I have been searching all morning for the answer to my issue, but evidently I am not using the correct words in my search. Either that or I am the first person to need to do this:
In an effort to try to get Netflix working on my Gtab running Vegan 5.1.1, I have been trying differing edits of the build.prop file. Since Netflix is working on my original version Droid, I have been using it as a model. All to no avail. So, last evening, fully aware that I might brick the gtab and willing to pay the price of a reflash if necessary, I copied the entire build.prop file from my Droid to my gtab and rebooted. Sure enough, won't boot.
I have backups of the original working build.prop but cannot access it by connecting my gtab to my pc through usb. I can access the files on the sdcard but cannot figure out how to get into the system folder so that I can replace the offending file with a good one. I thought that nvflash might be my friend, but after reading everything I can find on that tool it seems that it will just reflash to stock.
I can reflash my Vegan install, and may have to do so....but is it possible to just access the files in the system folder? If so, all I would have to do is to delete the current build.prop file and rename my backup file back to build.prop.
Anyone know how I can do this?
Joe
You can us ADB to push (or pull) files as well as accessing the command line on your gTab. ADB is a development tool, and is part of the Android development kit. You need to install the driver that comes with it, but first you need to edit the .INF file with a couple lines referencing the gTab. You can find additional information about ADB in other posts.
If recovery is working ok then you could reflash your ROM or craft a custom update to replace build.prop.
You could also nvflash just the system partition if you have an image for your ROM.
Lots of options.
Edit: Just looked at the Vegan 5.1.1 supplement update and it has a build.prop file in it. Reinstalling it would likely get you running again as long as you haven't made any other significant changes to the system files. It might revert a few system applications to older versions.
If you have adb set up and working, restoring your backed up build.prop would be trivial job. Let us know if you have adb working and then we can give you the commands you need to use.
As of right now, I do not have adb setup and working. Well, that's not quite true....I did set it up quite some time ago and used it on my Droid. Guess I need to reconfigure it for the gtab and then proceed from there?
Joe
Well, I resolved my issue by reflashing the VegaN rom, all is good now.

Okay, I'm starting a new thread for this because the sticky for the nookandzergy script means this issue gets buried. After using Unroot app and factory resetting, etc. I think I'm unrooted. There's no su, there's no superuser, etc. My problem is that now I cannot use the rooting script. The nookandzergy script will see my device, but says it's not a nook tablet (I do have android composite device in device manager) because it can't find my build.prop. It will then reboot the device. I'm using win7 professional. I have system restored to before the install and still no dice. I'm afraid something is damaged now or missing permanantly from my nook. I just want to run the debloater and gapps install. Also, nook tablet has a hard time opening apks as well. I can manually root using the instructions in the thread but cannot use that script for the life of me. I've also tried multiple times to reinstall the driver files and can do that successful, but almost always end up with mass usb storage. Uninstalling that does nothing to help the device run the script.
This device is a huge pain. I think if it at least behaved like a normal android device it would be much more enjoyable. No back button, etc. Homecatcher as well doesn't play nice with my device either since I successfully rooted it once.
Here is the NT build.prop file in case you need it. Remove the txt extension from filename. That is how the file was attached in the GApps forum.
Here is the thread to make /system readwrite post#2
http://forum.xda-developers.com/showthread.php?t=1396864
Put build.prop in /system if missing. Reboot.

This is a question, not development. In the general section please!

Wifi and OTA updates were working fine before I rooted my kids' Nabi 2. I never tried an OTA update until after I rooted them, which doesn't work (I tried 2.1 since it said it was available). I followed the directions at http://forum.xda-developers.com/showthread.php?t=2041224 and it worked great to restore to stock 1.9.12, but wifi doesn't work now (mine could have been 1.9.37 originally). I tried the "wifi fix" mentioned, but there are still no wifi networks displayed like there were earlier today. I do not have a micro SD card to install the updates from, as mentioned in the replies. If I were to buy one, can I just put the OTA updates from http://forum.xda-developers.com/wiki/Fuhu_nabi_2 on it, and install from it somehow?
I tried to copy fuhu_nabi2_138139_1937_ota.zip to the device and install through the recovery kernel, but got an "assert failed" error. Any ideas as to what can be done to at least update this to 1.9.37, or maybe do a "stock install" of 1.9.37 instead of 1.9.12 so I have a better chance of wifi working? Please be specific as to what I need to try and in what order...some of the tools I tried seem to be inconsistent in results (Nabi Lab was latest I used). I am comfortable using what t499user has to go back to 1.9.12, I just wish I could use the same method to go to something newer...
I had the wifi problem this past spring. I backed up all my apps and data then flashed back to stock with NabiLab. Re-rooted and all was fine again.
You should also be able to use TWRP to flash back to stock. See TWRP thread http://forum.xda-developers.com/showthread.php?t=2074501
Some more info that may help http://forum.xda-developers.com/showthread.php?t=2248495
This experience is only my second time with TWRP and updating the Nabi. I've previously tried reverting to the backup in the "stockunrooted" folder, which is where I think the original was. I now recall that this had been updated to 2.0 using OTA before it was rooted.
Using TWRP, I tried reverting back to stockunrooted just now. Wifi works again, but OTA still does not (2.1 downloaded and seemed to install quicker, but upon reboot all I saw was "an error installing" message and it went directly to TWRP (where I just rebooted and it went to the Nabi screen). I am not sure what else to try. There is also an "oem" folder available for restore in TWRP, but that is the one created using t499user's process to go to 1.9.12. I initially used t499user's tutorial because I thought maybe something was wrong with the stockunrooted backup.
I have a few questions. Is updating TWRP to the latest version important? If yes, how do I do that (I've seen http://forum.xda-developers.com/showthread.php?t=2074501 before, but still not sure how to download/install 2.6.1.0)? If this has been reverted to "stock" and OTA updates still don't work, how do I apply them manually (from http://forum.xda-developers.com/wiki/Fuhu_nabi_2)?
I just noticed that the "stockunrooted" backup has things that aren't stock. Internal Storage has an Android folder with com.google.apps subfolders, etc. I am back to the original problem, and that is going to "stock" (something other than 1.9.12).
Cool, I figured out how to install 205to210.zip (TWRP 2.3.3.0)...For anyone interested, I copied the zip to Nabi/Internal Storage/TWRP, booted while holding +, pressed - to 'recovery kernel,' pressed + to choose it, then chose install. There is one more update I tried (2127stock.zip), but I get a flash error and it did not install. Considering (so far) I cannot get back to "stock unrooted" and use OTA updates, does anyone know how I can install this?
Wait...maybe there isn't another update. http://forum.xda-developers.com/wiki/Fuhu_nabi_2 has "Update 2.0.5 to 2.1.27" as the latest. I think it is working OK. Back to my original question(s), what is the process to install an updated version of TWRP and a "stock version" of something other than 1.9.12? Just trying to get the whole process understood...If I can simply use t499user's tutorial with different images, that would be rad to the max.

Yes its probably wise to update to TWRP 2.6.1.0. Get the file

As for getting a stock image. You were using the zips here http://forum.xda-developers.com/wiki/Fuhu_nabi_2
You dont "Install" those zips. You need to extract the contents. boot.win, system.win, etc. and put them in the TWRP folder.(TWRP/BACKUPS/XXXXXX/folder)
Make a folder called 2127 put the filed in there. Then "Restore in TWRP. Then you should have a stock system. Same goes for 1937stock.zip 205stock.zip
If you have questions ask away.
Thank you all! I think I am getting it. Since I am reading (and had first hand experience) that Google Play isn't working very well with 2.1.27, I will go back to 2.05. That should keep the kids happy. I will let you know if I have more questions.
Oops...I broke something. I have two Nabis. I accidentally restored one using the device ID path of the other. I used "adb push c:\nabi\fuhu_nabi2_v1912_system.ext4.win /sdcard/TWRP/BACKUPS/015d2bc264340217/oem/system.ext4.win" for both. The incorrect one booted, but I noticed that the apps aren't the same. I tried to use TWRP again, but it is not recognized by cmd "adb devices" and I get "error: device not found" when trying "adb reboot-bootloader." I also tried whatever restore option there was in the settings, but it is the same result...Any options?

Google play won't work with 2.1.27 unless you delete some apps from /system/vendor/apps before installing gapps
As long as you have the bootloader(with the 4 options boot normal, fastboot, recovery kernel, forced recovery) and working USB port there are always options.
So is ADB not working in TWRP or in Android or both? It's probably best to copy boot.emmc.win, data.ext4.win and restore those too since you have done so much stuff. Boot contains you kernel, and data the apps. You will be back to a stock tablet with no game saves or anything so make sure you got off the tablet what you needed
I don't see a /system/vendor folder using TWRP file manager now...is that only when 2.1 is installed? How much do I need to remove, and are there any known problems with gapps in this case?
I fixed whatever problems I had. (Yes, I still have the bootloader.)
I am not that familiar with this, but let me explain what I have done. As before, I was using ADB/fastboot instructions from http://forum.xda-developers.com/showthread.php?t=2041224 (Windows 7). Both tablets' Internal Storage were recognized by Windows, but only the other one (with correct device ID 015d2bc264340217) was recognized when using ADB. That is how I was updating between Nabi 2 versions before.
Tablet 1:
C:\adb>adb devices
List of devices attached
015d2bc264340217 device
Tablet 2 (normally 015d24a7f41c1c15):
C:\adb>adb devices
List of devices attached
At one point, both devices started an endless loop when booting (shows the "Please wait while Nabi initializes" message for a split second and boots again). It may have been something with the way I installed the OTA updates, but I figured that it had to be something wrong with System so I wiped absolutely everything from within TWRP and I followed t499user's instructions for Windows cmd line (for going back to 1.9.12). Everything is good now, but I don't want to upgrade to 2.1 if gapps has any problems...

Before browsing with TWRP file manager you need to go to the "Mount" tab, put an X in system. Then go to file manager.
Probably have to remove around ~50MB, maybe a bit less. Lots of people choose Wings, but obviously Wings is something some kids love. Really depends on the user.
When you flash stock, it often reset USB debugging to off in Android settings, if you flashed data too.
USB debugging is still on. Do you know anything about whether or not gapps has any problems with rooted Nabi 2.1? You have been a great help!
I didn't realize what would happen until it broke, but what I tried to do was remove apk files prior to upgrading to 2.1. I have copies of them on Internal Storage and locally, but I don't see a way to copy them back to /system/vendor/app using TWRP (tried mounting everything except external storage, which isn't selectable; internal storage isn't selectable, located to the right). Is there a way to do it, or do I have to go back to 1.9.12 and start over?

The only problem gapps has is there isn't enough room for it with a stock 2.1. You have to remove something.
Mount everything in TWRP. Go to file manager. /data/media is internal storage. You will find your files. Copy them back to /system/vendor/apps. Might have to set permissions.
Thanks! I copied from Windows using adb, but I got the same asset error (two of the files no longer had their original icon, it was default Android icon). That might have been the permissions issue you mentioned. In the future, how do I change the permissions, and what should they be set to? After this, I am done messing with it. Thank you for everything!

You might be out of space again depending on what you copied back and why the icons are blank. Check with
adb shell df (in Android)
Look at system and see how much space you have free.
Or it could be permissions. You can use a file manager in Android such as ES File Explorer or Astro. You need to go to the setting in the app and enable whatever option they have to browse and remount "system" as read/write that will require root and should prompt you to accept. Then you can browse to the directory. You could also use TWRP File manager the same as when you copied files. There is a permissions tab.
I think the permission you want is 0644(for TWRP), or wr-r--r--(for ES). Same thing just different nomenclature.
Similar issue as OP
Hi guys, I have done pretty much the same thing as the OP. The wireless will not turn on or find any networks. I have tried reverse tethering, but have lost root and pretty much any other way to get internet to the nabi 2, so I can update from version 1.9.12. The big problem is I cannot use TWRP because when I boot into recovery and try to get there I get the dead green android guy with the exclamation point error and it hangs there until a hard restart. Any ideas on how to fix this. Is there a way to push an update through the SD card? Any ideas and suggestions would be greatly appreciated. I have already spent more time than I would have liked trying to fix this.
Dead android is stock recovery. You need to reflash TWRP.
Also to get out of the stock recovery just press vol + and - together. Should be am option to reboot. No need to hard power off.

Well I swear I have tired this, but decided to give it another go and it worked! Got TWRP up and running then ran NabiLab to return to stock 1.9.37. Wireless is working and updating to 2.1 and then will give root a shot and GApps. Thanks for getting back on track!
Hello everyone,
I use an LG Optimus L4 II (e445). I rooted it but then decided I had too much on it and decided to restore to factory settings. It all worked fine. However, when I got to the Google Account sign in page, it gave me the "couldn't establish a reliable connection to the server" error message. I followed every single tutorial I could find online as to how to solve this. None of them worked. Eventually, I re-rooted it (using VRoot) and managed to download an apk of ES file explorer and locate the hosts file. This had one line that shouldn't have been there:
127.234.104.240 android.clients.google.com
From what I can make out, this is the address of google's sign in servers. So somehow (I suspect malware/dodgy rooting program?) my hosts file has been edited to stop me logging into google. Restoring the device does nothing, neither does unrooting/rerooting. When I open up the file in ES (when rooted) and edit out the bad lines, I can't save for some reason- I think the /system folder is write protected.
So I tried to make the /system folder writeable. I used the android sdk to do this (mount -o command) but this did not do anything. I downloaded the mount /system apk and installed that, it did not help either. I tried /pull and /push on the hosts file to edit it and send it back using the apk. I could successfully pull and edit it, but it would not let me push it back. I'm kind of stuck here. I can effectively not use my phone- I can't use most apps and can't download any, and have no other solutions up my sleeve. Any ideas?
Thanks a lot,
Louis

After trying for a few weeks now, I've still had no success. One idea has come to me though- installing a rom. Would downloading a custom ROM change my hosts file? Also, if so, could anyone recommend one that is similar to default android? One last idea that I've got at the moment is sonehow completely wiping the hard drive of the phone and reinstalling androud on it, though I have no idea whether that is even possible, and if so, how to do it. I would really appreciate some help here!
Thanks again,

After reading, I can only talk as one who knows less than you.
Let me say this from the start.
Root=/= unlock bootloader
Find a way to unlock boot loader first, with a Google search.
Use fastboot to flash a recovery (.IMG) made for your phone. fastboot is something like adb.
Let's just say that that is more complicated than rooting. It gave me a headache at first.
_______/
Pertaining to your problem, how about a reflash of the system image?
The official lg mobile support tool may help you with this.
Search for your phone model on the lg support page, look under manuals and downloads, then under software update.

I'm not entirely sure I understand you here, but I'll try. What would unlocking the bootloader do to my phone? Would it enable r/w on the system folder? Also, what is a reflash of the system image? How would I do that?
I'll try these things if I can, but would still appreciate help.
Look around on http://wiki.cyanogenmod.org/w/Basic_concepts?
It should give you some info in flashing and unlocking.
It can give people quite a headache, with all those terms.
________
As for the part under the line, I'm talking about a restoring of the phone to the default state via official methods.
Instructions would be given by the official support programme.

Ok, so from what I can work out, cyanogen does not support my device. Would doing it for a similar device work? Are there any ROMs that support my device?
under the line, restoring the phone via the official ways actually just wipes the user data, not including the HOSTS file which is what I need to wipe. What I really need it is basically a ROM that completely wipes my phone and reinstalls some version of android.
Any other ideas?
While there may not be official support for a phone for a custom ROM, you may be able to find unofficial ports/versions if you search for it in the forums.
From what I know, a system reinstall via official methods wipes data and almost everything else, then downloads from its servers system files to be installed to the phone. At least, my phone was reverted to a stock ROM when I restored it after using a custom ROM. It may be different for some, but generally, this is what I think.
Important: only use a ROM made for your device model only, do not use the ones made for a similar phone, the small differences are no longer small in this case and will cause a system error(?)
Generally, once you have successfully unlocked boot loader using a method for your phone, the instructions afterwards are generally the same for all phones. You'll be able to get better answers in the threads specifically for your phone, so try to look for one and look for the already tried methods,
Here's one:

Hi there, i've been trying to make some changes to my build.prop (mainly enable miracast...can't believe they would disable it!) and i've had a rather challenging time.
I am now stuck on how to pull the actual build.prop...when i enter the command i get a long list of ADB definitions but no file - at least not that i could find. I tried a few times, including directing the file to be saved on an empty drive in case i could not see it.
I have unlocked my boatloader and installed TWRP. Mounted the system then gone back and entered the commands in ADB....and i don't seem to be having any success. Any help would be appreciated.
thanks

Why not just edit it within the built in editors in most file explorers? I use Solid Explorer and it allows me to edit at will within the app itself, no pushing or pulling. Of course I back up my current one before doing anything to it

You won't get OTA with twrp either. You need stock recovery.
so i bit the bullet and rooted my phone...i was able to get the build.prop editor to work (at first i did not have busybox which it seems helps apps to realize you have root). So now when i go to unable Casting, i can turn it on from the top right of the cast screen, and my tv appears. I can select it and it starts to sync up...then the mircosoft display adapter shows that it's also trying to sync...and then it times out it seems. I've checked it with my tablet and my wife's phone...both work.
any suggestions?
I understand Miracast no longer works in Nougat. I'm still on MM with my 6P and it works, but if you're on 7, you may have lost that feature.
What about WUGS toolkit? Do you need to re rooted for that...ifnot thats what I always use to edit the prop. So much easier as it has most edits you'll make and you just choose.
you never needed to root i edit build.prop like this all the time
1. boot to twrp recovery
2. go to mounts and select system
3. adb pull /system/build.prop
4. make edits
5. adb push build.prop /system/
idk if your edit will work but thats how to do it without root and for some of the other things said in this topic you can ota in twrp but it will fail if modify anything like you just did
Hello there,
I'm wondering if there's anyone knowledgeable to point me in the right direction. Coronavirus (or I) messed up the build.prop file in a Chinese-made JTY-K107 (MT6580 architecture) tablet and now stuck in a soft-brick state. I cannot use adb push or adb sideload (doesn't detect device probably because I had attached another MT device, a Huawei on the PC before and that is the device I pulled the build.prop from to mess with the bigger tablet and now all seems jumbled driver-wise on my Win 10). In any case, I am able to copy to the SD card an update.zip but factory recovery installation is not possible ("installation aborted" - signing issue?). I tried these two zips inside which the original build.prop files are now nestled. It's maybe the commands/scripts that are at fault or it's some signing issue (that hopefully can be tackled). I don't know. I am very reluctant to think about flashing ROMs at this stage. (Porting MT-architecture ROMs are not exactly easy or risk-free, from what I have seen around other threads/forums.)
The link to the folder with the non-working update zips I pulled from other sites or threads (not knowing how I should go about building these files from scratch on my own):

Thanks very much for any info (or possibly a fix of the zips to make it compatible with MT6580 to install the update).
Cheers,
Zoltán

IMHO a simple factory reset may solve your problems.

Today I was thinking, people like overcomplicating things: there must be some easy solution. I actually had done that out of frustration (knowing that I had a Titanium Backup on SD) but the boot issue persists (I tried again but all I see is the Android logo for minutes now).
I thought maybe there was a way to repackage my full Titanium Backup into a zip that could be used in Factory Recovery for a restore solution? I perused the net in vain for that too.
I really don't fancy reinstalling Win 10 to fix the driver issues or trying on one of my Linux machines (I am a noob on those too).
Thanks for the answer, anyway.
In the end I managed to restore the tablet (took me 2-3 days of looking around). I'm only writing this up so others facing adb probs can solve their issues on their MTK-built devices. (Actually probably this will work on any device that is not Samsung or whatever old famous brands.)
The first thing to do was sorting out VCOM drivers. There's a Nigerian-sounding guy whose forum Hovatek I followed for tricks on how to go about it (had to download and install Virtual Serial Port Driver to sort out connection issues in Miracle Box/Thunder). Whenever you have some problem, I suggest you include Hovatek in the search string, cause chances are he has a tool and a tut.
Using Miracle Thunder and acting on Hovatek's instructions I made a copy of my firmware. All I really needed was the sytem.img, of course. My bootloader being fine (messing up your device with build.prop only results in a soft brick), it didn't need fixing. Using Assayyed's Kitchen and Hovatek's tutorial again I unpacked the system.bin I extracted with Miracle (which must be all the time used with virus protection off) after renaming system.bin to sytem.img. I exchanged the build.prop and repacked system but didn't wait for the update.zip to be made, instead I took the img file I wanted in the Kitchen. Then tried SP Flash tool to flash system.img on the device but I had issues with the scatter file. So I downloaded a firmware from Boycracked or whoever and used that scatter (in the meantime I overwrote the system.img with mine). I flashed device, turned on the tablet and voila. I hope this helps peeps out there with similar issues.
