[Xperia Z5 Compact Q&A, Help & Troubleshooting] Steveh8204:
So did they just replace the camera module that is plugged in to the top at the back? (obviously apart from battery too).

Your post seems to suggest overheat which caused motherboard damage too.

Unless I've read it wrong you're suggesting swapping the camera will fix the problem.

I know I'd obviously need a new back cover too.
[Samsung Galaxy Note 8 Questions and Answers] briwil:
I have the leaked ver of Oreo installed, but I have an app that's incompatible with the new OS, so I've been trying to downgrade for several weeks now, with no success.

I've seen answers online that completely contradict each other- use Smart Switch backup (tried that, didn't roll back the OS), tried several versions of Odin and firmware, always get 'FAILED AUTH'.

Also seen some posts that say you can't downgrade, others that say yes you can.

Is it possible? How can I find out which bootloader I have?
[Samsung Galaxy Note 8 Questions and Answers] AmmaRoOoX:
I heard with Oreo they did the same as Apple do. They stop downgrading the OS, but I'm not sure about it.

I hope other members can help you.

Fixed

And just like that, as soon as I post this, I get it to work. After spending all night trying different versions of Prince Odin and different firmwares, I just switched to normal Odin and it worked immediately, so back to 7.1.1
[Samsung Galaxy Note 8 Questions and Answers] PAULG1919:
can you please tell how and what you used to down grade note 8 back to 7.1.1....thanks
[Samsung Galaxy Note 8 Questions and Answers] sefrcoko:
Have you tried Odin and the firmware for your device?
[Samsung Galaxy Note 8 Questions and Answers] j_hansen:
as long as the version you want to downgrade to is same version bootloader would it not be fine?

ie.. v3 to v3 is fine but not v3 to v2

I haven't been rooting or flashing with the Note 8 yet but that's the understanding I have from other threads

I think they changed something in oreo , where you cant downgrade now. Odin. Maybe latest update annoying i know.....no work around yet

The thing is like this: you can always flash roms with EQUAL O HIGHER bootloader version, just that, and NEVER to a lower bootloader version, and this is not new
[Samsung Galaxy Note 8 Questions and Answers] arslan4k1390:
Don't you want to try flashing only AP and CSC_OXM (not HOME)? I read on 4pda that it's possible, but you can have some errors while using your device.

Flash the oldest oreo with bootloader you have, then flash the latest nougat without BL and CP. Only AP and CSC OXM. Backup your data before doing it.

[Samsung Galaxy S7 Edge Questions and Answers] 7UIS:
Hi,

My phone is a Samsung Galaxy S7 edge (SM-G935F) - Exynos variant.

I've been searching around and I didn't find any answer to my doubt. . .So, my question is:

- Does the Exynos variant of the S7/S7 edge (SM-G930F/SM-G935F) have only 2 x M1 cores like the following screenshot shows?

. . .Because I've been using AIDA64 for a while, since I have modified my phone, but sometimes it shows 4 x A53 + 4 x M1 (which I think is the correct one information), but sometimes it shows 4 x A53 + 2 x M1 + 2 x A53 instead.

NOTE: The ROM that I'm using is SuperMan 2.8.0 and the Kernel is SuperKernel 2.10.5.

Thanks in advance.

[Xperia Z3 Tablet Compact Accessories] shaolin95:
Just wondering if anyone has tried a 256GB card with the Z3. I am running Oreo now and it rocks so was going to get a 128gb card to use as internal but well...why not go all the way to 256gb if it works, right? :D
[Xperia Z3 Tablet Compact Accessories] SageDroid:
If your question is still up to date, a Samsung EVO+ with 256GB will work fine. Accordingly, cards from other manufacturers should also work. However, I don't know whether it can be formatted as an internal memory.

I wouldn't do it either, because the SD card is much slower than the internal memory.
[Xperia Z3 Tablet Compact Accessories] shaolin95:
I am running 8.1with the sdcard as internal and while Oreo rocks I do think sdcard is indeed lagging but I thought it could be my slow card. So you mean that reading from any sdcars is slow with this device? Would be a shame since it has the 16GB limitations
[Xperia Z3 Tablet Compact Accessories] SageDroid:
I don't need the memory on the tablet anyway. I tried it some time ago on my Xperia Z3 phone with the app "A1 SD Bench" and the difference was already noticeable.

At the moment I keep it that way, that I have all apps internally and transfer pictures, music etc. to the memory card. My device is running like hell. :)
[Xperia Z3 Tablet Compact Accessories] shaolin95:
I may try that app again to only push bigger data and keep more important apps on then internal. I use the z3 as my daily phone. The way the industry is right now with those horrible (for me at least) aspect ratios 18:9 phones, I won't be buying a new phone for a LONG time lol
[P8lite Q&A, Help & Troubleshooting] dejavecue:
Hello xda,

my cousin owns the P8Lite (PRA-LX1) and gave it to me to attempt unbricking it.

The device is stuck in a permanent bootloop, showing the Huawei logo. When pressing the power button for ~10s, it simply turns itself on again (even when not connected to a PC or the wall socket), which to me is very strange behaviour but I do not own a Huawei device.

I can get to fastboot (https://ibb.co/ixPtAn).

ADB does not recognize the device.

Fastboot does not let me boot a temporary recovery (be it the stock one or twrp), neither does it allow me to flash any file.

I have tried downloading the update.app file onto the root directory of the sd card and force the phone into the update mode (power, vol+, vol- at the same time) but to no avail.

Since it is not my own device and I cannot boot into Android at all, I have no way of getting to the IMEI of the device, which I would need to unlock the bootloader.

Is this device permanently bricked and a lost cause or is there still hope?
[P8lite Q&A, Help & Troubleshooting] badhabitsdiehard:
Hi,

IMEI should be engraved on the lower SIM tray if it's the original one.

HTH
[P8lite Q&A, Help & Troubleshooting] dejavecue:
Oh yes I got the original one. But since I cannot boot, I cannot get the S/N that is apparently required as well.

Edit: Got the SN through fastboot devices.

Now the phone won't accept the unlock code that I got from huawei's website. It still says
[P8lite Q&A, Help & Troubleshooting] badhabitsdiehard:
Hi, sorry for the delay.

Try this, if not already tried: fastboot oem emmc_diag

It should check the status of emmc and tell you if it's ok.

Does this command: fastboot oem lock-state info work on your phone?

And putting the code Huawei sent you in this one fastboot oem frp-unlock?
[P8lite Q&A, Help & Troubleshooting] dejavecue:
Thank you for your comment:

$ fastboot oem lock-state info
...
(bootloader) FB LockState: LOCKED
(bootloader) USER LockState: LOCKED
OKAY [ 0.012s]
finished. total time: 0.014s

$ fastboot oem frp-unlock {password censored}
...
FAILED (remote: password matching failed!!)
finished. total time: 0.211s

It is definitely the code I got from the Huawei Website.

I turned off Auto download on WiFi, but I'm not confident it will stop update to Oreo.

Anyone know if/what I need to do to prevent the update?
[Huawei Mate 9 Questions & Answers] ewingr:
I found in Developer Options an auto system update option that I turned off but it still updated. Dammit!

No help from anyone here either. Maybe it can't be prevented.
[Huawei Mate 9 Questions & Answers] itsjustmeagain:
I have deactivated network access for the app „System Update“ and deactivated the search for updates from within the update app.

Seems to work.
[Huawei Mate 9 Questions & Answers] ewingr:
I'll keep that in mind if it happens again.

Update on turning off updates in Developer options: I have since found this to be what happens after turning off auto update in dev options:

It downloads the update

It puts a notice up that it has upgraded and I need to boot (that was when I posted about it still updating)

But turns out it does not actually perform the update.

It is a bit annoying. I get that notice and it remains in the notifications, even though I have gone in and turned off that notification. As long as it doesn't update, I guess I can live with it.

As it's already downloaded, I'd say your options won't help me at this point.
[Huawei Mate 9 Questions & Answers] itsjustmeagain:
To get rid oft the notification, open Settings » Apps and delete data an cache oft the Systemupdate app. Then continue restricting its network access ( all three options) and notifications. To be sure, disable its ability to change system settings.
[Huawei Mate 9 Questions & Answers] ewingr:
I presume I disable network access under networked apps menu. The only access listed there is mobile. I would think it could still get there when hooked to Wi-Fi.

Do not see an app called update for which to disable search. But I have applied all of your other suggestions, and appreciate your help.

So I have just finished a fresh reload of the original ROM, and now want to trh the command you listed

But I can't get ADB to recognize the phone. I have USB Debugging turned on. I have Hisuite able to see it. But ADB does not see it.

Any suggestions?

Make sure to have ADB USB debugging enabled in Development menu. PC must be granted for debugging (from the phone side).

Ofc, drivers, etc must be installed to the PC - Minimal ADB and Fastboot package (search on XDA) will do
[Huawei Mate 9 Questions & Answers] ewingr:
Problem is, I have already run the delete cmd from earlier in the thread (a reply to my original post here.) Now I need to reinstall. The post I quoted supposedly is how to do that, but I'm getting the errors noted. Going forward I will do it per your suggestion.

Hoping someone can give me correct syntax to revive the update functionality.
[Huawei Mate 9 Questions & Answers] zgfg:
There is no ADB delete cmd - could you be precise and quote exactly the command you originally used?

And the ROGHT commands for ADB re-enabling and re-installing are e.g in my previous post, there are no other 'correct syntax' commands (Google search is also your friend)

If your ADB does not recognize

adb shell cmd package install-existing ...

then something is wrong with your ADB installation on PC or settings on the phone.

Follow the first link in my previous answer and set/install ADB exactly as described in the XDA article

Ofc, if you rooted the phone and you really DELETED hwouc, then you can not reinstall by ADB - but then ADB would not complain that it did not recognize the command but would complain that package did not exist
[Huawei Mate 9 Questions & Answers] ewingr:
Phone is not rooted. And I'm still on the version of OS that shipped with the phone.

Here is the command I used to 'disable' automatic updates, given to me earlier in this thread:

Later in the thread after asking how to get it back in operation to update, I was given this command:

To keep you from having to look back, below is the error I got with that command:

So I changed entry of the command to:

And got this response:

Appreciate your help :)
[Huawei Mate 9 Questions & Answers] zgfg:
Already asked you what is correct command, gave you script Ijust verified before, gave you screenshot where you can see how the command works .

Gave you links - did you read, study, tried?;

Told you that command is ok as in my script, if your ADB on does not recognize command, then something is wrong with your ADB installation, ADB debugging setup on the phone, etc.

SO read that article I provided you and Jake sure you have the proper setup

Otherwise how come that for us the same ADB command works, and your ADB does not recognize it?!

Cannot help you any better, specially if you didn't go through what I already provided you

Did you read the article from A to Z and checked every detail against your PC and the phone setup. Have you tried with Minimal ADB and Fastboot package on the PC (that one definitely supports the command), etc

Run the script I gave you and:

- make the screenshot from the PC and upload

- copy the output of the script from the CMD window, paste to the txt file and upload
[Huawei Mate 9 Questions & Answers] ewingr:
Thanks for all the info...I misunderstood some earlier, my fault. Sorry.

I just ran your script, and it appears that it should have worked. Script capture in the Captured Script.zip file attached.

Maybe I have a different issue. I do not have System Update option on my list in Settings. See screen capture of that. Could that be because I had entered the command of "adb shell pm uninstall -k --user 0 com.huawei.android.hwouc" when I originally was trying to stop updates? Although it appears your script should have re-enabled that.

[EDIT]

Oh, upon full examination of the results file, the uninstall and reinstall of system update both failed. I'd say that's due to the way I had been told some time ago do do adb shell pm uninstall -k --user 0 com.huawei.android.hwouc.

Not sure how to recover.
[Huawei Mate 9 Questions & Answers] zgfg:
I still see in your captured output, at the end:

Uninstall System Update
Failure [not installed for 0]

Re-install System Update
Unknown command: install-existing /

But I see also:

C:\Users\HP\AppData\Local\Android\Sdk\platform-tools>

So asking you for the third time, why don't you try with Minimal ADB and Fastboot - what if your SDK ADB does not support

adb shell cmd package install-existing

as it constantly warns you:

Unknown command: install-existing

Minimal ADB and Fastboot does support that command (again, check my previous screenshot from the PC)
[Huawei Mate 9 Questions & Answers] ewingr:
Ok. You've provided a lot of information, including on rooted phones, etc.

So at this point, what I understand from all of that (so much can be confusing for a non-Android developer) that you want me to do is:

Install Minimal ADB and Fastboot

Be sure Debugginng is on on my phone

Run this command: adb shell cmd package install-existing com.huawei.android.hwouc

I have done that, and I get:

The version of minimal ADB that I downloaded is 1.4.3
[Huawei Mate 9 Questions & Answers] itsjustmeagain:
The pm command install-existing seems to be dependend on the adb implementation in the android version of the phones firmware.

The command has to be recognized by the adb server inside the phone.

My Mate 9 running EMUI 5.0 / Android 7.0 doesn't do it either.

My FP3 running Android 9 does it.

Btw. same adb client version...

It should have been better to use disable-user instead to be able to revert it using enable, which works.
[Huawei Mate 9 Questions & Answers] zgfg:
The point is that [MENTION=717159]ewingr[/MENTION] removed Update by uninstall -k --user 0

and he wants to get it back now

I cannot find in his posts what is his EMUI version - mine is MHA-L29 9.1.0.252 (Pie)

Btw, I also prefer disable-user

because you can usually enable the app back simply from Settings/Apps (if you need and you have no PC around)

However, there is one annoying thing with disable-user, if there is an update for dosabled app on Playstore, it will offer to update and automatically re-emable the app - no such problem with disable-user

Edit: [MENTION=717159]ewingr[/MENTION] - if you just want to update, you could try from the Project Menu (dial *#*#2846579#*#*), eRecovery or HiSuite - the last two definitely may not depend on disabled Update app.

If there is no update, eRecovery can reinstall the same stock firmware (thus re-enabling the Update app back)
[Huawei Mate 9 Questions & Answers] ewingr:
It's interesting to hear the info. Appreciated. It seemed interesting to me that the full version of ADB couldn't do what the minimal version can do. I had ignored installing the minimal version as I presumed that the full version should do anything the minimal version could do. I got dressed down for that.

Re: the EMUI version is the version that came on the phone. Sorry I didn't specify. I presumed that if the OS hadn't been updated, then the EMUI would be expected to not be updated either.

I do appreciate all the help. I will chase down the suggestions you just made and see if I can succeed with those. I will post back my success or failure.

I presume that PIE is not yet available for the L29. Any idea if it is expected to be available?

[EDIT]

Oh boy...I just noticed my sig at the bottom indicates the wrong versions of OS and EMUI. At the time I had started this thread, I had been updated to those versions. I rolled back, and the reason I started this thread was I was failing to keep it from updating.

I'll update my sig, and hopefully will remember to update it again if it changes.
[Huawei Mate 9 Questions & Answers] ewingr:
I just entered the keys to run the Project Menu and try an update. I see that option 4 is Software Upgrade.

When I select that it offers 1 item, SDCard Upgrade. I don't know if that means make some kind of changes to the SDCard, or if it means the upgrade will download to the SDCard and upgrade the OS from there.

Any idea which it means? I don't want to tweak the SDCard if the Os isn't upgrading, Not sure if it will mess things up or not.

I know I've said it, but will again: I appreciate your help.
