There are two STOCK 4.2.2 roms in this thread. One is DEODEXED and the other is ODEXED.
I recommend downloading the DEODEXED STOCK 4.2.2 rom.
Here's the link to the DEODEXED STOCK ROM:

Download it, put it in your N7 and flash it via recovery. You won't lose any data and you don't have to wipe anything. Just flash and go!

I won't get error 7 ?
For installing this ?
And its not ota update how come it wont wipe data?
Sent from my Nexus 7 using Tapatalk HD

1) make a full nandroid (cwm/twrp) backup
2) flash a 4.2.2 stock-derived ROM on top of existing ROM - no wipe
2.5) flash a minimal root kit (SuperSU or Superuser) if not in ROM in step 2 - no wipe
3) flash the same kernel you used previously - no wipe
4) profit!
No workie? Restore backup from step # 1 and try something else.

1. Have you read the thread?
2. No it won't give you an error. Why would it?
3. It's from the official OTA update. You just don't need to wipe anything. Trust me on this.
4. How come? I did this last night on my Nexus 7 and everything is just fine.
5. You won't get a bootloop or an error if you do exactly what I just told you.

There's no need to do that. But in spite of it, I can tell you that you can just create the nandroid backup and leave it in your device. Don't pull it out. Just flash the download in my previous post and if anything goes wrong. Enter recovery mode and restore your system. Even if you did pull the nandriod backup file from the N7 and the device fails to boot up, you cant just put the file back in to restore it that way. It won't mount so you can access the internal storage system.
P.S i don't know how to make the backup show up but i think there are a few thread here that some people have found a solution to it.

I have had TWRP behave the same way - sometimes it will put backups in
/data/media/TWRP/...
and sometimes in
/data/media/0/TWRP/...
It is a bit of a mystery what causes this to happen. Strangely, when there is a folder in the first location, TWRP (2.4.1.0) will not find the second one. But, if I manually move the files from the first location (/data/media/TWRP) to the second location (/data/media/0/TWRP) using a file manager, then TWRP will find the backups no problem.
well, the "sdcard" mount point ( == /data/media/0/ ) is the thing that shows up on the PC via MTP mode, so I would just move the files to the second location. I'm not sure if CWM behaves the same way, but you will certainly be able to copy them from the N7 to the PC at that point.
good luck.

LOL. I told you it works.
There's one thing that you're missing from that update. And that is the bootloader version, the bootloader version that you're currently using is 4.13. The newest version is 4.18. You don't have to update it if you don't want to.
I'll include this link for you to flash the latest bootloader via command prompt.

Updating bootloader does not wipe anything. It simply replaces and updates the one you already have on.
Definition of a bootloader:
http://m.androidcentral.com/what-is-android-bootloader
Sideload? I think so.

boot(basically kernel) and system are usually what people mean 'custom ROM'. So if you just manually flash these two things(and usually need to be done together), none of your 'data' would be lost.
So just find these two images (usually .img) in whatever custom ROM you want and flash it.
This is the unix convention for a long long while and android is just linux

Question about flashing updates on a rooted phone

I have a rooted 6P running the stock rom on the February security update with a bunch of Xposed modules and the Franco kernel. I know I won't get OTAs this way. Can I just flash the March security patch (MMB29V) and do nothing else? Or do I have to wipe data or factory reset? Do I have to do anything with the Franco kernel?
For the future, what would I need to do to flash Android N when it comes out on my rooted phone? Thanks a bunch!

Most likely you cannot. An OTA update will do a check on your system and see that you have modified things and terminate install. You can leave your data alone but you will have to flash your boot and system partitions with the factory image

Don't flash the entire factory image or you will lose data. / only the boot and system images to their respective partitions. Once you complete that you can Flash the OTA update zip file and you will still have your data you can extract the boot and system images from the main factory image you download from Google using WinRAR

It's easier to just flash all of the images (except userdata) top to update, rather than flashing two and then messing around with OTA.

So is there anyway to flash the update without losing my data/apps??
Thanks!

Yep. Probably would be a good idea to wipe data and the caches in TWRP first.

i used fastboot to install march update on my nexus 6p but now when trying to install twrp through fastboot it during writing it says permission denied. why is this?

Can you provide a screenshot of your attemp to flash the recovery? Also you might want to try opening the command prompt as administrator, right click on the command window in start menu and select open as administrator.

Not at all a good idea @Heisenberg, as I just experienced. We were talking about keeping the apps and system as it was. Just wiped data and got an hardreset.
Clear cache only.

Where did you say that? I know that wiping data will remove apps, but it's the right way to go about it to ensure no problems occur.

Surely you were aware that wiping data was going to remove your apps? So all you needed to do was back them up first and restore them after you flashed. Apologies if I should have made that clear in my previous posts.

No problem. It was my stupid mistake.:good:

fastboot flash bootloader bootloader-angler-angler-02.45.img
fastboot reboot-bootloader
sleep 5
fastboot flash radio radio-angler-angler-02.50.img
fastboot reboot-bootloader
sleep 5
fastboot update image-angler-mmb29v.zip
Normally in the last line there is an option "-w" this wipes the data.
Don't do that and modify the script so the option is gone, like I did.

Uh, my phone just downloaded a system update of some sort, but I haven't installed it. Is this supposed to happen on a phone that's rooted and on the stock ROM? Can I install it safely or should I still flash the factory image instead?
And @Heisenberg, in your guide do you type in all the fastboot commands at once or do you do it line by line? Thanks again, your guide is super useful for rooting noobs like me :thumbup:

Don't install it, it'll fail, you must flash the factory images. Each command is entered individually (press enter key to send the command), wait for flash to finish then enter the next command.

Bootloop Help After Trying To Root 7.1.1

So I flashed the 7.1.1 update and everything was fine. I then tried to root through TWRP with the most recent version of recovery and and SuperSu and when I went to reboot it would get to the "Google" splash screen and go back to the warning. I then tried to restore to my Nandroid that I made right before the 7.1.1 flash but it does the same thing. I ended up doing a factory reset, still looping. I tried flashing an old firmware but it still would loop. I got desperate and did a full wipe and then flashed the old firmware from September's update but it still will not boot. I'm a long time lurker I just don't post much. Any help will be appreciated. Thanks in advance!

Well if you cant access twrp then your not flashing anything; did you try downloading the latest Nexus 6p factory image and using adb to flash it?? If you need help with that I can lay it out for you. Also there was an efs partition issue with twrp 3.0.2-1 and down so make sure your twrp is 3.0.2-2!

Make sure your using twrp 3.0.2-2; and download the latest factory image for the Nexus 6p (NBD90X) and use adb (fastboot) to flash that whole thing. Extract the files to your android sdk platform tools folder then run the flash-all.bat file. (If you are using a 64gb or 128gb device DONT DO THIS) Only do this with the 32gb model.

Newest image didn't work either..

Have you tried WugFresh's Nexus Root Toolkit? Not sure if it will work for your situation, but it has an option to restore to factory settings and unroot if you're soft-bricked or bootlooped. Might be worth a shot if everything else isn't working.

FWIW, I successfully updated to 7.1.1 NPF10C and rooted by using fastboot to flash bootloader, radio, boot, system, and vendor. Then used TWRP 3.0.2-2 to flash SuperSU 2.78 SR1. No issues.

Just flash the vendor image to the corresponding build. Ex: build NBD90X needs the NBD90X vendor image and so on. Should resolve the issue.

Fastboot just says to connect a USB Cable but it's connected. I have drivers installed. I don't have a rom obviously to enable USB debugging -_-.

If u have TWRP just boot to recovery then plug in the phone to computer and a window will pop up showing Internal Storage and jus copy a ROM/Gapps/Vendor to Internal Storage and then select Install and flash away.

Hi guys,
I have a honor 6 plus (PE-TL10), it was running EMUI 4. I flashed TWRP 2.8.7 and then wiped all partitions through it(cust,system,etc) then flashed stock recovery back, now i am trying to install EMUI 4.0.1(Android 6.0) via 3 buttons Huawei update but it stops at 5% and fails. Can you guys provide me with any help, I really need it.
Also now when i am trying to wipe data thru stock recovery i get an weird error message at almost 25% saying "reset balong modem setting fail", which making it more difficult to get back stock rom.
Just last question; the Unbrick option in the "HONOR_6_and_6Plus_Multi-Tool", wil it restore the device to stock rom and fully functional state after that or it will miss some parts of the stock rom ?
Many thanks and regards

For you to restore to stock you need to flash boot, recovery, system and cust.
Make sure you have stock boot and recovery to for forced update (3 buttons).
What happens in most of the cases is boot and recovery files are corrupt.
I would try the unbrick of the Multitool. If it fails, I would flash manually all img files for each partition. But using the same firmware version as the last installed one.
Post your results and I will try to help.

1:Extract the ROM with huawei update extractor
2:download latest minimal adb and fastboot drivers and install them
3ut the extracted system.img,recovery.img,cust.img,boot.img and userdata.img into the fastboot.exe folder
4: boot into the fastboot mode
And finally flash the above mentioned imgs one by one with this command
fastboot flash XXX XXX.img
After flashing files type
Fastboot reboot
and every thing should be fine again

Thank you for answering, I did used Huawei MultiTool and Unbricked my device. I flashed four img files(SYSTEM,CUST,RECOVERY,BOOT) and now i am back to stock rom and running smoothly.
I tried to use force update feature on my device after that but again i got the same result, it stopped at 5% and failed. I guess i will keep it the way it's now.
Many thanks; you guys are awesome!

Thank you, I did that except for userdata.img file, the Huawei MultiTool only mentioned 4 files(system,recovery,boot,cust). Now my device is running back again on stock rom. Should I flash userdata.img file or is it ok?
Just a question that i keep asking myself; inside the stock update.app file there are 22 img files, what do they do? I only flashed four of them so what purpose do the rest serve as? if the device can operate fully functional with four of them!
Many thanks,

Don't use any other img file. And don't flash userdata.
If it works, don't change it. ?

Got similar issue on my honor 6. Can't update via SD card method or 3 button after leaving developer preview. Not even OTA updates install. All fail at 5%. So I'm stuck on B830 for now. Will try for a solution later.

None. Just errors in software update/upgrade. Right now I'm looking into testing different stock recoveries.

There's no other solution, either stock img files or some sort of transitional package.

Stock is a no go for me. I'll try transition package next. Maybe only just the recovery. Might work for the OP as well.

Same issue with me as well please help me in this case.

For you to restore to stock you need to flash boot, recovery, system and cust.
Make sure you have stock boot and recovery to for forced update (3 buttons).
What happens in most of the cases is boot and recovery files are corrupt.
I would try the unbrick of the Multitool. If it fails, I would flash manually all img files for each partition. But using the same firmware version as the lasthttps://cdn-cf-3.xda-developers.com/images/smilies/frown.gif installed one.
Post your results and I will try to help.
