[Q] Possible Bricked R800i

I very recently asked for help installing CM7 onto my phone. While following a fairly simple tutorial linked to me by the author something hasn't worked and I've been left with a brick. I managed to fastboot the boot.img then when rebooting I was asked to "spam" the volume button repeatedly until it entered another mode. It did not do this. Instead it simply left me with a blank screen. No Sony Ericsson logo and no booting into another mode as the tutorial described. Someone in the thread had the same issue and basically the author just washed his hands of it and asked that guy to make a thread. I did look at the troubled users profile for said thread but for some reason this forum is saying the search is down, so hopefully someone can help me at least get my phone working. I'm done with the rooting/romming shenanigans. If there is a way to just get my phone up and running then hopefully someone can tell me. Until then it's just a brick.
Edit - Tried updating via SEUS but it says the phone has modified software and cant be updated. :-(
Would flashtool work?? I have no idea how to use it tho but am downloading it. Looking for things on here is hard work. lol.

Is your boot loader unlocked? You didn't mention if it was or not. If its not then that's why your bricked.

Its unlocked. The tutorial before the one I mentioned above was about finding out if it was or not and it had a YES next to it in the menu. Along with my IMEI number etc, so I was told I was OK to go ahead with the other tutorial.

Flashtool Guide
Oh rght this should help you, okay. The answer to your question is yes flashtool should work, it sounds like you've got a botched install that's all if you doo this you should be fine
THIS WILL ERASE ALL DATA ON YOUR PHONE BUT NOT YOUR SD CARD
Here's a quick rundown of what you need to do, Download flashtool, download an ftf file, flash the ftf file to your phone through flashtool and then as if by magic your phone should work. So let's begin
Step 1) Turn your phone off - Then leave it to the side.
Step 2) Download and install Flashtool Get flashtool from here
After it has downloaded install it but make sure you have remembered the directory where you've installed it.
Step 3) Download an ftf file. This is a package that contains the stock software that came with your phone and flashing this will therefore return your phone to factory settings or stock.
Here is a thread with a list of ftf files, download the one that corresponds with your phone.
After you've downloaded it move it the folder named firmwares in your flashtool directory. For example mine is C:\Flashtool\firmwares
Step 4) Install the drivers. Navigate to the drivers folder in your flashtool directory, for example mine is C:\Flashtool\drivers From there open the file named Flashtool-drivers.exe and install ALL of the drivers.
Step 5) Flashing the FTF. Once you have installed all of the drivers open flashtool. From there click on the flash icon in the top left corner of the screen. Select Flashmode then click OK.
Select the FTF file you downloaded and moved to the firmwares folder and then click OK.
You will then see flashtool say it is preparing files for flashing follwed by a popup. The popup will promt you to power off your phone, hold the back button, then plug the USB into your Computer.
After you have done this flashtool will begin flashing your phone. Do not remove the USB until it is finished.
Once it has finished (The log will tell you when it has) remove the USB and power on your phone.
The initial boot may take some time as needs to rebuild it's cache. Don't panic this is normal. After it has your phone shoudl now have booted and be on the stock software that came with it
Hope I helped, if you need anymore help PM me

Thanks for the help but I was just too over that phone so I sent it away for cash (even fuc*ed it was worth £32) and I've got a brand new Xperia Arc S. Thanks.

Reinstalling OS after accidental delete

While attempting to install 6.0.1 on my SM-T705 I accidentally deleted the OS leaving me with the black screen of death (Samsung Tablet S logo and powered by Android). As I have only recently moved to Android and am still learning the ropes so any idiot-proof instructions to resurrect my tablet would be appreciated.
Thanks.
Glenn

Just flash the stock firmware with odin. Available at sammobile or youmobile.
Next time don't be silly and use TWRP to make that all important backup.

Here is how to flash firmware on your device:
1) Obtain the firmware. I find the most trustworthy place to DL it to be SamMobile. (You will need an account and it is a very slow download)
2) Download Odin3. It can be downloaded from here.
3) Download SAMSUNG_USB_Driver_for_Mobile_Phones.zip from here
4) Extract the zip and install the drivers
5) Power off your device. Once it is fully powered off, hold POWER+VOLUME DOWN+HOME until you reach the "Custom OS" screen. Once you reach this screen, press Volume Up.
6) Plug your device into your computer and extract the Odin zip. Now run the Odin EXE.
FOLLOW THE INSTRUCTIONS FROM THIS POINT ON VERY CAREFULLY
8) Extract the .tar.md5 from the firmware zip you downloaded from SamMobile earlier.
7) In Odin, select "AP" and select the .tar.md5. Odin will appear to hang, but give it a few minutes to finish processing the file.
8) Click "Start" in Odin.
9) Once the firmware download is complete, your device will reboot. It should work after this. If not, reboot back into Recovery mode to factory reset.

Thanks to you both for the help. I'm back up and running and the tablet has already been backed up with TWRP just in case I do something dumb like this again.

i notice thread title says exynos only.. u do know they are all exynos including a102u and a102u1 right?

Oh. Alright thanks for telling me.

Press on app? I have nothing in odin saying that, do you mean ap?
Edit: guess not....i'm bricked, stuck on galaxy logo, device not recognized by pc, holoding power button wont force reboot, nothing lol.
Edit2: can force reboot holding volume down and power but instantly stuck on logo again, cannot power off or enter download, nothing...bricked. Followed this guide to the letter. I assumed when you said app in odin you meant ap since there is no app button. My bootloader unlocked then I went to flash in odin the tar i made with patched boot and vbmeta, along with recovery linked. I used matching firmware to what my A10 has also. Would not mind if i could get back into download mode, but that looks impossible now.
Edit3: Managed to get download mode but had to be so quick...hopefully I can reflash stock now.

Im sorry for that and yes i meant AP.
If you wanted to reboot you had to hold vol up vol down and power at the same time and you sure that you unlocked the bootloader and used the right firmware?
Also tell me the AP and from which source have you downloaded it :laugh:

The corruption was my side, I was using a download manager, but when I downloaded through chrome it was all good. As I said, schoolboy error on my part for not checking md5. I used sammobile site for the firmware.

Need help rooting Samsung Galaxy A11 5F

Hello,
I am sorry if this is annoying in any way. I have spent the whole day trying to figure out how to root my Samsung Galaxy A11 and already wiped it twice.
There is not TWRP custom recovery available for it. To my understanding so far, I need TWRP if I want to install custom ROMs. I really do not care about installing custom ROMs. I have been trying to figure out how to root using the stock ROM.
Everywhere I look it says that I need to patch the stock ROM before flashing it by patching the boot.img file in the stock ROM download. I have downloaded several GBs of ROMs over a very slow connection and none of them has the boot.img file. I have the tar.md5 files (AP, BL, CP, CSC) but not boot.img. How do I proceed in this situation?
My phone model: SM-A115F/DS
Baseband version: A115FXXU1ATG1
Country: Egypt
Any help will be much appreciated.

https://forum.xda-developers.com/showpost.php?p=79106875&postcount=6
I downloaded a random J6 firmware in another site.
You have to use 7zip software, it's free, much better than WinRar and supports tons of compression formats. Do these steps with 7zip:
-Unpack zip file.
-Rename the "*.tar.md5" to "*.tar".
-Open the ".tar" file and unpack "boot.img.lz4".
-Unpack "boot.img.lz4" file.
-It's done, you now have the "boot.img" file you were looking for

Just one thing to point out, 7zip did not work properly to extract the boot.img from boot.img.lz4. I used the solution in this answer. https://superuser.com/a/1533657
Now, let's see if I can patch the boot.img

Hey there. I'm searchin' for TWRP for my A11 and no use.No one compile it and nobody can't write full f*****' guide how to build TWRP without any config file (or how to create 'em for building from 0). But honestly I'm not about TWRP.
Why do we need TWRP for Android 10!?
A: Samsung lock phones /system partition to Read-Only state. You can get root but you can't mount your partition as Read-Write, make changes in it. It's only waste of time.
How can I install ROOT for my samsung A**?
A: Very simple. I suggest you using Magisk Manager for it!
What do I need and what do I must do?
A:
1. You need unlock the bootloader of your phone (data will be lost).
2. You need original USB cable (from box of phone).
3. Yon need last firmware to your phone. (I'm using SamFirm or Frija)
4. Windows 7 or higher.
5. 7-Zip
6. Odin
How:
Stage I: Bootloader.
0. Remove all Google and Samsung Accounts
1. Make data backup (for recoverying)
2. Go to Settings -> Developer Options -> ADB Debug (set Enabled) (Search in web how to get Developer options Settings menu)
3. Go to Settings -> Developer Options -> OEM Unlock (set Enabled)
4. Turm off Phone and wait for 10 seconds.
5. Plug USB of Phone to your PC BUT PHON MYST BE UNPLUGGED!
6. Push and hold buttons: VOLUME UP and VOLUME DOWN and plug USB from PC to your Phone and still hold buttons!
7. When phon will be realy you'll see a light blue screen that ask you: Shall I unlock bootloader (Long press Volume UP), Shall I enter in download mode (short 'click' Volume Up) or I must turn off (Hold Volude Down)
8. Press and Hold VOLUME UP
9. On screen you'll se the message you'll unlock your bootloader... To hell Press POWER BUTTON.
10. Phone goes to reboot and start WIPING PROCESS!
11. That it. You unlocked bootloader. But will you install ROOT?
If so:
12. Make first setup of your phone but don't set google account and etc. Just make it working.
13. Go to Settings -> Developer Options -> ADB Debug (set Enabled)
14. Validate that's you've done everything right: Find OEM Unlock if toogle is gray and not responging to your actions then you've done right!
15. No download firware to your PC.
16. After you had downloaded firmware for your phone you'll fave few files you need file with prefix "AP_" open it with 7-Zip.
17. Get from it file: "boot.img.lz4" and put to some location at your PC.
18. Pack your "boot.img.lz4" with 7-Zip to "boot.img.lz4.tar" (YOU MUST USE *.TAR ARCHIVE TYPE)
19. Install Magisk Manager to your phone and put your archive "boot.img.lz4.tar" to location: Internal Memory/Download
20. Connect to WiFi and run Magisk Manager.
21. Make Kernel Patch with Magisk: Select: "Install Magisk" -> "Patch boot image" -> in file picker navigate and select "boot.img.lz4.tar"
22. (Magisk will do everything)
23. When it's done in folder "Internal Memory/Download" will be magisk_patched.tar copy it to your Windows.
24. (On PC) Run Odin as Administrator. And in tab "Options" unselect checkbox "Auto Reboot"
25. Turn off your phone and wait for 10 seconds, then Press and hold VOLUME UP and VOLUME DOWN and plug in your USB from PC to phone.
26. Phone will ask you what do need to do, just click VOLUME UP and you enter into Download mode
27. Odin must show you COM number.
28. Select as AP file "magisk_patched.tar" and press Start.
29. If you see PASS! in Odin - You've done! If ERR! then you failed to unlock the bootloader!
30. Now turn of fyour phone and enter into Recovery Mode (on turned off phone hold POWER + VOLUME UP)
30.a. If you failed to enter try in with ADB command: 'adb reboot recovery' (no quotes)

Installing Guide​In this guide, I will explain to you how and why we follow certain steps, so you can clearly understand every step, process, and risk of installing a custom ROM into a Redmi note 9. And avoid breaking your phone, bricking/hard bricking your phone: no operating system or a possible way to recover it, lost IMEI: can't make calls or receive.
In this guide, I will not explain to you how to unlock your bootloader! you can find plenty of guides online on how to do it and it's overall an easy job.
Before you start you will need to have an unlocked bootloader to be able to modify your system files. Once you have an unlocked phone you can start with the process of Flashing* a custom ROM.
The steps we have to follow are​--------------------------- Mandatory steps to be able to install a ROM, 1 - 7
1. Download Platform Tools*, A Custom Recovery*, and a modified VBMeta image, Mi-Flash to be able to downgrade MIUI, and the latest PixelPlusUI ROM which as of today is PixelPlusUI 3.9 for android 11 and PixelPlusUI 4.1 for Android 12.
2. Flash* recovery and VBMeta
3. Reboot into recovery
4. Backup IMEI
5. Downgrade your fastboot* into 12.0.3 version
6. Flash recovery and VBMeta
7. Reboot into recovery
--------------------------- Steps to install pretty much any ROM to Redmi Note 9, 8 - 11
8. Flash the latest firmware
9. Reboot into recovery
10. Wipe Dalvik/Art, Cache, Format Data
11. Flash PixelPlusUI ROM
---------------------------- Updating the ROM, 12 - 13
12. Update from 3.9 to 3.10.
13. Update to Android 12 with PixelPlusUI 4.1 (Optional) (Avoid for now cause it's unstable)
1. Once you have downloaded everything extract Platform Tools enter the folder where it contains all the necessary exes and run CMD inside this folder.
Turn off your phone, press the power and volume down button hold till your phone turns on, this will boot your phone into fastboot. Connect your phone via USB cable to your pc.
In CMD type "fastboot devices" without the annotations. it would output your phone right below with an ID and a fastboot label next to it.
if you are seeing "< waiting for device >" go to windows device manager, you'll find your phone in the other devices section with a yellow triangle. right-click it and click the first option to update the drivers, choose to select locally then Google => Android bootloader interface.
2. Now that we know fastboot is working and detecting our phone we have to flash the custom recovery.
copy the recovery file you downloaded, it should be an .img file, into the Platform Tools folder, in CMD now write "fastboot flash recovery recoveryname.img" without the annotations obviously, once its done, copy the vbmeta.img (might be named differently) also into the Platform Tools folder and write "fastboot --disable-verification flash vbmeta vbmeta.img" as vbmeta.img the file you just copied. if this throws an error do "fastboot flash vbmeta vbmeta.img" instead.
3-4. Now its time to backup our IMEI, if we don't back it up now, there's a change in the next step we lose access to make or receive phone calls, in case this happens we can flash back the IMEI and get it back to work. How do we back it up. While in fastboot, remove the usb cable, and turn off your phone, hold volume up and power till your phone turns on, wait till it boots into Recovery, if you accidentally boot normally into MIUI you will lose the recovery we installed before and it would roll back to stock xiaomi recovery, then you'll have to refollow step 2. Once in recovery, enter your pin and go to Tweaks, And tap the Imei backup, wait till its done, and then go back to the main menu, connect your phone via usb to your computer. your phone would pop up as a storage device, if nothing happens its because of the drives. go to windows device manager, you'll find your phone in the other devices section with a yellow triangle. right-click it and click the first option to update the drivers, choose to select locally then Google => Android ADB interface, Once it pop up enter into it and you'll find a folder called "imeibackup" copy that folder into your computer and keep it safe. this folder includes some partitions as img files and a zip file. the zip file is basically all the files archived into a single file, to be able to flash it later from recovery,
5. Time to downgrade your MIUI fastboot version, we have to do this, because if we don't downgrade we won't be able to install a custom ROM why? well, I actually down know, but pretty much flashing does nothing in the latest MIUI version 12.5 and so on, thankfully you can downgrade the MIUI version in the Redmi Note 9. The best version so far is the MIUI 12.0.3 and you only have to flash the fastboot image, The MIUI you gonna download has to be the same region as your phone e.g my phone is EU/Global i have to download the global fastboot image. if you miss-match them you won't be able to make or receive phone calls. Visit this page Visit this page find your regions "V12.0.3.0" MIUI version click on the very right "download" button, scroll down where it says "type:fastboot" bellow there a button "Download: Full ROM" the file ends with a tgz extension, extract the archive inside you'll find a folder named something like this "merlin_id_global_images_V12.0.3.0.QJOIDXM_20200807.0000.00_10.0_global" copy that folder into the root of your hard drive, rename it into merlin_id_global_images_V12.0.3.0.QJOIDXM
Install Mi-Flash, run Mi-Flash, click select and select the folder you copied into the root of your hard drive, on the bottom right corner flash_all_lock.bat change it into flash_all.bat this will prevent the bootloader from locking again, but it might destroy your IMEI partition, but thankfully we back it up in step 3-4. On your phone, while we left in recovery go to reboot => advanced => fastboot, once you are again in fastboot, connect your phone via a usb cable in to the computer in Mi-Flash press refresh, your phone will show up in the list, if not just follow again the drivers guide at the end of step 1. in Mi-Flash click flash next to refresh and wait till its done, the result should say success. Your phone will reboot and boot back to the old v12.0.3 MIUI version.
6-7-8-9. Now that we downgraded our phone is back to stock recovery and rom. we have to re-do some steps like installing the vbmeta and custom recovery.
Follow again the step 1 and 2. flash recovery and instead this time when flashing vbmeta.img just do "fastboot flash vbmeta vbmeta.img", reboot into recovery mode, by turning off your phone,
and then holding volume up and power till it turns on, now we are back into custom recovery we just installed again, in recovery now we have to flash the latest firmware of redmi note 9, this is necessary for PixelPlusUI to work properly. Download the latest firmware for your region from here, you'll get a zip file, copy the file zip into the platform-tools folder, open cmd in this folder and this time we have to sideload the zip via ADB. in your phone go to advance and then tap on sideload, tap the checkmark to start adb, on your pc in cmd you opened before type "adb devices" if it shows your device similarly as the fastboot devices step we did before you can continue if not, do the driver guide in step 3-4, once you ready type "adb sideload firmwarefilename.zip" replace firmwarefilename.zip with the firmware you downloaded name. once the sideload is done, click the X go to reboot=>advanced=>recovery, we have to avoid booting into miui now so we don't lose our custom recovery, this will reboot your back to recovery.
10-11. Now back in recovery go to wipe and tap the bottom right button Wipe with an arrow. when it's done, go to advanced and then sideload, click the checkmark,
copy the PixelPlusUI_3.9.zip into the platform-tools folder, in cmd you have open from before do "adb sideload pixelplusUI_3.9.zip" wait till its done sideloading.
once it's done, turn off your phone, and boot it normally, you will be greeted with the P logo of pixelplusui, set up your phone normally, if you see "no sim card please insert sim" its possible you flashed the wrong MIUI region or you lost your IMEI, you can flash the IMEI zip you backed up using the recovery's option of sideload or by using the flash option. if this does not fix it, redo all the steps but this time using mi-flash flash the right MIUI fastboot region and firmware region.
12. Updating PixelPlusUI from 3.9 to 3.10 which seems to be the last version before it got discontinued, in your phone, go to settings, system, update, download the update, once its done downloading, do not install it, close settings, hold the power button tap advanced => recovery, in recovery go to flash, go back in a directory and find the folder data/System Update, inside there you'll find a zip file called PixePlusUI_v3.10_something something.zip, flash that file without wiping anything, when it's done, go back and then go to wipe, tap advanced wipe, select only Dalvik/ART Cache and Cache so you don't lose any data. reboot, Done! Never update using OTA auto-update.
13. (For now avoid cause it's unstable) Time to Upgrade to Android 12 with the official build of PixelPlusUI version 4.1
Download the build, Using ADB sideload the latest official firmware, then reboot into recovery, format data and then install the ROM, you can copy it into the device or sideload it.
Every time you want to update or re-install a ROM (Any ROM) to your Redmi Note 9 you have to refollow the following steps:​1. Flash the latest firmware, Reboot to recovery after flashing.
2. Wipe Dalvik/Art, Cache, Format Data ( Don't do it if you just upgrade )
3. Install desired ROM.
Platform tools is a suite made by google for developers, it contains adb and fastboot apps which help you with installing/wiping content and doing more development related stuff to your phone.
VBMeta.img is required to be flashed to allow installing custom recoveries if you don't flash it, it would reverse the installed recovery back to the default Xiaomi recovery.
Custom Recovery a custom recovery is basically a separate OS that you can use to factory reset your phone when you can't access the main OS, or in this case, install random tweaks and mess around with system files and partitions.
Flash or Flashing Basically installing system files, partitions etc. can be done using adb, fastboot or from recovery.
Fastboot Similarly to Recovery is an option where you can restore your phone when you cannot do using the recovery, which is why we use it to install the custom recovery in the first place.
Tips for people who want to mess around with custom ROMs.
Every time you want to re-install a ROM, you'll have to re-install the firmware, the best bet is the latest Xiaomi firmware. Also, formating data is necessary to avoid bugs.
Known Bugs:​When the fingerprint sensor is touched it won't let you gesture swipe to close an app.
When the NFC is enabled there's a tapping sound on the microphone.

It would be easier to build a custom rom than installing it.

LMAO well, there's too much text to read. but it is totally worth it installing a custom ROM on redmi note 9

I see many people worried about that.
But I really prefer the stock MIUI, because it's so easier to me.
So, I can spend more time on xposed/lsposed and root/magisk.
Anyway, thank you very much for useful guide.
If somebody asks me again, I will send this guide

I've been developing games for android, and the redmi note 9 is my primary phone for it, because it is the middle ground of performance based on the average user. so as long the game runs well most people would be fine.
The thing is, MIUI with its ram management really makes me struggle, minimizing, and multitasking re-launches the game and System UI a lot of time freezes, nothing of those things ever happens with pixelplusUI, that's why I prefer it making me focus mostly on the GPU performance without getting bottlenecked by the heavy and nonoptimized os.

Well, well.
I understand you.
I confess that I've never played nothing at any android I've ever had, since my first android in 2014.
Really interesting to know about that.
I like the ram management because I don't have to close everything by myself.
My brother and my mother keeps everything on memory and management keeps to the system.
My brother has an iphone (sadly) and my mother has a Redmi Note 10.
I agree that the management by MIUI is excessive and should be more customizable.

Hello again, I'm considering to follow this guide.
Does this need no special setup? No SP Flash Tool? No bypass? Just flash in fastboot directly?
Considering the amount of EDL bypass tutorials out there it looks overly simple.
Can you confirm this works for Mediatek Redmi Note 9 without previous setup?
Thanks for the guide.

By the way, are we safe from ARP (Anti Rollback Protection)? I've seen both my current ROM and the target miui have an ARB version of 2 so it should be safe, but still I want to be sure.

Hello, i flashed miui 12.0.3 but it doesnt want to boot, stuck in bootloop, fortunately it boots into recovery, i wiped data and factory reset but it still doesnt want to boot, how do i fix it?

SOLVED: step 5 is faulty, you need to go to stock fastboot using vol - and power and not using the SHRP menu! i was trying to get it to work for 3 hours and i fund the solution, happy flashing!

Nothing faulty there you did not read the whole step. It says "downgrade using MI-Flash software", not using a custom recovery. Read the step properly and completely.

Yea it's safe I've downgraded from miui 12.5.5 to miui 12.0.1 and its totally safe. You can use miflash to downgrade

Edl bypass is only needed of you brick your device or it doesn't boot into fastboot or for taking backup kinda stuff.
Otherwise miflash does the job

thanks.

All works, thanks for the very detailed guide!
Quick question: do I have to flash with sideload or can I flash with SHRP?

I installed miui 12.0.1. will there be any difference if I use miui12.0.1 instead of 12.0.3?

I'm on miui12.0.1 and want to install pixel experience android 10 with shrp.
Do I need to flash the vendor if I don't want to install pixel experience via sideload and is it necessary to disable avb 2.0 after flashing vendor and custom rom?

I cant boot into the recovery mentioned in this step, what do I do?
“6-7-8-9. Now that we downgraded our phone is back to stock recovery and rom. we have to re-do some steps like installing the vbmeta and custom recovery.
Follow again the step 1 and 2. flash recovery and instead this time when flashing vbmeta.img just do “fastboot flash vbmeta vbmeta.img”, reboot into recovery mode, by turning off your phone,“

how long it take to flash redmi note 9? already 1000 seconds passed and its still flashing
