Hi guys!
I'm having a problem with this phone.
Was trying to flash a ROM from cybermaus.
I've rooted the phone with MTKDroid Tools. It was fine, after that i had problems with running FlashTools to run a ROM.
So i tried many methods to ad new ROM, and suddenly my phone, when started up - shows only chinese lenovo logo...
As far as android's Recovery Mode doesn't support "unsigned" ROMs, I've downloaded a "stock_121122_backup.zip" ROM, but unfortunatelly I get a sign verification error :/
ClockworkMod doesn't support this device, so no chance to run a different ROM. Also wiping data and factory restoration doesn't give any progress...
What can I do now? I have a backup made with Droid before Rooting it, but it didn't do a thing.
Is there any way to run "unsigned" ROM from Android's recovery mode??
Please help - after two days of tough fight i'm ready to cry
When trying to use SP Flash to download backup made by Droid i get this:
SP Flash Error (8038)
what is wrong??
hi.
I flashed something wrong on my A750, now it will not start or charge , just black screen (so i can't access CWM/recovery).
can still flash stuff (with the flash tool on my PC, i have the drivers installed and working),
I followed this: www_movilesdualsim_com/foro/threads/11616-Tutorial-LENOVO-A750-flashear-CWM-Recovery-root
but the phone is still not responding.
How do i get to a stage where i can flash the correct rom (e.g. see the CWM/recovery menu) ?
Is there another rom somewhere with a complete system (all i find are roms that are flashed from with in the phone via CWM, that is, without scatter file)
Thanks for helping
resolved
It took a while to find a full rom but once i found one the rest was very simple
I used A750_S148_120428.RAR and flashed it completly
So I have a Sprint Galaxy Mega and it seems as though it may be semi-bricked. It will not boot past the GALAXY MEGA logo. It will just continuously power cycle to and from that logo. If I attempt to put it in recovery, it will say "RECOVERY BOOTING" in blue letters as usual, then power cycle right back to the GALAXY MEGA screen. It will boot into Odin mode and accept Odin files, but after attempting do do a typical "stock Odin" scenario, nothing has changed. I looked around for the Pit but cannot seem to find it. Does anyone has a reliable link to the latest Odin stock restore and the PIT file that matches it?
Maybe an error with your system data. So you can't reboot into recovery ? If you can try to wipe data and cache and reboot.
It may be an abnormal re-partition when flashing stock rock, and then I can't help you (have the i9205 international model). Some members of this section have the Sprint version, try to send them a PM if nobody can help you
Nope, no recovery. I was considering flashing a custom recovery to it to see what it does but I don't wanna kill the phone any more than it already is...
Yes I understand. But flashing custom recovery can solve your problem, only if you can boot on it. I think it can't make more damages to your phone, he just always stuck on boot phase like a brick, but if you don't want to try, wait for a developer making you a PIT file. More safe, the Galaxy Mega have a too poor development support for risk anything...
Well I went ahead and flashed TWRP to it. It will boot into TWRP just fine. Tried flashing the stock L900 ROM zip and it still won't boot.
Well I installed a custom ROM, SlimKat, and the phone boots. If I install the stock ROM located in the following link, OP's signature, the phone goes right back to bootlooping. ???
I need either the stock ROM or a ROM with dialer codes because this phone will be flashed to a regional carrier.
what recovry version you use bro. maybe recovery problem. try use your custom rom to flash another recovery from philz. the latest one. some time recovery dont work properly to downgrade from 4.4.2 to stock 4.2.2.
Great, so with Philz Touch Recovery, I never had problems for downgrade and I do this often for testing roms. Now it should not bootloop if you reflash stock.
I am using "CWM-based recovery 6.0.4.7"
I will try Philz recovery
After trying Philz recovery to flash the stock file I found, it once again bootlooped. Is there another stock ROM floating around somewhere or possibly a custom ROM that has dialer codes such as ##3282# enabled?
No idea... But actually the most complete stock based custom rom is MegaFire I think. Flash V5 (not V5x !) it should be enabled.
I don't see what is the problem while flashing stock rom... Oh ! Maybe you haven't enabled USB Debugging, I forgot to do that one time and I had some issues, in case you try to flash a firmware where Knox or others features are on with a modem without these, may cause bootloop. I've searched for 2 days before solve that little problem...
Have you tried another firmware ? If you can flash custom rom, something went wrong before flash... Odin folder is complete ?
Strange...once again a boot loop after flashing the MegaFire ROM
I'm almost certain I need the PIT file. I cannot find it anywhere.
Well I got the phone to boot from that rooted stock ROM FINALLY. I don't remember for sure but I think what I did was first flash TWRP, then flashed boot.img.tar that I found somewhere, it was listed for the Sprint Mega. I then booted into TWRP and flashed the stock rooted ROM(zip) I mentioned before. It now boots perfectly and everything works except one tiny little detail. No WiFi, no cellular signal at all. Baseband version: unknown in About phone.Already tried flashing the Sprint stock modem from the same download link as the ROM and it didn't work.
I'm having the same problem too dude, I
I download n flash all.the firmware I could find online, since I have no idea what the country of origin is. But most of them work, but no WiFi, Bluetoothand the sim card slot don't read

Yesterday i changed my custom rom(puusy fap v2.5) to Mystic Os v6.
After some time of usage ,phone showed that sim1 is not detected(only 1 sim in phone).
Did Reboots,same problem.
I googled it and and found that my IMEI is showing Invalid.I did Many things like MTK Droid Tools etc.
Nothing Happened .
Then I Used SP Flash Tool And Flashed Stock Rom via scatter file.
I thought it would Solve my Problem But Same Problem.
Then I somewhere Found That by Deleting Nvram Folder In Data In root Section In RootExplorer apk.
I did It And Guess Everything Back Working. Sim1 working and Imei is shown up.
Bt Now another Problem Struck Me.Now I Couldnt go into Recovery .
Not by turn off-volume up and power. Not By Rashr apk.Not By ROm Manager apk.Not By TWRP manager.Not By Flashify.
What Should I Do?? Please Help Me To Fix It.
Well if you got the imei fixed then make its backup and then try to flash stock ROM for your device and further root using Vroot (iroot) and then use rashr to flash the correct recovery.img file for your device.
Well PS the image size check is turned off.
And reboot to recovery

If you were able to boot into TWRP, reboot to recovery > wipe everything > flash this firmware : https://androidfilehost.com/?fid=889964283620754602, next flash any custom rom (download any rom from development section), flash Gapps > reboot! Lemme know how it goes. Good luck.
Not worked...problem remains same
Just download Lazy Flasher .Zip file. and install it via twrp after flashing custom rom .
Your problem will solve for sure.
same happens for me since yesterday. I was using a custom rom since some time and without changing anything after reboot I am running into the same trouble.
Have tried to reinstall official miui rom, lock bootloader etc.
I am afraid this might be a hardware failure.
Hi,
was able to fix my note 4. Have installed twrp 3.1.1-8.0 on my second note 4 and created a backup of all partitions to sd card. Then I have adjusted the serial number of the stored backup to match the one of the broken note 4. After restoring the whole device with the backup files from the working device the reboots are gone.
But it seems like now IMEI, MAC address and Bluetooth address are invalid and/or not correct. Was able to fix at least IMEI.
Have not identified any further issues so far.
BTW: from inside twrp recovery the phone never rebooted.
it seems to be a problem with firmware without firmware the device will boot fine but there wont be bt, fp , calling, sound, wifi etc.
but with firmware it will just bootloop.
