install Cynogen mod 12 in TWRP recovery to fix the bootloop but any attempt at flashing gave me an error "error executing updater binary in zip." So I extracted the folders and flashed the 2.7.0 recovery.img which sayed it worked but now my phone is still stuck in boot loop, no download mode and when I try to enter recovery I get stuck in fastboot mode with port change errors. I took some screenshots so it would be easier to help me out. Every time I plug in the USB I get the following errors, the screenshot is from continuous attempts
I have the mini sdk installed and Koush drivers. Device manager does not recognize my phone anymore but it does come up under Fastboot Interface
Any Help would be greatly Appreciated
Because I'm a new member I can't post screenshots so just add an h infront of the links.
Thanks in advance for all your help

Can you please explain how to do that WITHOUT entering download mode?
Maybe LG Flash recognizes your phone and will do the job.
LG Flash does not recognize my phone at all. http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404 Do you think this method will work?

Please help!!!!!!

Today i was trying to install the Android Marshmallow 6.0.1 on my Galaxy S5 Snapdragon via Odin, i downloaded the firmware from Sammobile, i verified that the phone model was exactly the same as named on the firmware, i place the .md5 file in the AP slot and everything was ready to go! (The phone was already plugged and in Bootloader mode, and drivers were up to date) then when finishing the flash Odin FAILS to complete the flash and the phone is left with nothing than the Download mode, i panic and try to access recovery mode but realize that there´s no recovery....I proceed to install the recovery.tar into my phone and it works, i start the phone and Samsung logo comes up, finally it loads and does al the process after you flash a Samsung phone.
Everything works just fine!...except for one thing, THERE´S NO RECOVERY!!!. The phone works perfectly but when i try to enter recovery mode, it sends me to Odin mode as it displays a message saying that failed to boot into recovery.
Please help me i don´t know what to do.
Thanks!
Just flash a custom recovery like twrp or cwm

You need to flash a pit file to complete the install correctly.

My Galaxy S5 appears to be unflashable/unrootable, any advice?

Hi,
I recently got me a Galaxy S5 (SM-G900F) and the first thing i wanted to do was installing CM13 as I always do with my new phones. However, when i followed te steps on CM wiki using Heimdall to flash TWRP the blue bar of the downlaod mode increases a small bit, then stops and in the command promt it says something about error with finding PIT. After trying this for three times i decided to go with Odin, which I do prefer anyways.
I tried flashing TWRP , the blue bar is filling to 100% but then on the little screen where Odin usually states FAIL! or PASS! it just says RESET! and my phone is restarting. Shortly after it restarded you can see the RESET! turning to PASS!, but when I tried checking in TWRP is installed, it wasn't. I tried it again and then Odin suddenly says FAIL! After restarting my phone it says "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again". I couldnt even enter download mode anymore till I tried if getting out the battery would work. I could enter download mode again and flashed the same TWRP on my phone again, and aigain it says RESET! but after that my phone worked again. I tried flashing with another version of Odin and TWRP but same thing happened - First run it said RESET!, second run FAIL!.
I thought maybe rooting the device and installing TWRP via their app afterwards could do the trick. So i tried flashing Autoroot with Odin but it made my phone showing a screen with Samsung logo and in the upper left corner something about recovery mode, seemed to be a loop/freeze. So i took out the battery again and flashed TWRP and that solved the problem again. At last I tried rooting by using TowelRoot but it says the service is not available for my device, even though S5 is listed as a supported device.
I really have no idea what to do anymore, would be very grateful if someone could come up with a solution.
BTW: Is it possible to flash CM13 without using custom recovery by using stock recovery?
Greetings

RESET! is basically the same thing as PASS! What version of TWRP are you installing? The keis screen you got is the same as download mode. Why are you using heimdal? your idea to go with Odin was a good one. Anyways, download TWRP 3.0.2 (not 3.0.2-1 or 3.0.2-2 as they are buggy) and flash it in Odin, reboot to recovery and install the ROM you like, of course following its specific install instructions. No, you cant install a custom rom with stock recovery
Thanks for your answer, meanwhile i managed to fix this problem. Had to flash the latest Firmware because twrp (could just install the oldest version otherwise I had no option to boot into recovery at all) said no OS installed. After rooting via Odin worked like it's supposed to.
Why did I use Heimdall? Because I wanted to stick to CM-wikis instruction and they used Heimdall.

Possibly Dead Device? [P8/P9 Lite (2017)][PRA-LX1]

Urgent help needed as I'm leaving the country at the end of the week o any help is appreciated!
Just successfully rooted my device:
Black, Unlocked, PRA-LX1, UK, Dual SIM
After doing so successfully, I attempted to flash LineageOS from the following link:
https://forum.xda-developers.com/p8lite/p8-lite-2017-development/rom-lineageos-15-1-hi6250-devices-t3811583
Although when I completed Step 6 on the Installation guide and rebooted the phone, I started seeing the message:
------------------
ERROR MODE
Attention!
Please update system again
(Green Android picture)
Error!
Func NO : 11 (recovery image)
Error NO : 2 (load failed!)
------------------
Despite this, I didn't receive a box with my phone due to being second hand, and I didn't see the model number on the receipt as it was from a reselling store. I didn't remember to note down the specific model number
It'd be extremely helpful if someone could possibly help just from the device description above as I'm not sure if it's safe for me to just attempt to flash every stock rom for every other LX1 device out there.
---------------------------------------------------------------
Update:
To restore this, I connected via fastboot with a working USB & flashed an original stock recovery in the video found here
(Just in case their download link ever goes down, I have uploaded the same copy to my MEGA, found here)
The recovery installed fine when using the command
fastboot flash recovery oeminfo.img
Click to expand...
Click to collapse
Whenever trying to flash any other recovery such as twrp before this fastboot stuck on a loading icon.
The stock recovery seems to be downloading the original firmware, too.
PRA-LX1C432B202 is presumably the model.
Both the bootloader and FRA were unlocked when everything else was inaccessible.
Looks like the custom ROM's recovery that you've flashed is not compatible with PRA-LX1. Try to flash stock recovery. If not working, then flash stock firmware.
Thanks @Botar230!
I didn't see your comment until just now after deciding to edit this post since I've gotten a step closer to restoring my device.
Your solution was the method I used although I didn't know my phone model, so I found a random solution which just worked for my device, and the eRecovery seems to be downloading the stock firmware anyways. Thanks again
Before flashing this lineage os you should update to EMUI8 to get treble support, i suppose you was running EMUI5, hence the error mode.
