OK, yesterday I ****ed up really bad. I have a Sprint Galaxy S4 (SPH-L720T)
My phone was acting slow, so I factory reset it and cleared the cache partition.
Then I reflashed the custom ROM I had on it before the factory reset.
ODIN said it was a success and the phone automatically rebooted.
Except this time, it stayed stuck on the yellow "Sprint Spark" screen.
I tried to go into recovery mode (I have ClockWorkMod) and the phone shuts off as soon as I turn it on into recovery mode.
I have reflashed the root and CWM successfully, but no matter what I do, it just won't go into recovery mode or get past the "Sprint Spark" screen.
On top of that, my internet speed is approximately 150 Kb/s, so there is no ****ing way I can download another ROM.
Every time I try, the download will complete prematurely, and not download the whole file, or it will get about 80% through and say "unexpected network error".
I have the latest version of Google Chrome on my Windows 8.1 Lenovo desktop.
Let me know if I missed any information, and please please please help me.
This phone is my daily user and I need it to be working.
My S7 edge had been acting weirdly for a few weeks, things like random restarts once a few days so I didn't pay much attention and over excessively heating up to 50/55 degrees (I usually checked the temperature through CPU_Z), and just a few hours ago I ran into problems like the phone restarting on its own, never getting past the samsung logo on boot, so I did the normal thing everyone else would do and just factory reset the device through recovery mode, a point to add here the device took an absolute age to load into recovery mode, this wasn't a case of bad key combination or anything like that, the device would load this the dmverity tree hash verification thing and sit there for a good 2-3 mins which is unusual, same thing happens with factory reset takes an absolute age and comes back with the following text-:
"E: format_volume: make ext4 failed on /dev/block/platform/155a0000.ufs/by-name/USERDATA with 1(I/O error)
-- Set Factory Reset done...
Data wipe failed."
booting up the device in this state would show up with an error "Device storage corrupt" with a " reset device" button in the bottom of the screen which didn't respond to any touches which was weird as well because holding the power button and then selecting the power off option worked with no issues so it wasn't an issue with the touchscreen.
searching for a solution on google led me to flash a official firmware that I downloaded from updato, just a heads up my device has never been tampered with or had any kind of software modifications this includes flashing any roms or even official firmwares before, so I download the firmware and flashed it as usual this is the firmware that I flashed through odin 3.12.3 firmware version was G935FOJV1DQAV also my device model is SM-G935FD while the firmware I flashed was for SM-G935F but this shouldn't be an issue because when I usually got updates over the air on the device they would be for SM-G935F so if there were any issues with this they should have popped up a long time ago, so everything went smoothly and the phone booted up again as usual, did the initial setup and adding accounts, recovery everything, hooked up the charger and left the phone to download all the necessary stuff through samsung and google cloud recovery, comeback after a few minutes to find that the device just wouldn't respond to the power button or the home button to wake the device up but the led on the phone was flashing in blue color which means I did receive some notifications, so I hard reset the phone by holding down power+volume down key, same issues pop up like before the firmware I flashed getting stuck on the boot samsung logo, went back to recovery to do another factory reset again it keeps freezing on the dm-verity tree hash thing, but this time the factory reset happens properly with no errors, but the device doesn't boot up at all, gets stuck on the samsung logo and the led on top starts flashing in several different colors, just like when you boot up a brand new S7 edge.
As a last ditch effort I try initializing the device through smart switch, everything goes normally but when the flashing process starts it gets stuck on 7% indefinitely, tried everything else but to no avail, tried flashing through odin again but it gets stuck on the same point as smart switch, tried installing the firmware in parts through odin again gets stuck on the same point when flashing AP but other parts get installed without any problems, download mode boots up fine, recovery mode now boots up very slowly with a dm-verity error "E:failed to mount / system (invalid argument).
I have 1 month warranty left on my S7 edge from where I purchased it, I want to send it back for a refund or a replacement but the only thing thats kind of worrying me is that in download mode the knox switch hasn't been tripped still shows 0 (0*000), but shows system status as custom, will this effect my warranty claim if they check my device?

Having the same issue. anyone help? did you manage to solve this issue?
(Moved from general discussion)
Hey all,
I've run into a bit of a pickle..
I replaced the screen on my S8 (SM-G950U) and after booting, it immediately gives 'System UI isn't responding' and/or 'Process system isn't responding'.
Shortly after (1-3 minutes) the phone will reboot. The errors may appear 1-2 more times before rebooting.
A bit of info:
Model: SM-G950U
OS: G950USQU4CRE9
Steps taken:
Clearing cache does nothing.
Factory reset via recovery mode has no change.
Flashing stock ROM (same version) with ODIN does nothing either.
Before restoring I was able to go in and see the RAM was reporting what I assume is normal (~30% usage)
Also the front camera was no longer working, but I've replaced that as well and haven't had the phone on for long enough to get through the initial setup to test.
Anyone have a potential solution / suggestion? Any and all help is appreciated. Thanks!
Edit:
It might also be worth noting that the shutdowns only happen after booting. There's no issue when entering recovery / download mode.
Havr you tried safe mode?
I know this is an old thread but hoping to get some guidance. I am facing the exact same issue on my at&t s8+ snapdragon as mentioned above. The device is unrooted and was with stock oreo rom. suddenly started showing either "system iu isn't responding" or "process system isn't responding". Later the device started hanging and kept restarting. It restarts from samsung logo instead of the device model name unless force restarted. This cycle keeps happening. I am able to access download mode and recovery without any problem. recovery initially shows "installing update" followed by "no command" but then works normally. The device doesn't power off even from recovery, it keeps rebooting. I have tried (1) cache wipe (2) factory reset from recovery (3) safe mode (4) installed stock rom without problem (5) installed latest stock s8+ unlocked xas pie rom without problem (6) installed latest stock s8+ sprint version pie rom without problem but i am unable to even end the initial device setup as the device keeps hanging with these errors and restarts. Any ideas would be appreciated.
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
Hi guys!
I've read tons of threads and guides on Google but nothing helped me to bring to life my Samsung Galaxy S8 Plus. After hours and hours of test and probes I surrender!
Basically I was using normally my phone and suddenly has power off and showing the Samsung Galaxy Logo continuously. I've force reboot it with vol down+pwr button and after some minutes restart normally again. After 5min again the boot loop and stuck there. Tried again to power it off but didn't work so I thought was the battery (because is 3yrs old with heavy use and months ago I had the screen flickering and a battery drain to zero). I opened the phone, unplug the battery and the power button (because I thought was the power button stucked as on my father phone). So after mounted all the stuff in their place I tried to boot it and suddenly start to work again! I've backup all my things rapidly but again power off by himself and this is the last time I see it working.
So I tried to empty the cache entering in the recovery but it was useless so the only way seems flashing the original FW with Odin. Downloaded the right one with Frija, upload the rights files in Odin (Home_csc because I don't want to lose my internal memory stuff) and the phone automatically reboots, pass the Samsung logo and go in Upgrading mode with the blue android screen and a % increasing. After that by himself power off and nothing happen.
I read some stuff about my possibilities to recover it without losing data but a lot of tutorial talk about entering in recovery but I cannot do it! Simply does not go in recovery with vol_up+bixby+pwr_button even after force shutdown it with vol_down+pwr_button or reattach the battery. The only thing I'm allowed to do is put it in Download Mode to be recognized by Odin.
I've tried to launch ADB devices but it is not visible in Download Mode.
I've tried to flash another firmware for the same model (theoretically my one is unbranded italian) but I tried with WIND one because in download mode there is a text "Carried_ID:WIND" but this FW Odin fail to upload it.
I've tried to flash the TWRP with Odin but fails on the phone with error "Custom binary(recovery) blocked by FRP Lock". I've searched how to unlock it but without have access to recovery or phone settings seems impossible. And this phone has also OEM Lock.
I've tried again to flash the FW but the only difference than before was the blue android robot with stucked text "Installing system update", "Erasing" , "yellow advice notice" and finally a green screen with "An error has occurred while updating the device software.Use the Emergency recovery function in the Smart Switch PC Software". And yes, I already tried with Smart Switch but the program does not detect the phone.
I've also tried to flash the original recovery but nothing change.
Seems that my devices is bricked or a kind of boot loop.
In my situation there is something that I can do to recover the internal memory data? I don't tried to flash the FW with CSC file because I don't want to erase all the data.
My Galaxy was original since the purchasing, no root or flashed a FW, only OTA updates.
I've attached a photo with the stuff that appear in Download mode.
