brief assessment of the costum rom "pemergency" mod = which must be paid
- Setup / flash -> OK
- IMEI must be corrected manually by terminal as tool does not work
- Constant error message "simcard failed" (slot2) although only 1 slot has
- "apex launcher" can not uninstall, then stops at the boot process lenovo screen -> I would also like to use but "default / original" surface.
- Spoke only Russian / English / chinese integrated as standart
- Morelocale2 indeed is an alternative but not "original"
ok, first feedback - hope the rom is modified?

a) no comment
b) IMEI must be corrected and it is mentioned in a manual, it doesnt need to be done by terminal, you can simple generate a file and swap with a root explorer
c) This Rom is for A2107a-h which is a 2 slots device, so I dont see a problem on this point
d) I said as this is modiffication, I decide to remove a stock launcher, you can install any other one of your choice
e) I also answered to your question as for german language only original apps are translated and the main system, on other threeead is clearlly said as this rom using more locale 2 for translation.
f) and as a last one, why you expecting anything original in a modiffied ROM?
I stoping to doing anything with this ROM for a simple reason:
- FREE ROM = 900 downloads,
- PAID ROM FOR £5 = 5 downloads - embarrassing
Why?
and one more thing...
My correspondence with mrbonsen, when I tried to help him out with the installation process is also interesting. About 10 emails with instructions to mrbonsen and also 10 emails of insults from mrbonsen. That means something....
So conclusion is simply... go back to your original firmware and I will give you your £5 back

and also 10 emails of insults from mrbonsen.

You did a great job and 900 downloads are impressive. i have a A2107A-H 1GHz 1GB RAM 16GB Flash - how come nobody is providing feedback or helping out in this development? Could there be a way to update.zip just the standard factory ROM? maybe that could be possible by doing a diff on the chinese and european source code? sorry i'm just a lamer looking to help out. any news from lenovo developers on the 4.1 release?
today is your cwm rom accessible for download for trial?

Ofcourse it is possible to get back the standard ROM just ask someone who still have a European ROM to do a copy by nandroid backup and you can restore this by centeCWM. So after that you will have a stock ROM with CWM but without calling feature.
I nearly finish another ROM with calling feature but this will be based on Russian ROM. I just need to get European system backup to do it same thing with European ROM.

ok so here are a few things you will need:
1x micro sd card (incase your data doesnt work to transfer files from computer or other device to phone)
1x a way to use micro sd card in computer (or other device)
Roms:
1x GB rom (the one i used is here)
1x ICS Rom (i used cm9 by entropy found here)
1x JB Rom + gapps (and i used scotts unoffical cm10.2 found here)
1x 3e Recovery (you can find this here and here is a video showing you how to use it)
***APP***
ROOT BROSWER ( or the one mentioned in the video)
ROM MANAGER
FRAMAROOT
ok so lets get to it... oh yeah
**************************** DISCLAIMER**********************
I TAKE NO CREDIT FOR THESE FILES AND APPS AND I ALSO AM NOT RESPONISIBLE IF YOU END UP
GETTING A REALLY EXPENSIVE BRICK NOR IS ANYONE ELSE BUT YOUR SELF
-----------------------------------------------------------TUTORIAL----------------------------------------------
ok download the files and install the apps from above
have them on your infuse (by any means you can i had to download them on my s3 and transfer them via sdcard)
ok
STEP 1:
- use framaroot to root your devicejust open it and press aragorn( i assume all infuses will have the same exploit name)
- reboot
STEP 2:
- open rom manager and click install recovery and select galaxy i9000 (they have the same partitions)
itll download a zip
STEP 3:
- follow the video for the 3e recovery installation posted above^
STEP 4:
- reboot revocery but powering off the device and pressing and holding vol up and down and power, once you see samsung come up release power
(once in recovery it should say 3e recovery at the top)
- select install update zip (vol up and down move from one item to the next and power selects it)
(your screen should go blank then come back up in clock work mod recovery)
- once in clock work mod recovery go to wipe data (say yes)
- then wipe cache (say yes) then go to advanced and wipe davlic cache (say yes)
- go back and go into mounts and storage and format system (say yes)
-go back select install zip from sdcard find the zip for the GB rom and select it and select yes ==HURRAY YOU JUST FLASHED A ROM==
- go back and select reboot device
STEP 5:
- once your phone boots up and is loaded go back into recovery (via three button method)
- then repeat the wipes and formatting
- then go to install zip from sdcard, and flash the ICS rom (warning you will get rainbow recovery, but you should still be able to navigate it)
- go to advanced and reboot recovery and flash it again
- once the second flash it done reboot device
FROM THIS POINT ON PLEASE REMOVE THE MICRO SDCARDS FROM THE DEVICE
STEP 6: (for now on the wipes and formating will be called wiping)
- once the device has booted in to cm9 reboot recovery again
- you will still have rainbow recovery but go and wipe it again
- and go and flash the JB Rom (if its one of scotts the first time the flash will fail just flash again)
- after the second flash it should auto boot into recovery (where you will see that it is fixed and no more rainbow)
- flash the JB rom once more and this time flash the gapps as well
REBOOT!
AND THERE YOU GO FROM FROYO (2.2) TO JB (4.3)

[Q] (Q) - running custom ROM but recovery is Stock

Dear NS forum - my colleague has crespo work phone.Last year I rooted and installed custom ROM for all my co-workers. The Nexus S user came to me with a problem; lately has many force closures and is very slow. I booted it into recovery & got the Android on its back with red triangle --> this is Stock recovery, right?
Not sure how CWM disappeared and got replaced by stock recovery.. but that seems the case. Am I correct that -
1. I need to load my PC with Samsung USB drivers to communicate with phone while in fastboot/download mode?
2. I need to install ADB SDK on my pc too?
3. I need to enter fastboot/download mode and flash a custom recovery?
Kindly help confirm the steps required, am I missing a vital step? Which recovery is best suited ... I have no preference over TWRP / CWM.
Lastly, I am very much out of touch with latest ROMs, appreciate any advice on a simple ROM, maybe 4.2 is best...
appreciate any help, I used to know all this stuff but I moved to Note 2 a year ago. Cheers.

Hey, I just read about Wug toolkit, is this a suitable tool for my issue ?....seems I could use it to flash a recovery for this phone which magically reverted to stock recovery .
http://www.wugfresh.com/nrt/

Hey folks, here I look forward to guide the Google Nexus S users of the XDA Community to go custom with their Samsung Nexus S. I shall try to put forth the most prevailing steps to make my way to your minds. Also I will use the fastboot method to accomplish custom during this entire guide. Before we put our hands on the device and begin with the instructions, I would like to state some general terms, for your ease. :good:
Terms & Understanding
* What is Bootloader and Why do we need to Unlock?
A bootloader is a boot initializing component which is generally locked by the device manufacturer to avoid any messing around with the OS. We need to unlock it for the same reason. Once unlocked it will allow us to change the boot sequence and modify the OS in accordance of our needs.
* What is Rooting?
It is a process of gaining root privileges over an Android subsystem. Rooting an Android device is easy in most cases. If you will to Install custom ROMs, kernels, other patches or addons to your Android device, rooting is what you will need. It can be achieved in two ways; either by manual method (using fastboot) or by automatic method (using toolkit or software) . Here, I am going to follow the manual method by using fastboot commands.
* ClockworkMod, what is it?
In short, CWM; It is a secondary recovery system created by Koush (Koushik Dutta), which adds enormous features like wiping partitions, flashing flash able .zip files like ROMs, kernels, patches etc to the stock AOSP recovery. Visit ClockworkMod website for more.
* What does Custom ROM means?
These are the aftermarket Android firmware which are not official supported by the OEM (Original Equipment Manufacturer). They are made available to the Android public by Android developers and contributors all around the world. Custom ROMs are either built from Google’s source code i.e AOSP (Android Open Source Project) or are modified versions of the device manufacturer’s ROM (Stock ROMs or Factory ROMs) with additional tweaks and extend functions which are not delivered with the Stock ROMs. Some of the popular Custom ROMs include CyanogenMod (CM), Android Open Kang Project (AOKP), MIUI, Codename Android (CNA), Oxygen, ParanoidAndroid and many more.
* What is Custom Kernel?
A Kernel is a bridge between the applications and the actual data processing done at the hardware level, In simple words, it is the communication between the hardware and software of an Operating System. In Android world, Custom Kernels play a vital role since they provide the users with several features including changing CPU frequencies, modifying the boot sequence and boot scripts and other features too.
* What are Google Apps (Gapps)? The name speaks for itself. Gapps are Google apps for Android available in flash-able zip format. Most of these applications can now be found and updated via the Google Play Store.Some of the apps include the Google Play Store itself, Google Talk, Google Sync (for adding and synchronizing Google accounts), Google Backup Transport, Car Home, Gmail, Google Maps, YouTube, Google Search, Google Voice Search, Google Music, and Google Docs. In some Custom ROMs, the Google Apps are included. These are usually stock ROMs, smaller or less-common ROMs, or those from areas where intellectual property laws are less commonly obeyed. But many AOSP ROMs, most famously CyanogenMod and AOKP, do not include the Google Apps due to licensing issues. They are after all proprietary code owned by Google and not included in the Android Open Source Project.

6. Your device shall now be in recovery mode.
* Flash using CWM:
"advanced" > "Wipe Dalvik Cache"
"install zip from sdcard" > choose zip from sdcard" > now browse and select the kernel zip package that you placed in your storage root during step #3.
Select "Yes".
Your Kernel will now flash to your OS and replace your current kernel.
When it has successfully flashed, select "reboot system now".

[Q] Nex S killed while rooting

I followed this guide [GUIDE] MAC Rooting Nexus S (http://forum.xda-developers.com/nexus-s/general/guide-mac-rooting-nexus-s-t878446) until point
6) Open ROM Manager and choose "Flash ClockworkMod Recovery". At this point you are all set .

As Rom manager rebbot doesn't work, I installed Root checker and it told me thet the phone was not rooted properly. So I decided to follow another guide [HACK] Superboot Method for 2.3.2 (GRH78C) (http://forum.xda-developers.com/nexus-s/development/hack-superboot-method-2-3-2-grh78c-t927838).
Now the phone doesn't work! In other words when I press the power button the Google logo screen remains and Android doesn't start.
If i hold volume up and power button I gain the following:
Code:
Fastboot mode
Product name: Hearing
Hw version - rev 52
Bootloader version - I902XXLC2
Baseband version - I902XXKI1
Carrier info - EUR
Serial number - 3035...
Lock state - unlocked
and I can choose:
Code:
[LIST]
[*]Reboot bootloader
[*]Reboot
[*]Recovery
[*]Power off
[/LIST]
I think that the problem is that the phone is looking for the file "install-recovery.sh" that I renamed into "install-recovery.sh.old".
How can I reanimate my Nexus S?

I'm going to put it step by step using the Nexus root tool kit (NRTK)
1. download a flashable recovery of your choice (CWM 6.0.4.3 Philz 6.19.3 or TWRP 2.7.0 or higher on all these)
2. download the kitkat rom you want to install
3. download the Gapps that match the rom you chose ( if a 4.4.2 rom get a 4.4.2 gapps if 4.4.4 then 4.4.4)
4. boot your phone into bootloader / fastboot
5. connect your phone to your pc (it should recognize it)
6. open your NRTK and go to the advanced section and choose to temporarily boot custom recovery (this will be TWRP 2.6.3)
7. ON YOUR PHONE select mount usb
8. ON THE COMPUTER open the device/folder for your phone and create a new file on your SD card ( I called mine " !zip " this kept it ontop of the list of files) and copy the recovery, rom, and kernel to this folder.
9. ON YOUR PHONE unmount usb, return to the main menu screen and select install, find that folder you made and select the recovery zip that you copied and swype to install
10. after it installs (10seconds) return to the main menu, select reboot then reboot recovery ( you may get a warning about not having a rom or su, ignore both)
11. now you are on your KK compatible recovery (nearly there)
12. No matter which recovery you chose find the section to wipe or format your phone (DO NOT WIPE OR FORMAT YOUR SD CARD !!!! this will wipe everything off your phone and may make it hard / impossible to restore) and ONLY wipe or format system, cache, and dalvik partitions. On philz there is an option to wipe to install a new rom (this is a onestep version of the above)
13. return to the main menu page and select install, choose your rom and install, then your gapps and install ( if on TWRP you can select both by choosing the option to add a zip to flash)
14. the moment of truth, now that you have flashed both rom and gapps, you need to return to the main menu and select reboot and reboot system...
15. assuming you did all of this issue free, you are free to enjoy your phone..
*if you don't have your phone recognized by your computer / NRTK, you need to follow the instructions for NRTK to get the correct drivers for your computer
**if you are not clear on what you are doing, ask before you make a mistake
***Your custom rom will be pre-rooted, so no need to try to root it

Can someone help me to understand this custom ROM installation?

Hello, I'm new here, I've been dealing with certain ROM mods for a little while. My test device is an old Samsung Galaxy S4 mini (GTI9195). Now I've been sitting for a few days trying to figure out how to bring my device up to date as best as possible. Lineage OS seemed the best to me. Unfortunately there is no officially confirmed software for my device directly from Lineage, which is why I looked elsewhere. I came across this thread on XDA: https://forum.xda-developers.com/t/...520-r890-unofficial-11-0-0-lineageos-18-1-for -s4-mini.4189967/ . The user arco68 is, so to speak, the boss among S4 mini modifications. Unfortunately, I can't find exact instructions anywhere (especially for the recovery) on how to install all the packages correctly. That's why I researched. I was able to record various steps, but cannot determine if they are correct. Can someone on this forum please help me? My steps:
1. Turn on developer options
2. Turn off OEM encryption (if available)
3. USB debugging on.
4. Download and install Android platform tools in Path
5. Download and zip Magisc
7. Put the phone in bootloader/fastboot/download mode (volume down + home)
8. Flash Team Win Recovery Project (or other custom recovery).
9. Restart phone and boot into recovery mode (volume up + home + power)
10. Erase all data
11. Copy Google Apps to Phone (Optional)
12. Copy Lineage OS (or other custom rom) to phone
13. Install packages one by one (OS first)
14. Reboot device
15. Wait and set up

Okay, First of all requirement-
A portable sd card- Because after flashing twrp, you might face issue where you can't access internal storage from twrp. That's because the phone might be encrypted. You have to decrypt it by flashing a "disable dm verity- forceencrypt.zip". In this case, you might not be able to transfer files from pc when booted into twrp. So, It's a smart move to insert a sd card containing all required files before to avoid these problems.
Another requirement is samsung drivers installed in pc. I will attach that file.
Follow these steps -
1/Unlock bootloader -Go to developer options. Turn on oem unlocking. It will tell you that you're going to loss all data. Proceed. If it doesn’t tell you anything, then there is definitely some extra process to unlock bootloader of your device.(search on internet)
2/Download your phone's official firmware in pc- it will help you if anything goes wrong. Search " Sm fw" on google. Go to first site. Create an account. Search the model number, Download a firmware that matches with all your device's information in "About phone".
3/ Download the lineageos rom and twrp recovery for your model. Then install device info hw from play store to check bits(32/64). Search open gapps. Go to the website. "arm" is for 32 bit & "arm64" is for 64 bit. Select which matches to your device’s bit. Then select the android version of the custom rom. Then select "Pico". Download the file. Next, download latest magisk 25.2 from github page. Rename the apk file to "magisk.zip" Move rom,gapps, magisk.zip to SD CARD. Keep twrp in pc.
4/In pc, download latest odin software. It's an special software for samsung download mode. (There is no fastboot mode in samsung)
5/Boot your device into download mode. And connect with pc.
6/In pc, extract the twrp file(If It's in zip format). Open odin software, Go to options, turn off auto reboot. Now select "AP" & select that extracted twrp file. Click open. Then hit start button.
(Note that most of the samsung devices can't boot stock rom after flashing twrp. So you have to flash custom rom to boot your device. Follow the next step)
7/Boot into twrp wipe>format data>type "yes". Press home button. Install>Select storage>SD card>select the rom.zip. Then add more zips> select the gapps.zip. Again, add more zips> select magisk.zip. After all, swipe to flash.
After installation, reboot device.
What if anything goes wrong?
Extract the stock firmware that you downloaded from sm fw. Connect device in download mode. Open odin, select AP,BL,CP,CSC file one by one. Start flashing. You device will be alive again.
