I have a quick question. I wanted to install a certain ROM and was required to use their Boot File. I installed it and I then installed the ROM. All is great, however I was wanting to return to Stock and flashed the Stock Boot.img. My question is, what if I want to now stay with the custom ROM. Whats the harm? On top of that, how can I verify that the Boot was flashed?
Thank you
Boot.img contains the kernel and some other stuff to help the phone boot.
The worse that could happen is the phone wont boot. To fix this just flash the correct boot.img
If you want to stay on a custom ROM, Just reflash the boot.img and then the ROM. you can swap back and forth from stock to custom as many times as you want. Just make sure you have the right boot.img(s) in case it fails to boot.
Great. I askked because I flashed a custom boot.IMG and then a custom rom. Then went back to stock Rom without flashing a new boot and it worked fine. Is therw a way to see what boot.IMG is currently flashed.

Several months ago I purchased a NS4G on Craigslist. I wanted to use it as an iPod touch without the data. It came rooted with SuperUser. The phone keeps prompting me to OTA to 2.3.7 (it's currently on 2.3.5) I used Gingerbreak to unroot and it worked, SuperUser is now gone. However, ClockWorkMod Recovery is still present and 2.3.7 won't install. The phone reboots, goes to about 1/3 of the progress bar, and then fails. I just want to get the phone on completely stock 2.3.7, in preparation for the coming 4.0 OTA.
Hopefully the solution doesn't involve flashing a custom ROM, I've never done that before. Thanks!!
No need to get it OTA, you can just flash the stock ICS ROM found in the stickies of the development forum of this phone. Of course follow instructions closely.

But I'm selling it and need it to be completely 100% original and stock, which is what the buyer requested..
You want to use fastboot to flash a stock recovery. Peter Alfonso has them all listed on his site.
Thanks. I'm really not familiar with fastboot, and is there any way you could give me a link with instructions or the files I need? My build number is GRJ90.
And if there's anyway for me to avoid a rooted stock ROM, that'd be great. Just pure stock 2.3.7.
The stock image on Rom manager has the recovery bootloader included.
Flash a stock gb rom from cwm. You will find a list of them in either general or android development threads, not sure which. Completely stock, unrooted and as far as I remember the stock recovery is included. If not then the person will never know anyway as if someone doesn't want any non stock features then they won't know how to get to recovery anyway.
Actually I don't think they have stock recovery. Just flash the stock rom and then fastboot flash the stock recovery like was mentioned above. All you need to type is:
Fastboot flash recovery xxxxx.img
Xxxxx.img is the name of the image file you download.
Don't cheat the buyer...Tell him exactly what he's buying...And that you returned thedevice back to stock again.It's just not worth it.
Hello, my device is currently running LeeDroid's ROM and I was looking to test out other ROMs for fun. One example is TrickDroid. I noticed that each thread provides a boot.img to be flashed in fastboot. Must I do that before flashing each ROM and after backing up and wiping? Thank you!
If both ROMs are on the same base then no, you shouldnt have to flash each time..
Newer bases require newer boot.imgs,
The worst thing that could happen is the ROM wont boot, To fix that, Just flash the boot.img
I would love to thank you but I reached my max Thanks for today. I will come back tomorrow
If you get a bootlop, you should erase the cache or just flash the boot.img as said above
I intend to flash a custom ROM on my One S. I've noticed all roms require flashing boot.img
I did some searching on what boot.img is and found that it has the kernel and booting instructions.. Now, if I flash a new boot.img and some time in the future wanted to restore the stock rom, how do I restore the original one?
I have my nandroid and apps backup. Is that sufficient?

Restoring the Nandroid will restore the boot image, it is backed up during the Nandroid
If you use TWRP as your recovery, you won't need to flash boot image separate. TWRP bypasses the HTC restriction, allowing the boot image to be flashed with the rom.
If you want a copy of the stock boot.img, I know LeeDroid's Supreme ROM has it linked in the thread there. If you dig that thread out, you can download it and keep a copy of it.
Or run ruu if u want to go back to stock completely

Thanks all..
I should start my journey then
Good Luck and enjoy
Do as it seems you have done--read OP pages and beginning and ending pages of threads and include System wipes when wiping before flashing--
An update..
As I begun testing various roms.. I found out that neither TWRP nor CWM could manage to flash the boot.img from a nandroid.. I had to flash it via fastboot EVERY time.. TWRP took around 5 min just to flash the boot image and although it reported success, it didn't work! I got stuck at boot animation after flashing my stock nandroid until I flashed a stock boot.img..
No big deal, but just a note for those adventurers..
Flashing With RUU
I'm really new to Android. I've rooted my phone and installed something called TWRP. So will installing a RUU restore the original Boot Image and the Bootloader ? Please repli. Soon Thanks in advance.
AW: [Q] Restoring stock boot.img
The RUU will install stock recovery, stock boot.img and stock rom to your phone. You will lose root, custom recovery and your custom rom.
You have to relock your bootloader for running a RUU.

Ok so i've finally decided im ready to unlock and flash. My question is this: whats the deal with returning to stock and redoing everything on certain roms? Can anyone explain to me the variables here?

once you have your device rooted and have a recovery installed, make a nandroid back up your stock rom, flash whatever rom you want, then if you need to go back to stock rom, just flash the nandroid back up you made. If you want to go 100%, then you will have to find the stock recovery image, and flash that over your custom recovery as well, then just use OTA Rootkeeper... and temp unroot your phone... and viola, your 100% stock again.... but if you plan to go back to 100% stock then DO NOT UNLOCK YOUR BOOTLOADER!! there is no way to lock it again once you unlock it.
I think it's worth while to note
currently the only custom recovery that is able to flash stock is CWM
TWRP is not able to flash a stock rom

If you flash a stock ROM using CWM you will lose all data on your device, including any backups you made using CWM. So be sure to backup those files to your PC (they're located in the clockworkmod/backup folder of your internal storage) before flashing the stock Asus ROM.
I've been changing my ROM's throughout the day and have basically memorized the process of flashing CWM, root, and ROM's by now

Ive read about problems reflashing ROMs when youre on the CM or AOKP. Need to return to stock, then flash other ROMs, dunno why exactly. So is it enough just to restore my stock nand backup or do I need to do something differently? :good:
This is exactly what im talking about. What are the rules when coming from cyan to a stock flavor?

So lets say right now im ready to unlock and root. I would want to unlock the device, then root, then flash CWM (not twrp) so i could still retrain (and boot in to without reinstalling) my original rom? Because i still want to titanium my apps.

not sure if I understand your question right, but yeah you can use your stock rom when you root or flash cwm. Untill you wont wipe anything within CWM, theres no reason you coulndt use it. But dont forget to do backup of your stock mate.
I think part of the confusion is defining what "stock" means, and I've got two different views on it over the past few days:
COMPLETE STOCK means flashing ASUS' original stock firmware, which completely wipes out everything on your tablet (including your nandroid backups) and CWM and takes you back to a fully stock tablet (except it will still have unlocked bootloader). From here, if you want to install ROM's like CleanROM or Hydro you have to re-flash CWM each time, then flash the appropriate ROM.
MODIFIED STOCK would be making a nandroid backup of your stock settings as soon as you flash the stock ROM, install CWM, then back it up and you can revert to it accordingly. I don't know if this would break things when you tried to flash Clean/Hydro and so maybe someone can clarify.
I wanted to try both hydro and cleanrom so I spent many hours yesterday flashing between stock/modified stock. Its kind of a pain, but all part of the learning process.
And one thing I want to note both for myself and for anyone else: if you flash stock without removing CWM it'll give you the broken bootloader logo (android on his back w/ exclamation point), and my solution has just been to do a 'wipe data' from the fastboot menu and the stock will work fine. What I mean by this is I've done this at least three times, where I flash STOCK from within CWM and when I try to boot into recovery, I'll get that android. That's because STOCK completely erases everything including CWM so in order to restore the normal operating procedure, you just need to 'wipe data' from within the tablet.
Hope my understanding of these situations is correct, if not anyone can feel free to correct me
People like to experiment with their tablet, they get easily bored with the same thing.
So they go back to stock and flash another rom like Hydro which is stock based because when you flash CM or AOKP it won't let you just flash to Hydro.

NOT TRUE!
It should be noted that TWRP is now more functional than CWM. TWRP can now flash stock ROMs just fine. It can now restore complete nandroids, including /boot, and it can now flash from and store to the external SD card. It was just recently updated for this, which is why all the information until now has said to use CWM to flash the stock ROM. So, go ahead and use TWRP. It's perfect now.
I made a backup on my phone in TWRP and wanted to restore it to get some contact info that I forgot to upload to my Google account. Anywho, I go into recovery and wipe me squeeky clean then restore the backup. It goes through like normal and I boot up but it doesn't get bassed the HTC splash screen. It turns to a black screen that occasionally has a white/grey bar at the top. I loaded a different backup I had and am running fine, but I still need that contact info.
Any ideas as to get the back up to work or if it is no use?

What hboot do you have?
If its 1.14 and you're switching ROMS (your backup is of a different ROM to the last ROM you were using) you might have to fastboot flash the boot.img of the ROM you're recovering.
i think it is a kernel issue
I had to downgrade from jb to ics and I wiped clean, I run into the same problem, I realized jb uses a different kernel, wipe clean flash your choosen Rom kernel update first and then your Rom, it worked for me hopefully works for you

where can i get the stock boot.img or the stock one x 2.20 image to extract the boot.img?
thanks!
is this it?
would this work?
http://forum.xda-developers.com/showthread.php?t=1812459
if i download the odexed stock rooted rom and extract the boot.img, i can flash that to boot, and then run twrp restore to my backed up stock rooted rom, right?
my stock rooted rom was at&t 2.20 firmware.
Hoping I understood you correct, you basically need to flash a kernel first, so I am guessing you can use flar kernel,
http://forum.xda-developers.com/showthread.php?t=1967897
and that should be the stock kernel on steroids, however if that were not to work he has a kernel for jb phones, so I would start by these first.
I really had this issue where I could see my phone in a brick state mode then flashed the right kernel for the right rom, and boom it worked like a charm.
