[Fire TV Q&A, Help & Troubleshooting] saurabhshri:
It looks like like it indeed were messed up partitions. My initial plan was to flash GPT fix in DL mode (by @k4y0z : link). But I thought might as well play with few things if am anyway going to re-do everything.

I started by going deleting directories manually (e.g. `rm -rf /system`). My plan was to manually flash each partition through fastboot.

Before that I attempted

fastboot format all

and received a bunch of errors, specifically

Formatting is not supported for file system with type ''.

Though format didn't work, I decided to wipe anyway

fastboot -w

It finished with few errors, but looked like it created those directories which I deleted earlier. So I rebooted to TWRP and did

twrp wipe data

Re-flashed @0815hoffi 's image and luckily it booted into "Optimising storage" screen. Post boot-up it appears to be working OK so far. Had an issue with wifi, but restart fixed it.

tl;dr

rm -rf /cache
rm -rf /data/dalvik
rm -rf /system

fastboot format userdata # errors
fastboot -w # completed but some errors
twrp wipe data
twrp install <img.zip>
reboot

EDIT : Looks like @Sus_i and @racega went through a similar journey and ended up with a similar fix. Good to know the fix is reproducible. 😄 Here's their posts : https://xdaforums.com/t/unlock-root...ck-2nd-gen-tank.3907002/page-61#post-83031003
[Fire TV Q&A, Help & Troubleshooting] Bertonumber1:
Usually when this corrupted partitions happen you may try the command:

fastboot format userdata

followed by :

adb shell

(to call twrp#)

Then :

twrp wipe data

twrp wipe system

twrp wipe cache

twrp wipe dalvik

Then adb push the rom, gapps/magisk to /sdcard

twrp install nameofyourrom.zip

twrp install gappsxx.zip

Let it boot once and go back and update magisk via recovery.

(adb reboot recovery once permissions set or use powermenu little vic apk for quickness)

Another method I found which works good with fireos is :

When faced with corrupted/encrypted partition issues and/or unable to mount/format data issues

goto advanced wipe

select change file system

change it to EXT2

it will format data and data should appear become mount

hit back and change to EXT4 Filesystem again.

Then push rom and any other zips etc to /sdcard and install in usual way.

Good you got it working

Thank you for writing this down @Bertonumber1, I am sure it'll be very helpful to people who will encounter such situation in future. :)

I sincerely wish I could have done this. But I don't have an OTG with power input and deliveries are closed due to the pandemic. I was issuing TWRP commands through adb. I'll keep this in mind for future!

Thanks!
[Fire TV Q&A, Help & Troubleshooting] Bertonumber1:
Ah I see, I'm sure the twrp can be commanded to repair change file systems. However, you are correct it is much easier via otg mouse or keyboard.

Good evening,

I don't know if this is where you want it, but I'll just be crazy and try anyway! 🤪

I have no problems logging in on your website, but the app has been giving me network errors for a long time now. Also the login page just keeps "sending".

Need more info than what the ss gives you? Just ask! 🙂

Thank you for a great, educational project!

This is happening because you use the old XDA app, it is now abandoned.

@woodman is correct use the version on play store since that's the working version

[Samsung Galaxy Tab S7 / S7 Plus Questions & Answer] Almgrm2008:
I can't restore android in my tab s7 T-875 4G to old version

please help me
[Samsung Galaxy Tab S7 / S7 Plus Questions & Answer] LSS4181:
You won't be able to downgrade the normal way (via Odin) if you have upgraded to BUC1 or later.

Samsung incremented rollback protection at that point.

EDIT: The actual version number varies depending on model. It's the March security update, which I think for S7 (non-plus) would be BUC6.
[Samsung Galaxy Tab S7 / S7 Plus Questions & Answer] Almgrm2008:
Is it possible that there is no way to go back to an older version
[Samsung Galaxy Tab S7 / S7 Plus Questions & Answer] LSS4181:
If you're not rooted, well, there really is no way back without voiding your warranty.

If you're rooted (warranty already voided), you might be able to dd the individual partitions inside super (after extracting them using lpunpack), if you use Ian's TWRP. I only did this for getting GSI to work, and I did not test if it's possible to boot an earlier stock image this way post-increment.
[Samsung Galaxy Tab S7 / S7 Plus Questions & Answer] Almgrm2008:
Where can I find the Ian TWRP file for my device?
[Samsung Galaxy Tab S7 / S7 Plus Questions & Answer] LSS4181:
You may have to check the thread. Actually it's mainly for the S7 Plus (T976B).

From what I remember, back then there were few testers for the non-Plus S7 (T875) so the progress was limited at that time.

At present, it was reported to be working on T875, but the display were corrupted so you can only use the adb shell. I don't know how to make nandroid backups entirely from command line but for flashing the individual partitions via dd, the adb shell should be enough.
[Samsung Galaxy Tab S7 / S7 Plus Questions & Answer] Almgrm2008:
Did you explain to me how?
[Samsung Galaxy Tab S7 / S7 Plus Questions & Answer] LSS4181:
For TWRP I think you can just ask in the Telegram group (in Ian's TWRP thread).

I don't recommend flashing the stock Android 10 using the dd method, as I cannot assess what would be needed to get old Android 10 system working in your current state. In case there are some other rollback protections aside from the bootloader (I don't know), you risk bricking your device for good.

I've a thread in the guide section on how to flash GSI (credits to everyone who helped me getting everything working), and you can find how to use dd to flash system and vendor there. Again, it's only for GSI and I don't really think it's a good idea to flash older stock FW this way.

[Note 7 Accessories] BSFGP:
Guys, I need help. Where can I buy a motherboard for SM-N9300? I've been looking for the fourth day on the Internet...
[Samsung Galaxy Tab S3 Questions & Answers] gregchak:
I'm not a newbie to flashing ROMs but I am for flashing ROMs to my T820. I was following some instructions and something went horribly wrong. The ONLY thing I'm able to get into is the downloader (pwr+vol-dwn+home). I've gone through some threads about needing to re-flash stock image using Odin. So my question is, is re-falshing stock ROM the answer to this issue? And if so, where can I find a stock ROM for T820. I've looked through all kinds of threads and other sites looking for it and can't find it. I've tried using SamFirm but being as I can't get into my tablet I don't know the CSC/Region to use; and sidebar, it always says unauthorized anyway regardless of what region I put in the form. Does anyone have any advice to get me up and running? I started down this process because I had finally had it with the poor performance after a 2019 update and thought I'd try to give another ROM a try. Now I'd be happy to get back to my poor performing tablet.
[Samsung Galaxy Tab S3 Questions & Answers] bmwdroid:
Sorry to hear that.

A stock reflashing should help, but of course I can't guarantee that.

The original Samfirm isn't working any more.

You have to take samfirm_reborn0.3.6.2.

As you don't write where you're from I can't recommend a region.

Do you know this site: https://www.sammobile.com/samsung/galaxy-tab-s3/firmware/#SM-T820 as well?
[Samsung Galaxy Tab S3 Questions & Answers] gregchak:
I'm in USA. I didn't see anything on the SamsungMoblie.com site for USA. Any ideas what the region would be?

Appreciate the advice. I downloaded the version of SamFirm you linked and it does seem to work as expected using a known region value.
[Samsung Galaxy Tab S3 Questions & Answers] bmwdroid:
What about Canada?

US should be more like them imo ;)

Or cellular south I read somewhere might work as well.
[Samsung Galaxy Tab S3 Questions & Answers] gregchak:
Here's question, does it matter what CSC I use? I get it probably has implications for the cell version (T825 I think?), but for the wifi version is it needed? Could I use any English firmware? The only CSC codes I could find related to USA were ones bound to a carrier. I also found a few "unknown" CSC codes. Any idea what those are for?
[Samsung Galaxy Tab S3 Questions & Answers] bmwdroid:
@gregchak by searching the net for you I've found these two:

List of Samsung Galaxy CSC Country Specific Product code and region they belong to

List of CSC Country Specific code for Samsung Galaxy & various countries, regions, network carriers, model numbers, variants phone belong to.

www.androidsage.com

Samsung CSC Codes List For All Countries | iHax

Here is the complete Samsung CSC Codes list of all the regions and carriers. The Samsung Country Sepcific Codes list should help you identify the right firmware for your device.

ihax.io

In the past I thought like you that it doesn't matter, but I've realized after searching there are differences in Wifi frequencies/channels in the world.

idk how much the CSC interacts with Wifi.

So it might be ok, but idk exactly.

Btw doesn't it say anything on the T820 packing.
[Samsung Galaxy Tab S3 Questions & Answers] gregchak:
Unfortunately the packaging has long since been thrown out. I bought this tablet about 3-4 years ago. I tried a few different CSC codes that might work. XAR is apparently what worked for me. I was able to get that image installed via Odin and I'm back up and running. I really appreciate your help!

I followed the documentation I could find for getting the CSC from the settings app on my tablet but it says to look for it under Settings -> About Tablet -> Software Information -> Service Provider Software Version section. I don't have such a section. Also, being a tablet, I can't use the phone dialer method either. Do you know what the method is to get the CSC from settings? Or is there another way?
[Samsung Galaxy Tab S3 Questions & Answers] bmwdroid:
You could try PhoneINFOsam or HW info, but they need root what you probably don't have any longer, or do you?

Imo as you flashed XAR that should be its CSC (now)
[Samsung Galaxy Tab S3 Questions & Answers] bmwdroid:
@gregchak and I just found/remembered that:

Download mode shows your original Country code, no matter what CSC you flash

btw. it may be helpful for others if you edit your thread title and add "solved"
[Samsung Galaxy Tab S3 Questions & Answers] gregchak:
Good point about the title. I edited as you mentioned.

I tried booting into download mode but I don't see any CSC codes noted there. It looks like what I posted pics attached to my original post. The documentation I had read previously said that it is noted in download mode under the carrier section. But since my tablet is WiFi only I don't have a carrier section displayed in download mode.
[Samsung Galaxy Tab S3 Questions & Answers] bmwdroid:
@gregchak I suspected that, but it might have worked.

Another chance is the serial number perhaps.

But as there will be no more OTA updates published by Samsung it's not really necessary to know the former CSC.

Btw the app PhoneInfoSAM is telling me the original CSC on my WIFI P900.

[ASUS ROG Phone 5 / 5s] twistedumbrella:
Outside of China, you will have limited support for 5G. You won't have warranty coverage. You will pay additional to have it imported (although it may still be "cheaper" getting the less powerful version). That is all I can think of off the top of my head, but this is probably the 10th thread discussing the topic.
[ASUS ROG Phone 5 / 5s] ilovergb:
i dont have to pay any import fees since im buying this from within uk
[ASUS ROG Phone 5 / 5s] twistedumbrella:
The import fees are already calculated into the price.
[ASUS ROG Phone 5 / 5s] ilovergb:
You mentioned limited 5g support will this affect my connection to wifi or on mobile data ?
[ASUS ROG Phone 5 / 5s] twistedumbrella:
5G is mobile, but 4G will also be limited. The bands supported by a Chinese device outside of China are on the lower half of every tier (5G, 4G, 3G, etc.)

Honestly, you lose out on a lot of bandwidth if this is your main phone.
[ASUS ROG Phone 5 / 5s] Anubarak16:
Mostly mobile. It depends if there is even a 5g network in your country. For example in Germany this is not an issue because we don't have 5g and won't have it in the next 5 years with very little exceptions.

Here is the current map for the UK (check your provider) https://www.nperf.com/en/map/GB/-/314.O2/signal/?ll=52.146331432846786&lg=-1.9201904839901498&zoom=5
[ASUS ROG Phone 5 / 5s] chaos_envoys:
4g bands is limited too? Thats new for me... 😥
[ASUS ROG Phone 5 / 5s] twistedumbrella:
It's less noticeable because it's speed instead of coverage.
[ASUS ROG Phone 5 / 5s] ilovergb:
It will be my main phone can I expect frequent drop outs to connection and not be able to receive or make calls and text in certain areas of the country ?
[ASUS ROG Phone 5 / 5s] twistedumbrella:
Possibly. The difference with buying a supported phone is that you can complain to the carrier that you aren't getting reception and there will possibly be a fix. With an unsupported phone, there is little they can do about it.
[ASUS ROG Phone 5 / 5s] ilovergb:
Hmm I really want to try a tencent version with ww Rom to test it out but I don't know if I'll regret it
[ASUS ROG Phone 5 / 5s] twistedumbrella:
It sounds like you just want someone to tell you it isn't that bad, but the difference between fully functional and glorified tablet isn't enough to justify it.
[ASUS ROG Phone 5 / 5s] ilovergb:
True 🤣 but I could save a fair bit of money going this route I'm just trying to do as much reaserch as possible before pulling the trigger
[ASUS ROG Phone 5 / 5s] twistedumbrella:
The difference is £219.99 minus any shipping costs

no warranty (no free repairs after the return policy)

seller's customer service and return policy only

possible restocking fee if you change your mind

no 5G and slower than normal speeds for everything else

no OTA updates, updates may cause issues / errors

software that may not be properly installed

possibility that the bootloader cannot be unlocked
[ASUS ROG Phone 5 / 5s] ilovergb:
honestly the whole Tencent thing is a mess why are asus not doing anything about them being sold internationally ? surely they know this is an issue
[ASUS ROG Phone 5 / 5s] twistedumbrella:
It's not illegal. If I could sell you a device that you weren't going to return, wouldn't ever have serviced, and I would never have to provide any support for, it sounds like the best sale I've made.

Anyway, best of luck with the decision.
[ASUS ROG Phone 5 / 5s] ilovergb:
have you owned one or have one ?
[ASUS ROG Phone 5 / 5s] BILLYB187:
I did a lot of reading prior to deciding between official US and Tencent version, and ultimately went with the US version.

My main two reasons were 5g bands, and I was looking to avoid all the user issues people were having with the Tencent version. Among them updates was a priority for me. Although manual updates are easy to do, more users than I was comfortable with reported failed updates soft bricked devices etc. While they have been fairly easy to fix up till now, I was not willing to take the risk in the future. I don't think Asus would maliciously cripple a device, but they are clearly different and cross flashing FW has proven to be problematic.

Its your choice clearly, but I did not want to buy a device with that risk associated with it.
[ASUS ROG Phone 5 / 5s] ilovergb:
what are some of the issues that the TenCent ones face ? im still trying to decide I've also heard the internals are different to the official version
[ASUS ROG Phone 5 / 5s] chaos_envoys:
The internals are different? Thats another new thing for me.. I live in Indonesia and currently uses the Tencent version.. here we just started 5g, and it is only on 1 operator, so 5g isn't an issue, about 4g, the speed seems fine for me here. I can play Genshin and watch youtube with max resolution just fine using 4g..
[ASUS ROG Phone 5 / 5s] BILLYB187:
People have been having issues with Tencent phones flashed with WW firmware when they try to update. Fingerprint scanner has been problematic among other things. It would be a good idea to comb through the posts here and on zentalk in the rog phone 5 section.

The service/speed issues are consistently different for phones with proper FW compared to cross flashed devices.

As for the internals I can't really speak to that, as I have not seen any teardowns of the various versions or read anything about that anywhere else.

The savings is substantial, but so is the cost if you end up with a device that won't function the way you need/want it too. Again, personal choice for me was go official US version. If it was clear that cross flashing was the same as going official then clearly there would be no debate here but if you look, there are many topics demonstrating otherwise.

Either way you go good luck!
[ASUS ROG Phone 5 / 5s] ilovergb:
Yes I read it on zen talk about the internals being different I'm leaning towards the official version it just seems like there are way to many risks involved with tencent flashed
[ASUS ROG Phone 5 / 5s] BILLYB187:
It's too bad because I love that price point haha
[ASUS ROG Phone 5 / 5s] ilovergb:
Same it's very tempting to save the money but I don't think it will be worth the risk
[ASUS ROG Phone 5 / 5s] chaos_envoys:
How's your network coverage in US? It has all the 5g bands?
[ASUS ROG Phone 5 / 5s] kevin.chiha:
I live in Australia and I bought the tencent version with WW rom pre-flashed (assuming by the seller). So far having zero issues. Updated to latest verison manually and my 4G is working great. I don't give a damn about 5G so can't comment on that. As for different internals, that's news to me... Didn't notice anything at all yet. Happy with my purchase, it is proving to be worth the price difference so far.
[ASUS ROG Phone 5 / 5s] ilovergb:
Same it's very tempting to save the money but I don't think it will be worth the risk

How long have you had it ? That's really great that there's no issues but it doesn't mean you won't have them later
[ASUS ROG Phone 5 / 5s] kevin.chiha:
I've been using it for 2-3 weeks. Yep, issues might arise later but I'm hoping they won't. I can't really think of anything that might go wrong though. At least something that can't be fixed... We'll see, so far so good.

[ASUS ROG Phone 5 / 5s] BILLYB187:
I'm on ATT and in my area I don't have access to true 5G. I currently am able to access ATT 5GE service without issue, and the phone has the appropriate bands for my carrier.

Definitely look into your service providers band usage if you are concerned about service.
[ASUS ROG Phone 5 / 5s] chairman011:
I have both, just got the official version a couple of days ago. The Tencent version is thinner you can tell immediately. The official version grabs 5G from any network without any issues. The Tencent version only gets LTE I believe. No 5G in the United States. I heard T-Mobile now supports SA71 5g so I'm going to get the new SIM card and try it out on the Tencent version from what I understand is supports that band. We'll see.

Ive been on Tencet Version ROG 5 128/12GB for more than a month. It has WW Rom pre installed.
