[Q] Can anyone boot any Smartphone from the external SD Card? - General Questions and Answers

These are my current problems:
1) I lost my Galaxy S3 overboard!
2) I had not made a backup because I detest Kies. Kies crippled my PC performance and hid my backed up (*.sbu) files from the PC file system.
3) I want to avoid the use of all proprietary software on my PC in order to manage my backups (including OS backups).
Proposed solution:
1) Buy a replacement Smartphone (a Galaxy S4?) which has an external SD Card slot.
2) Flash a custom bootloader with complete Backup / Restore functionality.
3) Backup Function: A complete phone Backup, (i.e. OS, Apps, Data and MyFiles), is made to a new folder in the root of the external SD Card. I can give this folder any name, e.g. “OriginalPhone” or “2013-04-21” etc.
4) A single file in the root of the external SD Card called “current.txt” contains a single folder name - that of the default folder for booting, e.g. “2013-04-21”.
5) Normal Booting uses the files originating from the folder specified in “current.txt”.
6) If there is no change detected in the boot files of the “current” boot folder, the phone boots “normally” from the OS copy in NAND flash if this results in a quicker boot than booting directly from the external SD card.
7) Booting with a combination of keys enables the Bootloader Restore function which allows the user to choose the boot folder to restore from.
8) I can use my PC file manager to manage all OS and data files for archive, backup and restore purposes. I will not need to use any proprietary software!
9) If I lose my phone again, I simply buy the same model as a replacement, change the bootloader, copy my most recent backup folder from my PC to a new SD card, insert the new SD card into the phone, and restore my "complete phone".
Can anyone help me to create a custom bootloader with complete Backup / Restore functionality that can boot any Smartphone from the external SD Card? Thanks in advance!

These are my current problems:
Hello
It is the second time, I buy a Smartphone and after the garanty time (1 month after it due to software error my smartphone doesn't work anymore.)
I have bougth a honor 7 premium. During installation process may be due to obsolesence programmed or battery low during loading, it stucked I think in boatloader /EMUI (emui install failed error). the honor image stays and also after wipe cash partition and wipe to factory reset, it doesn't start.
I would like to start and if possible flash a new android SW on the honor 7 to be able to connect to it.
Actually I can not connect it with the PC. It is not visible.
Is it possible? Do you have any boot SW I can put on SD card. It would be very helpful.
My wife needs his mobile before leaving for 3 weeks on monday.
Feedback would be very greatfull
thanks in advance

UNroot and back to GB stock on Huawei u8510-1 Blaze aka Ideos X3

To root plz follow guide: http://theunlockr.com/2012/05/22/root-huawei-ideos-x3-blaze-u8510-install-clockworkmod-recovery/
but the unroot guide did not work possibly coz of GB(GingerBread) stock but after a few min i accentally when to storeage in settings and was able to recover back to GB stock.
the UNroot method is the same up to step 7 of the unroot guide(http://theunlockr.com/2012/10/24/how-to-unroot-the-huawei-ideos-x3-blaze-u8510/) ie:
Stock download source (http://www.huaweidevice.com/worldwi...&directoryId=3372&treeId=0&tb=1&type=software) -get correct model number from behind the battery.
I. Before You Begin:
1. You must have a SD card formatted in FAT32 file system.(optional but not required, if already in use)
II. Downloading Required Files:
2. Download stock from manufactures source stated above (ie GB stcok for u8510-1 i believe there are only 2 one for tesc0 andPhones4U)
III. Unrooting the Huawei Ideos X3 Blaze (U8510):
1. Download and place the Stock ROM (zip file) on your Desktop.
2. Extract files from the Stock ROM archive to your Desktop. A dload folder should appear in the extract folder called dload and should contain UPDATE.app file.
3. With SD card inserted in your device, connect the device to your PC using the USB cable.( A message should appear click "turn on USB Storage" button)
Note: one can identify the sd card drive letter by the storage size,will not be exact size but approximation of size.
4. Copy dload folder and content to root of SD card (that is should be visible when sd card is opened possibly along with other folders)
5. Disconnect the device after the file has been copied.
Note:a) when the device is connected to PC it will be able to communicate with device, so may appear as its not there(connected to device)
b) plz backup all, as this process WILL DISTROY ALL DATA ON HANDSET!!
c) Check the folder and file is present in SD card by file manager-->sd Card
d) Lastly check batery level is full as a CRASH MAY BRICK THE HANDSET, So if not charge to full before going any further.!!!
Now Simply go to settings-->Storage-->Software Upgrade(scroll to bottom)-->SD Card Upgrade--> "confirm" --> "upgrade"
WILL TAKE "2 MINS"
WHAT TO EXPECT DURING THIS PROCESS (OF 2 MINS)
--------------------------------------------------------------------
STEP1/2 UNPACKING
and by 33% or progress bar reaching one third way, sign should change to read
STEP 2/2 INSTALLING
when completed the phone will boot 3 times with a few mins pause(each boot indicated with a virbration)
a WELCOME SCREEN should appear
"TAP GREEN ANDROID"
a sreen headed SETUP UP YOUR GOOGLE ACCOUNT
CLICK "SKIP"
a sreen headed USE GOOGLE LOCATION
CLICK "NEXT"
COMPLETED .....ENJOY

Can you gain access into a device's internal sd card even though you have a bootloop?

I got into bootloop after installing some apps and I am just wondering if I can access my nandroid backup folder on my PC....coz apparently I need to change the folder name in order to get rid of "MD5 mismatch" during restoration in clockwork mod recovery.
Thanks in advance.
By default, the backup folder is on the sd card. If your device has a removable card, you can just put it into your pc & access it. You can also access it through USB by using adb commands, but you must have previously turned on debugging mode in the settings.
It's also handy to have AROMA Filemanager on your sd card. You flash it in recovery like any other zip (it doesn't make any changes, just launches the file manager). It also comes with a terminal emulator. It's quite powerful, and extremely handy when you can't get your system to boot up.

Will this work on a Blue Life Play 2?
Doesn't anyone know if this will work on a Blu Life Play 2?

Huawei Ascend G6 LTE - Modded b370 -EVOLUTION - All what you need in one ROM!

------------------------- My modified ROM -------------------------
Updated on 07-04-2015
This is a backup from what I have in my phone, modified by me.
Check bellow the new update and let a comment!
Lets see her first! : https://youtu.be/ygulhZFlGjQ
In this version have a New "Face", by default external sd storage is the main storage, have a new bootanimation, a better one core performance ( 90% of the apps use only one core ), better RAM usage, have a Mega Themes pack that will be created in external SD CARD but you can delete the themes you don´t like it, ADB is in ROOT mode, default recovery have busybox tools, new tweaks, two hardreset zip to use with TWRP ( one version install the default recovery again) and auto resize data partition to 4GB!
Data partition is where user data and apps go, by default is 2GB!!! And still have the option of sending the apps to sd card!
And automatically will send the apps to sd card IF YOU HAVE A PRIMARY EXT4 PARTITION IN external SD card, if you don´t have apps stay in phone like default.
This is for #Huawei #Ascend #G6 #L11 #LTE. - European version, i don´t now if works for other countrys.
So, like before...
This ROM is from a backup from my #phone and it was #modded by me, for now everything is working fine but some times issues are only noticed with the use of the device.
My version still #Kitkat #B370 but very diferent from Stock #ROM, have more tools, options and user have Full control from the phone.
Please read all to understand and see what you need to do and how to do it!
One of the best things in this version is that data partition was increse from 2GB to 4GB and if you have a ext4 partition with +/- 3/4GB ( don´t need more ) in your external sd card it will install the all apps there automatically!!!
Advantage of this? You will have a huge store space for the apps!!! And the "#low #storage #space" advise, you will never gonna see it!
If you don´t have it, it will work like default ROM.
To create a primary #ext4 partition in sd card with the size you want, you can use mini partition tool (for windows OS ).
http://www.partitionwizard.com/free-partition-manager.html
This video shows how this ROM works with a external ext4 partition in sd card what means that all apps go to sd card and let internal storage free, the example shows how to create a 8GB partition but is to big...4/3GB i think will do the job:
https://youtu.be/7st6838_aAg
Use a class 10 sdcard, better if is one to use with 4k pictures, it have a better performace!
-> To use it with sd card ext4 partition is better to start from factory reset with the partition already created in sd card!
Or create the partition and flash this ROM!
It have Rashr from #XDA, it is a app that easly can change/flash your recovery and do some other things.
When you flash this ROM it will create in your sd card a folder called recoverys, inside you will find #TWRP ( modde by me to ) and the default recovery.
How to use it? Open #Rashr, give root permissions, select recovery, search in explorer for sdcard1, open recoverys folder choose the one you want and flash and flash it! Is that simple.
And now this ROM will install in your external sd card a flash zip to use with TWRP called Hard_Reset.zip. What it does???
It will reset your phone AND the ext4 partition you have in external sd card!!! Full reset, in phone and in the external sd card ext4 partition! You must flash it with TWRP to work.
>>>>>What this ROM have?
-a better single core performance
-better RAM usage
-external SD card is main storage by default
-Have Huawei App Store
-Ring tone distorcion fixed
- Don´t have a default theme applied but came with a Mega #Themes pack for you to use!
-On idle, in 6h, battery dropped 1% from power.
-#Google #Handwriting
- Har_Reset.zip
-Custom ring tones
-#Data #partition is #resized from 2GB to 4GB
-#Rashr from XDA, its a flash tool to use in phone ( on flash will be create a folder called recoverys with default recovery and TWRP that you can use with Rashr)
-Custom #bootanimation and shutdown animation
- One Hand #UI ( helps to write in keyboard with one hand, you can find in shortcuts bar )
- #Root
- Root tools (Root Browser, ES File Explorer, build.prop editor, etc...)
-Same cosmetic changes ( battery icon, signal reciver and wifi icons edited)

ADVISE!
Always do backup from the ROM you have in your device.
If you have root you can use this tool, it have a backup option, the phone must have ROOT, must have a tmp folder in Windows ( c:\temp ) and 2 GB free in external sd card.
G6Sknife for windows OS

My device is working properly with out any problem so far, some times bugs only be noticed with use and i will update this post with the ROM fixed.
Install it by your own free will, I am not responsible for any damage that may appear in the device.
Lets start! ( If you had any of my other version jump to STEP 3! )
If is your first time in this page start by unlocking your bootloader, and by flashing b118 ROM, if you already have done this skip this 2 first steps and go to step 3:
STEP1: To Unlock the #bootloader, first try this site, but if you don´t have you need to create a account ( free ):
https://emui.huawei.com/en/plugin.php?id=unlock&mod=detail
Insert your data like this example for U10:
http://postimg.org/image/6kddvoboj/
U10-G6, huawei G6-U10, etc..., DON´T WORK! Insert it like image shows.
Example for #L11 model:
http://postimg.org/image/wha6ixm85/
Be sure from the data you are inserting...
Now, with the code, use G6SKnife to install the drivers for Huawei, option ( d ) than turn off the phone, press volume - and power at same time, it will boot in bootloader mode, plug the usb cable, wait if is installing the phone, use G6SKinife again and use option 18, read what is in screen. If was done right the phone will reboot with factory reset and bootloader unlocked.
Step 2: You need B118 ROM #Firmware or a new one than B118 ( B119, B120, etc ) because old versions don´t let to install TWRP...
So lets flash B118:
Download this zip:
G6-L11_20V100R001C432B118_Firmware_West_20European_Channel-Others_Android_204.3_EMUI_202.0_20Lite_05012GFT.zip
https://mega.nz/#!Tl4CnSBR
Key:
!rTuufQZhcyEGGY2_4iUc2S9lPZ61MamYS7OMydYFf1I
Extract the dload folder to PC desktop, paste in external sd card and with the phone OFF, press the volume KEYS and power at same time, hold it, and release power on boot, if don´t turn ON release only power, than volume keys when flash starts.
This video shows the flash from B118 than to Huawei_Ascend_B370_LTE_BB ROM but we gonna do it a litle easy, OK?
https://youtu.be/duF3kWSpgsI
STEP3: Install TWRP but ! you need ! this version, or your flash will fail!!!...
Download this TWRP exe file:
https://mega.nz/#!39olHSqI
key:
!-xrnsx_nYPF4H-IeQXn6znbkn_1TbYUaHaYUx_O0qB4
Boot in bootloader ( must say unlocked in red ). Do you remeber how to do it? Turn off the phone, press vol - and power at same time! Plug the usb cable and execute the file you download!
It will reboot.
STEP4: The ROM!
Huawei_Ascend_G6-L11_EVOLUTION_B370_ROM_V2.0.0.zip
https://mega.nz/#!j9Ay2IYI
Key:
!Z9jQhLr3-kmyBjNicw_q8FZyqp-pjRVlG0h24JYIO-I
Copy to sd card, DON´T UNPLUG THE USB CABLE, why?
Power off the phone, it will boot in TWRP!!!
Now go to install and flash the ROM!
READ ALL WHAT IS WRITE IN THE END OFF FLASH!!!
It will say to GO BACK TO TWRP MAIN MENU -> REBOOT -> ! RECOVERY!!!!!!!
You will go to FACTORY #RECOVERY!
Do a factory RESET!!!
I advise to use a cat10 extreme sd card - normally used for 4k movies and go to settings -> #STORAGE and change main storage to ->SD card.
Done!!!!
>>>>> FIX CUST, CHANGE PROVIDER AFTER INSTALL ROM<<<<
This ROM was edited to vodafone pt but can be changed to your provider.
When you flash it, if you are not from Portuguese Vodafone it will show a bootanimation that say " Change Cust after settings than do a factory reset ".
This is how to fix it with Root Browser, that you can find in ROM, go to folder /DATA and seek the custom.bin file, open it as a text file, you will see something such as example zt/rt, now we left the folder /DATA and go to the folder /CUST , we open it and we will find a folder with the name vodafone, we will change the name of it to the first name that we saw in custom.bin in our example will is zt, use small font, now we entered the zt folder and we will find another folder that his name is pt, let's switch to the second name of our exemple which will be rt, use small font!
Go back and exit the app, do a factory reset. Done!
The video shows how i change cust from hw/normal to vodafone/pt
So ROM is set to vodafone pt, you must do the same to your provider.
Check the video to know how to flash from B118 to one of my old version, is the same with this one to:
https://youtu.be/1rV3NAylyIo
On video you can see one of the advantages of external partition, a default factory reset or flash don´t delete the apps you have it in phone before, it will be installed in first boot! Some times it will take longer if you had to many apps.
The app on video is STORAGE SPACE, was in external partition like you will see on video, and was installed in flash!
ext4 partition is only reset by Hard_reset.zip!!! Default reset don´t "clean" that partition.
Installed your ROM yesterday over the stock firmware of my Huawei G6 L11 B360 . So far working everything working fine and the phone is really responsive!
Except that the app Rashr is not working. It closes immediately. Not really using it so I don't really care but now you know.

How I unbricked "Decryption unsuccessful" The password is correct but... (Apps2SD)

How I unbricked "Decryption unsuccessful" The password is correct but... (Apps2SD)
Hello, I don't usually post in tech forums, I usually the guy that only reads,
but this is the time when i could not find the straight answer to my problem and had to google the solution out of similar posts, so I decided to glue everything together and write my solution to this particular situation,
so I might save a lot of time to someone who got in exact or similar situation.
Sorry for my crappy English, but here we go.
What this post trying to solve:
You stuck at boot loop: "Decryption unsuccessful" The password that you entered is correct but unfortunately your data is corrupt.
and how to make it work Apps2SD with Huawei P9 SD card with enabled password protection.
Basically my Huawei P9 (EVA L-19) with Android 7.0 Nougat got running out of internal space, and i am really a heavy user on apps. Kirin 955 handles just fine as long as it has at least 10Gb of internal free space.
I have SD card 64Gb, but huawei stopped support, native move apps to SD, long time ago. My device is rooted, so I was searching for a solution. There is few apps that can transfer your internal memory apps to SD by using root, but the one that actually worked for me is Apps2SD. The thing is, my SD card is password protected (Huawei native function) I want to keep this function in case of device getting stolen.
Problem is, many third party apps that move your apps to SD, does not know anything about Huaweis SD card password feature. In fact (as far as i tested) only Huawei phone allows you to enter password and show contents of SD card, no PC, or for example Samsung phone will recognize this SD card.
So i was messing with Apps2SD, partitioned my SD card in to 2 primary partitions, 1- exfat, 2- Ext3. It works kinda fine, but after reboot, there is delay, Huawei unlocks SD card after main boot part, and Apps2SD does not understand this and show that it failed to mount second partition.
In this case, Apps2SD starts giving you solutions, one of them is this ADVANCED mounting option. It does not tells u about any dangers, nothing really.
I chose that option to see if it will be able to see second partition contents faster, rebooted - boom bricked.
You see the message: "Decryption unsuccessful" and asks you for decryption password. It might be SD card password, not sure, it does not matter, because you can type ANYTHING and it always say:
"The password that you entered is correct but unfortunately your data is corrupt". And gives you only option: fully data factory reset. Now hold your horses, dont press that. I just knew that this is bull**** and no way
my personal data is corrupted, its just some hadshake issue. (I was right i fully recovered everything up n running)
Assuming you got in this mess, your device must be rooted and you probably have TWRP recovery, cause Apps2SD work only with rooted devices.
To recover from "Decryption unsuccessful" boot message and restore all data and settings:
Got to TWRP recovery by holding power button and volume UP (after phone vibrates, hold both buttons 2sec more and then release power button, and then after 2sec more release volume up, cause if
you do this too fast, u will end up in wifi recovery by Huawei, and it wont work anyway cause your device rooted).
Then go to advanced and file manager, locate sdcard folder (this will be internal memory, not external), you should be able to see all of your personal files! Copy them to flash drive by connecting with OTG.
What we gonna do now is: do a full nandroid backup: TWRP, backup, check: BOOT, SYSTEM, DATA. and do a backup to flash drive connected with OTG or hard drive if it works for u.
After backup is done, go to WIPE, select format data, select DATA partition and see what original file system it uses. Now format in any other system, then reformat again to your original file system.
DATA partition somehow lost its encryption handshake key and this caused the problem, reformatting fixes it.
Now do a full wipe as if you would install new rom, wipe: system, data, storage, cache, dalvic cache.
Restore your previous nandroid backup, reboot to system,now your phone should boot with all the apps and settings just as you left.
You might be missing some pictures and other media in main storage, just connect your P9 with usb cable to pc, and restore previously backed up media from flash drive manually in pc interface (copy paste, replace all),
some small minority files might wont copy, don't worry about it, Im not sure but they are mostly indexing files, all ur media will be back in place.
Now, how to make Apps2SD work with this configuration?
Don't use that advanced method to find SD cards second partition, use any of first 3, the 3rd one worked for me just fine, cause its SU library based one.
Don't move your apps fully to SD, or they will "disappear", move everything except APK, ODEX, DEX (Lib is optional, you usually can move this one just fine). SO basically app core will stay in main storage but cache and app data will be on second SD card. This way, after you reboot your phone, you will have to wait like 3mins and App2SD will link your files to apps itself just fine. It might will show some errors right after reboot, but after Huawei unlocks its card, files will be linked, and apps wont be "gone" cause app core still stays in main storage.
This way i managed to save a lot of space and move most of app storage to SD card, P9 became very responsive, even in 2018 this is a really fast smartphone.
Sorry for a messy post, I'm not a writer, but I hope this helps to someone!
Thanks a lot, you saved my phone-config! ) This step "...and see what original file system it uses. Now format in any other system, then reformat again to your original file system." was unclear to me, as TWRP didn't give me the option to choose a file system, but in the end it worked out fine without just as well.

How did you run into this issue?
If it was due to updating Magisk to v19.x (on Huawei with Nougat / EMUI 5)?
In that case, there is an easier solution, just flash back Boot img with Magisk v18 1 and everything will continue to work as it did (without any need to reformat, factory reset, etc), see

I'm not entirely sure what caused it, but I suspect Apps2SD just like in the original post (I installed/tried to use it shortly before the problem occured).
