Hi guys,
I just bought two brandnew Cube U27GT S (MTK 8127) tablets and tried to install a custom rom. Unfortunately the tab hard bricked while trying to flash it with SPFT. Now I can´t turn on the tab anymore - all black. I even can´t open the recovery mode and Win 7 doesn´t found the tab anymore, it shows unknown device in the device manager!?
Meanwhile I deinstalled all MTK drivers with usbdeview and installed them again with the help of the second tab. But it has no effect of the damaged one it´s still an unkown device.
Maybe anyone has an idea how to unbrick it? Would be great to get any help! :crying:
No hope anymore?
I have the same problem can only get into recovery, factory reset does seem to do anything still hangs on boot, looks like I need to update via sdcard?
Apparently sometimes it's not the best idea to use the flashing software that the manufacturer of your phone released.
I have a Wiko Lenny(technically a MediaTek MT6572) that has(or had - now it's dead) the habit of simply rebooting into a bootloop every few months. Fixing that was simple; just start SP Flash Tool, format everything then flash the stock ROM back. Last time I did that was around 4 months ago, and since then I have upgraded to Windows 10, and as such, lost the tools I had installed.
Yesterday it went into a bootloop again. I didn't remember exactly what tools I used, so I assumed they were the tools that Wiko supplied a while back with the V10 ROM. Well, they weren't. I still thought I'd give them a try. I mean, it's from the manufacturer's site, so they must work even better that the ones I was using.
I was wrong. The tool flashed the ROM "successfully", but the only thing it actually succeeded to do is corrupt the preloader. For those who don't know, corrupting the preloader basically means the phone won't even power on(not boot, actually power on), won't charge, and the PC won't detect anything if you connect the phone. Practically, it's the hardest brick a phone can get.
The fastest way to fix that is by either using a JTAG connection to flash everything manually, or by entering something called the Mediatek META mode(don't quote me on this one, though - I never heard of it before). JTAG - well I don't have the tools or expertise necessary to do that(although I'd love to learn how to do it - if anyone can point me to a well-written guide or two about that, please do!), and I simply can't get the phone to enter the META mode.
Is JTAG the only way to do it? Is META mode just a myth? Is there a way to save my phone, or should I just say "RIP" and buy a new one(I have the money for a Samsung Galaxy A3, the new one, but I was planning to buy a new computer with that money - is it worth it?)?
TL;DR (It's not that long but anyway...):
I have a Wiko Lenny(Mediatek MT6572) with a corrupted preloader after I flashed it with Wiko's tool. Can I repair it or should I just buy a new phone?

Come on people, let's fix this little guy.
EDIT: Please, just tell me what your ideas are... A tip, a crazy idea, some details about MTK devices that could help, anything is appreciated.
Please...
Looks like I'm getting the 10 posts just by begging people to say something... :crying:
I have an MTK phone and its always going wrong and not booting/turning on because I mess with it and break it
I'm sure I flash the backup I made in mtktools with spflash, and plug the phone in with no battery attached, I also have to use windows 7 on a dual boot as windows 10 never played ball properly. You also need the mtk VCOM driver installed, not just adb and normal drivers. If you have all these, and have tried them, then that is the end of my knowledge sadly. Only other thing is going to needrom and seeing if they have a full rom/backup with partition tables/preloader etc.
Also, had to try a few versions of sptools as certain versions didnt work, forget which one I have and which didnt work. And also had to use a samsung USB lead as the stock one didnt work, or the other way round. I just remember it was a ball-ache but did eventually work. Am not on that pc so cant be more helpful, sorry....

Thanks for replying. I'm not sure if I have the VCOM drivers, but I'll check. Luckily I also have a Win7 PC besides this one, so I'll try it there too.

Repair your own device
Soft Brick: Soft brick is the state of android device which occur due to some software problems like boot loops or phone freezing at some point during boot. This only occurs if some software problem occurred in the device mainly during OS upgrade or ROM flashing. If your device is in such state then you are luck there are 99% chances that you can recover your beloved device without needing any professional help or spending hundred of dollars.
Hard Brick Hard brick is the state of android device that occurs when your device won’t boot at all i.e. no boot loop,no recovery and also not charging. This occurs due to trying to flashed firmwere not made for your device or flashed incorrectly. This is more difficult to resolve and often require professional help
in MTK Android there is many Partitions in your phone. like Preloader, Recovery, Bootimg etc….. if somehow Preloader get Corrupted then you phone will not able to DETECT WITH PC !!! in other words you will have phone with BOOT DEAD.
How Preloader get corrupted ?
There could be few reasons but main reason could be that someone or you Flash your complete phone (include Preloader) with wrong files or with wrong ver. Also there could be reason someone Delete Preloader or you Deleted.
How could i know my phone have preloader dead ?
Preloader can be dead if some one Flash it wrong and after flash your mobile will not detect with pc any more. for confirm
1.sp flash tools does not detect your phone anymore and also the computer does not as there is a pop sound when usb is connected to device
2.open device manager
take battery out from phone
insert usb
insert battery
and check is computer detecting any device
If it’s not detect then you have phone which Preloader is dead AKA Boot Dead
How can i repair it ?
requirement
1.screwdriver (by which you can open the screw from handset)
2.bricked device
3.a usb cable
4.a copper wire( for sold test points)
5.a pc with sp flash tool,mtk drivers and stock firmwere for your mobile
now you have to disassemble your phone and take pcb out. check there should be some Golden points. check these points there should be written on them Rx,Tx,GND,Vcc,Vcharge etc… check there should be written “COLO” or “KOLO” or“KCOLO” you have to Sold that point with GND After Sold Attach usb now your phone will detect with USB !! and now ready to Flash.
In some phones “COLO” or “KOLO” or “KCOLO” not written for those type of phones you have to test all points one by one Short Golden point with GND and attach usb cable which point short with gnd can able to detect your phone by pc isForce Preloader Mode Test Point !! Keep in mind Don’t Short Vcc,Vcharge or any other pin which have 4.x Volts also i had tested “Colo” or “Kolo” or “KCOLO” don’t have any kind of volts.

HI sir how can I contact you
Hi I also have the same problem - when I flashed the stock rom of my LG K7 X-210 (MT6580__lge__LG-X210__m13g__5.1__ALPS.L1.MP6.V2.19_ARIMA6580.WE.L_P42) with the SP Flash tool when I was in a bootloop, I accidentally forgot to uncheck the preloader option. I flashed it to my phone and from that point onwards it didn't want to start up any more, nor would it react if I tried charging it. So conclusion: the preloader is corrupt...
However, I read online that MTK devices (mine is MT6580) have a 'meta' mode which allows your device to still connect to SP Flash tool even if it is hardbricked (in my case by pressing the volume up button, and then simultaneously plugging it in the computer). It is then recognized as MTK Com port something in device manager.
Luckily I have the same phone (but it's not mine) and I was wondering if it was possible to make a full rom dump from that device and restore it on mine? (a method that is safe for the other device as well)
i have a proble on my new phone since i flash preloader my touch is not working anymore, any solutions ?

I need to repair preloader of My Nokia G20.
hello this is very simple.
i solved this problem.
i wrte english very small.
flash atarken yanlış attığın preloader dosyası ile başlat.cihazı bilgisayara bağla.format bittikten hemen sonra doğru preloader dosyasını klasörün içine yapıştır.ama çok hızlı olmalısın.yani uyumsuz preloader dosyası ile cihaza yükleme yaparken tam format esnasında uyumlu olan preloader dosyasını hızlıca yapıştır.

Hello, is it too late to write?
First of all, sorry for my bad english. My problem started when i deleted accidentally one partition of the tablet, trying to make an working twrp for it. Now I have no adb commands, no recovery, no fastboot,no logo,no display light. Nothing works. Just an expensive brick. PC only see something like "diagnosis 900E, instead of USB QDLoader 9008,so QFIL can do nothing to fix.I have changed driver,now can be seen QDLoader but QFIL gave me errors. I just bought another tablet, same model, for my son. I will try to pull out system, recovery, boot etc. But after that...? Any chance to make an bootable microSD card with those files? Any advice please?

Follow guide of Androidbrick.com.
The tool posted on these site is actually a ZTE tool studio tool by name of Androidbrick tool.
Just Google and download it from torforum.org

These tool unbrick your android when no fastboot, no recovery, not booting by anyways. Just detects in 9008 port. I am sure it's better than Qfil.
That`s the problem with port detection
How does this happened ?
Hello Costi979,
Sorry for your tablet, I hope you will find a solution
I wanted to know if this happened when trying to install TWRP on this tab2 10-30 tablet, under Android 6.0.1, like explained in this thread : http://forum.xda-developers.com/android/development/recovery-lenovo-tab-a10-30f-l-twrp-3-0-t3442588 ? Can you confirm that it does work or not ?
Thanks for your explanations,
I hope you will success to recover your tablet,
