v2.3.5a
- Some of the Google apps/framework files seem to be broken somehow. Replaced them with older version that seem to work. Update from GooglePlay if you need. Will try to update them in the rom, but for now this should be fine.
————————————-
- Updated Russian, Polish and Hungarian (approx 95%) – new version of IdeaFriend is not translated
- Updated Italian, Spanish, German and Portuguese here and there
- Updated GoogleApps and GravityBox
- Update kernel to S150
- Optimized png files in almost all apps
- Revised scripts and replaced sqlite3 binary with faster one
- Scrolling in lists and animations should be smoother
- Deleted line in build.prop that disables JIT compiler. If anyone need it can always add it again.

Update Lambda v2.2.1 to v2.3.1 (CWM/TWRP)

Due to several request, this flashable CWM zip updates v2.2.1 to v.2.3.1.
User settings and installed aps should stay in tact, but keep in mind there might be some mistakes. I tried to include all changes.
Tested with clean installation 2.2 -> 2.2.1 -> 2.3.1, so there's always possibilty it doesn't work for you with all installed apps.

Update from V2.2 to 2.2.1 (Patch)
- Fixed* callerId matching issues, however it's adjusted for Bulgarian GSM numbers, so it might not work in your country. Credits to C3C076 from xda!
- Chinese city names removed from contacts and call logs – not displayed anymore
- Fixed problem with initialization of Sony Clear Audio in config files
- Standard launcher modified, theme is removed. All needed icons/styles are encapsulated in the launcher.
- Added two additional and helpful options in power menu – Reboot and Recovery
- Boot/shutdown animations changed to Lenovo
* You will need to manually remove all contacts and import them again in order to activate the fix. Also remove all message threads. After that new ones will be grouped correctly
Update script tries to keep all user settings, so your launcher screens and wallpaper should be preserved. However, if you flash the update over a fresh V2.2, you will still need to remove the lotus and missing widgets from launcher screens, then change the background if you want. As always, make a full backup, just in case. Script wipes cache partition and dalvik-cache, so first boot will take time. I will address other issues in future version, but it might take longer time to release it. So far updates were very frequent, but as the ROM gets mature enough, it doesn't require many changes. Please report any problems you encounter, they are taken into account.

LenovoSystemUI-mod-CWM (CWM/TWRP)
- Updates SystemUI with 1% battery mod
- Updates to empty SIM display mechanism. Indicators for unpopulated slots are now hidden. Credits to C3C076 from xda.

Install ROM:
V2 and up
Download desired zip and copy on sdcard.
You need a modified recovery to install the firmware and updates. If you have it already, proceed to step 3. If you don't have, follow these steps:
1. Download Lenovo drivers, unzip the archive. Turn off the phone and remove battery. Open device manager and connect the phone to PC. Watch for new devices. It will be displayed as МТ65хх Preloader. You need to be quick, because it will dissapear in some second. Click on it with the right button and select update driver. Point the wizard to the driver folder, it will install the correct driver automatically.
If it doesn't work with removed battery you can try to power on the phone and turn on developer options in settings or enter meta mode – hold Volume Down and Power buttons. Then connect the phone to PC again.
2. Download and extract Recovery zip and Flash tools. Run Flash Tools, click on DL DA All With Check Sum, load the scatter file located in Recovery folder, uncheck Preloader and hit Download (F6). Remove battery from phone and connect it to PC. When done, a green circle will appear.
3. Enter recovery mode – hold Volume Up, Volume Down and Power buttons until you see the logo. Make a backup of your current system first. Install new zip.
※Please make a backup of your device before installing or updating ROM

How does the 2.2.1 rom match up with the elotalk mod rom I had put on my phone when I bought it, im not that clued up on flashing roms so dont want to risk screwng it up if there is no need. Thanks in advance
Hello Infrared,
I was hoping you could help me.
I'm making an flashable cwm rom based on the etotalk mod rom.
I was wondering wich file to edit so i get what you did with you patch..Updates to empty SIM display mechanism. Indicators for unpopulated slots are now hidden.
I also want to edit the settings menu. The etotalk rom is a port from a ZTE rom.
In settings there is a option to called ZTE Hotline and i want to remove it.
I hope you can and want to help me.
When i publish my rom i will surely give you credits.
BTW I think your rom is great thanks so much for it.

Hi and sorry that I can't help you, but it's impossible to describe everything needed in a simple post at needrom site. You might be able to do it yourself, but you have to read a lot to understand key principles in producing a cwm-flashable rom. There are guides on the internet for that. First of all you can unzip the 2.2 rom, but you should learn how to write/edit updater scripts, what folders you need from the original rom. For the unpopulated slots and battery mod you'd need to know how to deodex apps, how to decompile them, then edit smali files, compile back, put correct signature and odex the application. Too much things to decribe in a single post.
I had Etotalk ROM that was developed from ZTE and the worst thing is not having sim tool icon to access network specific functions. I installed ROM from Infrared, it is very stable and even yesterday,I deactivated phone-city addresses from my contacts. I am satisfied with the phone now, the only issue is I cannot use NoLED app, the changes are not saved like it was the case with Galaxy S6102 that I had previously. So I can't get alerts for missed events. Anyody that can help me with that?
Simmymma,
I also had etotalk installed on both my A820′s. I’ve been experimenting with various roms for 3 weeks. In my opinion Infrared’s work, found here, is the only way to achieve anything close to a full, original English OS on this phone. Stability has not been an issue, usability is the key for me. I’ve not remotely missed etotalk rom.
Thanks very much, I tried loading v2.1 through CWM after factory reseting and wiping dalvik cache but it came up with an error, and when I tried restoring my nandroid backup I got an MD5 mismatch error, any idea where im goin wrong. Total noob haha
There was a system update from Lenovo I guess, around 394MB. I thought this was an upgrade to 4.2.2 but I am not sure if is okay to install the way it is. It would undo a lot of customisations already made by your ROM. And by the way, I realised the upgrading could not be done as the system returned error message: "failure to verify signature",… "install aborted". Could you please develop for us this and help us on how to upgrade to the latest version of OS? So far, I am very grateful for your diligence and good work. Thank you!
I haven't tried myself, but I guess update is not possible on a modified ROM. However, if the update succeeds, it will wipe most of the customizations if not all. It will also bring back the factory recovery. The only way for upgrade would be when the author of the ROM updates it. Otherwise, you can install stock S138 and update it to S139 from the phone menu, or install S139 directly. I don't get updates, because I've forbidden OTA updater from accessing the Wi-Fi. Since my touchscreen is broken it will be very hard to enable it and download the update, but I will try.
Simmymma,
It would help to know what error CWM produced.
Did you try to move from Etotalk to infrared v2.1 straight away?
Honestly cant remember the error msg, and yeah i tried etotalk to v2.1 straight away, should I have tried v.1 and upgraded. Ill try again when i have a minute and let you know. thanks for your help
Guys tell me i on official stock. How to update with a stock rom?Please make a guide…
Hello infrared.
I know how to deodex sign decompile compile etc just need to know wich file to edit to hide the unused sim slot.
Hope you can help.
Thank you
Aah, that's cool.
It's in LenovoSystemUI. Search for [HOWTO][MTK6589] Autohide mobile signal icons for empty SIM slots in xda, there's a guide about this.
Hi, I have a problem with two operators here in Brazil, the course takes 3GB signal but does not connect to LIVE and the frequency 850MHz, is to change the frequency on the device?
Can anyone help me?
Thank you.
Simmymma,
I can’t definately state that one method works over another for sure. I can only speak for the route I came for logical reasons. The Etotalk ROM is not based on a Lenovo ROM, rather a ‘similar’ ZTE offering if memory serves correctly. The Infrared ROM is based on pure Lenovo stock. Thus the updates for Infrared also presume a Lenovo base. It doesn’t surprise me that you would encounter a mismatch.
I’d physically flash V1 and start from there. It worked for me and I’ve got two happy campers with nice stable A820′s based on Infrared’s sterling work.
Like use flashboot? Cheers bud, just a bit wary incase it all goes wrong and I have to put the stock image on. Ill fiure it out haha
Infrared,
How did you block net access to OTA?
DroidWall app.
