Unmodified System Partition Bug [TWRP] - HTC Desire 825 Questions & Answers

when i charge my phone and it is powered off it boots into a recovery screen that says unmodified system partition and tells me to swipe to unlock but the touchscreen does not work if you swipe the only working button is the power button which just shows a pig padlock and then you have to swipe to unlock the padlock which doesn't work either. if i want to exit the screen i have to hold the power and volume button EDIT: i re flashed twrp using adb on my computer and the screen was responsive thanks for your help!

You just have to let it charge at the padlock screen. Then unplug the charger and turn on the phone, when the red text on the bottom disappears plug the charger back in. It's just a bug. It happens for me too.

was about to install a new viper rom from TWRP and when completed it was not booting. so i restored my back up and now i'm getting a fail "failed to mount data(no such process". installed a the original viper rom and now its showing decryption unsuccessful after the phone boots and showing Unmodified System Partition

Which TWRP did you reflashed and it worked?
I have the same problem, TWRP booting when i connect a charger on powered off phone, and the screen doesn't respond,
tried 3 different TWRPs, reflashed, but without success.
Does somebody have a stock recovery IMG for the 825 ?

Ok, i've managed to find it This is the stock recovery IMG, working fine, extracted from original firmware.

Credits go to nkk71 https://forum.xda-developers.com/member.php?u=2605798 for the great tool to exctract the firmware image,
without it i wouldn't accomplish the task.

[Q] ONE Max stuck on "HTC ONE" screen...

I was doing a backup with TWRP and everything seemed to go just fine. Then after a reboot i unlocked the phone to notice that it was leaving the lock-screen icons on the bottom of the page. I still had access to my notification bar and could clear notifications. Figuring that there had just been a mistake in the boot process, I held the power button to restart the phone. Well it never brought up my power menu to restart. Also instead of making me wait ten seconds until it flashed its lights and restarted, it just restarted in like 3 seconds. Now my phone is stuck on the HTC ONE screen and will not respond to anything including hold the power button.
My phone is rooted an s-off. I know that I have not posted at all on here, but I have been rooting and know how at least the basics on adb shell. I just have never had a phone lock up to this point. If I can at least get to recovery, I should have 2 or 3 backups to run. I just don't want to have to wait for the phone battery to die just to hope I can get to recovery.

Are you saying volume up + power button does not restart your phone nor does any help? Check if your phone is detected in computer and if so you can issue and adb reboot command
also since there is no removable battery HTC added a reboot function press home vol down and power that should do the trick
The phone is not detected by a computer, nor will it charge. Vol down and power is not cutting it off. Right now I am waiting for the battery to die so I can hopefully boot into recovery and do a restore.
Vol up + Power was the key. I was thinking it was volume down. Thanks for all your help

OMG THANK YOU SO MUCH!!!
:victory::victory::victory:
Just wanted to point out I ran into this issue also (Stuck on white HTC boot screen) after wiping my ROM and Vol UP + Power did the trick for me also (and then Vol Down + Power to get back to the bootloader).
i need help, guys
so attempting to install a new rom, i must have dont something wrong because now restarting the phone will leave me on the htc logo loop and restart. i still have access to hboot and fastboot. but when attempting to load into twrp, it shows the team win logo for half a second and then restarts the phone. then i installed cwm and it does boot into it but whatever option i pick, install zip, wipe data, ANYTHING, restarts the phone.
i have no idea what to do. i tried installing a rom using adb sideload but it stops at around 80%, ive tried installing different versions of twrp and cwm and same thing. i think it is bricked. im using the verizon htc one max. the only option i see left is the ruu toolkit but ive only been able to find the sprint version and then it says that bootloader needs to be locked and i have not idea how to do that from hboot, fastboot, or cwm
attempting to install superuser also fails
if there's anyone here that can help, please, any suggestions will be appreciated. thanks =:laugh:
Sounds like you're flashing the wrong TWRP.

May I suggest following these instructions?
http://forum.xda-developers.com/showpost.php?p=51753483&postcount=129
If you're able to complete those instructions outlined in that post, this should set you up with the latest HBOOT, Radio and TWRP (Recovery) for the Verizon HTC One.
Make sure you read the post fully before you start, especially this part:
fastboot flash zip firmware.zip (Be sure it finishes saying 'successful', not 'please flush again immediately'. If it says the flush again, rerun the command)
If you succeed in getting that done, see if TWRP still causes the phone to reboot and get back to us.

[Q] Acer A200 IconiaTab Stuck at boot screen...

Ok Here is what I have and have done: :crying: :crying:
All I did was turn it off then screwing around I held the power button and vol+ and hit screen rotate lock switch as it was booting, then it read:
erasing userdata
unrecoverable bootloader error
And thats it. unfortunately adb is not turned on and now the tab will not boot past the secondary booting screen that reads Iconiatab, what is worse since I still have the stock recovery I cant flash anything that I have found. I have tried to flash the Stock A200 rom that is supposed to be stock recovery flashable but it only gets about 1/4th of the progress line before the dead android with the triangle !! sign appears. and of course I dont have the cpuid or sbk, so I cant flash anything in APX mode either.... I am really pulling my hair out here.. and really need some help here it is my nephews tab and he is going to be really upset if I cant fix it.
Any way this is the name of the rom that wont finish installing in the stock recovery flash :
(Stock Rom)Acer_A200_AV032.RV09RC08_AV041.RV04RC02_PA_CUS1_1330081316944_80bf3f7e_decrypted.zip
( I am not allowed to post links yet... But any way the download is at 4shared, and I got the link from the Acer Tablet Forums)
It is Titled Original Stock Rom, and it should have been able to have been flashed through the stock recovery, but di not, and I dont know if it is the rom, or the tablet that is the cause of it not flashing through the stock recovery....
And I have tried a few other update.zips to no avail, but that was the only full rom I found, and certainly the only one with the bootloader blob in it.
Does anyone have any kind of advice for me, or do you know where I could get a rom that will flash through stock recovery?
I dont understand why this happened, the tab was working just fine then I had to reboot it while screwing with the buttons...
So if anyone can help me I would be most grateful, and I can follow most any guide or instruction as long as it can be located.
Thank You
PS - The Tab is 100% stock, no root, no custom recovery, nothing....

The problem was solved by following a YouTube video covering this issue, the video was in spanish, but was rather easy to understand even with the language barrier.
Simply keep doing same boot method over, and over until it works! 12 tries for me then a succesfull boot!
Press the power button and vol+ until the tab vibrates, then flip the screen rotation lock switch.
The screen will read erasing userdata, then the red unrecoverable bootloader error (0x190000008), hold down the power until the tab shuts down.
Continually repeat the proccess, and eventually it will read erasing userdata, and follow with formating cache, then complete. The device will reboot, and it is back tonormal now the stock recovery will finish flashing the ota update.zip so long as you have the right stock rom.
Now you can continue on with your tab however you decide, root, install a custom recovery, and rom, and of course unlocking the bootloader in fastboot mode with oem-unlock
Thank you.
the person who posted before this was correct on pressing the vol up key and power then when vibrates release power but holding vol up switch the screen rotation switch from the right to the left and stay holding the vol up key until it show the android screen leave it be and it will be done once finished loading. You don't have to keep repeating the process one time will work if done correctly. the vol up button is the button to the right when holding in landscape view and the rotation switch should also be in the right most position to start. anyway other than those details it works and it will work the first time. Good luck!

CWM Recovery hanged while erasing... bootloop problem.

Hello, today I wanted to restore my previous CWM backup. So i started with cleaning partitions before restoring. I've begun with system and my phone hang. I waited about 30 minutes, then pulled out battery with hope I'll try again via CWM. The thing is - I can't boot it into recovery: Volume Up/Volume Down+Power leads to normal start up (LG screen and nothing further). So i connected it to PC and wanted to make it right via ADB. Unfortunely it seems I had USB Debugging turned off, and ADB isn't recognizing my phone now... What should I do now?
I have rooted D620r with unlocked bootloader.

You must never delete partitions before restoring a backup especially system!!
CWM will do that for you...
Boot your device in factory reset mode (which simply boots CWM) by doing the following key combination: (while your device is off - pull and plug the battery to be sure) press and hold Vol - and power, when you see the LG logo, release the power button and press it again. Hold them until you see the facory reset mode, then simply enter YES. It will reboot to CWM.

Weird, I was always doing this when I had HTC Desire S
Used this countless times and always worked!
Ok, i've done as You said, something like CWM loading screen appeared, and then went back to LG Screen. LG Screen standing still and nothing happens
The only good thing is that I can access ADB for 20 seconds when CWM is "loading", but no action can be executed - every command ends up with "waiting for device".
Thanks for Your reply, though! :highfive:
EDIT:
I solved my problem by using "Emergency software restore" mode featured in "LG User Support Tool". I got clean, unrooted system now and I need to modify it again but...

Lock bootloader
Hello everyone.
I was just going to try out CM11, but got one question. Is it possible to lock the bootloader and revert everything to stock? There were some talks about new stock ROMs coming out and they might not work after a custom ROM.

SGP771 brick after unlocked and flashed 'boot.img' extracted from AndroPlusKernel v4

HELP: i had been going to flash MR by myself, but when i tried to unlock it and flashed the rooted 'boot.img' extracted from 'Z4T_SGP771_AndroPlusKernel_v4.zip', i don't get the 'supersu' on the desktop properly, after tried a few times, i did a factory reset, it now hangs on boot logo, there is no response to 'power' button long pressed down, looks it will power down until battery goes up, does anyone also experience this? how can i restore this?
The link i'm following:
cwm-twrp-android.net/download/sony-xperia-z4-tablet-lte/
it prevents me paste the outside link since this my first post, so i removed http prefix.
I solved it by myself, after pressing 'Volume Down' + 'Power', it reboots, and looks the factory reset did nothing, it's weird.
On the .260 firmware AndroPlusKernel v4 won't work. I had the same thing when I accidentally flashed v5. You'll need v10. Also, download this stuff from official sources, look in the AndroPlusKernel thread here on XDA.
So, get into fastboot in some way (I don't know how I got back into it, just hammered the volume rocker) and flash the correct v10 boot.img.

To go in flash mode press and hold down volume down and connect to your pc, the led become yellow for a few seconds so you must be fast to enter the command in ADB

Thanks a lot for your comments, i have root it successfully, is there anyone made it to flash MarshMallow? i tried to update it with TWRY with officially binary SW_binaries_for_Xperia_AOSP_M_v01_2.zip, but it tells 'Could not find 'META-INF/com/google/android/update-binary' in the zip file', does anyone know how to survive this?
I also find a AOSP version 'AOSP_L_MR1_160113_karin.zip' from www.androidfilehost.com, but it only contains image file, i tried to flash them all, others(boot, userdata, recovery) are all ok, but it hangs at flashing 'system.img', i terminate it forcely after waiting for 20+ mins, the system boot up back to 5.0.2 after that.
If i use TWRP to install this zip, it tells the same error with the official binary, anyone know if this will work?

Bootloop to recovery issue.

Hi guys.
I seriously need help right now.
My friend bought an s2 i9100 in cheep which was stuck on bootloop and he thought it could be repaired.
so we don't know what caused the problem.
But i was surprised that few repair shops weren't able to fix it.
let me explain the problem:-
when we hold power button or plug in a charger it show the logo, goes into recovery and reboots repeating it in loop.
so whenever i charge it goes into this loop.
we can use volume up & down key in those 2-3 seconds in recovery but not the power key.
we can access download mode and it doesn't reboots automatically but going into recovery mode manually also start this loop.
it's like we are only going in recovery mode again & again.
i installed this file "I9100XWLPW_I9100ODDLPC_I9100DDLPB_HOME.tar.md5" through odin and also used the pit file "I9100_STOCK-System_2GB-Data_512MB-Preload.pit" but nothing changed.
i don't know what to do now.
i cant find any gingerbread rom to test.
i don't know how it can be fixed,
so please help me.
Update
After doing a lot of things I finally managed to boot into system but the problem is not solved.
I flashed i9100XXLSJ which had modem and CSC files other than the PDA only.
The device actually booted in system (just the samsung logo) but it was a bootloop.
This time I kept holding power button by which the bootloop stopped and it successfuly booted but power button is not working inside the system so I can't reboot, power off or even switch on the screen.
By holding down up vol + home + power for a considerable long time I can boot into recovery. But again the power button is not working so I can't select any option.
I flashed a cwm touch recovery which is working.
So can anyone tell me what is the problem here and what can I do to actually fix it.
If you have problems with flashing stock ROM, consider flashing a custom ROM, like Cyanogenmod.

The problem is not about flashing it's about the bootloop & tell me can I flash cyanogenmod with Odin?
@kuro2052
Try flashing the 4.1.2 JellyBean leak ROM via ODIN linked in this thread (scroll down to you see "Another option for i9100"):
[GUIDE][Troubleshoot a failed Odin flash]
This will factory reset the device which may hopefully resolve your problems.

Actually the ROM you are talking about is the ROM which I flashed which is mentioned in my second post " update".
PDA = CODE_I9100XXLSJ.tar
PHONE = MODEM_I9100XXLS6.tar
CSC = CSC_HOME_OXX_I9100OXXLS1.tar.
That's how I got this far, previously it was impossible to boot into system.

In CWM touch recovery, you can swipe (or touch) to confirm the option.
Try factory reset. Reboot.
If that doesn't help, try wiping system, cache and data.
Let me know how that goes

Wiping data/factory reset and cache doesn't solve the problem.
There is format option in 'mounts and storage' so I formated system, data, cache & also emmc. But the bootloop is not gone. The only thing that is gone is the ROM because of those formats. I have yet to to install the ROM again.
maybe is a faulty power button... Do u have to push it down a little harder than normal?

It might be the problem of power button. Sometimes it boots as soon as I put the battery. It always boot when I plug in charger. Sometimes it boots after I press and hold the power key for maybe 15 second & sometimes it doesn't boot when holding power key & I have leave hold again to boot it. And important thing is when it boots, I have to hold the power key until the key lights up to stop it from bootloop but then the power is Jo longer functional in system. Same goes for recovery. But this is the only till nowROM which actually boots into system. Other ROMs were booting into recovery automatically.
I wanted to test cyanogenmod but I am not able to install twrp. I followed the steps here using HeimdallSuite https://twrp.me/devices/samsunggalaxys2i9100.html
I had no problem in the steps but the recovery is not actually replaced when I boot into it.
The recovery that I have currently is not able to flash isorec_twrp or any cyanogenmod directly. It always shows error code 7.
I am going to replace the power button with my friend's s2 (other friend who have an s2 laying around) only to see it works.
Anyways tell me how to install twrp successfuly.
The actual power button needs to soldered, I thought It would be a connector, so I am not going to do that. But as far as I can tell, the plastic button isn't the problem.
