Will I lose my data when using Recovery's Apply update from SD card option? And, if so, will I lose data on the phone, on the memory card or everywhere else? Phone: Samsung SM-A107F/DS (Galaxy A10s) System: Android 11, One UI Core 3.1 Bootloader version: U8 Recovery: stock Root: **NO**

I have an old tablet(Lenovo Phab 2 ) with Android 6. I need to upgrade the Android version to 7 or heigher to run some special app for my business. I checked TWRP and Lineage OS. There were some tutorials with the links. But those links are broken now. So I came to know that this is a common scenario to all who need to upgrade their old Android device. What is the generic solution for this issue?

I have Cubot KingKong Mini 2 (Android 10 smartphone) and the new version of the firmware is available on the official website of the manufacturer: https://cubot.net/Support/id/60/cid/16.html#hh It contains "***minor bug fixes***". They also gave instructions on how to update firmware: via *PC*, using *SP Flash Tool*. My question is: does the "standard" update from *Android app settings* (System > Advanced > System update) also include the same bug-fixes? If so, then I don't have to do anything via *PC* & *SP Flash Tool*. I tried to find the answer by searching on Google, and on some sites it says that "*firmware update = Android update*" (which means that I don't have to do anything via PC?), while on others it says that it is not (which means that I would have to update firmware via PC/*SP Flash Tool*?).

I have a device that uses UBIFS instead of YAFFS, and the system partition is truly read-only. As a result, I can only modify the system partition by completely reflashing it. My device is also not fastboot-friendly, so the only way I can flash it is to modify the manufacturer firmware. Naturally, I would like to root it this way. If I modify the manufacturer firmware, **test it in an avd**, and it **WORKS**, and then flash it to my device using stock recovery, what are the risks/chances that something will go wrong?

I am trying to flash a customized update.zip on a pre-Kitkat device. In the zip there are 2 files with SHA1 signatures of other files in the update. But they have different signatures for the same files. Example: META-INF/MANIFEST.MF: Name: system/lib/libcustom_jni.so SHA1-Digest: +PhV5XphkQTNTyM2TSRTeiaDlCA= META-INF/CERT.SF: Name: system/lib/libcustom_jni.so SHA1-Digest: 7ooFhqk1oYWF5pmVuSAhF2pFVNw= I can get the first one using: sha1sum system/lib/libcustom_jni.so | cut -d\ -f1 | xxd -p -r | base64 +PhV5XphkQTNTyM2TSRTeiaDlCA= How is the second one computed? The second file has a hash of the first file, so maybe the other hashes are salted with the first file or something? From what i found in java doc the SHAs should be identical, except all SHAs are the version 1 in the original update.zip. It seems hat the certificate used to sign the update was the android test one so it should work, but aborts instead.

I'm in TWRP after a factory reset and I'd like to avoid to install some OS to update TWRP with the [TWRP update app TWRP from within TWRP? I have a Moto G2014 and previously had Cyanogenmod 13 installed.

I've a wileyfox swift (crackling) and I've installed LineageOS 14.1-20170213-NIGHTLY-cracking + GApps through TWRP 3.0.3. The problem is that when I try to update it through the UI or manually (downloading the .zip file from https://download.lineageos.org/ and installing it from the recovery) TWRP returns an error (status error 7). I tried to downgrade TWRP to the 3.0.0 version but nothing changed. How can I update my phone without wipe everything?

I am currently running the April 29th build of LineageOS for MicroG 16.0 on my OnePlus 5 (cheeseburger). I tried to update the device using the built in Updater, but the device just rebooted into TWRP and showed the TWRP logo screen for some time. After that, I got this error message: Checking for MODEM build time-stamp 2019-07-18 14:56:39 Error: This package requires firmware version 9.0.7 or newer. Please upgrade firmware and retry! Updater process ended with ERROR: 7 Error installing zip file '@/cache/recovery/block.map' Done processing script file After searching for a solution, I decided it would be best to just backup my data and reinstall Lineage. After looking through my options, I decided a Nandroid backup through TWRP was my best option. So, I tried to take one. This was the result: createTarFork() process ended with ERROR: 255 Backup Failed. Cleaning Backup Folder. If I adb pull my recovery.log, this is where I get my errors: E:tar_open error opening '/data/media/0/TWRP/BACKUPS/[serial_number]/2019-08-10--23-11-06_lineage_cheeseburger-userdebug_9_PQ2A190405/data.ext4.win000' Error creating backup. I:Error creating tar '/data/media/0/TWRP/BACKUPS/[serial_number]/2019-08-10--23-11-06_lineage_cheeseburger-userdebug_9_PQ2A190405/data.ext4.win000' for thread 0 Error creating backup.

The strange thing is that the day before yesterday when I deleted the files in the /data/media/0/TWRP/BACKUPS/[serial_number]/ and then tried to perform the backup again, it regenerated files in the same directory, causing the same error. I also find it strange that the files that are causing the backup to fail seem to be backup files as well, although I've never performed a successful Nandroid backup on my device. So, what can I do to fix this error and finally be able to backup and update my device?

I installed LineageOS on my OnePlus One, and today I got the latest nightly. The OTA update system downloaded the file, and I clicked install. However, it says > Note: This feature requires a compatible recovery or you will have to install it manually. Then it sends me to recovery and nothing happens. Can I get some help as to how to update?

Does anyone know if there is a ROM of Android 8 or higher for the cellphone Asus 4 Max? If it does not exist, will be an official update for this model of cellphone?

I have a problem. I am new in the domain of android customization and that is why I am testing. I have a PDA file for my old GT-S6102 Galaxy Y, which contains the following files: - boot.img - param.lfs - Sbl.bin - system.img - userdata.img I also downloaded a custom ROM from the internet called evo_x2.1 (evo_x2.1.zip) which contains the following files: - META-INF (folder) - system (folder) - installbusybox (file) Normaly this file is supposed to be put on /sdcard and update the system partition only from recovery mode. But I have a question: Can I edit my PDA file mentioned above by inserting this ROM in it? (so that when I flash this firmware with odin into my phone I will no longer have to update it with this ROM separately afterwards, manually) I tried to create a system.img which contained the files included in the ROM file and replaced the system.img in the PDA file with the system.img I just created from the ROM file.But when I try to flash the PDA with Odin, it crashes while analyzing the file. NOTE: there is no md5 hashsum at the end of the PDA so there is no problem concerning the integrity of the file. Thank you, and any observations are welcomed.

We have two Redmi note 4 phones. In both of them the official update for miui 9 also android nougut (same package total of 1.3 GB) came. In one of the phone it updated smoothly but in the other phone it is displaying - **Try using full rom** *Interesting fact is that the total 1.3 GB package everytime gets deleted after unsuccessful update attempt* Tried many times not functioning. Please help to fix this bug.

I would like to know how is the default launcher set after a factory reset. What files are in charge of telling the OS, for example, that the Touchwiz app is the default launcher for Samsung devices. I do not want to replace the launcher, that is something I already know how to do. This is a very specific question regarding how the os works. I am interested in doing a system update via recovery and changing the files that tell the OS which app is the default launcher, in order to tell it that my newly flashed app (flashed in system partition) is. I look forward to your response. Thanks in advance. EDIT: As stated, Samsung is just a given example but it is one of an endless list. This is an os general-behaviour related question not manufacturer specific.

I have a Samsung Galaxy Note 4 (N910a), and the WiFi doesn't work. I think it's because it has an old firmware version, so I tried to update it, but when in recovery and trying to update from the SD card, it says "Update from external storage is disabled." the same thing happens with adb.

I know that mediatek doesn't share their source code (you can buy it), and what I was wondering is does any MTK device gets updates when newer Android version rolls out, and not just new versions, just does they get software updates? I asking about stock ROM-s made by phone manufacturer. Mostly interested about LG devices.

I got an update this morning for my Galaxy A5 (2015), to update from. Lollipop 5.0.2 to marshmallow 6.0.1 and now I keep getting this pop-up every 5 seconds. Screenshot (click to enlarge) I can still receive text messages but I can't go into network settings for my SIM card. How do I fix this? Any help is appreciated.

Yesterday I updated from this snapshot version **2016-04-18 17:30:08** to the last one **2016-08-20 00:21:07** (bullhead) Everything looks in its place, but yesterday the device was keeping restarting, today it's stable. I tried to reboot it by myself and when boot it says: **There’s an internal problem with your device. Contact your manufacturer for details.** Any solution?

I couldn't find any answer on how to install any android version higher than JellyBean on Galaxy Beam, do I need to buy a new phone?

I am trying to update system to either Android 5.0 lillipop or Android 4.4 KitKat. I formated sd card to FAT32, and moved rom there.
When in recovery I used apply update from external storage

signature verification failed I downloaded both roms from here the same thing happened for second rom. I am using Onetouch EVO7. if this may help recovery says recovery system v4.00 Also I can not use fastboot to connect with device (waiting for device), so I am using adb instead. Device is rooted using kingo root

I have a Samsung Galaxy Note 10.1 that has been infected with some viruses really badly. After factory defaults, as soon as it connects to the internet it starts downloading some apps and advertisement windows pop up like every 10 seconds. Things I tried: - Installed AVG AntiVirus, CM serurity, Clear master - It helped me delete some files of the virus but did not solve the problem - Booted into recovery mode: - Wiped cache partition - wiped data/factory reset - Booted into Odin mode: - Product Name: GT-N8010 - Custom Binary: Download: No - Current Binary: Samsung Official - System Status: Custom - Tried to software update - Message: Your device has been modified, software updates are not available. What can I do to get rid of the virus and be able to software update normally?
