[Q] Problem With Flashing SCH-I535

The very first ROM I tried to flash was a version of CarbonRom. I was unsuccessful, as i got the installation aborted message. I then tried a couple of other lesser know ones, with the same luck. Lastly I tried CM 10.1, and with that, i had success. It was the only one that would work so far. Yesterday, I downloaded DU 4.2.2, and A new nightly version of Carbon (Specifically for my phone) With no luck of installation. Am i doing something wrong with these? Is there a different method of flashing i'm missing?

what is the procedure you take to install?
I usually go this route:
1) Boot into whatever recovery you have
2) Wipe Cache/Davlik
3) Install custom ROM
4) run a factory reset
5) Reboot

I have Philz custom recovery which based on cwm version 6.0.3.7 which when you tap wipe data you will then have the option to clean install for new ROM.

Sorry for not replying earlier, i never got a notification. I'm using the most recent version of CWM. My usual order is :
1. Boot into recovery
2. Factory Reset
3. Clear Cache Partition
4. Wipe Dalvik
5. Format /system
6. Mount /system
7. Flash new ROM

well we now have 3 custom recoveries to choose from I like the newer one since I can install a new ROM in fewer steps.

i would do a factory reset after you flash your rom too, can't hurt.
of course on updating the same ROM, I only Wipe Cache/Davlik and that's it.

Bad download? Does the md5 match?

after making sure you wiped everything make sure the download itself was proper I am running it flawless right now

Download your 4.4.2 firmware here
Make sure you have a good cable and the latest odin.

Do not panic. Is your phone able to boot into recovery? If so then there is hope.. Let me know and I might be able to help you out.
If you're in bootloop after cm12.. Try clearing the 'cache' and 'Dalvik cache' from recovery and try rebooting. .

I have a custom rom downloaded. But to flash it, I need to erase everything. That I am unable to do because the recovery dosent wipe data. It led to a bootloop. I got back the stock firmware and tried again and same result. Further more, I cant even factory reset. I'm using TWRP 3.0. Someone please help!

Ive tried that 4 times till now. It has been in a bootloop thrice. And I flashed stock. I currently am using stock firmware but want to flash the custom rom. The recovery is failing to wipe data because it is failing to mount data.

Try this
1. Reboot to recovery (TWRP)
2. Select wipe.
3. Select advanced wipe.
4. Check system.
5. Repair or change file system.
6. Select change file system.
7. Select format type.
8. Swipe to change.
9. Select repair.

there is one problem with stock rom. its encrypts the data partition right after installing stock rom, therefore twrp can't access data partition. i had similar problem earlier. this is how i managed to fix.
solution: http://forum.xda-developers.com/showpost.php?p=67980158&postcount=7
i suggest you to stick with stock rom, because right now whatever roms or recoveries are made for this phone are blindly ported (just copy paste roms). i have tried about 3-4 roms for this phone, all had major bugs especially battery related. there is only one developer who made a stable rom so far is beingtejas, search his thread. if you really want to use a custom rom, try THIS rom made by gaurav kesarwani with help of beingtejas that is why i am suggesting it you otherwise it didn't worked for me atleast.

[GUIDE] Flashing oreo roms on mi a1 without wiping internal storage.

Hello guys .
This is a guide to flash lineage os 15.1 or any other oreo rom on mi a1 without any fuss, bugs, wiping internal storage. And update it by dirty flashing it. I personally use this method and others have also used resulted in booting safely with zero bugs in the rom, no force closes.
So here you go :-
1- boot to twrp
2- wipe system,cache,data
3- check on which slot you are.
4- if you are on A, change to B (after wiping).
5- boot to bootloader and boot to twrp which I gave.
6- wipe slot B also. (System,cache,data)
7. Don't touch slots and boot to recovery.
8- just flash los15.1 rom from there and nothing else.
9- go to bootloader and again boot to twrp
10- flash gapps and boot to bootloader.
11- again boot to twrp which I gave and flash magisk.
12- reboot.
Enjoy. You have los 15.1 without wiping internal or downgrading to nougat or wiping internal storage.
So now here's the guide to update it. (Dirty flash)
(Remember to remove your pattern, pin, password before flashing or backing up)
1- Backup your data using twrp which I linked down below.
2- boot to twrp which I gave you.
3- wipe system,cache,data
4- check on which slot you are.
5- if you are on A, change to B (after wiping).
6- boot to bootloader and boot to twrp which I gave.
7- wipe slot B also. (System,cache,data)
8- Don't touch slots and boot to recovery which i have
linked down below .
9- just flash los15.1 rom from there and nothing else.
10- go to bootloader and again boot to twrp which I gave.
11- flash gapps and boot to bootloader.
12- again boot to my twrp and flash magisk.
12- reboot. Let it boot completely and skip the setup.
13- boot to twrp i linked down.
14-just restore your data backup and reboot.
Congo you have successfully updated your rom without wiping data and also whosoever is facing bugs like fp not working and other bugs use this method. Everything will surely work.
Anyone who has a problem can message me on telegram. Username- droidreboot

Have a good day.

If you're updating none of your apps or data will get erased. But if you are moving from stock oreo to this rom, it's like resetting your device. That's it. ?

You have ro to wipe data if you are changing roms. Like if you are on lineage, and you wanna install resurrection remix then you'll have to wipe system cache data in both slots. And if developer of lineage pushes an update and you're on lineage then you don't have to wipe data. I mean if updating you have to make a backup then wipe. Then after first boot restore that. Don't do this if you're changing roms. You'll get a bootloop

It says if you're upgrading from stock then wipe data. And if you're updating from old lineage build to new first make a backup then wipe and after first boot restore the backup. Read carefully.

[Solved] Help to flash custom ROMs

Hello everybody,
I bought a Oneplus 7 Pro a few days ago and I'm preparing it for my daily usage. It's my fourth Android smartphone, and the third Oneplus. So far, I managed to flash everyone of them, with no major issues.
And then, the Oneplus 7 Pro suddenly appeared
I used this tutorial to unlock the bootloader and flash the custom recovery.
From my understanding, the custom recovery is flashed in the Recovery Ramdisk and available for both A & B slots.
For now, I have A and B slots with stock OSS, unlocked bootloader, custom recovery and Magisk. All of this is working.
There began my problems. I want to flash a custom ROM without Gapps and I fail to do it. All instructions around ROM threads seems different to me, I don't get the thing about A & B slots, when I flash one rom, it boots as usual on the stock ROM, if I flash both slots, It causes bootloops and if I manage to launch the recovery, my internal storage isn't detected and I can't restore any backup.
I already used MSMDownload to restore the phone completely once.
Can somebody explain to my dumb person how to do it proprely ? Thanks in advance ! :fingers-crossed:
TL;DR : I fail to flash a custom ROM and make it work.

Yes I had same issues when rooted, it means you lost root. You can try tool all in one to flash recovery and magesik via fastboot. If that doesn't restore your access, on twrp you will have to type in format, then mount, then add rom to storage(this method wipes everything beware)

Thanks, I will try.
When you flash the ROM, does TWRP tell you that if you want to continue you need to reboot recovery ? If so, do you ? Do you reboot recovery on the same slot, or do you flash both ?

Nope, it doesnt tell you anything. Just reboot recovery from reboot menu. Don't touch the slot options

Thanks for your advices.
I'm trying right now, here's my steps :
- Wipe Data, Cache, Dalvik Cache (the standard Factory Reset)
- Install ROM : TWRP logs show that he's flashing on inactive slot A, then B. After that logs said " To flash additional zips, please reboot recovery to switch to the updated slot ". I'm going back on the menu
- Install TWRP Installer like previously
- Reboot Recovery : TWRP ask me if I want to install the TWRP App, I dismiss. After reboot of the recovery, it asks if I want to keep System Read Only, I swipe to allow modifications
- Wipe Data : Can't do it because TWRP is unable to mount storage. And after further investigations, I'm now on slot A, not B as before.
- Reboot recovery to slot B
- Wipe Data on slot B
- Reboot system
And It still booting on the stock Oxygen OS Rom, not the custom one installed before. I'm lost

The problem is that you are not performing factory reset.
Wipe data is not enough,you gotta go to wipe-format data-enter yes and swipe.
That is why you are getting bootloops and twrp unable to mount storage problem.
A/B is pretty simple.
You got two slots for many partitions like system vendor boot and all,but a single data partition.
Flash a rom from one slot,it always gets flashed to the other slot no matter what.So next time you reboot to recovery or system it's gonna be on the other slot.So here is the problem..one rom cannot decrypt data which was initially encrypted by another rom..so you gotta perform a data format instead of wipe.Thats it.

Well yes, I didn't understood the difference between Wipe and Format Data.
So let's resume :
Unlock Bootloader
Advanced -> Install Recovery Ramdisk : Install TWRP
Install -> Flash TWRP Installer
Install -> Flash Magisk
Reboot -> System : Reboot on stock OxygenOS Rooted
Then
Wipe -> Factory Reset : Wipe Data, Cache and Dalvik Cache, that means you just have to swipe on TWRP.
Install -> Flash ROM : Use the install function and install the ROM
Install -> Flash TWRP Installer : Don't reboot, go back and install as the previous step
Reboot -> Recovery : Reboot TWRP and it automatically load the other slot
Wipe -> Format Data : Click and type yes
Reboot -> System : Just reboot and it should load the installed ROM

is wiping internal storage compulsory?

Not wiping.. formatting..that is compulsory if your current data is encrypted

After multiple tries to verify the process :
Wipe -> Factory Reset + : Wipe Data, System, Cache and Dalvik Cache
Install -> Flash ROM : Use the install function and install the ROM
Install -> Flash TWRP Installer : Don't reboot, go back and install as the previous step
Reboot -> Recovery : Reboot TWRP and it automatically load the other slot
Wipe -> Format Data : Click and type yes
Reboot -> System : Just reboot and it should load the installed ROM
Install -> Magisk
Reboot -> System
Install -> Whathever you want
Reboot -> System
It worked !
