Use the Read Back tab. For starting address and length, you have to open the scatter.txt file. Find the partition you wish to read back. The starting hex address is the linear start address in the scatter file. The hex length is shown in the scatter file.

Do NOT power on the device. You are supposed to keep it turned off. So, click download and then connect your powered off device. Do not touch the power button! If the download does not start, keep the VOLUME UP button depressed while you are connecting the USB cable to the phone.

Your message is very confusing! First you said that you changed the LCD and the digitizer on your phone and immediately after you changed the hardware, it did not work. Well, obviously, you did not properly change the LCD and digitizer. Are you sure they are the correct components for your phone? If they were correct, they should work, no. But to solve this problem, you changed the uboot.bin in the firmware of the phone? How did you do that...did you flash a different uboot.bin? Why would you do that? It is not a "driver". You can't just go changing boot elements...you have to use the stock uboot for your phone!

Finally, if you had mistakenly flashed a Jelly Bean stock ROM when your phone was running KitKat, you will see all white or gray/white bars on your screen, or other strange effects on your previously soft-bricked phone, which sounds like it's now hard bricked after you flashed a different uboot.

You have to use the scatter.txt for your phone or another phone that is EXACTLY the same as your make and model of phone. Usually, you can download a stock ROM for your phone and it will come with the scatter.txt file included.

---------- Post added at 01:10 PM ---------- Previous post was at 01:02 PM ----------

You cannot use MTK Droid Tools to get the scatter file now that your device is bricked! MTK Droid only works with a functioning booted device my friend. You have to find and download the ROM from the internet. The scatter file comes with the download. Then flash the downloaded ROM onto the tablet using SP Flash.

Alright. Before I get into another mess: I have this Huawei G730-U251 that I've recently updated with a very official Huawei update. Big mistake. It only brought something I call issues and new restrictions; now I'm not able to use Link2SD and Adaway (main reasons why I root) because some parts of the system can't be mounted rw. Process to achieve rw are getting way complicated so I decided to just install stock 'unupdated' ROM again via 'dload'. Process fails, so next step is to try SP flash tool. Question is, can I 'downgrade' ROM even by means of using official stock Huawei 'UPDATE.APP'?... it's the same 4.2.2, update just changed something but not for root good.

[Upgrading, Modifying and Unlocking] CVAngelo:
That's not a scatter file. You can't create a scatter.txt file from SP Flash Tool! You have to download the correct scatter.txt for you phone. Or use MTK Droid Tool to create the scatter for your phone.

That's a dump/read back of all or part of your ROM. How exactly did you get this file. Tell us the steps you used, because you cannot use SPF unless you FIRST have a scatter.txt. Which scatter.txt did you use???

And what exactly are you trying to do?

Is it possible that we might need to restore IMEI after flashing custom ROM? There is mention of this even as requirement and part of some other SP flash tool tutorial I've seen here...

http://androidmtk.com/flash-stock-rom-using-smart-phone-flash-tool
[Upgrading, Modifying and Unlocking] CVAngelo:
Yes, use SP Flash Tool to flash the stock ROM for your phone if your phone uses the MTK chipset.

---------- Post added at 11:55 PM ---------- Previous post was at 11:53 PM ----------

Highly unlikely, but yes, you MAY have to REPAIR your IMEI after flashing a custom ROM. There are tools out there that you can use to effect such repairs. For example, download Chamelephon from the Play Store. IMEI repair is pretty quick and easy. Your phone has to be rooted to access nvram where IMEI is stored.

This "preloader" file... why it isn't mandatory to select it on the list of images to flash? Is this not actually part of a stock ROM?

---------- Post added at 01:07 PM ---------- Previous post was at 12:53 PM ----------

Hi CVAngelo. We meet again. I was actually concerned about flashing original but non-stock ROM on a bricked Huawei G730 and then having to restore IMEI and whatever important that might disappear after flash, since I had no backup for that. Well, thankfully, it didn't happened. But I've made a new question regarding "preload" file installation... do you have an explanation for that? I did not flashed "preload", btw...
[Upgrading, Modifying and Unlocking] CVAngelo:
The preloader is certainly part of the stock ROM, but it is usually not flashed because there is typically no reason why the preloader would have been damaged. It is never the reason for a bootloop. If the preloader was previously wiped or incorrectly flashed, you would not be able to even connect the phone to the PC to flash it. This is why you should never risk flashing the preloader. And on some brands (like Alcatel), even if your flash the preloader with the correct file, it may brick the phone anyway. Lol.

So play it safe...don't flash the preloader as there's hardly ever a good reason to do so. Note: there are some situations where you are flashing the preloader in the correct context...for example, if you are doing a direct memory write of a full ROM dump. This is safe (less risky than flashing a single file to the preloader partition).

When you sue "DOWNLOAD ONLY" mode "PMT changed" means that the partition table of the device and of the ROM are different.

[Upgrading, Modifying and Unlocking] CVAngelo:
I don't think it will help, but you probably should not check the DA DL Checksum box as you did in step #3.

Since you cannot remove the battery before you connect the tablet to the computer, you should try to hold down the volume down button at the time you are connecting the USB cable to the tablet (try volume up as well and try also with the power button + volume up/down).

It seems that your tablet is not picking up the Vcom driver. Are you sure that you've installed the Vcom driver? Otherwise, this may be a hard brick if it still keeps coming up with error 4032.

The only way to solve a hard brick where the Vcom preloader driver is not recognized is to jumper the motherboard to force the preloader to activate when you connect to computer. You would need to take it to a pro to have this done. (If you got the capacity and tools, follow this guide https://youtu.be/_6cceA0RGHg)

I have a Micromax Canvas 4 device. Its a MT6589 based device. Please see the device details on the below link

http://www.gsmarena.com/micromax_canvas_4_a210-5590.php

I had flashed a Custom ROM on this device from one of the posts on xda developers. Then trying to make further modifications, i was getting the below errors in recovery:

can't mount /cache/recovery/log

and it refused to flash anymore ROM's.Left with no other option, i thought of flashing back the stock ROM and then rooting agn to flash a custom rom.

However, even the stock ROM didn't flash, i was getting an error

BROM ERROR : S_DA_SDMMC_WRITE_FAILED (3149)

I googled a bit and some forums suggested to format flash tp resolve this error. I did that and that worked and got a green circle with Format Ok.

Again, i tried flashing the stock ROM and now got a new error in SP Tools:

BROM ERROR: S_DL_PMT_ERR_NO_SPACE (5069)

I am stuck at this point and not able to flash the stock ROM. After loading the scatter file, only flashing of Preloader works. Remaining all is stuck.

Running a memory test on SP tools gives an error that

NAND FLASH WAS NOT DETECTED

Tried using SP_Flash_Tool_v5.1352.01 & SP_Flash_Tool_v3.1312.0.139

Please help me out. Googled all around but cant find any solution :crying::crying::crying:
[Upgrading, Modifying and Unlocking] CVAngelo:
First of all, you should NEVER flash the preloader! Why are you doing that? Which forum advised you to do that? You'll muck up the phone!

Second, let me guess what may have happened? The custom ROM you flashed moved you up to a higher version of Android than the original stock? For example, you went from KitKat to Lollipop? Now you're trying to flash back down to stock KitKat? If that was the case, you may not be able to go back down a level. You may have to flash stock or custom ROM at the same level or higher.

However, if you flashed the preloader, you may have mucked up the phone. On your computer, if you go to device manager, when you connect the phone to flash it, does your phone show up as MTK USB VCOM Preloader?
[Upgrading, Modifying and Unlocking] satsmagic:
yes i can see MediaTek PreLoader USB VCOM Port (COM9) for a second and then it changes to MTK USB Port (COM8),

that makes me think its still alive can be revived
[Upgrading, Modifying and Unlocking] CVAngelo:
Yes, it's still alive. Don't flash the preloader again though.

But you didn't respond to the other part of my question. Did you initially flash a custom ROM with a higher version of Android than your original stock ROM?
[Upgrading, Modifying and Unlocking] satsmagic:
[MENTION=6532230]CVAngelo[/MENTION] Yes thts ryt, the custom rom was on KK4.4.2 while the stock rom is on JB 4.2.1. There's no KK Stock rom released for this device by the manufacturer.

But I have earlier done this several times, flashing a kk custom rom and thn reverting back to JB stock rom without any issues, as I mentioned, the recovery actually broke after flashing the kk custom rom and thn I faced prblms in flashng the stk rom back.

Hello guys !

I've got some problems using SP Flashtool... I have the Elephone P9000, and I wanted to install TWRP, a custom ROM, things like that... But I always have the same errors, and I never find anything about these on the Internet. When I try to do a Firmware Upgrade, the red bar stop at 100%, it's not moving for 3 minutes approximatly, and it say everytime

protect1 : failed to get PMT info

So I tried to do it with Download Only, and I got an another error, but always the same :

Just to install TWRP you should use DOWNLOAD ONLY mod in Flashtool (not FIRMWARE UPGRADE).

Please check the right installation of USB preloader driver.
[Upgrading, Modifying and Unlocking] CVAngelo:
Sounds like you do not have the correct drivers installed for your device, or they are outdated. Reinstall the drivers for your phone, then restart the computer.

Another way to install a custom recovery on your phone is as follows: root your phone and install Busy Box X from the Playstore. Then install Flashify or Rashr from the Playstore. Use Flashify or Rashr to flash the custom recovery...you just need to have the recovery.img somewhere on the internal or external SD card (BUT BACKUP THE STOCK RECOVERY FIRST!)

Every MTKs is unique & as i've said it many times, i don't reply is to force you guys to google & read but still you guys just don't read... :rolleyes:

Below are some of the discoveries shared by users... :good:

Most importantly, you must have the exact same Factory ROM for your device

Try every SP Flash Tool version, Eg. Yours is the old MT6589 then try all Version 3.xx.xxx, Ver 5 just won't work !

Download separately, select only Preloader, download it then only download remaining

Some MTK requires battery while downloading, some require battery to be taken out then only it'll work

Try using different USB cable, different PC & even different Operating System

Last but not least, read all the google result, the Russian shared plenty of infos, use google translate.

Well thanks for responding and thanks for helping me google out there. But i have been trying all this over a month now.

[Upgrading, Modifying and Unlocking] yuweng:
You are not googling with the correct keyword, some MTK required totally different procedures like holding volume button while downloading, try this, its specifically for your device & ask your question at those threads, i don't own a Canvas 4 so i donno the correct way to unbrick it... :cowboy:
[Upgrading, Modifying and Unlocking] CVAngelo:
Well apparently, only the folks named above can help you. But I will suggest the following: use the latest version of SPFT but do not use Download tab to flash the images. Instead, use the direct memory write feature. It is found in a hidden/secret tab on SPFT. It is the best way to get around some of the error messages in SPFT (like PMT changed for the ROM, not enough space, etc). Be careful using this feature because it allows you to flash anything, to anywhere in your phone thus potentially breaking your phone if you flash the wrong thing to the wrong place including the protected areas of memory.

To open this tab, hit Control-Alt-V, then in the drop down menu select Window>Write Memory. You will now see a new Tab called Write Memory. To use that tab, the preloader.bin must be checked on the Download tab. On the Write Memory tab, you indicate the image you wish to flash and the starting linear address where it is to be flashed (you get this address for each image by reading it from inside the scatter.txt file). You can flash each image file in the ROM folder one by one. You do not need to flash the Preloader partition....in fact you should always AVOID flashing the preloader (because if you make a mistake you will hard-brick your phone).

Finally, when you use this Write Memory tab to flash, you must do so starting WITH BATTERY IN. It is a different flashing process than the Download tab where in most phones, you flash starting with battery out.

PS: If you perform a memory test and it says NAND memory not found, it is because your phone uses EMMC memory.
