[Q] Lewa Recovery flashed on Jiayu G3

Hello!
I have a problem with my Jiayu G3, I rooted it using Bin4ry's method, and used CWM to flash Android 4.1.2 , all was finished well, but whenever I tried to powe the phone , it always went into a boot loop. I read somewhere to try and flash Lewa Recovery using CWM, and now the G3 won't even boot into CWM and Android.
Any help is much appreciated. Thank you.

I think you will have to flash a new rom using mtk sp flash tool. You may have to try several versions before one works. Jiayu.es (in Spanish) should have all the files you need. Or, hopefully you made a backup and can just reflash cwm recovery and restore.

[Q] MIUI V5 4.8.27: Stuck at boot

I recently flashed my Lenovo P780 which was running 4.4.2 to MIUI V5 4.8.27 ROM using the guideline mentioned in this thread http://forum.xda-developers.com/len...iui-v5-4-6-2-jb-4-2-lenovo-p780-dual-t2795361
I also used the recovery image mentioned this thread http://forum.xda-developers.com/lenovo-p780/help/rooting-tutorial-kitkat-t2835605 using mobileuncle.
I followed every step mentioned in the thread and flashed the rom. Now my device is booting but is stuck at boot. All I can see is MI.com logo. It is stuck like this for more than 30 mins.
I am unable to go back to recovery mode also. I don't know what to do. Please someone help!!
Ok. I solved the issue. Since I flashed the ROM when my Lenovo was running stock kitkat 4.4.2, the MIUI was stuck in bootloop.
What I did was I reflashed my P780 with LIFE ROM V7 using Flashtool. Then I flashed MIUI using TWRP. Now it works fine.

Yes, I also did the same thing. Life ROM is Savior with TWRP recovery built in. Whenever, I had a wrong flash and my mobile is dead, I returned to this by flashing with SP Tools, boot straight into TWRP and then restored my previous working ROM or tried flashing another ROM.
Welcome to MIUI world. I am sure you will enjoy this ROM. Go for OTA update to 4.8.30 which worked like breeze for me. Try the Android V5 Dark theme. You will love it.

Oh! I was going to ask whether OTA update to 4.8.30 was safe. Thanks for letting me know.
My lenovo softbricked after I tried to OTA update MIUI 4.8.27. Then, as you guys said, I installed Life Rom V7 and when I tried installing either MIUI 4.6 and 4.8.27 through TWRP, Roms got installed without any boot issue but I couldn't open any of the apps, even system apps like Dialer and File Explorer. Any suggestions? I would really love to go back to MIUI. May be there is a way to repack it and install through Flashtool?

Soooo... MIUI is for Jelly Bean not for KITKAT.
DO NOT FLASH OVER KITKAT.
IF YOU FLASH OVER KITKAT YOU WILL HAVE ALOT OF PROBLEMS LIKE: YOUR SD CARD WILL NOT WORK(THIS IS THE SMALLEST PROBLEM), BOOTLOOP,BOOTLOADER CORUPTED, ETC ETC.
SO BE WARNED...
If you want to test MIUI do this:
1. Flash stock s124 ROM;
2. Download Framaroot and root your phone;
3. Install Mobileuncle Tools;
4. Get TWRP 2.6.3.0 no other;
5. Flash TWRP with Mobileuncle Tools;
6. Download MIUI and put it in your phone SD Card;
7. Install from market Reboot Manager, give root right and reboot to recovery;
8. From SD Card flash MIUI wipe cache dalvik etc etc;
9. reboot and voila MIUI.
10 Good Luck.

may be that is the problm,again go to recovery format factory reset and then install cm12 and install gapps and then reboot,make sure gapps for lollipop u install
I don't think so. I installed cm12 without gapps worked fine. But still. Try every option u can to restore your phone. Maybe u need to flash gapps for newer version of cm12. Let us know if anything worked for you. Your info coold help others. Good luck mate.

may be the downloaded file is corrupted while it was downloaded, happened to me also. download the file again and do a 'clean' installation.
flashing gapps have no connection whatsoever with rom installation. :good:
Install CM11, boot it up once, then install CM12+gapps without wiping.

Flashing a ROM without gapps will not cause any bootloop issue
how ever you can try these two :
1. If you are using the 27th March build, don't use that, there's some problem with that, if you clean flash that zip, it ll result into a bootloop, use the 28th March build instead
2. If you are still facing a bootloop, make sure that you are using the TWRP 2.8.5 version

Hi, first of all, download the latest build, do a clean flash of all partitions, data, system, cache & dalvik, if you don't wanna loose your data make a backup and restore it only when you have booted your device at least once to make sure it boots, and as recommendation flash a custom kernel after verifying the boot, tell us how it goes Luck!
I tried all the options. I installed the latest build. I cleared cache, dalvik cache, factory reset, etc. But no use its always gets the same situation. Due to the bootloop the device was not detected in Pc so I transferred the cm12 zip to external so card and tried installing it from their. Could dis be a problem?? ? This time I also installed gapps. Please help I want my device back:crying:

find stock rom 4.4.4 somewhere on xda developer site or google u will get it, if u flash android 4.4.2 and then update to android 4.4.4 through sofware update. ur moto e get potentially bricked because u have unlocked the bootloader, when u update stock rom replace the bootlaoder. then u cannot recover ur loving moto e,,then u have only one option to change the motherboard

This you can do if you have installed soak test via putting it in your sd card or installed via OTA(ie if you have updated your bootloader) and make sure drivers are installed
Hope it helped
I believe I have the same problem. I tried going from stock 4.4.4 to cm12. Tested april 1st and april 2nd builds and I always get stuck in boot screen animation for nearly one hour.
Whenever I install the rom I get the following message "detected filesystem ext4 for /dev/block/platform/msm_sdcc.1/by-name/system". I used sideload and the external SD.
Will it brick if I try installing CM11 now after a wipe? Will it be considered a downgrade (even if I never properly booted)?
Sorry if it seems I'm hijacking this thread, but I believe we both have the same problem. I necessary I'll create another topic.
Thanks

no, you can flash cm11, provided you have never flashed the soak test zip anytime before
and about the bootloop, try using the previous version of TWRP, many people have stated that when they tried flashing with the previous version of TWRP it didn't result into bootloop
Hit Thanks if that was helpful
Quick update, with a solution.
Indeed I changed the recovery for TWRP and chose to clean the system in addition to cache, data and dalvik. After that I installed CM12 through sideload and this time it worked fine. Even if I still got the message "detected filesystem ext4 for /dev/block/platform/msm_sdcc.1/by-name/system".
Hope this helps OP as well!

thanks for replying. idea of flashing a stock struck me, but thanks for confirming.
By the way, is any custom rom available for my phone, in order upgrade to lollipop (obviously marshmallow is not available), also is twrp or cwm compatible. I googled a lot but no success.
thanks in advance
i flashed the stock rom, but screen is continously flickering at boot and its stuck at boot:crying:
recovery too is flickering and it is not working properly:crying:
Try completely formatting your phone, instead of overwriting files on previous one. wipe out everything rom, Recovery, Cache and all data. Then do a fresh install.

how to wipe rom and recovery before flashing
you can do with SP flash tool.. Just format all the data.. and reflash the rom
Infocus m2 has a locked bootloader.. Without unlocking bootloader, no development is possible
sorry for late reply,
i tried flashing using sp flash tool long back but that didn't work, and finally on 16th i took it to service center. they flashed it with stock rom, though i don't know how exactly did they do it.
thanks for reply though they didn't work
needed help

Bootloop after Crash [ArchiDroid 3.1.5]

Hey guys,
I have a problem with my Galaxy S III I9300. I have been using a CM 13 rom for some months now, which has worked perfectly fine untli yeserday.
My Phone crashed randomly, which happens sometimes, but after this crash it was stuck in bootloop. I tried to reboot, no result.
After restoring a backup it worked for some time until it suddenly crashed and stucked in bootloop again. Same with factory reset.
I have even flashed a new rom ArchiDroid , via CWM, with the same result.
I hope you guys can help me out with this problem.
Thank you in advance,
GeneralD
Have you tried flashing the latest stock ROM with Odin, performing a factory reset from stock recovery, and then using the phone for a while to verify functionality?

Definitely. Flash to stock should be the first thing you do if your phone goes into bootloop.
OK, I flashed the stock rom & recovery and did a factory reset. Until now everything is working fine, except the "Not registered on network" Error, which I have now
Any solution?
Does the phone show the correct imei? Have you tried manually searching and connecting to a network?

Does it start work 0049..? Do you have a backup of the efs folder? You flashed the latest stock rom?
I have an efs backup of a now destroyed s3.. can it be used for anything like reviving efs borked s3's?
Im sorry guys,
I flashed a old 4.1 stock rom, found the latest 4.3 rom now and the Error is gone
But wont I be able to flash custom roms from now on?
