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.

THANK YOU! :highfive::highfive::highfive::highfive::highfive::highfive:
LOVE YOU MAN
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.

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.
Regards,
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 !

how to partition system storage space of onetouch pop c1?
hello
As i work for pprojects on my arduino, i decided in the same to flash my huawei y330 u01 for install software like i want and because i found the phone too slow.
the phone was in android 4.2.2 vB123. Now same version after flash failed.:crying:
My phone provider is free mobile
i took the rom made in a french forum and use sp flash tools. Like a newbie, i don't save my phone because where are no data so i don't read all documentations and i check the all options on sp flash so i erase my imie if i understand by erasing the nvram
i try different way to reinstall my imie but all failed. i have a official rom that i tried to flash with 2 computers in w10 or 7 but it's a update.app file and ctw don't take it. i try to unpack this file with a post take here. i also try :
imei repair,ingeneer mode,maei meta ,mobileuncul,mtktools,spflash tools in differents versions 3.x or 5.x ,sn write, nvram fix
so i have few questions :
if i flash the phone with the official rom, can this repair the imie ? In that case, how can i restore with the update.app file is it possible to install the official recovery 3e ?
someone have a backup for an original phone just put the imie to null that i can install?
thanks for everything to try

Uncheck Preloader while other files checked and click on download then connect ur huawei and it should write VCOM XX(where XX represents a random port) in spflash tool.
Official roms are obtainable from huawei sites and there exist different versions but all look same to me ; u may also used a U05 variant on your U01 .

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
Thanks so much for your help. I think i will be able to backup NVRAM. But im kind of lost on scatter file editing and flash.
Im waiting for Tablet ti arrive
The following is a guide for repairing failed to mount efs and dm-verify fail (drk error)
We finally did it ~~~
Warning - We will not take any responsibility for your device. Follow the steps at your own risk. If your device is Knox 0, This guide would convert it into Knox 1 due to TWRP. For solutions that does not convert to knox 1 check out payed remote solutions. Everything on your device will be reset, including efs partition. You will need backup of efs.
Test on N950F binary 4 may work on other exynos models comment below if it worked for other samsung devices.
Problem Detail -
Bootloop with samsung stock firmware boot logo.
Recovery error E:Failed to mount /efs (Invalid argument) or dm-verity verification failed...
Device cannot boot into Factory binary or Stock Rom
Actions that could cause this problem -
Flashing a non-signed efs.img by odin
Corrupt flash of efs partition.
Note - Must have efs backup for device to work (very important)
Any error that cause bootloop would show in recovery required if
Files Required
Latest Odin (recommend 3.13)
Working Stock firmware and Combination file (same binary as bootloader)
PC
Winrar or 7zip etc
Solution for efs failed bootloop-
Extract Stock firmware AP file (rename .md5 to .tar)
Rename dqmdbg.img to efs.img (or smallest image must be smaller than 8000 KB). Extract Dqmdbg.img.lz4 so it’s just “Dqmdbg.img” and then rename it to efs.img and put that one in a tar. Other option is downloading a file that’s already made this way if your bootloader is binary 4, Saves you trouble of extracting / renaming: http://www.mediafire.com/file/589wucja9rk2v8f/efs.tar/file (if you download this file just move onto number 3)
Add file new efs.img into tar archive.
Flash tar as AP file in odin + download mode
Reboot download mode
Flash Combination with odin + nand erase option on Edit: suggest you to flash stock rom first and oem unlock, don't need to wait for 7 days if imei is 0000 skip combination step
Device Should boot into Factory binary
Use IME to restore imei using *#06# (or imei 0000 in stock rom) Edit: This step is not required if efs backup is restored successful
Your device should have dm-verify failed in recovery due to drk error
Continue drk bypass for dm verify error below to continue
Solution for dm-verify error (also known as drk bypass - but temporary read note)-
Extract Stock firmware AP file
Make a copy of boot.img and delete recovery.img
Note - if files is boot.img.lz4 format change name to recovery.img.lz4
Rename boot.img copy to recovery.img
Add all the files (including other files extracted) to tar.
Flash Modded AP file with BL, CP, CSC (nand erase not required)
The phone will boot into stock firmware
Note- cannot reboot, will stuck at dm-verify error again and need to flash modded AP again.
Wait 7 days to oem unlock phone or use 7 day bypass by changing dates (not always work, keep trying, don’t reboot, worked for Samsunguser932 Edit: Imei must be 0000)
Edit: oem unlock will fix drk - if not you must follow next step
Once oem unlock flash TWRP and restore efs backup Edit: if you haven't fixed imei fix now by *#06# with combination file
Flash stock firmware once again by odin (stock, not modded)
Done - phone is back to normal
If you cannot be bothered doing by yourself you can pay https://www.facebook.com/gsm.xraxxx/ to do this.
(after he used plexihub to fix phone, i believe he is using similar method. It doesn’t seem fair to post this guide as i’ll be damaging his income but it seemed also unfair to keep this as a secret. If you want to donate to me please donate to him and his team instead at https://spacial-file.com/ or paypal [email protected] Thx)

update: to skip 7 day oem unlock imei must be 0000
The best method for bypassing oem unlock for 7 days.
Requirements - clean phone with stock firmware, samsung account logged in, imei 0000
Go to setting and check for manual update. This will fail/stuck and oem unlock would appear in development settings

You do not need an efs.img to repair efs failed to mount. It is only required for the functionality of the phone (sim). This guide would work without an efs.img, it is recommended to install a custom rom after the guide. Even though this guide can allow you phone to work, but due to drk/dm-verify errors, it is currently impossible to restore the phone to the original state.
Note - you'll need to find someone that is kind enough to share a copy/backup of their efs.img g955F. Most people think it is illegal to share as the efs.img contain imei, but with cpid devices, the imei would be overridden by your current device. Most importantly you need to change the serial number in the SVC (or else you will have the same serial number as the person sharing.
plz my problem is oem lock on, frp on and drk error. i have combination file and stock can your guide work for me?

This would only work if you're still on binary 3. Follow the steps for DM verity fix with 7.1.1 firmware. Flash stock 7.1.1 with replaced boot.img using Odin and fix frp using adb (guides online to enable adb). Wait for 7 day OEM unlock (no method to skip do not restart). Flash twrp and use twrp to flash custom ROM or DM verify fix.
Note - this method would fix function ability of the phone only if efs is not corrupted. (If you had paid someone to fix efs, this would not work). Finally the phone will become Knox 1 and normal update functions might not work. Practically makes the phone unable to resell as a working phone.
Hello. My efs partition was erased by a z3x box. Or an octopus, I do not know. I followed your instructions. The IME combination is empty. I install a modified firmware, it works but I can not enter the Samsung account (crashing), I can not check the system updates (infinite device registration). Should I wait 7 days before the OEM unlock? Will it work?
@Alarg read post 2 to skip 7 days. Infinite device registration should make OEM unlock show with samsung account logged in. OEM unlock must be first done before installing modified firmware (suggest kernel). You must have backup of efs, a backup from another phone will not work.

I can't log in Samsung account (processing failure). Imei unknown, s/n 0000000000 This method does not work for me.
@Alarg Which firmware ver are you using?
Have you tried nand flash combination file and then flash firmware (before boot, hold download mode buttons so the phone won't boot to factory mode). I do not see a reason why Samsung account would not work, try another ver maybe the version you downloaded is corrupted.

The following is a guide for repairing failed to mount efs and dm-verify fail (drk error)
We finally did it ~~~
Warning - We will not take any responsibility for your device. Follow the steps at your own risk. If your device is Knox 0, This guide would convert it into Knox 1 due to TWRP. For solutions that does not convert to knox 1 check out payed remote solutions. Everything on your device will be reset, including efs partition. You will need backup of efs.
Test on N950F binary 4 may work on other exynos models comment below if it worked for other samsung devices.
Problem Detail -
Bootloop with samsung stock firmware boot logo.
Recovery error E:Failed to mount /efs (Invalid argument) or dm-verity verification failed...
Device cannot boot into Factory binary or Stock Rom
Actions that could cause this problem -
Flashing a non-signed efs.img by odin
Corrupt flash of efs partition.
Note - Must have efs backup for device to work (very important)
Any error that cause bootloop would show in recovery required if
Files Required
Latest Odin (recommend 3.13)
Working Stock firmware and Combination file (same binary as bootloader)
PC
Winrar or 7zip etc
Solution for efs failed bootloop-
Extract Stock firmware AP file (rename .md5 to .tar)
Rename dqmdbg.img to efs.img (or smallest image must be smaller than 8000 KB). Extract Dqmdbg.img.lz4 so it’s just “Dqmdbg.img” and then rename it to efs.img and put that one in a tar. Other option is downloading a file that’s already made this way if your bootloader is binary 4, Saves you trouble of extracting / renaming: http://www.mediafire.com/file/589wucja9rk2v8f/efs.tar/file (if you download this file just move onto number 3)
Add file new efs.img into tar archive.
Flash tar as AP file in odin + download mode
Reboot download mode
Flash Combination with odin + nand erase option on Edit: suggest you to flash stock rom first and oem unlock, don't need to wait for 7 days if imei is 0000 skip combination step
Device Should boot into Factory binary
Use IME to restore imei using *#06# (or imei 0000 in stock rom) Edit: This step is not required if efs backup is restored successful
Your device should have dm-verify failed in recovery due to drk error
Continue drk bypass for dm verify error below to continue
Solution for dm-verify error (also known as drk bypass - but temporary read note)-
Extract Stock firmware AP file
Make a copy of boot.img and delete recovery.img
Note - if files is boot.img.lz4 format change name to recovery.img.lz4
Rename boot.img copy to recovery.img
Add all the files (including other files extracted) to tar.
Flash Modded AP file with BL, CP, CSC (nand erase not required)
The phone will boot into stock firmware
Note- cannot reboot, will stuck at dm-verify error again and need to flash modded AP again.
Wait 7 days to oem unlock phone or use 7 day bypass by changing dates (not always work, keep trying, don’t reboot, worked for Samsunguser932 Edit: Imei must be 0000)
Once oem unlock flash TWRP and restore efs backup Edit: if you haven't fixed imei fix now by *#06# with combination file
Flash stock firmware once again by odin (stock, not modded)
Done - phone is back to normal

Note -
dm verify cannot be completely fixed, it can only be bypassed (in the system by flashing no dm verify).
You will need to wait for 7 days for oem unlock (there is no method to skip oem unlock)
Warranty will be voided (KNOX 1) - don't think there is a method to avoid tripping knox.
Suggest installing a custom rom after oem unlock (many reports that no dm verify on latest oreo does not work without root)

EFS partition is not touched when flashing roms (they actually do but in a safe way), only retards like I would try to mod efs partition.
Hi guys, will it work in my case? https://ibb.co/mJRcHK
Device is SM-N950N FRP ON and OEM ON.
What kind of solution should I follow?
@Anvar2005 - This looks like a drk verify error. Which binary are you on? frp bypass only works with binary 3. You will not find anything for frp unlock on this forum. Same steps for drk verify but use nougat.
