Greetings,
I have two Vibrants - one I bought from TMobile (and running stock everything), and one I later bought on eBay (running Froyo thanks to TeamWhiskey). I bought the second phone so that I could mess around with flashing ROMs and be able to brick a phone without it mattering. Hah.
Last night, for no reason I can discern, my stock TMobile Vibrant phone spontaneously soft bricked itself. My eBay test phone is fine.
I don't hugely care WHY the Tmobile phone bricked itself, but what I do care about are the pictures that are on the internal storage area.
I used Odin last night to flash in T959UVJI6.tar (but I did NOT use the 512.pit file). One of the posts I read said that doing so should fix a soft brick, without messing up the internal user storage area where pictures are located. No change - when I power on the Tmobile phone it hangs at the Galaxy S logo and then goes black.
Does anyone have any suggestions of how to access the internal storage area of a soft bricked Vibrant? And/or, can someone explain or point me at an explanation of what impact using a PIT file (vs not) and checking the "reformat" box in Odin (vs not) will have on the internal storage area? I don't care about overwriting the apps - I am just hoping there is some way to pull off the pictures or unbrick the phone WITHOUT deleting them.
Many thanks!
Wrong section..probably going to get flamed. Odin again with the pit file and you still wont lose pics and stuff. But next time...Q and A section...not being a ****, but that's where you ask all your questions.

Thanks for the reply. Is there some way I can move my post to the Q&A section? Or is that something only a Mod can do?
Also, do I check the reformat box or leave it unchecked?
Thanks again.

No need to reformat.
That's only for special occasions, really. And yeah, as far as I've seen, only mods can move posts.
yeah i would also like to know to that. the other day i deleted the 3d gallery app apk odex files because it was annoying the hell out of me with it's referenced folders - i tried clearing the default folder and but it was still showing random pictures from the shutdown folder and where ever else - so what did i do? i backed up the apk and odex file then deleted them from the system folder. rebooted w/o any issues - then i tried installing the apk... nothing - kept giving me a failed app install notification. i tried this 3-4 times then gave up. at this point i restored the apk/odex file to the system folder and rebooted the phone - nothing... gets past the galaxy s animation screen then screen goes black... nothing....
tried multiple reboot and keeps getting to the same black screen of doom - the other odd thing is windows do recognize it after it gets past the galaxy s boot screen and into the blank screen when i check in the device manager
ADB pull /sdcard/"whatever u have on ur phone"
Learn ADB
Reading is Fundemental
I'd also like to know if there are anyways to access the internal memory of a soft bricked phone. I know I can use ODIN, but I could fix the problem right now sans computer or USB if Clockwork recovery could access my sd card; I flashed a new kernal on stock JI6 and apparently needed to to flash a backsupport.zip first.
So, I don't have a cable with me, so can't use ODIN, clockwork recovery doesn't restore kernals and doesn't access the SD so... I'm screwed until I get home (not a huge deal). Alternatively, I could also not get clockwork to USB mount so I don't think that works either.

lol thanks man. but i also tried that. adb can't recognize it - and i found out it's the hard lock t-mobile version where doing the three button power up does not get you into the recover screen. unless i read that wrong? lol
Update: I used Odin again, this time with both the TAR and the PIT file. Same result as last time. Odin appears to have completed copying everything over successfully, but upon reboot, I still get the soft-brick Galaxy S that doesn't go away.
I didn't try ADB earlier because all the posts/various docs I read thus far seemed to imply that ADB needed a normally functioning phone - not one that got stuck at the Galaxy S logo. I was wrong.
Here's what I did, hope it helps someone else. [Commands below assume you're using windows, and want to copy the entire contents of the internal SD memory (called "/sdcard") on your PC that you created (e.g., "c:\sdcard"]
1. Install ADB
2. Plug in soft-bricked phone and power on
3. Run command prompt and navigate to the directory where adb.exe is located. In my case, it was C:\Program Files (x86)\Android\android-sdk-windows\platform-tools.
4. From the command prompt:
adb pull /sdcard c:/sdcard
NOTE: the c:/ slash should be as shown - not c:\ as you would normally type under Windows.
392 seconds later, I had all 8G of photos on my PC.
I still don't know why the stupid phone won't boot properly, but now I don't care and can blast everything away. Thanks to everyone who contributed. Next time I'll be sure to post in Q&A instead.

Please put your questions to: Vibrant Q&A
I've seen a number of requests for this functionality and recently it became necessary for one user who had a disabled Home Key to clear cache and data without the use of ClockworkMod. I have reserached two methods to address this issue. These instructions require some familiarity of android, computer and tablet terminology and usage. Feel free to ask for clarifications in comments. Here we go...
Method I - Stock Recovery Command File
Technical: Stock Recovery command file can be used to perform a few additional functions as well as to alter the path to update files. These commands will execute with all privileges available to recovery mode.
Advantages: Very easy to use. Very little technical knowledge required. No third party software is required for use.
Prerequisites: You will need a MicroSD card formatted FAT32 and a method for transferring files from your computer to the MicroSD.
Usage:
1) Prepare a text file named "command" (no file extension) with one of the following commands on a single line. The wipe data command will wipe both data and cache. Wipe cache will wipe cache only.
--wipe_data
--wipe_cache
2) Place the file in a folder named "recovery" in the root directory of your MicroSD card.
3) From a powered down state, insert the MicroSD card into your tablet and boot into recovery by powering it on while holding down the Volume Up key.
4) Allow the command to execute completely then the tablet should reboot (this may not occur automatically depending on firmware installed).
Method II - Updater Script
Technical: The attached "Updater Scripts" perform delete commands (recursively if necessary) on the named directory or file(s). The directories are mounted automatically by the system before the script executes but it could be easily revised to include that step if necessary. The partitioning, formatting and directory structure are left untouched. Only files are deleted.
Advantages: No third party software is necessary for execution. Relatively easy to modify for more surgical precision (i.e. leaving installed apps but clearing possibly corrupted system data). Included example: "Clear Battery Stats"
Prerequisites: You will need a MicroSD card formatted FAT32 and a method for transferring files from your computer to the MicroSD.
Usage:
1) Download the attached archive (ClearData.zip) to your computer.
2) Extract the files to your computer. You should then have a folder named "recovery" (which contains a file named "command") and an additional archive named "update.zip"
3) Place the recovery folder and the update.zip in the root directory of the MicroSD card.
4) From a powered down state, insert the MicroSD card into your tablet and boot into recovery by powering it on while holding down the Volume Up key.
5) Allow the script to execute completely then reboot the tablet (this may occur automatically depending on firmware installed).
This will become handy someday.
Thanks for sharing your knowledge.
You're welcome. One quick note... the new stock recovery adds a menu simiilar to ClockworkMod. These methods will still work since the recovery folder/command file are checked first but it really isn't as necessary any more.
Need Help
Tried both methods above but either way I get to the viewsonic splash with the message "Booting recovery kernel image" in the upper left and it just stays there, stuck there, I left it for a long time to see and it never leaves that screen.
Any ideas?
Me too
I can't get into clockworkmod either. My machine is running faster. I almost hate to mess it more.

That's an indication that you may have more serious problems. nvflash will be required. http://forum.xda-developers.com/showthread.php?t=861950
Once done you will likely need to install ClockworkMod and repartition your internal storage.

If your tablet boots properly but you can't get into CWM then it probably isn't installed properly (or at all). http://forum.xda-developers.com/showthread.php?t=865245
Keep in mind that CWM is NOT compatible with all ROMs. Make sure the developer for your chosen ROM recommends it before installing it.
Does your method in opening post have to be run from external micro sdcard?
Both methods are performed with an external MicroSD card. They will work from internal also but it is a little more difficult to get the files in place if your tablet is not booting properly.

so your method is a simple way to replace one of the main uses of Clockword MOD?--Plus you stay stock more or less.
That is correct. Method II can also be modified to be less intrusive (leave user apps installed) or embedded into update scripts to perform a wipe during new ROM installs.

Wipe data does what--remove the apps installed?
And the partitions?
Your post is very interesting. It implies that you have a knowledge of the g-tabs partition structure. I have played with Linux off and on for the last 10+ years. When I began, I used Slackware and when you set it up you had to manually create partition tables using fdisk. You were only required to create two - the data partition and a swap partition but it was often recommended that you create several others - one to contain the home directory to prevent users from using all the disk space (in the days of small disks) for example. It appears that there are a lot of partition on the g-tab. Up to now, I have used various wiping tools like clockwork or calkulins wipe all on faith. I would really like to know what all the partitions are and what is in them. I have used terminal to get to the root folder and tried to do an fdisk to display the partitions but try as I might everything remains hidden. It would seem that a script like yours could be adapted to do many things but I would certainly want to understand the structure a little better before I did anything. I have searched and been unable to find that information. Can you point a way for the curious to learn more about the partition structure on the g-tab?
Wish I had a direction I could point you in. What I've found so far has mostly been stumbled upon while looking for something else. What I can tell you is this...
1) When using fdisk in Android you must specify the device to look at. Try something like: fdisk /dev/block/mccblk3 That should list the current partitions as defined by CWM or whatever was used originally.
2) Within one of those partitions in the list generated above are sub-partitions holding the bootloader, system, data, etc partitions. You can see how they're described in the .cfg files in the nvflash restores that are lying about.

Removes user apps and their associated data as well as system related data and settings.
K J Rad - any idea if the partition size can be set with these methods (2048 & 0) in case I can't get clockwork installed?

I'm looking for a solution to that problem. Unfortunately these methods still require the ability to get into recovery mode which likely won't work if you're having trouble getting CWM installed.
If, however, you can get into recovery... then it is theoretically possible to create a script that would accomplish that. As soon as I have one I'll be adding it to the mix ;-)
Edit: I've found something I think will work. Will do some testing tonight. It will still require access to recovery.
I wasn't sure if you saw my other post but I am seeing no partition 0 when I NVFlash with a verifypartition.
http://forum.xda-developers.com/showpost.php?p=13059520&postcount=57
I haven't yet but I will. Let's try to keep this thread on topic. Thanks.
More thoughts:
because I went w/ cyan7 is it possible i have a "bad" kernel and that the stock bekit-1105 or the roebeet-3588 files are crashing w/ the kernel in place already?
I know custom ROMs can have a custom kernel applied separately, but I have no idea whether cyan7 loads it's own kernel...
I have yet to try the nvflash_gtablet_46 version, as I see the img files w/in are different from the original 1105 .zip
Also:
read on another thread that part 2 and part 3 aren't loading for other users when doing nvflash - I did notice that it pauses, runs some stuff, then starts loading part 4 through to the last part, then success. - do part 2 and 3 run for you?
edit: I see a 4349 downgrade.zip in another thread for those who got the OTA update but want to go back to stock 3588 prior to jumping off somewhere else - I can't expect that would help me as I can't do squat w/ recovery yet, but could that possibly "reset" any bad kernel problems? - again, I'm just thinking out loud.
This is well outside the scope of this thread but I find some of what you mention interesting so I'll address it and then end any further off topic discussions.
I did not build nor have I ever used Cyan7 so I have no basis for an opinion on the matter other than this... Each ROM comes with a kernel installed so if properly done an nvflash should overwrite any "bad" kernel.
Part2 and Part3 do indeed load, they are just displayed differently than the other Parts. Just minutes ago I flashed down from Mountain Laurel (4349 based with the new bootloader and recovery) with absolutely no trouble. I can, and have, read back those partitions after an nvflash to prove that point.
The 4349 downgrade will only work for you if recovery is working. Having never used it I don't know that it would "reset" the kernel but any subsequent flashing of a new ROM image would.
I am working on a stock recovery solution for partitioning but it isn't likely to help anyone who is stuck in an APX loop. I do have some ideas on what might help for that condition but I haven't been able to get my hands on one for testing and trying to help people here is like being a consulting mechanic for a car repair that's in someone else's shop having work done on it that you're not being told about.
I'll be happy to address any further comments or questions regarding your specific issue in an appropriate thread or via PM. Thanks.
alright i have this problem and i am quite panicking now.
i will set everything straight , i hope someone reading the forums can help me asap !
- have a sgs2 unbranded (hk)
- has ICS 4.0.3 stock rom, rooted.
- i don't remember if usb debug mode was enabled
- i messed up in some way with the file /system/build.prop but there is a backup in /system/ called build.prop.bak
- phone doesn't boot anymore as it's stuck at the logo
- recovery and download modes work however
#need a way to delete the build.prop and replace the bloody file with the one backupped. I would like to avoid having to format the phone as i do not remember when was my last kies backup...
what i tried:
-adb shell: it doesn't work. for some stupid reasons the drivers won't be recognized (i have download android sdk and usb drivers), but when i plug the phone in recovery windows just says Device Unknown and even if i update drivers manually it would say that current ones are functioning so no need to update.
if i connect the phone to usb while it's stuck at boot logo, it would recognize the device through samsung drivers (except MTP of course, that would give error).
in both cases adb shell doesn't list any connected device: even if i kill-server and start-server it still doesn't list anything.
-tried using droid explorer in both frozenboot mode and recovery mode, doesn't see anything.
-tried using that other program called SuperOneClick or something like that, that has a "check drivers" button in advanced: if the phone is in recovery pressing the button doesn't do anyhing; if the phone is in frozenboot it asks to download and install some drivers but when i press yes a message appears with " no more data is available " !
i tried this procedure on both win7x64 and winXPx86: same results. reading around , someone says that adb shell will never work if usb debug is de-actived, like i said i cannot remember if that's the case.
-zip package: i created a package to try and overwrite the file with a custom working one i got. i put the package in the root of the micro sd , put the sd in the phone and booted in recovery.
but when i am in recovery the bloody CWM 5.0.2.7 says error to mount /sdcard, or E: could not mount /sdcard , same if i try to mount/unmount /sdcard. if i go to mount external usb card or whatever it says that a file or a lib (cant remember the exact message) was not found.
i have no more ideas of how to solve this, please be patient :<
edit: is there a way to soft format the system folder so that i don't have to properly wipe all my user data and it only affects the system without other contents?
If adb doesn't work hen you are in trouble, better download some non wipe rom and flash it over the existing rom so that your user data will still be there.

can you expand on this?
give any suggestion/example?
isn't there a soft temp rom for emergencies like this that you can just start, make modifies to fix and reboot (similar to the process to boot ubuntu on windows, fix issues and then restart normal windows? )
i would so like to make adb work.. but how.!!!
probebly will not work but try backing up of your ROM from CWM working or not..then just back up current one...
you can restore apps & data lateron from nandroid backup with some application like titanium backup donated version.
i made a backup . but since the external sd card isn't found by the recovery, now the backup is sitting on the internal memory.
the problem is that, if i flash something with odin now, won't odin wipe everything in the internal memory killing my backup as well?

nope....it will be there dont worry,
just check one more option, go to storage and mount, there is one option mount usb storage, after connecting your phone to PC just mout that and check, are you able to access the SDcard from the computor ot not, if yes, just copy paste your backup to the computor.
then flash a firmware from ODIN
Did the very same thing myself yesterday.. Most ICS-roms from Samsung is non-wipe, so you can just flash it over again with Odin.. Then you just need to root and make customizations (if any) again

could you be more specific on the process ? can you suggest me one to flash with odin ? i need to enter the OS , transfer my backup on my hard disk and then restore the whole thing.
currently my kernel is CF-Root-SGS2_XX_XEO_LPQ-PROPER-v5.4-CWM5.tar

you try to reflash once more CF-Root (.TAR)only from odin
then check "E: cant mout...error" is rectified or not.... also check booting or not,
still no hope...you flash the same firmware again and Cf-root, your SD card data will be there for sure as far as our expereicne till now..
first part of your comment: i tried reflashing the kernel; no changes. same errors
second part: shall i try using the same firmware from my previous post then?? not other roms? after that i will put the root and check if internal memory is still there. if it is i will copy it on my hd and restore.
if it is not there anymore..............
so the end of the story.
thanks to anyone who helped.
the resolution was much easier than everything else.
opened odin, pda loaded my same firmware which was the HK stock update to ICS and reflashed.
what it did was apparently and overhaul of the system folder, that's it.
any data was still there, as well as the backup that i did and all my apps etc etc etc.
however especially at first it looked a bit unstable, with processes failing randomly. now it seems it has stabilized a bit, but still when i try to run a Kies backup, the phone kies process dies and the backup gets stopped.
i still don't know how to fix this, but i'll be looking into it.
so, the morale out of this was at least for me: if there is some **** up within the system folder just reflash the same rom installed. i feel so stupid now for having made such a fuss when the solution was so easy and straightforward
NICE that you finaly came across and able to boot , now you make the Titanium back of your all apps and data transfer to PC....forget the system data.
and move to a nice stable ROM
"Unfortunately, wssyncmlnps has stopped"
anybody knows about this?
Hi all.
I've just installed some app that broke down my S3 stock OS.
The OS was rooted, and I gave the crappy app superuser access...
It was supposed to change the DPI setting, but now it's boot-looping over the Samsung logo.
Now I'd like to recover my data, photos and stuff...
CWM Recovery 5.5.0.4 is installed.
I can start a backup, but it won't complete since I don't have a large enough SD card at hand (it's a 32 GB SGS3 with a bunch of large videos...).
I don't care about the movies, just the photos, but there's no option for a selective backup...
I also tried updating CWM to a more recent release with Odin (downloaded .img and tar'ed it...), but it won't go further than SetupConnection.
I've not tried a factory reset of anything else yet...
Is there a way I can still recover my data, or should I just get over it and try to flash the whole thing back with Odin?
Thanks for your help.
Adb backup?
maybe reinstalling the ROM can fix it ?
The other thing you can try is adb pull /build prop, edit LCD density back to 320 and adb push it back
Thanks for your answers.
adb looks like the way to go, but I never managed to get it working on my computers.
"adb devices" won't list any, "adb shell" returns "error: device not found".
USB debugging was enabled in the OS.
Is the phone supposed to be in recovery mode or download mode? None works... (Also tried with the OS running before it started crashing)
Is there a setup guide somewhere?
Actually, working with Android on Windows (XP x64) has been a total nightmare so far.
On my main computer, Device Manager loops forever on device detection / driver installation, and successive driver installation/uninstallation/reinstallation mangled WMP10 completely (and since it's tied to Windows, I can't reinstall it).
On other computers, driver installation went fine, I hardly managed to copy movies to the phone through MTP / WMP, and never managed to copy anything back.
I only ever managed to move files over wifi, but that's at wifi speed, not USB2 speed...
And now that I gave Kies a try (stayed away from it so far), it keeps eating 100% CPU whenever I run it.
I had that adb problem then I installed android command centre, and bam, it worked! Will try and find link for you....brb
Finally managed to run adb on the computer with Kies installed.
I'll look into this.
Here go
http://forum.xda-developers.com/showthread.php?p=36671130
Can't use adb pull/push anymore: in a previous attempt to reduce the nandroid backup size, I formated the system and cache partitions.
Then I managed to run a full backup with CWM Recovery, but can't find my files in there.
The backup files only contains application data, but the sdcard folder is totally missing.
Well, it appears the problem indeed was in build.prop.
My backup has 2 files: build.prop.bak and buid.prop.temp.
.bak has the old density, .temp has the new value.
Somehow the app failed to rename build.prop.temp to build.prop, and made the system unbootable.
adb backup won't work either: it's waiting for a confirmation on the phone, and doesn't seem to work in recovery mode.
Now browsing /data/media with adb shell !
I had to mount /data manually (in recovery), I guess the same is true for a recovery backup, and that's why I couldn't find my files.
Think I'll manage to get it all back now.
Thanks a lot slaphead20.

State of Nabi 2 Root as of 12/14?
So I have admittedly been out of the loop on the state of rooting my two Nabi 2s since after I restored them to stock and all back last year when they released the update that included the Gapps. So I've been running stock since then and am on the latest firmware (2.4.6 I believe). All is mostly fine, but I would really like to get the external SD cards to be writable again, and from what I can tell, I need root again to do that.
So...as of today...what is the state (and best procedure) of rooting the Nabi 2 on the latest OTA update? Is Nabi Lab still the best tool? From what I've pieced together from scattered threads, it's looking like possibly use Nabi Lab to install TWRP, and then use that to install the SuperSU (http://forum.xda-developers.com/showthread.php?t=1538053). However, I could likely be wrong...hence why I'm asking.

Nabilab will still work as long as you use a version with a Jellybean TWRP(since you are on 2.4.6).

I've searched high and low and can't find anything. I have nabi2S running KitKat. Every rooting guide I've found is for JB. Is there any way to root the 2S?

Stock Restore
Hi
I have downloaded NabiLab, as I am having wifi issues on my updated Nabi2. I unzipped, ran the .bat and chose option 3 (with my nab connected via USB). Nothing happened, no errors etc, the screen flashed up and shut down. Do I need to do something with the Nabi (recovery mode etc), do I need to install anything from NabiLab before trying this? Any help would be appreciated

What version of software? Use Nabilab2015 http://forum.xda-developers.com/showpost.php?p=59073456&postcount=2544
It has more diagnostic info. Just be in Android or TWRP with ADb enabled. It also can see if drivers are loaded.
Hacking Nabi2 to Allow Data2SD
I managed today to hack my kids Nabi2 to enable Data2SD. I was to frustrated by the limited space in the tab. My kids were complaining about not being able to add more games. Thus, I decided to take the risk of modifying the mount points of the tab to allow the data partition to point to a partition in a large sdcard, instead of the limited 4.5 GB space in the internal storage.
Warning: I am not responsible of any damage as a result of following the next steps. Always make backups
Note: I have the last update (KitKat) installed in the Nabi2
1- Dump the boot image from an adb shell:
Code:
su
cat /dev/block/platform/sdhci-tegra.3/by-name/LNX > /sdcard/boot.img
2- Open this url http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images
to see the instructions of how to unpack and repack the boot image. Note that, the splitimage script mentioned in the page can be found at https://gist.github.com/jberkel/1087743
Warning: do not do anything in the tutorial, just wait
3- Format an sdcard as one partition of ext4 type
4- Insert the sdcard in the nabi2
5- Use the tutorial in step 2 to extract the ramdisk contents from the boot image and then Modify the file "fstab.mt799" in the ramdisk folder by replacing the line
Code:
/dev/block/platform/sdhci-tegra.3/by-name/UDA /data ext4 noatime,nosuid,nodev,journal_async_commit,data=writeback,nodelalloc,errors=panic wait,check,encryptable=/dev/block/platform/sdhci-tegra.3/by-name/MDA
with
Code:
/dev/block/platform/sdhci-tegra.0/by-num/p1 /data ext4 noatime,nosuid,nodev,journal_async_commit,data=writeback,nodelalloc,errors=panic wait,check,encryptable=/dev/block/platform/sdhci-tegra.3/by-name/MDA
which switches the data partition mount point to be on the sdcard
and the line
Code:
/devices/platform/sdhci-tegra.0/mmc_host/mmc2 auto vfat defaults voldmanaged=sdcard1:auto
with
Code:
/devices/platform/sdhci-tegra.3/mmc_host/mmc0 auto vfat defaults voldmanaged=sdcard1:12
which mount your old data partition into the directory of the external sdcard
6- Repack the boot image as mentioned in the url in step 2
7- Copy the new boot image to the nabi2 sdcard
8- Once you copied the new boot image (e.g. new_boot.img), replace the current boot image with the new one using adb shell:
Code:
su
cat /sdcard/new_boot.img > /dev/block/platform/sdhci-tegra.3/by-name/LNX
9- Now the kernel is replaced and once you rebooted your external sdcard would be in use, but note that your device is now having an empty data partition on the external sdcard, so you have to setup everything from the beginning. Note also that your previous data partition is now mounted as an sdcard, however, you have to format it from ext4 to fat32 to work as an sdcard (you can do the format from setings->storage->sdcard format)

If you are not sure which line to change, I have the fstab.mt799 file attached with this post. You can simply replace your file with this one.

If you don't have the time to do all these steps, I have the modified boot file attached here.
Yo can either follow steps 7 and 8 above to write it, or use the fastboot command as follows:
Code:
fastboot flash boot new_boot.img
Nabi2 not found
Hi, I purchased a reconditioned Nabi, which was reset back to stock. The wifi worked fine, until I updated it through the tablet. I am now on version 2.0 with no wifi. I have tried various options through NabiLab , however my Nabi is not recognised as being connected (although windows picks it up). Please help!
Swipe to restore
I am trying to return my nabi to stock, i can get to the screen that asks you to 'swipe to restore' but the screen is not responding. I dont have issues with the touchscreen normally

That's weird...if you keep messing with it you may find a spot a little left, right, higher, or lower where you can grab the button to swipe....or you try to re-flash TWRP or maybe there's a new version of TWRP for your particular nabi software version.
did you ever get nabilab to see it? did you check the device manager to see if it was totally recognized? Are developer options enabled?

The Nabi is showing as a device, it's responds as it should up to the point of TWRP. I had to repeatedly press buttons to get to the restore swipe and have tried many times, unsuccessfully. Where do I enable developer options?
I am on version 2 (Nabi) and using the most up-to-date version of NabiLab. I am trying to restore to stock so that the software version goes back, as the update has stopped my wifi working. Even a factory reset doesn't take the Nabi software back further than v2.0

For developer options you go to settings, scroll all the way down, if you don't see "Developer options" there, press About tablet, then repeatedly tap build number until it pops up and says "You are now a developer!", then go back and now you should see the Developer options menu item, press it and then make sure it's on at the top and that the USB Debugging option is checked.....then try nabilab again.

Yes this is enabled, as without it I am unable to run nabilab etc. The problem is TWRP & the version of software I am running on the tablet?

Well, the touch issues are probably due to a bad build of TWRP but not necessarily the wrong one. The problem with nabilab not being able to see the tablet I think has to be drivers. Have you checked device manager to make sure there are no unrecognized things? 'cause the tablet show up as two separate things in there and it sounds like the USB storage part is working but not the adb and/or fastboot part(s).

I've managed to sort the drivers by installing PDANet, then managed to sort TWRP by installing an older version. I've now updated to 2.1 on the Nabi but no luck with the wifi issue..i'm guessing it's really broken and it happening whilst updating may have been a coincidence?!

It might just be broken but that's a heck of a coincidence... Do you have a backup from before the wifi issue started? If so, I'd try to thoroughly wipe everything but your external sd card and then restoring your backup and see if that helps.

Hi, I bought it as a reconditioned did unit. Turned it on, updates it (wifi worked) and then had this problem, so no backup to go back to unfortunately
