I have a problem booting my Nexus One. Is it possible to restore the system on the device? I have access only to fastboot but the adb commands are not working since it's not booting. My bootloader is LOCKED. Is it possible to download the signed ROM to restore the system from the fastboot?
Thanks.
You would need to unlock the Bootloader but yes, you can use fastboot to flash the .img files from a ROM.
Yes, if you agree to erase your data.
Read Wiki, look for Unroot/restore guide, PASSIMG.ZIP method.
Thanks for the reply.
I wish not to unlock the Bootloader. I come across some images from HTC, on this link http: //developer.htc.com
Can I rename it update.zip and put it in the SDCard and update it throw recovery.
Thanks Again
Please READ the wiki. BEFORE asking additional questions. If you don't find your questions answered - THEN ask. Your last question IS answered, in BOLD letters. Here, quoting:
Attention: Latest Froyo stock ROM - FRG83 - doesn't flash using PASSIMG.ZIP method. Use FRG33 for stock ROM and follow the additional steps below to install FRG83.

Hi,
I'm trying to revert my htc to it's factory state with the default rom provided with the device and unrooted.
I was able to restore the backup made by using the recovery options frim Mvx method but i still have all the recovery options available instead of the limited ones provided by factory, how do i change this?
I already tried executing the following commands:
adb shell reboot bootloader
fastboot erase boot
fastboot erase system –w
fastboot flash system system.img
fastboot flash userdata data.img
fastboot flash boot boot.img
fastboot reboot
But i get some errors , can anybody help me?
Thanks!
If you get come errors, them they should be posted also.
You could revert, flashing the original RUU.
I get the following error:
erasing 'boot'... FAILED (remote: not allow)
Thanks.

remember to have the goldcard inserted during the process!!
I was able to do the process you described with sucess, but what i really want is to recover the backup made with nandroid and leave the device unrooted.

You have to root the phone, flash the recovery (recovery-RA-tattoo-v1.6.2.img) and simply delete your apps uploaded to the phone to root it up, example: m7, tattoo-hack.ko, su, flash..etc! WITHOUT replace the patched boot.img by Mainfram3.
Then you can start to make your nandroid backup without root.
if you want simply un-root your device you've to reflash the original stock boot.img and delete apps uploaded to the phone to root it.
but I suggest you to start by a clean flashed stock rom.
any chance for a quick tutorial? or at least a link to a post explaining? or it's enough just to flash one of the oficial ROMS from the other post?

all that you need is on top of "Click Android Development" forum's section.
btw you've to follow this to flash your Tattoo with the latest firmware: http://forum.xda-developers.com/showthread.php?t=603286
then root it with the links provided by this thread: http://forum.xda-developers.com/showthread.php?t=645742
I suggest you to do it by the hands and discarding the 1-click root.

Ok, thanks, will do

As i said before i've done that and it works.
But i want to do is:
-Restore my stock firmware (Nandroid Backup) that i posted here
-Unroot and place the default boot on the device so it stays like when i bought it
I already restored the rom using the recovery with the recovery options provided by the 1click method but how do i restore the boot that i had previously and unroot the thing?
is an update.zip or a RUU .exe?
It's a zip file with system.img , data.img , boot.img and nandroid.mds .
It's a backup generated by nandroid.
I tried to restore the backup from fastboot but i got the errors posted on first page "erasing 'boot'... FAILED (remote: not allow)" .
I have just rooted my phone without unlocking my bootloader and would like to flash but without bricking my phone.
Can someone please post a how to guide to update image?
Did you use that guide?
http://forum.xda-developers.com/showthread.php?t=710842
So why didn't you continue to flash custom recovery?
And when you finish it, use the flashing guide found in each ROM's thread, or use "Install ROM" section from the second guide:
http://forum.xda-developers.com/showthread.php?t=636795
Why would you think that the guides aren't posted yet, and didn't just look at the stickies?

Thanks for the answer.
Yes I did use that guide and I did flash Custom recovery. But if you read what I wrote in my first post you would notice, I asked for flashing of image not custom ROM.
So what I'm looking for was a adb way to flash image, and the guides you refer to use fastboot not flash_image.
But thx. anyway.
adb can't flash image.
The only thing you can do over adb, is call the flash_image binary that you call from Terminal Emulator.
Having the bootloader locked, fastboot flash is not an option, so I guess there is nothing to use but flash_image.
The syntax is the same: where you would use "fastboot flash", write "flash_image" and keep the rest.

you may also create an update.zip if thats easier for you
Hi guys,
I've been having some persistent trouble with my device and have been advised to reflash to see if that fixes my problems. Someone suggested to me on a previous thread that it was possible to do this without erasing all my data and apps and such, but I had always thought that reflashing (following, for example, these instructions) would wipe my phone completely. Am I just completely wrong or is there a different method which avoids wiping the phone.
The exact advice I was given is as follows:
Fastboot flash the images separately. Don't flash the userdata.img. Will keep your data.
Click to expand...

My confusion is really with the statement "fastboot flash the images separately" - the only image I had thought to flash was a fresh copy of the stock 5.1 ROM I'm running, and surely this would wipe the phone?
Apologies if I'm missing something obvious - I'm still very new to the business of rooting and custom ROMs.
EDIT: Forgot to mention, I'm running stock 5.1 ROM over the latest leankernel (on an N6 of course).

The information you were given is correct. You can flash all the images separately, excluding the userdata image, and you won't lose data. You will, have to root again and reflash TWRP.

So just to clarify:
From my rooted device (without unrooting first) I could follow the instructions in, for example, the link I posted above to fastboot flash just the stock ROM and end up with a working (but now unrooted) phone with all my data?
I would then have to re-root and install TWRP though, which **would** wipe my data.
Correct?
Sorry to be persistent, I just don't wanna brick my new baby!

I understand your persistence, no need to be sorry. Yes, that is precisely the procedure.

Re-rooting and installing TWRP should not wipe your data (assuming you already have an unlocked bootloader). Also, if you do not fastboot flash the recovery.img file, you will maintain your current recovery. Someone please correct me if I am wrong!

So basically rather than running:
fastboot flash-all
Click to expand...
Click to collapse
I should just run something like:
fastboot flash [<filename>]
Click to expand...
Click to collapse
Where filename will include "boot.img", "cache.img", "system.img" and "radio-shamu....etc.... .img" but NOT bootloader.img or recovery.img or userdata.img" And hopefully all will be well?
EDIT: Particularly unclear as to whether I have to flash the bootloader image first (and then reboot into bootloader) before reflashing the radio, boot, cache and system images, or whether I can leave the bootloader as is (currently unlocked).
EDIT 2: Found a pretty comprehensive guide to my exact problem on reddit for anyone who needs help with this in the future!

Follow method #2 here:
http://forum.xda-developers.com/showthread.php?t=2954008
Excluding the factory reset of course.
I've been flashing radios no problem but I have no expediting flashing bootloader and recovery with wug or even where to find the proper files but I assume I should do it.. Can anyone post a video or step by step on how to do this?
you download a factory image, then unzip it, then pull out the bootloader.img and flash it via fastboot. or you can grab the bootloader.img, and put it into a twrp flashable zip and flash it. its very simple, if you need a root toolkit to flash it, then you shouldnt be flashing anything until you learn how to do things properly.

I have a backup and can enter twrp but it will not allow the restore saying it is read only mode
How do i get this to restore please? I cannot so a restore via hisuite and it will not boot into the system
Help is very much appreciated
Anybody?
What do you mean "read only mode" ? Encryption? Or you set read only on the first twrp boot?

I was following the guide to rebrand it and it says to use read only mode. I don't know how to make it read/write or even use it properly
Which guide are you following? The rebranding guide requires to flash the no-check-recovery.
Anyway, try reflashing unofficial twrp in fastboot again and boot to recovery. It should ask you again to allow system modification or read only. Make sure to allow system modification. Then try to restore your backup.

Hi, I will try that when I get home. I was following the sticky thread on here. I had already got root and was following the instructions to unbrand and for some reason wouldn't flash the new unbranded rom and went to bootloop.
if its reado nly mode disable any protection for unlock screen then it works
ive managed to flash back to stock recovery and can lock/unlock bootloader. however it still wont boot up and keeps going back to the erocovery. how can i get a rom on it to boot up please?
Bump
Anybody? I'm trying not to have to pay for funky Huawei
