[Q] Bootloop (?) - Android Q&A, Help & Troubleshooting

Hi,
I've recently bought a second-hand polaroid mid1047pme01.112 tablet and the previous owner has made a big mess with its software. I'm trying to bring it back to life but I can't find a way.
Actually it can power up and show an image with Polaroid written on it and it won't do anything else. I can't access the recovery mode so I don't know what I can do to install a working CWM (I think I already found a working copy of it, but I don't know how to install).
If the tablet is connected to a PC it doesn't react (the PC doesn't show nothing, even the driver installation procedure).
May you know which are the steps I should follow?

[Q] Unbricking a Chinese Tablet

I have a Trio Stealth Pro 9.7" Tablet by Mach Speed that came with ICS. It wasn't able to run much of anything so I tried to upgrade and needless to say it didn't work.
First, I installed CWM. I did this because the device appeared to have no recovery mode I could find. That seemed to work at first but then I discovered I could ONLY boot into CWM.
SO, I tried to use Live Suit to flash an img of 4.1.1 (I know, a stock file from the manufacturer would have been best but please don't tell me to download one unless you have a working link - I've tried without success).
When that failed, I figured I'd try something else except now I only get a blank screen - not even an initial logo. The only way I can tell if the thing is on or off is by plugging it into my computer, pressing the power button and listening for a usb connect or disconnect noise. (My computer currently recognizes it as USB Device(VID_1f3a_PID_efe8) although it originally recognized it as a Trio something or other).
Any help would be fantastic. Thanks in advance.

Please read carefully. You must check first whether you have 9.7 or 9.7C before flashing!!!!
Check this if your tab has the Allwinner a10 chip. This worked great for my A10.

I appreciate the reply but I don't know how to flash a zip without the use of my tablet screen. I can use Live Suit but that only seems to flash .img files.
Also, I'm not sure how to tell if I have the 9.7 or 9.7c

Comprehensive guide on unbricking the ASUS transformer pad 103c (TF103C)

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 ?

Hello,

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 ?

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

Hi, I see that the thread is old, but I need to fix my old pad. I can do all the steps, but the problem is that I can not find a clean system I can install. I will really appreciate if someone could give me a link to one.
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?

Tablet stuck on EFI Shell. USB ports disabled.

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

iRulu eXpro X1, model X10 - not booting

Hi all,
Hoping someone might have some knowledge on this Chinese cheap build tablet.
Its an iRulu eXpro X1, model X10. Inside is the Allwinner A83T with 16Gb Rom and 1 Gb RAM.
This was previously with my daughter but we just upgraded her to a Sumsung Tab A, so I thought I'd play with the iRulu (bad mistake lol).
The iRulu was still running kitkat so I rooted it (Kingo Root works fine in anyone else is trying), attempted to install CWM and TWRP. Both failed, every attempt through adb / fastboot gave bootloader: secure mode fail error.
So I them decided to flash the new rom from iRulu's website - using PhoenixUSB.
All was going well, the tablet went into download mode (hold Esc button, plug USB cable in and press power button 10 times in rapid succession.) and the firmware started to download. At 80% PhoneixUSB threw a boot(0) error and stopped.
After this the tablet will not start (nothing on display) nor even show the charging icon on the screen! It does however still enter the download mode so I can try other images. So far I have tried 5 different images (including darkglow10.1_android5.1.img, A83T_N102_N1021L1BC_20151123.img) however all of then error when writing to the bootloader. I have also tried PhoenixCard to write an image in Startup mode - this gave nothing Live Suite makes no difference either, using the images I have.
Unfortunately the serial number has worn off the device so I cant be sure of the exact firmware from iRulu website to install. (I've mailed them for what its worth).
I have opened the device and the pcb is marked INET-N102-REV01 and Zeng-gc2014-12-22. Google has some stuff on it but nothing I understood
Does anyone have any thoughts? I'm concerned that the bootloader is locked / corrupt in some fashion which is stopping the download.
thanks
update: using the x1081 firmware from iRulu and PhoneixCard I have restore functionality. The device thinks its an expro x2 plus and it doesnt recognise the SD card slot (tried multiple cards) but other than that it seems okay
Will try to figure the correct firmware thou - anyone?
thanks
Having the same issue
Hello, I am having the same problems with that tablet, got it from this girl I'm seeing. It was freezing whenever it connected to the internet, I assume was a ROM issue, i flashed an incorrect recovery on it after getting frustrated. Can you please help?

No way to update my Asus TF103C (K010)

Hi everyone!
I've one old Asus Transform TF103C aka K010.
I find out that it's possible to update to Android 5 (and I need it for some app).
Right now, my firmware it's WW2.2.33.143 but on the Asus support page, there is the WW2.2.33.144 update that it's mandatory before trying to install the update to Lollipop.
OTA doesn't find anything and either manual download works. The manuals say that after copying the file the system will recognize the update and ask me about...obviously, this doesn't happen.
Someone know an "how to" about?
Problem solved!
How did you solve it?
How did you do it? I have a perfectly good TF103c that is useless because the version of Android is too old. It probably has enough ompff in the hardware to run the latest android if it was available.
if you have TF103C you can install Windows or Linux on it i still searching for drivers ( for wifi sound and charging solution ) ..
For now if you install Windows or Linux on it and your battery die you will need manualy charge battery ..

how did you solve it?
Hello,
I have an old Asus Tablet of the transformer style (docked to a keyboard) model TF103C or K010. It came along with Android 4.4.2 installed. I rooted the device sometime ago, and can verify that is rooted by using the app “Root Check”.
It is still a nice tablet, but with such an old version of android it tends to be limited and with less features, hotfixes, etc. Long story short, I was trying to install a new rom in a little bit of a hurry, used adb to boot into recovery mode (adb reboot bootloader), and used some images and scripts that I downloaded for a similar device (not exactly mine)…Then I went ahead and used scripts – which mostly used fastboot.exe adb.exe. The problem now is that nothing has changed as far as I can see, and I am no longer able to boot in the quick boot mode (using “adb reboot bootloader”): whenever I try to reboot the K010 connected to my computer in quick boot mode it simply restarts, goes to the splash screen (“Asus in search of the incredible powered by android”) with the caveat that there is a red blinking red stripe at the bottom of the splash screen, and then it simply turns the K010 off (battery charging screen)
Is there any hope to enter into the quick boot mode and fix that mess? Thanks for any insights.
