[Q] Milestone 2 bricked. Doesn't power up

Hello I have a problem with my milestone 2.
I was using cm7 and today I flashed the official gb sbf via RSD.
Then the phone bootlooped and I tried to enter motorola recovery pressing the "x" and then the @, but when the android exclamation appears and I pressed the @ nothing happened. As I have not gotten into recovery mode I decided to flash froyo sbf.
RSD said "finished" and didn't do anything. I tried to boot up the phone via power button and nothing happens. Tried charging the phone with no results. So now I've got no idea of what to do.
Any ideas?
Sorry for my english
Thank you

Ok now ive managed the way of flashing the phone again. Weird though, With the screen in black. Now it works. For avoiding the bootloop, it is possible to wipe data/dalvik/cache via the pc?
Thanks

Are you sure you have some charge in battery yet? Did you have full battery before flashing SBF? If you are sure, this is not because battery is empty, then try to get into bootloader by holding Power+Volume Down+Camera button and it should be recognised in Windows and then you can try RSD Lite. Or you can try another computer/cable/Linux
EDIT: I don't think so, since you can only use RSDLite (or sbf_flash in Linux/Mac) when in bootloader mode. So best way for you would be flashing SBF again.

yes I had battery and I bought a wall charger just in case. ( I had the battery problem months ago)
I'm having strange issue. The screen is black and RSD recongnises the phone. I can flash sbf but the screen is block during the "creating image file" status. When rsd says "flashing code group etc..." the phone screen lits and shows "SW update in progress" as normal.
But when RSD reaches 100% it says "finished and PASS".
I've done this before and at this part the phone reboots and rsd messoges "the phone is being rebooted"...
Now im trying too flash gingerbread official again...
let's see

Ok now with the official GB sbf the phone reboots lets see if it bootloops.
Asking again!:
Is possible to wipe dalvik/data/cache without entering recovery? via PC?
OK if someone has this problem remember that the @ button doesn't work anymore. Try vol up + vol down instead!!!

My MS2 is too. Don't boot into HS.

i had same problem here`s solution.

Having the same issue, none solution worked for me so far...
have u guyz flashed that 70.13 bootloader before? i did it like 3 months and i think that's the issue.

How is it?

OK people this problem is semi-solved.
If you flashed the official GB you can't downgrade.
If you try it you will get a black screen and the only solution is to re-flash the official GB

that`s, what i wrote answering Your post

This problem can fix.
1. Enter Stock recovery by: Put both POWER + X -> put together Vol + and Vol -.
2. Factory reset ( wipe data) and wipe cache partition
3. Done...

Guys, I am having kind the same problem with my device.
I try factory reset on the recovery mode, but then the phone shuts off before it end and does not comes back out (I have to wait couple minutes to get back).
I was trying to upgrade my phone from 2.2 to 2.3.5...
I try the bootloader and it shows me that the battery is low and nothing happens.
This happens, even when it is pluged to the wall charging.
I see also that, the light next to the mini ubs connector shuts off when the phone turns on.
I do not know what is going on and what else I can do to fix it..
Can you guys help me out?

My M2 doesn't bootup afer try downgrade from GB to Froyo, i try boot up the phone via power button and nothing happens.

You can't just go back to froyo from gb, at least not directly.
If you were on any 2.3.4 or Retail/TIM Brazil 2.3.6 (not VIVO) , you can try this method: http://forum.xda-developers.com/showthread.php?t=1497263

Maybe you tried to downgrade a non-downgradeable 2.3.6 firmware... what firmware did you have before the brick?

Maybe try to flash via RSD Lite the same stock firmware you had before CM7 (GB) and do a full wipe, then if the stock firmware is downgradeable (you have to check that it is BL=3 or lower, if it is BL=4 you're stuck in GB) try the method posted by Lean946: http://forum.xda-developers.com/showthread.php?t=1497263
In the post linked there's a tool to check the BL version
To flash the original stock you must get the sbf file from here: http://sbf.droid-developers.org/umts_milestone2/list.php
And the motorola drivers from http://developer.motorola.com/tools/usb_drivers/
And RSD Lite 5.7 from http://www.mediafire.com/?racaejnadym1q2g

[Q] Need help saving a bricked Defy

Hello there,
I apologize if the thread seem redundant, but I've already tried I found the forum about similar issues to no avail.
So I bought a bricked Defy on eBay for a couple of bucks and I'm trying to revive it. The seller said he bricked it after a flash that apparently when wrong.
The phone does not power on at all and doesn't even react when the power button is pressed. The white LED turn when I plug the phone to a computer. It does not turn on when plugged to a wall charger.
By using the "MacGyver" method, I have managed to make the phone show up in RSDLite. I have tried to flash multiple SBF images with different CG versions. Each time, the phone wakes up and shows "SW UPDATE IN PROGRESS" in blocky font but dies again once the flashing process end. RSDLite simply shows PASSED. Also every informations listed by RSDLite in the "Devices Properties" is shown as N/A except for the bootloader version and the last 4 lines.
Another issue is that I'm not even sure whether it's a DEFY or a DEFY+. The seller listed it as a DEFY+, however the battery that came with it is a 1540mAh and the lens seem to be green. I've tried to flash a DEFY+ before noticing this, so hopefully it didn't screw up the phone even more.
So, any idea? I would appreciate any help provided. Thanks!

The most important thing is to use the latest version of RSD and drivers.
I have a Defy plus and the same thing happened to me before (black screen even no bootlooder) so I connected my phone to the computer (I can't really remember if I powered with a vol up or not) but I got it recognized by the RSD. try connecting and powering on the the vol up if nothing just connect and see what will happen.
In my satiation, the phone got recognized in the RSD and remained black screen till I pressed start then it finally showed SU UPDATE.
The defy plus has a grey colored power buttons and screws but the defy is totally black
The most important thing is to use the latest version of RSD and drivers
And please tell me if it worked.

Thanks for the reply. Now I know I have a DEFY!
Unfortunately, getting the phone recognised isn't the problem. I can flash SBF and everytime the process seem to go without any error (RSDLite just show passed once it's done). But the phone is still completely bricked. I also tried the "TI Flash erase" option, to no avail.
I'll just try again a bit, then I guess I'll list it back on eBay.

Did you read Zephyrot's All-in-one thread? I guess you haven't...
Zephyrot said:
CG Versions
With that explained let’s get to business with versions:
CG Version 2: SBF 2.21 / 2.34 / Chinese (Éclair) (Defy)
CG Version 3: SBF 2.51 (Éclair) (Defy)
CG Version 4: SBF 3.4.2 (Froyo) (Defy)
CG Version 5: SBF 4.5.0 / 4.5.1 (Gingerbread) (Defy)
CG Version 6: SBF 4.5.1 (Gingerbread, 2.3.6, (Red lens Defy/Defy+) )
CG Version 7: SBF 4.5.1 (Latests Gingerbreads, 2.3.6, (Red lens Defy/Defy+) )
If you try to flash a lower ID version than the one already on your phone, you will just get a Black screen after booting or a screen telling you to flash an official rom.
So, with this in mind, you can now hop between Android versions without screwing up your phone.
If you have an Éclair Defy and would like to keep the ability to downgrade to it, you should ONLY install FIXED SBFs of the Android Version you want to install, and then use the corresponding Nandroid Backup for that Fixed SBF.​

If you have flashed an SBF with a higher CG39 version than your original, there is a good chance you now own not a Defy, but a Defy+, which is not a huge issue, unless you need to get back your stock ROM for warranty purposes or if your phone has a green lense...

Well thanks for the reply, but my problem isn't that the phone fails to boot, but does simply not turn on at all. It's literally dead as a brick. I've already tried to flash pretty much every sbf under the sun (Including DEFY+ once) and the phone never turned on once (Not even the Moto logo or a bootloader error screen).
The only last thing I see might be a defective battery.

Yeah could be a battery. Get a cheap one ebay job and try a sbf then if it loads then great u can allways put cm7 or cm9 on it
defy cm7

Change your battery or charge with external charger (universal charger)
Or this may work

I am with exactly the same problem. No bootloader, and SU UPDATE showing while the process occurs, and PASS at the end. But once finished, can't turn on the phone.
I have a Defy+ ( and other Defy who helps charging battery).
Do you think I need to try MacGyver method?

Strange Bricked Defy ?

Hi all,
I have a friend's Defy from a French carrier and my friend is with another carrier so I decide to SIM unlock it by installing CM7 and other files.
So I have root it and install the recovery.
In recovery, I have flash CM7 and Gapps.
But I get a boot loop...
So I decided to flash JORDN_U3_97.21.51 SBF and restart from scratch.
But now, the phone wont boot at all.
Nothing on the screen but it's still reconized by RSD (even if nothing is displayed on the screen) I can re-flash SBF files and RSD say "PASS" but doesn't reboot the phone.
So now I have a brick and can't boot vol up + power doesn't display anything.
Dose anyone have an idea for me ?
Thank you.

1st don't loose your battery - when no working system on the device then it is not being charged
You wrote nothing about wipes - have u performed them? If not try to get into any recovery and wipe user data / factory reset, try vol- w/power or vol + & - together, take a battery for some time before doing it etc.
What ROM u had before flashing CM7?
Is it defy or defy+?
And you flashed CG5 sbf
When you give more details maybe I can propose proper solution.

If I understood right, OP's DEFY is completely bricked and he cannot even access recovery.
Anyway, I unfortunately no solution to propose as I have a DEFY in the same situtation and I'm currently unable to revive it. We aren't the only who had DEFY bricked like this and some managed to have it wake up by flashing certain sbf.
You can try searching "bricked defy" on XDA and see what sbf the topic creator used to save his DEFY, if he succeeded to.

dont flash sbf just after the bootloop..!

frend i wanna tell u onething.the very first time i did the flashing of cm7.1stable on froyo 2.2.2defy i got a bootloop..since i was in hostel i cudnt afford internet..so i was soo scared and even waited for 15 min..but the cm7 logo with an arrow swirling around didnt stop..i puld the batery out and again inserted and did something stupid like clearing data and got the condition worse
then i flashed sbf using rsd lite ..again rooted and flashed cm7.1 stable and got bootloop..this time i surfed net and found what shud hav been done ..
1)pull out the battery after the boootloop.
2)clear cache
3)reboot
tats it..the welcome window comes in no time..
so coming to the present issue, after flashing the smf did u get bootanimation with light passing over "android" againg and again ??

Defy not booting after froyo sbf flash, not going into stock recovery or bootloader

My Defy had CM7.1, running well. I tried to upgrade to CM9 after making a nandroid backup. During first boot, i was stuck at 'wizard has stopped' when i touched the android icon.
I tried to restore my nandroid backup, but phone booted into recovery.
Then i tried to flash JRDNEM_U3_3.4.2_177-005_NORDIC_SIGN_SIGNED_UCAJRDNEMARAB1B80AA03A.0R_PDS03C_USAJRDNFRYORTNORD_P003_A001_HWp3_Service1FF.sbf
through RSD lite 4.9 but probably battery was drained, as i could not get the phone to boot after pass message, just a white LED and phone not detecting on RSD lite and not going into boot loader.
With macgyver hack, my pc could recognize the phone and i have flashed a number of ROMs but phone never boots.
While rest all sbfs were froyo, i also flashed
3.4.2-179-002-tmobile-froyo-fixed.sbf
T-mobile froyo bootonly.sbf
and
Tmo_2.2.1-3.4.2-107-boot-devtree-ONLY.sbf
Please help what should i do to get my defy back? I dont have warranty cover.

after macgyver hack flash one sbf. go to stock recovery and wipe your data/chage.
Than you sould flash again one froyo. And it will work. Good luck.
I had same problem when i went back to froyo. I forgot to wipe date/chage and it didn't boot.

Hi together, well I hope this is the right place.... I'm owner of a motorola Defy MB 525 that ran without any problems on cm9 nightly for last 6 month. Now suddenly it doesn't start any moer andIi can't access recovery setup nor anything else so it's impossible to wipe anything, too. When connected to my notebook only the white LED is shining but nothing happens. The typical "hardware-found-ping" appears and several seconds later the " hardware was removed ping." The right drivers are installed on my notebook, but even RSD Lite doesn't found my Defy so I can't flash enything. Anyone has any Idea what to to?

[Q] Is My Motorola Defy Dead / Bricked

Hi. I think I bricked my phone...... All I get now is Black screen, nothing happens when I try to start the Bootloader , and also nothing happens when I try to start the hard reset (holding the volume + and power button) ... All i get is a black screen , my phone is recognized by the RTD Lite, I tried flashing stock software but I still get the same Black screen , and the thing is that I also get a white LED when i connect it to RTD Lite , after I finish my flashing ( I tried many stock softwares) the RTD says that the phone is rebooting but the screen just turns off and remains black , that's it..... I tried removing the battery and such, I have 2 batteries both of them are fully charged... I have all the drivers installed on my pc , I think that how this happened is I flashed by mistake a DEFY + stock soft... is there and hope ??
Thank you.

Looks like you're trying to flash an sbf with a bootloader version lower than the one you had. Flash the DFP 231 CEE sbf as suggested above. That should work.
Root it and flash one of the custom kernel builds. Hope this helps.
