Nexus 7 softbrick(?) - Nexus 7 Q&A, Help & Troubleshooting

Hi!
I was in recovery, factory reseted the system. I wanted to restart os, but it said "No OS installed", so i booted to bootloader. When i try to reboot to system it says "booting failed". ADB flashing is not working. Please, help me.
Nexus 7
Bootloader version 3.41
I have android sdk installed.

Have you tried using wug's toolkit to revert to stock (and selecting soft-bricked status)? Here's a link if you haven't. http://forum.xda-developers.com/showthread.php?t=1766475
Sent from my Nexus 4 using xda app-developers app

Yep, i tried, theoretically it's fine, but when it says it's finished and device will reboot nothing happens.
OK. Here it is how it now looks: I managed to get recovery working, .zip with rom is on the sdcard. When i try to flash ROM it says "Unable to mount /system"

Update to bootloader version 4.23 then flash the stock factory ROM image.

What command should I use to flash stock .tgz file?

None. You can only flash image files.

Secure boot is enabled on all Nexus 4's, and you cannot disable it. By the way, Secure boot has nothing to do with the lock state of the bootloader -- it has to do with the secure boot chain of the AQP8064 chipset.
Unlock the booloader using "fastboot oem unlock" and then flash the factory images. See here.
If simply flashing factory images, an unlock should not be necessary. Is customer wanting you to try and preserve data?

Thanks for the answer but the wierd problem is that after I unlock the bootloader and try to flash any thing I get":
sending 'bootloader' (2188 KB)... FAILED (command write failed (Unknown error))

and after I reboot it shows that the bootloader is locked
I managed to boot into twrp recovery but no screen by "fastboot boot recovery.img" and I get adb access.
ant thing I can do from here ?

You are seeing a black screen because you are not using the correct command. It should be: fastboot -c "lge.kcal=0|0|0|x" boot recovery.img

cwm can sideload but wipe will give errors (cant mount) and after reboot the bootloader is locked againg and wont boot.
stock just reboots.
can it be HW ? or any other solution ?
btw where did you learend this switch and where can I read about it ? "lge.kcal=0|0|0|x"

Two options before we decide it's hardware.
Procedure #1:
1) Download the LATEST version of fastboot.exe from here and extract it to C:\android.
2) Download the latest factory image from Google's dev page and verify the checksum with what is posted on the website.
3) Extract all the images from all the .tgz, .tar, .zip files within and put the 6 image files in C:\android
4) Reboot your device into the bootloader and plug into your PC.
5) Open a command prompt in that same directory and type the following commands:
Code:
fastboot oem unlock
fastboot reboot-bootloader
fasltboot flash bootloader bootloader-mako-makoz20i.img
fastboot reboot-bootloader
Does that work? If so then continue with flashing the radio, boot, system and recovery images. If not, then go to procedure number 2:
Procedure #2
Follow the instructions in this thread.

6.0.1 - How to flash?

I am looking for a clear explanation of how to flash Android 6.0.1 with root and encryption disabled without wiping data. With all the explanations through the forum, all the "if's" and "but's" get confusing and can be clear as mud. Thanks for your help.
i'm on 6.0 with a stock kernel with encryption disabled and an unlocked bootloader as well.
As far as i can tell you need 2 things.. Flash the System.IMG manually and then we need to wait for someone to post a modified stock 6.0.1 kernel that has encryption disabled too. you can get away with just flashing system.IMG and stay on your older 6.0 de encrypted kernel but I have seen online that wonky things happen when you dont stay up to date on your kernel sometimes.

Where did you find or see this new 6.0.1 modified boot.img that has encryption disabled?
all you need is wugfresh tool kit and go into the Advanced settings and choose to flash individual files. and flash the boot.img to your device.
so flash the 6.0.1 system.img first and then flash the 6.0.1 modified boot.img 2nd.
remember that when you flash anything from fastboot, after the item is finished, the device reboots so you need to watch the device and have your fingers prepared to hold down power and volume down so the device goes back into fastboot and doesnt start booting again on its own.

It's been my understanding that Wug Fresh Tool Kit has been having some issues.
What about recovery, will it have to re-flashed? And what about root?

your recovery should remain as long as oy only flash the system.img and boot.img. you will need to reroot but I cant help you there unfortunately as I am not rooted myself since I need Androidpay to work.
i h avent had any issues with wugfrsh tool kit but if anything you dont have to use it. you can just go to the wugfresh tool kit folder and run the ADB and manually flash with the flash commands manually.

So you don't think I will need flash TWRP after flashing everthing.
I am hoping enough people chime in on how to do this so I can make a clear set of instructions.
I will let you know in a few min.
I just finished flashing 6.0.1 system.img, bootloader.img, cache.img, modified boot.img you posted and the device is at the android is upgrading screen.
if its successful, I will reboot into my recovery which had TWRP previously. if thats good i will let you know.

so I have one problem now.
when My device fully boots up it now says :
"there's an internal problem with your device"
the only reference I can find to this is in regards to the Nexus 9 and flashing the Vendor.IMG file but nothing for phone devices.
any one know anything about this?
I h ave a feeling its because i flashed the stock 6.0.1 bootloader.IMG over my modified bootloader.IMG and I have TWRP installed AND a modified boot.img...
if i could find a new modified bootloader.img for 6.0.1 that would be awesome.
BTW my TWRP is still installed and launches fine.

after you flash TWRP, if you reboot, the system will flash the stock recovery back if its not the original
after u flash TWRP, u need to boot into recovery, and then flash the expected SuperSU.zip

If you upgraded through the regular OTA method or by sideloading, you must be having stock recovery. Now, to install TWRP, you will need the latest image file from here:https://twrp.me/devices/huaweinexus6p.html
Boot your 6P into bootloader mode, and flash using the following command:
Code:
fastboot flash recovery twrp-3.0.2-0-angler.img
As about Systemless/System root, the installer itself goes for the systemless method, and if somehow the requirements fail, it will install to system.

Yes, if you flashed the recovery.img as part of the update you'll need to flash TWRP again. Just use systemless SuperSU.
do i have to compulsorily flash twrp or can i boot temporarily?

You can live-boot it instead of flashing it to the device. Where the filename of the recovery is twrp-3.0.2-0-angler.img, the command would be this:
Code:
fastboot boot twrp-3.0.2-0-angler.img

P9 hard bricked

This is my first time posting on XDA, so sorry if the formatting is bad.
I've tried to root my P9 lite installing TWRP and Magisk, everything went fine, until the last reboot that caused a bootloop.
Trying to fix this I mistakenly wiped the System partition (instead of Data), reading online people adviced to flash the update.zip, when i tried it I had "unable to mount /vendor" and "unable to mount /product".
I tried the update.app method and the eRecovery tool, but still nothing.
I read that the problem was probably caused by en error in boot.img or recovery.img, so i extracted those files from the firmware and flashed them using TWRP. By doing so i deleted TWRP itself leaving me unable to flash system.img.
I tried to flash it using fastboot, but every time i try to write a command regarding flashing i get a FAILED (remote: command not allowed).
Now i have a bricked phone, i can access fastboot but it doesnt seem to be working. I cant access adb since i can't access the recovery (at least i dont know how to ).
Any advices?

hey guys
i have the same problem, had rr marshmallow on my p9 lite and tried to flash the new recovery for nougat by old droid. since then i cant enter nowhere without fastboot. phone unlocked and frp unlocked. does anybody have another idea. flashing stock recovery did not work, flashing twrp did also not work. need more ideas, erecovery and dload method do not work, i have acces to fastboot
Try to flash the correct oem.info.I've had the same problem with my P9(EVA-L09).

Brick (error mode) after update_command: only fastboot works.

Hello I wanted to install Oreo on my PRA-LX1 following this guide
https://www.haky86.com/2018/05/12/install-emui-8-0-huawei-p8-lite-2017/
I was on official EMUI Nougat firware, I downloaded LX1C432B322 of 2018.04.13 what he said, installed nocheck recovery and then update_command. Reboot, title, nothing works except fastboot. I re-unlocked the phone with oem unlock and after reboot same.
I tried to flash twrp-3.2.1-v3.5-prague.img again to fix but length error with "fastboot flash recovery"
I tried to flash his OreoTWRP.img with "fastboot flash recovery_ramdisk" and it pass, reboot but I can't boot to recovery.
Pressing VolUp + Power does nothing, "phone can't be trusted" screen with the eRecovery option (VolUp for 3 seconds) but eRecovery is dead (error mode)
Maybe this OreoTWRP worked but how to bot to recovery now ?
please help I can't buy another phone it's urgent...

I'm not responsible of bricks caused by people since most of them not follow the steps I wrote.
@haky 86 (I'm assuming you were the one who wrote that guide) is the guide for updating from nougat to oreo or updating an Oreo firmware to the latest?

This is I want to know. He don't said it but I tried to flash oreotwrp from nougat and it said partition error using recovery_ramdisk. And the nocheck didn't work, so I took another nocheck for this TWRP and put the update_package command and then this
I just update my guide, the sample I wrote it was emui 8.x because I'm already at oreo. but procedure is same the only thing change is recovery, on oreo called Recovery Ramdisk on nougat called just recovery, please check the updated article here the screenshot.

Download the nougat rom you were on before. Extract update.app to get the recovery. Flash it using fastboot. Then try dload method.
Or flash nougat twrp and try flashing the nougat rom via HuRUpdater

I can't flash recovery from update.app of nougat rom. It say partition length error. recovery_ramdisk say partition error...
Can I flash the system.img ? There are fastboot.img in the update.APP. Can I flash recovery after flashing fastboot ?
I need to be sure because if I flash fastboot and lost it my phone will be really dead

This forum is called xda-developers but there are no developers or someone who really know how android works. I can't found anyone who can help me even on other forums. I have access to something which can save my phone but NOBODY know how to use it. How disapointing.
