I have a problem with one of my Lenovo A830 phones.
I bought it from Etotalk, so it came rooted, and with their custom version of the Lenovo Stock ROM and their custom version of CWM 5.5 installed.
I tried formatting my SD card and then doing a factory data reset from within the operating system. (I was intending to install MIUI V5 after rebooting into recovery).
However, on rebooting, the device is now caught in an infinite boot loop, and I am not able to boot into recovery mode (by holding down power and both volume keys). It loads the initial splash screen, then shows a few seconds of the Android character and some whirring cogs before rebooting.
I am able to boot into Factory mode (power and volume up) or Meta mode (power and volume down). Factory mode has a number of options, but they are all in Chinese characters, which I am unfortunately not able to read.
I did notice that my SD card seemed to be write protected when I tried to format it in my computer and to copy on the new ROM - I solved this by putting it in a different phone and reformatting it. I wonder whether the factory reset process has write protected something it shouldn't have?
Does anyone know how I might best proceed? I've been digging around on the forums, and tried a few things, but there's nothing which seems to provide a coherent solution for this problem.
I've got the latest Android SDK Tools, MTK Droid Tools 2.4.8, SP Flash Tool 3.1312, some additional ADB drivers (120827 v3.7) that I'm not sure how to install, the latest MIUI V5 ROM (3.8.16), and the latest stock Lenovo ROM (S118 from Need A ROM, just in case I need it).
Maybe different SP Flash Tools version?
I had trouble using SP Flash Tools v3.1312 with A830. Once I switched to v3.1304.0.119 I was able to flash both the original ROM and the custom MIUI one without serious issues. I'm unable to post the download link but google it.
One other thing is that when connecting the phone, it usually loads the something something Preloader driver, which is no good (even if it gives you Download OK). When attempting to flash either ROM, try pressing both the power and volume up buttons while connecting the phone (after pressing Download), only way it worked for me.
Good luck!
I managed to sort this out quite simply in the end!
On the Lenovo A830 (and presumably other Lenovo Android phones?), you enter recovery by pressing power and then pressing volume up / down together after a short pause. The short 1 - 2 second pause is important, because if you try and press them at the same time or in quick succession it doesn't seem to work.
I then installed MIUI V5 from the SD card followed by Google Apps after a reboot. In order to get MIUI to install, I had to remove the assert check at the top of the update script, because this seems to erroneously check for the A820 (even though there isn't currently a port for this device?). It's working excellently with two exceptions - I am unable to select the SD card as a storage device, and Google Play store is not searchable (it causes a Force Close).

Hi I had similar "reboot loop" problem this morning after a phone factory reset.
I have no idea how I solved that but the following was the steps I tried:
1. Install the MTK6589_PdaNET_ADB_VCOM_Drivers. Skip the USB connection during setup. Start the PdaNET after setup finished.
2. Insert battery inside the phone and connect the phone with the computer by USB
In my case, the phone reboot loop once, and the lenovo screen appeared in the second restart. The phone hanged. I unplugged the cable, took out the battery, insert the battery again and start the phone normally again and it is working now.
I recommend installing the recovery rom after you have fixed the phone.
Goodluck
Hi guys!
i really need some help..been dealing with this for 1 month now..anyway tablet info first,
-Cherry Mobile Fusion Bolt (Philippines)
-Jellybean 4.1.1
-not rooted (they said it was pre-rooted, i was gonna root but then problem happened)
last few weeks, apps just randomly crashes and some system processes stopped..so i tried hard reset (no choice)..
after that, everytime i turn it off and on again, i need to do the hard reset because i am always stuck in boot loop..
now i tried to turn it on again (doing hard reset) but the "recovery" no longer appears..its just a flash of light then goes black and so on and nothing happens..tried different key combinations - nothing......plugged to a pc - detects the driver..
please, what can i do?
i really appreciate any help thanks in advance
Hello,
I think I bricked my BQ Aquaris 4.5 phone but I'd like a confirmation:
I did a "wipe data/factory reset", and now my phone boots into a picture of an android robot being updated right after the operator logo. The image is animated, but it seems to be in some sort of "reboot" loop because it flashes black periodically (it doesn't completely reboot the phone tho, because I only see the operator logo the first time the phone boots).
Here are screenshots of what I'm talking about (since I can't link urls because of my new account I'm forced into tricks):
- tinyurl id o9d4h9z
- tinyurl id nenpfz8
When I plug the phone on my laptop, I see /dev/ttyACM0 for a short time but adb fails to connect to the phone (it's basically only available when the operator logo shows when the phone boots). I can't boot in recovery/fastboot/whatever anymore by pressing volume down after I reboot it with power+volume up/down.
I have an external SD card on that phone, is there any hope for me to boot onto it if I format it right? Are there other key combinations/tricks to put the phone on fastboot/recovery? I tried some trick around adb but adb just can't connect to the phone anymore.
Thanks in advance
soft bricked.
I think I may have bricked a phone it says unfortunately the process com.android.phone has stopped

Hello, 5 monts ago i flashed and installed a new ROM on my Prestigio Multiphone 4500. It worked fine except some minor low memory issues but it didn't bother me too much. Today I decided to factory reset my phone. I backed up all of my data and went into options and factory reset, after that my phone turned off for a second. after that I noticed it only shows the bootup screen and the android logo with a blue bar moving underneath it.
I tried the Volume+ and Power button but nothing, after that i pressed Power and Volume- , it launched the phone in factory mode but no option to format or anything. one of the few options were PCBA Test, Full Test, KB Test , Item Test , etc...
After that i formated my memory card but still didn't work.
Please help
First of all, I don't know where to post this thread. Please redirect me if this thread is not for here thanks.
Hi, Im having serious problem with my Samsung S7 phone. what happen was I was trying to install root on my phone, but my TWRP cant find my Internal storage. so I try to search on youtube how. then I saw repairing/formatting the data to exFat/ext4 or something. I did the steps but it shows error while formatting the data and its still on formatting process so there is no any back buttons or anything to cancel it. It take like 10mins on formatting process that keep showing errors so I did turn off my phone.
After that I turned on my phone. TWRP logo shows up and it stays there. It wont go to the main menu of twrp. I cant even turn off my phone after that. if I do the volume down + power, it will just reset to twrp logo. I cant make it turn off so I can go to download mode or safe mode to factory reset coz it doesnt accept any buttons except if I reset the phone [by pressing volume down+power] which directs me to TWRP logo.
Only way to completely turn off is to drain the battery. If I charge it, it automatically opens and lead to the TWRP logo again at get stuck.
