Hello, i am new here and i came in here for help.
It all started when i blindly flashed twrp v2.6.0.0 on my tablet, and now i regret that i have done that.
The problem is that it is stuck in a bootloader boot loop and the screen does not work at all when i am at the menu. The os is gone and i can't even go into download mode because the tablet does not have physical volume buttons.
The tablet is an estar mid 7818 mini (rebranded onda v818 mini).
Is there anything i can do? This is my last resort since i am tired of trying to find a solution to this rare problem.
edit:
The os is not gone, as it seems that the thing still has the default battery charging screen while being off, but it don't know anymore. I am no stranger to rooting and flashing, but that was mainly done on Samsung phones, which have much better support than some random chinese tablets.
I still need help, though :^(
Cheers if you read my mess.
edit v2:
I actually fixed it! So this is what i did:
1. found a thread on a different forumsuggesting that i should use iroot to download the drivers (because the device was not recognised by any software);
2. rommaster was installed with me not even knowing;
3. I pressed some buttons and the tablet rebooted to android (the ui was in chinese)'
And with my blind luck - i somehow fixed it.
Hopefully i will not end up in this mess again.
Cheers.

Hi Guys! I usually lurk around here, but now I really need some help.
Basically I have a Rebranded Chinese Tablet called "Tabulet Mech" and it's a redesign of a M701 tablet.
With a bit confidence of rom flashing, I tried flash a rom from a forum which talks about this type of tablet. With careful action I tried flash the rom using FWDN, and miserably failed T.T
while flashing on FWDN I used "Low format whole memory before download", so I guess the FWDN is formatting the whole tablet.
I dunno if I did something bad while flashing it, but since I didn't see any Recovery Mode available for the tablet, I can't exactly recover my tablet at all.
And now, I don't know if my tablet is already turned off or not, since the tablet is still heated up, and when I plug my USB on it, my PC still detect it (even my Moborobo), but since there's nothing on the screen, well you know I can't figure what's happening.
So my question is, is there any way I can install any rom to just make the tablet back working again?
Hello guys! I have a HUGE problem with my Q88 Allwinner A13 tablet.
I installed an application on my tablet called Z4root, and I wanted to root my device. Two options came up and it said:
Permanent Root
Temporary Root
I clicked Permanent Root because what's temp root anyway?! Big mistake.
So, once it so called 'rooted' my device, it closed itself. I assume it was done. The app told me it would reboot but it didn't. So I turned it off and back on again.
Apon turning it on, I realised booting took a rather long time, but it got to it eventually! But here is when things started to go wrong. There was no Superuser app/folder. It had completely reinstalled a new os (I THINK) onto my device. But this O.S (I THINK) is buggy as hell. It FACTORY RESETS every time I turn it on, can't install any apps! As far as to my knowledge, it has NOT rooted either. When I go onto settings to check on my INTERNAL STORAGE, it says 0.00B on it, when the tablet came with 4GB?!?! So, thats messed up.
Then I thought to myself, FACTORY RESET! So, I rebooted into Recovery Mode from the Settings menu. I cannot get into it any other way as far as to my knowledge. As it booted up into Recovery Mode, it came up with a picture of an android DEAD with an red ! mark. Type down ON Google Images "android boot red triangle exclamation mark" It's that. I have waited FOR AGES for the options to pop up, but nothing is there. Only the picture. So, I can't do anything about that.
As I reboot, it is factory resetted again.
Also, plugging the tablet into my pc dosen't help I think because the Android driver "Did not install correctly". So I message the person I bought it from to provide me with the driver for the Q88 Allwinner A13 tablet. Got no reply.
What do I do? I don't care about my files, I just want a working tablet. Please help and plus, I don't know any Android techy language so please comment clearly so I can understand what to do to fix my Q88 Allwinner A13 Tablet. Thanks.
P.S I can boot into recovery using the BUTTONS. I have a POWER button and VOLUME ROCKER.
same problem
Hi,
I have the exact same problem with my allwinner 13 and the reason is Z4root.
The problem is that half of the memory is locked (1.96Gb) and it prevends installing apps. With ADB you can install things on an SD card but nothing works good and rebooting will give you factory settings.
The supplier will send me an SD card so I can flash the device.
If I have it I will come back to you (if it works).
How do I get in recovery mode with the buttons?

Hello,
I own a fabric new Tablet from Lenovo [TAB 2 A7-F10] since few days, and I've problem which I fight already all my day, and from hour to hour it's even worse.
Earlier my tablet had Android 4.4.2 and stock firmware, which i successfully rooted, and to the certain moment much later tablet had worked fine. Today in the morning I wanted to update it by Lenovo smart update, unfortunately it ended with failure so I've just rebooted it, yet tablet still worked fine.
Background at applications changed to blue, in the end I couldn't get rid of it, so I turned off rooter and rebooted tablet into recovery mode. There I selected factory mode option and the horror started.
After certain time, I found out that the loop of not going further than to the recovery mode, is caused with ROM's problem. (Soft-brick)
Here on XDA I've read how to flash tablet with new stock ROM for my Lenovo tablet. I couldn't find a ROM's version for KitKat so I used Lolipop version instead. After the flashing has been ended successfully, I wanted to reboot my tablet, but that didn't worked.
It wont turn on, nor it won't vibrate or show reaction with computer. Tried to enter recovery but still nothing.
I feel shattered and really upset because of it, I'm looking forward for any help and I hope you could help me with this..
Thanks,
DeidVesp.
Hi guys, sorry if I posted this at the wrong place.
I have a Lenovo s860 and it went into a bootloop. It was stock and all so I thought that I can have my files recovered if I just bring it to a service center so they can get the files first before wiping it or maybe even fixing the bootloop without wiping the device. Well, the thing is, the guy at the service center screwed up and now, when I try to turn it on, I still see the boot screen (Lenovo, powered by Android) but the next screen is like an television with bad signal.
I'm familiar with rooting and flashing ROMs, I've tried it on my Galaxy S2 (yeah I know, it was way back), but I think things are still more or less the same: I need to be able to boot into recovery mode in order to root the device. However, when I tried the Power Button + Volume Up, or any combinations of the Power Button and the Volume Buttons, it just goes straight to the dead screen, I get no response whatsoever.
I also tried to check if adb can detect it, however, it didn't seem to be able to do so. I'm using a MacBook Pro so I know I don't have to install any drivers, I also code Android Apps so I have a background on this.
I think my only option would be to flash the ROM on this dead device but I don't know how to do that. I've also seen some posts that suggest doing some things (I forgot the specifics) while the battery is drained, so what I'm doing for the mean time is to leave the phone open and let it drain which might take ~2 days.
Does anyone know how to flash a ROM on a bricked device? Thanks for any leads.
So, for Christmas my daughter's mom got her an A33 Q88H QuadCore Softwinner tablet, and we discovered the OS it came with had some very strange issues related to a lack of compatibility with Google Play, so I tried to get around that with software, but I needed to be rooted. However, I had bizarre difficulties with SuperSU, unlocking the bootloader, rooting, and even more difficulties trying to flash a custom recovery that I could use to ROOT-- the obscure china tablet had no TWRP or CWM support. I finally tried a very convoluted method of flashing what appeared to be a ROM for the A33 Allwinner tablet, which hadTWRP already installed, so I could use TWRP to root it, and then finally fix the software issues.
However, the process didn't work, and when I rebooted the phone, I found it stuck on a black screen with a tiny android symbol, and that's how it's been since. Holding volume and power button only reboots it to the same screen -- no bootloader or anything, so I can't find any way to try to flash a factory ROM to get it back to regular settings. When I plug it into my computer, it makes the input noise, and shows up in Device Manager as "Android Device" with "Android ADB Interface" drivers successfully installed, but ADB doesn't recognize it as a device, and I can't get it into any sort of download mode -- it isn't recognized in My Computer as a hard drive. So, I can't find a way to interface with the tablet to reflash a stock ROM. :frown:
It's her Christmas present, so I don't want to admit that I've broken it; I've been trying to solve it all night for 12 hours straight, but I just can't find anything that works! Is there any way you guys can help me? :crying:
I tried to attach some pics but the uploader isnt working.
