Hi, I have a S7562L and tried flashing cm-11-20150323-UNOFFICIAL-kylessopen-RC3.zip from here: http://forum.xda-developers.com/s7562/development/cm11-samsung-galaxy-s-duos-kitkat-4-4-4-t3024762
I have successfully booted up in download and recovery modes, and have also flashed TWRP recovery. Due to bluethooth not operating correctly I deceided to flash back to a stock ROM using ODIN. But now it stays in a bootloop with the glowing "SAMSUNG". I have tried several stock firmwares but same result. I want to try to erase the cache but I can no loger boot into recovery.
Any suggestions on what to try next?

First you should not post this in Android Development forum, Q&A, Help & Troubleshooting forum is there for this query
Go to downloading mode, then flash stock rom
When whole process is completed and samsung logo is displayed on the screen, take out the battery and place it in again
go to recovery by pressing volume up, down, home and power button and leave it after phone vibrates and shows device model name
factory reset the device from there
This may work for you

Sorry about that I didn't know. (Moderator edit... moved to Q&A)
Anyway I found a way to get in. Instead of pressing the recovery keys from power off, this time when it was in the boot loop I pressed and held the power button and just as it was powering down when the screen went blank, I quickly pressed and held (all four) recovery keys, and that got me in. From there I could the factory reset and wipe the data and caches and all is back to normal now.

Dear experts,
Phone model: Karbonn A9+
Rom: Custom Rom Hyperion Skyfall
When I hold the power button, the phone turns on and off, No problems with that.
However, when I press volume Up+Power, I get a green screen saying FASTBOOT at the top left corner and that’s it. Nothing happens from that point.
when I press volume Up+Power, I get a green screen and holding the buttons past that I get a red screen saying RECOVERY at the top left corner and that’s it. Nothing happens from that point.
However, when I press volume down+Power, I get a black screen saying ENTRY QPST DOWNLOAD at the top and that’s it. Nothing happens from that point.
I have to remove the battery to turn my phone off.
Moreover, I tried a factory reset erasing internal and external storage, after erasing when the phone is rebooted and gets stuck in the start-up screen. I removed the battery and powered on the mobile ,no problem at all the phone turns on but not resettted.
What I did?
Tried to install latest CWM through recovery, updated it but I pressed something instead of restart your device.
What should I do to make everything work again? I am a noob in Android, please be extra patient and illustrative
Many thanks in advance

Hi,
I think that this post couild help you => Karbonn A21 > A21 General > Karbonn A9+/A21/CM Flare Development Thread > Post #947 > Entry QPST Download !!! Fixed !
I have a rooted LG G2 (AT&T) running Android 4.2.2. I rooted it and then tried to install TWRP recovery. After attempting to flash a TWRP image using Flashify, the phone rebooted showing the Android guy with a red triangle (so basically the installation failed). I held down the power button and the phone booted up like normal.
Alright, now later down the line the phone received an OTA update (probably Kitkat). When the phone "booted", the LG logo flashed on the screen and then stayed black (the backlight was still on). If I hold the power button+volume down, the phone will just reboot. Without really being able power down the device, it seems I cannot get into download mode. Also, if I hold down power button+volume down for a long time, the notification LED will blink red (5 times *stop* 5 times...) until I let go.
Eventually I tried the power button+volume down button multiple times, pressing it in different timing intervals and managed to get it into factory reset mode! I followed the prompts but alas the phone will still not boot normally and the screen backlight is still on.
I hope this is the right forum, I need help fast.

Hi to all. I have a problem with my tablet.Some days a go my tablet started to bootloop. I got the ZTE logo and then reboots again. It's the same thing when I tryto charge it. For a couple of seconds it shows the battery icon which is low and after that it's like it shuts off and shows the battery icon again. Over and over. Not only that but when I try to enter to recovery mode I press power + volume up and I get 4 boot modes recovery,fastboot,normal and UART.When I choose recovery mode the screen goes black.no android icon what so ever. I want to recover my files from it and flash it with new rom.
Any ideas?
Ok I solved the first problem.It tyrned out that it had not enough battery.I did charge the battery without the tablet and it has enough power to boot to recovery menu. It has the option backup user data data but I get Mount data error. I can't think a way to recover my files without factory reset.

Okay so I have a bit of a situation and looking for some helpful advice, I'm not a complete novice but I seem to have gotten myself VERY stuck.
The Specifications:
Samsung Note 3 (rooted)
TWRP
Safe Strap
Rebooted recently and was in TWRP and accidentally chose "Recovery", phone now continuously Reboots into Recovery Mode in the upper left of the screen. I've tried to do the Volume Up + Power + Home button to no avail and every other combination I can think of, resulting in The same .. Reboot Recovery Option in the top left after about 10 seconds it Vibrates twice and reboots again.
I can't access TWRP, can't access Stock Recovery, Can't plug it into a PC as it just reboots over and over again after it gets power. Read a few things about Fastboot (Don't know if Note 3 Supports that, and Maybe Odin but I can't see how I'm to flash anything if it just immediatly reboots as soon as I plug it in)
HELP!

Was trying to put a new rom on an old samsung tablet but I accidentally rebooted after I deleted everything.
In recovery nothing works. Can't mount usb, can't access flash, can't backup, can't flash update, wiping again does nothing, factory reset does nothing, ect all buttons do nothing.
Then that other boot menu you get by pressing power and the other volume button says "downloading do not turn off target!!!" and has a pic of the android android shoveling something while the whole picture is a yellow triangle like a traffic sign.
Its the gt-p1000r which means I can open it up and make it into a developer edition with a hardware hack but I have a feeling that nothing would come from that.
Thank you for your time.
Hello,
Volume down+power boots the device to download mode. If you can boot to that mode then you can flash the stock firmware via Odin on PC.
You can find the stock firmware for your specific model number by doing a google search for "stock firmware for (your model number)", that will probably give you some links to Sammobile or samsung-updates where you can download your firmware.
