MOBILE FAN 42 Report post Posted September 21, 2013 Hi, I got Lenovo A820e from china this week. Its a CDMA+GSM. The phone is from China Telecom and doesnt have Google Apps. I have rooted the phone using Framaroot. In oder to install Google Apps, I am able to get many zip files which can be flashed using customer recovery like CWM. However, to install custom recovery, I need to go to Fastboot. But my problem is that I am unable to get into fastboot.By pressing Power + Volume Down I get to a menu where these options are listed -0. Board Test1. Current Test2. RF Test3. Test Flow4. SD Update5. Erase Userdata6. Format Internal SD7. Copy Pre-Source8. RebootAnd if I press Power + Both Volume Buttons, I get the menu like below -Android System recovery <3e>Reboot system nowapply update from external storageapply update from internal storageapply update from ADBapply update from cachewipe data/factory resetwipe cache partitionbackup & restoremount & storageCan anybody help me here on how to get into fastboot mode ? Or is there any other way to install a custom recovery ? Share this post Link to post Share on other sites
a1cellsolution 84 Report post Posted September 21, 2013 Use command "adb reboot bootloader " to enter fastboot mode and flash custom recovery is evdo data working on your A820E cos as soon as the evdo appers it gives a force close error & network bars dissappears Sent from Xiaomi Hongmi Share this post Link to post Share on other sites
MOBILE FAN 42 Report post Posted September 21, 2013 Thanks for responding quickly Jagjit Singhji. When I try - adb devices I dont get the phone listed there. From resources on net, I found that the drivers get loaded when the phone is connected to laptop during fastboot mode. Since I cannot get there I am unable to load the driver. Exactly when should I connect to laptop to issue the "adb reboot bootloader" ? However, I managed to install most of the drivers. Only one node - "USB Device" remains yellow in Device Manager. If you have the USB driver, I would install and try this. I have not yet tried to connect using EVDO. Let me try right away. I will update soon. Share this post Link to post Share on other sites

MOBILE FAN 42 Report post Posted September 21, 2013 I tried for about 40 minutes. Unable to connect using EVDO. I still have to try on EDGE. Too much fight for everything. But first thing first - I need to start Google Apps. For that I need to be in Fastboot mode. Plz. help. Share this post Link to post Share on other sites
MOBILE FAN 42 Report post Posted September 22, 2013 connect the phone to pc it should show a cd rom install china telecom software it will install all the required drivers enable usb debugging try adb devices first if it connects than try adb reboot bootloader I could have done this. But before I read this, I already gave the phone to a friend. He used Flash Gorden and flashed a CWM Recovery. Now the phone is not moving beyond Lenovo Logo. Also when booted into recovery, it still shows the stock recovery. Then he wiped the cache and partition and restored the backup. It shows that the restore was successful but still on reboot the phone stuck at the logo. Now wiping the partitions, shows error that it couldnt mount. It seems, I am in a deep trouble. May be the phone is bricked permanently. I would appreciate any help. Share this post Link to post Share on other sites
MOBILE FAN 42 Report post Posted September 30, 2013 I was able to get back the phone to life. Flashed a rooted ROM with Google Apps and everything is working. Except- Unable to switch on either Reliance or Idea APN. The phone is not connecting to internet except on WiFi. Any idea, how to do this ? Share this post Link to post Share on other sites

sadiqu 0 Report post Posted December 17, 2013 Hi, I have also an A820e. Got to the same point. I've installed a ROM with GApps and got everything working except I can't get 3G data, only GPRS. I think it's ROM related. Have you been able to find a solution? Share this post Link to post Share on other sites
sadiqu 0 Report post Posted December 18, 2013 It seems that Lenovo A820e doesn't have the 2100 band which is required for 3G communication in Europe. The way I was able to activate data in the ROM that has the google services is by introducing the following code in the dialer: *#*#4763#*#* After this a message telling me that the data has been started appeared and I was able to control. Also before this I made a change in system/build.prop to default the network to gsm. I've added: ro.telephony.default_network=1 (Should be rooted to have access to this. I've used Root Browser) Hope this helps. Share this post Link to post Share on other sites
MOBILE FAN 42 Report post Posted January 7, 2014 When I dial *#*#4763#*#*, it allows me to toggle gsm data by showing a message on screen. But if I change the settings from Sim Settings to use gsm data, I get error - "Unfortunately, the process com.android.phone stopped" and then, signal of gsm and CDMA goes off in the status bar at the top. I must have to have CDMA data to use phone Sent from my SGH-I9000 using Tapatalk Share this post Link to post Share on other sites
sgiitk 32 Report post Posted February 13, 2014 (edited) What is the latest scenario regarding running fastboot and adb under Windows 8 (8.1 specifically). Have these been sorted out. If yes, the sources / versions which are compatible. Specifically, I want to get into my rooted htc One to unroot it. I hear that fastboot does not work.

YourZgapps... Zip is the file that you should be able to find on xda. That would work for you. If not, I will try to send it to you Edit : btw, the latest update is 130916. Why don't u use the latest one? Sent from my Lenovo A820e using Tapatalk Edited June 16, 2014 by MOBILE FAN Share this post Link to post Share on other sites
