I am a noob here and a bit afraid of doing smth wrong. I want to flash a custom rom on my Lumnia 710. Can I make a backup of the partitions with windows (not ubuntu) in case I brick my device? If yes how?
Should I do the backup before downgrading my bootloader to qualcomm or before flashing the cutom rom?
Thanks in advance!

Hello folks,
first of all, i'm new to wp7 flashing and i need your help pls!
I want to flash this GREAT Rainbow Mod custom rom to my Lumia 800.
Yes, i'm one of the lucky ones and have a qualcomm bootloader!
What I've done so far:
I installed qualcomm drivers correctly using this thread: [GUIDE] How to install Qualcomm PC Drivers (if you are having installation trouble)
I read this thread and downloaded all files: [Custom ROM] RainbowMod for Lumia 800
I read this thread: Quick Flash/Debrand/Unlock of Lumia 800 - Working also on Lumia 710
Some informations about my system + phone:
- Windows 7 home 64-bit with qualcomm drivers installed
- German T-Mobile branded Lumia 800 with qualcomm bootloader
Here are my questions: (i hope u can hlp me)
1. rainbow mod is based on chinese fw, do i only have to flash the rainbow-mod-files or do i have to download the whole fw with navifirm and flash the "normal" fw first before i can flash the custom rom?
Right now my phone is german, t-mobile branded. can i simply "overwrite" this fw with the single rainbow mod "os-new.nb" ?
2. can i flash it using NSS Pro 0.48 or do i have to use "dd" in Ubuntu?
3. It says that before flashing, i have to flash a file to sdb3 partition. Can i do this with NSS Pro, too?
4. IF i would need to go back to my original german t-mobile branded fw, would it be the right procedure, to make a complete backup (with zune?) right now, so i would only need to flash back the original fw (downloaded with navifirm) that i can restore the backup?
Thanks guys!!
EDIT:
Yes, i did it! AWESOME Custom Rom!! THANK YOU lucifer3006!!
1. put phone into "Qualcomm Mode" by pressing VOL UP + POWER
2. checked with
Code:
sudo fdisk -l
how my phone appears in ubuntu
3. I made backups from every single partition using this:
Code:
sudo dd if=/dev/sdb1 of=/media/Data/backup1.bin
up to
sudo dd if=/dev/sdb9 of=/media/Data/backup9.bin
4.flashed "amssadsp.img_part3" onto sdb3 using
Code:
sudo dd if=./amssadsp.img_part3 of=/dev/sdb3
5. flashed RainbowMod "os-new.nb" onto sdb9 using
Code:
sudo dd if=./os-new.nb of=/dev/sdb9
6. installed german language using "WP7 Update Cab Sender"
Wow, this is an absolutely awesome rom!! thank you so much!!
i hope u can help me with this problem:
How can i add my Windows-Live-ID?
I already deleted the following registry key:
Code:
[HKEY_LOCAL_MACHINE\Software\Microsoft\GwpCPC]
"ActivationCode"="*****-*****-*****-*****-*****"
But how do i use "dppimplant" and where can i get it?
Or do i have to do anything else that i can add my windows-live-id ?
EDIT:
OK, i did it. I simply followed this post from ultrashot: How-To-Use-DppImplant
Worked like a charm... THANK YOU!!!
Hi there,
just another quick question:
Generally, WP7 seems to be very save, when you think about viruses & malware.
But now my phone's unlocked, is it still "protected" ?
cheers
Hi. I am new to Xperia Live with Walkman and I have some questions.
1. If I root my phone, then is there a way to unroot it and restore warranty?
2. Here http://forum.xda-developers.com/showthread.php?t=1695603
Unlocking bootloader lets you install custom kernels and ROMs. If you do it via official way, you lose your guarantee and your DRM keys, that means you will not be able to use TrackID and some other little features. If you patch it via unofficial way (test point method) you lose nothing. Anyway, if you don't intend to change your ROM, don't unlock it

So, what are official and unofficial ways? And don't I have to root phone to unlock bootloader first? Or I have to unlock bootloader to root?
OK, I've read about all of them and quite understanded it.
3. Could someone give me quadrant (may be standard, but the newest one) score from fast rom for my Live?
4. To get into recovery I have to flash it first or it have it installed already as it is in some samsungs? And do I understand well that to flash recovery (or use it to install rom) I have to unlock bootloader?
5. If I flash unofficial rom (first unlock bootloader etc) and want to get back to stock one and locked loader and have warranty back, then what should I do. Is there a way to do this?
Ok, I've read about some stuff. Now I know that I unlock bootloader and flash a kernel with a recovery. But how can I get official, signed, stock rom and how to install it?
And before flashing custom rom do I have to set partitions, as it was with HD2? Like /system /cache /data etc...

Partitions are already there, ROMs only affect /system(few also /data), /cache and /data must be formatted if you install another ROM.
Official, signed, stock ROM can be downloaded via Update Service and PC Companion. You can create a Flashtool .ftf file, there is some information on the information about it.
So I can flash custom rom and there will be possibility to get back to stock one? And what is this flashtool?
Ehhh, I need to read more
I have a tft file with a stock rom, but is there a difference between branded software and unbranded? I use Tmobile PL so when I will flash any other stock roms will they accept warranty? And when is recovery being removed? When flashing stock rom?
And could you please tell me more about creating tft (I haven't found any info about it on Xperia Live)
OK, I've found out how to make ftf. But does it restore warranty? And what with these differences between branded and unbranded?
OK, I'm such an idiot I've just looked into Tutorials | Firmware | FAQ and found that http://forum.xda-developers.com/showthread.php?t=1568792

Hi all,
I'm trying to understand how a mobile rom is partitioned and using adb and fastboot i have understood this:
There are 3 partition
-recovery (where work CWM or other recovery software)
I can flash a recovery software via fastboot, righ?
-boot :
I"m not sure of this, but should be the partition of the kenerl? Pls correct me if i am wrong
-other partition:
For system apk ?
This is what i think, pls help me to understand better my rom partitions
After this:
- if i flash i kenerl i modify boot partition (i'm pretty sure of this)
- if i flash a recovery , modify recovery obviously
- if i flash a rom what really modify? Q.Q
Ok last noon question..
How to do a nandroid backup?
it's enough the CWM backup
Or is a backup from adb?
And from adb how to backup ?
It'd enough
"./adb shell backup " ?
How someone have a bit of time to answer to me
Thank u all
Yes, boot is the kernel... When you install a ROM, you modify your /system partition. To make a nandroid backup just use cwm.

I want to make a system backup but my bootloader is locked. :/
Is this the right guide?
https://www.technipages.com/how-to-backup-your-entire-android-device
Does minimal adb suffice or do I really need the whole Android SDK?
Moreover, is TWRP still the best *rootless* way to backup nowadays?
Hi Guys,
I wanted to backup my TA partition on my z5c so I donwgraded using an Australian Stock ROM found in a step by step tutorial (32.0.A.6.200_R4B). So far so good, backup worked with ivoryroot. After unlocking the bootloader I wanted to flash twrp on the recovery partition. I porbably was not concentrated so I typed "fastboot flash boot ...." instead of "fastboot flash recovery .....". Is there anything to do about it or did I hard brick my device? Perhaps I could generate a boot.img out of the ftf file? but if yes how? Thanks for suggestions in advance.
Cheers

Edit: I managed to reflash the whole rom (which did not work yesterday) an got it to work - sorry for bothering you!
