Problem with flashing new ROM

Hi all,
A while ago I rooted my Z3C and flashed a custom ROM. Today I wanted to update to a new version and I messed up very bad. I always was a die-hard flasher so I did things as always. Downloaded the ROM as usual, wiping as usual (I always wipe everything). Tried to install the new ROM and got the message that it can't mount /system. Looked this up and it seems that Sony got a kernel protection for /system and /cache, which I didn't know.
But now the actual problem. For some reason my system partition did got wiped, as result I can only acces recovery. But I still can't flash ROMs due the kernel protection. I tried to sideload the RICDefeat to disable the protection but this didn't work. Also tried to go back to stock with the EMMA tool but this didn't work either as the application doesn't detect the phone.
Anyone has a good idea what I can do now? I didn't backup my system partition, but I guess it doesn't matter as I don't have R/W for system.

So I assume you didn't unlock your bootloader before you tried flashing a custom ROM? Which Recovery do you use?
If you hold volume up while the phone boots up (enter fastboot), does it detect your phone there?
Did you install the proper z3c driver and does your device show up in device manager (maybe as unknown?) ?
This guide might help even if you don't want to root but flash a fresh firmware: http://forum.xda-developers.com/z3-compact/general/how-to-root-backup-drm-keys-t3013343

Sorry, I should have mentioned this.
Bootloader is unlocked by the Sony website. For recovery i use XZDual, but for some reason I can only acces TWRP.
Fastboot is detectable and all drivers are installed correctly. Normally it wouldn't been a problem, but I also didn't have my system authorized for ADB as I just upgraded to W10.

You could try to flash cyanogenmod over fastboot now and see what happens (hope you backed up your TA partition first). I usually just prepare the flashtool (select image and press flash so it waits for device), then I hold down volume down and plug in the USB cable.
First I used to have some issues because of Windows driver signature enforcing but after disabling that it seemed to be fine.
Ohh and: Does TWRP print a log when you try to mount /system ? It might help to flash a kernel in fastboot then (could extract the cyanogenmod one from the zip [boot.img]), not too sure since I havent used a Sony Frimware for months now.

I am trying now as I typ this. The only log I get from TWRP is that it can't mount system.
@ edit: Didn't help. Still getting message that system isn't readable/writeable.

Did you try to go in TWRP and repair/change /system ? Also make sure you dont have the rm -rf option selected instead of properly formatting.

Soft bricked Nexus 6? - "Your device is corrupt. It can't be trusted and may not work

Soft bricked Nexus 6? - "Your device is corrupt. It can't be trusted and may not work
I unlocked the bootloader using the Nexus Toolkit (wugfresh) succesfully. However, while installing TWRP Recovery my device now appears soft bricked and I am unable to boot up nor get into Recovery mode.
This is the message I get:

It comes on briefly for a second or two, and then the phone shuts down. I attempted the suggestions listed here (
Dismiss the warning
The warning message should go away on its own after about 10 seconds and your device will continue starting up.
If you still see the warning message, you can choose to continue starting up your device by pressing the power button once.)
but they do not work. The phone will not continue to boot into System.
Help?
EDIT: I can get into Recovery Mode now. However, it wont go into TWRP (it did before), it now just has the Android on it's back with the red exclamation triangle reading "No command".

reflash twrp
flash a custom rom

Unlocking the bootloader shouldn't cause that message to show up. What were you expecting the toolkit to do? And do you know what it successfully did?

It happens whenever I try to root the device. I am able to get into the bootloader, and then reflashing to stock resolves the issue. But every time I try to root the device, it refuses to continue to boot into system after flashing the message. In summary, it successfully unlocked the bootloader but wont root/ flash TWRP.

Consult the guy who made the toolkit that ****ed up your phone. You clicked his button, rather then run a short list of well known commands we could help you with, so we have no idea what you did right or wrong... Maybe you didn't click hard enough.
Alternatively, read one of the many many many guides here, and use the single command needed, and if there are any errors copy and paste the console output (using code tags) here and we can sort you out in a minute or two.

What root are you using? That is probably the issue. If you use the older style root you need a modified boot image. I suggest the new systemless root.
So to fix this lets do this:
1 Use the toolkit to flash stock and unroot.
2 Flash TWRP
3 Copy the systemless root 2.65 to the !readytoflash folder. Delete the three files that are in there. The are from the old root way.
4 Reboot into TWRP and use it to flash the new root.
When you exit TWRP it will offer to root your phone. Say no. And stop after each step and make sure the phone is ok. So we can tell what went wrong if there are issues.

Thanks, I will give that a shot. FWIW, wugfresh Nexus Toolkit is an established tool and worked like a charm on my Nexus 5. But I also understand that things might be different for the 6 and the toolkit may not be the best option anymore. My fault for that assumption.
I will try TonikJDK's suggestion and report back.

Hi,
Had the same thing...
Really DONT know what the hack with with these wonderful people who developet these tools that do not mention ANYTHING regarding the issu in the main page of their tools here.
I think that you should follow the instructions:
1) Download shamu-mra58k => extract => take bootloader + radio + boot + cache + recovery + system + userdata => compy to platform-tools folder (under SDK).
2) Open CMD (open command prompt...) from platform-tools folder.
3) Type: fastboot devices (to know that pc recognized your N6) & than type the commands as shown at the attached screenshot.

That looks like a Wugfresh NRT log...
But why not go the whole way and use the latest 6.0.1 MMB29K?

Your not along in getting that message after using the Wugfresh Nexus Root Toolkit as I got the same message on my brand new Nexus 6. The toolkit installed TWRP fine, but somewhere in the three files it asked me to install in TWRP (beta superSU, busybox, and another file), there was a problem. I ended up clicking flash stock + unroot and I did this twice and it worked the second time. Then I locked the bootloader and did a factory reset. So far so good. I will root the device again, but by another method.
However do note that I have used that Toolkit for a Galaxy Nexus, Nexus 7 & very recently with a Nexus Player and its worked great every other time. I think it has something to do with Marshmallow, but I'm not sure.

Best and easiest method to root Marshmellow imo is to flash TWRP and CF`s latest systemless root zip 2.65.

That's not the NRT log (just flahsed manually by fastboot without any script).
I think with up to 6.0.1 MMB29K(not included) there is no issues.

Just kidding...
I've been running MMB29K for a couple of weeks with no problems. I was just suggesting that if the OP was going to go to the effort of flashing then he/she may as wll use the most recent version. Or even hold off for a few days for the possible new one in January. Hey, that's today...

... it bricks your phone. Unless you know exactly what you're doing. But then you don't really need it anymore.
People, Marshmallow is already past the toolkits. It has an update once a month, and the toolkits don't have time to be updated fast enough. You'll be bricking your phones constantly if you don't learn your stuff.

This error is the consequence of a " feature " of marshmallow that checks if your system is modified and issues this error message.
Here is how you "unbrick" your phone after running into a problem like this:
1- Download and flash a stock rom. Make sure all partitions are flashed (i.e. bootloader, radio, kernel (aka boot), recovery, cache, userdata, and system). If you don't know how to do it Google it.
2- Boot into the stock recovery and wipe data, cache, and factory reset.
Now that your system is restored, here is how you root it:
1- copy superSU 2.65 on your internal SD card.
2- reboot into bootloader
3- flash twrp
4- very important: do not boot from the bootloader back into Android, rather boot into recovery.
5- when you are booted into twrp recovery, flash superSU zip. It will both root your phone and patch the kernel so that it doesn't give you that curroptrd phone error.
One last thing, not to rub it in for the gentlemen who posted the question but for other who are considering the easy way of using a toolkit, and please don't get offended by this. No one is against convenience but if you are unable or unwilling to learn few simple commands to unlock and unroot your phone you probably are not the type of user who needs to root the phone and chances are that after using a toolkit something will go wrong and you will have to learn the steps the hard way after the effect. Toolkits are good intentioned tools that should be avoided at all cost.

No offense taken I've rooted quite a few phones although I'm far from being an "expert". The toolkit was really just for convenience, and I went back to using it because it worked like a charm for the Nexus 5. It really was the go-to handy tool. To be sure: As I've stated above, I was able to recover the phone on my own. Still not rooted though, but I'm getting there. Sure, M is good enough on it's own, but frankly I can't wait to get back on a Cataclysm ROM.

I used the Chain Fire method and ended up in the same place. I can still access TWRP and fastboot, I am in the process of downloading the stock image.

You have to flash back to stock first. Marshmallow is checking for system mods, so if you don't undo the previous changes it will trigger again. Flash stock, twrp then 2.65 chainfire.

... You don't need to root to install a rom.
In fact, while installing the rom you will likely wipe your /system partition and any other partition you mess with to root....
What is it you think rooting actually does? Why are you doing it? What part do you think it will actually play in you installing a rom? Don't just do random ****. Learn what things do, so you can do what you want. This is why people hate toolkits. They promote this kinda of mentality where you just do stuff you don't understand in the slightest.

[Recovery] [YB1-X90L] TWRP

managed to get twrp working on YB1-X90L (Yoga Book - Android - LTE)
it's my very first try to create sth. like that, so I have absolutely no idea if everything works as it should. (took the twrp from yoga tab 3 pro root thread and changed it to fit my device mainly using this guide and some minor changes on my own)
if you want to try, you do it on your own risk. if sth. breaks, please don't blame me!
I strongly suggest not to flash it, but just boot it via fastboot:
1. download recovery
2. make sure adb is working
3. put the recovery into your adb folder
4. unlock bootloader (attention: unlocking the bootloader does a factory reset. so back up your data before) see here how to unlock bootloader
5. boot into bootloader (either: 'press power + volume up' or use adb typing 'adb reboot bootloader' in terminal
6. open terminal and naviagte to your adb folder (with recovery.img in it) then type: 'fastboot boot recovery_twrp.img' (adapt file name in case you changed it)
7. tablet should reboot and boot twrp
this method does not flash twrp permanently. your stock recovery remains untouched!
!!!BEFORE YOU USE TWRP TO CHANGE ANYTHING, PLEASE MAKE A FULL BACKUP!!!

as i said, it is a beginner's job. so here is what i noticed so far:

---reserved---

before you ask...
yes, of course, i have already tried to flash supersu, but unfortunately I had no luck so far. The script always aborts because it fails patching sepolicy of boot.img.
so if anyone knows a solution for this, feel free to help!
edit:
found another way to root, look here

Amazing! I never thought yb would have twrp. I've been looking for a way to install gapps since I bought yb. After my final I will definitely have a try.

did backup 2 times and restored all partitions a several times which worked well.
only tried to install supersu, which in general went well although su couldn't patch boot.img (but has nothing to do with twrp I think)

to lock the bootloader you must have stock recovery...hopefully you din't flash twrp.
I do not really know, whether locking the bootloader will work flawlessly due to the changes made by root
when you lock the bootloader it will once more wipe all data - so back it up before, normally root should stay (although I don't know for sure)
to lock the bootloader just use the following command in terminal:
Code:
fastboot flashing lock
if you are not sure, try to search xda for more information about relocking.

Do not get me wrong but you say make a full back up with twrp before doing anything but based on your description twrp cant be installed without unlocking the bootloader which in return erases the device.
Is this catch22 or am I missing something here?

to your first question:
1. well, here we are not talking about backing up your user data but your rom (stock rom so to speak). if anything goes wrong you can always go back to stock.
2. if you want to peform ota update you can't do it with modified system (ota will fail), so normally you must go back to stock, update, root again
to your second question:
it's just a warning that your bootloader is unlocked, nothing more. it shows with every boot and after 5secs just boots normally.
you can easily find out about the advantages and disadvantages of an unlocked bootloader e.g. here on xda.

I can't thank you enough for this. I live in China and was only able to buy the Chinese version of the Yoga Book, which doesn't come with Google Services installed. However, using this TWRP recovery I was able to flash Google Services (and get root) which makes my Yoga Book so much more useful! Thanks so much!

Have got as far as flashing TWRP, but find that any attempt to backup - to internal storage or sdcard - is cancelled. Have checked on googz but cannot find any specific info. Any help would be appreciated

which yoga book version?
did you flash it or booted it?
how about a log (--> advanced --> copy to sdcard)?
is 'mount read-only' in 'mount' deactivated?

Left it overnight and tried again today. It's OK this time. I fiddled with settings, mainly to deselect the read-only system option. Each stage of this process has been pretty frustrating (I'm used to hacking sammy devices - this is first and last time with a lenny). Stuck now trying to get root - it will probably take until tomorrow! btw, ver is YB1 X90F (Europe/UK).
But thanks for taking the trouble to reply. And thanks for giving us the opportunity to hack the YB.

Worked on the wifi version too.
You may not be a developer but you are a pretty smart guy to be able to figure this out on your own, my hat is off to you. I rooted my wifi version of Yoga Book using your instruction and the only notable issue I ran into in the process was that i had to install new Android usb drivers in Windows to get the reboot-bootloader command to work, other than that little hiccup it worked like a charm. One other issue I ran into that was of my own making was that Titanium backup encouraged me to upgrade super user which led to a soft brick, thankfully I'd backed my book up and was able to restore it.
Thanks for taking the time to share this with us because rooting made this device a much better experience.

hi all, Im reslly happy to see the yb can really root. but all i want is to have the google app work on my yb china version.
am not a techy, hence most of the insturction mention here is very strange to me.
if anyone can help to write down the step by step on how to flash twrp and install google app to yb will be great thanks..

If you just want to install gapps, there is no need to root.
1. download gapps from opengapps.org. select x86_64 6.0 version. select nano or micro version if only want google play to be worked.
2. put the gapps zip file into your root of your YB.
3. just follow the instructions of this post to boot into TWRP
4. In TWRP, select install zip file from SD, then select the gapps to install
5. after finish, reboot to the system.

@danjac Hi, did you keep the boot to bios option in the reboot menu?

[GUIDE] How to ROOT the HTC Desire 10 Pro

Hello Everybody !!
I'm not a developer but I successfully rooted my HTC Desire 10 Pro and since many people seem to have problems,I decided to make a guide. The computer OS I used was Windows 10 but if you use linux, I'm sure you can adapt to the method.
1. First install device drivers and download ADB fastboot from this thread
2. Dowload TWRP 3.1 for your phone variant from here and move it to the ADB fastboot folder and rename the img file to "twrp"
twrp-3.1.1-a56dj_pro_uhl.img Desire 10 Pro Single SIM
twrp-3.1.0-a56dj_pro_dugl.img Desire 10 Pro Dual SIM
3. Press shift + right click and select open command window here.
4. Go to developer options on your phone and select Allow USB debugging and Allow bootloader to be unlocked.
(Very important step)
5. Connect the phone to your PC and check the connection by typing the following in the command prompt.
adb devices
If it shows only one device, you're good to go!!
Otherwise remove any other connected phones/devices and disable any Android emulators if you have them. (Like Bluestacks)
6. Go to HTCDev website and unlock your bootloader, (HTCDev will give those instructions), the phone model isn't shown but select "other supported models".
(Warning - This will erase all your data so make a backup)
7. Type the following into the command window to boot your device into bootloader/fastboot mode:
adb reboot bootloader
8. Once your device boots into bootloader mode, type this into the command line.
fastboot flash recovery twrp
9. Once TWRP is successfully flashed on your device, type this final command to reboot your device.
fastboot reboot
10. Download SuperSu latest version
SuperSu v2.82
11. Copy the SuperSu zip file to your phone internal storage
12. Then type this command to go to TWRP,
fastboot reboot recovery
13. Wait for TWRP to load and tap Install
14. Select the SuperSu zip file and flash it
15. After flashing finishes, tap on Reboot System
16. Congradzz !!! Your HTC Desire 10 Pro is rooted now.
Now you can further customize if you like by installing Xposed.
Thanks for following and please reply in the comments if I have made any mistake or if you need more help.
And I'm NOT responsible for any damages even though it's unlikely to happen.
Edit : This was confirmed to be working on version 1.18.400.20 and it doesnt seem to work on 2.13.709.20. Please have a RUU if you're trying on a version in between, just to be on the safe side.

And all of XDA for being awesome ?

Any chance on doing a full backup before installing TWRP, as I don't have a default recovery of 1.18.400.20 dugl dual sim and still hope for OTA?
I hoped for "fastboot boot recovery" but I think only with nougat firmware was reimplemented.
Thanks

I think HTC disabled remote recovery booting so you'll have to replace the stock recovery.img
But I think I saw the stock recovery.img for our phone in another thread. You can download it and flash in case of a new update.
And what do u mean nougat firmware was reimplemented? Did you get the Nougat update ?

process failed
Hi everyone,
tried this process on a A56DJ_PRO_DUGL with system OS-2.13.709.20 and the last step (supersu 2.82) failed, it said unable to modify boot image and aborted.
Used magisk 15 and it was able to modify boot but it did not boot, always asked for password for encrypted data, even after factory reset. I tried to restore the backup I previously made with twrp 3.1.1.0 (boot + system) but now it does not boot. Download, bootloader and twrp works anyway.
I will try to fix it, hope it serves as guidance to anyone trying to root the same 10 Pro version.

Try flashing the uninstall zip for magisk.
Also, if u have a backup, try to wipe boot and system partitions before restoring.
Good luck

I did try to uninstall magisk but it gets stuck in the boot process (only htc logo), the same thing happens with the backup I made with twrp (only htc logo), the best result so far is applying magisk to the boot, then the system starts but keeps asking me to decrypt the storage, the exact message is "The password you have entered is correct, but unfortunately your data is corrupt" I did factory reset but does not solve the problem, it keeps asking for the password.
Also RUU for my OS-2.13.709.20 is not available so I'm currently stuck.
These things get harder and harder every day

Desire 10 Pro recovered
Finally the last option was to fully stock flash with RUU 2.13.709.20, but now I am back to step one.
At least it works
---------- Post added at 04:20 PM ---------- Previous post was at 04:08 PM ----------
Been human means to keep trying, so I tried again, now I did full factory wipe before applying supersu 2.82 (not working) or magisk 15 (works but keeps asking for a password to decrypt storage).
So I can confirm this procedure does not work with OS-2.1.3.709.20.
If any of you is able to root this version I will be glad to try again in the future but by now I'm done with htc 10 pro.
Happy new year everyone!

thanks for the guide, I was waiting for it and just came in time
I am wondering if this method will work on a56dj_pro_dugl software number 1.18.401.20 ?
what software number did you tried it on ?
thanks for the help

thanks for the guide again,
after pulling my courage together I decided to do it on my a56dj_pro_dugl software number 1.18.401.20
everything worked fine from the top to step 14 but there is one problem, flashing the SuperSU zip file is failed,

never mind
just rooted it using Magisk , apparently SuperSU is not applicable on my device
I used the same method as SuperSU zip
downloaded the latest version of Magisk (v 15.3) zip file and install it using TWRP
and everything is fine ever since
thanks folks for being awsome developers :laugh:

I just need an .apk from a system app called "sangam IME" it's a keyboard & u can extract the .apk with lucky patcher or any other similar apps
I need it like hell , caused I removed it & then realised it's the only keyboard that pops up in encryption page at startup & not having it means I can only reset my phone when I have a physical keyboard connected with otg ! Thanks alot

Hi!
Sorry for the delay, I havent checked my inbox for quite some time.
I searched around for this Sangam IME everywhere in,
/system/app
/system/priv-app
/data/app
/data/app-private
But I couldnt find it. I even tried using 3rd party apps like you suggested but it simply doesnt seem to exist.
Even a quick Google search didnt give me any leads.
So are you sure the name is correct ?
Or maybe any more ideas on where to look for the apk ?
Sorry I couldnt be of more help

[RESOLVED] Bricked after flashing firmware for Pie, stuck in md5 checksum bootloop

Hello,
I post here after 12 hours of continuous search and attempts at fixing things on my own, which may have dug me deeper into trouble than if I've asked for a tailored solution to this issue. Apologies for repetitiveness if I've failed to find answers elsewhere.
I was running LOS 15.1 with custom kernel and maybe the 5.0.8 firmware or lower. I don't recall the version.
In an attempt to flash LOS 16.0, I performed a nandroid backup, but didn't back up my internal storage. That was stupid of me
I grabbed all the files needed, and started by flashing the firmware version stated in the flashing guide for LOS 16., which was 9 point something.
Phone bricked, blank screen.
Got hold of a factory reset tool from an unbrick guide here, followed their steps to completion despite repeated failures in the MSMDownloader.
Now my phone boots in fastboot mode only, adb on PC neither can detect nor interact with the phone, and it is stuck in a md5 checksum bootloop with "modem" and "dsp" in the red, and all attempts to boot into recovery lead back to the md5 checksum screen.
On fastboot mode, "Bootloader version" and "baseband version" are both blank.
This is all I know to provide at the moment. If there is any way to salvage the phone with the internal storage intact, I would prefer that please. But I won't look a gift horse in the mouth at this point if I ultimately have to wipe everything clean to fix the phone.

bump pls
even bad news is appreciated

Even fastboot cant saw your device thru "fastboot devices"? Do your ADB drivers up-to-date?

Thank you for answering.
Fastboot can see and use the device. Flashing is possible through it.
ADB cannot. I'm not sure if it's the latest version on my PC, but I recently had the phone connected to a different PC with a recent ADB installation and the results were the same. ADB doesn't see the phone.

Hmm.. does phone in TWRP works like USB storage?

Phone fails to boot into recovery.
I flashed TWRP but it always boots into the failed md5 checksum anyway.
Recovery doesn't work.

Worth noting is that TWRP flashing causes the recovery: ok message to also read as recovery:failed.
Flashing the stock recovery that came with the unbrick tool using fastboot makes it recovery: ok

It won't boot into any recovery, stock or otherwise. Only brings up the screen pictured above.
EDIT: By "stock recovery" I mean whatever the unbrick tool had flashed into the phone using the MSMDownloader utility.
The version of OOS included in the tool is mentioned as 3.2 or some dated system. Maybe a more recent recovery might work?
I can't find a standalone, recent stock recovery image. I'd flash one if I found it.

Fastboot and adb will never work at the same time, by definition. If Fastboot works, you are in fastboot mode. adb only works in OS or alternately in TWRP, and will never work in fastboot mode.

I can't personally think of anything. I just wanted to point out the fruitlessness of trying to use adb, so you don't waste time trying to get it to work (since it never will).

I forgot a detail in the middle of the story.
Right after I flashed the pie firmware, it restarted and I was given a prompt that said something along the lines of "Flash successful and everything, but decryption failed. You will lose all data if you boot, are you sure?"
I turned off the phone, from there it bricked with a blank screen. It was then that I got the unbrick tool and went through the rest of the earlier story.

I appreciate you reaching out and offering closure. It seems this phone is fried.
Thank you.

I got past the MD5 checksum hurdle, and I flashed TWRP. It works.
I can't access internal storage to flash anything from the phone, not even the TWRP nandroid backup, but ADB is an option again.
Decryption refuses to take my password even though it's correct.
I do have a backup of the nandroid on my PC. Could I flash that via ADB?

It would help others who get into the same situation if you post how you got passed the MD5 checksum hurdle.
If you can get into TWRP I would suggest you use the latest version 3.3.1-0 and use wipe>format data (not wipe>advanced wipe) which will clear the encryption. It will give you an ext4 data partition, which is fine. If you want to change it back to f2fs use wipe>advanced wipe to reformat it to f2fs.
I don't recommend using an unencrypted phone so my next step is to copy from your PC to the phone the ROM zip file and anything else you need to flash. I would flash the full OOS zip and let it boot up as this will automatically encrypt your data. It will also replace TWRP with the stock recovery but you can flash TWRP again using fastboot. You can then go back to TWRP and set things up the way you want, including restoring the backup you have.

Thank you for dropping by.
Regarding the couple of errors in the MD5 checksum, "modem" and "dsp", the problem lied in that I didn't know which files I'm supposed to flash using fastboot to fill their spots.
By referring to the forum post of the firmware here, I found one workaround was to "consult META-INF/com/google/android/updater-script in the flashable zip of the firmware ... to check which file from the firmware-update directory goes to which partition."
From there, I inferred that "modem" takes the file named NON-HLOS.bin, and that "dsp" takes adspso.bin
Flashed them via fastboot, and I was greeted by a successful boot to stock OOS 3.1.2, the version provided by the unbrick tool I used.
However, it seems that the damage done to the phone (either by the failed firmware flash or the unbrick tool) has led to the internal storage being corrupted, or perhaps the damage was done to how the system decrypts internal storage. I am a medical student, so most of these intricacies are way out of my league.
I was hoping to recover the internal storage, but would gladly part with the data if it means I can use the phone again. There was nothing particularly important on the phone that the TWRP backup didn't have.

Pardon me, but which file system would be most suitable for each partition?
The Wipe>Advanced Wipe menu offers several file systems for several partitions. I'm inclined to leave everything as it is, but should I perhaps format the /system partition as f2fs for instance?
