help!!! - G2 and Desire Z Q&A, Help & Troubleshooting

i just installed a custom rom and now i cant toch anything when it boots up. How do i get to recover my old rom back??

I installed virtuals btw and when i hold down power and vol down it doesnt boot into recovery is there a way to do the recovery with abd when hooked to the computer?

umm... i don't think this belongs in the dev section and you should edit post to merge doubles... but what method did you use to install the rom?

When u boot into bootloader via vol doen+power if you don't see recovery, select bootloader, then the recovery option from there. Use power button to select while in bootloader, use track pad to select in cwm recovery.
...and ya, next time post in Q&A.

This happened to me yesterday. I plugged the phone via USB while off then booted it went to recovery

[Q] Boot into recovery without Vol(+) button?

I got my phone a bit damp while skiing and now the + vol button doesn't work. I would like to keep playing around with Roms however the inability to flash an update.zip to boot into clockwork mod worries me too much.
Is there anyway to get into the standard recovery without holding the + and pushing power? Or possibly hard-flash clockwork mod?

---Solved, flashed recovery using unREVoked, works well now. Thanks everyone, back continuous unadulterated flashing---
Well, ROM manager can boot into recovery, but obviously that requires a working ROM.
Regards,
Dave
Install ROM Manager from the Marketplace, use the custom clockwork recovery image in my sig (fake flash). You can then install the custom recovery image from the root of your sd card using ROM Manager. To flash ROMs in the future, in ROM Manager, select the 'Install ROM from sd card option'. You can then use the trackpad to navigate through the recovery menu options instead of the Vol key.

Yeah I know I can get there from Clockworkmod, but the rom needs to be working. I'm worried about flashing anything else in case one of the roms is broken.
I've read that unrevoked rooted phones can do it, can I use the unrevoked method even though I'm already rooted with Paul's riskfree?
If you turn on your phone while pressing the "Back"button on the right of the (OJ)optical joystick, your phone boots in "Fastboot"
Then you select "Bootloader" by pressing the powerbutton
If one of your vol buttons still works, you can press it untill you've selected recovery
Et Voila

I can get to the recovery screen, black phone with red exclamation mark in triangle. It is at this screen I need the vol(+) button. Hmmm...not too confident about flashing roms anymore

Use UnrEVOked to permanently flash a recovery image onto your phone.
Regards,
Dave
From terminal
su
reboot recovery
Also works
Where to from here?
I have been reading up on fastboot, in which I should be able to restore a nandroid backup if flashing a rom fails. This doesn't need the recovery console, there is some contingency I guess.
Has anyone used unrevoked on a prerooted device? are the steps the same?
Gas
For instructions for flashing a permanent recovery image (UnrEVOked) are pretty straightforward. Please see the following link for more information:

Just make sure you have HTC Sync uninstalled beforehand. To remove UnrEVOked, simply flash your original RUU file, which will also return you to stock and remove root.

Can't boot to recovery using buttons after cwm recovery

Noob here... So I just bought a Galaxy S3, my second Android phone, yesterday through AT&T. I decided to root the phone right away and istall clockworkmod recovery using Odin for both. I rooted the phone first and then rebooted to make sure everything was ok and it was. The phone would still boot into recovery and into download mode. After this I flashed clockworkmod recovery and everything seemed to go fine ... Odin did it's thing and I got the green "pass" box. I then tried several times to enter recovery using the button press method and the only thing that happened was my phone turned off. When I couldn't get into recovery mode using the button press method I downloaded rommanager and tried to boot to cwm recovery using that method and got an error message that told me I first needed to flash cwm recovery to the device so I flashed cwm recovery to the phone using rommanager. After flashing cwm recovery to the phone using rommanager I am now able to boot to recovery using rommanager but I'm still not able to use the button press method and I also realized this morning that I am not able to enter into download mode using the button press method either. I really want to flash the stable cyanogenmod9 rom to this phone but am scared to without having the button press recovery method as an option incase anything goes wrong.
Just to double check, what button combos are you using?
recovery=from a powered down state.volume up,home button, and power. hold all three until blue writing appears on the top of the screen, then release all three buttons.
download=volume down,home, and power.
Also, if its not the method you used to install CWM, you could try the Snapdragon tool kit to install it as well http://forum.xda-developers.com/showthread.php?t=1746665

Yeah those are the button combos I am using. Thanks for the input I was thinking about trying to reinstall cwm recovery when I get home from work using a different method I'll look into the snapdragon tool kit.

You are gonna have to change 2 file names.
/system/recovery-from-boot.p
/system/etc/install-recovery.sh
Just rename them so that you can get them back if you ever need to update. I added -delete- to the end of mine. Reflash CWM through ROM manager & then try to manually boot CWM. Hit thanks if this does the trick.

[Q] How do I revert ODIN to custom bootloader and recovery?

I have a toro/i515/Verizon Samsung Galaxy Nexus (the CDMA/LTE one) running a mostly stock (but rooted and with busybox) Jelly Bean JRO03O (Android 4.1.1).
I screwed up my build.prop (and can't boot normally), so I attempted to boot into CWMR 6. To my surprise, cold booting holding the Vol + button started to proceed with a normal boot. So I cold booted with the Vol - button held.
And that shocked me even more. I'm staring at ODIN Mode. WTF? When did ODIN get on my phone? What happened to the bootloader where I could select booting into recovery, or the bootloader, or normal booting?
I've been scouring Google and this forum, and many other forums, and I cannot for the life of me figure out how to boot this thing into a custom recovery so I can fix my build.prop through adb.
I'm at a loss. I suck at using ODIN (I only started using it recently when I bought my GTab2 10.1 GT-P5113).
How am I supposed to hack my phone when I can't use ADB, fastboot, or a custom recovery (booting normally hangs also)?
The only thing I don't want to do for a repair is a full wipe. I don't have a way of backing up my data without ADB.
I've tried enclosing various boot, bootloader, and recovery images (img files) into tar files (archives) and sending them to the phone via ODIN using the PDA and/or the BOOTLOADER button(s). I've tried to see if Wug's Toolkit would talk to my phone via ODIN.
Nothing seems to change.
Help!!! Please!!!
Any of the following will do:
1. Tell me how to get adb working.
2. Tell me how to revert ODIN back to the normal boot/bootloader (that works with fastboot) - this would be best. ODIN sucks.
3. Tell me how to get to my files via ODIN.
Please help. This sucks.
*sheepish grin* - I forgot about holding BOTH Vol + and Vol - at the same time while cold booting.
(I can at least get into fastboot mode now)...
From fastboot, boot to custom recovery (use vol keys to highlight, power to select), reflash rom.
Or
From fastboot, flash stock but dont flash userdata.img.

The very same thing happened to me today.
I was on 4.2 JB (custom stock rom, only rooted) and I received a software update....it failed at doing it and then said something about not losing root. I checked YES and boom....wont boot. Stuck at ODIN...
Odin recognizes it but fails at flashing.
Fastboot works and boots into cwm recovery....but it wont boot into android...
What should I do...?
Sorry if I am rude by asking here.

use adb to push a rom while on a custom recovery. it seems you need to read them again, and pay attention to it.

After posting the above, I meant to indicate that this thread could be closed. I knew exactly what to do now that I could finally get into fastboot.
Maybe ODIN was on my phone all along, but I could almost swear that I used to get into fastboot by holding Vol - while cold booting, and that I could get into recovery by Holding Vol + while cold booting. I don't remember ODIN being there at all.
Anyway, the bottom line:
Fastboot loads with Vol + AND Vol - held down while cold booting.
I was able to reflash boot, bootloader, and custom recovery with fastboot.
I was able to boot into custom recovery from fastboot.
Once CWMR 6 was running on my phone in recovery mode, I was able to mount /system from the recovery menu, to use adb to pull /system/build.prop, to edit it, to use adb to push build.prop back to /system, and finally to use adb to change permissions on build.prop back to 644.
Am I crazy? Was ODIN always on my VzW GNex?
Was it always loaded when holding Vol - down during a cold boot?
Or were the Vol - and Vol + buttons (individually) originally used for booting fastboot mode and recovery mode?
If I had forgotten that, then I haven't be hacking my phone enough, as I haven't been in fastboot in a long time.

question/comment to old post
This is an old post I'm responding to but my A500 has been bricked for over a year. I just read, click the lock button and when I did, on the screen is "Bootloader v0.03.12 ICS:: Starting Fastboot USB download protocol and found a related post referencing "Odin". I, too, want to know how that got onto my tablet. Perhaps from the update.zip? Now I can't find any relevant information nor files to download which aren't corrupt or tampered with. Can someone perhaps take a moment to outline a plan of action for me and the significant files? I will gladly "donate" to whomever and by "time". Thx (little grey haired old lady) Smiles4Miles, VMD

[Q] A little question if vol up/down doesnt work

As the title says, my volume buttons doesnt work, i can live with that but i got a small problem .. i have MW Redux ROM installed on my Desire and if i want to change it to something else, the only way is to press the Power Button and go to Reboot to Recovery. Okey, but if i will flash a new ROM and something will go wrong, or the ROM doesnt have the Reboot to Recovery option, how can I go to recovery without this option or power up the phone and then press the buttons? I know if the ROM is installedn,there are apps to reboot to recovery BUT if i will be in the recovery mode itself and something go wrong like endless bootloop etc.. and i want to change the ROM or fix the problem in recovery, is there another way to go into recovery mode, like through a PC or something? Thanks

Power + back button wil get you to bootloader but you won't be able to select recovery. You can, however, go from bootloader to fastboot usb and enter recovery via adb on your computer

Cannot enter a recovery Oppo find 7

Dear all,
im using oppo find 7 and now i have problem to enter a recovery, when i press power button + vol down, screen show fastboot, all this happen after i root my phone using KingRoot, im planning to install CWM to replace recovery. but also fail..:crying::crying::crying:
NEED HELP FROM PROS... THANKS A LOT....
Did you try pwr + vol+ buttons? Anyway if u have just rooted you need to go into fastboot, flash the recovery and then boot into recovery. Make sure u unlock bootloader when in fast boot. Else recovery will be wiped. Also i suggest using TWRP instead of cwm.
