Lenovo A850 - system partitions resize - Lenovo A850

Hi, I tried to resize partitions downloading EBR files for that phone and nothing :/
Maybe someone can help me somehow. I tried HKPHONEROMEDITOR - it maked 4GB but 3.6GB is used - even if I delete all files and make hard reset.
Maybe someone have solution? Maybe someone have ROM, that is prepared?

can we partition memory?

good morning. please, the sdcard missing is a problem for we that want play with roms.... every time we have to save to pc before wipping.... is there a way for create a partition unformattable when we wipe for installing a new rom? where i can find something about? thanks
is there this possibility even with modded rom? every time you flash, have to reinstall all things from folder external?
In theory you should change gpt.bin inside firmware to change partitons memory scheme.
Edit: Nevermind

[Q] MTK (Mediatek) Repartitioning 101 gone wrong

Hello guys, for the previous year I would say, I have read about repartitioning MTK phones, starting with my old Cubot MTK6572 (Rest In Peace) to my current Doogee MTK6582.
I have tried countless times to repartition using the EBRTweak utility, or changing the EBR1 & EBR2 files myself but it never, ever works.. I always manage to get in the first initial boot and have a false victory where I see that I have re partitioned successfully, but after I reboot after, I always get a boot loop after that initial boot.
For editing the EBR files, I have tried:
-Using EBRTweak
-Editing myself by changing the values from scratch by making calculations with sectors, bytes and addresses
-Editing myself by
First adding a value in the /data partition length, adding that value
Second adding that same value to the start address of the FAT partition
Third removing that same value to the length of the FAT partition
For flashing the EBR files, I have tried:
-Flashing all the patitions with SP flash tools with the new EBR files (without changing the Scatter file)
-Flashing all the patitions with SP flash tools with the new EBR files (changing the Scatter file)
-Flashing only the EBR partitionsa on a working ROM
-Flashing the EBR files using an updater-script via a custom recovery
With each of these methods, all my calculations were exact when I verified everything (to the byte), including using "disktype" command in Linux.
So after one year of failure, I finally decided to post on XDA to ask for help... please, please, does anyone know why the first boot works but the second boot always ends up in a boot loop? :silly:
I emailed Doogee engineers and they told me that u cant re-partition it

Some phones (Notably the Mediatek "MTK" phones) are known to have a very small internal storage for your applications.
This is because the storage usually attributed to applications 6GB on the MTK6582 is split in two parts:
1- 1.3gb for applications
2- 4.7gb for an internal sd-card to put music and movies
But nobody uses internal sd-card much, because we all have external sd cards of 32gb or more. This means that you have a 4.7GB that is completely unused and an internal storage for applications of 1.3gb that gets full as soon as you install a few applications like Facebook, Youtube (that use a LOT of space nowadays), or update your system apps.
All this is completely ridiculous so a few people and I are trying to make repartition and have more space for application, while getting rid of that useless "internal sd-card"

yeah that's what I'm saying, I talked with MTK engineers but they just replay with "if you re-partition your phone, it will brick" over and over, I told them to just give me a solution, like changing EBR files or something, and I know how to unbrick MTK phones, but they didn't care at all, the problem is: why they just put all the storage as an internal storage instead of phone storage and internal storage, it's pathetic to put phone storage and SD card storage at same time...
WOW! You actually managed to talk to them? That is awesome, we could have a lead here, don't let that go, friend!
I'm happy that you agree with me however and all the thousands of people with the same problem. Maybe if you tell them that you don't care about bricking your phone and the warranty, that you just like to play around and you have a backup phone anyways (to convince them to answer).
You could tell them that the repartitioning works on the first initial boot, but ends up in a boot loop after you reboot a second time. If they don't want to tell us how to fix it, they could at least tell us why this is happening so we could research on the subject.
Thanks for your help, I'll hit "thanks" on your post!

Would appreciate some help on recovering files.

Hey, Had some trouble with my samsung galaxy s5 ... wouldn't boot properly after failed root-attempt.
So did a factory reset, works again... but obviously I lost all my pictures and videos.
Did some research on the subject and made a full raw dump of the internal memory over wifi.
So that left me with a raw image file, wich I then opened with UFS explorer pro recovery, it showed me the different partitions etc,,, and I can search/recover ... but I can't find any of my pictures/movies...
My question is ... does a factory reset, also wipe all internal memory so that recovery is impossible ? or did I make some mistake ....... after the dump I tried som APK's for direct undeleting files on the phone ... no joy
Can someone help me in the right direction ?

Your pictures ate gone. Factory reset make your device exactly as it was out of box.

That would mean that a factory reset wipes all your data, iow does a full format... as the data-partition is actually a file, then it resets all bytes in that file ???
That just makes me sad

[Completed] Soft Bricked Irulu with MT6582 Set

Hey guys, its been a long time since I've been on here asking questions, but I am completely stumped. I got an Irulu Victory 1S china phone. I achieved root, installed CWM. Problem was there was not enough storage space on main drive, as it was partitioned at 800mb for system apps and 5gigs internal SD storage. I found an app specifically for that phone manufacturer that partitioned the drive to 2.5 gigs. Flashed new Rom, Cyogen, now I am stuck in a boot loop. I can get into CWM no problem. But no matter what Rom I install, even after clearing delvik, cache, system, it just boot loops. I found from manufacturers website the original disk img files, but when using MTKtools it says disk size doesn't match file. I found a a blog that has a more detailed instructions on how to modify MBR and EBR1 using editors, but nothing on how to fix size issues. Any help is appreiated. I have win10 and Linux Mint systems if that helps any. Im assuming that there is a file or something I need to edit to get new roms to boot. I can do remote desktop sessions as well if needed. Im not computer dumb, but I know enough to get around windows and linux.
PS: I can only boot into recovery, when I ADB Shell it, it comes up as 123456789ABCDE RECOVERY as device. Cant seem to pull or push any files this way.
Update; Ok so I tried using EBR edit tool. Modified EBR to 2.5 gigs. Did a system, cache, and delvik wipe. Tried to install rom. Now it finds package, starts to open it, and then goes back to CWM main page. Tried several Roms with same results. It starts to install, but then flashes back to main recovery page. Now Im even more confused!
Hello,
Best bet is to get your partitions restored to factory partition table and then try flashing the stock firmware.
When in recovery, have you tried doing a full system and data wipe with the advanced wipe options and then flashing your ROM?
I'm not familiar with your device to give you better answers. Try posting your question in the forum linked below.
