My Nook HD+ bootloader won’t launch the installed OS, CM 13. The Nook screen appears, and then gives way to the Cyanogenmod Universal Bootloader. After a bit the blue android image appears. It pulses normally at first, then the pulsing pauses, and finally the process starts all over … and over, and over, and over!
At first I thought there was a problem with the OS, so I booted into recovery (TWRP 3.1.1-0) and tried to flash CM 13 for ovation. That didn’t work, so I tried flashing other ovation ROMs. None will install. They all report an ERROR 7. I’ve attempted to work around that error, but none of the methods I’ve found made any difference.
It seems that I may have to reinstall the factory/stock ROM, and I’m okay with that. But it seems I can’t do that either. The stock rom download is in a CWM backup format, and I have TWRP, not CWM. So I tried to flash CWM with TWRP, but in order to make that work one has to reboot into recovery via TWRP, The problem here is that the TWRP boot menu has just two options … System and Power Off. The Recovery option that is supposed to be there isn’t!
So I tried to replace TWRP with CWM via ADB. I can sideload a CWM zip without a problem. I then issue an ADB Reboot Recovery command. But, instead of rebooting into recovery, the bootloader launches instead. As a result, when I go into recovery it’s still TWRP. I’ve also tried powering on with the CWM bootable image file on an sd card, but no matter how many times I power off and back on, my tablet never recognizes that the file is there and my problem persists.
Is there a way to boot into CWM or swap CWM for TWRP in a situation like this? I’ve seen postings that suggest fastboot may the be solution, but that requires that debugging be enabled, and it was not enabled when my problems began. Apparently there is no way to enable debugging without launching the OS.
Help!
Update:
My Nook HD+ has not rewarded my attempts to bring it back to life Perhaps I’ve made things worse. I certainly haven’t made things better. Here’s the latest.
When booted up, little or nothing has changed. At bootup the Nook screen is followed by the Cyanoboot Universal Bootloader screen. Sometimes it gets no further, and reboots. More often the android image appears with a halo pulsing in the background. Sometimes the halo pulses a couple of times before the device reboots. Sometimes is pulses a bit longer before rebooting. Sometimes it never stops pulsing (until I press and hold the power button to shut the bloody thing down, that is).
Thinking the problem was related to the OS (I had been running android 7.1.1 (an unofficial HD+ release, but from a very reliable source), I've tried in vain to flash another OS. I've tried multiple android releases, from 7.1.1 down to 4.4.4. I've also tried flashing several versions of the HD+ factory stock OS. I’ve done all this using TWRP, and also by booting CWM from an sd card. No matter which recovery I've used or which OS I've attempted to install, the process always ended with an ERROR: 7.
So, I got my hands on a good Nook HD+ running android 5.1.1. I made unbundled TWRP backups of the System, Boot, and Apps partitions using release 3.1.1-0. The System and Boot partitions each restored without a problem. The Apps would not restore, ending with “extractTarFork() process ended in ERROR: 255." That error probably isn’t related to my problem, which is that I can’t get the system to boot up. More telling is the fact that after successfully restoring the System and Boot partitions using the backup from a good HD+, when I power up the device appears to be launching 7.1.1, not 5.1.1. The android image displays in portrait mode on the good HD+ running 5.1.1, but displays in landscape mode on my HD+ ... and the boot loop continues, of course.
At this point, at the $7.25/hour minimum wage rate I’ve spent enough time that I could have earned many times the original cost of the HD+. So, am I giving up? HELL NO! Now it’s personal!!
My HD+ boots into TWRP flawlessly, so I still have that going for me. My HD+ is not rooted and did not have USB Debugging enabled when it crashed, so any solution requiring SU or flashboot is a non-starter. Otherwise, I’m willing to give anything a try. Maybe I should be looking for an exorcist?
Thanks for reading this, and for your suggestions, words of encouragement, and expressions of sympathy.

Here's my situation, maybe someone will find it interesting or know what's going on. I was running the EOS Jelly Bean (EOS-tf201-20120728-31.zip). Everything was running pretty well for a few days, then yesterday the device simply powered off. When I rebooted it got to the splash screen then shut off before it could get any farther. I figured it was a power issue, so I plugged it in and charged it for a while but get the same response. Around this point I started to get suspicious and tried to boot into recovery. It got to "Booting Recovery Kernel Image" then powers off the same way.
So then I proceed to go into fastboot and fastboot works great no power offs. Through that I am able to flash openrecovery-twrp-2.2.1-tf201.blob and the virtuous packaged boot as per this thread http://forum.xda-developers.com/showthread.php?t=1773280 as well as factory reset. I also tried a few other boot/recovery combinations and was able to make it into recovery. In twrp recovery I was able to install the latest Virtuous rom which got me back to stock and I thought good case closed. I even made it all the way into the OS and was able to install apps, wifi worked great, run the apps etc. Eventually the screen went blank though and I was stuck back in the same shutdown on boot scenario as described above. Now I'm able to fairly consistently flash openrecovery-twrp-2.2.1-tf201.blob, reboot, get into teamwin recovery, but now even that appears to be randomly powering off.
So now I'm guessing that it may just be bricked and is probably a hardware issue since the reboots appear so random, the unit was refurbished. At the same time I'm still holding out some hope that it's simply some boot code somewhere that was corrupted and I can flash something and get things back to normal again since I can still access fastboot and occasionally ADB and recovery. I've flashed from fastboot system/recovery/boot, any other thoughts or potential combinations I could try? Also anything I can do with those tools to debug it further and get more data on what may be the root cause?
I'll put the question first for those not wanting to read the details.
I cannot get into CWM (internal) on my 16GB nook tablet. I can boot to CWM (external), but nothing works. When I try to activate ANY menu option, it takes me to a blank screen with the CWM hat logo in the background. Pressing power returns me to the main menu. Not even "reboot device" works. Can someone help? (I want to do a backup before i flash a JB Rom (internal), and to flash a JB Rom)
Now the long part:
I purchased and rooted my NT in December 2011 (about the 21st) using the snowball root (incase you are not familiar, as I don't see any post about it now, it was a modified zerg root borrowed from Albert's root method that with one menu option allowed rooting, recovery, and removal of certain nook apps and the addition of your choice of three launchers). I used it successfully on three nooks within a month or so, but this is the only one I did the complete nook removal option to.
Root works fine, but debug does not. When I run the NT hidden settings app to turn on debug mode, the developer options are listed twice (one compete set followed by another), this did not happen until after rooting, before they were only listed once. The bottom set was correctly checked to allow debug mode, and its how I rooted; however titanium backup says debug is not enabled every time I load it. (No complaints from RTB Pro) So I go into the developer settings and found two sets, the top one not checked... When I check it I get the pop-up warning, if I uncheck the bottom one, then debug does not work, if I check the bottom one I don't get the pop-up warning. With both checked, adb works, otherwise it does not. It had been this was since December 2011, and has not really prevented me from doing anything, although as the pop-up warns somethings may not work (converting apps to/from system, merging system app updates, restoring system app backups) and cause titanium to hang, but after a manual force close of titanium, most of the time the change was successfully completed.
Now, moving on one day I was being up my phone and thought "I can't remember the last time I did a nandroid of my nook" so I used RTB to reboot into recovery, the nook booted right back up into android, no errors, no different screen than a normal boot (with the nook --> hack logo, which incidentally takes about 12 minutes to boot every time, not sure if that is normal). So I tried an adb reboot recovery, but adb said no devices were attached. I went back into NT hidden settings and due enough debug was unchecked on the top, but still checked on the bottom (I've learned it lose it every reboot), do I rechecked it, got the pop-up, and went on my way. Adb reboot recovery also restarted my nook back into the OS, not into CWM.
I started to think that I may never have installed CWM, so I checked the root package I downloaded and viewed the script, first thing it does its copy the recovery image to the device, even before rooting, then installs it right after rebooting, post root hack. I thought maybe the posh was bad flash, so I searched XDA, downloaded a newer CWM, and manually adb pushed it to the phone and dd it per the instructions in the XDA thread. Reboot recovery, still nothing.
Please note I CAN get the factory reset screen to show up, but really don't want to try it without a backup, as I've been using my nook like this for 12 months and only have a titanium backup of the apps.
So I made a CWM SD from the NT thread here on XDA and booted to it :-/ intending on flashing 6.0.12 CWM to the internal emmc, the recovery on the SD was 5 something and none of the menu options worked, as mentioned above pressing power while any are selected gives a new screen with the background image, but no options. Pressing power again takes me to the main screen (same thing when selecting reboot device).
So I found a newer CWM SD package on XDA and swapped them out, this time a newer version 5.5.x, no change in how it works, so downloaded 6.0.12 and renamed the recovery image file and booted the SD. Small change this time (beyond the new version number and the option to power off, which also does nothing), when pressing the power button to select a menu option, the screen refreshes, but continues to display the same menu choices for all options in the menu.
I have also tried pushing each of these recovery images to the device and using adb to dd them to the recovery partition. Three nook will only boot the SD clockwork image.
Yes I made sure to select internal images for dd to the nook and external images for the SD.
So last night I installed nook tab recovery flasher, it said it successfully installed, before I clicked yes to allow it root access... the pressed the reboot recovery button, no good. So I downloaded and installed goo manager from the market and had it flash TWRP, same thing, reboot recovery ignores it.
Now to repeat my question, anyone have any clue how I can get recovery working spp I can make a nandroid and flash a JB Rom? (I know I can make a backup using adb, and Iam pulling one now, but I am wanting a recovery (that works) on my nook.)
Also, I am willing to try an adb push install of the Rom, I think I can make it work (although Ihave never tried it, on any device, I might be able to do it without further help), but I do not see how a new Rom will make any difference on my recovery situation and if I screw up, it would be comforting to know I had a working recovery at least.

For selecting an option in recovery is N button not power one

Your question belongs in Q&A with all other questions and not in development. Only work being shared belongs there.
Thanks

Caught that, and was able to flash CWM 6.1.15 (emmc) from the SD; but still cannot get to it.
Power+ nook= regular boot
Power+ vol up+N= regular boot
Power+ vol up= regular boot
Power+ vol down+N= regular boot
Rom toolbox pro reboot recovery = regular boot
Adb reboot recovery= regular boot
However, using goo manager to reboot recovery works, sort of...
I get the cyanoboot screen, hold N, use the menu to get to emmc internal recovery and I get CWM.
Now the problem starts about 3-7 minutes later (have not tried timing it, but it seems to be the exact same length of time each time), the nook reboots, don't matter what I am doing, using it, creating a nandroid, adb push or adb pull out apparently flashing cm10...
I decided to try a flash of cm 10 from a 11-28 build with multi touch firmware for 10 points. All was good, but I had to step away for about 2 minutes... I sneaked a peek and all was well, then when I got back my nook was on the "read forever" logo and has now been that way for 20 minutes. I checked the updater script in the Rom and it does NOT have a reboot command at the end.
I'll give it another 20 before ring to get back to CWM with out goo manager...

So, no change. Hiding the power button shut it off, I also tried plugging the usb cable in to activate boot, this causes a regular boot, which at this tinge never gets to "nook" but stays on "n" "read forever" which makes me laugh as it is currently the only thing I will "read forever" until I fix it.
Next up is to try to flash from an SD.
Update to my update
Booted from the SD, wiped everything three times, flashed the Rom, rebooted and ended up with TWRP, multi-touch and JB. Reinstalling apps through the market now, hoping previous issues are gone.
Hello,
I own an Android tablet KO PARA1 FULL and experiencing a strange problem. This is a chinese atm7029 quadcore tablet (16gb, 1gb ram, without bluetooth, only wifi, bu supports 3g dongle), running android 4.1.1 nad 3.4.0+ kernel, which came prerooted. After some time I've decided to install backup programs on in to make a full backup of the device for the case something would go wrong, and after some trying I descovered, that there is something like recovery for that purposes which seemed a good solution for me. I decided to install CWM, which I managed to install without problems and made some backups on my device. Everything was fine, I did some factory resets through the time, some restoring processes from my previously backup states of the device, was always able to activate CWM recovery menu through Reboot to recovery or through combination of Volume down a Power button...
Until last saturday. I was normaly surfing the internet, reading mails and afterwords I powered my tablet off (it is draining battery in sleep mode, but its another story..). After a while wanted again to write a mail, so I powered it on. In that momet seemed the screen too dirty for me and I tried to cleen it little bit throug the bootup process. Unfortunately I obvious confused the system with it and after boot it was not responding properly. I did not wait enough and after a while powered it off with power key pressed for a long time, to make a new boot.
But when I powered it on again, it stayed stuck in boot logo and did not boot at all. I've tried a copple of times to boot it again with no cuccess, stayed stuck in boot logo for more then 10 min...
Afterwards I decided to make it boot up with the help of computer. I downloaded adb and drivers and somehow managed to make it boot up. I thing I was too excited to see it boot up again, that during boot up process I desconected my device from computer...
My worries were reliesed and I thought it would be a good idea to make a restore from backup to prevent some strange behaviour, so wanted to boot into recovery, but nothing had happened. After some repeated clicks on Boot into recovery button, as well as app called rebooter with nothing happening, I decided to try it out through button combination. It has not worked as well Next try was to reset to factory settings. But when I go through the menu, I can click on reset to factory settings button, seeing warning that I will lost ma data, then I can push the button to make it happen, but nothing is happening. I see only the screen with the button, can touch it 100 times and the tablet stays on, fully funcional. making no factory reset as it done before.
I did a lot of reading and searching, but have not find answer for my problem. I flashed recovery images from my backups (using flashify, flash gordon, adb shell, terminal emulator), from all previously functional states of the device. I refleshed the CWM recovery downloaded from the internet for my chipset, which previously did the job just perfect, with no success...
I am still not able to reach recovery menu. For me it seems like the bootloader would be locked, but I did not find the answer how to unlock it without to be able to start in some recovery state to use fastboot command to unlock it.
Otherwise, my device is functional, still rooted, i can use it without any other problems. But not be able to do recovery from my backups, even do a factory reset.
How can I restore my access to recovery mode? Is it somehow possible?
Hopfully it is not too much information (tryied to follow the intructions and wrote everything I thought would be important to know about) and you will not be bothered to read all my story and pull me out of my darkness with helpfull suggestion.
Thanks a lot in advance

Hello. My name is ford, i have a galaxy grand prime with no current OS on it. this is because i was attempting to install a custom ROM onto said phone and the video i had watched, had me go into twrp, (which i had installed previously) and wipe the internal storage. ( i had used odin to flash onto the phone). I then god a custom rom, lineage os i believe, and attempted to install with twrp, but a good 75 % of the way through, no matter what, the phone would reboot. this happened with multiple roms i had tried, all ending with the same result, with the phone still having no os. i then thought that it might work with cwm instead. so from there, i had installed cwm, also with odin, with twrp still installed. i figured cwm would go ahead and either become the default cstom recovery, or it would just replace twrp altogether, but then after i had rebooted and put in the key combination for the custom recovery, it would still show the text in the top left for twrp, but then the screen goes black. I had turned the phone on and off multiple times with the same result every time. i don't know this is because the phone may be confused as to which recovery to boot into, or some other alternative reason, but it will not boot into anything now, just a black screen. I still know the phone is on, because it is noticeably lit, like it is just displaying a black screen. Now to the reason for my post, (if that wasn't enough), i then just tried installing my roms with odin. and no, there is nothing wrong with the roms, as they are all tar, and are all valid, but whenever i attempt to flash any rom, the little debug will say "file analysis" and then a second later crash. (by crash i mean windows will has it has stopped working). As i have said this has happened with all roms. It doesnt matter what order i do the steps in (plug in phone, then load files; load files, then plug in phone etc...), and i have reinstalled the c++ redistributable to make sure i have all of the dll's, but absolutely nothing is working. and no it is not because of the versions of odin, because i have tried multiple. So honestly im just aggravated now. Am i just stuck with a phone with no os now, or what? Seriously will try anything. PLEASE HELP
So mom dropped off her old Xperia Tablet Z SGP311 as a "gift". It did not work for her anymore, so if I wanted it and could fix it then I would have another tablet in the pile.
Her description of what did not work was what you would expect from a non-techie aka "some error turned up but I cannot remember what the screen said, so can you fix it?".
In the beginning I thought the problem was the common USB/charging problem, however I feel anything about this tablet seems different than other Android tablets, so after finally managing how volume buttons along with power buttons work, I could rule out it was a charging issue.
Getting the Tablet to boot it seemed that it had been updated and was booting into OS doing the "optimising applications 1 out of 258". However going to the step "starting applications", then tablet would just reboot a few times and then start over with optimising applications, starting applications, reboot and repeat all over. So some sort of bootloop.
I then used Sony's Xperia Companion to repair the tablet from fastboot (volume up + power) which succeded until it should reboot the tablet, then I was stuck in the same loop as above.
After a few tries I then managed to unlock bootloader and get TWRP 3.2.2 booted onto the tablet (booted NOT installed since I have no root).
With TWRP I tried deleting Dalvik cache etc., which did not help the situation, same bootloop.
With TWRP I then gave LineageOS a shot, but LineageOS experience kinda the same bootloop (both LineageOS 14.1 and 15.1).
LineageOS boots fine and proceeds with the fresh install questions (region, timezone, Internet access) but as soon as I hit next on the "Location Services" page the tablet will reboot.
Since this tablet has no value to me, I have tried deleting all data on all partitions from TWRP, I have checked the filesystem with e2fsck on the tablet which shows no errors, but in any attempts it simply reboots at the same stage every time.
So are we at the level where this might be some internal hardware failure (GPS/WiFi chip, NVRAM)? Or is there any suggestions of what else to try other than throwing this to recycle bin.

probably memory problem either RAM or ROM.
