Help me fix my Recovery

So I was attempting to try a new rom - Android Revolution HD 3.0.0 -. I downloaded the rom, and super wipe script and booted into CWM recovery.
Ran the Super Wipe script and now it just hangs on reboot. I can still get into fastboot but I can't get into Android or Recovery. Whenever I try to boot into Recovery I get Andy with the spinning sphere. The blue loading bar hangs about 1/5 of the way across. Eventually the phone reboots and repeats.
I've tried gnex toolkit v5.6. I tried flashing a new recovery via the toolkit and I tried option 7(1-click for all). Both say they successfully installed the recovery but I still can't boot.
Any ideas?

and this is why you dont use toolkits because you dont have a full understanding of what you're doing and relying on a program.
fastboot flash google stock images OR fastboot flash clockwork recovery in bootloader mode and then proceed to go into recovery mode and wipe factory(data)/cache/dalvik and flash a rom
i advise doing the second that i suggested. if all else fails, flash google images as a last resort

Thanks for the quick reply. I just assumed the toolkit would be a quicker way of doing the commands manually. That being said even fastboot flash recovery recovery-clockwork-5.5.0.2-maguro.img nets me the exact same results, so it looks like I'm off to google stock images

It is quicker in a sense. But with every short cut that you take, you're losing knowledge. Sure, you're rooting and doing all that fancy stuff. But you're not realizing what you're doing so when you have a problem.. you're unable to diagnosis it because you aren't aware of what that toolkit just did.
Okay. Then just flash google stock images.. after it boots into Android, just fastboot flash recovery again and then wipe and then flash your ROM.

back on stock rom for now . Will have to flash custom recovery later but for now I have a working phone again which is nice.

Glad to hear it was happy to see that you didn't panic and claim your phone being 'bricked.' Definitely weird how the superwipe script caused that problem on your phone. Personally not a fan of "superwipe" that's just me. Manually wiping factory(data)/cache/dalvik is good enough for me.

Same happened to me trying to install HD 3.0. I also had to go back to flashing Google stock after getting the boot loop you described. Would it have anything to do with that script trying to format partitions to ext3??

Galaxy Nexus Bricked

My nexus is from everyway shape or form bricked. I tried all forms of fixing it:
-Tried flashing stock image from fastboot
-tried flashing stock through odin
-tried flashing through recovery
-tried locking and unlocking the bootloader
What I noticed: I can flash different kernels and mods. But as soon as I try to flash a ROM that I already had saved on the SD it cancels the install and shows "(bad)". I also cannot mount /system to format it.
Also, when I try to flash anything thru odin or fastboot, everything works according to ODIN and I get the blue "PASS" sign, but when it reboots nothing sticks. I was able to use the Toolkit v7.8 to boot into TWRP recorvery, and it still doesnt work. NOTE: I can only boot into it with the Toolkit, I cant actually flash the recovery permanently.
I guess the system files became Read-Only.
I have no ROM currently loaded so I can only boot into Download mode/Fastboot and CWM recovery.

Things to try

It looks like you've tried just about everything and you are very capable of getting it done. My only suggestion is that when I thought I was bricked, I kept wiping all the data I could find. From CWM I started with a wipe data/factory reset and that had the best results for me. After that, wipe dalvik, wipe battery stats, and I tried loading a new ROM from sdcard. I wouldn't try to install a new kernel or any other mod until you successfully boot into your new(or old) ROM.
Like I said, you probably already knew all of this but I wanted to make sure all the bases were covered. If it doesn't help you, I hope it at least helps someone else. Good luck, and please post your progress!

try using fastboot to erase the system and other partition.
fastboot erase system
fastboot erase userdata
faseboot erase boot
fastboot erase recovery
Then flash stock from fastboot

Ok, I try the fast boot method today after work. I have a feeling it wont work until I can mount the system folder which is the sole problem if Im not mistaken. I wiped absolutely everything I could in CWM to no avail. So fastboot looks like the only choice

Fastboot does not require mounting of anything -- it writes to the entire partition.

I don't have the best knowledge when it comes to this. But if this is true then perhaps I lost root? When I was flashing a Rom my phone shut off and that's when these problems started. Would losing root be the cause of this?

No. Root has nothing to do with fastboot. Root has nothing to do with your device. Root has to do with the Android build that you are running.
When you are booted into the bootloader (i.e., fastboot mode), there is no Android OS running, so how can there be root?
The fastboot executable on your PC interacts directly with the bootloader, and it will wipe an entire partition, or write an image to a partition.

first off you need to download wugfresh's Gnex toolkit:
http://forum.xda-developers.com/show....php?t=1766475
second you need to install all the drivers if you haven't already.
then you need to choose your model type
after you will need to click on back to stock what it does is it resets everything, assuming your phone cant boot up choose not booting
once that is done you can choose the factory image which can be downloaded from Googles factory images or you can use the options provided
after that you follow all the steps provided in the tool kit. the tool kit is mostly automatic so it wont take allot of time.
once that is done you are back in stock and have lost everything but don't fret because you can root it again using the same tool kit.
quick point your phone still has an unlocked boot loader so don't worry about that.
once youve completed the above steps you should be back to your good old galaxy nexus home screen

I've personally never had problems with tool kits and have found them very helpful, because of my busy schedule I don't have the time to do it myself even with my amateur coding skills, and have found only people who dont understand what there getting themselves into get bricked, thats not to say you cant brick your phone if your smart but if your smart you would have done a nandroid before flashing anything.
thanks again for that enlightening post

Help, soft bricked my device.

I was attempting to unlock/root and long story short, now I have TWRP installed, and I can get to FASTBOOT but if i try to boot normally I get the Nexus logo, and no further. When I unlocked, I installed TWRP then loaded it. After leaving TWRP it said 'Seems you are not rooted, want to root"? or something to that effect. I clicked YES and now I'm stuck. Since I had just unlocked it, it *should* have reset my entire device(which was all stock anyway) so I am not sure what went wrong. I have been trying everything I know but I'm now out of ideas. Would appreciate any help. I see now that the version of SuperSu that it would have pushed would have been wrong, would that be preventing the tablet from booting?

If you can mount in fastboot you're not bricked. You tried to check md5 and push the recovery image again? And also try to throw new ROM on it.

I would suggest you just restore your N7 back to stock. No need for root yet, seriously! But this should help get you going in the right direction.
Power it off completely. Hold Power + Volume down until it boots into the bootloader. Run the following commands:
fastboot devices (to confirm you are connected)
fastboot flash recovery recovery.img
If you haven't unlocked your N7 yet, run fastboot oem unlock first.

I put TWRP on there, immediately after unlocking. So it should have been completely stock since as far as I know it wipes it when you unlock. After putting TWRP on there, i told it to reboot normally(from within TWRP) and it detected that I was not rooted and asked me if I wanted to install SuperSu. I said yes and now it will not boot to the operating system. It boots fine to Bootloader and Recovery. And I am certain it's connected to my PC because I can even tell it ADB REBOOT BOOTLOADER/RECOVERY and that works. But I don't see how I can load a ROM onto it if I can't access it via windows. I don't know how to get a ROM onto the SD card. Surely there could be a way but I don't know it.

Start over by downloading recovery, Superuser and a clean stock rom image.
But before that you could try to reset all data in recovery (factory reset) and cache if you haven't tried.

[Q] HELP! Stuck in TWRP boot loop!

Howdy Everyone,
So just tried rooting my new m8 and now I'm stuck endlessly booting into TWRP. I thought I did everything correctly: Unlocked the bootloader, installed the USB drivers, installed the ADB fastboot drivers and then flashed twrp 2.7.0.3. I get to the the htc logo screen/warning and, bam, back to twrp everytime.
Does anyone know how to fix this??? The last time i was rooting and installing custom mods was back in samsung galaxy s2 days, so my knowledge is a little dated. Please help!!

Try flashing the recovery again. Download it from the link provided here and confirm the md5 checksum for the zip file.

I encountered this issue as well. I'm almost certain that when you were flashing recovery, you used this command "fastboot flash boot recovery.img".
The right command should be "fastboot flash recovery recovery.img".
To rectify the issue look for a tread that has the boot.img for your specific M8 model and flash boot back using " fastboot flash boot boot.img".
This should fix the issue you are having

I followed the instructions on the TWRP site:
Download the above file. Save it to the root of your /sdcard directly (internal memory only) and rename it to twrp.img
Launch terminal emulator or connect to your computer and open an adb shell, then type the following:
su
dd if=/sdcard/twrp.img of=/dev/block/mmcblk0p43
Then reboot to complete installation.
But that left me in a TWRP bootloop. Can you please give me step by step instructions on how to get out of this bootloop?
Thanks!

First off, being a noob and using dd without even knowing what partiton you're writing to is extremely dangerous.
Just use fastboot.
plug phone into PC in fastboot mode.
Code:
fastboot flash recovery twrpfilename.img
fastboot erase cache
on phone go back to hboot, select, recovery
In TWRP go to wipe, then swipe for a factory reset (Advanced wipe cannot properly wipe cache and dalvik after fastboot erase cache)
then go to advanced, select cache, dalvik and system and swipe to wipe those partitions.
then go to install, select the rom on your phone and flash. follow on screen instructions.
If you don't have the rom on your phone for whatever reason,
connect your phone, while in TWRP to your PC then, using adb on your PC
Code:
adb push romfilename.zip /sdcard/
Wait until it completes with bytes sent.
Then flash using method listed above.
Be careful if you want to keep your phone. I stress this, if you don't know what a command you are issuing does, exactly, DO NOT DO IT until you look it up and understand what you are doing. There is great risk even when you know what you're doing. There's a LOT more when you don't.

You need cwm recovery to factory reset from cm roms.
Also you need to be in FASTBOOT mode for it to detect your device.
Boot to fastboot, erase cache, reinstall twrp.

Phone won't boot into Android or Recovery Mode. Help?

32gb variant (H790).
I tried most of the solutions I've seen on this subforum so far - including doing a full flash-all.sh command as well as the flashing of individual files into my system.
So far I've been able to do so using the stock images from Google (Android N). However, I can never get Recovery to boot and my phone will not boot past "Google." (Not even the colorful animations show).
I am not sure what I can do - I unfortunately got this phone via a 3rd party and not Google's Store, so I'm not sure if they would honor an RMA request (maybe if I said it was a gift they would relent?).
I was reading this thread: http://forum.xda-developers.com/nexus-5x/help/req-help-to-unbrick-t3251740 and realized that this might be my last alternative, but I'm a bit concerned about going through all of this without giving it one more chance having access to at least the bootloader screen.
Does anyone have any suggestions on what I might be doing wrong? Should I attempt to flash the latest Android 6.0 image instead?

Is your boot loader locked? How did you flash the stock images?
Reboot into fastboot, run the flash all, reboot back to your bootloader when it's done and it. These commands....
Fastboot format cache
Fastboot format userdata
Then restart the phone

Corrupted bootloader partition, your phone is little piece of brick. EXT4 is the motive, HAHAHA.
I lost a ****ty device like you too.
Now i learned: (IF IS EXT4 , NO!)

I ran format cache and userdata (which I think the full flash also does). I am unable to go past the Google screen.

I was able to reflash my rom again too, without errors, but the **** recused to boot up or boot recovery, your phone is death like the apocalyptical beast google inc!

Can you get TWRP installed via fastboot and boot into that?

Try to flash TWRP with fasboot and see if you can boot it. There's an actual problem with the last versions of TWRP (TWRP 3.0.2-1 and 3.0.2-2), where if you backup then restore an EFS partition you end up with a phone where it doesn't get past the Google Screen (or crashes in the first frame of the bootanimation), lk panic apparently due to EFS corruption.
If this is your case (derped restoring EFS like that) and you can flash and boot on TWRP, try to flash TWRP 3.0.2-0 and restore and old backup of EFS.

maybe same problem
I have the same problem.
Before i flash manually my phone into android 7(factory image) it was rooted and unlock bootloader. I locked the bootloader again and until here everything works fine. I flashed the stock recovery mode by TWRP. after that the phone won't boot android and stock recovery mode. everything was lost except the bootloader.
I tried lots of tricks but don't answer(sideload ota update, format cache and userdata). I tried to flash stock recovery or custom recovery but i couldn't because in the process the phone restart and restart again and again. Even doesn't work temporarily boot, custom and stock recovery mode and phone has no reaction.
I only have access to the bootloader.
Would you have any suggestion?
*ps: When phone is boot up just shows a white google logo and after that shows a green bot with red alert and a message(no command) . In this point phone restart suddenly and the same process is repeated.
