Flashing back cm7 from cm10. Is it safe? - Atrix 4G Q&A, Help & Troubleshooting

So I've been reading through the forums in search of this answer but I've been unable to find a definite one. I want to try epinters cm10 but if I don't like it, is it safe to flash back neutrinos cm7 using CWM recovery? Will I brick my phone by doing this?
Thanks!

The answer to your question is yes. But the best way to return is by restoring the nandroid backup you will create before trying CM10 (or any other ROM). No brick fears unless you try to flash an sbf (which you should never do).

Thank you so much for the quick response.
Before I flashed cm7, I made a back up of my stock. Same applies if I wanted to flash back to stock using the nandroid backup, correct? Sorry, I just want to clarify completely before doing anything.
Thanks again!

You only have to backup your current rom if you think you might want to go back.
Always backup before installing new roms, or making any major changes, or even when you have your current rom set up perfectly. Using rom manager makes it easier because you can name them whatever you want. You can never have too many backups!

Awesome man. Thanks for all the advice. Downloaded rom manager and renamed all my backups with their proper tags.
Going to give Epinters CM10 a go.

For all the lazy kids out there, always create a Nandroid before going to any new ROM.
It's only one extra step, and it beats flashing with a SBF and "hoping" for the best...

How to install custom ROM?

I know there are tutorials on how to do this stuff, but I don't understand some steps, can someone list the steps like every one of them for me including backup which is really important to me, and also what to do after I flash the rom

Could have asked on whichever tutorial thread you've read, as it would be easier than having to rehash the same thing on a new thread.
Root your phone, install xRecovery, install rom with xRecovery, use rom.
Ya I know that but it doesn't tell me about backing it up and restoring after a flash

Your contacts should be backed up anyway, your apps can be done with Titanium Backup or AppBrain, and anything on your SD is unaffected anyway so you don't need to back it before, but should have one anyway.

[Q] Is there a way to install kernels by just using the phone?

[Q] My pc broke down lastnight and am not able to use adb. Is there a way to install kernels by just using the Thunderbolt?
If you can point me in the right direction I would appreciate it sooooo much. I'm just a basic user so I don't know much about installing kernels besides using adb.
Thanks in advance....

which kernel are you trying to install?
there is a new kernel, that you can flash through recovery, all the older kernels out there must be pushed through ADB.

I'm trying to install Adrynalyne's 2.6.32.21 [Latest Version 1.8] [Updated 3-29-2011]. I thought that all kernels had to be pushed by adb or installed threw amon_ra because of scripts. I'm glad these new kernels don't have to be pushed anymore. Thanks for help nosympathy!

Nope. Just install and go! As a heads up: It's usually preferable to make a backup using ClockworkMod Recovery/ROM Manager before installing anything.
Well I have a backup of my stock ROM already. Should I let it back up my custom ROM as well? Will that erase the stock backup?

yeah you should prob take a backup of your current setup. the whole idea is that anytime you install something, you should have a backup in case the install goes bad (rarely does though). having a backup of your stock ROM is fine in a last resort kinda way. but i'm sure you'd rather restore right back to your custom ROM should something happen.

[Q] Remove Honycomb

I have Htc Flyer.
I update it from Gingerbread 2.3.3 to Honycomb 3.2.
I want to downgrade it again >>>> How can I downgrade it ?????????????
If there is a 2.3 rom for your device then flash it, or if there is a stock rom flash that. Next time you do an update make a nandroid backup, so if you dont like the new rom then just restore back

Yes i have ClockWork Recoveries that i manually named so i know what rom is what rom at any point i can switch to and from any backup and access whichever version i choose at a moments notice in my opinion you MUST rename them because you know the default name is something like "2012 08.04-12:34:26" just fully remane it so you know what it is!
Its ok to rename in rom manager before you make a backup, but never rename the backup file on a PC and then flash the file, it wont work

Roms

I have meanrom v. 0.6, do I have to install v.0.7 or any other before installing v. 1.0 ??

Nope, you can wipe cache/dalvik and flash 1.0.
And the rom wipes the caches upon flash so you don't even really need to do that, but its a good habit to get into.

If you look on the mean rom thread, the developer of that rom has an installation posted for how to install each update. It also helps to ask questions in that thread, because you get a lot of users of that rom to answer questions like this, and it is a good community. I hope I have helped.

Little off topic but... I know you can use 'MyBackup Root' to backup your homescreens. Not something I make a habit of doing but it does work. You'll have to re add your widgets but it will restore most everything else.

You can back it up in titanium backup. It is a free app in the play store. Just back up [DESKTOP] HTC sense. If you are using a third party launcher then back up the app in titanium back up.

If you're flashing mean rom on top, all you need to do is dirty flash (no wiping) and all your apps, setup and even launcher/layout will be the same

if i may ask, why should i not make a habit of this. i just don't want to re-configure all of my launcher settings/layout.

You don't have to.just don't wipe and flash over itself. You won't lose anything

Restoring a Backup

Hey everyone, I have a quick easy question:
I'm running Paranoid Android 2.23, and Dagr8's Kernel.
If I make a backup, and try switching to another rom, briefly, can I simply restore my backup and have everything as it was? Or will I need to flash the rom / kernel again and then do a restore?
(So basically I wanna go from paranoid android, to a flappjaxxx rom, if I don't like the flappjaxxx rom, can I easily just restore back to my paranoid android rom?)

If he made a backup using twrp he can simply restore the rom safely. No need to flash again.

Incorrect....and incorrect.
A nandroid will do the job. However, if you're using TWRP, make sure you backup all partitions. I've seen cases where .android_secure gets deleted, requiring a large number of apps to be reinstalled. If you're using CWM there should be any issues.

Yeah, sorry, misread that. Thought he was just switching kernels. Nandroid backup is the quickest way to do it. I'll let you know, I try most roms. His is very smooth, fast and basic. My phone heated up very quickly with it. It is also not being developed anymore.
