[Q] How to reboot into recovery? - G2 and Desire Z General

I rooted my G2 about two months ago. I'm currently using MIUI, not the latest but the one before it. Somehow, my phone got turned off and when I tried to turn it back on, it was stuck in a bootloop. I have a custom recovery image so I don't know if that affects anything. I tried to reboot into recovery by pressing volume down and power, nothing happened. I then did volume up and power. It vibrated three times and the orange light started flashing. I pulled the battery and now when I try to turn it on, nothing happens. So how do I reboot into recovery and so I can restore my backup? Any help/suggestions would be greatly appreciated.

Never pull the battery during something like that. It sounds like your bricked. Someone else confirm?

I don't think it's bricked. I plugged it up and then Clockwork came up so I selected reboot now. Clockwork came up again so I tried to restore my latest backup and the screen went black. I'm going to let it charge and then give it another try.

Ok good. That's lucky because whenever you pull on a boot like that, it usually bricks. If you have the option, try to re-flash your ROM. Maybe even try stock. If you were getting a black screen, it's most likely you flashed incorrectly.

Ok, I was able to boot into recovery and now I'm restoring my backup. I don't think I had a custom recovery image with this one so hopefully I won't get stuck in a bootloop. When you say stock, do you mean before I flashed MIUI (it was the first rom I flashed)? Thank you for your suggestions and all of your help.

first install adb on you PC, it helps a lot in these kind of cases.
1. try "adb logcat", it would tell you about what's going on in your machine.
2. once you get your adb working, try "adb reboot recovery" to see if it could boot your phone in recovery.
3. if after doing everything you fail to boot either your phone or in recovery then try using PC10IMG to boot a stock rom and then re-root your phone.

I got it back working. For some reason, I'm just starting to think that it needed charging (the battery had been out for about a day or two). I do have adb installed and configured on my computer since I needed it to root. Thank you for your suggestions, I will definitely rember them if this happens again.

lol of course when you get black screen and led blnking means your battery begging for juice, you're lucky that when the phone booted back in recovery and you tried to restore a backup the phone went off before actually starting to restore, that would've bricked your phone
DO NOT FLASH ANYTHING WITHOUT AT LEAST 40% OF JUICE LEFT

Help with screwed up clockwork recovery

In an effort to get back to stock I took things a step too far and now have a phone that won't power on. I had successfully rooted the phone and installed Rom Manager and flashed the clockwork recovery and immediately created a nandroid backup. Sometime later my phone started acting funny... usb connected/disconnected events when it was not plugged in, crashes, etc. I felt confident that this was a hardware issue (started after my daughter chewed on it when I wasn't looking). Anyway, I followed the instructions here in the dev forum (True Stock 2.1 firmware for vibrant) for the vibrant to get back to stock ( I apparently can't post the link because I'm new...) . So that I'd be able to try and get it replaced. I kept noticing that no matter how hard I tried clockwork was still installed... then I did the bad thing. I should have known better, but I made the rookie mistake and deleted the clockwork folder from the internal flash. I don't know what possessed me to do it, but I did. Since then the phone doesn't seem to boot. I can get it into download mode to flash images from odin (battery out, battery in, volume up + volume down, connect usb and download comes on). And after a successful download it seems to restart ok. But if it crashes (which it is now prone to do) or is powered off it won't boot after that. Worse I can't get to the stock recovery either.
I'm hoping that someone who has a nice rooted stock phone with clockwork installed can just help me get a copy of that folder back and everything will be fine... if not I may just have to see if playing dumb with tmobile will get the phone replaced as is...
Thanks in advance for any help.
Are you talking about stuff in /sdcard? If so, that won't effect the boot. You could delete everything in there and not change anything. Some apps might not work as you will have deleted their data, but if you're flashing a stock ROM with Odin, that's fine.
Enable debug mode in the settings and use "adb reboot recovery" at a command prompt. That should get you to the stock recovery. Try a factory reset from there, that might help. If not, delete anything in /sdcard that's not supposed to be there and swap with TMobile as it sounds a hardware issue at that point. Don't forget to keep your external SD card if you've replaced it.
Is USB debugging on?
When you get the phone up, can you connect to it via ADB and then adb reboot recovery or adb reboot download?
Thanks for the suggestions. I did get the sdk installed and used adb to reboot into normal recovery, so it's not completely boned. Since I could use adb for resets I went ahead and followed the rooting process again and reflashed clockwork. The phone still won't boot on it's own. I'm starting to think whatever was going south with the hardware has continued to get worse. I'm going to use odin to get back to "true stock" again and try to use adb to reboot into recovery and do a factory reset suggested above and see if that helps.
Thanks again.
I went back to stock with odin, ran the factory reset, and still can't power up normally or into recovery. I can get into download though, load with odin, come up normally after the reset. I'm going to try giving it back to Tmobile in it's refusing to power up state and see if I can get them to swap it. It's as stock as I can make it so the problem should not be mine.
Thanks again for the help.
FWIW - i just installed Rom manager this morning, the premium version, and today experienced 5 force closures, one on google maps
before this i've had maybe one FC some 2-3 weeks ago - and like you i did a clockworkrecovery backup or nandroid backup

Bricked and won't boot following attempted Samsung update (16GB Wifi Retail)

A message popped up from Samsung to install an update (I had been pressing cancel for the past week on this update). It says click OK to reboot and apply update (something along those lines) so I do. Now I am stuck with a tablet that won't boot. If I hold the power button it says "Samsung Galaxy 10.1" after about 12 seconds, but then it goes away and back to darkness. Nothing else. Holding power and volume up does nothing.
Someone know what is going on and have any idea how to resolve?
The best way is to restore any backup you have from cwm recovery. Else grab a stock firmware and flash it with ODIN or if zip than CWM recovery. For luck, try clearing cache and data in recovery, first!Perhaps it may work saving you all fuss of flashing a firmware.
I cannot even boot that far too get into recovery. And I just noticed that although I can't boot, the backlight is on (on a solid black screen).... wtf
You can't hold volume down and power button to enter recovery?
Nope. I plugged into my computer and for some reason with the USB connectd it let me enter recovery. Flashed a backup and rebooted, but now I have no wifi... im confused.
it occured once to me when i tried to overclock, it never worked except when installing a new rom... Try to root the device and then install a new rom
OK, was a helluva night messing with ROM and kernel installs... I have yet to go back to completely stock (that's next up tonight, unfortunately), but I installed Starburst ROM and the Wifi still didn't work so I then installed pershoot's kernel and now when I boot the screen is extremely distorted kind of like this: http://t1.gstatic.com/images?q=tbn:ANd9GcTsKa5IoQxnesGdUjykWDDggoQZ38yZ2VXSgPAQ09NOCnETzl9-
As a side note, when I say the wifi is not working, it still shows all networks and allows me to connect just like normal. However when connected no apps can access the network...
Can someone point me to a thread on how to revert EVERYTHING back to stock so I can start fresh? TIA!!

Should have all the files you need. From where you are now I would flash the stock OTA 3.1 or TW then flash the stock recovery and do a factory reset from that recovery. That should get rid of the garbled screen.
Thanks buddy. On my way to grab the files now
I heard the update was pulled as it sometimes rewrites the bootloader improperly. You might need to send it in, unfortunately.

Issue with Rooted Nexus

I rooted the Nexus a few days ago and everything was working fine had to do a reboot this evening but all it does now is sit at the Google padlock splash screen and it won't go any further.
I've tried going into the boot loader and running recovery but it just goes back to the Google padlock splash screen.
Is there anything I can do to resolve the problem and try and recover the Nexus or is it bricked?
Any help would be much appreciated.

This is "normal" behavior (the bootloader needs to be fixed). Just hold power until your tablet turns off and then you can turn it back on again. Other methods for accessing recovery still work, like the reboot menu of a custom ROM or an app that can reboot into recovery like Quickboot. If you can't get your tablet to boot correctly though, then while your tablet is connected to your running computer, try to enter recovery from the bootloader and it should boot into recovery.
http://forum.xda-developers.com/showthread.php?t=1766475 <- if u have tried everything on the tablet, and still not working, than this tool will solve ur problem, it install a stock version on it and data will be wiped
hope this help,
cheers

Worked a treat once connected to the USB on my laptop and got into recovery and restored the Nandroid backup, then restored my data and system backup from Sunday with Titanium and was back up and running in half an hour.
Thanks

[Q] Can't boot into recovery; is this my only option?

Was checking facebook earlier, it stopped responding and just went to a grey screen. Decided to restart the tablet. Now it's stuck in a bootloop and will not turn on. Tried going into recovery but once I select it, the next screen I get is an android with a red triangle/exclamation point. It won't go into recovery and I'm not sure what to do from here. My laptop won't recognize that I have my tablet plugged in either, fwiw.
Is this thread my only option or did I miss something else? This link sounds complicated, but if it's my only option, I guess I'll give it a shot. http://forum.xda-developers.com/showthread.php?t=1907796&highlight=can+t+boot+into+recovery+mode
It can be anything from hw failure to corrupted data. I guess your tablet is stock, without custom recovery or anything. If this is the case, you should try restoring a stock image by that guide or by using a toolkit, like this one. If you have custom recovery on your tab, you should boot into bootloader and reflash the custom recovery with fastboot, this way your data might be saved.
Completely stock. I'll download Wug tonight after work and give it a try since it seems easier than the link I provided.
I didn't back anything up, but that's okay, I can live with that. Just want to be able to use the tablet again.
Well, got home and decided to give recovery another shot. I got it to wipe all data (was pressing the vol up button for too long earlier), but now when i go to reboot the device, it's just stuck on the X screen.
Any advice on what I should do at this point? Should I still try wug?

Emergency help; Stuck at LG logo

Solved!
Please buy hyelton a beer or a damn new phone. He's a hero.
This worked: http://forum.xda-developers.com/showthread.php?t=2432476&highlight=decrypt
Hey guys, but of an emergency here...
I'm stuck at the LG logo after flashing the Pacman ROM with the latest unofficial CWM, and it seems to have failed at Formatting system. All four touch buttons on the bottom were blue, as if they had been pressed and highlighted. No response from anything.
Reboot. Then it got stuck on the LG logo. I can't access CWM anymore, holding power + vol down does nothing, I just go back to the logo. I'm running a D802.
This was a pretty standard flash for me, I have done this many times, so I was confident in it, but now have no way back into a phone I desperately need within hours.
Process went as follows;
Full wipe, format, initialize install, it failed/crashed/whatever, rebooted, now stuck on logo, unable to access CWM, and obviously unable to access ROM.
USB Debugging was on, but as the ROM doesn't exist anymore, not sure how much help that'll be.
I'll gladly go back to either CWM or TWRP, as well as stock ROM or whatever. I can sort all that out later, right now just need things back in running order.
Edit1: I can't even turn it off. It simply boots up again, so now also worried of damaging display or battery.
Edit2: It's not showing after entering "adb devices". List is empty.
ANY help appreciated.
I'm running Windows 8, and no, I will not be able to reinstall to W7 or Ubuntu.
Thank you
