To those who have already made a backup of their ROMs usinf TWRP or CWM: were you able to save the backup file/image in the external sd card? I read somewhere that Android 4.2 backups are saved in the internal storage. Can someone enlighten me please? I'm a little confused. :confused: Thanks! :p

Hi Friend, What's the version of your rom?
[Lenovo A850] boymatikas:
Im using stock rom, ROW_S116. Do you have a recovery installed already? Where does it save your backup?

[Lenovo A850] GreatApo:
- CWM: Backups are saved in the external SD card. (if you have change the internal SD with the external in the rom, this does not change it in the recovery). There are some recoveries with an option to save the back up in the internal storage.

- To see if you have a recovery you can close your phone and then open it pressing (all): power button, volume+, volume-
[Lenovo A850] boymatikas:
Does this apply both for CWM and TWRP? Do both these two save the backup in the SD card? Which one do you recommend? :)

[Lenovo A850] GreatApo:
Nice question, well i am not sure about TWRP (i changed the above reply). Anyone interested can take a look at this post which seems to contain more info.

What i am sure is that both recoveries make a folder named "clockworkmod" or "TWRP" in your storage and a "backup" folder in it with your backups. Your backups are stored in separate folder each, with a date-time format as name :)

I am a CWM user since i bought a Xperia X8 (so ages ago :P) , i tried TWRP once and i can't say it is not good. TWRP is touchable with a nice UI but i got some errors using it and i am too familiar with the CWM to let it go.

I suggest you to use whatever feels better in your hands...
[Lenovo A850] boymatikas:
Thanks for the info. The only reason why I consider TWRP is because it shows you the estimated size of the backup. :D

I made a backup of my ROM (system and data/apps) using TWRP. I want to test my backup file so I uninstalled 1 application from my phone. I went to boot in recovery and restored in TWRP. I was hoping to see that application (game) to be restored but lo and behold, the app still isn't there! I thought that it was just a bug in TWRP so I flashed CWM. However, the result was the same! The app that I removed (which was includes in the backup) wasn't restored. Do you guys have any idea on what I did wrong? :confused:

I'm using S123 but I have problem identifying if it is ROW or CN because it is not specified in baseband identification.

Please can anyone help? I need to know in other to make the right choice when flashing my CMW. Please
[Lenovo A850] GreatApo:
It should have worked...

Make sure that the app is in the internal storage of your phone and test again.

Have you searched in the build.prop? (you may found the version there, it is located in the "system" folder)

I do not know if flashing the wrong recovery will stack you in a bootloop or just not be able to enter the recovery.

If i were you i would try to install the ROW version (unless you are from china :P)... BUT i would have been prepared to lose all the data in the phone so...

Backup what ever you can in your SD:

- use titanium backup or any other backup app

- extract your contacts in your SD card (the last thing you want to lose is your contacts) or make sure you can see them from you google account here (you need to synchronize them)

In case you stack in a bootloop or sth you must also be able to flash a new rom (video here)...

Better prepare for the worst :P
[Lenovo A850] Perock:
This the post I'm referring to
[Lenovo A850] boymatikas:
Yes, all of my apps are installed in the internal storage linked in the ext2 partition of my sd card (I'm using Link2sd). All of my apps have been restored except for the single one that I uninstalled to see if the backup can restore it. I'm puzzled by this actually. :sly:

[Lenovo A850] GreatApo:
Yes i wrote that post :P

If you can't see the ROW or CN from the Settings->About phone->Version Infos->Baseband version, search in the build.prop in your system folder...

When you taking a backup check the log... i do not know if recovery searches for ext2 and ext3. It will write "Back up ext2" or "Ext3 was not found"...

Backups work. Somewhere else is the problem ^_^
[Lenovo A850] boymatikas:
I agree with you, I think the backup works because I can restore everything except for the test apps that I uninstalled. I'll look for the problem and get back on this thread once I resolve it.
[Lenovo A850] boymatikas:
I tried to do another backup using TWRP. Unlike my first backup where only the system, boot and data were selected, I also backed up the preload. After completing the backup, I did a reboot and INSTALLED a new app. My idea was, if the backup I made was correct, the newly installed app should be removed after the TWRP restore because it was not included in the backup. So, I went to recovery and did a restore. When my phone went to reboot, I immediately checked if the app is still there. Voila, it's gone! So I thought, I finally got to backup my phone correctly. However, I had to do another test. This time, I need to see if an uninstalled app that has a backup can be restored. I underwent the same procedure, went to recovery and did another restore. However, this time, the uninstalled app with a backup DID NOT restore. And that's what puzzles me. Can anyone help me here? Can anyone do a backup, then after that, uninstall just 1 app (you may want to back it up in Titanium Backup Pro in case it doesn't restore) and see if we get the same result? I do not think I did anything wrong with my backup because it was able to restore my original setup when I installed a new app; but it couldn't restore my original setup after uninstalling 1 app. I'd appreciate anyone who can help me with this. Thanks!:laugh:
[Lenovo A850] Perock:
I finally flash the cmw using the ROW version but after backup I saw only four files in my clockworkmod folder. boot img 6MB, recovery img 6MB, system. ext4. tar 00.B, system. ext4, tar. a 11KB, only four folders. I think something is missing. If I should repeat the flashing using the new image in post above or better still using the TWRP do I need to wipe out or delete any before re-flashing or I should just go ahead with process from the beginning ?( i.e using mobileuncle). Please help
[Lenovo A850] boymatikas:
Are you sure you were able to make a backup (by going to backup and restore > backup)? I used CWM too, and my total backup size was more or less 3GB. I used both recoveries and both worked fine.

Update on my previous backup dilemma: I found the problem. TWRP and CWM does not backup the ext2 partition (I'm using Link2sd) as pointed out by GreatApo. Meaning, the app becomes broken when you uninstall it because the linked file in the ext2 partition cant be backed up. Make sure to remove the link in Link2Sd if you want to have a "full" backup of the app. Also, as long as you dont uninstall the app, you can still restore the app because the file in the ext2 partition is still intact. Or you can just use Titanium Backup Pro to back up linked apps. :D

By the way, anybody tried Xposed framework on our A850?

Thanks for the information. During the backup I saw that the backup for the images i.e( boot image and recovery ) was completed but data on was not able to be backeup. Like how long did it take to complete the full backup? I'm suspecting that the backup process was complete. I spent up to 20 minutes
[Lenovo A850] GreatApo:
Use titanium back up... i do not know why you have problems backing up... i really believe it may be an app2sd problem...

[Lenovo A850] GreatApo:
20 mins for a backup is too much... i really have no clue for what is going on...
[Lenovo A850] boymatikas:
I figured it out already (you can see ot in my previous post), it's because of the linked files using link2sd, just like what you mentioned. :D

[MENTION=5969636]Perock[/MENTION]

I also experienced longer backup time using CWM, but I was able to backup all, even the data. I'm not sure why this happens to you. Try TWRP and see if you emcounter the same problem.

[Lenovo A850] boymatikas:
Oh I see. Thanks for the info. What modules work on your A850? Do you have recommendations? I think gravity box won't work. Xposed Additions might.

Edit: I just installed Xposed framework and Gravitybox module works just fine. :p
[Lenovo A850] GreatApo:

[Lenovo A850] boymatikas:
As far as I know, you don't have to do anything but tap on restore in TWRP recovery. I've done this a couple of times and I was able to restore may backup. Do you think there's a possibility that maybe you weren't able to make a complete backup?

[Lenovo A850] boymatikas:
Are you already stuck at the Lenovo logo? If that's the case I think you'll be needing to flash a rom. However the data in your internal storage may already be gone. I think you can try a factory reset since you've got nothing to lose at this point (assuming that you are already stuck at the lenovo logo).

Edit:Try to power it on a couple of times first before you flash a rom. Who knows, your phone may still be able to boot to the home screen.

[Lenovo A850] boymatikas:
I'm not really sure which version is the best but mine is s116. This is my rom's version since I got this phone (I didn't use OTA). I heard s121 by linerty is the one that can save apps to sd (I'm not sure if this is stock and officialy released by lenovo). I haven't tried it though. S127 on the other hand also saves in sd card but is an official update from lenovo. You can check needrom.com and search for lenovo a850. I believe there are plenty of roms available in that site including the s121 ;)

short version: can i use stock recovery to flash a official lenovo update such as S127 ?and will doing so fix a soft brick?

long version:i soft bricked my lenovo a850, it came stock with chinese and no gapps and with super annoying full screen pop up ads (in chinese) other wise a good phone,i wanted to get rid of these ads so i used frarma root and successfully rooted it,then right away i downloaded online nandroid backup with my other phone and sent it to my lenovo via bluetooth,i made a back up(which now seems pointless however every rooting tutorial ive read said to do this) then i downloaded root system app remover with my other phone and transfered it via blue tooth to my lenovo,the ads that popped up had a weird cross type symbol so i looked for what ever installed app had that symbol and i deleted it,this apparently was a mistake lol as i had a error pop up immediately after doing this saying the process.android.system (or something like that) has stopped,i rebooted my phone to see if it would go away and was stuck at lenovo logo...i then tried hard resetting it and clearing cache over and over rebooting it every time to see if it worked,to no avail i might add...i have no custom recovery and cant seem to get the drivers installed correctly as flash tool wont see my phone,can i use stock recovery to flash a official update from lenovo such as S127? please help me my wife got this phone for me with the last of her money and i feel like **** for breaking it...
[Lenovo A850] GreatApo:
First of all, your phone can be repaired.

I do not know if you can flash a zip from the official recovery, try accessing it (maybe with the volume up or down button with the power button) and see if it has an option to flash a zip file.

What you have to do is to make the drivers for your phone work on PC. Try again, there are a lot of videos showing how to do it. If you have windows 8 they might not work... if you can't get it working on your computer try an other one (friend's maybe?). Install the drivers and open the device manager to see if the phone is regognized corectly.

After you have the drivers installed, Flashtool will make the work for you. You can either install a recovery and then flash your backup or you can directly flash a new rom (better install a new rom).

This is a very good tutorial to start with...

There is an other way to go... using ADB. But you should have the back up in you PC (or download one) and restore it with ADB. See here.

And when you have a working phone, the first thing you should do, make a back up, install a recovery or get your PC drivers to work.

Good luck!

Help CN or ROW

Hi I do not know which firmware to use ROW or CN?

Baseband: A850.V13, 09/06/2013 17:49

Build Number: A850_S203_140208

OS: Android 4.2.2

The boot logo is chinese and some of the apps but I changed the language to English & without google apps/playstore.

I want to flash gapps but I need to flash recovery first right? In the build.prop there's a line "ro.product.locale.region = CN" so I'm suspecting that I need to use CN firmware but I still need to confirm because I'm afraid I might brick the phone.

Hey there Keval3393,

You can use any of these recoveries, it works in A859 Lenovo phone, just install first the "MobileUncle MTK Tools" from the playstore or use the attached one and update the recovery from there in a "Recovery update" line, just put it on your sdcard or internal storage to locate in the mobileuncle.

[Lenovo A850] irfanadli97:
Maybe you may will just stuck on your stock recovery since there are rumours that MAJORITY (..yep) of these phones shipped are meant not to be flashed except ROW. You may be using a generic chinese smartphone that does has the same, better or worse specs under an A850 plastic housing.

That answered your question somehow. Now read my verily-long-short-enough-to-be-a-review feelings about why we face these problems.

Chinese smartphone manufacturers (and possibly other smartphone manufacturers too), are trying the best to prevent firmware change in any way possible, because they are defending their marketing asset, that is their modified ROM with ****loads of bloatwares, which.. "WOW I CAN SHARE ANY FILES WITHOUT BLUETOOTH, SO BLAZIN' FAST WIF THIS APP"...for normal users, but..."I FRIKIN H8 DIZ BLOATWAREZ I WANNA REMOVE IT!!!"...even for me and most power users (users that do more than just using the phone in the phone way). Well in reality standard users are the main asset for this companies, which you can see by yourself by just looking to an average schoolgirl that uses Galaxy S6 Active just for Instagram, they are bound to stock ROM by manufacturer and they want to keep it that way in any impermeable walls possible, unlike Google.

Chinese manufacturers are too lazy to release the source code for the firmwares for every phones they release, because they don't wanna deal with a hoarde of Super

SU

geeks who want answers in "why I cannot apply root.fs in this firmware Axxx-20xx?", "Please make support for this Superuser version!", nope they're not gonna reply all that stuff because simply they really cannot ENGLISH.
