!!!DANGERS WHEN FLASHING PHONES!!!

[Ice Dragon]

I have flashed 5110-5.28 with 5110-4.51 when I was experimenting on reading the whole eeprom content via cable.

Upload was successful but phone is dead!

It can't be reflashed back since the phone wont even respond to turning it on (battery is full, tried on a separate 5510).

Phone is now only good for salvaging some components like sim holder, battery, flash, eeprom, etc.

I suspect that the flash I uploaded was not compatible to the processor on the phone itself. Or the original address where the processor is pointing in order to operate the phone properly now has an invalid entry point. Thus a dead phone.

Nope, I'm not crying for help on how to fix it. Only way to fix this is by sacrificing another 5110 with working flash, eeprom and cobba which is equivalent to buying another phone without worrying if it'll work or not.

Let this serve as a warning to experimenting with flashing your phones with different flash/firmware:

! ! ! DO NOT FLASH YOUR PHONES WITH OTHER FLASH FILES ASIDE FROM THE SAME VERSION ! ! !

Best regards to all.

This is a weird situation... But I dont
entirely agree with what you say. Maybe phone
have other problems in the First Place
because even if you erase full flash from
phone, Dejan flasher will still detect it.
I even uploaded 6110 flash file to a 6138
phone, and phone powers on but all locks are
closed off course...

I dunno, all was alright during the flashing.

"Done!" it said.

But the phone wont turn on. Won't respond to a reflash, or a power on.

BTW, X-Shadow do you still have a copy of that schematic for the Pony Prog? The one that can read/write the 24Cxx without desoldering?

Thanks in advance...

just use the I2c compatible cable connect it to parallel port (its in the LANcos web site)

[X-Shadow]

Starting 3210 v5.36 (and some of v5.31)
and 5110 v5.30 (and some of v5.28 and v5.29)
You need to desolder EEPROM already, but
for lower versions, you can read and write
without desoldering, just plug charger to
phone even without battery and connect any
EEPROM TSOP adapter.

Hi Ice Dragon

I Totally agree with X-Shadow you can throw any full backup at any phone and the worst case senario will be "Software ASIC Mismatch which basically means wrong software for this version of phone, all I could think it could be is a flat battery, or you should remove battery, even when flash is absolutly empty on production line the phone will still respond to flashing, even though its faster flashing than we do at 12Volts, or maybe as X-shadow said this phone has another problem.

I have some scrap phones that I have reflashed and played around with scores of times with no problems that you have got, even the same version as you 5110-5-28 flashed with 4.51 and it still responds

Hope this helps mate

Thanks everybody, still no go.

I got hold of another fully charged battery and put it on the dead phone, still no response.

You see, my problem is if I could not put the phone to respond to a power on when flasher asks for it, it could not proceed to re-flashing it back.

It displays the message "Phone not respond" since it does not indeed respond to power on.

I tested the flasher cable with another 5110 and works fine. Read or upload. Full or partial. Everything's fine. Except, I didn't flash the other phone with another 4.51 version, coz I'm afraid it will kill the other phone too.

Didn't experience any power surge either. PC is on UPS.

Oh well, that's that.

Thanks all and best regards.

You can read/write eeprom from old phones (without eeprom emulation) with this prog by Mbus cable.
