This is the safer way to charge just a battery.. you dont need to cut any wires anymore. USB battery charger for Defy http://cgi.ebay.co.uk/BF5X-Battery-...289712?pt=PDA_Accessories&hash=item4157863df0 or just a charger for 3.99$ http://cgi.ebay.co.uk/Motorola-Defy...307?pt=LH_DefaultDomain_0&hash=item3a63866163

I have used the similar charger for xperia x1 and it really works good ! :)
[Defy General] perdar:
Wow... this stopped me from acquiring a small black motorola branded paperweight.

Thanks!
[Defy General] dedraks:
Thank you man. You saved my phone.

I was thinking it was dead.

Thank you.
[Defy General] Danhandy:
Thanks!!!!! :)
[Defy General] Sorensiim:
It still makes me happy to see this trick helping people :)
[Defy General] farsight73:
Actually one should solder a 100kohms resister between the +ve 5V and ground to make the output stable around 3.7V. A constant +ve 5V would kill things around if you're unlucky. This mod will eventually preventing any USB ports or phone to fried or explode as it run just enough power required for the phone!

I'd done this mod 5 years ago with my old motorola E398 to bypass the battery status in program mode(boot loader screen).
[Defy General] dedraks:
Thanks man. It saved my phone. :D
[Defy General] omnipotentduo:
Good call on the resistor, I was trying to figure out how much resistance to put in the circuit but I'm just not that bright, so I just went with the original instructions and on left it on for a couple of mins. Thanks again I love my defy now that its been deblured and am going to hang on to it as long as possible
[Defy General] kiedamrong:
The tip worked for me to continue with firmware upgrade, but after I got the Defy to restart and replace another battery I borrowed from my friend, it still says "invalid battery" for it to charge with, please help.
[Defy General] farsight73:
Not sure if I understand you correctly... but you seemed to have burned out your defy internal charger circuit.. a sudden high current spike might burn the board if you're not careful, even a leakage low grade battery could kill your phone.
[Defy General] zuperfly:
good morning,

my pc complains about power surge when i try this mod... any idea why?

if i get the defy in bootloader and then i plug in the macgyver cable, then it works... not yet unbricked my phone however :-)

it worked... i needed to keep the battery directly connected to a usb loader (not pc) for a while to give it a little juice...then rds recognized and i managed to flash something... now it is on... :-)

thanks
[Defy General] schossler:
My cel not show "Battery low - Cannot program" but I just got the Motorola "M" logo.

I test 3 diffrente sbf in my cel and not boot complete.

Any ideia if this work in my cel ?

Thanks, sorry my english.
[Defy General] diggernaut:
Hi, had the same issue after using clockworkmod for defy to load gapps to my defy. Thought all was lost at 3am, largely due to rsdlite not recognising the device, and all the messing around ran the battery down. Contemplated this briefly and even prepped the usb, then backed off cause I thought I shoudl wait till the morning when i had a clear head.

Well in short, on my way to bed I plugged 0% the phone into the wall (with a blackberry wall charger though - not sure if moto would work and dont have to hand to compare details), and woke up to a joyous 100% of battery. Not before i cut the usb cable though ;)
[Defy General] diggernaut:
schossler,

Prereqs:

RSD Lite 4.9

Your stock ROM (depends where you are, wher the phone came from)

Your desired ROM

Steps:

Charge phone fully

Switch phone fully off i.e. pull the battery

Boot to bootloader (Power & vol+)

USe RSDlite to flash a Stock Rom

Boot to stock recovery and wipe (Power & vol-)

Reboot

You will need to root/update to your rom as per normal process for your loaded stock ROM
[Defy General] schossler:
When I touch right corner not access the menu for wipe the system :(

The stock rom is a 2.2.1 (3.4.2-107), I will test again.

Thanks
[Defy General] Fuzorx:
im still trying to get my phone on of this crap my phone goes in bootloader mode every time i hook it into the computer but my screen still black.only when updating it says sw updating shows up when flashing. i flashed 2 diff sbf two times it say complete but still the same thing? maybe I should use rsdlite 4.9 not 5.0?
[Defy General] slyb2:
stupid question: must there be used a mini -usb cable or even an "older" one?
[Defy General] stewi21:
yeah on some ROMs touch doesnt work in recovery, press vol up + down when the green android appears and then navigate the menu with the vol buttons and pwr to enter.
[Defy General] Proda:
Works like a charm

Hey guys, this is just f*ckin awesome trick:-)

Just few notes to add here so this method could work for most of u.

First, do NOT put your battery in phone while doing this, u will just destroy it (u won't if u are really lucky, but on the other hand, are u lucky if u are reading this thread^^).

Second, if u have Voltage/Current generator at home/lab/office limit current to max 600mA so your phone can't be fried and set Voltage to 3.7V. That was crucial for me, cause phone didn't want to work with, for example 3.5V, just with 3.7V.

Then use some nice clips to connect +/- like mentioned before me...

Now u can start Bootloader and do whatever u like:-)

Good luck...
[Defy General] h9s:
Agreed it's awsome~~~

But i think best was still use the battery since it's temporarily connect to the usb , just until you can boot to boot loader and said connect usb then you plug it out and do as usual (*flash SBF).
[Defy General] h9s:
any USB will do just fine.

just make sure you didn't cross the wire in to other pin ^^

Mine phone is not powering on after RSD flash..but when i connect to PC RSD detects

Hi,, PLs help me

I installed CM7 beta6 but i didn't like it..so went for RSDlite to 2.59 stock rom... RSD lite shows PASS but my phone is not powering ON.. i thought might be corrupt *.sbf..so i downloaded it again and RSD ite is detecting the phone and flashing the device but again its not powering ON.. i think as soon as i am pluging the battery its going to flash mode..... then i reflashed the stock rom 3.4 and this time phone goes and stuck as android logo screen...pls help what to do..

i am charging my battery with wall charger to avoid low battery error
[Defy General] Dark_Plasma:
@deepaks333 Before flashing stock rom through rsdlite go to recovery and wipe data that should do the trick. To get to stock recovery power one while holding volume down. Then press volume up and down at the same time.

Sent from my lightning fast defy running CM7.....
[Defy General] arthurlage:
Man, I don´t have words to thank you!

My defy dead when I was updating and I was only getting code error.

And I was not able to flash nothing, so I discovered that i should use RSD 4.9 (I was using 4.6), bit I discovered it too late, and the battery was dead.

So I´ve made mcgyver battery and flashed UK t-mobile rom and my defy is back to life again!

But i´m having a problem on the touch screen. it´s not working.

but this is another problem.

thank you a lot man!
[Defy General] vikrambharadwaj:
have you ever heard about "factory cable"?

Its a USb cable which when connected to device will boot the phone even if the battery is completely dead.
[Defy General] kashavsehra:
Yes, thats what I was referring to previously in this thread. I believe its just a standard usb cable but with the ID pin shorted to the 5v usb pin. At least thats what it was on previous moto phones, they might have adopted the same protocol for the defy too!
[Defy General] omneon:
thanks.. it's work! :D
[Defy General] RELLdot:
wish i read that. i just ruined my droid 2 phone battery. my phone wont charge it/ recognize it. lol but i saved my droid 2 so thanks alot eveyone!!!!
[Defy General] gendo_12:
Worked

In my case i used my motherboards usb for 3 minutes checking for power surges and baterry tempetures , afterwards i was able to flash using rsdlite without any problem.

In my case it was a completly drain battery. After another 5 minutes of flashing when the phone finally boot it reported still a low but bootable level of baterry.

After around 4 minutes of used the battery drain again , i am currently using the motorola charger so that i can now root it and install cm7
[Defy General] deepaks333:
Thanks Dark_Plasma,

I had given the Defy to Service Center.( I did not told them about custom ROM) my phone was not powering ON at all..but strange thing was it was getting detected in RSD lite...just checked with Service center guy he said they tried flashing but it is still not powering ON ..they have ordered the mother board to replace..hopefully bootloader or inbuilt ROM will be part of the mother board..so issue should be solved after replacing the mother board..

I think the issue with me was i flashed UK official Froyo rom and then CM7..and after that i flashed it with Eclair India stock rom... may be its not backward compatible which was not allowing to complete the eclair flash and phone was not coming out of the boot loader... because whenever i remove the battery and plug it back and connect to laptop (RSDlite) it was getting detected
[Defy General] trinacre:
+1

thanks for trick, work fine :)
[Defy General] dab512:
This is a best way! Аnd it real safe for phone. Thanx
[Defy General] kingme__hu:
Good job!!Just have a try!
[Defy General] :
please, update the first post, that image is confusing because people think they have to put the battery on when doing this process, i did it and now my phone won't recognise the battery after flashing nordic :) ....

any solutions?
[Defy General] dev0buzz:

[Defy General] CanallaManiaco:
I love you guys. This howto saved my defy.
[Defy General] Kursage:
I was just wandering if I can use any USB cable?
[Defy General] ofmb:
yes, usb by definition carries 5 volts.

[Defy General] baddestpoet:
Hey guys, first post here for me :D

I've got a similar problem as many people here do: My Defy doesn't turn on whatsoever, no Bootloop, no Bootloader, no Recovery Boot anymore. The only recognizable vital sign is the white led when I connect the phone to my computer.

Initially I flashed the Cyanogenmod7 but that lagged quite a bit and I forgot the market and gapps as well. So my plan was to go back to the StockROM and do it all over again with a different launcher and such. I managed to install the ROM Manager and System Recovery, booted in recovery mode, wiped the phone but only got stuck in the Bootloop after that :/ So I read a bit and used RSDLite to flash the JRDNEM_U3_2.51.1 and after that the JRDNEM_U3_2.21.0 ROMs from

and-developers.com/sbf:defy

. Process succesful, status passed but no reboot, the phone would turn off and never on again :( Until today my phone still showed up in RSDLite when I plugged in the usb cord but even that is not the case anymore.

I didn't realize that you can't downgrade (why is that, I thought all memory would be erased if I do a factory reset!?) and maybe my battery wasn't full to the fullest when I tried to flash :S

So I took the MacGyver method for my last resort, did exactly as Sorensiim described it but to no effect, everything's just as before, the white led would be lit when I connect the phone to my PC but no other reaction whatsoever. I even tried to put the modded power cable directly to the battery without the phone but that didn't help either :(

Does anyone have a clue what's going on or what else I could try? It seems that charging the battery manually worked for everyone else with my symptoms. Or can anybody at least explain what happened to the battery so that it needs the manual treatment now? I got some hope left because the white led still shows up, there's got to be a way...

edit: I tried the MacGyver method several times again without any success so I went to an electronics store where they had some kind of universal charging device and put my battery in there for about an hour. The phone wouldn't respond to anything after that, too, but when I connected it to my PC again it showed up in RSDLite, what a relief! I looked for the latest ROMs to make sure I flash one that's newer than the Cyanogenmod I had before and applied it and got stuck in the booting process again. But at least I was able to get into the Recovery Boot again, do a factory reset and flash again. And it worked! Now I've got a better-than-new system that's fast, sleek and up-to-date.
[Defy General] nanodroid84:
You are a goooooooooooodddddd!!! THX!!!
[Defy General] multiplash:
Thank you very much! :)

I charged for 5 minutes, because the battery was dead, and right now I'm flashing a new sbf again :)

Many thanks
[Defy General] deejaylobo:
Can I ask, if there is a white LED light on when I connect to a charger. Does it mean my battery is charging? Because this is what I see right now. Although, it has no effect on the Battery Low message.

I'm not sure how this method will inform my phone that the battery has charge.
[Defy General] sachhi:
Same here... Very very thx for info dude.. Initially i was in wajkUI based on miui, usb tethering not working so i flashed with indian froyo rom.. Its gone, it was paused at android logo.. So i again flashed with indian eclair rom it took me too worse, phone not started also..

Now pls tel me which rom to flash so that i get phone back.. And another question How u back to recovery boot after doing all these?
[Defy General] deejaylobo:
Thank you so much, OP. This worked for me.:D
[Defy General] wpbr:
Worked for me, just with one change, 5VDC from the usb computer, has only 500mAh, and this is not enough for my DEFY, so I used the wall AC adaptor (came with defy), this one has 5.1VDC with 850mAh and worked on the first try.
[Defy General] fanis86:
I have try also this! I have try with rsd lite 4.9 and i have flash olmost any froyo rom that exist bat nothing. Bootloader says battery it's ok bat when i try to flash the rom at the phone reboot part of proceed the phon reboot at "m" and doesn't start. And continue to reboot all time. Please help!!!! Is my phone broke?
[Defy General] wpbr:
No, Ur phone is not broken, only, I don't know why, stay at the "M" logo screen, but for me, happens the same, I flashed the froyo, RSD Lite, says OK, but when boot, "M" logo again, so I've tryed plug the wires, form the usb cable, directly to battery terminals, don't work, and last, with the same cabe, just this time, connected to the wall AC adaptor, and works, but... be very carefull, don't let the wires touches nothing but the right battery terminals, and manage to place all back on the phone, so the voltage from usb/AC adaptor, goes directly to the phone and the battery.
[Defy General] amritmachoman:
i have tried about 5 times this mcgavy method but nothing happens ....still the white led with blank screen...i flashed a sbf file after rsd lite says pass and finished it never rebooted ..what to do..its my friend's mobile ..i'm extremely worried plz someone give me solution as soon as possible..otherwise i'll be in a great trouble..thank u guys!
[Defy General] evilc:
Thank you! Worked great for me today!

FYI the leads on the mini-usb cable I used were red and white not red and black, but the red was still the positive.
[Defy General] overclockthesun:
Woohoo!!!!!!! :):):):):):):):):):):):):):):):):):)

I thought I had lost my phone for sure... actually considered trying this in the morning...but could not sleep thinking about my brand new Defy being bricked. So its 1 am and I am up and awake........ tried this method :) and it works!

Lucky me I kept my old Hp deskjet cable as a spare.... it came in handy:cool:

Here are 2 pics from the thread over at modmymobile ... this will help anyone else who has a doubt as to how to connect the wires and to which part of the phone.

thank you .. whoever you are who came up with this idea... I owe you a beer! heck make that 2 :)
[Defy General] overclockthesun:
dude you need to charge the phone first...it happened to me too .. switch it off after the macgyver procedure and let it charge till at least 20% ... then it will boot normally
[Defy General] Ketres:
Congratulation, GJ !
[Defy General] kyle77680:
its very interesting bu also dangerous :(
[Defy General] sprtrainer:
lifesaver lol

this saved my week old defy after i got cynogen 7 mod reboot which ran down my battery and let me return to stock and let me try again which is now working lol
[Defy General] joydeep1985:
in my case its showing battery low cannot program but somehow if i press power button ..... it shows the motorola logo (i am on barebones rom)... showes the android animation adn then turn off again.... would it boot if i use the wall charger to charge it ? or i have to apply mcgavers process to charge it ? :( and if i charge do i need a micro usb cable to cut or normal usb cables which are used in external HDDs ?? :(

Edit : okay it boooted Phew !!!!!!!! after charging after 1 hr ... seemed like it jus needed charge ... i was scared and freaked out :( after seeing tht battery cannot program jus charged with usb cable itself
[Defy General] the2rrell:
Life Savors, this **** worked like a charm.

am back to loading CM7 thanks yall.
[Defy General] lehoaian:
Hi,

Some one please help me.

My XT720 was dead a few days, my PC can not recognize it.

When i press the power it's say : Code corrupt, Battery low, can't start ...

Then i plug the usb cable into phone, it's still msg : Code Corrupt a few seconds, after that, start boot and load to OS.

But, have a question mark on the battery icon, and my PC can not recognize phone, have tried 2 laptops and 1 PC, it's still nothing changed ! The Lock/Unlock button not works ...

I think it's using power from laptop to boot up, because when not plugin the usb cable, it's can't start up.

Please help me resolve it :(
[Defy General] mohamed.qadiqadi:
Not working

I did exactly as mentioned, but its not working. I am suspicious the screen broke or sth. Helppp!!
[Defy General] mihaidenis:
Today i make a mistake and accidentally delete boot

(i had miui )

battery was 5%

so it die

then i see this on forum

i have only one usb cable

so i search and find a useless printer cable

then i cut the head witch lead to printer

it has 4 wires

i put the wires as in the foto

Red goes to the + terminal, Black goes to the - terminal

and voila flashed again

so any cable is good as long

it has male usb on one head

hope others help.
[Defy General] brandms:

[Defy General] shgu0132:
I was able to charge and flash my defy even though the screen was blank. Thanks a lot!!!
[Defy General] nosit1:
Had to use this last night, amazing results. Great tip!
[Defy General] chinbold:
Hey, thanks for the tip.

I am gonna try the universal charger to charge the defy battery and once it has enough battery will flash it on rsdlite. I think it same as this. Seems like defy never charge the battery on recovery mode.
[Defy General] Studio1b:
good work to the poster of this
[Defy General] Tyler83:
Just a quick question. After reading this topic and the original topic linked in the OP, it's still not really clear to me if the cable has to be plugged to the battery or to the phone pins. Can anyone explain me the correct procedure? tx
[Defy General] lolzas:
Tyler83 - It should be plugged into the battery pins (there are 4 of them in the back)

what happens if my battery is just fine and I still do it? nothing?
[Defy General] dilfatx:
When I went to plug in the usb from the hack onto the laptop..i get this message

The only options i get is to reset the usb or to close it..

The light on the phone doesn't turn on.. but if i unplug the usb from the hack and plug in the regular usb onto the phone's regular port then the white light does come on..

Any solutions?
[Defy General] sd_shadow:

Motorola Battery Question Mark
[Defy General] dilfatx:
Does it matter if I use a usb cable from mini usb or micro usb? I have been told they carry same output.
[Defy General] visualist6x6:
It works!

Thank you to all who have posted this useful info!

I hooked up my battery to my modified cable and plugged the cable into the AC adapter. It charged the battery enough so I could re-flash. 2 quick items: 1) check with a VOM to make sure you are connecting the correct wires and with the proper polarity. 2) connect the wires only to the battery. That way, if anything goes wrong, you'll only lose a battery. I hooked up the cable to an AC adapter because I didn't want to risk losing my usb on my laptop.
[Defy General] TheYama:
Hi all,

I have the same problem. But I have for my lucky second battery - full charged ;)

The lesson that it is better to fully charge the battery, before we try to flash Defy ;)
[Defy General] ejstubbs:
The voltage on the power pins is the same regardless of whether it's USB, mini-USB or micro-USB. Think about it for a minute: it comes out of a USB port on your PC and goes along a plan ol' bit of wire to a micro-USB port on your Defy. It's going to be the same voltage.

Yes: don't use the USB port on your laptop. There is a limit to the current they can provide and they will shut down if the device connected to them tries to draw too much. In the case of the hack, there's no control being exercised over the current draw and if your battery is flat (which is why you're having to do this after all) then it can very likely pull more current than the laptop wants to supply through its USB port. You might have more success plugging your hack cable in to a powered USB hub, if you have one.
[Defy General] dilfatx:
Thanks for the response. As far as the battery I found a friend with a defy and used their battery and my defy still didn't turn on.

I will try plugging mine with my battery into wall instead if laptop and hope it works

:-)
[Defy General] dilfatx:
Also is it possible if someone can post a picture of the connections and the battery. I would like to ensure I'm doing this correctly.
[Defy General] tallmantim:
Managed to get it working, installed an SBF, but now phone is fully bricked - completely dead. Will not turn on with battery or with USB power connectors.
[Defy General] dilfatx:
OK i just did the usb hack and plugged it in the wall instead of laptop.. no light came on and if i press the power button the white light flashes once then turns off.

I then plugged it into the laptop usb and saw that the laptop for first time since this no battery issue recognized the Defy.. it said looking for drivers and then a pop up message came up which said "Motorola Defy ready for Flash". I got excited and loaded up RSD lite and the sbf.. only to be dissapointed because it couldn't recognize the phone.. I noticed that the laptop had lost connection with the phone once again..
[Defy General] m11kkaa:
Today it was the first time I got the "battery low"-message and your trick was very helpful. Within 15minutes my defy was working like before.

THANK YOU VERY MUCH!!!
[Defy General] dilfatx:
I still can't get this to work..

Also I have noticed that when I looked in the computer device manager I can see that the defy is plugged in with its Moto usb drivedrs and a message that says Motorola flash interface.. there are no options other than uninstall the motorola flash interface..

its been days and i keep trying this with no luck..I feel I'm doing something wrong as so many people have benefited from this..

please help
