Can you boot your phone in CWM recovery?

You should charge your phone first.. Make sure your phone's battery is fully charged.

charge the phone, enter download mode while connected to a pc, flash a stock kernel with odin then flash the rom. does the recovery mode work?

Hello, first thanks for the answer, im sure the battery is fully charged, becouse i get 2 batteris off my friends and i asked them if the baterry is charged and them tell yes, and i can't get recovery mode, if i press +vol and home button and power button the phone start with the samsung model screen and power off on 3 seconds, i dont know what to do. Thanks

maybe your power button is stuck, or other button is stock

Get it repaired (talk to your phone company about this e.g. Sony), i think its the only way to fix your phone.:thumbup:

- try charging the accu externaly
- while on booting try combos of vol +/- and power button to access recovery menu
- dissasemble and check the buttons

[Q] Galaxy Fit BRICKED!!!!!!!!!!!

Guys need serious technical help..............................
i have rooted my phone with super one click all things were going fine.installed rom manager to backup my stock ROM and committed a mistake and installed wrong cwm and tried to backup my stock rom.selecting the backup option it Suppose reboot my phone in download mode which doesn't happen. and now i dose not have any access to my phone.
I searched whole forum and haven't found any solution.please help me.
Need guidance..
download and install pratyush.creed rom using odin and ur phone will be fine again
Bricked Screen (A.K.A. phone-!-pc or Black Screen of Death)
To recover from this problem, you'll need to get into the Download Mode.
Black Screen of Death:A fully bricked phone will not boot, or display the charging logo when connected to a USB charger. This presently cannot be recovered from any recovery attempt, it will require the phone to be sent back to Samsung and be serviced.
This screen does not always mean your phone is bricked. If you have a hardware locked vibrant, maybe, however, if your phone is not hardware locked, unplug the USB cable from the phone, Hold down Vol UP+Vol Down+Power, the screen will flash black, continue holding down all 3 buttons, you will see the "phone--!--PC" screen again, continue holding all 3 buttons, the screen will flash black again, release the power button only. This will put you into Download Mode.
If this does not work, open odin. Then connect your usb cable to your phone and computer. While the USB is plugged in and Odin running press and hold volume down + Home + Power. Once the black screen comes (flashes) release the Power Button. It should get into download mode.
Additionally it is possible to get into the Download Mode using a kind of micro-usb connector, modified with a 301k resistor as showed in this video:

I try and schema whit modified resistor but nothing. i measured the level of battery it was at 2,4 V after some seconds it down to 0. Maybe it the battery? i charge all the night and next day i put on USB on PC all the day before it die. Maybe i broke the battery and no phone?

lets see what they will do.i'll inform u what they did to my handset..............................

[Q] How to boot into recovery without ROM or power button

My Galaxy S3 just faced the bootloop issue because of a faulty power button. I had CM12 installed, so couldn't use warranty. I opened up the phone, and cut the power switch off with a razor blade. Now, I can boot to download mode using the volume and home buttons while plugged in, and cancel download mode to boot phone. My issue is that I experienced a huge battery drain on a ROM, and dirty-flashed another ROM over it. Now, the phone won't boot. I'd like to go back to CM11, but can't figure out how to boot to recovery. Thus, this is what I need:
A way get to recovery, without using a power button, or booting up the phone
Thanks for any help

If you can boot to download mode, you can get to recovery mode. Here's how. I figured this out when my power button broke and I removed the power switch from the phone's motherboard, so it should work for you:
1. Take the battery out of the phone and unplug it from USB power.
2. Plug in USB power.
3. While holding down the volume-down button and the Home button, insert the battery (this is a little tricky).
4. The phone should start and warn you that you are entering Download mode.
5. Press Volume Down to reboot and then *immediately* push and hold Volume Up and Home simultaneously. The phone should reboot into recovery. Mine does.

Yes - thank you very much! FYI - when I read @Jacquestrapp 's instructions, I suspected the battery gymnastics wouldn't be needed since I had already learned (in this informative video) that I could boot the phone from a powered-off state WITH THE BATTERY INSTALLED by plugging in USB power and immediately depressing home and vol-down. This gets you to step #4 above, and proceed from there.
So this is cool! My trusty-old d2vzw's power button had stuck in the "On" position last September as they apparently tend to do, so I set it aside as a brick and bought a used HTC One m7. Needing a WiFi skype device for a friend, I searched and read about scraping off the S3's power button and operating without one. Now, I see how much I missed the S3's AMOLED display colors and contrast compared to the 1080p display on the m7, and I'm reluctant to part with the S3 .
Help - when pressing volume down it does not reboot.
I9300. could there be a difference in different regions?
edit: volume down switch (not the plastic bit, the hardware connectors) was a bit flimsy so I had it replaced. Still not working though.
I read the instructions wrong. I was using a USB jig to directly boot into download mode. But I need to get to the prompt before it. However, when following the steps the phone just begins charging instead.

Boot the phone, when it gets to the unlock screen try connecting it to PC and open an adb terminal then type:
adb devices(press enter, if it returns a serial number your device is recognized)
Then type:
adb reboot recovery
Or
adb reboot bootloader
Try unlocking it and typing the reboot commands while it is frozen.
Or you can order a USB jig for $5 US or less from eBay.
Or you can use an old USB cord and a 300k resistor(or any combination of resistors equaling no more and no less than 300k) to make your own jig, there are videos on YouTube for making your own jig.

I don't know if you are been cheeky or not, but I will go check if I can actually touch the option. Lol.
In case I can't what ROM can I install via Odin that will give me touch recovery. Or what other options do I have?
I really don't want to take it apart again to remove the plastic button so I can short the power leads with a wire to mimic a power button press.

if you install gravitybox and xposed there should be an option to turn on the screen with the volume buttons (I'm not sure though, it might have been another module) so you could use that as a temporary solution.

with phone turned off, (you can remove the battery and re plug it), hold the volume down button and connect it to the wall charger(do not use PC,it will trigger lg download mode), then you will be able to go to fastboot.
Once there you can:
fastboot reboot to boot to normal OS
fastboot boot twrp so you can install a rom or any other mod

fastboot reboot - to boot into normal OS
fastboot boot twrp - to boot twrp

Oh i didn't understand, thanks a lot it's working
Now I'm just waiting my new power button
i had this **** sorry for swearing i thought its something with my ROM CM13 Nightly I tried the repair service they said that they changed the power button no data was deleted so its probably the button but some one had a guide how to get the phone out that **** using your PC and manual ADB commands ( No program command line only )
I need help with this issue
when this problem reached me it was a meter of replacing the power button itself (it's like stuck there) by the way my phone was still under warranty so they changed it for me

, can't enter into recovery mode, c'ant enter in download mode, even my pc and odin doesn't recognize the device at all, please help I can't afford a new one.
Thanks in advance.
Just flash stock rom with odin, conect to pc pressing vol + and vol - to get download mode
It doesn't react with + - buttons, that is why i can't flash it
What is the last OS you are running?
If the phone keeps restarting, first connect the phone to your PC via USB cable.
Then
1. Keep Vol+ and POWER pressed.
or
2. Keep Vol- and POWER Pressed.
Thank you but it seems that my motherboard is damaged

I do not think it has been damaged, try pressing vol + vol- boot at the same time a couple of times and then the third release the vol + i the boot and it will restart in dowload mode. then flash with odin each of the partitions of an original rom.
good luck

Hey,
I have the same problem with the bootloop and the corrupted locking screen. I'm able to boot into download mode, but I can't figure out which system to flash. I tried several ones, but none of them worked... and I can't get back to the factory recovery. If somebody has an idea which recovery system could work I would be very pleased to know.
Software used to Flash: Odin
Device: a750fnxxu4ctc4
