Hi there.
Following this howto https://forum.xda-developers.com/android/help/how-to-boot-sd-card-qmobile-z8-bricked-t3712171 , it seems that I need to have working phone in order to make dd copies of partitions userdata, system, cache, persist and misc. Can anybody provide me images of these partitions from working SAMSUNG NOTE4 SM-N910F ? Without that i cannot boot my bricked phone from sd card.
Thanks a lot for help.

Hello all. Somewhat of a n00b to android. I recently got the new nexus 7 (2013) and have been playing around with flashing roms and using a custom recovery. So i know how to do all of that now but my main questions are:
1. When flashing a ROM(ie CM) what partitions are affected? What is actually being flashed on the device? System partition? Kernel too? Because i notice when i factory reset and then flash a new rom, the same data is still on the internal storage.
2. I know that there's a system, dalvik, cache, recovery and boot partition. Well im trying to figure out what exactly does flashing a rom do? Is internal storage a separate partition from those main partitions?
I apologize if this topic has already been covered somewhere else. I have searched the threads and cannot find a straightforward answer. Thanks for your help guys!
Your device has a fake sdcard this your internal storage which flashing a ROM through your custom recovery does not touch
For the most part when flashing a ROM it will only write to the system and boot partition (occasionally data) but you should be wiping cache, userdata and dalvik and this may be in the updater-script if the ROM you are flashing.
Of course depending on the device there are lots of other partitions namely, bootloader (sometimes split between primary and secondary and sometimes even a third SPL) and recovery, some have a separate splash1, radio/modem partitions, and then you can keep going with a slue of others that aren't affected by a normal flash, a quick search will certainly find you a list of all partitions to your device

1. When you flash a rew rom, the files are maily written to system partition. User apps (or if you download from play store) are stored to data partition. Yes, kernel is being flashed, too! Try to open a rom.zip before flashing and you will see, which files are in which partitions.
2.On my old HTC Desire internal storage was a seperate partition. But on my HTC One i dont really know...wanted to know this, too Sometimes i think its not..
Correct me if i am wrong
Hope i could help you somehow! :laugh:
after installing an apps for galaxy s2, after restart my zenfone 5 ram 2gb lost it's partitions (it's erase something in my system folder). so, flashing via adb, fastboot,erase,format,factory reset,wipe,restore nand back up ( from zenfone 5 1gb, cause i didn't have nand back up) and other didn't work because partition of /system, /data, /dev, etc didn't exist. anyone can help me? :crying::crying::crying::crying: i just can use my phone in recovery and fastboot mode. someone say i must replace the motherboard. :crying::crying:
Hey guys I accidentally wiped some stuff in TWRP and now I need a backup that I do not have, so if someone can backup CUST, DATA ( excl. storage ), OEMINFO, PRODUCT, PRELOAD, PRELOAD IMAGE, VERSION, ODM via TWRP and upload it to AFH or Mega I would be grateful.
Thanks in advance.
Got it solved using this method - https://forum.xda-developers.com/ma...-to-update-huawei-mate-20-pro-locked-t3897480
Hello,
the situation:
* Upgraded from Oreo to Pie with Samsung Stock (June build)
* Flashed TWRP, no-verity, magisk, xposed (Ed) etc.
* then factory resetted (reasons not important)
Everything worked fine. Then I encrypted my internal SD card with the 9.0 Samsung Stock ROM.
Complication:
* I realized TWRP cannot handle encrypted internal storage from Samsung Stock.
* Now I can flash (with Odin) a Stock ROM and TWRP.
* But I cannot unencrypt my internal storage using TWRP
* This MEANS I cannot flash magisk via TWRP etc.
> When I go to TWRP > wipe > wipe data, TWRP formats internal storage (it is then not displayed as "0 MB" anymore)
> However, when I re-flash stock rom - the internal storage gets apparently encrypted again without me chosing the option
Is there a way out? Otherwise I have effectively killed my S9+ for root usage under stock rom (which I need for camera performance - sole reason I bought the s9+).
Thank you in advance.

So i realize that twerp is not capable of decrypting internal data storage for the s9+. But is it a bug? I mean there must be a way to just wipe the internal storage without being able to handle Samsung encryption??
//Edit
just FYI: installing the following ROM with the "_rescue" suffix as explained by the dev, solves the problem of the encrypted storage!

Ok so this is getting interesting.
1. Encrypting with Samsung Stock
2. Wiping Data (wipe "yes") with TWRP
3. --> Internal Storage accessible again - but no ROM installed
4.A.1. Reflashing samsung stock
4.A.2 Internal storage automatically encrypted again
4.B.1 Alternatively: Flashing DevBase Samsung Stock
4.B.2 Internal Storage still decrypted and accessible via TWRP
4.B.3 Wiping DevBase ROM
4.B.4 Flashin original Samsung Stock
---> Internal Storage encrypted again and not accessible for TWRP
Question: Does encrypting the internal storage via Samsung Stock once, trigger a flag that causes the phone to be permanently be re-encrypted if flashing stock ROM?
Is there a solution to this?
So i assume no one has encounter this ever before or has enough technical acumen to give a hint?
"_rescue" totally worked.

Thanks for the referral.
I was in the exactly the same predicament as yourself.
Flashing the latest XSG (UAE) firmware encrypted /data and I couldn't decrypt it.

Can Anyone help me, please? The phone literally itself without doing anything started doing a download(odin) mode loop. So I deleted data, dalvik, cache, system partitions without internal storage since it has very very important files for me and a lot of projects for the university!!! and before and after the folders in internal storage in twrp shows as random numbers and letters. I don't know why since when the phone was working normally I was protecting it by fingerprint and a password. And when I installed a stock ROM after it without wiping the internal storage. The storage is showing in negative. If anyone can help me this would be super appreciated and helpful. Thank you!
If there is a way I can use my password to decrypt the internal storage it would be insanely helpful!
