Hello everyone,
I have a Samsung Galaxy S2 i9100 and I'm trying to install Lineage OS 7.1. The flashing goes smoothly but when it reboots, I type the SIM's pin and I get the "SIM operation failed" message. I remember I messed around with the efs folder some years ago but after that I have been able to flash several ROMs, CM 12.1 for instance. I tried to flash CM 13 but I did ran into the same problem, I couldn't go beyond the SIM's pin screen.
I'm trying to use EFS Professional but in the Device Filters menu there's no Galaxy SII and no matter what device I choose, the Device Partition window stays blank. I can not do anything with it.
The current IMEI in my phone right now is 004999xxxxxxxxx. How can I reset it to the right one? I'm desperate!
Try reinstalling 4.1.2 With Odin and reflash LineageOS​ :laugh:
Following is worked for me on my Samsung Galaxy S3 i9300 with LineageOS 14.1:
1. Flash original ROM with Odin. (if at this moment IMEI is not correct use program "Samsung Tool" to manually edit IMEI)
2. In security setting, set SIM card lock to none. (After this you should permanently disable SIM pin request on startup on every new ROM)
3. Flash custom TWRP recovery with Odin.
4. Root phone.
5. Make nandroid backup of EFS using TWRP.
6. Wipe cache, system, boot, data and flash custom ROM (do not reboot system after flash).
7. After flashing custom ROM, restore EFS using TWRP.
8. Flash Opengapps, wipe cache, dalvik cache and reboot system.
9. Set everything up Google account...etc.
10. In options check if IMEI is valid. (If is not, reboot to recovery and try again to restore EFS)
If you don't have working cellular network after flashing custom ROM, read following:
From Play Store install app "Cell Network Reset".
Open app and run "Reset Cell Network". (This step is weird because some times after few minutes i get working network, some times after few seconds. Also some times i need to run "Reset Cell Network" few times in a row to get the network working)
I hope it will work for you
Good morning to you all, and thanks in advance if you can help me.
I just received an Ace 4 Neo from a neighbor who asked me to 'make it faster' and 'newer'. Naturally, with the Stock ROM what Samsung overloads, I wasn't going to do nothing as close. I came to the always loyal xda and found the Mega Thread of Ace 4 Neo: https://forum.xda-developers.com/ace-4/development/rom-cyanogenmod-11-12-13-ace-4-neo-ace-t3627637
I put into the phone the oldest Stock ROM available from the same origin country and carrier (TIGO - Paraguay), and after installed Custom Recovery TWRP 3.1.1-0 and tried to install a Custom ROM. There is where my problems started.
First, I tried to put CM13 or MIUI (Android 6.x) with no success. The phone when turning on just showed the model and stayed there. The only change was a red exclamation sign on the upper part of the screen. (Possibly, this will be helpful for you: When installing, the result said [ ] instead of [/system])
After 6 failures with each one, I desisted and instead tried with CM12.1 and this one successfully installed. I also tried to use OpenGApps Pico (as I really messed up trying to find how to install the GApps of the thread), and the phone turned on "without problems" (the CM in fact started, but the red exclamation point is still there).
After 8 minutes configuring the GApps, I configured the Google Account and such. However, I went to Play Store for naturally install WhatsApp, Facebook, Twitter... The common things.
Surprise! The phone when installing suddenly rebooted. When turned on again, the home screen closed and opened 4-5 times in 20 seconds and rebooted again. It maintained on that loop over and over.
So, am I doing something wrong? Or do you know about how to fix any of the previous issues?
As a final note, because the Mega Thread doesn't have the classic installing instructions, after navigation for 2 hours I constructed this steps:
1. Reboot to Custom Recovery
2. Wipe > Advanced Wipe > Everything except Internal Memory and SD Card (Dalvik + System + other two things)
3. Install ROM
4. Wipe Cache/Dalvik Cache (the button what shows there)
4. Install GApps
5. Wipe again Cache
6. Reboot
Again, thanks in advance.
Hi, @Pedreo1997. You need wipe internal storage, too.
Step-by-step install custom ROMs:
Flash oldest stock ROM with Odin.
Reboot system > use 1-2 minutes ( for sure )
Install TWRP 3.x.x
Wipe everything except sdcard.
Wipe > advance wipe > check system > option > repair
Install ROM and Gapps.
Reboot and enjoy
My device is redmi note 4x (mido), I've tried lots of different custom roms, i'm installing these roms as the instructions say, but I always get some problems like camera crashing, default file browser crashing, corrupted package installer where you cannot install any app where it just says app not installed. Now I'm stuck without sim card and wifi working I currently have OrangeFox-R8.3-mido twrp
I tried roms like resurrection remix, lineageos, havoc os and all of them have some issues and other users don't experience these for some reason.
I tried to wipe literally everything possible in the twrp (maybe wiped too much?) with different combinations, format data, factory reset and also advanced wipe> and tick everything form here, then I install the firmware if the rom instruction says so > flash rom without wiping cache, flash newest open gapps arm64 usually 9.0; nano and then hit the reboot and usually bit laggy(and sometimes crashy) google setup pop ups, and if it doesn't fail on the setup I get some of the problems I talked before. Anyone also had problems like these?:crying::crying:
The only wrong thing that I see in twrp is
Code:
mount: failed to mount /dev/block/bootdevice/by-name/sec at /firmware: Invalid argument
it's written with white text(not red as usual errors)
I prefer u to wipe everything. And switch to orangefox r9 and wipe everything and then install any trble rom. See if thus works

I updated the orangefox and it didn't help, tried to download the normal twrp from https://dl.twrp.me/mido/ and it still doesn't work,
It doesn't see my sim card, wifi during settings and I can't even turn on the bluetooth
Here's a quick guide to some of the basics.
Which recovery.

Use the latest from here.

Do not use Orange Fox unless you intend to stick with stock MIUI. Orange Fox has extra features, which are almost all aimed at MIUI, but it often causes issues flashing custom ROMs, so it's a long way from the best option if you want to use custom ROMs. Orange Fox, along with other TWRP derivatives, allow complete access to virtually all of the phone, so it is very easy to accidentally hard brick the phone if you don't fully understand what your doing.
Ignore anyone who tells you to use Orange Fox when using custom ROMs.
Do I need to permanently disable encryption
-------------------------------------------------------------------------
No.
There is not a single reason to permanently remove encryption, other than personal preference.
It is recommended to have encryption removed when flashing, but this is easily done by temporarily removing lock screen security before flashing and adding it back after.
Ignore anyone who tells you that you need to flash a DFE (disable force encrypt) script.
Should I wipe all my partitions when flashing
------------------------------------------------------------------------------
No.
When clean flashing you only need to do a factory reset in TWRP.
There is absolutely no need to wipe system or vendor partitions. Ordinarily, when flashing, there is no need to go into the advanced wipe menu. I've had this phone 15 months and have never used the advanced wipe menu and have never had any issues.
When you flash a custom ROM, it will automatically wipe system first, so you don't need to do this yourself.
When you flash a vendor file, it will automatically wipe vendor first, so you don't need to do this yourself.
Even though almost all (it may actually be all) ROM flashing instruction tell you to wipe system, it is not needed.
Ignore anyone who tells you to wipe anything more than data, cache and dalvik.
Do I need to update my vendor and firmware when flashing a new ROM
-----------------------------------------------------------------------------------------------
Probably not.
If you currently have MIUI installed and it's up to date, then you will have the latest firmware and vendor and won't need to flash them.
If you're moving from one custom ROM to another, then it depends on how up to date your current ROM is. If the vendor and firmware requirements of the new ROM match the requirements of your current ROM, then will have the current vendor and firmware already installed and so do not need to flash them again.
Only when the new ROM needs a later version of vendor and firmware than you have currently installed will you need to flash them. This isn't such a common occurrence, so you'll not need to flash vendor and firmware often.
How to install a custom ROM over MIUI and remain encrypted
-------------------------------------------------------------------------------------------------
Assuming you have already unlocked the bootloader.
1 Boot into fastboot
2 Flash TWRP (fastboot flash recovery <path to TWRP file>
3 Immediately boot to TWRP (fastboot oem reboot-recovery)
4 Select Wipe Menu and Factory Reset
5 Return to Wipe Menu and Format Data
6 Return to Main Menu, then select Boot Menu
7 Select Boot to Recovery (this reboots TWRP to ensure the data partition is properly mounted after formatting)
8 Copy ROM and extras over to phone and flash them.
9 Reboot and enjoy.
Do not add any extra steps, do not miss any steps out
How to dirty flash a custom ROM update when encrypted
---------------------------------------------------------------------------------------------
1 Remove lockscreen security (this removes encryption)
2 Boot to TWRP
3 Flash the ROM update (plus vendor and firmware if the requirements for these have changed in the updated ROM)
4 Select to wipe cache and dalvik when the update finishes.
5 Reboot the ROM
6 Restore lockscreen security
How to clean flash a new custom ROM over another custom ROM
--------------------------------------------------------------------------------------------------------
1 Remove lockscreen security
2 Boot to TWRP
3 Select Wipe Menu and Factory Reset
4 Flash the ROM plus the extras you want (this includes new vendor and firmware if the requirements are different to your current ROM)
5 Reboot the ROM
6 Add lockscreen security
Thank you
Thank you very much for this. I just bought the device last week . Since i am upgrading from a lenovo vibe k5 plus (which also had a decent amountt of development support) i have a few questions. With the vibe k5 plus, installing a custom rom was very simple. flash cutsom recovery-factory reset (i used to wipe the internal storage too)-flash custom rom-flash magisk and you're done. My question(s) are 1) What is this "Force encryption" that we have to disable/keep enabled. 2) what are vendors and firmwares. I'm currently on MIUI10 (Got a Nov 2019 unit), it's pretty decent for now.

Since, I think, Android Marshmallow, Google have added forced encryption. Before this you had the security menu option to encrypt your phone storage, which required a separate password to be entered on every reboot. Now encryption is done as standard and uses your lockscreen security PIN/password as the key.
Initially your phone will be unencrypted, but as soon as you first set-up lockscreen security the phone will be automatically encrypted.
Many people see this as a good thing. Should you lose the phone, you data is secure and cannot be accessed without the lockscreen PIN/password. Other people don't care about this and so prefer to disable encryption, as it makes life a little easier when flashing custom ROMs.
Some people, incorrectly, believe that disabling encryption is necessary when flashing custom ROMs, or that disabling encryption is the only solution to problems seen when flashing. This is not true and disabling encryption should only be about a users personal choice to be unencrypted.
Think of vendor and firmware as the equivalent to device drivers for PC components. They are a collection of compiled code files, provided by component manufacturers and the phone manufacturer, to allow Android to communicate with the hardware components in a standard way. Occasionally these files might get updated, as part of a MIUI update, to fix a bug or to add extra functionality. When these files are updated, custom ROM devs will include them so that they get the bug fixes or extra functionality. When this happens they will update the minimum vendor and firmware version requirements for their custom ROM - the version will be the actual MIUI version in which the vendor and firmware files were updated.
Thanks that was a really good explanation. I have one last question, so right now I'm on MIUI10 I've got the MIUI12 update notification but I want to try MIUI11 first. I've got the ROM file from the xiaomifirmwareupdater website, how do I flash it?

Are decrypted devices faster? Also please suggest stable roms. Also has anyone used 81hz extensively? Does it damage screen? Does it drain more battery?

As far as I'm aware, there shouldn't be any noticeable difference in speed. The whole data partition is encrypted as a block, so, in use, accessing files is done on an already unencrypted partition. The individual files are not encrypted/decrypted on demand on an individual basis.
All of the popular ROMs will be stable enough for daily use. Which one to go for depends on what you prefer - more AOSP, more Pixel Phone, more heavily customisable, etc., etc.
I've never gone for the screen refresh rate mods, so can't comment on them.
Thanks for replying.

Which custom rom do you use? Does it have any bugs (Like under screen fingerprint not working)?

I'm currently using LOS. It's mostly bug free. There seems to be a current issue with wired headphones - on calls it is using the phone mic instead of the headphone mic. For my use, I don't see any other issues, but there could be other things around functionality I don't use.
Fingerprint recognition is about as good as it gets on custom ROMs. Not quite as good as MIUI, but good enough.
Thank you so much for busting so many myths, I was dying for someone to speak up but couldn't muster the courage myself. Hats off, and I support everything you said 100%.

The first boot will take a bit longer, but only a minute or 2 at most. Something has gone wrong. Make sure you follow the guide exactly.
The most common issue is not formatting the data partition. This is not the same as wiping the partition. When formatting TWRP will ask you to type 'yes' to continue. When flashing over MIUI this is necessary to fully remove encryption before flashing.
Another common problem is wiping partitions unnecessarily. There is no need to wipe anything. Just do the factory reset, this wipes what's needed and nothing more, then format data.

I did the TWRP format (which prompted me to type yes to continue) and wipe data partition,but didnt wipe the partition itself, rebooted, installed pixel experience, and still same, i even got into a boot loop, which i got out to, by forcing my way out by fastboot, and reinstalled MIUI,
Im currently at MIUI, currently stable.
So Im going to try again some other time about this, when i have another available device to use while i reinstall pixel experience in Mi9T Pro
But, your guide is helpful, it failed on me probably because of a mistake I made.
Thanks anyways!
Best Regards.
hi,
in your guide, you do not have added a step for flashing the vendor.
is this intended ?

Flashing over MIUI, I've made the assumption that you'll be on the latest version of MIUI and the original region, which should therefore already have an appropriate vendor and firmware for the new ROM.
If you've not kept MIUI up to date or have flashed a different region of MIUI, then you may need to flash the correct vendor and firmware file(s)

thanks for that. i followed as you said and i was able to flash Evolution X
however, while flashing i got a warning in TWRP E:Unable to decrypt FBE device. The ROM booted fine but I think I have made a mistake. Additionally the folder I had created to transfer the ROM is gone after the phone booted.
What could be the issue ? and how to resolve this ?
FYI, I'm using Mauroonofrio's TWRP

I've had that error a few times. It's normally from when your first boot into TWRP. All output from TWRP gets written to the same output screen, so when it is shown you are not seeing output from just the last command but for the whole session. If you had looked in more detail, you would have probably realised that the error was from before you started flashing.
With the ROM files going missing, that is a known problem. Actually anything copied before flashing gets lost. The first time it happened to me I had copied all my backed up data at the same time as the ROMs and it all got wiped. I can't remember exactly the details now, it's just something I've got used to. But if I remember correctly, the data disappears when you first boot into the new ROM. After it happened the first time, I checked in TWRP the next time, after flashing, but before booting the new ROM and the files were still there. It was only after booting to the ROM that they disappeared. (My memory is a bit vague now as it was over a year ago, but I think it might actually happen when you set up lockscreen security and the phone is encrypted in the new ROM for the first time). Maybe someone else can confirm or give the correct explanation.

Yes, both things are normal. You should be good to go with your new ROM. No need to reinstall it.
