Team Win Recovery Project (TWRP) is an open-source software custom recovery image for Android-based devices. It provides a touchscreen-enabled interface that allows users to install third-party firmware and back up the current system, functions often unsupported by stock recovery images. It is, therefore, often installed when rooting Android devices, although it isn't dependent on a device being rooted to be installed.

Downloads:

TWRP 3.3.x

Please Install Via Odin!

Disabling Force Encryption(Highly recommended)

This process involves wiping your data

- flash twrp on your current rom

- Click Wipe and then click format data(Wipes your /sdcard as well)

- Go to download mode and flash stock

- Make sure to to not let it boot and reboot to download mode again(Power + Vol Up + Vol Down + USB cable)

- Flash TWRP again and boot to recovery(Power + Vol Up + USB Cable)

Not so quick, it does not work on mine. When I flash twrp in odin it tells me that it is unverified package on tablet and odin says failed. Anyway, could anyone share a patched bootloader? I have the latest rom ...... June.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] rupanshji:
Unlock your bootloader m8
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] vq8acsxht:
No the bootloader was unlocked. I finally was able to flash twrp. You missed a step though:

0) Reflash all the OEM First before flashing TWRP

Just a heads up to anyone else....

If you get this message in red text:

"Only official released binaries are allowed to be flashed"

or this message in a blue screen of death:

"Security Error: This device has been flashed with unauthorized software & is locked. Call your mobile operator for additional support. Please note that repair/return for this issue may have additional cost."

Congradulations! You just tripped SAMSUNG'S SECURITY APE! You just won..... more flashing.... :silly:

Just reflash "ALL OF THE STOCK FIRMWARE." The BL + AP + CP + CSC to fix it and put the ape back into the cage.

Here is the command to push a file to the SD card with ADB:

adb push Disable_DM-Verity.zip /sdcard/Disable_DM-Verity.zip

Thanks rupanshji !!!! Hope you get encryption working soon and LOS.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] koobie777:
I can confirm that it is working on SM-T597P with firmware T597PVPS2ASG3. I also went ahead and pulled the stock recovery and boot, as well as modified the RootFix for any device. You can find those files here Link. Thanks Dev for bringing this to light :D. I also didn't follow the install directions exactly so ill list the steps i took.

1. Flash TWRP with modded odin and reboot to download.

2. Flash Stock recovery and as soon as it reboots enter stock recovery.

3. Wipe Data/Factory Reset.

4. Reboot to Bootloader from Stock Recovery.

5. Flash TWRP again and after reboot enter TWRP.

6. Flash RootFix.

7. Flash DM-Verity and Force Encryption Disabler.

8. Reboot to system.

If anyone would like me to pull the stock recovery of their firmware for them i'm more than happy to.

Setting up XDA Ad-free

Here is one possible reason there may be 'so few with xda ad-free' - as a new member of xdadevelopers forums, I initially found it difficult to find out: (i) how to send feedback about Pixel Dust OS for my Pixel (said to be welcomed), (ii) how to post questions and maybe add some helpful information about OTA updates in the right forum (partly to see how xda worked before paying for xda ad-free), and (iii) how to obtain and pay for xda ad-free. I almost gave up, but I think I have done it now (fingers crossed).
[Nook Touch General] MildBill:
OK, so I had a good idea, and did it badly...

I have a many-years old Nook Simple Touch (NST1 hereafter), which I had partitioned for more space to sideload. I decided a while back to simply load everything on a micro-SD card, which I did. I started having issues with NST1, so I purchased another (refurbed) Nook Simple Touch (NST2 hereatfer). I started looking for the info to undo the partitioning change, and came across info to backup and restore that involved deleting the partitions, and thus the restore process would rewrite them.

AH HAH! So, I figured I could backup the NST2, which was fresh, and restore it to NST1. Worked like a charm, too.

Now we come to the problem... It also overwrote both the serial number, which I have no way to get back that I can find, and overwrote the MAC address of NST1. The original MAC address I do have, if I knew where to put it. And, if there's a way to find the original serial number, that too would be good to put back.

So, there you have it. Anybody got any ideas? I'm sure someone, probably many someones here, know where this data is recorded on the NST, and the easiest way to modify the data so it reflects the original information. I'm also hoping that someone can give me ideas on how to find the original serial number again. (Yes, I know it is written on the case where the micro-SD card goes in, but over the years that has become mostly unreadable, so that's out.)

Thanks muchly for any help you can offer,

MildBill
[Nook Touch General] nmyshkin:
You can find the serial number on the edge of the NST, hidden behind the SD card "door".

As to the rest, you may be SOL. There are places on the device where the S/N and MAC address are stored as strings, but I think the actual information is stored more deeply and may be encrypted with keys. Still, can't hurt to scour the forum. I could be wrong.
[Nook Touch General] MildBill:
As I stated in the OP, that data is no longer readable, after many years of use. I have the MAC address (did you *read* the post??) I need to know where to put it!
[Nook Touch General] nmyshkin:
Yeah, I missed that last part. Search on "serial number" and you'll find a dev discussion about this. Unless you have a copy of the original ROM partition I don't think you can do anything.
[Nook Touch General] MildBill:
Surely there is some way to insert/change the existing data to reflect the original. And, no, sadly, stupidly, I did not back up that data, I had forgotten it was coded in flash, and knew I was going to overwrite the entire device.
[Nook Touch General] Renate:
It's been a while since I worked on NSTs.

On the iMX6 (Glows), the serial number is in two places:

In mmcblk0 at offset 200 it says "SN-12345667890123456", I believe purely as informational.

In mmcblk0 at offset 80400 is an XML structure with the SN used by Android.

On the OMAP3 (NST), the serial number is in two places:

/rom/devconf/DeviceID (16 bytes ASCII)

/rom/devconf/SerialNumber (16 bytes ASCII)

/rom is normally mounted r/w so you can just write these and reboot.
[Nook Touch General] MildBill:
Bless you Renate, I knew you would know! How about the location of the MAC address?? This appears to also be software coded somewhere, as when I was finished with the process outlined above, both devices have the same MAC address.
[Nook Touch General] Renate:
# cd /rom/devconf
# echo -n 1234567890123456 > DeviceID
# echo -n 1234567890123456 > SerialNumber
# echo -n 123456789012 > MACAddress
[Nook Touch General] MildBill:
Renate,

Yes, I have successfully deciphered (mostly) the serial number/device ID printed on the case near the micro-SD slot. I had to guess a couple of numbers but I think I got them right.

And, I saw the MAC address file as pointed out, BUT, I changed that as well, maintaining the format involved, and when restarted the device info said 'Unavailable' for the MAC address, until I turned WiFi on, and then that reverted to the wrong address, as written from the other device. I'm assuming that there is some other place where it is stored in some form. Any ideas on that?

MildBill

P.S. Actually, I edited the files with a Windows editor, the serial/device ID change worked fine as far as I can see.

P.P.S. On further check, while the Device Info:About Your Nook shows the 'cloned' MAC address after turning WiFi on, the MAC Address file still reflects the original address (obtained from a separate source from prior to the whole business.
[Nook Touch General] nmyshkin:
Read this thread

https://xdaforums.com/showthread.php?t=1480974
[Nook Touch General] Renate:
Yeah, the initialization of the WiFi adapter is in /rom/devconf/WiFiBackupCalibration.

It's a series of register addresses/counts and data.

The MAC is in reverse order in hex, not ASCII.

0x00 - 0x01
0x01 - 0x6d
0x02 - 0x54
0x03 - 6th byte MAC
0x04 - 5th byte MAC
0x05 - 4th byte MAC
0x06 - 3rd byte MAC
0x07 - 0x01
0x08 - 0x71
0x09 - 0x54
0x0a - 2nd byte MAC
0x0b - 1st byte MAC
[Nook Touch General] MildBill:
OK, I have decided to change directions...

After getting all the data changed, I tried to erase and deregister, then register again, and it gives me errors.

All the data, by the way, as well as the Main Board SN are on a sticker ON the motherboard, so I know I got them right. There are, however other bits of data not there, which no doubt need to all match up, and don't. So, I have decided this can be a test device for some of the various rooted ROMs, and other goodies out there, to see if any of them are worthwhile to use. If not, I will simple restore the NST2 backup to it, and simply make sure I don't have both of them powered up and online at the same time.

Thanks to all for trying to help, even if it didn't work out. The new (to me) device will last me for many more years I'm sure.

MildBill
[Nook Touch General] nmyshkin:
Yes, I'm sure you noticed in the link I posted above that you will not be able to register the device. The original info is stored and processed with keys and these are used when communicating with B&N.

You may have missed the link within the link: http://xdaforums.com/showthread.php?t=892426

This may allow you to fix the MAC address issue. Seems to have worked for others.

So the really big issue is then how to overcome the rapid battery drain of an unregistered NST. I tried many things when I got my second NST but was never able to find something that didn't just make things worse. A truly B&N-free NST is a really worthy goal, but only if the battery issue can be solved. It seems like every attempt to disable/delete parts of the B&N system sets up a constantly running panic in the system background. The same appears to be true if you skip OOBE.

Advice: do a reset, try the MAC fix. If it works, do a backup. That's your baseline.

Good luck.

Edit: I can confirm that the method described in the link above does seem to successfully spoof the MAC address, as least as far as my router is concerned. I used an online hex editor to make the changes on a copy of the /rom/devconf/WiFiBackupCalibration file and then copied it back to my NST and rebooted. Initially in my Nook Settings app the MAC address shows up as "unknown", but this seems to be true at every reboot. Once a WiFi connection is made, the spoofed address is shown by the router and it even shows up in the Settings app thereafter without any additional changes.
[Samsung Galaxy A50 Questions & Answers] occams-razor:
Does anybody know if I can use Odin to put stock Sprint A505U firmware into my Verizon A505U? There's no OEM unlock option on the A505U (US version) phone so the bootloader is locked. I prefer not to root so I can use google-pay without any masking shenanigans.

The sprint firmware has a different set of enabled FDD-LTE bands that makes it more useful. Thanks.

Edit:

I've just learned that some carrier unlocked galaxies s8, s9, s10, etc. running pie will auto rebrand and adjust available bands to adapt to whatever Sim is installed. Does the A505U do this? This would be far easier than flashing if it works for the A505U.
[Samsung Galaxy A50 Questions & Answers] cominteldb:
The Samsung BYOD rebranding feature for U models based on sim insertion is always released about 10 months after the phone's initial release.

This has been the case for S8, Note 8, S9, and Note 9. It is not even released yet for S10.

So it will probably be getting close to mid-2020 before it is released for A505U, if even then.
[Samsung Galaxy A50 Questions & Answers] occams-razor:
Thanks for the response. I am still trying to wrap my head around how Samsung does their "BYOD Experience" rebranding. It appears that Samsung has gone the route of common hardware for US phones while supporting all the major carrier CSC's (multi-CSC?) within a given branded firmware .

Since only the CDMA carriers Xfinity, Sprint, and Verizon have the A505U, I'll try to find somebody with an ATT or TMO sim to see how my supposedly unlocked Verizon A505U reacts. I haven't seen any reports of what happens posted yet as it relates to the A505U.
[Samsung Galaxy A50 Questions & Answers] Xplorer4x4:
I have a Galaxy A505U through Sprint. As you've said it is bootloader locked by the carrier. The 7 day trick does not work to show/enable Oem Unlock. I forget the reason now but I have reflashed stock firmware in Odin before which would modify system partion despite a locked bootloader. So I believe that you could in theory flash the sprint firmware in odion but I don't know how this will affect coverage. I do know sprint has roaming agreement in place with vzw so it should work.... But you're coverage may be degraded as I believe it's not going to support all of vzw lte bands... On a slightly separate note I am curious if there's some way to get around the lock using Odin. I am rusty on my Samsung modding(not eisnce sgs4) and terminology but I'm wondering if we could flash just the bootloader itself from another variant.
[Samsung Galaxy A50 Questions & Answers] elliwigy:
this is not accurate.. the devices contain multi csc in the omc partition so once the device is sim unlocked all the firmwares for usa variants have the csc for all the carriers.. you can use an app like phoneinfo and see the available csc's.. it has been this way as you stated since the S8 and up...

now if you are talking about U1 devices then thats a different story.. U1 devices typically have the same csc's but are just unbranded meaning little to no carrier bloat for example.

this is typically why all the firmwares are interchangeable because they are all containing the same csc. The only difference sometimes will be the userdata which might b labeled specific to a carrier but ultimately this doesnt matter either as they typically would contain only a few extra carrier bloat apps that shouldnt impact overall function at all..

heck, if you know what ur doing you can even change the csc code without even flashing any other firmware or putting another sim in.. i typically for example use sprint sales code with vzw network code bcuz i have verizon but sprint has more dialer codes..

as an example my g975u was purchased from verizon but i currently set the csc to GCF for research purposes and all my vzw services work great and to start I used a U firmware that had userdata labeled for SPR lol I also removed the last bit in the carrier code for research purposes.. when i toss a tmo sim in it automatically loads the apns and carrier mode for tmo and it just works without even rebooting
[Samsung Galaxy A50 Questions & Answers] elliwigy:
you are correct.. the usa variants are multi csc so they should work anywhere.. international devices also contain multi csc for w.e region it is purchased in. once sim unlocked if u say try to take ur phone to china or something ur device wont contain that csc but you should be able to get it to work with apn edits for example and might not have all the bells and whistles since couldnt flash their specific csc if that makes sense..

These phones nowadays are all world capable for the most part and contain the hardware to work on the differet networks (cdma gsm etc)

Samsungs "byod" experience just means its carrier unbranded so its sim unlocked out the box and can b used on any usa network without all the carrier bloat.. this is sort of pointless in my opinion since usually these firmwares can also b flashed to carrier branded variants..

on a side note, i have a tmo sim but mainly i use verizon and am getting an A50 from big red tomorrow so I will test this out for u and let u kno how tmo is in a vzw a50.

i have a tmo purchased a10e and my vzw sim works great in it.. in fact, vzw works better in the tmo phone than tmo haha but thats bcuz tmo isnt as good service wise in my area
[Samsung Galaxy A50 Questions & Answers] occams-razor:
Thanks for the great info! Please let us know how the TMO sim works out. I'm most curious about whether TMO features like their VoLTE and VoWIFI are enabled.

An Interested Observer...

Hello.. :cool:

Your comment sparked my interest.. as I'm a new owner of the Xfinity variant of the Galaxy A50.

Although I have no plans to leave Xfinity for the remainder of 2019.. as I'm waiting for my $250.00 Promo Rebate which comes around the 4th Month of service to cover just under 65% of my investment in the A50... leaving me with a $135.00 balance.. But, if what you state is indeed the case.. and these devices have the guts to run on traditional GSM Carrier's.. this add much more intrigue into the equation..:angel:

I'm not one to pry.. but, did you follow through with your purchase? and if so... what were your findings?
[Samsung Galaxy A50 Questions & Answers] Xplorer4x4:
That is correct but as someone who works in the industry and works with 3 out of 4 nationwide carriers I can say Att typically has there iphones manufacturered without a cdma attena making it gsm only.

I just checked my sprint A505U and it does have csc codes for many carriers including att, spt, vzw and t-mob among others. So generally another firmware should work fine then?

[Windows Mobile Development and Hacking General] kwoodall:
I have a programming question for all you out there...

Where can I find information on how to add a new item to the menu for Contact Manager? Either in the menu where you can select a profile to edit or in the menu during profile editing.

I know this can be done since SIM Manager and Google Maps add links in the first menu, but the programmer I'm working with doesn't know how!

Thanks!
