Hi, i need some help. I have Lenovo Ideatab A1000-F (MKT6577) with installed TWRP recovery, but i have one problem. If i connect turned off tablet on PC, the preloader (PreLoader USB VCOM Port) driver starts, but then after few seconds disconnects and tablet starts charging trough USB ... I want to flash something (AllegroROM) to it but when i have only 2-4 seconds its kinda bad ... I have installed all kind of drivers and trying it againg and again, but nothing works. (I think the problem is that i cant remove battery to avoid charging.. or? ) Please help. Thanks.
Btw sorry for my english and for 2 posts.
Anyone?

Hello
Just a few days ago, my HTC Pico (Explorer) stopped connecting to my PC.
It still keeps on charging but the connection-selector screen stopped showing up every time I connect it to the PC.
The last time it worked was before I connected the cable in bootloader mode (I was trying to root my phone).
I selected fastboot, pressed the power button and then connected the usb to PC when suddenly the PC started to install a "Android 1.0" driver.
It failed, and I got a "Device malfunctioned" message.
I powered down my phone, booted in normal mode, and connected it again to the PC, but my PC didn't recognize my phone.
I've tried all the basic troubleshooting tips like pulling out the battery, checking and double-checking the physical connections.
I even re-installed my USB port drivers of my computer. But the problem is still not fixed.
Everything was working perfectly until I connected the phone in bootloader mode. Did the malfunction had something to do with that?
My USB cable is working perfectly. The phone keeps on charging like a normal charger.
Has this happened to anyone else? A little advice would be greatly appreciated.
Regards

Thanks a lot.
Though I didn't need to install the whole platform....just installed the HTC Drivers from /Data.
Successfully rooted my phone. Thanks once again.
I tried to downgrade the kitkat version because I couldn't update my apps, using a flash tool.
It then shut down and now does not turn on at all. When I plug into the computer the USB gets into a cycle/loop of connect and disconnect. Please help me if you have the time.

no. But I think it goes on '''META MODE'" ONLY on the computer for a few seconds.
Thanks for commenting.
Check device manager in your pc when you connect your phone, is it showing MTK 65xx preloader

I used this one.
forums (dot) lenovo (dot) com/t5/A-and-P-Series/Lenovo-A536-stuck-during-firmware-upgrade/td-p/1744571[/url]
I downloaded the latest firmware from
"THIS is the latest original ROW firmware (PC Flash Tool installation)"
This whole guide was fine, it worked for me.
But the problem was when I tried to downgrade the firmware to an older version.
I tried to replace the lastest official firmware with this one ROM Android 4.4.2 (older official needrom(dot)com/download/lenovo-a536/
sorry can't link websites yet

Thank you so much for staying with me to solve this problem. The phone is fixed.
I followed the
"
For MT6575/ 77
With the battery out, hold the volume up, don't let go & plug in the USB cable will activate META mode for few seconds...Typically, you need to click Download at SP Flash Tool before entering META mode or it will auto disconnected...
"
except I downloaded the lenovo a536 stock rom.
the only thing I did different was that I plugged in (META MODE) and THEN pressed download or else the usb would never be detected (they both show different COM numerals.)
After that I firmly held the whole usb into the phone during the whole flashing, or else it might get automatically disconnected again.
Then I updated/upgraded to the latest firmware, And it is all optimal. :good:
THANKS AGAIN !!!

What do u mean by "it is constantly going off while installing"
Does it boot in recovery mode? Please be as specific as you can while posting questions.

I don't think you need to connect phone during installing drivers and phone will stay connected after properly installing DA Vcom drivers

Hello.
I have a problem with my lenovo tablet
During flashing a older stock rom in, I selected incorrect rom and now the device doesn't boot.
Doesn't react to holding any combination of volume +/- and power.
Doesn't react to power button at all. If I plug it in to a charger, it doesn't show the charging animation.
SPFlashTool is unable to do anything after I pick the device, it sees it but is unable to flash it in. (I will attach logs after I get home)
Windows still detects a MT65xx Preloader after I plug it into a USB port. (I have removed the MTEK vcom USB driver since the flashing attempt)
Is the situation still salvageable? Can I somehow still give life back to my bricked device?
Thanks in advance.
Well, almost a year later I've bumped into the exact same issue.
Anyone knows how to solve this?
Damn...
----EDIT----
I've managed to sove this. Had to open the tablet and remove the cable that connects the battery. Once reconnected, the tablet was able to be powered on.

Bricked Lenovo Tab 2 A7 10F
I was trying to flash TWRP and get my Lenovo Tab 2 A7 10F to root but during the process i don't know which scatter file i chose since it the scatter files were more than 1.
So i tried one by one all of the three scatter files and tried to flash but I don't know which scatter file i chose. So i removed the USB from my tab since the bar at the bottom wasn't progressing and now the tab won't turn on.
KINDLY SUGGEST ?? :'( :'( Otherwise my dad go angry on me. PLEASE !!! PLEASE !!! PLEASE !!! PLEASE !!! SOMEONE SAVE ME _/\_

I just opened the back cover and disconnected the battery cable. I didn't remove the battery.
Anyway, you can search youtube for videos that shows you how to open the back cover.
Cheers!
Thanks for the help!!! had the same issue

Hey, i was in the same problem some weeks ago.
I finally figured it out after spending 2 nights continuously, so here is what you need to do.
1. Carefully open the back cover of your tablet and find the square connector which connects the battery and disconnect it.
2. Now download the stock Kitkat rom for the tablet from xda.
3. Install vcom drivers for mediatek 65xx.
4. While the connector is removed plug the cable to the computer or laptop.
5.Then connect the mini usb to your charging port (Again the connector should not be attached to motherboard).
6. Load scatter file in sp flash tool uncheck preloader, MBR and SEC_RO.
7.Then hit the start button and wait for it!
8. Now remove the cable, attach the battery connector to motherboard. AND BOOT!!!:good::good::victory:
If this help you please give a thanks.

Hiya
My computer doesn't detect my phone when it's in bootloader/fastboot mode. I can tell because the charging light on my phone is not shining and no fastboot commands work.
I've been on lots of forums and posts. I tried installing drivers. Didn't work. Tried a different cable. Nothing happened.
Please help I need to flash a zip to stop cell standby ripping my battery + root my device later on.
It's an Alcatel pixi 4(5) 5010x
A fast response would be lovely.
Thanks xda

Forgive me for trying ....
