NVFLASH BootLoop Scare - G Tablet General

So i've flashed plenty of roms on my android phone with utilities like nvflash so it seemed so simple. I guess i repartitioned some odd way and got my self stuck in a bootloop of the birds and g tablet logo. Well after scaring myself really bad thinking I bricked my tab I saw something showing that you can use CWM and just repartition the 20480 or something / 0 then rebooted and everything booted up normally.
So those who think your stuck, just put the CWM external files on your sd card and re-partition. Woohoo i'm back in business.

Stuck in the same boot.....
I did copy the cwmod_microsd in the card and re-start in recovery but it doesn't find the recovery package and just continue going to the same thing (it get stuck in the gTablet logo), don't know what else to do... can somebody please give a little help?
Thank you...

EVO wont Boot!

Hey guys. So I was flashing Cyanogenmod nightly version #256, and I was getting really frustrated with the random reboots, so looking around online someone posted a solution, and I attempted to install the incredikernal. afterwards my phone got stuck on the white screen, so I formatted my sd card like an idiot and I litteraly have no image to boot my phone in, what do I do??
well...You can try downloading a new rom from your pc and insert the sdcard into an adapter.Then flash it

Custom boot animation bricked my tablet?

Aight, so here's what happened, installed a custom boot animation, but it's in a loop, it keeps playing, cold boot doesn't work, recovery gives me the dead android, can't rly acces my tab in any way. The only thing I can do right now is getting it recognized as fastboot, everything else I tried results in my Hardware manager not even recognizing my tablet.
I got a rooted JB, not unlocked.
Rly got no idea what to do now, is it perma bricked or can I find a way out again?
Update: just left it bootlooping while I went for a spliff and voila, seems like it's done a factory reset or so
Looks like i lost EVERYTHING on the tablet but seems like it's working again, probably lost root etc though :/
Update 2: google is reinstalling all my apps now, gonna take a while
Update 3: at first looks, I still got root, rootchecker says I still have root, don't know what should happen with like ES file explorer if I don't have root but so far it all seems to work. Got it figured out what happened too, it wasn't a boot loop, it was just the custom animation that sorta ****ed up and kept rolling, I then started a recovery but didn't let it finish, so when I finally decided to stop tampering and just let the battery die out, it had enough time to actually finish that recovery.
Update 4: first reboot got me again, still the same animation, well, let's hope I still got root after next recovery, so I can fix that.
Update 5: all is good again, besides that everything from tab is gone, aah well, kinda wanted a fresh start with jb anyway

Please help me!

Hey guys! im falling apart.
Installed wrong CWM and the tablet just wont load up, stuck on boot logo, I have no access to internal memory,
I have just recovery.img on the internal sd card, i think that is what causing him not to load, the recovery is screwed up!
If anyone would help me i will really thank him :'(
Reflashing is your only option. I can't be more specific because you didn't say which tablet you have.
SOLVED

[Q] Boot issues after installing CWM recovery

Hey there XDA! I thought I'd root my P920 a few days back, which went smooth, no issues and I was enjoying my newly rooted Optimus
I wanted to get a new kernel for it, so first thing I did was install CWM, Then clicking on 'Flash ClockworkMod recovery' in the app, which then flashed a CWM recovery if I'm not wrong. The final thing left to do was rebooting into the recovery, which I did by clicking 'Reboot into recovery'
Now waiting for the phone to reboot into recovery, the LG logo came up on screen, and stayed there for some time, which is normal behaviour as it takes a bit of a while to boot up for me, but then something odd happened, the logo disappeared and the screen blacked out, leaving the phone off. Immediately noticing this, I tried to boot the phone up as I normally would, but again the same thing occurred, logo appears, then phone blacks out and returns to an off state.I repeated this a few times, but to no avail.
These are some things I tried:
Normal booting multiple times
Normal booting after battery pull
Normal booting while charging
Normal booting after removing SD card (this resulted in a blue screen appearing after the LG logo on bootup, though I was impatient and didn't wait to see what would happen so I pulled the battery out )
Normal booting after removing SD card and then battery pull
Normal booting after removing SD and SIM card
Normal booting after removing SD and SIM and then battery pull
Booting into recovery multiple times
Booting into recovery while charging
Booting into recovery while charging
Booting into recovery after removing SD card and battery pull
Booting into recovery after removing SD card
Booting into recovery after removing SD and SIM card
Booting into recovery after removing SD and SIM card and battery pull
So as can be seen I've tried tons of situations
A few times, the screen turned into repeated patterns of static colour, it's difficult to describe but its only happened a couple times, and appeared on top of the LG logo. From what I've gathered, something is preventing the phone from booting up properly, either normally or into recovery, unless the problem is something else entirely. Also I don't have any NANdroid or Titanium backups.
So my questions are, could it be that I need a full charge for it to boot properly? Otherwise what's the problem and how do I get the phone to boot normally? I would prefer that all data on the phone is not erased but if it's a must then so be it.
I really appreciate any and all help I can get here, thanks!
P.S. I'm new to rooting and customising at that level, so please ask for any additional details or anything I was unclear about. Apologies to all for the lengthy first post, thanks again!
AW: [Q] Boot issues after installing CWM recovery
Hi welcome
Girst thing you have to do before flashing or doining something with your phone is a nandroid backup. I do always a titaniumbackup and saved pictures and music manually only for insurence. Next thing, whcich app do you use for flashing cwm?
For your data im not sure if you can rescue that i dont think so.
If i understand it right your are stuck on bootlogo right?
To rescue your phone you can always go back to gb by flashing kdz file with flashtool. Watch here
http://forum.xda-developers.com/showthread.php?t=1540163
But in that case you will loose all your data on phone.
P.S. and next time if you want to flash cwm use os_hackings all in one tool. And flash twrp recovery its better and didnt have so much bugs
Sent from my LG-SU760 using xda app-developers app
I used ROM Manager for flashing cwm, yes I am stuck on bootlogo
Thanks for the help! I'll try out what you suggested and report back here if it works

i bricked my sm-g935f

hey guys, i think i really did everything wrong about rooting...
i tried to root my s7 edge with odin, so i flashed the newest twrp and that worked but my phone wasntn rootet, so i flashed magisk v16 from twrp after and got stucked in the samsung logo and my idea was to flash lineage 17.1 and superSu and now my internal storage is no more shown in twrp and my phone now is not even stucking in the samsung logo anymore, it stucks in the really first "samsung Galaxy edge screen" and even twrp stucks in booting screen, only thing working right now is download mode
i did everything youtubers told me and i still stuck in this screen and wanna know if theres a solution, or is there no chance left for my phone?
ofc i havent done any backups..
so at first, pls dont judge me, im really new to the scene and on youtube everything looked so easy and the second thing is my language
my english is not that good
is there a way to completely go back to stock and stock kernel or might the internal storage got damage by all the things ive done?
couldnt find any solution on xda or youtube
Try to boot into twrp again.
Flash encryption file (no verify opt encrypt 6.0.zip) for internal memory. Think this is your problem. Your memory is encrypted.

You can try this link to unbrick your phone and try to root again.

Hey,
I actually had kind of same problem when I tried to flash stock ROM,
I got pretty much everything wrong when I was trying to make it boot again,
so I almost bricked it.
Only download mode was working and TWRP couldn't boot,
So I left it until battery drained and phone turned off,
after that I plugged the phone into a PC, opened download mode and flashed only BL, CP and CSC in odin, one by one.
I skipped AP because it got stuck every time I tried to flash stock ROM,
But flashing TWRP was always successful.
So I flashed TWRP, successfully, and tried to boot,
and it booted, it took several restarts but it actually booted.
If you boot into TWRP you will be able to get it to work again,
by repairing or formatting partitions and flashing stock ROM after that.
