Help updating xt910 from 2.3.6 to ICS - Motorola Droid RAZR

Hello,
I want to upgrade my xt910 from 2.3.6 to ICS, I found videos on youtube, threads here and on other websites too, but I know this is kinda sensitive thing to do so I need your help confirming the steps for me.
first of all this is my device information:
System Version: 65.1.40.XT910.MERetail.en.06
Model Number: XT910
Android Version: 2.3.6
Baseband Version: U_03.1C.91P
Webtop Version: WT-2.0.0-139
Kernel Version: 2.6.35.7-g8abf869 / [email protected] #1
AP Flex Version: GAS_ASIA_USASPDRRTUAE_P011 / GAS_ASIA_USASPDRRTUAE_A012
Build Number: 6.5.1-167-SPD-IRD-40
Build Date: Mon Feb 6 21:28:36 IST 2012
I already rooted the device successfully when I bought it.
So here is the steps as I read and saw:
1- Change the system version to 651.73.30.Retail.en.EU ... same as in this video (How to Unbrick/upgrade/downgrade Motorola Razr XT910 http://www.youtube.com/watch?v=Q_1-HxdzEo0&feature=plcp )
2- Update motorola razr xt910 to ics(android 4.0.3) on this link ( http://www.youtube.com/watch?v=zuRSKeMFPGc )
3- Then update to ICS 4.0.4 on this link ( http://www.youtube.com/watch?v=-TCgj5gbmf0 ) using this ROM [ROM, GSM XT910][EuropeAustraliaEMEA] Final EU ICS Fastboot Official fastboot package for Motorola RAZR
Am I doing the right steps?
Which ICS ROM is the best?
I would like to ask, as I read if I update to 4.0.4 there is no way I can go back to GingerBread, but what if I updated to 4.0.3, may I go back to Gingerbread if I didn't like it?
What are the negative points about ICS on droid razr? what stuff not working or something? Should I wait the official ROM?
Is there any custom GingerBread ROM(s)?
Thank you so much for you help.

Pls help.. even i am having the same ME version of RAZR and was thinking of upgraditng it.

please help.

[Q] Gingerbread upgrade for Version.4.1.120.ME860.ChinaRetail.en.CN

Guys,
I'm struggling to find solid information on whether it is possible to upgrade my phone to Gingerbread. Can anyone help? Below are my phone's vitals:
System version: Version.4.1.120.ME860.ChinaRetail.en.CN
Model number: MB860
Android version: 2.2.1
Baseband version: N_01.77.05P
Motorola webtop version: OSHWT_U1_4_257.14
Build number: ITFunz_2.2.1_CN_Eclipse_Beta3
Looks like you have a ROM with Chinese origin (I believe it's based on AT&T U4_1.5.2 with Chinese translation). Why don't you ask in Chinese android forums? e.g. http://bbs.mfunz.com/ and bbs.gfan.com
Unfortunately my Mandarin is not very good. I'm in Australia but my phone came from China. I was hoping someone else might have came across the same issue.
since yours is ME860, most likely it's an international Atrix phone. You can try "Fruit Cakes" in the development section: http://forum.xda-developers.com/showthread.php?t=1163009
there's a HKTW version probably you can use.

It s not possible due signature missmatch. However, you can restore a en.EU nandroid backup in a en.FR razr. This will give you a nice update, but keeping kernel.

others say it's a 651.167.19 and android vers: 2.3.6
167.20 is the leaked version, 167.19 is the latest official release.
You can flash any european software to your RAZR.
The only RAZRs with the signature mismatch problem are the brazilian ones.

How does one check for a potential signature mismatch error?

Is it the same problem as Korean XT910K and S?
So could a nandroid restore of a EU XT910 work on the XT910S & K even with a diff bootloader?

Not true, Canadian ones also can't have the en.eu ROM flashed due to the signature mismatched.
I bought my Droid Razr in Singapore. I had it rooted but after the OTA update for Gingerbread, I lost root so flashed EMEA ROM -
SV - 651.73.23.XT910.Retail.en.EU
AP flex v. - GAS_EMEA_USASPDRRTGB_P040
GAS_EMEA_USASPDRRTGB_A011
Build # - 6.5.1-73_SPU-11
- and now I'm still waiting for the ICS update but zilch. Could it be because of signature mismatched?
Appreciate your advice.
Thanks!

[Q] NonEFIGSRetail help

I need a little help here gents,
Basically I want to update my phone as I am stuck on 2.5.5 and want to be able to download ota updates and eventually ics. Here's the catch, I'm unfortunately on the infamous NonEFIGSRetail system version.
From my understanding I have to flash a different retail system version to allow updates and the like to come through.
My questions are...
1.
Which system version should I flash to?
2.
How would I go about doing this? (before my razr I owned a dhd and they seemed a hell of a lot simpler to muck around with)
3.
Lastly if I were to flash a new system version, how would I create a backup of my NonEFIGSRetail version just in case things went tits up?
Cheers
Jack

Taken from the Eternity project thread.
Ignore the OTAs to be sure to be on a stock rom, as some of the roms are leaks etc.
I flashed this:

@jackmanzan please use the search function as the nonefi had been solved here many times before...
I apologies if this has been covered before but from what I had read there wasn't a definitive answer.
Cheers for the help guys those two system versions look good.
Now can anybody answer question 2/3?
Cheers
Jack

3. If you're rooted, you can make an back up of your current Rom with CWM. But there's no need for.
Just charge your Battery till 100% before you flash with RSD.
Edit to 1: Here you got an actually Fastboot (2.3.6 / Baseband 91)
http://sbf.droid-developers.org/umt...USASPDRRTGB_HWp2b_Service1FF_fastboot.xml.zip
After you flashed this, you'll get an 15mb Update via MotoCast Software. So you'll be sure, that things're working right now :thumbup:

Downgrade to Stock to Upgrade to ICS?

Hello friends at XDA,
I'm currently own a EU Razr. I upgraded it a couple of months ago to a Gummy ICS release. It works pretty good, sans Camcorder.
But now i would like to upgrade to the oficial Moto ICS (from what i read, it'll be releasing soon).
I did make a backup using Clockwork of my stock Motorola.
Do i need to downgrade to be able to upgrade? Should I?
Can i use my nandroid backup simply my applying it via Clockwork Recovery?
This is the info on the "About":
Model Number: XT910
Android Version: 4.0.3
Baseband Version: U_03.1C.78P
Kernel Version: 1.6.35.7-g24431a2 [email protected] #1
Build Number: ICS_Beta_MR1
Apreciate any enlighted info on this :laugh:
