So I'm confused..how is this different than the other methods of getting 4.5.91? I know one of then can brick if you flash sbf, but isn't the cwm zip safe?

These are completely safe to flash. They don't mess with your bootloader like the OTA or SBF.

So is there any particular benefit to using this instead of the flashable zip beta #4 thing you have in the dev forum?
Why does the brief mobile site say you need CWM? Your instructions just say fastboot. I am relatively new at this so excuse the stupid question if it is one.
So before flashing this we need to unlock bootloader by flashing the pudding unlock sbf. After that can we gain root by using the root.zip found on the other threads by flashing with cwm

So does this work just as well as the other one that was removed because of potentiak damages to peoples phone? I just want to make sure if I use this I have everything working, like the fingerprint reader.

The download links for the image pack is below those instructions, because those are for something else. Just use fastboot for these.
Sorry, if I am being a bit thick here.
Having installed this update, one should generally avoid installing future OTA's, correct?

Hi Ken,
Could you please help to clarify:
1- I have already been on 2.3.4, using flashable zip for locked bootloader. Anything different between your rom and the previous flashable zip file ? Is your file is final one ?
2- Noting that using 2.3.4 via flashable zip for locked bootloader, I can not flash back to stock 1.8.3 rom (or I have to use the modded stocked 1.8.3 with unlocked bootloader). Can I flash back the stock 1.8.3 (original one) after using your file ?
Hope your reply soon
Thank you very much,
Quang

If you're on the OTA zip... just stay... you've already got a STOCK ROM.
After inputing the command everything seems to be fine. Upon rebooting the phone said unable to boot starting RSD mode. I am currently flashing to 1.8.3 with rsd lite. Any idea why that happened before I try again?

Tks Ken,
How about the possibility of flash back to 1.8.3 ? Can I back after using your file ? If I can, can I upgrade to your file without hard brick my phone ?
Noting that your file is more completed than flashable ZIP file (more img files)
One more thing, after using your file, can I use OTA when AT&T officially announces the final one ?
Best regards,

First up, let me tell you that doing this is not necessay to get the OTA or having a smooth JB experience. The JB OTA installs without a wipe which means the data is preserved.
UPDATE: Google has put up the full image for 4.1.1 [i9023, i9020a and i9020t] . Now you do not need to clean flash ICS and then JB. Follow the part 1 of the guide below and flash the JB image instead of ICS. Nothing more to it.
Thanks anshumandash for pointing it out
That being said, I wanted to have the real stock image on my Nexus S and then Upgrade to JellyBean. Below are the steps that I took.
Go to this GoogleAndroidImages page and download the appropriate image for your phone & download. Since mine is an international version a.k.a I9023, I chose that ROM.
The download will be a tar.gz file. Use a utility like 7Zip to uncompress it. The tar.gz will have a .tar file inside and the /tar file will have a folder. Extract the folder to your PC. For my download, the folder was named soju-imm76d
Next Steps will wipe your phone, completely
Reboot your phone into bootloader mode.
Open a command prompt, navigate to the folder in step 2.
Enter the below commands, the image file names are for my download, modify it to the file names in your folder before running (I assume that you have fastboot working)
fastboot flash bootloader bootloader-crespo-i9020xxkl1.img
fastboot reboot-bootloader
fastboot flash radio radio-crespo-i9020xxki1.img
fastboot reboot-bootloader
fastboot -w update image-soju-imm76d.zip
After the last step, the phone reboots and takes you to the initial setup screen.
Additionally, I reflashed CWM and the the JellyBean OTA along with superuser. Below are the steps for that
Download the OTA from google server. This thread by oldblue910 is kept updated with the latest updates. Currently it has OTA's for I9023 and I9020A
Download the superuser from androidsu website. This is the RC version 3.2
Download the latest clocworkmod recovery touch-version non-touch-version
For simplicity sake, put all the files downloaded at a single folder
Reboot phone into bootloader mode.
Open a command prompt and go to the folder in step 4.
Now execute this fastboot command to flash the CWM recovery. Change the filename to the file you have downloaded.
fastboot flash recovery recovery-clockwork-6.0.0.7-crespo.img
Now using the vol down key choose to go to recovery.
There, using the options, navigate to the install zip from sdcard and first install the OTA and then the superuser zip file.
Reboot. You now have rooted JB
PS: I additionally did a fastboot oem lock and fastboot oem unlock back to back to wipe my sdcard too

The OTA is essentially an upgrade, it builds atop the existing ICS 4.0.4 rom. I had so much mods on top of my rom that I wasnted to have a clean start. Besides, there has been multiple reports of an error 7 in case of non stock or certain moded roms.

Thanks for the tutorial. Thinking of doing the update this way. I have a i9020a rooted with 4.0.4 and when I try to do OTA update I got signature verification error in CWM 5.8.0.2.
For the wipe, from what I understand, you just execute the lock command above which wipes the SD and then unlock it with the second command? Sorry total newbie on this.
That is exactly what i did when the OTA zip pacage first showed up here on xda. Good guide. Im rocking mine with simple kernel
I followed the first part of the guide to restore to stock, and then did the OTA update. It all went well except one little catch: after the OTA update for 4.1.1, I flashed the CWM 6.0.0.7, and then realize that I forgot to copy the root zip file onto SD. Had to reboot the phone and copy the file over. After that I go into bootload mode again and try to go to recovery, ends up with a red exclaim mark and phone is locked. Had to do a battery pull, restart the phone, and then reflash that CWM image, and immediately after that, go to recovery and do the root zip install. Not sure why is that. Have not tried to do the recovery again but I'm glad that I'm now on JB and rooted. Thanks OP !
I keep gettin status 7 error.
When i install the OTA through the phone itself (by letting it restart the phone and install it) i get the exclamation mark.
Im on Stock 4.0.4 and not rootet. Is there anyway to install this OTA without fully wipe it?

The lock command just lock the bootloader, it is the unlock command that will wipe the SD. It will also ask you for a confirmation on your phone's screen...

when you rebooted the phone to copy the su.zip, the OS restored the oroginal recovery. That's why you got the red exclamation mark. To get the CWm, you can flash it again in fast boot, go into recovery and then ask the CWM to reboot.. if it is 6.0.0.7, before reboot it will ask for the recovery to be made overwrite proof (a nice new feature in v6), choose yes and you are good to go..

Status 7 error comes when you have some kind of custom rom or may be some core mod applied to your rom. I am not aware of a way to get this proceed without full wipe: You can try the below though:
1. Flash the stock 4.0.4 for your phone without data wipe (you can wipe the dalvik cache though). This will make sure you are on the "stock".
2. Try the OTA
or you can backup using titanium backup, and then follow my guide. Restore the apps after flashing 4.0.4 and the try OTA.
It will be good it you take a nandroid backup before doing either of the above.

If you have the factory image, from Google (and nowhere else), just run the flash-all.bat file. You "may" have to unlock your bootloader prior to running it if you haven't already, and you'll need to have the device in fastboot mode prior to running the batch file too, but once those 2 simple tasks are done, the batch file takes care of the rest.
If your using a toolkit or some other method for flashing a factory image, I suggest stopping, and just doing the above.
This forum is not for any threads for questions... this needs to go to General or Q/A... just download the factory image from Google, reboot into fastboot and run the flash-all script... you don't need to be unlocked...

same question
I've unlocked & rooted & the OTA fails trying to flash the recovery (trying to flash from twrp, duh, can't overwrite).
How should I go about updating the system w/o wiping out everything I already have?
If I fastboot flash_image system will it only overwrite changes to my system partition & leave my data & apps alone?
I've got OTA Root Keeper installed, so I'm hopeful even if I lose root I can get it back easy enough (either way, no biggie; can always reroot, ain't no thang).
tia for any advice.

That's quite pointless to format everything... But in this case, you can adb sideload the zip from recovery. No need for the file on the sd card.

Only STOCK factory ROMs are flashable this way...
cf. this line from the flash-all.* script for the full factory image of Jellybean 4.2.2.. for 'grouper'.
Code:
fastboot -w update image-nakasi-jdq39.zip
In image-nakasi-jdq39.zip the following files are found...
boot.img
recovery.img
system.img
userdata.img
----
CUSTOM ROMs, however, can only be flashed via a CUSTOM RECOVERY, such as CWM or TWRP.
And as korockinout13 alludes to, it's a trivial matter to FASTBOOT FLASH a custom recovery... and then flash the ROM of your choice.
If you already have FASTBOOT (and your question suggests that you do)... then what's the problem?
Rgrds,
Ged.
The bootloaders of different Android devices have differing capabilities precisely because they are proprietary. Moreover, it is the bootloader that actually implements the heavy lifting of installs etc - the PC fastboot program does little more than send ASCII commands and push blobs of data across the USB cable.
Some Android devices have had bootloaders that understand how to unpack .zip files that contain other types of archives (.tar files, et cetera) but required that the .zip file is placed onto an external SD card using a standardized name for that device. (When the bootloader starts up, it would look for that file automatically). But this was for signed factory bundles, not for arbitrary aftermarket customization. In any event, this doesn't apply to the N7 afaik.
None of these behaviors are standardized though; each vendor decides how it will interpret and respond to fastboot commands from the PC.
The N7 bootloader clearly understands what a sparse ext4 image file is (for use with system.img and userdata.img files) - if it handled them as a pure binary blob, how would it be possible to use the same userdata.img file with 8Gb, 16Gb, and 32Gb devices? Moreover, the N7's "fastboot format" command clearly is capable of creating ext4 filesystems.
So would it be possible to create "sparse ext4" system.img/userdata.img image files corresponding to a custom ROM that could flashed in exactly the same way as the factory image using fastboot? Yes, absolutely. (I've done just that.)
But this is NOT the same thing as taking a custom ROM .zip file (intended to be processed by a recovery using an "edify" script) and flashing it with fast boot; it ain't that easy.
hi,

Better to stick with stock and not attempt to flash custom ROMs if you don't know how to use a custom recovery or toolkit.

Not a big deal. You need to download the factory image for your nexus 7 and find instructions on how to restore with fastboot. That will take you back to factory stock. Or another option is to fastboot flash TWRP custom recovery and use the adb sideload feature within TWRP to flash a custom ROM of your choice. You can find instructions on both of these procedures here at xda or with a simple Google search. Let me know if that works out for you. If you need more help I can give you a hand when I get home from work

Fastboot flash a custom recovery. Then, there are many threads showing how to get the .zip to the device for flashing.

fastboot error

if you're on 23.11.14 you have to go back to 5.0 in order to update to the newest 5.1 (23.16.3).
You can also copy the zip over and flash within recovery, if you prefer. I always think sideload is easier (though actually, now that I think about it, I copied it over and flashed from within recovery myself...)

I had this problem initially as well because I downgraded to 5.0 using the official Motorola 5.0 firmware downloaded from the Motorola website, which is apparently 46-11.11.
I had to use this one-day-older version instead, which is apparently 46-11.10: TMO_XT1095_5.0_LXE22.46-11_cid9_CFC.xml.zip. I found it and downloaded it from here: http://motofirmware.center/files/file/76-tmo_xt1095_50_lxe2246-11_cid9_cfcxmlzip/
So... I downloaded the firmware from that link, followed the OP instructions almost exactly*, and I was able to upgrade from 23.11.14 to 23.16.3 successfully.
* One change I had to make from OP instructions: The pieces of system image had an extra period before the piece number, so I needed to retype those commands like this: fastboot flash system system.img_sparsechunk.0 ...etc.

Thanks! And no, the name is normal. The OTA filename always states the version you need to be on to install it, not the version that it contains.
I recently unlocked the bootloader and rooted my Nexus 6P and just this evening received an update for the November Security Update. This downloads fine but when the phone reboots to install, it just goes to TWRP and doesn't install.
This is most likely incredibly simple and stupid for me even to ask, but is it possible to install one I've unlocked/rooted?
Any advice will be much appreciated.
You need the stock recovery to take otas Thats why it won't work
Sent from my Nexus 6P using XDA Free mobile app
Before, it initiates an update install. It checks root status. If it finds the device is rooted then it stops OTA install, to prevent any further damage to the phone.
In the least number of steps, what is the best way with chainfire modified boot image, and twrp? I love updates, but I loathe having to undo what I've accomplished in the way of customization. I know I'm not the only one who finds it a pain.

If you have gone as far as unlocking and rooting your phone, then you must have decided to go with some sort of ROM. If you do that, youll actually "typically" get the updates quicker from the developer than OTA. Just saying. And you dont lose your mods.
Does anyone have the stock recovery img handy? Should be easy to get OTA's with flashify that way.

The best way to get the ota updates for you would be to download the factory image from Google and Fastboot flash. If you dont wipe user data you should be able to keep most of your settings. You will also need to reflash chainfire's boot Img.

Here is what I do. So long as you do not flash or wipe userdata, this method should maintain all your app data and settings:
1. Download files:
* Latest factory image from: https://developers.google.com/android/nexus/images?hl=en and extract .img files to a folder on your computer with fastboot.
* Modified boot.img from: http://forum.xda-developers.com/apps/supersu/wip-android-6-0-marshmellow-t3219344 and extract boot.img to the same folder (I usually rename it to modifiedboot.img so I have have the original boot.img and modified images in the same folder).
* Latest version of TWRP from: http://forum.xda-developers.com/nex...recovery-twrp-2-8-7-0-touch-recovery-t3234976 (direct link: https://dl.twrp.me/angler/) to the same folder
* Systemless SuperSU from: http://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133 (do not unzip) to /sdcard/download folder on phone
2. Flash .img files using the following commands:
fastboot flash bootloader bootloader.img [using current name of bootloader image - not necessary if no change to bootloader from prior factory image]
fastboot reboot-bootloader
fastboot flash radio radio-angler.img [using current name of radio image - not necessary if no change to radio from prior factory image]
fastboot reboot-bootloader
fastboot flash boot boot.img
fastboot erase cache
fastboot flash cache cache.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot flash boot modifiedboot.img
fastboot flash recovery twrp-2.8.7.x-angler.img [replace x with the current version]
3. Boot into recovery (TWRP), flash SuperSU.zip from /sdcard/download, wipe davlik and regular caches and reboot to system.
Upon reboot, Android will optimize all of your apps, so the first boot will take a while. However, the whole process usually takes me about 20 minutes - perhaps a bit more if I do a TWRP backup before upgrading (recommended).

Thanks. This is helpful, even though it makes me feel like a baby. It's sad, considering we old-timers have been flashing **** that, at the time, seemed more complex. Or maybe it didn't. Never bricked a windows CE device. This isn't really 'complex' anyway. Just feels like far too many steps. I want a twrp flashable image, simply.

Just use a custom rom and update as it gets updated.

Think about that for a second...you would have needed fastboot already to get a custom recovery onto your phone in the first place. You are flashing an entire ROM versus 2 files so it takes longer already. You'll need to update more files on first boot. Not faster or easier so not sure where your argument comes from.

Sorry, but if ya think it's slower or harder to download a rom and flash it, I don't know what to tell ya.
I really just want stock + xposed. So, I should really be looking for flashable security updates. Rooting doesn't necessarily imply that someone wants a custom ROM. *Not* needing a custom ROM to customize the OS is what xposed is all about. Making this choice doesn't mean we are idiots.

Did anyone try this? Did it work? I am rooted but I have stock recovery (instead of flashing TWRP I just booted into it with fastboot for the SU install). Do I still need to flash the stock boot and recovery img's? I'm not sure what changes when SU is intalled. Thanks!
Edit - Does the "full unroot" button on SuperSU work? Is this all I would need to do since I did not permanently flash TWRP?
just did this. works perfectly. all data still there.
thanks!!!
