I just switched over to HTC TB last week. I rooted it and put in Tesla Coil 1.7.1., which runs magnificently.
But I feel I should update it to Gingerbread.
Would that be possible by just flashing a GB rom?
Or do I have to do a manual update first?
Thanks for the help
Everything is new to me now since I switched over from Droid X.
If you have a custom recovery, which you should...then you just flash the ROM (from recovery) and its recommended radio (from bootloader). Oh, and wipe data/cache obviously.

Yeah, I'm using Rom Manager to reboot to recovery.
So if I just flash the ROM and the recommended radio, my system will update itself to 2.3.4?
Would you happen to know how to REVERT back from 2.3.4 to 2.2.1 also?
Just in case things don't go well.

Just make a nandroid backup. Then if you don't like GB, you can restore your nandroid backup and flash the old radio back.

Oh wow, much simpler than Droid X.
For Droid X. I'd have to SBF back to Froyo from Gingerbread and only then am I able to reflash my Nandroid backup of a Froyo ROM.
Thanks for the advices!
Time to go ROM hunting
Quick question. Can I do a nandroid restore after wiping data, cache and dalvik?
If you chose to put it in your external SD card when you made it, yes. wiping the big 3 doesn't wipe the SD card

So i will be able to go back to my original ROM just as I left it even after wiping the big 3?
Yup! I've got a back ulbof every ROM except MIUI, haven't flashed it yet! Haha

I have a nandroid on my internal that has endured several data wipes and sbf's. It is a backup of my stock phone before flashing anything. I backed it up in both places just in case.

Well, that depends. If you upgraded to say, Android 2.3.5, then you have a different kernel and the kernel is NOT backed up via Nandroid. So unless you are still on the same android version, then you should SBF back to the base OS version you were on. This was tested extensively about a month or so back and it was determined that a nandroid restore doesn't restore the kernel.
Otherwise, nandroiding back should get you where you were before.

Good to know! I missed the tests done, I thought it backed up everything.

So if MIUI is saying that it is running Android 4.0.3, and CM7 is Android 2.3.7, then is it not ok to nandroid back to CM7 from MIUI?

No, it should be fine. 4.0.3 is STILL using the same kernel. 4.0.3 is the OS version, not necessarily the kernel version.
Since the bootloader is still locked, flashing the DX2 MIUI still keeps the 2.3.4 kernel. All that gets replaced are the system files. So, nandroiding back to CM7 (which is what I did) is fine because you are still running the same kernel.
At least, that's how I read it when I researched a little on this and with some other people posting their explanations as well.
The reason you shouldn't flash 2.3.4-based ROMs over 2.3.5 is because the kernel version was changed. Remember, the kernel can ONLY be updated via a Verizon-approved OTA. The 2.3.5 update is not an official release, but it DID come from Motorola servers, so it has the signature in it that the X2 is looking for when the kernel is attempted to be upgraded. Hence, that is why flashing a 2.3.4-based ROM over a 2.3.5 image is not a good thing. Same goes with flashing a 2.3.5 ROM over a 2.3.4 image. It's just not a good idea and could pose problems down the road.

Ok, that makes sense. I figured it would be fine but didnt know the technical details.
I've flashed my 2.3.4 backups over 2.3.5 quite a bit since my cheesecake backup is 2.3.5 and I've never had any issues. Do we really know if the kernel changed? I never really looked at the kernel version on 2.3.5.

Back in December, I asked the question about nandroiding and if it replaced the kernel. Motcher (and ashclepdia) helped out with this one. Motcher SBF'd to 2.3.4 and then nandroided back to Eclipse 2.0.3 (which is 2.3.5) based and the kernel version came up as 00005 which is the 2.3.4 kernel. So, Nandroiding does NOT replace the kernel.
Here's the posted that he posted about this:
http://forum.xda-developers.com/showpost.php?p=20808392&postcount=20
It may be that the differences are minor enough that it won't cause issues, but if the official 2.3.5 ever comes out, it might be best to always SBF back to 2.3.4 if you have to just to be on the safe side. I guess the moral of the story is, do this at your own risk.
Ok I tried to nandroid back to cm7 from Miui and I got a md5-sum mismatch message, and I wasn't able to go back. Do I need to wiped the big 3 every time I nandroid ?

No. That means the md5-sum hash key that was generated after the backup was created isn't matching with your nandroid backup. It means possibly your backup is corrupted.
Wiping the big three has nothing to do with nandroiding.
Uninstall bsr -either cm7 or orig. Then reinstall cm7 bsr. It worked for me On cm7. BTW Be sure not to use any spaces when renaming.
failed restore
So im trying to reload my backup from my sd card. I have made 2 thus far and neither work.
I am on the Rogers network on a i747 with the dlk4 baseband. CWM, rooted, stock rom. When i try to restore it loads a few things (ie. system), and starts loading the DATA portion. Which at this point i get an error message. I reboot it, and my phone gets hung up at the samsung loading screen.
I have tried wiping the big 3 and also under mount and unmount i formated system before restoring as well with no success.
Could it be that my version of CWM is 5.5.0.4.. And, from my understanding I dont think it would be the cause, but maybe because i made the backup after being rooted and flashing cwm

Tried installing Eclipse 2.3 and it failed (due to user error, DOH) and had to sbf back to 2.3.4. If i root and go back up to 2.3.5 could i just restore the backup i made of eclipse? Or would something not work there?
Edit: yup, I can. Admin can delete this thread.
Just for future reference, you can restore any nandroid as long as the nendroid is on the same android version you are currently on. For example, you can't, or at least shouldn't, restore a nandroid of Eclipse on 2.3.5 if you are currently on 2.3.4. And visa versa.

Yea thanks, I remembered that so after I sbf'd I rooted and installed 2.3.5 then restored the eclipse back up I made.

Do I need to restore the ROM I made my nandriod from first? Or can I restore my previous nandriod off any ROM I'm currently using?
I'm sure this has had to been asked before, but maybe I'm using the xda search wrong.

Just wipe in Aron Ra and then restore from your nandroid. I commonly jump from Rom to Rom, just make sure you wipe in between.
Yupyup your nandroid reverts you to whatever that particular nandroid saved..

Thanks guys. I'm not sure what is wrong with my phone. Clean ROM 4.3 was the only one that would work for me, until this morning. I finally got RAGE1.8 to work. All other ROMs would boot loop, including all Clean ROMs after 4.3. I had been reinstalling Clean ROM and then restoring the nandriod, I'm glad I can skip one step if I need to go back.
Make sure you wipe before you restore a nandroid. If you don't it could cause it to bootloop.
Also if you're s on it could be an issue with kernel compatibility

I am S on. Maybe I'm wrong, but I thought loading the PH98IMG file in the bootloader was loading the kernel.
First, you really should S-Off, it will make it a whole lot easier, it will allow you to jump from Rom to Rom a lot easier. Be careful because some new roms call for the latest firmware to run correctly.

It has to be the ph file from the rom you are on
I have been using Eclipse 2.3 for sometime now and I have occasionally booted into recovery and backed up everything. Having come from the OG Droid, I am used to Nandriod and know how to restore from a Nandroid backup but the DX2 under eclipse is confusing me.
If I flashed a different ROM and then decided to go back to my Eclipse setup How would I go about restoring the Eclipse backup I made?

Eclipse runs on gb 2.3.5. Cm7, 9, 10, AOKP, and pretty much every other rom runs on gb 2.3.4. You would need to make sure you are running 2.3.5 before you restore your nandroid backup.
So, for example, if you're running Cm7 and you want to go back and restore your Eclipse backup. You would need to SBF back to 2.3.5, root, install cwm recovery and restore the backup in the custom recovery.
