[how to] install froyo! {ultimate defy owners guide}

new method!! 30/5/11
download this
download
basically.....flash the nandroid from within recovery then straight into bootloader the flash .sbf via rds lite.
or not basically......
put the nandroid on ur sdcard in folders called "goapkrev" and inside that "backup"
ok you need to install clock work recovery from my ultimate defy package
then boot into clock work recovery
choose back up>then select the nandroid
wait for that to do its stuff
then pull battery out
then enter bootloader by holding volume up and power for 5 secs
then connect phone to pc
make sure you have moto drivers and rsd installed
then in rsd lite choose the "3.4.3_11-Fixed.BLUR.sbf" file and click
wait for that to finish and that should be it
if you get a boot loop enter recovery power and volume down for 5 secs you should get a black screen
then volume up and down at the same time
wipe all data
reboot!
that should be froyo!!
you can now install a custom rom ontop of that if you wish
thats from memory but i think that should work
any questions ill try to help
my old guide below
contains my ultimate defy package which has every thing you need to root, recovery and install froyo all zipped up in a nice package if you prefer to do it that way
Code:
[color="#0000FF"][size="6"][u][b]This guide will show you how to get foryo on your Motorola defy ahead of schedules!! [/b][/u][/size][/color]
use at own risk not fully tested
[color="#00FF00"][size="4"]as it stands every thing seems to be working in froyo now including wifi gps camera market led and sensors
however it is still a custom rom and i acept no responsibilty if u brick it which is very hard on this phone[/size]
[/color]
[color="#0000FF"][size="4"]First i reccomend you download my ultimate defy package it contains every thing you should need to get froyo working! (still needs testing but should work)[/size][/color]
[size="6"][url="http://www.filefactory.com/file/b577129/n/Ultimate_Defy_Package.zip"]Downlaod my ultimate defy package[/url][/size]
[color="#FF0000"][b][size="5"]Detaled method(scroll down for short method)[/size][/b][/color]
Just because you can drop it in the bath doest protect it from bricking make sure you read carefully to avoid this and if you do brick it it can usually be recovered. I accept no responsibility for what happens but i will try and help.
1. You should have already downloaded my ultimate defy package so navigate to the froyo section
2. First install moto drivers either 32 or 64 bit depending on your os version
3. Then install RSD lite
4. Then reboot pc
5. Then put either the T-Mobile US or GB update (the whole folder) on your phones sd card under goapkrev/backup
6. Power phone on into bootloader mode by holding power on and volume up for about 5 secconds
7. Then start RSD lite and in the file name section navigate to the (JDGC_U6_0.26.0_SIGNED......sbf) image inside the Chinese 2.2 folder
8. Select device from the box below and click start and give it about 5 mins until it says its done and let it reboot
9. Then use super one click to root phone (make sure usb debugging is enabled in applications>development>usb debugging (tick box))
10. Next turn usb debugging off and install the recovery apk
11. Then click on install system recovery and allow super user permissions
12. Then boot into recovery mode (navigate around using volume, power to select)
13. Clear data and cache
14. Then go to back up & restore > advanced restore and choose the GB or US update you put their earlier
15. Wait for that to finish and then pull battery out
16. When you put is back in you need to boot into bootloader mode again (volume up and power)
17. Then in the same way use RSD lite to flash the file inside the boot image folder
18. Reboot
That should be froyo!!!

Sorry so can u flash the gb. Sfb straight off and I will work. This method does work but i made the guide b4 it became available and only just got round to posting it here. This way does work but I may update it if that way works it sounds simpler

Hi!
I live in Brazil. Then, what update should I use? T-Mob or UK? Any of them will work?
And, I saw a large number of defys that had unworking/dead flash and unworking Market. On this mod, both of them works fine?
Mobile info:
Sys version: Blur_Version.6.14.5.MB525.AmericaMovil.en.BR
Version Number: 01
Model: MB525
FW version: 2.1-Update1
Version Number: JORLA_U3_6.14.5
Thx.

Is this the UK 3.4.2-117 froyo you are talking about?
or this:
2.2.1 Froyo, Build 3.4.3-3 en.GB with Blur

Thanks! I wish this is available before I flashed 2.2. It really scared me when things went wrong.

*enter bootlader mode flash TmobileUS_Boot_Devtree.sbf
i'm currently at this part. i flash it and was at 'please manually reboot your phone', but when i do it, i'm stuck in a boot loop. any idea?
i tried redoing the flash again, and even went to wipe the data again before starting the flash again, but still stuck in a boot loop.

nice how-to guide!

PLEASE HELP ME....i did everything , i followed instructions perfectly, but when it came to letting the phone reboot after flashing the sbf file it just did not reboot, now nothing is happening on my phone at all. i think it bricked please help me A.S.AP thanks

please help me, its not switching on or anything, the only sign of life is a white led when connected to computer via usb.

it is still being recognised by rsd, ive re flashed it 3 times and left to reboot but the phone just does not reboot, i realy am stuck on this one

well i have re flashed the original
JRDNEM_U3_2.51.1_BLUR_P3_SIGN_SIGNED_USAJRDNEMARAB1B8TMGB030.0R_USAJORDANTMGB_P039_A015_M003_HWp3_Service1FF.sbf
and it is back as it was before...that was a right panic attack i was having!...but any way does anyone know what could have gone wrong? because in rsd it goes up to executing 100% but it never reboots the phone.??

could it have been because my defy was rooted? or could it be because busybox wasnt installed properly? i do not know

hmmm sounds odd.
thats what happens when u have downgradability problems what version where u on b4?
i know what u mean panic attack when it wont turn on grrrrrr
but youll be happy to know as well as being hard on the outside its quite tough on the inside and very hard to brick!

yeah thank god for that hey!
i was / am running android 2.1 build U3_ 2.51.1 but it is rooted.

thats odd then. i have no idea why that happened rooting it shouldnt effect it ne way.
however this guide is outdated now and their are easyer ways to do it now
but personally i would reccomend to jump straight up to gingerbread with cm7 its totally the dogs dangalys

would it be possible for you to point me in the direction of that please? sorry i would look myself but id probly get the wrong version or something. also would it be possible instead just to download and use the nordic one in uk? would i still get internet and signal and stuff?
the nordic one from herehttp://and-developers.com/sbf:defy ? or would the orange 2.3 one work for a t-mob uk?

[Q] Bricked defy

Few days ago I moved from HTC Desire to Defy.
I did root it, installed 2ndInitRecovery. After rebooting I couldnt get defy booted from 2ndInit and ended upu bith black screen. Still dont know why but I uninstalled 2ndinit and ended up stuck on motorola logo, I still can get into bootloader thou.
When tried this solution:
http://android.modaco.com/topic/324...ering-bricked-firmware-on-your-motorola-defy/
RSDLite can see phone connected but there is no info about it (IMEI etc)
and updade doesnt start.
Anyone to help?

if you are on eclair froyo or leaked gingerbd try to set normal boot on sndinit

trouble is that I uninstaled 2ndinit recovery

if rsd can still see it and u can get into bootloader just flash a different rom onto it,i had similar and then flashed the uk 2.2 retail it came str8 back to life!(then i installed CM7...)

What version of RSD Lite are u using??
I had the same problem no IMEI or other info only N/A when i used the latest RSD Lite problem was solved.

Win 7?
I have been through the same problem and was wondering what os you were using?
I had very little success with win7 x64, I had to get virtualbox and create a win XP virtual machine to make it work.
Also, in order for RSDlite to see your phone, you have to turn the phone on while pressing the volume up button, that'll get you to the bootloader and then RSDLite will see it.
I suggest you use this SBF: JRDNEM_U3_3.4.2_179-002, it is the CEE one and I found it was the easiest SBF to allow custom rom and such (linky)
I hope that helps.
Good luck!

RSD have never seen my phone (i mean model, IMEI etc) but it still worked without any problems

Im using 5.3.1 version. The only info I got is
Bootloader version: v0x000910
Ap Die ID: 18100005cdf767010000dcff0200
Rest of details is N/A
Status: connected.

As long as the phone shows up in the device list on RSDLite and that you can put your Defy in bootloader mode, you should be good to go.
RSDLite never gave me accurate details about the phone when I had these issues but I was always able to flash SBFs.

I did manage to flash SBF and root my defy. The only problem is that I cant download anything from market.
Any suggestions?

If you try to download from a GPRS or 3G network, disable the download from wi-fi only tab from settings and data management.

Go to recovery wipe cache/data

Go on the CM7 thread. End of first post and download the latest google apps from there, reboot in custom recovery (CWM recovery or SndInit recovery) and flash the zip.
Re. your bootloop problems:
did you turn off usb debugging after installing Sndinit and did you reboot 2 times (1st boot --> normal then 2nd at blue led, volume down?) ??
If you would have followed the FAQs of CM7, you would have had no such problem....

[Q] If you help me i will TRY not to mess up with my defy again

Hi, I have been messing uo with my defy and now i don´t know if is brickes. I would need some help please.
I got my defy with android 2.1 from the retailer (vodafone). A few months ago i instaled through rsd lite a froyo rom: DEBLUR_SIGNED3.4.2-131-003. Last week i decided to update to MS2Ginger 3.0 lite and kernel i did it using 2nd init as shown in the thread . Everything worked fine until then (wonderfull rom).
I started messing with apk file and i got errors son i tried a wipe data and cache using 2nd init. But didn´t work fine it gave me errors. so idecided to reinstall 2nd init this time i think i used cm stable not latest. Then my defy started to enter to 2nd init each time i try to reboot.The SO didn´t start . so i decided to unistall bootloader from 2nd init. I managed to start the SO but after about 10 sec it rebooted again and again.
After reading some posts i tried to flash back to froyo JRDNEM_U3_3.4.2_155-002_DEBLUR_SIGN_SIGNED_UCAJRDNEMARAB1B80AA03A.0R_PDS03C_USAJRDNFRYORTCEE_P011_A010_HWp3_Service1FF throught rsd lite and i managed to do it Succesfully (only an error when the program askes to start up manually the device. I had to unplug the cable, remove the battery, then start the device in bootloader, reatach the cable and after rsd lite gives me succes)
But the phone doesn´t start it stais in the android bootanimation screen of this new froyo rom.
At this moment my phone doesn´t boot
I can get to bootloader by power Vol+
When i try to get to recover Power Vol - i get a screen with the android guy and an exclamation.
It looks i can flash an sbf throught rsd lite.
What can i do. Please help.
Should i keep trying to flash other froyo roms (i already have 2 or 3 froyo and gingerbread)
Sould i flash recovery-clockwork-2.5.0.1-sholes. to have custom recovery
I am afraid of keep messing things without trying to get help from you.
Thanks.

This was asked several times...
After flash SBF froyo (JRDNEM_U3_3.4.2_155-002_DEBLUR_SIGN_SIGNED_UCAJRDNEMARAB1B80AA03A.0R_P DS03C_USAJRDNFRYORTCEE_P011_A010_HWp3_Service1FF) you have to go to stock bootloader, not 2ndinit... You only have to press and HOLD vol - all the time during boot sequence. You will see a robot and a "!". Then, press vol+ and vol- at the same time... Use vol+ and vol- to select options and power button to "accept". Select "wipe data", select "yes", once it finish, select "wipe cache" and "yes". Then select "reboot now"... You are done!!!
PD: Next time, you should use search!!
PD: Video of how to do that (Youtube is your friend!! )

At the end of the post you can read... your problem/situation... "I downgraded from CM7 to Stock / Installed a new SBF but I'm having bootlops: (!) If this is happening to you, after flashing the Stock SBF, enter in Stock Recovery and do a full wipe (Data/Cache) and reboot."

I messed up my phone so many times... No need to be worried. It is a learning curves. You mess up...you learn...

we all do it mate, day two of having my defy I was in same situation, after that I said I would flash no more, 4 days later got the itch and it was cm7, having flashed everything that doesn't look moto since all I can say is
Search there is always someone doing the same thing,
Keep a new ish nandroid, (I refresh it once a month)
Never flash gb sbf to standard defy, there's no need,
And enjoy

Doomed Dify+ with stock ootloader???

Hi Guys,
Since I cannot yet post at Home > Motorola Defy > Defy Android Development > [JB] CM10 Android 4.1.1 for the Defy(+) i am posting here.
I was running CM9 on my Defy+.
I tried to upgrade to the 0828 JB for Defy+ and ended up with
Bootloader
09.10
Err:A5,70,00,00,23
Battery OK
OK to Program
Connect USB
Data Cable
How? I can't remember.
but every time i use the bootloader and try to load the JB file it says \:
E: failed to verify whole-file signature
So by my understanding i need a custom bootloader as before. (i can't really remember how i loaded the ICS).
Help!!!!!!!!!!!!!!
Regards.

You need to flash a full sbf now to get it back up and running. Have you ever done that?
This bootloader error is a result of flashing the wrong version, are you sure your phone is a DEFY+ and that you flashed the DEFY+ version?
Anyway, just tell us if it's DEFY+ (MB526) or DEFY (MB525) and we will tell what you need to flash to get it back up and running. I hope you do remember that

MB526 Asia Retail SBF

Its a defy+ . I downloaded the required sbf but no idea on how to install.
I got as far as Android System recovery (3e) but under apply update from sd card i can't see the .sbf file!!!
help help help !!!!

CHARGE PHONE BATTERY ABOVE 80% BEFORE PROCEEDING......
Requirements
Get the SBF you want to flash
- Full SBF: No Nandroid backup needed, always keep CG versioning in mind.
- Fixed SBF: You might need a matching Nandroid Backup.
Get and Install RSD Lite v4.9: There are reports of other versions working, but this one is what I have used.
Get and Install Motorola Drivers [32bits] [64bits]
Now to Business:To Flash full SBFs, here is the standard procedure:
Open RSD Lite: Click on [ … ] Button and select your .SBF (Remember to rename to a short name and put it on root of your PC) and click Open.
Boot your phone into Bootloader Mode (check last section if you don’t know how to do it).
Now connect your Defy to your PC
The START button on RSD Lite should be available now, click and wait.
How do I enter Recovery Mode?!: With the Phone off press VOLUME DOWN then, while still pressed, power up the phone and leave VOL key pressed until you see a Yellow triangle, once you see this you are in Recovery now press Vol Up and Vol Down at the same time (if you are in Froyo) and the menu will appear, if you are on Éclair the menu should appear without having to press anything.
How do I enter Bootloader Mode: With the Phone off press VOLUME UP, then while still pressed power up the phone. Keep the Vol key pressed until a black screen with some white letters appear. This is the Bootloader.
After Upgrading to Froyo my Defy is laggy, slow or reboots: (!) This is a common issue when coming from Eclair to Froyo. If this happens to you, just do a full wipe (Delete Data/Delete Cache on Stock Recovery), after that your phone should work correctly.​

Need - MB526 SBF - Asia Retail 1321 Multilanugage 3.2.6 - Not China!!
Thanks so much.
It worked so far as the loading of SBF is concerned (RSD Lite v5.7 - used it last time , had forgotten)
Only, now the phone will not boot. The screen remains blank/black (not a flicker). Connecting to the USB powers on the White LED. thats all.
Thankfully RSD detects the device still.
The sbf I used was:
DEFYPLUS_U3_4.5.1-134_DFP-1321_CN_SIGN_SIGNED_UCADEFYEMARAB1B50AA009.0R_PDS03C_USAJRDNGIBRIRD15_P014_A026_HWp3_Service1FF
@ http://sbf.droid-developers.org/umts_jordanplus/list.php
I need the GB 1321 Asia Retail MultiLanguage Version (2.3.6) . (I had this when I moved over to CM9)
The one mentioned above is Chinese I guess. Tried twice with it but no luck
Any possibility of getting the right one? or some SBF that will work??
Pleaseee

tried many SBFs for DEFY+. All end up with a pitch black screen . Power button does not seem to boot Android.
The power button works though as while being connected to USB and White LED on, pressing Power button disconnects the device from RSD Lite.
I am at my wits end. is my Device Bricked for all times?
Quick recap on how I reached this point.
1. Rooted the Defy+ (2.3.6 Asia Retail Multi Language)
2. Installed CM9 (was on ICS for two months)
3. in boot loader installed JB (0828). Before that the Kernel link provided alongside on CM10 instructions. Wiped cache/Dalvik.
got this:
Bootloader
09.10
Err:A5,70,00,00,23
Battery OK
OK to Program
Connect USB
Data Cable
​
4) I did something further like a factory reset (cant remember )
5) Since then the bootloader gives me : Android System recovery (3e) not the other bootloader.
6) Flashed SBFs to try get the GB up and running atleast. End up with no show on the screen.
(though the "SW Updating.." prompt comes thru RSD Liet on the defy screen, so the display is working)
Can even find the right SBF now.. please help. Am desperate for now.. no other handset

[Q] Update messed up G-Pad

I had stock installed, rooted and twrp install, I downloaded the update and now it only boots into twrp. So i tried factory reset and restoring a backup I had, still nothing. Just now I pressed advanced wipe everything except SD Card, now I have no OS And no backup to restore.
For some reason twrp doesn't recognise any micro sd card I put in, says it cant mount them.
I can't get adb working whilst in recovery. I just want to go back to stock.
Also holding down vol down and up to get into download mode doesn't work.
Thanks for any advice.

Got it into download mode now somehow (rebooting from twrp instead of cold boot) and downloading the stock firmware from LG mobile support tool.

1. Turn off the tablet. (from twrp menu )
2. Push vol+ and vol- same time.
3. Insert usb cable.
4. Release both buttons. Now you should be in download mode.

hi mike_1983, but have you solved with this method?

I was in same situation. And i solved installing stock room with LG Mobile Launcher.
Go in download mode, and then follow this method: http://forum.xda-developers.com/showthread.php?t=2471370 is 100% working.

dont update the official rom if you re rooted or you have a custom recovery, they ll brick your tablet. If you have access to recovery you can install a custom rom and there is no need to go back to full stock (unless ofc you want to keep the stock rom in which case you need to flash it using the lg mobile support tool)

I think I did it by holding down vol up and vol down whilst in twrp, then pressing reboot, system (or perhaps pressing reboot system then holding them down). I'm not sure if the usb cable was plugged in or not. I tried holding down vol up and down from powered off, but it seemed to still always go into twrp.
Then you need B2CAppSetup.exe which is LGMobile Support Tool, you can then download the stock rom, it overwrites everything, like recovery and root.

Made the same mistake : said yes when the tablet proposed me to update. Booted in TWRP.
Tried to flash with support tool but it stops at 95% and tells me in german (!) to remove the battery and try again... I've tried many times (without removing the battery obviously), just the same.
And now I can't get out of the download mode. Everytime I plug the USB cable, it goes to download mode.
Any suggestion ?
EDIT :
I even tried this method : http://forum.xda-developers.com/showthread.php?t=2622777
and it stops giving me a decompression error...
Edit 2 : it finally uncomressed corectly but i'm still stucked at 95% when installing : WPARAM_UPGRADE_ERROR
EDIT 3 :
Using the method http://forum.xda-developers.com/showthread.php?t=2622777 and leaving default parameters : Korean language and country it finaly worked with the V50010A_00.kdz firmware.
My lg g pad is finally booting ! (the battery is totally drained)
Thanks to all !

Many Tanks to Exoten (and others) :highfive:
Same mistake... Same errors (no standard flash / method available)... Try method from Edit 3 and ... My wife is happy again (this is her tablet)
++ No Wipe data necessary - All data (SD and internal were kept)
+ the OTA upgrade was applied, even if I selected A version of KDZ (and not B version)
- I lost the root
