[Q] Should I downgrade to have access to a root method? - Droid RAZR M Q&A, Help & Troubleshooting

Hello. I'm on the new system version 98.18.94 and I was curious if you guys think I should use the droid razr m utility to downgrade to an earlier version so I can root it. Is it suggested that I do that or should I wait for a root method for my current version?

There is no DG.
See my stickys about ...94 or ...1

Yes there is. I have downgraded using the utility before. It deletes everything but I have a backup on my SD card

Using the first option, it downgrades it to stock jellybean

Using the utility before doesn't mean you can use it now. On this latest OTA (and I think the one before), they got rid of the ability to downgrade. There are many people that have tried to downgrade and they get a fastboot fail, but since you're the ONLY one that seems to have this magical ability, go ahead and try it. :good:

That utility is for 2 OTAs ago. If you use it on .94, you risk a brick.

I've bricked my phone before while I was on this update. I used the utility to revive my phone. It worked just fine.

That utility was designed for two OTAs ago. So, if you used it, you would be on that system version if your bootloader was unlocked or you would have a soft brick and fastboot fail if your BL was locked. If you took the utility and replaced the .xml with .94 (which I've seen some people do), then that's why it would be working now. If you didn't replace the file, then I call BS because your system version is still .94.

I am as confused as you my friend

I'm not confused. If you tell us straight, then we can help a lot more.
Here's how it goes:
- Utility 1.10 was designed for 98.12.4(4.1.1) that came out early this year.
- Utility 1.20 was designed for 98.15.66 or 98.16.1(4.1.2)(I can't remember the exact version) and it had the BL unlock tool in it
There has been no updated utility for the last two OTAs because Matt didn't think it was worth it. Some guys over in the HD forum updated the HD utility to include the newest firmware, but there's been nothing like this for the M.

Okay so I have the razr m utility 1.20 and I tried downgrading with rsd lite recently which obviously didn't work. But it was stuck in ap fastboot mode so I used his utility to flash the stock 4.1.2 system, kernel, radio, etc. It worked just fine. I don't know why, I don't know how, but it worked.

Yeah, but it didn't downgrade you because you're still .94. It probably flashed the baseband (which is possible on a locked BL), which cleared the fastboot flash fail, but it obviously didn't flash the system or kernel because you're still on .94.

You fastbooted ...94 boot.img, not ...66 (or ...78) boot.img as you are locked.

I had to re-update my phone to .94 again after that whole thing

Are you positive your bootloader is not unlocked?

I think those resources would be better used finding a way to revert back to previous updates on locked bootloaders (say, the one before Moto patched the method) than to device a completely new method.
Is it possible to do this with RSD?

If you're bootloader is locked and you accept the initial 4.1.2 update, then using RSD will brick your device.
I have an idea. Could one "push an OTA" that would essentially install an "upgrade" to 4.1.1. If I knew anything about coding, that would be the direction I would head for. I'm decent at ladder logic, but don't know a darn thing about Linux or Java.

Signatures.. That's the only issue.. The packages must be signed with moto's signatures.. Only then will you be able to flash it.. Everything if you manage to do that, there is no guarantee..

Need stock kernal

I've been using yargs for about a month now and always seems to have problems with my WiFi dropping. I made a cwm backup before I flashed yargs but would hate to have to revert my phone that far back.
I'm on newest ota rooted and unlocked.

Restore just an earlier system to restore kernel.
I have not seen a stock zip but I bet arrrghhh's Q kernel thread has one.

I think you could RSD straight to the OTA without wiping data. That should work. Or you could extract the boot.img from the RSD and flash it via fastboot

Thanks for the solution but I was hoping for a flashable zip. I have yet to dabble with RSD and am sorta nooby with this stuff.

Checked out his thread here on xda and didn't see the RAZR m stock kernel.
I have a cwm backup from when I was using stock kernal. Anyway I can extract just the kernel from that?

No. But you can restore just that system. Wipe dalvik & cache, not data.
OR
Just reflash your rom. Wipe dalvik & cache, not data.

Get the full RSD XML from http://sbf.droid-developers.org
Then, open it using something like 7 zip. You should be able to find the boot.img in there.

As far as i know there is a possible root. Is it XT912, or XT902? That'd be helpful information. Also your probably ruining jellybean(4.1.2) which you can root. There is a forum explaining the root process for a razr m using motochopper.

[Q] Accept OTA on rooted custom recory?

I know someone who current has rooted and custom recovery and can't accept latest OTA.
I assume all he needs to do is flash stock recovery and he should be able to accept kitkat OTA?
Thanks in advance!
You may want to just grab the official kk update and flash the whole thing via rsd.... rsd 6.1.6.... And 4.4.2 KitKat....

He has the OTA on his device, but gets an asset failure when he tries to apply it with his custom recovery.
Are there instructions on how to apply this using the RSD method?

Just so I understand, the article talks about an SBF file? Is that the ZIP file? I looked in the zip and didn't see anything names SBF or anything...
Just boot phone to fast boot mode... Open rsd select the zip chose unpack and flash or whatever the option is and let it do its thing I'm at work so that was just the first link I found when I googled it

If you cannot get to recovery, you should consider doing more research before rooting or any other modding. How would you fix your device should you soft brick it?
Turn off your device, hold down volume up, volume down and power. The menu will come up and then select recovery.
As for kernel... On your phone go to settings and then about phone.

I suspect that recovery.img flash failed during last step of hydrogen peroxide root.
If flash failed completely, you would have older kernel used for rooting, that is flashed over recovery, after rooting recovery is flashed over older kernel.
If you can't get to recovery using instructions posted ubove, I suggest redownloading hydrogen peroxide and go through the steps again.
