Can't go into recovery mode, help?

when I boot my phone up, instead of the htc and boot animation screen it stays a black screen, Whenever I try to back up my current ROM or Go into recovery mode the screen goes black untill I take out the battery and reboot, what could be causing this problem and how could I fix it? Like I said I can't get into CWM so a wipe is out of the question, and adb isn't an option right now, please help

Are you able to get into your bootloader/hboot screen (hold the power button and the volume down button)?

You should stop bumping this thread. Nobody is posting in this forum so you don't have to worry about your thread being lost...
Similar thing happened to me, but I could actually get to the HTC screen. What you need to do is set up adb, and get to your bootloader by holding vol. down + power and start fastboot usb. There is no way to fix an issue like this if you can't use/get into your recovery. From there you can try fastboot erase system -w and then fastboot flash recovery [name of recovery] and then fashboot update [CM7.zip]. Clockwork mod recovery can be found here: http://wiki.cyanogenmod.com/wiki/TMobile_G2:_Rooting

i would but now my phone is deciding not to connect via USB, i think its falling apart, maybe time to get a new phone i guess...

Wait, you are able to boot up normally?
If so, use flash_image recovery recovery.img to flash CWM again.

From within your rom you need to download the CWM recovery image and save it on your SDcard. Name it recovery.
Use terminal emulator and type in:
Su
Ls sdcard
Flash_image recovery recovery.img
This will flash the recovery back you your phone

Assuming you've tried to flash recovery from ROM manager (Choose "Flash ClockworkMod Recovery" within ROM manager), if not - do that.
Otherwise, try this:
Download this: http://download.clockworkmod.com/recoveries/recovery-clockwork-3.0.2.4-vision.img
rename it to "recovery.img" and place it on the root of your SD card.
Use terminal emulator on your phone, and type the following 1 line at a time:

That's a good thing. Now try rebooting into recovery from ROM manager. I'm a bit concerned that you can't get into the bootloader, I smell a bigger issue.

[Q] How do I get SU back? I broke it...

After flashing a JB rom and a corresponding JB Super SU zip this morning, I accidentally uninstalled the Super SU thinking I had a different SU app already. Turns out I didn't, and now I don't know how to get it back. I flashed the SU zip again in recovery, didn't work. But now nothing requiring root access works, so I can't even get back into recovery as far as I can tell. What do I do to get root back?
UPDATE: No matter what kind of weird things you may have done to your GNex, if you happened to have screwed up your SU abilities somehow, these next few posts will most likely help to guide you. I screwed mine all up to hell, and these guys helped me remember what was going on and what to do to fix it.

Reflash the ROM.
Try getting into fastboot, through the volume and power keys when the device is shutdown.
Happened to me before, that was the only solution.

you can download the superuser app from the market

I DID IT AGAIN!!
I didn't learn my lesson, and kept screwing around with the super user apps, and I ended up removing the super user binary. (what is wrong with me?) So this is a little more serious... Now what do I do?
I'm not a noob rooter (rooted my OG Droid 2 years ago and kept up with development, now the same with my GNex) but I guess I somehow got around having to deal with SU issues the whole time.

That's all I use, but I can't get to recovery. I'm running stock JB rom, so there's no option to reboot into recovery from the power menu, and since I don't have super user, no app can get the permission to reboot into recovery either. I can power down and boot into the bootloader (or whatever that is) holding the volume down and power buttons, but I don't see how that helps.

if you can get to the bootloader, scroll using the volume keys to get to 'recovery mode' and select that. that is recovery and you should hopefully have CWM or TWRP still installed.

Once your at the bootloader, you should have the choice to boot from there into recovery, though it's been a while since I've done it that way so cannot give you the exact steps. You should be able to use the volume keys to highlight the recovery option and then press the power button to choose it, I believe.
But you may have lost CWM, since JB could have over-written it. If so, you'll need to use fastboot to re-install it, after which you can use CWM to apply an SU zip from your internal SD card.

Thank you blowtorch, Zepius, and high vista! It was having both vol buttons pressed that I had completely forgotten about. That solves the problem and dams up a flood of questions that could have been had I not gotten that minor detail in.

Do you know what version of CWM you're running? There were a few versions that hung on the 'htc' screen and would take a few reboots to fully boot.
Sent from my HTC Vision using xda app-developers app

If you can get into hboot , or able to see 'adb devices' show your device you may be able to type:
adb reboot recovery
and cause it to reboot into recovery from your terminal if you are finding difficulties with using the button method.
The splash is sometimes indicative that you don't have a rom installed at all (i.e.: if you did a clean wipe and such), but worse case scenario, you don't have recovery installed either in which case you may have to install it via fastboot (at the bootloader screen)

can you give any link to do that or something else.. i really need it. im newbie dont know anything

and i use android speeddaemon fantasia rom..

adb (android debugging bridge)is an executable program for a pc (or linux or apple) to communicate with your android phone. it is unlikely adb will work if you cant even access your hboot but you can try.
if you rooted your phone yourself than you should have the drivers installed and adb.exe also installed on computer, along with knowledge on how to use it.
if you didnt/dont have it, google android sdk for the package, and google adb for dummies (or something like that) for more instructions if the sdk doesnt provide you with enough.
but like i said it is unlikely to work and if you want any chance of fixing your phone i suggest logging onto freenode to get real time help

anyway thanks.. i have resolved my problem with battery pull first and then press vol down + power button

If that was your fix, you most likely have the buggy CWM version. Update your CWM recovery to the latest version or flash 4ext recovery (which I've never heard of hanging like that)

[Q] Unable to restart in CMW recovery

I try to root my phone samsung SGH-T999V s3 of videotron. I use the method of this post: SGH-T999V Canadian GS3 (CWM + ROOT + CM9).
I had to redo the step with Odin 3 times to finally restart the CMW recovery. I remove the battery and finally I succeeded. I install ClockworkMod touch.
Now the problem is that I am unable to restart CMW Recovery mode. I tried the method of Vol + and Power Menu and the method by writing terminal emulator su, boot recovery and also ROM manager. It does not work.
Each time it is the stock android recovery which starts
I do not know what to do to install CyanogenMod 10.
I have read many post but I do not know if my phone is compatible with the other method.
Can you help me please

Reflash and take the battery out faster. ODIN will say it's succesfull and then the phone will overwrite it so the only way to know for sure is when you go into recovery.

Battery pulls are unnecessary. Delete or rename these.
/system/recovery-from-boot.p
/system/etc/install-recovery.sh
Reinstall recovery with rom or goo manager and reboot recovery.

Ok, you do need root first to delete those files. Sorry for misunderstanding earlier.
Reflash your recovery with odin like before but make sure you uncheck suto reboot.
After complete, unplug and hold the power button untill it begins restarting. You need to be quick but as soon as the screen goes off, immediately press home and volume up while still holding power. Itll take a few seconds but after the blue text flashes at the top of the screen let go of power but keep holding the other two till you get recovery.
Now flash superSU or superuser and reboot.
Now you should be able to delete those files and reinstall recovery with goo or rom manager.
Im going by memory so you may want to get another opinion first. But I think you should be good.

There isn't an option under settings --> developer options for root? At one time, they had didn't options for apps, adb, or both. You would need the both box checked for it to boot into recovery via an app. I haven't used it in a while, so I'm not even sure if they still do it this way.
And it is strange that you can't boot in recovery. Instead of the power off, then hold volume up, home button, and power....have you just tried to reboot the phone and when the screen goes blank hold the volume up and home? I've had luck getting into recovery by that.
Plus, if you are running CM, there should be a reboot option for recovery when you power off. Reboot --> recovery.
Last idea, have you tried to download goo manager from the market? That works well with TWRP.

I tried goo and that didn't work.
Cm does have the reboot options, but it had to be turned on. Developer options doesnt show up under settings, but I remember there was a way to turn it on. I went under "About phone or Device" clicked on everything like 10 times and I forgot which 1 it was, but I unlocked developer options. Turned on reboot menu. Rebooted phone into recovery and although it took a while I got into recovery. Flashed a new rom and I'm back in action.

Thank u guys honestly. I could not have done it without u guys.
