I have read dozens of "stuck on boot screen" posts and there is nothing I see that tells me how to boot into recovery when there are no options, just a logo that freezes after 5 loops or less. I just installed Bumblebee, assumed complete data and cache wiping (possibly didn't happen) before installing the rom. I do not have anything that I know of to assist me in other options other than the dead end I am stuck going to. Is there something I could install on my SD to wipe my phone and go back to factory rom...etc etc? I would really appreciate some help!
I am using a LG Optimus V
Instead of guessing.
1/ Install Android SDK (kindly Google it). Use the EXE to install.
2/ Connect your phone via USB cable, type
Code:
adb logcat
into command prompt and paste the part where the phone is stuck here.

Well, if there is boot-loop as he sad, logcat will be really huge and there is possibility that is wont's say anything.

Anyway I'm not sure where problem is. If it is ROM related, than logcat can help, but mostly it is better revert to old backup (at least for sb. who don't know too much about unix, adb and so on). In this case is better switch phone off, press end keep pressed Home + volume down + power and wait until custom recovery will start. (you didn't mentioned if you tried this "combo")
If it's bootloader/recovery related, you can try restore your recovery by these how-to or as last chance of repair use of KDZ (my signature).
If you really wants to revert to original FW, you have to use KDZ or original LG tool if it will work.
Try to do hard reset:
# Turn the power off. If your LG Optimus One is frozen, pull the battery out and reinsert it
# Hold the Home and Volume Down button
# Press and hold the Power button until the device turns on

Bumblebee is custom ROM, isn't it? If yes, than he should have custom recovery and hard reset will not work. And if Bumblebee is something different like app or theme I must look like ididot.

haha...as hard as I tried to find the answer, it was as simple as holding down a few buttons. I hope this post will make it easier for someone to find the solution.
I really appreciate the help everyone...in a time like this, a helpful hand is beyond words.

Yeah, you really didn't know that? Read my n00b dictionary (signature) definitely. Even it is for people who wants try "something more" it brings more light about to your phone.
At least, now I know what I should add also
I have a KLU by Curtis model # LT7052. My Nieces got a hold of it and now cant get into device. Does anyone know how to possibly get into recovery mode to reset the device and just start fresh. any help with this is greatly appreciated.
idk if bumping my own thread is a no no, but i really need help with this. ive been searching for about 5 hours now on how to fix this issue and im coming up with nothing. possibly going through adb but i need to know how to connect the device to the computer to get adb. thanks for any help in advance.

Usually booting into recovery involves first turning off the device, then powering on the device while holding a combination of keys to boot into recovery mode. While this key combination is different for each device the most common combination is holding the volume up+power button simultaneously. Once in recovery use the volume up and volume down button to navigate menu selection and power button to select. Navigate to the "factory reset" option and select it, once it finishes select the "reboot system" option, and you should have your tablet reset.

Hey Guys,
Is there a way to shut the phone down straight from the recovery? I know you can reboot from the recovery into the OS, but that gives me second partition Link2SD problems, which results in various settings such as all my account and sync settings being reset, which is a pain to set up. Is it possible to press and hold the power button on the recovery main menu after you have completed all your operations so that it shuts the phone down without rebooting? Or is this harmful to the phone? What about a battery pull at the main menu so that is shuts down after you complete all your operations? Thanks in advance.

If you are using TWRP v.2.6.3.0 (touch) then under the main menu; you will find "Reboot" choose it, this will open the "Reboot Menu" there is a choice "Power Off":good:

If you have a removable battery, you can always yank it out. Just make sure that Recovery has finished whatever it was doing...or bad bad things can happen.
Thanks guys. I am using clockworkmod on my LG optimus 2X so I will be able to give the battery pull a try. Unfortunately clockworkmod does not have the power menu.

PLEASE PLEASE PLEASE.......this is my first post but I have spent ALOT of time reading on here and i dont know where to go from here....I bought my nook Tablet from a friend and it came stock with 4.4.2. KIt Kat and somehow my son got my SD card that had my recovery and back ups on it and well to make a long story short, I went through a few endless boot loops, ROMS, sleepless nights on XDA and just about anything you can imagine untill it hit its 8th consecutive "loop" and here we are......biggest problem is though that I cant get into admin account on my computer sooooo....short of having to find a friends house to drag my kids off to to fix "Mommies toy" I really need some help if at all possible. My computer doesn't read this "new" nook because it was an Android the other day and I know what it feels like.....it was pretty hard having to wake up to a TOTALLY STOCK Nook from a 4.4 with TWRP and Paranoid Android.
Ps....if nothing else if anyone can point me in a real direction to reset my admin password on a HP running Windows 7 that would be great also, I would factory reset it but the settings require the password....its pretty crazy....Thank you in advance
Noob Mom :fingers-crossed
Does your SD card contain the CWM recovery and ROM backup and is still intact?
If so then you should be able to boot off the SD card into recovery (by inserting a powered USB into the NT while it's in power-off state) and and restore from back up.

Please forgive me but tell me exactly where and what I need to look for to make sure, I have a wifi file explorer opened up on my nook because I cant re-install the drivers on my Win7 pc because of the stupid ADMIN password. So can i just add\delete\move....whatever files necessary around to make it work or am i going to have to be able to connect it to my pc?? Also, when you say for me to just restore from back up, how would i do that because i cant seem to be able to boot into anything except Factory "N".
The process for restoring from SD card using SD-based CWM recovery is as follows:
Put the SD card into the NT, and boot from its power off by inserting a powered USB cable. Press and hold the N button as soon as CyanoBoot comes up to get the boot menu to display. Use volume up/down buttons to navigate, N button to select, and Power button to return to a parent menu.
Select "SDC Recovery" to load CWM recovery.
Select "Backup and restore".
Select "Restore from SD card".
...
Select "Reboot".

Hello everybody,
I bought the Nabi 2, as refurbished, for my little child and from the beginning I am having problems to turn it on or wake it up from sleep. It is not rooted, has everything stock and I have also applied all available official updates (OTA).
The problem is to turn it on, both from sleep or from powered down state. For example, being in sleep mode (display off) for a few hours, to wake it up I have first to press the power button for about 10 seconds, than release it and press again until... the start up Logo appears, as it was completely shut down! Maybe through pushing the power button first time I turn it off unintentional, so the second time it has to power up and load the OS? But just pushing the power button shortly will not wake it up at all from sleep mode... Is this a known problem and is there a solution for it?
Thanks in advance for each advice!

The only semi known issue I have seen is when you put the tablet to sleep and it's charging. In some instances the tablet will lock up at some point after going to sleep. When you try to wake in up via power button it is locked up. When you hold the power button for 10sec you are hard powering it off and then it reboots. If yours wasn't charging then I haven't read much about anyone having a similar problem.

Thanks for your reply, aicjofs.
In my case it happens always, no matter if charging or not... and it's annoying.
Would rooting and installing a custom ROM solve the problem? If yes, is there a custom ROM dedicated to kids, similar with the stock one?

I'm still struggling with the random problems on my Nabi...
Is it possible to check the integrity and/or health of internal memory, find and mark bad blocks, etc. using a computer (Windows or Linux) connected through USB? If yes, how? Do I need to flash TWRP or something else on the Nabi before?
Thanks in advance for your help.

The latest TWRP should have a section under the wipe menu where you can repair the file system which is probably easiest, although you need to be careful what you are doing in there as it is called the "wipe" tab for a reason. Should be able to go to wipe menu, select data partition checkbox, select change or repair filesystem(don't swipe to wipe, click the words check/repair etc) and select check in the next screen.
To do a filesystem check the partition can not be mounted so you do it from recovery not in Android. Since stock recovery you can't use ADB you pretty much need TWRP one way or another.
If you don't want to use the graphical interface in TWRP you can do it over USB with ADB and use e2fsck on the partitions after unmounting them, but it's going to be doing the same thing you will just see a more verbose version if you do it over adb.
Thanks a lot, aicjofs.
I will try to root and install first TWRP, as my Nabi is still untouched.
One thing I remarked: at the moment, when I go in the (stock) recovery and want to do a "Wipe data/factory reset", 2 lines are displayed before "-- Wipping data...": "E: missing bitmap stage_empty (Code -l)" and "E:missing bitmap stage_fill (Code -l)". After that, the wiping process seems to run normal, as I get the message "Data wipe complete." at the end.
Do you know what that lines are meaning? Could those lines help to debug the main problem ?
Update: NO WAY to get TWRP on my Nabi, regardless how hard I try...
NabiLab 2015 recognize the Nabi without problems, but as soon as I select "Recovery installer", Nabi should reboot-bootloader (I suppose), but hangs at Nabi Logo (the small icon in the middel of screen) forever. Also in Control Panel, the device is shown as ""Fastboot" with the error symbol and the indication that the driver should be installed again (but of course, when I try to do it, Windows tells me that the newest drivers for that device are already installed).
I also tried with using directly adb in a cmd window, with the same result, as soon as I type "adb reboot-bootloader" and press enter.
I am really out of ideas...

The hang with Nabi logo is because the fastboot driver is somehow broke. You will likely have to install it manually. Which driver are you using?
I gave most of the driver options here http://forum.xda-developers.com/nabi-2/general/nabi-information-t3229119

You were right! I've installed the "nacked" driver on a fresh windows 7 and now I have TWRP on my Nabi 2!!! Thanks a lot!!!
Now is there a way to get rid of the freezing problem when I attach the charger while Nabi is on? Right now, if I attach the charger this way, Nabi 2 will freeze completely and only a reboot can get the normal functionality back!?!
Charging the Nabi in "off" state works however...

I dont have Nabi2's anymore but both my kids tablets did the same thing. I never really found a solution. I did buy a cable from Nabi store that has the orange braid covering. It seemed to make a difference, but it still happened from time to time.
Happy New Year!
As I mentioned, I was finally able to install TWRP and did all wiping, cleaning, repairing tasks that were available
After that I flashed the "Nabixus 0.1beta for Nabi 2" ROM which worked very nice.
But... I still have the same problems starting up the Nabi!
When I finally succeed to start it (after many trials), it works well, but if I let it go in standby and wait more that a few minutes, I am not able to wake it up again and I have to do a restart (about 10 sec. hold the Power button down).
What I`m not getting at all: is this a software or a hardware problem? Can my Nabi 2 be repaired after all, or I just have to scrap it?
The last thing I could still think to try would be to repair the partition table through TWRP / Adb / Adb shell. Should I try it? Where can I get a good partition table for my NV7A and, after having it, which commands are required?
... aicjofs, please... help

You can't repair the partition table from adb/TWRP. It's read only. You could through nvflash but I don't think the partition table could possibly cause the issue. I think you are meaning fix super blocks and inodes of the filesystem? Even that is a stretch if it's happening how you describe it but with a try. Did you try repair filesystem like we talked about earlier? If not backup all the data and try a wipe data. That will make sure to blow away and reformat the data partition.
It could be hardware. I know for sure the charging system causes it when plugged in but not about the first boot stuff or when it's not charging.
Thank you aicjofs for your answer,
yes, I did attempt to repair the system, data, cache and it was successfully. I did it several times. I also wiped everything a few times and installed the Nabixus ROM afterwards. Nothing helped. It's like the operating system needs to "get warm" somehow, because I have to try to power on the system many times, until I get it work... but after that, if the Nabi goes in standby, I have to start the whole thing over
How can I check for damaged blocks, etc.? If I can do it and find some, could they be marked as "bad" and isolated? Would it make sense?
