[Defy Q&A, Help & Troubleshooting] lamed:
Hi,

So I upgraded from cm7.2 to 10 on my defy green lens. After a long and difficult upgrade, almost everything works - except any functionality of the usb port...

I'll jump right into the real deal: without usb connectivity, I cannot try to flash other SBFs to fix it! I can enter the bootloader screen just fine (says 09.10 on top, I believe that the last SBF I flashed was 3.4.2_179-002 , as recommended, before I rooted it, 2ndinit, and sucessfuly installed cm10) and the phone recognizes when I plug in a usb cable to it. but the computer always shows up a "usb device not recognized" error, and I tried on two machines, winxp/win7, and several different usb cables. I read some threads about crashing drivers between rsdlite and different tools motorola made; I never installed any of that junk but just to be on the safe side I removed all drivers and started fresh. still no go.

______________(That's the problem, now I'm just going to give more information about it)______________

The phone does not charge off a computer nor from a wall charger, with an assortment of different usb ports, cables and chargers. when connected to a computer (whether the phone is on or off) a "usb device not recognized" message comes up, on both windows xp/7 (different machines.) Seldom, when connected to wall charger, I can get the battery icon to show charging for about a second, (after a restart and plugging in to the pc briefly beforehand.) If I'm so lucky to make that happen, either it goes off in about one second, or it will change statues from charging to not charging several times very rapidly and then stay on not charging.

If the phone is off and I connect it, the white led sometimes come on, and then the phone comes on- presumably to go into battery charging screen, but instead it boots up normally. (this may be the correct behavior with this rom. idk.)

If you care for more information, let me elaborate about what I mean by "After a long and difficult upgrade":

I previously upgraded to cm10 (30/7/2012) CM10-20120730-NIGHTLY-mb525.zip,

but downgraded shortly after, back to 7.2. (I decided to wait for something a bit more functional)

Back then both the upgrade/downgrade went fine. This time I got into a bootloop (or stuck on bootscreen) after updating to 26/03/2013 God's version (oops I meant Quarx's version.)

Trying to use my nandroid backup for 7.2 I got a md5 mismatch and even after generating a new md5 file I couldn't restore /data.

Moving on. using CWM I tried installing some kernels (kernel-froyo-222-179.zip, and same thing but signed,),

then a fixed sbf (not full) 3.4.2_177-Fixed.NORDIC_DEBLUR.sbf,

and a very crappy sbf JRDNEM_U3_2.26.0_BLUR_P3_SIGN_SIGNED_USAJRDNEMARAB1B5TEL02A.0R_USAJORDANTELSTRA_P033_A017_M008_HWp3_Service1FF.sbf

** this one almost gave me a heart attack, after successful flash defy black screened with no LED indications. I was able to work my way into the bootloader and flash another SBF with rsdlite, without any indications from the device. lucky me.

Then I flashed the sbf I mentioned above and that's how I eventually got into cm10.

I can't even downgrade to stable cm7.2. Tried flashing a fresh install through CWM (wiping everything before and after, of course) and ended up stuck on boot screen. I don't know if it has anything to do with CG numbers or what, but I really can't figure out why CM7.2 wouldn't boot on the same SBF CM10 is booting fine right now.

I can't also share the SD card through CWM. (-> device not recognized)

I'm losing my marbles over here. Been working on it for two whole days and can't think of anything else I can try out... If I flashed the wrong rom using CWM I might get locked out because bootloader won't be any help! :eek:

:crying: cry for help... thanks :) :fingers-crossed:
