Hello @er842 ,

Were you able to accomplish the downgrade?

This S20U user did.

OP, what apps weren't compatible?

[Galaxy Tab 8.9 General] apun333:
I have 2 of these tablets (Model: I957D & I957R), both are on stock 4.0.4 and no apps work on it, I just want to download youtube on them for the kids and maybe couple basic games. I just found a thread about rooting the tablet on these forums, after rooted is there any customer rom I can install to be able to download youtube etc... any links to custom rom would be appreciated, hoping to even get Android 5.0 or higher, but I believe Youtube still works on 4.4 ? Any help will be greatly appreciated. TIA
[Galaxy Tab 8.9 General] Scorpionish:
You don't need root/custom rom to watch YouTube or update. Find a suitable DLNA receiver or casting application for your tab, then download Web video caster on your phone, 𝗰𝗼𝗻𝗻𝗲𝗰𝘁 video web caster with 𝗿𝗲𝗰𝗲𝗶𝘃𝗲𝗿/𝗗𝗟𝗡𝗔. Browse 𝗬𝗼𝘂𝘁𝘂𝗯𝗲 video on phone and hit 𝗖𝗔𝗦𝗧. It works with for any streaming service not just YouTube.

2 days ago my display start to flickering (constant small horizontal line flickering) all over the screen.

What i have done is

1. wipe cache partition

2. restart

3. safe mode

but no luck.

during startup boot, recovery mode or optimising app no flickering seen.

Never had this before (Android 11). after 3 week updated to Android 12. this issue happen.

is it probably Firmware issue? currently im on G988BXXSCEUL9 XME (Malaysia)
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] blackhawk:
Try using different fixed frequency display rates and brightness levels.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] apecx92:
Tried turn off adaptive brightness

Change from 60hz to 120hz and back to 60hz

Turn off/on night light

Eyeshield off

Screen mode to natural

Resolution to 1080 and 720

No luck.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] blackhawk:
Guess try reflashing it. If you can downgrade do so. Maybe a mobo failure, if a downgrade solves the issue... leave it there.

If under warranty, send it in.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] apecx92:
its not underwarranty anymore. tried factory reset also no luck.

does reflashing remove my esim carrirer data?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] blackhawk:
Not sure as I haven't had to do it. I rarely mess with the firmware if it's running good even to do updates. This N10+ is still running on Pie, the current load will be 2yo in June.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] apecx92:
Alright thanks for the reply. I will just wait for next update hopefully it will fix. Otherwise i'll just buy new phone
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] blackhawk:
Not written in stone. Maybe a loose connector or it got corrupted doing the upgrade. A Samsung Experience center at a Best Buy might be able to find the issue and if firmware, reflash it.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] apecx92:
I downgraded back to Android 11 Nov 2021 build using Odin (my esim data doesnt get erase).

no more flickering screen after 2 hour of usage, i will keep monitor the display and update here again.

Hopefully its the Android 12 Firmware issue not my hardware.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] blackhawk:
Could be either or a combination of both. Best shot is to not update/upgrade it again. It can run for many years like that.

Android isn't PC and anything from Pie up is reasonably secure as is.

With 11 you have more than enough security in place unless you do something stupid... which is how malware usually gets loaded.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Im_naufal:
Hi

I'm having the same issue in my s20ultra exynos G988b/DS and it's nearly 2 years old and in clean condition. got this problem last week and it wasn't under the warranty anymore service center said it was hardware and need to changethe display which cost ~$290 which i refused since the device is not even scratched and pretty sure must be a software thing.

Came across your post today, can you verify that problem has gone after the downgrade?

Thanks in advance.

[OnePlus 8T Questions & Answers] FakeGemstone:
I have an 8T-KB005 device and I'm trying to get OxygenOS ver 11.0.11.11 KB05AA synchronized on both slots.

Using the copyPartitions.zip failed;

Installing a full OTA twice using Oxygen's built in updater kinda worked but it created 3 additional "cow" partitions;

Installing OOS to both slots through TWRP failed; and

trying to install OOS using the manual fastboot method failed.

With regard to the "cow" partitions, I deleted them and found I was again not able to boot from both slots. I went though this process three times just to check and the outcome was always the same. (Does the on-phone update process create these -cow partitions for everyone?)

At one point I used Fastboot -w to clear everything then start fresh. I have found that if I delete, then recreate, all the logical partitions on both slots, then *sometimes* all 5 logical partitions will resize when I flash system, vendor, product, etc. image files and then I can boot to system from that particular slot, but then the logical partitions will NOT all resize when I switch to the opposite slot and try to do the same. This is the error message I get when I'm using the fastboot method:

C:\xxx\xxx>fastboot flash system_ext system_ext.img
Invalid sparse file format at header magic
Resizing 'system_ext_a' FAILED (remote: 'Not enough space to resize partition')
fastboot: error: Command failed

I can currently boot to system on one slot and get a Qualcomm Crashdump kill init error when I try to boot to the other. I could use the phone pretty well if I had to with just one slot operational but if I don't fix it this issue will eventually come back to haunt me.
[OnePlus 8T Questions & Answers] Fif_:
Which instructions did you follow for flashing from fastboot?

These worked for me: https://xdaforums.com/t/oneplus-8t-rom-ota-oxygen-os-repo-of-oxygen-os-builds.4193183/post-85466569

Pay attention to the fastboot delete-logical-partition commands (which have to be issued in fastboootd).

I've seen the OTA updater create temporary partitions that were not ending in cow, so check out for other partitions that may have been left over from the last failed update.

You may want to try deleting all logical partitions and recreating them with small sizes. You can definitely remove all logical partitions that contain cow in their name.

I've attached the output of

fastboot getvar all

with the device running fastbootd. It contains the stock partition layout for the latest US firmware installed with the full OTA on both slots.
[OnePlus 8T Questions & Answers] FakeGemstone:
I followed the write-up from xstefen and also this one from coomac, both very good. They say the same thing but combined they give a lot of detail.

As per their instructions, I always deleted ALL logical partitions and then re-created the a/b ones. But looking at the text file you sent to me, I see that one has 3 of the cow partitions. Interestingly, every time I did an OTA update on my phone I ended up with 2 or 3 of the cow partitions, but not consistently the same ones. I've spent very much time over the last 2 days scouring through the output lists from fastboot getvar all trying to get to the bottom of this.

This is what I have been doing but as I stated, it results in not being able to boot on one or the other slot. On the other hand, because the creation of the cow partitions is unpredictable, even when using exactly the same OTA update file, I am reluctant to just rebuild all 5 of those partitions in addition to the usual one as listed in the instructions from xstefen and coomac.
[OnePlus 8T Questions & Answers] Fif_:
The instructions in the thread you linked look good and seem equivalent to the ones I linked.

Another thing you can try is to flash a downgrade package for OP8T, following the same instructions.
[OnePlus 8T Questions & Answers] FakeGemstone:
Thank you, Fif_, for your replies and for providing the text file. All of it gave me some clues to follow up.

I beat this problem to death over the past couple of days. What I learned during the downgrade-then-upgrade process gave me a better understanding of what's going on with the logical partitions. I posted my conclusions on the thread I referenced above. I hope it helps someone.

[OnePlus 8T Questions & Answers] BillGoss:
Have a look at Thread '[GUIDE] Introduction to the OnePlus 8T - Why is it so?' https://xdaforums.com/t/guide-introduction-to-the-oneplus-8t-why-is-it-so.4380349/

Especially the references at the bottom of the post.

It should help you understand how updates get performed and the role of logical COW partitions in /super (they enable a failed update to roll back to the previous working system and are only used in incremental OTAs).

PS: you can also use /system/bin/lpdump -a to see what's allocated in /super. You may need root permission to do this.
[iQOO 7] Myonlineportal1:
Suddenly My Device is creating a issue regarding Sound then i go to iqoo service center they wipe my phone data and reinstall the firmware , after the problem solved a new problem was created regarding NFC . i use a App called All tap & Gpay for payment via NFC in my Iqoo 7 but after reinstall firmware they didn't worked, my NFC is working but they didn't work with my apps ,i attached a file containing the error showing.
[iQOO 7] nikhilkaushik:
This could be happening due to some app integration bug that's there in Android 12.

Or some app bug as well. It is unlikely that if the same version of OS had the functionality working, it's not working post a wipe.

Either app bug or an OS upgrade could be the issue IMO.
[Essential Phone Guides, News, & Discussion] MarSOnEarth:
This boot.img is for end users who would like to flash A11/12 custom ROMs on their PH-1s. It solves/bypasses the problem with GSI ROMs loosing WiFi after being rooted with Magisk.

It comes from compiling the Essential AOSP repo and it is signed by Essential's verity key. It's been patched with Magisk 23.0 and with MagiskHide enabled, the ROMs passe SafetyNet (tested with OctaviOS 2.9 (A11) 3.2 (A12), DotOS, and Corvus).

Happy ROMing

TL;DR: Noob needs to stock flash a device that won't boot into OS.

Here's how the recovery looks (without and interaction):

View attachment 5527751

Boot loader:

View attachment 5527753

Splash screen:

View attachment 5527755

I have acquired a YB1-X90F that just shows the orange Lenovo splash screen and or a blank and does nothing.

I'm a novice when it comes to flashing, etc.

I can access Fast Boot and Recovery Mode.

What should I be trying?

I've got several links I'm going through but I'm rather confused. For example, I've been trying to set up ADB, Fastboot and Drivers. Struggling with drivers.

My first setup was with platform-tools_r32.0.0-windows.zip but I'd just have a missing 'Cherry Trail Tablet' driver in Device Manager.

I then tried 15 seconds ADB Installer v1.4.3 but still no driver. 'Cherry Trail Tablet' in Device Manager.

I also tried ADBDriverinstaller.exe and IntelAndroidDrvSetup1.10.0.exe.

I looked through this thread, but no joy:

https://xdaforums.com/t/missing-usb-driver-cherry-trail-tablet-while-on-bootloader.3537008/

In the end, I had to manually add 'Android ADB Interface' as mentioned in the 15 seconds ADB Installer v1.4.3 page under Notes:

[OFFICIAL][TOOL][WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer v1.4.3

15 seconds ADB Installer v1.4.3 ADB, Fastboot and Drivers What is this? This is All-in-One installer for 3 most needed PC tools for Android. No need to download big SDK for 3 small things. I originaly made it for my Kurdish friend AnGrY DuDe in...

Honestly I am just trying to give everyone a stable, easy to flash build until official drops. I keep source up to date, I have made some of my kernel changes etc.. This is not my great return.
