[Huawei P9 Lite Questions & Answers] Blazej222:
Hi. I have Huawei VNS-L21 phone with broken touchscreen. The phone works OK, I know the security pattern but unfortunately can't recover my contacts from phone memory since ADB access requires me to authorize it on the phone - I can't do that, because touchscreen doesn't work and OTG mouse/keyboard also doesn't work with this phone. Is there any way to force my way into phone's shell / force adb access without having to click anything on the phone itself?

Thanks in advance

Verizon 6800

ROM: DCD 3.2.0

Radio: 3.42.30

I've used multiple GPS apps so far such as HTC GPS Tool, GPS Viewer, etc and sometimes they see 1 sat, sometimes none. I live in Portland, OR .. there's definitely satellites above =)

I've let it scan for 30+ minutes.

I have gone through all the guides so far .. soft resets, turning on and off the GPS location, using astrogos loader before trying Google Maps, Navizon, Live Search, etc.

No dice.

Any ideas?
[Mogul, XV6800 ROM Development] viper8u2:
ever since I loaded this radio I have not been having luck getting gps locks either.

exact config as yours.

I also did the gps fix that GC posted

Would like to figure this out also
[Mogul, XV6800 ROM Development] spinaldex:
Well, if multiple people have the issue with this radio, maybe its a bunk release and we need to downgrade to something like 3.24.02.

I might try it later tonight if I get the chance.

Thats the release thread for the radio version we're on and people are obviously not having issues with it ... hmmmmm
[Mogul, XV6800 ROM Development] spinaldex:
Updates after more forum reading ...

I've done the GPS fix @: http://xdaforums.com/showthread.php?t=400975

I'm set to GPS Mode 2.

Still no locks.

Edit:

Another question ... if when using QPST you see that your 7500 modem is on COM5 vs where on most people's its on COM4, does that mean I should set the External GPS option on the phone to COM5 and start using that for everything going forward? I've tested both with no discernable difference in results testing .. but thought I should ask.
[Mogul, XV6800 ROM Development] daddymac117:
This may sound stupid, but have you been trying it outside or inside?

When I first tried to get a GPS lock back when I did the 2.1.0 flash, I tried in my room for hours. Sat it by my window, and the battery eventually drained trying to get a lock, with no luck.

Once I went outside, it was a completely different story. Even having the phone by a window wasn't good enough... I had to be outside to get any kind of GPS lock with it.
[Mogul, XV6800 ROM Development] spinaldex:
Issue resolved. Must have been something wrong with the radio firmware I used because I loaded another one and it worked.
[Mogul, XV6800 ROM Development] cleanser:
Would you mind sharing which radio revision worked for you?
[Mogul, XV6800 ROM Development] viper8u2:
i just did another update dialing #228 and option 2

After the reboot, I got a lock in less than 10 seconds. Might be a coincedence but oh well.

The gps in this is so sporadic, sometimes it locks immediately, most times it takes forever

[Mogul, XV6800 ROM Development] NotLutzik:
3.42.30 works good with sprint. Actually i get fastest lock out there out of all radios!
[Mogul, XV6800 ROM Development] gbenj:
if ur on sprint you should have run the sprint gps fix, which includes updating the spring pri. you should be getting locks in under 10 seconds.

you should also be very thankful that u arent on verizon like me and happy when u get a 3 minutes gps lock.

(sometimes takes me alot more)

i still havent decided if its a phone problem or a location thing.

I live in NYC, so wherever i go im surrounded by buildings...big ones, and lots of em, so im sure this has alot to do with my crappy gps times.

anyone out there on verizon in NYC who gets good locking times?

just wondering

thanks
[Mogul, XV6800 ROM Development] jamespaulritter:
I was in NYC for a week and never got my GPS to work the whole time I was there. Otherwise my GPS works fine.

[Upgrading, Modifying and Unlocking] funnzy:
Hey,

I bought a Mate 20 Pro. But it is not possible to unlock the bootloader, and they do not hand out the code anymore. Can you please suggest me a model which is open for development, has similar specs and can be connected via USB 3 to one or ideally two hdmi screens?
[Samsung Galaxy Tab A series Guides, News, & Discus] J.Michael:
What system do you use to manipulate the files? (Windows? Linux? Android?)

What is "overlay"? Do you extract the boot.img from the original AP.tar.md5, and from the magisk-patched.tar, copy the magisk-patched-boot.img to the beginning of the original-boot.img, and then replace the boot.img in magisk-patched.tar?

Do you give Odin four files, or just AP? Do you use CSC or HOME_CSC?
[Samsung Galaxy Tab A series Guides, News, & Discus] gcrutchr:
In answer to your question, basically, yes.

I only flash the 3 files in the .tar file

I am on a Windows 10 laptop. Only 3 files need to be modified by Magisk: boot.img, recovery.img, vbmeta.img

I use Hex Editor Neo for overlaying the modified kernel and recovery files..

At the end of these 2 stock files is code that needs to be there, thus the 65 MB file size.

So I open the stock .img files (boot, recovery) in Hex Editor Neo, and copy the modded boot, recovery code into each stock .img file..

I use cygwin to create the .tar file, then flash with ODIN 3.1.14
[Samsung Galaxy Tab A series Guides, News, & Discus] J.Michael:
Where does this leave you with respect to booting? Do you have to hold down buttons like you're trying to boot to recovery, then let go at the right time, to boot with Magisk active? Have you booted "normally" since you installed Magisk? Is Magisk still active? Have you shut down completely and then rebooted?

Wu's writeup says, when he's patching an AP file, to install to recovery, the boot.img is patched to "remove the signature of the image to prevent soft bricks". He doesn't explain why the signature would cause a soft brick with an unlocked bootloader and a nulled-out vbmeta. If you're restoring the original signature, it seems like you're flirting with the situation he was trying to avoid.

Will you be posting in the main Magisk thread. Aside from the news of another success, the details of your solution might help Wu improve the automatic patching enough to make manual adjustments unnecessary.
[Samsung Galaxy Tab A series Guides, News, & Discus] gcrutchr:
No keypress is required for booting to maintain root.

I have tried this multiple ways: shutdown/boot & reboot - still have root.

I have not posted in main Magisk thread yet. Can you give me a link to the main thread where I can post this information?
[Samsung Galaxy Tab A series Guides, News, & Discus] J.Michael:
https://xdaforums.com/apps/magisk/mod-magisk-v1-universal-systemless-t3432382

This is the General Discussion thread. I've seen references to github for reporting bugs. github might be a better bet for providing technical information about how patching should be implemented.
[Samsung Galaxy Tab A series Guides, News, & Discus] gcrutchr:
Thanks for the link. I have posted to the Magisk forum.
[Samsung Galaxy Tab A series Guides, News, & Discus] Gartrax:
Well, besides the possible outcomes, I tried the method and it worked for me. I'm not loosing magisk between boots too, not touching system apps but I can install modules and get root.

So, thank you very much for the finding!

You're welcome. Enjoy your Tab A now that you have root.
[Samsung Galaxy Tab A series Guides, News, & Discus] secretwolf98:
You must have a unlocked bootloader to proceed. How did you overlay the files?

In unlocking the bootloader, does it have any negative side? I remember on my sasung s5 before that i would loose what they call knox and not be able to restore permanently. How abiut in the 2019 tab?
[Samsung Galaxy Tab A series Guides, News, & Discus] gcrutchr:
Probably the same situation. I do not care about knox. I do not care about Samsun Pay.

I have not tested anything to restore knox.
[Samsung Galaxy Tab A series Guides, News, & Discus] secretwolf98:
Attempting to restore Knox would be a waste of time because it is impossible. When you think of Knox, think of the manufacture warranty. Once you void the warranty, it's a goner.
[Samsung Galaxy Tab A series Guides, News, & Discus] gcrutchr:
My understanding is knox is not installed on the T295
[Samsung Galaxy Tab A series Guides, News, & Discus] Alloc777:
According to the off site, the tablet has a Knox

Some user use the file from #1 and have this error(about security)

only official released binaries are allowed to be flashed after reboot

How I can solve the problem with "Only official released binaries are allowed to be flashed"?
[Samsung Galaxy Tab A series Guides, News, & Discus] gcrutchr:
Did you unlock bootloader?

Did you toggle OEM unlock in settings/developer options?
[Samsung Galaxy Tab A series Guides, News, & Discus] souzafl:
Friend thanks for responding ... Yes, the boot loader is unlocked. I have the tablet updated on version 10 (ZTO-T295XXU3BTFE) of android, and using version Odin 3.14.1 to update and install root. What is not clear to me are the files you provided with Root_T295XXU3BTFE_M20.4.tar. Do I need to install Root_T295XXU3BTFE_M20.4.tar (in place of the AP) along with version BL_T295XXS3ATB2_CL17034026_QB29519559_REV00_user_low_ship_MULTI_CERT.tar.md5, and the CP and HOME_CS files only?

After that, I enter recovery and do data cleaning?
[Samsung Galaxy Tab A series Guides, News, & Discus] gcrutchr:
I used someone elses instructions: how to build twrp without source.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Everything is easier than it seems! (c) If the bootloader is unlocked,then you need to select the Root_T295XXU3BTFE_M20.4.tar file in ODIN as part of the AP and the BL_T295XXS3ATB2 file as part of the BL and flash it. After downloading, update MagiskManager or install It if it is not available in the Apps. All, Root rights are obtained, but the data is saved. Simply use. :)
[Samsung Galaxy Tab A series Guides, News, & Discus] gcrutchr:
Just flash Root_T295XXU3BTFE_M20.4.tar.

[Samsung Galaxy Tab A series Guides, News, & Discus] alexbobspoons2:
Hi may I please ask, will this root work as well on a UK version of the T290 or T295?

Also, if the tablet were to come with android 10 could I move it back to 9 to be able to do this root?

Basically I want to buy this tablet for my little boy who has autism but I desperately need root and twrp as he has a habit of crashing tablets and breaking them too, so I need to be able to do a full exact-copy backup of the entire tablet so I can restore it fast (and maybe even to a spare tablet) but I need to be sure things will be stable and possible before I spend the money and before I give it to him.

Thank you so much for any help thank you.
[Samsung Galaxy Tab A series Guides, News, & Discus] Tianhe:
1) The method itself will work but you will need the corresponding patched file to achieve root for your specific firmware.

2) As long as bootloader version is same, you can switch between firmwares regardless of the version. Currently, on most regional variants, the bootloader version between latest Android 10 and the last Android 9 is same i.e. v3. Infact, its only due to this that we are able to achieve root on Android 10 firmware ( its a hack of sorts)

3) Although we have root, sadly we do not have any working TWRP. Its a work in progress and the test version cannot do a nadroid backup/restore. The only way to restore a bricked device is Odin flash.

Considering your requirements, i would say that this tablet isn't suitable for you at the moment.
[Samsung Galaxy Tab A series Guides, News, & Discus] alexbobspoons2:
Thank you very much I appreciate that. Any thoughts on a similar tablet that would fit, eg root and twrp? Thank you again

EDIT: Would I be able to get a similar level of backup using titanium backup rather than twrp I wonder??
[Samsung Galaxy Tab A series Guides, News, & Discus] Tianhe:
Many Samsung Tabs have official TWRP support and you can pick one based on your budget and regional availability. Visit the TWRP website to check out supported devices.

TiBu does backup app+data but it is nowhere near to the entire nandroid backup made by TWRP. And in my experience, restoring titanium backup gives errors when you shift between versions.
[Samsung Galaxy Tab A series Guides, News, & Discus] alexbobspoons2:
Thank you so much

EDIT: Looking on twrp the latest they have looks to be the 2018 version of the Tab A which is already a 2 year old tablet, which seems wasteful to buy. How long usually is it until a working twrp is established on a device? I see there is a separate thread working on it.

EDIT 2: How easy is a restore via Odin? Maybe I could root and use Odin to backup/restore instead of twrp??
[Samsung Galaxy Tab A series Guides, News, & Discus] temporarium:
I believe there may be a way of pulling whole partitions via ADB. Not sure if that could be used for device backup/restore. You may have to be in TWRP for that to work - to unmount the data partition, for example. Just a thought. Perhaps someone with more knowledge could clarify.
[Samsung Galaxy Tab A series Guides, News, & Discus] Tianhe:
No ETA for TWRP, depends on the device and the dev working on it. Samsung partitions are a bit weird so it might take time or we may never have a fully functional official TWRP. Since latest kernel sources are still missing, your guess is as good as mine !

Odin is like fastboot for Samsung; it doesnt require root but it cannot backup. Basically, its a flashing tool to flash firmware including modified/patched firmware.

In my limited experience, adb backup -all is extremely finicky, corrupts backup on Windows (maybe better on Linux) and the restore process is cumbersome.
[Samsung Galaxy Tab A series Guides, News, & Discus] alexbobspoons2:
Again thank you so much. Am I right then in thinking that there isnt really an existing way of backing up this particular tablet?? Thanks
[Samsung Galaxy Tab A series Guides, News, & Discus] Tianhe:
Right you are, no convenient way of backing up this tablet. But it's a work in progress and hope springs eternal !
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Make a backup of the Samsung Smart Switch Mobile to a memory card, this is the best option ... Well, something can be saved (data only) with the Hellium program, it can be restored after SSSM ...

When Hellium is launched for the first time on the device, a link is given to download the file for the computer, download, launch, enable USB debugging on the device and connect it to the computer, on the device we give the go-ahead on request ...

Hellium makes a backup to the built-in memory, so copy it to a memory card, and then back to restore ...

My Tab A is this one and this is what I did

First my Tab A is new and the first thing I did was unlock the bootloader, then with odin I put the files that said above the BL and the AP with the 2 files that they uploaded and I gave start and then restart my Tab A

With this you already have root? or did I skip a step? please help
[Samsung Galaxy Tab A series Guides, News, & Discus] Tianhe:
You skipped a very important part. After flashing, go directly to recovery and wipe data, then restart. DO NOT BOOT to system directly after flashing or you will not get root.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
What firmware version is installed? and what files were used to get Root rights?

The details of the process are important. After flashing the correct files and loading the device, there will be Root-rights, and the data will be saved :)

Does that mean you can find source for an earlier Android kernel?

Does TWRP need to be replaced every time the Android version changes?

---------- Post added at 11:21 ---------- Previous post was at 11:13 ----------

The option might be "androidboot.selinux=permissive". I've seen it in booting android-x86 on a PC.

To clarify: Are you able to specify kernel command line parameters? Are you sure they are not being overwritten/superceded by the bootloader?
[Samsung Galaxy Tab A series Guides, News, & Discus] Tianhe:
I believe Samsung released kernel sources for an earlier version on Samsung Open Source.
[Samsung Galaxy Tab A series Guides, News, & Discus] gcrutchr:
I tried that option. Does not work. Will check build log when get home to see commandline used during booting build process.

Install on a rooted device with Flashify or Official_TWRP_App ...

To install via ODIN, you need to resize to 64kB and pack it into a tar-archive, besides, if you install on a non-rooted device, you need a patched vbmeta file.
