[Q] Can not flash CM7 or CM9

[javlada]

Hello,

I have run into problems with my Defy+. I wanted to upgrade from CM 7.2 RC1 to RC2. But after the flash, I got the message in the picture below and the phone won't boot.

I have to flash the phone using RSD Lite. But now whenever I try to flash a CM ROM (I tried CM 7.2 RC1, CM 7.2 RC2 and the latest CM9 nightly) I get the same error. After that all I can do is to flash DEFYPLUS_U3_4.5.1-134_DFP-231_CEE_ROOTED_No_Signed.sbf again.

I think I'm doing everything correctly, I did it already many times. I install 2nd init, reboot phone to recovery, do factory reset, install CM and google apps. Everything seems to work fine. But when I reboot the phone I get the same error again and have to use RSD Lite to flash an SBF.

What can be wrong?

What CM7 ROM are you trying to flash??

As I already wrote I tried CM 7.2 RC1 and CM 7.2 RC2. Both with the same result.

I had CM 7.2 RC1 installed for a couple of weeks until today.

I meant the build. You tried the CM7 build for GB kernel??
Coz it looks like you're trying to flash a froyo ROM.


Doesn't matter from where I send it, what matters is written above

neo.ank> You're right. I was trying to flash a Froyo build. I feel like an idiot now. The official 7.2 RCs are only for Froyo. Now I managed to install CM 7.2 Quarx's nightly build without any problems.

But it still doesn't explain, why I got the same error with CM9 Defy+ builds. Anyway I can live with 7.2 hapilly, but I couldn't with the stock ROM.

Well I think I read somewhere about the base ROM affecting CM9 installation..not sure 'bout it..
Technically, it shouldn't give the error..

Which one did u try? Quarx or Epyz..Quarx should work on MB526 as its GB kernel..for Epy u may need to flash a froyo kernel.

Sent from my MB526 using xda premium

I tried to install Quarx CM9 build. Maybe I did something wrong. I'll probably try it again, when HWA will work completely.

I'm pretty satisfied with CM7 now.
