Hello all,
I've searched and found some things, but nothing that matches my problem.
HTC Kaiser, branded Swisscom. HardSPL, I don't remember the version. Trying to get to tricolor screen, no key combo works. Camera+reset w/stylus, camera+power, even the two soft keys to reinstall the rom in memory.
After pulling the battery (and waiting more than 5 minutes) and inserting again, pushing the power button turns on the green LED, but goes no further, even after waiting up to 10 minutes. Pulling the battery, then plugging in the USB charger (without presses the power button) will flash a white screen after 7 seconds, then a pause of another 10 seconds, then the phone boots in to Android (again, without pushing the power button, just plugging in the USB cable.
Once in Android, everything works (except the factory reset, it just hangs forever). I need to install WM 6.5 ROM.
Tried the KAISDIAG.NBH and the 329 HardSPL recovery, but no reaction and still can't get to the tricolor.
One last piece of information, when I plug in the USB data cable, the phone flashes the "USB connected" message, and then repeatedly flashes it again every 3 seconds. The computer makes the USB connected sound, but no communication and the KaiserCustomRUU.exe can't see the phone.
Any suggestions to get to the tricolor? It unusual to turn on the phone by just plugging in the USB cable.
Thank you and great work.
Try power+camera+stylus pressing the reset.
A while back the charging behaviour was changed, so that now plugging in a charger, or usb, boots the phone, ( previously we could not charge if it was switched off).
Your problem of `losing` the bootloader has been seen before, but is rare, and seems to have no definite cause, the last time I remember seeing it turned out to be a faulty camera button.

Thanks and one more question
Thanks Zenity.
I'll continue working on it. One quick question, is there a command in Android to force a hard reset or to the boot loader?
Camera Button
Ok, after searching more (due to Zenity's suggestion) and reading other threads, I don't think it's a faulty (Fawlty?) camera button.
Somehow, the phone takes along time to boot, and must use some info from the bootloader, as it loads Android.
But all attempts to get into the bootloader fail. I can't establish communication by USB, but I think I will focus my efforts there. I've pushed and help all the buttons in different combinations for too long.
I'll let you know, and thanks again!
Ok, done some research into way to detect that the camera button is functioning, ( since this button is vital in getting the bootloader), no luck yet, but research continues, looking at remapping the camera button using atools, just so i can get a response of some sort, ( normally the camera button does nothing in android, it's unmapped).
Edit: nope, atools won't help, won't let me remap the camera button.
Atools-keymapper remap the key only in the android GUI not in kernel so any change doesn't effect directly the kernel.
Yeah, realised that, just thought there might have been an easy way of diagnosing the camera button, to see if it was at least functioning, but if it's not enabled at kernel level then it will be difficult to test without disassembly and getting a meter on it.

Update - Android.process.acore
Hey all, still trying to connect by USB to use the CustomRUU tool. Now when I plug in the USB, I get a repeating 'Process android.process.acore has stopped etc".
when I click force close, it pops up again and again.
Pulled the battery, and rebooted. Now it boots repeatedly, it shows the splash screen, right when it should go to the Android home screen, it reboots.
Any ideas? Thank you!
probable that the FC and subsequent reboot corrupted the data partition, which is known to happen when the device shuts down unexpectedly.
You can try a 'fix permissions', and 'clear dalvik cache', but normally it takes a wipe and re-install of the system, you may get away with not clearing data, but it's often safer to go for the full wipe of system and data.
Hi, yesterday a friend of mine gave me a nexus 5x with the bootloop of the dead issue, I charged the battery 100% and then started to play a little bit. I managed to get into recovery mode and tried a data/cache wipe, the issue was obviously still there, the thing is when I went to recovery mode, one of the options is "Apply Update from ADB". I went into that mode by mistake, withouth having the phone connected to the PC and now it won't start, not even with the Recovery mode command (voulme+power key). Is there a way to reactivate the recovery mode? The phone is unresponsive to any key combination. Thanks!
@nemesys660: to be sure, Power+VolUp doesn't work. Power+VolDown offers the base menu of bootloader. If you cannot start this way: does system boot (sometimes)?
I searched and didn't see anything that relates to my specific problem.
I have a 1952-4 that I rooted per instructions on here (Magisk). I dropped it and broke the screen about 9 months ago and just fixed it today...and I can't remember my pattern. I'm up to 50 tries, so now I have to wait 120 seconds before it lets me try the next one.
Since the root process requires you to reboot recovery for root, doing that just sends it to the normal lock screen. When I hit Vol Down/Power, my options on the bootloader screen are:
-Start
-Restart Bootloader
-Recovery Mode (restarts it, sends to lockscreen)
-Power Off
-Factory Mode (restarts, sends to lockscreen)
-Barcodes
-BP Tools (restarts, back to lockscreen)
-QCOM (restarts, back to lockscreen)
-Bootloader Logs
-Switch Tools Mode (enables/disables "Tool Mode Config" option on the bootloader screen)
My computer beeps the "something USB has been plugged in" chime when I connect it, but it doesn't pull up in File Explorer (unless it's off, but just shows that a USB drive has been connected but won't pull up anything when I click on it), nor can I connect through ADB. It's not a cable/USB port issue either as ADB finds my Note 8 when I plug it in and check via "adb devices."
Can't wipe it via Find my Phone either because it's been 270 days since my account pinged the phone, so it just shows up as "Android" device.
Any suggestions on how to either get my computer/ADB to recognize it (with root) so I can just delete the lock database, or how I can factory reset it? Am I forgetting a reboot option?
Thanks in advance.

Window 10?
Yeah. It should remember this phone, since I used this computer to root it when I first got it a year and a half ago.
I used a different cable and got it to pick up the phone (as an unknown device) in Windows but NOT ADB, and the phone to realize it was connected (see last line on phone screen) but they're not talking.
If I boot it all the way up, either regular or recovery (root), it doesn't show at all on my computer.
Like I said, I'd be fine with wiping it, but can't even get to that option.
Install the moto drivers. If that doesn't work then make sure your using a usb2 port and not a usb3 port as its a known issue with moto phones.
I just ordered a new OEM cable.
Also ordered an OTG cable to see if I can force it to startup into a different mode that'll allow me to do something with it.
I'll update this thread once I'm able to test them out.
I got a new cable. My USB ports are not labeled, and my Moto drivers reinstalled.
After rebooting to the recovery screen, I plugged it in and apparently I have fastboot. I checked the bootloader logs and it says:
AP Fastboot Flash Mode (Secure)
Fastboot Reason: Volume down key pressed
USB connected
Windows doesn't pick up anything connected by USB. I can't restart to get root because then adb doesn't pick up the phone either because of the screenlock preventing me from hitting ok to trust my computer.
I'm asking the following because I can't find answers: Can you delete the screen lock file with the only bridge being fastboot, not adb. How can I do a factory reset if rebooting to recovery is our normal way of turnin gon the device with root access? Or would reflashing something work?
command line commands are a perishable skill and it's been a couple years since I did this stuff.
Thanks in advance.
To recap, I either need to be able to get into the directory to delete the pattern lock, or factory reset the phone.
I've tried the pattern lock 79 times, which means I have to wait 300+ seconds between tries. I think an error is causing that though.
Fastboot is my only option at this point as far as using commands goes. Rebooting recovery just reboots it with root permissions, but neither adb or Windows 10 picks it up. Using a brand new factory cord and tried every USB port on my computer, even the USB-C to USB-C. But I can't find anywhere that shows how to get into the directory using fastboot.
In Device Manager, I've been getting an error with Android ADB Interface (The device cannot start; Code 10). I uninstalled, reinstalled various drivers, killed adb.exe, etc., Still happening.
HOWEVER, Motorola ADB Interface is working just fine and goes away when I unplug my phone, returns when I plug it in. Only when it's in recovery/fastboot mode though.
I got into Safe Mode, but computer won't pick it up.
I can't get into Field Test Mode. I did reboot it into something else. I don't know what, but the screen was off and the home button was illuminated. EDL mode? I don't know. Neither my computer or adb read that anything was attached, and i can't figure out how I did it.
I also tried sideloading some pattern lock removers, but apparently you can't do that in fastboot.
Thoughts?
Just to close this out with a solution: I had forgotten that in order to get to the recovery menu, you have to hold the buttons when you reboot recovery. Didn't realize that until I was rooting my Moto e6.
Factory reset complete. No more pattern lock. Though since I've now tried rooting it 4 times with 4 different images and have not succeeded even though I had root before all this, I wish I could have realized the above and possibly gotten in and deleted the gesture.
Lesson learned.
Hold what buttons? I'm afraid I'm in same spot.

Just found this. Timing is everything apparently.
Press and hold the Volume Down and Power buttons simultaneously until the Android Recovery screen appears.
Press the Volume Down button to navigate to Recovery.
With Recovery displayed, press the Power button.
When you see the 'Droid' with 'No Command,' hold Power and tap Volume Up just once and immediately release both buttons.
Scroll to wipe data/factory reset by pressing the Volume Down button
Press the Power button.
Scroll to YES by pressing the Volume Down button.
Press the Power button.
The 'phone will wipe all contents.
Press the Power button.
The 'phone will now reboot to the initial setup screen.
Hello,
my wife got a S21 FE (SM-G990B/DS VD2). Yesterday it started to reboot over and over out of a sudden, showing the samsung logo first, followed by the knox logo, then shutting off and on again. Tried several guides to enter Recovery or Download Mode. The only thing that worked was entering download mode by pressing Vol up, down and power while a USB-Cable is plugged in, but as soon as i press the vol up button to pass the "warning screen", it shows some phone specs for a couple of seconds, shuts off and starts bootlooping again. After some hours, the phone once entered recovery mode when it lied next to me for about an hour. Tried to wipe cache, but just got an error I can't remember right now. Hoped it fixed itself when it made it to recovery and just rebooted to see if it works again, but then it just keept bootlooping again.
Since then I couldn't figure out why it once booted to recovery on it's own nor why I can't force it to enter recovery by pressing vol up + on.
Still hope it's just a faulty update or bug, but feels very much like it's a hardware related issue. Replacing the phone won't be an issue, but I'd really want to save data on the phone as my wife didn't make any backups and really wants to keep the photos.
As I just found guides that included recovery or DL-Mode, which are both no valid options for my case, I'd be thankful for any ideas to fix the phone or at least gain access to files before replacing it.
So.. did anyone come across similar issues and found a solution to revive the phone or are there any "unpopular" ways to recover samsung phones out of this state?
Edit:
Turned off completely overnight, booted once to system, looped again and now it's working like nothing ever happened. Got no clue what caused it or why it is working again. Saved everything for the case it happens again.
Wouldn't trust that device anymore, but my wife wants to keep it.
¯\_(ツ)_/¯
I would just like to reply here and add my own potential fix and also would like confirmation that it would work.
So I have a SM-G996B in a boot loop which returns a 'fs_mgr_mount_all' error. Possible to reboot into recovery mode, cleared cache and restarted bootloader etc with the same boot loop. Powered off and connected to PC for Download mode for ODIN recovery but upon pressing volume up, it then restarts again so Download mode recovery is impossible.
I know however that Developer options and USB debugging was enabled on the device as well as unlocked boot loader. I was able to download the correct original stock OS based on the PDA , CSC and Android version.
I have then installed the latest ADB software on my PC and Samsung USB drivers.
By then rebooting into recovery mode, I have the option of 'Apply update from ADB'. I have then confirmed the device connects using the ADB devices command.
I would like to clarify one thing however. I want to keep the user data at all costs. By using the stock firmware and renaming as update.zip, will it use the HOME_CSC and not the CSC file? If not would it work if I open the zip and remove the CSC before re-zipping to make sure?
Thanks

Similar issue with same phone. In a bootloop after trying to root. None of the button combinations have worked for me, for the past several days.
Tried powering the phone off for the whole night.
When connected to the PC shows phone is in recovery mode via adb (blank screen though).
Want to know how to get into DL-mode, guaranteed.
Got to DL mode by pressing vol up + down + power + usb cable connected in PC and phone. However, couldn't do anything there, but maybe you can
Also, phone is still working and I still have no clue what was the problem and what fixed it.
Hi all,
I've been researching this phone for a while and I thought I'd take a chance on a functioning phone with a PIN lock. The phone turns on just fine but prompts for the pin when fully booted. I've been away from Android for a few years, but I can't seem to get into recovery mode no matter what I try. Vol down + power just boots to safe mode (pin still needed) and vol up either buzzes 3 times and does nothing or doesn't boot at all. Even tried with headphones plugged in USB port.
I was hoping that once in recovery mode I could wipe device or at least execute some ADB commands, but this is proving to be more difficult than expected. Also plugging into PC while on or off does not seem to appear in device manager, and no device is made in Windows. Are there any options here or should I just try to return to seller?
Thanks
try 'fastboot oem unlock' to factory reset device
