Samsung galaxy A51 (a515f) stops on Android logo - Android Q&A, Help & Troubleshooting

Days ago My phone restarded and stoped on the Samsung logo.
I tried to do a hard reset with the recovery mode. After wipe al data and restart the phone it stop on the logo again.
Also, after the recovery menú launch it appears two images. Sems like the phone it's going to update and then appears an Android logo with the "no comand" words. Before this the recovery menú appears.
What should I do to get my phone back? since performing a hard reset from the cell phone does not work thanks

@RicardoPeyro
In order to bypass the NO command screen you can try the following
Boot phone into Recovery mode
When Recovery Menu comes up select "Wipe Data / Factory Reset" or "Wipe Cache Partition"
Once the process completes, you can reboot your phone by selecting in Recovery menu “Reboot System Now”

Phone lockups after boot.

UPDATE (30.05.11):
My phone starts up, but then hangs after some secounds. It started happend without me doing anything(I ofcourse had rooted my phone, but that was days earlier)
I have tried to flash Samsung KE7 firmware, with and without .PIT file, I have tried Villianrom v1.1 and I also tried to enter recovery and wipe data/factory reset and wipe cache.
Nothing seems to help, the phone still doesnt work.
I ordered a USB jig so I can reset the counter before I try to get it on warranty.
But before I do that, is there something else I can try?
Is my really phone defect?
What is samsung policy when you have flashed custom roms?

You saved the original firmware ???
Or do you know what your original firmware was . Probably WKDD

Flash back to that but i would wager you are doing something wrong .
Did you extract the tar file I9100XWKE7_I9100XXKE4_I9100XEUKD1
from the zipped file first guess .
jje
Im flashing I9100XWKE7_I9100XXKE4_I9100XEUKD1.tar
And it flashes successfully. But when one flash like this it doesnt delete everyting.
Still having issues with my phone, its hangs on boot, or right after, when I try to enter my gmail acount.
Tried flashing it with PDA : I9100XWKE7_I9100XXKE4_I9100XEUKD1_HOME.tar
and pit file u1_02_20110310_emmc_EXT4.pit
DON'T use the pit file, only put the firmware in PDA and then press start.
I had the same Problem, just like you. I forgot to wipe the cache/data in the bootloader, thats why it goes in a boot loop.
first you have to go into the bootloader(shutdown phone, and then press home+volume up+power button). then once you are in the bootloader, wipe the data/factory reset, and then wipe the cache.
after you have done that, you can flash a new rom.
I tried that earlier aswell. But I can try again with the new firmware I downloaded.
This is what I tried now:
Enter rec mode (Power + Volume UP + enter)
wipe the data/factory reset
wipe the cache
Battery inn and out
Enter Flash mode (Power + Volume down + Enter)
Flashed I9100XWKE7_I9100XXKE4_I9100XEUKD1_HOME.tar with Odin3 v1.85 with only "Auto reboot", "F. Reset time" and PDA file checked.
After the flash, the phone reboots and Lock up on the "S" logo with "Samsung galaxy s II" underneath.
Waited 5 minutes, still locked on the same screen.
Turn the phone off and on, and it lockup where I input sim pin code.
I again turn the phone off and on an it locked up at the "Touch the android to begin, even before I get asked to enter pin..
I turn of and on the phone, And I get to the point where I can am asked to enter google infomation, and then the phone reboots itself and lockups on the "Samsung Galaxy SII GT-9100" logo.
Tried to enter Enter rec mode (Power + Volume UP + enter) and wipe out everything again, and reboot. But the system still hangs.
But I get this error message when I enter Rec mode and when I flash, is this normal?

Five mins doesn't sound long enough to me. My first boots took much longer, I swear. don't worry about multi csc error, I get that.
While you're at it, buy a jig and reset the custom rom counter to protect yourself

Okay, I can try to flash again when I come home from work today.
How long should I wait? 15 minutes?
Tried flashing again, and I leaved until the phone booted. (Happen very quick this time)
The phone still gets in reboot loop, or it hangs. Sometime its boots up fully(I can move around in homescreen) and then it hangs/reboots.
Tried flashing many different roms, but same symptoms.
Do people have an idea what I can do?
Is my phone defect?

[10.1v] Can't get into recovery. Only Samsung Boot Menu and Fastboot

I wanted to completely reset my Samsung Galaxy Tab 10.1v (did factory reset and also manually wiped cache and system in the recovery menu.
Now, when I rebooted I noticed I was stuck in the boot menu (the logo plus the unlocked lock). Funnily enough I can access the adb menu (when I type adb devices) my device is shown. However, when I type "adb reboot recovery" I get stuck in the charging screen 'I see the battery with a loading icon". When I'm at this state, my computer suddenly doesn't recognize the device anymore
I do, however, have access to the fastboot menu. My device is also recognized. I just can't get into recovery.
Is there a way of restoring the recovery menu through the fastboot menu?
Cheers

Need help phone stuck in boot

Hi,
So i tried to update my galaxy s6 edge t mobile to the latest firmware and once it did, it got stuck in the samsung screen and wont boot. The phone was rooted before, and now it just stays stuck. I have restarted the phone and now I have tried flashing the phone using Odin. It keeps saying failed and it shows the following:: " SW REV. CHECK FAIL. DEVICE: 2, BINARY: 1". I have tried downloading the firmware but it just keeps failing. When it updated, it should have updated to 5.1.1 since thats the latest which means i cant just put any other one right?
I dont know what to do to be honest, if anyone can help me i would really appreciate it.
anyone?
Have you tried using Smart Switch to restore Stock firmware?
There are a few solutions mate
1st One:
1) Put your phone into download mode using "Volume Down-Home-Power" combo until your screen comes into download mode and still hold it untill the screen goes off.
2)Quickly switch to recovery mode using "Volume Up-Home-Power" in the black screen and get into recovery
a)if it loads something and says erased... please start from the 1st step again
3)Wipe cache/ factory reset do these things in the recovery mode then reboot.
you should be good to go. If not theres another solution.
--------------------------------------------------
2nd One:
1)Put your phone into download mode.
2)Connect ur phone to the computer via usb and open smart switch
3)Press view more button on the right top.
4)Choose the 1st option as "emergency recovery and restore"
5)Put your model and serial number (its on the backside of the phone)
6)then follow the instructions of the smartswitch
thats it

Ok so my phone stays stuck in the samsung screen and smart switch stays stuck saying connecting to your device. i really dont wanna try the factory reset thing because i havent backed up the files on my phone
Ok so i got to flash it with 5.1.1 using odin but once its done it keeps staying stuck in the samsung logo screen....again.
Just did factory reset and still gets stuck at the damn samsung logo..
I am willing to pay if someone can help me solve this issue
I also noticed that once the downloading portion of the phone is done, it says installing with the android robot picture, then halfway it says erasing and then it restarts and gets stuck at the samsung logo
=(
you need to do wipe cache and, wipe data and factory reset. That erasing part is normal. Your phone is not bricked. That android robot portion just verifies the stock recovery and partitions. No problem with it. just wipe cache dalvik and everything what you can find (there are 2 options already) on the recovery.

Huawei G630-U10 problems with booting.

Hi guys,
I'm trying to fix someone's Huawei G630-U10 but ran into some serious issues.
The device was stuck on the Huawei logo so the obvious choice was to factory reset to get the phone working.
When I go into recovery to "Wipe Data", it just says "Wiping data..." and then nothing. No formatting and no deleting seems to be done.
I downloaded the stock ROM (Update.app) and selected the option in recovery to "Update from external storage" and selected the file. It gives a message that it's rebooting into update mode to update, but then the device reboots and gets stuck on the logo again.
I've tried going into update mode (Pwr+Vol Up+Vol Dwn) and it just remains on the logo. So I guess only recovery mode works.
Since the recovery couldn't delete anything, I suspect the storage is faulty or corrupted.
PS: the device just stays on until I force to power down. Then it just reboots automatically after a few seconds and remains stuck on the logo until I power down again. This happens as long as I don't physically remove the battery to end the loop.
Any suggestions or tips?
PPS: I've search extensively for flashing tools for qualcomm based huawei but no luck. The official site just hands out the update.app firmware which only works in update mode (which doesn't work in my case).
