[FIX] Restoring Flashmode

Some phones for unknown reason can't enter to Flashmode (Vol Down + USB = green LED)
This mode obliviously required to flash stock ROM via Flashtool / PC Companion / SEUS

When try to enter it nothing happens and phone just boots for offline charging.
Yeah, there is stock CWM-backups, but anyway broken mode is not good.

I did some research with user that had this problem and found cause.
Somehow 4th partition, s1sbl1 contain wrong data – it mismatch with OK phone.
Seems there stored loader for dealing with firmware.

After restoring good partition dump Flashmode works!
This helped 2 people, so I want to share this widely.
Do it on your own risk.

If you have recovery (CWM / TWRP)
1. Download attached ZIP
2. Copy it somewhere on phone
3. Flash it via recovery like any other ZIP
4. Done, flashmode will work

If you have only root
0. Not rooted? Use Towelroot for 4.3
1. Download attached file 1.img
2. Copy it into root of internal storage
3. Install app Terminal Emulator
4. Launch it and enter su
5. Allow root access
6. Very carefully enter this (wrong last number will brick device!):

Code:

---

dd if=/sdcard/1.img of=/dev/block/mmcblk0p4

---

7. Done, flashmode will work

[Help] Can't enter flashmode

I recently wanted to revert back to stock, but my volume down button is broken so I can't enter flash mode.
Is there any way to enter the mode differently?

Broken button. Can't enter FlashMode.

Hi, i want to flash stock ftf but vol- button in my xperia is broken. Is there any way to do it without flashmode or run it via adb or something.
