[Q] Download mode Samsung Galaxy grand quattro/win 8552

Hello Guys,
I am trying to boot 8552 into download mode but i am not able to enter.
This is what i did so far.
1: made sure USB Debugging is enabled
2: pressed power + volume down + Home till i enter odin, (never entered)
3: press power button till you get vibration and then press power + vol down + home will you see warning.
Above one actually works better then 2nd step. But as soon as i leave any key to press volume up, the cellphone reboots.
I have entered ODIN mode before, but it looks like i am not able to enter it since last samsung update.
Plus the last update unrooted my device
Same problem
Same problem here . I have tried to flash TWRP and bricked my phone. Whenever I've tried to enter download mode it enter into factory mode :crying:

how to boot into recovery mode through pc ?

Hi,
I own galaxy s3 i9000, currently on custom rom. My phone automatically rebooted and got stuck on bootloop. If I am able to enter in recovery mode, i can wipe cache(which may can help to get out of bootloop). But the problem is I am unable to enter into recovery mode because phone's volume up button is not working and my phone auto reboots every time after power off or reinserting battery. Is there any other way to clear cache or enter into recovery mode?
I dont want to flash my stock rom via odin (because i didnt backup my some important apps and msgs), this will be my last option.
sorry for my bad english
The normal way I get my phone into recovery mode from the PC is using ADB and the command: "adb reboot recovery". However, I bet this won't work in your case for one of several possible reasons: depending on when the bootloop occurs in the boot process, the phone may never reach a point where ADB is able to see your phone in the first place; if this is happening after a flashing a new custom ROM, then also it's unlikely that USB debugging is turned and the PC is not yet authorized to connect with it over ADB.
Another thought, could your power button be stuck down? I had a GS3 SCH-I535 several years ago and the power switch went bad on it, it would keep rebooting, shutting down randomly, or I'd be unable to turn on the screen. I had a switch replaced and it was fine after that. I don't think it's normal for the phone to automatically boot up when you reinsert the battery, that's why I bring that up. Maybe you can wiggle the power button a bit and try to unstick it if that's the case.
I tried to remove and stick back the power button again, but still it didnt worked. By the way fixing power button will not help me to get into recovery mode as my phone's volume up button is also not working, and recently I found out that I cant enter into download mode too because when I press respective buttons (volume down + home + power) for download mode, it gives warning msg to click 'volume up' buttton to enter into download mode or 'volume down' to reboot. Therefore again volume up button is required to enter into download mode too. So the only option remained for me is to visit service center and fix the volume up button.

[SOLVED] Getting into Recovery on the Mi Pad 2 [Latte]

So I've been putting custom ROMs on devices for years and I've never had this problem before.
Problem: I can't get into Recovery (TWRP) after I've flashed it but before MIUI restores stock recovery.
I've tried:
1) Holding Vol Up + Power as I hit "fastboot reboot"<Enter> in fastboot
2) Running the power down while in fastboot, giving it a little charge, and then holding Vol Up + Power
3) Locking the bootloader and trying both 1 & 2 again
Result
- Without locking the bootloader I get the "unlocked bootloader" message, have to hit Vol UP and then it boots into System
- With a locked bootloader it ignores my "Vol Up + Power" altogether and just boots into System
For the fun of it I tried Vol Down + Power (to get into fastboot) and had the same problem. Funny thing is if I flash back to stock, VOL UP + POWER gets me into recovery just fine.
Any ideas?

So I figured it.. reading a post in the MIUI forum (XDA won't let me include the link), I found the following:
Turn off your Mi Pad 2, Press power button to turn on Mipad 2, when MI LOGO appeared, immediately Hold down VOL UP and VOL DOWN until you see the yellow line DNX FASTBOOT MODE appears, release the buttons.
Click to expand...
Click to collapse
My problem was I was pressing both buttons at the same time as I do with my other devices. Solution is 1) Press power button, 2) wait for MI logo to appear in the center of the screen, 3) Press VOL UP. Voila!

[Q] Bootlooped, can't access download or recovery

Hello,
as I wrote in this (now locked) thread, I installed Superior OS and got stuck in bootloop. I get "Galaxy S9+" screen followed by system bootanimation, which repeats itself indefinitely. It doesn't restart by itself, it just boots endlessly.
The problem here is that I can't access recovery or even download mode. I tried to restart (power + volume down) and then quickly press combination to access recovery or download mode. No luck. I couldn't even turn the damn phone off. I just kept restarting.
So I let it drain the battery hoping I could then power the phone on with correct key combination. I tried holding bixby button + volume down while inserting USB. It just started booting up to system with boot animation. I tried holding bixby + volume up, or even power + bixby + volume down. No luck either.
I got correct USB drivers installed, as I flashed the phone with Odin in the past. Odin recognizes phone while it sits on boot animation, but it won't start flashing. ADB or fastboot do not work on bootanimation, as the ROM is freshly installed. I presume it has ADB turned off by default...
I'll be grateful for any ideas and suggestions.
No escape , man. I tried all ( check this rom for galaxy note 9 )
Nice...
I went to service center, they said they can fix it for me. 40 euros for reflash (download mode isn't necessary), 100 euros for complete unbrick. I hope the unbrick isn't necessary and the bootloader is intact. I'll post with update.

t870 S7 unlocked bootloader stuck in loop

sm-t870 unlocked/rooted stuck in bootloop
cannot enter recovery or download mode, or even seem to shut the tablet completely off.
any combination of buttons turns the tablet on with the message "bootloader is unlocked press power key to continue"
so holding power+volUP, must be let go to press power which seems to interrupt the button combination
power+volDOWN seems to shut the tablet off for 5 seconds but it automatically turns back on.
having plugged into laptop seems to make no difference.
help!
Hi man, have you fixed this issue? I'm having the exact same problems as yours. I updated my Magisk it just went bootloop.
Thanks!
Plug into PC then Power+Volume Up got me into recovery mode
