See here

There's two elements in play here. First is the Tensor (Pixel 6 / 6 Pro / 6a) platform bootloader for Android 13, which increments a permanent anti-rollback counter in the device upon successful boot of Android 13. Sort of an e-fuse; it prevents rolling back the bootloader. This does not affect previous Pixels, and was implemented because of a critical security vulnerability in the Android 12 bootloader. This also prevents loading older bootloader images.

Second is the A/B slot system, which is the AOSP recommended format for OEMs to use so as to facilitate seamless updates...

Sort of.

There's two slots: A and B. Each slot has its own critical partitions: /bootloader_a, /radio_a, /boot_a, /system_a, and so on. The /data partition is shared by both slots.

The way this works is almost exactly as you described. Let's say the system is running on slot A. When an update becomes available, update_engine can download the OTA package, extract the payload, and write the update to slot B - all in the background while the OS is running. This allows user activities to continue and does not prevent critical functions such as phone calls, texts, etc. Once the installation to the other slot is finished, update_engine prompts the user to reboot. It then sets the updated slot, slot B, as "active" so the device will boot from that slot when rebooted. If boot is successful, the system marks that slot as "successful" so the device will always boot from that slot. From the user perspective, their device is only "down" for a couple minutes while it reboots into the updated slot.

If boot fails for whatever reason - bootloop due to corrupt image for example - it will "recycle" to the original slot so the device remains useable instead of being stuck with a corrupted, unbootable update.

The two come together in what is the problem for the Tensor devices: the OTA method only updates one slot, meaning there will now be an Android 13 bootloader on the "new" slot, and Android 12 on the "old" slot. If Android 13 boots far enough to increment the anti-rollback, but later fails and the device recycles to the Android 12 slot, the device will fail to boot because the Android 12 bootloader has now been locked out by the anti-rollback counter.

The reason this doesn't affect Samsung devices is because Samsung has stubbornly resisted the AOSP model and continues to use a standalone /recovery partition instead of the A/B format. The drawback to this is that the system must go "down" for an extended period of time while the update is installed in recovery, preventing use of the device.
[General Topics] ausganger:
Thanks for the clear explanation. From what I've read in other posts, a second fastboot OTA will install Android 13 on the second slot, preventing a potential future brick. Other posts have speculated that Google might create a compliant bootloader for A12L, but there's nothing official, on that. From where I stand, this issue should have been immediately addressed by Google simultaneous with the release of BlueJay. My current choice is to hold-off on A13 until these types of major bugs capable of bricking a device are addressed. Perhaps the Calyx OS folks will tackle this, as well.
[OnePlus Nord 2 5G] superpascu:
Hi all,

Two things.

I am trying to find the file the phone downloaded to upgrade to A12 but I cant find it. I didn't upgrade but I am sure the file was downloaded. I have tried to find it connecting the phone to the laptop, I have not root (not sure if a I need it)

The thing is that I dont want to upgrade the system to A12 but the phone has already downloaded the file. I would like to delete it. Please note that I have just taken the mobile from the box and I had updated via OTA to the last A11 firmware.

Another question, I also have a oneplus nord 1 and could stop the update app using this adb commands:

cmd

adb shell

adb shell pm disable-user --user 0 com.oneplus.opbackup

But they dont work in the oneplus nord 2. I get the message "inaccessible or not found". Is there any other command for oneplus nord 2?

Thanks!
[OnePlus Nord 2 5G] ze7zez:
The OTA file is located on a partition that you cannot access.

Thanks to the ADB AppControl, it is easier to find services/applications responsible for downloading and notifying about updates.

[Touch Pro, Fuze General] medgirl2001:
I'm sure there is a simple answer to this, but I haven't been able to find it.

I am trying to transfer a ringtone via Bluetooth from my Krzr to my new Fuze, and I can't get it to work. The devices pair without any problem, but when I try to send the ringtone, I get a failed message. This is not a copy-protected ringtone - it's just a music file I created. Is there some trick to this? There are work-arounds (transfer the file to the computer and then to the Fuze), but it is annoying and seems like it should be easy to do.
[Touch Pro, Fuze General] alfredob1:
Did you turn on the Beam function on the Fuze? It's in the Comm Manager.
[Touch Pro, Fuze General] medgirl2001:
I did. It didn't help.

Strangely, I can send files from the Fuze to the Krzr without a problem. But the Krzr can't send anything in reverse.
[Touch Pro, Fuze General] alfredob1:
I haven't tried a phone to phone transfer yet, so not sure what else to advise. I know it works from computer to phone using bluetooth.
[Touch Pro, Fuze General] ExTREmE99:
from my experience the bluetooth on this phone is absolutely terrible. itll connect just fine to my headset. but, i cannot for the life of me sync it up with my phone. bluetooth tethering is near impossible with all 3 of my bluetooth enabled laptops, as well as bluetooth activesync.
[Touch Pro, Fuze General] YellowGTO:
Go under Bluetooth settings under Comm Manager go to FTP Enable File Sharing and then go to security and turn off Authentication (Passkey) Required. You can keep Authentication on with another smart phone but when I wanted to send files from my LG non smart phone I had to turn it off.
[Touch Pro, Fuze General] medgirl2001:
I tried all the suggestions above, but with no luck. :( It's not the end of the world - the Bluetooth works with my headset, transferring files to/from the computer, and for tethering. It's more annoying than anything else, because there's no reason it shouldn't work.

[Samsung Galaxy S21 FE] ish4d0w123:
There is none. Not even for the snapdragon version (which is the better edition imo and better supported by gcam) so the alternative edition (exynos) is out of luck as well.

For some reason this phone does not seem to be compatible with gcam and no one is working on it. Of course people are posting config files and claiming some versions work, but they don't.

It is not a working version if the main lens, or any lens is not usable, or if the viewfinder freezes after 2 seconds or if HDR doesn't work.

Of course it would work without HDR or image enhancing, but that would really ruin the point. The point of gcam Is that it's image optimization let's it make better photos than stock camera. If you disable image optimization because you cannot give it sensor hardware access then it is just a regular camera app, called gcam, nothing more.

[Samsung Galaxy A6 ROMs, Kernels, Recoveries, & Oth] nqnxev:
Magisk modules won't make your phone significantly faster. You have to flash overclocked custom kernel (H-Kernel or Ares Cobalt for example), and some (free of bloat) custom rom to achieve that.

Hello .. Super newbie here, trying to upgrade my Galaxy A6. I have tried endless twrp versions I could get my hands on, but only one actually worked .. 3.2.1-1_ashyx (I currently have no idea where I found that build, but i was successful in getting my A6 to load into it in recovery mode (hopefully my terminology is correct). The problem is that when i tried to put Lineage on it, it gave me the error 255 (that after researching probably means 64 bit vs 32 bit).

Can you help me understand my options? I don't think going over 3.2.1 will work .. again, I tried so many, and I can't seem to find a 64 bit 3.2.1 anywhere. Do I must? Maybe if the twrp i have is 32 bit, I can find a Lineage that is also 32 bit?

Thank you.

[Samsung Galaxy Z Fold 4] fonix232:
Could we please refrain from giving incomplete and barely legible advice that doesn't really help people, please?

@hammody to flash that CSC, you'll need:

- ODIN (latest version is 3.14.4 I believe, you'll have to hunt XDA for the latest version, and it's not yet guaranteed to work with the Fold4 - an update might possibly be needed)

- The appropriate firmware containing the CSC you're looking for (samfirmware or similar sources, https://github.com/samloader/samloader if you're technically adept)

- Possibly a SIM card from that CSC region (this is because your phone will choose the best matching CSC, based on, in order: 1, SIM card 2, Phone release region 3, best/default available CSC if neither SIM nor phone region CSC found)

1. Insert SIM card into phone

2. Flash firmware with ODIN (this WILL wipe your phone)

3. Reboot and wait

The correct CSC should be picked up and loaded, and call recording function should be available. However you _might_ lose features that are in the local CSC.

you can change the csc with samkey! just disabble/remove all sim cards first from the phone, wifi also.
[Samsung Galaxy Z Fold 4] rahul_verma:
there is a better way to call record, you can connect multiple Bluetooth headsets to the phone, however when call is connected only one is active if someone willing to make an app that allows audio split to two different Bluetooth devices, then one can be used to communicate while the other records connected to a dedicated recorder which keeps warranty also and no root

Actually you probly would want to watch for the "Battery Status" Window and then check maybe three points using x,y to verify that the text actually says "Battery is low"...

You could verify that it needed to be checked if battery = 0 before even polling for the battery status window, so you could ignore the battery is full message.
