Converting to CID52 (Z550a)

[a123456789]

I accidentally convert my Z550a phone from CID51 to CID 52 by using XS++ 3.1. The XS++ said that if You Upgrade To CID52, You Can Not Revert Back To CID49 Or CID 51.

Anyone can have advice how can I revert back? I really appreciate your help.

Reverting back to a lower CID is not possible.

So you mean that phone is totally dead. Is there any way to restore it? or flash it by CID51's mbn, fbn? Because there is no CID52 firmware for Z550a.

Hmm...could you please post up the identify log of SE Tool and/or XS++?

Have you tried SEUS yet?

[interferej]

i think that is only one way: waiting for new soft available in seus or of course in topsony:(

I have tried SEUS, it does not work.

[docmagoo]

you cant revert. I have done extensive research into this and no joy!!! the higher CID loaders wontaccept the old CID firmware

[jasmin]

If your phone is cid52, you can`t use files that are for cid51. You need files for cid52.

Nice day

Hi Justme,

I trust you. I post all log files. I am waiting for your answer.
By the way, do you know some tools can convert the mbn, fbn firmware files from CID51 to CID52 format?

[a123456789]

I can not flash the FS. Please let me know where I can get FS (CID52) for my Z550a phone.
