Thanks but no thanks
I don't understand chinese
Anybody want to help me? Please

Download this file http://preview.tinyurl.com/z3wwuyp. ( patched file)
Save to an easy located place.
Connect your computer to the tablet and start fastboot(volume up and down together and power button)should show fastboot starting.
Open a CMD window on your computer and type cd c:\ to get to just a c prompt.
Then type fastboot flash ESP This bit then should read the full location of the unzipped file that is patched.
An example like mine is fastboot flash ESP c:/adb/1050f-esp-patched.img , this is how I did mine and I have an unlocked bootloader and permanent TWRP

So this actually unlocks the BL? How many users have test-tried this and can confirm?

They do work, I can confirm
The files were originally made by ionioni and workdowg i believe and they work!! All the tutorials have been deleted for some reason so now all the rest of the users are either stuck at a boot screen or cant upgrade (like me).
 @corasman was bright enough to capture some of the files. He has saved my bacon at least for now.
Again, @all on lollipop - if you are stuck at a loop or cant upgrade flash the files in this post

So they work, but there's no proper tutorials to ensure that things are done properly, is what you're saying?
Also, the deletion/closing of those threads is baffling. Does anybody know the reason? Maybe the moderators can chime in.

I believe XDA rules say something about source code for files must be open source,and if I have read right ionioni infringed the rules.

In this thread . /general/flash-phone-flash-tools-t3307272. I messed up my system and ionioni really helped me out,maybe people can read enough to rescue their systems.

No probs Adrian dude... Thanks again...
Well for the tutorials, the original threads maybe closed but there is still valuable info there.
I read the first 15 pages of the boot-loader thread and realised I need a stock boot-loader as it kept coming up error when trying to installing the latest 256 update.
Hope all that are in peril recover quickly now

At the moment I am sticking with KitKat until a modified ROM is hopefully produced.
Changed my mind,
I now have full unlocked bootloader and TWRP with the latest upgrade.

do you have these files for 830LC?

Sorry No
I think someone said the file worked for their 8 inch one but the DPI was different.

I might... I collected ALL the files from EVERYONE (regardless of whether they were explained...) since they started working on these YT2's.... The bootloader should be the same on all the 830's. No one ever got back to say it worked (tang?????). PM me....

[Q] .141 Update linked, Thanks! (I Need a hard-bricked Atrix, read this)

====In need of donations!!!====​Also, I'm in need of a Hard-bricked Atrix. Sorry but I don't have any money to spend right now, so I'm looking for donations. This might help with the development of the ROM (Very much speed up the time it will take and testing) if I can get it to work. The most I probably can give you are credits in the ROM (literally, I will add your name to the notices that come up when you flash the zip, and on the forum page) and a copy of the pre-release version (Stable or Unstable you decide). Please PM me!!!!!!!!!!!!!!!!!!!!!!!!!!!

Solved! Thanks guys! Turns out that the set x.xxxx code had to do with the orange status bar, and Dark linked me to the 4.5.141 files... All that still remains is above...
Download the new 4.5.141 IMG's here: http://atrix.tk/4.5.141/
READ THIS BEFORE DOING ANYTHING WITH THE NEW UPDATE! You have been warned!
Come on guys, please at least help with the updater script!

Thanks but it says not to flash to a device with an unlocked bootloader. Not taking any changes. Was hoping for the boot & system .img files...
Also I figured out the set x.xxxxx thing. It's for the orange loading bar. lol.

Thanks I already downloaded them from atrix.tk
If you need a hard bricked Atrix, I got one. Its useless to me since I already bought another one, and use a Galaxy S II now anyways. I think the digitizer might be faulty as it sometimes does not feel like working unless you turn the screen off a few times, then it works perfectly.

For new users!!

This is a humble requests on behalf of all the noobies!!
I request the seniors in this forum to post a thread on how to root, install recovery and other preliminary stuff. One thread that contains all the trivial info on flashing new roms would be very convenient.
Please explain it step by step for the new users. By doing so you can encourage more and more users to download and use the custom roms.

It is critically important that you specify your exact model. "Ideos X5 U8800" applies to three or four different devices. I turned one U8800-51 into a paperweight by not appreciating the differences.

Just so you know. CWM is not foolproof. I had one device that CWM was unable to rescue from the CWM recovery boot.

Hi..

Sorry for the trouble but i am a new user here..

Rooting voids every warranty. Wether or not they catch you is your responsibility:silly:

While we are at it, new users should know that there are multiple versions of the Ideos X5 U8800. These include, but are not limited to:
U8800
U8800pro
U8800-51
There may be others. All MODs are model specific!
The exact model number is obtained through settings -> About phone. Please include the model number in all posts.

About the first sticky in the Dev forum. Please post any issues, questions, in that thread (or PM the guy above ^^^^^^^^)
Seriously, just post them in that thread, don't create a new one please.
1. Install Unlocked Bootloader and CWM
2. Install Superuser (sometimes included in bootloader app along with BB)
3. Flash Install one of the modded or OC kernels.
Life is good.
Read the stickies, and the guides, that's why we post them there.
MD

We need a proper root, unlock/relock flash guide.

I see plenty of people asking for rooting help etc. I think we need a proper guide on how to backup TA partitions on M & N. How to restore. How to flash recovery and kernels and in which order. Which tools do you need and where do you get them and when everything is set and done, how to flash a rom.
A step-by-step guide.
I see answers like "just unlock and do this and that" which isn't answering peoples questions. And the result is just people asking "and how do i do that?" and the loop of replies with no content continues. I'd be more than happy to help, but havn't had the device for long, nor have i done anything to it yet. So i'm hardly the right person to do so, yet.
Why are you speaking for these 'plenty of people'? I don't see anyone asking, it's only you because you don't put effort into looking up and reading and you want everything to be served in your plate. Everything is very well written if you TRY to search for it.

Not true! For example, you can see 3 posts in a row asking for help (including mine) and noone answers. There ARE plenty of people who need help. And noone is helping. This is a useful post.

If you read the question I posted, I said that for some people the information is not very clear and there are some things that haven't been specified. Especially for the xperia X, why are there so little threads and mods for it? Because it's new? Do you think there will be more mods and stuff in the future?

You should TRY and read the OP again, you clearly didn't get it.
And why i'm speaking for "those" people. Because no one else is. The difference is that i don't have any difficulties doing so, it doesn't bother me. You could've spend your time more productive coming up with suggestions to a possible solution, eliminating those "i need help rooting/flashing/blabla" threads. Whereas you choose the easy way and just be a prick about it.

Here you can find unofficial twrp for xperia x:
http://www.infectedbuilds.net/downloads/suzu/twrp/
Install with fastboot command:
fastboot flash recovery recovery.img
After flashing this twrp you probably cant access data partion in twrp, to fix this boot into twrp, do a factory whipe and format data partition.
If you want to root flash latest SuperSU: https://forum.xda-developers.com/apps/supersu/stable-2016-09-01supersu-v2-78-release-t3452703
If you want a modded kernel with DM-verity, RIC off, DRM fix, SuperSU & Busybox download this tool and follow instructions: https://forum.xda-developers.com/xp...oot-automatic-repack-stock-kernel-dm-t3301605

In the future I will buy this phone but now without it I am unable to do some tutorial. I wish I had this phone right now because this phone is awesome and some days ago I destroyed my M4 Aqua. I am into unlocking bootloader, backing up and restoring DRM keys, flashing recovery and making working SuperSU. I did tutorial for M4 Aqua on my Czech forum but I wish I could it here on XDA.

okay, so I can spend some time to write a noob friendly guide on saturday including information about things that troubled me too
=)) finally, I will give you a guild for step by step:
A. backup and restore:
1. fall backup to MM with flashtools (find script for your device)
2. https://forum.xda-developers.com/crossdevice-dev/sony/universal-dirtycow-based-ta-backup-t3514236
3. read inside topic to find restore code.
B. unlock:
1. go to this site https://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/ to get unlock code
2. turn on develop option (gg please) turn on oem unlock in this
3. follow sony intruction.
C Relock
relock ( use restore code in A) after that use flashtools to flash any firmware you want (like fall back MM)
ps: it is just a summary because you can fix any problem with gg in some other android devices.
ps2: dont use only one device forum to find your answer, try to find it from others. Because sony devices have same problem when flash OS )) or backup DRM and most them was answered so no one wanna write again again about same problem.

Twrp 3.4.0-0 sm-t825

Here's a functional TWRP with a revamped UI ported from the TAB S2.
I am not responsible for ANYTHING to do with this image. Use at your own risk! I can provide only limited help because I myself learned this in one week.
SEANDROID IS NOT ENFORCING? - No Problem - it doesn't mean anything! If you do know how to repack twrp in order to remove that message please show.
Thanks for the sources - @ashyx @Valera1978 and tab s2 twrp team.
I don't have a tab s3 non lte but you can try using it!
Download link:
2020 august twrp 3.4:
https://www.dropbox.com/s/fnh0wvqe8qwvqu0/t825twrp_3.4.0-0.img?dl=0 for T825!!!!
thanks to bmwdroid for sharing the file!
To flash: flash this with ashyx's twrp or Valera's repack by selecting install image and then selecting recovery!
Good luck and please press the thanks button!
Everything works!
have you tried it on your tab?
Everything worked fine. All functions are still working. I can attach a screenshot a little later
Screenshot.
Later I'll post a version with modified icons, of course, if the author of the topic does not mind
Yup I don't mind! You wouldn't by any chance know how disable the text seandroid not enforcing? It annoys me! But without doing it when compiling directly from the tarp tree because it doesn't exist; I only followed a simple twrp porting guide!
@Alex20137 thanks for this, moved tab s3 from dead point. what can be benefit of this? is it opening door to some lineage breakthrough?

@ivanox1972
I now support lineage 17 security updates, so if security was a fright from upgrading, never fear!
Unfortunately, the images that I used before are not suitable for this version of twrp. I can just lay them out, suddenly someone wants to redraw
View attachment images.zip
also installed this twrp. so far so good.
Hi @Alex20137! How did you do this?
I'll definitely try it rn on my Tab S3
Don't bother yourself - does NOT work on SM-t820 wifi - too bad.
Yesss. Don't bother yourself - does NOT work on SM-t820 wifi - too bad.
Not sure, if the installation attempt took place in the right way.
I only tried two times (install via twrp 3.2.1-1).
Maybe you have more success with a fresh system !?
Had to restore the recovery system with Odin ... I don't mind.
Still, it's nice that the two tablets are still alive and in use.
