[Completed] [Q] What is a recovery.img and what is it for?

Hey guys,
I was looking for a tutorial and a description about what is a recovery.img and if there is always the need to root any Android or Smartphone (even if it comes with Ubuntu mobile OS) to install a custom ROM.
My second question is about the Super User Apps:
I always see tutorials in which, after flashing the recovery.img they say we need to install a, i.e., CWM_SuperSU_xxx.zip. I do not know why to do that if I have my phone rooted and all I need to do is to boot it and go to the Play Store and install the latest SuperSU app by ChainFire, i.e.
All these questions have a single porpuse: To know what I am doing, because I do not like to perform tasks as an robot. I have a brain that loves to know and learn and be aware of what its doing.
Thank you very much for your help. Maybe you could point me to the documents I need to read to now all these questions.
By the way:
I rooted a year ago my HTC One-V and installed a Custom ROM before and It was working perfect until somebody stolen it from me.
My device now is a Samsung Galaxy GT-i9300. I am from PerĂș, and my Service Provider is Claro.
I use Ubuntu 14.04 and 12.04 and I have installed Heindall from the Ubuntu repositories. Until now I just read tutorials of how to root my phone, but I do not want to perform tasks without knowing what are them for.
So I want to wait before rooting my GT-i9300 until I know what I am really doing with my phone.
Thank you in advance!
Regarding Rooting, Please see [Q] What is rooting? Particularly #7
When it comes to Recovery, See XDA Wiki. Also See XDA University for Android Flashing Guide.
If your Device comes with Linux, then you should not use Android Rooting programs unless advised to do so. Weather Device Recovery works with Linux or not depends on Case by case basis.
In case of additional questions, please post in Android General
My device is a very popular one, a GS3 GT-i9300. It is an Android phone.
My PC, where I am going to connect my phone to root it that has Ubuntu Linux 14.04 and 12.04 installed.
Maybe you miss understood what I wrote.

So if I want to use CWM Recovery, then I can look for the latest version? Or there is a special version for my phone. Afaik it is exactly like my PC when I install a dual boot with Windows. The bootloader (maybe Grub2) is like the Samnsung bootloader and Recovery and my Android are like Ubuntu and Windows dual booting. Is that right?
And hence I do not need a special CWM Recovery for my phone, it should be a simple recovery.img installer but versions differs in features and installed programs. Is that correct? And I just can look for the latest one.
Mauricio Mora
Thank you very much @Perseus71
Your links are very useful for my purpose.
Mauricio Mora
So...
In simple words, it is like my PC.
I inicially have a single OS, Android. Maybe a Recovery but installed by the manufacturer.
Then if I install a Custom Recovery, it is like creating a dual boot: Android and Recovery.
Then if I install a ROM it is like removing a Linux distribution in my PC and installing a new one.
Recovery gives me some tools like backup my personal settings and data and even my apps.
In those terms, there should be ways to install dual boot Android and Ubuntu Touch? Or which ever ROMs in dual boot?
Mauricio Mora
If you want to install CWM, please visit [RECOVERY] ClockworkMod Touch 6.0.3.2 for GT-I9300
Mind you that is for GSM Phone only.
Yes Bootloader = Grub but Linux/ubuntu do not have a concept of Recovery in traditional android sense. In that wany Grub does do the job of a recovery. You may want to google for "What is Android Recovery ?"
If you still have continued questions, please post them in Galaxy S III General forum.

Lenovo s5 (k520) ZUI 3.7.177 ST Got root anyone?

Just got a new Lenovo s5 (k520 running ZUI 3.7.177 ST) but can't root it (tried KingRoot and Root Genius so far).
It has a nasty little OS (ZUI 3.7) which keeps killing apps it doesn't like. It took me two days to find an adblocker which would work (AdClear) after trying Dns66, Blokada and a couple of others which I can't recall. It's tightly locked down.
* Anyway, my question is... Has anyone had any luck with rooting this phone or OS?
* Or, has anyone any suggestions for apps or rooting options which might be more successful?
If there's any other people out there with this phone, I would seriously consider chipping in to buy one for a dev to work with... give me a yell if you're interested.
Cheers,
Specs:
OS ZUI 3.7 (based on Android O)
CPU Qualcomm Snapdragon 625 2.0GHz Octa core
ROM 64GB
RAM 4GB
Edit: Hmmm, I was hoping that the latest Magisk beta (16.6) might help, but no luck. It does seem to get further along but fails with an 'unable to find boot image' message (my apologies for not being able to quote that accurately). Nothing seems able to find that .img. Can't back it up either as no app can find it. Yes, I need to brush up my adb skills ...my last effort ended in an error reporting lack of appropriate key, as I recall (sorry, have a bit of a flu just now). Anyway, has anyone else been able to look at this phone? Anyone have any ideas (or just thoughts) about what I can do here?
Thanks.
Just to update.... I have tried every simple rooting option I can find -with no luck.
I have found one reference to installing twrp & rooting this phone, but I'm unsure how legit it is ...it just looks a little like its put together by a script; but maybe they just copy/paste a lot when writing tutes? (I have written to them but have had no response from them in a week). The tutorial makes reference to a dev/group in China successfully installing twrp, but only on a Chinese release, not international.
Anyway, I'm wondering if anyone knows of the group or people referenced at
http://tutoraplikasi.com/cara-root-lenovo-s5/
or if anyone might have an idea of the dev(s) in China working on twrp & lenovo?
Just a shot in the dark, really, but I thought I'd ask anyway.
Cheers.
OK, looks like time for some more serious reading and brushing up of old, much neglected skilz... I will probably close this thread and open another ( if there's no objections) in the xda twrp forum.
If anyone is interested, I'm looking to compile twrp for this device with a view to flashing magisk. Hopefully, it will work. Seems that adb & unlocking the bootloader is the only way I'm going to get to actually see the partitions holding the IMG files etc. (Though I do have one or two ideas about escalating privileges/permissions, but that's a whole other bunch of research -and time which is always short.)
Anyway, if you have an interest in rooting this phone have a look for a thread under twrp Q&A.
Cheers.
Seems like it was just a matter of waiting... XN Logos has come up with a solution, it appears --
https://www.stupdroid.com/2018/07/root-twrp-lenovo-k520.html?m=1
At least I managed some in depth reading in the meantime. I'll report back on success of the procedure.
Hi I have also a Lenovo s5. I hated zui 3.7 too and I succeded in installing Lineage OS 15.1 by phh using only fastboot mode... I tried rooting It but unsuccessfully. Now I want twrp and if it would be possible even root. Did you succeed with XN Logos?

Haven't actually tried yet. After all that looking for a root solution I now have been too busy. Will probably do it this Wednesday. I'll keep you posted. Did lineage work well? Any bugs or other issues? ZUI is a dog.
Yeah everything is okay... In the previous updates there was a problem with the audio in ear but now is solved. The only thing that is a little (but not dramatically) worse is battery life because in zui the fact that the os kills every app in background makes the battery last longer.
Hey guys, I know it is no the perfect thread for this yet this phone almost doesn't exist anywhere on the internet. I have the same issue with apps closing as you do. I wanted to install Lineage OS yet as there is no official release for lenovo S5. I would really appreciate some guidance on which release would I install and how. Would it be via the twrp? Thanks in advance.

Hello, I'm a lucky owner of this beautifull beast, the Lenovo S5 K520, but with the horfull ZUI3.7. I always have been using Cyanogen and after lineage OS.
It did not luck for me to install it on the Lenovo S5.
I manage to install TWRP-3.2.2-0713 with the help of the S-Droid toolkit for Lenovo S5.
From there, I did try every rom from phh on this page : https://forum.xda-developers.com/project-treble/trebleenabled-device-development/lineage-phh-treble-t3767690
but the best I did get is the first logo of lineage OS going on and never stop for hours. I also did try AOSP treble Rom from this site : https://forum.xda-developers.com/project-treble/trebleenabled-device-development/experimental-phh-treble-t3709659, but there I'm getting the Android text changing of ligth theme, but bothing more.
Could you please tell us the procedure and the version of the software you are using so that you are able to use Lineage OS on a Lenovo S5 K520?
Thanks a lot.

Hi i did in this way...
1)fastboot -w
2)fastboot erase modemst1
3)fastboot erase modemst2
4) fastboot erase system
5) fastboot erase boot
6) fastboot erase recovery
7) fastboot flash recovery recovery.img
8) fastboot flash boot boot.img
9) fastboot flash system {systemname}.img
The only thing you should do firstly is download the firmware from a video in YouTube whose name is like "ROM Lenovo s5" or something like that and extract the firmware in order to have both boot.img and recovery.img. Hope I could help
P.s. I used phh lineage latest build
Lenovo S5 global version stock rom
Hi everybody!
I was wondering if any of you have a copy of the original ZUI 3.7 non-Chinese stock firmware. I had trouble with my phone and contacted the customer service. Unfortunately, they've sent me the Chinese version (K520_CN_OPEN_USER_Q00011.0_O_ZUI_3.7.355_ST_180412_qpst) and now my phone is almost unusable as the rom only contains crappy Chinese stuff... :crying:
All apps are Chinese and it contains no GApps... I cannot even restore previously save config.
Please help me and send me a backup or the original non-Chinese firmware.
Thank you very much
I didn't even know the existence of an original firmware for non Chinese phones indeed when I bought it it came with a horrible chinese firmware with few translations. Did you find it? Because I want to try it too. If you didn't find it I'm also going to look for it

I need to edit build.prop file on my J3 without root. Is it possible?

Hello team. I need to edit build.prop file on my J3 but I cannot root.
My understanding is that this is possible using custom recovery, just mount the system partition and push and pull the file file with adb. The problem is my handset (SM-J330FN) is running Android 8, and I think only custom recovery exists for Android 7. I tried installing the TWRP I found for Android 7, but the phone just boot loops, get stuck at Samsung logo and reboot. Don't think I can use this Android 7 TWRP with Android 8.
So next plan, I tried to wipe and install Android 7 firmware instead, but Odin said no. I take UK BTU firmware from updato.com the same way I do with Android 8 but it gets to the first stage and Odin says FAIL!
Can anyone provide a suggestion for how I can edit build.prop without root? I don't care how - maybe I can find a custom recovery for Android 8, maybe someone can help with why I can't install the Android 7 firmware, maybe someone knows of a way I can do a 1 time boot to recovery image (have used "fastboot reboot recovery.img" in the past but am aware that Samsung bootloader does not support fastboot). Maybe I can do it with root and remove the root after? Root needs to be not detected so I can use certain tools.
Any advice hugely appreciated

You obviously ignored my reply I gave you yesterday.
As I already stated TWRP fully supports your device on Oreo.
Your issue is not reading the thread properly.
All you need to do is explained in the TWRP OP.

Hello, if you look at the times you will see that i made this post before I commented on yours!
I did not ignore your message, I just had not seen it yet.
As it turns out, you were right - I just tried again, taking extra care to follow instructions exactly and this time it works.
Leaves me with mixed feelings, because I am really grateful for the great development work you have done to help people like me, but also the way you are speaking to me above was a bit rude and I do not deserve that just for a small mistake. I was polite.
Thank you regardless.

There's a difference between being rude and being direct.
I am the latter.
Nothing personal was included in my reply nor was it intended to be.
You're upset, but I also get upset when people cannot seem to take the time to read the descriptive instructions I've included in my posts.
Trust me, it takes far longer for me to create this stuff than for yourself or anyone else to read and apply the instructions.
Don't be offended it's just frustration from my end manifesting itself in my posts.

Qualcomm Crashdump

Hi all
I have just bought a new Oneplus 6 and wanted to install Lineage Os.
I had initially set up the OP6 with my google account and installed some minimum apps over a couple of days. The phone updated a couple of times. I think I started on Android 8, it definitely updated to Android 9 and I think it updated to Android 10. But I am not completely sure of this because I did not take notice at that stage because I didn't realise that this might have significance..
I followed the guide from the lineaoge os wiki here
wiki.lineageos.org/devices/enchilada[
I got as far as using adb to Fastboot boot twrp-3.3.1-2-enchilada.img (which was the latest image in the dl.twrp.me/enchilada/
It then got stuck in the qualcomm crashdump line on screen.
I spent a day checking posts, including here on XDA. There are a lot of posts dealing with this issue and I did try to follow some of them with less or more success but no resolve. I downloaded Android 9.02 and used the following instructions
techtrickz.com/how-to/recover-oneplus-6-and-6t-from-qualcomm-crashdump-mode/
The routine started to run and then posted a series of error messages and exited. ( I have a screenshot of the terminal window but cannot see a way to post it here)
I have tried to research this further and there are plenty of posts and lots of suggestions. But to be honest I have become confused as some of the posts give significantly different solutions to each other.
I wondered whether it would be possible to give me some help or point me in the right direction to a post which is current and has the steps that I am likely to need succeed..
Thanks in advance for any help you can give.

I would recommend using fastboot flashable stock rom from here. People also like to use msmtool, but I feel like it is an overkill.
Please note this warning:
These ROMs can't be used to update or downgrade your phone but just to restore your phone, so don't use them to come back to oreo or to update from oreo to pie.
So grab the latest oxygen os 10, and follow the instructions to flash it. After that, if you are feeling a bit paranoid maybe download a zip from oneplus and do a local update. You now should have your phone back.
Official TWRP does not support android 10 yet, as far as I understand, so that is probably the issue. If you want lineageos 16, you should downgrade to android 9 using a downgrade package provided by oneplus and then update to Oxygen OS 9.0.9.
There is unofficial twrp by mauronofrio that supports android 10. If you want to go from OOS 10 to some other android 10 rom

Thanks very much for your helpful reply. I am now back to a working phone with Oxygen os10. And you have also explained what was wrong when I tried to fix it, I was trying to load an Oxygen Os 9 on a phone that had already been upgraded to 10 and you have explained what went wrong in the first place, I was trying to flash an incompatible TWRP image onto Android 10. So your short post has explained a lot. Thank you.
I am not feeling paranoid unless you advise that I should be and I do want to install lineage os. So I need to revert to Oxygen Os9. I have looked on the Oneplus site and that have found the option to Upgrade to 10.3 but no option to downgrade. In the Oneplus community there is a link to downloadable ROMs, these are divided into a number of folders some of which look not applicable. There are three folders that look of interest
1. Signed flashable zips
2. OTA incremental update zips
3. Stock boot-recovery images
Here is the link /forums.oneplus.com/threads/oneplus-6-rom-ota-oxygen-os-mirrors-for-official-oxygen-os-roms-and-ota-updates.835607/
I can see it is not the OTA Incremental that I need but am unsure if it is signed flashable zips or Stock boot recovery images. or whether it is neither.
Do I flash as normal or would it be a local update?
I would be grateful for any further advice.
Thanks again and for any help provided now.

I have had luck with this downgrade package. I basically googled it, the package is hosted on a legitimate website, so that's what I used. Just download it, put it on your phone and do a local upgrade through updater app.
Once you have done that I would recommend upgrading to the latest Android 9, which is OOS version 9.0.9 I believe. Then go ahead and follow instructions to install lineageos.
I am actually on LineageOS 16 + MicroG right now, so I ran into the same problems you did Glad I could help!

Thanks so much for your reply again.
I used your downgrade link and that all worked well and then let it upgrade to OOS 9.0.9. Again all very positive.
I then tried to flash TWRP to the device using this image "twrp-3.3.1-2-enchilada.img" It appeared to flash okay. Then I issued the command
"fastboot boot twrp-3.3.1-2-enchilada.img" over my adb connection and it returned to the Qualcomm Crashdump error.
I presume I have to start again with the exception that this time I can use a flashable stock rom that is OOS 9.09? Is that correct?
Then do you have any suggestions for getting round the TWRP problem? Did you use a different version?
Thanks in advance for any help.

"fastboot boot twrp-3.3.1-2-enchilada.img" over my adb connection and it returned to the Qualcomm Crashdump error.
I presume I have to start again with the exception that this time I can use a flashable stock rom that is OOS 9.09? Is that correct?
Then do you have any suggestions for getting round the TWRP problem? Did you use a different version?
Thanks in advance for any help.

Hm. Yes, unfortunately the safest thing to do is to start again. But you can start with 9.0.9 right away.
People have been discussing a similar issue here. It seems like using unofficial twrp by blu_spark helps. Maybe twrp-3.2.3-x_blu_spark_v9.91_op6.img or maybe try the latest one.
Also, make sure you read the instructions on lineageos website. Make sure you have oem unlocked, usb debugging enabled and you clicked "always give access to this" device or something, do the fastboot set_active a. I have also used fastboot flash boot_a <recovery_filename>.img. However, I do recall using fastboot boot <recovery_filename>.img some other time and I think it worked....
Anyway, yeah, maybe try this modified recovery by blu spark and follow the instructions carefully.

Thanks very much for your helpful reply and apologies for the delay in my reply to this post, I have been tied up with work the last couple of days.
I did re-install OOS 9 and then followed the instructions on the Team Win site to install TWRP in the Oneplus6. I had success after I used the latest TWRP image and zip from that site . I was then able to install Lineage OS and Microg as I wished.
So thanks for the help all. Really appreciated.

Great! I am glad you managed to fix your phone! Enjoy

Is there a SUPER NOOB thread anywhere to help me with my 7 Pro??

Hello Everyone.
Been rooting since my first HTC Hero- never thought of myself as a noob until this One Plus 7 Pro! Its the US/Global unlocked model. This thing is KILLING ME!
I've followed about 5 different "rooting for beginners" threads from different sites and I still cannot get a basic, working root. I have unlocked bootloader with no issue.
I've had fastboot bootloops, lineage OS bootloops, stock Rom bootloops, stock rom booting up but wifi did not work. I've tried everything on Oxygen 9 and 10 (using the respective TWRP). I've used official and unofficial TWRPs, different versions of Magisk.
I've used the msm tool to reset this thing about 7 times! So as you can see, I'm at a loss.
The only thing I can think of is that I'm screwing something up as it relates to TWRP and Magisk and my flashing/booting process with the A/B slot stuff. Read threads on the benefits of A/B phones...but since I'm having so much trouble, I hate it!
Overall my goal is to get a stock rom rooted; but I couldn't resolve the no wifi toggle issue. I read on one thread that I just needed to flash a custom kernel. If that is the only actual fix, then I should be good to go, but I'm skeptical and figured I messed something up.
So like my title says - Is there any thread out there that someone can refer me to?
Thanks in advance.

What version of the is are you on right now
I just reset with the msm tool, so it's back to OOS 9.5.3GM21AA.
It will take OTA updates fine up until before the 11 beta
My model is GM1917 (12GB RAM + 256GB ROM)

I did that exact one a couple of times and when I get it back booted into stock the Wi-Fi does not work. The toggle stays in the off position.

Thanks Gr8man001.
Thought I had done this guide before and done it correctly but I buckled down and tried it once more (slow as molasses) and was able to get twrp and root! Appreciate it.
