Hello forums this is my first post,
I recently purchased a TF 201 used off the internet with ics so i decided to unlock it and root it then my bf tried to help me installed a custom mod and do to (lack of reading) the tablet flashed and is now stuck on the Asus splash screen and the only text is located in the corner saying the device is unlocked. We cannot access fast boot (any buttons at start result in the same result as just pressing the power button) boot we can only access apx mode and we do have NV flash but we don't have a blob file to use. He has the same model would it be possible to copy some files from his (I have access to windows and Linux)

You cannot use blob files from someone elses machine unfortunately.
Nvflash is useless to you without your own backups that could only be made while you was on ICS and working.
ok so then what

So then what are my options? Is there something soldered to the main board like a bios chip or something I can replace or do I have to completely replace the motherboard? Are there any other utilities that I may be able to use ?
Hello,
First off, I've gone through the forums and I have looked up other posts and despite everything I cannot figure out how to get my nexus 7 tablet to be recognized by the computer (I tried and after two days of searching for answers I decided to make a post). I like to include this information so people don't assume that I post without browsing or haven't tried anything yet.
The thing that I am having troubles with is that I have a nexus 7 tablet that is softbricked, I have already gone through a lot of ways to fix that problem (I found the best solution is this:http://forum.xda-developers.com/showthread.php?t=1809195). However, the issue is is that I cannot get my computer to recognize the nexus tablet to flash it and restore it back to factory settings.
I have installed and updated the device drivers on my computer, but still I have had no such luck. I found that ADB doesn't recognize the device whilst in the Bootloader, but still will not recognize the device in recovery mode. If anyone has any tips, or suggestions that might work PLEASE let me know, at this point I'm getting desperate and any/all help would be greatly appreciated!
Thank you!

adb is not designed to be usable in bootloader mode. You need fastboot for that. If you have the fastboot.exe program in the same folder as your adb stuff, try this:
fastboot devices
If it reads, then all you need to do is fastboot flash the various .img files back to the tablet. There are tool kits that do this for you, but I prefer doing it manually as there are less chances of things messing up and if they do, you're more likely to know at what step which could be useful for further troubleshooting if need be. It is important to download the correct img files due to differences between the generations and wifi / data enabled ones. There is a flash-all script that you can find in the download of the factory images, which might make it easier, but you can just manually flash the separate files as sometimes you don't need to bother with them all (like the bootloader) though if the script works, then it'll be fine and might make it easier if you are not familiar with the commands.
If you don't have fastboot at all, just grab it from here: http://forum.xda-developers.com/showthread.php?t=2317790

You won't get adb in bootloader mode.
You have to use the fastboot command.
Please tell the OS on your computer.
Use the tool in my signature as an environment.
Download 7zip, and install that.
Then go here and download the proper image for your device.
It would either be "Factory Images "nakasi" for Nexus 7 (Wi-Fi)" or "Factory Images "nakasig" for Nexus 7 (Mobile)".
Grab the 4.4.2 version.
Extract the downloaded file with 7zip into the "Work" folder in the tool form my signature.
Then extract that "nakasig-kot49h-factory-83d93b5f.tar" file with 7zip.
Then go into the folder that came out of that, and extract the "image-nakasig-kot49h.zip" into the Work folder.
And enter the following commands while in bootloader.
Code:
fastboot oem unlock
fastboot erase userdata
fastboot erase system
fastboot erase recovery
fastboot erase cache
cd nakasig-kot49h
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot reboot
Make SURE you grab the correct image for your device. Wifi or Mobile.
I also assume that you know the .img files should be in the Work folder before you type thse commands into my tool.
Hey guys, first of all thank you for the speedy replies and steps I should follow.
Right now I'm using OSX but for the tablet I'm using a virtual Win7 machine to try and get this damn tablet to be recognized by the computer. The process is being delayed a little bit because my micro USB cords are being temperamental, meaning that the tablet has no juice, and when I mess with it (using the power + volume buttons to boot to bootloader/recover) the cord comes unplugged. I know automatically you guys are going to pinpoint this as the source of the issue (mainly because I would too), but it works fine if just laid flat and stays connected. It just has zero charge so when it disconnects/reconnects I literally have to power it back up, just need to wait for it to have some charge before I tinker with it more.
I will post updates after it charges.
Although I already thanked you guys, thanks again for speedy reply. It's much appreciated.

I suggest to STOP!!!
If you are trying to restore the device and the cable disconnects in the middle of it, it might not be recoverable. That would be one of the few ways to really damage the tablet as they are pretty difficult to hard brick. Don't half ass it with stuff like this. A good cable is not THAT much and will certainly be cheaper than a new tablet or getting it to a point where you might have to send it somewhere for service.
I'm not familiar with Macs, but if you are more so, then this might be better than using a Virtual set up:

It's actually working fine now (in the sense that the computer can now read it). The Virtual Machine also works just as good, but for some reason the toolkit I'm using won't properly return the tablet to the stock image using the SkipSoft Android ToolKit, so I'm going to have to try and find another way.
Thanks for your guys' help.
Welcome to the comprehensive guide on rooting and unbricking your precious TF103C!
Some words of wisdom and truth
You will most likely be here because, you know, your device is bricked.
First of all, I would like to say that none of the downloadable links are made by me. I happened to find them laying around XDA after looking for a solution for a long time.
Skip this if you don't want to know the reason behind this thread
I got this device a while back (my guess is 4 months), and loved it from the start. Rooted it, of course, and soon after, it didn't want to boot anymore.
As there isn't much development going on (due to the locked bootloader), it's hard to find a solution for bricking. While scrolling, I came upon a post from member gouster3, which came to the solution below. I myself have used this successfully, and have my tablet back. In my opinion, also on rooting, there was no dedicated thread available that really explained the steps to root the device, so as a thank you to the guys who got my tablet fixed, here it is!
The rooting process
The rooting of this tablet is quite easy, really! I'll explain in a few simple steps.
Head into settings > security > then turn on unknown sources
Download the Rootzenfone .apk file. get it here
Install the app (if it is still in your notification bar you can just press the downloaded file, or you can navigate to it's location to install from there)
Turn on airplane mode before you open the app
Open the app, and hit "OK, I know, please root!" (when you press this, a number of screens and a popup will show, ignore those)
5 seconds after pressing, restart your tablet.
Hooray! You are now rooted!
Unbricking your device
Luckily, unbricking is almost as easy as rooting the phone, if you know the steps you have to follow. Here's what you could do (it worked for me) if you still have acces to DROIDboot.
As always, install the adb drivers first! get it here
# You can also make sure the correct driver is installed when plugging in the device in DROIDboot mode. In you device manager it should show up as Android Debug Bridge#
Download these files, containing a clean system. get it here
Make sure the device is turned off, and the battery is at least 50% (just to ensure a complete flash before your battery runs out)
Hold volume+ and power untill the asus screen pops up, then release the power button.
Plug in the tablet to your pc (usb cable) when DROIDboot has been loaded.
Open the downloaded folder, and find 'update_image.bat'
Right click the .bat file, and choose 'run as administrator'
A CMD screen should open on your PC indicating the flashing status. All you have to do now (assuming that it works as intended) is wait untill the process is completed.
Your tablet will reboot automatically when the process is done.
That's it! the 2 things that keep this tablet alive. I would like to send a thanks to the members who were so kind to help me out on this.
gouster3, for providing the link to the unbrick solution
Eclipse00, for giving the link to the rootzenfone apk
Monki, for giving me a clean system.img and putting effort into getting my tablet running again
To all of you, thanks!
It works on my TF103CX too. (it is same hardware).
When i bricked my TF103CX, i had around 80% of battery, but i was not able to charge,
so be careful when bricking. Always do interventions to system with full battery.
//I think, we need add our TF103C to xda device list. it will be nice.
I heared that using Intel Manufacting Tool we can get UEFI instead of Droidboot, and boot Ubuntu/Windows on IntelBay tablets. I found guide for Teclast: http://forum.xda-developers.com/android/general/teclast-x98-air-3g-tablet-9-7-2048x1536-t2913035 But i cannot find any UEFI fot TF103C. I dont want to full brick m device with trying flash it.
Here is original thread in russian language.
Thanks
Thanks for helping me rescue my tablet. Much appreciated
Could anyone please confirm if the rooting method may be used on the TF103CG (K018) model? Or in general is the app able to root any device that is anyhow Zen-related?
this don´t work if you have lillipop on tf103c, the droidboot don´t load, You only get Fasboot starting and nothing more...
i want the raw lollipop image ( system.img ) for tf103c
will this essentially work as a factory reset? mine touch isn't working; and i just want to nuke all my data off the device
Hello all, I just ordered a TF0310C (Best Buy exclusive) from woot.com which will be here tomorrow and the closest thing I can find information on is the TF103C (both are Intel processors), and just trying to find as much info on it as I can. I was unable to find any roms or anything for the TF0310c, will things from the TF103C work on the TF0310C such as rooting or custom recovery at least?

I know its a bit late, but perhaps better than never. I'd say those devices are identical, but somehow there is a weird naming mixup. Here are the official ASUS pages for them:
http://www.asus.com/supportonly/ASUS Transformer Pad TF0310C/HelpDesk/
https://www.asus.com/Tablets/ASUS_Transformer_Pad_TF103C/specifications/
Whatever you do on the first link, it will be eventually redirected to somewhere that belongs to the second. Their specifications are also basically the same. This is still a guessing game tough, so the best would be to compare 2 build properties, partition tables etc. of those devices to know more.
Rooting will most likely work, Zenroot should do it regardless of device type.
hello,
i have tried different way to unbrick my tf103c, but none is working
i have access to fastboot
i successfully run your bat file to copy the image, but after it reboot and stays on the "asus" logo
if i launch the command after modified the name of the "AS-TF103C-v67.43-capsule.bin" into "capsule.bin", it reboot then a blue progress bar is showing, when the bar is complete the tab reboots, but again it stays on the "asus" logo :'(
do you have any advise ?
Same issue
Hello,
I have the same issue with my tf103c ; i was trying to apply a new update from asus support (to get android 5).
It didn't work and in addition to that, my device results to be bricked.
I have successfully run the bat file, but then i get stuck at Asus logo and device never boot...
Icarolo did you manage to solve your issue ? Is someone really succeed in unbrick tf103c device ?
Thank you in advance
Dead
Hi! I have an asus tf103c and i rooted it with the rootzenfone.apk but now it doesn't turn on at all. after i pressed okay, waited about 15 sec and then i restarted it, but it just turned off. And now it's dead. What should i do?
ASUS K010 (TF103C). I forgot how to enter Recovery
Hello everyone, I have an ASUS K010 (TF103C). The complete model is TF103C-MB1-BLK-DK.
I forgot how to enter Recovery. My Asus is bricked. I know it is possible to enter the recovery because a few months ago I entered and also enter droidboot mode. On that occasion I discovered pressing the buttons energy, volume +, volume - somehow, because I did not work the methods that were in different sites websites, but now I do not remember the exact way of pressing the buttons. I tried many methods but they do not work, only the "Asus looking for incredible" logo appears. The battery has a charge (I charge it manually).
If someone has this same model and knows how to enter the recovery would greatly appreciate it.:good:
I think you can enter the droidboot menu by pressing Volume Up + Power for several secondes.
i dont have acces to DROIDboot.
How can unbrick my tf103c.. thanks

Unbricking tf103c
Hello,
Is it possible to unbrick somehow a device like mine. I dont have either bootloader or recovery or anything (I have two same tablets) and I mess one up. After new update touch screen stopped working so I installed something (I dont remember) i installed new recovery and then tried to install new rom...Every time I power it on (doesnt matter standar od with combos it just show asus logo in search of incredible and that's it. I managed if I press both VOL - and VOL + AND PWRBTN I get something in device manager "Unknown USB Device (Device Descriptor Request Failed)"! Is there anything I can do?
Hello. I'll try to explain my problem because I really need some help.
A few days ago, I was normally using my Tablet ECS TR10RS1 Intel®.... I turned it off, went to sleep and the next day when I was going to use it again, the OS didn't start, so I tried and tried until I found a forum where they led me to restore a backup file because the original firmware/rom wasn't still available.... publicly. I tried that, but in the process, I accessed the EFI Shell... That wasn't trouble at all, I just plugged the keyboard and typed "exit", and then it let me to the BIOS... And that's when my real problem began: I restored the factory setting default... and it involves "disabling USB ports".... Now, AGAIN, I'm stuck on EFI Shell. But this time, I can not type "exit" since the keyboard is not recognized by the Tablet.
Then I pressed Vol UP + Power ON and I get access to another menu "DNX".... And that's what brings me here to your forum:
I was briefly reading that one of your members managed to flash the BIOS via DNX, so I was wondering if you guys could help me do that to my tablet because I'm not planning to have a really expensive paper holder.
Thanks in advance.
Jinky.
Not sure about your case. But as your tablet use clovertrail chip like my zenfone 5 n fonepad7 170CG, then there's some methods to unbrick like via fastboot, flashtool, or intel factory flash tool... all of above are required a valid firmware, at least a IFWI package then intel FFT can unbrick anyway. So try to find your need, as i tried to help u to find it, but most of webpages use spanish, then i didn't understand anything

Hi,
I bricked my phone, a SHARP Aquos C10.
After unlocking the bootloader I was able to install several rom. The last one was LineageOS 18.
I bricked the phone when I tried to replace LineageOS Recovery with TWRP by dint of trying.
The phone is not completely blocked. It gets stuck for a long time on the "battery" logo which replaced the "Sharp" logo when the unlocked it. After several minutes, it vibrates and restarts.
I can restart it by long pressing the OFF button, I can't turn it off, I can't put it in recovery mode.
I can just put it in download mode but unfortunately it is no longer recognized by the PC.
So, bricked or not bricked.
Thank you for your help.
Nobody can help me ?
Hallo,
if you still can go to the download mode, maybe not all hope is lost. Your phone might not have
a hard brick, but only a soft brick. Everything should be fine as long the download mode isn't bricked too.
I had a similar problem once with a tablet after flashing it.
You need to install the USB-Drivers for your device on your PC and then reconnect it.
This might sound ridicolous if you already have installed them, but sometimes
a deinstallation of the USB-drivers and reinstallation of the drivers might help.
I found the following site for the drivers:
"https://gsmusbdriver.com/sharp-aquos-c10".
If you prefer an official source, you can use: "http://www.sharpusa.com/Home/CustomerSupport/SharpCareCenter/MobileSupport/ADBDriver.aspx"
However both sources seem to look reliable for me, even if I can't test it, without having a SHARP device.
If you are not sure, you might compare it with other tutorials and look for reviews.
Installing the drivers can't lead to harm to your device until you don't connect it.
Things can't really get worse if you install the drivers. The only thing that could happen is, that either the PC will say that it recognizes the device or that no device can be recognized, so it's worth a try. Please report me, if it worked for you and you are able to flash again. I hope this will help.
With kind regards
dontdropme
Hello,
Thank you very much for your help.
Yes, I installed the USB drivers. I unlocked the phone for you I installed another rom.
I reinstalled the drivers following your links. Unfortunately that does not change anything. The phone is not recognized. No sound comes out of the computer when I connect the USB cable.
I tried on 2 computers, 1 on Windows 10 and in Windows 10 / Xubuntu dualboot.
When the battery is empty and I try to turn it on, a red battery will light up and flash. As I charge it, the battery changes color to green.
I don't have download mode if the cable is not plugged into the computer or the charger.
:/
Hallo,
the download mode is supposed to be only able to get started if you connect the device to the computer or another device, this is not strange. You need to go to the download mode and try to flash the stock firmware for you device. Try it at first without a device recognition of your PC and find out, if you need to do a hard reset before, to regain factory settings. I have listed, in color, a short number of things you could do now. If this still doesn't work only the SHARP team or a specialized company might help.
What you could do, is to ask the SHARP support for a source for the USB drivers and how to do a hard reset to regain the factory settings. I don't know which flashing tool you use for you device.
Normally if your device is not recognized by plugging it in to the PC-USB-Port the flashing tool shouldn't recognize it either, but it might be just an error of Windows, and the flashing tool is not allways depentent to the USB-drivers, but relies only on the question if you can go to the download mode, so you could give it a try to flash even in this case. Start the flashing software and look what will happen.
You said, that you have successfully flashed until now, which means that the flashing tool supports you device. If you can't flash now anymore, you might also not make a backup, which would be important, because the only things you could try now, is to find the stock firmware and flashing it.
If you haven't installed any important data on your system after flashing LineageOS or if you already made backups of your applications in a cloud or another drive you need not to care. It is possible that you will need to do a hard reset before. You can find on hardreset.info, in the section "All devices", how to do it or ask the SHARP support. If you fear you have still important data on your phone a backup is normally recommended.
Because flashing a ROM not only wipes your data, but removes the guarantee, the result is: Restoring the phone to a usable device by any helping team of SHARP's customer care service in you city, even if you have any service buildings, might be expensive in this case. To go around high prices you would need too look around also for other data restoring companies or specialists, if nothing works.
But at first, if you are able to do it; I would recommend to do a hard reset of your device, which should restore it to factory setting, which should make the drivers work.
Even if they don't work, ask SHARP for actualized USB-drivers. Try flashing also with and without working USB drivers, and find SHARP's stock firmware for you device first, which is a "must do", if you want to have access to the original recovery mode again. Flash this stock firmware after you have done a hard reset. After flashing the stock firmware you should be able to go to the custom recovery mode again, if not, only a specialized company or a help team of SHARP's customer service might help.
Hello,
The adb and fastboot commands wait for the device to connect.
SHARP support is not responding.
Hello, did you try "https://getsupport.sharpusa.com/Contact-Us/Product-Support"?
Because of the actual situation with the Virus, they might need longer to answer, so you need to be patient. As I see you already tried to connect your device after the use of CMD.exe. Installing the drivers with CMD and checking the Windows Hardware Manager if the Installation worked correctly is one way to do a driver install. I am sorry if this didn't work for you. If it does not, only a specailized soft- and hardware team can help, which could get expansive, but maybe not as much as buying a new device, so I hope for you Sharp will answer and give a correct Installation guide and that it will fit to solve your problem. I wish you good luck and that you don't need any other company than Sharp to help. I know that nobody is amused if all help and waiting does not help, after bricking bis device, but unfortunately I can't do more for you. I wish you success and keep your device in a safe place just for the case.
