This started when you mounted system? Or it started when you mounted system and tried to modify something?

it actually started when i mounted system. no modifying.

ok so i got the firmware from the company that sold me the tablet. is there a way to convert the img file so i can use it with phoenix card?
no software will work for me because the micro usb connector is loose and it won't even stay connected long enough for my pc to recognize it.

Hey.
Please send me a file that I could download and firmware my device Yuntab B102.

[Q] Bricked Kross GY-601 Chinese Tablet

Hi, I have a Kross GY-601 Tablet... One of the cheap chinese tablet you can pickup at factorydirect (Canada)
I seem to have bricked it when attempting to port Clockwork Mod Recovery to it. It does not show anything on screen or do anything, When I connect it to my computer.. It shows up as M6-CHIP in Device Manager as shown in my image.
The internal storage is completly gone as a result of my failed attempt to un-brick it..
It would be a great help if someone helped me fix this..
Thanks in advance..
-Henrique
PS: I'm only 13 sorry if my description of the problem is a bit bad..
Sooo,
You probably don't have proper drivers, use PDANet ones, they work even with obscure tablets.
You tried to port CWM or flash?
It's not bricked since your computer detects it
Last thing, do you have a backup recovery image or another recovery image that works so you can get it back up?
Daniel
I was dumb enough not to do any recovery image backups..
Also.. I ported cwm then flashed it with dd just poped the .img into the recovery block.. but since I didn't compile it properly when I adb reboot recovery.. It got into a boot loop.. so I tried to fix it but broke it even more... So then I tried re-writing the firmware for generic 4.1.2 chinese tablet.. but that messed it up to the point were it only shows as M6-CHIP.. i can only turn on and off.. nothing else.. no boot no screen light up nothing..
I can help you BUT....

Mediatek GT-I9190(S4 MINI ) , MTK6572 bricked!

I am sorry if this is the wrong group for this topic to discuss, I created the account for this specific problem I am having. If am wrong then please do guide me in the right direction.
So, I have a S4 mini Clone from mediatek first of all I am confused about the model. When I used the system info app it said hardware - 6572 and something else was there it said 6589_wet so what is the correct number to follow.
Now, the problem is that I rooted that device using MTKDroid and I guess I didnt chosed a right option for recovery. One day after rooting I restarted the device and it fell into bootloop then I went for recovery menu and tried to wipe partition cache and even wipe user data. It didn't work. Then, I copied the recovery backup file from my computer (which MTKDroid creates) to microSD card and tried to recover from sdcard. Even that didnt work, then I used another method which involves formatting using SPflash, even that didnt work I guess the scatter file was corrputed because SPflash sent an error message saying " the load and target are inconsistent " and the bar turned red.
Anyone with same problem got solved or anybody having any solution or even the correct rom for my device, I'd appreciate the help.
Kingtopkt072 ROM needed
Hi
Thanks for the great job done on your website.
My KingtopKt072 MT6572 is bricked, and I’ve been unsuccesfully looking for it all over Internet. Can someone please save my phone by sending me a link to download and recover my device? It’s got 512 RAM and it’s dual sim.
Thank you.

[Q] Aml8726-mxs stuck on loading screen

Hi,
i have Dmtech tablet 1032dc. I have not tried to flash, upgrade or anything, it just wont work anymore. Last time it worked was everything ok, was shutted down properly and placed in a box.
Now it is stuck on load screen, i have tried factory reset, sometimes it freeze on formatting data, other times it finishes wiping data. But after restart boot logo hangs as before. I have tried to connect to pc with a usb cable but it wont show any devices in device manager (only if is turned on and stuck in loading animation it shows 2 removable devices as partitions, who cant be accessed). Tied Win xp and win 8.1.
CPU: aml8726-mxs 1,5 Ghz
Android 4.1
Recovery system is original
What steps should i take next in order to make it working again?
All i can think of is to flash original firmware with sd card, but i cant find any roms of this device. Pls help.

Bricked MTCD MX unit after upgrade rom

Hi,
My device,
Mtcd Mx
A-Media

Lollipop 5.1.1
i upgrade my Hu from 1.3 @hal9k to hal9k’s 7.1.2 nougat, everything went fine. Bootup successfuly. While looking settngs page “power off” warning came and after that restart it self, then stuck on nougat logo. Nothings happening just stuck. After i manage a sdcard with sd firmwaretool to downgrade 5.1.1 with stock 5.1.1 dupdate file. Hu stuck on lollipop boot logo no matter what i do.
Things that i tried
With @hal9k 7.1.2 bootable sdcard i can get into Nougat recovery menu, tried clean wipe cash, factory reset options and finally update again, there is no solution still stuck nougat logo.
With stock rom(5.1.1) bootable sdcard i cant get into lollipop recovery menu. Stuck on lollipop boot logo. Tried eject the sdcard as soon as possible when lollipop appears many time, doesnt work.
i never update dmcu, it is same as it was.
İ thing it is bricked, please ineed some advice, i m very sorry for beeing such despered
Edit: i apply this method to flash som with;
1- stock dupdate.img. Flshing succesful but stuck on boot again.
2- flash with sdupdate file of stock dupdate.img. Flashing succesfull but stuck on boot again.

Would demanding it motivate others to help?
What have you tried and from reading the forums, identified what the options might be?

i dont understand why it always gets in recovery mode with the sdcard which already bricked the unit.
understandings from readings
it doesnt get into recovery mode because it stucks or something went wrong on previous update.
To get in recovery i remove som from board, prepare a cable with 10k and 20k resistors. measure 3.2v from cable. And attach the usb cable pins to som’s related pins. Pc recognise the som, run the rk tool app, load stock 5.1.1 rom. And click restore button, succeed the restore succesfully. Plug the som back to board, push the reset button. it stuck on boot lollipop logo again. İ i tried to restore both dupdate.img and sdupdate.img by one by. Doesnt work.
The only thing that work is the hal9k’s nougat 7.1.2 rom’s sdupdate.img. İt takes recovery menu, i can wipe data, wipe cash , update mcu and update firmware. (Update firmware option only updates nupdate 7.1.2 version which is stuck on boot logo again)
i will flash mcu tomorrow by stlink method. i think mcu is fine. it wont work again.
İ create sdcards with Rockchip Create Upgrade Disk Tool v1.46 (SDBOOT 2.12)
update,
remove som, take it to maskrom mode.
with tool androidtool 2.3
eraseflash
lowerformat
upgrade firmware.
it doesnt work still.
i guess i need fully erase nand partitions and make it as virgin . but how?
installed virtual machine and ubuntu to fix by rkflashkit but, it cant recognise usb
