[Q] Do I ALWAYS have to flash a new boot image when installing a rom?

Hello,
I'm coming from a HTC Desire, and when reading the guides how to install roms on the HOX, the neccesity to flash a separate boot.img for every rom via fastboot was new to me.
Is this always the case? And lets say I have a stable 4.0.4 installation and want to mess around with CM10 - I get that have to flash the CM10 boot.img before installing the ROM, but would I then also have to re-flash my old boot.img before rstoring my old nandroid backup, or is the boot image included in the backup?
Thanks aheasd for an answer,
saxelfur

i guess yes.. you have to re-flash the boot.img of the rom that you are restoring...

Okay, thanks - so I suppose right now there is now way to restore a backup from a different rom on the go. Oh well, I should be able to live without that

You do not have to flash the boot.img before restoring a nandroid backup...Y
ou restore everything, boot.img included.

Not true; if you're restoring a backup which used a different boot.img than the one you already have installed, you need to manually flash the boot.img from your nandroid backup in fastboot.
The reason we have to use fastboot to flash the boot.img is that, thanks to HTC's security policies, it is not possible to write to the boot partition from recovery. Hence when you flash a ROM the boot.img isnt written, and has to be manually flashed. This also means that when you restore a backup in recovery it is still unable to write to the boot partition, so the boot.img from your backup is not written and must also be flashed manually.

Really? I once flashed a kernel and could not pass the loading screen...everything got fixed as soon as i restored my backup...

Lucky for you. But these guys are correct. The only way to flash boot is through fastboot.
Recovery restore cannot restore a boot.img

Yep. Boot partition simply isn't writable from recovery (without s-off). There's no difference between recovery trying to write a boot.img from a zip on /sdcard and recovery trying to write a boot.img from a folder on /sdcard (if there was we would just need to modify recovery to treat new flashes as restores to get around the problem).
I'm not saying it won't work if you don't; if you're switching between Sense ROMs or restoring an earlier version of the ROM you're using then there's a good chance that the ROM will still boot and run fine, but you'll be running with the kernel & ramdisk you had before the restore.

Well shoot. How do I get the boot.img from the stock rom that came with it. It wasn't exactly in standard .zip format for me to extract the .img......

If you did a nandroid backup it's there in plain sight.

bootloop after update

guys i changed my phone rom to stock by a nandroid backup and now i tried update my to 4.0.4
my phone startup but than goes into rebooting again and again so any tips how to fix it???

You also need to have stock recovery to receive OTAs

Then you missed one or more of the following:
-stock ROM
-stock recovery
-stock kernel

What do u mean missed??? Here is the summary restored phone with nandroid restored stock recovery and than update my phone couple times until I reched 4.0.4 where my phone stocked on bootloop and than again restored my Phone with nandroid backup which my u can see Im using it to replay to you

i did flash boot.img from the backup yet it didn't work

You really did a full wipe ? Caches , dalvik cache ..... i have no doubt you restored it correctly but you might forgot something to wipe then. Can't think of any other reason
Edit : also do a full wipe before restoring the nandroid

bootloop after OTA

Hi,
after restoring my nandroid from stock rom and flashing stock boot.img and recovery.img my HOX boots up fine. (CID T-MOB101, Hboot 1.36).
Then i´ve done a factory reset and wiped the internal SD. After that, rebooted the phone, connected it to my WLAN and started an OTA.
No errors there, but after the update Process only boot-loops. I´ve tried fastboot erase cache and the factory reset option in fastboot.
Still boot-loops.
Any Ideas what i can do now?
Thanks!

Must have removed something from the stock nandroid. Try some other backup from nandroid thread and retry the process.

Try restoring your backup once again and see if the issue persists. Maybe your backup is corrupted.
If that is the case, try flashing the Stock Rom with the 3.19 base (Latest) which is available in the development thread.

Or get a "new" stock nandroid backup here and try again !
http://forum.xda-developers.com/showthread.php?t=1975140
If the JB version is not there, get a 2.17 based nandroid matching your main version. And also flash back the 2.17 stock recovery and update again to the JB software.

Thanks to all for your answers. But - if the phone works fine after restoreing nandroid, should the problem really be searched there?
The bootloop happend at first boot AFTER the OTA.
Could it be a problem that i had installed AHRD 20 and a jb hboot and then restored an ICS nandroid (4.0.3) ?
Can anyone point me to an official T-Mobile JB RUU? I used the search, but only can find dead links or ICS Versions.
My only Target is to get the HOX completely stock (and up to date) for selling it.

It could be in the ota ! I had a similar case a while back. We solved that by :
1: flashing the firmware to update the hboot
2: restore a nandroid JB backup
Check for a JB tmob 101 backup if its there you can do the same

Ok, got it working after using a JB T-Mobile nandriod. Thanks again.
Now its time to put hands on the Nexus4

[Q] How to add 3.20.401.1 to a rooted phone

Hi
I have a HTC one X rooted phone with stack 4.1.1
I get a message that there is a new update 3.20.401.1
After download it tells me to reboot. My phone then goes to ClockWorkmode (CWM)
It stoops there. I do not find any zip file to install.
Any tips for this, or should I just ignore this?
Thanks

You just need to flash stock recovery through fastboot again mate then on booting up you should be able to install the update. Or you could install a custom rom with that base without having to flash recovery :good:

Thanks for quick reply.
If I go for a custom room, what is the best out there?
Do I loose anything by not upgrading the stock room?

they are all pretty damn good roms mate! too hard to choose really, just best to flash em, and see remember to make a nandroid backup also
u shouldn't loose anything apart from bloatware

If you want a custom based on stock, i suggest Android revolution, Viper Rom, or SD ROM.

I did try out Cyanogen lastest image, that do work fine.
But I have to look long for how to find out that I needed to extract boot.img from the cyanogen zip file and install this with flashboot.
But now I like to go back to my original rom. I did take a nandroid backup, and also have an older nandroidbackup.
Its not possible to make the phone go back. When I start restor, all looks ok MD5 etc, but then gets this message
Error while restoring /system!
Do I have to do more flashboot stuf to go back?
I am still able reinstall Cyanogen from zip file. But my Cyanogen backup also fail.
Why
Edit. The Cyanogen Image is 4.2.2 and Orginal image is 4.1.1. Could that be any problem?

Are you sure you've made the backup with the same recovery as you are attempting to restore it with?
The Android version shouldn't really matter, but there may be exceptions for some things.

If you are using CWM recovery u should be able to go into the backup file (under clockwork mod/backup on sd) and take the boot.img u need to flash via fastboot there. Put it in your fastboot file and then flash using "fastboot flash boot boot.img"

So I should take the boot.img from the backup, run fastimage and restore it?
Then try to restore the backup using clockworkmod?
I am not user if the backup was made with
recovery-clockwork-touch-5.8.2.7-endeavoru.img or
recovery-clockwork-touch-5.8.3.1-endeavoru.img
Is it important to restore with correct version? If so how to see what version that was used?

I am not able to go back to my old image
Not sure why, but the Cyanogenmod does not give me any Mobil data (3G etc)??
I tried to restore the boot.img from correct backup using flashboot flash boot boot.img and then try to restore.
But still I get Error while restoring /system!
Some note:
I made a backup of my working Cyanogenmod, this I am able to restore without getting the restoring error.
No I also have tried recovery-clockwork-touch-5.8.4.0-endeavoru.img
But there are some different thing going on.
When I first tested to restore my original image, I get menu like this when trying to restore:
Code:
Yes-Restore
No
Go-Back
Now I do get:
Code:
No
No
No
No
No
Yes-Restore
No
No
No
*** Go back
Have I used another clockworkmode to make the backup?

If you want to be sure you use the same recovery as where the nandroid is made with ? Flash the recovery.img from the nandroid folder.
Then flash the boot.img from the nandroid folder, go into recovery :
Factory reset
Wipe cache partition
Advanced - wipe dalvik cache
Mounts & storage - format cache, data, system
Then restore the nandroid.

Thanks
You saved my day.
It seems that the backup was done with CWM based v6.0.2.7
Not sure where I have got this version.
Latest version listed here: http://www.clockworkmod.com/rommanager is 5.8.4.0 and not 6.0.2.7 that I have used
Here http://forum.xda-developers.com/showthread.php?t=1941630 is 6.0.3.2 listed
What is the latest version of CWM for HTC ONE x and where to get it?
And last, what is the best to use

Yeah well after all the replies i thought i chip in give my 2 cents
This is one of the latest i use now.
http://db.tt/SPXdFfPw

Everything is working fine and I start to understand how its connected together.
But there are one thing that still puzzle me, the boot.img
When and why do I need to change that when I go to and from CM 10.1.2 (4.2.2) and Original image 4.1.1
What trigger the need of the change?
Should not this be restored correctly when I restore a backup. (In Clockwork mode)?
Does this work automatically whit Philz recovery 5.6.1.img?
I do like to change image in my phone without need a PC to run fastboot !!

When you change rom you need to flash the corresponding boot.img from that particular rom or nandroid backup.
We can't flash boot.img files via recovery because we have s-on devices so fastboot is a must.

Nandroid of factory state

Hi guys,
Before I rooted and flashed new roms on my M8, I took a nandroid backup of my phone as it came out of the box. However, I can't seem to restore this anymore. I'm not sure if it's a problem with the backup I took or if it's just not possible. I have restored backups of other custom roms and they have been fine.
I'm not that fussed as I'm hopeful an RUU will come out eventually. I'd just like to understand why.
I have an International unlocked M8 bought in the UK.
Thanks!

Hi, mate. I did the back up in TWRP 2.7.0.2 - although now I am on TWRP 2.7.1.0. Not sure if that makes a difference?
Yes I did convert to GPE at the beginning. Here's how I got to where I am today:
1) Flashed TWRP 2.7.0.2
2) Did a nandroid backup of factory state
3) Converted to GPE using Graffixnyc RUU
4) Flashed Skydragon GPE
5) Then I wanted to try Skydragon Sense, so I changed CID to 11111111, flashed stock recovery and did factory reset
6) Flashed TWRP 2.7.1.0 to replace stock recovery
7) Now I am currently using Skydragon Sense
I thought I would be able to restore the backup from step 1 after doing step 5. It would be nice to know I can still go back to the phone in that state if I ever decide to sell.
Thanks for your help!

You need to undo the GPE conversion since it has resized your system partition. Follow this guide:
Going back to Sense from [RUU] Google Edition Conversion.Graffixync UPDATE 12th May
In the last part where it says to flash a ROM, just restore your backup, but have a ROM handy just in case.

I have followed this procedure already (that's how I'm running Skydragon Sense rom now). Before I flashed the Skydragon rom, I tried to restore the first backup I did, but it failed. I have successfully flashed ViperOne and Skydragon Sense though, so I'm sure I have successfully re-converted it away from the GPE partition. I'll try to restore it again now and see what happens.

Stock recovery won't make a backup, only a custom recovery. He did right, flashed TWRP, and make a backup of the stock ROM it was loaded with. He's having issues restoring it.

That's a damn good point. I've only ever backed things up using custom recoveries. Never thought of using the stock recovery. I guess I can never get back to factory stock then.
I should be able to get back to the factory ROM though (albeit rooted and with flash recovery)?

Generally you should boot custom recovery and mare a nandroid backup.Philz allows you to backup your stock recovery.But twrp doesnot.Yes if he has flashed custom recovery without taking the bkup of stock recovery he wont have full 100% stock rom.Also if the op provides details of what version on stock rom and cid he is using then we might be able to get a stock recovery for him.

Booting to and flashing are different things.
I mean:
1: fastboot boot recovery <recovery.img>
2: nandroid backup
3: fastboot flash recovery <recovery.img>
Only that way you are able to perform a nandroid of your factory settings. I believe...

Thanks for your input. I foolishly didn't take a note of the CID before I changed it to GOOGL01 the first time, but I'm definite it began with HTC followed by some numbers.
Before doing a factory reset when switching away from GPE, I flashed the firmware 1.54.401.5.
