[OnePlus 10T 5G] kinglove1211:
I have the super image from the global 9 pro uploaded in the morning. It is from the f20 update
[Xiaomi Poco F4 (Munch) / Redmi K40S] binary**#:
True to my knowledge, if the Rollback Index of the Fastboot ROM is less than the current device rollback index, then we cannot flash that ROM as it will trigger Anti Rollback Mechanism, which might end up hard-bricking the device.

In my case as well, my Poco F4 running Android 13 has an ARB of 1 whereas the Android 12 Fastboot ROM that I have has an ARB value of 0, so this means downgrading should not be possible.

However, I have seen across other Xiaomi device forums on XDA wherein users did manage to perform a downgrade simply by flashing the downgrade firmware via Mi Flash Tool.

So is there something specific going on with Poco F4 or I'm missing a point there? Any insights on the same will be highly appreciated.
[Xiaomi Poco F4 (Munch) / Redmi K40S] Alfian Febian:
Don't worry about downgrading OS version from 13 to 12, you just need UBL... and you can flash ROM from anywhere, global, EU, Thailand and more.

Jangan khawatir tentang menurunkan versi OS dari 13 ke 12, Anda hanya perlu UBL ... dan Anda dapat mem-flash ROM dari mana saja, global, UE, Thailand, dan lainnya.

[Xiaomi Poco F4 (Munch) / Redmi K40S] binary**#:
Well, this is what I knew in theory as well. But in practice that doesn't seem to be the case. Aa far as I know, you could only flash a ROM if its Anti Rollback [ARB] Index is equal to or greater than your device's ARB.

And after updating my Poco F4 to Android 13, its ARB is now 1. On the other hand, all the Fastboot ROMs that I have tried to date [Android 12, Android 13, Global, India, etc] have the ARB 0 and hence they all refuse to flash due to the rollback index. Just to be double sure, I took the risk and proceeded ahead to flash them, but the Mi Flash Tool straightaway refused it due to ARB.

So is there any other way out of getting this job done? Because as of now, I could only go from one custom ROM to another, but cannot flash the stock Fastboot ROM. [And yes, my bootloader is unlocked throughout the process].

Hi guys, I'm noticing that when I receive or make a call from the car, the sound of the person I'm talking to is very low, but she can hear me perfectly.

Hi everyone,

I know this might sound stupid and a bit newbie but I got a bit confused and lost while browsing through the various articles out here and want to avoid repeating my past experiences (phone bricked, weekend lost recovering the phone, backups) so hopefully someone can help me out with a brief overview of the required steps.

I'm running:

- latest OOS12

- Magisk

- Shamiko

- Universal SafetyNet Fix

- installed the older OxygenOS updater so that I can upgrade again using local files

May I ask what is the safest way to upgrade it to OOS13 without bricking it and still having it rooted?

What would be the steps? (do I need to remove magisk altogether, do an OTA upgrade, refetch the boot image, patch it, reinstall magisk, reinstall Shamiko and the Universal SafetyNet Fix ..in case something new did not pop up and needs adding also)

Thank you!!
[OnePlus 8 Pro  Guides, News, & Discussion] Deavy:
Exactly ;)
[OnePlus 8 Pro  Guides, News, & Discussion] skyraven83:
:(

no nice way like just applying the update on top without removing magisk & co and redoing it all from scratch, right ? :)

(like a version minor update style where I just installed the update, did not reboot, reapplied with magisk the rooting patch and all was nice and cosy :) )

Hello friends. I need help. Black Shark 4 is my phone. Normally it uses 8 cores, 870 CPU. But 2 months ago, 4 cores became useless without anything. Not active at all. I formatted (hard reset), made China rom via ota (now China A0). Previously H0. My problem is that 4 cores don't work at all. Never. Please help me. I searched for reballing, but when the phone is completely turned off, it needs to be reballed. My phone is working. Only 4 cores are not working.
[General Questions and Answers] karenmcd:
Hey ya'll!

Been running snooping around the xda forums for a while now (2017?), and even compiled lineageos for myself last year for the first time! Gots a question not phone related though. (o:

I have acquired a sony alpha 6500, and it still has the original firmware on it that it shipped with when it was new (2016). I'd sure like to save that before updating to the newest one, as it seems it could have some value for developers as well as for historical/museum value for archive.org. It seems like it's android based as some of the documentation I was reading suggests that opening an android shell might be useful to me, which I've never done/don't know what to do with.

Some folks have had some success with this tool: https://github.com/ma1co/fwtool.py . I did run the tool with the "--help" command, but it didn't offer any insight to the switches that are available or how to use them and I can't seem to find a manual for the fwtool. I think this is the tool I'm supposed to use to get the camera to give up everything that's on it right now, but i don't actually know.

This site won't let me make an account right now to ask for help: https://www.personal-view.com/talks/discussion/12756/sony-alpha-hacks-talk/p11 which seems to be the developer of the software that fwtool.py is a fork of possibly? It didn't have any information about how to use the flags/switches for the app either. That's why I'm asking here

Is anyone able to explain from this information I've found so far what command I would need to run (from linux terminal or windows cmd/powershell) or if there are additional steps needed in order to save or backup the current "ROM/OEM Firmware" that's currently on the camera? Or point me in the right direction?

Thanks! :unsure:

I am having a non-smart LG T.V and unfortunately,I can only use it,if I download movies from internet onto my mobile device and transfer them to a USB device (Flash drive) which is really cubersome and sometimes even the format wouldn't be supported.when I directly connect my phone to the T.V using a data cable, and give it the permissions of file transfer (from my device),It prompts that the USB device isn't supported, probably because it uses the NTFS (read-only) which the Android devices don't support, so is there any method that i can use my Android phone as an usb drive that a non-smart tv can detect as a Read only device, also,if this was possible, could we cast our phone using the same method, like the Android device creates a video file ,being continuously written with the screen cast(even if there is a bit of delay)

UPDATE (11-JUN-2023):

sim-unlock.net is SCAM

A member here at xda advised me to try sim-unlock.net as he used their services many times before.

Long story short, I paid them €42 since 2 months and they scammed me. They didn't unlock nor refund me and they stopped replying to my emails.

I advise anyone who see my post to not use this website. It's a SCAM.

------------------------------

I bought a new s23 ultra from ebay but it's locked to Spectrum. I live in Ireland so I can't buy a spectrum sim and use it for 60 days so that spectrum would give me the unlock codes.

Do you know any *trustwothy* website that would unlock it?

Thanks
[Samsung Galaxy S23 Ultra] cledee:
OP if it was paid off in full, the seller should be able to get the unlock codes for you through Spectrum.
[Samsung Galaxy S23 Ultra] mghool2004:
Really?!! I didn't know about that. Where can I read the rules stating this?

I find that weird because unlocking is legal!

Also, I searched for similar posts before I post this and I see another post 1for a member who offer T-Mobile network unlocks :/
[Samsung Galaxy S23 Ultra] mghool2004:
That's what I understand too. That I have to be on the network for 60 days.

Do you know if I can ask spectrum to sell me an esim online while I'm in Ireland to go on a 2 months bills just to get it unlocked?
[Samsung Galaxy S23 Ultra] mghool2004:
Then I believe it's fine because I just bought the device brand new and it's even still SEALED!

I don't want to unseal it till I get this unlocking process settled.
[Samsung Galaxy S23 Ultra] cledee:
They can call and request a temporary unlock for travel. Have the seller call Spectrum and request a temporary unlock and say that they are travelling to Ireland for work for 60 days.
[Samsung Galaxy S23 Ultra] mghool2004:
So, I can use my non-spectrum in Ireland for the period of those 60 days?

Then what? get locked again with no excuse this time? :/
[Samsung Galaxy S23 Ultra] Talderon:
The other issue is that a vast majority of the Unlock Services out there are scams, and XDA should not support those sites, links to those sites and discussions of those sites.

It's too much of a slippery slope and, honestly, for a Mobile Dev Forum, unlocking is not a subject they should get into.

Now, i am just talking about SIM unlocking.
[Samsung Galaxy S23 Ultra] zeroktal:
Spectrum will issue you an unlock code if the device is paid in full. You need to tell them you are moving it to another provider.

My roommate did it just last week.

[Samsung Galaxy S20 FE Questions & Answers] jrdef:
So I never posted here but I usually pass by some topics so sorry for any mistake in creating this discussion. Today I deleted some stuff from my S20 FE and downloaded via OTA the march security update in my device, then I was caught by surprise when saw it restarting more than once, instantly I panicked cause this happened years ago with another cellphone and I was like "oh no, not again". Unfortunatelly I'm a idiot for not backing up most of my files over the last year and now I really want some suggestions of you guys for solving It and possibly without losing any data cause there are so much important things. I saw something about using Odin to unbrick It, but I'm afraid it delete everything. I'm not a newbie, I usually did custom ROM my other phones and stuff and once I managed to recover some stuff using adb pull as far as I remember.

Important information:

- It's the snapdragon variant with 4g and Is running the latest update of Android 13

- Apparently Is soft-brick, the cellphone can go to download mode, but I couldn't make It go into fastboot

- When I manage to do the stuff to go to fastboot, appears the android robot loading something, It goes to 100% and bootloop again

- It is detected by the PC, but It isn't listed as a acessible storage neither It files

- Only way to turn It off Is discharging and with a lot of restarts It's heating a lot

Please, I beg for help! Anything might help!
[Samsung Galaxy S20 FE Questions & Answers] ze7zez:
For modern Samsung phones, there is only download or recovery mode.

If you're trying to get a fastboot mode that doesn't exist, you're going to hit strange places.

Try a 1-file firmware flash in Odin. Perhaps the data will remain intact.

You absolutely can't use 4-file firmware for flashing, because you will definitely wipe everything from the phone.
[Samsung Galaxy S20 FE Questions & Answers] mezacorleehone:
there is a way that I have not tried on a semi-breick.

using odin,

BL

PA.

CP.

CSC_HOME.

(MUST BE CSC_HOME NOT THE NORMAL CSC)

So it doesn't format the internal storage. It is as if you updated via ota.

Go into download mode and follow the procedure.

look for the system identical to that of the ota or a version earlier.
[Samsung Galaxy S20 FE Questions & Answers] mezacorleehone:
I update my cell phone like this, I never get the updates by ota,

so under the most current system, I open odin.

I put everything in its place, the CSC_HOME is the one I use and not the normal CSC.

This makes it only update and does not delete anything, as if it were an ota.

I did it recently from the January to February patch.
[Samsung Galaxy S20 FE Questions & Answers] jrdef:
excuse me, but what's a 4-file firmware? My principal concern is about the software I''ll flash, cause the one that got me a problem was a security patch of 1gb of content, and when I download the last one in these sites is a 6gb file apparently listed as the same date I got, so I kinda confused If it screws one and for all. Other thing I was thinking about It's if It's possible to use any adb command like adb pull or something, principally cause I'm afraid I couldn't manage to install a 6gb file because the device is short in storage

So I searched for the last one, couldn't find the 1gb security patch cause It's only available a 6gb but with the same date as the one I instaled via OTA. Well, my concern is that I don't have these 6gb available in my device, and I was thinking about the adb pull command, I haven't tried yet adb commands at the moment, but It was the solution I used years ago in a Motorola device and managed so rescue most of my files, do you think It's an option or there Is any other way I could manage to get some available storage to install the firmware via odin or even try to "naturally" unbrick It, cause maybe the problem It's beeing caused by insufficient storage, right? Only thing I know It's I am hella anxious about It
[Samsung Galaxy S20 FE Questions & Answers] mezacorleehone:
hello colleague a way of not losing anything. It's how I describe it to you. download system 6.44 gb android 13. it can be current patch or a previous one. you load the whole system by odin and you must put CSC_HOME not normal CSC.
[Samsung Galaxy S20 FE Questions & Answers] mezacorleehone:
It doesn't matter if you have 1 GB of internal storage.. odin will only update the system. It will not integrate the 6.44 gb of the system .. only what is necessary to update without losing mada
[Samsung Galaxy S20 FE Questions & Answers] jrdef:
Thanks. I'll try it, don't know If I can because of the insufficient storage, but let's see It

Thanks a lot for responding and helping me, at the moment we all get kinda nervous, but I'm positive about It will work out all well. Later I'll post results

So what's a 1-file and 4-file firmware? The one I download does have AP, BL, CP CSC, that would be an 4-file firmware for flashing? I saw this information about https://android.stackexchange.com/q...msung-4-filesrepairing-firmware-and-single-fi

Well, about the 4-file, there is problem of wiping everything even if using CSC_home? Some research and other response told It would not, but what's your opinion about? Btw, I appreciate the effort to help. Thanks.
[Samsung Galaxy S20 FE Questions & Answers] ze7zez:
Using firmware.zip containing 4 files will clear the partition before flashing.

Therefore, the suggestion to upload only CSC_HOME may not solve the problem described in the OP.

There may be data loss, although this is not certain.

If you find reliable information from some user that the data will not be deleted, then the risk of data loss will be less, but it will be there nonetheless.

Since you don't have the ability to run the phone in download mode to wipe the cache partition, the only sensible choice to revive the phone is to renew the partition with 4-file firmware.

Please treat my post as advice and not as an oracle.

You will have to make the final decision on the course of action yourself.
[Samsung Galaxy S20 FE Questions & Answers] mezacorleehone:
Hello colleague.

Well, for my part I tell you that you comment wrongly.

I update security patches by odin.

It's already 3 times that I update by odin only the patches and it doesn't delete anything at all.

I use the 4 files, have you ever done it or do you just comment it without having done it?

I repeat the procedure

open odin and load the files like this.

BL_G781USQU9HWB2_G781USQU9HWB2_MQB61904472_REV00_user_low_ship_MULTI_CERT.tar.md5

AP_G781USQU9HWB2_G781USQU9HWB2_MQB61904472_REV00_user_low_ship_MULTI_CERT_meta_OS13.tar.md5

CP_G781USQU9HWB2_CP23675490_MQB61904472_REV00_user_low_ship_MULTI_CERT.tar.md5

HOME_CSC_OYN_G781UOYN9HWB2_MQB61904472_REV00_user_low_ship_MULTI_CERT.tar.md5

Until now, when the odin process is finished, my s20 fe turns on and a screen appears

like the one I will upload.

I am giving a possible solution to the problem that he asks for, let's hope it solves his problem.

If the system continues to give problems, it would be to look for another alternative.
