[Q] Fastboot.exe Crash Nexus 7 2013

I have not had a lot of experience with SDK tools like adb and fastboot, but I have used them to Root my Nexus 7 (2013) with no problems. But now I am not able to update my Nexus from Kit kat 4.4.2. I have had no problems updateing before, and have not had problems rooting after updating. But when I try to update via the OTA update, it fails every time. I had the TWRP Recovery, and had no problems updating. When this update failed I tried useing the ClockworkMod recovory, but the update also failed. I tried to manually update useing the downloaded razor-ktu841.zip, and the platform tools fastboot. If I run the flash-all.bat, it will write the bootloader, and then restart the bootloader. After that Fastboot.exe crashes. I used Fastboot to flash the stock recovery for my device, and that worked flawlessly. But again, both the OTA update and updating manually failed. If I try to just update useing "fastboot -w update image-razor-ktu84l.zip" Fastboot.exe also crashes. I would leave my Nexus on 4.4.2, but I am having occasional issues with the touch screen, and frequent problems with the Gyroscope and Accelerometer that I hope will be fixed by updating. They will just stop working, and only a restart fixes them. I am compleatly stock as far as roms go. I stuck with stock android. I also believe I have the stock kernel as well, seeing as how I never touched it. I would rather not factory reset my tablet, because I have a lot of stuff on it. That would be a last resort for me.
Any help would be much appreciated.

I can't actually find a KTU841 zip on the Google Devs page, also stock images from said source are typically not .zip files, they are .tgz images. (https://developers.google.com/android/nexus/images). The reason you can't OTA update is because you rooted your device, once unlocked and rooted you need to sideload updates manually, a small price you pay for wanting that bit more.
To me it sounds as if a factory reset may be your best option in this case, that is certainly what I would do at this juncture. You can still connect your device to your computer and back up all your stuff before you wipe it though.

Sounds like you need to reinstall/update the SDK. You're missing a .dll or something. I know I have in the past deleted more than what I should have when cleaning out the platform tools folder after flashing images. If you run the flash-all.bat it will COMPLETELY wipe your device including whatever is in storage. You can modify the flash-all.bat with a text editor and then be able to use it without it doing a complete wipe. Open the flash-all.bat with notepad (I use editpad lite) and remove the -w from the text. Removing the -w will keep the flash-all.bat from flashing the userdata.img which is inside the image zip which is what wipes the device. The flash-all.bat will flash the stock recovery so any custom recovery will have to be reflashed if you use the bat file. Personally... after fixing your sdk install I would pull the boot.img and system.img from inside the image zip and put those in your platform tools folder so that you can fastboot flash them. Download a custom recovery (I use TWRP) and rename it to something shorter, put it inside your platform tools folder so that you can fastboot flash it also. Download the supersu installable zip and put it in your device storage. The bootloader image does not need to be flashed because it has not changed from 4.4.2 to 4.4.4.
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery twrp.img
Use the buttons on device to boot into recovery. Install the super su zip. Then go to advanced wipe, wipe cache and dalvik. Reboot system. "IF" you run into any problems after updating you can do a factory reset from inside TWRP and it will not wipe your storage. Of course, doing a factory reset from your devices Settings/Backup & reset will wipe everything.

The OP was correct. If you unzip the tgz far enough you will see:
bootloader-flo-flo-04.02.img
flash-all.bat
flash-all.sh
flash-base.sh
image-razor-ktu84l.zip
Inside image-razor-ktu84l.zip you will see the rest of the images:
android-info.txt
boot.img
cache.img
recovery.img
system.img
userdata.img
Being rooted will not prevent you from being able to download and use an OTA like you can if not rooted. It's what you do after you are rooted that will make an OTA fail, a lot of the time even if you sideload it. Custom kernels, ANY mods to system files can and usually will throw an unexpected contents error or some other kind of error. The smaller the OTA is the more likely it will work, I wouldn't count on it but it is possible. If there are no modified files that the OTA is trying to update the OTA could work. Fact is, a couple of the KitKat updates were VERY small and I was able to get the OTA to work just fine (without sideloading) and I use a custom kernel, recovery, hosts file, media_profiles.xml, fonts, bootanimation and ui/audio sounds. I almost always fastboot flash the needed images separately but for grins tried those two small OTA's. Rarely do I even bother with an OTA.

Works!

Thanks for your help, after re-downloading the SDK, and image (just to be safe) I was able to flash the boot, system, and recovery with no problems. It upgraded me to 4.4.3! I then was able to do an OTA update to 4.4.4 and then rooted it by installing the SuperSU installable zip with TWRP with no problems. Thank you very much!

[ROOT] N5206 v150108 - v150312 root method with working wireless

Even simpler root than Invisiblek's method for the older versions: If you have already tried that method and now have broken wireless, see Post #2.
Note: A more detailed and user-friendly version of these instructions can be found at: http://www.oppoforums.com/threads/n5206-international-root-instructions.24159
Download http://lum.uk/n3/files/recmodn3.img and http://lum.uk/n3/files/Root_ColorOS_by_tantrums_v2.zip
Copy the rooter onto your SD card.
Boot into fastboot by holding volume up while powering on the phone.
fastboot oem unlock
fastboot flash recovery recmodn3.img
fastboot boot recmodn3.img
Flash the root coloros zip file, reboot and you're rooted.
Note: This is a modified stock recovery that can flash OTAs as well as zips not signed by Oppo. If you prefer TWRP then that is available here: https://dl.twrp.me/n3/. Note that at the time of writing TWRP is unable to flash OTAs.
Thanks to [email protected] for the original root method, Arvin A. [email protected] for the fixing SuperSU to work on ColorOS, and [email protected] for providing the modified N3 recovery.

Restoring stock firmware
Download your chosen firmware and recovery from this thread
Copy the firmware to the root of the internal storage
Take a nandroid backup using TWRP
Reboot to bootloader from within TWRP
Code:
fastboot flash recovery recovery_N3.img
fastboot reboot
adb reboot recovery
Use the stock recovery to flash your chosen firmware
If you are downgrading then wipe data and cache (you did remember to take a nandroid, right?)
Reboot
You are now on stock fimware. Follow the rooting instructions in post #1, and if you wiped you may optionally restore only the data partition from your nandroid backup.

Will memory be erased?
Hi,
So i'm looking forward to root my beautiful Oppo N3.
On my last Phones memory (data and so on) was erased alongside with unlocking the phone.
Will it be the same on this phone so that I have to backup all my data?

Your data will not be erased when rooting or unlocking. Also your warranty will not be invalidated like it is with other manufacturers.
It is, however, always wise to take a backup before anything like this, just in case something does go wrong.

Hi,
I tried rooting my N3 now but i made a mistake by not executing the commands after falshing SuperSU.
That's why my phone is always booting into TWRP. There i tried executing your commands, but apparently the shell refuses to su by throwing exception: "command not found"
Going on with mount-command, it is also giving back an error: "can't find /system in /proc/mounts"
Hope sb could help me now...
EDIT: Solved by installing stock recovery, booting system, and the reflash twrp.

Download http://teamw.in/project/twrp2/282 and http://download.chainfire.eu/supersu
adb reboot bootloader
fastboot oem unlock
fastboot flash recovery openrecovery-twrp-2.8.4.0-n3.img
fastboot reboot
adb reboot recovery
Flash Super SU from within TWRP. Then boot the OS
adb shell
su
mount -o remount,rw /system
echo "/system/xbin/su --daemon &" >> /system/etc/init.qcom.post_boot.sh
Reboot and you're rooted.
By default ColorOS doesn't let apps auto-start themselves, so go into security centre and allow SuperSU to auto-start, otherwise you won't get prompts for root when other apps need it.
Thanks to invisiblek for the original root method and babelmonk for the fix. I have shamelessly copied these and adapted them for the new firmware.

Quoted from your post in oppo forum
Wait for the phone to boot:
adb reboot recovery
It should boot into TWRP recovery flash the SuperSU zip you downloaded but do not reboot as we need to fix a small bug in SuperSU due to Oppo not using the expected startup scripts.
adb shell
su
mount -o remount,rw /system
echo "/system/xbin/su --daemon &" >> /system/etc/init.qcom.post_boot.sh
Reboot and congratulations. You are now rooted.
Sorry , quite new in fastboot command so i apologize if I misunderstood you but I'm running on N5206_EX_23_150208 , which should i follow ? to boot up after flashing SuperSU or not to boot up ?

It doesn't matter which way around you do it, just that root won't work outside of ADB until it's done.
I assume that XDA folk are more familiar with ADB etc. than on the Oppo forums so the instructions skip over more detail here.

Updated the method to use fastboot boot instead of fastboot flash.
This should work around the issue with phones that can't flash twrp, and also leave the stock recovery in place which is more useful to have until we get some custom roms.

I was using modified boot.img to get root and then edit init.qcom.post_boot.sh. Now my wi-fi is broken. Can I fix it without wiping? Maybe flash some other boot img?

Fixed it by flashing boot.img from 150208, root still there due to script edit.

Updated the OP to use the modified stock recovery (Wmjan's recovery for the N5207) as this will be friendlier to noobs and also make it easier to install OTAs.

Anyone know where to get the root coloros file? Link doesn't seem to work for me...

You could also try this. It worked on my girlfriend's R5 running a similar version of ColorOS. Didn't need modified recovery or anything, install it, run, click the root button, and it'll reboot to recovery and root for you.

can this root work with Chines n5207

Hello,
I'm from Malaysia,
I got problem with my N3 / N5206 after update the newest version of software...now it cannot detect any line signal and open a wifi...what the problem,can u help me...

I can't make the WiFi to work again. Installed all versions of firmware and no luck....
Update: I was using the wrong tool to flash the firmware.
Don't update the phone with Msm8974DownloadTool !!!!
You have to download and install QPST_2.7.460 and place the phone in download mode by pressing volume + and power button and then in QPST load the firmware N5206EX_11_A.11_150528_SVN6225 or Oppo_N3_N5206_EX_11_A.13_151230 or N5206EX_11_A.10_150519_SVN6196
After flashing the wifi is working but you gonna loose the NV ram backup for the IMEI numbers..
Then you have to open dealpad with *#801# and anable Full-port ON
In QFIL(QPST) click on Tools then click QCN Backup Restore
Choose the qcn file and press restore.
Everything will work again after reboot the phone...

[Help] Asus Zenfone 2 ze551ml bricked and denies ADB pushed files

Hello, I'm needing some help with my 4gb 2.3 ghz rooted Asus after attempting to installing xposed framework. I'm certain it is bricked. Currently it is still able to charge and access the boot loader, but I am not able to flash the phone. The ADB shell just responds with "Access Denied". The phone was encrypted before I tried the xposed install so I'm guessing it messed up the process and is blocking my from using ADB. I did try factory resetting, but I guess that just covers the user app data. I also had debugging enabled within the developer options before everything went haywire. Any suggestions would be helpful, otherwise I'll just have to send it to Asus support for a pretty penny. It doesn't have warranty and I'm positive they don't really help you when your phone is rooted.

Try to wipe /cache. If it doesn't work, backup all your important data and wipe /data in recovery.

Ok, I did a data factory reset and wiped the cache. The problem i'm encountering now is i get status 7 in ADB when attempting to push a new zip of firmware to the phone. I know status 7 means the firmware cannot be installed due to system modification and root. So i'm thinking i'll have to reflash a pre-rooted system.img with droidboot.img and boot.img (recovery is functioning properly so i don't believe that i will need to flash recovery.img) I am also having a hard time finding detailed guides concerning flashing images and getting the zenfone 2 into fast boot. I did try a fastboot reboot fastboot command, but i,m thinking i'm missing a few important details on prerequisites to flash the phone.

What adb command you ran? It should be "adb sideload filename.zip"
If you can't, rename your firmware file to mofd_sdupdate.zip, copy to external sdcard, boot recovery then it will install install the zip automatically. Root using temp cwm/twrp.
If the above method doesn't work for you, flash a pre-rooted firmware.

Encryption issues on Nougat firmware

Hi guys,
just nowadays I installed OxygenOS Open Beta 10.
I was upgrading from Open Beta 7, but since I unlocked bootloader after doing that, we can say that I did a clean install (everyone should know that fastboot oem unlock erase all data).
However, I'm having troubles both with stock recovery and TWRP v3.0.2-1.28: pattern won't to be recognized.
If I disable pattern requiring at bootup, in recovery I need to type "a password" (that obviously is wrong in any case).
I tried to reinstall more times the firmware, also did factory reset both via stock/TWRP recovery and fastboot commands.
But nothing has changed.
System is working, but I can't access to recovery anyway.

You could try with other TWRP versions? Say 3.0.2-22

It's a known issue

Use twrp v3.0.2-1.19
Works with no issues, except a mouse pointer in the middle of the twrp. It does not interfere with anything, it is just there (a bug).

If you are on f2fs and encrypted, the blu spark kernel dev released a new recovery that supports f2fs decryption in TWRP. It may save you all the hassle. All you need to do is flash that updated recovery from fastboot and then try to decrypt. It should work fine.

All you have to do is wipe data partition. Reformat it as f2fs, all in TWRP and then reboot system and proceed with setup. Done!

Probably it would be risolutive, however I want to stay on latest Community Build.
I can say that sideload won't work with Open Beta 10: it can be flashed only via recovery (both TWRP and stock).

Are you referring to this recovery?
Yeah, I would be in love both with you and the developer, if it works properly
Tomorrow I should try, I'll keep you updated :good:
UPDATE: I've always loved Magisk, since v7 (when I've started using it).
Magisk is the workaround for encryption: just today I've flashed it together with Open Beta 10.
Now encryption is disabled, so goodbye to recovery troubles.
However the issue can't be considered solved because of a stupid workaround, this is not the right approach: I will try @abhibnl solution (re-enable encryption, then install latest blu_spark recovery).
Thanks all for answering.

UPDATE: I've always loved Magisk, since v7 (when I've started using it).
Magisk is the workaround for encryption: just today I've flashed it together with Open Beta 10.
Now encryption is disabled, so goodbye to recovery troubles.
However the issue can't be considered solved because of a stupid workaround, this is not the right approach: I will try @atulclassic solution (re-enable encryption, then install latest blu_spark recovery).
Thanks all for answering.

Yes i was referring to that recovery. 1 user has responded that it worked fine on his f2fs encrypted storage, so i believe it's worth trying. I am not on f2fs so i personally can't test it for you. But i would advise you to atleast give it a try. You never know when you by mistake boot right after a fresh stock rom install with stock kernel, and it will immediately encrypt your storage. So, you can't always just keep formatting internal memory. A proper TWRP recovery is indeed required for both ext4 and f2fs. All i am waiting for is updated kernel sources for recovery devs to work on.

For the many having issues, here's a step by step:
step by step install for OOS 4.0 and twrp-3.0.2-1.28-op3.img
Have OOS stock recovery installed on your phone. You must also have adb installed on your computer.
connect your phone to your computer via usb and open a dos command session on your computer.
On your phone, reboot into fastboot (bootloader).
From adb command on computer, type fastboot boot twrp-3.0.2-1.28-op3.img.
First make a backup and copy it to a safe location.
Now wipe everything - Internal, system, data, cache.
Reboot to Recovery. This is the stock OOS recovery!
Go to install from USB and then enter sideload mode.
On your computer dos prompt, type adb sideload (path)OnePlus3Oxygen_16_OTA_035_all_1612310359_e10cadfb2af7.zip
Allow the long and slow process to complete and reboot.
Upon reboot, it is encrypting the data partition as EMMC.
Upon bootup, enter setup and go through it quickly as you will have to enter it again so do not waste time configuring it.
Once setup is complete, reboot into fastboot.
From DOS command, enter adb and type command fastboot boot twrp-3.0.2-1.28-op3.img.
TWRP will boot up asking for encryption password. Hit cancel and then swipe to allow modifications.
Go into mount. Only the system and cache will appear. Back out and select WIPE.
select ADVANCED WIPE and data partition only.
Modify the data parition by selecting Repair or Change file system.
It will list the current mount point as emmc. Select Change File System.
Select F2FS and swipe.
This will wipe current data partition and reformat it.
Once you have done this, while in TWRP, select the ADVANCED button on the main menu.
Now select ADB SIDELOAD and swip to start sideload.
On your computer in ADB, type command adb sideload SR1-SuperSU-v2.79-SR1-20161221223537.zip.
Now reboot system and go through the usual setup and your done.

TWRP v11: the definitive solution

If you are on f2fs and encrypted, the blu spark kernel dev released a new recovery that supports f2fs decryption in TWRP. It may save you all the hassle. All you need to do is flash that updated recovery from fastboot and then try to decrypt. It should work fine.

FINAL UPDATE: the specified recovery is working with Open Beta 10 decryption.

If you have modified ramdisk or kernel flash the stock images of them as well.

You can download kilroystyx's TWRP, here.
You can find more information about going back to stock via firmware files and download KingOfMezi's TWRP, here.
After you boot up a custom system, you will not be able to boot kilroystyx's or KingOfMezi' TWRP.
If you need TWRP at that moment, use dil3mm4's Treble TWRP.
This TWRP cannot manage your data and files. You can use ADB, or use your external SD card to flash files.
Stock firmware files are here. All you need are system, recovery_ramdisk and ramdisk images.
Extract the UPDATE.APP from the ZIP file. You can extract the partition images by Huawei Update Extractor.
If you have any other questions, feel free to join our group. You can ask anything without hesitation.

If i follow your guideline, when i revert back to EMUI, TWRP cannot mount system.
It's weird cause i did flash a lot of treble roms and went back to stock several times before but not with your method.
Every time i go back to stock i got a different problem to troubleshoot due to encryption i think.
The best way i found:
Going back to EMUI
Wipe data and cache via stock recovery
Flash stock system image via fast boot
Let the system boot to the setup wizard
Flash Pretoriano80's TWRP via fastboot
Restore the backup
Wipe Dalvik and Cache

Find the complete firmware of your device and download the update.zip.
both are extracted from UPDATE.APP that is inside the update.zip
Unzip UPDATE.APP from the .zip file, then with the "Huawei Update Extractor" open the UPDATE.APP file and the files you need should appear and you're done, you can extract them

Is there a reason, why this guide only mentions
fastboot flash system systemimage.img

while the "official" one (https://www.xda-developers.com/flash-generic-system-image-project-treble-device/) mentions

Cause you need to full wipe after a different system flash ?
I suggest:
- flashing system.img
- flash stock recovery
- full wipe

How unlocking bootloader please reply bro

Hi, I have a couple of questions.
Firstly, why can't you flash images from TWRP? On the OpenKirin website it says they don't support it at all. Is it TWRP's fault or Huawei's? On my P9 lite I had a while back it worked perfectly.
Secondly, I would like to know what the difference is between the TWRP versions. Is there no support for backups on KingofMezi's one?
Thanks!
