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.

Apparently sometimes it's not the best idea to use the flashing software that the manufacturer of your phone released.
I have a Wiko Lenny(technically a MediaTek MT6572) that has(or had - now it's dead) the habit of simply rebooting into a bootloop every few months. Fixing that was simple; just start SP Flash Tool, format everything then flash the stock ROM back. Last time I did that was around 4 months ago, and since then I have upgraded to Windows 10, and as such, lost the tools I had installed.
Yesterday it went into a bootloop again. I didn't remember exactly what tools I used, so I assumed they were the tools that Wiko supplied a while back with the V10 ROM. Well, they weren't. I still thought I'd give them a try. I mean, it's from the manufacturer's site, so they must work even better that the ones I was using.
I was wrong. The tool flashed the ROM "successfully", but the only thing it actually succeeded to do is corrupt the preloader. For those who don't know, corrupting the preloader basically means the phone won't even power on(not boot, actually power on), won't charge, and the PC won't detect anything if you connect the phone. Practically, it's the hardest brick a phone can get.
The fastest way to fix that is by either using a JTAG connection to flash everything manually, or by entering something called the Mediatek META mode(don't quote me on this one, though - I never heard of it before). JTAG - well I don't have the tools or expertise necessary to do that(although I'd love to learn how to do it - if anyone can point me to a well-written guide or two about that, please do!), and I simply can't get the phone to enter the META mode.
Is JTAG the only way to do it? Is META mode just a myth? Is there a way to save my phone, or should I just say "RIP" and buy a new one(I have the money for a Samsung Galaxy A3, the new one, but I was planning to buy a new computer with that money - is it worth it?)?
TL;DR (It's not that long but anyway...):
I have a Wiko Lenny(Mediatek MT6572) with a corrupted preloader after I flashed it with Wiko's tool. Can I repair it or should I just buy a new phone?

Come on people, let's fix this little guy.
EDIT: Please, just tell me what your ideas are... A tip, a crazy idea, some details about MTK devices that could help, anything is appreciated.

Looks like I'm getting the 10 posts just by begging people to say something... :crying:
I have an MTK phone and its always going wrong and not booting/turning on because I mess with it and break it
I'm sure I flash the backup I made in mtktools with spflash, and plug the phone in with no battery attached, I also have to use windows 7 on a dual boot as windows 10 never played ball properly. You also need the mtk VCOM driver installed, not just adb and normal drivers. If you have all these, and have tried them, then that is the end of my knowledge sadly. Only other thing is going to needrom and seeing if they have a full rom/backup with partition tables/preloader etc.
Also, had to try a few versions of sptools as certain versions didnt work, forget which one I have and which didnt work. And also had to use a samsung USB lead as the stock one didnt work, or the other way round. I just remember it was a ball-ache but did eventually work. Am not on that pc so cant be more helpful, sorry....

Repair your own device
Soft Brick: Soft brick is the state of android device which occur due to some software problems like boot loops or phone freezing at some point during boot. This only occurs if some software problem occurred in the device mainly during OS upgrade or ROM flashing. If your device is in such state then you are luck there are 99% chances that you can recover your beloved device without needing any professional help or spending hundred of dollars.
Hard Brick Hard brick is the state of android device that occurs when your device won’t boot at all i.e. no boot loop,no recovery and also not charging. This occurs due to trying to flashed firmwere not made for your device or flashed incorrectly. This is more difficult to resolve and often require professional help
in MTK Android there is many Partitions in your phone. like Preloader, Recovery, Bootimg etc….. if somehow Preloader get Corrupted then you phone will not able to DETECT WITH PC !!! in other words you will have phone with BOOT DEAD.
How Preloader get corrupted ?
There could be few reasons but main reason could be that someone or you Flash your complete phone (include Preloader) with wrong files or with wrong ver. Also there could be reason someone Delete Preloader or you Deleted.
How could i know my phone have preloader dead ?
Preloader can be dead if some one Flash it wrong and after flash your mobile will not detect with pc any more. for confirm
1.sp flash tools does not detect your phone anymore and also the computer does not as there is a pop sound when usb is connected to device
2.open device manager
take battery out from phone
insert usb
insert battery
and check is computer detecting any device
If it’s not detect then you have phone which Preloader is dead AKA Boot Dead
How can i repair it ?
requirement
1.screwdriver (by which you can open the screw from handset)
2.bricked device
3.a usb cable
4.a copper wire( for sold test points)
5.a pc with sp flash tool,mtk drivers and stock firmwere for your mobile
now you have to disassemble your phone and take pcb out. check there should be some Golden points. check these points there should be written on them Rx,Tx,GND,Vcc,Vcharge etc… check there should be written “COLO” or “KOLO” or“KCOLO” you have to Sold that point with GND After Sold Attach usb now your phone will detect with USB !! and now ready to Flash.
In some phones “COLO” or “KOLO” or “KCOLO” not written for those type of phones you have to test all points one by one Short Golden point with GND and attach usb cable which point short with gnd can able to detect your phone by pc isForce Preloader Mode Test Point !! Keep in mind Don’t Short Vcc,Vcharge or any other pin which have 4.x Volts also i had tested “Colo” or “Kolo” or “KCOLO” don’t have any kind of volts.

Hi I also have the same problem - when I flashed the stock rom of my LG K7 X-210 (MT6580__lge__LG-X210__m13g__5.1__ALPS.L1.MP6.V2.19_ARIMA6580.WE.L_P42) with the SP Flash tool when I was in a bootloop, I accidentally forgot to uncheck the preloader option. I flashed it to my phone and from that point onwards it didn't want to start up any more, nor would it react if I tried charging it. So conclusion: the preloader is corrupt...
However, I read online that MTK devices (mine is MT6580) have a 'meta' mode which allows your device to still connect to SP Flash tool even if it is hardbricked (in my case by pressing the volume up button, and then simultaneously plugging it in the computer). It is then recognized as MTK Com port something in device manager.
Luckily I have the same phone (but it's not mine) and I was wondering if it was possible to make a full rom dump from that device and restore it on mine? (a method that is safe for the other device as well)
i have a proble on my new phone since i flash preloader my touch is not working anymore, any solutions ?

Hello, is it too late to write?
My Chinese Android car head unit is stuck in a bootloop (the home screen shows but the unit reboots after a few seconds). I got a firmware zip file from the manufacturer (the zip contains files like scatter.txt, ramdisk2.img, boot.img and so on). However, I'm unable how to find out how on earth I can install this firmware and get out of my bootloop.
I have no access to Android itself (the system reboots too soon). There are no physical buttons to activate recovery mode. When I use a USB keyboard I can get into recovery by pressing ALT GR and PRT SCR but after a reset "no command" shows up and I'm stuck again...
Any help please?
Flashing instructions
[Apologies for the lengthy reply, I have to assume that you have no experience in flashing MTK SoC]
Sorry to hear that! I am also contemplating t buy a Chinese Android headunit with GPS but I am still contemplating. Reason being which model to buy? I am an avid Lenovo devices fan because in my part of the world models from Lenovo uses a lot of MTK SoC. (Any other other brand I buy is also a must to be on MTK SoC)
Ok! Now based on your short description I saw "scatter.txt" file mentioned so it is definitely an MTK devices, 100%.. When you boot loop you definitely will not be able to access any function, more so with a head unit that dont provide hardware buttons. I can only help you understand the method to reflash the firmware on MTK devices the rest you have to figure it out yourself.
The USB port is your key here. If the manufacturer did not provide you with USB "IN" (female) port which is not normal and only provide you with USB connectors you will have to decode/or just connect the wiring from the connectors to a USB female Port (which what China manufacturers do at the back of the head unit). There are also head units that provide ready to use USB port on the facia.
Whatever it is I cant tell you which port to use. This where you will have to experiment yourself.
Download MTK flashing tool "SP Flashtool" (find the ones that is suitable upto MTK device 6592 because it should be back ward compatible with older devices) The Chinese dont use the latest MTK SoC for their head units, that is only reserved for the high end heads.
Read up on how to install SP Flashtool on your PC and other accompanying Drivers you have to install, (if you only have a Mac go borrow somebodys Win7 or Win10 PC) there are no Mac SPFlashtool.
Once you have install according to SPFlashtool instructions you read. (It has to follow a certain sequence) e.g "1- ADB Driver" so on and so forth because if you dont follow the sequence it might fail to start the flashing operation. (You will not know it but I am pretty damn sure you will be cussing me).
First read up on how to install ADB driver for MTK devices correctly. Confident? Now try connecting your device to the PC experimenting to identify the correct USB port to use. If the ADB is installed correctly and you got the right USB from the device connected your PC wil give an audible sound( it should unconnected to condition evreytime you test). OK good connection! Only then try installing SP Flash tool and try a dry running the SPFT. If your installation is correct there should be either color changes to the SPFT window because it doesnt detect any devices.
You are good to go! Your MTK Android device should be in the "OFF" condition (after every shutdown there are still some operation running in the background,so it is a good practice to wait at least 5 seconds for it to be 100% OFF.) Run the SPFT fully loaded with the firmware dislayed in the SPFT window. Then initiate "Download" (make sure all indicators is at "download only" do not change this option or you are gonna have a really dead duck.) At this point the SPFT is active and waiting for you to attach the device to PC (before running make sure the PC and device is not connected yet!). If everything is per instructed ADB, USB Cables/Ports, SPFlashTool (download only) you will see color lines in the SPFT Window, wait till the end of process it will display notificatio. If the firmware is correct and you have attached and 12V DC source to the device it should boot up as fresh as new.(provided that the supplier gave you the correct firmware).
A word of advise these cheap head units normally bluff their actual Android version e.g actual KitKat advertised and displayed as Marshmallow. Best of luck!
The zip file attached are screenshots of the flashing process.
Thanks for your very elaborate information, but it won't work. The ZIP I got is an OTA zip file. The scatter.txt inside those zips isn't compatible with the SP Flash Tool.

Doesnt the seller provide you with the original firmware? He only gave you an OTA?? Oh $#it! The OTA file is small probably a few Mb? The full firmware in your case should be around 800Mb upwards. You are right an OTA cannot use SPFT it can only be flash through the original recovery (not custom recovery). If its a popular Chinese model ML-CK1018 or Joying brand ( I assume you bought a Joying? Thats the only brand that release an OTA not long ago) There is remote possibility of getting the firmware.Anyway just give your brand and model number. I will try to look on Russian or Chinese site but no promises! Will try.
But I am pretty sure it is an MTK SoC since you can unzipped and it shows "scatter.txt" file. Most other SoC arent normally in zip format and have scatter file.

The OTA ZIP file is about 900MB.
It's a NAVITOPIA 9 inch 4G LTE WIFI Head Unit with Android 6.0 2G + 32G.
I'm in the same boat, have a plastic bookend at the moment, will not connect to the PC because flashed and formatted my device with the update firmware!!!
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.
