[Q] just flashing radio/boot/system image for 4.2.2 ? - Nexus 7 Q&A, Help & Troubleshooting

running TWRP and rooted 4.2.1 N7 3G and not wanting to lose any user settings.
Is it ok to just unzip the factory image and flash the radio/boot/system image via fastboot ? I know i would lose root and any mod to the system but that is relatively simple to re-apply
alternatively, i would need to flash the recovery image and manually undo changes to system in order for OTA to go through.
anyone see problem with this ?

Yep, that's fine. I fastbooted the bootloader/radio/system, all was well. Definitely fastboot for the radio, can do the others in recovery if you wish.

I'm a nervous noob.

This is a pretty specific question and i'm not sure this is the correct place to ask this but i recently installed the stock rom (Via Zip) on this thread: http://forum.xda-developers.com/showthread.php?t=2527806 . I flashed just the rom NOT including the bootloader (Because i don't know what it does) and the .97 radio because there seems to be some issues with it. Now, everything is working perfectly as it did before. What i'm wondering is after today's random new 4.4 factory image and ota update from Google (I think its krt16s); i know they are probably going to compile a flashable zip, and if they do what exactly do i need to do?
I'm extremely weary when i do these kind of things, the last time i flashed any sort of rom was on my OG RAZR. Would i have to install that new bootloader? (Also what exactly does it do) And would i have to wipe?
I can make the radio judgement on my own but i'm just not entirely sure.
If anyone could answer my questions that would be wonderful, i'm also sorry for posting this here, i'm not allowed to post in that thread because i'm "new" to the site.
Thanks!
you dont have to sorry as you are in the right section for asking questions.
You can either wait for a day or two for someone to post a flashable zip file. If someone do post it; all you have to do is copy it to your phone. Reboot to recovery mode; make sure you have cwm recovery installed. From there choose "install zip" > install zip from sdcard, choose the flashable zip. Once it finishes installing, clear cache partition and reboot. You will not lose anything in the phone.
If you want to install the new krt16s stock update. First, copy all of your files (pictures/music/data etc...) to your computer. This will wipeout everything. Download the image file. Open it with winrar or 7zip. Extract all the files to a folder. Connect your phone to the computer and reboot it to bootloader. Run the "flash-all.bat" file from the extracted files. Wait for it to finish. It will update everything (kernel, bootloader and the new 4.4)
You should know what something is before flashing them wildly, that's the easiest way for people to brick their phone by flashing something incompatible with their devices. Bootloader is the main program that boot first when you turn on to phone to make selftest and boot normally into the operating system kernel, with Nexus you can use it boot into recovery and flash images to partitions as well. It's very recommended to update it along with new Android version or you may run into issues. You should already know this since you had to access the bootloader screen to boot into the CWM recovery.
Stick with using CWM for now and flash the flashable zips. Just make a full backup of your device you can always restore it later. Just know that unless you flash radio separately (aka baseband), roms generally and should not come prepackaged with the baseband, so it is not affected when you flash a different rom, you have to upgrade it manually.
When you flash a new Android version, usually its recommended to do a factory reset in your recovery to avoid issues.
Installing factory image takes a few more steps and required using fastboot, but if you want to check the link in my sig. Also I recommend switching to TWRP recovery, but that's just me.

I see, me personally, I'm not very fond of using adb; I haven't used it at all prior to yesterday. I may try this out, but should someone post the new kernel, boot loader, 4.4 and radios would that be the same as flashing the factory image?
This probably seems like a really stupid question but I wouldn't be smart to try to download the ota directly from the phone (via check for updates) would it?

You need to learn to use adb and fastboot if you want to be able to do advance things with the phones, or just avoid flashing too much, because once you run into trouble (especially due to using toolkits), you will not know how to recover your device.
If you want your device to be stock and able to receive OTA updates, in addition you also need your stock rom to be an "odexed" version, some roms are "deodexed" which will not receive OTA. You also need to have stock recovery, which CWM isn't.

Thank you! One more question, let's say I revert back to my nandroid back up. I backed my ROM up on Android 4.3 rooted and unlocked with CWM. If I flashed the 4.4 factory i image what exactly would happen? Would I boot into 4.4 absolutely stock? Or would I end up with 4.4 unlocked etc...?
Thank you for the help I really appreciate it. ☺

When you flash factory image (using fastboot method), it will wipe your entire device and all user data, and you will boot into stock. Except if you do it manually you can prevent datas from wiping, follow these steps and pay attention to the red texts.
Sometimes apps data from older version can cause issues with newer version though, so a clean install is always best.
But if you have custom recovery, you can flashable stock roms, such as this one by fireb33, it's essentially the same as stock. Get the "odexed" version which is required to get OTA updates. Some peolpe say they can get OTA with custom recovery, but I have never tried that. The safest bet is to use fastboot to restore to stock recovery. You could also use custom recovery to flash OTA update packages to update versions that way.
As for backing up, people tends to call the backup "nandroids". After you do backup, if you're doing something that required the device to be wiped, you need to copy the backup to your pc. The CWM nandroids are usually located in 'clockworkmod' folder, but if you don't see it, search in "/data/media". I do not use CWM so I don't know what it allows you to back up, but generally "boot" (which is the kernel), system, and data partitions. It will not restore everything to stock such as your radio (baseband) or recovery.
I highly recommend switching to TWRP recovery, it will make flashing a lot easier.

[Q] stock rooted Lollipop OTA fails?

All,
Thanks in advance for any help you can provide. I have a Nexus 4 that I rooted and installed CWM recovery on, but I never installed any new kernels, ROMs, or radios. I'm currently on 4.4.4 and I want to upgrade to Lollipop. The OTA upgrade failed. So I tried returning to stock recovery and doing both the OTA and adb sideloading the OTA zip. Both fail.
The error message is "Package expects build fingerprint of google/occam/mako:4.4.4/KTU84P/1227136:user/release-keys or google/occam/mako:5.0/LRX21T/1576899:user/release-keys; this device has google/occam/mako:4.4/KRT160/907817:user/release-keys." (But I definitely have 4.4.4 on my phone, not 4.4.0.)
The extra difficulty is that I really, really do not want to wipe my phone. I have a lot of apps with a lot of configuration and other user data. So is there anything I can do? I guess I should try unrooting somehow? Or is there some other zip I can download that, through some type of recovery, will install the OTA without doing this check and also without wiping me?
Thanks again!

OTA wants complete stock and obviously it doesn't think so about your phone. One option could be to back up to the cloud or some place outside the phone with TiBu (or whatever backup app you trust), then flash lollipop and try restore from TiBu. Another option would be to unroot (Supersu has an option to completely unroot), then retry.
Actually, I figured out what works! This was on a stock rooted device with stock recovery, but I bet it would work with custom recovery too. Instructions modified from https://pay.reddit.com/r/nexus4/comments/1qny3f/howto_update_your_stock_w_lte_nexus_4_without/ .
1. Download the image you want from https://developers.google.com/android/nexus/images . Extract it, extract the .zip file inside it too, and collect all of the .img files into one folder.
2. adb reboot bootloader (and wait until the bootloader comes up)
3. fastboot flash bootloader bootloader-mako-makoz30f.img (or whatever file has a similar name, if you got a different image than I did)
4. fastboot reboot-bootloader (and wait until the bootloader comes back up)
5. fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1701.04.img (or whatever file has a similar name, if you got a different image than I did)
6. fastboot reboot-bootloader (and wait until the bootloader comes back up)
7. fastboot flash boot boot.img
8. fastboot flash recovery recovery.img
9. fastboot flash system system.img
10. fastboot format cache
11. fastboot reboot
12. Don't panic unless you've seen the startup animation for at least 15 minutes without anything else happening.
I lost root, but I imagine re-custom-recoverying and re-rooting won't be any harder than the first time around.
Hi moriarty00,
I'm going to try the same procedure, thank you for posting this.
Can you confirm that your data and app are safe after the upgrade?

Wow, a 12-step program
I simply rolled back my changes, and applying the OTA was as simple as pressing the "restart and install" button Here are some steps:
I used the app Flashify from Play Store to flash stock 4.4.4 recovery. I downloaded the stock factory image from google's own site (this one), used 7zip to extract the archives (tgz and tar), found "recovery.img" and transfered that to my phone. Then chose that file in Flashify.
Uninstalled all apps that made system changes, like Xposed framework and mods, BetterBatteryStats etc.
Removed Root with SuperSU cleanup function
Rebooted for good measure and apply OTA from notification - wait an hour or two for it to complete
Profit (do we still say that on the internet? Getting old here...)
I don't know if certain ways to get root will break the OTA. I used towel-root, and apparently SuperSU was able to undo that completely.

Yup, perfectly safe! Just make sure not to flash other images, like userdata.img.

Unfortunately the steps did not work for me, maybe I had some irreversible modifications or I had followed a different rooting procedure.
Or maybe I made a mistake in the upgrading steps.
Anyway, I had to flash the whole ROM and now everything is working fine.
Hey!
Basically I have similar problem with upgrading from 4.4.4 to 5.0 using OTA. Log from TWRP says:
Package expects build fingerprint of google/occam/mako:4.4.4/KTU84P/1227136:user/release-keys or google/occam/mako:5.0/LRX21T/1576899:user/release-keys; this device has google/occam/mako:4.3/JWR66V/737497:user/release-keys.

Phone has been rooted using Nexus Root Toolkit. And as long as there wouldn't be a problem with flashing using adb and wiping all data, there is one setback... My nexus is somehow broken. Communication via USB does not work, at all. Neither phone nor PC sees other device. Certified LG service centre nearby said that it is problem with main board, so generally repair is unprofitable.
So question is: How do I update to 5.0 and then root, without USB connection to my PC?

[Q] Issue sideload 5.0.2 OTA - /system/bin/install-recovery.sh has unexpected content

I'm trying to apply the 5.0.2 OTA on my wife's Nexus 7. When I try and sideload the OTA, I get this message:
Code:
"/system/bin/install-recovery.sh" has unexpected content
It was rooted previously so inside Super SU, I used the 'full unroot' option then tried to apply the OTA again. Same results. I also made sure to reflash the stock recovery in case that had anything to do with it (I was using WUG toolkit which was booting into stock recovery, but just in case...). Same results.
I've seen other reports of applying just the system.img file from inside the factory image. (Here and Here)
Is that a solution that would work for me? Is anyone else having this same issue and has a solution for it?
I could do a factory reset, but thats sortof a pain in the butt I'd like to avoid if I can...
Thanks,
Zeustopher
I've always used fastboot to flash boot, recovery and system then adb sideloaded the update zip and never had an issue nor have I ever lost data.
Looks like you definitely need to flash system since that's the error you're getting. It takes seconds so why not do it.

Same issue. Worked for me.
Pretty sure it is because 5.0 checks the entire system partition rather than pieces, so simply being rooted will cause to fail because there will be a mismatch. Pretty sure if you go the OTA root, you have to flash back to stock and unroot before you can update without failing. I would just flash the images directly in NRT or using ADB, and you should be fine.
I followed this method and it worked like a charm for me.
http://www.reddit.com/r/Nexus5/comments/2psomc/
Manual option
I flashed the boot.img and system.img matching the current version on our tablets (extracted from the factory image) and after that the OTA update works.
Made a backup just in case, but did not need it as all settings and data were preserved.
I'm guessing the return to stock does something similar (maybe a couple of things extra)

[Q] NEXUS 4 Wont Update to Android 5.0.1

Hi,
I have a rooted Nexus 4 with android 5.0 lollipop build LRX21T.
I have TWRP recovery installed version : v2.8.0.1
The device id rooted via placing the zip file in the device and flashng it via TWRP recovery.
But i am not able to update to android 5.0.1 via google OTA update.
Everytime i try to install the 5.0.1 OTA it goes to TWRP recovery.
I found that the downloaded OTA update file is placed in /cache folder , so i try to update it manually but failed as it shows some update partition error.
"E: error executing updater binary in zip '/cache/e93b********************.signed-occam-LRX22c-from-LRX21T.e93b****.zip"
update partition details.....
I think i am getting this error because the device is rooted.
Can someone guide me how to update my device..and if this because of the rooted device how to unroot without going back to stock.
Thanks in advance....
You can't flash the ota in twrp. You have to be 100% stock recovery, system, kernel, and radio. Flash the stock recovery with fastboot then try the ota.
Sent from my Nexus 9 using XDA Free mobile app
I flashed the stock recovery the OTA update continued in the stock recovery , then it showed a error....and i had to restart the phone ...now the ota update has disappeared with the phone still in android 5.0 ...Can you tell me how to get the OTA update back...?
1)Does the error came because the phone is still rooted ?
2) If so how do i remove the root with returning stock .?
3) also if i root and return to stock will it wipe my phone apps and their data...
Now i got the OTA update downloaded manually on my laptop and and booted into stock recovery to try to sideload the zip it gave me the error
"package expects build fingerprint of google /occam/mako:5.0/LRX21T or google /occam/mako:5.0/LRX22C user release keys; this device has google/occam/mako:4.4/KRT160 user release keys .....
This is weird as i am running android android lollipop 5.0 LRX21T and not android kitkat....

Try flashing factory image.
The OTA will flash only on the stock recovery it won't work in any modified/custom recovery. So flash stock recovery first then you are good to go.
Edit: You may also try flashing the factory image, u may lose your data while doing that
Head to https://developers.google.com/android/nexus/images and download the latest image, flashing procedure is explained there too.Its not compulsory to lock bootloader afterwards BTW, its personal preference.

Actually i dont want to flash stock as i will lose all the data in the process....
Any other way....?
If there is no other way could you please suggest any tool kit which will backup all data including sms ,contact, call logs and all app data and /data/media folder. in one go ...?
use advanced backup from twrp backup menu and select data only to create a nandroid backup of data only
you can also use titanium backup to backup to choose what to backup and restore it afterwards but it will need root again.
sync your contacts with google server
Flah rom in fastboot
Download factory image, flash system, bootloader and recovery manually. You won't lose your data.
You need stock recovery to proceed flashing the OTA, custom recovery won't flash the OTA, i don't think being rooted is the issue Just flash the stock recovery to solve the problem.

Rooted IS an issue. You can't be rooted and apply the OTA file, it will fail every time. As a previous poster has said, the phone MUST have stock bootloader, recovery and be not rooted for the stock OTA's to apply. If they see any modification during the process, they abort. It's been discussed many times.

thanks for pointing out i was so wrong

OTA path

Does anyone know where is located the downloaded OTA?
yes but you need root
its in \cache
i have the update also but cant flash as i loaded the twrp recovery image and only stock recovery can run the ota

Thanks. I couldn't find it, so I updated and now I lost root...
Strange isse, before OTA update (I have stock recovery) I wanted to NAND backup through TWRP boot, but phone wasn't found by fastboot neither adb... So I updated without backupping. Now too phone isn't found by fastboot, so I cannot neither root!
USB debug is on like always, I already tried to disable and enable again, but no way
