My TabletPC bootloops and does not have a recovery mode... - Android Q&A, Help & Troubleshooting

Hi, i have a big problem. The internet didn't work and i wanted to reboot the tablet, then it just bootloops. If I press power button+volume down it will show up a screen with 3 options:
1) Recovery Mode
2) Fastboot mode
3) Reboot
If I press recovery mode it will still bootloop, the same for the 3rd option, but if I press fastboot it will show up the text "Fastboot..."
Can anyone help me?

[Q] Need help with possible brick

After installing clockwork recovery, my TF201 booted up and I accidentally was still holding the down on the volume switch and then accidentally hit wipe data. I turned it off as fast as I could and now my device can't boot. It hangs at the ASUS splash screen and I cannot even enter recovery mode with the volume button and power switch.
I cannot enter fastboot mode or any of those modes at all...

OK, with testing I found a solution for the problem
Here the steps what i've done:
1. Load the Flyer with the power supply unit.
2. From PC Commandpromt. Start fastboot flash recovery recovery.img. I've get the message "waiting for devices". I've used a old CWM 4 reciovery Image
3. Now connect the Flyer and Start with "Power + Down". Here was the surprise that now the Bootloop stops and i see now the Boot Menu. So I change here to fastboot and flash the recovery Image new.
4 Rebbot now an voila bo boot more and I can use the normal cwm recovery mechanism to recovery one of my old images... Perfekt

[Q] Getting out of Recovery Mode without power button?

Hi all.
I entered recovery mode (through the advanced reboot menu in CM, but that doesn't matter).
My power button doesn't work, and everything was fine without it until I entered recovery mode - now I can't exit it.
The problem is I can't select "reboot system now" from the recovery menu because power button is the selector (and as I said, it doesn't work) so I tried taking the battery out and then turning on but it enters recovery mode every time.
I didn't do anything through recovery mode so no harm was done to my working system.
Also, my PC doesn't recognize my phone when in recovery mode so I can't run adb commands. I don't know why - I have the latest usb drivers installed.
Is there any way to exit recovery mode without the power button?
Thanks a lot. :good:
Use touch CWM or Philz touch or TWRP
Ended up with fixing my power button.
Thanks any way.
By the way, discovered rainbow mode (volume down + up together) of CWM... pretty funny.

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.

ADB reboot recovery doesn't boot recovery mode

Hi, I'm trying to get root access to my phone, and have installed ADB and everything, and it's all working, but when i try and boot my phone in recovery it just reboots it normally.
That command doesn't work for every phone. Is it an LG?
No it's a sony xperia z3 compact
Have you tried the common android vol+ (sometimes vol-) and pwr buttons combination to get into the boot menu that lets you choose recovery?
