Hello,
I am quite new to the forum although I have some experience in modding my mobile, so I hope I am posting in the right section.
I had ICS on my XT910, then I installed BMM on my XT910 and a ROM named "Muscle China" that brought along a JB China kernel (which allows flawless phone call recording), a new radio and very interesting features with Andoird 4.1.2 version.
While updating an installation on Slot2 I deleted the "system" partition on Slot1 by mistake.
I was in a hurry and I needed to have my phone functioning ASAP. So I used a method to "unbrick" the RAZR that worked but installed the stock 982.124.14.XT910.Retail.en.EU
Now it seems that this JB EU is locked and does not allow you to install other "unlocked" kernels.
In fact when I tried to reinstall the JB China kernel and I enter in AP Fastboot, I connect the RAZR to the PC and I input:
fastboot flash boot boot.img
what I get is:
writing 'boot'...
(bootloader) Preflash validation failure
FAILED (remote:... )
finished. total time: 0.613s
My system info are:
System version: 982.124.14.XT910.Retail.en.EU
Base band: U_04.10.00R
Webtop version: wt-3.0.0
Kernel: 3.0.8-g7198280 [email protected] #1 SMP PREEMPT Thu Feb 28 01:30:46 CST 2013

Can someone advise me something to do or give a help in order to substitute this kernel with another one?
Thanks!
The CG version of your device has changed. You cannot flash any older(lower CG) kernel or ROM. That is also the reason you cannot downgrade once you flashed an update.

Thank you for your reply.
Is there any way to "trick" the device and make it believe I am flashing a newer kernel or ROM?

No there isn't. Though you can flash any kexec ROM and then jbx kernel. Other than that nothing can be done.

Hello,
I just rooted and configured a new Rezound however it will not allow me onto the Mobile Network. The option itself is greyed out and I have no service? Is there any radios available to flash?
What method did you use to root? Did you flash a ROM as well? Which build number/baseband are you running (settings->about Phone->Software information->More)
I used the HTCDEV bootloader unlocker, followed by flashing the modified recovery and then Ziggy's kernel. I followed the guide here, step by step:

Sounds like a problem with the kernel you flashed. I'd make sure to do an MD5 comparison on Ziggy's Kernel and flash the kernel again. If that doesn't work flash the stock kernel again.
EDIT: to return to stock kernel check this thread.
Did you put the back cover back on?

Yeah that cover thing got me. I felt pretty slow lol
Sent from my ADR6425LVW using XDA App
It could have been a mixture of both the cover being off and the Kernel not working.
However, after re-flashing the kernel specifically downloaded from Ziggy's thread and replacing the back of the phone, the service was restored and I became a happy camper.
Thanks for the advice, base0x02!
I know this error has been mentioned before but I cant find anything to fix it on ICS they all link to Gingerbread only kernels and none of those will let my phone boot up. I have tried the two Kernels from SebastionFM (1.10 and 1.20) but neither have fixed my problem with the wifi not working. I either get Wifi error and it never turns on or it comes on but I dont see any networks. If the wifi never turns on I cant see the mac address it gives me unknown. If it will at least turn on it does show the mac address.

Is the back cover on?
I know that is stupid obvious, but this has helped a few people.
yes back on or off makes no difference.
I am running clean 4.2 and am not having that issue.
I did have it on another rom and re-flashing it and a kernel fixed me.

Which kernel did you flash? The way I understand it its all in the kernel. I am going to flash another rom to see if I can get that kernel to update.

I guess I will RUU back to stock stock and take off s-on etc and if it doesnt work send it back to get replaced.
I'm trying to root+cwm my brother's sgs2 to bring it back to life (so much lagg).
I've done this with my sgs3 but it's tedious trying to find the right method and files for this particular device.
I have searched these forums but am not reassured that I'm going about this the right way to get the rooting process over and done with as there doesnt seem to be much info on rooting 4.1.2. Better to be safe and ask than to be sorry...

This thread says I have to look under kernel version for something similar to 2.6.35.7-I9100XXKG1-CL349526 but this info seems to have been moved from kernel version with 4.1.2.
I'm guessing that i should use CF-Root-SGS2_XW_OJV_KF1-v4.0-CWM4.zip based on my CSC but don't see anywhere in this thread if I can use this rooting method for 4.1.2.
This thread also asks you to look at kernel code similar to XWLPX-NEE but this does not exist under kernel version on my phone. Now I'm not sure if I should use XWLSD (bootloop fixed) or XXLS8-FOP (Jellybean) as both of these are relevant to my device info.
Or should i use this method and run superoneclick later?
Any clarification would be thanked and appreciated!

use a custom kernel (eg siyah,dorimanx...etc)that comes pro-rooted and CWM installed.
link for dorimanx kernel http://forum.xda-developers.com/showthread.php?t=1617219
link for siyah kernel http://forum.xda-developers.com/showthread.php?t=1555259
download the TAR version of the kernel and flash it with odin 3.07.
how to use odin:
download odin http://d-h.st/SdH
boot your phone in download mode (Press and hold the Volume Down key, Home button (middle key), and Power button simultaneously. A warning message will appear on the next screen. Press the Volume Up key to continue).
open odin,click on PDA,choose your downloaded kernel,and start flashing.
hope it helps.
No problem asking, but its not that there isnt much info about rooting, its that there is far too much.
My answer depends on exactly what you want, with a view to present and future desires.
If you want root and cwm you can flash apollo/siyah or philz kernel.You can do it by odin, or see what signed zips are available to use stock recovery.
You should also run a kernel cleaning script.
So what you're saying is kernel version, csc etc. all dont matter as long as its simply an i9100 running 4.1.2 when using the above siyah/dorimanx/phillz methods?
I intend to keep it as stock as possible (my bro's terrified of rooting) until he sees its safe and wants features only available in other roms at which point i'll probably use cyanogenmod with no custom kernels.
My question (how to root when on 4.1.2 for my particular hardware) is probably what most new rooters for the i9100 come to this section of the forum for today. But unfortunately the stickies give you the idea 'do not use this method unless made for your exact device!!'
or maybe its just me...
i think i'll go the philz route for pure stock experience. i have trouble figuring out which version i need based on what my about page says:
XWLSD (bootloop fixed)
or
XXLS8-FOP (Jellybean)
??

Wow i don't know what you guys are talking about
But if you just need to root your device why don't you try
https://forum.xda-developers.com/showthread.php?t=2130276
1-klick and root
And if you need to install cwm you just have to download rom manager from playstore - he will automatically install the latest cwm for your device

No. Do not use Rom Manager on the I9100/T/G/M/P. At all. Ever. It will break recovery/cause bootloops eventually, which will require an wipe and/or an Odin flash to recover.
Besides, any recovery flashed on its own on this phone will only persist until the next reboot anyway, due to recovery being baked into the kernel/not on a separate partition like many other devices.
Flash a custom kernel of your choice = rooted phone + CWM & you can then flash whatever custom rom/kernel you want from there. No need to flash CWM separately.

Didn't know it shouldn't be used on these models, only tested it with my phone.
however how do i know which model he is using? I'm a bit confused know
Nevertheless, sry for giving false information, never would have thought it could break the phone cause it says in rom manager it will find the fitting cwm ...:screwy:
Sent from my GT-i9100 using xda app-developers app
All good Yeah, Rom Manager breaks stuff. You might get away with using it for a while (maybe even a long while), but in most cases it do the things I mentioned sooner or later. CWM has everything you need anyway.
How do you know what model someone is using ? Ask them.

Well this didn't go at all as I'd hoped even if it could be worse:
-rooted using Philz XWLSD (fixed for bootloop) and confirmed supersu was working
-made a nandroid backup in philz
-did a data wipe>clean for new rom as planning to install cm 10.1.3
-wiped cache & dalvik cache
-realized i should probably make a 'clean' stock version first to give my bro the option of choosing stock or cm
-restored the nandroid and rebooted
Now I'm stuck at the samsung logo on boot. Not sure how to go forward as this is my first boot issue ever after flashing 50+ roms on the s3 using cwm.
Installing cm thereafter resulted in no issues but it'd be nice to know i could go back to stock if my bro wanted

Well i don't really see a reason why the restore didn't work. I would try to make a complete wipe after restoring and than run the backup again...sometimes that helps ...
If no try to flash a custom rom first with the same Android version like ur stock rom and afterwards try to restore ....
It sounds not very logical but i had to do that often :banghead:

Apparently the problem was that philz does not backup the /preload/ partition by default which results in the bootloop. The only possibility is flashing the original fw via odin and trying to integrate that /preload/ partition with my current (incomplete) nandroid. Will need some time to test this as my brother is currently quite happy with cm.
Yeah.....I've run into that preload issue with PhilZ myself........
There is a thread on here by Chainfire for one of his creations called mobile Odin.....it allows you to flash a firmware 'in phone' without the use of a PC or PC based Odin.......
With regards to integrating two partial backups.....I'd be surprised if that worked.....integration IS probably possible..... But then you have to modify the MD5 file in order for the recovery to accept and flash the integrated backup.....from what I understand, the MD5 acts *like* a numerical 'bar code'.......
In the same way that a bar code is linked to a specific product, the MD5 is linked to a specific backup or other flashable zip.....I believe it 'encodes' the size, number of folders/files etc......if the MD5 info is a mismatch to the zip, cwm 'scratches it's head' and refuses to flash it........

im guessing the kernel for stock jb or cooked update?
was going to try kies update and gain root access after, but after flashing new modem kies wont accept the version for the update. thank you in advance.
Forget Kies, it's a nightmare. The rom you linked to (mr-cooks') comes packaged with the correct kernel: AJK no-swap. I believe that's the only kernel you can use on that rom.
You're already rooted and running a safe ICS kernel (the old siyah)... just download the rom and install it per the instructions in the OP of that rom.

And how to unlock bootloader?

Well, unlock boooader is not possible on this device. If you already flashed JB.xml via RSD Lite were isn't any downgrade sollution to ICS. You can flash Custom ROM via BMM without problems. Your ROM still can be JB, no need of downgrade to ICS. These ROMs seems to be so far stable for me.

I flashed and rooted Jelly Bean on my droid razr, that came with ICS, using DROID_RAZR_Utility_Jellybean_XT912_WinMacLin.zip.

If not, could you recommend JB custom roms with a good 4g radio? My phone is my only source of my internet.

There's only one custom kernel,JBX, available for RAZRs (AFAIK), and it is not compatible with stock ROM. You need a kexec based ROM for JBX kernel.
The latest configuration at present is KitKat ROM+JBX.

Plain answer, No, you Cannot downgrade. As for the custom ROMs, they've been working very good with LTE. You can try the CM 10.2.1 stable if you want to stick with JB.
