Yesterday I received ICOO D50 Lite, it was loaded up to the 2nd image on the display (first green android in the next picture the name of the device). Livesuit not reflash, clamp the back button, insert the cord and few times press the power button, the system will see the device, put the driver and all - there are no familiar pop-ups, livesuit not see him, as if I chose the firmware for another tablet.
Next Im setup CWM recovery for Alwinner A10 devices, one of the courteous users of this device (d50) is also setup recovery and made a firmware backup.
I thought that the problem is solved, but device refused to restore the firmware (on another tablet recovery work well).
First, it is cursed in exec '/ system / bin / sh' failed: No such file or directory (2), I unpacked the folder system and downloaded to the tablet via adb.Then he did not like the sum of md5 hashes, which I also cleared. The next time checking md5 sums is successful, then erasing boot before restore, restoring boot image, restoring system... and then an error error while restoring system!
Changed the adb driver to bootloader (too late realized that, this is my first experience with adb), but now the device does not boot up to the 2nd image and bootloader, and freezes on the first picture with android and in the system at this time is not defined as the adb \ bootloader . That is my sad story.
Send it back or possible do something? I hope for the bright minds of this forum. Thank you all in advance. Sorry for my english.
Everything was decided uploading the latest firmware, livesuit successfully identified the device. Earlier this could not do because their site did not work.

Fuhu Nabi General information
1. Introduction
It was only recently that the Nabi2 got it's own forum. This device has been out a couple of years so the information you may be looking for is spread all over XDA. The largest single chunk of information resides in the Nabi 2 Root and Gapps Install by jmz, the problem is that thread is now 265 plus pages and mostly impossible to search. What I find more troubling is that the methods in which we go about root, modding etc evolve over time and newer users are using methods and tools that are now obsolete and can create more issues then they solve. Also while the moderators have done a wonderful job, not every Nabi thread is here in this section of the forum so I wanted to link to those that are pertinent.
While this is a Nabi2 forum I personally find it a better use of this corner of XDA to discuss all Nabi products, and this information post will discuss them all. Nabi JR, Nabi 2 Original, Disney and Nick, Nabi XD, Nabi2S, Nabi Dreamtab(Intel and Nvidia) , Nabi BigTab 20" and 24".
Most of the discussion will be catering to Microsoft Windows users as it is the most common usage scenario. It also will be light on discussion of the Intel version of the Dreamtab as it quite different.
Also look at the wiki. Information is very dated but there is some useful stuff, be careful with what you are flashing as the wiki is more informational then current methods. I would recommend asking before using any of the scripts or programs. http://forum.xda-developers.com/wiki/Fuhu_nabi_2
2.Basics
With the exception of the Nabi Dreamtab by Intel (DMTAB-IN08A), all the Fuhu Nabi products are built on Nvidia Tegra2, Tegra3, or Tegra 4. Therefore most methods of modding, recovery, etc are similar with a few device specific difference. The main utility we use is a custom recovery called TWRP, if you have come from other devices you might have used CWM, Odin, and countless other utilities, TWRP will be accomplishing the tasks on the Nabi devices. All the Nabi's already have a "stock" recovery on the device. It is useful for taking OTA(updates) and factory resetting but it's limitations end there, and this is where the TWRP custom recovery will come in to play.
There are 4 modes of operation for Nabi's
Each mode offers different usage scenarios and you should familiar with what they look like and which one you are in.
-Android
-Recovery -
-Bootloader/Fastboot
-Forced recovery/nvflash/APX
Windows are driver can be a pain but necessary before you can do anything else
No matter which method you choose or need to use the Windows drivers must be installed on your computer before you can do anything, without getting that setup nothing else is going to matter.
Most mods, rooting, and recovering devices and are done by one of 2 methods.
-Tool/Script - This is usually done by a GUI/Command prompt tool where the user clicks a few buttons and the magic happens in the background
-Manually - This is getting the hands dirty method, typing command lines, moving and unzipping files and is unfortunately common as there aren't many of the tools/scripts mentioned above.
3. The 4 Operational Modes
1. Android Usage: ADB and File Transfer.
-The normal operational mode for the device, and why you bought the tablet. ADB is NOT enabled by default, you will need to turn it on to perform any ADB operations. To enable ADB on the device:
-Login to parent mode
-Open Settings and see if "Developer Options" is listed if not
------Go to "About tablet".
------Click on Builder Number 10 or so times.
------Eventually you will see developer options are enabled.
-Open Developer Options and turn them on in top right corner
-Check the box USB debugging
-When using ADB on newer software builds when you execute a command the first time you will need to authorize on the tablet the first time, you can prevent this pop up by checking the box to always trust your computer.
2. Bootloader Usage: Fastboot. Booting to recovery. Booting to nvflash. Installing TWRP or stock recoveries.
Allows selection of other 3 modes, and utilizing fastboot commands.
How to enter bootloader/fastboot mode:
Device powered off:
-Depending on device press and hold the power and vol - keys OR power and vol + key. Some will boot straight to recovery, and others will come to the "bootloader" screen. We want the bootloader.
-To enter fastboot use vol+ and vol- to highlight and select fastboot protocol. (Device will need to be plugged in to computer and fastboot driver installed before the screen will change)
Device powered on:
-Use ADB and execute from the command line: adb reboot-bootloader
3. Recovery Usage: ADB, File Transfer, Installing Mods and Root, Recovering backups, Recovering Device.
There are 2 different versions of recovery. "Stock" and "TWRP". Stock is what comes with your device, and can be identified by the "dead android" picture when it boots up. Stock recovery is rather limited so if you see the "dead android" know you have stock recovery on the device. The 2nd possible recovery is TWRP, and the one used for most things you will be doing. It should say Team Win Recovery Project, or TWRP when it boots up.
How to enter recovery mode:
Device powered off:
-Depending on device press and hold the power and vol - keys OR power and vol + key. Some will boot straight to recovery, and others will come to the "bootloader" screen.
-Use the vol + and - keys to select recovery kernel. (one key will highlight the selection and the other key will "select" what's highlighted)
Device powered on:
-Use ADB and execute from the command line: adb reboot recovery
4. Forced Recovery Usage: Last resort for recovering dead tablet, heavy duty modding.
Rarely used. Can modify tablet, and prevent bricks. Only useful on Nabi2 Original, Disney, and Nick.
How to enter forced recovery mode:
Device powered off:
-Depending on device press and hold the power and vol - keys OR power and vol + key. Some will boot straight to recovery, and others will come to the "bootloader" screen.
-Use the vol + and - keys to select forced recovery. (one key will highlight the selection and the other key will "select" what's highlighted)
-screen will be completely blank, you will also need a windows APX driver to communicate with device.
4. Drivers
The windows drivers are problematic. There can be conflicts with other drivers, or just not found for the Nabi, or 64bit driver signature enforcement. As previously mentioned to utilize almost any operation for modding/rooting etc. you must have the drivers installed. None of the manual methods or auto tools are going to work if you don't get this accomplished.
It most cases you will only need 2 drivers. ADB interface and Fastboot/Bootloader Interface. The 3rd will only be needed on the rare chance you need to use the APX interface. What is important to understand is your computer will only see the interface that is used depending on the "Operational Mode" the tablet is in. For example if you are in Android or Recovery your computer will see ADB interface but NOT the fastboot interface. If you are in the bootloader interface(and have selected fastboot protocol) you will see the fastboot interface and NOT the ADB interface. So to install both drivers, you will have to boot to Android or Recovery and install one driver and then the bootloader to install the other. The order in which you do this will depend on which operational modes are available to you depending on the health of the tablet. (The same would apply if you need to use Forced recovery, you will need to be in that mode to install the 3rd driver APX interface, again this is rare)
Device Manger is the best way to see what is happening. With your tablet plugged in to the computer open device manager and look for either yellow ! or ? or something under the tree for "Android Device". If you are seeing the yellow ! or ? for your device then likely the drivers are not installed.
There are a few drivers and methods that seem to work best for most users. One of the bigger issues is 64bit driver signature enforcement. Windows Vista,7,8, and 10 do not like to install drivers that aren't digitally signed. There are 3 drivers that I am going to recommend. 2 are digitally signed drivers and there other is not.
PDAnet: I really don't like recommending this but it seems to work in most scenarios. Remember your tablet will have to enter both modes to install both drivers and remember that ADB will not show up by default in Android unless you enable it(see the operational mode section above)
http://pdanet.co/a/
NabiLab drivers: These are digitally self signed by me. That will require rootCA to be installed. This could create a security risk if someone was to steal my signing key. If that worries you don't use them or uninstall the drivers and certificate when you are done.
http://forum.xda-developers.com/showpost.php?p=62826514&postcount=2639
Universal naked:
If you aren't technically savvy I would use these as last resort. It will require you to disable "windows driver signature enforcement"(google it because it depends on windows version). Extract the zip package. Enter device manager and find your device, and manually update driver by pointing to the folder you extracted the zip.
http://forum.xda-developers.com/showthread.php?t=2263822
5. Tools and Automated scripts.
There aren't a lot of current tools available. They have mostly aged beyond their usefulness. The reasons are quite a few.
1. As the Nabi's upgrades the Android software from Ice Cream Sandwich to Jellybean to KitKat, the bootloader also changes. This changes how TWRP is able to see the internal storage and usually it can't. An Ice Cream Sandwich bootloader needs to use a TWRP for that version. For example the original Nabi2 has 3 different TWRP versions for the 3 different bootloaders. A lot of the older tools were made with a TWRP that no longer will work with your device. This will show up as TWRP "unable to mount" errors, and therefore the tool/script will fail for that reason.
2. Gapps. Originally many Nabi devices didn't have a Google Play store option. A lot of the tools still work on that premise, but most Nabi's have Google Play now. Google Apps also change with the Android version. So the tools can make mods based on that old information will cause problems.
3. Super user. A lot of older tools with "root" scripts don't have a current super user(root) binary and daemon. Newer Android version need a more up to date Super User install. With this situation you won't cause as many problems but will not good root with the script like you expect.
I will try to keep the list somewhat up to date
4. Mods. Like above, the mods that change your screen and/or add functionality, are heavily dependent on your android version, and will usually make your tablet un bootable if using an incompatible one.
Taking that in to account it's important to realize using old tools will cause you more issues then using no tools at all. I will try to keep the list some what up to date but in general there aren't many still usable tools.
The only tool that is even somewhat current is NabiLabGUI 2015, it can deal with quite a few of the Nabi products, and is at least very good at troubleshooting and has a command line setup that you can use to follow other users command line suggestions.
Get it here. http://nabtabhacks.com/nabilabgui2015/publish.htm
Here is the thread for the OLD version of the program. http://forum.xda-developers.com/showthread.php?t=2391449

Nabi BigTabs

Nabi 2S(newer Nabi 2 tablet)

If the tools aren't working your are going to need to do it by hand. See next section.
6. Setting up to do it by hand
Remember none of this is going to work if you haven't set up the drivers. Putting it all together now, also recall that you must be in the right "Operational Mode" to use either fastboot or to use ADB.
First of all I should mention that NabiLabGUI2015 has an option to work from the command line and has a lot of this already setup but to start from scratch:
When you setup the drivers earlier you got a driver for ADB and a driver for fastboot. Now to then talk to those interfaces you will need software to do that. Specifically an ADB.exe and fastboot.exe.
-Download and install this package(pay attention to where you install this as you will likely need to put files in there later): http://forum.xda-developers.com/showthread.php?t=2317790
-From your start menu select "Minimal ADB and Fastboot" this should open a command prompt where you can type commands
-If you didn't pay attention or forgot where you installed the files, at the command prompt that opens type "explorer ." The period is important, explorer <space bar> and a period. So type what is between the quotes.
Now you can drop and drag, unzip, etc the files you need in to that folder. You are done with manual setup.
For nvflash setup(Only for Nabi2 Orig, Nick, Disney NOT 2S, this step won't normally ever be required, and is only here for completeness)
-Download the nvflash.zip attached to this post.
-Make a new folder in the same folder as above and call it nvflash
-Extract the contents of the nvflash.zip in to the nvflash folder
-At the command prompt type "cd nvflash" to change in to the folder and use nvflash
THIS IS STILL A WORK IN PROGRESS
7. Getting TWRP on the device
The most common form of using TWRP is to install to the recovery partition of your device. Remember on certain devices(Nabi2 for example) the version of TWRP you use has to match the bootloader on the device, and the bootloader "type" will almost always correlate to the version of Android you are/were using. So if your Android ROM is Kitkat, the bootloader will be KitKat and you should use the KitKat TWRP. There are various tools linked above in the tools and scripts section that can install TWRP automatically depending on device or you can also use "dd" from Android to install it. In this section the manual method of installing will be highlighted.
1) To load TWRP we will be in the fastboot operational mode(see section 3)
Device powered off:
-Depending on device press and hold the power and vol - keys OR power and vol + key. Some will boot straight to recovery, and others will come to the "bootloader" screen. We want the bootloader.
-To enter fastboot use vol+ and vol- to highlight and select fastboot protocol. (Device will need to be plugged in to computer and fastboot driver installed before the screen will change)
Device powered on:
-Use ADB and execute from the command line:
Code:
adb reboot-bootloader
2) USB plugged in and Fastboot/Bootoader Driver loaded(see section 4) verify with windows device manager if needed.
3) Download the TWRP zip file for your device from TWRP list below(see section 8)
4) Extract the file to the location your are running your command prompt(see section 6)
-The file will be called twrp-recovery.img or recovery.img
5) Depending on the name of the file in step 4, load TWRP by typing at the command prompt:
Code:
fastboot flash recovery recovery.img
or
Code:
fastboot flash recovery twrp-recovery.img
On some device the bootloader is "locked", without unlocking the bootloader TWRP cannot be loaded. Unlocking the bootloader will erase ALL personal data on the device. If you see a message like this when trying to load TWRP:
downloading 'recovery.img'...
FAILED (remote: Bootloader is locked.)
finished. total time: 0.003s
You will need to unlock the bootloader with following command
Code:
fastboot oem unlock
OR
Code:
fastboot -i 0x0489 oem unlock

9. Recovering Bricked Devices
In this section we will go over recovery from non booting devices. I would classify non booting as one of three situations.
1) Tablet is being used normally and one day it has crashed or when restarted sits at the bootamination(spinning Nabi logo, Dreamworks characters)
If you haven't been doing anything but using the tablet normally then the most likely culprit is that some file is corrupt on the data partition. While there are ways to replace just that file if you suspect which one it is the simple solution is to try and wipe the data partition and start fresh. There are two ways to accomplish this:
a) Use the stock recovery if you haven't installed TWRP or haven't unlocked the bootloader. Boot the stock recovery using "recovery" in Section 3 above. Press both vol+ and vol - and the same time and you should get a menu where you can select to factory reset. This wipes ALL data from the tablet. When complete try to boot the tablet.
b) Use TWRP recovery from section 7 above. TWRP will give you some flexibility in that you can back up the data partition before you wipe it(in case the issue wasn't actually the data partition you can restore the data back), and TWRP will not delete "internal storage" if you do a factory reset.
-Boot TWRP
-<optional> Backup data partition to EXTERNAL sdcard(be safe and back up to external card not internal)
-<optional> While connected to computer backup the remaining files on the "internal sd" with windows explorer(Device should show up as an MTP device on later TWRP versions)
-Select Wipe tab and factory reset
2) You have installed a mod, installed a root application that has made a system modification, installed a zip file, or were just playing around swiping and wiping things in TWRP. Sometimes this will appear the same as above with a bootloop and boot animation that goes on forever.
a) Download the ROM for your device in section 10
b) Boot to TWRP (see above for instructions)
c) Do a backup of just the boot partition in TWRP.
- Click Backup tab
- Just check "boot" and nothing else.
- Swipe to Backup
d) Eject the external SD from the tablet and place in the computer
- Note: You should unmount the card from the mount tab in TWRP before ejecting it. (Uncheck the box next to external SD)
e) Connect the SD card to you computer
f) On the SD card navigate to the folder TWRP/BACKUPS/XXXX. XXX is a serial number unique to your Nabi.
g) Make a new folder and call in whatever you want. So it should now look like TWRP/BACKUPS/XXX/yourfolder
h) Unzip the ROM file you downloaded in to the "yourfolder" you created above. The files should look like ext4.system.win, emmc.boot.win, ext.addon.win, etc. Inside the the "yourfolder" directory.
i) Download the bootloader zip for your device from section 10
j) Copy it to the external SD in a location you will remember. This will be for the bootloader update.
k) Eject the SD card from your computer (safely eject it)
l) Install SD card in Nabi
- After inserted in tablet go to TWRP mount tab and check the box to mount the SD card
m) Go to restore tab, and find the backup under the "yourfolder" you made and unzipped the files to.
n) You should be able to select boot, system, and addon and skip the others.
o) If everything restores then go to TWRP install tab, find the bootloader.zip you downloaded and install it.
p) Reboot

Which ROM did you reinstall? What version 1.3.7, 1.3.12? Have you tried doing a tablet wipe/factory reset?(obviously you will lose everything on the tablet)

I tried both the 1.3.7 and 1.1.12 with boot loader 137 and still no success..
Before I did all that reading and trying I first tried the factory reset but the tablet still didnt boot so i went on to use the twrp tool and follow the instruction here in the forums but still no luck..
I also did some further research and from what i understand it appears that the firmware is what i need to flash so i open up the tablet and try to use the board id and processor type to find it but no luck.. (not sure if i needed to do that but since the twrp didnt work i tried another method) its the dream tab NVO8B..

All very nice, but will there ever be tips for doing this stuff on Linux? We do not run MSWin in our household. Granted, it will probably be a few months before I once again try rooting/flashing the Nabi2S, so there's time for the Linux methods to come out if they ever do.

I'd be interested if it helped to format system and data in TWRP before the restore next time.

Most of the time the commandine stuff is still the same when it comes to fastboot or adb. A lot of the scripts are easy to modify for linux.
Android keeps restoring all apps
I've got the NabiLab 2015gui, wiped and restored the Nabi2 to 3.0.13, installed twrp through it. I've flashed to the MinimalNabiWipe.zip, and rebooted and it goes right back to please wait while android updates 117 apps. I also can't get it to accept the changes recommended at trendblog.net/fix-kitkat-sd-card-write-restriction/ (which I had found while reading through 50+ of the most recent pages in the Nabi 2 Root and Gapps Install thread, it throws a generic error that it couldn't save. Any ideas?

I would check to see if you have .odex files that are orphaned. If minimalnabiwipe.zip deleted the .apk and leaves behind the associated .odex file what you describee will happen.

Can you point me in the direction of the .odex file locations? As I did a look around all the folders I could find in twrp and couldn't find .odex.

You are correct, I ended up removing "es file manager" and installing "total commander file manager" as it would do it for me.
hi all
I appreciate the awesome write up to help get this done.
I am having trouble, though. I am going thru nabilabgui. I get as far as rebooting below and then nothing happens when I hit a key. It appears that the nabi also freezes on reboot. Not sure what is going on. I tried going thru the manual method and seem to be confused.
Anyway, I would be happy to provide more details to help with this. Any help is appreciated, thank you.

You don't mention what device you have? I'm guessing Nabi2 of some sort, which particular model? Judging by the log it seemed to have written recovery, at which point is it hanging? The way I had to write it as windows app and emulating a command window(so if I ever stopped updating the GUI program someone could edit the batch files on the backend to do what they needed) I couldn't find a good way to end the script very gracefully(I'm not very strong at that language), but it looks like it finished normally.

sorry, nabi 2. thanks! so the next step would be flashing a rom?
It hangs at the end of the text there.

Thank you. And the program is awesome, no need for apologies about how it ends!

Are you trying to flash("install") the zip or extract the zip(system.win, etc) and restore? I'm not sure which part is failing for you. Which TWRP version?
Did you also do a factory reset after the flash?
Any one have scatter file I'm in twrp but it cannot mount any thing it says internal disc as zero I need to format it but cannot as Windows does not see it so if I use a scatter file try and flash it so flash tools
Any chance there will support for the Nabi Jr (new) soon? I made mistake of buying 2 from Amazon on t assumption that they were completely "hackable".
LOG IN Issue: It's Nabi 2 Demo Device I guess
Dear XDA friends,
This is Zeeshan from Pakistan. Few days back I purchased a used*Nabi 2 from*the local market here in Pakistan. The salesman gave this password to enter*into*the mommy/daddy mode "zxcv6789" which was working perfectly fine.
Then I thought of creating my own nabi account to enhance my daughter's Nabi experience. I registered through my own email ID,*which have*been working fine . However lately I decided to factory reset the Nabi 2 to improve its speed and performance, here is where I have been stuck from last so many days.
After the hard factory reset the tablet did not ask for setting up my Nabi account but it automatically logged in to the nabi mode and now when I try to login into to the mommy mode it says your password is incorrect, when I click on the forgot password link it says "An email has been sent to you. Please allow a few minutes for* delivery. ([email protected])" which seems to be nabi's own email ID and I am in a doubt that this device could be a store demo unit however when I purchased and before the factory reset it was working like a normal one, no demo nothing.
How can I fix this issue to login to Nabi 2 using my own registered email ID.
Following are the details of my Nabi2 device:
About this nabi
Account: [email protected]
Model No: NABI2NV7A-D
Android Version: 4.0.4
Build Number: IMM76L
Product Version: 1.9.23
Many thanks in advance.
Looking forward to any help.
Hello
My problem goes like this:
I started to deal with adroid devices not long ago, and it's the first problem so far that I cannot solve by myself.
Device is S8-50L model and here what happens:
Power On - stuck on Lenovo, powered by android screen, nothing happens.
Vol Down + Power on - Droidboot. When it starts on the bottom of the screen we have:
E:installer device ignored
FASTBOOT INIT...
E:Failed to mount device '/dev/block/sda1' as installer partition using fs_type 'vfat'
ition using fs_type 'vfat'
E:installer device ignored
FASTBOOT CMD WAITING...
E:installer device ignored
E:No valid installer medium found
Could not open /sys/devices/virtual/backlight
Ok, we can choose anyway between reboot droidboot, reboot, recovery, power off.
Trying recovery - droidboot comes again. No change.
I've researched and tried couple of things already:
-Repair bios
It starts and fails when it comes to [...]fastboot.exe" "-S" "150M" "-s" "INT78E84CC8" "oem" "wipe" "ESP"` command
Retry and fail. When it start flashing, windows pop up info about installing new device "Android MTP Device" and fails also.
Yes, I have drivers, because another S8-50 is visible and installed without problems.
-Flashing firmware from "FastBoot Starting..." screen (Vol down+up+power on)
It starts, and with command
Apply partition theme:
fastboot.exe" "-S" "150M" "-s" "Baytrail78E84CC8" "oem" "partition" "/tmp/partition.tbl"` command
It fails and stops. Every single time on 3 or 4 different firmwares
-Temp CWM
Says device is visible, when I try to launch it, let's say T3, it reboots and screen is black with hat and orange arrow icon on it OR complete black. Then nothing happens in both cases.
I've read also some russian topics about this tablet, but none really helped me in this case. What I started to consider - it's just somehow damaged inside, maybe eMMC, or else. Everything looks good tho, electronics are clean, no dry joints or anyhing damaged. Seems to be ok.
Maybe someone has and idea what else can I try to do with this. Even for science, since I'm beginner with andriod softwares and every experiment can teach me something new
Thanks in advance XDA
Hi all,
Well, operator error is definitely at fault here... I made a series of mistakes that got me to where I am now. All I intended on doing was repairing my dad's tablet which was running atrociously slowly. I tried to follow some steps, but improvised as I was getting errors and obviously ended up making things a lot worse...
Now tuning on the tablet will directly go to a command line interface with a long series of errors and these are the last 2 lines:
Rich (BB code):
blkD :HardDisk - Alias (null)
PciRoot (0x0) /Pci (0x17,0x0) Ctrl (0x0) /HD(14,GPT,80868086-8086-8086-8086-000000000008,0x646828,0x16D47D8)
blkE :BlockDevice - Alias (null)
PciRoot (0x0) /Pci (0x17,0x0) Ctrl (0x0)
Press ESC in 1 seconds to skip startup.nsh, any other key to continue.
Shell> _
In this state it cannot be interacted with and won't be detected by my PC over USB.
This happens for normal, recovery and bootloader modes. The only mode that I can access is DNX mode but attempting to boot droidboot will result in the same command line UI described above, including when trying to restore the BIOS using the PC executable (which I assume needs to enter fastboot mode, which it can't do...).
What can I do now? Any way to get anything working in the above screen or through DNX?
I'm thinking that a partition was corrupt in addition to me wiping the ESP is causing this. Maybe it's possible to completely format and setup all the partitions and start from scratch again? How can I flash esp.img when all I have access to on the tablet is DNX mode?
Detailed history below...:
HISTORY
1)
The tablet is a Lenovo Yoga Tab 2 1050F. It was running very slowly to the point where my dad just didn't bother to use it. I thought it would be wise to factory reset it as a first step. There is no option to do so within the Lenovo skin of Android so I started by going into recovery mode and performed a factory reset from there.
After it rebooted, the Android UI would loop back to the language selection after connecting to a WiFi network and I would get "Unfortunately Google Play Services has stopped." error message. It would just loop through the Language Selection > Connect to WiFi network pages over and over.
2)
Having installed CM on my old S3 back in the day, I thought I could go about the same process and flash a gapps ZIP file in recovery mode. That didn't work, I got an error because the zip was unsigned.
I thought I could install TWRP to flash unsigned zips, reinstall Gapps and get the tablet passed the Android UI loop.
3)
I followed this guide on XDA to install an unofficial TWRP (which involved unlocking the bootloader). It didn't work because I couldn't flash over ADB (because the tablet couldn't allow Developer Mode since it was stuck in the Android UI loop). So I flashed as many files as I could in fastboot.
I eventually flashed the TWRP recovery.img but that didn't work : when turning on to Recovery mode it would just go back to the bootloader screen.
4)
I thought I must have screwed up something up so I tried to restore the BIOS using an executable I found but I realized the tablet was already upgraded to Lollipop and the only BIOS restoration exe was for Kitkat. Sure enough it got even worse and I could no longer boot Android.
5)
I still had bootloader and fastboot though so I followed a guide to restore the tablet to the original OS (which ironically I already downloaded before trying to get TWRP but forgot about and didn't unpack). I set up Intel Platform Tools but the flash process didn't work because it went to droidboot and then lost USB connection. On the Intel program it would just stay stuck at 20% Wiping ESP. It would time out twice and then give me a final error message.
6)
So I thought to explore the flash.xml file provided to see if I could do the steps manually. I knew it was stuck at wipe ESP because in droidboot it couldn't get commands from PC. So I went into fastboot and wiped ESP manually myself! Little did I know how foolish this was to do because I was simply unable to flash the provided ESP.img again. Following this I lost access to the bootloader.
7)
I found a guide to restore a bricked 1050F here on XDA but it needs droidboot which now goes to the command line UI described at the top of this post. When attempting to restore the kitkat BIOS again, droidboot is also needed which results in the same cmd UI.
8)
Which leads me to where I am now which is that the tablet doesn't boot to: normal, recovery, bootloader/fastboot or droidboot. Which is why I am now asking for help. What can I do?
I'm thinking that a partition was corrupt in addition to me wiping the ESP is causing this. Maybe it's possible to completely format and setup all the partitions and start from scratch again? How can I flash esp when all I can get access to is DNX mode?
Thanks for reading this far and if you have any more ideas, please let me know, thanks in advance.
Hi, would anyone like to weigh in on this issue?
