Hi everyone, I recently started playing around with my old samsung a20e, and I'm stuck at a point where I don't have android and the phone goes into loops whenever I want to reset it. Normally there is a black (backlit) screen. Previously I tried to install twrp and it succeeded, then using twrp, I installed makisk. After reboot it shows black screen and after a few minutes it resets itself showing samsung screen. (reboot > samsung logo warning > blackscreen > again after a few minutes / power + vol-). I wanted to install linux as a hobby. While writing this post, I noticed something else. I leave the videos. And the twrp folder is gone ;(
[edit] If you have guides for writing bootloaders for phones, I will gladly accept it, because I can program in NASM x32 and I can learn to program phones for fun.

Hi, I have a Samsung Galaxy Note 4 SM-910C which I have rooted after flashing a stock Samsung rom. If I recall correctly, I flashed a stock android 4 rom trough ODIN, did it a CF-Auto-Root and eventually updated android 5 through wifi (OTA). SuperSU was installed.
I have attempted to do a native full-disk encryption trough the default Security menu; the phone went into a black screen with a green outline android robot in the center, with no progress bar or text of any kind (I found the image online, but can't post it due to account lack of privilege) . It has been on this same screen for over 8 hours now.
The device was NOT in USB-debugging mode.
What are your suggestions? Should I try some kind of reset? Is it possible the process will resume and is taking so long due to the amount of files? Or I shouldn't expect it to work since I tried encrypting a rooted device?
I'm not worried about any files in it, but I'd like to make sure to be able to recover the phone without bricking it. I'll be leaving the phone plugged to the outlet and untouched for the foreseeable future...
Thank you very much.
UPDATE: I powered off the device (had to remove the battery) and when turned it on again was met with the "Encryption unsuccessful" screen. Then I turned it off and went into recovery mode by pressing and holding POWER+VOLUME UP+HOME. Even tough it displayed a warning - dm-verity verification failed - I chose wipe/factory reset and then rebooted the system and it seems to have worked fine. After the start splash screen and a notification that is was installing applications (bloatware), it brought me the Welcome to Samsung Galaxy configuration wizard.
Hi,
I have a Note 4 t-mobile that is "brick" right now. and I hope if anyone offer assistance.
It is running Android 6. Ever since the last upgrade the phone would freeze and reboot on its own. I fixed that problem by installing Wake Lock. After that it would still experience sluggish at time but the phone is still very much usable.
Lately, after watching a bit of streaming video the phone would slow down so much that a reboot is needed. But yesterday my last reboot turned my phone into a brick. After that reboot the phone rebooted itself to the download mode. So I took the battery out, waited for a few minutes and put the battery back in and started the phone. Instead of booting normally the phone displayed the message including "set warranty bit: recovery" and then followed by the flashing TWRP splash screen. By "flashing TWRP splash screen" I mean the TWRP splash screen ( with the TEAMWIN logo) would be shown on the screen for a second, then the screen black out for a couple of seconds, then the splash screen is back on for a second, and the screen black out for a couple of seconds, etc, and never successfully boot into TWRP recovery. I had left the flashing splash screen overnight and nothing changed. Connect the phone to my pc via usb and fastboot wouldn't recognize my phone when phone was flashing the TWRP splash screen. So I tried to flash TWRP again by starting my phone in download mode "volume down + power". When I connected my phone to my pc Odin recognized my phone. But when I tried to flash a custom recovery (TWRP or CWM) it seems the download started but never finished (on the phone I could see the progress bar started but never progress further).
Any suggestions would be greatly appreciated1
Additonal info
I just wanted to add that my phone is still running the stock ROM.
Problem solved
Problem solved. Once I used a different cable and the download process actually worked and I was able to flash stock ROM using Odin.
My wife's S7 is only booting to the verizon logo (with the little colored circles moving below). Long story short:
1) I was trying to back up her pictures to my PC and all of them disappeared from her phone when I drug them to my PC (6 months of pics). Not sure how that happened.
2) In my panic, I downloaded an application called DR. Fone which professed to be able to get the pics back.
3) After installing the app and connecting the phone, I started the recovery process, which rebooted the phone to a "downloading" screen and then booted to the Verizon logo I have been trapped on ever since.
I have tried powering off, rebooting, clearing the cache from recovery to no avail. I have a feeling that this app altered the bootloader or firmware and now I'm stuck.
Booting into recovery ends up with a "No Command" error. I can get into the Android Recovery menu from there ... but I don't want to wipe it just yet.
Any ideas what could be keeping me stuck on that screen?
Pleeeeaaaaasseee help!
Install this rom, connect to your computer with the verizon upgrade assistant running after the rom is installed. The verizon upgrade assistant should see the phone and you can update it from there.
Hi Guys
I used Odin to reflash my Galaxy S10+ dual sim (duos) as it was experiencing some slowness. I used the Singapore firmware as it uses the same "G975FXXU1ASBA" model name.
The process completed successfully but when the phone boots, it gets past the Samsung logo screen and then gets stuck on a blank black screen with "Starting Android..." showing in the middle. I can swipe down from the top to show the toolbar, but it is limited in what I can select from it and the phone doesn't get to the point where the home screen boots.
I'm guessing this could be an app optimization process but after 4 hours, it was still on this screen.
I've tried re-flashing (redownloading the firmware files), clearing the cache and rebooting the phone.
Does anyone have any ideas?
In case you do want to start clean anyway, have you tried doing a reset in the recovery menu (where you are wiping the cache)? This will wipe all data.
I may have to try the full wipe, which is something I wanted to avoid but seems I have no choice.
Hopefully that at least solves the problem.
I have the same problem but I cannot get it to boot into recovery or download mode. I was flashing Magisk at the time. Odin said it worked but now it wont pass the initial stating android... Odin detects the phone but can talk to it. ADB does not even detect the phone. Phone power and reset come on. if i hold both volume the assistant comes on and if i hold bixby the safemode tag appears in the bottom corner but it still wont boot past Starting Android or boot into download mode
Long story short, I am trying to help my brother recover his photos from his s7 edge. The phone apparently glitched when auto updating, and now will not boot up. I can get it into recovery mode and downloader mode, but that's about it. i have tried loading G935AUCS9CSB1_ATT9CSB1 from Odin3b. All seems to go well and completes, but after what appears to be the install process, the phone starts booting up, gets all the way to the att globe logo, then the phone goes in to a reboot loop, over and over never getting past the Galaxy S7 edge splash screen before rebooting. It eventually shuts off if left alone. If I try to turn it on, it goes to a black screen, RECOVERY BOOTING appears in the top left in blue letters, and then proceeds to try and install update again, but fails to a screen that says no command. Also tried installing firmware from SD card. Loaded the Zip file on the card, but received an error about a bad signature.
I'm a novice at this and have spent 15+ hours trying to restore the firmware to working order, but at this point all my brother cares about is getting his photos off the phone (his wife died recently and he wants all their pics). If anyone knows what I'm missing in getting the phone to work correctly, please let me know. Otherwise, looking for some type of way to just be able to retrieve the photos.
