[General Questions and Answers] marus2:
Hi there.

All, who want to turn on their phone, this won’t respond to anything and after connecting to PC, many partitions appear and phone is connected in device manager in windows as QHUSB_DLOAD (or similar) are welcome here.

Congratulation, you have an soft brick in your hands.

But it isn’t as hopeless as it seems, your phone can be repaired.

There are two methods how to restore phone. Easy and hard :)

Easy way:

Not tested. The theory is, that phone won't start because it have damaged MBR sector. So goal is to get a copy of MBR sector from worked phone and flash it to damaged one.

It should work :angel::D

It's a pitty, that easy way is still under some developing and here is the hard way.

Edit: Try to flash file from post below from fazerg and give some feedback. If it works, whole hard way is not needed to do. But, still not tested.

Requirement:

-	Linux system (for example portable Ubuntu) - http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows

Before preparing USB stick, try if it is visible in your BIOS. My 8GB stick won’t, so I have to use some old 4GBs. After this, some BIOSes need not only to make boot priority to removable devices, but you have to prioritize USB in HDD boot priority.

-	Some knowledge about disk partitioning

-	Patience – lot of patience

Let’s start

-	Boot linux.

-	Connect phone – the blue LED should blink.

-	Wait until new disks is connected (the time is always different, I don’t know why, sometimes it is almost instant, sometimes I have to wait 30 minutes). The phone may constantly mount and unmount, don’t worry, it’s normal behavior for phone in your condition.

-	After you have stable connection, press ctrl-alt-t (run terminal window).

-	Type

sudo su

you gain root access in linux.

-	Type

fdisk –l

You’ll see something like this (try to read the whole message, real output is very long).

/dev/sda – your system disk

/dev/sdb – your data disk (if you have some)

/dev/sdc – USB stick with linux

/dev/sdd – phone

And a warning message:

WARNING: GPT (GUID Partition Table) detected on '/dev/sdd'! The util fdisk doesn't support GPT. Use GNU Parted.

For now you are interested in /dev/sdd

- type:

parted /dev/sdd

Then inside parted just type

print

Some error message would appear, just type o or ok

You should see table like this:

That's all in parted, just type

quit

Then you must save these partitions 13 – modemst1, 14 - modemst2 and 22 – persist. It contains your unique IMEI and MAC addresses of WiFi and Bluetooth.

You can do it this way:

Create folder on your hard drive or probably on your bootable Ubuntu USB if it has enough space to do it. Let say we call it v5backup.

type:

dd if=/dev/sdd13 of=/<disk_where_created_folder>/v5backup/modemst1
dd if=/dev/sdd14 of=/<disk_where_created_folder>/v5backup/modemst2
dd if=/dev/sdd22 of=/<disk_where_created_folder>/v5backup/persist

Great, you have saved very important information. Do not share them with anyone – It can bring you a problem if you have two mobiles with the same IMEI.

Note: As a backup path do not use /dev/sdb but path, which you see in file explorer like /media/name_of_drive/DATA

Optional, but very recommended step: Make backup of a every single partition by typing:

dd if=/dev/sdd1 of=/<disk_where_created_folder>/v5backup/modem
dd if=/dev/sdd2 of=/<disk_where_created_folder>/v5backup/sbl1

and so on…

So let’s restore.

1)	Find someone with the same phone – in this case ZTE V5 2/8GB.

- Set donors phone do fastbootmode (turn it off, press vol- and power), then go to last line – Dload mode. Then connect it to PC

- Type

dd if=/dev/sdd of=/<path_to_where_you_want>/v5backup/full.img

This makes full image sector by sector of donors phone.

- Wait until done - beware of choosing destination folder – full backup would have about 8GB, so you have to have enough free space.

- Turn on donors phone (about 20 sec press power button).

2)	Connect your phone, wait until it connect, and make reverse step

- Type

dd if=/<path_to_where_you_want>/v5backup/full.img of=/dev/sdd

- Wait until done.

- Buy donor some beer :D

After flash complete, don’t disconnect phone, LED begins to blink and after some time (maybe 5 minutes), phone should begin to recharge from PC’s USBport.

If you haven’t donor to give you a phone, I can upload my backup. BUT, it is 5GB file, I don’t have such big storage to upload. And, I made this step in windows by using HDDraw copy tool, so this file will be unusable in linux.

After your phone restart, you can see, that it is the same as donors :) Didn’t I say, it’s a bit copy? Unfortunately, you can’t make a call or connect to Wifi, because you lost all NV information. Let’s restore them…

Reset your phone into fastbootmode (turn it off, press vol- and power), then go to last line – Dload mode, connect it to PC and type:

dd if=/<disk_where_created_folder>/v5backup/modemst1 of=/dev/sdd13
dd if=/<disk_where_created_folder>/v5backup/modemst2 of=/dev/sdd14
dd if=/<disk_where_created_folder>/v5backup/persist of=/dev/sdd22

That’s all. Now, you should have fully worked phone with dual sim, WiFi and Bluetooth worked. Congratulations :fingers-crossed:
