Still showing the same error: "S_BROM_CMD_STARTCMD_FAIL (2005)". Please tell me what to do.
Another thing, when I connect my A25 phone without battery, the device manager list updates itself every two seconds: once it shows the preloader vcom port and then in the next refresh there's no vcom port and this process repeats. Any idea why?

Follow the same procedure with this drivers http://www.mediafire.com/?31nddwqdot5ajp2

Follow the below approach to install the drivers on Windows 8:
1. Go to the right bottom corner of the desktop and wait for the side menu to appear. When it's there click on the gear icon with the title "Settings".
2. Now click on the entry "More PC Settings", then click on the entry "General".
4. Scroll down to "Restart now" (under "Advanced startup") and click it.
5. Wait a bit for a menu.
6. Now click "Troubleshoot", then "Advanced Options" and after that click "Windows Startup Settings".
7. Click on "Restart" and wait for the profit to happen.
When the computer restarts, select the option "Disable driver signature enforcement". After it finally booted into the operating system you can install the unsigned driver. After you've installed the driver reboot once again and you're done.

It did the same thing with my MT6577 (Wiko Cink PEAX), so I connected it with a battery and without holding VOL+. Then "MT65xx preloader" appeared in device manager then disappeared (once). It is normal that it disappears. When you start Flash_tool and when you click Download (or whatever you want to do) THEN you connect the phone (in off state), and the flash operation will succeed.

MT65xx Driver
MT65xx Drivers guide
press thanks if it works

Well.
I've posted in other similar threads today but its because i really need help - running out of alternatives.
I've partially bricked my THL T200 - it is stuck in bootanimation after i removed gallery.apk from the rom using TitaniumBackup.
Already tried all those flash methods in different sequences (with battery, without battery) but my phone just connect\disconnect all the time - i can't even install the VCOM driver.
I've TWRP installed - is there any rom for this phone i can flash using this.
All i want is go back to stock.
Thanks in advance for any ideas !

[TUTORIAL]How to root Alcatel 918N (HARD WAY) when Superoneclick and Unlockroot fails

NOTE: I will not be held responsible on anything that may happens to your phone... This proceedure is to DO IT ON YOUR OWN RISK!! and rooting the phone may void your warranty ..
Its better to try Superoneclick and Unlockroot procedure first before you try this!! this is just your last option when you think both fails to root your phone.
These are the steps I did to successfully root my cheap Alcatel OT-918N (white from SUN Carrier Philippines) in chronological order.
Credits should go to breakk and his team and the forum where it was posted http://www.movilesdualsim.com/foro/threads/9022-TUTORIAL-ROOTEAR-ALCATEL-OT-918-D-(Android-2-3-5) This is the 3rd procedure they suggested I just translated it.. Thanks a lot mates!!!
Download all and follow all instructions carefully:
1. Drivers MTK6516_PL-2303_para_XP, vista y win 7.rar--- http://www.mediafire.com/?32e6q4fzx7ahoeh
2. 918D system.img (pass: breakk.movilesdualsim.com)--- http://www.mediafire.com/?f4dahqmmucqha9c
3. flash tool and scatter.txt --- http://www.mediafire.com/?9w5b5h1ywseljrr
4. EXtract all downloads to a single folder that can be easily located.
5. Backup your files
6. make sure the phone is charged with enough battery then turn the phone off
7. while its off connect the phone to your PC using a USB Cable
8. An unknown device will appear instantly
9. choose to update driver manualy.Depending on the OS you have (xp, vista, 7) install the appropriate driver from STEP 1.
10. If you installed the drivers correctly UNPLUG your phone and you can now proceed to the next step
11. run "Flash_tool.exe" from the extracted files

13. browse for the file MT6573_Android_scatter_Alcatel_OT_918D.txt select it and click open
14. it will gives you an ERROR [WARNING HINT] JUST PROCEED and click OK
15. a list will appear, scroll down and CLICK the BOX beside "ANDROID"
16. then double click on the word "Android" and browse for the file system.img (the file you downloaded in Step 2) and open it
17. Now click the button Download in the top of the flashtool window
18. This will initiate a 15 second countdown at the bottom of the window, plug the 918N in the usb port during this countodown (the phone must be off)
19. You will see a yellow bar @ the bottom, wait until it goes reaches 100%. Once this is done there will be a message that will report that you successfully completed the process,also a green/white circle will appear in the flashtool and on the screen of your mobile the battery charging indicator will appear. UNPLUG the phone from the usb port and press the POWER. The phone will start and the Android logo will appear, now just wait a few minutes without touching anything on the phone (buttons or touchscreen), it will take some time to load the system.img. Once the screen displays the menu that asks for password the for 2 SIM cards you are ready, you have succesfully rooted the 918N!!! JUST HIT THE THANKS BUTTON

I did not continue because when I plug in my phone while powered off I see only "MTK65xx Preloader" and another unknown device. The unknown one disappears forever. I chose to manually install the driver for MTK65XX preloader thing with the mobileuncle one. When I reconnect it Windows still tries to install the driver. This might be because the drivers weren't properly installed.
I'm not risking it until this one is cleared up XD I know what to expect from the flash tool, but the driver installation in Windows is unclear (windows itself, not this tutorial)
Edit: LOOOOOOOOOOOOOOOOOOOOOOOL I don't know what I just did. I tried Easy Rooting Toolkit and SuperOneClick (again) and magically my phone got rooted. LOL. Dunno what happened there (other than enabling everything under "Development"). Thank you, heavens.

You can reinstall the driver again when it ask you the second time. And once the driver is not installed it will not established a connection to your phone and the flash tool will give you an error saying no device is connected. It will abort the flashing process so nothing will be flashed and all will be the same... The only thing you should be afraid of is when the yellow thing runs and you accedentally stop the process before reaching 100%. And lot of courage is needed as well. Hahaha

And the MTK65XX Preloader is the driver you need to install. When it popup dont choose search automatically, choose the other one and manually locate for the drivers youve download

Sir Jbazt_katuforzs i'm using windows 7 32bit i just can't install the preloader driver and i don't know why. Tried the exe installer and manual but still when i'm connecting it on data cable it can't find the preloader like what "kpbotbot" 's experiencing. The Manual installation is loading a modem driver for the device.

Choose the driver depending on your OS. Did the pc recognized an unknown device when you plug the phone while its off? If not the previous drivers you've installed from superoneclick and unlockroot messes the ports. Try to install it on a different pc running xp. It will only take you 5-10 mins
thanks
at last! I'm rooted! THANKS A LOT!!
thanks for this very reliable and detailed information.. got my unit rooted

hi 4trackmind,
i'm interested in the new 2.3.6 kernel. can you try the steps posted here? www symbianize com/showpost.php?p=11514350&postcount=1
there are 2 sections on that page, flashing a custom recovery image and rooting by using an update. do tell us if both sections work.

Thanks a lot i was able to root my Alcatel glory!!! next stop installing a ROM
2.3.6 and Rooted..
just want to share, i successfully rooted my OT-918N from SunCellular PH with Android 2.3.6 using the following scatter.txt and recovery.img file.
the procedure is the almost the same. skipping the loading of system.img as we are only after the custom recovery to be able to install superuser and busybox.
another thing is i set the flashtool to USB Mode instead of scanning to com ports... hope you get the same results as i did.

[TUT] Instructions MTK6577 USB VCOM Driver Installation

Since here every day again and again problems with the USB VCOM driver installation for MTK6577 appear Phones, here is a short guide to the installation, and a final, successful test with SPFlashtool!
Installation of the USB VCOM driver:
[1] With USBDeview, clean up your PC from all possible old MTK VCOM entries, then reboot your PC.

[2] Smartphone is switched off, and still dont connect via USB to the PC.
[3] Open Device Manager and leave it open!
[4] Your switched off Smartphone with inserted rechargeable battery via USB connect now on the PC, you should now see a MT65xx preloader in the Device Manager.
(With some MTK6577 Smartphones should be installed without battery. Please before hand inform.)
[5] now launch the Installdriver.exe from the unzipped MT6577 USB VCOM drivers folder. Confirm the installation of unsigned drivers
[6] now! (W7 x 64 this confirmation comes later in the manual installation!) After the installation is complete, you have no entry in the Device Manager, it is correctly!
[7] PC reboot!
[8] Open Device Manager and open the switched-off Smartphone via USB to the PC release, now connect (same USB port!)
[9] Now a MediaTek PreLoader USB VCOM should appear for a brief moment in the Device Manager entry!
[10] At the moment the entry double click and click on "Update driver" under the tab "Driver".
[11] With the wizard in the unzipped MTK 6577 USB VCOM drivers navigate and select the folder for your operating system.

Don't worry about that "unknown device"
You can connect your phone and continue to Flash.
If driver is not there for your phone then SP Flash Tool will keep on searching for your phone.
If driver is installed then SP Flash Tool will continue and start Flashing your phone.

Hello All,
I tried both on window 7 & 8; 64 bit and procedure as mentioned by the OP is perfect; however i am posting it again here
1) Download the flash tools from anywhere preferably most updated one: SP_Flash_Tool_v3.1224.01
2) Download the recovery which ever you like TWRP / CMW (I tried both of them now and they are working for me on MMX A110)

Hello All,
I tried both on window 7 & 8; 64 bit and procedure as mentioned by the OP is perfect; however i am posting it again here
1) Download the flash tools from anywhere preferably most updated one: SP_Flash_Tool_v3.1224.01
2) Download the recovery which ever you like TWRP / CMW (I tried both of them now and they are working for me on MMX A110)
3) In your desktop / laptop please ensure you allow installation of unsigned drivers (youtube will help for this)

Plz can anyone post video tutorial of installing this rom do favour
I've followed ALL the instructions word for word now and still can't get it to install the MT6577 drivers correctly. I've tried the OP's method as well as apoorv.mehrotra's method. Have rebooted my PC now 28 times! Still can't get it to work. I have exactly the same problem as everyone else - the phone appears in device manager for 3 seconds then disconnects suddenly. Even the legacy installation method does not work. I've tried on a Windows 7 64-bit machine as well as a Windows XP 32-bit machine - exactly the same outcome each time.
Help!
It worked on my windows 8 x64. To install these drivers you need to bypass driver signature enforcement. Follow the instructions at http://www.craftedge.com/tutorials/driver_install_windows8/driver_install_win8.html

Sp flash tools have got no issues with window 8.

FIRST HAVE YOU UN-INSTALLED ALL THOSE DRIVERS THAT ARE PREVIOUSLY INSTALLED IN YOUR PC?
AFTER UN-INSTALLING FOLLOW THE STEPS MENTIONED IN THAT THREAD.
AND SECOND...IF IN 5th STEP NO DRIVERS ARE BEING INSTALLED THEN SIMPLY JUMP TO 6th STEP.
OH YES...I FORGOT..
SIMPLY CONNECT YOUR PHONE IN SWITCH OF MODE AND PRESS AND HOLD THE VOLUME UP BUTTON.THIS WAY YOU WILL GET INTO META-MOD AND SP FLASH TOOLS WILL DETECT YOUR PHONE AND YOU WILL BE ABLE TO FLASH RECOVERY.
AND AS THIS PROBLEM IS RELATED TO DRIVERS ONLY.....IT IS SUPPOSED TO BE DISCUSSED IN THAT THREAD AND I DON'T THINK THERE IS A NEED FOR A SEPARATE THREAD. .......so it will be better to discuss in that thread and close this one.
hitting thanks is not charged by xda...so wanna try how it feels??

Sorry didn't got you : that mtk drivers has no way to install.
Simply download and install these-:
download and install the following drivers on ur pc.

MTK DRIVERS

And then.. click on device manager(on the left).if ur device is listed under adb devices then u have successfully install drivers. But if it is listed with a yellow sign under unknown devices then right click on it. Select update drivers and locate to the folder c/program files/micromax
this folder includes drivers and that will be installed.
HOPE THIS TIME IT HELPS YOU.
don't mind..... i don't know why but i am thinking that you are going somewhere wrong.
Because that meta-mod should have worked.
But also there can be a hardware problem (though it's chances are very less)... So still to check that change your usb driver and also usb port.

Create a new windows user with admin privileges and connect the phone and install drivers. After drivers are installed please use spflash tool. It will work.
Sent from my Micromax A116 using xda premium
okay, first thing you need to do to install vcom drivers is to disable the mandatory digital signature enforcement in windows 8.
(Yeah this is a stupid thing msft started with windows 8, the VCOM drivers are not digitally signed so windows won't install even if you have admin rights.)
Step 1. Go to the right bottom corner of the desktop and wait for the side menu to appear. When it’s there click on the gear icon with the title “Settings”.
Step 2. Now click on the entry “More PC Settings”, then click on the entry “General”.
Step 4. Scroll down to “Restart now” (under “Advanced start up ”) and click it.
Step 5. Wait a bit for a menu.
Step 6. Now click “Troubleshoot”, then “Advanced Options” and after that click “Windows Start up Settings”.
Disable the digital signature enforcement and boot onto windows.
To install vcom drivers, right click the file(64bit or 32 bit) and select install.
As for the bin4ry tool, it doesn't work on jellybean for rooting. You need to install custom recovery and flash the supersu zip file.
Hope it helps.

I too faced this problem once when i had bought a new canvas...but it was soon solved by installing drivers.
But your case is damn different.
Here i see no solution....
And please don't flood the inbox with same messages buddy.
I have a busy schedule these days and don't get enough time for xda.
If bootloader is locked then in any case your phone won't brick.
-download drivers or install by connecting your phone
-connect phone & start SP tool (without bettry)
-start download on flashtool after loading scatter file
-insert bettry
Hit thanks ,it doesn't cost anything

Soft bricked Panasonic P81

Hi Friends,
This is my first post at XDA.
I unfortunately bricked my Panasonic P81 after rooting it and adding XHalo app and the boot manager app from the Xposed Framework.
The situation is as follows-
I can get to the logo, it screams Panasonic and then doesnt boot. I dont have CWA installed and worse, my SD card which had my stock backup is also lost. This means I need a mechanism to stock recover and perhaps flash boot.img and recovery.img?
I am stuck at this point, not sure how to proceed. I can get to recovery, have cleaned cache, backed up user data ,done a factory reset. Even after factory reset it still cant boot.
Please help me with a step-by-step instruction to recover, this phone is dear to me. How do I flash?(boot.img or rom) I have downloaded Sagar Patel's (good bless him!) backup and the images, but need guidance on how to flash and recover.
Please help friends and apologies for any incovenience. I am still a newbie
Guys please help!!
Driver-USB-PC connection problem

Guys please help!!
Click to expand...
Click to collapse
Hope drivers are installed properly in your pc.
If you are going to use sp flash tool, Make sure SP flash tool is set to auto-detect com port, not manual selection
If you find that it is driver problem, following may help you.
Please note that there is nothing that much hard in driver installation as it is just to connect your device with your pc but because many users still face problem of driver installation, you can try following tricks!!!
It is observed by me that driver installation and adb interface problem do not happen in windows XP as eventually and generally it is happened in windows 7 and later…so, you can simply try on windows xp if you are able to do so…(you can use dual operating system too!!! Or good relation with neighbor/friends/colleagues/someone/all can be beneficial here!!!)
Note that all tricks here are not necessary to work, but it may still work for you….
Take one by one step, if the first step does not work for you, only then try next step. This is not all steps to be taken at once type guide…This is simply Try and error type tutorial/tricks…
There are following problems I have come to know regarding to driver installation and conflicts:-
Device is charging through usb cable but there is no usb option displaying on either device or no driver installation box/message/pop up appears in pc….
Missing sound of that usb-pc connection
Sound of disconnection after couple of seconds of connection
Adb interface is missing
Ok, sometimes changing usb connection type for example, from mass storage or mtp to camera, ptp, usb tethering or something else can bring adb interface…..
Try with different USB Cable. You can use original nokia or samsung tiny cable instead of cable having long length. Sometimes, length matters!!!!
Try in different USB Port.
Sometimes, you have to disable signature verification in your pc for proper installation of driver.
Had you disabled your antivirus before downloading, installing and while running your tools/softwares? You may need to do so…
Have you installed the software (or say, all associated softwares/tools) in C-System drive?, if not, then you should first install required software/tools in system drive that is usually C drive in Microsoft-Windows OS…or try after installing them on desktop.
Keep all necessary files/tools (driver files, flash tools, rom etc…) on desktop.
Download proper driver According to your model/device, According to chipset inside, According to Official site of manufacturer, Official site of chipset, through PC Suite/flash program of your device…
If the problem still not solve, you should try all available driver packages of your device one by one whether from official site of chipset inside your device, or any forum, adb, pdanet+ or foxfi, universal driver, VCOM Port driver, drivers from hexamob through play store, and find all possible packages and see if someone make positive result after installation…
If the problem still not solve, you should install remaining update packages of your system (PC) including all primary, secondary, essential, Non-essential updates….whatever, just install them all….reboot your pc…and see if problem is solved….
If you can connect the device but somehow found that device driver still not installed properly, just go to device manager in your pc, click on portable device, right click on your device and apply “Update driver”. Click on “automatically search” when a window prompt ask you.
If the problem still persists then,
Just remove all the drivers using usbdeview (I have given link also to download usbdeview in earlier post)
https://drive.google.com/folderview?id=0B511A2txfpAPbmwtQXZqbnVlT1U&usp=sharing
Install usbdeview and remove all the drivers
You can also fix this by showing the nonpresent devices in devicemanagement (google for show nonpresent devices for explanation)
Go to com ports, and delete all mediatek drivers except preloader driver. Now start over. It can help if you choose the same usb port where you had success last time.
Use Usbdeview to uninstall all the drivers before connection, restart the pc, Extract and keep driver zip files and other useful files/tools on desktop…just start your tool… and try to perform your tasks like backup…or restoring the backup…without worrying about that sound of disconnection you may listened after couple of seconds of connection or don’t even worry if you are just missing that sound of usb-pc connection….just try on your tool…
If still problem of driver installation persists, then simply use usbdeview and uninstall all drivers, restart your pc and try following steps:-
There are various ways to install proper drivers at the time of connecting the device with pc depending upon how you connect it.
Follow the procedure both with and without battery
Simply plug in via USB Cable
Connect by holding volume down button
Connect by holding volume up button
Connect by holding Power button
Connect by holding power and volume down
Connect by holding power and volume up
Connect by holding both volume up and down button
Connect by holding thrice volume up, down and power button
Connect by holding power and home button
Connect by holding power and menu button
Remember which method works and which drivers are installed
in LAN-Devices you may have different android device
Select/set drivers by hand and use the mtk usb driver, now Flashtool finds the phone
Suppose holding volume down method without battery works for you then what next you have to do is as below:-
1.TAKE THE BATTERY ,SD ,SIM OUT OF THE PHONE
2.HOLDING VOLUME DOWN CONNECT IT TO PC VIA USB(ONCE YOU HEAR A SOUND FROM PC YOU CAN RELEASE VOLUME DOWN)
3.OPEN DEVICE MANAGER(ON COMPUTER SEARCH IT OR CONTROL PANEL)
4.WAIT FOR 2-3 MINUTES
5.YOU WILL HEAR A SOUND & OTHER DEVICE WILL BE DISPLAYED
6.IN OTHER DEVICES ->MT65XX PRE-LOADER
7.RIGHT CLICK MT65XX PRELOADER
8.UPDATE DRIVER
9.LOCATE THE DRIVERS PROVIDED ACCORDING TO YOUR OS(VISTA,WIN7,XP)
10.IT WILL DO ITS STUFF
Install Mediatek drivers, preloaders, VCOM port etc…
Manually Install MediaTek USB VCOM Drivers
Requirement:-
1. Download MediaTek USB VCOM Drivers
2. Download USBDeview
Here is the link from you can get it:-

8. Click Open and OK. You will see the drivers listed.
9. Select your driver there (select Mediatek Preloader USB VCOM Port)
10. Click Next and finish installing
11. If SP flash tool or other software still dont detect your phone then also install Mediatek DA VCOM (consider installing more from the list of drivers one at a time if need be)
Try in different PC
Sometimes windows XP works when windows 7 fails!!!
Case:-
It did the same thing with my MT6577 (Wiko Cink PEAX), so I connected it with a battery and without holding VOL+. Then "MT65xx preloader" appeared in device manager then disappeared (once). It is normal that it disappears. When you start Flash_tool and when you click Download (or whatever you want to do) THEN you connect the phone (in off state), and the flash operation will succeed.
Guess what? Once my Panasonic P81 could install driver and got detected after approx. 5 hours of continuous connection with win 7 x64!!! Meanwhile, I tried first usbdeview and then manually installation of mediatek driver but manual installation had failed as my p81 was only charging when it was connected with pc….So, mediatek – windows 7 conflicts….but, when I tried tiny (very small) nokia usb cable, it works instantly…
If you ever meet problem when you connect your android with your pc via usb cable and find that your android is charging but could not recognize or there isn’t that options of “USB connection” then just disconnect your android, power off it, remove battery, connect it without battery with your pc through usb, let it have some time to recognize your android or hear that voice of “usb connection” you were just missing…after that, insert battery and switch on your android…you are done!!!
Sometimes removing both sim cards and battery and then re-inserting them after a couple of seconds also works.
Try with different USB Cable
Try in different USB Port
Try in different PC
Sometimes windows XP works when windows 7 fails!!!
Use usbdeview to remove all the usb devices and then add your device

In my opinion MIUI is best because it has a self large community like xda and launch updates per month so many that you will fed up installing them.....if you download and install one update you will be amazed that it will say 3 more system updates pending......and if you complain a bug next month it got fixed.....only thing is to find one...
PS don't download the miui 6 for p81..complained by many p81 user that it hard bricked the device.
And that miui is not official i.e. some developer made his own one and DO not tested that it works or not......
