No need to root to switch to another isp. get unlock code from current isp, install odin 3.14.1 and install any isp firmware you want from https://galaxyfirmware.com/model/SM-T307U/ I had an at&t branded with android9, and now i am running wind/freedom android11 firmware.
[Samsung Galaxy Tab A series Questions & Answers] AsItLies:
Hi, thnx for the useful info. Did you have trouble getting the unlock code from at&t? Where did you enter that code? A specific app on the at&t rom I'm guessing?

Getting a sprint version of this device, but want to use it t-mobile. Have read that just factory reset device and use odin to flash other firmware would work, does that sound feasible to you? I'm kind of doubting that but have no idea really.

It used to be flashing diff rom would sim unlock, but not anymore I don't think.

thnx for taking the time, so little info for this available.

cheers
[Samsung Galaxy Tab A series Questions & Answers] bbortnick:
No problem with at&t, although i had to impersonate a US location. Start here: https://www.att.com/deviceunlock/unlockstep1

Like I said, vendor unlock, install odin on your pc, use odin to install the desired firmware you downloaded.

The firmware should boot up, but maybe the radio bands are different between the two isp's? and therefore the LTE part of the tablet may not work. i don't care since I don't install a sim card, just use it on wifi.

Thanks a lot for the info guys. For anyone else reading, I used 'T307UVLS6CUH1' (BMC) - and it is unbranded and doesn't have a ton of bloatware.

Also, since there are so few users on this thing, will also drop that I made a stand for it here:

Galaxy Tab A Stand by xnappo

This is a horizontal stand for the Samsung Galaxy Tab A 8.4 (2020).Admittedly it is a bit specific because of the not-so-popular tablet and the use of a NetDot Gen10 magnetic USB cable. One could use this with USB-C directly - but I do really recommend that (likely stress on USB port).You will...

Hello,

I got unlocked ATT SM-T307UZNAATT from eBay.

My provider is Red Pocket, and I have ATT-compatible SIM.

When I try to place a call - ATT window appears and askes to log in to ATT account or create one.

How could I place calls?

Would appreciate any help!

How is the speed/lag? This tablet is mega slow, but I was wondering if I loaded different firmware (currently on AT&T) that it might help, since it can't be rooted.

My 8-yr old rooted Galaxy Tab S 8.4 is better than this thing, but alas a few apps won't run on 32-bit architecture. I think I will relegate this AT&T "brick" to my exercise bike for an entertainment interface.
[Samsung Galaxy Tab A series Questions & Answers] xnappo:
Meh - no better. It is pretty ridiculous - I was very happy with my 2015 Galaxy Tab S2 8.0 - but it started crashing all the time. This one is slower, thicker, lower resolution, and heavier! 32 GB really isn't enough storage either.

It is super annoying there are not any good 8 inch Android tablets. The Huawei M6 8.4 looks okay, but being in the US it is a bit of a pain to get.
[Samsung Galaxy Tab A series Questions & Answers] Kiyoshi.co.uk:
The only great 8" tablet is the Lenovo Legion Y700, running SD870 with 12gb ram. 2560x1600, but IPS and not OLED.

I own the Tab S 8.4 (2014), the Tab A 8.4 (2020) and the Y700 (2021, 8.8").

Tab A is terrible.

It's painfully slow.

It needs root.

It has the same RAM as a tablet 6 YEARS older than it, with LOWER resolution and ! much worse performance. I wish it could be fixed.... Android 10 Lineage is out for Tab S 8.4.
[Samsung Galaxy Tab A series Questions & Answers] K0mraid3:
I have done quite a few mods/tweaks to system/Global/Secure settings and also disabled Gaming Optimization Service (GOS) via Alliance Sheild X, it has made a MASSIVE difference. This device's (SM-T307U) performance is being HEAVILY limited by software-based restrictions. Most of which can be disabled without root. I can go into more detail as to how ive sped up this device if anyone is interested.

NOTE - If someone has the ATT version and can drop the .IMG or Firmware .zip that'd be awesome.

Ill keep trying to find a way to root this device until i get a new one, if anyone else has any success, DM me.
[Samsung Galaxy Tab A series Questions & Answers] kodiak799:
I've already deleted, turned-off and disabled everything I can. It's a good bit snappier, but still a dog.

I actually have 2, so I may play around with deleting/disabling apps via ADB. But it's not battery drain, which with some securetask special permissions I've gotten it to SIP power while the screen is off (varies, as low as 2% per day up to about 6-7%).

I checked the usual sources and couldn't find any AT&T image files.
[Samsung Galaxy Tab A series Questions & Answers] K0mraid3:
Yeah this this is good on power, it is just severely limited. Judging from similar devices with the same exynos processor, there's got to be something holding it back. I again recommend using SetEdit or something similar to modify some params in the settings tables. The line I highlighted is in both this tablet and my Galaxy S22 & S21. I also found a param in there called "Enhanced CPU responsiveness" which was set to off, after turning that on, I noticed a massive gain in my tablet.

Also worth noting is I added the line "Allow_more_heat_value" with a value of "30" and it allows all cores to boot to max.
[Samsung Galaxy Tab A series Questions & Answers] kodiak799:
I'll have to give this a shot. I wouldn't think AT&T throttled the CPU, which means Sammie did it for some reason. Probably to hit some sort of battery life benchmark. Or maybe it caused instability in some devices. But being a mid-tier processor you wouldn't expect that it needed to be throttled.

I believe Sammie is giving up on the Exynos processors. I bet they had issues on this tablet, said "screw it" and just **** this out with a throttled cpu.
[Samsung Galaxy Tab A series Questions & Answers] K0mraid3:
It's 100% a Samsung related throttle. From my understanding, it's done because they use many of the same parts/processors in various devices, so as a way to control device specific performances, they set limitations. For example, this tablet has the same processor as some of their other "Higher-end" models (if I'm not mistaken), so to keep this tablet from outperforming the others, it's limited. I'm sure there are other reasons, like the battery benchmark bit that you mentioned too.

But yeah. This is 100% a Samsung based throttling.
[Samsung Galaxy Tab A series Questions & Answers] Privateid:
I’d be interested in how you tweaked this tablet to function better.
[Samsung Galaxy Tab A series Questions & Answers] marubber:
Can you please share the mods/tweaks you've done?
[Samsung Galaxy Tab A series Questions & Answers] jarrnick:
I have one of these purely for its size, I travel over Europe and as the seating space is limited the smaller the better. I am running the Canadian Wind software but if anyone can give me a run through on disabling apps/services to speed up a bit that would be helpful.

I am going to buy the Lenovo Legion Y700 but only when a global version with LTE is available.

Cheers

Nick
[Samsung Galaxy Tab A series Questions & Answers] scarbutt11:
Just picked one of these up brand new for a great deal. Has anyone found any ways to speed it up a little bit?

Using as just a reading/video tablet.

Also I got a US Cellular one. Would it be prudent to flash an unlocked firmware? I'm not going to use it for LTE at all.
[Samsung Galaxy Tab A series Questions & Answers] Oiik:
hello !!

Anything about this tablet??
[Samsung Galaxy Tab A series Questions & Answers] xnappo:
Not really. Simply not enough storage space. Moving to SD doesn't help.

I finally bought a Lenovo Y700 and wish I had done so months ago. It is an awesome tablet, and the China ROM is actually no problem at all.
[Samsung Galaxy Tab A series Questions & Answers] bbortnick:
Can any of the setedit users please provide a little more detail to us?

I have installed Settings Database Editor from Netvor; it seems sketchy, as it requires you to sideload an apk called providor package to actually change the settings.

I have also installed Alliance Shield X, which requires you to delate all your accounts and make it the owner of your device, which also seems sketchy

Can anyone provide more details on the safety of these apps?
[Samsung Galaxy Tab A series Questions & Answers] bbortnick:
I ended up installing f-droid setedit and changed/added the three variables. I did not notice any change in performance. It's still pokey. Why can't Samsung just make a v2 of this tablet, wouldn't cost much to (re)engineer. Clearly there is a market for decent performing 8" tablets.
[Samsung Galaxy Tab A series Questions & Answers] Old_Mil:
I did the setedit changes and it's a little faster.

It would really be nice to be able to root the thing and purge the bloat.

[Samsung Galaxy S9+ Questions & Answers] litlmike:
I rebooted my S9+ and now it won't turn on. I tried pressing and holding the power button and down volume key as well and nothing works. I tried charging the phone and nothing works. I tried replacing the battery and nothing works. Do you have any suggestions? Device is factory and not rooted.
[Samsung Galaxy S9+ Questions & Answers] blackhawk:
Did it indicate it was charging?

Power switch failure?
[Samsung Galaxy S9+ Questions & Answers] litlmike:
It did not indicate it was charging. I think it is possible that it is a power switch failure. Is there a way to test that?
[Samsung Galaxy S9+ Questions & Answers] blackhawk:
If it's not indicating a charge, and the battery has enough of a charge to boot... it's DOA.

Sounds like a mobo failure. Sorry.

Check for a displaced ribbon cable connection and evidence of a fried component(s).

Not sure if a charge port pcb failure could cause this or not.
[Samsung Galaxy S9+ Questions & Answers] litlmike:
If it is a mobo failure, is there a way to get the data from the internal storage still? Is the internal hard drive on the mobo?
[Samsung Galaxy S9+ Questions & Answers] blackhawk:
My thoughts, maybe correct or not...

There's probably a way to directly access the internal memory at a test point on the mobo but that's getting into some intense data recovery.

If the circuit is damaged in such a way that the test point isn't functional* (if it exists) then the chipset would need to be desoldered and put in a test rig or another mobo to access it... if the chipset itself wasn't fried (and didn't get damaged or corrupted in the process).

That's a lot of if's... and probably not something you want to pay an expert to >try< and do.

You can contact the manufacturer and see what they say.

If you can connect to a PC via ADB or find/repair the damage that's about your only shot.

Much easier to always backup your critical data redundantly beforehand... lightning strikes fast and unpredictably.

*or repair the damaged mobo or whatever failed
[Samsung Galaxy S9+ Questions & Answers] litlmike:
If I wanted to pay for someone to revive this device or even just grab the data from it, where could I take the device? Does a regular repair shop do this kind of work?
[Samsung Galaxy S9+ Questions & Answers] blackhawk:
The best you can find. The data is probably toast unless it's an easy fix otherwise you have no easy way to access the memory.

Try what I stated before... it will be a journey.

The reason I backup my data, redundantly, is because I have lost entire databases. Consider it a lesson from the University of Hard Knocks if you can't recover it.
[Samsung Galaxy S9+ Questions & Answers] MichalPlays:
Hey, I found a solution for this problem.

I had same problem with my s9+ but it sometimes turned on but stayed at 0% battery charge for hours.

I used an wireless charger from Anker, put my s9+ there and waited for a hour.

After an hour, the phone automatically booted with 5% battery charge.

Maybe this will work for you too. Grab one of those Anker stands from Amazon if you have prime subscription, use it to charge the phone and then after restoring your data, just return the charger and I would recommend to replace the battery. You know, the s9+ is quite old by now and since it's an non-removable battery, it's better to do it now than experience the same story again.

Ok I'm at my end with this convert to global I just can't get it done without error or crashdump. I've been flashing since g1 but this is wuppin my ass. This phone (in2017) is literally unusable on anything except T-Mobile. I've tried it on mint mobile and google Fi and it's the same every time. What I'm offering is $50 to whomever can successfuly remote flash and convert my device to the global software. It's extreme I guess but I need a working device. Thanks all
[OnePlus 8 Questions & Answers] Nathan.7118391:
No need for the money. This is what I did because it didn't work for me after A11 upgraded on TMO. Here's what I do

1. MSM back to stock (I have the 10.5.7 TMO version).

2. No wifi, no sign and no mobile data. Just skip until you get normal screen.

3. In developer options toggle on oem unlock, usb debugging ( I assume you know how to get developer options).

4. In fastboot type command fastboot flash cust-unlock unlock_code.bin (This should say okay and then okay once hit return)

5. Then type fastboot oem unlock (on your phone verify unlock)

6. When the phone boots run through set up (no wifi, no e-mail, no mobile data.

7. Developer options - usb debugging

8. Download the firmware from the global thread. (Do the one with global (i have the 10.5.10 global [ this one is the 15.O.19 global one]))

9. Put your phone in bootloader mode

10. Unzip the firware and run the fashall.bat file.

BOOMSHAKALAKA! Happy modding!
[OnePlus 8 Questions & Answers] Justin credible:
Cool thanks man. I'm gonna give it a go one more time and see what happens. Also when its in bootloader mode what exactly should it show up as in device manager? Depending on the driver I've seen Kedacom or LeMobile, also Google Inc or IN2017. **** one time it showed as IN2023 not sure why. It needs to show specifically as ____?
[OnePlus 8 Questions & Answers] Nathan.7118391:
You know what, I never checked device manager. Follow the MSM thread and then follow the upgrade to global thread and you'll be fine. Just remember to use the A10 firmware. For some reason the A11 didn't work for me. Happy modding!
[OnePlus 8 Questions & Answers] Justin credible:
Hey man i wanted to say thank you and i very much mean it. The instructions you put up top should be written again and stickied in the guides section because this is what finally got the in2017 converted. my phone actually rings when people call and i can even dial out now. thanks again bro!!!

I have rooted my mobile, and safteynet is success, Device is also showing certified in play store settings but i'm unable to update google play system update in security status in settings.

Its showing update available but when I try to do it, asks me to reboot to complete the installation and when I do so it reboots twice and update doesn't happens. Currently its on April 1, 2021.
[Xiaomi Poco X3 Pro] pl1992aw:
Screenshots? (Make it English, I don't understand Hindi)

I don't really get what you mean.

Security update is not through Playstore.

The ROM provider has to update it.

My bad, I'm out-dated.

MIUI OTA update cannot be done when you have root.

Play service should be auto-updated.

Did you try uninstall Magisk, reboot and see if it can update?

I found some reddit having same issues. They had miui 12 android 10.

https://www.reddit.com/r/Xiaomi/comments/khkf3c

If you don't want to uninstall Magisk or factory reset, you can try as here:

https://xdaforums.com/t/how-to-upda...ate-manually-on-any-android-phone-10.4197723/

If you had uninstall Magisk, reboot, but it still cannot update, then you might need to try factory reset.

If factory reset and no magisk installed still won't have this Google Play system update installed, then it's MIUI's fault.
[Xiaomi Poco X3 Pro] stunned:
April might be the latest available. I just checked and had March update and after update and restart it is now April and doesn't offer updates
[Xiaomi Poco X3 Pro] RavzsTez:
A) I tried this app already, it just changes the date and that too without any reboot. If we download update from phone it requires reboot where as this app just installed and date changed and app disappeared without reboot. Previously it was march, after installing it went to April but still the same update is showing.

B) Uninstalling magisk means just removing the app or complete unrooting the device?
[Xiaomi Poco X3 Pro] pl1992aw:
I checked the security update in ArrowOS, it's on May 5th, so there's sure an update.

A) I checked the app on that website I provided, and they had only the April update, so you don't find anything changing.

B) I mean unrooting. Removing the app only but there's still something modified in the boot partition by Magisk.
[Xiaomi Poco X3 Pro] RavzsTez:
So unrooting and updating is the only option, but if I unroot then device shows not certified and not able to login into any google services and hence cant update that also
[Xiaomi Poco X3 Pro] pl1992aw:
If unrooting is problematic for you, then stay with the April 1st security.

Until the apk website provide a newer update, then you can use it.

Or maybe you can ask ArrowOS if they have an APK for you to install it manually.
[Xiaomi Poco X3 Pro] RavzsTez:
Thank for clearing my doubt
[Xiaomi Poco X3 Pro] pl1992aw:
There's Magisk update, v23.0.

Before try flashing MIUI by Xiaomi.eu, you can try Magisk v23.0 and see if it will allow the security update, maybe it will work.

If you are already on Magisk v23.0, then ignore this reply.
[Xiaomi Poco X3 Pro] RavzsTez:
I'm already on v23 , and even I thought the same thing like u said to try Xiaomi.eu.

But I have some doubts on that rom

1- can I get ota updates

2- should I have stock recovery or twrp for updating ota

3- consider after installing ota will the custom recovery be gone?

4- This EU rom installing for first time on X3 pro, can I install using twrp or I need flash tool and EU fastboot rom?

5- currently any custom recovery is not able to read internal files when I'm in recovery mode, why is this so? Is it my issue or for everyone?

6- If point 6 is true then how to install the rom? Even if I place rom in root folder it's not showing in recovery

7- if I get ota then is it just the update I receive or complete rom file I need to download again?

8- will I need to format everytime for every ota update?
[Xiaomi Poco X3 Pro] pl1992aw:
Thought of another way to try.

Press the "download & install" in security update.

You said then it tells you to reboot. Don't reboot yet.

Go into Magisk and uninstall Magisk.

After Magisk said it's uninstalled, then you press reboot.

So you get the system planned to install the security update after reboot, and have Magisk uninstalled.

See if this helps.
[Xiaomi Poco X3 Pro] xelrix:
1. Yes you'll get ota

2. Stay with twrp

3. Twrp stays

4. You can install miui eu with twrp but may requires format data. You could try dirty flash but expect issues

5. Yes it's normal because of data encryption. Not just you. But the latest twrp by nebrassy can decrypt and mount data properly

6. You can use sd card or otg

7. Updater handles it

8. No unless specifically being told to
[Xiaomi Poco X3 Pro] RavzsTez:
I'll try this but, I want to flash EU rom and try it out
[Xiaomi Poco X3 Pro] RavzsTez:
So EU rom has inbuilt custom recovery? If so what is the name of recovery it has?

Also will the device be certified without rooting? like pass safteynet and google services able to login?

I'm currently on nebrassy recovery , but still unable to read system files when I'm in recovery mode
[Xiaomi Poco X3 Pro] xelrix:
No it doesn't have its own custom recovery.

Yes it will be certified oob.

Try setting up a pin code. On start up, it would attempt to decrypt by asking you to put in pin code.
[Xiaomi Poco X3 Pro] RavzsTez:
Or should i use Disable Force encryption? Will there be any issue if i use that?

Also please share the file
[Xiaomi Poco X3 Pro] RavzsTez:
Currently which custom recovery is better for installing custom Rom?
[Xiaomi Poco X3 Pro] pl1992aw:
TWRP and OrangeFox.

TWRP can decrypt data partition, OrangeFox cannot.

OrangeFox can format data partition without issue, but TWRP may have problem after formatting data.

Download both on your PC in case you encounter some problem with either one.
[Xiaomi Poco X3 Pro] RavzsTez:
So TWRP may have problem after formatting data so ill try this for .EU ROM
