[SOLVED] Help on Redmi 6A (Cactus) Hard Bricked - Xiaomi Redmi 6A Questions & Answers

Hi, I'm new to the forums.
Back to July 2020, I tried to install custom ROM for my Redmi Cactus and it has no problem until I wipe the data from TWRP and install the custom ROM but failed, I couldn't remember why. And now the phone is dead, it won't boot, no vibration what so ever, when I charge it the LED turns on but when I plug it to PC it won't detect the phone, no sound and nothing in Device Manager even though I have the MTK driver installed on my PC. I've read this thread and couldn't understand the first step as it says "Open REV4 Bypass tool, off your phone. Click BYPASS Connect phone to PC and Turn ON your phone." but I can't turn on my phone. Also on Step 2 which is the SP Flash Tool thing, it says "Open SPFLASHTOOL choose in Download-Agent No_Auth.bin" but on my SP Flash Tool archive I can't find No_Auth.bin, is it somewhere from third-party or from the firmware itself? Currently I'm downloading the firmware and will try to flash it using SP Flash Tool to see if it works. Any help with this?
Best Regards,
Rev.

Follow this https://www.droidwin.com/unbrick-realme-6-6i-6s-sp-flash-tool/, of course, skip to download and flash the files that are for the other model, instead, replace from your phone's files.
The whole idea, is that you have to install the LibUSB drivers, so your device get recognized and can bypass the DA/SLAA restrictions for BROM mode, in MediaTek devices. When you can bypass it, then you can flash the proper firmware for your device, you don't need to power on your device for that, as your device is bricked...

Hi, sorry it took me so long to reply, the phone is finally fixed thanks to your guide! How can I make this thread or your post as a solution?

Iocean X7 Elite Bricked ('BROM ERROR : S_FT_ENABLE_DRAM_FAIL(4032))

I have just received my Iocean X7 Elite and was about to install a new rom. I had successfully rooted the device and then was trying to flash
the recovery with SP Flash Tool.
After the recovery flashed my phone refuses to turn on I believe its somehow bricked but have no idea how this could have happened. I did
format flash i only downloaded the recovery to the device.
In Device Manager when i plug the phone it it either shows up as 'DA USB VCOM Port' or 'MTK USB Port'.
When I try to use SP Tool to flash the stock Rom back onto the device I get an error saying 'BROM ERROR : S_FT_ENABLE_DRAM_FAIL(4032)'
I have no idea what to do next can someone help me.
I have tried what this thread suggests:
bump
same as u..but differ phone model.(N9589)
had a few upgrd...til the recent brick it.
Tried a few version of flash tool and still the same

Same problem here - tried to install stock firmware and got this error...
these are common problems when flashing MT65xx based phones,
ie : error 4008, 4xxx, 5xxx whatever those codes mean, no explanation after extensive search on google.
once I managed to flash this one phone successfully, but I don't know exactly what I did.
as long as I recall, I tried to delete the whole flashtool folders, re-extract them, let the phone cool down a bit
and oh, try to press volume up, or down button (varies on devices) while connecting to USB, once the flashing progress bar starts, release the button.
In the flashtool option, at the OPTIONS-->DA DOWNLOAD ALL-->, check WITHOUT BATTERY.
and in the option, DA DOWNLOAD ALL--> SPEED, check DO NOT SWITCH SPEED.
try flashing your phone without battery inserted, it works many times for me.
NOTE : BEWARE, flashing your MTK65xx based phone, sometimes this tool tried to REMOVE YOUR PHONE's IMEI information, so take caution !
I haven't managed how to prevent IMEI removal when flashing those phones, because I'm not a developer.
Hope this helps.

Thank you for your reply, but this doesn't help... ;(
Anyone?
I think I figured out that the error above means you are trying to flash an incorrect ROM. Make sure you are using the right one and also make sure you're using the latest version of sp flash tool.
Once I downloaded a later version of the flash tool it began installing the ROM but then a different error appeared.
So I formatted the nand with the sp flash tool.
Then I flashed the stock ROM again and it worked
Formatting it seemed to make the errors go away even though its advised not to do so.

Iocean X7 Youth
I don't have the same problem but i flashed the latest version of official rom for iOcean x7 Youth : 03 july 2013 : and wtf no more internal sdcard only the rom stockage. So i can't download anything, i can't use camera .
On the official website, I read that before flashing the 20 may 2013 rom one and the 03 July 2013 one, your baseband version have to be 23/04 or higher( you have to flash the 23/04 official rom first). This is only avalaible for the YOUTH version.
So tomorrow i will try what i said below to see if i have internal sd card again.
noob question::: since the iocean x7 young and turbo are the same phones...only different clock rates...will flashing the firmware for turbo on iocean x7 young work??assuming that the mtk6589T and mtk6589 are the same chipset only different clock rates??

Clearly: Wrong driver. I had also this error. SPflash tool did not readback. I did not flash anything! I fixed this by showing the nonpresent devices in devicemanagement (google for show nonpresent devices for explanation)
Go to com ports, and delete all mediatek drivers except preloader driver. Now start over. It can help if you choose the same usb port where you had success last time.
SP flash tool shows in the statusbar which driver it is using.

My x920 got bricked randomly. Version: e2001v21_v89_zlh_hd

Hello guys I got a x920 and was working good until it started doing something similar like Samsung Galaxy S3 Sudden Death.
The phone would randomly get a screen freeze, and the half bottom of the screen got distorted like green and pink lines, then slowly, the pixels were turning to black until the whole screen gets black, but the backlight would remain on.
I had to pull the battery out, and sometimes the phone would work again instantly, some other times, it wouldn't turn on, only after some time, and after a lot of battery pulls.
But last time I got this sudden death, the phone never came back.
I had the stock rom and only root.
My model version is: e2001v21_v89_zlh_hd
Most people with this phone have the e2001_v89_zlh_hd, and most roms on needrom.com are for e2001_v89_zlh_hd, there are a lot of roms for e2001v21_v89_zlh_hd though but I tried everything and I got DRAM Failed.
I use windows 8
SP flash tool v3.1304.0.119, v3.1308.0.125, v3.1316.0.150
And several other roms for both versions.
There is a solution from a French guy about the DRAM failed problem here, but I got the S5 rom downloaded as he stated, and can't get pass the first red bar on SP flash tool.
Do you have any idea what is going on with the 2 versions of the phone? People say that they read on chinese forum that v2.1 (e2001v21_v89_zlh_hd) has got different EMMC. So I guess roms from the e2001_v89_zlh_hd wont work.
I would like to know if you guys have any working rom for my e2001v21_v89_zlh_hd because I really need the phone at the moment. I must get it back to life.
ps (Is windows 8 suitable for flashing? I have installed mtk drviers normally through a weird process enabling manual driver installation through the advanced startup thingy on Windows 8, otherwise it wouldn't let me install the drivers.)

ok, there is no difference for using window 8 , xp, win 7, as long as u have installed the driver correctly.
as u said u can see the red bar, that mean yr driver was installed correctly.
all u need is the right preloader.bin
as i can understand from my past experiance, i think that the later batch of the phone, the manufacturer might use different DRAM or they might have changed the coding of the ram. that is why we see quite often there is complaint of DRAM fail when u try to flash the official rom for the phone. Not for newer model of the phone ( yr phone has two/three batches).
so may be u could ask the http://www.needrom.com/mobile/star-tengda-x920/ - smartdigi to create a preloader.bin from their phone for u , then u replace the preloader.bin in yr rom and flash it.
smartdigi is a team from Greece, and so am I, so yes, I just sent a message.
I hope I'll find a solution.

i had read tru the needrom wed regarding thier rom, i saw there is a instruction to pass tru the "DRAM fail."
had u tried that before.
they also had rom that match with yr version.
Yes, I downloaded the rom, and still got DRAM failed.
Is there any way to install smartdigi rom through sp flash tool and not sd card?
here's the link http://www.needrom.com/mobile/star-tengda-x920

ok, i just want to know if the procedure as they decribe will work, as i cannot test it, as i don.'t have the phone.
did u manage to get the preloder from them.
if u get the preloader from smartdigi , u stilll get the "DRAM fail" , then i think , may be their phone is an older batch,
for me, if u can read back from from the SP flash tool, (version 3.1316, (i justy learn that there is v3.1328 available)), then definitely u can flash yr phone with this preloader.bin
note
since u can't even go to recovery, then there is no way u can flash the rom with card flash rom from smartdigi, the only way to recover yr phone is tru cable flash rom that mean, u have to pass tru the "DRAM fail"
Well, I found the problem, the drivers installed are MTK USB Port, and not Preloader VCOM drivers.
I use windows 8 x64, I restarted with bypassing the signature thing.
The problem is, when I try to manually select the vcom driver, after the installation it shows up as MTK USB Port, and not as a vcom port.
Any solution?

no, it does not matter if it is preloader port or vcom port, actually they don,t make difference if u flash the rom.
that mean yr computer is talking to the phone correctly.
now the most important part is the "preloader.bin" file in yr rom must match the dram in yr phone.
that is why u hve to ask who has yr exactly same model of yr phone to create a preloader.bin.
or just try to download the preloader.bin as many as u can.
if u have a friend who has the phone same as as yours, then i can help to create from his phone, or u can create the preloader.bin from his phone
edit,
try to download the latest sp flas tool v3.1324 or v3.1328 ,flash the rom with it.
I tried several roms, with different preloader.bin files, non seems to work.
I tried with all sp flash tool versions, all 3.13904.0.119, 3.1308.0.125, 3.1316.0.150, 3.1328.0.183
Some versions of SP, are not showing up all the files gathered from the scatter file. Some other do.
Well, a smartdigi member, told me to use windows 7, because the mediatek drivers have gone as fas as windows 7 x64.

ya, u could try with win7.
for me i can flash with win8 also.
i use win 7 at home, win8 at office, no problem.
u could try with win7, i think most likely , u will get the same result.
i had brick my s7589, i unbrick it with the right preloader. after that i tried with the preloader.bin that was originally came with the rom.
this time , it can pass tru the "dram fail", get the purple color, then yellow, then finish with green color. then i try to swith on the phone, but, no response from the phoe. it was bricked again.
then i flash back with the right preloader.bin, the phone back to life again.
did u manage to get preloader.bin from smartdigi?
for me, it is the best solution to unbrick the phone. may be there is some other ways that i don't know

Well... installed windows 7 in another partition.
It was like I never did it, exactly the same result. Everything behaved the same.
I don't know... maybe I have crappy mtk drivers, or I'm doing something wrong while installing them.
Let me describe the steps, and if I'm somewhere wrong you can tell me.
Well, after a clean windows 7 install, I connect the phone to the pc (with or without battery,I think I tried both, didn't see something change) it gets to "other devices" as an "unknown device". right click to update driver software, select the folder with vcom drivers.
It gets recognized as a mtk usb port.
Try to flash like that, same results.
Then I go to update driver again, but this time I click "let me pick from a list of device drivers on my computer." I uncheck show compatible hardware, then I choose MTK Preloader USB VCOM Port.
the device now shows up to the device manager as "MTK Preloader USB VCOM Port".
Try to flash, everything is the same...
I read somewhere, that the normal installation of vcom drivers is kinda different, that it get's shown up as "MTK Preloader USB VCOM Port" right away, and I read that when you install the vcom driver correctly, it connect and disconnects the device every 3 seconds.
Well.. I didn't manage to get the preloader.bin yet, I'll ask for it, but why the official rom on needrom.com preloader.bin is not working with my phone? And why would smatdigi preloader.bin would work for me?
I tried roms that are for e2001v21_v89_zlh_hd but even their preloader wouldn't work for me.
first of all, stop playing with those preloaders. random flashing will brick your motherboard of your computer too, if you flash a wrong BIOS file. clear? okay. the DRAM error occurs if the Rom is mismatching the "signature" of your device. so, before trying to flash it, take another one, in this case, the right one. ( for example: my device (n9770) got few cameras, few board revisions, ddr or ddr2 Ram and so on, only one Rom or a mix of different files will work)so flashing a wrong firmware causes more "damage" or "errors". have you backed up your firmware before rooting?
you need to find a full backup of your device ( most likely a Rom directly from your vendor) including ALL needed partitions for flashtool. ROM's of new devices are hard to find, even for n9770 (mt6577) there are ROM versions from 06-2012 till now. so, if you got a "newer" device, you need to get the correct firmware and flashtool should flash without problems. also, your drivers are working perfectly, otherwise flashtool won't show the red bar wich is checking the device.you may need to check if the "second" driver is installed correctly, because the device will switch from preloader mode to "flash mode". maybe the driver for the preloader is installed correctly, but it can't switch to flash mode.

I bought it from focalprice, even if they send me any rom, it will be one of the officials found in needrom.com ... So I don't think they'll handle it.

How can I check that the second drivers is installed correctly?
just open your device manager and check, if the device gets recognized correctly. start a flash and check, if there are any devices gets loaded while trying to flash. if so, install the correct driver. there are some issues with that sometimes.
if this won't work, try using MTD tool. flasing through there should work always, but it got some issues with vcom drivers. you need to assign every vcom port to the mtk device. explaining of this is retty hard since english isn't my motherlanguage, so its best to check google or xda for that.
also, can you start your device into recovery, or is it really "dead"? no bootlogo, nothing?
No the device is hard bricked, no recovery at all. Not anything. :/
I can't use MtkDroidTool, it doesn't detect my device.
hmn, i would suggest its a hardware failure. never saw a device "dying" without flashing before.
btw: i meant SPMultiPortFlashDownloadProject tool, this is a more advanced variant of sp flash tool. just google for it and put a log in here, so i (we) can check whats the matter.

did u manage to get the preloader from smartdxxx............. ???????
it just takes 5 minutes (the most) to create the preloader from the phone.
take up the battery from the phone, run sp flash tool, connect the phone to computer, 5 sec, the rom_0 is read
put back battery, on the phone, connect the phone to computer, run mtk droik tool, 30 secs later, the preloader is created.

I just saw this post as I too have a Honor 7S
There is NO TWRP for our device.
The TWRP for the Honor 7A/7C/7X and Honor 7 doesn't work on our device and you got to pay 4 euros to unlock the bootloader before you can even flash TWRP (and there isn't one)
This Device is treble compatible but now I've found out there is zero development and no Devs Interested in it it's a complete and utter waste of time and has gone back into its box, never to be seen again.
hi there, I get this phone recently (because is old) and I created twrp for i,t so here it is, if you want some fun
you can flash it via flashtool on locked bootloader in to boot partition and after that you push twrp.img via adb to internal storage and flash it in to erecovery and recovery slot, and you are good to go

Hi I have a problem. I'm having brom issues in trying to flash it
Hi
I thinking you dont have "Authentication file" so you using "mtksecurebootdisabler",
so you need patch your drivers with libusb "patch".
Try this one, for me it works.
So open libusb that you install.
connect your honor7s to the pc with disconnected batery and hold volume down.
in patch option select your usb mtk device "idk how is called" and patch it
after patching reconnect phone and it will works.

and little hint
dont flash whole rom if the phone can boot becasue after clean flash "format+download"
you lost log and cust partition because the image files are not secureboot signed and your phone get in to bootloop
and also you lost imei codes so no cellular after that
If you do so
you can fix it in that recovery were I enabled option to format log partition
after you format log to ext4, your phone will boot but without huawei/honor bootanimation
you dont need to worry about cust partition, if you didnt format it it still boot but without bootanimation and you lost some of garbage apps that are in that partition (amazon etc...)
(twrp boots in russian language, idk for now how to change it to boot in english or slovak lanuage (because Im from slovakia) and also it have Lenovo Logo becasuse I use sources from Lenovo A5 that have same cpu)
I will make in future separated thread for this....
Thanks alot for this.. I don't know maybe I should try the disconnected battery. But from a yt link I saw
The link : Honor 7s Dua-Al000
I wonder how his worked
I'll have to know how to disconnect the battery thou. I'm a noob at this.

Sorry for the noob question but after patching with the battery disconnected. When I want to use spflash tools would I still use disconnect the battery to flash the recovery and co.

you can patch it or flash it without disconecting the battery
Here is how:
turn it off
Push and hold volume down
While holding volume down connect usb cable
But is recomended to disconect battery because the phone can boot up instead to go in flash mode.

Well he did with the battery and he add more steps that are not necessary for flashing, like scanning for COM port etc...
When I first try flash my 7s I download flashtool and didn't change any settings, I just load the rom and flash it.
So you must try to find your best way how to do and I will help you
And I wonder how he can flash the Log and Cust partition via flashtool, Maybe he have unlocked bootloader or something
Update: he have in the video description link for "lib usb" but didn't show it in video, or I'm just blind or something

At this point. Might just abandon it. Thanks for everything. Ran into laptop issue on my third trial lol.
Yeah I see, drivers issues, it happens to me too, but I install windows 7 and everything works... but I think is not worth it to format your laptop and install win7 only for this mediatek crap, where you can't unlock bootloader or anything because Huawei trying to protect customers and they believe that their android is best for they're phones

Honestly. I spend a whole night researching videos for the phone. Only to get that link I send. And after all that. It still didn't work. Lol. I have a Poco x3 pro. I wonder if snapdragon android 12 can be rooted. Probably going to try it next month or so.
Snapdragon is eazy for root.
I have Redmi note 11 and it was easy, now I running on Android 13 from stock android 11, if you will need some help with something, I'm here, and I think there is device forum so there is community for that device

I wondered if someone could try to help me? :)

Hello guys! I have a problem with one phone that i am trying to fix for someone and I feel sooo, sooo completely lost in all of this as I know almost nothing about this. The cell phone model that is in question is Alcatel One Touch Pop C3-4033x.
It seems to be using a Mediatek chipset and I was reading some of your advices here & there and tried using the program called SP FlashTools but it always resulted in error, in the end. It seems that something is wrong with this phones emmc flash memory. So, I tried transfering some files as a zip files to the SD-card and tried to apply update from it, but it said always: Installation aborted. And then, I have tried looking for a way to flash stock firmware of that specific Alcatel model on SD-card, but I just don't have any clue how to do it, if it is possible, even. Maybe I should just give up trying?
Oh, I almost forgot to write that the phone doesn't have the access to Android OS and USB debugging isn't turned on, because computer doesn't seem to list it and I don't know if there any button combinations that Alcatel uses for this model to get into that fastboot or adb mode, even though have installed mediatek drivers. It can only get into Android System Recovery 3e. That seems to be everything, I think, at least.
Oh guys, I am so, so, so sorry if I am bothering you with this. I just didn't know what or where else to ask this. Thank you sooo much!
Hi download those files:
Firmware:
https://www.mediafire.com/file/bpm4ibsbmr4q6nc/OT-4033X-Without_Mobilis_logo__BY_GSMSERVE.rar/file
SP Flash tool:
https://androidfilehost.com/?fid=11410963190603870440
Driver:
https://mega.nz/#!8VYkQCxD!fkhTrZwFFILDAglO1cR_8pIM4Cel52brZ7RB6QZoc6o
Once you downloaded all right driver open SP flash tool and add Scatter file
MT6572_Android_scatter.txt
Click on Download , connect your phone without battery and see if the process is going on if not try again with battery inside.
If you end up with error do the same thing but now first do Format then after is Finish do Download. Good luck ...
It still displays error :/

I have tried to do everything like you have said, but it still displays error when i press the Download button, and it displays that error after some seconds pass and also the same happens hen i try to use the Format function. This is the error it displays when i tried with the download button: BROM ERROR: S_DA_SDMMC_WRITE_FAILED (3149)
And this is the same error it displayed when i tried using the Format function: S_DA_SDMMC_WRITE_FAILED (3149)
i am so, so sorry for bothering with this.

Issue with Alcatel mobile upgrade S tool

Hi everyone. As I said on a former post, I have an Alcatel 1t 7 tablet; I need its stock recovery image, but even stock firmware is getting impossible to find. I mean, apparently there are firmware for that reference of tablet, but what happens, is that there are several models that share the same physical appearance, but have different hardware, so, they have different firmware, and by that reason, their firmware don't work for my tablet. Anyway...
The fact is, looking that its original firmware is not available on the internet, at least publicly; I'm trying to reflash my tablet by using alcatel's tool called "Alcatel Mobile Upgrade", a tool that I don't guess, would be unknown for many of you. So as I said, I'm trying to reflash it with it (and in the process, restore stock recovery, I hope). So I installed MTK drivers, installed the version recommended for this tablet, followed program's instructions, but when I reach step 2 of 4, the program warns me saying this: "Read terminal information failed. Unplug device, remove the device battery and plug it again - Repeat step 2 and try again".
The issue is, that its battery is internal, not removable; even, is soldered to the board. And I must add, that at first, when I bought this tablet and began to "experiment" with it, I was using SP flash tool, and it was giving me almost the same warning that Alcatel mobile upgrade, but later I discovered what that was a fail of the used sp flash tool version. On a webpage, someone recommended a specific version of sp flash tool to fix that issue; I mean, that I could download firmware to the device without having to "unplug battery"; and It worked.
So first ¿How can upgrade my tablet by using that program?¿What am I doing wrong?¿ Which device must appear under device manager, to it can work?¿mtk usb port, Mediatek DA usb VCOM, Android preloader, or which one? And second, ¿Could be this problem, due to alcatel's mobile upgrade version?
let battery drain to make sure device is powered off. you only have preloader mode for a second - within this time pick up in device manager and install preloader drivers.
if drivers installed correctly, first start flashing, then connect phone. flash tool will keep device in preloader mode for the flashing time period

Thank you for replying. Definitely using Alcatel mobile upgrade is not an option, at least to me. I mean, I couldn't make it work in any way. "Fortunately", after an exhaustive search, I could find a post on internet, that recommended for a similar issue, to use Sugar MTK; the publisher shared this program and its credentials, for can use it . So I downloaded and used it, and I could restore my original stock. Now my issue is to port it to TWRP, but now I'm gonna to write a new post about it.
link me to the sugarmtk
