Hi,
I've got my good old 9505 I bought right at release on which the Volume UP button (or more likely whatever hardware it's connected to, as the button itself works perfectly normally) has become stuck pressed.
That causes a little problem - I can't enter Download mode anymore (Normal power up enters recovery due to the stuck key, Vol Down cancels Recovery and boots normally).
I had a custom ROM and recovery on it, and in order to send it for repair I obviously want to put it back to stock status, so I have reflashed a stock MI8 image I found using ODIN, using the custom recovery's "Reboot in Download mode" command.
Now the problem is I have bad luck and likely had an incompatible modem, and after booting even with cache/data wiped I have the Samsung keyboard crashing constantly and WiFi won't work.
Of course restoring the stock image wiped my custom recovery, so I can't use the same trick to get back into Download mode and reflash another modem.
I can't use Mobile ODIN or reboot menus with a "Reboot Download" option, as those requires root, but... rooting needs Download mode.
I can connect to Kies, but for my region it unfortunately says the current ROM is already the latest.
Does someone have an idea I didn't think about?
is there a way to reboot to download mode via usb debugging?/adb shell or something like that?
I found something that suggested it, however while I've painfully been able to go enable USB debugging (with the UI that locks and the "Samsung Keyboard has stopped" messages that appear between nearly every tap) adb devices returns nothing. Maybe the same issues cause debugging to fail too...
make sure that all instances of kies are stopped and also try reinstalling the drivers?
OK, found an app called "Kingo Android Root" that works from the PC through adb, and managed to root it again. It took some time to connect, but once it did it went through the procedure OK.
Then I could transfer the apk for "Quick Boot" to the phone through MTP, and its reboot menu worked to reboot in Download mode
Got a new modem flashed, and WiFi is back. The Samsung keyboard is still crashing every 5 secs, but I'll just try reflashing the OS, never know...
now that you can get to download mode, you can just restore everything back to stock? no? should fix any fc's you're getting, unless they are related to the physical fault with the volume up button being stuck?
Yes, it's just a matter of finding the right stock ROM... :\
OK, the MKF ROM for my country I found here works perfectly fine.
Issue closed then, hope this will serve other people who might end up in a similar situation
Now to see how the service center reacts to a stock config but with Knox flag set...
good luck, and don't forget to let us know how you get on with the service centre/knox situation.
Good news, received my S4 after a one week turnaround (shipping included), and it was repaired under warranty even with the Knox bit set and me having dismantled it (thanks Sammy for not putting "warranty void" stickers, pretty much the first manufacturer I see who doesn't!)
Hello i have been freaking out and researching this for hours. (found nothing)
What I did
https://www.youtube.com/watch?v=o9gL_4KNs_Q
I have T-Mobile.
Now when my phone boots up it keeps shutting off. stays on for 1-5 seconds
I then did a factory reset and cleared the cache.
I can some times get it to the home screen and flip back and forth on the different screens then it shuts off. I have seen I have superuser on in the apps but don't get a lot of time to check root before it shuts off.
I do have red text on the Samsung logo screen that says "kernel is not seandroid enforced" (Spelling)
What do I do?
Safe mode also shuts off.
I can get to download mode and recovery mode
I just cant get it to stay on .
Any help would be great thanks.
Additional info
Update more info: When I factory reset. I do get an error failed to mount /preloader (no files or directory) wording might be a bit off but that's about what it says.
does it restart in recovery/download mode?
does it restart when the plug in into a charger?

I guess I should have changed the wording. Its not rebooting it just shuts off.
No It does not restart when I charge it. But it does show the battery image and charges.

me too, if it doesnt reboot while charging means possible battery issue.

Sorry for the miss communication.
Lets try this again.
I can plug the phone in and it charges while its turned off. you know the battery screen.
I can volume up, home and power For down load mode
I can volume down home and power (factory reset, cache delete so on)
I can get ODIN to connect but I cant flash the firmware I found. Maybe its the wrong firmware? Could you point me to what I need?
But when I just turn it on either charging or not it shuts it self off a few seconds later. Seems to happen after a message about auto time and date pops up. And when I say shuts down it just shuts off no like shut down screen or anything.
ok start again, please put all info so it wont be confusing:
what initiate the problem?
did you install a custom rom?
are you rooted?
what phone model are you using?
odin version?
have you tried flashing thru samsung switch? if not, try it

Update:
I just got my phone back from Samsung. On Friday they told be they didn't fix it because it was rooted and said they are mailing it back. Well now I don't have a phone so I Saturday I went and got a new s7 edge from t mobile. Its now Wednesday and I get my phone from Samsung. I open the package all bummed wondering what I am going to do with this phone. I then see the phone is in a small blue draw bag thing I thought it was cool so I open it to look at it and I see my phone light it. The sim card and tray on taped to the back of the phone but my phone is on! I then sat here looking at it waiting for it to reboot. I put my sim card. Then a screen popped up saying reboot? and I click yes . I was so mad at myself but then it restarted and everything was ok. I installed root checker and I have root access. the phone has now been on for the last hour or so. Not sure if it was something Samsung did or taking the sim card out did something.
But now I have a rooted s6 edge plus rooted and a s7 edge. and out like 600 bucks
Best solution, use Samsung's Smart Switch software (download from their site) and restore to factory ROM and kernel (official Samsung version). If it is anything software related, this will definitely fix it.
in case you dont know the steps: open smart switch, connect device (make sure its detected), got to more > emergency software recovery & initialization > Device initialization > type in your exact model name at the bottom > then serial number (make sure you type it correctly > type ok, follow instructions, and let it do its thing .
Try this and let me know how it goes. Good luck.
its kernal issue try to flash a different kernal available for edge+
Hi guys, a friend of mine asked me if i can fix her child's tablet (It is galaxy tab A 10.1'' with LTE T585.
Her problem was that she factory reset it, because her child set a pattern and forgot it. They also dont remember the password, hence FRP problem.
I tried to flash a new Official rom from Sammobile and tried to flash it via AP option, but it got stuck on about 95% at Meta-data/Fota.zip and the screen is flashing somewhat. Upon further reading i understood that i need newer Odin, hence i had to unplug the cable and start over. However, I am unable to access download menu anymore. When i press home power down and lock nothing happens, until i plug the cable in. Then Odin sees it (although the tab says Error occurred bla bla use Smart switch PC software, which does not support the tablet weirdly). But i cant flash anything like that it gets stuck at initializing.
I am open for any suggestions on how to fix this or i might have to end up buying a new tablet for her.
Thank you guys!
PS: Ive been long away from samsungs (since S5 disappointment so im not really into samsung specifics).

Irrespective of whatever state the tablet is in just hold in this order HOME + VOL DOWN + POWER. Hold until the screen goes blank then when you see the Samsung logo release after a few seconds.
Once in DOWNLOAD mode flash using at least odin 3.12
Tried that already but Odin was staying on initializing. Gave it to a phone mechanic and he fixed it now i need to find a way to know which Android version it has and how to bypass the frp.
Hi everyone,
When I tried to restart my Galaxy s8 it entered some kind of hardcore bootloop where I couldn't stop it from looping except by entering the download mode, letting it drain the battery or simply disconnecting the battery. When I exit the download mode it will just continue looping. It is also impossible to enter the recovery menu, which makes things much worse.
I have tried opening the phone and disconnecting everything except power supply (either battery or charger) and screen to see whether some detachable component is failing it (camera, speaker, etc.). But nothing.
I have also tried reinstalling the firmware (BL + CP + AP + HOME_CSC), it installs successfully but it doesn't fix the bootloop. I have also tried two most recent firmware, also without success. Somewhere on the Internet I have found a recommendation to install the firmware from June 2017 which I have tried but it doesn't work anymore because it's not possible to install earlier version of firmware on Samsung phones anymore (since November 2019 I believe).
Now I have started to believe that this could be a motherboard failure but it doesn't really make whole lot of sense because the phone can enter the download mode and reinstall firmware just fine. Or maybe there is a component which can make it able to enter the download mode, but nothing else would work?
Has anyone experienced something like this? How could it be fixed? Any recommendations? Is there any hope?
Edit: The phone has never been rooted, means it is in its original software state (currently on Android Pie with build number G950FXXS8DTC1). Is there any way to install anything on it (custom ROM, TWRP, etc.)?
Come on guys! Please don't tell me that I've tried everything and exhausted all the possibilities...
If there is still warranty on the phone, then send it in for repair. If there isn't, then I would take it to a repair shop and see what they can do about it. It is wierd that you can enter download mode, but can't flash stock firmware. I think it might be a motherboard problem

Unfortunately, there's no warranty and I'm pretty sure no one would repair this kind of failure for a price lower than the price of a used and fully functional Galaxy s8.
Yes, I can enter the download mode and I CAN flash stock firmware, but I can flash only the ones which are newer or the same as the one installed on the phone.
Yes, most probably it's a motherboard failure. In some YouTube videos I have seen people fixing similar issues by replacing the CPU (which I am unable to do by myself). Other suggestion I found on iFixit says that I could soak my motherboard in 99% Isopropyl alcohol and leave it overnight in it (I am going to try this if I get my hands on the alcohol).
BTW: One interesting thing I experienced while flashing the phone without its battery connected is that the phone's screen will go black when you press 'Start' button in Odin, but nevertheless the installation will finish normally and you can track its progress in Odin. At the end you'll need to restart your phone manually.

I have an S8 with a similar issue. I can get to recovery menu but following similar steps to above by flashing combination firmware and still got stuck in bootloop. Subscribing to this thread in case anyone has a fix.
Just wanted to share a video I found. This is exactly how my s8 bootloops: https://youtu.be/gBlIcAJzgVA?t=5
PS: Obviously, the solution explained in the video didn't work for me.
PS2: This issue started by just restarting the phone. Before the restart it was in a perfect state, fully working, never had any hardware issues. Although there were some software issues introduced by an update (October or November 2019 I think) which made my phone need to restart 2 times to fully boot once if I wanted to restart it or turn it on after it was turned off. But those software issues were solved by a latter software update.

Hi!
I used my S7 Edge for a couple of years and now I am afraid it may have died on me. As always, backups of f.e. pictures are not up to date.
During the night, it lay on my Qi charger. When I took it in hand, the screen was extremely dark and stuck in the "loading Lineage" screen. I tried to reboot. It was stuck on the "Samsung Galaxy" screen.
I wanted to boot into recovery and wipe the cache and see if it works again. But I can't boot into recovery mode. No matter if I connect it to a USB cable, the button command does not work.
Switching the device off also isn't possible. The only way to switch it off is disconnecting the battery (I have opened it to do so).
The only thing I can do is booting into download mode (so I know my volume up button works...).
Several times the screen was stuck on the "empty battery" symbol - which did not change no matter how long I had it in the charger. I can't really replicate how I got to the battery screen. I installed another battery just to see if if by some magic this would change something, but nothing changed about my issue. No boot possible and no booting into recovery.
I thought to myself: Well, maybe if I reinstall TWRP I can get into Recovery again. But when I try Odin I get the error message: "there is no PIT partition"
I know you will want additional info:
sadly, I cant' say which version of lineage I had running. I would have to look into my phone - which I can't.
I installed Lineage a couple of years ago, the phone was rooted and had TWRP recovery. I changed my USB port and Audio port several months ago.
But everything was running fine - I did not change or do anything recently. It happened overnight.
Do you have any ideas what I can do? I am brooding for two days now over this issue and I am at the end of the line here.
Did my memory just die on me? Is it an unfixable hardware issue?
Or software-related and potentially salvageable?
thanks in advance for anybody that bothers with my problem.

Hi, try to flash the stock firmware otherwise I really don't know :/
I guess I will lose my data when I install stock firmware, don't I?
What I ask myself is: Is the reason for not being able to boot into recovery that my device always thinks my battery is empty?
Is the fact that I can boot into download mode a sign that my memory and/or motherboard is still intact?

Are you using Lineage OS? If yes, then definitely yes. On my Xiaomi, I couldn't get into fastboot mode or into recovery, I don't know why and somehow I got there, I don't even know how I think I held the power mode for a long time and when the phone turned on I held the volume up button to get into recovery finally succeeded on the umpteenth attempt and from recovery I restarted the phone in fastboot mode and flashed the stock firmware. And yes, being able to boot your phone into fastboot is a good sign. It would be worse if it wasn't possible.
I am still stuck with the problem. I can boot into download mode. I can't find a way to boot into recovery.
Is there anything I can do in download mode?
If I find the lineage version I originally installed on my device, could I install it via ODIN and get my phone back without data loss? I have only ever installed ROMs via TWRP.
Just an idea, but as of now I get the error "could not find PIT partition" anyway while trying to reinstall TWRP.

Yes, you can use download mode to install the firmware via Odin. Look
That means giving up hope for my personal data...
But even if I want to do this, I run into the problem, that I can't install anything due to "could not find PIT partition"...
