Dirty flashed Pure Nexus 7.1.2 from 7.1.1 and got the System UI has stopped error

Hi,
I dirty flashed Pure nexus 7.1.2 from 7.1.1 and got the System UI has stopped error, so ended up having to revert back to 7.1.1 thru TWRP backup.
I followed this procedure:
Download the latest Pure Nexus zip, your choice of root zip (optional), and your custom kernel (optional) onto your phone.
Boot into TWRP and make a backup (optional but HIGHLY recommended).
Wipe cache and dalvik cache (optional).
Flash Pure Nexus zip.
Flash root (optional).
Flash custom kernel (optional).
Reboot and profit.
What am I doing wrong? Might it not matter the as the diff between the two versions being small?
Thanks for the help.

Backup all apps through Titanium Backup and just clean install. Flash zip and Gapps, reboot. Go back into recovery flash root zip and kernel zip reboot go to Titanium backup and restore apps. Done deal!

Wipe cache and dalvik cache is never optional. If you didn't, reboot to recovery and do that.
If you flashed a third party kernel, dirty flash the ROM again, don't flash the kernel but do wipe cache and dalvik cache, then boot and make sure everything is ok.

Do I need to install GAPPS?

Gapps are not essential to running a ROM successfully, they just provide other features to use. I always flash some form of Gapps just so I have other functions not included in a ROM.

What functions are added? I always manually install Gmail and Maps.

There are different Gapps packages that provide other features. Base package installs google play services and the like. Look up Open Gapps on the internet and you will see what's available.

I want to use this rom again, but i'm on Pie, now. Can i dirty flash over my current rom, o i have to clean flash it?
This will encrypt my phone again?

You MUST clean flash between ROMs. Also between major versions such as 7.0 -> 7.1 or 8.0.
Encryption is all about the kernel and whether the force encrypt flag is removed. Without the forced encryption flag, a decrypted user data partition stays decrypted. However, the same kernel will not decrypt a currently encrypted user data partition. That requires using Fastboot to wipe the partition and making sure the kernel will not re-encrypt on boot.
Using Pure Nexus will not force encrypt your device.
Flashing a stock ROM definitely will.

Bring light into the darkness of encryption

Hi togehter,
I had some problems with flashing new custom roms and ended up in a bootloop with not being able to boot to recovery. This could be solved by flashing the stock image with the xiaomi flash tool.
Before I will fu up again I would like to bring some light into the darkness.
When coming from Stock Rom:
1. Unlock Bootloader -> done successfully
2. Flashed TWRP Recovery -> done successfully but storage (data) was encrypted
3. Flashed Magisk via Recovery -> done successfully (storage still encrypted)
from here I was happy using the Stock Rom with Root.
Now I started messing things up:
Because there are a few things that bother me about the stock rom i wanted to use lineageOS/Pixel Experience. So I proceeded as following:
1. Backup my data (still have to enter key when starting twrp to decrypt the storage) -> done successfully
2. Flash LineageOS -> resulted in bootloop to TWRP
When entering twrp there was no query about the key and data where encrypted. Also the Backup was not accessible .
3. I used all in one tool to erase storage and decrypt data. -> successfully... Now i was able to place data on the internal storage again and start flashing a rom
4. Flashing LineageOS -> done successfully and able to boot into rom
Back to TWRP data was encrypted and I had to enter key.
5. Flashing remove force encryption script via twrp. -> done but now i was facing boot to black screen. TWRP was not working anymore.
Only way to get it work again, was flashing stock image.
Why is the data system always encrypted. This is rly annoying and backups don't work, because i can not encrypt them. Also, I can not put any files on the memory because it is encrypted.
I would rly like to try a custom rom, but I would also like to be able to go back to a backup. What have i done wrong?

You have to flash no dm verify right after formatting data & flashing rom. Don't let it boot.
I would recommend using the stock firmware. Los/AOSP is rubbish for our device, it's too unstable, lacking features and has worse gestures.

You need to format data (not just wipe data) in TWRP. Some people suggest before flashing a ROM and some say after, but I don't think it makes a great deal of difference either way.
Make sure you either flash the appropriate firmware and vendor recommended, or the fastboot ROM of that version.
Then in TWRP wipe cache and dalvik, then format data.
Reboot into TWRP, or unmount and mount the data partition in TWRP so it correctly reads the data partition.
Copy across the ROM (and GApps if needed)
Them flash.
Boot into the ROM and you should be good.
After initial setup, if you want root, boot into TWRP and flash Magisk.
From here, if you've set a pin on the ROM, you'll be encrypted, but everything should still work normally. You should be able to access everything normally in TWRP and also perform backups. You should be able to got data across from/to a PC normally.

Not true in many ways.
There is need to flash no dm verity. It's one way of solving the issue, but it's not the only way. You should only do this if you know what it's for and if you know you want this.
AOSP ROMs are not unstable. I've been using them on mine for over 4 months. None are perfect and they have a few minor issues/bugs, but they are far from being considered unstable. I've never had shutdowns, reboots or FC'S.

Thanks for the replies.

So for example with LineageOS 17 I can use the global vendor and firmware, but sometimes in the thread it is recommended to use chinese vendor and firmware. In this case I should flash another vendor and firmware then the global one.
What do you mean with a fastboot rom. How can I identify one of them?
Is the MiuiMix Rom a fastboot rom. This one changed my vendor and firmware. After flashing this rom, my bootlogo changed to redmi... Am i right with this suggestion?

Fastboot ROMs are official ROMs that are flashed through the Mi Flash Tool
, with the phone booted into fastboot mode and connected to the PC. They contains almost all partitions, including vendor and all firmware. They will be a .tgz file. They are mainly used as an almost failsafe way to recover the phone, should you mess things up. Flashing them will restore the phone to factory, so will lose TWRP, but you're guaranteed a clean starting point.
If, for example, you want to install Havoc 3, it is recommended to flash it on top of either China or India 10.4 vendor and firmware. So if you're phone is currently on global firmware, you would then need to flash, say, Chinese firmware and vendor flies, before flashing Havoc.
If you have been previously flashing other mods, such as 75Hz, screen refresh rate, for example, then you might choose to flash the official Chinese fastboot ROM, instead of just the firmware and vendor, to ensure that you've cleaned the phone of any mods, etc. In most cases you will be fine flashing firmware and vendor, though.
Miuimix is a custom ROM, which is based on the official China MIUI ROM. Because it's based on the China ROM this is why the logo changed to Redmi.

So in this case, i can just flash this rom and there is no need of flashing a diffrent vendor or firmware.
So final question: I'm happy with the stock rom plus root. I would like to try a custom rom but I'm not willing to go through the whole installtion procedure again. Is there a way of making a backup and keeping it?
When I backup the stock rom right now, the backup will ne encrypted again...When I formate the data, all my data will be gone again ?

Custom Rom flashing problem.

Okay. Am currently on MIUI 11.0.3 (the latest one available for RaphaelIN)
So, the problem am facing is that, when i flash a custom rom, my phone gets rebooted to recovery and sometimes to fastboot(this happens occasionally) and i just simply cant get the rom to load.
Sometimes my phone gets into a state which resembles hardbrick (none of the buttons work, even holding the power button for 10secs doesn't) and after sometimes, usually 15 to 20 mins it restarts itself. This has happened thrice till date and all while booting to system.
The Roms i have tried-
-Pixel experience (unofficial) (android Q)
- Lineage OS 17 (unofficial)
- Havoc OS (both official and unofficial) (both pie and Q versions)
-MIUI (European rom)
I have also tried flashing the chinese, indian and global vendor (all done separately) thinking it was a vendor issue, but it also doesn't work.
Recovery is TWRP latest version, have also used orange fox recovery
Bootloader unlocking was done through the official method and the official app.
Any solutions for this problem and has anyone faced these problems or is it only me?

Consider this an overkill solution that always works for me if I run into issues with other methods. It will wipe everything so backup your data and apps.
Download the latest fastboot Indian MIUI ROM (for anyone else reading this download the ROM that is the same region as your phone)
Fully extract the ROM and flash it - make sure, if you use the Mi Flash Tool, that you change the flash option to 'clean all'
Boot into MIUI once, you don't need to actually go through the set-up, just let it fully load.
Boot the phone into fastboot and install TWRP - I recommend the latest mauronofrio TWRP.
After installing TWRP boot immediately into TWRP.
Format the data partition - don't skip this step.
Wipe cache and dakvik - don't wipe anything else.
In TWRP goto the mount menu and unmount the data partition then mount it again - others would suggested rebooting back into TWRP, either way works, you just need to make sure the data partition is properly mounted after formatting it.
Install the ROM of your choice - either have the ROM on a USB OTG stick, or copy it onto the phone from a PC whilst still in TWRP.
If your ROM doesn't include Google apps and services and you want Google, then install GApps - at the time of writing this Android 10 GApps is still in beta and packages bigger than nano may cause issues, so stick with pico or nano, assuming your installing an Android 10 ROM.
Boot into the ROM.
If you want Magisk, once the ROM has loaded, boot back into TWRP and flash the latest Magisk installer - it is possible to flash Magisk without booting into the ROM first and you'll probably be OK, but occasionally it can cause problems, I can't remember the details, but for the sake of 30 seconds I now boot into the ROM before flashing, just to be on the safe side.
At the time of writing this people have recently reported issues flashing GApps immediately after flashing Havoc 3.0 and recommend booting Havoc before flashing GApps. Although others say they've not had any problems. So if you choose to install Havoc you 'might' have problems if you install GApps without booting into Havoc at least once first.
I've never had problems when following this method.

You didn't format data that's why your rom doesn't boot. Follow Robbos nice guide and you are good to go.:good:

I did format the data partition coz that's one thing I and my friends always do when flashing new rom. I don't exactly remember but i think, the pseudo hardbrick thingy started after i formatted the system, data, cache & internal storage.
I will follow Robbos guide adn keep you guys updated on what happened.

Guys i need your help,, i flashed my phones custom Rom tecno 7cs using sp flashing tool.
That worked and it showed the tick icon on my pc.
The problem is that it does nothing to my phone because the software issues are still there
my phone keeps restarting itself almost all the time and sometimes won't even boot it takes longer to boot,,, apps keep on crushing and many more.AM tired am going to break it and throw it if i don't get solutions asap!
So the flashing process only wiped data on the phone nothing else whatsoever.
tecno 7cs p121 Bi safaricom ke 20151111

(GUIDE) Flash Roms correctly if everything goes wrong

So as you guys know there are a lot a lot of ways to flash a Rom here on our lovely OnePlus 7(Pro).
Many people get it to work but many - me include having Problems with it, so i tested some ways to flash it and i guess i found a really good solution for it,
Btw there are less problems flashing the rom when the device is decrypt.
First of all make sure you installed the latest OOS on BOTH Slots (beta works too) and now just follow the steps.
1.) Factory reset
2.) Flash Rom + Twrp Installer
2b) FORMAT DATA (everything in your storge will be gone, so make sure to back it all up)
2c) reboot recovery
3.) Flash Rom + Twrp Installer
3b) FORMAT DATA
3c) reboot recovery
4.) Flash Gapps (optional)
4b) flash Twrp (just in case you lose it)
4c) reboot system
5.) The rom should now boot up
I hope i could help you out with that little Guide.
And make sure you FORMAT Data! Not WIPING it, cause in most cases this is misunderstood

Are you booting into MIUI at least once after flashing it, before flashing anything else?
I've stopped doing the mount/unmount. I now always reboot back into TWRP after formatting data, seems more reliable.
In TWRP do a factory reset, then format data, then reboot back into TWRP.
After this install the ROM you want

If you want to flash something else, remove lockscreen security first before flashing. This should allow you to dirty flash an update, or clean flash a new ROM, without problems. You only need to format data when flashing over MIUI.
If you get into problems and you cannot successfully get a custom ROM working, this is when you need to flash MIUI first.
You only need to flash vendor/firmware files when the custom ROM recommends/requires a version that is different to what you currently have.

The emoji's screwed up my reply. Try again.
1. Next time create a new post, don't resurrect a vaguely similar old post.
2. Restore MIUI with a fastboot ROM and try again. Use my guide here to help you install the ROM of choice.

If you're not sure what you're doing, follow the guide exactly, do not freestyle.

1.Install any rom
2. In recovery factory reset or change data partition to ext2 and then again back to ext4
Reboot
It will boot.

Seriously?

Hi, I am new to K20 Pro, I have not unlocked my phone yet, I was just going through the forum, to understand all the things and how flashing is done in K20 Pro, I have a question about flashing the vendor, some ROM require it & some don’t, can anyone explain? And how do I choose the correct vendor for my device?? Where can I download the right vendor??
Thanks!

When flashing you will actually need vendor and firmware files together.
These are taken from the official MIUI fastboot ROMs. You can find them repackaged in a single flashable zip file from here.
https://downloads.akhilnarang.dev/MIUI/raphael/
Flashing one of these files in TWRP is the easiest way to go.
You can also find then repackaged as separate zip files from here

This site has a much greater archive, so is good if you need an older version that you can't find in the other site. You will need to make sure you download vendor and firmware files for the same version.
You should always stick to the version that is for the region of your phone. e.g. Indian vendor and firmware for an Indian K20 Pro, etc.
Some ROMs use an OSS vendor and so this is included as part of the ROM install. In which case there is no need to flash the MIUI vendor.
When a new version of MIUI is released, vendor and firmware files might get updated, to fix a bug or to add extra functionality. In this case some custom ROM devs will include them so that they get the bug fixes or extra functionality in their ROM too. When this happens they will update the minimum vendor and firmware version requirements for their custom ROM - the version will be the actual MIUI version in which the vendor and firmware files were updated.
Where a ROM doesn't specify vendor and firmware and doesn't have an OSS vendor, then it normally implies that any version will work that is from MIUI based on the same Android version. In this case use the most recent version, which you will already have if you've kept up to date with MIUI updates.
When installing a new ROM, you will only need to flash vendor and firmware files if your current version is less than the required version of the new ROM.
