[Q] NT Internal Memory stuck on Read Only - Barnes & Noble Nook Tablet

Hi everyone,
I was on here a few months ago with issues regarding my rooted NT. I was told that after I ran Chainfire 3D, it somehow changed the internal memory to Read Only- no changes can be permanently made. Every time it is rebooted, it resets to how it was setup prior to running Chainfire 3D. I just wanted to know if anyone has resolved this issue yet, since I saw before that a few others had the same issue.
Any help appreciated!
Thanks,
Ashlee

My NT is in this state for 5 month already. This is not related to Chainfire 3D, I never used it. We need hardware guys here, Adam Outler perhaps.

My bad...someone on the forums told me that's what messed up my NT. Anyways, yes, I've had the problem for about the same time as you!
Hopefully someone can help us out

Can you try to be more clear about your problem guys? Can you flash new cwm/twrp? Do you have a adb shell access with root privileges?
Just some question that need answering so we can help you out.
Also only 8gb or 16gb too? Thanks.

We can't change ANYTHING on internal emmc. So no, we can't flash twrp/cwm. But we can run it from sdcard.
Do you have a adb shell access with root privileges?

Yes, I do. Both in CWM and Android.
Also only 8gb or 16gb too?

16G only, I think.

ok then, go get chris's jelly bean 5.1 or any rom that will give you Cyanoboot and fastboot mode.
Prepare sd card with that rom.
Download this recovery:
http://www.multiupload.nl/ZPSLTX4223
Access fastboot from booting from sd card and stop boot at cyanoboot pressing N.
Then flash that recovery image and tell me if it flashes ok or you have errors.
If flash ok proceed to wipe everything and flash cm10/whatever (tm) rom except stock.

Hmm strange indeed..
ok dont reboot and try this,
Flash recovery then
fastboot continue then volume rocket select recovery from menu and boot into it.
Tell me what you have, stock or new one.

Well,
I can only state here that i don't in anyway have any responsibility for anything that can happen to your Nook Tablet following my recomendations.
All am trying here is to help you and others with same problem to have a functional Nook Tablet with no one blame me for any bad side effects that maybe arise.
I type these words because next steps are going to fully wipe your Nook and you maybe as well need to recover it by your self if it works. You have to look into forum for solutions.
Ok now for the trial and error:
1St download the factory image from Barnes and Noble in zip state dont unzip it dont mess with it and place it where fastboot.exe or binary is.
Boot into fastboot and
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
Then:
fastboot flash recovery (stock barnes and noble recovery).img
fastboot -w update factory-image-1.4.x.zip
Fastboot reboot.

While you are in Recovery wipe everything.I hope this time we succeed!
And find a way to flash a cm10 rom like 0.5.1 etc
Like:
fastboot -w update cm10-rom.zip

I was trying to wipe everything multiple times before, with all methods on forum, and every time after reboot I was still having the same CM7 with all my data, as 5 month ago. I'm just want to determine, whether this is faulty chip or some kind of software lock.
Sorry, my English is horrible.

Maybe it has to do with the locked bootloader.
Something you did and doesn't play well with it.
Did you try dd the bootloader from a working one?

Yes, I did.

My personal opinion would be to return the unit back to B&N for an exchange.

How? I'm from Ukraine, not from US. Besides that, I have some personal data stored on internal memory, that I cannot erase.

The process here: http://raywaldo.com/2012/06/how-to-un-brick-a-nook-tablet-8gb-or-16gb/ should clear up the Nook and return it to real stock. Once that is done, I have guides for installing CM7, CM9, or CM10 on the same site.

I have tried this method before, with no results

guide: how to have unlocked fastboot without flashing

I recently discovered this, and I thought it would be of some benefit to those who are wanting to unlock, modify partitions, etc without the need to flash derpunlock.sbf or modify your photon in any way. What you need to do this:
1) fastboot for Windows or Linux
2) unlocked RDL3 (ramloader) which I am providing
The process is very simple, reboot your Motorola Photon, and hold the volume down button and power button. You will see "fastboot" on the screen, now press volume up. Connect your phone to your computer, and issue the following command which I discovered:
[email protected]:~$ fastboot flash rdl.bin RDL3_unlocked.smg
sending 'rdl.bin' (3072 KB)...
OKAY [ 0.193s]
writing 'rdl.bin'...
OKAY [ 0.000s]
finished. total time: 0.193s
This will load the unlocked ramloader (unlocked will be displayed at the top even if your phone is locked) which is normally only loaded into ram when flashing an SBF! Amazing, I know. Now you can do all kinds of stuff and you've made no modifications, just issue a "fastboot reboot" and nothing has been modified. Now you are able to erase boot, recovery, oem unlock, etc. Here is an example after you have executed the above. This is just me restoring my default boot and recovery partitions which you can't do from your locked bootloader:
[email protected]:~$ fastboot erase recovery

what would be the process coming from locked stock _6, would i just flash clock work mod, flash rom.zip then OP's inputs?

The process of loading the unlocked ramloader is the same regardless of your firmware, even if the bootloader is 'locked'. The ramloader is just that, its written to ram, and so when the phone is reset the code is cleared out of memory. This means to unlock your radio, you don't have to flash anything to your ram, flashing rdl.bin basically just loads the ramloader to executable memory, then jumps to it. I'm still working on figuring out how to use this to chain load a custom recovery.
Love this! Keep up the good work!
So can I flash CWM after this kind of unlock the bootloader and then custom rom.

Will this be useful for the ones that flash the electrify rom on the photon?

I like what I m reading. Sounds like this would be the saving grace for those photon users stuck on an electrify rom (and yeah I m one of them!). Please let us know when you get to rewrite system with a custom rom with this method!

Not yet, you can flash it but it is not yet bootable since I haven't figured out yet how to jump to recovery from the ramloader (you'll probably get an error 2 if you flash CWM then boot to recovery). After you reset your phone, rdl.bin gets cleared out so the same protection mechanisms are still in the bootloader. It's something I'm working on.

I already can. just do the following:
fastboot flash rdl.bin RDL3_unlocked.smg
fastboot erase system
fastboot flash system your_system_file.smg
fastboot erase boot
fastboot flash boot your_boot.smg
fastboot reboot
EDIT: file extension doesn't really matter, can be smg or img
Theres also updating from fastboot using a zip file, I'm not 100% sure if this works the same as in recovery:
update <filename> reflash device from update.zip

I'm pretty sure the reason you're receiving this error is because this RDL is from derpunlock.sbf from photon_pudding.rar. I'll post the unlocked pudding electrify ramloader.
Attached is the unlocked pudding electrify ramloader, run:
fastboot flash rdl.bin RDL3_unlocked_electrify.smg

[Q] Tab Bricked...

Hi.
After I've tried to install a custom rom, I've done a very big mistake. Now I can't boot the tab, and if I try to go in recovery or wipe data through fastboot i get the fatally error "unrecoverable bootloader error 0x00000000". I haven't any nvflash backup and have the JB bootloader (10.6.1.8). The only thing that works are the APX mode and the fastboot. I'm feeling a very idiot because i bought it yesterday.
Now, what can I do? Dump it and f**k myself? :crying:
Sorry for my bad english, thank you for your help.
I realized I'm screwed. But I've tried something...
When I go run the fastboot mode and delete a partition, for example:
Code:
fastboot erase recovery
works, and after I can run other command. But if I use:
Code:
fastboot flash recovery recovery.img
seems it works, in fact the output is

Hello. Today i tried to flash the phone to the stock ROM twice but it didnt work probably cause unlocked bootloader and custom recovery (TWRP).
So i brick the phone and now i cant access the rom or the recovery. All i can do is access the fastboot mode. I tried to install the new recovery through fastboot but it doesnt work.
I tried the twrp 3.0.2.0 and 3.0.1.0 for yuga.

Could somehow stock rom affect the bootloader when i was flashing through flashtool ? I tried to only boot the recovery from the img, the command worked but the recovery did not boot.
