That's strange and very very rare event.

Were you using stock Samsung android 10 or Los 17.1?

Do you have twrp backup?

If you are on Los 17.1, you can dirty flash the rom.zip without wiping anything.

If you were on stock Android 10,download and flash the stock firmware, make sure you use home_csc in CSC slot to avoid losing any data. You will loose root btw.

If you have stock android 10 rom and it's twrp backup you can try restoring that.

Worst case scenario, you might loose internal storage data.

Word of advise don't let the phone die.. Put it to charger once it's 20 or 15 %.

This has happened to me once with note 2 and Nokia 5800 XM.

Audio/microphone during calls

I have now tried this guide beginning with three different stock roms. LOS, TWRP etc. install and work beautifully. However, I still have the problem of no audio or microphone during a phone call unless I physically turn on the speaker. otherwise, I cannot hear nor can the caller hear me. I have not experience this using either of the stock roms.

Anyone have an idea of what I can do to solve this issue?

Please!

Hello,

I was using stock android 10. No back ups ? in the end I had to reflash the full phone
[Samsung Galaxy A70 Guides, News, & Discussion] fizzingbees:
That's unfortunate.

Kindly make weekly backups of everything that's important.

Store critical files in external SD card.

Use Google drive for other stuff.

Hello all. I use stock Android 9 with TWRP and Magisk root, works fine. Now i/m thinking about Android 10, but if i understand Step 9 and 10 right (re-installing stock recovery?), its not possible to use Android 10 with TWRP, just with root ?

I flashed my cell phone many times without problems, but when I copy twrp into the extracted AP and pack it with Peazip, Odin aborts with an error in "recovery". So again with the instructions from Garak and everything is fine.
[Samsung Galaxy A70 Guides, News, & Discussion] :
As already probably stated.

Inside TWRP, Before flashing Magisk.zip, I had to go into Advanced, then format (fix contents) for the SD to read 128GB because I used a ROM not for the region I'm in... So in general, I had to do it twice. People need to read the entire thread for a successful result. My only concern was the backing up without TWRP, which smart switch and titanium was and has always been helpful, backups only to SDcard, never Cloud.

And so are the days of our XDA lives..

Instal magisk without twrp

Hei do you know how to instal magisk without twrp?
[Samsung Galaxy A70 Guides, News, & Discussion] LoopZilla:
Hey-o! I am very keen to get LOS on my A70. I am curious if this method will work for the MN model? I noticed the LOS img you have linked to is for the FN model. If this can be done I am a little unsure where I would need to start following your instructions because I have already rooted my phone using BK's root method that's been posted on xda forums. Also, I don't have TWRP installed because I was under the impression that it isn't compatible with android 10 & because TWRP hasn't been setup for an A70. (via TWRP website; A70 not listed in the supported devices)

Thank you for your time,

LoopZilla
[Samsung Galaxy A70 Guides, News, & Discussion] Clasimodo:
Great news:a working TWRP for Android 10 ! But what happens if I would flash this over my rooted device (stock, following the instructions in the OP of this thread). I realise I could simply try it, but I don't dare to do that just now, because I don't have time to restore my phone if it soft bricks. Did anybody try yet?

here is twrp for android 10 galaxy a70 thanks to grarak. ill run through some tests and update the guide accordingly. I do not know if he is building a LOS 17 update but with the new twrp, installs should go more smoothly for those who have updated to android 10.

Great news [MENTION=6698960]MarvinMod[/MENTION] and thanks to [MENTION=4443334]Grarak[/MENTION] [MENTION=6698960]MarvinMod[/MENTION] Can you as so kind to test it and write a thorough guide to root, install twrp on Samsung A70 with stock android 10 afterwards.
[Samsung Galaxy A70 Guides, News, & Discussion] MarvinMod:
Just so were clear, the new TWRP is NOT my work. all thanks for that goes to Grarak. :)

im testing right now and twrp works on stock 10. download the file, extract recovery.img and repack recovery.img with peazip to recovery.tar and flash with odin. I will write guides but ill need to do some flashing first and check everything. will update as soon as I complete testing. :good:
[Samsung Galaxy A70 Guides, News, & Discussion] fizzingbees:
Oh yes.

Thanks for your honesty

And thank you for taking out the time to test and write guides for benefit of others
[Samsung Galaxy A70 Guides, News, & Discussion] MarvinMod:
Okay, i have not written any guides yet but ive tested twrp with both los 17.1 and stock Android 10. Here are my findings.

Los 17.1 works fine and install was smooth but the rom has some issues. 8mp camera which is sometimes laggy and doesnt save to the ext. Sd card, the flashing dot where the proximity sensor is, screen doesnt show the caller info bright enough to see till it's too late, close all apps not working properly, volume a little low and distorted for ringtones and notifications.

With Android 10.

Twrp and vbmeta went on smoothly. Ui lags at times, browser and apps lag at times and ive had an app lag then flicker. The keyboard wouldnt go away even on the home screen once and ive had to do several reboots due to either lag or lockup. I dont know if this is due to twrp, magisk, or something else. Im still trying to find why so will be doing some more flashing.

Just wanted to give an update and if anyone is willing to test their device and report what you installed how you installed, your model and what bugs you experienced would be awesome in helping to write a smooth guide.

Custom rom

Please forgive my dumb questions. I'm kinda a novice in this but I have rooted my sony phone once following the descriptions given here. I just need clarity here before proceeding.

Thank you.

1. You said we will need to download a stock rom, please is it different from the one you posted the link here to download? [SamFirm_v0.5.0.zip

for the Samsung Galaxy A70(SM-A705FN), by MarvinMod]

2. I'm guessing it's also not the same with the lineage os

3. How do i unlock bootloader? Was the process added to your description?
[Samsung Galaxy A70 Guides, News, & Discussion] fizzingbees:
Samfirm 0.5.0 zip is a windows software that looks up and download the latest software for your exact Samsung A70 varient.

Once you have downloaded the firmware, only then you need to work with the provided files to root your phone.

Follow MarvinMod guide or other guides.

Read through entire thread for common problems and their solution
[Samsung Galaxy A70 Guides, News, & Discussion] Snarty_kuhl:
Thank you.

I saw another thread where it said one can root an A70 without having to factory reset, how true is that?
[Samsung Galaxy A70 Guides, News, & Discussion] Snarty_kuhl:
[MENTION=6698960]MarvinMod[/MENTION]

Please do I need to have an sd card or can i just copy magik to internal storage and load it from there?

[I don't have an sd card]
[Samsung Galaxy A70 Guides, News, & Discussion] mnlkm:
yeah i have laggy ui whats the reason
[Samsung Galaxy A70 Guides, News, & Discussion] fizzingbees:
Actually with Samsung and knox, our device storage gets encrypted. Also when you unlock bootloader you device by design gets factory reset

Factory reset is required for two reasons during root process

1) to disable encryption and its keys, allowing storage to be red properly instead of file names having random words and numbers

2) to prevent internet storage being shown as 15gb. Factory reset, properly partitions storage allowing full use of 118 gb internal storage.

You can try to root without factory reset, but if you encounter the above problems then know that factory reset might be required.

Backup your data just in case

---------- Post added at 08:31 PM ---------- Previous post was at 08:28 PM ----------

Umm. It's better to have the patched magisk zip on external storage. Can you attach a flash drive via OTG cable to your phone and work with that if you don't have microsd card

.

Reason being that you might need to factory reset your phone and internal storage data might get deleted.. In which case flash drive with otg or SD card might be convenient
[Samsung Galaxy A70 Guides, News, & Discussion] MarvinMod:
As long as magisk is installed after all the wipes then no, you wont need the sd card but i highly recommend you get one, even if its a 16gb sd.

[Samsung Galaxy A70 Guides, News, & Discussion] kac222:
Must go to recovery (TWRP or stock) and make wipe data,then reboot phone.
[Samsung Galaxy A70 Guides, News, & Discussion] fizzingbees:
Turn on developer mode

Turn on oem unlock

Reboot to download mode and there unlock bootloader.

You device will reset

After completing setup wizard.. Connect to internet and turn on developer settings and see if oem unlock is switched on and grayed out.

Only after this your bootloader is unlocked
[Samsung Galaxy A70 Guides, News, & Discussion] Snarty_kuhl:
Thanks to everyone that helped, I was able to unlock boatloader and found out that in the video he missed a step so I started it all over again and did it, and it works perfectly now. My phone is rooted, with stock android 10 and works very fine.

Rooting your phone does that.

This means google pay might not work on your phone.

I wanted to upgrade to 17.1 from 17 so I tried updating twrp and broke twrp somehow. Went back to stock, A705FNXXU3ASI2, and tried the way in the OP but twrp would not get past the splash screen. i tried older versions and they didn't work. Tried the whole process from the latest stock rom and still nothing.

I admit defeat.

SM- A705FN _ a705fnxxu5bth4_q

Great job my friend...thanks.:good::good:

i want to added this message on this session to help a little all guys to try to do this...

I tried 2 methods to my SM- A705FN , on first method

---- twrp, los17.1 and magisk root all gone well as you described on youtube video but the los17,1

don't like to me ( fingerprint not working,face recognition etc... :( ) so gone to second method

----magisk root and android 10

on this method is missing one step for fixing internal storage space (15gb or 32gb) to 128 so at ~ 10:00'' youtube video before install magisk you must do this step --->> wipe data --->>format (internal storage) --> reboot to---> recovery . and check if internal space is back to 128 gb if is ok gone to other steps install magisk etc.....

No you wont. Everything will be deleted except external sd. Before you begin, create a folder on your desktop and copy entire phones internal storage. Then you can restore internal by copying it back over when done.
