How downgrade lg software?
I´ve seen this in this spanish forum (https://forocoches.com/foro/showthread.php?t=8935750)
Translated to english:
IMPORTANT: Check the updates from the HOMEBREW CHANNEL itself.
If you have the TV connected to the internet...probably you have been updated to a non-vulnerable version. It is necessary to perform a downgrade.
2- DOWNGRADE - If your TV is not functional the link above.
With WebOS 1.x - 5.x
To do this, you download the firmware of your TV from this Telegram Group.
https://t.me/lgwebosusb
With the firmware loaded in a USB FAT32 we put it in the TV and go to this web.
https://webosapp.club/downgrade/ and it will install the firmware.
Quote:
WebOS 1.x - 5.x
1. Download the firmware file for your device to update via USB (attention! USB firmware file type is required, not nsu).
2. Format the USB flash drive to FAT32 file system, create LG_DTV folder, unzip the .epk file from the previously downloaded archive

Rolling back and restoring previous firmware versions on LG TV sets.
Rolling back the firmware using a special application (webOS 4+)
A new easy method to rollback to an older version of the firmware.
What is firmware?
Firmware is the operating system of your TV that controls all of its basic functions. Since 2014, LG TVs (and since 2017, Bang & Olufsen OLED TVs) have been running on the webOS operating system, which is the basis of all firmware for them. Officially online, you can only update to the latest firmware.
What kind of changes can I make to the TV software with the suggested way?
TV firmware is not final and unchangeable software and can be subjected to the following changes:
Upgrade - installing the firmware by upgrading to the current version;
Reinstall - re-installing the identical version of the firmware over the current one (sometimes helps in situations instead of resetting to factory settings);
Rollback (restore) the firmware (downgrade webOS) - installation of the old version of the firmware, which is officially no longer up to date on the server LG. Restoring the TV firmware is used when you need to correct errors in its operation, to lower the version of the firmware (to make a downgrade) or to install custom (not yet available) firmware.
On which TV models are firmware changes supported by the suggested way?
The suggested way works on most of LG TV models of 2012-2020 with network support. Required to rollback or to install the firmware files are grouped in appropriate subfolders in the folder "zagotovki", depending on the model of your TV.
On 2014-2016 TV models with the latest firmware from 2018 and later, the ability to rollback to past software versions was blocked, there is a solution (link at the end of this post).
On TV models of 2017-2020 year the possibility of rollback is blocked in the original (factory) firmware, at the moment on TV models of 2017-2018 year you can install only files of new software versions, which are designed to update online via the network (current software version number in TV must be less than the number of installed software version) using the offered method. On 2019-2020 TV models, installation of new online firmware is not yet available via rollback method. To avoid problems with rollback after automatic installation of new firmware online, you need to immediately disable the item Automatic update in the TV settings and in the future to update only to the verified software versions.
Detailed information about the model names and the corresponding file names of the answers in a spoiler.

What are the options for the suggested method?
There are two options: local method (downloading firmware files from your computer) and online method (downloading firmware files online from LG update server).
How to correctly roll back (restore) a previous firmware version or install a new firmware version?
Download LgDTVUpDater_04_2022.zip archive file with the set of firmware rollback (updated on 02.04.2022).
Unzip the archive file contents to the root of C:\ drive, LgDTVUpDater folder should appear. If somebody needs to install (extract) archive content to the root of another drive (D:\, E:\, F:\) but not to the root of C:\, then after unpacking replace all the content ("LgDTVUpDater\apache\conf\httpd.conf") from the additional archive file httpd.zip from the folder (D, E, F) corresponding to the drive name with confirmation of data replacement from the already installed folder LgDTVUpDater. This replacement can also be used to unpack the contents of the archive to a flash drive, if there is no additional partition and there is only the system partition, then all the data should run from the flash drive. If you downloaded the previous version of the archive from here and configured the program, be sure to delete the old zagotovki folder from the installed LgDTVUpDater folder and copy the new zagotovki folder with the updated data from the new archive.
At the end of file "LgDTVUpDater\dns\AcrylicHosts.txt" manually change all addresses like 192.168.0.11 to the local IP address of your computer. The server names snu.lge.com, lgtvonline.lge.com, su.lge.com and su-ssl.lge.com to the right of the IP addresses should not be changed. If using the local method of downloading firmware from a PC, remove this # in front of the last three lines with the addresses lgtvonline.lge.com, su.lge.com and su-ssl.lge.com, otherwise default settings to download firmware over the network from the LG update server. Perform this manual data change only when manually running these two files (startDNS.bat and startHTTP.bat), ignore this instruction point when using start.bat or start_new.bat.
Note: For the IP address of your PC, see here: Control Panel - Network and Sharing Center - via Change Adapter Settings select your connection and right click on Status and then under Information find the line IPv4 Address. Or press the Win+R key combination on your keyboard, and in the window that opens type "cmd" (without the quotes) and press Enter. At the running Command Prompt, type: "ipconfig" (without the quotes) and press Enter. Next, find the line IPv4 address of your computer, consisting of a set of numbers in the format xxx.xxx.xxx.xxx.xxx (e.g. 192.168.1.2). This is the local IP address of your PC.
Now the most important, go to any folder "LgDTVUpDater\zagotovki\online\" or "LgDTVUpDater\zagotovki\local\" when setting for local PC software download method, and when setting for LG server software download method, only go to "LgDTVUpDater\zagotovki\online\" folder. Open the folder with your TV model, there are folders containing answer files for different versions of early and current firmware. The name of the folder shows the software version with country codes that you need to select. If the name has a _ at the end, it means this version was in test access at the date of creation. Select the answer file of the software version you need from the appropriate folder and copy it to the folder "LgDTVUpDater\htdocs\", agreeing to replace the original file if it was already there.
Note: When downloading the software file locally from your PC, copy the appropriate software file into "LgDTVUpDater\htdocs\" folder by downloading it from the appropriate forum threads or here. The size and name of the software file itself must correspond exactly to the data that is listed inside the contents of the corresponding answer file. Pay attention to the end of the firmware file you have downloaded. If there are signs like this before the extension (.epk) after SECURED at the end of the software file, this must be corrected to the corresponding [0] or other similar signs ([1], [2], [3]) that are written inside the contents of the answer file. In this case the software file will be downloaded to the TV from your PC and not from LG's update server.
Run manually startDNS.bat from the root of the LgDTVUpDater folder to load the DNS server and do not close the command line window (you can only minimize it). There will be several lines in this window, they will be added in the process of updating. Run manually startHTTP.bat from the root folder of LgDTVUpDater to load the web-server, also do not close this window (you can only minimize it), there must be only one short line in the window. With these actions you have manually started the applications on the PC to perform the firmware installation.
Note: Instead of starting these two files manually, you can run the file start.bat from the root of the folder LgDTVUpDater, and perform all the actions suggested there to enter the IP address and select the method in the dialog mode. You can also try another alternative variant of the DNS-server DualServer, confirming its start via start_new.bat and performing the same actions as for start.bat, the applications will be started automatically. If you have already started these files and there is no need to change the PC IP address in the settings file and select another method, you can skip all the actions at the beginning of the dialog indicating Y, then the two applications will be launched with the same data. When using the alternative DualServer DNS by starting_new.bat, you must manually set all network settings on the adapter (IP address, mask, gateway and DNS addresses) before running the application. This condition on the PC is also desirable to use a different DNS server. When running these files in dialog mode, skip the 3rd point of the manual data change to the local IP address of the PC.
In the TV set, which should be in one local network with the PC via a router, select the manual mode in the network settings and change only the data in the DNS field - to the local IP address of the PC where you run this set of applications (how to find the IP address of the PC is described above in p. 3). Next, confirm the network startup by executing Connect. If something in TV does not work with network settings, then try to disable firewall on PC or something that prevents TV to connect to network through PC and router, like blocking port 80, for example Antivirus, Skype on PC and all its processes must be closed.
Everything is ready, you can check the update on the TV by selecting the item in the appropriate TV settings to update the software and when the message that the desired version of your choice is available, run the update as usual, and watch there in the settings process of downloading the software file. Do not change the service country in the TV and leave it as it is, regardless of the software categories.
After updating return the TV network settings to the original DNS address or set it to automatic, then restart the TV to finish the update.
On the PC, close the two open windows (close running applications). That's it, the installation of the firmware is completed.
Note: In the root of folder LgDTVUpDater you will find a file with detailed instructions how to use this method on LG TV models of 2012-2020. Please read it carefully in case you have any problems with the software.
What is the difference of the local method of downloading software from a PC and the network method of downloading software from LG update server?
The local method of installing firmware over the network between your PC and TV without a router and without the internet
Then there is only one way left, which is to exclude the influence of the router with the settings from your ISP and the Internet itself on this whole process, and to connect the laptop (PC) and TV only with twisted pair network wire between each other to perform a pure local method of installing the software. The wire should be crimped as to connect two PCs, not as to connect through a router. Then you have to configure the network adapters on the laptop and on the TV manually. For example respectively on the laptop IP address - 192.168.1.2, the mask - 255.255.255.0, gateway - 192.168.1.3, DNS address - 192.168.1.2 and in the TV settings the IP address - 192. 168.1.3, the mask - 255.255.255.0, gateway - 192.168.1.2, DNS address - 192.168.1.2. Previously, do not forget to copy the file with the corresponding software version to the folder htdocs of the program and replace the file with this version from the folder zagotovki\local. Then on the laptop (PC) run start.bat or start_new.bat, successively answering (N, Y, Y, Enter), and on the TV in the network settings with the prescribed above data press connect. If the network access is successful (all 4 icons must be green), check the availability of the software version in the TV settings, if everything corresponds, then update. Note that the name of the software file must be exactly the same as in the answer file for the corresponding software version you have selected.

Possibility to rollback to previous software versions for TV models of 2014-2016
http://webos-forums.ru/post23656.html#p23656 (russian language and a lot of firmwares)
Alternate option of rollback firmware versions with rooted rights feature
A new easy method to roll back to an old version of the firmware for televisions with webOS 4.0-6.0 (for webOS 3.0 use the below method):
1) The first thing to do is to get a USB version of the old firmware for your TV using https://web.archive.org/. Copy this address into your browser "https://web.archive.org/web/*/https://www.lg.com/ru/support/product/lg-xxxxxx" (without the quotes). Then replace lg-xxxxxxx with the name from the official LG web site https://www.lg.com/ru/televisions (for example, for 49UM7490 it will be "https://www.lg.com/ru/televisions/lg-49UM7490PLC" and the address to get the old firmware will be "https://web.archive.org/web/*/https://www.lg.com/ru/support/product/lg-49UM7490PLC" - the last rooted version was on May 2nd at 09:38:57). Go to this address and download one of the previous firmware versions.
The alternative USB firmware repository for TV with webOS 4.0-6.0 on Telegram is https://t.me/lgwebosusb.
3) Unzip and copy your firmware onto FAT32 formatted flash drive to LG_DTV folder (for example E:\LG_DTV\starfish-dvb-secured-k5lp-539.gyeryongsan.k5lp-53904-05.00.15_prodkey_usb_V3_SECURED.epk),
4) Insert the flash drive into the TV, go to https://webosapp.club/downgrade through the TV browser.
5) The TV will load the firmware and prompt to reboot, after the reboot it will install the "new" firmware.
In the above case (for 49UM7490) it is version 05.00.15, which allows you to get root.
Good luck everyone. Write here about the results of using the new method!
Firmware rollback using special application (webOS 4+)
The method described here Rollback and Restore Previous Firmware Versions is primarily intended for use on webOS 4.x-6.x to return to a rooted software version.
On earlier versions (below 3.x) the method may not work, in particular at point 4 with a browser will not run the regular update application.
Made an application that runs the regular update application with the right parameter. It should be put in developer mode and run instead of the link in the browser in step 4 of the original instructions.
All other items are relevant. Application is downgrade.launch.app_1.0.0_all.ipk

Hello. I installed the latest Android-IA (android-4.2.2_r1-ia1) on my Acer Iconia W700, and it works perfectly. The only downside (however, huge one) is the lack of libhoudini - without it half of android apps refuse to load on x86 processor. Which, by the way, scores ~70000 in Antutu (!)... I searched everywhere, but there's just too little information on both libhoudini as well as Android-IA . Please, can anyone help in porting this library to Android-IA? I know it is not open source, but so are gapps, and Android-x86 already uses libhoudini. So there shouldn't be any real difficulties... WBR, Draco.

I searched everywhere, but there's just too little information on both libhoudini as well as Android-IA . Please, can anyone help in porting this library to Android-IA? I know it is not open source, but so are gapps, and Android-x86 already uses libhoudini. So there shouldn't be any real difficulties... WBR, Draco. Click to expand...

Hence the only solution would be to switch to android x86...
Change dpi and get bluetooth working with android and windows 8.1 at the same time Do these changes if you are confident in your skills. I'm student and quite busy so if you ask something it can take some time for me to answer. Damages you might do to your system are your own responsibility. I have tested these instructions with Acer W700 on android-4.2.2_r1-ia3 and can confirm that they worked for me. First changing dpi from original 213 to 160: 1. Get file manager on android like ES file Explorer 2. R/W rights to whole system on android 3. From root go to /system/etc/machine-props/ 4. Open acer-w700.prop with ES Explorer and edit line "ro.sf.lcd_density = 213" and change 213 to 160 5. Reboot android and system should now be 160 dpi Now about that bluetooth. I find it annoying that you have to pair your bluetooth mouse and keyboard again every time when you switch between android and windows 8.1. So I did research and found a way to fix this problem and here's how to do it. I can confirm that this works with Acer bluetooth/cover keyboard and MS Sculpt touch mouse. 1. Pair your bluetooth devices first with android and the with Windows 2. On Windows download PsExec 3.Then from downloaded file copy PsExec.exe in Windows to directory C:\Windows\System32 or to directory where your System32 folder is. 4. Write in the search cmd and run it as administrator 5. Then use command: psexec -s -i regedit.exe 6. Now go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BTHPORT\Parameters\Keys 7. From \Keys you can find your paired bluetooth devices. First there is the devices bluetooh mac address and 32 numbers long linkkey. Now write those linkeys and mac addresses up or copy them. 8. Now everything is set on Windows side. Next boot to android. 9. On android you need again for example ES file Explorer and R/W rights 10. With file Explorer fro root go to /data/misc/bluedroid/ 11. Open file called BT_config.xml 12. From text find your devices using mac address 13. When you find you devices mac addres scroll down and you should see line with linkkey and 32 number code. 14. Now take that 32 number code you got from Windows 15 You have to change it little so the linkey works and here how it's done: for example your Windows linkkey is "12345678qwertyuiasdfghjkpoiuytre" now set it as 8 number clusters like this "12345678 qwertyui asdfghjk poiuytre" Now you have to reverse those 8 number clusters Take the set on far right "poiuytre" and mark it like this "po iu yt re" Now reverse those pairs like this "re yt iu po" Now "reytiupo" this is the first line in the new linkkey Do the same for other three cluster. After it's done this example linkkey looks like this "reytiupojkghdfasuityerqw78563412" 16. When you have your modified Windows linkkey ready you can just replace the old one from the file BT_config.xml 17. Now just reboot android and your keyboard and mouse should work. I've found that sometimes when switching from Windows to android bluetooth doesn't connect. Just reboot android and your bluetooth devices should connect. I would have posted this on deveopers site where people visit more often but you need 10 posts and this is my first one so if you can you should link my post there so more people can enjoy these instructions. Thank you for reading this and don't forget to like it :good:
Anyone know where to find the source code for this?
Unlock Bootloader on Android 8/9 (Testpoints, DC Phoenix) [NOT FREE]
Hello, I just found a way to unlock your bootloader on Android 8 (and possibly 9). This method may also work on other phones if they were released with pre June 2018 Android 8 (where the patch for this "exploit" was release as a Android security patch). Just make sure to use the appropriate versions for your phone (also search for a proper board software for your phone) If your phone is on Android 8 with a security patch lower than June 2018 or on Android 7, you can just buy 4 credits here, then follow this tutorial. If you are on a higher security patch than June 2018 (also called GPU Turbo in changelogs by Huawei) or on Android 9 (untested), follow the following steps: Requirements DC Phoenix (72h timed license costs 19€) Accessible testpoints (phone needs to be opened) Step 1: Write down your IMEI(s), SN, MAC addresses and the current version you are on (e.g. 8.0.0.385C432) Step 2: Buy DC Phoenix and install it Step 3: Just follow steps 1 - 4 from this tutorial. If you are having trouble enabling manufacturer mode in step 4 because the rom is in chinese, follow this video which shows where to click. HCU will also output the bootloader code in the log, which you should write down. Step 4: Now we are doing things a bit differently than in the linked tutorial above: In DC Phoenix click on "Download files" and search for the Android version you had before downgrading to the chinese Android 7 testrom (e.g. 8.0.0.385C432). If you can't find the same one, use a higher one (focus in the 385 part which is the build, also called B385. also make sure the C number matches because that is the region). You should be able to find the main update.app and one customization update.app file. If you have problems with DC Phoenix because it does not enter upgrade mode, put it there manually (described in step 1 here). Your phone should now boot up. To a working android 8 version. If it boots with a google/android logo and your settings says something like "0QT6" for the version, you need to go to to androidhost.ru and search for your phone. It should yield a few results, just pick the same version (or a higher) you flashed with DC Phoenix (e.g. for 8.0.0.385C432 it's this one). There will be a document detailing how to install it via DLOAD (use force upgrade method). After that, your C numer should be fine and updates can be installed (you can update to android 9, then unlock you bootloader via the code from HCU and then install a custom rom) That's it basically.
p40 pro downgrade drove me nuts
I have ELS-NX9(C636R4), managed to downgrade from EMUI 12 to 11, but i couldn't downgrade it to 10.1.0.131 or lower to get lzplay working any more. i have spent more than 10 days on it, burned midnight oil and no luck. 1) I tried hisuite 610 with proxy v3.0.1, but site (https://professorjtj.github.io/v2/) can only provide 10.1.0.158. no lower version. if I tried to use the old one (https://professorjtj.github.io/) by fetching individual base, cust, and preload for 10.1.0.114, hisuite always got update EMUI 12 instead of the old roll back version. 2) I found a firmware els-nx9-10.1.0.114(C636E8R4P1) online from this thread: https://forum.xda-developers.com/t/downgrade-els-nx9-from-182-to-131-for-gms.4246379/, put it on sd card, dload, but it always shows the error: incompatible version. why???? can you please shed some light? million thanks
finally I got it work. 1) the MOST important thing: change your DNS server to 114.114.115.115 and make sure restart the proxy and hisuite again. it is described here: https://forum.xda-developers.com/t/...news-discussion-support.4346741/post-86489617 and my comments here: https://forum.xda-developers.com/t/...ernet-connection.4032695/page-2#post-87199475 2) I followed the video in post #106. [badmania98] Huawei P40 (Lite, Pro, Plus) Guides, News, Discussion & Support Hello! Because I answered to the same questions on different threads, I decided to create this thread, where I will provide my experience to you, in one place. The followings messages (2-7) contain all major info and tutorials links from this... forum.xda-developers.com and used: the proxy 2.4.0 and hisuite 550_ove in the attachment. please make sure: 1) you run both in admin 2) hisuite the setting has proxy 127.0.0.1 and port 7777 basically, A) you start hisuite first as admin and connect phone with it. then start proxy as admin, clear all fields in package url and package name, then follow the following steps in 3) to select rom, proxy UI will be automatically populated. B) in proxy, select roll back OS, and click on set up. C) restart hisuite as admin because it will be closed in step B. 3) then used the following version 10.1.0.122 from https://professorjtj.github.io/ by choosing model: ELS-N29, region C636 and target version: 10.1. later now lzplay worked fine. also notice phone will lose usb connection capability after the downgrade, thus I needed to use huawei nm card for later store installation usb capability will be resumed in the future after phone update to emui 11.0.0.249 version
for my own record ELS-NX9, C636R4, the following package urls are package names: base: http://update.dbankcdn.com/download/data/pub_13/HWHOTA_hotaMigrate_900_9/e3/v3/26d5deaede104f5fb6055f988d7eb62a/ ELS-LGRP4-OVS 10.1.0.122 393319 cust: http://update.dbankcdn.com/download/data/pub_13/HWHOTA_hotaMigrate_900_9/03/v3/55c56bb1de574079b24b990b8b289251/ ELS-N29-CUST 10.1.0.7(C636) 384169 preload http://update.dbankcdn.com/download/data/pub_13/HWHOTA_hotaMigrate_900_9/90/v3/32563083177f4d25a05fb69b252f1470/ ELS-N29-PRELOAD 10.1.0.1(C636R4) 382875
damn, after upgrade to EMUI12, I got the error : the device is not play protect certified try this, it didn't work:
tried the following steps and it worked again, not sure how long it is going to last: -turn off wifi -settings-> apps-> apps -> show system processes(...) -> search google -google service framework(version 10), clean cache + manage storage(clear all data) + force stop -google play service, clean cache + force stop // note: no manage storage in this step -google play store, clean cache + manage storage(clear all data) + force stop -reboot -settings-> apps-> apps -> show system processes(...) -> search google -google play service, clean cache + manage storage(clear all data) + force stop -reboot -enable wifi the above steps are from this magic video:
How To Guide How to un-freeze an unresponsive Samsung Galaxy A32 5G with reboot, reset, factory reset, odin mode, download mode, android recovery mode & debug mode
Recently I had to replace my Samsung Galaxy A32 5G under warranty (losing all my sdcard0 data) because my previous unrooted free T-Mobile A32-5G was frozen, so what I want to do for the future is document, in words, the exact steps to copy data off and to unfreeze & reload new firmware onto the unrooted T-Mobile SM6U I have, for me in the future (if needed) and for others (if they need it). For the hardware modes below, I'm heavily borrowing from this YouTube video titled Samsung a32 5g Hard Reboot - Download Mode But I'm doing all the steps myself and writing them up step by step so they are extremely clear to anyone (and I'm adding information). Wake Click power button to wake the phone (assume this fails) Shutdown or Restart Hold both volume down & power button to shutdown/restart (assume this fails) Fastboot Mode Connect the A32-5G to the Windows PC via USB C:\> adb devices C:\> adb reboot-bootloader In red, "fastboot mode... " shows up on the phone You can now run fastboot commands, such as: C:\> fastboot flashing unlock Debug Mode (mandatory) Settings > About phone > Software information > Build number (press 7 times) This enables Developer mode (if you don't already have it enabled) Settings > Developer options > USB debugging = on Settings > Developer options > Disable adb authorization timeout = on (otherwise authorization is revoked in 1 to 7 days) Settings > Developer options > Default USB configuration = Transferring files Settings > Developer options > Stay awake = off (but know this exists to turn it on if your screen becomes cracked) Debug Mode (optional) Settings > Developer options > Wireless debugging = on Settings > Developer options > Quick settings developer tiles > Wireless debugging = on (that adds a brand new tile to your pulldown area) Permanently add that new "Wireless debugging" tile to the front of your swipe-down quick tiles since this button goes off whenever Wi-Fi is turned off Android Recovery Mode Hold both volume down & power until the screen cycles past the poweroff/restart screen to a black screen and then hold both volume up & power until the phone cycles past the "Secured by Knox" screen and keep holding until you see Android Recovery mode which has the following options, selectable by your volume button and executed when you press the power button with any selection below highlighted. The screen will be black with orange writings saying "Android Recovery Mode" and the following options... Reboot system now Reboot to bootloader Apply update from ADB Apply update from SD card Wipe data/factory reset Wipe cache partition Mount /system View recovery logs Run graphics test Run locale test Power off Repair apps Recovery mode (using the PC) C:\> adb devices C:\> adb reboot recovery That will put your phone into recovery mode Download mode (aka Odin mode) With the phone turned off, press & hold the volume up & volume down & power buttons and plug in a USB cable from the PC at the same time as you're pressing the three buttons to put the phone into Download Mode (also known as Odin Mode). The screen will turn light blue saying... Warning A custom OS can cause critical problems in phone and installed applications. If you want to download a custom OS, press the volume up key. Otherwise press the volume down key to cancel Volume up = Continue Volume down = Cancel (reset phone) Side key = Show Barcode {IMEI, SN, Device ID} In summary, my last A32-5G was toast because I didn't know to access it from the computer with USB debugging on, nor did I know how to reload the firmware, so I don't want that ignorance to happen to me or to anyone else moving forward - which is why this thread is created so we can all pitch in. What we need to add to this are the steps to access an A32-5G phone to mirror it over USB using FOSS scrcpy tools when the screen is unresponsive, or at least to copy the data off the sdcard0 but that will be only for those who already had the foresight to set USB debugging on permanently. 1. First let's outline all the ways to get the Galaxy A32-5G into debug mode, odin mode, download mode, factory reset mode, android recover mode, etc. - all of which I tried today. 2. Then let's run through a firmware recovery process using Odin & Samfw - which I have never done so I rely heavily on others. Note the "official" ODIN is here for flashing stock firmware. 3. Then let's recover Samsung firmware again, this time using Odin & Frija - which I have never done but I will try soon. 4. Then let's cover how to mirror your screen over USB (and later, over Wi-Fi) - which I do all the time. 5. And then let's cover how to mount the Android file system (both sd cards) over Wi-Fi as Windows drive letters using WebDAV - which I do all the time. 6. Then let's add a section on how to recover your old adb authentication keys if they have expired so that you can again trust the computer. Linux = ~/.android/{adbkey,adbkey.pub,adb_known_hosts.pb} Windows = C:\Users\you\.android\{adbkey,adbkey.pub,adb_known_hosts.pb} macOS = ? Android: /data/misc/adb/adb_keys 7. I don't know if the A32-5G SM6U can be rooted yet, but if it can be rooted, I'll likely add a section on how to root it after that. This is required reading to understand the terminology, all of which is new to me (and likely to those of you who read this). And this is required reading for the OEM Unlock option. -- If you've enjoyed it or it has helped you, a thumbs or or thanks is always appreciated! Feel free to share and link to this thread for newbies to messing with Android devices like I am.
Here is how to download firmware using SAMFW & how to flash with Odin. (make sure you get the right odin!) The assumption is the first post was followed which is to proactively: 1. Turn USB debugging = on 2. Connect by USB cable once to a trusted PC & save the authentication 3. Turn off the automatic release of those authentication keys 4.

Most (if not all) are USA files, so I arbitrarily selected one of the "AIO" CSC (whatever that means) files and that brings up three files that are for Android 12, the latest being: Build Date = 20221012183750 Download the firmware flash for Samsung Galaxy A32 5G with the code is SM-A326U.

Run that unpacked executable file on Windows with its associated ini file in the same directory to make sure it brings up the Odin GUI which makes no sense to a noob like me. (Need to add more here since this is a critical step in the process which has no good instructions yet). OK. I think I got it. See Odin file upload steps below. 5. Put the Samsung A32-5G into "Download Mode" by holding volume up, volume down, and power and then right away plug in the USB cable from the computer port such that all four are done simultaneously. Immediately this puts the phone screen blue which is apparently Download Mode (aka Odin Mode) which will say... Warning A custom OS can cause critical problems in phone and installed applications.

In the Odin tool on Windows 10, you have two use models, the first of which is to add the five BL, AP, CP, CSC, and USERDATA files separately, or together as one HOME_CSC file. I don't know where to load the HOME_CSC file so I'll load the five BL, AP, CP, CSC & USERDATA files separately into the Windows Odin GUI (the CSC and HOME_CSC being different in that the home version is said to not wipe user data).

In Windows Odin, click the CP button and navigate to the file named CP_A326USQS8BVJ1_CP23036338_CL24355525_QB57258298_REV00_user_low_ship_MULTI_CERT.tar.md5 In Windows Odin, click the CSC button and navigate to the file named HOME_CSC_OYN_A326UOYN8BVJ1_CL24355525_QB57258298_REV00_user_low_ship_MULTI_CERT.tar.md5 or CSC_OYN_A326UOYN8BVJ1_CL24355525_QB57258298_REV00_user_low_ship_MULTI_CERT.tar.md5 (the difference is said to be the HOME version doesn't wipe user data clean). In Windows Odin, click the USERDATA button and navigate to the file named USERDATA_AIO_A326USQS8BVJ1_CL24355525_QB57258298_REV00_user_low_ship_MULTI_CERT.tar.md5 where the "home_csc" is said to not wipe userdata but the "csc" will wipe user data. 7. Make sure re-partition is NOT ticked in the Windows 10 Odin GUI "Options" tab which has the following settings by default [x] Auto Reboot [_] Nand Erase [_] Re-Partition [x] F. Reset Time [_] DeviceInfo (mine is grayed out) [_] Flash Lock 8.

Here is how to mirror the phone on the desktop over USB or over Wi-Fi using the FOSS scrcpy software. 1. Read the FOSS scrcpy readme explanatory file. [https://github.com/Genymobile/scrcpy#readme] The two fundamental steps are C:\> adb devices (That should report the adb-name-of-your-android-device.) C:\> scrcpy -s adb-name-of-your-android-device (That should mirror your phone onto the PC over USB or Wi-Fi.) 2. Download both the adb & scrcpy commands from this zip file. [https://github.com/Genymobile/scrcpy] Note that you can use any adb from anywhere so if you already have adb from Android Studio, then use that if you want to. 3. Turn on USB Debugging & default mode is file transfer. 4. Connect your Galaxy A32-5G to the PC over the USB cable. The notifications should say "USB for file transfer". 5. For this test, I purposefully turned off Wi-Fi on the phone so that the connection would only be via USB cable. 6. If necessary install Windows drivers to ensure the phone shows up as "Galaxy A32 5G" on the Windows network. 6. Run the adb daemon and obtain your device name over USB. C:\> adb devices You should see something like: ABCD##ABCDE device x. Run scrcpy to mirror the device onto your Windows 10 PC. C:\> scrcpy -s ABCD##ABCDE Where the "1ABCD##ABCDE" is the unique name as reported by adb but if you only had one device connected to the adb daemon, you don't even need that '-s' option; yet it's a good habit to use it. At this point all the following work seamlessly together Your PC will show what's on your phone screen. Your PC mouse will manipulate your phone screen. Your PC keyboard will type into your phone screen. Your PC & Android clipboards will be interchangeable.\ Here are some useful things you can do with scrcpy. To take a movie of the entire session (on either USB or over Wi-Fi): C:\> scrcpy --record foo.mp4 C:\> scrcpy -r bar.mkv To perfectly screenshot just the phone window on demand in Windows: C:\> Irfanview Irfanview:Options/Capture Screenshot > (o)Foreground window - Client area File name: capture_$U(%Y%m%d_%H%M%S)_### (Or you can automatically capture every half second or whatever) DETAILS: 1. Install adb on Windows as per instructions here. <https://www.xda-developers.com/install-adb-windows-macos-linux/> <https://dl.google.com/android/repository/platform-tools-latest-windows.zip> <https://dl.google.com/android/repository/platform-tools_r31.0.3-windows.zip> Note you do not need to be root on the phone nor admin on the Windows PC. Note: You can skip this step if you ONLY want to run scrcpy as scrcpy comes with its own adb which works fine for that purpose. 2. On the phone, check if you have Developer Mode turned on. Settings > About phone > Software information > Build number If you tap once & it says "Developer mode has already been turned on" then you don't need to tap it 7 times to turn Developer Mode on. 3. On the phone, enable the USB Debugging mode option. Settings > Developer options > USB debugging = on 4. Connect your phone via USB to the PC & run a quick test. C:\> adb devices On Windows you will see some debugging information: * daemon not running; starting now at tcp:55555 * daemon started successfully List of devices attached ABCD##ABCDE unauthorized On your phone’s screen, you should see a prompt to allow or deny USB Debugging access which you should grant permanently for this computer so that when the screen is broken, it will still connect! Grant USB Debugging access when prompted (and tap the always-allow check box if you want). Then run the command again: C:\> adb devices List of devices attached ABCD##ABCDE device 5. From the PC you should now be able to access even the phone root filesystem. Optional test: C:\> adb pull /system/etc/hosts .\hosts.txt [That should copy the Android hosts file over to your Windows machine.] Find the number of packages you have which have "google" in the name. C:\> adb shell pm list packages google | find /c /v "" 6. And from the PC, you should now be able to bring up Android Activities. Optional teset: Bring up the gms "Reset AD ID" Activity on Android from Windows: C:\> adb shell am start -n com.google.android.gms/.ads.settings.AdsSettingsActivity That should pop up the "Reset AD ID" settings page on your phone. [GMS is a set of "google mobile services" products native on Android.] You can close that page on Android from Windows by running this: C:\> adb shell am force-stop com.google.android.gms Which you can put into a "closegms.bat" one-line file for convenience. 7. Obtain the Windows "Screen Copy" code to mirror the Android screen. <https://www.khalidalnajjar.com/take-screenshots-of-secure-conversations-on-android/> <https://github.com/Genymobile/scrcpy> Save to C:\installer\editor\android\scrcpy\scrcpy-win64-v1.23.zip Name: scrcpy-win64-v1.23.zip Size: 35446869 bytes (33 MiB) SHA256: D2F601B1D0157FAF65153D8A093D827FD65AEC5D5842D677AC86FB2B5B7704CC Extract to C:\app\editor\android\scrcpy Note there is an adb.exe which comes with that zip file You can now interact with your phone using the Windows kebyoard & mouse 11. To record a mirrored Android session as an MP4 video run this: C:\> scrcpy --record file.mp4 C:\app\editor\android\scrcpy\scrcpy-server: 1 file pushed, 0 skipped. 1.4 MB/s (41123 bytes in 0.027s) [server] INFO: Device: samsung SM-A326U (Android 11) INFO: Renderer: direct3d INFO: Initial texture: 720x1600 INFO: Recording started to mp4 file: file.mp4 Note you can press control+c to end the recording when desired. 14. If desired, use the TCP/IP Wi-Fi connection between Windows & Android which requires the USB connection first, and then you can disconnect after establishing the Wi-Fi connection. C:\> adb connect 192.168.1.2:5555 Where 191.168.1.2 is the IP address of your phone on your LAN. C:\> scrcpy Or you can establish the Wi-Fi connection from the start but this always requires interacting with the screen first. (WORK IN PROGRESS TO ADD THESE STEPS.) I do this all the time so I just need to document it.
This is a placeholder work in progress to document the WebDAV solution which enables you to mount the entire Android file system onto Windows 10 as drive letters (one Windows drive letter for each sdcard). I do this all the time so I just need to document it.
This is a placeholder for recovering old keys if you no longer have the computer trusted and you can no longer access the screen. Accessing An Android Device With Broken Screen Via ADB and Unauthorized Machine in 2022 Just as a datapoint, while I use a variety of adb implementations, I looked for these stored keys and found the files, albeit they were rather old. adb shell ls /data/misc/adb/adb_keys Directory of C:\Users\username\.android 11/25/2022 03:39 PM <DIR> . 11/25/2022 03:39 PM <DIR> .. 12/14/2020 01:27 PM 1,732 adbkey 12/14/2020 01:27 PM 709 adbkey.pub 11/25/2022 03:39 PM 936 adb_known_hosts.pb 08/06/2022 08:16 AM 185 analytics.settings 12/16/2020 12:37 AM <DIR> avd 12/14/2020 04:57 PM <DIR> breakpad 08/06/2022 09:15 AM <DIR> cache 12/14/2020 01:26 PM 2,107 debug.keystore 12/14/2020 01:29 PM 0 debug.keystore.lock 12/16/2020 12:36 AM 4,640 emu-last-feature-flags.protobuf 12/16/2020 12:36 AM 67 emu-update-last-check.ini 12/16/2020 12:37 AM 119 maps.key 12/16/2020 12:36 AM 171 modem-nv-ram-5554 12/14/2020 12:59 PM <DIR> studio 10 File(s) 10,666 bytes Note that I do not use the adb inside of Android Studio much, since any adb works for what I use it for, so this is probably a feature of AS perhaps? Do you think _old_ keys would work in an emergency situation? This is something we should flesh out for the general user.

I tried the methods to root described here, the first test is Go to OneClickRoot on any web browser a. I clicked on "Samsung", b. and typed the model "SM-A326U", c. and selected "Galaxy A32 5G (SM-A326U)" d. Then I selected "Android 12" as the Android version e.

This is all very very very confusing. Either we can root this Galaxy A32-5G SMA326U or we can not root it. Which is it? Has anyone been successful with that TWRP/Bootloader unlock process with a bootloader fifth-from-right digit of 8?
NO FOR THE BILLIONTH TIME
TimmyP said: March 2021 is bootloader 5. The device was rootable though that update. Anything after that no known exploit im sure the people I paid to root mine here would be "advertising" their services if there was. Click to expand... Click to collapse Thanks for the confirmation that anything with a bootloader version of 6 or above (mine is 8) can't be rooted by anyone. Settings > About phone > Software information > Baseband version = A326USQS8BVJ1 All the articles that say the Galaxy A32-5G can be rooted must have been done using the older bootloader (version 5 or lower).
