[Q] how do i flash a custom rom

Hey guys
I wanna flash my lg swift with 2.3.2. But I don't know how to? All I know is that I need to get a rom with fastboot enabled and then I must install recovery and then I flash. But how I do all this? Is there a tutorial some where that explains me how to do it? I searched everywhere.
Phone. Lg gt540 rooted and has android 2.1 v20b
THANKS IN ADVANCED

There are plenty of threads already explaining this. You need KDZ updater. The 2.1 ROM with fastboot. After you flash these with KDZ updater you will have a fastboot enabled ROM. Make sure your battery is FULLY charged before doing any o this or your indicator will get screwed...like mine. The you use fastboot to flash the ROM via ADB. That's the basics, now go look on the forums for more detailed descriptions as they are there.

[REQUEST] Original Recovery IMG

Hi,
Was looking everywhere but could not find this, so figured I'd ask here.
I need to send my tablet back to Samsung for repair, but need to remove CWM and put the original recovery back...
Can anyone post the original recovery IMG?
If you followed the instructions from here you should have file PART8.IMG... that is what I need.
Thank you!

[Q] HELP! Lgl22 root, model information check fail!!

Hi everyone! I'm new on xda, I really need help please.
I'm using an LG l22 isai, I have updated to android 4.4.2 v20b, now I am trying to root the device but I have an error. LG flash tools says "Model information check fail". Does anyone knows how to fix it? is there any dll file that bypass the verification and goes straight to the flashing? please help.

try these things, this is just an quote of what I have found,
USB cable is not broken? Are you connected?
· Do you have installed the driver?
· DLL or thing that is compatible with the tot you are using?
· Flash Tool Are you running with administrator privileges? (You can run as an administrator by right-clicking)
Do you put in · Download Mode? You may have already confirmed, but please try to check the above points.
Somebody with the same problem as you said that he fixed it with replacing his usb cable.

I double checked all of that, I re-downloaded all the files to make sure that the files are not broken or something, I run everything as admin but still no result, same problem .. it says "model information check fail".

Hmm even with another cable it fails but you can still boot normally into the android os right? Sorry if I am also giving some reactions a bit later but your problem only have a couple people with lots of time no reply or good answer. I am now busy with studying for 3 tests next week so when I am done then I will search more for you alright?

yes I can boot into the os but can't root it. good luck for all your tests, I hope you can find any solution later. I'll search more on google if I can find any solution.

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.

you choose the easy way

I don't understand what's so wrong with helping some people out..

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

Thanks a lot!

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.

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

Upgrade A501

Hello all,
Im posting here because no one seems to be able to answer me in the Android General section, I hope to get better chances here
I would like to upgrade my IconiaTab A501 because most of applications are not compatible with my version (as it says).
It is Android 4.0.3 and I would like to upgrade to the lastest one.
I have tried to do the system update but it always says "the network cover is too low please move to another place" to get better cover. I have read on internet that this message means it cant be upgraded by itself thus we need to find another way as it does not concern wifi but just Acer stopped to develop firmware for Iconia tab A501.
I saw that its now Android 9.1 but i am not sure it can be installed in my tablet and too much customs firmwares exist but I really don't know which one is the most stable and can run all apps.
Could you guys please help me to know which is the lastest Android version i can install in my A501? Or one that can make me run all apps normally?
Also my image is Acer_AV041_A501_RV20RC08_WW_GEN1
Thanks for your help

Your going to have to root and unlock the bootloader, the newest version of Android for this tablet is 5.1.1

Thank you
Thank you very much for your help!
Thats the only thing i wanted to know thanks again

Thank you very much and sorry for the late reply i was on holidays
I saw Lolipop 5.1.1 was not really stable so I try installing ICS 7.2.0 that u gave which look very stable as i saw on forums.
To get my CPUID, I have followed the steps below:
open yr file explorer, esfile explorer is a great one....
navigate to:
/sys/firmware/fuse/acer_cpuid - add a zero to the front!!! easy peasy
I sent u my CPUID on pm (I do not know if its confidential or not, as maybe its a thing that shoudnt be posted on forum)
Does it looks like a CPUID to you? (I am wondering because on the video below it shows something different)
I thought about using this tuto:
https://www.youtube.com/watch?v=cVLCNXf_QoI
But its not exactly same files he is using as the one you sent me. Do you know, by any chance, where i can find the install tuto with the blackthunder's files you sent me?

Yes that does look like your cpuid but you need to convert it to an sbk. https://forum.xda-developers.com/showthread.php?t=1810618

Hi Turnert,
Thanks for your reply. Is the SBCalc.exe safe? It has been quarantined by my antivirus looks like it contains: W32\Exploit.gen
Do you know anything else that can convert my cpuid into SBK? (I'll search deeper on my side the time you reply just in case )
Also is the video tuto above good to root with the files i Have or you know a written tuto that matches my request?
Thanks again for your help and have a good day

Ok I got my SBK using this website: http://acerhacks.com/sbkcalc/
I will wait to know your answer about the tuto above if i can use it or if you know a good one with same file I have or a one that describes step by step everything
Again and i think you know it, thanks !
