[Question] Blu Dash 5.0, unable to restore backup using SP Flash. Drivers issue?

[aus9]

ok can you also upload and link to your original boot image.

some facts discovered from your original recovery image in no particular order
a) size of image 6.3 Mb
b) ro.build.id=IMM76L
c) ro.build.date=Вто Янв 29 11:51:46 MSK 2013
d) ro.product.model=Full Android on Emulator
e) from init.rc...... write /sys/class/android_usb/android0/idVendor 18D1
from initrc...... write /sys/class/android_usb/android0/idProduct D001
f) from init.usb.rc.....write /sys/class/android_usb/android0/idProduct 0C01
from init.usb.rc.......setprop sys.usb.vid 0BB4

comment vid = idVendor

comment 2 built in Russia on an emulator
recovery builder does not do any quality control
----means can not use adb in stock recovery
comment3 build id claims to be a Motrola XOOM phone
comment4 vendor id claims to be a google phone or a HTC

#############
I have built a ctr1 which will also fail until I see your boot.img for the same reason. That is....in recovery mode ....adb needs consisent ids that match across files.
###########
but if we do not use adb in recovery mode....it should work for filesystem
clearing of cache and data and davlik cache
---which is what you should have done between each ROM flash IMHO
-------but I don't use windows and so don't know flashtools

#####################
I would like you to use fastboot which I claim does NOT need any windows drivers.....and you are going to prove it!

first read this post on sideload

[Only registered and activated users can see links Click here to register]

download the first link from Packages needed

ignore next download and jump to Windows adb command preparation

assuming you are a windows user.

and set up adb and fastboot but see this line

1. Connect your phone to PC with USB debugging enabled, and drivers installed.

ignore drives installed.....fastboot does not need any.
ignore usb debugging as you are in boot loop for normal boot up

###############
now download my ctr1 allegedly for your device

try at own risk
size is 5.6 mb so there is no way its going to overlap any other flash area
and "in theory" should be safe to flash.

[Only registered and activated users can see links Click here to register]

copy that download into the folder where you run adb/fastboot from
or if you did the Optional instructions you can leave it in your download folder.

###############

how to flash a recovey in fastboot mode

1) on your phone you need to use buttons to get to bootloader menu
and either that will take you direct to fastboot mode or offer a menu

2) if you are in fastboot mode on phone then on PC with cable connected
commands as admin as folllows

Code:

fastboot devices

you must see a device name it will be something like

mt6572_phone fastboot

only if you see this or a similar device name then you can flash with

Code:

fastboot flash recovery ctr1

your result will differ from mine but will look a little like this

fastboot flash recovery ctr1
sending 'recovery' (5156 KB)...
OKAY [ 0.132s]
writing 'recovery'...
OKAY [ 0.714s]
finished. total time: 0.847s

good luck

PS don't forget to link to your boot image

PS2...if fastboot fails Athos will guide you on hopefully how to flash ctr1 using flashtools

but I may have to rebuild ctr1

[dolence]

Ok, give me some time to process all this infos! hahaha
I have a small knowledgment about linux and freebsd. I mean, I'm not just an average windows user... If it would make things better to both of us I can setup a linux or freebsd box. Let me try what you just said first

A huge thank you!

PS: how di you knew I was going to forget the boot.img?

EDIT

nope the boot image has the same USB ids as my ctr1

continue your reading.

[dolence]

Ok, updating.... I did the fastboot setup.

1) on your phone you need to use buttons to get to bootloader menu
and either that will take you direct to fastboot mode or offer a menu

No matter which buttons combination I use, nothing comes on screen. Even when the phone was functional I couldn't enter in download menu. Device isn't charging, but still being recognized when connected to USB port and each 1 minute or so I hear that usb device insertion sound.
There is any other way to achieve download mode? I think I can dismantle the device if needed.

PS: fastboot devices show nothing

[aus9]

try another way then

you will need to use linux with either a debian or *buntu style distro
OR
windows with adb and usb drivers installed
#########
name the linux cd you have please
############
we need to setup adb using ids I will supply to you later
#####################
but if you can....see if you can install the Windows USB drivers that I told you to ignore in my last post.....

1) reboot phone into recovery mode....it should still be the stock?
2) data cable connected
from windows terminal do this with admin powers

Code:

adb devices
(must see a device...it will have a serial number)
(stop if no device device)

adb reboot bootloader

(either a menu appears to allow you to get to fastboot or fastboot appears on Android)

fastboot devices
(must see a device)

fastboot flash recovery ctr1

fastboot reboot

last command will reboot phone....when recovery reboots use buttons to get into new recovery

if too slow to get to recovery....remove battery
install battery and use buttons to get into new recovery

good luck

I've been strugling the last few days without much lucky. Cant' get the device listed ind adb or fastboot. Tried in Windows 8.1, Windows 7 and Windows XP. Phone is dead, doesn't boot in download or recovery mdoe, doesn't charge battery... my last hope is trying to get the device listed on linux or dismantle the phone and search for serial tx/rx pins.

[mirandam]

Without intending to get in the way of aus9's good intentions, if your phone is "near" dead, one of the most probable ways to get it back to life is by using sp flash tools. You say it's still recognized so it can still be flashed by flashtools, so stick with the windows xp and flashtools.
To bring back your phone to life, flashtools doesn't need to have adb working, it uses the preloader drivers (which is not the same as the phone's preloader) to communicate. These are the ones activated when connecting your usb to the phone when you flash or readback in flashtools.
Your phone doesn't charge or get into fastboot/recovery so it is likely the preloader is shot-off into neverland.
Since you have a complete backup, first thing to do is flash the original preloader using flashtools in download mode.
Next you should flash mbr, ebr1 and ebr2. Then uboot (or lk.bin) and logo.
At this point if you reboot your phone you should be able to get into the recovery menu using the appropriate key combo. Do not try to activate any of the options, it will not work since the recovery.img still needs to be flashed.
That will be the next step, just stick to your stock backup for all of this, later you can try custom recoveries. First thing is to get your phone working again so you should always stick to your original backup.
After flashing the original recovery, see if you can get into it, if that works, flash the rest of your backup and it should bring your phone back to life.
I would advice against dismanteling your phone at this point. It might provoke more problems then needed, just have a bit more patience.

+1 to mirandam

if you can't get into bootloader or recovery mode then
fastboot or adb are denied to you.

so you must now follow her excellent advice

good luck

[dolence]

I see. I'm sorry for my lack of patience, you guys are right and I will try to follow your instructions. My main concern is I'm not being able to get the phone writed in Flashtools. I already tried dozens of drivers, always removing the last onde used via usbdeview and rebooting. The driver never show as USB Preloader, always as MTK USB PORT and it gets disconnected and reconnect each 40 or 60 secs. Flashtool never give other result beside red status bar and 5054 error. That's why I was considering some drastic measure.

[aus9]

it could be that the battery is so weak it instantly shuts down or attempts to reboot.

Actually I think this might be the case for my tablet but I get a charging icon.

I gather you get no charging icon?

If I am right then,see if you can get a friend with a smart charger to recharge battery then try flashtools.

PS I mentioned post 5 section 5 ....preloader so I do care occassionally for windows and flashtools users
