Is rooting Mediatek chipset devices a bad idea ?

Is rooting Mediatek chipset devices a bad idea ? - General Questions and Answers

Hi,Umm, I have mostly encountered that devices with MTK chipset are going more haywire than SD chipsets could it be that there is no reason for this to be true.I have many MTK devices but now I haven't had them rooted can anyone confirm any method which is less harmful for MTK devices probably one which doesn't destroy motherboard.
P.S Usually I avoid buying MTK based devices also will probably avoid in future as well xD

it is irrelevant which processor is installed in the Android device: Android's version should be 6 and higher

actually, mediatek devices are easier to unlock, raw backup is always possible, porting custom recovery is possible without source code, rooting is therefore always possible, so consider mediatek is less secure than qualcomm or exynos where some devices don't even allow bootloader unlock.
downside, because source code often is not published, development scene has sparely support for mediatek, so often no custom ROM will be available at all.
of course, powerful tools like SP Flash Tool or mtkclient always come with highest risk to brick, it's your responsibility not to blindly trial or follow random people advice without knowing what you're actually doing. read golden rules
- do not flash preloader
- do not format whole eMMC
- do not use foreign scatter file

Thanks for sharing this, I'll keep that in mind
Also I've never flashed Custom Rom on MTK variants though using Xposed and SU must have caused such issue.

Did you actually ran, or did you try to run Format All + Download from SP Flash Tool?
In case you did, that will have erased SECRO which is responsible for verifying DA + auth_sv5.auth. Besides along with other important partitions (IMEI, calibration data, etc.) you lost the availbility to flash.

[Q] About risk

Ok, hello everyone. So i got mediatek phone(Ig l50)
I know that flashing roms with recovery isn't risk(if the rom doesn't work you try another)
but I want to ask :
Is readback with flash tool risky?(Readback is for backing up boot or recovery with my own generated scatterfile)
Sorry if this isn't the right place

You should backup your data first and save it on external device (SD-card, your computer, ...)
After that, you can do anything what you want without worries.

Once you flash your phone OS, phones warranty will be null and void. Save all your data on your computer or use any backup app. Once you have all data backed up, then there is no much risk, even if it fails you can flash it again with different image.

Also it is not just safe. If you flash the wrong rom you can brick your device and as it is a mediatek device you will be hard pressed to find anything. Most developers refuse to touch these devices.

Ok thank you all. but I am asking for readback option, not flashing?

Ill be honest. Only Clones and knock offs generally use this chip so we dont see alot of them here and support none. So You maybe better off looking at a china based forum for the info you need.

[Q] How is it possible to brick a phone?

I'm kind of expert in the PC/laptop world, but a little rookie in Android and smartphones world. I don't get how a phone can get bricked.
As far as I know, an Android device has internal memory, and a portion of this internal memory is ROM (read-only memory), where the OS/firmware is installed. It's ROM because you don't want to mess around changing things of the OS, because you're not supposed to change things of the OS for the sake of a correct behavior of the phone.
The thing is that if you accidentally mess up something in the OS/firmware, you can, or should be always able to, re-install the OS again and start all over again. I mean, if I delete some Windows files in my PC and completely mess Windows up, I can always turn off the PC, turn it on, go to BIOS menu, boot from a Windows CD and re-install it. No problems at all.
1. So... where's the BIOS in Android? The recovery menu in Android is like the BIOS in Windows?
2. Bricking a phone is like damage the software of the hard disk drive (windows) or is it like mess up the BIOS?
3. Is there any difference between Operative System (android), firmware and ROM?
Well, ROM is memory, a physical drive/electronic device, completely different to a program/software/OS, but I'm referring to the conception you guys usually use (wrong I must say).
4. Why is it said that you flash a firmware, and not you install a firmware? Is it because it's done in a ROM, so it's called then flash?
Thanks!

I'm neither an expert in PCs or Android, so I might just be blowing hot air. I think the difference is that with a PC, it's designed to run Windows, thus Windows (obviously) will work on it (depending on version and processor compatibility). Linux runs because it's designed to run on that hardware. With Android however, everything is manufacturer-specific, and device-specific beyond that. If the firmware and kernel isn't written for that specific device, you'll brick your phone.

It could come from either. Flashing the wrong recovery (like TWRP for a Galaxy S3 Exynos instead of a Snapdragon model) would brick, and flashing the wrong ROM would brick as well.

"ROM", in Android parlance, is indeed the OS. Sometimes also referred to as the firmware. Yes, both are misnomers. The use of "ROM" to refer to the OS I think comes from ROM image, when referring to gaming console emulation, but I could be mistake. "Firmware" typically refers to the programming in an electronic device that doesn't have a proper OS, per se. Like a basic mp3 player, VCR, cable modem, microwave oven, etc. It could be argued that Android is indeed a "firmware", by definition, even though "operating system" is more appropriate. Regardless, "ROM", and "firmware", in the Android world, both mean the OS.
4. Why is it said that you flash a firmware, and not you install a firmware? Is it because it's done in a ROM, so it's called then flash?
Click to expand...

Flashing installs, but installing isn't necessarily flashing. "Flashing" is typically done at the recovery level (or through ADB), in the form of zips, tars, and other formats. It isn't incorrect to say that you installed a Gapps package through recovery, or you installed a newer version of TWRP, even though such actions are commonly known as "flashing". However, one wouldn't say that you flashed Clash of Clans through the Play Store, because that's not what you're doing. Flashing can refer to both firmware and software. For example, you can flash apps (like a Gapps package) TWRP batch back-ups, or even individual apps, and these are all software. You can flash nandroid backups or ROMs, and these are operating systems (and software/data). You can also flash proper firmware, such as radios/modems. You can flash kernels. Again, it's not wrong to say you "installed" it, but saying "flashed" is a more appropriate (in the Android community) and specific term.

A BRICKED phone is a phone that can't be fixed,no matter how hard you try.In other words,bricking your phone is altering the OS of your device in a way that causes it to become unusable/inoperable.
A BRICKED phone will not be able to Boot/Display any information/Boot into Recovery Mode.And thus your device turns into a very costly BRICK or Paperweight.
I have never seen any BRICKED device but heard about 2-3 cases here on XDA.I guess there are slight chances of getting your phone bricked until you do something HORRIBLY wrong or you do something,you don't have any idea about.
AFAIU,following factors can lead your device to BRICKING.
1.Overwriting the Firmware of the device or System softwares.
2.Interrupting Firmware update process (Half-written firmware ).E.g. Your device loses power during the process/data cable is pulled out during adb or rooting (That's the reason you get notifications or warnings as “Do not power the device off” when performing firmware updates and "Make sure your Battery is charged")
3.Flashing a ROM/MOD/Kernel that's not compatible to specific Device and Carrier.
Hope this helps!!

That being said,
To my understanding so long as you flash your phones specific Kernel after flashing a carrier-incompatible ROM you will not BRICK. That is the only time I've bricked a device. It was an S3 and after 3 days of research I learned an SD card can be used to bring it back to life by basically flashing your .img onto it, albeit I could never boot the device without it again, though I could take it out afterward.
It was strange... but since using that device as a learning toy I believe that is something I learned from the experience, but correct me if I'm fatally wrong please before I get someone in trouble.

Short answer: If you can boot into Fastboot Or Recovery mode,you are not Hard bricked and there is still some hope
The scenerio you are talking about is Soft Brick.In this case your device don't boot but you can still get into Recovery.To fix it you boot into Recovery and restore the backup / flash the system image.You don't need to flash a kernel to make it working.
A hard bricked device won't show any sign of life,you won't be able to boot into Fastboot or Recovery to run Fastboot commands / ADB shell commands / Flash any image or zip.
Hope this helps!!

Plug out your Phone on flash Befor he finish boting

I totally understand what you're conveying and trust and believe when I say I've had my fair share of both types of Brick. What I mean is.... essentially the Kernel is going to be the defining difference between Hard Bricking vs Soft. For instance, I'm using a Note 5 Sprint (SM-N920P). If I were to flash BlahRom_N920T.zip then try and boot to system it'd definitely Hard Brick me, but if I were to flash an N920P Kernel immediately afterwards THEN boot to system out wouldn't. It might be kind of jacked up and buggy, but that's the determining factor as far as I understand.

Thoughts about soft and hard brick ?!

HI there.
i read this :
Soft Brick
Soft brick is the state of android device due to some software problems like bootloops or device freezing at some point during boot. This may occur if some software problem occurred in the device mainly during OS upgrade or flashing something such as a custom ROM, camera mod or app in your custom recovery mode. A soft-bricked device is only half-dead. Because of this, your device is not booting anymore or is constantly crashing but can be recognised by a computer.
When your phone is soft brick, don't be panic. You can revive your Android device as long as it is only soft-bricked. The basic solution for this issue is flashing a clean and working version of Android to your device. While, during this process, you may need to restore a backup, flash a custom ROM or stock images to your device.
Hard Brick
Hard brick is the state of android device that occurs when your device is unbootable without a bootloop. A hard Brick device generally show little to no signs of life. If this happens, you had better to buy a new device since your device is showing you a black or grey screen at this point.
A phone get hard-bricked due to trying install ROM not made for the device or use ROM Manager incorrectly. Hard brick is more difficult to resolve and you may require an expert to give you professional advice. However you can recover from hard brick by using JTAG or send your Phone to JTAG service center to get it fixed, which means you no longer need to buy a new one.

Is it true that even hard bricked device can be high percent recoverable?
I own service and want to know the things good and be normally good. If i have to i will take loan to buy nessesary stuff to be successful.
Is that with JTAG true for tablets too? I have buyd from AliExpress Phone Box 2017 version but still havent used it.
If i have to be more specific. Have one client`s tablet here. It is recognised by Windows as MTK something and gone after seconds from device manager then recognised again and that...
history : it was virused and install OS to it was really needed. I shot in the dark and install it some OS for these parameters:
mt6582 1G+16G and flashed it successfull with SP Flash Tool but now the device does not boot and is half recogniseable in Device Manager. I did that because the device/'beauty' chinese tablet/ has no ID on the back side of it.
I hope this time someone to tell something good and usefull.
Thanks

Yes, it is "possible" to recover hard bricked devices with a JTAG but there are no guarantees it will work and no way to guarantee each customer that there device will be fixed.
As for the MTK device you are trying to repair, you can't just flash a firmware from another mt6582 device, there is quite a bit more involved than just the same CPU. Firmware from another device must be ported to work with the other hardware on the device.
You need to identify more about the device than just it's CPU if you want to find a firmware that will work without modifications.

Can you give me a link to the seller site?
Usually these cheap off branded Chinese tablets are almost impossible to identify properly because the hardware varies so much even among separate devices with the same model number. It is like this because there is no actual "manufacturer", these devices are pieced together with cheap discounted components that were bought in bulk and they use whatever they can get to work, even if it involves using completely different components. This makes it virtually impossible to say exactly which firmware you need.
When a device is bricked and the device is one of these cheap devices that can't be identified properly and has no available stock firmware or stock source code and has no support from the manufacturer, typically, the only solution is to just try different firmwares and hope one works or piece together your own firmware with pieces of others that might compatible.
You'd have to have a lot of time and android development skills to make your own firmware.
You've got a difficult road ahead, I'd suggest they replace the device because the cost of repair will be more than the device costs.
When you flashed the device with SP Flashtool, did you happen to pull anything important from the device or did you by chance make a backup of some sort before you flashed it?

Man usually understand his mistakes after he did it.
Maybe I will never take again unknown tablet for service. The problem is that the customers are waiting and I am tired of buy customers devices either second hand or new.
The site should be 4sales.BG
That said the woman.
The 'cool' is that I find there version not with 1g+16g
Good night.

In simple words, Soft brick is messing a little with your Android from which you can recover easily.
Hard Brick is like screwing up your device completely, yes, you can recover, but it needs lots of technical process.

Technical or not that`s not bad. Just want to have the nessesary tools if they are not too expensive. I just wont desolder very very small smd resistances and transistors
If someone can help in my chinese tablet case i will be a little more not unhappy.

[HELP] Redmi 9 Hard Bricked

Hello i've flashed a custom ROM for my Redmi 9 this morning but it failed.
Now my phone doing a big f* bootloop, the recovery (TWRP) is dead and the fastboot too.
I've found a tool named SP Tool to repair the phone but the problem is when i plug my phone to my computer the phone is charging (logic) and instead showing the animation of the battery it bootloop until it runs out of battery.
So someone can help me please
Thanks
Edit: Oh i forgot, now i've realised than when i flashed the rom i've wiped the entire phone (internal storage too)
My bad...

Is your device Merlin or Lancelot? If you're not sure, what processor do you have, Qualcomm or MTK?
If it is Qualcomm, try test-point method to access EDL mode, then use Mi Flash Tool to flash MIUI on your device. Read this FAQ to learn more.
If it is MTK, then follow this guide and download the tools used in the video from here. You can find your device ROM (Lancelot) here.
Just make sure you're flashing global version if your device is global or chinese if your device is chinese.
If you're not sure what you're doing, I highly recommend sending it to a professional.
Goodluck.

Both SIM slots have no IMEI? I assume you wiped all and didn't backup?

This tool installs the driver required to unbrick your device, if you can find your device specific driver to install on your PC then you can skip using this tool and install the driver manually.
If you can't find the driver, then try using a different cable when connecting the phone to the PC. Or a different port in the PC (Like the legacy 2.0 USB port in the motherboard).
The tool should first detect any device connected to install the driver it doesn't work the other way. If it still doesn't work then your only option is to find the driver manually. Or maybe you can find an updated version of the same tool or a similar tool.

Might be a random guess but it could be because signature protection was enabled on the win 11 PC.

Do you have a bootloader locked or unlocked? (here to know how)
If it's the 1st option, relax, you can modify easily
If it's the 2nd a little bit less
NB: i don't use really use this phone, just for developpment and some things than it can break the OS because it had some problems with apps and updates.

Whatever now I've getting issues that weren't there before hard brick. My redmi doesnt recognize my Sim card. I enter my pin security and then don't get any sim card signal. Also can't log on play store with my Google account, i get this message "there was a problem communicating with Google servers, try again later." Tried to wipe Google play services data, also from play store, formated redmi from recovery but the problems remains. Maybe i need to reinstall rom again, im pretty sure it was the right rom i flashed because i download it from miui official website. Unfortunately after reviving my redmi with sp flash, my bootloader got locked again. Sense i cant log with Google account because phone doesn't recognize my chip to activate data sim card, i cant either unlock with mi unlock. Is there any solution for this? Thanks.
Perhaps flashing phone with another rom the problem gets fixed. I can still flash my phone with sp flash even with bootloader blocked right? My redmi comes with a European rom. To revive him i used rom last update, maybe should try a previous version?

Are all the steps performed with the phone turned off and connected to the computer?

Are MediaTek 6563 and 6567 ROMS interchangeable?

I have an RFinder B1+(14) that works fantastic, it has the 6567 chipset. I also have an RFinder B1 Classic with a 6563 chipset that will not boot into Android 8 on the way, and the ROM has not been easy to find.
I suspect they are NOT compatible, but if I did flash the older radio with newer firmware, I'd be able to reverse the damage as long as I didn't overwrite the preloader.
If the two are, in fact, compatible, it would save me some time.
Are they compatible?

Not without porting them from one to the other, "IF" the sources to do so are available(either stock firmware for the two devices or at least the stock source code for the device the ROM will be flashed on.

I have tried without success to compile software. Of course it can be done, I just haven't got the hang of it (I need to learn though).
If there are other things I can do, learn, etc from this thread, I'm all ears. If not, thank you for the info.

There really isn't a 100% all in one get it right the first time guide out there. There are lots of guides that give a general idea of how to port stock ROMs but it will still require trial and error to iron out the details. Do some research to see if there are any specific security features preventing the ported ROM from flashing/booting then see if there are any tricks to bypass those specific features. You may need to unlock the bootloader and dig into trying to modify the bootloader.img located in the copy of your devices currently installed stock firmware file(or the last "official" firmware that was installed on your device before you tried to modify it).
