HALLELUJAH!

I was able to get BLUETOOTH working again on my R3A T68i Wohoo.. It has to do with forcing a wipe of the AVR by giving it a 2 MEG NULL file, then forcing it to take the original backup AVR file..

Don't know if it will work for other people but it sure save my phone's bluetooth.

@funks
great to hear you got your BT working again on that R3A.
I am wonder how did you come up with the NULL file?
I have also read on a manual, that states AVR holds the functions of the phone, and ARM is for stuff like IR, and BT. Below is what it states:

Some flashing tips and what is “AVR CPU” and “ARM CPU”
Inside new ‘original brand’ SonyEricsson phones there is two processors (CPU’s). One is Main CPU and this is AVR chip, and the second is Modem CPU and this is ARM chip.
The Main CPU (AVR chip) is holding almost all phone functions, including language packs available. The Modem CPU (ARM chip) take care of Infrared communications (IRDA), Bluetooth and Data/Fax functions.
On ‘non original’ SonyEricsson phones (this are A3618 and R600) there is only one Main CPU (an ARM chip). Also on latest models ‘original brand’ T200 and T300 the Modem CPU (ARM chip) is no more present.
When flash a phone, usually is enough to flash the Main CPU (AVR chip). The Modem CPU (ARM chip) is needed to be re-flashed only when upgrade T68m to T68i or when make major version upgrade (e.g. from R2A to R5D or so on). If there is any error in “Connect” or “WAP services” menus, or if phone hang-up when try to enter any of this menus, a flash update for Modem CPU (ARM chip) is needed. Also the Modem CPU need to be upgraded if there is any errors in Bluetooth functionality. In all other cases, the Modem CPU no need to be upgraded.

Well, I hope that helps a little, I am very tempted to flash my R4C with ARM only from one of those flashes that reported to work.
I am also looking for a R5 version of firmware that has English and Simplified Chinese language, I hope somebody will dump one.

Other than that big thanks to all who put money/time/enegry into this issue.

Was up all night trying to get my phone back thankfull that the restore got it back.

As for the NULL files - the file were simple to make

dd bs=2k count=4096 if=/dev/zero of=T68i-AVR.bin
http://www.pocketbuddy.com/gdaswani/T68i-NULL-AVR.bin

dd bs=2k count=1024 if=/dev/zero of=T68i-ARM.bin
http://www.pocketbuddy.com/gdaswani/T68i-NULL-ARM.bin

BTW, if you guys have the original firmware for your phone (if you backed up), you can also flash the phone using the "KILLAVR" method (to restore BT functionality) and use the your BACKUP AVR file as the file source.. (Just make sure losFile.bin is still there and has a full record on the "recover" button just in case)..

[KILLAVR METHOD]

KILLAVR
Start 0000-0000
Length 0080-0000

Pick your backup AVR file then FLASH SW

after doing so

flash your ARM chip with the NULL ARM file (check the link).

Flash ARM chip
Start 0000-0000
Length 0020-0000

Turn on the phone and do a master reset (phone will still be buggy in said mode and master reset probably won't finish, just turn it off after two minutes)

Re-Flash your ARM chip again with your BACKUP ARM file

Flash ARM chip
Start 0000-0000
Length 0020-0000

See if BT works..

Unlocking has the Version 7 of the client available for download now, dunno how well it works as I used 6.52.

Funks,

Just have a brief look at the EC V7 and I believe the V7 remove the support of IMEI change.

Hey, on your last post on the mishap with the latest flashes, were bt and ir turned off? Did you do a master reset?


Hi,

I messed up my R6B t68i when flashing to R5C001. Here's the thing: I don't know if Bluetooth was turned off. I normally keep it in Automatic mode, and it may have been left there. I did NOT do a master reset. I was kind of thinking that it didn't matter, since all the settings were going to be overwritten anyway.

What I did do was backup the firmware. Using Funks' method, it seems I could have fixed it, but the phone's gone to a better place.

I don't know whether or not it's important to do a master reset or turn off Bluetooth, but I certainly do them now. One thing I've noticed is that if you turn off Bluetooth before doing the master reset, the phone is back in Automatic mode after the reset. So, turn off Bluetooth AFTER the master reset.

Hi
Anyone succeeded in flashing a T68 H/W and S/W R1B to R5D without BT and battery problems? If so, what software did you use and where did you buy your logs? And where did you get the firmware?

Also, how can I know if my T68 is m or mc? At the back it is written T68m but in the menu language I can see English and Chinese.
Please help.
Thanks

Funks,
I noticed the version 7 from unlocking as well but is this the real thing though? I checked the gsmhacking.com, they still have 6.55 as the lastest client and most of log-sellers i know use version 6.51 and 6.52.....
