[REQ][A5 2015][SM-A500FU]Unbrick Image - Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot

Hi
I downgrade my Galaxy A5 2015 (SM A500FU) to 4.0.4 from 6.01, and now is hard bricked
Does not power on, can't enter to download mode, totally dead.
And now, I need a little help, I require some files from a working device (this is not unique files) but require to boot up the device.
I need a debrick image (First I try to unbrick with sdcard, and if this not working, I open the device and direct flash the emmc)
Requirements:
* rooted device
* 6.* firmware
* adb or terminal emulator
What I need?
Execute this command with adb, or terminal emulator, and upload the image to any filesharing site, or google drive, and send the link to me in private message.
dd if=/dev/block/mmcblk0 of=/sdcard/debrick.img bs=1M count=200
If I found a solution, how to unbrick this device in home, I share in this forum.
Thanks!

Did you manage to boot the unbrick image from SD card? I have the same problem, but as cannot communicate with the phone with adb, the card option seems to be the last one before sending the phone for some one with JTAG.

[SOLVED] Internal storage disappeared after unbricked

For unknown reason, my kindle fire bricked yesterday. After i unbricked it, i found myself unable to install any application.
I really doubt what i can do for my kindle. Please Help me, thank you.
create folder new with rootexploer and in adb write (file u-boot must be in folder tools of kfu:
adb push u-boot.bin /new
adb shell dd if=/new/u-boot.bin of=/dev/block/mmcblk0p2
and after flash other rom.
I had this problem after unbrick kf and only this method can help me.
Good luck

thanks for your help. i pushed u-boot.bin.
However, "dd: can't open '/new/u-boot.bin': Not a directory" shown after i enter the second command. So, what can i do next?
did you create folder? i had this error first time when folder was not created.

oh...i found the problem is that i only can use adb in recovery mode. But everytime i reboot it, all changes i made will be erased automatically due to the limited storage i think. So, i created the folder and it just being erased.
i know it.
1. Turn on device
2. Create a folder
3. Run adb
4. Write commands.
Must write a lot of text after the second command. So fff installed. If you reboot kf after this, can see yellow triangle.
thank you so much Deat7

[HOW-TO] Lenovo IdeaTab A1000 Rooting

HOW TO ROOT YOUR LENOVO IDEATAB A1000​
<DISCLAIMER>​
By attempting these steps, your warranty will be void. Even worse than that, it might cause crashes, freezes, random explosions, 2nd degree burns, or even turn your beloved tab into $100+ paperweight. What works on mine might not work on yours, so don't attempt if you don't know what you're doing. Do at your own risk. Corrections are welcome. I must admit that I'm not an expert, so any info I posted might be wrong, and I can't offer you much help. I'm not responsible for anything arising from the use of this how-to. I can only wish you good luck.
<WHY ROOT?>​
- Without root or OTA upgrades (at time of writing, Indonesian customers still can't get it), you'll be stuck with ~500MB internal memory. That's annoying.
- You're stuck with the default IO scheduler (cfq) and governor (hybrid, haven't heard that one..)
- You have an incredibly large amount of bloatware you can't get rid of, in that already cramped up internal storage
- Did I mention freedom?
<REQUIREMENTS>​
This method is originally used to root Acer Iconia B1-A71. Somehow I noticed that the two actually has the same chipset, MTK8317 (if it really was relevant ). So I tried the method, and through sheer n00b's luck, it worked like a charm!
Lenovo IdeaPad A1000-G --> 4GB storage, 2G/EDGE. This method haven't been tested on A1000-T/F, different storage cap (16GB, etc.) or other variants, but it should work with slight modification. Screenshots of my specs are attached below. Remember, proceed at your own risk!
A Linux System. Never tried on Windows or Mac. I personally used Linux Mint 15. The source post uses Ubuntu.
working ADB (android-tools-adb). You can get this from synaptics, apt-get, etc. If your system can detect adb devices, you should be fine.
Superuser Binary
Busybox Binary (You can get these two from the links on original post. XDA says noobs can't post links :'( )
ORIGINAL THREAD
<CREDITS>​
XDA Senior Member entonjackson, for writing such a noob-friendly how-to for rooting Acer Iconia B1-A71 and for allowing me to use it for this how-to.
XDA Member alba81, for discovering the method as acknowledged on the original post by entonjackson
All awesome gurus on XDA which I can't mention one by one.
<THE STEPS>​
1. Extract the android sdk to your home folder, e.g. a user named Bob will use like /home/bob
2. Open a terminal
3. Now plug your A1000 into your machine and turn on Debugging Mode (Go into Settings -> Developer Tools, turn on Developer tools, then turn on USB Debugging Mode)
4. Now back at the keyboard of your Linux machine in your terminal type:
Code:
sudo adb devices
The output should be something like:
Code:
123456789ABCDEF device
If it's not, google for it. Somehow your Linux hasn't detected the A1000, although the android sdk for Linux brings all needed drivers with it.
If your device was found, congratulations. The adb connection between your linux machine and your tablet is intact.
5. Now extract the downloaded busybox archive to your home folder, in it there should be a busybox binary. So Bob does:
Code:
sudo ./adb push /home/bob/busybox /data/local/tmp
Code:
sudo ./adb shell
Code:
chmod 755 /data/local/tmp/busybox
6. You should copy the busybox binary into a directory where you can access it as a plain non-root user on the tablet. We need this binary. so we can apply unix tools like telnet, dd, cat, etc. But for now we need it to establish a telnet session between our tablet and our linux machine.
(This point is written on original post. Seems important, but as soon as I finished step 5, I can use those tools)
7. Dial *#*#3646633#*#* to enter Engineer Mode
8. Go to Connectivity -> CDS Information -> Network Utility
9. type the following command:
Code:
/data/local/tmp/busybox telnetd -l /system/bin/sh -p 1234
Advice from original poster: copy and paste it from the browser on your tablet, because dependent on which keyboard app installed, this can be freakin tricky. In the next step you will learn, why it's so important why this command should be correct.
10. Tap on Run. You won't get any feedback, so you will never know if the entered command runs properly or not. That's why you should make sure the command is ok.
Now we have started our telnet server on the tablet.
11. Back in the terminal type:
Code:
/data/local/tmp/busybox telnet 127.0.0.1 1234
If you now get an error like couldn't find busybox or something, then either adb push failed or you forgot to chmod, in step 5
12. Now enter:
Code:
cat /proc/dumchar_info
You should get a bunch of lines, try to find a line containing the partition named android
{..... partition list .....}
android 0x0000000028A00000 0x00000000020E8000 2 /dev/block/mmcblk0p3
{..... partition list .....}
13. We will create a dump of our android system. This is the point where different variants *MIGHT* have different parameters. This step is important, as wrong parameter will result in unmountable image.
Stop. Take a deep breath. If you're not familiar with dd, find a good doc of it. There's a plethora of them.
Get yourself a programmer's calculator (Linux Mint 15 has one built in).
Here's what you'll do :
Convert the hex number on the 3rd column into decimal. In my case (0x20E8000) will yield 34504704. Divide by 4096. The result (8424) goes to the skip parameter.
Convert the hex number on the 2nd column. In my case (0x28A00000) will yield 681574400. Divide by 4096. The result (166400) goes to the count parameter.
So the full dd command will look like :
Code:
dd if=/dev/block/mmcblk0 bs=4096 skip=8424 count=166400 | gzip > /cache/system.img.gz
Do a full sanity check before hitting enter! It will take about 5 minutes.
14. After it's finished we must make the image readable for adb, so we do:
Code:
chmod 777 /cache
and
Code:
chmod 777 /cache/system.img.gz
15. Leave the telnet, and then adb shell session by:
Code:
exit
Code:
exit
16. Now we pull our image by
Code:
sudo adb pull /cache/system.img.gz
wait 1-2 minutes.
It should be then located inside /home/bob. It did for me. If not, do a search . It should be a .gz, extract it right there (or /home/bob if it isn't there)
17. Now we need to modify our system image by adding the tiny but helpful su binary. Extract the SU binary to /home/bob.
18. We create a folder where we will mount our system image to. To create it do:
Code:
sudo mkdir /media/a1000
19. Now we mount it:
Code:
sudo mount -o loop /home/bob/system.img /media/a1000
if it fails, then you entered wrong parameters on step 13
20. Now we copy our SU binary to our mounted system image:
Code:
sudo cp /home/bob/su /media/a1000/bin
21. the su binary needs to have the proper rights to make it usable, so we 'suid' it with:
Code:
sudo chmod 06755 /media/a1000/bin/su
22. Let's unmount our baby by:
Code:
sudo umount /media/a1000
and because bob doesn't like a messed up system, he does:
Code:
sudo rm -rf /media/a1000
because he hopefully won't need it anymore.
23. We have to gzip it again to bring it back to where it belongs to. this we do by:
Code:
cd /home/bob
Code:
gzip /home/bob/system.img
24. So here we are now, we made it to the final Boss fight! The next steps are dangerous and should be performed with caution. We copy back our modified system image, which can brick your device, if you do a mistake! Enter adb shell again :
Code:
sudo adb shell
25. Remove the old boring image:
Code:
rm /cache/system.img.gz
26. Leave adb shell
Code:
exit
27. copy our cool new system image containing the su binary:
Code:
sudo adb push /home/bob/system.img.gz /cache
28. Enter adb shell again
Code:
sudo adb shell
29. Usually the telnet server on the tablet is still running, at least in my case it's been like that. That's why we can directly connect to the telnet server with:
Code:
/data/local/tmp/busybox telnet 127.0.0.1 1234
If this doesn't work, then obviously your telnet server isn't running anymore. So on your tablet if the telnet command is still entered (see step 9), tap on Run again and repeat step 29.
30. Now this is the most dangerous step in this how to (no it wasn't the mkdir one). You can copy following command to make sure everything is fine and paste it into your telnet session on your linux terminal.
<WARNING! SANITY CHECK! MAKE SURE *ALL* THE DD PARAMETERS MATCH THE FIRST DD (STEP 13) OR YOUR A1000 WILL TURN INTO A VERY EXPENSIVE PAPERWEIGHT!>
Code:
[B]/data/local/tmp/busybox zcat /cache/system.img.gz | dd of=/dev/block/mmcblk0 bs=4096 seek=8424 count=166400[/B]
After 1-2 minutes you're done, if your tablet or pc or yourself didn't catch fire, everything's fine.
31. Leave telnet / adb shell by doing
Code:
exit
Code:
exit
32. Reboot your A1000 via ADB, then exit
Code:
sudo adb reboot
Code:
exit
33. Unplug your tablet from PC
34. Install Superuser (No, not SuperSU, cause it won't work!). I personally use Superuser by ChainsDD, from Play Store
35. Be lucky. Your tablet and thus you are now free!

have you chmod-ed the busybox (or is the chmod successful without error)? Try chmod-ing the /cache before attempting step 13. It seems that you still don't have access to the NAND device (mmcblk0). Have you updated firmware via OTA?

I'm not sure whether the stock kernel of our devices supports init.d, thus supports CronMod/Data2SD. Lenovo locked our bootloader, and currently there's no way around it. So I personally think, Link2SD method are the best option for now.

Hi, Can any one upload Lenovo ideatab A1000 system.img
in step 20, it appears you are writing to a /bin directory on the android system. However such a directory is not visible either through shell or the system telnet account.

Actually the SoC is MT8317. For some god-knows reason Mediatek have made this SoC with signatures similar to MT6577. But somehow CPU tweaker correctly detects the SoC (MT8317). Maybe it's the CPU-Z bug?

Connect your phone to adb in recovery mode, then type
Code:
adb devices
Your phones id should show.
Code:
adb shell
If you get ~# and something, then type
Code:
dd if=/dev/block/mmcblk0p5 of=/external_sd/aboot.img
It will save a copy to your external sd card.

[Guide] OnePlus 8T EASY ROOT (for all unlocked variants)

DO NOT FOLLOW THIS GUIDE IF YOU HAVE ANDROID 12
Visit this thread for more information
________________________________________________________
CAVEAT
I've only tested this on my device running Android 11 (KB2005 / KB05AA), but it should be universally helpful as it's using your own boot.img so there's no need to find a matching package for your variant and os version.
CREDIT
The steps were buried across a few threads, I'm posting this so it'll be easier for others to find the information. All credit goes to xb360, FullOfHell, and TheUnkn0wn.
INFO​The basic rundown is:
Use the semi-broken TWRP package to give yourself temporary su access through adb.
Extract the boot.img your phone is currently using to your pc.
Reboot to OxygenOS, copy over the boot.img you just extracted and then use Magisk to patch it.
Copy the boot.img back to your pc and use adb to temporarily boot your phone with it, giving you root access until reboot.
Use your temporary root access to allow Magisk to patch your internal as-yet unmodified boot.img to give you permanent root.
There seems to be some confusion in the thread, I'll try to clear up what's happening and why:
The primary issue at hand is that you can't root your device without already having root privileges, for security reasons. Without a custom recovery like TWRP, there are a few more steps than usual (but mostly simple stuff).​
Because we don't flash anything with this guide, it shouldn't cause any permanent bootloops if you use the wrong boot.img, if you get stuck in one just power cycle your phone. ​
Updating with OTAs should be the same process as the other guides here.​
Because of changes in Android, devices that launched with Android 10 and above will not allow you to modify the system partition, even with root. This is not a fault of this rooting method.​
Prerequisites:
ADB and Fastboot installed.​
An unlocked bootloader and USB debugging enabled.​
Android 11. (Android 12 introduced problems with this method, per other users. See link at top of page)​
________________________________________________________
STEPS:​
1. Connect your phone to your pc and boot it into fastboot mode. You can leave it connected throughout this guide.
2. On your computer open a terminal/cmd prompt. Set the directory (on your pc) you want to work from, I'm using the desktop:
for Windows, type cd C:\Users\Yourname\Desktop​for Mac, type cd desktop or cd /Users/yourname/Desktop​
Spoiler: How to set up adb and fastboot properly
To usb adb and fastboot commands outside of the folder those programs are located in, you'll need to add their location to the PATH list so your terminal can still find them when it's pointing to a different folder. If you want to skip this step, set the directory to the folder that contains adb instead of the desktop.
3. Next, use the terminal to check which A/B partition is active on your phone:
Code:
fastboot getvar all
a. You'll find it on this line: (bootloader) current-slot:a/b​b. For simplicity I'll be referring to boot_a.img throughout the guide, make sure to use boot_b.img if that's the one marked as active on your device. ​​
4. Download the semi-broken TWRP package to your desktop. We'll be using it to extract a copy of your active boot_a.img. It will give you temporary su access via adb, but there won't be a gui. Only boot from it, DO NOT FLASH IT:
Code:
fastboot boot recovery.img
adb shell
dd if=/dev/block/by-name/boot_a of=/sdcard/boot_a.img
exit
adb pull /sdcard/boot_a.img boot_a.img
adb reboot
5. Copy the extracted boot_a.img file to a user accessible area of your phone, like your downloads folder.
6. Install the latest Magisk Canary apk on your phone. Open it and:
a. Select the Install option.​b. Use Select and Patch a File on boot_a.img​
7. Copy the patched magisk_patched_a.img file back to your computer. In terminal, type adb reboot bootloader to get back to fastboot mode.
8. Temporarily boot with the patched image that corresponds to the active partition, DO NOT FLASH IT:
Code:
fastboot boot magisk_patched_a.img
Spoiler: Why we're booting and not flashing.
You could flash this boot.img, but it's safer to temporarily boot from it without overwriting your existing image in case anything went wrong along the way. The effect is that you still get root access without modifying your device, and then you can use the much safer Magisk direct install option, which has some safeguards in place.
9. By booting with the patched image, you now have temporary root access. To make it permanent open Magisk:
a. Select the Install option.​b. Use Direct Install (Recommended) to root your internal boot.img​
10. Reboot and verify it worked.
Forgot to tag it... if an admin is able to do so I'd appreciate it.
Just applied for a bootloader unlock today. When i get approved ill attempt this guide.
I am currently on T-Mobile 11.0.5.7.KB09CB.
Unlike other methods prvoided here for the 8T I got this method to work. Thank you very much!
clarification update: I own the t-mobile kb2007 model of phone
a couple of notes for any either newBs or old OPO users rejoining the party with a new onplus phone..
Some prework I had to do for my OnePlus 8T KB2005
-ensure you have the correct ADB driver installed, I installed the "15sec adb installer 1.4.2" found here on xda, watch the videos provided.
-ensure to unlock your bootloader first (*this will wipe your device.. didn't think about that..no pain no gain...)
-With device in bootloader/fastboot, run: fastboot flashing unlock
-verify with your phone to accept
-phone will reboot, just through the setup, I just skipped it all and opted for offline setup..
-renable OEM lock and USB debug
-restart back into bootloader/fastboot
-now you are ready to root
Just came here to say that this is the most genius way to go about it and thanks OP for this solution. To add your screen would flicker in TWRP but you just want to type adb reboot bootloader after you are done copying off the boot files from your phone. Thanks OP!
After performing this, I am unable to write to /system even with root?
Unable to get through with es explorer, root explorer pro, or even use a app like Titanium to move a user app to system,unable to get r/w access.
Thanks in advance

To be clear, you're saying this isn't a fault with this root method and is just a security measure since Android 10?

CAVEAT
I've only tested this on my device (KB2005 / KB05AA), but it should be universally helpful as it's using your own boot.img so there's no need to find a matching package for your variant.
CREDIT
The steps were buried across a few threads, I'm posting this so it'll be easier for others to find the information. All credit goes to xb360, FullOfHell, and TheUnkn0wn.
INFO​The basic rundown is:
Use the semi-broken TWRP package to give temporary su access through adb.​
Extract boot_a.img and boot_b.img to your computer.​
Reboot into OxygenOS and copy boot_a.img and boot_b.img back to your phone.​
Use Magisk to patch both images.​
Copy the patched images back to your computer.​
Use fastboot to temporarily boot using the patched image, giving you temporary root.​
Use Magisk to direct install for permanent root.​
Prerequisites:
ADB and Fastboot installed.​
An unlocked bootloader and USB debugging enabled.​
________________________________________________________
STEPS:​
1. Get the semi-broken TWRP .img. This won't give you a gui but will give you su access over adb. You DON'T want to flash this, we're just booting with it temporarily.
2. Restart your phone into fastboot mode.
3. On your computer open a terminal/cmd prompt and set the directory where you want to dump the files (ex: cd /your/path/here). Run the following:
Code:
fastboot boot recovery.img
adb shell
dd if=/dev/block/by-name/boot_a of=/sdcard/boot_a.img
dd if=/dev/block/by-name/boot_b of=/sdcard/boot_b.img
exit
adb pull /sdcard/boot_a.img boot_a.img
adb pull /sdcard/boot_b.img boot_b.img
4. Copy the extracted files to a user accessible area of your phone.
5. Install the latest Magisk Canary release to your phone.
a. Select the Install option.​b. Use Select and Patch a File on both boot_a.img and boot_b.img​c. You should rename them or make note of the new names given by Magisk. You'll need to use one or the other depending on which partition is active. ​
6. Copy the patched .img files back to your computer.
7. Restart your phone back into fastboot mode.
8. On your computer, run:
Code:
fastboot getvar all
9. Find which A/B partition is active on this line: (bootloader) current-slot:a/b
10. Temporarily boot with the patched image that corresponds to the active partition, DO NOT FLASH IT:
Code:
fastboot boot patched-boot-a/b.img
11. You now have temporary root access, to make it permanent open Magisk:
a. Select the Install option.​b. Use Direct Install (Recommended) to root your internal boot.img​
12. Reboot and verify it worked.

hey there! I was just about to try this method but confused with this syntax -- don't mind the quotes
"On your computer open a terminal/cmd prompt and set the directory where you want to dump the files (ex: cd /your/path/here)"
I'm painfully confused about this: cd /your/path/here. is this done during fastboot? I know fastboot commands but adb is where my brain doesn't get it. Please elaborate further and thanks.

When you open a terminal or command prompt on your computer it is, by default, 'pointing' to a certain folder. Since we're pulling files from the phone to pc it'll dump there, so it's easiest to set the location in advance, for your own convenience. You can just make a folder on your desktop and drag it onto the terminal window to automatically input that path after typing cd, which just means 'change directory'. This isn't a fastboot or adb thing, just a feature of terminals, so you'd do this in advance.

Attached are 2 photos -- the 1st photo is the "before" I dragged my intended folder into command prompt. the 2nd photo is the "after" I dragged my intended folder into command prompt. Still hella confused.
Please note: I love this guide. It's cohesive and well-written. I just need pictures to "see" on what and where to do. I'm visual.
UPDATE: I followed the tuturial to the best of my ability and I got nothing. I'm giving up and taking a step back.

You're missing the command "cd" before the path to change the directory to the new one. It should be cd C:\Users\Mr. Lew\Desktop\oneplus 8t boot image then press enter. Now you can reference any file in that folder by just the name without its entire path as a prefix being required.
A difficult method

huh?
Honestly, if there's a kind of soul out there who can share their unpatched kb2007 boot image (tmobile version), I would greatly appreciate it. I'm been banging my head on the wall with this for about 2 months with no help. I've received TONS of half-baked one liner answers but no "full-scale" tutorial. I'm giving up on this.
NOTE: I'm just frustrated guys. Not bashing the OP. It shouldn't be this hard but it became this way.

While this is a temporary solution, it is also a bad solution because you can land with not being able to boot your phone every time an incremental update comes along.
