Hi. I own a Lenovo S850. While trying to update system from the settings, it suddenly turned off and never opened. So I downloaded the Stock rom and flashed it via SP Flash tool. After opening the mobile, it was not like before. SO I downloaded stock rom from another website, connected phone with SP flash tool and formatted from there. It showed ok. Then I clicked download with Da/DL checked. But it couldn't detect the phone. I reattached the USB(It has attached battery), it showed USB connected on Device Manager but SP flash tool couldn't detect. I tried from 3 different PC's.
Duo to 1st post on XDA, they aren't giving me permission to post the link of screenshot. But if you want to see, just remove the space before .com and paste it to browser : i.imgur .com/sj8So7S.jpg
Before formatting the last time, USB VCOM only connects for 2 second, I had to click download and then I needed to attach the phone. But now it doesn't connect for only 2 seconds. It shows the whole time I connect with PC.
I uninstalled every driver with USB deview, reinstalled and updated VCOM driver. But nothing changed.
When I click and hold the power button, nothing comes up on phone, not even the backlight. Tried to enter in recovery mode, nothing shows. What should I do now?

Hi all,
I have a Star/Bluebo B6000 phone which I believe is based on the MediaTek 6589T.
I followed the procedure here: http://forum.xda-developers.com/showthread.php?t=2206421
to set up a new ROM for the phone.
I seemed to have gotten it all done properly, but the phone only stays connected for about 2 seconds. The SP Flash tool moves into the red progress bar and then just fails.
Luckily, there isn't any software damage on the phone (from the look of it).
I'm trying to put in a new ROM to actually fix a previous issue where my phone remains on but when I press the home button or the power button the screen stays blank. Think a new ROM/fresh start may solve this.
But the core issue is that I am unable to put in a new ROM because the phone doesn't remain connected long enough.
Is there a solution to this? Or is there another way to install ROMS?
Thanks.
There are several things the issue could be.
Try running SP Flash Tools as Admin.
Try a different USB cable.
Try uninstalling current drivers and using PDANet VCOM USB drivers
Try a different PC
Try MTK Flash Tool as opposed to SP Flash Tool.
Make sure the scatter is correct. Create a new scatter with MTK Droid Tools
None of them work.
I've tried 4 different cables. MTK and SP tools.
It seems as though something is wrong with my preloader. When I try to 'restore factory settings' or even try to restart in recovery mode, the phone doesn't do anything. It's almost as though these modes don't exist or are bugged/busted.
EDIT: Yes, it seems to be some kind of preloader issue. When the phone is OFF, I connect the USB (which the computer recognises) and the within 2 seconds the 'disconnect' sound comes up. Within 2 seconds after that the battery charging shows up on the phone.
I say this because when the phone is ON, I am able to transfer files onto the phone and treat the phone as a normal connection. Something within the phone's software is causing SP Tools/MTK Tools/Other drivers not connect to it. I have a feeling I may have a corrupt/broken preloader/recovery system.
Thanks for the help. Please do advise as to what I can do.
Anyone?
Really could use some help.

Hi, did you manage to get this sorted?
I bricked my phone while installing official update from system update. I tried to flash it with SP flash tool, loaded the scatter, formatted it and then clicked Download with Da Dl...
my phone was detected and started downloading but it wasn't writting the preloader, it was stuck in 0%.
So I reattached the USB cable but alas, My computer culdn't recognize it. Windows says "USB Device not recognized"
I tried 3 different computers, uninstalled every driver with USBdeview. reinstalled them. But nothing changed. Tried pressing power and volume buttons combo. Nothing happened.
What to do now?
N.B. I flashed it with same scatter & firmware before. It was ok then, but last time it bricked.
Device: Lenovo S850
MT6582
Hello all.
I have hit a problem with my Hisense c20. I rooted using kingoroot and everything seemed to work fine. SuperUser was installed and working as it should. The phone then ran flat so I plugged it in and booted but it just hung on the SMART powered by android screen. So I restarted again into recovery mode and cleared system cache. Rebooted again but same thing. So tried again but with the wipe user data option. Still just hangs there. I then decided to try flash a stock rom via needrom. I followed the instructions but cannot seem to get the phone to be visible as a com port on Windows 7 64 bit. I have tried different cables and USB ports and reinstalled drivers countless times. Please could anyone assist me on getting this phone to be seen as a com port so I can flash it with QFIL.
Kind regards
Ryan
Ok so i managed to figure this out on my own. Basically what i did was plugged phone into pc while holding volume + and power. Phone showed up as Hisense in device manager, along with ADB device and USB composite device. I then right clicked on Hisense and uninstalled driver. Then i downloaded QCDLoader drivers and manually installed the driver via Have disk option and made sure to select the 9006 port driver package from the qcser.inf driver package. Once that was installed the phone was detected as a COM port. I then went into eMMC software download program in QPST and set the phone to download mode. Then back to device manager and saw QHUSB unidentified device. Right clicked that and went through same procedure as the 9006 driver except selecting the QCDLoader option instead of 9006 package. Phone then allowed me to flash Stock rom and was unbricked after a cache clear and system wipe. Took 3 days to figure it out but it worked. If anyone reading this is struggling with the same problem, let me know and i can go into more depth to try help. Really late and about to head off to bed.
Kind regards

Hi Ruan. You haven't found a custom recovery?
Hi, i bought power 2, phone not open and noting happen when press power or vol+ - together + power, or ....try everything
Bricked when try flash twrp recovery. later i try flash rom again, my computer see phone when phone is closed. can not open already. But now my computer not see the phone:A request for the USB device descriptor failed.
What can i do, and sorry for my english
This phone can't be bricked (mostly). You can easily restore the stock firmware, just download stock rom from official site, extract it. And use sp flash tool not the one that comes with the official rom. Open sp flash tool.
Load scatter file from official rom, you can leave the DA file for all mtk phones that comes with stock rom or use the one in sp flash tool (just leave it as it is) in the user interface of sp flash tool.
Make sure it says "download only" from the drop box. Click download then connect the phone to your computer. Flashing will start and should take about 1 minute and 30 seconds to finish.
If flashing doesn't start. Make sure you have vcom drivers installed. (Also for flashing to start, phone must be turned off obviously, but since you have semi brick, you don't have to worry about that).

Go to developer mode menu (if you don't have it, tap on "build number" in "about phone" from settings, seven times and it will be activated). Then change how your USB acts when connected with computer.
If you can't, just use ES File explorer to send files between your computer and phone in FTP or SMB mode over WiFi.
Have the same problam.
The pc recognize the vcom device but only for 2-3 secconds and then disaper, then i get an error with sp flashtool.
Phone isnt tured on. At all.
I also have the same problem.
Is anyone has success with unbricking Power II in such case?

I do not know if it is late. I had the same problem with another phone. I was solved as follows:
1. Unplug the usb cable from the computer
2. Power off the phone
3. Press download on sp flash tool
4. Holding vol+ and power, plug the usb cable on the computer.
Hi,
can anyone provide me with nvram /nvdata backup please of Ulephone power 2?
I have probably correct IMEI, valid MAC fo Wifi/BT ...
It looks like my serial number changed to 123456789ABCDEF and I have no idea how to change it to original because MAUI (?) stucked on get kernel
I can find original box with correct serial and IMEis on stick
The only one problem with mobile is I am not able connect to mobile network - registration SIM to mobile network always fail.
and at MTK engineer I have only Bluetooth, FM Receiver, Wifi, Wifi CTIA, Wifi Display
I have nothing like Radio, CDS etc ...
OEM unlocked, TWRP, rooted
Some information probably lost when flashing
And of course another problem :
except GPS and proximity, all sensors does not work - G sensor, acceleration, magnetic sensor, compass . Probably configuration data is located at nvdata
i tried flash 5MB file nvdata.bin from different MTK 675x device, but nothings change
I tried flash 33 MB nvdata.img from same MTK 675x device, but I lost IMEI and nothing solved
This is why I need 33 MB NVDATA.IMG from another functional Ulephone power 2
I can change IMEI at MTK then ...
I had to flash , because phone was unusable - it stucked mostly on obtaining IP address wifi
after a while, phone disconnected from wifi and cant find any wifi or if find, then cant connect because of some security issue , after restart all was OK ...
Thanks
Now, i have seen countless cases of people being not able to flash their MMX A311, as for me I was having the same problem too, turns out that the driver is the main problem.
I was trying out YGDP but i was stuck at "Enabling Download Mode"
and while trying out SP tools i was getting an error "s_brom_cmd_jump_da_fail (0x7f3) " .
Then again, I tried many things, and got my phone working in 10 minutes. :good:
So if u too are stuck, then try my method.
It is highly recommended you do this in Windows 7.
I did everything while my phone was switched off but battery was inserted.
Disconnect your PC from internet just to be double careful about the flashing.
First getting the proper driver:
Now, before installing the driver, make sure that you dont have any other driver installed rather than the one which i will provide, if you think you might have installed some other driver then try removing it by "usdreview" (but it didn't work for me though that's why PLEASE TRY THIS ON ANOTHER COMPUTER OR LAPTOP, MAYBE IF YOU HAVE ANOTHER LAPTOP OR COMPUTER OR MAYBE TRY IT ON YOUR FRIEND'S SYSTEM. THIS SOLVED THE "ENABLING DOWNLOAD MODE" PROBLEM FOR ME)
Download this driver, I did with this one:
Remove the (dot) and put " . " in the link. .
www(dot)mediafire(dot)com/file/8v32j8h5doflzi0/Mediatek+MT65xx+Preloader+Driver(dot)rar
Click to expand...
Click to collapse
Extract it and remember where the folder has been extracted to, as it will be needed to install the driver.
Installing the driver:
Open up Device Manager.
right click on My Computer > Manage > on the side pane click on "Device Manager"
Keep it open.
Now first CHOOSE A SINGLE USB PORT WHICH WILL BE USED BY YOU THROUGHOUT THIS WHOLE PROCESS. DON'T CHANGE IT!
Now use your usb data cable and insert it into your chosen USB port and then to your phone.
As you will insert it you will see a device popup in 'Other Devices' or some other tab named as "MTK65xx Preloader" or something similar like that.
NOW BE QUICK IT DISAPPEARS IN 3-4 SECONDS !!
Quickly right click on mtk65xx preloader and select "Update Driver Software"
Now as in the new window opened up, select " Browse my own computer to install the driver"
Browse to the DOWNLOADED DRIVER'S folder, select the folder "Win7" for Windows 7 and Above.
Now the driver will be installed.
Now after being installed, take out your phone from the usb cable, dont remove the usb cable from the computer because you make mistake while again inserting it back into to a different port.
Getting the stock rom and YGDP tool:
Now get the stock rom for A311 and YGDP tool from any verified site.
I downloaded mine from :
Remove the (dot) and put " . " in the link.
www(dot)needrom(dot)com/download/micromax-a311
Click to expand...
Click to collapse
Download from this site needs user to be logged in, it barely took 2 mins for me to register and download it.
If you have any other site you trust then go on and download it from there, but I recommmend you to follow my steps and sites as I did everything and succeeded.
Download the ROM and also the YGDP tool.
Extract the downloaded file to some specific folder as this is the ROM and the tool required.
Installing and Using the YGDP tool:
I have seen people recommending latest YGDP tool but on the contrary I recommend the downloaded old version from the previous step, it worked for me like a charm!!
Install the YGDP tool from the extracted folder.
After installation, YGDP desktop icon will appear, open it.
put the password as: 369
Now, on the top pane, press the button "Config"
In the window opened, on the side pane, carefully select "8297W" for A311
And after selecting that, on the left side section,
in the " Please select CPB file : " , click on the button beside it and browse for your extracted folder of ROM and select it !
now it click " Apply " button .
It will take 1-2 minutes, and after this you will be brought back to the main window!
Now click on " Start "
And wait till in the bottom message log it says " ENABLING DOWNLOAD MODE" , now follow the next step !!
Flashing your phone:
As YGDP stays in enabling download mode, now insert your phone back to the usb cable which was left out in the computer.
Now, if you did everything correctly, YOUR PHONE WILL BE DETECTED and YGDP will start flashing by itself, wait till it says 100% with a green bar.
Remove your phone from the USB cable and then click "STOP" in the main window of the YGDP tool.
Power on your phone.
Your phone will be successfully be flashed and alive !!! :fingers-crossed:
FROM NOW ON, ALWAYS MAKE A BACKUP . :silly:
Feel free to ask questions. :laugh:
If u have suggestions, I'm open for it!! :laugh:
While I am connecting to the computer it does not recognise it and continuously connecting and disconnecting the USB drive and I have tried different ways like why GDP tool and SP Flash tool when I tried with why GDP tool it struck at the entering download mode and when I tried with SP Flash tool it recognise the device but ends with an error message finally the problem is my computer is not detecting the device properly and I have install the drivers manually also but of no use now I am not able to go for go to the recovery mode my phones is continuously rebooting please help me thanks in advance
as you said i have done all the things, and its turned out as green bar. everything is ok, but while power on my device it will only shows the micromax logo it wont go further... kindly suggest me about what to do next...
