Problem with CM 12.1 - Android Q&A, Help & Troubleshooting

I bought a phone from China - JiaYu G4s. It came with Android 4.2.2, so I decided to install kitkat. Kitkat worked well, but I knew it is not enough. I found Cyanogenmod 12.1 for that phone. I installed it, but forgot to wipe /data and /cache and it was crashing. I tried to access recovery, but I didn't know how (Clockworkmod recovery carliv 4.4, I had a custom ROM, where when I long pressed power buttom, there was a option to reboot in recovery). My preloader never worked, so I couldn't access files from computer. So I rebooted my phone and in setting press factory reset. My phone rebooted to recovery and a sign "Processing" appeared. But It crashed and I had to reboot my phone. Now I'm stuck in boot animation, I can't go recovery, I can't access my phone from computer. I can't do anything (I think so). Can someone help me?

Power off your device then try these buttons one by one to enter recovery
1. Power button + Volume up + volume down(this one should work)
2.Power button + Volume Down
3.Power button + Volume Up

Try volume down + power button to enter the fastboot mode and flash your recovery or rom again

[Q] Flashed new ROM without emptying cache. Can't enter recovery mode. HELP

Hi all
I have used search and I can find results that pertain to other devices but not specifically Galaxy S3 (I9300).
I've been trying to flash a new ROM onto my phone.
To do this:
- I rooted the phone using Odin and installed CF Root + CWM package.
- After doing this, I did the 3 button reset to enter Recovery mode. However, the phone always entered into Download Mode (Odin Mode / "Downloading... Do not turn off target !!"). I was never able to enter Recovery mode.
- So I couldn't use the Recovery mode to install the ROM.
- Instead, I used ROM Manager to do the install (Cyanogen 9) but I did this without clearing the cache.
The result:
- Now if I leave the phone to boot, it enters Cyanogen 9 boot screen but stuck here looping.
- if I try to enter recovery mode to clear the cache, it only gives me download screen.
I've tried a few different uploads to get recovery mode (and it successfully uploads the files I send using Odin) however the phone still enters download mode after the flash.
I'm worried about doing the wrong steps if I follow advice from other sub-forums relating to other devices.
Any tips?
Many thanks.

The three button reset is power button + Home + Volume up to enter into recovery..
You are going to Download mode because you are pressing Power button + Home + Volume down key ...
Read this guide
Recovery mode is volume up while pressing home and then power.
Try this first and see if you can access recovery, if not then flash Philz recovery via odin and then boot into it to clear data, cache etc.
Make sure you read and understand how to use both odin and recovery before you start, otherwise you can brick your phone.

Thanks MoonBlade.
Funnily, I was pressing power + home + volume down to get download mode.
I tried pressing power + home + volume up, which successfully got me into recovery mode.
Strangely reversed.
This seems to have resolved the problem.

Cant access recovery via powerbutton and volume up

Edit: I figured this out... I had to hold volume up and down at the same time while powering up. Also the phone needs to be unplugged. IF its plugged in it will go to Download mode instead of recovery.
Hello,
I recently Went from the stock ATT rom to CM 10.2, and then to Omni.
I can not access CWM recovery by powering the phone on while holding volume up... Ive also tried holding the soft home key.
The only way I can get into recovery is to open ROM manager and choose reboot to recovery. This scares me because if my rom goes haywire I may not have any way to get back into the recovery.
I have already tried re flashing CWM
any ideas?
Quick Boot
You can download the app "Quick Boot" from the Play Store, which has the option to reset into recovery (and many other options)

Phone only boots to recovery mode, power button only doesnt work in recovery mode

Recently did factory reset for my i9100, downloaded reboot manager and rebooted into recovery from that app.
Now I can't get out of recovery mode since power button doesnt work in there and my middle button is broken too.
VolUp and VolDwn work everywhere and I can turn phone on by power button.
Any help? I'm on 2.2.3
edit/ i also rooted the phone recently with kingroot via pc
Hi @noupls,
To get out of recovery mode, you need to take out your phone battery.
Once your phone is off, reinsert the battery. Then go into download mode (press and hold volume down + power button + home).
Once in download mode, flash stock ROM via ODIN (if you've already download the firmware files).
Saber.
With broken buttons, you're pretty much stuffed whatever you do with the device. You NEED to get them repaired/replaced ASAP.
In recovery, there should be an option
REBOOT SYSTEM (NOW)
With your broken buttons I'm pretty sure that'll be the only thing that works.

Stuck in recovery mode

I accidently flashed the lineage 16 recovery instead of lineage 17.1 recovery. I tried to install the 17.1 update through updater but my phone stuck into recovery mode. Neither I can boot into bootloader nor to android. I can''t flash anything. Power + volume down and connect the cable also not working to go into bootloader. Even bootloader option within the recovery also brings me back to recovery mode. ...adb devices command is also showing "device offline". Any help will be appreciated.
you should start from the beginning
is your bootloader still unlocked?

I can't go into fastboot mode. Is there any other way to check it?
Thank you @stukka2006 for replying me. I guess I saved my phone. So here what I did-
1. Extracted the stock firmware (Luckily I had one but can be found in the forum) and copied the dload folder to sdcard (as I was not able to access internal storage). (@stukka2006 your hint to start from the beginning)
2. Power off the phone and pressed Both volume buttons + power button simultaneously. After the vibration I left the power button while still holding both vol buttons till software update screen appears. But software update failed. So I just touched the reboot now option. The phone rebooted to fastboot mode.
3. I installed TWRP but was not able to reboot to recovery through commands and system reboot command brings me back to fastboot mode. So I again power off the device with cable connected and pressed both vol buttons. This time phone showed recovery screen (Should have worked with normal button shortcuts also, I guess) and I flashed the rom and rebooted normally.
Everything is working fine now except that I lost the data.
Happy you got all clear my friend !!!

You are quite lucky to have the stock ROM.
