Hello i got myself a soft-brick on mine Coolpad 7320. And i would un-brick it with no problem, only - i got no backup done i SP Flash Tools, and so far iv read its the only backup that can restore my phone from the dead
So mine question is
- Can i restore a soft-brick (phone responds to SP Flash Tool) Noth having a Backup done in SP Flash Tool ?
- IF no, can some of u folks do a backup of a clean install of any ROM on Coolpad 7320 ?
- Myby i can use a Scatter file (got one to Coolpad 7320) to Flash in SP flash Tool any ROM's from other devices ? (done so with Jayui G$S and fails)
I have tried to:
- Flash CWM backup with SP Tools (but it got no preloader and the Android extension is wrong)
- I got myslew a scatter file from 7320, and i tried to fill the files need for SP Flashing from other roms with similar prcessor (like Jayiu G4S) but fail
I will be very gratefull for help !
PS attaching mine scatter file from 7320 - myby it will help
update
I did read some more tutorials - as said i need:
Backup of the ROM done with SP Flash Tool - if anyone could send me this - i would call him King !!

Hi.
My 9300+ (chinese mtk6577) is dead... I have to updated wrong firmware and my phone will don't turn ON again, when I use the SP Flash Tool appears the message: "Firmware Upgrade could not be executed without PMT. Please "Download" ONLY first to create PMT on the target!
My internal partition is corrupted and i can't create PMT because my phone don't Turn On, but my USB is recognized by windows.
Please Help Me.

I know this is an old post, but this may help someone. (would have me a month ago)
Hopefully if your USB is seen in Windows you can convince SP Flash Tool to spew/download/write data to your phone while it's in Meta Mode.
I believe the PMT block is created by SP Flash Tool dynamically from scatter file. It's comparing the scatter file with what is sitting at the PMT address on the flash. If these two mismatch, you get the error you mentioned. If you want to force a new PMT that matches your scatter file's layout, you have to do a "Format" in SP Flash Tool. This will get you back to a PMT on flash that matches your scatter file, then SP Flash Tool will be happy and allow you to use Download (write to flash).
What is a PMT? A partition table that holds the addresses to all the other partitions.

PMT Corrupted & Format-all done
I faced the same error.......my PMT got corrupted (possibly due to an earlier attempt to re-size (system / data) partition using Swiftbootloader)...... & un-fortunately, I clicked on Format in SP Flash Tool as well.
Now all is gone.... phone doesn't switch on.........
Please guide...... to bring the bricked handset (Spice Mi-350n) to life again. I have backups..... but that relate to different scatter file (PMT) perhaps........ do I need to search & learn webos & acmeinstaller kind of things now?

Hi spandrd,
did u manage to resolve this problem. I am also facing this problem after attempting to re-size the partition using meteos mtk6589 rom edit apk .... Although my phone is still working properly without any issue, i am unable to root or install CWM by any means (tried mtk mobileuncle tools, tried spflash tool) but not working. Can you guide me how to root and install cwm as i am unable to revert to my old backup w/o cwm.

The best way to restore your phone was already answered in the previous post, that is to FORMAT your device and subsequently flash the official firmware.

Hi iZLeeP
Thanks for the quick reply. I dont have any official rom. The only backup i have is using the CWM backup of the official rom before applying a custom LG rom. If it is possible, how can i utilize the CWM backup of the official rom to revert back please ? I can see boot.img and recovery.img files in cwm backup; can i utilize them somehow to revert back ? Please help. Thanks.

Let me remind people, the first order of business must be to have a full firmware backup from the phone manufacturer or thru MTK Droid Root & Tools. Reading that you tried to resize your system & data partition, your cwm backup should not be affected by it. Try restoring to default the partition sizes using the app/script you used to resize. It should have that function. Then flash custom recovery and root and see if it works.
phone booting to main-screen or not?
hi HNaseer....
As replied by @syserr & @iZLeeP .............you can try to "Format-All / Format-All except bootloader" type of thing PROVIDED THAT YOU HAVE COMPLETE BACKUP OF RELEVANT PARTITIONS (till Cache and / or till FAT partition length) using SP Flash Tool........ & MTK Droid Tool......... PLUS, YOU WILL NEED IMEI BACKUP (IMEI No.) in such case if you want to restore.
SP Flash Tool needs Scatter File......... (obtainable thru MTK Droid Tool) & can help in backup of various partitions even if phone not turning on. BUT IMEI backup would be good........ IF YOU ARE ABLE TO BOOT / reach main screen after boot animation.
Rest of the details can be first read / understood from my MT6589 chipset type handset link from @Atrvscet : http://forum.xda-developers.com/showthread.php?t=2514419
Or, better search exact thread on xda / elsewhere to get stock / custom rom & flashing etc.
Lastly, if you are able to boot in recovery, best thing should be to flash / force flash original cwm backup from recovery.

HNaseer.... I agree with everything spandrd just said. I'd like to stress though, getting a backup of your NVRAM partition is much better than having MTKDT copy your /data/nvram. So if you have a choice, backup the NVRAM partition with SPFT or if MTKDT has that option use it. (I've rarely used MTKDT as I found aspects confusing)
Incredible.
Thank you so much. HAd almost given up hope...

Not sure what you are expecting to do with a FORMAT. If you had a good backup of your NVRAM partition, then what you would need is a SCATTER file and ROM files, you could FORMAT then DOWNLOAD the ROM files and your NVRAM file to your device with SPFT. But since you don't have your NVRAM partition, you don't have an easy path. FYI, I don't know new devices... there could be more complication than MT6577/75.

Try google, or search xda, or needrom.com...
This may or may not help you. If I were you I would use SPFT right now to try to backup your NVRAM partition if it's not too late. Your FORMAT may have wiped the NVRAM partition already. If it has wiped it, your only good path is to find someone willing to give you their NVRAM partition. Then somehow insert your own IMEI and WIFI MAC in and pray.

Hello Guys
still waiting for help please
Blu Studio Energy 2 -Backup file- firmware Please
So. I deceided to join this forum in order to ask for some help from all those people I saw while searching the net.
I have to admit I am quite a noob with mobile systems, although I have gone way too far the last 3 days!
Here is the problem: I have an mt6575 processor phone in which want to add Greek Language settings. I have downloaded a folder form the manufacture's site, but it didn't contain any instructions. Just some .bin files (ALICE.BIN VIVA.bin, SANSTAR50_6464_11B_BOOTLOADER_V005_MT6250_MAUI_11B_W11_32_SP_V1.bin and ZIMAGE_ER.bin)and a scatter file that can not be read by flash tool (scatSANSTAR50_6464_11B.txt).
After a lot of reading around here and a lot of other forums and sites I realised that in order to do anything, I had to root my phone. I wasn't able to do it through superclick or mtk droid tools so I followed the instructions I found here:
http://forum.xda-developers.com/showthread.php?t=2160490&styleid=18
However, I am stuck on the final step.. I can't seem to get my phone on cwm mode... In fact I am not sure I know what exactly this is. I manage to open my phone on the android recovery utility but I am not able to make any choice. Everytime I press some of the menu's choises an android robot with an exclamation mark fills the screen and nothing happens...
Anyway..even if I manage to finalize the rooting process.. I still don't know what to do with the files I have... should I use them somehow on flash tool?
By the way.. The files come with a tool called Multiport Download Flash Tool which looks like Sp flash tool but has too many port options.
I'd be glad if someone helped me with this!
Thank you in advance,
Irene
1. Dump your stock recovery image then make a cwm or twrp (preferably twrp) from yueweng's thread for mediatek devices via old cwm or twrp port tool
2. Flash it via sp flash tool (download MTK 6575 scatter from internet)
3. Then reboot into recovery and if in twrp then reboot and it will ask you to root it or not
Or
If in cwm then download supersu Flash zip file and flash it
You have root access now
Press thanks if helped
Hey all.
Easy question I hope! I've been following the guide to unbrick MTK devices, and have managed to get an original factory ROM to flash to the phone, green tick in SP Flash Tools. However, the phone still won't power on at all, save for the light if plugged into usb.
The ROM I've been using is an original factory rom named "ONE-TOUCH-4015X_POP_C1_FULL_STOCK_BACKUP" which is readily available online. I'm not sure what I did to brick it in the first place, but it was within SP flashtool. I May have formatted accidentally.
If someone coudl help I'll try to provide all logs or files requested but please tell me where these could be found as I'm not that good with flash tool.
To confirm the phone won't boot into any mode, recovery is dead, fastboot is dead....
same problem hope somone help us
also share ur backup please

no work this version. yes 4015 but no 4015x
Sorry I should have put my phone is a 4015X not 4015. The application does say 4015 which I selected and all went well.
my 4015x no update, it not load, only work flash mode connected to pc and no work mobile upgrade.
4015X Partitions
the 4015x has a different set of partitions to the older (dual sim) 4015
i have a modded rom (kitkat), a modded stock recovery (as stock is also wrong, wont mount data) and a modded cwmrecovery.
i will be posting these soon
i will create a new post for the 4015x version
and will also be asking for other versions of the 4015 users to post me there partition trees and i will repack some recoverys and some roms for you all
note: there are 6 versions that i have seen and they may all have diff tables
hope these will help the pop c1 community

Hello!
This thread is quite old but near my case.
I have an Alcatel Pop C1 4015X (cpu MTK6572M) that can't start at all (only the power LED is ON).
I have a backup of this device made with "SP Flash Tool V5.1532.00" but I've error "not enough space" when
I try to restore it.
Same error when I try to restore just one file.
For example, I've tried to restore only the "Stock Recovery" you give above.
I do this:
- I start Flash_Tool v5.1532.00
- I open scatter file from my backup done with the same tool
- I unselect all pieces of the backup except "Recovery" and I browse to the "Stock Recovery" file I've dl
from this thread.
I've got this error : "not enough storage space (1011)"
What could be the problem ?
I makes me totally crazy !
By advance, thanks for your help.

Freeman.

What i did was i used SPFT to flash a backup i found online. Can't post links, just google "ot 4015X Original SPFT ROM", what i used was the algerian rom. Then i flashed the EE stock rom. My own backup didn't flash back correctly either, that's why i used that one i fould online.
4015X unbricked !
Hello,
I found a similar solution here (replace * with . to get a correct http link):
forum*gsmhosting*com/vbb/f317/ot-4015x-firmware-arabic-bulgaria-africa-kenya-1946694/index2.html
It took me hours to find good stock ROMs (bulgarian & arabian then french via OTU) !
You'll have to "play" with pro_info and scatter file...
Good luck to all to unbrick your 4015x !

Please can you explain how to use that firmware?
I think it's a recovery firmware for going back to factory defaults when s**t happens.
But I read on some forums that I should backup my IMEI and NVRAM (with MTKDroidTools or something like that...i don't know if there's a specific tool for the Cube T8 Plus) BEFORE trying custom roms, otherwise there will be problems even on restoring stock firmware, right?
Can somebody please make a short-how-to for dummies focalized on this Cube T8 Plus (so poor and confused support on forums yet)?
- Backup before custom rom installation
- Custom rom installation
- Recover to stock firmware
Another question: why that page you linked says "Platform: Mediatek MT6753"
Isn't MT8783?
Thank you very much
my tablet is not bricked now but my serial number and my mac adress is wrong ='(
Use sp tool for save your firmware tablet ( i think).
I have the same problem, after the resizing of partition the tablet is soft bricked and I'm downloading the stock firmware form the above link.
Is there any way to backup the mac address and serial number from softbricked tablet?
...you should have a backup of nvram!

I think it's too late.
I did a backup of nvram with SP Flash Tools BEFORE brick.
When i recovered the tablet after brick, my IMEI was invalid until i flashed my backup of nvram.
Anyone could suggest how and what to backup before trying Root and Resize?
Just backup nvram with sp flash tool

The only unrecoverable partition (for mediatek devices like T8 Plus) is the nvram which contains info about IMEI.
Firmwares/ROMS that we can download from the web never comes with nvram because it's single product related. It's like mac address of wifi cards.
You can find even stock (original) firmwares online, they will bring your tablet back to factory default after a brick.
But if the brick corrupted the nvram, you will NEVER be able to recover it. That means no phone calls and no data connection.
Unless you did a backup of nvram before its corruption.
With SP flash tool you can "read back" from your T8 plus the nvram partition and save it as a file on your pc (file size must be 5MB). Of course you need drivers, SP flash tool and the scatter file. Since i wasn't able to retrieve the scatter file from my T8 plus, I used the scatter included in the stock firmware T8-PLUS_V1.0_20151004.
I am new forum user so I can't post links, but google is enough.
That stock firmware is hosted by baidu, so use browser translation and register an account to get permissions for download.
Remember: in the firmware archive you only need the scatter file! It will tell to SP flash tool where the nvram partition starts and where it ends.
If you will need to restore nvram (e.g. after the unbrick) ,you will have to download to your T8 plus that nvram file with SP flash tool, but before you have to edit the scatter file and set "is_download=true" in the nvram section. Otherwise you will not be able to select nvram in the partitions list from the download tab of SP flash tool.
So the backup will consist in two files:
- nvram file (5MB) (nvram, nvram.img, nvram.bin, extension doesn't matter)
- scatter file with edited "is_download=true" for nvram section
