[Recovery][BKL][EMUI 8.x][Unofficial]TWRP 3.2.1-0 working recovery from View 10

Backup your stock recovery per this post. If you are too lazy, I can upload my backup from .104 build (C432) to Mega.
Download twrp_bkl_0.7.img from this post and place it in same directory with your ADB.
After successful backup as precaution disable any locks like pattern/PIN/password/fingerprint, reboot to bootloader (fastboot):
Code:
adb reboot bootloader
Then flash new TWRP recovery:
Code:
fastboot flash recovery_ramdisk twrp_bkl_0.7.img
After successful flash reboot device and immediately after confirming command below unplug USB cable and HOLD and keep holding VOLUME UP button, if you won't the new recovery will be overwritten by stock and you can try again.
Code:
fastboot reboot
Tested by myself on Honor 10 8.1.0.104 (C432) with unlocked bootloader and installed already Magisk 16.4 with Magisk manager 5.7.0, Magisk ramdisk persisted after installing TWRP recovery, system boots normal.
Next step after unlocking BL, installing Magisk, installing TWRP recovery -> flashing GSI AOSP, LOS or RR. Only reason I bothered with installing TWRP was that GSI image of LOS and RR don't include opengapps, only AOSP does, so without TWRP you can't have opengapps with these two GSI ROMS.

Nice work. ?

tried to install GSI RR OS, but ending in bootloop, also even after resizing system partition to maximum (TWRP / wipe / resize) opengapps still showing error 70 about insufficient space (which makes no sense, so they really seem to have wrong detection of A/B instead of A for Huawei/Honor devices), though these gzr gapps seem to install successfuly, now if I could figure out the damn bootloop
potential reasons for bootloop - previously installed magisk, wiped also system not only data/cache, installed through fastboot while TWRP there and not only stock recovery, ???
edit: i guess will try flash GSI through TWRP again, quite a waste time to wait each time like 9-10 minutes to find out it can't boot
edit 2: so even flashing through TWRP doesn't help, just stuck on android animation for 10 minutes and then it restarts (and even if you do fatory reset through huawei erecovery it doesnt change anything). maybe can try to restore everything and not wipe system before installing, just factory reset through TWRP (though I remember I read somewhere it's not reliable and it is better to do it through system, but I think that one wipe also internal storage which I wanna avoid)? back to rooted EMUI with TWRP for now, don't have time to try various combinations
edit 3: flashing over TWRP backup without wiping system doesn't help, so it seem it's gonna be magisk or replaced stock recovery i guess, otherwise no idea

BTW the lack of feedback here and trying from other users it's very depressing. they boasted million phone sales and i am the only one in the whole world trying to install TWRP and GSI ROM on this phone?

Don't be disappointed the lack of feedback from users is not many power users have got their hands on this model.
And also we are having different builds.
From the day one I am trying to rebrand my device but no success .
Once I have rebranded to EU I will try and let you know.
Did you flash open gapps nano package through twrp in gsi image?
Did it give you the same error?

tried just pico opengapps as on all phones i flash, that's the smallest, but always end up with error 70 not enough space despite resized system partition in TWRP and many GB available, the other unofficial GZR zero gapps build i mentioned seem to be flashed successful in TWRP, but in any case no luck with booting

Did you format your phone before trying GSI ?
Try formatting phone and remove some system apps and then flash gapps it will mostly solve the problem.

Don't be upset – e.g. I didn't receive my Honor 10 yet. You won't be the only one for sure, you're just the first one to do it, which is super nice for others because it motivates them to do so as well!
Just wondering: does it make a difference for TWRP wether I own the 6gb or 4gb version?

I did factory reset (data, both cache) and also wiped system partition, gapps would be the least issue, as I said that GZR should work, but my system doesn't boot, no matter how times I wipe everything through TWRP or stock recovery after flashing system.img, since they say it's normal to hang at first boot and then wipe and then it should boot, but it doesn't work for me. also of course tried to power off phone since some people said it helps to do it after flashing. what I haven't done it's fastboot -w which should be some better wipe. some people say also you should remove magisk ramdisk, though I forgot to back up original, backed up just stock recovery. and also I haven't tried to flash everything with stock recovery, though first flash I did was through fastboot anyway and not through TWRP and it didn't make difference
so last few things left to try:
- fastboot -w for total wipe of data (better than TWRP? though it should be same as Format data in TWRP which wipe everything including internal storage which I wanna avoid since backing up 15GB TWRP backup file it's kinda annoying and my system has problem to do it)
- flash with stock recovery (I have backup, no big deal)
- remove magisk ramdisk and flash with stock ramdisk (forgot to make backup, can't replace)
though I am tired of it for now, spend last night like 4 hours dealing with it until 2AM and I also need to take care of children

I don't think RAM has something to do with anything, but that sounds like Chinese version since EU has always 4GB and only difference is storage, so you will have different ROM

So I just read more about the GSI/Treble stuff and it said somewhere that modifications like Magisk probably lead to problems with the GSI flash.
Which is why I would try to get rid of the magisk ramdisk first.
I'm not an expert in this at all but maybe this helps.

yeah, now if someone could extract for me from 0.104 firmware for C432 that stock ramdisk, because I have some problems with mega to download it and I just need the stock ramdisk, nothing else, I have stock recovery backup but forgot to make ramdisk backup
edit: completely forgot there is option to "Completely uninstall" in Magisk manager, so tried it though even after restart with magisk manager missing i could still use root apps, so not sure how exactly this "complete uninstall" works, but anyway giving it a try after this and wiping data, installed system.img again, again wiped, rebooted and as usual loading and loading and nothing, seem can't further continue without copy of stock ramdisk to flash, tried downloading the big update from mega to extract it but it always fail for me to download, same with trying to copy my TWRP backup because for sure ain't gonna doi fastboot -w and setting up everything from scratch in case even this doesn't help, if I knew it works for sure and it will load new system which I will have to set up then no problem, but in this case...
edit 2: tried to replace magisk ramdisk with ramdisk from Honor View 10 BKL09 (same as our working TWRP) but it seem I end up after flashing it, wiping and flashing system.img in TWRP/erecovery bootloop, it's not showing android booting logo like before (but hey at least no need to wait 10 minutes to find it's fail) and either go to huawei ercovery, if I perform factory reset there then it boots to TWRP, but can't boot anywhere else besides these two

pass
I requested this image. Recovery has been established. When I enter the recovery, it requires a password to decrypt the system partition, I enter it (the same after switching on the phone), but a message is displayed that the password is incorrect. help me please.

told you in OP disable all passwords before flashing

The problem is currently we don't have full
ROM to revert to stock and if we brick our device there is no proper way to revert to stock.
Our model even doesn't have SD card support.
Just wait for some time for someone to provide proper way.

When i flash a treble rom, I have a bootloop. I returned back with eRecovery directly on the phone.

We do have a way to download full ROM.
http://pro-teammt.ru/firmware-database/?firmware_model=COL-L29C432
1. Search here for your exact model (change numbers after C432 to find ROM for your phone) and search for your rom version (B104 or B120)
2. Double click on "filelist" on the same row as FullOTA-MF
3. From filelist link menu download update.zip file (it should be really big, like 2+GB)
3. Extract UPDATE.APP file somewhere (eg. Desktop)
4. In settings of HuaweiUpdateExtractor (link: https://forum.xda-developers.com/showthread.php?t=2433454) uncheck "verify header checksum" and open UPDATE.APP
5. Extract any img (Be it ramdisk.img, ramdisk_recovery.img or system.img) file that you need from UPDATE.APP via HuaweiUpdateExtractor
You just got whoole stock rom and img files that you can flash. Tested by myself with flashing back original ramdisk, ramdisk_recovery and system.img and everything worked well.

Complete setup of Lineage OS

Since in my last post I made a complete mess out of my first time trying to root my K20 and install lineage I wanted to my make a separate post so that I can list all the steps I need to take to correctly setup my phone how I want it.
What I actually want
A rooted device
Lineage OS
Minimal excess files (A clean Install)
Current Steps
Unlock and flash recovery
Backup
Format Data! (It's important if you come from Miui)
Install Q Firmware + vendor
Install LineageOS followed by gapps
Reboot into system and setup device.
Reboot into recovery and flash magisk
Profit???
Feel free to tell me how stupid I am and what I need to add to the list or steps I should take to make this process better.
I also dont know if its possible to get recovery and rom on android 10 versions.
Thanks

Did these steps not work?

They may work as it but I was just wondering if anyone could go into more detail or if there was a better approach and from what Kollachi said there clearly is a better way that what I said.

Since I'm in stock ROM and haven't ever flashed AOSP ROM in this phone I'll just back off lol

I like the details steps but I have a few questions.
(Unlock and flash recovery) From what I can tell there are two recovery's Orange fox and TWRP
(Format data) Just format data or are there other sections I should format/wipe
(Install Q Firmware + Vendor) I have no idea what Q firmware is or what vendor you are referring to
(Install Lineage + gapps) Is there a specific version from the Mi 9T pro since the official site doesn't list it

Any of the two recoveries will work. Q firmware means Android Q. Wile data/cache dalvik that's it. Regarding firmware, there's a clear topic of Lineage OS in K20 Pro forum which is still in unofficially state

1. You can take what you want. Orangefox is based on TWRP.
2. Format data is needed if you come from miui. If you did it you are good to go. But it wouldn't be false to wipe system, dalvic, cache
3.https://downloads.akhilnarang.me/MIUI/raphael/ --> Take 10.4.6.0 or 10.4.8.0 (Android 10 = Q)
4. No there is no specific version.

I would recommend the latest TWRP from here
https://forum.xda-developers.com/k2...icial-twrp-xiaomi-redmi-t3944363/post79823568
The dev is an official TWRP dev, so this version, or something very close to this, is likely to become official in the future.
OrangeFox is a heavily modified TWRP and has a lot of added functionality specific to MIUI. If you wanted to stay on stock MIUI, but debloat and have root, etc. then OF would be the better choice, as it has functionality that lets it play nicely with MIUI (it can remain installed when OTA updates are installed)
As someone new to flashing on Android, I would suggest downloading a 10.4.x fastboot ROM from the site I pointed to in your other post, then follow the same procedure to flash the ROM.
Make your choice based on Kollachi's info and what's important to you (HD Netflix - choose Indian, or a working NFC - choose Chinese)
However you MUST change the flash option to 'clean all'.
At this point you've got a nice squeaky clean starting point.
Boot into the ROM at least once, though it's not necessary to go through all the setup.
After that follow Kollachi's steps but you can now ignore the step to flash vendor and firmware as it's all part of the fastboot ROM already flashed.
Wipe cache and dalvik, format data.
There is no official LOS for this phone yet. Hopefully it will go official in the future.
For now just get the current Android 10 based LOS from here.

When ever I think I have the process memories and I follow the steps on my screen I still somehow **** this up and I cant understand how.
My current steps include
Flash the fastboot with the ROM that you linked me in my first post
Flash the recovery with TWRP (Every time I have then tried going back into TWRP is failed to work and prompted the original MIUI recovery)
Install the TWRP zip from custom recovery to try and fix the issue above (Only had this work once on orangefox and then never had success again)
So now I try to just flash the recovery and boot to it using CMD and it works fine
Move the lineageOS files from my PC to the phone SDCard
If I wipe data and the caches as suggested then the lineageOS zip is now go and I am back to flashing the fastboot ROM to restart the process
I know this might seem like im either stupid or just not getting it but could you or anyone else please make a bullet pointed list with links to what I have to download in order to actually achieve this since I cant do anything correctly even when trying to follow the steps.
(Im going to sleep since I have been trying to do this for hours now and I will check reply's in the morning.
Thanks for the help so far EVERYONE

I just told you what I have done and I'm running it so far without issues.
Robbo just said you should flash the whole Chinese or indian rom but I don't like his steps because:
1. File is much bigger
2. MiFlash is just meh
3. If you forgot to change the flash process you are bricked if you don't take the correct firmware for your phone.
Default option in Miflash is set to "Clean all and lock". Every time you use it, you will need to change it into "clean all" or something other.

Yes flashing the whole fastboot ROM does add the risk, if you forget to change the flash option, but you are guaranteed a clean slate and so less likely to have any niggling issues that nobody else has. I would bet large sums of money that many of the issues you see on here, where only one person has some problem and everyone else is fine, would be solved by fastboot flashing MIUI before installing the ROM of choice.
If you know what you're doing and know when you'll be OK with what you've got and know when it's best to start clean, then going with the vendor and firmware is easier.
But if your unsure and new to flashing on Android phones, I will always suggest go with the overkill and know you've got the clean slate to start with.

It's sounds like the main issue is stock recovery is being restored. This is something that MIUI will do when it boots up.
When you first install TWRP you cannot boot into MIUI before booting to TWRP as you instantly lose TWRP. So you need to boot into TWRP first in order to do something to prevent it being overwritten.
Options are
1
Code:
fastboot boot TWRP.img
2 Use the button combo whilst still in fastboot - power and vol+, hold both until the phone vibrates and the initial logo appears.
Now to keep TWRP you need to either flash a custom ROM, flash Magisk or flash the dm-verity script.
In your case you want to flash LOS, so now you've booted into TWRP go ahead and continue with the steps given.
Also, wait until after you've formatted data before copying everything over. You can access the phone as an MTP device when in TWRP, so you'll be able to connect it to a PC and drag everything across, or you can stick everything on a USB OTG pen, if you have one, TWRP can read data from them too.

The exact problem I have is that I cant transfer any files to the device after formatting the data. I follow the steps correctly and I get into TWRP successfully and then everyone has told me to format the data then install lineage but I cant install the OS if formatting the data removes it.
Get device into fastboot
Flash revocery with TWRP
power the device off
hold volume up and power
boot into custom recovery
format data
move lineageOS onto my device
install lineageOS
reboot
done.
This is the list of exact actions I am doing with no results is there something I am missing or something that is in the wrong order.

The exact problem I have is that I cant transfer any files to the device after formatting the data. I follow the steps correctly and I get into TWRP successfully and then everyone has told me to format the data then install lineage but I cant install the OS if formatting the data removes it.
Get device into fastboot
Flash revocery with TWRP
power the device off
hold volume up and power
boot into custom recovery
format data
move lineageOS onto my device
install lineageOS
reboot
done.

After format data, reboot your device into recovery again and transfer LOS, gapps and all files you need.
Format data kills the storage.

I always used to reboot from TWRP back in to TWRP after formatting data, but I've recently seen someone saying that they just unmount data then remount it again. I haven't tried it myself but it certainly makes sense and would be quicker too.

Yes I did that and it worked, unmounting and remounting helps detect the storage in PC

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 ?

Mic not working during calls - Mi 9

Hey everyone - long time lurker/researcher, but generally good at searching for answers without bugging anyone. This one has me stumped.
I have a Mi 9 CN model (6/128) that has been unable to make phone calls with the main mic without having to toggle Speakerphone on/off
I've tried 3 different custom roms (Xiaomi.eu, Pixel Experience, Evolution), and the Global MIUI 11 rom, but nothing seems to help fix it.
I have the newest version of TWRP installed right now (3.3.1-46), I have tried with and without Magisk installed....right now I don't even have TWRP installed at all on the Global rom.
Same happens for my SO's Mi 9 too as well.
Is there something I'm missing? I've tried turning off WiFi Calling/OK Google detection/VoLTE, rebooted, cleared cache/ cleared data inbetween new ROM installs....
Hardware test shows Main and Top as PASS.
Any tips would be appreciated! I feel like I've tried everything possible.
Thanks in advance~

Your TWRP is right.
Try to flash syberia with recommended vendor exactly step by step and of course really clean install with formatted data yes.
If this isn't working I'll think you've got to flash via pc the stock and then again a custom ROM.

I'm actually going to follow the Evolution instructions (just missed the part about flashing EEA)
So i'm using MiFlash with the MIUI11 EEA boot rom file, then I'll do the normal TWRP -> format data -> install Evolution ROM and test.
Thanks!

So it seems like I'm completely out of luck at this point - I've tried basically everything I can think of, and I think something big must be wrong with the phone's file system.
I've followed Evolution's steps to a T (minus MiFlash having an error at the end of the EEA flashing, but the firmware seeming to load fine) and still run into the no Mic issue.
"Flash MIUI11 eea with miflash
Flash vbmeta.img with "fastboot flash vbmeta vbmeta.img --disable-verity --disable-verification" (Download here)
Flash TWRP
Wipe (dont wipe system/vendor)
Format data
Reboot recovery
Flash rom
Reboot system"
Wipe (don't wipe system/vendor) I assume means just a normal factory reset wipe via TWRP, which I've tried.
I've tried both fw+vendor files (the newest for Android 10 and newest from Xiaomi.eu)
Any other last suggestions before I assumed the phone is broken?

Try to flash xiaomi.eu_multi_MI9_9.11.7_v11-10.zip
With miflash and after factory reset.
https://sourceforge.net/projects/xi...iaomi.eu_multi_MI9_9.11.7_v11-10.zip/download

SO! Update here
I was able to use Evolution X's Android 9 instructions to get everything working fine....but everytime I try to duplicate that for MIUI 11 it does not work.
Reboot to recovery
- Flash the latest 9.8.1 vendor image or full stock ROM.
- Reboot to twrp and format data
- Wipe cache/dalvik
- Reboot back to recovery and flash
I tested using the newest Xiaomi.EU Vendor for Android 10 and the stock one with no luck....more thoughts?

Did you try turning off the VoLTE?

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.
