I'm fairly new to Android as well as Linux, but I was curious about how the PC36IMG.zip and nandroid backups relate to each other. I'm planning to flash the latest rooted stock PC36IMG.zip (1.47.651.1) and then a nandroid backup of what I'm currently using which are a combination of ROMs and patches with baseband 2.05.00.06.10 and 1.47.651.1, will this cause compatibility issues?
At a higher level, what does a PC36IMG.zip write and what does a nandroid backup write?
The PC36IMG.zip is actually a special ROM, the first which allows su permission, and the second which allows full NAND unlock.
The Nandroid is really just a way to backup and restore the images that are on your phone when you perform the operation.
The PC36IMG.zip is used to unlock, and custom ROMs available in the dev section are used after getting full root to the phone.
so basically, before you flash anything, you do a nandroid backup incase something messes up. Then you use the PC36IMG images to obtain root, then you go to the dev section and pick a custom rom and flash it
And to answer you question, doing a nandroid restore after you flash something (I think) is pointless because it replaces everything on the partitions (except possibly the radios but I am not sure)

Sorry if this sounds stupid, but I'm a little confused. I'm aware of all the S-OFF, permarooting etc and the necessary ways to get them. Before I go through with these guides however, I'd like a backup of some sort.
I know ClockworkMod is a custom recovery and you can perform nandroid backups with it, but I also understand there is a default recovery mode you can access from the bootloader that can also do that. Obviously I'd like to make a full nandroid backup before I make any permanent changes.
However, when I select 'Recovery' from the bootloader, my phone goes to a black screen with a generic phone icon and a red ! in a triangle. Why could this be? It is a standard UK T-Mobile Desire Z with no modifications aside from a Gfree S-OFF that was reversed again by copying the backup partition back.
That is the splashscreen of the stock recovery. Press Vol-Up and Power to get past that screen - but you won't be able to do a nandroid unless you have a custom recovery installed - sorry!
Thanks very much for that info. So there's no way of making a nandroid backup before I do things like permarooting? Will the unroot option in Visionary reverse that?
Presumably there's a way of reverting from ClockworkMod to the stock recovery?
the only time you will be able to make a backup is when you install clockwork. No clockwork no backup.
Use titanium backup for the settings and apps and then install clockwork and then do nandroid. if that doesnt work you have your TB to restore.
You can also try to "adb pull /system" and pull everything to your desktop.,... but pushging it back will require skillz.
If you want to revert from clockwork to stock recovery you need to flash stock recovery but do not do it with an incompatible rom.
Thank you, oh wise one!
Don't worry about the fact you can't do a nandroid backup before you root the phone, because it's easy enough to un-root.
You can do the nandroid backup as soon as you've got root/S-OFF, installed ROM Manager and flashed Clockwork recovery. It's very important to do this before you flash any sort of custom ROM. I am amazed by the number of people who seem to flash a custom ROM straight away with no backup whatsoever !
Hey, this may seem like a silly question but i would rather ask it than brick my device.
I have rooted and s-off my stock rom, i have installed all my apps and settings and ive got it just the way i like it. i have created a nandroid backup using clockwork mod.
I now want to try Gingervillian rom, ive got titanium backup to install all the apps back and that but what i want to know is:
Will i be able to restore my stock rom from the nandroid backup with all my apps and setting in tact, even though s-off is set and its rooted. i know a read somewhere that flashing a stock rom on a phone with s-off can semi-brick it... so will clockwork recovery do the same?
When you make a 'nandroid' backup via ROM manager/CWM Recovery, it makes essentially a carbon copy of the current setup of your ROM (not your radio, S-Off status, etc.). Literally everything is perfectly as you have it now. It just like doing a full HDD backup of your computer.
When you restore this backup, it simply brings back your ROM from exactly how it was. There is no effect on your root or S-off, or your radio.
So, if you do a nandroid backup, then wipe the device and flash another ROM i.e. Gingervillain, and make a nandroid of that, you can then freely switch back and forth between the 2 (or more) recoveries via ROM manager/CWM Recovery, with no issues.
The issues with bricking as you're referring to are if you for some reason try to somehow flash a non-rooted ROM, which would most definitely cause issues. In order to get back your phone to stock-stock-stock-stock (unroot and S-on), you will need to follow unroot instructions and flash an official unrooted RUU/PC10IMG.zip to get back to everything as it came out of the box.
Hope this helps, let me know if I need to clarify.
thank you very much matey much appreciated!!
I know that I have seen this question asked before but I can't find the post. I broke my evo (let's call it #1) and I am trying to restore evo#1 CWM backup onto evo #2 the new phone that I just got. I have put the sdcard from evo#1 with its latest backup into evo#2 and have booted into recovery.
I remember seeing that you can't do a full restore but rather to use Advance Restore but I don't remember which components to restore and which not. I think that I restore all but WIMAX bacause WIMAX is different for each phone.
Anyone know ??

Generally, I don't believe it's recommended to restore a backup from one phone to another. However, I've seen reports that it it can be done. As you assumed, you are correct by NOT restoring the wimax. If you were to do that, it would restore the RSA keys of your old phone, overwriting your NEW RSA keys. You don't want to do that. So remove the wimax.img from your nandroid backup before you restore.
Also, I'm not positive on this, but I do believe that if your old backup was made on a certain hboot version, that you need to be on the same hboot version when restoring that backup. (lets say you when you created the backup, your hboot version was 2.10, then when you restore your backup, be sure the hboot version on the new phone is also 2.10). The reason I believe taht to be true, is because I had always had hboot .93 on my phone, and all backups I had ever made were when I was running .93 hboot. I then downgraded to the ENG .76 hboot, (to use fastboot), and I tried to restore a backup that had been created when I was on .93 hboot, and it did not go well. After the backup restored and I rebooted, it booted straight to fastboot, and that was the only place I could get. None of my old backups would restore. I then switched back to hboot .93, and my backups restore perfectly fine. So that is what led me to my conclusion. Good luck with your quest. ( i personally recommend just starting fresh, and not restoring an old backup, just to be safe)
k2buckley got you covered, but restoring a backup from an old phone to a new one WILL cause you problems, and the easiest way to avoid it is to not do it.
The best you can do is backup your apps via titanium backup and your launcher settings, transfer those folders to your new phone. When restoring the apps, do only app and data, NOT system settings.
Thank you both for the reply. Based upon your feedback I decided to do a clean install of everything.
You're welcome; just trying to make it smooth as possible.
Hey guys, so I'm a noob and need a little bit of help. I just downloaded this:
http://forum.xda-developers.com/showthread.php?t=1219407
Now, what do I do with it? Also, will I lose all of my data by flashing this onto my phone? (ie: my texts and my homescreens, etc?)
Thanks!
are you rooted? if not...

once you have clockwork recovery and all that, boot into recovery, 'flash rom from sd card' (after putting the zip file on ur sd) and ur good.
If you dont want to lose everything, after root, download titanium backup and run that. you will be able to apply most of your stuff back on once you flash a new rom.
howbout some thnx -.-'
I'll give you some thanks for that succinct explanation of steps to take.
I'm ready to root with unrevoked - guessing I should use the "flash and recover" version instead of their "forever" one?
I installed Titanium backup, which I'll use after rooting to backup pretty much everything that it can grab.
Then, I'll use the SD card-based install that you mentioned.
I've read that I should do a full wipe before installing the OTA ROMs being offered - is another tool needed for that, please?
- ooofest
You've got it. The newest version of Unrevoked has made the "forever" one obsolete.
You will be able to perform all the wipes required from within Clockwork Recovery.
Also, make a clockwork backup (nandroid) as soon as you have root, so if you run into any problems flashing roms you have something to restore.
Hey Guys, I have searched for this but I cant find an answer so I just wondered...
Say for instance I made a Nandroid backup in Clockwork Recovery 5.x and then my friend who has Clockwork Recovery 5.x and the exact same device HTC Wildfire (Buzz) used my Nandroid backup in the same directory but on his SD card then would Clockwork Recovery be able to recover his device from my Backup?
Thanks in advance.
Yes it will work. (Barring issues like MD5 mismatches etc. You should be preferably be having the same CWM version, and, if possible, he should use your SDCard to restore, since, there are cases when you transfer Nandroids from once place to another, they don't play nice)
Anyway, another alternative is to simply use fastboot. Assuming your friend has S-OFF'ed his device via Revolutionary, he will simply need all the IMG files from your backup, and, that should definitely work irrespective of CWM versions, and other limitations.
