[Q] What am I doing wrong?

Using the verygreen instructions I have been running CM-7.0.3 encore signed off of SD for about 2 months now and want to try to update to the current nightly.
I put cm_encore_full-176.zip in the /boot directory of the SD and tried all of these without success:
1) Used the boot select u-boot.bin to boot from sd and recovery. It just hangs.
2) Used the boot select u-boot.bin to boot from sd and alternate. It just hangs.
I reverted to the standard u-boot.bin and did these without success:
1) Booted into CM7 then using the shut down menu rebooted into recovery. The update was not applied and boot was normal.
2) From power off, held down the power on and N buttons. After loading... appeared counted to 4 and released both buttons. No update applied and booted normall.
3) From power off, held down power on and N buttons. After loading... appeared, released power button, then pressed and held it for 5 seconds, waited for the screen to blank and let go of both buttons. No update applied and NC shut off.
Anyone know what I am doing wrong? I have been scouring all of the NC root sites and it seems everyone has a different hold buttons and release sequence. Is there a special /boot folder or something that can only be accessed while the sd card is in the NC where I have to copy the update zip file?

Why you doing that?

Because there were recommendations to do to those steps on this site and others.
Do you have a solution to my problem?

You are going from a .29 kernel to a .32 kernel... From VG's SASD thread... first post... you need to update the version of the SASD.
How to update if you already installed using older version of the installer and don't want to reinstall (understandably):
•Get update zip from http://crimea.edu/~green/nook/update-genimage-1.3.zip
•Put the zip file as is onto the first partition of your sdcard..
•reboot into recovery (triggered by the keys, the reboot into recovery does not work yet).
•The new version would be installed and you are done.
•You can combine this installation together with updating to .32 kernel in one step. Just put the update-cm file and the update-genimage-1.3.zip to the first partition. Make sure there is still at least 1M of space left!

Just put the new nightly build into the root folder and boot into recovery.
The only thing you need to do is your skill to boot into recovery, that's all.
The rest should be taken off.

Ok copied the file onto /boot.
Tried a different button sequence:
http://www.youtube.com/watch?v=Kps9cWvyzqo
It still will not go into recovery mode. The thing is that I used the instructions on the video to help me install CM7 and gapps in the first place and it worked fine.
What exactly is the correct button sequence to get the NC to power on to recovery mode?
As you can see I found 3 different people saying to do it 3 different ways and none of them seem to work.
I am waiting for someone to say you have to wait until the 4th tuesday of the odd numbered month and hold down the buttons to the count of pi * the number of times Lindsay Lohan violates her probation in the past 4.5 months.
Do I need another program installed for this to work? Something like clockwork recovery mod (whatever that is)? Is there a difference that my NC doesn't say "Touch the Future of Reading" but just says "Loading..."?
It is making me pull my hair out and I didn't have that much hair left to begin with!
Just wanted to add an observation that after doing the button sequence in the video, "Loading.." the screen blanks for about .5 second and then is displayed again off center. The it goes into normal boot up.

I've had to use the "rhythm method" for the first time in a while this week, setting up my dual boot on eMMC, and verygreen's instructions were the only thing that worked for me:
verygreen said:
hold nook N key and then press and hold power until the "Loading..." message appears and then disappears with screen going blank. Release power button, then press it again and hold for ~5 seconds, the bootloader "Loading..." message should be on the screen for three seconds or so before you release power button, keep holding N button until screen blanks again. If the screen went off while you were holding the power key, that means you were holding it for too long

is what should be happening--when the message comes back, press the power button again for five seconds, then release. Anamardoll's videos were made prior to the B&N 1.2 update, prior to CM7.1's existence, and prior to any of verygreen's SASD updates, so the behavior was a little different then.
Also, you may have successfully booted into recovery and installed the SASD 1.3 update file without realizing it--small packages can flash very quickly in verygreen's installer, and iirc, the "Loading" message you describe is expected behavior for SASD 1.3. If you look at the SD's boot partition in your PC and the .zip file is gone, it very likely installed. If that's the case, Power > Reboot > Recovery ought to be working now; copy over the CM7 update .zip, attempt the rhythm method again (may as well), and if you go straight through to CM7, try Power > Reboot > Recovery.
If none of the above works, you have very likely hosed your boot sector with some of the shenanigans in your OP, and may as well format the card and start from scratch with an up-to-date SASD image.

CWM cannot help you with an SD install. If, however, you have chosen at any point to "Flash ClockworkMod Recovery" from ROM Manager, then you've already written CWM to your internal recovery partition, and might want to consider installing CM7 internally, as it would now be much easier than fixing your card (assuming none of the above got it done).

Thanks for the help all.
I am just going to redo the sd with the 177 nightly.

[Q]

Alright everyone, I have an NC that I rooted quite awhile ago to great success. However, in my quest for updating to ics, I completely deleted everything. Buttons don't work, and for some reason I can't have it access my computer's hard drive because it won't turn on.
So, if anyone has any ideas for fixing it, it would be much appreciated. All I think I need is the original NC software (everything) and a way to put it on the hdd that I can't access. Thanks in advance.

I think you should be able to make (or re-use) a CWM card and use it to install a fresh rom. Unless it's totally borked, the NC should still boot first from the SD card.

I would, but the only problem is that I cannot even get the device to power on, the buttons don't work.
Edit: Here's the deal, I just need the damned thing to power up for me so I can mount the sdcard and restore it. But whatever utility makes the buttons work, is gone - they aren't just merely broken. So I can press the buttons and the kernel or whatever it is that interacts with the buttons will not understand what is going on because the utility is not there.
If anyone has a solution for either powering it on via usb (with the device off) or getting the buttons to work again, great.

Can anybody access their NC cwm for me and try to find whatever it is that I deleted? It has something to do with buttons or what not.

Are you holding the power button on for several seconds.. Until the screen flashes?

^ What he said. Sometimes I have to hold the power down for quite a while, or try it several times. This is usually after an SOD (it may help to have it charging too).

Yes and yes. I hold it for quite awhile. Still does nothing.

Have you tried holding down the n button along with the power button?
Hold both for 10 seconds. Release. Hold power button alone for 10 seconds. Sometimes it takes 2 or three cycles of holding down both buttons, then the power.button to get the nook reset.

Just because the screen does not flicker, and you can’t access the file system from your computer using a USB cable, does not mean that the device has not powered on. I can format the whole file system, and the power button will turn it on every time. For turning on the device, the power button is independent of the file system.
It sounds like you have just screwed up the files in the boot partition. I screwed up my device to this point more than a couple times. I had the same none flickering screen, and no file system access from a USB cable. The NC is programmed to boot from a SD card before internal storage, there is really no way that you could have screwed it up to the point that it won’t continue to do that. Below are the steps that I have always taken to get back to a working device,
*fully charge the device, this is very important, because the device might have been on this whole time, and you just could not see it
*Download the stock 1.2 update.zip found HERE, get the “update-nc-stock-1.2-signed.zip” file
*Now download the file to make a bootable CWM card found HERE
*Follow the directions in that post to make your bootable CWM card, then place the “update-nc-stock-1.2-signed.zip” file onto that card
*Put the bootable CWM card into your NC
*Hold the power button, and count to 3, then let go
*If after a count to 10, nothing has appeared on the screen, repeat the last step, you most likely just turn the device off.
*This time CWM should load up, select “wipe cache partition,” followed by “wipe cache partition”
*Now scroll down to and select “mounts and storage”
*Now scroll down to and select “format /boot”
*When that has completed, you will then select “install zip from sdcard”
*Then select “choose zip from sdcard,” and select the “update-nc-stock-1.2-signed.zip” file
*If you receive an error at the very start of the install process, you need to select “toggle script asserts,” to disable script asserts
*When that has completed, remove the card, select reboot the device, and boot the device no SD card in it
Your device should now boot just like stock. At this point you should be back to a completely stock NC.
Report back with any results, good or bad.

Is it necessary to format /system and /data as well if changing between firmware?

Can't try it just yet, but after I'm done traveling it will be top-priority.

[Q] Can I root from a bugged nexus 7?

Before I begin I must say I've never used an android device in my life so this is all completely new to me. The only experience I've had was rooting and installing CM or something similar to an iphone 3gs a few years ago.
I'm aware a lot of people are having problems with their nexus 7 hanging at the animated rainbow-colored X screen. I've seen the suggestion to hold power and vol up/down to get to the restore factory default settings - but that doesn't show. Mine just shuts off. I've tried going to the bootloader screen via power+vol up/down while the machine was off but nothing ever happens. The nexus just stays powered off. Also, if I hold power while it's hanging on the rainbow X, nothing happens - it doesnt even shut off. In order to turn it off I have to hold power+vol up/down.
I have not rooted or installed any ROMs on this android yet. But I do want to. I am curious if I can somehow root and flash my nexus.
If someone can point me in the right direction on how to start this from a basically dead nexus 7, please enlighten me. I've read through a few instructional threads so far but they all start off with the nexus 7 being able to fully start.
Please advise.
Thanks!

Thanks for the link. I tried entering safe mode, didn't work
- Press/Hold Power button until Google screen shows up, RELEASE Power button
- Press/Hold VolDn until Android has booted up
The device doesn't even boot up in safe mode. Still hangs on the rainbow x.
Got into bootloader using these instructions while n7 off:
- Power+VolUp while booting to enter recovery
- You can release buttons after you see Google on screen
selected Recovery.
It turned off then on, showed the Google screen, and now shoes an android fallen over with "No command." shown underneath and am continuing..
edit: wiped and restarted. can now finally root. thanks bud.

[Q] Dell Venue 8 Pro Recovery corrupt

Due to my own actions (idiot) I deleted the recovery partition to try to regain 9gb it took from me. I would like to reformat and start again but I cannot. I have tried the following dell advice:
these are the steps to reset your tablet:
1. If your device is not turned off already, hold the power button for 10s to power it down.
2. Once it's powered down, press the power button to turn it on.
3. When the Dell logo appears (you may have to do it as soon as the screen turns on instead of wait for the logo to appear), hold the power button again to turn it off.
4. Do this process 3-4 times (they said 4, but it was only 3 for me) until you see something at the bottom saying that it's starting automatic system repair.
5. From there, you should see a menu. Choose "Troubleshoot", and the next menu should ask if you want to reset your PC along with some other options.
6. Choose reset PC, and when you get to the two options that ask "just delete files" or "fully reset PC", choose the second option. From there you should be able to follow the instructions to setup your device.
When I get to restore it asks for system files? I have tried the Dell recovery but that fails as well.
I have made a boot disk on my USB via an OTG cable which is recognised by the tablet, but it refuses to boot from this even after setting the bias to 1st boot from the USB.
Can anyone advise me of how to solve this problem and reformat and start again.

I only can reach the Bootmenu. Bricked? What can I do?

Hi,
I'm not very experienced with those root things and followed a tutorial to do so.
I unlocked the bootloader, had TWRP installed and root. This worked. Now I wanted to remove Root and TWRP and go back to the original state. I couldn't find the stock recovery file, so I installed the P996A04V1.3.0B13_MR2_sd_ssl.zip via TWRP from the SD Card. Till here it worked. I could enter the stock recover and boot the phone.
Then Android wanted to install a security update. I allowed it and this is where the problem started.
The install process stood still on 25% for minutes. I thought it stuck and pressed and hold the power button to reboot that I can wipe the memory. But nothing happened. But the installation Process continued suddenly. I had the feeling that this power key worked like a skip key. So maybe it didn't install a file where it was stuck.
After the installation reached 100% the screen switched to black and nothing worked anymore. I couldn't restart the phone or anything but I think the phone was doing something cause it consumed electricity. When I checked the phone hours later I noticed it was empty.
I can reach the unlocked bootloader now, but none of the selections works. Doing nothing to boot or select Recovery lead to black screen and stuck. Then I have to wait until the battery is empty again. Fastboot, Power Off just restart the phone and I end in the Bootmenu again. I can't even fully charge the phone. As soon as it has enough power to start the Bootmenu appears. So I don't see the display of the charging process.
I don't understand how this could happen. I tried different key combinations when the phone had enough electricty to start. The phone always restarts and end in the bootmenu. Only when I press all three keys it's standing still on the ZTE Logo screen but as soon as I release the keys I end again in the bootmenu.
How can I force another Update?
regards

Let' start with the basic questions:
Do you have proper backup of your data?
Which Android Version did your Axon had before it went unusable?
You could try to reflash TWRP.
Boot your phone into bootmode.
Download a proper TWRP Image on your PC (https://forum.xda-developers.com/axon-7/how-to/download-center-factory-images-ota-t3606547)
Open a cmd shell (press the windows key and type 'cmd' -> press enter)
Navigate to the folder where the TWRP Image is stored ('
Code:
cd C:\Users\[I]YOUR_USER_NAME[/I]\Downloads\
')
Type: '
HTML:
fastboot flash recovery [I]TWRP_IMG_NAME.img[/I]
'
Afterwards you could try to reboot into recovery mode.

I don't have a backup. But there isn't something imortant on the phone that I want to keep. I can do a full reset and reinstall, too.
Android must have been the latest offical availabe what's in the file. Was it Android 8? V1.3.0B13
The fastboot mode doesn't work. The screen turns black and the LED blinks red but only for a moment. Then the phone restarts and I'm in the bootmenu again. Windows doesn't recognize it as device.
Is there a way to force it to do an update from my SDCard without it needed to be connected to a PC?

I don't know of any.
But you could boot into EDL Mode (Press and hold Both Volume button and then press the power button) and flash a Stock EDL rom from the Download Center i have linkd before.

It's not visible for the PC. The only thing I see is the charging screen when its total empty and you can't even boot as. As soon as it has enough power to switch to the normal screen the bootloader appears and when I do nothing the screen turns black and nothing happens. I don't even know if it is charging. The LED is off.

Follow this guide to unbrick it and then use MiFlash and flash an EDL ROM
